Description

Technical Field

[0001] This invention relates to the field of natural gas drying technology, specifically to a commercial multi-path natural gas dryer. Background Technology

[0002] In households, hotels, and clothing dryers, clothes drying is a crucial process for ensuring the stability of stored clothes and improving the wearing experience. It is widely used for processing clothes made of various materials such as cotton, wool, silk, and synthetic fibers. Its core principle is to use high-temperature hot air to exchange heat with the surface of the clothes, causing the internal moisture to evaporate quickly. This keeps the moisture content within the required range for use, preventing clothes from becoming damp, moldy, developing odors, or wrinkling and deforming, while meeting the dryness requirements for daily wear or storage.

[0003] As people's demands for drying efficiency and garment protection quality increase, and given the differences in environmental conditions across regions and seasons (such as high humidity during the rainy season, high dust levels during the dry season, and severe dust pollution in industrial areas), the shortcomings of traditional drying equipment in areas such as "environmental adaptability, precise parameter control, and garment protection" are becoming increasingly apparent. For example, during the rainy season, the intake air can carry moisture, causing cotton clothes to remain damp after drying and wool clothes to shrink and deform; dust pollution can adhere to the surface of silk garments, affecting their cleanliness and appearance.

[0057] If it is in the rainy season, the water vapor in the intake air needs to be removed: the electric push rod 801 is started, the third plate 89 is slid along the groove outside the third gas pipe 82, the electromagnetic plate 88 is driven away from the U-shaped ring 87; the electromagnetic plate 88 generates a magnetic field when powered on, and the left three magnetic blocks 86 of the sealing plate 85 are attracted by the opposite poles, driving the shaft sleeve 84 to rotate counterclockwise around the center shaft 83. When the sealing plate 85 rotates, the waterproof breathable membrane 803 is pulled out by the first pull strip 805 and extends into the right half cavity of the third gas pipe 82, while the sealing plate 85 seals the left half cavity; the outside air enters the second gas pipe 81 through the fan assembly 4, and when flowing through the third gas pipe 82, the waterproof breathable membrane 803 filters the water mist, avoiding the water mist entering the combustion zone to cause the gas to burn insufficiently, or adhering to the surface of the clothes to affect the drying effect.

[0058] Wherein the sealing plate 85, shaft sleeve 84 in the original state, that is, the vertical state, will be three air pipe 82 into two chambers, when the sealing plate 85 left three magnetic block 86 by the electromagnetic plate 88 attraction, sealing plate 85 counterclockwise rotation and sealing plate 85 left three air pipe 82 chamber processing, so that the introduction of air must pass through waterproof breathable membrane 803 can continue to enter the body 1.

[0061] Example two, dynamic linkage matching, maintain stable drying environment.

[0062] As Figure 3 , Figure 4 , Figure 5 , Figure 6 And Figure 7As shown, the air adjusting mechanism 5 cooperates with the gas inlet mechanism 6 to realize accurate control of air volume and gas volume. The output end of the No. 2 motor 51 of the air adjusting mechanism 5 is connected with the fan in the fan assembly 4, a support rod 9 is welded outside the shell, and the bottom end of the support rod 9 is fixed with the No. 1 motor 7. The output end of the No. 2 motor 51 is sleeved with a bearing 52, the bearing 52 is connected with a circular sleeve 53 outside, the circular sleeve 53 is slidably matched with an external thread ring 54, the external thread ring 54 is threadedly connected with an internal thread sleeve 55, and the internal thread sleeve 55 is connected with a reset telescopic rod 56. The other end of the reset telescopic rod 56 is connected with a fitting ring assembly 57, and the outside of the fitting ring assembly 57 is connected with a spiral check ring 58. The external thread ring 54 is welded with a No. 1 plate 59, the outside of the No. 1 plate 59 is connected with a No. 1 rail 50, the No. 1 rail 50 is connected with a No. 1 magnetic block 501 inside, and is slidably matched with a No. 2 plate 502. The two sides of the No. 2 plate 502 are respectively connected with a No. 2 magnetic block 503 and a spring rod 504, and the other end of the spring rod 504 is connected with a hemisphere 505. A No. 1 gas pipe 61 in the gas inlet mechanism 6 is welded outside the machine body 1 and is connected with the combustion area, the top is connected with a No. 2 rail 62, the inside of the No. 2 rail 62 is slidably matched with a telescopic rod 63, the outside of the telescopic rod 63 is connected with a No. 1 spring 64, the top of the No. 1 gas pipe 61 is inserted with a sealing plate 65, the sealing plate 65 is sleeved with the telescopic rod 63 and is connected with the No. 1 spring 64.

