Description

Technical Field

[0001] This utility model belongs to the field of oil sludge technology in oil depots, and specifically relates to an oil sludge separation device for oil depots. Background Technology

[0002] Currently, tank cleaning operations are common in oil depots, generating large quantities of oil sludge mixtures. These mixtures contain sludge, iron filings, water, and oil, and are typically disposed of by hazardous waste companies. Because only the solid portion of the sludge is considered hazardous waste, with a liquid content exceeding 90%, the disposal costs for these mixtures are relatively high.

[0003] A search revealed that patent CN220376552U discloses an oil sludge separation device for an oil depot, comprising: a support frame with a recovery chamber, a screen with a separation chamber, the separation chamber being connected to the recovery chamber, the screen being rotatably mounted on the support frame around a first axis, multiple baffles being spaced apart along the circumference of the separation chamber, the baffles extending along the first axis, and the baffles having through holes along a second axis, adjacent baffles being connected by a guide plate, and a feed pipe being connected to the separation chamber, the first axis being perpendicular to the second axis. Its advantages are: the baffles can guide the liquid and break its suspension, facilitating the separation of the solid and liquid components of the oil sludge mixture; the guide plate can guide the oil sludge mixture to rotate fully within the screen, allowing the liquid component of the oil sludge mixture to enter the recovery chamber through the separation chamber, thereby reducing the weight of the oil sludge mixture and lowering disposal costs.

[0004] However, in actual use, the above-mentioned existing technology has been found to have low processing efficiency, high energy consumption, and difficulty in discharging the separated oil sludge solids, requiring multiple cleanings of the tank, which is too cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil sludge separation device for oil depots.

[0006] To achieve the above objectives, this utility model provides an oil sludge separation device for oil depots, including a coating box, a base fixedly connected to the bottom of the coating box, a separation tank rotatably installed inside the coating box, a meshing part fixedly connected to one side of the separation tank, a driving mechanism provided inside the base, and the driving mechanism drives the separation tank to rotate inside the base through the meshing part, and a liquid collection assembly provided outside the separation tank.

[0007] In the above technical solution, the separation tank is further provided with uniformly distributed connecting plates, and a guide plate is fixedly connected to the top of the connecting plates, and the guide plate is set to an inclined state.

[0008] In the above technical solution, the separating tank further includes a concave portion and a protruding portion that are cross-connected, and a connecting plate is fixedly connected to the outer wall of the protruding portion and the concave portion. A connecting portion is fixedly connected between the protruding portion and the engaging portion near the engaging portion. A mounting seat is rotatably installed at the bottom of the concave portion and is fixedly connected to the base. A filter frame is fixedly installed on the protruding portion.

[0009] In the above technical solution, the protrusion is further provided with uniformly distributed cutting plates, and the cutting plates are set in an inclined state.

[0010] In the above technical solution, the liquid collection assembly further includes a collection bucket rotatably connected to the outer wall of the protrusion via a slide rail. The top of the collection bucket is fixedly connected to a water inlet, which penetrates and extends through the covering box to the top of the covering box. The bottom of the collection bucket is fixedly connected to a water storage part, which penetrates and extends through the covering box to the bottom of the covering box. A water storage tank is fixedly installed inside the base and is connected to the water storage part. The bottom of the water storage tank is fixedly connected to a water outlet pipe.

[0011] In the above technical solution, the collection bucket is further provided with uniformly distributed partitions, and liquid holes are provided on the partitions.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The drive mechanism drives the separation tank to rotate forward, and the guide plate will continuously tumble the oil sludge mixture inside the separation tank, improving the mixing efficiency. After the separation tank is reversed, the inclined guide plate will slide out of the separation tank along the inclined surface after tumbling the oil sludge mixture, completing the automatic discharge of materials. With the above design, the discharge efficiency is greatly improved and the discharge time is reduced by taking advantage of the material's gravity flow and the angle of the plate. This improves production efficiency, effectively solves the problem of material residue, and also reduces the burden of subsequent cleaning work.

[0014] The protrusions and concave sections are distributed in an alternating manner. After the material is flipped by the guide plate, it will be concentrated inside the protrusion and cut by the cutting plate inside the protrusion. The inclined cutting plate can promote the more even distribution of the material in the tank when cutting the material, reduce the accumulation and resistance of the oil sludge mixture, improve the separation effect, and reduce energy consumption to a certain extent.

