Description

Technical Field

[0001] This invention relates to the field of feather processing technology, and in particular to a device for purifying and treating wastewater from feather washing. Background Technology

[0002] Feathers typically refer to the feathers and down of poultry such as geese, ducks, and swans. Feathers are lightweight, warm, and have a pleasant feel against the skin, making them widely used in textiles, clothing, and bedding. However, due to the diverse environments in which feathers grow and the wide variety of feather species, the long acquisition and transportation process results in feathers having a strong odor and harboring a large number of bacteria on their surface. Feathers must undergo washing before use, and the quality of the washed feathers must be rigorously tested. Washing feathers generates a large amount of wastewater, which must be treated before discharge to prevent significant pollution to the environment. The wastewater from washing feathers contains a large number of fine, long downy hairs that can be recycled to make filter cartridges and other products, demonstrating significant recycling value.

[0003] A search revealed Chinese patent publication number CN108558073A, which discloses a wastewater treatment device for feather processing. The device includes a discharge pipe connected to a sedimentation tank, which in turn is connected to a flocculant tank. The sedimentation tank contains a first stirring rod connected to a first motor. A sludge zone is located at the bottom of the sedimentation tank, with a sludge-leakage plate above it. The sedimentation tank has an outlet connected to a collection box via a water outlet pipe. The collection box contains a feather filter and a drain outlet at its lower end. The aforementioned patent uses a feather filter to collect down, which makes it inconvenient to distinguish and collect finer, longer down feathers with greater economic value.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0032] Example 1:

[0033] A device for purifying and treating wastewater from feather washing, such as Figure 1-6As shown, the system includes an initial settling zone 1 and a conveyor belt assembly 10. Wastewater undergoes initial settling in the settling zone 1, where fine impurities and long fibers float on the surface. A retrieval cover 8 is bolted above the initial settling zone 1 to prevent the spread of foul odors from the wastewater. Multiple support frames 12, trapezoidal hollow tubes, are bolted to one side of the conveyor belt assembly 10. The conveyor belt assembly 10 can be a chain or a belt. Multiple transmission gears 15 are rotatably connected inside the support frames 12, meshing with each other. A rotating plate 16 is bolted to one end of each transmission gear 15, rotatably connected to the support frame 12 and located outside the support frame 12. Multiple retrieval bars 1 are fixedly connected to one end of the rotating plate 16. 9. The retrieval bar 19 is a thin plastic strip that can retrieve the thin, long fibers floating on the upper layer when passing through the upper layer of the initial settling zone 1. A fiber-pushing component is fixedly connected to one side of the rotating plate 16. The fiber-pushing component can push the fibers above the retrieval bar 19 to the tip of the retrieval bar 19. A fiber-collecting plate 20 and a rack 11 are bolted to one side of the retrieval cover plate 8. The fiber-collecting plate 20 is an inclined anti-slip metal plate with comb teeth at one end that are spaced the same as the diameter of the retrieval bar 19. It can comb down the fibers from above the retrieval bar 19 when it rotates and passes through. One side of the rack 11 is connected to the transmission gear 15. When the transmission gear 15 rotates with the support block 12 to the lower side, one side meshes with the rack 11, causing the rotating plate 16 and the retrieval bar 19 to rotate when moving, thereby improving the retrieval effect.

[0034] The pusher assembly includes a scissor lift assembly 17 and a pusher plate 18. The scissor lift assembly 17 is a small electric scissor lift. One end of the scissor lift assembly 17 is bolted to the rotating plate 16. One end of the pusher plate 18 is slidably connected to the scissor lift assembly 17 and the retrieval bar 19. When the scissor lift assembly 17 is working, the pusher plate 18 moves back and forth, pushing the down towards the front end of the retrieval bar 19.

