Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, specifically to a multi-layer nozzle device for a color sorter. Background Technology

[0002] CN217411573U discloses a multi-layer nozzle device for a color sorter, comprising an upper nozzle body with a plurality of parallel upper nozzle holes and lower nozzle holes formed on its upper and lower end faces; an upper air inlet for connecting to an air guide pipe and communicating with the upper nozzle holes; a lower nozzle body that overlaps the upper nozzle body; the lower nozzle body cooperating with the lower nozzle holes to form a lower air outlet at the tail end of the lower nozzle holes; a lower air inlet provided in the lower nozzle body and communicating with the lower nozzle holes; and a nozzle cover plate assembled with the upper nozzle body and cooperating with the upper nozzle holes to form an upper air outlet at the tail end of the upper nozzle holes.

[0003] By setting up a double-layer nozzle orifice, it solves the problem that existing color sorters are unable to sort large-sized, high-density materials.

[0004] However, during material color sorting, the material is shaken and enters the blowing path. The gas emitted from the nozzle blows the material that needs to be sorted aside. When the material falls next to the nozzle, the resulting debris and residue will enter the nozzle. Over time, this will cause the nozzle to become clogged, affecting the nozzle's air output efficiency. This solution does not provide high protection for the nozzle. Utility Model Content

[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] Figures 1-4 In one embodiment of this utility model, a multi-layer nozzle device for a color sorter includes a rectangular box 1. A plurality of nozzles 2 are arranged in a rectangular array on the surface of the rectangular box 1. A connecting plate 3 is fixedly connected to the back of the rectangular box 1, and connecting blocks 4 are fixedly connected to the two sides of the rectangular box 1 in an axially symmetrical manner. A protective component 5 is provided on the front of the rectangular box 1 to prevent material debris from entering the nozzles 2 and causing blockage during color sorting.

[0022] The specific problem addressed in this embodiment is: during material color sorting, when materials are shaken and enter the sorting path, the gas emitted from the nozzle blows the materials to be sorted aside, but when the materials fall near the nozzle, the resulting debris and residue enter the nozzle, causing long-term nozzle blockage and affecting the nozzle's air output efficiency. This utility model utilizes the protective component 5, with a filter screen 54 on the front of the housing 51, to directly block material debris generated during color sorting from entering the nozzle 2. Combined with the corresponding circular slots 6 on the surface of the housing 51 and the nozzle 2, it ensures smooth airflow while simultaneously intercepting debris. The filter screen uses a slot 52 and a rectangular plate 53 insertion structure, and is magnetically fixed by the first magnetic plate 531 and the second magnetic plate 532, enabling quick assembly and disassembly of the filter component, facilitating regular cleaning or replacement, and significantly reducing maintenance costs.

[0023] The protective component 5 includes a sleeve 51 disposed on the front of the rectangular box 1, and a slot 52 is provided on the top of the sleeve 51. A rectangular plate 53 is inserted into the slot 52, and a filter screen 54 is disposed inside the rectangular plate 53. In this specific embodiment, a first magnetic plate 531 is fixedly connected to both sides of the top of the rectangular plate 53, and a second magnetic plate 532 is magnetically connected to the bottom of the first magnetic plate 531. The second magnetic plate 532 is embedded in the top of the rectangular box 1 and located on both sides of the slot 52. The protective component 5 adopts a dual protective structure of a housing 51 and a filter interception net 54. The housing 51 externally isolates large particles of debris, while the filter interception net 54 internally intercepts fine dust, forming a staged filtration system. The nozzles 2 are arranged in a rectangular array on the surface of the rectangular box 1, precisely aligned with the round holes and slots 6 of the housing 51, avoiding obstruction of the airflow path, ensuring the uniformity and impact force of the color sorting airflow, and improving sorting accuracy. The magnetic attraction force of the first magnetic plate 531 and the second magnetic plate 532 is ≥15N, supporting the quick assembly and disassembly of the rectangular plate 53, improving the efficiency of filter cleaning. The magnetic contact surface is coated with an anti-corrosion coating, allowing for repeated use even in high temperature and high humidity environments.

[0024] In this specific embodiment, the surface of the sleeve 51 is provided with a rectangular array of circular slots 6, and the positions of the circular slots 6 correspond one-to-one with the mouthpiece 2. Both sides of the sleeve 51 are connected to the bottom of the connecting piece, and the inside of the connecting piece is rotatably connected to the threaded bolt 7. Both sides of one end of the threaded bolt 7 are provided with directional holes, and springs 71 are provided inside the directional holes. One end of the springs 71 is provided with steel balls 72. The surface of the connecting block 4 is provided with threaded holes 8, and the inside of the threaded holes 8 is threadedly connected to the surface of the threaded bolt 7. The two sides of the sleeve 51 are screwed and fixed to the threaded holes 8 of the connecting block 4 by the threaded bolts 7. The springs 71 and steel balls 72 built into the end of the threaded bolt 7 are deformed by pressure when tightened. The friction between the steel balls 72 and the inner wall of the threaded hole 8 forms a self-locking effect, preventing the threads from loosening due to equipment vibration, ensuring a tight connection between the sleeve 51 and the rectangular box 1, and improving the overall structural stability.

[0025] Working principle: Align the front of the housing 51 with the array position of the nozzles 2 on the rectangular housing 1, ensuring that the connecting pieces on both sides of the housing 51 are aligned with the connecting blocks 4 on both sides of the rectangular housing 1. Rotate the threaded bolt 7 so that the steel ball 72 at its end is pressed into the threaded hole 8 of the connecting block 4 under the elastic force of the spring 71. Tighten the thread to fix the housing 51. The friction self-locking function between the steel ball 72 and the inner wall of the threaded hole 8 can prevent loosening caused by vibration. The rectangular plate 53 is vertically inserted into the top of the housing 51 along the slot 52 until the first magnetic suction plate 531 and the second magnetic suction plate 532 embedded in the top of the rectangular housing 1 are magnetically attached, realizing the quick fixation of the rectangular plate 53. Confirm that the filter interception net 54 completely covers the inside of the housing 51 and that the round hole slot 6 corresponds one-to-one with the outlet of the nozzle 2, ensuring that the airflow channel is not misaligned. After starting the equipment, the nozzle 2 sprays high-pressure airflow outward through the round hole slot 6 of the housing 51. When materials enter the sorting area, the filter screen 54 blocks debris from entering the housing 51. The intercepted debris accumulates on the surface of the rectangular plate 53. The airflow maintains a clean output after passing through the filter screen. During the color sorting process, the intercepted debris remains on the filter screen 54. By manually lifting the top of the rectangular plate 53 upwards, overcoming the magnetic attraction of the first magnetic plate 531 and the second magnetic plate 532, the rectangular plate 53 can be pulled out of the slot 52. After removing the rectangular plate 53, the filter screen 54 can be directly cleaned or replaced without disassembling the entire structure of the housing 51.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
