Embodiment 1

[0021] A soybean meal crushing device 3, comprising a feeding device, a crushing device 3, a sorting device 4, a collecting device, and a tail dust treatment device; the feeding device includes a feeding hopper 1, a screw feeder 2, and the feeding hopper 1 is located on the ground, The outlet at the lower end of the hopper 1 is connected to the inlet of the screw feeder 2, the screw feeder 2 is arranged obliquely upward, and the outlet of the screw feeder 2 is located at the feed port of the crushing device 3; the upper part of the crushing device 3 feeds the material and the lower part discharges the material. The outside of the device 3 is provided with a soundproof cover; the sorting device 4 is conical, with the tip pointing down and opening, located above the feeding hopper 1, and the middle part of the sorting device 4 is provided with a feeding pipe, and the inlet of the feeding pipe is located in the pulverizing device 3 In the lower part, a fan is installed in the top ...

Embodiment 2

[0023] It is basically the same as Example 1, the difference is that the feeding pipe is U-shaped near the inlet, the inlet opening of the feeding pipe is upward, slightly larger than the size of the discharge part of the lower part of the crushing device 3, and is set on the discharge part of the crushing device 3, but mutually No contact; a high-pressure air pipe 8 is installed in the powder conveying channel 7, and several nozzles 9 are arranged on the high-pressure air pipe 8. The air outlet direction of the nozzles 9 is downward, and the distance between two adjacent nozzles 9 is transported according to the distance between the nozzles 9. The distance of passage outlet changes, and nozzle 9 is closer to delivery passage outlet, and the spacing of nozzle 9 is smaller, and the root number of high-pressure gas pipe 8 and the number of nozzle 9 are set according to the size and the length of delivery passage.

Embodiment 3

[0025] It is basically the same as Embodiment 2, except that a solenoid valve is installed between the high-pressure gas pipe 8 and the gas source, and the switching frequency of the solenoid valve is 1s on and 2 to 5s off; There is a dust outlet, the dust outlet is connected with a dust outlet pipe, and the other end of the dust outlet pipe is connected with the lower opening of the sorting device 4 .

Abstract

The invention relates to a soybean meal crushing device. The soybean meal crushing device comprises a feed device, a crushing device, a sorting device, a collecting device and a tail dust treatment device, wherein the feed device comprises a feed hopper and a screw feeder, the feed hopper is located on the ground, a discharge port of the lower end of the feed hopper is connected with an inlet of the screw feeder, the screw feeder is arranged upwards in an inclined mode, and an outlet of the screw feeder is located at a feed port of the crushing device; the upper part of the crushing device is used for feeding, and the lower part of the crushing device is used for discharging; the sorting device is tapered, the tip of the sorting device faces downwards, is open and is located above the feed hopper, a feed pipe is arranged in the middle of the sorting device, an inlet of the feed pipe is located in the lower part of the crushing device, a fan is installed in the top of the sorting device, an outlet is formed in the air outlet direction, and a powder conveying channel is installed at the outlet and is connected with the collecting device; the collecting device comprises a cyclone separator and an aggregate bin; and the tail dust treatment device is connected with an air outlet of the cyclone separator. The soybean meal crushing device has the advantages of full sealing of a production process, no dust leakage, safety, health and environmental friendliness.

Description

technical field [0001] The invention belongs to the field of production equipment for formaldehyde-free soybean meal glue, and in particular relates to a soybean meal crushing device. Background technique [0002] In the process of preparing formaldehyde-free soybean meal gum, it is necessary to crush the soybean meal to a suitable particle size to facilitate subsequent production and processing. Due to the production characteristics of the formaldehyde-free soybean meal glue, the crushing amount of the soybean meal powder is not large. However, the existing crushing device is either a separate grinder and a simple exhaust device, and the dust flies around during use, which pollutes the environment, endangers the health of employees, wastes soybean meal raw materials, and has potential safety hazards of combustible dust; or is a large-scale The complete set of equipment is not only expensive and occupies a large area, but also cannot be completely suitable for the production...
