Description

Technical Field

[0001] This utility model relates to the field of drilling environmental protection equipment technology, and in particular to a device for recycling waste drilling mud from oil and gas fields. Background Technology

[0002] During oilfield drilling, mud pits are excavated near the wellhead. The purpose of the mud pits is to store drilling mud containing waste generated during the drilling process. Since the waste in drilling mud has a significant impact on the environment, it is necessary to treat the drilling mud to reduce pollution.

[0003] A search revealed that utility model patent CN219156714U discloses a device for recycling waste drilling mud from oil and gas fields. The device includes a box-shaped enclosure with a partition that divides the enclosure into a heavy metal purification chamber and a cuttings filtration chamber. The lower part of the heavy metal purification chamber is connected to a mud inlet pipe, and the upper part of the heavy metal purification chamber is connected to the cuttings filtration chamber via a conveying pipe. The inner wall of the heavy metal purification chamber is vertically spaced with several filter plates. The filter plates are perforated and filled with several heavy metal adsorption balls. Each heavy metal adsorption ball includes a perforated outer shell filled with chelating resin balls.

[0004] However, the above-mentioned equipment still has some drawbacks in actual use. The most obvious one is that when recycling heavy metal adsorption balls, the operator needs to first remove the filter plate from the inside of the box, and then open the filter plate and take out the heavy metal adsorption balls from the inside of the filter plate. The operation is cumbersome and too labor-intensive, and it is not convenient in actual use.

[0005] Therefore, it is necessary to invent a device for recycling abandoned drilling mud from oil and gas fields to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a recycling device for waste drilling mud in oil and gas fields, which can more conveniently recover heavy metal adsorption balls. It is easy to operate and saves manpower, and is more convenient to use in practice. This solves the problem mentioned in the background art that when recovering heavy metal adsorption balls, the operator needs to first remove the filter plate from the inside of the box, and then open the filter plate and take out the heavy metal adsorption balls from the inside of the filter plate. This operation is cumbersome and too labor-intensive, and is not convenient to use in practice.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a device for recycling waste drilling mud from oil and gas fields, comprising:

[0008] A drilling mud container, which is used for conveying and containing drilling mud;

[0009] A flow-guiding and regeneration mechanism, wherein the flow-guiding and regeneration mechanism is used to purify and regenerate drilling mud; and

[0010] A heavy metal adsorption ball cleaning mechanism, comprising a side plate, a hydraulic cylinder, an end plate, a column, a push plate, and a guide plate;

[0011] The side plate is fixedly installed on the side of the processing box. The hydraulic cylinder is fixedly installed at the bottom of the side plate and its output shaft passes through the bottom of the side plate and extends to the top of the side plate. The end plate is fixedly installed at the top of the output shaft of the hydraulic cylinder. Multiple columns and push plates are provided. Multiple columns are evenly fixedly installed through the bottom of the end plate. Multiple push plates are respectively fixedly installed at the top of multiple columns and are respectively slidably installed in the vertical direction inside multiple filter barrels. The guide plate is fixedly sleeved on the outside of multiple filter barrels and is inclined.

[0012] According to at least one embodiment of the present disclosure, an oil and gas field waste drilling mud recycling device includes a processing tank and a mud input pipe, wherein the mud input pipe is fixedly disposed at the bottom left side of the processing tank.

[0013] According to at least one embodiment of the oil and gas field waste drilling mud recycling equipment, the drilling mud receiving mechanism further includes a mud output pipe and a delivery pump. The mud output pipe is fixedly installed through the top right side of the processing tank, and the delivery pump is installed on the mud output pipe and fixedly connected to the processing tank.

[0014] According to at least one embodiment of the present disclosure, an oil and gas field waste drilling mud recycling device includes a flow guiding and regeneration mechanism comprising a filter barrel, wherein multiple filter barrels are provided, and the multiple filter barrels are uniformly and fixedly disposed through the top of the processing tank and extend to the bottom of the inner cavity of the processing tank, and the interior of the filter barrel is filled with heavy metal adsorption balls.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a heavy metal adsorption ball cleaning mechanism. When recovering heavy metal adsorption balls from multiple filter barrels, a hydraulic cylinder extends its output shaft, causing an end plate to move upwards via multiple columns and push plates inside the filter barrels. During this upward movement, the push plates displace the stacked heavy metal adsorption balls inside the filter barrels, causing them to overflow from the top opening. The overflowing heavy metal adsorption balls fall into a guide plate and are then continuously discharged through its outlet. Compared to existing similar equipment, this invention offers more convenient heavy metal adsorption ball recovery, is simpler to operate, saves manpower, and is more convenient in practical use.

