Description

Technical Field

[0001] This utility model relates to the field of flotation machines, and in particular to a fluorite flotation machine for removing impurities. Background Technology

[0002] Fluorite flotation machines are widely used in mining and mineral processing, primarily for separating and extracting fluorite from other metallic and non-metallic minerals. The working principle of a fluorite flotation machine is based on the differences in mineral surface properties. During flotation, the wettability of the mineral surface is altered by adjusting the pH of the pulp and adding specific flotation reagents (such as collectors and depressants). Subsequently, a motor-driven impeller rotates, generating centrifugal force to create negative pressure, drawing in sufficient air to mix with the pulp. Simultaneously, a stirring device agitates the pulp and reagents, refining the foam so that fluorite particles can adhere to the bubbles. Due to buoyancy, these bubbles rise to the surface, forming a concentrate foam layer, while gangue minerals remain in the flotation cell. Finally, the liquid level is controlled by adjusting the gate height, allowing the useful foam to be scraped off by a scraper, thus achieving the separation of ore and impurities.

[0003] In actual use of fluorite flotation machines, frequent collisions occur between the material and the internal isolation hood when the fan blades accelerate the material's rotation. This prolonged physical impact can easily damage the isolation hood, increasing maintenance costs and potentially leading to more serious mechanical failures.

[0004] Furthermore, due to this continuous impact and wear, impurities easily accumulate inside the flotation machine. If these impurities are not removed in time, they will seriously affect the efficiency of the flotation machine. They may interfere with mineral separation during the flotation process, leading to a decrease in recovery rate and concentrate grade. At the same time, the presence of impurities may also accelerate equipment wear, further shortening the service life of the equipment. Utility Model Content

[0005] The main objective of this invention is to provide a fluorite flotation machine for removing impurities, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fluorite flotation machine for removing impurities includes a casing, a partition plate, a flotation chamber, a fixed base, a drive unit, a connecting sleeve, and a fan blade assembly. The upper end of the casing has a flotation chamber, the partition plate is located in the middle of the flotation chamber, the fixed base is mounted on the casing, the drive unit is located on the side wall of the fixed base and fixed to the casing, the connecting sleeve is located at the lower end of the fixed base, and the fan blade assembly is mounted at the lower end of the connecting sleeve. The drive unit drives the fan blade assembly to rotate, thereby accelerating the movement of materials in the flotation chamber.

[0008] The isolation plate and the flotation chamber walls are both equipped with protective isolation covers, and the interior of the protective isolation cover is provided with an inner protruding strip. The side wall of the inner protruding strip is provided with a first slot, and the notch of the protective isolation cover is provided with a second slot. U-shaped protective plates are inserted and connected to the first slot and the second slot. The U-shaped protective plates are used to protect the internal materials from rotation and collision. The insertion of the U-shaped protective plates allows for quick replacement.

[0009] A filter screen is installed on the upper part of the outer end of the U-shaped protective plate to filter impurities in the flotation chamber. A discharge hood is provided at the lower end of the U-shaped protective plate, and a discharge pipe is installed at the lower end of the chassis. The discharge hood is directly opposite the discharge pipe, and impurities are discharged through the discharge hood and the discharge pipe.

[0010] As a preferred embodiment of this utility model, the protective isolation cover has an "Ω" shaped cross-section, and multiple mounting holes are provided on the edge of the end face of the protective isolation cover. Bolts are inserted into the mounting holes to fix the protective isolation cover to the chassis and the isolation plate.

[0011] As a preferred embodiment of this utility model, the inner protruding strip and the protective isolation cover are designed as an integral part, and the inner protruding strip is located in the middle of the protective isolation cover, and the width of the notch of the inner protruding strip is consistent with the width of the notch of the protective isolation cover.

[0012] As a preferred embodiment of this utility model, the side section of the U-shaped protective insert has an inverted "U" shape design. The U-shaped protective insert is located at the lower end of the discharge hood. The U-shaped protective insert and the discharge hood are designed as an integral unit, and the lower corner of the discharge hood has an arc-shaped design.

