Method and equipment for eliminating iron scraps from raw materials

Abstract

The invention discloses method and equipment for eliminating iron scraps from raw materials. The equipment comprises a rack, a charging bucket and a group of magnetic rods, and is characterized in that rotary arms are arranged on the rack and can horizontally rotate around the rack; a lifting mechanism is arranged on each of the rotary arms; rotary mechanisms are connected to the bottoms of the lifting mechanisms; a group of iron barrels are connected to the lower parts of each of the rotary mechanisms; a connection plate, a vibrator and an iron barrel connected with the connection plate are arranged in the group of iron barrels; the group of iron barrels is driven by the lifting mechanisms to sleeve iron barrels on the magnetic rods in the group of the magnetic rods; a motor, a rotary disc and a spring are arranged in each of the rotary mechanisms; each of the rotary disc is connected with each of the motors; a spring is fixed between each of the connection plates and each of the rotary discs; and vibrators are arranged on the connection plates. The method and the equipment have the beneficial effects that the iron barrels and the magnetic rods rotate in the charging bucket when irons are attracted, so that the contact probability of the iron barrels and slurries is increased, and the iron-attraction effect is improved; and when the iron barrels are subjected to iron removal, another group of iron barrels are quickly sleeved on the magnetic rods to perform the next round of iron attraction, so that the iron removal time is shortened, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the field of magnetic separation for separating solid materials from fluids, in particular to a method and equipment for removing iron filings from raw materials. Background technique [0002] In the fields of chemical industry and ceramics, liquid slurry is often used as raw material to produce solid products. Since the mineral itself contains a certain amount of iron filings, the presence of iron filings in the slurry will cause black spots in the produced floor tiles, which affects the quality of the product. In view of this, manufacturers pay more and more attention to the problem of iron removal, and put forward higher requirements for iron removal equipment. In order to obtain a high-quality iron removal effect, people initially use a manual magnetic bar iron removal process, through the adsorption of iron filings by the magnetic bar, and then manually remove the iron filings on the magnetic bar. This iron removal proce...

Problems solved by technology

[0004] 1. Due to the method of hoisting the magnetic rods, a set of hoisting mechanism is rotated to the top of each slurry drum, first the magnetic rod group is hoisted out of the slurry drum, and then the hoisting mechanism moves horizontally to the top of the iron filings tray, and then The movement of the scraper on the magnetic rod will scrape the iron filings adsorbed on the magnetic rod to the iron filing disc, which will increase the probability of collision and scratching of the magnetic rod, and long-term work will easily lead to the degaussing of the magnetic rod, thereby reducing the efficiency of iron removal. Effect

[0005] 2. Due to the use of multiple slurry cylinders, the hoisting mechanism needs to move to the top of different slurry cylinders, and every time iron removal has to go through: magnetic rod group rises—magnetic rod group moves horizontally—scraper moves down— —The horizontal return of the magnetic rod group——the process of the falling of the magnetic rod group leads to too long time for each iron removal, which reduces the iron removal efficiency

[0006] 3. Since the iron scraper moves along the length direction of the magnetic bar to scrape off the iron filings on the magnetic bar, the frequent movement of the iron scraper along the magnetic bar will easily damage the sealing ring between the iron scraper and the magnetic bar. After the ring is damaged, it needs to be stopped for replacement, which is very cumbersome and affects production

Moreover, the iron scraper structure also has the following defects: since the iron scraper is an iron plate, it will be magnetized after contacting the magnetic bar to generate another magnetic field, and the iron scraper frequently moves along the length of the magnetic bar, which will cause alternating magnetic field problem

However, there has been no ideal iron removal equipment in the prior art, which cannot meet the comprehensive performance requirements of ceramic enterprises for iron removal equipment
