DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] A phosphogypsum conveying and drying device comprises a belt conveyor 1, brackets 9 are fixedly installed on both sides of the frame of the belt conveyor 1, a cover 3 is arranged on the bracket 9, the two ends of the cover 3 are connected to the feed pipe 2 and the exhaust pipe 6 respectively, an air intake main pipe 4 is arranged above the cover 3, and a plurality of air intake branch pipes 5 are connected to the air intake main pipe 4, the air intake branch pipe 5 is an L-shaped structure composed of a horizontal section 57 and a vertical section 51, the horizontal section 57 is arranged on the conveyor belt 11 in the belt conveyor 1, the horizontal section 57 is parallel to the conveying direction of the belt conveyor 1, the vertical section 51 passes through the cover 3 and is connected to the air intake main pipe 4, and a plurality of first exhaust holes 56 are opened on both sides of the horizontal section 57. The exhaust pipe 6 is connected to the cyclone dust collector and the bag dust collector in sequence, and the cover 3 is connected to a cover 8 at one end close to the feed pipe 2, and the cover 8 is used to block the channel between one end of the cover 3 and the conveyor belt 11 of the belt conveyor 1. The air intake main pipe 4 is connected to a hot air blower or a hot air furnace.

[0020] When in use, the phosphogypsum is put into the belt conveyor 1 through the feed pipe 2, and the belt conveyor 1 transports the phosphogypsum. During the transportation process, the hot air blower sends the hot air into the air intake main pipe 4, and the hot air is discharged from the first exhaust holes 56 on both sides of the horizontal section 57. The exhausted hot air enters the phosphogypsum in the transportation process, and the hot air takes away the moisture in the phosphogypsum, so that the phosphogypsum is dried. Finally, the hot air is discharged from the exhaust pipe 6, thereby realizing the transportation and drying of the phosphogypsum.

[0021] The horizontal section 57 is connected to an air supply pipe 54 , to which a material guide inclined plate 52 is fixedly connected. The material guide inclined plate 52 is inclined downward toward one end of the feed pipe 2 , and a plurality of second exhaust holes 55 are provided on the air supply pipe 54 .

[0022] During the process of conveying phosphogypsum by the belt conveyor 1, while the phosphogypsum passes over the material guide inclined plate 52, the hot air discharged from the second exhaust hole 55 blows and dries the fallen phosphogypsum, and turns the phosphogypsum with the cooperation of the air inlet branch pipe 5, thereby achieving the effect of conveying, turning and drying the phosphogypsum, making the phosphogypsum dry more evenly.

[0023] A rubber plate 53 is fixedly connected to one end of the guide inclined plate 52 which is tilted downward, and the rubber plate 53 abuts against the surface of the conveyor belt 11 in the belt conveyor 1. The rubber plate 53 can facilitate shoveling of phosphogypsum while preventing the surface of the conveyor belt 11 from being scratched.

[0024] The sealing member 7 is fixedly connected to both sides of the housing 3, and the sealing member 7 includes a rubber sheet 71 fixedly connected to the housing 3, one side of the rubber sheet 71 is connected to a rubber strip 73 through an elastic sheet 72, and the lower end of the rubber sheet 71 and the rubber strip 73 are against the surface of the conveyor belt 11 of the belt conveyor 1. The elastic sheet 72 and the rubber strip 73 form a double elastic seal between the sealing member 7 and the conveyor belt 11, so as to prevent the heat and dust from escaping from the gap between the two sides of the housing 3 and the conveyor belt 11 during drying.

[0025] The contents described in the embodiments of this specification are merely an enumeration of the implementation forms of the utility model concept. The protection scope of the utility model should not be deemed to be limited to the specific forms described in the embodiments. The protection scope of the utility model also extends to equivalent technical means that can be thought of by those skilled in the art based on the concept of the utility model.
