Description

Technical Field

[0001] This utility model relates to the field of soot blowers, and more particularly to a telescopic furnace soot blower. Background Technology

[0002] The gooseneck valve sootblower is a common type of sootblower, mainly composed of an air supply pipe, nozzle, gooseneck valve, and drive assembly. It can extend into the furnace to complete the sootblowing operation. The outer wall of its air supply pipe is provided with an arc-shaped groove. By adjusting the drive assembly, the air supply head can be automatically driven to complete horizontal and rotary movements, making it convenient to use.

[0003] In the existing technology, the commonly used gooseneck valve sootblower mainly relies on the active movement of the air supply pipe to drive the nozzle to extend into the pipe to be cleaned. However, since the shape of the threaded groove on the outer wall of the air supply pipe is fixed, the same set of air supply pipes can only control the nozzle to move a fixed distance. If it is necessary to change the blowing depth, the position of the entire device needs to be adjusted, which is inconvenient to use. Therefore, a telescopic furnace sootblower is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a telescopic furnace soot blower, which aims to improve the problem in the prior art that "the existing gooseneck valve soot blower mainly relies on the air supply pipe to drive the nozzle to move, which is not convenient for adjusting the blowing depth".

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a telescopic furnace soot blower, comprising: Valve body, used to connect to the air supply device; A drive structure, used to provide power for the extension and retraction of the overall device, is installed on the upper surface of the valve body, and a transmission structure is installed on the upper surface of the valve body near the right end; An air supply pipe is installed on the outer wall of the valve body. An air guide pipe is installed on the outer wall of the air supply pipe. The air guide pipe is connected to the drive structure through a transmission structure. A jet assembly for guiding gas is disposed on the inner wall of an air guide tube. The jet assembly includes a sliding sleeve that is slidably connected to the inner wall of the air guide tube. A jet head is fixedly connected to the right end of the sliding sleeve. A protrusion is fixedly connected to the outer wall of the sliding sleeve. A groove is provided on the inner wall of the air guide tube, and the protrusion slides on the inner wall of the groove.

[0006] As a further description of the above technical solution: The jet assembly also includes a fixing sleeve, which is slidably connected to the inner wall of the jet head. An elastic telescopic rod is fixedly connected to the left end of the fixing sleeve, and the left end of the elastic telescopic rod is installed on the inner wall of the air guide tube.

[0007] As a further description of the above technical solution: The slide is provided in multiple sets, and the multiple sets of slides are arranged in a rotating array with the center line of the air guide pipe as the rotation axis. The lengths of the multiple sets of slides are different.

[0008] As a further description of the above technical solution: An adjusting screw is rotatably connected to the right side of the fixed sleeve, and the adjusting screw passes through and is threadedly connected to the right surface of the jet head.

[0009] As a further description of the above technical solution: The outer wall of the air duct is provided with an indicator mark.

[0010] As a further description of the above technical solution: The indicator is provided in multiple sets, one set of which is located on the outer wall of the jet head.

[0011] As a further description of the above technical solution: The left surface of the sliding sleeve is provided with grooves, and there are multiple sets of grooves.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by setting a movable jet assembly, when the gooseneck valve is ventilated, the gas will push the fixed sleeve to move the nozzle to the right. In this way, based on the movement of the air guide tube, the nozzle can be further moved. Thus, the movement depth of the jet head can be changed without moving the overall device, making the overall device more convenient to adjust.

[0013] 2. In this utility model, by setting multiple sets of sliding grooves of different lengths, when it is necessary to adjust the blowing depth, the sliding sleeve can be rotated by rotating the jet head, so that the protrusion can be driven into the sliding groove of different lengths. By changing the position of the protrusion, the additional extension range of the jet head and the sliding sleeve can be changed, and the overall device has good flexibility.

[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 1-3 One embodiment of this utility model is a telescopic furnace soot blower, comprising: Valve body 1 is used to connect to the gas supply device. In this application, valve body 1 is a gooseneck valve. Its bottom end can be connected to the gas supply device. It is hollow inside and can allow high-pressure gas to pass through. The drive structure 2, which provides power for the extension and retraction of the overall device, is installed on the upper surface of the valve body 1. The drive structure 2 mainly consists of a motor and a reducer. A transmission structure 3 is installed on the upper surface of the valve body 1 near the right end. The transmission structure 3 mainly consists of a gear set, a cam, a cam sleeve, etc. The gear set is connected to the output end of the reducer. Starting the motor will drive the transmission structure 3 to work. The reducer will drive the gear set in the transmission structure 3 to work. The gear set will drive the air guide pipe 4 to move to the right until the cam on the outer wall of the air guide pipe 4 engages with the cam sleeve in the transmission structure 3. During this process, the air guide pipe 4 will extend into the device to be cleaned. After the cam engages with the cam sleeve, the air guide pipe 4 will no longer move to the right, but will start to rotate. This allows for rotational cleaning. The transmission structure 3 and drive structure 2 mentioned in this application are inherent structures of gooseneck valve soot blowers in the prior art. This application does not improve the transmission structure 3 and drive structure 2, but only repeats the prior art. Moreover, those skilled in the art can implement them. Therefore, this application will not describe them in detail.

