Automated replacing device of copper pipe horizontal continuous casting filter

Abstract

The invention provides an automated replacing device of a copper pipe horizontal continuous casting filter. The upper end of a hydraulic lifting device provided with a movable mechanism at the bottomis connected with a rack shell, a fixed shell of the rack shell is internally provided with a slide rail, a slide platform and a three-phase asynchronous motor, a driving large continuous wheel axle connected with the three-phase asynchronous motor is arranged on a movable shell, a driving large chain wheel is connected with a driven large chain wheel through a short chain, a coaxial small drivingchain wheel of each large chain wheel is connected with a small driven chain wheel, a chain slide block is fixed to each long chain, slide blocks are fixed to chain slide block grooves and are fixedly connected with mechanical arms, pull rods are arranged in the mechanical arms, and a clamping pawl at the lower end of the pull rods corresponds to the upper portion a foam ceramic filter in shape.By means of the automated replacing device, the filter can be replaced in continuous production, the filtering effect is not influenced, the liquid level can also be kept constant in the replacing process, and the production efficiency and the quality of a copper casting blank are greatly improved.

Description

technical field [0001] The invention relates to a copper tube horizontal continuous casting device, in particular to a copper tube horizontal continuous casting filter. Background technique [0002] In the process of horizontal continuous casting of copper tubes, the casting copper liquid flows from the melting furnace into the holding furnace, and finally enters the horizontal continuous casting crystallizer. The foam ceramic filter is placed in the copper liquid in the holding furnace to control the copper liquid. Filtration and purification, the purification effect has a considerable impact on the quality of the cast billet tube, the pressure of the liquid inlet of the crystallizer is unstable, and it is easy to cause the instability of the cast billet tube, and when the existing factory manufactures the copper cast billet tube, due to The casting copper liquid is a high-temperature liquid, and there are many problems in replacing the filter. The replacement work takes a ...

[0002] In the process of horizontal continuous casting of copper tubes, the casting copper liquid flows from the melting furnace into the holding furnace, and finally enters the horizontal continuous casting crystallizer. The foam ceramic filter is placed in the copper liquid in the holding furnace to control the copper liquid. Filtration and purification, the purification effect has a considerable impact on the quality of the cast billet tube, the pressure of the liquid inlet of the crystallizer is unstable, and it is easy to cause the instability of the cast billet tube, and when the existing factory manufactures the copper cast billet tube, due to The casting copper liquid is a high-temperature liquid, and there are many problems in replacing the filter. The replacement work takes a long time, is time-consuming and laborious, especially in a special environment such as high temperature, the replacement work is particularly inconvenient, and the liquid splash occurs during the replacement process. The splashed liquid will It will endanger the normal working personnel in the area and cause potential damage to other nearby equipment. Most factories adopt the method of stopping production and replacing, and some factories even adopt the method of not installing filters. These unreasonable operations will increase the cost of copper pipe casting. The scrap rate in the subsequent processing of the billet will bring huge economic losses to the factory
