Technical Field

[0001] The utility model relates to a phosphogypsum powder feeding device, belonging to the technical field of phosphogypsum powder feeding equipment. Background Art

[0002] With the continuous advancement of highway construction technology, a phosphogypsum water-stabilized material is now produced by mixing phosphogypsum powder with a certain proportion of cement powder, external additives and water. The phosphogypsum water-stabilized material has the advantages of high flexural and compressive strength, long setting time, good antifreeze performance, etc. It is very popular in the market when used in road construction materials.

[0003] Existing phosphogypsum water-stabilizing materials are all produced by continuous breaking production equipment. In the continuous production process of phosphogypsum water-stabilizing materials, phosphogypsum powder is usually automatically weighed and discharged by a proportioning machine. Due to the low density of phosphogypsum powder, it is easy to attach to the wall or agglomerate when it is discharged, which can easily lead to blockage of the discharge port of the proportioning machine, making it impossible for the phosphogypsum powder to fall onto the belt scale of the proportioning machine, thereby affecting the normal discharge operation; in order to solve the problem of blockage of the discharge port of the proportioning machine due to phosphogypsum powder attaching to the wall or agglomerating, existing staff usually use a long stick to insert the discharge port of the proportioning machine to clear it. This is not only troublesome to operate and has a high workload, but also has a poor effect on clearing the discharge port of the proportioning machine. The situation that the proportioning machine cannot discharge normally still exists, so it needs to be improved. Summary of the invention

[0004] The utility model aims to provide a phosphogypsum powder feeding device which reduces manual labor and solves the problem that the existing phosphogypsum powder is easy to adhere to the wall or agglomerate, which easily leads to the blockage of the proportioning feeding machine and the inability to feed the material normally.

[0010] The screening assembly includes a screening body, a rotating motor, a connecting rod and a reset spring. The screening body is a rectangular body. A plurality of reset springs are respectively installed between three side surfaces of the screening body and the inner wall of the storage hopper. A connecting rod is hinged on the other side surface of the screening body through a pin shaft. One end of the connecting rod passes through the storage hopper and extends to the outside.

[0024] An upper opening is provided at one end of the conveying cylinder, and a lower opening is provided at the other end of the conveying cylinder. A storage hopper 2 is installed on the conveying cylinder of the conveying auger 3 corresponding to the upper opening. The storage hopper 2 is funnel-shaped, and a discharge port is provided at the bottom of the storage hopper 2. The discharge port is connected with the upper opening of the conveying auger 3 to facilitate the smooth entry of the phosphogypsum powder from the storage hopper 2 into the conveying auger 3.

[0025] An end cover 5 is fixedly mounted on the top of the storage hopper 2 , and a feed port 6 is symmetrically arranged on the end cover 5 , and the feed port 6 is communicated with the interior of the storage hopper 2 .

[0026] A baffle 7 is movably inserted in the feed port 6, and one end of the baffle 7 extends to the outside of the end cover 5. Transverse push hydraulic cylinders 8 are fixedly installed on the end covers 5 on both sides of the feed port 6. The piston rod of the transverse push hydraulic cylinder 8 is fixedly connected to the baffle 7 extending to the outside of the end cover 5. When in use, the baffle 7 is moved to the left or right at the feed port 6 of the end cover 5 by extending or retracting the piston rod of the transverse push hydraulic cylinder 8, thereby realizing the opening or closing of the feed port 6.

[0027] A plurality of connecting plates 9 are fixedly installed below the baffle 7, on which a brush plate 10 is mounted, on which a plurality of bristles 11 are arranged, and the bristles 11 are in contact and connected with the screening component. When in use, when the baffle 7 moves to the left or right at the feed port 6 of the end cover 5, the brush plate 10 and the bristles 11 are synchronously driven to the left or right along the screening component, thereby rolling out the phosphogypsum powder on the screening component, increasing the screening area to increase the screening efficiency, and at the same time having a cleaning effect on the screening component.

[0028] A screening assembly is installed in the storage hopper 2, and the screening assembly includes a screening body, a rotating motor 12, a connecting rod 13 and a reset spring 14. The screening body is a rectangular body, and the screening body includes a screen frame 15, a screen mesh 16 and a clearance cylinder 17. The clearance cylinder 17 is fixedly installed at the center position of the screen frame 15 through a cross-shaped bracket. The inner diameter of the clearance cylinder 17 is larger than the diameter of the rotating shaft 20 of the scattering assembly. The purpose of such a setting is: the clearance cylinder 17 forms a clearance for the rotating shaft 20 of the scattering assembly to prevent the screening body from colliding with the rotating shaft 20, so as to ensure the normal screening.

