Casting knotting furnace pipe device capable of being operated conveniently and quickly and assembled and disassembled quickly

Abstract

The invention discloses a casting knotting furnace pipe device capable of being operated conveniently and quickly and assembled and disassembled quickly. The casting knotting furnace pipe device comprises a furnace pipe bottom. The lower end of the furnace pipe bottom is closed, the lower end of a cylindrical furnace pipe middle is arranged at the upper end of the furnace pipe bottom, and an upper cylindrical furnace pipe portion is arranged at the upper end of the furnace pipe middle; a sunken first stepped ring is arranged on the inner wall of the upper end of the furnace pipe bottom, and a protruded first secondary stepped ring is arranged at the lower end of the furnace pipe middle adjacent to the first stepped ring; a sunken second stepped ring is arranged on the inner wall of the upper end of the furnace pipe middle, and a protruded second secondary stepped ring is arranged at the lower end of the upper furnace pipe portion adjacent to the second stepped ring; fixing devices are respectively arranged between the first secondary stepped ring and the first stepped ring and between the second secondary stepped ring and the second stepped ring. The casting knotting furnace pipe device has the advantages that problems of extreme inconvenience in knotting operation and poor knotting compactness in the past can be solved, damage to the inner wall of a furnace can be prevented, the labor intensity of operators can be greatly reduced, and the work efficiency can be improved; the casting knotting furnace pipe device is low in manufacturing and maintaining cost and high in site universality, and the like.

Description

Technical field [0001] The invention is the field of casting and production equipment, and it is specific to involve a casting furnace bile device for casting. Background technique [0002] At present, in the production of castings, the metal melting process is performed by a melting furnace. After the melting furnace melted a certain amount of metal liquid, the inner wall of the furnace body will cause cracks and damage.The furnace is scrapped, and the furnace must be made regularly. When the furnace is built, the furnace body needs to be completely removed and re -built.The traditional furnace bile used in the traditional knot furnace cannot achieve convenient, fast loading and unloading in the furnace gallbladder, and during the knotting process, due to the cylindrical of the knot space, the cross section is small and deep (910-960㎜)The knot operation is extremely inconvenient, which not only causes the tightening of the tie to meet the requirements; it is very difficult to re...

AI Technical Summary

Problems solved by technology

The furnace used in the traditional knotting furnace cannot be easily and quickly loaded and unloaded in the loading and unloading of the furnace, and during the knotting process, because the knotting space is in the shape of a ring column, the cross section is narrow and the depth is very deep (910~960㎜) , the knotting operation is extremely inconvenient, which not only causes the tightness of the knotted body to fail to meet the requirements; it is also very difficult to take the furnace out of the furnace after the knot is completed, and it is entirely up to the operator to apply outward force on the furnace along the axis. The furnace is slowly released from the furnace body by force. Because the furnace is close to the inner wall of the furnace, it is necessary to manually apply a large force to remove the furnace from the furnace body. This operation process can easily lead to knotting. The inner wall of the smelting furnace is damaged, and the labor intensity of the operator is very high (the moving distance of the furnace is the height of the entire furnace body, which is 910-960 mm), and the work efficiency is extremely low
