Description

Technical Field

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

[0002] The original meaning of textiles comes from the general term for spinning and weaving. However, with the continuous development and improvement of the knowledge system and discipline of textiles, especially after the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, textiles today are no longer just traditional hand spinning and weaving, but also include nonwoven technology, modern three-dimensional weaving technology, modern electrostatic nano-web forming technology, etc., to produce clothing, industrial and decorative textiles.

[0003] In textile workshops, due to the large space, numerous personnel, and the significant amount of dust generated during the textile process, indoor air pollution is easily caused, potentially impacting the health of workers. Therefore, appropriate ventilation equipment is necessary. Existing dust removal equipment typically uses baghouse dust collectors to filter the air, cleaning the filter bags with pulsed high-pressure air after a period of use. While this method cleans the filter bags, a large amount of dust still adheres to their surface, reducing the dust removal efficiency and necessitating regular shutdowns for maintenance. Frequent maintenance contributes to the potential air pollution risks in textile workshops. Summary of the Invention

When the cleaning plate moves vertically, the air inlet pipe and dust outlet are mostly located on opposite sides of the lifting plate, resulting in higher air pressure on the side closer to the mounting plate and lower air pressure on the other side. Some air must pass through the mounting ring to enter the dust outlet. During this process, this airflow blows out dust from the brush area, achieving self-cleaning of the brushes. This method allows for cleaning of the filter bags without shutting down the machine, significantly extending the equipment downtime for maintenance and ensuring air quality in the textile workshop.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example This invention provides a dust collection device for textile machines, see [link to related document]. Figures 1-4 The system includes a housing 100, with an installation cavity formed inside the housing 100. A horizontal mounting plate 110 is fixedly installed inside the installation cavity, with a dust removal chamber 120 formed on the lower side and an air outlet chamber 130 formed on the upper side of the mounting plate 110. An air inlet pipe 140 and an air outlet pipe 150 are provided on the housing 100. One end of the air inlet pipe 140 is connected to the processing workshop, and the other end is connected to the dust removal chamber 120. The air outlet pipe 150 is connected to the air outlet chamber 130. An exhaust fan 160 is installed on the air outlet pipe 150.

[0020] A plurality of first mounting holes 111 are provided on the mounting plate 110, and a bag filter assembly 200 extending into the dust collection chamber 120 is disposed in the first mounting holes 111. A cleaning mechanism for cleaning the bag filter assembly 200 is provided on the mounting plate 110. During operation, the bag filter assembly 200 filters the extracted air, and the bag filter assembly 200 is cleaned periodically.

[0021] The bag filter assembly 200 includes a filter bag 210 and a support frame 220. The open end of the filter bag 210 is located at the first mounting hole 111. The filter bag 210 is located inside the dust collection chamber 120. The support frame 220 is located inside the filter bag 210 and is abutted against the first mounting hole 111.

[0022] The cleaning mechanism includes a cleaning plate 300, a cleaning component 400, a lifting component 500, a closing component 600, and a dust accumulation component 700.

[0023] A cleaning plate 300 is slidably installed within the dust collection chamber 120. A second mounting hole 310 is provided on the cleaning plate 300, concentrically positioned with the first mounting hole 111. A cleaning component 400 is installed within the second mounting hole 310, sleeved on the outside of the bag filter assembly 200, and used to clean the bag filter assembly 200. The lifting end of the lifting component 500 is connected to the cleaning plate 300, causing the cleaning plate 300 to slide parallel to the length of the bag filter assembly 200. A closing component 600 is located within the air outlet chamber 130. When cleaning dust from the bag filter assembly 200, the closing component 600 closes the first mounting hole 111. A dust collection component 700 connects the dust collection chamber 120 and the air outlet pipe 150, and filters and collects the passing air. The dust collection component 700 operates when cleaning the filter bag 210; otherwise, it does not operate.

[0024] Specifically, the cleaning assembly 400 includes a mounting ring 410 and brush bristles 420. The mounting ring 410 is threaded into the second mounting hole 310. Brush bristles 420 are evenly distributed on the inner sidewall of the mounting ring 410, with the length direction of the brush bristles parallel to the radial direction of the mounting ring 410. The bag filter assembly 200 passes through the mounting ring 410, and the brush bristles 420 abut against the sidewall of the bag filter assembly 200. When cleaning the filter bag 210, the cleaning plate 300 is moved vertically by the lifting assembly 500. During the movement, the brush bristles 420 on the inner side of the mounting ring 410 clean the filter bag 210.

[0025] The lifting assembly 500 includes a guide column 510, a lifting screw 520, a drive motor 530, and a mounting sleeve 540.

[0026] Multiple guide columns 510 are spaced apart. Guide holes 320 are provided on the cleaning plate 300, and the guide columns 510 pass through the guide holes 320. The lifting screw 520 and the guide columns 510 are parallel to the length direction of the bag filter assembly 200. The lifting screw 520 is rotatably connected to the mounting plate 110. One end of the lifting screw 520 is located in the air outlet chamber 130 and is connected to the drive motor 530. The other end of the lifting screw 520 is located in the dust collection chamber 120 and is threadedly connected to the mounting sleeve 540. A center hole 330 is provided at the center of the cleaning plate 300, and the lifting screw 520 and the mounting sleeve 540 pass through the center hole 330. The mounting sleeve 540 is fixedly connected to the cleaning plate 300. During operation, the output shaft of the drive motor 530 drives the lifting screw 520 to rotate. When the lifting screw 520 rotates relative to the mounting sleeve 540, the mounting sleeve 540 rises or falls with the lifting screw 520, thereby achieving the purpose of driving the cleaning plate 300 to move linearly.

