Description

Technical Field

[0001] The utility model relates to the technical field of silos, and specifically relates to a ventilation and heat dissipation type silo. Background Art

[0002] In the fields of agricultural production and industrial material handling, a silo is a vertical structure facility used to store solid granular materials such as grains, chemical raw materials, building materials, etc. Traditional silos are mainly used for temporary or long-term storage of materials to maintain the continuity of production and supply chains. Although existing silos are relatively effective in meeting basic storage needs, they have certain limitations in terms of material quality preservation and freshness preservation.

[0003] The existing silo designs generally ignore problems such as moisture absorption, caking, and high-temperature deterioration that materials may encounter during long-term storage. Without proper ventilation conditions, the temperature and humidity inside the silo may increase, which will lead to a decline in the quality of stored materials. Especially for biological materials such as grains, they are prone to phenomena such as mildew and rot, and in severe cases, it may even cause complete damage to the materials. In addition, the materials are prone to caking after being exposed to moisture, which not only affects the fluidity of the materials and the convenience of further processing, but may also cause damage to the internal structure of the silo. Although there are some silos with ventilation and heat dissipation functions on the market currently, they usually have problems of difficult maintenance and cleaning in design. Summary of the Utility Model

DETAILED DESCRIPTION

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

In the storage tower, an upper support disk 51, a middle support disk 52, and a lower support disk 53 for fixing the transmission sleeve are assembled. The transmission sleeve is arranged at the axis of the storage tower. The spiral conveyor blade 4 is rotatably installed in the transmission sleeve and keeps in contact with the inner wall of the transmission sleeve. The top and bottom of the transmission sleeve are respectively provided with a discharge through port 21 and a feed through port 22.

[0024] The annular air supply groove 3 is fixedly installed at the bottom of the lower support disk 53 and is concentrically arranged with the storage tower. The annular air supply groove 3 is evenly assembled with air supply nozzles 31 arranged vertically downward. A wind collecting hood 13 is provided at the top of the storage tower. A discharge ventilation port 131 is opened on the wind collecting hood 13. A wind supply pipe 14 communicating with the annular air supply groove 3 is fixedly connected to the bottom of the storage tower.

[0025] When storing materials and grains in the storage tower, they are injected into the storage tower from the feeding port 11 at the top of the storage tower and gather at the bottom of the storage tower under the action of gravity. During long-term storage, it is necessary to turn over and ventilate the materials and grains therein to avoid phenomena such as moisture agglomeration and temperature accumulation and deterioration of the materials and grains, so as to ensure the long-term stable storage of the materials and grains in the storage tower. At the discharging port 12 at the bottom of the storage tower, equipment such as a switch valve and a discharging device are assembled for discharging the materials or grains stored in the storage tower.

[0026] When driving the spiral conveyor blade 4 to operate, the spiral conveyor blade 4 can convey the materials or grains entering from the feed through port 22 at the bottom of the transmission sleeve upward and finally output from the discharge through port 21 at the top of the transmission sleeve, realizing the turning operation of the materials and grains inside the storage tower to ensure that the materials or grains in the storage tower are in a flowing state and avoid moisture agglomeration.

[0027] The annular air supply groove 3 and the spiral conveyor blade 4 cooperate to supply dry cold air from the air supply pipe 14 at the bottom of the storage tower to the annular air supply groove 3 during the material turning operation, and finally evenly transport it to the bottom of the storage tower through the air supply nozzles 31. During the process of the dry cold air flowing towards the top of the storage tower, it can cool the materials and grains therein, and at the same time can take away the water vapor contained therein, and finally gather in the air collecting hood 13 at the top of the storage tower and be discharged outward through the exhaust vent 131. During the process of the spiral conveyor blade 4 driving the materials and grains to flow, it can make the materials and grains in various parts of the storage tower fully contact with the dry cold air, so as to improve the effect of heat dissipation, cooling and drying treatment of the materials and grains.
