Embodiment 1

[0030] figure 2 A uniform distribution device for a sintering cup provided by the present invention, the distribution device includes a feed inlet 1, a funnel-shaped feeding pipe 2, a transmission motor 4, a central drive shaft 5, and a discharge port 3; the funnel-shaped feeding pipe 2 has a horn The upper end of the mouth is the feed port 1, and the lower end of the detail is the discharge port 3; the transmission motor 4 is fixed on the center above the bell mouth of the funnel-shaped feeding pipeline 2 through the support frame 7, and the lower part of the transmission motor 4 is connected to the central drive shaft 5; The central drive shaft 5 extends along the central axis of the funnel-shaped feed pipe 2 to the discharge port 3, and there are three pairs of helical blades 6 continuously distributed thereon. Lifting lug 8 is installed on funnel-shaped feeding pipeline 2 trumpet edges. In addition, in order to prevent the central drive shaft 5 from swaying, an anti-shak...

Embodiment 2

[0033] Use the sintering cup uniform distribution device described in Example 1 to carry out cloth sintering.

[0034] The iron ore powder, fuel, and solvent used for sintering are weighed and proportioned according to the requirements, mixed evenly, moistened with water, and pelletized to form a mixture. First hang the uniform distribution device to the sintering cup, and then add the mixture to the distribution device. Lift at a constant speed of 400 mm / min, and turn on the motor at the same time, so that the central drive shaft drives the mixture through the blade at a speed of 30 r / min, so that the height of the mixture outlet and the surface of the mixture placed in the sintering cup is maintained at 50mm , and evenly distribute it into the sintering cup at a flow rate of 30-35 kg / min. When lifting the uniform distribution device to distribute the material, the distance between the discharge port and the surface of the mixed material in the sintering cup is maintained at...

Abstract

The invention discloses a uniform material distributing device and a corresponding material distributing method for a sintering cup. The uniform material distributing device for the sintering cup comprises a feeding opening, a funnel-shaped feeding pipeline, a transmission motor, a central driving shaft and a discharging opening, wherein the horn-opening-shaped upper end of the funnel-shaped feeding pipeline is the feeding opening, and the thin lower end of the funnel-shaped feeding pipeline is the discharging opening; the transmission motor is fixed in the center above the horn opening of the funnel-shaped feeding pipeline through a supporting frame, and the lower portion of the motor is connected with the central driving shaft; the central driving shaft extends to the discharging opening along the axis of the funnel-shaped feeding pipeline, and a spiral blade is distributed on the central driving shaft; lifting lugs are arranged at the edge of the horn opening of the funnel-shaped feeding pipeline. According to the uniform material distributing device and the corresponding material distributing method for the sintering cup, the uniformity of mixed material distribution is effectively improved, the reproducibility and the accuracy of the experiment result of the sintering cup are guaranteed, and the work environment conditions and labor intensity of operators are also improved.

Description

technical field [0001] The invention belongs to the technical field of sintering tests, and in particular relates to a sintering cup uniform distribution device and a corresponding distribution method. Background technique [0002] The conformity of the test results of the sintering cup has always been a subject of concern to the sintering workers. The uniformity of the sintering cup cloth has a great influence on the sintering cup test results. If the cloth is not uniform, the air permeability of the material layer will change, resulting in the inconsistency of the vertical sintering speed along the height direction, so that the burning speed is uneven during the sintering process. As a result, the strength, yield and utilization factor of the sinter are reduced, and the economic indicators of the sinter technology and the conformity of the test results of the sinter cup are affected. In order to avoid this phenomenon, it is required that during the sintering cup test, th...
