Description

Technical Field

[0001] The patent of this invention relates to a pressure-type integrated high-efficiency turbid water purification device in the sewage treatment industry. Background Art

[0002] During the rolling process, turbid circulating water comes into direct contact with the cooling material, carrying with it large amounts of iron oxide scale particles, metal dust, and lubricating grease, creating an oily, turbid circulating water system. This system is characterized by high iron oxide scale concentrations, large particle size, and high oil content. A turbid circulating water treatment system is used to filter and treat this turbid circulating water, thereby meeting the water quality requirements of steel mill production lines.

[0003] In recent years, a number of high-efficiency, integrated, pressure-type turbid water purification systems have emerged. These devices feature a closed, pressure-bearing shell containing three interconnected functional zones: a coagulation zone, an inclined tube sedimentation zone, and a filtration zone. These zones are interconnected from bottom to top. Due to the high concentration of impurities such as iron oxide particles and metal dust, the filter screens used for initial filtration require frequent replacement. This necessitates disassembly of the inclined tube sedimentation and filtration zones above the entire system, a labor-intensive and time-consuming process. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a quick-detachable annular filter screen, which can be completed on the annular cross-section by hand.

[0005] To achieve the above-mentioned object, the quick-detachable annular filter of the present invention comprises an outer ring rail, an inner ring rail, and a plurality of fan-shaped quick-detachable units disposed between the outer ring rail and the inner ring rail, wherein the plurality of quick-detachable units can be combined into a complete annular shape; wherein the quick-detachable units comprise:

[0006] A fan-shaped movable frame, wherein two or more rollers adapted to the ring rail are provided on the outer sides of the inner and outer arcuate side walls of the movable frame;

[0007] Universal wheels are provided on the inner and outer arcuate side walls of the movable frame below the rollers, corresponding to the ring rails;

[0008] Silicone pads are provided on the outer sides of the inner arc-shaped side walls and the outer arc-shaped side walls of the movable frame below the universal wheel.

[0009] Furthermore, the cross-section of the silicone pad is L-shaped.

[0010] Furthermore, a C-shaped groove is provided at the upper end of the inner arc-shaped side wall, and the opening of the C-shaped groove faces the side of the outer arc-shaped side wall; it also includes a clamping and fixing plate adapted to the opening of the movable frame; one end of the clamping and fixing plate is embedded in the C-shaped groove, and the other end of the clamping and fixing plate is fixed to the outer arc-shaped side wall through a bolt-matching mounting hole; the middle part of the clamping and fixing plate is hollow; a filter screen is sandwiched between the clamping and fixing plate and the movable frame.

[0011] The present invention is provided with multiple fan-shaped quick-release units, which are arranged in a ring shape; the combination is convenient and fast; a quick filter screen installation structure is provided on the quick-release unit, making it convenient to use.
