[0002] Wastewater treatment is to treat wastewater using physical, chemical and biological methods to purify wastewater, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. Domestic sewage refers to wastewater discharged by people in their daily life activities. This wastewater is mainly polluted by domestic waste and human excrement. The amount, composition and concentration of pollutants are related to people's living habits and water consumption. Domestic sewage generally does not contain toxic substances, but it has conditions suitable for the reproduction of microorganisms and contains a large number of bacteria and pathogens. From a hygienic point of view, it has certain hazards. Wastewater generated in life or production needs to be treated before it can be discharged into the natural environment.

[0003] Domestic or industrial wastewater is often discharged together with solid waste from domestic or industrial use. When treating wastewater, solid materials are easy to block the transportation and treatment pipeline. It is necessary to filter the solid waste first to filter out the solid waste, so as to facilitate the subsequent physical or biochemical treatment of the wastewater. Therefore, a wastewater treatment device with a filtering structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-7 A wastewater treatment device with a filtering structure includes two treatment cylinders 1, which are connected by a connecting frame 2. The interior of the treatment cylinder 1 located at the bottom is in an inverted cone shape, and the bottom wall of the treatment cylinder 1 is connected to a transportation pipeline. The specific structure is not described in detail in this scheme, and reference can be made to the prior art.

[0027] A fixing frame 8 is installed on the processing cylinder 1. A rotating shaft 10 and a connecting block 11 are provided on the fixing frame 8 through an upper motor 9. Movable grooves 15 are provided on the outer walls on both sides of the connecting block 11. A sliding rod 16 is provided in the movable groove 15. A connecting rod 17 is provided on the sliding rod 16 through a sliding sleeve of a reset mechanism. A connecting ring 3 is rotatably installed on the connecting rod 17. The connecting ring 3 is connected to the processing cylinder 1 through a sealing mechanism. A filter screen 4 is provided on the connecting ring 3 through an installation mechanism. A cam 13 is provided on the fixing frame 8 through a lower motor 14. The cam 13 is connected to the connecting rod 17 through a contact mechanism.

[0028] The reset mechanism includes a reset spring 18 sleeved on the outside of the slide rod 16, and the two ends of the reset spring 18 are elastically connected to the outer wall of the connecting rod 17 and the inner wall of the movable groove 15 respectively. After the connecting rod 17 and other components slide down on the slide rod 16 and compress the reset spring 18, the upward reset is achieved by relying on the elastic potential energy provided by the reset spring 18.

[0029] The sealing mechanism includes a sealing ring 7 arranged on the upper and lower end surfaces of the connecting ring 3. The surfaces of the two treatment cylinders 1 in contact with the connecting ring 3 are both provided with annular sealing grooves corresponding to the sealing ring 7. When the connecting ring 3 is between the two treatment cylinders 1, the sealing ring 7 is in the annular sealing groove, which can ensure the sealing performance of the wastewater treatment device.

[0030] The mounting mechanism includes a plurality of mounting plates 5 welded on the filter screen 4, and the mounting plates 5 are connected to the connecting ring 3 via a first bolt 6. The mounting plates 5 and the first bolt 6 are used to facilitate disassembly and assembly of the filter screen 4 relative to the connecting ring 3. The mounting plate 5 in the treatment cylinder 1 is located below the filter screen 4, so as to prevent the impurities filtered and intercepted by the upper end surface of the filter screen 4 from contaminating the first bolt 6 and the mounting plate 5.

[0031] The contact mechanism includes a contact plate 12 fixedly mounted on a coupling rod 17. The contact plate 12 is provided with an extrusion groove corresponding to the cam 13. The cam 13 can cooperate with the extrusion groove to reciprocately press the contact plate 12, thereby realizing the reciprocating pressing operation of the coupling ring 3 and other components.

[0032] A second bolt is installed on the contact plate 12, and two threaded connection grooves corresponding to the second bolt are provided on the outer wall of the connecting ring 3. After the connecting ring 3 rotates 180 degrees to complete the flip, the second bolt enters another threaded connection groove to maintain the current state of the connecting ring 3.

[0033] The distance between the two treatment cylinders 1 is equal to the thickness of the connecting ring 3 , and the inner diameters of the two treatment cylinders 1 are equal to the outer diameter of the filter 4 . The above design ensures better connection between the filter 4 and other components and the treatment cylinder 1 .

[0034] The two connecting rings 3 are circumferentially evenly spaced relative to the rotating shaft 10. After the upper motor 9 drives the rotating shaft 10 to rotate 180 degrees, the two connecting rings 3 and the remaining equipment components arranged on the connecting rings 3 can be rotated and replaced. The multiple mounting plates 5 are circumferentially evenly spaced relative to the filter screen 4. The circumferential evenly spaced distribution ensures that the connection force between the filter screen 4 and the connecting ring 3 is more balanced.

[0035] When the utility model is used, the waste water is filtered through the two treatment cylinders 1 and the filter screen 4. The filter screen 4 can intercept impurities. The impurities are located on the upper end surface of the filter screen 4 and in the connecting ring 3. When the impurities accumulate too much and affect the filtering operation of the filter screen 4, the passage of the waste water is suspended, and the upper motor 9 is immediately started. The upper motor 9 drives the rotating shaft 10 and the connecting block 11 to rotate. The connecting block 11 cooperates with the connecting rod 17 and other components to drive the two connecting rings 3 and the filter screen 4 to rotate. After rotating 180 degrees, the replacement is completed, and the passage and filtering operation of the waste water can be performed again.

[0036] The connecting ring 3 and the filter screen 4 on the outside can be cleaned. First, unscrew the second bolt on the contact plate 12, then turn the connecting ring 3 and the filter screen 4 180 degrees, and then contact the second bolt to fix the connecting ring 3. At this time, some impurities fall directly, and a collecting device is set below to collect them. Then start the lower motor 14, and the lower motor 14 drives the cam 13 to rotate. The cam 13 will reciprocate and press down the connecting ring 3 and other components, and the connecting ring 3 and other components will be reset under the action of the reset spring 18, and the connecting rod 17 hits the inner wall of the movable groove 15. The vibration generated by the impact is finally transmitted to the filter screen 4, which can realize the shaking-off operation of the residual impurities on the filter screen 4.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
