Description

Technical Field

[0001] This invention belongs to the field of exhaust dust removal technology, and in particular relates to an exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics. Background Technology

[0002] Breathable and moisture-wicking composite textile fabrics are made of multiple materials through a special process, combining excellent breathability and moisture permeability. They allow the skin to breathe freely and quickly wick away sweat, making them widely used in sportswear, outdoor equipment, and other fields. After wet processing steps such as dyeing and washing, breathable and moisture-wicking composite textile fabrics need to be dried to prevent residual moisture from causing mold growth and affecting the quality of the fabric. Furthermore, dust removal equipment is required during the drying process to treat the exhaust gases and ensure the cleanliness of the working environment. For example, patent CN113654328B discloses a dust removal and drying device for textile fabrics.

[0003] The dust removal devices currently used for drying exhaust gas from breathable and moisture-permeable composite textile fabrics have the following problems during use:

[0004] Lacking the ability to recover heat and moisture from the humid and hot gases discharged during drying, traditional fabric drying equipment mainly relies on direct heating technology. During operation, the equipment needs to consume a lot of energy to heat the drying gases to meet the heat requirements of fabric drying. However, after the fabric is dried, up to 60% of the heat is directly discarded with the humid and hot gases discharged from the equipment's exhaust vents. This large loss of heat not only leads to a long-term low level of heat utilization of the equipment, but also significantly increases the energy consumption costs of enterprises, which runs counter to the current industry trend of energy conservation and emission reduction. Secondly, the humid and hot gases generated during the drying process contain a large amount of moisture, but due to the lack of an effective moisture recovery mechanism in existing equipment, this moisture is directly discharged into the atmosphere without being utilized, which causes a great waste of water resources and further affects the energy-saving and environmental protection performance of fabric drying processing.

[0005] During the operation of the drying equipment, due to the gaps in the fabric inlet and outlet, heat continuously escapes, causing the surrounding environment to become dry and the temperature to be high. This creates extremely favorable conditions for the generation of static electricity. Static electricity not only causes the dried fabric to attract a large amount of dust, resulting in spots, stains and other defects on the fabric surface, seriously affecting the appearance quality and grade of the fabric and hindering the smooth progress of subsequent processing, but may also cause a fire due to electrostatic discharge, posing a serious threat to personnel safety and company property.

[0006] To address these issues, we propose a drying, exhaust, and dust removal device for breathable and moisture-permeable composite textile fabrics. Summary of the Invention

[0014] In the aforementioned air-permeable and moisture-permeable composite textile fabric drying exhaust dust removal device, the secondary dust removal mechanism includes a purification box fixedly connected to the upper surface of the base plate. The side wall of the purification box has a through hole, and a rubber sleeve is fixedly connected to the wall of the through hole.

[0015] In the aforementioned air-permeable and moisture-permeable composite textile fabric drying, exhaust, and dust removal device, the anti-static mechanism includes a rigid pipe fixedly connected to the top side wall of the purification chamber. An arc-shaped hollow block is fixedly connected to the top of the rigid pipe. Multiple nozzles are fixedly connected to the outer wall of the arc-shaped hollow block. An arc-shaped pipe is fixedly connected to the air inlet end of the rigid pipe. An L-shaped gate is movably connected to the bottom end of the arc-shaped pipe.

The water inlet end of the water inlet pipe extends downwards and into the bottom of the water layer. A humidity sensor is fixedly connected to the upper surface of the L-shaped plate.

[0016] In the above-mentioned air-permeable and moisture-permeable composite textile fabric drying, exhaust and dust removal device, the top of the purification box is provided with an installation hole, and a level gauge for measuring the liquid level of the water layer is fixedly connected to the wall of the installation hole, and a liquid replenishment solenoid valve is fixedly connected to the side wall of the purification box.

[0017] In the above-mentioned air-permeable and moisture-permeable composite textile fabric drying, exhaust and dust removal device, a U-shaped handle is fixedly connected to the outer wall of the fixed threaded cover, and a sealing ring is movably sleeved on the outer wall of the fixed threaded cover.

