Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, specifically a grinding equipment for quartz sand production. Background Technology

[0002] Quartz sand, a silicate mineral particle obtained by crushing and processing quartz stone, typically contains over 90% silicon dioxide (SiO). It is renowned for its high hardness, chemical inertness, excellent thermal stability, and remarkable wear resistance. These unique properties make quartz sand an indispensable core raw material in high-end industrial fields such as glass manufacturing, electronic semiconductors, and precision casting. The production process of quartz sand involves multiple steps, including key processes such as crushing, grinding, and screening. These steps work together to ensure the quality and applicability of quartz sand.

[0003] With current technology, quartz sand processing equipment can effectively crush, filter, and grind quartz sand. However, these devices often only perform single-pass crushing, limiting the thorough crushing of the quartz sand. Furthermore, many systems require additional screening machines to sieve the crushed quartz sand to ensure its particle size meets specific requirements. These issues lead to low efficiency in quartz sand production and make it difficult to guarantee the quality of the produced quartz sand. Utility Model Content

[0004] In order to overcome some of the problems mentioned in the background above, a grinding device for quartz sand production is provided.

[0005] The technical solution adopted by this utility model is as follows: A grinding equipment for quartz sand production includes a shell, a scraping mechanism and a cutting mechanism. The scraping mechanism is disposed inside the shell, and the cutting mechanism is disposed inside the scraping mechanism. The cutting mechanism is tangential to the scraping mechanism to crush quartz sand.

[0006] The housing is equipped with a sieve cylinder for screening the quartz sand obtained from grinding. The scraping mechanism includes multiple scrapers, which are slidably connected to the inner surface of the sieve cylinder. The scrapers are used to move the quartz stones inside the sieve cylinder.

[0007] Furthermore, the housing also includes a sealing cover, the top of which is provided with a feed inlet and the bottom of which is provided with a discharge outlet;

[0008] The screen cylinder is detachably connected to the sealing cover, and a collection bin is provided between the inner wall of the screen cylinder and the sealing cover. The bottom of the collection bin is connected to the discharge port.

[0009] Furthermore, it also includes a frame, a first motor and a second motor. The outer wall of the sealing cover is fixedly connected to the frame, and the cutting mechanism is connected to the frame. The first motor drives the scraping mechanism to rotate along the inner wall of the screen cylinder, and the second motor drives the cutting mechanism to move in the opposite direction to the scraping mechanism.

[0010] Furthermore, the scraping mechanism also includes a transmission wheel, a baffle, a positioning ring, and a fixing plate. The fixing plate is fixedly connected to both ends of the scraper and is slidably connected to the inner wall of the screen cylinder. The baffle is located on the outside of the fixing plate and is used to block both ends of the screen cylinder. The positioning ring is located in the middle of the two fixing plates and is fixedly connected to the scraper. The transmission wheel is located on the outside of one of the baffles and is connected to the first motor.

[0011] Furthermore, the cutting mechanism includes a hammer plate and a rotating shaft. Both ends of the rotating shaft pass through the scraping mechanism and are shaft-connected to the frame. The hammer plate is fixedly connected to the outer wall of the rotating shaft. One end of the rotating shaft is provided with a connecting wheel, which is drivenly connected to the second motor.

[0012] The scraper and the hammer rotate on the same trajectory, forming a shearing and crushing zone.

[0013] Furthermore, the end of the hammer plate is provided with a serrated blade.

[0014] Furthermore, the surface of the scraper is provided with protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The scraper pushes the incompletely ground quartz stone inside the screen cylinder, causing it to be further ground until the required fineness is achieved. The screen cylinder then screens the qualified quartz sand, making the quartz sand production process more refined, which improves both product quality and production efficiency.

[0017] The cutting and scraping mechanisms move in opposite directions, a design that ensures the quartz sand receives a finer and more uniform cut and grind during the grinding process. This design not only significantly improves the equipment's efficiency but also ensures a more uniform and efficient grinding process, thereby enhancing the final quality of the quartz sand.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1-5 As shown, in some embodiments, a grinding device for producing quartz sand includes a housing 2, a scraping mechanism 4, and a cutting mechanism 5. Specifically, the scraping mechanism 4 is disposed inside the housing 2, while the cutting mechanism 5 is disposed within the internal space of the scraping mechanism 4. These two mechanisms move tangentially to effectively crush the quartz stone to achieve the desired particle size. This design not only improves production efficiency but also ensures the quality of the quartz sand.

[0028] Specifically, a sieve cylinder 22 is specially designed inside the shell 2. Its main function is to screen the quartz sand obtained after grinding, ensuring that only qualified quartz sand that meets the standards can pass through, and improving the grinding efficiency of the quartz sand. In addition, the scraping mechanism 4 consists of multiple scrapers 43, which can be slidably connected to the inner surface of the sieve cylinder 22. The scrapers 43 push the incompletely ground quartz stone inside the sieve cylinder 22, causing it to be further ground inside the sieve cylinder 22 until the required fineness is achieved. This design makes the quartz sand production process more refined and greatly improves the quality of the product.

[0029] Furthermore, in some embodiments, the housing 2 also includes a sealing cover 21 with a feed inlet 1 at its top for easy feeding of raw quartz into the equipment for grinding. Additionally, the sealing cover 21 has a discharge outlet 8 at its bottom, ensuring that the ground quartz sand can be smoothly discharged from the equipment. This design not only improves production efficiency but also ensures the airtightness of the entire production process through the use of the sealing cover 21, effectively preventing dust diffusion and reducing environmental pollution.

