Description

Technical Field

[0001] This invention relates to the field of centrifugal pump technology, and more particularly to an anti-clogging vertical centrifugal pump. Background Technology

[0002] The vertical multistage centrifugal pump, also known as the CDLF vertical multistage centrifugal pump, is a non-self-priming vertical multistage centrifugal pump designed and manufactured by incorporating advanced technologies from both domestic and international sources. It employs a standard vertical motor and a quick-install mechanical seal, making replacement very convenient. All flow parts of the pump are made of stainless steel (304 / 316), making it suitable for mildly corrosive media. It can replace similar products from abroad, such as CR and CRN. Since its market launch, the product has gained popularity due to its high efficiency, energy saving, reliable quality, and wide range of applications.

[0003] Existing vertical multistage centrifugal pumps still have the following drawbacks in use:

[0004] 1. During use, the extracted liquid may contain impurities, which are difficult to clean from inside the device and can easily damage the device.

[0005] 2. When the device is in use, it will vibrate to a certain extent. Vibration will generate noise and reduce the service life of the device.

[0006] To address the above problems, this invention proposes an anti-clogging vertical centrifugal pump. Summary of the Invention

[0007] This invention provides an anti-clogging vertical centrifugal pump, which solves the problems of existing technology where the pumped liquid easily contains impurities, which are difficult to clean inside the device and can easily lead to device damage. The device also vibrates to a certain extent during use, which generates noise and reduces the service life of the device.

[0008] This invention provides the following technical solution:

[0009] A clog-resistant vertical centrifugal pump includes a pump body, a water inlet and a drain outlet on the pump body, the pump body being mounted on a frame, and an air inlet on the pump body. The air inlet is detachably connected to a compressed air heater, the compressed air heater including a ceramic diaphragm heating element, the compressed air heater including an air inlet pipe and an air outlet pipe, the air outlet pipe being connected to the air inlet of the pump body via a connecting pipe.

[0010] One end of the pump body is provided with an inlet pipe, and a fixing plate is fixedly connected inside the inlet pipe. The fixing plate has an inlet hole inside. A filter mechanism is provided on one side of the inlet pipe. The filter mechanism includes a filter tube. One end of the inlet pipe is fixedly connected to the filter tube. A fixing tube is fixedly connected inside the filter tube. A circular through hole is opened inside the fixing tube. Arc-shaped grooves connected to the circular through hole are opened on both sides of the fixing tube. A filter assembly for filtering impurities is provided inside the filter tube.

[0011] The bottom of the filter tube is provided with a discharge port, and the inside of the filter tube is provided with a first L-shaped groove. The inside of the first L-shaped groove is provided with a sealing component for sealing the discharge port.

[0012] The bottom four corners of the frame are all fixedly connected with shock-absorbing mechanisms.

[0013] In one possible design, the connecting pipe is provided with a connecting part, the connecting part including a first connecting sleeve and a second connecting sleeve, the inner wall of the first connecting sleeve and the outer wall of one end of the second connecting sleeve are connected by threads, and a first sealing ring is provided between the inner wall of the first connecting sleeve and the second connecting sleeve, and the connecting pipe is connected to an air outlet pipe or an air inlet through the other end of the second connecting sleeve.

[0014] In one possible design, the compressed air heater is equipped with a pressure gauge and a temperature measuring device, and the drain outlet is connected to a drain pipe. After the hot air dries the inside of the pump body, it enters the drain pipe through the drain outlet and is then discharged from the outlet of the drain pipe.

[0015] In one possible design, the filter assembly includes a filter screen slidably connected inside the filter tube. A single circular rod is fixedly inserted through the interior of the filter screen. A second block is fixedly connected to one end of the circular rod, which engages with a circular through-hole. A frustum block is fixedly connected to the other end of the circular rod. A first block is fixedly connected to one side of the frustum block, which engages with an inlet hole. Water enters through one end of the filter tube, pushing the second block to move laterally. The second block then moves the circular rod laterally, which in turn moves the frustum block and the first block laterally. At this point, the first block no longer blocks the inlet hole, and water can sequentially enter the interior of the inlet tube through the arc-shaped groove, the circular through-hole, and the inlet hole. The filter screen can then filter out internal impurities, preventing pump blockage.

