Description

Technical Field

[0001] This invention relates to the field of port wastewater treatment. More specifically, this invention relates to a device for treating powdery wastewater in bulk cargo ports. Background Technology

[0002] Bulk cargo ports refer to port facilities used for loading and unloading bulk cargoes (such as ore, coal, and grain). Wastewater containing mineral powder particles generated during the loading and unloading of bulk cargoes such as ore is called powdery wastewater. Powdery wastewater is unavoidable during the loading and unloading process at bulk cargo port terminals. The traditional method is to install drainage ditches laterally (along the width of the wharf) at the wharf, and then discharge the treated wastewater from the land-based drainage pipes. The powdery wastewater contains valuable magnetic powder, resulting in significant waste. Existing terminal wastewater treatment facilities are not only technologically outdated, but many are also dilapidated, and older wharves even lack wastewater treatment equipment altogether, making it difficult to meet increasingly stringent environmental protection requirements. Existing terminal wastewater treatment equipment cannot be installed in conjunction with existing wharf conditions and requires occupying the wharf's operating area. Most wharves... Wastewater treatment equipment cannot recover high-value magnetic powder. For example, utility model patent CN208561947U discloses a wastewater treatment device for a quarry wharf, including a front cover, inlet, inspection port, ventilation port, spiral agitator, circulation pipe, positioning pin, support column, and support plate. The inlet is embedded in the surface of the front cover, the ventilation port is parallel to the inspection port, the outer surface of the spiral agitator is welded to the lower end of the ventilation port, the circulation pipe is fixed to the outer surface of the spiral agitator by the positioning pin, and the upper surface of the support column is connected to the lower end of the spiral agitator. By setting up the spiral agitator, the propeller activates the chemical cleaning components in the chemical cleaning layer, maximizing the cleaning of wastewater and improving wastewater treatment efficiency. Therefore, the above-mentioned wastewater treatment equipment for a quarry wharf still has the following drawbacks: First, it requires the use of the wharf's operating area; second, it cannot recover high-value magnetic powder. Summary of the Invention

[0010] Preferably, the sedimentation tank includes a water level control unit and a powder collection unit arranged sequentially from top to bottom. The water level control unit and the powder collection unit are detachably and sealed together. The drain pipe is located at the lower part of the water level control unit. The water level control unit is equipped with a water level sensor. The drain pipe is equipped with a control valve. The water level sensor and the control valve are both electrically connected to a controller.

[0011] Preferably, the outer wall of the water level control unit is provided with a clamp mounting seat, and the clamp mounting seat is provided with a clamp that connects to the wharf pile foundation; the clamp mounting seats of adjacent sedimentation tanks are staggered in the vertical direction.

[0012] Preferably, the large-volume magnetic suction pool is disposed above the sedimentation tank, and the bottom of the large-volume magnetic suction pool is provided with a first seepage hole communicating with the sedimentation tank.

[0013] Preferably, there are two small-volume magnetic suction pools. Each small-volume magnetic suction pool includes a small-volume magnetic suction pool body and a connecting pipe disposed at the bottom of the small-volume magnetic suction pool body. The bottom of the connecting pipe is connected to the bottom of the large-volume magnetic suction pool through a flange. The bottom of the connecting pipe is provided with a second seepage hole that connects to the sedimentation tank.

[0014] Preferably, any small-volume magnetic chuck body includes an integrally formed cylindrical portion and a conical portion.

[0015] Preferably, a pair of small-volume magnetic absorbing pool bodies are disposed on a small-volume magnetic absorbing pool base, the bottom of the small-volume magnetic absorbing pool base is provided with a flange connected to the connecting pipe, and the tapered part of the small-volume magnetic absorbing pool body is disposed inside the small-volume magnetic absorbing pool base.

[0016] Preferably, the first magnetic attraction structure includes:

[0017] A first motor is mounted on a first motor mounting bracket, which is located on the inner edge of the small-volume magnetic accumulator body.

[0018] Multiple first magnetic chucks are connected to the motor shaft of the first motor and rotate with the motor shaft of the first motor. The first magnetic chucks are inclined and located close to the inner wall of the conical part of the small volume magnetic chuck body.

