Description

Technical Field

[0001] This utility model relates to the field of abrasive sorting technology, and in particular to a high-efficiency abrasive sorting device. Background Technology

[0002] Abrasives are sharp, hard materials used to grind the surfaces of softer materials. Abrasives are broadly classified into natural and synthetic abrasives. They are also classified by hardness into superhard and ordinary abrasives.

[0003] Existing abrasives require screening and sorting during the processing and production process.

[0004] Chinese Patent No. CN213319655U discloses an abrasive screening mechanism for a shot blasting machine, comprising a base plate, with upwardly extending and parallel support rods fixedly connected to the top surface of the base plate, a material trough fixedly connected to the top of the support rods, a control valve installed in the middle of the bottom surface of the material trough, a recessed plate connected to the middle of the support rods, and upwardly extending long rods connected to both sides of the top surface of the recessed plate, with a limit block sleeved above the long rods, the limit block fixedly connected to the side of the screening module, a frame connected to the right side of the recessed plate, a transmission device installed on the side of the frame, and a motor installed on the left side of the transmission device.

[0005] The aforementioned abrasive screening mechanism, through the design of a power transmission device and in conjunction with the screening module, allows the abrasive to be directly fed into the trough during screening operations, and the abrasive falls onto the screening module under the action of gravity.

[0006] However, in actual use, when too many particles are intercepted by the screening mesh or when the mesh needs to be cleared, the mesh needs to be removed for operation, which is time-consuming and laborious.

[0007] Therefore, a high-efficiency abrasive sorting device is proposed. Utility Model Content

[0011] The screening cylinder includes a tubular screen, both ends of which are fixedly connected to an annular track disc. A conical feed nozzle is fixedly installed on one side of one of the annular track discs, and a sealing plate is fixedly installed on one side of the other annular track disc.

[0012] The top of the base is rotatably mounted with a limiting roller via a support seat, and the annular track disk is rolled on the limiting roller.

[0016] In an efficient abrasive sorting device according to the present invention, a plurality of support rods are fixedly connected between two annular track disks, and the support rods are located on the outside of the tubular screen.

[0017] In a high-efficiency abrasive sorting device according to the present invention, the dust cover is a transparent acrylic sheet.

[0018] This utility model has at least the following beneficial effects:

[0019] This utility model can quickly sort abrasives by setting a screening cylinder in conjunction with a drive mechanism. When it is necessary to discharge large abrasive particles accumulated inside the screening cylinder, simply reverse the screening cylinder, and the large abrasive particles can be discharged from the conical feed nozzle along with the spiral plate. The operation is simple and quick.

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Please refer to Figures 1 to 3 As shown in the figure, this embodiment provides an efficient abrasive sorting device, including a base 1, a sieve cylinder for sorting abrasive is rotatably connected to the top of the base 1, a spiral plate 8 is fixedly welded to the inner wall of the sieve cylinder, the sieve cylinder includes a tubular screen 3, both ends of the tubular screen 3 are fixedly connected to an annular track disk 2, a conical feed nozzle 7 is fixedly installed on one side of one annular track disk 2, a sealing plate is fixedly installed on one side of the other annular track disk 2, a drive mechanism for driving the sieve cylinder to rotate is fixedly installed on the base 1, the drive mechanism includes a motor 11, the motor 11 is fixedly installed on the base 1, a gear disk 9 is fixedly installed on the outer wall of the conical feed nozzle 7, and the gear disk 9 meshes with a gear 12;

[0030] The top of the base 1 is rotatably mounted with a limiting roller 10 via a support seat, and the annular track disk 2 is rolled on the limiting roller 10.

