Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of device that can complete solid material simultaneously and fully stir and have effective adhesive.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of screw rod stirring mixer, comprises mixer container, drive unit, agitating screw; Wherein, agitating screw is lying in mixer container inside, and is connected with drive unit; In the technical scheme adopting at the utility model, the quantity of agitating screw is two (can think that agitating screw occurs in pairs): two screw rods are connected with two drive units respectively, and can under the drive of each automatic drive device, rotate respectively, the pitch of two screw rods meets the situation that increases progressively in gradient or successively decrease simultaneously.The pitch of the two agitating screws situation that increases progressively in gradient or successively decrease respectively, can realize the pressure contact to raw material and roll, and guarantees fully contacting and extruding between solid material and binding agent, thereby reaches the object that has effective adhesive.Two pitch distributions that agitating screw does not wait, mean that different bond effects can and deposit from different mixing effects, it is advantageous that and can carry out stirring and the bonding of laddering/degression type again and again to solid material and binding agent, thereby reach best mixing effect and bond effect.
Preferably, the direction of rotation of described two agitating screws is contrary.For example, drive unit drives a wherein agitating screw to clockwise rotate, drive the solid material of a side in mixer container and binding agent to intermediary movements, and another root screw rod rotates counterclockwise, drive the solid material of opposite side in mixer container and binding agent to intermediary movements; All materials, all from two side direction intermediary movementses, are realized Forced Mixing and the extruding of material between two screw rods, reach even mixing and have the object of effective adhesive.Otherwise two screw rods drive solid material and binding agent from centre to two lateral movements simultaneously, realize the pressure extruding of material between two spirals and each self-corresponding mixer container both sides inwall.By repeatedly replacing of said process, finally complete solid material and mix and bonding with the efficient of binding agent.
Preferably, the rotating speed of described two agitating screws is not identical.Two agitating screws of different rotating speeds complete binding agent and solid material are forced to contact to greatest extent in the time that screw thread is nearest each other, and now, it is best that bond effect reaches; Immediately along with mutual distance from the close-by examples to those far off, will Automatic-falling with the well-bonded solid material of binding agent, participate in next round even more the pressure of next round roll process; Go round and begin again, thereby complete the effective adhesive that has of raw material.In addition, the different agitating screw of rotating speed has certain shearing force to the thing piece of molding bonded, thing piece is had to certain role of tear, therefore, just be easy to constantly be torn for the not good thing piece of some bond effect, it is diminished, force its again participate in next round even more the pressure of next round roll bonding process, thereby guarantee bonding effect.
Preferably, described drive unit comprises stepless speed-change motor, like this can be more easily according to the required rotating speed that regulates agitating screw of actual conditions.
The beneficial effects of the utility model are, a kind of device that can complete raw material simultaneously and fully stir and have effective adhesive is provided, and have the advantages such as simple in structure, easy to operate; The regulation and control of mixing speed continuous stepless, can carry out selection speed according to actual conditions, make stirring efficiency obtain larger raising; Use a pair of pitch to increase progressively in gradient respectively and the successively decrease agitating screw of situation of gradient rotates under the drive of drive unit, realize the pressure of solid material and binding agent is contacted and rolls and bond; Select different rotary direction and rotating speed, realize multi-form extruding, shear texts, ensure the well-beaten effect that has effective adhesive that simultaneously reaches.