[0018] Reference Figure 2 , Figure 3 and Figure 6An air supply pipe 6 is installed on the outer wall of the valve body 1, allowing gas inside the valve body 1 to directly enter the interior of the air supply pipe 6. An air guide pipe 4 is installed on the outer wall of the air supply pipe 6 to guide the gas. The air guide pipe 4 is connected to the drive structure 2 via a transmission structure 3. The air guide pipe 4 can move on the outer wall of the air supply pipe 6, and air inside the air supply pipe 6 can directly enter the interior of the air guide pipe 4 through the connection point between the two. The jet assembly 5, used to guide gas, is disposed on the inner wall of the air duct 4. When the air duct 4 moves, the jet assembly 5 is also moved synchronously. The jet assembly 5 includes a sliding sleeve 51 for supporting the jet head 52, which is slidably connected to the inner wall of the air duct 4. There is no rigid connection between the sliding sleeve 51 and the air duct 4, so the sliding sleeve 51 can move or rotate inside the air duct 4. The right end of the sliding sleeve 51 is fixedly connected to the jet head 52 for guiding the gas ejection, and the outer wall of the sliding sleeve 51 is fixedly connected to a protrusion 54 for limiting the movement trajectory of the sliding sleeve 51. The inner wall of the air duct 4 is provided with a groove 42 for accommodating the protrusion 54, which slides on the inner wall of the groove 42. The sliding sleeve 51 is made of an elastic material and has good elastic deformation capability. When the operator rotates the sliding sleeve 51 forcefully, the left end of the sliding sleeve 51 can deform, thereby causing the protrusion 54 to disengage from the interior of the groove 42.

[0019] Reference Figures 4-6 The jet assembly 5 also includes a retaining sleeve 56, which is slidably connected to the inner wall of the jet head 52. The retaining sleeve 56 can slide left and right on the inner walls of the jet head 52 and the sliding sleeve 51. An elastic telescopic rod 55 is fixedly connected to the left end of the retaining sleeve 56, and the left end of the elastic telescopic rod 55 is installed on the inner wall of the air guide tube 4. When the retaining sleeve 56 is not under force, the elastic telescopic rod 55 will pull the retaining sleeve 56 to move it to the left and reset it. Multiple sets of sliding grooves 42 are provided, and the multiple sets of sliding grooves 42 are arranged in a rotating array with the center line of the air guide tube 4 as the rotation axis. By rotating the jet head 52, the sliding sleeve 51 can be rotated, and the rotation of the sliding sleeve 51 can drive the protrusion 54 to move. The multiple sets of sliding grooves 42 have different lengths. By controlling the protrusion 54 to be inserted into sliding grooves 42 of different lengths, the range of movement of the protrusion 54 and the sliding sleeve 51 can be changed. An adjusting screw 57 is rotatably connected to the right side of the fixed sleeve 56, which is used to move the fixed sleeve 56. The adjusting screw 57 passes through and is threaded onto the right surface of the jet head 52. By rotating the adjusting screw 57, the fixed sleeve 56 can be moved left and right. The fixed sleeve 56 is made of rigid material and cannot be deformed. When the left end of the fixed sleeve 56 is flush with the left end of the sliding sleeve 51, the left end of the sliding sleeve 51 will be restricted from bending inward.

[0020] Reference Figures 3-5The outer wall of the air guide tube 4 is provided with an indicator mark 41. Since both the protrusion 54 and the slide groove 42 are located inside the device, the current status of the device can be determined by observing the indicator mark 41 when adjustment is required. There are multiple sets of indicator marks 41, one set of which is located on the outer wall of the jet head 52. The relative positions of the air guide tube 4 and the outer wall of the jet head 52 can be determined by comparing the indicator marks 41 on the outer walls of the air guide tube 4 and the jet head 52. The left surface of the sliding sleeve 51 is provided with multiple sets of grooves 53. The multiple sets of grooves 53 make it easier for the left end of the sliding sleeve 51 to undergo elastic deformation.

[0021] Working principle: When this telescopic furnace soot blower is working, the drive structure 2 drives the air guide pipe 4 to move on the outer wall of the air delivery pipe 6 through the transmission structure 3, realizing the overall telescopic movement. At the same time, it can also drive the air guide pipe 4 to rotate one revolution. During the movement and rotation of the air delivery pipe 6, the jet assembly 5 will also move and rotate synchronously. The valve body 1 is connected to the air delivery device, so that high-pressure gas enters the air guide pipe 4 through the air delivery pipe 6. The gas pushes the fixed sleeve 56 to drive the jet head 52 and the sliding sleeve 51 to extend to the right, increasing the blowing depth based on the movement of the air guide pipe 4. After the gas pressure disappears, the elastic telescopic rod 55 pulls the fixed sleeve 56 to reset.

[0022] When the blowing depth needs to be adjusted, the rotating jet head 52 drives the sliding sleeve 51, causing the protrusion 54 to disengage from the current sliding groove 42 and engage with sliding grooves 42 of different lengths. After the position of the protrusion 54 is adjusted, the adjusting screw 57 can be rotated to move the fixing sleeve 56 to the left. The fixing sleeve 56 will support the inner wall of the sliding sleeve 51, limiting the deformation of the sliding sleeve 51. The indicator mark 41 on the outer wall of the air guide tube 4 and the jet head 52 can help determine the relative position. The groove 53 on the left surface of the sliding sleeve 51 makes it easy to deform elastically, which makes it easy for the protrusion 54 to switch into different sets of sliding grooves 42.

[0023] 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.
