DETAILED DESCRIPTION

[0018] See also Figure 1-4As shown, an embodiment of the present application provides a technical solution: a phosphogypsum water-stabilizing layer base mixing device, comprising a box body 21 with a feed port and a discharge port, a stirring device 3 arranged to rotate horizontally at the lower part of the box body 21, and a screening mechanism 4 arranged above the stirring device 3. The stirring device 3 includes a rotating shaft 31, a stirring blade 32 arranged on the rotating shaft 31, and cams 33 are provided 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 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 body 21. A controller is also provided in the system, and the controller controls the discharge valve 28 to discharge the material according to the signal of the photoelectric sensor 22.

[0019] Because the photoelectric sensor 22 is set below the cam 33, when the material height reaches the detection position of the photoelectric sensor 22, the controller controls the discharge valve 28 to open and discharge the material. In this way, the material height in the box 21 cannot be piled up to the position of the cam 33, and the material has no effect on the movement of the cam, which plays a role in protecting the equipment.

[0020] In a preferred solution, the photoelectric sensor 22 is arranged outside the box body 21 , an opening 211 is provided at a corresponding position of the side wall of the box body 21 , a transparent plate 23 is provided at the opening 211 , and the light of the photoelectric sensor 22 passes through the transparent plate 23 to detect the material.

[0021] The photoelectric sensor 22 may be a diffuse reflection sensor, and the transparent plate 23 may be made of glass or organic glass.

[0022] In the preferred embodiment, the stirring device 3 also includes bearing seats 34 arranged on both sides of the rotating shaft 31, a first sprocket 35 is provided on the side of the rotating shaft 31 extending out of the bearing seat 34, a support frame 36 is provided on the outside of the box body 21, a motor 37 is provided on the support frame 36, and a second sprocket 38 is provided on the output shaft of the motor 37. The motor 37 drives the stirring blade 32 to stir by setting a chain between the second sprocket 38 and the first sprocket 35.

[0023] In the preferred embodiment, the screening mechanism 4 includes a screen plate 41, which is provided with a first guide hole 411 and a second guide hole 412. A guide shaft 43 installed on the side wall of the box body 21 is provided in the first guide hole 411, and springs 44 are provided on part of the guide shaft 43 on the upper and lower sides of the screen plate 41. The sliding rod 42 is inserted into the second guide hole 412; a boss 45 is provided on the sliding rod 42 below the second guide hole 412.

[0024] The function of the boss 45 is to facilitate the upward movement of the sliding rod 42 so that the sieve plate 41 can be driven to move upward. When the sliding rod 42 moves downward, the sieve plate 41 moves along the guide shaft 43, compressing the spring, thereby vibrating the material under the action of the spring.

[0025] In the preferred solution, a feed barrel 24 is provided at the feed port; a porous plate 25 is connected to the bottom of the feed barrel 24; a horizontal plate 26 is fixed on the sliding rod 42, and a pin 27 matching the hole position on the porous plate 25 is provided on the horizontal plate 26.

[0026] The pin 27 is inserted into the hole of the porous plate 25 when it moves upward, and exits the hole of the porous plate 25 when it moves downward, so that the material in the feeding barrel 24 can be easily discharged into the box body 21.

[0027] In a preferred solution, a bracket 29 is further provided below the box body 21 .