[0019] Preferably, the second magnetic attraction structure includes:

[0020] The second motor is mounted on the base of the small-volume magnetic accumulator and the motor shaft of the second motor extends into the large-volume magnetic accumulator.

[0021] Multiple second magnetic holders are connected to the motor shaft of the second motor and rotate with the motor shaft of the second motor. The second magnetic holders are located near the bottom of the large-volume magnetic pool.

[0022] The present invention has at least the following beneficial effects:

[0023] Firstly, the bulk cargo port powdery water treatment device provided by the present invention includes a water collection tank, a magnetic suction component and a sedimentation tank arranged sequentially from top to bottom. The magnetic suction component is provided with a first magnetic suction structure and a second magnetic suction structure, which can recover high-value magnetic powder in the powdery water and improve the economic efficiency of the bulk cargo port powdery water treatment device.

[0024] Secondly, the bulk cargo port powdery water treatment device provided by the present invention can be detachably installed between a pair of wharf pile foundations without occupying the wharf operation area. The drainage pipe set at the bottom of the sedimentation tank can be connected to the existing wharf drainage ditch, making full use of the existing wharf conditions, requiring little modification to the existing wharf, and having strong integration with the existing wharf. It can be applied to the vast majority of existing bulk cargo ports.

[0025] Thirdly, the bulk cargo port powdery water treatment device provided by the present invention has a first guide plate and a second guide plate on its water collection tank, which respectively guide the water to a small volume magnetic suction tank and a large volume magnetic suction tank. The installation height of the second guide plate is higher than that of the first guide plate. The powdery water with a small flow rate flows into the small volume magnetic suction tank for treatment through the first guide plate, while the powdery water with a large flow rate flows into the small volume magnetic suction tank and the large volume magnetic suction tank for simultaneous treatment through the first guide plate and the second guide plate. It is suitable for use at wharves with different flow rates of powdery water and has strong applicability.

[0026] Fourth, the bulk cargo port powder-containing water treatment device provided by the present invention has a sedimentation tank and a wharf pile foundation that can be detached. It can periodically recover the magnetic powder adsorbed in the small volume magnetic suction tank and the large volume magnetic suction tank, and at the same time clean the sediment at the bottom of the sedimentation tank. It is convenient to use and has low cost.

[0027] Fifth, the bulk cargo port powder-containing water treatment device provided by the present invention has a water level sensor in the sedimentation tank and a control valve on the drain pipe. When the water level in the sedimentation tank reaches a preset value, the drain pipe is opened to discharge the settled water in the sedimentation tank into the dock drainage ditch. This ensures that the powder in the sedimentation tank is fully settled and that the powder-containing water treatment device can be used continuously, resulting in high treatment efficiency.

[0028] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0032] Figure 4 This is a schematic diagram of the installation of a pair of small-volume magnetic chucks in another technical solution of the present invention. Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0034] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0035] like Figures 1-4 As shown, the present invention provides a powdery water treatment device for bulk cargo ports, comprising:

[0036] A sedimentation tank is detachably installed between a pair of wharf piles 1, which are arranged along the extension direction of the wharf. The sedimentation tank is installed above the water surface and has a drainage pipe 19 at its lower part.

[0037] A magnetic suction assembly is disposed above the sedimentation tank, comprising a large-volume magnetic suction tank 22 and a small-volume magnetic suction tank arranged sequentially from the sedimentation tank upwards. Both the large-volume magnetic suction tank 22 and the small-volume magnetic suction tank are configured to communicate with the sedimentation tank and allow a small flow of powdery water to pass through. Both the small-volume magnetic suction tank and the large-volume magnetic suction tank 22 are open, and the overflow water from the top of the small-volume magnetic suction tank flows into the large-volume magnetic suction tank 22.

[0038] A water collection trough 12 is provided below the pier surface layer 11 along the extension direction of the pier, and the pier surface layer 11 is provided with a drainage hole that connects to the water collection trough 12. The bottom of the water collection trough 12 is provided with a first guide plate 7 that guides the flow to the small volume magnetic suction pool, and the side is provided with a second guide plate 9 that guides the flow to the large volume magnetic suction pool 22.

[0039] The small-volume magnetic absorbing pool and the large-volume magnetic absorbing pool 22 are respectively equipped with a first magnetic absorbing structure and a second magnetic absorbing structure to absorb magnetic powder in the powder-containing water.

