Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a comprehensive wastewater pollution treatment device for agricultural pesticide production. Background Art

[0002] A large amount of wastewater is generated during the pesticide production process, and the wastewater discharged during the pesticide production process contains various chemical substances. If this wastewater is directly discharged into water bodies, it will cause serious pollution to the water environment. The harmful substances in the wastewater may penetrate into groundwater through seepage, further polluting water resources, and will also pollute the soil and the ecosystem. Therefore, it is necessary to comprehensively treat the wastewater generated during the pesticide production process before discharging it to avoid polluting the environment. Among them, activated carbon is widely used in the treatment of pesticide wastewater due to its adsorption and other characteristics.

[0003] The publication number CN118373565B discloses a wastewater treatment device for feed oil production, which aims to make the overall activated carbon be placed in layers through the settings of adsorption box one and adsorption box two, and through the cooperation of the flipping mechanism, after the activated carbon on the top layer loses its adsorption effect, the wastewater can be automatically in direct contact with the activated carbon in the middle and bottom layers, avoiding the activated carbon on the top layer covering the surface of the activated carbon in the middle and bottom layers, enabling the activated carbon to be effectively utilized and improving the overall adsorption effect.

[0004] Combining the existing technologies, the following problems exist:

[0005] In the process of treating wastewater by the existing comprehensive wastewater pollution treatment device for agricultural pesticide production with activated carbon, usually the wastewater is directly in contact with the activated carbon under the action of centrifugal force, which is not convenient for the wastewater to flow evenly before contacting the activated carbon, resulting in local saturation of the activated carbon and incomplete treatment of the wastewater, affecting the treatment effect. And usually during the treatment process, the activated carbon needs to be replaced, resulting in the interruption of treatment, not being convenient for continuously treating the wastewater, and reducing the treatment efficiency. Referring to the above application document, although it makes the activated carbon be designed in layers, which is convenient for treating wastewater with different water volumes through activated carbon with different heights, the contact between the wastewater and the activated carbon is still uneven, resulting in incomplete treatment of the wastewater, and it is not convenient for continuously treating the wastewater, having certain deficiencies. For this reason, a comprehensive wastewater pollution treatment device for agricultural pesticide production is proposed. Summary of the Invention

[0006] In order to overcome the deficiencies of the above-mentioned existing technologies, the present invention provides a comprehensive wastewater pollution treatment device for agricultural pesticide production, which is convenient for the wastewater to flow evenly before contacting the activated carbon, improves the wastewater treatment effect, and is convenient for continuously treating the wastewater, improving the treatment efficiency.

[0025] The lifting lugs are fixedly arranged on both sides of the outer wall of the third retaining ring and both sides of the top of the rubber ring to lift the third retaining ring and the cloth bag.

[0034] The present invention provides a comprehensive treatment device for agricultural pesticide production wastewater pollution. Compared with the prior art, it has the following beneficial effects:

[0035] 1. In the present invention, the centrifugal mechanism evenly discharges the wastewater onto the cloth bags filled with activated carbon in the first processing mechanism and the second processing mechanism. Thus, the organic pollutants and heavy metal ions in the wastewater are treated by the activated carbon, the water quality of the wastewater is improved, the color and odor in the water are removed, the sensory index of the water quality is enhanced, and by setting the first processing mechanism and the second processing mechanism, it is convenient to continuously treat the wastewater and improve the treatment efficiency.

[0036] 2. Under the action of centrifugal force in the present invention, the wastewater is evenly dispersed on the inner wall of the second water guide cylinder and then evenly discharged, so that the wastewater is evenly in contact with the activated carbon, avoiding the situation that the wastewater only contacts with local activated carbon or a large amount of wastewater rushes onto the surface of the activated carbon at one time. Thus, the activated carbon can fully adsorb the impurities in the wastewater, etc., avoiding local saturation of the activated carbon and preventing incomplete treatment of the wastewater in subsequent treatment, so as to facilitate the full treatment of the wastewater.