[0029] A screen 16 is arranged between the yield cylinder 17 and the screen frame 15, and a plurality of return springs 14 are respectively installed between three side surfaces of the screen frame 15 of the screening body and the inner wall of the storage hopper 2. A connecting rod 13 is hinged on the other side surface of the screen frame 15, and one end of the connecting rod 13 passes through the storage hopper 2 and extends to the outside. A rotating motor 12 is fixedly installed on the storage hopper 2 corresponding to the connecting rod 13 through a motor mounting frame, and a turntable 21 is fixedly installed on the transmission shaft of the rotating motor 12. The turntable 21 is eccentrically hinged to the connecting rod 13. When in use, the turntable 21 is driven to rotate by the transmission shaft of the rotating motor 12, and the turntable 21 drives one end of the connecting rod 13 to move eccentrically, so that the connecting rod 13 forms a reciprocating swinging force on the screen frame 15. Since a plurality of return springs 14 are respectively installed between the screen frame 15 and the inner wall, the screen frame 15 swings back and forth to achieve cutting of phosphogypsum powder and reduce the agglomeration of phosphogypsum powder.

[0030] The storage hopper 2 below the screening component is equipped with a scattering component, which includes a scattering motor 22, a rotating shaft 20, a scattering cross bar 18 and a scattering blade 19. The rotating shaft 20 is movably mounted on the end cover 5, and a scattering motor 22 is fixedly mounted on the end cover 5 corresponding to one end of the rotating shaft 20. The transmission shaft of the scattering motor 22 is fixedly connected to the rotating shaft 20. A plurality of scattering cross bars 18 are fixedly mounted on the circumference of the rotating shaft 20. The scattering cross bars 18 are in a "T" shape. The purpose of such a setting is: through the "T"-shaped scattering cross bar 18, the area of ​​​​scattering phosphogypsum powder can be effectively increased, and at the same time, the scattering cross bar 18 can rotate smoothly in the storage hopper 2.

[0031] A plurality of scattering blades 19 are fixedly mounted on the rotating shaft 20 below the scattering cross bar 18 via a mounting rod, and the scattering blades 19 are in contact with and connected to the inner wall of the storage hopper 2. The purpose of such a setting is to scrape the inner wall of the storage hopper 2 by the scattering blades 19 during the scattering of the phosphogypsum powder, thereby effectively reducing the adhesion of the phosphogypsum powder to the wall.

[0032] A belt scale 4 is provided on the base 1 below one end of the conveying auger 3, and the lower opening of the conveying cylinder of the conveying auger 3 is arranged corresponding to the belt scale 4. When in use, the phosphogypsum powder output by the conveying auger 3 falls from the lower opening onto the belt scale 4, and is weighed by the belt scale 4 and transported to the next workstation.

[0033] When the phosphogypsum powder feeding device is used, firstly, a proper amount of phosphogypsum powder is poured into the storage hopper 2 from the feed port 6. Then, after the phosphogypsum powder is poured, the horizontal push hydraulic cylinder 8 is started, and the piston rod of the horizontal push hydraulic cylinder 8 is retracted, thereby driving the baffle plate 7 to move along the feed port 6 toward the direction of the scattering motor 22. During the movement, the baffle plate 7 drives the brush plate 10 to move synchronously, and the bristles 11 on the brush plate 10 move synchronously along the screen 16 to flatten the phosphogypsum powder on the screen 16 to increase the screening area of ​​the phosphogypsum powder on the screen 16. When the baffle plate 7 closes the feed port 6, the rotating motor 12 is started. The rotating motor 12 drives the screen frame 15 and the screen 16 to swing back and forth through the cooperation of the turntable 21, the connecting rod 13 and the reset spring 14, thereby realizing For the screening operation of the phosphogypsum powder, since the screen 16 has a certain impact and cutting effect on the phosphogypsum powder when it swings back and forth, the compaction phenomenon of the phosphogypsum powder is reduced, and the phosphogypsum powder after screening falls into the storage hopper 2, and the scattering motor 22 is started. The scattering motor 22 drives the rotating shaft 20, the scattering cross bar 18 and the scattering blades 19 to rotate synchronously, thereby further reducing the wall attachment or compaction phenomenon of the phosphogypsum powder after screening in the storage hopper 2. The phosphogypsum powder in the storage hopper 2 enters the conveying auger 3 through the discharge port, and the conveying auger 3 is started. Under the output action of the conveying auger 3, the phosphogypsum powder falls from the lower opening onto the belt scale 4, is weighed by the belt scale 4, and is conveyed to the next workstation, thereby completing the phosphogypsum powder unloading operation.

[0034] The phosphogypsum powder feeding device effectively reduces manual labor, solves the problem that the existing phosphogypsum powder is easy to adhere to the wall or agglomerate, which easily leads to blockage of the proportioning feeding machine and inability to feed normally, and is very suitable for use in continuous mixing equipment of phosphogypsum water-stabilized materials.
