Description

Technical Field

[0001] This utility model belongs to the field of dehumidifier technology, specifically relating to a single-fan rotary dehumidifier. Background Technology

[0002] There are many types of dehumidifiers on the market, including refrigeration dehumidifiers, rotary dehumidifiers, solution dehumidifiers, and duct dehumidifiers. Among them, rotary dehumidifiers are devices that remove moisture from the air through the principle of physical adsorption. Their working principle is based on physical adsorption: when humid air passes through the treatment zone, water vapor is adsorbed by the moisture-absorbing material in the rotor, and the dried air is then expelled. Subsequently, the rotor rotates to the regeneration zone, where heated air decomposes and absorbs the adsorbed water, expelling it outdoors, thus restoring the rotor's moisture-absorbing capacity. This process is continuously repeated, ensuring the dehumidifier operates consistently and stably. Due to their high efficiency and stable performance, rotary dehumidifiers are widely used in places requiring precise humidity control, such as underground buildings, pharmaceutical plants, food processing plants, and operating rooms.

[0003] However, the current rotary dehumidifier has a complex structure and a relatively large number of components, which leads to higher raw material and labor costs during the production process, thus easily reducing the production profit of rotary dehumidifiers.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a single-fan rotary dehumidifier.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0038] like Figures 1 to 7 As shown, a single-fan rotary dehumidifier according to one embodiment of the present invention includes a housing 1, a second mounting bracket 2, a dehumidification mechanism 3, and a regeneration heater 4.

[0039] The housing 1 is a sealed structure made of stainless steel to meet corrosion resistance requirements.

[0040] In addition, a partition 101 is provided inside the housing 1, and a first cavity 102 and a second cavity 103 are formed between the partition 101 and the inner wall of the housing 1. The first cavity 102 is used to install the processing fan 201 and the dehumidifying impeller 302, and the second cavity 103 is used for the discharge of dry air and the installation of the regeneration heater 4.

[0041] Specifically, the partition 101 is provided with a dry air passage 1011 and a regeneration air passage 1012. The first cavity 102 is connected to the second cavity 103 through the dry air passage 1011. The air dehumidified by the dehumidifying wheel 302 is discharged from the housing 1 through the dry air passage 1011 and the dry air duct 107. The hot air generated by the regeneration heater 4 can carry away the humid air on the dehumidifying wheel 302 through the regeneration air passage 1012. Some of the gas in the first cavity 102 is then discharged from the housing 1 through the regeneration air outlet 303 and the regeneration air duct 106.

[0042] In addition, a first mounting bracket 1013 is installed on the partition 101. The first mounting bracket 1013 is located outside the regeneration air vent 1012, and the regeneration heater 4 is installed on the first mounting bracket 1013. The first mounting bracket 1013 is used to install the regeneration heater 4 so that the regeneration heater 4 can be used to heat the air, so that the moisture in the dehumidification wheel 302 can be released, thereby restoring the moisture absorption capacity of the dehumidification wheel 302.

[0043] like Figures 1 to 7 As shown, one side wall of the housing 1 is provided with an air inlet 104 and a regeneration air duct 106. The first cavity 102 is connected to the outside through the air inlet 104 and the regeneration air duct 106. Air enters the first cavity 102 through the air inlet 104 and is dehumidified by the dehumidification mechanism 3. The humid air on the dehumidification wheel 302 can be discharged through the regeneration air duct 106 to achieve dry and wet air separation.

[0044] The housing 1 is equipped with a filter screen 105, which covers the air inlet 104, making it difficult for dust from the outside air to enter the housing 1.

[0045] In addition, a dry air duct 107 is provided on another side wall of the housing 1, and the second cavity 103 is connected to the outside through the dry air duct 107. The dehumidified air is discharged through the dry air duct 107 to achieve dry and wet air separation.

[0046] Specifically, a handle 108 is installed on the housing 1 to facilitate moving the housing 1.

[0047] In addition, sealing rings are provided at the ports of air inlet 104, regeneration air duct 106 and dry air duct 107 to seal the ports and to reduce vibration.

[0048] like Figures 1 to 7 As shown, the second mounting bracket 2 is installed inside the first cavity 102, and a processing fan 201 is mounted on the second mounting bracket 2, corresponding to the air inlet 104. The processing fan 201 is used to purify the air and guide the airflow direction, delivering the treated dry air to the space that needs dehumidification.

[0049] like Figures 1 to 7 As shown, the dehumidification mechanism 3 is installed on the partition 101 and is used to dehumidify the air entering the housing 1.

[0050] The dehumidification mechanism 3 includes a third mounting bracket 301, which is connected to the partition 101 and the bottom wall of the first cavity 102. The third mounting bracket 301 is used to install the dehumidification rotor 302 and the regeneration air outlet 303.

[0051] In addition, a dehumidifying wheel 302 is rotatably connected between the third mounting bracket 301 and the partition 101. The dehumidifying wheel 302 adopts a honeycomb structure, which features a large moisture absorption area and strong moisture absorption capacity. The installation position of the dehumidifying wheel 302 is as follows: Figure 2 As shown, it is located in the middle of the first cavity 102 and the second cavity 103.

