Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pumps, and particularly relates to a pipeline pump assembly. Background Art

[0002] A pipeline pump can be arranged at any part of a water pipe. A pipeline pump is a kind of single-suction single-stage or multi-stage centrifugal pump, and belongs to a vertical structure. Because its inlet and outlet are on the same straight line and the inlet and outlet diameters are the same, it resembles a section of pipeline and can be installed at any position of the pipeline, so it is named a pipeline pump (also known as a booster pump).

[0003] According to the structural characteristics, the pipeline pump is a single-suction single-stage centrifugal pump, with the same inlet and outlet on the same straight line and perpendicular to the axis center line, and it is a vertical pump.

[0004] The existing pipeline pumps do not have a pretreatment function and cannot handle impurities in water. As a result, a large amount of impurities in water enter the interior of the pipeline pump, easily wind around the impeller, and thus cause damage to the impeller. For this reason, we propose a pipeline pump assembly. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline pump assembly. By setting a pretreatment mechanism, it is convenient to use a filtering component to filter impurities in water, and then use a driving component to drive a stirring component to rotate. This can not only clean the filtering component, but also break the impurities, so that they can easily pass through the filtering component and avoid the situation of blockage of the filtering component.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pipeline pump assembly includes a pipeline pump body. A pretreatment mechanism is arranged at the end of the pipeline pump body. The pretreatment mechanism includes:

[0007] A processing pipeline, which is fixedly connected to the input end of the pipeline pump body;

[0008] A filtering component, which is arranged at the end of the processing pipeline and is used for filtering impurities;

[0009] A stirring component, which is arranged outside the filtering component and is used for stirring and cleaning the outer surface of the filtering component;

[0010] A driving component, which is arranged in the middle of the stirring component and is used for driving the stirring component to rotate. An installation component is arranged between the driving component and the stirring component, and the installation component is used for connecting the stirring component and the driving component.

[0011] Preferably, the filtering component includes a fixing ring and a filter net fixedly connected to one side of the fixing ring. A connecting component is arranged between the fixing ring and the processing pipeline.

[0012] Preferably, the stirring assembly includes two cleaning rods and a plurality of crushing rods fixedly connected to the outer sides of the cleaning rods, and the outer arc contour of the cleaning rod is adapted to the outer arc contour of the filter net.

[0013] Preferably, the connecting assembly includes an annular groove opened on the end face of the processing pipeline, a connecting threaded rod fixedly connected to the inside of the annular groove, a connecting nut threadedly connected to one end of the connecting threaded rod, a sealing ring fixedly connected to one side of the fixing ring, and a connecting hole opened on the outer surface of the fixing ring, and the inside of the connecting hole is inserted with the connecting threaded rod.

[0014] Preferably, the driving assembly includes a driving motor fixedly installed on the outer surface of the processing pipeline and a rotating shaft fixedly connected to the output end of the driving motor, and one end of the rotating shaft extends to the inside of the processing pipeline.

[0015] Preferably, the mounting assembly includes a fixing block fixedly connected to the end face of the rotating shaft, a mounting threaded rod fixedly connected to the end face of the fixing block, a mounting nut threadedly connected to the outer surface of the mounting threaded rod, and a mounting ring inserted into the outer surface of the fixing block, and the side of the mounting ring is fixedly connected to one end of the corresponding cleaning rod.

[0016] The technical effects and advantages of the present utility model:

[0017] By connecting the pretreatment mechanism to the end of the pipeline pump body by means of a flange, when the pipeline pump body starts to intake water, the water will pass through the processing pipeline and thus be filtered by the filtering assembly, so as to prevent a large amount of impurities from entering the inside of the pipeline pump body and causing damage to the pipeline pump body. Subsequently, the driving assembly drives the stirring assembly to rotate, and the stirring assembly is used to scrape the impurities adhered to the filtering assembly, so as to prevent the filtering assembly from being blocked. At the same time, the scraped impurities will also be crushed by the stirring assembly, so as to facilitate passing through the filtering assembly and prevent a large amount of impurities from accumulating and causing blockage of the filtering assembly. This design can preferably preprocess the water entering the pipeline pump body, thereby protecting the pipeline pump body. BRIEF DESCRIPTION OF THE DRAWINGS

By connecting the pretreatment mechanism to the end of the pipeline pump body 7 using a flange, when the pipeline pump body 7 starts to intake water, the water will pass through the processing pipeline 1 and thus be filtered by the filtering component 2, thereby preventing a large amount of impurities from entering the interior of the pipeline pump body 7. Subsequently, the driving component 4 drives the stirring component 3 to rotate, and the stirring component 3 is used to scrape off the impurities adhering to the filtering component 2, thereby preventing the filtering component 2 from being blocked.

[0027] Furthermore, the driving assembly 4 includes a driving motor 401 fixedly installed on the outer surface of the processing pipeline 1 and a rotating shaft 402 fixedly connected to the output end of the driving motor 401, and one end of the rotating shaft 402 extends to the inner side of the processing pipeline 1; the driving motor 401 drives the rotating shaft 402 to rotate, thereby driving the stirring assembly 3 to rotate.

At this time, the stirring assembly 3 can be disassembled, and the stirring assembly 3 can be replaced to avoid the damaged stirring assembly 3 being unable to achieve good cleaning and crushing effects. During installation, the rectangular groove in the middle of the installation ring 504 is inserted into the rectangular fixing block 501, and then the installation nut 503 is reversed to connect the installation nut 503 to the installation threaded rod 502.
