Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and specifically to a wastewater treatment device and a wastewater treatment method. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. There are many methods for treating wastewater, which can be summarized as physical methods, chemical methods, and biological methods. Currently, wastewater treatment generally uses physical methods to filter and screen solid impurities in the wastewater, followed by precipitation reactions using chemical reagents. Most existing wastewater treatment devices use filter cartridges or membranes to filter sludge from wastewater. During sludge discharge, the sludge easily clogs the filter mesh, blocking the entire channel, requiring regular manual dredging. Application number CN202310363143.8 discloses a sludge discharge device for wastewater treatment with anti-clogging properties, including a sedimentation tank, a screening device, and a sludge conveying device. The screening device is located on one side of the sedimentation tank, and the sludge conveying device is located below the sedimentation tank. The sedimentation tank has an outlet and an outlet gate assembly on the side corresponding to the screening device. The screening device includes a screening box, a screen, and a brush wheel assembly. Each brush plate has closely arranged brushes. A second guide plate and the set of sludge gate assemblies are located below the sedimentation tank. This device can efficiently filter sewage and ensure that the screen structure does not get clogged; however, the brush wheel assembly is a one-way brushing device for the screen. Although it can remove sludge from one side of the screen, the sludge on the other side cannot be removed. After the screen has been used for a long time, the sludge on the other side of the screen will accumulate and clog the screen, affecting the use of the screen and thus affecting the efficiency of sewage treatment. Therefore, a sewage treatment device and sewage treatment method are proposed. Summary of the Invention

Wastewater is transported through an inlet pipe to a filter screen formed by the intersection of first ropes. The filter screen intercepts sludge in the wastewater.

[0028] 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.

[0029] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and the simplified description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed in a specific orientation, or be operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0030] In the description of this specification, references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] In this application, a fixed connection refers to a connection where, after the parts or components are installed, there is no relative movement. Common examples include using screws, splines, wedges, etc., to fix parts together. This type of connection allows for disassembly during maintenance without damaging the parts. Other methods include welding, riveting, and tenon joints. These methods require forging, sawing, or oxy-acetylene cutting for disassembly during maintenance or replacement, so the parts are generally not reusable. A rotating connection, in this application, is a connection where, after the parts or components are installed, the parts rotate relative to the fixed part. A common form is a relationship where a bearing is mounted on the fixed part, with the part mounted on the inner or outer ring of the bearing, allowing the bearing to achieve rotational movement. A sliding connection, in this application, is a connection where, after the parts or components are installed, the parts can move on the fixed part.

[0032] A wastewater treatment device includes: a separation tank 1 and a purification tank 2; the purification tank 2 is connected to the separation tank 1 via a transfer pump 3 and a pipeline 4; the purification tank 2 is equipped with a stirring mechanism inside; the separation tank 1 first filters the wastewater, and the filtered wastewater is transported to the purification tank 2 via the pipeline 4 and the transfer pump 3; chemical reagents are introduced into the purification tank 2, and the chemical reagents and wastewater are fully mixed and reacted by the stirring mechanism to complete the purification of the wastewater; finally, the wastewater is discharged from the purification tank 2.

[0033] The separation box 1 is symmetrically and fixedly installed with two parallel first supports 5; the separation box 1 is symmetrically and fixedly installed with two parallel second supports 6; the second supports 6 and the first supports 5 are arranged perpendicularly; one first support 5 and the second support 6 are both provided with a first sliding groove, and the other first support 5 and the second support 6 are both provided with a second sliding groove; the first sliding groove is linearly and evenly slidably connected to a first movable seat 7; the second sliding groove is linearly and evenly slidably connected to a second movable seat 8; therefore, the two movable seats can move along the sliding groove; the first movable seat 7 and the second movable seat 8 are both rotatably connected to a movable shaft 9; the movable shaft 9 of the first movable seat 7 is connected to the movable shaft 9 of one of the second movable seats 8 through a first rope 10; since the first support 5 and the second support 6 are arranged perpendicularly, the first rope 10 on the first support 5 and the first rope 10 on the second support 6 intersect perpendicularly to form a filter screen;

[0034] A first fixed seat 11 is fixedly installed in the first slide groove; a second fixed seat 12 is fixedly installed in the second slide groove; the first fixed seat 11 and a second fixed seat 12 are also fixedly connected by a first rope 10; the first movable seat 7 and the first fixed seat 11 are both fixedly connected by a second rope 13; the second movable seat 8 and the second fixed seat 12 are also fixedly connected by a second rope 13; both the second bracket 6 and the first bracket 5 are provided with two mounting slots; a first motor 14 and a second motor 15 are fixedly installed in the mounting slots respectively; the first motor 14 is installed with a first screw 66 in the first slide groove; the first screw 66 is threadedly connected to the first movable seat 7 near the first motor 14; the second motor 15 is installed with a second screw 67 in the second slide groove; the second screw 67 is threadedly connected to the second movable seat 8 near the second motor 15.

