Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, and specifically relates to a temperature-controlled chemical reaction kettle. Background Art

[0002] A reaction kettle is a container specifically used for carrying out chemical reactions. It is usually made of stainless steel and has good high-temperature resistance and corrosion resistance. After retrieval, a patent with the Chinese patent publication number CN219722854U discloses an intelligent temperature-controlled chemical reaction kettle. Although a second coil pipe is arranged in the pipe cavity of the reaction kettle body, and a first coil pipe is also arranged on the spiral blade, so that the spiral blade can heat the reactants in the reaction cavity while stirring and mixing, enabling the reactants in the reaction cavity to be effectively heated, making the reactants heated more evenly, improving the reaction rate, and greatly improving the product quality, the stirring property of the spiral blade on the internal materials of the reaction kettle is poor, resulting in the need to greatly increase the rotation speed of the spiral blade to maintain good mixing reaction of the internal materials. However, the motor is prone to a shortened service life when used under high load for a long time. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a temperature-controlled chemical reaction kettle, which solves the problem that the existing reaction kettle needs to greatly increase the rotation speed of the spiral blade to maintain good mixing reaction of the internal materials, but the motor is prone to a shortened service life when used under high load for a long time as mentioned in the background art.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A temperature-controlled chemical reaction kettle includes a reaction kettle body, a jacket, an air groove, a lifting cage, and a deflector. The outer wall of the reaction kettle body is welded with a jacket. One side of the bottom of the jacket is provided with a drain port, and one side of the top of the jacket is provided with a water inlet. Both sides of the jacket are welded with brackets. A driving motor is installed on the top of the reaction kettle body. One side of the driving motor is provided with a feed port, and the feed port is communicated with the inside of the reaction kettle body. The outer part of the output end of the driving motor at the bottom is sleeved with a stirring shaft, and the stirring shaft is located inside the reaction kettle body. A discharge port is opened at the bottom of the reaction kettle body, and an air pump is arranged on one side of the bottom of the reaction kettle body. The air pump is communicated with one end of the bottom of a connecting pipe through a control valve, and the other end of the connecting pipe is communicated with the inside of the air groove. The air groove is welded to the bottom of the reaction kettle body. A lifting cage is arranged inside the reaction kettle body. A pressure relief valve is arranged on the top of the reaction kettle body to discharge the excess gas inside, and the gas pumped into by the air pump is an inert gas, which is beneficial to avoiding oxidation reaction on the internal materials.

[0005] Preferably, the lifting cage is made of stainless steel, and the outer wall surface of the lifting cage is evenly provided with hole grooves, and the bottom of the lifting cage is open. The inside of the lifting cage is of a hollow structure, which is conducive to the upward movement of the lifting cage after being pushed by the air pressure inside the air groove.

[0006] Preferably, the lifting cages are distributed in an annular and equally spaced manner inside the air groove, and the outer wall surface of the lifting cage is in sliding contact with the air groove. Ring-shaped protruding structures are provided on the outer sides of one ends of the bottom and top of the lifting cage. The ring shape at the bottom of the lifting cage is conducive to limiting the lifting stroke of the lifting cage.

[0007] Preferably, the top of the lifting cage is slidably connected to the sliding rod. The bottom of the sliding rod is welded to the air groove. One end of the top of the sliding rod is welded to one end of the connecting arm. The other end of the connecting arm is welded to the outer wall of the air groove. A spring is sleeved outside the sliding rod. The spring is located at the top of the lifting cage. When there is no air pressure inside the air groove, under the push of the spring, the lifting cage can quickly move downward to reset, which is conducive to preventing the liquid inside the reaction kettle from entering the air groove.

[0008] Preferably, a flow guide plate is welded to the outside of the air groove. The flow guide plate is of a hopper-shaped structure and is welded to the vertical plate. The vertical plates are distributed in an annular and equally spaced manner. One side of the vertical plate is welded to the inner wall of the reaction kettle body, which is conducive to enabling the materials inside the reaction kettle body to flow to the discharge port through the surface of the flow guide plate, so that the internal materials can be fully discharged.

