Description

Technical Field

[0002] Environmental protection projects refer to projects specifically designed for environmental protection. They are projects that address environmental pollution caused by industrial development, based on a set of assumed goals, and use relevant scientific knowledge and technical means to address and solve environmental pollution problems through the organized activities of a group of people.

[0003] Environmental protection projects will generate a large amount of wastewater, such as construction site sewage. During the construction process, such as drilling, piling, digging, etc., various muddy water and mud generated by washing vehicles and machinery, as well as wastewater containing oil, heavy metals or hazardous chemicals caused by various reasons, construction site wastewater cannot be discharged directly and needs to be treated and recycled.

[0004] Existing wastewater treatment and recycling equipment generally filters the wastewater first, filters out impurities in the wastewater, and then proceeds to the next step of purification. When filtering the wastewater, impurities easily clog the filter, resulting in a low filtration rate, and it is necessary to frequently stop the wastewater filtration to clean up the intercepted impurities, resulting in process delays and low treatment efficiency. At the same time, it is not possible to separate and recover metal substances in the impurities while filtering the impurities, resulting in low practicality. Therefore, the present application proposes an environmental protection engineering wastewater treatment and recycling system. Summary of the Invention

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0049] like Figures 1-11 As shown, an environmental engineering wastewater treatment and recycling system proposed in one embodiment of the present application includes:

[0050] The coagulation cylinder 1 and the filter cylinder 2 are arranged up and down through a bracket. A delivery pipe 3 is connected between the coagulation cylinder 1 and the filter cylinder 2. A valve is provided on the delivery pipe 3. Preferably, the top of the coagulation cylinder 1 is connected to a feed pipe, and the bottom of the filter cylinder 2 is connected to a drain pipe. A stirring mechanism 4 is provided in the coagulation cylinder 1.

[0051] The filtering mechanism 5 includes a collecting ring 501 arranged inside the filter cartridge 2. The longitudinal section of the collecting ring 501 is L-shaped and an annular collecting groove is formed between the collecting ring 501 and the inner wall of the filter cartridge 2. The outer wall of the filter cartridge 2 is provided with a discharge channel 502 connected to the annular collecting groove. The discharge channel 502 is connected to the bottom of the collecting ring 501. The inner wall of the collecting ring 501 is provided with a conical ring net 503. The inner wall of the conical ring net 503 is provided with a conical filter net 504. Preferably, as Figure 3 As shown, the inner side of the conical ring net 503 is lower than the outer side, the outer edge of the conical filter 504 is lower than the conical tip, the outer edge of the conical filter 504 is constructed with side ribs, and the side ribs are higher than the inner side of the conical ring net 503, the conical ring net 503 is symmetrically hinged with an arc-shaped dial plate 505 overlapping the conical ring net 503, the conical filter 504 is coaxially rotated with a shaft 506, and two connecting rods 507 are symmetrically provided on the shaft 506. The ends of the two connecting rods 507 are both provided with an arc-shaped scraper 508 overlapping the conical ring net 503. Preferably, as shown in FIG. Figure 4 As shown, the end of the arc-shaped scraper 508 close to the conical filter 504 is constructed with a transition bevel, and the end of the arc-shaped paddle 505 away from the hinge point is constructed with a transition arc. Since the arc-shaped paddle 505 is hinged on the conical ring net 503 and overlaps with it, under the influence of the conical surface, the arc-shaped paddle 505 rotates around the hinge point, and its end away from the hinge point overlaps the side rib of the conical filter 504. A support rod 5010 is provided on the shaft rod 506, and both ends of the support rod 5010 are provided with a cleaning plate 5011 slidably inserted in the annular aggregate trough. A hydraulic mechanism 509 for driving the shaft rod 506 to rotate by means of water flow is provided on the delivery pipe 3.

