Description

Technical Field

[0001] The invention belongs to the technical field of exhaust and dust removal, and in particular relates to an exhaust and dust removal device for drying air-permeable and moisture-permeable composite textile fabrics. Background Art

[0002] Breathable and moisture-permeable composite textile fabrics are composited from a variety of materials through a special process. They have good air permeability and moisture permeability, allowing the skin to breathe freely and quickly discharge sweat. They are widely used in sportswear, outdoor equipment and other fields. Breathable and moisture-permeable composite textile fabrics need to be dried after wet processing steps such as dyeing and washing to prevent residual moisture from causing the fabric to mold and affect the quality of the breathable and moisture-permeable composite textile fabrics. In addition, dust removal equipment is required to treat the exhaust gas during drying to ensure the cleanliness of the working environment. For example, the patent with authorization announcement number CN113654328B discloses a textile fabric dust removal and drying device.

[0003] At present, the dust removal device used for drying and exhausting air of breathable and moisture-permeable composite textile fabrics has the following problems during use: Lacking the ability to recycle heat and moisture in the hot and humid gas 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 gas to meet the heat demand for fabric drying. However, after the fabric is dried, up to 60% of the heat is directly discarded with the hot and humid gas discharged from the exhaust hole of the equipment. This large amount of heat loss not only causes the heat utilization rate of the equipment to be at a low level for a long time, but also greatly increases the energy consumption cost of the enterprise, which runs counter to the current industry trend of energy conservation and emission reduction. Secondly, the hot and humid gas generated during the drying process contains a lot of moisture, but because the existing equipment lacks an effective moisture recovery mechanism, this moisture is directly discharged into the atmosphere without being used, which causes a huge waste of water resources and further affects the energy-saving and environmental protection performance of fabric drying processing; During the operation of the drying equipment, due to the gaps between the fabric inlet and outlet, heat continues to overflow, causing the environment around the equipment to become dry and the temperature to be high, creating extremely favorable conditions for the generation of static electricity. Static electricity will not only cause the dried fabric to absorb 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, hindering the smooth progress of subsequent processing links, but may also cause fires due to static electricity discharge, posing a serious threat to personnel safety and corporate property.

[0010] In the above-mentioned drying, exhaust and dust removal device for a breathable and moisture-permeable composite textile fabric, the secondary dust removal mechanism includes a purification box fixedly connected to the upper surface of the bottom plate. A through hole is formed in the side wall of the purification box, and a rubber sleeve is fixedly connected to the hole wall of the through hole.

[0011] In the above-mentioned drying, exhaust and dust removal device for a breathable and moisture-permeable composite textile fabric, the anti-static mechanism includes a rigid pipe fixedly communicated with the top side wall of the purification box.

[0013] In the above-mentioned drying, exhaust and dust removal device for a breathable and moisture-permeable composite textile fabric, 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.

[0014] Compared with the prior art, the advantages of a drying, exhaust and dust removal device for a breathable and moisture-permeable composite textile fabric are as follows: Through the provided heat recovery mechanism and air intake mechanism, when the breathable and moisture-permeable composite textile fabric is dried by the fabric drying equipment, the PLC controller controls the operation of the air intake mechanism. After the hot and humid gas generated after the fabric drying equipment dries the fabric is transported to the heat recovery mechanism, the heat in the hot and humid air is transferred to the flowing air suctioned by the air intake mechanism through the heat pipe. The flowing air carries the heat and returns to the fabric drying equipment main body for reuse. At this time, since the air entering the fabric drying equipment main body has its own heat, the temperature control component of the fabric drying equipment main body will automatically adjust the heating power of the fabric drying equipment main body. On the premise of meeting the air temperature rise requirement, the heating power is reduced, thereby reducing energy consumption. This mechanism enables the breathable and moisture-permeable composite textile fabric drying exhaust dust removal device to have the function of recovering the heat in the hot and humid gas after fabric drying, improving the utilization rate of heat during the fabric drying process, greatly reducing the enterprise's energy consumption cost, and conforming to the current industry trend of energy conservation and emission reduction, improving the energy conservation and environmental protection performance of the breathable and moisture-permeable composite textile fabric drying and processing.

[0015] Through the provided cooling and dust removal mechanism, the hot and humid gas preliminarily cooled by the heat recovery mechanism will pass through the baffle and enter the cooling and dust removal mechanism. At this time, the PLC controller controls the operation of the cooling and dust removal mechanism and cools the preliminarily cooled hot and humid gas again. Under the low-temperature environment, water vapor condenses on the metal mesh plate with the dust carried in the hot and humid air as the crystal nucleus and gradually accumulates into water droplets, and finally drips to the bottom of the heat conduction area of the primary dust removal box through the metal mesh plate, completing the primary dust removal of the hot and humid gas. During the dust removal process, the heat dissipation sides of multiple semiconductor refrigeration 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 area at the top of the primary dust removal box, further improving the heat recovery effect during the fabric drying process and enhancing the utilization rate of heat, thereby reducing the energy consumption of fabric drying.

