Description

A three-wash belt filter

technical field

The utility model relates to a belt filter, in particular to a three-wash belt filter.

Background technique

The belt filter is a highly automated solid-liquid material separation equipment. The filter cloth or filter screen is used as the medium to make the slurry horizontally arranged on the filter medium, and the solid-liquid separation is realized by using the gravity of the slurry and the penetration of the liquid. . However, when some slurries are filtered, the particulate chemicals contained in the slurries will be trapped in the tiny filter holes on the filter cloth. Usually, there is only one cleaning tank for filter cloth cleaning, and the slurry residue on the filter cloth will directly enter the cleaning tank, which will cause the water quality in the cleaning tank to be turbid and cannot achieve a good cleaning effect. Ways to clean up will affect the filtering effect of the filter cloth. In addition, usually, the cleaned filter cloth is directly used to filter the slurry again. Since the filter cloth is covered with water during the cleaning process, this will also affect the filtration of water in the slurry.

Contents of the invention

The purpose of the utility model is to provide a three-wash type belt filter, so as to solve the problem of residual particulate matter in the existing belt filter due to incomplete cleaning, and avoid affecting the filtering effect.

A three-wash belt filter, including a frame, a transmission roller, a filter cloth, a primary cleaning tank, a chemical residue cleaning tank, a secondary cleaning tank, a squeeze wheel, a guide wheel at the bottom of the pool, a spray pipe, a pumping pump, The guide wheels outside the pool; the bottom of the frame is placed in turn from right to left for the primary cleaning pool, the chemical residue cleaning pool, and the secondary cleaning pool. The bottom guide wheels are installed in the primary cleaning pool and the secondary cleaning pool. The upper part of the cleaning tank is equipped with guide wheels outside the pool, and the two ends of the upper part of the frame are equipped with drive rollers, and filter cloth is laid on the drive rollers; the characteristic is that there is a pump in the chemical residue cleaning tank, and the pump is connected to the chemical tank through a water pipe. The spray pipe above the cleaning pool remains; the filter cloth bypasses the lower part of the guide wheel at the bottom of the pool and the upper part of the outer guide wheel respectively during the cleaning process, and the cleaned filter cloth returns to the onto the drive roller.

Further, a downward pressure guide wheel is installed in the middle of the upper part of the chemical residue cleaning tank, and the guide wheel is located under the nozzle, and the downward pressure guide wheel can make the filter cloth passing through its lower part present a "V" shape, which is convenient for the convergence of the spray, so that The spray sprayed on the filter cloth flows back into the chemical residue cleaning tank.

Further, a scraper is installed on the left side wall of the primary cleaning tank, and there is a receiving tank under the scraper. The scraper is used to scrape off a large amount of slurry remaining on the filter cloth before it enters the primary cleaning tank, so as to prevent the slurry from entering the primary cleaning tank and making the water turbid.

Further, a cleaning brush is installed in the primary cleaning tank, and the filter cloth entering the cleaning tank passes through the cleaning brush. The cleaning brush is used to clean the residue on the filter cloth.

Using this belt filter, in addition to cleaning the residual slurry on the filter cloth, it can also decompose the residual chemical particles in the filter holes on the filter cloth to prevent these particles from clogging the filter holes. Before the filter cloth enters the cleaning tank, the scraper can initially clean the residual slurry on the filter cloth to prevent too much residue from entering the cleaning tank, which can increase the number of times the cleaning solution is used. In addition, the squeeze wheel can crush the cleaned filter cloth to remove the water on the filter cloth, which is beneficial to maintain the filter performance of the filter cloth.

Fig. 1 is a schematic diagram of the planar structure of the utility model.

In the figure, frame 1, transmission roller 2, filter cloth 3, primary cleaning tank 6, chemical residue cleaning tank 7, secondary cleaning tank 8, extrusion wheel 9, scraper 10, receiving tank 11, cleaning brush 12, Guide wheel 13 at the bottom of the pool, spray pipe 14, material pump 15, guide wheel 16 outside the pool, and press guide wheel 17.

Detailed ways

The following are the preferred implementation modes of the present utility model, but the protection scope of the present utility model is not limited thereby.

As shown in the figure, a three-wash belt filter includes a frame 1, a transmission roller 2, a filter cloth 3, a primary cleaning pool 6, a chemical residue cleaning pool 7, a secondary cleaning pool 8, a squeeze wheel 9, Scraper 10, material receiving tank 11, cleaning brush 12, pool bottom guide wheel 13, nozzle 14, pumping pump 15, pool outer guide wheel 16, downward pressure guide wheel 17; it is characterized in that the bottom of the frame 1 From right to left, the initial cleaning tank 6, the chemical residue cleaning tank 7 and the secondary cleaning tank 8 are placed successively. In the primary cleaning tank 6 and the secondary cleaning tank 8, guide wheels 13 at the bottom of the pool are installed, and in the chemical residual cleaning tank 7 The upper part is equipped with two guide wheels 16 outside the pool; there is a pump 15 in the chemical residue cleaning pool 7, and the pump 15 is connected to the spray pipe 14 above the chemical residue cleaning pool 7 through a water pipe; the two ends of the upper part of the frame 1 The transmission roller 2 is installed, and the filter cloth 3 is laid on the transmission roller 2; the filter cloth 3 respectively bypasses the lower side of the pool bottom guide wheel 13 and the upper side of the pool outer guide wheel 16 during the cleaning process, and is cleaned The filter cloth 3 returns to the drive roller 2 after being squeezed by the squeeze wheel 9, and the squeeze wheel 9 can squeeze out the moisture on the cleaned filter cloth 3, increasing the filtering effect of the filter cloth 3.

Further, a downward pressure guide wheel 17 is installed in the middle of the upper part of the chemical residue cleaning pool 7, and the guide wheel is located below the nozzle 14, and the downward pressure guide wheel 17 can make the filter cloth 3 passing through its lower side present a "V" shape, When the nozzle 14 sprays the chemical reagent to the filter cloth 3, the chemical reagent will decompose the chemical residual particles on the filter cloth 3, because the filter cloth 3 here presents a "V" shape, the sprayed reagent can be gathered and re- Flow into the chemical residue cleaning pool 7.

Further, a scraper 10 is installed on the left side wall of the primary cleaning tank 6 , and there is a receiving tank 11 under the scraper 10 . Since there is slurry residue on the filter cloth 3 that has just filtered the slurry, before the filter cloth 3 enters the initial cleaning tank 6, the scraper 10 scrapes off a large amount of slurry remaining on the filter cloth 3 to prevent the slurry from entering the primary cleaning tank 6 and make the water body turbid.

Further, the primary cleaning tank 6 is equipped with a cleaning brush 12 , and the filter cloth 3 entering the primary cleaning tank 6 passes through the cleaning brush 12 . The cleaning brush 12 is used to clean the residue on the filter cloth 3, and can clean a large amount of residue on the filter cloth 3.

The utility model designs a three-wash belt filter. The belt filter is provided with three cleaning pools. In addition to cleaning the residual slurry on the filter cloth, it also cleans the residual chemical particles in the filter holes on the filter cloth. Decompose and prevent these particles from clogging the filter pores. Before the filter cloth enters the cleaning tank, the scraper can initially clean the residual slurry on the filter cloth to prevent too much residue from entering the cleaning tank, which can increase the number of times the cleaning solution is used. In addition, the squeeze wheel can crush the cleaned filter cloth to remove the water on the filter cloth, which is beneficial to maintain the filter performance of the filter cloth. The structural design of the utility model uses three cleaning pools to effectively clean up residues on the filter cloth and maintain the filter performance of the filter cloth.
