Description

Technical Field

[0001] This utility model relates to the field of petroleum additives conveying technology, and in particular to a conveying mechanism for mixing petroleum additives. Background Technology

[0002] In the processes of oil extraction, drilling, gathering and transportation, and subsequent processing, a wide variety of petroleum additives are required, such as viscosity reducers, demulsifiers, corrosion inhibitors, wax removers, and oil displacement agents. Before use, these additives usually need to be dissolved, diluted, or mixed with other components in a specific mixing tank to form a homogeneous mixture.

[0003] Currently, the industry generally uses centrifugal pumps or screw pumps as the core conveying equipment to pump the mixed liquid directly from the mixing tank to the point of use such as wellhead, pipeline or treatment device.

[0004] However, in the aforementioned prior art, petroleum additives, due to their high density, tend to accumulate at the bottom of the mixing tank, leading to sedimentation and blockage, which affects the continuity of petroleum additive addition. Therefore, there is an urgent need to provide a mixing conveying mechanism that prevents petroleum additive blockage and provides efficient, reliable, and continuous conveying. Utility Model Content

[0005] The purpose of this utility model is to provide a conveying mechanism for mixing petroleum additives, which aims to solve the problem in the prior art that petroleum additives with high density tend to accumulate at the bottom of the mixing tank, resulting in sedimentation and blockage, which affects the continuity of petroleum additive addition.

[0006] To achieve the above objectives, this utility model provides a conveying mechanism for mixing petroleum additives, including a mixing tank and auxiliary components. The auxiliary components include a hollow shaft, a stirring rod, a suction pipe, a pressure pump, a shaped nozzle, a corrosion-resistant magnetic pump, a T-connector, and a drive component. The auxiliary components are connected to the mixing tank. The mixing tank has a circular hole that rotatably engages with the hollow shaft. The corrosion-resistant magnetic pump is connected to the mixing tank and located below it. The T-connector is connected to the corrosion-resistant magnetic pump. The pressure pump is connected to the three-way pipe and located above the three-way pipe. The material extraction pipe is connected to the pressure pump and located at the output end of the pressure pump. The material extraction pipe is rotatably engaged with the hollow shaft. The irregularly shaped nozzle is connected to the material extraction pipe and located at the end of the material extraction pipe away from the pressure pump. The stirring rod is fixedly connected to the hollow shaft and located on the outer side wall of the hollow shaft. The driving component is connected to the hollow shaft and the mixing tank respectively.

[0007] The auxiliary component further includes a limiting ring and a right-angle ring. The limiting ring is fixedly connected to the hollow shaft and is located on the outer side wall of the hollow shaft. The right-angle ring is fixedly connected to the mixing tank and is located on the inner top wall of the mixing tank. The right-angle ring and the limiting ring are rotatably engaged.

[0008] The auxiliary components also include a controller and a liquid level sensor. The liquid level sensor is fixedly connected to the mixing tank and located on the inner wall of the mixing tank. The controller is fixedly connected to the mixing tank and located on the outer wall of the mixing tank.

[0009] The driving component includes a mounting frame, a drive motor, a first gear, and a second gear. The mounting frame is fixedly connected to the mixing tank and located above the mixing tank. The drive motor is fixedly connected to the mounting frame and located on the inner top wall of the mounting frame. The first gear is fixedly connected to the hollow shaft and located on the outer side wall of the hollow shaft. The second gear is fixedly connected to the drive motor and located at the output end of the drive motor, and the second gear meshes with the first gear.

[0010] The driving component further includes a rolling bearing housing and a connecting rod. The rolling bearing housing is disposed above the mixing tank, and the connecting rod is fixedly connected to the second gear and located below the second gear. The connecting rod is interference-fitted with the rolling bearing housing.

[0011] This utility model discloses a conveying mechanism for mixing petroleum additives. In use, the driving component drives the hollow shaft to rotate, which in turn drives the stirring rod to mix the petroleum additives in the mixing tank, preventing sedimentation. Simultaneously, a corrosion-resistant magnetic pump draws additives from the bottom of the mixing tank and transports them to subsequent process equipment through a pipe connected to the right end of the three-way pipe. Meanwhile, a pressure pump draws petroleum additives from the top of the three-way pipe, pressurizes them, and sprays them out through the extraction pipe from the irregularly shaped nozzle, forming a circulating flow that further breaks down the sediment layer, ensuring the continuous addition of petroleum additives. This method solves the problem that petroleum additives with high density tend to accumulate at the bottom of the mixing tank, causing sedimentation and blockage, thus affecting the continuity of petroleum additive addition.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the conveying mechanism for mixing petroleum additives according to this utility model. Figure 2 This is a right view of the conveying mechanism for mixing petroleum additives according to this utility model. Figure 3 This is the utility model Figure 2 A sectional view along line AA.

