Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment, in particular to a drying device for sludge treatment. Background Technique

[0002] Sludge treatment refers to the process of reducing the volume, weight, stabilizing, rendering harmless and recycling the sludge generated in the sewage treatment process. The main purpose of sludge treatment is to reduce the volume, stabilize, render harmless and promote the recycling of sludge. The moisture content of sludge is usually very high, generally above 90%. Even after pressure filtration, the moisture content is often about 80%. Using a drying device can effectively reduce the moisture content of sludge, thereby reducing the volume and weight of sludge, which is very important for subsequent transportation, storage and disposal, and can significantly reduce related costs. The sludge after drying treatment has a lower moisture content, and some organic substances have been transformed. These treated sludges can be used as fertilizers to provide organic fertilizers for agricultural production and realize the recycling of waste. Using a drying device in sludge treatment has multiple advantages such as reducing the volume and weight of sludge, improving the hygienic safety of sludge, promoting the recycling of sludge, reducing treatment costs and meeting environmental protection requirements.

[0003] When the existing sludge drying device dries sludge, the sludge is easily adhered to the inner wall of the drying device, affecting the heat transfer in the drying device and resulting in a reduction in the drying efficiency of the drying device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drying device for sludge treatment. By installing a cleaning mechanism on the rotating rod, the second long plate of the cleaning mechanism can clean and scrape the inner side wall of the drying box, ensuring that the inner side wall of the drying box will not have sludge adhesion and improving the sludge drying effect.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-4 , a drying device for sludge treatment, including a drying oven 1 and a stirring mechanism 4. A top plate 2 is installed on the drying oven 1. A discharge port 101 is opened at the bottom end of the drying oven 1. A feed port 3 is opened on the top plate 2. The drying oven 1 and the top plate 2 form an integral body. Through the feed port 3 on the top plate 2, sludge can be placed inside the drying oven 1. The sludge enters the inside of the drying oven 1, and the dried sludge is discharged through the discharge port 101. The stirring mechanism 4 includes a support 401 and a motor 402. The motor 402 uses a brushless DC motor with the model JC35W5. The motor 402 is installed on the top surface of the top plate 2 through the support 401. A rotating rod 403 is installed on the output shaft of the motor 402. One end of the rotating rod 403 extends into the inside of the drying oven 1 at the bottom end of the top plate 2. Stirring rods 404 are arranged on the rotating rod 403. By the motor 402, the stirring rods 404 inside the drying oven 1 can be rotated to stir the sludge inside the drying oven 1 to prevent the sludge from caking during the drying process.

[0022] A cleaning mechanism 5 is installed on the rotating rod 403. The cleaning mechanism 5 includes a second long plate 505. One side of the second long plate 505 is attached to the inner side wall of the drying oven 1. A base 6 is arranged at the bottom end of the rotating rod 403. The base 6 is installed on the inner bottom surface of the drying oven 1. While the rotating rod 403 rotates, the cleaning mechanism 5 rotates on the base 6 of the drying oven 1, so that the second long plate 505 can clean and scrape the inner side wall of the drying oven 1, ensuring that there is no sludge adhesion on the inner side wall of the drying oven 1 and improving the sludge drying effect.

[0023] Both sides of the rotating rod 403 are provided with a chute 405 and a through hole 406. The cleaning mechanism 5 is slidably fitted inside the chute 405. The cleaning mechanism 5 further includes two first long plates 501 and bolts 506. One end of each of the two first long plates 501 is provided with a slider 502, and the slider 502 is slidably fitted inside the chute 405. The bolt 506 is connected to the slider 502 through the through hole 406. The other ends of the two first long plates 501 are movably provided with a round rod 503. Both ends of the round rod 503 are provided with side plates 504, and the side plates 504 are connected to the second long plate 505. The second long plate 505 is slidably fitted on the rotating rod 403 through the slider 502 and the bolt 506 on one side of the two first long plates 501, which is convenient for disassembling the second long plate 505 after long-term use, making the use more convenient.

[0024] A fixed block 407 is provided at the bottom end of the chute 405. The fixed block 407 is fitted inside the base 6. The base 6 includes a ring 601. A bearing 602 is installed inside the ring 601. The inner ring of the bearing 602 is installed with a circular plate 603. A card slot 604 is provided on the circular plate 603. The fixed block 407 is fitted inside the card slot 604. The stirring mechanism 4 installed on the top plate 2 is limited inside the drying box 1 through the base 6, ensuring that the rotating rod 403 of the stirring mechanism 4 drives the cleaning mechanism 5 to rotate inside the drying box 1 without deviation, ensuring the use of the user.

[0025] When using the drying device to treat sludge, place the drying box 1 at the designated position required by the user. Through the feeding port 3 on the top plate 2 of the drying box 1, sludge can be placed inside the drying box 1, so that the sludge to be dried can enter the inside of the drying box 1. Start the motor 402 on the bracket 401 of the top plate 2. The output shaft of the motor 402 drives the rotating rod 403 to rotate. Thus, the stirring rod 404 on the rotating rod 403 can rotate inside the drying box 1 to stir the dried sludge inside the drying box 1, increasing the heat received by the sludge inside the drying box 1 during drying. At the same time, the second long plate 505 of the cleaning mechanism 5 installed on the rotating rod 403 through the chute 405 and the through hole 406 can rotate in contact with the inner side wall of the drying box 1 to clean the sludge attached to the inner side wall of the drying box 1, avoiding the sludge during drying from adhering and accumulating on the inner side wall of the drying box 1, improving the drying efficiency of the sludge inside the drying box 1, and avoiding the situation of uneven and incomplete drying of the sludge. After the drying device is used up, move the top plate 2 upward to separate the fixed block 407 of the stirring mechanism 4 from the card slot 604 of the circular plate 603 of the base 6. Rotate and disassemble the bolt 506 that is threadedly engaged with the slider 502 through the through hole 406. Slide the two first long plates 501 and the slider 502 through the round rod 503 and the chute 405, so that the cleaning mechanism 5 can be integrally disassembled from the rotating rod 403, which is convenient for the user to replace and clean the cleaning mechanism 5, ensuring the secondary use of the cleaning mechanism 5 and improving the service life of the drying device.
