Abstract
The utility model relates to a filtering device for solid-liquid separation, particularly a leaf filter which can automatically discharge slag. A leaf filter with automatic slag discharging comprises a barrel body, and hollow disc-shaped filter blades which are arranged on a hollow shaft. The utility model is characterized in that the lower part of the barrel body is provided with a rotation filter screen and a rotation mechanism; the rotation screen is arranged on the rotation mechanism. The utility model has the advantages of large filtering area, small volume, simple structure, stable and reliable operation, automatic slag discharging, continuous filtration, labor strength reduction, large filtering strength, high productive efficiency, sealing operation, and material polluting and polluted phenomena elimination.
Description
The utility model relates to a kind of filter plant of Separation of Solid and Liquid, relates in particular to a kind of leaf filter technical scheme that can slag tap automatically.
Filter plant is widely used in technical fields such as chemical industry, pharmacy, weaving, papermaking, food and environmental protection, belongs to unit operating equipment.Press filter type and divide, filter plant generally can be divided into gravity filtration, pressure filtration and vacuum filtration three major types.The gravity filtration floor space is big, and the cycle is long, and is more original; Vacuum filter condition and operating cost are higher, use restricted; Though pressure filtration force of gravity filter efficiency improves, because pressure filtration at present mostly is intermittent apparatus, there is not desirable continuous equipment, not only operation inconvenience, labor strength is bigger, and filter efficiency is low.
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of dynamic filtration technology of utilizing is provided, the realization filter element is slagged tap and continued operation automatically.
The objective of the invention is to be achieved through the following technical solutions, automatically the leaf filter of slagging tap comprises cylindrical shell, is arranged on the hollow plate-like filter leaf on the hollow shaft, it is characterized in that the cylindrical shell bottom is fixed with revolution filter screen and slew gear, the revolution filter screen is placed on the slew gear.
The described leaf filter of slagging tap automatically, the revolution filter screen is with a urceolus that connects with cylindrical shell outward.
The described leaf filter of slagging tap automatically, urceolus is distributed with charging aperture, air inlet, slag notch and cleaning mouth.
The described leaf filter of slagging tap automatically is provided with scraper arm in the cylindrical shell, scraper arm is provided with scraper.
The described leaf filter of slagging tap automatically, it is porose to distribute on the scraper arm.
The utility model filter area is big, and volume is little, and is simple in structure, and working stability is reliable; Automatic discharge can filter continuously, has alleviated labour intensity, and intensity filter is big, the production efficiency height: closed-loop operation, and eliminated material and polluted and contaminated phenomenon.
Further specify the utility model below in conjunction with Figure of description, and provide embodiment.
Fig. 1: the utility model structural representation.
Fig. 2: the A-A cutaway view of the utility model structural representation.
As shown in the figure, automatically the leaf filter of slagging tap, comprise cylindrical shell 3, the inner chamber of cylindrical shell 3 is provided with hollow plate-like filter leaf 4, hollow plate-like filter leaf 4 is placed on the hollow shaft 5, and the shape of hollow plate-like filter leaf 4 can be garden dish type, rectangle or other shapes, the garden that the is shaped as dish type of the hollow plate-like filter leaf 4 of present embodiment, cylindrical shell 3 inwalls are provided with scraper arm 1, and scraper 2 is installed on the scraper arm 1.Cylindrical shell 3 bottoms are provided with revolution filter screen 6 and rotary support 10, and revolution filter screen 6 is fixed on the rotary support 10.Revolution filter screen 6 and rotary support 10 can upright or horizontal settings, the revolution filter screen 6 outer urceolus 7 that connect with cylindrical shell 3 that are with, and connecting mode can adopt the flange connection, and urceolus 7 and cylindrical shell 3 are fused.Be distributed with charging aperture 12 on the urceolus 7, air inlet 11, slag notch 9 and cleaning mouth 8.During work, slurry is pressurizeed by force (forcing) pump, enters in the hollow scraper arm 1 from inlet, and enters upper shell 3 inner chambers by the hole that distributes on the scraper arm 1, under pressure, filters by hollow plate-like filter leaf 4.Filter cake is deposited on hollow plate-like filter leaf 4 surfaces equably, and filtrate sees through hollow plate-like filter leaf 4 and flows out through hollow shaft 5.Motor and transmission mechanism drive hollow plate-like filter leaf 4 rotations on the hollow shaft 5, and filter cake is evenly distributed on hollow plate-like filter leaf 4.Motor and transmission mechanism drive scraper arm 1 axially reciprocating simultaneously, under the effect of scraper 2, constantly remove the filter cake on the hollow plate-like filter leaf 4, make to form thin filter cake on the hollow plate-like filter leaf 4, improve the rate of filtration.The filter cake that cylindrical shell 3 tops scrape enters cylindrical shell 3 bottoms under pressure.Motor and transmission mechanism drive revolution filter screen 6 and rotary support 10 rotates, filter cake is scattered on starlike revolution filter screen 6 wire sides by the charging aperture 12 of urceolus 7, when the starlike revolution filter screen 6 of being with filter cake rotates to air inlet 11 positions, compressed air enters in the urceolus 7 from air inlet 11, under gas pressure, filter cake has obtained further filtration on starlike revolution filter screen 6.Filtrate sees through starlike revolution filter screen 6 and flows out from the liquid outlet on 10 of the rotary supports.When starlike revolution filter screen 6 rotated to slag notch 9 positions, filter cake was discharged from slag notch 9 automatically and continuously.When starlike revolution filter screen 6 rotates to cleaning mouth 8 positions, can carry out the regeneration of filter cake washing and filter screen.Whole process is carried out under continuous constant pressure, can obtain dry filter cake.According to different filtration requirements, select suitable filter medium for use, and can add the clamping cover at upper shell and lower shell, carry out high temperature or filter at low temperature.
