Description

Technical Field

[0001] The invention relates to the technical field of color sorters, and in particular to a dust removal method applicable to the field of color sorters. Background Art

[0002] Color sorter is a device used to sort and remove impurities or particles of different colors from materials. It is widely used in food processing (such as rice, beans, tea, etc.), chemical industry, mining and other industries. Its working principle is that the material is transported to the chute or belt by the vibrating feeder, and the material slides (falls) to the camera imaging point, reflecting different spectral characteristics under the irradiation of strong light. The signal processor analyzes the received spectral data and identifies the color or foreign matter that does not meet the set standards. Dust and light materials have a great impact on the performance of the color sorter.

[0003] The existing color sorter dust removal device is relatively simple in design and has a single application scenario. The gas flow needs to be manually adjusted. Different materials require different air volumes. Excessive air volume will take away normal materials, while too small air volume cannot meet the dust removal effect. Therefore, a dust removal method suitable for the field of color sorters is proposed. Summary of the invention

[0007] The dust collection assembly includes an exhaust pipe arranged on one side of the color sorter, the exhaust pipe is fixedly connected to a branch pipe extending to the top of the feeding tray, the other end of the branch pipe is fixedly connected to a dust collection hood located above the feeding tray, one end of the exhaust pipe is fixedly connected to a closed end cover, and the closed end cover is provided with a gas guide port.

[0008] Through the above technical scheme, the blowing component is installed on the color sorter using the mounting frame. When color sorting and dust removal are performed, the material is placed on the feeding tray and then falls from the end of the feeding tray to the slide. The blowing component performs an oblique upward blowing operation on the material that falls on the slide. The dust in the material and the light material are transported upward along the slide to the dust collection component and then are extracted and transported by the dust collection component.

The rotating shaft 1 drives the retaining plate to move under the action of the guide groove 1. Due to the restrictions of the closing plate and the storage plate at the end of the adjustment plate, the retaining plate and the adjustment plate can only slide along the length direction of the closing plate. When adjusting the position of the adjustment plate, the end of the adjustment plate is closed by the closing plate and the storage plate, and the front end of the adjustment plate is closed by the end plate, the connecting seat 1 and the connecting seat 2, so as to prevent wind from blowing out from the top of the adjustment plate.

[0050] Embodiment 5:

[0051] A dust removal method for a dust removal structure applicable to the field of color sorting machines, comprising the following steps:

[0052] Step S1, design and process the dust removal structure, and select a suitable number of branch pipes 62, partitions 53 and adjustment mechanisms 54 according to the size of the color sorter and the number of feed trays 3;

[0053] Step S2, installing the dust removal structure, installing the processed dust removal structure on the color sorter 1;

[0054] Step S3, dust removal by dust removal structure: when the color sorter 1 is performing dust removal, the dust removal operation is performed by using the dust removal structure of the controller hole on the color sorter 1.

[0055] Working principle:

[0056] The blowing assembly 5 is installed on the color sorter 1 by using the mounting frame 4. When color sorting and dust removal are performed, the material is put on the feeding tray 3, and then falls from the end of the feeding tray 3 to the slide 2. The blowing assembly 3 performs an oblique upward blowing operation on the material falling on the slide 2, and the dust in the material and the light material are transported upward along the slide 2 to the dust collection assembly 6, and then are extracted and transported by the dust collection assembly 6. When the material is blown and dusted, the blowing width and size are adjusted according to the material type by using the adjustment mechanism 54, so as to realize the blowing and dust removal operation of different types of materials;

[0057] During adjustment, the laser particle detector first detects the particle size of the material discharged from the feeding tray 2 and determines the material diameter, so as to facilitate the subsequent adjustment of the blowing size and direction. When adjusting the blowing size, on the one hand, the controller is used to control the fan speed, and on the other hand, the position of the adjustment plate 76 is adjusted to adjust the width and size of the wind ejected from the nozzle 52. Wind forces of different widths and sizes can give different speeds and blowing times to dust and light materials, so as to achieve the blowing separation operation of particles, dust and light materials according to the particle size of the materials. For logistics with smaller particles, a blowing with a longer width and slightly smaller wind force can be used to separate dust and light materials from materials.

[0058] When adjusting the position of the adjustment plate 76, the motor is started, the adjustment shaft 71 rotates, and then the pull rod 72 moves. The rotating shaft 73 drives the retaining plate 74 to move under the action of the guide groove 75. Due to the restrictions of the closing plate 713 and the receiving plate 714 at the end of the adjustment plate 76, the retaining plate 74 and the adjustment plate 76 can only slide along the length direction of the closing plate 713. When adjusting the position of the adjustment plate 76, the end of the adjustment plate 76 is closed by the closing plate 713 and the receiving plate 714, and the front end of the adjustment plate 76 is closed by the end plate 78, the connecting seat 1 77 and the connecting seat 2 79 to prevent wind from blowing out from the top of the adjustment plate 76.

[0059] The design adopts the method of blowing air obliquely upward from one side of the material and sucking and exhausting dust from the top of the material to quickly separate the dust in the material and the light material from the material, thus realizing the rapid dust removal operation of the material; the wind force size and wind force width adjustment of the blowing dust removal are realized, which is suitable for the rapid dust removal and separation operation of materials of different particle sizes, thereby improving the application scope of material dust removal, facilitating adjustment and use, reducing the difficulty of adjustment for operators, and improving the efficiency and quality of material color sorting.

[0060] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
