A water filter device

Abstract

The invention provides a water filtering apparatus, which comprises a casing, the casing is formed by connection of a cover casing and a base, the top of the cover casing is provided with a water inlet, a water outlet is provided on the upper part of a sidewall of the cover casing, a central boss is provided on the base, a combined magnetic core is arranged on the central boss, the combined magnetic core comprises a top board, a supporting plate, a hollow column, fixed bolts and a plurality of permanent magnets sleeved on the hollow column, and the polarities of adjacent permanent magnets arereverse, the hollow column is placed between the top board and the supporting plate, the fixed bolts are screwed into the central screwed hole of the central boss on the base through a central aperture on the top board, the hollow column and a central aperture on the supporting plate of the combined magnetic core for integrally fixing the combined magnetic core on the base, filter screens placed between an inner end face of the cover casing and the base are provided around the combined magnetic core. According to the invention, a plurality of permanent magnets are employed to form a multipolar magnetic field which has a large adsorption area and strong adsorption capability to the ferromagnetism impurity, and because the area of the filter screen is large, the invention achieves the purpose that the water treatment amount is large and the filtering effect is good.

Description

technical field [0001] The present invention relates to a water filtering device. Background technique [0002] Chinese patent application number is 90210215 utility model patent application specification discloses a kind of mesh type magnetic filter, and it is made up of parts such as cylinder body and oil filtering magnetic core, and its characteristic is the oil filtering magnetic core that is made up of six magnetic columns, each The first magnetic column is formed by stacking several magnetic blocks according to the opposite polarity. With the screw as the center, two magnetic columns are spaced at an angle of 60°, and the two magnetic columns are arranged according to the opposite polarity. The above-mentioned net-type magnetic filter is used for the purification of insulating oil for transformers and the treatment of other high-cleanliness oils. The space for storing impurities is small, the processing capacity is small, and frequent maintenance is required. Chines...

Problems solved by technology

The water tank made of stainless steel or plastic material in the road roller is generally small in volume and has the problem of small water storage. For example, the cavity in the steel frame is used to form the water tank. Although the volume of the water tank increases, due to the water tank wall It will rust, and the falling rust will block the nozzle. In addition, due to the limitation of the construction site conditions of t
