Description

Technical Field

[0001] This utility model relates to the field of hydraulic valve technology, and in particular to a hydraulic valve cleaning device. Background Technology

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressurized oil of a distribution valve and is usually used in combination with a solenoid distribution valve. It can be used for remote control of the on / off of oil, gas, and water pipeline systems in hydropower stations. It is commonly used in hydraulic circuits for clamping, control, and lubrication. During routine maintenance of hydraulic valves, cleaning equipment is required to clean them.

[0003] However, while existing cleaning equipment can perform good cleaning operations on hydraulic valves, it often places the valves to be cleaned directly into the cleaning area of ​​the cleaning nozzle. The pre-soaking effect of the valves before cleaning is not high, resulting in hardened impurities on the valve surface. This makes cleaning the hardened impurities by the cleaning nozzle cumbersome, reducing the cleaning efficiency of the cleaning equipment on the valves. At the same time, it also reduces the cleanliness of the cleaning equipment in removing impurities from the valve surface.

[0004] Therefore, those skilled in the art have provided a hydraulic valve cleaning device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue that traditional methods of directly placing valves to be cleaned in the cleaning area of ​​a cleaning nozzle are ineffective due to the lack of proper pre-soaking before cleaning, this invention provides a hydraulic valve cleaning device.

[0006] This utility model provides a hydraulic valve cleaning device, which adopts the following technical solution:

[0007] A hydraulic valve cleaning device includes a cleaning tank with a vibrating screen plate inside. A filter box is fixedly connected to the bottom of the cleaning tank, and a connecting pipe is fixedly connected to the outer wall of the filter box. An adjusting cylinder is fixedly connected to one end of the connecting pipe, and a cleaning pipe is fixedly connected to the outer wall of the adjusting cylinder. A cleaning nozzle located above the vibrating screen plate is fixedly connected to one end of the cleaning pipe via a cleaning pump. A conversion pipe is fixedly connected to the outer wall of the adjusting cylinder, and a pre-wash box is fixedly connected to one end of the conversion pipe via the connecting pump. A servo motor is installed at the top of the adjusting cylinder, and a worm gear is fixedly connected to the output end of the servo motor. A worm wheel meshes with the outer wall of the worm gear, and the rotation center of the worm wheel is fixedly connected to a conversion cylinder rotatably connected to the inner wall of the adjusting cylinder via a rotating shaft.

[0008] Optionally, a flip plate is rotatably connected to the inner wall of the pre-wash box, and an electric push rod is provided on the outer wall of the pre-wash box. One end of the electric push rod is fixedly connected to a push plate that is slidably connected to the inner wall of the pre-wash box.

[0009] Optionally, the cleaning nozzle is slidably connected to the top of the cleaning tank, and the cross-section of the connection between the connecting pipe and the cleaning pipe and the conversion pipe is T-shaped.

[0010] Optionally, the inner wall of the adjusting cylinder is provided with an adjusting cavity that matches the outer wall of the conversion cylinder, and the inner wall of the conversion cylinder is provided with a storage cavity.

[0011] Optionally, the conversion cylinder forms a rotating structure with the adjusting cylinder through a worm and a worm wheel.

[0012] Optionally, the pre-wash box is positioned on the movement trajectory of the vibrating screen plate, and the width of the vibrating screen plate is greater than the width of the pre-wash box.

[0013] Optionally, a discharge port is provided at the connection between the outer wall of the pre-wash box and the flip plate, and the pre-wash box is used to place the hydraulic valves to be cleaned.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a pre-wash box, improves the cleaning efficiency of hydraulic valves during cleaning by pre-soaking them, thus softening impurities on the valve surface. This allows the impurities to be quickly removed during subsequent nozzle cleaning. When the cleaning water is recycled through the filter box, the worm gear drives the worm wheel to rotate. The rotation of the worm wheel causes the conversion cylinder to rotate along the inner wall of the regulating cylinder, allowing the filtered cleaning water to be transported to the pre-wash box through the conversion pipe, where the valves are fully soaked.

[0016] 2. By setting up a push plate, this utility model allows the flip plate to be opened and the push plate to be driven when the soaked valve parts need to be unloaded for cleaning, so that the soaked valve parts fall onto the vibrating screen plate, thereby further improving the cleaning efficiency of hydraulic valve parts.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] Example 1:

[0025] Please refer to Figure 1-4 A hydraulic valve cleaning device includes a cleaning tank 1, a vibrating screen plate 2 inside the cleaning tank 1, a filter box 3 fixedly connected to the bottom of the cleaning tank 1, a connecting pipe 4 fixedly connected to the outer wall of the filter box 3, an adjusting cylinder 5 fixedly connected to one end of the connecting pipe 4, a cleaning pipe 6 fixedly connected to the outer wall of the adjusting cylinder 5, a cleaning nozzle 7 located above the vibrating screen plate 2 fixedly connected to one end of the cleaning pipe 6 via a cleaning pump, a conversion pipe 8 fixedly connected to the outer wall of the adjusting cylinder 5, a pre-wash box 9 fixedly connected to one end of the conversion pipe 8 via a connecting pump, a servo motor 10 installed at the top of the adjusting cylinder 5, a worm gear 11 fixedly connected to the output end of the servo motor 10, a worm wheel 12 meshing with the outer wall of the worm gear 11, and a conversion cylinder 13 rotatably connected to the inner wall of the adjusting cylinder 5 via a rotating shaft at the rotation center of the worm wheel 12.

