Description

Technical Field

[0001] This utility model relates to the field of high-frequency vibrating screen technology, and more specifically, to an anti-clogging high-frequency vibrating screen. Background Technology

[0002] The rational processing and utilization of ore resources is a crucial task. In the process of ore processing, mineral beneficiation is the key first step, which involves screening the ore using vibrating screens.

[0003] A search revealed a utility model patent with publication number CN222343446U, which discloses a high-frequency vibrating screening device. The device includes a screen box with movable rods at the four corners of the bottom of the screen box's inner cavity. A screen mesh is fitted onto the surface of each movable rod. When screening building materials, the materials are placed in the screen box, and a motor is activated. The motor drives a rotating rod to rotate, which in turn drives a cam to rotate. The cam causes the screen mesh to vibrate up and down. The movable rods move in conjunction with the screen mesh, and a connecting plate and spring move the screen mesh back and forth. The screen mesh then screens the building materials, which are discharged through the outlet. To clean and prevent clogging of the screen, a handle is moved, which in turn moves a sliding sleeve. A sliding rod moves in conjunction with the sliding sleeve, which in turn moves an electric push rod. The electric push rod then moves a pressure plate and a push rod. However, the aforementioned patent has the following shortcomings: the springs, connecting plates, and sliding rods are all located above the screen mesh in the screen box. When materials are placed into the screen box for screening, they easily adhere to the springs, connecting plates, and other parts, causing blockages. Furthermore, when the insert rod moves downwards to clear the screen holes, if the material blocking the holes is too large, the insert rod cannot allow the blocking material to pass through the screen holes and fall out, affecting the clearing effect. Therefore, we propose an anti-clogging high-frequency vibrating screen. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an anti-clogging high-frequency vibrating screen.

[0005] To solve the above problems, this utility model adopts the following technical solution: an anti-clogging high-frequency vibrating screen, including a support frame, a plurality of springs fixedly connected to the top surface of the support frame, two support plates fixedly connected to the top ends of the plurality of springs, a screen box fixedly connected between the two support plates, a discharge chute provided at one end of the screen box, a screen plate fixedly sleeved in the inner cavity of the screen box, a plurality of screen holes opened on the top surface of the screen plate, the top surface of the screen plate and the bottom surface of the inner cavity of the discharge chute being in contact, a mounting base fixedly connected in the inner cavity of the screen box, a high-frequency vibrating motor fixedly mounted on the top surface of the mounting base, a blockage clearing mechanism provided in the inner cavity of the screen box, a plurality of sliding rods fixedly connected to the bottom surface of the support plate, and the bottom ends of the plurality of sliding rods being movably sleeved with the support frame respectively.

[0006] As a preferred embodiment of this utility model, the unblocking mechanism includes a reciprocating lead screw rotatably connected to the inner cavity of the screen box and a servo motor fixedly installed at the end of the screen box. The output shaft of the servo motor is connected to the end of the reciprocating lead screw. A movable seat is threaded onto the outer side of the reciprocating lead screw. Support columns are fixedly connected to the top surfaces of both ends of the movable seat. A mounting box is fixedly connected to the top of the two support columns. Multiple electric push rods are fixedly installed in the inner cavity of the mounting box. The output ends of the multiple electric push rods extend to the top of the mounting box and are fixedly connected to the inserts. The positions of the inserts are adapted to the positions of the screen holes. The two ends of the movable seat are respectively in contact with the inner wall of the screen box.

[0007] In a preferred embodiment of this utility model, a mounting plate is fixedly connected to the side of the support frame, and a control panel is fixedly mounted on the side of the mounting plate.

[0008] As a preferred embodiment of this utility model, a V-shaped baffle is provided in the inner cavity of the sieve box and above the reciprocating lead screw.

[0009] In a preferred embodiment of this utility model, the inner diameter of the sieve hole is equal to the outer diameter of the insert post.

[0010] As a preferred embodiment of this utility model, the bottom surface of the support frame is fixedly connected with multiple support legs.

[0011] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, the screen plate is directly fixedly sleeved in the inner cavity of the screen box, and the screen box is supported by the spring and support plate on the top surface of the support frame. When screening the ore, the screen box and screen plate are vibrated by a high-frequency vibration motor to screen the ore. At the same time, there are no other mechanisms above the screen plate in the inner cavity of the screen box, which avoids the material from clogging in the inner cavity of the screen box.

