[0008] The above technical solution utilizes the rotation of the connecting rod and fan blades, along with the assistance of the guide plate, to break up the wastewater in front of the frame-type mixing blades.

[0009] As a preferred embodiment of the above technical solution, the multiple sets of fan blades are inclined at 15° relative to the connecting rod, and the guide plate is set as a triangle.

[0010] As a preferred embodiment of the above technical solution, the connecting assembly includes a plug rod fixedly connected to the upper end of the first rotating rod, and a second rotating rod is sleeved on the outer side of the upper end of the plug rod, with the upper end of the second rotating rod fixedly connected to the motor output shaft.

[0011] As a preferred embodiment of the above technical solution, the plug-in assembly includes a plug plate inserted inside the plug rod and the second rotating rod, and a baffle is fixedly connected to the end of the plug plate away from the second rotating rod.

[0012] The above technical solution utilizes insert plates and baffles to initially restrict the insert rod and the second rotating rod.

[0013] As a preferred embodiment of the above technical solution, the limiting component includes a card plate inserted inside the end of the insert plate away from the baffle, and the upper end of the card plate is inserted into the second rotating rod.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a high-efficiency wastewater collection pit stirring and mixing device, including a wastewater pit 1, a support 11 fixedly connected to the upper end of the wastewater pit 1, a stirring component 2 arranged in the middle of the support 11, and the stirring component 2 including a motor 21 fixedly connected to the upper end of the support 11, a first rotating rod 22 arranged in the lower end of the motor 21, and a frame-type stirring blade 23 fixedly connected to the lower end of the first rotating rod 22. An auxiliary component 3 is arranged at the end of the frame-type stirring blade 23 away from the first rotating rod 22, which can reduce the resistance when the first rotating rod 22 rotates. A connecting component 4 is arranged in the upper end of the first rotating rod 22, a plug-in component 5 is arranged in the middle of the connecting component 4, and a limiting component 6 is arranged at one end of the plug-in component 5. By cooperating with the stirring component 2 and the auxiliary component 3, the resistance when the stirring and mixing device is operated can be reduced, the power loss can be effectively reduced, and the stirring and mixing efficiency can be improved.

[0020] like Figure 3 As shown, the auxiliary component 3 includes a connecting rod 31 rotatably connected to the outer side of the frame-type stirring blade 23 away from the first rotating rod 22, and a fan blade 32 is fixedly connected to the outer side of the connecting rod 31. Guide plates 33 are fixedly connected to the outer sides of both ends of the frame-type stirring blade 23. After the frame-type stirring blade 23 rotates, it synchronously drives the connecting rod 31, the fan blade 32 and the guide plate 33 to move. At this time, due to its tilt angle, the guide plate 33 rotates under the support of the connecting rod 31 with the help of the resistance of the wastewater during the movement, and exerts a breaking force on the direction of movement of the frame-type stirring blade 23. At the same time, with the assistance of the guide plate 33, it further exerts a breaking force to stir.

[0021] like Figure 3 As shown, multiple sets of fan blades 32 are tilted at 15° relative to the connecting rod 31, and the guide plate 33 is set in a triangle.

[0022] like Figure 4As shown, the connecting component 4 includes a plug rod 41 fixedly connected to the upper end of the first rotating rod 22, and a second rotating rod 42 is sleeved on the outer side of the upper end of the plug rod 41. The upper end of the second rotating rod 42 is fixedly connected to the output shaft of the motor 21. The first rotating rod 22 is used to drive the plug rod 41 to be inserted into the second rotating rod 42 for initial locking and restriction.

[0023] like Figure 4 As shown, the plug-in assembly 5 includes a plug rod 41 and a plug plate 51 inserted inside the second rotating rod 42. A baffle 52 is fixedly connected to one end of the plug plate 51 away from the second rotating rod 42. The baffle 52 is used to drive the plug plate 51 to be inserted into the plug rod 41 and the second rotating rod 42 for locking and limiting.

[0024] like Figure 4 As shown, the limiting component 6 includes a locking plate 61 inserted inside the end of the insert plate 51 away from the baffle 52, and the upper end of the locking plate 61 is inserted into the second rotating rod 42. A spring 62 is fixedly connected to the upper end of the locking plate 61, and the upper end of the spring 62 is fixedly connected to the second rotating rod 42.

[0025] like Figure 4 As shown, a connecting plate 63 is fixedly connected to the outer side of the end of the clamping plate 61 near the spring 62, and a push plate 64 is fixedly connected to the end of the connecting plate 63 away from the spring 62 through the second rotating rod 42. Pushing the push plate 64 causes the connecting plate 63 and the clamping plate 61 to move. After the clamping plate 61 moves, it is inserted into the second rotating rod 42 to compress the spring 62, thereby restricting the insertion plate 51.

[0026] Working principle: When stirring and mixing the wastewater in wastewater pit 1, motor 21 is started under the support of bracket 11. After motor 21 starts, the output shaft drives the second rotating rod 42 to rotate. After the second rotating rod 42 rotates, it drives the first rotating rod 22 and the frame-type stirring blade 23 to rotate through the restriction of the insertion rod 41 and the insertion plate 51. After the frame-type stirring blade 23 rotates, it synchronously drives the connecting rod 31, the fan blade 32 and the guide plate 33 to move. At this time, due to its tilt angle, the guide plate 33 rotates under the support of the connecting rod 31 with the resistance of the wastewater during the movement, exerting a breaking force on the direction of movement of the frame-type stirring blade 23. At the same time, with the assistance of the guide plate 33, the stirring is further enhanced. When the frame-type stirring blade 23 needs to be removed for cleaning later, the push plate 64 is pushed to drive the connecting plate 63 and the clamping plate. Move 61. After the card plate 61 moves, it is inserted into the second rotating rod 42 and the spring 62 is compressed. When the card plate 61 is pulled out of the insert plate 51, the baffle 52 is pulled to drive the insert plate 51 to pull out the insert rod 41 and the second rotating rod 42. Then, the first rotating rod 22 is pulled to drive the insert rod 41 to pull out the second rotating rod 42 for removal. After removing the first rotating rod 22, the frame-type stirring blade 23 is cleaned. After cleaning, the first rotating rod 22 drives the insert rod 41 to be inserted into the second rotating rod 42. Then, the baffle 52 is used to drive the insert plate 51 to be inserted into the insert rod 41 and the second rotating rod 42. During the insertion of the insert plate 51, the push plate 64 is pushed. After the insert plate 51 is inserted, the push plate 64 is released and the elastic potential energy of the spring 62 is used to push the card plate 61 to be inserted into the insert plate 51 for locking and restriction.

[0027] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
