Description

Technical Field

[0001] This utility model relates to the field of oily waste treatment technology, and in particular to a separation and filtration device for oily waste treatment. Background Technology

[0002] Oily waste is solid waste generated during oilfield production. It is a special type of oily solid waste formed during well operations by mixing crude oil, wastewater, surface soil, and waste steel slag used to cover the well site. Oily waste cannot be discarded directly; it must be separated from the crude oil using a separation and filtration device before the remaining solids can be processed.

[0003] However, existing oily waste separation and filtration devices typically only pour oily waste into the filter barrel and then use the filter holes on the surface of the filter barrel for simple static treatment to separate the oil from the surface soil and waste steel slag. The lack of external force to drive the filter barrel results in low separation and filtration efficiency due to static separation alone, which affects subsequent production. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a separation and filtration device for treating oily waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A separation and filtration device for treating oily waste includes:

[0007] A right-angle frame and a separation tank fixedly installed inside the right-angle frame;

[0008] The filtration and separation assembly includes a rotating disk rotatably mounted on the top of a separation tank. A drive bar is fixedly mounted on the bottom of the rotating disk. A drive motor for driving the rotating disk to rotate is fixedly mounted on the top of the separation tank. A hemispherical shell is pressed against the outer surface of the separation tank. An oil outlet pipe is fixedly connected to the bottom of the hemispherical shell. A filter barrel is provided inside the hemispherical shell through a support assembly. The filter barrel extends movably into the separation tank. Multiple protrusions are fixedly mounted on the top of the filter barrel.

[0009] The lifting assembly is used to control the vertical movement of the hemispherical shell.

[0010] Preferably, the lifting assembly includes a lead screw rotatably mounted on the outside of the right-angle frame, a connecting plate threaded onto the surface of the lead screw, and the connecting plate movably passes through the outside of the right-angle frame and is fixed to the hemispherical shell. A lifting motor for driving the lead screw to rotate is fixedly mounted on the top of the right-angle frame.

[0011] Preferably, the support assembly includes a fixing ring fixedly installed on the surface of the filter barrel, the bottom of the fixing ring contacting a support ring, the support ring being fixedly installed inside the hemispherical shell by multiple support rods, and the support ring being slidably sleeved on the surface of the filter barrel.

[0012] Preferably, the surface of the right-angle frame has a through hole, and the through hole is slidably connected to the connecting plate.

[0013] Preferably, a limiting strip is fixedly installed on the surface of the right-angle frame, and the limiting strip is positioned above the connecting plate.

[0014] Compared with existing technologies, the advantages of the separation and filtration device for treating oily waste provided by this utility model are as follows:

[0015] 1. By pushing the protrusions with the drive bar, the filter barrel can be driven to rotate at high speed when the drive motor controls the rotating disk to rotate, thereby achieving the effect of high-speed centrifugal separation and filtration of oily waste in the filter barrel, and improving the centrifugal filtration efficiency of oily waste.

[0016] 2. The lifting motor controls the rotation of the lead screw, which can realize the lifting and lowering of the hemispherical shell, making it convenient to put the filter canister in and out before and after separating and filtering oily waste.

[0017] This invention utilizes a hemispherical shell that can be raised and lowered. After the shell is moved upward, the filter barrel is moved into the separation tank. Under the control of the drive motor, the filter barrel is rotated at high speed, thereby achieving the effect of high-speed centrifugal separation and filtration of oily waste in the filter barrel, thus improving the centrifugal filtration efficiency of oily waste.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 4 A separation and filtration device for treating oily waste, comprising:

[0025] Right-angle frame 1 and separation tank 2 fixedly installed inside the right-angle frame 1.

[0026] The filtration and separation assembly includes a rotating disk 3 rotatably mounted on the top of the separation tank 2, a drive bar 4 fixedly mounted on the bottom of the rotating disk 3, a drive motor 5 fixedly mounted on the top of the separation tank 2 for driving the rotating disk 3 to rotate, a hemispherical shell 6 pressed against the outer surface of the separation tank 2, an oil outlet pipe fixedly connected to the bottom of the hemispherical shell 6, and a valve installed on the oil outlet pipe (not described in detail in the figure, this is existing public technology).

[0027] Furthermore, a filter bucket 7 is provided inside the hemispherical shell 6 via a support assembly. The support assembly includes a fixing ring 12 fixedly installed on the surface of the filter bucket 7. The bottom of the fixing ring 12 contacts a support ring 13. The support ring 13 is fixedly installed inside the hemispherical shell 6 via multiple support rods 14. The support ring 13 is slidably sleeved on the surface of the filter bucket 7, which plays a supporting role for the filter bucket 7, allowing the filter bucket 7 to be suspended in the air inside the separation tank 2 and the hemispherical shell 6, and also facilitating the removal and placement of the filter bucket 7.

[0028] Furthermore, the filter barrel 7 extends into the separation tank 2. Multiple protrusions 8 are fixedly installed on the top of the filter barrel 7. After the filter barrel 7 is moved into the separation tank 2, the protrusions 8 will come into contact with the rotating disk 3. Thus, when the drive motor 5 controls the rotating disk 3 to rotate, the filter barrel 7 can rotate by pushing the protrusions 8.

[0029] A lifting assembly is used to control the vertical movement of the hemispherical shell 6. The lifting assembly includes a lead screw 10 rotatably mounted on the outside of the right-angle frame 1. A connecting plate 9 is threadedly connected to the surface of the lead screw 10, and the connecting plate 9 movably passes through the outside of the right-angle frame 1 and is fixed to the hemispherical shell 6. A through hole 15 is opened on the surface of the right-angle frame 1, and the through hole 15 is slidably connected to the connecting plate 9. A lifting motor 11 for driving the lead screw 10 to rotate is fixedly installed on the top of the right-angle frame 1. When the lifting motor 11 is started to control the lead screw 10 to rotate, the hemispherical shell 6 can be driven to move vertically through the limiting position of the connecting plate 9 and the through hole 15.

[0030] Furthermore, a limiting strip 16 is fixedly installed on the surface of the right-angle frame 1, and the limiting strip 16 is positioned above the connecting plate 9. It can limit the movement of the connecting plate 9 when it moves upward. When the connecting plate 9 contacts the limiting strip 16, the protrusion 8 just contacts the rotating disk 3 instead of being tightly pressed against it. This can effectively prevent the rotating disk 3 from pressing the fixing ring 12 on the filter barrel 7 against the support ring 13, thus preventing the filter barrel 7 from being unable to rotate.

[0031] The working principle of this utility model is as follows:

[0032] When in use, first pour the oily waste into the filter bucket 7, then control the screw 10 to rotate through the lifting motor 11, drive the connecting plate 9 to move up until the hemispherical shell 6 is pressed against the bottom of the separator tank 2, then place the oil receiving container on the right angle frame 1 and place it below the oil drain pipe, and then open the valve.

[0033] Then, start the drive motor 5 to control the rotating disk 3 to rotate. Use the drive bar 4 to push the protrusion 8 to make the filter barrel 7 rotate, so as to achieve the effect of high-speed centrifugal separation and filtration of oily waste in the filter barrel 7. Finally, the oil in the oily waste is thrown out of the filter barrel 7 and flows into the separation tank 2 and the hemispherical shell 6. The oil in the oily waste can then flow into the container through the oil drain pipe for collection.

[0034] Finally, after centrifugal separation and filtration, the lifting motor 11 controls the lead screw 10 to reverse, causing the connecting plate 9 to move the hemispherical shell 6 downwards. Then, the filter bucket 7 can be taken out and the waste inside can be poured out.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
