Description

Technical Field

[0001] This utility model relates to the field of pump and valve processing equipment technology, and in particular to an automatic cleaning device for pumps and valves. Background Technology

[0002] A pump is a mechanical device that uses energy input to lift liquids, impart specific pressure or velocity, and transport them to higher positions, longer distances, or apply other forms of energy to the liquids. A valve, on the other hand, is a mechanical device that controls the flow rate of fluids by adjusting the cross-sectional area of ​​the flow channel, and is widely used in various fields such as industry, agriculture, and construction.

[0003] In the actual processing of pumps and valves, given that the processing equipment often contains various types of grease and the working environment is complex, centralized cleaning of pumps and valves is particularly important to avoid adverse effects on subsequent processes.

[0004] In existing technologies, centralized cleaning of pumps and valves is typically achieved using a crane and a hoisting rope. A cleaning tank is located beneath the crane, and a hanging rod is inserted into the connection hole of the pump or valve. This hanging rod, fitted onto the outside of the hoisting rope, allows the crane to change the position of the pump or valve, thus enabling immersion cleaning.

[0005] However, in existing technology devices, the cleaning process is highly dependent on manual operation, such as hanging and crane movement, which makes it difficult to accurately control the processing time, thus hindering the improvement of processing efficiency. In addition, since cranes are usually used to lift large equipment, using them only for lifting pumps and valves results in insufficient resource utilization.

[0006] In view of this, this study proposes a highly targeted and automated automatic pump and valve cleaning device to solve the above problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes an automatic pump and valve cleaning device. This device is highly targeted and automated, effectively solving the problems of significant resource waste and difficulty in quantifying processing time due to manual operation in existing technologies, thus avoiding the drawbacks of failing to effectively improve processing efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic cleaning device for a pump valve includes a pump valve with multiple connecting holes at both axial ends. A hanging rod is inserted into one of the connecting holes. The device also includes two supports arranged front and rear. A chain conveying mechanism is arranged near the two supports. The chain conveying mechanism includes a chain connected end to end. Multiple blades are equidistantly arranged between the two chain conveying mechanisms. Each blade corresponds to a link on the chain. The front and rear ends of each blade are fixedly connected to the corresponding link. Each blade has multiple through holes equidistantly arranged along the length of the blade. A driven rod is inserted into each through hole. The driven rod is located outside the chain conveying mechanism and is detachably connected to the hanging rod. A cleaning tank is arranged between the two supports. The height of the pump valve located below the chain is less than the height of the upper surface of the cleaning tank.

[0010] Preferably, the chain conveying mechanism includes a chain, a drive wheel, and a limit wheel. A drive motor is provided on one side of the drive wheel, and the output shaft of the drive motor is keyed to the drive wheel. The drive wheel is meshed with the chain for transmission. Each chain consists of an upper circulating section, a lower drive section, and two rotating sections located on the left and right sides respectively. A limit wheel is provided at the bend of each chain, and the limit wheel is rotatably connected to the bracket. The drive section has an arc-shaped structure, and the height of the middle section of the drive section is less than the height of the left and right sides of the drive section.

[0011] Preferably, a conveying mechanism is provided between the two supports, and the conveying mechanism is arranged side by side with the cleaning pool. Furthermore, the conveying mechanism and the pump valve on the left side of the support are on the same vertical plane.

[0012] Preferably, the projection of the hanging rod on the vertical plane is an S-shaped structure, the projection of the driven rod on the vertical plane is a J-shaped structure, and the upper end of the hanging rod overlaps the lower end of the driven rod at the rotation point, while the lower end of the hanging rod is inserted into the pump valve connection hole.

[0013] Preferably, the drive section of the chain is divided into a horizontal section, a cleaning section, and a separation section from left to right. When the pump valve is under the horizontal section, it moves in a straight line from left to right. When the pump valve is under the cleaning section, its height is less than the height of the upper end face of the cleaning tank. The left side of the separation section is higher than its right side. Furthermore, when the pump valve is under the separation section, its lower end face abuts against the conveying mechanism. The upper end of the hanging rod is higher than the lower end of the driven rod. The horizontal movement speed of the pump valve abutting against the conveying mechanism is greater than the horizontal movement speed of the pump valve on the left side of the conveying mechanism.

