Description

Technical Field

[0001] The utility model relates to the technical field of phosphogypsum processing equipment, in particular to a waste residue processing device used in phosphogypsum production. Background Art

[0002] Phosphogypsum waste residue can be used as a raw material in cement production. This not only saves energy and reduces emissions, but also improves cement quality. Calcium phosphate and silicates in phosphogypsum waste residue react with minerals in cement to form new cement clinker, thereby increasing cement strength and durability. To meet the requirements of cement production processes, phosphogypsum waste residue requires screening.

[0003] Patent announcement number CN216094796U discloses a secondary screening device for lightweight gypsum production waste, including a screening box, a filter box, an air supply device, and a conveying pipe. The screening box is used to screen out weeds and paper scraps from the powder. The conveying pipe includes a horizontal pipe and an inclined pipe connected to each other. The end of the horizontal pipe is connected to the air outlet end of the air supply device. The discharge port of the screening box is connected to the side wall of the horizontal pipe. The filter box is tilted along the axis of the inclined pipe in the inclined pipe. The filter box is provided with a filter screen perpendicular to the axis of the inclined pipe. The bottom of the filter box is provided with a slag discharge port. The outlet end of the inclined pipe is connected to a storage tank, and the top of the storage tank is connected to a dust collector. This screening device only has a single screening function. For phosphogypsum containing larger particles or agglomerates, its screening effect is often unsatisfactory. It does not have the function of processing larger phosphogypsum, which leads to the problem of easy blockage during the screening process. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-5 The waste residue treatment device shown in the figure is used for the production of phosphogypsum, including a chassis 1, a second sieve plate 13 mounted inside the chassis 1, a vibration motor 2 installed on the top of the chassis 1, and a hopper 3 on one side of the top of the chassis 1, mounting frames 14 are installed on both sides of the chassis 1, and the top of the mounting frame 14 is connected to the second sieve plate 13 through a plurality of elastic connecting members 15; a first sieve plate 4 is installed inside the hopper 3, and an auxiliary box 5 connected to the chassis 1 is installed on the other side of the hopper 3, a second crushing roller 9 is rotatably installed inside the chassis 1 at the bottom of the auxiliary box 5, a first crushing roller 8 is rotatably installed inside the chassis 1 on the other side of the second sieve plate 13, a rocker arm 11 is rotatably installed inside the chassis 1 at the bottom of the second sieve plate 13, and an electric motor 12 is installed at both ends of the chassis 1, and the output end of the electric motor 12 is connected to the rocker arm 11.

[0022] Based on the above-mentioned structural setting, the waste residue treatment device for phosphogypsum production consists of a chassis 1, a second sieve plate 13 mounted inside the chassis 1, a vibration motor 2 installed on the top of the chassis 1, and a hopper 3 on one side of the top of the chassis 1. The chassis 1 is in an inclined state as a whole, and the phosphogypsum is guided into the interior of the chassis 1 through the hopper 3 and falls onto the second sieve plate 13. After the vibration motor 2 is started, the vibration is transmitted to the second sieve plate 13 through the chassis 1, and the phosphogypsum is screened by the second sieve plate 13. Specifically, During operation, after the phosphogypsum enters the hopper 3, the first sieve plate 4 is used to intercept the larger phosphogypsum. The intercepted phosphogypsum enters the auxiliary box 5 under the guidance of the first sieve plate 4. The second crushing roller 9 is used to squeeze and crush the phosphogypsum in the auxiliary box 5. The crushed phosphogypsum falls back onto the second sieve plate 13 for secondary screening. The phosphogypsum that passes the screening of the second sieve plate 13 falls to the bottom of the chassis 1, and the phosphogypsum that does not pass the screening of the second sieve plate 13 automatically slides down to the first crushing roller 8. During the operation, the first crushing roller 8 is used to crush the phosphogypsum. The processed phosphogypsum also falls to the bottom of the inside of the chassis 1 and is discharged from the inside of the chassis 1. The elastic connecting member 15 is composed of a telescopic rod and a spring. The two ends of the telescopic rod are respectively connected to the second screen plate 13 and the mounting frame 14. The spring is sleeved on the outer periphery of the telescopic rod. When the second screen plate 13 is blocked, the motor 12 is energized to drive the rocker arm 11 to rotate inside the chassis 1. During the rotation of the rocker arm 11, the bottom of the second screen plate 13 is hit, thereby avoiding the blockage of the second screen plate 13 when in use. The elastic connecting member 15 can automatically drive the second screen plate 13 to reset. The waste residue treatment device for phosphogypsum production has two sets of screen plates and crushing rollers installed on the chassis 1. When in use, the phosphogypsum entering the chassis 1 can be screened and the phosphogypsum that does not meet the screening requirements can be crushed. The sieve holes on the second screen plate 13 are prevented from being blocked by hitting the bottom of the second screen plate 13, thereby improving work efficiency.

[0023] Furthermore, a plurality of servo motors 7 are mounted on both sides of the chassis 1. The output ends of the servo motors 7 extend into the interior of the chassis 1 and are connected to a first crushing roller 8 and a second crushing roller 9. When the servo motors 7 are activated, they provide power to the first crushing roller 8 and the second crushing roller 9. The first crushing roller 8 and the second crushing roller 9 rotate to crush the phosphogypsum.

[0024] Furthermore, a guide platform 10 is installed on the other side of the chassis 1. There is a certain gap between the guide platform 10 and the second sieve plate 13, and the gap is located directly above the first crushing roller 8. When in use, the guide platform 10 is used to guide large particles on the second sieve plate 13.

[0025] Furthermore, a discharge port is provided on the other side of the chassis 1, and a guide plate 6 is installed on the other side of the chassis 1. The discharge port is used to discharge the phosphogypsum powder after screening inside the chassis 1, and the guide plate 6 is used to guide the discharge of the phosphogypsum during the discharge process.

[0026] Furthermore, bearings 18 are provided at both ends of the first crushing roller 8, the second crushing roller 9, and the rocker arm 11, and the bearings 18 are located inside the chassis 1. The bearings 18 can define the positions of the first crushing roller 8, the second crushing roller 9, and the rocker arm 11 inside the chassis 1 without affecting the rotation of the first crushing roller 8, the second crushing roller 9, and the rocker arm 11, thereby ensuring smoother operation of the first crushing roller 8, the second crushing roller 9, and the rocker arm 11.

[0027] Furthermore, a plurality of damping spring shock absorbers 17 are distributed at both ends of the bottom of the chassis 1, and a base 16 is installed at the bottom of the damping spring shock absorber 17. The base 16 can expand the contact area between the bottom of the damping spring shock absorber 17 and the ground, and the use of the damping spring shock absorber 17 can reduce the resonance caused by the vibration of the chassis 1, making the base 16 more stable.

[0028] The utility model can screen the phosphogypsum entering the interior of the chassis and crush the phosphogypsum that does not meet the screening requirements during operation, and is not prone to clogging during screening.

[0029] The embodiment described above is only a preferred solution of the present invention and does not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
