Description

Technical Field

[0001] The utility model relates to the technical field of sludge aerobic composting, in particular to a sludge aerobic composting device with an automatic turning function. Background Art

[0002] Composting is a method of promoting the degradation and conversion of organic matter in fertilizers by centrally piling and disposing of fertilizers before fermentation. The essence of a composting device is to centrally pile up fertilizers in the process and to perform simple impurity removal on the fertilizers at the same time. For example, a sludge aerobic composting device with publication number CN214457676U includes a mixing box. Through the setting of a vibrating net, the sludge aerobic composting device has the effect of removing plastic bags and large pieces of garbage. Through the coordinated setting of a reciprocating motor, a rotor, a block, a reciprocating spring, a vibrating net, a screening net and screening nails, garbage bags and large pieces of garbage can be blocked during use and the sludge can be made to fall by vibration, thereby achieving the purpose of treating impurities in the sludge. However, the sludge aerobic composting device still has the following disadvantages during actual use:

[0003] When the sludge is poured into the treatment tank for composting, the sludge is prone to caking and sticking. Therefore, during the processing, there is only a structure for stirring the sludge, but lacks the function of shaking it apart. In addition, a certain amount of gas will be generated during the stirring process. The traditional composting device is not convenient for releasing the gas generated by the stirring in time, which in turn affects the subsequent processing. In view of the above problems, it is urgently necessary to carry out innovative design based on the original sludge aerobic composting device. Utility Model Content

In addition, a certain amount of gas will be generated during the stirring process. The traditional composting device is not convenient for timely releasing the gas generated by the stirring, which further affects the subsequent processing.

[0029] When existing composting devices stir the sludge, most of them can only stir in the same direction, resulting in uneven stirring of the sludge. Figure 1-Figure 3 and Figure 5 As shown, the connecting shaft 5 and the movable shaft 10 are symmetrically distributed about the vertical axis of the processing tank 1, and the connecting shaft 5 and the movable shaft 10 rotate in opposite directions; through holes are evenly arranged on the transverse plates of the first stirring frame 6 and the second stirring frame 11, and the transverse plates of the first stirring frame 6 and the second stirring frame 11 are in close contact with the inner wall of the processing tank 1; first, the sludge and other materials to be composted are poured into the processing tank 1 from the feed port 2, and the motor 4 drives the first stirring frame 6 to rotate through the connecting shaft 5 to achieve stirring of the material. When the connecting shaft 5 rotates, the transmission shaft 7 can be driven to rotate through a pulley mechanism, and then the transmission shaft 7 drives the guide shaft 8 to rotate through another pulley mechanism, and then the movable shaft 10 is driven to rotate through two meshing gears 9, which can drive the second stirring frame 11 to rotate. Since the second stirring frame 11 rotates in opposite directions to the first stirring frame 6, comprehensive stirring of the material can be achieved.

[0030] Embodiment 2: When the existing sludge is poured into the treatment tank for composting, the sludge is prone to caking and sticking. Therefore, during the processing, there is only a structure for stirring the sludge, but there is no function of shaking it apart. Therefore, this embodiment adopts the following technical solutions, such as Figure 3 and Figure 6 As shown, the vibration mechanism includes a fixed block 12 fixed to the first stirring frame 6 and the second stirring frame 11 near one end of the processing tank 1, and the side of the fixed block 12 is in contact with the connecting block 16; the connecting block 16 is symmetrically fixed to the inner wall of the processing tank 1 at equal angles, and the distribution range of the connecting block 16 is 1 / 2 of the inner circumference of the processing tank 1; the second stirring frame 11 and the first stirring frame 6 drive the fixed block 12 to rotate synchronously when rotating, and the contact between the fixed block 12 and the connecting block 16 can drive the stirring frame to shake, which has a shaking effect on the sludge, thereby reducing its agglomeration and allowing the sludge to contact with other materials more evenly.

[0031] Embodiment 3: The existing composting device will generate a certain amount of gas during the stirring process. The traditional composting device is not convenient to release the gas generated by stirring in time, which further affects the subsequent processing.

When the fixed block 12 does not contact with the movable rod 13, the resilience of the spring can drive the movable rod 13 and the connecting plate 14 to move in the opposite direction to block the fixed cylinder 15. Therefore, intermittent pressure relief of the processing tank 1 can be achieved through the rotation of the stirring frame.
