Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device and a treatment method. Background Art

[0002] Treating wastewater with flocculants is a common and effective method in modern water treatment technology. Flocculants, such as inorganic salts and organic polymers, can quickly undergo physical and chemical reactions such as adsorption, neutralization, and bridging with suspended particles and colloids in wastewater through their special chemical structure or charged properties, causing these tiny, difficult-to-sediment pollutant particles to condense into larger floccules, thereby facilitating subsequent treatment steps such as precipitation and filtration. This treatment method can significantly improve the clarity of wastewater, reduce suspended matter and turbidity, and provide a good foundation for subsequent water purification.

[0003] However, despite the many advantages of using flocculants to treat wastewater, existing treatment devices still have some shortcomings in practical applications. First, due to the design of the device or the mode of operation, the flocculant is often unable to be fully and evenly dispersed in the wastewater. This results in the flocculant being unable to fully contact and react with the pollutants in the wastewater, thereby affecting the effect of wastewater treatment. Some pollutants may remain in the water because they do not react with the flocculant, resulting in incomplete wastewater treatment. Secondly, since the flocculant is not fully dispersed, its dosage may increase, resulting in waste of reagents and rising costs. This not only increases the economic burden of the enterprise, but may also have a certain negative impact on the environment.

[0004] In addition, the existing flocculation solid-liquid treatment also has certain problems. Since the floccules formed after the flocculant combines with the pollutants are large in volume and high in density, it is difficult to completely remove them by simple filtration or sedimentation. If these residual flocculation solids and liquids are not properly handled, they may cause secondary pollution to the environment.

[0005] In summary, the difficulty in fully breaking up the flocculants and the inconvenience in separating the floccules are problems that need to be urgently solved in existing wastewater treatment devices. Summary of the invention

[0006] In order to overcome the above-mentioned disadvantages, the present invention provides a wastewater treatment device and a treatment method having a reagent stirring function and a sediment treatment function.

[0007] A wastewater treatment device comprises a treatment box, wherein the upper part of the treatment box is provided with an inlet pipe, the bottom part of the treatment box is provided with an outlet pipe, and the treatment box also comprises a chemical pipe, a multi-tube nozzle, a power source, a sedimentation tank, an opening and closing assembly, a sealing plate and a filter plate. The chemical pipe rotates and penetrates into the treatment box. The outside of the chemical pipe is connected with six evenly distributed multi-tube nozzles, and the multi-tube nozzle is equipped with eight radial nozzles. The power source drives the chemical pipe to rotate through gear transmission. Eight sedimentation tanks are arranged at the bottom of the inner cavity of the treatment box. The sedimentation tank is provided with a sealing plate connected by hinge rotation. The sealing plate can close the sedimentation tank. A lifting filter plate is arranged at the bottom of the sedimentation tank. Two screw rods are symmetrically arranged. The screw rods are rotatably connected in the treatment box. The power source supplies energy to the screw rod. The tooth block slides on the screw rod through a threaded limit. When the tooth block moves on the screw rod, the sealing plate and the filter plate are driven to open and close alternately through the opening and closing assembly, so that the sediment at the bottom of the treatment box falls into the sedimentation tank for filtration, and then the sediment is led out by the filter plate, so as to achieve the treatment effect of flocculent and solid-liquid separation of wastewater.

[0008] Preferably, the opening and closing assembly consists of a rotating seat, a threaded rod, a transmission gear c and a pull rod. The rotating seat is rotatably connected to the top surface of the processing box. The upper part of the rotating seat is connected to a transmission gear b that can engage with the gear block. The lower part of the rotating seat is a hollow cone and has a half gear ring inside. Two threaded rods are provided inside the rotating seat. The threaded rods are rotatably connected to the processing box. The upper end of the threaded rod is fixed with a transmission gear c. The lower end of the threaded rod is provided with a pull rod through a threaded sleeve. The pull rod is slidably connected to the processing box, and the ends of the pull rod are respectively connected to the sealing plate and the filter plate.

[0009] Preferably, the tooth length of the half gear ring is consistent with the circumference of the transmission gear c.

[0010] Preferably, the screw rod is provided with a closed reciprocating thread.

