Description

Technical Field

[0001] The utility model relates to the technical field of ore impurity removal, in particular to an impurity removal device for phosphate rock mining equipment. Background Technique

[0002] Phosphate rock is an ore containing phosphorus, which is mostly produced in sedimentary rocks, and also in metamorphic rocks and igneous rocks. Phosphorus is an important chemical raw material and also a necessary element for the growth of crops. Industrial phosphorus must be extracted from phosphate rock in large quantities. After the phosphate rock is mined by mining equipment, since some sediment, dust and impurities will adhere to the outside of the mined phosphate rock, an impurity removal device is needed to wash and clean the ore material mined by the mining equipment to remove impurities.

[0003] According to a calcium carbonate ore water washing and impurity removal device disclosed in Patent No. CN202022374297.1, the stirring rod on the stirring paddle flips the calcium carbonate ore while washing the calcium carbonate ore with water, realizing the full cleaning of the calcium carbonate ore. Water guide grooves are fixedly connected to both sides of the bottom plate, so that the water flowing out of the water washing tank can flow back to a predetermined place, improving the working efficiency of the water washing and impurity removal of calcium carbonate ore.

[0004] When the above-mentioned impurity removal device washes and removes impurities from the ore, by adopting the method of flipping the ore inside the device to assist in fully washing and removing impurities from the outside of the ore, but in actual operation, due to the different sizes and volumes of the ore, when some larger ore blocks are washed with water when introduced into the device, they are likely to get stuck in the stirring paddle and the stirring rod, making it unable to rotate normally, so that the electric drive device is burned out. If the large ore blocks are lifted by the stirring rod, they are also likely to hit the inner wall of the device, resulting in abnormal vibration of the device. When washing with water, the cleaning water and the ore are basically in a relatively static state, and the cleaning effect on the sediment and the like on the outside of the ore is poor and the efficiency is low. There are deficiencies, and it is not convenient to efficiently remove impurities from the outside of the phosphate rock.

[0005] Now, a new type of impurity removal device for phosphate rock mining equipment is proposed to solve the above deficiencies. Content of the Utility Model

Embodiment 3

[0034] An installation plate 6 is provided at the top end of the fixed barrel 2, and support rods 5 are respectively welded and fixed at both ends of the bottom sides of the installation plate 6, and the bottom ends of the support rods 5 are welded and fixed to the top end of the chassis 1.

The output end at the bottom of the electric push rod 7 penetrates through the inside of the top end of the installation plate 6 and is installed and fixed to the top end of the cover body 8. The electric push rods 7 and the support rods 5 are symmetrically arranged with respect to the vertical center line of the installation plate 6;

[0035] Specifically, as Figure 1 and Figure 2 shown, the ore material is introduced into the screen 10 inside the cylindrical frame 9, and after the fixed barrel 2 is filled with water, then the electric push rod 7 can be controlled to drive the cover body 8 to move downward and stick to the top end of the fixed barrel 2 to assist in closing the inside of the fixed barrel 2, which can prevent the ore material from flying out during the rotation cleaning inside the device and assist in limiting the position during the washing and decontamination of the phosphate rock.

[0037] Working principle: When the utility model is in use, when the impurity removal device removes external dust and other impurities from the mined phosphate rock, while introducing the ore material from the top of the cylindrical frame 9 into the inside of the screen 10, water can be injected into the inside of the fixed barrel 2. After introducing the ore material into the screen 10 inside the cylindrical frame 9 and filling the inside of the fixed barrel 2 with water, then the electric push rod 7 can be controlled to drive the cover body 8 to move down and stick to the top of the fixed barrel 2 to assist in closing the inside of the fixed barrel 2. Then, the driving motor 17 can be controlled to start and drive the driving pulley 25 to rotate. While the driving pulley 25 rotates, the driven pulley 14 can be driven to rotate by the belt body 16. While the driven pulley 14 rotates, the rotating shaft 15, the turntable 13 and the cylindrical frame 9 at the top can be driven to rotate. While the ore inside the cylindrical frame 9 is completely immersed in the cleaning water inside the fixed barrel 2 for soaking and washing, the rotation of the cylindrical frame 9 can also drive the ore inside to flow mutually with the cleaning water inside the fixed barrel 2, which can have an auxiliary flushing effect on the sediment and the like adhered to the outside of the ore. The sediment and the like can be filtered out from the screen 10 into the cleaning water inside the fixed barrel 2 and separated from the ore. After the phosphate rock is washed and the impurities are removed inside the cylindrical frame 9, then the valve on the drain pipe 26 at the rear end of the fixed barrel 2 can be opened to drain the sewage after washing inside the fixed barrel 2. When discharging the ore material after cleaning inside the cylindrical frame 9, the turning handle 19 can be rotated at the rear end of the chassis 1, and the worm 21 can be driven to rotate by the connecting rod 20. While the worm 21 rotates, the first connecting shaft 4 can be driven to rotate by the engaged worm gear 3. While the first connecting shaft 4 rotates, the whole fixed barrel 2 can be driven to turn forward. After turning the top opening of the fixed barrel 2 downward, the ore material inside can be quickly discharged.
