Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a reactor based on water bath heating. Background Art

[0002] A reactor is a closed container used for chemical reactions. It can complete the reaction between materials by stirring under certain pressure, temperature and other specific conditions. In order to stably control the reaction temperature, a water bath is often used to provide a preset temperature to the raw materials inside the reactor. In the existing reactor, when the material in the reactor is stirred by a stirring shaft to accelerate the reaction, a spiral water bath heating tube is arranged on the outer wall of the reactor, and the flowing medium in the water bath heating tube provides the raw materials in the reactor with the required temperature for the reaction. However, since the existing water bath heating tube is only arranged on the outer wall of the reactor, the heat is transferred from the outside to the inside. Therefore, in order to ensure that the raw materials are heated evenly during the reaction, the reactor is often required to be preheated, that is, the reactor is heated in advance by the water bath heating tube. Moreover, during the reaction of the raw materials, the outermost part, that is, the part close to the water bath heating tube, is heated significantly higher than the middle part of the reactor, resulting in uneven heating when the raw materials react.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a reactor based on water bath heating is proposed. Summary of the invention

[0008] Furthermore, one end of the pipeline is connected to an external water bath heating pipe, and the external water bath heating pipe is connected to a heating water tank through a pipeline and a pump body.

[0009] Furthermore, a feed pipe is arranged on one side of the top surface of the reactor upper cover, a discharge pipe is arranged at the bottom of the reactor tank body, and a solenoid valve is arranged in the middle of the discharge pipe.

[0010] Furthermore, a stirring assembly is fixed to the middle of the top surface of the reactor cover, and the stirring assembly includes a driving motor, an electric telescopic rod and a stirring shaft. The driving motor is connected to the electric telescopic rod through the output shaft at the bottom of the driving motor, and the bottom of the electric telescopic rod is connected to the stirring shaft.

[0011] Furthermore, the stirring shaft passes through the interior of the inner water bath heating tube, the water bath heating assembly also includes a connecting bearing, and the outer wall of the stirring shaft is sleeved with a connecting bearing.

[0015] The present invention provides a reaction kettle based on water bath heating, which has the following beneficial effects: 1. The reactor based on water bath heating has an inner water bath heating pipe connected to the outer water bath heating pipe added inside the reactor tank body, so that the flowing medium can release heat from the outside to the inside and from the inside to the outside of the reactor at the same time during the flow process, which is conducive to accelerating the heating efficiency of various areas inside the reactor, thereby greatly shortening the preheating time inside the reactor, and the inner water bath heating pipe has a spiral structure, which is convenient for the stirring shaft to pass through, and can avoid interference between the stirring shaft and the inner water bath heating pipe when it rotates.

