[0020] Example

[0021] Please refer to Figure 1The present embodiment provides a dust salt collection and utilization device, which includes a fluidized drying bed 1, a centrifugal negative pressure salt collection device and a salt storage bagging device. Specifically, the centrifugal negative pressure salt collection device includes a cyclone separator 21 and an induced draft fan 22. The air inlet of the cyclone separator 21 is connected to the air outlet of the fluidized drying bed 1, and the air outlet of the cyclone separator 21 is connected to the air inlet of the induced draft fan 22. The exhaust port of the induced draft fan 22 is provided with a wet dust collector 24. When in use, due to the operation of the induced draft fan 22, a negative pressure is formed inside the cyclone separator 21. The positive pressure and high temperature airflow in the fluidized drying bed 1 brings the dust salt into the negative pressure cyclone separator 21. The dust salt rotates and settles in the cyclone separator 21. The airflow and part of the remaining dust salt (less) enter the wet dust collector 24 through the induced draft fan 22 to remove all the dust salt and finally discharge the air. A first screw conveyor 23 is provided at the discharge port of the cyclone separator 21 for conveying the dusty salt collected by the cyclone separator 21, and the first screw conveyor 23 is a double discharge port structure, that is, two salt discharge ports are provided, one of which is connected to the water pool 3, and the other is connected to the salt storage bagging device. If the dusty salt in the cyclone separator 21 does not need to be packaged and utilized, the dusty salt is conveyed into the water pool 3 for dissolution by the first screw conveyor 23, and then sent to the evaporation tank for further evaporation and crystallization; if the dusty salt in the cyclone separator 21 needs to be utilized, the dusty salt is conveyed to the salt storage bagging device for weighing and bagging by the first screw conveyor 23.

[0022] It should be noted that, since the dust salt settled in the cyclone separator 21 is easy to adhere to and accumulate on the wall, the present embodiment provides a magnetic vibrator 211 in the cyclone separator 21 to prevent the dust salt from adhering to and accumulating on the wall.

[0023] In this embodiment, the salt storage bagging device includes a salt storage tank 41 and a second screw conveyor 42. The salt storage tank 41 is connected to the second screw conveyor 42, and the second screw conveyor 42 is provided with a weighing and packaging machine 43 for weighing and bagging dust salt. This weighing and packaging machine 43 adopts the existing technology, such as the "computer packing scale" of Luoyaoxing Grain Machinery on the 1688 platform. When in use, the bag clamping structure of the computer packing scale is used to clamp the packaging bag, and then the dust salt is filled into the bag. The weighing detection is performed while filling. When the weighing value reaches the preset value, the weighing and packaging machine 43 stops filling, and finally the bagged dust salt is sent to the next process through the conveyor belt. It should be noted that the weighing and packaging machine 43 is an existing technology, and its specific structure is not repeated here.

[0024] This embodiment collects the dust salt from the fluidized drying bed 1, and keeps the collected dust salt in a closed space until it enters the water pool 3 to be dissolved or packaged into bags. This embodiment automates, closes, and secures the transportation, storage, and packaging processes of the dust salt collected in the centrifugal negative pressure salt collection device, and can automatically recycle and process the dust salt efficiently and safely, reducing the labor intensity of workers and the operating costs of the enterprise, and eliminating the safety threats caused by the dispersion of dust salt.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
