Description

Technical Field

[0001] This application relates to the technical field of smoke and dust collection, and in particular to a smoke and dust sampling tube. Background Technology

[0002] Smoke and dust generated during industrial production are major pollutants causing air pollution. To mitigate air pollution, it is necessary to understand and control industrial emissions, which requires the use of smoke and dust samplers. Smoke and dust samplers can collect and analyze data such as smoke concentration, humidity, excess air coefficient, and flow velocity. The smoke and dust sampling tube is the core component of the sampler, directly affecting the accuracy of the sampler's detection results.

[0003] A utility model patent with Chinese patent authorization announcement number CN218823445U discloses a dust sampling tube, comprising a sampler body, an extension tube disposed inside the sampler body, a telescopic tube fixedly connected to the extension tube and the sampler body, a second connecting tube fixedly connected to one side of the extension tube, a sampling head disposed on one side of the extension tube, a first connecting tube fixedly connected to one side of the sampling head, a filter tube disposed between the sampling head and the extension tube, a gas flow rate sensor installed inside the sampler body, and a collection tank installed at the top of the gas flow rate sensor. This dust sampling tube adjusts the sampling length by pulling the extension tube. The sealing ring and rubber sleeve on the outside of the extension tube increase the friction of movement, thereby achieving stability in adjustment. The extension tube does not extend or retract during sampling. This structure, through the adjustable extension tube, improves the sampling flexibility of the sampler body and solves the problem of inconvenient adjustment of the sampling tube size.

[0004] The solution also has the following problems: the device removes the filter screen by installing a slide on the filter tube, but the filter screen still needs to be manually slid by the staff to complete the removal. However, this method cannot remove the filter screen quickly and will also cause the staff to come into direct contact with pollutants or harmful substances that may be present on the filter screen, increasing the safety hazard.

[0005] Therefore, in order to solve the above problems, this application provides a dust sampling tube. Utility Model Content

[0006] To address the issue of quickly disassembling the filter while avoiding direct contact between workers and the filter, this application provides a dust sampling tube.

[0007] This application provides a dust sampling tube, including a sampler body. Two sampling tube bodies are provided on one side of the sampler body, and a filter tube is threadedly connected between the two sampling tube bodies. Four sliding grooves are provided on both sides of the filter tube. An installation frame one is fixedly installed between the sliders on one side, and a filter screen one is provided in the installation frame one. An installation frame two is fixedly installed between the sliders on the other side, and a filter screen two is provided in the installation frame two. Magnetic columns are fixedly installed in two of the opposite sliding grooves, and magnetic blocks are fixedly installed on the side of two opposite sliders near the magnetic columns. The magnetic blocks are magnetically connected to the magnetic columns.

[0008] Preferably, a compression elastic element is fixedly installed on one side of each of the other two slides, and a rubber pad is fixedly installed on one end of each of the multiple compression elastic elements, with each of the two rubber pads contacting one side of the other two sliders.

[0009] Preferably, each of the plurality of sliders is fixedly mounted with a push rod on the side away from the compression spring, and one end of the push rod is in contact with the side wall of the sampling tube body.

[0010] Preferably, a gas flow rate sensor is installed on the left side of the front of the sampling tube body, a temperature sensor is installed on the right side of the front of the sampling tube body, and a sampling head is connected to the side of the sampling tube body near the filter tube.

[0011] Preferably, a telescopic tube is provided on one side of the sampler body, the telescopic tube is slidably engaged with the sampling tube body, a locking mechanism is provided inside the telescopic tube, and the bottom of the sampler body is fixedly installed.

