Description

Technical Field

[0001] The present invention relates to the technical field of ore air jet separation, and more particularly to a matrix-type air jet device for ore separation. Background Art

[0002] Ore separation devices primarily use high-pressure gas jets to generate powerful impact forces, effectively removing dust, impurities, and other fine particles from the ore surface. This helps improve the purity of the ore, providing higher-quality raw materials for subsequent handling and processing, thereby increasing ore utilization.

[0003] Among the existing published technical documents, Chinese Patent Publication No. CN117259193A discloses an ore sorting device. This technology mainly involves a fixed connection between the bottom surface of a mounting frame and the upper surface of a fixed frame. A collection box is fixedly installed on the back of the mounting frame. A filter screen is clamped inside the collection box. An air pump is fixedly installed on the back of the fixed frame. The input end of the air pump passes through the collection box and extends to the inside of the collection box. The output end of the air pump passes through the fixed frame and is fixedly connected to an air pipe. The outer surface of the air pipe is fixedly connected to air nozzles arranged at equal distances. This ore sorting device can extract the air in the collection box outward by providing an air pump. The air is directly transported to the air nozzle through the air pipe, so that the air nozzle can blow the dust entering the mounting frame, thereby collecting the dust in a centralized manner. However, this technology still has the following problems.

[0004] During the ore separation process, although the jet contacts the ore so that the lighter impurities therein are blown out, during the jet blowing process, the ore moves and is connected closely, and the jet pipes are all in fixed positions, making it difficult to move them to different horizontal positions and different angles according to actual needs. It is also difficult to perform vertical position-shifting jets. This results in a single airflow direction at the jet position, making it difficult to achieve position-shifting jet separation for different orientations of the ore. This results in more dead angles in the ore jet separation, and the ore jet separation effect is poor. Therefore, a matrix-type jet device for ore separation is needed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: a matrix-type air jet device for ore separation, comprising a partition, a mounting concave plate and an electric cylinder, wherein the mounting concave plate is fixed on one side of the partition, the electric cylinder is fixedly connected to the lower surface of the partition, and the output end of the electric cylinder is connected to a transverse synchronous displacement air jet mechanism; the transverse synchronous displacement air jet mechanism comprises a push block fixedly connected to the output end of the electric cylinder, and the bottom end of the push block is fixedly connected to a linkage bar, and one side of the linkage bar is fixedly connected to a plurality of hinge blocks; the inner wall of each of the hinge blocks is fixedly connected to two pulling shafts, and the outer wall of each of the pulling shafts is rotatably connected to a sleeve block, the inner wall of the sleeve block is rotatably connected to a linkage shaft at a position away from the pulling shaft, and the bottom end of the linkage shaft is fixedly connected to a sleeve shaft block; The inner wall of the sleeve shaft block is rotatably connected to a rotating shaft, and the bottom end of the rotating shaft is fixedly connected to a rectangular deflected air pipe, one side of the rectangular deflected air pipe is fixedly connected to a plurality of matrix nozzles, and the lower surface of the sleeve shaft block is slidably connected to a sliding frame; one end of the sliding frame is provided with an angular synchronous displacement jet mechanism; one end of the linkage bar is provided with a vertical synchronous displacement jet assembly.

[0006] Preferably, multiple hinge blocks are arranged equidistantly from left to right, the vertical cross-section of the hinge block is concave, the center point of the linkage shaft is higher than the center point of the pull shaft, and the cross-sections of the linkage shaft and the pull shaft are both circular; multiple rotating shafts are slidably connected to the sliding frame, the outer wall of the rotating shaft is a smooth surface, and multiple matrix nozzles are arranged in a rectangular distribution. Multiple slip rings are slidably connected to the lower surface of the sliding frame, the slip rings are fixedly connected to the rotating shaft, and the cross-section of the slip ring is a circular ring. An inclined orifice plate is fixedly connected to one side of the sliding frame, and a controller is fixedly connected to one side of the mounting concave plate. A distance sensor is installed on one side of one of the hinge blocks, and the distance sensor is fixedly connected to the hinge block.

