Description

Technical Field

[0001] The invention relates to an industrial wastewater treatment system and a use method thereof, belonging to the technical field of sewage treatment. Background Art

[0002] Industrial wastewater contains a large amount of pollutants. If it is discharged directly without treatment, it will cause serious environmental pollution. Therefore, it is necessary to carry out strict treatment. The commonly used sewage treatment method is to add chemicals to the sewage to precipitate the pollutants, and then filter or precipitate them before discharge.

[0003] For example, Chinese patent document CN111377565A discloses an industrial wastewater treatment device. When in use, wastewater is injected into the first box through the sewage inlet pipe. As the wastewater level in the first box rises, the wastewater drives the float to float upward, and the float drives the lightweight rod to move upward along the guide hole, and the lightweight rod drives the limit plate at the top to lift; when the wastewater is injected, the lightweight rod and the limit plate no longer move upward. At this time, the rack block is driven to engage with the rack by the extension of the second electric push rod, so that the lightweight rod cannot move up and down under the drive of the float; the adjustment plate is driven to move up by the extension of the first electric push rod, and the adjustment plate drives the piston to move up through the piston rod, and the piston draws the liquid medicine in the medicine supply barrel into the dosing chamber. When the adjustment plate moves upward to contact the lower side of the limit plate, the first electric push rod stops driving the adjustment plate to move up, and the piston stops extracting the liquid medicine, thereby realizing the proportional extraction of liquid medicine according to the height of the wastewater level in the first box.

[0004] The device first injects wastewater into the first tank, and then quantitatively injects liquid medicine into the first tank according to the amount of wastewater injected into the first tank. That is, the time when the wastewater and liquid medicine are injected into the first tank is completely staggered, which will greatly reduce the wastewater treatment efficiency of the device.

DETAILED DESCRIPTION

[0044] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0045] like Figures 1 to 12 As shown, an industrial wastewater treatment system described in the present invention includes a sedimentation tank 1, a first motor 2, a medicine box 6 and a sewage tank 8. The first motor 2 is installed on the sedimentation tank 1 through a motor bracket 3. The medicine box 6 is located above the sedimentation tank 1, and the bottom of the medicine box 6 is connected to the top of the sedimentation tank 1 through a liquid feeding pipe 27. A medicine delivery component is rotatably installed in the liquid feeding pipe 27, and one end of the medicine delivery component extends to the outside of the liquid feeding pipe 27 and is connected to the output shaft of the first motor 2. The sewage tank 8 is located above the sedimentation tank 1, and the bottom of the sewage tank 8 is connected to the top of the sedimentation tank 1 through a downpipe 11. A sewage delivery mechanism is rotatably installed in the downpipe 11, and one end of the sewage delivery mechanism extends to the outside of the downpipe 11 and is transmission-connected to the output shaft of the first motor 2. When in use, the downpipe 11 is connected to the sewage tank 8 and the sedimentation tank 1, and the liquid delivery pipe 27 is connected to the medicine box 6 and the sedimentation tank 1. The wastewater in the sewage tank 8 is discharged into the sedimentation tank 1 through the sewage discharge mechanism, and the medicine in the medicine box 6 is discharged into the sedimentation tank 1 through the medicine discharge assembly. The sewage discharge mechanism and the medicine discharge assembly are both driven by the first motor 2, so the purpose of adjusting the ratio of wastewater to medicine can be achieved by adjusting the transmission ratio of the first motor 2 and the sewage discharge mechanism and the medicine discharge assembly (that is, adjusting the diameters of the first transmission wheel 10 and the third transmission wheel 47). Once the ratio is adjusted, the wastewater and the medicine are discharged into the sedimentation tank 1 at the same time in proportion, so the wastewater treatment efficiency of the industrial wastewater treatment system can be improved as a whole.

[0046] The bottom of the medicine box 6 is also connected to the top of the sedimentation tank 1 via a support rod 5. A dosing port 7 is formed on the top of the medicine box 6, and a movable cover is installed on the medicine box 6 at the dosing port 7. The support rod 5 and the liquid feeding pipe 27 stably support the medicine box 6, and medicine can be added to the medicine box 6 through the dosing port 7. The movable cover is used to close the dosing port 7.

