Description

Technical Field

[0001] This utility model belongs to the field of temperature measurement equipment, specifically relating to a micro-channel temperature measurement device. Background Technology

[0002] In numerous scenarios requiring temperature measurement, especially for specific samples or measurement environments, traditional thermometers present several limitations. For instance, in the medical field, when measuring the temperature of deep tissues, conventional thermometers struggle to accurately penetrate and measure. In industrial applications, when measuring the temperature of confined spaces or highly viscous materials, ordinary thermometers cannot effectively contact the measurement site or are easily obstructed by materials, affecting measurement accuracy. Currently common thermometers, such as glass mercury thermometers, are inconvenient to read, and electronic thermometers have limited probe shapes and adaptability, failing to adequately meet these complex and diverse measurement needs.

[0003] In microchannel reactions, it is often necessary to measure the temperature of the fluid in the channel, but there is currently no simple and universal equipment for temperature measurement. Summary of the Invention

[0004] This invention provides a microchannel temperature measuring device for measuring temperature in a tubular reactor. The device is easy to operate and has minimal impact on the reaction process.

[0005] The technical solution of this utility model is as follows:

[0006] A microchannel temperature measuring device includes: a horizontal connecting pipe for connecting to a pipeline reactor and a syringe-shaped temperature measuring sleeve communicating with the horizontal connecting pipe, wherein the syringe-shaped temperature measuring sleeve and the horizontal connecting pipe form a T-shaped structure.

[0007] The syringe-shaped temperature measuring sleeve includes an outer tube, a piston rod that is hollow inside the outer tube, and a thermometer that passes through the piston rod.

[0008] The horizontal connecting pipe is equipped with a first valve, and the syringe-shaped temperature measuring sleeve is equipped with a second valve.

[0009] Preferably, the syringe-shaped temperature measuring sleeve is connected to a buffer branch pipe, and the buffer branch pipe is equipped with a buffer valve.

[0010] Preferably, the horizontal connecting pipe has threads on both sides that connect to the micro-channel to be measured.

[0011] Preferably, the outer tube of the syringe-shaped temperature measuring sleeve is made of a transparent material to facilitate better observation of the internal condition.

[0012] Preferably, the top of the piston rod is provided with an internal thread;

[0013] The outer surface of the thermometer is provided with an external thread that mates with the internal thread.

[0014] Compared with the prior art, the beneficial effects of this utility model are reflected in:

[0015] The micro-channel temperature measuring device of this invention can be used for temperature measurement in a pipeline reactor. During measurement, the flow direction and temperature of the liquid in the pipeline are controlled by adjusting the opening and closing of the first valve and the second valve, without interfering with the reaction in the reactor pipeline.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Depend on Figures 1-5 It can be seen that this micro-channel temperature measuring device mainly consists of a horizontal connecting pipe 3, a syringe-shaped temperature measuring sleeve and a buffer branch pipe 4. The syringe-shaped temperature measuring sleeve includes an outer tube 2, a piston rod 1 in a hollow state in the outer tube, and a thermometer (omitted in the figure) inserted in the piston rod 1.

[0023] The outer tube is made of high-strength, high-temperature resistant plastic, which ensures both structural strength and good chemical stability, while also allowing clear observation of the liquid level inside the syringe. It can adapt to various measurement environments and is not easily damaged.

[0024] The thermometer is located in the piston rod 1. The thermometer is made of stainless steel and has a threaded structure. It is connected to the piston rod 1 through the thread, which can control the extension and retraction of the thermometer. It can quickly and accurately sense the temperature of the liquid being measured and can achieve good sealing performance.

[0025] The piston rod 1 is slidably connected to the outer tube 2. By pushing the piston rod 1, the liquid in the syringe can be discharged. The outer surface of the piston rod 1 has anti-slip textures to facilitate the user's application of force.

[0026] The buffer branch pipe 4 is located on the side of the outer pipe 2 and has a buffer valve 6 on it to control whether it is connected to the outside. The buffer branch pipe 4 can be connected to a buffer bottle. When measuring temperature, rotating the buffer valve 6 connects the buffer branch pipe 4 to the external buffer bottle. If the fluid pressure in the pipeline is too high, when the piston push rod 1 is pushed above the buffer branch pipe, the fluid will flow out from the buffer branch pipe 4, which can prevent the piston push rod 1 from being pushed out of the outer pipe due to excessive pressure and causing danger.

[0027] The horizontal connecting pipe is equipped with a first valve 5, and the syringe-shaped temperature measuring sleeve is equipped with a second valve 7. By controlling the first valve 5 and the second valve 7, the flow path of the fluid in the valve body can be optimized and the fluid resistance can be reduced.

[0028] The horizontal connecting pipe has threads on both sides for connecting to the micro-channel to be measured. The connection to the micro-channel is achieved through these threads, and the micro-channel can be connected using conventional pipe fittings.

[0029] according to Figures 3-5 The exploded view clearly shows the internal structure of the first valve 5, the buffer valve 6, and the second valve 7. The first valve 5 and the second valve 7 have ball-shaped valve cores inside, which are easier to rotate and adjust, and facilitate fluid movement. The buffer valve can be a regular valve.

[0030] During the reaction of this invention, the first valve 5 is in the open state and the second valve 7 is in the closed state. When temperature detection is required, the operating valve stem is slowly rotated to move the valve core to the connected position, opening the second valve 7 and simultaneously opening the buffer valve on the syringe. This allows the liquid to be tested to enter the syringe. Once the liquid has accumulated to a measurable volume, the thermometer is rotated to submerge it below the liquid surface, ensuring the thermometer bulb is in full contact with the liquid, thus measuring the temperature of the liquid.

[0031] After temperature measurement is complete and the liquid in the syringe needs to be drained, keep the first valve 5 and the second valve 7 open, close the buffer valve on the syringe, rotate the thermometer to retract the sensing bulb into the piston, and press down the push rod to drain the liquid in the syringe into the horizontal pipe. Finally, slowly rotate the second valve 7 to move the valve core to the closed position, allowing the reaction to proceed as normal.