[0007] When this technology is in use, the electric cylinder pushes the push block to tilt downward, the linkage bar drives the multiple articulated blocks to tilt downward synchronously, the pull shaft drives the bottom end of the sleeve block to tilt downward, the linkage shaft drives the sleeve shaft block to move right, and the sleeve shaft block drives the rotating shaft to move right along the slide frame. The rotating shaft drives the rectangular deflected air pipe to the right, so that three rectangular deflected air pipes move right, while the other three rectangular deflected air pipes can be synchronously shifted to the left, allowing the multiple matrix nozzles on the rectangular deflected air pipes to spray laterally. At the same time, the guide pipe also diverts the pressurized air into the connecting hose, and the diverter pipe diverts it to the interior of multiple vertical nozzles. These multiple vertical nozzles can spray high-pressure air toward the inclined orifice plate. When the displacement distance sensed by the distance sensor matches the displacement value set by the controller, the controller activates the electric cylinder to tilt and upwardly reposition the push block. The articulated block then tilts and upwardly shifts the two pull shafts. The top of the sleeve block then shifts the linkage shaft leftward, which in turn shifts the sleeve block leftward. The sleeve block then shifts the rotating shaft leftward, which in turn shifts the rectangular deflected air pipes leftward. This synchronizes the leftward shift of three rectangular deflected air pipes, while the rightward shift of the other three allows the pressurized air from the multiple matrix nozzles to be ejected through the holes in the inclined orifice plate.

[0008] Preferably, the angle-synchronized displacement jet mechanism includes a pillar fixedly arranged at one end of the sliding frame; one end of the pillar is fixedly connected to a support bar, and one side of the support bar is fixedly connected to a connecting rod, and the outer wall of the connecting rod is fixedly connected to a plurality of racks; one side of each of the racks is meshingly connected to a displacement gear, and the displacement gear is fixedly connected to the rotating shaft, the cross-sectional shape of the rack is L-shaped, and the rack and the displacement gear are both made of stainless steel.

[0009] When this technology is in use, when multiple rotating shafts move horizontally, the multiple rotating shafts can respectively drive the corresponding multiple shifting gears to rotate back and forth, thereby realizing the reciprocating rotation of the shifting gears. When the shifting gears rotate back and forth, they will drive the rotating shafts to rotate back and forth, and the rotating shafts will drive the rectangular deflected air pipes to rotate back and forth, so that the pressurized air can be reciprocated and sprayed into the holes of the inclined orifice plate, and the ore can be blown by the spray through the holes on the inclined orifice plate.

[0010] Preferably, the vertical synchronous variable position jet assembly includes a connecting shaft fixedly arranged at one end of the linkage bar; the outer wall of the connecting shaft is rotatably connected to a sleeve pull rod, the inner wall of the sleeve pull rod is rotatably connected to a hinged rod at a position away from the connecting shaft, one end of the hinged rod is fixedly connected to a sleeve slider, and the inner wall of the sleeve slider is slidably connected to a guide column; The top of the guide column is fixedly connected to a guide frame, which is also fixedly connected to the mounting recessed plate. The sleeved slider is slidably connected to the guide frame. Multiple vertical nozzles are provided on one side of the sleeved slider. These nozzles are arranged obliquely from bottom to top, one of which is fixedly connected to the sleeved slider. A diverter pipe is provided on one side of the vertical nozzle, and the multiple vertical nozzles are fixedly connected to the diverter pipe. A connecting hose is fixedly connected to the bottom end of the diverter pipe, and a guide pipe is fixedly connected to the top end of the connecting hose. Multiple three-way hoses are fixedly connected to one side of the guide pipe, and the two rectangular deflected air pipes are fixedly connected to the three-way hoses. A booster pump is fixedly installed on the other side of the guide pipe, and the output end of the booster pump is fixedly connected to the suction pipe. The booster pump is fixedly connected to the mounting recessed plate, and the vertical cross-section of the mounting recessed plate is concave.

[0011] When this technology is in use, when the linkage bar tilts downward, it drives the connecting shaft to tilt downward, the sleeve pull rod drives the articulated rod to tilt upward, the sleeve slider tilts upward along the outer wall of the guide column, the sleeve slider simultaneously drives the vertical nozzle to tilt upward, and the diverter pipe drives the connecting hose to stretch. Multiple vertical nozzles can synchronously perform vertical displacement jetting, thereby enabling vertical jet separation of ore on the inclined surface of the inclined orifice plate. When the linkage bar tilts upward and resets, the linkage bar drives the connecting shaft to tilt upward, the bottom end of the sleeve pull rod drives the articulated rod to tilt downward, the sleeve slider causes the vertical nozzle to tilt downward, and the diverter pipe drives the other two vertical nozzles to tilt downward synchronously. Multiple vertical nozzles can achieve vertical displacement jetting along multiple hole positions of the inclined orifice plate.

