Description

Technical Field

[0001] This utility model relates to the field of acetate production technology, and in particular to a reaction vessel for acetate production. Background Technology

[0002] Acetate esters are products of the acetate ester class, which mainly refer to ethyl acetate and butyl acetate. They are widely used in solvents, plasticizers, surfactants and polymer monomers. When producing acetate esters, the raw materials need to be poured into a reaction vessel and stirred for reaction.

[0003] For example, a Chinese patent discloses an esterification reactor for the production of butyl acetate (publication number CN216987692U), which includes a reactor body, a plurality of support legs fixedly installed at the bottom of the reactor body, a connecting shell fixedly installed at the bottom of the reactor body, and a drive motor fixedly installed at the top of the reactor body.

[0004] However, the aforementioned publicly available documents demonstrate that the raw materials can be thoroughly mixed by incorporating worm gears, worm wheels, and rotating shafts. However, this patent cannot simultaneously agitate the materials vertically and horizontally, leading to uneven mixing and poor reaction results, thus limiting its practicality. Therefore, those skilled in the art have provided a reaction vessel for acetate production to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a reaction vessel for acetate production, which solves the problem mentioned in the background technology that it is impossible to simultaneously stir materials vertically and horizontally, which easily leads to uneven stirring, poor reaction effect, and low practicality.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a reaction vessel for acetate production, comprising a vessel body, a top cover provided on the outer top surface of the vessel body, a square cover provided inside the vessel body, a mixing component for stirring materials provided inside the square cover, a feed pipe fixedly and through-connected to the left end of the outer top surface of the top cover, and a discharge pipe fixedly and through-connected to the center of the outer bottom surface of the vessel body;

[0007] The mixing assembly includes a rotating shaft 1 rotatably mounted on the bottom surface of the inner side of a square cover. A bevel gear 1 is fixedly mounted on the outer wall of the rotating shaft 1. Rotating shafts 2 are rotatably mounted on both ends of the inner wall of the square cover. Bevel gears 2 are fixedly mounted on the outer walls of both rotating shafts 2. A through-hole is provided at the center of the outer top surface of the top cover. One end of the rotating shaft 1 extends rotatably to the bottom surface of the square cover, while the other end extends rotatably to the top surface of the top cover through the through-hole. The opposite ends of the two rotating shafts 2 pass through the square cover and are rotatably connected to the inner side wall of the vessel.

[0008] As a further technical solution of this utility model, an installation plate is fixed on the outer top surface of the top cover, and a rotating shaft three is rotatably installed inside the installation plate. A connecting sleeve is fixedly sleeved to the outside of the rotating shaft three by bolts. One end of the rotating shaft three is fixedly connected to the output end of the drive motor fixed on the outer top surface of the installation plate, while the other end is fixedly connected to the connecting sleeve. The bevel gear one is located below the two bevel gears two and meshes with each other.

[0009] As a further technical solution of this utility model, a cylinder is fixedly sleeved at the upper and lower ends of the outer peripheral sidewall of the first rotating shaft inside the vessel body. Stirring blades are symmetrically fixed on the outer peripheral sidewalls of the two cylinders and arranged in a linear array. A cylinder is fixedly sleeved on the outer peripheral sidewall of the two rotating shafts and arranged in a linear array. Stirring blades are symmetrically fixed on the outer peripheral sidewalls of the two cylinders.

[0010] As a further technical solution of this utility model, the front and rear outer walls of the square cover are fixedly connected to the inner wall of the vessel body by support rods, and the top cover and the vessel body are sealed and fixed to each other by multiple bolts.

[0013] This invention provides a reaction vessel for acetate production, which has the following advantages compared with the prior art:

[0014] 1. This design provides a reaction vessel for the production of acetate esters. A drive motor drives a rotating shaft three to rotate a rotating shaft one, which in turn drives a bevel gear one through a bevel gear two to rotate a rotating shaft two synchronously. This allows for vertical and horizontal mixing of the materials inside the vessel, achieving thorough mixing and improving practicality.

[0015] 2.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and 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 protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution for a reaction vessel for acetate production: it includes a vessel body 1, a top cover 101 on the outer top surface of the vessel body 1, a feed pipe 103 fixed and connected to the left end of the outer top surface of the top cover 101, and a discharge pipe 104 fixed and connected to the center of the outer bottom surface of the vessel body 1. The top cover 101 and the vessel body 1 are sealed and fixed to each other by multiple bolts. By tightening the multiple bolts, the top cover 101 can be sealed and fixed to the vessel body 1, which is convenient for disassembly for maintenance and cleaning of the vessel body 1 in the future. At the same time, valves (the valves are existing electrically controlled valves, and their working principle, model specifications and usage methods are not described in this article) are installed on the feed pipe 103 and the discharge pipe 104, which can be opened and closed to realize the feeding and discharging effects of the vessel body 1.

