Intelligent pneumatic driving sewage lifting device

Abstract

The invention discloses an intelligent pneumatic driving quantitative lifting device. The intelligent pneumatic driving quantitative lifting device comprises a cylindrical pump body, a gas pipe quick joint arranged at the top of the cylindrical pump body, a control valve body connected with the gas pipe quick joint through a nylon hose and an intelligent controller connected with the control valve body through wire harnesses; and the cylindrical pump body is internally provided with an air pressure type sewage lifting mechanism. According to the intelligent pneumatic driving quantitative lifting device, an aeration fan of a sewage treatment device is utilized to provide gas source drive without additional power addition; the structure is simple, no moving part exists, no maintenance is needed, and installation and using are convenient; the lifting height of the device depends on the pressure of driving gas and is not affected by the submerged depth, when the lifting amount is the same, the gas consumption is much lower than that of a gas lifting device, and theoretically, the same volume of liquid can be lifted by the same volume of gas; the intelligent controller can set the operating frequency of a solenoid valve in place or through wireless network, and the lifting amount can be adjusted within a larger scale; and the lifting amount can be adjusted quantitatively and continuously between 2L / h and 1000L / h so as to adapt to different sewage treatment capacities.

Description

technical field [0001] The invention relates to a pneumatically driven quantitative lifting device, in particular to a device suitable for lifting sewage of small-scale decentralized rural sewage treatment equipment, backflowing, sludge discharge, and lifting toxic, flammable and explosive liquids or solid-liquid mixtures in other industries. Background technique [0002] With the development of society, the rural economy develops rapidly, and the living standard of farmers has been greatly improved. However, the construction of rural environment is not in sync with economic development, and the problem of water environment pollution is particularly serious. [0003] To protect and improve the rural environment, for scattered farmers, it is advisable to adopt small-scale decentralized sewage treatment with low energy consumption. For small-scale decentralized sewage treatment equipment, the treatment capacity is between 0.5 tons / day and 20 tons / day, and the sewage lifting pum...

AI Technical Summary

Problems solved by technology

[0004] The flow rate of the conventional electric sewage lifting pump is much greater than the processing capacity of the equipment, which will cause impact on the water intake of the equipment, and the flow rate cannot be quantitatively adjusted according to the processing capacity; Frequent maintenance and replacement

[0005] Conventional air lift and pulse air lift technology are mature and have a long history, and have been widely used in sewage treatment equipment, but there are still many shortcomings: conventional air lift has a small lifting height, cannot meet the demand for higher lift, and works unstable under low flow conditions. The lifting amount cannot be adjusted quantitatively; although pulse air lifting has improved lifting efficiency and small flow stability, the essence of air lifting is to use the difference in density inside and outside the riser to achieve liquid lifting, which requires a high submersion rate (>60%) Only in order to achieve lifting, the lifting height is limited