[0012] The technical effects and advantages of the present invention are as follows: 1. The present invention uses a transverse synchronous displacement jet mechanism. The electric cylinder drives the push block to move obliquely downward, the push block drives the linkage bar to move obliquely downward, the linkage bar drives multiple hinged blocks to move synchronously obliquely downward, the top of the sleeve block drives the linkage shaft to move right, the linkage shaft drives the sleeve shaft block to move right, the three rectangular deflected air pipes move right, and the other three rectangular deflected air pipes can move synchronously to the left. The electric cylinder is started to drive the push block to move obliquely upward and reset, the three linkage shafts move synchronously to the left, and the other three linkage shafts move synchronously to the right. The three rectangular deflected air pipes move synchronously to the left, and the other three rectangular deflected air pipes can move synchronously to the right. The multiple rectangular deflected air pipes can perform transverse synchronous displacement jetting, which can realize displacement jet separation for different orientations of ore, with a wider jet contact range, fewer dead angles for ore jet separation, and greatly improved ore jet separation effect.

[0013] 2. The present invention adopts an angle-synchronized displacement jet mechanism, in which the sliding frame supports the pillar, the pillar supports the support bar, and the support bar supports the connecting rod. When the multiple rotating shafts move horizontally, the multiple rotating shafts can respectively drive the corresponding multiple displacement gears to rotate back and forth. When the displacement gears rotate back and forth, they will drive the rotating shafts to rotate back and forth. The rotating shafts drive the rectangular deflected air pipes to rotate back and forth. Multiple matrix nozzles will realize reciprocating rotation and spray the pressurized air into the holes of the inclined orifice plate. The ore is blown by the jet through the holes on the inclined orifice plate, and displacement jet separation is realized at different angles of the ore. The separation displacement range of the ore is wider, and the impurity jet separation effect is better.

[0014] 3. The present invention uses a vertical synchronous displacement jet assembly. When the linkage bar is tilted downward, the linkage bar will drive the connecting shaft to tilt downward, the hinged rod will drive the sleeve slider to tilt upward, and the sleeve slider will tilt upward along the outer wall of the guide column. The sleeve slider will simultaneously drive the vertical nozzle to tilt upward, and the vertical nozzle will drive the diverter pipe to tilt upward. Multiple vertical nozzles can synchronously perform vertical displacement jetting. When the linkage bar is tilted upward and reset, the linkage bar drives the connecting shaft to tilt upward, and the bottom end of the sleeve pull rod drives the hinged rod to tilt downward. Multiple vertical nozzles can realize vertical displacement jetting along multiple hole positions of the inclined orifice plate, with fewer dead angles for jet separation, a wider jet coverage range, and a better effect of separating ore impurities.

[0015] According to the mutual influence of the above-mentioned multiple effects, firstly, multiple rectangular deflected air pipes can perform synchronous horizontal displacement jet injection, and at the same time, multiple rectangular deflected air pipes can realize displacement jet separation for different angles of ore. Finally, multiple vertical nozzles can realize vertical displacement jet injection along multiple hole positions of the inclined orifice plate. In summary, displacement jet injection at different horizontal positions and displacement jet injection at different angles can be performed according to actual needs. At the same time, displacement jet injection at vertical positions can also be performed, which can realize displacement jet separation for different orientations of ore. There are fewer dead angles for ore jet separation, so that the ore jet separation effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this technical solution, as shown in the attached Figure 5-6As shown, the angle-synchronized variable-speed jet mechanism includes a support 19 fixedly mounted at one end of a slide frame 15. A support bar 20 is fixedly connected to one end of the support bar 19, and a connecting rod 21 is fixedly connected to one side of the support bar 20.

The racks 22 have an L-shaped cross-section, and both the racks 22 and the variable-speed gears 23 are made of stainless steel.

[0034] In this technical solution, as shown in the attached Figure 7-9 As shown, the vertical synchronous displacement jet assembly includes a connecting shaft 24 fixedly arranged at one end of the linkage bar 5; the outer wall of the connecting shaft 24 is rotatably connected to the sleeve pull rod 25, and the inner wall of the sleeve pull rod 25 is rotatably connected to the position away from the connecting shaft 24 with a hinged rod 26, one end of the hinged rod 26 is fixedly connected to the sleeve slider 27, and the inner wall of the sleeve slider 27 is slidably connected to the guide column 28.

