Technical Field
[0001] This utility model relates to the technical field of carbon-free sludge hot water hydrolyzers, specifically a carbon-free sludge hot water hydrolyzer. Background Technology

It primarily uses hot water hydrolysis technology to improve the biodegradability of sludge, promoting subsequent anaerobic digestion or aerobic treatment. This process utilizes high-temperature, high-pressure hot water hydrolysis and flash evaporation to break down the cell walls of biological sludge and decompose organic matter. However, existing devices still have some shortcomings; for example:
[0003] For example, a carbon-free sludge hydrolyzer with announcement number CN217868568U, when in use, includes a conical seat and a stirring mechanism; the conical seat has a cylindrical body at its upper end, with a sealing plate at the upper opening of the cylindrical body, and a guide tube inside the cylindrical body via a support, with a baffle plate in the middle of the inner arc surface of the guide tube, and evenly distributed round holes at both the upper and lower ends of the outer arc surface of the guide tube; the stirring mechanism is located inside the cylindrical body, and its lower end cooperates with the guide tube; it also includes an inlet pipe and an outlet pipe. The feed pipe is located in a through hole on the outer side of the upper surface of the sealing plate, and the discharge pipe is located in a discharge hole in the middle of the lower end face of the conical seat. The above-mentioned device has some problems. Although the device can be used to complete the thermal hydrolysis of sludge, it usually discharges directly through the discharge pipe. Because it is not easy to prevent blockage during the discharge process, the effect of the sludge thermal hydrolyzer is difficult to achieve the expected results. Therefore, we propose a carbon-free sludge thermal hydrolyzer device to solve the above-mentioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This utility model provides a technical solution: a carbon-free sludge hot hydrolyzer, comprising a base 1 and a body 2. The base 1 is fixedly connected to a first motor 3, which is connected to a first rotating shaft 4. The first rotating shaft 4 is connected to a first gear 5, which meshes with a gear ring 6. The gear ring 6 is fixedly connected to the body 2. The lower part of the body 2 is fixedly connected to a support rod 7, which is slidably connected to the interior of the base 1. The interior of the body 2 is connected to a rotating rod 11 via a rotating mechanism. The rotating mechanism includes a second motor 8, a second gear 9, a third gear 10, a rotating rod 11, and a stirring rod 12. The body 2 is fixedly connected to the second motor 8, and the second motor 8 is connected to the second gear 9. The second gear 9 meshes with the third gear 10, and the third gear 10 is connected to the rotating rod 11. The stirring rod 12 is arranged in an array about the surface of the rotating rod 11. The scraper 13 on the surface of the rotating rod 11 contacts the side wall of the body 2. The push plate 14 connected to the surface of the rotating rod 11 contacts the lower inner wall of the body 2. The surface of the rotating rod 11 and the stirring rod 12 are fixedly connected. The surface of the rotating rod 11, the scraper 13, and the push plate 14 are fixedly connected. A heating plate 15 is provided inside the body 2, and the heating plate 15 contacts the heat-conducting plate 16.
[0019] During operation, sludge is added into the machine body 2 through the upper feed pipe. Before adding the sludge, the heating plate 15 and heat-conducting plate 16 inside the machine body 2 are activated to preheat the internal temperature of the machine body 2. At this time, the sludge is heated upon entry. Simultaneously, the second motor 8 inside the machine body 2 is activated, driving the second gear 9 to rotate. Since the second gear 9 meshes with the third gear 10, the third gear 10 drives the rotating rod 11 to rotate, causing the rotating rod 11 to drive the multiple stirring rods 12 on the surface to rotate. The stirring rods 12 stir the sludge inside, thus... The heating effect is better. At the same time, the rotating rod 11 drives the scraper 13 to rotate, so that the scraper 13 continuously scrapes the sludge from the inner wall of the machine body 2 for stirring and heating. During the stirring and heating process, the first motor 3 drives the first rotating shaft 4 to rotate. At this time, the first rotating shaft 4 drives the first gear 5 to rotate. Since the first gear 5 and the gear ring 6 mesh, the gear ring 6 drives the machine body 2 to rotate. Meanwhile, the support rod 7 under the machine body 2 slides inside the base 1. The stirring rod 12, together with the stirring rod 12 inside the machine body 2, can make the stirring effect of the sludge better and heat the sludge more evenly.
