Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to a sewage treatment device for chemical production. Background Art

[0002] With the continuous development of society, people pay more and more attention to environmental pollution, especially the water pollution caused by the chemical industry. These chemical wastewaters often contain a large amount of heavy metal ions and other harmful substances. If these wastewaters are discharged directly, it will cause water pollution. Therefore, chemical wastewater needs to be treated before discharge to remove toxic and harmful substances. In real life, when treating chemical wastewater, flocculants are usually added to the treatment tank to make heavy metals and suspended matter flocculate and precipitate, so that the precipitation is separated and removed. However, most treatment tanks cannot remove the sediment in the treatment tank when removing the sediment. As the sediment accumulates, it is easy to enter the drain pipe and be discharged together with the treated water, thus affecting subsequent treatment.

[0003] A Chinese patent document (application publication number CN213537505U) discloses a sewage treatment device for chemical production, which includes a device body, wherein the device body includes a treatment box, a treatment box is fixedly installed on one side of the treatment box, a water pipe is fixedly connected to one side of the bottom end of the treatment box, one end of the water pipe extends to the interior of the treatment box, a reverse osmosis membrane is fixedly installed inside the treatment box, and a stirring mechanism is fixedly installed inside the treatment box.

[0004] It can be seen that the patent document cited above also has the same problem. After flocculation and sedimentation, the sediment is discharged through the sewage outlet in the middle of the bottom of the treatment box. This method cannot completely discharge the sediment on the side of the bottom of the treatment box. As the sediment accumulates, it is easy to enter the drain pipe and be discharged outward together with the treated water, thus affecting subsequent treatment. Summary of the invention

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The sewage treatment device for chemical production benefits from the design of the motor, connecting rod, connecting frame and fixed component. When the motor works, it drives the connecting frame to move upward through the connecting rod until the connecting frame moves out of the treatment box, and then the fixed component is opened and the fixed frame is pulled outward until the fixed frame moves out of the connecting frame. In this way, the flocculated sediment can be discharged cleanly to avoid sediment accumulation and discharge with the treated water, so as not to affect subsequent treatment. After the fixed frame is installed and reset, water is passed into the treatment box and flocculant is added. At this time, the motor works to drive the connecting frame to move downward through the connecting rod. The connecting frame can squeeze the sewage and make the sewage flow upward through the filter net, so that the sewage can be stirred and fully mixed with the flocculant.
