Description

Technical Field

[0001] The utility model relates to the technical field of anode furnace gas mixing chambers, in particular to a casting tool used for casting inner walls of gas mixing chambers. Background Art

[0002] In traditional copper pyrometallurgy, the inner part of the anode furnace's mixing chamber is a layer of heat-resistant castable. The pouring process of this castable is generally to manually support the template inside the mixing chamber and pour it in sections. First, make the bottom template and then do the bottom pouring operation, then make the upper template and then do the upper pouring operation. This process can complete the pouring of the inner wall of the entire mixing chamber in multiple times. Because the mixing chamber is small and the workload of supporting the template is relatively large, the entire construction period is relatively long; in addition, each layer is supported by a wooden template, and the inner wall of the casting is uneven and not smooth enough. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a pouring tool for pouring the inner wall of a gas mixing chamber.

[0004] The specific scheme of the utility model is as follows: a pouring tool for pouring the inner wall of a mixing chamber, comprising two semi-cylinders, the two semi-cylinders are combined into a whole cylinder, a group of cross-shaped support rods are respectively installed at both ends of the cylinder, the two ends of the cross-shaped support rods are connected to the corresponding semi-cylinders by bolts, and a hook for hanging a rope is installed at one end of the cylinder.

[0005] Preferably, the group of cross-shaped support rods includes two support rods that are perpendicular to each other and staggered, each end of the support rod is provided with a plane, a threaded hole is provided on the plane, the inner wall of the semi-cylinder is provided with a fixing block corresponding to the end of the support rod, the fixing block is provided with a through hole aligned with the threaded hole, and the two ends of the support rod are connected to the fixing block by bolts.

[0006] Preferably, the pull hook comprises a straight rod portion and a curved hook portion, one end of the straight rod portion is welded to the end surface of the semi-cylinder, and the curved hook portion is arranged toward the center of the cylinder.

[0007] Preferably, the semi-cylinder has a thickness of 3-6 mm and a height of 1.2-1.5 m.

[0008] Preferably, the diameter of the support rod is 4-6 mm.

[0009] Preferably, the semi-cylinder is made of stainless steel.

[0010] Compared with the prior art, the utility model has the following beneficial effects: 1. The utility model can replace the method of using wooden formwork to support the formwork, thereby improving the efficiency of the pouring operation and shortening the entire pouring operation cycle of the inner wall of the mixing chamber; 2. It can make the pouring inner wall of the mixing chamber flatter and smoother. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1-3 As shown, this embodiment provides a casting tool for casting the inner wall of a mixing chamber, including two semi-cylinders 1 made of stainless steel, the thickness of the semi-cylinder 1 is 3-6 mm, and the height is 1.2-1.5 m. The two semi-cylinders 1 are combined into a whole cylinder, and a group of cross-shaped support rods 3 are respectively installed at both ends of the cylinder. The two ends of the cross-shaped support rods 3 are connected to the corresponding semi-cylinders 1 by bolts 5, and one end of the cylinder is evenly installed with four hooks 2 for hanging ropes.

[0017] Preferably, the group of cross-shaped support rods 3 includes two support rods 3 that are perpendicular to each other and staggered, the diameter of the support rod 3 is 4-6 mm, and a plane is provided at each end of the support rod 3, and a threaded hole is provided on the plane. The inner wall of the semi-cylinder 1 is provided with a fixing block 4 corresponding to the end of the support rod 3, and the fixing block 4 is provided with a through hole aligned with the threaded hole, and the two ends of the support rod 3 are connected to the fixing block 4 by bolts 5.

[0018] Preferably, the draw hook 2 comprises a straight rod portion and a curved hook portion, one end of the straight rod portion is welded to the end surface of the semi-cylinder 1, and the curved hook portion is arranged toward the center of the cylinder. Figure 4The specific method of using this embodiment to perform the pouring operation on the inner wall of the mixing chamber is as follows: the first step is to assemble the two semi-cylinders 1 of the utility model and the cross-shaped support rods 3 at both ends, and apply a layer of grease to the outer wall of the cylinder; the second step is to place the mixing chamber shell 6 vertically on the workbench, and then place the cylinder assembly prepared in the first step on the bottom of the mixing chamber shell 6, and make the center of the cylinder coincide with the center of the mixing chamber shell 6; the third step is to hang a lifting rope on each of the four hooks 2, and connect the other ends of all the lifting ropes to the lifting device; the fourth step is to perform the first pouring: pour the heat-resistant material into the area between the mixing chamber shell 6 and the cylinder, and after cooling and solidification, demould the cylinder upwards through the lifting device; the fifth step is to apply a layer of grease to the outer wall of the demolded cylinder, put it back into the mixing chamber shell 6 for the second pouring operation, and repeat this several times until the inner wall of the mixing chamber is completely cast and formed.

[0019] It should be noted that if demoulding is difficult in the fifth step, in order to avoid deformation of the cylinder, the bolts 5 connecting the support rod 3 and the fixing block 4 can be removed first, and then the two semi-cylinders 1 can be peeled off and taken out, and then assembled outside.