[0018] Compared with existing technologies, the advantages of a breathable and moisture-permeable composite textile fabric drying exhaust and dust removal device are:

[0019] With its heat recovery and air intake mechanisms, the PLC controller controls the air intake mechanism to operate when the breathable and moisture-permeable composite textile fabric is dried in the fabric drying equipment. The main body of the fabric drying equipment transports the hot and humid gas generated after the fabric is dried to the heat recovery mechanism. The heat in the hot and humid air is transferred through heat pipes to the flowing air drawn in by the air intake mechanism. The flowing air carries the heat back to the main body of the fabric drying equipment for reuse. Since the air entering the main body of the fabric drying equipment carries its own heat, the temperature control components of the main body of the fabric drying equipment automatically adjust the heating power of the main body, reducing the heating power while meeting the air heating requirements, thereby reducing energy consumption. This mechanism enables the exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics to recover heat from the hot and humid gas after the fabric is dried, improving the heat utilization rate during the fabric drying process, significantly reducing the energy consumption costs of enterprises, and aligning with the current industry trend of energy conservation and emission reduction. This improves the energy-saving and environmentally friendly performance of the drying process for breathable and moisture-permeable composite textile fabrics.

[0020] Through the cooling and dust removal mechanism, the humid and hot gas, initially cooled by the heat recovery mechanism, passes through the baffle and enters the cooling and dust removal mechanism. At this time, the PLC controller controls the cooling and dust removal mechanism to work and further cools the initially cooled humid and hot gas. In the low-temperature environment, the moisture uses the dust carried in the humid and hot air as crystal nuclei, condenses on the metal mesh plate, and gradually accumulates into water droplets. Finally, the water droplets fall through the metal mesh plate to the bottom of the heat conduction zone of the primary dust removal box, completing the primary dust removal of the humid and hot gas. During the dust removal process, the heat dissipation side of multiple semiconductor cooling chips will conduct heat to the heat sink, and the heat sink will then transfer the heat to the air flowing in the heat recovery zone at the top of the primary dust removal box, further improving the heat recovery effect and heat utilization rate during the fabric drying process, thereby reducing the energy consumption of fabric drying.

[0021] With the addition of a secondary dust removal mechanism, when humid and hot air carrying water is delivered to the ceramic filter cartridge of the purification chamber through the exhaust pipe, the humid and hot air is subjected to secondary dust removal by the ceramic filter cartridge, while the gas and water pass through the ceramic filter cartridge into the purification chamber. The water is added to the water layer for reuse, and the dust-free, low-temperature air is discharged through the anti-static mechanism. This mechanism enables the exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics to not only have the function of water recovery and reuse, but also the function of secondary dust removal, avoiding the waste of water resources, improving the dust removal effect of the device, further enhancing the energy-saving and environmental protection performance of fabric drying and processing, and improving the reliability of the device.

[0022] With its anti-static mechanism, when the gas discharged into the purification chamber is sprayed out through the nozzles of the anti-static mechanism, the water in the water layer is sprayed onto the surrounding environment of the fabric drying equipment. This prevents static electricity caused by excessively low humidity around the fabric drying equipment. Furthermore, the amount of water entering the anti-static mechanism can be adjusted using a humidity sensor and a miniature waterproof electric push rod. In a dry environment, the more water sprayed out with the gas, the better the anti-drying effect, i.e., the better the anti-static effect. The amount of water entering through the inlet pipe is inversely proportional to the diameter of the air inlet at the arc-shaped pipe, reducing the probability of static electricity buildup around the fabric drying equipment. This mechanism gives the device an anti-static function and prevents the dried fabric from adsorbing large amounts of dust, avoiding surface defects and improving the fabric's appearance and grade. It also reduces the probability of fire caused by static electricity, providing efficient protection for personnel safety and company property. Attached Figure Description

This mechanism enables the exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics to have the function of recovering heat from the humid and hot gas after the fabric is dried, improving the heat utilization rate during the fabric drying process, significantly reducing the energy consumption cost of enterprises, and conforming to the current industry trend of energy conservation and emission reduction, thereby improving the energy-saving and environmental protection performance of the drying process of breathable and moisture-permeable composite textile fabrics.

