Description

Technical Field

[0001] The utility model relates to the technical field of industrial kilns, and in particular to a dust cleaning device for industrial kilns. Background Art

[0002] Industrial kiln is a heating equipment used in industrial production. Its main function is to heat raw materials to a certain temperature and undergo physical or chemical changes. This equipment is widely used in metallurgy, chemical industry, building materials, ceramics, glass, electronics, food and other industries. It is mainly used to achieve sintering, smelting, roasting, drying, carbonization, vulcanization, oxidation and other processes.

[0003] The internal structure of industrial kilns is complex, and ash may accumulate in many parts. The furnace structure of the kiln is complex, especially in those corners that are difficult to clean. Ash is easy to accumulate. These ashes are mainly formed by the residues of combustion materials. When the combustion residues gather in the furnace, ash will be formed. Some dust will settle downward and fall into the slag box. At the same time, some dust will move upward with the flue gas and adhere to the inner wall of the kiln, so it is necessary to clean it regularly.

[0004] In the prior art, a Chinese patent for an industrial kiln dust cleaning device (publication number CN211012474U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: through the exhaust of the fan, the dust and dust are sucked out of the kiln with the air through the exhaust pipe, and then passed into the filter box in the water tank through the metal hose. The dust and dust are filtered through the filter net and fall into the dust collection box, avoiding the need to manually enter the kiln for cleaning, thereby improving the safety of the staff and reducing the labor intensity of the workers. However, in the actual operation process, the various slags generated during the combustion of the kiln are difficult to completely remove only by air pressure, especially some dust adhering to the inner wall of the kiln, which is difficult to effectively extract only by the action of air pressure. Some of these dusts are residues generated after the combustion of the material. They not only adhere to the inner wall of the kiln, but also gradually accumulate and form stubborn dirt over time. These dirts are usually difficult to remove by conventional air pressure cleaning methods, and it is difficult to achieve an ideal cleaning effect. Utility Model Content

[0047] The working principle of the ash cleaning device for industrial kilns is described in detail below.

[0048] like Figure 1-Figure 6As shown, dust is generated during the operation of an industrial kiln, and some of the dust will settle downward and fall into the slag box. At the same time, some of the dust will move upward with the smoke and adhere to the inner wall of the kiln. When cleaning the dust on the inner wall of the kiln, first hold the handle 1 by hand, extend the shell 4 into the kiln, place the side of the brush plate 28 with bristles close to the inner wall of the kiln, and control the motor 7 to work, so that the hollow shaft 14 is driven to rotate through the first bevel gear 17 and the second bevel gear 18, and then the brush plate 28 is rotated.

When the piston plate 9 moves to the side close to the slide rod 11, the one-way valve in the input pipe is connected, and the one-way valve in the output pipe is blocked at this time, so that the driving cylinder 6 draws air to the hollow shaft 14 through the input pipe (and the dust extraction pipe 19), so that negative pressure is generated in the brush plate 28, and dust is extracted through the through hole 21, so that the dust passes through the brush plate 28 and the hollow shaft 14, and then is sucked into the driving cylinder 6 through the input pipe; when The piston plate 9 moves to the side away from the slide rod 11, and the one-way valve in the input pipe is blocked, while the one-way valve in the output pipe is turned on, so that the driving cylinder 6 exhausts air to the bellows 20 through the output end, and discharges the dust to the collecting bucket 2 through the grip 1. The dust is discharged into the water, which can cool it down on the one hand and prevent it from being raised again on the other hand. An exhaust hole and a filter are provided on the top of the collecting bucket 2, and the air discharged to the collecting bucket 2 is also discharged from the exhaust hole, and the dust is continuously discharged and collected with the continuous rotation of the cam 15.

[0049] The cleaning process should be carried out when the temperature inside the kiln is lowered to a level that will not cause harm to personnel or equipment, and direct high-temperature operations should be avoided.

[0050] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
