Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, and in particular to a heat-insulating and heating reaction vessel. Background Technology
[0002] In the 1950s, my country's reactor industry began, mainly relying on imitation and import of foreign technologies for application in the chemical industry. At that time, the reactor technology was relatively backward, with limited product variety, small production scale, and limited research and application of heating technology. Heating methods were simple, temperature control accuracy was low, and energy utilization efficiency was not high. In the 1980s, with my country's economic development, the reactor industry gradually grew and began to independently research and produce reactors. In terms of heating technology, some improvements were made, such as the use of high-temperature heating element structures to improve heating efficiency and temperature uniformity. As we entered the 21st century, my country's reactor industry entered a period of rapid development, with the market size continuously expanding. In the field of heated reactors, technological innovations emerged continuously. The use of heat transfer oil for heating settings, through which heat transfer oil circulates between the heating furnace and the reactor, transfers heat to the materials inside the reactor. Heat transfer oil heating has the advantages of high heating temperature and good stability.
[0003] However, the applicant discovered that the existing technology still has shortcomings. In some reaction processes with high temperature control requirements, it is necessary to further improve the temperature control of the heating reactor. Currently, the temperature control of the reactor is only achieved by continuously increasing the temperature of the heat transfer oil. Once the reactor overheats, it is easy for the reactor to run out of control, leading to fire or explosion accidents. In addition, the heat transfer oil has a large expansion coefficient. In the case of excessive filling or excessive temperature, the expansion of the heat transfer oil can easily cause the injection port or jacket to crack, resulting in leakage and fire. Moreover, the heat transfer process is long, the temperature adjustment sensitivity is low, and the temperature control accuracy is reduced, making it difficult to meet the needs of some reactions with high temperature control accuracy requirements, and the heating is uneven.

[0004] To address the above problems, this utility model provides a heat-insulating and heating reactor. By improving the heat-conducting pipe, the heat-insulating contact area between the heat-conducting pipe and the reactor body can be adjusted, effectively improving the reaction requirements for temperature control precision, ensuring uniform heating of the reactor, and increasing the effective heating area.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A heat-insulating and heating reaction vessel includes a vessel body and a heat conduction device;
[0007] The interior of the vessel is a cavity used for storing materials;
[0008] The heat-conducting device is coaxially spirally wound around the outside of the vessel body, and the heat-conducting device includes a heat-conducting pipe;
[0009] The heat-conducting pipe includes a first pipe and a second pipe. The first pipe is concentrically installed inside the second pipe. The heat-conducting pipe and the vessel body have an adjustable heat-insulating contact area, depending on the direction of the hot oil flow.

The transmission spindle is mounted on the central axis of the frame, and one end of the transmission spindle is connected to the output end of the reducer.
[0013] As an improvement, the accessory device includes a feed inlet 1, a feed inlet 2, an exhaust port, a sampling port, a safety valve, a thermometer port, a pressure gauge port, a hand hole, and a sight glass;

