Description

Technical Field

[0001] This utility model relates to the field of soot blowers, and more particularly to an adjustable boiler soot blower. Background Technology

[0002] A gooseneck valve soot blower is a device used to remove ash from industrial boilers, heat exchangers, or flue gas ducts. Its core feature is a valve system with a gooseneck-shaped pipe structure, which removes dust and slag from the surface of the equipment through pulsed injection of high-pressure gas.

[0003] When the gooseneck valve sootblower is in operation, the nozzle can move back and forth and rotate with the help of the transmission structure set on the outside of the gooseneck valve. This allows the nozzle to first extend into the device and then rotate to blow soot, resulting in a good cleaning effect. However, the movement and rotation of the nozzle mainly rely on the threads and cams set on the outer wall of the nozzle. Since the cam and threads themselves cannot be adjusted, the extension length of the nozzle of the gooseneck valve sootblower is a fixed value when in operation. Therefore, when it is necessary to adjust the soot blowing depth, the installation position of the entire device needs to be adjusted, which is inconvenient. To solve the above problems, an adjustable boiler sootblower is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable boiler soot blower, which aims to improve the problem in the prior art that "when it is necessary to adjust the installation position of the entire device, the soot blowing depth needs to be adjusted".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable boiler soot blower, comprising: A gooseneck valve is used to support the overall device. An air guide tube is installed on the outer wall of the gooseneck valve, and an air blowing tube is piston-connected to the outer wall of the air guide tube. A geared motor, mounted on the left side of the gooseneck valve, is used to provide power for the movement of the air blowing tube; The transmission assembly, located above the gooseneck valve, is used to drive the air blowing pipe to move; A transmission cam is sleeved on the outer wall of the air blowing pipe. A support plate is provided on the left side of the transmission cam. The support plate is fixedly connected to the outer wall of the air blowing pipe. A connecting block is inserted into the inner wall of the support plate. The connecting block is installed on the left surface of the transmission cam. A hinge plate is hinged to the lower surface of the connecting block. A slider is hinged to the lower surface of the hinge plate. The slider slides on the inner wall of the support plate.

[0006] As a further description of the above technical solution: A support block is fixedly connected to the inner wall of the support plate, and an adjusting screw is rotatably connected to the lower surface of the support block. The slider is threadedly connected to the outer wall of the adjusting screw.

[0007] As a further description of the above technical solution: A guide rod is fixedly connected to the left surface of the connecting block, and the guide rod passes through and is slidably connected to the left end of the support plate.

[0008] As a further description of the above technical solution: The guide rod is configured as a hollow cylindrical sleeve, and the transmission cam has a threaded hole at one end near the guide rod.

[0009] As a further description of the above technical solution: A drive shaft is installed at the right end of the output shaft of the geared motor, and the transmission assembly includes a drive wheel, which is fixedly connected to the outer wall of the drive shaft.

[0010] As a further description of the above technical solution: The upper surface of the gooseneck valve is rotatably connected to a driven wheel, and the driven wheel and the driving wheel mesh with each other. The outer wall of the air blowing pipe is provided with a threaded groove, and the air blowing pipe meshes with the driven wheel.

[0011] As a further description of the above technical solution: A cam sleeve is fixedly connected to the left surface of the passive wheel, and the cam sleeve is adapted to the transmission cam.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by setting a movable cam, when it is necessary to reduce the extension length, the cam can be moved to the right. In this way, when the air pipe moves, the cam will contact the cam sleeve in advance, so that the air pipe can not continue to move to the right, thereby achieving the effect of reducing the extension length. Moreover, it does not require adjustment of the installation position of the overall device, which is more convenient during adjustment.

[0013] 2. In this utility model, the connecting block is guided by a guide rod, which can ensure that the connecting block is relatively stable when moving horizontally. At the same time, the connecting block is supported by the sliding block pushing the hinge plate. When the cam comes into contact with the cam sleeve, the cam will press the connecting block to the left, and the connecting block can press the hinge plate. The hinge plate itself is inclined, which can disperse some of the impact, thus improving the service life of the device. Attached Figure Description

[0016] 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.

