Description

Technical Field

[0001] This invention belongs to the field of air filtration technology, and in particular relates to a dust-laden exhaust gas purification device for a high-efficiency self-cleaning textile fabric winding device. Background Technology

[0002] Textile fabric winding devices are key equipment at the end of textile production. They are used to neatly wind up fabrics after weaving, dyeing and other processes, making them convenient for storage, transportation and subsequent processing. During the winding process, efficient self-cleaning is required to remove residual short fibers, thread ends and dust particles, so as to avoid these contaminants from affecting the smoothness and performance of the fabric, and to avoid defects in the textile fabric during the winding process, thereby improving the quality of the textile fabric leaving the factory.

[0003] Currently, most textile fabric cleaning methods use high-speed airflow to remove impurities adhering to the fabric surface, which continuously generates dust-laden exhaust gas. This dust-laden exhaust gas mainly consists of foreign matter such as short fibers, fine threads, and dust particles mixed in with the air. Therefore, it is necessary to filter and purify the dust-laden exhaust gas to avoid adverse effects on the textile production environment and the health of workers. However, existing dust-laden exhaust gas purification equipment has a relatively simple structure. As the usage time increases, a large amount of foreign matter accumulates in the filter element, which can clog the filter channel. This requires frequent shutdowns for cleaning, affecting the efficiency of dust-laden exhaust gas purification and increasing the frequency of downtime maintenance for the dust-laden exhaust gas purification equipment, thereby increasing the labor intensity of workers.

[0004] Therefore, a dust-laden exhaust gas purification device for a high-efficiency self-cleaning textile fabric winding device is proposed to solve the above problems. Summary of the Invention

[0012] In the aforementioned dust-laden exhaust gas purification equipment for a high-efficiency self-cleaning textile fabric winding device, the self-cleaning auxiliary mechanism includes a pressure box fixedly connected to the outer wall of a rectangular purification box. An air pump is fixedly connected to the upper surface of the pressure box. A conveying pipe is fixedly connected to the inlet end of the air pump. The inlet end of the conveying pipe passes sequentially through the inner wall of the rectangular purification box and the lower surface of the partition plate. The inlet end of the conveying pipe communicates with the internal cavity of the composite filter cartridge.

The bottom outer wall of the pressure chamber is fixedly connected to a pressure solenoid valve, the outlet of which is fixedly connected to a return pipe. The outlet of the return pipe passes through the bottom of the metal shell and communicates with the right-side cavity of the metal shell.

[0013] In the aforementioned dust-laden exhaust gas purification equipment for a high-efficiency self-cleaning textile fabric winding device, an electric heating tube is fixedly embedded in the side wall of the pressure box, a metal mesh cylinder is fixedly sleeved on the tube wall of the electric heating tube, and an installation hole is opened in the tube wall of the return pipe, with a temperature sensor fixedly connected to the wall of the installation hole.

[0014] In the dust-laden exhaust gas purification equipment for the high-efficiency self-cleaning textile fabric winding device described above, two symmetrically distributed fixing frames are fixedly connected to the bottom end of the rectangular purification box, and a handle is fixedly connected to the lower surface of the sealing cover.

[0015] In the dust-laden exhaust gas purification equipment for the high-efficiency self-cleaning textile fabric winding device described above, through holes are provided at the four corners of the upper surface of the sealing cover, and bolts are connected to the hole walls of the through holes. Threaded blind holes that mate with the bolts are provided on the upper surface of the metal shell.

[0016] Compared with existing technologies, the advantages of the dust-laden exhaust gas purification equipment for high-efficiency self-cleaning textile fabric winding devices are:

[0017] 1. Through the established thickness detection mechanism, static elimination component, and air pump, when the textile fabric needs to be cleaned of attached impurities (short fibers, fine threads, and dust particles) before being wound by the winding device, the textile fabric is first connected to the dust-laden exhaust gas purification equipment. As the textile fabric passes through the positioning conductive rod and the movable conductive rod, the positioning conductive rod and the movable conductive rod discharge static electricity from both sides of the textile fabric. After static electricity elimination, the adhesion of foreign objects on the surface of the textile fabric is reduced, and it is convenient for the subsequent blowing and cleaning of foreign objects. In addition, the thickness detection mechanism can also detect the thickness of the textile fabric. The detected textile fabric thickness can also be linked to the air pump's suction power, so that the air pump's suction power can be automatically adjusted proportionally to the textile fabric thickness. This mechanism enables the dust-laden exhaust gas purification equipment to have the functions of textile fabric thickness measurement and static electricity elimination, which not only improves the cleaning effect and convenience of textile fabric, but also enables the dust-laden exhaust gas purification equipment to have the ability to automatically adjust the air pump's suction power proportionally to the textile fabric thickness, thereby improving the energy-saving performance of the equipment.