[0047] Two second curved plates 43 are symmetrically mounted on the inner wall of the liquid delivery tube 27, and the two second curved plates 43 are coaxially arranged with the medicine delivery assembly;

[0048] The drug delivery assembly includes a second central axis 45 and two third end plates 44. One end of the second central axis 45 is connected to the output shaft of the first motor 2, and the other end is inserted into the liquid delivery pipe 27 and rotatably connected to the liquid delivery pipe 27. The two third end plates 44 are mounted on the second central axis 45 and located within the liquid delivery pipe 27. The two third end plates 44 are connected by a plurality of blades 42. The plurality of blades 42 are evenly distributed relative to the second central axis 45, and one side of the blade 42 is fixedly connected to the second central axis 45, and the other side is tightly fitted with the second curved plate 43. During use, one side of the blade 42 is tightly fitted with the second curved plate 43 to prevent the drug from flowing downward through the gap between the two, which is conducive to accurately controlling and adjusting the ratio of the drug to wastewater delivered to the sedimentation tank 1. The reagent in the reagent box 6 flows down through the liquid delivery pipe 27. When the second central shaft 45 does not rotate, the blade 42 and the second curved plate 43 cooperate to block the liquid delivery pipe 27, preventing the reagent from continuing to flow downward into the sedimentation tank 1. The blade 42, the second central shaft 45, and the third end plate 44 together form multiple grooves A for holding the reagent. When a groove A is located on the upper side of the second central shaft 45, it is filled with reagent. When the first motor 2 rotates, the groove A located on the upper side of the second central shaft 45 gradually rotates to the lower side of the second central shaft 45 and pours out the reagent inside. The reagent is then gradually released into the lower half of the liquid delivery pipe 27 through the groove A. The reagent then enters the sedimentation tank 1 to react with the wastewater.

[0049] A second transmission wheel 46 and a third transmission wheel 47 are also mounted on the second central shaft 45 , and both the second transmission wheel 46 and the third transmission wheel 47 are located outside the liquid delivery pipe 27 .

[0050] The downpipe 11 is provided with a first partition 26, and a rectangular downspout is processed in the middle of the first partition 26. Two first curved plates 33 are symmetrically mounted on the inner wall of the rectangular downspout, and the two first curved plates 33 are coaxially arranged with the sewage delivery mechanism.

[0051] The sewage dispensing mechanism comprises a first central axis 37, a second end plate 38, and a plurality of second plug plates 32. One end of the first central axis 37 is inserted into the downpipe 11, with the middle portion extending through one sidewall of the downpipe 11 and being rotatably connected thereto. The other end extends outside the downpipe 11 and is fitted with a first transmission wheel 10. The first transmission wheel 10 is transmission-connected to the drug dispensing assembly via a first transmission belt 9. The second end plate 38 is fitted onto the first central axis 37 and positioned within the downpipe 11. A plurality of second plug plates 32 are evenly distributed on the first central axis 37. One end of each second plug plate 32 is connected to the second end plate 38, and the second plug plates 32 are tightly fitted to the first curved plate 33. During use, the first transmission wheel 10 is connected to the third transmission wheel 47 via the first transmission belt 9. Adjusting the diameter of the first transmission wheel 10 and / or the third transmission wheel 47 adjusts the transmission ratio between the second central axis 45 and the first central axis 37.

[0052] The second insert plate 32 has a V-shaped cross-section. The V-shaped tip of the second insert plate 32 is connected to the first central axis 37, and the V-shaped opening of the second insert plate 32 faces away from the first central axis 37. Both V-shaped ends of the second insert plate 32 are tightly fitted with the first curved plate 33. During use, the V-shaped ends of the second insert plate 32 are tightly fitted with the first curved plate 33, preventing wastewater from flowing downward through the gap between the two, which facilitates accurate control and adjustment of the ratio of reagent to wastewater released into the sedimentation tank 1. When a second insert plate 32 is located above the first central axis 37, its inner V-shaped groove is filled with wastewater. When the first central axis 37 rotates, the second insert plate 32 located above the first central axis 37 gradually rotates to the bottom of the first central axis 37 and pours out the wastewater inside. This gradually releases the wastewater into the lower half of the downpipe 11 through the second insert plate 32, where it then enters the sedimentation tank 1 to react with the reagent.

