Description

Technical Field

[0001] The invention relates to the technical field of organic sludge treatment, and in particular to a novel integrated equipment for intelligent and environmentally friendly treatment of organic sludge into carbon organic matter. Background Art

[0002] Organic sludge refers to sludge with organic matter as the main component. It is the product of treating organic wastewater (including domestic sewage). Its main characteristics are high organic content, easy to decompose and stink, fine particles, small specific gravity, high water content and not easy to dehydrate, and it is a hydrophilic substance with a colloidal structure and easy to transport through pipes. In addition, organic sludge often contains a lot of plant nutrients, parasite eggs, pathogenic microorganisms and heavy metal ions. Both primary sedimentation sludge and secondary sedimentation sludge are organic sludge;

[0003] It is necessary to use treatment equipment to convert organic sludge into carbonaceous products (such as biochar). Through pyrolysis in a high-temperature anaerobic or low-oxygen environment, the organic matter in the sludge is converted into carbonaceous products. This process is called sludge carbonization. The carbonized product, biochar, has a high calorific value and can be used for energy recovery. It is also rich in minerals and trace elements and can be used in soil improvement, fertilizer production and other fields, realizing the resource utilization of sludge.

[0004] Since the moisture content of the original sludge is usually above 80%, the high moisture content not only increases the volume and weight of the sludge, but also makes it difficult to transport, store and handle. Through dehydration treatment, the water in the sludge can be removed to reduce its moisture content, thereby reducing the volume and weight of the sludge and facilitating subsequent carbonization treatment. In response to the above problems, the inventors proposed a new type of organic sludge to carbon organic intelligent environmental protection disposal integrated equipment to solve the above problems.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example: Figure 1-7 As shown, the present invention provides a novel integrated equipment for intelligent and environmentally friendly disposal of organic sludge into carbon organic matter, including a treatment barrel 1, to which a partition 2 is fixedly connected, and the partition 2 divides the interior of the treatment barrel 1 into two sections: a stirring chamber 3 and a centrifugal chamber 4. The interior of the stirring chamber 3 is rotatably connected with an agitator 5, and the interior of the centrifugal chamber 4 is provided with a centrifugal barrel 6. The agitator 5 and the centrifugal barrel 6 are transmitted by setting a linkage component 7. A feed pipe 25 that communicates with the interior of the partition 2 is fixedly connected to the middle of the bottom end of the partition 2, and the bottom end of the feed pipe 25 extends into the centrifugal barrel 6.

[0025] The linkage assembly 7 includes a rotating rod 71, which is rotatably installed on one side of the processing cylinder 1. The top of the rotating rod 71 is fixedly connected to a synchronous wheel 72, and the bottom of the rotating rod 71 is fixedly connected to a synchronous wheel 2 73. The top of the rotating shaft of the agitator 5 extends to the top of the processing cylinder 1 and is fixedly connected to a synchronous wheel 3 74. The outer sides of the synchronous wheel 1 72 and the synchronous wheel 3 74 are connected by a belt drive. The bottom end of the centrifugal cylinder 6 is fixedly connected to a rotating tube 75 that communicates with the inside of the centrifugal cylinder 6. The bottom end of the rotating tube 75 extends to the bottom end of the processing cylinder 1 and is fixedly connected to a synchronous wheel 4 76. The synchronous wheel 4 76 and the outer sides of the synchronous wheel 2 73 are connected by a belt drive.

[0026] By adopting the above technical solution, when the agitator 5 rotates, the synchronous wheel three 74 is driven to rotate, and the synchronous wheel one 72 is connected to the outer side of the synchronous wheel three 74 through a belt transmission, and the rotating rod one 71, the synchronous wheel one 72 and the synchronous wheel two 73 are driven to rotate at the same time, and the synchronous wheel two 73 is connected to the outer side of the synchronous wheel four 76 through a belt transmission, and the rotating tube 75 and the centrifugal cylinder 6 are driven to rotate at the same time, thereby realizing the linkage between the agitator 5 and the centrifugal cylinder 6.

[0027] A mounting seat 8 is fixedly connected to one side of the top of the processing cylinder 1, and an electric cylinder 9 is rotatably installed on the inner side of the mounting seat 8. A rotating shaft rod 10 is rotatably connected to the top of the partition 2. The bottom end of the rotating shaft rod 10 extends to the interior of the centrifugal cylinder 6 and is fixedly connected to a scraper 11. The top of the rotating shaft rod 10 extends to the top of the processing cylinder 1 and is fixedly connected to a rotating plate 12. The piston rod of the electric cylinder 9 is rotatably connected to the rotating plate 12.

[0028] By adopting the above technical solution, when the centrifugal drum 6 centrifugally filters the moisture in the sludge, the sludge will adhere to the inner side of the drum wall of the centrifugal drum 6. During cleaning, one end of the piston rod of the mounting seat 8 is pushed by the extension to rotate around the central axis of the rotating shaft rod 10, and at the same time, the scraper 11 is driven to rotate, so that the scraper 11 is in conflict with the inner wall of the centrifugal drum 6, and then the centrifugal drum 6 is rotated to cause a relative displacement between the scraper 11 and the centrifugal drum 6, so that the sludge attached to the inner wall of the centrifugal drum 6 is scraped off.

[0029] An L-shaped tube 13 is fixedly connected to one side of the bottom of the treatment tube 1 close to the rotating tube 75, and the L-shaped tube 13 is communicated with the interior of the rotating tube 75. A mounting plate 14 is fixedly connected to one side of the bottom of the treatment tube 1, and a fan 15 is fixedly installed on the top of the mounting plate 14. A bellows 16 is fixedly connected to the input end of the fan 15, and the bottom end of the bellows 16 is fixedly connected to the L-shaped tube 13.

