Description

Technical Field

[0001] This utility model relates to the field of desulfurization pipeline cleaning technology, specifically a flue gas desulfurization device that can self-clean up scale buildup. Background Technology

[0002] Desulfurization pipelines are a type of transport pipeline used in desulfurization systems. Because these systems transport solutions containing acidic or alkaline substances, the pipelines must be corrosion-resistant, wear-resistant, and temperature-resistant to ensure the normal operation of the desulfurization system. Commonly used desulfurization pipelines include stainless steel, high-alloy composite steel plates, glass flake steel, and coated linings. However, rubber-lined pipelines are the most widely used in the market. During the transport of desulfurized flue gas, dust entrained in the flue gas easily adheres to the inner wall of the desulfurization pipeline, requiring regular cleaning.

[0003] When cleaning pipelines, water backflushing or a drain cleaning rod is usually used. However, for some curved pipelines, the drain cleaning rod cannot clean them thoroughly, and water backflushing is not suitable for cleaning in some special environments. If dirt accumulates for a long time, it can easily affect the transportation of desulfurized flue gas and thus affect the operation of the overall equipment. Therefore, we have proposed a self-cleaning flue gas desulfurization device to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By adjusting the mechanism, this utility model allows the connecting parts and support rods to be adjusted to the appropriate positions when cleaning desulfurization pipelines is required. This enables the cleaning brush to fit into the inner cavity of the pipeline. With the cooperation of the first motor, transmission rod, and movable ring, the device is suitable for pipelines of different sizes, thus improving its applicability.

[0015] 2.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a self-cleaning flue gas desulfurization device, comprising a fixed pipe 1, an adjusting mechanism 2 disposed inside the fixed pipe 1, a crushing head 3 fixedly installed at the left end of the fixed pipe 1, and the adjusting mechanism 2 comprising a first motor 201, a transmission rod 202, a movable ring 203, a connecting piece 204, and a support rod 205.

[0025] A first motor 201 is fixedly installed inside the fixed tube 1. A transmission rod 202 is provided at the left end of the first motor 201. A movable ring 203 is provided on the outside of the transmission rod 202. A connector 204 is provided on the left side of the movable ring 203. Six sets of support rods 205 are provided on the outside of the connector 204. A cleaning brush 6 is provided at the end of the support rod 205.

[0026] This device, through the setting of adjustment mechanism 2 and cleaning component 5, solves the problem that it is impossible to thoroughly clean the pipeline, and that water backflushing is not suitable for cleaning in some special environments. If dirt accumulates for a long time, it can easily affect the transportation of desulfurization flue gas, thereby affecting the operation of the overall equipment.

[0027] Furthermore, a guide assembly 4 is provided on the outer surface of the fixed tube 1. The guide assembly 4 includes a fixing block 41, a connecting rod 42, and a connecting hole 43. Two sets of fixing blocks 41 are provided on the outer side of the fixed tube 1 corresponding to the support rod 205. The connecting rod 42 is rotatably connected to the inner side of each of the two sets of fixing blocks 41. Connecting holes 43 are opened on the front and rear surfaces of the support rod 205. The other end of the connecting rod 42 is rotatably connected to the support rod 205 through the connecting hole 43. Figure 4 As shown, this structure is used to guide the support rod 205 in a specified direction when it moves via the support rod 205, under the connection of the connecting rod 42.

[0028] Furthermore, the right end of the transmission rod 202 is fixedly connected to the output end of the first motor 201, the left end of the transmission rod 202 is rotatably connected to the inner left wall of the fixed tube 1, the inner side of the movable ring 203 is provided with a thread adapted to the surface of the transmission rod 202, the right side of the connecting piece 204 is rotatably connected to the movable ring 203 through a bearing, and the inner end of the support rod 205 is rotatably connected to the connecting piece 204. Figure 2As shown, this structure is used to start the first motor 201, which drives the transmission rod 202 to rotate, causing the movable ring 203 on the surface of the transmission rod 202 to move to the left along the transmission rod 202. The connecting member 204 is rotatably connected to the movable ring 203, which in turn drives the connecting member 204 to move. When the connecting member 204 moves, the support rod 205 rotates outward, causing the cleaning brush 6 at the top of the support rod 205 to contact the inner wall of the pipe and clean the inner wall of the pipe.

