[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a miniaturized and automated device for separating chromite sand, including a main body plate 1 and a screening mechanism 2. The screening mechanism 2 is arranged on one side of the surface of the main body plate 1, and a storage mechanism 3 is arranged at one end of the main body plate 1;
[0021] The screening mechanism 2 includes a feed inlet 201, a rotating groove 202, a mounting groove 203, a gear ring 204, a cylinder 205, a rack 206, a first screening barrel 207, a first threaded groove 208, a second screening barrel 209, a second threaded groove 210, a third screening barrel 211, screening holes 212, and a metal filter screen 213. On one side of the surface of the main body plate 1, there is a feed inlet 201 opened. At one end of the feed inlet 201, there is a rotating groove 202 opened. On one side of the rotating groove 202, there is a mounting groove 203 opened. Inside the rotating groove 202, there is a gear ring 204 fitted. Inside the mounting groove 203, there is a cylinder 205 installed. On the surface of the gear ring 204, there is a rack 206 engaged. At one end of the gear ring 204, there is a first screening barrel 207 fixedly connected. On the other side of the first screening barrel 207, there is a first threaded groove 208 opened. Inside the first threaded groove 208, there is a second screening barrel 209 threadedly connected. On the other side of the second screening barrel 209, there is a second threaded groove 210 opened. Inside the second threaded groove 210, there is a third screening barrel 211 threadedly connected. Inside the third screening barrel 211, there are screening holes 212 opened. Inside the screening holes 212, there is a metal filter screen 213 installed. Through the settings of the feed inlet 201, the rotating groove 202, the mounting groove 203, the gear ring 204, the cylinder 205, the rack 206, the first screening barrel 207, the first threaded groove 208, the second screening barrel 209, the second threaded groove 210, the third screening barrel 211, the screening holes 212, and the metal filter screen 213, materials enter the screening mechanism 2 through the feed inlet 201 on one side of the surface of the main body plate 1. The materials entering the feed inlet 201 first enter into the first screening barrel 207. The cylinder 205 is fixed through the mounting groove 203 and is connected to the rack 206. After starting the cylinder 205, it drives the rack 206 to move along the surface of the gear ring 204. The rotation of the gear ring 204 causes the first screening barrel 207 to start rotating. The materials are preliminarily screened in the first screening barrel 207 and filtered through the screening holes 212 and the metal filter screen 213. The first screening barrel 207 and the second screening barrel 209 are connected through the first threaded groove 208. The larger particles after screening will enter the second screening barrel 209 for further screening. The second screening barrel 209 is also connected to the third screening barrel 211 through the second threaded groove 210. The aperture diameters of the screening holes 212 on each screening barrel are different, so as to screen out materials of different sizes.
[0022] Further, a rack 206 is fixedly connected to one side of the cylinder 205. The toothed ring 204 and the rack 206 form a sliding structure through the cylinder 205. Through the arrangement of the cylinder 205 and the rack 206, the cylinder 205 is the power source in the screening mechanism 2. Its main function is to drive the movement of the rack 206. When the cylinder 205 is started, the piston rod will extend or retract, driving the rack 206 fixed on one side to perform a linear motion. The telescopic motion of the cylinder 205 directly controls the forward and backward movement of the rack 206. This linear motion is converted into the rotational motion of the toothed ring 204, thereby driving the screening barrels (the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211) to rotate. At the same time, the tooth surfaces of the rack 206 and the toothed ring 204 are meshed. The linear movement of the rack 206 is converted into the rotational motion of the toothed ring 204 through meshing with the toothed ring 204. When the rack 206 is pushed by the cylinder 205, the rack 206 slides along the tooth surface of the toothed ring 204, forcing the toothed ring 204 to rotate, so that the first screening barrel 207 connected to the toothed ring 204 rotates. The moving direction and speed of the rack 206 directly affect the rotational speed and direction of the screening barrel, thereby adjusting the working state of the screening barrel to ensure that the material can be fully screened.
[0023] Further, screening holes 212 are provided on both the first screening barrel 207 and the second screening barrel 209. The pore diameters of the screening holes 212 on the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211 are different. Through the arrangement of the screening holes 212, the screening holes 212 are located inside the screening barrel. Through the screening holes 212, the material is classified and screened. The pore diameters of the screening holes 212 on each screening barrel gradually decrease. Therefore, small particle materials will remain in the first screening barrel 207, medium particle materials will enter the second screening barrel 209 through the first screening barrel 207 for further screening, and finally the largest particle materials will enter the collection box 301 through the screening holes 212 of the third screening barrel 211. The screening holes 212 of different sizes are evenly distributed on the screening barrel, enabling the material to fully contact the screening holes 212 during rotation, ensuring that the screening process is uniform and accurate. At the same time, due to the different pore diameters of the screening holes 212, the device can achieve multi-stage separation of the material, and materials of different particle sizes are separated into the corresponding collection boxes 301, thereby achieving an accurate screening effect. Finally, inside the screening holes 212, a metal filter screen 213 is installed to further improve the screening effect. The metal filter screen 213 can intercept particulate matter of a specific size, preventing incompletely screened materials from passing through the screening holes 212 into the next stage, ensuring the purity and quality of the screening.