[0053] The sewage dispensing mechanism further includes a first end plate 25, a slide plate 39, and a second electric telescopic rod 24. The first end plate 25 is located within the downpipe 11 and is movably mounted on the first central axis 37. A plurality of first plug-ins 31 are evenly distributed on a side of the first end plate 25 near the second end plate 38, and a first plug-in plate 31 is partially inserted into a gap between two adjacent second plug-ins 32. One side of the first plug-in plate 31 contacts the first central axis 37, and the other side is tightly fitted with the first curved plate 33. A connecting ring 34 is mounted on a side of the first end plate 25 away from the second end plate 38, and the cross-section of the connecting ring 34 is L-shaped.

[0054] A through slot 56 is formed at one end of the slide plate 39 and is movably connected to the connecting ring 34. A sleeve 36 is mounted in the middle of the slide plate 39. The sleeve 36 is mounted on the first central axis 37 and fits tightly with the first central axis 37. The slide plate 39 fits tightly with the first curved plate 33. The slide plate 39 and the sleeve 36 both pass through the side wall of one side of the downpipe 11 and are slidably connected to the side wall.

[0055] The second electric telescopic rod 24 is connected to the downpipe 11 via the mounting plate 35, and is connected to the end of the sleeve 36 away from the first end plate 25. When in use, the first end plate 25 and the sleeve 36 support the end of the first central axis 37 away from the second end plate 38 to improve the rotational stability of the first central axis 37. One side of the first plug plate 31 fits tightly against the first curved plate 33, and the slide plate 39 fits tightly against the first curved plate 33 to prevent wastewater from flowing downward through the gap between them, which is conducive to accurately controlling and adjusting the ratio of the reagent and wastewater added to the sedimentation tank 1. Figure 5 and Figure 6As shown, the first plug plate 31 is partially inserted into the gap between two adjacent second plug plates 32. When the first central axis 37 rotates, the first plug plate 31 and the first end plate 25 are driven to rotate together through the second plug plate 32, so that the wastewater is gradually discharged into the sedimentation tank 1 through the V-shaped groove surrounded by the second end plate 38, the second plug plate 32, the first plug plate 31 and the first end plate 25.

[0056] A second motor 20 is installed on the top of the sedimentation tank 1. The output shaft of the second motor 20 extends into the sedimentation tank 1 and is connected to a connecting wheel 21. A plurality of stirring blades 22 are arranged in a circular array on the outer circumference of the connecting wheel 21.

[0057] The bottom plate of the sedimentation tank 1 is arranged at an angle. A discharge port 23 is opened on the side wall of the sedimentation tank 1 at the upper side of the lower end of the bottom plate. The discharge port 23 is covered by a baffle 12. The top of the baffle 12 is rotatably connected to the side wall of the sedimentation tank 1 via a connecting shaft 13. Two connecting plates 17 are installed in the middle of the baffle 12. The two connecting plates 17 are connected to the first rotating shaft 15 via a second rotating shaft 18 and a first electric telescopic rod 16. The first rotating shaft 15 is connected to the side wall of the sedimentation tank 1 via two fixed plates 14. During use, the second motor 20 drives the stirring blade 22 to rotate, thereby accelerating the mixing of the reagent and sewage. The extension and retraction of the first electric telescopic rod 16 can control the rotation of the baffle 12, thereby opening the discharge port 23 to discharge the sediment in the sedimentation tank 1.

[0058] A drainage tank 19 is installed on one side of the sedimentation tank 1. The top of the drainage tank 19 is connected to the top of the sedimentation tank 1 via a connecting pipe 4. The connecting pipe 4 is U-shaped, and a second partition plate 28 is installed above the sedimentation tank 1 at the end of the connecting pipe 4 near the sedimentation tank 1. The middle of the second partition plate 28 has a strip-shaped opening, and a filter plate 29 is installed inside the strip-shaped opening. Wastewater from the sedimentation tank 1 enters the drainage tank 19 through the connecting pipe 4 and is filtered at the filter plate 29. The filter plate 29 is located above the sedimentation tank 1 to prevent sediment from accumulating on the filter plate 29 and causing blockage.

