Description

Technical Field

[0001] The invention relates to the technical field of rotary dehumidifiers, in particular to a tubular rotary dehumidifier for cold storage. Background Art

[0002] In the daily management of cold storage, humidity management of cold storage is a key factor in ensuring the quality of stored goods and extending the shelf life. Traditional dehumidification methods, such as refrigeration dehumidification or chemical desiccant, are often limited by high energy consumption, frequent maintenance or environmental pollution. Therefore, the use of rotary dehumidifiers has become a new choice for optimizing the cold storage environment.

[0003] After searching, the patent publication number CN219318558U discloses a rotary dehumidifier which is convenient for cleaning the rotary wheel, comprising: a main unit, which comprises a dehumidifier shell and a mounting plate installed in the dehumidifier, a corresponding rotary wheel cover is fixedly installed at the center of the upper side wall of the mounting plate, a dehumidification wheel is rotatably installed in the rotary wheel cover, a driving motor is fixedly installed on the upper side wall of the rotary wheel cover, and the output shaft of the driving motor is connected to the dehumidification wheel through a transmission belt; a rotary wheel cleaning unit, which comprises a liquid pipe fixedly installed on the side wall of the mounting plate and a cleaning frame connected to the liquid pipe, the mounting plate and the lower inner wall of the dehumidifier shell are separated into a water storage chamber and a sewage discharge chamber by a partition.

[0004] The prior art also has the following defects during use:

[0005] 1. In the daily use of the tubular rotary dehumidifier for cold storage in the prior art, after the rotary dehumidifier dehumidifies the air in the cold storage, it is necessary to dry the dehumidification material with hot air to discharge the absorbed moisture and restore the water absorption performance of the dehumidification material. However, the air temperature in the cold storage is relatively low. After the dehumidification material absorbs moisture and then undergoes hot air drying, it will be irreversibly and permanently damaged in the process of sudden cooling and heating, thereby losing the dehumidification function of the air. The dehumidification material needs to be replaced frequently, which not only reduces the practicality of the rotary dehumidifier, but also increases the cost of the later maintenance of the rotary dehumidifier.

[0006] 2. When the tubular rotary dehumidifier for cold storage in the prior art dehumidifies the air, since the rotary wheel rotates continuously during operation, the air with moisture on one side of the rotary wheel is easily exposed to hot air, resulting in the air with moisture being unable to be effectively dehumidified by the rotary dehumidifier, and then following the hot air exhaust device, reducing the efficiency of the rotary dehumidifier for air dehumidification.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] like Figure 1 - Figure 8As shown, a tubular rotary dehumidifier for cold storage proposed by the present invention comprises a first shell 1, a base 2, a rotary wheel assembly 3 and a second shell 4, the first shell 1 is fixedly installed on one side of the top of the base 2, a first partition 103 is fixedly installed inside the first shell 1, the base 2 is used to provide a mounting position for the components on the top, the first shell 1 can provide a mounting position for the components inside, and cooperates with the dehumidification cylinder 5 and the second shell 4 to form a cylindrical structure, so as to facilitate the transmission of air and then dehumidify the air;

[0036] A dehumidification cylinder 5 is installed on one side of the first shell 1 by bolts, and the two sides of the dehumidification cylinder 5 are respectively connected to the first shell 1 and the second shell 4 by bolts, thereby providing a mounting position for the wheel assembly 3, so that the wheel assembly 3 is connected with the inside of the first shell 1 and the second shell 4, so that the air is dehumidified after passing through the first shell 1, the dehumidification cylinder 5 and the second shell 4;

[0037] The dehumidification cylinder 5 is internally rotatably installed with a rotating wheel assembly 3, which can dehumidify the air entering the dehumidification cylinder 5, and the dehumidification disc 304 inside the rotating wheel assembly 3 continuously rotates during the dehumidification process to ensure the dehumidification effect of the rotating wheel assembly 3 on the air;

[0038] A second shell 4 is installed on the side of the dehumidification cylinder 5 away from the first shell 1 by bolts. The second shell 4 can cooperate with the first shell 1 and the dehumidification cylinder 5 to form a cylindrical structure, thereby guiding the air to flow inside the device, and then cooperating with the wheel assembly 3 to dehumidify the air entering the device.

