Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus processing technology, and in particular to a sorting and batching device for yellow phosphorus processing. Background Technology

[0002] In the production process of yellow phosphorus, phosphate rock, coke and a small amount of silica need to be sorted to the appropriate particle size and then batched in proportion.

[0003] Chinese document CN215784801U discloses a vibration-assisted sorting device for yellow phosphorus production, mainly composed of a housing and a screen. The screen is located inside the housing, and a drive motor is installed on the outer wall of the housing. The device includes: a fixing component fixed to the inner wall of the housing; both ends of the screen are connected to the fixing component via springs; protrusions are installed on the outer wall of a first rotating shaft; and the first and second rotating shafts are connected by a first transmission belt. In this vibration-assisted sorting device for yellow phosphorus production, a first rotating shaft is located below the screen, and two teardrop-shaped protrusions are installed on the outer wall of the first rotating shaft. The protrusions and the screen are always in contact with each other. When the first rotating shaft drives the protrusions to rotate, it causes the screen to vibrate up and down, thereby accelerating the sorting process of the yellow phosphorus raw materials and effectively preventing clogging.

[0004] Because phosphate rock and coke often contain small amounts of metal debris such as iron nails and iron wires, the sorting equipment used in the production of yellow phosphorus cannot screen out the metal debris during use. The metal debris enters the electric furnace, which may cause short circuits and damage to the furnace wall, reducing the safety factor of the yellow phosphorus processing process. Utility Model Content

[0005] The purpose of this utility model is to provide a sorting and batching device for yellow phosphorus processing, which can solve the problem that because phosphate rock and coke often contain a small amount of metal debris such as iron nails and iron wires, the sorting equipment used in yellow phosphorus production cannot screen out the metal debris during use. The metal debris enters the electric furnace, which may cause short circuits and damage to the furnace wall, thus reducing the safety factor of the yellow phosphorus processing process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sorting and batching device for yellow phosphorus processing, comprising a sorting box, a metal screening mechanism, and a screening auxiliary mechanism. The metal screening mechanism is disposed inside the sorting box and includes a movable rod, a connecting rod, and a hollow drum. The movable rod is rotatably mounted on the inner walls of the front and rear sides of the sorting box, and multiple sets of annularly distributed connecting rods are fixedly mounted on the outer walls of the movable rod. One end of the connecting rod is fixedly connected to the inner wall of the hollow drum. The screening auxiliary mechanism is disposed inside the sorting box and includes a rotating rod and cams. Two sets of rotating rods are rotatably mounted on the inner walls of the front and rear sides of the sorting box, and the outer walls of the two sets of rotating rods are fixedly connected to the interior of multiple sets of cams.

[0007] Preferably, the metal screening mechanism further includes a servo motor and magnets. The servo motor is fixedly installed on the rear side of the sorting box, and the output shaft of the servo motor is fixedly connected to one end of the movable rod. The other end of the movable rod extends to the outside of the sorting box. Multiple sets of ring-shaped magnets are fixedly installed on the inner wall of the hollow drum. A scraper is fixedly installed on one side of the inner wall of the sorting box. The scraper is in contact with but not connected to the outer wall of the hollow drum, which can adsorb metal and screen out metal fragments that may be mixed in phosphate rock and coke. This prevents metal fragments from entering the electric furnace with the yellow phosphorus raw material, prevents equipment failure, and improves the safety factor of the yellow phosphorus processing process.

