Description

Technical Field

[0001] This invention relates to the field of pesticide wastewater denitrification equipment, specifically a total nitrogen detection and treatment device for pesticide production wastewater. Background Technology

[0002] The production of pesticides generates a large amount of wastewater containing nitrogen. When this nitrogen-containing wastewater is discharged into clean water sources, it causes eutrophication and water quality deterioration, which in turn affects the growth and reproduction of aquatic organisms and causes great harm to the ecological environment. In the wastewater treatment process, nitrifying bacteria and aeration are generally used in combination to achieve nitrogen removal.

[0003] The following problems were found in the existing technology that have not been adequately addressed: 1. In the existing wastewater denitrification process, the aeration equipment is always located at the bottom of the wastewater treatment tank, which makes it difficult for the nitrifying bacteria in the upper part of the tank to react efficiently with oxygen for metabolism. The oxygen uniformity inside the treatment tank is poor, which affects the denitrification effect in the upper part of the wastewater pipe; 2. Since sludge is produced during the reaction of nitrifying bacteria with oxygen, it is difficult to separate and recycle the sludge and wastewater during the use of existing wastewater denitrification equipment. This easily leads to sludge being mixed in the treated wastewater, affecting the quality of wastewater recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a total nitrogen detection and treatment device for pesticide production wastewater, to solve the problems mentioned in the background art: 1. In some existing pesticide production wastewater denitrification processes, it is difficult to ensure uniform oxygen distribution inside the treatment tank; 2.

[0012] The outer ring of the support ring is equidistantly connected to four aeration components along the circumference. The bottoms of the four aeration components are movably connected to the interiors of the four arc-shaped grooves. A cleaning brush ring that cooperates with the aeration components is fixedly sleeved on the outer ring of the support ring.

[0013] Preferably, the aeration assembly includes seven aeration heads, which are equidistantly distributed in an arc shape on the side wall of the support ring. A telescopic air pipe is fixedly connected between two adjacent aeration heads, and a guide pin is fixedly connected to the bottom of the middle aeration head. The guide pin is slidably connected inside the corresponding arc groove.

[0014] Spring telescopic tubes are fixedly connected to the side walls of the aeration heads at both ends, and one end of the spring telescopic tube is fixedly connected to the side wall of the support ring.

[0015] Preferably, there are six wedge-shaped limiting blocks, which are fixedly connected at equal intervals along the circumference to the middle position of the outer wall of the limiting ring, and the number of limiting spring rods is the same as the number of wedge-shaped limiting blocks;

[0016] The inner ring of the support ring and the outer ring of the limiting ring are symmetrically and fixedly connected with sealed bearings.

[0017] Preferably, the sidewall of the drive shaft is symmetrically provided with rectangular grooves, and the opposite ends of the two adjusting pins are slidably connected inside the two rectangular grooves. The length of the rectangular groove is set to 1.2 times the height of the spiral groove, and the bottom of the rectangular groove is set as an inclined surface.

[0018] Preferably, the cleaning mechanism includes a cross-shaped cleaning frame, which is rotatably connected to the lower end of the drive shaft, and a torsion spring is fixedly connected between the bottom of the cross-shaped cleaning frame and the inner bottom surface of the treatment tank.

[0019] The top of the cross-shaped cleaning frame is fixedly connected with four pressure rods at equal intervals along the circumference. The top of the pressure rods overlaps with the surface of the corresponding inclined groove. The bottom surface of the treatment tank is provided with a sludge collection groove that cooperates with the cross-shaped cleaning frame.

[0020] Preferably, there are four sludge collection troughs, each corresponding to one of the four sides of the cross-shaped cleaning frame, and a collection box that matches the sludge collection trough is detachably installed at the bottom of the treatment tank.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] In this invention, through the coordinated use of components such as the drive shaft, regulating cylinder, and aeration regulating mechanism, when the nitrifying bacteria inside the treatment tank need to react with oxygen, the aeration mechanism enables the aeration components to rise, unfold, and rotate inside the treatment tank, promoting the uniform dispersion of oxygen inside the treatment tank, thereby improving the denitrification effect.

