Background

In the construction of highways and roads, a large amount of road asphalt mixture needs to be used. In the prior art, when preparing an asphalt mixture, because a modifier and asphalt can be mixed and compatible at a certain high temperature, the asphalt and the modifier are generally injected into a stirring tank body after the temperature of the asphalt is raised, so that the asphalt and the modifier are quickly and uniformly mixed and compatible. Because the asphalt is in a molten state and has certain viscosity in the stirring process, the asphalt and the modifier cannot be uniformly mixed by using a common stirring device, and the asphalt and the modifier cannot fully generate physical or chemical reaction to influence the quality of a finished product.

In the prior art, chinese patent CN201721709372.7 discloses a road asphalt mixture stirring device, which comprises a stirring tank and a motor, wherein a modifier feeding port is arranged at the upper right side of the stirring tank, the modifier feeding port is embedded in the stirring tank, the motor is arranged above the stirring tank, the motor is fixedly connected with the stirring tank, a stirring shaft is arranged below the motor, and stirring blades are arranged below the stirring shaft.

Chinese patent CN201720863361.8 discloses a heat preservation type pitch agitated vessel finished product feed bin, including supporting leg, backup pad, heating fluid, radiator, mixing shaft and mixing thick liquid, the lower extreme of backup pad is provided with the supporting leg, and the upper end of backup pad is provided with the churn, the upper end of churn is provided with the raw materials entry, and the one end of churn is provided with first agitator motor, and the other end is connected with inhales the material pipe.

In these prior arts, the stirring efficiency is improved by changing the structure of the stirring blade. However, because the density of the asphalt is high, when the asphalt is mixed with powder or liquid materials, the powder and the liquid materials which need to be mixed stay on the surface of the asphalt for a long time only by stirring in the horizontal direction, and the mixing efficiency is poor.

SUMMERY OF THE UTILITY MODEL

The invention of the utility model aims to: to the problem that above-mentioned exists, provide a mixing arrangement for pitch production, can be through the stirring of vertical direction, with powder or liquid material and pitch intensive mixing, improve pitch mixing efficiency.

The utility model adopts the technical scheme as follows:

the utility model provides a mixing arrangement is used in pitch production, is in including a jar body the top and the bottom of jar body set up respectively with a jar pitch feed inlet, powder feed inlet and discharge gate of body intercommunication, at the internal agitating unit that is provided with of jar, a serial communication port, agitating unit includes at least one stirring structure, stirring structure includes (mixing) shaft and a plurality of stirring leaf, the stirring leaf evenly sets up on the week looks plane of (mixing) shaft, the (mixing) shaft is connected with the motor, the (mixing) shaft level sets up.

Due to the adoption of the structure, the stirring shaft is horizontally arranged, so that the stirring blade moves clockwise or anticlockwise in the vertical direction, the stirring blade can be added into the tank body, powder or liquid on the surface of asphalt is stirred to the lower part of the tank body, and the asphalt in the tank body is quickly and uniformly mixed.

Furthermore, the stirring device comprises at least two stirring structures, and the stirring structures move relatively or oppositely.

Further, the stirring structures are arranged in the same vertical direction.

Further, the stirring structures are arranged in a staggered mode in the vertical direction.

By adopting the structure, the asphalt mixing speed can be accelerated by stirring for many times.

Further, the stirring device comprises at least one pair of stirring structures which are oppositely arranged, and the stirring structures are arranged on the same horizontal direction.

Further, the two stirring structures move downwards relatively.

Further, a heating device is arranged on the stirring structure.

Further, the inner wall of the tank body is provided with a heating device.

Since the asphalt is easily cooled at a low temperature, the asphalt can be prevented from being cooled, resulting in a problem of uneven mixing due to the above-mentioned structure.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses a (mixing) shaft level sets up, makes the stirring leaf do clockwise or counter-clockwise motion in vertical direction, can be with adding jar internal, and powder or liquid material stirring on pitch surface to jar body below make jar internal pitch flash mixed even.
