Description

Technical Field

[0001] This invention relates to a crusher, and more particularly to a rotary fluorite crusher. Background Technology

[0002] Fluorite, also known as fluorspar, is a relatively common mineral in nature. It can occur in association with many other minerals and is found in many parts of the world, with five effective varieties. It crystallizes in octahedral and cubic forms. The crystals have a vitreous luster, are brightly colored and varied in color, are brittle, have a Mohs hardness of 4, a melting point of 1360℃, and exhibit perfect cleavage. Some samples can fluorite under friction, heating, or ultraviolet radiation. Fluorite powder is formed by processing natural fluorite ore into fine powder through crushing, grinding, and flotation.

[0003] Existing equipment for crushing large-particle fluorite ore generally includes jaw crushers, gyratory crushers, cone crushers, and impact crushers. These crushers are generally vertical structures, requiring large-particle raw materials to be fed from the top of these crushing devices, which necessitates lifting the large-particle raw materials to a relatively high height. The crushed small-particle fluorite needs to be piled up next to the crusher or transported away by conveyor belt, occupying a large area and being difficult to store. Feeding and discharging are inconvenient, and the equipment can only be used on flat ground. It will affect the use when encountering sloping or hillside sites. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this invention discloses a rotary fluorite crusher. By excavating a kiln on a slope with a platform and digging a vertical shaft between the top of the kiln and the platform, the invention is installed on the vertical shaft. When feeding, vehicles are driven onto the platform to unload directly, unloading large fluorite particles into a hemispherical groove. The ground finished product falls directly into the kiln along the bottom of gap B, solving the problem of building a fluorite crusher on a mountainside.

[0005] To achieve the aforementioned objective, the present invention employs the following technical solution: A rotary fluorite crusher includes a grinding tank with an upper-opening hemispherical groove inside. A downwardly extending support pipe is located at the bottom of the grinding tank, and a cavity penetrating the hemispherical groove is located within the support pipe. A grinding ring is fixedly installed within the cavity. The upper half of the grinding ring has a frustoconical groove A (larger at the top and smaller at the bottom), and the lower half has a frustoconical groove B (smaller at the top and larger at the bottom) that penetrates the frustoconical groove A. A motor is located above the grinding tank, and a rotating shaft of the motor extends into the bottom of the hemispherical groove. A support mechanism is located between the motor, the rotating shaft, and the grinding tank. An elliptical frustum A (smaller at the top and larger at the bottom) is located at the lower end of the rotating shaft. An elliptical frustum B, wider at the top and narrower at the bottom, is located at the bottom of elliptical frustum B, narrower at the top and wider at the bottom. Elliptical frustum B is situated within a frustum-shaped groove A. The curved segment near the major axis of elliptical frustum B and the sidewall of frustum-shaped groove A are fitted with a clearance. A gap A is left between the curved segment near the minor axis of elliptical frustum B and the sidewall of frustum-shaped groove A. Elliptical frustum C is situated within frustum-shaped groove B. The curved segment near the major axis of elliptical frustum C and the sidewall of frustum-shaped groove B are fitted with a clearance. A gap B is left between the curved segment near the minor axis of elliptical frustum C and the sidewall of frustum-shaped groove B. Gap A and gap B are connected, and the gap gradually narrows from top to bottom from the top of gap A to the bottom of gap B.

[0006] The aforementioned rotary fluorite crusher has a support mechanism comprising two columns positioned on opposite sides of the top of the grinding tank. A collar B is fitted onto a rotating shaft located outside the grinding tank. A horizontal support rod A is positioned between the middle of the two columns, with a shaft hole B in the middle of the horizontal support rod A. A U-shaped support rod is positioned at the top of the horizontal support rod A, with a shaft hole A in the middle of the U-shaped support rod. The rotating shaft at the top of the collar B is rotatably connected to the shaft hole A, and the rotating shaft at the bottom of the collar B is rotatably connected to the shaft hole B. The middle portions of the U-shaped support rod and the middle portions of the horizontal support rod A are both clearance-fitted with the collar B.

[0007] The aforementioned rotary fluorite crusher has a horizontal support rod B between the tops of the two columns, and a collar A in the middle of the horizontal support rod B. The collar A is fitted onto the outside of the motor through its through hole.

[0008] The aforementioned rotary fluorite crusher has a support ring fitted around the outer edge of the top of the grinding tank.

[0009] The aforementioned rotary fluorite crusher has a speed reducer installed between the motor and the rotating shaft.

[0010] The aforementioned rotary fluorite crusher has a support ring sleeved on the outside of the upper end of the support pipe, and the top of the support ring is fixedly connected to the bottom of the grinding tank.

[0011] The rotary fluorite crusher has multiple grinding grooves A spaced around the side wall of the elliptical truncated cone B, multiple grinding grooves B spaced around the side wall of the elliptical truncated cone C, multiple grinding grooves C spaced around the side wall of the truncated cone-shaped trough A, and multiple grinding grooves D spaced around the side wall of the truncated cone-shaped trough B.

