Description

Technical Field

[0001] This utility model mainly relates to the field of multi-way valve cleaning technology, specifically to a multi-way valve conveying and cleaning device. Background Technology

[0002] As a core control component of a hydraulic system, the multi-way valve has a precise internal structure, typically containing multiple interconnected oil passages and valve core holes. During machining, assembly, or remanufacturing, metal shavings, oil stains, abrasive particles, and other contaminants can easily accumulate inside the valve body and in the holes on both sides. If these residues are not thoroughly removed, they will directly lead to hydraulic system contamination, causing a series of malfunctions such as valve core jamming, seal failure, and accelerated component wear, seriously affecting the reliability and service life of the entire hydraulic system. Therefore, thoroughly cleaning the multi-way valve before leaving the factory or before assembly is a crucial procedure.

[0003] During the implementation of specific embodiments, the applicant discovered the following defects: Manual cleaning relies heavily on the experience and responsibility of operators, resulting in inconsistent cleaning rhythms and difficulty in achieving continuous batch operations, making it a bottleneck process on production lines. Furthermore, operators must repeatedly pick up and place workpieces and rinse them, leading to high labor intensity and prolonged exposure to high-pressure water vapor, posing certain safety risks. While some cleaning devices using conveyor belts to transport workpieces have emerged in the industry, simply placing them flat on the conveyor belt can damage them during transport due to rolling and collisions. More importantly, if displacement occurs, the side holes cannot be effectively aligned with the cleaning mechanism's jet stream, significantly reducing the cleaning effect.

[0004] It should be noted that the above content falls within the scope of technical knowledge of those skilled in the art. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model: This utility model provides a multi-way valve conveying and cleaning device to solve the technical problems existing in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a multi-way valve conveying and cleaning device, including a plate chain conveyor. The conveyor chain of the plate chain conveyor is equipped with limiting components for positioning cleaning baskets. Cleaning holes are evenly distributed on the bottom and surrounding side walls of the cleaning basket. A cleaning tank spans above the plate chain conveyor. Spray cleaning devices are symmetrically arranged on both sides inside the cleaning tank. A waste liquid recovery tank is located below the plate chain conveyor. During cleaning operations, the operator places the multi-way valves to be cleaned into the cleaning baskets, ensuring that the valve holes on both sides of the multi-way valves face approximately in the direction of the spray cleaning devices inside the cleaning tank. Subsequently, the cleaning baskets carrying the multi-way valves are placed one by one onto the conveyor chain of the plate chain conveyor, ensuring that the bottom of the cleaning baskets is engaged or aligned with the limiting components. The plate chain conveyor is driven by a waterproof motor, and all related materials are waterproof to ensure the normal operation of the equipment.

[0007] The plate chain conveyor is started, and the cleaning basket moves intermittently or continuously with the conveyor chain. When the cleaning basket enters the cleaning station inside the cleaning tank, the limiting device ensures its position is fixed, so that the valve orifice of the multi-way valve is exactly aligned with the nozzles on both sides. At this time, the jet cleaning device is activated, and high-pressure cleaning fluid is simultaneously sprayed from both sides onto the valve orifice and outer surface of the multi-way valve. The cleaning fluid penetrates the mesh of the cleaning basket, thoroughly cleaning the multi-way valve. Most of the waste liquid after cleaning falls into the waste liquid recovery tank below.

[0008] After cleaning, the plate chain conveyor continues to transport the cleaning basket to the unloading area at the end, where operators or robotic arms remove the cleaned multi-way valve, thus completing the entire automated cleaning process. The overall work efficiency is high, the cleaning is standardized, and good cleaning results can be achieved.

[0009] Furthermore, the cleaning box is detachably installed via connectors on both sides of the top surface of the plate chain conveyor. The connectors include L-shaped support columns fixed on the plate chain conveyor. The top of the L-shaped support column is provided with a transverse fixing hole. A transversely adjustable support column is inserted into the transverse fixing hole. A transverse support plate is connected to the end of the support column. The transverse support plate is connected to the side wall of the cleaning box by fasteners.

[0010] Furthermore, the L-shaped support column has a positioning hole at its top, and a locking bolt is threaded into the positioning hole.

[0011] Furthermore, the spray cleaning device includes vertical water pipes arranged in parallel at intervals. Multiple high-pressure nozzles are installed on the side of the vertical water pipes facing the cleaning basket. The tops of the vertical water pipes are interconnected through horizontal water pipes. A water supply connector is provided on the top of the cleaning tank. The water supply connector is connected to the horizontal water supply pipes through a water supply hose.

[0012] Furthermore, the inlet and outlet of the cleaning tank are equipped with removable shielding curtains.

[0013] Furthermore, the cleaning basket includes a metal rectangular frame, the outer side of which is woven with wire to form a mesh structure, and two snap-fit ​​blocks are symmetrically connected to the bottom of the cleaning basket, the snap-fit ​​blocks being snapped into the limiting member.

