Description
Technical Field
[0001] The utility model relates to the technical field of water pumps, and in particular to an anti-winding mechanism for a submersible reflux pump. Background Art
[0002] A water pump is a machine for conveying liquid or pressurizing liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. There are many types of water pumps, including submersible circulating submersible return pumps, which are widely used. Submersible circulating submersible return pumps are widely used in water treatment process flows, such as secondary mixed liquid return in sewage treatment plants, denitrification, denitrification and phosphorus removal, etc. They are also widely used in ground water supply and drainage projects that require micro-lift and large flow. Submersible return pumps are easily entangled by weeds during use. Therefore, the utility model proposes an anti-entanglement mechanism for submersible return pumps.
[0003] In the prior art, there is a submersible sewage pump with a built-in anti-winding device, such as the publication number CN216714737U, which specifically relates to the technical field of sewage pumps, including a casing, a connection cover is provided on the top of the casing, a motor is provided inside the casing, and an anti-winding mechanism is provided at the bottom of the casing, and the anti-winding mechanism includes a sealing disk provided at the bottom of the casing and matched with the casing. The utility model is provided with an anti-winding mechanism, and during the process of water extraction, the support rod and the dividing blade will rotate first, and the impurities such as fibers and water plants entering the water pump will be cut first. At the same time, the grinding impeller continues to rotate and contacts the conical internal section of the grinding groove. The grinding groove and the grinding impeller are used in coordination with each other to grind and reach the discharge standard, which can effectively prevent the impurities such as fibers and water plants from clogging the water pump, and no additional filter is required. It can effectively prevent the impeller from getting stuck and avoid motor overload, which is convenient to use.
[0004] The above patent proposes that the existing anti-winding mechanism for submersible reflux pumps is usually carried out by the mutual cooperation of the grinding groove and the grinding impeller for grinding, etc. However, during use, the crushing device is a single crushing device, and the crushing efficiency of the single crushing device does not meet the use standard. Long-term use reduces the crushing effect, thereby reducing the working efficiency of the device in crushing weeds, etc., and it is inconvenient to adjust the spacing between the crushing knives, resulting in failure to meet the crushing emission standards. Therefore, the utility model provides an anti-winding mechanism for a submersible reflux pump. Utility Model Content