[0029] Figure 3 This is a schematic diagram of the heavy metal adsorption ball cleaning mechanism 3 of an oil and gas field abandoned drilling mud recycling equipment according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the oil and gas field waste drilling mud recycling equipment disclosed herein may include components such as: drilling mud receiving mechanism 1, flow guiding and regeneration mechanism 2, and heavy metal adsorption ball cleaning mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the drilling mud receiving mechanism 1 includes a processing tank 11, a mud input pipe 12, a mud output pipe 13, and a delivery pump 14. The mud input pipe 12 is fixedly disposed through the bottom left side of the processing tank 11, the mud output pipe 13 is fixedly disposed through the top right side of the processing tank 11, and the delivery pump 14 is disposed on the mud output pipe 13 and fixedly connected to the processing tank 11.

[0032] like Figure 2As shown, in a preferred embodiment, the flow guiding and regeneration mechanism 2 includes a filter barrel 21 and a flow guide plate 22. Multiple filter barrels 21 are provided, and the multiple filter barrels 21 are uniformly and fixedly disposed through the top of the processing box 11 and extend to the bottom of the inner cavity of the processing box 11. The filter barrels 21 are filled with heavy metal adsorption balls. Multiple flow guide plates 22 are provided, and the multiple flow guide plates 22 are fixedly sleeved on the outside of the multiple filter barrels 21 from top to bottom.

[0033] By setting up the drilling mud receiving mechanism 1 and the flow guiding and regeneration mechanism 2, the diluted drilling mud is input into the treatment tank 11 through the mud input pipe 12. After entering the treatment tank 11, the drilling mud passes through the holes on the surface of the filter bucket 21 and comes into contact with the heavy metal adsorption balls inside the filter bucket 21. The heavy metal adsorption balls adsorb and remove heavy metal ions in the drilling mud to achieve the initial regeneration of the drilling mud. The treated drilling mud is output by the delivery pump 14 through the mud output pipe 13.

[0034] like Figure 3 As shown in this disclosure, the heavy metal adsorption ball cleaning mechanism 3 includes a side plate 31, a hydraulic cylinder 32, an end plate 33, a column 34, a push plate 35, and a guide plate 36. The side plate 31 is fixedly disposed on the side of the processing box 11. The hydraulic cylinder 32 is fixedly disposed on the bottom of the side plate 31, and its output shaft passes through the bottom of the side plate 31 and extends to the top of the side plate 31. The end plate 33 is fixedly disposed on the top of the output shaft of the hydraulic cylinder 32. Multiple columns 34 and push plates 35 are provided. Multiple columns 34 are evenly fixedly disposed through the bottom of the end plate 33. Multiple push plates 35 are respectively fixedly disposed on the top of multiple columns 34 and are respectively slidably disposed in the vertical direction inside multiple filter barrels 21. The guide plate 36 is fixedly sleeved on the outside of multiple filter barrels 21 and is inclined.

[0035] Therefore, when recovering the heavy metal adsorption balls inside the multiple filter barrels 21, the hydraulic cylinder 32 drives its output shaft to extend, thereby causing the end plate 33 to drive multiple push plates 35 to continuously move upward inside the multiple filter barrels 21 through multiple columns 34. During the upward movement of the push plates 35, the heavy metal adsorption balls stacked inside the filter barrels 21 are pushed out continuously from the top opening of the filter barrels 21. The overflowing heavy metal adsorption balls continuously fall into the inside of the guide plate 36, and are then continuously output through the discharge port of the guide plate 36. Compared with existing similar equipment, it can recover heavy metal adsorption balls more conveniently, is easy to operate and saves manpower, and is more convenient in actual use.
