Problems solved by technology

However, the warehouse with a flat bottom structure cannot be unloaded by gravity, so only a spiral clearing machine can be used.
This kind of machinery is not only expensive, but it is not only easy to be corroded and damaged when buried under the material when the warehouse is full, but also requires manual supervision during the discharge process, which is very inconvenient

Embodiment 1

[0031] The vibrating unloading silo with a central discharge hopper is composed of: a silo body 1, a silo bottom 3 with a central gravity hopper 2 and a silo cover 4. A set of sloping installations around the central gravity hopper 2 The unloading tray 5, the disc 6 of the unloading tray 5 can be made into a fan-shaped, strip-shaped or polygonal shape, and the unloading tray is connected to a vibration source 7. The feeding tray is divided into 4-50 pieces according to the diameter of the silo body, mainly divided into sectors, which can be divided into several rings first, and then divided along the diameter.

[0032] The vibration source is a vibration motor, or an impact head driven by a pneumatic pump or a hydraulic pump, or an eccentric cam driven by a motor can be used to generate vibration.

Embodiment 2

[0034] In the vibrating unloading silo with a central discharge hopper described in Example 1, a reset spring 8 is provided at the lower part of the lowering tray. The reset spring can be a leaf spring used in a car, or a tension spring or a compression spring. , The main function is to lift the disc to a certain distance from the bottom of the warehouse, which can reduce wear and facilitate vibration work.

Embodiment 3

[0036] In the above-mentioned vibration unloading silo with a central discharge hopper, the vibration source is a vibration motor or a cam structure connected to the motor, which generates bump vibration through the rotation of the cam or through the impact of a pneumatic piston or a hydraulic pulse piston. The vibration source of the environment where the warehouse is located can also be provided in other ways. The vibration motor is the best. It is confirmed by experiments that when the vibration source is installed on the side of the disc off the center of the gravity bucket , The effect is better, the following materials will speed up the flow rate and increase the flow during the process of collapse and self-flow. Generally, the vibration source can be installed on the downward side of the disc, which is convenient for maintenance and can avoid moisture erosion.

Abstract

The invention relates to a vibratory discharge silo with a central discharge hopper and a discharge method. A conical bottom structure mostly adopted by an existing silo in discharge is large in silo height occupancy, low in volume rate and high in center of gravity. The vibratory discharge silo with the central discharge hopper structurally comprises a silo body (1), a silo bottom (3), a silo cover (4) and a group of discharge disks (5), wherein the silo bottom (3) is provided with the central automatic discharge hopper (2), and the discharge disks (5) are centripetally and obliquely mounted around the central automatic discharge hopper (2), comprise sector-shaped, strip-shaped or polygonal disk pieces (6) and are connected with vibration sources (7). The silo can be used for storing materials such as grains, coal and the like.

Description

Technical field: [0001] The invention relates to a silo with a central discharging hopper and a vibrating discharging device, and a vibration unloading method for the silo. Background technique [0002] Bulk materials such as grains, minerals, etc., have a large circulation volume and require a high degree of mechanization. Material discharge has always been a worldwide problem. For small silos, such as silos with a straight length of less than 10m, the bottom can be made into a cone. It can completely flow out of the warehouse to meet the requirements of mechanized production. However, due to the large diameter of the large silo, if the bottom is made into a cone, the space is very high, and the cost is also high. Take the granary as an example. At present, the common practice of large grain silos is to make the foundation into a flat bottom with multiple outlets. After the automatic flow of the grain is completed, the remaining about one third of the grain is discharged by the...
