[0002] In the down treatment and processing industry, two-compartment separators are commonly used to separate down from raw materials. However, traditional two-compartment separators have some limitations in efficiency and quality: early equipment may have used simple screens or single-stage separation technology, which resulted in low separation efficiency and could not meet the needs of large-scale production; the screens of traditional equipment are easily clogged due to adhesion of down, requiring frequent cleaning and maintenance, which increases operating costs.

[0003] A Chinese patent discloses a grading cleaning device for a down sorting machine screen (publication number: CN 206538505U). The device comprises: a box body, characterized in that a roller brush and a fixed plate are arranged in sequence from top to bottom inside the box body, a transverse guide rail is arranged on the top of the box body, the roller brush is connected to the bottom of the transverse guide rail through a fixed frame, a thrust cylinder located outside the box body is arranged at one end of the fixed frame, driving the roller brush to move right along the transverse guide rail, two spaced longitudinal air pipes are arranged at the bottom of the fixed plate, and upper cylinders parallel to the air pipes are arranged on the outside of the air pipes, horizontal cylinders are symmetrically arranged on the outside of both sides of the box body, and the output end of the horizontal cylinder is connected to a water pipe, and one end of the water pipe is inserted into the box body from the outside of the box body. However, the grading cleaning device for the down sorting machine screen is complex in structure, the separation efficiency is not high, it cannot meet the needs of large-scale production, and the service life is short. Therefore, a negative pressure screen device for a high-pile two-compartment sorting machine is needed. Utility Model Content

This structural design can provide sufficient strength and durability while maintaining light weight and high-efficiency filtering functions.

[0007] Preferably, an electromagnetic vibrator is provided on the central inner wall of the negative pressure three-sided screen. The electromagnetic vibrator can help the screen to separate down more efficiently, reduce the adhesion of down on the screen through vibration, and improve the separation effect.

[0008] Preferably, the three-sided negative pressure screen is coated with an anti-stick coating, which reduces the adhesion of down on the screen, thereby improving screening efficiency and convenience of maintenance.

[0009] Preferably, the down separation partition is composed of a spacer wooden board and a spacer single covering board, and the spacer wooden board and the spacer single covering board are both made of glass fiber reinforced plastic, which provides good durability and sufficient structural strength to support the mechanical and environmental pressures that may be encountered during the down separation process.

[0010] Preferably, the spacer wooden board is associated with the top end of the spacer single covering board and is provided with a down separation arc opening, which is designed to optimize the flow and separation process of the down, and utilizes the shape of the arc opening to guide the down to pass through the separation area more effectively, thereby improving the separation efficiency.

[0020] In this embodiment, the negative pressure three-sided screen 1 is composed of a high-strength injection-molded bracket 16 and a multi-layer woven stainless steel wire mesh 15. This structural design can provide sufficient strength and durability while maintaining light weight and high-efficiency filtering functions.

[0021] In this embodiment, an electromagnetic vibrator 17 is provided on the central inner wall of the negative pressure three-sided screen 1. The electromagnetic vibrator 17 is a common product on the market and can be purchased directly. The electromagnetic vibrator 17 can help the screen to separate down more efficiently, reduce the adhesion of down on the screen through vibration, and improve the separation effect.

[0022] In this embodiment, the negative pressure three-sided screen 1 is coated with an anti-stick coating 14, which reduces the adhesion of down on the screen, thereby improving the screening efficiency and the convenience of maintenance.

[0023] In this embodiment, the down separation partition is composed of a spacer wooden board 5 and a spacer single covering board 6. The spacer wooden board 5 and the spacer single covering board 6 are both made of glass fiber reinforced plastic, which provides good durability and sufficient structural strength to support the mechanical and environmental pressures that may be encountered during the down separation process.

[0024] In this embodiment, the tops of the spacer wooden board 5 and the spacer single covering board 6 are associated and provided with down separation arcs, which are designed to optimize the flow and separation process of the down, and utilize the shape of the arcs to guide the down to pass through the separation area more effectively, thereby improving the separation efficiency.

[0025] The implementation principle of this embodiment is as follows: the raw material enters the first compartment box 2 through the hair inlet 4, and after being processed by the first compartment unloading shaft 9, the raw material is further removed of larger impurities through the first compartment hair outlet shaft 10 and the first compartment hair outlet 11, and the down below the first compartment hair outlet 11 is then sent to the second compartment box 3. The negative pressure three-sided screen 1 device adsorbs the down on the screen surface by the force generated by the negative pressure. Since the negative pressure has a wide action area, the down can be evenly processed on the three-sided screens. The electromagnetic vibrator 17 installed on the inner wall of the center of the screen generates micro-vibration to prevent the accumulation of down and avoid clogging of the screen. At the same time, the window 8 on the second compartment box 3 allows the operator to observe the internal processing situation. The separated down is collected through the second compartment hair outlet shaft 13, and finally sent out through the second compartment hair outlet 12 to complete the entire separation process.
