Description

Technical Field

[0001] This utility model relates to the field of fluorite powder production technology, and in particular to a quantitative feeding device for fluorite powder production. Background Technology

[0002] Fluorite powder, also known as phosphor, is a powder material used in whitening, fluorescence, and radiation applications. It has high chemical stability and is widely used as an additive in chemical materials. Fluorite powder is a new type of electric light source material and can be directly used as a phosphor material for fluorescent screens, fluorescent lamps, etc. It is also the main material for single crystals in optical instruments such as optical lenses and rectifiers for infrared laser systems. It can also be used to manufacture optical glass, optical fibers, enamel, medicine, and as a catalyst for dehydration and dehydrogenation reactions and a metallurgical flux.

[0003] In current fluorite powder production, fluorite is usually directly put into a crusher. If too much fluorite is put in at once, the crushing quality will be reduced. If the crushing quality is not good, it needs to be crushed again, which will greatly reduce the work efficiency.

[0004] Therefore, it is necessary to provide a quantitative feeding device for fluorite powder production to solve the above-mentioned technical problems. Utility Model Content

The first motor is placed on the first motor plate connected to the first support plate. The other end of the second rotating shaft is rotatably connected to the side of the second support plate. The bottoms of the first support plate and the second support plate are placed on the ground.

[0008] Preferably, the baffle is made of iron, and the bottom of the discharge plate on one side of the discharge hole is provided with an installation groove, and an electromagnet is installed inside the installation groove.

[0009] Preferably, the opposite sides of the first support plate and the second support plate are respectively connected to the two sides of the guide plate, the guide plate is inclined, and the height of the end of the guide plate connected to the first support plate is higher than the height of the other end of the guide plate.

[0010] Preferably, the top two ends of the guide plate are vertically connected to a first baffle and a second baffle, respectively.

[0011] Preferably, the outer surface of the feeding frame is connected to the fixed end of the pushing cylinder via a connecting frame, and the telescopic end of the pushing cylinder passes through the outer surface of the feeding frame and is connected to the side of the pushing plate.

[0012] Preferably, a pusher groove is provided on one inner side of the feeding frame, and a pusher plate is movably connected to the inner surface of the pusher groove.

[0016] Compared with related technologies, the quantitative feeding device for fluorite powder production provided by this utility model has the following advantages:

[0017] This invention feeds fluorite into a weighing box for weighing. When the weight reaches the set value, the first motor drives the first rotating shaft and the weighing box connected to the first rotating shaft to rotate, rotating the top of the weighing box downwards. Under the action of gravity, the weighed fluorite falls into the discharge plate of the feeding frame. Then, driven by a small motor, the baffle rotates, and under the action of gravity, it falls into the feeding pipe through the discharge hole, completing one feeding operation. By continuously repeating the above operation, the same weight of material can be fed into the crusher through the feeding pipe each time, preventing the crushing quality from decreasing and the work efficiency from decreasing when too much fluorite is put in at once.

[0033] refer to Figures 1 to 5This utility model provides a quantitative feeding device for fluorite powder production, comprising: a feeding pipe 2 connected to a crusher, the top of the feeding pipe 2 being movably connected to the bottom of a feeding frame 1, a discharge plate 3 installed at the lower end of the inner surface of the feeding frame 1, a plurality of discharge holes 4 provided at the top of the discharge plate 3, a baffle 13 provided inside the feeding frame 1 below the discharge plate 3, the side of the baffle 13 being connected to one end of a rotating shaft 14, the other end of the rotating shaft 14 passing through the inner surface of the feeding frame 1 and connected to the drive end of a small motor 23, the small motor 23 being mounted on a motor plate 24 connected to the outer surface of the feeding frame 1, a weighing box 8 for weighing materials being provided on one side above the feeding frame 1, and a rotating mechanism 9 for rotating the weighing box 8 being connected to the side of the weighing box 8.

[0034] In the embodiments of this utility model, reference is made to Figure 2 As shown, the rotating mechanism 9 includes a first rotating shaft 21 and a second rotating shaft 22. The two sides of the weighing box 8 are respectively connected to one end of the first rotating shaft 21 and the second rotating shaft 22. The other end of the first rotating shaft 21 passes through the side of the first support plate 16 and is connected to the drive end of the first motor 17. The first motor 17 is placed on the first motor plate 18 connected to the first support plate 16. The other end of the second rotating shaft 22 is rotatably connected to the side of the second support plate 19. The bottoms of the first support plate 16 and the second support plate 19 are placed on the ground.

