Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment equipment, and particularly relates to a sludge treatment device for a sewage treatment plant. Background Art

[0002] When a sewage treatment plant treats sewage, it will remove the sundries in the sewage. Some sundries will form sludge after being cleaned and precipitated. These sludges cannot be directly discharged, so they need to be treated. Basically, it is a drying treatment method. By removing the water in the sludge, making it dry and solidify, and then transporting it for subsequent treatment to reduce the impact of sludge on the environment.

[0003] The current sludge treatment is basically spiral pressing, plate and frame pressing, and centrifugation, etc. These methods can effectively remove the water in the sludge. However, for the plate and frame and centrifugal methods, the interval between each batch of sludge treatment is long and they cannot be continuously treated, so the applicable sewage treatment plants are limited. While the spiral can be continuously treated, but the discharged sludge is in pieces, which is not convenient for subsequent transportation. Therefore, a sludge treatment device for a sewage treatment plant is proposed. Summary of the Utility Model

[0004] The technical solution adopted by the utility model to solve the technical problems is: a sludge treatment device for a sewage treatment plant, including a turntable. The side wall of the top of the turntable is evenly and fixedly connected with treatment boxes. Through holes are all penetrated and opened at the positions on the side wall of the top of the turntable opposite to the treatment boxes. Filter meshes are inlaid in the through holes, and the filter meshes are inlaid and connected to the inner part of the bottom end of the treatment boxes. A pressing plate is arranged above the opening at the top of the treatment box, and a vertical telescopic rod is detachably connected to the middle of the side wall of the top of the pressing plate.

[0005] As a preferred technical solution of the utility model, an adapter column is detachably connected to one side wall of the vertical telescopic rod. A central column is fixedly connected to the middle of the side wall of the top of the turntable. One end of the adapter column far away from the vertical telescopic rod is fixedly connected to the side wall of the central column close to the top edge.

[0006] As a preferred technical solution of the utility model, a collecting conical column is rotatably connected to the bottom of the turntable. An extension plate is fixedly connected to the side wall of the collecting conical column close to the turntable. A motor is detachably connected to the top side wall of the extension plate far away from the turntable. Tooth teeth are fixedly connected to the outer wall of the turntable. A gear is detachably connected to the output end of the motor, and the gear is meshed with the tooth teeth on the turntable.

[0007] As a preferred technical solution of the utility model, the collecting conical column is of a conical structure. Vertical rods are evenly fixedly connected to the side wall of the collecting conical column close to the bottom end. A drain pipe is detachably connected to the bottom end of the collecting conical column. A conveyor belt is arranged on one side of the collecting conical column.

[0008] As a preferred technical solution of the present utility model, a closed door panel is rotatably connected to a side wall of the processing box close to the turntable. A small remote electronic lock is connected to the closed door panel.

Detailed Embodiment

[0014] The present utility model will be further described below with reference to the drawings.

[0015] Please refer to Figures 1-3, a sludge treatment device for sewage treatment plants of the present utility model, includes a turntable 1. The top side wall of the turntable 1 is evenly and fixedly connected with treatment boxes 2. The bottom of the turntable 1 is rotatably connected with a collecting conical column 8. One side wall of the collecting conical column 8 close to the turntable 1 is fixedly connected with an extension plate 9. The top side wall of the extension plate 9 far from the turntable 1 is detachably connected with a motor 10. The outer wall of the turntable 1 is fixedly connected with teeth. The output end of the motor 10 is detachably connected with a gear 11. The gear 11 is meshed with the teeth on the turntable 1. Above the top opening of the treatment box 2, a pressing plate 3 is provided. In the middle of the top side wall of the pressing plate 3, a vertical telescopic rod 4 is detachably connected;

[0016] One side wall of the vertical telescopic rod 4 is detachably connected with an adapter column 5. In the middle of the top side wall of the turntable 1, a central column 6 is fixedly connected. One end of the adapter column 5 far from the vertical telescopic rod 4 is fixedly connected to the side wall of the central column 6 near the top edge.

