Problems solved by technology

[0003] Sewage pumps are also used in fermentation tanks, but the existing sewage pumps, when working, produce high-speed motor noise, which seriously affects the physical and mental health of the staff, and cannot filter out impurities in the sewage, and the sewage pumps are easily blocked by impurities In addition, some existing sewage pumps with filter screens will adhere to a large amount of debris after long-term use. If they are not cleaned in time, the filter screens will be blocked, and the existing sewage pumps will not work When the impeller rotates, it will form a tangential vortex, which will cause a certain amount of energy loss, thereby affecting the efficiency of the sewage pump.

Abstract

The invention provides a sewage pump special for a fermentation tank, and relates to the field of sewage pumps. The sewage pump comprises a pump body. In the sewage pump, a servo motor is started to drive a rotary rod to rotate, thus, a first impeller and a second bevel gear are driven to rotate, two third bevel gears are driven to rotate, the third bevel gears are engaged with a first bevel gear,a bearing outer ring is driven to rotate, thus, a second impeller is driven to rotate, the rotating directions of the first impeller and the second impeller are opposite, vortexes generated when thetwo impellers rotate are mutually offset, energy losses caused by the vortexes are reduced to be minimal, and therefore the efficiency of the sewage pump is higher. The third bevel gears drive connecting rods to rotate, thus, cams are driven to rotate, movable rods are driven to reciprocate back and forth through springs and rolling balls, L type rods are connected with the outer surface of the top of a filter plate, pull rods are connected with the inner bottom surface of the filter plate, thus, the filter plate is driven to swing all the time, and dirt is treated in time.

Description

technical field [0001] The invention relates to the field of sewage pumps, in particular to a special sewage pump for fermentation tanks. Background technique [0002] The sewage pump is a kind of centrifugal impurity pump. There are many types of sewage pumps, the common ones are horizontal sewage pumps and vertical sewage pumps. Compared with horizontal sewage pumps, vertical sewage pumps are widely used because of their small size, simple manufacture, and low cost. should be used. [0003] Sewage pumps are also used in fermentation tanks, but the existing sewage pumps, when working, produce high-speed motor noise, which seriously affects the physical and mental health of the staff, and cannot filter out impurities in the sewage, and the sewage pumps are easily blocked by impurities In addition, some existing sewage pumps with filter screens will adhere to a large amount of debris after long-term use. If they are not cleaned in time, the filter screens will be blocked, a...
