Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing, in particular to a ball mill for manufacturing quartz sand powder. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone. The color of quartz sand is generally milky white or colorless and translucent. Because it is a hard, wear-resistant, and chemically stable silicate mineral, it is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical solvents, metallurgy, construction and chemical industry. After the quartz stone is mined, it needs to be structurally crushed using designated equipment to form quartz sand particles with smaller extrusion quality. The quartz sand particles need to be ground later to eventually convert the large pieces of quartz stone into usable quartz powder.

[0003] The Chinese patent with application number CN202311467130.1 discloses a ball mill for crushing quartz sand raw materials, including a central box, an upper cover is placed on the top of the central box, a combined processing mechanism is arranged inside the central box, an airflow-inducing mechanism is arranged on the top of the upper cover, and the combined processing mechanism includes a built-in sleeve, a first bearing is fixedly installed on the inner surface wall of the built-in sleeve, a first linkage rod is fixedly inserted on the inner surface wall of the inner shaft of the first bearing, an assembly base is fixedly sleeved on the outer surface wall of the first linkage rod, a group of pneumatic pressure rods are fixedly installed on the bottom of the inner wall of the assembly base, and an external plate is fixedly installed on the top and the top of the shaft end of each pneumatic pressure rod. However, in the process of processing quartz stone, this patent cannot ensure that each part of the material can fully contact with the medium, the impact force of the medium on the material is relatively fixed, and long-term use damages the life of the equipment.

[0004] However, the existing ball mills for manufacturing quartz sand powder still have some problems in actual use. Since the force generated when the material collides with the medium is relatively limited, it cannot be ensured that each part of the material can fully contact the medium during the quartz stone processing process. The impact force of the medium on the material is relatively fixed, and long-term use will damage the life of the equipment. When the centrifugal force is large, the impact angle and strength of the medium on the liner will increase, resulting in faster wear of the liner. At the same time, the irregular movement of the medium leads to insufficient and uneven grinding of the material. Summary of the invention

[0005] The object of the present invention is to provide a ball mill for manufacturing quartz sand powder, which is used to solve the problems of poor grinding effect and uneven and insufficient grinding of quartz sand proposed in the above background technology.

[0006] The present invention is realized by the following technical scheme: a ball mill for manufacturing quartz sand powder, comprising:

[0007] A grinding cylinder, which is cylindrical and has a grinding space inside;

[0008] The guide grooves are structured to have a plurality of equally spaced guide grooves disposed inside the grinding cylinder. A horizontally disposed collecting portion connected to the guide grooves is provided inside the grinding cylinder. The guide grooves are arranged in an annular shape.

[0009] A reciprocating screw rod is connected to the inside of the grinding cylinder and is coaxially arranged with the grinding cylinder. A threaded sleeve is connected to the surface of the reciprocating screw rod, and a push-sweeping block is connected to the surface of the threaded sleeve via a connecting rod.

[0010] The baffle plate is distributed in an annular shape and connected to the surface of the grinding cylinder. The thickness of the baffle plate is greater than the thickness of the grinding cylinder. A supporting assembly is constructed at the lower part of the grinding cylinder.

[0011] Preferably, the push-sweep block is located in the collecting portion and fits the collecting portion, and the width of the push-sweep block is greater than the width of the guide groove.

[0012] Preferably, the surface of the grinding cylinder is configured with a sealing cover located at the back of the collecting portion, and the cross-sectional area of ​​the sealing cover is smaller than the cross-sectional area of ​​the collecting portion.

[0013] Preferably, one end of the reciprocating screw rod passes through the outside of the grinding cylinder, and the end passing through the outside of the grinding cylinder is connected to a rotating handle.

[0014] Preferably, the support assembly includes a base plate arranged below the grinding cylinder, both sides of the base plate are connected to bearing seats through support seats, the grinding cylinder is connected between the bearing seats, and the inner side of the base plate is connected to a reinforcing assembly located directly below the grinding cylinder.

[0015] Preferably, the reinforcing assembly includes a reinforcing plate fixed on the inner side of the bottom plate, and the opposite inner sides of the reinforcing plate are provided with sliding grooves, brackets are connected between the sliding grooves, and the upper part of the bracket is connected to an arc-shaped magnet.

[0019] Preferably, the other end of the grinding cylinder is connected to a feeding mechanism, and the feeding mechanism is coaxially arranged with the grinding cylinder.

