Description

Technical Field

[0001] The invention belongs to the technical field of conveying equipment, and in particular relates to a double-door sealed bin system. Background Art

[0002] With the development of industry, the amount of hazardous waste discharged during industrial production processes is increasing. Some waste materials with higher risks of combustion and explosion are prone to fire or even explosion due to pressure shock during the crushing, mixing, and pumping stages of pre-treatment, causing damage to equipment and personnel. In order to reduce the risk of explosion and fire, some experienced and qualified hazardous waste pre-treatment equipment will reduce the oxygen concentration in these areas by regularly injecting inert gases (such as nitrogen, etc.) into the feeding area, crushing bin, mixer, etc. during the pre-treatment of some highly explosive waste materials, thereby reducing the risk of combustion and explosion. However, the processing of equipment such as crushing bins and mixers is continuous, but the feeding is not continuous. If the crushing bin is directly opened during feeding, the inert gas will escape, which will not only cause exhaust gas leakage, but also increase the cost of inert gas.

[0003] In order to solve the above problems, a double-door sealed bin is provided at the feed port of the crushing bin, and the two separately controlled doors of the double-door sealed bin are used to control the materials from entering the crushing bin, thereby avoiding damaging the sealed environment filled with inert gas in the crushing bin. In order to transport materials, a horizontal transport structure and a flip structure are generally provided in the double-door sealed bin. The horizontal transport structure is used to transport the materials to the designated location, and the flip structure is used to tilt the pallet or ton barrel placed on the horizontal transport structure, thereby dumping the materials into the crushing bin. However, due to limited space, some materials directly contact the horizontal transport structure and the flip structure, thereby damaging the horizontal transport structure and the flip structure; and the horizontal transport structure and the flip structure are both located in the sealed box, which further leads to maintenance difficulties.

[0029] A conveying assembly, the conveying assembly is located in the box body 1, and includes a turning frame and a conveying roller 6, the first end of the turning frame is rotatably installed in the first opening and closing door 3, and the second end is located at the second opening and closing door 2; the conveying roller 6 is installed on the turning frame, and the number of the conveying rollers is multiple, and the multiple conveying rollers 6 are arranged along the length direction of the turning frame;

[0030] A control component is located outside the box body 1 , and includes a flip actuator 7 and a drive mechanism 8 . The flip actuator 7 is connected to the flip frame, and the drive mechanism 8 is connected to the conveying roller 6 .

[0031] Furthermore, the flip frame includes a flip shaft 4 and a beam 5, the flip shaft 4 is installed in the box body 1, and the end thereof extends out of the box body 1 and is connected to the flip actuator 7; there are two beams 5, and the ends of the two beams 5 are fixedly mounted on the flip shaft 4; along the length direction, a plurality of mounting holes are provided on the beam 5, and the mounting holes are suitable for installing the conveying roller 6.

[0032] Specifically, the beam frame 5 is composed of two bar-shaped structures with a plurality of semicircular grooves on the side. When assembled, the corresponding two semicircular grooves form a circular hole, wherein the circular hole at the end is also provided with a keyway for fitting and fixing on the flip shaft 4, and the circular holes at other positions are used for passing the conveying roller 6. The two beam frames 5 are parallel to each other, so that the conveying roller 6 is located on the same plane and remains stable.

[0033] Furthermore, a first gear ring is provided at the end of the conveying roller 6, and a second gear ring is provided on the output shaft of the driving mechanism 8, and the first gear ring is meshed with the second gear ring.

[0034] Specifically, the conveying roller 6 is meshed with the gear ring on the output shaft of the driving mechanism 8 through the first gear ring, so that the conveying roller 6 and the output shaft of the driving mechanism 8 are non-fixed connection structures, and the meshing position with the first gear ring is located at the bottom of the first gear ring, which can not only realize the connection between the driving mechanism 8 and the conveying roller 6, but also does not affect the flipping of the flip frame, so that the conveying roller 6 is connected to the driving mechanism when the flip frame is in a horizontal state, and disconnected from the driving mechanism when the end of the flip frame is tilted. Further, in the above structure, the number of conveying rollers 6 provided with the first gear ring can be one, in which case the conveying roller 6 provided with the first gear ring is located in the middle of the flip frame, so that it can drive pallets or ton barrels at any position. The number of conveying rollers provided with the first gear ring can also be multiple, in which case the driving mechanism is adjusted accordingly, so that it also includes a gear set in which a plurality of gears are arranged horizontally and meshed for transmission, in which case the second gear ring of the output shaft of the driving mechanism meshes with the gear set, and a plurality of gears with the same rotation direction in the gear set cooperate with the first gear ring.

When it is needed, open the second opening and closing door 2, place the pallet or ton barrel on the conveying roller 6, and inject the material to be conveyed into the pallet or ton barrel. Then, the conveying roller 6 is driven by the driving mechanism to rotate, the pallet or ton barrel is conveyed to the middle of the box body 1, and the second opening and closing door 2 is closed. At this time, the box body 1 is in a sealed state. Start the gas injection device and inject inert gas into the box body 1 through the air inlet, and exhaust it synchronously through the air outlet until the content and pressure of the inert gas in the box body 1 reach the preset value. Then open the first opening and closing door 3, and start the flip actuator 7, so that one end of the flip frame is tilted, thereby driving the pallet or ton barrel to tilt, so that the material in the pallet or ton barrel flows into the crushing box. After the material is conveyed, the overturning actuator 7 is started to drive the overturning frame to rotate in the opposite direction, that is, the free end is reset, and then the driving mechanism is started to make the conveying roller 6 rotate in the opposite direction, thereby conveying the pallet or ton barrel to the second opening and closing door 2.
