Problems solved by technology

[0003] The preparation of existing asphalt concrete mostly uses a mixer to mix sand and mortar with liquid asphalt, but the existing mixing equipment mainly has the following problems in the process of preparing asphalt concrete: a: The liquid asphalt is mixed and injected into the concrete for mixing. Due to the viscosity of asphalt and gradually hardens as the temperature of liquid asphalt decreases; resulting in uneven mixing of asphalt and concrete; b: When the stirring rod mixes the internal asphalt concrete, the internal agitator is easy to adhere to the stirring rod and affect the stirring rod Stir the internal mixture, and the existing stirring rods mostly move in the circumferential direction to stir the internal mixture. The circumferential movement is not evenly stirred, and the internal mixture cannot be completely stirred to achieve full stirring.

Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific drawings. It should be noted that, in the case of no conflict, the embodiments and Features in the embodiments can be combined with each other.

[0028] Such as Figure 1 to Figure 4 Shown, a kind of asphalt concrete preparation process, concrete asphalt concrete preparation process is as follows:

[0029] S1. Injection of mortar and gravel: mix the mortar and gravel to be stirred into the interior of the container module 24 according to a certain ratio;

[0030] S2. Concrete mixing: the mortar and gravel inside the container module 24 are driven by the drive motor 21 to rotate and cooperate with the mixing unit 4 to fully mix the mortar and gravel into concrete;

[0031] S3. Liquid asphalt injection: inject a certain volume of liquid asphalt into the interio...

Abstract

The invention provides an asphalt concrete preparation technology. A lower support, a drive unit, an upper support and a stirring unit are cooperated to complete the preparation of an asphalt concrete. The asphalt concrete preparation technology provided by the invention can solve the problems mainly existed in the process of preparing the asphalt concrete through existing stirring equipment: a, when liquid-state asphalt is mixed and injected into the concrete so as to be stirred, the asphalt and the concrete are mixed non-uniformly due to the restriction of the viscosity of the asphalt and the gradual hardening along with the temperature reduction of the liquid-state asphalt; and b, when the inner asphalt concrete is mixed and stirred through a stirring rod, the inner mixture is easy to adhere onto the stirring rod so as to affect the stirring carried out on the inner mixture by the stirring rod, the existing stirring rod is used for stirring the inner mixture through circumferentialmovement, the nonuniformity is caused by the stirring through circumferential movement, the sufficiency in stirring cannot be realized since the inner mixture cannot be thoroughly turned over, and thelike.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to an asphalt concrete preparation process. Background technique [0002] Asphalt concrete, commonly known as asphalt concrete, is artificially selected with a certain grade of mineral materials (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials, and mixed under strictly controlled conditions. prepared mixture. [0003] The preparation of existing asphalt concrete mostly uses a mixer to mix sand and mortar with liquid asphalt, but the existing mixing equipment mainly has the following problems in the process of preparing asphalt concrete: a: The liquid asphalt is mixed and injected into the concrete for mixing. Due to the viscosity of asphalt and gradually hardens as the temperature of liquid asphalt decreases; resulting in uneven mixing of asphalt and concrete; b: When the stirring rod mixes t...
