Description

Technical Field

[0001] The utility model relates to the technical field of grain storage, in particular to a water-retaining, ventilation-regulating fan specially used for granaries. Background Art

[0002] Chinese patent application number 201220087386.0 discloses a grain storage and conditioning machine for large granaries, which includes a fan, a water pump, a ventilation and water storage plate, a sprinkler pipe and a frame. The bottom of the frame serves as a circulating water pool, which is connected to a water inlet pipe and a drain pipe. The top of the frame is provided with an air outlet pipe, and the fan is installed in the air outlet pipe. Ventilation and water storage plates are provided on three sides of the frame, and a sprinkler pipe is provided directly above the ventilation and water storage plates. The sprinkler pipe is connected to the water outlet of the water pump, and the water inlet of the water pump is connected to the bottom of the frame. During use, the air outlet pipe of the conditioning machine is introduced into a controlled environment (such as a granary) through a ventilation pipe. External water is passed from the water inlet pipe of the bottom shell to the circulating water tank, then to the water pump, then to the sprinkler pipe, and finally to the ventilation water storage plate. The ventilation water storage plate absorbs water and forms a ventilation water film with ventilation holes. Dry air outside the frame, driven by the fan, passes through the ventilation holes of the ventilation water film, and is humidified by the ventilation water film into wet air. Then, it enters the controlled environment through the air outlet pipe, and finally enters the ventilation pipe, thereby providing moisture-retaining ventilation treatment in the controlled environment. Existing conditioning machines have the disadvantages of being non-compact in structure and the contact time between dry air and the ventilation water film is too short, which limits the humidification effect on the dry air, affecting the moisture-retaining ventilation effect of the controlled environment. Therefore, improvements are needed. Summary of the Invention

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] refer to Figures 1 to 5 A water-retaining ventilation and control fan specially designed for granaries comprises a cylindrical shell 1, wherein the upper portion of the shell 1 has a ventilation chamber 11, and the lower portion has a mechanical chamber 12; the top of the ventilation chamber 11 has an air inlet 13, and the air inlet 13 is provided with a filter 131 that blocks the air inlet 13. An air outlet 14 is provided on one side of the mechanical chamber 12, and the ventilation chamber 11 and the mechanical chamber 12 are separated by a transverse partition 15, and the transverse partition 15 has a connecting port arranged opposite the air inlet 13. A fan body 2 is provided in the mechanical chamber 12, and the air inlet end of the fan body 2 is connected to the connecting port, and the air outlet end is connected to the air outlet 14.

[0028] A wet curtain assembly is provided in the ventilation cavity 11. The wet curtain assembly is a cylindrical structure formed by a ring-shaped arrangement of multiple rectangular or arc-shaped honeycomb wet curtain plates 3, with a vertical wet curtain through hole 31 in the middle. In this embodiment, the wet curtain assembly is specifically arranged using four rectangular honeycomb wet curtain plates 3. The wet curtain through hole 31 is coaxially arranged with the air inlet 13 and the connecting port, and the inner diameter of the wet curtain through hole 31 is larger than the inner diameter of the air inlet 13 and the connecting port, so that the honeycomb wet curtain plates 3 of the wet curtain assembly are staggered from the air inlet 13 and the connecting port. A return air cavity 111 is provided between the outer side surface of the wet curtain assembly in the ventilation cavity 11 and the inner wall of the shell 1, and a return air gap 112 is provided between the top of the wet curtain assembly and the inner wall of the shell 1. The return air cavity 111 is connected to the wet curtain through hole 31 through the return air gap 112.

[0029] The honeycomb wet curtain 3 has a plurality of ventilation holes 32 arranged in a honeycomb pattern. In this embodiment, the ventilation holes 32 are arranged horizontally. A spray component 4 is provided above the honeycomb wet curtain 3. The spray component 4 has spray holes (not shown) positioned directly opposite the honeycomb wet curtain 3. The spray component 4 is connected to a water injection pipe 41, the end of which extends through the ventilation cavity 11. An annular water baffle 5 is provided at the communication opening within the ventilation cavity 11. A water collection chamber 51 is formed between the annular water baffle 5 and the inner wall of the housing 1. The bottom of the wet curtain assembly is located within the water collection chamber 51.

[0030] In the above structure, the air outlet 14 is used to connect the ventilation system of the granary, and is connected to the tap water pipe or the water injection pump 8 and the water tank 6 described below through the water injection pipe 41. Water is sprayed from the water injection pipe 41 → the spray component 4 → the spray hole to the honeycomb wet curtain plate 3, soaking the honeycomb wet curtain plate 3, and the excess water falls into the water collection chamber 51. After spraying for a period of time, the fan body 2 is turned on to pass the dry air from the outside through the air inlet 13 → the wet curtain through hole 31, as shown in the following figure. Figure 3 A part of the dry air directly carries the wet air in the wet curtain through hole 31 → the connecting port, and the other part of the dry air goes from the wet curtain through hole 31 → the ventilation hole 32 → the return air cavity 111 → the return air gap 112 → the wet curtain through hole 31 → the connecting port. The above two parts of wet air carrying water vapor are transported to the granary through the fan body 2 → the air outlet 14.

