Description

Technical Field

[0001] This application belongs to the technical field of composite air ducts, and particularly relates to a composite air duct with good filtering effect. Background Art

[0002] The composite air duct, represented by the rubber-plastic composite air duct, is a rubber-plastic composite air duct system made of rubber composite thermal insulation materials, which can completely replace traditional air ducts, dampers, air outlets, static pressure boxes, and thermal insulation materials in the air supply system of air conditioners.

[0003] The existing Chinese patent with the publication number CN116558009B discloses a composite air duct that is easy to install, including a ventilation pipe, an exhaust pipe, an air delivery pipe, etc.; the upper part of the ventilation pipe is connected to the exhaust pipe; the lower part of the ventilation pipe is connected to the air delivery pipe, and bolts can make the exhaust pipe and the air delivery pipe more convenient to install on the ventilation pipe and filter the discharged gas.

[0004] The above-mentioned composite air duct can filter the discharged gas and remove oil stains and impurity particles to protect the environment. However, the composite air duct removes the oil stains on its internal components through a scraper. After the scraper is contaminated with a large amount of oil stains, its ability to remove oil stains will become weak, and the inside of the composite air duct will be blocked, which is not convenient for use. Utility Model Content

[0005] The purpose of this application is to provide a composite air duct with good filtering effect for the above-mentioned existing technical problems. It is convenient to filter oil stains and impurity particles in the air, and can automatically maintain the filtering device to ensure that the filtering device can work effectively for a long time. At the same time, the inside of the composite air duct is not easily blocked, and the practicability is relatively high.

[0006] This application provides a composite air duct with good filtering effect, including an air duct body, and the air duct body includes:

[0007] A filtering device, including a filter plate, a scraper, a temperature adjustment mechanism, and a cleaning mechanism;

[0008] A waste treatment device, including a waste collection box;

[0009] A groove, which cooperates with the filter plate;

[0010] A fastening plate, which is in threaded cooperation with the filter plate;

[0011] Among them, the filter plate and the scraper cooperate with each other.

[0012] In this technical solution, by arranging a filtering device and a waste treatment device in the air duct body, and installing this composite air duct in facilities such as factory areas, when the external air with oil stains and impurities enters the inside of the air duct body, the temperature of the filter plate is reduced through the temperature adjustment mechanism to facilitate the adsorption of oil stains by the filter plate. At the same time, the filter plate can effectively filter out impurities from the air, enabling the air duct body to have excellent filtering effect. Then, the scraper is controlled to slide on the filter plate, and the cleaning mechanism is started simultaneously. The cleaning mechanism is used to wash the scraper and the filter plate to keep the scraper and the filter plate clean. The scraper and the cleaning mechanism cooperate to wash the oil stains and impurities into the waste collection box in the waste treatment device. The cooperation between the groove and the filter plate facilitates the user to assemble the filter plate on the air duct body. The fastening plate and the filter plate are in threaded cooperation, enabling the filter plate to be stably installed on the air duct body for convenient use.

[0013] Further, the filtering device includes:

[0014] A sealing ring placed on the filter plate;

[0015] A motor, including a lead screw;

[0016] Wherein, the sealing ring cooperates with the fastening plate, and the lead screw cooperates with the scraper.

[0017] In this technical solution, by arranging a sealing ring on the filter plate and the cooperation between the sealing ring and the fastening plate, the sealing performance inside the air duct body is improved, which can effectively enhance the filtering effect of the filtering device. The scraper cooperates with the motor on the lead screw to control the rotation of the motor to drive the rotation of the lead screw, and the lead screw then drives the scraper to slide on the filter plate, facilitating the removal of oil stains and impurities on the filter plate by the scraper.

[0018] Further, the temperature adjustment mechanism includes:

[0019] An oil removal block;

[0020] A semiconductor refrigerator placed inside the oil removal block;

[0021] A hair dryer, including a first heating wire;

[0022] A sliding baffle, including an electromagnet and a return spring;

[0023] A permanent magnet placed at the air duct body;

[0024] Wherein, the air duct body is provided with an installation groove, the oil removal block is provided with a liquid collection groove, the hair dryer is placed in the installation groove, and the electromagnet is connected to the permanent magnet after being energized.

