Cylindrical cone filter washing and drying three-in-one three-in-one multi-functional filter operating instructions and maintenance
The barrel-cone filter, washing and drying three-in-one has many advantages. It can complete various operations such as reaction, extraction, crystallization, filtration, washing, repeated washing, filtration and drying in a fully enclosed state, so that the process The process is greatly shortened, and the investment in plant, floor space, equipment, process pipelines, valves, etc. is greatly saved. It is especially suitable for flammable, explosive, toxic or highly toxic materials, or materials that are harmful to human bodies and where pollution is not allowed. Processing of delicious food, biological products, pharmaceuticals, etc. The machine can directly obtain the finished product in a fully enclosed state, which not only avoids the troubles caused by the connection and material transportation of several separately operated unit equipment such as reaction, filtration, washing, and drying, but also Reduce material loss and waste to zero.
Cylinder-cone filter washing and drying three-in-one three-in-one multi-functional filter The manufacturer should formulate the operation, maintenance and maintenance procedures of the equipment according to the operation manual and process operation requirements of the three-in-one equipment.
In addition to on-site installation and commissioning of equipment, the after-sales engineers of the three-in-one equipment manufacturer also need to train operators and maintainers who use the equipment of the manufacturer, so that they can master the operation, use and daily maintenance of the three-in-one equipment. Precautions.
Cylinder-cone filter washing and drying three-in-one three-in-one multi-functional filter points for operation and use
(1) For three-in-one equipment with explosion-proof requirements, replacement process operation is required before feeding. Vacuum the three-in-one tank first, then add nitrogen into the tank, and when the pressure reaches the set value, it will be vented through the vent.
Repeat the above steps until the detected oxygen content in the tank meets the process requirements.
(2) In the vacuum drying process of the three-in-one equipment, in order to maintain the balance of the pressure difference between the upper and lower filter media, it is necessary to install a vacuum valve and a balance valve in the vacuum process pipeline. When the vacuum valve and balance valve adopt pneumatic or electric valves, safety interlock design should be carried out for the electrical control program. Only when the balance valve is fully opened and the program receives a feedback Feedback signal and then close the balance valve.
When the vacuum valve and balance valve are manually operated, the operator should operate in strict accordance with the process to avoid damage to the filter medium of the equipment during the vacuum drying process. The commonly used filter medium is metal sintered mesh. In addition to ensuring the balance of the pressure difference between the upper and lower sides of the filter medium, it is also necessary to avoid hard objects in the material, which will scratch the filter medium and the inner wall of the equipment during stirring.
(3) If the discharge valve is operated manually, the safety interlock design cannot be implemented, and the operator should strictly follow the operation procedure to avoid dangerous operations with pressure.
(4) The material of the three-in-one equipment in contact with the material is generally S30408, S31603 austenitic stainless steel, S2205 duplex stainless steel and C276, C22 Hastelloy material. For three-in-one equipment with various products, before replacing the product, the manufacturer of the equipment needs to verify whether the material of the three-in-one equipment can meet the process requirements of the product to be replaced, and should determine the rationality of equipment sharing to avoid equipment corrosion and failure caused by blind production. recovered economic losses.
Cylindrical cone filter washing and drying three-in-one three-in-one multi-function filter daily maintenance
Proper daily maintenance of the three-in-one equipment can reduce maintenance costs, reduce product costs, and help improve production efficiency.
The daily maintenance of three-in-one equipment mainly includes keeping the surface of the equipment clean, lubricating equipment parts, tightening screws, and checking the operation status of parts, safety accessories, instruments and electrical appliances.
(1) Equipment surface cleaning
The 3-in-1 device has a matt, polished or brushed outer surface without any burrs and is easy to clean. During the cleaning process, the outer surface should be kept dry to prevent the cleaning solution from penetrating into other parts of the equipment and destroying the lubrication effect; do not wash the up and down operation control button box, electrical instruments, etc. with water to prevent the original electrical components from being burned.
The inner surface of the three-in-one device is flat and smooth, which is more conducive to cleaning. When the three-in-one equipment in the food or pharmaceutical industry continuously produces the same product or several batches of continuous production in stages, it is advisable to select an appropriate interval to clean the equipment to prevent the emergence and legacy of pollutants and to give the next batch of Production brings risks. When changing batches of pharmaceutical products, the equipment must be thoroughly cleaned.
Before non-specialized equipment is replaced with production products, the equipment must be thoroughly cleaned to prevent cross-contamination. The cleaning agent used should not cause any corrosion to the equipment body, and the operating procedures should clearly stipulate the type and amount of cleaning agent.
③ Mechanical seal bearings and bushings are recommended to be lubricated with grease. Grease is easier to retain in bearing seats and bushings than oil. The selection of lubricant in each lubrication point in the three-in-one equipment should comprehensively consider factors such as operation and ambient temperature. When the temperature is low, a lubricant with relatively low viscosity should be selected.
In addition, if the lubricant used in the three-in-one equipment is required not to pollute the product, food-grade or equivalent lubricants can be used.
Except for the welded parts, the general parts in the three-in-one device are connected by threads. The tightened screws will loosen when the equipment is running for a long time. The loosening of the screws may lead to incomplete sealing of the three-in-one equipment, or the gap between certain moving parts is too large, so that the equipment cannot run safely and reliably. Therefore, it is necessary to timely Tighten loose screws.
This kind of small work requires eye and hand diligence, timely discovery and timely processing.
Visual inspection mainly checks whether there is oil leakage in the oil cylinder, oil pipe and its joints, and the hydraulic station; whether the hydraulic oil level is higher than 1/2 of the sight glass, whether the oil temperature of the hydraulic station is less than 55°C; whether the oil level of the reducer chassis reaches the specified level, Whether there is oil leakage in the oil seal of the reducer During operation, whether there is any leakage at each sealing point and each nozzle.
The listening test mainly checks whether there is any abnormal noise during the operation of the hydraulic cylinder, the gear of the reducer, and the bearing; whether there is any abnormal noise during the operation of the mechanical seal bearing and the friction pair; whether there is any abnormal noise during the operation of other parts of the equipment.
The nozzle of the three-in-one tank is generally equipped with a pressure gauge to display the pressure in the tank. During its use, the following conditions should be stopped: the pointer does not return to zero or loose, the dial glass is broken, the scale is blurred or the lead seal is damaged. The verification and maintenance of the pressure gauge must comply with the regulations.
The barrel-cone filter, washing and drying three-in-one will encounter various problems and failures in the production process. The establishment of scientific operation, maintenance and maintenance procedures can not only eliminate some of the problems encountered in the production process of the equipment, but also Accidents can be eliminated in the bud, and economic losses caused by operational errors or lack of necessary maintenance can be avoided.