[0014] Preferably, the vertical section of the driven rod is provided with external threads, and the driven rod is screwed with two locking nuts through the external threads, and both locking nuts abut against the corresponding blades.

[0015] Compared with the prior art, the significant advantages of this utility model are as follows:

[0016] This invention employs a chain conveyor mechanism that works in conjunction with the blades and driven rod, successfully replacing the traditional suspension rope and crane system. This reduces the frequency of use of large equipment and effectively reduces energy consumption. Furthermore, the chain conveyor mechanism, through its driving function, enables the driven rod to achieve continuous cyclical movement. This design significantly enhances the controllability of processing time, thereby improving processing efficiency. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Please see Figure 1 An automatic cleaning device for pump valves is disclosed, with a structure consistent with existing technology, including a pump valve 1 to be cleaned. Specifically, the pump valve 1 shown in this device adopts a ball valve structure, with connection holes 3 on both sides for connecting to input and output pipes. In practical applications, the connection between the pump valve 1 and the input and output pipes is achieved by inserting bolts into the connection holes 3. This design not only ensures the sealing performance of the pump valve 1 but also facilitates maintenance and replacement.

[0027] It must be pointed out that in existing technical devices, the connection hole 3 at the end of the pump valve 1 is typically used. A hanging rod 2 is inserted into the connection hole 3, and a lifting rope is used to lift the rod. Then, with the help of appropriate lifting equipment (such as a crane), the lifting rope is pulled, thereby moving the pump valve 1 and adjusting its position. In actual operation, this method usually involves setting up a cleaning tank 9 below multiple pump valves 1. The cleaning tank 9 is equipped with cleaning fluid and corresponding ultrasonic or oscillation devices. The operator moves the pump valve 1 into the cleaning tank 9 using a crane, and uses the ultrasonic or oscillation device to agitate the cleaning fluid, thereby using the impact force generated during the agitation of the cleaning fluid to clean the pump valve 1. This method can effectively remove dirt and impurities from the surface of the pump valve 1, ensuring the normal operation of the pump valve 1.

[0028] Furthermore, in existing technological devices, to save costs and make effective use of existing materials, the hanging rod 2 is generally made of a thin metal strip. This design allows the operator to easily bend the hanging rod 2 into an S-shape without the need for external force, so that both ends of the hanging rod 2 can be inserted into the connecting hole 3 and the suspension rope, respectively, ensuring that the suspension rope can effectively drive the hanging rod 2.

[0029] Please see Figure 1 , Figure 2 , Figure 3 In order to save energy and reduce the frequency of use of large hoisting equipment (cranes), this device is equipped with a support 8 on the front and rear sides of the cleaning pool 9, and a chain conveyor mechanism 5 is respectively configured at the near end of the support 8.

[0030] For details, see [link to relevant documentation]. Figure 4The chain conveyor mechanism 5 consists of a chain 501 connected end to end, a drive wheel 502, and a limit wheel 503. In actual operation, the drive wheel 502 and the limit wheel 503 are in close contact with the chain 501, and the two work together to ensure that the chain 501 maintains the expected shape.

[0031] In addition, a drive motor is provided on one side of the drive wheel 502. The output shaft of the drive motor is connected to the drive wheel 502 via a key, and the drive wheel 502 is connected to the chain 501 via meshing transmission. This design enables the device to drive the chain 501 to rotate cyclically by means of the drive motor, thereby realizing continuous material conveying.

[0032] In addition, such as Figure 1 , Figure 2 As shown, both chain conveyor mechanisms 5 are equipped with corresponding drive motors, and these drive motors are all servo motors. The servo motors, with their excellent control performance, ensure precise synchronization of the two drive motors, thereby guaranteeing the synchronous operation of the chain conveyor mechanisms 5. This plays a decisive role in the uniformity and continuity of material conveying.

