Description

Wheat washer

Technical field

The utility model belongs to wheat flour milling processing equipment field, and what relate to is the preceding wheat washer of a kind of abrasive dust.

Background technology

Should remove the dirt in the awn of wheat, fringe shell, wheat surface and the ventral groove before the wheat abrasive dust and be mixed in foreign material such as silt in the wheat, also need moistening wheat surface enter the abrasive dust operation.Therefore, it is an indispensable step that wheat is cleaned, if adopt water-washing method also can reduce the persticide residue of wheat.

The wheat chamber of washing of existing wheat washer all is a kind of horizontal tank, charging aperture is positioned at an end of washing tank upper edge, wheat chamber, conveying auger is installed in the tank, and dewatering station's vertical connection is arranged on washes the top of wheat chamber with respect to charging aperture far-end one side, and discharging opening is positioned at the upper end of dewatering station.Wheat is immersed in the flowing water of tank after entering and washing the wheat chamber, and from just entering the bottom of dewatering station after an end of tank is shifted to the other end, the discharging opening that the rotation whipping of beater rotor is promoted to the upper end in dewatering station is discharged then under the rotation of conveying auger promotes.There is following deficiency in the wheat washer of this structure: 1. wheat is fully immersed in the water and washs, and makes its water absorption excessive and increase the required energy consumption of dehydration unavoidably; 2. wash the indoor conveying auger of wheat rotary work in water, resistance is big, the power consumption height; 3. the water in the tank is flowing water, and 1 ton of wheat of every cleaning gets 1 ton of water, and not only water consumption is big, and quantity of wastewater effluent is also big.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that existing wheat washer exists, and a kind of low energy consumption, high efficiency wheat washer are provided.

The technical scheme that realizes above-mentioned purpose is: a kind of wheat washer, comprise that grooved washes the wheat chamber, washes the indoor conveying auger of wheat and dewatering station and engine, it is characterized in that: described to wash wheat indoor, crossheading is equipped with a sparge pipe directly over the conveying auger, and the downward water jet of former and later two spouts is arranged on this sparge pipe; The bottom land of washing the wheat chamber has sewage draining exit two intervals, that have screen cloth and a blanking port, and described blanking port is at the remote location with respect to charging aperture; The main body of described dewatering station is a screen drum, dewatering station's level is installed on the frame of washing below, wheat chamber, and the connection corresponding up and down with the blanking port of washing the wheat chamber of the feeding mouth of one end upper edge is equipped with re-packing of helical arrangement in the dewatering station, discharging opening is positioned at the below of dewatering station's other end.

Wheat is admitted to the spray of washing behind the wheat chamber earlier through preceding water jet ejection water from charging aperture, advanced by the rotation of auger and move ahead, in the progradation of auger, the phase mutual friction takes place between wheat, realize the omnidistance action of cleaning, when wheat is pulled to when washing rear end, wheat chamber, again through the flushing of the water of water jet ejection later, the wheat of this moment is clean by washing, immediately the dewatering station below blanking port falls into.In the process of spray washing, sewage and silt are successively discharged from the sewage draining exit at two intervals of bottom land.In dewatering station, at a high speed the attachment and the moisture that re-pack the wheat surface of rotation throw away from sieve aperture, and wheat is discharged from discharging opening.

A kind of improvement as above-mentioned technology: the front end at sparge pipe is equipped with a discharge monitor controller.Can monitor and control the injection flow rate of sparge pipe by this device, guarantee that requirement and the wheat wetting moisture of cleaning wheat institute water requirement reach proper content.

Another improvement as above-mentioned technology: a regularly spray water device is installed above dewatering station.This timing spray water device can carry out the timing hydroblasting to the dehydration screen drum automatically, and is unimpeded all the time to guarantee the sieve aperture on the screen drum, thereby the dehydration that can guarantee wheat is in optimum state.

Another kind as above-mentioned technology improves: the clutch end at engine is equipped with arrangements for speed regulation.By these arrangements for speed regulation, can make the rotating speed of conveying auger satisfy wheat wash wheat indoor the water time; The centrifugal force that rotary speed produced that re-packs in the screen drum satisfies the dehydration requirement of wheat, and makes the wheat after the dehydration reach the wheat wetting water-content indicator.

Advantage of the present utility model is: 1. the soaking and water washing of wheat can be changed into the segmentation water-sprinkling flushing, save water significantly, whenever wash 1 ton of wheat and only use 0.2-0.3 ton water, also reduce blowdown flow rate simultaneously; 2. conveying auger does not soak the resistance of water in rotary course, and the dehydration screen drum is horizontally disposed with, and does not need wheat is upwards promoted, and has reduced power consumption; 3. make the wheat water absorption suitable, avoided energy consumption extra in the dehydration.