[0018] 2. Through the installation of a metal protective filter cartridge, a fabric cleaning mechanism, and a composite filter cartridge, the air pump circulates the air inside the equipment. The dust-laden exhaust gas entering from the left side of the metal casing is treated by the metal protective filter cartridge and the composite filter cartridge to form clean air. The clean air then blows away the adhering material from the surface of the textile fabric through the fabric cleaning mechanism. Moreover, the textile fabric is cleaned twice by the clean air as it passes through the metal casing. During the air circulation process, it is also heated by an electric heating tube. The heated air further increases the molecular activity at the contact point between foreign objects and the textile fabric, thereby reducing adhesion and improving the cleaning effect. This mechanism enables the dust-laden exhaust gas purification equipment to have the function of filtering and purifying dust-laden exhaust gas. Furthermore, the purified clean air can also perform double self-cleaning on the textile fabric, improving the self-cleaning effect of the textile fabric.

[0019] 3. Through the self-cleaning auxiliary mechanism, as the usage time increases, when the mesh of the metal protective filter cartridge becomes clogged with large foreign objects such as short fibers and small wire ends, interfering with airflow, the wind pressure detected by the wind pressure sensor at the delivery pipe decreases. The PLC controller controls the air pump to stop working. Because the pressure box does not receive clean air replenishment, the internal air pressure of the pressure box is lower than the preset pressure of the pressure solenoid valve, and the pressure solenoid valve closes. At the same time, the PLC controller also controls the normally closed solenoid valve to be energized. After the normally closed solenoid valve opens, the high-pressure air remaining in the pressure box is quickly discharged into the space between the composite filter cartridge and the metal protective filter cartridge through the normally closed solenoid valve and the air inlet pipe for backflushing and cleaning of large foreign objects. Then, the PLC controller controls the air pump to work again, and the normally closed solenoid valve closes. Because the metal protective filter cartridge has been backflushed and cleaned, the wind pressure in the delivery pipe reaches the required level again. This mechanism enables the dust-laden waste gas purification equipment to have a short-term self-cleaning function for foreign objects on the surface of the metal protective filter cartridge, reducing the frequency of equipment downtime maintenance and reducing the labor intensity of the staff.

[0030] A thickness detection mechanism 6 is fixedly connected to the inner wall of the metal housing 51. The thickness detection mechanism 6 includes a positioning conductive rotating rod 61 and a movable conductive rotating rod 62. The two ends of the positioning conductive rotating rod 61 are connected to the inner wall of the metal housing 51 through rolling bearings.

The outer wall of the U-shaped strip 63 is in movable contact with the inner wall of the metal housing 51.

[0032] A PLC controller 13 and a self-cleaning auxiliary mechanism 8 are fixedly connected to the outer wall of the rectangular purification box 1. The self-cleaning auxiliary mechanism 8 includes a pressure box 81 fixedly connected to the outer wall of the rectangular purification box 1. An air pump 82 is fixedly connected to the upper surface of the pressure box 81. The air inlet end of the air pump 82 is fixedly connected to a delivery pipe 83.

[0033] An electric heating tube 9 is fixedly embedded in the side wall of the pressure box 81. A metal mesh tube 14 is fixedly sleeved on the wall of the electric heating tube 9. An installation hole is opened in the wall of the return pipe 89, and a temperature sensor 15 is fixedly connected to the wall of the installation hole. By increasing the temperature, the molecular activity at the contact position between the foreign object and the textile fabric is accelerated, thereby improving the convenience of blowing away the foreign object.

[0034] Two symmetrically distributed mounting brackets 16 are fixedly connected to the bottom of the rectangular purification box 1. A handle 17 is fixedly connected to the lower surface of the sealing cover 3. The laser rangefinder 66, wind pressure sensor 84, and temperature sensor 15 are all electrically connected to the input terminal of the PLC controller 13 through wires. The air pump 82, normally closed solenoid valve 86, and electric heating tube 9 are all electrically connected to the output terminal of the PLC controller 13 through wires. The pressure solenoid valve 88 is electrically connected to the power supply through the PLC controller 13. The above-mentioned electrical components and connections are existing technology and will not be described in detail here.

