Liquid feeding device with connecting portion with radially long and narrow grooves and buffer limit pipe section

Abstract

The invention relates to a device which is used for feeding a liquid by utilizing air pressure and is provided with a buffer limiting pipeline section and a radially-extending connecting part with a radial long and narrow slot. The device comprises a pressure air feeder (7), a pressure chamber (8), a pressure supply pipe (9), a liquid feeding pipeline (10) and an absorbing and filtering device (20), wherein the pressure air feeder (7) is used for providing pressure for the pressure chamber (8) by the pressure supply pipe (9); the pressure chamber (8) is used for pressurizing the liquid in the pressure chamber (8) and sending out the pressurized liquid by the liquid feeding pipeline (10); the absorbing and filtering device (20) is arranged at the inner side end of the liquid feeding pipeline (10) and is used for filtering the liquid which is absorbed from the pressure chamber (8) by the liquid feeding pipeline (10); the liquid which is sent out can flow at the outer side end of the liquid feeding pipeline (10); 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...

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
