Description

Technical Field

[0001] This invention relates to the field of granular material screening technology, and more specifically to a parabolic granular material separation and screening device. Background Technology

[0002] Granular material separation and screening is an industrial process used to classify and separate mixed granular materials according to their size or other characteristics. This process is commonly used in production processes in building materials, mineral processing, food processing, chemicals, and other industries. Granular material separation and screening typically utilizes one or more screening devices, such as vibrating screens, cyclone screens, and drum screens. In existing technologies, common screening methods generally follow a large-to-small-particle principle when screening granular materials, i.e., screening large particles. However, in this process, small particles inevitably enter the space where large particles are collected and cannot pass through the screen below due to the obstruction of the large particles, resulting in additional screening steps after screening. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems existing in the above-mentioned parabolic particle separation and screening devices, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a parabolic particle separation and screening device, which aims to solve the problem that small particles inevitably enter the large particle collection space and cannot pass through the screen below due to the obstruction of the large particles, resulting in additional screening steps after screening.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a parabolic particle separation and screening device, which includes a screening tank and a spacer fixedly connected to the inner cavity of the screening tank, wherein the screening tank is provided with screening components and a resetting component.

[0007] The screening component includes a drive device installed inside the screening tank. A movable plate is threadedly connected to the outside of the drive device. The movable plate is slidably connected to the inside of the upper side of the tray. The tray is fitted onto the outside of the drive device. A rotating disk is fixedly connected to the outer wall of the drive device. Two fixed rods are fixedly connected to the top of the rotating disk. A through hole is opened inside the tray. A column is slidably connected to each of the two through holes. The two columns are fixedly connected to the bottom of the same storage basket. The bottom of the two columns overlaps with the top of the two fixed rods respectively. A sleeve is fixedly connected inside the storage basket. The storage basket is fitted onto the outside of the spacer. Both the storage basket and the sleeve are fitted onto the outside of the drive device. A storage assembly is also provided inside the screening tank.

[0008] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, the driving device consists of a servo motor and a lead screw, and the lower side of the outer wall of the lead screw is not provided with an external thread. The receiving component includes a first screen fixedly connected inside the screening tank, the first screen being sleeved on the outer wall of the receiving basket, and a second screen fixedly connected inside the screening tank. The aperture of the holes on the outer surfaces of the receiving basket, the first screen, and the second screen gradually decreases from the inside to the outside, thereby screening the particle material step by step.

[0009] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, a first receiving tray is slidably connected to one side of the screening tank, and a second receiving tray is slidably connected to one side of the screening tank. The bottom end of the first receiving tray and the top end of the second receiving tray overlap each other, which facilitates the handling of the screened particles.

[0010] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, a first receiving groove is provided at the top of the first receiving tray, a second receiving groove is provided at the top of the second receiving tray, the cavity between the first screen and the second screen is connected to the first receiving groove, and the cavity between the second screen and the inner wall of the screening tank is connected to the second receiving groove, so as to receive the screened particles.

[0011] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, two fixed cylinders are fixedly connected to the inner top of the first receiving tray. A first pressure spring is fixedly connected to the inner bottom of each of the two fixed cylinders. The two first pressure springs are respectively sleeved on the outer surface of the two limiting rods, and the top of the first pressure springs overlaps with the outer surface of the limiting rods. The fixed cylinders are sleeved on the outer wall of the limiting rods. The tops of the two limiting rods are fixedly connected to the top of the same third screen. The third screen is slidably connected inside the first receiving tray to further screen the particles inside the first receiving tray.

[0012] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, the resetting component includes two electric push rods fixedly connected to the inner cavity of the screening tank. The top ends of the two electric push rods overlap with the bottom end of the same tray. The electric push rods and the driving device are both electrically connected to an external control device to raise the height of the tray.

[0013] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, the top of the tray is provided with a movable groove, the bottom of the storage basket is fixedly connected with an extrusion plate, the inside of the tray is slidably connected with a pressure plate, and the lower side of the extrusion plate passes through the movable groove and presses against the inclined part of the pressure plate to adjust the position of the pressure plate.

[0014] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, two first tension springs are fixedly connected to the side of the pressure plate away from the moving plate, and the other ends of the two first tension springs are fixedly connected to the inner side wall of the tray. Two second pressure springs are fixedly connected to the side of the pressure plate near the moving plate, and the other ends of the two second pressure springs are fixedly connected to the side of the moving block near the pressure plate to pull the moving block.

[0015] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, a movable groove is provided at the bottom of the inner side of the tray, a second tension spring is fixedly connected to the bottom of the inner side of the movable groove, a locking rod is fixedly connected to the top of the second tension spring, and the locking rod is slidably connected in the movable groove to limit the locking rod.

