Description

Technical Field

[0001] This utility model relates to the field of heating vessel technology, specifically a spiral tube heating vessel. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation.

[0003] The existing Chinese utility model patent with publication number CN207187719U discloses an electric heating kettle, including a stirring container made of magnetic material, a stirring rack on the stirring container, a stirrer extending into the stirring container on the stirring rack, an induction heating component on the inner wall of the stirring container for inductively heating the stirrer or the material, and a temperature measuring component on the inner wall of the stirring container for detecting the temperature of the material and feeding it back to the induction heating component. The stirring container holds the material, and the stirrer stirs the material inside the stirring container. At this time, the induction heating component heats the stirrer to heat the material. The heat from the stirrer is absorbed by the material, improving the heating efficiency of the induction heating component. When the induction heating component directly heats the material, the heat power is directly absorbed by the material, increasing the heating speed and making it convenient and practical. The temperature measuring component allows the induction heating component to control its heating power to prevent the material temperature from becoming too high.

[0004] However, the existing spiral tube heating vessel has poor heating effect during use, and the spiral tube spirals downwards, so the liquid inside the lower half of the tube is at a lower temperature after heat exchange in the upper half, thus affecting the heat exchange effect.

[0016] Compared with the prior art, the present invention provides a spiral tube heating vessel, which has the following beneficial effects:

[0017] This invention allows liquid to be added to the interior of the spiral tube body via an inlet pipe and discharged after heat exchange via an outlet pipe. Liquid can be transported via a connecting pipe on one side of the connecting block in the middle of the spiral tube body. A temperature detector on one side of the connecting pipe can monitor the temperature. When the temperature is higher than a specified temperature, the liquid is returned to the interior of the spiral tube body via the connecting pipe. When the temperature is too low, it is discharged through the drain port at the bottom of the control valve. Simultaneously, a pump draws high-temperature liquid through a pumping pipe into the merging valve. The merging valve then sends the high-temperature liquid into the interior of the spiral tube body for heat exchange, improving the heat exchange effect of the spiral tube heating vessel. This also avoids the problem of uneven heating temperatures on the upper and lower sides of the reactor affecting the heating effect, thus enhancing the practicality of the spiral tube heating vessel.

[0026] Please see Figure 1 - Figure 4 In this embodiment, a spiral tube heating vessel includes: a reaction vessel 1, a connecting ring 11 fixedly installed on the top of the reaction vessel 1, a heat insulation layer 12 fixedly installed on the outside of the reaction vessel 1, a shell 13 fixedly installed on the outside of the heat insulation layer 12, a support plate 14 fixedly installed on one side of the shell 13, a bottom ring 15 fixedly installed on the bottom of the shell 13, and four bases 16 fixedly installed around the bottom of the bottom ring 15.

[0027] Specifically, the bottom of the spiral tube heating vessel can be supported by the four bases 16 at the bottom of the bottom ring 15, the outside of the reactor 1 can be wrapped and insulated by the insulation layer 12, and the outside of the insulation layer 12 can be wrapped by the outer shell 13.

[0028] A spiral tube body 2 is fixedly installed on the outside of the reactor 1. An inlet pipe 21 is fixedly installed on one side of the top of the spiral tube body 2. An outlet pipe 22 is fixedly installed on one side of the bottom of the spiral tube body 2. Two connecting blocks 23 are fixedly installed on one side of the middle of the spiral tube body 2. A connecting pipe 24 is fixedly installed on one side of the connecting block 23. The connecting pipe 24 is in the shape of a "U". A temperature detector 25 is fixedly installed on the right side of the middle of the connecting pipe 24. A control valve 26 is fixedly installed in the middle of the connecting pipe 24. A drain port 27 is fixedly installed at the bottom of the control valve 26. A merging valve 28 is fixedly installed on the left side of the middle of the connecting pipe 24. A pump 29 is fixedly installed on one side of the merging valve 28. A pump pipe 210 is fixedly installed on one side of the pump 29.

[0029] Specifically, liquid enters through inlet pipe 21 and exits through outlet pipe 22. Temperature detector 25 can detect the temperature inside connecting pipe 24, and control valve 26 can control the liquid inside connecting pipe 24 to be discharged from outlet 27.

[0030] A top cover 3 is movably connected to the top of the connecting ring 11. A drive motor 31 is fixedly installed in the middle of the top of the top cover 3. A rotating rod 32 is fixedly installed in the middle of the bottom of the drive motor 31. Two support rods 33 are fixedly installed on the upper and lower sides of the middle of the rotating rod 32. A scraper 34 is fixedly installed on one side of the support rod 33. A stirring rod 35 is fixedly installed in the middle of the rotating rod 32.

[0031] Specifically, the operation of the drive motor 31 can drive the rotating rod 32 to rotate, and the rotation of the rotating rod 32 can drive the support rod 33 to rotate, so that the scraper 34 can fit into the inside of the reactor 1, thereby avoiding the problem of liquid adsorbing on the inner wall of the reactor 1 and affecting the heating effect.

[0032] In use, the spiral tube heating vessel is first placed in the designated position and supported by the bottom ring 15 at the bottom of the reactor 1. The four bases 16 at the bottom of the bottom ring 15 also support the spiral tube heating vessel. The heat exchange liquid is introduced into the spiral tube body 2 through the inlet pipe 21, heating the reactor 1 through the spiral tube body 2. The heat-exchanged liquid is discharged through the outlet pipe 22. A connecting pipe 24 connects the two connecting blocks 23, thus connecting the upper and lower spiral tube bodies 2. A temperature detector 25 monitors the temperature inside the connecting pipe 24. When the temperature is higher than a specified temperature, the liquid is returned to the spiral tube body 2 through the connecting pipe 24. When the temperature is too low, the liquid is discharged through the drain port 27 by the operation of the intermediate control valve 26 in the connecting pipe 24. Simultaneously, the operation of the liquid pump 29 allows high-temperature liquid to be drawn into the interior of the merging valve 28 through the liquid extraction pipe 210, thereby sending the high-temperature liquid into the interior of the spiral tube body 2 below for heat exchange. This improves the practicality and heat exchange effect of the spiral tube heating vessel, avoiding the problem of uneven temperatures at the top and bottom of the reactor 1 affecting the heating effect. The operation of the drive motor 31 drives the rotating rod 32 to rotate, and the support rod 33 supports the scraper 34. The rotation of the rotating rod 32 causes the scraper 34 to rotate against the inner wall of the reactor 1, thus hanging on the inner wall of the reactor 1. This avoids the problem of liquid adhering to the inner wall of the reactor 1 and affecting the heat exchange effect. The stirring rod 35 stirs and mixes the liquid inside the reactor 1, improving the practicality and convenience of the spiral tube heating vessel.
