Description

Technical Field

[0001] This utility model relates to the field of spray machine technology, specifically a spray machine that can clean the inner wall. Background Technology

[0002] During the production process, strip steel undergoes various processes, including different pressure rolling mills, sulfuric acid cleaning, and annealing, to complete the finished product. Strip steel can be used to produce various required thin sheet products. When the strip steel is pressed by a rolling mill, an emulsion is used to lubricate the surface and assist in the production process. This emulsion often contains a significant amount of oil or other chemicals, resulting in a considerable amount of oil and dirt on the strip steel surface. When the strip steel is processed into finished products, a spray cleaning machine is used to spray and clean its surface to ensure the surface quality of the steel sheet.

[0003] Currently, in the process of cleaning strip steel by spraying through spray pipes and nozzles, dirt gradually accumulates on the inner wall of the spray pipes, which affects the spraying effect. Moreover, the cleaning effect will decrease significantly with the increase of usage time. In addition, the impurities accumulated on the inner wall of the spray pipes can easily cause nozzle blockage, and the dirt can also easily corrode the spray pipes, shortening their service life. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sprayer that can clean the inner wall, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray machine capable of cleaning the inner wall, comprising a cleaning tank, a chain conveyor, and a spraying mechanism. The chain conveyor is arranged inside the cleaning tank, and the spraying mechanism is arranged above the chain conveyor on the inner side of the cleaning tank. The spraying mechanism includes a water inlet pipe, a spray pipe, and a nozzle. The water inlet pipe is installed at the front end of the cleaning tank via a side plate, and the spray pipe, which is connected to the water inlet pipe via a sealed bearing, is connected to the inner side of the cleaning tank.

[0006] The rear end of the cleaning tank is provided with a cleaning mechanism extending into the interior of the spray pipe.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A sprayer that can clean the interior walls, such as Figures 1-4 As shown, the system includes a cleaning tank 1, a chain conveyor 2, and a spraying mechanism 3. The chain conveyor 2 is installed inside the cleaning tank 1, and the spraying mechanism 3 is installed above the chain conveyor 2 inside the cleaning tank 1. The spraying mechanism 3 includes an inlet pipe 301, a spray pipe 302, and spray nozzles 303. The inlet pipe 301 is installed at the front end of the cleaning tank 1 through a side plate. The spray pipe 302 is connected to the inlet pipe 301 through a sealed bearing on the inside of the cleaning tank 1. Spray nozzles 303 are installed at the bottom end of the spray pipe 302 and are equidistantly arranged at the bottom end of the spray pipe 302.

[0027] See Figures 1-4 It can be seen that the strip steel is conveyed by the chain conveyor 2, and at the same time, the water inlet pipe 301 sends water into the spray pipe 302 and sprays the strip steel to clean it through the nozzle 303.

[0028] See Figure 1 and Figure 4It is known that the top of the cleaning pool 1 is provided with a limiting groove 6, and the bottom of the toothed plate 503 is provided with a limiting block 7. The toothed plate 503 and the cleaning pool 1 form a sliding structure through the limiting groove 6 and the limiting block 7, which can play a role in supporting and limiting the toothed plate 503, thereby increasing the stability of the toothed plate 503 during the sliding process.

[0029] See Figures 1-3 It is known that a cleaning mechanism 4 extending into the spray pipe 302 is provided at the rear end of the cleaning tank 1. The cleaning mechanism 4 includes a cleaning brush plate 401, a connecting plate 402, a movable frame 403, a first electric push rod 404, a support rod 405, a movable trough 406, and a mounting frame 407. The mounting frame 407 is located at the rear end of the chain conveyor 2, and the front end of the mounting frame 407 is provided with a support rod 405 connected to the spray pipe 302 via a sealed bearing. The cleaning brush plate 401 is movably connected to the outer side of the support rod 405, and the inner side of the support rod 405... The part has an open movable slot 406, and a movable frame 403 is slidably connected inside the movable slot 406. An electric push rod 404 is installed between the movable frame 403 and the movable slot 406. The movable frame 403 is composed of a disc and a cylinder. The cleaning brush plate 401 is rotatably connected to the movable frame 403 through a hinge seat and a connecting plate 402. Three connecting plates 402 are arranged at equal angles around the movable frame 403. The cleaning brush plate 401 is set with an arc-shaped structure, and three cleaning brush plates 401 are arranged at equal angles around the movable frame 403.

[0030] See Figure 3 As can be seen, since the cleaning brush plate 401 and the movable frame 403 are linked through the connecting plate 402, when the first electric push rod 404 works and retracts, the movable frame 403 moves horizontally. At the same time, the connecting plate 402 pushes the cleaning brush plate 401 to unfold and fit against the inner wall of the spray pipe 302. This allows the cleaning brush plate 401 to clean the inner wall of the spray pipe 302 in all directions during the rotation of the spray pipe 302, effectively extending the service life of the spray pipe 302 and improving the spray cleaning efficiency and effect of the sprayer.

[0031] See Figures 1-4 It is known that the top of the cleaning pool 1 is provided with a swing mechanism 5 connected to the spray pipe 302. The swing mechanism 5 is composed of a mounting block 501, a second electric push rod 502, a toothed plate 503 and a gear 504. A gear 504 is sleeved on one end of the outer side of the spray pipe 302. The top of the gear 504 is meshed with the toothed plate 503. The top of the cleaning pool 1 is provided with a mounting block 501. A second electric push rod 502 is installed between the mounting block 501 and the toothed plate 503.

[0032] See Figures 1-4It can be seen that since the spray pipe 302 is rotatably connected to the cleaning tank 1 through the bearing, and the gear 504 is meshed with the toothed plate 503, the toothed plate 503 slides horizontally during the operation and extension of the second electric push rod 502. At the same time, the gear 504 and the spray pipe 302 reciprocate in both forward and reverse directions, so that the spray head 303 can swing and spray the strip steel for cleaning, thereby expanding the spray cleaning range and improving the spray cleaning efficiency of the spray machine.

[0033] The working principle of this utility model is as follows: When using the sprayer that can clean the inner wall, the strip steel is conveyed by the chain conveyor 2, and water is simultaneously supplied to the spray pipe 302 through the water inlet pipe 301 and sprayed onto the strip steel through the nozzle 303. During this process, the second electric push rod 502 works and extends and retracts, causing the toothed plate 503 to slide horizontally, and at the same time causing the gear 504 and the spray pipe 302 to reciprocate in both forward and reverse directions, thereby allowing the nozzle 303 to swing and spray onto the strip steel for cleaning. When the spray pipe 302 needs to be cleaned, the sprayer can clean the strip steel by spraying. At time 2, the first electric push rod 404 is activated and retracted, causing the movable frame 403 to move horizontally. At the same time, the cleaning brush plate 401 is pushed towards the inner wall of the spray pipe 302 through the connecting plate 402 and unfolds and fits against it. This allows the cleaning brush plate 401 to clean the inner wall of the spray pipe 302 in all directions during the rotation of the spray pipe 302, effectively extending the service life of the spray pipe 302.
