Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a dust collection device for textile workshops. Background Technology

[0002] The textile industry is a core component of light industry. During core production processes such as spinning and weaving, fiber dust and lightweight fiber lint of varying particle sizes are generated. Effective dust control in textile workshops is crucial for standardized, green, and safe operation, directly impacting the optimization of the production environment, occupational health of operators, and the recycling and reuse of textile raw materials. It has become a core requirement for the high-quality development of the textile industry. Currently, textile workshop dust removal technology is gradually developing towards spatially layered suction and gradient purification. Addressing the varying spatial height distribution characteristics of textile workshop dust due to differences in particle size and weight, multi-height suction structures are employed to achieve targeted capture of dust in different areas, becoming the mainstream design approach for textile dust removal equipment. Simultaneously, technologies such as airflow guidance, precise static pressure distribution, electret condensation, nanofiber filtration, and electrostatic capture have been widely and maturely applied in the purification systems of textile dust removal equipment, effectively improving the dust collection efficiency and air purification effect.

[0003] The aforementioned and existing related technologies often suffer from the following drawbacks: Existing equipment is mostly a single cavity or a simple layered structure, failing to divide the processing areas according to the particle size characteristics of dust at different heights in textile workshops. Furthermore, the height ratio of each area does not match the dust removal process requirements, resulting in the mixed processing of dust of different particle sizes. Ultrafine dust is easily sucked away by the airflow vortex at the air inlet, while coarse dust particles are easily blown up and diffused to the middle and upper layers by the high-pressure airflow, making it impossible to achieve precise targeted collection of dust of all particle sizes. In addition, the existing equipment lacks differentiated guidance and airflow convergence design at the air inlet, and the continuous impact of airflow in one direction easily leads to the accumulation and blockage of fiber dust, requiring frequent manual maintenance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is the shortcomings of the existing technology. To address this, we propose a dust collection device for textile workshops.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dust collection device for a textile workshop, including a dust collection box, the dust collection box including a box shell, a dust discharge pipe fixedly installed on the outside of the box shell, and the inside of the box shell is divided into three layers by a fixed plate, namely the upper layer area, the middle layer area and the lower layer area.

[0006] Each of the upper, middle, and lower zones has a conical shell on one side, and a regulating valve is installed on one side of the conical shell. The regulating valve is connected to the dust discharge pipe through a connecting pipe.

[0007] The outer sides of the upper, middle and lower zones are respectively provided with filter shell one, filter shell two and filter shell three. The fan blade opening of filter shell one is set upward, the fan blade opening of filter shell two is set horizontally, and the opening of filter shell three is set inclined downward.

[0008] Two sets of wedge blocks are fixedly installed inside the middle and lower zones. The two sets of wedge blocks and the airflow guiding and dust removal components set inside the middle and lower zones form an inclined airflow guiding channel. The airflow direction of the inclined airflow guiding channel toward the exhaust port of the conical shell collides with the airflow direction formed between the two sets of airflow guiding and dust removal components.

[0009] An exhaust pipe is fixedly installed at the air inlet of the conical shell. Two sets of connecting blocks are fixedly installed on the inner wall of the exhaust pipe. A cleaning plate is rotatably installed on the side of the two sets of connecting blocks that are close to each other. Elastic strips are fixedly installed inside the middle and lower layers. One end of the elastic strip is fixedly installed on the inner wall of the middle and lower layers, and the other end of the elastic strip is fixedly connected to the cleaning plate.

[0010] Preferably, the upper layer is an ultrafine dust polarization and electrostatic collection zone, the middle layer is a medium particle fiber cyclone separation and fine filtration zone, and the lower layer is a coarse particle fiber gravity settling pre-separation zone.

[0011] Preferably, multiple sets of arc-shaped guide vanes are fixedly installed inside the upper zone, and the multiple sets of arc-shaped guide vanes are evenly arranged along the airflow direction inside the upper zone.