[0059] A reciprocating screw 30, a polished rod 49 and a rack 50 are installed in parallel below the filter plate 29 in the connecting pipe 4. Both ends of the reciprocating screw 30 are rotatably connected to the connecting pipe 4, and one end of the reciprocating screw 30 extends to the outside of the connecting pipe 4 and is connected to the fourth transmission wheel 48. The fourth transmission wheel 48 is transmission-connected to the first motor 2 through the second transmission belt 40. A slide 52 is slidably connected to the polished rod 49, and the slide 52 is connected to the reciprocating screw 30 through a screw nut. Both ends of the slide 52 are fixedly installed with support plates 41, and the support plates 41 at both ends of the slide 52 are connected by a support shaft 55. A cleaning roller 51 is mounted on the support shaft 55, and a plurality of cleaning brushes 54 are evenly mounted on the outer circle of the cleaning roller 51, and the cleaning brushes 54 are in contact with the bottom surface of the filter plate 29. One end of the support shaft 55 is mounted with a gear 53, and the gear 53 is meshed with the rack 50. When the first motor 2 drives the second central shaft 45 to rotate, the second central shaft 45 drives the reciprocating screw 30 to rotate through the second transmission wheel 46, the second transmission belt 40 and the fourth transmission wheel 48, thereby driving the slide 52, the support plate 41 and the cleaning roller 51 to make reciprocating linear movements. During this process, the gear 53 at one end of the support shaft 55 remains engaged with the rack 50, thereby driving the cleaning roller 51 to rotate, and the cleaning brush 54 follows the cleaning roller 51 to rotate to clean the bottom surface of the filter plate 29 to prevent the filter plate 29 from being blocked.

[0060] A method for using an industrial wastewater treatment system comprises the following steps:

[0061] A. Start the first motor 2, which drives the sewage delivery mechanism to deliver wastewater from the sewage tank 8 into the sedimentation tank 1, drives the agent delivery assembly to deliver the agent from the agent box 6 into the sedimentation tank 1, and drives the reciprocating screw 30 to rotate, thereby driving the cleaning brush 54 to reciprocate and rotate to clean the filter plate 29;

[0062] B. Start the second motor 20 to drive the connecting wheel 21 and the stirring blade 22 to rotate, so as to stir and mix the wastewater and the reagent in the sedimentation tank 1;

[0063] C. Adjust the extension distance of the second electric telescopic rod 24 to achieve continuous and online adjustment of the ratio of wastewater and reagents fed into the sedimentation tank 1.

[0064] The industrial wastewater treatment system also includes a main controller, sub-controllers A and B. Sub-controllers A and B are connected to the main controller via a data transmission module. Sub-controller A is electrically connected to the first motor 2 and the second electric telescopic rod 24, while sub-controller B is electrically connected to the second motor 20. The data transmission module is a wireless data transmission module that enables remote control via the main controller. Similarly, the first electric telescopic rod 16 can also be controlled via sub-controller C. Sub-controller C is connected to the main controller via the data transmission module and is electrically connected to the first electric telescopic rod 16.

[0065] The industrial wastewater treatment system of the present invention works as follows:

[0066] The first motor 2 is started, and the first motor 2 drives the second central shaft 45 to rotate, thereby gradually putting the reagent into the sedimentation tank 1 through the multiple grooves A formed by the blade 42, the second central shaft 45 and the third end plate 44.

[0067] The second central shaft 45 drives the first central shaft 37 to rotate through the third transmission wheel 47, the first transmission belt 9 and the first transmission wheel 10, thereby gradually releasing the wastewater into the sedimentation tank 1 through the V-shaped groove surrounded by the second end plate 38, the second plug plate 32, the first plug plate 31 and the first end plate 25.

[0068] The second central shaft 45 drives the reciprocating screw 30 to rotate through the second transmission wheel 46, the second transmission belt 40 and the fourth transmission wheel 48, thereby driving the slide 52, the support plate 41 and the cleaning roller 51 to make reciprocating linear movements. During this process, the gear 53 at one end of the support shaft 55 remains engaged with the rack 50, thereby driving the cleaning roller 51 to rotate, and the cleaning brush 54 follows the rotation of the cleaning roller 51 to clean the bottom surface of the filter plate 29 to prevent the filter plate 29 from being blocked.

[0069] When it is necessary to adjust the ratio of wastewater to reagent, the rotational speed of the first central axis 37 and the second central axis 45 remains unchanged, and the amount of reagent added to the sedimentation tank 1 per unit time remains fixed.