[0035] The operating principle of the present invention is described as follows: When the textile fabric needs to be cleaned of attached impurities (short fibers, fine thread ends and dust particles) before being wound by the winding device, the dust-containing exhaust gas purification equipment is first installed at the textile fabric winding device by the fixing frame 16, and the fabric outlet of the metal shell 51 is located at the inlet of the textile fabric winding device.

[0036] Then open the sealing cover 52 and pass the side end of the textile fabric through the inlet of the metal housing 51, the thickness detection mechanism 6, the U-shaped hollow plate 55, the partition frame 53 and the outlet of the metal housing 51 in sequence. Finally, connect the side end of the textile fabric to the winding roller of the textile fabric winding device (this side end has been cleaned in advance). Then close the sealing cover 52 and limit the sealing cover 52 and the metal housing 51 with bolts 18.

[0037] When the winding roller of the textile fabric winding device drives the textile fabric to wind up, the textile fabric first passes through the positioning conductive rotating rod 61 and the movable conductive rotating rod 62. After the two roll on the textile fabric, they can discharge the static electricity generated on the textile fabric due to production friction. The static electricity is then introduced into the factory grounding facility through the metal shell 51, the conductive wire 71, and the fixed iron ring 72. The fixed iron ring 72 can be fixed to the grounding facility by metal screws. After the static electricity of the textile fabric is eliminated, the adhesion of foreign objects on the surface of the textile fabric can be reduced, and it is convenient for the foreign objects to be blown away and cleaned in the future.

[0038] Furthermore, when the textile fabric passes through the positioning conductive rod 61 and the movable conductive rod 62, the PLC controller 13 controls the air pump 82 and the electric heating tube 9 to work. The thickness of the textile fabric also compresses the movable conductive rod 62, causing it to move downwards. The movable conductive rod 62 drives the U-shaped strip 63 downwards and compresses the return spring 65 at the limiting protrusion 64, causing the return spring 65 to generate a restoring force. This restoring force pushes the U-shaped strip 63 back, ensuring that the movable conductive rod 62 at the U-shaped strip 63 is tightly pressed against the underside of the textile fabric, thus ensuring the textile fabric... The device effectively discharges static electricity from the fabric and also assists in the accurate measurement of the fabric thickness. During device initialization, when non-woven fabric passes through, the laser rangefinder 66 emits a laser pulse. The laser pulse is reflected by the bottom of the U-shaped strip 63 and received by the laser rangefinder 66. The distance H1 between the measuring end of the laser rangefinder 66 and the U-shaped strip 63 is calculated using the speed of light and the time difference of the laser pulse's round trip. After the U-shaped strip 63 moves down, the laser rangefinder 66 measures the distance H1 between the measuring end of the laser rangefinder 66 and the bottom of the U-shaped strip 63 again. The distance H2 is measured by the laser rangefinder 66. Each detection result is sent to the PLC controller 13 as an electrical signal. The PLC controller 13 calculates the difference between the distances H1 and H2, which is the thickness of the textile fabric. At the same time, the PLC controller 13 adjusts the suction power of the air pump 82 proportionally according to the thickness of the textile fabric. The thicker the textile fabric, the greater the suction power of the air pump 82, and the greater the flow rate of the clean air sprayed onto the textile fabric. This makes the clean air more effective in cleaning foreign objects hidden inside the thick textile fabric. If the textile fabric is thin, the suction power of the air pump 82 is reduced. At this time, the foreign objects attached to the textile fabric mainly accumulate on the surface, which is easy to clean. Thus, the reduced power of the air pump 82 can achieve the energy-saving effect of the equipment. This mechanism enables the dust-containing waste gas purification equipment to have the functions of measuring the thickness of the textile fabric and eliminating static electricity. It not only improves the cleaning effect and convenience of the textile fabric, but also enables the dust-containing waste gas purification equipment to automatically adjust the suction power of the air pump 82 proportionally with the thickness of the textile fabric, thereby improving the energy-saving performance of the equipment.

[0039] Furthermore, during the internal cavity circulation process of the dust-laden exhaust gas purification equipment, the electric heating tube 9 also operates according to the heating power preset by the PLC controller 13, increasing the temperature of the clean air in the pressure box 81. The temperature value is monitored by the temperature sensor 15 and meets the preset requirements. Then, when the clean air with heat blows away impurities from the textile fabric, the heat can increase the molecular activity between the impurities and the textile fabric, making it easier for foreign objects to be blown away by the clean air flow, thus improving the cleaning effect of the textile fabric. The temperature sensor 15 can detect the temperature of the circulating air in real time. If the temperature exceeds the temperature threshold preset by the PLC controller 13, the PLC controller 13 will appropriately reduce the heating power of the electric heating tube 9 to avoid the clean air temperature being too high and damaging the textile fabric.

