Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a microbial degradation device for sludge. Background Technology

[0002] A sludge microbial degradation device is a specialized device for treating sludge. It decomposes organic matter in the sludge into harmless substances through the biodegradation of microorganisms, thereby achieving sludge reduction, stabilization, and harmless treatment. In the prior art, patent CN 212093719 U discloses a soil microbial degradation device, including a degradation box, a degradation pool, a mixing component, load-bearing rods, a top plate, a lighting component, a ventilation component, a drain valve, an electrical control board, and support legs. The degradation box has a degradation pool inside its end face, and the mixing component is installed inside the degradation pool. Load-bearing rods are fixedly installed around the top end face of the degradation box, and a top plate is fixedly installed on the top of the load-bearing rods. While this device can mix soil and microbial inoculants during use, the mixing method is relatively simple, the degradation time is relatively long, and the contact area between the soil and microbial inoculants is limited, ultimately reducing the degradation effect on the soil. Therefore, we propose a sludge microbial degradation device. Utility Model Content

After the addition is completed, the operator closes the box door 11 again (the locking method when the box door 11 is closed is the commonly used technology of door lock and box body connection in the prior art), and also includes a drive mechanism 7;

[0023] Drive mechanism 7 includes a fixed plate 704, a mounting rod 705, and a push plate 706. The mounting rod 705 is rotatably connected to the lower side of the front wall of the protective cover 3.

All four fixed rods 701 are provided on the upper side of the outer arc surface of the output rod 4. The outer ends of the fixed rods 701 are fixedly connected to the inner ring surface of the adjusting bearing 710. The mounting ring 702 is movably sleeved on the lower side of the outer arc surface of the rotating cylinder 703. The fixed plate 704 is provided on the front side of the outer arc surface of the adjusting bearing 710.

Through the cooperation of the fixed plate 704 and the push plate 706, the lifting plate 6 can be driven to perform vertical reciprocating motion, thereby continuously tumbling the sludge and microbial inoculum, thereby increasing the contact area between the sludge and microbial inoculum, so that the sludge and microbial inoculum can be mixed evenly, improving the degradation effect of the sludge and shortening the time spent degrading the sludge.

[0024] It also includes a control switch group 2, which is located outside the housing 1. The input terminal of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0025] Among them: a motor 10 is installed on the right side of the upper end of the protective cover 3. The lower end of the output shaft of the motor 10 is fixedly connected to the upper end of the rotating cylinder 703. The input end of the motor 10 is electrically connected to the output end of the control switch group 2. The motor 10 starts to run through the control switch group 2. The output shaft of the motor 10 drives the rotating cylinder 703 to rotate. During the rotation, the rotating cylinder 703 drives the output rod 4 to rotate through the fixed rod 701. The output rod 4 drives the stirring fan blade 5 to rotate, thereby stirring and mixing the sludge and microbial inoculum.

[0026] Among them: uprights 8 are respectively provided on the left and right sides between the top wall of the protective cover 3 and the upper end of the box 1. The two uprights 8 are slidably connected to the corresponding sliding holes provided on the lower end of the fixing plate 704. Springs 9 are respectively provided between the lower end of the fixing plate 704 and the upper end of the box 1. The springs 9 are all sleeved on the outside of the lower side of the uprights 8. The tension generated by the contraction of the springs 9 will drive the mounting ring 702 to move downward and reset through the fixing plate 704. The mounting ring 702 will drive the output rod 4 to move downward and reset through the fixing rod 701. The output rod 4 will drive the lifting plate 6 to move downward and reset.

[0027] Specifically: an air inlet pipe 13 is installed inside the air inlet on the upper side of the outer arc surface of the box 1, and an air inlet valve is connected in series in the middle of the air inlet pipe 13. An exhaust pipe 14 is installed inside the exhaust outlet on the rear side of the upper end of the box 1, and an exhaust valve is connected in series in the middle of the exhaust pipe 14. During the process of microbial degradation of sludge, the air supply equipment injects air into the interior of the box 1 through the air inlet pipe 13, and the air inside the box 1 is discharged through the exhaust pipe 14, thereby providing oxygen, promoting the growth and metabolism of aerobic microorganisms, and accelerating the degradation of organic matter in the sludge.