[0040] In the above technical solutions, such as Figure 1 or Figure 2 As shown, the bulk cargo port powdery water treatment device is suitable for wharves where the wharf pile foundation 1 is a pile, such as... Figure 1 or Figure 2 As shown, the wharf structure includes wharf pile foundations 1 arranged sequentially along the wharf's extension direction. Multiple wharf pile foundations 1 are provided with crossbeams 3 along the wharf's width direction, and multiple longitudinal beams 4 are arranged on the crossbeams 3. The wharf surface layer 11 is set on the longitudinal beams 4. The bulk cargo port dusty water treatment device includes, from top to bottom, a water collection trough 12, a magnetic suction component, and a sedimentation tank. The water collection trough 12 is located below the wharf surface layer 11. The wharf surface layer 11 has drainage holes connected to the water collection trough 12. Dusty water (including flushing water) generated during the bulk cargo port loading and unloading process flows into the water collection trough 12 through the drainage holes on the wharf surface layer 11. The water collection trough 12 is arranged along the wharf's extension direction. Along the wharf's width direction, the number of water collection troughs 12 corresponds to the number of sedimentation tanks. That is, according to the actual demand for dusty water discharge from the wharf, multiple sedimentation tanks can be set along the wharf's width direction, and multiple water collection troughs 12 should also be set for the corresponding multiple sedimentation tanks. The water collection trough 12 can quickly and temporarily store the powdery water generated on the wharf surface layer 11 in its inner cavity, reducing the water accumulation phenomenon on the wharf surface layer 11.

[0041] like Figure 3As shown, in the above technical solution, the magnetic suction assembly is located below the water collection tank 12. The powder-containing water in the water collection tank 12 is gradually guided to the magnetic suction assembly for treatment via the first guide plate 7 and the second guide plate 9. The first guide plate 7 and the second guide plate 9 are set at different heights. The contact points between the first guide plate 7 and the second guide plate 9 and the water collection tank 12 are respectively provided with a first slot 71 and a second slot 91. The magnetic suction assembly includes a small-volume magnetic suction pool and a large-volume magnetic suction pool 22. The small-volume magnetic suction pool is located above the large-volume magnetic suction pool 22. Water overflowing from the small-volume magnetic suction pool can flow into the large-volume magnetic suction pool 22. When the amount of powder-containing water in the water collection tank 12 is small, the first guide plate 7 and the second guide plate 9 are installed at a lower height. The guide plate 7 diverts a small portion of the powdery water in the collection tank 12 to a small-volume magnetic wicking tank for treatment before directly entering the sedimentation tank for settling. When the amount of powdery water in the collection tank 12 is large, the first guide plate 7, which is installed at a lower height, diverts a small portion of the powdery water in the collection tank 12 to the small-volume magnetic wicking tank for treatment, while the second guide plate 9, which is installed at a higher height, diverts the powdery water in the collection tank 12 to a large-volume magnetic wicking tank 22 for treatment, and then further introduces it into the sedimentation tank for settling. If the powdery water in the small-volume magnetic wicking tank overflows into the large-volume magnetic wicking tank 22, it will be treated in the large-volume magnetic wicking tank 22. The small-volume magnetic wicking tank and the large-volume magnetic wicking tank 22 are respectively equipped with a first magnetic wicking structure and a second magnetic wicking structure to absorb the magnetic powder in the powdery water. This configuration can adapt to the use of docks with different flow rates of powdery water and has strong applicability.

[0042] In the above technical solution, the sedimentation tank is located below the magnetic adsorption component. After the powder-containing water is treated by the magnetic adsorption component, it absorbs most of the magnetic powder and enters the sedimentation tank to further precipitate other solid powders. The sedimentation tank is detachably connected to the wharf pile foundation 1. It can periodically recover the magnetic powder adsorbed in the small volume magnetic adsorption tank and the large volume magnetic adsorption tank 22, and at the same time clean the sediment at the bottom of the sedimentation tank regularly. It is convenient to use, easy to maintain, and low in cost.

