Liquid supplying device with electroplating coating central shaft and rolling ball thrust bearing

Abstract

The invention discloses a device for supplying liquids by utilizing air pressure with an electroplating coating central shaft and a rolling ball thrust bearing. The device comprises a pressure air supplying device (7), a pressure chamber (8), a pressure supplying pipe (9), a liquid discharge pipeline (10) as well as a drawing / filtering device (20), wherein the pressure air supplying device (7) is used for providing pressure for the pressure chamber (8) by the pressure supplying pipe (9); the pressure chamber (8) can pressurize liquid in the pressure chamber (8) and discharge the liquid by the liquid discharge pipeline (10); the drawing / filtering device (20) is arranged at the inner side end of the liquid discharge pipeline (10) and is used for filtering the liquid when the liquid discharge pipeline (10) draws liquid from the pressure chamber (8); the outer side end of the liquid discharge pipeline (10) is used for discharging the liquid in a flowing mode; and the top of the pressure chamber (8) is provided with a liquid inlet (81).

Description

technical field [0001] The invention relates to a device for supplying liquid by air pressure, and more particularly relates to a device for supplying liquid by air pressure which can automatically remove flocs. Background technique [0002] The device that uses air pressure to give liquid is a kind of equipment that sprays liquid widely used in agriculture, green land maintenance and industry. The water quality used by the device that uses air pressure to give liquid varies according to the water source. Therefore, in order to prevent the device that uses air pressure to give liquid from being affected by impurities in the liquid, the device that uses air pressure to give liquid The end of the draw line often has a filter structure. [0003] However, due to the suction formed by the device that uses the air pressure to give the liquid during operation, it is easy to absorb a large amount of impurities near the end of the liquid delivery pipeline; Over time, these floccule...

AI Technical Summary

Problems solved by technology

However, in some cases, such as the maintenance of urban lawns, devices that use air pressure to deliver liquid need to draw liquid streams from some alternate liquid source, such as recycled rainwater, greywater, or even untreated ground surface Runoff water, and these devices that use air pressure to give liquid do not have the conditions for regular manual maintenance. Therefore, in this case, it is urgent to remove impurities to ensure the normal operation of the device that uses air pressure to give liquid. need
