DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 6As shown, a harmless treatment device for textile wastewater according to an embodiment of the present invention includes a treatment barrel 1, the top of the treatment barrel 1 is connected and fixedly connected to a water inlet pipe 11; a filter basket 22 is fixedly connected to the top inner wall of the treatment barrel 1; a cleaning mechanism is provided in the treatment barrel 1; the cleaning mechanism includes a first motor 2 fixedly connected to the top of the treatment barrel 1, the output shaft of the first motor 2 is rotatably connected to the treatment barrel 1 through a bearing, the output shaft of the first motor 2 is fixedly connected to a first rotating rod 21, a plurality of arc-shaped blades 214 are fixedly connected to the top outer wall of the first rotating rod 21, and 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 bottom outer wall of the first rotating rod 21; Two adsorption covers 213 are rotatably connected to the outer wall of the 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; both ends of the adsorption cover 213 are provided with a limiting mechanism; one end of the top of the adsorption cover 213 is connected and fixedly connected to a telescopic tube 24, the top of the telescopic tube 24 is connected to the treatment cylinder 1, and is connected and fixedly connected to a delivery pipe 241; the top of the treatment cylinder 1 is fixedly connected to a collection box 243 and an adsorption pump 242; one end of the delivery 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 also provided on one side of the treatment cylinder 1.

[0034] With the vigorous development of the textile industry, while creating economic benefits, textile wastewater has also brought great impacts on the environment. Textile wastewater contains a large amount of complex chemical substances, and direct discharge will cause water pollution. Therefore, it is necessary to use harmless treatment equipment to treat textile wastewater; however, due to the soft texture of cotton wool, it is easy to drill into the holes of the filter plate 231. Large particles of cotton wool may block the filter plate 231, making it impossible for water to continue to pass through, and small particles of cotton wool may flow with the water, resulting in poor filtering effect of the filter plate 231.

[0035] 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, and large particles of cotton wool impurities are filtered under the action of the filter basket 22, and some small particles of impurities pass through the filter basket 22 and flow down with the water. During the wastewater input process, the first motor 2 is turned on, and the first motor 2 drives the first rotating rod 21 to rotate, and the first rotating rod 21 drives the arc-shaped blades 214 to rotate, and the arc-shaped blades 214 scrape the cotton wool 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. If there are many small particles of cotton wool in the wastewater, the processing cylinder 1 can also be pressurized by the pressure box to dissolve the air in the water, and then the pressure is reduced to release it to form microbubbles. By generating tiny bubbles, the bubbles are mixed with suspended matter, oil or solid matter in the water. The air bubbles and the particles adhere to the adsorption cover 213 to form a "bubble-particle" complex with a density less than that of water. After floating to the water surface, the adsorption cover 213 of the limiting mechanism is released, and the adsorption cover 213 rotates with the rotation of the first rotating rod 21. During the rotation, the adsorption pump 242 is turned on, and the suspended matter, oil or solid particles in the water adhere to the adsorption cover 213 and are adsorbed, and then transported to the collection box 243 through the telescopic tube 24 and the conveying tube 241 respectively. When the adsorption cover 213 rotates 180 degrees, the first motor 2 is turned off, and the adsorption cover 213 is quickly reset under the action of the torsion spring, and can be adsorbed back and forth several times. Then the limiting mechanism is lowered and the adsorption cover 213 is limited and fixed again, so that the cotton wool can be cleaned in all directions, and the water pollution caused by the cotton wool can be prevented, and the cotton wool can be prevented from affecting the subsequent treatment.

[0036] like Figure 3 and Figure 5 As shown, the limiting mechanism includes two side plates 231 fixed to the outer wall of the filter basket 22, the top of each side plate 231 is fixed with an electric push rod 23, the output end of each electric push rod 23 is fixed with a limiting block 232, and the limiting blocks 232 are tightly fitted with the straight wall of the adsorption cover 213 respectively.

[0037] When the limiting mechanism provided by the present invention is in use and adsorption is not required, the electric push rod 23 is turned on, and the limiting blocks 232 are driven downward by the electric push rod 23. The limiting blocks 232 are respectively provided on the opposite ends of the adsorption cover 213, thereby locking the adsorption cover 213. When the first rotating rod 21 rotates, the adsorption cover 213 is unable to rotate due to resistance.

