Combination Feeding Quantitative Scale

Abstract

The invention relates to a combined feeding quantitative scale. The large storage hopper is installed on the frame, the feeding belt is arranged directly below the discharge opening at the bottom of the large storage hopper, the feeding belt is driven by a belt feeding motor, and the lower hopper of the belt is arranged on the feeding port. The belt is directly below the normal feeding end; the metering hopper is set below the feeding port of the belt feeding hopper, and a pneumatic valve is installed at the outlet of the lower end of the metering hopper, and a metering sensor is installed on the metering hopper, and the metering sensor is connected to the control cabinet; the screw feeds The barrel is installed at the lower part of the small storage hopper, the screw feeding barrel is fixedly installed on the feeding support frame, the feeding support frame is installed on the frame through the feeding sensor, the screw feeding motor is installed at one end of the screw feeding barrel, and the screw feeding The other end of the cylinder is the feeding port, which is located above the measuring hopper, and the feeding sensor is connected with the control cabinet. The invention can automatically weigh the powder and the mixture of powder particles of the pressed refractory brick, improve the weighing efficiency and precision, improve the product quality, and improve the working environment.

Description

technical field [0001] The invention relates to a weighing device, in particular to a combined feeding quantitative scale for weighing refractory brick raw materials, and belongs to the technical field of refractory material manufacturing equipment. Background technique [0002] After the refractory bricks used in the iron and steel industry are formed, there are strict requirements on the technical indicators of the product such as density, weight, and size, and the raw materials need to be weighed and then pressed. The raw material of refractory bricks belongs to the mixture of powder and granules. After adding the binder, it has a certain humidity. The fluidity of the raw materials is poor, and it is easy to form arches and bridges. With different types of refractory bricks, the density and specific gravity of raw material formulas vary greatly. At present, the methods and disadvantages of weighing the weight of refractory brick raw materials in the industry are as follo...

AI Technical Summary

Problems solved by technology

At present, the methods and disadvantages of weighing the weight of refractory brick raw materials in the industry are as follows: 1. Manual weighing: high labor intensity, low efficiency, and serious dust pollution

2. Belt feeding and weighing: the weighing accuracy is low, which reduces the technical indicators of finished products, and is suitable for a narrow range of varieties

3. Volumetric weighing: the weighing error is large and the accuracy is low, because the raw material volume box is a part of the refractory brick mold, it is difficult to adjust the volume
