Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-based sludge technology, specifically to a drilling oil-based sludge treatment device. Background Technology
[0002] Oil-based sludge generally refers to a hazardous waste generated during the drilling process of oil and gas resource exploration and exploitation. Its source is oil-based drilling cuttings generated from the oil-based mud used in offshore drilling platforms and inland oil and gas fields during drilling, well completion, well repair, fracturing and other operations.
[0003] Existing methods for treating oil-based sludge typically employ high-efficiency solidification. This method uses solidifying agents to transform the sludge into a more stable, easier-to-handle, and more manageable solid form. Concrete is usually used as the solidification substrate. During solidification, a mixing rod is installed at the end of an excavator's boom. The boom drives the mixing rod to mix the sludge on-site, adding concrete as it mixes, thus achieving solidification. However, in practice, the mixing rod's direction is relatively unidirectional. It can only simply break up and disrupt the oil-based sludge accumulated on the ground, making it difficult to mix the concrete with the sludge. This results in the mixing rod needing to remain in the same spot for an extended period, repeatedly breaking up and mixing the sludge, leading to low mixing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a drilling oil-based sludge treatment device to address the aforementioned shortcomings in the technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A drilling oil-based sludge treatment device includes a fixed base, a connecting rod fixed to the top of the fixed base, and a stirring rod assembly provided on the outer wall of the fixed base. The stirring rod assembly includes two first supports and a second support provided on the outer wall of the fixed base. Each of the two first supports is provided with a main stirring rod, and the second support is provided with a secondary stirring rod. The outer walls of both the main stirring rod and the secondary stirring rod are provided with helical blades. Each of the first supports and the second support is provided with a motor base, and a drive motor for driving the main stirring rod and the secondary stirring rod to rotate is provided inside the motor base. A discharge pipe is provided on the top of the fixed base, and the bottom end of the discharge pipe extends above the secondary stirring rod.
[0007] Preferably, two grooves are symmetrically formed on both sides of the connecting rod, and a material pipe and a water pipe are respectively arranged in the two grooves. A drain pipe is also provided on the top of the fixed base. The bottom end of the drain pipe extends to the top of the auxiliary stirring rod, and the top end of the drain pipe is connected to the water pipe. The bottom end of the material pipe is connected to the top end of the discharge pipe.
[0008] Preferably, the outer wall of the connecting rod is provided with threaded holes on both sides of the groove, the outer wall of the material pipe and the water pipe is provided with pressure plates, the outer wall of the pressure plates is provided with through holes corresponding to the threaded holes, and a fixing bolt is provided between the pressure plates and the connecting rod.
[0009] Preferably, two perforated plates are symmetrically arranged at the top of the connecting rod, and the tops of the material pipe and the water pipe both penetrate the perforated plates.

[0011] Preferably, both the main stirring rod and the auxiliary stirring rod have protruding spikes on their outer walls.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] The mixing rod assembly includes a main mixing rod and two auxiliary mixing rods. The two auxiliary mixing rods crush and mix the oil-based sludge, while simultaneously conveying it to both sides of the main mixing rod. The main mixing rod then remixes the oil-based sludge from both sides, which helps to improve the crushing degree of the oil-based sludge, thereby facilitating the mixing of the oil-based sludge with concrete, shortening the mixing time, and effectively improving the mixing efficiency.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model provides, for example Figure 1 - Figure 5 The drilling oil-based sludge treatment device shown includes a fixed base 7, a connecting rod 1 fixed to the top of the fixed base 7, and a stirring rod assembly provided on the outer wall of the fixed base 7. The stirring rod assembly includes two first supports 8 and a second support 10 provided on the outer wall of the fixed base 7. Each of the two first supports 8 is provided with a main stirring rod 9, and the second support 10 is provided with a secondary stirring rod 101. The outer walls of the main stirring rod 9 and the secondary stirring rod 101 are provided with spiral blades. Each of the first supports 8 and the second support 10 is provided with a motor base 12. The motor base 12 is provided with a drive motor for driving the main stirring rod 9 and the secondary stirring rod 101 to rotate. The top of the fixed base 7 is provided with a discharge pipe 6, and the bottom end of the discharge pipe 6 extends to the top of the secondary stirring rod 101.