[0035] A cooling and dust removal mechanism 6 is fixedly embedded on the upper surface of the heat insulation plate 11. The cooling and dust removal mechanism 6 includes a heat-conducting metal plate 61 fixedly embedded on the upper surface of the heat insulation plate 11. Multiple metal mesh plates 62 are fixedly connected to the bottom end of the heat-conducting metal plate 61.

[0036] The four supporting legs of the main body 2 of the fabric drying equipment are fixedly connected to a base plate 12. A secondary dust removal mechanism 7 is fixedly connected to the upper surface of the base plate 12. The secondary dust removal mechanism 7 includes a purification box 71 fixedly connected to the upper surface of the base plate 12. The side wall of the purification box 71 has a through hole, and a rubber sleeve 72 is fixedly connected to the wall of the through hole. The inner wall of the rubber sleeve 72 is fixedly connected to the outlet end of the exhaust pipe 57. A ceramic filter cartridge 73 is movably fitted onto the outer wall of the rubber sleeve 72. The ceramic filter cartridge 73 has the ability to trap dust and impurities, and is also effective against water, liquid, and gas. The body does not constitute an obstruction to passage. The side wall of the purification box 71 is provided with a threaded hole, and the wall of the threaded hole is threadedly connected to a fixed threaded cover 74. The inner wall of the fixed threaded cover 74 is fixedly connected to the outer wall of the side end of the ceramic filter cartridge 73. The outer wall of the fixed threaded cover 74 is provided with a countersunk hole, and the wall of the countersunk hole is fixedly connected to a pressure sensor 75.

This not only avoids the waste of water resources, but also improves the dust removal effect of the device.

[0037] An air intake mechanism 8 is fixedly connected to the upper surface of the base plate 12. The air intake mechanism 8 includes a suction fan 81 fixedly connected to the upper surface of the base plate 12. The suction end of the suction fan 81 is fixedly connected to an exhaust pipe 82.

The air outlet end of the air supply pipe 83 is fixedly connected to the air intake end of the fabric drying equipment body 2.

[0038] The top side wall of the secondary dust removal mechanism 7 is fixedly connected to an anti-static mechanism 9. The anti-static mechanism 9 includes a rigid pipe 91 fixedly connected to the top side wall of the purification chamber 71. An arc-shaped hollow block 92 is fixedly connected to the top of the rigid pipe 91. Multiple nozzles 93 are fixedly connected to the outer wall of the arc-shaped hollow block 92. An arc-shaped pipe 94 is fixedly connected to the air inlet end of the rigid pipe 91. An L-shaped gate 95 is movably connected to the bottom end of the arc-shaped pipe 94. A miniature waterproof electric push rod 96 is fixedly connected to the outer wall of the L-shaped gate 95. The fixed end of the electric push rod 96 is fixedly embedded in the inner wall of the purification box 71. The wall of the arc-shaped tube 94 is fixedly connected to the water inlet pipe 97.

A humidity sensor 99 is fixedly connected to the upper surface of the L-shaped plate 3.

If the water level of the water layer 98 is lower than the low water level threshold preset by the PLC controller 4, the PLC controller 4 controls the liquid replenishment solenoid valve 14 to open, and then the external water supply pipe replenishes the water to the purification tank 71. The amount of replenished water is also monitored by the level gauge 13 to prevent excessive water replenishment. A U-shaped handle 15 is fixedly connected to the outer wall of the fixed threaded cover 74, and a sealing ring 16 is movably sleeved on the outer wall of the fixed threaded cover 74.

[0040] The semiconductor cooling chip 63, the suction fan 81, the miniature waterproof electric push rod 96, the alarm 10, and the liquid replenishment solenoid valve 14 are all electrically connected to the output terminal of the PLC controller 4 via wires. The pressure sensor 75 and the humidity sensor 99 are all electrically connected to the input terminal of the PLC controller 4 via wires. The above-mentioned power supply equipment and electrical connections are all existing technologies, and the heat pipe 51 heat conduction technology is also existing technology, which will not be described in detail here.

