Description

Technical Field

[0001] The utility model relates to the technical field of pellet pressure detection, and specifically relates to a device for detecting the compressive strength of pellets. Background Technique

[0002] The compressive strength of pellets refers to the maximum crushing load under which the pellets are pressed, and it is an index characterizing the mechanical strength of the pellets. Before and after iron ore pellets enter the blast furnace or direct reduction furnace kiln, after multiple loading, unloading, transportation, stacking and movement, they have to withstand various harsh mechanical actions such as collision, impact, extrusion and friction, and need to be detected by a compressive strength detection device.

[0003] When optimizing the existing devices for detecting the compressive strength of pellets, most of them are reflected in facilitating the operation of the operator and improving the detection efficiency. For example, the Chinese utility model patent with the application number CN201410136515.4 discloses "A Device for Detecting the Compressive Strength of Pellets". In this device, it includes an angle adjustment mechanism, a transmission unit, a material supply unit, a cleaning and positioning unit, a press and a support unit. The angle adjustment mechanism is connected to the upper end of the support unit, the transmission unit and the material supply unit are respectively connected to the angle adjustment mechanism, the transmission unit is connected to the material supply unit, the material supply unit is connected to the press, the cleaning and positioning unit and the press are respectively connected to the upper end of the support unit. The transmission unit drives the material supply unit to rotate, so that the pellets can be automatically conveyed into the press for compressive strength detection, improving the efficiency of the device for detecting the compressive strength of pellets and reducing the detection cost.

[0004] Although the above-mentioned device for detecting the compressive strength of pellets has certain advantages in facilitating the operation of the operator and improving the detection efficiency, it still has certain drawbacks: The pellets are crushed under pressure before the compressive strength detection ends. When the detection ends, the pellets are broken into small pieces and powder, and there will be pellet slag residues remaining on the detection table. If the tabletop is not cleaned in time, it will not only make the tabletop dirty, but also cause the tabletop to be uneven, affecting the unstable placement of the next pellet and resulting in inaccurate compressive detection results.
