Embodiment Construction
[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to provide a comprehensive understanding of the present invention, many details are described below, but it will be apparent to those skilled in the art that the present invention can be practiced without these details. Known components, methods and processes will not be described in detail below.
[0037] The invention provides a method for automatically adjusting a cold storage bin. Assuming that there are n hot silos, the number of cold silos and hot silos is also n, the hot silos are marked as Hot1, Hot2...Hotn; the cold silos are marked as Cold1, Cold2...Coldn, and the specifications of the hot silos Compare them one by one.
[0038] 1. Use the weighing method to calibrate each cold storage bin. refer to figure 1 , when the cold material bin is full, the inverter of the cold material motor is controlled by the programmable controller firs...

A method for automatically adjusting cold feed bins, comprising the following steps: 1. Calibrating each cold feed bin by a weighing method; 2. Calibrating the specifications of cold feed bins; 3. Setting the initial frequency of cold feed bins; The continuous material level gauge of the hot silo and its high and low positions are calibrated; five, the adjustment of the material level change; six, the high and low adjustment of the material level. The invention takes into account the non-standard cold material in the cold material bin, calculates the cold material formula through the target formula, uses the relationship between the total output and the cold material formula, determines the cold material bin frequency at the beginning of production, and finally passes the heat The cold material formula is automatically adjusted by the change of the silo position and the height of the hot material silo, which solves the problem of deviation between the actual supply of the cold material silo and the demand of the hot material silo due to the existence of non-standard materials in the cold material silo.
Description
technical field [0001] The invention relates to the technical field of asphalt production, in particular to a method for automatically adjusting a cold feed bin. Background technique [0002] Aggregate supply system of asphalt mixing plant, refer to Figure 11 , mainly consists of several cold material bins 10, collection belt 20, feeding belt 30, heating and drying equipment 40, hoist 50, hot material bin 60 and aggregate weighing scale 70, among which, several cold material bins 10 Various cold materials are installed respectively. At present, the adjustment of the flow rate of the cold material to the aggregate supply system is mainly realized by adjusting the frequency of the frequency conversion motor used to drive the discharge of the cold material bin to adjust the speed of the frequency conversion motor. If the speed of the frequency conversion motor decreases, the output of the cold storage bin will decrease proportionally; if the speed of the frequency conversion ...