[0014] Furthermore, the limiting component includes at least two sets of L-shaped limiting blocks arranged opposite each other, the L-shaped limiting blocks together enclosing a square limiting space, a support block is provided in the middle of the square limiting space, and the support block and the L-shaped limiting blocks on both sides form a snap-fit ​​space corresponding to the snap-fit ​​block; the L-shaped limiting blocks and the support blocks are arranged at intervals on the conveyor chain plate.

[0015] Furthermore, two sets of limiting rings are symmetrically arranged on the inner side of the cleaning basket, and a concave handle is slidably connected in the limiting ring. The bottom of the concave handle is bent inward to form a limiting part.

[0016] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model is reasonably designed. It achieves automated conveying through a plate chain conveyor and, together with the spray cleaning device in the cleaning tank, enables the multi-way valve to complete efficient cleaning during the conveying process, thereby improving work efficiency, ensuring standardized cleaning, and guaranteeing stable cleaning results.

[0017] With its ingenious structural design, the cleaning tank is detachable and adjustable to meet different specifications; the cleaning basket is precisely positioned by limiting components to prevent shaking and ensure that the valve hole is aligned with the nozzle; the shielding curtain reduces the splashing of cleaning fluid, and the waste liquid recovery tank collects it centrally, which not only keeps the environment clean but also improves resource utilization.

[0018] It is easy to operate, and the concave handle of the cleaning basket is easy to put on and take off without interfering with operation; the components are easy to assemble, disassemble and adjust, which improves the practicality and adaptability of the equipment and can better meet the actual needs of multi-way valve cleaning.

[0019] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] See attached document Figure 1-5 A multi-way valve conveying and cleaning device includes a plate chain conveyor 1. Limiting components for positioning cleaning baskets 2 are provided on the conveyor chain of the plate chain conveyor 1. Cleaning holes are evenly distributed on the bottom and surrounding side walls of the cleaning baskets 2. A cleaning tank 3 spans above the plate chain conveyor 1. Spray cleaning devices 4 are symmetrically arranged on both sides inside the cleaning tank 3. A waste liquid recovery tank 5 is located below the plate chain conveyor 1. In this embodiment, during cleaning operations, the operator places the multi-way valves to be cleaned into the cleaning baskets 2, ensuring that the valve holes on both sides of the multi-way valves face approximately in the direction of the spray cleaning devices 4 inside the cleaning tank 3. Subsequently, the cleaning baskets 2 carrying the multi-way valves are placed one by one on the conveyor chain of the plate chain conveyor 1, and the bottom of the cleaning baskets 2 is engaged or aligned with the limiting components. The plate chain conveyor 1 is driven by a waterproof motor, and all related materials are waterproof to ensure the normal operation of the equipment.

[0029] Start the plate chain conveyor 1, and the cleaning basket 2 moves intermittently or continuously with the conveyor chain. When the cleaning basket 2 enters the cleaning station inside the cleaning tank 3, the limiting device ensures its position is fixed, so that the valve orifice of the multi-way valve is exactly aligned with the nozzles on both sides. At this time, the spray cleaning device 4 is activated, and high-pressure cleaning fluid is simultaneously sprayed from both sides onto the valve orifice and outer surface of the multi-way valve. The cleaning fluid penetrates the mesh of the cleaning basket 2, thoroughly cleaning the multi-way valve. Most of the waste liquid after cleaning falls into the waste liquid recovery tank 5 below.

[0030] After cleaning, the plate chain conveyor 1 continues to transport the cleaning basket 2 to the unloading area at the end, where the operator or robot arm removes the cleaned multi-way valve, thus completing the entire automated cleaning process. The overall work efficiency is high, the cleaning is standardized, and a good cleaning effect can be achieved.

[0031] The cleaning tank 3 is detachably installed via connectors on both sides of the top surface of the plate chain conveyor 1. Each connector includes an L-shaped support column 11 fixed to the plate chain conveyor 1. The top of the L-shaped support column 11 has a transverse fixing hole 12, into which a transversely adjustable support column 13 is inserted. The end of the support column 13 is connected to a transverse support plate 14, which is connected to the side wall of the cleaning tank 3 via fasteners. In this embodiment, the bottom of the L-shaped support column 11 is fixed to the two edges of the top surface of the plate chain conveyor 1 by bolts or other means. The top of the L-shaped support column 11 has a transverse fixing hole 12.

[0032] The support column 13 is inserted into the transverse fixing hole 12 and can slide laterally within the hole to adjust its extension length. The inner end of the support column 13 is fixedly connected to a transverse support plate 14. Threaded holes are spaced apart on both sides of the cleaning box 3, and positioning holes 15 are also opened at corresponding positions on the transverse support plate 14. When installing the cleaning box 3, the symmetrical transverse support plates 14 are moved closer to the center, and then the cleaning box 3 is connected to the transverse support plate 14 with bolts to complete the installation.

