Embodiment 1

[0031] Such as figure 1 As shown, it is a schematic flow chart of a concrete feeding and mixing method provided by an embodiment of the present invention. This method is applied to a mixing station, and the figure 1 Visible, this method comprises the following steps:

[0032] Step S101: Control the material conveying device to successively convey the fine aggregate and the coarse aggregate to the intermediate warehouse for temporary storage.

[0033] Here, the conveying device refers to a material handling machine that continuously conveys materials on a certain line, also known as an assembly line. The conveying line can carry out horizontal, inclined and vertical conveying, and can also form a space conveying line, and the conveying line is generally fixed. In traditional mixing plants, flat belts and inclined belts are usually used to convey materials. Among them, fine aggregate is an aggregate with a relatively small diameter. It is a granular loose material that acts a...

Embodiment 2

[0048] The embodiment of the present invention aims at the difference in the delivery order of fine aggregate and coarse aggregate, and introduces a feasible intermediate warehouse structure, wherein, the intermediate warehouse includes at least two compartments, and the fine aggregate can be placed The material and coarse aggregate are transported to the two compartments separately and stored independently. These two bins can have their own independent bin doors, which are controlled by the control system. When feeding for the first time, the door of the bin storing fine aggregate is opened for the first feeding, and for the second feeding. , then control to open the door of the cell where the coarse aggregate is stored. In addition, these two compartments can also share a compartment door, when the fine aggregate is put into the mixing machine, the coarse aggregate is not unloaded, and when the coarse aggregate is put in, the fine aggregate is not unloaded.

[0049] The con...

Embodiment 3

[0051] Embodiments of the present invention also provide a concrete feeding and mixing device, such as image 3 As shown, the device includes a sequentially connected feeding module 31, a duration receiving module 32, a first feeding module 33, a second feeding module 34 and a stop module 35, wherein the functions of each module are as follows:

[0052] The feeding module 31 is used to control the material conveying device to successively convey the fine aggregate and coarse aggregate to the intermediate warehouse for temporary storage;

[0053] The duration receiving module 32 is configured to receive the first feeding duration, the second feeding duration, the first stirring duration and the second stirring duration input by the user;

[0054] The first feeding module 33 is used to start the mixing main engine to stir, control the intermediate warehouse to perform the first feeding, and control the storage warehouse to put a predetermined amount of gelling material into the ...

Abstract

The invention provides a batch feeding and stirring method for concrete and a device and relates to the technical field of stirring station control. The method comprises the steps: controlling a material conveying device to convey fine aggregates and coarse aggregates into a midway cabin for temporary storage successively; receiving user input first batch feeding duration, second batch feeding duration, first stirring duration and second stirring duration; starting up a stirring host to carry out stirring, controlling the midway cabin to carry out first-time batch feeding, and controlling a storage cabin to feed a predetermined amount of cementing material into the stirring host, wherein the duration of the first-time batch feeding is the first batch feeding duration; controlling the midway cabin to carry out second-time batch feeding when the stirring time reaches the first stirring duration, wherein the duration of the second-time batch feeding is the second batch feeding duration; controlling the stirring host to stop stirring when the stirring time reaches the second stirring duration. According to the batch feeding and stirring method for the concrete and the device, providedby the embodiments of the invention, the load of the stirring host during mixing can be reduced, the production efficiency is increased, and the occurrence of blockage is reduced.

Description

technical field [0001] The invention relates to the technical field of mixing station control, in particular to a concrete feeding and mixing method and device. Background technique [0002] Concrete is usually made by using cement as the cementitious material, sand and stone as the aggregate, mixed with water (may contain admixtures and admixtures) in a certain proportion, and then mixed. As a mass production of concrete equipment, mixing plants are widely used in various construction engineering fields. [0003] Among them, the concrete mixing plant is mainly composed of material storage system, material weighing system, material conveying system, mixing host, electrical control system and other auxiliary facilities. Among them, the material storage system includes the batching machine sand storage hopper, cement silo, water tank, admixture liquid storage tank, etc.; the material weighing system includes the batching machine sand scale, cement scale, water scale, and admi...
