Background

Shot blasting machines (also called sand blasting machines and sand blasting machines) are casting equipment which utilize high-speed shots thrown by a shot blasting machine to clean or strengthen the surface of a casting. Wherein the projectile is a reusable device. However, in the process of the shot contacting the casting, the shot adheres to the surface of the casting (for example, chips scraped off after the casting itself is rubbed, chips of a coating on the surface of the casting, or chips of an oxide layer on the surface of the casting), and in order to avoid the influence of the attachments on the shot blasting, the shot after use needs to be separated to remove the attachments in the shot.

The conventional shot blasting machine separation device is usually arranged at a high position, and shot blasting mixed with attachments needs to be manually or mechanically conveyed to the high position, and then shot blasting and attachment separation is directly completed at the high position; the separated shot is in a high position and has larger gravitational potential energy so as to be conveniently input into a shot blasting machine to realize shot blasting work.

The direct separation at high position is not favorable to the clearance of attachment, also is not favorable to the maintenance and the maintenance of equipment.

The application provides a promote separator includes: the primary lifting mechanism 100 is used for conveying the mixed material at the first station to a second station, and the second station is higher than the first station; the primary separating mechanism 200 is used for receiving the mixed materials conveyed by the primary lifting mechanism 100, and the mixed materials can reach a third station through the primary separating mechanism 200, wherein the third station is lower than the second station; and the secondary lifting mechanism 300 is used for conveying the mixed material at the third station to a fourth station, and the fourth station is higher than the third station.

In a specific embodiment, the lifting and separating device provided by the application is used in a shot blasting machine and used for processing used shots so as to separate the shots from attachments. Since the accretion is usually a chip or dust on the surface of the casting, the accretion is different from at least one of the shape, size and quality of the shot.

It should be noted that the mixed material described in this application does not refer to a certain material or several materials, and the materials entering the lifting and separating device and being lifted and separated are all referred to as mixed materials in this application. For example, when the lifting separation device provided by the application is used for a shot blasting machine, the mixed material can represent shot, an attachment, shot shots and/or an attachment; specifically, the mixed material which just enters the lifting separation device and is not subjected to separation treatment comprises the shot and the attachments, and the separated mixed material is the attachments or the shot after separation.

In other embodiments, the lifting separation device provided by the application can also be used for separating grains in feed processing, or separating ore raw materials in cement production and the like. The application does not limit the specific functional objectives of the lift-off separation device.

Wherein, first-stage separating mechanism 200 includes: a primary separation bin 210 communicating the second station and the third station; and the primary screen 220 is arranged in the primary separation bin 210 and is used for screening out large-particle materials in the mixed materials.

The primary separation bin 210 is used for limiting the circulation space of the mixed materials, and ensuring that the mixed materials go to the third station and cannot be separated from the lifting separation device midway.

The primary screen 220 has a mesh on the surface thereof, which is designed according to the shape of the target material to be separated. For example, when the target material is a bullet, the bullet is spherical, and the mesh can be round or square. The mesh is slightly larger than the maximum peripheral surface of the target material, the target material can easily pass through the mesh, but the non-target material is left by the mesh wires constituting the mesh.

When the target material is a shot, because the spherical object is good at rolling, even if the shot cannot directly fall into the mesh and is impacted by other materials, the shot can roll on the surface of the first-level screen 220, and then other meshes are searched to pass through the first-level screen 220. In this case, the non-target material is attached matter, which is usually in the form of a sheet or a block, is easily blocked by the mesh wire, and is not easily moved on the first-stage screen 220.

Optionally, at least two primary screens 220 are disposed in the primary separation bin 210, and the at least two primary screens 220 are spaced in the up-down direction.

At this moment, the mixed material passes through the primary separation bin 210, falls to the in-process of third station from the second station, can pass through each one-level screen 220 in proper order to carry out the separation many times, and then improve the separation effect.

Alternatively, the mesh openings of at least two primary screens 220 are gradually reduced from top to bottom.

It will be readily appreciated that non-target materials, unlike target materials, are generally not of similar shape and size, and therefore, when the mesh openings of at least two primary screens 220 are not changed, materials that do not meet the requirements of the mesh openings are essentially trapped when passing through the first primary screen 220, which results in a rapid build-up of non-target materials on the first primary screen 220, and therefore, an increased number of cleanings of the primary screens 220 is required.

