Abstract

The utility model relates to an experimental device of the road material, especially to an experimental heating and agitating device for pitch mixture. The invention has solved the problem that the present experimental equipment can only agitate and the preheating of the gravel needs separate drying oven. The utility model is provided with an agitating arm and a tank installed on the base frame. The exterior of the tank is provided with the heating wire and insulating layer for heating, the upper part of the tank is provided with a metal cage-type casing which can be lifted upward. A waveguide mouth is provided inside the casing and the waveguide mouth is provided with the magnetron connected with the voltage transformer. A load bearing plate is arranged at the lower part of the casing and the load bearing plate is pressed on the foot step inside the tank when it is working. The device can heat the gravel with microwave while heating and agitating pitch mixture, and the drying oven is not needed. So, the invention can be widely used in the experiment of the road material.

Description

A kind of experiment bituminous mixture heating and stirring device

Affiliated technical field

The utility model relates to a kind of experimental facilities of pavement material, particularly a kind of experiment bituminous mixture heating and stirring device.

Background technology

The bituminous mixture heating stirrer of current experiment usefulness is just stirred stone and pitch under the heat tracing state, preheating then will be carried out separately with baking oven before the stirring of stone.So not only will acquire baking oven, and the electric energy that baking oven expends is more, the time that needs is longer, and want tens hours the preheating time of stone, causes man power and material's waste.

Summary of the invention

The purpose of this utility model provides a kind of energy-efficient, when heating mixes material, can also heat the experiment bituminous mixture heating and stirring device of solid materials such as stone.

The technical solution of the utility model is; A kind of experiment bituminous mixture heating and stirring device, it has mixing arm and the tank body that is installed on the base, heating wire and the insulation layer that is used to heat is housed in the outside of tank body, a hood-shaped housing of the metal that can upwards mention is arranged on the top of tank body, the waveguide mouth is housed in housing, the magnetron that links to each other with transformer is housed on the waveguide mouth, in the lower end of housing load-bearing plate is housed, load-bearing plate just rides on the step surface of tank interior or the housing lower surface rides on the tank body upper surface during work.

The rotating shaft of the mixing arm of this device is loaded in the endoporus at housing and load-bearing plate middle part, the rotating shaft upper end is connected with motor shaft with shaft joint, motor is fastened on the riser lower surface, riser tightens together with double-screw bolt and housing, the riser upper surface is welded with enhancing ring, so that with lifting appliance or equipment riser and housing, mixing arm etc. are raised up simultaneously.

Be contained in the shape of the waveguide mouth in the housing, can be tubular, basin shape or taper, comprise taper shape and pyramid, also can be their combined shaped, the waveguide mouth is made by metal material.

For the ease of the compound that stirs is poured out, in the both sides of tank body bottom a back shaft is arranged respectively, back shaft is contained in the bearing support that is fastened on the base.

In order to improve the thermal efficiency, the silicon nitride plate is housed on the upper surface of load-bearing plate.

In the tank body of the utility model bottom, can the compound of stone and pitch be stirred under heated condition, and at the same time, we can be placed on stone on the load-bearing plate, the microwave that utilizes the energising back to produce heats it, has so just simplified equipment, has saved baking oven.We know in addition, microwave when propagating, run into metallic conductor can not penetrate by, be not absorbed yet, but all reflect back.Therefore heating using microwave does not have heat radiation, has heating rapidly, the characteristics that thermal loss is few.In this device, install the silicon nitride plate on the load-bearing plate again additional, can further improve the thermal efficiency.The experiment proved that meeting the requirements of temperature with this device heating stone only needs one hour, raises the efficiency tens times than baking oven.So the utility model also has energy-efficient characteristics.The utility model can be widely used in the experiment of pavement material.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.

Figure one is a structural representation of the present utility model.
