Technical Field

[0001] The invention relates to a device, in particular to a coal-containing wastewater treatment device, belonging to the technical field of industrial wastewater treatment. Background Art

[0002] Coal dust, coal particles and other substances in coal-containing wastewater will pollute the water quality. In traditional wastewater treatment processes, if coal removal is not performed, these coal dust and coal particles will greatly affect the removal of difficult-to-degrade organic matter and other pollutants, increase the difficulty of wastewater treatment, and make the treated water quality unable to meet the emission standards. Therefore, coal removal treatment must be carried out for coal-containing wastewater.

[0003] Existing coal-containing wastewater treatment equipment generally removes coal slag from wastewater through sedimentation, filtration, flotation, etc. to improve subsequent treatment efficiency. However, in existing equipment, after the coal slag is separated from the wastewater, the equipment must be stopped for coal slag collection before the coal slag can be cleaned, which affects work efficiency.

[0029] The implementation principle of the coal-containing wastewater treatment device of the present invention is:

[0030] The water inlet is connected to a coal-containing wastewater output device to introduce the coal-containing wastewater into the cavity of the box body. The coal-containing wastewater continuously enters the cavity, so that the coal-containing wastewater continuously passes through the filter barrel. The filter barrel filters the coal-containing wastewater, so that the coal slag continuously accumulates on the surface of the filter barrel to form a coal slag cake. When a certain amount of the coal slag cake is accumulated, the coal slag cake will block the filter channel. At this time, the motor needs to be started to make the filter barrel rotate with the power output of the motor. During the rotation, the scraper will scrape the surface of the filter barrel, thereby scraping and gathering the coal slag cake attached to the surface of the filter barrel. As the coal slag continues to gather and accumulate, the coal slag pushes the baffle into the collection box. The scraper and the filter barrel scraping part are pointed rubber strips. After the coal slag cake on the surface of the filter barrel is cleaned, the electric push rod is started to drive the collection rod to move downward. The end is located in the limit groove, and the limit groove is connected to the top of the collecting box, so the collecting rod directly enters the collecting box downward, and the collecting rod pushes the coal slag inside the collecting box downward, so that the coal slag enters the interior of the box body with the collecting rod. A baffle is provided on the top of the box body to allow the collecting rod and the coal slag to pass through, and the collecting rod moves upward, and a protrusion is provided at the bottom of the collecting rod and a rubber sheet is provided on the protrusion. At this time, the protrusion abuts against the baffle, and the baffle is composed of a rubber sheet, so that the protrusion seals the baffle. At this time, a sealed independent chamber is formed in the box body, and the coal slag collecting port is opened to collect the coal slag in the box body. After the coal slag is collected, continue to move the electric push rod back to its original state. During the above operation, the coal-containing wastewater is still continuously filtered, thereby achieving the effect of not having to stop filtering the coal-containing wastewater during the coal slag collection process.

The above examples are only intended to help understand the method and core concept of the present invention.
