Description
Technical Field
The invention relates to a starch drying tail powder collecting device, which belongs to the field of primary processing machinery and environment-friendly machinery of agricultural products, in particular to a starch drying tail powder recycling device.
Background
In the current starch drying method, the airflow drying mode is the most common, the starch and hot air flow in parallel through a pipeline, water vapor is separated from the starch, the dried starch enters a cyclone separator, and flows out of the cyclone separator through an air-closing device. The cyclone separator is adopted to collect starch, the efficiency is high, the convenience is high, the powder collection rate is high, the cyclone separator is generally applied to starch drying, but the starch particles are 5-100 microns, the starch cannot be completely recovered by the cyclone separator, in addition, the design of part of the cyclone separator is not standard, and the influence of factors such as excessive drying exists, the powder leakage is easily caused during starch drying, so that the tail powder after the starch drying is necessarily recovered, the starch yield is improved, and the environmental pollution is reduced. The conventional starch drying tail powder recovery modes mainly comprise the following modes, firstly, a cyclone separator is adopted for further recovery, and a part of escaped fine tail starch particles can be further recovered by the mode, but the powder recovery rate is relatively low; secondly, a wet spraying mode is adopted for recycling, a spraying device or a water bath is additionally arranged at an air outlet of the dry tail powder, but the powder collection rate is limited because the starch is insoluble in water; and thirdly, the dust is removed by a cloth bag, but the starch is easy to be sticky when meeting water and easily blocks the cloth bag, so that the normal operation of the equipment is influenced, and the cloth bag dust removal mode is less applied to the recovery of the starch-dried tail powder.
Disclosure of Invention
The invention aims to provide a novel combined starch drying tail powder recovery device, which combines the advantages of a wet spraying method, a cloth bag dust removal method and a water bath method, so that the recovery rate of starch drying tail powder is improved.
The invention adopts the following technical scheme: the utility model provides a dry tail powder collecting device of starch, its by frame, casing, air intake, air outlet, spraying system, receive powder water tank, water supply system, receive parts such as powder sack and constitute, its characterized in that: the water sprayer is positioned at the top of the wind-water cone, the wind-water cone is a cone, the conical surface is densely distributed with vent holes, the bottom surface of the wind-water cone is fixed on the wind-water comb, the wind-water comb is densely distributed with vent holes, the lower end of the wind-water comb is connected with the powder collecting cloth bag through a flange, and the lower part of the powder collecting cloth bag is immersed in the powder collecting water tank.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic diagram of an appearance structure of a starch drying tail powder collecting device.
In the figure 1, an air inlet 1, an observation port 2, a water sprayer 3, an air-water cone 4, an air-water grate 5, an air-water outer guide ring 6, an air-water inner guide ring 7, a dust removal cloth bag seat 8, a dust removal cloth bag 9, a water inlet pipe 10, a circulating water pump 11, a powder dissolving pool 12, an overflow port 13, a discharge port 14, an outer shell 15, an air outlet 16, a circulating water pool 17 and a frame seat 18 are arranged.
Detailed Description
A starch dry tail powder collecting device is composed of a machine frame, a machine shell, an air inlet, an air outlet, a spraying system, a powder collecting water tank, a water supply system, a powder collecting cloth bag and the like, and is positioned on a machine frame seat 18, when the starch dry tail gas collecting device works, the collected dry tail gas enters the starch dry tail powder collecting device from the air inlet 1, the lower part of the air inlet 1 is provided with an observation opening 2, a circulating water pump 11 pumps water into a water sprayer 3 from a water inlet pipe 10, certain atomization is formed in the water sprayer 3 and meets the dry tail gas, starch particles in the tail gas are combined with water mist through a vent hole on an air water cone 4 and a vent hole on an air water grate 5, combined air flow enters a dust collecting cloth bag 9 through an air water outer guide ring 6 and an air water inner guide ring 7, the dust collecting cloth bag 9 is communicated with the air water cone 4 through a flange of a dust collecting cloth bag seat 8 to form an air flow channel, and water layer is formed by water flow flowing to the outer wall of the dust collecting cloth bag 9 through the air water grate 5, the device is characterized in that the device can block starch particles from escaping, simultaneously has a flushing effect on the dust removal cloth bag 9 to prevent blockage, a part of mixed air flow enters the powder dissolving pool 12 at the bottom in the dust removal cloth bag 9, is mixed with water solution in the powder dissolving pool 12, pure air escapes, and is discharged through the air outlet 16 together with escaping air passing through the dust removal cloth bag 9, the outer machine shell 15 is positioned above the powder dissolving pool 12 and below the air water grate 5 to form an air flow channel, the upper part of the outer machine shell is provided with the air outlet 16, the water solution flows into the circulating water pool 17 through the overflow port 13, and when the work is finished or the concentration of the solution is overhigh, the discharge port 14 at the lower part is opened to replace fresh water.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
