Description

Technical Field

[0001] The utility model relates to the technical field of sand making, in particular to a ball mill for sand making. Background Art

[0002] Sand is a building material, called fine aggregate in construction. It is divided into coarse sand, medium sand and fine sand according to different diameters. It is widely used in metallurgy, casting, ceramics, chemical industry and other industries. In the sand making process, ball mills are mostly used to complete the crushing and grinding process of sand and gravel. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a ball mill sand making machine with announcement number: CN213494064U. This utility model crushes and grinds sand and gravel through the collision of grinding balls, but the sand and gravel can only be ground once, and unqualified sand cannot be repeatedly ground, which reduces the practicality of this utility model. At the same time, when the sand is discharged from the grinding space, dust will be generated. There is no dust collection structure, which can easily cause dust to fill the entire working environment, affecting the subsequent operation of the operator.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0019] (1) The utility model adopts a rotating barrel. When the sand-making ball mill is actually used, the operator manually removes the threaded cover counterclockwise, and then puts sand and gravel into the rotating barrel through the threaded through hole. After the addition is completed, the threaded cover is installed clockwise. After that, the control panel is used to operate the driving motor. The output end of the driving motor drives the gear to rotate through the connecting shaft. Since the gear and the outer gear ring are meshed with each other, the rotating gear can drive the outer gear ring to rotate, and the outer gear ring drives the rotating barrel to rotate. The rotating barrel rotates with the installation shaft as the central axis. In this process, the two sets of guide blocks can guide the sand and gravel inside the rotating barrel to move it into the grinding mill. The gap between the grinding roller and the two sets of guide blocks is used to crush and grind the sand and gravel through multiple sets of grinding heads. The sand that meets the size can enter the two sets of collecting boxes through two sets of filter screens, and the sand and gravel that does not meet the size will continue to be guided by the two sets of guide blocks and continue to be crushed and ground. When the sand that meets the size needs to be discharged, the operator pulls out the lower set of sealing covers and can move out the sand that meets the size inside the same set of collecting boxes through a set of discharge ports on the same side. The right-angle frame can ensure that the grinding roller is fixed. The rotating barrel can be used to repeatedly grind the unqualified sand, which improves the practicality of the ball mill for sand making.

[0020] (2) The utility model adopts an air storage box. According to the above operation, when the sand that meets the size inside is discharged through a group of discharge ports at the bottom, a group of sealing covers on the same side are reset, and then the control panel is used to make the drive motor work. The output end of the drive motor rotates the drive shaft through the connecting shaft, two groups of pulleys and a transmission belt. The rotating drive shaft drives the fan blades to rotate. Air and dust particles can enter the interior of the air storage box through the opening. The air can pass through the filter bag and finally be discharged through the air permeable net. The dust particles will be left by the filter bag. When the filter bag needs to be cleaned, the sealing plug is pulled out and the filter bag is taken out for cleaning. When the cleaning is completed, the filter bag and the sealing plug are reset. The dust collection work can be completed without adding electric equipment. The air storage box is provided with a dust collection structure, which can collect dust particles generated by discharging, thereby providing a guarantee for the safe use of the ball mill for sand making.

[0039] In one embodiment, a threaded through hole is formed on the end surface of the rotating barrel 2 , and a threaded cover 17 is disposed inside the threaded through hole.

[0040] Working principle:

[0041] When the ball mill for sand making is actually used, the operator removes the threaded cover 17 by hand counterclockwise, and then puts sand and gravel into the interior of the rotating barrel 2 through the threaded through hole. After the addition is completed, the threaded cover 17 is installed clockwise. After that, the control panel is used to operate the driving motor 16. The output end of the driving motor 16 drives the gear 15 to rotate through the connecting shaft 14. Since the gear 15 and the outer gear ring 12 are meshed with each other, the rotating gear 15 can drive the outer gear ring 12 to rotate, and the outer gear ring 12 drives the rotating barrel 2 to rotate.

Sand that meets the size can pass through the two groups of filter screens 8 and enter the two groups of collecting boxes 9, and sand and gravel that does not meet the size will continue to be guided by the two groups of guide blocks 3 and continue to be crushed and ground. When it is necessary to discharge the sand that meets the size, the operator pulls out the sealing cover 11 below, and can remove the sand that meets the size in the collection box 9 on the same side through the discharge port 10 on the same side. The right-angle frame 5 can ensure that the grinding roller 4 is fixed. Through the rotating barrel 2, unqualified sand can be repeatedly ground, which improves the practicality of the ball mill for sand making. At the same time, according to the above operation, when the sand that meets the size inside is discharged through a group of discharge ports 10 below, a group of sealing covers 11 on the same side are reset, and then the control panel is used to make the drive motor 16 work. The output end of the drive motor 16 rotates the transmission shaft 22 through the connecting shaft 14, two groups of pulleys 25 and the transmission belt 26, and the rotating transmission shaft 22 drives the fan blades 2 3 rotates, air and dust particles can enter the interior of the air storage box 7 through the opening 19, the air can pass through the filter bag 21, and finally be discharged through the air permeable net 24, and the dust particles will be left by the filter bag 21. When the filter bag 21 needs to be cleaned, the sealing plug 18 is pulled out, and the filter bag 21 is taken out for cleaning. When the cleaning is completed, the filter bag 21 and the sealing plug 18 are reset. The dust collection work can be completed without adding electric equipment. The air storage box 7 is provided with a dust collection structure, which can collect dust particles generated by discharging, and provides a guarantee for the use safety of the ball mill for sand making.