[0017] The technical effect of this solution is as follows: After the sludge is injected into the treatment box 2, the treatment box 2 containing the sludge is rotated away by the rotation of the turntable 1. The vertical telescopic rod 4 is started to drive the pressing plate 3 to descend. Since the space in the treatment box 2 is fixed, when the pressing plate 3 gradually descends, a large pressure will be applied to the sludge, causing it to gradually contract, thereby squeezing out the water contained in the sludge and realizing the function of sludge drying. After the extrusion and drying are completed, the horizontal telescopic rod 17 is started to drive the push plate 18 to push the dried sludge, and finally it is discharged from the opening connected to the closing door plate 16 and falls onto the conveyor belt 13 and sent to the next process. Through the rotating turntable 1, an efficient continuous treatment function is realized, and at the same time, the sludge can be compressed into blocks for subsequent transportation and treatment.

[0018] Through holes 14 are respectively and penetratingly opened on the top side wall of the turntable 1 and at positions opposite to the treatment boxes 2. Filter meshes 15 are embedded in the through holes 14. The filter meshes 15 are embedded and connected to the inner bottom end of the treatment boxes 2. The collecting conical column 8 is of a conical structure. The side wall of the collecting conical column 8 close to the bottom end is evenly and fixedly connected with vertical rods. A drain pipe 12 is detachably connected to the bottom end of the collecting conical column 8. A conveyor belt 13 is provided on one side of the collecting conical column 8. The side wall of the treatment box 2 close to the turntable 1 is rotatably connected with a closing door plate 16. A small remote electronic lock is connected to the closing door plate 16. A feed pipe 7 is provided above one side of the treatment box 2. The outlet of the feed pipe 7 corresponds to the top opening of the treatment box 2. A horizontal telescopic rod 17 is detachably connected to the side wall of the treatment box 2 far from the closing door plate 16 and close to the bottom. The output end of the horizontal telescopic rod 17 extends into the treatment box 2 and is detachably connected with a push plate 18. A heating pipe 19 is embedded in the side wall of the treatment box 2 above the horizontal telescopic rod 17.

[0019] The technical effects of this solution are as follows: The squeezed water will pass through the filter net 15, then through the through hole 14, and finally fall into the collection conical column 8 for collection. The water that enters the collection conical column 8 flows along the collection conical column 8 and finally enters the drain pipe 12. The functions of collecting and transporting the wastewater are realized through the collection conical column 8 and the drain pipe 12, avoiding the overflow of wastewater. By driving the gear 11 to rotate with the motor 10, the turntable 1 can be driven to rotate, thereby driving the treatment tank 2 to pass under the feed pipe 7 in turn, realizing the function of continuous treatment.

[0020] Specifically, when the present utility model is in use, the motor 10 is started to drive the turntable 1 to rotate via the gear 11. When a treatment tank 2 is moved under the feed pipe 7, the motor 10 stops running. At this time, the feed pipe 7 starts to inject materials. After the injection is completed, the motor 10 moves the corresponding treatment tank 2 away and moves the next treatment tank 2 under the feed pipe 7. The removed treatment tank 2 starts the corresponding vertical telescopic rod 4 to drive the pressing plate 3 to descend to compress the sludge. At the same time, the motor 10 repeats the above steps until the treatment tank 2 that was first injected is moved to the position corresponding to the conveyor belt 13. At this time, the sludge in the treatment tank 2 is also compressed. Then the horizontal telescopic rod 17 is started to drive the push plate 18 to push the formed sludge. The electronic lock on the pre-opened closing door plate 16 is unlocked. The closing door plate 16 is pushed open by the pushing, and finally the sludge is pushed onto the conveyor belt 13 for transportation. Then the closing door plate 16 returns to its original position under its own weight and the electronic lock locks it, entering the next treatment process, thereby realizing a high-performance continuous treatment process and making the sludge into blocks for easy transportation.

[0021] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
