[0002] Sludge treatment is a processing process of concentrating, conditioning, dewatering, stabilizing, drying or incinerating sludge to reduce its quantity, stabilize it and make it harmless. If sludge is directly discharged into the environment, it will cause serious pollution to the environment. In order to control environmental pollution, corresponding process treatment needs to be carried out on the sludge, and then it needs to be concentrated and transported away, so a corresponding sludge discharging tank is required.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN216835860U discloses a sludge discharging tank for environmental pollution treatment, which includes a discharging hopper. The top end inside the discharging hopper is provided with a top plate, and the outer walls on both sides of the top plate are fixedly connected to the inner wall of the discharging hopper.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1-7, the present utility model provides a technical solution: an anti-adhesion sludge discharge chute, including a discharge chute 1. A fixing plate 2 is fixed at the top of the discharge chute 1. A rotating shaft 3 is rotatably installed at the center of the fixing plate 2 through a bearing. The upper end of the rotating shaft 3 is fixedly connected to the output end at the bottom of the motor 4. The outer wall of the motor 4 is fixed to the top of the fixing plate 2 through a mounting plate. A support plate 5 is fixed on the outer wall of the rotating shaft 3 above the discharge chute 1. A limiting groove 6 is opened on one side of the support plate 5 close to the inner wall of the discharge chute 1. A movable plate 7 is slidably installed between the support plates 5. A limiting block 8 is fixed on the side of the movable plate 7. The limiting block 8 is slidably installed inside the limiting groove 6. A through groove 17 is opened on the inner side of the limiting groove 6. A lead screw 9 is fixed on the side of the limiting block 8. The end of the lead screw 9 passes through the inside of the through groove 17 and is threadedly installed with a nut 10. An anti-slip pad 11 is nested on the outer side of the lead screw 9. The anti-slip pad 11 is located between the support plate 5 and the nut 10. A rubber sheet 12 is fixed on the side of the movable plate 7 through a screw 13. The side of the rubber sheet 12 abuts against the inner side of the discharge chute 1.

[0026] Lifting lugs 14 are fixed on both sides of the top of the discharge chute 1, so that the discharge chute 1 can be lifted by a crane.

[0027] An outlet pipe 15 is arranged at the bottom of the discharge chute 1. An electromagnetic valve 16 is installed on the outlet pipe 15. The opening and closing of the outlet pipe 15 can be completed through the electromagnetic valve 16, so that the sludge inside the discharge chute 1 can be discharged through the outlet pipe 15.

[0028] Two nuts 10 are arranged on the lead screw 9, which increases the stability of the movable plate 7 fixed between the support plates 5.

[0029] A number of screws 13 are arranged on the rubber sheet 12. The screws 13 are threadedly connected to the movable plate 7 and penetrate through the rubber sheet 12, and the ends of the screws 13 are located inside the rubber sheet 12, so that the rubber sheet 12 can be stably fixed on the side of the movable plate 7 and the rubber sheet 12 can be detached and replaced with a new one.

[0030] Two limiting blocks 8 and lead screws 9 are symmetrically distributed about the central axis of the movable plate 7. The lead screw 9 and the through groove 17 form a sliding connection, so that both sides of the movable plate 7 can be fixed by the lead screw 9 and the nut 10, improving the stability of the movable plate 7 after fixation. The design of the limiting groove 6 and the limiting block 8 ensures that the movable plate 7 will not move left and right.

[0031] Working principle: When using this anti-adhesion sludge discharge chute, first pour the sludge into the discharge chute 1, then hang the hook on the crane on the lifting lug 14, transfer the discharge chute 1 to the designated position through the crane, and open the outlet pipe 15 by starting the electromagnetic valve 16, so that the sludge inside the discharge chute 1 is discharged through the outlet pipe 15;

[0032] Next, start the motor 4. At this time, the motor 4 drives the rotating shaft 3 and the two support plates 5 to rotate simultaneously. Then, the support plate 5 drives the movable plate 7 and the rubber sheet 12 to rotate, so that the rubber sheet 12 scrapes the sludge on the inner wall of the discharge chute 1. When the rubber sheet 12 is severely worn and needs to be disassembled and replaced, use a wrench to rotate the nut 10, so that the nut 10 moves away from the support plate 5, making the lead screw 9 out of the fixed state. Then, pull up the two lead screws 9. At this time, the lead screws 9 drive the limit block 8, the movable plate 7 and the rubber sheet 12 to be taken out from the inside of the discharge chute 1. Then, use a screwdriver to disassemble the screw 13, so that the rubber sheet 12 is taken off from the movable plate 7. Install the new rubber sheet 12 on the side of the movable plate 7 and fix it on the movable plate 7 through the screw 13. Then, pass the movable plate 7 through between the two support plates 5, insert the limit block 8 on the movable plate 7 into the limit groove 6, place the lead screw 9 into the through groove 17, and then by rotating the nut 10, fix the movable plate 7, the limit block 8 and the lead screw 9, so that the rubber sheet 12 is fixed. In summary, the disassembly and replacement of the movable plate 7 and the rubber sheet 12 are completed.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
