Description

Technical Field

[0001] The present invention relates to the technical field of cracking furnaces, and more specifically, to an experimental device for an electrically heated cracking furnace. Background Art

[0002] In the technical field of cracking furnaces, many problems have emerged in the actual application of traditional experimental devices. In common cracking furnaces, due to insufficient agitation of the materials, the materials are unevenly heated, resulting in poor cracking effects. For example, some devices lack an effective material turning structure, and the materials are relatively stationary in the furnace, and the cracking reaction only occurs by heat conduction. This causes the materials close to the heat source to be over-cracked, while the materials far from the heat source are insufficiently cracked, and efficient and uniform cracking cannot be achieved.

[0003] At the same time, there are also certain defects in the structural design of existing cracking furnaces. The connection method between the inner cylinder and the outer shell of some cracking furnaces is not flexible enough, which limits the rotation effect of the inner cylinder, and thus affects the agitation and cracking process of the materials. In addition, the sealing performance of the equipment is poor, resulting in heat loss, which not only increases energy consumption but also may affect the stability and accuracy of the cracking reaction. These problems seriously restrict the application of cracking furnaces in experiments and actual production, and there is an urgent need for a new experimental device for an electrically heated cracking furnace to solve these problems. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an experimental device for an electrically heated cracking furnace, which has the advantage of good cracking effect.

[0005] To achieve the above object, the present invention provides the following technical solution: An experimental device for an electrically heated cracking furnace, including a cracking furnace outer shell, and a cracking furnace inner cylinder is rotatably connected inside the cracking furnace outer shell through two sets of annularly distributed guide wheels, and the central axes of the cracking furnace inner cylinder and the cracking furnace outer shell coincide;

[0006] A turning inclined plate is fixed on the inner wall of the cracking furnace inner cylinder along its central axis direction, and the included angle between the tangent at the connection of the turning inclined plate and the cracking furnace inner cylinder is an acute angle, and the turning inclined plate is biased towards the side of the rotation direction of the cracking furnace inner cylinder;

[0007] The cracking furnace inner cylinder is driven by a driving motor;

[0008] A number of arc-shaped distributed electric heating wires are fixed on the inner wall of the cracking furnace outer shell and below the cracking furnace inner cylinder.

[0009] As a preferred technical solution of the present invention, a support bracket for support is fixedly installed at the bottom of the cracking furnace outer shell, and universal wheels for movement are provided at the bottom of the support bracket.

[0010] As a preferred technical solution of the present invention, an "I"-shaped rotating shaft penetrates and rotates through the sealing end of the cracking furnace outer shell. One end of the "I"-shaped rotating shaft located inside the cracking furnace outer shell is fixed on the inner cylinder of the cracking furnace. The output end of the driving motor is fixedly connected to one end of the "I"-shaped rotating shaft located outside the cracking furnace outer shell, and the driving motor is fixed on the cracking furnace outer shell through a motor support.

[0011] As a preferred technical solution of the present invention, a cylinder cover is installed at the open end of the inner cylinder of the cracking furnace, and the cylinder cover is detachably installed on the inner cylinder of the cracking furnace.

[0012] As a preferred technical solution of the present invention, a sealing ring is fixed on the inner wall of the cracking furnace outer shell, and the inner wall of the sealing ring is in sliding fit with the circumferential side surface of the inner cylinder of the cracking furnace.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When the inner cylinder of the cracking furnace rotates in the present invention, the turning inclined plate can drive the material to rotate upward for a certain distance. When the turning inclined plate continues to rotate upward, the material inside the turning inclined plate slides down due to the action of gravity, thereby realizing the turnover of the material, and thus making the cracking effect of the material better.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Such as Figures 1 to 3As shown in the figure, the present invention provides an experimental device for an electric heating cracking furnace, including a cracking furnace outer casing 1. Inside the cracking furnace outer casing 1, a cracking furnace inner cylinder 4 is rotatably connected through two groups of guide wheels 3 distributed in a ring shape, and the central axis of the cracking furnace inner cylinder 4 coincides with that of the cracking furnace outer casing 1;

[0021] On the inner wall of the cracking furnace inner cylinder 4, a turning inclined plate 5 is fixed along its central axis direction. The included angle between the tangent line at the connection of the turning inclined plate 5 and the cracking furnace inner cylinder 4 is an acute angle, and the turning inclined plate 5 biases towards the side of the rotation direction of the cracking furnace inner cylinder 4;

[0022] The cracking furnace inner cylinder 4 is driven by a driving motor 6;

[0023] On the inner wall of the cracking furnace outer casing 1 and below the cracking furnace inner cylinder 4, a number of electric heating wires 9 are fixed in an arc distribution.

[0024] At the bottom of the cracking furnace outer casing 1, a support bracket 2 for support is fixedly installed, and universal wheels for movement are arranged at the bottom of the support bracket 2;

[0025] A "worker"-shaped rotating shaft 7 penetrates and rotates through the sealing end of the cracking furnace outer casing 1. One end of the "worker"-shaped rotating shaft 7 located inside the cracking furnace outer casing 1 is fixed on the cracking furnace inner cylinder 4, the output end of the driving motor 6 is fixedly connected to one end of the "worker"-shaped rotating shaft 7 located outside the cracking furnace outer casing 1, and the driving motor 6 is fixed on the cracking furnace outer casing 1 through a motor support 8;

[0026] At the open end of the cracking furnace inner cylinder 4, a cylinder cover 10 is installed, and the cylinder cover 10 is detachably installed on the cracking furnace inner cylinder 4;

[0027] On the inner wall of the cracking furnace outer casing 1, a sealing ring 11 is fixed, and the inner wall of the sealing ring 11 is in sliding fit with the circumferential side surface of the cracking furnace inner cylinder 4.

[0028] Working principle and usage process of the present invention: When the electric heating cracking furnace test device of the present invention is to be used, first, the staff opens the cylinder cover 10, then places the material to be cracked inside the inner cylinder 4 of the cracking furnace, and then locks the cylinder cover 10. Start the electric heating wire 9 to heat the inside of the inner cylinder 4 of the cracking furnace through the electric heating wire 9. At the same time, start the control switch of the driving motor 6, and drive the inner cylinder 4 of the cracking furnace to rotate through the driving motor 6. Since the turning inclined plate 5 is fixed along the central axis direction on the inner wall of the inner cylinder 4 of the cracking furnace, the included angle between the tangent at the connection of the turning inclined plate 5 and the inner cylinder 4 of the cracking furnace is an acute angle, and the turning inclined plate 5 biases towards the side of the rotation direction of the inner cylinder 4 of the cracking furnace. Therefore, when the inner cylinder 4 of the cracking furnace rotates, the turning inclined plate 5 can drive the material to rotate upward for a certain distance. When the turning inclined plate 5 continues to rotate upward, the material inside the turning inclined plate 5 slides down due to the action of gravity, thereby realizing the turning of the material, and thus making the cracking effect of the material better.
