Description

Technical Field

[0001] This utility model belongs to the field of centrifugal pump technology, and specifically relates to an anti-deposition centrifugal pump. Background Technology

[0002] A centrifugal pump is a mechanical device that uses the principle of centrifugal force to transport liquids. It uses a rotating impeller to introduce liquids from the pump inlet and accelerates the liquids under the action of centrifugal force before discharging them from the outlet. Its characteristics include continuous and uniform flow, stable operation, low vibration, high speed, low maintenance cost, and wide applicability.

[0003] In order to prevent the deposition of internal impurities, some existing centrifugal pumps usually need to be pre-treated by a filter device at the inlet. However, when the impurity content in the water is high, a large amount of impurities will quickly adhere to the surface of the filter device, resulting in a decrease in filtration efficiency. The device needs to be disassembled frequently for manual cleaning. This maintenance method not only significantly increases the physical exertion of the operators, but also seriously restricts the continuous operating efficiency of the centrifugal pump due to the long disassembly and assembly time, which is extremely inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anti-deposition centrifugal pump. This solves the problem mentioned in the background art that some existing centrifugal pumps, in order to prevent the deposition of internal impurities during use, usually need to install a filter device at the inlet to pre-treat the introduced water. However, when the impurity content in the water is high, a large amount of impurities will quickly adhere to the surface of the filter device, resulting in a decrease in filtration efficiency. The device needs to be disassembled frequently for manual cleaning. This maintenance method not only significantly increases the physical exertion of the operators, but also the long disassembly and assembly time seriously restricts the continuous operation efficiency of the centrifugal pump, which is extremely inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal pump for preventing sedimentation, comprising a main body mechanism, the main body mechanism including a base, a centrifugal pump fixedly connected to the top of the base, a main pipe fixedly connected to one side of the centrifugal pump, an upper bracket fixedly connected to the top of the main pipe, a lifting screw threadedly connected to the inner side of the upper bracket, a first sealing pipe rotatably connected to the outer side of the lifting screw, a main pipe fixedly connected to the outer side of the first sealing pipe, an inner frame rotatably connected to the outer side of the bottom end of the lifting screw, a filter screen fixedly connected to the inner side of the inner frame, and a filter screen fixedly connected to the bottom of the main pipe. The device has a base frame, with a working chamber fixedly connected to the bottom of the base frame. An inner plate is fixedly connected to one side of the working chamber. Several positioning screws are threaded to the bottom of the working chamber. A base plate is threaded to the outer side of the positioning screws. A storage basket is fixedly connected to the top of the base plate. A side frame is fixedly connected to one side of the working chamber. A push-in screw is threaded to the inner side of the side frame. A second sealing tube is rotatably connected to the outer side of the push-in screw. The working chamber is fixedly connected to the outer side of the second sealing tube. A sliding frame is rotatably connected to the outer side of one end of the push-in screw. A scraper is fixedly connected to one side of the sliding frame.

[0006] Preferably, a handwheel is fixedly connected to the top of the lifting screw, and an upper bracket is connected to the outward thread at one end of the lifting screw.

[0007] Preferably, a washer is movably connected to the outer side of the bottom end of the positioning screw, and the washer is located below the base plate.

[0008] Preferably, the inner panel is made of transparent acrylic material, and a working chamber is fixedly connected to the outer side of the inner panel.

[0009] Preferably, a sliding rod is slidably connected to the inner side of the sliding frame, and two sliding rods are symmetrically arranged, with a working chamber fixedly connected to both ends of the sliding rod.

[0010] Preferably, a sealing gasket is fixedly connected to one side of the top of the base plate, and the sealing gasket is located between the working chamber and the base plate.

[0012] Preferably, a spring is movably connected to the outer side of the other end of the abutting screw, and the spring is located between the side stand and the hand disc.

