Description

A lime furnace mixing and batching device

technical field

The utility model relates to a mixing and batching device for a lime furnace.

Background technique

A lime furnace is used in the alumina production process. At present, in the lime furnace process production mixing system, the method of weighing with a scale and feeding with an electric vibrator is generally used to complete the mixing work. The measurement error is very large, up to 2 % or more, the most critical thing is the uneven mixing of materials, which not only causes high fuel consumption, but also serious lime burning and overburning, which can reach about 30%, which has a great impact on subsequent production.

Contents of the invention

The purpose of this utility model is to provide a kind of lime that can effectively solve the uneven mixing of materials, low measurement accuracy, high fuel consumption and heavy equipment maintenance workload existing in the lime furnace mixing process. Furnace mixing batching device.

The purpose of this utility model is achieved through the following technical solutions.

A mixing batching device for a lime furnace, characterized in that the batching device includes a raw material bin, an electronic belt scale, a mixing funnel, and a mixing bin; the raw material bins are arranged side by side at intervals, and one is installed below the outlet of the raw material bin by frequency conversion. The belt scale controlled by speed regulation is provided below the feeding end of the belt scale, and a mixing hopper is arranged across the space between the feeding ends of the two belt scales, and the feeding port of the mixing hopper is connected with the mixing bin.

The device of the utility model realizes the simultaneous start and stop of two kinds of materials through the electronic belt scale, and makes the mixed materials enter the mixing bin through the mixing hopper. In the process, the metering accuracy of the materials is greatly improved and the coke and Limestone is thoroughly mixed.

Description of drawings

Fig. 1 is the structural representation of the utility model device.

Detailed ways:

A mixing batching device for a lime furnace, the batching device includes a raw material bin 1, an electronic belt scale 2, a mixing funnel 3 and a mixing bin 4; In the belt scale controlled by frequency conversion, a mixing hopper is arranged under the feeding end of the belt scale across the space between the feeding ends of the two belt scales, and the feeding port of the mixing hopper is connected with the mixing bin.

The warehouse is built according to the amount of raw materials, and the capacity of the warehouse is determined by the capacity of the lime furnace and the mixing ratio of the stored materials. An electronic belt scale is installed under the raw material bin, and the electronic belt scale controls the mixing speed of the two materials through the frequency conversion speed regulation control system. A mixing funnel is installed between the two electronic belt scales to make the mixing more uniform. And install the mixing silo under the mixing funnel. After the materials in the two raw material bins are measured by the electronic belt scale, the mixing speed of the materials is adjusted by the frequency conversion speed regulation control system. The two materials enter the mixing funnel evenly at the same time, and the materials enter the mixing bin after mixing. The electronic belt scale uses frequency conversion speed control to realize the simultaneous start and stop of two materials, and makes the mixed materials enter the mixing bin through the mixing hopper. In the process, the measurement accuracy of the materials is greatly improved and the coke and limestone are fully obtained Mix to achieve uniformity and stability of the mixed ingredients.

Claims (1)
