When the frequency of twisting the wedge-shaped end of the telescopic scraper 50 is regular and stable, the expansion amount of the expansion air bag 56 steadily increases to the threshold value, and at this time, it can be determined that the working state of the crushing disc 26 is normal and stable, and when the expansion amount of the expansion air bag 56 increases unstably and late and cannot reach the threshold value, and the wedge-shaped end of the telescopic scraper 50 continues to repeatedly twist irregularly, it can be determined that the crushing disc 26 is severely worn, the crushing and grinding of the iron powder are affected, and replacement treatment is required.
Meanwhile, when the crushing disc 26 is identified to be in a normal working state, the crushing disc 26 crushes and grinds iron powder in the crushing cavity 20, the crushing cavity 20 is lifted and lowered along the fixing column 48, the crushing cavity 20 drives the telescopic scraping plate 50 and the pressing plate 52 to lift, the telescopic scraping plate 50 slides towards the center of the crushing cavity 20 along the inclined plane of the limiting block 51 while being lowered, accordingly, the telescopic scraping plate 50 scrapes the bottom surface of the screen 21, the expansion air bag 56 absorbs heat generated by the crushing disc 26 for grinding and crushing the iron powder, the telescopic scraping plate 50 is tightly attached to the bottom surface of the screen 21, fragments clamped in the screen holes are scraped back to the screen 21 to be continuously crushed and ground by the crushing disc 26, the telescopic scraping plate 50 is lowered, the pressing plate 52 is driven to vertically lowered along the supporting box 54 to press the air bag 53 to charge the inside of the annular pressing air bag 55, the annular pressing air bag 55 blows air to the center part inside the flushing chamber 1, and then the iron powder falling on the center part of the bottom of the flushing chamber 1 is blown out.
When the crushing disc 26 crushes the grinding iron powder, the heat generated by friction enables the expansion air bag 56 to absorb heat and expand, the telescopic scraping plate 50 is enabled to tightly attach the screen 21, the iron powder fragments clamped in the screen holes can be removed, meanwhile, the expansion amount of the expansion air bag 56 is used as a control signal of a fan, when the crushing disc 26 starts to crush the grinding iron powder, the friction force is gradually increased to the maximum, the heat is also increased to the maximum, the expansion amount of the expansion air bag 56 reaches the maximum threshold value after absorbing heat, a control center receives a signal, the fan is controlled to not work in the heat increasing process, at the moment, the amount of the iron powder which falls to the central part of the flushing chamber 1 is small, the annular compression air bag 55 is only pushed to blow the iron powder to the central part of the flushing chamber 1 by pressing the air bag 53, the iron powder can be blown away by the annular compression air bag 55, the auxiliary turning plate 16 can be used for turning the iron powder, the iron powder can be cooled, and the influence on later wetting caused by condensation after rapid cooling of the iron powder is prevented.
Along with the gradual decrease of the ground iron powder, the iron powder quantity which descends to the central part of the flushing chamber 1 gradually increases, the heat generated by friction also gradually decreases, the expansion quantity of the expansion air bag 56 starts to decrease from the maximum threshold value, the control center receives a signal, the control fan starts to gradually pressurize along with the decrease of the expansion quantity, the blowing force of the annular pressurizing air bag 55 increases along with the increase, the gradually increased iron powder accumulated at the central part of the flushing chamber 1 is blown away to the lower part of the turning plate 16, the turning plate 16 is assisted to comprehensively turn and dissipate the heat of the iron powder, and the iron powder is prevented from being accumulated at the central part of the flushing chamber 1 in a concentrated manner, so that the subsequent flushing effect is affected.
When the iron powder in the crushing cavity 20 is ground and crushed and falls into the flushing chamber 1, heat generated by friction disappears, the expansion amount of the expansion air bag 56 is zero, a control center receives a signal, the control fan is pressurized to the maximum and keeps stable, the blowing force of the annular pressurizing air bag 55 is increased to the maximum and keeps stable, at the moment, the water pump 9 starts pumping water from the water tank 10 and sprays water to flush the iron powder through the spray head 13, the stirring plate 16 continuously stirs the iron powder in the flushing chamber 1 to uniformly spray and moisten the iron powder, and meanwhile, the annular pressurizing air bag 55 continuously blows the iron powder slurry in the central position below the stirring plate 16, so that the iron powder slurry which is in the central position of the flushing chamber 1 and cannot be stirred by the stirring plate 16 can be stirred sufficiently, and the iron powder cannot be stirred in time by the stirring plate 16 after being sprayed with water, so that the agglomeration is prevented, and the flotation effect of the subsequent flotation tank 2 is affected.
Further, the expansion blade 50 cleans the screen 21 and the expansion air bag 56 blows off the iron powder accumulated in the center of the flushing chamber 1, and it is possible to detect whether or not the operating state of the crushing disc 26 is stable by the mutual cooperation between the angle change of the wedge-shaped end in the expansion blade 50 and the expansion amount change of the expansion air bag 56.
The horizontal distance of the inclined surface of the wedge-shaped end of the telescopic scraper 50 is smaller than the mesh size of the screen 21, and the cleaning of fragments is not affected when the wedge-shaped ends of the two telescopic scraper 50 move to the center position of the screen 21 at the same time.
The separation flotation device is internally connected with a control center, and the control center can control electronic components in the device.

s4, after the wetted iron powder falls into the flotation box, starting an air pump, filling air into the flotation box through an air outlet pipe, enabling a fourth bevel gear and a first bevel gear to rotate under the rotation of a chain wheel, enabling a stirring shaft to rotate by the first bevel gear, enabling blades to stir the iron powder, performing flotation work, and finally opening a valve of a discharging pipe to discharge the iron powder after flotation.
