Description

Technical Field

[0001] This utility model belongs to the field of particle size detection technology, specifically relating to a vanadium-titanium pellet particle size detection mechanism. Background Technology

[0002] Vanadium-titanium pellets are artificial blocky raw materials for blast furnace ironmaking, made primarily from vanadium-titanium magnetite through processes such as fine grinding, batching, pelletizing, and high-temperature roasting.

[0003] In existing technologies, vanadium-titanium pellets are one of the three major iron-containing raw materials for modern blast furnaces. Their main purpose is to provide a stable, efficient, and high-quality iron source for the blast furnace. Before vanadium-titanium pellets are put into use, their particle size needs to be tested. If the particle size is too large, the core part will be difficult to reduce. If the particle size is too small, it will be easily carried away by the airflow and enter the dust without fully reacting.

[0004] However, the particle size of vanadium-titanium pellets is currently generally detected by manual sieving. Due to different manual operation methods, the detection results are prone to poor accuracy and low efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a vanadium-titanium pellet particle size detection mechanism with a simple structure and reasonable design in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A vanadium-titanium pellet particle size detection mechanism includes a detection chamber, a particle size sieving mechanism, and a vanadium-titanium pellet mixing assembly.

[0008] The upper surface of the detection chamber is equipped with a vanadium-titanium pellet mixing component capable of mixing randomly selected vanadium-titanium pellets.

[0009] The testing chamber is equipped with a particle size screening mechanism that can screen vanadium-titanium pellets.

[0010] The particle size separation mechanism is located below the vanadium-titanium pellet mixing assembly;

[0011] The particle size screening mechanism includes a screening component and a driving component, which are connected and located inside the detection chamber, while the driving component is located outside the detection chamber.

[0012] As a further optimization of this utility model, the vanadium-titanium pellet mixing assembly includes a mixing chamber, the lower end of which is fixedly disposed on the upper surface of the detection chamber, the interior of the mixing chamber is connected to the interior of the detection chamber, a valve is fixedly disposed at the connection between the detection chamber and the mixing chamber, a second motor is fixedly disposed on the upper surface of the mixing chamber, and a stirring blade is fixedly disposed at the output end of the second motor, the stirring blade being located inside the mixing chamber.

[0013] As a further optimization of this utility model, the screening component includes multiple sets of vertical positioning blocks and two sets of first transverse positioning blocks. The multiple sets of vertical positioning blocks are symmetrically fixed in pairs on the inner wall of the detection chamber. The two sets of first transverse positioning blocks are symmetrically fixed on the inner wall of the detection chamber. Multiple sets of support frames are slidably arranged between the multiple sets of vertical positioning blocks. A screening plate is slidably arranged on the inner surface of the support frame. Multiple sets of fixing blocks are fixed on one side surface of the screening plate. A protrusion is fixed on one side surface of the support frame. Multiple sets of bolts are threaded to the upper surface of the support frame. Multiple sets of second transverse positioning blocks are fixed on the inner surface of the support frame. A receiving plate is slidably arranged between the two sets of first transverse positioning blocks.

[0014] As a further optimization of this utility model, a first transverse positioning groove is provided on the side surface of the receiving plate, the first transverse positioning block and the first transverse positioning groove are slidably connected, the bolt and the fixing block are rotatably connected, multiple sets of slots are provided on the side surface of the screening plate opposite to the fixing block, multiple sets of grooves are provided on the side surface of the support frame opposite to the bolt, the slots and grooves are engaged, and a second transverse positioning groove is provided on the side surface of the screening plate, the second transverse positioning groove and the second transverse positioning block are slidably connected.

[0015] As a further optimization of this utility model, multiple sets of vertical positioning grooves are provided on the side surface of the support frame, the vertical positioning blocks are in contact with the vertical positioning grooves and are slidably connected, and the multiple sets of screening plates are arranged in an array from top to bottom, and the diameter of the filter screens on the surface of the screening plates decreases from top to bottom.

[0016] As a further optimization of this utility model, the driving component includes a first motor, which is fixedly mounted outside the detection chamber. A rotating rod is fixedly connected to the output end of the first motor. A transmission bracket is movably passed through the outer surface of the rotating rod. A movable plate is rotatably connected to the lower end of the transmission bracket. A connecting bracket is rotatably connected to the inner wall of the movable plate. A connecting rod is rotatably connected to the upper end of the connecting bracket. The outer surface of the connecting rod is fixedly connected to multiple sets of protrusions. A fixed rod is rotatably connected to the other end of the movable plate. The fixed rod is fixed to the outer surface of the detection chamber.

