Description

A kind of equipment of producing modified asphalt

Technical field

The utility model belongs to modified pitch production technical field, more particularly to a kind of equipment for producing modified pitch.

Background technology

Widely, the building stones available for asphalt blending station are mixed and stirred for the application of modified pitch, it can also be used to new face of repairing the roads Tack coat and sealing, if in construction period, daily demand amout is up to hundreds of tons；For producer as marketing modified pitch, day The demand of sales volume will reach nearly kiloton.The production technology of modified pitch is, about 180 DEG C of 70# or 90# heated bitumens, with SBS modifier Mixed in production tank, by the high speed shear of colloid mill, after being developed 2-3 hours in development tank, as finished product.Reach company Continuous formula production, it is necessary to which the condition possessed is how to ensure the continuous 70# or 90# hard pitches for providing about 180 DEG C.Current pitch storehouse The storage of matrix pitch, typically according to the number of daily output/sales volume, matrix pitch tank volume is in 500-1000 side, if handle So many pitch is all heated to 180 DEG C from 120 DEG C or so of storage temperature, it may be desirable to many heats, wastes many energy. How in high volume, economic, energy-conservation, efficiently continuous production modified pitch, rational production technology are most important.Therefore, to keep away Exempt from above-mentioned technical problem, it is necessory to provide a kind of new continuous modified asphalt production equipment, to overcome in the prior art The defect.A kind of continous way modification drip is devised for the Chinese utility model patent of this Patent No. 201320227093.2 Blue or green production equipment；The equipment include matrix pitch pump, heat exchanger, SBS modifier auger conveyor, production tank, feeding pump and Colloid mill；Wherein, the matrix pitch pump, heat exchanger are sequentially connected to produce tank；The SBS modifier auger conveyor also connects It is connected to production tank；The production tank is provided with a circulation pipe, and the feeding pump, colloid mill are set in turn on circulation pipe.This sets It is standby to make pitch that temperature be risen into 180 DEG C in the moment by heat exchanger, so save by needed for a large amount of asphalt heatings when Between, improve production efficiency；Environmental protection and energy saving simultaneously, reduce the energy and cost needed for asphalt heating, and avoid pitch in length In the heating condition of high temperature in time, aging is formed or rotten.The equipment by matrix pitch due to being warming up to 180 degree, therefore, In the easy expanded by heating deformation of the feed pipe that is connected with heat exchanger exit end, with the presence of causing the potential safety hazard of booster；And in base Scattering and disappearing with heat after matter pitch outflow pipeline, matrix pitch temperature will be reduced, so as to influence to prepare effect.

Utility model content

The purpose of this utility model is solution above-mentioned technical problem, and there is provided a kind of equipment of producing modified asphalt, the equipment The pipeline that heat exchanger exit end can be made connected possesses certain dilatancy in transport high temperature matrix pitch, is not in that booster shows As safe and reliable.

The technical solution of the utility model is as follows：

A kind of equipment of producing modified asphalt, including matrix pitch pump, heat exchanger, production tank；Wherein, the matrix pitch Pump, heat exchanger are sequentially connected to produce tank.

Connected between the feed pipe and the production tank of the connection of heat exchanger exit end by a pair of flanges of arrangement up and down, two A sliding equipment is respectively equipped with the pipeline that flange is each connected, two sliding equipments are arranged symmetrically above and below；It is above Sliding equipment include the core pipe inside the insertion feed pipe port of export, the core pipe is that one section of outer wall connects with charging inside pipe wall slip Tactile pipe, the bottom of core pipe is integrally provided with circular otic placode, and the feed pipe port of export is close in the upper surface of the otic placode End face of flange；In the upper end of the core pipe provided with the circular tube shaped bushing in insertion core pipe, the top of the bushing is integrally Provided with circular flange, the periphery of the flange is with feeding inside pipe wall close proximity and being fixed as one, in core pipe tube wall Upper surface and flange lower surface between provided with being enclosed on cylindrical spring on bushing, the two ends of the cylindrical spring respectively with core Tube wall upper surface and flange lower surface are fixedly linked.

Some springs are provided between the otic placode and flange of the sliding equipment of lower section, the spring bottom end is inserted and secured on this In blind hole on end face of flange；The pillar of some obstruction matrix pitch flowings is up further fixed on the core pipe inwall of lower section.

Further, four pillars tilted down are equipped with the inwall of the core pipe above and below, this four pillars Uniform intervals are arranged.

Further, the connecting bolt of flange runs through upper and lower two pieces of otic placodes, and bolt penetration hole on otic placode with it is described Optical axis section smooth contact on connecting bolt.

The beneficial effects of the utility model：The utility model passes through the pipeline exported in heat exchanger and production tank joint Set sliding equipment to realize the expansion elongation of this section of heated pipeline, it is to avoid split pipe.Operationally, high temperature matrix pitch flow through into Expects pipe, feed pipe is heated, feed pipe expansion axial elongation, the bullet set between the otic placode and flange of compression lower section sliding equipment Spring, realizes and axially wriggles, further, since washing away for matrix pitch, is aided with the inhibition of pillar, two core pipes are same up and down When downward compression spring, now, will not be separated between the otic placode and flange between two core pipes, thus also will not seepage, realize Dynamic sealing.When matrix pitch no longer flows, cylindrical spring respectively resets each connected core pipe, realizes operationally automatic Expansion elongate gaps amount is reserved for pipeline.