[0035] When the first motor 14 drives the first screw 66 to rotate, the first screw 66 drives the first movable seat 7 to move along the first slide groove via a thread. When the first movable seat 7 moves toward the first fixed seat 11, the first movable seat 7 pushes the other first movable seats 7 to move sequentially until they abut against the first fixed seat 11. During reset, the first movable seat 7 threadedly connected to the first screw 66 pulls the other first movable seats 7 to move via the second rope 13 until it returns to its initial position. At the same time, when the second motor 15 drives the second screw 67 to rotate, it also drives the second movable seat 8 to move along the second slide groove, causing the other second movable seats 8 to move. The movement of the two movable seats means that the gap of the first ropes 10 used to construct the filter screen changes, and the mesh formed by the intersection of the first ropes 10 shrinks. As a result, the sludge lumps located in the mesh will fall off due to the change in the mesh size.

[0036] Both the first support 5 and the second support 6 are symmetrically provided with linearly movable blocks 68; each movable block 68 is fixedly mounted with a first spur rack 69; each movable shaft 9 is fixedly mounted with a first spur gear 43; the first spur gear 43 meshes with the first spur rack 69; when the movable block 68 drives the first spur rack 69 to move, it will drive the first spur gear 43 to rotate, and the first spur gear 43 will drive the movable shaft 9 and the first rope 10 to rotate. After the first rope 10 rotates, the edge part of the sludge block attached to the mesh breaks off from the center part, causing the sludge block to fall off; the first support 5 is provided with a linearly movable brush 16 at the upper end of the first rope 10; the separation box 1 is fixedly mounted with an inlet pipe 17 at the upper end of the first rope 10; the separation box 1 is provided with a linearly movable recycling box 18 at the lower end of the first rope 10.

[0037] The wastewater treatment method of this application includes the following steps:

[0038] First, the wastewater is fed into the separation tank 1 through the inlet pipe 17. The wastewater will first come into contact with the filter screen formed by the first rope 10. The filter screen intercepts sludge and solid impurities, and the wastewater enters the bottom of the separation tank 1. Then, the wastewater is transported to the purification tank 2 through the pipe 4 and the transfer pump 3. Chemical reagents are added to the purification tank 2, and the chemical reagents and wastewater are fully mixed and reacted by the stirring mechanism to complete the purification of the wastewater. Finally, the wastewater is discharged from the purification tank 2.

[0039] While the purification box 2 is processing the filter, the drive collection box 18 is moved to the bottom of the filter screen, and the brush 16 is moved to the top of the filter screen. The first motor 14 and the second motor 15 drive the first screw 66 and the second screw 67 to rotate, causing the first movable seat 7 and the second movable seat 8 to move. As a result, the mesh size of the first rope 10 changes. At the same time, the first spur gear 43 and the first straight gear 43 on the movable shaft 9 mesh and rotate. The first rope 10 rotates while changing the mesh size, causing the sludge in the mesh to fall into the collection box. Due to the obstruction of the brush 16, solid impurities on the filter screen are also swept into the collection box. Then, the drive brush 16 moves back and forth to clean the filter screen. The movable block 68 drives the first straight rack 69 to move, causing the first straight gear 43 to drive the movable shaft 9 and the first rope 10 to rotate, thereby cleaning each position on the first rope 10 and cleaning the first rope 10.

[0040] In this application, all linearly movable components can be implemented using linear drive mechanisms, such as hydraulic telescopic rods, electric telescopic rods, and pneumatic telescopic rods. Of course, other structures that can change the position of the connecting end can also be used, such as chain lifting mechanisms used in forklifts, scissor telescopic mechanisms used in scissor lifts, and screw lifting mechanisms in screw conveyors.

