Description

Technical Field

[0001] This invention relates to the field of ore transportation technology, and in particular to a raw material conveying device for barite preparation with impurity removal function. Background Technology

[0002] Barite is the most common barium mineral, and its composition is barium sulfate. It occurs in low-temperature hydrothermal veins, such as quartz-barite veins and fluorite-barite veins, often associated with galena, sphalerite, chalcopyrite, and cinnabar. Barite deposits are mostly large hydrothermal monomineralic veins. Barite can also occur in sedimentary rocks as nodules, primarily in sedimentary manganese deposits and shallow marine argillaceous and sandy sedimentary rocks. In the residual clay overburden of weathered residual deposits, it often forms nodules or massive forms.

[0003] Current barite processing typically involves the following steps: crushing the raw barite ore, screening it, washing the qualified barite particles, drying the cleaned particles, and finally grinding them to prepare powder. In the barite screening process, existing screening devices often require a large flow of water, utilizing the water drop for screening. This results in high water consumption and costs. Furthermore, the screening devices are usually inconvenient to transport, requiring the use of other tools to remove them, leading to low utilization rates and high costs. Summary of the Invention

[0004] The purpose of this invention is to provide a raw material conveying device for barite preparation with impurity removal function, so as to solve the problems mentioned in the background art. Existing screening devices often require a large amount of water flow and use the water flow drop to screen barite, which consumes a large amount of water resources and has a high cost. Moreover, the screening device is usually inconvenient to transport and needs to be transported out with the help of other tools, resulting in low utilization rate and high cost of the screening device.

[0017] In this invention, by setting a transmission mechanism on the motor, the device can transport the raw materials after impurity removal and filtration at the same time, which greatly improves the working efficiency. Furthermore, the use of the same motor for raw material filtration and transportation reduces production costs. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Reference Figures 1-7A raw material conveying device for barite preparation with impurity removal function includes a first protective plate 1 and a second protective plate 2. A motor 18 is installed on the outer wall of the second protective plate 2. A first filter tank 8 and a second filter tank 9 are slidably installed between the first protective plate 1 and the second protective plate 2. A conveyor belt 21 is arranged below the second filter tank 9. A first transmission roller 22 and a second transmission roller 23 are respectively arranged inside the two ends of the conveyor belt 21. A first gear rack 11 and a second gear rack 12 are respectively installed on the side of the first filter tank 8 and the second filter tank 9 away from the first protective plate 1. A gear 13 is rotatably mounted in the middle. A track 15 is mounted on the side of the first gear rack 11 away from the first filter tank 8. A fixing block 17 is set inside the track 15. An eccentric shaft 14 is connected to one end of the fixing block 17 near the second protective plate 2. A first transmission wheel 26 is set on the side of the eccentric shaft 14 near the second protective plate 2. The end of the eccentric shaft 14 away from the gear 13 and the first transmission wheel 26 are both rotatably mounted on the output shaft of the motor 18. A belt 28 is rotatably mounted on the first transmission wheel 26. A second transmission wheel 27 is mounted on the other end of the belt 28. The second transmission wheel 27 is connected to the first transmission roller 22.

[0029] When the raw materials for barite preparation need to be purified, the motor 18 is operated, causing the eccentric shaft 14 mounted on the output shaft of the motor 18 to rotate synchronously. The rotation of the eccentric shaft 14 drives the track 15 to start reciprocating, thereby causing the first gear rack 11 connected to the track 15 to move. The first gear rack 11 drives the gear 13 to move, and the gear 13 drives the second gear rack 12 to move. This causes the first filter tank 8 and the second filter tank 9 to continuously approach and then move away, realizing the reciprocating motion between the first filter tank 8 and the second filter tank 9. This allows the raw materials for barite preparation filtered out by the first filter tank 8 to fall onto the second filter tank 9, and then undergo further filtration through the second filter tank 9.

[0030] When the raw materials for barite preparation need to be purified, the motor 18 is operated, causing the first transmission wheel 26 mounted on the output shaft of the motor 18 to rotate. The rotation of the first transmission wheel 26 causes the belt 28 on the first transmission wheel 26 to rotate, which in turn drives the second transmission wheel 27 to rotate. The second transmission wheel 27 then drives the first transmission roller 22 to rotate, causing the conveyor belt 21 rotatably connected to the first transmission roller 22 to rotate, thereby driving the second transmission roller 23 to move, realizing the operation of the entire conveyor belt 21. The raw materials for barite preparation after purification fall onto the conveyor belt 21 and are transported by the operation of the conveyor belt 21.

