Description

Technical Field

[0001] The invention relates to the technical field of poultry excrement treatment, and in particular to an integrated device for harmless treatment of livestock and poultry excrement solid waste and resource recovery. Background Art

[0002] The harmless treatment and resource recycling of livestock and poultry manure solid waste is an environmentally friendly and sustainable technical method. Through advanced treatment technologies such as aerobic composting fermentation and anaerobic fermentation, the organic matter in livestock and poultry manure is converted into stable humus to achieve harmless treatment. At the same time, these treatment processes can also produce valuable resources such as organic fertilizers, biogas and biodiesel, realizing resource recovery and recycling.

[0003] The patent with application number CN201920781915.9 discloses a harmless treatment equipment for livestock and poultry manure, including a fixed frame, a fermentation tank, a first rotating shaft, a stirring rod, a stirring motor, an electric exhaust valve, a radar level gauge, a pressure sensor, a control panel and a microcontroller. The fermentation tank is fixed on the inner wall of the fixed frame, and the first rotating shaft is rotatably connected to the inside of the fermentation tank through a bearing. The stirring rod is symmetrically fixed on the outside of the first rotating shaft, and the microcontroller is electrically connected to the inside of the control panel. This harmless treatment equipment for livestock and poultry manure greatly improves the fermentation speed of manure, and facilitates the discharge of manure, which is convenient for people to use.

[0004] In the technical field of livestock and poultry manure treatment, the primary problem lies in the singleness of the stirring mechanism, which leads to insufficient mixing of the manure during the stirring process, thus affecting the uniformity of fermentation; secondly, the oxygen supply system mainly relies on the fixed air inlet duct on the top of the fermentation tank. This method lacks flexible oxygen concentration control and is prone to cause excessive oxidation of the internal environment, reducing the activity of microorganisms and slowing down the fermentation rate; in addition, the post-processing process is cumbersome, including multiple steps such as crushing and screening, which not only increases the processing time, but also increases the overall processing cost.

[0005] In view of this, we propose an integrated device for harmless treatment and resource recovery of livestock and poultry manure solid waste. Summary of the invention

[0068] Furthermore, when the tube wall cam shaft 312 on the outer wall of the rotating tube body 311 rotates, it also moves in the cam groove 3310, thereby driving the telescopic sleeve 331 to move up and down, and then driving the outer tube body 321 to move up and down, so that the stirring blade 322 can also move up and down when rotating.

[0072] In this embodiment, Fig.13 As shown, the screening device 500 includes a rotating rod 510, a movable horizontal plate 512 that reciprocates forward and backward as the rotating rod 510 rotates, and a filter screen 514 disposed inside the openings at both ends of the movable horizontal plate 512;

At this time, the rotating rod 510 will rotate together with the docking shaft 410, and the arc gear 511 will respectively contact with the two docking tooth plates 513, thereby driving the movable cross plate 512 to move back and forth as a whole, thereby screening the feces above the filter screen 514.

[0075] Finally, it should be noted that the drive motor 210 involved in the present invention is a universal standard part or a part known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, the drive motor 210 is connected to the external power supply through a wire. The specific connection method should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection methods are all well-known technologies in the field.

[0076] When the integrated device for harmless treatment of livestock and poultry manure solid waste and resource recovery of the present invention is used, first, the driving motor 210 is started, and the worm 220 on the output shaft drives the driving gear 230 and the worm wheel 240 to rotate, thereby driving the feeding auger 250 to rotate, and then a sufficient amount of livestock and poultry manure is sent into the fermentation tank 110;

[0077] As the driving gear 230 rotates, it contacts the tube end gear 314 in the rotating part 310, driving the tube end gear 314 and the rotating tube body 311 to rotate, thereby driving the entire stirring part 320 to rotate;

When the outer sleeve body 321 moves down, the external oxygen can stop being sent to the fixed tank body 111.

[0080] After the livestock and poultry manure fermentation is completed, the output direction of the driving motor 210 is changed, and the rotation direction of the docking shaft 410 is changed, and then the rotation direction of the two sets of connecting pipe bodies 430 together with the internal spiral conveying plate 450 is changed, so that the livestock and poultry manure in the fixed tank body 111 is transported to the inside of the recovery box 120;

[0081] After passing through the guide part 130, the feces falls onto the filter screen 514 in the screening device 500. At this time, the rotating rod 510 rotates together with the docking shaft 410, and the arc gear 511 respectively contacts the two docking tooth plates 513, thereby driving the movable horizontal plate 512 to move back and forth as a whole, so that the feces above the filter screen 514 are screened.

[0082] Subsequently, the operator opens the sealing cover plate 140 and takes out the feces after vibration screening from the recovery box 120 .
