Description

Technical Field

[0001] This utility model belongs to the field of boiler technology, and specifically relates to an anti-clogging slag discharge structure. Background Technology

[0002] A boiler is an energy conversion device, mainly used to heat water to the required temperature or convert it into steam for various industrial and civil applications. During the combustion process, boilers produce ash and slag, especially coal-fired boilers. If this ash and slag is not cleaned in time, it may cause blockage of the ash discharge system and affect the normal operation of the boiler.

[0003] Existing anti-clogging slag discharge structures use vibrators to generate periodic vibrations, causing the ash and slag adhering to the slag discharge channel walls to loosen and fall, thereby preventing blockages during boiler slag discharge. However, in actual use, due to the need to avoid damage to the boiler caused by vibration, the vibration effect of the vibrator is limited. This results in some boiler slag still arching and blocking during the slag discharge process, requiring staff to use hand tools to assist in unblocking it, which places a certain workload on the personnel. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an anti-clogging slag discharge structure. By rotating the fixed rod and the top material rack on the fixed rod, the fixed rod and the top material rack on the fixed rod move up and down repeatedly. The fixed rod and the top material rack on the fixed rod penetrate into the boiler to support the slag inside, thereby clearing the slag and facilitating material discharge, thus preventing clogging.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an anti-clogging slag discharge structure, including a slag discharge cylinder, a movable cylinder slidably arranged inside the slag discharge cylinder, a fixed rod arranged inside the movable cylinder through a support plate, a top material frame arranged at the top of the fixed rod, and vertically evenly distributed inclined plates arranged on the outer side of the fixed rod. A rotating seat is arranged on the inner wall of the slag discharge cylinder, and a rotating cylinder is rotatably arranged inside the rotating seat. A fixed sleeve is arranged on the outer side of the movable cylinder, and multiple sliding columns are arranged on the outer side of the fixed sleeve. The sliding columns are all slidably connected to the rotating cylinder. A driving mechanism is arranged on the slag discharge cylinder to drive the top material frame to move. Multiple support legs are arranged on the lower side of the slag discharge cylinder, and a fixed plate is arranged on the lower surface of each support leg. A fixing hole is opened on each fixed plate.

[0006] As a further improvement of this utility model, the driving mechanism includes a bevel gear one fixedly sleeved on the lower side of the outer arc surface of the rotating cylinder, a bevel gear two rotatably arranged on the inner wall of the slag discharge cylinder via a rotating shaft, and the bevel gear two meshing with the bevel gear one; a motor is arranged on the outer side of the slag discharge cylinder, and the output shaft of the motor is fixed to the rotating shaft by a coupling; multiple roller seats are arranged on the lower surface of the sliding column, and V-groove rollers are rotatably arranged inside the roller seats; a guide rail is arranged on the lower side of the inner wall of the slag discharge cylinder, and the V-groove rollers are all installed in conjunction with the V-groove rollers.

[0007] As a further improvement of this utility model, the inner wall of the movable cylinder and the outer side of the top material rack and the inclined plate are all provided with a ceramic coating.

[0008] As a further improvement of this utility model, a control box is provided on the outside of the slag discharge cylinder, and the motor is electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the moving cylinder, fixed rod, and the top material rack and inclined plate on the fixed rod move up and down repeatedly during rotation, allowing the fixed rod and the top material rack on the fixed rod to penetrate into the boiler to support the slag inside, clear the slag, facilitate material discharge, and prevent blockage.

[0011] Secondly, the motor operation is controlled by the control box. The output shaft of the motor drives the second bevel gear connected to it to rotate. Through the meshing relationship between the second bevel gear and the first bevel gear, the rotating drum where the first bevel gear is located is driven to rotate. This causes the fixed rod and the top material rack and inclined plate set on the fixed rod to rotate with the rotation of the moving drum.

[0012] Thirdly, during the rotation of the movable cylinder, the roller seat on its lower side is driven by the sliding column to rotate together. Through the constantly undulating guide rail, the V-groove roller drives the sliding column and the rotating cylinder to move up and down reciprocally. This causes the movable cylinder, the fixed rod, and the top material frame and inclined plate set on the fixed rod to move up and down reciprocally during the rotation.

