Discussion on the important application of a new generation of cylinder-cone filter, washing and drying two-in-one and three-in-one in the production of raw materials and chemicals

2023/04/12

Now in the market, the older generation of flat-panel two-in-one and three-in-one filters are divided into active and dead chassis. They started to be used early and entered the domestic market early. When they caught up with GMP, they made great contributions. But there are two big problems:
1. Among them, the dead chassis is mainly used in chemical, pharmaceutical and other non-sterile environments and production conditions that do not require very high requirements;
2. The living site is mainly used in the sterile environment of the raw material pharmaceutical factory and the environment with harsh production conditions;
The new generation of cylinder-cone filter, washing and drying 2-in-1/3-in-1 is invented based on the old machine, because it has improved some production defects and dead angles of the old machine, so customers are very recognized. Its main features are rapid and thorough discharge, large filtration area, high filtration efficiency, and low manufacturing cost, which have greatly improved the disadvantages of old machines such as residual discharge and slow discharge.
Wuxi ZhangHua Machinery has fully absorbed foreign advanced technology, and has carried out a lot of design and development work, and finally successfully developed the SR-Tube Cone Reaction Filtration and Drying Multifunctional Machine, the invention patent number: ZL201721560677.6. Realized the production of raw materials and chemical equipment A major breakthrough in technology.
The machine is of barrel-cone structure, and there are heating jackets on the cylinder body and the lower cone, which can heat or cool the materials. The multi-function machine is equipped with a hollow shaft and a variable-angle variable-lead hollow spiral stirring device. Stirring, stirring and lifting the material, pushing out the material when discharging.

A conical filtering device with a relatively complex structure is installed in the lower cone, and a specially designed non-dead angle quick-opening discharge device or a non-dead angle pneumatic discharge ball valve is installed at the bottom of the equipment.
In the reaction and washing stage, the reaction materials are added from the top, and the unique stirring structure can make the materials be stirred evenly in the machine, and are heated or cooled simultaneously by the cylinder jacket, cone jacket, hollow shaft and hollow spiral blade. , so that the material can fully react and wash in the machine. In the filtration stage, the machine can filter and dry the material in the machine by pressurizing or vacuuming, and add washing liquid, so that the material can be automatically repulped and washed several times in the machine, and then pressed dry after meeting the washing requirements.

In the drying stage, the cylinder jacket, cone jacket, hollow shaft, and hollow ribbon heat the material at the same time and vacuumize the top, vacuum-tight and low-temperature drying of the material, and automatically seal and discharge the material after drying.
Features
1. One machine is multi-purpose, and can complete various operations such as reaction, extraction, filtration, repeated filtration, washing, and drying in one machine, and the finished product can be obtained directly.
2. Airtight operation, especially suitable for handling flammable, explosive, poisonous or highly toxic dangerous products and delicious food, biological products and medicines that are not allowed to be polluted.


3. The cylinder jacket, cone jacket, hollow shaft, and hollow spiral belt heat or cool the material at the same time, with high thermal efficiency and low energy consumption.
4. The special stirring screw design can make the material be stirred evenly in each stage of reaction, filtration, washing and drying, so that the working efficiency of the whole machine is very high.
5. In the filtration stage, due to the good adhesion and scraping effect of the ribbon and the filter medium, the material can be filtered under the condition of a thin layer of filter cake, and the filtration efficiency is high.


6. Simplify and shorten the technological process, occupy a small area, and greatly save the investment in workshops and equipment.
7. The operation is convenient, the labor intensity is low, and the processed products are of good quality.
A new generation of cylinder-cone filter washing and drying 2-in-1/3-in-1 workflow
1. Stirring reaction
Add the material (solid-liquid, liquid-liquid or gas-liquid) that needs to be reacted from the feeding port on the top of the equipment, start the motor and reducer, and make the hollow shaft and the hollow ribbon rotate clockwise (looking down from the top). The unique stirring structure can make the materials fully stirred and fully reacted in the machine.

If the materials are to be heated or cooled during the reaction, heat medium or refrigerant can be introduced into the cylinder and the cone jacket, as well as the hollow shaft and the hollow spiral belt. The heating or cooling medium can be continuously circulated to complete the heating or cooling of the material to meet the process conditions required for the reaction.
2. Pressure filtration or vacuum filtration
After the reaction is over, open the outlet of the lower filtrate, pass compressed air or nitrogen gas into the equipment, and filter the reacted solid-liquid mixture under pressure until the materials in the machine are dried.

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.


3. Can be washed and filtered many times
After some materials are filtered, they need to be washed several times. The reaction, filtration and drying multifunctional machine is an ideal equipment for repeated washing of materials. After the material is dried in the machine, the washing liquid can be added to the top washing liquid inlet, Then, through the stirring of the hollow shaft and the hollow ribbon, the filter cake is evenly repulped, and the repulp is stirred evenly before the material is pressed dry.

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 very convenient and the labor intensity is extremely low.
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.