[0027] The closing assembly 600 includes a support plate 610, a lifting plate 620, a first cylinder 630, and a cover 640.

[0028] The support plate 610 is fixed to the inner wall of the housing 100 and is located in the air outlet cavity 130. The first cylinder 630 is fixedly installed on the support plate 610. Multiple support plates 610 and first cylinders 630 are provided. During operation, multiple first cylinders 630 work synchronously.

[0029] The lifting plate 620 is located on the side of the support plate 610 near the mounting plate 110. A third mounting hole 621 and a connecting hole 622 are provided on the lifting plate 620. The third mounting hole 621 is concentrically arranged with the first mounting hole 111. When the filter bag 210 is not cleaned, the filtered air enters the air outlet pipe 150 through the connecting hole 622.

[0030] A cover 640 is threaded into the third mounting hole 621. The cover 640 includes a circular plate 641, a rubber gasket 642, a limiting ring 643, and a handle 644. The circular plate 641 is threaded into the third mounting hole 621. A rubber gasket 642 is provided on the side of the circular plate 641 near the mounting plate 110, and a handle 644 is provided at the end of the circular plate 641 away from the mounting plate 110. A limiting ring 643 is provided on the circumferential sidewall of the circular plate 641 near the handle 644. The diameter of the limiting ring 643 is larger than the diameter of the third mounting hole 621. When the filter bag 210 needs to be replaced, the cover 640 is removed by controlling the handle 644, and the operator can then pass through the third mounting hole 621 to replace the filter bag 210.

[0031] Understandably, in order to completely close the first mounting hole 111, the diameter of the third mounting hole 621 must be larger than that of the first mounting hole 111.

[0032] An L-shaped plate 650 is connected between the piston end of the first cylinder 630 and the lifting plate 620. When the piston end of the first cylinder 630 extends or retracts, the cover 640 opens or closes the first mounting hole 111.

[0033] A retaining ring 660 is provided on the side of the lifting plate 620 near the mounting plate 110. The retaining ring 660 is located outside all the covers 640, and the height of the retaining ring 660 protruding from the lifting plate 620 is the same as the height of the cover 640 protruding. The retaining ring 660 can protect the cover 640 and the bag filter assembly 200.

[0034] The ash collection assembly 700 includes an ash storage box 710, a support frame 720, a second cylinder 730, a sealing plate 740, a filter plate 750, a connecting pipe 760, and a control valve 770.

[0035] A dust outlet 170 is provided on the vertical side of the housing 100, away from the air inlet pipe 140. The dust outlet 170 is located on the side away from the mounting plate 110, and the connection between the air inlet pipe 140 and the housing 100 is located on the side closer to the mounting plate 110. With this arrangement, when the lifting plate 620 moves up and down vertically, the air inlet pipe 140 and the dust outlet 170 are located on opposite sides of the lifting plate 620, resulting in a higher air pressure on the side of the lifting plate 620 closer to the mounting plate 110 and a lower air pressure on the other side. Some air needs to pass through the mounting ring 410 to enter the dust outlet 170. During this process, this airflow can blow out the dust at the brush position, achieving self-cleaning of the brush.

[0036] The ash storage box 710 is fixed to one side of the box body 100 and is covered with a dust outlet 170. The support frame 720, the second cylinder 730, the sealing plate 740, and the filter plate 750 are located inside the ash storage box 710. The support frame 720 is fixedly installed on one side of the dust outlet 170, and the second cylinder 730 is fixedly connected to the side of the support frame 720 near the dust outlet 170. The sealing plate 740 is fixedly installed on the piston end of the second cylinder 730. When the piston end of the second cylinder 730 extends or retracts, the sealing plate 740 can close or open the dust outlet 170. Specifically, when it is necessary to clean the bag filter assembly 200, the first mounting hole 111 is closed and the dust outlet 170 is opened simultaneously.

[0037] The filter plate 750 is detachably installed inside the ash storage box 710, dividing the ash storage box 710 into a first chamber 711 and a second chamber 712. The dust outlet 170, support frame 720, and second cylinder 730 are located in the first chamber 711. One end of the connecting pipe 760 is connected to the second chamber 712, and the other end is connected to the air outlet pipe 150. A control valve 770 is installed on the connecting pipe 760. When the dust outlet 170 is opened, the control valve 770 simultaneously opens the connecting pipe; when the dust outlet 170 is closed, the control valve 770 simultaneously closes the connecting pipe.

[0038] A door is provided on the ash storage box 710, and the door is connected to the first chamber 711. The ash storage box 710 can be cleaned periodically through the door.

[0039] A material collection hopper 180 is formed at the lower end of the housing 100, and a discharge port is formed at the end of the material collection hopper 180. A dust removal cover 181 is provided at the discharge port.
