Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology, and in particular to an anti-clogging mechanism for a self-priming pump. Background Technology

[0002] Self-priming pumps are a type of self-priming centrifugal pump. They have advantages such as compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. No foot valve needs to be installed in the pipeline. Before operation, it is only necessary to ensure that a certain amount of priming liquid is stored in the pump body. Different materials can be used for self-priming pumps for different liquids. The working principle of a self-priming pump is that the pump casing is filled with water before the pump is started. After starting, the impeller rotates at high speed, causing the water in the impeller channel to flow to the volute. At this time, a vacuum is formed at the inlet, which opens the inlet check valve. Air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. During the operation of the self-priming pump, the liquid may contain impurities, which can easily cause blockage of the vertical self-priming pump.

[0003] Existing vertical self-priming pumps do not have the effect of preventing slag buildup. Impurities can enter the vertical self-priming pump and cause damage. Therefore, to solve the above problems, we provide a self-priming pump anti-clogging mechanism. By breaking up larger impurities and blocking them with a filter screen, we prevent impurities from entering the self-priming pump and avoid clogging. Utility Model Content

[0004] This invention provides a self-priming pump anti-clogging mechanism to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a self-priming pump anti-clogging mechanism, comprising an anti-clogging mechanism connected to the pump body's inlet end. The anti-clogging mechanism consists of a housing, a filter screen, and a crushing assembly. The lower part of the housing, facing the pump body, has an outlet connected to the pump body's inlet end, while the upper part of the housing, away from the pump body, has an inlet connected to the housing. The filter screen is located in the middle of the housing, between the outlet and the inlet. The crushing assembly consists of a motor, a rotating shaft, and a crushing blade assembly. The rotating shaft is rotatably mounted inside the housing and is coaxial with the housing's inlet. The motor is mounted on the outside of the housing and connected to the rotating shaft. The crushing blade assembly is installed at the end of the rotating shaft near the inlet.

[0006] Preferably, the filter screen is inverted V-shaped, and the bottom two sides are snapped to the two sides of the box by connectors. The top of the filter screen is fixedly connected to three connecting posts, and the connecting posts are fixedly connected to the top of the box by connectors. The rotating shaft rotates through the connecting posts located in the middle.

[0007] Preferably, a transparent observation cover is bolted to one side of the housing.

[0008] The beneficial effects of adopting the above technical solutions are:

[0009] 1. The crushing components inside the tank can crush larger impurities in the water entering from the inlet, and larger debris will be lost from the filter screen.

[0010] 2. Because the filter screen is inverted V-shaped, the two sides of the filter screen are inclined, so the water flow from top to bottom is less likely to cause blockage. The filter screen can prevent debris from entering the pump body, thereby avoiding pump blockage.

[0011] 3. The design of the observation cover on one side of the housing allows it to abut against the filter screen, limiting its position and facilitating the removal and cleaning of debris located on both sides of the filter screen. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1-2 In this embodiment, a self-priming pump anti-clogging mechanism includes an anti-clogging mechanism 2 connected to the water inlet of the pump body 1. The anti-clogging mechanism 2 is composed of a housing 21, a filter screen 22, and a crushing assembly 23. The lower part of the housing 21 facing the pump body 1 has an outlet 211 connected to the water inlet of the pump body 1, and the upper part of the housing 21 away from the pump body 1 has an inlet 212 connected to the housing 21. The filter screen 22 is located in the middle of the housing 21, between the outlet 211 and the inlet 212. The crushing assembly 23 is composed of a motor 231, a rotating shaft 232, and a crushing blade assembly 233. The rotating shaft 232 is rotatably installed inside the housing 21 and is coaxial with the water inlet 212 of the housing 21. The motor 231 is installed on the outside of the housing 21 and connected to the rotating shaft 232. The crushing blade assembly 233 is installed in the end of the rotating shaft near the water inlet 212.

[0019] With the above technical solution, when the pump body 1 is in use, the water inlet 212 of the tank 21 in the water self-anti-clogging mechanism 2 enters the tank 1. The motor 231 drives the rotating shaft 232 to drive the crushing blade assembly 233 to rotate. Thus, the impurities in the water face the crushing blade assembly 233 directly. The crushing blade assembly 233 can crush larger impurities, avoiding direct damage to the filter screen 22. The filter screen 22 can filter impurities in the water to prevent them from entering the pump body 1 and causing blockage.

[0020] Preferably, the filter screen 22 is inverted V-shaped, and the bottom two sides are connected to the two sides of the housing 21 by connectors 221. The top of the filter screen 22 is fixedly connected with three connecting posts 222, and the connecting posts 222 are fixedly connected to each other by connectors 221 that are connected to the top of the housing 1. The rotating shaft 232 rotates through the connecting posts 222 located in the middle.

[0021] With the above technical solution, the filter screen 22 is inverted V-shaped, so that water washes from top to bottom, making the surface of the filter screen 22 less prone to clogging, and allowing debris to accumulate on both sides of the filter screen 22. The filter screen 22 is easily replaced and maintained by the snap-fit ​​of the connector 221 to the housing 1. The rotating shaft 232 passes through the connecting column 222, which helps to ensure the stability of the crushing blade assembly 233.

[0022] Preferably, a transparent observation cover 24 is bolted to one side of the housing 21.

[0023] Through the above technical solution, the observation cover 24 is used to seal the box 21 and restrict the filter screen 22, so as to facilitate observation of the internal condition of the box 21 and facilitate disassembly to clean the debris inside the box 21.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