[0012] In summary, this application includes the following beneficial technical effects: by setting magnetic pillars and magnetic blocks, the slider and the inside of the slide groove can be connected, thereby locking the first and second mounting frames and filtering the inhaled smoke and dust. By setting compression elastic elements and rubber pads, workers can disassemble the first and second filters. Pressing the push rod will cause the force of the compression elastic element to pop out the first and second mounting frames, releasing the magnetic connection between the magnetic pillars and magnetic blocks. This reduces workers' direct contact with the first and second filters, which may contain pollutants or harmful substances, and reduces the safety hazards caused by direct contact.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A dust sampling tube, as referenced Figure 1 - Figure 4 The sampler includes a sampler body 1. Two sampling tube bodies 3 are located on one side of the sampler body 1. A filter tube 4 is threaded between the two sampling tube bodies 3. Four sliding grooves 9 are provided on both sides of the filter tube 4, arranged in a rectangular pattern. A mounting frame 15 is fixedly installed between the sliders 10 on one side, containing a filter screen 16. A mounting frame 2 12 is fixedly installed between the sliders 10 on the other side, containing a filter screen 2 13. The mesh size of the filter screen 2 13 is smaller than that of the filter screen 16. Magnetic pillars 11 are fixedly installed in two of the corresponding sliding grooves 9, and magnetic blocks 14 are fixedly installed on the side of two of the corresponding sliders 10 closest to the magnetic pillars 11. The magnetic block 14 is magnetically connected to the magnetic column 11. By setting the magnetic column 11 and the magnetic block 14, the slider 10 can be connected to the inside of the slide groove 9, thereby locking the first mounting frame 15 and the second mounting frame 12 and filtering the inhaled smoke and dust. By setting the compression elastic element 18 and the rubber pad 19, the operator can disassemble the first filter screen 16 and the second filter screen 13. Pressing the push rod 17 will cause the force of the compression elastic element 18 to pop out the mounting frame and the second mounting frame 12, releasing the magnetic connection between the magnetic column 11 and the magnetic block 14. This reduces the operator's direct contact with the first filter screen 16 and the second filter screen 13, which may contain pollutants or harmful substances, and reduces the safety hazards caused by direct contact.

[0021] Reference Figure 1 - Figure 4On one side of the other two slides 9, compression elastic elements 18 are fixedly installed. Rubber pads 19 are fixedly installed on one end of each of the compression elastic elements 18. Both rubber pads 19 are in contact with one side of the other two sliders 10. The compression rebound force of the four symmetrical compression elastic elements 18 is greater than the magnetic force between the magnet 14 and the magnetic column 11, which can pop out the first mounting frame 15 and the second mounting frame 12, thereby releasing the locking of the first mounting frame 15 and the second mounting frame 12.

[0022] Reference Figure 1 - Figure 4 Each of the multiple sliders 10 has a push rod 17 fixedly installed on the side away from the compression spring. One end of the push rod 17 is in contact with the side wall of the sampling tube body 3, which can limit the slider 10 and the compression elastic element 18.

[0023] Reference Figure 1 - Figure 4 A gas flow rate sensor 6 is installed on the left side of the front of the sampling tube body 3, and a temperature sensor 7 is installed on the right side of the front of the sampling tube body 3. A sampling head 5 is connected to the side of the sampling tube body 3 near the filter tube 4. The gas flow rate sensor 6 measures the flow rate of the smoke and dust, and the temperature sensor 7 measures the temperature of the smoke and dust.

[0024] Reference Figure 1 - Figure 4 A telescopic tube 2 is provided on one side of the sampler body 1. The telescopic tube 2 slides with the sample tube body 3. A locking mechanism is provided inside the telescopic tube 2. A handle 8 is fixedly installed at the bottom of the sampler body 1, which can extend and retract the sample tube body 3, adjust the length of the sample tube body 3, and limit the position of the sample tube body 3 after adjustment.

[0025] Working principle: During use, the handle 8 can be held by hand, and the distance between the telescopic tube 2 and the sampling tube body 3 can be adjusted according to the sampling needs. After adjustment, the locking mechanism locks the sampling tube body 3. Smoke and dust can enter the sampling tube body 3 through the sampling head 5. Then, the flow rate of the smoke and dust is measured by the gas flow rate sensor 6, and the temperature of the smoke and dust is measured by the temperature sensor 7. The smoke and dust are filtered through filter screen 16 and filter screen 13. The filtered impurities accumulate in filter screen 16 and filter screen 13. When replacing filter screen 16 and filter screen 13, the two ends can be rotated. Take out the sampling tube body 3 and filter tube 4. Then press the push rods 17 at both ends. The push rods 17 drive the mounting frame 15 and mounting frame 2 12 to move inward. Since the compression rebound force of the compression elastic element 18 is greater than the magnetic force between the magnetic block 14 and the magnetic column 11, the force of the compression elastic element 18 can make the mounting frame and mounting frame 2 12 pop out, releasing the magnetic connection between the magnetic column 11 and the magnetic block 14. Then pull the two pull rods to pull the mounting frame 15 and mounting frame 2 12 out of the filter tube 4, and replace or clean the filter screen 16 and filter screen 2 13.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