[0031] By adopting the above technical solution, when using the equipment, the abrasive to be sorted is fed into the tubular screen 3 through the conical feed nozzle 7. The motor 11 is started, which drives the screening cylinder to rotate clockwise through the gear 12 and the gear disc 9. Abrasive with a diameter smaller than the filter holes of the tubular screen 3 is screened out by the tubular screen 3. When it is necessary to discharge large abrasive particles accumulated in the screening cylinder, it is only necessary to control the shaft of the motor 11 to reverse, which in turn drives the screening cylinder to reverse. The large abrasive particles can then be discharged from the conical feed nozzle 7 along with the spiral plate 8. The operation is simple and quick.

[0032] In this embodiment, a dust cover 6 is fixedly installed on the top of the base 1 by the mounting plate 601, the tubular screen 3 is located inside the dust cover 6, and the bottom of the dust cover 6 is provided with a discharge port 602. The dust cover 6 can effectively prevent dust from flying around during the screening of abrasive materials.

[0033] In this embodiment, an air knife 5 is fixedly installed on the top of the dust cover 6. The air outlet of the air knife 5 is located inside the dust cover 6, and the air outlet of the air knife 5 faces the outer wall of the tubular screen 3. When the tubular screen 3 is blocked, the air inlet of the air knife 5 is connected to the compressor, and the high-pressure gas blown out by the air knife 5 can quickly clear the blockage of the rotating tubular screen 3.

[0034] In this embodiment, a number of support rods 4 are fixedly connected between the two annular track disks 2. The support rods 4 are located on the outside of the tubular screen 3. The support rods 4 can effectively support the tubular screen 3 and improve the support strength of the entire screening cylinder.

[0035] In this embodiment, the dust cover 6 is made of transparent acrylic sheet to facilitate observation of the operating status of the screening cylinder, so that blockages in the tubular screen 3 can be quickly detected.

[0036] The specific workflow of the high-efficiency abrasive sorting device in this embodiment is as follows:

[0037] 1. Preparation stage:

[0038] Prepare the abrasive materials that need to be sorted.

[0039] Ensure that the power supply connection of equipment such as motor 11 is normal.

[0040] If you need to use the air knife 5 to clear blockages, connect the air inlet of the air knife 5 to the compressor.

[0041] 2. Feeding:

[0042] The abrasive is fed into the tubular screen 3 through the conical feed nozzle 7.

[0043] 3. Start the screening process:

[0044] Start the motor 11. The shaft of the motor 11 meshes with the gear 9 through the gear 12, driving the screening cylinder (including the tubular screen 3 and the annular track disk 2) to rotate clockwise.

[0045] The rotation of the screening cylinder causes the abrasive to be screened inside the tubular screen 3, and the abrasive with a diameter smaller than the filter holes of the tubular screen 3 is screened out.

[0046] 4. Collect fine abrasive:

[0047] The sieved fine abrasive is collected through the discharge port 602 at the bottom of the dust cover 6.

[0048] 5. Observation and Clearing Blockages:

[0049] Operators can observe the operating status of the screening cylinder and the blockage of the tubular screen 3 in real time by looking inside the dust cover 6 (transparent acrylic plate).

[0050] If the tubular screen 3 is found to be clogged, the air knife 5 can be activated. The high-pressure gas blown out by the air knife 5 can quickly clear the blockage of the rotating tubular screen 3.

[0051] 6. Discharge of large abrasive particles:

[0052] When it is necessary to discharge large particles of abrasive material accumulated in the screening cylinder, the shaft of the control motor 11 is reversed, which drives the screening cylinder to reverse.

[0053] Large abrasive particles are discharged from the conical feed nozzle 7 along with the spiral plate 8.

[0054] 7. Closure and Cleanup:

[0055] After screening is complete, turn off motor 11 and air knife 5 (if they have been used).

[0056] Perform necessary cleaning and maintenance on the equipment in preparation for its next use.

[0057] Throughout the entire workflow, the dust cover 6 effectively prevents dust from scattering everywhere, ensuring a clean working environment. At the same time, the dust cover 6, made of transparent acrylic sheet, allows operators to easily observe the operating status of the screening cylinder and the blockage of the tubular screen 3, ensuring the smooth progress of the screening operation.
