[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0022] As Figures 1 to 6As shown in the figure, a textile wastewater harmless treatment device according to an embodiment of the present invention includes a treatment cylinder 1. A water inlet pipe 11 is connected and fixed to the top of the treatment cylinder 1. A filter basket 22 is fixedly connected to the inner wall of the top of the treatment cylinder 1. A cleaning mechanism is provided in the treatment cylinder 1. The cleaning mechanism includes a first motor 2 fixed to the top of the treatment cylinder 1. The output shaft of the first motor 2 is rotatably connected to the treatment cylinder 1 through a bearing. The output shaft of the first motor 2 is fixedly connected with a first rotating rod 21. A plurality of arc-shaped blades 214 are fixedly connected to the outer wall of the top end of the first rotating rod 21. The arc-shaped blades 214 are all in contact with the inner wall of the filter basket 22. A plurality of stirring paddles 212 are fixedly connected to the outer wall of the bottom end of the first rotating rod 21. Two adsorption covers 213 are rotatably connected to the outer wall of the first rotating rod 21 through bearings. The top of the adsorption cover 213 is flush with the bottom of the filter basket 22. A torsion spring is provided at the connection between the adsorption cover 213 and the first rotating rod 21. A limiting mechanism is provided at both ends of the adsorption cover 213. One end of the top of the adsorption cover 213 is connected and fixed with a telescopic pipe 24. The top of the telescopic pipe 24 penetrates and is connected to the treatment cylinder 1, and is connected and fixed with a conveying pipe 241. A collection box 243 and an adsorption pump 242 are fixed to the top of the treatment cylinder 1. One end of the conveying pipe 241 is installed on the adsorption pump 242, and the output end of the adsorption pump 242 is installed on the collection box 243. A pressure box is further provided on one side of the treatment cylinder 1.

[0023] With the vigorous development of the textile industry, while creating economic benefits, textile wastewater also has a greater impact on the environment. There are a large number of complex chemical substances in textile wastewater, and direct discharge will cause water pollution. Therefore, it is necessary to use a harmless treatment device to treat textile wastewater. However, due to the soft texture of cotton wool, it is very easy to drill into the holes of the filter plate 231. Large particles of cotton wool may block the filter plate 231, making the water flow unable to continue passing through. Small particles of cotton wool may flow with the water, resulting in poor filtering effect of the filter plate 231.

[0024] When the cleaning mechanism provided by the present invention is in use, textile wastewater enters the filter basket 22 through the water inlet pipe 11. Under the action of the filter basket 22, large particle cotton floc impurities are filtered. Some small particle impurities pass through the filter basket 22 and flow down with the water. During the process of inputting wastewater, by starting the first motor 2, the first motor 2 drives the first rotating rod 21 to rotate. The first rotating rod 21 drives the arc-shaped blade 214 to rotate, and the arc-shaped blade 214 scrapes the cotton flocs on the inner wall of the filter basket 22; the air is crushed into bubbles by the high-speed rotation of the stirring paddle 212. When there are more small particle cotton flocs in the wastewater, the treatment cylinder 1 can also be pressurized by the pressure box to dissolve air in the water, and then decompressed and released to form microbubbles. By generating tiny bubbles, the bubbles adhere to the suspended substances, oil stains or solid particles in the water to form a "bubble-particle" complex with a density less than that of water. After floating to the water surface, at this time, by releasing the fixation of the adsorption cover 213 of the limiting mechanism, the adsorption cover 213 rotates with the rotation of the first rotating rod 21. During the rotation process, the adsorption pump 242 is started, and the suspended substances, oil stains or solid particles adhered in the water are adsorbed by the adsorption cover 213, and then are respectively conveyed into the collection box 243 through the telescopic pipe 24 and the conveying pipe 241. When the adsorption cover 213 rotates 180 degrees, the first motor 2 is turned off, and the adsorption cover 213 quickly resets under the action of the torsion spring, and can be adsorbed several times reciprocally. Then the limiting mechanism is lowered to limit and fix the adsorption cover 213 again, so as to realize the all-round cleaning of the cotton flocs, prevent water pollution caused by cotton floc substances, and prevent cotton floc substances from affecting subsequent treatment.