[0035] A guide frame 29 is fixedly connected to the top of the guide column 28, and the guide frame 29 is fixedly connected to the mounting recessed plate 2, and the sleeve slider 27 is slidably connected to the guide frame 29; a plurality of vertical nozzles 30 are provided on one side of the sleeve slider 27, and the plurality of vertical nozzles 30 are arranged obliquely from bottom to top, one of the vertical nozzles 30 is fixedly connected to the sleeve slider 27, and a diverter pipe 31 is provided on one side of the vertical nozzle 30, and the plurality of vertical nozzles 30 are fixedly connected to the diverter pipe 31; a connecting hose 32 is fixedly connected to the bottom end of the diverter pipe 31, and a guide pipe 33 is fixedly connected to the top end of the connecting hose 32, and a plurality of three-way hoses 34 are fixedly connected on one side of the guide pipe 33, and the two rectangular deflected air pipes 12 are fixedly connected to the three-way hose 34; a booster pump 35 is fixedly installed on the other side of the guide pipe 33, and a suction pipe 36 is fixedly connected to the output end of the booster pump 35. The boost pump 35 is fixedly connected to the mounting concave plate 2 , and the vertical cross-section of the mounting concave plate 2 is concave.

[0036] The working principle of the matrix type ore separation air jet device of the present invention is as follows: Step 1. When the present invention is installed and used, the mounting concave plate 2 can be fixed on the platform by inserting bolts into the inside of the mounting concave plate 2. At the same time, the mounting concave plate 2 supports the partition 1, and the mounting concave plate 2 supports the partition 1, the partition 1 supports the inclined hole plate 16, and the partition 1 is located below the ore belt conveyor line. In this way, the ore to be separated is transported to the inclined surface of the inclined hole plate 16 through the ore belt conveyor line.

[0037] Step 2. When the present invention performs lateral synchronous displacement jet separation, the booster pump 35 is started by the controller 17. The booster pump 35 pressurizes the external air and allows it to enter the suction pipe 36. The air enters the guide pipe 33 from the suction pipe 36 and is diverted from the guide pipe 33 to multiple three-way hoses 34. The three-way hoses 34 transport the pressurized air to the inside of the rectangular deflected air pipe 12, and the air is transported from the rectangular deflected air pipe 12 to multiple matrix nozzles 13. The multiple matrix nozzles 13 can present a matrix-like injection of pressurized air.

[0038] The electric cylinder 3 is activated by the controller 17. The electric cylinder 3 pushes the push block 4 to tilt downward, which drives the linkage bar 5 to tilt downward. The linkage bar 5 drives multiple hinged blocks 6 to tilt downward synchronously. The hinged blocks 6 can drive the two pull shafts 7 to tilt downward. The pull shaft 7 drives the bottom end of the sleeve block 8 to tilt downward. The top of the sleeve block 8 drives the linkage shaft 9 to move right. The linkage shaft 9 drives the sleeve shaft block 10 to move right. The distance between the two sleeve shaft blocks 10 becomes smaller, and the sleeve shaft block 10 drives the rotating shaft 11 to move right along the slide frame 15. At the same time, the rotating shaft 11 drives the slip ring 14 to move right along the slide frame 15, and the rotating shaft 11 drives the rectangular deflected air pipe 12 to move right. In this way, three rectangular deflected air pipes 12 move right, while the other three rectangular deflected air pipes 12 can move left synchronously, allowing the multiple matrix nozzles 13 on the rectangular deflected air pipes 12 to perform lateral displacement jetting. At the same time, the guide pipe 33 diverts the pressurized air into the connecting hose 32, and enters the diversion pipe 31 from the connecting hose 32. The diversion pipe 31 diverts the air to the interior of multiple vertical nozzles 30, and the multiple vertical nozzles 30 can spray high-pressure air toward the position of the inclined orifice plate 16.

