Embodiment Construction

[0033] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0034] Such as figure 1 As shown, the hopper-type automatic distributing device for a closed calcium carbide furnace of the present invention includes an annular rotating device 1 on which an AC motor 2 is installed, and the AC motor 2 can be used to automatically control the start-up of the annular rotating device 1 Stop and rotate speed, also be fixed with several storage hoppers 3 that can turn over automatically on the annular rotating device 1.

[0035] The method for realizing its flipping is: a hydraulic cylinder connected to the bottom of the storage hopper 3 is installed at the bottom of the storage hopper 3 close to the center of the ring rotation device 1, and the bottom of the storage hopper 3 is away from the center of the ring rotation device 1 through the rotating shaft. When the storage hopper 3 needs to be turned over, the PLC ...

Abstract

The invention provides a hopper type material distribution device for a sealed calcium carbide furnace and an automatic control method. The automatic control method is characterized in that automatic material distribution is conducted in the calcium carbide furnace production process according to the material level conditions of silos arranged on a furnace roof of the calcium carbide furnace, and meanwhile hoppers are subject to automatic material supplementation according to the material level conditions of the feeding hoppers of a distributor. The core thought is that a processor judges whether the silos are short of materials according to the material level conditions of all the silos arranged on the furnace roof of the calcium carbide furnace, and the material storage conditions of the hoppers of the distributor are collected; automatic blanking is conducted when the silos are short of materials and the material storage conditions of the hoppers of the distributor meet the material supplementation condition, and if the material storage conditions of the hoppers of the distributor do not meet the material supplementation condition, materials are added into the hoppers until the material supplementation conditions are met, and then material supplementation operation is conducted; all the hoppers are filled with materials when no silos on the furnace roof needs material supplementation, and the steps are cycled. The annular material distribution device is safe, stable and high in automation, and can achieve unmanned automatic feeding of the silos arranged on the furnace roof of the calcium carbide furnace.

Description

technical field [0001] The invention belongs to the technical field of smelting furnaces and the field of automatic control, and in particular relates to a hopper-type material distribution device and an automatic control method for a closed calcium carbide furnace. Background technique [0002] my country has become the world's largest producer and consumer of calcium carbide. The supply of raw materials is an important part of calcium carbide production, and a good supply of raw materials can improve the efficiency of calcium carbide production. In the raw material supply process of traditional calcium carbide furnaces, people are basically required to coordinate operations on the feeding site, and some people also need to manually process the delivered raw materials on site. However, a large amount of dust and noise will be generated during the transportation of raw materials, which will make the on-site environment of raw material supply relatively harsh. If people stay...