[0025] As Figure 3 and Figure 5 As shown, the limiting mechanism includes two side plates 231 fixedly connected to the outer wall of the filter basket 22. Electric push rods 23 are fixedly connected to the tops of the side plates 231. The output ends of the electric push rods 23 are fixedly connected with limiting blocks 232, and the limiting blocks 232 are respectively in close fit with the straight wall surfaces of the adsorption cover 213.

[0026] When the limiting mechanism provided by the present invention is in use, when adsorption is not required, by starting the electric push rod 23, the electric push rod 23 drives the limiting blocks 232 to move downward. The limiting blocks 232 are respectively arranged on the two straight wall surfaces at the two ends of the adsorption cover 213, so as to lock the adsorption cover 213. When the first rotating rod 21 rotates, the adsorption cover 213 is blocked by resistance and cannot rotate; During adsorption, by releasing the fixation of the limiting block 232 on the adsorption cover 213, when the first rotating rod 21 starts to rotate, a relative angular difference will occur between the adsorption cover 213 and the torsion spring. The first rotating rod 21 causes the torsion spring to be twisted, and the torque generated by the torsion spring will act on the adsorption cover 213, forcing it to rotate with the first rotating rod 21 to reduce the angular difference. Eventually, the rotating plate will accelerate under the drive of the torsion spring torque and gradually approach the rotation speed of the rotating shaft. When the adsorption cover 213 rotates 180 degrees, the impurities floating in the processing cylinder 1 are cleaned up.

[0027] As Figure 4 shown, a chute 226 is provided in the filter basket 22, and a sealing plate 221 is slidably connected in the chute 226; a discharge bin 227 is fixedly connected to the outer wall of the processing cylinder 1, and a discharge port is provided on the filter basket 22, and the top side wall of the discharge bin 227 is connected and matched with the discharge port; an L-shaped plate 225 is fixedly connected to the top of the processing cylinder 1, a second motor 224 is fixedly connected to the bottom of the L-shaped plate 225, and a push rod 223 is fixedly connected to the output shaft of the second motor 224; a push block 222 is fixedly connected to the top of the sealing plate 221, and the push block 222 is sleeved in the push rod 223.

[0028] The sealing plate 221 provided by the present invention is used to seal the filter basket 22 during use. After a period of time, when there is a lot of cotton wool accumulated in the filter basket 22 and needs to be cleaned, by turning on the second motor 224, the output shaft of the second motor 224 drives the push rod 223 to rotate, drives the push block 222 to rotate through the push rod 223, drives the sealing plate 221 to rotate through the push block 222, and the sealing plate 221 releases the sealing of the discharge port. Then, during the rotation of the first rotating rod 21, the arc-shaped blade 214 is driven to rotate by the first rotating rod 21, and the centrifugal force generated when the arc-shaped blade 214 rotates throws the cotton wool out to the discharge bin 227, realizing the function of cleaning the cotton wool 386. Among them, the first motor 2 is a forward and reverse rotation motor.

[0029] As Figures 1 to 2 shown, a mixing cylinder 3 is provided on one side of the processing cylinder 1; the bottom end of the processing cylinder 1 is connected and fixedly connected with a connecting pipe 12, and the other end of the connecting pipe 12 is connected and fixedly connected to the top of the mixing cylinder 3; a water pump 13 is provided on the connecting pipe 12; a filter screen is fixedly connected to the connecting pipe 12 near the processing cylinder 1; a U-shaped scraper 211 is fixedly connected to the outer wall of the first rotating rod 21.

[0030] The mixing cylinder 3 provided by the present invention is used to neutralize and flocculate the pretreated wastewater during use to remove other impurities dissolved in the water. The wastewater in the processing cylinder 1 is transported to the mixing cylinder 3 through the connecting pipe 12 by the water pump 13. During the transportation process, the impurities scraped by the U-shaped scraper 211 and other impurities in the water are filtered under the action of the filter screen.

