Description

Technical Field

[0001] The utility model belongs to the technical field of collection devices, and particularly relates to a collection device for boiler slag discharge. Background Art

[0002] During the combustion of coal or other fuels in a boiler, a large amount of slag is generated. The slag contains high-temperature substances and residual unburned fuel. If not removed in time, it may block the slag discharge channel, causing the internal pressure of the boiler to rise abnormally and even leading to safety accidents such as explosions in severe cases. Therefore, the collection device for boiler slag discharge is an indispensable part of the boiler system. In the prior art, a slag discharge slide plate is arranged between the boiler and the collection mechanism, and a mechanism for hitting the slag discharge slide plate is arranged below the slag discharge plate to make the slag discharge slide plate shake. However, in this way, the long-term hitting operation may cause wear of the slag discharge slide plate and the transmission rod, reducing the service life of the equipment and increasing the maintenance cost.

[0003] For example, the utility model with the publication number CN217274207U discloses a biomass boiler slag collection device. In the technical solution of this patent, a furnace body is arranged at the left end of the upper surface of a base plate, and a collection mechanism is arranged at the right end. A slag discharge slide plate is arranged between the furnace body and the collection mechanism, and a shaking mechanism is arranged below the slag discharge slide plate. The shaking mechanism is that a disc drives an eccentric rod to rotate, and the eccentric rod drives a transmission rod to move so as to make the slag discharge slide plate shake. The continuous hitting action will accelerate the mechanical wear of the slag discharge slide plate, the transmission rod and their connecting components. In the long run, it may cause the strength of these components to decrease, deform or even break. Summary of the Utility Model

An ash discharge chamber is arranged inside the furnace body 102. An ash discharge port 103 is formed on the right side wall of the furnace body 102. A discharge plate 104 is arranged on the left side wall of the ash discharge chamber. A slag discharge assembly is arranged below the discharge plate 104. A shaking assembly for shaking the slag discharge assembly is arranged on the right side wall of the furnace body 102.

[0023] As Figure 1 , 2 shown, the slag discharge assembly includes a fixing frame 105 arranged below the discharge plate 104. A rotating column 106 is rotatably arranged in the middle of the fixing frame 105. A slag discharge plate 107 is arranged on the rotating column 106. One side of the slag discharge plate 107 away from the rotating column extends into the inner cavity of the collection mechanism. Baffles 108 are arranged on both sides of the slag discharge plate 107. The arranged baffles 108 can effectively prevent the furnace slag from overflowing from both sides of the slag discharge plate 107, prevent the furnace slag from splashing, and reduce environmental pollution and equipment loss.

[0024] As Figure 1 , 3 shown, the shaking assembly includes a square plate 201 arranged below the slag discharge plate 107. A sliding rod 202 is rotatably connected to the lower end of the square plate 201. A support frame 203 is arranged on the right side wall of the furnace body 102. The lower end of the sliding rod 202 is slidably connected to the inside of the support frame 203. A circular plate 204 is arranged at the lower end of the sliding rod 202. A spring 205 is sleeved on the middle of the sliding rod 202. One end of the spring 205 is connected to the upper side wall of the support frame 203, and the other end is connected to the upper side wall of the circular plate 204. A roller 206 is arranged on the lower side of the circular plate 204. A driving member for driving the roller 206 to move is arranged at the left end of the support frame 203. The driving member includes a strip plate 207 arranged at the upper end of the connecting frame. An adjusting block 208 is slidably arranged at the upper end of the strip plate 207. A telescopic push rod 209 is fixedly arranged on the left side of the support frame 203. The output end of the telescopic push rod 209 passes through the left side wall of the support frame 203 and is connected to the adjusting block 208. Starting the telescopic push rod 209 makes the adjusting block 208 move back and forth along the strip plate 207, so that the roller 206 makes a vertical movement on the adjusting block 208, so as to make the roller 206 drive the sliding rod 202 to make a vertical movement on the support frame 203, thereby driving the square plate 201 to drive the slag discharge plate 107 to make a vertical movement, and then realizing the shaking of the slag discharge plate 107. Continuous shaking helps to break the formed ash slag layer into small pieces, promote the smooth sliding of the slag particles, and improve the slag discharge speed and efficiency.

[0025] As Figure 1 , 4As shown in the figure, the collection mechanism includes a collection box 301 arranged on the upper right side of the bottom plate 101.

The output end of the hydraulic cylinder 304 passes through the upper side wall of the collection box 301 and is connected with a pressing plate 305 for compacting the slag. Starting the hydraulic cylinder 304 can make the pressing plate 305 move downward to extrude and compact the slag, which can significantly reduce the occupied space volume and improve the space utilization rate of the collection box 301.

[0027] Working principle: When using this device for slag discharge and collection, the slag generated by combustion inside the furnace body 102 falls onto the upper surface of the slag discharge plate 107 through the discharge plate 104. Then, start the telescopic push rod 209 to make the adjusting block 208 move back and forth along the strip plate 207, and further make the roller 206 move up and down on the adjusting block 208, so as to drive the sliding rod 202 to move up and down on the support frame 203, thereby driving the square plate 201 to drive the slag discharge plate 107 to move up and down, and then realizing the shaking of the slag discharge plate 107. The continuous shaking helps to break the formed ash layer into small pieces, promote the smooth sliding of the slag particles, improve the slag discharge speed and efficiency. The fallen slag enters the interior of the collection box 301 through the slag discharge plate 107. Then, starting the hydraulic cylinder 304 can make the pressing plate 305 move downward to extrude and compact the slag, which can significantly reduce the occupied space volume and improve the space utilization rate of the collection box 301, thus achieving the purpose of collecting the slag.
