Mixing apparatus capable of realizing dynamic metering and proportioning

Abstract

The invention discloses a mixing apparatus capable of realizing dynamic metering and proportioning. The mixing apparatus comprises a mixing tank, a speed-regulating delivery pump, a spiral conveyer, a weight-measuring, metering and proportioning control instrument, two transition bunkers and a weighing device, wherein a conveying pipeline arranged between the speed-regulating delivery pump and one of the two transition bunkers is provided with a flowmeter and a base material pulse transmitter, the spiral conveyer is connected with the other of the two transition bunkers and is provided with an accessory material pulse transmitter and a raster transmitting disc, the two transition bunkers are mounted on the weighing device, the weighing device is fixed on the mixing tank, and the transition bunkers are communicated with the mixing tank. The weighing device comprises a stationary lever which inclines to start an alarm when a weight ratio of a base material to an accessory material in the two transition bunkers does not accord with a predetermined ratio; and the weighing device can directly detect whether the weight ratio of the flowing base material to the flowing accessory material accords with the predetermined ratio, so the problem of inaccuracy of the weight ratio of the base material to the accessory material obtained by measuring flow in the prior art is overcome.

Description

technical field [0001] The invention relates to the application technical field of industrial automation metering ratio, in particular to a dynamic metering ratio mixing device. Background technique [0002] In the continuous processing of mixed materials in industrial production, static metering is used for metering control, which not only restricts the increase in production, but also leads to the complexity of the operation process, and also increases the manufacturing cost and failure rate of the equipment. In this regard, the utility model with the application number of 200520100592.0 discloses a continuous dynamic metering and proportioning mixing device, which belongs to the application technical field of industrial automatic metering and proportioning. Tank, speed-adjustable conveying pump with flow meter and base material pulse transmitter, screw conveyor with buffer silo and speed-adjustable motor, auxiliary material pulse transmitter with grating sending disc, and...

AI Technical Summary

Problems solved by technology

[0006] The technical problem solved by the present invention: during the continuous processing of the mixed material in industrial production, the weight ratio (proportion relationship) is calculated by continuously and dynamically measuring the flow of the base material and the auxiliary material. Or powder, the density per unit volume of the base material and the auxiliary material is not constant, resulting in an inaccurate weight ratio calculated from the flow rate
