The scraper device includes a drive shaft and a fixed bracket, the drive shaft is provided with a scraper sleeve, the drive shaft and the scraper sleeve are fastened with nuts, and the scraper sleeve is provided with a scraper; the fixed The lower part of the bracket is provided with a motor sleeve, and a fastening bolt is arranged between the motor sleeve and the fixed bracket. A motor is arranged in the motor sleeve, and a screw and a fastening knob are arranged on the upper part of the fixed bracket. The screw controls the height of the bracket, and the fastening knob and the The flotation machine is tightly connected. The device is simple in structure, easy to operate, convenient to move the position of the scraper sleeve, avoiding the scraper from rubbing against the flotation cell, and effectively improving the accuracy and safety of the experiment.

Description

A kind of scraper device with sleeve flotation machine

technical field

The utility model relates to a scraper device of a flotation machine, in particular to a device suitable for efficient scraping of flotation concentrate by a laboratory flotation machine.

Background technique

At present, commonly used laboratory flotation machines use a suspended scraper mechanism for scraping. This mechanism is suitable for flotation processes with thin foam layers and low coal content. Under installation conditions, the scraper is easy to be knocked down into the flotation tank, contaminating the pulp and affecting the accuracy and safety of the flotation test.

Contents of the invention

In view of the above-mentioned shortcomings, the utility model provides a scraper device which can effectively improve the flotation accuracy and work stably.

In order to achieve the above object, the utility model flotation machine scraper device includes a transmission shaft and a fixed bracket, the transmission shaft is provided with a scraper sleeve, a nut is arranged between the transmission shaft and the scraper sleeve, and the scraper The sleeve is provided with a scraper; the lower part of the fixed bracket is provided with a motor sleeve, and a fastening bolt is provided between the motor sleeve and the fixed bracket; a motor is provided in the motor sleeve; The knob and screw control the height of the bracket, and the fastening knob is closely connected with the flotation machine.

Beneficial effects: In the utility model, the two ends of the drive shaft and the scraper sleeve are connected with nuts, which can flexibly change the position of the sleeve on the drive shaft, or replace the scraper sleeve, so as to adapt to the width and height of the flotation cell. The inconsistency of the width of the scraper ensures the accuracy and safety of the experiment.
