Description

Technical Field

[0001] The utility model relates to the technical field of groundwater treatment, and more specifically, to a groundwater pollution treatment device. Background Art

[0002] Groundwater pollution mainly refers to the phenomenon that human activities cause changes in the chemical composition, physical properties and biological characteristics of groundwater, resulting in a decline in quality. The strata below the surface are complex and the flow of groundwater is extremely slow. Therefore, groundwater pollution has the characteristics of slow process, difficult to detect and difficult to control. Groundwater pollution is the phenomenon that groundwater quality deteriorates due to human factors. The main causes of groundwater pollution are: direct discharge of industrial wastewater into the ground, intrusion of contaminated surface water into underground aquifers, etc.

[0003] For example, a groundwater pollution control device with a publication (announcement) number of CN212151836U includes a control device body, a purification box is fixedly connected to the right side of the control device body, a sleeve is fixedly connected to the inside of the purification box, a filter tube is connected to the inside of the sleeve, the rear end of the sleeve is connected to the back of the purification box, and a water inlet pipe is arranged on the top of the purification box. The utility model extracts groundwater and discharges it into the inside of the sleeve through the water inlet pipe. The groundwater flows inside the sleeve through its own fluidity and enters the interlayer between the purification box and the sleeve through the filtration of the filter tube, thereby completing the separation and filtration of sludge and groundwater, solving the problem that the existing water pollution control device does not have the effect of pre-filtering sludge, and a large amount of silt carried by the groundwater enters the water pollution control device and easily blocks the control pipeline, reducing the purification effect of the water pollution control device.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that the above device separates silt from groundwater through the filter tube. Long-term filtration of silt will cause the filter holes of the filter tube to be blocked by silt and impurities. As the silt accumulates on the filter tube, the filtering effect of the filter tube on groundwater gradually decreases. In addition, the filter tube is installed inside the box, which makes subsequent maintenance and cleaning more difficult. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a groundwater pollution control device, which has the advantage of self-cleaning filter.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a groundwater pollution control device, comprising a control device body and a pretreatment box, drive motors are fixedly installed on both sides of the top of the pretreatment box, a rotating shaft is provided at the bottom of the drive motor, an assembly disk is fixedly installed at the bottom of the rotating shaft, a plurality of slots are provided at the bottom of the assembly disk, brushes are fixedly installed inside the slots, and sewage pipes are fixedly installed on both sides of the pretreatment box.

[0007] As a preferred technical solution of the utility model, a liquid inlet pipe is fixedly installed on the top of the pretreatment box, a liquid collecting hopper is fixedly installed on the top of the liquid inlet pipe, and guide blocks are fixedly installed on both sides of the inner wall of the liquid inlet pipe.

[0008] As a preferred technical solution of the utility model, a transverse groove is provided in the middle of the front side of the pre-treatment box, and a filter is movably installed inside the transverse groove.

[0009] As a preferred technical solution of the utility model, an outer frame is fixedly installed on the outside of the filter, and a plurality of strong magnetic blocks are fixedly installed on the back of the outer frame.

[0012] As a preferred technical solution of the utility model, a discharge pipe is fixedly installed at the bottom of the pretreatment box, and the discharge pipe is threadedly connected to the treatment device body.

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

[0014] 1. The utility model realizes the self-cleaning function of the filter through the structural design of the pretreatment box, the drive motor, the rotating shaft, the assembly disk, the slot and the brush, and through the mutual cooperation between the structures, thereby reducing the adhesion of sludge or granular impurities on the filtering surface of the filter, thereby reducing the burden of the filter in subsequent filtration, ensuring the processing efficiency of the filter, avoiding manual cleaning and the frequency of filter replacement, and thus reducing maintenance costs.

[0015] 2.
