DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 6 As shown, a chemical wastewater purification and discharge device according to an embodiment of the present invention includes a wastewater purification tank 1; a support base 2 is installed at the bottom of the wastewater purification tank 1; a water inlet 3 is fixedly connected to the side wall of the wastewater purification tank 1; a water outlet 4 is fixedly connected to the bottom of the wastewater purification tank 1; a water level detector 5 is installed on the side wall of the wastewater purification tank 1; a first servo motor 6 is fixedly connected to the top of the wastewater purification tank 1; a stirring rod 7 is fixedly connected to the output end of the first servo motor 6; the stirring rod 7 extends to the interior of the wastewater purification tank 1 and is rotatably connected to the wastewater purification tank 1; a stirring blade 8 is fixedly connected to the end of the stirring rod 7; a second servo motor 9 is fixedly connected to the top of the wastewater purification tank 1; the second servo motor 9 output The outlet end is fixedly connected to a screw rod 10; the screw rod 10 extends into the interior of the sewage purification tank 1 and is rotatably connected to the sewage purification tank 1; a slider 11 is threadedly connected to the middle of the screw rod 10; a first guide rail 12 is fixedly connected to the interior of the sewage purification tank 1; a guide rod 13 is fixedly connected to the side wall of the slider 11; the end of the guide rod 13 is located inside the first guide rail 12 and is slidably connected to the first guide rail 12; a support rod 14 is fixedly connected to the side wall of the slider 11; a material refueling port is provided at the top of the sewage purification tank 1; a fixing seat 15 is fixedly connected to the end of the support rod 14; a holding box 16 is detachably fixed to the top of the fixing seat 15 by bolts; a box cover 1 is provided on the top of the holding box 16 7; the box cover 17 ceiling plate is fixedly connected with a corrosion-resistant pull rope 18; the top of the box cover 17 is installed with a dosing cover 19; the top of the sewage purification box 1 is slidably connected with a closing cover 102. During operation, after filtering the chemical sewage, the sewage is injected into the sewage purification box 1 from the water inlet 3, and then the switch of the first servo motor 6 is turned on to make the stirring blade 8 stir the sewage, and then the medicine is placed inside the containing box 16, and the end of the corrosion-resistant pull rope 18 is tied to the top of the sewage purification box 1, and then the switch of the second servo motor 9 is controlled to make the second servo motor 9 drive the screw rod 10 to rotate. At this time, the slider 11 on the screw rod 10 will move downward, through the first guide rail 12 and the guide rod 1 3 makes the slider 11 fall vertically stably. When the slider 11 drives the holding box 16 to a deeper position inside the sewage, the length of the corrosion-resistant pull rope 18 is pulled to the limit. In the process of the holding box 16 being driven down by the slider 11, the pulling of the corrosion-resistant pull rope 18 causes the box cover 17 and the holding box 16 to separate, thereby causing the liquid medicine inside the holding box 16 and the sewage inside the sewage purification tank 1 to mix. Because the liquid medicine is put into the sewage through the holding box 16, the mixing process of the liquid medicine and the sewage will be faster, thereby improving the efficiency of sewage purification and discharge. When the dosing is completed, the sewage is discharged from the water outlet 4, and then the holding box 16 is lifted up again by the slider 11 and reused.

[0023] like Figure 5 and Figure 6As shown, the top of the sewage purification box 1 is fixedly connected to a support plate 20; the side wall of the support plate 20 is fixedly connected to a third servo motor 21; the output end of the third servo motor 21 is fixedly connected to a connecting shaft 22; the middle part of the connecting shaft 22 is fixedly connected to a reel 23; the end of the corrosion-resistant pull rope 18 is fixedly connected to the middle of the reel 23. When working, the corrosion-resistant pull rope 18 and the reel 23 are connected. When the slider 11 drives the containing box 16 and the box cover 17 to move downward, the third servo motor 21 is controlled to drive the connecting shaft 22 to rotate, and then the corrosion-resistant pull rope 18 is unwound. When it is necessary to open the box cover 17 to mix the liquid medicine and sewage, the third servo motor 21 is stopped to drive The connecting shaft 22 rotates, and the corrosion-resistant pull rope 18 pulls up the box cover 17 to mix the medicine liquid and sewage. In the process of the slider 11 lifting the containing box 16 upward, the third servo motor 21 drives the connecting shaft 22 to rotate in the opposite direction, thereby reeling in the corrosion-resistant pull rope 18, reducing the possibility of the corrosion-resistant pull rope 18 becoming scattered and tangled, and improving the stability of the corrosion-resistant pull rope 18 during the movement of the containing box 16. At the same time, the third servo motor 21 adjusts the degree of unwinding of the corrosion-resistant pull rope 18, so that the box cover 17 can be opened at different positions in the sewage, and the medicine inside the containing box 16 can be mixed at different heights inside the sewage, thereby improving the adaptability of the device.

