Description

Technical Field

[0001] This utility model relates to the field of industrial temperature measuring equipment technology, and in particular to a multifunctional temperature measuring instrument for a novel BDO high-pressure hydrogenation aluminum-nickel alloy catalyst. Background Technology

[0002] In the high-pressure hydrogenation process of BDO (1,4-butanediol), the activity and selectivity of the AlNi alloy catalyst are extremely sensitive to process temperature. Therefore, precise temperature monitoring of the catalyst or its vicinity using a multifunctional thermometer is crucial for ensuring stable reaction operation and product quality. These thermometers typically rely on thermocouple probes for contact temperature measurement and transmit the signal to the main unit via a transmission cable.

[0003] In complex industrial environments, thermocouple probes, as sensing components, may require frequent replacement due to prolonged use, physical wear, or the need for periodic calibration. This necessitates that the connection between the thermocouple probe (or its connected signal adapter) and the transmission cable be both robust and reliable, as well as easy to install and remove.

[0004] In existing technologies, the connection between signal adapters and transmission cables typically employs a threaded tightening structure or a pluggable aviation connector. Threaded connections are cumbersome, time-consuming, and labor-intensive when frequent probe changes are required, especially in complex field environments or when operators are wearing protective gloves. Furthermore, repeated tightening can easily lead to thread wear, resulting in poor contact or an unstable connection.

[0005] Traditional plug-in aviation connectors often have unreliable locking structures. In complex industrial environments, if the transmission cable is accidentally dragged or vibrated, the connector may loosen or fall off, causing signal interruption and severely affecting the continuity and reliability of temperature measurement data. This makes it impossible to meet the requirements for efficient and reliable replacement. Therefore, this invention proposes a multifunctional temperature measuring instrument for a new type of BDO high-pressure hydrogenation aluminum-nickel alloy catalyst to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multifunctional temperature measuring instrument for novel BDO high-pressure hydrogenation aluminum-nickel alloy catalysts, aiming to improve the problem of cumbersome probe and cable connection operation in some existing multifunctional temperature measuring instruments for novel BDO high-pressure hydrogenation aluminum-nickel alloy catalysts.

[0007] This utility model provides a multifunctional temperature measuring instrument for a novel BDO high-pressure hydrogenation aluminum-nickel alloy catalyst, including a main unit, a transmission cable, a signal adapter, and a thermocouple probe; the main unit is electrically connected to the signal adapter via the transmission cable, and the signal adapter is connected to the thermocouple probe.

[0008] The multi-functional thermometer is also equipped with a replacement mechanism, which is located between the connection end of the signal adapter and the connection end of the transmission cable to enable quick plugging and unplugging and reliable locking of the two.

[0009] The replacement mechanism includes a pin, a connecting ring, a sliding ring, a spring, and a retaining ball. The pin is fixedly connected to the signal adapter, serving as an insertion part on one side of the signal adapter; the connecting ring is fixedly connected to the transmission cable, serving as a docking base on one side of the transmission cable; the sliding ring is slidably disposed on the outer periphery of the connecting ring, serving as an operating part for locking and releasing; the spring is wrapped around the connecting ring and located on one side of the sliding ring, providing elastic force for the sliding ring to automatically reset; the retaining ball is embedded in the wall of the connecting ring, serving as a locking element for locking the pin.

[0010] In the combined state, the sliding ring has an internal protrusion structure. When locked, the internal protrusion actively squeezes the retaining bead under the elastic force of the spring three. The squeezed retaining bead then locks into and secures the groove of the pin, thereby achieving a firm lock between the pin and the connecting ring and ensuring the reliability of signal transmission.

[0011] Preferably, a fixing component is installed on the back of the main unit. The fixing component is used to store and clamp the thermocouple probe when the temperature measuring instrument is not in use, so as to prevent the probe from being damaged due to careless placement.

