[0008] As a preferred embodiment of the above technical solution, a groove is provided on the outer surface of the stirring rod, the extrusion rod is movably connected to the inside of the groove, the end of the extrusion rod away from the stirring rod is hinged to the cleaning scraper, and the extrusion rod is symmetrically arranged with respect to the center of the stirring rod.

[0009] As a preferred embodiment of the above technical solution, the ends of the first fixed rod and the second fixed rod are fixedly sleeved with mounting blocks, one end of the cylinder-to-cleaning brush passes through the stirring rod and is fixedly connected to the mounting blocks, the electric push rod is located between the mounting blocks, the bottom of the telescopic end of the electric push rod is provided with a movable cavity, the top end of the second fixed rod passes through the push plate and is movably connected to the movable cavity, the push plate is located on the top of the buffer plate, and a compression spring is fixedly connected between the two buffer plates.

[0010] As a preferred embodiment of the above technical solution, the cleaning brush is located at the upper and lower ends of the cleaning scraper, and a squeezing block is fixedly connected to one side of the outer surface of the cleaning scraper and at the top of the through hole. The end of the squeezing block away from the cleaning scraper is an inclined surface.

[0011] As a preferred embodiment of the above technical solution, the cleaning brush includes an adjusting block, one side of which is fixedly connected to a cylinder, an adjusting component is provided inside the adjusting block, a connecting block is fixedly connected to one side of the adjusting block, and a cleaning port is provided at equal intervals on the outer surface of one side of the connecting block. Brush bristles are fixedly connected around the cleaning port and on the outer surface of one side of the connecting block.

[0012] As a preferred embodiment of the above technical solution, the adjusting component includes a squeezing ball, the outer surface of which is movably connected to the squeezing groove, a return spring fixedly connected to the bottom of the squeezing ball, a moving block fixedly connected to the bottom of the return spring, and a sealing plug fixedly connected to the bottom of the moving block, the sealing plug being located at the bottom of the outlet.

[0013] As a preferred embodiment of the above technical solution, the adjusting block has a squeezing groove on the side near the cleaning scraper, and an installation groove on one side of the squeezing groove. A water storage tank is fixedly installed inside the installation groove, and a water outlet is provided at the bottom of the water storage tank. A water collection trough is provided at the bottom of the installation groove. A water outlet pipe is fixedly connected to the side of the water collection trough near the connecting block, and a water distribution pipe is fixedly connected to one side of the water outlet pipe. The water distribution pipe is located inside the connecting block, and a nozzle is fixedly connected to one side of the water distribution pipe. The nozzle is located inside the cleaning port.

[0014] The present invention also provides a method for using the above-described efficient impurity removal stirring device, the method comprising the following steps:

[0015] Step 1: First, pour the wastewater into the mixing drum through the inlet, start the motor to drive the stirring rod to rotate and stir the wastewater. Observe the stirring inside the mixing drum through the square observation port.

[0016] Step 2: Then, while the stirring rod rotates, it drives the cleaning brush to rotate and clean the inner wall of the stirring drum. Then, by activating the electric push rod, the push plate is pushed downward to squeeze the buffer plate, which compresses the compression spring. This causes the buffer plate to move downward on the second fixed rod to squeeze the squeezing rod. The squeezing rod is squeezed and deflects upward, pushing the cleaning scraper to move closer to the cleaning brush. By controlling the electric push rod, the cleaning scraper cleans the dirt remaining on the stirring shaft.

[0017] Step 3: Then, when the cleaning scraper moves to one end of the stirring rod, the movement of the electric push rod, along with the activation of the cylinder, causes the cylinder to retract into the stirring shaft, moving the cleaning brush away from the inner wall of the stirring drum and back to its original position. At the same time, the squeezing block on the cleaning scraper inserts into the squeezing groove on one side of the cleaning brush, squeezing the squeezing ball. This causes the return spring to compress and push the moving block downwards. The moving block moves the sealing plug away from the water outlet, allowing the water in the water tank to flow into the water collection tank. The water is then sprayed onto the brush bristles through the water outlet pipe and the water distribution pipe.

[0018] Step 4: Finally, use the rotation of the stirring rod to drive the cleaning brush to rotate, which in turn drives the brush bristles to rotate, so that the dirt on the cleaning brush is cleaned. Then stop the rotation of the motor and discharge the fully stirred wastewater through the outlet pipe.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. Through the coordinated use of a motor, stirring rod, extrusion device, stirring shaft, cleaning brush, and cleaning scraper, the motor drives the stirring rod and stirring shaft to rotate, and the cleaning brush on the stirring shaft rotates, so that the cleaning brush cleans the inner wall of the stirring drum. At the same time, the extrusion device moves the cleaning scraper on the stirring shaft to clean the stirring shaft, preventing dirt from accumulating on the inner wall of the stirring drum and stirring shaft, which would reduce the quality of wastewater treatment and affect the effect of wastewater treatment.

