Description

Technical Field

[0002] Sludge is the product of sewage treatment. It is an extremely complex inhomogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content, high organic matter content, easy to decompose and stink, and fine particles, small specific gravity, and colloidal liquid. During the treatment process, the sludge needs to be transported to other stacking points, so a sludge conveying device is needed. The existing sludge conveying device is not convenient to control the flow rate of the feed port during feeding.

A third motor 17 is fixed on the left side of the conveyor box 1, and the output end of the third motor 17 is connected to the driving wheel 18, and the two ends of the driving wheel 18 are meshed and connected with a driven wheel 19, and the driven wheel 19 is fixed on the left side of the screw rod 20, and the screw rod 20 is rotatably connected to the inner side of the conveyor box 1, and a movable plate 21 is threadedly connected to the screw rod 20, and the lower part of the movable plate 21 The movable plate 21 is slidably connected with a guide rod 22, and the guide rod 22 is fixed to the inner bottom of the conveying box 1, and a cross bar 23 is fixed on the movable plate 21. A mud pushing mechanism 24 for removing mud inside the aggregate bin 11 is installed at both ends of the cross bar 23. The mud pushing mechanism 24 includes a fixed plate 2401, a second mud pushing plate 2402 and a limiting plate 2403. The fixed plate 2401 is fixed to both ends of the cross bar 23, and the second mud pushing plate 2402 is rotatably connected below the fixed plate 2401. At the same time, a limiting plate 2403 is fixed to the left side of the fixed plate 2401. The fixed plate 2401, the second mud pushing plate 2402 and the limiting plate 2403 are each provided with two groups, and they are symmetrically arranged. At the same time, the second mud pushing plate 2402 and the limiting plate 2403 are snap-fitted and connected. The third motor 17 drives the driving wheel 18 to rotate and drives the two sets of driven wheels 19 and the screw rod 20 to rotate. The rotation of the screw rod 20 drives the movable plate 21 threadedly connected thereto to move to the right side of the screw rod 20, and drives the cross bar 23 and the fixed plates 2401 at both ends of the cross bar 23 to move to the right inside the collecting bin 11, and cooperates with the limiting plate 2403 on the fixed plate 2401 to resist the second mud pushing plate 2402 to push the sludge collapsed and scattered from both ends of the conveyor belt 10 inside the collecting bin 11 to the discharge port 8 on the right side of the conveying box 1, so as to facilitate the cleaning of the collapsed and scattered sludge, reduce the inconvenience caused by manual cleaning, and improve practicality. When the screw rod 20 drives the movable plate 21, the cross bar 23 and the fixed plate 2401 to move to the left side of the collecting bin 11,The second mud pusher 2402 at the bottom of the fixed plate 2401 is subjected to the resistance of the mud inside the collecting bin 11, so that the top of the second mud pusher 2402 rotates so that it cannot generate thrust, which is convenient for reciprocating cleaning.

[0035] Working principle: When using the sludge conveying device with cleaning function, first discharge the sludge into the feed box 2 through the suction pipe through the feed port 3 on the top of the feed box 2, then turn on the first motor 4 outside the feed box 2 to drive the rotating roller 5 inside the feed box 2 to rotate, and when the rotating roller 5 rotates, the sludge will flow into the empty groove 6 on the surface of the rotating roller 5, and then fall onto the conveyor belt 10 inside the conveying box 1 during the rotation process, and then turn on the second motor 9 outside the conveying box 1 to drive the conveyor belt 10 to rotate to convey the sludge, so that the sludge is discharged from the discharge port 8 on the right side of the conveying box 1. During the transmission process of the conveyor belt 10, the sludge will collapse and scatter to both ends of the conveyor belt 10, and then fall into the collecting bin 11 at both ends of the bottom of the inner side of the conveying box 1. At the same time, during the transmission process of the conveyor belt 10, the scraper 15 on the right side of the conveying box 1 is pressed against the surface of the conveyor belt 10 for cleaning under the elastic force of the second spring 13 on the surface of the mounting block 12. The rubber pad 16 on the top of the scraper 15 can reduce the friction force on the conveyor belt 10 and improve its service life. When sludge adheres to the inside of the empty groove 6 on the surface of the rotating roller 5 and affects the transmission, the telescopic rod 701 inside the rotating roller 5 is opened to drive the trapezoidal block 702 to move to the right side and press against the trapezoidal plate 704, driving the trapezoidal plate 704 and the first mud pushing plate 701 to extend outward to press the sludge attached to the inside of the empty groove 6 against the outside of the empty groove 6, and then the telescopic rod 701 is depressurized to drive the trapezoidal block 702 to shrink and separate from the trapezoidal plate 704, and the first elastic plate 706 on the fixed block 706 is pressed against the outer wall of the conveyor belt 10. The elastic force of the spring 705 drives the trapezoidal plate 704 and the first mud pushing plate 703 to retract to the bottom of the empty groove 6. When there is a lot of sludge inside the collecting bin 11, the third motor 17 on the left side of the conveying box 1 is opened to drive the driving wheel 18 to rotate clockwise, and at the same time drives the driven wheel 19 and the screw rod 20 engaged at both ends to rotate. The rotation of the screw rod 20 drives the movable plate 21 threadedly connected to it inside the conveying box 1 to move to the right side of the screw rod 20. The movable plate 21 moves to the right side and drives the cross bar 23 and the fixed plates 2401 at both ends of the cross bar 23 to move to the right side inside the collecting bin 11, and cooperates with the limiting plate 2403 to press against the second mud pushing plate 2402 rotatably connected to the bottom of the fixed plate 2401 to push the sludge to the right side of the conveying box 1 for discharge. The sludge is discharged from the outlet 8, which is convenient for cleaning the collapsed and scattered sludge. Then the third motor 17 is turned on to drive the driving wheel 18 to rotate counterclockwise, so that the driving wheel 18 drives the movable plate 21 on the screw rod 20 to move to the left. When the movable plate 21 moves to the left, it drives the cross bar 23 and the fixed plates 2401 at both ends to move to the left side of the aggregate bin 11. The second mud pushing plate 2402 at the bottom of the fixed plate 2401 is affected by the sludge resistance inside the aggregate bin 11, which drives the top of the second mud pushing plate 2402 to rotate so that the second mud pushing plate 2402 fits the sludge surface and moves to the right side of the aggregate bin 11, which is convenient for reciprocating cleaning.
