Description

Technical Field

[0001] The utility model relates to the field of humidifying devices, in particular to a novel wet film humidifying device. Background Art

[0002] There are two main types of wet film humidification devices available: powered and unpowered. Powered wet film humidification devices use a power source, such as a water pump, to apply water to the wet film. However, since the water pump applies water downward from the top of the wet film, the evaporation rate is much lower than the applied water. Unpowered wet film humidification devices place the lower end of a water-absorbing wet film in water, where the film retains moisture due to its inherent water absorption. Chinese patent application CN206695312U discloses a humidification membrane device comprising a water absorption trough, a water receiving trough, and a self-priming wet film. The water absorption trough is positioned higher than the water receiving trough. One end of the self-priming wet film is immersed in water in the water absorption trough, while the other end is placed in a water receiving tray. However, in the existing unpowered wet film humidification device, it takes a long time for the wet film to be completely soaked after the equipment is started. The moisture carried in the airflow driven by the fan can stably humidify the target environment. The preparation time before the equipment humidifies is long, and the existing airflow has a large resistance when passing through the wet film. Long-term use can easily cause contamination to the wet film. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0025] like Figures 1 to 8 In one embodiment of the novel wet-film humidification device of the present invention, a water collection chamber 2 is provided within a housing 1, connected to a water pump 14 via a pipeline. An air inlet 11 for airflow and an air outlet 12 for airflow are provided on the upper sidewall of the housing 1. The device is characterized in that the water collection chamber 2 is provided with an immersion device 3 for infiltrating the airflow, and a humidifying fan 4 whose air outlet is connected to the air outlet 12. The immersion device 3 includes a plurality of spaced-apart wet-film racks 6, and an oscillating device 5 that drives the plurality of wet-film racks 6 to swing in a parallel four-bar linkage configuration while submerged in the accumulated water below. The wet-film racks 6 include a support frame 61 for mounting the wet film. By designing multiple wet-film racks that can simultaneously form a parallel four-bar linkage configuration, the airflow is humidified while the wet film is rapidly infiltrated upon initial startup, ensuring rapid and stable humidification efficiency upon initial startup.

[0026] Specifically, the upper part of the support frame 61 is provided with an upper hinge shaft 62 hinged on the inner wall of the shell 1, and the lower part is provided with a lower hinge shaft 63 hinged on the inner wall of the shell 1; the swing device 5 includes a connecting rod 51 for hinged connection of multiple upper hinge shafts 62, an electric actuator 52 arranged on the outside of the shell 1, and a rocker arm 53 whose ends are respectively hinged on the electric actuator 52 and the connecting rod 51; the rocker arm 53 can drive the connecting rod 51 to maintain a horizontal direction at all times and swing.

[0027] Specifically, the connecting rod 51 is provided with a first hinge shaft 54 hingedly connected to a rocker arm 53. The rocker arm 53 is provided with a sliding hole 55 for the sliding of the first hinge shaft 54 and a slider 56 for pushing the first hinge shaft 54. The rocker arm 53 is provided with a slideway 57 for the sliding of the slider 56 and a support spring 58 disposed within the slideway 57 for pushing the slider 56. By designing a rocker arm that can slide and push the hinge shaft, the wet film racks are smoothly moved and pushed, ensuring that the multiple wet film racks swing in a parallel four-bar linkage manner and are always parallel.

[0028] Specifically, multiple wet film racks 6 are enclosed to form an air flow channel that is connected in an S-shaped bend from head to tail; one side of the support rack 61 is set close to the inner wall of the shell 1, and the other side is set apart from the side wall of the shell 1; adjacent support racks 61 are respectively close to the two opposite side walls of the shell 1.

[0029] Specifically, a plurality of S-shaped guide frames 64 are connected end to end on the support frame 61. The reciprocating bending guide frames ensure smooth passage of airflow, reduce direct resistance to airflow, and maximize the contact between airflow and wet film to ensure the wetting efficiency of airflow.

[0030] Specifically, an air inlet cover 13 is provided on the air inlet hole 11; a filter screen for filtering impurities in the air flow is provided in the air inlet cover 13. The preset filter screen retains impurities in the air flow, reducing the damage of impurities in the air to the wet film.

[0031] Specifically, the humidification fan 4 is a turbine blower with its air inlet facing downward. A "J"-shaped bracket is installed within the water collection chamber 2 to support the humidification fan 4 within its upper inner cavity. This "J"-shaped bracket stably supports the humidification fan 4 within the upper inner layer of the water collection chamber 4, with the air inlet positioned below the humidification air, ensuring contact between the airflow path and the wet film, thus ensuring humidification efficiency.

[0032] Specifically, a liquid level measuring device for measuring the liquid level in real time is provided in the water collecting tank 2. The liquid level measuring device may be a float level gauge.

[0033] Specifically, a liquid level observation hole 21 is vertically provided on the side wall of the water collecting bin 2 .

[0034] Working principle: Before starting the equipment, the staff can first fill water into the bottom of the water collection bin 2, which can be observed through the liquid level observation hole 21. The water level will stop after reaching the target water level. After starting the equipment, the electric actuator 52 drives the rocker arm 53 to swing, and the swing 53 drives the connecting rod 51 to move downward. During the movement, the first hinge shaft 54 pushes the slider 56 and shrinks it into the slide 57. After the support spring 58 is compressed to the shortest length, the support spring 58 pushes the slider 57 and further pushes the first hinge shaft 54 during the downward swing, driving the wet film rack 6 to swing downward. Multiple spaced wet film racks 6 are arranged in parallel, driving multiple spaced wet film racks 6 to swing in a parallel four-link type. After the wet film rack 6 swings to the lowest position, it is completely immersed in the pre-selected injected water flow. The electric actuator The device 52 drives the rocker arm 53 to swing in the opposite direction. After the wet film rack 6 returns to the vertical position, the electric actuator 52 stops swinging, and the humidifying fan 4 starts synchronously to drive the airflow to circulate. A sealing plate is provided on the top cover of the shell to block the gap between multiple wet film racks 6 and the top cover to ensure that the airflow passes completely through the infiltration device 3. The liquid level meter in the water collecting bin 2 measures the liquid level in real time. After the liquid level drops to the preset position of the controller, the controller starts the water pump 11 to fill water into the water collecting bin, and disconnects the water pump 11 after reaching the target water level; after a period of use, the humidifying fan 4 is turned off, and the electric actuator 52 drives the wet film rack 6 to repeat the above operation to immerse it downward in the accumulated water, flush the surface of the wet film, reduce impurities contaminated by the wet film, and restart the humidifying fan 4 after the wet film rack 6 swings upward to the vertical position again.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
