Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a rapid industrial wastewater treatment device. Background Technology

[0002] A rotary drum screen is a solid-liquid separation device used in the pretreatment of industrial wastewater. It typically consists of a rotating cylindrical screen (drum). Wastewater enters the screen from one end of the drum. During rotation, the liquid passes through the screen openings and is discharged, while solids larger than the openings are retained inside the drum. To facilitate slag discharge, the inner wall of the drum is often equipped with helical blades. These rotating blades push the solids towards the discharge port. Due to the complex composition of industrial wastewater, the retained solids are often sticky or irregularly shaped. After dewatering, these solids deposit at the bottom of the drum and adhere to the screen, easily causing clogging and affecting screening efficiency and throughput. This also hinders the discharge of solids from the drum. Current technology often uses spray pipes outside the drum to wash the screen. However, this method only washes the outside of the drum, limiting its cleaning capacity. Summary of the Invention

[0003] This invention addresses the issue of solid slag deposited at the bottom of existing drum screens being difficult to transport and affecting the drum's screening capacity. It proposes a rapid industrial wastewater treatment device by installing a sealing plate at the bottom of the drum to retain some liquid. The liquid can promote the dispersion of solid slag and improve the efficiency of solid slag transport inside the drum.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rapid industrial wastewater treatment device includes a base and a horizontally arranged mesh-type drum. The drum is rotatably connected to the base, and spiral blades are installed inside the drum. A liquid guiding channel and an arc-shaped sealing box are arranged below the drum, sequentially between the inlet and outlet ends of the drum. An arc-shaped sealing plate is installed inside the sealing box, and the sealing plate is slidably connected to the sealing box in the vertical direction. The sealing plate seals the lower arc-shaped part of the drum located inside the sealing box. When the sealing plate is in contact with the drum, the highest point of the sealing plate is below the lowest point of the spiral blades. The sealing plate and spiral blades combine to form a liquid collection space in the lower part of the drum.

[0005] The base is equipped with a functional cylinder, and a piston plate is movably connected inside the functional cylinder. The chamber on one side of the piston plate is connected to the sealing box. The piston plate moves back and forth to realize the liquid inlet and return actions of the sealing box and the liquid collection space. The liquid inlet and return actions are performed alternately to form the cleaning of the roller mesh inside the sealing box.

[0006] Preferably, the piston plate is fixedly connected to a movable rod, the movable rod is hinged to the first end of the rocker arm, the second end of the rocker arm is hinged to the long end of the cam, and the cam moves the piston plate back and forth by rotating.

[0007] Preferably, the industrial wastewater rapid treatment device further includes a first inlet pipe, which is connected to the sealed box via a second inlet pipe. The first inlet pipe is also connected to the second outlet pipe of the liquid guide tank, and the second inlet pipe of the sealed box is connected to the chamber of the functional cylinder via a liquid guide pipe.

[0008] Preferably, a pull rod is fixedly connected to the lower end of the sealing plate. The axis of the pull rod is vertically set, and the lower end of the pull rod extends from the lower part of the sealing box. The base is provided with a driving component for driving the pull rod to move axially.

[0009] Preferably, the sealed box is further provided with a first limiting seat and a second limiting seat. The first limiting seat is fixedly connected to the lower part of the sealing plate, and the second limiting seat is fixedly connected to the sealed box. The positions of the first limiting seat and the second limiting seat correspond, and the pull rod passes through the first limiting seat and the second limiting seat.

[0010] Preferably, a protective box is provided on the base, the upper part of the roller is located inside the protective box, the protective box forms a flow guiding space outside the roller, and the protective box is provided with a third water outlet pipe.

[0011] Preferably, the protective box is equipped with a water guide pipe, the axis of which is parallel to the axis of the roller, and multiple nozzles are provided on the water guide pipe. The multiple nozzles are evenly distributed along the water guide pipe, and the outlet of the nozzles faces the roller.

[0012] Preferably, the inside of the roller is provided with a water storage tank for receiving water from the nozzle, and a protective box is fixedly connected to the end of the water storage tank.

[0013] Preferably, the water guide pipe is connected to the second water outlet pipe of the liquid guide tank.

[0014] Preferably, sleeves are connected to both ends of the roller, and the sleeves are rotatably connected to the protective box. One of the sleeves is provided with a gear ring, and the base is provided with a gear for driving the gear ring to rotate.

