Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a particle screening device. Background Technology

[0002] In the production of gallium oxide (Ga2O3) single crystals, the particle size sieving of raw materials is crucial. Especially in the preparation of high-quality gallium oxide single crystals, the uniformity of the raw material particle size directly affects the quality and performance of the crystal. To ensure effective sieving, a suitable sieving device needs to be designed to classify the raw materials according to different particle sizes.

[0003] In the existing technology, when screening gallium oxide single crystal raw materials, most traditional screening devices use vibrating screens. However, traditional screening devices operate in a straight line, and the raw materials fall down along the surface of the screening screen for screening. However, when the raw materials accumulate on the surface of the screening screen, they become separated from each other, thus affecting the screening efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a particle screening device.

[0005] This utility model is achieved by the following technical solution: a particle screening device, including a separation base, a screening component is provided on the top of the separation base, and a screen assembly is provided on the top of the screening component.

[0006] The screening assembly includes a drive motor, which is fixedly connected to the surface of the separation base. A motor rotating rod is fixedly connected to the output end of the drive motor. A connecting rod is fixedly connected to the end of the motor rotating rod away from the drive motor. A screening rocker arm is fixedly connected to the end of the connecting rod away from the motor rotating rod. A limit rod is rotatably connected to the inner wall of the screening rocker arm. A limit ring is rotatably connected to the outer wall of the limit rod. A rotating rod is rotatably connected to the inner wall of the limit ring. A screen plate is fixedly connected to the end of the screening rocker arm away from the connecting rod.

[0007] As a further improvement to the above solution, the outer wall of the rotating rod is rotatably connected to the inner wall of the separation base, and there are two rotating rods, which are symmetrically arranged with the drive motor as the center.

[0008] Through the above technical solution, the drive motor is operated, the output end of the drive motor rotates the motor rotating rod, the motor rotating rod rotates the connecting rod, the connecting rod rotates the screening rocker arm, and at the same time the screening rocker arm is limited by the limit rod, so that the screening rocker arm rotates along the surface of the limit rod.

[0009] As a further improvement to the above solution, the screen assembly includes a limiting groove, which is formed on the inner wall of the screen plate. The screen is slidably connected to the inner wall of the limiting groove, and an avoidance groove is formed on the surface of the screen. A connecting bolt is threadedly connected to the inner wall of the avoidance groove.

[0010] As a further improvement to the above solution, the connecting bolt penetrates through the inner wall of the screen and extends therefrom, with the end of the connecting bolt away from the clearance groove threadedly connected to the inner wall of the screen plate.

[0011] As a further improvement to the above solution, the inner wall of the screen plate is provided with a discharge port, the inner wall of the discharge port is fixedly connected with an outlet filter screen, and a discharge connecting block is provided on the surface of the discharge port, and the discharge connecting block is fixedly connected to the surface of the screen plate.

[0012] As a further improvement to the above solution, three screens are provided, and four discharge ports are provided, with the four discharge ports arranged symmetrically around the center of the screen plate.

[0013] As a further improvement to the above solution, four outlet filters are provided, which are symmetrically arranged around the center of the screen disk, and four discharge connection blocks are provided, which are symmetrically arranged around the center of the screen disk.

[0014] The above technical solution involves installing the screen inside the limiting groove of the screen plate, then pressing the connecting bolts along the clearance groove of the screen, and finally connecting the screen to the screen plate with the connecting bolts. This allows for the installation of screening screens of different diameters in different layers, improving the flexibility of the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a drive motor to rotate a motor-driven rod, which in turn rotates a connecting rod. This connecting rod then rotates a screening rocker arm, which is simultaneously limited by a limiting rod. The screening rocker arm rotates along the surface of the limiting rod, which in turn drives the limiting rod, which in turn drives a limiting ring. This limiting ring, also limited by the rotating rod, rotates along the surface of the rotating rod, causing a large-angle shaking motion. This, in turn, causes the screening rocker arm to shake the screen disc, resulting in significant and angular shaking of the material inside the screen disc. This effectively separates the raw materials accumulated inside the screen disc, thus improving the screening efficiency.

