Stirring station aggregate feeding system and control method

Abstract

The invention discloses a stirring station aggregate feeding system. The stirring station aggregate feeding system comprises a storage yard provided with a plurality of stock bins, a flat belt, an inclined belt, a material distribution belt, and a stirring station provided with a plurality of stock bins, wherein the material distribution belt can rotate forwards and reversely so as to realize blanking at the two ends, a plurality of discharge arc doors are arranged in the storage yard stock bins, each discharge arc door is provided with a material flow detection device, and the flat belt, theinclined belt and the material distribution belt are sequentially connected through transition hoppers; material blockage detection devices are arranged on the transition hoppers, the material distribution belt is arranged on a rail, a position detection device is arranged on the rail, a material level detection device used for detecting the height of the material level in each stock bin and an over-limit inspection devices arranged at the height limit positions are arranged in each stock bin of the stirring station. According to the system, only full inspection signals are arranged, and no material null signals are arranged, so that the loading condition is met as long as material full signals are not detected, and the system can effectively improve the feeding reliability, the working efficiency and the automation level.

Description

technical field [0001] The invention discloses a feeding system and a control method, in particular to an aggregate feeding system and a control method of a mixing station. Background technique [0002] In the concrete mixing plant, the aggregates (stones and sands of different specifications) for the production of concrete need to be stored and transported. Due to the huge demand for the aggregates used, a special large-scale storage yard is generally set up in the mixing plant. The specifications are stored separately. Due to the different types of concrete, the types of aggregates required are also different. Generally, 6-8 different types of aggregates are used in commercial concrete mixing plants, but in one type of concrete, the types of aggregates are generally There will be no more than 4 types, and the aggregate bins configured on all mixing stations are mostly 4 grids, which means that 4 types of aggregates are used at the same time. In order to improve the aggreg...

AI Technical Summary

Problems solved by technology

[0003] 1. The degree of automation is low, and manual or semi-automatic control is mostly used, and workers are labor-intensive to operate;

[0004] 2. The efficiency is low, limited by the speed of the cloth trolley, it takes a lot of time to switch the material bin;

[0005] 3. In the absence of necessary detection technology, accidents such as full warehouse, material blockage, and material shortage are prone to occur, which will affect concrete production;

[0006] 4. For multi-silo feeding, the replacement of silo varieties can only be done manually, which is prone to wrong material feeding;

[0007] 5. At present, an opening and closing detection switch is generally installed on the discharge arc door to check the opening and closing of the discharge arc door, but it is impossible to directly judge whether the discharge arc door is blocked, which will affect the feeding and thus affect the conveying capacity
