Description

Technical Field

[0001] The invention relates to the technical field of vacuum sewage unloading machines, in particular to a pump suction type vacuum sewage unloading machine. Background Art

[0002] The cleaning of open-air pools belongs to the category of water conservancy projects. When cleaning open-air pools, a concrete base is usually preset in the open-air pool, and a fixed pump-suction vacuum sewage unloader is installed on the concrete base. The sewage is sucked and cleaned by the pump-suction vacuum sewage unloader. The pump-suction vacuum sewage unloader is a device specially used for extracting and discharging sewage. It is mainly composed of a vacuum unit, a coiled spring cabinet suction unit, a vacuum sewage unloading pipeline system, information management equipment, control system, etc., to achieve continuous operation from the suction surface to the pressure surface, and to suck and discharge sewage. The pump-suction vacuum sewage unloader is provided with an inlet and an outlet, and a sewage suction pipe is connected to the inlet.

[0003] However, when the existing pump-suction vacuum sewage unloader is in use, although the filter screen arranged at the inlet of the sewage suction pipe can filter some solid impurities such as plastic bags, soft long impurities such as fibers and hair can enter the pump-suction vacuum sewage unloader through the filter screen. These long impurities have strong entanglement and are easy to be entangled and knotted in the internal structure of the pump body, causing the pump rotor, partition or other components to fail to operate normally, which is easy to cause them to be blocked, affecting their use effect and life. At the same time, when sucking sewage, the absorption effect of impurities on the water surface is poor, which easily causes impurities to adhere to the pool wall, affecting the sewage suction effect.

When the first rack 814 moves, the third T-shaped guide rod 802 is abutted against the end of the fourth T-shaped guide rod 806 through the moving mechanism 9, thereby pushing the fourth T-shaped guide rod 806 to move, the sixth spring 807 is compressed, and one end of the fourth T-shaped guide rod 806 is abutted against the fourth inclined surface 805, thereby pushing the movable plate 804 and the mounting plate 816 to move upward, the fifth spring 803 is compressed, and when the mounting plate 816 moves upward, the third push pin 818 slides in the sliding groove 817, thereby causing the slider 304 to move along the guide rail 303 in the direction away from the collecting tank 301.

[0046] The rotating mechanism 10 includes two symmetrically arranged third fixed blocks 1001 fixedly connected to the outer wall of the filter box 11, and the cover plate 302 is rotatably connected to the side wall of the third fixed block 1001 through a rotating rod. The side wall of the third fixed block 1001 is fixedly connected with a motor 1002, and the output end of the motor 1002 is fixed to one end of the rotating rod. When the motor 1002 is started, the rotation of the motor 1002 drives the rotation of the rotating rod and the cover plate 302, so that the cover plate 302 can be opened and the impurities in the collection tank 301 can be processed.

[0047] The moving mechanism 9 includes a third connecting block 902 fixedly connected to the top of the moving tube 820, and the side wall of the third connecting block 902 is fixedly connected to two symmetrically arranged seventh T-shaped guide rods 903, the side wall of the seventh T-shaped guide rod 903 is sleeved with an eighth spring 904, and the side wall of the seventh T-shaped guide rod 903 is sleeved with a fourth connecting block 901, and the fourth connecting block 901 is fixed to the top of the first rack 814, the top of the third connecting block 902 is fixedly connected to an iron block 906, and the top of the fourth connecting block 901 is fixedly connected There is an electromagnet 905. When the impurities in the collecting tank 301 need to be processed, the electromagnet 905 is energized first. After being energized, the electromagnet 905 attracts the iron block 906, so that the moving tube 820 slides along the side wall of the first rack 814 and disengages from the end of the fourth T-shaped guide rod 806. At the same time, the eighth spring 904 is compressed. At this time, the moving plate 804 can move downward and reset under the action of the fifth spring 803, and the second push plate 310 and the first push plate 307 can seal the collecting tank 301.

[0048] Working principle: When cleaning the open-air pool by suction, the second spherical cover 21 can sink to the bottom of the water under the action of gravity, and the first spherical cover 13 floats on the water surface under the buoyancy of the floating plate 16. At this time, the sludge on the bottom of the water can be absorbed through the second suction hole 22, and at the same time, the impurities floating on the water surface can be absorbed through the first suction hole 14. Moreover, through the suction operation of the suction hole 15, the floating objects on the water surface can be adsorbed and guided to slide along the side wall of the conical cover 17 and be absorbed by the first suction hole 14, so that the sludge and impurities on the bottom and the water surface can be absorbed synchronously. At the same time, the impurities can be prevented from adhering to the pool wall. Moreover, by inserting the external rod into the fixing ring 19, the positions of the first spherical cover 13 and the second spherical cover 21 can be moved, so that the suction efficiency is higher and the effect is better.

[0049] When sucking sewage, soft long impurities such as fibers and hair will be sucked in through the first sewage suction hole 14 and the second sewage suction hole 22, and at the same time, enter the filter box 11 through the sewage suction pipe 12, and be intercepted by the grid plate 2302 to avoid entering the pump suction type vacuum sewage unloading machine body 1 and causing blockage, thereby ensuring its use effect and life. At the same time, when sewage enters the inlet 101, it will impact the surface of the fan 205 to make it rotate, and the rotation of the fan 205 drives the support plate 202 and the first rotor 205 to rotate. The rotation of the shaft 206 drives the rotation of the disc 203. When the protrusion 204 abuts against the side wall of the first fixed block 201, the grid plate 2302 is pushed to move toward the collecting tank 301. At the same time, the rubber plate 2301 is deformed. When the protrusion 204 passes over the first fixed block 201, the grid plate 2302 can move and reset under the action of the rubber plate 2301. In this way, the grid plate 2302 can move back and forth, so that the interception efficiency of the long strip impurities is higher and the effect is better.

