Description

Continuous Emulsifier

The utility model relates to a kind of new type of continuous emulsifier unit that the emulsion serialization is produced that is suitable for.

At present, in Emulsion Explosive Production, the emulsifier that continuous emulsification technology adopts mostly is colloid mill or other self-control emulsifier unit, but all exist following problem to some extent: (1) energy consumption height, production capacity is low, and as when production capacity is 1.0～2.0t/h, power of motor is generally 9～15kw; (2) Continuous Emulsifier adopts pre-mixing apparatus such as nozzle-type premixed device or static mixer etc. usually, carries out the essence breast in the emulsifier through just entering behind the thick breast; (3) volume is bigger, and easily Vent leaks, and has certain safety problem; (4) complex structure, not easy-maintaining.

The purpose of this utility model is: for CONTINUOUS PRODUCTION LINE OF EMULSION EXPLOSIVE provides a kind of production capacity big, volume is little, energy consumption is low, simple in structure, Continuous Emulsifier for ease of maintenaince.

For achieving the above object, the utility model has been taked following technical scheme:

1, according to characteristic Design such as the formation mechanism of the emulsion of comparing in the Emulsion Explosive Production height and hydrodynamics thereof based on turbine (14) and be aided with the composite stirring equipment of dispersion plate (13), flow-stopping sheet (15) and paddle (11).This device is positioned at the emulsion tank of actuating unit bottom, is made up of axle sleeve (3), shaft (12), top cover (5), feed pipe (10), paddle (11), turbine (14), dispersion plate (13), flow-stopping sheet (15) etc.The relation of its each several part is as follows:

Shaft (12) vertically passes top cover (5) and dispersion plate (13), and is fixed on the top cover (5) by axle sleeve (3), bearing, sealing device etc., links by shaft coupling (2) and motor (1) axle; Dispersion plate (13) links to each other with top cover (5) by feed pipe (10), and flow-stopping sheet (15) vertically is embedded on the periphery of dispersion plate (13); Paddle (11) and turbine (14) are contained in the top of shaft (12) respectively and do not hold, i.e. the above and below of dispersion plate (13).

In the not end of shaft (12), the below of dispersion plate (13) turbine (14) of 6～18 in impeller is installed, vertical with shaft (12), its impeller is sheet rectangle or square; Dispersion plate (13) is a circular sheet, its center has a circular port, the position that feed pipe (10) links to each other with dispersion plate (13) should be dropped within turbine (14) circumference, on dispersion plate (13) periphery, vertically be embedded with 10～40 flow-stopping sheets (15), these flow-stopping sheets (15) are sheet rectangle or square, are 10～90 ° of angles with peripheral tangent line.Like this, dispersion plate (13), feed pipe (10), flow-stopping sheet (15) form an organic whole with turbine (14), the profit phase materials constantly is ejected on the impeller of turbine (14) from feed pipe (10) mouth, after dispersion and shear action through turbine (14), being subjected to flow-stopping sheet (15) again further disperses and shear action, the material that emulsification is good moves to tank body top, and the material that emulsification is good is not back to the dispersion shear action that turbine (14) stands a new round from the centre bore of dispersion plate (13).

Paddle (11) is installed in the top of shaft (12), and the top of dispersion plate (13) has 1～6, and its blade and shaft (12) are 30～90 ° angle, and has shape hole, an ellipse garden at the blade middle part.Paddle can not only change the material movement direction, and the effect of shearing dispersion is also arranged, make emulsification is not good in the rising material material obtain the hole, ellipse garden of chance, especially the blade centre of emulsification again, the effect of shearing dispersion can also be strengthened, and paddle motion formed " cavity " can be eliminated.

2, emulsion tank is an interlayer container containing, is made up of interlayer (6), discharge nozzle (16), evacuated tube (8), water inlet pipe (9), return pipe (7) etc.Water inlet pipe (9) and return pipe (7) are communicated with interlayer (6), are used for logical circulating hot water or cold water to be incubated or to cool off; Discharge nozzle (16) is communicated with container on tank body top by interlayer (6), the emulsion matrix in the emulsion tank can be emitted; Evacuated tube (8) is passed interlayer (6) in tank base and is communicated with container, is used for discharging waste material or surplus water in the emulsion tank.Emulsification like this, discharging, cleaning are all very convenient.

3, this new type of continuous emulsifier partly is made up of actuating unit, agitating device, emulsion tank etc.Actuating unit is positioned at the top of emulsifier, is made up of motor (1), electric machine support (4) and shaft coupling, and motor (1) links to each other with agitating device by shaft coupling (2) with electric machine support (4) supporting.Agitating device is positioned at the emulsion tank of actuating unit bottom, like this each several part of emulsifier is organically combined, and has not only simplified mechanism, has reduced cost, and for ease of maintenaince.This Continuous Emulsifier, its material can directly enter wherein and can emulsification go out high-quality gel without premix or thick breast.

Accompanying drawing is a basic structure schematic diagram of the present utility model.

The drawing symbol is respectively: 1-motor, 2-shaft coupling, 3-axle sleeve, 4-electric machine support, 5-top cover, 6-interlayer, 7-return pipe, 8-evacuated tube, 9-water inlet pipe, 10-feed pipe, 11-paddle, 12-shaft, 13-dispersion plate, 14-turbine, 15-flow-stopping sheet, 16-discharge nozzle

Use step of the present utility model is:

1, calculate oil, water flow, the production capacity of setting emulsifier is 2 tons/hour, calculates oil phase and the water flow is respectively 160 liters/hour and 1330 liters/hour by the composition of explosive formulation;

2, prepare oil phase and water on request, and its temperature is controlled at respectively in the scope of 90～100 ℃ and 105～115 ℃, standby;

3, open hot water cyclesystem to emulsifier extremely the pumping line system carry out preheating, and make that temperature is not less than 80 ℃ in its conveyance conduit and the emulsifier tank body;

4, start emulsifier, open oil phase pump, water pump then in order, and will carry out emulsification in oil phase, the water adding emulsifier by aforementioned traffic requirement;

5, promptly have the good gel of emulsification to discharge from the emulsifier discharging opening uniformly in the several seconds, so far emulsifier enters the ordinary production state;

6, produce when finishing, clean relevant pipeline and equipment etc. by technological requirement.

The utility model production and application is the result show, its continuous emulsification is respond well. It is main Advantage has:

1, this Continuous Emulsifier is vertical, and production capacity is big, and energy consumption is low, as production capacity be 2 tons/little The time, its energy consumption only is about 1/10th of general colloid mill and other type Continuous Emulsifier;