In any two first-stage screens 220, the aperture of the lower first-stage screen 220 is smaller than that of the upper first-stage screen 220, the first-stage screen 220 can leave the non-target material with the largest particles, the second first-stage screen 220 can leave the non-target material … … with smaller particles, and the like, and at least two first-stage screens 220 can uniformly retain the non-target materials with different particle sizes, so that the situation that the upper first-stage screen 220 needs to be cleaned frequently due to a large action range is avoided.

To sum up, the mixed material at the low position (the first station) is conveyed to the high position (the second station) by arranging the first-stage lifting mechanism 100, so that the separation effect is optimized by the dead weight after the mixed material enters the first-stage separation mechanism 200.

It is easy to understand that because the quality of each material is different, the material with larger quality drops fastly, the material with smaller quality drops fastly in the process of falling to the third station from the second station. For example, in separating the shot from the additive, the shot is generally a steel ball, and the additive is generally a dust or flake, so the shot has a greater mass than the additive, and therefore, during the dropping process, the shot will preferentially contact the primary screen 220, thereby avoiding the primary screen 220 from accumulating non-target material before the shot is allowed to pass through.

Meanwhile, in the process that the mixed material falls from a high position to a low position, the falling speed is increased under the influence of the gravity acceleration, and the movement of the target material which does not directly pass through the first-stage screen 220 on the surface of the first-stage screen 220 and the searching of other meshes are facilitated to realize the separation.

Through locating one-level separating mechanism 200 between high level (second station) and low level (third station), ground can be close to the mounted position of one-level screen cloth 220, on the one hand, is convenient for the separation condition of manual observation mixing material, and on the other hand, the operating personnel of being convenient for clears up or overhauls one-level screen cloth 220.

The mixed material at the low position (the third station) is conveyed to the high position (the fourth station) by arranging the second-stage lifting mechanism 300, so that the separated target material has larger gravitational potential energy, and the target material can flow into the material receiving equipment through a pipeline under the action of gravity. For example, when the target material is shot, the shot can fall into the shot blasting device from top to bottom due to the fact that the shot has larger gravitational potential energy at the fourth station, and therefore the shot blasting device can throw out and strike castings conveniently.

The specific configurations of the first-stage lifting mechanism 100 and the second-stage lifting mechanism 300 are not limited in this application, as long as the two can convey the mixed material from the low position to the high position.

Wherein, the first-stage lifting mechanism 100 and the second-stage lifting mechanism 300 can adopt a transportation structure such as a robot, a crane, etc. The specific configurations of the primary lifting mechanism 100 and the secondary lifting mechanism 300 may be identical or may be different.

In one embodiment, referring to fig. 1 to 3, the primary lifting mechanism 100 and the secondary lifting mechanism 300 have the same specific configuration, and the primary lifting mechanism 100 is taken as an example for illustration. The primary lifting mechanism 100 includes: a lift bin 110; a driving wheel 120 and a driven wheel 130 which are provided in the lifting bin 110 and are spaced apart in the vertical direction; the driving member is connected with the driving wheel 120 and used for driving the driving wheel 120 to rotate; a belt 140 sleeved on the driving wheel 120 and the driven wheel 130; and a plurality of hoppers 150 arranged on the belt 140 at intervals.

The lifting bin 110 is used for limiting the circulation space of the mixed materials, and the mixed materials are prevented from being separated from the lifting separation device in the process that the hopper 150 operates the mixed materials.

Optionally, the lifting bin 110 is in communication with a material handling apparatus. The material utilization device produces a mixed material and can deliver the mixed material to the lift bin 110.

For example, the material using equipment is a shot blasting chamber, a casting to be processed is placed in the shot blasting chamber, a shot blasting machine can throw high-speed shots to the casting, and the shots fall into the bottom of the shot blasting chamber after contacting the casting. The bottom of the shot blasting chamber is provided with a screw propeller which can push the shots and attachments into the lifting bin 110.