[0011] Preferably, it also includes an enhancement component that drives the multi-tube nozzle to rotate. The enhancement component consists of a transmission shaft and a bevel gear group. The transmission shaft is rotatably connected in the medicine tube. The transmission shaft transmits the multi-tube nozzle through the bevel gear group. The bevel gear group consists of two bevel gears that mesh with each other, one of which is connected to the transmission shaft, and the other is connected to the inner end of the multi-tube nozzle. The side of the processing box is rotatably connected with a transmission gear a, and the servo motor supplies energy to the transmission gear a through a transmission belt. A gear ring is provided at the end of the medicine tube, which meshes with the transmission gear a. A transmission gear d is fixedly connected to the end of the transmission shaft, and the transmission gear d meshes with the transmission gear a.

[0012] Preferably, a corrugated plate is further included, which is fixed to the inner wall of the treatment box, specifically located below the sedimentation tank. The corrugated plate can block and limit one side of the filter plate to push the filter plate to tilt so that the flocculants retained on the filter plate can be dumped.

[0013] Preferably, a guide plate is further included, which is fixedly connected to the bottom surface of the treatment box at an angle, with the end of the guide plate passing through the treatment box, and the middle of the guide plate is recessed inward to form a guide groove, so that the guide plate can dock with the filter plate.

[0014] According to the above-mentioned wastewater treatment equipment, a wastewater treatment method is now proposed, which is as follows:

[0015] S1, introduce wastewater into the treatment box through the water inlet pipe, pass the flocculant into the reagent pipe, and then turn on the power source;

[0016] S2, the power source drives the chemical tube and the transmission shaft to rotate continuously in the opposite direction, the multi-tube nozzle will rotate with the chemical tube, and at the same time, the transmission shaft drives the multi-tube nozzle to rotate through the bevel gear set, and the flocculant in the multi-tube nozzle will be evenly dispersed into the wastewater;

[0017] S3, after the flocculant is fully mixed with the wastewater, it forms flocs with the impurities and settles in the sedimentation tank, and the flocs and wastewater are filtered through the filter plate;

[0018] S4, the sealing plate and the filter plate are driven to open and close alternately through the opening and closing assembly. When the sealing plate is opened and the filter plate is closed, the wastewater is separated into solid and liquid through the filter plate. When the sealing plate is closed and the filter plate is opened, the filter plate moves downward and tilts under the blocking limit of the corrugated plate to dump the flocs. The flocs are guided out by the guide plate to realize solid-liquid separation.

[0019] The beneficial effects of the present invention are as follows: the multi-tube nozzle is driven to rotate by the chemical tube, and at the same time, the transmission shaft drives the multi-tube nozzle to rotate, and the flocculant is uniformly dispersed into the wastewater through the multi-tube nozzle, and the flocculant will be fully mixed with the wastewater, thereby improving the flocculation reaction while reducing the waste of chemical agents, and improving the treatment effect of the wastewater. The flocculent is deposited in the sedimentation tank with the wastewater, and the sealing plate and the filter plate are driven to open and close alternately by the opening and closing component, so that the wastewater can be filtered through the filter plate, and the filter plate can intermittently move downward to dump and clean the flocculent, which not only achieves the filtering effect of the wastewater, but also completes the solid-liquid separation treatment after the flocculation reaction, and further improves the treatment effect of the wastewater.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment: A wastewater treatment device, such as Figure 1-Figure 7 As shown, it includes a treatment box 1, a water inlet pipe 101 is provided on the upper part of the treatment box 1, a water outlet pipe 102 is provided at the bottom of the treatment box 1, and also includes a chemical tube 2, a multi-tube nozzle 3, a power source, a sedimentation tank 5, an opening and closing component 8, a sealing plate 9 and a filter plate 10. The chemical tube 2 rotates and penetrates into the treatment box 1. The outside of the chemical tube 2 is connected to the evenly distributed multi-tube nozzle 3. The power source drives the chemical tube 2 to rotate through a gear transmission. The power source is a servo motor 4. The bottom of the inner cavity of the treatment box 1 is provided with eight independent space sedimentation tanks 5. The sedimentation tank 5 is provided with a sealing plate 9 rotatably connected by a hinge. The sealing plate 9 can The sedimentation tank 5 can be closed, and a lifting filter plate 10 is arranged at the bottom of the sedimentation tank 5. Two screw rods 6 are symmetrically arranged, and the screw rods 6 are rotatably connected in the treatment box 1. A closed reciprocating thread is opened on the screw rod 6. The servo motor 4 drives the screw rod 6 through the pulley group, and the gear block 7 slides on the screw rod 6 through the thread limit. When the gear block 7 moves on the screw rod 6, the sealing plate 9 and the filter plate 10 are driven to open and close alternately through the opening and closing assembly 8, so that the sediment at the bottom of the treatment box 1 falls into the sedimentation tank 5 for filtration, and then the sediment is discharged by the filter plate 10, so as to achieve the treatment effect of flocculent and solid-liquid separation of wastewater.