[0033] The L-shaped support column 11 has a positioning hole 15 at its top, and a locking bolt 16 is threaded into the positioning hole 15. In this embodiment, by loosening the locking bolt 16, the lateral position of the support column 13 can be adjusted. After adjusting to the appropriate position, it can be locked again, which facilitates the connection and disassembly of the lateral support plate 14 and the side wall of the cleaning box 3. It also facilitates fine-tuning during installation to adapt to different sizes of the cleaning box 3 or to adjust the precise position of the cleaning box 3 on the conveyor line.

[0034] The jet cleaning device 4 includes parallel, spaced vertical water pipes 41. Multiple high-pressure nozzles 42 are installed on the side of the vertical water pipes 41 facing the cleaning basket 2. The tops of the vertical water pipes 41 are interconnected via horizontal water pipes 43. A water connector 44 is installed on the top of the cleaning tank 3. The water connector 44 is connected to the horizontal water pipes 43 via a water hose. In this embodiment, the water connector 44 is connected to the output end of the high-pressure water pump via an external pipeline. High-pressure water flows through the water connector 44 and the water hose into the horizontal water pipes 43, and is then diverted to the vertical water pipes 41 on both sides. Finally, it is sprayed at high speed from each high-pressure nozzle 42, providing concentrated and effective rinsing of the multi-way valve orifices precisely located at the cleaning station. This pipeline layout ensures that the cleaning medium can evenly and powerfully cover the critical parts of the workpiece to be cleaned.

[0035] The inlet and outlet of the cleaning tank 3 are both equipped with detachable curtains 31. In this embodiment, in order to further optimize the user experience and working environment, detachable curtains 31 are installed on the top of the inlet and outlet of the cleaning tank 3.

[0036] The shielding curtain 31 is made of flexible, wear-resistant material, and its top is detachably connected to the upper edge of the opening of the cleaning tank 3. As a preferred option, a magnetic connection can be used, where magnetic strips are installed on the tank frame and attract the magnetic components at the edge of the shielding curtain 31, allowing for quick assembly and disassembly. Alternatively, it can be mechanically secured using bolt assemblies.

[0037] In operation, the shielding curtain 31 hangs down naturally to form a flexible barrier. This design allows the cleaning basket 2 to pass smoothly during transport, while effectively blocking splashes and water mist generated inside the cleaning tank 3 due to high-pressure jetting. This significantly reduces the leakage of cleaning fluid, keeps the workshop environment clean and the floor dry, and improves the collection efficiency of the waste liquid recovery system.

[0038] The cleaning basket 2 includes a metal rectangular frame 21. The outer side of the metal rectangular frame 21 is woven with wire to form a mesh structure. Two snap-fit ​​blocks 22 are symmetrically connected to the bottom of the cleaning basket 2. The snap-fit ​​blocks 22 are snapped into the limiting member. In this embodiment, the outer side of the frame is woven with wire to form a transparent mesh sidewall and bottom. This structure can ensure that the high-pressure cleaning fluid can penetrate fully and provide a stable space for the multi-way valve. When the cleaning basket 2 is placed, the snap-fit ​​blocks 22 are aligned with the corresponding snap-fit ​​members to snap into place, so that it can be transported while maintaining stability.

[0039] The limiting component includes at least two sets of L-shaped limiting blocks 6 arranged opposite each other, which together enclose a square limiting space. A support block 61 is provided in the middle of the square limiting space, and the support block 61 and the L-shaped limiting blocks 6 on both sides form a locking space corresponding to the locking block 22. The L-shaped limiting blocks 6 and the support block 61 are arranged at intervals on the conveyor chain plate. In this embodiment, during installation, the locking block 22 at the bottom of the cleaning basket 2 is aligned and placed into the locking space to achieve precise positioning and reliable fixation of the cleaning basket 2 on the conveyor chain plate. This mating structure can effectively prevent the cleaning basket 2 from shifting or shaking during conveying and cleaning, ensuring that the valve hole of the multi-way valve is always accurately aligned with the spray cleaning device 4, thereby ensuring the uniformity and thoroughness of the cleaning effect, and also making it more convenient to pick up and put down the cleaning basket 2.

[0040] Two sets of limiting rings 23 are symmetrically arranged on the inner side of the cleaning basket 2. A concave handle 24 is slidably connected to the limiting ring 23. The bottom of the concave handle 24 is bent inward to form a limiting part. In this embodiment, to facilitate the picking and placing of the cleaning basket 2, two sets of limiting rings 23 are symmetrically installed on the inner side of the cleaning basket 2. The two ends of one set of concave handles 24 are respectively slidably inserted into the two oppositely arranged limiting rings 23, so that the handles can slide up and down along the limiting rings 23.

[0041] The bottom of the concave handle 24 is bent inward to form a limiting part. When the cleaning basket 2 needs to be moved, the operator can lift the handle upward, and its limiting part contacts the lower end of the limiting ring 23, thereby reliably positioning the handle in the lifting position for easy application of force. When the cleaning basket 2 is being transported or cleaned, the handle can be lowered to a lower position to avoid interference with the internal structure of the cleaning tank 3 or the water jet. This provides convenient handling while ensuring the safety and reliability of the equipment during operation, and does not occupy extra space, making the structure compact and practical.

[0042] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
