Abstract
The utility model provides a left-right balance low shear flow horizontal reactor. The utility model includes a motor, a mixing shaft which is connected with the motor through a transmission mechanism and a horizontal mixing cylinder, wherein, an external spiral and an internal spiral which present the reverse rotation directions are arranged on the mixing shaft, the utility model is characterized in that: the mixing shaft, the external spiral and internal spiral which are arranged on the mixing shaft are all arranged on an eccentric circle of the mixing cylinder, and the axial cross-sectional areas of the external spiral and the internal spiral which are under the liquid level of the medium are equivalent.
Description
Technical field:
The utility model is relevant with the horizontal reacting still, and is relevant with the low shear flow horizontal reacting still of left and right sides balance especially.
Background technology:
Reactor can be described as the key equipment of any chemicals production, the evolution of the kind of all kinds of chemicals, quality and production capacity thereof, it also is the evolution of various reactor researchs, and various vertical response stills are normally used reactors, and the horizontal reacting still is a kind of special reactor.
The vertical response still is to set up needed field of flow by the distribution of axial flow, runoff, peripheral flow, and it needs certain rotating speed to keep, and distributes in any case, all produces very high shear flow between inside and outside laminar flow.
Development along with chemical industry, the particularly development of fine chemistry industry, make chemical reactor be able to deep research, and develop to the diversification special equipment, a lot of special chemical reaction technologies have not been that vertical response still gained can be finished, neither some easy paddles or helical-ribbon type horizontal reacting still can finish.Particularly for the substance reaction that requires low shear flow, its low shear flow field must guarantee that like this, vertical response still and easy horizontal reacting still are not set up required field of flow, just do not satisfy the requirement of low shear flow yet by reducing rotating speed; In addition, for the king-sized chemical reaction of ratio that some solid matters account for, the vertical response still can not set up required field of flow, thereby the reaction dead angle occurs.For this reason, often need to add a kind of liquid phase medium and improve the flow field to satisfy technological requirement, isolate this medium after the reaction again, cause having increased the twice technical process, its structure is that reaction process is long, the energy consumption height, and product quality is low.
The utility model content:
The purpose of this utility model is in order to overcome the deficiency of vertical response still and general simple and easy horizontal reacting still, to provide a kind of and can reach left and right sides balance, the long-pending eccentric low shear flow horizontal reacting still of left and right sides balance that stirs and realize low shear flow of full visitor.
The purpose of this utility model is achieved like this:
The utility model left and right sides balance shear flow horizontal reacting still comprises motor, the shaft that is connected with motor by transmission mechanism, horizontally-arranged mixing drum, the opposite external spiral of rotation direction, inside spin are arranged on the shaft, it is characterized in that shaft and on external spiral, inside spin all place on the off-centre operation of mixing drum, external spiral, the axial cross section of inside spin under the medium liquid level are long-pending to be equated.
The gyration track of above-mentioned external spiral and mixing drum inner chamber body shape are coincide.
Above-mentioned external spiral, inside spin are respectively slick and sly cross sectional shape.
Above-mentioned external spiral, inside spin are respectively left-hand screw, right-hand screw.
Referring to Fig. 1, Fig. 2, when shaft turned clockwise, external spiral on the fluid layer advanced reaction medium outside to the left side, and inside spin advances reaction medium to the right on interior fluid layer simultaneously.The axial cross section of inside spin under the medium liquid level amasss F
2Must equal the long-pending F of the axial cross section of external spiral under the medium liquid level
1Make reaction medium be in right balance in field of flow and flow, realize the stirring of left and right sides trimming moment, shaft places on the off-centre operation of mixing drum, outward, unequal section appears in the gap between inside spin and the mixing drum inwall, makes reaction medium constantly change flow velocity when circumferential flow.The track that external spiral is done gyration can be walked around the gross area of mixing drum.Even when low speed turns round, also can make reaction medium in field of flow, not have the dead angle.Outward, inside spin is slick and sly tangent plane shape, guarantees that further medium reaches the effect of low shear flow at the volley.
The utility model horizontal reacting still can overcome existing reactor weak point.This be because: 1, this horizontal reacting still utilizes a kind of balance agitator of special shape, can reach total volume left and right sides balance and stir, and makes rotating speed and field of flow irrelevant substantially, thereby can keep the field of flow of hanging down shear flow; 2, in the basic phase of solid material conduct, liquid phase substance is during as the reaction of decentralized photo, can finish the one-step method reaction, need not to add again any central fluid medium, add that the stirring in the reactor do not have the dead angle, thereby each phase material can fully be mixed, improved the process conditions of reaction, the yield and quality of chemicals is greatly improved.
In sum, the utility model horizontal reacting still, can make reaction medium reach the multinomial function that left and right sides balance stirs, the low speed total volume stirs, off-centre stirs, low shear flow stirs, the chemical reaction process conditions of some specific (special) requirements have been satisfied, realized under the slow-speed of revolution, low shear flow state, improve the possibility of agitated medium uniformity coefficient to greatest extent, thereby satisfied the requirement of some special chemical reactions.

Fig. 1 is the utility model structural representation.
Fig. 2 is shaft, the inside and outside spiral sectional position schematic diagram in mixing drum.
The specific embodiment mode:
Referring to figure i, Fig. 2, the utility model comprises motor 1, is subjected to the thong shaft 3 of transmission mechanism output belt pulley of motor-operated transmission mechanism 2, one ends, mixing drum 4, the external spiral 5 of left-hand screw shape, the inside spin 6 of right-hand screw shape.Shaft 3 all places on the off-centre operation of mixing drum 4 with outer, inside spin 5,6.External spiral is respectively slick and sly cross sectional shape.External spiral, inside spin are at the area of section F of the axial cross section of medium liquid level A, A
1, F
2Equate.The gyration track of external spiral and mixing drum inner chamber body shape are coincide.Sequence number 7 is a reaction medium among the figure.
