Sealing device for gate type continuous vacuum/pressurized charging and discharging treatment

Abstract

The invention relates to a flashboard sealing device for charge and discharge machining in vacuum and pressure continuously, belonging to mechanical equipment machining area such as food, traditional chinese medicinal materials, chemical engineering and wood so on, mainly comprising charge (discharge) port, pressing board of charge (discharge) port, charge (discharge) pressing board, charge (discharge) middle frame, middle frame, collecting device, charge (discharge) sealing plate, reciprocating cylinder, U-shape sealing ring, charge (discharge) pressure fluid pipe, electromagnetic valve and forvacuum port so on. It is the sealing device that can maintain the vacuum degree/pressure under continuous charge and discharge of materials. It can applied in various equipments with different purposes such as food sterilization, fried deoiling machining, freezing machining in deep cold and precooling machining so on. It is adapted in various machining processes.

Description

technical field [0001] The invention belongs to the field of mechanical equipment processing such as food, Chinese medicinal materials, chemical industry and wood, and relates to a sealing device capable of maintaining vacuum degree / pressure under the condition of continuous feeding and discharging of materials. [0002] Many kinds of products are required to be processed under a certain degree of vacuum / pressure, and it is also necessary to keep the degree of vacuum / pressure constant under the condition of continuous feeding and discharging of materials, which can improve product quality, reduce energy consumption, and increase the yield. High, this type of sealing device is really needed in the existing product processing equipment, and can be applied to equipment for different processing purposes, such as: continuous high-temperature canned food sterilization; continuous vacuum frying and deoiling processing; continuous deep-freezing and freezing processing; continuous Vacu...

Problems solved by technology

[0003] There are many forms in the existing literature records, such as U.S. patents: 3812775, 4059046, 4844931, 4852475, 5182982, 5988051; European patents: 0409643A, 58183048A; , the sealing devices of the continuous vacuum inlet and outlet material processing of the above-mentioned published documents have their own characteristics. Although the methods are different, their structures all adopt the gate type or the inlet and outlet seal processing devices with a decompression transition. Complexity, high processing precision requirements, high manufacturing costs, and it is difficult to achieve high vacuum / pressure stability, and various equipment have different processing requirements for different material types, shapes, and purposes, all of which have certain limitations , it is very difficult for technology promotion