[0028] The interior of the vessel body 1 is equipped with a square cover 102. The front and rear outer walls of the square cover 102 are fixedly connected to the inner wall of the vessel body 1 via support plates 105. The square cover 102 is fixed inside the vessel body 1 via the support plates 105. The interior of the square cover 102 is equipped with a mixing component 2 for stirring materials. The mixing component 2 includes a rotating shaft 201 rotatably mounted on the inner bottom surface of the square cover 102. A bevel gear 202 is fixedly mounted on the outer wall of the rotating shaft 201. Rotating shafts 203 are rotatably mounted on both the left and right ends of the inner wall of the square cover 102. Bevel gears 204 are fixedly mounted on the outer walls of both rotating shafts 203. A through-hole 205 is opened at the center of the outer top surface of the top cover 101. One end of the rotating shaft extends to the outer bottom surface of the square cover 102, while the other end extends through the sleeve hole 205 to the outer top surface of the top cover 101. The opposite ends of the two rotating shafts 203 pass through the square cover 102 and are rotatably connected to the inner wall of the vessel body 1. The outer top surface of the top cover 101 is fixed with a mounting plate 206. The rotating shaft 207 is rotatably mounted inside the mounting plate 206. The outer side of the rotating shaft 201 is fixedly sleeved with a connecting sleeve 208 by bolts (the threaded connection of the bolts allows the rotating shaft 201 and the connecting sleeve 208 to be separated for easy disassembly and assembly later). One end of the rotating shaft 207 is fixedly connected to the output end of the drive motor 209 fixed on the outer top surface of the mounting plate 206, while the other end is connected to the connecting sleeve 208. The sleeve 208 is fixedly connected, with bevel gear 202 located below the two bevel gears 204 and meshing with each other. In use, first, the rotating shaft 201 passes through the sleeve hole 205 and is inserted into the inside of the sleeve 208 (after passing through the sleeve hole 205, the rotating shaft 201 is sealed by a gas rotating sealing ring, preventing air pressure leakage during rotation). Then, the bolts are tightened to secure them together. Next, the drive motor 209 is controlled and started to drive the rotating shaft 207 to rotate the rotating shaft 201, causing the rotating shaft 201 to drive the bevel gear 202 to rotate inside the square cover 102. Under the meshing connection characteristics of the bevel gear 202, the bevel gears 204 are driven to rotate the two bevel gears 204. The rotating shafts rotate synchronously, thus achieving a synchronous rotation effect. Inside the vessel body 1, at the upper and lower ends of the outer periphery of the rotating shaft 201, are fixedly fitted cylinders 210. The outer periphery of the two cylinders 210 is symmetrically fixed with linearly arranged stirring blades 211. The outer periphery of the two rotating shafts 203 is fixedly fitted with cylinders 212. The outer periphery of the two cylinders 212 is symmetrically fixed with linearly arranged stirring blades 213. When the rotating shafts 201 and 203 rotate synchronously, the cylinders 210 and 212 drive the stirring blades 211 and 213 to move synchronously in a circular motion, thereby mixing the material inside the vessel body 1 in both vertical and horizontal directions.This design achieves thorough mixing of materials, further improving practicality. Additionally, an arc-shaped stirring plate is fixed to the bottom of the outer wall of the rotating shaft 201, which can stir the inner bottom surface of the vessel body 1, preventing materials from settling at the bottom and affecting the mixing effect.

[0029] The vessel body 1 has a circular cavity 3 inside. The left end of the outer peripheral side wall of the vessel body 1 is connected to the circular cavity 3 through a water inlet pipe 301, and the right end of the outer bottom surface of the vessel body 1 is connected to the circular cavity 3 through a water outlet pipe 302. When stirring the raw materials, the operator introduces warm water into the circular cavity 3 through the water inlet pipe 301 and discharges it through the water outlet pipe 302. This cycle is used to heat the vessel body 1, keeping the material in a constant temperature environment and accelerating the reaction speed of the material. During the stirring process, the internal temperature of the vessel body 1 is displayed by a temperature display (the temperature display is existing technology, and its working principle, model specifications and usage methods will not be described in this article) installed on the front outer wall of the vessel body 1, so that the operator can adjust the warm water inside the circular cavity 3 in a timely manner.

[0030] A limiting ring 4 is fixedly sleeved on the outer peripheral side wall of the vessel body 1. Support rods 401 are fixedly installed at the four corners of the outer bottom surface of the limiting ring 4. The support rods 401 can be fixed by turning the bolts inside the screw holes on the support rods 401, thereby ensuring the stability of the vessel body 1 during the production and processing process.

[0031] The working principle of this utility model is as follows: When in use, first fix the vessel body 1 in the working area, then tighten multiple bolts to seal and fix the top cover 101 on the vessel body 1, and then tighten the bolts to fix the connecting sleeve 208 and the rotating shaft 201 to each other.

[0032] Simultaneously, the feed pipe 103 is opened to input the material into the interior of the vessel body 1. Then, the drive motor 209 is started to drive the rotating shaft 3 207 to rotate the rotating shaft 1 201. This causes the rotating shaft 1 201 to drive the bevel gear 1 202 to rotate inside the square cover 102, and drives the bevel gear 204 to drive the two rotating shafts to rotate synchronously. This causes the cylinder 1 210 and cylinder 2 212 to drive the stirring blade 1 211 and stirring blade 2 213 to move synchronously in a circular motion, so as to mix and stir the material inside the vessel body 1 in both vertical and horizontal directions, achieving the effect of fully mixing the material.

[0033] At the same time, the staff introduces warm water into the circular cavity 3 through the inlet pipe 301 and discharges it through the outlet pipe 302. This cycle is repeated to heat the vessel 1, keeping the material in a constant temperature environment and accelerating the reaction rate of the material.

[0034] After production is complete, simply open the discharge pipe 104 to discharge the material.

[0035] It should be noted that all electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
