Description

Technical Field

[0001] This utility model relates to the field of ventilation technology for warehouse sheds, and in particular to an environmentally friendly ventilation and air exchange mechanism for warehouse sheds. Background Technology

[0002] Storage sheds are widely used for the temporary or long-term storage of agricultural products, industrial raw materials, and other materials. The ventilation inside the sheds directly affects the quality of the stored materials, such as preventing agricultural products from becoming moldy and industrial raw materials from getting damp.

[0003] The ventilation and air exchange mechanisms of existing storage sheds are usually fixed in terms of ventilation angle, allowing ventilation only in one direction. This makes it difficult to adjust the ventilation angle and direction according to ventilation needs, thus making it difficult to achieve good ventilation results. Furthermore, the air inlets of existing ventilation and air exchange mechanisms are usually equipped with only a single-layer filter, which is insufficient to effectively intercept and absorb impurities and odors in the inhaled air, thus failing to meet environmental protection requirements.

[0004] Therefore, an environmentally friendly ventilation and air exchange mechanism for storage sheds is proposed. Utility Model Content

This mechanism solves the problems of existing ventilation and air exchange mechanisms for storage sheds, which typically have a fixed ventilation angle and can only ventilate in one direction. This makes it difficult to adjust the ventilation angle and direction according to ventilation needs, thus making it difficult to achieve good ventilation results. Furthermore, the air inlet of existing ventilation and air exchange mechanisms usually only has a single-layer filter, which is not enough to effectively intercept and absorb impurities and odors in the inhaled air, thus failing to meet environmental protection requirements.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] An environmentally friendly ventilation and air exchange mechanism for a storage shed includes a ventilation shell 1, a ventilation component 2 disposed on the front side of the inner cavity of the ventilation shell 1, and a filter component 3 disposed on the rear side of the ventilation shell 1.

[0028] The ventilation assembly 2 includes a fixed plate 21. The two sides of the fixed plate 21 are fixedly connected to the two sides of the inner wall of the ventilation housing 1. A first stepper motor 22 is fixedly connected to the rear side of the fixed plate 21. The output shaft of the first stepper motor 22 passes through the fixed plate 21 and is fixedly connected to a U-shaped frame 23. An adjusting rod 24 is provided in the inner cavity of the U-shaped frame 23. The two sides of the adjusting rod 24 pass through to the two sides of the U-shaped frame 23 respectively. A second stepper motor 25 is fixedly connected to the right side of the inner side of the U-shaped frame 23. A transmission gear 26 is fixedly connected to the output shaft of the second stepper motor 25. A driven gear 27 is meshed with the front side of the transmission gear 26. The driven gear 27 is fixedly connected to the surface of the adjusting rod 24. Transmission plates 28 are fixedly connected to both sides of the surface of the adjusting rod 24. A fan 29 is fixedly connected to the front side of the two transmission plates 28.

[0029] In this embodiment: by setting up a ventilation shell 1, a ventilation component 2, and a filter component 3, the ventilation shell 1 provides a ventilation duct during use. The ventilation component 2 delivers air into the storage shed, achieving ventilation and air exchange. The angle and direction of the air delivery can be easily adjusted, effectively increasing the air delivery range and thus improving the ventilation effect. The filter component 3 performs multiple filtration, interception, and adsorption of impurities and odors in the intake air during ventilation, preventing dust from adhering to the surface of materials or harmful gases from causing the deterioration of some special materials, thereby meeting environmental protection requirements.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the filter assembly 3 includes a fixed shell 31, which is fixedly connected to the rear side of the ventilation shell 1. From back to front, a coarse filter plate 32, a fine filter plate 33, and a honeycomb activated carbon plate 34 are sequentially inserted into the inner cavity of the fixed shell 31. The coarse filter plate 32, the fine filter plate 33, and the honeycomb activated carbon plate 34 are respectively in contact with the inner wall of the fixed shell 31 on one side close to the inner wall of the fixed shell 31.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the right side of the fixed shell 31 is provided with a pull-out opening 35 for use with the coarse filter plate 32, the fine filter plate 33 and the honeycomb activated carbon plate 34. A sealing cover 36 is provided on the right side of the pull-out opening 35. The bottom of the sealing cover 36 is rotatably connected to the right side of the bottom of the fixed shell 31 through a steering shaft, and the top of the sealing cover 36 is snapped into the right side of the top of the fixed shell 31 through a latch.

[0032] Specifically, such as Figure 2 , Figure 5 , Figure 6As shown, limit bars 37 are fixedly connected to the front and rear sides of the top and bottom of the inner wall of the fixed shell 31. The four limit bars 37 are respectively close to the coarse filter plate 32 and the honeycomb activated carbon plate 34 and are in contact with the coarse filter plate 32 and the honeycomb activated carbon plate 34.

