Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis, in particular to an integrated device for preventing blockage of gas and slag discharge. Background Technique

[0002] The reaction process in which substances decompose when heated. Many inorganic and organic substances will undergo decomposition reactions when heated to a certain extent. In the past, the pyrolysis process did not involve catalysts and other energies, such as reactions caused by ultraviolet radiation. Currently, due to factors such as improving pyrolysis efficiency, increasing the yield of pyrolysis products, and preparing products that are not easily prepared by conventional pyrolysis, more and more research has been carried out on catalytic pyrolysis by adding catalysts during the pyrolysis process. Some catalytic pyrolysis processes, such as adding catalysts such as CaO and MgO in plastic pyrolysis, have been used in industrial production.

[0003] Waste rubber, plastics, and rubber powder all belong to pyrolysis raw materials. Generally, pyrolysis equipment is used for processing. The furnace slag generated by pyrolysis needs to be discharged through the slag outlet, and it is easy for the slag outlet to be blocked by relatively large and incompletely pyrolyzed raw materials, affecting slag discharge and gas exhaust. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated device for preventing blockage of gas and slag discharge to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An integrated device for preventing blockage of gas and slag discharge is arranged inside the furnace body and at the inner end of the furnace body. The integrated device for preventing blockage of gas and slag discharge is connected to the inner side of the furnace body and the screw conveyor discharge pipe arranged on the furnace body. The screw conveyor discharge pipe penetrates through the gas and slag discharge opening formed on the furnace body, and the upper and lower openings form a tee. The upper opening is used for gas discharge, and the lower opening is used for slag discharge. The integrated device for preventing blockage of gas and slag discharge includes:

[0007] An annular end cover fixed on the furnace body and a plurality of inclined plates fixed circumferentially along the annular end cover. A material guiding groove is formed between two adjacent inclined plates in two groups, and the material guiding groove is connected to the screw conveyor discharge pipe.

[0008] For the integrated device for preventing blockage of gas and slag discharge as described above: A spherical panel is fixed on the side of the inclined plate away from the annular end cover, and the spherical panel shields one end of the material guiding groove.

[0009] For the integrated device for preventing blockage of gas and slag discharge as described above: A plurality of blocking rods are fixed between two adjacent inclined plates to form a filtering member.

[0010] For the integrated device for preventing blockage of gas and slag discharge as described above: A material guiding plate is fixed on two of the inclined plates.

[0011] The integrated device for preventing blockage of gas and slag discharge as described above: The guide plate is inclined outward along the radial direction of the furnace body.

[0012] The integrated device for preventing blockage of gas and slag discharge as described above: The integrated device for preventing blockage of gas and slag discharge further includes spiral guide vanes formed at the inner end of the furnace body, and the spiral guide vanes are used to convey the ash slag to the position of the guide trough when the furnace body rotates.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: A screw is arranged inside the screw discharge pipe for conveying the ash slag entering the screw discharge pipe outward. The position of the screw discharge pipe is fixed, so that the position of the guide trough is fixed. During the rotation of the furnace body, the ash slag is conveyed into the guide trough through the action of the spiral guide vanes. Due to the limitation of the filtering port area of the through groove, the ash slag meeting the conveying requirements enters the screw discharge pipe, thus eliminating to a certain extent the problem that too much ash slag remaining in the screw discharge pipe affects the exhaust. Moreover, if there is a blockage in the screw discharge pipe during the production process of the equipment, the blockage can be pushed into the furnace body by the reverse push of the screw to keep the screw discharge pipe unobstructed.

Detailed Description of the Invention

[0019] The following will describe in detail various exemplary embodiments, features and aspects of the present application with reference to the drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0020] The special term "exemplary" here means "serving as an example, embodiment or illustration". Any embodiment described as "exemplary" here does not necessarily have to be construed as superior to or better than other embodiments.

[0021] In addition, for better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art are not described in detail to highlight the gist of the present application.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, an integrated device for preventing blockage of gas and slag discharge is arranged inside the furnace body 1 and at the inner end of the furnace body 1. The integrated device for preventing blockage of gas and slag discharge communicates with the inside of the furnace body 1 and the screw conveyor discharge pipe 3 provided on the furnace body 1. The screw conveyor discharge pipe 3 penetrates through the gas and slag discharge port 2 formed on the furnace body 1 and has upper and lower openings to form a tee. The upper opening is for discharging gas, and the lower opening is for discharging slag. The integrated device for preventing blockage of gas and slag discharge includes:

[0023] An annular end cover 4 fixed on the furnace body 1 and a plurality of inclined plates 5 fixed circumferentially along the annular end cover 4. A material guiding groove 8 is formed between two adjacent inclined plates 5 in two groups, and the material guiding groove 8 communicates with the screw conveyor discharge pipe 3.

[0024] The integrated device for preventing blockage of gas and slag discharge further includes a spiral material guiding piece 11 formed at the inner end of the furnace body 1. The spiral material guiding piece 11 is used to convey ash slag to the position of the material guiding groove 8 when the furnace body 1 rotates. When the furnace body 1 rotates in the slag discharge direction, when the furnace body 1 is undergoing pyrolysis, the rotation direction of the furnace body 1 is opposite, so as to cooperate with the function of the spiral material guiding piece 1 to prevent ash slag or incompletely pyrolyzed raw materials from entering the material guiding groove 8.

[0025] In this embodiment, a screw is arranged inside the screw conveyor discharge pipe 3 for conveying the ash slag entering the screw conveyor discharge pipe 3 outwards. The position of the screw conveyor discharge pipe 3 is fixed, so that the position of the material guiding groove 8 is fixed. During the rotation of the furnace body 1, the ash slag is conveyed to the material guiding groove 8 through the action of the spiral material guiding piece 11. Due to the limitation of the passing area of the through groove 9, the ash slag meeting the conveying requirements enters the screw conveyor discharge pipe 3, thereby eliminating to a certain extent the problem that too much ash slag remaining in the screw conveyor discharge pipe 3 affects gas discharge. Moreover, if there is a blockage in the screw conveyor discharge pipe during the production process of the equipment, the blockage can be pushed into the furnace body by the reverse push of the screw to keep the screw conveyor discharge pipe unobstructed.

[0026] Further, a spherical panel 7 is fixed on the side of the inclined plate 5 away from the annular end cover 4, and the spherical panel 7 shields one end of the material guiding groove 8.

[0027] Among them, it should be noted that an annular member is formed between the annular end cover 4 and the spherical panel 7, the inclined plate 5 is fixed on the annular member, a through groove 9 is formed on the annular member located in the material guiding groove 8, and the ash slag entering the material guiding groove 8 enters the auger discharge pipe 3 through the through groove 9.

[0028] By providing the spherical panel 7 and the annular end cover 4, the material guiding groove 8 can be formed into a concave groove body, which is convenient for the ash slag to enter the auger discharge pipe 3.

[0029] To eliminate the blockage of the through groove 9 by larger ash slag, please refer to Figure 4 , a plurality of blocking rods 10 are fixed between two adjacent inclined plates 5 to form a filter member.

[0030] Furthermore, two of the inclined plates 5 are fixed with a material guiding plate 6. Preferably, the material guiding plate 6 is inclined outward along the radial direction of the furnace body 1 for guiding the ash slag conveyed by the spiral material guiding piece 11 into the material guiding groove 8.

[0031] 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 without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. 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 claimed claim.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