[0015] The beneficial effects of this invention are: The drum in this rapid industrial wastewater treatment device is used to filter wastewater and separate solid residue from it. The sealing plate at the bottom of the drum and the spiral blades inside the drum combine to form a liquid collection space, which can store a small amount of liquid. The solid residue at the bottom of the drum is located in this liquid. The solid residue is dispersed in the liquid due to buoyancy. As the drum rotates, the spiral blades convey the mixture, thereby realizing the conveying of solid residue inside the drum. This reduces the probability of solid residue adhering to the inner wall of the drum and also improves the solid residue conveying efficiency.

[0016] The sealing plate of this rapid industrial wastewater treatment device is located inside the sealing box. When the sealing plate separates from the bottom of the drum, the sealing box can form a temporary container at the bottom of the drum. Filtered liquid is introduced into the temporary container, and the liquid flows back and forth between the sealing box and the drum, forming a double-sided flushing and cleaning of the screen surface at the bottom of the drum, reducing the possibility of screen clogging.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-2An industrial wastewater rapid treatment device includes a base 1, a protective box 6, and a roller 2. The upper part of the roller 2 is located inside the protective box 6, and the lower part of the roller 2 is located inside the base 1. The base 1 and the protective box 6 are isolated by the bottom plate of the protective box 6. A first sleeve 201 is fixedly connected to the first end of the roller 2, and a second sleeve 202 is fixedly connected to the second end of the roller 2. A third sleeve 62 and a fourth sleeve 63 are fixedly installed on the protective box 6. The first sleeve 201 is rotatably sleeved on the third sleeve 62 through a slewing bearing, and the second sleeve 202 is rotatably sleeved on the fourth sleeve 63 through a slewing bearing. The roller 2 can rotate inside the protective box 6.

[0021] Further reference Figure 3 The first sleeve 201 has an annular groove 203, inside which a gear ring is fitted. The base 1 has a gear 14 and a first motor 15, with the gear 14 meshing with the gear ring. The gear 14 is fixedly sleeved on the second end of a connecting shaft 141, which is rotatably connected to the base 1. The first end of the connecting shaft 141 is fixedly sleeved with a first pulley 142. The output shaft of the first motor 15 is coaxially connected to a second pulley 151, which is connected to the first pulley 142 via a belt 16. The first motor 15 can rotate the second pulley 151, which in turn drives the first pulley 142, the connecting shaft 141, and the gear 14 to rotate via the belt 16. The gear 14 can drive the first sleeve 201 to rotate, thus achieving the rotation of the roller 2.

[0022] refer to Figure 3 and Figure 4 The roller 2 is made of mesh material. Multiple ring-shaped support rods 21 are provided inside the roller 2. The support rods 21 are fixedly connected between the first sleeve 201 and the second sleeve 202. The support rods 21 support the mesh surface of the roller 2.

[0023] Further reference Figure 1 A water guide trough 10 is fixedly connected to the protective box 6, located at the water inlet end of the drum 2. The water guide trough 10 is inclined, with its first end higher than its second end. The first end of the water guide trough 10 is located outside the drum 2, and the second end extends into the interior of the drum 2. The water guide trough 10 is used to guide sewage into the drum 2. A spiral blade 22 is installed inside the drum 2, and the drum 2 and the spiral blade 22 rotate synchronously. After the sewage enters the drum 2 from the water guide trough 10, the screen surface filters the sewage. The sewage passes through the screen surface, while the solid residue inside the sewage remains inside the drum 2, achieving separation of sewage from the internal solid residue. The spiral blade 22 can push the solid residue inside the drum 2 to move, causing the solid residue to be discharged from the discharge end of the drum 2.

[0024] refer to Figure 3A collection box 12 is also provided on the base 1. The collection box 12 is located below the discharge end of the drum 2 and is used to collect solid slag coming out of the drum 2.

[0025] The base 1 is internally equipped with a liquid guiding channel 5 and a sealing box 3, which are located below the roller 2. The liquid guiding channel 5 and the sealing box 3 are arranged sequentially between the water inlet and outlet ends of the roller 2. The upper parts of the liquid guiding channel 5 and the sealing box 3 are fixedly connected to the bottom plate of the protective box 6. The liquid guiding channel 5, the sealing box 3, and the protective box 6 isolate the mesh surface of the roller 2, preventing liquid from entering the base 1 and thus preventing the liquid from affecting the normal operation of the internal components of the base 1.

