Description

Technical Field

[0001] The utility model belongs to the technical field of fire assay mixing equipment, in particular to a mixing equipment capable of loading and unloading materials in batches. Background Art

[0002] The fire assay analysis method is the main detection method for gold and silver analysis and trade arbitration in the gold industry at home and abroad. This method has the advantages of wide application range, large sampling volume, good representativeness, and accurate and reliable results. Among them, mixing the sample is an extremely important step, and the quality of sample mixing plays a decisive role in the test results. After batching, the sample and reagents such as sodium carbonate, borax, glass powder and lead oxide are placed in a crucible in a certain proportion. After adding, they need to be fully mixed. The traditional mixing equipment is to manually put these prepared crucibles into the designated mixing position by personnel. After placing them, the crucible cup is in direct contact with the elastic layer, and then flipped. After the flipping is completed, personnel need to manually take the crucibles out of the position one by one in order, and knock on each crucible wall with a stirring rod to make the sample on the crucible wall fall back into the crucible, and then stir it again to fully mix the knocked samples until they are completely mixed.

[0003] This traditional mixing method has the following defects:

[0004] First, after adding the reagents, personnel are required to load and unload the materials. There are many uncertainties in loading and unloading. Because manual transfer is required, it is easy for the order of two or more samples to go wrong, which can easily cause serious quality accidents. In addition, during the transfer process, it is easy for samples to overflow, causing losses. Moreover, the manual transfer efficiency is very low, which affects the timeliness of reporting results.

[0005] Secondly, after the traditional stirring equipment is finished, there will be a large amount of sample residue on the crucible wall, and the personnel need to manually knock the crucible wall with a stirring rod. In addition, after the sample on the crucible wall falls into the center, the personnel also need to manually stir the sample to fully mix the sample that falls into the center. This series of operations is very cumbersome and inefficient. At the same time, manual stirring by personnel is also prone to cause loss of sample;

[0006] Finally, the traditional stirring equipment allows the sample to directly contact the elastic layer and cannot be replaced. The mouth of some crucibles is very sharp, which will inevitably cause damage to the elastic layer. In addition, the direct contact between the sample and the elastic layer will inevitably lead to sample residue, which will affect the experimental data of the sample. Summary of the invention

[0007] In order to overcome the above problems, the utility model provides a mixing device that can load and unload materials in batches, so as to solve the problems that traditional mixing equipment is easy to be serialized and inefficient, the experimental data is not accurate enough, it cannot be used after the elastic layer is damaged, and there is a lot of manual intervention.

[0056] When working, the crucible rack 3 is filled with crucibles, and the sample and reagent are added to the crucible in a certain proportion, and then the cylinder 9 is turned on, so that its telescopic end drives the lower connecting plate 66 and the upper connecting plate 65, so that the sleeve of the lifting mechanism 61 slides downward along the connecting rod until the sleeve is at the lower limit position of the connecting rod;

[0057] Push the crucible stand trolley 1 to mate the boss 21 with the connection hole 11. After confirming that the mate is correct, release the limit of the screw 14, that is, remove the screw 14;

[0058] Push the crucible stand 3 to move it out of the crucible stand trolley 1 through the pulley 12, continue to push the crucible stand 3, push it to the upper connecting plate 65, and slide it into the upper connecting plate 65 through the second pulley 8.