[0031] like Figure 5 and Figure 6 As shown, the opening and closing assembly 8 is composed of a rotating seat 11, a threaded rod 12, a transmission gear c1201 and a pull rod 13. The rotating seat 11 is rotatably connected to the top surface of the processing box 1. The upper part of the rotating seat 11 is connected to a transmission gear b1101 that can mesh with the gear block 7. The lower part of the rotating seat 11 is a hollow cone and has a half gear ring 1102 inside. Two threaded rods 12 are arranged inside the rotating seat 11. The two threaded rods 12 are rotatably connected to the inner side of the processing box 1 through a connecting rod. The upper end of the threaded rod 12 is fixedly connected to the transmission gear c1201. The tooth length of the half gear ring 1102 is consistent with the circumference of the transmission gear c1201. The lower end of the threaded rod 12 is provided with a pull rod 13 through a threaded sleeve. The pull rod 13 is slidably connected to the processing box 1 through a connecting rod. On the inner side, the ends of the pull rod 13 are respectively connected to the sealing plate 9 and the filter plate 10. In this embodiment, in order to improve the opening and closing effect of the sealing plate 9, the sealing plate 9 is set to a two-way opening and closing structure with a middle hinge connection. Therefore, one of the pull rods 13 and the sealing plate 9 will be connected through a hinge seat and a sliding rod to provide space for the sealing plate 9 to rotate and open and close. Specifically, the lower end of the pull rod 13 is fixed with a transverse sliding rod, and the sealing plate 9 is provided with a hinge seat, which is slidably sleeved in the sliding rod. When the pull rod 13 drives the sealing plate 9 to rotate and open and close, the hinge seat rotates accordingly, and the lower end of the other pull rod 13 is rotatably connected to the middle of the filter plate 10 and a torsion spring is connected between the two. The pull rod 13 can drive the filter plate 10 to move up and down.

[0032] Recommended reference Figure 4 The servo motor 4 drives the screw 6 to rotate continuously through the pulley group. Since the tooth block 7 is limited and slides on the top surface of the processing box 1, the tooth block 7 moves back and forth in the horizontal direction under the action of the screw 6. During this period, the tooth block 7 can contact and drive the transmission gear b1101 to rotate unidirectionally. The tooth block 7 moves to the left and drives the transmission gear b1101 to rotate to the right, thereby driving the rotating seat 11 to rotate to the right. The semi-gear ring 1102 at the bottom of the rotating seat 11 will contact and drive the transmission gear c1201 to rotate in turn, and then the transmission gear c1201 will drive the threaded rod 12 to rotate, and the threaded rod 12 will drive the pull rod 13 to pull the sealing plate 9 and the filter plate 10 in turn. It is worth noting that the sealing plate 9 and the filter plate 10 always maintain any open state. For example, when the sealing plate 9 is opened, the filter plate 10 is closed. At this time, the wastewater in the treatment box 1 continues to enter the sedimentation tank 5 and is separated into solid and liquid by the filter plate 10, and when the sealing plate 9 is closed, the filter plate 10 moves downward and opens. At this time, the flocculants retained in the filter plate 10 are cleaned. Based on the above principles, when the tooth block 7 moves to the left, the sealing plate 9 is opened and the filter plate 10 is closed by the pull rod 13. When the tooth block 7 moves to the right, the sealing plate 9 is closed and the filter plate 10 is opened by the pull rod 13, thereby realizing the filtration of the wastewater and the intermittent cleaning of the flocculants, and achieving the solid-liquid separation treatment effect.

[0033] like Figure 2 and Figure 3As shown, in this embodiment, six multi-tube nozzles 3 are provided, and each multi-tube nozzle 3 is provided with eight radial nozzles.

