Abstract

The utility model relates to a ceramic filter for metallurgical dressing equipment, in particular to an acid resisting rotor which is used for solving the problems that in the prior ceramic filter, the efficiency of the complete machine is influenced by the corrosion of a main shaft of the rotor in the acid cleaning procedure and the ceramic filter has short service life. The acid resisting rotor comprises a main shaft and a cylinder body arranged on the main shaft, wherein a distribution pipe for vacuumizing and introducing acid liquor is arranged in the main shaft; the main shaft and the cylinder body form a detachable connection structure; and an acidproof pipe sleeve is arranged in the distribution pipe. In the utility model, the detachable connection of the main shaft and the cylinder body brings convenience to the overhaul and the replacement of the main shaft; the acidproof pipe sleeve effectively separates a distribution hole of the main shaft from the acid liquor, and ensures the fit of the end surface of the main shaft and a distribution pan, so that the vacuum degree is high, and ore concentrate has high yield and good quality when the acidproof pipe is applied in the filtering process of ore dressing; and with the acid resisting rotor, the service life of the ceramic filter is prolonged to four to five years from less than one year in the prior art.

Description

The acidproof rotor of ceramic filter

Technical field

The utility model relates to the ceramic filter that uses in the technics of metallurgy mineral dressing equipment, refers to a kind of acidproof rotor of ceramic filter particularly.

Background technology

Ceramic filter has a wide range of applications in industries such as metallurgy, chemical industry as a kind of separation equipment of solid-liquid efficiently.Illustrated in figures 1 and 2 in the basic functional principle of existing ceramic filter such as this Figure of description, it mainly comprises by the integrally formed rotor of main shaft 1 and cylindrical shell 2, is fixed on ceramic wafer 5, slurry vessel 7, vacuum barrel 8, belt conveyor 9, Vltrasonic device 10 on the filter support 4 of main shaft 1.During work, motor-driven main shaft 1, and then drive ceramic wafer 5 rotates in slurry vessel 7.It roughly is divided into four courses of work:

(1) the formation stage of filter cake 6 in the region of no pressure 11: the slip in the region of no pressure 11 is adsorbed at its contained solid particle under the effect of vacuum power and forms filter cake 6 on the ceramic wafer 5, and filtrate is through ceramic wafer 5 micropores, the filter chamber 3 final vacuum barrels 8 that arrive;

(2) drying stage of filter cake 6 in the dry section 12: filter cake 6 continues to deviate from filtrate under the effect of vacuum power when dry section 12, and filtrate is through the filter chamber 3 final vacuum barrels 8 that arrive;

(3) the discharging stage of filter cakes 6 in the discharge zone 13: at discharge zone 13, filter cake on the ceramic wafer 56 is scraped by scraper;

(4) wash phase in the backwash district 14: the filtrate water in the vacuum barrel 8 is drawn out of, and a part is got back to backwash district 14 cleaning ceramic plates 5, and another part can efflux utilization; Also can utilize Vltrasonic device 10 and acid solution to carry out physics simultaneously respectively cleans and Chemical cleaning.

Because ceramic wafer 5 absorption slips are to have utilized capillarity, some fine particles, especially metal ion wherein is difficult to only remove the micropore that stops up ceramic wafer 5 by backwash and ultrasonic cleaning, influences the usefulness and the service life of filter.So above-mentioned pickling is very necessary.Acid solution is under the effect of sour pump, and the distributing pipe 15 that is provided with in the main shaft 1 of rotor arrives ceramic wafer 5.Because main shaft 1 is a stainless steel, under long-term acid liquid corrosion, the quality of fit of its section is destroyed gradually, finally causes the filter cisco unity malfunction.Actual operating state shows that the rotor use that is made of main shaft 1 and cylindrical shell 2 just needed to change less than 1 year.

Summary of the invention

The purpose of this utility model is exactly to overcome above-mentioned existing ceramic filter to influence short defective of complete machine usefulness and life-span because of the main shaft of its rotor in the pickling process is corroded, design a kind of acidproof rotor of ceramic filter, its main shaft is acidproof, and can for convenience detach, replacing.

For achieving the above object, the acidproof rotor of the ceramic filter that the utility model is designed, comprise main shaft and the cylindrical shell that is installed on the main shaft, be provided with the distributing pipe that is used to vacuumize and import acid solution in the main shaft, its special character is: described main shaft and cylindrical shell are detachable syndeton, are provided with the acid-proof pipe box in the described distributing pipe.

Advantage of the present utility model is: main shaft adopts detachable the connection with cylindrical shell, is convenient to the maintenance of complete machine and the replacing of main shaft; The setting of acid-proof pipe box effectively isolated the dispensing orifice and the acid solution of main shaft, guaranteed cooperating of its end face and cross gas plate, thereby the vacuum height when being applied to the filtration operation of ore dressing, can make the output height of concentrate, quality good; The ceramic filter life-span of using this acidproof rotor never year and a day brought up to four to five years.