[0024] Further, the apertures of the screening holes 212 on the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211 of the metal filter screen 213 are different, and the screening holes 212 are evenly distributed on the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211. Through the setting of the metal filter screen 213, the metal filter screen 213 is installed inside the screening holes 212 to further filter and screen the materials. Although the screening holes 212 have initially classified and screened the materials, the metal filter screen 213 can filter out finer particles to ensure that only the materials meeting the size requirements can pass through the screening holes 212 and enter the next screening barrel or the collection box 301. At the same time, the presence of the metal filter screen 213 can prevent large particles or incompletely screened materials from directly passing through the screening holes 212, thereby avoiding clogging of the screening holes 212. In this way, the metal filter screen 213 can maintain the continuity and smoothness of the screening process, reduce the downtime maintenance time of the equipment, and improve work efficiency. Finally, the metal filter screen 213 forms a protective barrier at the front end of the screening holes 212, which can effectively reduce the direct impact of large particle materials on the screening holes 212 and extend the service life of the screening holes 212.
[0025] Further, the storage mechanism 3 includes a collection box 301, a discharge port 302, a rotating shaft 303, a rotating door 304, tempered glass 305, and a handle 306. One end of the main body plate 1 is fixedly connected to the collection box 301. The two sides of the collection box 301 are provided with discharge ports 302. One side of the discharge port 302 is provided with a rotating shaft 303. The surface of the rotating shaft 303 is fixedly connected to the rotating door 304. The tempered glass 305 is installed inside the rotating door 304. One end of the rotating door 304 is fixedly connected to the handle 306. Through the setting of the collection box 301, the discharge port 302, the rotating shaft 303, the rotating door 304, the tempered glass 305, and the handle 306, the screened materials enter the corresponding collection box 301 through the screening holes 212. The first three collection boxes 301 correspond to the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211 respectively. At the same time, each collection box 301 is provided with a discharge port 302. The rotating door 304 can be rotated and opened or closed through the rotating shaft 303 to control the discharge of the materials. The size of the discharge port 302 matches that of the rotating door 304. When the materials need to be discharged, the rotating door 304 is opened through the handle 306, and the materials can be discharged from the discharge port 302.
[0026] Further, four sets of collection bins 301 are provided. The first three sets of collection bins 301 are respectively aligned with the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211. Through the arrangement of the collection bins 301, the collection bins 301 are located below the screening barrels and correspond to the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211 respectively, and are used to collect and store materials with different particle sizes screened out through the screening holes 212 of each screening barrel. Each collection bin 301 is aligned with the corresponding screening barrel, so that materials of different grades can directly fall into the corresponding collection bin 301 after screening, thereby realizing the classified storage of materials. Finally, the arrangement of multiple collection bins 301 can receive the materials screened out by different screening barrels at the same time, ensuring that the materials during the screening process are not mixed, thereby improving the screening efficiency and effect.
[0027] Further, the rotating door 304 and the collection bin 301 form a rotating structure through the rotating shaft 303. The size of the rotating door 304 matches that of the discharge port 302. Through the arrangement of the rotating door 304, the rotating door 304 is installed on the discharge port 302 of the collection bin 301 and is responsible for controlling the discharge of materials. When it is necessary to discharge materials, the rotating door 304 can be rotated through the handle 306 to open it, so that the materials can be smoothly discharged from the collection bin 301. At the same time, the size of the rotating door 304 matches that of the discharge port 302 to ensure that the discharge port 302 can be completely covered when it is closed, preventing accidental leakage of materials. Finally, the rotating door 304 can effectively seal the collection bin 301 in the closed state, preventing external dust, moisture or other pollutants from entering the interior of the collection bin 301 and keeping the materials clean and safe.
[0028] Working principle: Materials enter the screening mechanism 2 through the feed inlet 201 on one side of the surface of the main body plate 1. The materials entering the feed inlet 201 first enter the first screening barrel 207. The cylinder 205 is fixed through the mounting groove 203 and is connected to the rack 206. After starting the cylinder 205, it drives the rack 206 to move along the surface of the toothed ring 204. The rotation of the toothed ring 204 causes the first screening barrel 207 to start rotating. The materials are preliminarily screened in the first screening barrel 207 and filtered through the screening holes 212 and the metal filter screen 213. The first screening barrel 207 is connected to the second screening barrel 209 through the first threaded groove 208. The larger particulate matters after screening will enter the second screening barrel 209 for further screening. The second screening barrel 209 is also connected to the third screening barrel 211 through the second threaded groove 210. The apertures of the screening holes 212 on each screening barrel are different to screen out materials of different sizes. The screened materials enter the corresponding collection boxes 301 through the screening holes 212. The first three collection boxes 301 correspond to the first screening barrel 207, the second screening barrel 209, and the third screening barrel 211 respectively. At the same time, each collection box 301 is provided with a discharge port 302. The rotating door 304 can be rotated open and closed through the rotating shaft 303 to control the discharge of materials. The size of the discharge port 302 matches that of the rotating door 304. When it is necessary to discharge the materials, the rotating door 304 is opened through the handle 306, and the materials can be discharged from the discharge port 302.
