Description

Technical Field

[0001] This utility model relates to the field of sampling probe technology, specifically a tar removal sampling probe. Background Technology

[0002] During the production, transportation and processing of coal gas, it is necessary to conduct real-time sampling and monitoring of the coal gas composition to ensure production safety and product quality. In addition to the tar sampling probe as the core sampling equipment, it is necessary to extract sample gas from coal gas containing impurities such as tar, benzene, naphthalene, dust and moisture, and at the same time achieve the separation of tar from the sample gas.

[0003] Traditional sampling probes have significant drawbacks in use. Tar in coal gas tends to condense and adhere to the surface of sampling pipelines and filter components. Long-term accumulation can cause pipeline blockage, affecting the flow of sample gas and sampling efficiency. Tar adhesion can also reduce the purity of sample gas filtration, leading to deviations in subsequent component analysis results. Furthermore, blockages require frequent disassembly and maintenance, increasing operating costs and downtime. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a tar removal sampling probe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tar removal sampling probe, comprising a sampling probe body, a connecting mechanism at the bottom of the sampling probe body, and a cleaning mechanism surrounding the connecting mechanism;

[0006] The cleaning mechanism includes a protective frame, which is fixedly connected to the front of the sampling probe body. A miniature high-pressure air pump is fixedly connected inside the protective frame. A transmission tube is fixedly connected to the bottom of the miniature high-pressure air pump. A first connecting tube is fixedly connected to the inner side of the transmission tube. A separator plate is fixedly connected to the top of the outer periphery of the first connecting tube. A second connecting tube is provided at the bottom of the first connecting tube. A sealing cylinder is threadedly connected to the bottom of the second connecting tube. A sampling cylinder is fixedly connected to the bottom of the sealing cylinder. A filter cylinder is fixedly connected inside the sampling cylinder. A partition is fixedly connected to the inner side of the filter cylinder. A heating wire is fixedly connected to the outer periphery of the partition.

[0007] Preferably, the first connecting pipe is fixedly connected to the bottom of the sampling probe body, and the bottom of the first connecting pipe and the top of the second connecting pipe are in contact with each other. By using the first connecting pipe and the second connecting pipe together, the sampling probe body can sample the gas deep inside.

[0008] Preferably, the sampling cylinder has an inlet at the bottom, which allows the gas to enter the sampling cylinder and enables the sampling probe to sample and monitor the gas.

[0009] Preferably, the connecting mechanism includes a baffle plate, which is fixedly connected to the top periphery of the second connecting pipe. A connecting cylinder is rotatably connected to the periphery of the second connecting pipe, and an external threaded cylinder is fixedly connected to the top of the baffle plate.

[0010] Preferably, the connecting sleeve is threaded to the bottom periphery of the first connecting pipe, and the external threaded sleeve is threaded to the bottom inner side of the first connecting pipe. The use of the connecting sleeve and the external threaded sleeve together makes the connection between the first connecting pipe and the second connecting pipe tighter.

[0011] Preferably, the connecting cylinder is disposed around the periphery of the baffle plate, and the inner side of the connecting cylinder is in close contact with the periphery of the baffle plate. The baffle plate can limit the movement of the connecting cylinder, so that when the first connecting pipe moves after the connecting cylinder is connected to the first connecting pipe, the first connecting pipe is not easily moved away from the second connecting pipe.

[0012] Compared with the prior art, this utility model provides a tar removal sampling probe, which has the following beneficial effects:

[0013] 1. In the cleaning mechanism of this tar removal sampling probe, the sampling cylinder has a built-in filter to achieve efficient separation of tar and sample gas. With the synergistic effect of the baffle and heating wire, it can reduce tar condensation and adhesion, ensuring the purity of the sample. The miniature high-pressure gas pump delivers high-pressure gas through the transmission pipe, which can clean the pipeline and filter components of residual tar in time, effectively avoid blockage, and reduce the maintenance frequency.

