Abstract

The utility model discloses quartz sand filtering equipment, which adopts a filtering mode of matching a water inlet pipe and an inner pipe, and in the filtering process, water enters a lower layer from an upper layer of quartz sand through the water inlet pipe and the inner pipe, so that water flow can fully contact with the quartz sand, the contact time of the water and the quartz sand is effectively prolonged, the absorption and decomposition efficiency of the quartz sand on suspended dirt in the water is greatly improved, the integral filtering effect is improved, and the purified water quality is ensured to reach higher standards. In the back flush function, through the reasonable arrangement of the branch pipe, the water inlet pipe, the drain outlet and the corresponding valve, the first valve is opened, the second valve is closed, and the third valve is opened during back flush, water enters the inner cavity of the filtering cylinder body through the water inlet pipe and the branch pipe, so that quartz sand is comprehensively flushed, dirt trapped in the quartz sand can be thoroughly flushed, and the dirt is smoothly discharged through the drain outlet, thereby not only improving the back flush efficiency, but also effectively protecting the quartz sand, prolonging the service life of the quartz sand and reducing the running cost of equipment.

Description

Quartz sand filtering equipment Technical Field The utility model relates to the field of water filtering treatment equipment, in particular to quartz sand filtering equipment. Background In the field of water treatment, quartz sand filtering equipment is widely applied to links such as industrial production, drinking water purification, sewage treatment and the like. Quartz sand is a common medium for filtering suspended impurities and colloid substances in water due to its good chemical stability and high mechanical strength. However, the existing quartz sand filtering equipment has a plurality of defects in the actual use process. Part of equipment is unreasonable in structural design, and the filtration efficiency is low, can not effectively remove suspended dirt in water, and is difficult to satisfy increasingly strict water quality standard requirements. Meanwhile, the back flushing function of the traditional equipment is not perfect, the back flushing flow is complex, dirt trapped in quartz sand cannot be fully flushed, the service life of the quartz sand is affected, and the filtering effect of the equipment is reduced. In addition, the connection mode of each part of the equipment is not flexible enough, which is not beneficial to the installation, maintenance and replacement of the equipment, and increases the use cost and the operation difficulty. Therefore, it is needed to develop a quartz sand filter device with optimized structure, good filtering effect, convenient back flushing and convenient maintenance. Disclosure of utility model Therefore, in order to solve the defect that the back flushing function is not perfect enough and the back flushing flow is complex, the utility model provides quartz sand filtering equipment. The utility model discloses quartz sand filtering equipment which is realized by the way, and is characterized by comprising a filtering cylinder body, quartz sand filled in the inner cavity of the filtering cylinder body, a base, an upper end fixing seat, a water inlet pipe, a water outlet pipe, a sewage outlet and an inner pipe, wherein the water inlet pipe, the water outlet pipe and the sewage outlet are respectively fixed on the upper end fixing seat, the water inlet pipe is provided with a branch pipe communicated with the inner cavity of the filtering cylinder body, the branch pipe is used for feeding water into the filtering cylinder body during back flushing, a first valve is arranged on the branch pipe, the other end of the water inlet pipe is communicated with the inner pipe, a second valve is arranged between the inner pipe and the water inlet pipe, the sewage outlet is communicated with the inner pipe, a third valve is arranged on the sewage outlet, the sewage outlet is used for discharging sewage during back flushing, and water quality is fed below the quartz sand during back flushing. The quartz sand filtering equipment is characterized in that the base is positioned at the bottom of the filtering cylinder body, the base and the filtering cylinder body are in detachable movable connection, the upper end fixing base is positioned at the upper part of the filtering cylinder body, and the base and the filtering cylinder body are in detachable movable connection. The quartz sand filtering equipment is characterized in that the water inlet pipe, the water outlet pipe, the sewage outlet and the inner pipe are respectively stainless steel pipelines.
