Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0019] Example like Figures 1 to 7As shown, the present invention provides a port terminal accident wastewater treatment device, including a support frame 1, a centrifugal kettle 2 is rotatably installed in the support frame 1, a first motor 3 for driving the centrifugal kettle 2 to rotate is fixedly installed at the bottom of the support frame 1, a collecting component 4 for collecting wastewater in the centrifugal kettle 2 is fixedly installed at the bottom of the support frame 1, a filter cartridge 21 is fixedly installed in the centrifugal kettle 2, a kettle cover 22 is fixedly installed on the top of the support frame 1, a top plate 23 is fixedly connected to the top of the kettle cover 22, a suction component 5 for collecting oil in the centrifugal kettle 2 is fixedly installed on the kettle cover 22, a water outlet pipe 24 is fixedly installed in the top plate 23, a receiving ring 25 is fixedly connected to the bottom of the water outlet pipe 24, and The receiving ring 25 extends into the filter cartridge 21, and the outer side of the water outlet pipe 24 is slidably connected to the tray 26. The bottom of the top plate 23 is rotatably connected to the screw rod 27 and the adjusting rod 28, and two second motors 29 for driving the screw rod 27 and the adjusting rod 28 to rotate are fixedly installed on the top plate 23. The bottom of the screw rod 27 and the adjusting rod 28 are both rotatably connected to the receiving ring 25. The adjusting rod 28 is slidably connected to the scraper assembly 6 for scraping off the waste on the inner wall of the filter cartridge 21. The bottom of the scraper assembly 6 is provided with a conveying assembly 7 for conveying the waste to the tray 26. The screw rod 27 is used to adjust the horizontal height of the tray 26, and the adjusting rod 28 is used to adjust the rotation angle of the scraper assembly 6. As a further explanation of the embodiment of the present invention, the working principle of the wastewater treatment device in this embodiment is as follows: first, the wastewater to be treated is poured into the top of the outlet pipe 24, and the wastewater enters the filter cartridge 21 along the bottom of the outlet pipe 24. At this time, the first motor 3 is started to drive the centrifugal kettle 2 and the filter cartridge 21 to rotate. The centrifugal force generated by the rotation of the filter cartridge 21 is used to throw the wastewater and debris onto the inner wall of the filter cartridge 21, and the debris remains in the filter cartridge 21. After being filtered by the filter cartridge 21, the wastewater is thrown onto the inner wall of the centrifugal kettle 2 and rotates with the centrifugal kettle 2. Due to the action of centrifugal force, the oil and water in the wastewater will be separated into different layers, and the water with higher density will settle to the bottom, while the oil with lower density will float on the top. The wastewater settled at the bottom of the centrifugal kettle 2 is collected by the collecting component 4, and the oil floating on the top of the centrifugal kettle 2 is extracted by the suction component 5, so as to realize the classified treatment of the wastewater.

[0020] In addition, when too much debris attached to the inner wall of the filter cartridge 21 causes the filter holes to be blocked and affects the subsequent filtering process, the scraper assembly 6 is driven to rotate to a preset angle through the adjustment rod 28, so that the scraper assembly 6 fits the inner wall of the filter cartridge 21 and scrapes off the debris attached to the filter cartridge 21, and then cooperates with the conveying assembly 7 to convey the scraped debris into the tray 26, and the horizontal height of the tray 26 is adjusted by the second motor 29, so that the tray 26 carrying the debris is sent out from the top of the centrifugal reactor 2, and the debris on the tray 26 is collected and processed in time, and then the tray 26 is reset, so that the wastewater classification and treatment process can be carried out continuously and efficiently.

[0021] As a further embodiment of a port terminal accident wastewater treatment device, the scraper assembly 6 includes a sleeve 61 slidably mounted on the adjusting rod 28, an extension plate 62 is fixedly connected to one side of the sleeve 61, a scraper plate 63 is installed at one end of the extension plate 62 away from the sleeve 61, and the front end of the scraper plate 63 is in contact with the inner wall of the filter cartridge 21.

[0022] As a further embodiment of a port terminal accident wastewater treatment device, the conveying assembly 7 includes a supporting trough plate 71 fixedly installed on the side wall of the scraper plate 63, and a conveying ladder 72 is fixedly installed on the side wall of the extension plate 62, and the conveying ladder 72 and the supporting trough plate 71 cooperate with each other to transport the waste scraped from the scraper plate 63 to the tray 26.