[0050] At the same time, when the grid plate 2302 moves toward the direction close to the collection tank 301, the fifth T-shaped guide rod 809 is driven to move synchronously. The movement of the fifth T-shaped guide rod 809 drives the movement of the second rack 815, thereby driving the gear 819 to rotate, and then driving the first rack 814 to move toward the direction close to the filter box 11. When the first rack 814 moves, the third T-shaped guide rod 802 is abutted against the end of the fourth T-shaped guide rod 806 through the moving mechanism 9, thereby pushing the fourth T-shaped guide rod 806 to move, and the sixth spring 807 is compressed, so that one end of the fourth T-shaped guide rod 806 is aligned with the fourth inclined surface. 805 abuts against each other, thereby pushing the moving plate 804 and the mounting plate 816 to move upward, and the fifth spring 803 is compressed. When the mounting plate 816 moves upward, the third pushing pin 818 slides in the sliding groove 817, so that the slider 304 moves along the guide rail 303 in a direction away from the collecting tank 301. At the same time, the first pushing pin 504 slides along the inclined plate 503 to the top of the fixed plate 502. At this time, the moving block 305, the moving cover 306 and the first pushing plate 307 move upward. At the same time, the third spring 403 is compressed. At this time, the first pushing plate 307 is separated from the top of the grid plate 2302.

[0051] When the first push pin 504 passes over the fixed plate 502, the moving block 305, the moving cover 306 and the first push plate 307 can move downward under the action of the third spring 403, and make the first push plate 307 abut against the top of the grid plate 2302. When the grid plate 2302 moves and resets, the moving plate 804 can move downward and reset under the action of the fifth spring 803, and drive the mounting plate 816 and the sliding groove 817 to move downward and reset, so as to push the slider 304 to move in the direction close to the collecting tank 301. At this time, the first push plate 307 can push and pull out the long strip impurities on the surface of the grid plate 2302. A part of the long strip impurities is in front of the first push plate 307 in the forward direction, and the other part is in the rear of the first push plate 307 in the forward direction and presses on the bottom of the first push plate 307.

[0052] When the second push pin 706 abuts against the third inclined surface 708, the first push block 704 is pushed to move downward. At the same time, the fourth spring 703 is compressed. When the first push block 704 moves downward, the second inclined surface 705 abuts against the second push plate 310, thereby pushing the second push plate 310 to move in the direction close to the first push plate 307. At the same time, the second spring 313 is compressed. At this time, the second push plate 310 can move along the first inclined surface 308 to the bottom of the first push plate 307 and form an extrusion plate with it and then continue to move. At the same time, the first push plate 307 moves upward, the first spring 314 is compressed, and Moreover, all the long strip impurities behind the first push plate 307 are pushed to the front thereof, so that the long strip impurities can be pushed into the collecting tank 301 for collection. At the same time, the long strip impurities in the collecting tank 301 can be squeezed, and the excess water is discharged through the drain pipe 311, so as to facilitate the cleaning and collection of the intercepted long strip impurities, ensure the filtering effect, and make it more convenient and quick to use. At the same time, when the first push pin 504 abuts against the inclined plate 503, the moving block 305 moves downward, and at the same time, the third spring 403 is stretched, so that the first push pin 504 can pass over the inclined plate 503, ensuring the subsequent normal cleaning;

[0053] Moreover, when cleaning is performed, when the moving block 305, the moving cover 306 and the first push plate 307 are moved, the L-shaped plate 309 is driven to move, and the cutter 602 is driven to move through the connecting plate 601. At this time, the cutter 602 can cut off the long strip impurities that are difficult to scrape off on the surface of the grille plate 2302. At this time, under the action of the water flow, the cut long strip impurities can pass through the grille plate 2302 normally, so that the cleaning effect is better, the clogging of the grille plate 2302 is avoided, and the effect of water flow is ensured. In addition, the length of the cut long strip impurities becomes shorter, which can prevent them from entering the interior of the pump suction vacuum unloading machine body 1 and causing clogging, thereby ensuring its use effect and life.

[0054] When it is necessary to process the impurities in the collecting tank 301, the electromagnet 905 is energized first. After being energized, the electromagnet 905 attracts the iron block 906, so that the moving tube 820 slides along the side wall of the first rack 814 and disengages from the end of the fourth T-shaped guide rod 806. At the same time, the eighth spring 904 is compressed. At this time, the moving plate 804 can move downward and reset under the action of the fifth spring 803, and the second push plate 310 and the first push plate 307 can seal the collecting tank 301. Then, the motor 1002 is started. The rotation of the motor 1002 drives the rotation of the rotating rod and the cover plate 302, so that the cover plate 302 can be opened, and the impurities in the collecting tank 301 can be processed, so that the processing can be carried out without stopping the machine, which is more convenient and quick to use and ensures the efficiency of sewage suction.