[0012] Preferably, the flow guiding and dust removal assembly includes two sets of flow guide plates, which are parallel to the cross-sections of two sets of wedge blocks. Fan blades are rotatably installed inside each set of flow guide plates. A connecting shaft is fixedly installed on one side of the rotating shaft of the fan blades, and a lever is fixedly installed on the outside of the connecting shaft. The lever is correspondingly set with the elastic strip.

[0013] Preferably, the elastic strips in the middle layer and the lower layer have different tensions, with the tension of the elastic strip in the middle layer being greater than that in the lower layer.

[0014] Preferably, a torsion spring is fixedly installed inside both sets of connecting blocks, and a connecting rod is fixedly installed at one end of the torsion spring. The connecting rod is rotatably connected to the connecting block, and the end of the connecting rod away from the torsion spring is fixedly connected to the cleaning plate.

[0015] Preferably, the static pressure ratio of the upper, middle and lower layers is 1:2:3, and the regulating valve is used to adjust the static pressure of each layer.

[0016] Preferably, the tilt angle of the inclined guide channel is 45°-60°.

[0017] Preferably, the fixing plate is sealed to the inner wall of the outer shell of the box.

[0018] Preferably, the height ratio between the upper layer, middle layer, and lower layer is 2:1:1.

[0019] The technical effects and advantages of this invention are as follows:

[0020] In this invention, a fixed plate divides the interior of the dust collection box into three dedicated processing areas with a height ratio of 2:1:1. The upper layer is a polarization and electrostatic capture area for ultrafine dust, the middle layer is a cyclone separation and fine filtration area for medium-particle fibers, and the lower layer is a gravity settling and pre-separation area for coarse-particle fibers. This precisely corresponds to the dust particle size characteristics at different heights in the textile workshop, structurally preventing the mixing of dust particles of different sizes. The outer sides of the three layers are respectively equipped with filter shell one, filter shell two, and filter shell three. Filter shell one has upward-facing slats, filter shell two has horizontal slats, and filter shell three has downward-sloping slats, achieving directional and precise suction of dust at each height. After the airflow enters each layer, the upper layer uses multiple evenly arranged arc-shaped guide plates to straighten the airflow and guide it smoothly to the subsequent purification structure. Two sets of stainless steel wedges are fixedly installed inside the middle and lower layers, and these wedges are connected to the corresponding airflow guiding and dust removal components. The inclined guide channel forms an inclined flow channel, which guides the airflow from the exhaust port of the conical shell to converge and collide with the straight airflow between the two sets of flow guiding and dust removal components, avoiding blockage caused by continuous impact of airflow in one direction. When the fan blades of the flow guiding and dust removal components rotate, they drive the connecting shaft and the deflector to rotate synchronously. The deflector continuously triggers the elastic strips with different tensions in the middle and lower layers. One end of the elastic strip is fixed to the inner wall of the area, and the other end is connected to the cleaning plate at the air inlet of the conical shell. At the same time, the torsion spring inside the connecting block provides the reset power to the cleaning plate through the connecting rod, driving the cleaning plate to swing back and forth to achieve automatic blockage removal. Each layer of the conical shell is equipped with an electric proportional adjustment valve on one side. The adjustment valve precisely controls the static pressure of the three layers to a ratio of 1:2:3 to adapt to the suction needs of each layer. Finally, the purified airflow from each layer is collected into the dust discharge pipe through the connecting pipe, realizing the integrated linkage operation of precise layered suction, flow guiding and anti-blockage, static pressure control and centralized discharge.

