Description

Technical Field

[0001] The present invention relates to the technical field of fluorine material axial flow pumps, and particularly to a clamping plate type fluorine material axial flow pump with a self-cleaning function. Background Art

[0002] The clamping plate type fluorine material axial flow pump is a pump made of fluorine material, mainly used for transporting strongly corrosive liquids or solutions. This pump is particularly suitable for handling acid-base solutions in industries such as chemistry, environmental protection, and pharmaceuticals. The pump adopts an axial flow design, and the fluid mainly flows along the pump shaft direction. Due to the characteristics of its impeller design, the pump usually has a high flow rate and a low head, and is suitable for occasions that require large flow rate transportation.

[0003] Although the existing clamping plate type fluorine material axial flow pump has the advantages of simple structure and convenient maintenance, there are still the following problems: during the process of transporting the solution, if the solution contains solid particles, sediment or suspended matter, it may cause blockages in parts such as the impeller, pump casing, inlet and outlet of the pump. Fixed particles will accumulate inside the pump, especially when the flow rate is low or the pump is not properly maintained, sediment is likely to form blockages. Therefore, designers usually set a filter plate at the inlet pipe of the pump to prevent impurities such as fixed particles from accumulating. When fixed particles and the like accumulate on the filter plate for a long time, the filter plate becomes blocked, causing the solution to not pass through the inlet pipe normally. As the impeller rotates idly continuously, it will seriously increase energy consumption and affect the normal operation of the pump. Summary of the Invention

[0004] In view of the problem in the prior art that the internal filter plate of the pump is blocked, resulting in the impeller unable to rotate to achieve normal pumping and drainage, affecting the normal operation of the pump and increasing the energy consumption of the equipment, a clamping plate type fluorine material axial flow pump with a self-cleaning function is proposed.

[0005] The present application provides a clamping plate type fluorine material axial flow pump with a self-cleaning function, and its purpose is: by setting a self-cleaning component, when the filter plate is blocked, as the impeller rotates, the pressure in the impeller area will continuously decrease. When the pressure decreases to a certain extent, it drives the filter plate to slide horizontally. During the sliding process, the drainage box is respectively connected to the filter chamber and the inflow chamber, and changes the flow path of the solution so that the solution flows into the drainage box. And through the drainage component, the solution entering the filter chamber flushes the impurities accumulated in front of the filter plate into the drainage box at a certain angle for collection. Once the filter plate is unblocked, the pressure at the impeller increases, and the filter plate resets, enabling the pump to operate normally.

[0006] The technical solution of the present invention is: a clamping plate type fluorine material axial flow pump with a self-cleaning function, including a pump casing, a liquid outlet pipe provided at the upper end of the pump casing, a liquid suction pipe provided on the side wall of the pump casing, and a filtering unit provided on the side wall of the liquid suction pipe for filtering solution impurities. The filtering unit includes a self-cleaning component provided on the side wall of the liquid suction pipe; The self-cleaning component includes a filter box arranged on the side wall of the liquid extraction pipe, a filter plate arranged inside the filter box for filtering impurities in the solution, a diversion box arranged on the side wall of the filter box, an intersection plate arranged on the side wall of the filter plate, a first diversion hole and a second diversion hole jointly opened on the side walls of the filter box and the diversion box, a matching hole opened on the intersection plate, a screening plate arranged inside the diversion box, the screening plate is located between the first diversion hole and the second diversion hole, the intersection plate is closely attached to the inner wall of the filter box, the front end of the filter plate for filtering is a filtering cavity, and the rear end of the filter plate for filtering is an inflow cavity; The filter plate includes a dredged state and a blocked state. When the filter plate is in the dredged state, the intersection plate closes the first diversion hole and the second diversion hole. When the filter plate is in the blocked state, the first diversion hole and the second diversion hole are in an open state, and the first diversion hole is communicated with the filtering cavity, and the second diversion hole is communicated with the inflow cavity. A motion component is installed on the side wall of the filter plate.

