Description

Technical Field

[0001] The utility model belongs to the field of color sorters, in particular to a blowing nozzle assembly of a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically sort out different-colored particles from granular materials based on the differences in the optical properties of the materials. The materials to be selected are discharged from the hopper at the upper part and enter the color sorter. Through the vibration feeding of the vibrator, the materials to be selected slide down the guide trough, and are usually transported by a conveyor belt to the sorting area at an appropriate level and initial velocity. The image of the material is collected by the image acquisition unit, and the control processing unit outputs a control signal to drive the nozzle to blow out the different-colored particles into the waste material chamber of the receiving hopper, and the good materials to be selected continue to fall into the finished product chamber of the receiving hopper. However, when the color sorter performs sorting operations for a long time in an environment with relatively high dust and water vapor, such as sorting glass and slag, the nozzle of the color sorter is easily blocked by mud similar to air-dried mud, resulting in the sorting machine being unable to sort materials normally.

[0016] In the above scheme, the lower plate 41 is fixed to the bottom of the mouthpiece body 10, and the middle plate 42 and the upper plate 43 extend from the lower plate 41 and fit with the fixed part 30b of the soft mouthpiece 30, playing a role of lifting and restraining, and limiting the separation of the soft mouthpiece 30 from the front part of the mouthpiece body 10 through the lower fixed plate 40.

[0017] Furthermore, a nozzle beam 50 is arranged above the nozzle body 10 and the soft nozzle 30, and the nozzle beam 50 includes a front beam plate 51 and a rear beam plate 52. The front beam plate 51 is provided with a positioning hole groove 511, and the positioning hole groove 511 and the upwardly protruding protrusion 32 on the upper side of the air guide part 30a form an embedded positioning fit.

[0018] The above scheme forms an embedded positioning fit through the positioning hole groove 511 located on the upper nozzle beam 50 and the upward protruding block 32 on the upper side of the air guide part 30a. While positioning to ensure the docking accuracy of the soft nozzle 30 and the nozzle body 10, the front beam plate 51 also has a restraining effect on the air guide part 30a. Through the joint cooperation of the lower fixed plate 40 and the front beam plate 51, the connection stability of the soft nozzle 30 and the nozzle body 10 is ensured.

[0019] Furthermore, the pressing mechanism 60 includes a roller seat plate 64, on which an upper roller 641 and a lower roller 642 are arranged, and the wheel cores of the upper roller 641 and the lower roller 642 are located on the plumb plane, and the upper roller 641 rolls from top to bottom on the front plate edge of the front beam plate 51, and the lower roller 642 rolls from bottom to top on the lower bottom surface of the air guide portion 30a.
