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. 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.

[0010] Preferably, a sealing plate is inserted into the top of the No. 1 air tube. The sealing plate is used to open and close the No. 1 air tube. The sealing plate is sleeved with the telescopic rod and its bottom is fixedly connected to the No. 1 spring.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The processing unit can automatically switch purification modes according to the seasonal environment. During the rainy season, the waterproof and breathable membrane unfolds to filter moisture, preventing incomplete combustion and affecting the drying effect of clothes; during dry and dusty seasons, the HEPA filter activates to intercept dust and prevent clothes from becoming contaminated. The two purification modes are quickly switched through the linkage of magnetic blocks and electric push rods, and the sealed design ensures thorough purification, providing clean air for the drying process and ensuring the quality and safety of clothes from the source.

[0018] 2. The air conditioning and intake mechanisms work in tandem, dynamically matching the airflow and gas volume through motor speed adjustment. During the initial drying phase, as the fan speed increases, the gas volume increases simultaneously, ensuring an optimal combustion ratio between gas and air, rapid temperature rise, and prevention of odors. When cooling is required, the fan speed decreases, reducing the gas volume to maintain a low-temperature drying environment. This interconnected design ensures stable and controllable drying temperature, preventing over-drying or under-drying and guaranteeing consistent drying of garments.

[0019] 3. The internal drum assembly rotates at an appropriate speed, working in conjunction with the inner wall lifting plates to evenly tumble the garments, ensuring consistent heating of each garment and preventing localized over-drying or under-drying. The high-temperature resistant sealing strip on the airtight door ensures a sealed drying environment, reducing heat loss and improving drying efficiency. The entire drying process is highly automated, forming a closed loop from air purification to temperature control and garment tumbling, adapting to large-scale garment washing needs, ensuring product quality while improving production efficiency.

[0032] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 11 The present invention provides a technical solution: Example 1: Adapt to environmental conditions and ensure clean intake air.

[0034] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the processing mechanism 8 is the core of the intake air purification. Its No. 2 air pipe 81 is welded to the outside of the fan assembly 4, and its bottom is connected to the No. 3 air pipe 82, which is connected to the combustion zone inside the body 1. The No. 3 air pipe 82 has a central shaft 83 welded inside, and a bushing 84 is rotatably installed on the outside. The top of the bushing 84 is welded with a sealing plate 85, and the two sides are bonded with No. 3 magnetic blocks 86 with opposite magnetic properties. The bottom is welded with a U-shaped ring 87, and an electromagnetic plate 88 is embedded in the U-shaped ring 87. The bottom of the electromagnetic plate 88 is welded with a No. 3 plate 89, which is connected to the No. 3 air pipe 81. 2. The outer groove slides and is connected to the sealing plates 80 on both sides; the outer side of the No. 3 air pipe 82 is welded with the No. 4 plate 802, and an electric push rod 801 is fitted on it. Its output end is fixed to the No. 3 plate 89. The top of the No. 4 plate 802 is connected to the No. 1 spring strip 804, and the other end of the No. 1 spring strip 804 is connected to the waterproof and breathable membrane 803; the outer groove 809 of the machine body 1 is connected to the No. 2 spring strip 808, and the other end is connected to the HEPA filter 807. The waterproof and breathable membrane 803 and the HEPA filter 807 are connected to the sealing plate 85 through the No. 1 pull strip 805 and the No. 2 pull strip 806, respectively.

[0035] If it is the rainy season, moisture in the air intake needs to be removed: the electric push rod 801 is activated, pushing plate 89 to slide to the left along the outer groove of air pipe 82, causing electromagnetic plate 88 to move away from U-shaped ring 87; electromagnetic plate 88 generates a magnetic field when energized, attracting the opposite poles of magnetic block 86 on the left side of sealing plate 85, driving bushing 84 to rotate counterclockwise around central axis 83. When sealing plate 85 rotates, it pulls waterproof and breathable membrane 803 through pull strip 805 to unfold and extend into the right half of air pipe 82, while sealing plate 85 itself seals the left half of the cavity; outside air enters air pipe 81 through fan assembly 4, and when it flows through air pipe 82, waterproof and breathable membrane 803 filters water mist, preventing water mist from entering the combustion zone and causing incomplete combustion of gas, or adhering to the surface of clothes and affecting the drying effect.

[0036] When the sealing plate 85 and bushing 84 are in their original, vertical state, they divide the No. 3 air pipe 82 into two chambers, left and right. When the No. 3 magnetic block 86 on the left side of the sealing plate 85 is attracted by the electromagnetic plate 88, the sealing plate 85 rotates counterclockwise and seals the chamber of the No. 3 air pipe 82, ensuring that the introduced air must pass through the waterproof and breathable membrane 803 before entering the machine body 1. The waterproof and breathable membrane 803 passes through the No. 3 air pipe 82 and extends into it. The No. 3 air pipe 82 has a semi-circular groove at this location, and a flexible sealing ring is installed in the semi-circular groove. The flexible sealing ring is squeezed and compressed by the waterproof and breathable membrane 803 until it fits snugly against the waterproof and breathable membrane 803 without gaps.

