Reverse osmosis valveless filtering basin

Abstract

The invention relates to a reverse osmosis valveless filtering basin which is provided with a flushing water tank, a water feeding and distributing trough and a water drainage water sealing well, wherein the water feeding and distributing trough is connected with a siphon rising pipe through a water feeding pipe; the siphon rising pipe is connected with a filtering device; the other end of the siphon rising pipe is connected with a siphon falling pipe; the siphon falling pipe is arranged in the water drainage water sealing well; a siphon damage pipe and a siphon auxiliary pipe are arranged at a joint of the siphon rising pipe and the siphon falling pipe; one end of the siphon damage pipe is connected with a siphon damage hopper; the siphon damage hopper is arranged in the flushing water tank; a water discharging pipe is arranged at the upper end of the flushing water tank; one end of the siphon auxiliary pipe is arranged in the water drainage water sealing well. The reverse osmosis valveless filtering basin is simple in structure, can realize automatic filtering and automatic repeated flushing and is convenient to operate, manage, assemble and disassemble; pipelines are high in corrosion resistance; the water loss is reduced, so that backwashing is realized; the backwashing effect is good, the automation degree is good, water resources are saved, and the cost is lowered.

Description

technical field [0001] The invention relates to a reverse osmosis valveless filter tank. Background technique [0002] Reverse osmosis technology is a membrane separation technology, which is used in conjunction with the pre-treatment system; using high-pressure pump pressure and reverse osmosis membrane interception, it can effectively remove impurities such as dissolved solids, organic matter, colloids, microorganisms and bacteria in water. It has a wide range of applications, a high degree of automation, a small footprint, low energy consumption, and good water quality. Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Apply pressure to the feed liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will permeate against the direction of natural permeation. Thus, the permeated solvent is obtained on the l...

Problems solved by technology

[0003] The structure of the existing filter tank is complicated, the filter material is in a closed structure, and it is difficult to load and unload. At the same time, the cost of the tank body is relatively high. The water loss is aggravated, and in serious cases, backwashing cannot be realized because all the incoming water is lost through the siphon