[0028] Among them, lifting plates 6 are respectively set in the middle part of the outer arc surface of the output rod 4. The lifting plates 6 are set at intervals with the stirring fan blades 5 at the same height. During the movement, the lifting plates 6 will continuously tumble the sludge and microbial inoculants to ensure the uniformity of the mixing of sludge and microbial inoculants.

[0029] The working principle of the sludge microbial degradation device provided by this utility model is as follows: Before use, first connect the discharge pipe 12 to the external sludge discharge pump, and then connect the air inlet pipe 13 to the external air supply equipment. During the subsequent use of the sludge microbial degradation device, the operator first climbs to the top of the chamber 1 using a ladder or other tools, then opens the chamber door 11. The external conveying equipment then adds the sludge to be degraded and the microbial inoculum into the chamber 1. After adding, the operator closes the chamber door 11 again, then opens the air inlet valve and exhaust valve, and finally leaves the chamber 1. Then, through the control of the switch group 2, the motor 10 starts running. The output shaft of the motor 10 drives the rotating drum 703 to rotate. During the rotation of the rotating drum 703... During the process, the fixed rod 701 drives the output rod 4 to rotate, which in turn drives the stirring fan blades 5 to rotate, thereby mixing the sludge and microbial inoculum. Simultaneously, through the control switch group 2, the drive motor 709 starts running. The output shaft of the drive motor 709 drives the central wheel 707 to rotate. The output shaft of the drive motor 709 and the central wheel 707 share the same central axis. When the central wheel 707 rotates, it drives the adjusting rod 711 to rotate around the axis of the central wheel 707. Because the axis of the adjusting rod 711 does not coincide with that of the central wheel 707, the adjusting rod 711 will experience lateral and vertical displacement during its circular motion. When the adjusting rod 711 rotates to the left side of the central wheel 707, the adjusting rod 711 will move through the transmission plate 70... 8. A leftward pulling force is applied to the push plate 706, causing it to rotate upward around the mounting rod 705. During this rotation, the push plate 706 exerts an upward pushing force on the fixed plate 704. The spring 9 extends, causing the fixed plate 704 to move the fixed rod 701 upward via the mounting ring 702. The fixed rod 701 then moves the lifting plate 6 upward via the output rod 4. When the adjusting rod 711 rotates to the right of the center wheel 707, it exerts a rightward pushing force on the push plate 706 via the transmission plate 708, causing it to rotate downward around the mounting rod 705. At this time, the pulling force generated by the contraction of the spring 9 moves the mounting ring 702 downward to reset via the fixed plate 704. The mounting ring 702 will... The fixed rod 701 drives the output rod 4 to move downwards and reset, which in turn drives the lifting plate 6 to move downwards and reset, thereby causing the lifting plate 6 to perform vertical reciprocating motion. During the movement, the lifting plate 6 continuously agitates the sludge and microbial inoculants, ensuring the uniformity of the mixture. During the process of microbial inoculants degrading the sludge, the air supply device injects air into the interior of the chamber 1 through the air inlet pipe 13, and the air inside the chamber 1 is discharged through the exhaust pipe 14, thereby providing oxygen, promoting the growth and metabolism of aerobic microorganisms, and accelerating the degradation of organic matter in the sludge. After the sludge degradation is completed, the drain valve is opened, and the degraded sludge in the chamber 1 is discharged through the discharge pipe 12 by the external sludge discharge pump.

[0030] It is worth noting that the drive motor 709 and motor 10 disclosed in the above embodiments can be selected as 5IK200A-AF, and the control switch group 2 is provided with control buttons corresponding one-to-one with the drive motor 709 and motor 10 for controlling their switching.
