Description

Technical Field

[0001] This utility model relates to a self-cleaning sludge drying mechanism, specifically a self-cleaning sludge drying mechanism, belonging to the field of sludge technology. Background Technology

[0002] Sludge is a byproduct of wastewater treatment. It is an extremely complex heterogeneous substance composed of organic debris, bacterial cells, inorganic particles, and colloids. The main characteristics of sludge are high water content (up to 99% or more), high organic matter content, easy putrefaction and odor, fine particles, low specific gravity, and a colloidal liquid state. It is a viscous substance between liquid and solid and can be transported by pumps. However, it is difficult to separate solids and liquids through sedimentation. Therefore, when treating sludge, we will dry it.

[0003] Chinese Patent Publication CN219409528U discloses a sludge drying mechanism for sewage treatment. By optimizing the setting of a dewatering device above the drying chamber, the sludge can be dewatered through a first electric push rod, a piston rod, a sewage collection pipe, a second electric push rod, and a screen. This facilitates rapid dewatering of the sludge, effectively reduces the internal water content of the sludge, and helps improve the working efficiency of the device in drying sludge.

[0004] After the aforementioned patented technology involves drying the sludge, some sludge inevitably adheres to the inner wall of the drying mechanism. However, existing cleaning methods rely on manual labor, which significantly increases cleaning time and makes cleaning difficult. Therefore, a self-cleaning sludge drying mechanism is proposed here. Utility Model Content

A hydraulic device is fixedly mounted on the upper surface of each support plate, and a connecting plate is fixedly mounted on the telescopic end of each hydraulic device. A connecting column is fixedly mounted on the bottom surface of each connecting plate, and the bottom end of each connecting column penetrates the drying cylinder and extends into its interior. A scraper is fixedly mounted on the bottom surface of both connecting columns, with its outer surface contacting the inner wall of the drying cylinder. A collection box is fixedly mounted on the bottom surface of the drying cylinder, and a baffle is slidably connected to the inner wall of the collection box, with its upper surface contacting the bottom surface of the collection box. Two sealing doors are hinged to the front of the collection box, and a door handle is fixedly mounted on the front of each sealing door. Two push-pull handles are fixedly mounted on the left side of the baffle.

[0007] Each of the support plates has a reinforcing member fixedly installed on its bottom surface, and the two reinforcing members are fixedly connected to the outer surface of the drying cylinder on their sides that are close to each other.

[0008] Two reinforcing blocks are fixedly installed on the outer surface of each hydraulic device, and the side of each set of reinforcing blocks that is close to each other is fixedly connected to the outer surface of the drying cylinder.

[0009] Two sets of bases are provided below the collection box, and the upper surface of each set of bases is fixedly connected to the bottom surface of the collection box.

[0010] Each of the door handles has a stabilizing block fixedly installed on its outer surface, and the back of each stabilizing block is fixedly connected to the front of the sealed door.

A scraper at the bottom of the connecting column adheres closely to the inner wall of the drying cylinder. Through the extension and retraction of the hydraulic device, the scraper flexibly removes the sludge adhering to the inner wall, eliminating the need for manual operation, significantly reducing cleaning time, and ensuring more thorough cleaning. A collection box collects the scraped sludge, and its inner wall baffle is slidable, facilitating sludge discharge and preventing accumulation.

[0016] Please see Figs. 1-4 This utility model provides a self-cleaning sludge drying mechanism, including a drying cylinder 1, a conveying pipe 5 fixedly connected to the upper surface of the drying cylinder 1, a plurality of heating devices 8 fixedly installed on the inner top wall of the drying cylinder 1, and a cleaning mechanism 6 provided on the outer side of the drying cylinder 1. The cleaning mechanism 6 includes two support plates 601. The sides of the two support plates 601 that are close to each other are fixedly connected to the outer surface of the drying cylinder 1. Each support plate 601 has a reinforcing member 9 fixedly installed on its bottom surface. The sides of the two reinforcing members 9 that are close to each other are fixedly connected to the outer surface of the drying cylinder 1. The fixed connection between the reinforcing members 9 on the bottom surface of the support plate 601 and the outer surface of the drying cylinder 1 enhances the connection stability between the support plate 601 and the drying cylinder 1, effectively preventing the support plate 601 from shifting or shaking when the cleaning mechanism 6 is working, ensuring that the entire cleaning mechanism 6 can operate stably, and improving the reliability and safety of the self-cleaning process.