[0031] Reference Figures 1-2In this embodiment, the first protective plate 1 and the second protective plate 2 are respectively provided with a first sliding groove 3 and a second sliding groove 4. The ends of the first sliding groove 3 and the second sliding groove 4 that are far apart from each other are inclined downward. Two connecting posts 5 are respectively installed on both sides of the first filter groove 8 and the second filter groove 9. The connecting posts 5 are adapted to the first sliding groove 3 and the second sliding groove 4, so that the first filter groove 8 and the second filter groove 9 can move on the first protective plate 1 and the second protective plate 2 through the connecting posts 5. When the connecting posts 5 pass through the inclined downward part of the groove opening of the first sliding groove 3 and the second sliding groove 4, the first filter groove 8 and the second filter groove 9 vibrate, which speeds up the filtration speed. When the connecting posts 5 slide to the lowest end of the groove, the first filter groove 8 and the second filter groove 9 are inclined downward, and impurities that cannot be filtered by the first filter groove 8 and the second filter groove 9 are discharged from the first filter groove 8 and the second filter groove 9.

[0032] Reference Figures 1-2 In this embodiment, a first spring 6 is connected to the wall surface at the lowest end of the first slide 3 and the second slide 4. The other end of the first spring 6 is connected to a shock absorber 7. The shock absorber 7 is adapted to the first slide 3 and the second slide 4, so that the speed of the connecting column 5 is slowed down when it slides to the lowest end of the first slide 3 and the second slide 4. It will not crash violently into the wall surface of the first slide 3 and the second slide 4 due to the gravity of the raw materials for barite preparation placed on the first filter tank 8 and the second filter tank 9, thereby reducing the wear of the device and improving its service life.

[0033] Reference Figure 4 In this embodiment, the first gear rack 11 and the second gear rack 12 are symmetrical to each other, and the teeth of the first gear rack 11, the second gear rack 12 and the gear 13 mesh with each other, so that when the gear 13 rotates, it can drive the first gear rack 11 and the second gear rack 12 to run synchronously.

[0034] Reference Figure 2 In this embodiment, the bottom of the first filter tank 8 is provided with several larger holes, and the bottom of the second filter tank 9 is provided with several smaller holes. Baffles 10 are provided on the sides of the first filter tank 8 and the second filter tank 9 that are far apart from each other. When the workers load materials, the raw materials for barite preparation are filtered through the holes provided on the first filter tank 8 to the second filter tank 9, and then further filtered and screened through the smaller holes on the second filter tank 9. Due to the baffles 10, the raw materials for barite preparation placed on the first filter tank 8 and the second filter tank 9 are blocked by the baffles 10 and are not easy to fall from the first filter tank 8 to the ground. Also, since the first filter tank 8 and the second filter tank 9 are only provided with baffles 10 at one end and the other end is open, impurities can be discharged from the open end.

[0035] Reference Figures 2-3In this embodiment, both the first transmission wheel 26 and the second transmission wheel 27 are provided with transmission grooves 29. The transmission grooves 29 are adapted to the belt 28, making it difficult for the belt 28 to fall off the first transmission wheel 26 and the second transmission wheel 27, thus ensuring the smooth transmission of power.

[0036] Reference Figures 5-6 In this embodiment, a first connecting shaft 16 is installed at one end of the eccentric shaft 14 away from the input end of the motor 18, and the other end of the first connecting shaft 16 extends into the track 15. When the eccentric shaft 14 rotates, the track 15 can be driven to rotate synchronously through the first connecting shaft 16.

[0037] Reference Figures 3-4 In this embodiment, a drive shaft 24 is provided at the center of the first drive roller 22, and a second connecting shaft 25 is connected to the center of the second drive roller 23. One end of the drive shaft 24 is rotatably connected to the inner wall of the first protective plate 1, and the other end passes through the second protective plate 2 and is connected to the second drive wheel 27. The two ends of the second connecting shaft 25 are rotatably connected to the inner walls of the first protective plate 1 and the second protective plate 2, respectively. When the second drive wheel 27 rotates, it drives the drive shaft 24 to rotate, so that the first drive roller 22 rotates synchronously, providing power output for the operation of the conveyor belt 21.

[0038] Reference Figure 2 In this embodiment, four support columns 20 are provided around the first transmission wheel 26. One end of each of the four support columns 20 is connected to the second protective plate 2, and the other end is connected to a support plate 19. The motor 18 is mounted on the support plate 19. The support plate 19 is configured to provide a support base for the motor 18 and improve the stability of the motor 18.

[0039] Reference Figure 7 In this embodiment, several connecting blocks 30 are installed at the bottom of the first protective plate 1 and the second protective plate 2. A first spring pad 33 and a second spring pad 34 are provided below the connecting blocks 30. A second spring 32 is provided between the first spring pad 33 and the second spring pad 34. A base 35 is connected below the second spring pad 34. A threaded rod 31 is threadedly installed at the center of the connecting block 30. The threaded rod 31 passes through the first spring pad 33 and the second spring 32 and contacts the second spring pad 34. An upper housing 36 is installed on the threaded rod 31. A lower housing 37 is installed above the base 35. The bottom of the upper housing 36 is fitted inside the lower housing 37. When the worker loads materials or the device is running, the combined action of the threaded rod 31, the second spring 32, the upper housing 36 and the lower housing 37 causes gravity to act downwards in the vertical direction, thereby reducing vibration and stabilizing the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