[0031] As Figure 2 and Figure 8 shown, two medicine storage tanks 33 are connected and fixedly attached to the top of the mixing cylinder 3. Driving motors 331 are fixedly attached to the tops of the medicine storage tanks 33. Output shafts of the driving motors 331 are rotatably connected to the medicine storage tanks 33 through bearings. Third rotating rods 332 are fixedly attached to the output shafts of the driving motors 331. Augers 333 are fixedly attached to the third rotating rods 332; electromagnetic valves 334 are installed at the bottom ends of the medicine storage tanks 33; a water level gauge 37 is fixedly attached to the inner wall of the top of the mixing cylinder 3.

[0032] When the medicine storage tank 33 provided by the present invention is in use, one is used to place a neutralizing agent and the other is used to place a flocculant. The neutralizing agent is first put into water for a neutralization reaction. When the appropriate pH value is reached, the flocculant is put in, which helps the flocculation sedimentation of the precipitate. In order to facilitate the dredging of the neutralizing agent and the flocculant, by starting the driving motor 331, the output shaft of the driving motor 331 drives the third rotating rod 332 to rotate. The third rotating rod 332 drives the auger 333 to rotate. When the auger 333 rotates, it squeezes and crushes large pieces of materials. The amounts of the placed neutralizing agent and flocculant are determined according to the water level gauge 37.

[0033] As Figure 2 shown, a third motor 32 is fixedly attached to the top of the treatment cylinder 1. The output shaft of the third motor 32 is rotatably connected to the treatment cylinder 1 through a bearing. A second rotating rod 321 is fixedly attached to the output shaft of the third motor 32. Stirring rods 322 are fixedly attached to the outer wall of the second rotating rod 321; an ash hopper 35 is connected and fixedly attached to the bottom of the treatment cylinder 1. A scraping rod 323 is fixedly attached to the outer wall of the second rotating rod 321. The scraping rod 323 is in contact with the inner wall of the bottom of the ash hopper 35; a temperature sensor 36 is installed on one of the stirring rods 322.

[0034] When the scraping rod 323 provided by the present invention is in use, it is used to scrape the impurities adhered to the inner wall of the ash hopper 35. By starting the third motor 32, the output shaft of the third motor 32 drives the second rotating rod 321 to rotate. The second rotating rod 321 drives the stirring rod 322 to rotate for mixing the neutralizing agent. The rotation speed is faster when the neutralizing agent is put in and slower when the flocculant is put in. The second rotating rod 321 drives the scraping rod 323 to rotate. During the rotation of the scraping rod 323, it is convenient to clean the inner wall of the ash hopper 35.

[0035] As Figure 9As shown, a mounting frame 381 is fixedly connected to the top of the mixing cylinder 3. A fourth motor 382 is fixedly connected to the top of the mounting frame 381. The output shaft of the fourth motor 382 is rotatably connected to the mounting frame 381 through a bearing. A reciprocating lead screw 384 is fixedly connected to the output shaft of the fourth motor 382. A lifting plate 387 is threadedly connected to the reciprocating lead screw 384. A pH meter 38 is fixedly connected to the lifting plate 387. Two vertical rods 383 are fixedly connected between the mounting frame 381 and the mixing cylinder 3. The lifting plate 387 is slidably connected to the two vertical rods 383. A fixing sleeve 385 is installed on the inner wall of the top of the mixing cylinder 3. A cleaning cotton 386 is fixedly connected inside the fixing sleeve 385. The pH meter 38 penetrates through the mixing cylinder 3 and is sleeved inside the cleaning cotton 386.

[0036] The pH meter 38 provided by the present invention is used to monitor the pH value of wastewater during use. After the pH meter 38 is used for a period of time, impurities in the water will adhere to its surface, affecting the accuracy of its detection. By turning on the fourth motor 382, the fourth motor 382 drives the reciprocating lead screw 384 to rotate through the output shaft. The reciprocating lead screw 384 drives the lifting plate 387 to move up and down reciprocally. The lifting plate 387 drives the pH meter 38 to move up and down reciprocally. During the movement of the pH meter 38, it rubs against the cleaning cotton 386, and the cleaning cotton 386 cleans the impurities on the surface.

