Technical Field

[0001] This utility model relates to the field of fluorite ore screening technology, specifically a screening device for fluorite ore processing. Background Technology

[0002] Fluorite, also known as fluorspar, belongs to the isometric crystal system and crystals in octahedral and cubic forms. Its main component is calcium fluoride (CaF2). Crystals exhibit a vitreous luster. Pure fluorite is colorless, but common colors range from light green to dark green, blue, bluish-green, yellow, wine yellow, purple, violet, gray, brown, rose red, and deep red. It is brittle, with a Mohs hardness of 4 and a melting point of 1360℃, and exhibits perfect cleavage. Some samples can luminescent under friction, heating, or ultraviolet radiation. Fluorite is a relatively common mineral in nature, often occurring alongside many other minerals. It is found in many parts of the world and has five valid varieties.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-6 A screening device for fluorite ore processing is shown, including a screening box 1. A feed inlet 2 is provided on one side of the top of the screening box 1. Multiple sets of first discharge outlets 3 are sequentially provided from top to bottom on the side wall of the screening box 1 away from the feed inlet 2. A screening plate 4 is provided in the first discharge outlet 3. A limiting groove 5 is provided in the first discharge outlet 3. A rotating shaft 6 is fixed on the outside of the screening plate 4. The rotating shaft 6 is movably disposed in the limiting groove 5. A limiting seat 7 is installed on the outside of the screening box 1. The limiting seat 7 extends into the first discharge outlet 3 and is movably fitted with the screening plate 4. A support frame 8 is provided on the side of the inner cavity of the screening box 1 away from the first discharge outlet 3. A support block 9 is fixed on the support frame 8. A groove 10 is provided on the side of the screening plate 4 to cooperate with the support frame 8. A drive assembly 11 for vibrating the support frame 8 is provided at the bottom of the screening box 1.

[0028] It also includes a conveyor frame 12 located on top of and inside the screening box 1 for conveying stones;

[0029] A control box is installed on the outside of the screening box 1;

[0030] By movably setting the screening plate 4 inside the screening box 1, one end of the screening plate 4 is movably set inside the first discharge port 3 via the rotating shaft 6, and the other end is movably snapped onto the support frame 8 via the groove 10. Both are connection methods that are easy to disassemble and assemble. Simply remove the limiting seat 7 from the first discharge port 3 to move the screening plate 4 out of the screening box 1 from the first discharge port 3. The operation is simple, the workload is low, and it is easy to make quick replacements.

[0031] The drive motor 113 has a power of 1.5kw and an adjustable vibration frequency range of 10-50Hz. The control box adopts a PLC control system, which can adjust the vibration frequency and cleaning cycle according to the characteristics of the ore.

[0032] Among them, such as Figure 2 and Figure 6 As shown:

[0033] The outer side of the limiting seat 7 is provided with mounting bolts 13. The mounting bolts 13 pass through the limiting seat 7 and are threadedly connected to the screening box 1. With the cooperation of the mounting bolts 13, the limiting seat 7 can be easily fixed and also easily removed.

[0034] Furthermore, such as Figure 3-4 As shown:

[0035] The drive assembly 11 includes a connecting rod 111 fixed to the bottom of the support frame 8. The bottom of the connecting rod 111 passes through the screening box 1 and is fixed to a support plate 112. A drive motor 113 is fixed to the bottom of the screening box 1. A cam 114 is fixed to the output shaft of the drive motor 113. The cam 114 is attached to the bottom of the support plate 112. The drive motor 113 drives the cam 114 to rotate. Subsequently, the cam 114 indirectly drives the support plate 112 to move up and down. At the same time, the support plate 112 drives the support frame 8 to move up and down through the connecting rod 111, so that the support frame 8 has an up and down vibration effect, which facilitates the up and down shaking of the screening plate 4, which facilitates the screening of fluorite ore and also helps the ore to slide on the screening plate 4.

[0036] Preferred, such as Figure 5 As shown:

[0037] The conveyor frame 12 includes a fixed frame 121. Two sets of support rollers 122 are rotatably connected to the inner cavity of the fixed frame 121 via bearings. A conveyor belt 123 is driven to the outer side of the support rollers 122. A rotary motor 124 is fixed to the outer side of the fixed frame 121. The output shaft of the rotary motor 124 is fixedly connected to one end of a set of support rollers 122. The rotary motor 124 serves as the drive source to drive the support rollers 122 to rotate, and the conveyor belt 123 is used to transport the ore.

[0038] It is worth noting that, such as Figure 1-3 As shown:

[0039] A second discharge port 14 is provided at the lower end of the side wall of the screening box 1. An inclined block 15 is fixed at the bottom of the inner cavity of the screening box 1. The inclined block 15 facilitates the collection of the fine ore that finally falls to the bottom of the inner cavity of the screening box 1 and removes it from the screening box 1 through the second discharge port 14.

[0040] In a further preferred embodiment, such as Figure 3 As shown:

[0041] Multiple sets of arc-shaped grooves 16 are provided on the side of the inner cavity of the screening box 1 away from the first discharge port 3. The screening plate 4 is slidably disposed in the arc-shaped grooves 16. The arc-shaped grooves 16 facilitate the limiting of the screening plate 4, ensuring that the screening plate 4 works stably in the screening box 1, and at the same time provide convenience for the disassembly and assembly of the screening plate 4.

[0042] In addition, such as Figure 4 As shown:

[0043] A support spring 17 is fixed to the top of the support plate 112. The top of the support spring 17 is fixed to the bottom of the screening box 1. The support spring 17 facilitates the support of the support plate 112 and increases the vibration frequency of the support plate 112.

[0044] In this embodiment, as Figure 3As shown:

[0045] The screening holes on the multiple screening plates 4 have different diameters, and the screening plates 4 are arranged from top to bottom in order of decreasing diameter. By limiting the size of the holes on the screening plates 4, the ore is screened in sequence, and fluorite ore particles of different sizes are screened out from the first discharge port 3 and the second discharge port 14.

[0046] In practical use, when the screening plate 4 needs to be replaced, the mounting bolts 13 are removed using tools. Then, the limiting seat 7 is moved out of the first discharge port 3, and the screening plate 4 is moved outward from the first discharge port 3. The rotating shaft 6 moves outward within the limiting groove 5, and the other end of the screening plate 4 separates from the support frame 8. After quickly replacing the screening plate 4, the limiting seat 7 is reinstalled in the first discharge port 3 and secured with the mounting bolts 13. The drive motor 113 is then started, causing the cam 114 to rotate. The cam 114 contacts the support plate 112, causing the support plate 112 to move up and down. The support plate 112 drives the support frame 8 to move up and down through the connecting rod 111, synchronously driving the rotary motor 124. The rotary motor 124 drives the support roller 122 to rotate, and the conveyor belt 123 drives the ore to move. The fluorite ore to be screened enters the screening box 1 from the feed port 2 and falls onto the top screening plate 4. One end of the screening plate 4 begins to vibrate as the support frame 8 moves up and down, causing some ore to fall through the screening plate 4. The ore that does not fall is moved out of the screening box 1 from the first discharge port 3. The falling ore is transported by the conveyor belt 123 to the screening plate 4 below for repeated screening.

[0047] 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, the scope of which is defined by the appended claims and their equivalents.