[0021] 2. Through the coordinated use of the motor, stirring rod, stirring shaft, extrusion block, adjusting block, connecting block and adjusting component, the extrusion block is inserted into the adjusting block, causing the adjusting component to move and spray water from the water tank into the bristles through the outlet pipe and water distribution pipe. At the same time, the rotation of the stirring shaft drives the cleaning brush to rotate, so that the dirt on the bristles is cleaned and the dirt is prevented from remaining on the cleaning brush and affecting the cleaning effect.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] This invention provides a multifunctional electrical equipment testing device, such as... Figure 1 , Figure 2 , Figure 4 As shown, a stirring drum 1 has a square observation port 2 at its front end. A liquid outlet pipe is fixedly installed and connected to the bottom of the stirring drum 1. Two support legs are fixedly installed on both sides of the liquid outlet pipe at the bottom of the stirring drum 1. A liquid inlet 3 is opened at the top of the stirring drum 1. A motor 4 is fixedly connected to the top of the stirring drum 1 and to one side of the liquid inlet 3. A stirring rod 5 is fixedly connected to the output end of the motor 4. A cavity is opened inside the stirring rod 5. A squeezing device 6 is installed inside the cavity. A stirring shaft 7 is fixedly connected to the outer surface of the stirring rod 5. A cleaning brush 8 is installed on one side of the stirring shaft 7. One side of the cleaning brush 8 is in contact with the inside of the stirring drum 1. A cleaning scraper 9 is installed on the outer side of the stirring shaft 7.

[0034] Wastewater is poured into the interior of the mixing drum 1 through the inlet pipe. The motor 4 is started to drive the stirring rod 5 to rotate. The stirring rod 5 drives the stirring shaft 7 to rotate. The stirring shaft 7 drives the cleaning brush 8 to rotate, so that the cleaning brush 8 cleans the inner wall of the mixing drum 1. At the same time, the squeezing device 6 is started to move the cleaning scraper 9 on the stirring shaft 7 to clean the dirt on the stirring shaft 7, so that the dirt is not easy to remain and the wastewater treatment effect is improved.

[0035] like Figure 1-3 As shown, the cleaning scraper 9 has through holes at both the top and bottom. The stirring shaft 7 is movably connected to the cleaning scraper 9 through the through holes. The stirring shaft 7 has a movable groove inside, and a cylinder 10 is movably connected inside the movable groove. The telescopic end of the cylinder 10 is fixedly connected to the cleaning brush 8.

[0036] The cleaning scraper 9 moves back and forth on the stirring shaft 7 through the through hole, so that the dirt on the stirring shaft 7 is cleaned. The extension and retraction of the cylinder 10 drives the cleaning brush 8 to move. The cylinder 10 moves to the outside of the stirring shaft 7 so that the cleaning brush 8 fits against the inner wall of the stirring drum 1. The rotation of the stirring shaft 7 drives the cleaning brush 8 to rotate, which facilitates the cleaning of the dirt on the inner wall of the stirring drum 1.

[0037] like Figure 5-6 As shown, the extrusion device 6 includes a first fixed rod 61, the top of which is fixedly connected to the top inner wall of the cavity, an electric push rod 62 is fixedly connected to the bottom of the first fixed rod 61, a push plate 63 is fixedly connected to the bottom of the electric push rod 62, a second fixed rod 64 is provided on the top of the push plate 63, the bottom of the second fixed rod 64 is fixedly connected to the bottom inner wall of the cavity, two buffer plates 65 are movably sleeved on the top of the second fixed rod 64, and an extrusion rod 66 is hinged to the bottom of the two buffer plates 65 and located on the outer surface of the second fixed rod 64. A groove is provided on the outer surface of the stirring rod 5, and the extrusion rod 66 is movably connected to the inside of the groove. The end of the extrusion rod 66 away from the stirring rod 5 is hinged to the cleaning scraper 9. The extrusion rod 66 is symmetrically arranged with respect to the center of the stirring rod 5.

[0038] The electric push rod 62 is fixed by the first fixed rod 61. The electric push rod 62 pushes the push plate 63 to move downward. The push plate 63 moves downward and squeezes the buffer plate 65, so that the buffer plate 65 moves downward on the second fixed rod 64 and squeezes the squeezing rod 66. The squeezing rod 66 is squeezed and deflects upward in the groove, so that the squeezing rod 66 pushes the cleaning scraper 9 from both sides of the stirring rod 5 to move closer to the cleaning brush 8, which facilitates the cleaning of the stirring shaft 7.

