Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically a temperature-controlled reaction vessel. Background Technology
[0002] To improve reaction efficiency during material processing, the internal stability of the reactor can be enhanced. According to patent application publication number CN109772250A, a novel temperature-controlled reactor is provided. This invention includes a reactor body, a stirring shaft, and heating tubes parallel to the stirring shaft on both sides. Heating resistance wires are wound around the heating tubes. Fixed sleeves are arranged parallel to the stirring shaft, and the heating tubes are fixed between the fixed sleeves. A liquid level pipe is connected to the upper side wall of the reactor body, and a branch pipe is provided between the reactor body and the liquid level pipe. Temperature gauges are installed below the liquid level pipe and on the branch pipe. The heating resistance wires and temperature gauges are electrically connected to a temperature controller. The heating tubes are located inside the reactor body, directly heating the liquid inside, resulting in faster heating.
[0003] However, in existing reactor technologies, the temperature is increased by directly heating the reactor body using electric heating tubes. But when low-temperature heating is required, the heating tubes raise the temperature quickly and to a high temperature, making low-temperature heating difficult to control. This can easily lead to excessive heat causing material deterioration, and the reactor lid can also cause excessive heat loss during heating, affecting heating efficiency. Therefore, improvements to the existing technology are needed. Utility Model Content
[0004] The purpose of this invention is to provide a temperature-controlled reactor that solves the problem of inconvenient temperature control when heating the reactor body at low temperatures.

[0006] Preferably, the water suction pipe is fixedly connected to the heating cover, and the return pipe is fixedly connected to the output end of the circulation pump. The circulation pump can draw water out of the heating cover through the water suction pipe and then inject it back into the heating cover through the return pipe, so that the water inside the heating cover circulates.
[0007] Preferably, the two heat insulation covers are in contact with each other, and the heat insulation covers are in sliding contact with the stirring motor, so that the heat insulation covers can keep the lid of the vessel warm.
[0008] Preferably, the upper ends of both heat insulation covers are fixedly connected to a fixing cover, and the interior of the two fixing covers is slidably connected to a U-shaped frame, which can limit the two heat insulation covers through the fixing cover.
[0009] Preferably, the sealing mechanism includes a sealing ring, and a sealing ring is fixedly connected to the middle of the inner wall of the drain pipe. Two symmetrically distributed connecting rods are slidably connected inside the sealing ring. A pressure bar is fixedly connected to the upper end of the connecting rod, a sealing disc is fixedly connected to the lower end of the pressure bar, a support bar is fixedly connected to the lower end of the connecting rod, and a spring is provided on the outer side of the connecting rod. The pressure bar can apply downward pressure to the sealing disc.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model incorporates an electric heating element, a reflux pipe, and a circulation pump inside the heating hood. When low-temperature heating of the reactor body is required, the water inside the heating hood is preheated by the electric heating element, and then the reactor body is heated at a low temperature by the water. At the same time, the circulation pump can circulate the water inside the heating hood, which can make the entire reactor body heat more evenly. This allows for convenient control of the low-temperature heating temperature. Furthermore, when high-temperature heating is required, the water inside the heating hood can be drained through the drain pipe, making the reactor more convenient to use.
[0014] 2. This utility model adds a heat insulation cover, a fixing cover and a U-shaped frame to the heating cover. After the raw materials are added to the inside of the kettle, the kettle lid can be sealed and kept warm by the heat insulation cover. This can effectively prevent excessive heat loss and improve heating efficiency while avoiding resource waste. Attached Figure Description

[0022] Please see Figure 1 , Figure 2 , Figure 4The suction pipe 8 is fixedly connected to the heating cover 2, and the return pipe 4 is fixedly connected to the output end of the circulation pump 7. The circulation pump 7 can draw water out of the heating cover 2 through the suction pipe 8 and then inject it back into the heating cover 2 through the return pipe 4, so that the water inside the heating cover 2 circulates. The two heat insulation covers 9 are in contact with each other and slide in contact with the stirring motor 12. The heat insulation covers 9 can keep the lid 10 warm. The upper ends of the two heat insulation covers 9 are fixedly connected to the fixing covers 14. The interior of the two fixing covers 14 is slidably connected to a U-shaped frame 15. The U-shaped frame 15 can limit the two heat insulation covers 9 through the fixing covers 14.
[0023] Please see Figure 1 , Figure 3 The sealing mechanism 6 includes a sealing ring 61. The sealing ring 61 is fixedly connected to the middle of the inner wall of the drain pipe 5. Two symmetrically distributed connecting rods 62 are slidably connected inside the sealing ring 61. A lower pressure strip 63 is fixedly connected to the upper end of the connecting rod 62. A sealing disc 64 is fixedly connected to the lower end of the lower pressure strip 63. A support strip 65 is fixedly connected to the lower end of the connecting rod 62. A spring 66 is provided on the outside of the connecting rod 62. The lower pressure strip 63 can apply downward pressure to the sealing disc 64. One end of the spring 66 is fixedly connected to the support strip 65. The other end of the spring 66 is fixedly connected to the sealing ring 61. The spring 66 can drive the support strip 65 for support through its elastic force. The sealing disc 64 is slidably connected to the sealing ring 61. Both the lower pressure strip 63 and the support strip 65 are slidably connected to the inner wall of the drain pipe 5. The sealing disc 64 can move the sealing ring 61.
[0024] The specific implementation process of this utility model is as follows: When in use, after the raw materials are added into the interior of the kettle body 1 through the feeding cover 11, the two heat preservation covers 9 are flipped and reset, and then the U-shaped frame 15 is inserted into the interior of the two fixed covers 14 at the same time. After the insertion is completed, the kettle lid 10 can be kept warm by the heat preservation cover 9 through the limiting position of the heat preservation cover 9.
[0025] The heating element 3 is activated to heat the water inside the heating hood 2. Simultaneously, the circulation pump 7 is activated, which draws water out of the heating hood 2 through the suction pipe 8 and then re-injects it into the heating hood 2 through the return pipe 4, thus circulating the water inside the heating hood 2. This allows for more uniform heating of the vessel body 1 by the heating hood 2 and facilitates control of the heating temperature of the vessel body 1. When high-temperature heating is required, the support bar 65 is pushed. The support bar 65 moves the sealing disc 64 below the pressure bar 63 via the connecting rod 62, compressing the spring 66. When the sealing disc 64 disengages from the sealing ring 61, the seal on the inside of the sealing ring 61 is released, allowing the water inside the heating hood 2 to be discharged. After the water is discharged, the vessel body 1 can be heated at high temperature by the heating element 3.
