Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater filtration device for environmental pollution control. Background Technology

[0002] Environmental pollution control refers to a series of comprehensive activities that use legal, economic, technological, administrative, and educational means to prevent, control, reduce, and remediate existing environmental pollution such as water, air, soil, noise, solid waste, and radioactivity, in order to improve environmental quality, ensure ecological security, and protect human health. Wastewater treatment requires the filtration and purification of wastewater.

[0003] However, in existing technologies, the filter plates of most filtration devices are fixed, and disassembly and assembly are cumbersome when cleaning or maintenance is required, which greatly reduces the cleaning and maintenance effect and thus reduces the efficiency of sewage filtration. Moreover, it is not convenient to adjust the extraction of sewage after sedimentation according to the water level, which reduces the extraction effect of sewage after sedimentation and reduces the efficiency of subsequent sewage treatment. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the filter plates of most filter devices are fixed, making disassembly and assembly cumbersome when cleaning or maintaining them, which greatly reduces the cleaning and maintenance effect and thus reduces the efficiency of sewage filtration. Furthermore, it is not convenient to adjust the extraction of settled sewage according to the water level, which reduces the extraction effect of settled sewage and the efficiency of subsequent sewage treatment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wastewater filtration device for environmental pollution control, comprising: a housing, wherein two partition plates are fixedly installed inside the housing, the two partition plates dividing the housing into a filtration zone, a sedimentation zone, and a purification zone, and further comprising:

[0006] A filter assembly is disposed inside the housing near the filter zone, and the filter assembly includes:

[0007] Two card slots are both located at the upper end of opposite sides inside the filter area, and a card plate is movably installed inside the card slots;

[0008] The first filter screen is fixedly installed on the upper end of the opposite sides of the two plates;

[0009] An adjustment component is disposed on one side of the outer surface of the sedimentation zone.

[0010] Preferably, the filtering component further includes:

[0011] The second filter screen is fixedly installed at the lower end of the opposite sides of the two plates;

[0012] The diameter of the filter holes in the second filter screen is smaller than that in the first filter screen.

[0014] Two limiting pins are movably disposed on the outer surface of the housing near the slot. A spring is fixedly disposed on the outer surface of the limiting pin, and the other end of the spring is connected to the housing.

[0015] The technical effect of adopting the above-mentioned further solution is that the sewage is discharged to the upper end of the filtration zone through the conveying pipe, and the sewage flows onto the first filter screen and the second filter screen. The double-layer filtration can better intercept particulate impurities in the sewage. The filtered sewage flows to multiple outlet pipes through the guide plate. The multiple outlet pipes transport the sewage to the interior of the sedimentation zone for sedimentation treatment.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0046] Example 1, as Figure 1-4 As shown, this utility model provides a wastewater filtration device for environmental pollution control, including: a housing 1, a filtration assembly, and an adjustment assembly;

[0047] The filter assembly includes: slots 114 are provided at the upper ends of opposite surfaces inside the filter zone 102, and a card plate 105 is movably embedded inside the slots 114. A first filter screen 104 and a second filter screen 116 are respectively fixedly installed at the upper and lower ends of opposite surfaces of the two card plates 105.

[0048] The clamping plate 105 can improve the stability of the first filter plate 104 and the second filter plate 116, making them more stably embedded in the filter area 102.

[0049] Both card plates 105 have limit holes 1051 on the upper part of their back sides. Limit pins 123 are movably embedded on the outer surface of the box body 1 near the card slot 114. A spring 124 is fixedly connected to the outer surface of the limit pin 123, and the other end of the spring 124 is fixedly connected to the outer surface of the box body 1.

[0050] Among them, the limiting pin 123 is embedded in the limiting hole 1051 under the elastic force of the spring 124, which can position the card plate 105 and make it more stably embedded in the card slot 114.

[0051] A guide plate 115 is fixedly installed at the lower end of the interior of the filter zone 102;

[0052] Another partition plate 101 has multiple water outlet pipes 117 fixedly installed at its lower end, and a one-way valve 118 is fixedly installed on the outer surface of the water outlet pipes 117.

[0053] In this embodiment, the one-way valve 118 can prevent the filtered wastewater from flowing back into the filtration zone 102, allowing the filtered wastewater to flow into the sedimentation zone 103 for sedimentation treatment.

[0054] Example 2, as Figure 1-4 As shown, the adjustment assembly includes: a pump body 106 is fixedly installed at the top center of a partition plate 101, and a U-shaped tube 108 is fixedly installed at the output end of the pump body 106. One end of the U-shaped tube 108 is embedded in the sedimentation zone 103, and the other end is embedded in the purification zone 113.

[0055] Among them, the sewage inside the sedimentation zone 103 can be pumped into the purification zone 113 for purification treatment through the pump body 106, thereby improving the water quality;

[0056] A waterproof box 107 is fixedly installed on the side of the partition plate 101 near the pump body 106. An electric push rod 122 is fixedly installed inside the waterproof box 107. A connecting block 111 is fixedly installed at the output end of the electric push rod 122. A telescopic tube 109 is fixedly installed at one end of the U-shaped tube 108. A baffle net 110 is fixedly installed at the other end of the telescopic tube 109. The connecting block 111 is fixedly installed at the lower end of the telescopic tube 109.

[0057] Among them, the electric push rod 122 can drive the telescopic pipe 109 to extend and retract through the connecting block 111, so that the telescopic pipe 109 can be adjusted according to the water level, and the settled sewage can be extracted better.

[0058] A connecting rod 119 is movably embedded in the center of the sedimentation zone 103, and multiple stirring blades 120 are fixedly installed on the outer surface of the connecting rod 119.

[0060] A sealing cover 112 is movably installed on the top outer surface of the box 1 near the purification zone 113, and a drain pipe 121 is fixedly installed on the lower end of the outer surface of the box 1 on the side near the purification zone 113.

[0061] In this embodiment, the drive motor 2 drives multiple stirring blades 120 to stir the filtered sewage through the connecting rod 119. At the same time, flocculant is added to make the flocculant and sewage more evenly mixed. The flocculant can aggregate the tiny, dispersed, and difficult-to-settle suspended particles and colloidal substances in the sewage into larger flocs, thereby improving the sewage sedimentation effect.

[0062] Working principle: Wastewater is discharged to the upper end of the filtration zone 102 through the conveying pipe. The wastewater flows onto the first filter screen 104 and the second filter screen 116. The double-layer filtration can better intercept particulate impurities in the wastewater. The filtered wastewater flows to multiple outlet pipes 117 through the guide plate 115. The multiple outlet pipes 117 transport the wastewater to the interior of the sedimentation zone 103 for sedimentation treatment. Pull the limiting pin 123 to move out of the limiting hole 1051. Then, the first filter screen 104 and the second filter screen 116 are removed from the interior of the filtration zone 102 through the clamping plate 105. They can then be cleaned and maintained. Disassembly and assembly are relatively quick, which greatly improves the cleaning effect of the first filter screen 104 and the second filter screen 116.

[0063] The electric push rod 122 is activated, which drives the telescopic pipe 109 to move up and down through the connecting block 111. The adjustment is made according to the water level of the sewage after sedimentation in the sedimentation zone 103, making it easier and faster to extract the sedimented sewage into the purification zone 113 for purification. A baffle net 110 is fixedly installed at the bottom of the telescopic pipe 109. The baffle net 110 can block the sedimented flocculent matter and prevent it from entering the telescopic pipe 109 during extraction, thus affecting the sewage purification effect. The purification zone 113 can be filled with some water purification materials, such as activated carbon. The sealing cover 112 can prevent impurities from entering.

[0064] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