[0041] The operating principle of this invention is described as follows: When the breathable and moisture-permeable composite textile fabric is dried by the fabric drying equipment, the fabric is first passed through the main body 2 of the fabric drying equipment. Based on the required drying temperature of the fabric, a corresponding drying temperature threshold is set on the control panel of the main body 2. Then, the main body 2 of the fabric drying equipment is started, and simultaneously, the suction fan 81 is started via the PLC controller 4. The suction fan 81 draws air through the extraction pipe 82, the heat recovery zone 54 of the primary dust collector 1, and the activated carbon filter tank 59. Then... The drawn-in air is delivered to the main body 2 of the fabric drying equipment for heating. In order to raise the temperature of the injected air to the preset drying temperature threshold in a short time, the main body 2 of the fabric drying equipment needs to heat the air with high power and high energy consumption. After the air temperature reaches the standard, the air is sprayed out through the pipes and nozzles inside the main body 2 of the fabric drying equipment. The hot airflow is used to dry the damp breathable and moisture-permeable composite textile fabric. The dried hot and humid gas is discharged through the air outlet pipe at the top of the main body 2 of the fabric drying equipment. Moreover, the air is filtered and purified by dust in the activated carbon filter canister 59 to ensure that the air entering the main body 2 of the fabric drying equipment is clean.

[0042] When the hot and humid gas discharged from the main body 2 of the fabric drying equipment is injected into the heat recovery mechanism 5 area of ​​the primary dust removal box 1 through the bent pipe 56, the heat carried by the hot and humid gas is transferred to the bottom of the heat pipe 51 through the metal mesh cover 52, and the hot and humid gas is initially cooled. Specifically, the liquid refrigerant at the bottom of the heat pipe 51 evaporates and absorbs heat. The evaporated refrigerant rises along the internal channel of the heat pipe 51 to the top of the heat pipe 51. However, since the top of the heat pipe 51 is located in the heat recovery zone 54, and the air drawn by the suction fan 81 flows in the heat recovery zone 54, the flowing air comes into contact with the top of the heat pipe 51. During this process, the flowing air cools and liquefies the evaporated refrigerant at the top of the heat pipe 51 into a liquid state. In the liquefaction process, the heat pipe 51 absorbs the heat. Heat is dissipated into the flowing air, and this heat returns to the fabric drying equipment body 2 through the air intake mechanism 8. Since the air entering the fabric drying equipment body 2 carries its own heat, the temperature control component of the fabric drying equipment body 2 will automatically adjust the heating power of the fabric drying equipment body 2. Under the premise of meeting the air heating requirements, the heating power is reduced, thereby reducing energy consumption. This mechanism enables the exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics to have the function of recovering heat from the humid and hot gas after the fabric is dried, improving the heat utilization rate during the fabric drying process, significantly reducing the energy consumption cost of enterprises, and conforming to the current industry trend of energy conservation and emission reduction, thus improving the energy-saving and environmental protection performance of the drying and processing of breathable and moisture-permeable composite textile fabrics.

[0043] The humid gas, initially cooled by the heat recovery mechanism 5, passes through the baffle 55 and enters the cooling and dust removal mechanism 6. At this time, the PLC controller 4 controls multiple semiconductor cooling chips 63 to operate. These chips reduce the temperature of multiple metal mesh plates 62 via the heat-conducting metal plate 61. Furthermore, the initially cooled humid gas is further cooled as it passes through the multiple low-temperature metal mesh plates 62. The low-temperature environment causes the moisture in the humid gas to liquefy into water droplets that fall to the bottom of the primary dust removal box 1. In this low-temperature environment, the moisture, carried by the humid air, is further cooled. Dust particles act as nuclei, condensing on the metal mesh plate 62 and gradually accumulating into water droplets. These droplets eventually fall through the metal mesh plate 62 to the bottom of the heat-conducting zone 53 of the primary dust removal box 1, completing the primary dust removal of the humid and hot gas. During the dust removal process, the heat dissipation sides of the multiple semiconductor cooling chips 63 transfer heat to the heat sink 64, which then transfers the heat to the flowing air in the heat recovery zone 54 at the top of the primary dust removal box 1. This further improves the heat recovery effect during the fabric drying process and enhances the heat utilization rate, thereby reducing the energy consumption of fabric drying.