[0052] Specifically, a regeneration air outlet 303 is connected to the third mounting bracket 301. The regeneration air outlet 303 corresponds to the regeneration air hole 1012 and the regeneration air duct 106. The humid air on the dehumidifying wheel 302 is discharged through the regeneration air outlet 303 under the action of the regeneration heater 4, and is discharged from the housing 1 through the regeneration air duct 106.

[0053] like Figures 1 to 7 As shown, a motor 304 is installed on the partition 101, and a transmission mechanism is connected between the output end of the motor 304 and the dehumidifying wheel 302. The motor 304 drives the dehumidifying wheel 302 to rotate through the transmission mechanism, which can not only dehumidify the air, but also discharge the humid air adsorbed on the dehumidifying wheel 302, so as to achieve dry and wet air separation.

[0054] The motor 304 has a pulley connected to its output end, and the transmission mechanism includes a belt 305 connected to the pulley and the outside of the dehumidifying wheel 302. When the motor 304 is running, it drives the dehumidifying wheel 302 to rotate via the pulley and belt 305, thereby drying the air. Simultaneously, the humid air on the dehumidifying wheel 302 is discharged through the regeneration air outlet 303 under the action of the regeneration heater 4.

[0055] In addition, several meshing belts 306 are connected to the outer wall of the dehumidifying wheel 302. The meshing belts 306 mesh with the belt 305, and the belt 305 can drive the dehumidifying wheel 302 to rotate through the meshing belts 306.

[0056] like Figures 1 to 7 As shown, an L-shaped bracket 307 is connected to the partition 101, and the L-shaped bracket 307 is used to install the tensioning frame 308. A rotating shaft is connected between the motor 304 and the L-shaped bracket 307, and the tensioning frame 308 is rotatably connected to the rotating shaft. The tensioning frame 308 is used to install the tensioning pulley 309 in order to tension the belt 305 and ensure that the belt 305 can stably drive the dehumidifying wheel 302 to rotate.

[0057] Among them, a tensioning wheel 309 is rotatably connected to the tensioning frame 308, and the belt 305 passes around the tensioning wheel 309. The tensioning wheel 309 can tension the belt 305 to ensure that the belt 305 can stably drive the dehumidification wheel 302 to rotate.

[0058] In addition, a connecting ear 310 is connected to the tensioning wheel 309, a fixing frame 311 is connected to the partition plate 101, an ear plate is connected to the fixing frame 311, and several through holes are provided on the ear plate. By connecting the tension spring 312 into different through holes, the tension of the tension spring 312 on the tensioning frame 308 can be adjusted.

[0059] One of the through holes is connected to a tension spring 312 between the tension spring 312 and the fixing frame 311. The tension spring 312 is used to pull the tensioning frame 308 so that the tensioning wheel 309 can tension the belt 305.

[0060] like Figures 1 to 7 As shown, the regeneration heater 4 is installed on the partition 101 and located inside the second cavity 103. The regeneration heater 4 corresponds to the regeneration air vent 1012. The regeneration heater 4 is used to heat the air, so that the moisture in the dehumidification wheel 302 can be released, thereby restoring the moisture absorption capacity of the dehumidification wheel 302.

[0061] The regenerator 4 is equipped with a gas collecting hood 401 on its outer side, which covers part of the dry air vent 1011. Figure 5As shown, some of the air in the first cavity 102 enters the air collection hood 401 through the dehumidifying rotor 302 and the dry air vent 1011. Some of the air in the air collection hood 401 acts in the opposite direction on the regeneration heater 4, so that the hot air generated by the regeneration heater 4 can be blown towards the dehumidifying rotor 302 through the regeneration air vent 1012, so that the moisture in the dehumidifying rotor 302 can be released, thereby restoring the moisture absorption capacity of the dehumidifying rotor 302.

[0062] In practical use, such as Figure 1 As shown, two independent dry and wet air ducts are formed inside the housing 1. The dry air duct is left-in and right-out. That is, the air enters through the air inlet 104, is drawn into the first cavity 102 by the processing fan 201, and enters the upper 1 / 2 dehumidification wheel 302. The moisture in the air is adsorbed by the dehumidification wheel 302. The dried air passes through the dehumidification wheel 302 and enters the second cavity 103 through the dry air vent 1011, and is then discharged through the dry air duct 107.

[0063] The damp air duct enters from the left and exits from the left, such as... Figures 1 to 5 As shown, air is drawn into the first chamber 102 by the processing fan 201 through the air inlet 104. Part of the air in the first chamber 102 enters the air collection hood 401 through the dry air vent 1011 covered by the dehumidifying rotor 302 and the air collection hood 401. Part of the air in the air collection hood 401 acts in the opposite direction on the regeneration heater 4, allowing the hot air generated by the regeneration heater 4 to be blown towards the dehumidifying rotor 302 through the regeneration air vent 1012, releasing the moisture in the dehumidifying rotor 302. This moisture is then discharged through the regeneration air vent 303 and the regeneration air duct 106, thus restoring the dehumidifying rotor 302's moisture absorption capacity. This cycle continuously discharges humid and dry air, achieving the separation of wet and dry air and reducing air humidity. Compared to existing rotary dehumidifiers on the market, the rotary dehumidifier in this application has a simpler structure, which reduces production and labor costs, thereby increasing the profit margin of the rotary dehumidifier.
