Description

Technical Field

[0001] The invention relates to a reaction kettle in the technical field of reaction treatment, in particular to a central heating type reaction kettle. Background Art

[0002] In the prior art, most reactors need to heat the liquid inside when carrying out the reaction process, so that the internal liquid can reach a certain temperature before a better chemical reaction can be carried out. In the prior art, a heating element is usually directly installed inside the reactor to achieve internal heating of the reactor.

[0003] For example: the "electrically heated reactor" disclosed in the publication (announcement) number: CN102671612A, the technical solution includes a hollow reactor body, and a plurality of electric heating devices are arranged on the inner wall of the reactor body, characterized in that: the electric heating device includes a block-shaped resistor connected to a power source, and the resistor is sequentially covered with an insulating layer and a heat-conducting layer. The electric heating reactor of the present invention adopts a block-shaped resistive electric heating device, which can be covered with a thicker corrosion-resistant and wear-resistant heat-conducting layer made of pure titanium, thereby greatly increasing the normal working time of the electric heating device and improving the working efficiency of the reactor. The electric heating reactor of the present invention has the advantages of high efficiency and environmental protection.

[0004] For example: the "An electromagnetic induction heating reactor" disclosed in the publication (announcement) number: CN105617964B, the technical solution includes a kettle body for placing materials, a stirring device placed in the kettle body for stirring materials, and a bracket connected to the bottom of the kettle body for supporting the kettle body, the kettle body includes a kettle body bottom shell and a kettle body upper shell installed on the kettle body bottom shell, wherein the electromagnetic induction heating reactor also includes an electromagnetic induction heating coil connected to a high-frequency power supply, the electromagnetic induction heating coil is suspended below the kettle body bottom shell and is electrically insulated from the kettle body bottom shell to heat the kettle body bottom shell. The present invention utilizes electromagnetic induction heating technology, by arranging an electromagnetic induction heating coil at the bottom of the kettle body as a heating source to replace the boiler room steam supply, with high thermal efficiency, large power adjustment range, heating temperature up to 250 ° C, and no steam condensate water is involved in the material, achieving high efficiency, strong controllability and no good effects of introducing pollutants.

[0005] However, the heating method of the reactor in the above technical solution is to heat from the side wall of the reactor to the inside. The first part to be heated is the side wall of the reactor or the upper and lower positions, rather than the center of the reactor. This results in the reactor being heated from the outside to the inside during specific heating, with a slow heating rate and uneven temperature distribution. Even if there is a structure in the prior art that heats from the center of the reactor, the design of its technical structure is usually not reasonable, the structure is not stable enough, and the task of center heating cannot be completed smoothly.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a central heating reactor with fast heating and reasonable structure. Summary of the invention

[0007] The purpose of the present invention is to provide a central heating reactor to address the deficiencies of the prior art. The technical solution is as follows:

[0008] A central heating reactor comprises a reactor body, the upper end of which is correspondingly provided with a driving motor, the main shaft of which extends downward into the reactor body, and a rotating plate is correspondingly provided at the shaft end of the main shaft, the rotating plate is horizontally placed and located at the upper end of the reactor body, and the lower end surface of the rotating plate is also provided with a central rotating cylinder extending downward, the cylinder wall of which is provided with a reticular structure, the liquid in the reactor body can correspondingly enter the central rotating cylinder, and the lower end of the reactor body is also provided with a rotating assembly, the lower end of which is correspondingly provided with the rotating assembly, and the driving motor can correspondingly drive the internal central rotating cylinder to rotate;

[0009] A plurality of groups of stirring rods are installed on the outer wall of the central rotating cylinder. The stirring rods stir in the reactor body as the central rotating cylinder rotates. A mounting frame is also provided in the central rotating cylinder. The lower end of the mounting frame is fixed to the lower end of the reactor body, and the upper end of the mounting frame is suspended. A heating element is installed on the mounting frame. The heating element heats the liquid in the central rotating cylinder, and then drives the stirring rods through the rotation of the central rotating cylinder to evenly dissipate the heat in the reactor body.