[0034] like Figure 7 As shown, it also includes a synergistic component that drives the multi-tube nozzle 3 to rotate. The synergistic component consists of a transmission shaft 14 and a bevel gear set 15. The transmission shaft 14 is rotatably connected in the medicine tube 2. The transmission shaft 14 transmits the multi-tube nozzle 3 through the bevel gear set 15. The bevel gear set 15 consists of two bevel gears that mesh with each other, one of which is connected to the transmission shaft 14, and the other is connected to the inner end of the multi-tube nozzle 3. The side of the processing box 1 is rotatably connected to a transmission gear a401 through a bracket, and the servo motor 4 supplies energy to the transmission gear a401 through a transmission belt. A gear ring is provided at the end of the medicine tube 2, and the gear ring is meshed with the transmission gear a401. The end of the transmission shaft 14 is fixedly connected to a transmission gear d14 01, the transmission gear d1401 is meshed with the transmission gear a401, so the ring gear, the transmission gear a401 and the transmission gear d1401 form a planetary gear set, that is, the transmission gear a401 drives the ring gear and the transmission gear d1401 to rotate at the same time, and the rotation directions of the ring gear and the transmission gear d1401 are different, that is, when the chemical tube 2 rotates, the transmission shaft 14 rotates in the opposite direction, so the multi-tube nozzle 3 can rotate while revolving with the chemical tube 2, the effect is that the flocculant can not only be evenly extracted from the multi-tube nozzle 3 and fully dispersed into the wastewater, but also the multi-tube nozzle 3 can provide a stirring function, further improving the contact reaction between the flocculant and the wastewater, and improving the treatment effect on the wastewater.

[0035] like Figure 8 As shown, a corrugated plate 16 is also included. The corrugated plate 16 is fixedly connected to the inner wall of the treatment box 1, specifically located below the sedimentation tank 5. The corrugated plate 16 can block and limit one side of the filter plate 10 to push the filter plate 10 to tilt, so that the flocs retained on the filter plate 10 can be dumped. When the side of the filter plate 10 passes through the corrugated plate 16, it shakes and can shake off the flocs.

[0036] like Figure 2 As shown, it also includes a guide plate 17, which is tilted and fixed to the bottom surface of the treatment box 1, and the end of the guide plate 17 passes through the treatment box 1, and the middle of the guide plate 17 is recessed inward to form a guide groove. The guide plate 17 can dock with the filter plate 10, that is, the pull rod 13 pushes the filter plate 10 to move downward, and then one side of the filter plate 10 is blocked and limited by the corrugated plate 16 to tilt, and the flocculants fall into the guide plate 17 from one side of the filter plate 10. Because the guide plate 17 is tilted toward the front end, the flocculants falling into the guide plate 17 will be discharged in an orderly manner, and the staff can carry out unified processing.

[0037] According to the above-mentioned wastewater treatment equipment, a wastewater treatment method is now proposed, which is as follows:

[0038] S1, wastewater is introduced into the treatment box 1 through the water inlet pipe 101, flocculant is introduced into the reagent pipe 2, and then the servo motor 4 is turned on;

[0039] S2, the servo motor 4 drives the reagent tube 2 and the transmission shaft 14 to continuously rotate in the opposite direction, and the multi-tube nozzle 3 will rotate along with the reagent tube 2. At the same time, the transmission shaft 14 drives the multi-tube nozzle 3 to rotate by itself through the bevel gear set 15, and the flocculant in the multi-tube nozzle 3 will be evenly dispersed into the wastewater;

[0040] S3, after the flocculant is fully mixed with the wastewater, it forms flocs with the impurities and settles in the sedimentation tank 5, and the flocs and wastewater are filtered through the filter plate 10;

[0041] S4, the sealing plate 9 and the filter plate 10 are driven to open and close alternately through the opening and closing component 8. When the sealing plate 9 is opened and the filter plate 10 is closed, the wastewater is separated into solid and liquid through the filter plate 10. When the sealing plate 9 is closed and the filter plate 10 is opened, the filter plate 10 moves downward and tilts under the blocking limit of the corrugated plate 16 to dump the flocs. The flocs are guided out by the guide plate 17 to realize solid-liquid separation.

[0042] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
