Description

Technical Field

[0001] This utility model relates to the field of basalt fiber processing devices, specifically to a basalt fiber crushing device. Background Technology

[0002] Traditional copper and copper alloy materials suffer from low coefficients of friction and poor wear resistance, heat resistance, and corrosion resistance, which limit their application in braking friction. To overcome these limitations, research has begun on preparing copper-based composite materials using copper alloys as the matrix and adding reinforcing phases such as particles, whiskers, and fibers. These composite materials not only improve hardness but also increase the coefficient of friction, optimizing tribological performance. Basalt fiber, as a novel inorganic, environmentally friendly, and high-performance fiber material, has been widely studied and applied due to its excellent mechanical, electrical, and thermal properties. The initial shape of basalt fiber is a continuous fiber formed by melting basalt rock at high temperature and then drawing it at high speed through a platinum-rhodium alloy spinneret.

[0003] Because basalt fiber possesses similar mechanical, thermal, and other properties to inorganic high-performance fibers such as carbon fiber, and its cost is significantly lower, it can be used as a substitute. In the preparation of copper-based composites, to better integrate basalt fiber with the copper alloy matrix, the basalt fiber is chopped and ground to ensure more uniform dispersion within the matrix, thereby improving the composite's uniformity and performance. However, due to the high toughness of basalt fiber, the particle size after grinding is uneven. Current technologies often involve increasing grinding time and intensity to further refine the basalt fiber particles, but this still results in significant particle size variations and low grinding efficiency.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0026] Example like Figure 1 and Figure 3As shown, this utility model embodiment provides a basalt fiber crushing device, including: a box body 1, a grinding body 5, and a sieve plate 6. The box body 1 has the function of housing and supporting, and its interior is provided with a grinding chamber 2 and a sieve chamber 3 that are connected vertically. The sieve chamber 3 is located below the grinding chamber 2. The upper end of the box body 1 is provided with a feed inlet 4. The grinding body 5 is disposed in the grinding chamber 2 and is configured to grind the basalt fiber fed into it through the feed inlet 4. The sieve plate 6 is disposed in the sieve chamber 3 and is configured to sieve the basalt fiber after it has been ground in the grinding chamber 2. The sieve plate 6 is provided with a plurality of filter holes 7, each filter hole 7 being of equal size. The sieve chamber 3 is provided with a discharge mechanism 8, which is located below the sieve plate 6. Specifically, the box body 1 is the frame structure of the entire device, and the feed port 4 is located at the upper end of the box body 1 for feeding basalt fibers; the grinding body 5 physically grinds the basalt fibers fed from the feed port 4 to achieve the required particle size; the sieve plate 6 sieves the basalt fibers after grinding in the grinding chamber 2. Fibers that meet the size of the filter hole 7 pass through the filter hole 7 and are collected by the discharge mechanism 8. Fibers that do not meet the size of the filter hole 7 remain in the sieve chamber 3 and can be taken out and put back into the grinding chamber 2 for re-grinding.

[0027] In this embodiment of the invention, the uniformity of basalt fiber particle size is ensured by using filter holes 7 of equal size. Timely separation and collection of particles meeting the particle size requirements improves grinding efficiency, while re-grinding of particles that do not meet the size requirements reduces resource waste. It should be noted that the number, size, and distribution of the filter holes 7 on the sieve plate 6 are not limited here; they can be set according to actual needs, as long as the preset sieving effect is achieved.

[0028] To improve the automation efficiency of the device, the pulverizing device provided in this embodiment of the invention further includes a pipe mechanism 9. A gap exists between the grinding body 5 and the sieve plate 6. One end of the pipe mechanism 9 connects to the gap between the grinding body 5 and the sieve plate 6, and the other end connects to the upper region of the grinding body 5. A fan 10 is installed on the pipe mechanism 9. The fan 10 is used to transport the basalt fibers above the sieve plate 6 to the grinding body 5 for further grinding. Specifically, the fan 10 on the pipe mechanism 9 provides power to transport the basalt fibers from above the sieve plate 6 to above the grinding body 5 for further grinding. By incorporating the fan 10 and the pipe mechanism 9, this embodiment of the invention enables the device to automatically return fibers that have not passed through the filter holes 7 to the grinding chamber 2, reducing manual intervention.

[0029] Furthermore, such as Figure 2As shown, a connecting rod 11 is provided at the bottom of the grinding body 5. The connecting rod 11 passes through the sieve plate 6, and a motor 12 is connected to the connecting rod 11. The motor 12 is configured to drive the connecting rod 11 to rotate the grinding body 5. In this way, the connecting rod 11 can serve as a mechanical connecting component, transmitting the power of the motor 12 to the grinding body 5, enabling it to rotate. In use, after the motor 12 starts, it transmits the power to the grinding body 5 through the connecting rod 11. The rotation of the connecting rod 11 causes the grinding body 5 to rotate within the grinding chamber 2, grinding the input basalt fibers. The ground fibers fall into the sieve chamber 3 through the gap between the grinding body 5 and the sieve plate 6. The sieve plate 6 sieves the fibers. Fibers that meet the size of the filter holes 7 are collected by the discharge mechanism 8 through the filter holes 7, while fibers that do not meet the size remain in the sieve chamber 3. The blower 10 transports the fibers above the sieve plate 6 that did not pass through the filter holes 7 back to the grinding body 5 through the pipeline mechanism 9 for further grinding.

