Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, and more specifically, to a stirring device for catalyst production. Background Technology

[0002] In the field of catalyst production, stirring devices are key equipment to ensure uniform mixing of materials and full reaction. As a common stirring container, stirred tanks are widely used in various catalyst production processes. However, in actual production, traditional stirred tanks have some significant problems.

[0003] Because the materials used in catalyst production often have certain density differences and viscosity characteristics, stratification and sedimentation are prone to occur during the stirring process. Heavy materials gradually settle at the bottom of the mixing tank, resulting in uneven material concentration distribution within the tank. Furthermore, after stirring, the discharge method of traditional mixing tanks usually relies on gravity flow, which is relatively slow. Therefore, we have made improvements and proposed a stirring device for catalyst production. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] For an example, please refer to... Figures 1-4A stirring device for catalyst production includes a stirring tank 1 with a stirring structure. A discharge pipe is located at the bottom of one side of the stirring tank 1. A connecting pipe 202 is connected to the inner wall of the discharge pipe via a sealed bearing. A conveying pipe 201 is fixedly connected to the end of the connecting pipe 202 away from the stirring tank 1. The conveying pipe 201 is connected to a discharge pipe 203 located above the stirring tank 1. A second motor 204 is installed at the bottom of the conveying pipe 201. A first gear 205 is installed inside the conveying pipe 201 and is connected to the output shaft of the second motor 204. During the stirring process, the connecting pipe... Pipe 202, conveying pipe 201, discharge pipe 203, second motor 204, and first gear 205 can extract the material in the mixing tank 1 and add it from the top of the mixing tank 1, so that the material in the mixing tank 1 circulates, reducing the deposition of material at the bottom of the mixing tank 1 and making the material more uniformly mixed; after the mixing is completed, the connecting pipe 202, conveying pipe 201, discharge pipe 203, second motor 204, and first gear 205 work together to discharge the material. Compared with the traditional gravity natural flow, this application can quickly discharge the material from the mixing tank 1, shortening the discharge time.

[0028] Furthermore, there is a driving component between the connecting pipe 202 and the mixing tank 1. The driving component is used to drive the connecting pipe 202 and the conveying pipe 201 to rotate, so as to adjust the position of the conveying pipe 201, so that the conveying pipe 201 can stand upright during mixing and be horizontal during discharge.

[0029] Furthermore, the driving component includes a first gear 205 fixedly sleeved on the outer surface of the connecting pipe 202, the first gear 205 meshing with a second gear 206, and the second gear 206 connected to a third motor 207, the third motor 207 being able to drive the connecting pipe 202 and the conveying pipe 201 to rotate through the second gear 206 and the first gear 205.

[0030] Furthermore, a second support plate 208 is installed at the bottom of the mixing tank 1, and a third motor 207 is installed on the second support plate 208. The second support plate 208 and the mixing tank 1 cooperate to support the third motor 207.

[0031] Furthermore, a fixing structure 3 is provided between the outer surface of the mixing tank 1 and the conveying pipe 201. The fixing structure 3 is used to fix the position of the conveying pipe 201 so that the conveying pipe 201 maintains a stable position when it is erected.

[0032] Furthermore, the fixing structure 3 includes a second fixing seat 306 fixedly installed on the mixing tank 1, and a limiting rod 305 fixedly installed on the side of the second fixing seat 306 away from the mixing tank 1; a first fixing seat 301 is fixedly sleeved on the outer surface of the conveying pipe 201, and a connecting shaft 302 is fixedly installed on the side of the first fixing seat 301 away from the mixing tank 1. A clamping plate 303 is rotatably connected to the outer surface of the connecting shaft 302 through a bearing. A clamping groove 304 is opened at the bottom of the clamping plate 303, and the clamping groove 304 is inserted into the outer surface of the limiting rod 305. An electromagnet 307 is provided on the second fixing seat 306, and the electromagnet 307 is attracted together with the first fixing seat 301. Through the attraction between the electromagnet 307 and the first fixing seat 301, and the insertion of the clamping groove 304 and the limiting rod 305, the conveying pipe 201 can be limited, so that the conveying pipe 201 maintains a stable position when it is upright.

[0033] Furthermore, the stirring structure includes two first support plates 101 mounted on the top of the stirring tank 1, and a first motor 102 mounted between the tops of the two first support plates 101. The output shaft of the first motor 102 is connected to a stirring shaft 103, and a plurality of stirring blades 104 are sleeved on the outer surface of the stirring shaft 103. The first motor 102 can drive the stirring blades 104 to rotate through the stirring shaft 103, so as to stir the material in the stirring tank 1 through the stirring blades 104.

[0034] Furthermore, a protective plate 105 is installed on one of the first support plates 101. The protective plate 105 is located on one side of the discharge pipe 203. When the discharge pipe 203 conveys materials into the mixing tank 1, the protective plate 105 can block the first motor 102.

[0035] Furthermore, several support columns 106 are installed at the bottom of the mixing tank 1, which are used to support the mixing tank 1.

[0036] Furthermore, a support base 4 is provided on one side of the mixing tank 1. When the conveying pipe 201 rotates horizontally, the support base 4 can support the conveying pipe 201.

[0037] The stirring device for catalyst production provided by this utility model is used as follows:

[0038] The material to be stirred is added into the stirring tank 1 and the first motor 102 and the second motor 204 are started. The first motor 102 drives the stirring blades 104 to rotate through the stirring shaft 103, so as to stir the material in the stirring tank 1 through the stirring blades 104. During this process, the second motor 204 drives the first gear 205 to rotate, so that the material in the stirring tank 1 is transported to the discharge pipe 203 through the connecting pipe 202 and the conveying pipe 201, and then returned to the stirring tank 1 through the discharge pipe 203, forming a circulation flow.

[0039] After mixing is complete, disconnect the electromagnet 307 and rotate the clamping plate 303 to separate the clamping slot 304 from the limiting rod 305. Start the third motor 207. The third motor 207 drives the connecting pipe 202 and the conveying pipe 201 to rotate through the second gear 206 and the first gear 205, so that the conveying pipe 201 rotates toward the support base 4 and is supported by the support base 4. The second motor 204 drives the first gear 205 to rotate, so that the material in the mixing tank 1 is conveyed to the discharge pipe 203 through the connecting pipe 202 and the conveying pipe 201, and then discharged from the discharge pipe 203.

[0040] After the material discharge is completed, the third motor 207 drives the connecting pipe 202 and the conveying pipe 201 to rotate through the second gear 206 and the first gear 205, so that the conveying pipe 201 rotates toward the second fixed seat 306. When the first fixed seat 301 contacts the second fixed seat 306, the rotating plate 303 causes the slot 304 to be inserted into the limiting rod 305, and the electromagnet 307 is attracted together with the first fixed seat 301.
