Description

Technical Field

[0001] This utility model relates to the field of ignition reduction technology, specifically an automatic bauxite ignition reduction testing device. Background Technology

[0002] With the rapid development of the metallurgical industry and the rapid improvement of sample preparation technology, the workload of sample preparation has increased significantly, among which the loss on ignition step is crucial. "Loss on ignition," or "weight loss on ignition" for short, is a commonly used indicator in materials analysis. Its core function is to measure the content of volatile or decomposable components in a material by measuring the mass change before and after high-temperature ignition. In the bauxite sample preparation process, the sample needs to be ignited at 1200℃ for an extended period. The weight of the sample after ignition is compared with that before ignition to provide data for sample analysis.

[0003] The data obtained from ignition directly affects the analysis results of the sample. In existing technologies, most of the operation is done manually, which leads to low efficiency. At the same time, the proximity to the heat source increases the risk, and the data accuracy is also poor due to untimely operation, which seriously affects product quality.

[0004] Based on the above reasons, this utility model designs an automatic bauxite loss on ignition test device, which can automatically ignite the sample for a long time. The temperature and heating curve can be set by the program. The sample inlet can be opened and closed automatically. It has good heat preservation effect, small temperature fluctuation, and accurate ignition value. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic bauxite loss on ignition test device that can automatically ignite the sample for a long time. The temperature and heating curve can be set by the program. The sample inlet can be opened and closed automatically. It has good heat preservation effect, small temperature fluctuation, and accurate ignition value.

[0006] To achieve the above objectives, this utility model provides an automatic bauxite loss on ignition testing device, including a welding frame connected to the bottom surface via feet. A control cabinet is installed inside a portion of the welding frame, and a multi-layered ignition furnace is installed in another portion of the welding frame. A fan is installed on the top cover of the welding frame. A column supporting the furnace chamber is installed on one side of the bottom plate of the ignition furnace, and a guide rod is installed on the other side of the bottom plate. A lifting device is installed on the connector on the guide rod, and a lifting platform is installed on the lifting device. A crucible is installed on the lifting platform, and the upper end of the lifting device is connected to the furnace chamber. A fan is installed on one side of the furnace chamber shell.

[0007] Two heat dissipation vents are provided on one side of the welding frame where the furnace is located.

[0008] A heat dissipation vent is provided on the back of the furnace.

[0009] The calcination furnaces are placed in three layers, one on each side, within the welding frame.

[0010] The dimensions of the lifting platform are consistent with the dimensions of the bottom surface of the furnace.

[0011] The outer shell of the furnace is made of heat-insulating material.

[0012] Compared with the existing technology, this utility model places the crucible on a liftable lifting platform, which can automatically rise into the furnace for sintering, avoiding the traditional method of manual placement, making it easier to pick up and put down the crucible, ensuring the safety of the operation process, and improving efficiency to a certain extent.

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See Figs. 1-5 This utility model provides an automatic bauxite loss on ignition test device, including a welding frame 1 connected to the bottom surface 12 by foot, a control cabinet 2 inside a part of the welding frame 1, and a multi-layered ignition furnace 4 inside another part of the welding frame 1. A fan 3 is installed on the top cover 13 of the welding frame 1. A column 7 supporting the furnace chamber 5 is installed on one side of the bottom plate of the ignition furnace 4, and a guide rod 8 is installed on the other side of the bottom plate. A lifting device 9 is installed on the connector on the guide rod 8, a lifting platform 6 is installed on the lifting device 9, and a crucible 11 is installed on the lifting platform 6. The upper end of the lifting device 9 is connected to the furnace chamber 5, and a fan 10 is installed on one side of the outer shell of the furnace chamber 5.

[0021] A heat dissipation vent 15 is provided on one side of the welding frame 1 where the furnace 4 is mounted.

[0022] A heat dissipation vent 14 is provided on the back of the furnace chamber 5.

[0023] The calcination furnace 4 is placed in three layers, one on each layer, within the welding frame 1.

[0024] The dimensions of the lifting platform 6 are consistent with the bottom dimensions of the furnace chamber 5.

[0025] The outer shell of furnace chamber 5 is made of heat-insulating material.

[0026] Working principle: This invention requires minimal debugging during use. An industrial robot places the crucible 11 containing the sample onto the lifting platform 6. The lifting device 9, guided by the guide rod 8, elevates the lifting platform 6, sending the crucible 11 into the furnace chamber 5. Simultaneously, the furnace chamber 5 is sealed and insulated. The furnace chamber 5 heats according to a pre-set program until the set temperature and time are reached. After the burning time is reached, the lifting device 9 lowers the lifting platform 6, and the industrial robot removes the crucible 11 for weighing. The fan 10 on the outer shell of the furnace chamber 5 continuously heats the furnace control unit. The control unit is equipped with high-temperature sensors and timers, and the collected data is fed back to the main control unit in the control cabinet 2 in real time. The main control unit records and analyzes the information. The circuit connections and mechanical kinetic principles of the lifting platform 6, lifting device 9, fan 10, and blower 3 inside the device are all existing technologies or implemented according to their built-in functions. These are common and publicly available technical means in the industry and are not the main improvement and protection object of this invention. Therefore, they will not be described further.
