Description

Technical Field

[0001] This utility model relates to the field of heavy calcium carbonate raw material purification technology, specifically a color sorting device for heavy calcium carbonate raw material purification. Background Technology

[0002] Heavy calcium carbonate, as an important inorganic non-metallic material, is widely used in many fields such as plastics, rubber, papermaking, and coatings. In the production process of heavy calcium carbonate, color sorting is one of the key purification steps. It uses a color sorter to screen granular heavy calcium carbonate raw materials, separating substandard raw materials from good raw materials to ensure product quality.

[0003] When too much material overlaps in the screening device, the screening effect will be poor. When the high-speed spray valve is working, it may blow out defective material along with good material, or the defective material may be blocked by the good material and cannot be effectively screened out, thus requiring secondary screening. This not only increases production costs but also reduces production efficiency.

[0004] Based on this, a color sorting device for purifying heavy calcium carbonate raw materials is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a color sorting device for purifying heavy calcium carbonate raw materials, so as to solve the problems in the background art.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-3 As shown, a color sorting device for purifying heavy calcium carbonate raw materials includes a housing 100. A feed inlet 101 is provided at the top of the housing 100. A feed hopper 102 is provided at the upper end of the feed inlet 101. A guide plate 103 is provided at the upper end of the feed inlet 101. An auxiliary feeding mechanism for uniform feeding is provided in the feed hopper 102. A conveying component to prevent raw material overlap is provided at the lower end of the guide plate 103 in the housing 100. A color sorting component is provided at the lower end of the conveying component. A drive unit is provided on the housing 100. The raw material is placed in the feed hopper 102. The auxiliary feeding mechanism controls the feeding speed of the raw material to prevent excessive overlap, which would affect screening and purification. The guide plate 103 guides the raw material to the conveying component, which ensures the raw material is evenly spread, allowing the color sorting component to accurately identify and remove defective products. This significantly reduces the probability of misjudging good products and missing defective products, reduces secondary screening processes, and the drive unit reduces energy waste and extends equipment lifespan.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, the auxiliary feeding mechanism includes a distributing roller 201, which is rotatably connected to the feed hopper 102. Four distributing grooves 202 are evenly distributed on the outer end of the distributing roller 201. One end of the distributing roller 201 is fixedly connected to a grooved wheel 203. The grooved wheel 203 has four sliding grooves 204, which are connected to a moving rod 205. The moving rod 205 is fixedly connected to a connecting rod 206, which is fixedly connected to a notched circle 207. 07 is fixedly connected to the outer end of the rotating shaft 208, which is rotatably connected to the outer shell 100. When the raw material is poured into the feed hopper 102, the notch circle 207 rotates, driving the connecting rod 206 to rotate. The connecting rod 206 drives the moving rod 205 to rotate. The moving rod 205 intermittently drives the grooved wheel 203 to rotate. The grooved wheel 203 intermittently drives the distributing roller 201 to rotate. The distributing roller 201 intermittently feeds the material through the distributing trough 202 to prevent the raw material from overlapping too much and affecting the detection of the optical sensor.

[0025] In one embodiment, such as Figure 3 As shown, the conveying component includes a conveyor plate 301, which is inclinedly disposed within the housing 100. A fixing frame 302 is fixedly connected to the lower end of the conveyor plate 301. The fixing frame 302 is fixedly connected to a fixing plate 304 via a spring 303. The fixing plate 304 is fixedly connected to the housing 100. Evenly distributed dividing strips 305 are present on the conveyor plate 301. A rotating drum 306 is rotatably connected to the housing 100. Brush bristles 307 are provided at the outer end of the rotating drum 306. A vibration motor 308 is fixedly connected to the fixed frame 302. When the vibration motor 308 is started, it drives the fixed frame 302 to vibrate, which in turn drives the conveyor plate 301 to vibrate. The raw materials fall onto the conveyor plate 301 and spread evenly as the conveyor plate 301 vibrates. The evenly distributed separators 305 make the raw materials more stable, uniform, and neatly arranged during the conveying process. The rotating drum 306 with brush bristles 307 can separate the overlapping raw materials, allowing the air gun to accurately identify and remove defective products.

