Detailed implementation mode
[0019] The following further describes the present utility model in conjunction with the accompanying drawings and specific implementation modes.
[0020] Please refer to Figure 1-6 , the present utility model provides a technical solution: a raw material crushing device for phosphogypsum processing, including a housing 1, a hammer plate 12 rotatably arranged inside the housing 1, and a feed pipe 2 assembled on one side of the housing 1. Belt pulleys 11 are installed at both ends of the hammer plate 12 extending out of the housing 1, and a chassis 10 is installed at the bottom of the housing 1; a flip cover 5 is rotatably connected to the top of the housing 1 through a hinge 17, and an electric push rod 8 is connected between the rear end of the flip cover 5 and the chassis 10. A number of counterattack mechanisms 7 are assembled inside the flip cover 5, a latch 6 is installed at the end of the flip cover 5, and a clamping seat 3 adapted to the latch 6 is installed at the top of the feed pipe 2. Inner brackets 13 are installed at both ends inside the housing 1 at the bottom of the hammer plate 12. An arc-shaped groove 14 is opened on the inner side of the inner bracket 13, and a grate plate 15 is slidably installed inside the arc-shaped groove 14. One side of the grate plate 15 is connected to the inner bracket 13 through a bolt 16.
[0021] Based on the above structure settings, the raw material crushing device for phosphogypsum processing consists of a housing 1, a hammer plate 12 rotatably mounted inside the housing 1, and a feed pipe 2 assembled on one side of the housing 1. Among them, phosphogypsum is put into the interior of the housing 1 through the feed pipe 2. Both ends of the hammer plate 12 are rotatably connected to the housing 1. During the rotation process, the impact hammers carried on the hammer plate 12 are used to crush the phosphogypsum entering the interior of the housing 1. Specifically, during the working process, after the pulley 11 is connected to an external power device by a belt, driven by the external power device, the hammer plate 12 is driven to rotate by the pulley 11. After the phosphogypsum enters the interior of the housing 1 through the feed pipe 2, the hammer plate 12 cooperates with the counterattack mechanism 7 to achieve the crushing treatment of the phosphogypsum. The crushed phosphogypsum is screened by the grate plate 15. The unpassed phosphogypsum continues to stay inside the housing 1 for processing. The phosphogypsum screened by the grate plate 15 is discharged from the bottom of the housing 1. When the device is under maintenance, the hammer plate 12 stops running, and the electric push rod 8 starts to contract. During the contraction process, the flip cover 5 is driven to flip around the hinge 17, so that the flip cover 5 is separated from the overlapping state with the housing 1, facilitating the maintenance of the counterattack mechanism 7 and the hammer plate 12 assembled on the flip cover 5 and the housing 1. By removing the bolt 16 and then removing the grate plate 15 from the inner support 13 along the arc groove 14, it is convenient for the user to repair and maintain the grate plate 15. After the spare grate plate 15 is reinstalled between the inner supports 13 along the arc groove 14, the bolt 16 is passed through the grate plate 15 and connected to the inner support 13 to limit the position of the grate plate 15. This raw material crushing device for phosphogypsum processing is equipped with a rotatable flip cover 5 on the housing 1, which can make it more convenient for the user to repair and replace the counterattack mechanism 7 and the hammer plate 12 assembled inside during use. By designing the grate plate 15 to be a structure that is convenient for replacement and removal, it is possible for the user to replace the grate plates 15 with different screening densities according to different processing requirements, optimizing the use process.
[0022] Furthermore, the counterattack mechanism 7 includes a counterattack frame 701 and an adjusting bolt 702. The counterattack frame 701 is distributed around the interior of the flip cover 5, and the top of the counterattack frame 701 is rotatably connected to an adjusting bolt 702 extending out of the flip cover 5. The adjusting bolt 702 is threadedly connected to the flip cover 5. Among them, the counterattack frame 701 is used to assist in impact crushing of the phosphogypsum flying at high speed. By rotating the adjusting bolt 702 during use, the distance between the counterattack frame 701 and the hammer plate 12 can be controlled.
[0023] Furthermore, the counterattack mechanism 7 further includes a guide rod 703, and the guide rods 703 are installed on the tops of the guide rods 703 at both ends of the adjusting bolt 702, and the ends of the guide rods 703 penetrate the flip cover 5. Among them, the guide rods 703 can guide the moving trajectory of the counterattack frame 701 when in use, so as to prevent the counterattack frame 701 from rotating under the drive of the adjusting bolt 702.
[0024] Furthermore, both ends of the electric push rod 8 are rotatably connected to the connection seat 9, and the connection seat 9 is respectively fixedly connected to the flip cover 5 and the base frame 10. Among them, the angle formed between the electric push rod 8 and the flip cover 5 and the base frame 10 will change during operation, and the angle adjustment is satisfied by the connection seat 9.
[0025] Furthermore, the limiting rod 4 is slidably installed inside the clamping block 6, and the edge of the limiting rod 4 contacts the clamping seat 3. The distance between the axis of the limiting rod 4 and the hinge 17 is smaller than the distance between the highest point of the clamping seat 3 and the hinge 17. When the limiting rod 4 is not removed from the inside of the clamping block 6, the clamping block 6 cannot be driven to separate from the inside of the clamping seat 3 during the rotation of the flip cover 5, so it cannot be opened, thereby increasing the tightness between the flip cover 5 and the housing 1.
[0026] Furthermore, a through hole is provided at the bottom of the shell 1, and a discharge port 18 is provided inside the base frame 10. The through hole and the discharge port 18 can be used to discharge the processed phosphogypsum from the bottom of the shell 1 during use, so as to facilitate centralized collection.
[0027] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
