[0019] The efficient graded purification and cleaning method for textile and clothing wastewater is as follows:

[0020] S1: First, the wastewater is introduced into the water inlet pool through the water pipe and flows into the first filter chamber to be filtered by the filter cotton, and then passes through the filter chamber and the decolorization chamber for graded treatment, and is discharged through the drain pipe.

[0021] S2: The water flow will drive the rotating water wheel to rotate, causing the air pressure in the air cylinder to increase. The change in the amplitude of the air pressure detection meter reading is used to determine the change in the rotating water wheel's speed:

[0022] S3: When the reading of the air pressure detection gauge is large, it is judged that the speed of the rotating water wheel is slowing down, that is, the first filter chamber is blocked and the water flow is reduced. The drive motor group can be started to drive the rotating lifting rod to push the support plate and the filter cartridge up:

[0023] S4: The piston rod will rise during the rising of the support plate, which will generate negative pressure in the first pneumatic component and the suction component in turn, slowly sucking away the fluff in the first filter chamber, thereby cleaning the first filter chamber:

[0024] S5: When the supporting plate is lowered and reset as a whole, negative pressure is generated in the second pneumatic component and the impurity suction component to absorb the fluff in the second filter cavity, thus completing the processing step.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The above technical solution is provided with a pneumatic cylinder, a first air groove and a second air groove; when the piston rod is upward as a whole, negative pressure can be generated at the bottom of the inner cavity of the pneumatic cylinder, which will in turn cause the first air groove and the debris suction component to generate negative pressure and generate suction on the first filter cavity, so as to suck away the impurities and fluff in the first filter cavity and introduce them into the debris storage box; then when the piston rod descends and resets, negative pressure is generated in the inner cavity at the top of the pneumatic cylinder, and the fluff impurities in the second filter cavity are sucked into the debris storage box by the ventilation pipe, the second air groove and the debris suction component for storage, thereby finally achieving rapid cleaning and removal of the fluff impurities in the first filter cavity and the second filter cavity.

[0027] The present invention is provided with a rotating water wheel, a gear and a first return spring. When the water filtered by the first filter chamber falls, it will slowly drive the rotating water wheel to rotate, so that the gear rotation pushes the judgment tooth block upward, so that the first return spring generates air pressure. At this time, the air pressure detection meter reading, when the reading is stable and the amplitude is not large, it means that the speed of the rotating water wheel is normal. When the amplitude is large, it means that the speed is reduced, that is, the filter cotton in the first filter chamber is blocked and the filtering effect is poor. At this time, the driving motor group can be started, so that the rotating lifting rod drives the support plate and the filter cartridge to move upward, so that the bottom of the water inlet pool pushes the one-way valve disc to open and connect with the inner cavity of the second filter chamber, so as to realize the switching of the filtration and facilitate the subsequent filtration.

[0028] The present invention provides a second return spring, an exhaust groove and an exhaust valve flap. When the support plate rises, the piston rod is driven upward, so that the gas at the top of the pneumatic cylinder is pushed through the second air groove and the exhaust groove and exhaust valve flap on one side of the second air groove to be discharged, so that it rises smoothly. Then, when the driving motor group drives the rotating lifting rod to rotate one hundred and eighty degrees, the elastic force of the second return spring can push the piston rod to drive the support plate and the filter assembly to reset downward as a whole, and the gas at the bottom of the pneumatic cylinder will be discharged through the first air groove and the exhaust groove and exhaust valve flap on one side of the first air groove, thereby realizing the up and down cycle reset operation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 8As shown, the present invention provides a highly efficient graded purification device for textile and clothing wastewater; it comprises a wastewater treatment device body 1: a filter chamber 2, a decolorization chamber 3 and a biological treatment chamber 4, which are respectively arranged in the inner cavity of the wastewater treatment device body 1 from right to left; a support plate 5, which is slidably connected to the bottom of the inner cavity of the filter chamber 2; a filter assembly 6, which comprises a filter cartridge 601, the filter cartridge 601 is fixedly installed in the middle of the top of the wastewater treatment device body 1, and a first filter chamber 602 and a second filter chamber 603 are respectively opened at the upper and lower parts of the filter cartridge 601, and filter sponges 604 are fixedly installed on the inner walls of the first filter chamber 602 and the second filter chamber 603, and a water inlet pool 8 located at the top of the filter assembly 6 is fixedly installed on the inner wall of the filter chamber 2, and the filter cartridge 6 The inner wall of 01 is fixedly installed with a one-way valve flap 9 located between the first filter cavity 602 and the second filter cavity 603, the inner cavity of the filter chamber 2 is provided with a determination component 11 located at the lower back of the support plate 5, the inner wall of the filter chamber 2 is provided with a debris absorption component 16 at the front end of the support plate 5, and a trigger component 17 is fixedly installed in the middle of the bottom end of the support plate 5. The inner wall of the filter chamber 2 is respectively provided with a first pneumatic component 18 and a second pneumatic component 19 located between the trigger component 17 and the bottom of the debris absorption component 16. The support plate 5 and the filter cartridge 601 can move up and down so that the first pneumatic component 18 and the second pneumatic component 19 can absorb debris in the first filter cavity 602 and the second filter cavity 603 respectively through the debris absorption component 16.