[0030] In a preferred embodiment of this utility model, the sieving chamber 3 has a structure with a gradually decreasing cross-section from top to bottom. The sieve plate 6 is movably disposed at the upper end of the sieve chamber 3, and the sieve plate 6 is also configured to limit the grinding body 5 within the grinding chamber 2. As the cross-section of the sieve chamber 3 decreases, it guides the fiber particles passing through the filter holes 7, efficiently guiding the fiber particles to the discharge mechanism 8 for efficient discharge. It should be noted that the discharge mechanism 8 may have a discharge through hole 13 at the bottom of the sieve chamber 3, and a discharge valve may be installed at the discharge through hole 13. During operation, the opening and closing of the discharge valve is controlled according to actual needs. Furthermore, in this embodiment of the utility model, since the sieve chamber 3 has a structure with a gradually decreasing cross-section from top to bottom, the sieve plate 6 can be movably placed at the upper end of the sieve chamber 3. The cavity wall of the sieve chamber 3 provides stable support for the sieve plate 6, and also simplifies the installation and disassembly of the sieve plate 6.

[0031] To ensure that the grinding body 5 can rotate relative to the sieve plate 6, for example, a through hole 13 can be provided on the sieve plate 6, through which the connecting rod 11 passes and can rotate. A limit block 14 is provided on the connecting rod 11, the lateral dimension of the limit block 14 being larger than the lateral dimension of the through hole 13, and the through hole 13 limiting the limit block 14 above it. Specifically, the through hole 13 allows the connecting rod 11 to pass through and rotate within it, providing space for the connecting rod 11 to move. The size of the limit block 14 ensures that it cannot pass through the through hole 13, thus limiting the distance between the grinding body 5 and the sieve plate 6 and preventing collisions between them. Since the connecting rod 11 connects the grinding body 5 and the sieve plate 6, the sieve plate 6 can efficiently absorb the vibration energy of the rotating grinding body 5, thereby achieving sieving. Importantly, in this embodiment of the invention, the sieve plate 6 can support the grinding body 5 through the connecting rod 11. The grinding body 5 can rotate stably at a fixed vertical height without the need for other support structures, thus achieving grinding. Due to the movable design of the sieve plate 6, the grinding body 5 can also be flexibly installed and disassembled, and even different specifications of grinding bodies 5 can be replaced as needed, improving the flexibility of the device.

[0032] To better demonstrate the flexible functionality of this utility model embodiment, a side cover 19 can be provided on the side of the box body 1, exemplarily. The side cover 19 is configured to control the opening and closing of the side of the grinding chamber 2 and the side of the sieving chamber 3, so that the grinding body 5 and the sieve plate 6 can be installed and disassembled on the side of the box body 1. Specifically, the side cover 19 can be opened and closed according to actual needs. As a preferred embodiment of this utility model, a groove 15 is also provided on the sieve plate 6. The groove 15 is located above the through hole 13. The lateral dimension of the groove 15 is larger than the lateral dimension of the limiting block 14, allowing the limiting block 14 to rotate within the groove 15. The motor 12 is located at the lower end of the sieve plate 6. The groove 15 allows the limiting block 14 to rotate within it, increasing the flexibility of the connecting rod 11 while maintaining the stability of the limiting block 14. This structure allows the connecting rod 11 to have a certain range of motion when transmitting power, reducing wear and improving durability, and allowing the limiting block 14 to rotate within the groove 15 without exceeding the boundary of the sieve plate 6. The motor 12 is located at the lower end of the sieve plate 6 to prevent it from obstructing the rotation of the grinding body 5.

[0033] More preferably, there is a gap between the grinding body 5 and the inner wall of the grinding chamber 2, and the distance between the grinding body 5 and the inner wall of the grinding chamber 2 gradually decreases from top to bottom. This structure allows the basalt fiber particles to fall in a gradually refined grinding process, improving grinding efficiency and reducing component wear. For example, the grinding body 5 can be a conical structure, with the cross-sectional dimension of its upper surface being smaller than that of its lower surface. The conical grinding body 5 can grind the fibers to different degrees on different cross-sections, improving grinding efficiency. Simultaneously, this structure can lower the center of gravity of the grinding body 5, improving the stability of the grinding body 5 during rotational grinding.

[0034] Furthermore, such as Figure 1 and 4 As shown, the main body 1 of the chamber also includes a cutting chamber 16, located above the grinding chamber 2. A cutting roller 17 is installed within the cutting chamber 16 to cut the basalt fibers fed into the feed port 4. The cutting chamber 16 is connected to the grinding chamber 2, and is configured to cut long blocks of basalt fibers into shorter blocks before conveying them to the grinding chamber 2 for grinding. Specifically, the addition of the cutting chamber 16 and the cutting roller 17 allows the basalt fibers to be cut into shorter blocks before entering the grinding chamber 2, which helps improve grinding efficiency. Because the fibers are pre-cut, the wear of the grinding body 5 during the grinding process is reduced, thereby extending the service life of the grinding body 5. Simultaneously, the cut fiber blocks are more uniform in size, contributing to improved fiber uniformity after grinding. Preferably, the cutting roller 17 can be adjusted in cutting length as needed, allowing the device to adapt to the processing of basalt fibers of different lengths. Meanwhile, a detachable end cap 18 can be provided on the feed inlet 4. The end cap 18 can be configured as a hinged rotating structure to enhance the safety of the device and help reduce dust leakage, protect the working environment, and protect the components inside the box body 1. More preferably, support feet 20 can be provided at the bottom of the box body 1 as needed to provide stable support for the entire device.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing techniques, and processes are omitted to avoid unnecessarily limiting the utility model.