[0052] The metal recovery mechanism 6 is provided on the filter cartridge 2 and is in communication with the discharge channel 502, and is used to separate and recover metal objects from impurities;

[0053] When treating the wastewater of the environmental protection project, the valve on the delivery pipe 3 is closed, the wastewater is added to the coagulation drum 1 from the feed pipe, and then a coagulant is added to the wastewater in the coagulation drum 1 from the feed pipe, and the wastewater is stirred by the stirring mechanism 4 so that the wastewater and the coagulant are fully mixed, and the coagulant condenses the fine impurities in the wastewater into solid impurities, and then the valve is opened, and the wastewater is delivered from the delivery pipe 3 to the filter drum 2. When the wastewater is delivered from the delivery pipe 3 to the filter drum 2, the water flow will pass through the conical filter mesh 504, and the impurities in the water will be intercepted by the conical filter mesh 504. Under the influence of the conical surface of the conical filter mesh 504 and the scouring of the water flow, the intercepted impurities will slide to the lower end of the cone, and then slide onto the conical ring net 503, and the shaft rod 506 is driven to rotate by the water power mechanism 509, thereby driving the two connecting rods 507 to rotate, so that the two arcs The curved scraper 508 scrapes along the conical ring net 503. When scraping, the curved scraper 508 drives the impurities to move and drives the impurities to the angle area between the curved scraper 508 and the curved pick plate 505. As the curved scraper 508 continues to move, the end of the curved pick plate 505 away from the hinge point slides from the side guard of the conical filter screen 504 to the outer surface of the curved scraper 508. As the curved scraper 508 continues to move, it will continuously apply a resistance force to the curved pick plate 505. Under the action of the resistance force, the curved pick plate 505 rotates around the hinge point, and during the rotation process, the end away from the hinge point moves along the outer surface of the curved scraper 508, which pushes the impurities in the angle area between the curved scraper 508 and the curved pick plate 505 upward along the conical surface of the conical ring net 503, thereby pushing the intercepted impurities into the annular aggregate groove formed between the aggregate ring 501 and the inner wall of the filter cylinder 2;

[0054] As the shaft 506 continues to rotate, the support rod 5010 is driven to rotate, so that the two cleaning plates 5011 slide along the annular aggregate trough, thereby pushing the impurities located in the annular aggregate trough to move. When the impurities move to the discharge channel 502, the impurities are discharged from the discharge channel 502. When the impurities are discharged from the discharge channel 502, the metal recovery mechanism 6 separates and recovers the metal substances contained in the impurities. The overall structure of the device is that when filtering wastewater, the wastewater flows through the conical filter screen 504, and the water flows directly through it, and the impurities are intercepted. The intercepted impurities will slide to the lower end and slide from the conical filter screen 504 to the conical ring network 503, so that the conical filter screen 504 will not be blocked, ensuring its smooth filtering.

[0055] Then, through the cooperation of the arc scraper 508 and the arc paddle 505, the impurities that slide onto the conical ring net 503 are pushed into the annular aggregate trough formed between the aggregate ring 501 and the inner wall of the filter cylinder 2, and finally the impurities are discharged from the discharge channel 502 through the scraping brush of the cleaning plate 5011. This not only effectively ensures that the filter screen will not be blocked during filtration, but also can clean the intercepted impurities in time. The entire device does not need to be shut down to clean the impurities at the same time, and the subsequent metal recovery mechanism 6 separates and recovers the metal substances in the impurities. The structure of the conical filter screen 504 and the conical ring net 503 makes it have a V-shaped transfer path for impurities to move. When removing impurities, it will not cause excessive leakage of water, and the discharged impurities will not contain too much water, thereby improving practicality.

[0056] like Figure 10 As shown, in some embodiments, the hydrodynamic mechanism 509 includes: a rotating rod 5091, which rotates and passes through the delivery pipe 3, and the rotating rod 5091 is fixed with an impeller 5092 located in the delivery pipe 3, and both ends of the rotating rod 5091 are fixed with a transmission bevel gear 5093; a collar 5094, which is rotatably sleeved on the delivery pipe 3, and the collar 5094 is fixed with a driven bevel gear ring 5095 that is gear-meshed with the two transmission bevel gears 5093, and the collar 5094 is connected to the shaft 506 by a connecting rod 5096. Preferably, the impeller 5092 is a cross-shaped fan blade structure. When water flows along the delivery pipe 3, the water flow will impact the impeller 5092. Under the action of the impact force, the rotating rod 5091 is driven to rotate, and the tooth pressure of the transmission bevel gear 5093 and the driven bevel gear ring 5095 are engaged, thereby driving the ring 5094, and then driving the shaft 506 to rotate through the connection of the connecting rod 5096. The overall structure of the device uses the power generated by the circulation of water as the power source for cleaning the intercepted impurities, which not only reduces energy consumption, but also fully utilizes the circulation kinetic energy of the wastewater, thereby improving environmental protection and practicality.

