Description

Technical Field

[0001] The invention relates to the technical field of sewage and wastewater treatment devices, and in particular to a sewage and wastewater recycling treatment system for a laying hen farm. Background Art

[0002] The laying hen farm has achieved resource utilization of wastewater through a scientific sewage and wastewater recycling system. The system first separates the solid and liquid into the wastewater and removes suspended matter. It then uses anaerobic-aerobic biological treatment technology to degrade organic matter and recover biogas as energy. The treated water can be used for on-site flushing, irrigation of farmland, etc., promoting the sustainable development of the breeding industry.

[0003] The patent with application number CN202222936482.4 discloses a purification device for laying hen farming wastewater treatment, including a wastewater treatment box for solid-liquid separation of wastewater and a collection bag for collecting solid residues. The top of the wastewater treatment box is provided with a delivery pipe connected to the wastewater source. By designing a solid-liquid separation mechanism, a plurality of spherical activated carbons for absorbing odors are arranged at the bottom of the wastewater treatment box to prevent the odor generated by the sewage from directly diffusing in the air and affecting the environment.

[0004] However, existing wastewater treatment equipment in laying hen farms generally has problems such as low flocculation and mixing efficiency and high power energy consumption. Traditional systems mostly use independent drive structures, and flocculant addition relies on static injection or single mechanical stirring. Uneven dispersion of the agent leads to prolonged reaction time and poor coagulation effect of suspended matter. At the same time, scum cleaning requires additional power sources or manual intervention. During equipment operation, the scraping mechanism is separated from the flocculation treatment link, which increases the operation and maintenance burden.

[0005] In view of this, we propose a wastewater recycling and treatment system for laying hen farms. Summary of the invention

[0029] Specifically, the air float 221 is fixedly connected to the inner bottom surface of the tank body 210 by bolts, the top of the air float 221 is tilted downward, a placement cavity 2210 for placing the dissolved air tube 222 is opened inside the air float 221, the air valve at the end of the dissolved air tube 222 is placed on the inner bottom surface of the air float 221, and the docking rod 223 is used to provide a support base point for the stirring tube 120.

[0030] Furthermore, the placement chamber 2210 in the air flotation cylinder 221 is used to provide a placement area for the air dissolving tube 222. The air valve at the end of the air dissolving tube 222 generates fine bubbles that adhere to the suspended matter, thereby driving the suspended matter to float up and form scum.

[0031] In this embodiment, Figure 8-Figure 9 As shown, the driving device 300 includes a motor 320, a reciprocating screw 330 disposed on the output shaft of the motor 320, a stamping part 350 disposed below the reciprocating screw 330, and a transmission part 370 for transmitting power.

[0032] Specifically, the stamping part 350 includes a moving frame 351 that moves left and right with the rotation of the reciprocating screw 330, a fixed tooth plate 352 that moves together with the moving frame 351, and an air cylinder 353 arranged under the moving frame 351. When the moving frame 351 moves, the gas can be stamped into the stirring tube 120 through the air cylinder 353, so that the flocculant is sprayed out from the spray valve 150 and mixed with the sewage.

[0033] Furthermore, the driving device 300 also includes a fixed frame 310 fixedly connected to the top of the tank body 210 by bolts, the motor 320 fixedly connected to the motor 320 on the top surface of the fixed frame 310 by bolts, the reciprocating screw 330 is coaxially connected to the output shaft of the motor 320, and the worm 340 is fixedly connected to the outer wall of the reciprocating screw 330 by a pin.

[0034] Furthermore, the upper and lower ends of the movable frame 351 are respectively integrally formed with a protrusion mounted on the outside of the reciprocating screw 330 and a protrusion plate connected to the protrusion shaft of the piston plate in the air cylinder 353. The outside of the air outlet pipe at the end of the air cylinder 353 is connected to an outer cover 354 mounted on the top of the stirring tube 120, and the top of the outer cover 354 is connected to a liquid inlet pipe 360 ​​for flocculant injection.

[0035] Furthermore, after the motor 320 is started, it drives the reciprocating screw 330 to rotate while driving the worm 340 to rotate. When the worm 340 rotates, it collides with the pipe wall gear 140, and drives the stirring tube 120 to rotate. At the same time, the moving frame 351 moves back and forth left and right as the reciprocating screw 330 rotates. The moving frame 351 then drives the piston plate in the gas cylinder 353 to move, and the gas is pressurized into the interior of the stirring tube 120, and then the flocculant injected from the liquid inlet pipe 360 ​​is sprayed into the interior of the cylinder 110 through the spray valve 150, and the sewage and the flocculant are fully mixed through the stirring blades 130.