[0024] In the process of treating oil-based sludge, the top of the connecting rod 1 is fixedly connected to the end of the mechanical arm of an external excavator with bolts. The user operates the excavator to move the connecting rod 1, which in turn drives the main mixing rod 9 and the auxiliary mixing rod 101. The drive motor drives the main mixing rod 9 and the auxiliary mixing rod 101 to rotate. During the rotation of the main mixing rod 9, the spiral blades on the outer wall of the main mixing rod 9 stir and push the oil-based sludge towards the auxiliary mixing rod 101. At the same time, the auxiliary mixing rod 101 re-stirs and mixes the oil-based sludge pushed by the main mixing rod 9. Meanwhile, concrete is sprayed out from the discharge pipe 6. During the process of stirring the oil-based sludge, concrete is also mixed into the oil-based sludge, achieving the purpose of mixing oil-based sludge and concrete.
[0025] like Figure 1 - Figure 3As shown, two grooves 14 are symmetrically opened on both sides of the connecting rod 1. The material pipe 3 and water pipe 4 are respectively arranged in the two grooves 14. The top of the fixing base 7 is also provided with a drain pipe 41. The bottom end of the drain pipe 41 extends to the top of the auxiliary stirring rod 101. The top end of the drain pipe 41 is connected to the water pipe 4. The bottom end of the material pipe 3 is connected to the top end of the discharge pipe 6. The outer wall of the connecting rod 1 is provided with threaded holes on both sides of the groove 14. The outer walls of the material pipe 3 and water pipe 4 are provided with pressure plates 5. The outer wall of the pressure plate 5 is provided with through holes corresponding to the threaded holes. The pressure plate 5 and the connecting rod 1 are provided with fixing bolts 16. The material pipe 3 and water pipe 4 are placed in the groove 14. Then, multiple pressure plates 5 are used to press the material pipe 3 and water pipe 4 into the groove 14. Finally, the fixing bolts 16 pass through the pressure plate 5 and are connected to the threaded holes on the outer wall of the connecting rod 1.
[0026] like Figure 1 - Figure 3 As shown, two perforated plates 2 are symmetrically arranged at the top of the connecting rod 1. The top ends of the material pipe 3 and the water pipe 4 both pass through the perforated plates 2. It should be noted that the perforated plates 2 are used to change the direction of the ends of the material pipe 3 and the water pipe 4. By changing the direction of the ends of the material pipe 3 and the water pipe 4, it is possible to connect the external concrete conveying pipe to the material pipe 3 and the external clean water conveying pipe to the water pipe 4.
[0027] like Figure 3 and Figure 4 As shown, a heat-conducting plate 13 is provided on one end face of the motor base 12, and a sealing plate 131 is provided on the other side. A sealing ring 15 is provided on the sealing plate 131. The side walls of the heat-conducting plate 13 and the sealing plate 131 are in contact with the end face of the motor base 12. A circular hole is opened in the middle of the motor base 12, and the drive motor (not shown in the figure) is fixed in the circular hole. The heat-conducting plate 13 is in direct contact with the drive motor. The heat emitted by the drive motor is conducted to the heat-conducting plate 13, and the heat-conducting plate 13 dissipates the heat to the air to facilitate the heat dissipation of the drive motor. The output shaft of the drive motor passes through the hole in the middle of the sealing ring 15 and is then connected to the ends of the main stirring rod 9 and the auxiliary stirring rod 101.
[0028] like Figure 1 and Figure 2 As shown, both the main stirring rod 9 and the auxiliary stirring rod 101 are provided with protruding barbs 11 on their outer walls. During the rotation of the main stirring rod 9 and the auxiliary stirring rod 101, the protruding barbs 11 on their outer walls rotate synchronously with the main stirring rod 9 and the auxiliary stirring rod 101. The protruding barbs 11 can break up the mud lumps in the oil-based sludge, making it easier to quickly break up the mud lumps in the oil-based sludge, thereby improving the mixing degree of oil-based sludge and concrete, and effectively improving the solidification effect of oil-based sludge.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