[0016] In one possible design, the filter assembly further includes two slide rods fixedly connected to one side of the filter screen and symmetrically arranged. Two slide grooves are symmetrically arranged on one side of the fixed tube. The slide grooves are slidably connected to the slide rods. One end of the slide rod is fixedly connected to the same first tension spring between it and the inner wall of one side of the slide groove.

[0017] In one possible design, the sealing assembly includes a receiving cavity formed on the inner wall of one side of the discharge port. The receiving cavity is connected to a first L-shaped groove. A horizontal plate is slidably connected to the inner wall of the first L-shaped groove. A vertical plate is fixedly connected to one end of the horizontal plate. A second tension spring is fixedly connected between one side of the vertical plate and one side of the inner wall of the first L-shaped groove. A third blocking block is fixedly connected to one end of the horizontal plate. The third blocking block works in conjunction with the discharge port. After the device rebounds, the filter pushes the impurities to the top of the discharge port. At the same time, the locking rod is no longer engaged with the locking groove, the sliding rod pushes the vertical plate back to its original position, the discharge port is opened, and the impurities are discharged through the discharge port, reducing the workload of the workers.

[0018] In one possible design, the filter tube has a second L-shaped groove inside. A sliding plate is slidably connected between the inner walls of the two sides of the second L-shaped groove. Two symmetrically arranged springs are fixedly connected between the bottom of the sliding plate and the bottom inner wall of the second L-shaped groove. A protrusion is fixedly connected to the top of the sliding plate. The top of the protrusion extends into the interior of the filter tube and works with the filter screen. The filter screen pushes the protrusion to move vertically downward. The protrusion drives the sliding plate to move vertically downward. The sliding plate drives the locking rod to move vertically downward and compress the spring. At this time, the locking rod moves from the interior of the second L-shaped groove to the interior of the positioning groove. The locking rod engages with the locking groove, further improving the stability of the third block.

[0019] In one possible design, a positioning groove is provided on the inner wall of the other side of the discharge port. A locking rod is fixedly connected to the bottom of the sliding plate, and the bottom of the locking rod extends into the interior of the positioning groove. A protruding rod is fixedly connected to one side of the third block, and a locking groove is provided on the top of the protruding rod to engage with the locking rod. The protruding rod works in conjunction with the positioning groove. At the same time, the filter screen drives the sliding rod to move laterally and stretches the first tension spring. When the water intake stops, it can help the filter screen to reset. The sliding rod located below no longer resists the vertical plate. Under the tension of the second tension spring, the vertical plate and the horizontal plate move laterally towards the filter screen. The horizontal plate blocks the discharge port and drives the protruding rod to move laterally. The protruding rod enters the interior of the positioning groove, which ensures that water will not leak out.

[0020] In one possible design, the shock absorption mechanism includes a sleeve and a fixed base plate. An inner rod is fixedly connected to the top of the fixed base plate, and the sleeve is fixedly connected to the bottom of the frame. The top of the inner rod slides through the interior of the sleeve, and a damper is provided at the top of the inner rod. A rubber pad is fixedly connected to the top of the fixed base plate. The rubber pad works in conjunction with the sleeve. When the device vibrates, the frame will drive the sleeve to move vertically downward, and the sleeve will squeeze the damper to achieve the shock absorption effect. At the same time, the rubber pad can also reduce noise and is easy to use.

[0021] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0022] In this invention, water enters through one end of the filter tube, and the water pushes the second block to move laterally. The second block drives the round rod to move laterally, and the round rod drives the frustum block and the first block to move laterally. At this time, the first block no longer blocks the liquid inlet hole, and water can enter the interior of the liquid inlet pipe in sequence through the arc groove, the circular through hole and the liquid inlet hole. At this time, the filter screen can filter the impurities inside and prevent the pump body from being blocked.