[0007] Further, the motion component includes limit boxes respectively arranged at the upper and lower ends of the filter box, mounting plates arranged at the upper and lower ends of the filter plate, both of the two mounting plates are slidably installed in the corresponding limit boxes, spring rods arranged on the side walls of the limit boxes, and one ends of the spring rods are fixedly connected to the side walls of the corresponding mounting plates respectively.

[0008] Further, the filtering unit further includes a diversion component, the diversion component includes a rotating rod arranged between the upper and lower side walls of the filter box, a deflector arranged on the rotating rod. When the filter plate is in the dredged state, the angle between the deflector and the filter plate is 90°. When the filter plate is in the blocked state, the angle between the deflector and the filter plate is 45°. A transmission component is installed between the deflector and the filter plate.

[0009] Further, the transmission component includes a synchronous rod arranged on the side wall of the filter plate, a transmission toothed plate arranged at one end of the synchronous rod, and a driven gear arranged on the outer wall of the upper end of the rotating rod. The transmission toothed plate is meshed with the driven gear.

[0010] Further, a pipe joint is installed at one end of the filter box away from the liquid extraction pipe. The inner end of the pipe joint is set to be arc-shaped, and the arc radius is equal to half of the length of the deflector.

[0011] Further, a bearing plate is arranged at the lower end of the pump housing. A control motor is arranged at the upper end of the bearing plate. A differential box is installed on the driving end of the control motor. A shaft seat is arranged on the bearing plate. A driving rod is arranged on the shaft seat. One end of the driving rod is fixedly connected to the output end of the differential box.

[0012] Furthermore, an impeller is provided inside the pump housing, and the axis of the impeller is fixedly connected to the driving end of the differential box, and the differential box is used to control the rotation speed of the impeller.

[0013] Furthermore, a cover plate is provided at the lower end of the drainage box, and the cover plate is used to empty the impurities in the drainage box.

[0014] Advantages of the present invention: By providing a self-cleaning component, when impurities accumulate at the front end of the filter plate and cause blockage, the filter plate can slide horizontally under the action of pressure. During the sliding process, the filter chamber is connected to the inflow chamber through the drainage box, so that the solution can flow through the drainage box to the liquid outlet pipe, avoiding the phenomenon that the solution cannot be normally pumped and drained due to the blockage of the filter plate, resulting in the idling of the impeller. It ensures that the pump does not run in an idling state for a long time, avoids the increase of the motor load and energy consumption caused by the idling of the impeller, and effectively improves the service life of the device.

[0015] By providing a drainage component, when the filter plate is blocked, the filter plate can change the angle of the deflector plate through the transmission component, so that the deflector plate deflects the solution entering the filter chamber, making the solution impact the impurities accumulated at the front end of the filter plate at a certain angle and flushing these impurities into the interior of the drainage box for collection. While ensuring the normal flow of the solution, the drainage box can collect the accumulated impurities for subsequent treatment.

[0016] By providing a movement component, after the drainage component washes away the impurities accumulated at the front end of the filter plate, when the solution can flow normally through the filter plate and the pressure at the impeller is within the normal range, the filter plate resets. At this time, the drainage box and the filter box are in a closed state, and the pump can operate normally in the initial state, and the staff can handle the impurities in the drainage box. The present invention can clean the impurities at the front end of the filter plate without disassembly, ensuring that the pump will not be blocked for a long time, resulting in the idling of the impeller, and effectively reducing the energy consumption during the operation of the device.

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0029] Example 1, referring to Figures 1-6 , which is the first embodiment of the present invention, provides a clamping plate type fluorine material axial flow pump with self-cleaning function, including a pump housing 1, a liquid outlet pipe 2 fixedly installed at the upper end of the pump housing 1, a liquid extraction pipe 3 fixedly installed on the side wall of the pump housing 1, and a filtering unit for filtering solution impurities installed on the side wall of the liquid extraction pipe 3. The filtering unit includes a self-cleaning component installed on the side wall of the liquid extraction pipe 3.

