Filter tower

Abstract

The invention discloses a filter tower, a filter is arranged in the filter tower, a spray pipe connected with a water inlet pipe is horizontally arranged above the filter, and the lower end of the filter tower is connected with a drain pipe. When the filter tower works, water which needs to be purified can be pumped and sent to the spray pipe of the filter tower through a water pump, sprayed and then filtered by multiple layers of filter screens and multiple non-woven cotton filter layers of the filter, then the clean water returns into a water pond via the drain pipe, and the effect of purifying the water quality can be achieved by repeating the operation multiple times; when the water quality becomes poor, the work is repeated; therefore, the water containing impurities can be purified, the blockage of a small hole in a water cooling roller of a printing machine can be avoided, the maintenance workload can be further reduced and the water consumption can be saved.

Description

technical field [0001] The invention relates to a filter tower for purifying water. Background technique [0002] In printing equipment, due to the needs of the process, a cooling water system is needed to cool the equipment. In the cooling water system, the cooling water is often affected by factors such as paper dust, dust, water pipe corrosion, rust, and water impurities. The water will become very dirty, there are a lot of suspended particles in the water, and when such cooling water passes through the pores inside the water cooling roller of the printing press, it is very easy to pile up, thereby blocking the small holes inside the water cooling roller, making The cooling effect becomes worse, and the frequent removal and washing of the water cooling roller, or the replacement of cooling water, will bring great inconvenience to production. Contents of the invention [0003] The present invention overcomes the shortcomings of the prior art and provides a filter tower ...
