Description

Technical Field

[0001] The utility model relates to the technical field of impellers for submersible flowmakers, in particular to a stainless steel impeller for submersible flowmakers. Background Art

[0002] Submersible flowmakers are a type of mixing and low-speed flowmakers, and are mainly suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants. They produce strong water flows with low tangential flows, which can be used for water circulation in the pool and for creating water flows in the nitrification, denitrification and phosphorus removal stages. Impellers are installed at the output end of the submersible flowmakers.

[0003] The impellers of some existing submersible flow thrusters are mainly made of a flat structure, which has a poor flow-guiding effect, resulting in a large impact on the stainless steel impellers during operation; moreover, most of the existing stainless steel impellers are made of a single stainless steel material, resulting in poor corrosion resistance of the impellers. Therefore, we designed a stainless steel impeller for submersible flow thrusters. Utility Model Content

The horizontal plane of one end of the edge 203 close to the straight edge 201 is higher than the horizontal plane of one end of the first free edge 202 close to the straight edge 201. The end of the impeller 2 close to the lower connecting plate 1 is recessed inward, so that an arc-shaped groove is formed on the front of the impeller 2. While ensuring the force-bearing area, the impact on the stainless steel impeller during use can be effectively reduced. A reinforcing rib 3 is welded to the outer wall of the impeller 2 close to the recess, and the other side of the reinforcing rib 3 is welded to the outer wall of the lower connecting plate 1. The stability between the lower connecting plate 1 and the impeller 2 is enhanced by welding the reinforcing rib 3.

[0022] The specific usage and function of this embodiment are as follows:

[0023] When the utility model is used, the impeller 2 can be formed by sand casting through a casting process, and its straight edge 201 contacts the middle part of the outer surface of the lower connecting plate 1. The contact surface of the lower connecting plate 1 is a welding surface, and the straight edge 201 is a welding edge. The lower connecting plate 1 is welded to the impeller 2 through the straight edge 201. The first free edge 202 and the second free edge 203 are both arc-shaped. The horizontal plane of the end of the second free edge 203 close to the straight edge 201 is higher than the horizontal plane of the end of the first free edge 202 close to the straight edge 201, so that the end of the impeller 2 close to the lower connecting plate 1 is concave inward. The first free edge 202 and the second free edge 203 are both arc-shaped, so that the front of the impeller 2 forms an arc groove, which can effectively reduce the impact of the stainless steel impeller during use while ensuring the force-bearing area.
