Description

A kind of plate and frame filter press for ammonium paratungstate production
Technical field
The utility model relates to a kind of solid-liquid separating equipment, especially relates to a kind of plate and frame filter press.
Background technology
Ammonium paratungstate is a kind of important inorganic salt product.Adopt a kind of production technology of ion-exchange legal system ammonium paratungstate roughly to comprise: ball milling, soda boiling, press filtration, ion-exchange, crystallization etc.Wherein press filtration adopts plate compression more.
Filter press, as solid-liquid separating equipment, is widely used in the industries such as pharmacy, biochemistry, food and drink, water treatment, and it has the superiority of good separating effect, wide adaptability.Filter press is divided into plate and frame type filter-press and chamber-type press filter, and plate and frame filter press forms one group of press filtration chamber by filter plate and the filter frame of alternative arrangement.On the corner of filter frame and filter plate, have through hole, after assembling, the passage of complete, can pass into suspension, washings and draw filtrate.The each jug rest in filter frame and filter plate both sides, on loading plate, compresses filter frame and filter plate by hold down gag.Filter cloth between filter frame and filter plate plays gasket seal.By charging pump, suspension is pressed into filter chamber, on filter cloth, forms filtrate, until be full of press filtration chamber.Filtrate is through filter cloth and flow to sheet frame corner passage along filter plate groove, concentrates and discharges.Filter completely, can pass into clean and wash water washing filtrate.Open subsequently plate and frame filter press removal filtrate, clean filter cloth, again compress filter frame and filter plate, start next working cycles.But plate and frame filter press of the prior art, in the time of removal filtrate, need to unload manually, not only operating efficiency is low, also easily damages filter cloth.
Summary of the invention
The purpose of this utility model is just to provide a kind of plate and frame filter press for ammonium paratungstate production, solves problems of the prior art.
The purpose of this utility model is achieved in that a kind of plate and frame filter press for ammonium paratungstate production, comprise support and be fixed on the hydraulic means on support, securing cover plate, guide rail, removable cover is connected with hydraulic means by connecting rod, removable cover, between securing cover plate, be provided with the filter press plate group of several filter plates and filter frame composition, between filter plate and filter frame, filter cloth is housed, filter press plate group both sides are provided with handle, handle is placed on guide rail, filter press plate group is provided with charging hole, filter press plate group bottom arranges a liquid outlet, sheet frame one side surface arranges filter cloth automatic discharge unit, filter cloth automatic discharge unit comprises compressed air hose, on compressed air hose, have some nozzles, compressed air hose communicates with the air inlet in filter press plate group, air inlet is connected with source of the gas by flexible pipe.
Described compressed air hose is connected in length and breadth, and laterally nozzle and longitudinal nozzle are staggered.
Described filter plate both sides arrange four projections around charging hole.
Liquid outlet below, described filter press plate group bottom is provided with feed liquid feeder, and feed liquid feeder is connected with reservoir.
Described filter press plate group below is provided with waste residue accumulator tank.
The beneficial effects of the utility model: owing to adopting the structure of filter cloth automatic discharge unit, after Separation of Solid and Liquid completes, solid residue remains in filter frame inside, open filter frame, nozzle and source of the gas are connected, by compressed air, the filter plate on every filter plate is carried out to on-line automatic winding-up, residue is come off and fall into waste residue accumulator tank, after filter frame inwall is slagged tap, can carry out Separation of Solid and Liquid next time, so the utility model is increased work efficiency greatly, extend filter cloth useful life, simple in structure, equipment investment is few, simple to operate, easy to use, owing to adopting the structure of four projections that arrange around charging hole, make the withstand voltage properties of filter plate better, can effectively extend the service life of filter plate.