Optionally, the mixed material input by the material using equipment is accumulated at the bottom of the lifting bin 110. One of the driving wheel 120 and the driven wheel 130 is disposed near the bin bottom of the lifting bin 110, and the hopper 150 can scoop up the mixed material when moving to the bin bottom of the lifting bin 110.

In the embodiment shown in fig. 2, the driving pulley 120 and the driven pulley 130 are spaced apart in the up-down direction, and both rotate clockwise. At this time, the opening of the hopper 150 on the left side of the driving wheel 120 and the driven wheel 130 faces upward, and the opening of the hopper 150 on the right side of the driving wheel 120 and the driven wheel 130 faces downward; the primary separation chamber 210 is disposed at the right side of the driving wheel 120 and the driven wheel 130, and the inlet of the primary separation chamber 210 is disposed opposite to the driven wheel 130.

In this embodiment, the belt 140 circulates clockwise, and the hopper 150 located at the right side of the driving wheel 120 and the driven wheel 130 moves from top to bottom, gradually approaching the bottom of the lifting bin 110; after scooping the mixed material, the hopper 150 moves to the left side of the driving wheel 120 and the driven wheel 130 with the mixed material and moves from bottom to top; after the hopper 150 moves to the driven wheel 130, the opening is turned over, and the belt 140 has a certain rotation speed, so that the mixed material in the hopper 150 can be thrown out and then enter the primary separation bin 210 through the inlet.

Because the lifting bin 110 encloses the driving wheel 120, the driven wheel 130, the belt 140 and the hopper 150, even if the mixed materials fall out of the hopper 150 in the movement process of the hopper 150, the mixed materials can be received by other hoppers 150 or fall back to the bin bottom of the lifting bin 110, and therefore, the utilization rate of the mixed materials can be ensured.

Wherein, the driving piece can adopt a motor, a rotary cylinder and other rotation driving components.

Along the extending direction of the belt 140, the belt 140 is provided with a plurality of hoppers 150 at equal intervals, and the plurality of hoppers 150 cooperate to continuously scoop and throw out the mixed material, so that the mixed material orderly and continuously enters the primary separating mechanism 200.

Referring collectively to fig. 3, secondary lift mechanism 300 also includes lift cartridge 310, drive pulley 320, driven pulley 330, belt 340, and hopper 350. The structures and functions of the lifting bin 310, the driving wheel 320, the driven wheel 330, the belt 340 and the hopper 350 refer to the description of the primary lifting mechanism 100, and are not described in detail herein.

Since the primary lifting mechanism 100 and the secondary lifting mechanism 300 are both connected to the primary separation bin 210, in one embodiment, they may be disposed on different sides of the primary separation bin 210.

In another embodiment, referring to fig. 1 to 3, the primary lifting mechanism 100 and the secondary lifting mechanism 300 are disposed on the same side of the primary separating bin 210, and are disposed side by side, so as to effectively reduce the floor space of the whole lifting and separating device.

Optionally, an access door 111 is provided on the lift bin 110/310 to facilitate operator access to the interior of the lift bin 110/310.

For example, in the embodiment shown in fig. 1, the access door 111 is disposed at the side of the lifting bin 110/310 and near the bottom of the lifting bin 110/310, so that an operator can access the mixed materials in the lifting bin 110/310 through the access door 111.

It should be noted that in the embodiment shown in fig. 1 to 3, the lifting strokes of the primary lifting mechanism 100 and the secondary lifting mechanism 300 are different, and the secondary lifting mechanism 300 is higher than the primary lifting mechanism 100, that is, the fourth station is higher than the second station.

As will be readily understood, the second station is used to optimise the separation and the fourth station is used to ensure the gravitational potential of the mixed materials. The two stations are not arranged in the same height because the two stations are arranged in different purposes. In actual use, the lifting strokes of the primary lifting mechanism 100 and the secondary lifting mechanism 300 can be adjusted according to the requirements of separation and gravitational potential energy.

