In the process of treating and reusing wastewater, a wastewater treatment device with the function of wastewater reuse needs to be used.

[0003] A wastewater reuse treatment tank is disclosed in a Chinese patent document with the publication number CN217323660U, which includes a tank body and a wastewater inlet pipe. A drain pipe is installed at the bottom of the tank body. Foam agent is introduced into the tank body through the drain pipe to wrap the suspended particles in the wastewater and make them float. The inside of the tank body is divided into a filtering layer and a flotation layer by a filtering diversion plate. The wastewater inlet pipe is connected to the filtering layer, and the drain pipe is installed in the flotation layer. A plurality of filtering diversion plates are provided and are inclined, so that the opening size surrounded by the tops of several filtering diversion plates is smaller than the opening size surrounded by the bottoms of the filtering diversion plates. A suction mechanism for sucking away suspended particles is installed in the opening surrounded by the tops. Large particle impurities can be filtered into the flotation layer, and the foam that floats by wrapping the suspended particles can be introduced to the position of the suction mechanism by using the diversion function of the filtering diversion plate.

[0004] The disadvantages of the above disclosed solution are as follows: Although the filtering diversion plate can filter large particle impurities that cannot float, as the large particle impurities accumulate on the surface of the filtering diversion plate, it causes blockage to the filtering diversion plate, resulting in a reduction in the filtering efficiency of the filtering and guiding plate, thereby affecting the treatment efficiency of wastewater.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 - 5, the present utility model provides a technical solution: a wastewater treatment device with a wastewater reuse function, including a tank body 1. A filter plate 3 is fixedly arranged inside the tank body 1. The filter plate 3 is in a frustum shape with openings at both the top and bottom. At the upper opening of the filter plate 3, there is a sand pumping assembly for sucking suspended particles. The sand pumping assembly includes a sand pump 11, which is fixedly arranged in the opening above the filter plate 3. The input port of the sand pump 11 is connected to a hose 10, and the hose 10 is a corrugated hose. The other end of the hose 10 is connected to a multi-way valve 9. A plurality of sand pumping ports are arranged on the outer circumference of the multi-way valve 9, which can suck away the suspended particles over a large area. The hose 10 enables the multi-way valve 9 to move up and down.

[0025] A float 8 is fixedly arranged at the bottom of the multi-way valve 9. The float 8 can float the multi-way valve 9, making the multi-way valve 9 float on the water surface. When sucking the suspended particles on the water surface, a large amount of wastewater will not be sucked away, thus reducing the waste of water. The bottom of the float 8 is in an irregular arc shape, which avoids the bottom of the float 8 from hindering the floating of the suspended particles out of the water surface, so as to suck the suspended particles more thoroughly.

[0026] A collection box 13 is fixedly arranged on the outer side of the tank body 1. The output port of the sand pump 11 is connected to a conduit 12, and the conduit 12 is connected to the interior of the collection box 13. The suspended particles are pumped into the collection box 13 by the sand pump 11, which is convenient for centralized treatment of the suspended particles.

[0027] A toothed ring 14 is rotatably sleeved on the top of the filter plate 3. A rotating assembly for driving the toothed ring 14 to rotate is arranged on the tank body 1. The rotating assembly includes a motor 16. A fixed plate 17 is fixedly arranged inside the tank body 1. The motor 16 is fixedly arranged on the fixed plate 17. The output end of the motor 16 passes downward through the fixed plate 17 and is fixedly sleeved with a gear 15, and the gear 15 meshes with the toothed ring 14. A scraper 22 is fixedly arranged at the bottom of the toothed ring 14, and the scraper 22 is attached to the outer surface of the filter plate 3. The scraper 22 cleans the impurities filtered on the outer surface of the filter plate 3.

[0028] A waste discharge hole 19 is formed in the tank body 1. The waste discharge hole 19 is flush with the bottom of the outer surface of the filter plate 3 and is inclined for easy discharge of impurities. A collection box 21 is arranged on the outer side of the tank body 1, and the collection box 21 is used to collect the impurities discharged from the waste discharge hole 19. A slider 18 is slidably arranged through the tank body 1. A spring 20 is fixedly arranged between the slider 18 and the collection box 13. A stop block is integrally formed at the bottom of the slider 18, and the spring 20 pushes the stop block through the slider 18 to block the waste discharge hole 19 to prevent wastewater from being discharged from the waste discharge hole 19. A push block 23 is fixedly arranged at the bottom of the scraper 22. When the scraper 22 cleans the surface of the filter plate 3, it drives the push block 23 to push the slider 18 to move outward.

