Asphalt mixing plant and cleaning system thereof

Abstract

The invention discloses a cleaning system which is used for cleaning a material gate (3) of an asphalt mixing plant, and comprises a lytic agent branch for providing an asphalt lytic agent and a spray nozzle (2) which is opposite to the material gate (3), as well as a gas supply branch for providing compressed gas, and an outlet of the gas supply branch and the outlet of the lytic agent branch are connected with an inlet of the spray nozzle (2). The cleaning system has high cleaning efficiency and convenient operation and can reduce the asphalt cleaning cost. The invention further provides the asphalt mixing plant comprising the cleaning system, and the utilization of the asphalt mixing plant can improve the quality of asphalt mixture, lead the production to be safer and realize higher reliability.

Description

technical field [0001] The invention relates to the field of asphalt cleaning, in particular to a cleaning system for asphalt mixing equipment. Furthermore, the present invention also relates to an asphalt mixing plant comprising the above-mentioned cleaning system. Background technique [0002] Asphalt mixture is uniformly mixed with stone, stone powder, asphalt and other raw materials. It is used to lay asphalt pavement and is often used in road construction. [0003] The asphalt mixer is a core component of the asphalt mixing plant, which is used to mix the asphalt mixture, and the mixed asphalt mixture is discharged out of the asphalt mixing plant through the material gate. As the asphalt mixture is composed of stone, stone powder and asphalt, it is inevitable that asphalt will adhere to the material door during discharge. If the asphalt is not cleaned in time after the shutdown, the asphalt will cool down and solidify, which will cause the material door to stick and fa...

AI Technical Summary

Problems solved by technology

[0006] 1) Because the material door is made of metal, the heat dissipation is fast and the heat loss is large. If you want to dissolve asphalt in a short time, the power of the heating equipment is relatively large, and the energy consumption is large;

[0007] 2) The temperature control requirements are high, because too high temperature will make the asphalt age and deteriorate, thus affecting the quality of the asphalt mixture

[0011] 1) In addition to asphalt, non-stubborn substances such as stone powder are also stained on the material door 15, which affects the dissolution effect and increases diesel consumption;

[0012] 2) The dissolved matter falls off automatically by gravity, and there is a phenomenon of incomplete shedding, which is easy to pollute the mixture and affect the quality of the mixture;

[0013] 3) This diesel cleaning method requires pressurization systems such as the diesel pump 11 to pressurize the diesel, and the cost is relatively high
