Description

Technical Field

[0001] The invention relates to the technical field of mineral processing, in particular to a quartz sand grinding device with adjustable coarseness and fineness. Background Art

[0002] Quartz sand grinding equipment is a mechanical equipment used to process quartz stone into quartz sand or further grind quartz sand to meet specific particle size requirements. Common quartz sand grinding equipment includes ball mills. Its working principle is that during the rotation of the cylinder, the internal steel balls continuously impact and grind the materials to grind the quartz stone into quartz sand. The quartz sand can be ground into a specific particle size by adjusting the number of steel balls in the ball mill and the rotation speed of the ball mill. In the process of grinding quartz stone into quartz sand, the particle size of quartz sand is controlled by adjusting the number of steel balls in the ball mill and the rotation speed. By adjusting the number of steel balls, the impact and grinding frequency of the steel balls on the quartz sand can be changed. More steel balls mean a higher grinding frequency, which helps to grind the quartz sand finer. On the contrary, the grinding effect is relatively weakened when the number of steel balls is reduced, which is suitable for coarse grinding or preventing over-grinding.

[0003] When adjusting the number of steel balls in the ball mill, the ball mill needs to be disassembled from the bracket first, and then the steel balls need to be taken out from the inside of the ball mill using tools such as grabs. This process has many inconveniences. The operation of disassembling the ball mill from the bracket and taking out the steel balls requires the participation of multiple professionals, and the use of large lifting equipment during the operation is extremely time-consuming. After the ball mill is reinstalled, debugging and calibration work is required, which greatly reduces the overall work efficiency. Summary of the invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1 Reference Figure 1 to Figure 11 , which is the first embodiment of the present invention, and this embodiment provides a quartz sand grinding device with adjustable coarseness and fineness. The quartz sand grinding device with adjustable coarseness and fineness includes a grinding component 200, an adjustment component 300 and a main component 100. The three can cooperate to adjust the number of steel balls for grinding quartz sand in the ball mill.

[0033] The grinding assembly 200 includes a grinding piece 201, including a rotating wheel 201a, a storage frame 201b, a baffle 201c, a worm wheel 201d and a worm 201e. The storage frame 201b is sleeved on the outside of the rotating wheel 201a, the storage frame 201b and the rotating wheel 201a are rotatably connected through a rotating shaft, the baffle 201c is fixed to the inner wall of the storage frame 201b, the worm wheel 201d is fixed to one end of the rotating wheel 201a, and the worm 201e is arranged at the bottom of the worm wheel 201d, and the worm 201e and the worm wheel 201d are meshed.

[0034] A leakage groove of the same size as the steel ball is opened on the rotating wheel 201a, and a solid block 202a is arranged in the leakage groove on one side. When the grinding machine 101 stops rotating, the steel ball will move to the top of the grinding machine 101, above the storage frame 201b, and then the user rotates the worm 201e, the rotation of the worm 201e will drive the worm wheel 201d to rotate, and the worm wheel 201d drives the rotating wheel 201a to rotate, so that the empty leakage groove faces upward, and some steel balls will fall into the leakage groove at this time and be wrapped by the leakage groove, and then the rotating wheel 201a continues to rotate, and the rotation of the rotating wheel 201a can move the steel balls in the leakage groove to the storage frame 201b, so that they fall into the storage frame 201b, and are arranged in the storage frame 201b through the baffle 201c. The arrangement can form multiple chambers in the storage frame 201b for storing steel balls. When the grinder 101 rotates, the steel balls are prevented from shaking in the storage frame 201b. Three to five steel balls can be placed in one chamber. After the number of steel balls is reduced, the leakage groove with one side of the solid block 202a is facing upward. When the steel balls in the storage frame 201b need to be taken out, the grinder 101 is rotated to make the storage frame 201b rotate to be tilted, and then the rotating wheel 201a is rotated, so that the steel balls in the storage frame 201b can fall into the leakage groove on the rotating wheel 201a by gravity, and then the rotating wheel 201a can make the steel balls fall back into the grinder 101 by rotating, so as to adjust the number of steel balls in the grinder 101.

