Description

Technical Field

[0001] The invention belongs to the technical field of ore sorting, in particular to an ore sorting machine. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Mine dust refers to the general term for various rock and mineral particles produced during mine construction, ore production and transportation. It is extremely harmful and can endanger human health in polluted workplaces, causing pneumoconiosis and skin diseases. It can accelerate mechanical wear, shorten the use time of precision instruments, and reduce visibility at the work site. Some mine dusts can also explode under certain conditions.

[0003] In the current existing technology, after the existing ore is excavated from the inside of the mine, it is sorted by a sorting machine. A large amount of ore dust left over from the excavation and crushing process adheres to the surface of the processed ore particles. The ore dust is extremely harmful. It is generally light and will float in the air with the transportation of ore particles. The traditional ore dust is cleaned by spraying. In this way, the ore is placed flat on the surface of the conveyor belt, and the sprayed water will only penetrate and wet the top surface of the ore, and only the ore dust on the top is cleaned by water. The ore dust hidden on the bottom surface of the ore particles cannot contact the water, and will not flow with the water, which makes the ore dust cleaning not thorough enough. In addition, the ore particles are exposed to the outside world in the traditional spraying method. Some of the cleaned ore dust will accumulate on the ground, causing the accumulation of ore dust. After the water dries up, the ore dust will be scattered under the drive of the air. The ore particles continue to move with the conveyor belt, and the ore dust is scattered in the air again under the drive of the gas, resulting in the problem that the ore dust cannot be effectively cleaned.

[0004] To this end, the present invention provides an ore sorting machine. Summary of the invention

[0021] 3. The ore sorting machine described in the present invention guides the ore particles into the interior of the ore screening drum, and at the same time cooperates with the motor on the outer surface of the supporting lower pressure arm to rotate the transmission rod. When the transmission rod rotates, it will drive the ore screening drum to rotate, and at the same time, it will drive the ore particles inside the ore screening drum to be continuously stirred and rolled. When the ore screening drum is stirred and rolled, the ore will be driven by the push plate on the inner wall of the ore screening drum to slide. When the push plate pushes the ore particles to a higher position, the surface of the ore particles is no longer blocked by the push plate, and the ore particles will fall downward, so that the ore particles collide with the inner wall of the ore screening drum or the surface of the ore, and the ore dust remaining on the surface of the ore particles is cleaned up by the impact force, and then sprayed out by the water inside the semicircular hollow cylinder, so as to achieve the effect of dust reduction on the surface of the ore particles, and then the ore dust is taken away by the flowing water for cleaning.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 8 As shown, an ore sorting machine according to an embodiment of the present invention comprises a base platform 11 and support uprights 12 symmetrically fixedly mounted on the top surface of the base platform 11 and located at the edge positions on both sides, a dust collecting box 14 is fixedly mounted on the top surface of the base platform 11 and located at the middle position, a support leg 13 is symmetrically fixedly mounted on the top surface of the base platform 11 and located at the edge positions on both sides of the dust collecting box 14, a support leg 2 15 is fixedly mounted on the edge position of one side of the top of the base platform 11, and a self-vibrating dust cleaning unit is arranged on the outer surface of the support leg 2 15. The self-vibrating dust cleaning unit comprises a transmission rod 153 fixedly arranged on the outer surface of the base platform 11 and the top of the dust collecting box 14, two groups of support frames 154 are fixedly installed on the outer surface of the transmission rod 153 and located in the middle position, and an ore screening cylinder 155 sleeved on the outer surface of the transmission rod 153 is fixedly connected to the outer surface of the support frame 154, and screening holes are opened on the outer surface of the ore screening cylinder 155, and a counterweight block 156 is arranged on the outer surface of the transmission rod 153 and on the inner wall surface of the two groups of support frames 154;

[0034] A stone collecting housing 151 movably sleeved on the outer surface of the transmission rod 153 is fixedly connected to the top surface of the supporting leg 15, a sleeve 152 movably sleeved on the outer surface of the transmission rod 153 is fixedly connected to the bottom inner wall of the stone collecting housing 151, and a motor 157 is detachably mounted on one end of the transmission rod 153;

[0035] A support lower pressure arm 124 movably sleeved on the outer surface of the transmission rod 153 is provided on the outer surface of the support vertical plate 12 , and the outer surface of the motor 157 is fixedly connected to the inner wall surface of the support lower pressure arm 124 .

