Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand ball milling equipment, specifically a fine grinding device for new energy quartz sand. Background Technology

[0002] In the new energy industry, quartz sand is a key basic material, especially widely used in photovoltaics and lithium batteries. High-purity quartz sand is needed to manufacture quartz crucibles for photovoltaic silicon wafer production, and ultrafine quartz sand is also relied upon for improving the performance of lithium battery separator coatings. Fine grinding of quartz sand can achieve micron-level particle size and high purity standards, meeting the requirements of new energy products for material stability and precision, and providing fundamental support for the efficient operation of new energy equipment.

[0003] Utility model patent CN220004256U discloses a special grinding mill for quartz sand, which includes a drive support base, a ball mill drum, and a screening output box. This special grinding mill for quartz sand uses a closed screening output box for the ground quartz sand. After grinding, the quartz sand enters the screening output box, and a rotating screening screen driven by a drive motor screens the ground products of different coarse and fine diameters. Different qualities of ground products are then output from different outlet troughs at the bottom, achieving screening and closed output of the ground products. This improves output quality and avoids waste and contamination caused by external factors. By using a rotating screening screen with an arc shape, while the fine ground products are being screened into the bottom channel, the arc shape assists in rotating the coarser ground products until they fall into the abrasive grain outlet trough at the left end. This achieves screening and sorting of ground products of different diameters, providing a simple and effective screening process.

[0004] When the grinding balls in the ball mill drum of this special quartz sand grinding machine need to be replenished due to wear, the machine must be stopped and the feed end or related opening of the ball mill drum must be opened before the grinding balls can be added manually. This not only involves cumbersome operation steps, but also causes the grinding operation to be interrupted. At the same time, external dust can easily enter the ball mill drum during the replenishment process, which may affect the purity of the quartz sand. In view of this, we propose a new energy quartz sand fine grinding device. Utility Model Content

[0005] The purpose of this invention is to provide a fine grinding device for new energy quartz sand to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A new energy quartz sand fine grinding device includes a ball mill cylinder. The ball mill cylinder has a feeding port coaxially provided at its first end. Both the first and last ends of the ball mill cylinder are rotatably connected to a support frame. A grinding ball storage mechanism for storing grinding balls is provided at the first end of the ball mill cylinder. The grinding ball storage mechanism includes a fixed base fixed on the front support frame, several storage sleeves sleeved on the top of the fixed base, a feeding pipe connected to the bottom of the fixed base, and several feeding components rotatably connected to the front end of the fixed base.

[0008] The fixed base has a cavity, and the top of the fixed base has several sleeve holes that communicate with the cavity. The storage sleeve has a hollow cylindrical structure that is open at the top and bottom. The bottom end of the storage sleeve is fitted and fixed in the sleeve hole. The front end face of the fixed base has several rotating cavities that communicate with the sleeve holes respectively. The dispensing component is fitted in the rotating cavity. The dispensing component includes a rotating base and a lever fixed to the outer end of the rotating base. The outer circumferential surface of the rotating base has a through groove. By moving the lever, the lever can drive the rotating base to rotate circumferentially in the rotating cavity, thereby controlling the opening and closing state of the groove and the sleeve hole.

[0009] The first end of the feeding tube is connected to the bottom end of the cavity, and the end of the feeding tube extends into the ball mill cylinder from the feeding port.

[0010] Preferably, the bottom of the fixed base is provided with downward protruding support legs on both the left and right sides, and the bottom ends of the two support legs are fixedly connected to the top of the support frame located on the front side.

[0012] Preferably, the sleeve hole is a vertical hole, the number of feeding tubes is the same as the number of sleeve holes, and several sleeve holes are evenly spaced along the length direction on the top surface of the fixed base. The number of rotating cavities is equal to the number of sleeve holes and their positions correspond one-to-one. The rotating cavities are perpendicular to the sleeve holes.

[0013] In this setup, the evenly distributed sleeve holes facilitate the stable installation of multiple storage sleeves. The rotating cavity corresponds one-to-one with the sleeve holes, and the opening and closing of the corresponding sleeve holes can be independently controlled by a single delivery component, flexibly adjusting the falling state of the grinding balls.

[0014] Preferably, the bottom of the cavity slopes downward from the left and right ends of the cavity towards the middle of the cavity, and the bottom center of the fixed base is provided with a discharge port that communicates with the bottom of the cavity, and the first end of the feeding pipe is sleeved and fixed inside the discharge port.

