Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment box for sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. With economic development and social progress, more and more fields need to carry out corresponding sewage treatment. People also produce a certain amount of domestic sewage in their daily lives. Due to the small amount of sewage, it is generally collected through underground pipes to sewage treatment plants for centralized treatment. However, in some remote areas that cannot be connected to sewage treatment plants, some small sewage treatment equipment will be used to meet the sewage treatment needs, and sewage treatment tanks are one of them.

[0003] Traditional sewage treatment tanks use filter plates to remove debris in sewage. After a certain period of use, the filter holes on the filter plates will be clogged with debris, requiring shutdown for cleaning, which affects the usable time. Harmful pathogenic bacteria still exist in the filtered sewage, and direct discharge will pollute the surrounding environment. In addition, the internal structure of the sewage treatment tank is complex, and there are many dead corners that are difficult to clean, which increases the difficulty of subsequent cleaning for users.

DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example:

[0031] like Figures 1 to 7As shown, the present embodiment provides a sewage treatment box for sewage treatment, comprising an upper sealing cover 1, a lower base 2 and a bottom plate 3, the bottom plate 3 is provided with a lower base 2, the lower base 2 is detachably connected to the upper sealing cover 1, the upper sealing cover 1 and the lower base 2 connected to each other are cylindrical in overall shape, the upper sealing cover 1 is rotatably connected to an upper rotating rod 4 that can rotate around its central axis, a rotating seat 5 is provided in the middle of the top end of the lower base 2, a lower rotating rod 6 that can rotate around the central axis of the lower base 2 is rotatably connected to the rotating seat 5, the bottom end of the upper rotating rod 4 and the top end of the lower rotating rod 6 are detachably connected and coaxially connected, a power device 7 for driving the upper rotating rod 4 to rotate is provided at the top of the upper sealing cover 1, a rotating frame 8 rotatably connected to the top end of the upper rotating rod 4 is provided at the top of the upper sealing cover 1, a filter plate 9 is detachably connected to the top of the inner cavity of the lower base 2, the upper part of the lower rotating rod 6 passes through the filter plate 9, and the lower part of the lower rotating rod 6 is provided with a pair of left-right symmetrical cross bars 10, and the cross bars 10 are evenly provided with nozzles A11 pointing upward to the filter plate 9 along the length direction and a nozzle B12 pointing downward to the inner cavity of the lower base 2, a docking joint A13 connected to the backwash water source and a docking joint B14 connected to the disinfectant source are provided on the rotating frame 8, an infusion channel A15 for connecting the docking joint A13 with each nozzle A11 and an infusion channel B16 for connecting the docking joint B14 with each nozzle B12 are provided in the rotating frame 8, the upper rotating rod 4, the lower rotating rod 6 and the cross bar 10, and an arc scraper 17 is connected to the left and right sides of the lower part of the upper rotating rod 4. The bottom of the arc scraper 17 abuts against the top of the filter plate 9, and the arc convex surface of the arc scraper 17 is the abutment surface between it and the debris. The outer walls of the upper sealing cover 1 and the lower base 2 are provided with a waste collecting component 18. The connecting part between the waste collecting component 18 and the upper sealing cover 1 is flush with the upper surface of the filter plate 9. The connecting part between the waste collecting component 18 and the lower base 2 is located below the filter plate 9 and a filter screen 19 is provided at the connecting part. A liquid inlet pipe 43 is provided at the top of the upper sealing cover 1, and a liquid outlet pipe 44 is provided at the bottom of the back of the lower base 2.

[0032] The power device 7 drives the upper rotating rod 4 and the connected lower rotating rod 6 to rotate, thereby driving the arc scraper 17 and the cross bar 10 to rotate synchronously. The arc scraper 17 is used to scrape up the debris on the filter plate 9 and move the debris to the outside along its arc convex surface, and finally sweep the debris into the waste collection component 18. The cross bar 10 is provided with a nozzle A11 pointing to the filter plate 9. The joint A13 transmits backwash water to the nozzle A11 through the infusion channel A15. The water flow ejected by the nozzle A11 is used to flush up the debris on the filter plate 9. The accumulation speed of the debris on the filter plate 9 is reduced by two methods, the frequency of cleaning the filter plate 9 is reduced, and the operating time is extended. When the waste collection component 18 collects the debris, the sewage entering with the debris is filtered by the filter net 19 and falls into the lower base 2, which does not affect the filtering operation. After the sewage filtered by the filter plate 9 falls into the lower base 2, the joint B14 delivers the disinfectant to the nozzle B12 through the infusion channel B16. The nozzle B12 evenly sprinkles the disinfectant into the sewage in the lower base 2 when rotating with the cross bar 10. The sewage has been filtered and disinfected to a certain extent when discharged from the liquid outlet pipe 44, and the filtering effect is good. Generally, a valve is set in the liquid outlet pipe 44 to allow the sewage to stay in the lower base 2 for a period of time so that the disinfectant can take effect. The valve is not drawn in the attached figure. The upper sealing cover 1 and the lower base 2 are detachably connected, the upper rotating rod 4 and the lower rotating rod 6 are detachably connected, and the filter plate 9 and the lower base 2 are detachably connected, which is convenient for the user to disassemble the device and clean the upper sealing cover 1, the lower base 2 and the filter plate 9 respectively.

