Description

Technical Field

[0001] The utility model relates to the field of temperature detection equipment, in particular to a vibration-resistant integrated temperature transmitter. Background Technique

[0002] China's energy resource endowment is characterized by "rich coal, poor oil, and little gas", which leads to the need to adjust and optimize the energy structure in China's industrial development. At present, the domestic ethylene chemical production continues to increase, but still cannot meet the demand of the downstream market. Coal has always been the absolute main energy source of China's energy supply, accounting for about 70% of the total energy consumption. How to efficiently utilize coal resources and reduce carbon emissions has become an important task in the development of clean coal resources. How to improve the reaction efficiency of methanol to olefins and improve product quality, the core lies in the improvement of its process technology. The most critical core technology of this process technology lies in the catalytic cracking reactor, and the core of the reactor lies in the quality of the catalyst. Therefore, the quality of the catalyst directly affects the quality of olefin products, and it is very crucial to control the production quality of the catalyst;

[0003] The molecular sieve crystallization reactor is a key equipment in the key process of catalyst production. The stable control of the upper and lower temperatures in the crystallization reactant directly affects the quality and production capacity of the molecular sieve. Traditionally, ordinary thermal resistors are used to monitor and control the temperature in the reactor. Its working principle is to measure the temperature by using the change law of the resistance of platinum resistance materials with temperature. However, traditional ordinary thermal resistors have the following disadvantages and cannot be used for measuring the temperature of the crystallization reactor;

[0004] To ensure the quality and production capacity of the molecular sieve, the stirring frequency of the stirring paddle in the crystallization reactor is 60HZ, and the stirring diameter is 1 meter, which causes the internal medium to flow at a high speed, causing a strong impact on the thermometer sleeve of the thermal resistor, thereby causing high-frequency vibration of the thermal resistor thermometer, resulting in the end of the armored thermal resistor always colliding with the thermal resistor sleeve, resulting in the failure of the thermal resistor to measure temperature. Since traditional ordinary thermal resistors have no vibration-resistant device, according to the usage situation, the basic service life of the product is basically within 1 week, which cannot meet the requirement of long-term temperature measurement stability;

[0005] Traditional ordinary thermal resistors output RTD resistance signals. Since the temperature monitoring point is usually more than 200 meters away from the control room, the lead resistance is superimposed on the RTD resistance signal, thereby affecting the measurement accuracy of the product and unable to meet the requirement of temperature measurement accuracy;

[0006] The temperature measurement instrument product of the crystallization reactor adopts a flange connection structure. To ensure the sealing performance, the armored coupling material of the traditional ordinary thermal resistor is directly welded to the flange for sealing. Due to the thin wall thickness of the armored coupling material and less welding filler, the weld strength is low, and the welded part is easily damaged under the working condition of high-frequency vibration, unable to meet the requirement of product structure reliability. Content of the Utility Model

[0007] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a vibration-resistant integrated temperature transmitter, which is used to solve the technical problem that traditional ordinary thermal resistors in the prior art have no vibration-resistant device.

[0008] To achieve the above purpose and other related purposes, the present utility model provides a vibration-resistant integrated temperature transmitter, including:

[0011] A support rod, one end of the support rod is connected to the armored thermal resistance temperature measuring element, and the other end of the support rod is provided with a connecting flange;

[0012] Vibration damping mechanisms are further provided on both sides of the armored thermal resistance temperature measuring element, and an integrated display head is also installed on the connecting flange.

[0013] The advantage of adopting the above technical solution is that by setting the vibration damping mechanism, the armored thermal resistance temperature measuring element is prevented from colliding with the thermal resistance sleeve all the time, effectively reducing the high-frequency vibration of the thermal resistance thermometer and meeting the requirements of long-term temperature measurement stability.

[0014] Optionally, the vibration damping mechanism includes an elastic member, and the maximum outer diameter of the elastic member is greater than the outer diameter of the armored thermal resistance temperature measuring element.

[0015] Optionally, the vibration damping mechanism further includes a plurality of annular baffles, the annular baffles are respectively located on the axial two sides of the elastic member, the annular baffles are arranged on the support rod, and the annular baffles are used to limit the elastic member.

[0016] Optionally, the elastic member is a spring.

[0017] Optionally, the elastic member is a tower-shaped spring.

[0018] Optionally, a reinforcing sleeve is provided at the connection between the connecting flange and the support rod, and the reinforcing sleeve is used to strengthen the weld strength.

[0019] Optionally, a connecting pipe is further provided on the connecting flange, and the integrated display head is inserted into the connecting pipe.

