Description

Technical Field

[0001] The utility model belongs to the technical field of humidifying devices, and in particular relates to an air supply device with adjustable humidity. Background Art

[0002] Humidity is a critical factor in grain storage. A suitable humidity environment is crucial for maintaining grain quality and storage stability. However, in some conditions, such as dry winters, low humidity can lead to excessive moisture loss in grain, affecting germination rate, processing quality, and nutritional content.

[0003] Humidification technology prevents grain from drying out and causing excessive moisture loss, which can affect its quality and weight. It also prevents breakage and cracking caused by drying, and reduces natural grain losses during storage. Humidification also helps maintain the physiological activity of grain, allowing it to better preserve its germination properties during storage.

[0004] In the prior art, devices that can humidify the air include ultrasonic humidifiers, evaporative humidifiers, thermal evaporative humidifiers, and pure humidifiers. Most of the above-mentioned humidifying devices use motor drivers to atomize water and use the mist to humidify the air. However, clear water will appear during the atomization and humidification process of the water, and too much clear water will have an adverse effect on grain storage. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an air supply device with adjustable humidity, which is used to solve the technical problem that the current humidification device humidifies the water by atomizing the water liquid and then introducing it into the air, resulting in the generation of visible water which has an adverse effect on grain storage.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a humidity-adjustable air supply device, which includes a shell, a wet membrane component, an ultrasonic atomizer and an air blower, the wet membrane component is arranged at an opening on one side wall of the shell, and a water retaining component is provided on the side of the wet membrane component away from the opening, and the air passing through the wet membrane component hits the water retaining component to intercept the clear water in the air; the air blower is arranged on the side of the water retaining component away from the wet membrane component, and the air outlet of the air blower extends out of the shell; the ultrasonic atomizer is arranged at the top of the shell above the wet membrane component, and the water outlet pipe of the ultrasonic atomizer discharges atomized gas for replenishing water for the wet membrane component.

[0007] Preferably, the water retaining assembly includes a guide ring connected to the wet membrane assembly and a water retaining plate provided in a gap with the guide ring. The water retaining plate is provided parallel to the wet membrane assembly and is larger than an opening of the guide ring.

[0008] Preferably, the guide ring is conical, and the opening at one end close to the water baffle is smaller than that at the other end.

[0009] Preferably, a ventilation channel exists between each edge of the water baffle and the corresponding side wall of the shell.

[0010] Preferably, the wet membrane assembly includes a supporting frame, multiple layers of wet membranes connected within the supporting frame, and air distribution pipes arranged on the top of the supporting frame and corresponding to each layer of the wet membrane, and the air distribution pipes are connected to the water outlet pipe.

[0011] Preferably, a buffer spring is provided between adjacent wet films.

[0012] The beneficial effects of adopting the technical solution of this utility model are:

[0013] The wet membrane component of the utility model replenishes water through the water vapor atomized by the ultrasonic atomizer, reduces the generation of clear water at the wet membrane component, and humidifies the air after the air passes through the wet membrane component, ensuring the uniformity of humidification. After the air passes through the wet membrane component, it hits the water retaining component, further intercepting the generated clear water, thereby preventing the clear water from entering the grain storage space and reducing the adverse effects of the clear water on grain storage.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0020] The specific embodiments are as follows:

[0021] Example 1, as Figure 1 、 2 As shown, a humidity-adjustable air supply device includes a housing 1, a wet film assembly 2, a water retaining assembly 3, an ultrasonic atomizer 5, and a blower 4. An opening 11 is provided on one side wall of the housing 1, and an air outlet is provided on the other side wall opposite the opening 11. The air outlet is connected to the air inlet 41 of the blower 4. The air outlet of the blower 4 extends outside the housing 1.

[0022] The wet membrane component 2 is arranged in the shell 1 close to the opening 11. The air in the storage room enters the shell 1 from the opening, and is sucked by the blower 4 and then discharged from the air outlet. During the process, the air passes through the wet membrane component 2 and comes into contact with the water vapor on the wet membrane component 2, increasing the air humidity, and then increasing the air humidity in the storage room.

[0023] A water retaining assembly 3 is provided on the side of the wet membrane assembly 2 away from the opening 11, which is provided on one side of the wet membrane assembly 2. After the air passes through the wet membrane assembly 2, it will hit the water retaining assembly 3. If there is clear water in the air, the clear water will flow down along the water retaining assembly 3, thereby preventing the clear water in the wet air from entering the storage chamber.

