At the same time, a large amount of sludge after treatment is accumulated at the bottom of the sedimentation tank. After the sewage treatment is completed, the sedimentation tank cannot be cleaned well, which consumes time and effort, and the working efficiency is low, thereby affecting the sewage treatment efficiency.

[0007] A cleaning mechanism comprises a transmission shaft and an installation gear ring, the transmission shaft is arranged on one side of the driving shaft, and the transmission shaft is in transmission connection with the driving shaft, the installation gear ring is rotatably installed in the treatment box, the bottom of the transmission shaft penetrates the top wall of the treatment box, and a transmission spur gear meshing with the installation gear ring is installed on one end of the transmission shaft located inside the treatment box, and the installation gear ring is connected with a cleaning assembly for cleaning the inner wall of the treatment box.

[0008] In a further technical solution, the cleaning component includes a plurality of contour rods arranged in a ring on a mounting toothed ring. The contour rods have the same cross-sectional shape as the side wall of the treatment chamber, and a cleaning brush is provided on the side of the contour rods near the inner wall of the treatment chamber. A plurality of stirring rods are installed vertically on the side of the contour rods away from the inner wall of the treatment chamber.

[0009] In a further technical solution, the transmission shaft and the drive shaft are connected to each other by a pair of meshing bevel gears.

[0010] In a further technical solution, an adjustment component for adjusting the connection state between the transmission shaft and the drive shaft is provided on one side of the transmission shaft.

The mounting gear ring then moves the cleaning components. Specifically, the mounting gear ring drives a contour rod to rotate, and the cleaning brush on the contour rod cleans the inner wall of the treatment tank, preventing sludge deposition. Simultaneously, the contour rod also drives a stirring rod to rotate, thus agitating the wastewater in the treatment tank and ensuring more thorough mixing of the wastewater and the wastewater treatment liquid, further improving wastewater treatment efficiency. Furthermore, the liquid supply assembly pumps the wastewater treatment liquid into the delivery shaft. Under the water pressure of the wastewater treatment liquid, the delivery shaft slides along the drive shaft, aligning the drain hole with the through hole. At this point, the wastewater treatment liquid can be sprayed into the wastewater through the through hole. Simultaneously, the rotation of the rollers and blades ensures more even contact between the wastewater treatment liquid and the wastewater, thereby improving wastewater treatment efficiency. When the liquid supply assembly stops working, the delivery shaft returns to its initial position under the elastic restoring force of the return spring. The drain hole and through hole are then misaligned again, preventing wastewater in the installation cavity from flowing back into the delivery shaft. This device utilizes the kinetic energy generated by the flow of wastewater to achieve efficient mixing of the wastewater treatment liquid and cleaning of the inside of the treatment tank. It features low energy consumption, high efficiency, and excellent performance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-6 As shown, a low-energy wastewater treatment device according to an embodiment of the present invention includes a base 1, an mounting frame 11 mounted on the base 1, a treatment tank 13 mounted on the base 1, and the treatment tank 13 mounted on a mounting bracket 12 mounted on the base 1. A water pump 2 is mounted on the mounting frame 11, and the water pump 2 is connected to a vertically installed primary treatment pipe 22 via a connecting pipe 21. The primary treatment pipe 22 communicates with the top of the treatment tank 13. The device also includes:

[0025] A drive assembly 3 is installed in a mounting cavity 23 on the pretreatment pipe 22. The drive assembly 3 includes a drive shaft 31 rotatably mounted in the mounting cavity 23, a rotating roller 32 mounted on the drive shaft 31, and blades 33 arranged in a ring on the rotating roller 32. Through holes 34 are provided on the sidewalls of both the drive shaft 31 and the rotating roller 32, and these through holes 34 communicate with each other. An infusion shaft 35 is also slidably mounted in the drive shaft 31. One end of the infusion shaft 35 is connected to one end of the drive shaft 31 via a return spring 36. Several drainage holes 37 are provided on the sidewall of the infusion shaft 35, and these drainage holes 37 are offset from the through holes 34. A liquid supply assembly 4 is connected to the end of the infusion shaft 35 located outside the drive shaft 31.