[0016] In a preferred embodiment of the parabolic particle separation and screening device of the present invention, four magnetic blocks are fixedly connected to the top of the rotating disk and the bottom of the two locking rods, and adjacent magnetic blocks repel each other. A locking groove is provided at the bottom of the moving plate, and the locking groove is connected to the moving groove. The locking rod is slidably connected in the locking groove to lock the moving plate.

[0017] In summary, the present invention has at least one of the following beneficial effects:

[0018] In this invention, a driving device moves a tray and a storage basket above it downwards. When the tray connects with the fixed rod above the rotating disk through the through hole, the tray stops moving downwards and begins to move in a circular motion. At this time, the storage basket is completely detached from the spacer. After the storage basket rotates, the granules inside the storage basket are thrown out by centrifugal force, which facilitates the adjustment of the position of the storage basket so that it starts to rotate after reaching the designated position and the granules are screened by the storage component. After moving upwards, the storage basket stops rotating to be used for feeding granules.

[0019] This invention uses a first screen and a second screen to screen granules of different sizes. The granules of different sizes are then fed into a first storage tray and a second storage tray, respectively, through a first storage trough and a second storage tray. The granules entering the first storage tray are further screened through a third screen. This facilitates the differentiation and separate storage of granules of different sizes. At the same time, smaller granules entering the first storage tray can be further screened to reduce subsequent screening steps.

[0020] In this invention, a magnetic block pushes a locking rod, causing the locking rod to enter the locking groove. After the locking rod enters the groove, the moving plate is in contact with the lead screw. After the pressing plate is released from the pressure plate, the moving plate is pulled by the first tension spring, moving the moving plate away from the lead screw. This facilitates quick adjustment of the position of the moving plate, which in turn helps control the lead screw's adjustment of the tray position. After the lead screw rotates, the moving plate can smoothly return from the unthreaded area to the threaded area. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention discloses a parabolic particle separation and screening device.

[0033] This invention provides, for example Figure 1-7 The parabolic particle separation and screening device shown includes a screening tank 1 and a spacer 2 fixedly connected to the inner cavity of the screening tank 1. The screening tank 1 is provided with a screening component 3 and a reset component 5.

[0034] The screening component 3 includes a drive device 31 installed inside the screening tank 1. A movable plate 32 is threadedly connected to the outside of the drive device 31. The movable plate 32 is slidably connected to the upper inside of the tray 33. The tray 33 is fitted onto the outside of the drive device 31. A rotating disk 34 is fixedly connected to the outer wall of the drive device 31. Two fixed rods are fixedly connected to the top of the rotating disk 34. A through hole 36 is opened inside the tray 33. A column 35 is slidably connected to each of the two through holes 36. The two columns 35 are fixedly connected to the bottom of the same storage basket 37. The bottom of the two columns 35 overlaps with the top of the two fixed rods respectively. A sleeve 38 is fixedly connected inside the storage basket 37. The storage basket 37 is fitted onto the outside of the spacer 2. Both the storage basket 37 and the sleeve 38 are fitted onto the outside of the drive device 31. A storage assembly 39 is also provided inside the screening tank 1.

[0035] The granules are poured from above the screening tank 1 into the collection basket 37. At this time, the granules inside the collection basket 37 are blocked by the spacer 2. Then, the servo motor inside the drive device 31 is started to drive the lead screw to rotate. Since the internal thread inside the moving plate 32 is engaged with the external thread on the surface of the lead screw, when the lead screw rotates, the moving plate 32 above the tray 33 will drive the tray 33 to move downward. The collection basket 37 and the granules inside it will follow the tray 33 downward until the two columns 35 below the collection basket 37 enter the tray 3. Inside the through hole 36 inside the tray 3, the fixing rod above the turntable on the outside of the screw will be inside the through hole 36 and support the two columns 35. Since the lower part of the screw is not provided with external threads, the screw will not be able to continue to drive the tray 33 to move downward. The fixing rod above the turntable 34 and the column 35 below the storage basket 37 are both inside the through hole 36 inside the tray 33. When the screw drives the turntable 34 to rotate, the storage basket 37 will also rotate and screen and collect the granules through the storage component 39.

