Description

Technical Field

[0001] The utility model belongs to the technical field related to reactors, and particularly relates to a constant temperature reactor capable of feedback adjustment. Background Art

[0002] Reactor is a kind of equipment used for chemical reactions, physical and chemical processes and laboratory research. It is usually made of steel plates of a certain thickness, with high corrosion resistance and high temperature and high pressure bearing capacity. It is widely used in pharmaceutical, chemical, food processing and other fields to meet the needs of different processes. According to different process requirements, it can be divided into atmospheric pressure reactor, high pressure reactor, vacuum reactor and other types, but the reactor still has the following disadvantages in actual use:

[0003] 1. When the reactor is working, it is usually hollow inside and outside. When water passes through, the constant temperature in the reactor can be adjusted by adjusting the water temperature. When the constant temperature in the reactor is in effect, the transported reaction temperature water is easy to generate heat radiation outside the reactor, causing energy loss. When working, it is easy to cause slight deviations in the reaction temperature, affecting the adequacy of the reaction;

[0004] 2. When the reactor is working, temperature measurement is directly adopted. During the temperature adjustment process of the reactor, it is manually controlled. During the control process, measurement and control are required, which is cumbersome to operate and inconvenient to use. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-5 The utility model is a constant temperature reactor with feedback adjustment, comprising a heat preservation sleeve 1, an outer fixing ring 2, a closed top cover 3 and a through pipe 4. The interior of the heat preservation sleeve 1 is hollow. The heat preservation sleeve 1 reduces the heat loss between the inner receiving chamber 203 and the inner wall of the heat preservation sleeve 1 through the hollow interior. An outer fixing ring 2 is fixed on the inner wall of the upper part of the heat preservation sleeve 1. The outer fixing ring 2 fixes the closed top cover 3 thereon through the inner fixing ring 301. A closed top cover 3 is arranged above the outer fixing ring 2. The closed top cover 3 closes the top end of the inner fixing ring 301, so that the top end of the inner receiving chamber 203 is closed. A through pipe 4 is fixed through the closed top cover 3. The through pipe 4 leads out the power connection line of the thermal switch 402. The bottom end of the through pipe 4 is provided with a thermal switch 402. The start and stop of the water equipment for externally conveying the temperature required by the reactor is controlled by the thermal switch 402.

[0026] Specifically, an inner receiving chamber 203 is fixed at the bottom end of the outer fixed ring 2, and a water pipe 201 is vertically passed through the outer fixed ring 2 on one side of the inner receiving chamber 203, and the top of the water pipe 201 is connected to the output end of the external constant temperature water delivery equipment. A water outlet pipe 202 is passed through and fixed at a position symmetrical to the water pipe 201 in the outer fixed ring 2, and the top of the water outlet pipe 202 is connected to the input end of the external constant temperature water delivery equipment. The outer fixed ring 2 contains the reaction materials therein through the inner receiving chamber 203, and transports water of the required temperature of the reactor to between the inner receiving chamber 203 and the insulation sleeve 1 through the water pipe 201, so that the inner receiving chamber 203 and the materials therein are at a suitable temperature, and outputs water back to the external constant temperature water delivery equipment through the water outlet pipe 202.

[0027] Furthermore, a silver coating 101 is fixed on the hollow surface of the insulation sleeve 1, and the inner receiving cavity 203 is arranged in the insulation sleeve 1, and the inner receiving cavity 203 does not contact the inner wall of the insulation sleeve 1. The insulation sleeve 1 reduces the internal energy loss of heat radiation generated thereon through the silver coating 101 therein.

[0028] The operation process of this embodiment is as follows: during operation, when the temperature in the reactor is not high enough, the thermal switch 402 turns on the external constant temperature water delivery device, and delivers water of the required temperature of the reactor to between the inner receiving chamber 203 and the insulation sleeve 1 through the water delivery pipe 201, so that the inner receiving chamber 203 and the materials therein are at a suitable temperature, and outputs water back to the external constant temperature water delivery device through the water outlet pipe 202 until the inner receiving chamber 203 and the materials therein are raised to a suitable temperature. When water passes through the insulation sleeve 1, the insulation sleeve 1 passes through its internal hollowness, and the silver-plated layers 101 therein cooperate with each other to reduce the internal energy loss of heat radiation generated thereon.

[0030] See also Figure 1 , 3 , 4, 5, on the basis of the specific embodiment 1, an inner fixing ring 301 is provided at the bottom end of the closed top cover 3, and the inner fixing ring 301 is fixed in the outer fixing ring 2, and a closing sleeve 303 is fixed at the bottom end of the closed top cover 3, and the closing sleeve 303 is sleeved in the outer fixing ring 2, and is fixed in the outer fixing ring 2 by the inner fixing ring 301, so as to provide an installation position for the closed top cover 3, and the gap between the closed top cover 3 and the inner fixing ring 301 is closed by the closing sleeve 303.

[0031] Specifically, the closed top cover 3 is provided with mounting bolts 302 in a circular array, and all mounting bolts 302 are threadedly connected to the inner fixing ring 301. The closed top cover 3 is inserted therein through the mounting bolts 302 and then screwed into the inner fixing ring 301, so that the closed top cover 3 seals the top end of the inner fixing ring 301, and is opened after the work is completed to provide the function of taking out the reactants in the reactor.

[0032] Furthermore, a through hole 304 is opened in the center of the closed top cover 3, the through pipe 4 is fixed in the through hole 304, the bottom end of the through pipe 4 is fixedly connected with a connecting screw barrel 401, the top end of the thermal switch 402 is threadedly connected in the connecting screw barrel 401, the closed top cover 3 fixes the through pipe 4 through the through hole 304, and the thermal switch 402 is threadedly connected thereto through the connecting screw barrel 401.

[0033] The operation process of this embodiment is as follows: when working, determine the working state of the thermal switch 402 (after power on, observe whether the external device for delivering constant temperature water is working). When the thermal switch 402 is damaged, unscrew the mounting bolts 302 on the closed top cover 3, and then remove the closed top cover 3. After removing the closed top cover 3, unscrew the thermal switch 402 in the connecting screw barrel 401. After replacement, reset the closed top cover 3 and start working. When working, when the temperature of the material in the inner receiving chamber 203 drops, start the thermal switch 402, so that the external device for delivering constant temperature water delivers water to the water delivery pipe 201. After the material reaches a suitable reaction temperature, the thermistor is turned off, and the external device for delivering constant temperature water stops working. The temperature of the material in the inner receiving chamber 203 is maintained through feedback regulation.
