High-efficiency cylinder-cone filter washing two-in-one and three-in-one multi-functional equipment will soon become the mainstream of the market
At present, the filtering and washing two-in-one and three-in-one devices widely used in the pharmaceutical industry use flat sintered mesh to filter the interior, and the internal solid residues are discharged out of the machine through the dual functions of lifting and rotating the internal agitator. , but the conventional device not only has a poor filtering effect, but also is prone to filtrate leakage, and the user's washing is troublesome, which is not conducive to the user's repeated operations. Moreover, the conventional two-in-one filtration and washing method is often unable to quickly discharge the filtrate, and it is not convenient for the operator to completely clean the device, and it is also prone to leakage and waste of the filtrate.
The high-efficiency cylinder-cone filter and washing two-in-one and three-in-one multifunctional equipment developed and produced by Wuxi ZhangHua Machinery can form a very thin filter cake on the surface of the filter medium or filter under the condition of no filter cake. The filtration rate per unit filter area The material is very high, and the material can be filtered and washed repeatedly repeatedly, so that the equipment cost, floor area, labor intensity, energy consumption, etc. are greatly reduced.
The high-efficiency cylinder-cone filter and washing two-in-one and three-in-one multifunctional equipment developed and produced by Wuxi ZhangHua Machinery, the top cover, cylinder body and cone-shaped spherical shell are connected to each other through flanges to form a closed container, and the stirring drive device drives the central shaft And the spiral stirring device around the central axis rotates to drive the material to realize the stirring operation; the filter device on the outer wall of the container can filter the material, and the filtrate passes through the filter device and is collected by the filtrate collecting plate, and is discharged from the cylinder through the filtrate outlet. The conical spherical shell at the bottom of the container cooperates with the bottom stirring device that fits the inner surface of the spherical structure of the conical spherical shell, so that there is no dead angle in the operation of the material in the container, which makes the stirring more uniform and does not cause waste of materials .
High-efficiency cylinder-cone filter washing two-in-one, three-in-one multifunctional equipment structure and working principle
Cylinder-cone filtering and washing two-in-one cone or cylinder is equipped with multi-layer orifice plates and filter media to form a filter device. The inside is equipped with a stirring shaft and a variable-angle variable-lead screw stirring device. Stirring, lifting and scraping operations are performed, and the filter cake is automatically pushed out during discharge.
This machine can carry out vacuum filtration or pressure filtration. During the filtration process, the scraper in the machine continuously scrapes the filter cake on the filter screen, so that the material is filtered under the condition of a thin layer of filter cake, and the filtration rate is very high.
If the material needs to be washed, the slurry can be filtered and dried in the machine first, then add the washing liquid, and use the scraper, agitator and extrusion screw in the machine to re-slurry the filter cake, and then pressurize or The reslurry is filtered into a filter cake by vacuuming.
In this way, re-slurry filtration is repeated many times to wash the material thoroughly, and finally all the filter cakes are extruded out of the machine.
High-efficiency cylinder-cone filter washing two-in-one, three-in-one multi-functional equipment process flow
1. Pressure filtration or vacuum filtration
Feed the solid-liquid mixture crystal slurry produced by the upstream reactor or crystallization equipment into the tank of the three-in-one equipment, open the lower filtrate outlet, and feed compressed air or nitrogen into the equipment to add the reacted solid-liquid mixture. Press and filter until the material in the machine is pressed dry. Vacuum can also be drawn at the outlet of the filtrate to vacuum filter the material until the filtrate is drained.
When filtering, the hollow shaft and the hollow screw belt can be rotated clockwise (viewed from the top) to lift the material, and the hollow screw belt can limit the thickness of the filter cake layer when rotating, so that the material is in a thin filter cake Filter under layer conditions to increase the filtration rate. For materials that are easy to filter, it is not necessary to stir when filtering, and the materials are directly filtered to dryness.
2. Can be washed and filtered many times
?? After some materials are filtered, they need to be washed many times.
The reaction, filtration and drying multifunctional machine is an ideal equipment for repeated washing of materials. After the material is pressed dry in the machine, the washing liquid can be added to the top washing liquid inlet, and then the filter cake is evenly repulped through the stirring of the hollow shaft and the hollow ribbon, and the material is pressed dry after the repulping is evenly stirred. If washing once is not enough, it can be washed several times. At this time, the above steps can be repeated many times. The operation is convenient and the labor intensity is extremely low.
Washing materials in the above method is called batch washing method. Since the material is pressed dry and then washed with washing liquid, although the valves are opened and closed a little more times during operation, less washing liquid is used. The machine can also continuously wash the materials, that is, continuously press the washing liquid with a pump or other methods, and use the pressure of the washing liquid to filter, while the hollow shaft and the hollow ribbon are continuously stirred, and the filtrate is continuously discharged from the filtrate outlet until Until the washing requirements are met, the filter cake is finally pressed dry.
This continuous washing method generally uses more washing liquid than intermittent washing, but it is more convenient to operate.
4. Vacuum drying and discharging
The filter cake that is filtered or washed, filtered and dried remains in the machine. At this time, the heat medium is passed into the cylinder jacket, cone jacket, hollow shaft, and hollow screw belt to heat the material. At the same time, the hollow shaft and hollow screw The belt still rotates in a clockwise direction (looking down from the top) to lift the material up and stir it fully, while vacuuming is carried out on the top of the equipment to make the material dry in a vacuum-tight manner inside the machine. Since the hollow shaft and the hollow ribbon are heated from the inside in addition to the jacket heating, and the drying is carried out under vacuum conditions, the drying efficiency is very high.
After drying, open the quick-open discharge port at the lower part of the equipment, and make the hollow shaft and hollow ribbon rotate counterclockwise (looking down from the top), and the dried materials in the machine will be automatically pushed to the discharge port. So far, the reaction, filtration, washing and drying processes of a batch of materials are completed.
High-efficiency cylinder-cone filter washing two-in-one, three-in-one multi-function equipment Performance characteristics