[0037] In dry and dusty seasons, dust in the intake air needs to be intercepted: the electric push rod 801 drives the third plate 89 to slide to the right, the electromagnetic plate 88 and the third magnetic block 86 on the right side of the sealing plate 85 are attracted, and the bushing 84 rotates clockwise; the sealing plate 85 pulls the HEPA filter 807 through the second pull strip 806 to unfold it, extending into the left half of the third air pipe 82 and sealing the right half of the cavity; when the air flows through, the HEPA filter 807 intercepts dust particles, preventing dust from contacting clothes with the hot air and avoiding clothing contamination. The purified air is delivered to the combustion zone of the machine body 1 through the third air pipe 82 to provide clean air for gas combustion.

[0038] The HEPA filter 807 and the second elastic strip 806 work on the same principle as the waterproof and breathable membrane 803 and the first elastic strip 805. In addition, the first elastic strip 804 and the second elastic strip 808 respectively serve to reset the waterproof and breathable membrane 803 and the HEPA filter 807.

[0039] Example 2: Dynamic linkage matching to maintain a stable drying environment.

[0040] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the air conditioning mechanism 5 and the air intake mechanism 6 work together to achieve precise control of air volume and gas volume. The output end of the second motor 51 of the air conditioning mechanism 5 is connected to the fan inside the fan assembly 4. A support rod 9 is welded to the outside of the housing, and the bottom end of the support rod 9 is fixed to the first motor 7. A bearing 52 is sleeved on the outside of the output end of the second motor 51, and a circular sleeve 53 is connected to the outside of the bearing 52. An external threaded ring 54 is slidably fitted in the groove of the circular sleeve 53. The external threaded ring 54 is threadedly connected to an internal threaded sleeve 55. The internal threaded sleeve 55 is connected to a reset telescopic rod 56. The other end of the reset telescopic rod 56 is connected to a fitting ring assembly 57, and a spiral retaining ring 58 is connected to the outside of the fitting ring assembly 57. The external threaded ring 54 is threaded to an internal threaded sleeve 55. 4. Weld plate 59, with rail 50 connected to the outside of plate 59. Rail 50 is connected to magnetic block 501 and slides to fit plate 502. Plate 502 is connected to magnetic block 503 and spring rod 504 on both sides. The other end of spring rod 504 is connected to hemisphere 505. Air pipe 61 in air intake mechanism 6 is welded to the outside of body 1 and connects to combustion zone. Rail 62 is connected to the top. Telescopic rod 63 slides to fit inside rail 62. Spring 64 is connected to the outside of telescopic rod 63. Sealing plate 65 is inserted into the top of air pipe 61. Sealing plate 65 is sleeved with telescopic rod 63 and connected to spring 64.

[0041] In the initial stage of drying, rapid heating is required, which necessitates increasing the air volume and gas volume: Motor 51 starts, driving the fan in the fan assembly 4 to rotate, and simultaneously driving the inner threaded sleeve 55 at the output end to rotate; the inner threaded sleeve 55 and the outer threaded ring 54 are threadedly driven, pushing the outer threaded ring 54 to slide along the groove of the circular sleeve 53, driving the first plate 59 and the first rail 50 to move synchronously; the first magnetic block 501 and the second magnetic block 503 in the first rail 50 keep the second plate 502 in its initial position due to repulsive force, and the moving second plate 502 squeezes the sealing plate 65, pushing it to move upward along the first gas pipe 61, opening the gas passage, and natural gas enters the combustion zone through the first gas pipe 61. As the fan speed increases, the centrifugal force on the output shaft of motor 51 increases. The outer reset telescopic rod 56 of the inner threaded sleeve 55 expands outward under the action of centrifugal force, driving the fitting ring assembly 57 and the spiral retaining ring 58 to unfold synchronously. The expanding spiral retaining ring 58 squeezes the hemisphere 505, pushing the spring rod 504 and plate 502 to move along rail 50. It also overcomes the magnetic block repulsion force, increasing the squeezing force of plate 502 on the sealing plate 65, causing the sealing plate 65 to move further upward. The gas intake volume increases synchronously, ensuring that the gas-air ratio is maintained at the optimal combustion ratio, avoiding incomplete combustion of gas that produces odors, or insufficient heat that leads to slow drying.

[0042] When cooling is required and over-drying is to be avoided, the speed of motor 51 is reduced, the air volume is reduced, the centrifugal force is weakened, the resetting telescopic rod 56 retracts, the spiral retaining ring 58 is reset, and the squeezing force on the hemisphere 505 disappears; plate 502 is reset under the repulsive force of the magnetic block and the rebound action of spring 64, the sealing plate 65 moves down, the gas volume is reduced, and the low-temperature drying environment is maintained.