[0026] In this invention, through the coordinated use of components such as the drive shaft, aeration adjustment mechanism, and cleaning mechanism, when the cross-shaped support on the aeration adjustment mechanism moves downward, the sludge inside the treatment tank begins to settle, and the inclined groove at the bottom of the cross-shaped support contacts the top of the cleaning mechanism. When the cross-shaped support moves upward again, it drives the cross-shaped cleaning frame on the cleaning mechanism to rotate, automatically scraping the sludge inside the treatment tank into the sludge collection tank, thus separating the wastewater from the sludge and improving the quality of wastewater recycling.

[0027] In this invention, by using components such as the aeration head, the spring telescopic tube, and the cleaning brush ring in combination, the cleaning brush ring can clean the surface of the aeration head while the spring telescopic tube is retracting the aeration head, thus preventing sludge from adhering to the surface of the aeration head.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1 to 16 This invention provides a technical solution: a total nitrogen detection and treatment device for pesticide production wastewater, comprising:

[0047] The treatment tank 1 has a drive motor 2 fixedly connected to the middle of its top, and a transmission shaft 3 fixedly connected to the rotating end of the drive motor 2. An adjusting cylinder 4 that cooperates with the transmission shaft 3 is fixedly connected to the inner top surface of the treatment tank 1. It should be noted that the rotating end of the drive motor 2 extends into the interior of the treatment tank 1 and is fixedly connected to the top of the transmission shaft 3, while the adjusting cylinder 4 is movably sleeved on the outside of the transmission shaft 3.

[0048] Also includes:

[0049] The aeration regulating mechanism 5 is movably installed between the surface of the regulating cylinder 4 and the surface of the drive shaft 3. The drive shaft 3 drives the aeration regulating mechanism 5 to operate and distribute oxygen evenly inside the treatment tank 1.

[0050] A cleaning mechanism 6 is movably connected between the bottom of the treatment tank 1 and the bottom of the drive shaft 3. After the aeration regulating mechanism 5 moves down, it drives the cleaning mechanism 6 to clean the sludge.

[0051] In this embodiment, as Figures 1 to 16As shown, the aeration regulating mechanism 5 includes two spiral grooves 501, symmetrically arranged on the surface of the regulating cylinder 4. An regulating pin 502 is slidably connected inside each of the two spiral grooves 501. One end of the regulating pin 502 is slidably connected to the side wall of the drive shaft 3. A one-way bearing 503 is movably sleeved on the outside of the regulating cylinder 4. The other end of the regulating pin 502 is fixedly connected to the inner wall of the one-way bearing 503. A cross-shaped bracket 504 is fixedly sleeved on the outer ring of the one-way bearing 503. It should be noted that when the drive shaft 3 rotates with the drive motor 2, because the regulating pin 502 slides vertically on the side wall of the drive shaft 3, the rotation of the drive shaft 3 causes the regulating pin 502 to slide along the trajectory of the spiral groove 501, causing the regulating pin 502, along with the one-way bearing 503 and the cross-shaped bracket 504, to slowly rotate and rise.

[0052] The cross-shaped bracket 504 has arc-shaped grooves 505 on all four sides, and the bottom of the cross-shaped bracket 504 has a sloping groove 506 that cooperates with the cleaning mechanism 6.

[0053] A support ring 507 is rotatably connected to the top of the cross-shaped bracket 504. A limit ring 508 is rotatably connected to the inner ring of the support ring 507. A wedge-shaped limit block 509 is fixedly connected to the outer ring of the limit ring 508. A limit spring rod 510 that cooperates with the wedge-shaped limit block 509 is fixedly connected to the middle of the inner ring of the support ring 507. A Y-shaped gas transmission telescopic pipe 511 is fixedly connected to the top of the treatment tank 1. The two ends of the bottom of the Y-shaped gas transmission telescopic pipe 511 are symmetrically fixedly connected to the top of the limit ring 508. It should be noted that a positioning bearing is fixedly connected between the bottom of the support ring 507 and the top of the cross-shaped bracket 504 to ensure that the support ring 507 moves synchronously with the cross-shaped bracket 504 during its up-and-down movement. Under the constraint of the limiting spring rod 510 and the wedge-shaped limiting block 509, the frictional resistance of the support ring 507 is increased. Only after the rotational force of the cross-shaped bracket 504 overcomes the frictional resistance of the support ring 507 will the support ring 507 rotate synchronously with the cross-shaped bracket 504.