[0039] Furthermore, the wheel assembly 3 includes a wheel drum 301, two dehumidification discs 304 are fixedly installed inside the wheel drum 301, a plurality of air holes are opened inside the dehumidification disc 304, and a central axis 305 is fixedly installed at the central position of the dehumidification disc 304. The thickness at the edge of the dehumidification disc 304 is less than the thickness near the central axis 305. The wheel drum 301 can provide a mounting position for the surrounding components. The wheel drum 301 can be connected to the conveyor belt, and the wheel drum 301 is connected to the drive shaft 203 through the transmission belt 202, so that the drive shaft 203 drives the wheel drum 301 to rotate when rotating. The dehumidification disc 304 is made of a polymer composite material mixed with polyacrylamide material and silica gel. The ratio of polyacrylamide material to silica gel in the dehumidification disc 304 is 3 :1. The dehumidification disk 304 can absorb moisture in the air, thereby achieving dehumidification of the air, and the dehumidification disk 304 is air-permeable, and can transmit the air from the air guide pipe 104 to the exhaust pipe 402 after dehumidification of the air. The dehumidification disk 304 adopts a structural design with a thick center and thin edges, which can guide the air so that the air flows to the edge position, and then dehumidifies the air through the dehumidification disk 304, avoiding a large amount of air with moisture to accumulate around the central axis 305, thereby preventing the air with moisture from contacting the hot air flow of the regenerated dehumidification disk 304 and affecting the dehumidification effect of the dehumidification disk 304 on the air. The two ends of the central axis 305 are respectively connected to the first mounting plate 105 and the second mounting plate, so that the rotor drum 301 can be rotated and the stability of the installation of the rotor assembly 3 is guaranteed;

[0040] A first mounting frame 306 is fixedly installed on one side of the rotating drum 301 close to the first shell 1. The first mounting frame 306 is an X-shaped structure. A first guide ring 303 is fixedly installed on the outer side of the first mounting frame 306. The X-shaped structure of the first mounting frame 306 includes a group of first guide covers 302 fixedly installed diagonally, and a plurality of guide holes are opened inside the first guide cover 302. The first mounting frame 306 is used to provide a mounting position for the first guide ring 303 and the first guide cover 302, so as to guide the air and divide the space on one side of the rotating drum 301 into regions to avoid hot air flow and cold air with moisture. The air contact affects the dehumidification effect of the rotor assembly 3. The first guide ring 303 is used to cooperate with the first mounting frame 306 to divide the space on one side of the rotor drum 301 into regions, so as to guide the air to flow around the rotor drum 301. The first guide cover 302 adopts a mesh structure with a plurality of square holes opened inside, which is used to guide the air to flow on one side of the rotor drum 301, so that the air can be evenly distributed on the surface of the dehumidification disk 304, and then the air is dehumidified by the dehumidification disk 304, so that the dehumidification disk 304 is evenly in contact with the air, so as to avoid the increase of local humidity in the dehumidification disk 304 and affect the dehumidification effect of the air;

