Description

Technical Field

[0001] The utility model relates to the technical field of silos, in particular to a silo capable of vacuum-sucking accumulated materials. Background Art

[0002] A silo is a large storage facility for bulk materials. It is usually cylindrical or cylindrical, with a conical bottom and one or more openings or feed ports on the top. Silos are usually used in industries, agriculture, ports, etc. to store and protect materials to ensure their quality and supply. Silos are usually built with strong materials such as steel and concrete. They have good structural stability and pressure resistance and can withstand the weight of materials and the impact of the external environment. When materials are stored for a long time or the silos currently on the market are in use, it is easy for some powder materials to adhere to the bottom of the silo and agglomerate after a long period of storage or moisture. As the agglomerated materials increase, it will affect the normal discharge of the silo. Therefore, we propose a silo that can vacuum-absorb accumulated materials, which can timely absorb the agglomerated accumulated materials. Utility Model Content

[0023] During the specific implementation, the gas inside the silo body 1 is extracted through the connecting pipe 10 by starting the vacuum pump 9 and cooperating with the suction pipe 8, so that the pressure inside the silo body 1 is lower than the atmospheric pressure. Under the action of the negative pressure environment, the agglomerated materials attached to the edge of the bottom plate of the silo body 1 are loosened and begin to fall off, and then the second gear 14 connected to the output end is driven to rotate synchronously by starting the motor 15. Since the second gear 14 and the first gear 13 are meshed, the suction pipe 8 can be driven to rotate synchronously through the first gear 13 as the second gear 14 rotates. The upper part of the rotating suction pipe 8 moves stably along the inside of the mounting seat 11 through the guide block 12, and the bottom end of the rotating suction pipe 8 is used to suck different positions below the silo body 1. The suction pipe 8 is rotated by the mutual cooperation of the motor 15, the second gear 14 and the first gear 13. The rotating suction pipe 8 and the vacuum pump 9 cooperate to suck the agglomerated materials at different positions at the bottom, so that the silo can vacuum-suction the accumulated materials.

[0024] See also Figure 1 and Figure 4A fixed column 17 is provided in the middle of the top of the sealing cover 24, and a threaded rod 18 is connected to the inside of the fixed column 17 through a bearing seat, and a moving column 19 is inserted in the middle of the fixed column 17; a protective cover 20 is connected to the upper end of the moving column 19, and a limiting seat 21 is connected to the upper sides of the moving column 19, and the end of the limiting seat 21 away from the moving column 19 is inserted in the inside of the fixed column 17; a bevel gear set 22 is sleeved and installed on the lower outer side of the threaded rod 18, a motor 23 is installed on the outer side of the fixed column 17, and the output end of the motor 23 passes through the fixed column 17 and is connected to the bevel gear set 22, the limiting seat 21 is symmetrically distributed about the center line of the moving column 19, and the limiting seat 21 is slidably connected to the fixed column 17, and the threaded rod 18 and the moving column 19 are threadedly connected.

[0025] During specific implementation, the distance between the protective cover 20 and the sealing cover 24 is the largest in the initial state. After the inside of the silo body 1 is fed with materials from the feeding port 2, the bevel gear set 22 connected to the output end is driven to rotate synchronously by starting the motor 23, and the threaded rod 18 rotates synchronously with the rotation of the bevel gear set 22. Since the threaded rod 18 and the movable column 19 are threadedly connected, the outgoing movable column 19 can move downward along the fixed column 17 with the rotation of the threaded rod 18, and the movable column 19 that moves downward with the protective cover 20 moves downward synchronously. The movable column 19 that moves up and down drives the connected limit seat 21 to move steadily downward along the outer side of the fixed column 17 until the movable column 19 is moved down to the extreme position. At this time, the protective cover 20 on the movable column 19 is attached to the upper edge of the sealing cover 24. By arranging a protective cover 20 that can move up and down above the sealing cover 24, the upper part of the sealing cover 24 can be blocked, so that the silo has a protective structure.

[0026] To sum up, when using the silo that can vacuum-suction accumulated materials, first move the silo body 1 and place it in the designated use area, then add the material to be stored into the silo body 1 through the feeding port 2. When the material needs to be taken out, open the valve on the discharge port 3 to discharge the material from the discharge port 3. When the accumulated material is adhered to the inner wall at the bottom of the silo body 1 by agglomeration, start the vacuum pump 9 and the suction pipe 8 to cooperate with each other to extract the gas inside the silo body 1 through the connecting pipe 10, so that the pressure inside the silo body 1 is lower than the atmospheric pressure. Under the action of the negative pressure environment, the agglomerated material adhered to the edge of the bottom plate of the silo body 1 is loosened and begins to fall off.
