Description

Technical Field

[0001] The utility model relates to the technical field of slurry sampling devices, in particular to a sealable slurry sampling device. Background Art

[0002] In the process of controlling the flotation technical indicators of the ore dressing plant, the grade of raw materials, intermediate materials, and concentrate tailings products is an important basis for evaluating the quality of production indicators and examining the metal balance. It is also a key parameter for measuring the metal recovery rate and other technical indicators and economic benefits of the ore dressing plant. Therefore, the rationality and representativeness of sampling are crucial to the production organization of the ore dressing plant. In the ore sorting process, it is a normalized work to conduct chemical analysis and concentration inspection on the slurry in the process. Usually, ordinary sampling spoons are used to take slurry. This sampling method has little effect on small flotation machines or shallow trough flotation machines, but there are certain defects in the sampling work of deep trough flotation machines: because the slurry layer of the deep trough flotation machine is deep and the slurry is obviously stratified, the commonly used sampling spoon opens upward, and the lighter slurry on the upper layer enters the sampling spoon first during sampling, while the slurry on the lower layer is difficult to enter the sampling spoon. For this reason, we propose a closed slurry sampling device. Utility Model Content

When the fixing rod 6 is pulled, the fixing rod 6 drives the second connecting rod 8 and the cover plate 9 to move in the vertical direction, so that the cover plate 9 and the sealing block 10 are separated. At this time, the slurry can enter the sampling tank 1 through the opening at the upper end of the sampling tank 1. When the fixing rod 6 is not applied, the sleeve 5 moves on the first connecting rod 2 under the action of the elastic force of the spring 7. Through the transmission of the fixing rod 6 and the second connecting rod 8, the cover plate 9 and the sealing block 10 can automatically seal the sampling tank 1. Blocks 11 are provided on both sides of the upper end of the sampling tank 1. The sealing block 10 is provided with a card slot 12 matching the block 11. When the cover plate 9 seals the sampling tank 1, the block 11 is inserted into the card slot 12. Through the mutual cooperation between the block 11 and the card slot 12, the cover plate 9 and the sampling tank 1 can be stably connected.

[0020] The lower end of the sealing block 10 is in an inverted cone shape, and the inverted cone shape of the sealing block 10 makes it easier for the sealing block 10 to enter the interior of the sampling tank 1 .

[0021] The lower end of the sampling tank 1 is in an inverted cone shape.

[0022] An anti-slip cover 13 is provided in the middle of the grip bar 4 . The provision of the anti-slip cover 13 effectively increases the friction between the palm and the grip bar 4 .

[0023] The outer side of the fixing rod 6 is provided with anti-skid patterns 14 , and the provision of the anti-skid patterns 14 effectively increases the friction between the palm and the fixing rod 6 .

[0024] Specifically, in the utility model, when sampling the slurry, the sampling tank 1 is inserted into the slurry, and the fixing rod 6 is pulled. The fixing rod 6 drives the second connecting rod 8 and the cover plate 9 to move in the vertical direction, so that the cover plate 9 is separated from the sealing block 10. At this time, the slurry can enter the sampling tank 1 through the opening at the upper end of the sampling tank 1. When the fixing rod 6 is not applied, the sleeve 5 moves on the first connecting rod 2 under the action of the elastic force of the spring 7. Through the transmission of the fixing rod 6 and the second connecting rod 8, the cover plate 9 and the sealing block 10 can automatically seal the sampling tank 1. When the cover plate 9 seals the sampling tank 1, the card block 11 is inserted into the card slot 12. Through the mutual cooperation between the card block 11 and the card slot 12, the cover plate 9 and the sampling tank 1 can be stably connected. The setting of the pin shaft 3 enables the sampling tank 1 to rotate around the first connecting rod 2, so that after the slurry sampling is completed, it is easier to pour out the slurry in the sampling tank 1.
