Description

Technical Field

[0001] This utility model belongs to the field of sorting technology, specifically relating to a vanadium-titanium pellet sorting device with multi-stage screening function. Background Technology

[0002] Vanadium-titanium magnetite green pellet size sorting refers to the process of classifying the green pellets (unroasted pellets) by particle size during the production of vanadium-titanium magnetite pellets. This process aims to ensure that the particle size distribution of the pellets meets the requirements of subsequent roasting and smelting, thereby improving the quality of the pellets and smelting efficiency. The main steps of vanadium-titanium magnetite green pellet size sorting are as follows: Green pellet preparation: After mixing vanadium-titanium magnetite powder with a binder, green pellets are made by a pelletizing machine (such as a disc pelletizing machine or a cylindrical pelletizing machine). The particle size of green pellets is usually between 8-16 mm, but there will be a certain range of particle size distribution in actual production. Screening: After the green pellets are prepared, they need to be sorted by particle size using screening equipment. Screening equipment is usually equipped with multiple layers of screens to separate the green pellets into different particle size ranges, such as: oversized pellets (>16 mm); qualified pellets (8-16 mm); and undersized pellets (<8 mm).

[0003] In the screening of vanadium-titanium pellets, it is necessary to distinguish between oversized pellets, qualified pellets, and undersized pellets. When using a screen for sorting, the pellets can get stuck in the mesh of the screen, preventing them from passing through and affecting the sorting efficiency. Furthermore, when the pellets fall between multiple screens, they collide with the screens, causing them to break. Based on this, a vanadium-titanium pellet sorting device with multi-stage screening function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a vanadium-titanium pellet sorting device with a simple structure and reasonable design and multi-stage screening function in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A vanadium-titanium pellet sorting device with multi-stage screening function includes a screening box. A feed hopper is fixedly connected to the top of the screening box. A door is installed at the front of the screening box. Multiple first sorting rollers arranged in an inclined array at equal intervals are installed inside the screening box. A first discharge hopper is installed on one side of the screening box and is located at the lower end of the multiple first sorting rollers. Multiple second sorting rollers arranged in an inclined array at equal intervals are installed inside the screening box. A second discharge hopper is installed on the other side of the screening box and is located at the lower end of the second sorting rollers. The spacing between the first sorting rollers is twice the spacing between the second sorting rollers. The first sorting rollers are located above the second sorting rollers. A screening mechanism is installed inside the screening box.

[0007] As a further optimization of this utility model, a first motor is installed on the outer surface of the screening box, a first reciprocating screw is fixedly connected to the output end of the first motor, a first slider is threadedly connected to the outer surface of the first reciprocating screw, a first connecting plate is fixedly connected to the bottom of the first slider, and a first lever is fixedly connected to the top of the first connecting plate.

[0008] As a further optimization of this utility model, a first groove is provided at the bottom of the first sorting roller located in the middle, the first slider is slidably connected to the first groove, the first lever is arranged between adjacent first sorting rollers, and the first reciprocating screw passes through the screening box and is rotatably connected to the screening box.

[0009] As a further optimization of this utility model, a second motor is installed on the outer surface of the screening box, a second reciprocating screw is fixedly connected to the output end of the second motor, a second slider is threadedly connected to the outer surface of the second reciprocating screw, a second connecting plate is fixedly connected to the bottom of the second slider, and a second lever is fixedly connected to the top of the second connecting plate.

[0010] As a further optimization of this utility model, a second groove is provided at the bottom of the second sorting roller located in the middle, the second slider is slidably connected to the second groove, the second lever is arranged between adjacent second sorting rollers, and the second reciprocating screw passes through the screening box and is rotatably connected to the screening box.

[0011] As a further optimization of this utility model, the screening mechanism includes a fixed plate fixedly connected inside the screening box, a damping rod fixedly connected to the top of the fixed plate, a connecting spring sleeved on the outer surface of the damping rod, a filter screen fixedly connected to the top of the damping rod, the filter screen being inclined and fitting against the inner surface of the screening box, the two ends of the connecting spring being fixedly connected to the filter screen and the fixed plate respectively, and a third discharge hopper installed on one side of the screening box located at the first discharge hopper, the third discharge hopper being located at the lower end of the filter screen, and the filter screen being located below the second sorting roller.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the combined use of a first lever and a second lever. When vanadium-titanium pellets are sorted by the first and second sorting rollers, the first and second motors are activated, causing the first and second reciprocating lead screws to rotate. This, in turn, drives the first and second connecting plates to move via the first and second sliders. Consequently, the first lever moves back and forth between the first and second sorting rollers, and the second lever moves back and forth between the second sorting rollers. This allows the vanadium-titanium pellets located between the sorting rollers to be moved, preventing them from getting stuck and improving sorting efficiency.

