[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] See Figure 1-3As shown, an industrial material precision delivery device includes an outer mounting frame 2. Rectangular outer protective plates 4 are flipped and connected to both sides of the front of the outer mounting frame 2. A horizontally arranged storage bin 1 is fixedly connected to the top of the mounting frame 2. Vertical feeding components 3 are provided on both sides of the bottom of the storage bin 1. An H-shaped protruding partition 5 is fixedly connected to the center of the front of the mounting frame 2. A first limiting frame 6 and a second limiting frame 7 are fixedly connected to the upper and lower sides of the partition 5, respectively. The feeding component 3 includes a first discharge bin 8, a feeding pipe 9, and a distribution bin 10 connected sequentially from top to bottom. A second discharge bin 11 is arranged around the outside of the distribution bin 10. A distribution pipe 12 is connected to both sides of the bottom of the second discharge bin 11. A stirring fan 13 is arranged in the center of the interior of the distribution bin 10. A vibrating screen 14 and an airflow sorting plate 15 are arranged on both sides and the bottom of the interior of the distribution bin 10, respectively.

[0030] In this embodiment of the utility model, the first limiting frame 6 and the second limiting frame 7 are both arranged horizontally, located at the upper and lower sections of the feeding pipe 9, respectively. The surface of the first limiting frame 6 is provided with a set of arc-shaped support seats, and the surface of the second limiting frame 7 is provided with two sets of arc-shaped support seats. The first limiting frame 6 achieves the effect of limiting and fixing the feeding pipe 9 from the upper section, and the second limiting frame 7 achieves the effect of limiting and fixing the feeding pipe 9 and the distributing pipe 12 from the lower section.

[0031] An arc-shaped guide seat is centrally located inside the storage silo 1. Two sets of first discharge silos 8 are connected to each other on their bottom sides. The first discharge silos 8 are vertically arranged in a conical shape. A pneumatic butterfly valve is installed at the bottom of each first discharge silo 8. The feeding pipe 9 and the first discharge silos 8 are connected by a flange seal, with a metal spiral wound gasket at the flange connection. The distribution silo 10 is generally triangular in shape, with two concave arc-shaped sides. Radial ribs are installed in the concave arc-shaped areas. A vibrating screen 14 is located on the surface of the concave arc-shaped areas on both sides of the distribution silo 10. The vibrating screen 14 is a single-layer stainless steel screen (aperture d + 0.5 mm), with an amplitude of 1.5 mm ± 0.1 (fixed value) and a vibration direction of 15°. The airflow separation plate 15 is convex in an arc shape and is located below the vibrating screens 14 on both sides. The device is positioned as an inclined airflow sorting plate with micropores on its surface and an inclination angle of 30°. A pulsed airflow (0.2-0.5MPa) with a constant pulse pressure of 0.3MPa is introduced at the bottom. A rectangular elastic steel frame is provided between the vibrating screen 14 and the distribution bin 10, and a lip-shaped silicone sealing ring and a magnetic lock are provided. The surface of the airflow sorting plate 15 is provided with four sets of independent fins, which are distributed at equal angles along the edge of the arc-shaped plate to prevent particle retention. Through the inclination vibration of the vibrating screen 14, combined with the magnetic quick-release mechanism, the threshold particle screening rate is 100%, and the anti-clogging effect is achieved. The silicone lip ring provides a sealing and leak-proof effect. The airflow sorting plate greatly improves the critical particle adsorption rate. The micropore chamfered anti-clogging design on the surface, together with the guide fins, enhances the sorting accuracy.

[0032] The guide fins are inclined towards the geometric center of the sorting plate, causing the airflow field to converge centripetally and effectively avoiding turbulence. The inclination angle is 35°±1°, and their length is set to one-quarter of the arc length of the sorting plate 15 to ensure uniform airflow throughout the circumference. A nano-coating is applied to their surface. The agitator fan 13 has three sets of arc-shaped blades, with a drive motor mounted at its outer end. A fully enclosed grille cover is located on the front. The blades of the agitator fan 13 are fitted with tungsten steel wear-resistant cutting edges. A conical flow stabilizer with a cone inclination angle of less than 60° is located at the top of the agitator fan 13 to ensure 100% self-slippage of particles, thus eliminating particle suspension caused by eddies. The diameter of the opening at the top of the cone is... With an opening ratio of 18%, it is capable of pre-screening fine particles, while the diameter of the conical opening is... The device features evenly distributed holes in an equilateral triangular array with a hole center distance of 5mm and an opening rate of 15%. The conical flow stabilizer within the hole eliminates eddies and reduces particle suspension time, while also pre-screening fine particles. It guides the mainstream particles to the screening area, and the guide fins cause the airflow to converge centripetally, reducing the critical particle misscreening rate. This effectively reduces the amount of material accumulated at the plate edge and lowers airflow energy consumption.

[0033] The material flow falls onto the conical flow stabilizer above the mixing fan 13. The material impacts the top of the cone vertically. Fine particles fall directly through the hole at the top of the flow stabilizer cone, while the mainstream particles slide along the 60° cone surface to the edge and are screened out by the vibrating screen 14. Another part of the mainstream particles pass through the airflow separation plate 15, and critical particles are adsorbed.

[0034] The second discharge bin 11 is a rectangular bin surrounding the outer side of the distribution bin 10. The end of the second discharge bin 11 that connects with the distribution pipe 12 is a trapezoidal outlet. The distribution pipe 12 is Y-shaped, with the top section configured as a double channel that connects to the bottom of the second discharge bin 11 and is arc-shaped and convex. The bottom section of the distribution pipe 12 is S-shaped and wound around the bottom surface of the feeding pipe 9, with a neoprene rubber shock-absorbing ring between it and the surface of the feeding pipe 9. The bottom end of the distribution pipe 12 is a metal corrugated pipe with a universal joint. The S-shaped winding of the distribution pipe 12 with the neoprene rubber ring and the metal corrugated pipe can effectively reduce the vibration transmission rate, increase the bending life, and achieve precise delivery with the universal joint.

[0035] The material distribution bin 10 with built-in radial ribs has a reinforced arc-shaped concave area, which effectively improves its resistance to impact deformation and eliminates stress concentration. The magnetic locking mechanism enables quick-release of the screen, effectively reducing maintenance time. The fully enclosed grid cover of the stirring fan 13 isolates the rotating parts.

[0036] During the pre-screening stage, ultrafine particles directly enter the feed pipe 9 outlet through the cone top hole, bypassing the main screen section. Then, in the main screening stage, large particles slide along the cone surface into the vibrating screen 14 and are ejected to the second discharge bin 11. Subsequently, critical particles are captured, adsorbed by the pulsed airflow, and fall after converging towards the center through the guide fins. Finally, in the shock absorption and distribution stage, large particles are buffered by the vibration of the distribution pipe 12 and output by the universal angle adjustment of the metal corrugated pipe at the bottom.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
