Depth detection device for high-temperature molten iron

Abstract

A depth detection device for high-temperature molten iron belongs to the technical field of high-temperature molten iron detection devices. According to the invention, a sensor is protected by using ahigh-temperature thermal insulation material, the sensor can resist 200 DEG C for 5 minutes, and the internal temperature of the sensor is always kept at about 50 DEG C. A blue laser is emitted to the liquid level position through an emitter and receives an image through a receiver. Image algorithm processing is carried out to obtain molten iron liquid level height data. When detection is needed,a pneumatic sliding table automatically extends out of a fixed sensor, returns to the original point after detection and is far away from the furnace opening, and the furnace opening is vacated at low temperature to facilitate work of a mechanical arm. Data obtained after laser detection are transmitted back to an industrial personal computer, the liquid level of molten iron is screened out through an image processing algorithm and then distributed to the mechanical arm, and molten iron casting work is conducted. When the furnace needs to be added with materials, cleaned or replaced, a sliding table fixing buckle is manually loosened, the sliding table and the whole set of equipment are pushed to move to the farthest end of double linear guide rails, so that the furnace is cleaned conveniently, and the detection device is protected.

Description

technical field [0001] The invention relates to a depth detection device for high-temperature molten iron, and belongs to the technical field of high-temperature molten iron detection devices. Background technique [0002] At present, for the cast iron industry, because the melting temperature of molten iron exceeds 1500°C, it is impossible to directly measure the depth with electronic sensors or mechanical sensors. In the absence of depth data, the workpiece is cast at high temperature, because with the reduction of molten iron, the mechanical arm cannot be accurately extended to the correct position. Previously, the descending height of the robotic arm was estimated by dividing the volume of the furnace by the volume of the casting ladle. However, in many cases, the molten iron is not quantitative, so many casting industries cannot be automated. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior a...
