MY series closed & pressurized crystal filter washing drying integrated machine,known as "three-into-ine machine",is well suitable for various materials,especially for the treatment of such materials as thick liquids as well as toxic,volatile and pollutant materials.Integrating filtering,washing and drying into a whole,the machine enjoys the features of simplified technological process,higher production efficiency,material pollution prevention,easy discharging,easy realization of mechanical/electrical integration,etc.Besides,with this machine the floor space of the clean workshop required druing the whole production process can be greatly reduced and thus,customer's infrastructure investment cost can be singificantly lowered.This machine finds wide application in such trades as pharmacy, pesticide, biochemistry, dyeing,food, beverage, fine chemicals,chemicals refined from farm products,polymers and resin products,etc.It is especially suitable to the production with high purity and with small amount but multi-varieties.This machine is designed,developed and manufactured by the company itself and has come into actual application,filling in the domestic gap in terms of same kind of products and substituting for imported one.It enjoys broad prospect in the application in separating toxic,harmful and pollutant materials.

The operating process of MY series closed & pressurized crystal filter washing integrated machine can be divided into four stages:

• Filtering:Under the action of the pump,the material to be separated enters the machine and under the pressure of the pump,initial filtering starts.When the feeding is finished,switch on compressed air,and under the pressure of the compressed air,filtration is conducted for a second time and the solid/liquid separation of the material is realized.For the filtering medium,filter cloth or sintered stainless steel multi-layer filter disc of various sizes and with different media are available for your choice in accordance with the properties of different products and materials.The filter disc is fixed on the lower cylinder of the machine and can be cleaned and replaced.When the product is changed,only the replacement of filter plate is required,and thus one machine can be used for several products.The filter cake formed is flattened by means of specially-made scraper device,eliminating any cracks on the cake,enabling the cake to have uniform distribution and consistent thickness,and enabling thorough separation between the solid and liquid.
• Washing:Through specially-made washing mechanism,the cleaning liquid thoroughly and uniformly distributes inside the machine,enabling the cleaning of the inside of the machine and washing of the material.Under the blending action of the scarper mechanism,the filter cake,layer by layer,is thoroughly mixed with the cleaning liquid,finally forming pasty turbid liquid and the filter cake being thoroughly cleaned.Depending on specific materials,repeated washing can be chosen.
• Drying:After thorough washing,input compressed air to dry the filter cake.For the material to be dried,input steam or hot-air(nitrogen gas) to dry the material under the action of vacuum.
• Discharging:Under the action of the scraper mechanism,the dried filter cake is scraped up and driven to the side discharging valve position and then comes out of the machine.

• This machine is intended for integral installation.In the case of separate assembling required by transportation,the correctness and exactness must be ensured.
  
  The machine must be horizontally installed on the concrete foundation and the structural member.
  

• Make sure that the lock bolts are fastened to ensure the safety.
• Make sure that the discharge valve is closely shut.
• Make sure that the liquid outlet valve is closely shut.
• Check the electric control system and the pneumatic control system.(The action of all the electric components should be prompt and reliable,and there is no air leakage of the pneumatic system.)

• After finishing the checking of the above items,turn on the feeding valve and put into the material to the limited level.
• After the crystallization,turn on the liquid outlet valve and turn on the air inlet valve to let the compressed air in for the filtration.
• After the filtration,turn on the washing valve for washing.
• After the washing,turn on the air inlet valve to let the compressed air in for the filtration.
• If drying is necessary,turn on the ventilation valve and let steam or hot water enter the sleeve for heating.
• After the heating,turn on the discharging valve and the scraper rotattes for discharging.
• After the discharging is completed,reset the scraper to start the next cycle.
  

• It is necessary to frequently check the work condition of the pneumatic system and the electric system.
• If any leakage should occur at the seal,tighten the end nuts.
• Regularly put lubricant oil to the speed reducer box.
