Description

Technical Field

[0001] This utility model belongs to the field of plunger pump technology, and in particular relates to a cooling and lubrication water circulation device for a plunger pump. Background Technology

[0002] A cooling and lubrication water circulation device for a plunger pump is a device specifically designed for plunger pumps. It constructs a water circulation system to carry away the heat generated by the plunger pump during operation, thereby achieving a cooling function. At the same time, it provides lubrication for the relevant components of the plunger pump to ensure that the plunger pump can maintain a suitable temperature during operation, reduce component wear, extend service life, and ensure its stable and efficient operation.

[0003] The existing water circulation device has an open top for the water storage tank, which allows dust to fall in easily. Over time, a large amount of impurities will accumulate in the water tank. If it is not filtered, the impurities may clog the pipes, causing poor water flow, reducing system operating efficiency, and in severe cases, even bursting the pipes, causing equipment failure, increasing maintenance costs, and leading to downtime.

[0006] This utility model is a cooling and lubrication water circulation device for a plunger pump, including a filter box, on which a filtration mechanism and a configuration mechanism are provided;

[0007] The filtration mechanism includes a motor fixedly connected to the right side of the filter box. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the filter box and is rotatably connected to the filter box. A cam is fixedly connected to the outer wall of the rotating shaft. A material inlet is opened on the back of the filter box. A coarse filter plate is rotatably connected to the inner wall of the filter box. One end of the coarse filter plate near the material inlet extends to the outside of the material inlet and is slidably connected to the material inlet. The coarse filter plate is adapted to the cam. A collection box is slidably connected to the back of the filter box. The collection box is adapted to both the coarse filter plate and the material inlet. An installation groove is opened on the front of the filter box. A fine filter plate is slidably connected to the inner wall of the installation groove.

[0008] Furthermore, a U-shaped block is fixedly connected to the front of the filter box, a slide rod is slidably connected to the U-shaped block, a pin head is fixedly connected to the bottom end of the slide rod, the bottom end of the pin head extends into the fine filter plate and is slidably connected to the fine filter plate, and a spring is wound around the outer wall of the slide rod.

[0009] Furthermore, one end of the spring is fixedly connected to the U-shaped block, and the other end of the spring is fixedly connected to the pin head.

[0010] Furthermore, the configuration mechanism includes a water storage tank located at the bottom of the filter box, a cooling tank fixedly connected to the top of the water storage tank, a liquid pump located on the right side of the filter box, a delivery pipe fixedly connected to the right side of the liquid pump, two U-shaped blocks fixedly connected to the top of the filter box, water outlet pipes fixedly connected to the two U-shaped blocks, and the end of the delivery pipe extending into the water outlet pipe.

[0011] Furthermore, the inner wall of the cooling box is provided with a cooling pipe, one end of which extends to the outside of the cooling box and is fixedly connected to the filter box. The outer wall of the cooling pipe is provided with a valve, and the other end of the cooling pipe extends to the outside of the cooling box. The other end of the cooling pipe is fixedly connected to a conveying pipe.

[0012] Furthermore, a semi-track one is fixedly connected to the top of the water storage tank, and a plunger pump is installed on the semi-track one. The end of the delivery pipe two extends into the plunger pump. Two screws are fixedly connected to the right side of the semi-track one, and a semi-track two is slidably connected to the outer wall of the two screws.

[0013] Furthermore, the outer walls of both screws are wound with springs, one end of each spring is fixedly connected to half-track one, and the other end of each spring is fixedly connected to half-track two.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a filtration mechanism, can start a liquid pump, which draws water from the storage tank and delivers it to the outlet pipe via a delivery pipe. The outlet pipe will evenly spray the water onto the coarse filter plate. During this spraying process, a motor can also be started simultaneously. The motor will drive a cam to rotate via a shaft. Due to the special shape of the cam, when it contacts the coarse filter plate, it will generate a periodic force, causing one end of the coarse filter plate to vibrate up and down, thereby filtering the water. Visible impurities in the water are intercepted by the coarse filter plate under the combined action of gravity and vibration. The filtered water is temporarily stored in the collection tank. Next, the coarsely filtered water continues to flow, passing through the fine filter plate. The fine filter plate has a finer filtration structure, capable of filtering out tiny impurities invisible to the naked eye, further improving the water's purity. If the fine filter plate needs cleaning or replacement after prolonged filtration, the sliding rod can be pulled upwards. The sliding rod will cause the pin on it to release the restriction on the fine filter plate. Afterwards, simply pull the fine filter plate outwards to easily disassemble it. This design effectively reduces the adverse effects of impurities in the water on the circulation system.

