[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 , Figure 4 The utility model provides an embodiment: an environmentally friendly sludge dehydration and solidification treatment device, including a conveyor 1, which can convey sludge. A box 5 is arranged on the top of the conveyor 1, and the box 5 can dehydrate the sludge and mix the dehydrated sludge with a solidifying agent and then drop it out from a mud outlet 4. A mud outlet 4 is opened at the bottom of the box 5, and a cleaning component is arranged at the bottom of the conveyor 1. The cleaning component includes a scraper 25, and the scraper 25 contacts the conveyor belt at the bottom of the conveyor 1, so that the sludge adhered to the conveyor belt can be scraped off and dropped into the collecting box 2 for collection, which is convenient for collection and cleaning, thereby improving the convenience of cleaning, and at the same time preventing the accumulation and accumulation of sludge on the conveyor belt of the conveyor 1, thereby improving the transmission efficiency of the conveyor 1, so that subsequent cleaning can be convenient.

[0032] Furthermore, the front surface of the scraper 25 is fixedly connected to a slide bar 22, which serves to guide and limit the scraper 25. The bottom end of the conveyor 1 is fixedly connected to a fixed block 21, and the bottom end of the conveyor 1 is fixedly connected to a fixed block 211 near the rear of the fixed block 21. The fixed block 21 cooperates with the fixed block 211 to support the scraper 25. The rear surface of the fixed block 211 is fixedly connected to a positioning plate 212, which serves to position the collection box 2. The sludge scraped off by the scraper 25 is collected below the plate 25. The scraper 25 is slidably connected between the fixed block 1 21 and the fixed block 211. A positioning groove 24 is provided at the bottom end of the conveyor 1. A positioning block 23 is inserted into the inner wall of the positioning groove 24. The positioning groove 24 plays a role in supporting the positioning block 23. The bottom end of the positioning block 23 is fixedly connected with a collecting box 2. The collecting box 2 slides on the outer walls of the fixed block 1 21 and the fixed block 211. The collecting box 2 can collect the sludge scraped off by the scraper 25.

[0033] Reference Figure 1 - Figure 2 A guide assembly is provided at the top of the conveyor 1, and the guide assembly includes a baffle 3. The baffle 3 is fixedly connected to the top of the conveyor 1 and is provided in two groups. The two groups of baffles 3 are symmetrically arranged with the center line of the conveyor 1 as the symmetry axis. The two groups of baffles 3 can play a protective role to prevent the fallen sludge from falling to the outside of the conveyor 1.

[0034] Reference Figure 1 , Figure 3 , Figure 4 The slide rod 22 passes through and is slidably connected to the front surface of the fixed block 21. A slide groove 29 is provided on the right side of the outer wall of the slide rod 22. The slide groove 29 can prevent the limit block 210 from rotating. The inner wall of the slide groove 29 is slidably connected to the limit block 210. The limit block 210 slides into the limit groove 26 to limit the scraper 25. One end of the spring 28 is fixedly connected to the front surface of the limit block 210.

[0035] Reference Figure 1 , Figure 3 , Figure 4 The other end of the spring 28 is fixedly connected to the front rear surface of the sliding rod 22, and the limit block 210 can be driven to move and squeeze the spring 28 by moving the shift block 27. At this time, the limit block 210 can be moved out of the limit groove 26 to release the limit of the scraper 25, and the scraper 25 can be moved to release the contact with the bottom end of the conveyor 1, thereby preventing continuous friction from damaging the conveyor 1, thereby improving the service life of the conveyor 1. At the same time, the reverse force of the spring 28 being squeezed can drive the limit block 210 to reset and slide into the limit groove 26 to limit the sliding rod 22 and the scraper 25. The top of the limit block 210 is fixedly connected with a shift block 27 that drives the limit block 210 to move. The front surface of the fixed block 21 is provided with a limit groove 26 and multiple groups are provided. The limit block 210 slides on the inner wall of the limit groove 26, and the limit block 210 slides into the limit groove 26 to limit the scraper 25.

[0036] Reference Figure 1 - Figure 2 A guide block 31 is fixedly connected between the two groups of baffles 3. The guide block 31 is arranged below the mud outlet 4. The right side of the guide block 31 is arranged as an inclined surface. After the sludge passes through the bottom end of the mud outlet 4 and falls onto the guide block 31, the right side of the guide block 31 is arranged as an inclined surface, so that the sludge can slide along the inclined surface to the conveyor 1, thereby preventing the sludge falling from the mud outlet 4 from directly falling on the conveyor 1 and causing an impact on the conveyor 1, thereby reducing the impact on the conveyor 1 and increasing the service life of the conveyor 1.

[0037] Working principle: When in use, the agitated and mixed sludge falls from the sludge outlet 4, and the falling sludge is blocked by the baffle 3 to prevent it from falling outside the conveyor 1. At the same time, after falling onto the guide block 31, it slides onto the conveyor 1, thereby preventing the sludge from directly falling onto the conveyor 1 and impacting the conveyor 1, thereby increasing the service life of the conveyor 1.

[0038] After the positioning block 23 is driven by the moving collecting box 2 to slide into the positioning groove 24, it is moved to the right side to contact the positioning plate 212, and the collecting box 2 is limited by the positioning plate 212. At this time, when the conveyor 1 is started, the conveyor belt is conveyed, and the scraper 25 contacts the conveyor belt during the conveying, so that the sludge adhering to the conveyor belt is scraped off. After the sludge is scraped off, it falls into the collecting box 2 for collection. When the scraping is completed, the limiting block 210 is driven by the moving dial block 27 to slide out of the limiting groove 26 and squeeze the spring 28 at the same time, The contact slide bar 22 and the scraper 25 are limited. At this time, after the scraper 25 and the slide bar 22 are moved downward, the reverse force of the spring 28 is squeezed to drive the limit block 210 to reset, so that the limit block 210 slides into the limit groove 26 to limit the limit block 210 and the slide bar 22, thereby limiting the scraper 25. At this time, by removing the scraper 25 to release the contact with the conveyor belt, continuous friction can be prevented from reducing the service life of the conveyor belt. At this time, the collection box 2 can be moved and the collection box 2 can be easily cleaned after being moved out, thereby improving the cleaning effect.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