[0025] In this technical solution, an oil removal block and a semiconductor cooler are arranged in the temperature adjustment mechanism. The semiconductor cooler is placed inside the oil removal block. When the staff sucks the external air into the factory area, the semiconductor cooler is controlled to work simultaneously. The semiconductor cooler is used to lower the temperature of the oil removal block, so that the oil removal block can effectively adsorb the oil stains in the external air, and there is no need to remove the oil stains through the filter plate. A liquid collection tank is also arranged on the oil removal block, and the outlet of the liquid collection tank faces the waste collection box. When it is necessary to process the oil stains on the oil removal block, the electromagnet is controlled to be energized. After the electromagnet is energized, it is connected to the permanent magnet and drives the sliding baffle to displace on the installation groove. At this time, the air outlet of the blower in the installation groove is not blocked by the sliding baffle. At the same time, the blower and the first heating wire are controlled to work together. After the air blown by the blower is heated by the first heating wire, it can effectively increase the temperature inside the air duct body and reduce the adsorption capacity of the oil stains on the oil removal block. The outlet of the cleaning mechanism is aligned with the oil removal block, which is convenient for the cleaning liquid mixed with oil stains to be discharged into the waste collection box along the liquid collection tank, ensuring that the oil removal block can continuously clean the oil stains and facilitating recycling.

[0026] Further, the cleaning mechanism includes:

[0027] A cleaning liquid tank, including a first spray head;

[0028] A clean water tank, including a second spray head;

[0029] Among them, the clean water tank is provided with a second heating wire, and the liquid outlets of the first spray head and the second spray head face the scraper and the oil removal block.

[0030] In this technical solution, by arranging a cleaning liquid tank with a first spray head and a clean water tank with a second spray head at the cleaning mechanism, a second heating wire is arranged inside the clean water tank. The first spray head can spray the cleaning liquid onto the scraper and the oil removal block, and the second spray head can spray the relatively hot clean water onto the scraper and the oil removal block. After the cleaning liquid and the relatively hot clean water are mixed, the cleaning function can be greatly improved, which is convenient for cleaning the oil stains on the oil removal block and the impurities on the scraper and the filter plate.

[0031] Further, the waste treatment device includes:

[0032] A sewage pipe, which is connected to the waste collection box;

[0033] A box cover, including a rack;

[0034] Among them, the lead screw is provided with a gear, and the gear is engaged with the rack.

[0035] In this technical solution, a sewage pipe is provided in the waste treatment device, a rack is provided at the box cover, a gear is provided at the lead screw, and the gear and the rack cooperate with each other. When the motor rotates, while driving the scraper to reciprocate, it drives the rack to slide back and forth on the gear, that is, the box cover slides back and forth at the waste collection box. When the scraper scrapes the waste to the vicinity of the waste collection box, the box cover slides to open the opening of the waste collection box, which is convenient for the waste collection box to collect the waste on the filter plate and the oil removal block. At the same time, it is convenient for the inside of the waste collection box to be flushed through the first spray head and the second spray head. The second spray head sprays warm water, which can effectively drive the flow of oil stains and impurities after mixing with the cleaning liquid sprayed by the first spray head, facilitating the discharge of oil stains and impurities along the sewage pipe, and reducing the probability of blockage inside the sewage pipe, enhancing the practicability. After the scraper resets, the box cover resets simultaneously to close the opening of the waste collection box, reducing the probability of the sewage pipe being blocked by waste.

[0036] Further, the air duct body is provided with a metal layer and a flame retardant layer.

[0037] In this technical solution, by successively covering the metal layer and the flame retardant layer on the air duct body, with the flame retardant layer placed on the outermost side of the air duct body, it can prevent the air duct body from catching fire due to external factors such as high temperature, increasing safety. The metal layer is placed inside the air duct body, which can effectively improve the stiffness and strength of the air duct body, thereby extending the service life of the air duct body. Moreover, the metal layer can reduce the probability of oil stains and impurities adhering to the inner side wall of the air duct body, thus avoiding blockage inside the air duct body and increasing practicability.

[0038] The beneficial effects of this application are:

[0039] 1. The filter plate can effectively filter out impurities and oil stains from the external air. After more impurities adhere to the filter plate, control the scraper to slide on the filter plate, and at the same time start the cleaning mechanism. The scraper and the cleaning mechanism are used in combination to wash the oil stains and impurities into the waste collection box in the waste treatment device, facilitating the continuous filtration and cleaning of oil stains and impurities by the air duct body.

[0040] 2. The outlet of the liquid collecting tank on the oil removal block faces the waste collection box. When oil stains need to be treated, control the electromagnet to be energized. The electromagnet drives the sliding baffle to displace, so that the air outlet of the hair dryer is not blocked. At the same time, control the hair dryer and the first heating wire to work together. The air blown out by the hair dryer can effectively increase the temperature inside the air duct body after heating, reducing the adsorption ability of oil stains on the oil removal block, facilitating the cleaning mechanism to wash the oil stains on the oil removal block, and making the cleaning liquid mixed with the oil stains drain into the waste collection box along the liquid collecting tank, facilitating continuous cleaning.

