Description

Technical Field

[0001] The present invention relates to the technical field of poultry manure treatment, and specifically, to an integrated device for harmless treatment and resource recovery of livestock and poultry manure solid waste. Background Technique

[0002] The harmless treatment and resource recovery 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 the application number CN201920781915.9 discloses a livestock and poultry manure harmless treatment device, including a fixed frame, a fermentation tank, a first rotating shaft, stirring rods, a stirring motor, an electric exhaust valve, a radar level gauge, a pressure sensor, a control panel, and a microcontroller. The inner wall of the fixed frame is fixed with a fermentation tank. The inside of the fermentation tank is rotationally connected with a first rotating shaft through bearings. Stirring rods are symmetrically fixed on the outside of the first rotating shaft. The control panel is electrically connected with a microcontroller inside. This livestock and poultry manure harmless treatment device greatly improves the fermentation speed of manure and is convenient for discharging manure, facilitating people's use.

[0004] In the technical field of livestock and poultry manure treatment, the primary problem lies in the singularity of the stirring mechanism, which leads to insufficient mixing of manure during the stirring process, thereby affecting the uniformity of fermentation. Secondly, the oxygen supply system mainly relies on the fixed air inlet pipe at the top of the fermentation tank. This method lacks flexible oxygen concentration regulation, easily causes excessive oxidation of the internal environment, reduces the activity of microorganisms, and slows down the fermentation speed. In addition, the post-treatment process is cumbersome, including multiple steps such as crushing and screening, which not only increases the treatment time but also raises the overall treatment 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

[0062] Furthermore, the top end of the rotating tube body 311 is rotatably connected to the inner top surface of the fixed tank body 111, and a plurality of groups of regularly distributed air outlet grooves 3110 that penetrate inside and outside are opened on the outer wall of the rotating tube body 311, and a plurality of groups of regularly distributed limiting slide grooves 3111 are opened on the outer wall of the rotating tube body 311, and the tube wall cam 312 is welded and fixed to the outer wall of the rotating tube body 311, and the top tube wall of the rotating tube body 311 is sleeved with a tube end gear 314 that meshes with the driving gear 230, and the tube bottom scraper 315 is rotatably connected to the top surface of the material blocking plate 113, and the bottom end pipe mouth of the air inlet pipe 340 extends to the interior of the rotating tube body 311.

[0063] Further, when the driving gear 230 rotates, it will contact the pipe end gear 314 in the rotating part 310, driving the pipe end gear 314 and the rotating pipe body 311 to rotate, and then driving the entire stirring part 320 to rotate. The air outlet groove 3110 is used to provide an interval for the discharge of oxygen, the limit sliding groove 3111 is used to limit the interval of the up and down movement of the stirring part 320, and the pipe bottom scraper 315 is used to scrape the feces towards the structure in the discharging device 400 when rotating, ensuring that the feces can be discharged cleanly.

[0064] In this embodiment, as Figures 10-11 shown, the stirring part 320 includes an outer sleeve pipe body 321 sleeved on the outside of the rotating pipe body 311 and a number of stirring blades 322 regularly distributed on the outer wall of the rotating pipe body 311 and integrally wavy. Communication grooves 3210 are opened below the upper concave parts of the stirring blades 322 on the outer wall of the outer sleeve pipe body 321;

[0065] Specifically, the telescopic part 330 includes a telescopic sleeve 331 and a limit ring strip 333 for limiting the rotation interval of the rotating pipe body 311. A cam groove 3310 for providing a moving interval for the pipe wall convex shaft 312 is opened on the inner barrel wall of the telescopic sleeve 331.

[0067] Further, the telescopic sleeve 331 is slidably connected up and down inside the plate surface limit groove 1120. A barrel wall convex strip 332 for limiting the moving interval of the telescopic sleeve 331 is integrally formed on the outer wall of the telescopic sleeve 331. The bottom surface of the limit ring strip 333 abuts against the top surface of the outer sleeve pipe body 321.

[0068] Further, when the pipe wall convex shaft 312 on the outer wall of the rotating pipe body 311 rotates, it also moves inside the cam groove 3310, driving the telescopic sleeve 331 to move up and down, and then driving the outer sleeve pipe body 321 to move up and down, so that the stirring blades 322 can also move up and down when rotating. When the outer sleeve pipe body 321 moves up to the maximum height, the communication groove 3210 is connected to the air outlet groove 3110, and external oxygen is sent into the inside of the fixed tank body 111 through the air inlet pipe 340. When the outer sleeve pipe body 321 moves down, the external oxygen can stop being delivered into the fixed tank body 111.