[0037] As Figure 2 and Figure 7 As shown, a jacket 31 is fixedly connected to the outer wall of the mixing cylinder 3. A cooling pipe 314 is installed inside the jacket 31. A fixing plate 311 is fixedly connected to the outer wall of the jacket 31. A cooling tank 312 and a circulation pump 313 are fixedly connected to the top of the fixing plate 311. The circulation pump 313 and the cooling tank 312 are connected by a hose. The input end of the cooling pipe 314 is fixedly connected in communication with a liquid inlet pipe 315. The output end of the cooling pipe 314 is fixedly connected in communication with a liquid discharge pipe 316. One ends of the liquid inlet pipe 315 and the liquid discharge pipe 316 are respectively connected to the circulation pump 313. The circulation pump 313 is electrically connected to a temperature sensor 36. A heating sleeve 34 is fixedly connected to the outer wall of the ash hopper 35. A plurality of heating wires are fixedly connected to the inner wall of the heating sleeve 34. The heating wires are electrically connected to the temperature sensor 36.

[0038] The heating wire and the cooling pipe 314 provided by the present invention are respectively used for heating and cooling the wastewater in the mixing cylinder 3 during use. According to the temperature monitored by the temperature sensor 36 in the water, if the temperature is lower than the set value, the temperature sensor 36 transmits a signal to the system, and the system controls the heating wire to heat up and increase the temperature. Heating can accelerate the reaction rate. Especially when the precipitate is colloidal or flocculent, the gaps between the initial precipitates will hinder the contact of reactants. By heating, the unreacted substances continue to react until complete precipitation. However, when the temperature is higher than the set value, the temperature sensor 36 will transmit a signal to the system, and the system controls the circulation pump 313 and the refrigerator to cool. Cooling is usually used in the solid-liquid separation stage after precipitation. If the temperature is too high, the formed precipitate may redissolve. By cooling, the aggregation of colloidal particles can be accelerated, and the filtration efficiency can be improved.

[0039] As Figure 2 shown, a solid-liquid separator 352 is installed at the bottom of the ash hopper 35. A sewage discharge pipe 353 is connected and fixed to the bottom of the solid-liquid separator 352; a drain pipe 354 is connected and fixed to the side wall of the solid-liquid separator 352; a discharge valve 351 is installed at the bottom of the ash hopper 35.

[0040] The solid-liquid separator 352 provided by the present invention separates the discharged precipitate and water during use. The precipitate is discharged through the sewage discharge pipe 353, and the treated water is discharged through the drain pipe 354.

[0041] Working principle: Textile wastewater enters the filter basket 22 through the water inlet pipe 11. Under the action of the filter basket 22, large particle cotton floc impurities are filtered. Some small particle impurities pass through the filter basket 22 and flow down with the water. During the input of wastewater, by starting the first motor 2, the first motor 2 drives the first rotating rod 21 to rotate. The first rotating rod 21 drives the arc-shaped blade 214 to rotate, and the arc-shaped blade 214 scrapes the cotton flocs on the inner wall of the filter basket 22; the air is crushed into bubbles by the high-speed rotation of the stirring paddle 212. When there are more small particle cotton flocs in the wastewater, the treatment cylinder 1 can also be pressurized by the pressure box to dissolve air in the water, and then decompressed and released to form micro-bubbles. By generating tiny bubbles, the bubbles adhere to the suspended solids, oil or solid particles in the water to form a "bubble-particle" complex with a density less than that of water. After floating to the water surface, at this time, by releasing the fixation of the adsorption cover 213 of the limit mechanism, the adsorption cover 213 rotates with the rotation of the first rotating rod 21. During the rotation process, the adsorption pump 242 is started, and the suspended solids, oil or solid particles adhered in the water are adsorbed by the adsorption cover 213, and then are respectively conveyed into the collection box 243 through the telescopic pipe 24 and the conveying pipe 241. When the adsorption cover 213 rotates 180 degrees, the first motor 2 is turned off, and the adsorption cover 213 quickly resets under the action of the torsion spring, and can be adsorbed several times reciprocally. Then the limit mechanism is lowered to limit and fix the adsorption cover 213 again, so as to realize the all-round cleaning of cotton flocs, prevent water pollution caused by cotton floc substances, and prevent cotton floc substances from affecting subsequent treatment.

