Technical Field

The utility model relates to the technical field of food storage, in particular to a ventilation device used in a food storage warehouse.

Background Art

A warehouse is a general term for buildings and places for keeping and storing items. Generally, ventilation devices are installed in the warehouse to ensure ventilation inside the warehouse.

However, the ventilation device currently used in food storage warehouses has a simple structure and the size of the vents is fixed. Although the internal ventilation fan can be used to ventilate the interior of the warehouse, the temperature of the external environment varies with the seasons, so the amount of external air required to be exchanged varies. Therefore, higher requirements are placed on the adjustability of the ventilation device. However, conventional ventilation devices cannot meet the requirements of different ventilation volumes in food storage warehouses in different seasons. In view of this, we propose a ventilation device for food storage warehouses.

DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings and embodiments:

A ventilation device for a food storage warehouse, referring to FIGS. 1 to 3 , comprises a ventilation box 1 , a positioning plate 2 , a protection mechanism 3 , a ventilation fan 4 and an adjustment mechanism 5 ;

The positioning plate 2 is fixedly sleeved on the middle part of the outer side of the ventilation box 1, a protective mechanism 3 is provided at the front end of the ventilation box 1, a ventilation fan 4 is provided inside the ventilation box 1, the periphery of the ventilation fan 4 is tightly connected to the inner wall of the ventilation box 1, and an adjustment mechanism 5 is clamped at one end of the ventilation box 1 away from the protective mechanism 3. The utility model can effectively change the air intake of the ventilation box 1 by arranging the adjustment mechanism 5 at the end of the ventilation box 1, which is convenient for adjusting different air intakes in different seasons, avoiding the internal temperature of the food storage warehouse from being too low or too high, and improving the food storage effect inside the warehouse.

Specifically, the protection mechanism 3 includes a first guide rod 301, a nut 302, a second guide rod 303, a protection frame 304, a filter screen 305, and a hygroscopic screen 306. The first guide rod 301 is fixed at the upper left and lower right of the front end of the ventilation box 1. The front side of the first guide rod 301 is provided with threads on the outside, and the nut 302 is screwed on the outside of the threads. The second guide rod 303 is fixedly connected to the upper right and lower left of the front end of the ventilation box 1. Guide holes are provided at the four corners of the protection frame 304, and the protection frame 304 is mounted on the outside of the first guide rod 301 and the second guide rod 303 through the guide holes. The filter screen 305 and the hygroscopic screen 306 are matched and connected inside the protection frame 304, and the filter screen 305 and the hygroscopic screen 306 have the same specifications and sizes. In the utility model, a filter screen 305 is provided to filter external dust and impurities, thereby reducing the accumulation of dust inside the food storage warehouse and reducing the damage of the ventilation fan 4 caused by external foreign matter. The moisture-absorbing screen 306 can effectively absorb moisture and dry the external air, thereby reducing the humidity inside the food storage warehouse. The protective frame 304 can be removed by removing the nut 302, thereby facilitating the cleaning of the filter screen 305 and the moisture-absorbing screen 306 inside the protective frame 304.

Furthermore, the length of the first guide rod 301 is greater than that of the second guide rod 303, and threads are distributed on the periphery of the extra length of the first guide rod 301. In the utility model, the first guide rod 301 and the second guide rod 303 can quickly guide, insert and position the protective frame 304, thereby improving the assembly efficiency of the protective frame 304. The threads distributed on the periphery of the first guide rod 301 are used for threading with the nut 302, so that the nut 302 can limit the protective frame 304 and prevent the protective frame 304 from moving and falling during operation.

It is worth noting that the filter screen 305 and the moisture absorption screen 306 are parallelly distributed inside the protective frame 304, and there is a certain distance between the filter screen 305 and the moisture absorption screen 306. When the device is activated, the outside air passes through the filter screen 305 and the moisture absorption screen 306 in sequence, so as to process the outside air and reduce the impact of the outside air on the internal environment of the food storage warehouse.

It is worth noting that the adjustment mechanism 5 includes a small motor 501, a clamping rod 502, a wind shield 503 and a flexible strip 504. The small motor 501 is fitted on the upper end of the ventilation box 1. A slot is provided on the inner side of the end of the ventilation box 1 near the small motor 501. The clamping rod 502 is clamped inside the slot. The clamping rod 502 passes through and is fixed on the inner middle end of the wind shield 503. The upper end of the clamping rod 502 is connected to the output end of the small motor 501. Flexible strips 504 are bonded to both sides of the wind shield 503. In the utility model, a small motor 501 is used to drive the clamping rod 502 to rotate, thereby driving the wind shield 503 fixed on the outside of the clamping rod 502 to rotate, so as to adjust the angle of the wind shield 503 and further control the ventilation volume. The flexible strips 504 on both sides of the wind shield 503 can increase the sealing between the wind shield 503 and the inner wall of the ventilation box 1 without affecting the rotation adjustment of the wind shield 503. When the wind shield 503 is sealed with the inner wall of the ventilation box 1 through the flexible strips 504, the device can be in a completely disabled state to block the entry of outside air to meet more needs of warehouse food storage.

It is worth mentioning that the material of the flexible strip 504 is rubber.

Working principle: When the utility model is in use, first insert the ventilation box 1 into the reserved hole in the warehouse wall. At this time, the protective mechanism 3 is outdoors, the positioning plate 2 and the adjustment mechanism 5 are indoors, and the device is fixed to the surface of the warehouse wall as a whole through the threaded holes and threaded parts at the four corners of the positioning plate 2. When the warehouse is ventilated, the adjustment mechanism 5 is started according to the external environment temperature and the warehouse environment requirements, and the air intake of the ventilation box 1 is changed to avoid the internal temperature of the food storage warehouse being too low or too high. After the ventilation fan 4 is activated, the outside air passes through the filter screen 305 and the moisture absorption screen 306 in turn. The filter screen 305 filters the external dust and impurities, and the moisture absorption screen 306 absorbs moisture and dries the outside air. When the wind shield 503 is sealed with the inner wall of the ventilation box 1 through the flexible strip 504, the ventilation fan 4 is disabled at the same time, and the device can be in a completely disabled state to block the entry of outside air to adapt to more needs of warehouse food storage. When the filter screen 305 and the moisture absorption screen 306 need to be cleaned later, the protective frame 304 can be removed by removing the nut 302.

The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