[0054] Four aeration components 512 are equidistantly connected to the outer ring of the support ring 507. The bottoms of the four aeration components 512 are movably connected to the interiors of four arc-shaped grooves 505. A cleaning brush ring 513 that mates with the aeration components 512 is fixedly fitted onto the outer ring of the support ring 507. It should be noted that the top of the Y-shaped air supply telescopic pipe 511 is connected to an air supply pump, allowing oxygen to be delivered from the Y-shaped air supply telescopic pipe 511 to the interiors of the four aeration components 512 for aeration. This air supply method is existing technology and will not be described in detail here. When the cross-shaped bracket 504 slides with the arc-shaped grooves 505 in conjunction with the aeration components 512, the aeration components 512 can unfold. During the retraction of the aeration components 512, the cleaning brush ring 513 can clean the top of the aeration components 512.

[0055] In this embodiment, as Figures 1 to 16 As shown, the aeration assembly 512 includes seven aeration heads 5121, which are equidistantly distributed in an arc shape on the side wall of the support ring 507. A telescopic air pipe 5122 is fixedly connected between adjacent aeration heads 5121. A guide pin 5123 is fixedly connected to the bottom of the middle aeration head 5121, and the guide pin 5123 is slidably connected inside the corresponding arc-shaped groove 505. It should be noted that the telescopic air pipe 5122 is an arc-shaped telescopic pipe, allowing the oxygen inside the seven aeration heads 5121 to be connected. When the Y-shaped air supply telescopic pipe 511 supplies oxygen into the support ring 507, the oxygen enters the corresponding aeration head 5121 from the spring telescopic pipe 5124. Under the action of the telescopic air pipe 5122, all seven aeration heads 5121 can perform aeration operations.

[0056] Both ends of the aeration head 5121 are fixedly connected to the sidewalls of spring telescopic tubes 5124, one end of which is fixedly connected to the sidewall of the support ring sleeve 507. It should be noted that both the spring telescopic tube 5124 and the Y-type air-transmitting telescopic tube 511 are multi-stage telescopic tubes, and the spring telescopic tube 5124 is normally in a retracted state. During the rotation of the cross-shaped support 504, due to the high frictional resistance between the support ring sleeve 507 and the limiting ring 508, the cross-shaped support 504 cannot rotate with the guide pin 5123, aeration head 5121, spring telescopic tube 5124, and support ring sleeve 507 via the arc groove 505. The telescopic tube 5124 can extend and retract, which causes the guide pin 5123 to move along the arc groove 505 and pull the aeration head 5121 to move towards the inner wall of the treatment tank 1, so that the seven aeration heads 5121 spread out in an arc shape. When the guide pin 5123 slides to the limit position in cooperation with the arc groove 505, as the cross-shaped bracket 504 continues to rotate, the support ring 507 overcomes the frictional resistance and rotates synchronously with the cross-shaped bracket 504, ensuring that oxygen is evenly dispersed inside the treatment tank 1.

[0057] In this embodiment, as Figures 1 to 16 As shown, six wedge-shaped limiting blocks 509 are fixedly connected at equal intervals along the circumference to the middle position of the outer wall of the limiting ring 508. The number of limiting spring rods 510 is the same as that of the wedge-shaped limiting blocks 509. It should be noted that when the limiting spring rod 510 contacts the inclined surface of the wedge-shaped limiting block 509, it can effectively increase the frictional resistance between the support ring sleeve 507 and the limiting ring 508.

[0058] A sealed bearing is symmetrically and fixedly connected between the inner ring of the support ring 507 and the outer ring of the limiting ring 508. It should be noted that the sealed bearing is designed to ensure the sealing between the inside of the support ring 507 and the limiting ring 508, so that the oxygen delivered by the Y-type gas delivery telescopic tube 511 can effectively enter the interior of the spring telescopic tube 5124.