[0015] In this setup, the inclined bottom of the cavity guides the grinding balls to converge towards the center of the cavity, and the discharge port ensures that the grinding balls accurately enter the feeding pipe, preventing the grinding balls from accumulating inside the cavity.

[0016] Preferably, the feeding pipe is bent, and several support rods are fixed between the feeding pipe and the support frame located on the front side;

[0017] In this setup, the bent feed tube is adapted to the positional relationship between the ball mill cylinder and the fixed base, and the support rod enhances the stability of the feed tube and prevents the feed tube from deforming due to weight or impact from the grinding balls.

[0018] Preferably, the rotating seat has a cylindrical structure, the groove width is the same as the hole diameter, the front end of the lever is fixed with a square shaft, the square shaft is inserted into the end of the rotating seat and fixedly connected to the rotating seat by bolts, and the end of the lever faces the same direction as the groove, so as to visually display the open / closed state of the groove and the hole.

[0019] In this setup, the cylindrical rotating seat facilitates smooth rotation, the matching size of the groove and the sleeve hole prevents the grinding ball from getting stuck, the square shaft ensures that the handle rotates synchronously with the rotating seat, and the orientation of the handle allows for a direct indication of the groove's on / off status.

[0020] Preferably, a baffle is bolted to the front end face of the fixed seat, the baffle covers the opening of the rotating cavity, and the baffle has a plurality of rotating holes corresponding to the rotating cavity. The head end of the lever passes through the rotating hole and can rotate in the rotating hole. A first stop rod is fixed on the baffle above the rotating hole, and a second stop rod is fixed on the baffle to the right of the rotating hole. The tail end of the lever is located between the first stop rod and the second stop rod. The first stop rod and the second stop rod are used to limit the rotation angle of the lever.

[0021] In this setup, the baffle prevents dust from entering the rotating chamber, the rotating hole provides rotation space for the lever, and the first and second stops limit the rotation angle of the lever to ensure precise opening and closing of the slot.

[0022] Preferably, a fixing frame is installed at the top of the fixing base, a plurality of storage sleeves are fitted inside the fixing frame, a cover plate is hinged to the top of the fixing frame, and a handle is installed at the top of the cover plate;

[0023] In this setup, the mounting bracket enhances the stability of the storage sleeve, the cover prevents dust from contaminating the grinding balls inside the storage sleeve, and the handle facilitates opening the cover to replenish the grinding balls.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This new energy quartz sand fine grinding device, through the setting of a grinding ball storage mechanism, allows the grinding balls to be pre-stored in the storage sleeve, eliminating the need for frequent external handling or temporary preparation of grinding balls. With the rotating seat and handle of the feeding component, the opening and closing of the trough and the sleeve hole can be controlled simply by turning the handle, realizing the feeding of grinding balls into the ball mill without stopping the machine. At the same time, the storage and feeding processes are carried out in a relatively closed structure, reducing the risk of external dust entering the ball mill. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] Please see Figures 1-6 A new energy quartz sand fine grinding device includes a ball mill 100. The ball mill 100 has a feeding port 110 coaxially provided at its first end. Both the first and last ends of the ball mill 100 are rotatably connected to a support frame 120. A grinding ball storage mechanism 200 for storing grinding balls is provided at the first end of the ball mill 100. The grinding ball storage mechanism 200 includes a fixed seat 210 fixed on the front support frame 120, several storage sleeves 220 sleeved on the top of the fixed seat 210, a feeding pipe 230 connected to the bottom of the fixed seat 210, and several feeding components 240 rotatably connected to the front end of the fixed seat 210. The grinding ball storage mechanism 200 can realize the pre-storage and directional feeding of grinding balls, eliminating the need for frequent external handling of grinding balls and preventing external dust from entering the ball mill 100 when manually adding grinding balls.