[0032] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0033] Reference Figure 1-2As shown, the present invention provides a technical solution: a dust collection device for a textile workshop, including a dust collection box 1, the dust collection box 1 including a box shell 11, a dust discharge pipe 12 fixedly installed on the outside of the box shell 11, the inside of the box shell 11 is divided into three layers: the upper layer 15 is an ultrafine dust polarization and electrostatic capture zone, the middle layer 16 is a medium particle fiber cyclone separation and fine filtration zone, and the lower layer 17 is a coarse particle fiber gravity settling pre-separation zone. The height ratio of the upper, middle and lower layers is 2:1:1. A conical shell 13 is provided on one side of each of the upper, middle and lower layers, and an adjustment mechanism is provided on one side of the conical shell 13. Valve 14, the regulating valve 14 is connected to the dust discharge pipe 12 via connecting pipe 141. The outer shell 11 of the housing is divided into three layers according to the dust particle size and characteristics: an ultrafine dust polarization and electrostatic collection zone, a medium particle fiber cyclone separation and fine filtration zone, and a coarse particle fiber gravity settling pre-separation zone. This allows for targeted graded suction and purification of dust at different heights in the textile workshop, ensuring that each layer of dust removal structure is precisely matched with the dust characteristics. This avoids the problem of reduced purification efficiency caused by mixing dust of different particle sizes, achieving efficient collection of textile dust of all particle sizes. The upper, middle, and lower layers adopt a 2:1:1 ratio. The height-to-weight ratio design precisely adapts to the spatial requirements of each layer of dust removal processes. The lower layer provides ample settling space for coarse particles due to gravity. The middle layer, as the core purification zone, matches the structural layout requirements of cyclone separation and fine filtration. The upper layer is a compact working space for polarization condensation and electrostatic capture. While ensuring the dust removal efficiency of each layer, it achieves optimal utilization of the internal space of the dust collection box 1, taking into account both equipment integration and dust removal functionality. Each layer has a conical shell 13 on one side, which can effectively gather the drawn-in airflow, eliminate airflow eddies at the air inlet, enhance the local negative pressure effect, and prevent ultrafine dust from forming due to eddies. To address the issue of airflow escape, the regulating valves 14 installed on the sides of each conical shell 13 are designed to improve the efficiency of airflow extraction and introduction at each layer. These valves allow for independent and precise control of the static pressure of the upper, middle, and lower layers, ensuring stable operation of the three layers at a pressure extraction ratio of 1:2:3. This adapts to the extraction wind speed requirements of each layer. Simultaneously, the regulating valves 14 are connected to the dust discharge pipe 12 via connecting pipe 141, enabling integrated centralized discharge of the purified airflow from the three layers. This simplifies the equipment piping layout, improves the space utilization and operational convenience of the dust collection box 1, and allows for a highly efficient and interconnected dust removal closed loop formed by layered extraction, graded purification, and centralized dust discharge.

[0034] Reference Figure 3-4As shown in this implementation scheme: Filter housing 151, filter housing 161, and filter housing 171 are respectively installed on the outer sides of the upper zone 15, middle zone 16, and lower zone 17. The fan-shaped opening of filter housing 151 is set upwards, the fan-shaped opening of filter housing 261 is set horizontally, and the opening of filter housing 171 is set inclined downwards. The upward-facing fan-shaped opening of filter housing 151 can maximize the coverage of the high-altitude area of ​​the workshop, forming an upward suction force on the ultrafine fiber dust floating in the upper layer, effectively preventing fine particles from escaping due to air buoyancy, and improving the collection range and efficiency of high-altitude dust. The horizontal fan-shaped opening of filter housing 261 matches the dust emission direction of the textile workshop operation area, which can accurately capture dust. The system precisely captures medium-sized fiber dust that escapes horizontally from the operating position of the middle layer equipment, achieving comprehensive dust extraction in the work area. The downward-sloping opening of filter shell 171 conforms to the gravity settling characteristics of the coarse fiber particles at the bottom layer. While extracting dust settled on the ground, it prevents the high-pressure airflow from blowing the coarse particles at the bottom layer back up and spreading them to the middle and upper layers. It also prevents ground debris from being accidentally sucked into the box. At the same time, it guides coarse particles into the lower layer 17 along the inclined direction, improving the initial efficiency of gravity settling pre-separation at the bottom layer. The opening direction of the three filter shells is designed specifically according to the dust removal needs of each layer, making the extraction direction highly compatible with the dust movement characteristics, achieving precise targeted collection of dust in the entire space, and significantly improving the overall extraction efficiency of the equipment.

