[0002] The main function of high-temperature explosion-proof filters is to filter gases or liquids in high-temperature environments, preventing explosive substances from entering the system and ensuring the safety of equipment and personnel. High-temperature explosion-proof filters effectively capture solid particles, droplets, and even tiny aerosols in the air through multiple mechanisms such as physical barrier, inertial impaction, diffusion deposition, gravity settling, and electrostatic adsorption, ensuring the purity of the output gas.
[0003] However, existing high-temperature explosion-proof filters still have the following problems during use:
[0004] Existing high-temperature explosion-proof filters require the connecting pipe to be clamped into a compression fitting during use. This results in poor stability between the connecting pipe and the compression fitting, and the pipe is easily separated under tension, affecting its performance. Therefore, it is necessary to develop a high-temperature explosion-proof filter for use in the existing filter field. Utility Model Content
[0005] To address the shortcomings of existing technologies, current high-temperature explosion-proof filters require the connecting pipe to be clamped onto a compression fitting during use. This results in poor stability between the connecting pipe and the compression fitting, and the pipe is easily separated under tension, affecting its performance. This invention proposes a high-temperature explosion-proof filter.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a high-temperature resistant explosion-proof filter, comprising:

[0012] Preferably, one end of the lower shell is provided with a slot, and the slot is provided with a first internal thread. The other end of the lower shell is provided with an assembly slot, which communicates with the first internal thread. The assembly slot is provided with a fixing slot, which is located outside the first internal thread.
[0013] Preferably, one end of the upper shell is provided with a second internal thread, and the other end of the upper shell is provided with a mounting groove.

[0017] This invention involves inserting a connecting pipe into a compression fitting, with one end of the connecting pipe close to a limiting pipe. Movable blocks are moved along guide rods, and under the action of an adjusting rod, the adjusting blocks move one end of the movable rod inside the mounting pipe. The adjusting blocks cause a clamping ring to hold one end of the connecting pipe on the limiting pipe. Simultaneously, the movable blocks move the connecting blocks closer together, and the extension rod on the connecting blocks causes the clamping ring to hold the surface of the connecting pipe. At this point, rotating an adjusting bolt on a fixed block causes one end of the adjusting bolt and the fixed block to clamp the movable block, fixing its position on the guide rod. This improves the stability between the connecting pipe and the compression fitting, facilitating later use. Attached Figure Description

The limiting tube 8 is fixedly fitted with the joint sealing ring 2. One end of the limiting tube 8 is fixedly fitted with a ferrule connector 1. The ferrule connector 1 is located on one side of the lower shell 3 and the upper shell 7. The ferrule connector 1, the limiting tube 8 and the threaded tube 9 are hollow inside, and the hollow parts are respectively connected to the first internal thread port 12 and the second internal thread port 15.
[0030] In this utility model, the lower shell 3 and the upper shell 7 are threaded together. Under the action of the shell sealing ring 6, the assembly groove 13 is sealed. The threaded tubes 9 on the two ferrule connectors 1 are respectively threaded into the first internal thread port 12 and the second internal thread port 15 until the limiting tube 8 is fixed to the connector sealing ring 2. At this time, the flow sealing is improved.
[0031] Reference Figure 1 and Figure 4 as well as Figure 5Both the lower shell 3 and the upper shell 7 are equipped with stabilizing mechanisms 16. Each stabilizing mechanism 16 includes fixing blocks 1600. Two sets of fixing blocks 1600 are located on either side of the slot 10 and the mounting groove 14, respectively. Each set of fixing blocks 1600 consists of two blocks. Guide rods 1601 are symmetrically fixed between the two fixing blocks 1600 in each set. Movable blocks 1602 are movably mounted on each of the two guide rods 1601. Mounting plates 1603 are symmetrically fixed on each of the movable blocks 1602, with the mounting plates 1603 close to both ends of the movable blocks 1602. Mounting tubes 1604 are symmetrically fixed on both the lower shell 3 and the upper shell 7. Mounting tubes 1604 are located on either side of the slot 10 and the mounting groove 14, and are positioned between the two movable blocks 1602. Movable rods 1605 are movably mounted on each mounting tube 1604, with one end of each movable rod 1605 fixed. An adjusting block 1606 is assembled, and an operating plate 1607 is fixedly mounted on both symmetrical sides of the adjusting block 1606. An adjusting rod 1608 is movably mounted on each operating plate 1607. The other end of the adjusting rod 1608 is movably assembled with the mounting plate 1603. A clamping ring 1609 is fixedly mounted on each of the two adjusting blocks 1606. One clamping ring 1609 is located between the ferrule connector 1 and the lower shell 3, and the other clamping ring 1609 is located between the ferrule connector 1 and the upper shell 7. The clamping ring 1609 is located outside the limiting tube 8. A connecting block 1610 is fixedly mounted on each of the movable blocks 1602. An extension rod 1611 is fixedly mounted on each of the connecting blocks 1610. A clamping ring 1612 is fixedly mounted on one end of each extension rod 1611. An adjusting bolt 1613 is threadedly mounted on each of the fixed blocks 1600. One end of the adjusting bolt 1613 is engaged with the movable block 1602.
[0032] In this invention, the connecting pipe is inserted into the ferrule connector 1, so that one end of the connecting pipe is close to the limiting pipe 8. The movable block 1602 is moved on the guide rod 1601. Under the action of the adjusting rod 1608, the adjusting block 1606 drives one end of the movable rod 1605 to move inside the mounting pipe 1604. The adjusting block 1606 drives the clamping ring 1609 to clamp one end of the connecting pipe on the limiting pipe 8. At the same time, the movable block 1602 drives the connecting block 1610 to move closer to each other. The extension rod 1611 on the connecting block 1610 drives the clamping ring 1612 to clamp the surface of the connecting pipe. At this time, the adjusting bolt 1613 is rotated on the fixed block 1600. One end of the adjusting bolt 1613 and the fixed block 1600 clamp the movable block 1602, so that the position of the movable block 1602 on the guide rod 1601 is fixed. At this time, the stability between the connecting pipe and the ferrule connector 1 is improved, which facilitates later use.
[0033] Working principle: The connecting tube is inserted into the compression fitting 1, so that one end of the connecting tube is close to the limiting tube 8. The movable block 1602 is moved on the guide rod 1601. Under the action of the adjusting rod 1608, the adjusting block 1606 drives one end of the movable rod 1605 to move inside the mounting tube 1604. The adjusting block 1606 drives the clamping ring 1609 to clamp one end of the connecting tube on the limiting tube 8. At the same time, the movable block 1602 drives the connecting block 1610 to move closer to each other. The extension rod 1611 on the connecting block 1610 drives the clamping ring 1612 to clamp the surface of the connecting tube. At this time, the adjusting bolt 1613 is rotated on the fixed block 1600. One end of the adjusting bolt 1613 and the fixed block 1600 clamp the movable block 1602, so that the position of the movable block 1602 on the guide rod 1601 is fixed. At this time, the stability between the connecting tube and the compression fitting 1 is improved, which facilitates later use.