[0043] In one of the technical solutions, the sedimentation tank includes a water level control unit 18 and a powder collection unit 20 arranged sequentially from top to bottom. The water level control unit 18 and the powder collection unit 20 are detachably and sealed together. The drain pipe 19 is located at the lower part of the water level control unit 18. A water level sensor is provided inside the water level control unit 18. A control valve is provided on the drain pipe 19. Both the water level sensor and the control valve are electrically connected to a controller.

[0044] In the above technical solution, the sedimentation tank is configured with a detachable water level control unit 18 and a powder collection unit 20 arranged from top to bottom. The lower powder collection unit 20 can be directly disassembled to clean the sediment at the bottom of the sedimentation tank. This fully considers the low proportion of magnetic powder in the sediment and the significant difference between the magnetic powder recovery cycle and the sediment cleaning cycle; therefore, only the lower powder collection unit 20 needs to be disassembled to clean the sediment. When the water level in the sedimentation tank reaches a preset value, the drain pipe 19 opens to discharge the settled water into the dock drainage ditch. This ensures sufficient sedimentation of the powder in the sedimentation tank and continuous operation of the powder-containing water treatment device, resulting in high treatment efficiency. One implementation of the detachable and sealed connection between the water level control unit 18 and the powder collection unit 20 involves providing ear plates at the connection point, with a sealing strip between the two ear plates. Sealing strips are also provided at the contact points between the water level control unit 18 and the powder collection unit 20.

[0045] In one technical solution, the outer wall of the water level control unit 18 is provided with a clamp 17 mounting seat 2, and the clamp 17 mounting seat 2 is provided with a clamp 17 connected to the wharf pile foundation 1; the clamp 17 mounting seats 2 of adjacent sedimentation tanks are staggered in the vertical direction, and the detachable connection between the sedimentation tank and the wharf pile foundation 1 is realized through the clamp 17 structure. When the installation density of sedimentation tanks is high, the clamp 17 mounting seats 2 of adjacent sedimentation tanks are staggered in the vertical direction to facilitate the installation of sedimentation tanks.

[0046] In one technical solution, the large-volume magnetic absorbing tank 22 is positioned above the sedimentation tank, and the bottom of the large-volume magnetic absorbing tank 22 has a first seepage hole communicating with the sedimentation tank. The top of the sedimentation tank is provided with a partial cover plate. The large-volume magnetic absorbing tank 22 is sealed to the sedimentation tank, so that the powder-containing water treated by the large-volume magnetic absorbing tank 22 can enter the sedimentation tank to precipitate other solid powders. The pore size and arrangement density of the seepage hole should not be too large to ensure that the powder-containing water stays in the large-volume magnetic absorbing tank 22 for a sufficient time to ensure the recovery rate of magnetic powder.

[0047] like Figure 4 As shown, in one technical solution, two small-volume magnetic absorbing pools are provided. Each small-volume magnetic absorbing pool includes a small-volume magnetic absorbing pool body 6 and a connecting pipe 16 disposed at the bottom of the small-volume magnetic absorbing pool body 6. The bottom of the connecting pipe 16 is connected to the bottom of the large-volume magnetic absorbing pool 22 via a flange. The bottom of the connecting pipe 16 is provided with a second seepage hole connecting to the sedimentation tank. The small-volume magnetic absorbing pool and the large-volume magnetic absorbing pool 22 are connected as a whole through the connecting pipe 16, so that when the sedimentation tank is disassembled, the large-volume magnetic absorbing pool 22 and the small-volume magnetic absorbing pool can be disassembled together, and the magnetic powder in the large-volume magnetic absorbing pool 22 and the small-volume magnetic absorbing pool can be recovered at the same time.

[0048] like Figure 4As shown, in one of the technical solutions, any small-volume magnetic absorbing pool body 6 includes an integrally formed cylindrical part 61 and a conical part 62. After the small-volume magnetic absorbing pool body 6 is reduced in diameter, the flow rate of powder-containing water in the small-volume magnetic absorbing pool body 6 can be effectively controlled, ensuring that the powder-containing water stays in the small-volume magnetic absorbing pool body 6 for a sufficient time, and ensuring the recovery rate of magnetic powder.