[0033] Furthermore, the part of the infusion channel A15 on the rotating frame 8 is a cavity leading from the docking joint A13 to the top of the upper rotating rod 4, the part on the upper rotating rod 4 is composed of an annular cavity at the top of the upper rotating rod 4 and a vertical cavity leading from the annular cavity to the bottom of the upper rotating rod 4, and the part on the lower rotating rod 6 and the cross bar 10 is composed of an annular cavity at the top of the lower rotating rod 6 and two L-shaped cavities leading from the annular cavity to the nozzles A11 on the left and right sides respectively; the part of the infusion channel B16 on the rotating frame 8 is a cavity leading from the docking joint B14 to the top of the upper rotating rod 4, the part on the upper rotating rod 4 is a vertical cavity along the central axis of the upper rotating rod 4, and the part on the lower rotating rod 6 and the cross bar 10 is an inverted T-shaped cavity leading from the top of the lower rotating rod 6 to the nozzles B12 on the left and right sides.

[0034] In the infusion channel A15, the annular cavity part at the top of the upper rotating rod 4 is designed to be connected with the part of the rotating frame 8 when the upper rotating rod 4 rotates, and the annular cavity part at the top of the lower rotating rod 6 is designed to allow the backwash water flowing down from the upper rotating rod 4 to be evenly distributed into the two L-shaped cavities; in the infusion channel B16, because the vertical cavity part in the upper rotating rod 4 is on the rotation axis of the upper rotating rod 4, its vertical cavity will not be offset when the upper rotating rod 4 rotates, so the cavity tail in the rotating frame 8 and the cavity head in the lower rotating rod 6 only need to be connected with the upper and lower ends of the cavity in the upper rotating rod 4 to maintain long-term connection.

[0035] Furthermore, the waste collection assembly 18 includes an upper shell 20, a lower shell 21 and an opening and closing assembly 22. The upper shell 20 is connected to the side wall of the upper sealing cover 1, and the connection between the upper shell 20 and the upper sealing cover 1 is flush with the upper surface of the filter plate 9. The upper shell 20 is provided with an opening and closing assembly 22 for controlling the opening and closing of the connection between the upper shell 20 and the upper sealing cover 1. The lower shell 21 is connected to the side wall of the lower base 2, and the connection between the lower shell 21 and the lower base 2 is lower than the filter plate 9 and a filter screen 19 is provided at the connection. The upper shell 20 is connected to the lower shell 21, and the upper shell 20 and the lower shell 21 are detachably connected. A waste outlet 23 is provided at the bottom of the lower shell 21, and a sealing plate 24 is hinged on the waste outlet 23.

[0036] When the arc scraper 17 rotates, the opening and closing component 22 is opened to allow debris to smoothly enter the space surrounded by the upper shell 20 and the lower shell 21. When there are too many debris that need to be cleaned up, the opening and closing component 22 is closed, and the waste collecting component 18 temporarily stops receiving the debris to prevent sewage from being accidentally discharged from the waste outlet 23. Then, the sealing plate 24 is opened to release the debris from the waste outlet 23. When the debris is emptied, the user closes the sealing plate 24 again and opens the opening and closing component 22.

[0037] Furthermore, the opening and closing assembly 22 includes an outer arc plate 25, a connecting plate 26, a rotating head 27 and a handle 28. The upper shell 20 is cylindrical in shape. The top of the upper shell 20 is rotatably connected to a rotating head 27 that rotates around its central axis. A handle 28 is provided on the top of the rotating head 27, and a connecting plate 26 is provided at the bottom of the rotating head 27. The end of the connecting plate 26 is connected to the outer arc plate 25. The outer wall of the outer arc plate 25 fits the side wall of the inner cavity of the upper shell 20. The outer arc plate 25 can rotate around the central axis of the upper shell 20. The opening and closing of the connection between the upper shell 20 and the upper cover 1 can be changed by adjusting the position of the outer arc plate 25.

[0038] The user holds the handle 28 and rotates it, driving the outer arc plate 25 to rotate via the rotating head 27 and the connecting plate 26. When the outer arc plate 25 blocks the connection between the upper shell 20 and the upper sealing cover 1, it can prevent debris in the upper sealing cover 1 from entering the upper shell 20. When the outer arc plate 25 is removed from the connection, debris can enter the upper shell 20.

[0039] Furthermore, a circular track 29 concentric with the rotating head 27 is provided on the top of the upper shell 20, and a slider 30 sliding along the circular track 29 is provided on the rotating head 27. Grooves 31 are symmetrically provided at the left and right ends of the circular track 29, and a spring piece 32 that can be inserted into the groove 31 is provided on the slider 30. When the slider 30 rotates to the left and right ends of the circular track 29, the outer arc plate 25 rotates to the connecting point between the upper shell 20 and the upper sealing cover 1 or its corresponding position.