[0020] Optionally, the inner wall of the connecting pipe is provided with threads, and the integrated display head is threadedly connected to the connecting pipe.

[0021] As described above, a vibration-resistant integrated temperature transmitter of the present utility model has the following beneficial effects: By providing a vibration damping mechanism, it is possible to prevent the armored thermal resistance temperature measuring element from constantly colliding with the thermal resistance sleeve, effectively reducing the high-frequency vibration of the thermal resistance thermometer and meeting the requirements for long-term stability of temperature measurement.

[0036] Please refer to Figure 1 As shown, the present utility model provides a vibration-resistant integrated temperature transmitter, including:

[0037] A temperature sensing block 1;

[0038] An armored thermal resistance temperature measuring element 2, and the temperature sensing block 1 is connected to the armored thermal resistance temperature measuring element 2;

[0039] A support rod 4, one end of the support rod 4 is connected to the armored thermal resistance temperature measuring element 2, and a connecting flange 3 is provided at the other end of the support rod 4;

[0040] Vibration damping mechanisms 5 are further provided on both sides of the armored thermal resistance temperature measuring element 2, and an integrated display head 6 is further installed on the connecting flange 3.

[0041] It should also be noted that in this application, vibration damping mechanisms 5 are installed on both sides of the armored thermal resistance temperature measuring element 2 to prevent the armored thermal resistance temperature measuring element from continuously colliding with the thermal resistance sleeve, effectively reducing the high-frequency vibration of the thermal resistance thermometer and meeting the requirements for long-term temperature measurement stability.

[0042] Exemplarily, the vibration damping mechanism 5 includes an elastic member 501, and the maximum outer diameter of the elastic member 501 is greater than the outer diameter of the armored thermal resistance temperature measuring element 2.

[0043] It should also be noted that the vibration damping mechanism 5 uses an elastic member 501 to reduce the collision and wear between the armored thermal resistance temperature measuring element 2 and the inner diameter of the thermal resistance sleeve caused by high-frequency vibration by using elasticity.

[0044] Exemplarily, the shock absorption mechanism 5 further includes a plurality of annular baffles 502, the annular baffles 502 are respectively located on both axial sides of the elastic member 501, the annular baffles 502 are arranged on the support rod 4, and the annular baffles 502 are used to limit the elastic member 501.

[0045] It should also be noted that the purpose of setting the annular baffle 502 is to limit the elastic member 501 and prevent the elastic member 501 from axially displacing along the support rod 4.

[0046] Exemplarily, the elastic member 501 is a spring.

[0047] It should also be noted that in this solution, the elastic member 501 is a spring. One end of the spring can be directly fixed on the support rod 4, and the other end is used to contact the inner wall of the thermal resistance sleeve to reduce collision and friction.

[0048] Exemplarily, the elastic member 501 is a conical spring.

[0049] It should also be noted that for the conical spring of the elastic member 501, the outer diameter of the middle part is larger than that of both ends. During installation, the middle part of the elastic member 501 collides with the inner wall of the thermal resistance sleeve, reducing the collision and wear between the armored thermal resistance temperature measuring element 2 and the inner diameter of the thermal resistance sleeve caused by high-frequency vibration, and improving the stability performance of the product.

[0050] Exemplarily, a reinforcing sleeve 7 is provided at the connection between the connecting flange 3 and the support rod 4, and the reinforcing sleeve 7 is used to strengthen the weld strength.

[0051] It should also be noted that by setting the reinforcing sleeve 7, welding filler can be increased during welding, solving the problem that when the ordinary thermal resistance armored couple material is directly welded to the flange for sealing, due to the thin wall thickness of the armored couple material and less welding filler, the weld strength is low, and improving the safety performance of the product.

[0052] Exemplarily, a connecting pipe 8 is further provided on the connecting flange 3, and the integrated display head 6 is inserted into the connecting pipe 8.

[0053] It should also be noted that in this application, the connecting pipe 8 is threadedly connected to the integrated display head 6 to ensure the stability of the connection between the two.

[0054] Exemplarily, the inner wall of the connecting pipe 8 is provided with threads, and the integrated display head 6 is threadedly connected to the connecting pipe 8.

[0055] It should also be noted that by setting the threads, when installing the integrated display head 6, it can be installed through the threads, effectively improving the stability of the connection.

[0056] In summary, for the vibration-resistant integrated temperature transmitter of the present utility model, by providing the vibration damping mechanism 5, the armored thermoresistance temperature measuring element is prevented from continuously colliding with the thermoresistance sleeve, effectively reducing the high-frequency vibration of the thermoresistance thermometer and meeting the requirements of long-term stability of temperature measurement.