[0017] This invention involves installing a screen inside a limiting groove in a screen plate, then pressing connecting bolts into the clearance groove of the screen, and finally connecting the screen to the screen plate using the connecting bolts. This allows for the installation of screening screens of different diameters in different layers, improving the flexibility of the equipment. When raw materials on the screen surface cannot fall, they will be discharged outward through the discharge port of the screen plate. At the same time, the raw materials are limited by the outlet filter as they are discharged from the outlet, preventing large-diameter materials from being accidentally discharged.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-6 The particle screening device of this embodiment includes a separation base 1, a screening component 2 is provided on the top of the separation base 1, and a screen component 3 is provided on the top of the screening component 2.

[0029] The screening assembly 2 includes a drive motor 201, which is fixedly connected to the surface of the separation base 1. A motor rotating rod 202 is fixedly connected to the output end of the drive motor 201. A connecting rod 203 is fixedly connected to the end of the motor rotating rod 202 away from the drive motor 201. A screening rocker arm 204 is fixedly connected to the end of the connecting rod 203 away from the motor rotating rod 202. A limiting rod 205 is rotatably connected to the inner wall of the screening rocker arm 204. A limiting ring 206 is rotatably connected to the outer wall of the limiting rod 205. A rotating rod 207 is rotatably connected to the inner wall of the limiting ring 206. A screen plate 208 is fixedly connected to the end of the screening rocker arm 204 away from the connecting rod 203.

[0030] The outer wall of the rotating rod 207 is rotatably connected to the inner wall of the separation base 1. There are two rotating rods 207, which are symmetrically arranged with the drive motor 201 as the center.

[0031] The screen assembly 3 includes a limiting groove 301, which is formed on the inner wall of the screen disk 208. A screen 302 is slidably connected to the inner wall of the limiting groove 301. An avoidance groove 303 is formed on the surface of the screen 302. A connecting bolt 304 is threadedly connected to the inner wall of the avoidance groove 303.

[0032] The connecting bolt 304 penetrates the inner wall of the screen 302 and extends thereafter. The end of the connecting bolt 304 away from the relief groove 303 is threadedly connected to the inner wall of the screen plate 208.

[0033] The inner wall of the screen plate 208 is provided with a discharge port 305. An outlet filter 306 is fixedly connected to the inner wall of the discharge port 305. A discharge connecting block 307 is provided on the surface of the discharge port 305 and is fixedly connected to the surface of the screen plate 208.

[0034] There are three screens 302 and four discharge ports 305, which are symmetrically arranged around the center of the screen plate 208.

[0035] There are four outlet filter screens 306, which are symmetrically arranged around the center of the screen disk 208. There are also four discharge connection blocks 307, which are symmetrically arranged around the center of the screen disk 208.

[0036] The implementation principle of a particle screening device in this embodiment is as follows: The drive motor 201 is operated, and the output end of the drive motor 201 rotates the motor rotating rod 202. The motor rotating rod 202 rotates the connecting rod 203, and the connecting rod 203 rotates the screening rocker arm 204. Simultaneously, the screening rocker arm 204 is limited by the limiting rod 205, causing the screening rocker arm 204 to rotate along the surface of the limiting rod 205. At the same time, the screening rocker arm 204 drives the limiting rod 205, which in turn drives the limiting ring 206. The limiting ring 206 is limited by the rotating rod 207, and simultaneously rotates along the surface of the rotating rod 207, thus causing a large-angle shaking. This causes the screening rocker arm 204 to drive the screen disk 208 to shake, thereby causing the material inside the screen disk 208 to shake significantly. The swaying angle allows the raw materials accumulated inside the screen disk 208 to be screened, thereby improving the screening effect. By installing the screen 302 inside the limiting groove 301 opened in the screen disk 208, and then pressing the connecting bolt 304 along the clearance groove 303 opened in the screen 302, the screen 302 is connected to the screen disk 208 by the connecting bolt 304. This allows screens of different diameters to be installed in different layers, improving the flexibility of the equipment. When the raw materials swaying on the surface of the screen 302 cannot fall, the raw materials on the surface of the screen 302 will be discharged outward through the discharge port 305 opened in the screen disk 208. At the same time, the raw materials are limited by the outlet filter 306 as they are discharged along the discharge port 305, preventing large-diameter raw materials from being discharged accidentally.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