[0035] Reference Figure 3-5 As shown in this embodiment: multiple sets of arc-shaped guide plates 152 are fixedly installed inside the upper zone 15; the middle zone 16 and the lower zone 17 are both fixedly installed with airflow guiding and dust removal components 18. The multiple sets of arc-shaped guide plates 152 inside the upper zone 15 can smoothly guide the intake of ultrafine dust airflow, eliminate the eddies and negative pressure dead zones formed in the airflow box, and make the airflow flow unidirectionally and evenly to the subsequent purification module along the preset path, enhance the negative pressure gathering effect of the upper zone 15, improve the contact efficiency between ultrafine dust and the purification components, and at the same time, the arc-shaped structure has no sharp corners, The absence of protrusions effectively prevents microfibers from entangled and adhering to the plate surface, ensuring the smooth flow of airflow channels within the upper zone 15. The airflow guiding and dust removal components 18 adapted within the middle zone 16 and lower zone 17 promptly clear the exhaust ports, preventing fiber and dust accumulation and blockage of airflow channels within the chamber. This ensures the grading efficiency of cyclone separation in the middle zone 16 and the pre-separation effect of gravity settling in the lower zone 17, allowing the middle zone 16 and lower zone 17 to achieve airflow guidance while simultaneously preventing blockage and removing dust, thus improving the continuous operation stability and dust removal efficiency of the equipment.

[0036] Reference Figure 3-5As shown in this embodiment: two sets of wedge blocks 1611 are fixedly installed inside the middle layer 16 and the lower layer 17. The two sets of wedge blocks 1611 and the airflow guiding and dust removal components 18 form an inclined airflow guiding groove 1612. The airflow direction of the inclined airflow guiding groove 1612 towards the exhaust port of the conical shell 13 collides with the airflow direction formed between the two sets of airflow guiding and dust removal components 18. This effectively solves the problem of airflow continuously flowing towards one air inlet in the same direction, causing dust blockage at the air inlet. It achieves the design effect of the airflow tilting upward from both sides converging with the airflow entering the air inlet in a straight line before entering the conical shell 13.

[0037] This structural design precisely addresses the dust characteristics and airflow bottlenecks in the middle and lower zones 16 and 17. The inclined guide channels 1612, formed by the two sets of wedge-shaped blocks 1611 and the airflow guiding and dust-removing components 18, guide the medium-particle fiber dust airflow in the middle zone 16 and the coarse-particle fiber dust airflow in the lower zone 17 into upward-sloping airflows on both sides. This airflow intersects and collides with the straight airflow formed between the two sets of airflow guiding and dust-removing components 18. On one hand, this disperses the adhering fiber clumps and dust agglomerates in the airflow, preventing fiber clumps from clogging the exhaust port of the conical shell 13 and ensuring smooth airflow. On the other hand, the convergence of the airflows forms a uniform and stable mixed airflow, avoiding unidirectional flow. The continuous impact of airflow on the air inlet causes localized dust accumulation, allowing the dust to enter the conical shell 13 evenly and dispersedly. This further enhances the grading efficiency of the cyclone separation in the middle zone 16 and the pre-separation effect of gravity settling in the lower zone 17. At the same time, the tilt angle of the inclined guide channel 1612 is adapted to the negative pressure requirements of the middle zone 16 and the lower zone 17. Combined with the airflow confluence design, it does not increase local wind resistance but strengthens the suction traction force of the airflow, adapting to the three-layer 1:2:3 pressure suction ratio operation requirements. While solving the problem of air inlet blockage, it further improves the dust removal stability and airflow utilization efficiency of the middle zone 16 and the lower zone 17, ensuring long-term continuous operation of the equipment without the need for frequent air inlet cleaning.