[0031] In the above structure, firstly, the air inlet 13, the wet curtain through hole 31, and the communication port are coaxially arranged, and the honeycomb wet curtain panels 3 of the wet curtain assembly are staggered with the air inlet 13 and the communication port. This reduces the airflow resistance formed by the fan body 2, allowing for efficient and rapid delivery into the granary. Secondly, an air circulation channel is formed from the wet curtain through hole 31 → the ventilation hole 32 → the return air cavity 111 → the return air gap 112 → the wet curtain through hole 31, effectively increasing the contact time between the air and the wet curtain assembly, thereby effectively increasing the air humidity and achieving efficient and environmentally friendly ventilation.

[0032] Furthermore, an annular air guide plate 16 is provided on the air inlet 13 within the ventilation cavity 11. The bottom end of the annular air guide plate 16 is located within the top end of the wet curtain through hole 31 of the wet curtain assembly. In this structure, the annular air guide plate 16 appropriately isolates the airflow flowing into the wet curtain through hole 31 from the airflow flowing into the wet curtain through hole 31 through the return air gap 112, guiding the airflow to quickly enter the wet curtain through hole 31, thereby ensuring rapid flow of air along the above-mentioned air circulation channel.

[0033] Furthermore, the spray component 4 is a horizontally arranged long tubular structure and is arranged above the honeycomb wet curtain plate 3. In this embodiment, the spray components 4 of two adjacent honeycomb wet curtain plates 3 are interconnected to form two L-shaped long tubular spray components 4, each of which is connected to a water injection pipe 41. This structure is more compact, reduces pipe connections, and ensures efficient water supply.

[0034] Furthermore, the mechanical chamber 12 is provided with a vertical partition 121, which divides the mechanical chamber 12 into a fan chamber on one side of the communication port and a water storage chamber on the other side. The fan body 2 is located in the fan chamber, and the air outlet 14 is located on one side of the fan chamber. The water storage chamber is provided with a water tank 6. The water collection chamber 51 is connected to the water tank 6 via a water outlet pipe 52. The water tank 6 is also connected to a water inlet pipe 61 and a drain pipe 62. In this structure, excess water in the water collection chamber 5 is directed to the water tank 6 for temporary storage via the water outlet pipe 52. The water tank 6 is then filled and drained via the water inlet pipe 61 and the drain pipe 62, respectively.

[0035] Furthermore, the water collecting chamber 51 is connected to the water outlet pipe 52 via the drainage pump 7. The drainage pump 7 is placed in the water collecting chamber 51, and the water inlet end of the drainage pump 7 is connected to the water collecting chamber 51, and the water outlet end of the drainage pump 7 is connected to the water outlet pipe 52. In the above structure, the drainage pump 7 is used to forcibly guide the excess water in the water collecting chamber 5 into the water tank 6 for temporary storage.

[0036] Furthermore, a water injection pump 8 is provided in the water storage chamber, the water inlet of the water injection pump 8 being connected to the water tank 6 and the water outlet being connected to the water injection pipe 41. In the above structure, the water in the water tank 6 is transported to the spray component 4 through the water injection pipe 41 by the water injection pump 8 for wetting the honeycomb wet curtain 3.

[0037] Furthermore, a temperature and humidity sensor 9 is provided in the ventilation cavity 11 for monitoring the humidity and temperature of the air in the ventilation cavity 11 .

[0038] Furthermore, a control center 91 for ventilation and humidity adjustment is provided in the middle of the front of the housing 1, and the fan body 2, the drainage pump 7, the water injection pump 8, and the temperature and humidity sensor 9 are electrically connected to the control center respectively.

[0039] When the water-retaining ventilation and control fan of this embodiment is in use, the air outlet 14 is connected to the granary through the ventilation pipe of the ventilation system, water is injected into the water tank 6 through the water inlet pipe 61, and the water injection pump 8 is controlled by the control center 91 to extract water from the water tank 6. The water injection pump 8 transports the water to the spray component 4, thereby spraying the water onto multiple honeycomb wet curtains 3, controlling the operation of the fan body 2, and the fan body 2 absorbs air. When the airflow passes through the honeycomb wet curtain 3, it will carry water vapor, thereby transporting the water vapor into the granary, effectively regulating the humidity inside the granary and improving the safety of grain storage.

[0040] Example 2

[0041] refer to Figure 6 and Figure 7 This embodiment differs from Example 1 in that the ventilation holes 32 on each honeycomb wet curtain plate 3 are arranged at an angle, extending diagonally downward from the inner side of the wet curtain assembly to the outer side of the wet curtain assembly. The inclination angle of the ventilation holes 32 relative to the horizontal plane is a, where 0°<a≤60°a. The inclination angle a of the ventilation holes 32 in this embodiment is specifically 55°. The oblique arrangement of the ventilation holes 32 in this embodiment reduces the resistance to airflow entering the ventilation holes 32 from the wet curtain through-holes 31, further facilitating the rapid entry of airflow into the aforementioned air circulation channel, effectively ensuring gas flow rate and maintaining efficient and reliable ventilation efficiency.
