Description

Fixed fully-sealed solid waste incineration device

Technical field

[0001] The present utility model relates to the technical field of solid waste incineration treatment, and specifically relates to a transformation of a sintering machine into a fixed fully sealed solid waste incineration device.

Background technique

[0002] Sintering machines are generally divided into belt type, stepping type and box type. The belt type sintering machine has a large output and a high degree of automation. There are movable slides and fixed slides, the solid air leakage rate is quite large, generally reaching 40~60%, and the energy consumption is high. The whole process from loading to unloading of the incineration box of the box sintering machine is carried by crane, manual hooking, and there are many links. Since the incineration box and the wind box of the box sintering machine are separated, the crane is hoisted to the upper end of the wind box to ignite and sinter. After sintering, , The incinerator is hoisted to the crusher by a crane, and then overturned and broken, and then transferred to the buffer warehouse for installation, the air leakage rate is relatively high.

[0003] The incineration box and the wind box of some existing incinerators adopt soft connection, that is, the cylinder connection. This connection can reduce the air leakage rate of the incineration box and the wind box. However, this connection method also has drawbacks. When the air pressure is distributed to each cylinder When the pressure of each cylinder cannot be uniform, there will be the possibility of air leakage. In addition, the incinerator is deformed due to high temperature, which may also lead to poor contact after deformation and air leakage. Utility model content

[0004] In view of the deficiencies of the prior art, the present utility model proposes a fixed fully sealed solid waste incinerator to solve the problem of air leakage between the incineration box and the wind box. The specific technical solutions are as follows:

[0006] The wind box is located below the incineration box and communicates with the incineration box, and a first sealing ring is provided where the incineration box communicates with the wind box;

[0007] The residue box is located below the wind box and is in communication with the wind box, and a second sealing ring layer is further provided where the wind box communicates with the residue box;

[0008] A scraper mechanism is provided below the residue box, and a suction pipe is connected to the side wall of the wind box.

[0009] When in use, after the solid waste in the incinerator is ignited, under the action of negative pressure, the solid waste starts to burn gradually from top to bottom until all the combustion is completed. After the negative pressure of the wind box is turned off, the residue box is opened, and then Open the flip grate and the scraper mechanism, the residue will fall on the scraper mechanism through the residue box, and the solid waste will be transported to the residue bin through the scraper mechanism.

[0010] In order to better realize the utility model, further, the wind box and the incineration box are connected by bolts and nuts; the residue box and the wind box are connected by bolts and nuts.

[0011] Further, the first sealing ring and the second sealing ring layer are both asbestos plate sealing rings.

[0012] Further, the bellows has a V-shaped structure.

[0013] Further, the exhaust pipe is provided with an air control valve at a position connected to the wind box.

[0014] Further, an upper valve is provided on the upper part of the side wall of the residue box, and a lower valve is provided on the lower part of the side wall of the residue box.

[0015] Further, the turning grate bar adopts a high-chromium cast iron grate bar or a heat-resistant steel grate bar to extend the service life of the incinerator.

[0016] Compared with the prior art, the beneficial effects of the present utility model are: the traditional sintering machine is converted into a solid waste incineration device, and the incineration box and the wind box are connected as a whole, and the screw and nut are used to cooperate and connect, which completely solves the problem of incineration. There is a problem of air leakage between the box and the wind box. After the incineration is completed, the scraper mechanism is used to transport the burned slag, which reduces labor intensity and reduces safety hazards; using negative pressure incineration technology, the residue collection equipment is sealed, so that the environment is not affected.