[0020] Compared with the prior art, the present invention provides a ball mill for manufacturing quartz sand powder, which has the following

[0021] Beneficial effects:

[0022] 1. The present invention cooperates with the guide groove and the collecting part. Since the annular guide groove is opened inside the ball mill, when the grinding cylinder rotates, the medium inside it can move along the guide groove, which can better accumulate and transfer energy. The shape and structure of the guide groove can enable the medium to obtain greater kinetic energy when falling, thereby producing a stronger impact and grinding effect on the material, further improving the grinding effect, thereby increasing the contact frequency between the medium and the material, and the irregular movement is conducive to the full mixing of the medium and the material, improving the uniformity of grinding, and improving the grinding efficiency of the material.

[0023] 2. The present invention cooperates with the magnet, the baffle plate and the medium, and the medium is magnetically connected to the magnet. On the one hand, the magnet can produce a certain magnetic attraction on the medium, so that the medium approaches the inner wall of the grinding cylinder under the action of the magnet adsorption, and the medium grinds the material during the movement toward the magnet. On the other hand, the falling medium is attracted to increase the acceleration of the medium, so that the medium can produce a greater impact force on the quartz sand, thereby improving the crushing effect of the quartz sand. At the same time, the medium close to the magnet and the falling medium are offset, thereby increasing the grinding effect of the medium on the material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] During operation of the existing ball mill, the force generated when the material collides with the medium 15 is relatively limited, that is, the impact force of the medium 15 on the material is relatively fixed, and the material cannot be ground well.

[0035] like Figures 1 to 7 As shown, a ball mill for manufacturing quartz sand powder comprises: a grinding cylinder 1, which is arranged in a cylindrical shape and has a grinding space inside, a guide groove 8, which is constructed with a plurality of guide grooves 8 that are evenly distributed inside the grinding cylinder 1, a horizontally arranged collecting portion 9 that is connected to the guide groove 8 is opened inside the grinding cylinder 1, and the guide groove 8 is arranged in an annular shape, a reciprocating screw rod 7, which is connected to the inside of the grinding cylinder 1 and is coaxially arranged with the grinding cylinder 1, a threaded sleeve 14 is connected to the surface of the reciprocating screw rod 7, and a push-sweep block 17 is connected to the surface of the threaded sleeve 14 through a connecting rod 16, the push-sweep block 17 is located in the collecting portion 9 and fits with the collecting portion 9, and the width of the push-sweep block 17 is greater than the width of the guide groove 8, one end of the reciprocating screw rod 7 passes through the outside of the grinding cylinder 1, and the end that passes through the outside of the grinding cylinder 1 is connected to a rotating handle 18, and the grinding cylinder 1 The other end is connected to a feeding mechanism 4, which provides quartz sand raw materials for the ball mill. The feeding mechanism 4 is coaxially arranged with the grinding cylinder 1, and the material transmission direction is consistent with the axial direction of the grinding cylinder 1. This design can reduce the energy consumption of the material during the transmission process, because the material can directly enter the inside of the grinding cylinder 1 without changing direction, thereby improving the transmission efficiency. The surface of the grinding cylinder 1 is connected to a transmission part 2, and the surface of the bottom plate 3 is connected to a driving mechanism connected to the transmission part 2. Under the action of the driving mechanism, it can provide power for the operation of the equipment, so that the power generated by the driving mechanism after working can be transmitted to the position of the grinding cylinder 1 through the transmission part 2 to drive the grinding cylinder 1 to rotate, so that the quartz sand raw material is crushed and ground through the internal medium 15, thereby improving the continuity of the action and the conduction effect.

[0036] The ball mill for manufacturing quartz sand powder adopts the above structure, so that the ball mill can maintain stability during operation, and the grinding space provides sufficient movement space for the material and the medium 15, ensuring the grinding efficiency. The quartz sand raw material is added to the ball mill through the feeding mechanism 4, and then the driving mechanism can be started, so that the power generated by the driving mechanism after the operation can be transmitted to the position of the grinding cylinder 1 through the transmission part 2 to drive the grinding cylinder 1 to rotate, so that when the grinding cylinder 1 rotates, the medium 15 therein can move along the guide groove 8. When the medium 15 moves in the guide groove 8, it can better accumulate and transfer energy. The shape and structure of the guide groove 8 can enable the medium 15 to obtain greater kinetic energy when falling, thereby generating energy for the material. Stronger impact and grinding action further enhance the grinding effect, thereby increasing the contact frequency between the medium 15 and the material. Irregular movement is conducive to the full mixing of the medium 15 and the material, improving the uniformity of grinding and the grinding efficiency of the material, so that the quartz sand raw material is crushed and ground by the internal medium 15. The guide groove 8 and the collecting part 9 contribute to the uniform distribution of the material during the grinding process, avoiding excessive accumulation or loss of the material in a certain area. The setting of the collecting part 9 makes it easy to collect and discharge the ground material, thereby improving the operating efficiency of the ball mill. The design of the guide groove 8 in an annular setting further enhances the uniform distribution effect of the material, and also contributes to the uniform distribution and movement of the medium 15.