[0008] Preferably, the screening auxiliary mechanism further includes a large synchronous wheel, a synchronous belt, and a small synchronous wheel. The outer wall of the movable rod is fixedly connected to the inside of the large synchronous wheel, and one end of the rotating rod extends to the outside of the sorting box. A set of small synchronous wheels is fixedly installed on the outer walls of the two sets of rotating rods respectively. A synchronous belt is sleeved between the small synchronous wheel and the large synchronous wheel to continuously strike the bottom of the coarse-mesh screen and the fine-mesh screen. The auxiliary device performs grading and screening of the raw materials for yellow phosphorus production, ensuring the fineness of the screening. No additional drive equipment is required, which reduces the production and operating costs of the device.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a sorting and batching device for yellow phosphorus processing, including a sorting box 1, a metal screening mechanism 2, and a screening auxiliary mechanism 3. The metal screening mechanism 2 is disposed inside the sorting box 1 and includes a movable rod 202, a connecting rod 203, and a hollow drum 204. The movable rod 202 is rotatably mounted on the inner walls of the front and rear sides of the sorting box 1, and multiple sets of annularly distributed connecting rods 203 are fixedly mounted on the outer wall of the movable rod 202. One end of the connecting rod 203 is fixedly connected to the inner wall of the hollow drum 204. The screening auxiliary mechanism 3 is disposed inside the sorting box 1 and includes... The sorting box 1 includes rotating rods 301 and cams 302. Two sets of rotating rods 301 are rotatably installed on the inner walls of the front and rear sides of the sorting box 1. The outer walls of the two sets of rotating rods 301 are fixedly connected to the interior of multiple sets of cams 302. Coarse-mesh screens 4 and fine-mesh screens 5 are fixedly installed on the inner walls of both sides of the sorting box 1. The coarse-mesh screen 4 is located above the fine-mesh screen 5, and the two sets of rotating rods 301 are located below the coarse-mesh screen 4 and the fine-mesh screen 5, respectively. A feed hopper 6 is fixedly installed on the top of the sorting box 1, and discharge pipes 7 are fixedly installed on both sides of the sorting box 1. A material box 9 is snapped onto one side of the sorting box 1. A tray 8 is slidably installed on the bottom inner side of the sorting box 1.

[0024] Secondly, the metal screening mechanism 2 also includes a servo motor 201 and a magnet 205. The servo motor 201 is fixedly installed on the rear side of the sorting box 1. The output shaft of the servo motor 201 is fixedly connected to one end of the movable rod 202. The other end of the movable rod 202 extends to the outside of the sorting box 1. Multiple sets of ring-shaped magnets 205 are fixedly installed on the inner wall of the hollow drum 204. A scraper 206 is fixedly installed on one side of the inner wall of the sorting box 1. The scraper 206 is attached to but not connected to the outer wall of the hollow drum 204, which can adsorb metal and screen out metal fragments that may be mixed in phosphate rock and coke. This prevents metal fragments from entering the electric furnace with the yellow phosphorus raw material, prevents equipment failure, and improves the safety factor of the yellow phosphorus processing process.

[0025] Furthermore, the screening auxiliary mechanism 3 also includes a large synchronous wheel 303, a synchronous belt 304, and a small synchronous wheel 305. The outer wall of the movable rod 202 is fixedly connected to the inside of the large synchronous wheel 303. One end of the rotating rod 301 extends to the outside of the sorting box 1. A set of small synchronous wheels 305 are fixedly installed on the outer walls of the two sets of rotating rods 301 respectively. A synchronous belt 304 is sleeved between the small synchronous wheel 305 and the large synchronous wheel 303, continuously striking the bottom of the coarse-mesh screen 4 and the fine-mesh screen 5. The auxiliary device performs grading and screening of the raw materials for yellow phosphorus production, ensuring the fineness of the screening. No additional drive equipment is required, reducing the production and operating costs of the device.

[0026] Working principle: When in use, the servo motor 201 drives the movable rod 202 to rotate, which in turn drives the hollow drum 204 to rotate. The raw materials for preparing yellow phosphorus are fed into the sorting box 1 through the feed hopper 6 and slide down the side wall of the hollow drum 204. The magnet 205 attracts metal debris from the raw materials to the surface of the hollow drum 204. As the hollow drum 204 rotates, the scraper 206 scrapes off the metal debris attracted on the hollow drum 204 and it falls into the material box 9 for storage. The remaining raw materials fall onto the coarse-mesh screen. On screen 4, when the movable rod 202 rotates, it drives the large synchronous wheel 303 to rotate. Through the synchronous belt 304, it drives the small synchronous wheel 305 to rotate, which in turn drives the two sets of rotating rods 301 to rotate simultaneously. This causes the cam 302 to strike the bottom of the coarse-hole screen 4 and the fine-hole screen 5, so that the coarse-hole screen 4 screens out the raw materials with excessively large particles and discharges them through the discharge pipe 7. Then, the fine-hole screen 5 screens out the raw materials with excessively small particle sizes and collects them in the tray 8. The raw materials with the correct particle size are discharged through another set of discharge pipes 7.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