[0036] In order to collect the sieved granules, such as Figure 1-3 As shown, the drive device 31 consists of a servo motor and a lead screw, and the lower side of the outer wall of the lead screw is not provided with an external thread. The storage component 39 includes a first screen 391 fixedly connected inside the screening tank 1. The first screen 391 is sleeved on the outer wall of the storage basket 37. A second screen 392 is fixedly connected inside the screening tank 1. The aperture of the holes on the outer surfaces of the storage basket 37, the first screen 391, and the second screen 392 gradually decreases from the inside to the outside. A first storage tray 393 is slidably connected to one side of the screening tank 1, and a second storage tray 394 is slidably connected to one side of the screening tank 1. The bottom end of the first storage tray 393 and the top end of the second storage tray 394 overlap each other. A first storage groove 395 is opened at the top end of the first storage tray 393, and a second storage groove 395 is opened at the top end of the second storage tray 394. The cavity between the first screen 391 and the second screen 392 in the groove 396 is connected to the first storage groove 395. The cavity between the second screen 392 and the inner wall of the screening tank 1 is connected to the second storage groove 396. Two fixed cylinders 397 are fixedly connected to the top of the inside of the first storage tray 393. The bottom of the inside of each of the two fixed cylinders 397 is fixedly connected to a first pressure spring 398. The two first pressure springs 398 are respectively sleeved on the outer surface of the two limiting rods 399, and the top of the first pressure spring 398 overlaps with the outer surface of the limiting rod 399. The fixed cylinders 397 are sleeved on the outer wall of the limiting rod 399. The top of the two limiting rods 399 is fixedly connected to the top of the same third screen 4. The third screen 4 is slidably connected inside the first storage tray 393.

[0037] Because the apertures of the outer sides of the storage basket 37, the first screen 391, and the second screen 392 gradually decrease from the inside out, when the storage basket 37 rotates, the granules inside will be thrown out by centrifugal force and pass through the first screen 391 and the second screen 392. Larger granules will be screened by the first screen 391, while smaller granules will pass through the second screen 392. The granules that reach between the first screen 391 and the second screen 392 will enter the first storage tray 393 through the first storage groove 395, while the granules that reach between the second screen 392 and the inner wall of the screening tank 1 will... The material will enter the second collection tray 394 through the second collection groove 396, while the granules entering the first collection groove 395 will be collected by the third screen 4 inside the first collection tray 393. After the third screen 4 is compressed, the limiting rod 399 above it moves inside the fixed cylinder 397 and is repeatedly shaken by the spring given by the first pressure spring 398. Finally, the smaller particles that have entered the first collection tray 393 are shaken into the second collection tray 394. Both the first collection tray 393 and the second collection tray 394 can be pulled out from one side of the screening tank 1.

[0038] Finally, in order to control the position of tray 33 and movable plate 32, such as Figure 4-7 As shown, the reset component 5 includes two electric push rods 51 fixedly connected to the inner cavity of the screening tank 1. The top ends of the two electric push rods 51 overlap with the bottom end of the same tray 33. Both the electric push rods 51 and the drive device 31 are electrically connected to an external control device. The top end of the tray 33 has a movable groove 52. The bottom end of the storage basket 37 is fixedly connected to a pressing plate 53. A pressure plate 54 is slidably connected inside the tray 33. The lower side of the pressing plate 53 passes through the movable groove 52 and presses against the inclined part of the pressure plate 54. Two first tension springs 55 are fixedly connected to the side of the pressure plate 54 away from the movable plate 32. The other ends of the two first tension springs 55 are fixedly connected to the inner side wall of the tray 33. Two second pressure springs 56 are fixedly connected to the side of plate 54 near the moving plate 32. The other ends of the two second pressure springs 56 are fixedly connected to the side of the moving block near the pressure plate 54. A moving groove 57 is opened at the bottom of the inner side of the tray 33. A second tension spring 58 is fixedly connected to the bottom of the inner side of the moving groove 57. A locking rod 6 is fixedly connected to the top of the second tension spring 58. The locking rod 6 is slidably connected in the moving groove 57. Four magnetic blocks 8 are fixedly connected to the top of the rotating disk 34 and the bottom of the two locking rods 6. Adjacent magnetic blocks 8 repel each other. A locking groove 7 is opened at the bottom of the moving plate 32. The locking groove 7 is connected to the moving groove 57. The locking rod 6 is slidably connected in the locking groove 7.

[0039] When the reverse-start servo motor drives the lead screw to rotate, the two electric push rods 51 will push the tray 33 upward. As the fixed rod above the rotating disk 34 disengages from the through hole 36 inside the tray 33, the repulsive effect of the magnetic block 8 above the rotating disk 34 on the magnetic block 8 below the locking rod 6 disappears. This allows the locking rod 6 to be pulled out of the locking groove 7 below the moving plate 32 by the second tension spring 58 and fully enter the moving groove 57. At this time, the moving block will be pulled away from the lead screw by the first tension spring 55 inside the tray 33. When the pressing block issued by the storage basket 37 passes through the movable groove 52 above the tray 33 and presses the pressed block, the moving block will reconnect with the lead screw. During the rotation of the lead screw, the moving block will be slightly displaced by the second pressure spring 56, so that the moving plate 32 can be smoothly connected with the lead screw and move upward, so that the storage basket 37 is once again placed on the outside of the spacer 2.

[0040] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