[0044] When humid, hot air carrying liquid water is delivered to the ceramic filter cartridge 73 of the purification chamber 71 through the exhaust pipe 57, the humid, hot air is further purified by the ceramic filter cartridge 73, while the gas and liquid water pass through the ceramic filter cartridge 73 into the purification chamber 71. The liquid water is added to the liquid water layer 98 for reuse, and the dust-free, low-temperature air is discharged through the anti-static mechanism 9. During this process, the pressure sensor 75 monitors the air pressure inside the ceramic filter cartridge 73 in real time, and the air pressure value is sent to the PLC controller 4 in the form of an electrical signal. If the filtration channel of the ceramic filter cartridge 73 is blocked by dust, reducing the effectiveness of the secondary dust removal, the air pressure inside the ceramic filter cartridge 73 will gradually decrease. The air pressure rises and exceeds the preset alarm air pressure threshold of PLC controller 4. Then, PLC controller 4 controls alarm 10 to sound an alarm. Alarm 10 reminds the staff that there is too much dust and impurities in the ceramic filter cartridge 73 of the purification box 71, which affects the dust removal effect. The ceramic filter cartridge 73 needs to be cleaned and maintained in time. This mechanism enables the exhaust dust removal device for drying breathable and moisture-permeable composite textile fabrics to not only have the function of water recovery and reuse, but also the function of secondary dust removal. This not only avoids the waste of water resources, but also improves the dust removal effect of the device, further enhances the energy-saving and environmental protection performance of fabric drying and processing, and improves the reliability of the device.

[0045] When the gas discharged into the purification chamber 71 is sprayed out through the nozzle 93 of the anti-static mechanism 9, the water in the water layer 98 will be sprayed onto the surrounding environment of the fabric drying equipment body 2 to prevent static electricity caused by excessively low humidity around the fabric drying equipment body 2. Furthermore, the humidity sensor 99 will detect the humidity of the surrounding environment of the fabric drying equipment body 2 in real time and convert the humidity value into an electrical signal, which will be sent to the PLC controller 4. If the humidity sensor 99 detects that the humidity value around the fabric drying equipment body 2 is lower than the preset drying threshold of the PLC controller 4... After the value is measured, the PLC controller 4 controls the extension of the moving end of the miniature waterproof electric push rod 96. The moving end of the miniature waterproof electric push rod 96 pushes the L-shaped gate 95 to block the bottom air inlet of the arc-shaped tube 94. The lower the humidity value detected by the humidity sensor 99, the greater the extension of the moving end of the miniature waterproof electric push rod 96, until the moving end of the miniature waterproof electric push rod 96 is fully extended. At this time, the miniature waterproof electric push rod 96 pushes the L-shaped gate 95 to block three-quarters of the bottom air inlet of the arc-shaped tube 94. At this time, due to the reduction in the diameter of the air inlet of the arc-shaped tube 94... When the gas inside the purification chamber 71 is discharged through the arc-shaped pipe 94, rigid pipe 91, arc-shaped hollow block 92, and nozzle 93, the discharge speed and discharge volume decrease. Simultaneously, the gas inside the purification chamber 71 increases, and the air pressure rises. The increased air pressure at the top of the purification chamber 71 will push down the water in the water layer 98 and discharge it into the arc-shaped pipe 94 through the water inlet pipe 97. The amount of water entering through the water inlet pipe 97 is inversely proportional to the diameter of the air inlet at the air inlet end of the arc-shaped pipe 94. That is, the drier the area around the main body 2 of the fabric drying equipment, the smaller the diameter of the air inlet at the arc-shaped pipe 94, and the larger the amount of water delivered to the water layer 98 by the water inlet pipe 97. The more water enters the arc-shaped tube 94, the more liquid is carried by the gas and finally sprayed around the main body 2 of the fabric drying equipment through the arc-shaped hollow block 92 and nozzle 93. This increases the humidity of the surrounding environment and reduces the probability of static electricity generated around the main body 2 of the fabric drying equipment due to drying. This mechanism gives the device an anti-static function and prevents the dried fabric from absorbing a large amount of dust, thus avoiding defects on the fabric surface, improving the appearance quality and grade of the fabric, and reducing the probability of fire caused by static electricity. This provides efficient protection for personnel safety and company property.

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.
