Problems solved by technology

However, the equipment has uneven pressing of distiller's grains, the pressing effect is not ideal, and it is very inconvenient to clean the extruded water. In addition, the equipment cannot achieve continuous pressing work, and the pressing efficiency is low. Therefore, the structure of the pressing equipment needs to be further improved.

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as Figure 1 to Figure 15 As shown, the pollution-free and environmentally friendly distiller's grains processing method of the present embodiment comprises the following steps:

[0036] 1. Input the distiller's grains into the barrel cavity of the distiller's grains processing device for extrusion;

[0037] 2. The twin-screws 2 in the distiller's grain processing device extrude the distiller's grains and transport the distiller's grains to the discharge port 12 of the distiller's grains processing device. The exhaust hole 13 of the distiller's grains processing device is discharged;

[0038]3. The suction device absorbs the steam and volatilized alcohol discharged from the exhaust hole 13 and recycles it;

[0039] 4. The dehydrated distiller's grains are transported from the discharge port 12 to the dehydration residue collecti...

Abstract

The invention discloses a pollution-free and environmentally friendly vinasse treatment method. The method is characterized by comprising the following steps that step one, vinasse is conveyed into aninner cavity of a cylinder of a vinasse treating device for extrusion; step two, a twin screw in the vinasse treating device extrudes the vinasse and conveys the vinasse to a discharging outlet of the vinasse treating device, the vinasse treating device extrudes and heats the vinasse synchronously, and in the extruding process, the generated steam and the volatilized ethyl alcohol are exhausted from the a gas exhausting hole of the vinasse treating device; step three, a gas sucking device absorbs and recovers the exhausted steam and the volatilized ethyl alcohol; step four, the dehydrated vinasse is conveyed to a dehydrated residue collecting device from the discharging outlet for recycling. The method has the advantages that the extruding effect is good; moisture and ethyl alcohol whichare extruded from the vinasse entering the cylinder only can be exhausted from openings in the two ends of the cylinder or the discharging outlet, or the moisture and the ethyl alcohol are heated to become gases so as to be exhausted from the gas exhausting hole, therefore it is only required that collecting device are placed at corresponding positions, the moisture and the ethyl alcohol can be prevented from spilling, or waste gas can be prevented from being exhausted directly, and the method is green, environmentally friendly and pollution-free.

Description

technical field [0001] The invention relates to a distiller's grain waste treatment and recovery technology, in particular to a pollution-free and environment-friendly distiller's grain treatment method. Background technique [0002] There is a Chinese invention patent application with the application number CN201310349259.2 titled "A Distiller's Grains Pressing Equipment" which discloses a distiller's grains pressing equipment. A hydraulic cylinder is installed in the frame of the equipment, and an oil inlet is arranged on the hydraulic cylinder. And the oil return port, the lower end of the hydraulic cylinder is connected with a pressure plate, and the bottom of the hydraulic cylinder is provided with a pressure cylinder for containing distiller’s grains. The pressure plate enters the pressure cylinder to squeeze the distiller’s grains under the action of the hydraulic cylinder. There is a water outlet. The beneficial technical effects of this invention are: using a hydra...