[0041] A second mounting frame 307 is fixedly mounted on one side of the rotating drum 301 close to the second shell 4. The second mounting frame 307 is an X-shaped structure. A second guide ring 308 is fixedly mounted on the outer side of the second mounting frame 307. A plurality of ventilation holes are provided on both sides of a group of diagonals of the X-shaped structure of the second mounting frame 307. A second guide cover 310 is fixedly mounted between another group of opposite diagonals. A plurality of drainage pipes 309 are fixedly mounted on the bottom of the two plates on the upper part of the second mounting frame 307. The drainage pipes 309 are connected to the second mounting frame 307. A one-way valve is fixedly installed at the connection position of the second mounting frame 307, and the one-way valve is consistent with the ventilation hole inside the second mounting frame 307. A plurality of exhaust holes are opened on the side of the drainage pipe 309. The second mounting frame 307 is used to divide the area of ​​the side of the rotary drum 301 away from the first mounting frame 306, and provide a mounting position for the second guide ring 308, the drainage pipe 309 and the second guide cover 310. The second guide ring 308 cooperates with the second mounting frame 307 to close the rotary drum 301. The air on one side of the second shell 4 is guided so that the dehumidified air flows toward the exhaust pipe 402. The hot air flow for regenerating the dehumidification disk 304 enters the interior of the rotary drum 301 through the guide pipe 404 to dry the dehumidification disk 304 and restore the dehumidification performance of the dehumidification disk 304. The second guide cover 310 is used to guide the dehumidified air from the rotary drum 301 into the interior of the exhaust pipe 402, thereby preventing the dehumidified air from flowing upward and affecting the regeneration effect of the hot air flow on the dehumidification disk 304. The guide pipe 309 can guide the hot air flow to flow so that the hot air flow can be evenly dispersed to the areas on both sides of the dehumidification disk 304 while drying the dehumidification disk 304, heating the dehumidification disk 304, and then the dehumidification disk 304 is heated by the hot air flow before it comes into direct contact with the cold air flow, thereby avoiding irreversible permanent damage to the dehumidification disk 304 under sudden cooling and sudden heating, so as to ensure the durability of the dehumidification disk 304 and enable the dehumidification disk 304 to be reused.

[0042] Furthermore, a first mounting plate 105 is fixedly installed on one side of the first partition 103 close to the dehumidification cylinder 5, an exhaust pipe 102 is fixedly installed above the first partition 103, an exhaust pump 101 is fixedly installed inside the exhaust pipe 102, one end of the exhaust pipe 102 is fixedly connected to the first mounting plate 105, the first mounting plate 105 is used to provide an installation position for the exhaust pipe 102, the air duct 104, the first partition 103 and the central axis 305, thereby ensuring the installation stability of the exhaust pipe 102, the air duct 104 and the first partition 103, and can also limit the central axis 305 to ensure that the wheel assembly 3 can rotate stably. The exhaust pump 101 adopts the BPT15-33H55 type. The exhaust pipe 102 can suck the hot air flow through the exhaust pump 101, and then the hot air flow passes through the wheel assembly 3 into the exhaust pipe 102, so that the hot air flow drives the water vapor out of the device together.

[0043] Furthermore, a second partition 405 is fixedly installed inside the second shell 4, a second mounting plate is fixedly installed on one side of the second shell 4 close to the dehumidification cylinder 5, and the second mounting plate is fixedly connected to the second partition 405, a guide tube 404 is fixedly installed above the second partition 405, a heater 403 is fixedly installed inside the guide tube 404, and one end of the guide tube 404 is fixedly connected to the second mounting plate, and the second partition 405 is used to separate the space inside the second shell 4, thereby avoiding mutual interference between the airflows at the top and bottom of the second partition 405 when flowing. The two mounting plates can provide a fixed mounting position for the guide tube 404 and the exhaust tube 402, and limit one end of the central axis 305, so that the central axis 305 can stably rotate the wheel assembly 3 under the limitation of the first mounting plate 105 and the second mounting plate. The heater 403 adopts the UC-300-50S type. The heater 403 heats the air inside the guide tube 404 by electric heating, so that the air contacts the dehumidification disk 304 after heating, thereby achieving drying of the dehumidification disk 304, so as to restore the dehumidification performance of the dehumidification disk 304.