[0040] When water flows out through the first filter chamber 602 or the second filter chamber 603 to drive the rotating water wheel 1101 to rotate, the air pressure detection gauge 13 can be read to determine whether the rotation speed of the rotating water wheel 1101 is stable. If it is not stable, it means that the filter cotton 604 in the first filter chamber 602 or the second filter chamber 603 is blocked by fluff. Then the driving motor group 14 can be started to drive the rotating lifting rod 15 and the elastic force of the second return spring 1703 to drive the filter cartridge 601 to move up and down as a whole, thereby realizing the switching use of the first filter chamber 602 and the second filter chamber 603.

[0041] like Figure 2 As shown, a middle drain pipe 7 is fixedly installed on the left side of the wastewater treatment device body 1, and the drain pipe 7 is fixedly connected to the inner cavity of the biological treatment chamber 4. A water pipe 10 located above the water inlet pool 8 is fixedly installed on the inner wall of the top of the wastewater treatment device body 1.

[0042] With the above solution, a water pipe 10 is provided, and an operator can connect an external pipeline through one end of the water pipe 10 , so that waste water can be introduced into the water inlet pool 8 through the water pipe 10 .

[0043] like Figure 8 As shown, the determination component 11 includes a rotating water wheel 1101, a gear 1102, a determination gear block 1103, an air cylinder 1104 and a first return spring 1105;

[0044] The rotating water wheel 1101 is movably sleeved on the bottom of the inner cavity of the filter chamber 2 and on the lower back of the support plate 5, the gear 1102 is fixedly sleeved on the left end of the rotating water wheel 1101 and inside the wastewater treatment device body 1, the judgment tooth block 1103 is movably installed on the inner wall of the wastewater treatment device body 1 and above the gear 1102, and the bottom is meshed with the surface of the gear 1102, the air cylinder 1104 is fixedly installed inside the wastewater treatment device body 1 and above the judgment tooth block 1103, the top of the judgment tooth block 1103 extends to the inner wall of the air cylinder 1104, and the first reset spring 1105 is fixedly installed between the middle of the top of the judgment tooth block 1103 and the inner wall of the air cylinder 1104.

[0045] By adopting the above scheme, a gear 1102 is provided. When the rotating water wheel 1101 is driven by the water flow to rotate, the judgment tooth block 1103 will rotate and push the judgment tooth block 1103 up, and the elastic force of the first reset spring 1105 will push it downward.

[0046] like Figure 7 and Figure 8 As shown, the middle part of the top of the air cylinder 1104 is fixedly connected with a connecting pipe 12, and the top of the connecting pipe 12 is provided with an air pressure detection gauge 13.

