Description

Technical Field

[0001] This invention belongs to the field of textile dust removal technology, specifically relating to a dust removal device and method for textile workshops. Background Technology

[0002] With the continuous improvement of automation in the textile industry, textile workshops continuously generate large amounts of cotton lint, short fibers, textile debris, and fine dust during spinning, weaving, opening, and carding processes. These textile impurities are lightweight and highly volatile, easily accumulating on equipment surfaces, floors, and in the air. If not cleaned promptly and effectively, they not only create a dirty and chaotic production environment, affecting equipment operation and reducing textile processing quality, but also pose significant safety hazards such as dust accumulation and fiber buildup leading to fires.

[0003] In existing technologies, the dust collection bags of traditional dust removal equipment are mostly directly suspended and installed. There is no precise alignment structure or sealing and locking structure between the bag and the material discharge pipe. During the material discharge process, dust leakage and fiber scattering are very likely to occur, resulting in serious secondary dust generation. In addition, traditional dust removal equipment does not have the function of fiber shaking and compaction. Cotton lint and short fibers accumulate loosely, the internal gaps of the bag are large and the storage capacity is small, requiring frequent bag replacement, which greatly affects the continuity of dust removal operations.

[0014] A dust removal method for textile workshops includes the following steps: S1. Bag opening positioning: Hang the bag opening of the collection bag on the hook of the bag opening positioning component, start the bag opening positioning component, lift the bag to the position directly below the dust discharge pipe, continue to lift the bag so that the lower end of the dust discharge pipe extends into the inside of the collection bag, and complete the material dropping and positioning installation. S2, Bag opening lock: Activate the locking assembly to simultaneously clamp the outer wall of the bag opening and the outer wall of the dust discharge pipe, thereby achieving a seal at the connection between the bag opening and the dust discharge pipe, effectively preventing fiber dust from spilling out during the material feeding process. S3. Dust collection and filtration: Activate the filtration components to filter the dusty air containing cotton lint and short fibers in the textile workshop through the first filter cotton, cyclone dust collector and the second filter cotton. The purified gas is discharged to the outside through the exhaust pipe under the action of the exhaust fan. S4. Shaking and compacting: When loose textile fiber waste accumulates inside the bag, the shaking and compacting component is activated to clamp the side wall of the bag and shake it back and forth, thereby shaking and compacting the loose cotton inside the bag. S5. Bag Replacement: After the bag is full, the locking assembly releases the grip on the bag opening. Then, the waste collection box slides outward through the shifting assembly along with the support plate and tray, and the bag full of waste is removed, completing the bag replacement.

[0015] 1. The beneficial effects of this invention are as follows: The L-shaped hook in the bag opening positioning assembly hooks the bag opening of the collection bag onto the positioning ring, and then the driving device drives the slider to rise along the slide rod, automatically raising the bag to directly below the dust discharge pipe and allowing the dust discharge pipe to extend into the bag, completing the material placement and installation. At the same time, the bidirectional screw in the locking assembly drives two sets of moving plates to move towards each other, causing the semi-circular locking arc plate to close and tightly hug the bag opening and the outer wall of the dust discharge pipe. Combined with the elastic pre-tightening force provided by the tension spring, the rubber pad is tightly attached to the bag surface, forming a reliable sealing and locking structure. This solves the problems of traditional collection bags being directly placed on the dust outlet without positioning, easy to fall off, and air leakage and dust return. It realizes the rapid positioning, opening and sealing of the bag opening, significantly reducing the intensity of manual operation and the risk of dust exposure.

[0016] 2. The beneficial effects of the present invention are as follows: the drive device three in the shaking and compaction assembly drives the clamping plate to clamp the side wall of the bag, and then the drive device four drives the U-shaped frame to move back and forth along the slide groove three, so as to periodically shake and compact the loose textile fiber waste in the bag, so that the waste is evenly distributed in the bag and the volume is greatly compressed, significantly increasing the single bag loading capacity, reducing the frequency of bag replacement, and improving the continuous operation efficiency of the dust removal system.