[0036] When the self-vibrating dust cleaning unit provided by the present invention is used, it cooperates with the ore sorting machine to transport the sorted ore, cooperates with the stone collecting shell 151 on the top of the supporting leg 15 to collect the ore sorted by the sorting machine, and utilizes the inclination angle of the stone collecting shell 151 to make the fallen ore easier to slide down and control the sliding path of the ore, so that the granular ore passing through the inside of the stone collecting shell 151 slides into the inside of the ore screening cylinder 155, wherein the motor 157 is used to drive the transmission rod 153 to rotate, and when the transmission rod 153 rotates, it will drive the ore The ore screening drum 155 rotates, and the ore particles inside the ore screening drum 155 are stirred and rolled continuously. When the ore screening drum 155 is stirred and rolled, the ore is driven to slide together with the push plate on the inner wall of the ore screening drum 155. When the push plate pushes the ore particles to a higher position, the surface of the ore particles is no longer blocked by the push plate, and the ore particles fall downward, so that the ore particles collide with the inner wall of the ore screening drum 155 or the surface of the ore, and the impact force is used to clean up the ore dust remaining on the surface of the ore particles. Then, the water sprayed inside the semicircular hollow cylinder 131 is used to reduce the ore dust on the surface of the ore particles, and then the flowing water is sprayed on the surface of the ore screening cylinder 155. The sieve holes on the outer surface of the ore screening cylinder 155 are used to make the clean water on the outer surface of the ore screening cylinder 155 pass through the sieve holes into the interior of the ore screening cylinder 155, and contact the ore dust accumulated in the internal space of the ore screening cylinder 155, and then wet the ore dust and reduce the dust, so as to achieve the effect of taking away the ore dust by the flow of water for cleaning, and the ore dust is absorbed. The dusty water will penetrate the surface of the ore screening cylinder 155 through the screening holes on the bottom surface of the ore screening cylinder 155 under the drive of its own gravity, and the dripping water will vertically drop into the dust collecting box 14 to collect the water and ore dust, thus avoiding that after the ore particles are sorted out inside the sorting machine, there will be a certain amount of ore dust remaining on the surface of the ore, and the ore dust will move with the conveyor, and then in the process of transportation, the dust will spread into the air and cause harm to the respiratory system, and the mineral dust is also easy to cause damage to the eyes;

[0037] When the transmission rod 153 rotates, the counterweight 156 on the outer surface of the transmission rod 153 is driven to rotate. When the transmission rod 153 rotates, the center of gravity of the transmission rod 153 shaft is centered on the central axis of the transmission rod 153, so that the transmission rod 153 can maintain a stable state when it rotates. When the transmission rod 153 rotates, the counterweight 156 is driven to rotate. Since the counterweight 156 is added, there are more convex counterweights on the surface of the transmission rod 153, so that the transmission rod 153 will be pulled by the protruding counterweight 156 when it rotates, thereby destroying the stable rotation state of the transmission rod 153, so that the transmission rod 153 will be inertia when it rotates. The transmission rod 153 and the ore screening drum 155 are fixedly connected together by the support frame 154, so that the ore screening drum 155 will swing and vibrate together with the transmission rod 153. When the ore screening drum 155 swings and vibrates, the ore particles inside the ore screening drum 155 will vibrate. Each vibration of the ore screening drum 155 will knock away the ore particles accumulated inside the ore screening drum 155. In the process of splashing, the ore particles will spread and expand around, so that the central area of ​​the accumulated ore particles is spread. When the ore particles spread, the ore particles in the central area will penetrate into the ore screening drum 155 with the outside world. As the ore particles continue to splash and diffuse inside the ore screening cylinder 155, since the weight and volume of the ore particles are greater than that of water, the inertial speed of the ore particles will be greater than that of water, so that when the surface of the ore particles is hit, the instantaneous impact force generated will separate the water adhering to the surface of the ore particles, thereby forming solid-liquid separation. As the water continues to accumulate, the excess water will pass through the screening holes on the surface of the ore screening cylinder 155 and be discharged. In addition, the flying ore will hit the inner wall of the ore screening cylinder 155, and the instantaneous impact force generated when the ore hits can be used to shake off some of the sand or ore dust that has formed agglomerates adhering to the surface of the ore. The ore particles are cleaned up and discharged along with the flow of water, which avoids the traditional drum screening that uses rotation to separate ore particles and ore dust. However, there are relatively many ore particles inside the drum screening. When the screening drum is rotated, the ore particles will accumulate on the inner bottom surface of the screening drum due to their own gravity, and the accumulated ore particles will be turned over. Since the push plate is relatively small, the amount of ore particles driven at one time is relatively small, and only a small amount of the deepest ore particles can be exchanged with the outermost ore particles. The amount of ore particles in the middle part exchanged with the outer ore particles is relatively small, which will cause some of the ore particles to be diverted and discharged before effective dust removal.