[0026] The cleaning mechanism 5 includes a drive shaft 51 and a mounting gear ring 52. The drive shaft 51 is located on one side of the drive shaft 31 and is connected to the drive shaft 31 in a driving manner. The mounting gear ring 52 is rotatably mounted in the processing box 13. The bottom of the drive shaft 51 penetrates the top wall of the processing box 13, and a drive spur gear 53 that meshes with the mounting gear ring 52 is installed at one end of the drive shaft 51 inside the processing box 13. The mounting gear ring 52 is connected to a cleaning component for cleaning the inner wall of the processing box 13.

[0027] In this embodiment of the invention, the transmission shaft 51 and the drive shaft 31 are connected to each other by a pair of meshing bevel gears. In use, the water pump 2 pumps sewage into the pretreatment pipe 22 through the connecting pipe 21. The sewage impacts the rotating roller 32 and blades 33 in the mounting cavity 23, causing the drive shaft 31 and the rotating roller 32 to rotate synchronously. The drive shaft 31 drives the transmission shaft 51 to rotate through a pair of meshing bevel gears. Under the cooperation of the mounting gear ring 52 and the transmission spur gear 53, the transmission shaft 51 can drive the mounting gear ring 52 to rotate. The mounting gear ring 52 drives the cleaning component to continuously clean the inner wall of the treatment tank 13, and at the same time, it can also mix the sewage in the treatment tank 13. In addition, the liquid supply assembly 4 can pump the sewage treatment liquid into the delivery shaft 35. Under the water pressure of the sewage treatment liquid, the delivery shaft 35 will slide along the drive shaft 31, thereby aligning the drain hole 37 with the through hole 34. At this time, the sewage treatment liquid can be sprayed into the sewage from the through hole 34. Simultaneously, with the rotation of the rotating roller 32 and the blade 33, the sewage treatment liquid can be more evenly contacted with the sewage, thereby improving the efficiency of sewage treatment. When the liquid supply assembly 4 stops working, under the elastic restoring force of the return spring 36, the delivery shaft 35 will return to its initial position. At this time, the drain hole 37 and the through hole 34 will be misaligned again, and the sewage in the mounting cavity 23 will not flow back into the delivery shaft 35.

[0028] like Figure 1 and 5 As shown, in a preferred embodiment of the present invention, the cleaning assembly includes a plurality of contour rods 54 arranged in a ring on the mounting toothed ring 52. The contour rods 54 have the same cross-sectional shape as the side wall of the treatment box 13. A cleaning brush 55 is provided on the side of the contour rods 54 near the inner wall of the treatment box 13, and a plurality of stirring rods 56 are installed vertically on the side of the contour rods 54 away from the inner wall of the treatment box 13.

[0029] In this embodiment of the invention, during use, the mounting toothed ring 52 drives the contour rod 54 to rotate. The cleaning brush 55 on the contour rod 54 cleans the inner wall of the treatment tank 13 to prevent sludge deposition. At the same time, the contour rod 54 also drives the stirring rod 56 to rotate, thereby stirring the sewage in the treatment tank 13, making the sewage and sewage treatment liquid more fully mixed, and further improving the sewage treatment efficiency.

[0030] like Figure 1 and 2 As shown, in a preferred embodiment of the present invention, an adjustment component 6 for adjusting the connection state between the transmission shaft 51 and the drive shaft 31 is provided on one side of the transmission shaft 51.

[0031] In this embodiment of the invention, the adjusting component 6 includes an electric telescopic rod 61 and a sliding sleeve 63. The sliding sleeve 63 is mounted on a drive shaft 51 and connected to the drive shaft 51 via a key. A bevel gear on the drive shaft 51 is mounted on the sliding sleeve 63. The electric telescopic rod 61 is located on one side of the drive shaft 51, and a connecting plate 62 is connected to the movable end of the electric telescopic rod 61. The sliding sleeve 63 is rotatably mounted on the connecting plate 62. In use, the electric telescopic rod 61 can drive the connecting plate 62 to move, and the connecting plate 62 drives the sliding sleeve 63 to slide along the axial direction of the drive shaft 51, thereby adjusting the connection state between the bevel gear on the sliding sleeve 63 and the bevel gear on the drive shaft 31. Under the adjusting action of the adjusting component 6, the cleaning mechanism 5 can have the following working modes:

[0032] (1) Used to stir and mix the sewage in the treatment tank 13. During this process, the drive shaft 51 is always connected to the drive shaft 31. Through the continuous operation of the cleaning mechanism 5, the sewage in the treatment tank 13 can be stirred, so that the sewage treatment liquid and sewage are more fully mixed, which can improve the efficiency of sewage treatment.

