Water washing type automatic cleaning filter

Abstract

The invention provides a water washing type automatic cleaning filter. A filter screen cylinder is arranged in an external cylinder, two ends of the external cylinder are sealed through flanges, the middle of the filter screen cylinder is provided with a pollution discharge shaft tube, a plurality of pollution suction tubes with cleaning brushes are distributed in the periphery of the pollution discharge shaft tube, the inner end of the pollution discharge shaft tube is provided with a driving impeller, one side of the external cylinder is provided with a driving water inlet tube for jetting water to the driving impeller, the other side of the external cylinder is provided with a driving water outlet tube, a circulation water inlet tube at the side edge of the external cylinder is connected with the inside of the filter screen cylinder, one end of the pollution discharge shaft tube is provided with a pollution discharge tube connected with the driving water outlet tube, and the side edge of the external cylinder is provided with a circulation water outlet tube. The water washing type automatic cleaning filter is mainly used for filtering various waters, realizes the motor power-free filtration, scale removal and pollution discharge through the above structure, and is especially suitable for being used in the field of central air conditioners and relevant industrial production fields.

Description

technical field [0001] The invention relates to a filter for conveying water to pipelines, in particular to a water flushing automatic cleaning filter. Background technique [0002] In the field of industrial production, many enterprises will use water circulation to install and connect pipes, but in the process of use, due to the changes and influences of the use process and external conditions, various dirt such as impurities will be generated in the circulating water. It affects the normal operation of the water cycle, and in serious cases directly leads to the inability of water to be recycled. In the situation of extremely scarce water resources, it will pose a direct harm to the ecological environment. In order to improve the utilization rate of water resources, many enterprises will install filtering devices to filter circulating water, but the filters currently installed and used are generally driven by motors, which is in line with energy saving, environmental prote...

[0002] In the field of industrial production, many enterprises will use water circulation to install and connect pipes, but in the process of use, due to the changes and influences of the use process and external conditions, various dirt such as impurities will be generated in the circulating water. Affect the normal operation of the water cycle, and in serious cases directly lead to the inability to recycle water. In the situation of extremely scarce water resources, it will pose a direct harm to the ecological environment

In order to improve the utilization rate of water resources, many enterprises will install filtering devices to filter circulating water, but the filters currently installed and used are generally driven by motors, which is in line with energy saving, environmental protection and low carbon The development requirements are very incompatible, and at the same time, the control of the production cost of the enterprise will also have an impact