[0037] 3. After the activated carbon in the first treatment mechanism or the second treatment mechanism is saturated, the corresponding saturated first treatment mechanism or second treatment mechanism is lifted, which facilitates the continuous treatment of wastewater and enables the staff to process the saturated activated carbon outside the box, reducing the work intensity of the staff and the contact between pesticides and the staff, and reducing the damage of pesticides to the staff.

[0038] 4. The lifting mechanism of the present invention facilitates the pulling out of the cloth bag filled with saturated activated carbon for the replacement of the activated carbon. During the pulling out process, the placement through groove between the cloth bag and the third connecting ring and the fourth connecting ring is tightened, so as to squeeze out the wastewater adsorbed on the surface, avoid the flowing of wastewater everywhere, and facilitate the subsequent replacement and use.

[0039] 5. The first pressure sensor and the second pressure sensor of the present invention facilitate the grasping of the saturation degree of the activated carbon after adsorption, so as to facilitate the judgment of whether to lift and replace the activated carbon according to the monitored information, which is convenient for actual use. By setting multiple first pressure sensors and second pressure sensors to monitor from different positions, the monitoring stability is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0062] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , a comprehensive treatment equipment for agricultural pesticide production wastewater pollution, including a box body 1, a water inlet pipe 2 and a drain pipe 4 respectively arranged at the top water inlet end and the bottom drain end of the box body 1 to discharge and drain the wastewater for agricultural pesticide production into and out of the box body 1 successively. It also includes a first treatment mechanism 6 arranged inside the box body 1, a second treatment mechanism 7 arranged inside the first treatment mechanism 6, and a centrifugal mechanism 9 arranged inside the second treatment mechanism 7. Through the cooperation of the centrifugal mechanism 9, the first treatment mechanism 6 and the second treatment mechanism 7, after the wastewater is evenly thrown away, the wastewater is then purified. The centrifugal mechanism 9 includes:

[0063] A first water guide cylinder 91, rotatably arranged inside the box body 1. A support mechanism 5 for installing the first water guide cylinder 91 is arranged on the inner side wall of the box body 1. A second water guide cylinder 95 is rotatably arranged on the inner wall of the first water guide cylinder 91 and is in contact with the outer wall of the second water guide cylinder 95. The drainage end of the water inlet pipe 2 is connected to the top of the first water guide cylinder 91 to enable the wastewater to enter the second water guide cylinder 95;

[0064] A connecting cylinder 92, fixedly arranged at the bottom of the first water guide cylinder 91 to block the bottom of the first water guide cylinder 91. A rotating rod 97 extending to the bottom of the box body 1 is fixedly arranged on the inner wall of the second water guide cylinder 95 to enable the first water guide cylinder 91 and the second water guide cylinder 95 to rotate synchronously and relatively.

[0065] The centrifugal mechanism 9 further includes:

[0066] A first servo motor 94, fixedly arranged on the outer wall of the box body 1. A transmission mechanism is arranged on the output shaft of the first servo motor 94 to enable the first servo motor 94 to drive the connecting cylinder 92 to rotate through the transmission mechanism, thereby driving the first water guide cylinder 91 to rotate;

[0067] A second servo motor 93, fixedly arranged at the bottom of the connecting cylinder 92. The output shaft of the second servo motor 93 is fixedly connected to the rotating rod 97 through a coupling, and the rotating rod 97 is rotatably connected to the connecting cylinder 92.

[0068] Spaces without water guide holes are reserved at the upper and lower ends of the first water guide cylinder 91 and the second water guide cylinder 95. Annular chutes 96 are respectively arranged at the upper and lower inner walls of the first water guide cylinder 91. Annular sliders are placed inside the annular chutes 96. The inner walls of the annular sliders are fixedly connected to the outer wall of the second water guide cylinder 95 to limit the rotation of the first water guide cylinder 91 and the second water guide cylinder 95;

[0069] The outer wall diameter of the connecting cylinder 92 gradually decreases from top to bottom. The connecting cylinder 92 penetrates through the drain pipe 4, and the connection with the drain pipe 4 is designed to be sealed.

