Abstract

The invention relates to the technical field of pumps, in particular to an industrial sewage pump which comprises a motor, a transmission gear, a connecting ring, side scraping plates, a side feedingport, a first side scraper, a second side scraper, a rotating ring, movable cutters and a bottom feeding port. The motor drives the transmission gear to rotate so as to drive a gear ring and the connecting ring to rotate; the connecting ring rotates to drive the at least two side scraping plates to rotate, the side scraping plates rotate to scrape impurities attached to the side feeding port, theside feeding port is prevented from being blocked, the first side scraper can cut the impurities, the added second side scraper improves the cutting effect, and therefore the preliminary cutting function of the side feeding port is achieved; and the side scraping plates rotate to drive the rotating ring to rotate at the same time, a side T-shaped groove formed in a cam line rotates along with therotating ring, and the movable cutters at different positions can be driven to do telescopic motion, so that the movable cutters are used for cutting impurities entering from the bottom feeding port,and the primary cutting function of the bottom feeding port is achieved.

Description

technical field

[0001] The invention is an industrial sewage pump, which belongs to the technical field of pumps. Background technique

[0002] The sewage pump is a kind of pump product in which the pump and the motor are integrated and submerged into the liquid at the same time. Compared with the general horizontal pump or vertical sewage pump, the sewage pump has a compact structure and a small footprint. Installation and maintenance are convenient. Large sewage pumps are generally equipped with automatic coupling devices for automatic installation. Installation and maintenance are quite convenient. Long continuous operation time. Because the pump and the motor are coaxial, the shaft is short and the rotating parts are light, so the load (radial) on the bearing is relatively small, and the service life is much longer than that of ordinary pumps. There is no problem of cavitation damage and water diversion. Especially the latter point brings great convenience to the oper...

Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] see Figure 1-Figure 6 , the present invention provides a technical solution: an industrial sewage pump, including a pump main body 1, a sewage inlet 2 is provided at the lower end of the pump main body 1, and a filter screen 21 for filtering sewage is fixed at the lower part of the annular inner wall of the sewage inlet 2 to avoid Impurities that are too large in volume enter the pump main body 1 to reduce the probability of clogging inside the pump main body 1. The lower end of the impeller in the sewage inlet 2 is fixed with a scraper mechanism 20. The scraper mechanism 20 penetrates the filter screen 21 up and down and extends to the lower part of the filter screen 21. , the scraping mechanism 20 can rotate with the impeller, thereby sc...
