Description

Technical Field

[0001] This utility model belongs to the field of boiler ash discharge technology, and specifically relates to a dust prevention device for boiler ash discharge. Background Technology

[0002] A boiler is a device that heats water into steam or hot water by burning fuel or other energy sources. It is widely used in heating, power generation, industrial production and other fields. Boiler ash removal is an important part of the operation of coal-fired boilers. It mainly refers to the process of removing and treating the ash produced after fuel combustion from the furnace. A reasonable ash removal system directly affects the boiler's efficiency, safety and environmental protection.

[0003] Existing dust control devices for boiler ash discharge connect a dust collection box to the boiler above. When the boiler discharges ash, the ash falls directly through the inside of the dust collection box. During this process, a fan installed on the dust collection box blows the dust generated by the falling ash to one side for collection. However, in practice, the atomizing nozzles are mostly not positioned correctly when collecting dust. When the dust is sprayed with dust-suppressing water through the atomizing nozzles, the dust cannot quickly and evenly come into full contact with the atomized dust-suppressing water, resulting in poor dust collection and treatment efficiency. This may lead to some dust leakage and environmental impact. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a dust suppression device for boiler ash removal. By driving the atomizing nozzle on the dust removal pipe to swing up and down repeatedly, the atomized dust-suppressing water can quickly and evenly suppress dust, thus efficiently and rapidly suppressing the dust generated during boiler ash removal.

Multiple sliding columns are disposed on the outer side of each drive seat. The sliding columns are slidably connected to adjacent drive grooves. Symmetrically distributed electric push rods are disposed inside the drive box. The telescopic ends of the electric push rods are connected and fixed to adjacent drive seats.

[0008] As a further improvement of this utility model, a control box is provided on the outside of the dust collection box, and the fan and electric push rod are 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 material discharged from the boiler enters the dust collector through the hopper. Then, the material is guided and buffered by the chute plate 1 and chute plate 2 installed on the inner wall of the dust collector, which allows the material to be discharged smoothly from the hopper while preventing it from breaking.

[0011] Secondly, the fan blows the dust accompanying the falling material toward the waste hopper, and the external water tank conveys dust-suppressing water inside the conveying pipe, so that the dust-suppressing water can atomize and suppress the dust blown in.

[0012] Thirdly, during the operation of the fan, the telescopic end of the electric push rod continuously extends and retracts in a cycle, causing the rotating shaft to drive the atomizing nozzle on the dust removal pipe to swing up and down repeatedly, so that the atomized dust-suppressing water can quickly and evenly suppress dust, and can efficiently and rapidly suppress dust generated during boiler slag discharge.

[0013] Fourth, by passing bolts through the fixing holes on the fixing plate and tightening them with external tools, the dust collector can be stably fixed in the designated position, which can effectively prevent the position of the dust collector from easily moving during the boiler ash discharge process.

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 1 , 2 As shown, the dust collector includes a dust collection box 103. Multiple support plates 301 are provided on both inner walls of the dust collection box 103. Dust collection pipes 302 are rotatably installed between adjacent support plates 301. Multiple atomizing nozzles 303 are provided on the outer side of each dust collection pipe 302. A conveying pipe 304 is installed on the outer side of the dust collection box 103 via a clamp. A telescopic pipe 305 is provided between the conveying pipe 304 and the adjacent dust collection pipe 302. A driving mechanism is also provided on the dust collection box 103 to drive the atomizing nozzles 303 to swing. A first strainer 104 is provided at the air inlet on the outer side of the dust collection box 103. A partition 105 is provided inside the dust collection box 103. A second strainer 106 is provided in the middle of the partition 105. A fan 107 is provided between the first strainer 104 and the second strainer 106.

[0022] like Figure 3 , 4As shown, the drive mechanism includes a drive box 306 located outside the dust collector 103. Multiple rotating shafts 307 are rotatably mounted inside the drive box 306. Each rotating shaft 307 is fixed to an adjacent dust collector pipe 302 via a coupling. A rotating seat 308 is fixedly fitted onto the outer side of each rotating shaft 307. Each rotating seat 308 has a drive groove 309. Multiple guide rails 310 are located inside the drive box 306. Symmetrically distributed drive seats 311 are slidably mounted between the guide rails 310. Multiple sliding columns are located on the outer side of each drive seat 311, and these columns are slidably connected to adjacent drive grooves 309. Symmetrically distributed electric push rods 312 are located inside the drive box 306. The telescopic ends of the electric push rods 312 are connected and fixed to adjacent drive seats 311.

[0023] like Figure 2 , 4 As shown, a hopper 201 is provided at the discharge port at the upper end of the dust collector 103, a funnel 204 is provided at the discharge hopper at the lower surface of the dust collector 103, a waste hopper 205 is provided at the liquid discharge port at the lower surface of the dust collector 103, and multiple vertically evenly distributed chute plates 202 and 203 are provided inside the dust collector 103.

[0024] like Figure 1 , 2 As shown, a control box 401 is installed on the outside of the dust collection box 103, and the fan 107 and the electric push rod 312 are both electrically connected to the control box 401.

[0025] In use, the control box 401 controls the operation of the fan 107 and the electric push rod 312 to connect the conveying pipe 304 to the external water source. Then, the material discharged from the boiler enters the dust collector 103 from the hopper 201. The material is then guided and buffered by the chute plate 202 and chute plate 203 set on the inner wall of the dust collector 103. This allows the material to be discharged smoothly from the funnel 204 while preventing it from breaking.

[0026] The blower 107 blows the dust accompanying the falling material toward the waste hopper 205; the external water supply tank conveying pipe 304 delivers dust-suppressing water, which is then fed into the dust removal pipe 302 through the telescopic pipe 305 and sprayed out through the atomizing nozzle 303 on the dust removal pipe 302, allowing the dust-suppressing water to atomize and suppress the blown dust; during the operation of the blower 107, the telescopic end of the electric push rod 312 continuously extends and retracts in a cycle, causing the electric push rod 312 to drive the drive seat 311 between the guide rails 310. During the movement of the drive seat 311, the sliding column set on it is driven by the drive seat 311 to slide inside the drive groove 309. This causes the drive seat 311 to drive the rotating shaft 307 where the rotating seat 308 is located to rotate back and forth through the cooperation of the sliding column and the drive groove 309. In turn, the rotating shaft 307 drives the atomizing nozzle 303 on the dust removal pipe 302 to swing up and down, so that the atomized dust-suppressing water can quickly and evenly suppress dust. This can efficiently and rapidly suppress dust generated during the boiler ash discharge process.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a bracket 101 is provided on the lower side of the dust collector 103, and symmetrically distributed fixing plates 102 are provided on the lower surface of the bracket 101. In use, the dust collector 103 can be stably fixed in the designated position by bolts passing through the fixing holes on the fixing plates 102 and tightening them with external tools, which can effectively prevent the position of the dust collector 103 from easily moving during the boiler ash discharge process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any 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.
