Embodiment 1

[0020] Embodiment one: by Figure 1 to Figure 2 Provided, the negative pressure quantitative powdery material addition system includes a sequentially connected silo 2, a lower hopper 20, a feeder 12, a material receiver 14, a negative pressure fan 16 and a feeding pipeline 19, and the silo 2 is provided with Mesh screen 8, a powder quantifier is set in the feeder 12, a steel wire mesh 13 is set between the upper port of the receiver 14 and the feeder 12, and an air regulating device is set between the lower port and the negative pressure fan 16. Valve 15, the bottom of the feeder 12 is equipped with a connecting frame, and the side wall of the upper port of the receiver 14 is provided with a plurality of notches for the mounting of the connecting frame. This system is applied to powder materials. Therefore, starting from the silo , it is necessary to ensure that there will be no large pieces of material in the entire system. The powder metering device in the feeder 12 is set b...

Embodiment 2

[0021] Embodiment 2: On the basis of Embodiment 1, the inner wall of the silo 2 is provided with an installation frame and the ton bag cross arm 3 is movably installed through the installation frame, and the material ton bag is placed above the ton bag cross arm 3. Since the silo 2 is an opening Therefore, vibration motors cannot be used to assist blanking. A powder pushing frame 4 is arranged above the mesh screen 8 in the silo 2, and a horizontal guide rail 6 and a vertical guide rail 7 are arranged staggeredly below the powder pushing frame 4. The powder pushing frame 4 is a hollow frame structure and is driven by the hydraulic cylinder 5. By moving the powder pushing frame 4 back and forth, it can prevent material accumulation, avoid dust, and can push the large particle materials that are knotted together.

Embodiment 3

[0022] Embodiment Three: On the basis of the above-mentioned embodiments, a vibrating motor 10 and an air gun 11 are arranged on the lower hopper, and the vibrating motor 10 and the air gun 11 all have a vibration function, and the vibrating motor 10 is mainly used for auxiliary material blanking. However, relying on the vibration motor 10 alone is likely to cause materials to accumulate at the bottom of the lower hopper, and it is also easy to cause the materials to become solid. The setting of the air gun 11 cooperates with the vibration motor 10. Regular blowing can prevent the materials from becoming solid and avoid affecting the follow-up powder metering device. precision.

Abstract

The invention relates to the technical field of powdery material conveying, in particular to a negative-pressure quantitative powdery material adding system which solves the problem of uniform and quantitative feeding of powdery materials. The negative-pressure quantitative powdery material adding system comprises a material bin, a discharging hopper, a discharging device, a receiving device, a negative-pressure fan and a feeding pipeline which are sequentially connected. A mesh screen is arranged on the material bin. A powder batcher is arranged in the discharging device, a steel wire mesh is arranged between an upper end opening of the receiving device and the discharging device, an air adjusting valve is arranged between a lower end opening of the receiving device and the negative pressure fan, a connecting frame is arranged at the bottom of the discharging device, and a plurality of notches for installing the connecting frame are formed in the side wall of the upper end opening of the receiving device. Dispersed feeding of quantitative materials is achieved. And good development prospects are achieved in the technical field of powdery material conveying.

Description

technical field [0001] The invention relates to the technical field of powder material conveying, in particular to a negative pressure quantitative powder material adding system. Background technique [0002] In some special production processes, it is necessary to add a certain amount of powdered reducing agent or additives to the original materials, which requires the equipment to add quantitative materials in strict accordance with the standards, but the manual feeding method is too cumbersome and does not meet the automated production specifications. At this time There is a need for an automated system that can be continuously classified and transported according to the set amount. [0003] Moreover, the situation of adding reducing agents or additives is different from general material quantitative transportation. General material quantitative transportation requires more materials, does not require high accuracy, and does not require the dispersibility of materials, wh...