[0038] Furthermore, if Figure 1 - Figure 3 and Figure 5 As shown, a circular groove hole 121 is opened on the inner wall surface of the supporting vertical plate 12, and a sliding rod 123 fixedly connected to the bottom surface of the supporting lower pressure arm 124 is movably sleeved on the inner wall surface of the circular groove hole 121, and the bottom end of the sliding rod 123 is fixedly connected to a damping vibration reduction spring 122 arranged on the inner wall surface of the bottom of the supporting vertical plate 12.

[0039] When the circular slot hole 121, the damping spring 122, the sliding rod 123 and the supporting lower pressing arm 124 provided by the present invention are in use, when the motor 157 on the outer surface of the supporting lower pressing arm 124 drives the transmission rod 153 to rotate, the transmission rod 153 will drive the counterweight block 156 on the outer surface of the transmission rod 153 to rotate while rotating. Since the transmission rod 153 will generate a pulling force due to the counterweight block 156 when rotating, the stable rotation state of the transmission rod 153 is destroyed, causing the transmission rod 153 to vibrate. Since the two ends of the transmission rod 153 are respectively movably sleeved on the supporting lower pressing arm 12 4, and the two ends of the support lower pressure arm 124 are respectively fixedly connected to one end of the slide bar 123. When the ore screening cylinder 155 generates a thrust for swinging left and right, it will drive the support lower pressure arm 124 to swing left and right and up and down. Since the surface of the slide bar 123 is movably sleeved on the inner wall of the circular groove hole 121, the left and right swinging range and space of the slide bar 123 are limited, and the left and right swinging range of the transmission rod 153 will be limited to a very small space. When the ore screening cylinder 155 generates an up and down swinging range, there is no space limit on the upper and lower sides of the slide bar 123, so that The ore screening cylinder 155 will have a large up and down swing amplitude, so that the ore inside the ore screening cylinder 155 will bounce and vibrate with the up and down swing of the ore screening cylinder 155, and the bouncing ore will hit the inner wall of the ore screening cylinder 155. The instantaneous impact force generated by the collision of the ore can achieve the effect of shaking off and cleaning some gravel or ore dust that has formed agglomerates adhering to the surface of the ore. Since the water sprayed from the semicircular hollow cylinder 131 will cover the entire top surface of the ore screening cylinder 155, the water will screen along the surface of the ore screening cylinder 155. The water will enter the interior of the ore screening cylinder 155 through the screening holes. A part of the water will slide to both sides on the surface of the ore screening cylinder 155, and then the surface of the ore screening cylinder 155 will be covered with water to reduce the dust inside the ore screening cylinder 155. The dust will leak out due to the screening holes. The water that penetrates into the ore screening cylinder 155 will soak, moisten and reduce the dust of the ore dust floating in the middle of the ore screening cylinder 155. As the water continues to accumulate inside the ore screening cylinder 155, the excess water will pass through the screening holes on the bottom surface of the ore screening cylinder 155 and be discharged.

[0040] Furthermore, if Figure 1 and Figure 3 - Figure 7As shown, a semicircular hollow cylinder 131 is fixedly connected to the top of the supporting leg 13, the inner wall of the semicircular hollow cylinder 131 is arranged on the top outer surface of the ore screening cylinder 155, a water dispersion net 132 is arranged on the bottom inner wall of the semicircular hollow cylinder 131, a water pipe 133 is fixedly connected to the bottom surface of one side of the semicircular hollow cylinder 131, and the other end of the water pipe 133 is fixedly connected to a water pump 134 arranged on the top outer surface of the foundation platform 11.

