[0015] Compared with the prior art, the above technical scheme of the present application has the following beneficial technical effects:

[0016] The sewage source is connected with the water control pipe on the processing cylinder one, the disinfectant water input source is connected with the conveying pipe two, the sewage enters the processing cylinder one, and then enters the telescopic cylinder through the hole one, so that the sewage is filtered in one stage through the filter plate on the lifting plate, the filtered sewage is subjected to two-stage adsorption treatment through the adsorption processing piece, and then the sewage is input into the processing cylinder two through the conveying pipe one for three-stage disinfection treatment, so that the multi-stage treatment of the sewage is completed.

[0020] In the process of lifting the lifting plate to the top end, the conical block is pushed upward by the clamping block, so that the linkage frame moves upward, and then the mounting frame moves upward, but because of the elasticity of the elastic member seven, when the clamping block moves to a certain degree, the conical block and the clamping block are staggered, so that the mounting frame vibrates rapidly, and when the telescopic barrel drives the clamping block to descend, the clamping block still pulls the conical block downward for a distance, and then the clamping block is staggered, so as to realize the vibration of the filter box, and avoid the filter box from being blocked.

DETAILED DESCRIPTION

[0029] In example one, as shown, the present application proposes a double-cylinder sewage treatment device, which comprises a support seat 1, a processing cylinder one 2, a primary processing mechanism, a secondary processing mechanism, a collection mechanism, a processing cylinder two 5 and an adsorption processing piece 22. Figures 1-7

[0030] ​​​The primary treatment mechanism is installed on the treatment cylinder 2, sewage is filtered by the filtering mechanism and adsorbed by the adsorption treatment piece 22 to enter the treatment cylinder 2 for disinfection treatment, and the multi-stage treatment of sewage is completed; the secondary treatment mechanism is installed in the treatment cylinder 2 for secondary treatment of sewage; the collecting mechanism is installed outside the treatment cylinder 2 and is used for collecting sewage debris; the primary treatment mechanism comprises a filtering assembly, a sealing assembly, a pushing assembly, a fixing assembly and a lifting plate 8; the filtering assembly is installed on the treatment cylinder 2, the lifting plate 8 is installed on the moving end of the filtering assembly, and the filtering plate 11 is installed on the lifting plate 8; the sealing assembly is installed at the bottom of the filtering assembly and seals the filtering plate 11 after the filtering assembly rises; the pushing assembly is installed in the filtering assembly; the fixing assembly is installed at the bottom of the inner cavity of the treatment cylinder 2, and the pushing assembly is pulled by the fixing assembly to accumulate elastic force after the sealing assembly descends; after the filtering assembly filters the sewage, the debris is accumulated in the filtering assembly, and the pushing assembly is pulled by the fixing assembly after descending, and the collected debris is transported into the collecting mechanism when the pushing assembly rises to the top end of the treatment cylinder 2; the adsorption treatment piece 22 is an activated carbon layer.

[0031] The filtering assembly comprises a driving device 7, an elastic piece 9 and a telescopic cylinder 10; the driving device 7 is installed on the treatment cylinder 2, and the output shaft of the driving device 7 is connected with the lifting plate 8; the two ends of the elastic piece 9 are respectively connected with the telescopic cylinder 10 and the lifting plate 8; the telescopic cylinder 10 is connected with the lifting plate 8; the telescopic cylinder 10 is provided with a hole 26 and a hole 27.

[0032] The driving device 7 is started to drive the lifting plate 8 to ascend and descend in the inner cavity of the treatment cylinder 2, so that the sewage in the inner cavity of the treatment cylinder 2 is filtered through the filtering plate 11.