[0012] The rotary fluorite crusher has a perforation on the side wall of the support tube and a blind screw hole on the outer side wall of the grinding ring at a position corresponding to the perforation. After the screw passes through the perforation, it is screwed into the blind screw hole to fix the grinding ring inside the support tube.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects: The rotary fluorite crusher of this invention involves excavating a kiln on a slope with a platform, and then excavating a vertical shaft between the top of the kiln and the platform. The invention is installed on the shaft. During feeding, a vehicle is driven onto the platform to unload large fluorite particles directly into a hemispherical groove. A motor drives a rotating shaft, which in turn rotates elliptical frustums B and C. A gap A is left between the curved section near the minor axis of elliptical frustum B and the sidewall of the frustum-shaped groove A, and a gap B is left between the curved section near the minor axis of elliptical frustum C and the sidewall of the frustum-shaped groove B. Gap A and gap B are connected. The gap A gradually narrows from top to bottom to bottom of the gap B, causing large fluorite particles to be crushed to be gradually ground into smaller particles as they descend. The ground product falls directly into the kiln along the bottom of the gap B. Once a certain amount of small fluorite particles have been collected in the kiln, they can be transported to the next process. This invention solves the problem of building a fluorite crusher on a mountainside. The invention has a compact structure and is adapted to local conditions. It uses a ramp to solve the problem of building a fluorite crusher on a mountainside, which not only facilitates feeding but also solves the problem of storage after discharge, making it highly valuable for promotion.

Within body A23, the curved segment near the major axis of elliptical frustum B16 and the sidewall of frustum-shaped groove A23 are fitted with a clearance. A gap A is left between the curved segment near the minor axis of elliptical frustum B16 and the sidewall of frustum-shaped groove A23. Elliptical frustum C21 is located within frustum-shaped groove B26. The curved segment near the major axis of elliptical frustum C21 and the sidewall of frustum-shaped groove B26 are fitted with a clearance.

[0017] To implement the rotary fluorite crusher described in this invention, the motor 5 is connected to a switch and a power supply respectively, in conjunction with the attached... Figure 6 Alternatively, 7. On the slope with platform 32, dig a cave 33 into the soil layer 37 at the base surface 35. Dig a vertical shaft 38 through platform 32 upwards within the cave 33. Dig an annular groove 36 on the platform 32 at the upper edge of the vertical shaft 38. Insert the invention along the vertical shaft 38, so that the grinding pool 2 is located within the vertical shaft 38, and the support ring 1 is located within the annular groove 36. The top of the support ring 1 is flush with platform 32, and the horizontal support rod A12 is perpendicular to the slope. During feeding, drive the vehicle onto platform 32 and unload the large fluorite particles directly onto the hemispherical groove 3 from both sides. Turn on motor 5, which drives the rotating shaft 14 to rotate. The reducer 7 effectively reduces the rotational speed of the rotating shaft 14, making grinding more efficient. In a more refined manner, the rotation of the rotating shaft 14 drives the elliptical frustum B16 and elliptical frustum C21 to rotate. Since there is a gap A between the curved section near the minor axis of the elliptical frustum B16 and the side wall of the frustum-shaped groove A23, and a gap B between the curved section near the minor axis of the elliptical frustum C21 and the side wall of the frustum-shaped groove B26, gaps A and B are connected. The gap from the top of gap A to the bottom of gap B gradually narrows from top to bottom. Since there is a gap fit between the curved section near the major axis of the elliptical frustum B16 and the side wall of the frustum-shaped groove A23, the large fluorite particles located at the bottom of the hemispherical groove 3 can only enter between the curved section near the minor axis of the elliptical frustum B16 and the side wall of the frustum-shaped groove A23 along gap A. The rotation of the elliptical frustum B16 causes the large fluorite particles that enter the gap A to rotate as well. The setting of the grinding tanks A27 and C30 prevents the large fluorite particles that enter the gap A from sliding. They can only get stuck in the grinding tanks A27 and C30 and be crushed. The crushed small fluorite particles slide down the gap A. Since the gap A gradually narrows from top to bottom to the gap B, only the smaller fluorite particles can slide down by their own gravity. The slightly larger fluorite particles continue to rotate with the elliptical frustum B16 until they are squeezed into smaller pieces. After the smaller fluorite particles flow out of the gap A, they flow into the gap B left between the curved section near the minor axis of the elliptical frustum C21 and the side wall of the frustum-shaped tank B26. The rotation of the elliptical cone C21 causes the smaller fluorite particles that have entered the gap B to continue to be crushed. The setting of the grinding grooves B28 and D31 prevents the smaller fluorite particles that have entered the gap B from sliding. They can only be stuck in the grinding grooves B28 and D31 and crushed. The crushed fluorite particles slide down the gap B until they are crushed into the required particle size 34 and flow out of the gap B. The gaps A and B are set as folded surfaces so that the descent of the fluorite particles forms a maze-like descent, which slows down the descent speed and makes the grinding accuracy higher. The small fluorite particles 34 flowing out of gap B fall onto the base surface 35 inside the kiln 33. When the small fluorite particles 34 inside the kiln 33 reach a certain quantity, they can be transported to the next process. This not only facilitates feeding but also solves the problem of storing the small fluorite particles 34 after discharge, thus solving the problem of building a fluorite crusher near the mountain.

[0018] The parts of this invention not described in detail are prior art.
