Abstract
The utility model discloses a device for recovering residual modified starch in an induced draft device and relates to a collecting device of a centrifugal spray tower, which is communicated with the induced draft device of the centrifugal spray tower. The recovery device comprises a funnel-shaped induced draft pipe and a recovery tower, wherein the upper opening end of the funnel-shaped induced draft pipe is communicated with an air outlet pipeline of the induced draft device, and the lower opening end is communicated with the recovery tower; a cylinder capable of recovering powders in air is arranged in the recovery tower; the upper end of the cylinder is communicated with the lower opening end of the funnel-shaped induced draft pipe, and the lower end of the cylinder is provided with a recovery port for collecting residual modified starch powders in gas; and a multi-layer filter mesh is arranged in the cylinder, and the gas with the residual modified starch powders is filtered by the filter mesh layer by layer so as to collect the modified starch powders. The device has the benefits of being simple in structure and obvious in using effect, being capable of completely collecting the residual modified starch powders in the exhausted gas so as to achieve emission without any dust, avoiding affecting the air and simultaneously and greatly improving the yield of the modified starch.
Description
Technical field
The utility model relates to the centrifugal spray tower gathering-device, specifically is a kind of device that is used for reclaiming the residual converted starch of blower unit.
Background technology
For the performance of improving starch, enlarge its range of application, utilize physics, chemistry or enzymatic treatment, on starch molecule, introduce new functional group or change starch molecule size and starch granules character, thereby change the natural characteristic (as: gelatinization point, thermoviscosity and stability thereof, freeze-thaw stability, gel force, film forming, the transparency etc.) of starch, make it be more suitable for requirement in certain application.This through secondary operations, the starch that changes character is referred to as converted starch.And this converted starch is the novel raw material of many industrial departments.For example textile industry forms a kind of new free from environmental pollution, harmless slurry with converted starch substituted ethylene class slurry.As papermaking and paper product industries, can improve paper inherence and surface quality, change printing performance etc. with converted starch as various auxiliary agents, sizing agent, bonding agent, therefore become at present the third-largest raw material of paper industry.
At present, the production technology of common converted starch is unreasonable, and its whipping process all is manually-operated mostly, therefore heat also insufficiently, cause yielding poorly, and the converted starch of producing is of low quality, purity is not high, has hindered the raising of converted starch added value, has limited the purposes of converted starch.
The starch solution that finishes with batching be injected into self priming pump on the centrifugal spray tower the jar in stand-by, guaranteeing under 65 ℃ of temperature conditions of starch solution, slowly join in the supercentrifuge of centrifugal spray tower with funnel starch solution, vapor (steam) temperature remains on more than 150 ℃ in the centrifugal spray tower simultaneously, make and concentrate good starch solution formation atomizing, efflorescence under the double action of process high speed rotary centrifuge and high-temperature gas, be powdery in falling within the bottom of the tower at last, produce high-intensity converted starch finished product.Owing to charged into gas in the centrifugal spray tower, and by blower unit wind direction is formed circulation and discharge, in outside air draft process, the particle of converted starch is very tiny, therefore part can be along with blower unit also is discharged from, not only cause waste, and be discharged to formation particles suspended in back in the air, also influential to environment.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of device that is used for reclaiming the residual converted starch of blower unit.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of device that is used for reclaiming the residual converted starch of blower unit, be connected with the blower unit of centrifugal spray tower, it is characterized in that: described retracting device comprises infundibulate induced duct and recovery tower, the upper open end of described infundibulate induced duct and the wind pipe of blower unit are connected, and lower open end is communicated with recovery tower.
The upper open end diameter of described infundibulate induced duct is greater than the diameter of lower open end.
Be one can reclaim the cylinder of powder in the air in the described recovery tower, the lower open end of upper end and described infundibulate induced duct is connected, and the lower end is provided with one and reclaims mouthful, is used for collecting reclaiming the converted starch powder that remains in gas.
Be provided with the multiple filtration net in described cylinder, the residual gas that the converted starch powder is arranged gets up the converted starch powder collection through after the filtration layer by layer of screen pack.
The beneficial effects of the utility model are simple in structure, it is obvious to use effect, can reach the discharging of no any dust with remaining in whole the collecting of converted starch powder of discharging in the gas, can not have any impact to air, improve the output of converted starch simultaneously greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of device that is used for reclaiming the residual converted starch of blower unit, be communicated in the blower unit of centrifugal spray tower, retracting device 1 comprises infundibulate induced duct 11 and recovery tower 12, the upper open end of infundibulate induced duct 11 and the wind pipe of blower unit are connected, and lower open end is communicated with recovery tower 12.Wherein the upper open end diameter of infundibulate induced duct 11 is greater than the diameter of lower open end.
Be one can reclaim the cylinder 121 of powder in the air in the recovery tower 12, the lower open end of upper end and infundibulate induced duct 11 is connected, and the lower end is shaped on reclaims mouthfuls 122, reclaims mouthfuls 122 and is used for collecting and reclaims the converted starch powder that remains in gas.Three layer filtration net 123 is installed in cylinder 121, and the residual gas that the converted starch powder is arranged all gets up the converted starch powder collection through after the filtration layer by layer of screen pack 123.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
