Continuous metering device for liquid tin in heat-preservation melting pot

Abstract

A continuous metering device for liquid tin in a heat-preservation melting pot comprises a bearing foundation, the heat-preservation melting pot, a bearing ring, a weighing sensor, a fixing plate, a water tank, a sealing ring, a combustor, a smoke exhaust pipeline, a junction box, a weighing instrument and a DCS. The bearing foundation is an annular columnar bearing foundation with a bottom, and the bearing foundation is horizontally arranged; the edge of the heat-preservation melting pot is arranged on the bearing foundation; the bearing ring, the weighing sensor, the fixing plate, the watertank and the sealing ring are arranged between the bearing foundation and the edge of the heat-preservation melting pot, the combustor is arranged at the lower part of the bearing foundation, and thesmoke exhaust pipeline is arranged at the upper part of the bearing foundation and at the end far away from the combustor; and the weighing sensor, the junction box, the weighing instrument and the DCS system are connected in sequence. According to the invention, liquid tin can be directly metered in the pot without being transferred and weighed, so that the energy loss of heat-preservation moltentin is avoided; and through the structural connection design of the water tank and the sealing ring, smoke is directly prevented from leaking, the working environment is ensured, and the service lifeof the measuring device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metallurgy weighing equipment, and in particular relates to a continuous metering device for liquid tin in a heat preservation melting pot. Background technique [0002] In the centrifugal de-impurity process, the first and second tin in the smelting furnace are roughly treated and then enter the heat preservation melting pot, and then directly flow into the refining workshop through the tin pipeline for processing. Refining workshop processing. Because the tin transport channel has a certain distance, in order to ensure the fluidity of rough tin in the tin transport channel, a temperature control system must be installed in the heat preservation melting pot to control the temperature of the heat preservation melting pot; the heat preservation melting pot of the present invention adopts a burner to control the temperature. Control, a crude tin measurement has become an urgent problem to be so...

AI Technical Summary

Problems solved by technology

[0003] At present, the common method of measuring crude tin is to use a tin transport trolley to load liquid tin into the trolley and push it to the track scale for weighing. This method cannot heat the trolley and cause energy loss after transferring to the next process; At the same time, it is easy to leak liquid tin when it is transferred under high temperature, which will cause safety accidents of personnel and equipment, and it will not achieve the purpose of continuous measurement.
