Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pellet detection, and particularly relates to a pellet compression strength detection device. BACKGROUND

[0002] Pellets are important raw materials for modern blast furnace ironmaking, and the compression strength thereof is one of key indexes for evaluating pellet quality and ensuring smooth operation of the blast furnace. Pellets with unqualified compression strength are prone to breakage in the transportation and smelting process, which leads to poor blast furnace permeability and affects production efficiency and molten iron quality. Therefore, it is crucial to quickly and accurately detect the compression strength of the pellets.

[0003] The existing pellet compression strength detection mainly relies on a special material testing machine. In this process, an operator needs to manually place a single pellet in the center of the pressure disc of the testing machine, and then start the equipment for pressing until the pellet breaks, and record the maximum pressure value at the breaking moment as the compression strength of the pellet. Although the use of automatic clamping jaws or vibration feeding can replace manual operation, the clamping jaws may generate pressure on the pellets, which may cause the pellets to break during feeding. The vibration feeding cannot screen the bonded irregular pellets, and the dumbbell-shaped or triangular pellets formed during production cannot represent the standard detection data, thereby affecting the detection accuracy. Meanwhile, the irregular pellets automatically entering the detection equipment may cause the equipment to be stuck. After detection, the pellet residues scatter around the equipment, which needs to be cleaned manually, thereby increasing the additional working steps and causing waste. Therefore, it is necessary to design a pellet compression strength detection device. SUMMARY

[0034] Please refer to Figures 1-7The residue processing mechanism 7 comprises a rotating frame 71 rotatably connected between the inner support 4 and the main support 1, the inner wall top of the rotating frame 71 is uniformly provided with a cleaning scraping block 72, the bottom of the cleaning scraping block 72 is a flexible sponge structure, and the sponge structure at the bottom of the cleaning scraping block 72 is attached to the top of the inner support 4. During movement, the cleaning scraping block 72 can adapt to the shape change of the lower surface and always attach to the inner support 4. The top of the inner support 4 is uniformly provided with a residue discharge port 73, and the residue discharge port 73 is fixedly connected with a collection shell 75. The rotating frame 71 is fixedly connected with a connecting piece 74, and the connecting piece 74 is fixedly sleeved on the center column 57. During rotation of the center column 57, the connecting piece 74 drives the rotating frame 71 to rotate synchronously. After the balling pellet is detected by the detection unit 2, the balling pellet is deformed to generate residue. The residue after detection is pushed to the residue discharge port 73 by the rotating cleaning scraping block 72. The residue falls from the residue discharge port 73 into the collection shell 75 for centralized collection. Then, the balling pellet can be prepared again by crushing and sintering.

[0035] It should be noted that when the balling pellet compression strength detection device is used, the sampling balling pellet to be detected is first put into the processing shell 61. Part of the balling pellet directly enters the inclined conveying pipe 56 and rolls along the inclined conveying pipe 56 in turn until the balling pellet at the bottom presses against the side wall of the center rotating disc 51. Then, the rotating motor 58 is started to drive the center column 57 to rotate. When the transfer groove 52 on the center rotating disc 51 moves to the position of the inclined conveying pipe 56, the balling pellet at the bottom rolls out of the inclined conveying pipe 56 into the transfer groove 52 and moves with the center rotating disc 51. The remaining balling pellet is blocked by the side wall of the center rotating disc 51 and stays in the inclined conveying pipe 56 for next time entering the transfer groove 52. The balling pellet in the transfer groove 52 contacts and enters the guide groove 54 of the guide frame 53 during rotation of the center rotating disc 51. Then, the balling pellet can roll down along the guide groove 54 under the action of gravity. After that, the balling pellet rolls to the bottom of the detection unit 2 under the guidance of the detection guide groove 55 for detection. The feeding process of single balling pellet can be accurately realized without manual participation, and the detection efficiency is high. At the same time, the smooth detection is avoided due to the simultaneous entry of multiple balling pellets into the detection position.

[0036] During detection, the rotating motor 58 is stopped, the lifting screw 22 is driven by the lifting motor 23, the floating support 28 is pulled downward by the downward pressing bracket 27 through the floating support 28, and the floating support 28 is completely nested on the top of the inner support 4 until the floating support 28 is completely nested on the top of the inner support 4. The floating support 28 and the inner support 4 are combined into a complete detection plane. The downward pressing block 25 continues to move downward and presses against the balling pellet. The pressure is provided by continuous pressing. During the process, the deformation of the balling pellet is collected by the industrial vision sensor 8. At the same time, the pressure received by the balling pellet is collected by the pressure sensor 24 during the pressing of the balling pellet. The compression strength of the balling pellet is detected by combining the pressure data with the deformation of the balling pellet.

[0037] After the detection is completed, the lifting motor 23 drives the lifting screw rod 22 to rotate reversely to make the lower pressing block 25 move upward, and in the process, the relative position between the floating support 28 and the inner support 4 is maintained under the elastic force of the supporting spring 29, then the rotating motor 58 is started, and the center column 57 rotates, and the connecting piece 74 drives the rotating frame 71 to rotate synchronously, after the ball is pressed and detected by the detection unit 2, the ball is deformed to generate residues, the residues after the detection are pushed to the residue discharge port 73 by the rotating cleaning scraper 72, and the residues fall from the residue discharge port 73 to the collection shell 75 for centralized collection, and then the residues can be prepared into the ball again by crushing and sintering, after the residues are pushed away by the cleaning scraper 72, the lower pressing block 25 continues to move upward, the floating support 28 is driven by the supporting spring 29 to move upward and disengage from the groove on the inner support 4 to return to the original position and wait for the next test;

[0038] During the whole detection process, the intermittent rotation of the center column 57 can stir the accumulated ball in the processing shell 61 at a low speed through the turning block 65, so that the ball enters the four inclined conveying pipes 56, and at the same time, the hot air introduced by the connecting pipe 63 blows on the ball through the air outlet 64, and the accumulated ball is dried by the rotating turning block 65, and the irregularly shaped ball that is mutually adhered during the preparation process cannot enter the inclined conveying pipe 56 due to the size limitation, and is retained in the processing shell 61, which can effectively prevent the irregularly shaped ball from causing the equipment to be stuck, and the ball is sorted in advance to avoid the interference of the irregularly shaped ball on the detection data.

[0039] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