[0033] Example 1:
[0034] like Figures 1 to 5 As shown, a heat-insulating and heating reaction vessel includes a vessel body 1 and a heat-conducting device 2;
[0035] The interior of the vessel body 1 is a cavity used for storing materials;
[0036] The heat-conducting device 2 is coaxially spirally wound around the outside of the vessel body 1, and the heat-conducting device 2 includes a heat-conducting pipe 21;
[0037] The heat-conducting pipe 21 includes a first pipe 211 and a second pipe 212. The first pipe 211 is concentrically installed inside the second pipe 212. The heat-conducting pipe 21 and the vessel body 1 are adjustable according to the pipe to which the hot oil flows.
[0038] The vessel body 1 includes an upper cover 11, a cylindrical body 12, and a base 13. The upper cover 11 and the cylindrical body 12 are connected by a flange 10, and the cylindrical body 12 is welded to the base 13.
[0039] The upper cover 11 is also provided with a transmission device 14 and an accessory device 15. The transmission device 14 is installed on the upper part of the top end cap of the upper cover 11, and the accessory device 15 is installed on the cover surface of the upper cover 11.
[0040] The transmission device 14 includes a motor 141, a reducer 142, a frame 143, and a transmission spindle 144. The bottom of the motor 141 is connected to the top of the reducer 142 via a vertical flange 145. The bottom of the reducer 142 is attached to the top of the frame 143 and fixedly connected by screws. The transmission spindle 144 is mounted on the central axis of the frame 143, and one end of the transmission spindle 144 is connected to the output end of the reducer 142.
[0041] The accessory device 15 includes a first feed inlet 151, a second feed inlet 152, an exhaust port 153, a sampling port 154, a safety valve 155, a thermometer port 156, a pressure gauge port 157, a hand hole 158, and a sight glass 159.
[0042] The safety valve 155 is used to ensure the safe operation of the reactor, and the thermometer port 156 and pressure gauge port 157 are used to monitor the temperature and pressure parameters inside the reactor.
[0043] The cylindrical body 12 also includes a stirring shaft 121, a coupling 122, a frame stirrer 123, and a vessel base 124. One end of the stirring shaft 121 is connected to the other end of the transmission main shaft 144 through the coupling 122. The coupling 122 is used for connection and fixation, and to protect the stirring shaft and the transmission device.
[0044] The frame stirrer 123 is fixedly connected to the stirring shaft 121 by screws, and the vessel base 124 is fixedly connected to the other end of the stirring shaft 121 by screws.
[0045] The base 13 includes a discharge port 131 and a plurality of mounting brackets 132. The mounting brackets 132 are used for stable support. The discharge port 131 is positioned opposite to the center opening of the stirring shaft 121. The vessel base 124 is welded and fixed inside the base 13.
[0046] It should be noted that the working principle of the transmission device 14 is as follows: after the motor 141 is reduced in speed by the reducer 142, it drives the transmission main shaft 144 and the stirring shaft 121 to rotate. The frame stirrer 123 is driven to rotate by the rotation of the stirring shaft 121. The stirring shaft 121 and the transmission main shaft 144 are securely connected by the coupling 122.
[0047] The heat conduction device 2 also includes an oil inlet 22, an oil outlet 23, and a valve 24. The oil inlet 22 is located at the upper part of the heat conduction pipe 21, and the oil outlet 23 is located at the lower part of the heat conduction pipe 21. The oil inlet 22 and the oil outlet 23 are arranged opposite to each other. The valve 24 is installed at the oil inlet 22 and is used to control the opening and closing state of the oil inlet 22.
[0048] The heat-conducting pipe 21 is also provided with a third pipe 213, which is arranged in parallel and around the second pipe 212. After the hot oil is transferred into the heat-conducting pipe 21 through the oil inlet 22, the direction of the hot oil flow is controlled by adjusting the position of the valve 24, thereby further increasing the heat-conducting pipe 21 and the vessel body 1 in terms of heat insulation contact area.
[0049] It should be noted that the heat pipe operates at an adjustable temperature. When the material preparation requires low-temperature heat preservation, the valve 24 on the oil inlet 22 is opened to the first position, and hot oil is input through the oil inlet 22 into the first pipe 211 to perform low-temperature heat preservation for the vessel body 1. When the material preparation requires medium-temperature heat preservation, the valve 24 is opened to the second position, and hot oil is simultaneously input through the oil inlet 22 into the first pipe 211 and the second pipe 212 to further increase the contact area and perform medium-temperature heat preservation for the vessel body 1. When the material preparation requires high-temperature heat preservation, the valve 24 is opened to the third position, and hot oil is simultaneously input through the oil inlet 22 into the first pipe 211, the second pipe 212, and the third pipe 213 to further increase the contact area and perform high-temperature heat preservation for the vessel body 1.
[0050] Working principle: After the material enters the vessel through the feed inlet 151 and feed inlet 152 on the top cover 11, the transmission device 14 starts. The motor 141 in the transmission device 14 is reduced in speed by the reducer 142 and drives the transmission main shaft 144 and the stirring shaft 121 to rotate. The rotation of the stirring shaft 121 drives the frame agitator 123 to rotate and stir the material. At the same time, the hot oil in the oil storage tank begins to circulate. The hot oil is input into the heat conduction pipe 21 through the oil inlet 22 and then flows back from the oil outlet 23. The oil circulation system in the storage tank heats and maintains the temperature of the vessel body 1. According to the temperature requirements, the hot oil in the heat-conducting pipe 21 can be controlled by valve 24 to flow to the first pipe 211, the second pipe 212, and the third pipe 213 at three temperature levels. As more pipes are fed with hot oil, the heat-conducting pipe 21 and the vessel body 1 will have a larger heat contact area, thereby controlling the heat preservation and heating effect so that the material can be processed at a suitable temperature. Once the material has been processed at a suitable temperature, the discharge port 131 can be opened to discharge the material.
[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
