Description

Technical Field

[0001] This utility model relates to the field of antimony ore screening technology, specifically a vibrating fine screen antimony ore grading and refining device. Background Technology

[0002] Antimony can significantly improve the performance of alloys. Antimony compounds have good flame retardant properties and can be used to produce chemical products such as catalysts and pigments. Antimony exists in the earth's crust in the form of minerals (such as stibnite and stigmine). In the process of antimony mining, in order to improve the efficiency of subsequent processing and ensure product quality, a grading and sorting device is usually used to classify and screen the mined antimony ore.

[0003] When using existing grading and beneficiation equipment, antimony ore is usually fed into an inclined screen frame through a feeding hopper. The antimony ore moves downward along the inclined screen frame, and at the same time, the screen frame is vibrated by a vibrating motor, so that the antimony ore is graded and screened through the coarse and fine screens inside the screen frame during the movement.

[0004] Existing grading and refining devices have the following problems: in the screening process of antimony ore, screening is carried out solely by the vibration of the screen and the inertia of the antimony ore, resulting in poor screening effect and potential accumulation and blockage that affects the normal operation of the screening work. Therefore, we propose a vibrating fine screen antimony ore grading and refining device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a vibrating fine screen antimony ore grading and refining device. In the screening process of antimony ore, the antimony ore is moved back and forth by an auxiliary mechanism, making the antimony ore more loose during the movement, improving the screening effect, and avoiding the accumulation and blockage of antimony ore affecting the screening work. It can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vibrating fine screen antimony ore grading and beneficiation device, including a screening frame, a screen frame inside the screening frame, and an auxiliary mechanism;

[0007] Auxiliary mechanism: It includes a rotating shaft, cam, slide rod, push plate, support frame, scraper, linkage assembly, and reset assembly. The upper and lower sides of the front side of the screen frame are rotatably connected to cams through rotating shafts. The upper and lower rotating shafts are connected by a linkage assembly. Slide rods are slidably connected to the sliding holes on the upper and lower sides of the front side of the screen frame through a reset assembly. Push plates are provided at the front end of each slide rod. Support frames are fixedly fitted on the outer surface of each slide rod. Scrapers are evenly distributed on the lower surface of each support frame. During the screening of antimony ore, the auxiliary mechanism moves the antimony ore back and forth, making the antimony ore looser during movement, improving the screening effect, and avoiding the accumulation and blockage of antimony ore that would affect the screening work.

[0008] Furthermore, it also includes a microcontroller, which is located on the outside of the screening frame. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the control device.

[0009] Furthermore, a motor is provided on the front side of the screen frame. The left end of the motor's output shaft is fixedly connected to the right end of the upper rotating shaft, and the input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0010] Furthermore, the linkage component includes a synchronous pulley and a synchronous belt. The left end of the outer surface of the rotating shaft is fixedly fitted with a synchronous pulley, and the two synchronous pulleys are connected by a synchronous belt drive to facilitate the synchronous rotation of the two rotating shafts.

[0011] Furthermore, the reset assembly includes a limiting block, a sliding groove, and a spring. The rear end of each sliding rod is provided with a limiting block, and the rear side of the screen frame is provided with a sliding groove corresponding to the sliding hole. The limiting blocks are slidably connected to the inside of the sliding groove on the same side. The inside of each sliding groove is provided with a spring, which is located between the rear side of the adjacent limiting block and the rear wall of the sliding groove, facilitating the reset of the auxiliary mechanism.

[0012] Furthermore, the reset assembly also includes ribs and rib grooves. Ribs are provided on both the left and right sides of the outer surface of the limiting block, and rib grooves are provided on both the left and right sides of the sidewall of the slide groove. The ribs are slidably connected to the interior of the adjacent rib grooves, which facilitates the sliding limit of the slide rod.

[0013] Furthermore, a feeding hopper is provided on the right side of the upper surface of the screen frame, and a discharge hopper is provided on the lower surface of the screen frame. The screen frame is divided into upper and lower chambers, and coarse and fine screens are respectively provided in the mounting grooves on the bottom walls of the upper and lower chambers to facilitate screening.

[0014] Furthermore, a vibration motor is provided on the right side of the screen frame, and the input end of the vibration motor is electrically connected to the output end of the microcontroller to facilitate the vibration of the screen frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This vibrating fine screen antimony ore classification and beneficiation device has the following advantages:

[0016] During the screening process of antimony ore, the rotation of the shaft drives the cam to rotate. The rebound force of the spring drives the slide bar to move forward through the limit block. The slide bar drives the push plate to move, so that the front side of the push plate is always in contact with the outer surface of the adjacent cam. This causes the rotation of the shaft to drive the slide bar to slide back and forth through the cam. The movement of the slide bar drives the scraper to move back and forth through the support frame, which moves the antimony ore to loosen it during the movement, improves the screening effect, and avoids the accumulation and blockage of antimony ore that affects the screening work.

