Abstract

The invention relates to the technical field of steel fiber concrete processing equipment, in particular to a steel fiber distribution bin, a steel fiber metering distribution system and a control method. The steel fiber metering distribution system is characterized by comprising a steel fiber storage device, a steel fiber feeding device and the steel fiber distribution bin, the steel fiber feeding device is used for conveying steel fibers in the steel fiber storage device into the steel fiber distribution bin, and the steel fiber distribution bin is installed on a distribution rack through a weighing sensor and located right above an aggregate conveyor. The whole structure is novel and reliable, the steel fiber storage bin is smooth in discharging, a steel fiber conveyor can continuously, stably and slowly supply materials to the steel fiber distribution bin, the weighing accuracy of the steel fiber distribution bin is facilitated, the steel fiber distribution bin is arranged right above the aggregate conveyor, and the steel fibers are uniformly and fully scattered on the aggregate conveyor, so that the steel fibers and the aggregate are uniformly and fully premixed.

Description

technical field [0001] The invention relates to the technical field of steel fiber concrete processing equipment, in particular to a steel fiber distribution bin, a steel fiber metering distribution system and a control method. Background technique [0002] Steel fiber reinforced concrete is a new type of multiphase composite material formed by adding disorderly distributed steel fibers into ordinary concrete. It improves the tensile, flexural, impact and fatigue resistance of concrete, and has good ductility. The traditional method of mixing and feeding is to manually pour the bagged steel fibers into the hopper or conveyor belt, which leads to The steel fiber does not have accurate measurement accuracy, the steel fiber is not scattered and directly put into the mixing drum for uneven mixing or the phenomenon of steel fiber clumping. It can also cause local strength weakening. [0003] In order to solve this problem, a steel fiber batching device is provided in the invent...

Problems solved by technology

Yet this steel fiber also has following some deficiencies: 1, due to the characteristic of steel fiber, it is slender and irregular, fluidity is poor, because this storage hopper is just a bucket body, and the first electromagnetic vibrating feeder is only installed in the storage hopper Below, due to the poor fluidity of the steel fiber itself in the storage hopper, it will cause the storage hopper to be unsmooth when it is discharged to the first electromagnetic vibration feeder; 2. Since the weighing hopper is directly fed by the first electromagnetic vibration The feeder is used for feeding, and the feeding speed and feeding amount of the first electromagnetic vibrating feeder cannot be well controlled, so that the accuracy of weighing in the weighing hopper cannot be well guaranteed; 3. After weighing in the weighing hopper The steel fiber is fed to the conveyor belt of the mixing station batching machine through the second electromagnetic vibration feeder. Since the second electromagnetic vibration feeder is set on one side of the batching machine conveyor belt of the mixing station for feeding, so that after weighing The steel fibers cannot fall well on the center line of the conveyor belt of the batching machine in the mixing station, and the drop point of the steel fibers cannot be well guaranteed. This will easily lead to uneven conveying weight on the conveyor belt of the batching machine in the batching station, thus It causes the belt to deviate, and even makes the steel fiber spill out of the belt. At the same time, it cannot ensure that the dispersed steel fiber and the aggregate conveyed on the belt are evenly and fully pre-mixed, thus affecting the mixing effect of steel fiber concrete.
