[0001] The utility model relates to the technical field of waste discharge equipment, in particular to a waste discharge system for water-loving animals used in aquaculture. Background Art

[0002] Animal husbandry utilizes the physiological functions of domesticated animals, such as livestock and poultry, or wild animals like deer, musk deer, foxes, minks, otters, and quail, through artificial breeding and reproduction, converting plant energy, such as forage and fodder, into animal energy to produce livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal herbs.

Sealed doors are installed on the sides of the crushing box 1, the screening box 3, and the purification box 8.

[0032] The working principle of the sewage discharge system for water-loving animals provided by the present invention is as follows: when in use, first connect the feed pipe 11 to the sewage outlet through the sewage pump, and the sewage is passed into the filter box 5 through the feed pipe 11. The sewage is filtered and purified by the inclined filter screen 21 provided in the filter box 5, and the solid-liquid separation is also achieved. The liquid falls to the bottom of the filter box 5, and is passed by the water pump 9 through the water pipe 10 and the water pipe 13 to the tubular ultrafiltration membrane 14 in the filter box 5 for secondary ultrafiltration purification, so that the treated water has better quality and can be used for reclaimed water reuse, thereby improving the use of water resources. The ultraviolet sterilization lamp 16 is used to sterilize the water after ultrafiltration, further improving the purification effect. The solid debris is fed into the screening box 3 through the feeding pipe 12 and falls onto the screen 24 for screening, so as to separate the solid dirt and the dead individuals. During screening, the rotation of the motor 29 drives the rotation of the rotating shaft 22, and the rotation of the rotating shaft 22 drives the rotation of the cam 23. As the cam 23 rotates, its convex part contacts the screening frame 25, causing the screening frame 25 to move upward. The upward movement of the screening frame 25 squeezes the slide 34 through the L-shaped connecting rod 28, and the slide 34 The shaking spring 31 is squeezed to shrink the telescopic rod 30. As the cam 23 rotates and its flat part contacts the screening frame 25, the elastic force of the shaking spring 31 pushes the slide plate 34 downward. The downward movement of the slide plate 34 drives the screening frame 25 downward through the L-shaped connecting rod 28, so that the screen 24 can shake up and down, avoiding the dead individuals from being stuck on the screen 24 during the screening process. The solid dirt after screening falls to the bottom of the screening box 3, and the dead individuals are passed into the crushing box 1 through the feeding pipe 27, so that the bodies of the dead individual animals can be separated from the solid pollutants, avoiding the influence of the dead individual animals. In order to make fertilizer, for the dead individuals that fall into the crushing box 1, the rotation of the motor 2 36 drives the rotation of the half-tooth gear 40. Since the half-tooth gear 40 always keeps meshing with one of the two racks 38, the slide frame 37 reciprocates up and down with the rotation of the half-tooth gear 40. The up and down reciprocating motion of the slide frame 37 drives the up and down reciprocating motion of the mounting plate 33 through the intermittent rod 41, so that the crushing knife 35 crushes the dead individuals, which is convenient for the subsequent fermentation reaction treatment of the crushed corpses, thereby facilitating the harmless treatment and resource utilization of the corpses of dead individual animals.

[0033] The vibration mechanism includes a vibration spring 18, a transmission block 20 and a vibration motor 19. The lower surface of the filter box 5 is connected to the upper surface of the support frame 6 through multiple vibration springs 18. The lower surface of the filter box 5 is fixedly connected to the transmission block 20. The lower surface of the transmission block 20 is installed with a vibration motor 19. During the filtration process, the vibration of the vibration motor 19 and the vibration spring 18 causes the screen 24 to vibrate continuously, and the vibration makes the filtration smoother.

[0034] Slide grooves 39 are provided on both inner sides of the drive box 32, and the two side surfaces of the slide frame 37 are respectively inserted into the adjacent slide grooves 39. The slide grooves 39 are provided to limit the slide frame 37, so that the slide frame 37 is more stable during the up and down movement.

[0035] A discharging mechanism is also installed in the screening box 3, which includes a third motor 42, a screw rod 43, a push plate 44 and a limit rod 45. The rear end face of the screening box 3 is installed with a third motor 42, and the output end of the third motor 42 passes through the rear end face of the screening box 3 and is fixedly connected to the screw rod 43 through a coupling. A matching push plate 44 is provided on the screw rod 43. The inner rear end face of the screening box 3 is also fixedly connected to two symmetrically arranged limit rods 45, which pass through the push plate 44. Through the set discharging mechanism, when it is necessary to discharge the solid dirt in the screening box 3, the rotation of the third motor 42 drives the rotation of the screw rod 43, and the rotation of the screw rod 43 causes the push plate 44 to translate on the limit rod 45, and the solid dirt is pushed out from the sealed door of the front end face of the screening box 3, so that the discharge of solid dirt is more convenient and quick, and the labor intensity of the workers is also reduced.

[0036] A stirring mechanism is also installed in the filter box 5, and the stirring mechanism includes a fourth motor 46, a second rotating shaft 47 and a spiral stirring blade 48. The fourth motor 46 is installed on one side of the filter box 5, and the output end of the fourth motor 46 passes through the side of the filter box 5 and is fixedly connected to the second rotating shaft 47 through a coupling. The other end of the second rotating shaft 47 is rotatably connected to the inner side of the filter box 5, and the side of the second rotating shaft 47 is fixedly connected to the spiral stirring blade 48. Through the provided stirring mechanism, during use, the rotation of the fourth motor 46 drives the rotation of the second rotating shaft 47, and the rotation of the second rotating shaft 47 drives the spiral stirring blade 48 to stir, thereby avoiding precipitation in the filter box 5.