[0039] like Figure 4-5 As shown, the ends of the first fixed rod 61 and the second fixed rod 64 are fixedly sleeved with mounting blocks 11. One end of the cylinder 10 far from the cleaning brush 8 passes through the stirring rod 5 and is fixedly connected to the mounting block 11. The electric push rod 62 is located between the mounting blocks 11. The bottom of the telescopic end of the electric push rod 62 is provided with a movable cavity. The top end of the second fixed rod 64 passes through the push plate 63 and is movably connected to the movable cavity. The push plate 63 is located on the top of the buffer plate 65. A compression spring is fixedly connected between the two buffer plates 65.

[0040] The cylinder 10 is fixed by the mounting block 11, which facilitates the cylinder 10 to push the cleaning brush 8 to move and fit against the inner wall of the mixing drum 1. The electric push rod 62 pushes the push plate 63 to move downward, so that the second fixed rod 64 moves into the interior of the movable cavity, which facilitates the push plate 63 to move in the direction of the second fixed rod 64 to squeeze the buffer plate 65. The buffer plate 65 squeezes the compression spring, which facilitates the squeezing rod 66 under the action of the compression spring, so that the squeezing rod 66 deflects, which facilitates the squeezing rod 66 to push the cleaning scraper 9 to move.

[0041] like Figure 1-2 As shown, the cleaning brush 8 is located at the upper and lower ends of the cleaning scraper 9. A squeezing block 12 is fixedly connected to one side of the outer surface of the cleaning scraper 9 and at the top of the through hole. The end of the squeezing block 12 away from the cleaning scraper 9 is a slope.

[0042] The cleaning scraper 9 moves to one end of the stirring shaft 7, and the cylinder 10 retracts, bringing the cleaning brush 8 close to the stirring shaft 7. The brush 8 is inserted into the squeezing groove 16 through the squeezing block 12. Due to the slope of one side of the cleaning brush 8, the squeezing rod 66 can squeeze the adjustment component, which facilitates the movement of the adjustment component and allows water to be sprayed onto the cleaning brush 8 for cleaning, preventing dirt residue from remaining on the cleaning brush 8.

[0043] like Figure 4 , Figure 7 , Figure 8 As shown, the cleaning brush 8 includes an adjusting block 81. One side of the adjusting block 81 is fixedly connected to the cylinder 10. An adjusting component is provided inside the adjusting block 81. A connecting block 82 is fixedly connected to one side of the adjusting block 81. A cleaning port 83 is provided on the outer surface of one side of the connecting block 82 at equal intervals. Brush bristles 84 are fixedly connected around the cleaning port and on the outer surface of one side of the connecting block 82.

[0044] The cylinder 10 drives the adjusting block 81 to move, which facilitates the movement of the connecting block 82 and the bristles 84. The bristles 84 adhere to the inner wall of the mixing drum 1. The cleaning port 83 facilitates the connection of the nozzle 19, which sprays water from the adjusting block 81 onto the bristles 84, making it easier to wash away dirt from the bristles 84 and improve the cleaning effect of the bristles 84.

[0045] like Figure 6-8 As shown, the adjustment assembly includes a squeezing ball 13, the outer surface of which is movably connected to a squeezing groove 16. A return spring 14 is fixedly connected to the bottom of the squeezing ball 13, a moving block 15 is fixedly connected to the bottom of the return spring 14, and a sealing plug is fixedly connected to the bottom of the moving block 15. The sealing plug is located at the bottom of the water outlet. A squeezing groove 16 is provided on the side of the adjustment block 81 near the cleaning scraper 9. An installation groove is provided on one side of the squeezing groove 16. A water storage tank 17 is fixedly installed inside the installation groove. A water outlet is provided at the bottom of the water storage tank 17. A water collection trough is provided at the bottom of the installation groove. A water outlet pipe 18 is fixedly connected to the side of the water collection trough near the connecting block 82. A water distribution pipe is fixedly connected to one side of the water outlet pipe 18. The water distribution pipe is located inside the connecting block 82. A nozzle 19 is fixedly connected to one side of the water distribution pipe. The spray group 19 is located inside the cleaning port 83.

[0046] The squeezing block 12 is inserted into the squeezing groove 16 on one side of the adjusting block 81 to squeeze the squeezing ball 13, which compresses the return spring 14. Under the action of the return spring 14, the moving block 15 is squeezed, which causes the moving block 15 to move the sealing plug. The moving sealing plug separates from the water outlet pipe 18 at the bottom of the water storage tank 17, allowing the water inside the water storage tank 17 to flow into the water collection tank. The water inside the water collection tank flows into the water distribution pipe through the water outlet pipe 18. The water distribution pipe delivers the water to the nozzle 19 in the cleaning port 83. The nozzle 19 sprays water onto the bristles 84 to rinse the bristles 84 and keep them clean.

