Description

A waste water filter

technical field

The utility model relates to the technical field of waste water treatment, in particular to a waste water filtering device.

Background technique

At present, a large amount of waste water is produced in the process of papermaking in paper mills. Specifically, in the process of slag removal, pulp washing, and rinsing of raw materials, a large amount of waste water rich in wood fiber and other impurities will be produced. If these waste water are directly discharged, it will inevitably cause serious environmental pollution. There is often a large amount of pulp left in the pulp. If it is directly discharged, the wood fiber will be discharged in vain, which is a waste of resources. Therefore, several filter devices are usually installed in the paper mill to intercept and collect the solid waste in the wastewater. However, the existing wastewater filtration device has a slow filtration speed and low efficiency, and the pulp tends to block the screen holes during the filtration process, resulting in a slow filtration speed.

In view of the above-mentioned problems, the Chinese Patent Publication No. CN208065915U discloses a waste water filter device for pulp and paper production. A first bracket is installed at the bottom of the water tank, one side of the water pump is connected to an elbow, and one end of the elbow is connected to a joint, a clamping groove is arranged in the middle of the side wall of the joint, and the joint is connected to the filter box; one end of the filter box is provided with a water inlet, and the water inlet and the joint are mutually clamped , A cleaning port is set on the outer side wall of the filter box, two top grooves are set on the bottom side wall of the filter box, a collection box is installed between the two top grooves, a drop block is installed at the bottom of the collection box, a slide frame is set inside the filter box, and the slide frame is installed inside There are three filter plates, and one side of the sliding frame is provided with a drain groove, a second bracket is installed at the bottom of the filter box, two telescopic rods are installed on the top of the second bracket, an air pump is installed on the inner wall of the bottom of the two telescopic rods, and the tops of the two telescopic rods are respectively Snap into the top groove at the bottom of the filter box. The filter box is tilted by two telescopic rods. With the reciprocation of the two telescopic rods, one ascending and one descending operation is performed, so that the waste water inside the filter box can be continuously filtered back and forth, thereby improving the filtering effect. The constant swing makes the filter plate inside the filter box swing together, and the filter plate will not be blocked under the impact of waste water.

This solution solves the problems that the existing wastewater filtration device has a slow filtration speed and the sieve holes of the filter plate are easily blocked. However, during the filtration process, the pulp will accumulate at the filter plate, which directly leads to the gradual deterioration of the filtration effect. The filter plate must be manually adjusted. To clean up the pulp on it, the user's workload is large and it is inconvenient to use.