[0019] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figure 1-Figure 6As shown, the present invention provides a technical solution: a reactor based on water bath heating, comprising a reactor tank body 1 and a water bath heating component 3, a reactor upper cover 2 is arranged on the upper part of the reactor tank body 1, the water bath heating component 3 is arranged outside the reactor tank body 1, the water bath heating component 3 comprises an insulation box 301, an outer water bath heating pipe 302, a water inlet bellows 303, an inner water bath heating pipe 304, a drainage bellows 305, a drainage pipe 306, a heating water tank 307, a pipeline 308 and a pump body 309, an outer water bath heating pipe 302 is arranged inside the insulation box 301, and the end of the outer water bath heating pipe 302 is penetrated into the reactor tank body 1 and connected to the water inlet bellows 303, the end of the water inlet bellows 303 is connected to the inner water bath heating pipe 304, and the end of the inner water bath heating pipe 304 away from the water inlet bellows 303 is connected to the drainage bellows 305, the drainage bellows The end of 305 is connected with a drain pipe 306, and the end of the drain pipe 306 penetrates through the reactor tank body 1 and the side wall of the insulation box 301 and is connected to a heating water tank 307. A pipe 308 is provided on one side of the heating water tank 307, and a pump body 309 is provided in the middle of the pipe 308. The outer water bath heating pipe 302 is sleeved on the outer wall of the reactor tank body 1, and the outer water bath heating pipe 302 has a spiral structure. The inner water bath heating pipe 304 has a spiral structure, and the inner water bath heating pipe 304 is connected to the outer water bath heating pipe 302 through the water inlet bellows 303. One end of the pipe 308 is connected to the outer water bath heating pipe 302, and the outer water bath heating pipe 302 is connected to the heating water tank 307 through the pipe 308 and the pump body 309. A feed pipe 4 is provided on one side of the top surface of the reactor upper cover 2, and a discharge pipe 5 is provided at the bottom of the reactor tank body 1, and a solenoid valve 6 is provided in the middle of the discharge pipe 5; The specific operation is as follows: first, the solenoid valve 6 at the bottom of the reactor tank body 1 is closed, and the raw materials participating in the reaction are injected into the reactor tank body 1 through the feed pipe 4. The pump body 309 is started to heat the inside of the heating water tank 307 to a certain temperature. The flowing medium, such as water, enters the outer water bath heating pipe 302 along the pipe 308. The flowing medium heats the inside of the reactor tank body 1 during the flow along the inner part of the outer water bath heating pipe 302, and is kept warm by the insulation box 301. As the flowing medium flows along the outer water bath heating pipe 302 and the water inlet bellows 303 to the inner water bath heating pipe 304, the inner water bath heating pipe 304 is located inside the reactor tank body 1, and thus the flowing medium flowing along the inner water bath heating pipe 304 releases heat inside the reactor tank body 1. Thus, the reactor is heated from the outside to the inside and from the inside to the outside at the same time, so that the raw materials can be quickly heated, which is conducive to quickly heating each position inside the reactor tank body 1 to the same temperature threshold; As the flowing medium continues to flow, the flowing medium passes through the inner water bath heating pipe 304, the drainage bellows 305, and the drainage pipe 306 in sequence and returns to the inside of the heating water tank 307. At this time, the heat of the flowing medium is compensated by the heating water tank 307, so that the temperature of the flowing medium is maintained when it enters the next cycle. Based on the above description, the present invention adds an inner water bath heating tube 304 connected to the outer water bath heating tube 302 inside the reactor tank body 1, so that the flowing medium can release heat from the outside to the inside and from the inside to the outside of the reactor at the same time during the flow process, which is beneficial to speed up the heating efficiency of various areas inside the reactor, thereby greatly shortening the preheating time inside the reactor. In addition, the spiral structure of the inner water bath heating tube 304 is convenient for the stirring shaft 703 to pass through, and at the same time, it can avoid interference between the stirring shaft 703 and the inner water bath heating tube 304 when it rotates.

[0021] like Figure 1-Figure 6 As shown, a stirring assembly 7 is fixed to the middle of the top surface of the reactor upper cover 2, and the stirring assembly 7 includes a driving motor 701, an electric telescopic rod 702 and a stirring shaft 703. The driving motor 701 is connected to the electric telescopic rod 702 through the output shaft at the bottom thereof, and the bottom of the electric telescopic rod 702 is connected to the stirring shaft 703, and the stirring shaft 703 passes through the interior of the inner water bath heating tube 304. The water bath heating assembly 3 also includes a connecting bearing 310, and the outer wall of the stirring shaft 703 is provided with a connecting bearing 310. The water bath heating assembly 3 also includes a connecting bracket 31 1. The outer wall of the connecting bearing 310 is connected with a connecting bracket 311, the outer side surface of the connecting bracket 311 is connected to the inner side surface of the inner water bath heating tube 304, and there are two connecting brackets 311, which are respectively arranged at the top and bottom of the inner water bath heating tube 304, and the bottom end of the stirring shaft 703 is located at a height lower than the bottom of the inner water bath heating tube 304, and the inner water bath heating tube 304 forms a transmission structure through the connecting bracket 311, the connecting bearing 310, the stirring shaft 703, the electric telescopic rod 702 and the driving motor 701; The specific operation is as follows: first, the electric telescopic rod 702 is an electric telescopic rod with a built-in battery. When raw materials are put into the reactor tank body 1 and the temperature monitoring reaches a preset threshold, the driving motor 701 drives the electric telescopic rod 702 to rotate the stirring shaft 703. The stirring shaft 703 rotates to stir the raw materials to accelerate the mixing reaction between the raw materials, and at the same time avoid the raw materials being in the same temperature area for a long time, resulting in uneven heating; Since the water inlet bellows 303 and the drainage bellows 305 are both flexible structures and cannot support the inner water bath heating pipe 304, a connecting bearing 310 is sleeved on the outer wall of the rod body of the stirring shaft 703 and connected to the inner water bath heating pipe 304 through a connecting bracket 311, wherein the connecting bearing 310 is composed of an outer ring, an inner ring and a ball, the inner ring is fixedly connected to the outer wall of the stirring shaft 703, the outer ring is fixedly connected to the connecting bracket 311, and a ball is embedded between the outer ring and the inner ring, so that the inner ring and the outer ring do not interfere with each other, and the water inlet bellows 303 and the drainage bellows 305 are 5 is vertically arranged with a telescopic rod inside, so that when the stirring shaft 703 rotates, the inner ring of the connecting bearing 310 rotates, but the outer ring of the connecting bearing 310 is fixedly connected to the connecting bracket 311 and does not interfere with the movement of the inner ring through the ball, and the connecting bracket 311 is fixedly connected to the inner water bath heating pipe 304, so it is restricted by the telescopic rod inside the water inlet bellows 303 and the drain bellows 305, resulting in the inner water bath heating pipe 304 being unable to rotate horizontally with the stirring shaft 703, and the connecting bearing 310 is used to avoid interference with the rotation of the stirring shaft 703; As the electric telescopic rod 702 is started to extend and retract, the stirring shaft 703 and the inner water bath heating tube 304 are synchronously lifted and lowered. During the lifting and lowering process of the inner water bath heating tube 304, the water inlet bellows 303, the water discharge bellows 305 and the telescopic rod inside thereof are extended and retracted accordingly, so that the inner water bath heating tube 304 can continuously release heat from the inside to the outside of the reactor tank body 1 at different height positions. The lifting and lowering of the inner water bath heating tube 304 and the rotation of the stirring shaft 703 to stir the raw materials cooperate with each other, so that when the stirring shaft 703 no longer stirs the raw materials, for example, when the raw materials are precipitated and stationary, the inner water bath heating tube 304 can avoid that part of the raw materials are always attached to the periphery of the inner water bath heating tube 304 and are overheated; Based on the above description, the present invention stirs the raw materials through the rotation of the stirring shaft 703 to accelerate the mixing reaction between the raw materials, while preventing the raw materials from being in the same temperature area for a long time and causing uneven heating. As the electric telescopic rod 702 is started and extended, the stirring shaft 703 carries the inner water bath heating tube 304 to rise and fall synchronously, so that the inner water bath heating tube 304 is started and extended by the electric telescopic rod 702. When the stirring shaft 703 no longer stirs the raw materials, for example, when they are precipitated and stationary, it can also prevent part of the raw materials from always sticking to the periphery of the inner water bath heating tube 304 and being overheated.