[0033] In this embodiment: by setting up a fixed shell 31, a coarse filter plate 32, a fine filter plate 33, a honeycomb activated carbon plate 34, a pull-out opening 35, a sealing cover 36, and a limiting strip 37, during ventilation, external air first enters the fixed shell 31. At this time, the coarse filter plate 32 inside the fixed shell 31 first intercepts large particles of dust in the air, such as sand, fallen leaf debris, etc., and then the fine filter plate 33 further filters fine particulate matter, such as PM2.5, pollen, etc. Finally, the honeycomb activated carbon plate 34 adsorbs odors and harmful gases, such as volatile organic compounds and mold spores in humid air, thereby achieving multiple filtration and interception of impurities and odors in the inhaled air. The adsorption process can prevent dust from adhering to the surface of materials or harmful gases from causing some special materials to deteriorate, thus meeting environmental protection requirements. When it is necessary to clean or replace the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34, simply open the sealing cover 36 and then pull the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34 out of the fixed shell 31 through the pull-out port 35, which is quite convenient. The position of the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34 can be limited by the setting of the limiting bar 37 to prevent the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34 from moving.

[0034] Specifically, such as Figure 4 As shown, the rear side of the fixing plate 21 is provided with a first through hole 4 for use with the first stepper motor 22, and the output shaft surface of the first stepper motor 22 is rotatably connected to the inner wall of the first through hole 4 through a bearing.

[0035] Specifically, such as Figure 4 As shown, the front sides of both sides of the U-shaped frame 23 are provided with second through holes 5 for use with adjusting rods 24. The two sides of the surface of the adjusting rods 24 are rotatably connected to the inner walls of the two second through holes 5 through bearings.

[0036] In this embodiment: by providing the first through hole 4, the output shaft of the first stepper motor 22 can pass through the fixed plate 21 and rotate easily through the bearing; by providing the second through hole 5, the adjusting rod 24 can pass through the U-shaped frame 23 and rotate easily through the bearing.

[0037] Specifically, such as Figure 1 , Figure 2As shown, a controller 6 is fixedly connected to the bottom of the front right side of the ventilation housing 1. The controller 6 is used in conjunction with the first stepper motor 22, the second stepper motor 25 and the fan 29. The controller 6 is electrically connected to the first stepper motor 22, the second stepper motor 25 and the fan 29.

[0038] Specifically, such as Figure 2 As shown, a wind speed sensor 7 is fixedly connected to the right side of the inner wall of the ventilation housing 1, and the wind speed sensor 7 is electrically connected to the controller 6.

[0039] In this embodiment: by setting the controller 6, the first stepper motor 22, the second stepper motor 25 and the fan 29 can be controlled to work. By setting the wind speed sensor 7, the ventilation wind speed can be detected in real time and the wind speed data can be fed back to the controller 6.

[0040] Working Principle: In use, the ventilation housing 1 is first fixedly installed in the ventilation window of the storage shed or other suitable location using bolts and other fasteners. During ventilation, the fan 29 can be started via the controller 6. External air first enters the fixed housing 31. Large particles of dust, such as sand and leaf debris, are intercepted by the coarse filter plate 32 inside the fixed housing 31. Then, fine particles, such as PM2.5 and pollen, are further filtered by the fine filter plate 33. Finally, odors and harmful gases, such as volatile organic compounds and mold spores in humid air, are adsorbed by the honeycomb activated carbon plate 34. This multi-stage filtration and adsorption process effectively removes impurities and odors from the inhaled air, preventing dust from adhering to the surface of materials or harmful gases from causing deterioration of certain materials, thus meeting environmental protection requirements. When cleaning or replacing the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34, simply turn on the button... Open the sealing cover 36, and then pull out the coarse filter plate 32, fine filter plate 33, and honeycomb activated carbon plate 34 from the fixed shell 31 through the pull-out port 35. This is quite convenient. Then, the purified air will pass through the ventilation shell 1 and be blown into the storage shed to achieve ventilation and air exchange in the storage shed. At the same time, the angle and direction adjustment parameters of the fan 29 can be set through the controller 6. Then, the output shaft of the second stepper motor 25 drives the transmission gear 26 to rotate. The transmission gear 26 drives the driven gear 27 that meshes with it to rotate. The driven gear 27 drives the adjusting rod 24 to rotate. The adjusting rod 24 drives the transmission plate 28 to rotate. The transmission plate 28 drives the fan 29 to rotate, thereby adjusting the up and down air delivery angle of the fan 29. Then, the output shaft of the first stepper motor 22 drives the U-shaped frame 23 to rotate, thereby adjusting the air delivery direction of the fan 29, thus effectively increasing the air delivery range and improving the ventilation effect.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
