Detailed Implementation

[0020] Please see Figures 1-6 As shown, this application provides a technical solution: a rapid feeding phosphogypsum water-stabilized base layer mixing device, including a box 21 with an inlet and an outlet, a horizontally rotating stirring device 3 located below the box 21, and a screening mechanism 4 located above the stirring device 3. The stirring device 3 includes a rotating shaft 31, stirring blades 32 on the rotating shaft 31, and cams 33 at both ends of the rotating shaft 31. The screening mechanism 4 includes a sliding rod 42 that moves on the surface of the cam 33. A feeding cylinder 24 is also provided at the inlet. A perforated plate 25 is connected to the bottom of the feeding cylinder 24. A horizontal plate 26 is also fixed on the sliding rod 42. Pins 27 that match the holes on the perforated plate 25 are provided on the horizontal plate 26. A spring vibration mechanism 5 is also provided on the horizontal plate 26. The spring vibration mechanism 5 is used to strike the bottom of the perforated plate 25 to facilitate the material in the feeding cylinder 24 falling onto the screening mechanism 4.

[0021] The principle of the spring vibration mechanism 5 is that when the pin 27 is inserted into the perforated plate 25, the spring vibration mechanism 5 is compressed at the same time. When the pin 27 retracts downward, the spring vibration mechanism 5 reciprocates under the action of the spring, thereby striking the bottom of the perforated plate 25, making it easier for the material in the feed cylinder 24 to fall onto the screening mechanism 4 below.

[0022] In a preferred embodiment, the spring vibration mechanism includes a first spring 51 disposed on the horizontal plate 26 and a striking block 52 disposed above the first spring 51.

[0023] The striking block 52 can be made of plastic to reduce the resistance of the spring after compression and rebound. In a preferred embodiment, a photoelectric sensor 22 is provided below the stirring device 3, and a discharge valve 28 is provided at the discharge port. The photoelectric sensor 22 is used to detect the height of the material inside the box 21. A controller is also provided in the system. The controller controls the discharge valve 28 to discharge material according to the signal of the photoelectric sensor 22. The photoelectric sensor 22 is located on the outside of the box 21, and an opening 211 is provided at the corresponding position on the side wall of the box 21. A transparent plate 23 is provided at the opening 211. The light from the photoelectric sensor 22 passes through the transparent plate 23 to detect the material.

[0024] Because the photoelectric sensor 22 is arranged below the cam 33, when the material height reaches the detecting position of the photoelectric sensor 22, the controller controls the discharge valve 28 to open to discharge the material, so that the material height in the box 21 cannot be stacked to the position of the cam 33, and the material has no influence on the movement of the cam, thus playing a role of protecting the equipment.

[0025] The photoelectric sensor 22 can be a diffuse reflection type sensor, and the transparent plate 23 can be glass or organic glass.

[0026] In the preferred embodiment, the stirring device 3 further comprises bearing seats 34 arranged on both sides of the rotating shaft 31, a first chain wheel 35 arranged on the side of the rotating shaft 31 extending out of the bearing seat 34, a support frame 36 arranged on the outside of the box 21, a motor 37 arranged on the support frame 36, and a second chain wheel 38 arranged on the output shaft of the motor 37, wherein the motor 37 drives the stirring blade 32 to stir through the chain arranged between the second chain wheel 38 and the first chain wheel 35.

[0027] In the preferred embodiment, the screening mechanism 4 comprises a screening plate 41, a first guide hole 411 and a second guide hole 412 arranged on the screening plate 41, a guide shaft 43 arranged on the side wall of the box 21 in the first guide hole 411, a second spring 44 arranged on the guide shaft 43 on the upper and lower sides of the screening plate 41, and a sliding rod 42 sleeved in the second guide hole 412.

[0028] The fixed ring 45 is arranged on the sliding rod 42 and has a hole in the inside, a notch beside the hole, and a screw arranged on one side of the fixed ring 45 to lock the position of the fixed ring 45, so as to conveniently move the position of the fixed ring 45 and adjust the compression degree of the spring of the screening plate 41, thus allowing the screening plate 41 to discharge within a suitable vibration range.

[0029] The fixed ring 45 is arranged on the sliding rod 42 and has a hole in the inside, a notch beside the hole, and a screw arranged on one side of the fixed ring 45 to lock the position of the fixed ring 45, so as to conveniently move the position of the fixed ring 45 and adjust the compression degree of the spring of the screening plate 41, thus allowing the screening plate 41 to discharge within a suitable vibration range.

[0030] The pin 27 is inserted into the hole of the multi-hole plate 25 when moving upward and is withdrawn from the hole of the multi-hole plate 25 when moving downward, thus conveniently discharging the material in the feeding cylinder 24 into the box 21.

[0031] In the preferred embodiment, a support 29 is further arranged below the box 21.