[0020] The machine body 2 is equipped with a feeding mechanism, which includes a third motor 17, a turntable 18, and a feeding hole 19. The machine body 2 is fixedly connected to the third motor 17, and the third motor 17 is connected to the turntable 18. The surface of the turntable 18 is provided with a feeding hole 19, which is the same size as the feeding pipe inside the machine body 2. The machine body 2 is also equipped with a discharge pipe 20, which contains a discharge mechanism. The discharge mechanism includes the discharge pipe 20, a push rod 21, a moving plate 22, and a fourth... The machine body 2 has a motor 23, a second rotating shaft 24, a rotating plate 25, a discharge pipe 20 and a push rod 21, the front end of the push rod 21 and the moving plate 22 are fixedly connected, the discharge pipe 20 and the fourth motor 23 are fixedly connected, the fourth motor 23 and the second rotating shaft 24 are connected, the surface of the second rotating shaft 24 and the rotating plate 25 are fixedly connected, and the rotating plate 25 is arranged in an array about the surface of the second rotating shaft 24. A water tank 26 is provided on the top of the machine body 2, and the water tank 26 and the high-pressure nozzle 27 are connected.
[0021] After heating is complete, the third motor 17 is started to drive the turntable 18 to rotate, so that the discharge hole 19 on the surface of the turntable 18 coincides with the discharge pipe inside the machine body 2. The sludge enters the discharge pipe and then the discharge pipe 20. At the same time, the rotating rod 11 drives the push plate 14 on the surface to rotate, and the push plate 14 pushes the sludge into the discharge pipe and into the discharge pipe 20 for discharge. If a blockage occurs during the discharge process, the discharge pipe 20 is closed, and the push rod 21 is started to drive the moving plate 22 to move. The moving plate 22 pushes the sludge to one side. At the same time, the fourth motor 23 is started to drive the second rotating shaft 24 to rotate, so that the second rotating shaft 24 drives the multiple rotating plates 25 on the surface to rotate, which can promote the discharge of sludge and prevent blockage during the discharge process. After use, the multiple high-pressure nozzles 27 inside the machine body 2 can be started to spray water from the water tank 26 onto the inner wall of the machine body 2, which, together with the rotating scraper 13 and the push plate 14, can be used for cleaning. Cleaning should be carried out in time after use to prevent sludge deposition and carbon buildup.
[0022] Working Principle: When using the carbon-free sludge hydrolyzer, sludge is added into the machine body 2 through the upper feed pipe. Before adding the sludge, the heating plate 15 and heat conduction plate 16 inside the machine body 2 are activated to preheat the internal temperature of the machine body 2. At this time, the sludge is heated after entering. Simultaneously, the second motor 8 inside the machine body 2 is activated, driving the second gear 9 to rotate. Since the second gear 9 meshes with the third gear 10, the third gear 10 drives the rotating rod 11 to rotate, causing the rotating rod 11 to drive the multiple stirring rods 12 on the surface to rotate. The stirring rod 12 agitates the internal sludge, improving the heating effect. Simultaneously, the rotating rod 11 drives the scraper 13 to rotate, continuously scraping down the sludge from the inner wall of the machine body 2 for agitation and heating. During this agitation and heating process, the first motor 3 drives the first rotating shaft 4 to rotate. The first rotating shaft 4 then drives the first gear 5 to rotate. Since the first gear 5 meshes with the gear ring 6, the gear ring 6 drives the machine body 2 to rotate. Meanwhile, the support rod 7 below the machine body 2 slides inside the base 1. The combined effect of the stirring rod 12 and the internal stirring rod 12 of the machine body 2 enhances the agitation of the sludge. To better and more evenly heat the sludge, after heating is complete, the third motor 17 is started to drive the turntable 18 to rotate, so that the discharge hole 19 on the surface of the turntable 18 coincides with the discharge pipe inside the machine body 2. The sludge enters the discharge pipe and then the discharge pipe 20. At the same time, the rotating rod 11 drives the push plate 14 on the surface to rotate, and the push plate 14 pushes the sludge into the discharge pipe and into the discharge pipe 20 for discharge. If a blockage occurs during the discharge process, the discharge pipe 20 is closed, and the push rod 21 is started to drive the moving plate 22 to move. The moving plate 22 pushes the sludge to one side. When the fourth motor 23 is started, it drives the second rotating shaft 24 to rotate, which in turn drives multiple rotating plates 25 on the surface to rotate. This promotes the discharge of sludge and prevents blockage during the discharge process. After use, multiple high-pressure nozzles 27 inside the machine body 2 can be activated to spray water from the water tank 26 onto the inner wall of the machine body 2. This, together with the rotating scraper 13 and pusher 14, cleans the machine. Timely cleaning after use prevents sludge deposition and carbon buildup, thus completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