[0033] The sealing assembly comprises a pulling rope 12, an elastic piece 13 and a blocking plate 14; the two ends of the pulling rope 12 are respectively connected with the top of the telescopic cylinder 10 and the blocking plate 14; the bottom of the side close to the pulling rope 12 of the lifting plate 8 is a vertical plate, the lifting plate 8 is L-shaped, and the two ends of the elastic piece 13 are respectively connected with the vertical plate of the bottom of the lifting plate 8 and the blocking plate 14; when the telescopic cylinder 10 is contracted, the elastic piece 13 releases the elasticity to drive the blocking plate 14 to block the filtering plate 11.

[0034] In the initial state, the telescopic cylinder 10 and the elastic piece 9 are in the longest elongated state, at this time, the distance between the top end of the telescopic cylinder 10 and the lifting plate 8 is the longest, so that the pulling rope 12 is pulled by the top end of the telescopic cylinder 10, thereby pulling the blocking plate 14 to the elastic piece 13, so that the elastic piece 13 is compressed, at this time, the blocking plate 14 and the filtering plate 11 are staggered, and at this time, the sewage passes through the filtering plate 11 for filtration.

[0035] The pushing assembly includes an elastic element 15, a pushing plate 16, a pull rope 17, and a locking connector 18; the two ends of the elastic element 15 are respectively connected to the telescopic cylinder 10 and the pushing plate 16; the two ends of the pull rope 17 are respectively connected to the pushing plate 16 and the locking connector 18; when the lifting plate 8 descends to the bottom, the locking connector 18 is clamped by the fixing assembly.

[0036] After the lifting plate 8 rises to its highest point, the elastic element 3 15 drives the push plate 16 to move toward the hole 27. At this time, the elastic element 3 15 extends to its longest state. Due to the flatness of the top of the locking connector 18, the plane of the top of the locking connector 18 fits with the bottom of the lifting plate 8, thus limiting the locking connector 18. Therefore, during the descent of the lifting plate 8, the locking connector 18 will not tilt, and thus the locking connector 18 will not deviate during the descent of the lifting plate 8.

[0037] The fixing component includes a mounting part 23, an elastic element 24, and a triangular block 25; the mounting part 23 is installed inside the processing cylinder 2 and above the adsorption processing element 22; the two ends of the elastic element 24 are respectively connected to the mounting part 23 and the triangular block 25; when the snap-fit ​​connector 18 is inserted into the mounting part 23, it is snapped into place by the triangular block 25.

[0038] As the lifting plate 8 lowers the connector 18, the bottom end of the connector 18 passes between the two triangular blocks 25 and is locked and limited by the two triangular blocks 25.

[0039] Example 2, as Figures 1-4 As shown, the present invention proposes a dual-cylinder sewage treatment device. Compared with Embodiment 1, the collection mechanism of this embodiment includes a conveying pipe 28, an installation chamber 29, a one-way pipe 30, and a collection assembly. The installation chamber 29 is installed outside the treatment cylinder 2. The inlet end of the conveying pipe 28 is connected to the treatment cylinder 2, and its outlet end is connected to the installation chamber 29. The inlet end of the one-way pipe 30 is connected to the installation chamber 29, and its outlet end is connected to the inner cavity of the treatment cylinder 2, and the connection point is located above the adsorption treatment element 22.

[0040] When the top of the telescopic cylinder 10 rises to the top of the inner cavity of the processing cylinder 2, the hole 26 is aligned with the connection between the processing cylinder 2 and the water control pipe 3, and at this time the connection between the processing cylinder 2 and the water control pipe 3 is connected to the hole 26; while the hole 27 is aligned with the connection between the delivery pipe 28 and the processing cylinder 2, and at this time the connection between the processing cylinder 2 and the delivery pipe 28 is connected to the hole 27.

[0041] The collection components include an elastic element 31, a mounting frame 32, a filter box 33, and a vibration unit; the two ends of the elastic element 31 are respectively connected to the mounting chamber 29 and the mounting frame 32; a sliding groove is opened in the mounting frame 32, the filter box 33 is slidably connected in the sliding groove, and the vibration unit is mounted on the mounting frame 32.

