Description

Technical Field

[0001] This utility model relates to the field of drainage pumps, and in particular to a drainage pipe joint and a drainage pump. Background Technology

[0002] A drainage pump is a device used to drain liquids from pools or storage tanks. Centrifugal pumps rely on the vacuum generated by the impeller to draw water up from below and pump it to a higher position. If there is no water in the pump body, the vacuum cannot be formed, and water cannot be drawn up. If the liquid level is higher than the pump, water can be introduced into the pump body by self-priming; otherwise, priming is required.

[0003] When existing drainage pumps discharge accumulated water, the water has been accumulating for a long time and contains a lot of impurities. If the water is discharged directly, it can easily cause pollution. Therefore, the discharged water source needs to be filtered. However, adding an extra filtration structure can easily affect efficiency.

[0004] Therefore, it is necessary to propose a drainage pipe joint and a drainage pump to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage pipe joint and a drainage pump to solve the problem that when existing drainage pumps discharge accumulated water, the water has been accumulating for a long time and contains a lot of impurities. If the water is discharged directly, it will easily cause pollution. It is necessary to filter the discharged water source. However, if an additional filtration structure is added, it will easily affect the efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drainage pipe connector, comprising a filter cylinder, one end of which is connected to a connecting pipe, a first rotating shaft rotatably connected between the two inner sides of the filter cylinder, a second rotating shaft provided on one side of the first rotating shaft, the second rotating shaft being fixed between the two inner sides of the filter cylinder, sleeves being fitted on the outer sides of the first and second rotating shafts, and grinding teeth fixed on the outer sides of both sleeves, the two grinding teeth meshing with each other;

[0007] The first and second rotating shafts are arranged in parallel, and the first and second rotating shafts and the filter cylinder are distributed at a perpendicular angle. A leakage hole is opened on the outside of the filter cylinder, and a filter screen is installed in the leakage hole.

[0008] Preferably, the end of the filter cartridge away from the connecting pipe is connected to two discharge pipes, both of which are connected to the interior of the filter cartridge.

[0009] Preferably, both discharge pipes have threaded caps on their outer sides.

[0010] This utility model also discloses a drainage pump, including a pump body shell, a support frame fixed on one side of the pump body shell, a rotating shaft rotatably connected inside the support frame, one end of the rotating shaft extending into the pump body shell, and an impeller fixed on the outer side of the end of the rotating shaft extending into the pump body shell, the impeller being rotatably disposed inside the pump body shell.

[0011] Preferably, the top of the pump housing is provided with a water inlet, and the side of the pump housing away from the support frame is provided with a drain outlet, and both the water inlet and the drain outlet are connected to the interior of the pump housing.

[0012] Preferably, one end of the connecting pipe is connected to the drain outlet.

[0013] Preferably, the other end of the rotating shaft is connected to a drive mechanism.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the actual operation of this utility model, when the water source is discharged into the filter cylinder through the drain outlet, the impact force of the water flow will drive the first rotating shaft to rotate. Since the second rotating shaft is set behind the first rotating shaft and is fixed, the grinding teeth on the second rotating shaft do not move, while the grinding teeth on the outside of the first rotating shaft rotate. The two grinding teeth mesh with each other, which can crush the impurities, reduce the generation of large impurities, and prevent large impurities from hitting the inner wall of the filter cylinder through the water flow and causing damage.

[0016] 2. Furthermore, since the impact force of the water flow is converted into the rotational force of the first rotating shaft, it can buffer the water flow and prevent the water flow from being too rapid, which would cause impurities to impact the inner wall of the filter cylinder. The impurities will be intercepted by the filter screen and remain inside the filter cylinder, while the filtered water will be discharged through the filter screen, automatically completing the separation of impurities and water.