[0022] In summary, when the reactor based on water bath heating is used, the solenoid valve 6 is first closed, and the raw materials participating in the reaction are injected into the reactor tank body 1 through the feed pipe 4. The pump body 309 is started to heat the inside of the heating water tank 307 to a certain temperature. The flowing medium, such as water, enters the outer water bath heating pipe 302 along the pipe 308. The flowing medium heats the inside of the reactor tank body 1 during the flow along the inner part of the outer water bath heating pipe 302, and is kept warm by the insulation box 301. As the flowing medium flows along the outer water bath heating pipe 302 and the water inlet bellows 303 to the inner water bath heating pipe 304, the inner water bath heating pipe 304 is located inside the reactor tank body 1, and thus the flowing medium flowing along the inner water bath heating pipe 304 releases heat inside the reactor tank body 1. Thus, the reactor is heated from the outside to the inside and from the inside to the outside at the same time, so that the raw materials can be quickly heated, which is conducive to quickly heating each position inside the reactor tank body 1 to the same temperature threshold; As the flowing medium continues to flow, the flowing medium passes through the inner water bath heating pipe 304, the drainage bellows 305, and the drainage pipe 306 in sequence and returns to the inside of the heating water tank 307. At this time, the heat of the flowing medium is compensated by the heating water tank 307, so that the temperature of the flowing medium is maintained when it enters the next cycle. When raw materials are put into the reactor tank 1 and the temperature monitoring reaches a preset threshold, the driving motor 701 drives the electric telescopic rod 702 to rotate the stirring shaft 703, and the stirring shaft 703 rotates to stir the raw materials to accelerate the mixing reaction between the raw materials, while preventing the raw materials from being in the same temperature zone for a long time, resulting in uneven heating; As the electric telescopic rod 702 is started and extended, the stirring shaft 703 and the inner water bath heating tube 304 are synchronously lifted and lowered. During the lifting process of the inner water bath heating tube 304, the water inlet bellows 303, the water discharge bellows 305 and the telescopic rod inside thereof are extended and retracted accordingly, so that the inner water bath heating tube 304 can continuously release heat from the inside to the outside inside the reactor tank body 1 at different heights. The lifting of the inner water bath heating tube 304 and the rotation of the stirring shaft 703 to stir the raw materials cooperate with each other, so that the inner water bath heating tube 304 can be started and extended by the electric telescopic rod 702 when the stirring shaft 703 no longer stirs the raw materials, for example, when the raw materials are precipitated and stationary, so that part of the raw materials can be prevented from always sticking to the periphery of the inner water bath heating tube 304 and being overheated.