[0013] Fourth, by passing bolts through the fixing holes on the fixing plate and tightening the bolts with external tools, the slag discharge cylinder can be fixed in the designated position, which can effectively prevent the position of the slag discharge cylinder from easily moving during use.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the device includes a slag discharge cylinder 101, a movable cylinder 102 slidably disposed inside the slag discharge cylinder 101, a fixed rod 105 disposed inside the movable cylinder 102 via a support plate, a top material frame 106 disposed at the top of the fixed rod 105, and vertically evenly distributed inclined plates 107 disposed on the outer side of the fixed rod 105. A rotating seat 201 is disposed on the inner wall of the slag discharge cylinder 101, and a rotating cylinder 202 is rotatably disposed inside the rotating seat 201. A fixed sleeve 203 is disposed on the outer side of the movable cylinder 102, and multiple sliding columns 204 are disposed on the outer side of the fixed sleeve 203. The sliding columns 204 are all slidably connected to the rotating cylinder 202. A driving mechanism is disposed on the slag discharge cylinder 101, which is used to drive the top material frame 106 to move. The inner wall of the movable cylinder 102 and the outer sides of the top material frame 106 and the inclined plates 107 are all coated with ceramic coating.

[0022] like Figure 2 , 4 As shown, the drive mechanism includes a bevel gear 205 fixedly sleeved on the lower side of the outer arc surface of the rotating drum 202, a bevel gear 206 rotatably mounted on the inner wall of the slag discharge cylinder 101 via a rotating shaft, and the bevel gear 206 meshing with the bevel gear 205; a motor 207 is mounted on the outer side of the slag discharge cylinder 101, and the output shaft of the motor 207 is fixed to the rotating shaft via a coupling.

[0023] like Figure 3 ,4 As shown, the lower surface of the sliding column 204 is provided with multiple roller seats 208, and V-groove rollers 209 are rotatably installed inside the roller seats 208. The lower side of the inner wall of the slag discharge cylinder 101 is provided with a guide rail 210, and the V-groove rollers 209 are all installed in conjunction with the V-groove rollers 209.

[0024] like Figure 1 As shown, a control box 301 is installed on the outside of the slag discharge cylinder 101, and the motor 207 is electrically connected to the control box 301.

[0025] In use, the motor 207 is controlled by the control box 301. The output shaft of the motor 207 drives the bevel gear 206 connected to it to rotate. Through the meshing relationship between the bevel gear 206 and the bevel gear 205, the rotating drum 202 where the bevel gear 205 is located is rotated. The rotating drum 202 drives the movable cylinder 102 where the fixed sleeve 203 is located to rotate through the sliding column 204. The movable cylinder 102 drives the fixed rod 105 inside it to rotate. In turn, the fixed rod 105 and the top material frame 106 and inclined plate 107 on the fixed rod 105 rotate with the rotation of the movable cylinder 102.

[0026] During the rotation of the movable cylinder 102, the roller seat 208 on its lower side is driven by the sliding column 204 to rotate together, which in turn causes the roller seat 208 to drive the V-groove roller 209 to move on the guide rail 210. Through the constantly undulating guide rail 210, the V-groove roller 209 drives the sliding column 204 and the rotating cylinder 202 to move up and down reciprocally, which in turn drives the movable cylinder 102, the fixed rod 105 and the top material frame 106 and the inclined plate 107 set on the fixed rod 105 to move up and down reciprocally during the rotation.

[0027] As the movable cylinder 102, fixed rod 105, and the top material rack 106 and inclined plate 107 on the fixed rod 105 rotate, they move up and down repeatedly, allowing the fixed rod 105 and the top material rack 106 on the fixed rod 105 to penetrate into the boiler and support the slag inside, clearing the slag to facilitate material discharge and prevent blockage. The slag falling into the movable cylinder 102 is facilitated to be discharged smoothly by the rotation of the movable cylinder 102 and the rotation of the inclined plate 107 on the fixed rod 105.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2As shown, the lower side of the slag discharge cylinder 101 is provided with multiple support legs 103, and the lower surface of each support leg 103 is provided with a fixing plate 104, and each fixing plate 104 is provided with fixing holes. In use, after passing bolts through the fixing holes on the fixing plate 104, the bolts are tightened by external tools, thereby fixing the slag discharge cylinder 101 in the designated position, which can effectively prevent the position of the slag discharge cylinder 101 from easily moving during use.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
