Description

Technical Field

[0001] This utility model relates to the field of plasticizer production technology, specifically to a reaction vessel for producing plasticizers. Background Technology

[0002] Plasticizers are additives that increase the softness of materials. They can improve the toughness of the matrix material, increase the elongation at break of the product, and make the product softer during processing. At the same time, they can also greatly improve the processability of plastics, which is of great significance for the industrial production of certain plastic varieties that are particularly difficult to process.

[0003] As an important additive in plastic processing, the efficiency of material mixing and reaction during the production process of plasticizers directly affects the quality of products and production costs. Traditional plasticizer production reactors usually rely on a single stirring system to achieve material mixing. However, this mixing method has problems such as material sedimentation and uneven mixing, resulting in low reaction efficiency and unstable product quality. Due to gravity, materials tend to accumulate at the bottom of the reactor, making it difficult to achieve effective mixing and reaction, which affects product quality. Utility Model Content

[0004] This invention provides a reaction vessel for producing plasticizers. Through an anti-deposition mechanism, it can prevent plasticizer material from depositing at the bottom of the reaction vessel, achieving continuous circulation and uniform distribution of plasticizer material, effectively solving the problem of material deposition and improving the mixing uniformity of the material. Through the stirring mechanism inside the vessel, it can improve the stirring effect and the mixing uniformity of the material, avoiding unidirectional stirring and a single stirring method, which would cause uneven mixing and incomplete reaction of plasticizer material inside the vessel.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a reaction vessel for producing plasticizers, comprising:

[0023] 1. Pot body;

[0024] A stirring mechanism 2 is provided on the vessel body 1. The stirring mechanism 2 includes a rotating cylinder 201, a driving component, multiple sets of stirring components and multiple stirring rods 202. The rotating cylinder 201 is rotatably embedded on the top of the outer wall of the vessel body 1. The driving component is provided on the vessel body 1. Each set of stirring components is equidistantly arranged on the outer wall of the rotating cylinder 201 along the circumferential direction. Each stirring rod 202 is provided on the stirring component.

[0025] The anti-deposition mechanism 3 is located inside the rotating cylinder 201. The anti-deposition mechanism 3 includes a spiral conveying blade 301 and a rotating component. The rotating component is located on the rotating cylinder 201, and the spiral conveying blade 301 is located on the rotating component.

[0026] In this implementation scheme: the stirring mechanism 2 inside the vessel 1 improves the stirring effect and the uniformity of material mixing, avoiding unidirectional stirring and a single stirring method that leads to uneven mixing and insufficient reaction of the plasticizer material in the vessel 1. The rotating drum 201 is driven to rotate by the driving component, and the stirring rods 202 on each set of stirring components can stir the plasticizer material in the vessel 1, promoting the mixing reaction of the material. The anti-deposition mechanism 3 prevents the plasticizer material from depositing at the bottom of the reaction vessel, realizing continuous circulation and uniform distribution of the plasticizer material, effectively solving the problem of material deposition and improving the uniformity of material mixing. The rotating component drives the spiral conveyor blades 301 to rotate, which can lift the material deposited at the bottom of the reaction vessel to the top of the reaction vessel, avoiding the plasticizer material from easily accumulating at the bottom of the vessel 1 under the action of gravity, making it difficult to achieve effective mixing and reaction.

[0027] Specifically, the driving components include a rotary motor 203, a first gear 204, and a second gear 205. The rotary motor 203 is bolted to the top of the outer wall of the vessel body 1. The first gear 204 is fixedly sleeved on the output end of the rotary motor 203. The second gear 205 is fixedly sleeved on the outer wall of the rotating cylinder 201, and the second gear 205 meshes with the first gear 204.

[0028] In this embodiment: When the rotary motor 203 is powered on, it drives the first gear 204 to rotate, which in turn drives the second gear 205 to rotate. The second gear 205 drives the rotating cylinder 201 to rotate on the vessel body 1, so that the stirring rod 202 can mix and stir the plasticizer material in the vessel body 1.

[0029] Specifically, each set of stirring components includes a mounting frame 206 and a rotating component. The mounting frame 206 is fixedly installed on the outer wall of the rotating cylinder 201, and the rotating component is located inside the mounting frame 206.

[0030] In this embodiment: the mounting frame 206 is used for the installation and placement of the rotating component. The rotating component can drive the two stirring rods 202 on the mounting frame 206 to rotate in both directions, thereby improving the stirring effect and the uniformity of material mixing.

[0031] Specifically, each set of rotating components includes a stirring motor 207, a first bevel gear 208, and two second bevel gears 209. The stirring motor 207 is bolted to the inner wall of the mounting frame 206. The first bevel gear 208 is fixedly sleeved on the output end of the stirring motor 207. Each second bevel gear 209 is fixedly sleeved on the outer wall of the stirring rod 202, and each second bevel gear 209 meshes with the first bevel gear 208. Each stirring rod 202 is rotatably embedded in the top and bottom of the outer wall of the mounting frame 206.

[0032] In this embodiment: When the stirring motor 207 is powered on, it drives the first bevel gear 208 to rotate, which in turn drives the two second bevel gears 209 to rotate. Since each second bevel gear 209 is symmetrically arranged above and below the first bevel gear 208, when the first bevel gear 208 rotates, the two second bevel gears 209 can drive the stirring rod 202 to rotate in opposite directions, thereby improving the mixing effect and stirring efficiency of the material.

[0033] Specifically, the rotating components include a rotating motor 302, a rotating shaft 303, and two discharge pipes 304. The rotating motor 302 is bolted to the top of the outer wall of the rotating cylinder 201. The rotating shaft 303 is fixedly installed at the output end of the rotating shaft 303. Each discharge pipe 304 is fixedly installed on the outer wall of the rotating cylinder 201 near the top edge. The spiral conveying blades 301 are fixedly installed on the outer wall of the rotating shaft 303.

[0034] In this embodiment, the spiral conveying blade 301 is located on the inner wall of the rotating cylinder 201. When the rotating motor 302 is energized, it drives the rotating shaft 303 to rotate, causing the spiral conveying blade 301 to rotate inside the rotating cylinder 201. Through the pushing action of the spiral conveying blade 301, the material deposited at the bottom of the reactor can be lifted to the top of the reactor, realizing the continuous circulation and uniform distribution of plasticizer material, effectively solving the problem of material deposition.

[0035] Specifically, two scraper rods 4 are fixedly installed on the outer wall of the rotating cylinder 201.

[0036] In this embodiment: the plasticizer material adhering to the inner wall of the reactor body 1 is scraped off by the scraper 4.

[0037] In use, first start the rotary motor 203. The rotary motor 203 drives the first gear 204 to rotate, which in turn drives the second gear 205 to rotate the rotating cylinder 201 on the reactor body 1. Simultaneously, start the stirring motor 207. The stirring motor 207 drives the first bevel gear 208 to rotate, which in turn drives the two second bevel gears 209 to rotate in opposite directions. The two second bevel gears 209 drive the stirring rod 202 to rotate in opposite directions, which can improve the stirring effect and the uniformity of material mixing, avoiding unidirectional stirring and a single stirring method. At the same time, start the rotary motor 302. The rotary motor 302 drives the rotating shaft 303 to rotate, which causes the spiral conveying blades 301 to rotate inside the rotating cylinder 201. Through the pushing action of the spiral conveying blades 301, the material deposited at the bottom of the reactor can be lifted to the top of the reactor, realizing the continuous circulation and uniform distribution of plasticizer material, effectively solving the problem of material deposition.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
