The solid and liquid separation device comprises a stander, a filter barrel supported by the stander, an upper filter barrel cover which can move in the filter barrel up and down, a lower filter barrel cover, a moving device of the lower filter barrel cover and a filtrate inlet connected to the filter barrel. The solid and liquid separation device has a simple structure, high working efficiency, a good solid and liquid separation effect and high automation degree.
Description
(1) technical field
What the present invention relates to is a kind of equipment that in environment-protecting industrial, is applied to the sewage Separation of Solid and Liquid.
(2) background technology
In existing trade effluent place process, mainly reach quick separation purpose at present through pressure differential; Filter plant totally is divided into vacuum and two types of pressurizations, and vacuum types is commonly used has rotating cylinder, disk, a horizontal belt etc., and pressurization is type commonly used has press filtration, squeezing, dynamic filtration and rotary-type etc.
The filter of vacuum filter is installed in by some filter screens and is contained on the hollow shaft, and the cavity of filter screen is communicated with the filtrate hole of hollow shaft, drives filter screen at the groove hollow mandrel that is full of mother liquor and rotates, successively through filtering area, dry section, filter cake obscission zone.When the Xie net during through filtering area the filter screen cavity link to each other with vavuum pump, make the ectonexine of filter screen form pressure reduction down in the effect of bleeding of vavuum pump, Separation of Solid and Liquid is at the surface of filter screen formation one deck filter cake.When filter screen leaves liquid level and is in dry section, still link to each other with vavuum pump, under vavuum pump continuation effect, let air permeation filter bag cake gap and take away moisture content, filter cake is further dewatered, filter screen is in and makes the filter screen cavity stripping filter cake that links to each other with pressure fan when blowing off the district.Deficiencies such as vacuum filter is to be in the continuous course of work in limit on the whole, handles but belong to suction type in the separation process, makes the complete machine costs and poor dehydration results, filter cake disengaging rate is low, the filter cake liquid content high, and disposal ability is less than normal, power consumption and noise are big;
Filter press makes pressure oil charge into hydraulic cylinder through hydraulic system; And promote piston and a plate moves forward; The multi-disc filter plate is compressed, make adjacent filter plate filter screen constitute many hollow filter chambers, feed pump is sent into the hollow filter chamber with mother liquor from managing through material of tailgate; Pressure-filtering process begins after all hollow filter chambers are full of mother liquor, and the pressure that is produced by feed pump carries out Separation of Solid and Liquid under the effect of filter screen.Solid particle is stayed filter chamber, and filtrating is flowed out through screen pack, filter catch-drain, and the pressure-filtering process time is by mother liquor characteristic and the decision of pressing technology operating condition; After reaching the stipulated time, stop feed, after a period of time that keep-ups pressure, hydraulic cylinder begins the back to operation; A plate is return original position; Each hollow filter chamber is opened successively, filter cake is come off through self gravitation, must answer said process again; Filter press comprises in an operation cycle: compress filter plate, pan feeding, pressure filtration, unclamp the filter plate and the several courses of work of arm-tie discharging.In an operation cycle process, have only pan feeding and pressure filtration process to be in the direct mechanism of Separation of Solid and Liquid, other process is complementary process, makes greatly reducing with efficient of filter press; Can make the filter chamber poor sealing when disengaging is stained with solids at the sheet frame edge like filter cake simultaneously, make pressure filtration pressure not enough, and the masterbatch injection is impacted; Generally also there is intermittently operated in filter press, and production efficiency is low, and labour intensity is high, and the filter cloth loss is fast, filter cloth is installed deficiencies such as trouble.
(3) summary of the invention
The objective of the invention is in order to solve the problem of the above existence, a kind of simple in structure, high efficiency, good effect of separating solid from liquid, sewage equipment for separating liquid from solid that automaticity is high are provided.
The technical scheme that realizes the object of the invention is:
It comprises the filtrating charging aperture in frame, the cartridge filter by frame support, the mobile device that can in cartridge filter, move up and down cartridge filter loam cake, cartridge filter lower cover, cartridge filter lower cover, the access filter vat.
Special is:
Expansion gear is arranged in the cartridge filter.
Said expansion gear is one or a few expansion tube and inflating medium import.
The mobile device of cartridge filter lower cover is for reaching parallel movement apparatus up and down.Reach up and down parallel movement apparatus be meant can let the cartridge filter lower cover up and down with parallel constructional device.
Cover its control device that moves up and down of control on the filter vat.For example the filter vat loam cake connects the control oil cylinder, and the control oil cylinder can make loam cake slide up and down at the filtration barrel body inwall.
Cartridge filter is an open cartridge filter and screen pack within it.Concrete mode can be barrel wall and has some fluid holes, and the cylindrical shell installed inside has filter net cloth.
The advantage of present technique scheme has:
1. between the 35%-60% when the effective time of filter pressing of existing filter press is merely full work; Amount has part-time and part hollow filter chamber material to separate in time of filter pressing and is in wait state together; And the present invention is in continuous pan feeding pressure-filtering process of all the period of time by the operation of a plurality of separate component matching coordinative to complete machine; Filter press has only the pressure source operation of single pump as press filtration simultaneously; And this device can have three pressure sources (pan feeding pump, upper sealing plate, expansion gear) press filtration simultaneously; Also can interiorly at any time carry out press filtration, thereby greatly improve the pressure efficiency of operation by a certain pressure source.
2. this device can be surveyed device as controlled condition through various bolts in operation process; All can control each operation process automatically by controller; Eliminate the complementary work operations of personnel of original press filtration or vacuum equipment, reduced labour intensity, realized high intelligent high automation.
3. this device output filter cake compares with straight null device and belt press filtration, because repeatedly press filtration makes output filter cake liquid holdup low.
(4) description of drawings
Fig. 1 is the main cross-sectional schematic of looking of the present invention;
Fig. 2 is a schematic perspective view of the present invention.
(5) specific embodiment
Further specify below in conjunction with accompanying drawing, but be not limited only to this.
It comprises frame 1, the cartridge filter 2 by frame 1 support, cartridge filter loam cake 4, cartridge filter lower cover 9, inserts the filtrating charging aperture 7 in the filter vat 2.
In loam cake 4 upper shells 2, expansion gear 6 is installed, expansion gear 6 is four expansion tubes and opens the inflating medium charging aperture 8 on loam cake 4.
The mobile device of cartridge filter lower cover 9, for lower cover 9 is connected with the control oil cylinder 10 that lower cover 9 is moved up and down, control oil cylinder 10 is installed on the movable support bracket 11, and movable support bracket 11 is embedded in movable support bracket 11 is shifted out on the moving track 12 under the cartridge filter 2.
