[0044] A vertical baffle 25 is fixedly arranged at the left and right ends of the front end surface of the dust cleaning box 2 respectively. The baffle 25 is made of rubber.
[0045] The working principle of the present utility model is as follows:
[0046] The lifting device is used to drive the hanging basket 1 to lift and move horizontally, so that the middle fixed brush 9 and the outer sliding brush 15 on the dust cleaning box 2 are in contact with the inner wall of the furnace. At this time, the two side baffles 25 and the lower dust suction hopper 6 are in flexible contact with the inner wall of the furnace.
[0047] The control drive motor 17 starts to run. The drive motor 17 drives the middle rotating shaft to rotate through the synchronous belt transmission mechanism 18. The middle rotating shaft drives the middle fixed brush 9 to rotate. The middle rotating shaft drives the outer rotating shafts on both sides to rotate through the universal joints 16 at both ends. The outer rotating shafts drive the outer sliding brushes 15 to rotate. The rotating middle fixed brush 9 and outer sliding brush 15 sweep the dust on the inner wall of the furnace.
[0048] Meanwhile, control the fan 20 and the dust suction motor 24 to start running. The fan 20 injects air into the air blowing box 5 through the air blowing pipe 19. The air blowing box 5 blows air towards the rotary brush through a row of air blowing ports at the lower end, ensuring that the dust cleaned by the middle fixed rotary brush 9 and the outer sliding rotary brush 15 is blown below the middle fixed rotary brush 9 and the outer sliding rotary brush 15 and enters the dust suction hopper 6. The dust suction motor 24 drives the fan to rotate inside the action shell 23, so that the dust inside the dust suction hopper 6 is sucked into the dust collection box 21 through the dust suction pipe 22 for storage.
[0049] When an abnormal protrusion appears inside the furnace, the outer sliding rotary brushes 15 on both sides start to rotate towards the inside of the ash cleaning box 2 under the action of the abnormal protrusion, and the buffer spring 13 is compressed, so that the outer sliding rotary brushes 15 are in contact with the abnormal protrusion. Since the middle rotating shaft and the outer rotating shaft are connected by a universal joint 16, the rotation of the outer sliding rotary brush 15 does not affect its normal rotation when it rotates.
[0050] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
