Description

Technical Field

[0001] The utility model relates to the technical field of quartz processing, in particular to a new type of vertical crushing and screening device for fused quartz. Background Art

[0002] Fused quartz is the amorphous state of silicon oxide and is a typical glass. Its atomic structure is long-range disordered. The usage of fused quartz materials in precision casting shells in developed foreign countries such as the United States and Japan has been increasing year by year. It is an ideal engineering application material. Since the raw materials need to be crushed during the processing of fused quartz, a crushing device is required.

[0003] After retrieval, the patent with the publication number CN214863836U discloses a new type of vertical crushing and screening device for fused quartz. By setting a folding rod, a pull rod, a connecting rod, a movable rod, a resisting block, a pressing block and a shaft rod, when the motor is started, the folding rod rotates, driving the pull rod and the shaft rod to move, making the connecting rod and the shaft rod swing, and the movable rod moves, so that the resisting block and the pressing block squeeze and crush the fused quartz in the fixed cylinder. The two resisting blocks squeeze and crush the fused quartz in opposite directions, and the pressing block crushes the fused quartz in the fixed cylinder back and forth, so that the crushing effect on the fused quartz is better.

[0004] The crushing structure in this patent has a certain practicality, but there is still room for improvement. For example: in this patent, components such as the resisting block and the pressing block are used to squeeze and crush the quartz raw materials. All quartz raw materials of different sizes are placed together for crushing operations. However, during the crushing process, some larger quartz raw materials are relatively hard and are difficult to be completely crushed when being squeezed and crushed. Therefore, these larger quartz raw materials will provide a protection space for those smaller quartz raw materials, making it difficult for the resisting block and the pressing block to contact the smaller quartz raw materials, resulting in incomplete crushing of these quartz raw materials. The utility model has made certain improvements to this. Summary of the Utility Model

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. After the quartz raw material falls from the feed hopper, it first contacts the sieve plate. At this time, the smaller quartz raw material falls on the right side of the partition frame through the sieve holes and will not fall to the position of the crushing roller due to the blockage of the baffle, while the larger quartz raw material falls on the left side of the partition frame through the inclination of the sieve plate, so that the quartz raw materials of different sizes can be screened and crushed, making the crushing effect of the quartz raw material better and more thorough;

[0018] 2. When the quartz raw material falls on the sieve plate, the sieve plate is subjected to a downward impact force, which will drive the slider to slide downward on the surface of the round rod. At this time, the slider can squeeze the lower spring to generate a reaction force, and at the same time produce a buffering effect, avoiding the situation that the sieve plate is damaged and broken due to being subjected to a large impact force for a long time, thereby extending the service life of the sieve plate.

The upper surface of the base 1 is fixedly connected with a vertical frame 2. The upper surface of the vertical frame 2 is fixedly connected with a feeding hopper 3. A through hole is opened at a position corresponding to the upper surface of the vertical frame 2 and the feeding hopper 3. The quartz raw material enters the interior of the vertical frame through the feeding hopper 3. A sliding groove is opened on the inner wall of the vertical frame 2, and a screening component is slidably connected to the inner wall of the sliding groove. The screening component includes a slider 4, and the slider 4 is slidably connected to the inner wall of the sliding groove. The left side of the slider 4 is fixedly connected with a sieve plate 7, and the position of the feeding hopper 3 corresponds to the position of the sieve plate 7. A plurality of sieve holes are opened on the upper surface of the sieve plate 7. After the quartz raw material contacts the sieve plate 7, the quartz raw materials of different sizes can be screened. The lower surface of the sieve plate 7 is fixedly connected with a baffle 8. The inner bottom wall of the vertical frame 2 is fixedly connected with a partition frame 9. The quartz raw materials under the feet fall on the right side of the partition frame 9 through the sieve holes, while the larger quartz raw materials fall on the left side of the partition frame 9. The baffle 8 can ensure that the smaller quartz raw materials will not fall on the left side position of the partition frame 9. A strip-shaped groove is opened on the upper surface of the partition frame 9, and the baffle 8 is adapted to the strip-shaped groove on the upper surface of the partition frame 9 and is slidably connected to the inner wall of the strip-shaped groove. The inner bottom wall of the vertical frame 2 is fixedly connected with a triangular guiding plate 10. The triangular guiding plate 10 can ensure that the quartz raw materials will not fall on the horizontal position at the bottom of the vertical frame 2 and cannot be crushed;

