Description

Technical Field

[0001] This utility model relates to the field of coal-fired catalyst preparation technology, specifically to a coal-fired catalyst reaction device. Background Technology

[0002] Coal combustion has several drawbacks, such as incomplete combustion producing harmful gases like carbon monoxide, prolonged combustion time, and reduced combustion efficiency. To accelerate combustion and improve efficiency, related technologies involve adding catalysts to the coal, using chemical catalysis to enhance combustion. For example:

[0003] One technology provides an aqueous dispersion comprising magnesium sulfate, nickel salt, rare earth elements, and emulsifiers as a coal-saving agent; another technology provides a coal-saving agent comprising solid and liquid components, wherein the solid component is a mixture of sodium chloride, ammonium persulfate, cerium nitrate, polyoxyethylene ether, potassium chlorate, and calcium chloride dispersed in alkaline ethanol and then re-dried; and the liquid component is an aqueous dispersion of sodium lignosulfonate, graphene, and hydroxypropyl methylcellulose.

[0004] The preparation of coal-fired catalysts requires the input of various materials into a reaction apparatus. However, in existing reaction apparatuses, materials tend to accumulate in one place during feeding. Although a stirring mechanism is installed to agitate the materials, some materials still cannot be mixed evenly, affecting the reaction rate and efficiency. Furthermore, the stirring structure of existing reaction apparatuses is a fixed unit. When the stirring structure is damaged and needs to be disassembled and replaced, it cannot be done quickly, thus affecting the progress of subsequent work. Summary of the Invention

[0005] To address the problems of existing technologies, this utility model provides a coal-fired catalyst reaction device, including a reaction tank. The top of the reaction tank is provided with a feed inlet, and the feed inlet is connected to a dispersion mechanism inside the reaction tank to disperse the material. The dispersion mechanism includes a vertical section and a dispersion section. The upper end of the vertical section is connected to the feed inlet, and the lower end of the vertical section is connected to the upper end of the dispersion section. The dispersion section is provided with a plurality of dispersion holes that communicate with the inside of the reaction tank.

[0006] The reaction vessel is equipped with a stirring shaft for stirring materials, and the stirring shaft is mounted on the surface of the mounting shaft. The stirring shaft and the mounting shaft are disassembled and assembled by a disassembly mechanism. A stirring motor is installed at the top of the reaction vessel, and the upper end of the mounting shaft passes through the reaction vessel and is connected to the power output shaft of the stirring motor.

[0007] A further option is that the inner diameter of the dispersed segment gradually increases in the direction away from the vertical segment.

[0008] A further embodiment is that the dispersion holes include a plurality of first dispersion holes and a plurality of second dispersion holes, wherein each of the first dispersion holes is equidistantly spaced at the bottom of the dispersion section; and the plurality of second dispersion holes are distributed along the periphery of the dispersion section.

[0009] A further embodiment is that the disassembly mechanism includes a rotating block and a threaded block. The threaded block is installed on one side of the rotating block, the rotating block is located on one side of the annular block, the annular block is installed on the surface of the mounting shaft, the bottom of the stirring shaft is equipped with a mounting block, the top of the mounting block is equipped with an insert block, the bottom of the mounting shaft has a slot adapted to the insert block, and the right end of the threaded block passes through the annular block and the mounting shaft from left to right and extends into the interior of the mounting shaft and is threadedly connected to the inner wall of the mounting shaft.

[0010] A further embodiment is that the stirring shaft is symmetrically provided with horizontal blades and arc-shaped blades located below the horizontal blades. Both the horizontal blades and the arc-shaped blades are spiral-shaped, and the edges of both the horizontal blades and the arc-shaped blades gradually thicken towards the middle, forming a double-edged sword shape.

[0011] A further option is to provide several through holes on the horizontal blades and the arc-shaped blades.

[0012] Beneficial effects of this utility model

[0013] This invention connects a dispersion mechanism to the lower end of the feed inlet of the reaction vessel, allowing different materials entering the reaction vessel to be more dispersed inside the vessel, thereby increasing the contact area between different materials and accelerating the mixing of different materials.

