Description

Technical Field

[0001] The utility model relates to the field of valve cleaning devices, in particular to a valve cleaning device for production valves. Background Art

[0002] In the process of producing valves, grinding, cleaning and painting are required. Since mechanical processing will produce a lot of impurities on the surface of the valve, if it is not cleaned or the cleaning quality is poor, the quality of subsequent paint film formation will be greatly reduced. The presence of voids in the paint film will reduce the anti-oxidation ability of the paint film, making it a defective product, so a cleaning device is needed to clean it.

[0003] For example, the Chinese utility model (publication number CN220239400U) discloses a valve cleaning device for valve production, including a cleaning box, a belt conveyor, a positioning plate, a water distribution pipe, a nozzle, a cleaning waste water recovery mechanism and other structures. This technical solution can clean three sides of the valve at the same time, greatly improving the work efficiency of valve production; the waste water used for flushing can be filtered and collected, which can save the use of water resources.

[0004] However, the above technical solution still has the following technical problems in actual use: the device needs to be moved during use so as to be placed in different locations or on different production lines, and the cleaning box and belt conveyor are placed on the ground as a whole. When it needs to be moved, the device needs to be lifted and moved manually, which results in high labor intensity, inconvenience in use, and poor practicality. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0022] like Figures 1 to 4 The valve cleaning device for producing valves comprises a bottom plate 2 and a lifting plate 4, the bottom plate 2 is connected to a cleaning box 13 and a belt conveyor 1, the belt conveyor 1 is connected to a positioning plate 14, the left and right sides of the cleaning box 13 are respectively provided with through openings, the left and right sides of the belt conveyor 1 respectively pass through the through openings, the structures and use principles of the belt conveyor 1 and the positioning plate 14 are all prior art, and the Chinese utility model (publication number CN220239400U) also records them, which will not be repeated here; a water spray pipe 16 is connected to the inside of the cleaning box 13, the water spray pipe 16 can be externally connected to a water source and a water pump, the water spray pipe 16 is connected to a nozzle 17, and the water spray pipe 16 is provided with a plurality of groups, and the plurality of groups of water spray pipes 16 are respectively located on the top inner wall of the cleaning box 13, the front inner wall and the rear inner wall, so that the nozzle 17 can clean the valve of the cleaning box 13 in different directions, thereby improving the cleaning quality;

[0023] The bottom plate 2 is connected with a support rod 3, and the support rod is provided with several groups. The bottom plate 2 is rotatably connected with a bidirectional threaded rod 6, and the bottom plate 2 is connected with a servo motor 9 and an auxiliary slide bar 22. The output shaft of the servo motor 9 is connected with the bidirectional threaded rod 6, and the auxiliary slide bar 22 is arranged in parallel with the bidirectional threaded rod 6. The two ends of the bidirectional threaded rod 6 are respectively threadedly connected with a moving block 5, and the two moving blocks 5 are arranged symmetrically about the center line of the bidirectional threaded rod 6. The bidirectional threaded rod 6 includes a forward thread segment and a reverse thread segment, that is, the two moving blocks 5 are threadedly connected with the forward thread segment and the reverse thread segment, respectively. The moving block 5 is slidably connected with the auxiliary slide bar 22, and moves against the bottom of the bottom plate 2. The moving block 5 is hinged with a bearing rod 8, and the free end of the bearing rod 8 is hinged with the lifting plate 4, and the lifting plate 4 is connected with a universal wheel 7, and the lifting plate 4 is slidably connected with the support rod 3. Two bearing rods 8 are connected to one moving block 5, and the two bearing rods 8 are arranged symmetrically about the center line of the moving block 5.

[0024] The servo motor 9 drives the two-way threaded rod 6 to rotate. Since the auxiliary sliding rod 22 plays a role of rotation limiting the moving block 5, as the two-way threaded rod 6 rotates, the two moving blocks 5 move inward or outward along the two-way threaded rod 6 at the same time, thereby driving the bearing rod 8 to move, thereby completing the lifting and lowering adjustment of the lifting plate 4 and the universal wheel 7. Since the lifting plate 4 is slidably connected to the support rod 3, the support rod 3 plays a role of limiting the lifting plate 4, so that the lifting plate 4 can only move up and down along the support rod 3, and thus the lifting plate 4 cannot be easily moved after the position adjustment is completed, thereby ensuring the stability of the belt conveyor 1 and the cleaning box 13 when moving through the universal wheel 7.

