Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic slides, in particular to a sludge silo hydraulic slide. Background Art

[0002] The sludge solidification process generally involves transporting the sludge to a sludge silo through a transport side, then mixing it with a solidifying agent through conveyor belts and other conveying equipment for solidification, and finally transporting it away by a transport vehicle for landfill treatment. However, for solid or semi-fluid muddy sludge with high water content, it is difficult to release the sludge that has been accumulated for a long time and squeezed into a denser state due to its own gravity from the bottom of the silo or other container, that is, to complete the sludge unloading process. Since the sludge cannot be discharged smoothly from the outlet at the bottom of the silo by its own gravity, a unloading slide is set in the sludge silo to scrape out the sludge in the sludge silo. The existing sludge silo hydraulic slide (Announcement No.: CN207876463U) has the following disadvantages during use:

[0003] During use, the hydraulic cylinder pushes the connecting shaft toward the bottom of the silo, and the connecting shaft drives the slide to slide. The side scrapers on the slide scrape up the sludge at the bottom of the silo. Through the back-and-forth movement of the slide, the sludge scraped up by the side scrapers is brought into the scraper unit. The sludge in the scraper unit is evenly pushed into the spiral unloader during the back-and-forth movement of the slide. However, during the scraping process of the scraper unit, larger pieces of sludge can easily cause the discharge port to be blocked, thereby affecting the discharge of materials. For this reason, this patent proposes a hydraulic slide for sludge silos to solve the above problem. Utility Model Content

[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] Sludge solidification has become a widely used and widely recognized method for industrial sludge treatment in recent years. The primary mechanism involves adding a solidifying agent to the sludge to solidify it, ensuring that it meets the geomechanical properties required for sanitary landfill operations, thereby ensuring safe and sanitary landfill. The sludge solidification process typically involves transporting the sludge to a silo via a conveyor, mixing it with a solidifying agent, and solidifying it via conveyors and other transport equipment. Finally, it is transported by a transport vehicle to a landfill. However, for solid or semi-fluid sludge with a high water content, discharging the accumulated sludge, which has been compacted by gravity over a long period of time, from the bottom of a silo or other container—that is, completing the sludge unloading process—is difficult. Since the sludge cannot be discharged smoothly from the outlet at the bottom of the silo by its own gravity, a slide 1 is set in the sludge silo to scrape out the sludge in the sludge silo. The slide 1 is driven by the hydraulic rod 2 to move and push the sludge out. However, some large sludge pieces can easily cause the discharge port to be blocked, thereby affecting the discharge. The utility model provides a sludge silo hydraulic slide by setting multiple rotating rods 5. The outer wall of the rotating rod 5 is equipped with multiple crushing knives 6. By starting the motor 10, the motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 rotates to drive multiple worm sleeves 12 to rotate. The rotation of the worm sleeve 12 drives the worm gear 13 to rotate. The rotation of the worm gear 13 drives the rotating rod 5 to rotate. The rotating rod 5 rotates to drive multiple crushing knives 6 to rotate. The crushing knives 6 crush the sludge into small pieces. The small pieces of sludge can be better discharged from the discharge port, avoiding the blockage of the discharge port and affecting the discharge.

[0020] like Figures 1-4 As shown, the utility model provides a technical solution: a sludge silo hydraulic slide, including a slide 1, a plurality of rotating rods 5 are rotatably connected between the inner walls on both sides of the slide 1, and a plurality of crushing knives 6 are fixed to the outer wall of the rotating rod 5. The crushing knives 6 and the rotating rod 5 are fixed by bolts. When the crushing knives 6 are damaged later, the bolts can be removed and the crushing knives 6 can be replaced. A first mounting groove 8 and a second mounting groove 9 are opened on one side of the slide 1, and a rotating rod 11 is rotatably connected in the second mounting groove 9. A plurality of worm sleeves 12 corresponding to the rotating rod 5 are fixed on the outer wall of the rotating rod 11. After the rotating rod 5 passes through one side of the slide 1, a worm gear 13 is fixed on its outer wall. The worm gear 13 is meshed with the worm sleeve 12. A motor 10 is fixed in the first mounting groove 8, and the output end of the motor 10 is fixed to the rotating rod 11 after passing through the first mounting groove 8.

[0021] It should be noted that by starting the motor 10, the motor 10 drives the rotating rod 11 to rotate, the rotation of the rotating rod 11 drives the multiple worm sleeves 12 to rotate, the rotation of the worm sleeves 12 drives the worm wheel 13 to rotate, the rotation of the worm wheel 13 drives the rotating rod 5 to rotate, the rotation of the rotating rod 5 drives the multiple crushing knives 6 to rotate, the crushing knives 6 crush the sludge into small pieces, making it convenient for the slide 1 to push the sludge and avoid blockage of the discharge port affecting the discharge.

[0022] like Figure 1 and Figure 2 As shown, a hydraulic rod 2 is secured to one end of the carriage 1, and multiple connecting rods 3 are secured between the inner walls of both ends of the carriage 1. Multiple cleaning elements 4 are secured between the inner walls of both sides of the carriage 1, contacting the bottom inner wall of the sludge silo. The cleaning elements 4 and rotating rods 5 extend through the connecting rods 3, perpendicular to them. A connecting plate 7 is mounted on one side of the carriage 1 and secured to the carriage 1 via bolts. The cleaning elements 4 are isosceles triangles. Their sharp, triangular shape helps push sludge, preventing excessive accumulation within the silo and potentially reducing clogging. A rotating rod 5 is positioned between two adjacent cleaning elements 4. The electrical components in this solution are controlled by a matching external controller, and the control circuit can be easily programmed by those skilled in the art. This is common knowledge in the art and is only used for reference, not for improvement. Since this invention primarily serves the purpose of protecting mechanical devices, a detailed explanation of the control method and circuit connections will not be provided.

[0023] It should be noted that the hydraulic rod 2 drives the slide 1 to move left and right repeatedly, thereby driving the cleaning part 4 to move. The movement of the cleaning part 4 pushes the sludge on the inner wall of the bottom end of the sludge silo, so that it is discharged from the discharge port. The sludge discharged from the discharge port falls into the spiral unloader for unloading until the sludge on the inner wall of the bottom end of the sludge silo is cleaned up. In addition, the connecting plate 7 can be disassembled by removing the bolts at a later time, and the equipment in the first mounting groove 8 and the second mounting groove 9 can be repaired.

[0024] Working principle: When it is necessary to clean the sludge on the inner wall of the bottom end of the sludge silo, by starting the motor 10 and the hydraulic rod 2, the motor 10 drives the rotating rod 11 to rotate, and the rotating rod 11 rotates to drive multiple worm sleeves 12 to rotate, and the worm sleeve 12 rotates to drive the worm wheel 13 to rotate, and the worm wheel 13 rotates to drive the rotating rod 5 to rotate, and the rotating rod 5 rotates to drive multiple crushing knives 6 to rotate. The crushing knife 6 breaks the sludge into small pieces, making it convenient for the slide 1 to push the sludge to avoid blockage of the discharge port and affect the discharge. The hydraulic rod 2 drives the slide 1 to move left and right repeatedly, thereby driving the cleaning part 4 to move left and right, and the cleaning part 4 moves to push and scrape off the sludge on the inner wall of the bottom end of the sludge silo, so that it is discharged from the discharge port. The sludge discharged from the discharge port falls into the screw unloader for unloading until the sludge on the inner wall of the bottom end of the sludge silo is cleaned up and the pushing is stopped.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