[0042] Wastewater entering the inner cavity of installation chamber 29 is further filtered through filter box 33, so that the filtered wastewater enters the inner cavity of treatment cylinder 2 through one-way pipe 30. One-way pipe 30 consists of one-way valve and round pipe 1, which allows wastewater in the inner cavity of installation chamber 29 to enter the inner cavity of treatment cylinder 2 through one-way pipe 30, while wastewater in the inner cavity of treatment cylinder 2 cannot enter the inner cavity of installation chamber 29 through one-way pipe 30.

[0043] The vibration unit includes a linkage frame 34, a conical block 35, an elastic element 36, and a locking block 37. The linkage frame 34 is mounted on the mounting frame 32, and its through-conveyor pipe 28 is located in the inner cavity of the processing cylinder 2. The two ends of the elastic element 36 are connected to the telescopic cylinder 10 and the locking block 37, respectively. The linkage frame 34 is located on the moving path of the locking block 37. When the telescopic cylinder 10 rises to the top, the through hole 27 of the conical block 35 engages with the locking block 37.

[0044] When the lifting plate 8 drives the snap-fit ​​block 37 to rise, the conical block 35 passes through the hole 27 and enters the telescopic cylinder 10, and snaps into the snap-fit ​​block 37, thereby causing the mounting frame 32 to vibrate, which in turn causes the filter box 33 to vibrate.

[0045] Example 3, as Figures 1-3 As shown, the present invention proposes a dual-cylinder sewage treatment device. Compared with Embodiment 1, this embodiment further includes a first conveying pipe 4, a second conveying pipe 6, and two water control pipes 3. The inlet end of the first conveying pipe 4 is connected to the bottom end of the first treatment cylinder 2, and the outlet end of the first conveying pipe 4 is connected to the second treatment cylinder 5. The bottom end of the second treatment cylinder 5 is connected to the inlet end of the second conveying pipe 6. The two water control pipes 3 are respectively connected to the top ends of the first treatment cylinder 2 and the second treatment cylinder 5. After sewage enters the first treatment cylinder 2 from the water control pipe 3 at the top of the first treatment cylinder 2 and undergoes two-stage filtration, disinfectant enters the second treatment cylinder 5 from the second conveying pipe 6. Subsequently, the first conveying pipe 4 transports the sewage to the second treatment cylinder 5 for disinfection and tertiary treatment.

[0046] Water control pipe 3 consists of two circular pipes, a flow meter, and a delivery pump. The flow meter is installed inside the two circular pipes, and the first water pump is installed on the two circular pipes. The water flow rate is controlled by controlling the power of the first delivery pump, and the water flow rate is known in real time through the flow meter, so the water flow rate can be controlled at any time as needed. Delivery pipe 4 and delivery pipe 6 both consist of three circular pipes and a second delivery pump, with the pump installed on the three circular pipes.

[0047] Elastic component 1 (9), elastic component 2 (13), elastic component 3 (15), elastic component 4 (21), elastic component 5 (24), and elastic component 6 (31) are composed of spring 1 and telescopic tube. A set of springs is set outside the telescopic tube or installed inside the telescopic tube.

[0048] The detachable baffle is mounted on the mounting bin 29. The detachable baffle is detached, and the filter box 33 is taken out from the mounting frame 32, so that the impurities are treated. When the lifting plate 8 is lifted to the top of the inner cavity of the treatment cylinder 2, the impurities in the inner cavity of the filter box 33 are treated. At this time, the sewage cannot enter the mounting bin 29 again due to the separation of the hole two 27 and the hole one 26 by the pushing plate 16.

