1. Each cylinder, control valve and motor shall operate according to the requirements of concrete mixing process. The control of each cylinder, control valve and motor must be accurate, stable and reliable. From the manufacturer of loading concrete mixer, it can transport the concrete produced by the mixing plant (station) or the aggregate (sand, stone), cement and water mixed according to the proportion. In the process of transportation, the wet material is continuously mixed slowly to prevent the initial setting and segregation of concrete in the process of transportation.
The control system has two working modes, automatic and manual, which are independent and restrict each other.
2. The system has a good anti-interference ability and perfect alarm self-protection management function;
3. Through the communication with the computer, it can display the management status of the information system and give an alarm;
The mixer host system should be cleaned at least once in a working cycle. At the end of daily production activities, the information of mixer host should be cleaned comprehensively. The method is as follows: in the process of cleaning service, put water and a little stone into the mixer host, and mix for 5-10 minutes. After cleaning, all materials in the mixer should be effectively removed without ponding and accumulation; After shutdown, the pipes and pipes shall be washed to remove the dust inside and outside the mixing tank and the adhered concrete. In general, about 150-180kg of water is added between the main machines of the mixing equipment. The main machines of other product models can analyze the increase or decrease according to this, and they can also provide their own high-pressure water gun or carry out data cleaning.
When washing the material door of the main mixer, it should be avoided that the material accumulated under the upper part of the mixer will form a foreign body blocking the material door. In the process of mixing, if the concrete truck is not in place for a long time (more than 20-30min, especially in summer), water should be added to the mixer for simple cleaning.
During the normal production of the mixer, the concrete setting in the mixing drum and on the mixing shaft should be checked regularly. If there is any setting, it should be removed manually in time according to the requirements. Before manually cleaning the mixing drum, the power supply and gas path must be cut off, the residual gas must be discharged, and the control room must be locked; When manually cleaning the mixing drum, it is strictly forbidden to strike the mixing shaft, mixing arm and mixing blade violently.
Automatic feeding mixer with flushing charging door, upper flushing to avoid the phenomenon of clamping in the charging door formed by the accumulation of foreign materials when the mixing host equipment. During mixing, if there is no longer a truck in cast-in-place concrete (more than 20? 30 minutes, especially in summer), water should be added to the mixer for easy cleaning.