[0036] In this embodiment, Fig.10 As shown, the transmission part 370 includes an end tooth 371 that rotates after contacting the movable fixed tooth plate 352 and an outer gear 372 that rotates as the end tooth 371 rotates clockwise. When the outer gear 372 rotates, it drives the scraping mechanism 400 to rotate to clean the floating slag in the slag storage ring 230.

[0037] Specifically, the transmission part 370 also includes an inner ratchet 373 arranged on the inner side of the outer gear 372, a pawl 374 rotatably connected to the inner ring wall of the outer gear 372 and in contact with the inner ratchet 373, and a transmission shaft 375 connected between the end teeth 371 and the inner ratchet 373, the end teeth 371 are meshed with the fixed tooth plate 352, and the transmission shaft 375 is rotatably connected to the inside of the fixed frame 310.

[0038] Furthermore, when the moving frame 351 moves to the left, the fixed tooth plate 352 drives the end tooth 371 to rotate clockwise, and the transmission shaft 375 drives the inner ratchet 373 to rotate. After the clockwise rotating inner ratchet 373 contacts the pawl 374, it drives the outer gear 372 to rotate one circle.

[0039] In this embodiment, Fig.11 As shown, the scraping mechanism 400 includes a fixed ring tooth 410 meshing with the external gear 372, a reinforcing ring body 420 parallel to the bottom of the fixed ring tooth 410, and a plurality of scrapers 430 regularly distributed between the fixed ring tooth 410 and the reinforcing ring body 420. The plurality of scrapers 430 block the space between the slag flow trough 211 and the slag discharge trough 231.

[0040] Furthermore, the outer gear 372 rotates one circle and conflicts with the fixed ring gear 410, thereby driving the plurality of scrapers 430 to rotate, thereby scraping the slag entering the slag storage ring 230 into the slag discharge groove 231, and the subsequent operator can directly clean the slag in the slag storage barrel 250.

[0041] Finally, it should be noted that the motor 320 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 motor 320 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.

[0042] When the wastewater recycling treatment system for laying hen farms of the present invention is used, first, the wastewater of the laying hen farm is injected into the interior of the cylinder 110 through the sewage inlet pipe 160, and the motor 320 in the driving device 300 is started to drive the reciprocating screw 330 to rotate and drive the worm 340 to rotate; When the worm 340 rotates, it contacts the pipe wall gear 140, driving the stirring pipe 120 to rotate. At the same time, the moving frame 351 moves back and forth along with the rotation of the reciprocating screw 330. The moving frame 351 then drives the piston plate in the gas cylinder 353 to move, and pressurizes the gas into the stirring pipe 120, and then the flocculant injected from the liquid inlet pipe 360 ​​is sprayed into the inside of the cylinder 110 through the liquid spray valve 150, and the sewage and the flocculant are fully mixed through the stirring blades 130; After the sewage is mixed, the suspended matter inside it and the sewage enter the interior of the air float 221. At this time, the external aerosol machine is started, and fine bubbles are generated through the air valve at the end of the air dissolving tube 222. After the suspended matter in the sewage contacts with the fine bubbles, the suspended matter is driven to move upward; Subsequently, the excess sewage overflows from the air float 221 to the inside of the tank 210. When the liquid level in the tank 210 approaches the slag guide ring 240, the floating slag first enters the slag flow trough 211 through the slag guide ring 240, and then enters the inside of the slag storage ring 230. Afterwards, when the moving frame 351 moves to the left, the fixed tooth plate 352 drives the end tooth 371 to rotate clockwise, and the transmission shaft 375 drives the inner ratchet 373 to rotate. After the clockwise rotating inner ratchet 373 contacts the pawl 374, the outer gear 372 is driven to rotate one circle. Then, the outer gear 372 rotates one circle and contacts with the fixed ring gear 410, driving the scrapers 430 to rotate, thereby scraping the floating slag entering the slag storage ring 230 into the slag discharge tank 231, and the treated sewage flows out from the liquid outlet pipe 260 and is sent to the subsequent anaerobic and aerobic treatment system.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings.