[0047] By adopting the above scheme, an air pressure detection gauge 13 is provided. When the rotating water wheel 1101 and the gear 1102 rotate constantly, the tooth block 1103 will maintain a continuous upward trend, thereby reducing the amplitude of the up and down movement, so that the amplitude of the air pressure change in the air cylinder 1104 is also reduced, and the data amplitude of the reading of the air pressure detection gauge 13 is also small, indicating that the filtering process is smooth and not blocked.

[0048] like Figure 7 As shown, a drive motor group 14 located below the support plate 5 is fixedly installed on the right side of the wastewater treatment device body 1, and the left side of the drive motor group 14 extends to the inner cavity of the filter chamber 2 and has rotating lifting rods 15 located below the support plate 5 fixedly sleeved on both sides.

[0049] The above scheme is adopted, and a driving motor group 14 is provided. When the amplitude of the reading of the air pressure detection gauge 13 becomes larger, the driving motor group 14 can be started at this time, so that the rotating lifting rod 15 pushes the support plate 5 and the filter cartridge 601 to move upward as a whole, so that the bottom end of the water inlet pool 8 is linked with the second filter chamber 603 to realize switching filtration.

[0050] like Figure 3 As shown, the impurity suction assembly 16 includes an impurity storage box 1601, a through pipe 1602, a sleeve 1603, and an impurity suction pipe 1604;

[0051] The debris storage box 1601 is movably installed in the inner cavity of the filter chamber 2 and the front end of the bottom of the support plate 5. The through pipe 1602 is fixedly connected to the middle of the top of the debris storage box 1601 and passes through the support plate 5. The sleeve 1603 is fixedly installed on the top of the support plate 5 and is sleeved on the surface of the through pipe 1602. The debris suction pipe 1604 is fixedly installed in the middle of the top of the water inlet pool 8, and the front end is movably sleeved with the top of the sleeve 1603.

[0052] By adopting the above scheme, a debris storage box 1601 is provided. When negative pressure is generated at one end of the debris suction pipe 1604 to respectively suck away the fluff inside the first filter chamber 602 and the second filter chamber 603, the fluff can be introduced into the debris storage box 1601 through the sleeve 1603 and the through pipe 1602. Then the operator can pull out the debris storage box 1601 to clean it for subsequent use.

[0053] like Figure 3 As shown, the trigger assembly 17 includes a pneumatic cylinder 1701, a piston rod 1702 and a second return spring 1703;

[0054] The pneumatic cylinder 1701 is fixedly installed in the middle of the bottom end of the inner cavity of the filter chamber 2 and below the support plate 5. The piston rod 1702 is movably sleeved in the inner cavity of the pneumatic cylinder 1701 and the top end is fixedly connected to the bottom of the support plate 5. The second return spring 1703 is fixedly installed between the top end of the piston rod 1702 and the inner wall of the pneumatic cylinder 1701.

[0055] By adopting the above scheme, a second reset spring 1703 is provided. When the driving motor group 14 rotates and drives the rotating lifting rod 15 to rotate one hundred and eighty degrees, the support for the support plate 5 and the filter cartridge 601 will be released. At this time, due to the gravity of the support plate 5 and the elastic force of the second reset spring 1703, the support plate 5 and the filter cartridge 601 can be driven to reset downward as a whole.

[0056] like Figure 4 As shown, the first pneumatic assembly 18 includes a first air groove 1801, a first one-way valve 1802, and a first spring 1803;

[0057] The first air groove 1801 is opened inside the wastewater treatment device body 1 and between the pneumatic cylinder 1701 and the inner side of the bottom end of the storage box 1601. The first one-way valve 1802 is movably connected to the front end of the inner wall of the first air groove 1801. The first spring 1803 is fixedly installed between the bottom end of the first one-way valve 1802 and the inner wall of the first air groove 1801.

[0058] By adopting the above scheme, a first air groove 1801 is provided. When the piston rod 1702 rises, suction is generated in the first air groove 1801, thereby driving the first one-way valve 1802 to descend, so that part of the gas in the suction component 16 is sucked away to generate negative pressure, so that the part extending from the middle of the bottom end of the water inlet pool 8 generates suction to absorb the fluff impurities in the first filter chamber 602 during the rising process of the filter cartridge 601.

