Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and specifically relates to a batch reactor for the production of alkane dehydrogenation catalyst. Background Technology

[0002] Alkane dehydrogenation is the process of converting saturated alkanes into unsaturated olefins. It is widely used in the petrochemical industry, especially in the production of important chemical raw materials such as propylene and butene. In order to improve reaction efficiency and reduce energy consumption, a high-efficiency catalyst is usually required to promote this conversion process. The production of alkane dehydrogenation catalysts requires the use of a batch reactor to achieve material mixing and reaction.

[0003] Existing batch reactors for alkane dehydrogenation catalyst production gradually add raw materials to the reactor through a top opening or side pipe. An internal stirring module effectively promotes uniform dispersion of liquid or solid particles, preventing excessively high local concentrations that could lead to side reactions. After the reaction, the product is discharged through a bottom discharge valve. However, before each use, the reactor and its accessories must be thoroughly cleaned to remove residual substances and avoid cross-contamination. This requires workers to repeatedly rinse the inside of the reactor with clean water or other solvents using a hose after each use until no obvious impurities are present, and then allow it to dry. This process, ensuring complete cleaning of the reactor's interior, takes considerable time and places a significant workload on the staff. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a batch reactor for the production of alkane dehydrogenation catalysts. After the reaction materials are mixed in the reactor, the interior of the reactor can be quickly cleaned by the combination of a nozzle and a scraper plate set at the top of the reactor, which can effectively reduce the degree of human intervention and facilitate use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a batch reactor for the production of alkane dehydrogenation catalyst, comprising a reactor body, multiple nozzles at the upper end of the reactor body, a drive box at the top of the reactor body, a rotating ring at the bottom of the drive box, a splined cylinder slidably arranged in the middle of the rotating ring, a stirring rack at the bottom of the splined cylinder, symmetrically distributed scraper plates on the outer side of the stirring rack, multiple support shafts on the outer arc surface of the splined cylinder, drive wheels rotatably arranged on the outer arc surface of each support shaft, a drive rail at the bottom of the drive box, and drive wheels that are fitted with the drive rail; multiple clamps at the upper end of the reactor body, a feed pipe between each clamp and the reactor body, a discharge pipe at the bottom of the reactor body, a solenoid valve one at the upper end of each feed pipe, and a solenoid valve two at the lower end of each discharge pipe; and uniformly distributed auxiliary mixing plates in the middle of the stirring rack.

[0006] As a further improvement of this utility model, the upper surface of the rotating ring is provided with evenly distributed sliding columns, which are slidably connected to adjacent support shafts respectively. A return spring is provided between the support shaft and the rotating ring, and the return spring is sleeved on the outside of the sliding column. A spline is rotatably provided at the top of the inside of the drive box, and the spline is installed in conjunction with the spline cylinder. A motor is provided at the top of the reactor body, and the output shaft of the motor is fixed to the spline by a coupling.

[0007] As a further improvement of this utility model, a control box is provided on the outside of the reactor body, and solenoid valve one, solenoid valve two and motor are all electrically connected to the control box.

[0008] As a further improvement of this utility model, the lower end of the reactor body is provided with evenly distributed support legs, and the bottom end of each support leg is provided with a rubber anti-slip pad by adhesive.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the motor is controlled by the control box, which causes the output shaft of the motor to rotate the spline connected to it. This, in turn, allows the material at the bottom of the reactor to be quickly and evenly mixed through the stirring rack, the scraper on the stirring rack, and the auxiliary mixing plate, thus aiding in the reaction of the material.

[0011] Secondly, during the rotation of the splined cylinder, the outer support shaft is driven to rotate, which in turn drives the mixing frame and the scraper and auxiliary mixing plate on the mixing frame to rotate up and down, which can effectively assist in the mixing and homogenization of the materials.

[0012] Third, connect the nozzle to an external water pipe or other solvent delivery pipe so that the nozzle sprays clean water or other solvents into the inside of the reactor. Then, the control box controls the motor to make the stirring rack move up and down as it drives the scraper to rotate, which can quickly clean the inside of the reactor.