[0030] The self-cleaning component includes a filter box 4 fixedly installed on the side wall of the liquid extraction pipe 3, a filter plate 5 slidably installed inside the filter box 4 for filtering impurities in the solution, a drainage box 6 fixedly installed on the side wall of the filter box 4, an intersection plate 7 fixedly installed on the side wall of the filter plate 5, a first drainage hole 8 and a second drainage hole 9 commonly opened on the side walls of the filter box 4 and the drainage box 6, a matching hole 10 opened on the intersection plate 7, a screening plate 11 fixedly installed inside the drainage box 6, the screening plate 11 being located between the first drainage hole 8 and the second drainage hole 9, the intersection plate 7 being closely attached to the inner wall of the filter box 4, the front end of the filtering of the filter plate 5 being a filtering cavity 12, and the rear end of the filtering of the filter plate 5 being an inflow cavity 13.

[0031] The filter plate 5 includes a dredged state and a blocked state. When the filter plate 5 is in the dredged state, the intersection plate 7 closes the first drainage hole 8 and the second drainage hole 9. When the filter plate 5 is in the blocked state, the first drainage hole 8 and the second drainage hole 9 are in an open state, and the first drainage hole 8 is communicated with the filtering cavity 12, and the second drainage hole 9 is communicated with the inflow cavity 13. A motion component is installed on the side wall of the filter plate 5.

[0032] Referring to Figure 4 , the motion component includes limit boxes 14 respectively fixedly installed at the upper and lower ends of the filter box 4, mounting plates 15 fixedly installed at the upper and lower ends of the filter plate 5, both mounting plates 15 being slidably installed inside the corresponding limit boxes 14, spring rods 16 fixedly installed on the side walls of the limit boxes 14, and one ends of the spring rods 16 being fixedly connected to the side walls of the corresponding mounting plates 15. A bearing plate 23 is provided at the lower end of the pump housing 1, a control motor 24 is provided at the upper end of the bearing plate 23, a differential box 25 is installed on the driving end of the control motor 24, a shaft seat 26 is provided on the bearing plate 23, a driving rod 27 is provided on the shaft seat 26, and one end of the driving rod 27 is fixedly connected to the output end of the differential box 25. An impeller 28 is provided inside the pump housing 1, the axis of the impeller 28 being fixedly connected to the driving end of the differential box 25, and the differential box 25 being used to control the rotation speed of the impeller 28.

[0033] Specifically, the working principle of the self-cleaning component is as follows: When impurities accumulate at the front end of the filter plate 5 and cause blockage, the solution cannot pass through the filter plate 5 normally. However, as the impeller 28 rotates continuously, the pressure inside the pump housing 1 decreases continuously. Due to the blockage of the filter plate 5, the solution cannot compensate for the pressure inside the pump housing 1, resulting in a continuous decrease in the pressure inside the pump housing 1. When the pressure drops to a certain value, the filter plate 5 slides along the inner wall of the filter box 4 towards the direction close to the pump housing 1 under the action of the pressure. During the sliding process of the filter plate 5, the cross plate 7 fixedly installed at one end thereof moves synchronously with the filter plate 5. During the movement process, the first drainage hole 8 and the second drainage hole 9 are in an open state. At this time, the filter chamber 12 and the inflow chamber 13 are in communication through the drainage box 6. At this time, the solution in the filter chamber 12 flows into the inflow chamber 13 through the sieve plate 11 in the drainage box 6 under the action of a strong suction force, and flows into the liquid outlet pipe 2 through the inflow chamber 13.

[0034] The self-cleaning component is the first step in cleaning the filter plate 5, that is, to ensure the normal pumping and discharging of the pump, prevent the filter plate 5 from being blocked and causing the impeller 28 to rotate idly, prevent the control motor 24 from being overloaded, effectively reduce the energy consumption of the control motor 24, and ensure the high efficiency and energy saving of the pump. At the same time, by setting the movement component, once the impurities at the front end of the filter plate 5 are dredged, it can be reset under the action of the elastic force of the spring rod 16. After the filter plate 5 is reset, the filter plate 5 returns to the dredged state again. Due to the reset of the cross plate 7, the drainage box 6 and the filter box 4 are re-sealed and not in communication.