[0024] like Figure 6 As shown, a fixing rod 24 is fixedly connected to the bottom of the box cover 17; a pushing plate 25 is fixedly connected to the end of the fixing rod 24; the pushing plate 25 is slidably connected to the inner wall of the containing box 16. During operation, by providing a pushing plate 25 inside the containing box 16, when the box cover 17 is pulled by the corrosion-resistant pull rope 18 and then separated from the containing box 16, the pushing plate 25 is driven to slide upward from the bottom of the containing box 16, and the liquid medicine located inside the containing box 16 is pushed outward, so that the liquid medicine can enter the sewage faster and mix with the sewage, thereby improving the contact speed between the liquid medicine and the sewage and accelerating the mixing and purification effect of the liquid medicine on the sewage.

[0025] like Figure 6 As shown, a rubber ring 26 is fixed to the top of the containing box 16; a sealing groove 27 is opened at the bottom of the box cover 17; the rubber ring 26 and the sealing groove 27 are arranged correspondingly. During operation, by respectively arranging the rubber ring 26 and the sealing groove 27 between the containing box 16 and the box cover 17, the containing box 16 and the box cover 17 can have a better sealing effect when closing, thereby reducing the leakage of the liquid medicine during the descending process of the containing box 16 and causing premature mixing with sewage, reducing the problem of liquid medicine mixing effect, and improving the stability of the containing box 16 during operation.

[0026] like Figure 3As shown, an isolation plate 28 is fixedly connected to the inner wall of the sewage purification box 1; a pair of guide plates 29 are fixedly connected between the isolation plate 28 and the sewage purification box 1; a plurality of activated carbon plates 30 are provided between the guide plates 29; an exhaust pipe 101 is fixedly connected to the top of the sewage purification box 1. During operation, when the sewage is chemically neutralized, waste gas such as volatile organic compounds (VOCs) will be generated. Direct discharge of these waste gases will cause secondary pollution. Therefore, an exhaust pump is provided at the end of the exhaust pipe 101, and then the waste gas passes through a plurality of activated carbon plates 30 during the rising process and is then discharged to the outside through the exhaust pipe 101 by the exhaust pump. By providing the activated carbon plates 30 above the sewage, the waste gas generated during the neutralization process of the sewage can be purified by the activated carbon plates 30, thereby reducing the waste gas generated during the purification process of chemical sewage treatment, improving environmental protection and the safety of chemical sewage treatment purification discharge.

[0027] like Figure 3 and Figure 8 As shown, the inner wall of the guide plate 29 is fixed with a plurality of second guide rails 31; the second guide rails 31 are symmetrically arranged; the activated carbon plate 30 is detachably arranged; the top of the activated carbon plate 30 is fixed with a top cover 32; the top of the top cover 32 is fixed with a handle 33; the activated carbon plate 30 and the inner wall of the second guide rail 31 are in sliding fit. During operation, the activated carbon plate 30 that has been purified for a long time is pulled out from the interior of the sewage purification box 1 and replaced with a new activated carbon plate 30, and the new activated carbon plate 30 is inserted into the interior of the sewage purification box 1 along the second guide rail 31, so that the activated carbon plate 30 can be quickly and conveniently replaced, thereby enhancing the filtering effect of the activated carbon plate 30. At the same time, the second guide rail 31 is provided to make the installation of the activated carbon plate 30 more convenient and accurate.

[0028] like Figure 8 and Figure 9 As shown, the inner wall of the second guide rail 31 is rotatably connected to a plurality of anti-wear balls 34; the anti-wear balls 34 are arranged in an array in the second guide rail 31. When working, by providing the anti-wear balls 34 inside the second guide rail 31, the activated carbon plate 30 can move more smoothly inside the second guide rail 31 and reduce jamming.

