Description

Technical Field

[0001] The present invention relates to the field of dock sewage treatment, and more specifically, to a bulk cargo port powder-containing water treatment device. Background Art

[0002] A bulk cargo port refers to a port setting for loading and unloading bulk cargo (such as ore, coal and grain, etc.). The wastewater containing mineral powder particles generated during the loading and unloading of bulk cargo such as ore is powder water. Powder water is inevitably generated during the loading and unloading process at the bulk cargo port terminal. The traditional method is to set up a dock drainage ditch horizontally at the dock (along the width of the dock) and discharge it after treatment with the wastewater in the land drainage pipe. The value of magnetic powder in powder water is high, which is seriously wasted. The existing dock sewage treatment facilities are not only technologically backward, but many dock sewage treatment facilities are even in disrepair. The old docks even lack sewage treatment equipment, which makes it difficult to meet the increasingly stringent environmental protection requirements. The existing dock sewage treatment equipment cannot be installed in combination with the existing conditions of the dock, and needs to occupy the dock operation area. Most docks Sewage treatment equipment cannot recycle high-value magnetic powder. For example, in the utility model patent with announcement number CN208561947U, a sewage treatment equipment for a stone mine wharf is disclosed, including a front cover, a water inlet, an inspection port, a vent, a spiral stirring device, a circulation pipe, a positioning pin, a support column and a support plate. The water inlet is embedded and installed on the surface of the front cover, the vent is arranged parallel to the inspection port, the outer surface of the spiral stirring device is welded to the lower end of the vent, the circulation pipe is fixed to the outer surface of the spiral stirring device by the positioning pin, and the upper surface of the support column is connected to the lower end of the spiral stirring device. By setting a spiral stirring device, the propeller activates the chemical cleaning components in the chemical cleaning layer, so that the sewage is cleaned to the greatest extent, thereby improving the sewage treatment efficiency. It can be seen that the sewage treatment equipment of the above-mentioned stone mine wharf still has the following defects: first, it needs to occupy the operating area of ​​the wharf; second, it cannot recycle high-value magnetic powder.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0018] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0019] like Figures 1 to 4 As shown, the present invention provides a bulk port powder water treatment device, comprising: A sedimentation tank, which is detachably arranged between a pair of pier pile foundations 1, the pair of pier pile foundations 1 are arranged along the extension direction of the pier, the sedimentation tank is arranged above the water surface and a drainage pipe 19 is arranged at the bottom thereof; A magnetic suction component is arranged above the sedimentation tank, comprising a large-volume magnetic suction pool 22 and a small-volume magnetic suction pool arranged in sequence upward from the sedimentation tank, wherein the large-volume magnetic suction pool 22 and the small-volume magnetic suction pool are both configured to be connected to the sedimentation tank and allow a small flow of powder-containing water to pass through, and the small-volume magnetic suction pool and the large-volume magnetic suction pool 22 are both openly arranged and overflow water from the top of the small-volume magnetic suction pool flows into the large-volume magnetic suction pool 22; A water collecting trough 12 is arranged below the dock surface layer 11 along the extension direction of the dock, and the dock surface layer 11 is provided with a drainage hole connected to the water collecting trough 12, and the bottom of the water collecting trough 12 is provided with a first guide plate 7 for guiding water to the small-volume magnetic suction pool, and the side is provided with a second guide plate 9 for guiding water to the large-volume magnetic suction pool 22; The small-volume magnetic attraction pool and the large-volume magnetic attraction pool 22 are respectively provided with a first magnetic attraction structure and a second magnetic attraction structure to absorb magnetic powder in powder-containing water.

[0020] In the above technical solution, if Figure 1 or Figure 2 As shown, the bulk cargo port powder water treatment device is suitable for a wharf whose wharf pile foundation 1 is a supporting pile, such as Figure 1 or Figure 2 As shown, the wharf structure includes wharf pile foundations 1 arranged in sequence along the extension direction of the wharf, a plurality of wharf pile foundations 1 are provided with cross beams 3 along the width direction of the wharf, a plurality of longitudinal beams 4 are arranged on the cross beams 3, and the wharf surface layer 11 is arranged on the longitudinal beams 4. The bulk cargo port powder water treatment device includes a water collecting trough 12, a magnetic suction assembly and a sedimentation tank from top to bottom, wherein the water collecting trough 12 is arranged below the wharf surface layer 11, and a drainage hole connected to the water collecting trough 12 is arranged on the wharf surface layer 11. The powder water (including flushing water) generated during the loading and unloading process of the bulk cargo port flows into the water collecting trough 12 through the drainage hole on the wharf surface layer 11. The water collecting trough 12 is arranged along the extension direction of the wharf. Along the width direction of the wharf, the number of the water collecting troughs 12 corresponds to the number of the sedimentation tanks, that is, according to the actual demand for the discharge of powder water at the wharf, multiple sedimentation tanks can be arranged along the width direction of the wharf, and multiple water collecting troughs 12 should also be arranged corresponding to multiple sedimentation tanks. The water collecting tank 12 can quickly and temporarily store the powder-containing water generated by the dock surface layer 11 in its inner cavity, thereby reducing the water accumulation on the dock surface layer 11 .