[0017] The beneficial effects of this utility model are as follows: First, vanadium-titanium pellets at various locations on the production line are randomly sampled. After sampling, the vanadium-titanium pellets are put into the mixing chamber. Then, the second motor is started to drive the stirring blades to rotate, so that the vanadium-titanium pellets at various locations are evenly mixed. After mixing, the gate at the connection between the mixing chamber and the testing chamber is opened, so that a certain number of vanadium-titanium pellets enter the testing chamber. Random sampling avoids the uniqueness of the sample, thus making the sample representative.

[0018] The vanadium-titanium pellets that enter the testing chamber first accumulate on the top screening plate. At this time, the first motor is started to drive the rotating rod to rotate. Since the rotating rod is not at the center, the rotation of the rotating rod will drive the transmission bracket to move up and down in a small circular motion. This will cause the movable plate to move up and down around the connection between the fixed rod and the movable plate as the center. The up and down movement of the movable plate will drive the connecting rod to move up and down in a circular motion. The connecting rod will drive all the support frames to move up and down in a circular motion, thereby causing all the screening plates to vibrate up and down. The vibration frequency of the screening plates can be controlled by adjusting the speed of the first motor.

[0019] The vibrating sieve plates will sieve the vanadium-titanium pellets one by one, separating vanadium-titanium pellets of different particle sizes. Finally, open the side door of the detection chamber, remove the bolts, and all the sieve plates and the bottom receiving plate can be pulled out of the detection chamber. Then, calculate the weight of the vanadium-titanium pellets on each sieve plate and receiving plate, and finally obtain the average particle size of the vanadium-titanium pellets, thus achieving the purpose of particle size detection.

The multiple sets of vertical positioning blocks 8 are symmetrically fixed in pairs on the inner wall of the detection chamber 1. The two sets of first transverse positioning blocks 9 are symmetrically fixed on the inner wall of the detection chamber 1. Multiple sets of support frames 11 are slidably arranged between the multiple sets of vertical positioning blocks 8. A screening plate 10 is slidably arranged on the inner surface of the support frame 11. Multiple sets of fixing blocks 16 are fixed on one side surface of the screening plate 10. A protrusion 15 is fixed on one side surface of the support frame 11. A dustproof cloth is provided at the connection between the protrusion 15 and the inner wall of the detection chamber 1. The dustproof cloth is elastic to prevent vanadium-titanium pellets from being ejected from the detection chamber 1 due to vibration. Multiple sets of bolts 21 are threadedly connected to the upper surface of the support frame 11. Multiple sets of second transverse positioning blocks 22 are fixed on the inner surface of the support frame 11. A receiving plate 12 is slidably arranged between the two sets of first transverse positioning blocks 9.

[0036] The receiving plate 12 has a first transverse positioning groove 13 on its side surface. The first transverse positioning block 9 and the first transverse positioning groove 13 are in a sliding connection. The bolt 21 is in a rotating connection with the fixing block 16.

[0039] In actual use, vanadium-titanium pellets at various locations on the production line are first randomly sampled. After sampling, the vanadium-titanium pellets are put into the mixing chamber 5.

After mixing, the gate at the connection between the mixing chamber 5 and the detection chamber 1 is opened, so that a certain number of vanadium-titanium pellets enter the detection chamber 1. Random sampling avoids the uniqueness of the sample, thus making the sample representative.

[0040] The vanadium-titanium pellets that enter the testing chamber 1 first accumulate on the top screening plate 10. At this time, the first motor 4 is started to drive the rotating rod 23 to rotate. Since the rotating rod 23 is not at the center, the rotation of the rotating rod 23 will drive the transmission bracket 24 to move up and down in a small circular motion, thereby driving the movable plate 25 to move up and down in a circular motion around the connection between the fixed rod 27 and the movable plate 25. The up and down movement of the movable plate 25 will drive the connecting rod 14 to move up and down in a circular motion, and the connecting rod 14 will drive all the support frames 11 to move up and down in a circular motion, thereby causing all the screening plates 10 to vibrate up and down. The vibration frequency of the screening plates 10 can be controlled by adjusting the speed of the first motor 4.

[0041] The vibrating sieve plate 10 will sieve the vanadium-titanium pellets one by one, separating vanadium-titanium pellets of various particle sizes. Finally, the side door of the detection chamber 1 is opened, and the bolt 21 is removed, so that all the sieve plates 10 and the bottom receiving plate 12 can be pulled out of the detection chamber 1. Then the weight of the vanadium-titanium pellets on each sieve plate 10 and receiving plate 12 is calculated, and finally the average particle size of the vanadium-titanium pellets is obtained, thereby achieving the purpose of particle size detection.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but 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 several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