[0015] The collection bucket is designed to correspond to the filter frame and can hold the liquid separated from the filter frame. By setting a baffle, the baffle forms a barrier inside the collection bucket, which can extend the flow time of the liquid used for cleaning and improve cleaning efficiency. By setting a liquid hole, the flow rate of water when the collection bucket is full can be increased, further improving cleaning efficiency. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-5The illustrated oil sludge separation device for an oil depot includes a covering box 2, a base 1 fixedly connected to the bottom of the covering box 2, a separation tank 4 rotatably installed inside the covering box 2, a meshing part 5 fixedly connected to one side of the separation tank 4, a driving mechanism 3 installed inside the base 1, and the driving mechanism 3 drives the separation tank 4 to rotate inside the base 1 through the meshing part 5, a liquid collection assembly installed outside the separation tank 4, and evenly distributed connecting plates 12 fixedly connected inside the separation tank 4, with a guide plate 11 fixedly connected to the top of the connecting plates 12. The guide plate 11 is set in an inclined state. The driving mechanism 3 drives the separation tank 4 to rotate forward, and the guide plate 11 will continuously tumble the oil sludge mixture inside the separation tank 4, improving the mixing efficiency. After the separation tank 4 is driven to rotate in reverse, the inclined guide plate 11 will slide out of the separation tank 4 along the inclined surface after tumbling the oil sludge mixture, completing the automatic discharge of the material. With the above design, the discharge efficiency is greatly improved and the discharge time is reduced by utilizing the self-flow of the material and the angle advantage of the plate, thus improving production efficiency, effectively solving the problem of material residue, and also reducing the burden of subsequent cleaning work.

[0024] The separator 4 includes a concave portion 8 and a protruding portion 7 that are cross-connected. A connecting plate 12 is fixedly connected to the outer wall of the protruding portion 7 and the concave portion 8. A connecting portion 6 is fixedly connected between the protruding portion 7 and the meshing portion 5. A mounting base 15 is rotatably installed at the bottom of the concave portion 8 and is fixedly connected to the base 1. A filter frame 9 is fixedly installed on the protruding portion 7. A uniformly distributed cutting plate 10 is fixedly connected inside the protruding portion 7 and is set in an inclined state. The protruding portion 7 and the concave portion 8 are cross-distributed. After the material is flipped by the guide plate 11, it will be concentrated inside the protruding portion 7 and cut by the cutting plate 10 inside the protruding portion 7. When the inclined cutting plate 10 cuts the material, it can promote the material to be more evenly distributed in the tank, reduce the accumulation and resistance of the oil sludge mixture, improve the separation effect, and reduce energy consumption to a certain extent.

[0025] The liquid collection assembly includes a collection bucket 13 rotatably connected to the outer wall of the protrusion 7 via a slide rail 16. The top of the collection bucket 13 is fixedly connected to a water inlet 14, which penetrates and extends above the covering box 2. The bottom of the collection bucket 13 is fixedly connected to a water storage section 18, which also penetrates and extends to the bottom of the covering box 2. A water storage tank 19 is fixedly installed inside the base 1 and is connected to the water storage section 18. A water outlet pipe 20 is fixedly connected to the bottom of the water storage tank 19. Evenly distributed partitions 17 are fixedly connected inside the collection bucket 13. The plate 17 has liquid holes, and the collection tank 13 is set to correspond to the filter frame 9. It can hold the liquid separated from the filter frame 9. By setting the partition 17, the partition 17 forms a blockage inside the collection tank 13, which can extend the flow time of the liquid used for cleaning and improve the cleaning efficiency. By setting the liquid holes, the flow rate of water when the collection tank 13 is full can be increased, further improving the cleaning efficiency. It should be noted that the filter frame 9 is set in the half of the base 1. When injecting cleaning water into the collection tank 13, in order to ensure that the water can flow in the collection tank 13, the side without the filter frame 9 should face upward.

[0026] Working principle:

[0027] The drive mechanism 3 drives the separation tank 4 to rotate forward. The guide plate 11 will continuously tumble the oil sludge mixture inside the separation tank 4, improving the mixing efficiency. After the separation tank 4 is reversed, the inclined guide plate 11 will slide out of the separation tank 4 along the inclined surface after tumbling the oil sludge mixture, completing the automatic discharge of materials. With the above design, the discharge efficiency is greatly improved by utilizing the self-flow of materials and the angle advantage of the plate, reducing the discharge time, improving production efficiency, effectively solving the problem of material residue, and also reducing the burden of subsequent cleaning work.

[0028] The protrusions 7 and the recesses 8 are distributed in an intersecting manner. After the material is flipped by the guide plate 11, it will be concentrated inside the protrusions 7 and cut by the cutting plate 10 inside the protrusions 7. The inclined cutting plate 10 can promote the material to be more evenly distributed in the tank when cutting the material, reduce the accumulation and resistance of the oil sludge mixture, improve the separation effect, and reduce energy consumption to a certain extent.

[0029] The collection bucket 13 is configured to correspond to the filter frame 9 and can hold the liquid separated from the filter frame 9. By setting the baffle 17, the baffle 17 forms a barrier inside the collection bucket 13, which can extend the flow time of the liquid used for cleaning and improve the cleaning efficiency. By setting the liquid hole, the flow speed of water when the collection bucket 13 is full can be increased, further improving the cleaning efficiency.