[0040] The outer arc plate 25 is accurately positioned and stays at the designated position by the cooperation of the spring piece 32 and the groove 31. Because the opening and closing needs to be controlled, the outer arc plate 25 is generally stopped at the connection point between the upper shell 20 and the upper cover 1 or its corresponding position. When the outer arc plate 25 needs to switch positions, the user holds the handle 28 and rotates it. At the beginning, extra force is required to overcome the elastic force of the spring piece 32, so that the spring piece 32 is deformed and squeezed out of the groove 31 and returns to the circular track 29. After the outer arc plate 25 rotates to the predetermined position, the spring piece 32 slides from the circular track 29 into the groove 31, and the spring piece 32 returns to its original state and is stuck in the groove 31. The user's hand feeling when turning the handle 28 will change, so that the outer arc plate 25 is correctly positioned, and the spring piece 32 stuck in the groove 31 will produce resistance to prevent the rotating head 27 from continuing to rotate, helping the outer arc plate 25 to stay at the designated position.

[0041] Furthermore, a fixing ring 33 is provided along the circumference of the top of the inner cavity of the lower base 2, and insertion blocks 34 are evenly provided on the upper surface of the fixing ring 33. An insertion groove 35 corresponding to the insertion block 34 is provided at the outer edge of the bottom of the filter plate 9, and an annular groove 36 is provided along the circumference of the inner edge of the fixing ring 33. A protrusion 37 slidably connected to the annular groove 36 is provided at the outer end of the cross bar 10. The insertion block 34 and the insertion groove 35 cooperate to realize the detachable connection between the filter plate 9 and the fixing ring 33, and the rotation of the cross bar 10 is more stable through the cooperation of the protrusion 37 and the annular groove 36.

[0042] Furthermore, the filter plate 9 comprises a pair of mirror-symmetrical semicircular plates. The filter plate 9 is divided into two, which reduces the difficulty of its assembly and disassembly operation.

[0043] Furthermore, a stirring frame 38 is rotatably connected to the middle of the bottom of the lower base 2, and a motor 39 is provided at the bottom of the bottom plate 3, and a driving rod of the motor 39 is coaxially connected to the rotating shaft of the stirring frame 38. The stirring frame 38 is driven to rotate by the motor 39, and the stirring of the stirring frame 38 accelerates the speed of the disinfectant mixing into the sewage, thereby improving the treatment efficiency.

[0044] Furthermore, docking blocks 40 are evenly arranged along the edge of the bottom end of the upper rotating rod 4, and docking grooves 41 corresponding to the docking blocks 40 are evenly arranged along the edge of the top end of the lower rotating rod 6. The docking blocks 40 and the docking grooves 41 are used together to realize a detachable connection between the bottom end of the upper rotating rod 4 and the top end of the lower rotating rod 6, and the assembly and disassembly are convenient. When the upper sealing cover 1 is separated from the lower base 2, the docking blocks 40 can be pulled out of the docking grooves 41 without additional operation.

[0045] Furthermore, self-locking universal wheels 42 are evenly arranged along the edge of the bottom of the bottom plate 3. The self-locking universal wheels 42 give the bottom plate 3 the ability to move flexibly, reducing the difficulty of transfer. When transfer is required, the user unlocks the self-locking universal wheels 42, and when staying, the user locks the self-locking universal wheels 42.

[0046] The working principle and use process of this utility model:

[0047] When treating sewage, the user unlocks the self-locking universal wheel 42, and relocks it after moving the bottom plate 3 to the specified position, and introduces sewage from the liquid inlet pipe 43. The amount of sewage added at one time should be appropriate, and the sewage in the lower base 2 should not overflow the filter screen 19 and the nozzle B12. The power device 7 is started to drive the upper rotating rod 4 and the lower rotating rod 6 to rotate, and the arc scraper 17 and the cross bar 10 to rotate. The debris blocked by the filter plate 9 is swept into the waste collection component 18 by the arc scraper 17. The docking joint A13 and the docking joint B14 respectively send backwash water and disinfectant to the nozzle A11 and the nozzle B12 through the infusion channel A15 and the infusion channel B16. The nozzle A11 sprays water upward to wash the filter plate 9, and the nozzle B12 sprays disinfectant downward. The motor 39 drives the stirring frame 38 to rotate to stir the sewage and the disinfectant. Finally, the treated sewage is discharged from the liquid outlet pipe 44. When the waste collecting assembly 18 needs to be cleaned during use, the opening and closing assembly 22 is closed, the sealing plate 24 is opened, and debris is emptied from the waste outlet 23 , and then the sealing plate 24 is closed and the opening and closing assembly 22 is reopened.

[0048] During subsequent cleaning, the user separates the upper sealing cover 1 and the lower base 2 from each other, removes the filter plate 9 from the fixing ring 33, and then completes the cleaning work one by one.

[0049] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
