Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an industrial wastewater treatment and mud removal device. Background Art

[0002] Industrial wastewater desludging is an important part of the industrial wastewater treatment process. Its main purpose is to remove pollutants such as suspended solids in the wastewater. Filtration is one of the commonly used methods for industrial wastewater desludging. Its principle is to use porous media, such as filter cloth, filter paper, filter screen, etc., to intercept suspended matter in the wastewater, so that water passes through the medium while the suspended matter is retained on the medium, thereby achieving mud and water separation.

[0003] Publication No. CN218709544U discloses an industrial wastewater treatment mud removal device, which includes a box body, a rotating mechanism and a mud removal mechanism. Two groups of third connecting rods are fixedly installed on both sides of the box body and are distributed up and down. The rotating mechanism is arranged on the box body. Through the combined use of a motor, a rotating rod, a first connecting rod, a first scraper, a fan blade, a second connecting rod and a second scraper, the device can accelerate the mixing speed of mud and dust in sewage with a flocculant. After the mud and dust are mixed with the flocculant, the volume of the mud and dust becomes larger and is not easy to leak from the filter screen. The mud and dust can be better mixed with the flocculant through rotation. At the same time, the sludge is placed on the inner wall of the box body by hanging the inner wall of the box body. The mud removal mechanism is arranged on the box body, so that the device can collect the sludge more conveniently. By removing the installation cover, the inside of the device can be better cleaned.

[0004] The above-mentioned mud removal device has the following defects: the first scraper and the second scraper of the device are both fixedly installed, and it is difficult to ensure that there is no gap between them and the box body, so the mud scraping effect cannot be guaranteed. The device uses a threaded installation cover to install the filter screen. When a lot of sludge accumulates above the filter screen, the installation cover will be difficult to remove under the action of gravity.

[0005] In view of the above device defects, an industrial wastewater treatment and mud removal device is proposed. Utility Model Content

The two stirring paddles 303 stir the wastewater and the flocculant. The flocculant accelerates the sedimentation of sludge. The filter screen 109 filters the wastewater. The filtered wastewater is discharged from the water outlet of the lower tank body 105. The two scraping plates 306 clean the inner wall of the upper tank body 101 to prevent sludge from sticking to the wall;

[0037] When the filter screen 109 needs to be cleaned, the hydraulic cylinder 202 drives the lower tank body 105 to descend. Under the action of gravity, the connecting ring 108 descends synchronously with the lower tank body 105. At this time, the connecting ring 108 together with the filter screen 109 can be removed. After cleaning the filter screen 109 and resetting the device, the wastewater treatment operation can be continued.
