[0016] like Figures 1 to 4 As shown, a phosphogypsum dust reduction unloading device comprises an unloading room 1 made of concrete, a vehicle entrance and exit are arranged on one side of the unloading room 1, a unloading pipe 9 is connected to one end of the top of the unloading room 1 near the entrance and exit, a track 2 is arranged on one side of the entrance and exit, and an electric telescopic push-pull shed 7 is installed on the track 2 (the tarpaulin covering the electric telescopic push-pull shed 7 is not drawn in the figure). When the unloading pipe 9 unloads the material into the truck bucket, the electric telescopic push-pull shed always covers the truck to prevent the outside wind from blowing the phosphogypsum powder, and at the same time prevent the phosphogypsum powder from escaping, preventing the dust from drifting to the factory area, and protecting the factory environment.
[0017] A plurality of drainage ditches 6 are arranged around the electric telescopic sliding shed 7, a water grate 5 is arranged on the drainage ditches 6, a spray pipe 3 is installed at one end of the electric telescopic sliding shed 7, a plurality of nozzles 4 are installed on the spray pipe 3, and the spray pipe 3 is connected to the tap water pipe through a hose. After the truck carrying the phosphogypsum leaves the electric telescopic sliding shed 7, tap water is sent into the spray pipe 3 and sprayed out from the nozzle 4 to reduce the dust of the flying phosphogypsum, and the dust-reduced water is discharged from the drainage ditch 6, thereby further preventing the phosphogypsum from raising dust and improving the dust reduction effect.
[0018] An electric valve 13 is installed on the spray pipe 3, and a discharger is installed on the feed pipe 9. The discharger and the electric valve 13 are connected to the output end of the controller. The electric valve 13 is used to automatically control the spray pipe 3, and the controller uses a TPC8-8TD timing program controller.
[0019] An audible and visual alarm 8 is installed on the unloading room 1, and a distance sensor 12 is provided in the unloading room 1. The distance sensor 12 is connected to the input end of the controller, and the audible and visual alarm 8 and the electric telescopic sliding shed 7 are connected to the output end of the controller. The distance sensor 12 is used to detect the position of the truck. When it is detected that the truck reaches the set position, the controller controls the audible and visual alarm 8 to start to remind the driver to stop or move.
[0020] A reversing pile 11 is provided in the unloading room 1 to prevent the truck from hitting the unloading room 1 when reversing.
[0021] The use process of the utility model is:
[0022] Initially, the electric telescopic sliding shed is in a retracted state, and the electric valve 13 is closed;
[0023] Step 1: The truck reverses into the unloading room 1. When the distance sensor 12 detects that the rear wheel of the truck is against the reversing pile 11, the sound and light alarm is activated for 85 seconds. At this time, the front of the truck is outside the electric telescopic sliding shed, and then the controller controls the unloader on the unloading pipe 9 to start, so as to load the phosphogypsum into the truck bucket.
[0024] Step 2: After 10 seconds, the first section of the truck bed is filled with phosphogypsum, and then the truck moves forward. At the same time, the distance measuring sensor 12 detects the distance the truck moves forward. When the moving distance of the truck reaches 2m, the sound and light alarm 8 is activated. The truck driver hears the sound and stops the truck. During the movement of the truck, the controller controls the electric telescopic sliding shed to extend outward along with the truck.
[0025] Step 3: After another 10 seconds, the second section of the truck bed is filled with phosphogypsum. According to the method in the second step above, the remaining section of the truck bed is loaded until the truck is filled with phosphogypsum.
[0026] Step 3: When the truck is fully loaded with phosphogypsum and walks out of the electric telescopic sliding shed, the electric telescopic sliding shed is just at the extreme extension position. Then the controller controls the electric valve 13 on the spray pipe 3 to start, allowing tap water to spray out from the nozzle 4 to spray and reduce the phosphogypsum dust at the outlet of the electric telescopic sliding shed.
[0027] Step 4: After 1 minute, the electric telescopic push-pull shed slowly retracts from the extreme extension position toward the lower material room 1. During the retraction process, the nozzle 4 continues to spray tap water until the electric pull-pull shed retracts to the initial state.
[0028] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
