Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydrometallurgy and relates to a multi-tooth type follow-up defoamer. Background Art
[0002] In the nickel matte oxygen pressure leaching process, a large amount of foam is generated in the second-stage atmospheric leaching tank, which is likely to cause the slurry to overflow from the tank and high-temperature scalding. It is necessary for the on-site personnel to constantly patrol and add defoamers for metallurgical mining to suppress foam to maintain production. The use of defoamers increases high-molecular organic substances in the nickel sulfate solution, which are not easily degraded and are prone to enrichment, directly affecting the production quality of the final nickel product. Therefore, adopting a physical and mechanical defoaming method to reduce the dependence on defoamers for metallurgical mining is one of the research directions of technicians. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a multi-tooth type follow-up defoamer for solving the problems existing in the prior art, that is, the use of existing defoamers increases high-molecular organic substances in the nickel sulfate solution, which are not easily degraded, are prone to enrichment, and easily affect the production quality of the final nickel product.
[0004] For this reason, the utility model adopts the following technical solutions:
[0005] A multi-tooth type follow-up defoamer includes a hub, and tooth frames are symmetrically arranged on both sides of the hub. Along the horizontal direction, a T-shaped defoaming tooth, a needle-shaped defoaming tooth, and an F-shaped defoaming tooth are sequentially arranged on the tooth frame, and all three are perpendicularly connected to the tooth frame, with the T-shaped defoaming tooth being closest to the hub.
[0006] Further, the horizontal teeth of the T-shaped defoaming tooth and the horizontal teeth of the F-shaped defoaming tooth are both in the same direction as the extension direction of the tooth frame, and the three are located on the same horizontal plane.
[0007] Further, the T-shaped defoaming tooth, the needle-shaped defoaming tooth, and the F-shaped defoaming tooth are arranged at equal intervals and in parallel.
[0008] Further, the lengths of the T-shaped defoaming tooth, the F-shaped defoaming tooth, and the needle-shaped defoaming tooth decrease in sequence.
[0009] Further, the tops of the T-shaped defoaming tooth and the F-shaped defoaming tooth are at the same height and are located on the same horizontal plane. The upper tooth height of the needle-shaped defoaming tooth is 1 / 2 of the upper tooth height of the T-shaped defoaming tooth; the bottoms of the F-shaped defoaming tooth, the needle-shaped defoaming tooth, and the T-shaped defoaming tooth extend downward in sequence, and the three are located on the same oblique line.
[0010] Further, the three tooth ends of the F-shaped defoaming tooth, the two tooth ends of the needle-shaped defoaming tooth, and the three tooth ends of the T-shaped defoaming tooth are all in a needle tip shape.
[0011] The beneficial effects of the utility model are as follows:
[0012] The utility model adopts a physical and mechanical defoaming method, which reduces the usage amount of defoamer and the inspection frequency of adding defoamer at the post, reduces the labor intensity at the post and the defoamer content in the nickel sulfate solution, improves the quality of the nickel sulfate solution, and does not require an additional power source, thus being energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a structural schematic diagram of the utility model.
[0014] In the figure, 1 - tooth frame, 2 - T-shaped defoaming tooth, 3 - needle-shaped defoaming tooth, 4 - F-shaped defoaming tooth, 5 - hub. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The technical solution of the utility model will be described in detail below in conjunction with the drawings and the embodiments.
[0016] As Figure 1 shown, a multi-tooth type follower defoamer includes a hub 5, tooth frames 1 are symmetrically arranged on both sides of the hub 5, a T-shaped defoaming tooth 2, a needle-shaped defoaming tooth 3 and an F-shaped defoaming tooth 4 are sequentially arranged on the tooth frame 1 in the horizontal direction, and the three are perpendicularly connected to the tooth frame 1, and the T-shaped defoaming tooth 2 is closest to the hub 5.
[0017] Among them, the T-shaped defoaming tooth 2, the F-shaped defoaming tooth 4 and the needle-shaped defoaming tooth 3 are located on the same horizontal plane, the three are arranged at equal distances and in parallel, and the lengths decrease in turn; in addition, the three tooth ends of the F-shaped defoaming tooth 4, the two tooth ends of the needle-shaped defoaming tooth 3 and the three tooth ends of the T-shaped defoaming tooth 2 are all needle-shaped.
[0018] Specifically, the top of the T-shaped defoaming tooth 2 and the top of the F-shaped defoaming tooth 4 are at the same height and are located on the same horizontal plane, and the upper tooth height of the needle-shaped defoaming tooth 3 is 1 / 2 of the upper tooth height of the T-shaped defoaming tooth 2; the bottom of the F-shaped defoaming tooth 4, the bottom of the needle-shaped defoaming tooth 3 and the bottom of the T-shaped defoaming tooth 2 extend downward in turn, and the three are located on the same oblique line.
[0019] The using process of the utility model is as follows:
[0020] First, the utility model is installed on the stirring shaft close to the pulp liquid level of the second-stage atmospheric leaching tank through the hub 5. Since the initially generated foam accumulates around the stirring shaft of the second-stage atmospheric leaching tank, the lower tip of the T-shaped defoaming tooth 2 first plays a defoaming role; then, as the foam continues to be generated, the enriched foam gradually spreads around. Since the lower tips of the F-shaped defoaming tooth 4, the needle-shaped defoaming tooth 3 and the T-shaped defoaming tooth 2 gradually shorten in length as the linear velocity increases, the three cooperate to jointly complete the defoaming function; finally, when the foam layer continuously thickens until it exceeds the tooth frame 1, the horizontal teeth of the T-shaped defoaming tooth 2 and the horizontal teeth of the F-shaped defoaming tooth 4 can still continue to effectively defoam and suppress foam, maintaining the defoaming effect.