It should also be noted that in the embodiment shown in fig. 1 to 3, the turning directions of the belts 140 and 340 in the primary lifting mechanism 100 and the secondary lifting mechanism 300 are identical, that is, the moving directions of the driving wheels 120 and 320 and the driven wheels 130 and 330 are identical. Therefore, the two sets of lifting mechanisms 100 and 300 may use the same driving element, and at this time, the two driving wheels 120 and 320 are coaxially disposed, the driving element is connected to one driving wheel 120 or 320, and the driving element operates to realize the synchronous rotation of the two driving wheels 120 and 320, and further realize the synchronous movement of the two sets of belts 140 and 340 and the two sets of hoppers 150/350.

Of course, if the rotation directions of the two sets of belts 140 and 340 in the first-stage lifting mechanism 100 and the second-stage lifting mechanism 300 are not consistent, or the operation parameters such as the rotation speeds of the two sets of belts 140 and 340 are different, the two sets of lifting mechanisms 100 and 300 need to be respectively provided with a driving member to realize the movement of the belts.

Optionally, the primary separation mechanism 200 further comprises: the first material guide plate 231 is arranged in the primary separation bin 210 and is opposite to the inlet of the primary separation bin 210; the second material guide plate 232 is arranged in the primary separation bin 210, is positioned below the first material guide plate 231 and is positioned above the primary screen 220; the first material guide plate 231 and the second material guide plate 232 are oppositely arranged, the first material guide plate 231 extends obliquely towards the second material guide plate 232, and the second material guide plate 232 extends obliquely towards the first-stage screen 220; the mixture enters the primary separating mechanism 200 through the inlet of the primary separating bin 210, and after contacting the first material guiding plate 231, the mixture can move towards the second material guiding plate 232 along the first material guiding plate 231, and after contacting the second material guiding plate 232, the mixture can move towards the primary screen 220 along the second material guiding plate 232.

Referring specifically to fig. 2, in the illustrated embodiment, the inlet of the primary separation chamber 210, which communicates with the second station, is disposed at the upper portion of the left wall thereof; the first material guide plate 231 is arranged on the right wall of the primary separation bin 210, and the first material guide plate 231 is over against the inlet and inclines leftwards from top to bottom; the second material guiding plate 232 is disposed on the left wall of the primary separation bin 210, and the second material guiding plate 232 is disposed below the inlet of the primary separation bin 210, directly faces the left end of the first material guiding plate 231, and inclines from top to bottom to the right.

In this embodiment, after entering the primary separation bin 210, the mixed material is thrown onto the first material guiding plate 231, slides onto the second material guiding plate 232 along the first material guiding plate 231, and slides onto the primary screen 220 along the second material guiding plate 232 under the influence of self-weight and motion inertia.

By arranging the inclined guide plates in a hierarchical manner, on one hand, the mixed materials entering the primary separation bin 210 can be prevented from directly falling onto the primary screen 220 from a high position, so that the primary screen 220 and the mixed materials are prevented from colliding at a high speed, and the service life and the safety of equipment and the mixed materials are facilitated; on the other hand, the height space of the primary separation bin 210 can be fully utilized, the movement path of the mixed material from the inlet to the primary separation bin 210 is prolonged, and the stability and the continuity of the separation work are facilitated.

Optionally, the primary separating mechanism 200 further includes a third material guiding plate 233, which is disposed in the primary separating bin 210, below the second material guiding plate 232, and above the primary screen 220; the third material guide plate 233 and the second material guide plate 232 are disposed opposite to each other, the second material guide plate 232 extends obliquely toward the third material guide plate 233, and the third material guide plate 233 extends obliquely toward the primary screen 220.

Specifically, referring to fig. 2, in the embodiment shown in the drawing, the third material guiding plate 233 is located right below the first material guiding plate 231, is also inclined from top to bottom to left, and faces the right end of the second material guiding plate 232, and the third material guiding plate 233 can receive the mixed material falling along the second material guiding plate 232 and can guide the mixed material to fall toward the first-stage screen 220.

Alternatively, the primary separating mechanism 200 includes four or more guide plates.

The number of the guide plates provided in the primary separating mechanism 200 is not limited in the present application, as long as the guide plates are arranged in a level manner and are inclined with respect to each other as in the case of the first guide plate 231 and the second guide plate 232.