[0069] In this embodiment, as Figure 12 shown, the discharging device 400 includes a docking shaft 410 and a communication pipe body 430 for sending feces from the fermentation tank 110 to the recycling box 120;

[0070] Specifically, the top end of the docking shaft 410 is clamped and fixed to the central axis of the tube bottom scraper 315. An end gear 420 is fixed on the outer side wall of the docking shaft 410 through a pin. One end of the connecting pipe body 430 is rotatably connected to the bottom surface of the material blocking plate 113, and the other end is rotatably connected to the top surface of the recycling box 120. A pipe wall gear 440 meshing with the end gear 420 is welded on the outer side wall of the connecting pipe body 430. A spiral conveyor plate 450 is welded and fixed inside the connecting pipe body 430, and the inner side wall of the spiral conveyor plate 450 abuts against the table top column 132.

[0071] Further, when the docking shaft 410 rotates, it will drive the end gear 420 to rotate. After contacting the pipe wall gear 440 on the outer side wall of the connecting pipe body 430, it will drive the connecting pipe body 430 to rotate, so that the feces are sent into the recycling box 120 through the rotating spiral conveyor plate 450.

[0072] In this embodiment, as Figure 13 shown, the screening device 500 includes a rotating rod 510, a moving cross plate 512 that moves back and forth before and after as the rotating rod 510 rotates, and a filter screen 514 arranged inside the open ends at the front and rear ends of the moving cross plate 512;

[0073] Specifically, the top end of the rotating rod 510 is coaxially connected to the bottom end of the docking shaft 410.

A plate end cam 5120 that is slidably connected to the box wall rib 121 is welded at the bottom corner of the moving cross plate 512. Two symmetrically arranged docking toothed plates 513 are clamped at the slot in the center of the moving cross plate 512, and both of the two docking toothed plates 513 mesh with the arc gear 511.

[0074] Further, after the feces pass through the guiding part 130, they fall above the filter screen 514 in the screening device 500. At this time, the rotating rod 510 will rotate together with the docking shaft 410. During the process of the arc gear 511 contacting the two docking toothed plates 513 respectively, it drives the entire moving cross plate 512 to move back and forth left and right, so as to screen 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 general standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle place of this device, the drive motor 210 is connected to an external power supply through a wire. The specific connection means should refer to the working principle of the present invention. The electrical components are electrically connected in accordance with the sequential working order, and the detailed connection means are all well-known technologies in the art.

[0076] When the integrated device for harmless treatment and resource recovery of livestock and poultry manure solid waste of the present invention is in use, first, start the drive motor 210, drive the drive gear 230 and the worm gear 240 to rotate through the worm 220 on the output shaft, and drive the feed auger 250 to rotate, thereby feeding a sufficient amount of livestock and poultry manure into the interior of the fermentation tank 110;

[0077] As the drive gear 230 rotates, it will come into contact with the pipe end gear 314 in the rotating part 310, and drive the pipe end gear 314 and the rotating pipe body 311 to rotate, thereby driving the entire stirring part 320 to rotate;

[0078] At this time, when the pipe wall convex shaft 312 on the outer side wall of the rotating pipe body 311 rotates, it also moves in the cam groove 3310, and drives the telescopic sleeve 331 to move up and down, thereby driving the outer sleeve pipe body 321 to move up and down, so that the stirring blade 322 can also move up and down while rotating;

[0079] When the outer sleeve pipe body 321 moves up to the maximum height, the communication groove 3210 communicates with the air outlet groove 3110, and oxygen from the outside is sent into the interior of the fixed tank body 111 through the air inlet pipe 340. When the outer sleeve pipe body 321 moves down, the oxygen from the outside can stop being sent into the fixed tank body 111;

[0080] After the livestock and poultry manure is fermented, change the output direction of the drive motor 210, and drive the rotation direction of the docking shaft 410 to change, so that the rotation directions of the two groups of communicating pipe bodies 430 and the spiral conveyor plate 450 inside are changed, thereby transporting the livestock and poultry manure in the fixed tank body 111 into the interior of the recycling box 120;

[0081] The manure falls above the filter screen 514 in the screening device 500 after passing through the guiding part 130. At this time, the rotating rod 510 will rotate together with the docking shaft 410, and drive the entire moving cross plate 512 to move left and right reciprocally during the process of abutting against the two docking tooth plates 513 through the arc-shaped gear 511, so as to screen the manure above the filter screen 514;

[0082] Subsequently, the operator opens the sealing cover plate 140 and takes out the vibration-screened manure from the recycling box 120.
