Description

Technical Field

[0001] The invention relates to the technical field of submersible pumps, and more particularly to an anti-clogging submersible pump for sewage discharge. Background Art

[0002] The submersible pump is one of the sewage conveying equipment. The common submersible pump is mainly composed of a pump body, an impeller, a pump shaft, a motor and other mechanisms. The specific working process of the submersible pump is as follows: when the motor is started, the pump shaft and the impeller are driven to rotate at high speed through the coupling. At this time, the blades on the impeller, under the action of centrifugal force, throw the liquid inside the pump body to the surroundings, forming a high-speed rotating liquid ring. Due to the action of centrifugal force, the liquid forms a low-pressure area in the center of the impeller, so that the liquid is continuously sucked into the pump body; at the same time, the thrown liquid passes through the flow channel of the pump body and is pushed to the outlet to complete the liquid conveying process;

[0003] When the submersible pump is performing sewage discharge operations, there is a certain amount of impurities in the sewage. The impurities enter the submersible pump and cause certain damage to its internal components. Therefore, in order to avoid the above situation, in the prior art, a filter plate is installed at the input end of the submersible pump to filter impurities, thereby protecting the submersible pump from working normally. However, in actual operation, we found that if the water contains a large amount of solid particles or impurities, the filter plate is easily blocked, resulting in a decrease in the efficiency of the pump or even failure to work normally, thereby causing certain economic losses. In this case, manual cleaning is required to ensure that the filter plate works normally. Therefore, this process requires a certain amount of manpower waste. At the same time, during the impurity filtering process, the impurities constantly hit the surface of the filter plate, resulting in excessive wear on the surface of the filter plate, which in turn causes the filter plate to be unable to perform the sewage impurity filtering operation normally, thereby causing certain damage to the internal components of the submersible pump, thereby causing certain economic losses.

The electric-controlled adsorption device 306 generates an adsorption force to limit the new filter plate 105. After the limit is completed, the electric-controlled stretching device 307 controls the new filter plate 105 to enter the middle position of the two groups of annular hollow plates 106, thereby completing the replacement operation of the damaged filter plate 105. After the damaged filter plate 105 is replaced, the electric-controlled lifting device 308 inputs current to control the adsorption disc 309 to move toward the direction of the electric-controlled valve 302, so that the staff can place the qualified filter plate 105 on the surface of the adsorption disc 309. The micro air pump 310 inputs current to generate adsorption force, which is transported to the surface of the qualified filter plate 105 through the adsorption disc 309 and the adsorption hole 311 to perform the limit operation. After the qualified filter plate 105 is limited, the electric-controlled lifting device 308 returns to its original position, which is convenient for the replacement device 3 to perform the next filter plate 105 replacement operation.