[0042] When adsorption is not required, by starting the electric push rod 23, the electric push rod 23 drives the limit block 232 to move downward. The limit blocks 232 are respectively arranged on the two straight side walls of the adsorption cover 213, so as to lock the adsorption cover 213. When the first rotating rod 21 rotates, the adsorption cover 213 is unable to rotate due to the resistance. During adsorption, by releasing the fixation of the limit block 232 on the adsorption cover 213, when the first rotating rod 21 starts to rotate, there will be a relative angle difference between the adsorption cover 213 and the torsion spring. The first rotating rod 21 causes the torsion spring to be twisted, and the torque generated by the torsion spring acts on the adsorption cover 213, forcing it to rotate with the first rotating rod 21 to reduce the angle difference. Finally, the rotating plate will accelerate under the drive of the torsion spring torque and gradually approach the rotation speed of the rotating shaft. When the adsorption cover 213 rotates 180 degrees, the impurities floating in the treatment cylinder 1 are cleaned up.

[0043] After a period of time, when there is a large amount of cotton wadding accumulated in the filtering basket 22 and it needs to be cleaned, the second motor 224 is turned on. The output shaft of the second motor 224 drives the push rod 223 to rotate. The push rod 223 drives the push block 222 to rotate. The push block 222 drives the sealing plate 221 to rotate. The sealing plate 221 releases the blockage of the discharge port. Then, during the rotation of the first rotating rod 21, the first rotating rod 21 drives the arc-shaped blade 214 to rotate. The centrifugal force generated when the arc-shaped blade 214 rotates throws the cotton wadding out to the material discharging bin 227, realizing the function of cleaning the cotton wadding. The first motor 2 is a forward and reverse rotation motor.

[0044] The wastewater in the treatment cylinder 1 is transported to the mixing cylinder 3 through the water pump 13 via the connecting pipe 12. During the transportation process, the impurities scraped by the U-shaped scraper 211 and other impurities in the water are filtered under the action of the filter screen. One of the medicine storage tanks 33 is used to place the neutralizing agent, and the other medicine storage tank 33 is used to place the flocculant. The neutralizing agent is first put into the water for neutralization reaction. When the appropriate pH value is reached, the flocculant is then put in, which helps the flocculation sedimentation of the precipitate. To facilitate the dredging of the neutralizing agent and the flocculant, the driving motor 331 is turned on. The output shaft of the driving motor 331 drives the third rotating rod 332 to rotate. The third rotating rod 332 drives the auger 333 to rotate. When the auger 333 rotates, it squeezes and crushes large pieces of materials. The amount of the neutralizing agent and the flocculant placed is determined according to the water level gauge 37.

[0045] After the pH meter 38 is used for a period of time, there will be impurities in the water adhering to its surface, affecting the accuracy of its detection. By turning on the fourth motor 382, the fourth motor 382 drives the reciprocating lead screw 384 to rotate through the output shaft. The reciprocating lead screw 384 drives the lifting plate 387 to move up and down reciprocally. The lifting plate 387 drives the pH meter 38 to move up and down reciprocally. During the movement of the pH meter 38, it rubs against the cleaning cotton 386, and the cleaning cotton 386 cleans the impurities on the surface.

[0046] The heating wire and the cooling pipe 314 are respectively used for heating and cooling the wastewater in the mixing cylinder 3 during use. According to the temperature of the water monitored by the temperature sensor 36, if the temperature is lower than the set value, the temperature sensor 36 transmits the signal to the system, and the system controls the heating wire to heat up and raise the temperature. Heating can accelerate the reaction rate. Especially when the precipitate is colloidal or flocculent, the gaps between the initial precipitates will hinder the contact of the reactants. By heating, the unreacted substances continue to react until complete precipitation. However, when the temperature is higher than the set value, the temperature sensor 36 will transmit the signal to the system, and the system controls the circulation pump 313 and the refrigerator to cool down. Cooling is usually used in the solid-liquid separation stage after precipitation. If the temperature is too high, the formed precipitate may redissolve. By cooling, the aggregation of colloidal particles can be accelerated, and the filtration efficiency can be improved.

[0047] Finally, the discharged sediment and water are separated by the solid-liquid separator 352. The sediment is discharged through the sewage pipe 353, and the treated water is discharged through the drain pipe 354.
