Cottonseed protein weary gas prebake tower
The utility model relates to a kind of drying plant, is specially a kind of Multilayer disc type drying tower utilizing the weary gas of waste heat to carry out drying materials.
In the technique that extraction produces cottonseed oil and cottonseed protein, with the grease in organic solvent lixiviate cottonseed, realize cold-press and produce, more traditional hot moulding technique can avoid cottonseed kernel protein heated denaturalization, and dephenolize can obtain cotton protein further.In this process, the cotton protein after dephenolize needs to drain through extruding, dry to remove organic solvent wherein and methyl alcohol, and realizes the recycling of organic solvent and methyl alcohol.Cotton protein baking stage not only needs to consume a large amount of heat energy, and drying efficiency directly decides system production efficiency.
For ensureing that cottonseed protein because being heated too high, sex change does not occur at baking stage, it is indirectly conduct Multilayer disc type drying plant that de-equipment is steamed in conventional oven dry, from top to bottom successively dries.For example a kind of indirect heating precipatation drying machine for cottonseed dregs disclosed in Chinese patent CN2802398, comprise the vertical shaft of housing, charging aperture, discharging opening, casing center, fixing tray, the cloth claw leaf etc. be connected with vertical shaft, heat-carrying pipe is connected with in dryer housing, there is heat-carrying agent in heat-carrying pipe, produce last drying and desolventizing operation for cottonseed protein.But enter in the process of collected overhead mouth through steaming the de-solvent gas be separated in rising, can occur with advance in the phenomenon that again contacts of material, thus impact is dried and is steamed de-effect, and affects the quality of cotton protein.Steam de-effect and cotton protein quality for improving to dry, people have carried out Curve guide impeller to drying plant, to the upper and lower interval Fraction collection of the degassed body of steaming.For example a kind of albumen disclosed in Chinese patent CN202924987U is without sex change evapo-separated machine, the free solvent in the dehumidification dregs of rice is steamed by first, second and third pre-disk stripping, free solvent gas is directly discharged through exhaust hole, afterwards material by direct vapour layer steam in the dehumidification dregs of rice in conjunction with solvent, and separately establish steam guiding tube to be discharged through exhaust hole by the mixed steam of the solvent gas produced at direct vapour layer and water vapour, the free solvent in the wet dregs of rice can be made like this and steam de-collection in conjunction with solvent respectively by different passages.This equipment two sections stoving process is different, complex structure inconvenience control and regulation, and its second stage adopts direct hot vapour to dry, and easily causes albumen to cross thermal denaturation.Dividing plate and doffer is provided with in the tank body of the one disc type dryer of a kind of point of concentration recycling design disclosed in similar Chinese patent CN103063002A, tank body is divided into upper tank body and lower tank by described dividing plate, by dividing plate and wind stopping device device, upper tank body and lower tank are divided into two independently spaces, methanol content in gas is out dried high in upper tank body, dry methanol content in gas out in lower tank low, so just can obtain two kinds of liquid of variable concentrations.Above-mentioned several art methods, dries although achieve substep and collects respectively, and not only device structure is complicated for it, working cell independence is not strong, require that the material before drying is containing wetting below 40%, and consume a large amount of heat energy, its oven dry operating efficiency is lower in addition.
Utility model content
The purpose of this utility model is to provide the cottonseed protein drying plant and technique that a kind of operating efficiency is high, thermal energy consumption is few, dries quantity is high.
This cottonseed protein weary gas prebake tower, comprise shell, air inlet pipe, escape pipe, charging aperture, discharging opening, charging tray, described charging tray is horizontal hollow disk, is connected with shell by support, and its left and right sides is connected with escape pipe with weary gas air inlet pipe respectively, and charging tray central openings establishes rotating shaft, rotating shaft is not connected with charging tray, and reductor is established in one end of rotating shaft, and circular boop is established in position rotating shaft is positioned at above charging tray, circular boop level connection joint is with the pivoted arm of multiple scraper plate, and cover top portion arranges gas collection mouth.The combination of described charging tray, circular boop and pivoted arm has many groups, and layering is evenly distributed from top to bottom; And the charging tray radius of odd-level is greater than even level charging tray, and offers blanking hole in the centre of the charging tray of odd-level, and its scraper plate becomes horizontal up time angle that material to be gone forward one by one movement to central authorities with pivoted arm.And the scraper plate of even level becomes level inverse time angle to make material go forward one by one laterally movement with pivoted arm.The charging tray of the last one deck in bottom is closely connected with shell, and sets out material mouth in its side.And the pivoted arm on every one deck has many groups and is uniformly distributed in same level.
The utility model is used for the prebake before cotton protein drying procedure, cotton protein is not made to cross thermal denaturation at guarantee baking stage, under improving the prerequisite of protein quality, not only effectively make use of the weary gas of waste heat of production system, achieve secondary to utilize, saving heat energy, and the drying efficiency substantially increasing original system, can make original oven dry workshop section production efficiency improve more than 40%.And baking stage material is promoted greatly containing humidity load buffer capacity.The cotton protein produced is bright in colour, and quality significantly improves.

detailed description of the invention
As Fig. 1, Fig. 2, Fig. 3, cottonseed protein weary gas prebake tower comprises shell 1, air inlet pipe 2, escape pipe 4, charging aperture 5, discharging opening 14.Dry level in the present embodiment and have 18 layers, and the charging tray 8a radius of odd-level is greater than even level charging tray 8b, and offer blanking hole 12 in the centre of the charging tray 8a of odd-level, and the horizontal up time angle of its scraper plate 7a is 30
0; And the level inverse time angle of the scraper plate 7b of even level is 30
0.All charging tray 8a, 8b are horizontal hollow disk, be connected with shell 1 by support 11, its left and right sides is connected with escape pipe 4 with weary gas air inlet pipe 2 respectively, central openings establishes rotating shaft 3, rotating shaft 3 is not connected with charging tray 8a, 8b, reductor 13 is established in one end of rotating shaft 3, and circular boop 10 is established in position rotating shaft 3 is positioned at above charging tray 8a, 8b, and circular boop 10 level connection joint is with pivoted arm 9a, 9b of multiple scraper plate 7a, 7b.Cover top portion arranges gas collection mouth 6.Hollow charging tray 8a, 8b all connect weary gas air inlet pipe 2 and escape pipe 4.From the different of other even level, 18th layer is that its charging tray 8c is closely connected with shell 1, and set out material mouth 14 in its side.
Wet cotton protein material, after charging aperture 5 enters this drying tower, hollow charging tray 8a, 8b at different levels is successively dried.Horizontal up time angle 30 is had between scraper plate 7a above charging tray 8a and pivoted arm 9a
0, thus material to be gone forward one by one movement to central authorities under it scrapes clockwise effect, the blanking hole 12 in the middle of charging tray 8a drops.On the contrary, level inverse time angle 30 is had between the scraper plate 7b on charging tray 8b and pivoted arm 9b
0, thus movement of going forward one by one laterally under making material scrape effect in the clockwise direction, drop from charging tray 8b outer.Until the 18th layer, discharge from discharging opening 14.The charging tray 8c of the last one deck in bottom is closely connected with shell 1, and sets out material mouth 14 in its side.Steamed the de-mist containing organic solvent and methyl alcohol to be collected from gas collection mouth 6.
