Description

Technical Field

[0001] This utility model relates to the field of grease treatment technology, and in particular to a device for separating and treating grease from ship kitchen wastewater. Background Technology

[0002] As an important carrier for maritime transportation and operations, ships generate a large amount of oily wastewater in their kitchens during daily operations. This wastewater is characterized by large volume, high concentration of suspended solids and pollutants, and requires treatment.

[0003] Therefore, the existing technology of a slaughterhouse wastewater grease separation and recovery device, publication number: CN220976763U, involves the operator first pumping the wastewater, after being treated by a screen, into an grease adsorption tank, adding hydrophobic microspheres to the grease adsorption tank, and using an air pump for aeration and stirring to ensure that the hydrophobic microspheres completely adsorb the grease. After adsorption is complete, stirring is stopped, and a rotating support is rotated via a rotating shaft to bring the magnet above the grease adsorption tank. Then, an electric winch is turned on, and a wire rope carrying the magnet is brought into the grease adsorption tank. The magnet is energized using a magnet controller to generate magnetism, and the magnet is placed into the grease adsorption tank through the rotating support. The magnet adsorbs the hydrophobic microspheres, and then the rotating support places the magnet with the adsorbed hydrophobic microspheres above a centrifuge. Finally, the magnet controller is de-energized, the magnetism disappears, and the hydrophobic microspheres enter the centrifuge.

[0004] However, while the device uses magnets to recycle magnetic oil-absorbing materials, the magnets have a limited adsorption range in practical applications, making it difficult to fully contact and adsorb the dispersed magnetic adsorbent materials in the pool. This results in some material residue, affecting the oil recovery effect and causing the device to be inefficient. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a device for separating and treating oily wastewater from ship kitchens.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a marine kitchen wastewater grease separation and treatment device, comprising a grease adsorption chamber and a centrifuge, and a support base for fixing the grease adsorption chamber and the centrifuge. A connecting pipe is provided between the grease adsorption chamber and the centrifuge. A lead screw is rotatably connected to the top of the support base. A slider that is slidably connected to the support base is externally threaded to the lead screw. A rack is slidably connected to one side of the slider. An installation rod is fixedly connected to the bottom end of the rack. A drainage hopper fixed to the installation rod is provided inside the grease adsorption chamber. A water leakage plate is provided at the bottom end of the drainage hopper. Four connecting rods arranged in a circular array are fixedly connected to the bottom of the water leakage plate. The connecting rods are slidably connected to the drainage hopper, and a connecting ring is fixedly connected to the bottom end of the four connecting rods. A stop bar located above the inlet end of the centrifuge is fixedly connected to one side of the support base.

[0007] Preferably, a water tank is fixedly installed on the outside of the support base, and the water tank is connected to the centrifuge through a pipe.

[0008] Preferably, an expansion plate is fixedly connected to the outer side of the centrifuge inlet end, and a filter plate is provided at the centrifuge outlet end.

[0009] Preferably, the connecting pipe is equipped with an electric valve.

[0010] Preferably, a motor is fixedly connected to one side of the support base, and the motor spindle is fixed to the lead screw.

[0011] Preferably, a motor is also fixedly connected to one side of the slider, and the motor spindle located on one side of the slider is fixedly connected to a gear that meshes with a rack, and the gear is rotatably connected to the slider.

[0012] Preferably, the bottom of the grease adsorption chamber is provided with a drain outlet.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a support base, lead screw, slider, rack, drainage hopper, water leakage plate, connecting rod, connecting ring and stop bar, etc., the hydrophobic microspheres can be efficiently transferred between the oil adsorption chamber and the centrifuge. When it is necessary to transfer the hydrophobic microspheres, the rack drives the drainage hopper to rise above the oil adsorption chamber, the lead screw drives the slider to slide above the centrifuge, and then the rack drives the drainage hopper to move down. After the connecting ring and the stop bar are engaged, the drainage hopper continues to move down, causing the water leakage plate to be raised, and the hydrophobic microspheres can then fall smoothly into the centrifuge for subsequent processing.

[0015] 2. In this utility model, by setting up components such as a water tank, connecting pipe and electric valve, the hydrophobic microspheres are recycled. The water tank can supply water to the centrifuge. Under the control of the electric valve, the water can carry the hydrophobic microspheres separated by the centrifuge back to the oil adsorption chamber through the connecting pipe, so as to realize the reuse of the hydrophobic microspheres.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a marine kitchen wastewater grease separation and treatment device includes a grease adsorption chamber 2 and a centrifuge 11, and a support base 1 for fixing the grease adsorption chamber 2 and the centrifuge 11. A connecting pipe 4 is provided between the grease adsorption chamber 2 and the centrifuge 11. A lead screw 18 is rotatably connected to the top of the support base 1. A slider 15 is threadedly connected to the outside of the lead screw 18 and slidably connected to the support base 1. A rack 13 is slidably connected to one side of the slider 15. An installation rod 6 is fixedly connected to the bottom end of the rack 13. A drainage hopper 3 is provided inside the grease adsorption chamber 2 and fixed to the installation rod 6. A drain plate 14 is provided at the bottom end of the drainage hopper 3. Four connecting rods 16 arranged in a circular array are fixedly connected to the bottom of the drain plate 14. The connecting rods 16 are slidably connected to the drainage hopper 3, and the bottom ends of the four connecting rods 16 are fixedly connected to connecting rings 19. A baffle 10 located above the inlet end of the centrifuge 11 is fixedly connected to one side of the support base 1.