[0029] like Figure 3 and Figure 4As shown, the top of the sewage purification box 1 is fixedly connected to an air pipe 35; the air pipe 35 passes through the isolation plate 28 and is fixed to the isolation plate 28; an air outlet 36 is opened at the end of the air pipe 35; a piston cylinder 37 is fixedly connected to the bottom of the sewage purification box 1; a piston plate 38 is slidably connected inside the piston cylinder 37; a piston rod 39 is fixedly connected to the top of the piston plate 38; the piston rod 39 passes through the piston cylinder 37 and is slidably connected to the piston cylinder 37; a top block 40 is fixedly connected to the end of the piston rod 39; the top block 40 is located inside the air pipe 35 and slides with the air pipe 35 When connected, during operation, hot steam is filled into the air pipe 35 by using a steam generator, so that the hot steam is discharged through the air outlet 36 and heats the sewage, so that the medicine and sewage can be better mixed and reacted. When the sewage temperature rises to a certain height, it is affected by the heat, and the expansion fluid pre-set in the piston cylinder 37 will expand, and then push the top block 40 upward, so that the top block 40 blocks the air outlet 36. At this time, the air pipe 35 can no longer transport hot steam to the sewage through the air outlet 36, thereby achieving the purpose of controlling the sewage temperature, which is more convenient and stable.

[0030] like Figure 3 and Figure 5 As shown, a tuning fork 41 is fixedly connected to the inner side wall of the sewage purification box 1; an elastic rod 42 is fixedly connected to the end of the screw rod 10; a rubber hammer 43 is fixedly connected to the end of the elastic rod 42; the rubber hammer 43 and the tuning fork 41 are correspondingly arranged. During operation, the screw rod 10 rotates and drives the elastic rod 42 to rotate, so that the rubber hammer 43 at the end of the elastic rod 42 strikes the tuning fork 41 at intervals, causing the tuning fork 41 to vibrate, thereby discharging the gas inside the sewage and improving the sewage purification effect.

[0031] like Figure 7 As shown, a scraper 44 is fixedly connected to the bottom of the guide rod 13; the end of the scraper 44 and the inner wall of the first guide rail 12 are arranged in contact with each other; the scraper 44 is arranged in an arc shape. When working, during the movement of the guide rod 13, the scraper 44 located at the bottom of the guide rod 13 scrapes the inner wall of the first guide rail 12, thereby cleaning the inner wall of the first guide rail 12, making the movement of the guide rod 13 smoother, and reducing the possibility of jamming of the guide rod 13.

[0032] During operation, after filtering the chemical wastewater, the wastewater is injected into the wastewater purification tank 1 from the water inlet 3, and then the switch of the first servo motor 6 is turned on to make the stirring blade 8 stir the wastewater. Then the medicine is placed in the containing box 16, and the end of the corrosion-resistant pull rope 18 is tied to the top of the wastewater purification tank 1. Then the switch of the second servo motor 9 is controlled to make the second servo motor 9 drive the screw 10 to rotate. At this time, the slider 11 on the screw 10 will move downward, and the slider 11 will fall stably and vertically through the setting of the first guide rail 12 and the guide rod 13. When the slider 11 drives the containing box 16 to descend After reaching a deeper position inside the sewage, the length of the corrosion-resistant pull rope 18 is pulled to the limit. In the process of the holding box 16 being continued to be driven down by the slider 11, the pulling of the corrosion-resistant pull rope 18 causes the box cover 17 and the holding box 16 to separate, thereby causing the medicine inside the holding box 16 and the sewage inside the sewage purification tank 1 to mix. Because the medicine liquid is injected into the sewage through the holding box 16, the mixing process of the medicine liquid and sewage will be faster, thereby improving the efficiency of sewage purification and discharge. When the medicine is added, the sewage is discharged from the water outlet 4, and then the holding box 16 is lifted up again by the slider 11 and reused.