[0029] Furthermore, a cleaning component 5 is provided at the end of the support rod 205. The cleaning component 5 includes a movable groove 51, a movable rod 52, a connecting plate 53, and a spring 54. A movable groove 51 is provided at the end of the support rod 205, and a movable rod 52 is movably connected within the movable groove 51. A connecting plate 53 is fixedly connected to the end of the movable rod 52. A spring 54 is provided inside the movable groove 51, and both ends of the spring 54 abut against the inner walls of the movable rod 52 and the movable groove 51, respectively. Figure 5 As shown, this structure is used to make the cleaning brush 6 move downward along the movable groove 51 when it comes into contact with the inner wall of the pipe, especially when encountering curved or multi-shaped pipes. This causes the movable rod 52 to squeeze the spring 54, making the cleaning brush 6 suitable for different types of pipes and improving the applicability of the device.

[0030] Furthermore, a drive assembly 7 is provided at the right end of the fixed tube 1. The drive assembly 7 includes a protective cover 71 and a second motor 72. The protective cover 71 is rotatably connected to the right end of the fixed tube 1, and the second motor 72 is fixedly installed inside the protective cover 71. The output end of the second motor 72 is fixedly connected to the fixed tube 1. Figure 3 As shown, this structure is used to start the second motor 72, which drives the fixed pipe 1 to rotate, so that the cleaning brush 6 cleans the inner wall of the pipe.

[0031] Furthermore, the outer surface of the connector 204 has six sets of sliders 8 arranged in a ring array, and the inner wall of the fixing tube 1 has six sets of sliding grooves 9 equidistantly spaced, the diameter of which is adapted to the sliders 8. Figure 3 As shown, this structure is used to move the connecting member 204 by the movable ring 203 through the slider 8 on the outside of the connecting member 204, and the connecting member 204 moves along the slide groove 9 through the slider 8.

[0032] Furthermore, slots 10 are equidistantly provided on the left side of the fixed tube 1, and the diameter of the slots 10 is adapted to the diameter of the two sets of connecting rods 42 and the support rod 205. For example... Figure 3 As shown, this structure is used to allow the connecting rod 42 to rotate as the support rod 205 moves through the slot 10, and to lock the end of the support rod 205 into the slot 10.

[0033] Working principle: When using, such as Figure 2 and Figure 3 As shown, first adjust the device according to the diameter of the pipe, start the first motor 201, which drives the transmission rod 202 to rotate, causing the movable ring 203 on the surface of the transmission rod 202 to move to the left along the transmission rod 202. The connecting piece 204 is rotatably connected to the movable ring 203, causing the connecting piece 204 to move. As the connecting piece 204 moves, the outer slider 8 moves along the slide groove 9. Simultaneously, as... Figure 2 and Figure 3 As shown, under the connecting action of the connecting rod 42, the support rod 205 is guided, causing the support rod 205 to rotate in the specified direction, bringing the cleaning brush 6 at the top of the support rod 205 into contact with the inner wall of the pipe, such as... Figure 1 and Figure 3 As shown, the second motor 72 is started, which drives the fixed pipe 1 to rotate, causing the cleaning brush 6 to clean the inner wall of the pipe. Figure 5 As shown, when encountering curved or multi-shaped pipes, the cleaning brush 6 moves the connecting plate 53 downward along the movable groove 51 when it comes into contact with the inner wall of the pipe, causing the movable rod 52 to squeeze the spring 54. When it moves to the appropriate inner wall, the cleaning brush 6 is brought into contact with the inner wall of the pipe again under the action of the spring 54. This allows the cleaning brush 6 to be used for different types of pipes. The above is the complete working principle of this utility model.
