A rail-type permanent magnet flux linkage filter system for cooling liquid treatment in cold rolling

Abstract

The invention discloses a guide rail type permanent magnet chain filtering system for cold-rolling cooling liquid treatment. The guide rail type permanent magnet chain filtering system comprises a magnetic chain mechanism, a pollution cleaning mechanism, a slag recycling mechanism and a motor transmission mechanism, wherein the pollution cleaning mechanism as a key improvement comprises a roller way unit with a space closed-loop structure, sleeve type slag scrapers correspondingly arranged on magnetic sticks in the length direction in a sleeved manner and guide components for connecting the roller way unit with the sleeve type slag scrapers; when the magnetic sticks drive the slag scrapers to do linear motion together along the chain transmission direction, the slag scrapers and the guide components are fixedly connected to do motion and are restrained by a trace of the roller way unit, and therefore, metal dust adsorbed by the magnetic sticks can be scraped off. According to the guide rail type permanent magnet chain filtering system, the phenomenon that a magnetic stick deforms or is damaged due to rigid contact between the pollution cleaning mechanism which moves to an extreme position and the magnetic stick can be effectively avoided; furthermore, the overall size of the system can be greatly reduced, and the running speed and the following efficiency can be obviously improved. The guide rail type permanent magnet chain filtering system can be widely applied to filtering, purifying and magnetic separation of various types of industrial water which contains iron dust and is adhered with dirt.

Description

technical field [0001] The invention belongs to the technical field of magnetic filtering equipment, and more specifically relates to a guide rail type permanent magnet flux linkage filtering system for cold rolling cooling liquid treatment. Background technique [0002] At present, there are two main types of magnetic filter devices: electromagnetic type and permanent magnet type. The principle of the electromagnetic magnetic filter is to electrify the filling of the filter itself, so that the filling becomes magnetic, thereby absorbing impurities such as iron powder in the emulsion, and then the filling is demagnetized (de-energized). Rinse to remove the adsorbed impurities. The permanent magnetic bar filter is a magnetic bar that uses high-performance permanent magnets as the magnetic source. A powerful magnetic field is formed around the chain drive system to form a magnetic grid, which absorbs iron powder and other particles in the liquid, and then uses mechanical deco...

Problems solved by technology

Through years of practical application in the factory, it can be seen that its shortcomings mainly include: 1. The scraping claws are periodically opened and closed, and continuous decontamination cannot be achieved; 2. The scraping claw has a certain width. Since the magnetic rod will move horizontally when scraping slag, the scraping claw arm will swing within a certain angle, forming a bending moment. Scraper claws, magnetic rods, and even the overload damage of the transmission system also limit the linear speed of the magnetic rod chain drive, thereby reducing the filtration efficiency of the coolant; 3. The scraper arm swings at a certain angle with the direction of the magnetic chain movement Finally, elastic elements are needed to reset it, and the reset accuracy is low and the speed is slow, which will also limit the efficiency of scraping and decontamination to a certain extent; 4. The design of the transmission system of the decontamination mechanism is complicated, resulting in high failure rate and difficult maintenance, but The effect of scraping slag has not been guaranteed, and the iron powder adsorbed by the magnetic rod cannot be scraped off quickly and completely; Wastewater treatment capacity is obviously insufficient