[0035] The adjustment component 300 is arranged on the grinding component 200, and includes an adjustment member 301, including an extrusion bar 301a, a movable column 301b, an extrusion block 301c, a gear rod 301d, a moving block 301e and a stop block 301f. The extrusion bar 301a is arranged on the grinding component 200, the movable column 301b is located above the extrusion bar 301a, the extrusion block 301c is arranged on the top of the movable column 301b, the gear rod 301d is located on the top of the extrusion block 301c, the moving block 301e and the gear rod 301d are on top, and the stop block 301f is arranged on one side of the moving block 301e.

[0036] When the rotating wheel 201a is rotating, the user may forget how many times the rotating wheel 201a has rotated due to interference from some external factors. In this case, the number of rotations can be limited by setting the adjusting member 301, so that the number of rotations of the rotating wheel 201a can be controlled, thereby controlling the number of steel balls in the grinding machine 101. There are three stoppers 301f, all of which are set on one side of the moving block 301e. The three are arranged in order at a specified interval. When the number of rotations of the rotating wheel 201a needs to be limited, one of the stoppers can be adjusted. 301f is moved, and after the stopper 301f is moved to the specified position, the extrusion bar 301a is rotated by rotating the worm 201e. When the extrusion bar 301a rotates to contact the bottom of the movable column 301b, the movable column 301b is squeezed to move it. The movement of the movable column 301b drives the extrusion block 301c to move. The extrusion block 301c is set as an inclined surface. The bottom of the gear rod 301d is provided with an inclined tooth groove corresponding to the extrusion block 301c. When the extrusion block 301c moves, it squeezes the inclined tooth groove As a result, the gear rod 301d moves, and the movement of the gear rod 301d drives the moving block 301e to move. When the moving block 301e moves to the side of the stopper 301f, the moving block 301e is limited by the setting of the stopper 301f, thereby preventing the gear rod 301d from continuing to move. At this time, when the extrusion bar 301a squeezes the movable column 301b to drive the extrusion block 301c to move, the extrusion block 301c will no longer squeeze the gear rod 301d to make it move, thereby preventing the worm 201e from continuing to rotate. The distance of the stopper 301f will be set in advance. Each time the limit is set, the leakage groove with one side of the solid block 202a will be facing upward. By adjusting the number of steel balls in the ball mill 101, the grinding degree of the quartz sand can be accurately controlled. When finer-grained quartz sand is needed, the number of steel balls can be increased to make the collision and grinding between the steel balls and the quartz sand more complete, thereby obtaining a product with a smaller particle size; conversely, when a coarser particle size is needed, the number of steel balls can be reduced. This flexibility helps to meet various specific industrial needs.

[0037] Example 2 Reference Figure 1 to Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, the grinding assembly 200 further includes a support member 202, which is disposed on the storage frame 201b. A solid block 202a is fixed to one side of the rotating wheel 201a, and an inclined panel 202b is fixed to the inner wall of the storage frame 201b.

[0039] There are eight solid blocks 202a, all of which are arranged in the leakage groove on one side of the rotating wheel 201a. When the grinder 101 rotates, the storage frame 201b can be formed into an arc shape by driving one side of the solid block 202a upward, and an arc panel corresponding to the arc storage frame 201b is also arranged in the grinder 101. When the quartz sand is rotated to grind, the arc panel and the arc storage frame 201b can guide the steel balls, so that the grinding effect of the quartz sand in the grinder 101 will be more uniform. The setting of the inclined panel 202b can guide the steel balls in the chamber of the storage frame 201b, so that the steel balls can move to one side of the chamber to facilitate the entry of the next steel ball.

[0040] Specifically, a shielding cover 202c is sleeved on the outer side of the worm 201e, the worm 201e is inserted into the storage frame 201b, the worm 201e and the storage frame 201b are rotatably connected via a rotating shaft, and a rotating rod 202d is fixed to one end of the worm 201e.

[0041] The shielding cover 202c is fixed to the inner wall of the grinder 101, and the rotating rod 202d is rotatably connected to the shielding cover 202c via a rotating shaft. The shielding cover 202c can be provided to protect the rotating rod 202d and the worm 201e to prevent the steel ball from hitting the worm 201e and the rotating rod 202d and causing the two to bend during grinding. The rotation of the rotating rod 202d can drive the worm 201e to rotate, and at this time, the rotation of the worm 201e can drive the worm wheel 201d to rotate.

[0042] Specifically, an operating frame 202e is sleeved on the outer side of the rotating rod 202d, and the operating frame 202e is rotatably connected to the rotating rod 202d through a rotating shaft. A rotating disk 202f is fixed to one end of the rotating rod 202d, and the rotating disk 202f is rotatably connected to the operating frame 202e through a bearing.