[0059] In this embodiment, as Figures 1 to 16 As shown, the drive shaft 3 has symmetrical rectangular grooves on its sidewalls. The opposite ends of two adjusting pins 502 are slidably connected inside the two rectangular grooves. The length of the rectangular groove is 1.2 times the height of the spiral groove 501, and the bottom of the rectangular groove is sloped. It should be noted that the rectangular grooves allow the drive shaft 3 to rotate synchronously with the adjusting pins 502. As the adjusting pins 502 rotate along the spiral groove 501, they also slide up and down inside the rectangular groove. Under the action of the one-way bearing 503, when the adjusting pins 502 rotate upwards, they can rotate and rise along with the cross-shaped support 504. When the adjusting pins 502 rotate downwards, the one-way bearing 503 does not rotate the cross-shaped support 504, but it does move the cross-shaped support 504 downwards. This prevents the rotation of the cross-shaped support 504 during downward movement from causing severe disturbance to the sludge deposited inside the treatment tank 1, thus improving sludge collection efficiency. The sloped bottom of the rectangular grooves reduces the occurrence of residual sludge.

[0060] In this embodiment, as Figures 1 to 16 As shown, the cleaning mechanism 6 includes a cross-shaped cleaning frame 601, which is rotatably connected to the lower end of the drive shaft 3. A torsion spring 602 is fixedly connected between the bottom of the cross-shaped cleaning frame 601 and the inner bottom surface of the treatment tank 1. It should be noted that a mounting bearing is fixedly connected between the surface of the drive shaft and the inner ring of the cross-shaped cleaning frame to prevent the drive shaft from rotating the cross-shaped cleaning frame.

[0061] Four pressure rods 603 are fixedly connected at equal intervals along the circumference of the top of the cross-shaped cleaning frame 601. The top of the pressure rods 603 overlaps with the surface of the corresponding inclined groove 506. A sludge collection trough 604 that cooperates with the cross-shaped cleaning frame 601 is opened on the inner bottom surface of the treatment tank 1. It should be noted that during the downward movement of the cross-shaped support 504, under the constraint of the one-way bearing 503, the cross-shaped support 504 cannot rotate. At this time, the downward-moving cross-shaped support 504, along with the bottom inclined groove 506, presses against the top position of the pressure rod 603, causing the pressure rod 603 to rotate with the cross-shaped cleaning frame 601 at the bottom of the treatment tank 1. This causes the pressure rod 603 to move to the extreme position of the side wall of the inclined groove 506. When the adjusting pin 502 and the one-way bearing 503 rotate the cross-shaped support 504 counterclockwise again and slowly rise, the inclined groove 506 at the bottom of the cross-shaped support 504 will rotate synchronously with the pressure rod 603 and the cross-shaped cleaning frame 601 and gradually disengage from the contact state with the pressure rod 603. At this time, the cross-shaped cleaning frame 601 can push the sludge deposited at the bottom of the treatment tank 1 into the interior of the sludge collection tank 604, separating the sludge from the wastewater and ensuring the quality of wastewater recovery.

[0062] In this embodiment, as Figures 1 to 16 As shown, there are four sludge collection tanks 604, which correspond one-to-one with the four sides of the cross-shaped cleaning rack 601. The bottom of the treatment tank 1 is detachably equipped with a collection box that matches the sludge collection tank 604.

[0063] A connecting bearing is fixedly connected between the bottom of the cross-shaped cleaning frame 601 and the inner bottom surface of the treatment tank 1, and a torsion spring 602 is located in the inner ring of the connecting bearing. It should be noted that the connecting bearing is a sealed bearing type. This design prevents wastewater from entering the position of the torsion spring 602. Furthermore, matching positioning blocks are provided between the bottom of the treatment tank 1 and the bottom of the cross-shaped cleaning frame 601, allowing the torsion spring 602 to rotate the cross-shaped cleaning frame 601 back to its initial position.

[0064] In this embodiment, as Figures 1 to 16 As shown, an infusion pipe is installed at the top of treatment tank 1, and a drain pipe is fixedly connected to the lower side wall of treatment tank 1. It should be noted that a nitrifying bacteria inlet is also provided at the top of treatment tank 1.

[0065] A pH detector is fixedly connected to the outer wall of treatment tank 1. It should be noted that the pH detector is used to monitor the treated wastewater. This pH detector is existing technology and will not be described in detail here.