[0026] The right inner wall of the vertical frame 2 is fixedly connected with a trapezoidal guiding frame 11. A circular groove is opened on the lower surface of the trapezoidal guiding frame 11. The inner top wall of the circular groove is fixedly connected with a hydraulic push rod 12. The output end of the hydraulic push rod 12 is fixedly connected with a pressing plate 13. The hydraulic push rod 12 can drive the pressing plate 13 to descend and crush the smaller quartz raw materials. Two driving motors 14 are fixedly connected to the back surface of the vertical frame 2. Two transmission shafts 15 are rotatably connected to the front and back inner walls of the vertical frame 2. The output ends of the two driving motors 14 are respectively fixedly connected to the rear ends of the two transmission shafts 15. Two circular through holes adapted to the transmission shafts 15 are opened on the back surface of the vertical frame 2. A plurality of friction balls 17 are fixedly connected to the surface of each of the two transmission shafts 15. The driving motors 14 can drive the two crushing rollers 16 to rotate, thereby crushing the larger quartz raw materials;

[0027] A blanking chute is provided on the front surface of the vertical frame 2. A blanking plate 18 is slidably connected to the inner wall of the blanking chute. Two blanking holes are provided at positions corresponding to the inner bottom wall and the lower surface of the vertical frame 2 and opposite to the blanking chute. The size of the pressing plate 13 is the same as that of the blanking hole, and the position of the pressing plate 13 corresponds to the position of the blanking hole. A rectangular groove is provided on the front surface of the base 1. A blanking frame 19 is slidably connected to the inner wall of the rectangular groove. The blanking plate 18 can serve as the bottom support of the pressing plate 13 to crush smaller quartz raw materials. At the same time, after the blanking plate 18 is pulled out, the crushed quartz raw materials can directly fall into the blanking frame 19.

[0028] Example 2: Refer to Figure 1 and Figure 2 , a round rod 5 is fixedly connected to the inner wall of the chute. A circular hole adapted to the round rod 5 is provided on the upper surface of the slider 4. The slider 4 is slidably connected to the surface of the round rod 5 through the circular hole. Two springs 6 are sleeved on the surface of the round rod 5. The opposite ends of the two springs 6 are respectively lapped with the upper and lower surfaces of the slider 4. The opposite ends of the two springs 6 are respectively lapped with the inner top wall and the inner bottom wall of the chute. After the quartz raw materials fall, they contact the sieve plate 7 and generate a certain impact force on the sieve plate 7. At this time, the sieve plate 7 can drive the slider 4 to move downward on the surface of the round rod 5, and at the same time squeeze the lower spring 6. At this time, the spring 6 can generate a reaction force to offset the impact force, thereby providing a certain buffering effect and preventing the sieve plate 7 from being damaged due to long-term exposure to a large impact force.

[0029] Working principle: First, pour the quartz raw materials into the vertical frame 2 through the feed hopper 3. The quartz raw materials first contact the sieve plate 7. Since the quartz raw materials have a certain impact force when they fall, the sieve plate 7 will drive the slider 4 to slide downward on the surface of the round rod 5 and squeeze the lower spring 6. After being squeezed, the spring 6 generates a reaction force, which can offset part of the downward impact force, thereby providing a certain buffering effect to ensure that the sieve plate 7 will not be damaged due to long-term exposure to a large impact force, extending the service life of the sieve plate 7. At the same time, the sieve plate 7 can screen quartz raw materials of different sizes. The smaller quartz raw materials fall through the sieve holes to the right side of the partition frame 9 and are directly blocked by the baffle 8 and the triangular guide plate 10 and fall onto the blanking plate 18 in the blanking chute. At this time, the hydraulic push rod 12 can drive the pressing plate 13 to descend to crush the smaller quartz raw materials. At the same time, the larger quartz raw materials fall onto the left side of the partition frame 9 through the inclined sieve plate 7. The driving motor 14 drives the two crushing rollers 16 to rotate through the two transmission shafts 15, thereby crushing the larger quartz raw materials, ensuring that quartz raw materials of different sizes can be completely crushed without any crushing dead corners.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