[0033] The corrosion-resistant pull rope 18 is connected to the reel 23. When the slider 11 drives the containing box 16 and the box cover 17 to move downward, the third servo motor 21 is controlled to drive the connecting shaft 22 to rotate, thereby unwinding the corrosion-resistant pull rope 18. When the box cover 17 needs to be opened to mix the medical solution and sewage, the third servo motor 21 is stopped to drive the connecting shaft 22 to rotate, thereby causing the corrosion-resistant pull rope 18 to pull up the box cover 17 to mix the medical solution and sewage. In the process of the slider 11 lifting the containing box 16 upward, the third servo motor 21 is driven to reversely drive the connecting shaft 22 to rotate, thereby rewinding the corrosion-resistant pull rope 18, reducing the possibility of the corrosion-resistant pull rope 18 being scattered and tangled, and improving the stability of the corrosion-resistant pull rope 18 during the movement of the containing box 16. At the same time, the unwinding degree of the corrosion-resistant pull rope 18 by the third servo motor 21 enables the box cover 17 to be opened at different positions of the sewage, thereby enabling the medical solution inside the containing box 16 to be mixed at different heights inside the sewage, thereby improving the adaptability of the device.

[0034] By providing a push plate 25 inside the containing box 16, when the box cover 17 is pulled by the corrosion-resistant pull rope 18 and thus separated from the containing box 16, the push plate 25 is driven to slide upward from the bottom of the containing box 16, and the liquid medicine inside the containing box 16 is pushed outward, so that the liquid medicine can enter the sewage faster and mix with the sewage, thereby increasing the contact speed between the liquid medicine and the sewage and accelerating the mixing and purification effect of the liquid medicine on the sewage.

[0035] By respectively arranging a rubber ring 26 and a sealing groove 27 between the containing box 16 and the box cover 17, the containing box 16 and the box cover 17 can be made to have a better sealing effect when they are closed, thereby reducing the leakage of the liquid medicine during the lowering process of the containing box 16 and causing it to mix with the sewage in advance, reducing the problem of liquid medicine mixing effect, and improving the stability of the containing box 16 during operation.

[0036] When sewage is chemically neutralized, waste gases such as volatile organic compounds (VOCs) are generated. Direct discharge of these waste gases will cause secondary pollution. Therefore, an exhaust pump is provided at the end of the exhaust pipe 101, and the waste gas is allowed to pass through multiple activated carbon plates 30 during its rise and then be discharged to the outside through the exhaust pipe 101 by the exhaust pump. By providing the activated carbon plates 30 above the sewage, the waste gas generated during the sewage neutralization process can be purified by the activated carbon plates 30, thereby reducing the waste gas generated during the chemical sewage treatment and purification process, thereby improving environmental protection and the safety of chemical sewage treatment, purification and discharge.

[0037] By extracting the activated carbon plate 30 that has been purified for a long time from the interior of the sewage purification box 1 and replacing it with a new activated carbon plate 30, the new activated carbon plate 30 is inserted into the interior of the sewage purification box 1 along the second guide rail 31, so that the activated carbon plate 30 can be replaced quickly and conveniently, thereby enhancing the filtering effect of the activated carbon plate 30. At the same time, the second guide rail 31 can make the installation of the activated carbon plate 30 more convenient and accurate.

[0038] By providing the anti-wear balls 34 inside the second guide rail 31 , the activated carbon plate 30 can move more smoothly inside the second guide rail 31 and reduce jamming.

[0039] By using a steam generator to fill the air pipe 35 with hot steam, the hot steam is discharged through the air outlet 36 and heats the sewage, so that the agent and sewage can be better mixed and reacted. When the sewage temperature rises to a certain level, the expansion fluid pre-set in the piston cylinder 37 will expand under the influence of heat, and then push the top block 40 upward, so that the top block 40 blocks the air outlet 36. At this time, the air pipe 35 can no longer transport hot steam into the sewage through the air outlet 36, thereby achieving the purpose of controlling the sewage temperature, which is more convenient and stable.

[0040] By rotating the screw rod 10 and driving the elastic rod 42 to rotate, the rubber hammer 43 at the end of the elastic rod 42 will strike the tuning fork 41 at intervals, causing the tuning fork 41 to vibrate, thereby discharging the gas inside the sewage and improving the sewage purification effect.

[0041] During the movement of the guide rod 13, the scraper 44 located at the bottom of the guide rod 13 scrapes the inner wall of the first guide rail 12, thereby cleaning the inner wall of the first guide rail 12, making the movement of the guide rod 13 smoother and reducing the possibility of jamming of the guide rod 13.