[0035] During use, when the filter plate 5 is in a dredged state, the solution can directly pass through the filter plate 5 and enter the liquid outlet pipe 2 through the impeller 28 and flow to the designated position. When the filter plate 5 is blocked, the solution cannot pass through the filter plate 5 normally. As the impeller 28 continues to rotate, the pressure inside the pump housing 1 decreases continuously. When the pressure decreases to a certain value, the pressure overcomes the elastic force of the spring rod 16 and drives the filter plate 5 to slide horizontally.

[0036] When the filter plate 5 slides horizontally, the cross plate 7 on one side thereof moves synchronously, and during the movement process, the first drainage hole 8 and the second drainage hole 9 are in an open state through the matching hole 10. The first drainage hole 8 is communicated with the filter chamber 12, and the second drainage hole 9 is communicated with the inflow chamber 13. When the filter chamber 12 and the inflow chamber 13 are connected through the drainage box 6, the solution at the front end of the filter plate 5 will flow into the interior of the drainage box 6 under the action of the pressure and flow into the interior of the inflow chamber 13 through the drainage box 6 to realize the circulation of the solution, avoiding the increase in the energy consumption of the control motor 24 caused by the long-term idle rotation of the impeller 28.

[0037] Example 2, refer to Figures 7-10, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the filtering unit further includes a drainage component. The drainage component includes a rotating rod 17 rotatably installed between the upper and lower side walls of the filter box 4, and a deflecting plate 18 fixedly installed on the rotating rod 17. When the filter plate 5 is in a dredged state, the angle between the deflecting plate 18 and the filter plate 5 is 90°. When the filter plate 5 is in a blocked state, the angle between the deflecting plate 18 and the filter plate 5 is 45°. A transmission component is installed between the deflecting plate 18 and the filter plate 5. The transmission component includes a synchronous rod 19 fixedly installed on the side wall of the filter plate 5, a transmission toothed plate 20 fixedly installed at one end of the synchronous rod 19, and a driven gear 21 fixedly installed on the outer wall of the upper end of the rotating rod 17. The transmission toothed plate 20 meshes with the driven gear 21. A pipe joint 22 is installed at one end of the filter box 4 away from the liquid extraction pipe 3. The inner end of the pipe joint 22 is set to be arc-shaped 30, and the arc radius is equal to half of the length of the deflecting plate 18.

[0038] Specifically, the drainage component is the second step of the cleaning unit. The function of the drainage component is: when the filter plate 5 is blocked, by changing the angle of the solution entering the filter chamber 12, when the solution is sucked into the inflow chamber 13 under a large pressure, it can wash the impurities at the front end of the filter plate 5 at a certain angle. When the solution enters the inside of the inflow chamber 13 through the drainage box 6, it can bring the accumulated impurities into the inside of the drainage box 6 to dredge the filter plate 5. Once the flowing solution flushes the impurities into the inside of the drainage box 6, the pressure on the filter plate 5 decreases. At this time, the filter plate 5 can be reset, and at this time, the pump can normally suck and discharge the solution through the filter plate 5.

[0039] Under normal conditions, the angle between the deflecting plate 18 and the filter plate 5 is 90°, so that when the filter plate 5 is in a dredged state, the deflecting plate 18 has no influence on the inflow of the solution. When the filter plate 5 is blocked in a large area and causes its own displacement, the deflecting plate 18 deflects by 45° through the transmission component, so that the deflecting plate 18 changes the flow direction of the solution entering the filter box 4, so that the solution acts directly on the impurities at the front end of the filter plate 5 at a certain angle, and flushes these accumulated impurities directly into the inside of the drainage box 6 for collection. Once the filtration of the impurities at the front end of the filter plate 5 is completed, the filter plate 5 will drive the deflecting plate 18 to reset synchronously during the reset process, thereby ensuring the normal operation of the pump. While realizing the cleaning and dredging of the impurities at the front end of the filter plate 5 in the pump, the situation of shutdown will not occur, effectively improving the energy saving of the device and at the same time improving the pumping and discharging efficiency of the pump.