[0023] As a further embodiment of a port terminal accident wastewater treatment device, the scraper plate 63 and the extension plate 62 are hinged to each other through a hinge rod 64, and a double torsion spring 65 is sleeved on the outside of the hinge rod 64, and the two ends of the double torsion spring 65 are respectively pressed against the side walls of the extension plate 62 and the side walls of the scraper plate 63.

[0024] As a further illustration of the embodiment of the present invention, in the present embodiment, the centrifugal kettle 2 and the filter cartridge 21 rotate in a clockwise direction with the axis of the centrifugal kettle 2 as the center, so the scraper plate 63 and the extension plate 62 are hinged to each other, so that the scraper plate 63 can rotate along the axial direction of the hinge rod 64, but a double torsion spring 65 is arranged on the back of the scraper plate 63, and the resistance force provided by the double torsion spring 65 can limit the rotation angle of the scraper plate 63, so that the scraper plate 63 can only rotate in the counterclockwise direction along the axial direction of the hinge rod 64. At the same time, after the scraper plate 63 rotates to a preset angle, it will make The supporting groove plate 71 and the conveying ladder 72 are in conflict with each other, so that the scraper plate 63 maintains a state of being in contact with the inner wall of the filter cartridge 21, and the centrifugal force generated by the rotating filter cartridge 21 throws the debris onto the inner wall of the filter cartridge 21. When the debris rotates in the clockwise direction with the filter cartridge 21, the scraper plate 63 scrapes the debris off and is impacted by various debris, causing the scraper plate 63 to rotate in the clockwise direction and compress the double torsion spring 65. The deformation of the double torsion spring 65 can alleviate the impact of the scraper plate 63, so that the scraper plate 63 will not damage the inner wall of the filter cartridge 21 while scraping the debris.

[0025] Furthermore, in the present embodiment, the elastic force generated by the deformation of the double torsion spring 65 resets the scraper plate 63. During the resetting process of the scraper plate 63, the supporting groove plate 71 quickly approaches the conveyor ladder 72 as the scraper plate 63 resets, and collides with the conveyor ladder 72. During the collision, the conveyor ladder 72 and the supporting groove plate 71 vibrate. Such vibration can transfer the debris scraped off by the scraper plate 63 to the position of the tray 26, and prevent the debris from sticking to the conveyor ladder 72 and the supporting groove plate 71.

[0026] As a further embodiment of a port terminal accident wastewater treatment device, a limiting groove 281 is provided in the adjusting rod 28 , and a protrusion 611 for extending into the limiting groove 281 is fixedly installed in the sliding sleeve 61 .

[0027] As a further explanation of the embodiment of the present invention, in this embodiment, while the scraper plate 63 scrapes off the debris, some debris that is not fully dehydrated may also be scraped off by the scraper plate 63. To ensure that the oily substances and wastewater attached to the debris are fully separated, the second motor 29 drives the adjusting rod 28 to drive the sliding sleeve 61 to rotate to a preset angle. Only then can the scraper plate 63 fit against the inner wall of the filter cartridge 21, so that the debris attached to the filter cartridge 21 has sufficient time to be dehydrated.

[0028] As a further embodiment of a port terminal accident wastewater treatment device, the outside of the outlet pipe 24 is slidably connected to a cover 241, and the cover 241 is used to seal the top of the kettle cover 22. The outside of the outlet pipe 24 is sleeved with a spring 242, and the two ends of the spring 242 are respectively pressed against the bottom of the top plate 23 and the top of the cover 241.

[0029] As a further illustration of the embodiment of the present invention, in this embodiment, by providing a sealing cover 241 , the centrifugal kettle 2 is in a relatively sealed environment when in operation, thereby preventing waste water from flying out or other debris from flying into the centrifugal kettle 2 .

[0030] As a further embodiment of a port terminal accident wastewater treatment device, the collecting assembly 4 includes a water collecting ring 41 fixedly installed on the bottom of the support frame 1, and the top of the water collecting ring 41 is in contact with the bottom of the centrifuge kettle 2. A plurality of water outlet holes 43 are provided at the bottom of the centrifuge kettle 2, and a water pump 42 is fixedly connected to one side of the water collecting ring 41.

[0031] As a further embodiment of a port terminal accident wastewater treatment device, the suction assembly 5 includes a channel tube 51 fixedly installed on the kettle cover 22, a telescopic tube is installed in the channel tube 51, one end of the telescopic tube extends into the centrifugal kettle 2, and the other end is connected to a pump (the telescopic tube and pump in this embodiment are not shown in the figure).