[0070] During specific implementation, the wastewater enters the second water guiding cylinder 95 through the water inlet pipe 2. At the same time, the first servo motor 94 is started. The first servo motor 94 drives the connecting cylinder 92 to rotate through a transmission structure. The connecting cylinder 92 drives the first water guiding cylinder 91 and the second water guiding cylinder 95 to rotate synchronously, so that the wastewater in the second water guiding cylinder 95 is discharged along the water guiding holes on the side walls of the second water guiding cylinder 95 and the first water guiding cylinder 91, and is discharged onto the cloth bags 692 filled with activated carbon in the first treatment mechanism 6 and the second treatment mechanism 7. Thus, the organic pollutants and heavy metal ions in the wastewater are treated by the activated carbon, the water quality of the wastewater is improved, the color and odor in the water are removed, and the sensory index of the water quality is enhanced.

[0071] The bottom of the first water guiding cylinder 91 is blocked by the connecting cylinder 92. The water inlet pipe 2 is connected to the top of the first water guiding cylinder 91, and the inner wall of the first water guiding cylinder 91 is attached to the outer wall of the second water guiding cylinder 95, so that the wastewater enters the second water guiding cylinder 95. Under the action of centrifugal force, the wastewater is evenly dispersed on the inner wall of the second water guiding cylinder 95 and is evenly discharged along the water guiding holes on the side walls of the first water guiding cylinder 91 and the second water guiding cylinder 95. Thus, the wastewater is evenly in contact with the activated carbon, avoiding the situation that the wastewater only contacts with partial activated carbon or a large amount of wastewater surges onto the surface of the activated carbon at one time, so that the activated carbon can fully adsorb the impurities in the wastewater, etc., avoiding the saturation of partial activated carbon and preventing the situation that the wastewater is not fully treated in the subsequent treatment, thus facilitating the full treatment of the wastewater.

[0072] The second servo motor 93 drives the rotating rod 97 to rotate. The rotating rod 97 drives the second water guiding cylinder 95 to rotate, thereby adjusting the overlapping degree of the water guiding holes on the side walls of the first water guiding cylinder 91 and the second water guiding cylinder 95, so as to adjust the amount of wastewater discharged from the second water guiding cylinder 95, thus facilitating adjustment according to the actual treatment situation. For example, when the first treatment mechanism 6 is lifted, the first treatment mechanism 6 is relatively farther than the first treatment mechanism 6. At this time, the overlapping degree can be reduced or the centrifugal force can be increased to enable the wastewater to be discharged to the inside of the second treatment mechanism 7.

[0073] By enabling the first water guiding cylinder 91 and the second water guiding cylinder 95 to rotate synchronously or relatively, it is convenient to evenly discharge the wastewater through centrifugal force, and it is also convenient to adjust the amount of wastewater discharged, etc., which is convenient for actual use.

[0074] The water inlet pipe 2 is connected to the first water guiding cylinder 91 through a rotary joint, so that the water inlet pipe 2 does not rotate when the first water guiding cylinder 91 rotates, which is convenient for actual water supply use.

[0075] By making the outer diameter of the connecting cylinder 92 gradually decrease from top to bottom, it is convenient for the first servo motor 94 to drive the connecting cylinder 92 to rotate, and at the same time, it is convenient for the connecting cylinder 92 to pass through the drain pipe 4 without affecting the normal discharge of wastewater from the drain pipe 4.

[0076] The transmission mechanism includes a rotating shaft, a transmission gear and a chain. The rotating shaft is fixedly arranged at the output shaft of the first servo motor 94 through a coupling. The transmission gears are respectively fixedly sleeved on the outer walls of the rotating shaft and the connecting cylinder 92. The chain drives the two transmission gears, so that the first servo motor 94 drives the connecting cylinder 92 to rotate. A protective cover is arranged outside the transmission gear and the chain.