[0016] Through the provided secondary dust removal mechanism, when the hot and humid air carrying water liquid is transported to the ceramic filter cartridge of the purification box through the exhaust pipe, the hot and humid air will be dusted again by the ceramic filter cartridge at this time, and the gas and water liquid will pass through the ceramic filter cartridge and enter the purification box. Among them, the water liquid is replenished to the water liquid layer for reuse, and the dust-free and low-temperature air is discharged through the anti-static mechanism. This mechanism enables the breathable and moisture-permeable composite textile fabric drying exhaust dust removal device to not only have the function of recovering and reusing water, but also have the function of secondary dust removal, avoiding waste of water resources, improving the dust removal effect of the device, further enhancing the energy conservation and environmental protection performance of the fabric drying and processing, and improving the reliability of the device use.

[0017] Through the provided anti-static mechanism, when the gas discharged into the purification box is ejected through the nozzles of the anti-static mechanism, the water liquid in the water liquid layer will be sprayed onto the surrounding environment of the main body of the fabric drying equipment, avoiding the static electricity generated due to too low humidity around the main body of the fabric drying equipment. Moreover, through the humidity sensor and the micro waterproof electric push rod, the water liquid volume entering the anti-static mechanism can be adjusted. In a dry environment, the more water liquid is ejected with the gas, the better the anti-drying effect, that is, the better the anti-static effect. The water liquid volume entering through the water inlet pipe is inversely proportional to the ventilation diameter of the air inlet end of the arc-shaped pipe, reducing the probability of static electricity generation around the main body of the fabric drying equipment due to dryness. This mechanism enables the device to have the function of anti-static, and will not cause a large amount of dust to be adsorbed on the dried fabric, avoiding the situation of flaws on the fabric surface, improving the appearance quality and grade of the fabric, and at the same time reducing the probability of static electricity ignition, providing efficient protection for personnel safety and enterprise property.

The above-mentioned electrified devices and electrical connections are all prior arts, and the technology of the heat pipe 51 conducting heat is also a prior art, which will not be elaborated here.