[0041] When the semicircular hollow cylinder 131, the water dispersion net 132 and the water guide pipe 133 provided by the present invention are in use, the water pump 134 injects the absorbed clean water into the interior of the semicircular hollow cylinder 131 through the water guide pipe 133, and at the same time cooperates with the water dispersion net 132 on the bottom surface of the semicircular hollow cylinder 131 to spray out the clean water inside the semicircular hollow cylinder 131. At the same time, the curvature of the semicircular hollow cylinder 131 is used to make the clean water sprayed by the water dispersion net 132 cover the top outer surface of the ore screening cylinder 155, and the water will pass through the screening holes on the surface of the ore screening cylinder 155 and enter the interior of the ore screening cylinder 155, so as to screen the ore screening cylinder 155. The ore dust inside the semicircular hollow cylinder 131 is wetted and dusted, and then the ore dust is discharged into the dust collecting box 14 through the ore screening cylinder 155 by the fluidity of water, and the outer surface of the ore screening cylinder 155 is completely soaked, so that the dust cannot leak out through the holes on the surface of the ore screening cylinder 155, thereby achieving the effect of dust reduction treatment on the ore dust on the surface of the ore particles. At the same time, the sprayed water will also reduce the leakage of ore dust. When the water sprayed from the semicircular hollow cylinder 131 covers the top surface of the ore screening cylinder 155, the water will enter the ore screening cylinder 155 along the surface screening holes of the ore screening cylinder 155. The water will go to the inside of the ore screening cylinder 155, and part of the water will slide to both sides on the surface of the ore screening cylinder 155. The centrifugal force generated by the rotation of the ore screening cylinder 155 will throw away part of the water attached to the surface of the ore screening cylinder 155, and this part of the water will increase the humidity of the outside air, greatly reducing the floating density of dust in the air. The water covering the surface of the ore screening cylinder 155 will enter the inside of the ore screening cylinder 155 through the screening holes. Since the water is in a liquid state, a small part of the water will move with the rotation of the ore screening cylinder 155, and most of the water will move under its own gravity. The water vertically adheres to the surface of the ore particles to moisten the ore particles. In the process of falling, the water will penetrate, moisten and reduce the dust of the ore dust floating in the middle of the ore screening drum 155. As the water continues to accumulate inside the ore screening drum 155, the excess water will pass through the screening holes on the bottom surface of the ore screening drum 155 and be discharged. Since the rotation speed of the ore screening drum 155 is not very fast, the surface of the ore screening drum 155 will not generate excessive centrifugal force, so that most of the water will not change direction with the rotation of the ore screening drum 155 and will be discharged under its own gravity.

[0042] Furthermore, if Figure 1 - Figure 5 and Figure 7 - Figure 8 As shown, a plurality of drainage holes 141 are symmetrically provided on the inner wall surfaces of the bottom of both sides of the dust box 14, a support pad 142 is fixedly connected to the inner wall surface of the dust box 14 and located in the middle position, an elastic wire 143 is fixedly connected to the top surface of the support pad 142, a sieve plate 144 arranged on the inner wall surface of the dust box 14 is movably overlapped on the top surface of the elastic wire 143, two semicircular grooves are provided on the outer surface of the sieve plate 144, and the diameter length value of the wrapping tube 152 is greater than the diameter length value of the transmission rod 153.

[0043] When the dust box 14 and the sieve plate 144 provided by the present invention are in use, water carrying ore dust will enter the interior of the dust box 14, and the dripping water will be blocked and filtered by the sieve plate 144. At the same time, the semicircular grooves on the outer surface of the sieve plate 144 will be used to concentrate the filtered ore dust at the lowest point on the inner side of the semicircular grooves, so that the ore dust will not completely cover the surface of the sieve plate 144, thereby reducing the filtering effect of the sieve plate 144 on water. Moreover, under the push of water, the ore dust adhering to the walls on both sides of the semicircular grooves will be pushed and concentrated.

