The patent is provided with a collection box and a threaded column, and the electromagnetic plate layer on the threaded column is used to adsorb the iron impurities in the quartz sand on the conveyor belt to purify the quartz sand. At the same time, when the threaded column rotates, the collection box is driven to move, and the iron impurities on the outside of the threaded column are scraped off by a scraper and introduced into a drawer for collection, which is convenient for the recovery of iron impurities.

[0004] In the above patent, the iron impurities in the quartz sand on the conveyor belt are adsorbed by the electromagnetic plate layer on the threaded column to purify the quartz sand. At the same time, the threaded column drives the collection box to move when it rotates, and the iron impurities on the outside of the threaded column are scraped off by the scraper and introduced into the drawer for collection, which is convenient for the recovery of the iron impurities.

[0014] A production process of a quartz sand drying production line capable of improving the purity of quartz sand, using the above-mentioned quartz sand drying production line capable of improving the purity of quartz sand, comprises the following steps:

[0016] Step 2: The rotating rod rotates clockwise to drive the breaking rod to rotate clockwise. The breaking rod rotates clockwise to contact the wet quartz sand put into the drying box and break up the agglomerated quartz sand. The broken quartz sand falls on the top of the conveyor belt.

[0017] Step 3: After the quartz sand falls on the top of the conveyor belt, the bar magnet on the inner wall of the conveyor belt absorbs the iron impurities mixed in the quartz sand, and the drying equipment operates to dry the wet quartz sand on the top of the conveyor belt;

[0018] Step 4: After the wet quartz sand on the top of the conveyor belt is dried, the conveyor belt continues to move to drive the dried quartz sand on the top of the conveyor belt to move and discharge through the discharge plate.

[0019] The present invention provides a quartz sand drying production line which can improve the purity of quartz sand. It has the following beneficial effects:

[0020] (1) In the present invention, the rotating rod rotates clockwise to drive the breaking rod to rotate clockwise. The breaking rod rotates clockwise to contact the wet quartz sand put into the drying box and break up the agglomerated quartz sand. Breaking up the agglomerated quartz sand helps to increase the surface area of ​​the quartz sand particles, thereby achieving more uniform and efficient drying and avoiding uneven heating or overheating of part of the quartz sand due to agglomeration. After the quartz sand falls on the top of the conveyor belt, the strip magnets on the inner wall of the conveyor belt adsorb the iron impurities mixed in the quartz sand. By breaking up the agglomerated quartz sand, the iron impurities are more easily adsorbed by the strip magnets, thereby improving the effect of removing iron impurities by the quartz sand.

[0021] (2) The invention flattens the wet quartz sand on the top of the conveyor belt by reciprocating the flattening rod. The reciprocating motion of the flattening rod can evenly distribute the quartz sand, thereby avoiding the accumulation of quartz sand, thereby ensuring that the quartz sand particles can fully receive the drying effect of the drying equipment, thereby achieving a higher drying effect. The bending rod is used in conjunction with the flattening rod to flatten the wet quartz sand on the top of the conveyor belt to prevent the flattening rod from directly compacting the wet quartz sand. If the flattening rod is used directly to compact the wet quartz sand, the moisture inside the quartz sand will be further locked, resulting in tighter quartz sand particles. The cooperation of the bending rod can reduce the direct compression of the sand particles, keeping them in a relatively loose state, thereby improving the drying effect of the quartz sand.

[0022] (3) The invention, by rotating the load-bearing plate while contacting and scraping the conveyor belt, the load-bearing plate scrapes the conveyor belt to scrape off the iron impurities adsorbed by the strip magnet, and removes the iron impurities at the bottom of the conveyor belt by scraping, which can prevent the adsorbed iron impurities from entering the quartz sand again, thereby improving the efficiency of quartz sand purification. The vibration of the gear drives the load-bearing rod to vibrate, and the vibration of the load-bearing rod drives the load-bearing plate to resonate together. The vibration of the load-bearing plate enhances the scraping effect of the load-bearing plate, and the vibration can increase the contact pressure between the load-bearing plate and the conveyor belt, thereby enhancing the scraping effect, further ensuring the efficiency of quartz sand purification.

A quartz sand drying production line capable of improving the purity of quartz sand according to claim 1, characterized in that: The T-shaped rod is in contact with the linkage groove, the arc plate is elastic, the arc plate is in contact with the tooth block, the load-bearing plate is in contact with the conveyor belt, and the tooth block is meshed with the gear.

8. A production process of a quartz sand drying production line capable of improving the purity of quartz sand, using the quartz sand drying production line capable of improving the purity of quartz sand as claimed in claim 7, characterized in that: The following steps are involved: Step 1: When the wet quartz sand needs to be dried, the wet quartz sand is put into the drying box through the feeding frame, and the servo motor drives its output end to rotate clockwise, and the clockwise rotation of the servo motor output end drives the rotating rod to rotate clockwise; Step 2: The rotating rod rotates clockwise to drive the breaking rod to rotate clockwise. The breaking rod rotates clockwise to contact the wet quartz sand put into the drying box and break up the agglomerated quartz sand. The broken quartz sand falls on the top of the conveyor belt. Step 3: After the quartz sand falls on the top of the conveyor belt, the bar magnet on the inner wall of the conveyor belt absorbs the iron impurities mixed in the quartz sand, and the drying equipment operates to dry the wet quartz sand on the top of the conveyor belt; Step 4: After the wet quartz sand on the top of the conveyor belt is dried, the conveyor belt continues to move to drive the dried quartz sand on the top of the conveyor belt to move and discharge through the discharge plate.