The screen frame 2 is divided into upper and lower chambers, and a coarse screen 9 and a fine screen 10 are respectively installed in the mounting grooves on the bottom walls of the upper and lower chambers. A vibrating motor 8 is located on the right side of the screen frame 2. The input of the vibration motor 8 is electrically connected to the output of the microcontroller 5. The operator feeds the antimony ore into the inclined screen frame 2, which is lower on the left and higher on the right, through the feeding hopper 6. The antimony ore moves from right to left along the inclined screen frame 2. Then, the microcontroller 5 is operated to turn on the vibration motor 8, so that the screen frame 2 vibrates. During the movement, the antimony ore is blocked by the coarse screen 9 and discharged from the screen frame 2 through the discharge port on the left side of the upper chamber through inertia and vibration. The medium-sized antimony ore is blocked by the fine screen 10 and discharged from the screen frame 2 through the discharge port on the left side of the lower chamber. The small antimony ore passes through the fine screen 10 and is discharged from the screen frame 2 through the dropping hopper 7.

[0026] Auxiliary mechanism 3 includes a rotating shaft 31, a cam 32, a slide rod 33, a push plate 34, a support frame 35, a scraper 36, a linkage assembly 37, and a reset assembly 38. The upper and lower sides of the front side of the screen frame 2 are rotatably connected to the cam 32 via the rotating shaft 31. The upper and lower rotating shafts 31 are connected by the linkage assembly 37. Slide rods 33 are slidably connected to the sliding holes on the upper and lower sides of the front side of the screen frame 2 via the reset assembly 38. Push plates 34 are provided at the front ends of the slide rods 33. Support frames 35 are fixedly fitted onto the outer surfaces of the slide rods 33. Scrapers 36 are evenly distributed on the lower surface of the support frame 35. 6. A motor 4 is provided on the front side of the screen frame 2. The left end of the output shaft of the motor 4 is fixedly connected to the right end of the upper rotating shaft 31. The input end of the motor 4 is electrically connected to the output end of the microcontroller 5. The linkage component 37 includes a synchronous pulley 371 and a synchronous belt 372. The left end of the outer surface of the rotating shaft 31 is fixedly fitted with a synchronous pulley 371. The two synchronous pulleys 371 are connected by a synchronous belt 372. The reset component 38 includes a limiting block 381, a sliding groove 382 and a spring 383. The rear end of the sliding rod 33 is provided with a limiting block 381. The rear side of the screen frame 2 is provided with a sliding groove 38 corresponding to the sliding hole. 2. Each limiting block 381 is slidably connected to the interior of the slide groove 382 on the same side. Each slide groove 382 is equipped with a spring 383, which is located between the rear side of the adjacent limiting block 381 and the rear wall of the slide groove 382. The reset assembly 38 also includes ribs 384 and rib grooves 385. Ribs 384 are provided on both the left and right sides of the outer surface of the limiting block 381, and rib grooves 385 are provided on both the left and right sides of the side wall of the slide groove 382. The ribs 384 are slidably connected to the interior of the adjacent rib grooves 385. Simultaneously, the motor 4 is turned on, and the output shaft of the motor 4 drives the upper rotating shaft 31 to rotate. The upper shaft 31 drives the lower shaft 31 to rotate synchronously via the synchronous pulley 371 and the synchronous belt 372. The rotation of the shaft 31 drives the cam 32 to rotate as well. Under the constraint of the rib 384 and the rib groove 385, the rebound force of the spring 383 drives the slide rod to move forward along the rib groove 385 through the limit block 381, causing the push plate 34 to move forward, so that the front side of the push plate 34 is always in contact with the outer surface of the adjacent cam 32. The rotation of the shaft 31 drives the slide rod 33 to slide back and forth through the cam 32. The movement of the slide rod 33 drives the scraper 36 to move back and forth through the support frame to move the antimony ore.

[0027] The working principle of the vibrating fine screen antimony ore grading and refining device provided by this utility model is as follows: The operator feeds antimony ore into the inclined screen frame 2 (left side lower than right side) through the feeding hopper 6. The antimony ore moves from right to left along the inclined screen frame 2. Then, the microcontroller 5 turns on the vibrating motor 8, causing the screen frame 2 to vibrate. During the movement, due to inertia and vibration, larger antimony ore is blocked by the coarse screen 9 and discharged from the screen frame 2 through the discharge port on the left side of the upper chamber. Medium-sized antimony ore is blocked by the fine screen 10 and discharged from the screen frame 2 through the discharge port on the left side of the lower chamber. Smaller antimony ore passes through the fine screen 10 and is discharged from the screen frame 2 through the discharge hopper 7. At the same time, the motor 4 is turned on... The output shaft of machine 4 drives the upper rotating shaft 31 to rotate. The upper rotating shaft 31 drives the lower rotating shaft 31 to rotate synchronously through the synchronous pulley 371 and the synchronous belt 372. The rotation of the rotating shaft 31 drives the cam 32 to rotate as well. Under the restriction of the rib 384 and the rib groove 385, the rebound force of the spring 383 drives the slide rod to move forward along the rib groove 385 through the limit block 381, causing the push plate 34 to move forward, so that the front side of the push plate 34 is always in contact with the outer surface of the adjacent cam 32. The rotation of the rotating shaft 31 drives the slide rod 33 to slide back and forth through the cam 32. The movement of the slide rod 33 drives the scraper 36 to move back and forth through the support frame 35 to move the antimony ore.
