[0043] How it works
[0044] The working process of the present invention is divided into 1. feeding, 2. distributing, 3. stirring and preventing blocking, 4. discharging and loading;
[0045] 1. Feeding: Use external feeding device (belt, scraper) to feed coal slime into the round silo through the feeding port 1-7 on the top of the silo. The operator shall adjust the running status of the feeding equipment in time according to the material level display and pay attention to the coal slime situation in the silo.
[0046] 2. Material distribution: This process is completed by the material distribution rack and the driving mechanism. The material distribution hydraulic cylinder (powered by the hydraulic station) pushes the material distribution rack to make the coal slurry circulate in the silo and evenly distribute it in the silo, so as to minimize the influence of the coal slurry accumulation angle on the effective volume of the silo. At the same time, the material distribution rack continuously pushes the coal slurry to effectively prevent the coal slurry from arching at the outlet. The material distribution slide is elliptical and is driven by the material distribution rack driving mechanism. When the material distribution rack driving mechanism reciprocates to the two end points of the stroke, the inductive proximity switch 8-9 sends a signal, and the electronic control system controls the solenoid valve reversing 5-8, so that the material distribution rack 8 moves in the opposite direction.
[0047] 3. Stirring and blocking prevention: To prevent the coal slime from hardening and arching and being unable to be discharged, the stirring shafts 1-8 must be turned on. The stirring shafts 1-8 are driven by the stirring motor and the reducer, and stir at a very low speed to prevent the coal slime from hardening and arching. The stirring operation is irregular. The operator starts the stirring operation according to the moisture content of the coal slime, the storage time, and the observation of the material level and sampling and testing.
[0048] 4. Unloading and loading: The transport vehicle drives into the car channel, opens the flat gate to the left and right, and the material distribution slide 8 cooperates to unload the coal slime and load it. The coal slime flat gate adopts a plate valve structure, powered by a hydraulic cylinder, and is installed below the material distribution slide 8 and at the bottom of the warehouse. The gate is composed of a hydraulic cylinder, a gate plate, and upper and lower gate plates. The hydraulic cylinder pushes the gate plate to move to achieve the blocking and unblocking of the coal slime conveying channel. The hydraulic cylinder uses the pressure oil of the hydraulic station to work. When unloading is required, the hydraulic cylinder drives the flat gate to move, and the gate valve is moved by operating the manual reversing valve on the hydraulic station until the use requirements are met. The flat gate and material distribution slide are manually operated through the reversing valve of the hydraulic station, and the stirring shafts 1-8 are manually operated through the electric control box.
