The silo clearing machine is used to clean the slime deposited in the silo of coal mine, and it is suitable for the digging, pumping, and other processes of the silo slime.Structure of the clearance machineThe clearance machine is composed of a feeding device, a digging device, a pumping device, a walking device, a control device, an electrical system, a hydraulic system, etc. The working process is that the moving device drives the body forward, the material is strongly stirred by the aggregate screw and collected to the middle part; at the same time, the coal slime at the bottom of the silo and the fine coal machine at the top of the silo are mixed into uniform coal mud, and the coal slurry is transported to the hopper of the pumping device through the feeding screw to provide stable liquid, and the mining device can dig and clean the sediment slime layer. It can swing to the right and left by 45°, which can effectively improve the width of slime aggregate and feeding efficiency. Finally, it can be pumped at high pressure through the pumping device to achieve long-distance transportation.
Introduction to clearance machine
The silo clearing machine is used to clean the slime deposited in the silo of coal mine, and it is suitable for the digging, pumping, and other processes of the silo slime.
Structure of the clearance machine
The clearance machine is composed of a feeding device, a digging device, a pumping device, a walking device, a control device, an electrical system, a hydraulic system, etc.
Working principles of the clearance machine
The working process is that the moving device drives the body forward, the material is strongly stirred by the aggregate screw and collected to the middle part; at the same time, the coal slime at the bottom of the silo and the fine coal machine at the top of the silo are mixed into uniform coal mud, and the coal slurry is transported to the hopper of the pumping device through the feeding screw to provide stable liquid, and the mining device can dig and clean the sediment slime layer. It can swing to the right and left by 45°, which can effectively improve the width of slime aggregate and feeding efficiency. Finally, it can be pumped at high pressure through the pumping device to achieve long-distance transportation.
Characteristics of the clearance machine
1. The addition of the digging arm working device can clean up the residual material that cannot be collected by the spiral, effectively improve the width of the slime aggregate and the charging efficiency, and avoid the sudden collapse of the silting layer and the surge to protect the safety of the staff.
2. Aiming at the defects of slurry pump transportation, spiral aggregate is used to enter the mining concrete pump transportation system after loading, which has the advantages of large pumping capacity, high efficiency, high pumping pressure, and long conveying distance.
3. load-sensitive control valve so that the control action is coordinated, the system is stable and reliable, has low power consumption, and has high efficiency.
4. The whole machine is modular, can be split, and is easy to repair and maintain.
5. The structural parts of the whole machine are all Q345B, and the strength of the whole machine is ensured by three-dimensional finite element-aided design and network stress analysis.