[0017] 3. In the actual operation of this utility model, when it is necessary to clean the impurities collected inside the filter cylinder, the impurities can be poured out through the discharge pipe by opening the threaded cover. At the same time, the discharge pipe can be opened as needed to speed up the discharge speed of water. Attached Figure Description

[0022] This utility model provides, for example Figures 1-3 The drain pipe connector shown includes a filter cylinder 6, one end of which is connected to a connecting pipe 15. A water inlet 4 is provided at the top of the pump body shell 3, and a drain outlet 5 is provided on the side of the pump body shell 3 away from the support frame 1. Both the water inlet 4 and the drain outlet 5 are connected to the interior of the pump body shell 3. One end of the connecting pipe 15 is connected to the drain outlet 5.

[0023] This utility model also discloses a drainage pump, including a pump body shell 3, a support frame 1 fixed on one side of the pump body shell 3, a rotating shaft 2 rotatably connected inside the support frame 1, one end of the rotating shaft 2 extending into the pump body shell 3, and an impeller fixed on the outer side of the extended end of the rotating shaft 2, the impeller being rotatably disposed inside the pump body shell 3.

[0024] The other end of the rotating shaft 2 is connected to a drive mechanism, which can be a drive motor. When the drive motor is started, it can drive the rotating shaft 2 and the impeller to rotate. After the impeller rotates inside the pump body shell 3, it can transport the incoming water source.

[0025] The inlet 4 can be connected to a water pipe or water source to input water into the pump housing 3. The water can be discharged from the outlet 5 by the rotation of the impeller.

[0026] To address the issue that existing drainage pumps, when discharging accumulated water, often result in pollution due to the long accumulation time and the presence of numerous impurities, require filtration of the discharged water source, but adding an additional filtration structure could negatively impact efficiency, a first rotating shaft 10 is rotatably connected between the two inner sides of the filter cylinder 6. A second rotating shaft 13 is provided on one side of the first rotating shaft 10 and fixed between the two inner sides of the filter cylinder 6. Sleeves 11 are fitted around the outer sides of the first rotating shaft 10 and the second rotating shaft 13, and grinding teeth 12 are fixed to the outer sides of both sleeves 11, with the two grinding teeth 12 meshing with each other.

[0027] The first rotating shaft 10 and the second rotating shaft 13 are arranged in parallel. The first rotating shaft 10, the second rotating shaft 13 and the filter cylinder 6 are distributed at a perpendicular angle. A leakage hole 7 is opened on the outside of the filter cylinder 6, and a filter screen 14 is installed in the leakage hole 7.

[0028] In the actual operation of this utility model, when the water source is discharged into the filter cylinder 6 through the drain outlet 5, the impact force of the water flow will drive the first rotating shaft 10 to rotate. Since the second rotating shaft 13 is located behind the first rotating shaft 10 and is fixedly installed, the grinding teeth 12 on the second rotating shaft 13 do not move, while the grinding teeth 12 on the outside of the first rotating shaft 10 rotate. The two grinding teeth 12 mesh with each other, which can crush the impurities, reduce the generation of large impurities, and prevent large impurities from hitting the inner wall of the filter cylinder 6 through the water flow and causing damage.

[0029] Furthermore, since the impact force of the water flow is converted into the rotational force of the first rotating shaft 10, it can buffer the water flow and prevent the water flow from being too rapid, thus preventing impurities from impacting the inner wall of the filter cylinder 6.

[0030] Impurities will be intercepted by filter screen 14 and remain inside filter cylinder 6, while the filtered water will be discharged through filter screen 14, automatically completing the separation of impurities and water.

[0031] The end of the filter cylinder 6 away from the connecting pipe 15 is connected to two discharge pipes 8. Both discharge pipes 8 are connected to the inside of the filter cylinder 6, and both discharge pipes 8 are threaded with threaded caps 9 on the outside.

[0032] In the actual operation of this utility model, when it is necessary to clean the impurities collected inside the filter cylinder 6, the impurities can be poured out through the discharge pipe 8 by opening the threaded cover 9. At the same time, the discharge pipe 8 can be opened as needed to speed up the discharge speed of water.