[0043] Example 3: Evenly tumble and dry to ensure garment quality.

[0044] like Figure 1 and Figure 2 As shown, the drum assembly 2 is rotatably mounted inside the machine body 1, and a sealing door 3 is connected to the outside via a hinged structure. The sealing door 3 has a built-in high-temperature resistant sealing strip, and a No. 1 motor 7 is bolted to the outside. The output end of the No. 1 motor 7 is connected to the drum assembly 2 via a belt. Purified air and natural gas are mixed and burned in the combustion zone of the machine body 1 to generate high-temperature hot air. The hot air fills the interior of the machine body 1 to form a sealed drying environment. The No. 1 motor 7 starts, driving the drum assembly 2 inside the machine body 1 to rotate clockwise at a speed of 8 r / min. The operator opens the sealing door 3, puts the clothes evenly into the drum assembly 2, where the inner wall of the drum is equipped with lifting plates to assist in turning the clothes. The sealing door 3 is then closed, and the clothes are turned and dried.

[0045] The working principle of this invention is as follows: Before drying, the air entering the machine body 1 needs to be purified to avoid dust or water mist affecting the drying quality. After the fan assembly 4 is started, 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 outer groove of the third air pipe 82, causing the electromagnetic plate 88 to move away from the U-shaped ring 87 and to the left. Then, the electromagnetic plate 88 is energized to generate a magnetic field, which is magnetically attracted to the third magnetic block 86 on the left side of the sealing plate 85, and synchronously drives the bushing 84 to rotate counterclockwise around the central axis 83. The sealing plate 85 is pulled by the first pull bar 805 to unfold the waterproof and breathable membrane 803 and extend it into the right half of the 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 water mist in the air, completing 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 magnetically attracts the third magnetic block 86 on the right side of the sealing plate 85, which eventually causes the sealing plate 85 to rotate clockwise. The second pull bar 806 then pulls the HEPA filter 807 to unfold and extend it into the left half of the cavity of the third air pipe 82. The HEPA filter 807 intercepts dust particles, completing air purification. The purified air is then delivered to the combustion zone inside the machine 1 through the third air pipe 82.

[0046] Dynamic airflow adjustment: Motor 51 drives the fan in the blower assembly 4 to rotate, simultaneously rotating the internal threaded sleeve 55 at the output end. The internal threaded sleeve 55 and the external threaded ring 54 are threadedly driven, pushing the external threaded ring 54 to slide along the groove on the surface of the circular sleeve 53. The external threaded ring 54 drives the first plate 59 and the first rail 50 to move synchronously. The first magnetic block 501 and the second magnetic block 503 in the first rail 50 keep the second plate 502 in its initial position due to repulsive force. The external threaded ring 54 extends outward from the internal threaded sleeve 55, causing the second plate 502 to squeeze the sealing plate 65 and push the sealing plate 65 upward. When the sealing plate 65 moves upward, the passage between the first gas pipe 61 and the combustion zone of the machine body 1 opens, and natural gas enters the combustion zone; when the sealing plate 65 moves downward, the passage closes, realizing the gas start-up and shut-off. Therefore, when Motor 51 drives the blower assembly 4 to introduce air into the combustion chamber of the machine body 1, the first gas pipe 61 connected to the natural gas will also open accordingly.

[0047] When the required air volume increases, the rotation speed of the output shaft of motor 51 increases to allow more outside air to enter the machine body 1. When the rotation speed of the output shaft of motor 51 increases, the reset telescopic rod 56, which is fixedly connected to the outside of the inner threaded sleeve 55, will expand outward synchronously with the fitting ring assembly 57 due to centrifugal force. At the same time, the spiral retaining ring 58, which is fixedly connected to the outside of the fitting ring assembly 57, will also expand outward synchronously and gradually squeeze the hemisphere 505. The squeezed hemisphere 505 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 causing the sealing plate 65 to move upward again, increasing the natural gas intake.

[0048] Purified air and natural gas mix and burn in the combustion zone of unit 1, generating high-temperature hot air that fills the interior of unit 1, creating a drying environment. Motor 7 starts, driving the drum assembly 2 inside unit 1 to rotate. Clothes to be dried are placed inside the drum assembly 2 through the sealed door 3. As the drum rotates, the clothes tumble and come into full contact with the high-temperature hot air, rapidly evaporating moisture and achieving uniform drying. The sealed door 3 ensures the airtightness of unit 1, reducing heat loss; the fan assembly 4 continuously delivers purified air, creating hot air circulation, further improving drying efficiency and uniformity. After drying, the gas and fan are turned off, and the sealed door 3 is opened to remove the dried clothes, completing one drying cycle.

Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