[0013] Compared with the prior art, the present invention provides an anti-deposition centrifugal pump, which has the following beneficial effects:

[0014] 1. This utility model, by setting a scraper, allows the main body mechanism to be mounted on the base at a predetermined position. After a period of use, by holding the handwheel and rotating the lifting screw, the inner frame and its inner filter screen are driven down from the main pipe through the bottom frame to the inside of the working chamber. The height of the inner frame and filter screen is then finely adjusted according to the transparent inner plate to the desired position. Holding the handwheel, the infeed screw is rotated, moving it until the scraper on one side of the sliding frame is fully in contact with the filter screen. Then, the lifting screw is rotated in the opposite direction, causing the inner frame and filter screen to move back to the inside of the main pipe. During the process of the inner frame and filter screen rising and resetting, the scraper scrapes the filter screen from one side. The impurities adhering to one side of the filter screen are removed by the outer wall of the screen. The cleaned impurities fall naturally into the collection basket in the working chamber. After multiple cleaning operations, the accumulation of impurities in the collection basket can be observed through the inner plate. After removing the positioning screw, the bottom plate is removed and the impurities collected in the collection basket are processed in one go. Finally, the bottom plate and collection basket are reinstalled. Through the scraping of the scraper and the collection of the collection basket, the number of times and time required for personnel to disassemble and clean the filter device when the centrifugal pump is processing water with a high impurity content can be greatly reduced. This effectively reduces the physical exertion of personnel while ensuring the continuous operating efficiency of the centrifugal pump.

[0015] 2. By setting a sealing gasket, this utility model can effectively ensure the sealing degree between the bottom plate and the working chamber after the positioning screw is installed, and reduce the degree of leakage of liquid or impurities.

[0016] 3. By setting a sliding rod, this utility model can effectively ensure the stability of the sliding frame's position during sliding and under force.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0031] In this utility model, preferably, a handwheel 6 is fixedly connected to the other end of the push screw 116, and a side bracket 115 is threadedly connected to the outside of the push screw 116, which can effectively facilitate personnel to rotate the push screw 116 without the aid of external tools.

[0032] In this utility model, preferably, a spring 7 is movably connected to the outer side of the other end of the push screw 116. The spring 7 is located between the side stand 115 and the hand plate 6. By applying force to the hand plate 6, the loosening of the push screw 116 fixed to one side of the hand plate 6 during long-term use can be reduced.

[0033] The working principle and usage process of this utility model are as follows: In use, after the main body mechanism 1 and base 101 are installed at a predetermined position, and after a period of use, the lifting screw 105 is rotated by holding the handwheel 2. This causes the inner frame 107 and its inner filter screen 108 to descend from the main pipe 103 through the bottom frame 109 to the inside of the working chamber 110. The height of the inner frame 107 and filter screen 108 is then finely adjusted to the required position according to the transparent inner plate 114. The handwheel 6 is then rotated to engage the screw 116, causing it to move until the scraper 119 on one side of the sliding frame 118 is fully in contact with the filter screen 108. Then, the lifting screw 105 is rotated in the opposite direction, causing the inner frame 107 and filter screen 108 to move back to the inside of the main pipe 103. The inner frame 107 and filter screen 108 then rise and reset. During the process, the scraper 119 scrapes the outer wall of the filter screen 108 to remove impurities adhering to one side of the filter screen 108. The cleaned impurities fall naturally into the collection basket 113 in the working chamber 110. After multiple cleaning operations, the accumulation of impurities in the collection basket 113 is observed through the inner plate 114. After removing the positioning screw 111, the bottom plate 112 is removed and the impurities collected in the collection basket 113 are processed in one go. Finally, the bottom plate 112 and the collection basket 113 are installed and reset. Through the scraping of the scraper 119 and the collection of the collection basket 113, the number of times and time required for personnel to disassemble and clean the filter device when the centrifugal pump is processing water with a high impurity content can be greatly reduced. This effectively reduces the physical exertion of personnel while ensuring the continuous operating efficiency of the centrifugal pump.
