Embodiment 1

[0044] Embodiment 1: as figure 1 , figure 2As shown, an air separation process that improves the air separation efficiency and reduces the material crushing rate, the air flow wind passes through the wind mesh belt 8 from below and then enters the air separation warehouse 23, the wind mesh belt 8 is a braided mesh belt, The size of the wind mesh is 1.3mm*1.6mm; the mesh belt-type wind-passing mesh belt 8 is used instead of the traditional steel punching mesh plate, thereby canceling the chain-type transmission mode, and the belt-type transmission replaces the chain transmission, which reduces wind resistance and improves wind resistance. field uniformity, improve the accuracy of air distribution, reduce noise, reduce material clamping and return, and adopt roller 6-type transmission, which has the effect of energy saving and low noise, and achieves the purpose of energy saving and environmental protection; the material passes through the air lock from the feed port 2 The fee...

Embodiment 2

[0046] Embodiment 2: as figure 2 , Figure 4 , Image 6 As shown, an air separation device for improving the efficiency of air separation and reducing the crushing rate of materials comprises an air separation body 1, a feed port 2, and a heavy material discharge port 3 placed at the bottom of the air separation body 1, which is located at the air separation body 1. The light material discharge port 4 above the sub-body 1, the filter screen device is located below the feed port 2 and placed in the lower part of the air sub-body 1, and the air inlet 5 is located at the bottom of the air sub-body 1 and is located under the filter screen device. The filter screen device includes a drum 6 placed at both ends, a transmission motor 7 for providing power, a wind mesh belt 8 for passing the wind filter material, the wind mesh belt 8 is set on the roller 6, and the wind mesh belt 8 is placed below Deviation correction device 9; the light material outlet 4 is connected to the flexibl...

Embodiment 3

[0051] Embodiment 3: as Figure 7 As shown, the device is that at least two groups of devices are connected and combined through a combination system. Pipe 36, qualified material discharge vibrating screen 37;

[0052] Wherein: the flotation blower 32 is installed on the outer bottom of the air separation body 1 and connected to the air inlet 5, and the negative pressure suction pipe 15 is divided into a flotation negative pressure air pipe 35 and a feeding negative pressure air pipe 36 at both ends of the outer cover 10 , the flotation negative pressure air duct 35 is connected to the flotation fan 32, the feeding negative pressure air duct 36 is connected to the feeding fan 33, the qualified material discharge vibrating screen 37 is arranged under the flexible blanking equipment, and the heavy material discharge port 3 Connected to the feeding positive pressure air pipe 34, the bottom of the feeding fan 33 is connected to the flexible blanking device placed on the feed port...

Abstract

The invention provides an air separation process and device for improving air separation efficiency and reducing the damage ratio of materials and an air separation system with simple structure, high air separation efficiency and accuracy and low damage ratio. According to the invention, the traditional discharging form is changed into a mesh-belt type structure, and a mounting form is a vertical downward side discharging form; a screen cylinder of a feeder is replaced to realize material-device separation, so that the wind resistance is reduced, and the homogeneousness of a wind field is improved; a filter material mesh belt is used for conveying and discharging, so that the damage and the folding of tobacco leaves caused by squeezing of a cross gate of the feeder can be effectively reduced; the operating speed of the mesh belt is about 1.5m/s, a rectification detection mechanism and a rectification mechanism are arranged in the operation of the mesh belt, so that the rotation speed of the mesh belt can be reduced due to the form, the discharge is increased, and the operating reliability is enhanced; and an air outlet pipe is provided with an air distribution valve, so that the homogeneousness of a wind field for air separation is ensured, no damage exists when in discharging, and a flexible blanking function is realized. Therefore, the air separation quality and the air separation efficiency are effectively improved, and the considerable discharge quality with low damage ratio is realized.

Description

technical field [0001] The invention relates to an online process equipment technology for leaf threshing air separation and blanking equipment in the tobacco industry or light material industry, specifically an air separation process and device for improving air separation efficiency and reducing material crushing rate. Background technique [0002] The leaf threshing and air separation equipment is one of the most important hosts in the rebaking process. In the early 1990s, the first threshing and rebaking production line undertaken by Yuxi Cigarette Factory in Yunnan Province technically introduced the American rebaking process. The layout completely replaces the traditional hanging pole re-baking and subverts the re-baking process. After more than 20 years of digestion and absorption and multiple technical improvements, there is no obvious reform and innovation in the leaf-threshing air separation technology. The traditional air separation box mechanism adopts steel punch...