[0038] During adsorption, by releasing the fixation of the adsorption cover 213 by the limit block 232, when the first rotating rod 21 starts to rotate, a relative angle difference will appear 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 angle difference. Finally, the rotating plate will accelerate under the drive of the torsion spring torque, gradually approaching the rotation speed of the shaft, and when the adsorption cover 213 rotates 180 degrees, the impurities floating in the treatment cylinder 1 are cleaned.

[0039] like Figure 4 As shown, a slide groove 226 is provided in the filter basket 22, and a sealing plate 221 is slidably connected in the slide groove 226; a discharge bin 227 is fixedly connected to the outer wall of the treatment 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 cooperated with the discharge port; an L-shaped plate 225 is fixedly connected to the top of the treatment cylinder 1, and 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.

[0040] The sealing plate 221 provided by the present invention is used to seal the filter basket 22 when in use. After a period of time, a lot of cotton wool accumulates in the filter basket 22. When it needs to be cleaned, the second motor 224 is turned on, and the output shaft of the second motor 224 drives the push rod 223 to rotate, and the push block 222 is driven to rotate by the push rod 223, and the sealing plate 221 is driven to rotate by the push block 222. The sealing plate 221 releases the blockage of the discharge port, and then the first rotating rod 21 drives the arc blade 214 to rotate during the rotation process. The centrifugal force generated by the arc blade 214 during rotation throws the cotton wool into the discharge bin 227, thereby realizing the function of cleaning the cotton wool, wherein the first motor 2 is a forward and reverse motor.

[0041] like Figures 1 to 2 As shown, a mixing cylinder 3 is provided on one side of the treatment cylinder 1; the bottom end of the treatment 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 end of the connecting pipe 12 close to the treatment cylinder 1; a U-shaped scraper 211 is fixedly connected to the outer wall of the first rotating rod 21.

[0042] The mixing drum 3 provided by the present invention is used to neutralize and flocculate the pretreated wastewater when in use, and remove other impurities fused in the water. The wastewater in the treatment drum 1 is transported to the mixing drum 3 through the connecting pipe 12 by the water pump 13. During the transportation process, the impurities scraped off by the U-shaped scraper 211 and other impurities in the water are filtered under the action of the filter net.

[0043] like Figure 2 and Figure 8 As shown, the top of the mixing cylinder 3 is connected and fixedly connected to two medicine storage boxes 33, the tops of the medicine storage boxes 33 are fixedly connected to drive motors 331, the output shafts of the drive motors 331 are rotatably connected to the medicine storage boxes 33 through bearings, the output shafts of the drive motors 331 are fixedly connected to third rotating rods 332, and the third rotating rods 332 are fixedly connected to auger 333; the bottom ends of the medicine storage boxes 33 are installed with solenoid valves 334; a water level gauge 37 is fixedly connected to the top inner wall of the mixing cylinder 3.

[0044] When the medicine storage box 33 provided by the present invention is in use, one of them is used to place a neutralizer and the other is used to place a flocculant. The neutralizer is first added to the water for a neutralization reaction. After reaching a suitable pH value, the flocculant is added to help the flocculation and sedimentation of the precipitate. In order to facilitate the unblocking of the neutralizer and flocculant, the drive motor 331 is turned on, and the output shaft of the drive motor 331 drives the third rotating rod 332 to rotate, and the third rotating rod 332 drives the auger 333 to rotate. When the auger 333 rotates, it squeezes and crushes large pieces of material, and the amount of the placed neutralizer and flocculant is determined according to the water level meter 37.

[0045] like Figure 2 As shown, a third motor 32 is fixedly connected to the top of the treatment cylinder 1, and the output shaft of the third motor 32 is rotatably connected to the treatment cylinder 1 through a bearing, and the output shaft of the third motor 32 is fixedly connected to a second rotating rod 321, and a stirring rod 322 is fixedly connected to the outer wall of the second rotating rod 321; the bottom of the treatment cylinder 1 is connected and fixedly connected to an ash hopper 35, and a scraping rod 323 is fixedly connected to the outer wall of the second rotating rod 321, and the scraping rod 323 is in contact with the bottom inner wall of the ash hopper 35; a temperature sensor 36 is installed on one of the stirring rods 322.

[0046] When in use, the scraper rod 323 provided by the present invention is used to scrape off impurities adhered to the inner wall of the ash hopper 35. By turning on the third motor 32, the second rotating rod 321 is driven to rotate by the output shaft of the third motor 32, and the stirring rod 322 is driven to rotate by the second rotating rod 321 to stir the neutralizer mixture. The rotation speed is faster when the neutralizer is added, and the rotation speed is slower when the flocculant is added. The scraper rod 323 is driven to rotate by the second rotating rod 321. During the rotation of the scraper rod 323, it is convenient to clean the inner wall of the ash hopper 35.