[0066] The method of use and advantages of this invention: The working process of this pesticide production wastewater total nitrogen detection and treatment equipment is as follows:

[0067] like Figures 1 to 16As shown, during use, oxygen is first delivered between the support ring 507 and the limiting ring 508 through the Y-shaped gas delivery telescopic pipe 511, so that oxygen enters the interior of the aeration head 5121 and the telescopic air pipe 5122 from the spring telescopic pipe 5124. At this time, the aeration head 5121 delivers oxygen to the interior of the treatment tank 1. Then, the drive motor 2 is started to drive the transmission shaft 3 to rotate counterclockwise at low speed. During this process, the transmission shaft 3 carries two adjusting pins 502 to slide along the corresponding spiral groove 501 trajectory, so that the rotating adjusting pins 502 carry the one-way bearing 503 and the cross-shaped bracket 504 to slowly rotate and rise along the surface of the adjusting cylinder 4.

[0068] During this process, the aeration head 5121 is restricted to the side wall position of the support ring sleeve 507 by the spring telescopic tube 5124, and the limiting spring rod 510 on the support ring sleeve 507 cooperates with the wedge-shaped limiting block 509 on the surface of the limiting ring 508 to limit the aeration head 5121, preventing it from rotating synchronously with the cross-shaped bracket 504. Meanwhile, the arc-shaped groove 505 on the cross-shaped bracket 504 cooperates with the guide pin 5123 at the bottom of the aeration head 5121 to slide, causing the guide pin 5123 to move the aeration head 5121 towards the inner wall of the treatment tank 1, thus extending the spring telescopic tube 5124. Then, the aeration heads 5121... The telescopic air pipe 5122 extends, causing the seven arc-shaped aeration heads 5121 to unfold in an arc shape inside the treatment tank 1. When the adjusting pin 502 slides to its limit position inside the arc-shaped groove 505, the force of the cross-shaped support 504 rotating the aeration heads 5121 through the adjusting pin 502 will overcome the frictional force of the limiting spring rod 510 and the wedge-shaped limiting block 509. This causes the support ring sleeve 507, the spring telescopic pipe 5124, and the aeration heads 5121 to slowly rise with the rotation of the cross-shaped support 504, distributing oxygen evenly inside the treatment tank 1, allowing the nitrifying bacteria in the wastewater inside the treatment tank 1 to fully react with oxygen.

[0069] When the cross-shaped support 504, carrying the aeration head 5121, rises to its limit position, the oxygen supply of the Y-shaped air supply telescopic pipe 511 is closed, and the drive motor 2 is started to rotate in the reverse direction. At this time, the adjusting pin 502 and the spiral groove 501 on the adjusting cylinder 4 slide in the opposite direction, and the adjusting pin 502 carries the cross-shaped support 504 to slowly move down. Under the action of the one-way bearing 503, the one-way bearing 503, which is rotating in the reverse direction, will not carry the cross-shaped support 504 to rotate in the opposite direction, and the cross-shaped support 504, which has stopped rotating, will not carry the adjusting pin 502 and the aeration head 5121 to continue to rotate. At this time, the spring telescopic tube 5124 recovers its elasticity and moves the aeration head 5121 and the adjusting pin 502 to reset inside the arc groove 505. When the seven aeration heads 5121 move towards the adjusting cylinder 4, the telescopic air tube 5122 between the seven aeration heads 5121 contracts, causing the seven aeration heads 5121 to close together. During this process, the support ring 507 will also reverse at the top of the cross-shaped bracket 504, and the reversal of the limiting spring rod 510 will also release the contact with the wedge-shaped limiting block 509, ensuring that the seven aeration heads 5121 can stably move towards the adjusting cylinder 4.

[0070] When the seven aeration heads 5121 retract, the sludge inside the treatment tank 1 begins to settle. As the cross-shaped support 504 descends to its limit position, the inclined groove 506 at the bottom of the cross-shaped support 504 engages with the pressure rod 603 at the top of the cross-shaped cleaning frame 601, causing the pressure rod to engage inside the inclined groove. As the adjusting pin 502 and the one-way bearing 503 rotate counterclockwise and slowly rise again, the sludge has finished settling. The inclined groove 506 at the bottom of the cross-shaped support 504 will rotate synchronously with the pressure rod 603 and the cross-shaped cleaning frame 601, gradually disengaging from the pressure rod 603. This causes the pressure rod 603 to rotate with the cross-shaped cleaning frame 601 on the inner bottom surface of the treatment tank 1, pushing the settled sludge into the collection tank 604, separating the sludge from the treated wastewater. After repeating the above steps multiple times, the oxygen fully reacts with the nitrifying bacteria, thus achieving the denitrification effect of pesticide wastewater.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