[0044] Furthermore, a driving shaft 203 is installed at the top of the base 2 near the front position through a bearing, and a transmission belt 202 is installed around the outside of the driving shaft 203. The transmission belt 202 extends to the inside of the dehumidification cylinder 5, and the other end of the transmission belt 202 is wrapped around the outside of the rotary drum 301. The driving shaft 203 is fixedly connected to the motor 201. When the motor 201 is powered on, it rotates to drive the driving shaft 203 to rotate, so that the driving shaft 203 drives the transmission belt 202 to roll, and the transmission belt 202 drives the rotary drum 301 to rotate, so as to drive the dehumidification disk 304 to rotate at a uniform speed.

[0045] Furthermore, an electric motor 201 is fixedly installed at one end of the driving shaft 203, and the bottom of the electric motor 201 is fixedly connected to the base 2. The electric motor 201 adopts the YE3-100KW type. The electric motor 201 can rotate after being energized, thereby driving the driving shaft 203 to rotate. The driving shaft 203 is then connected to the rotary drum 301 through the transmission belt 202, driving the rotary drum 301 to rotate at a uniform speed, so that the dehumidification disk 304 absorbs moisture inside the cold air flow after contacting with the cold air flow, and then by rotating the dehumidification disk 304, the dehumidification disk 304 that has absorbed moisture is contacted with the hot air flow, and then the dehumidification disk 304 is heated, so that the moisture absorbed by the dehumidification disk 304 is carried out of the device through the hot air flow, thereby realizing the recovery and regeneration of the dehumidification performance of the dehumidification disk 304.

[0046] Furthermore, an exhaust pipe 402 is fixedly installed below the second partition plate 405, and an exhaust fan 401 is fixedly installed inside the exhaust pipe 402, and one end of the exhaust pipe 402 is fixedly connected to the second mounting plate. The exhaust pipe 402 can allow the cold air flow that has been dehumidified in the cold storage to return to the cold storage again, so that the cold air flow returns to the cold storage after being dehumidified inside the device to achieve internal circulation. The exhaust fan 401 adopts DJT12-35B type. The exhaust fan 401 can suck the air inside the exhaust pipe 402, so that the cold air flow is dehumidified by the wheel assembly 3 and then flows back to the cold storage through the exhaust pipe 402.

[0047] Furthermore, an air duct 104 is fixedly installed below the first partition 103, and one end of the air duct 104 is fixedly connected to the first mounting plate 105. The air duct 104 can guide the cold air flow into the wheel assembly 3, thereby allowing the cold air flow with moisture to dehumidify through the wheel assembly 3, and then the dehumidified cold air flow enters the exhaust pipe 402 and flows back to the cold storage.

[0048] Working principle: After the device is assembled and confirmed to be correct, the air duct 104 and the exhaust pipe 402 are connected to the cold storage. After the motor 201 is powered on, it rotates to drive the drive shaft 203 to rotate. The drive shaft 203 drives the wheel drum 301 to rotate at a uniform speed through the transmission belt 202. The air pump 101 sucks the air inside the air duct 102. At the same time, the heater 403 heats the air inside the air duct 404 after being powered on, so that the hot air flow passes through the dehumidification disk 304 and enters the air duct 102 for discharge. After the exhaust fan 401 is powered on, it sucks the cold air flow in the cold storage, so that the air in the cold storage enters the inside of the wheel assembly 3 through the air duct 104 and passes through the first air guide cover 3 02, the cold air flow contacts the dehumidification disk 304, the dehumidification disk 304 absorbs the moisture inside the cold air flow, and the dehumidified cold air flow enters the exhaust pipe 402 under the guidance of the second air guide cover 310, and the dehumidified cold air flow returns to the cold storage, so that the cold air flow in the cold storage circulates into the device for dehumidification, and the dehumidification disk 304 after absorbing moisture rotates and contacts the hot air flow, and the hot air flow heats the dehumidification disk 304 to evaporate the moisture absorbed by the dehumidification disk 304, and the moisture is discharged from the device together with the hot air flow through the exhaust pipe 102, and the dried dehumidification disk 304 rotates again, contacts the cold air flow again, so that the dehumidification disk 304 continues to dehumidify the cold air flow.