[0029] One side of the slider 18 located inside the tank body 1 is an arc surface, and one side of the push block 23 close to the tank body 1 is an arc surface. The arc surface of the push block 23 is in sliding fit with the arc surface of the slider 18, and the push block 23 pushes the slider 18 to move outward, so as to release the blockage of the impurity discharge hole 19 by the stop block, facilitating the discharge of impurities. And the width of the slider 18 is greater than the aperture of the impurity discharge hole 19, ensuring that after the push block 23 contacts the slider 18 first, the slider 18 drives the stop block to contact and block the impurity discharge hole 19, thereby preventing the stop block from hindering the discharge of impurities.

[0030] A medicine injection assembly for injecting medicine into the tank body 1 is arranged on the outer side of the tank body 1. The medicine injection assembly includes a medicine tank 5, the medicine tank 5 is arranged on one side of the tank body 1, a liquid extraction pump 6 is fixedly arranged on the medicine tank 5, and the input port of the liquid extraction pump 6 is communicated with the inside of the medicine tank 5 through a liquid inlet pipe. The output port of the liquid extraction pump 6 is communicated with a medicine discharge pipe 7, the medicine discharge pipe 7 passes through the tank body 1 and extends to the inside of the tank body 1, the medicine discharge pipe 7 is laid at the bottom inside the tank body 1, and the part of the medicine discharge pipe 7 located inside the tank body 1 is evenly provided with medicine discharge holes.

[0031] A hydrophobic film 4 is fixedly arranged on the inner side of the filter plate 3, and the hydrophobic film 4 can prevent the bubbles formed by the medicine from adhering to the surface of the filter plate 3, thereby affecting the drainage function of the filter plate 3.

[0032] A water inlet pipe 2 communicated with the inside thereof is arranged at the top of the tank body 1, and the water inlet pipe 2 is located above the filter plate 3. A drain pipe 24 communicated with the inside thereof is arranged at the bottom of the tank body 1, and a control valve is arranged on the drain pipe 24.

[0033] The working principle of a wastewater treatment device with a wastewater reuse function provided by the present utility model is as follows:

[0034] During use, wastewater is made to enter the tank body 1 through the water inlet pipe 2, and the filter plate 3 filters out large particles that cannot float in the wastewater. After the wastewater is filtered, it enters the lower part of the filter plate 3, and then the liquid extraction pump 6 is started to pump the foam medicine in the medicine tank 5 into the tank body 1 through the medicine discharge pipe 7. The foam medicine wraps the suspended particles in the wastewater and floats up, so that the suspended particles float on the surface of the water.

[0035] Start the sand extraction pump 11, and the sand extraction pump 11 sucks away the floating particles through the hose 10 and the multi-way valve 9, and sends the sucked particles into the collection box 13 through the conduit pipe!2.

[0036] When it is necessary to discharge the treated wastewater, the control valve on the drain pipe 24 is opened, and the treated wastewater is discharged through the drain pipe 24 for reuse.

[0037] When it is necessary to clean the impurities on the outer surface of the filter plate 3, the motor 16 is started, the motor 16 drives the gear 15 to rotate, the gear 15 drives the gear ring 14 to rotate, and the gear ring 14 drives the scraper 22 to rotate, so that the scraper 22 scrapes and cleans the impurities on the outer surface of the filter plate 3. Since the outer surface of the filter plate 3 is arranged at an angle, the impurities on the outer surface of the filter plate 3 will roll to the bottom of the filter plate 3 during the process of being scraped by the scraper 22.

[0038] The rotation of the scraper 22 simultaneously drives the push block 23 to rotate. During the rotation process, the push block 23 contacts the slider 18 and slides with the curved surface of the slider 18, pushing the slider 18 to move outward and compressing the spring 20. The slider 18 drives the block to move to release the obstruction of the impurity discharge hole 19, so that the scraper 22 drives the impurities on the outer surface of the filter plate 3 to be discharged into the collection box 21 through the impurity discharge hole 19. This prevents large impurities from accumulating on the filter plate 3 and causing blockage of the filter plate 3. After cleaning the impurities on the outer surface of the filter plate 3, the filtration efficiency of the filter plate 3 can be improved, thereby improving the wastewater treatment efficiency.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
