Description

Iron ore falling strength test trolley

Technical Field

The utility model belongs to the technical field of metallurgical test equipment, more specifically says, relates to an iron ore intensity test dolly that falls.

Background

Before the iron ore enters the smelting process, the iron ore needs to be conveyed to a high position through a belt and falls into a smelting container, and the frangibility degree of the iron ore in the process reflects the falling strength of the iron ore. The falling strength of the iron ore is detected through a falling strength test in a laboratory, the traditional iron ore falling strength detection method is that a trolley brings the test ore to a high position, and after the test ore reaches the test height, the trolley opens the bottom, so that the iron ore falls from the trolley. Because the experiment is high, can produce a large amount of raise dusts after iron ore falls, produce adverse effect to the tester health, and iron ore can scatter at the process of falling, and the iron ore collection degree of difficulty after the experiment is big, and the experimental degree of accuracy reduces.

In order to solve the disadvantages of the test process, the separation height of the iron ore and the trolley can be reduced. For example, after the trolley is filled with ores at a low position, the trolley is driven to a high position by the traction device, then the trolley falls down from the high position together with the iron ores, and when the trolley falls down, the bottom of the trolley is opened, so that the falling process of the iron ores in the trolley is not influenced, the dust raising can be inhibited to the maximum extent, and the test accuracy is improved; the opening and closing of the bottom of the trolley are controlled by mounting electronic elements such as a limiting stopper at the bottom of the trolley. However, due to the complex test environment of the falling strength of the iron ore, the dust, the violent collision and other factors, the electronic element is easily damaged and fails in the test process, so that the bottom of the trolley cannot be opened in time, and the effective test result is difficult to obtain and other equipment is damaged.

Through the retrieval, the chinese utility model patent that the grant bulletin number is CN207923620U discloses a sintering intensity detection device that falls, including frame and the hopper that falls of setting in the frame, the bottom of the hopper that falls is equipped with the dodge gate, is equipped with the dodge gate opening and closing mechanism that is used for the switching dodge gate on the hopper that falls, and the intensity detection device that falls still includes: the falling hopper is arranged on the vertical guide rail in a sliding manner; the lifting mechanism is connected with the falling hopper and used for lifting the falling hopper to a preset height; the horizontal guide rail is arranged at the bottom of the rack, and one end of the horizontal guide rail is positioned right below the vertical guide rail; the material transfer mechanism is slidably arranged on the horizontal guide rail and is mainly used for receiving the materials falling from the falling hopper and reloading the materials into the falling hopper for carrying out multiple falling strength detection; the controller, the lifting mechanism, the material transferring mechanism and the movable door opening and closing mechanism are all connected with the controller; the problem of prior art's detection device inconvenient operation has been solved to this scheme.

However, the above-mentioned solution fails to solve the problem that the testing environment for the falling strength of the iron ore is complex, and the electronic components of the material trolley and other devices are very easily damaged and fail, so that there is an urgent need for a device that can have a longer service life in the testing environment of the falling strength test of the iron ore filled with dust and severe collision.