[0047] like Figure 9 As shown, the present invention also provides a method for using the above-described efficient impurity removal stirring device, the method comprising the following steps:

[0048] Step 1: First, pour the wastewater into the mixing drum 1 through the inlet 3, start the motor 4, and make the motor 4 drive the stirring rod 5 to rotate to stir the wastewater. Observe the stirring inside the mixing drum 1 through the square observation port 2.

[0049] Step 2: Then, while the stirring rod 5 rotates, it drives the cleaning brush 8 to rotate and clean the inner wall of the stirring drum 1. Then, by activating the electric push rod 62, the push plate 63 is pushed downward to squeeze the buffer plate 65, compressing the compression spring. This causes the buffer plate 65 to move downward on the second fixed rod 64 to squeeze the squeezing rod 66. The squeezing rod 66 is squeezed and deflects upward, pushing the cleaning scraper 9 to move closer to the cleaning brush 8. By controlling the electric push rod 62, the cleaning scraper 9 cleans the dirt remaining on the stirring shaft 7.

[0050] Step 3: Then, when the cleaning scraper 9 moves to one end of the stirring rod 5, the electric push rod 62 moves and the cylinder 10 is activated to retract into the stirring shaft 7, which drives the cleaning brush 8 away from the inner wall of the stirring cylinder 1 and back to its original position. At the same time, the squeezing block 12 on the cleaning scraper 9 is inserted into the squeezing groove 16 on one side of the cleaning brush 8, squeezing the squeezing ball 13, which causes the return spring 14 to compress and push the moving block 15 downward. The moving block 15 moves and drives the sealing plug away from the water outlet, so that the water in the water storage tank 17 flows into the water collection tank and then sprays the water onto the brush bristles 84 through the nozzle 19 through the water outlet pipe 18 and the water distribution pipe.

[0051] Step 4: Finally, use the rotation of the stirring rod 5 to drive the cleaning brush 8 to rotate, which in turn drives the bristles 84 to rotate, so that the dirt on the cleaning brush 8 is cleaned. Then stop the rotation of the motor 4 and discharge the fully stirred wastewater through the outlet pipe.

[0052] Working principle: During use, wastewater is poured into the mixing drum 1 through the inlet 3. The motor 4 is started, which drives the mixing rod 5 to rotate. The rotation of the mixing rod 5 drives the mixing shaft 7 to rotate, which in turn drives the cleaning brush 8 to rotate and clean the inner wall of the mixing drum 1. At the same time as the mixing rod 5 rotates, the electric push rod 62 is activated, which pushes the push plate 63 downward inside the mixing rod 5. The downward movement of the push plate 63 squeezes the buffer plate 65, compressing the compression spring. The top of the second fixed rod 64 moves into the movable cavity, causing the buffer plate 65 to move downward on the second fixed rod 64 and squeeze the squeezing rod 66. The squeezing rod 66 is squeezed and deflects upward, pushing the cleaning scraper 9 to move closer to the cleaning brush 8. By controlling the electric push rod 62, the cleaning scraper 9 moves back and forth on the mixing shaft 7 to clean the dirt remaining on the mixing shaft 7.

[0053] When cleaning brush 8 needs to be cleaned, the electric push rod 62 pushes the squeezing rod 66 to move the cleaning scraper 9 to one end of the stirring shaft 7. The cylinder 10 moves into the stirring shaft 7, causing the cleaning brush 8 to separate from the inner wall of the stirring cylinder 1 and move closer to the stirring shaft 7. At the same time, the squeezing block 12 on one side of the cleaning scraper 9 is inserted into the squeezing groove 16, causing the squeezing block 12 to squeeze the squeezing ball 13. The squeezing ball 13 compresses the return spring 14, which in turn squeezes the moving block 15 under the action of the return spring 14. This causes the moving block 15 to move the sealing plug, which then stops sealing the water outlet pipe 18 at the bottom of the water storage tank 17. This allows water inside the water storage tank 17 to flow into the water collection tank and be delivered to the nozzle 19 through the water outlet pipe 18 and the water distribution pipe. Meanwhile, the stirring rod 5 rotates, causing the stirring shaft 7 to rotate, which in turn causes the cleaning brush 8 to rotate. Water is sprayed through the nozzle 19 to rinse the bristles 84, thus cleaning the dirt on the bristles 84.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