[0038] Reference Figure 3-6 As shown in this embodiment: the flow guiding and dust removal assembly 18 includes two sets of flow guiding plates 181. The two sets of flow guiding plates 181 are parallel to the cross-sections of the two sets of wedge blocks 1611 respectively. Fan blades 182 are rotatably installed inside the two sets of flow guiding plates 181. A connecting shaft 183 is fixedly installed on one side of the rotation shaft of the fan blade 182. A lever 184 is fixedly installed on the outside of the connecting shaft 183.

[0039] Reference Figure 3-6As shown in this embodiment: the upper zone 15, the middle zone 16, and the lower zone 17 are all separated by a fixing plate 162. The fixing plate 162 is fixedly connected to the inner wall of the outer shell 11. Elastic strips 163 are fixedly installed inside the middle zone 16 and the lower zone 17. One end of the elastic strip 163 is fixedly installed on the inner wall of the middle zone 16 and the lower zone 17, and the other end is fixedly installed at the air inlet of the conical shell 13. The elastic strips 163 in the middle zone 16 and the lower zone 17 have different tensions. Simultaneously, when the connecting shaft 183 drives the lever 184 to rotate, it continuously triggers the elastic strips 163 to tighten and loosen. This structure uses a differentiated tension elastic strip 163 design to precisely adapt to the different suction pressures and dust material characteristics of the middle zone 16 and the lower zone 17. The middle zone 16 corresponds to medium-particle fiber dust and medium-high negative pressure suction. The lower zone 17 corresponds to coarse-particle fiber dust and low negative pressure suction. Different tensions drive the cleaning plate 133 to form a matching vibration frequency, achieving precise unblocking of dust with different particle sizes and adhesion. This ensures that the air inlet unblocking capacity is highly compatible with the dust removal needs of each layer. At the same time, the rotation of the connecting shaft 183 and the lever 184 of the flow guiding dust removal component 18 automatically triggers the tensioning and restoring of the elastic strip 163. No additional power components are required, realizing the linkage and energy saving of the equipment structure. The reciprocating elastic movement of the elastic strip 163 can continuously form a dynamic vibration on the air inlet of the conical shell 13, fundamentally preventing fiber dust from bridging and accumulating at the air inlet. This effectively solves the problem of air inlet blockage under different suction conditions, ensuring the continuity and smoothness of airflow suction in the middle zone 16 and the lower zone 17, and adapting to the stable operation of the three-layer 1:2:3 pressure suction ratio.

[0040] Reference Figure 3-9 As shown in this embodiment: an exhaust pipe 131 connected to the regulating valve 14 is fixedly installed at the air inlet of the conical shell 13. Two sets of connecting blocks 132 are fixedly installed on the inner wall of the exhaust pipe 131. A cleaning plate 133 is rotatably installed on the side of the two sets of connecting blocks 132 that are close to each other. One end of the cleaning plate 133 is fixedly connected to one end of the elastic strip 163.

[0041] Two sets of connecting blocks 132 provide a stable rotational support foundation for the cleaning plate 133, ensuring the smoothness of rotation and structural stability of the cleaning plate 133 during vibration, and preventing loosening of the connection due to vibration. The fixed connection between the cleaning plate 133 and the elastic strip 163 realizes the efficient transmission of the elastic force of the elastic strip 163 from tension to recovery to the rotational force of the cleaning plate 133. This allows the reciprocating elastic motion of the elastic strip 163 to be directly converted into the reciprocating oscillation of the cleaning plate 133 at the air inlet of the conical shell 13, so that the cleaning plate 133 can directly act on the fiber dust accumulated at the air inlet and disperse the dust through mechanical oscillation. The condensation and scraping of adhering fiber lint, combined with the vibration effect of the elastic strip 163, significantly improves the unblocking efficiency of the air inlet. At the same time, the swinging working range of the clearing plate 133 precisely covers the effective suction area of ​​the conical shell 13 air inlet, achieving unobstructed clearing without affecting the normal airflow intake. Together with the elastic strip 163, the lever plate 184, and the connecting shaft 183, it forms an integrated air inlet linkage unblocking structure, allowing the middle layer zone 16 and the lower layer zone 17 to achieve graded airflow guidance while completing the automatic and continuous clearing of the air inlet, effectively improving the continuous operation stability of the equipment and reducing the frequency of manual maintenance.

