Description

Technical Field

[0001] This utility model relates to the field of screen technology, and in particular to a screen for a vertical centrifuge. Background Technology

[0002] Screens differ from ordinary mesh products; they are mesh products with strictly defined mesh sizes and functions for grading and screening particles, conforming to industry, institutional, and standard approvals. Screens are used across a wide range of fields, including industry, science and technology, agriculture, and national defense, from cutting-edge technology and high-tech industries to everyday life, including clothing, food, housing, and culture, developing in tandem with the national economy. Traditional screens are made by weaving horizontal and vertical metal wires together, creating mesh openings between the wires to sift materials.

[0003] Existing centrifuge screens are prone to damage during use if the material is unevenly fed or if the material accumulates, resulting in larger mesh openings and ultimately failing to achieve the desired screening effect. Therefore, a vertical centrifuge screen has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a screen for a vertical centrifuge, which solves the problem mentioned in the background art that uneven material feeding or material accumulation can easily damage the screen structure, causing the mesh to become larger and ultimately failing to achieve the desired screening effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen for a vertical centrifuge, comprising a screen outer frame, four connecting blocks fixedly connected to both sides of the screen outer frame, a sliding groove fixedly opened inside the connecting blocks, a tension adjustment mechanism slidably connected inside the sliding groove, four small hydraulic rods fixedly connected to the top of the screen outer frame, a motor housing fixedly connected to the top of one of the small hydraulic rods, an anti-clogging mechanism installed inside the motor housing, the tension adjustment mechanism comprising a connecting plate slidably connected inside the sliding groove, electric push rods fixedly connected to both sides of the connecting plate, and a battery electrically connected to one side of the electric push rod via a power cord; the anti-clogging mechanism comprises a drive motor installed inside the motor housing, a lead screw fixedly connected to the output end of the drive motor, a brush plate threadedly connected to the surface of the lead screw, and several brush heads fixedly connected to the bottom of the brush plate.

[0006] As a further embodiment of this utility model, a number of transverse metal wires are installed on one side of the inner side of the screen outer frame, and a number of longitudinal metal wires are installed on the other side of the inner side of the screen outer frame. The arrangement of the transverse and longitudinal metal wires serves to screen the materials.

[0007] As a further embodiment of this utility model, one side of the transverse metal wire and the longitudinal metal wire are fixedly connected to the surface of the connecting plate. The transverse metal wire and the longitudinal metal wire are interwoven into a mesh structure. The connecting plate serves to fix the transverse metal wire and the longitudinal metal wire.

[0008] As a further embodiment of this utility model, a limiting hole is provided on one side of the brush plate, and a limiting rod is slidably connected inside the limiting hole. The limiting rod serves to limit the movement of the brush plate.

[0009] As a further embodiment of this utility model, connecting parts are fixedly connected to both sides of the limiting rod. The connecting parts are fixedly connected to the top of the small hydraulic rod. The small hydraulic rod is used to drive the brush head to move up and down.

[0010] As a further embodiment of this utility model, an extension block is rotatably connected to the end of the lead screw, and the extension block is fixedly connected to the top of the small hydraulic rod. The extension block serves to support the lead screw.

[0011] As a further embodiment of this utility model, a fixing plate is fixedly connected to one side of the connecting block, and the electric push rod is installed on the surface of the fixing plate. The fixing plate serves to fix the electric push rod.

[0012] This utility model provides a screen for a vertical centrifuge, which has the following advantages:

[0013] 1. The screen used in this vertical centrifuge has a tension adjustment mechanism. When the power is turned on, the electric push rods on both sides are activated. The extension and retraction of the electric push rods can drive the connecting plate at the end to slide inside the slide groove. This stretches the several horizontal and vertical metal wires connected to one side of the connecting plate, thereby achieving the effect of adjusting the tension of the screen and preventing the mesh from becoming larger and affecting the screening effect of the screen during long-term use.

[0014] 2. The screen used in this vertical centrifuge features an anti-clogging mechanism. During operation, the drive motor inside the motor housing is activated, causing the lead screw at the end to rotate. This causes the brush plate, which is threaded onto the lead screw, to move left and right along the lead screw. At this time, a small hydraulic rod is used to press several brush heads at the bottom of the brush plate against the surfaces of the transverse and longitudinal metal wires. The reciprocating motion of the brush heads then cleans the material clogging the mesh, thus achieving the effect of preventing screen clogging and avoiding disruption to the normal use of the screen.

The tension adjustment mechanism 3 includes a connecting plate 301 slidably connected inside the slide groove. Electric push rods 302 are fixedly connected to both sides of the connecting plate 301. One side of the electric push rod 302 is electrically connected to a battery 303 through a power line. The anti-blocking mechanism 6 includes a drive motor 601 installed inside the motor box 5. A lead screw 602 is fixedly connected to the output end of the drive motor 601. A brush plate 603 is threadedly connected to the surface of the lead screw 602. Several brush heads 604 are fixedly connected to the bottom of the brush plate 603.

[0022] Several transverse metal wires 7 are installed on one side of the inner side of the screen outer frame 1, and several longitudinal metal wires 8 are installed on the other side of the inner side of the screen outer frame 1. The arrangement of the transverse metal wires 7 and the longitudinal metal wires 8 plays a role in screening materials.

[0023] One side of the transverse metal wire 7 and the longitudinal metal wire 8 are fixedly connected to the surface of the connecting plate 301. The transverse metal wire 7 and the longitudinal metal wire 8 are interwoven into a mesh structure. The connecting plate 301 serves to fix the transverse metal wire 7 and the longitudinal metal wire 8.

[0024] A limiting hole is provided on one side of the brush plate 603, and a limiting rod 9 is slidably connected inside the limiting hole. The limiting rod 9 serves to limit the position of the brush plate 603.

[0025] Both sides of the limiting rod 9 are fixedly connected to the connecting parts 10, which are fixedly connected to the top of the small hydraulic rod 4. The small hydraulic rod 4 is used to drive the brush head 604 to rise and fall.

The extension and retraction of the electric push rods 302 can drive the connecting plate 301 at the end to slide inside the groove, so that the several horizontal metal wires 7 and vertical metal wires 8 connected to one side of the connecting plate 301 are stretched.

[0030] The second step: When using the device, the drive motor 601 inside the motor box 5 can be started. The drive motor 601 drives the lead screw 602 at the end to rotate, which causes the brush plate 603 threaded on the surface of the lead screw 602 to move left and right on the lead screw 602. At this time, the small hydraulic rod 4 can be used to press the several brush heads 604 at the bottom of the brush plate 603 against the surface of the transverse metal wire 7 and the longitudinal metal wire 8. Then, the reciprocating motion of the brush heads 604 is used to clean the material blocked in the mesh.