[0040] During use, when the filter plate 5 is in a dredged state, the filter plate 5 is in its initial position, and the angle between the diverter plate 18 and the filter plate 5 is 90°, which will not affect the normal pumping and discharging of the solution in the pump. When the filter plate 5 is in a blocked state, the filter plate 5 slides horizontally. During the sliding process, the synchronous rod 19 on the side wall is driven to move synchronously. During the movement of the synchronous rod 19, the transmission gear plate 20 at one end is driven to rotate. During the rotation of the transmission gear plate 20, the diverter plate 18 is driven to rotate 45° through the rotating rod 17. At this time, the solution entering through the pipe joint 22 impacts directly on the impurities at the front end of the filter plate 5 under the action of the diverter plate 18, and the impurities are flushed into the drainage box 6 for collection.

[0041] The remaining structure is the same as that of Embodiment 1.

[0042] Embodiment 3, referring to Figure 3 , is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a cover plate 29 is provided at the lower end of the drainage box 6, and the cover plate 29 is used to empty the impurities in the drainage box 6. The cover plate 29 at the lower end of the drainage box 6 is in a closed state under normal conditions. When the front end of the filter plate 5 is blocked and the impurities accumulated at the front end of the filter plate 5 are flushed into the drainage box 6 for collection through the drainage component, when the filter plate 5 is reset, the drainage box 6 is re-sealed through the cross plate 7. At this time, the staff can open the cover plate 29 at the lower end of the drainage box 6 to clean the impurities collected inside the drainage box 6, which is convenient for subsequent use.

[0043] The design of the drainage box 6 enables the staff to avoid disassembling and cleaning the blocked pump. The pump can dredge the blocked filter plate 5 by itself, effectively reducing the workload and work difficulty of the staff and improving the efficiency of pump maintenance.

[0044] The remaining structure is the same as that of Embodiment 2.

[0045] Combining Embodiments 1-3, the working principle of the present invention is as follows: When the filter plate 5 is in a dredged state, the solution can directly pass through the filter plate 5 and enter the liquid outlet pipe 2 through the impeller 28 and flow to the designated position. When the filter plate 5 is blocked, the solution cannot normally pass through the filter plate 5. As the impeller 28 continues to rotate, the pressure inside the pump housing 1 continuously decreases. When the solution entering the impeller 28 cannot make up for the change in the internal pressure reduction, the pressure difference between the inflow chamber 13 and the filter chamber 12 will become larger and larger. When the pressure difference reaches a certain value and gradually becomes larger, it will drive the filter plate 5 to slide horizontally.

[0046] When the filter plate 5 slides in the horizontal direction, the cross plate 7 on one side thereof moves synchronously, and during the movement, the first drainage hole 8 and the second drainage hole 9 are in an open state through the matching hole 10. The first drainage hole 8 communicates with the filtering cavity 12, and the second drainage hole 9 communicates with the inflow cavity 13. When the filtering cavity 12 and the inflow cavity 13 are connected through the drainage box 6, the solution at the front end of the filter plate 5 will flow into the interior of the drainage box 6 under the action of pressure and flow into the inflow cavity 13 through the drainage box 6 to realize the circulation of the solution, avoiding the increase in the energy consumption of the control motor 24 caused by the long-term idling of the impeller 28.

[0047] When the filter plate 5 slides along the horizontal direction, the filter plate 5 drives the synchronous rod 19 on the side wall to move synchronously, and drives the driven gear 21 to rotate through the transmission rack 20 at one end of the synchronous rod 19. When the driven gear 21 rotates, it drives the deflector plate 18 on the rotating rod 17 to rotate by 45°. At this time, the solution entering the filtering cavity 12 impacts the impurities at the front end of the filter plate 5 at a certain angle under the action of the deflector plate 18 and flushes these impurities into the interior of the drainage box 6. When the filter plate 5 completes the dredging, the filter plate 5 resets. At this time, the drainage box 6 resets under the action of the cross plate 7. After resetting, the drainage box 6 is in a closed state again. The staff can regularly open the drainage box 6 to clean the impurities collected inside regularly.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