[0026] In one embodiment, such as Figure 3As shown, the color sorting component includes a first mounting plate 401, which is fixedly connected to the lower end of the material conveying plate 301 on the outer casing 100. A second mounting plate 402 parallel to the first mounting plate 401 is provided on the upper side of the first mounting plate 401. A row of linearly distributed optical sensors 403 are fixedly connected to the first mounting plate 401 and the second mounting plate 402 respectively. Lamp bodies 404 are provided on both sides of the optical sensors 403. A row of air guns 405 corresponding to the optical sensors 403 is fixedly connected to the first mounting plate 401. The raw material falling downwards passes between the two optical sensors 403 and is detected. When non-conforming raw material is detected, the corresponding air gun 405 is controlled to spray airflow to blow out the non-conforming raw material, thereby separating the defective raw material from the good raw material.

[0027] In one embodiment, such as Figure 2 As shown, the drive unit includes a motor 501, which is fixedly connected to the housing 100. The output end of the motor 501 is fixedly connected to pulley 502. Pulley 502 is connected to pulley 503 via a belt. Pulley 503 is fixedly connected to the outer end of the rotating shaft 208. Pulley 504 is fixedly connected to the outer end of the rotating shaft 208. Pulley 504 is connected to pulley 505 via a belt. Pulley 505 is fixedly connected to the rotating drum 306. The motor 501 drives pulley 502 to rotate, which in turn drives pulley 503 to rotate. Pulley 503 drives the rotating shaft 208 to rotate, thereby driving the auxiliary feeding mechanism to operate. The rotating shaft 208 drives pulley 504 to rotate, which in turn drives pulley 505 to rotate. Pulley 505 drives the rotating drum 306 to rotate. By using the power output of a single motor 501, energy waste caused by multiple motors is avoided, and the service life of the equipment is extended.

[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, the lower side of the mounting plate 401 is provided with a good raw material collection tank 601 and a defective raw material collection tank 602. A good raw material collection box 603 and a defective raw material collection box 604 are slidably connected in the good raw material collection tank 601 and the defective raw material collection tank 602, respectively, so that good and defective products are collected separately and in independent collection boxes. This facilitates the subsequent classification, statistics and accounting of raw materials of different qualities. When the collection box is full, it can be quickly pulled out and replaced, avoiding the interruption of the screening process due to waiting for raw materials to be emptied, and effectively improving the continuity of production.

[0029] In one embodiment, such as Figure 1 As shown, the lower end of the housing 100 is provided with four casters 700. The casters 700 enable the color sorting device to move easily within the workshop, making it convenient to adjust the equipment position according to the production layout and saving manpower and time costs.

[0030] In one embodiment, such as Figure 2 As shown, the four sliding grooves 204 are evenly distributed on the groove wheel 203, driving the raw materials to fall and discharge sequentially at equal time intervals, effectively achieving stable and uniform output of raw materials and avoiding problems such as accumulation or uneven conveying caused by concentrated feeding.

[0031] The above embodiment discloses a color sorting device for purifying heavy calcium carbonate raw materials. The raw material is placed in the feed hopper 102. The notched circle 207 rotates, driving the connecting rod 206 to rotate. The connecting rod 206 drives the moving rod 205 to rotate. The moving rod 205 intermittently drives the grooved wheel 203 to rotate. The grooved wheel 203 intermittently drives the distributing roller 201 to rotate. The distributing roller 201 intermittently feeds the material through the distributing trough 202. A vibration motor 308 is started, driving the fixed frame 302 to vibrate. The fixed frame 302 drives the conveying plate 301 to vibrate. The material falls onto the conveyor plate 301, and as the conveyor plate 301 vibrates, it is spread evenly. The evenly distributed separators 305 make the material more stable, uniform, and neatly arranged during the conveying process. The rotating drum 306 with brush bristles 307 can separate the overlapping materials, allowing the air gun to accurately identify and remove defective products. The falling material passes between two optical sensors 403 for detection. When non-conforming material is detected, the corresponding air gun 405 is controlled to spray airflow to blow out the non-conforming material, thereby separating the defective material from the good material.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
