Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a pre-precipitation treatment device for wastewater from underground phosphate mining. Background Art

[0002] Phosphate mining will cause water pollution. In order to treat the sewage, sedimentation is first used to treat the large particles and broken stones in the sewage, and then the sewage is treated subsequently. During the sedimentation treatment, the precipitated materials will sink to the bottom of the device. In order to ensure the continuous sedimentation, the device needs to be cleaned and the precipitated materials at the bottom need to be cleaned and treated. The existing sedimentation treatment devices generally use sedimentation tanks for treatment. The sedimentation tanks have a certain depth, which makes it difficult to remove the sediment. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4The pre-sedimentation treatment device for underground phosphate mining wastewater includes a bottom plate 13, on which a sedimentation tank 1 is fixedly connected, and an inlet and an outlet are arranged at the upper end of the sedimentation tank 1. Water flows out from the inlet and the outlet to play a sedimentation role.

[0021] A movable plate 8 is abutted against the inner wall of the sedimentation tank 1, and a fixed plate 3 is fixedly connected to the movable plate 8. A hydraulic rod 9 is connected to the fixed plate 3 through a connecting mechanism. The lower end of the hydraulic rod 9 is moved by the movable mechanism. The hydraulic rod 9 is extended to drive the movable plate 8 to move. Since the sediment is on the movable plate 8, the movable plate 8 is moved out, thereby facilitating the cleaning of the sediment in the device.

[0022] The moving mechanism includes a slide 12, which is opened on a bottom plate 13. A slider 10 is slidably arranged in the slide 12, and the slider 10 is fixedly connected to a hydraulic rod 9. A threaded rod 11 is rotatably connected in the slide 12 through a bearing, and the threaded rod 11 threads through the slider 10. A motor 5 is fixedly installed on the bottom plate 13, and the motor 5 is transmission-connected to the threaded rod 11. The threaded rod 11 is driven to rotate by rotating the motor 5, thereby driving the slider 10 to slide in the slide 12, thereby moving the movable plate 8 and offsetting it above the sedimentation tank 1, so that the sediment can be scraped off by tools later.

[0023] Example 2

[0024] In Example 1, since the movable plate 8 is arranged horizontally, it is difficult to clean the sediment on the movable plate 8. Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, the connecting mechanism includes a fixed frame 6, the fixed frame 6 is fixedly connected to the hydraulic rod 9, the fixed frame 6 is rotatably connected to the rotating shaft 7 through a bearing, one end of the rotating shaft 7 is fixedly connected to the fixed plate 3, and the other end is fixedly connected to the gear 17, the gear 17 is fixed by the fixing mechanism, and the fixing mechanism is released to fix the gear 17, so that the movable plate 8 can rotate, so that the movable plate 8 has an inclination, so that under the action of gravity, the sediment slides down, and the sediment is convenient to clean.

[0025] The fixing mechanism includes a threaded sleeve 14, which is rotatably connected to the fixing frame 6 through a bearing. A threaded column 15 is connected to the inner thread of the threaded sleeve 14, and a rack 18 is fixedly connected to the threaded column 15. The rack 18 is meshed with the gear 17. A limiting mechanism is provided on the threaded column 15. By rotating the threaded sleeve 14, the position of the threaded column 15 in the threaded sleeve 14 is adjusted to drive the rack 18 to move, thereby driving the gear 17 to rotate, driving the movable plate 8 to rotate, and causing the movable plate 8 to tilt.

[0026] The limiting mechanism includes a positioning rod 16, which is fixedly connected to the fixing frame 6. A connecting sleeve 19 is fixedly connected to the threaded column 15. The positioning rod 16 passes through the connecting sleeve 19. By adopting the design of the positioning rod 16 and the connecting sleeve 19, the threaded column 15 is limited, thereby preventing the threaded column 15 from rotating, so that the threaded column 15 can only move in the up and down directions.

[0027] When cleaning, the hydraulic rod 9 is extended to drive the movable plate 8 to move, and the movable plate 8 is moved out. Then, the threaded sleeve 14 is rotated to adjust the position of the threaded column 15 in the threaded sleeve 14, and the rack 18 is driven to move, thereby driving the gear 17 to rotate, and driving the movable plate 8 to rotate, so that the movable plate 8 is tilted, and finally the sediment on the movable plate 8 is cleaned.

[0028] Example 3

[0029] Reference Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 2, a collecting box 2 is placed on the bottom plate 13, and the collecting box 2 is used so as to be placed below the inclined end of the moving plate 8 to collect the sediment.

[0030] A drain valve 4 is connected to the sedimentation tank 1. The drain valve 4 is designed so that when the sedimentation tank 1 needs to be cleaned, the drain valve 4 can be opened to drain the water.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