[0057] like Figure 2 and Figure 9 As shown, in some embodiments, the stirring mechanism 4 includes: a stirring rod 401, which rotates coaxially and passes through the top of the coagulation drum 1, and an outer surface array of one end of the stirring rod 401 located in the coagulation drum 1 is provided with a plurality of stirring blades 402 distributed in a ring shape, and the top of the stirring rod 401 is connected to a motor 403 provided on the coagulation drum 1. The motor 403 works, and its output shaft drives the stirring rod 401 to rotate, thereby driving the plurality of stirring blades 402 to stir the wastewater, so that the coagulant and the wastewater are fully mixed.

[0058] like Figure 11As shown, in some embodiments, a column 7 is provided on the conical ring net 503, and a limit plate 8 is provided at the end of the column 7. One end of the arc-shaped dial plate 505 is rotatably mounted on the column 7. A torsion spring 9 mounted on the column 7 is connected between the limit plate 8 and the arc-shaped dial plate 505. Although affected by the conical surface of the conical ring net 503 and the weight of the arc-shaped dial plate 505 itself, the arc-shaped dial plate 505 will rotate around the hinge point, and the end away from the hinge point will be connected to the conical ring net 503. The side guards of the filter screen 504 overlap, but they overlap with the surface of the conical ring screen 503, which has a little friction resistance. Through the provided torsion spring 9, under the resistance of the arc scraper 508, the arc pick plate 505 will rotate around the hinge point and twist the torsion spring 9. When the arc scraper 508 passes over the arc pick plate 505, the arc pick plate 505 can be quickly reset under the torsion of the torsion spring 9, so as to facilitate the subsequent pushing of impurities again, thereby improving practicality.

[0059] like Figure 6 、 Figure 7 As shown, in some embodiments, the metal recovery mechanism 6 includes: a processing box 601 with an opening at the bottom, which is arranged on the filter cartridge 2 and is connected to the discharge channel 502, and a partition plate 602 is provided at the bottom of the processing box 601; a guide rod 603, which rotates and penetrates the inner wall of one side of the processing box 601, and a rotating drum 604 is fixed on one end of the guide rod 603 located in the processing box 601, and a plurality of magnetic rods 605 distributed in an annular shape are slidably penetrated on the outer surface of the rotating drum 604, and the magnetic rods 605 are fixed on one end of the rotating drum 604. A limit block 606 is provided, and a spring 607 is installed between the limit block 606 and the inner wall of the rotating drum 604, which is sleeved on the guide rod 603; a fixed rod 608 is fixed on the inner wall of the processing box 601 on the side away from the guide rod 603, and a cylinder 6010 located in the rotating drum 604 is fixed on the fixed rod 608, and a avoidance groove 6011 is opened on one side of the cylinder 6010; a linkage member 609 is provided on the coagulation drum 1, and when the stirring rod 401 rotates, the linkage member 609 drives the guide rod 603 to rotate synchronously, such as Figure 6As shown, the partition plate 602 divides the opening of the processing box 601 into two discharge ports, the left one is a metal discharge port, and the right one is a non-metal discharge port. The cylinder 6010 is coaxial with the drum 604. When the limit block 606 overlaps the outer surface of the arc of the cylinder 6010, the spring 607 is in a compressed state. The end of the magnetic rod 605 is located outside the drum 604. When impurities fall from the discharge channel 502, they will fall to the outer surface of the drum 604. When the stirring rod 401 rotates, the linkage 609 drives the guide rod 603 to rotate synchronously, thereby driving the drum 604 to rotate. When the drum 604 rotates, the non-metallic impurities in the impurities are removed. The material is discharged from the non-metallic discharge port, and the metal impurities will be adsorbed on the magnetic rod 605. As the rotating drum 604 continues to rotate, when the magnetic rod 605 rotates to the position of the avoidance groove 6011, the limit block 606 on the magnetic rod 605 will no longer be resisted by the cylinder 6010, so that the spring 607 thereon is released. Under the elastic resistance of the spring 607, the magnetic rod 605 slides and shrinks into the rotating drum 604. When the magnetic rod 605 slides and shrinks, the metal material adsorbed on it will be peeled off by the rotating drum 604, thereby discharging the metal material from the metal discharge port, so as to achieve the effect of separating and recovering the metal material in the impurities.

