Technical Field
[0001] This utility model relates to the field of filter bag spraying, specifically a high-temperature filter bag surface spraying device. Background Technology
[0002] Filter bags are a crucial component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically within the dust collector. In existing dust collectors, dust adheres to the outer surface of the filter bags. When dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bags, while clean gas passes through the filter media and enters the interior of the filter bags.
[0003] In the existing filter bag processing process, the filter bag is usually fitted onto the outside of a fixed support column for support before being sprayed. However, this support method is not convenient for supporting filter bags of various sizes, and the filter bags will be uneven, which can easily lead to uneven spraying and reduce the efficiency of spraying.
[0004] Therefore, a high-temperature filter bag surface spraying device is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] like Figures 1 to 5As shown, a high-temperature filter bag surface spraying device includes a workbench 1; a fixed plate 12 is fixedly connected to the top of the workbench 1, a first motor 13 is fixedly connected to the side of the workbench 1, a mounting column 14 is rotatably connected to the side of the fixed plate 12, the output end of the first motor 13 is fixedly connected to the mounting column 14, a first groove is formed inside the mounting column 14, an electric push rod 15 is fixedly connected inside the first groove, a push plate 16 is fixedly connected to the output end of the electric push rod 15, the push plate 16 is slidably connected to the mounting column 14, a second motor 17 is fixedly connected to the side of the workbench 1, a sliding groove is formed on the side of the workbench 1, a screw 18 is fixedly connected to the output end of the second motor 17, the screw 18 is rotatably connected to the sliding groove, a movable seat 19 is threadedly connected to the surface of the screw 18, a support plate 110 is fixedly connected to the inner side of the movable seat 19, the support plate 110 is slidably connected to the workbench 1, and a spray head 111 is fixedly connected to the top of the support plate 110; during operation, the filter bag is placed on the surface of the mounting column 14. The electric actuator 15 drives the pusher plate 16 to move outward, which in turn pushes and supports the inner wall of the filter bag, thus lifting the filter bag. The first motor 13 drives the mounting column 14 to rotate, which in turn drives the electric actuator 15 and the pusher plate 16 to rotate, which in turn drives the filter bag to rotate. The second motor 17 drives the screw 18 to rotate, which in turn drives the movable seat 19 to move left and right, which in turn drives the support plate 110 to move, which in turn drives the support plate 110 to move. The spray head 111 moves and sprays the filter bag when it passes the surface of the filter bag. This step is achieved by moving the push plate 16 through the electric push rod 15, which can support and position filter bags of different diameters from the inside to prevent the filter bags from becoming uneven. The first motor 13 drives the mounting column 14 so that the filter bag can rotate during spraying. The rotation of the screw 18 can drive the spray head 111 to move back and forth on the surface of the filter bag, repeatedly spraying the filter bag and increasing the efficiency of spraying the filter bag.
[0024] like Figure 1 and Figure 2 As shown, a collection trough 21 is provided on the top of the workbench 1. The collection trough 21 is inclined and the bottom of the collection trough 21 is connected to a discharge pipe 22. During operation, when the paint falls, it can enter the interior of the collection trough 21. The inclined arrangement of the collection trough 21 causes the paint inside to flow towards the discharge pipe 22 and be discharged from the discharge pipe 22. This step can collect the falling paint through the collection trough 21 and discharge the paint through the discharge pipe 22, thus recovering the falling paint.
[0025] like Figure 4 and Figure 5As shown, a heating box 31 is fixedly connected to the inner side of the spray head 111. A fan 32 is connected to the top of the heating box 31. An exhaust port is opened at the bottom of the heating box 31, and a heating wire is installed inside the heating box 31. During operation, when the spray head 111 moves, it drives the heating box 31 to move. The fan 32 blows air into the heating box 31, which heats the air passing through it and blows it out through the exhaust port at the bottom of the heating box 31 to blow air onto the painted filter bag. This step uses the fan 32 to blow hot air onto the surface of the filter bag, increasing the drying speed of the filter bag after it is painted.
[0026] like Figure 1 and Figure 2 As shown, a storage groove 41 is provided on the surface of the mounting post 14, and a guide groove 42 is provided on the side of the storage groove 41. During operation, the electric push rod 15 can drive the push plate 16 into the interior of the storage groove 41. When the paint enters the interior of the storage groove 41, it can fall through the guide groove 42. This step allows the push plate 16 to be stored in the storage groove 41, making it easier for the filter bag to be put on the surface of the mounting post 14. The guide groove 42 facilitates the discharge of the paint inside the storage groove 41, making it easier for the paint on the surface of the mounting post 14 to fall off.
[0027] like Figures 1 to 3 As shown, a cleaning ring 51 is slidably connected to the surface of the mounting post 14, and a pull ring is fixedly connected to the surface of the cleaning ring 51. During operation, after the spraying work is completed, the push plate 16 enters the interior of the storage groove 41. The cleaning ring 51 can be moved by the pull ring to scrape and clean the surfaces of the mounting post 14 and the push plate 16. This step of pulling the pull ring can drive the cleaning ring 51 to scrape and clean the surface of the mounting post 14, reducing the amount of paint residue on the surface of the mounting post 14.
[0028] like Figures 1 to 5 As shown, a scraper 61 is fixedly connected to the side of the support plate 110, and the bottom surface of the scraper 61 is in contact with the workbench 1. During operation, when the support plate 110 moves, it drives the scraper 61 to move. In this step, the scraper 61 is set at an angle. When it moves, it can scrape the paint on the surface of the workbench 1 into the inside of the collection tank 21 to clean the surface of the workbench 1.
[0029] The working principle is as follows: A filter bag is fitted onto the surface of the mounting column 14. An electric actuator 15 drives a pusher plate 16 to move outwards, which in turn pushes and supports the inner wall of the filter bag, lifting it up. A first motor 13 drives the mounting column 14 to rotate, which in turn rotates the electric actuator 15 and the pusher plate 16, causing the filter bag to rotate. A second motor 17 drives a screw 18 to rotate, which in turn moves a movable seat 19 left and right. The movable seat 19 then moves a support plate 110, which in turn moves the spray head 111 and the scraper 61. When the spray head 111 passes over the surface of the filter bag... The filter bags are sprayed. When the spray head 111 moves, it drives the heating box 31 to move. The fan 32 blows air into the heating box 31, which heats the air passing through it and blows it out through the exhaust hole at the bottom of the heating box 31. The sprayed filter bags are then blown with air. After the spraying work is completed, the push plate 16 enters the inside of the collection tank 41. The cleaning ring 51 can be moved by the pull ring to scrape and clean the surfaces of the mounting column 14 and the push plate 16. When the sprayed paint falls, it can enter the inside of the collection tank 21. The inclined setting of the collection tank 21 causes the sprayed paint inside to flow to the discharge pipe 22 and be discharged from the discharge pipe 22.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