[0041] 3. When the scraper scrapes the waste to the vicinity of the waste collection box, the box cover slides through the linkage relationship, so that the opening of the waste collection box is opened, facilitating the waste collection box to collect waste and facilitating the internal cleaning of the waste collection box through the cleaning mechanism. The oil stains and impurities are discharged along the sewage pipe, and the relatively high-temperature mixed cleaning liquid reduces the probability of blockage inside the sewage pipe, enhancing the practicability.

[0050] The following will combine the accompanying drawings to provide a detailed description of the embodiments of this application through specific embodiments and their application scenarios.

[0051] Embodiment 1:

[0052] As Figures 1-5 shown, the embodiment of this application provides a composite air duct with good filtering effect, including an air duct body 100, and the air duct body 100 includes:

[0053] A filtering device 200, including a filter plate 210, a scraper 220, a temperature adjustment mechanism 230 and a cleaning mechanism 240;

[0054] A waste treatment device 300, including a waste collection box 310;

[0055] A groove 110, which cooperates with the filter plate 210;

[0056] A fastening plate 120, which is in threaded cooperation with the filter plate 210;

[0057] Among them, the filter plate 210 cooperates with the scraper 220.

[0058] By setting a filtering device 200 and a waste treatment device 300 in the air duct body 100 and installing this composite air duct in facilities such as factory areas, when the external air with oil stains and impurities enters the interior of the air duct body 100, the temperature of the filter plate 210 is reduced through the temperature adjustment mechanism 230 to facilitate the adsorption of oil stains by the filter plate 210. At the same time, the filter plate 210 can effectively filter out impurities from the air, enabling the air duct body 100 to have excellent filtering effects. Then, the scraper 220 is controlled to slide on the filter plate 210, and the cleaning mechanism 240 is started simultaneously. The cleaning mechanism 240 is used to wash the scraper 220 and the filter plate 210 to keep the scraper 220 and the filter plate 210 clean. The cooperation of the scraper 220 and the cleaning mechanism 240 can wash the oil stains and impurities into the waste collection box 310 in the waste treatment device 300. The cooperation between the groove 110 and the filter plate 210 facilitates the user to assemble the filter plate 210 on the air duct body 100. The fastening plate 120 and the filter plate 210 are in threaded cooperation, enabling the filter plate 210 to be stably installed on the air duct body 100 for convenient use.

[0059] Further, the filtering device 200 includes:

[0060] A sealing ring 250, which is placed on the filter plate 210;

[0061] A motor 260, including a lead screw 261;

[0062] Among them, the sealing ring 250 cooperates with the fastening plate 120, and the lead screw 261 cooperates with the scraper 220.

[0063] By setting a sealing ring 250 on the filter plate 210 and the cooperation between the sealing ring 250 and the fastening plate 120, the sealing performance inside the air duct body 100 is improved, and the filtering effect of the filtering device 200 can be effectively enhanced. The scraper 220 cooperates with the motor 260 on the lead screw 261. By controlling the rotation of the motor 260, the lead screw 261 is driven to rotate, and the lead screw 261 then drives the scraper 220 to slide on the filter plate 210, facilitating the removal of oil stains and impurities on the filter plate 210 by the scraper 220.

[0064] Further, the temperature adjustment mechanism 230 includes:

[0065] An oil removal block 231;

[0066] A semiconductor refrigerator 232, which is placed inside the oil removal block 231;

[0067] A hair dryer 233, including a first heating wire 236;

[0068] A sliding baffle 234, including an electromagnet 237 and a return spring 238;

[0069] A permanent magnet 235, which is placed at the air duct body 100;

[0070] Wherein, the air duct body 100 is provided with an installation groove 130, the oil removal block 231 is provided with a liquid collecting groove 239, the hair dryer 233 is placed in the installation groove 130, and a connection is established between the electromagnet 237 and the permanent magnet 235 after the electromagnet 237 is energized.