Optionally, the primary separation mechanism 200 further comprises: the first-stage blanking plate 241 is arranged in the first-stage separation bin 210 and is positioned above the first-stage screen 220, and the first-stage blanking plate 241 extends towards the first-stage screen 220 in an inclined mode; the primary material baffle plate 242 is rotatably arranged in the primary separation bin 210 and is opposite to the primary material discharging plate 241; the mixed material can follow one-level flitch 241 and move towards one-level screen cloth 220 down, and on the motion route of mixed material was located to one-level striker plate 242, mixed material can promote one-level striker plate 242, make one-level striker plate 242 keep away from one-level flitch 241 down to mixed material passes through between from one-level striker plate 242 and one-level flitch 241 down.

Referring to fig. 2 and 4, in the illustrated embodiment, the first-stage blanking plate 241 is disposed below the material blocking plates (the first material blocking plate 231, the second material blocking plate 232, and the third material blocking plate 233), and one end of the first-stage blanking plate 241 is connected to the inner wall of the first-stage separation bin 210, and the other end extends toward the first-stage screen 220. The first-stage striker plate 242 is arranged above the other end of the first-stage blanking plate 241, and can prevent the mixed material from passing through the first-stage blanking plate 241.

Specifically, the mixed material falling along the striker plate can fall onto the one-level striker plate 241 and can move toward the one-level striker plate 242 along the one-level striker plate 241, and since the one-level striker plate 242 is blocked in front of the outlet of the one-level striker plate 241, the mixed material is to leave the one-level striker plate 241, and it is necessary to rotate the one-level striker plate 242 in a direction away from the one-level striker plate 241. Therefore, before the mixed material rolls off, the primary striker plate 242 needs to be pushed, so that an opening is formed between the primary blanking plate 241 and the primary striker plate 242. When the mixed material pushes the first-stage striker plate 242, the movement speed of the mixed material is slowed down.

By arranging the first-level blanking plate 241, the movement path of the mixed material can be further prolonged, the falling impact force of the mixed material is reduced, and the mixed material is guided to accurately fall onto the first-level screen 220.

Through setting up flitch 241 under one-level striker plate 242 hinders the mixing material and leaves one-level, can further reduce the velocity of motion of mixing material, reduce the impact force that the mixing material dropped.

Optionally, the first-stage blanking plate 241 includes an inclined segment 241a and a horizontal segment 241b, the inclined segment 241a extends obliquely from top to bottom toward the first-stage screen 220, one end of the horizontal segment 241b is connected to the inclined segment 241a, and the other end extends horizontally toward the outlet of the first-stage separation bin 210.

Referring specifically to fig. 4, in the illustrated embodiment, the first-stage material baffle 242 is disposed above the horizontal section 241b, which is beneficial for slowing the speed of the mixed material leaving the first-stage material dropping plate 241.

In order to facilitate the rotation of the primary striker plate 242, in an embodiment, referring to fig. 2 and fig. 4, two opposite V-shaped supporting frames 243 are disposed in the primary separation bin 210, a supporting rod 244 is connected to a side of the primary striker plate 242 away from the primary blanking plate 241, and two ends of the supporting rod 244 are disposed in one V-shaped supporting frame 243 respectively. The V-shaped support 243 can stably support the support rod 244, and the support rod 244 can rotate and move in the V-shaped support 243. When the mixed material pushes the first-stage striker plate 242, the support rod 244 can move in the V-shaped support frame 243, so that the first-stage striker plate 242 is far away from the first-stage blanking plate 241.

Optionally, for convenient manual maintenance, the back of the primary striker plate 242 away from the primary blanking plate 241 and not contacting the mixed material is provided with a push-pull rod 245. An operator can act on the primary striker plate 242 through the push-pull rod 245 to facilitate the mounting, dismounting or moving of the primary striker plate 242.

Optionally, a visual window 214 is provided on the primary separation bin 210, so that an operator can observe the falling or separation condition of the mixed materials in the primary separation bin 210.

In the embodiment shown in fig. 4, one of the viewing windows 214 faces the primary striker plate 242. When the viewing window 214 is in the open position, the operator can act on the primary striker plate 242 through the viewing window 214.

