Description

Technical Field

[0001] The present application relates to the technical field of fiber processing dust removal devices, and in particular to a dust removal device for processing flax fibers in a workshop. Background Art

[0002] Flax fiber is the bast fiber under the epidermis of the stem of the herbaceous plant flax. It is the earliest natural plant fiber used by humans. Flax fiber has excellent properties of heat dissipation and breathability, moisture absorption and release, health care and antibacterial, and is widely used in clothing fabrics, decorative fabrics and other fields.

[0003] Flax fiber needs to go through multiple processing steps, including planting, harvesting, preliminary processing (threshing, impregnation, drying), fiber extraction, spinning, weaving, etc. The materials in the spinning process are dry, and a certain amount of fine fibers (dust) will float in the air during the spinning process. A dust removal device is needed to deal with the dust in the air. The traditional dust removal device is composed of a negative pressure fan, a dust hood, a dust exhaust pipe and other structures. The existing dust removal device still has the following disadvantages during use. During the processing of flax fiber in the workshop, there will be a small amount of fiber filaments in the dust in the air. During the dust removal process, the direct inhalation of fibers will cause certain interference to the negative pressure fan. Therefore, the existing dust removal device will set a filter plate at the air intake to filter the inhaled fiber filaments. However, the inhaled fiber filaments need to be cleaned regularly by workers, or the filter plate needs to be replaced regularly. The replacement cost is large, and it takes a certain amount of manpower and time. If it is not cleaned or replaced regularly, the dust removal effect will be affected.

[0004] To this end, the present application proposes a dust removal device for processing in a flax fiber workshop to solve the above-mentioned problems. Summary of the invention

[0057] Among them, a wind-driven mechanism 5 is also provided inside the filter cover 2, and the wind-driven mechanism 5 includes a rotating shaft 51 that passes through and is rotatably connected to the middle of the filter plate 6, and the side wall of the rotating shaft 51 is connected to a cleaning mechanism 13 located below the filter plate 6 for cleaning the fibers of the dust discharge part 62; the wind-driven mechanism 5 also includes a support frame 53 fixedly connected to the inner wall of the filter cover 2, the upper end of the rotating shaft 51 passes through the support frame 53 and is rotatably connected to the support frame 53, a support bearing is embedded in the middle of the support frame 53, and the rotating shaft 51 is fixedly connected to the inner ring of the support bearing.

[0058] The side wall of the rotating shaft 51 is fixedly connected with the fan blade 52 located above the filter plate 6. Under the action of the negative pressure wind force of the negative pressure fan 1, the fan blade 52 will rotate and thus drive the rotating shaft 51 to rotate.

The shielding strip 72 is a silicone shielding strip. When the cleaning rod 131 is about to enter the interior of the collection box 71, the auxiliary rod 132 on one side of the cleaning rod 131 will push the shielding strip 72 away, so that the fibers brushed off by the bristles 133 can smoothly enter the collection box 71 without being blocked and pushed down by the shielding strip 72.

When the bristles 133 enter the collection box 71, the plurality of intercepting rods 103 will intercept the fibers on the bristles 133. The intercepted fibers will fall into the collection box 71, and a small amount of fibers will remain on the intercepting rods 103.

[0062] In this embodiment, the outer end of the collection box 71 is connected to a box positioning mechanism 8 for supporting and positioning the collection box 71; the box positioning mechanism 8 includes a through slot 81 provided on the side wall of the filter cover 2, and the outer end of the collection box 71 is fixedly connected to an arc plate 82 that fits and is inserted into the through slot 81, and the arc plate 82 supports and positions the collection box 71. The depth of the through slot 81 is greater than the height of the collection box 71, so that the collection box 71 and the shielding strip 72 can be pulled out through the through slot 81 together; pour out the fibers collected in the collection box 71. The bottom end of the intercepting rod 103 is located above the upper end surface of the collection box 71, and will not hinder the collection box 71 from being pulled out.

[0064] Embodiment 2

[0065] The dust removal device for flax fiber workshop processing proposed by the present invention is based on the first embodiment. Figure 5 , Figure 7-Figure 8 As shown, this embodiment further includes: a lifting and pushing assembly 11 is provided through the upper end of the blocking portion 61, which is used to clean the fibers remaining on the pushed-down intercepting rod 103. The lifting and pushing assembly 11 includes a pair of L-shaped inserting rods 111 slidingly passing through the blocking portion 61, and the bottom ends of the two L-shaped inserting rods 111 are fixedly connected to the pushing plate 102; the L-shaped inserting rods 111 and the intercepting rod 103 are staggered (the intercepting rod 103 will not hinder the L-shaped inserting rod 111 from moving downward).

