Abstract
The utility model relates to a horizontal plate frame filter capable of ejecting residual liquid by air pressure boost. The horizontal plate frame filter mainly comprises a feeding pump, a storage tank, an air pump and a filtering system, wherein the lower end of the storage tank is connected with a tee joint pipe, one end of the tree joint pipe is connected with a feeding pump through a feeding pipe, another end of the three joint pipe is a filter pulp discharge pipe, the feeding pump is connected with the filtering system through an outlet pipe, and the air pump is connected with the outlet pipe through an air pipe. At the end of the filtering operation of the horizontal plate frame filter, residual liquid in a filter cake can be ejected out through air pressure. Since pressure provided by the air pump is larger than the pressure of the feeding pump, residual liquid can be ejected out, the recovery rate of filtering liquid can be improved, washing time is shortened, and the production cost is lowered; since the filter cake is washed with air, the concentration of the filtering liquid cannot be lowered, namely no waste liquid is generated and the environment is not polluted.
Description
Technical field
The utility model relates to a kind of flame filter press, relates to specifically the horizontal flame filter press that a kind of gas boosting ejects remaining liquid.
Background technology
Flame filter press is the filter plant that is most widely used, and it is widely used in the industries such as wine brewing, food, pharmacy, chemical industry.Flame filter press is simple in structure, and processing ease is stable, easy maintenance; Filter area is selected flexibly, takes up an area few; Filtering accuracy is easy to regulate, to the material strong adaptability.But charging pump provides pressure ratio lower, has arrived the filtration later stage, and because filter cake is compacted, the amount of filtrate of filtration obviously tails off, and filtration time is seriously extended, and some filtrate rests in filter cake, makes the obvious variation of separating effect of filtrate and filter cake.
The utility model content
The purpose of this utility model is to provide a kind of minimizing filtration time, improves the filtrate rate of recovery, and the better gas boosting of filter effect ejects the horizontal flame filter press of remaining liquid.
The utility model is realized by following technology:
Gas boosting ejects the horizontal flame filter press of remaining liquid, comprise charging pump, storage tank, air pump and filtration system, the lower end of described storage tank is connected with three-way pipe, and an end of three-way pipe is feeder sleeve, feeder sleeve is connected with charging pump, and the other end of three-way pipe is the filter pulp discharge pipe; Described charging pump is connected with filtration system by discharge nozzle, and described air pump is communicated with discharge nozzle by air hose.
Described filtration system comprises filter plate, filter frame and filter cloth, is fixed on filter frame before and after described filter cloth and filter plate, has some filter openings on described filter plate and filter frame.
Adopt seal with elastometic washer between described filter plate and filter frame.
Described air hose and discharge nozzle upper end are separately installed with Pressure gauge.
Described storage tank one side is connected with return duct, and described return duct is communicated with discharge nozzle.
Described air pump is air compressor.
Be provided with some control valves on the internal duct of described flame filter press.
The course of work is: filter pulp enters charging pump by pipeline bottom storage tank, charging pump pressurizes to filter pulp, part filter pulp comes back to storage tank by return duct, the filter pulp that refluxes plays stirring action, make the filter pulp in storage tank even, do not precipitate, and pressure keeps stable, can control the pressure of the filter pulp of the filtration system of flowing through by the control valve on the adjusting pipeline, the discharge nozzle pressure gauge shows the pressure of filter pulp; Part filter pulp enters filtration system, and the passage through the filter opening on filter plate, filter frame is linked to be is entered in frame by the little duct in frame, and filtrate is passed filter cloth and arrived the filter plate side, and is moving along the plate surface current, then discharges.Solid is stayed in sheet frame, forms filter cake.When filter finishing, close control valve on discharge nozzle with the protection Pressure gauge, open air pump, air is pressed into air hose enters filtration system, the residual liquid in filter cake is blown out.By regulating the control valve on air hose, control the pressure of air, the pressure of air can show by the Pressure gauge on air hose.
The utility model advantage is: filter when finishing, common flame filter press need to be inputted clear water in machine, in order to the residual filtrate in filter cake is ejected.The filtrate that is ejected in time passing and concentration reduces.In actual production process, the too low filtrate of concentration does not reach requirement, therefore must be as discharging of waste liquid.This had both wasted filtrate, increased again environmental pollution.Simultaneously, the pressure that charging pump provides is lower, and wash time is long, and production cost is increased.The utility model is closed the control valve on discharge nozzle when filtering end, open air pump, makes gas enter filtration system, and filtrate remaining in filter cake is ejected.The pressure that provides due to air pump can be larger than charging pump, can shorten wash time like this, and production cost is reduced; The gas scrubbing filter cake can not reduce filter liquor concentration, namely can not produce waste liquid, and is free from environmental pollution.