[0063] In the initial stage of drying, the air volume and the gas volume need to be increased: the No. 2 motor 51 is started to drive the fan in the fan assembly 4 to rotate, and at the same time drive the internal thread sleeve 55 in the output end to rotate; the internal thread sleeve 55 is threadedly connected with the external thread ring 54 to drive the external thread ring 54 to slide along the groove of the circular sleeve 53, drive the No. 1 plate 59 and the No. 1 rail 50 to move synchronously; the No. 1 magnetic block 501 and the No. 2 magnetic block 503 in the No. 1 rail 50 keep the No. 2 plate 502 in the initial position due to the repulsive force, and the moving No. 2 plate 502 extrudes the sealing plate 65 to drive it to move upward along the No. 1 gas pipe 61, open the gas passage, and natural gas is introduced into the combustion area through the No. 1 gas pipe 61.

[0064] With the increase of the fan speed, the centrifugal force of the output shaft of the No. 2 motor 51 increases, the reset telescopic rod 56 outside the internal thread sleeve 55 is expanded outward under the action of the centrifugal force, and the fitting ring assembly 57 and the spiral check ring 58 are expanded synchronously; the expanded spiral check ring 58 extrudes the hemisphere 505, drives the spring rod 504 and the No. 2 plate 502 to move along the No. 1 rail 50, and overcomes the repulsive force of the magnetic block, increases the extrusion force of the No. 2 plate 502 on the sealing plate 65, and makes the sealing plate 65 move further upward, so that the gas inlet volume is increased synchronously, the ratio of gas and air is maintained at the best combustion ratio, and the incomplete combustion of gas is avoided to avoid the generation of peculiar smell or the slow drying caused by insufficient heat.

[0065] When the temperature needs to be reduced and excessive drying is avoided, the speed of the second motor 51 is reduced, the air volume is reduced, the centrifugal force is weakened, the reset telescopic rod 56 is retracted, the spiral check ring 58 is reset, the extrusion force on the hemispherical body 505 disappears, the second plate 502 is reset under the repulsion of the magnetic block and the rebound of the first spring 64, the sealing plate 65 moves down, the gas volume is reduced, and the low-temperature drying environment is maintained.

[0066] Example three, uniform turning and drying, guaranteeing clothes quality.

[0067] As shown in Figure 1 and Figure 2 , the drum assembly 2 is rotatably installed inside the body 1, and the sealing door 3 is connected to the outside through a hinged structure. The sealing door 3 is provided with a high-temperature-resistant sealing rubber strip inside, and the outside is bolted with a first motor 7. The output end of the first motor 7 is connected with the drum assembly 2 through a belt. The purified air is mixed with natural gas in the combustion area of the body 1 to produce high-temperature hot air, and the hot air fills the inside of the body 1 to form a sealed drying environment. The first motor 7 is started to drive the drum assembly 2 in the body 1 to rotate clockwise at a speed of 8r / min. The operator opens the sealing door 3 and evenly puts the clothes into the drum assembly 2. The inner wall of the drum is provided with a scraper to assist the clothes to turn over. The sealing door 3 is closed, and the clothes are turned over and dried.

