Additive weighing device

Abstract

The invention discloses an additive weighing device which comprises a feeding device, a weighing hopper, a material leakage prevention device and a water scale hopper, wherein the feeding device is used for stirring and conveying an additive, the additive is added into the feeding device, the feeding device is guided into the weighing hopper for quantitative weighing, the weighed additive is guided into the water weighing hopper through the leakage-proof device, the weighing hopper is arranged at the output end of the feeding device in a communicating manner, the additive is quantitatively weighed through the weighing hopper, the weighing hopper is used for preventing the additive from splashing or overflowing during weighing, the material leakage prevention device is used for preventing an additive inside and outside the weighing hopper from leaking and falling into the water scale hopper by controlling the communication direction when the weighing hopper conducts weighing, and the additive is guided into the water scale hopper after the weighing hopper completes weighing, and the problems of leakage and overflow in the additive weighing process are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to an admixture weighing device. Background technique [0002] In the process of concrete production, it is often necessary to add admixtures to change the characteristics of the produced concrete, such as water reducers, air-entraining agents and pumping agents, which can improve the rheological properties of concrete mixtures, retarders, early strength agents and Accelerators can adjust the setting time and hardening performance of concrete, and air-entraining agents, waterproofing agents and rust inhibitors can improve the durability of concrete. Therefore, admixtures need to be widely used in concrete production. [0003] Chinese Invention Patent Publication No. CN213081889U, the utility model relates to the technical field of raw material mixing, in particular to a precise metering and batching device for a concrete mixing station, which can screen out large pieces...

AI Technical Summary

Problems solved by technology

[0004] However, the following problems exist in the current use process: the concrete admixture is a viscous liquid, and some varieties (such as air-entraining agents, etc.) are prone to foam during the flow process. Splashes are easy to occur during the batching and unloading process, causing environmental pollution and waste of materials, and when the batching fails, there is a risk of overflow in the scale hopper, which will cause concrete safety and quality accidents; when the discharge door of the scale hopper fails , there is a phenomenon that leakage material directly enters the mixer (or water scale), causing concrete safety accidents