[0071] By arranging the oil removal block 231 and the semiconductor cooler in the temperature regulating mechanism 230, with the semiconductor cooler placed inside the oil removal block 231, when the staff sucks external air into the factory area, the semiconductor cooler 232 is controlled to work simultaneously. The semiconductor cooler 232 is used to lower the temperature of the oil removal block 231, enabling the oil removal block 231 to effectively adsorb the oil stains in the external air, eliminating the need to remove the oil stains through the filter plate 210. The oil removal block 231 is also provided with a liquid collecting groove 239, and the outlet of the liquid collecting groove 239 faces the waste collection box 310. When it is necessary to clean the oil stains on the oil removal block 231, the electromagnet 237 is controlled to be energized. After the electromagnet 237 is energized, a connection is established between it and the permanent magnet 235, driving the sliding baffle 234 to displace on the installation groove 130. At this time, the air outlet of the hair dryer 233 in the installation groove 130 is not blocked by the sliding baffle 234. Meanwhile, the hair dryer 233 and the first heating wire 236 are controlled to work together. The air blown out by the hair dryer 233 is heated by the first heating wire 236, which can effectively increase the temperature inside the air duct body 100 and reduce the adsorption capacity of the oil stains on the oil removal block 231. The outlet of the cleaning mechanism 240 is aligned with the oil removal block 231, facilitating the cleaning liquid mixed with oil stains to be discharged along the liquid collecting groove 239 into the waste collection box 310, ensuring that the oil removal block 231 can continuously clean the oil stains and facilitating recycling.

[0072] Further, the cleaning mechanism 240 includes:

[0073] A cleaning liquid tank 241, including a first spray head 243;

[0074] A clean water tank 242, including a second spray head 244;

[0075] Wherein, the clean water tank 242 is provided with a second heating wire 245, and the liquid outlets of the first spray head 243 and the second spray head 244 face the scraper 220 and the oil removal block 231 respectively.

[0076] By arranging a cleaning liquid tank 241 with a first spray head 243 and a clear water tank 242 with a second spray head 244 at the cleaning mechanism 240, a second electric heating wire 245 is arranged inside the clear water tank 242. The first spray head 243 can spray the cleaning liquid onto the scraper 220 and the oil removal block 231, and the second spray head 244 can spray hot clear water onto the scraper 220 and the oil removal block 231. After the cleaning liquid and the hot clear water are mixed, the cleaning function can be greatly improved, which is convenient for cleaning the oil stains on the oil removal block 231 and the impurities on the scraper 220 and the filter plate 210.

[0077] Embodiment 2:

[0079] A sewage discharge pipe 320, which is connected between the waste collection box 310;

[0080] A box cover 330, including a rack 331;

[0081] Wherein, a gear 262 is arranged on the lead screw 261, and the gear 262 is engaged with the rack 331.

[0082] By arranging a sewage discharge pipe 320 in the waste treatment device 300, a rack 331 is arranged at the box cover 330, a gear 262 is arranged at the lead screw 261, and the gear 262 is engaged with the rack 331. When the motor 260 rotates, while driving the scraper 220 to reciprocate, it drives the rack 331 to reciprocate and slide at the gear 262, that is, the box cover 330 reciprocates and slides at the waste collection box 310. When the scraper 220 scrapes the waste to the vicinity of the waste collection box 310, the box cover 330 slides, so that the opening of the waste collection box 310 is opened, which is convenient for the waste collection box 310 to collect the waste on the filter plate 210 and the oil removal block 231. At the same time, it is convenient for the inside of the waste collection box 310 to be flushed through the first spray head 243 and the second spray head 244. The second spray head 244 sprays hot clear water, and after being mixed with the cleaning liquid sprayed by the first spray head 243, it can effectively drive the flow of oil stains and impurities, which is convenient for the oil stains and impurities to be discharged along the sewage discharge pipe 320, and reduces the probability of blockage inside the sewage discharge pipe 320, enhancing the practicability. After the scraper 220 resets, the box cover 330 resets at the same time to close the opening of the waste collection box 310, so as to reduce the probability of the sewage discharge pipe 320 being blocked by waste.

[0083] Furthermore, a metal layer 140 and a flame retardant layer 150 are arranged on the air duct body 100.

[0084] By successively covering the air duct body 100 with a metal layer 140 and a flame retardant layer 150, with the flame retardant layer 150 placed on the outermost side of the air duct body 100, it is possible to prevent the air duct body 100 from catching fire due to external factors such as high temperature, increasing safety. The metal layer 140 is placed inside the air duct body 100, which can effectively improve the stiffness and strength of the air duct body 100, thereby extending the service life of the air duct body 100. Moreover, the metal layer 140 can reduce the probability of oil stains and impurities adhering to the inner side wall of the air duct body 100, thus preventing blockage inside the air duct body 100 and increasing practicality.
