Abstract

This utility model discloses a high-suction-lift, high-efficiency, and energy-saving self-priming pump, relating to the field of self-priming pump technology. It includes a self-priming pump body with an inlet pipe. A removal pipe is fixedly connected to the inlet end of the inlet pipe, and a removal box is fixedly installed in the middle of the removal pipe. A filter screen is fixedly installed on one side of the removal box. The filter screen is used to intercept and filter the liquid flowing through the removal pipe. A removal assembly is provided on the removal box. This utility model uses the filter screen to filter out blockages. Then, a scraper ring scrapes away the blockages along the surface of the filter screen. A cleaning assembly then removes the blockages from the scraper ring. Finally, a disc, a column, and a long slot frame drive the scraper ring back to its original position. By filtering the liquid pumped into the self-priming pump body first and removing the blockages, it avoids the accumulation of blockages in the impeller blades or the flow channels within the pump body, thus making the self-priming pump body highly efficient and energy-saving, and increasing the suction lift of the self-priming pump body.

Description

Technical Field

[0001] This utility model relates to the field of self-priming pump technology, and more specifically, to a high-suction-lift, high-efficiency, and energy-saving self-priming pump. Background Technology

[0002] A self-priming pump is a centrifugal pump that can automatically draw in liquids without the need for additional priming. Through a special structural design, it can automatically expel air from the suction pipe and establish a vacuum when starting up, thereby drawing the liquid into the pump body. Moreover, it does not require manual priming and is easy to start up, making it especially suitable for scenarios with frequent start-stop operations. Its suction lift can reach 4-8 meters (the theoretical limit under atmospheric pressure is about 10 meters), and some high-performance models can reach more than 9 meters. At the same time, it can transport clean water, sewage, oil, and mildly corrosive liquids, making it widely adaptable.

[0003] However, during the use of existing self-priming pumps, if the liquid contains solid impurities (such as mud, sand, fibers, and particles), they will accumulate between the impeller blades or in the pump body flow channel, forming a blockage. According to Bernoulli's equation, when the fluid flows in the suction pipe, the increased resistance will cause pressure loss (reduction of negative pressure), thereby weakening the pump's suction force and ultimately leading to a decrease in the suction head of the self-priming pump. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high suction head, high efficiency and energy saving self-priming pump to solve the problem that if the liquid contains solid impurities, they will accumulate between the impeller blades or in the pump body flow channel during the use of the existing self-priming pump, forming a blockage. According to Bernoulli's equation, when the fluid flows in the suction pipe, the increased resistance will cause pressure loss, thereby weakening the pump's suction force and ultimately leading to a decrease in the suction head of the self-priming pump.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-suction-lift, high-efficiency, and energy-saving self-priming pump, comprising a self-priming pump body, an inlet pipe provided on the self-priming pump body, an inlet pipe fixedly connected to the input end of the inlet pipe, an impurity removal box fixedly installed in the middle of the impurity removal pipe, a filter screen fixedly installed on one side of the impurity removal box, the filter screen being used to intercept and filter liquid flowing through the impurity removal pipe, an impurity removal component provided on the impurity removal box, the impurity removal component being used to clean the blockage on the surface of the filter screen, and a cleaning component provided on the impurity removal box, the cleaning component being used to discharge the blockage cleaned by the impurity removal component into the impurity removal box.

[0006] Preferably, the impurity removal assembly includes a scraper ring connected to an impurity removal tube. A slide rod is fixedly installed on one side of the scraper ring, and the slide rod is horizontally slidably inserted into the impurity removal box. A long slot frame is fixedly connected to the end of the slide rod away from the scraper ring. An extension plate is fixedly installed on the impurity removal box, and a first drive motor is fixedly installed on the extension plate. A disc is fixedly connected to the output end of the first drive motor, and a pin is fixedly connected to the eccentric end of the disc. The pin is slidably inserted into the long slot frame.

[0007] Preferably, the inner diameter of the scraper ring is equal to the inner diameter of the impurity removal tube, and the outer side of the scraper ring can slide along the inner wall of the impurity removal box.

[0008] Preferably, the cleaning assembly includes a cleaning frame, which is fixedly installed on the side of the impurity removal box away from the filter screen. A second drive motor is fixedly installed in the middle of the cleaning frame, and a threaded rod is fixedly connected to the output end of the second drive motor. A cleaning bucket is threaded onto the outer surface of the threaded rod. The cleaning bucket is slidably inserted into the side of the impurity removal box away from the filter screen. Symmetrical limiting rods are also fixedly installed on the inner side of the cleaning frame, and the cleaning bucket is slidably sleeved on the limiting rods.

[0009] Preferably, the diameter of the cleaning bucket is equal to the inner diameter of the scraper ring. The cleaning bucket can be moved gradually from the outside to the inside. When the cleaning bucket is at its outermost position, the side of the cleaning bucket facing the impurity removal box is flush with the side of the inner wall of the impurity removal box.

[0010] Preferably, the interior of the cleaning bucket is hollow.

[0011] Preferably, a discharge pipe is fixedly connected to the side of the impurity removal box opposite to the cleaning bucket, and a collection container is detachably threaded onto the bottom of the discharge pipe.

[0012] Preferably, the discharge pipe is a downwardly curved arc-shaped tubular structure, and the inner diameter of the discharge pipe is greater than or equal to the diameter of the cleaning bucket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention relates to a self-priming pump. Liquid pumped into the self-priming pump body via the inlet pipe first passes through a removal pipe and a removal box, and is filtered by a filter screen to remove blockages. Then, a first drive motor drives a disc to rotate, and the insert at the eccentric end of the disc slides along the long groove frame, driving the scraper ring and slide rod to slide on the removal box away from the filter screen. This allows the scraper ring to scrape away the blockages along the filter screen surface. The cleaning component then removes the blockages from the scraper ring. Finally, the disc, insert, and long groove frame drive the scraper ring back to its original position. By filtering the liquid pumped into the self-priming pump body first and removing the blockages, blockages can be prevented from accumulating in the impeller blades or pump body flow channels of the self-priming pump body. This makes the self-priming pump body highly efficient and energy-saving, and increases the suction head of the self-priming pump body.

[0015] In this invention, after the scraper ring moves the blockage out and aligns with the cleaning bucket, the second drive motor drives the threaded rod to rotate. The threaded rod drives the cleaning bucket to move linearly towards the impurity removal box along the limit rod. During this process, the cleaning bucket can push out the blockage inside the scraper ring for processing.

[0016] The blockages introduced by the cleaning bucket of this utility model can slide down from the discharge pipe into the collection container for collection. Then, the collected blockages can be removed and disposed of by twisting the collection container. Attached Figure Description

[0027] The liquid pumped into the self-priming pump body 1 through the inlet pipe 2 first passes through the impurity removal pipe 3 and the impurity removal box 4, and is filtered by the filter screen 5 to remove blockages.

By filtering the liquid pumped into the self-priming pump body 1 first and cleaning out the blockages, it is possible to avoid the blockages from accumulating in the impeller blades or the flow channel inside the pump body of the self-priming pump body 1, thereby making the self-priming pump body 1 highly efficient and energy-saving, and increasing the suction head of the self-priming pump body 1.
