A mixing device

Abstract

This application provides a mixing device, relating to the field of material mixing technology, including a mixing chamber, a stirring mechanism, and a baffle mechanism. The mixing chamber has an inlet pipe at its upper end and a discharge pipe at its lower end. The stirring mechanism has n+1 groups, and the baffle mechanism has n groups, where n≥1. The baffle mechanism is located between two adjacent groups of stirring mechanisms. The baffle mechanism includes a guide slope relatively disposed inside the mixing chamber, a sealing plate installed at the lower end of the guide slope, and cylinders relatively disposed on the outer wall of the mixing chamber. In use, the mixing device provided by this application uses a motor to drive the stirring components to rotate, which stir the material. After stirring, two cylinders drive the sealing plates to move, and the material falls through the area between the two sealing plates, where it is stirred again by the lower stirring mechanism. This multiple stirring process improves the uniformity of the mixture. Since the operation of each stirring zone is independent, the intermediate waiting time is shortened, and work efficiency is improved.

Description

Technical Field

[0001] This application relates to the field of material mixing technology, and more specifically, to a mixing device. Background Technology

[0002] As a major solid waste from the steel industry, steel slag is used in the cement industry as an important way to realize its resource utilization. This not only conforms to the concept of circular economy, but also reduces cement production costs and environmental impact. Steel slag is mainly used as a cement admixture, an iron correction material for clinker production, and a concrete admixture (steel slag powder). Before use, steel slag needs to be fully mixed with other raw materials.

[0003] Existing mixing devices typically involve first feeding various materials separately into the mixing tank, and then mixing them to achieve uniform mixing. However, since materials tend to separate into layers inside the mixing tank when they are fed separately, and the materials have limited fluidity, more time is required to mix them, which affects the mixing efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a mixing device that can solve the technical problem of low material mixing efficiency.

[0005] This application provides a mixing device, including a mixing box, a stirring mechanism, and a material blocking mechanism. The upper end of the mixing box is provided with a feed pipe, and the lower end of the mixing box is provided with a discharge pipe. The stirring mechanism is provided in n+1 groups, and the material blocking mechanism is provided in n groups, where n≥1. The material blocking mechanism is located between two adjacent groups of the stirring mechanism.

[0006] The material blocking mechanism includes a guide slope disposed opposite to the inside of the mixing box, a sealing plate slidably installed at the lower end of the guide slope, and a cylinder disposed opposite to the outer wall of the mixing box. The cylinder drives the sealing plate to move left and right.

[0007] The stirring mechanism includes a motor and a stirring assembly. The motor is located on the outer wall of the mixing chamber, and the stirring assembly is located inside the mixing chamber. The motor drives the stirring assembly to rotate.

[0008] Preferably, the material blocking mechanism further includes a guide block disposed at the bottom of the material guiding slope, the guide block being provided with a guide groove, and a connecting rod being disposed between the sealing plate and the cylinder, the connecting rod being movably inserted through the guide groove.

[0009] Preferably, the stirring assembly includes a rotating rod and a plurality of stirring rods, one end of the rotating rod is rotatably connected to the inner wall of the mixing chamber, the other end of the rotating rod passes through the mixing chamber, and the rotating rod is connected to the motor.

[0010] Preferably, the mixing box includes n+1 boxes, with flange connections between adjacent boxes, the feed pipe being located on the uppermost box, and the discharge pipe being located on the lowermost box.

[0011] Preferably, the lower end of the mixing box has a funnel-shaped structure.

[0012] Preferably, the discharge pipe is equipped with a discharge valve.

[0013] Preferably, the lower end of the mixing box is provided with multiple support legs.

[0014] The beneficial effects of this utility model are:

[0015] In use, the mixing device provided in this application feeds the materials to be mixed into the mixing chamber through the feed pipe. The motor drives the stirring component to rotate, and the stirring component stirs the materials. After stirring, two cylinders drive the sealing plates to move, so that the two sealing plates move away from each other. The materials fall through the area between the two sealing plates and are stirred again by the stirring mechanism below. Through multiple stirrings, the uniformity of the material mixing is improved. After the materials above the sealing plates are discharged, the cylinders drive the sealing plates to move, and the two sealing plates seal the area between the two guide slopes again. At this time, the materials to be mixed can be fed into the mixing chamber again. Since the work of each stirring area does not affect each other, the intermediate waiting time is shortened and the work efficiency is improved. Attached Figure Description

One end of the rotating rod 14 is rotatably connected to the inner wall of the mixing box 1, and the other end of the rotating rod 14 passes through the mixing box 1.