[0019] This utility model provides a conveying mechanism for mixing petroleum additives, including a mixing tank 101 and auxiliary components. The auxiliary components include a hollow shaft 102, a stirring rod 103, a material extraction pipe 104, a pressure pump 105, a shaped nozzle 106, a corrosion-resistant magnetic pump 107, a three-way pipe 108, a limiting ring 109, a right-angle ring 110, a controller 111, a liquid level sensor 112, and a driving component. The driving component includes a mounting bracket 113, a drive motor 114, a first gear 115, a second gear 116, a rolling bearing seat 117, and a connecting rod 118. The mixing tank 101 has a circular hole 119.

[0020] The auxiliary component is connected to the mixing tank 101; the mixing tank 101 has a circular hole 119, which is rotatably engaged with the hollow shaft 102; the corrosion-resistant magnetic pump 107 is connected to the mixing tank 101 and located below it; the three-way pipe 108 is connected to the corrosion-resistant magnetic pump 107 and located at its output end; the pressure pump 105 is connected to the three-way pipe 108 and located above it. The material extraction pipe 104 is connected to the pressure pump 105 and is located at the output end of the pressure pump 105. The material extraction pipe 104 is rotatably engaged with the hollow shaft 102. The irregularly shaped nozzle 106 is connected to the material extraction pipe 104 and is located at the end of the material extraction pipe 104 away from the pressure pump 105. The stirring rod 103 is fixedly connected to the hollow shaft 102 and is located on the outer side wall of the hollow shaft 102. The driving component is connected to the hollow shaft 102 and the mixing tank 101 respectively.

[0021] In this embodiment, during use, the driving component drives the hollow shaft 102 to rotate, which in turn drives the stirring rod 103 to mix the petroleum additives in the mixing tank 101 to prevent sedimentation. Simultaneously, the corrosion-resistant magnetic pump 107 draws the additives from the bottom of the mixing tank 101 and transports them to subsequent process equipment through the pipe connected to the right end of the three-way pipe 108. Meanwhile, the pressure pump 105 draws the petroleum additives from the top of the three-way pipe 108, pressurizes them, and sprays them out from the irregular nozzle 106 through the extraction pipe 104, forming a circulating flow. This further breaks down the sediment layer and ensures the continuity of petroleum additive addition. In this way, the problem of petroleum additives with high density accumulating at the bottom of the mixing tank 101, causing sedimentation and blockage, and affecting the continuity of petroleum additive addition is solved.

[0022] Furthermore, the limiting ring 109 is fixedly connected to the hollow shaft 102 and is located on the outer side wall of the hollow shaft 102, and the right-angle ring 110 is fixedly connected to the mixing tank 101 and is located on the inner top wall of the mixing tank 101, and the right-angle ring 110 and the limiting ring 109 are rotatably engaged.

[0023] In this embodiment, the limiting ring 109, together with the right-angle ring 110, restricts the axial movement of the hollow shaft 102, preventing the hollow shaft 102 from falling out of the circular hole 119 and ensuring the normal rotation of the hollow shaft 102.

[0024] Furthermore, the liquid level sensor 112 is fixedly connected to the mixing tank 101 and located on the inner side wall of the mixing tank 101, and the controller 111 is fixedly connected to the mixing tank 101 and located on the outer side wall of the mixing tank 101.

[0025] In this embodiment, the liquid level sensor 112 and the controller 111 are linked to automatically stop the corrosion-resistant magnetic pump 107 and the pressure pump 105 when the liquid level is low, preventing the pump from running dry and being damaged, and improving the safety and automation level of the system.

[0026] Furthermore, the mounting bracket 113 is fixedly connected to the mixing tank 101 and located above the mixing tank 101; the drive motor 114 is fixedly connected to the mounting bracket 113 and located on the inner top wall of the mounting bracket 113; the first gear 115 is fixedly connected to the hollow shaft 102 and located on the outer side wall of the hollow shaft 102; the second gear 116 is fixedly connected to the drive motor 114 and located at the output end of the drive motor 114, and the second gear 116 meshes with the first gear 115.

[0027] In this embodiment, when in use, the controller 111 starts the drive motor 114, which drives the second gear 116 to rotate. Since the second gear 116 meshes with the first gear 115, the first gear 115 drives the hollow shaft 102 to rotate, driving the stirrer to mix the petroleum additives. The mounting bracket 113 is used to mount the drive motor 114.

[0028] Furthermore, the rolling bearing seat 117 is disposed above the mixing tank 101, the connecting rod 118 is fixedly connected to the second gear 116 and located below the second gear 116, and the connecting rod 118 is interference-fitted with the rolling bearing seat 117.

[0029] In this embodiment, the rolling bearing seat 117 and the connecting rod 118 are used to improve the rotational stability of the second gear 116 and avoid jumping.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
