Blowing additive metering system

Abstract

The invention discloses a blowing additive metering system, which belongs to a metering system. The structure of the system comprises an additive scale. The additive scale comprises a scale body, a scale body discharging butterfly valve and a sensor assembly. The sensor assembly comprises a sensor and a sensor terminal box, wherein the senor and the sensor terminal box are connected; and the sensor is arranged on the top part of the scale body. The scale body discharging butterfly valve is arranged at the bottom of the scale body. The upper part of the scale body is provided with a clearing pipe and an upper additive pipe which has an upper additive valve, wherein the upper additive pipe is divided into two paths. The additive scale is connected with a blowing additive device. The blowing additive metering system has the characteristics of radically preventing the instability of the main body structure from influencing the accuracy of the additive metering, improving the accuracy of the additive metering, solving the problem that the additive aggregates in a main machine and form insoluble particles, reducing stirring time, lowering use and electric cost of equipment, along with high efficiency, reliable metering accuracy, energy conservation and environmental friendliness.

Description

technical field [0001] The invention relates to a metering system, in particular to an air blowing admixture metering system. Background technique [0002] At present, the admixture metering system commonly used in China has irreparable defects due to the limitation of the structure and concrete production process: First, because of the structural layout, the admixture metering system is generally arranged in the main structure of the mixing station Firstly, the metering accuracy of the admixture is restricted by the stability of the main structure, and the vibration of the main structure during concrete production is difficult to eliminate, so it is difficult to ensure the metering accuracy of the admixture; the second is that the admixture metering system is arranged in the main body of the mixing station In terms of structure, it is generally more than 8 meters above the ground, and the admixture is sent to the scale body for measurement through the pump, which requires a...

[0002] At present, the admixture metering system commonly used in China has irreparable defects due to the limitation of the structure and concrete production process: First, because of the structural layout, the admixture metering system is generally arranged in the main structure of the mixing station First, the measurement accuracy of the admixture is restricted by the stability of the main structure, and the vibration of the main structure during concrete production is difficult to eliminate, so it is difficult to ensure the measurement accuracy of the admixture; the second is that the admixture measurement system is arranged in the main body of the mixing station In terms of structure, it is generally more than 8 meters above the ground. The admixture is sent to the scale body through the pump for measurement, which requires a large pump power; third, the unloading admixture is generally unloaded into the host by self-flow or water pump pressurization, so as to The liquid form enters the main machine, so that the admixture is easy to "cluster" in the main machine to form insoluble particles, and the mixing time needs to be prolonged to meet the homogeneity requirements of concrete
