Description

Technical Field

[0001] The present invention belongs to the technical field of sewage pumps, and particularly relates to a sewage pump that prevents blockage. Background Art

[0002] Sewage pumps belong to a type of centrifugal impurity pump and have various forms, such as two types: submersible and dry. The most commonly used submersible type is the QW type submersible sewage pump, and the most common dry sewage pumps are two types, such as the W type horizontal sewage pump and the WL type vertical sewage pump. They are mainly used to transport urban sewage, feces, or media containing solid particles such as fibers and paper scraps in the liquid. Usually, the temperature of the transported medium is not greater than 80°C. Since the transported medium contains fibrous substances that are prone to entanglement or clustering, the flow channels of this type of pump are prone to blockage. Once the pump is blocked, the pump cannot work properly, and even the motor may be burned out, resulting in poor sewage discharge, which has a serious impact on urban life and environmental protection. Therefore, anti-blocking performance and reliability are important factors in the quality of sewage pumps.

[0003] Existing sewage pumps mainly include parts such as a pump body, an impeller, a bearing, a sealing device, and a filter cover. Due to the relatively harsh working environment of the sewage pump, when using a conventional static filter cover for filtration, it is very easy for the filter cover to be blocked, thus affecting the normal and safe operation of the sewage pump. Moreover, when existing sewage pumps operate in water, they rely on the water temperature to cool the pump body. The immobility of the pump body causes the surrounding water temperature to increase, affecting the efficiency of heat exchange for cooling the pump body. For this reason, we have proposed a sewage pump that prevents blockage. Summary of the Invention

[0004] In order to solve the above problems, the purpose of the present invention is to provide a sewage pump that prevents blockage.

[0005] To achieve the above object, the present invention provides a sewage pump that prevents blockage, including a pump machine. The bottom of the pump machine is fixedly connected to a fixed cylinder. The bottom of the fixed cylinder is fixedly connected to an impeller housing. The bottom of the impeller housing is fixedly connected to a water inlet pipe. The output shaft of the pump machine is fixedly connected to a transmission shaft. An active bevel gear is fixedly sleeved on the outside of the transmission shaft, and the active bevel gear is located inside the fixed cylinder. A transmission push-pull assembly that is rotationally connected to the fixed cylinder is provided on one side of the active bevel gear. This transmission push-pull assembly is used to drive the pump machine and the water inlet pipe to reciprocate and shake. An inlet water filtering assembly is rotatably provided at the bottom of the fixed cylinder. This inlet water filtering assembly filters the inlet water. Push material cleaning assemblies are provided on both sides of the inlet water filtering assembly. These push material cleaning assemblies are used to push and scrape the impurities at the bottom of the water for cleaning.

[0006] Preferably, the transmission push-pull assembly includes a reciprocating lead screw rotatably connected to the fixed cylinder. One end of the reciprocating lead screw extending into the fixed cylinder is fixedly connected with a driven bevel gear, and the driving bevel gear is meshed with the driven bevel gear for transmission. An activity ring is sleeved on the outer thread of the reciprocating lead screw. Cross bars are fixedly connected to both sides of the outer part of the activity ring. One end of the cross bar away from the activity ring is fixedly connected with a slider, and a slide rail for sliding is arranged on one side of the slider.

[0007] Preferably, the water inlet and filtration assembly includes two fixing plates. A rack is fixedly connected to the bottom of the fixing plate. A filter ball is rotatably arranged at the bottom of the fixed cylinder. Two rotating shafts are fixedly connected to the outer part of the filter ball, and the rotating shafts movably penetrate through the fixed cylinder. A gear is fixedly connected to one end of the rotating shaft away from the filter ball, and the gear is meshed with the rack for transmission. A push-pull frame is fixedly connected to the outer part of the fixed cylinder. A scraping plate is fixedly connected to the bottom of the push-pull frame, and the filter ball rotates in contact with the scraping plate.

[0008] Preferably, the material pushing and cleaning assembly includes two guiding seats. A guiding frame is movably sleeved inside the guiding seat. Cleaning plates are fixedly connected to both ends of the guiding frame. A sleeve is movably sleeved on the outer part of the guiding frame. A material pushing plate is fixedly connected to the bottom of the sleeve. Side plates fixedly sleeved on the outer part of the guiding frame are arranged on both sides of the sleeve. A deflecting rod is rotatably arranged between the two side plates. An activity frame is fixedly connected to one side of the deflecting rod away from the material pushing plate, and the activity frame is movably sleeved on the outer part of the push-pull frame. A limiting seat is fixedly connected between the two side plates. A guiding rod is movably sleeved inside the limiting seat. A spring sleeved on the outer part of the guiding rod is fixedly connected to the bottom of the limiting seat. The guiding rod and the spring are fixedly connected to the bottom end of a cleaning plate, and a cross plate is fixedly connected to one side of the cleaning plate.

