Description

The overflow blender

The utility model belongs to a kind of mechanical type processing mixing apparatus, specifically a kind of meticulous fragmentation, processing that is used for pitch and aqueous emulsion, mixes and the special equipment of emulsification, is used among the industrial continuous production of meticulous emulsified asphalt product.

The asphalt emulsification technology is the new technique of progressively using both at home and abroad energy-saving and cost-reducing, environmental protection that has, and mainly is to be formed through emulsification by pitch and water.At present because this technical know-how and practice exist certain difference, make the corresponding hysteresis of production technology means, emulsifying effectiveness and stability are poor, can not effectively store, transport and use, even the external complete production unit with the higher cost import also can't be realized serialization production, so the asphalt emulsification technology is paced up and down on discontinuous batch process and direct applied level always.

The purpose of this utility model is exactly in order to address the above problem, and a kind of overflow blender is provided, and is used for the industrial continuous production technology of emulsified asphalt product, is a key corollary equipment.

The overflow blender is characterized in that being made up of vertical cylindrical shell, axis body, two groups of spouts and overflow-type output device; Axis body is the rigidity solid member, is separately installed with upper and lower cutterhead in the upper and lower of axis body, and several layers of square knife bar are installed at the middle part of axis body, the assembling that interlaces of each layer knife bar; Axis body is installed in the vertical cylindrical shell, and two groups of spouts and overflow-type output device are installed in the upper and lower of vertical cylindrical shell respectively.

The overflow-type output device is made up of overflow inlet, overflow outlet and pipeline, and the overflow inlet inserts from the bottom of vertical cylindrical shell, is connected to above connecting output with the overflow outlet behind the certain level height of upper tool pan by pipeline again.

The 90 ° of angles assembling that interlaces of each layer knife bar.

When the driven by motor axis body at the uniform velocity rotates, the upper strata cutterhead can make through the pitch of spout pumping input and aqueous emulsion and enter rotation, diffusion and blending mutually, and not producing liquid level seethes, bar shaped blade on the cutterhead carries out level and vertical cutting and fragmentation to the first mixing material in upper strata continuously simultaneously, and move under the balanced Luo rotation direction of control liquid level, cutterhead does not produce bonding with high viscosity liquid; Several layers of middle knife bar continue to implement mechanism broken, that disperse, stir and mix to mixing material; Lower floor's cutterhead also can be controlled emulsion simultaneously and can sedimentation not take place at the bottom of tube and help liquid guide flow except to the further meticulous pulverizing of emulsifying liquid.

The low level design of overflow inlet can make by mixed liquid and obtain big relatively incorporation time and effect in the from top to down motion process in less space, and the high-order design of the level of overflow outlet can keep and control the actual liquid level height in the cylindrical shell, when the liquid level level height does not reach the overflow outlet, mixing material can not flow out, and when the liquid in the continuous input overflow blender reaches the level height of overflow outlet, because gravitational pressure and liquid level difference that liquid constantly produces, can flow out the overflow blender after making liquid enter overflow situation.

The utility model is used for the industrial continuous production technology of meticulous emulsified asphalt product, can make the serialization processing under the synthetic realization equilibrium state condition of emulsified asphalt, and hot bituminous liquids of high viscosity and aqueous emulsion to input are respectively carried out the continous way fragmentation, stir, mix and emulsification, under the double action condition of the efficient dispersion force that at the uniform velocity powerful mechanical force and emulsifier special produce, rapidly with the main matter in the bituminous liquids--the bulk structure of the big molecule long-chain cohesion of gum asphalt is crushed to particulate very tiny and that particle size is average, and evenly dispersion suspension forms the emulsified asphalt product of the mutual balance and stability of oil-in-water state among aqueous emulsion.

The utility model has solved the synthetic of emulsified asphalt can not carry out the contradiction that serialization is produced, and make the pitch particulate more tiny evenly and be well-dispersed among the aqueous emulsion, thereby corresponding stability and the application characteristic that has improved emulsified asphalt realized the commercialization production and the application of emulsified asphalt.

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with schematic view illustrating.

As shown in the figure:

The 1st, vertical cylindrical shell, the 2nd, axis body, the 3rd, upper strata cutterhead, the 4th, knife bar, the 5th, lower floor's cutterhead, the 6th, spout, the 7th, overflow inlet, the 8th, pipeline, the 9th, overflow outlet.

The overflow blender is characterized in that being made up of vertical cylindrical shell, axis body, two groups of spouts and overflow-type output device; Axis body is the rigidity solid member, is separately installed with upper and lower cutterhead in the upper and lower of axis body, and several layers of square knife bar are installed at the middle part of axis body, the assembling that interlaces of each layer knife bar; Axis body is installed in the vertical cylindrical shell, and two groups of spouts and overflow-type output device are installed in the upper and lower of vertical cylindrical shell respectively.

The overflow-type output device is made up of overflow inlet, overflow outlet and pipeline, and the overflow inlet inserts from the bottom of vertical cylindrical shell, is connected to above connecting output with the overflow outlet behind the certain level height of upper tool pan by pipeline again.

The 90 ° of angles assembling that interlaces of each layer knife bar.

Two groups of spouts are sent into pitch and aqueous emulsion respectively, and each connects with delivery pump and flow control system.

The utility model adopts the enterprising gerotor type nature overflow layout that goes out to return again down to high position outlet, in the actual production of emulsified asphalt product, by aqueous emulsion spout 75 ℃ of aqueous emulsion to half volumes of pumping in cylindrical shell, closes infusion pump earlier; After startup overflow blender makes axis body rotate at the uniform velocity, again by pitch spout pumping hot asphalt liquid more than 120 ℃ in cylindrical shell, after the level height that the liquid level of fluid to be mixed reaches overfall enters overflow situation, restart the infusion pump synchronous transport, and the flow of rapidly adjusting bituminous liquids and aqueous emulsion respectively by the flowmeter flow makes it reach the processing compound index.Meanwhile, upper strata cutterhead, mediant layer knife bar and the lower floor's cutterhead of installing in the axis body assembly in the overflow blender is by the double action ability of the efficient decentralized educational level of mechanical force of at the uniform velocity rotating the difference in functionality that produces and the generation of the emulsifying agent in the aqueous emulsion, rapidly with the main matter in the bituminous liquids--the bulk structure of the big molecule long-chain cohesion of gum asphalt is crushed to particle very tiny and that particle size is average, and be evenly dispersed and be suspended among the aqueous emulsion, form the asphalt emulsion of oil-in-water basic status.Synthetic and the emulsification of asphalt emulsion is progressively finished from top to bottom, is depressed into the overflow flow export through outlet down and discharges naturally and enter the low level storage tank.Asphalt emulsion cooling naturally in the input holding vessel after even matter blender retrofit homogenize more promptly becomes emulsified asphalt product.This technical products can effectively storage, pumping, transportation and application under normal temperature condition.