[0023] In this invention, the filter screen simultaneously drives the slide bar to move laterally and stretches the first tension spring. When the water intake stops, it can help the filter screen reset. The slide bar located below no longer abuts the vertical plate. The vertical plate and the horizontal plate move laterally toward the filter screen under the tension of the second tension spring. The horizontal plate blocks the discharge port and drives the convex rod to move laterally. The convex rod enters the interior of the positioning groove, which ensures that water will not leak out.

[0024] In this invention, the filter screen pushes the protrusion to move vertically downward, the protrusion drives the sliding plate to move vertically downward, the sliding plate drives the locking rod to move vertically downward and squeeze the spring. At this time, the locking rod moves from the inside of the second L-shaped groove to the inside of the positioning groove, and the locking rod engages with the locking groove, which further improves the stability of the third block.

[0025] In this invention, after the device rebounds, the filter screen pushes the impurities to the top of the discharge port. At the same time, the clamping rod is no longer engaged with the slot, the sliding rod pushes the vertical plate to reset again, the discharge port is opened, and the impurities are discharged through the discharge port, reducing the workload of workers. At the same time, when the device vibrates, the frame will drive the sleeve to move vertically downward, and the sleeve will squeeze the damper to achieve the effect of shock absorption. In addition, the rubber pad can also reduce noise and is easy to use.

[0026] In this invention, the second block moves laterally by the water inlet, and the filter screen can filter the internal impurities to avoid clogging the pump. When the water inlet stops, the first tension spring can help the filter screen reset, and the locking rod engages with the locking groove, which further improves the stability of the third block. After the device rebounds, the filter screen pushes the impurities to the top of the discharge port, and the impurities are discharged through the discharge port, reducing the workload of workers.

[0053] The working principle and usage process of this technical solution are as follows:

[0054] When in use, water enters through one end of the filter tube 61. The water pushes the second block 612 to move laterally. The second block 612 drives the round rod 66 to move laterally. The round rod 66 drives the frustum block 68 and the first block 67 to move laterally. At this time, the first block 67 no longer blocks the liquid inlet hole 23. Water can enter the interior of the liquid inlet tube 21 through the arc groove 62, the circular through hole 64 and the liquid inlet hole 23 in sequence. At this time, the filter screen 65 can filter the impurities inside and prevent the pump body 2 from being blocked.

[0055] At the same time, the filter screen 65 drives the slide bar 69 to move laterally and stretches the first tension spring 610. When the water intake stops, it can help the filter screen 65 to reset. The slide bar 69 located below no longer resists the vertical plate 617. The vertical plate 617 and the horizontal plate 616 move laterally towards the filter screen 65 under the pulling force of the second tension spring 618. The horizontal plate 616 blocks the discharge port 613 and drives the protruding rod 621 to move laterally. The protruding rod 621 enters the interior of the positioning groove 627. At this time, it can be ensured that water will not leak out.

[0056] Furthermore, the filter screen 65 pushes the protrusion 625 to move vertically downward, the protrusion 625 drives the sliding plate 614 to move vertically downward, the sliding plate 614 drives the locking rod 623 to move vertically downward and squeeze the spring 624. At this time, the locking rod 623 moves from the inside of the second L-shaped groove 626 to the inside of the positioning groove 627, and the locking rod 623 engages with the locking groove 622, which further improves the stability of the third block 615.

[0057] After the device rebounds, the filter screen 65 pushes the impurities to the top of the discharge port 613. At the same time, the locking rod 623 is no longer engaged with the locking groove 622, and the slide rod 69 pushes the vertical plate 617 to reset again. The discharge port 613 is opened, and the impurities are discharged through the discharge port 613, reducing the workload of the workers. At the same time, when the device vibrates, the frame 1 will drive the sleeve 71 to move vertically downward. The sleeve 71 will squeeze the damper 72 to achieve the effect of shock absorption. Meanwhile, the rubber pad 74 can also reduce noise and is easy to use.

[0058] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
