Description

Technical Field

[0001] The utility model relates to the technical field of metal recycling, and particularly relates to a wet dust collection device for a precious metal waste incinerator. Background Technique

[0002] Precious metal waste refers to the waste containing high-value metals such as gold, silver, platinum, and palladium generated during industrial processing. Since these precious metals have high economic value, it is very necessary to incinerate these wastes through an incinerator and recover the precious metals therein. During the incineration process, the non-metallic components in the precious metal waste are oxidized and decomposed, while the precious metals remain in the incinerated ash. The role of the wet dust collection device is to capture the dust in the flue gas during the incineration process. These dusts may contain precious metal particles, and through wet dust collection, these precious metal particles can be effectively collected for subsequent purification and recovery.

The outer surface of the guide rod 1 701 is fixedly connected to the cam 2 704, the outer surface of the guide rod 2 702 is fixedly connected to the cam 1 703, and the auxiliary rod 705 is provided with a buffer spring 706. The guide rod 1 701 is externally transmission-connected to an anti-slip belt 1 707.

[0027] like Figures 1-4As shown, the right side of the workstation plate 1 5 is fixedly connected to the left side of the workstation plate 2 6, the structure of the workstation plate 1 5 is the same as that of the workstation plate 2 6, and the workstation plate 1 5 is opposite to the workstation plate 2 6, the spray pipe 13 is connected to the external water circulation device, the concave support frame 1 is connected to the fan 10 through the connecting pipe 11, the exhaust plate 12 is fixedly connected to the top of the fan 10, the guide rod 1 701 is rotatably connected in the groove 16, the guide rod 2 702 is rotatably connected in the groove 16, the cam 1 703 is overlapped with the filter screen 15, the cam 2 704 is overlapped with the filter screen 15, and the two auxiliary rods 705 are fixedly connected to the filter screen 15.

[0029] like Figure 5As shown in the figure, the push-pull structure 9 includes a first concave plate 901, a second concave plate 903, and a second motor 906. The first concave plate 901 is fixedly connected to the concave support frame 1, and the second concave plate 903 is fixedly connected to the concave support frame 1.

[0031] The present utility model provides a wet dust collection device for a precious metal waste incinerator, and the specific working principle is as follows:

[0032] This wet dust collection device transports the flue gas to the inside through the intake pipe 14, sprays water mist through the spray pipe 13 with the internal liquid by means of an external water circulation device, so that the dust in the flue gas is fully contacted with the water mist. The dust aggregates into larger particles under the wetting action of water and settles to the bottom of the dust collector under the action of gravity. Then, the intake pipe 14 inside the first station plate 5 filters the particulate matter in the flue gas, and the purified flue gas is transported to the fan 10 through the connecting pipe 11 at the top. Then, the fan 10 and the exhaust plate 12 discharge the purified flue gas. The sludge that has settled to the bottom is concentrated and dehydrated through the sludge treatment system to recover the precious metals therein. After the circulating water undergoes water quality treatment, it is continued to be used in the spraying system to achieve the recycling of water resources.

[0033] During the operation of the wet dust collection device, the motor 1 801 drives the turntable 802 to rotate. Since the turntable 802 is connected to the guide rod 2 702 through the anti-slip belt 2 803, the guide rod 2 702 will rotate synchronously with the turntable 802. And the guide rod 1 701 is connected to the guide rod 2 702 through the anti-slip belt 1 707, and the cam 1 703 and the cam 2 704 will rotate around the guide rod 2 702 and the guide rod 1 701 respectively. When the convex surfaces of the cam 1 703 and the cam 2 704 contact the filter screen 15, the filter screen 15 will move upward in the groove 16. On the contrary, when the concave surfaces contact the filter screen 15, the filter screen 15 will move downward in the groove 16. And after the auxiliary rod 705 above the filter screen 15 moves in the chute 17, it will drive the buffer spring 706 to deform, so that the filter screen 15 can vibrate in the working plate 1 5 and shake off the dust on the surface.

[0034] When it is necessary to repair the working plate 1 5 in the concave support frame 1, the motor 2 906 can be used to drive the threaded rod 1 902 to rotate. The threaded rod 1 902 is connected to the threaded rod 2 904 through the anti-slip belt 3 905, so that the threaded rod 1 902 and the threaded rod 2 904 can rotate synchronously. And the working plate 1 5 and the working plate 2 6 will move on the surfaces of the threaded rod 1 902 and the threaded rod 2 904. After the working plate 1 5 and the working plate 2 6 move, their positions will be replaced, which is convenient for subsequent maintenance of the filter screen 15 in the working plate 1 5.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
