Anti-gumming pyrolyzing furnace rotating inner cylinder

Abstract

The utility model relates to the technical field of pyrolyzing furnaces, in particular to an anti-gumming rotary inner barrel of a pyrolyzing furnace. The anti-gumming pyrolyzing furnace rotating inner barrel comprises an inner barrel body and a plurality of solid compression counterweight steel balls arranged in the inner barrel body in a rolling mode, and each solid compression counterweight steel ball is provided with a limiting connecting piece used for limiting the rolling direction of the solid compression counterweight steel ball. According to the anti-gelatinizing rotary inner barrel of the pyrolyzing furnace, the solid compression counterweight steel balls are large in weight and density and limited by the limiting connecting pieces, so that the solid compression counterweight steel balls sink to the bottom of the inner barrel body when the inner barrel body rotates, and after materials attached to the inner wall of the inner barrel body rotate to a low position, the solid compression counterweight steel balls are separated from the inner barrel body; therefore, the hidden danger that the materials are adhered to the inner barrel body and are glued and solidified is eliminated.

Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis furnaces, in particular to a rotating inner cylinder of an anti-gelling pyrolysis furnace. Background Art

[0002] A pyrolysis furnace is a device used to thermally decompose materials at high temperatures to obtain fuel or chemical raw materials. During the pyrolysis process in a high-temperature pyrolysis furnace, the reactor is in a high-temperature reducing atmosphere, which can effectively reduce the formation of PCDD / F and NOx, and gasify tar into small molecular compounds. Most of the gas produced by the pyrolysis in a high-temperature pyrolysis furnace is combustible gas, which can be widely used in industrial furnace heating, steam power generation and internal combustion engine power generation, and can also be used as a raw material to produce synthetic natural gas. At present, when some horizontal rotary pyrolysis furnaces are pyrolyzing materials, the pyrolyzed materials are easy to gel and solidify in the rotating inner cylinder, which is difficult to remove after a long time. At the same time, as the amount of gelled and solidified materials increases, the pyrolysis effect of the pyrolysis furnace is greatly reduced.

[0003] Therefore, it is necessary to provide a new rotating inner cylinder of an anti-gelling pyrolysis furnace to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a rotating inner cylinder of an anti-gelling pyrolysis furnace.

[0005] The utility model provides a rotary inner cylinder of an anti-gelling pyrolysis furnace, comprising:

[0006] The inner cylinder, and

[0007] A plurality of solid compression weighted steel balls rollingly arranged in the inner cylinder, each of which is provided with a limit connecting piece for limiting the rolling direction of the solid compression weighted steel balls;

[0008] The limiting connecting piece includes a sliding ball, which is arranged in an annular spherical cavity opened in the inner cylinder and is slidably connected to the annular spherical cavity, and a connecting rod 1 is fixedly installed on the sliding ball, and the connecting rod 1 passes through the annular connecting cavity opened in the inner cylinder above the annular spherical cavity and extends into the inner cylinder, and a sleeve ring is fixedly installed on the connecting end of the connecting rod 1, and the sleeve ring is sleeved in an annular groove opened in a solid compression counterweight steel ball and is rotatably connected to the annular groove, and the solid compression counterweight steel ball is in rolling contact with the inner bottom wall of the inner cylinder.

[0009] Preferably, the inner cylinder is provided with a plurality of equally spaced annular spherical cavities, and the annular spherical cavities are coaxially arranged with the inner cylinder, and each of the annular spherical cavities is connected with the inner cavity of the inner cylinder through an annular connecting cavity provided in the inner cylinder.

[0010] Preferably, the annular groove formed on the solid compression weighted steel ball is arranged parallel to the axis of the annular spherical cavity formed on the inner cylinder.

[0011] Preferably, a curved shovel is fixedly mounted on the connecting rod, and the shovel head of the curved shovel is arranged opposite to the rotation direction of the inner cylinder.

[0012] Preferably, the front shovel surface of the curved shovel is concave, and the rear shovel surface of the curved shovel is convex.

[0013] Preferably, a second connecting rod is fixedly mounted on the solid compression weight steel ball, and the second connecting rod is arranged parallel to the axis of the inner cylinder, both ends of the second connecting rod are sleeved with rotatably connected side rolling steel balls, and the side rolling steel balls are in contact with the inner cylinder wall of the inner cylinder.

[0014] Compared with the related art, the rotating inner cylinder of the anti-gum pyrolysis furnace provided by the utility model has the following beneficial effects:

[0015] 1. In the utility model, since the solid compression weight steel ball is heavy, dense and limited by the limit connecting piece, the solid compression weight steel ball sinks to the bottom of the inner cylinder when the inner cylinder rotates. Therefore, after the material attached to the inner wall of the inner cylinder rotates to a low position, it will be pushed by the solid compression weight steel ball, thereby eliminating the hidden danger of the material being glued and solidified due to adhesion to the inner cylinder;

[0016] 2. In the utility model, when the inner cylinder rotates, the sliding ball rolls along the annular spherical cavity, thereby effectively limiting the direction of the self-rolling of the solid compression counterweight steel ball along the inner wall of the inner cylinder, avoiding collision between the solid compression counterweight steel balls due to random rolling of the solid compression counterweight steel balls. Since the sleeve ring is sleeved in the annular groove opened by the solid compression counterweight steel ball, it does not affect the rolling of the solid compression counterweight steel ball.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 3 The embodiment of the utility model provides a rotating inner cylinder of an anti-gelling pyrolysis furnace, and the rotating inner cylinder of the anti-gelling pyrolysis furnace includes: an inner cylinder body 1, a solid compression weighted steel ball 2 and a limiting connector 3.