[0026] In this embodiment: When cleaning hydraulic valves using cleaning equipment, in order to further improve the cleaning efficiency, a pre-soaking operation is performed on the valves to be cleaned, so that the impurities on the surface of the valves are fully softened. During the subsequent nozzle cleaning, the impurities on the surface of the valves can be quickly removed. When the cleaning water is recycled and reused through the filter box 3, the worm gear 11 drives the worm wheel 12 to rotate. The rotation of the worm wheel 12 drives the conversion cylinder 13 to rotate along the inner wall of the regulating cylinder 5, so that the filtered cleaning water is transported to the pre-wash box 9 through the conversion pipe 8 to fully soak the valves in the pre-wash box 9.

[0027] In this embodiment: a flip plate 14 is rotatably connected to the inner wall of the pre-wash box 9, and an electric push rod 15 is provided on the outer wall of the pre-wash box 9. One end of the electric push rod 15 is fixedly connected to a push plate 16 that is slidably connected to the inner wall of the pre-wash box 9. When it is necessary to unload and clean the soaked valve parts, the flip plate 14 is opened and the push plate 16 is driven so that the soaked valve parts fall onto the vibrating screen plate 2, thereby further improving the cleaning efficiency of the hydraulic valve parts.

[0028] In this embodiment, the cleaning nozzle 7 is slidably connected to the top of the cleaning tank 1, and the cross-section of the connection between the connecting pipe 4 and the cleaning pipe 6 and the conversion pipe 8 is T-shaped. By setting the cleaning nozzle 7 to be slidably connected to the top of the cleaning tank 1, the valves on the vibrating screen plate 2 can be cleaned in all directions.

[0029] In this embodiment: the inner wall of the regulating cylinder 5 is provided with an regulating cavity that is adapted to the outer wall of the conversion cylinder 13, and the inner wall of the conversion cylinder 13 is provided with a storage cavity, which is beneficial to the conversion of the transport path of the filtered and recycled water resources through the storage cavity in the inner wall of the conversion cylinder 13.

[0030] In this embodiment, the conversion cylinder 13 forms a rotating structure with the regulating cylinder 5 through the worm 11 and the worm wheel 12, which is beneficial for the worm 11 to drive. Through the connection of the worm wheel 12, the conversion cylinder 13 is driven to rotate along the inner wall of the regulating cylinder 5, thereby playing the role of transporting water resources to the pre-wash box 9.

[0031] In this embodiment, the pre-wash box 9 is set on the movement trajectory of the vibrating screen plate 2. The width of the vibrating screen plate 2 is greater than the width of the pre-wash box 9, which is beneficial for the pre-wash box 9 to be set on the movement trajectory of the vibrating screen plate 2, so as to accurately replenish the valve parts after soaking.

[0032] In this embodiment, a discharge port is provided at the connection between the outer wall of the pre-wash box 9 and the flip plate 14. The pre-wash box 9 is used to place the hydraulic valve components to be cleaned. The discharge port at the connection between the outer wall of the pre-wash box 9 and the flip plate 14 further improves the cleaning efficiency of the hydraulic valve components.

[0033] The implementation principle of this utility model is as follows: In use, firstly, when cleaning the hydraulic valve components using the cleaning equipment, in order to further improve the cleaning efficiency of the valve components, a pre-soaking operation is performed on the valve components to be cleaned, so that the impurities on the surface of the valve components are fully softened. During the subsequent nozzle cleaning, the impurities on the surface of the valve components can be quickly removed. When the cleaning water is recycled and reused through the filter box 3, the worm gear 11 can drive the worm wheel 12 to rotate. The rotation of the worm wheel 12 drives the conversion cylinder 13 to rotate along the inner wall of the regulating cylinder 5, so that the filtered cleaning water is transported to the pre-wash box 9 through the conversion pipe 8, and the valve components in the pre-wash box 9 are fully soaked.

[0034] Finally, when it is necessary to unload and clean the soaked valve parts, open the tilting plate 14 and drive the push plate 16 so that the soaked valve parts fall onto the vibrating screen plate 2, thereby further improving the cleaning efficiency of the hydraulic valve parts.

[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