[0043] The operating frame 202e is fixed to one side of the grinder 101. The operating frame 202e can support the rotating rod 202d to prevent the rotating rod 202d from being offset. A crank is provided on one side of the turntable 202f. The turntable 202f can be rotated by rotating the crank, and the turntable 202f can drive the rotating rod 202d to rotate by rotating.

[0044] Specifically, a first gear 202g is sleeved on the outer side of the rotating rod 202d, a second gear 202h is provided on one side of the first gear 202g, the first gear 202g and the second gear 202h are meshed, the second gear 202h is rotatably connected to the inner wall of the operating frame 202e through a rotating shaft, and the extrusion strip 301a is fixed on one side of the second gear 202h.

[0045] When the rotating rod 202d rotates, it drives the first gear 202g to rotate, and the first gear 202g drives the second gear 202h to rotate. The rotation of the second gear 202h can drive the squeezing bar 301a to rotate, so that the squeezing bar 301a can squeeze the movable column 301b.

[0046] Specifically, the adjustment component 300 also includes a movable part 302, which is arranged on the movable column 301b. A support plate 302a is sleeved on the outer side of the movable column 301b. The support plate 302a and the extrusion bar 301a are movably connected. The movable bar 302b is fixed on the top of the movable column 301b. The extrusion block 301c is fixed to the top of the movable bar 302b. The support plate 302a is fixed to the inner wall of the operating frame 202e. The first spring 302c is fixed to the inner wall of the support plate 302a. The first spring 302c is fixed to one side of the movable column 301b. The movable bar 302b is plugged into the top of the support plate 302a. The movable bar 302b and the support plate 302a are movably connected.

[0047] When the squeezing bar 301a squeezes the movable column 301b to make it move, the movement of the movable column 301b will drive the movable bar 302b to move. The movement of the movable bar 302b can drive the squeezing block 301c to squeeze the bottom of the gear rod 301d, and the movable column 301b can apply a squeezing force to the first spring 302c when it moves. When the squeezing bar 301a is separated from the movable column 301b, the rebound force of the first spring 302c can drive the movable column 301b to return to its original position.

[0048] Example 3 Reference Figure 2~Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0049] Specifically, a limiting rod 302d is fixed on one side of the gear rod 301d, a slider 302e is fixed on one side of the limiting rod 302d, a second spring 302f is fixed on one side of the slider 302e, the second spring 302f is fixed to the inner wall of the operating frame 202e, a limiting block 302g is set on the top of the limiting rod 302d, a torsion spring 302h is fixed on the inner wall of the operating frame 202e, and the torsion spring 302h is fixed to one side of the limiting block 302g.

[0050] The limit rod 302d is provided with an inclined limit groove corresponding to the limit block 302g, the limit block 302g is set as an inclined surface, the limit block 302g is rotatably connected to the inner wall of the operating frame 202e through a rotating shaft, and a sliding groove corresponding to the slider 302e is provided in the operating frame 202e, the slider 302e slides in the sliding groove, and when the gear rod 301d moves, it will drive the limit rod 302d to move. At this time, the inclined limit groove on the limit rod 302d will squeeze the limit block 302g, which will not affect the normal movement of the limit rod 302d, and when the limit rod 302d moves, it can apply a pulling force to the second spring 302f. In order to prevent the rebound force of the second spring 302f from driving the limit rod 302d to return to its original position, The engagement of the limit block 302g with the inclined surface limit groove can limit the limit rod 302d, preventing the rebound force of the second spring 302f from driving the limit rod 302d to return to its original position. When it is necessary to release the limit on the limit rod 302d, the inclined surface of the limit block 302g is separated from the inclined surface limit groove by squeezing one end of the limit block 302g, thereby releasing the limit on the limit rod 302d, and then the rebound force of the second spring 302f can drive the limit rod 302d to return to its original position. When the inclined surface of the limit block 302g is separated from the inclined surface limit groove, a torsional force can be applied to the torsion spring 302h. When the squeezing on one end of the limit block 302g is released, the rotation force of the torsion spring 302h can drive the limit block 302g to return to its original position for the next use.

[0051] Specifically, the adjustment component 300 also includes a pressing member 303, which is arranged on the stop block 301f.