[0009] Preferably, a fixing seat is fixedly sleeved on the outer part of the fixed cylinder. Rotating columns are fixedly connected to both sides of the fixing seat. One end of the rotating column away from the fixing seat is rotatably connected with a support arm, and both the slide rail and the fixing plate are fixedly connected to the support arm.

[0010] Preferably, a support frame is fixedly connected to the bottom of the support arm. Two filter plates are installed on the support frame, and the cleaning plate scrapes and cleans on the surface of the filter plates.

[0011] Preferably, an impeller is arranged at one end of the transmission shaft extending into the impeller housing. A fixed shaft is fixedly connected to the bottom end of the transmission shaft, and an upper water auger is fixedly connected to the bottom end of the fixed shaft.

[0012] Preferably, a fixed pipe communicated with the impeller housing is fixedly connected to one side of the impeller housing. A hose is connected to the top end of the fixed pipe through a flange.

[0013] Preferably, a through hole is formed on one side of the fixed cylinder. A sealing bearing is sleeved inside the through hole, and the reciprocating lead screw is sleeved inside the sealing bearing.

[0014] The sewage pump with anti-blocking function proposed by the present invention can bring the following beneficial effects: The pump drives the transmission push-pull assembly to work through the transmission shaft and the driving bevel gear. When the transmission push-pull assembly is working, it will drive the entire pump, fixed cylinder, impeller housing, water inlet pipe and water inlet filtering assembly to reciprocate and shake. Such shaking of the pump helps to improve the efficiency of heat exchange and cooling, and the shaking of the water inlet filtering assembly can change the position of the water inlet, avoiding being easily blocked by impurities due to static state. The filtering balls on the water inlet filtering assembly rotate reciprocally, and the surface of the filtering balls is also scraped and cleaned by the stationary part, thus ensuring the filtering and anti-blocking effect of the filtering balls. The transmission push-pull assembly also drives the material pushing and cleaning assembly to work. The material pushing and cleaning assembly will push towards both sides, thus facilitating the pushing away of the impurities adsorbed nearby and preventing the accumulation of impurities around to affect the water inlet. In summary, the structure of this solution is simple and novel. It not only facilitates driving the pump and the water inlet filtering assembly to shake. The shaking of the pump helps to efficiently exchange heat and cool down, and the shaking of the water inlet filtering assembly can change the position of the water inlet. At the same time, it also rotates for filtering and cleaning, and pushes materials to both sides during shaking, facilitating the pushing away of impurities and being conducive to smooth water absorption.

[0030] As Figures 1 to 8 As shown, an embodiment of the present invention provides a sewage pump that prevents blockage, including a pump body 1. A fixed cylinder 2 is fixedly connected to the bottom of the pump body 1. An impeller housing 3 is fixedly connected to the bottom of the fixed cylinder 2. A water inlet pipe 4 is fixedly connected to the bottom of the impeller housing 3. A transmission shaft 5 is fixedly connected to the output shaft of the pump body 1. An active bevel gear 6 is fixedly sleeved outside the transmission shaft 5, and the active bevel gear 6 is located inside the fixed cylinder 2. A transmission push-pull assembly 7 that is rotatably connected to the fixed cylinder 2 is provided on one side of the active bevel gear 6. The transmission push-pull assembly 7 is used to drive the pump body 1 and the water inlet pipe 4 to reciprocally shake. A water inlet filtering assembly 8 is rotatably provided at the bottom of the fixed cylinder 2. The water inlet filtering assembly 8 filters the incoming water. Pushing and cleaning assemblies 9 are provided on both sides of the water inlet filtering assembly 8. The pushing and cleaning assemblies 9 are used to push and scrape the impurities at the bottom of the water.

[0031] As Figure 1 and Figure 6As shown in the figure, the transmission push-pull assembly 7 includes a reciprocating lead screw 701 rotatably connected to the fixed cylinder 2. One end of the reciprocating lead screw 701 extending into the interior of the fixed cylinder 2 is fixedly connected to a driven bevel gear 702, and the driving bevel gear 6 is in meshing transmission with the driven bevel gear 702. An activity ring 703 is sleeved on the external thread of the reciprocating lead screw 701. Two cross bars 704 are fixedly connected to both sides of the external part of the activity ring 703. One end of the cross bar 704 away from the activity ring 703 is fixedly connected to a slider 705. A slide rail 706 for sliding is provided on one side of the slider 705. The pump 1 drives the transmission shaft 5 to rotate, the transmission shaft 5 drives the driving bevel gear 6 to rotate, the driving bevel gear 6 drives the engaged driven bevel gear 702 to rotate, the driven bevel gear 702 drives the reciprocating lead screw 701 to rotate, and the rotation of the reciprocating lead screw 701 causes it to move within the activity ring 703, which drives the fixed cylinder 2 to rotate and tilt reciprocally. When the fixed cylinder 2 tilts, it drives the cross bar 704 to deflect on the slider 705, and the slider 705 also slides within the slide rail 706.