[0042] Reference Figure 3-9As shown in this embodiment: Torsion springs 1321 are fixedly installed inside both sets of connecting blocks 132. A connecting rod 1322 is fixedly installed at one end of each torsion spring 1321. The connecting rod 1322 is rotatably connected to the connecting block 132 and fixedly connected to the cleaning plate 133. The torsion spring 1321 inside the connecting block 132 and the connecting rod 1322 form an elastic rotational support structure, allowing the connecting rod 1322 to achieve flexible rotation between the cleaning plate 133 and the connecting block 132. The connection allows for the efficient transmission of the elastic torque of the torsion spring 1321 to the cleaning plate 133, forming a bidirectional elastic cooperation with the elastic tension of the elastic strip 163. When the lever 184 triggers the elastic strip 163 to tighten and pull the cleaning plate 133 to rotate, the torsion spring 1321 simultaneously stores force. When the elastic strip 163 returns to its original position, the torsion spring 1321 releases its elastic torque to assist the cleaning plate 133 in quickly resetting, thus creating a dual-power drive of elastic tension and torque reset for the reciprocating swing of the cleaning plate 133. The smoother and more stable oscillation significantly improves the dust removal effect on the air inlet of the conical shell 13. At the same time, the elastic buffering effect of the torsion spring 1321 can effectively offset the hard impact of the cleaning plate 133 during the oscillation process, preventing the connecting block 132 and the cleaning plate 133 from becoming loose or worn due to long-term vibration, thus extending the service life of the entire unblocking structure. Moreover, the elastic torque of the torsion spring 1321 can be adaptively matched according to the different tension of the elastic strip 163 in the middle layer 16 and the lower layer 17, so that the cleaning plate 133 with different vibration frequencies can maintain a stable oscillation amplitude, accurately matching the unblocking needs of each air inlet. Together with the elastic strip 163, the baffle plate 184, and the airflow and dust removal component 18, it forms an integrated linkage unblocking system, realizing the automation and continuity of the air inlet cleaning action of the conical shell 13. Without affecting the airflow suction efficiency of the air inlet, it structurally ensures the long-term effectiveness of the unblocking effect and further improves the stability of continuous operation of the equipment.

[0043] Working principle: The dust collection box 1 is sealed and divided into an upper zone 15, a middle zone 16, and a lower zone 17 with a height ratio of 2:1:1 by a fixed plate 162. The outer filter shells 151, 161, and 171 of the three layers have differentiated openings that draw in dust at corresponding heights in the workshop, with upward, horizontal, and downward inclined openings. Multiple sets of arc-shaped guide plates 152 in the upper zone 15 smoothly guide the intake of ultrafine dust airflow. Two sets of wedge-shaped blocks 1611 in the middle zone 16 and the lower zone 17 cooperate with the flow guiding and dust removal components 18 to form inclined flow guide grooves 1612, so that the inclined airflow on both sides of the guide cone shell 13 meets and collides with the straight airflow between the two sets of flow guiding and dust removal components 18. The rotation of the fan blade 182 drives the connecting shaft 183 and the lever 184 to rotate synchronously, continuously triggering the elastic strips 163 with different tensions in the middle layer 16 and the lower layer 17 to reciprocate tension and recovery. The elastic strips 163 pull the cleaning plate 133 on the inner wall of the connecting block 132 of the air inlet exhaust pipe 131 of the conical shell 13 to rotate. The torsion spring 1321 inside the connecting block 132 provides elastic reset power to the cleaning plate 133 through the connecting rod 1322, causing the cleaning plate 133 to swing back and forth at the air inlet of the conical shell 13. The regulating valve 14 on one side of each layer of the conical shell 13 precisely controls the static pressure of the three layers to a ratio of 1:2:3. The purified airflow of each layer is collected through the connecting pipe 141 and sent to the dust discharge pipe 12 for centralized discharge.