[0040] The air pump 82 draws clean air filtered and purified by the composite filter cartridge 11 from the rectangular purification box 1 through the delivery pipe 83. The clean air is injected into the pressure box 81 through the one-way valve 85. As the amount of clean air in the pressure box 81 increases, the internal air pressure of the pressure box 81 rises. When the air pressure in the pressure box 81 rises to the preset pressure range of the pressure solenoid valve 88, the pressure solenoid valve 88 automatically opens, and the excess air in the pressure box 81 is transported to the right side of the metal shell 51 through the return pipe 89. At this time, because the air pump 82 continues to supply clean air, the pressure inside the pressure box 81 is still maintained within the preset pressure range of the pressure solenoid valve 88. Then, the clean air on the right side of the metal shell 51 is injected into the U-shaped hollow plate 55 through multiple pipes 57. Then, the clean air is sprayed onto the textile fabric to be rolled up through the jet hole 56. The clean air has a strong impact force when it is sprayed out, and the top and bottom of the U-shaped hollow plate 55 simultaneously spray clean air streams, realizing double-sided self-cleaning of the textile fabric. The clean air stream blows away the textile fabric. Foreign matter adhering to the fabric surface is then carried by clean air to form dusty exhaust gas. The dusty exhaust gas enters the rectangular purification box 1 through a one-way air guide pipe 58. Large foreign matter such as short fibers and fine threads in the dusty exhaust gas is then intercepted by the metal protective filter cartridge 4, while small foreign matter such as dust particles is intercepted by the composite filter cartridge 11. Finally, the air passing through the composite filter cartridge 11 forms clean air again, which is then drawn in by the air pump 82. Ultimately, the textile fabric undergoes static electricity removal and primary cleaning of foreign matter on the left side of the metal housing 51, and then undergoes secondary cleaning of the textile fabric on the right side of the metal housing 51 with clean air, improving the cleaning effect of the textile fabric. The cleaned textile fabric enters the winding equipment directly through the outlet of the metal housing 51 for winding, minimizing the possibility of secondary pollution caused by the textile fabric being exposed to the outside. This mechanism enables the dusty exhaust gas purification equipment to have the function of dusty exhaust gas filtration and purification, and the purified clean air can also perform double self-cleaning on the textile fabric, improving the self-cleaning effect of the textile fabric.

[0041] As usage time increases, the mesh of the metal protective filter cartridge 4 becomes clogged with large foreign objects such as short fibers and small wire ends, interfering with airflow. At this time, the air pressure detected by the air pressure sensor 84 at the delivery pipe 83 decreases, and the air pressure sensor 84 sends the detection result to the PLC controller 13. If the air pressure detected by the air pressure sensor 84 is lower than the preset air pressure threshold of the PLC controller 13, the PLC controller 13 controls the air pump 82 to stop working. Because the pressure tank 81 does not receive clean air replenishment, the internal air pressure of the pressure tank 81 falls below the preset pressure of the pressure solenoid valve 88, and the pressure solenoid valve 88 closes. Simultaneously, the PLC controller 13 also controls the normally closed solenoid valve 86 to be energized (e.g., the energization time is preset to 2 seconds). After the normally closed solenoid valve 86 opens, the pressure tank 8... The high-pressure air remaining in the chamber 1 is quickly discharged into the space between the composite filter cartridge 11 and the metal protective filter cartridge 4 through the normally closed solenoid valve 86 and the air inlet pipe 87. The pulsed air can clean large foreign objects attached to the surface of the metal protective filter cartridge 4 in reverse. Then, the PLC controller 13 controls the air pump 82 to restart and simultaneously controls the normally closed solenoid valve 86 to close. Since the metal protective filter cartridge 4 has completed backflushing cleaning, the air pressure in the delivery pipe 83 returns to the required value. Finally, after long-term use of the dust-containing waste gas purification equipment, the staff needs to open the sealing cover 3 to thoroughly clean the foreign objects inside the rectangular purification box 1. This mechanism enables the dust-containing waste gas purification equipment to have a short-term self-cleaning function for foreign objects on the surface of the metal protective filter cartridge 4, reducing the frequency of equipment downtime maintenance and reducing the labor intensity of the staff.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