[0024] In this technical solution, the support base 1 provides a stable installation foundation for the entire device, ensuring the stable placement of components such as the grease adsorption chamber 2 and the centrifuge 11. The grease adsorption chamber 2 is used for preliminary adsorption treatment of grease in ship kitchen wastewater. When hydrophobic microspheres are added to the grease adsorption chamber 2 through the drainage hopper 3, they will fall into the drainage hopper 3. Through the rack 13, the upward movement of the rack 13 drives the drainage hopper 3 to move upward, thereby moving the drainage hopper 3 above the grease adsorption chamber 2. Through the lead screw 18 and the slider 15, when the lead screw 18 rotates, it drives the slider 15 to slide, and it continues to slide above the centrifuge 11 and then stops. At this time, the rack 13 moves downward, driving the drainage hopper 3 downward, so that the connecting ring 19 overlaps with the stop bar 10. The drainage hopper 3 continues to move downward, so that the drainage hopper 3 moves relative to the connecting ring 19, the connecting rod 16 and the drain plate 14. At this time, the drain plate 14 is lifted in the drainage hopper 3, so that the hydrophobic microspheres roll downward through the gap between the adjacent connecting rods 16 and fall into the centrifuge 11.

[0025] In addition, by setting the connecting pipe 4, after the hydrophobic microspheres and grease are separated in the centrifuge 11, the grease is discharged from the outlet end of the centrifuge 11, while the hydrophobic microspheres roll back into the grease adsorption chamber 2 through the connecting pipe 4 to complete the cycle.

[0026] like Figure 2 As shown, a water tank 5 is fixedly installed on the outside of the support base 1, and the water tank 5 is connected to the centrifuge 11 through a pipe.

[0027] In this technical solution, by setting up a water tank 5, after the centrifuge 11 discharges the grease, the water tank 5 supplies water to the centrifuge 11, so that the water flows into the grease adsorption chamber 2 through the connecting pipe 4, thereby driving the hydrophobic microspheres to move together.

[0028] like Figure 1 As shown, an expansion plate 7 is fixedly connected to the outside of the inlet end of the centrifuge 11, a filter plate 20 is provided at the outlet end of the centrifuge 11, and an electric valve 8 is provided on the connecting pipe 4.

[0029] In this technical solution, the expansion plate 7 is fixed on the outside of the inlet end of the centrifuge 11. Its expansion structure can expand the receiving range of the inlet end of the centrifuge 11, making it easier for the material or liquid that has been adsorbed with grease transferred from the grease adsorption chamber 2 to enter the interior of the centrifuge 11.

[0030] The filter plate 20 installed at the outlet end of the centrifuge 11 can hold hydrophobic microspheres that are discharged together with the grease. The opening and closing of the connecting pipe 4 can be controlled by the electric valve 8. By adjusting the opening and closing state of the electric valve 8, the real-time mechanism for the centrifuge 11 to deliver hydrophobic microspheres to the grease adsorption chamber 2 can be flexibly controlled.

[0031] like Figure 1 and Figure 4As shown, a motor 9 is fixedly connected to one side of the support base 1. The main shaft of the motor 9 is fixed to the lead screw 18. A motor 9 is also fixedly connected to one side of the slider 15. The main shaft of the motor 9 located on the side of the slider 15 is fixedly connected to a gear 17 that meshes with the rack 13. The gear 17 is rotatably connected to the slider 15.

[0032] In this technical solution, a motor 9 fixed on one side of the support base 1 serves as the power source, with its main shaft fixedly connected to the lead screw 18. When the motor 9 starts, it can directly drive the lead screw 18 to rotate. A motor 9 fixed on one side of the slider 15 provides power for the movement of the rack 13. The main shaft of this motor 9 is fixed to a gear 17, which meshes with the rack 13 and is rotatably connected to the slider 15. When this motor 9 starts, it drives the gear 17 to rotate. Through the meshing transmission between the gear 17 and the rack 13, the rotation of the gear 17 is converted into the up-and-down sliding of the rack 13.

[0033] like Figure 1 As shown, the bottom of the grease adsorption chamber 2 is provided with a drain outlet 12.

[0034] The method of using this utility model is as follows: Hydrophobic microspheres are added to the grease adsorption chamber 2. The microspheres fall into the drainage hopper 3 and adsorb the grease in the wastewater. Then, the motor 9 on one side of the slider 15 starts, driving the gear 17 to rotate. This gear 17 meshes with the rack 13, causing the rack 13 to move upwards, thereby raising the drainage hopper 3 above the grease adsorption chamber 2. The motor 9 on one side of the support base 1 starts, driving the lead screw 18 to rotate, causing the slider 15 to slide above the centrifuge 11 and then stop. Then, the slider 15... The motor 9 rotates in reverse, and the rack 13 moves downward, causing the drain bucket 3 to move down. After the connecting ring 19 overlaps with the stop bar 10, the drain bucket 3 continues to move down, the drain plate 14 is raised, and the hydrophobic microspheres fall into the centrifuge 11 through the gap between the adjacent connecting rods 16. The outer expansion plate 7 assists in receiving them. The centrifuge 11 works to separate the grease and the hydrophobic microspheres. The filter plate 20 prevents the hydrophobic microspheres from being discharged with the grease. After separation, the water tank 5 supplies water, the electric valve 8 is opened, and the water carrying the hydrophobic microspheres flows back to the grease adsorption chamber 2 through the connecting pipe 4, completing the cycle.

[0035] The wiring diagrams of the electric valve 8, motor 9, and centrifuge 11 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric valve 8, motor 9, and centrifuge 11 will not be explained in detail.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
