Industrial automatic water filter

Abstract

The invention discloses an industrial automatic water filter. A drain valve (1) is arranged at the bottom of a cylinder body (5), and a water inlet (18) and a water outlet (7) are arranged on the cylinder body (5). The box (9) is set on the cylinder body (5), and the gear motor (13) connected to the PLC is installed on the cylinder cover. The gear motor (13) is connected to the main shaft (11) through the coupling (12), and the fine filter screen (14) Installed on the main shaft (11), the coarse filter screen (16) divides the filter space inside the cylinder into two parts, the coarse filter chamber (20) and the fine filter chamber (21), and the bottom of the coarse filter chamber (20) is provided with The sewage pipe (17), the bottom of the cylinder (5) is provided with a sewage outlet (2), the part of the sewage pipe (17) exposed outside the cylinder (5) is provided with a sewage discharge motor (3), and the sewage discharge motor (3) Connect with the PLC electric control box (9). The invention can complete the process of automatic filtration and automatic sewage discharge, improve the filtration efficiency and prolong the service life.

Description

technical field [0001] The invention relates to an industrial water filter, in particular to an industrial automatic water filter. Background technique [0002] Industrial water filter is a new type of environmental protection and energy-saving processing equipment. Industrial water filter is a precision equipment that uses filter screens to intercept impurities in water, purify water quality and protect other equipment in the system. It can be used in construction, steel, papermaking, coal mines and other industries. of water filtration. After the automatic water filter is connected to the pipe, the water will enter the filter from the inlet, and the filtered water will flow out from the outlet. When the water passes through the filter, it will be intercepted on the filter because the volume is larger than the filter hole. When it reaches a certain amount, there will be a certain pressure difference between the water outlet and the water inlet. Rotate the filter screen fo...

Problems solved by technology

However, this method of backwashing to clean the water filter has great disadvantages. Such forward and reverse washing can easily damage the filter screen and reduce the practical life of the filter screen. At the same time, the operation mode of forward and reverse washing is very inconvenient

Practical existing industrial water filters, although it can remove particles in industrial wastewater, but industrial wastewater is mostly strong acid and strong alkali water, this kind of strong acid and strong alkali water has a corrosive effect on various equipment that enters later, and damages equipment, or pollute the environment after discharge