[0044] The working principle provided by the present invention is as follows: the ore sorting machine is cooperated to transport the sorted ore, the stone collecting shell 151 on the top of the supporting leg 15 is cooperated to collect the ore sorted by the sorting machine, and the sliding force of the fallen ore is increased by cooperating with the inclination angle of the stone collecting shell 151 and the sliding path of the ore is controlled and processed, so that the granular ore inside the stone collecting shell 151 slides into the inside of the ore screening cylinder 155, and at the same time, the motor 157 on the outer surface of the supporting lower pressure arm 124 is cooperated to rotate the transmission rod 153, and when the transmission rod 153 rotates, it will drive the ore screening cylinder 155 to rotate, and when it rotates, it will drive the ore screening cylinder 155 The ore particles inside are constantly stirred and rolled, and when the ore screening cylinder 155 is stirred and rolled, the ore will be driven to slide together with the push plate on the inner wall of the ore screening cylinder 155. When the push plate pushes the ore particles to a higher position, the surface of the ore particles is no longer blocked by the push plate, and the ore particles will fall down, so that the ore particles collide with the inner wall of the ore screening cylinder 155 or the surface of the ore, and the ore dust remaining on the surface of the ore particles is cleaned up by the impact force, and then the water inside the semicircular hollow cylinder 131 is sprayed out, so as to achieve the effect of dust reduction on the surface of the ore particles, and then the ore dust is taken away by the flowing water for cleaning;

[0045] The motor 157 on the outer surface of the support lower pressure arm 124 is used to rotate the transmission rod 153. When the transmission rod 153 rotates, the counterweight block 156 on the outer surface of the transmission rod 153 is driven to rotate. When the transmission rod 153 rotates, the center of gravity of the transmission rod 153 shaft will be centered on the central axis of the transmission rod 153, so that the transmission rod 153 can maintain a stable state when it rotates. When the transmission rod 153 rotates, it will drive the counterweight block 156 to rotate. Due to the addition of the counterweight block 156, there are more convex counterweights on the surface of the transmission rod 153, so that the transmission rod 153 will be pulled by the protruding counterweight block 156 when it rotates. , thereby destroying the stable rotation state of the transmission rod 153, so that the transmission rod 153 will swing and vibrate due to inertia when rotating, and the transmission rod 153 and the ore screening drum 155 are fixedly connected together by the support frame 154, so that the ore screening drum 155 will swing and vibrate together with the transmission rod 153. When the ore screening drum 155 swings and vibrates, it will vibrate the ore particles inside the ore screening drum 155, and the flying ore will hit the inner wall surface of the ore screening drum 155. The instantaneous impact force generated by the collision of the ore can achieve the effect of shaking off and cleaning some gravel or ore dust that has formed agglomerates adhering to the surface of the ore;

[0046] When the motor 157 on the outer surface of the support lower pressure arm 124 rotates the transmission rod 153, and the transmission rod 153 drives the counterweight block 156 on the outer surface of the transmission rod 153 to rotate while rotating. Since the transmission rod 153 will generate a pulling force due to the counterweight block 156 when rotating, the stable rotation state of the transmission rod 153 is destroyed, causing the transmission rod 153 to vibrate. Since the two ends of the transmission rod 153 are respectively movably sleeved on the inner wall surface of the support lower pressure arm 124, and the two ends of the support lower pressure arm 124 are respectively fixedly connected to one end of the slide bar 123, when the ore screening cylinder 155 generates a thrust for swinging left and right, it will drive the support lower pressure arm 124 to swing left and right and up and down. Connected to the inner wall of the circular groove hole 121, the left and right swinging amplitude and space of the slide bar 123 are limited, which results in the left and right swinging amplitude of the transmission rod 153 being limited in a very small space. When the ore screening cylinder 155 produces an up and down swinging amplitude, the upper and lower sides of the slide bar 123 are not spatially limited, so that the ore screening cylinder 155 has a larger up and down swinging amplitude, and the ore inside the ore screening cylinder 155 will bounce and vibrate with the up and down swing of the ore screening cylinder 155. The bouncing ore will collide with the inner wall of the ore screening cylinder 155, and the instantaneous impact force generated by the collision of the ore can be used to shake off and clean up some gravel or ore dust that has formed agglomerates adhering to the surface of the ore.