[0049] like Figure 4 As shown, in one of the technical solutions, a pair of small-volume magnetic absorbing pool bodies 6 are set on a small-volume magnetic absorbing pool base. The bottom of the small-volume magnetic absorbing pool base is provided with a flange connected to the connecting pipe 16. The tapered part 62 of the small-volume magnetic absorbing pool body 6 is set inside the small-volume magnetic absorbing pool base. The setting of the small-volume magnetic absorbing pool base is beneficial to the stability of the small-volume magnetic absorbing pool body 6 and also facilitates the further installation of the second magnetic absorbing structure.

[0050] In one of the technical solutions, the first magnetic attraction structure includes:

[0051] The first motor 13 is mounted on the first motor 13 mounting bracket 10, which is located on the inner edge 23 of the small volume magnetic absorbing pool body 6.

[0052] Multiple first magnetic chucks 5 are connected to the motor shaft 14 of the first motor 13 and rotate with the motor shaft 14 of the first motor 13. The first magnetic chucks 5 are inclined and disposed close to the inner wall of the conical part 62 of the small volume magnetic chuck body 6.

[0053] In the above technical solution, the first magnetic holder 5 includes a first connecting frame connected to the motor shaft 14 of the first motor 13 and a first magnetic strip detachably connected to the first connecting frame. To achieve the detachable connection between the first magnetic strip and the first connecting frame, the first magnetic strip is mounted on a first magnetic strip mounting base. The first magnetic strip mounting base is detachably connected to the first connecting frame. One way to achieve this is that the end of the first connecting frame connected to the first magnetic strip mounting base has a connecting outer edge, and the first magnetic strip mounting base is disposed on the connecting outer edge and fixed with bolts. The installation method of the first magnetic strip mounting base and the first magnetic strip is as follows: the first magnetic strip mounting base has a first magnetic strip engaging groove, and the first magnetic strip is engaged within the engaging groove.

[0054] In the above technical solution, the first magnetic chuck 5 rotates with the motor shaft 14 of the first motor 13, which increases the probability of the first magnetic chuck 5 attracting magnetic powder and fully ensures the recovery rate of magnetic powder.

[0055] In one of the technical solutions, the second magnetic attraction structure includes:

[0056] The second motor 8 is mounted on the base of the small volume magnetic accumulator and the motor shaft 15 of the second motor 8 extends into the large volume magnetic accumulator 22.

[0057] Multiple second magnetic holders 21 are connected to the motor shaft 15 of the second motor 8 and rotate with the motor shaft 15 of the second motor 8. The second magnetic holders 21 are arranged near the bottom of the large volume magnetic pool 22.

[0058] Similarly, in the above technical solution, the second magnetic holder 21 includes a second connecting frame connected to the motor shaft 15 of the second motor 8 and a second magnetic strip detachably connected to the second connecting frame. To achieve the detachable connection between the second magnetic strip and the second connecting frame, the second magnetic strip is mounted on a second magnetic strip mounting base. The second magnetic strip mounting base is detachably connected to the second connecting frame. One way to achieve this is that the end of the second connecting frame connected to the second magnetic strip mounting base has a connecting outer edge, and the second magnetic strip mounting base is disposed on the connecting outer edge and fixed with bolts. The installation method of the second magnetic strip mounting base and the second magnetic strip is as follows: the second magnetic strip mounting base has a second magnetic strip engaging groove, and the second magnetic strip is engaged within the engaging groove.

[0059] In one of the technical solutions, the installation method of the bulk cargo port powdery water treatment device is as follows:

[0060] Step 1: Assemble the magnetic suction component and sedimentation tank of the bulk cargo port powdery water treatment device into a whole in advance;

[0061] Step 2: Design the installation density of the bulk cargo port dust water treatment device according to the different dust water content of each wharf, and install the assembled unit from Step 1 between the wharf pile foundations one by one according to the designed installation density.

[0062] Step 3: According to the installation density in Step 2, design the water collection tank 12 and the number of water collection tanks 12, so that the first guide plate 7 and the second guide plate 9 on the water collection tank 12 correspond to the positions of each small volume magnetic suction pool and the large volume magnetic suction pool 22, and install the water collection tank 12.

[0063] The number of devices and processing capacity described herein are for the purpose of simplifying the description of the invention. Applications, modifications, and variations of the present invention's bulk cargo port powdery water treatment apparatus will be readily apparent to those skilled in the art.

[0064] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