[0041] In some embodiments, the movable block 68 is slidably connected to the adjacent second bracket 6 or the first bracket 5; the separation box 1 is symmetrically rotatably connected to two parallel third screws 19 and two parallel fourth screws 20; both the third screws 19 and the fourth screws 20 are threadedly connected to an adjacent movable block 68; after the fourth screws 20 and the third screws 19 rotate, they drive the movable block 68 to move linearly along the first bracket 5 or the second bracket 6 through the threads;

[0042] Each of the third screws 19 is fixedly mounted with a first sprocket 21; the first sprocket 21 is connected by a chain, and the third screw 19 rotates synchronously through the first sprocket 21 and the chain; a connecting seat is fixedly mounted on the side of the separation box 1 near the third screw 19; a connecting shaft 22 is rotatably connected to the connecting seat; a first bevel gear 23 is fixedly mounted on the connecting shaft 22; a second bevel gear 24 is fixedly mounted on the third screw 19; the first bevel gear 23 meshes with the second bevel gear 24; each of the fourth screws 20 is fixedly mounted with a second sprocket 25; the second sprocket 25 is connected by a chain, and the fourth screw 20 rotates synchronously through the second sprocket 25 and the chain; a third sprocket 26 is fixedly mounted on the connecting shaft 22 and one of the fourth screws 20; the third sprocket 26 is connected by a chain; the connecting shaft 22 drives the fourth screw 20 to rotate through the third sprocket 26 and the chain, and the connecting shaft 22 drives the first screw 66 to rotate through the first bevel gear 23 and the second bevel gear 24;

[0043] A second spur gear 27 is fixedly mounted on the outside of the separation box 1 via the third screw 19, the fourth screw 20, or the connecting shaft 22; a drive seat, a transmission seat, and a third motor 37 are fixedly mounted on the side of the separation box 1 near the second spur gear 27; a drive shaft 28 is rotatably connected to the drive seat; a sector block 29 is fixedly mounted on the drive shaft 28; the sector block 29 has an arc surface; an arc-shaped slide rail is fixedly mounted on the arc surface; an arc-shaped rack 30 is slidably connected to the arc-shaped slide rail; the arc-shaped rack 30 meshes with the second spur gear 27; the sector block 29 is mounted on the arc-shaped rack 30. Push blocks 31 are fixedly installed on both sides of 0; a fan-shaped block 29 is provided with a strip hole 32; an adjusting seat slides on the strip hole 32; an adjusting shaft is fixedly installed on the adjusting seat; a nut 33 is threadedly connected to the adjusting shaft; the nut 33 abuts against the strip hole 32; a rocker arm 34 is rotatably connected to the adjusting shaft; a transmission shaft is rotatably connected to the transmission seat; a rocker arm 35 and a third bevel gear 36 are fixedly installed on the transmission shaft; a fourth bevel gear 38 is fixedly installed on the third motor 37; the third bevel gear 36 meshes with the fourth bevel gear 38; rocker arm 34 and rocker arm 35 are rotatably connected.

[0044] When the brush 16 cleans the first rope 10, the third motor 37 is started. The third motor 37 drives the transmission shaft to rotate through the third bevel gear 36 and the fourth bevel gear 38. The transmission shaft drives the first swing rod 34 to swing through the second swing rod 35, thereby driving the sector block 29 to swing. The sector block 29 pushes the arc rack 30 to rotate through the push block 31, thereby driving the second spur gear 27 to rotate. When the sector block 29 swings to the maximum angle and returns, the arc rack 30 is held by the second spur gear 27. The arc rack 30 does not move but slides along the arc track of the sector block 29 until another push block 31 holds the arc rack 30 and drives the arc rack 30 to rotate with the sector block 29. Therefore, the second spur gear 27 will cycle between forward rotation, stop, reverse rotation and stop, thereby driving the third screw 19, the fourth screw 20 and the connecting shaft 22 to rotate intermittently back and forth, so as to drive the drive block 68 to move linearly along the first bracket 5 or the second bracket 6.

[0045] During the cleaning process, the first rope 10 will continuously rotate up and down. Since the lower end of the filter screen formed by the first rope 10 is opposite to the cleaning surface of the brush 16, while the side of the first rope 10 can be scraped by the brush 16 during its movement, the contact time between the upper and lower ends of the first rope 10 and the brush 16 is longer than that between the sides during the movement of the brush 16, thus effectively cleaning the first rope 10.

[0046] In some embodiments, a fourth motor 39 is symmetrically fixedly installed on the separation box 1; a fifth screw 40 is installed on the upper end of the fourth motor 39 on the first bracket 5; the fifth screw 40 is threadedly connected to the cleaning seat 41; the cleaning seat 41 is provided with a groove 42; a cleaning shaft is rotatably connected inside the groove 42; a third spur gear 43 and a mounting rod 44 are fixedly installed on the cleaning shaft; a second spur rack 45 is fixedly installed on the first bracket 5 on the moving path of the third spur gear 43; the second spur rack 45 can mesh with the third spur gear 43; a brush 16 is fixedly installed on the mounting rod 44; two magnets are provided in the groove 42; one magnet is arranged horizontally and the other is arranged vertically; both magnets are attracted to the mounting rod 44.

