[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1-8 As shown, a multi-stage filtration wastewater recovery device for chemical fiber fabric production according to an embodiment of the present utility model includes a treatment cylinder 1, a first treatment component 2 is provided at the upper end of the treatment cylinder 1, and a controller 4 is provided on one side of the treatment cylinder 1.

[0029] The first processing component 2 includes a water inlet pipe 201, one end of which is connected to the upper end of the processing cylinder 1 and extends into the interior of the processing cylinder 1. A filter cylinder 202 is connected to the other end of the water inlet pipe 201. A first motor 203 is bolted to the upper end of the processing cylinder 1. A rotating rod 204 is mounted on the output shaft of the first motor 203 via a coupling. One end of the rotating rod 204 extends into the interior of the processing cylinder 1. A stirring blade 205 is mounted on the end of the rotating rod 204 located inside the processing cylinder 1. A stirring blade 205 is mounted directly below the rotating rod 204. A guide cover 206 is provided and fixedly installed on the inner wall of the processing cylinder 1. A control valve 5 is provided at one end of the guide cover 206. A storage tank 207 is provided on one side of the processing cylinder 1. A first pump body 208 is connected to one side of the storage tank 207 and is installed on one side of the processing cylinder 1 through a fixed seat. The output end of the first pump body 208 is connected to a conveying pipe 209. One end of the conveying pipe 209 extends into the interior of the processing cylinder 1. Multiple output nozzles 210 are provided at the end of the conveying pipe 209 located inside the processing cylinder 1.

[0030] In practical applications, wastewater generated during the production of chemical fiber fabrics enters the treatment cylinder 1 through the inlet pipe 201. The wastewater first undergoes preliminary filtration through the filter cylinder 202 to remove larger suspended solids and particulate impurities, such as fiber debris. After the preliminary filtration, the wastewater flows into the treatment cylinder 1, and the first motor 203 starts, driving the rotating rod 204 and the stirring blades 205 fixed thereon to rotate. This process not only helps to further disperse the fine particles in the wastewater, but also promotes the thorough mixing of the wastewater with any added chemical agents (such as flocculant solutions). The chemical agents or other additives in the storage tank 207 can be quantitatively extracted and transported into the treatment cylinder 1 through the first pump body 208 and the delivery pipe 209. These additives are evenly distributed into the wastewater through multiple output nozzles 210, further enhancing the treatment effect and facilitating subsequent sedimentation or separation operations. During the stirring process, the wastewater is guided by the guide hood 206 to ensure a more uniform water flow distribution and ultimately flows towards the control valve 5. The guide hood 206 helps to optimize the water flow path and improve treatment efficiency.

[0031] Example 2:

[0032] like Figures 1-8 As shown, a multi-stage filtration wastewater recovery device for chemical fiber fabric production according to an embodiment of the present utility model includes a treatment cylinder 1, a second treatment component 3 is provided at the bottom end of the treatment cylinder 1, and a controller 4 is provided on one side of the treatment cylinder 1.

[0033] The second processing component 3 includes a second motor 301, which is bolted to the bottom of the processing cylinder 1. The output shaft of the second motor 301 extends into the interior of the processing cylinder 1, where a centrifugal separation cylinder 302 is located. One end of the centrifugal separation cylinder 302 is mounted on the inner wall of the processing cylinder 1 via a bearing. An output pipe 303 is connected to the bottom of the processing cylinder 1, and one end of the output pipe 303 is connected to a second filter cylinder 304. The second filter cylinder 304 is a multi-layer composite filter element (typically containing a 20-50μm precision stainless steel filter screen + activated carbon layer). One end of the second filter cylinder 304 is connected to a second pump body 305, which is mounted on one side of the processing cylinder 1 via a fixing seat. The output end of the second pump body 305 is connected to a connecting pipe 306, and one end of the connecting pipe 306 is equipped with a detection cylinder 307, on which is embedded... A detector 308 is provided, which is a conventional water quality detector (usually composed of a pH sensor, a turbidity meter, and a COD detection module). One end of the detection cylinder 307 is connected to a diversion pipe 309, one end of which is connected to the treatment cylinder 1. In actual use, the other end of the diversion pipe 309 is connected to an external recovery container. A control valve 6 is provided on the diversion pipe 309. A third pump body 310 is provided on one side of the treatment cylinder 1 via a fixed base 3. The input end of the third pump body 310 is connected to a filter box 311, and the filter box 311 is fixedly installed on one side of the treatment cylinder 1. One end of the filter box 311 is connected to a collection pipe 312, one end of which penetrates the treatment cylinder 1 and is located inside the centrifugal separation cylinder 302. Multiple collection covers 313 are provided on the collection pipe 312.

[0034] In practical applications, after the wastewater is stirred with added chemical agents, it enters the centrifugal separator 302. The second motor 301 drives the centrifugal separator 302 to rotate at high speed, achieving initial solid-liquid separation through centrifugal force. The denser suspended particles are thrown against the cylinder wall, and the centrifuged liquid enters the filter cylinder 304 through the bottom output pipe 303 for deep filtration to remove fine particles and organic pollutants. Then, the second pump 305 pumps the filtrate into the detection cylinder 307. The detector 308 monitors the water quality parameters in real time. When the detection value is qualified, the controller 4 opens the recovery channel through the control valve 6, and the purified water enters the reuse system through the diversion pipe 309. If the detection exceeds the standard, the control valve 6 is switched to return the liquid to the treatment cylinder 1 for recirculation. The number of cycles can reach three to five. The collection hood 313 uses negative pressure adsorption, and then the centrifuged sludge is transported to the filter box 311 through the collection pipe 312, thus avoiding subsequent manual cleaning.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In summary, with the help of the above-mentioned technical solution of this utility model, the wastewater generated in the production process of chemical fiber fabric enters the treatment cylinder 1 through the inlet pipe 201. The wastewater first undergoes preliminary filtration through the filter cylinder 202 to remove larger suspended solids and particulate impurities, such as fiber debris. After the wastewater undergoes preliminary filtration, it flows into the treatment cylinder 1, and the first motor 203 starts, driving the rotating rod 204 and the stirring blade 205 fixed thereon to rotate. This process not only helps to further disperse fine particles in the wastewater, but also promotes thorough mixing of the wastewater with any added chemicals (such as flocculant solutions). The chemicals or other additives in the storage tank 207 can be quantitatively extracted and transported to the treatment cylinder 1 via the first pump body 208 and the delivery pipe 209. These additives are evenly distributed into the wastewater through multiple output nozzles 210, further enhancing the treatment effect and facilitating subsequent sedimentation or separation operations. During the mixing process, the wastewater is guided by the guide hood 206 to ensure a more uniform water flow distribution, ultimately flowing towards the control valve 5. The guide hood 206 helps optimize the water flow path and improve treatment efficiency. After the chemical mixing is completed, the wastewater enters the centrifugal separation cylinder 302, driven by the second motor 301. Centrifugal separator 302 rotates at high speed, achieving initial solid-liquid separation through centrifugal force. The denser suspended particles are thrown against the cylinder wall. The centrifuged liquid enters filter cylinder 304 through bottom output pipe 303 for deep filtration, removing fine particles and organic pollutants. Then, the second pump 305 pumps the filtrate into the detection cylinder 307. The detector 308 monitors water quality parameters in real time. When the detection value is qualified, the controller 4 opens the recovery channel of control valve 6, and the purified water enters the reuse system through the diversion pipe 309. If the detection exceeds the standard, the control valve 6 is switched to return the liquid to the treatment cylinder 1 for recirculation. The number of cycles can reach three to five.
