Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment and reuse, and particularly relates to a filtering and recycling device for sheepskin wool washing wastewater. Background Art

[0002] A large amount of wastewater is generated during the process of washing sheepskin wool. This kind of wastewater contains various pollutants such as lanolin, detergent, protein, and solid suspended matter, and has high chemical oxygen demand (COD) and biochemical oxygen demand (BOD). If directly discharged, it will not only cause serious pollution to the environment, but also cause great waste of water resources.

[0003] At present, although there are some treatment devices for sheepskin wool washing wastewater, most of them have problems such as poor treatment effect, difficulty in achieving efficient filtration, and low recycling rate. Moreover, when some filtering devices are in use, wool debris is likely to block the filtering device, affecting the treatment efficiency and the service life of the device, and restricting the recycling of water resources.

[0004] Therefore, it is of great practical significance to develop a device that is efficient, stable and can effectively filter and recycle wastewater. Summary of the Invention

[0056] Embodiment Two

[0057] In order to realize the filtration and collection of wool debris in the wastewater, on the basis of Embodiment One, the following scheme is added in this embodiment:

[0058] Please refer to Figure 3 , Figure 4The filter collection mechanism 7 includes a filter belt 71, a driving shaft 72, a driving motor 73 and a driven shaft 74. Both ends of the driving shaft 72 are rotatably mounted on the right side of the upper port of the processing box 2, and both ends of the driven shaft 74 are rotatably mounted on the left side of the upper port of the processing box 2. The driving shaft 72 and the driven shaft 74 are connected by the filter belt 71. The driving motor 73 is mounted on the side wall of the processing box 2, and the output shaft of the driving motor 73 is connected to one end of the driving shaft 72. The filter belt 71 is provided with a plurality of through holes arranged in a matrix. A collection box 1 9 and a collection box 2 10 are respectively provided below the left and right ends of the filter belt 71.

[0059] When in use, the waste water flowing out from the drain pipe 16 of the grading mixing box 4 falls on the filter belt 71, and the waste water leaks through the through holes on the filter belt 71 and enters the treatment box 2, and the wool and debris in the waste water will be transported to the collection box 2 10 on the right side of the treatment box 2 along the filter belt 71.

[0060] Among them, a scraping mechanism 8 is also provided at the left end of the filter belt 71, and the scraping mechanism 8 includes a brush roller 81, and both ends of the brush roller 81 are installed on the track of the upper port of the processing box 2 through a bearing seat 82; one end of the brush roller 81 is connected to a belt 85 wheel 83, and one end of the driven shaft 74 is provided with a belt 85 wheel 84; the belt 85 wheel 83 and the belt 85 wheel 84 are connected through a belt 85 transmission; when in use, the driving motor 73 drives the active shaft 72 and the driven shaft 74 to rotate, and at the same time, the driven shaft 74 drives the brush roller 81 to rotate, so that the wool or debris adhered to the filter belt 71 is scraped off and falls into the collection box 9.

[0061] Both sides of the upper port of the treatment box 2 are extended outwards, and the cross section is Y-shaped, so that wastewater can fall into the treatment box 2 conveniently.

[0062] A reagent addition port 21 is provided on the side of the treatment box 2, and the interior of the treatment box 2 is a treatment chamber 23. A plurality of ribs 22 are provided at the upper port of the treatment box 2, and the ribs 22 are used to place filter screens. A recovery pipe is provided on the left side wall of the treatment box 2, and a recovery water pump 11 is provided on the recovery pipe for pumping out qualified wastewater for reuse.

[0063] The control box 12 is also included. The control box 12 is arranged on one side of the support frame 3, and the control box 12 is electrically connected to the recovery water pump 11, the water supply pump 17, the stirring motor 61 and the driving motor 73, and controls their operation.

[0064] Working principle of the present invention:

[0065] During use, the wool washing wastewater collected in the wastewater bucket 1 is pumped into the primary treatment chamber in the grading and stirring tank 4 by the water supply pump 17. At this time, the filter holes 143 on the first filter plate 141 and the second filter plate 142 are closed, making the primary treatment chamber an independent space. Then, the wastewater in the primary treatment chamber is stirred and precipitated by the primary stirring mechanism 6. Next, the filter holes 143 are opened, allowing the wastewater to enter the secondary treatment chamber, and large particle impurities are filtered out. The wastewater is stirred and precipitated again by the secondary stirring mechanism 15. The precipitated wastewater is discharged onto the filtration and collection mechanism 7 through the drain pipe 16, leaks through the through holes on the filter belt 71, and enters the treatment tank 2. The wool and debris in the wastewater will be transported to the second collection box 10 on the right side of the treatment tank 2 along with the filter belt 71. At the same time, the wool and debris adhering to the filter belt 71 are scraped off by the brush roller 81 on the scraping mechanism 8 at the left end of the filter belt 71 and fall into the first collection box 9.

[0066] Before entering the treatment tank 2, the wastewater leaking into the tank also needs to be filtered again through the fine pore filter screen provided on the rib 22 to filter out the fine particles in the wastewater. For the wastewater entering the treatment tank 2, a disinfectant needs to be added through the chemical agent inlet 21 and precipitated again. When the wastewater meets the standards, it is pumped out by the recovery water pump 11 for continued use.

[0067] The present invention filters large particle impurities, sand grains, wool debris, fine particle impurities, etc. in the wool washing wastewater of sheepskins one by one through the grading and stirring tank 4, the filtration and collection mechanism 7, and the treatment tank 2, enabling the wool washing wastewater of sheepskins to meet the reuse standards, thereby saving water resources. Moreover, the device is vertically designed, which is conducive to hierarchical treatment and reduces the occupied space. A partition and filtration mechanism 14 is arranged in the grading and stirring tank 4. By moving the second filter plate 142, the filter holes 143 on the first filter plate 141 and the second filter plate 142 can be misaligned, thereby partitioning the primary treatment chamber and the secondary treatment chamber, enabling the stirring mechanisms in the primary treatment chamber and the secondary treatment chamber to stir and process separately. After the primary treatment chamber is processed, the filter holes 143 can be overlapped and opened, allowing the wastewater after primary treatment to enter the secondary treatment chamber. At the same time, the size of the filter holes 143 can be adjusted according to the impurity situation in the wastewater after primary treatment to precisely filter the large particle impurities in the preliminarily treated wastewater and keep them in the primary treatment chamber, improving the filtration effect. The filtration and collection mechanism 7 can filter the wool debris remaining in the wastewater filtered by the grading and stirring tank 4 again, transport the wool debris to the collection box for collection, and at the same time, scrape off the wool debris adhering to the filter belt 71 through the scraping mechanism 8 to prevent it from adhering to the filter belt 71 and affecting the filtration effect of the filter belt 71. The two sides of the upper port of the treatment tank 2 extend outward, facilitating the wastewater to fall into the treatment tank 2 and filtering out fine particle impurities through the filter screen at the mouth of the treatment tank 2, increasing the filtration effect.