[0060] like Figure 1 and Figure 9 As shown, in some embodiments, the linkage member 609 includes: a first linkage rod 6091 and a second linkage rod 6092, both of which are rotatably arranged on the coagulation drum 1 through a support; two first bevel gears 6093, respectively fixed at both ends of the first linkage rod 6091; two second bevel gears 6094, one of which is fixed on the stirring rod 401, and the other second bevel gear 6094 is fixed on the second linkage rod 6092, and the two second bevel gears 6094 are respectively engaged with the teeth of the two first bevel gears 6093; a pulley assembly 6095, connected to the second linkage rod 6092 and the guide rod 603 When the stirring rod 401 rotates, the teeth of one of the first bevel gears 6093 and one of the second bevel gears 6094 are engaged, thereby driving the first linkage rod 6091 to rotate, and the teeth of another first bevel gear 6093 and another second bevel gear 6094 are engaged, thereby driving the second linkage rod 6092 to rotate, and then through the linkage of the pulley assembly 6095, the guide rod 603 is driven to rotate. The setting of the linkage part 609 enables the metal recovery mechanism 6 and the stirring mechanism 4 to share a motor 403 as an energy drive, thereby reducing energy consumption and improving energy saving and environmental protection.

[0061] like Figure 1 and Figure 8As shown, in some embodiments, the second linkage rod 6092 includes a first rod body 60921 and a second rod body 60922, the first rod body 60921 and the second rod body 60922 do not overlap each other, another second bevel gear 6094 is fixed on the first rod body 60921, the end of the pulley assembly 6095 away from the guide rod 603 is set on the second rod body 60922, and an adjustment member 60923 is connected between the first rod body 60921 and the second rod body 60922. The adjustment member 60923 is used to adjust the first rod body 60921 to adjust the second bevel gear 6094. The body 60921 and the second rod body 60922 are connected or disconnected. The second linkage rod 6092 is divided into two rod bodies, the first rod body 60921 and the second rod body 60922. The two rod bodies do not overlap with each other, but can be connected or disconnected by the adjustment member 60923. When the wastewater is stirred, the two can be disconnected to reduce the driving load. When the wastewater needs to be filtered and impurities need to be separated, the two can be connected again by the adjustment member 60923, thereby improving the flexibility of environmental protection and energy saving.

[0062] like Figure 8 As shown, in some embodiments, the adjusting member 60923 includes: a rectangular rod 609231, a rectangular groove 609232 coaxially passing through the first rod body 60921 and the second rod body 60922, and the rectangular rod 609231 slides through the two rectangular grooves 609232; a sleeve 609233, which is rotatably set at one end of the rectangular rod 609231, and the sleeve 609233 is threadedly connected to the first rod body 60921. The sleeve 609233 is twisted and rotated to move the rectangular rod 609231. When the rectangular rod 609231 is movably inserted into the two rectangular grooves 609232, it connects the first rod body 60921 and the second rod body 60922. Loosening the sleeve 609233 and withdrawing the rectangular rod 609231 from one of the rectangular grooves 609232 can disconnect the first rod body 60921 and the second rod body 60922.

[0063] like Figure 3 As shown, in some embodiments, a first brush plate 10 is provided on each of the two connecting rods 507, and both of the first brush plates 10 are in contact with and overlap the conical filter screen 504. Through the provision of the first brush plates 10, when the connecting rod 507 rotates, the first brush plates 10 scrape the outer surface of the conical filter screen 504, further improving the anti-clogging performance of the conical filter screen 504, ensuring the smoothness of the filtration, and thus improving practicality.

[0064] like Figure 2 and Figure 9As shown, in some embodiments, a support plate 11 is provided on the stirring rod 401, and a second brush plate 12 is provided at both ends of the support plate 11. The two second brush plates 12 are both in contact with and overlap the inner wall of the coagulation drum 1. When the stirring rod 401 rotates, the support plate 11 is driven to rotate, so that the second brush plate 12 scrapes the inner wall of the coagulation drum 1 to prevent impurities from remaining on the inner wall of the coagulation drum 1, thereby improving practicality.
