Description

Technical Field

[0001] This utility model relates to the field of spunlace filter felt technology, and more specifically, it relates to an easy-to-clean polyester spunlace filter felt. Background Technology

[0002] Polyester spunlace filter felt is a fine fiber cloth made of interlaced fibers with uniformly distributed pores using nonwoven needle punching technology. The needle punched felt is produced by combining polyester staple fibers and polyester twisted yarn. The surface of the needle punched felt is post-treated by hot rolling, singeing, or coating to make it smooth and flat, and not easily clogged by dust. This filter material has a large porosity and good air permeability. It is an ideal filter material under normal temperature conditions and is often made into filter bags for use in dust filtration equipment.

[0003] In a Chinese patent with publication number CN201899936U, a polyester fiber spunlace filter felt is disclosed. In this technical solution, the spunlace filter felt is set up as an integral piece. Due to the large overall area, it is more laborious to clean, which affects the overall efficiency of the polyester spunlace filter felt during cleaning and makes it inconvenient to use quickly.

[0004] Furthermore, polyester needle-punched felt is mostly a single-layer structure, which has poor antistatic ability, and its impact resistance, tear resistance and deformation resistance are also average. Filter bags made from it are prone to breakage and deformation during use, and are prone to generating static electricity when filtering dust. Utility Model Content

[0030] Please see Figure 1-Figure 5 A type of easy-to-clean polyester spunlace filter felt includes a filter felt body 1. The filter felt body 1 has a first edge 2 and a second edge 3 on both sides. A snap-fit ​​block 4 is fixed on the outer wall of the first edge 2. A snap-fit ​​groove 5 is correspondingly opened on the outer wall of the second edge 3. The snap-fit ​​block 4 can enter the interior of the snap-fit ​​groove 5. A first hook and loop fastener 6 is provided on the outer wall of the snap-fit ​​block 4. A second hook and loop fastener 7 is correspondingly provided on the inner wall of the snap-fit ​​groove 5. The first hook and loop fastener 6 and the second hook and loop fastener 7 are in contact. The filter felt body 1 includes a filter layer 8. A membrane layer 9 is provided on both the upper and lower sides of the filter layer 8.

[0031] In this embodiment, an oil-absorbing layer 10 is provided on the outer wall of the coating layer 9, and an antistatic layer 11 is provided on the outer wall of the oil-absorbing layer 10. The antistatic layer 11 includes antistatic polyester filament 12, antistatic nylon filament 13, metal filament 14 and reinforcing filament 15. The antistatic layer 11 is formed by twisting antistatic polyester filament 12, antistatic nylon filament 13, metal filament 14 and reinforcing filament 15 together. The oil-absorbing layer 10 is made of oil-absorbing paper, and the coating layer 9 is a PTFE hydrophobic, oil-resistant and breathable membrane.

[0032] More specifically, users can separate multiple filter felt bodies 1 using the first Velcro 6 and the second Velcro 7 to make them individual materials, thus facilitating subsequent cleaning. This design avoids the difficulty of cleaning due to excessive area and facilitates quick cleaning. Users can also use the first Velcro 6 and the second Velcro 7 to attach the two ends of the filter felt body 1 to form a cylinder, making it easy to install into dust filtration equipment. By setting the filter layer 8, dust particles in the exhaust gas can be filtered. By setting the membrane layer 9 and the oil-absorbing layer 10, the oil and water resistance of the filter felt body 1 can be increased, greatly reducing the possibility of the filter layer 8 being corroded by water or oil during use. By setting antistatic polyester filaments 12, antistatic nylon filaments 13, metal wires 14 and reinforcing filaments 15 inside the antistatic layer, the antistatic ability can be effectively improved while the overall strength of the filter felt body 1 is improved, preventing deformation and tearing.

[0033] Please see Figure 4 and Figure 5 As an embodiment for cutting the filter felt body 1: The outer end of the filter felt body 1 is provided with a protective shell 16, and a material shaft 17 is rotatably provided inside the protective shell 16. The filter felt body 1 is wound around the outer wall of the material shaft 17. One end of the material shaft 17 passes through the protective shell 16 and is fixedly provided with a turntable 18. The outer wall of the turntable 18 is provided with a handrail 26. Multiple handrails 26 are provided and arranged in a circumferential shape. The outer wall of the protective shell 16 is provided with a discharge pipe 19. The upper end face of the discharge pipe 19 and both sides are provided with guide cylinders 20. The guide cylinders 20 are slidably provided with guide posts 21. The upper end of the guide post 21 is fixedly provided with a pressure block 22. The lower end face of the pressure block 22 is fixedly provided with a cutting blade 23. The upper end face of the discharge pipe 19 is provided with an avoidance hole 24. The lower end of the cutting blade 23 is located inside the avoidance hole 24.

[0034] Specifically, the user can rotate the handle 26 to make the turntable 18 drive the material shaft 17 to rotate, so as to export the filter felt body 1 inside the protective shell 16. Then, by pressing the pressure block 22, the cutting blade 23 passes through the avoidance hole 24 and contacts the filter felt body 1 to achieve the effect of cutting the filter felt body 1, which is convenient for subsequent use.

[0035] Please refer to Figure 5 As a further embodiment of pressing the pressure block 22: the lower end of each guide post 21 is provided with a spring 25, and the other end of each spring 25 is fixedly connected to the inner wall of the guide cylinder 20.

[0036] Specifically, the guide post 21 can be made to automatically spring back when not pressed, which facilitates the subsequent feeding of the filter felt body 1.

[0037] In summary, when using the overall equipment: the user can use the first Velcro 6 and the second Velcro 7 to disassemble the multiple filter felt bodies 1 into individual pieces, facilitating subsequent cleaning. This design avoids the difficulty of cleaning due to excessively large areas, enabling quick cleaning. Furthermore, the user can use the first Velcro 6 and the second Velcro 7 to fasten the ends of the filter felt body 1, forming a cylindrical shape for easy installation into the dust filtration equipment. The filter layer 8 filters dust particles in the exhaust gas, and the membrane layer 9 and oil-absorbing layer 10 increase the oil and oil resistance of the filter felt body 1. The water resistance greatly reduces the risk of the filter layer 8 being corroded by water or oil during use. By setting antistatic polyester filaments 12, antistatic nylon filaments 13, metal wires 14 and reinforcing filaments 15 inside the antistatic layer, the antistatic ability can be effectively improved while the overall strength of the filter felt body 1 is increased, preventing deformation and tearing. The handle 26 can be rotated to make the turntable 18 drive the material shaft 17 to rotate, so as to export the filter felt body 1 inside the protective shell 16. Then, by pressing the pressure block 22, the cutting blade 23 passes through the avoidance hole 24 and contacts the filter felt body 1 to cut the filter felt body 1, which is convenient for subsequent use.
