Description

Technical Field

[0001] This application belongs to the field of dual-selection machines, and specifically relates to a three-product dry separator with dual injection modules. Background Art

[0002] An intelligent dry separator is an advanced material screening and sorting device. It mainly relies on the physical properties of materials and advanced imaging and artificial intelligence technologies, and then through an execution module, different materials are sorted into different bins or chutes to achieve material sorting. Intelligent dry separators can be widely used in industries such as the coal industry, building materials industry, agricultural product processing, food processing, medicine, and cosmetics. With its advantages of high precision, high efficiency, and high intelligence, it plays an important role in many fields and is one of the important devices for modern production.

[0003] Currently, the execution module generally uses a jet execution mechanism to achieve material sorting through jetting. Jet sorting has the advantages of high efficiency and reliability. Through the instantaneous high-pressure gas generated by the opening of the solenoid valve after the previous identification, the objects to be removed are jetted, thereby changing the movement trajectory of the materials, separating the objects to be removed from the materials on the established trajectory, and thus achieving the purpose of material separation. Therefore, the existing three-product dry separator can achieve material separation through two jetting modules. The two jetting modules can change the throwing trajectories of two products, and the other product can be separated from the other two products by falling along the established trajectory. To change the throwing trajectories of the two products, in the patent with the patent application number 202021077029.7, the objects to be removed are hit to the first chute (the chute farthest from the feeder) and the third chute (the chute closest to the feeder) by arranging the two jetting modules opposite to each other, and the other product falls along the established trajectory to the second chute between the first chute and the second chute. Although the jetting modules arranged opposite to each other can achieve the separation of three products, these two jetting modules need to be fixedly connected through corresponding devices, resulting in problems of complex structure, non-compactness, and large volume.

[0004] Therefore, there is an urgent need for a three-product dry separator with dual jetting modules that has a simple, compact, and appropriate volume. Summary of the Utility Model

[0029] The present application provides a three-product dry separator with a double-blowing module, as Figure 1 shown.

The first chute 41 is located on the side far from the feeding device 1 and is used to accommodate the materials moving along the first dropping trajectory Z formed by the second blowing module 31 and gravity. The first blowing module and the second blowing module are arranged on the same side of the material dropping trajectory, making the structure of the dry separator simple, compact, and of appropriate volume.

[0031] Further, as Figure 1As shown, the first injection module and the second injection module respectively have a first injection direction and a second injection direction, and the included angle between the first injection direction and the second injection direction is 40° to 90°.

The third partition plate 43 can not only guide the materials of the second throwing trajectory Y into the second chute 42, but also guide the materials thrown onto the slope surface of the third partition plate 43 into the first chute 41, ensuring the orderliness, accuracy and reliability of material sorting. And the third partition plate 46 is rotatably and lockably connected to the top end of the second partition plate 45, so that the included angle between the third partition plate 46 and the second partition plate 45 is adjustable, ensuring the flexibility and adaptability during the operation process and further ensuring the accuracy and reliability of material sorting. Therefore, the three-product dry separator in the present application ensures the simplicity, compactness and appropriate volume of the structure while also ensuring the flexibility of the operation and the accuracy and reliability of sorting.

[0032] In some preferred embodiments of the present application, the included angle between the first injection direction and the second injection direction is 45°, so that the distance between the second throwing trajectory Y and the first throwing trajectory Z is appropriate, to ensure the accuracy and reliability of material sorting to the greatest extent.

The solenoid valve 36 is used to control the on-off of the gas path between the gas supply system and the first nozzles and the second nozzles. Moreover, the dust-proof plate 313 protects the gas path and also protects the solenoid valve 36, extending the service life of the solenoid valve 36.
