[0002] Vanadium-nitrogen alloy is a new type of alloy additive, mainly used as an alloy additive for steel. It can replace ferrovanadium in the production of micro-alloyed steel. It has more effective strengthening and grain refinement effects than ferrovanadium, can effectively save vanadium addition, and reduce production costs. Under the same strength conditions, vanadium-nitrogen alloy can save 20-40% of vanadium compared with ferrovanadium, which can effectively reduce steelmaking costs.
[0003] The existing vanadium nitrogen materials have the following problems when used. First, they need to be specially crushed by equipment, and then transferred to screening equipment for screening after crushing. The crushing and screening require two types of equipment, which seriously affects the screening efficiency. Secondly, during screening, the vanadium nitrogen materials often fall to the same position of the screening net of the screening equipment. Long-term direct falling and pressure may cause local concavity and damage of the screen, affecting the subsequent screening quality. Therefore, a vanadium nitride crushing and screening device is proposed to address the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a vanadium nitride crushing and screening device to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] As an optional solution of the vanadium nitride crushing and screening device described in the utility model, wherein: a vanadium nitride crushing and screening device includes a positioning frame, a screening device and a feed hopper,
[0007] A screening device for screening vanadium nitrogen materials is installed on the inner side of the positioning frame, and the screening mesh of the screening device is arranged obliquely;
[0008] A vertically arranged feed hopper is installed on the top of the positioning frame, and a crushing mechanism for crushing the vanadium-nitrogen material is installed inside the feed hopper. A guide block is provided above the crushing mechanism, and an adjustment mechanism fixedly connected to the positioning frame is provided below the crushing mechanism.

[0012] Preferably, there are two groups of crushing rollers, and the crushing rollers are distributed on both sides of the interior of the feed hopper.
[0013] The existing vanadium-nitrogen materials have the following problems when used. First, they need equipment to be specially crushed, and then transferred to the screening equipment for screening after crushing. The crushing and screening require two types of equipment, which seriously affects the screening efficiency. Secondly, during screening, the vanadium-nitrogen materials often fall to the same position of the screening net of the screening equipment. Long-term direct falling and pressure may cause local concave damage to the screen, affecting the subsequent screening quality. When this device is in use, an external power supply is connected, and the vanadium-nitrogen material is put into the feed hopper. By starting the first motor to drive the connecting shaft to rotate, the connecting shaft drives the driving gear to rotate, thereby rotating the driven gear. At this time, the rotating shaft on one side of the driving gear and the driven gear drives the crushing rollers on the outside of the rotating shaft to rotate in opposite directions. At this time, the vanadium-nitrogen material can be effectively crushed, and the crushed material falls directly to the screening equipment below, greatly improving the screening efficiency of the vanadium-nitrogen material.
[0014] Preferably, there are two groups of guide blocks, and the outer sides of the guide blocks are fixedly connected to the feed hopper.
[0015] Preferably, the upper end surface of the guide block is arranged to be inclined, and the bottom of the guide block is arranged to be in contact with the crushing roller.
[0016] The setting of the guide blocks ensures that the material moves fully to the center of the crushing rollers on both sides, ensuring that the material is fully crushed.
[0017] Preferably, the adjustment mechanism includes a second mounting plate, a second motor and a rotating rod, the outer side of the second mounting plate is fixedly connected to the feed hopper, the second motor is fixedly connected to the top of the second mounting plate, the end of the main shaft of the second motor is fixedly connected to the rotating rod, the outer side of the rotating rod is fixedly connected to a guide plate, and both sides of the rotating rod are rotatably connected to the feed hopper.
[0018] Preferably, the vertical distance between the bottom end surface of the guide plate and the bottom end surface of the feed hopper is 20 cm.
[0019] When the crushed vanadium-nitrogen material falls, the second motor drives the rotating rod to rotate, thereby rotating the guide plate. The guide plate can guide the vanadium-nitrogen material, slowing down the force of its contact with the screen, effectively ensuring the quality of the screen, and at the same time, the crushed vanadium-nitrogen material can be spread over a large area to ensure screening efficiency.
[0020] Compared with the prior art, the beneficial effects of the present invention are:
[0021] When the utility model is in use, the vanadium-nitrogen material is put into the feed hopper, and the first motor is started to drive the connecting shaft to rotate, and the connecting shaft drives the driving gear to rotate, thereby causing the driven gear to rotate. At this time, the rotating shafts on one side of the driving gear and the driven gear drive the crushing rollers on the outer sides of the rotating shaft to rotate in opposite directions. At this time, the vanadium-nitrogen material can be effectively crushed, and the crushed material directly falls into the screening equipment below, greatly improving the screening efficiency of the vanadium-nitrogen material.
[0022] And when the crushed vanadium nitrogen material falls, it drives the rotating rod to rotate through the second motor, thereby rotating the guide plate. The guide plate can guide the vanadium nitrogen material, slow down the force of its falling contact with the screen, effectively ensure the quality of the screen, and at the same time, the crushed vanadium nitrogen material can be spread over a large area to ensure screening efficiency.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Example 1
[0031] See also Figure 1 、 Figure 2 and Figure 4 , the utility model provides a technical solution:
[0032] A vanadium nitride crushing and screening device includes a positioning frame 1, a screening device 2 and a feed hopper 3.
