Description

Technical Field

[0001] The utility model belongs to the technical field of fire assay analysis devices, and in particular relates to a furnace loading device which is safe, reliable and capable of batch operation. Background Art

[0002] The fire assay gravimetric method is used to determine the amount of gold in minerals. The crucible containing the mixed material needs to be placed in the assay furnace. Due to the high temperature of the assay furnace, a furnace loading device is needed to load the crucible into the assay furnace to achieve the experimental purpose.

[0003] Traditional fire assay furnace loading equipment is a single-hole chuck, which can only be used by the operator to pick up the crucible with a fork and clamp a single crucible into the high-temperature assay furnace, and move the crucibles into the assay furnace one by one. Currently, the commonly used high-temperature assay furnace can generally accommodate 20 to 80 assay crucibles. Using a single-hole chuck to move multiple crucibles one by one into the high-temperature assay furnace takes a long time and has low work efficiency, which affects production efficiency. It not only increases the labor intensity of the operator, but also causes the high-temperature assay furnace to cool down more.

[0004] In addition, when loading the crucible into the high-temperature gold assay furnace, the heat emitted by the high-temperature gold assay furnace will also cause harm to the operator. The operator may get burns on the hands and face if he works in front of the high-temperature furnace for a long time. This type of device consumes a lot of physical strength of the operator, the furnace loading speed is slow, and the heat loss is large, resulting in energy waste. At the same time, fire assay laboratories generally use electric heating equipment, and there is a risk of electric shock when using traditional fire assay grippers.

[0005] Therefore, in actual work, how to reduce the operator's labor intensity, improve work efficiency, and reduce energy waste while ensuring the operator's safety is an urgent problem to be solved in this field. Summary of the invention

[0006] In order to overcome the above problems, the utility model provides a safe, reliable and batch-operated furnace loading device for loading gold assay crucibles into gold assay furnaces, which not only improves the safety and working efficiency of the equipment, but also reduces labor intensity and energy waste.

[0007] A safe, reliable and batch-operated furnace loading device comprises a control handle 1, a frame, a booster cylinder 3, a chuck 4, a vehicle body 5 and moving wheels 6, wherein a plurality of moving wheels 6 are provided at the bottom of the vehicle body 5, the booster cylinder 3 is fixed above the front end of the vehicle body 5, the rear end of the frame is movably connected above the rear end of the vehicle body 5, the front end is fixed to the telescopic end of the booster cylinder 3, and the front end end thereof is provided with a chuck 4; the control handle 1 is fixed to the rear end of the frame.

[0010] A chuck holder 9 is fixed to the front end of the front extension rod 7 , and the chuck 4 is fixed to the front end of the chuck holder 9 .

[0011] It also includes a rotating shaft 12 , wherein the rotating shaft 12 passes through the rear extension rod 8 , the rotating bracket 13 and the connecting rod 11 in sequence from the outside to the inside, and the rotating shafts 12 are connected together through the rotating rod 2 .

[0012] The bottom of the booster cylinder 3 is fixed on the vehicle body 5 through a base.

[0013] The chucks 4 are provided in multiple rows and are fixed on the chuck holder 9 from left to right in sequence, wherein the leftmost chuck 4 is provided with multiple semicircular grooves on the inner side, the middle multiple chucks 4 are provided with semicircular grooves on the left and right sides respectively, which are the same number and correspond to the leftmost chuck 4, and the rightmost chuck is provided with semicircular grooves on the left side which are the same number and correspond to the leftmost chuck 4.