[0025] A water outlet 10 is provided at the bottom of the cleaning box 13, a water storage tank 12 is placed on the bottom plate 2, the water storage tank 12 is connected to a drain pipe 18, the drain pipe 18 is connected to a control switch, and a filter screen 11 is threadedly connected to the cleaning box 13, and the filter screen 11 is located at the lower side of the water outlet 10.

[0026] The cleaning box 13 is connected to the mounting cylinder 15, the mounting cylinder 15 is connected to the mounting rod 20, the mounting rod 20 is connected to the fan assembly 19, the mounting cylinder 15 is connected to the electric heating wire 21, and a ventilation hole is provided on the top of the cleaning box 13, so that the outside air can flow smoothly into the mounting cylinder 15, so that the fan assembly 19 can blow the air stably; when in use, the fan assembly 19 blows the air, and the fan assembly 19 can blow out hot air downwards through the electric heating wire, so as to dry the valve below the mounting cylinder 15.

[0027] The specific implementation process is as follows:

[0028] When in use, it is grounded by the support rod 3, so that the belt conveyor 1 and the cleaning box 13 can be used stably. The valve to be cleaned is placed on the belt conveyor 1, and the valve is sent into the cleaning box 13 by the belt conveyor 1 and moves from right to left. Clean water is sent to the water spray pipe 16 through an external water pump and a water source and then sprayed out from the nozzle 17. After the valve enters the cleaning box 13, it is cleaned with clean water sprayed from the nozzle 17. The used cleaning water flows to the bottom of the cleaning box 13, is filtered by the filter net 11, and is discharged from the water outlet 10 and falls into the water storage tank 12 for storage. The valve continues to move from right to left, and moves to the bottom of the installation cylinder 15 after cleaning. The fan assembly 19 blows out hot air to dry the valve. After the valve is dried, it continues to move to the left and is sent out of the cleaning box 13, and then the valve after cleaning can be collected.

[0029] After using it for a period of time, the drain pipe 18 can be turned on to control the switch to recycle the clean water collected in the water tank 12, and the filter screen 11 can be unscrewed to clean the collected impurities. When the device needs to be moved, the servo motor 9 can be directly controlled to drive the bidirectional threaded rod 6 to rotate to move the universal wheel 7 down to the ground, and then the cleaning device can be quickly moved, which is also convenient for moving the water tank 12 to a suitable location to start draining, thereby improving practicality.

[0030] The present technical solution is provided with a lifting plate 4 and a universal wheel 7, and the universal wheel 7 can be driven by a servo motor 9 to move up and down. When the cleaning device is used, the support rod 3 is grounded to improve the stability of the cleaning device when it is placed and used. When the device needs to be moved, the universal wheel 7 can be grounded to quickly move the cleaning device, ensuring that the cleaning device is placed stably while facilitating its movement, reducing the labor intensity, and having a simple overall structure and being easy to use. It also avoids the situation where the universal wheel 7 is easily damaged by being grounded for a long time, thereby improving the stability of use and reducing the failure rate of maintenance; a fan assembly 19 and an electric heating wire 21 are provided to blow out hot water. Wind can be used to dry the cleaned valve to prevent clean water from adhering to the valve for a long time, which is convenient for subsequent processing and packaging and prevents the valve from rusting; clean water can be recycled through the drain port and the water storage tank 12; impurities can be filtered through the filter plate with threaded filtration to improve the quality of clean water recovery; the filter screen 11 can be quickly removed by threaded connection to clean impurities and ensure the passability of the filter screen 11; several groups of water spray pipes 16 are provided to clean the valve in all directions to improve the cleaning quality; multiple bearing rods 8 are provided to improve the stability of the universal wheel 7 and the lifting plate 4.