[0026] The liquid guiding tank 5 is located below the second end of the water guiding tank 10. After the sewage enters the drum 2, it is filtered. The filtered liquid enters the liquid guiding tank 5 and is discharged from the second outlet pipe 51 of the liquid guiding tank 5.

[0027] refer to Figure 4 The aforementioned sealing box 3 is arc-shaped, and a sealing plate 4, also arc-shaped, is installed inside the sealing box 3. The sealing plate 4 is used to seal the arc-shaped opening at the top of the sealing box 3. The sealing plate 4 is slidably connected to the sealing box 3 in the vertical direction. A pull rod 41 is fixedly connected to the lower end of the sealing plate 4. The axis of the pull rod 41 is vertically set, and the lower end of the pull rod 41 extends from the bottom of the sealing box 3. The base 1 is equipped with an adjusting cylinder 7. The axis of the adjusting cylinder 7 is vertically set, and the working end of the adjusting cylinder 7 is connected to the lower end of the pull rod 41 through a connecting rod 19. The adjusting cylinder 7 is an electric cylinder, which is used to drive the pull rod 41 to move axially, thereby realizing the movement of the sealing plate 4 in the vertical direction.

[0028] Furthermore, the aforementioned sealing plate 4 corresponds to the lower arc-shaped part of the roller 2. When the sealing plate 4 is in contact with the roller 2, and the sealing plate 4 is located at the upper limit position of the sealing box 3, the sealing plate 4 seals the lower arc-shaped part of the roller 2 inside the sealing box 3, and also seals the arc-shaped opening at the top of the sealing box 3. (Reference) Figure 3 and Figure 4 The axis of the drum 2 is horizontally positioned, and the spiral blades 22 have a certain height inside the drum 2. When the sealing plate 4 seals the bottom of the drum 2, the sealing plate 4 and the adjacent spiral blades 22 combine to form a liquid collection space 23. The liquid collection space 23 can store a small amount of liquid, and the solid slag at the bottom of the drum 2 will be located in this liquid. The solid slag will be dispersed in the liquid due to buoyancy, forming a mixture. The rotation of the drum 2 causes the spiral blades 22 to convey the mixture, thereby realizing the conveying of solid slag inside the drum 2. In this embodiment, the solid conveying of solid slag inside the drum 2 is changed to liquid conveying, reducing the probability of solid slag adhering to the inner wall of the drum 2, and also improving the solid slag conveying efficiency.

[0029] It is worth noting that the highest point of the sealing box 3 and the sealing plate 4 is located below the lowest point of the spiral blade 22. The bottom plate of the protective box 6 is fixedly connected to the highest part of the sealing box 3, and the bottom plate of the protective box 6 is also lower than the lowest point of the spiral blade 22. The protective box 6 is equipped with a third water outlet pipe, which is connected to the bottom plate of the protective box 6. The third water outlet pipe is used to drain the liquid inside the protective box 6. When the liquid level inside the liquid collection space 23 reaches the bottom plate of the protective box 6, the liquid will be discharged from the third water outlet pipe. Therefore, the liquid level inside the liquid collection space 23 will not be higher than the lowest point of the spiral blade 22. The spiral blade 22 can act as an isolator to isolate the liquid inside the adjacent liquid collection space 23 and prevent liquid backflow.

[0030] In this embodiment, an isolation layer is provided at the bottom of the collection tank 12, and the isolation layer has a leakage hole. The liquid in the mixture can flow from the leakage hole to the bottom of the collection tank 12. A first drain pipe is provided at the bottom of the collection tank 12 for liquid discharge.

[0031] The aforementioned sealed box 3 is equipped with a second inlet pipe 31 and a first outlet pipe 32. The second inlet pipe 31 is used for liquid inlet into the sealed box 3, and the first outlet pipe 32 is used for liquid discharge from inside the sealed box 3. This rapid industrial wastewater treatment device also includes a first inlet pipe 17, which is connected to the sealed box 3 via the second inlet pipe 31. The first inlet pipe 17 is also connected to the second outlet pipe 51 of the liquid guiding tank 5. A first pump body is installed on the first inlet pipe 17, which is used to guide the filtered liquid from the liquid guiding tank 5 into the sealed box 3, thereby increasing the liquid level inside the sealed box 3.