[0038] like Figures 1-3As shown, in this utility model, the bottom of the fixed base 210 has downwardly protruding support legs 211 on both the left and right edges. The bottom ends of the two support legs 211 are fixedly connected to the top of the support frame 120 located on the front side. The support legs 211 can provide stable support for the fixed base 210, keeping the fixed base 210 and the support frame 120 relatively fixed, and preventing the fixed base 210 from shifting during use. A cavity 212 is opened inside the fixed base 210. The cavity 212 can serve as a transition space for the grinding balls to flow from the storage sleeve 220 to the feeding pipe 230, facilitating the grinding balls to gather and enter the feeding pipe 230. The top of the fixed base 210 has several sleeve holes 213 that communicate with the cavity 212. The sleeve holes 213 provide an installation position for the storage sleeve 220, and at the same time, allow the grinding balls in the storage sleeve 220 to fall smoothly into the cavity 212. The storage sleeve 220 has a transparent hollow cylindrical structure with open top and bottom. The transparent design facilitates... Operators can visually observe the remaining amount of grinding balls in the storage sleeve 220 and replenish the grinding balls in a timely manner. The bottom end of the storage sleeve 220 is fitted and fixed in the sleeve hole 213. The sleeve hole 213 is a vertical hole. The number of feeding pipes 230 is the same as the number of sleeve holes 213. Several sleeve holes 213 are evenly spaced along the length of the top surface of the fixed base 210. The even distribution of the sleeve holes 213 can ensure the stable installation of multiple storage sleeves 220, and at the same time ensure that the grinding balls can fall evenly into the cavity 212, avoiding the accumulation and blockage of grinding balls in the cavity 212.

[0039] like Figure 2 and Figure 3 As shown, specifically, the bottom of cavity 212 slopes gradually downwards from both ends towards the center. This sloped bottom allows the grinding balls to converge towards the center of cavity 212 using gravity, facilitating their smooth entry into the discharge port 215. The bottom center of the fixed base 210 has a discharge port 215 connected to the bottom of cavity 212, providing a channel for the grinding balls within cavity 212 to flow into the feeding pipe 230. The first end of the feeding pipe 230 is fitted with and fixed. Inside the discharge port 215, the feeding pipe 230 is bent. This bent design adapts to the positional relationship between the ball mill cylinder 100 and the fixed base 210, allowing the grinding balls to be smoothly conveyed from the fixed base 210 into the ball mill cylinder 100. The first end of the feeding pipe 230 is connected to the bottom end of the cavity 212, and the second end of the feeding pipe 230 extends into the ball mill cylinder 100 from the feeding port 110. The direct insertion of the feeding pipe 230 into the ball mill cylinder 100 ensures that the grinding balls enter the ball mill cylinder 100 accurately, preventing the grinding balls from spilling during the conveying process. Several support rods 231 are fixed between the feeding pipe 230 and the support frame 120 located on the front side. The support rods 231 can provide auxiliary fixation for the feeding pipe 230, enhance the stability of the feeding pipe 230, and prevent the feeding pipe 230 from deforming or shifting due to its own weight or the impact of the grinding balls.

[0040] like Figure 3 and Figure 5 As shown, further, the front end face of the fixed base 210 is provided with a plurality of rotating cavities 214 that are respectively connected to the sleeve holes 213. The rotating cavities 214 provide installation and rotation space for the dispensing component 240. The number of rotating cavities 214 is equal to the number of sleeve holes 213 and their positions correspond one-to-one. The rotating cavities 214 are perpendicular to the sleeve holes 213. The one-to-one correspondence between the rotating cavities 214 and the sleeve holes 213 can realize the on / off control of a single dispensing component 240 on a single sleeve hole 213, and flexibly adjust the falling state of the grinding balls in different storage sleeves 220. The dispensing component 240 is fitted in the rotating cavity 214. The dispensing component 240 includes a rotating seat 241 and a lever 242 fixed to the outer end of the rotating seat 241. The lever 242 allows the operator to manually control the rotation of the rotating seat 241. A through groove 2411 is formed on the outer circumferential surface of the rotating seat 241. When the rotating seat 241 rotates to a specific angle, the groove 2411 communicates with the sleeve hole 213, allowing the grinding balls in the storage sleeve 220 to fall into the cavity 212 through the groove 2411. By moving the lever 242, the lever 242 can drive the rotating seat 241 to rotate circumferentially in the rotating cavity 214, thereby controlling the opening and closing of the groove 2411 and the sleeve hole 213. The dispensing of grinding balls can be opened and closed without stopping the machine, ensuring the continuity of the grinding operation.

