Description

Technical Field

[0001] The utility model relates to the technical field of material discharge equipment, in particular to a coal discharge structure of a pulverized coal bin. Background Art

[0002] In industrial production, pulverized coal silos are important equipment for storing pulverized coal. Traditional pulverized coal silo coal discharge structures often have some problems.

[0003] In terms of storage, pulverized coal easily accumulates and clogs the silo, affecting the normal discharge of pulverized coal. In addition, the existing storage structure lacks effective anti-clogging measures, resulting in frequent shutdowns for cleaning during production, reducing production efficiency.

[0004] In the discharge process, traditional discharge devices lack effective dust suppression measures. Coal powder will generate a large amount of dust during the discharge process, which not only pollutes the environment but also harms the health of operators.

[0005] In addition, the existing structure is not flexible and efficient enough in controlling the opening and closing of the baffles, and cannot meet the demand for precise discharge. Therefore, a new coal pulverized coal bunker discharge structure is needed to solve these problems. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a coal discharge structure for a pulverized coal bin with smooth material discharge, flexible controllable material discharge rate and effective dust suppression.

[0007] In order to achieve the above-mentioned object, the utility model provides a coal discharge structure of a pulverized coal bin, comprising a support frame, on which a storage device and a discharge device are respectively installed from top to bottom;

[0008] A material storage device, comprising a material storage bin, wherein a middle bin protrudes from the middle of both sides of the material storage bin, and an anti-blocking mechanism is installed through the middle bin on both sides;

[0009] A mounting plate is protruded around the outer periphery of the lower opening of the storage bin, and a fixed plate is provided at the lower end of the mounting plate and is placed on the front and rear sides of the lower opening of the storage bin. Baffles are movably installed between the front and rear fixed plates and are placed on both sides of the lower opening of the storage bin. A bracket is also provided at the upper end of the mounting plate, and a pneumatic mechanism for controlling the opening and closing of the baffles on both sides is installed through the bracket;

[0010] The discharging device comprises a lower hopper, the upper end opening of the lower hopper is placed at the lower end of the storage bin, and a dust suppression cloth strip is installed around the outer side of the lower end opening of the lower hopper.

[0011] Preferably, the storage bin is a rectangular cavity structure that is hollow inside and open at both ends. The middle bin is a shell protruding from both sides of the storage bin. The outer side of the middle bin is an arc-shaped structure. Both the front and rear ends of the middle bin are opened, and an anti-blocking mechanism is installed on both sides of the middle bin.

[0012] Preferably, the anti-blocking mechanism includes a threaded roller, which is mounted in the middle warehouse. The front and rear ends of the threaded roller extend to the outside of the middle warehouse through the front and rear openings of the middle warehouse. A transmission belt is provided between the front and rear extended ends of the threaded rollers in the middle warehouses on both sides, and a motor is coaxially connected to one extended end of a threaded roller.

[0013] Preferably, mounting holes are provided at both left and right ends of the fixed plate, and a baffle is movably installed between the mounting holes of the front and rear fixed plates. The upper end of the baffle has a fixed shaft, and the baffle is mounted between the mounting holes of the front and rear fixed plates through the fixed shaft. The baffle can be flipped and rotated with the fixed shaft as the axis.

[0014] Preferably, the pneumatic mechanism includes a cylinder, which is placed in the middle of the bracket. A connecting piece is installed at the lower end of the cylinder. Both ends of the connecting piece are respectively connected to the side edges of the baffles at both ends. The opening and closing of the baffle is controlled by the extension and contraction of the shaft at the lower end of the cylinder.

[0015] Preferably, there are multiple dust suppression strips, which are circumferentially suspended outside the lower opening of the discharge hopper. The beneficial effects of the utility model are as follows: 1. By adding a middle bin on both sides of the storage bin and installing a threaded roller inside the middle bin, the threaded roller is driven by a motor to rotate, thereby loosening the coal powder in the storage bin to facilitate discharge and prevent the accumulation of powdered material from clogging the inside of the bin.

[0016] 2. By adding a baffle that can be opened and closed by a cylinder at the lower end of the storage bin, the opening and closing degree of the baffles on both sides of the lower end opening of the storage bin can be controlled according to the demand for coal powder to select the size of the discharge rate.

[0017] 3. By hanging dust suppression strips around the outer perimeter of the lower opening of the lower hopper, pulverized coal is discharged from the lower opening. The falling process creates airflow disturbances, which can easily lift up pulverized coal and form dust. The dust suppression strips block and absorb this raised pulverized coal, suppressing dust and reducing pollution to the surrounding environment. This prevents pulverized coal from spreading in the air, affecting air quality and endangering the health of workers. Furthermore, the strips can slow the pulverized coal's descent to a certain extent, making it more stable and reducing the impact of its rapid fall. This helps protect the receiving equipment or transport device below, extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Furthermore, the storage bin 2 is a rectangular cavity structure that is hollow inside and open at both ends. The middle bin 201 is a shell protruding from both sides of the storage bin 2. The outer side of the middle bin 201 is an arc-shaped structure. Both the front and rear ends of the middle bin 201 are opened, and an anti-blocking mechanism is installed on both sides of the middle bin 201.

[0030] Furthermore, the anti-blocking mechanism includes a threaded roller 4, which is mounted in the middle warehouse 201.