[0032] When the mesh surface of roller 2 needs to be rinsed, the adjusting cylinder 7 drives the pull rod 41 to move axially, separating the sealing plate 4 from roller 2. At this time, roller 2 is connected to the sealing box 3. The first pump body introduces some liquid from the liquid guide groove 5 into the sealing box 3. The liquid in the sealing box 3 will enter the interior of roller 2 from below, and the liquid will rinse the outer surface of roller 2. If the liquid leaves the liquid sealing box 3, the liquid level inside roller 2 drops to the interior of the sealing box 3, and the liquid can then rinse the inner surface of roller 2.

[0033] To enable repeated liquid inlet and outlet of the sealed box 3, a functional cylinder 8 is provided on the base 1. The functional cylinder 8 has a chamber 82 inside, which is used to store liquid. The chamber 82 is connected to the second water inlet pipe 31 of the sealed box 3 through a liquid guide pipe 83.

[0034] Further reference Figure 4The functional cylinder 8 has a piston plate 81 inside, which is slidably connected to the functional cylinder 8. A chamber 82 is located on one side of the piston plate 81, and a movable rod 84 is fixedly connected to the other side of the piston plate 81. One end of the movable rod 84 extends to the outside of the functional cylinder 8. The end of the movable rod 84 outside the functional cylinder 8 is hinged to the first end of a rocker arm 85, and the second end of the rocker arm 85 is hinged to the long end of a cam 9. A second motor 18 is mounted on the base 1, and the output shaft of the second motor 18 is fixedly fitted onto the cam 9. The second motor 18 can drive the cam 9 to rotate, and the cam 9 can pull the movable rod 84 through the rocker arm 85, causing the movable rod 84 and the piston plate 81 to reciprocate.

[0035] The reciprocating movement of the piston plate 81 changes the volume of the chamber 82. When the valves of the first inlet pipe 17 and the first outlet pipe 32 are closed, the chamber 82 is in a separate communication state with the sealing box 3. When the volume of the chamber 82 increases, the liquid inside the sealing box 3 will enter the chamber 82, and the liquid level inside the roller 2 will drop to the inside of the sealing box 3, i.e., a backflow action will occur between the sealing box 3 and the roller 2, allowing the liquid to rinse the inner surface of the roller 2; see reference. Figure 6 When the volume of chamber 82 decreases, the liquid inside chamber 82 will enter the sealing box 3. The liquid will then enter the roller 2 from below, thus performing the liquid inlet action of the sealing box 3 and roller 2. The liquid will then rinse the outer surface of roller 2. The volume change of chamber 82 realizes the liquid inlet and return actions of the sealing box 3 and the liquid collection space 23. The liquid inlet and return actions alternate, forming a double-sided rinsing of the liquid surface of roller 2. Since roller 2 is continuously rotating, the liquid inside the sealing box 3 can clean the entire surface of roller 2.

[0036] The sealed box 3 is further provided with a first limiting seat 33 and a second limiting seat 34. The first limiting seat 33 is fixedly connected to the lower part of the sealing plate 4, and the second limiting seat 34 is fixedly connected to the sealed box 3. The positions of the first limiting seat 33 and the second limiting seat 34 correspond, and the pull rod 41 passes through the first limiting seat 33 and the second limiting seat 34. The second limiting seat 34 is used to restrict the positional movement of the first limiting seat 33, that is, to restrict the position of the sealing plate 4, so as to prevent the sealing plate 4 from blocking the first water outlet pipe 32.

[0037] Further reference Figure 1The protective box 6 has a water guide pipe 13 inside, which is fixedly connected to the inner wall of the protective box 6. The axis of the water guide pipe 13 is parallel to the axis of the roller 2. Multiple nozzles 131 are provided on the water guide pipe 13, which are evenly arranged along the water guide pipe 13, with the outlet of the nozzles 131 facing the roller 2. The water guide pipe 13 is connected to the second outlet pipe 51 of the liquid guide tank 5 through a third inlet pipe. A second pump body is provided on the third inlet pipe. The second pump body is used to guide the liquid inside the liquid guide tank 5 into the water guide pipe 13, so that the nozzles 131 spray the roller 2. The spray water sprays the outer surface of the roller 2 to remove the solid residue left on the screen surface of the roller 2. In this embodiment, the spraying of the spray pipe is intermittent, which is used to assist in the removal of solid residue on the screen surface of the roller 2.

