Description

Technical Field

[0001] This utility model relates to the field of sand and gravel aggregate storage technology, and in particular to a steel silo for sand and gravel aggregate. Background Technology

[0002] Steel silos for sand and gravel aggregates are devices used for storing and managing building materials such as sand and gravel aggregates. They are commonly used in construction sites, sand and gravel plants, and concrete production. The main function of steel silos is to store large quantities of aggregates such as sand, gravel, and crushed stone, ensuring the supply of raw materials and helping to improve production efficiency, reduce waste, and enhance the convenience of management and transportation.

[0003] In the prior art, Chinese patent application number 202222876712.2 discloses a sand and gravel aggregate storage silo, belonging to the field of aggregate storage technology. It includes a storage tank with blowers welded to both ends. Each end of the tank has an air inlet connected to one of the blowers. An annular inclined plate is welded to the bottom of the tank's inner cavity. Air supply pipes are welded to both sides of the top wall of the inclined plate, and each air supply pipe is connected to one of the air inlets. Air outlets are located on opposite sides of the two air supply pipes, and wire mesh is welded to the openings of both outlets. An exhaust pipe is welded to the center of the tank's top wall, and an exhaust fan is installed inside the exhaust pipe. The exhaust fan directs the airflow vertically upwards. Feeding pipes are welded to both sides of the tank's top wall. This sand and gravel aggregate storage silo ensures constant air circulation within the tank, improving the environmental conditions and preventing the sand and gravel aggregate from becoming damp during long-term storage.

[0004] However, the above-mentioned technical solutions have exhaust pipes and exhaust fans located on the top of the storage tank and are in an open state. Since the storage silos used to store sand and gravel aggregates are large in volume and are generally located outdoors, rainwater will enter the interior of the storage tank through the exhaust pipes in rainy weather, causing the sand and gravel aggregates to become damp and affecting subsequent use. At the same time, it will also cause the exhaust fans to be damaged by water. Therefore, this application proposes a steel plate silo for sand and gravel aggregates to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing technologies where the exhaust pipe and exhaust fan are located on the top of the storage tank and are in an open state.

[0042] The working principle of this utility model is as follows: In use, firstly, connect the discharge valve 6, blower 7, electric push rod 12, first motor 14, and second motor 19 to an external power source. Then, by starting the blower 7, outside air is continuously supplied into the silo 1. The air is then exhausted through the exhaust fan inside the exhaust pipe 8 at the top of the silo 1, ensuring constant air circulation within the silo 1. This improves the environmental conditions of the silo 1, preventing the sand and gravel aggregates from becoming damp during long-term storage. Furthermore, the rain canopy 10 protects the top of the exhaust pipe 8, preventing water from entering the silo 1 during rain or snow, ensuring the sand and gravel aggregates remain dry for subsequent use. Activating the electric push rod 12 allows for height adjustment of the canopy 10, facilitating the contact between the cleaning components and the protective filter 9 for cleaning. It also enables convenient disassembly and maintenance of the protective filter 9. Furthermore, activating the first motor 14 rotates the lead screw 15, which, through the threaded connection between the lead screw 15 and the nut 16, moves the U-shaped frame 17 and the cleaning roller 18 laterally. Activating the second motor 19 rotates the cleaning roller 18, which cleans the dust from the protective filter 9, preventing clogging and ensuring its ventilation.