[0012] Preferably, the fixing component includes a base, a first jaw clamp, and a second jaw clamp. The base is fixedly connected to the back of the main unit, serving as the mounting base for the fixing component; both the first jaw clamp and the second jaw clamp are rotatably mounted on the base, and together they form a jaw structure for clamping the thermocouple probe.

[0013] Preferably, the fixing assembly further includes spring one and spring two. Spring one and spring two are used to provide a continuous elastic restoring force, which automatically pushes jaw one and jaw two together to achieve automatic clamping of the probe.

[0014] Preferably, as a specific connection method, one end of the spring is fixedly connected to the jaw clamp, and the other end of the spring is fixedly connected to the base, thereby applying a reset torque to the jaw clamp.

[0015] Preferably, in conjunction with spring one, one end of spring two is fixedly connected to jaw clamp two, and the other end of spring two is fixedly connected to the base, together realizing the clamping force driven by both sides, ensuring the stability of clamping.

[0016] Preferably, a display screen is installed on the outside of the main unit. The display screen is used to present temperature data from multiple measuring points in real time, providing operators with an intuitive data reading interface for easy on-site monitoring.

[0017] Preferably, an operation panel is also installed on the outside of the main unit. The operation panel integrates multiple buttons or touch areas for advanced functions such as parameter setting, measurement point switching, and data query, thereby improving the interactivity of the thermometer.

[0018] Preferably, the signal adapter has a built-in conversion circuit that converts the raw millivolt signal generated by the thermocouple probe into a standard signal with stronger anti-interference capability. The standard signal is then reliably transmitted to the host computer for analysis and display via a transmission cable.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problems of cumbersome connection and inconvenient replacement of thermocouple probes and transmission cables in the prior art by setting a replacement mechanism including a pin, a connecting ring, a sliding ring, a spring and a retaining ball. The sliding ring releases the retaining ball from locking the pin when pulled by an external force, thus achieving the technical effect of convenient operation, quick replacement and reliable connection.

[0021] 2. This utility model solves the problem in the prior art that the thermocouple probe is not properly stored, which is caused by the lack of a dedicated storage structure in the thermometer. This results in the thermocouple probe being arbitrarily suspended, easily shaken or damaged when not in use. The invention achieves the technical effect of simple structure, convenient storage and effective protection of the probe.

[0022] 3. This utility model solves the problems of traditional temperature measuring instruments having limited functions, unintuitive data display, and difficult parameter setting by integrating a display screen and operation panel on the host and using a signal converter to convert thermocouple signals into standard signals. It achieves the technical effects of multi-functional integration, user-friendly human-computer interaction, intuitive data observation, and convenient parameter setting and data query.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Reference Figures 1 to 3 This utility model provides a multifunctional temperature measuring instrument for a novel BDO high-pressure hydrogenation aluminum-nickel alloy catalyst, which aims to solve the problems of cumbersome thermocouple probe replacement, insufficient connection reliability, and easy damage to the probe due to the lack of a dedicated storage structure when not in use in the prior art.

[0034] like Figure 1 As shown, a multifunctional temperature measuring instrument for a novel BDO high-pressure hydrogenation aluminum-nickel alloy catalyst includes a main unit 1, a transmission cable 4, a signal converter 6, and a thermocouple probe 7. The main unit 1 is electrically connected to the signal converter 6 via the transmission cable 4, and the signal converter 6 is connected to the thermocouple probe 7.

[0035] like Figure 1 and Figure 3As shown, a replacement mechanism 5 is provided between the connection end of the signal adapter 6 and the connection end of the transmission cable 4. The replacement mechanism 5 enables quick insertion and removal of the signal adapter 6 and the transmission cable 4. The replacement mechanism 5 includes a pin 52, a connecting ring 53, a sliding ring 51, a spring 54, and a retaining ball 55. The pin 52 is fixedly connected to the signal adapter 6, the connecting ring 53 is fixedly connected to the transmission cable 4, the sliding ring 51 is slidably disposed on the outer periphery of the connecting ring 53, and the spring 54 is sleeved around the connecting ring 53. The upper part is located on one side of the sliding ring 51. The retaining bead 55 is embedded in the wall of the connecting ring 53. The sliding ring 51 has an internal protrusion. When locked, the internal protrusion presses the retaining bead 55, so that the retaining bead 55 is locked in the groove of the pin 52, thereby achieving a firm connection. When separation is required, the sliding ring 51 is pulled to overcome the elastic force of the spring 3 54. The internal protrusion of the sliding ring 51 is released from the pressure on the retaining bead 55. The retaining bead 55 retracts under the external force when the pin is pulled out, so that the pin 52 can be pulled out smoothly.