[0016] 2. This utility model, through the configuration mechanism, allows for the rotation of a turntable on the screw when the plunger pump needs to be disassembled. This turntable drives the screw to rotate, causing the second semi-track on it to move closer to the first semi-track, thereby releasing the limiting position on the plunger pump. Simultaneously, when the turntable retracts the second semi-track on the screw, the second spring on the outer wall of the screw is also compressed. The second spring stores elastic potential energy, providing power for subsequent reset operations, so that the system can quickly return to its initial limiting state after maintenance or replacement.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 As shown, this utility model is a cooling and lubrication water circulation device for a plunger pump, including a filter box 1, on which a filter mechanism 2 and a configuration mechanism 3 are provided.

[0029] The filtration mechanism 2 includes a motor 21 fixedly connected to the right side of the filter box 1. The output shaft of the motor 21 is fixedly connected to a rotating shaft 22 via a coupling. The rotating shaft 22 passes through the filter box 1 and is rotatably connected to the filter box 1. A cam 23 is fixedly connected to the outer wall of the rotating shaft 22. A material inlet 24 is opened on the back of the filter box 1. A coarse filter plate 25 is rotatably connected to the inner wall of the filter box 1. One end of the coarse filter plate 25 near the material inlet 24 extends to the outside of the material inlet 24 and is slidably connected to the material inlet 24. The coarse filter plate 25 is adapted to the cam 23. A collection box 26 is slidably connected to the back of the filter box 1. The collection box 26 is connected to the coarse filter plate. 25 and 24 are compatible. The front of the filter box 1 is provided with an installation groove 27. A fine filter plate 28 is slidably connected to the inner wall of the installation groove 27. A U-shaped block 29 is fixedly connected to the front of the filter box 1. A slide rod 291 is slidably connected to the U-shaped block 29. A pin head 292 is fixedly connected to the bottom end of the slide rod 291. The bottom end of the pin head 292 extends into the fine filter plate 28 and is slidably connected to the fine filter plate 28. A spring 293 is wound around the outer wall of the slide rod 291. One end of the spring 293 is fixedly connected to the U-shaped block 29, and the other end of the spring 293 is fixedly connected to the pin head 292.

[0030] By setting up the filtration mechanism 2, the liquid pump 33 can be started. The liquid pump 33 will draw water from the water storage tank 31 and deliver the water to the water outlet pipe 36 through the delivery pipe 34. The water outlet pipe 36 will spray the water evenly onto the coarse filter plate 25. During this spraying process, the motor 21 can also be started simultaneously. The motor 21 will drive the cam 23 to rotate through the rotating shaft 22. Due to the special shape of the cam 23, when it comes into contact with the coarse filter plate 25, it will generate a periodic force, causing one end of the coarse filter plate 25 to vibrate up and down, thereby filtering the water. Under the combined action of gravity and vibration, visible impurities in the water are intercepted by the coarse filter plate 25. The water is then filtered and temporarily stored in collection tank 26. Following this, the coarsely filtered water continues to flow, passing through fine filter plate 28. Fine filter plate 28 has a finer filtration structure, capable of filtering out tiny impurities invisible to the naked eye, further improving water purity. If fine filter plate 28 needs cleaning or replacement after prolonged filtration, the slide bar 291 can be pulled upwards. The slide bar 291 will cause the pin head 292 on it to release the restriction on fine filter plate 28. Afterwards, simply pull fine filter plate 28 outwards to easily disassemble it. This design effectively reduces the adverse effects of impurities in the water on the circulation system.