[0030] By adopting the above technical solution, the sludge inside the centrifugal drum 6 is drawn out through the channel formed by the rotating tube 75, the L-shaped tube 13 and the corrugated tube 16 by the fan 15, thereby achieving the discharge of the sludge.

[0031] The bottom end of the processing cylinder 1 is fixedly connected with an annular slide rail 19 , and the bottom end of the centrifugal cylinder 6 is fixedly connected with an annular slider 18 , which is slidably engaged with the top outer side of the annular slide rail 19 .

[0032] By adopting the above technical solution, through the cooperation between the annular slider 18 and the annular slide rail 19, the annular slide rail 19 is used to support and guide the annular slider 18, ensuring that the centrifugal cylinder 6 always maintains a stable motion trajectory during the rotation process, avoiding the reduction of separation effect or damage to the equipment due to shaking or vibration.

[0033] The rotating tube 75 and the L-shaped tube 13 are connected via a rotating joint 17 .

[0034] By adopting the above technical solution and providing the rotary joint 17, it is ensured that the rotating tube 75 and the L-shaped tube 13 can transport the sludge while being able to rotate relative to each other.

[0035] An L-shaped plate 20 is fixedly connected to the top of the processing cylinder 1 near the synchronous wheel 3 74 , and a variable speed motor 21 is fixedly installed on the top of the L-shaped plate 20 . The driving end of the variable speed motor 21 is fixedly connected to the rotating shaft of the agitator 5 .

[0036] By adopting the above technical solution and providing a variable speed motor 21, it is convenient to drive the device.

[0037] The top of the treatment cylinder 1 is fixedly connected to a sewage inlet pipe 22 which is communicated with the interior of the treatment cylinder 1 , the top of the treatment cylinder 1 close to the sewage inlet pipe 22 is fixedly connected to a filling pipe 23 which is communicated with the interior of the treatment cylinder 1 , and the bottom of the treatment cylinder 1 is fixedly connected to a drainage pipe 24 which is communicated with the interior of the treatment cylinder 1 .

[0038] By adopting the above technical solution, by setting the sewage inlet pipe 22, it is convenient to inject the sludge to be treated into the interior of the treatment barrel 1, and by setting the filling pipe 23, it is convenient to add flocculant into the interior of the treatment barrel 1, and the water separated during the centrifugal drying process is discharged through the drain pipe 24.

[0039] The feed pipe 25 and the rotating pipe 75 are both provided with a solenoid valve 26 .

[0040] By adopting the above technical solution and providing the solenoid valve 26 , it is convenient to control the opening and closing of the feed pipe 25 and the rotating pipe 75 .

[0041] The diameter of the synchronous wheel 2 73 is greater than the diameter of the synchronous wheel 4 76 .

[0042] By adopting the above technical solution, by setting the diameter of the synchronous wheel 2 73 to be larger than the diameter of the synchronous wheel 4 76, it is convenient to control the transmission ratio of the agitator 5 and the centrifugal drum 6, thereby achieving stable and efficient operation of the equipment.

[0043] Working principle: When dehydrating the organic sludge, the water-containing sludge is injected into the interior of the stirring chamber 3 through the sewage inlet pipe 22, and then the flocculant is added into the interior of the stirring chamber 3 through the filling pipe 23. After the flocculant is added, the flocculant can be adsorbed on the surface of the sludge particles, so that the sludge particles are aggregated to form large flocs, which is convenient for subsequent centrifugal dehydration. At the same time, the agitator 5 is driven to rotate by the variable speed motor 21 to stir the materials in the stirring chamber 3, so that the flocculant is quickly and evenly dispersed into the sludge, ensuring that each sludge particle has the opportunity to contact with the flocculant. The sludge after flocculation treatment flows into the interior of the centrifuge cylinder 6 from the top of the feed pipe 25 by opening the solenoid valve 26;

[0044] When the agitator 5 rotates, it drives the synchronous wheel 3 74 to rotate. The synchronous wheel 1 72 is connected to the outer side of the synchronous wheel 3 74 through a belt transmission, and the rotating rod 1 71, the synchronous wheel 1 72 and the synchronous wheel 2 73 are driven to rotate. The synchronous wheel 2 73 is connected to the outer side of the synchronous wheel 4 76 through a belt transmission, and the rotating tube 75 and the centrifugal cylinder 6 are driven to rotate. The centrifugal cylinder 6 is used to centrifugally dehydrate the sludge falling into the centrifugal cylinder 6. During the centrifugal dehydration process, untreated sludge can be injected into the stirring chamber 3 and flocculated to further improve the dehydration efficiency.

[0045] The water that is finally separated is discharged from one end of the drain pipe 24, and the dried sludge will adhere to the inner side of the cylinder wall of the centrifugal cylinder 6. During cleaning, one end of the piston rod of the mounting seat 8 is pushed by the extension to rotate around the central axis of the rotating shaft rod 10, and at the same time, the scraper 11 is driven to rotate, so that the scraper 11 is in conflict with the inner wall of the centrifugal cylinder 6, and then the centrifugal cylinder 6 is rotated to cause a relative displacement between the scraper 11 and the centrifugal cylinder 6, so that the sludge attached to the inner wall of the centrifugal cylinder 6 is scraped off, and then the sludge inside the centrifugal cylinder 6 is extracted from the channel formed by the rotating tube 75, the L-shaped tube 13 and the bellows 16 by the fan 15 to realize the discharge of the sludge.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