[0017] Reference Figures 1-3This utility model provides an embodiment of an adjustable boiler soot blower, comprising: a gooseneck valve 1 for supporting the overall device; the gooseneck valve 1 is hollow inside, and its bottom end can be directly connected to the gas supply pipe through a flange to achieve gas supply operation; a gas guide pipe 7 is installed on the outer wall of the gooseneck valve 1, and a blowing pipe 4 is piston-connected to the outer wall of the gas guide pipe 7; when high-pressure gas enters the interior of the gooseneck valve 1, it will enter the interior of the gas guide pipe 7 along the inner wall of the gooseneck valve 1, and then pass through the gas guide pipe 7 into the interior of the blowing pipe 4; a geared motor 2, installed on the left side of the gooseneck valve 1, for providing power for the movement of the blowing pipe 4; the geared motor 2 consists of a servo motor and a reducer, and the output shaft of the reducer can be driven by starting the servo motor; a transmission assembly 5, located above the gooseneck valve 1, for driving the movement of the blowing pipe 4; and a transmission cam 6, sleeved on the outer wall of the blowing pipe 4. In the prior art, the transmission cam 6 is generally directly fixed to the outer wall of the blowing pipe 4, so when the blowing pipe 4 moves left and right, the transmission cam... 6 will also move synchronously with it. Similarly, when the transmission cam 6 is blocked and cannot continue to rotate, the air pipe 4 will also be restricted from moving to the right. In this application, the transmission cam 6 can move on the outer wall of the air pipe 4. Therefore, the timing of stopping the movement of the air pipe 4 can be controlled by adjusting the relative position of the transmission cam 6 and the air pipe 4. A support plate 61 is provided on the left side of the transmission cam 6. The support plate 61 is fixedly connected to the outer wall of the air pipe 4. When the support plate 61 moves, the support plate 61 will be driven synchronously. The inner wall of the support plate 61 is fitted with a connecting block 62, which is mounted on the left surface of the transmission cam 6. The connecting block 62 can be detached from the inner wall of the support plate 61. The lower surface of the connecting block 62 is hinged with a hinge plate 64 for supporting the connecting block 62. The lower surface of the hinge plate 64 is hinged with a slider 66, which slides on the inner wall of the support plate 61. When the slider 66 moves upward, the connecting block 62 is forced to move to the right, thus pushing the transmission cam 6 to move to the right on the outer wall of the air pipe 4.

[0018] Reference Figures 3-5 A support block 67 is fixedly connected to the inner wall of the support plate 61 to support the rotation of the adjusting screw 65. The adjusting screw 65 is rotatably connected to the lower surface of the support block 67. The slider 66 is threadedly connected to the outer wall of the adjusting screw 65. Rotating the adjusting screw 65 will drive the slider 66 to move up and down. A guide rod 63 is fixedly connected to the left surface of the connecting block 62 to guide the movement of the connecting block 62. The guide rod 63 passes through and is slidably connected to the left end of the support plate 61. By setting the guide rod 63, the connecting block 62 can be guided to move stably left and right. The guide rod 63 is set as a hollow cylindrical sleeve. A threaded hole 68 is set at one end of the transmission cam 6 near the guide rod 63. The guide rod 63 and the transmission cam 6 can be fixed by using a long bolt to pass through the guide rod 63 and the threaded hole 68.

[0019] Reference Figures 3-5The right end of the output shaft of the geared motor 2 is equipped with a transmission shaft 3 for transmitting power. The transmission assembly 5 includes a driving wheel 51 for rotating the driven wheel 52. The driving wheel 51 is fixedly connected to the outer wall of the transmission shaft 3. The driven wheel 52 is rotatably connected to the upper surface of the gooseneck valve 1. The driving wheel 51 and the driven wheel 52 mesh with each other. By starting the geared motor 2, the driving wheel 51 can be rotated, thus driving the driven wheel 52 to rotate. The outer wall of the air blowing pipe 4 is provided with a threaded groove, and the air blowing pipe 4 meshes with the driven wheel 52. When the driven wheel 52 rotates, it will drive the air blowing pipe 4 to move to the right by squeezing the threaded groove, thus driving the air blowing pipe 4 to be inserted into the furnace. The left surface of the driven wheel 52 is fixedly connected to a cam sleeve 53 for accommodating the transmission cam 6. The cam sleeve 53 is adapted to the transmission cam 6. When the air blowing pipe 4 moves to the right, it will drive the transmission cam 6 to move to the right and be inserted into the cam sleeve 53. At this time, the air blowing pipe 4 will be blocked and cannot move to the right. Thus, the rotation of the driven wheel 52 will drive the air blowing pipe 4 to rotate, thereby realizing the rotational air blowing cleaning.

[0020] Working principle: After the geared motor 2 starts, it drives the driving wheel 51 to rotate through the transmission shaft 3. The driving wheel 51 meshes with the driven wheel 52 to make it rotate. The driven wheel 52 drives the air blowing pipe 4 to move to the right through the threaded groove on the outer wall of the air blowing pipe 4 and insert it into the furnace. At the same time, the air blowing pipe 4 drives the support plate 61 fixed on its outer wall to move. The transmission cam 6 is connected to the slider 66 through the connecting block 62 and the hinge plate 64. Rotating the adjusting screw 65 can drive the slider 66 to slide up and down on the inner wall of the support plate 61. Through the hinge plate 64, the connecting block 62 is pushed, so that the transmission cam 6 moves left and right along the outer wall of the air blowing pipe 4, adjusting its relationship with the driven wheel. The relative position of the cam sleeve 53 on the left surface of 52 is such that when the air pipe 4 moves to the right, if the transmission cam 6 enters the cam sleeve 53, it will be blocked, thus stopping the movement of the air pipe 4. At this time, the driven wheel 52 continues to rotate, which drives the air pipe 4 to rotate, thereby achieving purging. By adjusting the position of the transmission cam 6, the timing of its contact with the cam sleeve 53 can be changed, thereby controlling the extension length of the air pipe 4. The guide rod 63 passes through the left end of the support plate 61 and is slidably connected to ensure that the connecting block 62 moves stably. If necessary, the guide rod 63 can be fixed in position by passing through the threaded hole 68 of the transmission cam 6 with a long bolt to accurately adjust the soot blowing depth.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