[0035] To solve the problem of cleaning the retrieved down; such as Figure 1-6 As shown, a feeding funnel 13 is bolted to one side of the lint-collecting plate 20, and a cleaning nozzle 14 is bolted to one end of the feeding funnel 13. A cleaning tank 9 is bolted to the bottom of the feeding funnel 13. A stirring component is located at one end of the cleaning tank 9. The lint accumulated on the lint-collecting plate 20 falls into the cleaning tank 9 through the feeding funnel 13. The cleaning nozzle 14 can spray water downwards to flush the lint into the cleaning tank 9. The sprayed liquid can be a cleaning agent for removing grease. A pipe switch 21 is bolted to one end of the cleaning tank 9. A filter screen is located on the outlet side of the cleaning tank 9 to prevent the lint from flowing out after cleaning.

[0036] To address the issues of impurity flotation and filtration in the initial settling zone 1; such as... Figure 1-6As shown, a water inlet pipe 6 is bolted to one side of the initial settling zone 1, and an aeration pump 7 is bolted to one end of the water inlet pipe 6. The aeration pump 7 injects fine air bubbles into the liquid to help the fine and long fibers float and make them easier to retrieve. One side of the initial settling zone 1 and the pipe switch 21 are fixed to the water spray pipe 24 by pipe bolts. There are multiple spray nozzles on one side of the water spray pipe 24.

[0037] One side of the water spray pipe 24 is bolted to the bar screen filter area 2. The bar screen filter area 2 is cylindrical. One side of the bar screen filter area 2 is bolted to a roller motor 22. The power output end of the roller motor 22 is connected to a filter roller 23. The filter roller 23 is a metal filter screen. When the water spray pipe 24 sprays water downward in the middle of the filter roller 23, the filter roller 23 filters out fine impurities. The two sides of the filter roller 23 are slidably connected to the inside of the bar screen filter area 2. The filter roller 23 rotates inside the bar screen filter area 2 under the drive of the roller motor 22. An acidification water inlet pipe 25 is fixedly connected to the bottom of the bar screen filter area 2.

[0038] To improve the biodegradability of wastewater and remove impurities such as COD; such as Figure 1-6 As shown, one end of the acidification inlet pipe 25 is bolted to the acidification zone 3, and the other end of the acidification zone 3 is bolted to the acidification outlet pipe 26. The acidification zone 3 has the function of acidification and flocculation, which can accelerate the degradation of organic matter in sewage. One end of the acidification outlet pipe 26 is bolted to the water pump 27, and one side of the water pump 27 is bolted to the aeration zone 4. The aeration zone 4 adopts biological aeration treatment technology, which degrades impurities such as COD in sewage through microorganisms. The output end of the water pump 27 is fixedly connected to multiple outlet pipes 29. The water pump 27 passes the acidified sewage into the aeration zone 4 for treatment. The outlet pipes 29 drain water from the bottom to the top, and one end of the outlet pipe 29 is bolted to the check valve 31.

[0039] One end of the check valve 31 is fixedly connected to the recovery tank 32 via the pipe switch 21. The recovery tank 32 is used to recover wastewater containing a large amount of mud during backwashing. When backwashing is not performed, the pipe switch 21 is closed. The upper part of the recovery tank 32 is fixedly connected to the acidification outlet pipe 26 via the pipe switch 21. There is a filter screen in the recovery tank 32 to filter mud. When the liquid in the recovery tank 32 is close to overflowing, the pipe switch 21 is opened so that the water pump 27 can draw the liquid in the recovery tank 32.

[0040] An aeration pump 28 is fixedly connected above the aeration zone 4. Multiple aeration pipes 30 are fixedly connected to one end of the aeration pump 28. The aeration pump 28 sprays gas from the bottom through the aeration pipes 30 to aerate, promote microbial growth and increase degradation effect.

[0041] A transmission box 34 is fixedly connected to one end of the aeration zone 4. A flip motor 33 is fixedly connected to one end of the transmission box 34. A filter plate 36 is rotatably connected to one end of the flip motor 33. The filter plate 36 is a square plate with rounded sides. It is preferably made of polystyrene, which is conducive to the growth of microorganisms. When the flip motor 33 is working, it can drive the filter plates 36 on both sides to rotate through the transmission box 34. A sealing groove 37 is fixedly connected inside the aeration zone 4. The sealing groove 37 assists in the stability and sealing of the filter plate 36 in the horizontal state, so that the liquid must pass through the filter plate 36. One side of the sealing groove 37 is slidably connected to the filter plate 36.

