Description
Technical field
The present invention relates to filter press fields, and in particular to the novel reinforced air-dried plate and frame filter press of one kind and its filter-pressing method.
Background technique
A kind of liquid that plate type pressure filter is widely used in the industries such as chemical industry, sugaring, pharmacy, food, ore dressing, sewage treatment is solid
The equipment of body two-phase laminated flow.Its broad form has sheet frame, van-type and is combined by the two.Its groundwork process are as follows: filter press
Each filter chamber be made of multiple groups filter plate；Under the pressure of delivery pump, the filter pulp of certain moisture content is sent into each filter chamber, while by filtering
Filter cloth in room separates solid and liquid, and liquid passes through the fistulae discharge that filter plate bottom is arranged in, and solid is retained in filter chamber
Interior to form the low filter residue of moisture content, when filter plate separates, the less filter residue of moisture content is fallen from filter chamber.Filter press is in whole service
It is that the pressure of delivery pump is leaned on to carry out work in the process, filter pulp constantly will be pressed into filter chamber by delivery pump, could be extra moisture
It presses out.When beginning, a large amount of filter pulp is pressed into filter chamber by delivery pump, with the increase of filter residue in filter chamber, the filter pulp that is pressed into every time
Less and less, the work of delivery pump only serves the effect of pressure maintaining.But pressure when playing pressure maintaining effect due to delivery pump is limited,
Cause filter residue moisture content high, energy consumption is high for the processes such as subsequent drying, waste of resource or transport processing process substantially increase transport at
This.Therefore, the main task that filter residue moisture content is filter press is reduced as far as possible.
Summary of the invention
Present invention solves the technical problem that being that pressure when delivery pump plays pressure maintaining effect is limited, lead to filter residue moisture content
Height, energy consumption is high, waste of resource or transport processing process substantially increase transportation cost for the processes such as subsequent drying, provides a kind of big
The big reinforcing for reducing filter residue moisture content air-dries plate and frame filter press and its filter-pressing method.
In order to solve the above technical problems, the present invention adopts the following technical solutions: a kind of strengthen air-dries plate and frame filter press, including
Delivery pump, free flow plate, undercurrent plate and reinforcing air-drying device, the free flow plate and undercurrent plate are arranged alternately, on the undercurrent plate

The top of plate is equipped with air hose via hole, lower part is equipped with free flow water outlet.
The undercurrent water outlet is connected to outlet conduit, and outlet conduit is equipped with valve, the free flow water outlet
Outside is equipped with tap.
The central coaxial of the free flow plate and undercurrent plate is equipped with feed opening, and feed opening is connected with the feeding pipe of delivery pump
It is logical.
The internal diameter of the feed opening is 150-180mm.
Plate heart supporting point is symmetrically arranged on the inside of the inside of the free flow plate and undercurrent plate.
Sealing rubber ring is symmetrically arranged on the free flow plate and undercurrent plate.
It is a kind of to strengthen the filter-pressing method for air-drying plate and frame filter press, comprising the following steps: 1. to feed, by delivery pump to filter plate
Interior conveying raw material, stops after feed pressure reaches 0.8MPa, and feeding device is closed, and completes raw material and is dehydrated for the first time；
2. filter plate rear portion be equipped with push plate, push plate by hydraulic cylinder push control: push plate move forward, reduce every group of free flow plate with
The distance between undercurrent plate realizes that second of filter-press dehydration to raw material, raw material are formed between free flow plate and undercurrent plate
Filter cake；
3. opening the air compressor for strengthening air-drying device, compressed air enters from the air inlet on undercurrent plate, after penetrating filter cake
From the free flow water outlet discharge on free flow plate, the reinforcing air drying process to filter cake is completed.
Step closes the valve on outlet conduit after 3. the reinforcing air-drying device is opened.
Step is after 3. the compressed air enters from the air inlet on undercurrent plate, then from top to bottom, from filter cake side to
The other side penetrates filter cake, and gas-liquid mixed vapour finally is discharged from the free flow water outlet on free flow plate.
The present invention, which is arranged, strengthens air-drying device, increases the reinforcing baking step of filter press, and free flow plate and undercurrent plate are pairs of
Setting, guarantees not to be leaked after compressed air enters undercurrent plate, and compressed air often passes through a filter cake and is discharged in time from free flow
Mouth discharge reduces compressed air running resistance while guaranteeing to strengthen drying effect；Contained by the filter cake after reinforcing baking step
Water rate reduces by 10% or more compared with the filter cake moisture content that conventional method filters pressing obtains, and greatly reduces the energy consumption or fortune of subsequent drying course
The transportation cost of defeated process.
