Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum transportation technology, specifically a dust prevention device for phosphogypsum transportation and loading / unloading. Background Technology

[0002] Phosphogypsum is an industrial byproduct, whose main component is calcium sulfate dihydrate. It is produced during the production of phosphate compound fertilizer. After purification, calcination and modification, phosphogypsum can be used to produce gypsum building materials.

[0003] Currently, in the short-distance transportation of phosphogypsum using traditional dump trucks, the open top of the loading compartment inevitably leads to spillage and dust pollution due to road bumps. Using fully enclosed trucks for short-distance transport is uneconomical. Furthermore, dust is generated during loading and unloading. Therefore, these methods do not meet current requirements. To address this, we propose a dust control device for phosphogypsum transportation and loading / unloading. Utility Model Content

[0013] 1. This utility model, by incorporating a transmission mechanism and a dust suppression mechanism, allows for the operation of a first motor and a first water pump during the loading of phosphogypsum. The first water pump activates, and the first atomizing nozzle sprays fine water mist for dust suppression. Simultaneously, the first motor drives a crossbar to rotate, causing multiple active bevel gears to rotate, which in turn drive multiple driven bevel gears to rotate, thus rotating the connecting shaft and the dust suppression mechanism and increasing the dust suppression range. Furthermore, by incorporating a second atomizing nozzle, a discharge pipe, and an outer casing, the outer casing is first stretched by the handle during unloading of the phosphogypsum, extending the discharge pipe and reducing the discharge height, thereby minimizing dust. Then, the second water pump is activated, causing the second atomizing nozzle to spray fine water mist around the discharge pipe, preventing dust generation during unloading. This utility model eliminates dust generation during loading and unloading, reducing environmental pollution.

[0014] 2. This utility model is equipped with a moving mechanism and a tarpaulin. After loading is completed, the switch of the second motor is turned on. The second motor can drive the threaded rod to rotate. The threaded plate can move on the outer surface of the threaded rod, causing the tarpaulin to extend inside the groove.

When the first water pump 5 is working, the first atomizing nozzles 203 can spray out fine water mist.

[0025] The transmission mechanism 9 includes a crossbar 902, which is installed at the front and rear of the housing 1 through a transmission cavity 906.

[0029] Working Principle: When using this phosphogypsum transportation and loading / unloading dust suppression device, the container 1 is first loaded onto the truck bed via the mounting plate. Equipped with a transmission mechanism 9 and a dust suppression mechanism 2, during loading of the phosphogypsum, the first motor 901 and the first water pump 5 are switched on. The first water pump 5 operates, and the first atomizing nozzle 203 sprays fine water mist for dust suppression. Simultaneously, the first motor 901 drives the crossbar 902 to rotate, causing multiple active bevel gears 905 to rotate, which in turn drives multiple driven bevel gears 904 to rotate, thus rotating the connecting shaft 903 and the dust suppression mechanism 2, increasing the dust suppression range. Equipped with a moving mechanism 3 and a tarpaulin 4, after loading is complete, the second motor is switched on. The second motor drives the threaded rod 302 to rotate, and the threaded plate 303 can rotate on the threaded rod. The outer surface of 302 moves, causing the tarpaulin 4 to extend inside the groove 18. The other end of the tarpaulin 4 is inserted into the inner side of the slot, covering the groove 18. The box 1 and the tarpaulin 4 are connected to form a relatively sealed space, thereby avoiding dust generation during transportation. By setting a second atomizing nozzle 17, a discharge pipe 13, and an outer jacket 8, when unloading phosphogypsum, the outer jacket 8 is first stretched by the handle, and the discharge pipe 13 is extended, which can reduce the discharge height and thus reduce dust. Then, the switch of the second water pump 6 is turned on. The operation of the second water pump 6 can make the second atomizing nozzle 17 spray fine water mist to spray water around the discharge pipe 13, avoiding dust generation during unloading. This utility model does not generate dust during the loading, unloading, and transportation of phosphogypsum, minimizing dust pollution to the environment.