[0066] Specifically, a plurality of return springs 112 are disposed between the two L-shaped rods 111 and the blocking portion 61, the upper end of the return spring 112 is fixedly connected to the inner wall of the L-shaped rod 111, and the lower end of the return spring 112 is fixedly connected to the blocking portion 61. A transmission rod 113 is fixedly connected between the two L-shaped rods 111. When the return spring 112 is in the unfolded state, the transmission rod 113 maintains a certain distance from the blocking portion 61.

[0067] Furthermore, a lifting drive member 12 is provided on the side wall of the rotating shaft 51 . The lifting drive member 12 is located above the filter plate 6 and is used to drive the lifting and pushing assembly 11 to move up and down. The lifting drive member 12 and the cleaning mechanism 13 are staggered.

[0068] Specifically, the lifting drive member 12 includes a support rod 121 fixedly connected to the side wall of the rotating shaft 51 and located above the filter plate 6. The end of the support rod 121 is fixedly connected to a pressing block 122. The bottom end of the pressing block 122 is an arc surface. When the pressing block 122 moves in a circle through the transmission rod 113, it presses the transmission rod 113 downward. After the pressing block 122 moves away from the transmission rod 113, the L-shaped insertion rod 111 and the transmission rod 113 will return to their original positions upward under the action of the rebound force of several return springs 112.

[0069] The working principle of the present application is as follows: the device is installed on the indoor top of the workshop. When dust removal is in progress, the negative pressure fan 1 is started to make the port of the dust hood 3 in a negative pressure state, and the dust in the workshop is sucked in. The dust is sucked into the filter hood 2 through the dust hood 3, and the dust discharge part 62 will filter and intercept the fibers in the dust. After the dust is sucked in, it is collected in the dust collection hood, and the air is discharged outward through the exhaust pipe 4. In the present application, the fan blades 52 will rotate in the filter hood 2 under the action of wind force, and the rotation of the fan blades 52 drives the rotating shaft 51 to rotate. Under the action of the rotating shaft 51, the cleaning brush rod 131 will be driven to move in a circle, and then the bristles 133 will move in a circle at the bottom of the dust discharge part 62, and the fibers intercepted at the bottom of the dust discharge part 62 will be brushed off. The fibers will temporarily remain on the bristles 133. When the cleaning brush rod 131 and the bristles 133 move to the inside of the collection box 71, the interception rods 103 arranged in a row will block the fibers on the bristles 133 from falling into the collection box 71.

[0070] The auxiliary rods 132 on both sides of the cleaning rod 131 have the function that when the cleaning rod 131 moves to the edge of the collection box 71, the auxiliary rods 132 will first push the shielding strips 72 away, so that the bristles 133 and the fibers cleaned at the upper end can smoothly enter the collection box 71 (will not be brushed off by the shielding strips 72); the shielding strips 72 are provided to make the collection box 71 and the blocking portion 61 form a complete collection space, so as to prevent the fibers collected in the collection box 71 from being sucked out when the negative pressure drops. After the fibers on the bristles 133 are cleaned, the bristles 133 can maintain a good circular motion cleaning effect.

[0071] Furthermore, the rotation of the rotating shaft 51 will also drive the lifting driving member 12 to move in a circular motion on the upper end of the filter plate member 6. When the pressing block 122 moves to the upper part of the lifting pushing assembly 11, the pressing block 122 will press the transmission rod 113 downward, and the transmission rod 113 moves downward to drive the two L-shaped plug rods 111 to move downward, and then drive the pushing plate 102 to move vertically downward, scraping the residual fibers on the intercepting rod 103 and dropping them into the collecting box 71. This allows the intercepting rod 103 to maintain a good interception and cleaning effect.

[0072] The fibers in the collection box 71 can be poured out periodically as required, specifically by unscrewing the bolts between the protrusion 83 and the support ring 84, then pulling out the protrusion 83 and the arc plate 82, and then pulling out the collection box 71 to pour out the fibers collected in the collection box 71. It should be noted that after the arc plate 82 is inserted into the through groove 81, it not only supports the collection box 71, but also seals the through groove 81.

[0073] In summary, the structural design of the present application is ingenious. It intercepts the inhaled fibers during the dust removal process to prevent the fibers from damaging the negative pressure fan 1; and it can automatically clean the fibers intercepted at the lower end of the dust discharge section 62 to prevent the dust discharge section 62 from being blocked and affecting the dust removal effect. The interception rod 103 can clean the fibers on the bristles 133 into the collection box 71. During the cleaning process, the fibers remaining on the interception rod 103 can be intermittently cleaned to maintain the interception and cleaning effect of the interception rod 103. The entire device improves the efficiency of dust removal, enables the device to maintain a good dust removal effect for a long time, reduces damage to the negative pressure fan 1, extends the service life of the negative pressure fan 1, and saves energy and is environmentally friendly.