It should be noted that in the embodiment shown in fig. 1, the primary lifting mechanism 100 and the secondary lifting mechanism 300 are arranged side by side along the first direction, the inlet of the primary separation bin 210 is communicated with the lifting bin 110 of the primary lifting mechanism 100, and the outlet of the primary separation bin 210 is communicated with the lifting bin 310 of the secondary lifting mechanism 300. Therefore, the inlet of the primary separation bin 210 and the outlet of the primary separation bin 210 are spaced apart in the first direction in addition to being spaced apart in the up-down direction. For example, in the position state shown in fig. 4, the inlet of the primary separation bin 210 is disposed at the upper left, and the outlet of the primary separation bin 210 is disposed at the lower right.

To facilitate the mixed material passing through the primary screen 220 to enter the lifting bin 310 of the secondary lifting mechanism 300 directly through the outlet of the primary separation bin 210 near the outlet of the primary separation bin 210, optionally, a primary blanking plate 241 is extended along the first direction. For example, in the position state shown in fig. 4, one end of the primary blanking plate 241 is connected to the inner wall of the primary separation chamber 210, and the other end extends toward the outlet of the primary separation chamber 210 along the first direction. Thus, after the mixed material falls into the first-level blanking plate 241, the mixed material can approach the outlet of the first-level separation bin 210 along the first-level blanking plate 241.

Alternatively, the bottom of the primary separation bin 210 is provided with a slope, and the slope is inclined towards the outlet of the primary separation bin 210. When the mixed material passing through the primary screen 220 falls on the slope, it can slide toward the outlet of the primary separation silo 210 under the influence of its own weight.

As the mixed material separates, non-target material may accumulate on the primary screen 220. To avoid excessive accumulation of non-target materials and to avoid affecting the sifting out of the target materials, the first-stage screen 220 needs to be cleaned.

In order to facilitate the assembly and disassembly of the primary screen 220, in one embodiment, a mounting opening is formed on the primary separating compartment 210, and the primary screen 220 can enter and exit the primary separating compartment 210 through the mounting opening.

At this time, the primary screen 220 is detachably disposed in the primary separating compartment 210. When the cleaning is needed, the primary screen 220 is detached through the mounting opening, so that non-target materials accumulated on the primary screen 220 can be removed; after cleaning, the primary screen 220 is installed back into the primary separation chamber 210 through the installation opening.

The present application does not limit the specific connection manner of the primary screen 220 and the primary separating bin 210, for example, the primary screen 220 and the primary screen 220 may be connected by screw threads, or may be clamped or inserted.

Optionally, a supporting plate 212 is further disposed in the primary separation bin 210, and after the primary screen 220 enters the primary separation bin 210 through the mounting port, the supporting plate 212 can hold the primary screen 220.

It will be readily appreciated that the primary screen 220 is sized such that the position of the primary screen 220 within the primary separation chamber 210 is limited to avoid the impact forces displacing the primary screen 220 as the mixing material falls onto the primary screen 220.

Therefore, the supporting plate 212 is arranged to support the first-stage screen 220, and the stability of the first-stage screen 220 can be effectively improved.

In the embodiment shown in fig. 2 and 3, a support plate 212 is disposed on each of the left wall and the right wall of the primary separation chamber 210, and the two support plates 212 are disposed opposite to each other and can support the left and right sides of the primary screen 220. If necessary, a supporting plate 212 can be disposed on the inner wall of the primary separation chamber 210 facing the installation opening.

Alternatively, the primary screen 220 includes a frame portion 221 and a cover portion 222, the cover portion 222 is disposed on one side of the frame portion 221, the frame portion 221 can enter the primary separation chamber 210 through the mounting port, and the cover portion 222 cannot enter the primary separation chamber 210 through the mounting port.

The frame portion 221 is provided with mesh wires, and the mesh wires are interwoven to form meshes. Small particle materials in the mixed materials can pass through the meshes, and large particle materials in the mixed materials can not pass through the meshes. The frame part 221 is similar to an open slot and can load materials which do not pass through the meshes; the side plates around the frame 221 can prevent the materials which do not pass through the meshes from falling off from the edge of the first-stage screen 220.

Since the cover 222 cannot enter the primary separation chamber 210, the cover 222 is located outside the primary separation chamber 210 during the separation process. When the primary screen 220 needs to be cleaned, an operator can pull out the primary screen 220 from the mounting opening through the cover 222.

