A water tank waste water lifter for reverse osmosis system

Abstract

The invention discloses a water tank waste water lifter for a reverse osmosis system. The water tank waste water lifter comprises a driving device and a water pumping device and is characterized in that the driving device comprises a shell, an impeller is rotationally arranged in the shell, and the side wall of the shell is communicated with a water inlet pipe and a water outlet pipe; the water pumping device comprises a lining and a screw rod forming a sealing cavity with the inner wall of the lining, a water return pipe communicated with the water outlet pipe is arranged at the upper end of the lining, a water inlet for waste water of a water tank is formed in the lower end of the lining, and a driving shaft is connected between the impeller and the upper end of the screw rod. According to the water tank waste water lifter for the reverse osmosis system, rotation of the impeller is driven under kinetic energy of tap water, the impeller drives the screw rod to rotate through the driving shaft, the pumping capability on the waste water of the water tank is achieved, the pumped waste water is mixed in the water outlet pipe for tap water, and therefore the waste water is stored in a cold water tank for use, and zero emission of the waste water is achieved; in addition, an electric pump is not used, the waste water is lifted, and the energy-saving feature is achieved.

Description

technical field [0001] The invention relates to a lifter, in particular to a water tank waste water lifter used in a reverse osmosis system. Background technique [0002] The basic working principle of the reverse osmosis system (RO) is to use a special high-pressure water pump to increase the raw water to a pressure of 6 to 20 kg, so that the raw water can permeate through the reverse osmosis membrane with a pore size of only 0.0001 micron under the action of pressure. Among them, chemical ions Bacteria, fungi, and virus bodies cannot pass through, and are discharged with wastewater, and only water molecules with a volume smaller than 0.0001 microns are allowed to pass through, so as to achieve the purpose of water purification. [0003] However, there is an inevitable defect in the existing reverse osmosis systems, that is, in the process of producing pure water, a large amount of waste water is generated, while the traditional waste water treatment is directly discharged ...

Problems solved by technology

[0003] However, there is an inevitable defect in the existing reverse osmosis systems, that is, in the process of producing pure water, a large amount of waste water is generated, while the traditional waste water treatment is directly discharged through the drainage pipe; or the waste water is collected in the water tank, Electric pumps are used to transport the wastewater to the treatment station

Direct discharge of waste water causes excessive waste of water resources, and the use of electric pumps for transportation consumes a lot of electric energy, resulting in waste of energy
