Bridge construction low-carbon asphalt mixing equipment with good heat preservation effect

Abstract

The invention discloses a bridge construction low-carbon asphalt mixing equipment with good heat preservation effect; the equipment comprises a bottom plate and a mixing tank, a proper amount of low-carbon asphalt is guided into the mixing tank, a motor, a hydraulic cylinder and an induced draft fan are started, a snakelike heating wire is electrified, the motor drives a rotating shaft to rotate, the low-carbon asphalt is stirred and mixed through a spiral stirring rod. A curved rod is driven to rotate, so that the mixing contact area of the low-carbon asphalt at the inner bottom and the inner side wall of the mixing tank is increased, the low-carbon asphalt collides with each other, and the mixing efficiency is improved; a heat conduction device is used for inputting heat into the stirred medium-low carbon asphalt, so that the low carbon asphalt is always kept at a proper temperature, and the low carbon asphalt keeps certain viscosity; a damping mechanism is adopted to buffer shaking generated in the operation process of the device, the operation stability and the safety are improved, a stainless steel skin arranged outside the mixing tank avoids heat loss, a time controller is arranged on the cover plate to effectively control the operation time, manual operation errors are avoided, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a mixing device, in particular to low-carbon asphalt mixing equipment for bridge construction with good thermal insulation effect. Background technique [0002] Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. In the process of bridge construction, it is necessary to lay a layer of carpet asphalt on the surface of the concrete bridge deck. It has good water permeability, is not easy to slip in rainy days, is resistant to high temperatures, will not melt in hot weather, and is easy to maintain. Low-carbon asphalt needs to be applied before paving. The raw materials are mixed and mixed by a mixing device. The existing mixing and stirring device mixes and mixes low-carbon asphalt. Due to the temperature loss of low-carbon asphalt, the viscosity d...

In the process of bridge construction, it is necessary to lay a layer of carpet asphalt on the surface of the concrete bridge deck. It has good water permeability, is not easy to slip in rainy days, is resistant to high temperatures, will not melt in hot weather, and is easy to maintain. Low-carbon asphalt needs to be applied before paving. The raw materials are mixed and mixed by a mixing device. The existing mixing and stirring device mixes and mixes low-carbon asphalt. Due to the temperature loss of low-carbon asphalt, the viscosity decreases, and the low-carbon asphalt will solidify into blocks, which is inconvenient for mixing and affects Low carbon asphalt mixing efficiency;

[0003] In the Chinese invention patent with the notification number CN207714079U, a road asphalt mixture mixing device is disclosed. A dispersing disc disc tooth-shaped dispersing disc is arranged under the stirring shaft. The dispersing disc is fixedly connected with the stirring shaft. The dispersing disc consists of two parts. , act on the asphalt on the left and right sides of the stirring shaft respectively, and its dispersing disc disperses the asphalt. It can be seen that the asphalt at the bottom and inner side wall of the mixing tank is still not in contact with the situation, there is uneven mixing, and the whole mixing tank shakes during operation, no protective measures are taken, there are certain safety hazards, and there is no timing device so that The mixing situation is completely based on personal feeling, and the mixing tank is not well insulated, which may lead to uneven mixing and reduce work efficiency