[0038] The aforementioned protective box 6 forms a flow guiding space 61 outside the roller 2, allowing the sprayed liquid to enter the flow guiding space 61 and be discharged from the third water outlet pipe of the protective box 6.

[0039] In this embodiment, reference Figure 1 and Figure 4 The drum 2 has a water storage tank 11 inside, and a protective box 6 is fixedly connected to the end of the water storage tank 11. The water storage tank 11 is mainly used to collect the spray water from the nozzle 131. The spray water contains fine solid residue, preventing the spray water from re-entering the drum 2. The water storage tank 11 is connected to a second drain pipe, which guides the spray water into a collection box 12. The collection box 12 is located below the discharge end of the drum 2.

[0040] The industrial wastewater rapid treatment device in this embodiment has a mixed-liquid discharge function and a double-sided drum rinsing function. The specific working process is as follows: Step A1: Adjust cylinder 7 drives pull rod 41 to move axially, so that sealing plate 4 is located at the upper limit position of sealing box 3. At this time, sealing plate 4 is in contact with roller 2. Sealing plate 4 seals the lower arc-shaped part of roller 2 inside sealing box 3, and also seals the arc-shaped opening at the top of sealing box 3. The first motor 15 drives the second pulley 151 to rotate. The second pulley 151 drives the first pulley 142, the connecting shaft 141 and the gear 14 to rotate through the belt 16. The gear 14 drives the first sleeve 201 to rotate, thereby realizing the rotation of the drum 2. Step A2: Wastewater enters drum 2 from water guide trough 10. The wastewater passes through the mesh surface of drum 2, and the filtered liquid enters liquid guide trough 5. The solid residue inside the wastewater remains inside drum 2, achieving separation of wastewater and internal solid residue. Due to gravity, the solid residue generally stays at the bottom of drum 2. The sealing plate 4 and the adjacent spiral blade 22 are combined at the bottom of drum 2 to form liquid collection space 23. Liquid collection space 23 can store a small amount of liquid. The solid residue at the bottom of drum 2 will enter the liquid. The solid residue will be dispersed in the liquid due to buoyancy, forming a mixture. The spiral blade 22 rotates synchronously with drum 2, and the spiral blade 22 conveys the mixture, thereby realizing the conveying of solid residue inside the drum. The mixture will be discharged from the discharge end of drum 2. Since the solid residue is dispersed in the mixture, the probability of solid residue adhering to the drum is reduced, and the solid residue conveying efficiency is also improved. Meanwhile, the second pump body is used to guide the liquid inside the liquid guide tank 5 into the water guide pipe 13, so that the nozzle 131 sprays the roller 2, and the spray water sprays the outer side of the roller 2 intermittently to help remove the solid residue left on the screen surface of the roller 2. Step A3: When the mesh surface of roller 2 needs to be rinsed, keep the chamber 82 of the functional cylinder 8 at its minimum volume, and drive the pull rod 41 of the adjusting cylinder 7 to move downwards. Separate the sealing plate 4 from the roller 2. At this time, the roller 2 is connected to the sealing box 3. The first pump body introduces liquid from the liquid guide groove 5 into the sealing box 3. The sealing box 3 is filled with liquid, and the liquid collection space 23 of the roller 2 is also filled with liquid. Close the valves of the first water inlet pipe 17 and the first water outlet pipe 32. The second motor 18 drives the cam 9 to rotate. The cam 9 can be pulled by the swing rod 85. The movable rod 84 causes the movable rod 84 and the piston plate 81 to reciprocate. When the volume of the chamber 82 increases, the liquid inside the sealed box 3 will enter the chamber 82, and the liquid level inside the roller 2 will drop to the inside of the sealed box 3. The liquid can then rinse the inner side of the roller 2. When the volume of the chamber 82 decreases, the liquid inside the chamber 82 will enter the sealed box 3. The liquid will enter the inside of the roller 2 from below, and the liquid will rinse the outer side of the roller 2, thus achieving double-sided rinsing of the mesh surface of the roller 2. Step A4: When the mesh surface of the roller 2 is washed, keep the chamber 82 of the functional cylinder 8 at its minimum volume, the second motor 18 stops working, the adjusting cylinder 7 drives the pull rod 41 to move upward, and the sealing plate 4 is in contact with the roller 2. At this time, the sealing plate 4 seals the lower arc of the roller 2 located inside the sealing box 3. Open the first water outlet pipe 32 to drain the water inside the sealing box 3.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