[0037] The rotational motion of the reciprocating screw 7 can drive the threaded sleeve 14 and the connecting rod 16 and the push-sweep block 17 on its surface to reciprocate. The setting of the push-sweep block 17 helps to clean the residual materials and medium 15 in the grinding space, prevents excessive accumulation and clogging of the materials and medium 15, and ensures the continuous and stable operation of the ball mill. The push-sweep block 17 can fit with the collecting part 9, so that the collecting part 9 can provide certain guidance and limitation for the push-sweep block 17. Because the threaded sleeve 14 can move on its surface under the action of the reciprocating screw 7, and the push-sweep block 17 is located in the collecting part 9, it can provide limitation for the movement of the threaded sleeve 14, avoiding the thread The sleeve 14 rotates together with the reciprocating screw 7 instead of moving in a straight line, which improves the stability of the movement of the push-sweeper block 17, and the push-sweeper block 17 can also avoid moving into the guide groove 8 during the horizontal movement, thereby avoiding deviation and interference. The design of the handle 18 allows the operator to intuitively see and control the rotation of the reciprocating screw 7. By rotating the handle 18, the operator can easily adjust the speed and rotation direction of the reciprocating screw 7, thereby achieving precise control of the grinding process, so that the reciprocating screw 7 can operate independently or move with the ball mill, thereby facilitating the diverse mobility of the push-sweeper block 17 and improving flexibility.

[0038] like Figures 1 to 5As shown, the surface of the grinding cylinder 1 is constructed with a cover 5 located at the back of the collecting portion 9, and the cross-sectional area of ​​the cover 5 is smaller than the cross-sectional area of ​​the collecting portion 9. Through this design, the cover 5 is used to close the opening part of the grinding cylinder 1 to prevent material splashing during the grinding process, while the collecting portion 9 is used to collect and export the ground quartz sand powder, usually located at the outlet of the grinding cylinder 1. The design of the cover 5 allows it to be easily removed from the grinding cylinder 1, thereby allowing the operator to easily access the collecting portion 9 and its internal components. The close fit between the cover 5 and the collecting portion 9 helps prevent the material and medium 15 in the grinding process from leaking to the outside of the grinding cylinder 1, thereby facilitating the material in the collecting portion 9 to be discharged from the position of the cover 5.

[0039] like Figures 1 to 7 As shown, the support assembly includes a bottom plate 3 arranged below the grinding cylinder 1, and bearing seats 20 are connected to both sides of the bottom plate 3 through support seats 6. The grinding cylinder 1 is connected between the bearing seats 20. The cross-sectional area of ​​the bottom plate 3 is larger than the cross-sectional area of ​​the grinding cylinder 1. The inner side of the bottom plate 3 is connected to a reinforcing assembly located directly below the grinding cylinder 1. The bottom plate 3 provides a wider supporting surface. This design enhances the stability of the entire equipment, makes the grinding cylinder 1 more stable during operation, and reduces the displacement caused by vibration or impact. Since the grinding cylinder 1 is connected between the bearing seats 20, the grinding cylinder 1 can be driven by an external driving component to operate independently. Under the action of the support assembly, it can provide support for the grinding cylinder 1, and a reasonable layout can improve the stability of the operation of the device, while the reinforcing assembly can increase the activity of the medium 15 inside the grinding cylinder 1.

[0040] By providing the guide groove 8 and the collecting part 9 in coordination, since the annular guide groove 8 is opened inside the ball mill, when the grinding cylinder 1 rotates, the medium 15 therein can move along the guide groove 8, and can better accumulate and transfer energy. The shape and structure of the guide groove 8 can enable the medium 15 to obtain greater kinetic energy when falling, thereby producing a stronger impact and grinding effect on the material, further improving the grinding effect, thereby increasing the contact frequency between the medium 15 and the material, and the irregular movement is conducive to the full mixing of the medium 15 and the material, improving the uniformity of grinding, and improving the grinding efficiency of the material.

[0041] Embodiment 2

[0042] Based on the above embodiment, during the process of quartz stone treatment, it cannot be ensured that each part of the material can fully contact the medium 15. When the centrifugal force is large, the impact angle and force of the medium 15 on the liner will increase, resulting in faster wear of the liner.

