On one hand, the ferric oxide impurities can cause yellowing of the quartz sand filter material and reduce the appearance quality, so as to influence the market competitiveness of filter material products, on the other hand, in the filtering process, the ferric oxide impurities are easy to chemically react with other ions in water to generate soluble ferric salt or insoluble ferric oxide precipitates, which not only can adhere to the surface of the filter material to block pores and reduce the filtering flux and the adsorption capacity of the filter material, but also can cause the yellowing phenomenon of the filtered water body to influence the water quality sensory index, and even cause potential risks to human health if the filter material is used for drinking water treatment, and in addition, the existence of the ferric oxide impurities can reduce the chemical stability of the quartz sand filter material, so that the loss of the filter material can be accelerated, the service life of the filter material can be shortened, and the operation and maintenance cost of a filtering system can be increased when the filter material is contacted with corrosive water for a long time.

In order to solve the problems that the separation of quartz sand and scrap iron is incomplete in the magnetic separation process and the scrap iron is wrapped by the quartz sand or the quartz sand is mixed in the scrap iron, the pushing mechanism 9 provided by the invention realizes the full turning and separation of materials through the synergistic effect of the fixed pushing plate 92 and the movable pushing plate 93.

When the rotary drum 6 rotates, the movable push plate 93 rotates in a specific area, so that the inclination angle of the movable push plate 93 turns by 90 degrees to generate a reverse inclination effect, quartz sand on the rotary drum 6 is stirred in multiple directions and multiple angles through the structural design of dislocation arrangement and reverse inclination, so that scrap iron in the quartz sand is exposed, the fixed push plate 92 can scrape the scrap iron adsorbed on the shield 74, the scrap iron adsorbed on the shield 74 is pushed to move downwards by the dislocation arrangement and the structural design of reverse inclination, one fixed push plate 92 pushes upwards, the scrap iron is in the downward movement process in general, quartz sand mixed in the scrap iron falls off under the stirring of the fixed push plate 92, and the effect of the fixed push plate 92 on the general downward pushing of the scrap iron is convenient for separating the scrap iron from the shield 74.
In order to improve the scrap iron separating effect and facilitate quartz sand discharging, the inner scraping plate 82 and the outer scraping plate 86 on the fixed table 8 respectively scrape the scrap iron and the quartz sand which are fully separated on the shield 74 and the rotary drum 6, the scrap iron is pushed by the fixed pushing plate 92 to be sent to an operation interval of the inner scraping plate 82, the scrap iron is further separated from a magnetic field through the inner scraping plate 82, the scrap iron falls into the discharging table 521 on the inner side of the base 52, the quartz sand moves upwards after hitting the inclined outer scraping plate 86 when slowly falling along with the rotary drum 6, the quartz sand is prevented from being gathered on the rotary drum 6, then the quartz sand enters the discharging groove 53 on the outer side of the upper shell 51, and the thoroughly and efficiency of magnetic separation are further improved through the stirring effect of the rotating materials by the pushing mechanism 9.

In order to solve the problem that the rotation range and rotation time of a movable push plate 93 are uncontrollable, the movable push plate 93 is matched with a deflector rod 96 through an arc plate 65, so that the movable push plate 93 generates compound motion to enhance the separation effect, and the working principle is that the deflector rod 96 on a stand column 91 and the movable push plate 93 are respectively meshed with a rack 95 in an inner cavity of the stand column 91 through a gear IV 97 and a gear III 94, the deflector rod 96 is also connected with the stand column 91 through a torsion spring 98, the deflector rod 96 is periodically pushed to swing when the arc plate 65 on the inner side of the rotary drum 6 rotates along with the rotary drum 6, the deflector rod 96 swings to drive the gear IV 97 to rotate, the gear IV 94 is synchronously rotated through the meshing transmission of the rack 95, and then the movable push plate 93 is driven to rotate through the meshing transmission of the rack 95, and after the arc plate 65 is separated from the deflector rod 96, the deflector rod 96 is reset through the elastic force of the torsion spring 98, the deflector rod 96 is reversely rotated through the gear IV 97 in the resetting process, and the gear IV 94 and the movable push plate 93 reversely swings.
Through this process, the movable push plate 93 can produce periodic swing under the synergistic effect of the deflector rod 96, the rack and pinion 95 and the torsion spring 98, thereby producing an angle overturning effect, so that quartz sand on the rotary drum 6 is generally pushed upwards by the movable push plate 93 under the guidance of the movable push plate 93, a specific position can be pushed downwards, and the stirring force and angle change of materials between the rotary drum 6 and the shield 74 are further enhanced by matching with the dislocation arrangement and reverse inclination structure of the fixed push plate 92, so that the quartz sand and the scrap iron are separated more thoroughly.
Referring to fig. 3 and fig. 6, the radius of the upper part of the inner wall of the drum 6 is larger than the radius of the lower part of the inner wall, an inverted conical cavity is formed, a plurality of decelerating rings 63 are arranged on the inner wall of the drum 6, the decelerating rings 63 slightly bulge on the inner wall of the drum 6, the movable push plate 93 and the decelerating rings 63 are arranged in a staggered manner, a discharge hole 64 is arranged on the drum 6, an outer scraper 86 is arranged at the discharge groove 53, and when the discharge hole 64 rotates to the discharge groove 53, materials blocked by the outer scraper 86 are thrown into the discharge groove 53 through the discharge hole 64.