[0013] As a preferred embodiment of this utility model, the U-shaped protective insert plate is adapted to the first slot and the second slot, and the edge of the U-shaped protective insert plate is bonded with an anti-slip rubber strip. The U-shaped protective insert plate, the inner convex strip and the protective isolation cover are all made of protective material.

[0014] As a preferred embodiment of this utility model, the filter screen is integrally designed with the U-shaped protective insert plate welded on it. The filter screen is a double-layer filter screen, and a support frame is provided inside the double-layer filter screen.

[0015] As a preferred embodiment of this utility model, the discharge pipe and the casing are designed as an integrated unit, and a valve is installed on the discharge pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The protective enclosure design significantly enhances the structural stability and protective effect of the flotation machine. Its Ω-shaped cross-section design not only improves the structural strength but also effectively disperses and absorbs the impact force generated during material collisions, thereby protecting the internal structure of the flotation machine and extending the service life of the equipment.

[0018] The U-shaped protective insert plate, with its inverted "U" shape and slot-fitting design with the protective isolation cover, allows for quick replacement. Meanwhile, the anti-slip rubber strips on the U-shaped protective insert plate increase friction between the plate and the slot, preventing displacement during high-speed rotation and ensuring the stability and safety of the flotation process.

[0019] The double-layer filter design of the filter screen effectively filters out impurities of different sizes, ensuring the purity of the flotation process. This design not only improves filtration efficiency but also increases the filtration area, making the flotation process more efficient and controllable.

[0020] The design of the discharge mechanism allows impurities to pass smoothly through the U-shaped protective baffle, discharge hood, and discharge pipe, ensuring a clean and efficient flotation process. Meanwhile, the valve design on the discharge pipe allows for precise control of the discharge flow rate and speed, further improving the accuracy and controllability of the flotation process.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4As shown, a fluorite flotation machine for impurity removal includes a casing 1, a partition plate 2, a flotation chamber 3, a fixed base 4, a drive unit 5, a connecting sleeve 6, and a fan blade assembly 7. The flotation chamber 3 is located at the upper end of the casing 1. The partition plate 2 is located in the middle of the flotation chamber 3, dividing it into two independent areas to optimize the flotation process. The fixed base 4 is mounted on the casing 1, and the drive unit 5 is fixed to the side wall of the fixed base 4 and firmly connected to the casing 1 to ensure stable operation. The connecting sleeve 6 is located at the lower end of the fixed base 4, and the fan blade assembly 7 is mounted at the lower end of the connecting sleeve 6. The drive unit 5 drives the fan blade assembly 7 to rotate, thereby accelerating the movement of materials within the flotation chamber 3 and improving flotation efficiency.

[0028] To further protect the internal structure of the flotation machine and extend its service life, both the partition plate 2 and the walls of the flotation chamber 3 are equipped with protective partition covers 8. The protective partition cover 8 has an internal protruding strip 10, a first slot 11 on its side wall, and a second slot 12 at the notch of the protective partition cover 8. The first slot 11 and the second slot 12 are connected by a U-shaped protective insert 13, achieving protection against rotational collisions of the internal materials. Simultaneously, the plug-in design of the U-shaped protective insert 13 facilitates quick replacement, which is beneficial for maintenance and repair.

[0029] To ensure effective filtration of impurities during flotation, a filter screen 14 is installed on the upper outer end of the U-shaped protective insert 13 to filter impurities within the flotation chamber 3. A discharge hood 15 is located at the lower end of the U-shaped protective insert 13, while a discharge pipe 16 is installed at the lower end of the chassis 1. The discharge hood 15 faces the discharge pipe 16, and impurities are discharged through both the discharge hood 15 and the discharge pipe 16, ensuring a clean and efficient flotation process.

[0030] The protective isolation cover 8 is designed with structural stability and protective effect in mind, and its cross-section is Ω-shaped. This design not only enhances the strength of the structure, but also helps to disperse and absorb the impact force generated when materials collide. The end face edge of the protective isolation cover 8 has multiple mounting holes 9, which are used to fix it to the casing 1 and the isolation plate 2 by inserting bolts, thereby ensuring the stability and reliability of the entire flotation machine.

