Description

Technical Field

[0001] This application relates to the field of plastic steel pumps, and more particularly to a plastic steel pump with good corrosion resistance. Background Technology

[0002] Plastic-coated steel pumps are machines used to transport or pressurize liquids. They transfer the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. They are mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] Currently, Chinese utility model patent CN221800215U discloses a corrosion-resistant centrifugal pump, including a centrifugal pump body and a filtration mechanism. The input end of the centrifugal pump body is connected to the water inlet pipe. The filtration mechanism includes a filtration component and a sludge removal component. The filtration component includes a filter plate, a filter box, and a limiting block. The end of the water inlet pipe away from the centrifugal pump body is connected to the filter box. The filter plate is slidably connected to the filter box. The sludge removal component is used to clean impurities on the filter plate and filter impurities in the water flow. This utility model has the effect of reducing the amount of impurities in the water entering the pump body.

[0004] During pump operation, water continuously enters the pump body. The sludge removal component can clean the filter plates in a short time, but impurities in the water are always inside the filter box. When there are too many impurities in the filter box, water cannot pass through the filter box smoothly, and staff still need to deal with the impurities in the filter box. When dealing with the impurities in the filter box, the pump needs to be stopped, which reduces the working efficiency. Utility Model Content

[0005] In order to reduce the amount of impurities processed in the filter box and thus improve the working efficiency of the pump, this application provides a plastic steel pump with good corrosion resistance.

[0006] This application provides a corrosion-resistant plastic steel pump, which adopts the following technical solution:

[0007] A corrosion-resistant plastic steel pump includes a pump body, a filter box, an inlet pipe, a filter screen, three push plates, and a rotating motor. The filter box is located at the input end of the pump body, and its inner wall is cylindrical. The filter screen is mounted on the filter box and is used to reduce impurities entering the input end of the pump body. The three push plates are located inside the filter box and divide the filter box into three chambers. The rotating motor is used to drive the push plates to rotate. One end of the inlet pipe is connected to the filter box. The filter box also has a discharge hole for impurities to be discharged. The filter screen, the inlet pipe, and the discharge hole are respectively located in the three chambers.

[0008] By adopting the above technical solution, after the pump body starts, water enters the filter box from the inlet pipe. This causes the water to first enter the chamber connected to the inlet pipe. Driven by the rotating motor, the chamber originally connected to the inlet pipe is rotated to connect with the pump body. At this time, the water in the chamber enters the pump body through the filter screen. Impurities are isolated by the filter screen and remain in the chamber. The rotating motor continues to rotate until the impurities in the chamber move to the discharge hole. The impurities are discharged out of the filter box through the discharge hole. The three push plates make the filter box form a small water pump, which pressurizes the water into the filter box. The filtered water then enters the pump body for pumping out. The filter box reduces the amount of impurities entering the pump body, reduces the corrosion of the pump body, and extends the service life of the pump body. The discharge hole reduces the amount of impurities remaining in the filter box, extends the equipment cleaning cycle, and improves the working efficiency of the pump body.

[0009] Optionally, the discharge port is located on the inner bottom wall of the filter box, and the push plate is inclined to guide impurities toward the discharge port.

[0010] By adopting the above technical solution, the mass of impurities in the water is relatively large, and the mass fraction of impurities is greater than that of air. Under the action of gravity, the impurities pass through the discharge hole. The inclined setting of the push plate can better move the direction of the impurity tank discharge hole.

[0011] Optionally, the filter box includes a box body, a cover body, and a sealing element. The sealing element includes a rotating ring, which is disposed on the box body. The inner sidewall of the rotating ring has a threaded groove, and the rotating ring is used to be bolted to the cover body.

[0012] By adopting the above technical solution, the filter box includes a box body and a cover. When impurities clog the filter screen, the staff can clean it in time. The staff can make the cover and the rotating ring rotate relative to each other to separate the cover from the box body for timely cleaning.

[0013] Optionally, the seal may further include a plurality of guide rods, which are disposed on the cover and are vertically arranged. The guide rods are used to pass through the cover, and the rotating ring is rotatably connected to the housing.

[0014] By adopting the above technical solution, when the inside of the box needs to be cleaned, the staff can rotate the rotating ring. The rotating ring rotates relative to the cover, and the cover moves away from the rotating ring along the guide rod until the cover is separated from the box, so that the staff can clean it in time.

[0015] Optionally, the sealing element further includes a sealing ring disposed on the housing, and a sealing groove is provided on the cover for accommodating the sealing ring.

[0016] By adopting the above technical solution, the sealing ring and the sealing groove cooperate to improve the sealing performance between the box and the cover.

[0017] Optionally, the cover is provided with an observation window for easy observation.

[0018] By adopting the above technical solution, the observation window allows staff to observe the flow of impurities inside the chamber in a timely manner, and can be dealt with promptly when the filter screen becomes clogged.

[0019] Optionally, the cover is provided with a handle.

[0020] By adopting the above technical solution, the handle makes it easier for workers to hold the cover and to align the cover with the guide rod during installation.

[0021] Optionally, the filter screen is disposed on the side wall of the housing, the water inlet pipe is disposed on the side wall of the housing, and the direction of water flow in the water inlet pipe is parallel to the tangential direction of the rotation of the push plate.

[0022] By adopting the above technical solution, the filter screen is set on the side wall of the box, which reduces the impurities from sticking to the filter screen under the action of gravity. This makes it easier for the push plate to move the impurities. The flow direction of the water in the inlet pipe is parallel to the tangential direction of the push plate rotation, so that the water flow will not resist the rotation of the push plate. On the contrary, the water flow will push the push plate to rotate, thereby reducing the output torque of the rotating motor and reducing the noise generated by the plastic steel pump.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The push plate divides the filter box into three chambers, which allow water to be fed into the filter box, water to be separated from impurities, and impurities to be discharged through different positions. Impurities will not remain in the filter box for a long time, extending the time between regular treatment of impurities in the filter box and improving the working efficiency of the equipment.

[0025] 2. The sealing element improves the sealing effect between the box and the cover. Attached Figure Description

The rotating motor 6 drives the push plate 5 to rotate. The rotation of the push plate 5 drives the water into the filter box 2. The water in the filter box 2 flows in the cavity formed by the push plate 5. When the cavity flows with the filter screen 4, the water flows into the pump body 1, and the impurities are blocked by the filter screen 4. As the push plate 5 rotates, the impurities move to the discharge hole 7 and are discharged from the filter box 2.