[0032] As Figure 7 shown, the water inlet filtering assembly 8 includes two fixing plates 801. A rack 802 is fixedly connected to the bottom of the fixing plate 801. A filtering ball 803 is rotatably provided at the bottom of the fixed cylinder 2. Two rotating shafts 804 are fixedly connected to the external part of the filtering ball 803, and the rotating shafts 804 movably penetrate through the fixed cylinder 2. One end of the rotating shaft 804 away from the filtering ball 803 is fixedly connected to a gear 805, and the gear 805 is in meshing transmission with the rack 802. A push-pull frame 806 is fixedly connected to the external part of the fixed cylinder 2. A scraping plate 807 is fixedly connected to the bottom of the push-pull frame 806, and the filtering ball 803 rotates in contact with the scraping plate 807. When the fixed cylinder 2 shakes, it also drives the water inlet pipe 4 to shake reciprocally. The water inlet pipe 4 drives the gear 805 to rotate along the rack 802. In this way, the gear 805 drives the filtering ball 803 to rotate through the rotating shaft 804. The rotation of the filtering ball 803 changes the position of the filtering holes. At the same time, the filtering ball 803 also scrapes and cleans on the scraping plate 807, which is beneficial to keeping the filtering ball 803 for efficient filtering.

[0033] As Figure 7 and Figure 8As shown in the figure, the material pushing and cleaning assembly 9 includes two guide seats 901. A guide frame 902 is movably sleeved inside the guide seat 901. Cleaning plates 903 are fixedly connected to both ends of the guide frame 902. A sleeve is movably sleeved outside the guide frame 902. A material pushing plate 904 is fixedly connected to the bottom of the sleeve. Side plates 905 fixedly sleeved outside the guide frame 902 are provided on both sides of the sleeve. A deflection rod 906 is rotatably provided between the two side plates 905. A movable frame 907 is fixedly connected to the side of the deflection rod 906 away from the material pushing plate 904, and the movable frame 907 is movably sleeved outside the push-pull frame 806. A limit seat 908 is fixedly connected between the two side plates 905. A guide rod 909 is movably sleeved inside the limit seat 908. A spring 910 sleeved outside the guide rod 909 is fixedly connected to the bottom of the limit seat 908. The bottom ends of the guide rod 909 and the spring 910 are fixedly connected to a cleaning plate 911. A cross plate 912 is fixedly connected to one side of the cleaning plate 911. When the water inlet pipe 4 reciprocates and shakes, it also drives the push-pull frame 806 to shake synchronously. The push-pull frame 806 drives the movable frame 907 to move. The movable frame 907 drives the deflection rod 906 to move and deflect. The deflection rod 906 also drives the side plate 905 to move. The side plate 905 drives the guide frame 902 to move horizontally. In this way, the guide frame 902 drives the material pushing plate 904 to push the material horizontally on one side, so as to push away the adsorbed impurities. When the material pushing plate 904 is pushing the material, the push-pull frame 806 squeezes the cross plate 912. The cross plate 912 moves downward when being squeezed. In this way, the cross plate 912 drives the cleaning plate 911 to move downward, and the spring 910 pulls the cleaning plate 911 to move upward and reset. In this way, the cleaning plate 911 scrapes up and down inside the material pushing plate 904 to prevent impurities from blocking in the grooves on the material pushing plate 904.

[0034] As Figure 5 and Figure 7 shown in the figure, a fixed seat 13 is fixedly sleeved outside the fixed cylinder 2. Rotating columns 19 are fixedly connected to both sides of the fixed seat 13. One end of the rotating column 19 away from the fixed seat 13 is rotatably connected to a support arm 14. Among them, both the slide rail 706 and the fixed plate 801 are fixedly connected to the support arm 14. When the fixed cylinder 2 shakes, it reciprocates and shakes on the support arm 14 by means of the rotating column 19. The slide rail 706 is fixedly connected to the support arm 14 through a connecting block.

[0035] As Figure 5 and Figure 8 shown in the figure, a support frame 15 is fixedly connected to the bottom of the support arm 14. Two filter plates 16 are installed on the support frame 15. The cleaning plate 903 scrapes and cleans on the surface of the filter plate 16. When the guide frame 902 moves, it drives the cleaning plate 903 to move horizontally synchronously. The cleaning plate 903 scrapes and cleans the surface of the filter plate 16.