[0041] like Figure 5 As shown, the rotating seat 241 has a cylindrical structure, which allows it to rotate smoothly within the rotating cavity 214, reducing rotational resistance. The groove width of the slot 2411 is the same as the diameter of the sleeve hole 213. This matching ensures that the grinding ball passes smoothly through the slot 2411 and the sleeve hole 213, preventing the grinding ball from getting stuck due to size mismatch. A square shaft 2421 is fixed to the end of the handle 242. The square shaft 2421 is inserted into the end of the rotating seat 241 and fixedly connected to the rotating seat 241 with bolts. The connection between the square shaft 2421 and the bolts ensures that the handle 242 and the rotating seat 241 rotate synchronously, preventing relative sliding between them. The direction of the end of the handle 242 is the same as the direction of the slot 2411, which is used to visually display the connection status between the slot 2411 and the sleeve hole 213. Operators can quickly determine whether the slot 2411 is connected to the sleeve hole 213 by observing the direction of the end of the handle 242, without disassembling the device for inspection.

[0042] like Figures 2-5As shown, it is worth noting that a baffle 216 is bolted to the front end face of the fixed base 210. The baffle 216 covers the opening of the rotating cavity 214, preventing external dust from entering the rotating cavity 214 and preventing the rotating base 241 from falling out of the rotating cavity 214. The baffle 216 has several rotating holes 2161 corresponding to the rotating cavity 214. The rotating holes 2161 provide a passage for the lever 242 to pass through and allow the lever 242 to rotate within the holes. The tip of the lever 242 passes through the rotating hole 2161 and can rotate within the rotating hole 2161. A first stop bar 2162 is fixed on the baffle 216 above the rotating hole 2161. A second stop bar 2163 is fixed on the baffle 216 on the right side of the moving hole 2161. The tail end of the lever 242 is located between the first stop bar 2162 and the second stop bar 2163. The first stop bar 2162 and the second stop bar 2163 are used to limit the rotation angle of the lever 242. When the end of the lever 242 rotates and touches the first stop bar 2162, the groove 2411 is connected to the sleeve hole 213. When the end of the lever 242 rotates and touches the second stop bar 2163, the groove 2411 is offset from the sleeve hole 213. This precisely controls the opening and closing state of the groove 2411 and the sleeve hole 213, and avoids the groove 2411 and the sleeve hole 213 from being misaligned due to the excessive rotation angle of the lever 242.

[0043] like Figure 2 and Figure 6 As shown, it is worth noting that a fixing frame 250 is installed at the top of the fixing base 210, and several storage sleeves 220 are fitted inside the fixing frame 250. The fixing frame 250 can centrally fix multiple storage sleeves 220, enhance the installation stability of the storage sleeves 220, and prevent the storage sleeves 220 from tipping over. A cover plate 251 is hinged to the top of the fixing frame 250. The cover plate 251 can cover the top of the fixing frame 250 to prevent external dust from falling into the storage sleeves 220 and contaminating the grinding balls. A handle 252 is installed at the top of the cover plate 251. The handle 252 makes it easy for operators to open or close the cover plate 251 and convenient to add grinding balls to the storage sleeves 220.

[0044] In this embodiment of the new energy quartz sand fine grinding device, the operator first opens the cover plate 251 using handle 252 and loads the grinding balls into each storage sleeve 220. Then, the cover plate 251 is closed. At this time, the grinding balls are temporarily stored in the storage sleeve 220 because the storage sleeve 220 is connected to the sleeve hole 213 and is blocked by the rotating seat 241 in the feeding component 240. Then, when grinding balls need to be replenished in the ball mill 100, the operator moves the dial 242, causing the dial 242 to drive the rotating seat 241 to rotate within the rotating cavity 214 until the end of the dial 242 contacts the first stop bar 2162. At this time, the trough 2411 and the sleeve hole 2162... 3. The grinding balls in the storage sleeve 220 fall into the cavity 212 through the sleeve hole 213 and the trough 2411 in sequence. Then, the grinding balls in the cavity 212 converge towards the center under the guidance of the inclined bottom of the cavity, enter the feeding pipe 230 through the discharge port 215, and are then transported to the ball mill 100 through the feeding pipe 230. Finally, when the grinding balls are replenished to the required amount, the operator reverses the lever 242 until the end of the lever 242 touches the second stop 2163. At this time, the trough 2411 and the sleeve hole 213 are misaligned, the grinding balls stop falling, and one grinding ball replenishment operation is completed. The ball mill 100 does not need to be stopped during the whole process and can continue to carry out grinding operations.