[0017] A hydraulic device 602 is fixedly installed on the upper surface of each support plate 601. A connecting plate 603 is fixedly installed on the telescopic end of each hydraulic device 602. A connecting column 604 is fixedly installed on the bottom surface of each connecting plate 603. Two reinforcing blocks 4 are fixedly installed on the outer surface of each hydraulic device 602. The side of the two sets of reinforcing blocks 4 that are close to each other is fixedly connected to the outer surface of the drying cylinder 1. The reinforcing blocks 4 can play a good role in fixing the hydraulic device 602, preventing the hydraulic device 602 from loosening or shifting during the telescopic process, ensuring its normal operation, and enabling the scraper 610 to scrape the sludge on the inner wall of the drying cylinder 1 more accurately.

[0018] The bottom end of each connecting column 604 penetrates through the drying cylinder 1 and extends into the interior of the drying cylinder 1. A scraper 610 is fixedly installed on the bottom surface of the two connecting columns 604. The outer surface of the scraper 610 contacts the inner wall of the drying cylinder 1. A collection box 609 is fixedly installed on the bottom surface of the drying cylinder 1. Two sets of bases 2 are provided below the collection box 609. The upper surface of each set of bases 2 is fixedly connected to the bottom surface of the collection box 609. The bases 2 provide stable support for the collection box 609, so that it will not shake during operation, which facilitates the collection of scraped sludge and also makes it convenient to move and place the collection box 609.

[0019] A baffle 605 is slidably connected to the inner wall of the collection box 609. The upper surface of the baffle 605 contacts the bottom surface of the collection box 609. Two sealing doors 607 are hinged to the front of the collection box 609. A door handle 606 is fixedly installed on the front of each sealing door 607. A stabilizing block 7 is fixedly installed on the outer surface of each door handle 606. The back of each stabilizing block 7 is fixedly connected to the front of the sealing door 607. The stabilizing block 7 enhances the structural strength of the door handle 606, making it more secure and reliable when opening the sealing door 607 using the door handle 606, and extending the service life of the door handle 606.

[0020] Two push-pull handles 608 are fixedly installed on the left side of the baffle 605. The two push-pull handles 608 are fixedly installed on the same side that are close to each other. The right side of the fixing block 3 is fixedly connected to the left side of the baffle 605. The fixing block 3 makes the connection between the push-pull handles 608 and the baffle 605 more stable, makes it easier to operate the baffle 605, facilitates the control of the sliding of the baffle 605, and improves cleaning efficiency.

[0021] When using this utility model: First, the sludge is fed into the drying cylinder 1 through the conveying pipe 5. After the sludge enters, the heating device 8 on the inner top wall starts to work and emits heat to dry the sludge. During the drying process, the moisture in the sludge gradually evaporates, but some of the dried sludge may stick to the inner wall of the drying cylinder 1. After drying is complete, the cleaning mechanism 6 needs to be activated for cleaning. The operator opens the sealed door 607 on the front of the collection box 609 through the door handle 606, and then holds the push-pull handle 608 to pull the baffle 605. The baffle 605 slides on the inner wall of the collection box 609, temporarily preventing the sludge inside the collection box 609 from falling. Then, the hydraulic device 602 is activated. The telescopic end of the hydraulic device 602 begins to move, driving the connecting plate 603 and the connecting column 604 to move together. The scraper 610 at the bottom of the connecting column 604 also moves inside the drying cylinder 1. The scraper 610 is close to the inner wall of the drying cylinder 1, scraping off the sludge adhering to the inner wall. The scraped sludge falls into the collection box 609. After the scraper 610 has scraped one circle, the hydraulic device 602 stops working. Pull the baffle 605 again to open the baffle 605 to block the sludge, and the sludge in the collection box 609 can be discharged smoothly. After the sludge is discharged, push the baffle 605 back to its original position and close the sealing door 607. The whole cleaning process is completed. In this way, the inner wall of the drying cylinder 1 becomes clean and the next round of sludge drying work can continue, which greatly improves work efficiency and avoids the trouble of manual cleaning.