A vertical plate 9 is symmetrically fixed to the upper surface of the support plate 7. The vertical plate 9 provides a vertical mounting reference and structural support for the bag opening positioning component 12, the shaking and compaction component 15, and the mounting plate 10. The mounting plate 10 is located on the inner side of the vertical plate 9. The mounting plate 10 provides an integrated mounting platform for the bag opening positioning component 12 and the locking component 13. A filter component 11 for multi-stage filtration and separation of the inhaled dusty air is located on the inner side of the housing 1. A bag opening positioning component 12 for positioning and opening the collection bag is installed on the inner side of the mounting plate 10. A locking component 13 for clamping and sealing the opened bag opening is installed on the lower surface of the mounting plate 10. A shaking and compaction component 15 for shaking and compacting the textile fiber waste collected inside the bag is installed on the inner side of the vertical plate 9. A displacement component 17 is located between the support plate 7 and the waste collection frame 6.

[0021] Please see Figure 2The filter assembly 11 includes a first filter cotton 110 fixedly disposed inside the housing 1. The first filter cotton 110 is used to intercept large clumps of textile lint in the airflow. A partition is provided in the middle of the inner side of the housing 1. The partition serves to separate the chambers and divides the interior of the housing 1 into a first chamber and a second chamber. The partition physically isolates the two-stage filtration spaces. The first filter cotton 110 is disposed in the first chamber, so that the dust-laden air undergoes coarse filtration pretreatment before entering the cyclone separator. The output end of the intake fan 2 is connected to the first chamber. A conveying pipe 111 is fixedly connected to the inner side of the housing 1. The conveying pipe 111 serves as a conveying channel for the airflow after coarse filtration. One end of the conveying pipe 111 is connected to the first cavity to ensure that all the airflow after coarse filtration enters the conveying pipe. A conveying fan 112 is fixedly installed on the conveying pipe 111. The conveying fan 112 provides additional pressurization power for the airflow to enter the cyclone dust collector 113. A cyclone dust collector 113 is fixedly installed on the front side of the housing 1. The cyclone dust collector 113 uses centrifugal force to separate the main textile fibers in the airflow. Separated from the gas phase, the airflow is connected at the outlet of the conveying pipe 111 to the tangential inlet of the cyclone dust collector 113. The tangential inlet creates a high-speed rotating flow field within the dust collector. A dust collection hopper 114 is fixedly connected to the lower end of the cyclone dust collector 113. The dust collection hopper 114 collects the settled textile fibers and guides them to the dust discharge pipe 115. The lower end of the dust collection hopper 114 is also fixedly connected to the dust discharge pipe 115, which vertically guides the fiber waste from the dust collection hopper 114 into the lower collection bag. A valve is provided on 15. The outlet end of the cyclone dust collector 113 is fixedly connected to a second conveying pipe 116. The other end of the second conveying pipe 116 is connected to the second chamber. The second conveying pipe 116 introduces the relatively clean airflow after cyclone separation into the second chamber for fine filtration. A second filter cotton 117 is fixedly installed inside the second chamber. One end of the outlet pipe 4 is connected to the second chamber. The second filter cotton 117 acts as a terminal fine filtration barrier, capturing the fine dust that the cyclone separation failed to remove, and ensuring that the final emission gas meets environmental protection standards.

[0022] Please see Figure 3 and Figure 4The bag opening positioning assembly 12 includes a positioning ring 121 fixedly installed inside the mounting plate 10. The positioning ring 121 serves as the opening and shaping skeleton of the bag opening. Multiple hooks 122 are fixedly installed in an array on the outer periphery of the positioning ring 121.

