A control method and control device for anti-overflow of asphalt station and asphalt station

Abstract

The invention provides a control method and device for preventing asphalt in an asphalt station from overflowing and the asphalt station and relates to the field of processing of asphalt mixtures. Thecontrol method for preventing the asphalt in the asphalt station from overflowing comprises the following steps of calculating the initial feeding frequency of each cooling bin according to aggregaterequirement data of each heating bin and the feeding capacity data of each cooling bin; judging whether or not the actual feeding frequency of each cooling bin needs to be corrected; if the actual feeding frequency of one corresponding cooling bin needs to be corrected, adjusting the feeding frequency of the cooling bin and controlling the cooling bin to run according to the adjusted feeding frequency, or controlling the corresponding cooling bin to run according to the corresponding initial feeding frequency if the actual feeding frequency of the corresponding cooling bin does not need to becorrected. The method can correct the actual feeding frequency and prevent overflowing of the asphalt or waiting for feeding.

Description

technical field [0001] The invention relates to the field of asphalt mixture processing, in particular to a control method and control device for anti-overflow in an asphalt station and an asphalt station. Background technique [0002] Asphalt station is mainly used for mass production of asphalt concrete complete sets of equipment, can produce asphalt mixture, modified asphalt mixture and colored asphalt mixture, etc., is the necessary equipment for the construction of expressways, graded roads, municipal roads, airports and ports. [0003] At present, in the production process of common asphalt stations on the market, the feeding speed of the cold silo does not match the actual demand very well. If the feeding speed is too slow, it may cause waiting materials and affect the production efficiency. If the feeding speed is too fast, it may cause overflow and waste aggregates and energy such as oil and gas. If the incoming materials are not standardized, there will be materia...

Problems solved by technology

[0003] At present, in the production process of common asphalt stations on the market, the feeding speed of the cold silo does not match the actual demand well

If the feeding speed is too slow, it may cause waiting materials and affect the production efficiency. If the feeding speed is too fast, it may cause overflow, waste aggregates and energy such as oil and gas.

If the incoming materials are not standardized, there will be material shifting during the production process, and the feeding speed of the cold material bin is not well matched with the actual demand, which will easily cause overflow or waiting materials.
