Description

Technical Field

[0001] The present invention relates to the technical field of fabric dust removal, and in particular to high-efficiency dust removal equipment for composite fabric processing and a process thereof. Background Art

[0002] Composite fabrics are easily contaminated by fiber debris, environmental dust, etc. during the processing process. Traditional dust removal equipment mostly uses one-sided air jets or mechanical beating methods, which have problems such as incomplete cleaning and low efficiency. In particular, high-precision composite fabrics (such as bulletproof fibers and functional coated fabrics) have strict requirements on surface cleanliness, and conventional equipment is difficult to effectively remove micron-sized particles embedded in the fiber gaps. In the existing technology, the dust collection system mostly relies on a single negative pressure source, which is prone to suction attenuation due to filter bag clogging, and lacks real-time monitoring methods. Maintenance relies on manual inspections, which can easily cause downtime delays. In addition, the double-sided synchronous dust removal design is not yet mature, and some equipment uses flipping and repeated processing methods, which increases the risk of secondary contamination of the fabric surface.

[0003] The current dust removal process generally adopts a fixed parameter operation mode and cannot be dynamically adjusted according to the fabric type or dust load. For example, the rigid setting of the jet pressure and impact frequency causes energy waste in low-dust conditions, while in high-dust conditions, the dust removal does not meet the standards due to insufficient processing capacity. Existing pressure monitoring devices mostly use electronically controlled sensors to directly detect the status of the filter bags, but they are prone to failure due to high temperature and high humidity environments, and cannot convert the pressure signal into mechanical linkage control. At the same time, the filter bag replacement process is cumbersome, and the traditional locking structure requires special tools to disassemble, which seriously affects production efficiency. The market is in urgent need of a dust removal solution that can integrate double-sided processing, intelligent adjustment and rapid maintenance to meet the urgent needs of the composite fabric processing industry for efficiency and intelligence; therefore, we propose a high-efficiency dust removal equipment and process for composite fabric processing to solve this problem.

[0017] The present invention also provides a high-efficiency dust removal process for composite fabric processing, which is applied to the above-mentioned high-efficiency dust removal equipment for composite fabric processing, and includes the following steps:

[0018] S1: The composite fabric passes through the upper installation frame, two guide wheels and the lower installation frame in sequence. Under the action of the reset spring, the two conveying motors are started to drive the conveying wheels to rotate. The conveying wheels realize the conveying of the fabric in cooperation with the positioning wheels.

[0019] S2: Start the fan and set the fan output power to 2.2-3.0kW, corresponding to an air velocity of 18-25m / s at the nozzle outlet. The air is introduced into the jet frame and then ejected from multiple nozzles to blow the dust on the fabric downwards.

[0020] S3: Start the drive motor to drive the drive shaft to rotate, and the speed is set to 800-1200rpm. The drive shaft drives the beating wheel to rotate, thereby beating the surface of the fabric, shaking off the dust adhering to the fabric, and blowing the dust downward through the air ejected from the air nozzle, and falling into the dust collection box;

[0021] S4: The driving shaft drives the active pulley to rotate, and accelerates the rotation of the driven pulley and the drum through the belt pulley, so that the rotation speed of the drum is 1600-2400rpm. The rotation of the drum drives the fan blades to rotate, thereby generating wind force in the drum and generating negative pressure in the dust collection pipe, which guides the dust in the dust collection box into the curved pipe and then into the filter bag through the dust collection hopper, and the dust is filtered and collected by the filter bag;

[0022] S5. When the air containing dust enters the filter bag through the dust hopper, the air pressure in the filter bag increases, and the lower piston plate is pushed upward under the action of the air pressure, so that the liquid in the first cavity enters the second cavity through the connecting pipe, and drives the upper piston plate to move upward. As the dust in the filter bag accumulates, the pressure in the filter bag increases, and continues to drive the upper and lower piston plates to move upward. When the upper piston plate abuts against the touch button, it means that enough dust has accumulated in the filter bag, resulting in excessive filtration resistance. At this time, the controller controls the alarm to start, thereby issuing an alarm message to remind the staff to clean the filter bag. The staff manually rotates the two rotating columns to disengage the baffle from the dust hopper, then removes the filter cartridge and the filter bag from the filter cartridge so that it can be replaced.

