The pitch heating kettle comprises a stirring kettle, and is characterized by further comprising a stirring device, a heating device and a controller; brackets are arranged at the bottom of the stirring kettle; a temperature sensor is arranged in the stirring kettle; the stirring device comprises a motor and a stirring shaft; the motor is in transmission connection with the stirring shaft; the stirring shaft penetrates into the stirring kettle; blades are arranged on the stirring shaft; the heating device is fixedly connected with the stirring kettle; the controller is in electric connection with the motor; the controller is fixedly connected with the stirring kettle through a connecting rack; the temperature sensor is in electric connection with the controller. The pitch heating kettle has the benefits that miniaturization of the pitch heating kettle is realized, the process of heating pitch can also be mechanized even in a construction site, the manual participation degree is reduced, uniform heating of the pitch is ensured, the body health of both workers and peripheral personnel can be protected, and the peripheral environment is safeguarded.
Description
Technical field
The utility model relates to field of civil engineering, relates in particular to a kind of asphalt heating pot.
Background technology
Bituminous concrete, English name: bituminous concrete, be commonly called as asphalt concrete, through artificial selection, to there is the mineral aggregate (rubble or grating gravel, aggregate chips or sand, breeze etc.) and a certain proportion of bitumen for road use material of certain gradation composition, the compound that mixing forms under strict controlled condition.
The intensity of bituminous mixture is mainly manifested in two aspects.The one, the adhesion stress of the cementitious matter that pitch and breeze form; Another is inner frictional resistance and lock knot power between aggregate particle.The huge surface area of breeze fine grained (being mostly less than 0.075 millimeter) makes bituminous material form film, thereby has improved adhesion strength and the temperature stability of bituminous material; Lock knot power mainly produces between coarse aggregate particle.While selecting bituminous concrete mineral aggregate gradation, to take into account both, with reach add after appropriate pitch compound can form closely knit, stable, roughness is suitable, long-lived road surface.Coordinate mineral aggregate to have several different methods, can calculate with formula, also specified grading scope by rule of thumb, China adopts the grading limit of experience curve at present.Pitch Optimum in bituminous mixture, should determine with the practical situation in laboratory test result and building site, generally in relevant specification, all shows the guidance that the asphalt content scope that provides a reference is joined as examination.When mineral aggregate kind, grading limit, bitumen consistency and kind, mix and stir facility, local climate and traffic characteristic fixedly time, also can adopt empirical formula estimation.
The bituminous mixture that heat is mixed should be used in concentration point mechanical mixing.Generally select fixed Re Ban factory, at the long appropriate to the occasion mobile hot of selecting of circuit, mix machine.The bituminous mixture of cold mixing can central mix, also road mix on the spot.The capital equipment of pitch batching plant comprises: asphalt heating pot, sandstone storage at, mineral powder bin, heated roller, lorry mounted mixer and weighing equipment, steam heating boiler, bitumenpump and pipeline, dust removal installation etc., sub-sieve again and bunkerage (seeing that bituminous mixture mixes and stirs base) that some also has heat to gather materials.Lorry mounted mixer can be divided into again continous way and the large class of batch-type two.In preparation technology, the past, adopt first dried sand material after heating more, then mixed and stirred with heated bitumen and cold breeze.Recently, develop again and a kind ofly first with heated bitumen, mix wet gathering materials, and then the heating method of mixing thoroughly, to eliminate because of the flying dust when heating and the oven dry that gathers materials.While adopting rear a kind of technique, the moisture effects bituminous concrete application life in compound be prevented from remaining in, preferably asphalt anti-stripping agent can be adopted, to strengthen water resistant ability simultaneously.
Asphalt heating pot of the prior art maximizes, mechanization degree is much higher is present in industrial building, mobile inconvenience, and workman usually takes to boil with iron sheet barrel the mode of artificial stirring in actual road construction.Such preparation method not only makes pitch not stir to be heated, and the irritative gas exhaling in the process of heating contaminated environment not only, also can damage greatly the healthy of operating personnel and periphery personnel.
Utility model content
Problem to be solved in the utility model is to provide a kind of asphalt heating pot mobile, miniaturization of being convenient to.
The technical solution of the utility model is as follows: a kind of asphalt heating pot, comprise agitated kettle, and it is characterized in that: also comprise mixing plant, heater and controller;
Described agitated kettle bottom is provided with support; In described agitated kettle, be provided with temperature pick up;
Described mixing plant comprises motor, shaft, and described motor and shaft are in transmission connection, and described shaft gos deep in agitated kettle, and described shaft is provided with blade;
