Problems solved by technology

[0002] When the existing concrete mixing station is mixing, the aggregate, powder, water, and admixture are put into the mixing host together for mixing; with this mixing method, each material does not have the pre-mixing function, and the mixing efficiency and quality are poor ; and the existing mixing station, most of the aggregate and powder batching adopts the accumulative metering method, and the batching accuracy is poor; water and additives are mixed in the mixing chamber and then enter the mixer through the delivery pump, which has a complicated structure and increases the cost; therefore, In order to solve the above problems, there is a need for a mixing plant control method, a control device and a mixing plant

Embodiment 1

[0038] Such as figure 1 , figure 2 Shown, a kind of control method of mixing plant, this method comprises:

[0039] Step 1: The host computer issues control instructions, and the actuators of the lower computer are activated to enter the state of waiting for production;

[0040] Step 2: According to the needs of materials, modify the batching start and stop delay time of all levels of ingredients on the upper computer, and then set the mixing ratio on the upper computer and send it out. The aggregate bin and powder bin are opened, and the actuators of each lower computer The batching operation is carried out according to the setting of the mixing ratio; the batching instructions issued by the upper computer are executed through the lower computer to ensure that the aggregates are stacked sequentially on the aggregate collection belt conveyor, and the powder is pre-mixed in the powder feeding screw conveyor, water and The admixture is mixed in advance in the pipeline; the di...

Abstract

The invention discloses a control method and device and a mixing station. By the adoption of the control method, the different proportions of aggregate, powder, water and addition agents are controlled, so that mixing operation of concrete with different grades is achieved. According to the control method, premixing operation of the aggregate, the powder and the agents is achieved, and the mixingefficiency and the mixing quality are improved; the weight and flow dual measurement mode is adopted by the aggregate, the powder and the agents, the aggregate in an aggregate measurement temporary storage bin and the powder in a powder measurement temporary storage bin are subjected to secondary re-check correction, and therefore the batching accuracy is improved; and pre-mixing operation of thewater and the addition agents in a pipeline is achieved by a positive displacement pump and a centrifugal pump, a blending bin and a conveying water pump are not required, and the cost is saved. All in all, the control method and device and the mixing station fulfill the matched material pre-mixing function, saves the cost and improves the batching accuracy, the mixing efficiency and the mixing quality.

Description

technical field [0001] The invention relates to the technical field of mixing plants, in particular to a control method, a control device and a mixing plant. Background technique [0002] When the existing concrete mixing station is mixing, the aggregate, powder, water, and admixture are put into the mixing host together for mixing; with this mixing method, each material does not have the pre-mixing function, and the mixing efficiency and quality are poor ; and the existing mixing station, most of the aggregate and powder batching adopts the accumulative metering method, and the batching accuracy is poor; water and additives are mixed in the mixing chamber and then enter the mixer through the delivery pump, which has a complicated structure and increases the cost; therefore, In order to solve the above problems, a mixing station control method, a control device and a mixing station are needed. Contents of the invention [0003] The main purpose of the present invention is...
