Description

Rice mill with a sprayer

The utility model belong to the grain milling equipment and technology lead in, relate to a kind of spraying humidification rice mill.

Present situation according to available data and China's refine rice processing, limit humidification, limit pearling are generally adopted in external humidification husk rice, but its damping device generally send wet machine, water pump etc. to constitute by sprayer, spray wind, make technology, equipment complexity, involve great expense, just at present China's national situation does not satisfy the requirements widely-used.Domestic utilization humidification husk rice method still rests on the rice polishing stage, and is to polish after rice water, profit rice.Adopt compressed air atomization mostly because of adding wet tumbling, its atomizing effect is poor, and mist particle diameter is bigger, the grain of rice after causing processing grey irregular, simultaneously use air compressor do source of the gas to equipment use be with many unfavorable.

The purpose of this utility model is to provide a kind of simple in structure, adds that wet spray is even, droplet is little, atomizing effect is good, adopts common blower fan to make source of the gas, spraying humidification rice mill easy and simple to handle.

The purpose of this utility model realizes with the following methods.This spraying humidification rice mill, comprise support, drive, screen cloth, the hollow shaft that is connected with drive, be fixed on roller and propeller on the hollow shaft, end at hollow shaft has sprayer unit, this sprayer unit is by blower fan, airduct, liquor box, solution conduit, atomizing component constitutes, atomizing component comprises pneumatic the wheel, preceding fluted disc, rear tooth disk, the hollow little axle that joins with union elbow, the pneumatic wheel, preceding fluted disc, rear tooth disk is fixed on the bearing block by bearing pin, bearing block by bearing holder (housing, cover) on hollow little axle, union elbow and solution conduit are joined, and in the whitening chamber section into mist groove or hole are arranged on hollow shaft and the roller.Below in conjunction with accompanying drawing the utility model is further described in detail.

Fig. 1 the utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the structure enlarged drawing of atomizing component (26).

Among the figure: 1-hollow shaft, 2-roller, 3-propeller, 4-support, the 5-liquor box, 6, the 8-solution conduit, the 7-flowmeter, the 9-airduct, 10-blower fan, 11-feed nozzle, the 12-rice output mouth, 13,20, the 34-felt collar, 14-is pneumatic to take turns, the 15-bearing block, 16-helmet, 17-bearing, the 18-nut, the hollow little axle of 19-, 21-bearing pin, fluted disc before the 22-, 23-rear tooth disk, 24-deflection cone, the 25-union elbow, 26-atomizing component, 27-drive, 28-whitening chamber, 29-advance the mist groove, the 30-screen cloth, the little cavity volume of 31-, 32-mixing moisture, 33-water smoke.

Union elbow (25) has deflection cone (24) with hollow little axle (19) joint, and deflection cone (24) plays the effect of strengthening centrifugal atomizing, thereby controls the droplet size and the uniformity preferably.Between solution conduit (6) and (8), be connected with flowmeter (7), by the humidification amount of flowmeter (7) when controlling husk rice.Between preceding fluted disc (22) and the rear tooth disk (23) a little cavity volume (31) is set, has the pointed tooth more than tens on the fluted disc circumference successively, the pneumatic wheel is provided with more than two and angled wind wheel blade.Hollow little axle (19) is with being threaded in union elbow one end.Enter the front portion of mist groove (29) in roller (2).Roller can be that sand roller, iron roll, emery roll with iron ridge, hairbrush bar and polyamine fat bar or other materials are made.

During work, drive (27) rotates under the drive of motor, driving hollow shaft (1) and propeller (3) rotates, cereal enters propeller (3) from feed nozzle (11), blower fan (10) rotates, the pneumatic wheel (14) drives atomizing component (26) rotation at a high speed under wind drive, rotating speed generally can reach 10000 rev/mins, fluted disc (22) like this, little cavity volume (31) between the rear tooth disk (23) forms certain vacuum and produces suction, this moment water (or other solution) just from liquor box (5) through solution conduit (6,8), flowmeter (7), union elbow (25) and hollow little axle (19) enter little cavity volume (31), under the action of the centrifugal, water in the past, equally distributed numerous crowns are dished out on the backgear outer marginal circumference, form fine mist, the fogdrop diameter of Xing Chenging is little like this, be generally 45 microns, and uniformity height.Little droplet and air-flow synthesize wet gas current, wet gas current is offered on hollow shaft (1), roller (2) advances mist groove (29) or the hole enters whitening chamber (28), make the grain of rice in rotation is advanced constantly by even humidification, play moistening, emollescence, upset and slough moistening epidermal area, air-flow makes chaff skin, the gap of chaff powder between the grain of rice of taking off blow out whitening chamber from sieve aperture again simultaneously.Grind through the pearling device that the broken rice rate that is low, rice matter appearance surfaces is smooth, bright, pure white has evenly improved rice milling yield and rice grade, the superior rice that grinds after getting well flows out from rice output mouth (12).

The utility model adopts blower fan and atomizing component that water is atomized, and forms and mixes moisture, and the grain of rice is carried out even humidification, and wetting effect is good, and simple in structure, adopts common blower fan as the atomizing source of the gas, and is easy to operate.
