[0030] Please refer to Figures 1-6, the present utility model provides a technical solution: a sludge pretreatment device based on sludge power generation, including a box body 1 and a driving motor 3, with one side surface of the box body 1 fixedly connected to the driving motor 3; a support plate 2 is fixedly connected to one side surface of the box body 1, and the top surface of the support plate 2 is fixedly connected to the driving motor 3. A feed inlet 4 is opened on one side of the top surface of the box body 1.

At the same time, the spiral conveyor paddle 5 is rotatably connected to the limit sleeve 6, and the pitch of the spiral conveyor paddle 5 gradually decreases from left to right. During the rotation of the spiral conveyor paddle 5, the extrusion force on the sludge will gradually increase with the decrease of the pitch, improving the dehydration efficiency of the sludge.

[0031] A roller 1205 is slidably connected to the top surface of the sliding plate 1202. Stable plates 1206 are rotatably connected to both sides of the roller 1205.

Through the movement of the sliding plate 1202, the rollers 1205 on the sliding plate 1202 descend along with the movement of the sliding plate 1202. At the same time, the descent of the rollers 1205 can drive the descent of the clamping rod 1207. Through the descent of the clamping rod 1207, the clamping rod 1207 is separated from the card slot 29, so that the filter plate 9 or the filter net 13 can be taken out, thereby improving work efficiency. At the same time, the limiting plate 1209 is fixedly connected to the connection box 1201, and the clamping rod 1207 is slidably connected to the limiting plate 1209.

[0032] A filter plate 9 is arranged inside the partition plate 8. A plurality of sliding grooves 10 are opened on both sides of the partition plate 8. Sliding blocks 11 are slidably connected inside the sliding grooves 10. The surface of one side of the sliding block 11 away from the sliding groove 10 is fixedly connected to the filter plate 9. A filter net 13 is slidably connected to one side of the top surface of the partition plate 8. A water collecting tank 14 is arranged below the partition plate 8. An outlet 15 is opened on one side surface of the box body 1 near the bottom. An inclined plate 16 is fixedly connected to one side surface of the water collecting tank 14. A scraping plate 17 is fixedly connected to one side surface of the bottom surface of the water collecting tank 14. As Figure 1 、 2 shown, the inclined plate 16 can make the dewatered sludge slowly fall onto the conveyor belt 23, and the scraping plate 17 can preliminarily flatten the sludge on the conveyor belt 23, so that the sludge can be better dried.

[0033] One side surface near the tail of the output end of the driving motor 3 is meshed with a belt 18. The bottom surface of the belt 18 is meshed with a reciprocating lead screw 19. A high-temperature steam pipe 20 is fixedly installed inside the box body 1. A plurality of nozzles 21 are connected through the bottom surface of the high-temperature steam pipe 20. One side surface of the high-temperature steam pipe 20 away from the box body 1 is fixedly connected to the scraping plate 17. A sliding rod 22 is fixedly installed below the reciprocating lead screw 19. One side surface of the sliding rod 22 is fixedly connected to the box body 1. The other side surface of the sliding rod 22 is fixedly connected to the scraping plate 17. A conveyor belt 23 is arranged inside the box body 1. A sliding groove 24 is opened on one side surface of the top surface of the box body 1. A sliding block 25 is slidably connected inside the sliding groove 24. The bottom surface of the sliding block 25 is fixedly connected to the filter net 13. As Figure 2 shown, through the cooperation between the high-temperature steam pipe 20 and the nozzles 21, the sludge can be quickly dried.

[0034] A threaded sleeve 26 is sleeved on the surface of the reciprocating lead screw 19. The threaded sleeve 26 is penetrated by the sliding rod 22. The middle of the bottom surface of the threaded sleeve 26 is fixedly connected to a connecting rod 27. A plurality of racks 28 are fixedly installed on the bottom surface of the connecting rod 27. Card slots 29 are opened on one sides of the sliding block 25 and the sliding block 11. The card slots 29 are engaged with the clamping rod 1207. As Figure 3 、6 As shown, by rotating the reciprocating lead screw 19, the movement of the threaded sleeve 26 can be driven. At the same time, through the through connection between the slide bar 22 and the threaded sleeve 26, the threaded sleeve 26 can be limited. At the same time, the rack 28 divides the sludge on the conveyor belt 23, so that the sludge can be dried better.

[0035] Working principle: Before using this sludge pretreatment device based on sludge power generation, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6 As shown, first, by setting the fixing component 12, by pushing the push rod 1203, the movement of the slide plate 1202 can be driven. Through the movement of the slide plate 1202, the roller 1205 on the slide plate 1202 descends as the slide plate 1202 moves. At the same time, the descent of the roller 1205 can drive the descent of the clamping rod 1207. Through the descent of the clamping rod 1207, the clamping rod 1207 is separated from the clamping groove 29, so that the filter plate 9 or the filter net 13 can be taken out. At the same time, when installing the filter plate 9 or the filter net 13, by loosening the push rod 1203, the push rod 1203 returns to its original position under the action of the first spring 1204. When the push rod 1203 returns to its original position, it will lift the roller 1205, so that the clamping rod 1207 can be driven to rise, so that the clamping rod 1207 is engaged with the clamping groove 29 again. Thus, when the staff replaces or installs the filter plate 9 or the filter net 13, it can be more convenient, thereby improving the work efficiency of the staff. At the same time, the clamping between the clamping groove 29 and the clamping rod 1207 is tight, so as to reduce the occurrence of the separation of the clamping groove 29 and the clamping rod 1207.

[0036] Secondly, by setting the drive motor 3, the belt 18, the scraper 17, the reciprocating lead screw 19, the slide bar 22, the threaded sleeve 26, the connecting rod 27 and the rack 28, by starting the drive motor 3, the rotation of the belt 18 can be driven. Through the rotation of the belt 18, the rotation of the reciprocating lead screw 19 can be driven. Through the rotation of the reciprocating lead screw 19, the movement of the threaded sleeve 26 can be driven. At the same time, through the through connection between the slide bar 22 and the threaded sleeve 26, a limiting effect can be exerted on the threaded sleeve 26, so as to ensure that the threaded sleeve 26 can move as the reciprocating lead screw 19 rotates. At the same time, through the connecting rod 27 and the rack 28, the dehydrated sludge on the conveyor belt 23 can be divided, so that the sludge can be dried more quickly, thereby improving the efficiency.

[0037] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art 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 utility model shall be included within the protection scope of the present utility model.