[0026] Please see Figure 1-7A dust removal method for textile workshops includes the following steps: S1. Bag opening positioning: Hang the bag opening of the collection bag on the hook 122 of the bag opening positioning component 12, start the bag opening positioning component 12, lift the bag to the position directly below the dust discharge pipe 115, continue to lift the bag, so that the lower end of the dust discharge pipe 115 extends into the inner side of the collection bag, and complete the material dropping and positioning installation. S2, Bag opening lock: Activate the locking assembly 13 to simultaneously clamp the outer wall of the bag opening and the outer wall of the dust discharge pipe 115, thereby achieving a seal and locking at the connection between the bag opening and the dust discharge pipe 115, effectively preventing fiber dust from spilling out during the material feeding process. S3. Dust collection and filtration: Activate the filter assembly 11 to filter the dusty air containing cotton lint and short fibers in the textile workshop through the first filter cotton 110, the cyclone dust collector 113 and the second filter cotton 117. The purified gas is discharged to the outside through the exhaust pipe 4 under the action of the exhaust fan 5. S4. Shaking and compacting: When loose textile fiber waste accumulates inside the bag, start the shaking and compacting component 15 to clamp the side wall of the bag and shake it back and forth, thereby shaking and compacting the loose cotton inside the bag. S5. Bag replacement: After the bag is full, the locking assembly 13 releases the grip on the bag opening, and then the waste collection box 6 slides outward through the shifting assembly 17 along with the support plate 7 and the support tray 8, and the bag full of waste is taken out, thus completing the bag replacement.

[0027] In this embodiment, the drive device 4 158 is a hydraulic cylinder, and the hydraulic cylinder is model MOB32-200, which can be replaced according to the actual situation.

[0028] In this embodiment, drive device 125, drive device 2 141 and drive device 3 156 are all servo motors, and the servo motors are Delta ECMA-C11020RS, which can be replaced according to the actual situation.

[0029] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0030] It should be noted that during operation, the bag opening of the collection bag is first hooked onto the L-shaped hook 122 on the outer periphery of the positioning ring 121. Then, the drive device 125 is started to drive the slider 124 to slide upward along the slide groove 123, so that the positioning ring 121 is raised to the bottom of the dust discharge pipe 115 and continues to rise until the lower end of the dust discharge pipe 115 extends into the bag to complete the alignment. Then, the drive device 2141 is started to drive the bidirectional lead screw 140 to rotate, and the two sliders 2139 on both sides move towards each other along the long groove, pushing the two sets of locking arc plates 135 to close synchronously. Under the elastic pre-tightening force of the tension spring 138, the rubber pad 136 tightly hugs the bag opening and the outer wall of the dust discharge pipe 115 to achieve a seal and lock. Next, the intake fan 2 is turned on. The dusty air in the textile workshop enters the first chamber of the box 1 through the intake pipe 3. Large clumps of cotton are intercepted by the first filter cotton 110. The conveying fan 112 draws the coarsely filtered airflow through the first conveying pipe 111 to the cyclone dust collector 113. After the airflow enters in a tangential manner, it forms a high-speed rotating flow field. The textile fibers settle into the dust collection hopper 114 under the action of centrifugal force and fall into the cloth bag through the dust discharge pipe 115. The separated airflow enters the second chamber through the second conveying pipe 116. After the fine dust is filtered by the second filter cotton 117, it is discharged outside the box 1 through the exhaust pipe 4 and the exhaust fan 5. During the collection process, when the fibers inside the bag are loose and accumulated, the drive device 156 is activated to push the clamping plate 154 to clamp the side wall of the bag. The anti-slip pad 155 increases friction to prevent slippage. At the same time, the drive device 158 is activated to drive the slider 152 to move up and down along the slide groove 151, causing the U-shaped frame 153 and the clamping plate 154 to shake the bag as a whole, which promotes the compaction and settling of the loose fibers inside the bag to increase the loading capacity. After the bag is full, the drive device 141 is reversed to open the locking arc plate 135 to loosen the bag opening, and the full bag is removed, sealed, and transported away.