[0021] like Figure 3 As shown, in the above technical solution, the magnetic suction component is arranged below the water collecting tank 12, and the powder-containing water in the water collecting tank 12 is gradually guided to the magnetic suction component for processing through the first guide plate 7 and the second guide plate 9. Corresponding to the first guide plate 7 and the second guide plate 9 arranged at different heights, the first guide plate 7 and the second guide plate 9 are respectively provided with a first slot 71 and a second slot 91 at the contact point with the water collecting tank 12. The magnetic suction component includes a small-volume magnetic suction pool and a large-volume magnetic suction pool 22, wherein the small-volume magnetic suction pool is located above the large-volume magnetic suction pool 22, and 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 collecting tank 12 is small, the first guide plate with a lower installation height is installed at a lower height. The guide plate 7 guides a small part of the powder-containing water in the water collection tank 12 to the small volume magnetic suction pool for treatment and then directly enters the sedimentation tank for sedimentation; when the amount of powder-containing water in the water collection tank 12 is large, the first guide plate 7 with a lower installation height guides a small part of the powder-containing water in the water collection tank 12 to the small volume magnetic suction pool for treatment, while the second guide plate 9 with a higher installation height guides the powder-containing water in the water collection tank 12 to the large volume magnetic suction pool 22 for treatment, and then further introduces it into the sedimentation tank for sedimentation. If the powder-containing water in the small volume magnetic suction pool overflows into the large volume magnetic suction pool 22, it will be processed by the large volume magnetic suction pool 22, and the first magnetic suction structure and the second magnetic suction structure are respectively provided in the small volume magnetic suction pool and the large volume magnetic suction pool 22 to absorb the magnetic powder in the powder-containing water. This setting can adapt to the use of docks with different flow rates of powder-containing water, and has strong promotion.

[0022] In the above technical solution, the sedimentation tank is arranged below the magnetic suction component. The powder-containing water treated by the magnetic suction component absorbs most of the magnetic powder and then enters the sedimentation tank to further precipitate other solid powders. The sedimentation tank is detachably connected to the wharf pile foundation 1, and the magnetic powder adsorbed in the small-volume magnetic suction tank and the large-volume magnetic suction tank 22 can be regularly recovered. At the same time, the sediment at the bottom of the sedimentation tank is cleaned regularly. It is easy to use, easy to maintain, and low in cost.

[0023] In one of the technical solutions, the sedimentation tank includes a water level control part 18 and a powder collecting part 20 which are arranged in sequence from top to bottom. The water level control part 18 and the powder collecting part 20 are detachably sealed and connected, and the drain pipe 19 is arranged at the lower part of the water level control part 18. A water level sensor is provided in the water level control part 18, and a control valve is provided on the drain pipe 19. The water level sensor and the control valve are both electrically connected to a controller.

[0024] In the above technical solution, the sedimentation tank is configured with a water level control part 18 and a powder collecting part 20 that can be detachably arranged from top to bottom. The lower powder collecting part 20 can be directly disassembled to clean the sediment at the bottom of the sedimentation tank. Taking into full consideration that the proportion of magnetic powder content in the sediment is relatively low, the magnetic powder recovery cycle and the sediment cleaning cycle are quite different, and only the lower powder collecting part 20 can be disassembled to clean the sediment. When the water level in the sedimentation tank reaches the preset value, the drain pipe 19 is opened to discharge the water after sedimentation in the sedimentation tank into the dock drainage ditch, which can not only ensure the full precipitation of the powder in the sedimentation tank, but also ensure the continuous use of the powder-containing water treatment device, and the treatment efficiency is high. A way to realize the detachable sealed connection between the water level control part 18 and the powder collecting part 20: an ear plate is provided at the connection between the water level control part 18 and the powder collecting part 20, a sealing strip is provided between the two ear plates, and a sealing strip is provided at the contact between the water level control part 18 and the powder collecting part 20.

When the sedimentation tanks are set at a high density, the clamp 17 mounting seats 2 of adjacent sedimentation tanks are staggered in the vertical direction, which is convenient for the installation of the sedimentation tanks.

The large-volume magnetic suction pool 22 is sealed and connected to the sedimentation tank, so that the powder-containing powder treated by the large-volume magnetic suction pool 22 can enter the sedimentation tank to precipitate other solid powders. The aperture and arrangement density of the seepage holes should not be too large to ensure that the powder-containing water stays in the large-volume magnetic suction pool 22 for a sufficient time to ensure the recovery rate of the magnetic powder.

[0027] like Figure 4 As shown, in one of the technical solutions, two small-volume magnetic suction pools are provided, and any small-volume magnetic suction pool includes a small-volume magnetic suction pool body 6 and a connecting pipe 16 arranged at the bottom of the small-volume magnetic suction pool body 6, the bottom of the connecting pipe 16 is connected to the bottom of the large-volume magnetic suction pool 22 through a flange, and a second water seepage hole connected to the sedimentation tank is provided at the bottom of the connecting pipe 16.

The conical portion 62 of the small-volume magnetic pool body 6 is arranged in the small-volume magnetic seat. The setting of the small-volume magnetic pool base is beneficial to the stability of the small-volume magnetic pool body 6, and is also convenient for further installation of the second magnetic structure.

[0032] In the above technical solution, the first magnetic frame 5 rotates with the motor shaft 14 of the first motor 13, which increases the probability of the first magnetic frame 5 attracting magnetic powder and fully ensures the recovery rate of the magnetic powder.