[0023] S6. When the liquid flows through the connecting pipe, the spiral blade is pushed to drive the connecting pipe to rotate, and the connecting pipe drives multiple L frames and slides to perform circular motion. The slide moves outward under the action of centrifugal force, and drives the sliding frame to move downward through sliding cooperation with the inclined rod. The sliding frame drives the lifting ring to move downward, so that the lifting ring squeezes the pressure sensor. When the dust accumulation speed in the dust filter increases, the upward movement speed of the lower piston plate and the upper piston plate will increase, thereby increasing the liquid circulation speed in the connecting pipe, thereby increasing the squeezing force of the pressure sensor, and the pressure sensor can reflect the dust accumulation speed in the filter bag. When the pressure value monitored by the pressure sensor is greater than 1.8kPa, the fan power increases by 20%-30%, the output speed of the conveying motor is reduced to 70%-80% of the original speed, and the output speed of the drive motor is increased by 20%-25%; when the pressure monitored by the pressure sensor is less than 0.7kPa: the fan power is reduced to 80% of the base value, the output speed of the conveying motor is increased to 120% of the original speed, and the output speed of the drive motor is reduced by 15%-20%.

[0024] Compared with the prior art, the present invention provides a high-efficiency dust removal device and process for composite fabric processing, which has the following beneficial effects:

[0025] (1) Automatic dust removal of composite fabric dust can be achieved by cooperating with the conveying mechanism, the jet mechanism, the striking mechanism, the dust suction mechanism and the filtering mechanism. By arranging the above mechanisms into two groups, the dust on the two sides of the fabric can be processed separately, thereby achieving thorough dust removal.

[0026] (2) The positive pressure monitoring mechanism can monitor the pressure inside the filter bag and reflect it to the movement of the upper piston plate. When the pressure is large enough, the touch button is triggered and the controller alarm is activated to achieve the effect of reminding maintenance. The convenience of filter bag replacement is improved by the cooperation of the rotating column and the baffle.

[0027] (3) When the pressure value monitored by the pressure sensor increases, the controller controls the output power of the fan to increase, the output speed of the conveying motor to decrease, and the output speed of the drive motor to increase, thereby reducing the rotation speed of the conveying wheel to reduce the conveying speed of the fabric, increasing the jet speed of the jet nozzle, and increasing the rotation speed of the striking wheel and the fan blades, thereby improving the dust absorption effect when the fabric contains a lot of dust. Conversely, when the pressure value monitored by the pressure sensor decreases, the controller controls the output power of the fan to decrease, the output speed of the conveying motor to increase, and the output speed of the drive motor to decrease, thereby improving the fabric processing efficiency and avoiding waste of resources;

[0028] (4) Through the coordinated action of multiple mechanisms, the dust on the surface of the composite fabric is removed in an all-round and efficient manner. The equipment adopts an air jet mechanism and a dust suction mechanism that are symmetrically distributed above and below, combined with a double-sided striking and negative pressure adsorption design, which can simultaneously perform independent dust removal on the front and back of the fabric, significantly improving the cleaning effect. The integrated positive pressure monitoring mechanism senses the pressure changes inside the filter bag in real time, and triggers maintenance alarms through the dual mechanisms of mechanical linkage and electronic feedback to ensure that the filtration system is always in the best working condition. In addition, the set linkage mechanism can intelligently optimize the dust removal parameters based on the dust accumulation rate, while ensuring the dust removal efficiency. A precise balance between energy consumption and processing speed is achieved, solving the problem of resource waste caused by the fixed working mode of traditional equipment, and significantly improving the degree of automation and process adaptability.

[0062] The present invention also provides a high-efficiency dust removal process for composite fabric processing, which is applied to the above-mentioned high-efficiency dust removal equipment for composite fabric processing, and includes the following steps:

[0063] S1: The composite fabric passes through the upper mounting frame 201, the two guide wheels 9 and the lower mounting frame 201 in sequence. Under the action of the return spring 206, the two conveying motors 203 are started to drive the conveying wheel 202 to rotate. The conveying wheel 202 realizes the conveying of the fabric in cooperation with the positioning wheel 205.

[0064] S2: Start the fan 303 and set the output power of the fan 303 to 3.0kW, which corresponds to a wind speed of 25m / s at the outlet of the air nozzle 302. The air is introduced into the air injection frame 301 and then ejected from the multiple air nozzles 302 to blow the dust on the fabric downwards.