[0039] When the linkage bar 5 drives the distance sensor 18 away from the rack 22, so that the displacement distance value sensed by the distance sensor 18 is the same as the displacement value set by the controller 17, the controller 17 starts the electric cylinder 3 to drive the push block 4 to tilt upward and reset, and the push block 4 drives the linkage bar 5 to make multiple hinge blocks 6 tilt upward, and the hinge block 6 drives the two pull shafts 7 to tilt upward, the pull shaft 7 makes the bottom end of the socket block 8 tilt upward, and the top of the socket block 8 drives the linkage shaft 9 to move left, so that the three linkage shafts 9 move left synchronously, and the other three linkage shafts 9 move right synchronously, the linkage shaft 9 drives the socket shaft block 10 to move left, and the socket shaft block 10 drives the rotating shaft 11 to move left, and the rotating shaft 11 drives the rectangular biased air pipe 12 to move left. In this way, the three rectangular deflected air pipes 12 move to the left synchronously, while the other three rectangular deflected air pipes 12 can move to the right synchronously. As the electric cylinder 3 continues to expand and contract, the three rectangular deflected air pipes 12 and the other three rectangular deflected air pipes 12 can perform lateral synchronous displacement jetting. The pressurized air ejected by the multiple matrix nozzles 13 can pass through the holes on the inclined orifice plate 16 and contact the ore on the inclined orifice plate 16 at different lateral positions for jetting, thereby realizing jet separation of impurities in the ore, and the impurity separation effect is better.

[0040] Step three, when the present invention performs angle synchronous displacement jet separation, the sliding frame 15 is supported by the inclined orifice plate 16, the sliding frame 15 supports the pillar 19, and the pillar 19 supports the support bar 20, the support bar 20 supports the connecting rod 21, and the connecting rod 21 supports the multiple racks 22. When the multiple rotating shafts 11 move laterally, the multiple rotating shafts 11 can respectively drive the corresponding multiple displacement gears 23 to rotate back and forth, and the displacement gears 23 can engage on the racks 22 to realize the reciprocating rotation of the displacement gears 23. When the displacement gears 23 rotate back and forth, they will drive the rotating shaft 11 to rotate back and forth, and the rotating shaft 11 drives the rectangular deflected air pipe 12 to rotate back and forth. The rectangular deflected air pipe 12 drives multiple matrix nozzles 13 to realize the reciprocating rotation of the pressurized air and spray it into the hole position of the inclined orifice plate 16, so that the ore can be blown by the injection through the hole position on the inclined orifice plate 16.

[0041] Step 4: When the present invention performs vertical synchronous displacement jet separation, when the linkage bar 5 tilts downward, the linkage bar 5 drives the connecting shaft 24 to tilt downward, and the connecting shaft 24 drives the top of the sleeve pull rod 25 to tilt downward, and the sleeve pull rod 25 drives the hinge rod 26 to tilt upward. At the same time, the hinge rod 26 drives the sleeve slide 27 to tilt upward, and the sleeve slide 27 moves upward along the outer wall of the guide column 28, and the guide column 28 moves upward along the inner wall of the guide frame 29. The sleeve slide 27 simultaneously drives the vertical nozzle 30 to tilt upward, and the vertical nozzle 30 drives the diverter pipe 31 to tilt upward, and the diverter pipe 31 drives the connecting hose 32 to stretch. At the same time, the diverter pipe 31 drives the other two vertical nozzles 30 to tilt upward. Multiple vertical nozzles 30 can synchronously perform vertical displacement jetting, thereby enabling vertical jet separation of the ore on the inclined surface of the inclined orifice plate 16.

[0042] When the linkage bar 5 tilts upward and resets, the linkage bar 5 drives the connecting shaft 24 to tilt upward, and the connecting shaft 24 causes the top end of the sleeve pull rod 25 to tilt upward. The bottom end of the sleeve pull rod 25 drives the hinged rod 26 to tilt downward, and the hinged rod 26 drives the sleeve slide 27 to tilt downward. The sleeve slide 27 causes the vertical nozzle 30 to tilt downward, and the vertical nozzle 30 drives the diverter pipe 31 to tilt downward. At the same time, the diverter pipe 31 drives the other two vertical nozzles 30 to tilt downward synchronously. The multiple vertical nozzles 30 can realize vertical displacement jet along the multiple holes of the inclined orifice plate 16, thereby realizing vertical displacement jet separation of the ore on the inclined surface of the inclined orifice plate 16, avoiding many dead angles during separation, and the jet coverage is wider, which improves the ore separation effect.
