Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of boiler, in particular to a dust reduction and conveying device for boiler slag. BACKGROUND

[0002] The boiler is an energy conversion device, and the energy input into the boiler includes chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. According to the classification of the boiler according to the types of fuel used, the boiler can be divided into coal-fired boilers, oil-fired boilers and gas-fired boilers. The existing coal-fired boiler often uses coal as energy in the use process. After the coal is burned, the coal slag, also known as slag, is left. The slag needs to be transported and uniformly stored and processed after cooling.

[0003] The slag after the boiler is burned is directly discharged from the bottom of the furnace. After cooling, the slag is transported to the storage mechanism by the conveying device. However, the fine dust is easily stirred up during the falling of the slag. Since the ash particles are fine particles, the dust is easily scattered to pollute the air. SUMMARY

[0023] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0024] The embodiment of the present application provides a dust reduction and conveying device for boiler slag, which is used for avoiding air pollution caused by dust splashing of the slag during storage and conveying.

[0025] In addition, the embodiments shown below do not have any limiting effect on the invention content recited in the claims. In addition, the entire content of the configuration represented by the following embodiments is not limited to being necessary for the solution of the invention recited in the claims.

[0026] Please refer to Figure 1 The dust reduction and conveying device for boiler slag in the embodiment of the present application comprises a feeding box 1, a storage box 2 and a conveying mechanism 3. The feeding box 1 comprises a first cavity 4 and a second cavity 5. The first cavity 4 is provided with a first funnel 6 at the top end. The second cavity 5 is provided with a second funnel 7 at the bottom end. The bottom end of the first cavity 4 is provided with a discharging plate 8. The discharging plate 8 is arranged on one side of the second funnel 7. One end of the discharging plate 8 faces the second funnel 7. The top end of the first cavity 4 is provided with a water spraying pipe 9. The first funnel 6 is provided with a speed reduction mechanism 10 inside. The bottom of the second funnel 7 is connected with the conveying mechanism 3. The conveying mechanism 3 is provided with a conveying shaft 11 with spiral blades inside. The conveying shaft 11 is used for uniformly conveying the slag in the feeding box 1 to the storage box 2. After the slag is discharged from the boiler, the slag enters the first funnel 6. The speed reduction mechanism 10 in the first funnel 6 reduces the falling speed of the slag, so that the slag slowly falls on the discharging plate 8, avoiding splashing a large amount of dust due to high-speed impact of the slag on the discharging plate 8. The water spraying pipe 9 sprays a small amount of water on the slag, so that the slag is wetted, and then falls into the conveying mechanism 3 through the second funnel 7, avoiding blowing up of the dust on the surface of the slag by the wind during conveying. The conveying mechanism 3 carries the slag to the storage box 2. The air pollution caused by splashing of the dust of the slag during storage and conveying is effectively avoided.

[0027] The speed reduction mechanism 10 comprises a plurality of buffer plates 12. The inner walls on both sides of the first funnel 6 are alternatively hinged with the plurality of buffer plates 12. The connection between the buffer plate 12 and the first funnel 6 is hinged through a torsional spring. After the slag enters the first funnel 6, the plurality of buffer plates 12 guide the slag and the torsional spring buffers the slag, so that the falling speed of the slag is reduced, avoiding splashing a large amount of dust when the slag falls on the discharging plate 8.

[0028] A plurality of atomizing nozzles are obliquely arranged on the outer wall of the water spraying pipe 9, and the openings of the atomizing nozzles all face the bottom of the first funnel. The water spraying pipe 9 uniformly sprays water to the surface of the slag through the plurality of atomizing nozzles, and the atomized water droplets can perform dust-settling treatment on a small amount of dust floating in the air.

[0029] A dustproof screen 13 is arranged between the inner walls of the side of the feeding box 1 away from the storage box 2, and the bottom of the dustproof screen 13 closely abuts the outer side of the conveying mechanism 3, so as to further avoid dust from floating in all directions when entering the second funnel 7.

[0030] The atomizing nozzles are uniformly arranged along the inner walls of the four sides of the first cavity 4, so that the water mist is more uniformly sprayed on the slag, and dust in the feeding box 1 is effectively settled.

[0031] The discharging plate 8 comprises a discharging plate body 14 and a support 15, the discharging plate body 14 is rotatably connected with the support 15, and a vibrator 16 is fixedly arranged at the bottom of the discharging plate body 14. After the slag falls onto the discharging plate 8, the discharging plate 8 is regularly vibrated by the vibrator 16, which is beneficial to the slag on the discharging plate body 14 to automatically fall into the second funnel 7, and solves the problem of slag retention on the discharging plate body 14 to cause blockage.

[0032] The top surface of the discharging plate body 14 is of an inclined structure, which is beneficial to the low end of the discharging plate body 14 to extend into the second funnel 7, and baffles are arranged at the two side edges of the discharging plate body 14. The two baffles are used for laterally shielding the slag to prevent the slag from laterally sliding down from the discharging plate body 14.