[0009] Preferably, there is a gap between the inner wall of the jacket and the outer wall of the reaction kettle body. A plurality of fins are welded to the outer wall of the reaction kettle at equal intervals from top to bottom. The fins are of a ring-shaped structure and are made of copper-aluminum composite material. There is a gap between the outside of the fins and the inside of the jacket. The fins are conducive to increasing the heat exchange surface of the outer wall of the reaction kettle body.

[0010] The utility model provides a temperature-controlled chemical reaction kettle, which has the following beneficial effects:

[0011] (1). In this temperature-controlled chemical reaction kettle, materials enter the inside of the reaction kettle body through the feed port. Then, the driving motor drives the stirring shaft to rotate, so that the stirring shaft can drive the materials inside the reaction kettle body to react and mix. At the same time, the air pump pumps high-pressure gas into the air groove through the connecting pipe. Then, the high-pressure gas will push the lifting cage upward, so that the hole grooves on the surface of the lifting cage can be exposed. Then, the air becomes dense bubbles through the hole grooves on the surface of the lifting cage and rises inside the reaction kettle body. During the rising process of the bubbles inside the reaction kettle, they keep rolling and disturbing the mixed materials, thereby improving the mixing reaction efficiency of the mixed materials. As a result, the driving motor only needs a very small rotation speed to quickly and fully mix and react the materials inside the reaction kettle body, which is conducive to extending the service life of the driving motor.

[0012] (2) In this temperature-controlled chemical reactor, the external heating water or cooling water enters the inside of the jacket through the water inlet to heat or cool the reactor. Meanwhile, the fins on the outer wall of the reactor are beneficial to increasing the heat exchange surface between the reactor body and the heating water, thereby improving the heat exchange efficiency of the reactor, and further improving the accuracy of the temperature control of the reactor body. At the same time, the vertical plates on the inner wall of the reactor body are beneficial to increasing the heat exchange contact surface with the internal materials. The reactor body can transfer the temperature to the vertical plates to exchange heat with the internal materials, which is conducive to further improving the heat exchange effect and further improving the accuracy of temperature control. Moreover, when the stirring shaft stirs the internal materials, the materials will collide with the vertical plates while being stirred, thereby increasing the disturbance of the materials and improving the mixing reaction efficiency of the materials.

[0013] Thus, it solves the problem that the existing reactor needs to significantly increase the rotation speed of the spiral blades to maintain good mixing reaction of the internal materials, but the motor is prone to a shortened service life when used under high load for a long time.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1:

[0023] Please refer to Figure 1-6 , a temperature-controlled chemical reactor, comprising a reactor body 1, a jacket 2, a gas tank 14, a lifting cage 15 and a baffle 19. A driving motor 8 is installed on the top of the reactor body 1. One side of the driving motor 8 is provided with a feed inlet 7, and the feed inlet 7 is communicated with the inside of the reactor body 1. The outer part of the bottom output end of the driving motor 8 is sleeved with a stirring shaft 9, and the stirring shaft 9 is located inside the reactor body 1. A discharge port 5 is opened at the bottom of the reactor body 1, and an air pump 13 is arranged on one side of the bottom of the reactor body 1. The air pump 13 is communicated with one end of the bottom of a connecting pipe 20 through a control valve 12, and the other end of the connecting pipe 20 is communicated with the inside of the gas tank 14. The gas tank 14 is welded to the bottom of the reactor body 1. A lifting cage 15 is arranged inside the reactor body 1. The lifting cage 15 is made of stainless steel, and the outer wall surface of the lifting cage 15 is evenly provided with hole grooves, and the bottom of the lifting cage 15 is open. The inside of the lifting cage 15 is of a hollow structure. The lifting cages 15 are distributed in an annular equidistant manner inside the gas tank 14, and the outer wall surface of the lifting cage 15 is in sliding contact with the gas tank 14. Annular protruding structures are arranged on the outer sides of one ends of the bottom and the top of the lifting cage 15. The top of the lifting cage 15 is slidably connected with a sliding rod 18. The bottom of the sliding rod 18 is welded to the gas tank 14, and one end of the top of the sliding rod 18 is welded to one end of a connecting arm 17. The other end of the connecting arm 17 is welded to the outer wall of the gas tank 14, and a spring 16 is sleeved on the outside of the sliding rod 18. The spring 16 is located at the top of the lifting cage 15. The driving motor 8 drives the stirring shaft 9 to rotate, so that the stirring shaft 9 can drive the materials inside the reactor body 1 to react and mix. At the same time, the air pump 13 pumps high-pressure gas into the gas tank 14 through the connecting pipe 20. Then, the high-pressure gas will push the lifting cage 15 upward, so that the hole grooves on the surface of the lifting cage 15 can be exposed. Then, the air becomes dense bubbles through the hole grooves on the surface of the lifting cage 15 and rises inside the reactor body 1. The bubbles continuously roll during the rising process inside the reactor and disturb the mixed materials, thereby improving the mixing and reaction efficiency of the mixed materials, so that the driving motor 8 only needs a very small rotation speed to quickly and fully mix and react the materials inside the reactor body 1.