[0012] In this invention, when screening mineral materials using the screen holes on the screen plate, multiple inserts are moved intermittently by the threaded engagement between the reciprocating screw and the moving seat. When the inserts move to the bottom of the screen holes, the electric push rod drives the inserts to move up and down once, so that the inserts are inserted into the screen holes and push the mineral materials blocking the screen holes upward, thereby effectively clearing the screen holes on the screen plate. It has good practicality. Attached Figure Description

The bottom ends of the multiple sliding rods 19 are respectively movably sleeved with the support frame 1.

[0022] In this embodiment, the support plate 18 provides inclined support for the screen box 3, ensuring that the ore on the screen plate 4 can be moved by the vibration of the high-frequency vibration motor 8.

[0023] For details, please refer to Figure 3 and Figure 4 The unblocking mechanism 9 includes a reciprocating screw 10 rotatably connected to the inner cavity of the screen box 3 and a servo motor 11 fixedly installed at the end of the screen box 3. The output shaft of the servo motor 11 is connected to the end of the reciprocating screw 10. A movable seat 12 is threaded onto the outer side of the reciprocating screw 10. Support columns 13 are fixedly connected to the top surfaces of both ends of the movable seat 12. Mounting boxes 14 are fixedly connected to the top ends of the two support columns 13. Multiple electric push rods 15 are fixedly installed in the inner cavity of the mounting box 14. The output ends of the multiple electric push rods 15 extend to the top of the mounting box 14 and are fixedly connected to the inserts 16. The position of the inserts 16 is adapted to the position of the screen holes 5. The two ends of the movable seat 12 are respectively attached to the inner wall of the screen box 3.

[0024] In this embodiment, the inner wall of the sieve box 3 is used to limit the movement seat 12, so that the movement seat 12, the mounting box 14 and the insert 16 can only move along the axial direction of the reciprocating screw 10.

[0025] For details, please refer to Figure 1A mounting plate 21 is fixedly connected to the side of the support frame 1, and a control panel 22 is fixedly installed on the side of the mounting plate 21.

[0026] In this embodiment, the control panel 22 is electrically connected to the high-frequency vibration motor 8, the servo motor 11 and the electric push rod 15 respectively, and the high-frequency vibration motor 8, the servo motor 11 and the electric push rod 15 are controlled through the control panel 22.

[0027] For details, please refer to Figure 3 and Figure 4 A V-shaped baffle 17 is provided in the inner cavity of the screen box 3 and above the reciprocating screw 10.

[0028] In this embodiment, a V-shaped baffle 17 is used to protect the top of the reciprocating screw 10 to prevent falling ore from contacting the reciprocating screw 10.

[0029] For details, please refer to Figure 2 and Figure 4 The inner diameter of the sieve hole 5 is equal to the outer diameter of the insert post 16.

[0030] In this embodiment, the insert 16 is ensured to be inserted into the screen hole 5 in order to clear the ore material that is blocking the screen hole 5.

[0031] For details, please refer to Figure 1 Multiple support legs 20 are fixedly connected to the bottom surface of the support frame 1.

[0032] In this embodiment, multiple support legs 20 are used to support the support frame 1.

[0033] Working principle: In use, firstly, the high-frequency vibration motor 8 is started to drive the mounting base 7 and the screen box 3 to vibrate at high frequency. Then, the ore to be screened is placed on the screen plate 4 inside the screen box 3. The vibration of the screen box 3 drives the ore on the screen plate 4 to move, causing the ore that meets the conditions to fall through the screen holes 5, while the ore that does not meet the conditions is discharged from the discharge chute 6 at the end of the screen box 3. Then, the servo motor 11 is started to drive the reciprocating screw 10 to rotate intermittently. The threaded engagement between the reciprocating screw 10 and the moving base 12 drives the moving base to rotate. 12. The support column 13, mounting box 14, electric push rod 15, and insert column 16 move intermittently. The distance that the insert column 16 moves intermittently is equal to the distance between two adjacent screen holes 5 along the length of the screen plate 4, so that the insert column 16 moves intermittently to directly below the screen hole 5. Finally, when the insert column 16 moves to the bottom of the screen hole 5, the electric push rod 15 drives the insert column 16 to move up and down once, so that the insert column 16 is inserted into the screen hole 5 and pushes the blocked ore in the screen hole 5 upward, thereby clearing the blockage of the screen hole 5 on the screen plate 4.