[0028] Now, the operation principle of the present invention is described as follows: When the breathable and moisture-permeable composite textile fabric is dried by the fabric drying device, first pass the breathable and moisture-permeable composite textile fabric through the main body 2 of the fabric drying device, and set the corresponding drying temperature threshold on the control panel of the main body 2 of the fabric drying device according to the drying temperature requirement of the breathable and moisture-permeable composite textile fabric. Subsequently, start the main body 2 of the fabric drying device, and at the same time start the suction fan 81 through the PLC controller 4. The suction fan 81 sucks air through the air extraction pipe 82, the heat recovery area 54 of the primary dust removal box 1 and the activated carbon filter tank 59, and then conveys the sucked air into the main body 2 of the fabric drying device to be heated. 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 device needs to heat the air with high power and high energy consumption. After the air temperature reaches the standard, the air is ejected through the pipes and air nozzles inside the main body 2 of the fabric drying device, and the wet breathable and moisture-permeable composite textile fabric is dried by using the hot air flow. 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 device, and the air is filtered and purified during the process of passing through the activated carbon filter tank 59 to ensure the cleanliness of the air entering the main body 2 of the fabric drying device; When the humid and hot 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 elbow 56, the heat carried by the humid and hot gas is transferred to the bottom position of the heat pipe 51 through the metal mesh cover 52 at this time, and the primary cooling of the humid and hot gas is completed. Specifically, the liquid refrigerant at the bottom of the heat pipe 51 evaporates and absorbs heat, and the evaporated refrigerant will rise along the internal channel of the heat pipe 51 to the top position of the heat pipe 51. However, since the top of the heat pipe 51 is located in the heat recovery area 54, and the air sucked by the suction fan 81 will flow in the heat recovery area 54, then the flowing air will contact the top of the heat pipe 51. During this process, the flowing air will cool and liquefy the evaporated refrigerant at the top of the heat pipe 51 into a liquid state, and during the liquefaction process, the heat pipe 51 will dissipate the absorbed heat into the flowing air. These heats will return to the main body 2 of the fabric drying equipment through the intake mechanism 8 along with the flowing air. At this time, since the air entering the main body 2 of the fabric drying equipment carries its own heat, the temperature control component of the main body 2 of the fabric drying equipment will automatically adjust the heating power of the main body 2 of the fabric drying equipment. On the premise of meeting the air temperature rise requirement, the heating power is reduced, thereby reducing energy consumption. This mechanism enables the breathable and moisture-permeable composite textile fabric drying exhaust and dust removal device to have the function of recovering the heat in the humid and hot gas after fabric drying, improving the utilization rate of heat during the fabric drying process, greatly reducing the energy consumption cost of enterprises, and conforming to the current industry trend of energy conservation and emission reduction, improving the energy conservation and environmental protection performance of the breathable and moisture-permeable composite textile fabric drying and processing; The humid and hot gas preliminarily cooled by the heat recovery mechanism 5 will pass through the baffle 55 and enter the cooling and dust removal mechanism 6. At this time, the PLC controller 4 controls multiple semiconductor refrigeration chips 63 to work. The multiple semiconductor refrigeration chips 63 reduce the temperature of multiple metal mesh plates 62 through the heat conduction metal plate 61. And when the preliminarily cooled humid and hot gas passes through the multiple low-temperature metal mesh plates 62, it will be cooled again. The low-temperature environment causes the moisture in the humid and hot gas to liquefy into water droplets and drip to the bottom of the primary dust removal box 1. Under the low-temperature environment, the moisture condenses on the metal mesh plate 62 with the dust carried in the humid and hot air as the crystal nucleus and gradually accumulates into water droplets, and finally drips to the bottom of the heat conduction area 53 of the primary dust removal box 1 through the metal mesh plate 62, completing the primary dust removal of the humid and hot gas. During the dust removal process, the heat dissipation side of the multiple semiconductor refrigeration chips 63 will conduct the heat to the heat sink 64, and the heat sink 64 will further transfer the heat to the air flowing in the heat recovery area 54 at the top of the primary dust removal box 1, further improving the heat recovery effect during the fabric drying process and enhancing the utilization rate of heat, thereby reducing the energy consumption of fabric drying; When the humid and hot air carrying water liquid is transported to the ceramic filter cartridge 73 of the purification box 71 through the exhaust pipe 57, the humid and hot air will be dust-removed again by the ceramic filter cartridge 73 at this time, and the gas and water liquid will pass through the ceramic filter cartridge 73 and enter the purification box 71. Among them, the water liquid is supplemented to the water liquid layer 98 for reuse, and the dust-free and low-temperature air is discharged through the antistatic mechanism 9. During this process, the pressure sensor 75 detects 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 ceramic filter cartridge 73 reduces the effect of secondary dust removal due to dust clogging the filter channel, the air pressure inside the ceramic filter cartridge 73 will gradually increase and exceed the warning air pressure threshold preset by the PLC controller 4. Then, the PLC controller 4 controls the alarm 10 to alarm. The alarm 10 alarming reminds the staff that there is too much dust and impurities in the ceramic filter cartridge 73 in the purification box 71, which affects the dust removal effect, and the ceramic filter cartridge 73 needs to be cleaned and maintained in time. This mechanism enables the breathable and moisture-permeable composite textile fabric drying, exhaust, and dust removal device to not only have the function of water recovery and reuse but also have the function of secondary dust removal. It not only avoids wasting water resources but also improves the dust removal effect of the device, further enhances the energy conservation and environmental protection performance of fabric drying and processing, and improves the reliability of device use; When the gas discharged into the purification box 71 is ejected through the nozzle 93 of the anti-static mechanism 9, the water liquid in the water liquid layer 98 will be sprayed onto the surrounding environment of the fabric drying equipment main body 2, avoiding the static electricity situation caused by the too low humidity around the fabric drying equipment main body 2. Moreover, the humidity sensor 99 will detect the humidity of the surrounding environment of the fabric drying equipment main body 2 in real time, and convert the humidity value into an electric signal and transmit it to the PLC controller 4. If the humidity sensor 99 detects that the humidity value around the fabric drying equipment main body 2 is lower than the drying threshold preset by the PLC controller 4, the PLC controller 4 controls the mobile end of the micro waterproof electric push rod 96 to extend. The mobile end of the micro waterproof electric push rod 96 pushes the L-shaped shutter 95 to block the air inlet end at the bottom of the arc-shaped pipe 94. And the lower the humidity value detected by the humidity sensor 99, the greater the extension amount of the mobile end of the micro waterproof electric push rod 96. Until the mobile end of the micro waterproof electric push rod 96 is fully extended, at this time, the micro waterproof electric push rod 96 pushes the L-shaped shutter 95 to block three-quarters of the air inlet at the bottom end of the arc-shaped pipe 94. At this time, due to the reduction of the air inlet diameter of the arc-shaped pipe 94, the discharge speed and discharge volume of the gas in the purification box 71 through the arc-shaped pipe 94, the hard pipe 91, the arc-shaped hollow block 92 and the nozzle 93 are both reduced. Synchronously, the gas inside the purification box 71 increases, and the air pressure rises. The increased air pressure at the top of the purification box 71 will press down the water liquid in the water liquid layer 98 and discharge it into the arc-shaped pipe 94 through the water inlet pipe 97. The amount of water liquid entering through the water inlet pipe 97 is inversely proportional to the ventilation diameter of the air inlet end of the arc-shaped pipe 94, that is, the drier the surrounding of the fabric drying equipment main body 2 and the smaller the air inlet diameter of the arc-shaped pipe 94, the more water liquid is transported by the water inlet pipe 97 to the water liquid layer 98. At this time, more water liquid is carried by the gas entering the arc-shaped pipe 94 and finally sprayed onto the surrounding of the fabric drying equipment main body 2 through the arc-shaped hollow block 92 and the nozzle 93, improving the humidity of the surrounding environment, reducing the probability of static electricity generation due to dryness around the fabric drying equipment main body 2. This mechanism enables the device to have the function of anti-static, and will not cause a large amount of dust to be adsorbed on the dried fabric, avoiding the situation of defects on the fabric surface, improving the appearance quality and grade of the fabric, and at the same time reducing the probability of static electricity ignition, providing efficient protection for personnel safety and enterprise property.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