[0077] Please refer to Figure 7 and Figure 9 , the support mechanism 5 includes:

[0078] The support plate 52 is fixedly arranged on the inner side wall of the box body 1. Annularly spaced water guiding through grooves are formed at the top of the support plate 52, so that the purified wastewater flows to the lower end of the box body 1;

[0079] The support disk 51 is fixedly arranged on the top of the support plate 52. A bearing seat is fixedly arranged on the top of the support plate 52 and inside the support disk 51. A bearing for rotatably installing the first water guiding cylinder 91 is arranged on the inner wall of the bearing seat. A spacing is left between the outer wall of the bearing seat and the inner wall of the support disk 51;

[0080] The support grooves 53 are spacedly arranged on the top of the support disk 51 and are annularly designed.

[0081] In specific implementation, the first water guiding cylinder 91 is limited by the support plate 52, the bearing seat and the bearing, improving the stability of its rotation.

[0082] Through the water guiding through grooves, it is convenient to drain the wastewater purified by activated carbon to the lower end of the box body 1, so as to facilitate the discharge of the box body 1.

[0083] By making the bottom of the protective cover tightly fit and seal with the bottom of the support plate 52, and not arranging water guiding through grooves at the position on the top of the support plate 52 and directly above the protective cover, pesticides are prevented from entering the protective cover, thereby preventing pesticides from flowing out of the chain to the outside of the box body 1.

[0084] Embodiment 2: Please refer to Figure 5 , Figure 9 , Figure 10 , Figure 11 and Figure 13 , the different technical solution of this embodiment compared with Embodiment 1 is that the first treatment mechanism 6 includes:

[0085] The bottom plate 63 is sleeved in the support groove 53 and is designed in a ring shape. The outer side and the inner side of the top of the bottom plate 63 are respectively fixedly provided with a first connecting ring 69 and a second connecting ring 68, so as to form a placement groove 691 for placing activated carbon between the first connecting ring 69 and the second connecting ring 68. The tops of the first connecting ring 69 and the second connecting ring 68 are respectively fixedly provided with a first stop bar 61 and a second stop bar 64. Both the first stop bar 61 and the second stop bar 64 are arranged in a circular array. The tops of the first stop bar 61 and the second stop bar 64 are respectively fixedly provided with a third connecting ring 67 and a fourth connecting ring 66, so as to form a placement through groove 65 for disassembling and assembling activated carbon between the third connecting ring 67 and the fourth connecting ring 66;

[0086] The cloth bag 692 is used for storing activated carbon and is designed in a long strip shape, so that after the cloth bag 692 is bent, its upper end and lower end are respectively placed in the placement through groove 65 and the placement groove 691.

[0087] The first treatment mechanism 6 further includes:

[0088] The first pressure sensor 62 is fixedly arranged on the side wall of the first stop bar 61. The detection end of the first pressure sensor 62 is located between the first stop bar 61 and the second stop bar 64. The first pressure sensors 62 are arranged at intervals in a circular shape and are respectively distributed at the upper end, the middle end and the lower end of the first stop bar 61, so as to monitor the expansion degree of the cloth bag 692;

[0089] The second pressure sensor 693 is fixedly arranged on the inner wall of the bottom of the support groove 53 in a circular array, so as to monitor the weight of the cloth bag 692.

[0090] The first treatment mechanism 6 further includes:

[0091] The rubber ring 695 is fixedly arranged at the top of the cloth bag 692, and the thickness of the rubber ring 695 is greater than the thickness of the cloth bag 692 after being filled with activated carbon;

[0092] The lifting lugs 694 are fixedly arranged on both sides of the outer wall of the third retaining ring 71 and both sides of the top of the rubber ring 695, so as to lift the third retaining ring 71 and the cloth bag 692. A lifting mechanism 3 for lifting the cloth bag 692 and the third retaining ring 71 is arranged at the top of the box body 1.