[0065] S3: The drive motor 401 is started to drive the drive shaft 403 to rotate at a speed of 1000 rpm. The drive shaft 403 drives the beating wheel 402 to rotate, thereby beating the surface of the fabric, shaking off the dust adhering to the fabric, and blowing the dust downward through the air ejected from the air nozzle 302, and dropping it into the dust collection box 10;

[0066] S4: The driving shaft 403 drives the active pulley 404 to rotate, and accelerates the rotation of the driven pulley 405 and the drum 503 through the belt pulley, so that the rotation speed of the drum 503 is 2000 rpm. The rotation of the drum 503 drives the fan blades 504 to rotate, thereby generating wind force in the drum 503 and generating negative pressure in the dust collection pipe 505, which guides the dust in the dust collection box 10 into the curved pipe 502 and then into the filter bag 602 through the dust collection hopper 501, and the dust is filtered and collected by the filter bag 602;

[0067] When the dust-laden air enters the filter bag 602 through the dust hopper 501, the air pressure in the filter bag 602 increases, and the lower piston plate 706 is pushed upward by the air pressure, so that the liquid in the first cavity enters the second cavity through the connecting pipe 808, and drives the upper piston plate 707 to move upward. As the dust in the filter bag 602 accumulates, the pressure in the filter bag 602 increases, and continues to drive the upper piston plate 707 and the lower piston plate 706 to move upward. When the upper piston plate 707 abuts against the touch button 705, it indicates that a sufficient amount of dust has accumulated in the filter bag 602, resulting in excessive filtration resistance. At this time, the controller 11 controls the alarm 12 to start, thereby issuing an alarm message to remind the staff to clean the filter bag 602. The staff manually rotates the two rotating columns 603 to disengage the baffle 605 from the dust hopper 501, and then removes the filter cartridge 601 and the filter bag 602 from the filter cartridge 601 so that it can be replaced.

[0068] S6. When the liquid flows through the connecting pipe 808, the spiral blade 809 is pushed to drive the connecting pipe 808 to rotate. The connecting pipe 808 drives multiple L frames 804 and the slide plate 805 to perform circular motion. The slide plate 805 moves outward under the action of centrifugal force, and drives the sliding frame 803 to move downward by sliding with the inclined rod 806. The sliding frame 803 drives the lifting ring 801 to move downward, so that the lifting ring 801 squeezes the pressure sensor 802. When the dust accumulation speed in the dust filter increases, the speed of the lower piston plate 706 and the upper piston plate 707 moving upward will increase, thereby increasing the liquid circulation speed in the connecting pipe 808. When the pressure value detected by the pressure sensor 802 is greater than 1.8 kPa, the power of the fan 303 is increased by 25%, the output speed of the conveying motor 203 is reduced to 75% of the original speed, and the output speed of the drive motor 401 is increased by 25%; when the pressure detected by the pressure sensor 802 is less than 0.7 kPa: the power of the fan 303 is reduced to 80% of the basic value, the output speed of the conveying motor 203 is increased to 120% of the original speed, and the output speed of the drive motor 401 is reduced by 20%.

[0069] In this embodiment, automatic dust removal of composite fabric dust can be achieved through the cooperation of the conveying mechanism 2 with the jet mechanism 3, the striking mechanism 4, the dust suction mechanism 5 and the filtering mechanism 6, and by setting the above mechanisms into two groups, the dust on the two sides of the fabric can be treated separately, thereby achieving thorough dust removal. The positive pressure monitoring mechanism 7 can monitor the pressure in the filter bag 602 and reflect it on the movement of the upper piston plate 707. When the pressure is large enough, the touch button 705 is triggered and the controller 11 alarm 12 is started to achieve the effect of reminding maintenance. The convenience of replacing the filter bag 602 is improved by setting the cooperation between the rotating column 603 and the baffle 605. When the pressure is monitored by the pressure sensor 802, the pressure When the value increases, the controller 11 controls the output power of the fan 303 to increase, the output speed of the conveying motor 203 to decrease, and the output speed of the drive motor 401 to increase, thereby reducing the rotation speed of the conveying wheel 202 to reduce the conveying speed of the fabric, increasing the jet speed of the air nozzle 302, and at the same time increasing the rotation speed of the striking wheel 402 and the fan blade 504, thereby improving the dust absorption effect when the dust content of the fabric is high. Conversely, when the pressure value monitored by the pressure sensor 802 decreases, the controller 11 controls the output power of the fan 303 to decrease, the output speed of the conveying motor 203 to increase, and the output speed of the drive motor 401 to decrease, thereby improving the fabric processing efficiency and avoiding waste of resources.