Optionally, after the frame portion 221 enters the primary separation bin 210 through the mounting opening, the cover portion 222 can close the mounting opening, so as to prevent the mixed material from overflowing from the mounting opening.

Optionally, the primary separation chamber 210 is externally provided with a recovery tank 213, and the recovery tank 213 is provided below the installation opening.

It will be readily appreciated that some target material may not pass through the primary screen 220 or that non-target material may continue to build up on the primary screen 220, resulting in the target material failing to pass through the primary screen 220. For this reason, when cleaning the primary screen 220, the target material may exist on the primary screen 220. The target material is selected and placed in the recovery tank 213 to facilitate the collection of the target material.

Optionally, the recycling bin 213 communicates with the primary separation bin 210 so that the selected target material can be actively returned to the primary separation bin 210.

Optionally, the recycling bin 213 is provided with a mesh. Taking out the primary screen 220 from the mounting port, and shaking the primary screen 220 above the recovery tank 213 so that part of the mixed material on the primary screen 220 passes through the primary screen 220 and falls onto the recovery tank 213; because the recycling bin 213 is provided with the sieve holes through which the target materials can pass, the target materials falling onto the recycling bin 213 can enter the recycling bin 213 through the sieve holes.

Optionally, the lifting separation device further comprises a secondary separation mechanism 400 for receiving the mixed material conveyed by the secondary lifting mechanism 300; the secondary separation mechanism 400 includes: the second-stage separation bin 410 is communicated with the fourth station and the material receiving equipment; and the secondary screen 420 is arranged in the secondary separation bin 410 and used for screening out large-particle materials in the mixed materials.

The mixed material conveyed by the secondary lifting mechanism 300 is purified by the primary separation of the primary separation mechanism 200. Inevitably, some non-target materials with smaller particles can pass through the primary separation mechanism 200, or some non-target materials with larger particles pass through the primary separation mechanism 200 to the third station by other means. Therefore, a secondary separation mechanism 400 is arranged to further separate the mixed materials, and the separation effect is improved.

When the lifting separation device provided by the application is used for separating the shot, the material receiving equipment is the shot blasting device. Because the shot needs to obtain larger gravitational potential energy at a high position, the separation device is different from the primary separation mechanism 200, and the secondary separation bin 410 of the secondary separation mechanism is higher in arrangement position and does not need larger volume, as long as the separation device can accommodate the secondary screen 420 and can communicate the secondary lifting mechanism 300 with the material receiving equipment.

In the embodiment shown in fig. 5, the secondary separation silo 410 comprises an input silo 410a and an output silo 410b, the input silo 410a being arranged on the right for communication with the secondary lifting mechanism 300 and the output silo 410b being arranged on the left for communication with the material receiving apparatus.

Optionally, the secondary separation mechanism 400 further comprises: the secondary blanking plate 431 is arranged in the secondary separation bin 410 and is positioned above the secondary screen 420, and the secondary blanking plate 431 extends towards the secondary screen 420 in an inclined mode; a secondary striker plate 432 rotatably disposed in the secondary separation silo 410 and disposed opposite to the secondary blanking plate 431; the mixed material can move towards the second grade screen 420 along the second grade blanking plate 431, the second grade striker plate 432 is arranged on the moving route of the mixed material, and the mixed material can push the second grade striker plate 432 to enable the second grade striker plate 432 to be far away from the second grade blanking plate 431, so that the mixed material can pass through the second grade striker plate 432 and the second grade blanking plate 431.

The purpose and the arrangement manner of the second-stage blanking plate 431 and the second-stage striker plate 432 are similar to those of the first-stage blanking plate 241 and the first-stage striker plate 242, and are not described herein again.