[0093] Please refer to Figure 5 and Figure 12 The second treatment mechanism 7 includes the same structure as that of the first treatment mechanism 6 except for the different dimensions, so that the second treatment mechanism 7 is arranged inside the first treatment mechanism 6, and the second treatment mechanism 7 further includes:

[0094] The retaining ring 71 is fixedly arranged on the inner wall of the fourth connecting ring 66 of the second treatment mechanism 7, and the lifting lug 694 used for lifting in the second treatment mechanism 7 is fixedly arranged on the top of the retaining ring 71. A limiting mechanism 8 is arranged between the first treatment mechanism 6 and the second treatment mechanism 7 for limiting them.

[0095] In specific implementation, when the wastewater is discharged onto the activated carbon in the first treatment mechanism 6 and the second treatment mechanism 7 through the centrifugal mechanism 9, the activated carbon adsorbs the impurities in the wastewater, thereby purifying the wastewater.

[0096] By arranging the first stop strip 61 and the second stop strip 64, it is convenient to limit the cloth bag 692 filled with activated carbon, and reduce the shielding of the activated carbon, so that the wastewater can contact the activated carbon, thereby facilitating the treatment of the wastewater. Usually, three second stop strips 64 are provided to facilitate the setting of the first pressure sensor 62 at different positions and reduce the shielding of the activated carbon. The specific number of the second stop strips 64 can be adjusted according to actual use requirements and will not be elaborated here.

[0097] The placement groove 691 is formed by the first connecting ring 69 and the second connecting ring 68, which is convenient for supporting the cloth bag 692 filled with activated carbon and improving its stability. The placement through groove 65 is formed by the third connecting ring 67 and the fourth connecting ring 66, which is convenient for placing the cloth bag 692 filled with activated carbon at the placement groove 691 and the placement through groove 65. And by designing the thickness of the rubber ring 695, the rubber ring 695 can be tightly attached to the inner wall of the placement through groove 65, thereby limiting the cloth bag 692 filled with activated carbon and improving its stability. And the adsorption principle of activated carbon usually includes physical adsorption and chemical adsorption. In the process of chemical adsorption, the functional groups on the surface of the activated carbon can react with pollutants to form chemical bonds, thereby fixing the pollutants on the activated carbon. This adsorption is irreversible, and the adsorption heat is relatively large, which will cause the volume of the activated carbon to expand, so that the cloth bag 692 filled with activated carbon can be set more stably in the placement groove 691 and the placement through groove 65.

[0098] By arranging the first treatment mechanism 6 and the second treatment mechanism 7, after the activated carbon in the first treatment mechanism 6 or the second treatment mechanism 7 is saturated with adsorption, through the lifting mechanism 3, the corresponding saturated first treatment mechanism 6 or second treatment mechanism 7 can be lifted, which is convenient for continuous treatment of the wastewater, and is convenient for the staff to treat the saturated activated carbon outside the box body 1, reducing the work intensity of the staff, reducing the contact between the pesticide and the staff, and reducing the damage of the pesticide to the staff.

[0099] By arranging the retaining ring 71 to shield the top between the inner side of the second treatment mechanism 7 and the first water guide cylinder 91, it is possible to prevent the wastewater from splashing everywhere, and after the second treatment mechanism 7 is lifted, it can still play a shielding role, which is convenient for actual wastewater treatment.

[0100] The first pressure sensor 62 and the second pressure sensor 693 facilitate grasping the saturation degree of the activated carbon after adsorption, so as to facilitate judging whether to lift and replace the activated carbon according to the monitored information, which is convenient for actual use. By arranging a plurality of first pressure sensors 62 and second pressure sensors 693 to monitor from different positions, the monitoring stability is improved.