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , the inner cylinder 1 is provided with a plurality of equally spaced annular spherical cavities 1a, and the annular spherical cavities 1a are coaxially arranged with the inner cylinder 1, and each of the annular spherical cavities 1a is connected with the inner cavity of the inner cylinder 1 through the annular connecting cavity 1b provided with the inner cylinder 1, and the inner cylinder 1 is provided with a plurality of rolling solid compression weighted steel balls 2, and the solid compression weighted steel balls 2 correspond to each other one by one, and each of the solid compression weighted steel balls 2 is provided with a limit connecting piece 3 for limiting the rolling direction of the solid compression weighted steel balls 2;

[0025] The limiting connecting member 3 includes a sliding ball 31, which is arranged in the annular spherical cavity 1a opened in the inner cylinder 1 and is slidably connected to the annular spherical cavity 1a, and a connecting rod 32 is fixedly installed on the sliding ball 31, and the connecting rod 32 passes through the annular connecting cavity 1b opened in the inner cylinder 1 above the annular spherical cavity 1a and extends into the inner cylinder 1, and a sleeve ring 33 is fixedly installed on the connecting end of the connecting rod 32, and the sleeve ring 33 is sleeved in the annular groove 2a opened in the solid compression counterweight steel ball 2 and is rotatably connected to the annular groove 2a, and the solid compression counterweight steel ball 2 is in rolling contact with the inner bottom wall of the inner cylinder 1.

[0026] It should be noted that: when the inner cylinder 1 in the pyrolysis furnace pyrolyzes the material, due to the large weight and density of the solid compression weighted steel balls 2 and the limitation of the limit connector 3, the solid compression weighted steel balls 2 sink to the bottom of the inner cylinder 1 when the inner cylinder 1 rotates, so the material attached to the inner wall of the inner cylinder 1 will be pushed by the solid compression weighted steel balls 2 after rotating to a low position, thereby eliminating the hidden danger of the material being glued and solidified due to adhesion to the inner cylinder 1;

[0027] When the inner cylinder 1 rotates, the sliding ball 31 rolls along the annular spherical cavity 1a, thereby effectively limiting the self-rolling direction of the solid compression counterweight steel ball 2 along the inner wall of the inner cylinder 1, and avoiding collisions between the solid compression counterweight steel balls 2 due to random rolling of the solid compression counterweight steel balls 2. Since the sleeve ring 33 is sleeved in the annular groove 2a opened in the solid compression counterweight steel ball 2, it does not affect the rolling of the solid compression counterweight steel ball 2.

[0028] The annular groove 2a of the solid compression weighted steel ball 2 is arranged parallel to the axis of the annular spherical cavity 1a of the inner cylinder 1, so that when the inner cylinder 1 rotates, the solid compression weighted steel ball 2 is located at the lower point of the inner cylinder 1 and rolls on its own.

[0029] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 A curved shovel 4 is fixedly mounted on the connecting rod 32, and the shovel head of the curved shovel 4 is arranged opposite to the rotation direction of the inner cylinder 1, and the front shovel surface of the curved shovel 4 is concave, and the rear shovel surface of the curved shovel 4 is convex.

[0030] It should be noted that the curved shovel 4 can continuously turn the material falling into the annular spherical cavity 1a outward into the inner cylinder 1, thereby preventing the material falling into the annular spherical cavity 1a from solidifying in the annular spherical cavity 1a during pyrolysis.

[0031] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 A connecting rod 2 5 is fixedly installed on the solid compression counterweight steel ball 2, and the connecting rod 2 5 is arranged parallel to the axis of the inner cylinder 1. Both ends of the connecting rod 2 5 are sleeved with side rolling steel balls 6 that are rotatably connected, and the side rolling steel balls 6 are in contact with the inner cylinder wall of the inner cylinder 1. The side rolling steel balls 6 arranged on both sides of the solid compression counterweight steel ball 2 greatly improve the capacity for pushing the material in the inner cylinder 1.

[0032] The working principle of the rotating inner cylinder of the anti-gelling pyrolysis furnace provided by the utility model is as follows:

[0033] When the inner cylinder 1 in the pyrolysis furnace pyrolyzes the material, due to the large weight and density of the solid compression weight steel ball 2 and the limitation of the limit connector 3, the solid compression weight steel ball 2 sinks to the bottom of the inner cylinder 1 when the inner cylinder 1 rotates. Therefore, after the material attached to the inner wall of the inner cylinder 1 rotates to a low position, it will be pushed by the solid compression weight steel ball 2, thereby eliminating the hidden danger of the material sticking to the inner cylinder 1 and solidifying. When the inner cylinder 1 rotates, the sliding ball 31 rolls along the annular spherical cavity 1a, thereby effectively limiting the direction of the solid compression weight steel ball 2 rolling along the inner wall of the inner cylinder 1, avoiding the solid compression weight steel ball 2 from colliding with each other due to the random rolling of the solid compression weight steel ball 2. Since the sleeve ring 33 is sleeved in the annular groove 2a opened by the solid compression weight steel ball 2, it does not affect the rolling of the solid compression weight steel ball 2.

[0034] The curved shovel 4 can continuously turn the material falling into the annular spherical cavity 1a outward into the inner cylinder 1, thereby preventing the material falling into the annular spherical cavity 1a from solidifying in the annular spherical cavity 1a during pyrolysis.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
