Embodiment Construction

[0028] Such as figure 1 As shown, the multi-tube splicing screw pump with high field range includes left sleeve (1), right sleeve (6), screw (19), reducer (20) and motor (21). The bottom of the multi-sleeve splicing screw pump is provided with a stirring device (18), the screw (19) is provided with a screw (22), and the left sleeve (1) and the right sleeve (6) are connected by a snap ring (7) Together. When the multi-sleeve splicing screw pump with high field range requires multiple sleeves for work, the multiple left sleeves (1) and right sleeves (6) are spliced ​​together end to end to form a sleeve of sufficient length . An air inlet (27) is provided on the upper end of the right sleeve (6). The air inlet (27) is connected to the vacuum pump (29) through the air inlet pipe (25), and the vacuum pump (29) is fixed on the base (26) On the building, there is an air outlet (30) on the right side of the vacuum pump (29). Because the vacuum pump (29) pumps air in the casing, the ...

Abstract

The invention provides a high-lift multi-sleeve-spliced screw pump. The high-lift multi-sleeve-spliced screw pump comprises a left sleeve, a right sleeve, a screw rod, a speed reducer, a vacuum pump and a motor; the high-lift multi-sleeve-spliced screw pump is characterized in that the bottom of the high-lift multi-sleeve-spliced screw pump is provided with a stirring device; the screw rod is provided with screw blades; the left sleeve and the right sleeve are connected with each other through a clamping ring; the right side of the left sleeve is provided with a left connecting ring; the lowerside of the left connecting ring is provided with an engaging groove; the vacuum pump communicates with an air inlet in the right sleeve through an air charging pipe; and the right side of the vacuumpump is provided with an air outlet. The high-lift multi-sleeve-spliced screw pump provided by the invention has the beneficial effects that the screw pump is provided with the vacuum pump, a negative-pressure environment is formed inside each sleeve, so the lift of the screw pump can be increased, and the sewage conveying efficiency is improved.

Description

Technical field [0001] The invention relates to the field of liquid transportation, in particular to a multi-sleeve splicing screw pump with high field range. Background technique [0002] The screw pump is mainly used for agricultural drainage and urban drainage. It is more suitable for sewage treatment plants to improve the return of sewage with sludge, but its head is low and the speed is slow. In contrast, it is suitable for water with more impurities wide range. There are also related patent publications in the Chinese patent database, such as: CN107061295A, CN106895004A. However, its field range is low, but due to its great advantage in sewage discharge, it can be used as a pipeline to accelerate the direction of sewage discharge. The extension of the tube is limited, which requires splicing and assembly. The existing tube splicing generally uses two pipes to be fastened by bolts. Because the tube is heavier, the splicing is difficult, and it is easy to cause sewage leakag...