[0052] There are four movable columns 303a, three of which are fixed on the top of the stopper 301f, the fourth movable column 303a is arranged above the limit block 302g, and a movable plate is fixed at the bottom, the number of pressing columns 303b is four, all of which are fixed on the top of the movable column 303a, the number of lower pressing strips 303k is four, all of which are fixed on one side of the movable column 303a, and the movable plate 303c is provided with guide grooves corresponding to the lower pressing strips 303k, and the number of the guide grooves is four, three of which are provided with positioning grooves, which will drive the lower pressing strip 303k to move when the pressing column 303b is pressed, and the lower pressing strip 303 When the pressing bar 303k moves to one side of the positioning groove, the movable plate 303c returns to its original position. At this time, the lower pressing bar 303k will move into the positioning groove, and the pressing column 303b will apply a squeezing force to the third spring 303d when it moves. The movement of the pressing column 303b can drive the stopper 301f to press down to limit the moving block 301e, and then the pressing column 303b can be limited by the engagement of the lower pressing bar 303k with the positioning groove to prevent the rebound force of the third spring 303d from driving the pressing column 303b to return to its original position.

[0053] When it is necessary to release the limit of the pressing column 303b, the fourth pressing column 303b is pressed to make the lower pressing strip 303k fixed on one side thereof squeeze the corresponding guide groove. At this time, the movable plate 303c can be moved, so that the lower pressing strip 303k engaged with the positioning groove is separated from the positioning groove, and then the rebound force of the third spring 303d can drive the corresponding pressing column 303b to return to its original position, so that it releases the limit of the moving block 301e. When the fourth pressing column 303b moves, it will also squeeze one end of the limit block 302g to separate the inclined surface of the limit block 302g from the inclined surface limiting groove, thereby releasing the limit of the limit rod 302d, and then the rebound force of the second spring 302f can drive the limit rod 302d to return to its original position, so that the limit rod 302d drives the gear rod 301d to return to its original position for the next use.

[0054] Specifically, a connecting frame 303e is sleeved on the outer side of the movable plate 303c, a first movable bar 303f is fixed to one side of the movable plate 303c, a second movable bar 303g is fixed to the inner wall of the connecting frame 303e, the second movable bar 303g is movably connected to the movable plate 303c, a fourth spring 303h is fixed to one side of the second movable bar 303g, and the fourth spring 303h is fixed to one side of the first movable bar 303f.

The setting of the connecting frame 303e can support the pressing column 303b and the movable plate 303c to prevent the two from deviating. When the movable plate 303c moves, it can drive the first movable bar 303f to move. The movement of the first movable bar 303f will apply a pulling force to the fourth spring 303h. When the limit on the movable plate 303c is released, the rebound force of the fourth spring 303h can drive the movable plate 303c to return to its original position. The second movable bar 303g is used to support the fourth spring 303h to prevent the fourth spring 303h from deviating.

[0056] Specifically, it also includes a main body component 100, which is arranged on the storage frame 201b, including a grinder 101 and a support frame 102. The grinder 101 is sleeved on the outside of the storage frame 201b, and the support frame 102 is arranged at the bottom of the grinder 101.

[0057] By adding steel balls into the grinder 101 and then rotating the cylinder of the grinder 101, during the rotation of the cylinder, the internal steel balls continuously impact and grind the materials to grind the quartz stone into quartz sand. The quartz sand can be ground into a specific particle size by adjusting the number of steel balls in the ball mill and the rotation speed of the ball mill. Quartz stone can be added through the feed port at one end of the grinder 101. A large gear ring is sleeved on the outside of the grinder 101. The motor is connected to the drive wheel to mesh with the large gear ring, so that the grinder 101 can be rotated. The grinder 101 belongs to the prior art and will not be elaborated here. By installing the grinder 101 on the support frame 102, the support frame 102 can be used to support the grinder 101 to prevent the grinder 101 from shifting during use. When other objects need to be polished, the grinder 101 also has a certain applicability. At this time, steel balls of different specifications can be replaced according to actual usage requirements.

