Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a uniformly stirred reaction vessel. Background Technology

[0002] A reaction vessel is a device used in industries such as chemical, pharmaceutical, food, and building materials to achieve physical or chemical reactions. This device controls conditions such as temperature, pressure, and stirring to transform raw materials into target products in a closed or open environment.

[0003] Some reactors have baffles installed vertically on their inner walls (the width of the baffles is 1 / 10-10 / 20 of the reactor diameter, and the number is usually 4-8). By increasing turbulence, the fluid rotation is disrupted, and the tangential flow is converted into radial and axial flow, thereby improving the mixing uniformity of the reactor.

[0004] However, due to differences in viscosity, density, and phase state of different materials, as well as the requirements of the reaction stage, the stirring speed needs to be dynamically adjusted. At low speeds, high-viscosity materials or suspensions containing solid particles may form dead zones between the baffle and the inner wall of the vessel due to insufficient flow, resulting in excessively high local concentrations or incomplete reactions, which in turn affects the overall reaction effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a uniformly stirred reaction vessel to reduce the dead angles formed between the baffle and the vessel body when the stirring rod rotates at low speed, which can lead to excessively high local concentrations or incomplete reactions.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a uniformly stirred reaction vessel, including a vessel body, a vessel cover, a rotating rod, and a first stirring blade. The bottom end of the vessel body is provided with a discharge port. The bottom end of the rotating rod is fixedly connected to a second stirring blade. An electric push rod is fixedly connected to one side of the upper end of the vessel cover. A feed port is fixedly connected to the upper end of the vessel cover away from the electric push rod. A connecting plate is fixedly connected to the upper end of the electric push rod. Support rods are fixedly connected to the four sides of the bottom end of the connecting plate. A movable ring is fixedly connected to the bottom end of the support rod. A stop bar is contacted on the four sides of the bottom end of the movable ring. A hidden groove is opened on the upper end of the stop bar. A pressure rod is threadedly connected to the stop bar in the hidden groove. The pressure rod is inserted into the movable ring.

[0007] As a preferred technical solution of this utility model, a guide cover is fixedly connected inside the kettle lid, and a material distribution frame is fixedly connected to the bottom end of the guide cover. The material distribution frame is rotatably connected to a rotating rod, and material dispersing holes are evenly opened on the bottom side of the material distribution frame. By setting the guide cover and the material distribution frame, the material can be dispersed and guided, and the feeding can be controlled.

[0008] As a preferred technical solution of this utility model, a scraper is in contact with the bottom side of the material distribution frame. The scraper is fixedly connected to the rotating rod. By setting the scraper, uniform material distribution can be achieved.

[0009] As a preferred technical solution of this utility model, a folding cover is fixedly connected to the upper end of the kettle lid, and the upper end of the folding cover is fixedly connected to the connecting plate. The folding cover is located outside the support rod. By setting the folding cover, the amount of dust from the external environment entering the kettle body from the gap between the kettle lid and the support rod can be reduced.

[0010] As a preferred technical solution of this utility model, auxiliary rods are fixedly connected to the four sides of the bottom end of the movable ring. The bottom side of the auxiliary rods is fixedly connected to the baffle through the connecting rod. By setting the auxiliary rods, the effect of the baffle in stable contact with the inner wall of the vessel can be further increased.

[0011] This invention has the following advantages: by setting baffles inside the vessel body and the vessel lid to cooperate with the first and second stirring blades to form turbulence, and then extending the electric push rod to control the connecting plate, moving ring and baffles to move upward, thereby reducing the dead angle between the baffle and the vessel body at low speeds and improving the full reaction of the material.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The reactor shown includes a vessel body 1, a vessel lid 2, a rotating rod 3, and a first stirring blade 4. A discharge port is located at the bottom of the vessel body 1. The rotating rod 3 is controlled by a motor, and a second stirring blade 5 is fixedly connected to the bottom of the rotating rod 3. The second stirring blade 5 is close to the bottom side of the inner wall of the vessel body 1, thereby increasing the stirring effect and reducing material deposition at the bottom side of the vessel body 1. An electric push rod 6 is fixedly connected to one side of the upper end of the vessel lid 2. Extending the electric push rod 6 causes the connecting plate 7, support rod 8, moving ring 9, and baffle 10 to move upwards. Therefore, when the rotating rod 3 rotates at low speed, the baffle 10 no longer contacts the inner wall of the vessel body 1, enabling... To reduce dead-angle molding, a feed inlet 13 is fixedly connected to the upper end of the vessel lid 2 on the side away from the electric push rod 6. The feed inlet 13 is used for material input. A connecting plate 7 is fixedly connected to the upper end of the electric push rod 6. Support rods 8 are fixedly connected to the four sides of the bottom end of the connecting plate 7. A moving ring 9 is fixedly connected to the bottom end of the support rod 8. A stop bar 10 is in contact with the four sides of the bottom end of the moving ring 9. A hidden groove 12 is opened at the upper end of the stop bar 10. A pressure rod 11 is threadedly connected to the stop bar 10 in the hidden groove 12. By disassembling the pressure rod 11, the stop bar 10 can be separated from the moving ring 9 for easy disassembly and cleaning. The pressure rod 11 is inserted into the moving ring 9.

[0018] The vessel lid 2 is fixedly connected to a guide cover 14, and the bottom of the guide cover 14 is fixedly connected to a material distribution frame 15. The material distribution frame 15 is rotatably connected to a rotating rod 3. The bottom side of the material distribution frame 15 is evenly provided with material dispersing holes. The material entering from the feed inlet 13 falls from the guide cover 14 into the material distribution frame 15, and then falls automatically under gravity.

[0019] The bottom side of the material distribution frame 15 is in contact with a scraper 19, which is fixedly connected to the rotating rod 3. By setting a motor to drive the scraper 19 to rotate, the material falling on the material distribution frame 15 can be dispersed and dropped.

[0020] The upper end of the lid 2 is fixedly connected to a folding cover 18, and the upper end of the folding cover 18 is fixedly connected to the connecting plate 7. The folding cover 18 is located outside the support rod 8. By setting the folding cover 18, the amount of dust from the external environment entering the body 1 can be reduced.

[0021] Among them, auxiliary rods 16 are fixedly connected to the four sides of the bottom of the movable ring 9. The bottom side of the auxiliary rods 16 is fixedly connected to the baffle 10 through the connecting rods 17. The connecting rods 17 are threaded to the baffle 10. By setting the auxiliary rods 16, the baffle 10 can be stably contacted with the inner wall.

[0022] Working principle: The material enters the guide cover 14 and the distribution frame 15 through the feed inlet 13. Then, according to the stage of material mixing, the rotating rod 3 rotates to make the powder fall from the dispensing hole. The rotating rod 3 is controlled by the motor to rotate, which makes the first stirring blade 4 and the second stirring blade 5 rotate, thereby mixing the material. When the speed is low, the first stirring blade 4 and the second stirring blade 5 rotate at low speed, and the electric push rod 6 extends to make the connecting plate 7 and the moving ring 9 move upward, and the baffle 10 moves upward to no longer contact the solvent, thereby avoiding dead corners. This can achieve the goal of improving the concentration and mixing uniformity when mixing high viscosity materials at low speed, which is due to insufficient flow and the formation of dead corners between the baffle 10 and the inner wall of the vessel body 1.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