[0047] like Figure 9As shown, a mounting bracket 381 is fixed to the top of the mixing drum 3, a fourth motor 382 is fixed to the top of the mounting bracket 381, an output shaft of the fourth motor 382 is rotatably connected to the mounting bracket 381 through a bearing, and the output shaft of the fourth motor 382 is fixed to a reciprocating screw 384, a lifting plate 387 is threadedly connected to the reciprocating screw 384, and a pH meter 38 is fixed to the lifting plate 387; two vertical rods 383 are fixed between the mounting bracket 381 and the mixing drum 3, and the lifting plate 387 is slidably connected to the two vertical rods 383; a fixing sleeve 385 is installed on the top inner wall of the mixing drum 3, and a cleaning cotton 386 is fixed in the fixing sleeve 385; the pH meter 38 passes through the mixing drum 3 and is sleeved in the cleaning cotton 386.

[0048] The pH meter 38 provided by the present invention is used to monitor the pH value of wastewater when in use. After the pH meter 38 has been used for a period of time, impurities in the water will adhere to the surface, affecting the accuracy of its detection. By turning on the fourth motor 382, ​​the fourth motor 382 drives the reciprocating screw 384 to rotate through the output shaft, and the reciprocating screw 384 drives the lifting plate 387 to reciprocate up and down, and the lifting plate 387 drives the pH meter 38 to reciprocate up and down. During the movement, the pH meter 38 rubs against the cleaning cotton 386, and the cleaning cotton 386 cleans the impurities on the surface.

[0049] like Figure 2 and Figure 7 As shown, a jacket 31 is fixedly connected to the outer wall of the mixing barrel 3, and a cooling pipe 314 is installed in the jacket 31; a fixing plate 311 is fixedly connected to the outer wall of the jacket 31, and a cooling box 312 and a circulating pump 313 are fixedly connected to the top of the fixing plate 311; the circulating pump 313 is connected to the cooling box 312 through a hose; the input end of the cooling pipe 314 is connected to a liquid inlet pipe 315, and the output end of the cooling pipe 314 is connected to a liquid discharge pipe 316; one end of the liquid inlet pipe 315 and the liquid discharge pipe 316 are respectively connected to the circulating pump 313; the circulating pump 313 is electrically connected to the temperature sensor 36; the outer wall of the ash hopper 35 is fixedly connected to a heating sleeve 34, and a plurality of heating wires are fixedly connected to the inner wall of the heating sleeve 34, and the heating wires are electrically connected to the temperature sensor 36.

[0050] The heating wire and cooling tube 314 provided by the present invention are used to heat and cool the wastewater in the mixing drum 3 respectively when in use. The temperature in the water is monitored by the temperature sensor 36. 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 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 the reactants, and heating will allow the unreacted substances to continue to react until they are completely precipitated; but when the temperature is higher than the set value, the temperature sensor 36 will transmit a signal to the system, and the system will control 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 generated precipitate may be redissolved. Cooling can accelerate the coagulation of colloidal particles and improve the filtration efficiency.

[0051] like Figure 2 As shown, a solid-liquid separator 352 is installed at the bottom of the ash hopper 35, and the bottom of the solid-liquid separator 352 is connected and fixedly connected to a sewage pipe 353; a drainage pipe 354 is connected and fixedly connected to the side wall of the solid-liquid separator 352; and a discharge valve 351 is installed at the bottom of the ash hopper 35.

[0052] The solid-liquid separator 352 provided by the present invention separates the discharged sediment and water when in use, the sediment is discharged through the sewage pipe 353, and the treated water is discharged through the drainage pipe 354.

