Emulsified asphalt production equipment

Abstract

The invention provides emulsified asphalt production equipment, which comprises a colloid mill, a mixing tank, a hot water tank and a PLC (Programmable Logic Controller) control system, wherein the hot water tank is connected with the mixing tank through a hot water pipe which is provided with control valves at two ends; the outlet end of the mixing tank is connected with a liquid soap tank through a conveying pipe, so that mixed liquid soap is conveyed into the liquid soap tank for later use; meanwhile, the mixing tank can be used for mixing liquid soap continuously; the liquid soap tank is connected with the colloid mill through a liquid soap pipe to supply needed liquid soap to the colloid mill; the outlet end of the colloid mill is connected with a heat exchanger through a finished product conveying pipe; a water inlet pipe of the heat exchanger is connected with the hot water tank; a water outlet pipe of the heat exchanger is connected with the hot water pipe through a three-way valve; floating ball switches which are connected with the PLC control system are arranged in the hot water tank, the mixing tank and the liquid soap tank, and are used for transmitting acquired corresponding signals to the PLC control system; and the PLC control system is used for controlling the work of each tank. According to the emulsified asphalt production equipment, the automatic degree of entire equipment is raised, the working efficiency is increased, and production cost is lowered.

Description

technical field [0001] The invention relates to asphalt processing equipment, in particular to emulsified asphalt production equipment. Background technique [0002] At present, there are mainly the following disadvantages in the production of emulsified asphalt: (1) Generally, hot water and emulsifier are manually added to the blending tank for mixing and blending, which has a low degree of automation and cumbersome operation; During the deployment, the measurement of the amount of soap and asphalt added is not accurate enough, and the error of the product percentage is large; (3) The overall integration of the equipment is low, the installation and transportation are not convenient enough, and it is difficult to adapt to the harsh construction site; (4) The blending tank The soap solution is directly supplied for finished product production, and the new soap solution can only be prepared after the soap solution in the mixing tank is used up, which cannot be continuously mi...