[0068] The working principle of the present application is that the air entering the body 1 needs to be purified before drying to avoid dust or water mist affecting the drying quality. After the fan assembly 4 is started, the outside air is transported to the third air pipe 82 through the second air pipe 81. If the outside environment is high temperature and high humidity, the electric push rod 801 pushes the third plate 89 to slide along the outside slot of the third air pipe 82, drives the electromagnetic plate 88 to move away from the U-shaped ring 87 and to the left. Then the electromagnetic plate 88 generates a magnetic field after being electrified, and is magnetically attracted to the three magnetic blocks 86 on the left side of the sealing plate 85, and synchronously drives the shaft sleeve 84 to rotate counterclockwise around the center shaft 83. The sealing plate 85 expands the waterproof and breathable membrane 803 by pulling it through the first pull strip 805, and extends into the right half cavity of the third air pipe 82. The left side is sealed by the counterclockwise deflected sealing plate 85. The waterproof and breathable membrane 803 filters the water mist in the air to complete air purification. Similarly, when the outside environment is dusty, the electric push rod 801 drives the electromagnetic plate 88 to move to the right. Then the electromagnetic plate 88 will magnetically attract the three magnetic blocks 86 on the right side of the sealing plate 85, finally making the sealing plate 85 rotate clockwise, and expanding the HEPA filter screen 807 by pulling it through the second pull strip 806, and extending into the left half cavity of the third air pipe 82. The HEPA filter screen 807 intercepts dust particles to complete air purification. The purified air is transported to the combustion area inside the body 1 through the third air pipe 82.

[0069] Air volume dynamic adjustment: the second motor 51 drives the fan in the fan assembly 4 to rotate, and at the same time drives the inner threaded sleeve 55 at the output end to rotate. The inner threaded sleeve 55 is in threaded transmission with the outer threaded ring 54, pushes the outer threaded ring 54 to slide along the groove on the surface of the circular sleeve 53, and drives the first plate 59 and the first rail 50 to move synchronously. The repulsion between the first magnetic block 501 and the second magnetic block 503 in the first rail 50 keeps the second plate 502 at the initial position, and the outward extension of the outer threaded ring 54 from the inner threaded sleeve 55 makes the second plate 502 press the blocking plate 65 and push the blocking plate 65 to move upwards. When the blocking plate 65 moves upwards, the first gas pipe 61 and the passage in the combustion area of the machine body 1 are opened, and natural gas is introduced into the combustion area; when the blocking plate 65 moves downwards, the passage is closed, realizing the opening and closing of the gas. Therefore, when the second motor 51 drives the fan assembly 4 to introduce air into the combustion chamber of the machine body 1, the first gas pipe 61 connected with the natural gas will also be opened accordingly.

[0070] When the base of the required air becomes larger, the speed of the output shaft of the second motor 51 is increased, so that more air from the outside enters the machine body 1. When the speed of the output shaft of the second motor 51 increases, the reset telescopic rod 56 fixedly connected to the outer side of the inner threaded sleeve 55 will expand outward synchronously due to centrifugal force, and the spiral check ring 58 fixedly connected to the outer side of the embedded ring assembly 57 will also expand outward synchronously, gradually pressing the hemispheres 505, and the hemispheres 505 subjected to the pressing will push the spring rod 504 and move the second plate 502 along the first rail 50 to the other end, thereby increasing the moving distance of the second plate 502 and making the blocking plate 65 move upwards again and increasing the air intake of the natural gas.

[0071] The purified air and natural gas are mixed and burned in the combustion area of the machine body 1 to produce high-temperature hot air, and the hot air fills the inside of the machine body 1 to form a drying environment. The first motor 7 is started to drive the roller assembly 2 in the machine body 1 to rotate, the clothes to be dried are put into the roller assembly 2 through the sealing door 3, the clothes are continuously turned over with the rotation of the roller, fully contact with the high-temperature hot air, and quickly evaporate the moisture to realize uniform drying. The sealing door 3 ensures the sealing of the machine body 1 and reduces heat loss; the fan assembly 4 continuously delivers purified air to form a hot air circulation, further improving the drying efficiency and uniformity. After drying is completed, the gas and the fan are turned off, and the sealing door 3 is opened to take out the dry clothes, completing a drying process.

[0072] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Those skilled in the art can make various modifications without creative labor, which are all within the scope of protection of the present application.