[0033] A screening device 2 for screening vanadium-nitrogen materials is installed on the inner side of the positioning frame 1, and the screening mesh of the screening device 2 is arranged at an angle;
[0034] A vertical feed hopper 3 is installed on the top of the positioning frame 1. A crushing mechanism 5 for crushing vanadium-nitrogen materials is installed inside the feed hopper 3. A guide block 4 is provided above the crushing mechanism 5, and an adjustment mechanism 6 fixedly connected to the positioning frame 1 is provided below the crushing mechanism 5.
[0035] The crushing mechanism 5 includes a first mounting plate 501, a first motor 502 and a connecting shaft 503. The outer side of the first mounting plate 501 is fixedly connected to the feed hopper 3. The first motor 502 is fixedly connected to the top of the first mounting plate 501. The end of the main shaft of the first motor 502 is fixedly connected to the connecting shaft 503. The other end of the connecting shaft 503 is fixedly connected to a driving gear 504. The outer side of the driving gear 504 is meshed with a driven gear 505.
[0036] The other ends of the driving gear 504 and the driven gear 505 are fixedly connected to a rotating shaft 506 , and the outer sides of the rotating shaft 506 are fixedly connected to a crushing roller 507 . Both ends of the rotating shaft 506 are rotatably connected to the feed hopper 3 .
[0037] The feed hopper 3 is configured to be wide at the top and narrow at the bottom.
[0038] There are two groups of crushing rollers 507 , and the crushing rollers 507 are distributed on both sides of the feed hopper 3 .
[0039] The existing vanadium nitrogen materials have the following problems when in use. First, equipment is required to crush them specifically, and then they are transferred to the screening equipment for screening after crushing. The crushing and screening require two types of equipment, which seriously affects the screening efficiency. Secondly, during screening, the vanadium nitrogen materials often fall to the same position of the screening mesh of the screening equipment. Long-term direct falling and pressure may cause the screen mesh to be locally concave and damaged, affecting the subsequent screening quality. When the device is in use, an external power supply is connected, and the vanadium nitrogen materials are put into the feed hopper 3. By starting the first motor 502 to drive the connecting shaft 503 to rotate, the connecting shaft 503 drives the driving gear 504 to rotate, thereby rotating the driven gear 505. At this time, the rotating shaft 506 on one side of the driving gear 504 and the driven gear 505 drives the crushing roller 507 on the outside of the rotating shaft 506 to rotate in opposite directions. At this time, the vanadium nitrogen material can be effectively crushed, and the crushed material falls directly into the screening equipment below, greatly improving the screening efficiency of the vanadium nitrogen material.
[0040] In this embodiment, the screening mesh of the screening device 2 inside the positioning frame 1 is set at an angle. At this time, when the screening action is performed, the screening mesh is aimed at, and the material gradually moves to the lower side, and the fine-grained material falls into the interior of the screening device 2 and is discharged from the bottom discharge port, and the large-grained material falls from one side, thereby achieving effective separation.
[0041] Example 2
[0042] This embodiment is an improvement on embodiment 1. Figure 3 Specifically, there are two groups of guide blocks 4, and the outer sides of the guide blocks 4 are fixedly connected to the feed hopper 3.
[0043] The upper end surface of the guide block 4 is inclined, and the bottom of the guide block 4 is in contact with the crushing roller 507 .
[0044] The setting of the guide block 4 ensures that the material moves fully to the center of the crushing rollers 507 on both sides, ensuring that the material is fully crushed. The bottom of the guide block 4 is set in an arc shape and contacts the crushing roller 507. At this time, it can play a role in removing the material attached to the surface of the crushing roller 507, play a certain cleaning purpose, and ensure the normal use of the crushing roller.
[0045] Example 3
[0046] This embodiment is an improvement on embodiment 2. Figure 5Specifically, the above-mentioned adjusting mechanism 6 includes a second mounting plate 601, a second motor 602 and a rotating rod 603. The outer side of the above-mentioned second mounting plate 601 is fixedly connected to the feed hopper 3. The second motor 602 is fixedly connected to the top of the above-mentioned second mounting plate 601. The end of the main shaft of the above-mentioned second motor 602 is fixedly connected to the rotating rod 603. The outer side of the above-mentioned rotating rod 603 is fixedly connected to a guide plate 604. The two sides of the above-mentioned rotating rod 603 are rotatably connected to the feed hopper 3.
[0047] The vertical distance between the bottom end surface of the guide plate 604 and the bottom end surface of the feed hopper 3 is 20 cm.
[0048] When the crushed vanadium-nitrogen material falls, it drives the rotating rod 603 to rotate through the second motor 602, thereby rotating the guide plate 604. The guide plate 604 can guide the vanadium-nitrogen material, slow down the force of its falling contact with the screen, effectively ensure the quality of the screen, and at the same time, the crushed vanadium-nitrogen material can be guided and spread over a large area to ensure screening efficiency. The second motor 602 is rotated back and forth 45° by an external control unit.