[0013] Fourth, the rubber anti-slip mat allows the support legs to make flexible contact with the ground while increasing the friction between them, which can effectively prevent the reactor body from moving easily. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 4 As shown, the reactor includes a reactor body 101. Multiple nozzles 201 are installed at the upper end of the reactor body 101. A drive box 202 is installed at the top inside the reactor body 101. A rotating ring 203 is rotatably installed at the bottom inside the drive box 202. A splined cylinder 204 is slidably installed in the middle of the rotating ring 203. A stirring rack 205 is installed at the bottom of the splined cylinder 204. Symmetrically distributed scraper plates 207 are installed on the outer side of the stirring rack 205. Multiple support shafts 208 are installed on the outer arc surface of the splined cylinder 204. Drive wheels 209 are rotatably installed on the outer arc surface of each support shaft 208. A drive rail 210 is installed at the bottom inside the drive box 202, and the drive wheels 209 are all fitted and installed with the drive rail 210. Evenly distributed auxiliary mixing plates 206 are installed in the middle of the stirring rack 205.

[0022] like Figure 2 , 4 As shown, the upper end of the reactor body 101 is provided with multiple clamps 103, and each clamp 103 is connected to the reactor body 101 with a feed pipe 104. The bottom end of the reactor body 101 is provided with a discharge pipe. The upper end of each feed pipe 104 is provided with a solenoid valve 105, and the lower end of each discharge pipe is provided with a solenoid valve 106.

[0023] like Figure 3 , 4As shown, a spline 211 is rotatably provided at the top of the drive box 202. The spline 211 is installed in conjunction with the spline cylinder 204. A motor 212 is provided at the top of the reactor body 101. The output shaft of the motor 212 is fixed to the spline 211 by a coupling. The upper surface of the rotating ring 203 is provided with evenly distributed sliding columns 213. The sliding columns 213 are slidably connected to the adjacent support shafts 208. A return spring 214 is provided between the support shafts 208 and the rotating ring 203. The return springs 214 are all sleeved on the outside of the sliding columns 213.

[0024] like Figure 1 , 2 As shown, a control box 301 is installed on the outside of the reactor body 101. Solenoid valve 105, solenoid valve 206 and motor 212 are all electrically connected to the control box 301.

[0025] In use, the feed pipe 104 is connected to the external feeding pipe, and the control box 301 regulates the solenoid valve 105 to run for different durations, so that a certain proportion of material enters the interior of the reactor body 101 from the feed pipe 104.

[0026] The control box 301 regulates the operation of motor 212, causing the output shaft of motor 212 to drive the spline 211 connected to it to rotate. This, in turn, causes spline 211 to drive the stirring frame 205, the scraper 207 on the stirring frame 205, and the auxiliary mixing plate 206 via spline cylinder 204 to rotate. This, in turn, allows the stirring frame 205, the scraper 207 on the stirring frame 205, and the auxiliary mixing plate 206 to rapidly and uniformly mix the material at the bottom of the reactor body 101, aiding in the material's reaction. During the rotation of spline cylinder 204, spline cylinder 204 drives the outer support shaft 208 to rotate, which in turn causes the spline cylinder 204 to rotate via the support shaft... 208 drives the drive wheel 209 to move on the drive rail 210. The drive wheel 209 and the drive rail 210 work together to drive the splined cylinder 204 to rotate up and down during rotation. This, in turn, drives the mixing frame 205 and the scraper 207 and auxiliary mixing plate 206 on the mixing frame 205 to rotate up and down during rotation. During the rotation of the splined cylinder 204, the reset tension spring 214 set between the support shaft 208 and the rotating ring 203 assists the up and down reciprocating movement of the splined cylinder 204, which can effectively assist in the mixing and homogenization of the material. The control box 301 controls the operation of the solenoid valve 106, so that the material after the mixing reaction is completed is quickly discharged from the discharge pipe.

[0027] When it is necessary to clean the inside of the reactor body 101, the nozzle 201 is connected to an external water pipe or other solvent delivery pipe, so that the nozzle 201 sprays clean water or other solvents into the inside of the reactor body 101. Then, the control box 301 controls the motor 212 to run, so that the stirring rack 205 drives the scraper 207 to move up and down repeatedly during rotation, which can quickly clean the inside of the reactor body 101.

[0028] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, the lower end of the reactor body 101 is provided with evenly distributed support legs 102, and the bottom of each support leg 102 is provided with a rubber anti-slip pad. During use, the rubber anti-slip pads at the bottom of the support legs 102 allow the support legs 102 to make flexible contact with the ground while increasing the friction between the support legs and the ground, which can effectively prevent the position of the reactor body 101 from easily moving.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