[0101] Please refer to Figure 14 , the limiting mechanism 8 includes:

[0102] The limiting plate 81 is fixedly arranged on the top of the support plate 51 and is located between the support grooves 53. T-shaped sliding grooves 82 are opened on both sides of the limiting plate 81. Sliders adapted to them are placed inside the T-shaped sliding grooves 82, and the sliders are fixedly connected to the second connecting ring 68 and the first connecting ring 69 of the first processing mechanism 6 and the second processing mechanism 7 respectively. Springs are sleeved on the tops of the sliders inside the T-shaped sliding grooves 82.

[0103] In specific implementation, when the lifting mechanism 3 drives the first processing mechanism 6 to lift, the second connecting ring 68 of the first processing mechanism 6 drives the slider to move along the T-shaped sliding groove 82, thereby limiting the lifting of the first processing mechanism 6 and improving the lifting stability. When the second processing mechanism 7 is lifted, the first connecting ring 69 of the second processing mechanism 7 drives the slider to move along the T-shaped sliding groove 82, thereby limiting the movement of the second processing mechanism 7 and improving its movement stability.

[0104] By arranging the springs, the sliders have a tendency to move downward, thereby limiting the first processing mechanism 6 and the second processing mechanism 7 and improving the stability. And the limiting plate 81 is located on the top of the third connecting ring 67 and the fourth connecting ring 66, so that the springs have enough compression space to avoid affecting the movement space of the first processing mechanism 6 and the second processing mechanism 7.

[0105] Please refer to Figure 15 , the lifting mechanism 3 includes:

[0106] Electric sliding rails are arranged at intervals on the top of the box body 1 and there is a space between them and the top of the box body 1. Winches are fixedly arranged at the sliding ends of the electric sliding rails, and the winches are double-hook winches.

[0107] In specific implementation, the hook at the bottom of the winch is used to hang the lug 694, so that the corresponding first treatment mechanism 6 and the second treatment mechanism 7 can be lifted. And by setting two winches, after the first treatment mechanism 6 or the second treatment mechanism 7 is lifted, the other winch is used to hang the lug 694 at the top of the rubber ring 695, so as to facilitate pulling out the cloth bag 692 filled with saturated activated carbon, which is convenient for replacing the activated carbon. And during the pulling process, the cloth bag 692 is closely attached to the placement through groove 65 between the third connecting ring 67 and the fourth connecting ring 66, so as to squeeze out the wastewater adsorbed on the surface, thus preventing the wastewater from flowing around and facilitating subsequent replacement and use.

[0108] When the present invention is implemented, the wastewater for agricultural pesticide production enters the centrifugal mechanism 9 through the water inlet pipe 2. Through the centrifugal mechanism 9, the wastewater is thrown out along the water guide holes on the side walls of the first water guide cylinder 91 and the second water guide cylinder 95 under the action of centrifugal force, so that the wastewater uniformly contacts the activated carbon of the first treatment mechanism 6 and the second treatment mechanism 7. Thus, the wastewater is purified by the activated carbon to reduce the removal of organic pollutants in the wastewater, such as refractory organic matters like pesticides, phenols, dyes, etc. The wastewater treatment effect is improved, and heavy metal ions such as lead and mercury can be removed. In addition, the water quality can be improved. The activated carbon can remove the color and odor in the water and improve the sensory index of the water quality. The wastewater purified by the first treatment mechanism 6 and the second treatment mechanism 7 flows to the lower end of the box body 1 and is discharged from the box body 1 along the drain pipe 4 to enter the next treatment link.

[0109] By setting the first treatment mechanism 6 and the second treatment mechanism 7, and arranging the second treatment mechanism 7 inside the first treatment mechanism 6, after the activated carbon in the first treatment mechanism 6 or the second treatment mechanism 7 is saturated with adsorption, through the lifting mechanism 3, the corresponding saturated first treatment mechanism 6 or second treatment mechanism 7 can be lifted, which is convenient for continuously treating the wastewater, and is convenient for the staff to process the saturated activated carbon outside the box body 1, reducing the work intensity of the staff, and reducing the contact between pesticides and the staff, and reducing the damage of pesticides to the staff.