[0049] In the present application, the sewage source is connected with the input end of the water control pipe 3 on the treatment cylinder 2, the disinfectant water input source is connected with the input end of the conveying pipe two 6, and the disinfectant water is conveyed into the inner cavity of the treatment cylinder two 5 through the conveying pipe two 6. The sewage enters the treatment cylinder one 2 from the water control pipe 3, and then the driving device 7 drives the lifting plate 8 to descend in the inner cavity of the treatment cylinder one 2. The sewage enters the telescopic cylinder 10 through the hole one 26 and the hole two 27, and is filtered by the filter plate 11. At this time, the impurities in the sewage are filtered in the telescopic cylinder 10. Then the filtered sewage passes through the filter plate 11, so that the first-stage filtration treatment is completed. When the lifting plate 8 drives the clamping joint 18 to descend between the two triangular blocks 25, the clamping joint 18 is clamped by the two triangular blocks 25. Then the driving device 7 drives the lifting plate 8 to ascend again. During the ascending process, the clamping joint 18 cannot ascend due to the clamping of the clamping joint 18 by the triangular blocks 25. Then the elastic member two 13 is compressed by pulling the pulling rope two 17 to move the pushing plate 16 towards the elastic member three 15, so that the elastic member three 15 is compressed and accumulates elastic potential energy.

[0050] Then the top end of the telescopic cylinder 10 contacts the top end of the inner cavity of the treatment cylinder one 2, and the distance between the lifting plate 8 and the top end of the telescopic cylinder 10 is reduced as the lifting plate 8 continues to ascend. At this time, the pulling rope one 12 is released, and the elastic member two 13 drives the blocking plate 14 to move away from the elastic member two 13, so that the blocking plate 14 blocks part of the filter plate 11, and the filter plate 11 at the bottom of the hole one 26 is not blocked.

[0051] And the hole one 26 is in communication with the water control pipe 3, and the hole two 27 is in communication with the input end of the conveying pipe three 28. When the elastic member one 9 and the telescopic cylinder 10 are compressed to the shortest state, the top end of the pushing plate 16 contacts the top end of the inner cavity of the telescopic cylinder 10, so that the pushing plate 16 separates the hole one 26 and the hole two 27. At this time, the sewage can still enter the hole one 26 and the filter plate 11 for filtration through the water control pipe 3. The pushing plate 16 pulls the pulling rope two 17 to drive the clamping joint 18 to move away from between the two triangular blocks 25, so that the elastic member three 15 releases the elastic member to drive the pushing plate 16 to move towards the hole two 27, so as to squeeze the sewage into the conveying pipe three 28. At the same time, the conveying pipe three 28 conveys the sewage into the filter box 33 in the mounting bin 29. The sewage is filtered by the filter box 33, and then returns to the bottom of the inner cavity of the treatment cylinder one 2 through the one-way pipe 30, and the impurities are left in the filter box 33.

[0052] And after the lifting plate 8 rises, the clamping block 37 pushes the conical block 35 upward for a distance and then is staggered, and the mounting frame 32 is quickly shaken by the elasticity of the elastic member six 31, so that the inner cavity of the filter box 33 is not blocked by impurities. During the descent of the lifting plate 8, the clamping block 37 is lowered to pull the conical block 35 downward for a distance and then is staggered, and the filter box 33 in the mounting frame 32 is shaken again.

[0053] And during the lifting of the lifting plate 8, the pull rope three 19 is activated, the pull rope three 19 pulls the scraper 20 to move, and the scraper 20 moves above the adsorption treatment piece 22 by the elasticity of the elastic member four 21, thereby scraping the debris accumulated on the adsorption treatment piece 22. During the lifting of the lifting plate 8 and the telescopic cylinder 10, a certain downward pressure is generated, so that the sewage can quickly pass through the adsorption treatment piece 22, and then the sewage is adsorbed by the adsorption treatment piece 22, completing the secondary adsorption treatment of the sewage.

[0054] Subsequently, the conveying pipe one 4 conveys the water treated by two stages from the bottom of the treatment cylinder two 5 into the treatment cylinder two 5, and mixes with the disinfectant water in the treatment cylinder two 5, thereby disinfecting the water, completing the three-stage disinfection treatment of the sewage, and then the treated sewage is discharged through the water control pipe 3 at the top of the treatment cylinder two 5.

[0055] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the application.
