Description

Technical Field

[0001] The utility model relates to a slurry impurity removal mechanism, belonging to the field of phosphate ore processing. Background Art

[0002] The phosphate rock processing process mainly includes three steps: crushing, screening and wet ball milling. The prepared phosphate rock is loaded into the raw ore bin by a shovel truck, and fed into the jaw crusher by the crane grab for coarse crushing. The coarsely crushed phosphate rock is then screened by a vibrating screen, and the under-screen part is sent to the powder ore bin by a belt conveyor, and the over-screen part is fed into the cone crusher by a belt conveyor for fine crushing. The finely crushed phosphate rock is then screened by a vibrating screen, and the under-screen part goes to the powder ore bin, and the over-screen part returns to the cone crusher; the phosphate rock entering the powder ore bin is fed into the ball mill by a disc feeder, and with the reasonable addition of clean water, a finished slurry with appropriate fineness and moisture is finally obtained. When the phosphate ore that has been coarsely crushed and screened is transported by a belt conveyor, the coarsely crushed phosphate ore for preparing the slurry is treated with magnetic adsorption to remove iron. That is, two electromagnets are arranged on the upper side of the conveyor belt in the belt conveyor. The electromagnets are driven by an electric push rod and move alternately to the top of the conveyor belt. After the electromagnet that has moved to the outside of the conveyor belt is powered off, the iron slag adsorbed on the electromagnet will fall near the belt conveyor under the action of its own gravity. In order to prevent the falling iron slag from being too close to the electromagnet, it is necessary to manually clean the accumulated iron slag around the belt conveyor from time to time. The frequency of cleaning the iron slag is high, which increases the labor intensity. Utility Model Content

[0010] Beneficial effects of the utility model:

[0011] 1. When the electric push rod drives the carrier plate to move, the carrier plate drives the cross bar to move on the lower side of the conveyor belt, and then the two push plates move accordingly, and then the push plates push the iron slag with increased accumulation height flat, so that there is a certain distance between the iron slag and the iron box with the electromagnet installed, to avoid the iron slag from adhering to the electromagnet again due to the increase in height.

[0012] 2. Adjust the length of the L-shaped rod inserted in the straight tube. At this time, the distance between the cross bar and the carrier plate changes.

When the connecting screws are difficult to remove normally using tools such as wrenches due to rust and other reasons, the space between the bracket and the carrier plate can be used to cut off the connecting screws, and then the rectangular block with some connecting screws remaining can be replaced, providing a backup method for removing the connecting screws and minimizing the amount of parts replacement during the disassembly process.

[0014] 4. When the electric push rod drives the carrier plate to move, the carrier plate drives the vertical plate to move. At this time, the guide rod slides in the guide hole relative to the vertical plate. At this time, part of the weight of the carrier plate and other components acts on the positioning plate through the vertical plate and the guide rod, avoiding the weight of the carrier plate and other components from acting completely on the movable end of the electric push rod, so that the electric push rod is balanced and the electric push rod is protected.

The positioning plate 4 is installed at the desired position by bolts to complete the position restriction of the electric push rod 3.

[0029] See also Figure 1 and Figure 5 A guide rod 2 arranged parallel to the electric push rod 3 is provided on the upper side of the electric push rod 3, one end of the guide rod 2 is connected and fixed to the positioning plate 4, a side of the carrier plate 1 facing away from the electric push rod 3 is connected and fixed with a vertical plate 10, a guide hole 18 is opened at the upper position of one side surface of the vertical plate 10, and one end of the guide rod 2 away from the positioning plate 4 passes through the guide hole 18. When the electric push rod 3 drives the carrier plate 1 to move, the carrier plate 1 drives the vertical plate 10 to move. At this time, the guide rod 2 slides in the guide hole 18 relative to the vertical plate 10. At this time, part of the weight of the carrier plate 1 and other components acts on the positioning plate 4 through the vertical plate 10 and the guide rod 2, so as to avoid the weight of the carrier plate 1 and other components acting completely on the movable end of the electric push rod 3, so that the force of the electric push rod 3 is balanced, thereby protecting the electric push rod 3.

[0030] See also Figure 1 , Figure 4 and Figure 6Two iron boxes 9 are installed on the lower surface of the horizontal part of the carrier plate 1, and an electromagnet 20 is installed at the bottom of the iron box 9. During the extension and retraction process of the electric push rod 3, the two iron boxes 9 are alternately moved to the top of the conveyor belt, so that the electromagnet 20 directly above the conveyor belt is energized, and the electromagnet 20 on the outside of the conveyor belt is de-energized, and then the energized electromagnet 20 generates magnetism to make the surface of the iron box 9 directly above the conveyor belt magnetic, thereby adsorbing the iron slag in the phosphate ore.

A cross bar 7 located at the lower side of the conveyor belt is installed at the lower position of the side of the straight tube 6 away from the limit screw 15. Two push plates 8 connected and fixed to the cross bar 7 are sleeved on the cross bar 7 to adjust the length of the L-shaped rod 5 inserted in the straight tube 6. When the height of the cross bar 7 meets the requirement, the relative position of the L-shaped rod 5 and the straight tube 6 can be limited by the limit screw 15 to achieve the purpose of adjusting the height of the push plate 8, and the height of the iron slag being flattened can be adjusted as needed. When the electric push rod 3 drives the carrier plate 1 to move, the carrier plate 1 drives the cross bar 7 to move on the lower side of the conveyor belt, and then the two push plates 8 move accordingly, and then the push plate 8 flattens the iron slag with increased accumulation height, so that there is a certain distance between the iron slag and the iron box 9 equipped with the electromagnet 20, so as to avoid the iron slag from adhering to the electromagnet 20 again due to the increase in height. There is no need to manually clean the iron slag accumulated around the belt conveyor frequently, which reduces the number of cleaning times of the iron slag accumulated around the belt conveyor, which is conducive to reducing labor intensity.

A rectangular block 13 is inserted in the rectangular groove 23, and a threaded hole 22 penetrating the rectangular block 13 is provided on the upper surface of the rectangular block 13. One end of the connecting screw 11 penetrates the through hole 17 and the circular hole 24. The hole 24 is threadedly connected in the threaded hole 22, so that the rectangular block 13 with the threaded hole 22 is inserted into the rectangular groove 23 on the bracket 12, so that the rectangular block 13 and the bracket 12 are plugged in, and the support rod 14 is inserted in the blind hole 19. At this time, under the support of the support rod 14, there is a certain distance between the bracket 12 and the carrier 1, so that the connecting screw 11 passes through the support ear 21, the through hole 17 and the round hole 24 and is screwed into the threaded hole 22 to complete the assembly of the iron box 9 and the carrier 1. When the connecting screw 11 is difficult to be removed normally using a wrench or other tools due to rust or other reasons, the space between the bracket 12 and the carrier 1 can be used to cut off the connecting screw 11, and then the rectangular block 13 with part of the connecting screw 11 remaining can be replaced, providing a backup method for disassembling the connecting screw 11, and reducing the amount of parts replacement to a minimum during the disassembly process.