Limited by the inlet of the secondary separation silo 410, the position of the secondary screen 420, and the outlet of the secondary separation silo 410, in the embodiment shown in fig. 5, the secondary blanking plate 431 is located right below the inlet of the secondary separation mechanism 400, and the right end of the secondary blanking plate 431 is connected to the right wall of the input silo 410a, and the left end of the secondary blanking plate 431 penetrates into the output silo 410b and points to the downward secondary screen 420. The mixed material transferred through the secondary lifting mechanism 300 passes through the inlet of the secondary separation silo 410, falls onto the secondary blanking plate 431, and then enters the output silo 410b along the secondary blanking plate 431 and moves toward the secondary screen 420. Because the secondary striker plate 432 can prevent the mixed material from leaving the secondary blanking plate 431, the mixed material is expected to pass through the secondary blanking plate 431, the secondary striker plate 432 needs to be pushed open first, and the movement speed of the mixed material can be slowed down.

Optionally, an air pipe 411 is arranged on the secondary separation bin 410, and the air pipe 411 is arranged below the secondary blanking plate 431 and is opposite to the discharge end of the secondary blanking plate 431; so that the air pipe 411 has negative pressure inside, and the air pipe 411 can draw out small-mass materials in the mixed materials.

It is readily appreciated that small particles of non-target material readily pass through the primary screen 220. Since the mass of the non-target materials is small, the small-mass materials are greatly influenced by air resistance in the process that the mixed materials fall through the secondary blanking plate 431, the falling speed is low, and the mixed materials are easy to float in the secondary separation bin 410. The air pipe 41 is used for exhausting air in the secondary separation bin 410, so that non-target materials with low quality can be easily extracted.

Of course, the negative pressure intensity in the air pipe 411 needs to be set according to the quality of the target material, so as to prevent the air pipe 411 from having too large adsorption force and sucking out the target material.

In the embodiment shown in fig. 5, the air duct 411 is communicated with the input bin 410a, and an inlet of the air duct 411 is opposite to a discharge end of the secondary blanking plate 431. After the mixed material leaves the second-stage blanking plate 431, the mixed material falls to the second-stage screen 420, and in the process of falling of the mixed material, the air pipe 411 can adsorb the mixed material.

Optionally, the opening of the air duct 411 is adjustable.

Optionally, the secondary separation mechanism 400 further comprises a material returning bin 440 disposed below the secondary blanking plate 431 and communicating the secondary separation bin 410 and the primary separation bin 210.

In the process of secondary separation of the mixed materials, some materials may drop into the material returning bin 440 by mistake, and target materials may exist in the materials, so that the materials return to the primary separation bin 210 through the material returning bin 440, which is beneficial to determining whether the target materials exist. If the target material exists, the target material can pass through the primary separation again and return to the secondary separation bin 410.

When the air pipe 411 is disposed on the secondary separation bin 410, if the adsorption force of the air pipe 411 is too large, the target material may move toward the air pipe 411 during the falling process, and although the target material does not enter the air pipe 411, the target material may deviate from the secondary screen 420. For this purpose, the material returning bin 440 is used to receive the material deviated from the secondary screen 420 and return the material to the primary separating bin 210, which is favorable for the utilization of the target material.

Optionally, an auxiliary plate 412 is further disposed in the secondary separation bin 410, and the auxiliary plate 412 is disposed below the secondary blanking plate 431 and is inclined toward the secondary blanking plate 431.

For example, in the embodiment shown in fig. 5, the secondary blanking plate 431 is inclined from top to bottom to the left, the auxiliary plate 412 is inclined from top to bottom to the right, a narrow channel is formed between the left end of the secondary blanking plate 431 and the left end of the auxiliary plate 412, and the air duct 411 faces the narrow channel. Therefore, the adsorption of the air pipe 411 is not hindered, and a large amount of mixed materials can be prevented from being mistakenly fed into the material returning bin 440.

Optionally, the feed back bin 440 is further provided with: an outflow port 441 communicated with the primary separation chamber 210; the overflow port 442 is communicated with the secondary separation bin 410 below the secondary screen 420. When too much mixed material passes through the secondary screen 420 and is accumulated in the secondary separation bin 410, the mixed material close to the overflow port 442 can enter the material return bin 440 through the overflow port 442 and then return to the primary separation bin 210 through the flow outlet 441, so that the secondary screen 420 is prevented from being blocked.

Optionally, a partition plate 413 is further disposed in the feed back bin 440. The partition plate 413 partitions the outflow port 441 and the mixed material outlet communicated with the primary separation silo 210.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