[0053] Working principle: Textile wastewater enters the filter basket 22 through the water inlet pipe 11, and large particles of cotton wool impurities are filtered under the action of the filter basket 22, and some small particles of impurities pass through the filter basket 22 and flow down with the water. During the wastewater input process, the first motor 2 is turned on, and the first motor 2 drives the first rotating rod 21 to rotate, and the first rotating rod 21 drives the arc-shaped blade 214 to rotate, and the arc-shaped blade 214 scrapes the cotton wool on the inner wall of the filter basket 22; the air is shattered into bubbles by the high-speed rotation of the stirring paddle 212. If there are many small particles of cotton wool in the wastewater, the treatment cylinder 1 can also be pressurized by the pressure box to dissolve the air in the water, and then the pressure is reduced to release it to form microbubbles. By generating tiny bubbles, the bubbles are adhered to suspended matter, oil or solid particles in the water. , forming a "bubble-particle" complex with a density lower than that of water. After floating to the water surface, the adsorption cover 213 of the limiting mechanism is released, and the adsorption cover 213 rotates with the rotation of the first rotating rod 21. During the rotation, the adsorption pump 242 is turned on, and the suspended matter, oil or solid particles in the water adhere to the adsorption cover 213 and are adsorbed, and then transported to the collection box 243 through the telescopic tube 24 and the conveying pipe 241 respectively. When the adsorption cover 213 rotates 180 degrees, the first motor 2 is turned off, and the adsorption cover 213 is quickly reset under the action of the torsion spring, and can be reciprocated for several times. Then the limiting mechanism is lowered and the adsorption cover 213 is limited and fixed again, so that the cotton wool can be cleaned in all directions, preventing water pollution caused by the cotton wool and preventing the cotton wool from affecting subsequent treatment.

[0054] When adsorption is not required, the electric push rod 23 is turned on, and the electric push rod 23 drives the limit block 232 to move downward. The limit blocks 232 are respectively provided on the two ends of the adsorption cover 213 facing the wall, thereby locking the adsorption cover 213. When the first rotating rod 21 rotates, the adsorption cover 213 is unable to rotate due to resistance.

[0055] During adsorption, by releasing the fixation of the adsorption cover 213 by the limit block 232, when the first rotating rod 21 starts to rotate, a relative angle difference will appear 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 angle difference. Finally, the rotating plate will accelerate under the drive of the torsion spring torque, gradually approaching the rotation speed of the shaft, and when the adsorption cover 213 rotates 180 degrees, the impurities floating in the treatment cylinder 1 are cleaned.

[0056] After a period of time, a lot of cotton wool accumulates in the filter basket 22. When it needs to be cleaned, the second motor 224 is turned on, and the output shaft of the second motor 224 drives the push rod 223 to rotate, and the push block 222 is driven to rotate by the push rod 223, and the blocking plate 221 is driven to rotate by the push block 222. The blocking plate 221 releases the blockage of the discharge port, and then the first rotating rod 21 drives the arc blade 214 to rotate during the rotation process. The centrifugal force generated by the arc blade 214 during rotation throws the cotton wool into the discharge bin 227, thereby realizing the function of cleaning the cotton wool. The first motor 2 is a forward and reverse rotating motor.

[0057] The wastewater in the treatment drum 1 is transported to the mixing drum 3 through the connecting pipe 12 by the water pump 13. During the transport process, the impurities scraped off by the U-shaped scraper 211 and other impurities in the water are filtered by the filter. One of the medicine storage boxes 33 is used to place the neutralizer, and the other medicine storage box 33 is used to place the flocculant. The neutralizer is first added to the water for a neutralization reaction. After reaching a suitable pH value, the flocculant is added to facilitate the flocculation and sedimentation of the precipitate. To facilitate the flow of the neutralizer and flocculant, the drive motor 331 is turned on, and the output shaft of the drive 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 material. The amount of neutralizer and flocculant placed is determined according to the water level meter 37.

[0058] After the pH meter 38 has been used for a period of time, impurities in the water will adhere to the surface, affecting its detection accuracy. By turning on the fourth motor 382, ​​the fourth motor 382 drives the reciprocating screw 384 to rotate through the output shaft, and the reciprocating screw 384 drives the lifting plate 387 to reciprocate up and down, and the lifting plate 387 drives the pH meter 38 to reciprocate up and down. During the movement, the pH meter 38 rubs against the cleaning cotton 386, and the cleaning cotton 386 cleans the impurities on the surface.

[0059] The heating wire and the cooling tube 314 are used to heat and cool the wastewater in the mixing drum 3 respectively when in use. The temperature in the water is monitored by the temperature sensor 36. 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 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 the reactants. Heating allows the unreacted substances to continue to react until they are completely precipitated; but when the temperature is higher than the set value, the temperature sensor 36 transmits 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 generated precipitate may be redissolved. Cooling can accelerate the coagulation of colloidal particles and improve the filtration efficiency.

[0060] 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 .