[0014] This invention features a disassembly structure that allows the stirring shaft to be detachably mounted on the mounting shaft, facilitating the disassembly, inspection, and replacement of the stirring shaft. This avoids the problem of the stirring shaft and the reaction vessel being fixed as a single unit, which would hinder disassembly. Moreover, the disassembly and assembly process is simple and convenient. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-3 As shown, one embodiment of this utility model discloses a coal-fired catalyst reaction device, including a reaction tank 1. A feed inlet 2 is provided at the top of the reaction tank 1. The feed inlet 2 is located inside the reaction tank 1 and connected to a dispersion mechanism for dispersing materials. The dispersion mechanism includes a vertical section 30 and a dispersion section 31. The upper end of the vertical section 30 is connected to the feed inlet 2, and the lower end of the vertical section 30 is connected to the upper end of the dispersion section 31. The dispersion section 31 is provided with a plurality of dispersion holes communicating with the interior of the reaction tank 1. The inner diameter of the dispersion section 31 gradually increases in the direction away from the vertical section 30. The dispersion holes include a plurality of first dispersion holes 32 and a plurality of second dispersion holes 33. Each first dispersion hole 32 is equidistantly spaced at the bottom of the dispersion section 31; the plurality of second dispersion holes 33 are distributed along the peripheral wall of the dispersion section 31.

[0021] This embodiment, through the above-described configuration, allows multiple materials to be sequentially fed into the reaction vessel through the inlet. Different materials enter the vertical section and dispersion section of the dispersion mechanism sequentially through the inlet. As the inner diameter of the dispersion section increases from top to bottom, the materials gradually disperse during their descent through the dispersion section and enter the interior of the reaction vessel more dispersedly through several first dispersion holes at the bottom and several second dispersion holes on the side. This increases the contact area between the materials entering the reaction vessel later and those entering earlier, accelerating the mixing of different materials and reducing the stirring time of the stirring shaft.

[0022] The reaction vessel 1 is equipped with a stirring shaft 40 for stirring materials. The stirring shaft 40 is mounted on the surface of the mounting shaft 41. The stirring shaft 40 and the mounting shaft 41 are disassembled and reassembled by a disassembly mechanism. A stirring motor 42 is mounted on the top of the reaction vessel 1. The upper end of the mounting shaft 41 passes through the reaction vessel 1 and is connected to the power output shaft of the stirring motor 42. The disassembly mechanism includes a rotating block 50 and a threaded block 51. The threaded block 51 is mounted on one side of the rotating block 50. The rotating block 50 is located on one side of the annular block 52. The annular block 52 is mounted on the surface of the mounting shaft 41. A mounting block 53 is mounted on the bottom of the stirring shaft 40. An insert block 54 is mounted on the top of the mounting block 53. A slot 55 that matches the insert block 54 is opened at the bottom of the mounting shaft 41. The right end of the threaded block 51 passes through the annular block 52 and the mounting shaft 41 from left to right and extends into the interior of the mounting shaft 41 and is threadedly connected to the inner wall of the mounting shaft 41.

[0023] It should be noted that the stirring shaft in this embodiment can stir the mixed materials, further making the materials more uniform.

[0024] This embodiment, through the above-described configuration, enables the following steps when the stirring shaft needs to be disassembled and maintained: opening the top cover of the reaction vessel allows the mounting shaft and stirring shaft to be pulled out of the reaction vessel; then rotating the rotating block causes the threaded block to move to the right, causing the threaded block and mounting shaft to separate; then pulling the stirring shaft downwards causes the stirring shaft to separate the insert block and slot via the mounting block, allowing the stirring shaft to be removed from the mounting shaft.

[0025] Therefore, the stirring shaft in this embodiment can be quickly disassembled from the convenient stirring structure, which facilitates the disassembly, inspection and replacement of the stirring shaft. This avoids the problem of the stirring shaft and the reaction vessel being fixed as one unit, which would affect the disassembly. Moreover, the disassembly and assembly process is simple and convenient, which improves its practicality.

[0026] In this embodiment, a horizontal blade 400 and an arc-shaped blade 401 located below the horizontal blade 400 are symmetrically arranged on the stirring shaft 40. Both the horizontal blade 400 and the arc-shaped blade 401 are spiral-shaped, and the edges of both sides of the blades of the horizontal blade 400 and the arc-shaped blade 401 gradually thicken towards the middle, forming a double-edged sword shape.

[0027] This embodiment achieves the goal of reducing motion resistance by setting the blades to a fence-like spiral ribbon shape, which allows the blades to rotate at a certain angle to the direction of fluid movement, thus facilitating increased stirring speed and more thorough mixing of materials.

[0028] In this embodiment, the horizontal blade 400 and the arc-shaped blade 401 are provided with a plurality of through holes 402.

[0029] This embodiment achieves the goal of increasing the liquid's movement space and power by setting a through-hole structure on the impeller, thereby accelerating the liquid's flow and diffusion, and further making the material mix more thoroughly.

[0030] Finally, it should be noted that the above description only details specific embodiments of this utility model. However, this utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made to this utility model by those skilled in the art are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model are covered within the scope of this utility model.