[0030] The screen cylinder 22 and the sealing cover 21 are detachably connected, making maintenance and replacement of the screen cylinder 22 very convenient. When cleaning or replacement is needed, workers can easily remove the screen cylinder 22 from the sealing cover 21 for necessary maintenance or replacement. Furthermore, a collection bin is provided between the inner walls of the screen cylinder 22 and the sealing cover 21. The main function of this collection bin is to temporarily store the screened quartz sand. The bottom of the collection bin is connected to the discharge port 8, ensuring that the quartz sand can be directly discharged through the discharge port 8 after screening, further improving production efficiency.

[0031] Furthermore, in some embodiments, the grinding equipment also includes a frame 3, a first motor 6, and a second motor 7. Specifically, the outer wall of the sealing cover 21 is fixedly connected to the frame 3 to ensure the stability and durability of the sealing cover 21. The cutting mechanism 5 is connected to the frame 3, providing necessary support for the cutting mechanism 5, thus ensuring the stability and accuracy of the cutting mechanism 5 during operation.

[0032] The first motor 6 is fixedly connected to one end of the frame 3, while the second motor 7 is fixedly connected to the other end of the frame 3 to ensure stable power output.

[0033] During operation, the first motor 6 drives the scraping mechanism 4 to rotate continuously and evenly along the inner wall of the screen cylinder 22, ensuring that the quartz sand is fully and uniformly ground inside the screen cylinder 22. Simultaneously, the second motor 7 drives the cutting mechanism 5 to move in the opposite direction to the scraping mechanism 4. This reverse motion design allows for finer and more uniform cutting and grinding of the quartz sand during the grinding process. This design not only significantly improves the equipment's efficiency but also ensures a more uniform and efficient grinding process for the quartz sand, thereby enhancing the final quality of the quartz sand.

[0034] Furthermore, in some embodiments, the scraping mechanism 4 also includes a transmission wheel 41, a baffle 42, a positioning ring 44, and a fixing plate 45. Specifically, the fixing plate 45 is disposed at both ends of the scraper 43 and fixedly connected to it, thereby fixing the scraper 43 to ensure the stability of its position during grinding. These fixing plates 45 can slide against the inner wall of the screen cylinder 22, ensuring that the scraper 43 can scrape up the unground quartz stone against the inner wall of the screen cylinder 22, pushing the quartz stone into a cyclical motion for further grinding, thus ensuring the quality of the quartz sand grinding. In addition, as the scraper 43 moves, it can also remove quartz sand clogging the screen holes on the surface of the screen cylinder 22, preventing clogging of the screen cylinder 22.

[0035] Baffle 42 is positioned on the outside of fixed plate 45, and its main function is to seal both ends of screen cylinder 22 to prevent quartz stone from leaking during the grinding process. In addition, positioning ring 44 is positioned in the middle of the two fixed plates 45, and it is fixedly connected to scraper 43 to ensure that scraper 43 is in the correct position.

[0036] The drive wheel 41 is located on the outside of one of the baffles 42. It is connected to the first motor 6 through a transmission to drive the movement of the scraping mechanism 4, so as to achieve efficient grinding of quartz sand.

[0037] Furthermore, in some embodiments, the cutting mechanism 5 includes a hammer plate 51 and a rotating shaft 53. Both ends of this rotating shaft 53 are designed to pass through the scraping mechanism 4 and be axially connected to the frame 3. This ensures that the rotating shaft 53 can rotate relative to the frame 3 and the scraping mechanism 4.

[0038] Specifically, multiple hammer plates 51 are fixedly installed on the outer wall of the rotating shaft 53, and these hammer plates 51 can rotate with the rotating shaft 53. In addition, a connecting wheel 52 is provided at one end of the rotating shaft 53, which is connected to the second motor 7 through a transmission device to realize the transmission of power. This design enables the rotating shaft 53 to efficiently drive the hammer plates 51, ensuring uniform crushing of materials such as quartz sand during the grinding process, thereby improving production efficiency and product quality.

[0039] The scraper 43 is designed to coincide with the rotation trajectory of the hammer 51, so that during the rotation of the hammer 51, the scraper 43 can work in tandem with it to form a shearing and crushing zone. Within this zone, the quartz stone is effectively sheared and crushed to achieve the desired particle size. This collaborative working method not only improves crushing efficiency, but also, by precisely controlling the relative position and movement of the scraper 43 and the hammer 51, can further optimize the crushing effect, ensuring a more uniform particle size distribution of the quartz sand to meet the requirements.

[0040] Furthermore, in some embodiments, the end of the hammer plate 51 is designed with a serrated blade structure. This unique design allows the hammer plate 51 to more effectively cut and crush quartz particles when grinding quartz, thereby improving grinding efficiency and the quality of quartz sand production. The serrated blade structure not only increases the contact area between the hammer plate 51 and the quartz particles, but also enables finer cutting of the quartz particles through its sharp edges.

[0041] Furthermore, in some embodiments, protrusions are provided on the surface of the scraper 43. This protrusion design can effectively increase the friction between the scraper 43 and the material, thereby improving grinding efficiency. At the same time, this design can also better grind the quartz particles when interacting with the hammer plate 51, ensuring the stability and uniformity of the grinding process.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