[0014] 2. This utility model utilizes the combined use of a first sorting roller and a second sorting roller made of rubber and a screening mechanism. During the screening and sorting of vanadium-titanium pellets, the impact of the vanadium-titanium pellets on the rubber sorting rollers effectively buffers the impact force. In addition, the damping rod and connecting spring installed in the screening mechanism also buffer and absorb the impact force generated by the vanadium-titanium pellets hitting the filter screen, preventing the vanadium-titanium pellets from breaking due to impact, thus providing good protection for the vanadium-titanium pellets and ensuring the quality of the sorted vanadium-titanium pellets.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a vanadium-titanium pellet sorting device with multi-stage screening function includes a screening box 1, a feed hopper 2 fixedly connected to the top of the screening box 1, a box door 6 installed at the front of the screening box 1, multiple first sorting rollers 9 arranged in an equidistant array and inclined inside the screening box 1, a first discharge hopper 3 installed on one side of the screening box 1 and located at the lower end of the multiple first sorting rollers 9, multiple second sorting rollers 16 arranged in an equidistant array and inclined inside the screening box 1, a second discharge hopper 4 installed on the other side of the screening box 1 and located at the lower end of the second sorting rollers 16, the spacing between the first sorting rollers 9 is twice the spacing between the second sorting rollers 16, and the first sorting rollers 9 are located at the lower end of the second sorting rollers 16. Above the sorting roller 16, the first sorting roller 9 and the second sorting roller 16 are made of rubber. A screening mechanism is installed inside the screening box 1. The screening mechanism includes a fixed plate 23 fixedly connected inside the screening box 1. A damping rod 21 is fixedly connected to the top of the fixed plate 23. A connecting spring 22 is sleeved on the outer surface of the damping rod 21. A filter screen 20 is fixedly connected to the top of the damping rod 21. The filter screen 20 is inclined and fits against the inner surface of the screening box 1. The two ends of the connecting spring 22 are fixedly connected to the filter screen 20 and the fixed plate 23, respectively. A third discharge hopper 5 is installed on one side of the first discharge hopper 3 in the screening box 1. The third discharge hopper 5 is located at the lower end of the filter screen 20. The filter screen 20 is located below the second sorting roller 16.

[0025] In operation, vanadium-titanium pellets to be screened are poured into the screening box 1 through the feed hopper 2. As the pellets pass through the first sorting roller 9, qualified pellets and those that are too small enter the top of the second sorting roller 16. Larger pellets are moved by the inclined first sorting roller 9 to the first discharge hopper 3 for reprocessing. Qualified pellets and those that are too small, falling onto the top of the second sorting roller 16, are further processed. The smaller pellets fall onto the top of the filter screen 20, while the qualified pellets move to the second discharge hopper 4 for further processing. When the vanadium-titanium pellets impact the filter screen 20, the damping rod 21 and connecting spring 22 buffer and absorb the impact force generated by the impact of the vanadium-titanium pellets on the filter screen 20. Some smaller powder and other impurities fall into the screening box 1 after being filtered by the filter screen 20. The oversized vanadium-titanium pellets after the powder is filtered out will be discharged through the inclined filter screen 20 to the third discharge hopper 5 for reprocessing. During this process, the first sorting roller 9 and the second sorting roller 16 made of rubber can effectively buffer the impact force generated by the vanadium-titanium pellets. The damping rod 21 and connecting spring 22 can also buffer and absorb the impact force generated by the vanadium-titanium pellets impacting the filter screen 20, avoiding the vanadium-titanium pellets from breaking due to impact, providing good protection for the vanadium-titanium pellets and ensuring the quality of the sorted vanadium-titanium pellets.

[0026] After sorting, the box door 6 can be opened to recycle the powdery material.

[0027] like Figure 3 , Figure 4 and Figure 6 As shown, a first motor 7 is installed on the outer surface of the screening box 1. A first reciprocating screw 8 is fixedly connected to the output end of the first motor 7. The first reciprocating screw 8 passes through the screening box 1 and is rotatably connected to the screening box 1. A first slider 11 is threadedly connected to the outer surface of the first reciprocating screw 8. A first connecting plate 12 is fixedly connected to the bottom of the first slider 11. A first lever 13 is fixedly connected to the top of the first connecting plate 12. The first lever 13 is arranged between adjacent first sorting rollers 9. A first groove 10 is opened at the bottom of the first sorting roller 9 located in the middle. The first slider 11 is slidably connected to the first groove 10.

[0028] When the first sorting roller 9 begins to sort vanadium-titanium pellets, the first motor 7 is started to rotate the first reciprocating screw 8. This causes the first slider 11 to slide back and forth along the inner surface of the first slide groove 10 under the rotation of the first reciprocating screw 8. This, in turn, drives the first lever 13 to move back and forth between the first sorting rollers 9 via the first connecting plate 12, thus moving the vanadium-titanium pellets located between the first sorting rollers 9 and preventing them from getting stuck between the first sorting rollers 9, thereby improving the sorting efficiency.

[0029] like Figure 3 , Figure 5 and Figure 6 As shown, a second motor 14 is installed on the outer surface of the screening box 1. A second reciprocating screw 15 is fixedly connected to the output end of the second motor 14. The second reciprocating screw 15 passes through the screening box 1 and is rotatably connected to the screening box 1. A second slider 18 is threadedly connected to the outer surface of the second reciprocating screw 15. A second connecting plate 19 is fixedly connected to the bottom of the second slider 18. A second lever 24 is fixedly connected to the top of the second connecting plate 19. The second lever 24 is arranged between adjacent second sorting rollers 16. A second groove 17 is opened at the bottom of the second sorting roller 16 located in the middle. The second slider 18 is slidably connected to the second groove 17.

[0030] When the first motor 7 is working, the second motor 14 is started synchronously, causing the second reciprocating screw 15 to rotate. This causes the second slider 18 to slide back and forth along the inner surface of the second slide groove 17 under the rotation of the second reciprocating screw 15. This, in turn, drives the second lever 24 to move back and forth between the second sorting rollers 16 via the second connecting plate 19, thus moving the vanadium-titanium balls located between the second sorting rollers 16 and preventing them from getting stuck between the second sorting rollers 16, thereby improving the sorting efficiency.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