[0033] It should be noted that, in practical applications, to ensure the stability of the conveying position of chain 501, this device fixes the drive wheel 502 and the limit wheel 503 to the bracket 8. For example... Figure 4 Combination Figure 2 As shown, both the drive wheel 502 and the limit wheel 503 are equipped with bearings at the ends near the bracket 8. A synchronous shaft is fixedly connected to the inner ring of each bearing, and the synchronous shaft is connected to the corresponding drive wheel 502 and limit wheel 503 via a key. This method not only ensures the stability of the chain 501's position through the bearings but also reduces the frictional resistance of the chain 501 during rotation, effectively avoiding excessive frictional loss and thus extending the overall service life of the device.

[0034] Therefore, as Figure 3 As shown, this device has multiple blades 6 evenly spaced between the two chain conveying mechanisms 5. Each blade 6 corresponds one-to-one with a link on the chain 501, and the front and rear ends of each blade 6 are fixedly connected to the corresponding link. This design allows the blades 6 to rotate cyclically with the chain 501, achieving continuous material conveying.

[0035] At this point, by opening multiple through holes 11 on each blade 6 and inserting driven rods 7 into the through holes 11, the driven rods 7 are ensured to be located outside the chain conveyor mechanism 5. Utilizing the detachable connection between the driven rods 7 and the hanging rods 2, the hanging rods 2 are hung below the driven rods 7. By precisely controlling the positions of the blades 6 and the driven rods 7, this device can achieve precise control of the pump valve 1 position, thereby significantly improving the accuracy and efficiency of material conveying.

[0036] Specifically, such as Figure 5 , Figure 6 As shown, the driven rod 7 is J-shaped in vertical projection, and the bent part of the hanging rod 2 is connected to the rotating part of the driven rod 7 to realize the function of the hanging rope.

[0037] Furthermore, this device features carefully designed external threads on the vertical portion of the driven rod 7. These threads allow the driven rod 7 to be screwed onto two locking nuts 10. In practical applications, a detachable connection between the driven rod 7 and the corresponding blade 6 is achieved by restricting the two locking nuts 10 to close contact with the corresponding blade 6. Figure 3 As shown, the design allows for adjustment of the density of the driven rods 7 to match the operator's speed at which the pump valve 1 is installed. In actual operation, the operator can conveniently complete the relative installation of the pump valve 1 by utilizing the cooperation between the driven rods 7 and the hanging rods 2. Therefore, the number of hanging rods 2 matches the operator's speed at which the pump valve 1 is installed, which not only motivates the operator to improve work efficiency but also avoids stroke conflicts caused by excessively dense driven rods 7.

[0038] Furthermore, this device specifies that these through holes 11 (i.e., driven rods 7) are arranged at equal intervals along the length of the blade 6. This design fully utilizes the lateral width advantage of the device, allowing multiple operators to handle the pump valve 1 simultaneously, thereby significantly improving overall work efficiency and processing speed.

[0039] like Figure 4 , Figure 5 As shown, to ensure that pump valve 1 can smoothly slide into cleaning tank 9 under the drive of chain 501, and to avoid collisions with other components of the device during movement, the chain 501 structure is carefully designed. Specifically, the chain 501 structure consists of an upper circulation section, a lower drive section, and two rotating sections respectively located on the left and right sides. Through careful design, the drive section is limited to an arc-shaped structure, and the height of the middle section of the drive section is set lower than the height of its left and right sides. This design ensures that the height of pump valve 1 gradually decreases during its movement from left to right, thereby allowing it to be smoothly immersed in cleaning tank 9 and successfully complete the entire cleaning process.

[0040] Furthermore, this device incorporates a conveying mechanism 4 between the two supports 8, which is arranged side-by-side with the cleaning tank 9, creating a rational layout. The conveying mechanism 4 and the pump valve 1 on the left side of the support 8 are located in the same vertical plane. This design effectively utilizes the conveying mechanism 4 to realize the transfer process of the pump valve 1 after cleaning, significantly improving the convenience of subsequent operations.

