Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, and in particular to a wastewater recycling device for slaughterhouses. Background Technology

[0002] Existing wastewater recycling devices include various technologies, mainly divided into physical, chemical, and biological methods. Among them, physical methods use screens to treat larger objects, chemical methods remove pollutants through chemical precipitation and redox reactions, and biological methods use traditional treatment processes such as biofilms to biodegrade organic matter.

[0003] In the physical treatment of wastewater in slaughterhouse workshops, animal hair easily clogs the screens when passing through them, making them difficult to clean and time-consuming. Furthermore, the wastewater in slaughterhouses contains a large amount of blood and animal fat, which, if not treated in a timely and thorough manner, can easily form a layer of grease in subsequent water pipes, causing blockages. In addition, the treated grease wastewater is not effectively collected, resulting in secondary pollution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater recycling device for slaughterhouses.

This is existing technology and will not be described in detail.

[0021] The hair removal assembly includes a rotating roller 16, with a cleaning brush slidably connected to its outer side for better hair removal from the grating. A collection trough 19 is installed on the outer side of the wastewater tank 1, and a collection opening is provided on the side wall of the collection trough 19. Two slide rails 17 are fixedly connected to the upper side of the wastewater tank 1, and the rotating roller 16 passes through the slide rails 17. Both ends of the rotating roller 16 are fixedly connected to transmission gears 9. Two racks 13 are fixedly connected to the upper side of the wastewater tank 1, and the two racks 13 are respectively meshed with the transmission gears 9. A reciprocating screw 8 is rotatably connected to the upper side of the wastewater tank 1, and a reciprocating sleeve 28 is threadedly connected to the outer side of the reciprocating screw 8. The reciprocating sleeve 28 and the wastewater tank 1 are connected to the reciprocating sleeve 28.

The outer side of the reciprocating screw 8 is fixedly connected to the first gear 23. The side wall of the wastewater tank 1 is rotatably connected to the drive shaft. The outer side of the drive shaft is fixedly connected to the third gear 25. The side wall of the wastewater tank 1 is rotatably connected to two second gears 24, and the two second gears 24 mesh with each other.

[0022] In this invention, when wastewater needs to be recycled, the specific operation is as follows: Wastewater is poured from the screen 18 into the wastewater tank 1. Hair in the wastewater remains on the upper side of the screen 18. Then, the wastewater entering the wastewater tank 1 enters the oil separator 10 through the outlet 15, and finally enters the drainage treatment assembly. When the treatment begins, the motor 2 is started first. The motor 2 drives the second bevel gear 22 to rotate through the transmission rod 27. The second bevel gear 22 drives the connecting rod to rotate through the first bevel gear 21. The transmission shaft drives the third gear 25. The third gear 25 rotates, and the first gear 23 rotates through the second gear 24, which in turn drives the reciprocating screw 8 to rotate. The reciprocating sleeve 28 on the reciprocating screw 8 reciprocates. Under the restriction of the transmission gear 9 and the rack 13, the rotating roller 16, which moves with the reciprocating sleeve 28, rolls back and forth on the grid 18 to achieve the effect of cleaning the animal hair remaining on the grid. The cleaned hair falls into the collection trough 19. When the collection trough 19 is almost full, the collection port on the side wall of the collection trough 19 is opened to process the hair in the collection trough 19.

[0023] During the above operation, the transmission rod 27 simultaneously drives the conveyor belt 14. The oil drain plate 20 on the conveyor belt 14 moves with the conveyor belt 14 to clean the oil floating on the upper layer of the oil separator 10. The oil pushed by the oil drain plate 20 flows into the sewage trough 12. The oil in the sewage trough 12 flows into the sewage tank 5 through the sewage outlet 6. Then, the wastewater entering the sewage tank 5 can be treated accordingly.