[0036] As Figure 5As shown, one end of the transmission shaft 5 extending into the interior of the impeller housing 3 is provided with an impeller 10. The bottom end of the transmission shaft 5 is fixedly connected to a fixed shaft 11, and the bottom end of the fixed shaft 11 is fixedly connected to a water inlet auger 12. The pump 1 drives the transmission shaft 5 to rotate, the transmission shaft 5 drives the impeller 10 to rotate, and the impeller 10 will send water into the fixed pipe 17 and send it away. The transmission shaft 15 also drives the fixed shaft 11 to rotate, the fixed shaft 11 drives the water inlet auger 12 to rotate, and the water inlet auger 12 will convey water upward, thus ensuring the continuous and smooth water inlet.

[0037] As Figure 4 shown, one side of the impeller housing 3 is fixedly connected to a fixed pipe 17 communicating therewith. The top end of the fixed pipe 17 is connected to a hose 18 through a flange. The hose 18 will not affect the shaking of the pump 1, and water enters the hose 18 from the fixed pipe 17 and is discharged.

[0038] As Figure 1 and Figure 6 shown, a through hole is formed on one side of the fixed cylinder 2. A sealing bearing is sleeved inside the through hole, and the reciprocating lead screw 701 is sleeved inside the sealing bearing. The reciprocating lead screw 701 performs fixed-point rotation inside the sealing bearing. Working principle: When in use, the entire device is placed in water. At this time, the pump 1 works to drive the transmission shaft 5 to rotate, the transmission shaft 5 drives the impeller 10 to rotate, and the impeller 10 will send water into the fixed pipe 17 and send it away. The water enters the hose 18 from the fixed pipe 17 and is discharged. The transmission shaft 15 also drives the fixed shaft 11 to rotate, the fixed shaft 11 drives the water inlet auger 12 to rotate, and the water inlet auger 12 will convey water upward, thus ensuring the continuous and smooth water inlet. The transmission shaft 5 also drives the driving bevel gear 6 to rotate, the driving bevel gear 6 drives the driven bevel gear 702 engaged therewith to rotate, and the driven bevel gear 702 will drive the reciprocating lead screw 701 to rotate. The rotation of the reciprocating lead screw 701 will reciprocate inside the movable ring 703. In this way, the reciprocating lead screw 701 will drive the fixed cylinder 2 to perform reciprocating rotational inclination. When the fixed cylinder 2 shakes, it will reciprocate on the support arm 14 by means of the rotating column 19. When the fixed cylinder 2 shakes, it will drive the cross bar 704 to deflect on the slider 705, and the slider 705 will also slide inside the slide rail 706. In this way, the pump 1 performs reciprocating shaking, thereby improving the heat exchange and cooling efficiency of the pump 1.

[0039] When the fixed cylinder 2 shakes, it also drives the water inlet pipe 4 to shake reciprocally, thus changing the water inlet position and preventing the water inlet pipe 4 from remaining stationary and adsorbing impurities and aggregating them together. When the water inlet pipe 4 shakes, it drives the gear 805 to rotate along the rack 802. In this way, the gear 805 drives the filter ball 803 to rotate through the rotating shaft 804. The rotation of the filter ball 803 will change the position of the filter holes. At the same time, the filter ball 803 also scrapes on the scraper 807 for cleaning, which is beneficial to keep the filter ball 803 filtering efficiently. When the water inlet pipe 4 shakes reciprocally, it also drives the push-pull frame 806 to shake synchronously. The push-pull frame 806 drives the movable frame 907 to move. The movable frame 907 drives the deflecting rod 906 to move and deflect. The deflecting rod 906 also drives the side plate 905 to move. The side plate 905 drives the guide frame 902 to move horizontally. In this way, the guide frame 902 drives the push plate 904 to push the material on one horizontal side, so as to push away the adsorbed impurities. When the push plate 904 pushes the material, the push-pull frame 806 squeezes the cross plate 912. When the cross plate 912 is squeezed, it moves downward. In this way, the cross plate 912 drives the cleaning plate 911 to move downward. And the spring 910 pulls the cleaning plate 911 to move upward and reset. In this way, with the continuous squeezing of the push-pull frame 806 and the upward stretching of the spring 910, the cleaning plate 911 will scrape up and down inside the push plate 904 to prevent impurities from blocking in the grooves on the push plate 904. When the guide frame 902 moves, it drives the cleaning plate 903 to move horizontally synchronously. The cleaning plate 903 scrapes the surface of the filter plate 16 to prevent impurities from blocking the filter plate 16.
