Description

Technical Field

[0001] The utility model belongs to the technical field of color sorting of granular raw materials, in particular to a color sorter for granular raw materials. Background Art

[0002] Color sorters use photoelectric detection technology to automatically separate particles of different colors from granular materials based on differences in their optical properties. Photoelectric color sorters are non-destructive sorting equipment used for quality inspection and grading of bulk materials, and are widely used in industries such as grain, food, pigments, and chemicals. They can separate harmful impurities such as plastic, glass, metal, and homochromic rods from grain, achieving internationally leading levels of performance. As a typical optomechanical system, color sorters involve innovation and application across all areas of optomechanical, electrical, and software.

[0003] However, in actual applications, many materials contain a lot of dust and other impurities before entering the color sorter. These impurities not only affect the sorting effect of the color sorter, but may also damage the precision components inside the machine, resulting in increased maintenance costs. For this reason, we propose a color sorter for granular raw materials. Utility Model Content

[0019] A color sorter for granular raw materials includes a support frame 1, a color sorter body 2 is mounted on the upper surface of the support frame 1, a plurality of discharge pipes 3 are provided at the bottom of the color sorter body 2, a screening mechanism 4 is mounted on one side of the support frame 1, and a transfer mechanism 5 is provided between the support frame 1 and the screening mechanism 4 for transporting the raw materials dropped from the screening mechanism 4 to the interior of the color sorter body 2;

[0020] The screening mechanism 4 includes a screening frame 401 arranged on one side of the support frame 1, and a support base 402 is installed in an array on the upper surface of the screening frame 401. A spring telescopic rod 403 is installed on the support base 402. A screening frame 404 is provided at the top of the spring telescopic rod 403. A screening partition net 405 is installed on the inner side of the screening frame 404. Vibration motors 406 are installed on both sides of the screening frame 404;

[0021] The material transfer mechanism 5 includes a material transfer frame 501 arranged between the support frame 1 and the screening frame 401, and a material transfer barrel 502 is installed on the upper surface of the material transfer frame 501. The inner wall of the material transfer barrel 502 is rotatably connected to a conveying auger 503. The surfaces on both sides of the material transfer barrel 502 are respectively installed with a first guide tube 504 and a second guide tube 505. The first guide tube 504 is connected to the screening frame 401, and the second guide tube 505 is connected to the color sorter body 2.

[0022] In a specific embodiment of the present invention, the granular raw materials can be pre-screened and dust-removed by the screening mechanism 4, which can effectively remove dust and impurities in the materials, and make the materials entering the color sorter body 2 purer, thereby improving the sorting accuracy and efficiency. Subsequently, the raw materials are transported to the interior of the color sorter body 2 through the material transfer mechanism 5. At this time, the raw materials are color-sorted by the color sorter body 2, and raw materials of different colors are discharged through multiple discharge pipes 3.

[0023] It should be noted that the color sorter body 2 is an existing technology, which mainly separates the granular materials and outputs them from different discharge pipes 3. Some of the separated granular materials will be put back into the screening mechanism 4 for re-color sorting.

[0024] Specifically, a feed hopper 407 is installed on the screening frame 404 , and a lower hopper 409 is installed on the lower surface of the screening frame 404 .

[0025] In a specific embodiment of the present invention, the feed hopper 407 is provided to facilitate the delivery of raw materials to the interior of the screening frame 404 , and the lower hopper 409 is provided to facilitate the diversion of raw materials falling from the screening partition net 405 to the interior of the first guide tube 504 .

[0026] The first guide tube 504 is connected to and communicates with the lower hopper 409. In the specific embodiment of the present invention, the positions of the first guide tube 504 and the second guide tube 505 are arranged to facilitate the transportation of raw materials and improve the transportation efficiency.

[0027] Specifically, a dust fan 408 is installed on the surface of the screening frame 404, and the dust fan 408 is arranged at an angle.

[0028] In a specific embodiment of the present invention, the dust fan 408 is provided to continuously blow air to the raw materials on the surface of the screen partition 405 , thereby removing dust in the raw materials.

[0029] Specifically, a servo motor 506 is installed at the bottom of the rotating rack 501, and the output shaft of the servo motor 506 and the end of the rotating shaft of the conveying auger 503 are fixedly connected with a pulley 507, and the two pulleys 507 are rotatably connected through a transmission belt 508.

[0030] In a specific embodiment of the present invention, when the servo motor 506 is started, its output shaft drives a pulley 507 to rotate, and at this time, the conveying auger 503 is driven to rotate under the action of the transmission belt 508 and the other pulley 507.

[0031] Specifically, a ladder 6 is installed on the surface of one side of the support frame 1 , and a blocking handrail 7 is installed on the upper surface of the support frame 1 and located outside the color sorter body 2 .

[0032] In a specific embodiment of the present invention, the provision of the escalator 6 facilitates the staff to inspect and observe the color sorter body 2, and the provision of the blocking handrail 7 can block the movement trajectory of the staff, thereby better protecting the staff.

[0033] Working principle: the raw material is poured into the feed hopper 407. At this time, the raw material falls on the surface of the screening mesh 405 under the action of gravity. The vibration motor 406 is started and drives the screening frame 404 and the screening mesh 405 to vibrate longitudinally under the action of the spring telescopic rod 403 and the support seat 402. At the same time, the dust fan 408 removes dust from the raw material. Under the action of vibration, the raw material passes through the screening mesh 405 and falls into the lower hopper 409. At this time, it enters the inside of the rotating drum 502 through the first guide pipe 504. When the servo motor 506 is started, its output shaft drives a pulley 507 to rotate. At this time, the conveying auger 503 is driven to rotate under the action of the transmission belt 508 and another pulley 507. At this time, the raw material is moved under the action of the conveying auger 503, and then the raw material is moved to the inside of the color sorter body 2 under the action of the second guide pipe 505. At this time, the raw material is color sorted by the color sorter body 2, and raw materials of different colors are discharged through multiple discharge pipes 3.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
