Description

Technical Field

[0001] This utility model relates to a temperature detection device based on the valve core of the bottom valve of a reaction vessel, belonging to the technical field of pharmaceutical and chemical production equipment. Background Technology

[0002] In pharmaceutical and chemical production, the reactor is a core piece of equipment, and the reaction of materials inside is significantly affected by temperature. Traditional reactors often have temperature monitoring devices installed on the side or top of the main body, but temperature measurements at these locations often fail to accurately reflect the true temperature of the bottom space of the reactor. Especially in some special reactions, there may be temperature differences in the bottom material due to uneven stirring, uneven heat distribution, etc. The temperature near the bottom valve is crucial to the safety of the material discharge process and the accuracy of subsequent process connections. If the material temperature in the bottom valve area is abnormal but cannot be detected in a timely and accurate manner, it can easily lead to risks such as changes in material properties, pipeline blockage, or even safety accidents. Utility Model Content

[0003] To address the problem of insufficient material temperature monitoring in the bottom valve area of ​​existing reactors, this invention provides a temperature detection device based on the valve core of the bottom valve of a reactor.

[0004] The technical solution of this utility model is as follows: A temperature detection device based on the valve core of a reactor bottom valve includes a reactor bottom valve and a thermocouple. The screw of the reactor bottom valve has a channel, and the thermocouple is inserted into the channel. The probe of the thermocouple is close to the inner end of the screw, and the temperature display dial of the thermocouple is located at the outer end of the screw. The temperature display dial of the thermocouple is used to display the temperature detected by the probe of the thermocouple.

[0005] In one preferred embodiment of this utility model, the channel is a blind hole channel, the opening of which is located at the outer end of the screw. After the thermocouple is inserted into the blind hole channel, the probe of the thermocouple is located inside the blind hole channel and close to the inner end of the screw.

[0006] Furthermore, the blind hole channel extends along the axis of the screw.

[0007] As another preferred embodiment of this utility model, the channel is a through channel that passes through the screw along the axis of the screw. After the thermocouple is inserted into the through channel, the probe of the thermocouple extends out from the inner end of the screw, and the probe of the thermocouple is sealed to the screw by a sealing kit.

[0008] Furthermore, the sealing kit includes a sealing ring and a sealing gasket. The sealing ring is fitted onto the probe of the thermocouple and fixedly connected to the inner end of the screw by multiple screws. The sealing gasket is disposed between the sealing ring and the inner end of the screw.

[0009] As a preferred embodiment of this invention, the thermocouple is fixedly connected to the outer end of the screw by a thermocouple fixing bolt.

[0010] The advantages of this utility model are: (1) Improve monitoring accuracy; make up for the blind spot of traditional reactor temperature monitoring in the bottom valve area, accurately obtain the real-time temperature of this key position, provide more comprehensive data support for process control, and optimize reaction condition control.

[0011] (2) Enhance safety; It can detect sudden temperature changes in the bottom valve area caused by local overheating of materials, abnormal exothermic reaction, etc., and take measures in advance to prevent material decomposition, deterioration, blockage of pipelines, and potential safety accidents such as leakage and fire, and ensure production continuity.

[0012] (3) Facilitates on-site operation; the material temperature can be displayed intuitively on-site, so that operators do not need to enter the control room to view remote data. They can quickly obtain material temperature information when inspecting or operating the bottom valve on-site, thereby improving the convenience of operation and the efficiency of emergency response.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Example 1

[0017] like Figure 1As shown, this embodiment discloses a temperature detection device based on the valve core of a reactor bottom valve, including a reactor bottom valve 1 and a thermocouple 2. A blind hole channel 4 is provided on the screw 3 of the reactor bottom valve 1. The blind hole channel 4 extends along the axis of the screw 3, and the opening of the blind hole channel 4 is located at the outer end of the screw 3. The thermocouple 2 is inserted into the blind hole channel 4, and the probe 5 of the thermocouple 2 is located inside the blind hole channel 4 and close to the inner end of the screw 3. The temperature display dial 6 of the thermocouple 2 is located at the outer end of the screw 3 and is used to display the temperature detected by the probe 5 of the thermocouple 2. The thermocouple 2 is fixedly connected to the outer end of the screw 3 by a thermocouple fixing bolt 7.

[0018] Example 2

[0019] like Figure 2 and Figure 3 As shown, this embodiment discloses a temperature detection device based on the valve core of a reactor bottom valve, including a reactor bottom valve 1 and a thermocouple 2. A through channel 8 is provided on the screw 3 of the reactor bottom valve 1, and the through channel 8 passes through the screw 3 along the axis of the screw 3. The thermocouple 2 is inserted into the through channel 8, and the probe 5 of the thermocouple 2 extends from the inner end of the screw 3. The probe 5 of the thermocouple 2 and the screw 3 are sealed by a sealing kit. The sealing kit seals the gap between the probe 5 of the thermocouple 2 and the screw 3. The sealing kit includes a sealing ring 9 and a sealing gasket 10. The sealing ring 9 is sleeved on the probe 5 of the thermocouple 2 and fixedly connected to the inner end of the screw 3 by multiple screws. The sealing gasket 10 is disposed between the sealing ring 9 and the inner end of the screw 3. The temperature display dial 6 of the thermocouple 2 is located at the outer end of the screw 3 and is used to display the temperature detected by the probe 5 of the thermocouple 2. The thermocouple 2 and the outer end of the screw 3 are fixedly connected by thermocouple fixing bolts 7.

[0020] This invention involves machining a channel on the screw 3 of the bottom valve 1 of the reactor, and fixing a local thermometer, i.e., a thermocouple 2, inside the channel. The probe 5 of the thermocouple 2 extends into the interior of the bottom valve 1 near the material, so as to directly contact the material or be within the effective range of the material's thermal radiation, and accurately measure the temperature of the material near the bottom valve 1. At the same time, the thermocouple 2 is equipped with a clear local temperature display dial 6, which allows operators to directly read temperature data around the equipment without relying on a remote monitoring system, and can grasp the temperature changes of the material in the area of ​​the bottom valve 1 of the reactor in the first instance.

[0021] When this utility model is implemented: (1) Component selection: Select thermocouples with appropriate materials and ranges according to the properties of the materials in the reactor (such as corrosivity, temperature range, etc.). For example, for strong acid and alkaline material environments, use corrosion-resistant stainless steel or enamel thermocouple probes.

[0022] (2) Installation operation: First, process a suitable channel on the bottom valve body, then firmly install the thermocouple, ensuring that the thermocouple probe is accurately inserted into the bottom valve according to the design depth, and at the same time, perform sealing treatment to prevent material leakage; after installation, calibrate the thermocouple to ensure the accuracy of its measurement data.

[0023] (3) Daily use and maintenance: During the operation of the reactor, the operator regularly checks the temperature readings detected by the thermocouples on-site and compares them with the temperature data of the remote monitoring system. If any abnormal deviation is found, the thermocouple fault or calibration problem should be investigated in time. At the same time, the thermocouples should be cleaned and calibrated regularly according to the established maintenance plan, and aging parts should be replaced to ensure their long-term stable operation.

[0024] This invention provides a simple, practical, and effective temperature monitoring optimization solution for pharmaceutical and chemical production by adding a local thermometer to the bottom valve of the reactor, and has high application value.
