Technical Field
[0001] This utility model belongs to the technical field of material separation equipment, and in particular relates to an intelligent and environmentally friendly material separation and treatment system suitable for fully weathered materials. Background Technology
[0002] Currently, the disposal of fully weathered surface material is a common problem faced by most mines during the construction of green mines. If waste stockpiling is used, the selection of a suitable stockpile site becomes an unavoidable and unsolvable issue. Therefore, most mines choose comprehensive utilization of fully weathered material, processing the mud and fine particles in the raw material to obtain washed sand, turning waste into treasure and generating certain economic benefits. However, in the actual comprehensive utilization production process, the fully weathered surface material and topsoil stripping processes are not continuous, leading to frequent start-ups and shutdowns of crushing equipment, shortening equipment lifespan, increasing energy consumption, and raising operating costs. The mud or other fine particle content in the raw materials varies in different green mine projects, and the processing of small-diameter materials cannot be flexibly adjusted according to the material supply. Currently, the conventional practice in green mine projects is to set up a pre-screening workshop after the primary crushing process to separate mud and small materials. However, this approach leads to an increased crusher damage rate in the primary crushing stage, reduced crushing efficiency and capacity, increased likelihood of feeder blockage, increased energy consumption, and increased equipment and civil engineering investment costs in the pre-screening workshop.
[0003] This invention designs an intelligent and environmentally friendly material separation and processing system suitable for fully weathered materials to solve the above problems. Utility Model Content

[0009] The processing area is also equipped with a bar feeder, a material distribution device, and a crusher. The bar feeder is installed below the discharge port at the bottom of the large-diameter silo area. The material distribution device is installed below the bar feeder. The discharge end of the material distribution device faces two conveyor belts respectively. The discharge end of the bar feeder is close to the feed end of the crusher. The discharge end of the crusher faces one of the conveyor belts.
[0010] It also includes PLC equipment, and the spacing of the bars inside the grate screen, the bar valve, the vibrating feeder, the bar feeder, the material distribution device, the crusher, and the belt conveyor are all controlled by the PLC equipment.

[0032] A first level gauge 25 is installed in the small-diameter silo area 22, and a second level gauge 26 is installed in the large-diameter silo area 21. An inspection door 23 is opened on the side wall of the small-diameter silo area 22. The first level gauge 25 detects the amount of material in the small-diameter silo area 22, and the second level gauge 26 detects the amount of material in the large-diameter silo area 21. The first level gauge 25 and the second level gauge 26 can send signals to the PLC equipment.
[0033] Two first discharge ports are provided at the bottom of the small particle size silo area 22, and two bar valves 31 are respectively provided at the first discharge ports. A second discharge port is provided at the lower end of the large particle size silo area 21, and a chute 39 is installed at the second discharge port. The lower end of the chute 39 extends into the bar feeder 34.
[0034] The discharge status of the small particle size hopper area 22 is controlled by the bar valve 31, and the discharge status of the large particle size hopper area 21 is controlled by the bar feeder 34. When the bar feeder 34 is not vibrating, the large particle size hopper area 21 will not discharge.
[0035] Both vibrating feeders 32 have a first discharge channel 36 installed at their discharge ends, and the two first discharge channels 36 face the two conveyor belts 38 respectively. The crusher 33 has a second discharge channel 40 installed at its discharge end, and the second discharge channel 40 faces one of the conveyor belts 38.

The first level gauge 25 and the second level gauge 26 can send signals to the PLC equipment.
[0038] Work steps:
[0039] S1: Dump truck 11 enters unloading area 1 and dumps the loaded material into receiving bin area 2. At the same time, dry fogger 12 starts dust suppression.
[0040] S2: The grate screen 24 in the receiving bin area 2 classifies materials of different particle sizes. Small particle size materials pass through the grate screen 24 and are stored in the small particle size bin area 22, while large particle size materials slide down along the upper end face of the grate screen 24 and are stored in the large particle size bin area 21.
[0041] S3: Based on the feedback signal from the first level gauge 25, after the material in the small particle size hopper area 22 reaches the predetermined amount, the PLC equipment opens the bar valve 31 and controls the operation of the bar valve 31, the vibrating feeder 32, and the corresponding conveyor belt 38.
[0042] According to the feedback signal from the second level gauge 26, after the amount of material in the large particle size silo area 21 reaches the predetermined amount, the PLC equipment controls the bar feeder 34, the material distribution device 35, the crusher 33 and the corresponding conveyor belt 38 to run.
[0043] S4: The material discharged from the small-diameter hopper area 22 is conveyed to the belt conveyor 38 by the bar valve 31 and the vibrating feeder 32. The material discharged from the large-diameter hopper area 21 falls onto the bar feeder 34. The larger-diameter material is conveyed to the crusher 33 by the bar feeder 34, crushed by the crusher 33, and then conveyed to the belt conveyor 38. The small-diameter material mixed in passes through the bar feeder 34 and falls onto the distribution device 35, and is then conveyed to the belt conveyor 38 by the distribution device 35.
[0044] Depending on the value of the material, if there is a large amount of sand or other reusable raw materials with high utilization value, the conveyor belt 38 will transport them to the subsequent production process. If the material has low utilization value or a high proportion of mud, the conveyor belt 38 will transport it to the subsequent waste treatment process.
[0045] With only the small-diameter hopper area 22 open, both conveyor belts 38 can be used to transport the material discharged from the small-diameter hopper area 22.
[0046] With only the large-diameter hopper 21 open, one conveyor belt 38 is used to transport the small-diameter material screened out by the bar feeder 34, and the other conveyor belt 38 is used to transport the material crushed by the crusher 33.
[0047] With both the small-diameter silo area 22 and the large-diameter silo 21 open, one conveyor belt 38 is used to transport the material discharged from the small-diameter silo area 22 and the material screened out by the bar feeder 34, while the other conveyor belt 38 is used to transport the material crushed by the crusher 33.