[0031] The inner convex strip 10 and the protective shield 8 are designed as a single unit. The inner convex strip 10 is located in the middle of the protective shield 8, and its design purpose is to further enhance the protective effect. At the same time, the width of the notch of the inner convex strip 10 is consistent with the width of the notch of the protective shield 8, ensuring the integrity of the protective shield 8 and the consistency of the protective effect.

[0032] The U-shaped protective baffle 13 has an inverted "U" shape in its side cross-section. This design is not only aesthetically pleasing but also effectively guides the flow direction of materials, reducing the impact of materials on the interior of the flotation machine. The U-shaped protective baffle 13 is located at the lower end of the discharge hood 15 and is integrated with the discharge hood 15. The lower corner of the discharge hood 15 has an arc-shaped design, which helps to reduce turbulence generated during material flow and improves the smoothness of discharge.

[0033] The U-shaped protective insert 13 is adapted to the first slot 11 and the second slot 12, ensuring stable installation of the protective insert. Anti-slip rubber strips are bonded to the edges of the U-shaped protective insert 13, increasing the friction between the insert and the slot and preventing displacement during high-speed rotation. The U-shaped protective insert 13, the inner convex strip 10, and the protective isolation cover 8 are all made of protective materials with good wear resistance and corrosion resistance, capable of withstanding the wear and chemical corrosion of materials during flotation.

[0034] The filter screen 14 and the U-shaped protective insert 13 are welded together as a single unit. The filter screen 14 is a double-layer filter with an internal support frame. This design effectively filters out impurities of different sizes, ensuring the purity of the flotation process. The double-layer filter design also increases the filtration area and improves filtration efficiency.

[0035] The discharge pipe 16 and the casing 1 are integrated into one unit, making the entire flotation machine more compact and reducing the complexity of assembly and maintenance. Valves are installed on the discharge pipe 16; by adjusting the opening and closing of these valves, the flow rate and speed of the discharge can be controlled, making the flotation process more precise and controllable.

[0036] Check that the mounting holes 9 on the end face edge of the protective isolation cover 8 are securely fixed to the chassis 1 and the isolation plate 2 with bolts. Confirm that the side profile of the U-shaped protective insert 13 has an inverted "U" shape and check its compatibility with the first slot 11 and the second slot 12. Check that the edges of the U-shaped protective insert 13 are bonded with anti-slip rubber strips to ensure increased friction and prevent displacement. At the same time, confirm that the filter screen 14 is securely welded to the U-shaped protective insert 13 and check that its double-layer filter design is intact. Check that the discharge pipe 16 is integrated with the chassis 1 and confirm that the valve is installed and adjustable. Place the fluorite material to be floated into the flotation chamber 3. Start the drive unit 5 to rotate the fan blade assembly 7 to accelerate the movement of the material in the flotation chamber 3.

[0037] During the flotation process, the materials are thoroughly mixed and collided under the drive of the fan blade assembly 7. The partition plate 2 divides the flotation chamber 3 into two independent areas, thereby optimizing the flotation process. The U-shaped protective baffle 13 guides the flow direction of the materials and reduces the impact on the inside of the flotation machine. The filter screen 14, through its double-layer filter design, filters out impurities of different sizes, ensuring the purity of the flotation process.

[0038] Impurities are discharged through the U-shaped protective baffle 13, discharge hood 15, and discharge pipe 16. The flow rate and speed of the discharge can be controlled by adjusting the valves on the discharge pipe 16, ensuring the accuracy and controllability of the flotation process. If the U-shaped protective baffle 13 or other components need to be replaced, they can be quickly pulled out and replaced, making equipment maintenance and repair more convenient. After the flotation process is complete, the drive unit 5 is turned off, and the rotation of the fan blade assembly 7 is stopped. Residual material in the flotation chamber 3 and discharge pipe 16 is cleaned. The wear condition of each component of the flotation machine is checked regularly to ensure continuous normal operation. Wear-prone components such as the protective isolation hood 8 and the U-shaped protective baffle 13 are replaced or repaired to extend the service life of the equipment.

[0039] This utility model is not limited to the above-described embodiments. For those skilled in the art, various improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model. Contents not described in detail in this specification are prior art known to those skilled in the art.