[0043] like Figures 1 to 7As shown, the baffle plate 13 is distributed in an annular shape and is connected to the surface of the grinding cylinder 1. The thickness of the baffle plate 13 is greater than that of the grinding cylinder 1. The setting of the baffle plate 13 helps to enhance the structural strength of the grinding cylinder 1 and ensure the safety and stability of the ball mill. The lower part of the grinding cylinder 1 is structured with a support assembly. The reinforcement assembly includes a reinforcement plate 19 fixed to the inner side of the bottom plate 3. The reinforcement plate 19 is fixed to the inner side of the bottom plate 3, which can effectively increase the rigidity and strength of the bottom plate 3. This design enables the bottom plate 3 to better withstand the weight of the grinding cylinder 1 and the components above it, thereby enhancing the structural stability of the entire equipment. Slide grooves 12 are provided on the relative inner sides of the reinforcement plates 19, and brackets 10 are connected between the slide grooves 12. The design of the slide grooves 12 allows the brackets 10 to be flexibly connected between the reinforcement plates 19 while maintaining a certain stability and firmness. The slide grooves 12 are coaxially arranged with the grinding cylinder 1, and the upper part of the bracket 10 is connected with an arc-shaped arrangement The magnet 11 has a cross-sectional area that is consistent with the cross-sectional area of ​​the baffle plate 13. The arc-shaped magnet 11 can generate a certain magnetic force. A plurality of irregularly distributed media 15 are arranged inside the grinding cylinder 1. The media 15 are all magnetically connected with the magnet 11, which helps to adsorb and fix some magnetic substances. When the baffle plate 13 coincides with the magnet 11, the thickness of the baffle plate 13 can effectively isolate the magnetic force of the magnet 11, thereby preventing the adsorption of the magnet 11 and the media 15. At this time, the media 15 rotates normally in the grinding cylinder 1. When the baffle plate 13 does not coincide with the magnet 11, the magnet 11 and the media 15 are adsorbed. At this time, the media 15 is affected by the magnet 11, and the media 15 approaches the magnet 11. The support assembly provides stable support for the ball mill, ensuring the stability and safety of the ball mill during operation. The efficient grinding of quartz sand is ensured through reasonable grinding space design and the movement mode of the media 15.

[0044] During normal operation, the medium 15 will be brought to a certain height as the grinding cylinder 1 rotates, and then fall down to impact and grind the material. When the blocking plate 13 moves to a point where it does not overlap with the magnet 11, the medium 15 is magnetically connected to the magnet 11. On the one hand, the magnet 11 can produce a certain magnetic attraction on the medium 15, so that the medium 15 approaches the inner wall of the grinding cylinder 1 under the adsorption of the magnet 11, and the medium 15 grinds the material during its movement toward the magnet 11. On the other hand, the falling medium 15 is attracted to increase the acceleration of the medium 15, so that the medium 15 can produce a greater impact force on the quartz sand, thereby improving the crushing effect on the quartz sand. At the same time, the medium 15 close to the magnet 11 and the falling medium 15 collide with each other, thereby increasing the grinding effect of the medium 15 on the material, reducing the impact angle and strength of the medium 15 on the liner of the grinding cylinder 1, and reducing the wear rate of the liner of the grinding cylinder 1. When the medium 15 falls at a higher position, there is more horizontal displacement space, which makes the grinding More quartz sand in the cylinder 1 can be impacted by the medium 15, rather than being limited to the area near the landing point of the medium 15. Therefore, the quartz sand at different positions in the cylinder can be crushed, making the crushing process more uniform and reducing the situation where local quartz sand is not fully crushed. This uniform distribution helps to reduce blind spots or weak areas in the magnetic field and improve the efficiency of the use of the magnetic field; and when the blocking plate 13 moves to coincide with the magnet 11, the magnet 11 disconnects the force with the grinding cylinder 1 and the medium 15, and slides to the initial position under its own gravity and the gravity of the medium 15. The bracket 10 and the magnet 11 thereon are consistent with the center line of the grinding cylinder 1, thereby improving the stability of the movement of the magnet 11 and ensuring that the magnetic attraction generated by the magnet 11 can be effectively isolated under the action of the blocking plate 13. The blocking plate 13 is distributed in an annular shape and connected to the surface of the grinding cylinder 1, so that the magnet 11 intermittently adsorbs the medium 15. The intermittent operation of the magnet 11 can ensure that each part of the material can fully contact the medium 15.

[0045] Through the cooperation of the magnet 11, the baffle plate 13 and the medium 15, the medium 15 is magnetically connected to the magnet 11. On the one hand, the magnet 11 can produce a certain magnetic attraction to the medium 15, so that the medium 15 approaches the inner wall of the grinding cylinder 1 under the adsorption of the magnet 11, and the medium 15 grinds the material during the movement toward the magnet 11. On the other hand, the falling medium 15 is attracted to increase the acceleration of the medium 15, so that the medium 15 can produce a greater impact force on the quartz sand, thereby improving the crushing effect of the quartz sand. At the same time, the medium 15 close to the magnet 11 and the falling medium 15 are offset, thereby increasing the grinding effect of the medium 15 on the material.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