[0024] The ultrasonic atomizer 5 is disposed on the top of the housing 1 and above the wet membrane assembly 2. The outlet pipe 51 of the ultrasonic atomizer 5 extends into the housing 1 and is used to transport the atomized water vapor to the wet membrane assembly 2. The wet membrane assembly 2 uses capillary action to evenly absorb the mist droplets, increasing the humidity of the air passing through.

[0025] In this embodiment, the ultrasonic atomizer 5 is further provided with a water inlet pipe 52. A first valve is provided on the water inlet pipe 52 to control the opening and closing of the water inlet pipe 52 for replenishing water to the ultrasonic atomizer 5. A second valve is provided on the water outlet pipe 51, and a filter element is provided in the water outlet pipe 51 to filter dust or large particles to prevent clogging of the pipe.

[0026] In this embodiment, the air supply device further includes a sensor and a controller for detecting the ambient humidity in the storage room and controlling the start and stop of each part.

[0027] When the humidity-adjustable air supply device of this embodiment is in use, according to the detected air humidity of the storage room, when the humidity value is less than or equal to the preset threshold value, the second valve is opened, the ultrasonic atomizer 5 atomizes water into water vapor, and the outlet pipe 51 transports the atomized water vapor to the wet membrane assembly 2. The wet membrane assembly 2 absorbs the water vapor, and the air in the storage room passes through the wet membrane assembly 2 through the opening 11 and enters the shell 1 through the suction action of the blower 4. The humidity of the air entering the shell 1 increases, and then it is discharged from the storage room through the air outlet of the blower 4, completing the humidification of the air in the storage room and achieving humidity regulation. In this way, the atomized water vapor enters the wet membrane assembly 2, avoiding the formation of too much clear water on the wet membrane assembly 2. After passing through the wet membrane assembly 2, the air first hits the water retaining assembly 3. At this time, if the water content in the air is too high, the clear water left after the collision flows down from the water retaining assembly 3, preventing the clear water from entering the storage room and causing adverse effects on the stored grain.

[0028] Furthermore, the water retaining assembly 3 includes a guide ring 31 and a water retaining plate 32. The guide ring 31 is connected to the wet membrane assembly 2 and is sealed along the edge of the wet membrane assembly 2 to form a ring shape, which has a guiding effect on the air passing through the wet membrane assembly 2. The water retaining plate 32 is arranged parallel to the wet membrane assembly 2, and there is a gap between it and the guide ring 31, and the water retaining plate 32 is larger than the opening of the guide ring 31. The air passes through the wet membrane assembly 2 and hits the water retaining plate 32 under the guidance of the guide ring 31. After the collision, it flows into the right space in the shell 1 and enters the blower, so that the clear water in the air is stopped on the water retaining plate 32, preventing the clear water from entering the storage room and affecting the grain.

[0029] Furthermore, the guide ring 31 is conical, with a larger opening on the side close to the wet membrane assembly 2 and a smaller opening on the side close to the water baffle 32 , which helps the flowing air to converge toward the middle and ensure that it hits the water baffle 32 .

[0030] Furthermore, the guide ring 31 and the water baffle 32 are connected by a plurality of connecting columns, and there are gaps between each edge of the water baffle 32 and each corresponding side wall of the shell 1 to ensure that air can pass through.

[0031] Furthermore, the wet film assembly 2 includes a support frame 22, a wet film 21, and an air distribution pipe 23. The wet film 21 is arranged in multiple layers, arranged in parallel, and embedded between the support frame 22. Slits corresponding to each layer of wet film 21 are provided at the top of the support frame 22. Air distribution pipes 23 are installed within these slits. Air supply holes are provided on the underside of the air distribution pipes 23 to facilitate the flow of atomized water vapor onto the wet film 21. The air distribution pipes 23 are connected to the water outlet pipe 51 of the ultrasonic atomizer 5. The multiple layers of wet film 21 arranged in parallel create resistance to air, reducing air flow rate.

[0032] In this embodiment, the wet film 2 can be an organic wet film, an inorganic wet film, an aluminum alloy mesh wet film, a stainless steel perforated wet film, a ceramic wet film, etc., which can have strong water absorption and good self-cleaning ability, and is non-toxic, acid and alkali resistant, mildew resistant and flame retardant, and can provide the largest contact surface area between water and air.

[0033] Furthermore, buffer springs are provided between the layers of wet film 21 to provide elastic buffering to prevent the layers of wet film 21 from shaking and sticking together.

[0034] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
