Description
Technical field
The utility model relates to a kind of high pressure variable capacity filter.
Background technology
At present; The sludge high-pressure dehydration equipment of sewage treatment industry is in operation and has bigger defective, and its key components and parts spring causes spring breakage owing in expressing process, receive the rotation side force of filter element through regular meeting; Make filter element ineffective, and it is big to change the spring workload.Intrinsic in addition drainage passage is little, and a large amount of filtered water can't all be got rid of, and final mud cake still has part water to discharge.Cause the plant maintenance amount big, the shortcoming that filtration time is long.
The utility model content
The purpose of the utility model is to provide a kind of high pressure variable capacity filter, and it is big effectively to solve existing high-pressure filteration unit maintenance workload, the problem of drainage impeded drainage.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of high pressure variable capacity filter; Comprise annular outer plate, plate core, base plate, said plate core is arranged in the inner ring of annular outer plate, and the right side of said plate core is fixedly connected with base plate; Leave flexible gap between said annular outer plate and the base plate; Be provided with at least one elastic device between said annular outer plate and the base plate, be provided with the stopping means that prevents that both from separating between said annular outer plate and the plate core, the left side of said plate core and the right side of base plate are equipped with filter cloth.
Preferably, said stopping means comprises contacted first positive stop lug boss and second positive stop lug boss, and said first positive stop lug boss is arranged on the right part of annular outer plate inner ring, and said second positive stop lug boss is arranged on the left part of plate core excircle; Utilize boss spacing, be provided with simple and convenient.
Preferably, said first positive stop lug boss, second positive stop lug boss are annular boss; Guarantee that annular outer plate can not separate because of elastic device with the plate core.
Preferably, said elastic device is a spring, is evenly equipped with some springs between said annular outer plate and the base plate; Stressed even.
Preferably, the left side of said annular outer plate is provided with O-ring seals, also is provided with O-ring seals between said annular outer plate and the plate core, also is provided with O-ring seals between said filter cloth and the plate core; Further enhanced leaktightness makes the liquid of squeezing flow out from the place of appointment.
Preferably, said base plate is provided with at least two locating holes; Convenient a plurality of devices are located by connecting together.
Compared with prior art, the utility model has the advantages that: can make the material squeezing in the filter element under the high squeeze force, sealing effectiveness is obvious, and the filter cloth life-span prolongs, and the drainage draining is unobstructed, and spring life prolongs, and maintenance is little, and is simple in structure.