8. A high-efficiency dust removal process for composite fabric processing, applied to the high-efficiency dust removal equipment for composite fabric processing according to claim 7, characterized in that: The following steps are involved: S1: The fabric is passed through the upper mounting frame (201), the two guide wheels (9) and the lower mounting frame (201) in sequence, and the two conveying motors (203) are started to drive the conveying wheels (202) to rotate under the action of the return spring (206). The conveying wheels (202) convey the fabric in cooperation with the positioning wheels (205); S2: Start the fan (303), set the output power of the fan (303) to 2.2-3.0kW, and the corresponding air velocity at the outlet of the air nozzle (302) to 18-25m / s, introduce air into the air jet frame (301), and then eject air from the multiple air nozzles (302) to blow the dust on the fabric downward; S3: Starting the driving motor (401) to drive the driving shaft (403) to rotate, the speed is set to 800-1200 rpm, the driving shaft (403) drives the beating wheel (402) to rotate, thereby beating the surface of the fabric, shaking off the dust adhering to the fabric, and blowing the dust downward through the air ejected from the air nozzle (302), and dropping it into the dust collection box (10); S4: The driving shaft (403) drives the driving pulley (404) to rotate, and accelerates the rotation of the driven pulley (405) and the rotating drum (503) through the belt pulley, so that the rotating drum (503) rotates at a speed of 1600-2400 rpm. The rotating drum (503) drives the fan blades (504) to rotate, thereby generating wind force in the rotating drum (503) and generating negative pressure in the dust collection pipe (505), so that the dust in the dust collection box (10) is introduced into the curved pipe (502), and then introduced into the filter bag (602) through the dust collection hopper (501), and the dust is filtered and collected by the filter bag (602); S5. When the air with dust enters the filter bag (602) through the dust hopper (501), the air pressure in the filter bag (602) increases, and the lower piston plate (706) is pushed upward by the air pressure, so that the liquid in the first cavity enters the second cavity through the connecting pipe (808), and drives the upper piston plate (707) to move upward. As the dust in the filter bag (602) accumulates, the pressure in the filter bag (602) increases, and continues to drive the upper piston plate (707) and the lower piston plate (706) to move upward. When the upper piston plate ( When the filter bag (602) is in contact with the touch button (707), it indicates that a sufficient amount of dust has accumulated in the filter bag (602), resulting in excessive filtration resistance. At this time, the controller (11) controls the alarm (12) to start, thereby issuing an alarm message to remind the staff to clean the filter bag (602). The staff manually rotates the two rotating columns (603) to disengage the baffle (605) from the dust hopper (501), and then removes the filter cartridge (601) and takes the filter bag (602) out of the filter cartridge (601) so that it can be replaced. S6. When the liquid flows through the connecting pipe (808), the spiral blade (809) is pushed to drive the connecting pipe (808) to rotate. The connecting pipe (808) drives the multiple L frames (804) and the slide plate (805) to perform circular motion. The slide plate (805) moves outward under the action of centrifugal force and drives the sliding frame (803) to move downward by sliding with the inclined rod (806). The sliding frame (803) drives the lifting ring (801) to move downward, so that the lifting ring (801) squeezes the pressure sensor (802). When the dust accumulation speed in the dust filter increases, the speed of the lower piston plate (706) and the upper piston plate (707) moving upward will increase, thereby increasing the liquid circulation speed in the connecting pipe (808). The force with which the pressure sensor (802) is squeezed increases, so that the speed of dust accumulation in the filter bag (602) can be reflected through the pressure sensor (802). When the pressure value monitored by the pressure sensor (802) is greater than 1.8 kPa, the power of the fan (303) is increased by 20%-30%, the output speed of the conveying motor (203) is reduced to 70%-80% of the original speed, and the output speed of the drive motor (401) is increased by 20%-25%. When the pressure monitored by the pressure sensor (802) is less than 0.7 kPa: the power of the fan (303) is reduced to 80% of the base value, the output speed of the conveying motor (203) is increased to 120% of the original speed, and the output speed of the drive motor (401) is reduced by 15%-20%.