[0010] Furthermore, a liquid inlet pipe is arranged on the left side of the upper end of the reactor body, and a liquid outlet pipe is arranged on the right side of the lower end.

[0011] Furthermore, the rotating assembly comprises an annular mounting block arranged at the lower end of the reactor body, an annular groove is correspondingly arranged in the annular mounting block, and a supporting ball is correspondingly arranged in the annular groove;

[0012] The lower end of the central rotating cylinder is correspondingly placed in the annular groove, and the central rotating cylinder is correspondingly supported by the supporting balls in the annular groove, and the central rotating cylinder rotates accordingly.

[0013] Furthermore, there are five groups of heating elements on the mounting frame that are evenly spaced up and down, and a power supply device is also provided outside the reactor body. The power cord on the power supply device extends from the lower end of the reactor body into the central rotating cylinder to provide power to the heating elements.

[0014] Furthermore, a rotating paddle is provided on the inner wall of the central rotating cylinder, and the rotating paddle is installed correspondingly between two adjacent heating elements above and below. When the central rotating cylinder rotates, the rotating paddle inside is driven to rotate accordingly, thereby dissipating the internal heat to the outside.

[0015] Furthermore, the rotating paddles are provided in four groups evenly spaced apart from top to bottom, and each group is provided with four rotating paddles evenly spaced apart from top to bottom.

[0016] Furthermore, the stirring rods are evenly spaced apart in six groups, and each group is evenly spaced apart in six rod bodies.

[0017] Beneficial effects: The present invention has the following beneficial effects:

[0018] 1) In this device, the main shaft is driven to rotate by turning on the driving motor at the upper end, and the main shaft drives the overall central rotating cylinder to rotate accordingly. The central rotating cylinder rotates with the driving motor under the support of the rotating assembly at the lower end, and the stirring rod on the outer wall of the corresponding central rotating cylinder also rotates accordingly to stir the liquid inside the reactor body, thereby realizing the stirring of the liquid inside the reactor, and correspondingly realizing the stirring function inside the reactor;

[0019] 2) In this device, the heating element is arranged at the middle position of the central rotating cylinder. When the central rotating cylinder rotates, the internal heating element is heated at the same time. Since the heating element is correspondingly installed through the mounting frame, the mounting frame is arranged inside the central rotating cylinder, and the bottom of the mounting frame is fixed on the lower end of the reactor body, the mounting frame and the heating element on the mounting frame are separated from the central rotating cylinder. When the central rotating cylinder rotates and stirs, it will not affect the heating work of the internal heating element, nor will it affect the mounting frame. Therefore, the function of heating from the center position of the reactor can be realized;

[0020] 3) After the heating element in the device is heated in the central rotating cylinder, the central rotating cylinder drives the stirring rod to rotate, and the heat in the middle position is dissipated to the outside of the central rotating cylinder, so as to achieve the purpose of heating from the center of the reactor body and then smoothly dissipating the heat to all parts of the reactor body, so that the heating temperature rises quickly, the heat inside the reactor is uniform, and the structural setting is ingenious and reasonable;

[0021] 4) The device specifically sets the structure of the rotating assembly, which is specifically set as the structure of the annular mounting block. An annular groove is set on the annular mounting block, and a supporting ball is placed in the annular groove. Then, the lower end of the central rotating cylinder can be embedded and installed in the annular groove and supported by the supporting ball. After the driving motor is turned on, the central rotating cylinder rotates under the support of the supporting ball. The structural design is reasonable;

[0022] 5) The device has detailed arrangements for the mounting frame and the installation form of the heating elements in the central rotating cylinder. The heating elements are evenly installed from top to bottom, and a certain space is left between the adjacent heating elements in the upper and lower directions. Therefore, the device also has a rotating dial plate on the inner wall of the central rotating cylinder. The rotating dial plate is located between the upper and lower heating elements. When the central rotating cylinder rotates, the rotating dial plate on the inside will be driven to rotate accordingly, thereby accelerating the heat dissipation of the heating element at the center. The heat will be dissipated more smoothly by the rotating dial plate, and the structural arrangement is very reasonable and ingenious. BRIEF DESCRIPTION OF THE DRAWINGS