[0024] Embodiment 2:

[0025] A jacket 2 is welded to the outer wall of the reactor body 1. A drain port 4 is provided on one side of the bottom of the jacket 2, and a water inlet 3 is provided on one side of the top of the jacket 2. Both sides of the jacket 2 are welded to the support 6. A deflector 19 is welded to the outside of the air groove 14. The deflector 19 is in a funnel-shaped structure and is welded to the vertical plate 10. The vertical plates 10 are distributed at equal intervals in a ring shape. One side of the vertical plate 10 is welded to the inner wall of the reactor body 1. There is a gap between the inner wall of the jacket 2 and the outer wall of the reactor body 1. Multiple fins 11 are welded to the outer wall of the reactor at equal intervals from top to bottom. The fins 11 are in a ring-shaped structure and are made of copper-aluminum composite material. There is a gap between the outside of the fins 11 and the inside of the jacket 2. External heating water or cooling water enters the inside of the jacket 2 through the water inlet 3 to heat or cool the reactor. At the same time, the fins 11 on the outer wall of the reactor are beneficial to increasing the heat exchange surface between the reactor body 1 and the heating water, thereby improving the heat exchange efficiency of the reactor, and thus improving the accuracy of temperature control of the reactor body 1. At the same time, the reactor body 1 is beneficial to increasing the heat exchange contact surface with the internal materials through the vertical plates 10 on the inner wall. The reactor body 1 can transfer the temperature to the vertical plates 10 to exchange heat with the internal materials, which is beneficial to further improving the heat exchange effect and further improving the accuracy of temperature control. And when the stirring shaft 9 stirs the internal materials, the materials will collide with the vertical plates 10 while being stirred, thereby increasing the disturbance of the materials and thus improving the mixing reaction efficiency of the materials.

[0026] Working principle: The materials enter the inside of the reactor body 1 through the feed port 7. Then, the driving motor 8 drives the stirring shaft 9 to rotate, so that the stirring shaft 9 can drive the materials inside the reactor body 1 to react and mix. At the same time, the air pump 13 pumps high-pressure gas into the air groove 14 through the connecting pipe 20. Then, the high-pressure gas will push the lifting cage 15 upward, so that the holes on the surface of the lifting cage 15 can be exposed. Then, the air becomes dense bubbles through the holes on the surface of the lifting cage 15 and rises inside the reactor body 1. The bubbles keep tumbling during the rising process inside the reactor, disturbing the mixed materials, thereby improving the mixing reaction efficiency of the mixed materials. During the reaction, external heating water or cooling water enters the inside of the jacket 2 through the water inlet 3 to heat or cool the reactor, so as to control the reaction temperature.
