Background technology
Rape is the main oil crops of China, and output ranks first in the world.The product of current rape secondary industry has only rapeseed oil and grouts, and grouts contain poisonous or anti-nutrient substances such as a large amount of sulphur glucoside glucosides, polyphenol, phytic acid, cause it to add in the general mixed feed and go, and can not be applied in the breed of high-end fish with 3% ratio.
Because the material properties of dregs of rapeseed cake itself is extremely special, existing water-soluble albumen also has glucide, makes shortcomings such as the equipment in dregs of rapeseed cake deep processing detoxification reaction stage exists more than filtration time length, poor filtration effect, the material loss.
Summary of the invention
Technical problem to be solved by this invention is: a kind of agitation filtering pot for rapessed cake dreg de-toxin reaction is provided, it can realize that the deep processing of rape grouts produces the technology of protein concentrate, and obtain the nutritive value rapeseed protein concentrate suitable with fish meal, add mixed feed to bigger ratio, be applied in the breed of high-end fish.
The present invention solves the technical scheme that its technical problem adopts: be provided with motor, screen cloth, and by motor-driven and be positioned at the rabbling mechanism of upper tank body; Screen cloth is contained on the bottom in the upper tank body by gripper shoe; Upper tank body is cylindrical, and it is conical that lower tank is, and the two is combined as a whole, and a water inlet is respectively arranged, and lower tank also is provided with discharging opening and leakage fluid dram.
The present invention compares with existing equipment, its main advantage is: integrate reaction, stirring, filter three kinds of functions, problem such as solved more than filtration time length that existing equipment exists, poor filtration effect, the material loss, finish the dregs of rapeseed cake deep processing well and produce the core process of protein concentrate, with multiple poisonous or anti-nutrient substance removal such as the sulphur glucoside glucoside in the rape grouts, polyphenol, phytic acid, obtain the suitable rapeseed protein concentrate of nutritive value and fish meal, thereby add mixed feed to bigger ratio, be applied in the breed of high-end fish.
The specific embodiment
The invention provides a kind of agitation filtering pot for rapessed cake dreg de-toxin reaction.
The invention will be further described below in conjunction with embodiment.
Agitation filtering pot for rapessed cake dreg de-toxin reaction provided by the invention, its structure be as depicted in figs. 1 and 2: be provided with motor 1, screen cloth 16, and by motor 1 drive and rabbling mechanism that be positioned at upper tank body.This filtering tank is made up of the last lower tank that is combined as a whole.Upper tank body is cylindrical, and its top is provided with water inlet 5.It is conical that lower tank is, and its sidepiece is provided with discharging opening 14 and following water inlet 10, and leakage fluid dram 11 is arranged at the bottom.Screen cloth 16 is contained on the bottom in the upper tank body by gripper shoe 15, and gripper shoe 15 can support by the 8-10 root cramp bar of evenly arranging 13, and the upper and lower side of these cramp bars is weldingly connected with gripper shoe 15 back sides, lower tank inwall respectively.
Described rabbling mechanism is made up of shaft 2 and the double-deck axial-flow type paddle that is mutually the right angle, and shaft can link to each other with the arbor of motor 1 by shaft coupling or alternate manner.Described double-deck axial-flow type paddle, the length of its upper strata paddle 18 is less than the length of lower floor's paddle 17; The inwall gap of the length of lower floor's paddle and upper tank body is 6-10cm.
Described motor 1 can be contained on the support plate 4 by support 3.Support plate 4 is across on the uncovered edge of upper tank body, and fixedly connected with bolt or welding manner.Support 3 is the cup of back-off, fixedlys connected with bolt or welding manner with support plate 4 in the edge of its underpart.
Described screen cloth 16 can adopt 30-50 order stainless steel mesh, or decides according to actual needs.
Sidepiece at last lower tank respectively has four recoil mouths, and the recoil mouth 7 of upper tank body is between upper strata paddle 18 and lower floor's paddle 17, and the recoil mouth 8 of lower tank is positioned at the below of screen cloth 16.
Described upper tank body, its sidepiece are provided with the equally distributed 4-6 that an is attached thereto feet 6, and this feet is fixedly connected on the workbench by bolt or welding manner.On the taper seat of lower tank, be provided with two circle stiffening rings 9.
Above-mentioned upper and lower tank body can be made by corrosion-resistant material, makes as stainless steel OCr18Ni9 (claiming stainless steel 304 again).
Agitation filtering pot for rapessed cake dreg de-toxin reaction of the present invention, its course of work is: dregs of rapeseed cake drops into from the top of detoxification reaction agitation and filtration jar, add a certain proportion of water by last water inlet 5, opening motor 1 driving rabbling mechanism stirs, dropping into auxiliary material again stirs, make that material fully reacts, after the detoxification, open the leakage fluid dram 11 of filtering tank bottom, drain after then containing the filtration of reaction water by screen cloth 16 of poisonous or anti-nutrient substance such as sulphur glucoside glucoside, polyphenol, phytic acid.Subsequently, add clear water from last water inlet 5 again, stir once more, open discharging opening 14, together extract the solidliquid mixture of dregs of rapeseed cake after handling and water formation out filtering tank.
When starter motor 1 begins to stir, need the mouth of unlatching recoil earlier 7 to inject water under high pressure reactant is turned over, reduce the resistance of start.Open recoil mouth 8, can be used to clean screen cloth 16, prevent to stop up.Following water inlet 10 is used for preventing the obstruction of leakage fluid dram 11.