[0059] like Figure 4 As shown, the second pneumatic assembly 19 includes a second air groove 1901, a vent pipe 1902, a second one-way valve 1903 and a second spring 1904;

[0060] The second air groove 1901 is opened on the inner wall of the wastewater treatment device body 1 and the bottom end of the first air groove 1801, and the front end is fixedly connected to the bottom of the first air groove 1801, the ventilation pipe 1902 is fixedly connected to the top of the back side of the pneumatic cylinder 1701, and the other end is fixedly connected to the second air groove 1901, the second one-way valve 1903 is movably sleeved on the front end of the inner wall of the first air groove 1801, the second spring 1904 is fixedly installed between the bottom end of the second one-way valve 1903 and the inner wall of the second air groove 1901, and the ventilation sponge 20 located at the top of the front end of the first air groove 1801 and the second air groove 1901 is fixedly installed at the bottom of the storage box 1601, and the inner wall of the wastewater treatment device body 1 is respectively provided with exhaust grooves 21 located on the right side of the first air groove 1801 and the second air groove 1901, and the exhaust valve flap 22 is fixedly installed on the right side of the inner wall of the exhaust groove 21.

[0061] By adopting the above scheme, a second air groove 1901 is provided. When the support plate 5, the filter cylinder 601 and the piston rod 1702 descend, negative pressure will be generated in the inner cavity at the top of the pneumatic cylinder 1701, causing the second one-way valve 1903 in the inner cavity of the second air groove 1901 to move downward, so that the negative pressure acts on the impurity suction component 16 and the part extending from the bottom of the water inlet pool 8 in turn, and finally the lint impurities in the second filter cavity 603 can be sucked away and cleaned up.

[0062] The working principle and use process of the present invention:

[0063] First, the operator can guide the wastewater into the water inlet pool 8 through the external water pipe of the water pipe 10. At this time, the wastewater will flow into the first filter chamber 602 through the water inlet pool 8. At this time, the filter sponge 604 can filter the wastewater, and then the water flow will drive the rotating water wheel 1101 to rotate, so that the gear 1102 rotates. At this time, due to the meshing relationship between the surface of the gear 1102 and the top of the judgment tooth block 1103, the judgment tooth block 1103 can be pushed upward, so that the air pressure of the first reset spring 1105 increases, and the air pressure detection meter 13 can read the reading. When the rotating water wheel 1101 When it rotates evenly, the reading will be stable with a small amplitude, which means that the first filter chamber 602 is not blocked. If the amplitude increases, it means that the rotation speed decreases, that is, the filter cotton 604 in the first filter chamber 602 is blocked by hair. Then the drive motor group 14 can be started to make the rotating lifting rod 15 rotate ninety degrees to push the support plate 5 and the filter cartridge 601 upward until the bottom of the water inlet pool 8 pushes the one-way valve flap 9 to open and connect with the inner cavity of the second filter chamber 603. Then the second filter chamber 603 and the filter cotton 604 in the inner cavity can be used to continue the filtering process.

[0064] Afterwards, when the support plate 5 and the filter cartridge 601 rise, the piston rod 1702 can be driven to rise in the inner cavity of the pneumatic cartridge 1701 at the same time, so that negative pressure is generated at the bottom of the inner cavity of the pneumatic cartridge 1701, so that negative pressure is generated in sequence through the first air groove 1801, the through pipe 1602 of the storage box 1601, the sleeve 1603 and the suction pipe 1604 to absorb the fluff and impurities in the first filter cavity 602, so as to absorb the impurities and fluff in the first filter cavity 602 and introduce them into the storage box 1601. Then, when switching back to the first filter chamber 602 for filtering, the second return spring 1703 will push the piston rod 1702 to return to its original position, causing negative pressure to be generated in the top inner cavity of the pneumatic cylinder 1701, and the lint impurities in the second filter chamber 603 will be sucked into the storage box 1601 by the ventilation pipe 1902, the second air groove 1901, and the impurity suction component 16 for storage, so as to quickly clean the lint impurities in the first filter chamber 602 and the second filter chamber 603.
