[0026] The second electric push rod 210 is started to drive the fitting ring 401 to rise to the specified position, and then the second motor 208 is started to drive the second fixed disk 209 to rotate. The second fixed disk 209 rotates and drives the several groups of sealing covers 305 on the vacuum cylinder 213 to rotate until they are located directly above the several groups of water buckets 405. Then the second electric push rod 210 is started to drive the water buckets 405 to rise and engage with the sealing covers 305.

[0027] Start the air pump 302 to suck the evaporated wastewater gas into the vacuum cylinder 213, and first filter the waste gas through the filter cylinder 303. After entering the vacuum cylinder 213, the temperature inside the vacuum cylinder 213 will rise, and the untreated wastewater in the waste liquid tank 1 will begin to be heated, thereby improving the auxiliary effect of subsequent heating. The high-temperature waste gas will begin to liquefy when it contacts the inner wall of the vacuum cylinder 213. The liquefied wastewater can be input into the waste liquid tank 1 by opening the first electric ball valve 214 for wastewater dilution, thereby improving the water source reuse effect while improving the auxiliary effect of the device.

[0028] For example, Figure 5 , Figure 6 and Figure 7As shown, the recovery component 3 includes a first connecting pipe 301, and a group of air pumps 302 are installed on the outer wall of each group of the first connecting pipes 301, one end of each group of the first connecting pipes 301 is connected to a group of filter cartridges 303, the outer wall of each group of the filter cartridges 303 is connected to one end of a group of second connecting pipes 304, the other end of each group of the second connecting pipes 304 is connected to the outer wall of the vacuum cylinder 213, the other end of each group of the first connecting pipes 301 is connected to a group of sealing covers 305, the top of each group of the sealing covers 305 is connected to a group of input pipes 306, the outer wall of each group of the injection pipes 206 is slidably connected to the inner wall of the input pipe 306, and a group of third electric push rods 30 are installed on the inner wall of the top of each group of the sealing covers 305. 7. An auxiliary cylinder 308 is installed on the output end of each group of the third electric push rods 307, a second electric ball valve 309 is installed on the bottom of each group of the auxiliary cylinder 308, a fourth electric push rod 310 is installed on the top inner wall of each group of the auxiliary cylinder 308, a bonding plate 311 is installed on the output end of each group of the fourth electric push rods 310, the outer wall of each group of the bonding plate 311 is slidably connected to the inner wall of the auxiliary cylinder 308, a plurality of second electric slides 312 are distributed in a circular array on the inner wall of each group of the sealing cover 305, a third motor 313 is transmission-connected to the output end of each group of the second electric slides 312, and a stirring rod 314 is transmission-connected to the output end of each group of the third motor 313.

[0029] The first electric slide 205 is started to drive the injection tube 206 to move to the top of the input tube 306, and the input tube 306 is sealed. The heating box 207 then transports hot air into the injection tube 206. The hot air in the injection tube 206 enters the water bucket 405 through the input tube 306 to evaporate the wastewater. Since the boiling point of the wastewater is different from that of cellulose, the cellulose will not be affected after the water evaporates. During the evaporation process, the second electric slide 312 is started to cooperate with the third motor 313 to drive the stirring rod 314 to perform translational stirring on the wastewater, which speeds up the evaporation process and makes the cellulose more active, thereby improving the environmentally friendly recovery effect of cellulose in textile waste liquid.

[0030] After the water evaporates, the cellulose gathers in the water bucket 405 and the vacuum tube 402. The third electric push rod 307 is started to drive the auxiliary cylinder 308 to descend to the specified position, and then the fourth electric push rod 310 is started to drive the bonding plate 311 to rise, so that the auxiliary cylinder 308 is in a negative pressure state, and the cellulose is sucked into the auxiliary cylinder 308 for storage, thereby improving the storage effect and sealing effect of the device.

[0031] For example, Figure 8As shown, the diversion component 4 includes a fitting ring 401, which is movably sleeved on the outer wall of the vacuum cylinder 213, and the top of the fitting ring 401 is installed on the bottom of the transmission tube 212.

When the waste water enters the water bucket 405, it drives cellulose to enter synchronously, and then the third electric ball valve 403 is closed to allow the waste water to accumulate in the water bucket 405, thereby improving the impurity removal effect and the waste water stratification collection effect.

[0033] The first electric slide 205 is started to drive the injection tube 206 to move to the top of the input tube 306, and the input tube 306 is sealed. The heating box 207 then transports hot air into the injection tube 206. The hot air in the injection tube 206 enters the water bucket 405 through the input tube 306 to evaporate the wastewater. Since the boiling point of the wastewater is different from that of cellulose, the cellulose will not be affected after the water evaporates. During the evaporation process, the second electric slide 312 is started to cooperate with the third motor 313 to drive the stirring rod 314 to perform translational stirring on the wastewater, which speeds up the evaporation process and makes the cellulose more active, thereby improving the environmentally friendly recovery effect of cellulose in textile waste liquid.

[0034] The waste water is input into the waste liquid tank 1, and then the first electric push rod 202 is started to drive the vacuum cylinder 213 into the waste water, and then the second electric push rod 210 is started to drive the transmission tube 212 to descend. While the transmission tube 212 descends, it drives several groups of vacuum tubes 402 to penetrate into the waste water, and then several groups of third electric ball valves 403 are opened to allow the waste water to enter the water bucket 405, and impurities are removed through the gauze pad 404 during the waste water entering process. When the waste water enters the water bucket 405, it drives cellulose to enter synchronously, and then the third electric ball valve 403 is closed to allow the waste water to accumulate in the water bucket 405, thereby improving the impurity removal effect and the waste water stratification collection effect.

[0035] Start the air pump 302 to suck the evaporated wastewater gas into the vacuum cylinder 213, and first filter the waste gas through the filter cylinder 303. After entering the vacuum cylinder 213, the temperature inside the vacuum cylinder 213 will rise, and the untreated wastewater in the waste liquid tank 1 will begin to be heated, thereby improving the auxiliary effect of subsequent heating. The high-temperature waste gas will begin to liquefy when it contacts the inner wall of the vacuum cylinder 213. The liquefied wastewater can be input into the waste liquid tank 1 by opening the first electric ball valve 214 for wastewater dilution, thereby improving the water source reuse effect while improving the auxiliary effect of the device.

[0036] The plurality of sealing covers 305 on the vacuum cylinder 213 are driven to rotate until they are located directly above the plurality of water buckets 405, and then the second electric push rod 210 is started to drive the water buckets 405 to rise and engage with the sealing covers 305; after the water evaporates, the cellulose is gathered in the water buckets 405 and the vacuum tube 402, and the third electric push rod 307 is started to drive the auxiliary cylinder 308 to descend to the specified position, and then the fourth electric push rod 310 is started to drive the bonding plate 311 to rise, so that the auxiliary cylinder 308 is in a negative pressure state, and the cellulose is sucked into the auxiliary cylinder 308 for storage, thereby improving the storage effect and sealing effect of the device.
