Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and more specifically, to a tube bundle precision dust collector. Background Technology

[0002] Plastic-sintered tubes are made primarily of 3 million units of ultra-high molecular weight polyethylene powder, with conductive carbon black, glass microspheres, and high-density polyethylene powder as auxiliary materials. They are mixed and sintered into a microporous rigid matrix, and a polytetrafluoroethylene (PTFE) filter membrane layer is added to the surface. This constitutes a dual filtration system that includes membrane filtration and rigid body filtration, resulting in a high-precision and high-efficiency filter material. It also has the advantages of being oil-resistant, high-temperature resistant, acid and alkali resistant, wear-resistant, moisture-resistant, and recyclable. However, it also has disadvantages such as long production cycle, high cost, high power consumption, high filtration resistance, and non-flame retardant properties. Therefore, we have proposed a tube bundle precision dust collector. Utility Model Content

To clean the dust on the outside of the base fabric 7, the scraper 22 can be manually moved up and down. Example 3

[0035] Based on Embodiments 1 and 2, as shown in Figures 3, 7, 13, and 17, both ends of the U-shaped bracket 1 are provided with mounting grooves 26. The U-shaped bracket 1 can be installed using the mounting grooves 26 and bolts. The U-shaped bracket 1 has multiple sleeve holes 14, the inner diameter of which is equal to the outer diameter of the top end 4. There are 18 sleeve holes 14. Similarly, the number of components such as the top end 4, the perforated mesh tube 5, and the bottom end 6 are all 18. The end of the base fabric 7 is provided with an angled edge, the angle being the angle required for the base fabric 7 to wrap around the outside of the perforated mesh tube 5. The length of the base fabric 7 is longer than the actual length of the wound substrate, and the width of the base fabric 7 is 120 mm. The scraper 22 has two sliding holes 24.

[0036] It should be noted that this utility model is a tube bundle precision dust collector. During manufacturing, firstly, a perforated mesh tube 5 is rolled from a galvanized or stainless steel sheet. The length of the perforated mesh tube 5 is determined according to the user's requirements. The upper end 4 and lower end 6 are respectively attached to the upper and lower ends of the perforated mesh tube 5. Welding is performed at the perforations on the contact surfaces of the upper end 4, lower end 6, and perforated mesh tube 5 at three to four points. The welded areas on the outer side of the perforated mesh tube 5 are then ground smooth to form the filter tube body. Next, the cut base fabric 7 is wrapped around the perforated mesh tube 5, ensuring a seam width of 8-10mm to prevent air leakage. A hose clamp 8 is installed near the upper end 4 to fix the top of the base fabric 7. The wrapping length exceeds the filter tube body by 3-4cm. Cut the filter tubes in time, then insert the extended portion of the base fabric 7 into the lower end 6. Apply an appropriate amount of high-temperature sealant to the groove in the end cap 9 to prevent air leakage and dust leakage. Fasten the end cap 9 onto the bottom of the lower end 6. Rivet three rivets evenly on the outside of the end cap 9 to fix the base fabric 7. Then, fix the 18 filter tubes wrapped with the base fabric 7 to the top of the upper end 4 on the U-shaped bracket 1 with nuts 10. Fit scrapers 22 onto the outside of multiple filter tubes, and connect the bottom of each filter tube with connecting plates 2. Insert the outer protrusion 12 on the top of the connecting plate 2 into the inner groove 13 at the bottom of the end cap 9. Connect the end cap 9 and the connecting plate 2 with rivets. Finally, put the rubber sealing cap 11 on the top of the nut 10 on each upper end 4, and insert the connecting slide rod 17 into the connecting hole 15 and the sliding hole 24. Insert the countersunk screw 19 into the middle, so that the top thread of the countersunk screw 19 is installed into the inner cavity of the screw hole 18, and install the nut 21 on the outer thread of the external stud 20 at the top of the connecting slide rod 17. The manufacturing work is completed.

[0037] In use, dust is filtered through the base fabric 7 on the outside of the perforated mesh tube 5. The filtered gas enters the inner cavity of the perforated mesh tube 5 and is discharged from the top end 4, nut 10, and rubber sealing cap 11 at the top of the perforated mesh tube 5. The scraper 22 is moved up and down at regular intervals, and the scraping holes 23 on the scraper 22 clean the dust on the outside of the base fabric 7, ensuring the filtration effect of the dust collector. At the same time, the perforated mesh tube 5 is made of galvanized plate or stainless steel plate perforated mesh. The base fabric 7 can be made of 200g surface-coated non-woven fabric, ultra-fine fiber glass fiber filter, paper activated carbon felt, etc., achieving the requirements of low cost, low resistance, temperature resistance and flame retardancy. The collection efficiency of ultra-fine dust below 0.1μm can be maintained at 99.99%. It can be widely used in smoke and dust removal in various fields such as steel production, coal production, cement production, automobile manufacturing, medical and pharmaceutical, machinery manufacturing, laser welding, biological purification, electronic component manufacturing, food processing, aerospace and other fields.
