Description

Technical Field

[0001] The utility model relates to a dust filter anti-fiber winding sealing structure, belonging to the technical field of textile dust filtering equipment. Background Art

[0002] At present, the wool felt sealing ring fixed on the suction arm and its core sleeve rotates synchronously, the middle section of the suction nozzle in the dust filter is connected and fixed to the box body, and the wool felt sealing ring is close to the middle section of the suction nozzle, sealing the middle section of the suction nozzle. The external small fan absorbs the fibers on the mesh surface through the suction nozzle middle section and the suction arm on the core sleeve. However, when the external small fan is turned on, the suction nozzle middle section is under negative pressure, and the fiber-containing air in the box body will be sucked into the middle section of the suction nozzle through the gap of the wool felt sealing ring. The fibers contained in the air will hang in the gap of the wool felt sealing ring and merge with the fibers sucked from the suction arm to form entanglements. The more entanglements there are, the more they will become, and the suction channel will be blocked. When the fibers are entangled, they will be damaged, affecting their recycling. When the suction channel is blocked and needs to be cleaned, the dust filter must be turned off before entering the box body to remove the hooked and entangled fibers. At this time, the process production line connected to the dust filter can only stop production. In addition, when the dust filter is running, there is negative pressure inside the box, and the middle part of the suction nozzle will move inward due to the deformation of the wall panel, squeezing the wool felt sealing ring close to it. Over time, the wool felt sealing ring will deform and bend inward, causing the seal to fail. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a dust filter anti-fiber winding sealing structure based on the above-mentioned existing technology, so as to avoid the fibers being adsorbed and hooked on the wool felt sealing ring, reduce the damage of fiber winding, improve the recycling rate of the fibers, avoid the wool felt sealing ring being squeezed and causing sealing failure, and increase the service life of the wool felt door sealing ring.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: a dust filter anti-fiber winding sealing structure, comprising a box body, a horizontally arranged core sleeve is provided in the box body, a suction arm is provided on the core sleeve, the suction arm inlet faces the mesh surface of the dust filter, and the suction arm outlet is connected with the inner cavity of the core sleeve; a suction nozzle middle section is provided in the box body, one end of the suction nozzle middle section is connected with the core sleeve outlet, a wool felt sealing ring is provided at the junction of the core sleeve outlet and the suction nozzle middle section, one end of the wool felt sealing ring is fixed to one end of the suction nozzle middle section by a fixing part, and the other end of the wool felt sealing ring is sleeved on the outer periphery of the core sleeve; the inner cavity of the core sleeve and the inner cavity of the suction nozzle middle section form an air suction channel; the other end of the suction nozzle middle section is fixed to the box body and connected to the external fan through an external air suction pipe.

[0005] The cross section of the wool felt sealing ring is trumpet-shaped, and the wool felt sealing ring is arranged horizontally.

[0006] The fixing member includes a pressing plate, which is pressed on the side of the large end of the wool felt sealing ring, so that the wool felt sealing ring is arranged between the pressing plate and one end of the middle section of the suction nozzle, and the three are fixedly connected by fixing screws.

[0007] A rubber ring is also provided, and the rubber ring is sleeved on the wool felt sealing ring.

[0008] Compared with the prior art, the advantages of the present invention are: a dust filter anti-fiber entanglement sealing structure not only improves the sealing effect, but also prevents fibers in the housing from being sucked onto the wool felt sealing ring and entangled with fibers sucked in by the suction arm, thereby reducing fiber entanglement damage and improving fiber recovery. When the dust filter housing is deformed by negative pressure, the middle section of the suction nozzle and the wool felt sealing ring can slide around the outer periphery of the core sleeve, preventing the wool felt sealing ring from being squeezed, deformed, and flanging, which could cause sealing failure, thereby increasing the service life of the wool felt sealing ring.

[0012] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 、 2As shown, a dust filter anti-fiber winding sealing structure in this embodiment includes a housing 4, within which is a horizontally arranged core sleeve 2. A suction arm 1 is provided on the core sleeve 2, with the inlet of the suction arm 1 facing the mesh surface of the dust filter and the outlet of the suction arm 1 connected to the inner cavity of the core sleeve 2. A suction nozzle middle section 3 is provided within the housing 4, one end of which is in contact with the outlet of the core sleeve 2. A trumpet-shaped wool felt sealing ring 6 is provided at the junction of the outlet of the core sleeve 2 and the nozzle middle section 3, with a center fitting hole. The wool felt sealing ring 6 is arranged horizontally, with one side of the large end of the wool felt sealing ring 6 abutting one end of the nozzle middle section 3. An annular pressure plate 8 is pressed against the other side of the large end of the wool felt sealing ring 6, so that the wool felt sealing ring 6 is located between the pressure plate 8 and one end of the nozzle middle section 3. The three are fixedly connected by a fixing screw 5. The small end of the wool felt sealing ring 6 is sleeved around the outer periphery of the outlet of the core sleeve 2, so that the outer periphery of the core sleeve 2 outlet is located within the wool felt sealing ring 6. The wool felt sealing ring seals the junction between the nozzle middle section and the core sleeve. The inner cavity of the core sleeve and the inner cavity of the nozzle section form a suction channel. The other end of the nozzle section is fixed to the box body and connected to the external fan through an external suction pipe. When the external fan is turned on, the inner cavity of the nozzle section is negatively pressurized, and the fibers on the mesh surface are sucked out through the suction arm and the suction channel.

[0014] One end of the wool felt sealing ring is fixed to the end of the middle section of the suction nozzle, and the other end is sleeved on the outer periphery of the core sleeve outlet. When the core sleeve and the suction arm rotate, the wool felt sealing ring remains stationary, and the outer periphery of the core sleeve outlet rotates within the wool felt sealing ring. The above-mentioned wool felt sealing ring is sleeved with a matching rubber ring 7, which, on the one hand, improves the sealing effect, and on the other hand, prevents the fibers in the box from being adsorbed and hooked on the wool felt sealing ring, and also prevents entanglement with the fibers sucked from the suction arm, thereby reducing fiber entanglement damage and improving the fiber recycling rate. When the dust filter box is deformed by negative pressure, the middle section of the suction nozzle and the wool felt sealing ring can slide on the outer periphery of the core sleeve, preventing the wool felt sealing ring from being squeezed, deformed, and flanging, which may cause sealing failure, thereby increasing the service life of the wool felt sealing ring.

[0015] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