[0031] Configuration mechanism 3 includes a water storage tank 31 located at the bottom of filter box 1, a cooling box 32 fixedly connected to the top of the water storage tank 31, a liquid pump 33 located on the right side of filter box 1, a delivery pipe 34 fixedly connected to the right side of the liquid pump 33, two U-shaped blocks 35 fixedly connected to the top of filter box 1, and outlet pipes 36 fixedly connected to the two U-shaped blocks 35. The end of the delivery pipe 34 extends into the outlet pipe 36. A cooling pipe 37 is provided on the inner wall of the cooling box 32. One end of the cooling pipe 37 extends out of the cooling box 32 and is fixedly connected to the filter box 1. A valve 38 is provided on the outer wall of the cooling pipe 37. The other end of the cooling pipe 37 extends out of the cooling box 32 and is fixedly connected to the filter box 1. A second conveying pipe 39 is fixedly connected to the top of the water storage tank 31. A semi-rail 391 is fixedly connected to the top of the semi-rail 391. A plunger pump 392 is installed on the semi-rail 391. The end of the second conveying pipe 39 extends into the plunger pump 392. Two screws 393 are fixedly connected to the right side of the semi-rail 391. A second semi-rail 394 is slidably connected to the outer wall of the two screws 393. The second semi-rail 394 is adapted to the plunger pump 392. A turntable 395 is threadedly connected to the outer wall of each screw 393. A second spring 396 is wound around the outer wall of each screw 393. One end of the second spring 396 is fixedly connected to the semi-rail 391, and the other end of the second spring 396 is fixedly connected to the semi-rail 394.

[0032] By setting the configuration mechanism 3, when it is necessary to disassemble the plunger pump 392, the turntable 395 on the screw 393 can be rotated, so that the turntable 395 can drive the screw 393 to rotate, thereby causing the second half track 394 on it to move closer to the first half track 391, thereby releasing the limit on the plunger pump 392. At the same time, when the turntable 395 is used to retract the second half track 394 on the screw 393, the second spring 396 on the outer wall of the screw 393 will also be compressed synchronously. The second spring 396 will store elastic potential energy to provide power for the subsequent reset operation, so that after the maintenance or replacement operation is completed, the system can quickly return to the initial limit state.

[0033] A specific application of this embodiment is as follows: During use, the liquid pump 33 can be started, drawing water from the water storage tank 31 and delivering it to the outlet pipe 36 via the delivery pipe 34. The outlet pipe 36 will then evenly spray the water onto the coarse filter plate 25. During this spraying process, the motor 21 can also be started simultaneously. The motor 21 will drive the cam 23 to rotate via the rotating shaft 22. Due to the special shape of the cam 23, a periodic force is generated when it contacts the coarse filter plate 25, causing one end of the coarse filter plate 25 to vibrate up and down. This filters the water, allowing visible impurities in the water to be blocked by the coarse filter plate 25 under the combined action of gravity and vibration. The coarsely filtered water is temporarily stored in collection tank 26. Next, the water continues to flow, passing through fine filter plate 28. Fine filter plate 28 has a finer filtration structure, capable of filtering out tiny impurities invisible to the naked eye, further improving water purity. If fine filter plate 28 needs cleaning or replacement after prolonged filtration, the slide rod 291 can be pulled upwards. The slide rod 291 will cause the pin head 292 on it to release the restriction on fine filter plate 28. Then, simply pull fine filter plate 28 outwards to easily disassemble it. Simultaneously, during the upward pulling of slide rod 291, slide rod 291 will also cooperate with U-shaped blocks. The spring 293 on the outer wall of the spring 293 is compressed by the pin 292 and the plug head 292, allowing the spring 293 to accumulate elastic potential energy and provide power support for subsequent reset operations. This setting can effectively reduce the adverse effects of impurities in the water on the circulation system. The water filtered by the fine filter plate 28 can enter the cooling tank 32 through the cooling pipe 37 for cooling. At the same time, the cooling pipe 37 is equipped with a valve 38. By adjusting the valve 38, the water flow rate can be precisely controlled, thereby regulating the cooling effect and the operating efficiency of the entire system. The cooled water can then be transported to the plunger pump 392 through the delivery pipe 39 until it overflows from the plunger pump 392 and returns to the water storage tank 31, repeating this process. This process allows for the recycling of cooling water. When the plunger pump 392 needs to be disassembled, the turntable 395 on the screw 393 can be rotated, causing the turntable 395 to drive the screw 393 to rotate, thereby allowing the second half-track 394 on it to move closer to the first half-track 391. This releases the limit on the plunger pump 392. At the same time, when the turntable 395 retracts the second half-track 394 on the screw 393, the second spring 396 on the outer wall of the screw 393 will also be compressed. The second spring 396 will store elastic potential energy to provide power for the subsequent reset operation, so that the system can quickly return to the initial limit state after the maintenance or replacement operation is completed.