[0014] 2. The tar removal sampling probe has a connection mechanism that uses a double threaded engagement between the connecting cylinder and the external threaded cylinder, combined with a baffle plate for limiting the connection, to ensure that the first connecting pipe and the second connecting pipe fit tightly together, thereby improving the connection sealing and structural stability and preventing sampling leakage.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1-4 The present invention provides a technical solution: a tar removal sampling probe, including a sampling probe body 1, a connecting mechanism 3 at the bottom of the sampling probe body 1, and a cleaning mechanism 2 around the connecting mechanism 3;

[0026] The cleaning mechanism 2 includes a protective frame 22, which is fixedly connected to the front of the sampling probe body 1. A miniature high-pressure air pump 21 is fixedly connected inside the protective frame 22. A transmission pipe 23 is fixedly connected to the bottom of the miniature high-pressure air pump 21. A first connecting pipe 201 is fixedly connected to the inner side of the transmission pipe 23. A separator plate 24 is fixedly connected to the top of the outer periphery of the first connecting pipe 201. A second connecting pipe 202 is provided at the bottom of the first connecting pipe 201. A sealing cylinder 26 is threadedly connected to the bottom of the second connecting pipe 202. A sampling cylinder 25 is fixedly connected to the bottom of the sealing cylinder 26. A filter cylinder 27 is fixedly connected inside the sampling cylinder 25. A partition 28 is fixedly connected to the inner side of the filter cylinder 27. A heating wire 29 is fixedly connected to the outer periphery of the partition 28.

[0027] Furthermore, the first connecting pipe 201 is fixedly connected to the bottom of the sampling probe body 1, and the bottom of the first connecting pipe 201 is in contact with the top of the second connecting pipe 202. Through the cooperation of the first connecting pipe 201 and the second connecting pipe 202, the sampling probe body 1 can sample the gas deep inside.

[0028] Furthermore, an inlet is provided at the bottom of the sampling cylinder 25, which allows coal gas to enter the sampling cylinder 25 and enables the sampling probe body 1 to sample and monitor the coal gas.

[0029] Example 2

[0030] Please see Figure 1-4 Furthermore, based on Embodiment 1, the connecting mechanism 3 includes a baffle plate 32, which is fixedly connected to the top periphery of the second connecting pipe 202. A connecting cylinder 33 is rotatably connected to the periphery of the second connecting pipe 202, and an external threaded cylinder 31 is fixedly connected to the top of the baffle plate 32.

[0031] Furthermore, the connecting sleeve 33 is threaded to the bottom periphery of the first connecting pipe 201, and the external threaded sleeve 31 is threaded to the bottom inner side of the first connecting pipe 201. Through the cooperation of the connecting sleeve 33 and the external threaded sleeve 31, the first connecting pipe 201 and the second connecting pipe 202 are connected more tightly.

[0032] Furthermore, the connecting cylinder 33 is disposed around the baffle plate 32, and the inner side of the connecting cylinder 33 is in close contact with the outer side of the baffle plate 32. The baffle plate 32 can limit the connecting cylinder 33, so that when the first connecting pipe 201 moves after the connecting cylinder 33 is connected to the first connecting pipe 201, the first connecting pipe 201 is not easy to move away from the second connecting pipe 202.

[0033] In actual operation, when this device is used, and when it is necessary to sample and monitor the gas inside the pipeline through the sampling probe body 1, the top of the second connecting pipe 202 is brought into contact with the bottom of the first connecting pipe 201. The second connecting pipe 202 is rotated so that the external threaded cylinder 31 at the top of the second connecting pipe 202 can be threadedly connected to the bottom of the inner side of the first connecting pipe 201. The connecting cylinder 33 is pulled upward so that it is threadedly connected to the bottom of the outer periphery of the first connecting pipe 201, so that the first connecting pipe 201 and the second connecting pipe 202 are tightly connected to each other. The sealing cylinder 26 is threadedly connected to the bottom of the outer periphery of the second connecting pipe 202. The sampling probe body 1 is installed on the outer periphery of the gas transmission pipe 23. The heating wire 29 is energized so that it can heat the inside of the sampling cylinder 25, so that the sampling cylinder 25 can filter the gas it draws in. The filter cylinder 27 can filter the tar in the gas. The heating wire 29 makes it difficult for the tar to solidify and adhere to the outer periphery of the filter cylinder 27, thus clogging the filter cylinder 27.

[0034] When the filter cartridge 27 needs to be cleaned, turn on the miniature high-pressure air pump 21 and use it in conjunction with the transmission pipe 23 to blow high-pressure gas into the first connecting pipe 201 and the second connecting pipe 202. This allows the high-pressure gas to be transmitted to the outside of the filter cartridge 27, blowing away and cleaning the tar adhering to the outside of the filter cartridge 27. This prevents the filter cartridge 27 from becoming clogged and improves the sampling effect of the sampling probe body 1.