[0042] In this embodiment, the sewage undergoes initial sedimentation in the settling zone 1. At this time, fine impurities and long fibers float on the surface of the water. The retrieval cover 8 prevents the spread of foul odors from the sewage. The support frame 12 is a trapezoidal hollow tube. The conveyor belt assembly 10 can be a chain or a belt. The transmission gears 15 mesh with each other. The rotating plate 16 is rotatably connected to the support frame 12 and is located outside the support frame 12. The retrieval strip 19 is a long plastic strip that can retrieve the long fibers floating on the upper layer when passing through the upper layer of the initial settling zone 1. The fiber-pushing assembly can push the fibers above the retrieval strip 19 to the tip of the retrieval strip 19. The fiber-removing plate 20 is an inclined metal plate with comb teeth at one end that are spaced the same as the diameter of the retrieval strip 19. It can comb the fibers from above the retrieval strip 19 when it rotates and passes by. When the transmission gear 15 rotates with the support block 12 to the lower side, one side meshes with the rack 11, causing the rotating plate 16 and the retrieval strip 19 to rotate when moving, thus improving the retrieval effect.

[0043] The pile of fluff on the board 20 falls into the cleaning tank 9 through the feeding funnel 13. The cleaning nozzle 14 can spray water downwards to flush the fluff into the cleaning tank 9. The sprayed liquid can be a cleaning agent for removing grease. There is a filter screen on one side of the outlet of the cleaning tank 9 to prevent the fluff after cleaning from flowing out.

[0044] Aeration pump 1 injects tiny air bubbles into the liquid to help the fine fluff float to the surface for easy retrieval; spray pipe 24 has multiple nozzles on one side.

[0045] The grid filter area 2 is cylindrical, and the filter roller 23 is a metal filter screen. When the water spray pipe 24 sprays water downward in the middle of the filter roller 23, the filter roller 23 filters out fine impurities.

[0046] Acidification zone 3 has the function of acidification and flocculation, which can accelerate the degradation of organic matter in wastewater. Aeration zone 4 adopts biological aeration treatment technology, which degrades impurities such as COD in wastewater through microorganisms. Water pump 27 passes the acidified wastewater into aeration zone 4 for treatment, and water outlet pipe 29 drains water from the bottom to the top.

[0047] The recycling tank 32 is used to recycle wastewater containing a large amount of mud during backwashing. When backwashing is not performed, the pipeline switch 21 is closed. The recycling tank 32 has a filter screen to filter mud. When the liquid in the recycling tank 32 is close to overflowing, the pipeline switch 21 is opened so that the water pump 27 can draw the liquid in the recycling tank 32.

[0048] The aeration pump 28 sprays gas from the bottom through the aeration pipe 30 to aerate, promote microbial growth and increase degradation effect; the filter plate 36 is a square plate with rounded sides, preferably made of polystyrene to facilitate microbial growth. When the flip motor 33 is working, it can drive the filter plates 36 on both sides to rotate through the transmission box 34. The sealing groove 37 assists in the stability and sealing of the filter plate 36 in the horizontal state, so that the liquid must pass through the filter plate 36.

[0049] Example 2:

[0050] A device for purifying and treating wastewater from feather washing, such as Figure 1-6 As shown, in order to solve the problem of cleaning the filter plate 36, this embodiment makes the following improvements based on embodiment 1: The aeration zone 4 is bolted to the water storage tank 5, which stores treated and usable clean water that can be introduced into work such as greening irrigation. One end of the water storage tank 5 is fixedly connected to a return water pipe 35, and one end of the return water pipe 35 is connected to a high-pressure pump. One end of the return water pipe 35 is fixedly connected to multiple back flush pipes 38, and one end of the back flush pipes 38 is fixedly connected to multiple flushing nozzles 39. The high-pressure pump sprays the liquid onto the filter plate 36 through the flushing nozzles 39. After one side of the filter plate 36 is cleaned, it can be rotated to clean the other side, thereby improving the utilization rate of the filter plate 36.