[0036] Reference Figure 1 and Figure 2 The main unit 1 of the multi-functional thermometer has a fixing component 8 installed on its back. The fixing component 8 is used to store and hold the thermocouple probe 7 after use. The fixing component 8 includes a base 81, a first claw 83 and a second claw 84. The base 81 is fixedly connected to the back of the main unit 1. The first claw 83 and the second claw 84 are rotatably mounted on the base 81. The fixing component 8 also includes a first spring 82 and a second spring 85. The first spring 82 and the second spring 85 are used to provide elastic restoring force to push the first claw 83 and the second claw 84 closer together. Specifically, one end of the first spring 82 is fixedly connected to the first claw 83, and the other end of the first spring 82 is fixedly connected to the base 81. One end of the second spring 85 is fixedly connected to the second claw 84, and the other end of the second spring 85 is fixedly connected to the base 81. The elastic restoring force generated by the combined action of the first spring 82 and the second spring 85 pushes the first claw 83 and the second claw 84 to firmly clamp the thermocouple probe 7.

[0037] Reference Figure 1 The host 1 is equipped with a display screen 2, which is used to display temperature data of multiple measuring points in real time. The host 1 is also equipped with an operation panel 3, which is used for parameter setting, measuring point switching and data query. The signal converter 6 is used to convert the millivolt signal of the thermocouple probe 7 into a standard signal and transmit the standard signal to the host 1 for processing and display through the transmission cable 4.

[0038] The implementation principle of this application embodiment is as follows: When measurement is required, the operator holds the host 1 and contacts the thermocouple probe 7 with the object to be measured. The millivolt signal generated by the thermocouple probe 7 is transmitted to the signal converter 6. The signal converter 6 converts the millivolt signal into a standard signal. The converted standard signal is transmitted to the host 1 through the transmission cable 4. The processing circuit inside the host 1 processes the signal and sends the temperature data to the display screen 2 for real-time display. The operator can set parameters, switch measurement points, and query data through the operation panel 3.

[0039] When it is necessary to replace the thermocouple probe 7 or the signal adapter 6, the operator pulls the sliding ring 51 of the replacement mechanism 5. The sliding ring 51 slides on the outer periphery of the connecting ring 53 and squeezes the spring 3 54. As the sliding ring 51 moves, its internal protrusions release the pressure on the retaining bead 55. Under the external force when the pin is pulled out, the retaining bead 55 no longer locks the groove position of the pin 52. At this time, the pin 52 and the signal adapter 6 fixedly connected to it can be pulled out from the connecting ring 53, thereby achieving quick separation from the transmission cable 4. During installation, the operation is reversed. The pin 52 is pushed in to drive the retaining bead 55 until the sliding ring 51 presses the retaining bead 55 again under the restoring force of the spring 3 54.

[0040] After the measurement is completed, when it is necessary to store the thermocouple probe 7, the operator presses the thermocouple probe 7 between the first jaw 83 and the second jaw 84 of the fixing component 8. Since the first spring 82 is fixedly connected between the first jaw 83 and the base 81, and the second spring 85 is fixedly connected between the second jaw 84 and the base 81, the first spring 82 and the second spring 85 always provide elastic restoring force. The restoring force pushes the first jaw 83 and the second jaw 84 to move closer to each other and automatically clamps the thermocouple probe 7 firmly, thereby fixing it to the back of the main unit 1 and preventing it from shaking or being damaged.
