[0001] The invention relates to the technical field of quartz sand, in particular to a drying machine for making machine-made sand from quartz sandstone. Background Art

[0002] As a high-quality building material, quartz sandstone machine-made sand plays an irreplaceable key role in many fields such as modern construction, roads and bridges, and water conservancy projects. In the construction industry, it is widely used in the preparation of concrete and is an important component to ensure the strength, durability and working performance of concrete. With the acceleration of urbanization and the continuous expansion of infrastructure construction, the demand for high-quality building materials has shown a rapid growth trend. According to relevant industry data statistics, in the past five years, in the domestic construction market alone, the annual demand for quartz sandstone machine-made sand has increased at a rate of more than 15%, and it is expected to maintain a high growth rate in the next few years. This continued growth in demand has put forward more stringent requirements on the production efficiency and quality of quartz sandstone machine-made sand.

[0003] However, the existing quartz sandstone machine-made sand dryer is not convenient for stirring the quartz sand during use, which makes it difficult to make the quartz sand roll in all directions and fully in the barrel, resulting in extremely uneven heating of the quartz sand in the drying barrel.

[0014] The present invention has the following beneficial effects: 1. The present invention is provided with a stirring mechanism. At this time, as the rotating shaft 1 rotates, the gear 1 will also rotate accordingly. At this time, the gear 2 on the mixing barrel will rotate along with the rotation of the gear 1. At this time, the rotating gear 2 will drive the mixing barrel to rotate accordingly. As a result, when the mixing barrel rotates, the spiral blade 2 inside it will rotate in the opposite direction to the spiral blade 1. At this time, as the mixing barrel rotates, the rotating shaft and the roller on the lower curved plate will drive the rotating shaft and the roller to rotate accordingly. At this time, the rotating shaft and the roller will support the mixing barrel. Through the rotation of the mixing barrel, the mixing barrel will turn the quartz sand through the spiral blade 2 inside it. At this time, the rotation of the rotating shaft 1 will also drive the connecting rod and the spiral blade 1 on the outer wall to rotate simultaneously. At this time, the quartz sand in the mixing barrel will be stirred by the spiral blade 1, so that the heating is more uniform, thereby achieving the stirring of the quartz sand, so that the quartz sand is evenly heated in the mixing barrel, avoiding the problem of local overheating causing quality damage of the quartz sand, such as particle breakage, performance change, etc., or local overcooling causing moisture residue, thereby ensuring the uniform drying quality of the entire batch of quartz sand.

[0015] 2. The present invention sets a screening mechanism to put the cleaned quartz sand into the material box, and then starts the motor. When the motor rotates, the rotating shaft 1 will also rotate. At the same time, the rotating shaft 1 will drive the belt through the pulley on the rotating shaft 2 to rotate the pulley. At this time, the rotating shaft 2 will also rotate. With the rotation of the rotating shaft 2, the bevel gear 1 will also rotate. The rotation of the bevel gear 1 will drive the bevel gear 2 on the rotating shaft 3 to rotate. At this time, the rotating shaft 3 will also rotate on the fixed plate 2 with the rotation of the bevel gear 2. With the rotation of the rotating shaft 3, the turntable will also rotate. At this time, the rotating shaft 4 on the turntable will change its position according to the rotation. When the rotating shaft 4 changes its position, the hinged rod on it It will rotate on shaft four, and then when shaft four rotates to the lower side, it will push the hinge rod to the back, and the hinge block will be pushed at the same time. When the pulley is pushed, the screening plate will move with it, and the screening plate will slide back and forth on the feed box, thereby screening the quartz sand in the feed box, separating the quartz sand that was originally stuck together and making the quartz sand granular, thereby achieving the effect of screening the quartz sand, allowing the hot air to contact the quartz sand particles in all directions, greatly increasing the heating area, so that the heat can be transferred to each particle more quickly and evenly, thereby accelerating the evaporation rate of water and improving the drying efficiency and quality.

[0016] 3. The present invention provides a heating mechanism, and the sieved quartz sand will fall into the blanking plate, and then the hot air blower is started. After the hot air blower is started, hot air will be blown out. When the hot air contacts the heating wire on the fixed ring, it will further heat it, so that the hot air will reach the temperature for drying the quartz sand, and then the quartz sand in the blanking plate will fall into the feeding pipe through the blanking port above it. The hot air blown by the hot air blower will blow the quartz sand into the mixing barrel. At this time, the quartz sand blown therein will be heated for the first time, and the quartz sand blown by the hot air will be separated again to become independent particles. At this time, the hot air blown by the hot air blower will reach the mixing barrel, so that when the quartz sand enters the mixing barrel from the blanking plate through the feeding pipe, the hot air blowing causes the quartz sand to be heated once before entering the mixing barrel, and is blown into independent particles, greatly increasing the contact area between the quartz sand and the hot air.

[0025] When in use, the cleaned quartz sand is put into the material box 315, and then the motor 2112 is started. When the motor 2112 rotates, the shaft 1 216 will also rotate accordingly.