[0035] It should be noted that the weighing box 8 uses an existing device with a weighing sensor. Fluorite is fed into the weighing box 8 for weighing via an existing conveying device. When the weight reaches the set value, the first motor 17 drives the first rotating shaft 21 and the weighing box 8 connected to the first rotating shaft 21 to rotate, causing the top of the weighing box 8 to rotate downwards. Under the action of gravity, the weighed fluorite falls onto the discharge plate 3 in the feed frame 1. Then, driven by the small motor 23, the baffle 13 rotates, and under the action of gravity, it falls into the feed pipe 2 through the discharge hole 4, completing one feeding operation. By continuously repeating the above operation, the same weight of material can be fed into the crusher through the feed pipe 2 each time, preventing the crushing quality from decreasing and the working efficiency from decreasing when too much fluorite is put in at once.

[0036] In the embodiments of this utility model, reference is made to Figure 5 As shown, the baffle 13 is made of iron, and the bottom of the discharge plate 3 on one side of the discharge hole 4 is provided with a mounting groove 27, and an electromagnet 28 is installed inside the mounting groove 27.

[0037] It should be noted that by setting up electromagnet 28, the stability of the baffle 13 supporting the discharge hole 4 can be improved through the magnetism of electromagnet 28.

[0038] In the embodiments of this utility model, reference is made to Figure 1 As shown, the opposite sides of the first support plate 16 and the second support plate 19 are respectively connected to the two sides of the guide plate 10. The guide plate 10 is inclined, and the height of the end of the guide plate 10 connected to the first support plate 16 is higher than the height of the other end of the guide plate 10.

[0039] In the embodiments of this utility model, reference is made to Figure 1 As shown, the top two ends of the guide plate 10 are vertically connected to the first baffle 11 and the second baffle 12, respectively.

[0040] It should be noted that by setting the inclined guide plate 10, the stability of the weighing box 8 feeding the material into the feeding frame 1 can be improved through the guidance of the guide plate 10. The first baffle 11 and the second baffle 12 can protect the edge of the guide plate 10 to prevent the material from falling during the feeding process.

[0041] In the embodiments of this utility model, reference is made to Figure 4 As shown, the outer surface of the feeding frame 1 is connected to the fixed end of the pushing cylinder 25 through the connecting frame 26, and the telescopic end of the pushing cylinder 25 passes through the outer surface of the feeding frame 1 and is connected to the side of the pushing plate 5.

[0042] In an embodiment of this utility model, a pusher groove is provided on one inner side of the feeding frame 1, and a pusher plate 5 is movably connected to the inner surface of the pusher groove.

[0043] It should be noted that after the baffle 13 is opened and the fluorite falls into the feed pipe 2 under the action of gravity, the pusher cylinder 25 is extended and retracted to drive the pusher plate 5 to move, pushing the fluorite left on the discharge plate 3 off the discharge plate 3, preventing the fluorite from accumulating on the discharge plate 3 and affecting the weight of a single feeding. In addition, a pusher groove is set to place the pusher plate 5 to prevent the material from impacting the pusher plate 5 when it enters the feed frame 1 from the weighing box 8, which would affect the subsequent use of the pusher plate 5.

[0044] In the embodiments of this utility model, reference is made to Figure 4 As shown, there are multiple pusher cylinders 25, which are linearly and equidistantly distributed on the side of the feed frame 1.

[0045] It should be noted that by setting multiple pusher cylinders 25, the force on the pusher plate 5 is evenly distributed, thereby improving the stability of the pusher plate 5 when moving left and right.

[0046] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3 As shown, the top of the feed pipe 2 is provided with multiple connecting shafts 20, and the bottom of the feed frame 1 is provided with a connecting groove 15 that cooperates with the connecting shafts 20.

[0047] It should be noted that by setting the connecting shaft 20 and the connecting groove 15, the stability of the connection between the feed pipe 2 and the feed pipe 2 is improved.

[0048] In the embodiments of this utility model, reference is made to Figure 1 As shown, the outer sides of the pushing cylinder 25 and the small motor 23 are respectively provided with cylinder protection box 7 and motor protection box 6, and the opening ends of the cylinder protection box 7 and motor protection box 6 are respectively connected to the two outer surfaces of the feeding frame 1.

[0049] It should be noted that the cylinder protection box 7 and the motor protection box 6 are used to protect the pusher cylinder 25 and the small motor 23.

[0050] The working principle of the quantitative feeding device for fluorite powder production provided by this utility model is as follows:

[0051] Fluorite is fed into the weighing box 8 using the existing conveying device. When the weight reaches the set value, the first motor 17 drives the first rotating shaft 21 and the weighing box 8 connected to the first rotating shaft 21 to rotate, causing the top of the weighing box 8 to rotate downwards. Under the action of gravity, the weighed fluorite falls onto the discharge plate 3 in the feed frame 1. Then, driven by the small motor 23, the baffle 13 rotates, and under the action of gravity, it falls into the feed pipe 2 through the discharge hole 4, completing one feeding operation. By continuously repeating the above operation, the same weight of material can be fed into the crusher through the feed pipe 2 each time, preventing the crushing quality from decreasing and the working efficiency from decreasing when too much fluorite is put in at once.

[0052] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
