Abstract

The utility model relates to a flotation machine used for separating protein granules and starch granules of rough milk of starch in starch industry, which is composed of a separation chamber, a mixing drum, a stirrer, etc., wherein, the mixing drum is divided into an upper and a lower layers by a baffle plate, and the upper layer is a mixing chamber provided with the stirrer; the lower layer is a feeding chamber filled with glass beads, and the mixing drum is installed in the separation chamber. The utility model has the advantage of good air flotation effect, and can be used for the rough milk of starch of high starch content. Over 70 percents of protein of milk of starch can be separated, which ensures that a spraying nozzle of a separator is not blocked in later processes and a rotational flow tube is expedite.

Description

A kind of flotation device

The utility model relates to a kind of flotation device, is the device that in the starch industry protein body in the coarse starch milk is separated with starch granules.

Existing starch producing technology is coarse starch milk directly to be sent into seperator albumen is separated with starch, because protein content is higher in the coarse starch milk, causes the seperator nozzle often to stop up, and cyclone pipe is not smooth, needs frequent disassembly, cleaning aborning.

The purpose of this utility model is to provide a kind of flotation device at the problems referred to above, and this flotation device is applied to the seperator preceding working procedure, separablely goes out that contained protein reaches more than 70% in the coarse starch milk.

Flotation device of the present utility model adopts the air supporting principle, it is characterized in that comprising separation chamber, mixing drum and agitator.Described mixing drum is divided into upper and lower two-layer by dividing plate with holes, the upper strata is a mixing chamber, and chamber interior walls has longitudinal baffle, the center, chamber is provided with agitator, and lower floor is the taper feed space, and screen is arranged at the feed space bottom, indoor filling glass ball, the feed space lower end is communicated with feed pipe.Mixing drum is installed in the separation chamber, and top, separation chamber connects overflow pipe, and the lower end is a discharging opening.The pressure that relies on pump to produce, the high speed coarse starch milk and the air that are penetrated by water-jet pipe nozzle become the feed space that the air water mixed liquor enters the flotation device mixing drum, mixed liquor spreads in the glass marble of feed space, increased the contact area of air and material, form bubble liquid and enter mixing chamber equably, under the effect of agitator, form bubble size foam solution more uniformly, to guarantee air flotation effect, foam solution enters the separation chamber, heavy starch granules sinks to the bottom, and protein body is then discharged by overflow pipe.

The utility model has the advantages that and be used for the high coarse starch milk of content of starch, separablely go out that contained protein reaches more than 70% in the starch milk, guaranteed that the seperator nozzle in the later process does not stop up, cyclone pipe is unimpeded, maintenance time and expense have been reduced, compress the usage quantity of seperator in the whole technical process simultaneously, reduced water consumption, saved the energy.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a mixing drum structural representation of the present utility model.

Embodiment: referring to Fig. 1,2, flotation device of the present utility model comprises separation chamber 1, mixing drum 2 and agitator 3.Separation chamber 1 is made by steel plate, and the upper end is connected with overflow pipe 5, and the lower end is taper, and the bottom is a discharging opening 6.Mixing drum 2 materials are stainless steel, be separated into upper and lower two-layerly by dividing plate with holes 9, the upper strata is a cylinder mixing chamber 7, and the center, chamber is equipped with agitator 3, agitator 3 is driven by drive unit 4, rotating speed is 300 rev/mins, and mixing chamber 7 inwalls evenly are provided with 4 longitudinal baffles 8, the eddy current that produces when stirring to alleviate, the lower floor of mixing drum 2 is conical feed spaces 11, feed space 11 bottoms are provided with screen 12, indoor filling glass ball 10, and feed space 11 lower ends are communicated with feed pipe 14.Mixing drum 2 is installed in 1 inside, separation chamber.13 is drain valve among Fig. 2.