[0041] like Figure 1 As shown, the conveying mechanism 4 used in this device is a belt conveyor, whose running direction is consistent with that of the chain 501, both of which can drive the pump valve 1 to achieve smooth movement from left to right. This design not only improves work efficiency but also ensures the continuity of operation.

[0042] Meanwhile, this device further refines the drive section of chain 501, dividing it into a horizontal section, a cleaning section, and a separation section from left to right. The horizontal section of chain 501 has a balanced height on both sides, ensuring that the driven rod 7 can move stably in a straight line below it. This facilitates the operator's precise positioning of the driven rod 7, allowing the hanging rod 2 to be smoothly installed on the outside of the driven rod 7.

[0043] Of particular note is that the cleaning section of chain 501 is ingeniously positioned above the cleaning tank 9 and features an arc-shaped design. This design ensures that when pump valve 1 moves to the area below the cleaning section, chain 501 can be fully immersed in the cleaning tank 9, achieving comprehensive cleaning of pump valve 1.

[0044] Furthermore, this device constrains the height of the left side of the separation section, making it greater than the height of the right side. When pump valve 1 is located below the separation section, the lower end face of pump valve 1 is in close contact with the conveying mechanism 4. Figure 5 As shown, this design ensures that when the pump valve 1 is running on the upper end of the conveying mechanism 4, the height of the upper end of the hanging rod 2 gradually exceeds the height of the lower end of the driven rod 7, thus achieving effective separation between the hanging rod 2 and the driven rod 7. At this time, the horizontal movement speed of the pump valve 1, which is constrained by the conveying mechanism 4, is greater than the horizontal movement speed of the pump valve 1 on the left side of the conveying mechanism 4, that is, the operating speed of the conveying mechanism 4 is greater than the operating speed of the chain 501, which can fully realize the separation between the hanging rod 2 and the driven rod 7. This design ensures that even if the pump valve 1 tilts forward due to its own weight, the hanging rod 2 will not be reattached to the outside of the driven rod 7.

[0045] In practical applications, such as Figure 5 As shown, the pump valve 1, which is limited by the driven rod 7, maintains a certain tilt angle due to its own weight and the unidirectional support of the hanging rod 2. Located above the conveying mechanism 4, the pump valve 1 experiences an upward supporting force from the conveying mechanism 4, and the limiting effect of the driven rod 7 disappears. Therefore, the tilt angle of the pump valve 1 gradually decreases from left to right until both its axial ends are tightly fitted with the conveying mechanism 4.

[0046] In the practical application of this utility model:

[0047] First, the operator is positioned on the left side of the device. He takes out pump valve 1 from the material box in sequence and inserts one end of the hanging rod 2 into the connection hole 3 of pump valve 1.

[0048] Next, the operator needs to choose an appropriate time to attach the other end of the hook rod 2 to the lower end of the driven rod 7 that has been moved to the side, and repeat this operation to continuously hang the pump valve 1 on the lower end of the driven rod 7.

[0049] Subsequently, the pump valve 1, which is attached to the lower end of the driven rod 7, continues to move to the right with the driven rod 7. When the pump valve 1 moves to the left side of the cleaning section, the height of the pump valve 1 gradually decreases until it is completely submerged in the cleaning tank 9.

[0050] Then, as pump valve 1 continues to move to the right, pump valve 1 moves to the right side of the cleaning section and separates from the cleaning tank 9. During this process, pump valve 1 gradually moves to the lower side of the separation section.

[0051] Finally, pump valve 1 moves from left to right on the lower side of the separation section, and its lower end face contacts the conveying mechanism 4. At the same time, the hanging rod 2 corresponding to pump valve 1 gradually disengages from the driven rod 7 until pump valve 1 is completely tilted above the conveying mechanism 4, and then is transported to the next processing stage by the conveying mechanism 4.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