[0033] (2) During the sedimentation stage, the transmission shaft 51 is disconnected from the transmission connection with the drive shaft 31, the cleaning mechanism 5 is in a non-working state, and the sewage in the treatment tank 13 reacts with the sewage treatment liquid and can be fully sedimented.

[0034] (3) Used to clean the inner wall of the treatment box 13. During this process, the transmission shaft 51 is connected to the drive shaft 31 again, and the water pump 2 pumps clean water (which can be sewage treated by the device) into the primary treatment pipe 22. At this time, the cleaning mechanism 5 will continue to work, and the cleaning brush 55 on the contour rod 54 can clean the inner wall of the treatment box 13 and rinse with clean water, so as to effectively remove the sludge and other impurities deposited in the treatment box 13 and keep the inside of the treatment box 13 clean.

[0035] like Figure 1 As shown, in a preferred embodiment of the present invention, the liquid supply assembly 4 includes a liquid storage tank 41 and a liquid pump 42 mounted on the mounting frame 11. The inlet end of the liquid pump 42 is connected to the liquid storage tank 41, and the outlet end of the liquid pump 42 is connected to the delivery shaft 35 through a liquid guide pipe 43. The liquid guide pipe 43 and the delivery shaft 35 are rotatably connected.

[0036] In this embodiment of the invention, the liquid pump 42 can pump the sewage treatment liquid in the storage tank 41 into the delivery shaft 35 through the liquid guide pipe 43 and provide thrust so that the drain hole 37 is connected to the through hole 34, thereby smoothly spraying the sewage treatment liquid into the mounting cavity 23 so that it can fully contact the sewage.

[0037] like Figure 1 As shown, in a preferred embodiment of the present invention, the bottom of the treatment box 13 is hemispherical, and a drain outlet is provided at the bottom of the treatment box 13. The hemispherical bottom and the drain outlet facilitate the discharge of sludge and other impurities.

[0038] Working Principle: During operation, the water pump 2 pumps sewage into the pretreatment pipe 22 through the connecting pipe 21. The sewage impacts the rotating roller 32 and blades 33 in the mounting cavity 23, causing the drive shaft 31 and the rotating roller 32 to rotate synchronously. The drive shaft 31 drives the transmission shaft 51 to rotate through a pair of meshing bevel gears. Under the cooperation of the mounting gear ring 52 and the transmission spur gear 53, the transmission shaft 51 drives the mounting gear ring 52 to rotate. The mounting gear ring 52 drives the cleaning components to move. Specifically, the mounting gear ring 52 drives the contour rod 54 to rotate. The cleaning brush 55 on the contour rod 54 cleans the inner wall of the treatment tank 13 to prevent sludge deposition. At the same time, the contour rod 54 also drives the stirring rod 56 to rotate, thereby stirring the sewage in the treatment tank 13, making the sewage and sewage treatment liquid more thoroughly mixed, and further improving the sewage treatment efficiency. In addition, the liquid supply assembly 4 can pump the sewage treatment liquid into the delivery shaft 35. Under the water pressure of the sewage treatment liquid, the delivery shaft 35 will slide along the drive shaft 31, thereby aligning the drain hole 37 with the through hole 34. At this time, the sewage treatment liquid can be sprayed into the sewage from the through hole 34. Simultaneously, with the rotation of the rotating roller 32 and the blade 33, the sewage treatment liquid can be more evenly contacted with the sewage, thereby improving the efficiency of sewage treatment. When the liquid supply assembly 4 stops working, under the elastic restoring force of the return spring 36, the delivery shaft 35 will return to its initial position. At this time, the drain hole 37 and the through hole 34 will be misaligned again, and the sewage in the mounting cavity 23 will not flow back into the delivery shaft 35.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