[0058] When in use, first add steel balls and quartz stones through the feed port of the grinder 101, then rotate the grinder 101, the steel balls inside continuously impact and grind the materials, grind the quartz stones into quartz sand, and finally discharge them from the discharge port. After the ground quartz sand is discharged, if it is necessary to adjust the number of steel balls in the grinder 101, first limit the number of rotations of the rotating wheel 201a to adjust the number of steel balls to the ideal number, and press the pressing column 303b to drive the lower pressing bar 303k to move. When the pressing column 303b moves, it will apply an extrusion force to the third spring 303d. When the pressing column 303b is pressed, it will drive the lower pressing bar 303k to move, and the lower pressing bar 303k moves to the guide groove. The squeezing can make the movable plate 303c move. When the movable plate 303c moves, it can drive the first movable bar 303f to move. The movement of the first movable bar 303f will apply a pulling force to the fourth spring 303h. When the lower pressing bar 303k moves to one side of the positioning groove, the rebound force of the fourth spring 303h drives the movable plate 303c to return to its original position. At this time, the lower pressing bar 303k will move into the positioning groove, and then the pressing column 303b can be limited by the engagement of the lower pressing bar 303k and the positioning groove to prevent the rebound force of the third spring 303d from driving the pressing column 303b to return to its original position. The movement of the pressing column 303b can drive the stopper 301f to press down to limit the movable block 301e.

[0059] At this time, the crank can be rotated to drive the turntable 202f to rotate, and the turntable 202f can drive the rotating rod 202d to rotate. The rotation of the rotating rod 202d will drive the worm 201e to rotate. At this time, the rotation of the worm 201e can drive the worm wheel 201d to rotate, and the worm wheel 201d drives the rotating wheel 201a to rotate, so that the empty leakage groove faces upward. At this time, some steel balls will fall into the leakage groove and be wrapped by the leakage groove, and then continue to rotate the rotating wheel 201a. Through the rotation of the rotating wheel 201a, the steel balls in the leakage groove can be moved to the storage frame 201b, and thus fall into the storage frame 201b. In the storage frame 201b, the setting of the baffle 201c can form multiple chambers in the storage frame 201b for storing steel balls, thereby reducing the amount of quartz sand ground in the grinder 101.

[0060] When the rotating rod 202d rotates, the first gear 202g is driven to rotate, and the first gear 202g is driven to rotate the second gear 202h. The rotation of the second gear 202h can drive the extrusion bar 301a to rotate, so that the extrusion bar 301a can squeeze the movable column 301b to make it move, and the movement of the movable column 301b drives the extrusion block 301c to move. The extrusion block 301c is set as an inclined surface, and an inclined tooth groove corresponding to the extrusion block 301c is provided at the bottom of the gear rod 301d. When the extrusion block 301c moves, the inclined tooth groove is squeezed to move the gear rod 301d, and the movement of the gear rod 301d drives the moving block 301e to move, and the movement of the gear rod 301d drives the limiting rod 302d to move. At this time, the inclined limiting groove on the limiting rod 302d will squeeze the limiting block 302g, which will not affect the normal movement of the limiting rod 302d. When the second spring 302f rebounds and the limit rod 302d is driven to slide in the sliding groove, the second spring 302f can apply a pulling force to the second spring 302f. In order to prevent the limit rod 302d from returning to its original position due to the rebound force of the second spring 302f, the limit rod 302d can be limited by the engagement of the limit block 302g with the inclined limit groove to prevent the limit rod 302d from returning to its original position due to the rebound force of the second spring 302f. When the moving block 301e moves to one side of the stop block 301f, the moving block 301e is limited by the setting of the stop block 301f, thereby preventing the toothed rod 301d from continuing to move. At this time, when the extrusion bar 301a squeezes the movable column 301b to drive the extrusion block 301c to move, the extrusion block 301c will no longer squeeze the toothed rod 301d to make it move, thereby preventing the worm 201e from continuing to rotate, thereby controlling the number of rotations of the rotating wheel 201a.

[0061] When it is necessary to release the limit of the pressing column 303b, the fourth pressing column 303b is pressed to make the lower pressing strip 303k fixed on one side thereof squeeze the corresponding guide groove. At this time, the movable plate 303c can be moved, so that the lower pressing strip 303k engaged with the positioning groove is separated from the positioning groove, and then the rebound force of the third spring 303d can drive the corresponding pressing column 303b to return to its original position, so that it releases the limit of the moving block 301e. When the fourth pressing column 303b moves, it will also squeeze one end of the limit block 302g to separate the inclined surface of the limit block 302g from the inclined surface limiting groove, thereby releasing the limit of the limit rod 302d, and then the rebound force of the second spring 302f can drive the limit rod 302d to return to its original position, so that the limit rod 302d drives the gear rod 301d to return to its original position for the next use.