[0047] Initially, due to the large contact area between the upper end face of the mounting rod 44 and the magnet, the mounting rod 44 and the brush 16 are in a horizontal state. When the brush 16 is driven to clean, the fourth motor 39 drives the fifth screw 40 to rotate. The fifth screw 40 drives the cleaning seat 41 to move through the thread. During the movement, the third spur gear 43 on the cleaning shaft meshes with the second spur rack 45, causing the mounting rod 44 to deflect, so that the opposite surface of the upper end face of the mounting rod 44 contacts another magnet, causing the mounting rod 44 to rotate to a digital state, so that the brush 16 contacts the upper and lower first ropes 10. Due to the attraction of the magnet, the mounting rod 44 is fixed. The fourth motor 39 is then driven to rotate, causing the brush 16 to move back and forth to clean the first ropes 10.

[0048] In some embodiments, the separation box 1 is provided with a discharge port 46 at the lower end of the second support 6; the bottom of the discharge port 46 is provided with an inclined surface 47; a recycling box 18 is slidably connected to the discharge port 46; a receiving box is installed at the lower end of the recycling box 18; an opening is provided on the side of the recycling box 18 near the second support 6; a through hole is provided on the side of the recycling box 18 near the purification box 2; a guide plate 48 is rotatably connected to the recycling box 18 at the through hole; first electric push rods 49 are symmetrically fixedly installed on the separation box 1; each of the first electric push rods 49 is fixedly connected to the recycling box 18; a second electric push rod 50 is installed on the top of the recycling box 18; a scraper 51 is fixedly installed on the second electric push rod 50;

[0049] The first electric push rod 49 can drive the recycling box 18 to move out of or into the separation box 1. When the recycling box 18 is moved out, the guide plate 48 will deflect downward under the action of gravity. Then the second electric push rod 50 drives the scraper 51 to move downward. Then the first electric push rod 49 drives the recycling box 18 to move towards the separation box 1. The scraper 51 will scrape away the debris on the top of the recycling box 18 and sweep the debris into the receiving box through the through hole. The inclined surface 47 of the discharge port 46 is used so that the guide plate 48 will deflect when it encounters the inclined surface 47 during the resetting process of the recycling box 18 until the guide plate 48 is horizontal.

[0050] In some embodiments, the stirring structure includes a sixth motor 52, a seventh motor 53, and stirring blades 58; both the sixth motor 52 and the seventh motor 53 are fixedly connected to the purification chamber 2; the sixth motor 52 is fixedly mounted with a first stirring shaft 54; the seventh motor 53 is fixedly mounted with a second stirring shaft 65 inside the first stirring shaft 54; the first stirring shaft 54 ​​has stirring seats 56 evenly distributed linearly; the stirring seats 56 are rotatably connected to a third stirring shaft 57; the third stirring shaft 57 is fixedly mounted with stirring blades 58; the third stirring shaft 57 is fixedly mounted with a fifth bevel gear inside the first stirring shaft 54; the second stirring shaft 65 has a sixth bevel gear fixedly mounted on the side near the fifth bevel gear; each fifth bevel gear meshes with an adjacent sixth bevel gear.

[0051] After receiving wastewater, the purification tank 2 simultaneously starts the sixth motor 52 and the seventh motor 53. The sixth motor 52 drives the first stirring shaft 54 ​​to rotate, thereby causing the stirring base 56, the third stirring shaft 57, and the stirring blades 58 to rotate around the first stirring shaft 54. The seventh motor 53 drives the second stirring shaft 65 to rotate, and the second stirring shaft 65 drives the third stirring shaft 57 to rotate through the sixth bevel gear and the fifth bevel gear, thereby causing the stirring blades 58 to rotate around the three stirring shafts. In this way, when the wastewater and chemical reagents rotate horizontally, they will also rotate vertically, allowing the wastewater and chemical reagents to react fully.

[0052] In some embodiments, the inlet tube 17 is rotatably connected to two swing shafts 55; a middle seat is fixedly installed between the swing shafts 55 in the separation box 1; a middle shaft 59 is rotatably connected to the middle seat; a seventh bevel gear 60 is symmetrically fixedly installed on the middle shaft 59; an eighth bevel gear 61 is fixedly installed on the swing shafts 55; each of the seventh bevel gears 60 meshes with one of the eighth bevel gears 61; an eighth motor 62 is installed in the separation box 1; the eighth motor 62 is connected to one of the swing shafts 55; each of the swing shafts 55 is fixedly installed with a swing plate 63; one swing plate 63 abuts against the inner wall of the inlet tube 17 near the middle seat, and the other swing plate 63 abuts against the inner wall of the inlet tube 17 near the middle seat.
