Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sewage lifters, and specifically relates to a sewage lifter with a crushing device. Background Art
[0002] Sewage lifts are mainly used to remove sewage from sanitary ware in basements and places far away from drainage risers that do not have gravity discharge of sewage. They can also be used in ships, vehicles and other places where drainage conditions are not very good. In particular, the toilet or washbasin in the bathroom is located lower than the height of the city drainage pipe. An auxiliary sewage lift is especially needed to lift the sewage from the bathroom to a certain height and then discharge it into the city drainage pipe.
[0003] The patent application with announcement number CN213296623U discloses a sewage lifter with a crushing device, including: a shell, a crushing trough, a transmission shaft, a blade, a screen plate one, a connecting hole, a crushing chamber, a fixing seat, a spring, a gasket, a scraper, a screen plate two, a connecting pipe head, a lifting chamber, an impeller, a motor, a mounting chamber, a flat key, a keyway, a movable sleeve and a thrust ball bearing; the rotating blade in the utility model can crush the sewage and debris that first enter the crushing trough, thereby improving the crushing efficiency; the spring is provided in the utility model, which can ensure that the rotating scraper is closely attached to the screen plate two to cut and crush the debris, thereby avoiding the blockage of the sieve holes in the screen plate two, and also improving the sewage lifting effect.
[0004] However, the above-mentioned comparative documents have the following disadvantages when used:
[0005] From the description in paragraph 0017 of the above-mentioned comparative document, “When in use, first start the motor 16 to drive the transmission shaft 3 to rotate, and the rotation of the transmission shaft 3 drives the blade 4, the scraper 11 and the impeller 15 to rotate together, and the rotating blade 4 can firstly crush the sewage and debris entering the crushing tank 2, thereby improving the crushing efficiency, and then enter the crushing chamber 7 through the sieve plate 5 and the connecting hole 6”. It can be seen that the debris crushed by the blade 4 needs to be filtered through the sieve plate 5, and when the sieve plate 5 is screening the impurities, it is easy to cause the problem of impurities accumulating on the inner wall of the sieve plate 5, which reduces the efficiency of the sieve plate 5 in filtering the crushed debris.
[0006] Therefore, a sewage lifter with a crushing device is proposed to solve the above-mentioned drawbacks. Utility Model Content
