Description

Technical Field

[0001] This utility model relates to the field of oilfield profile control technology, specifically to a device for manufacturing profile control balls for oilfields. Background Technology

[0002] In oilfield development, profile control technology is a crucial means to enhance oil recovery. Profile control pellets, as a novel profile control agent, directly impact profile control effectiveness due to their quality and performance. Traditional profile control pellet manufacturing processes have several shortcomings, such as the inability to adjust raw material ratios online, slow manufacturing speed and difficulty in precise progress control, the inability to digitally display temperature changes during pellet formation in real time, incomplete filling within the mold, and inaccurate detection of key data such as particle size and strength. These shortcomings result in unstable temperature resistance, low sphericity, and low strength in the profile control pellets, affecting their effectiveness in oilfields. Therefore, it is necessary to improve the manufacturing process and equipment for profile control pellets. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a device for manufacturing profile control balls for oil fields.

[0004] This utility model is achieved through the following technical solution: a device for making profile control balls for oil fields is provided, comprising a raw material pretreatment module, a mixing and stirring module, a heating and blending module, a granulation and forming module, and a cooling and shaping module arranged in sequence. The cooling and shaping module includes a water pump, a water collection tank, and a connecting box connected to the outlet of the granulation and forming module. The inlet and outlet of the water pump are respectively connected to the water collection tank and the connecting box. A cooling and shaping water pipe is connected to the upper end of the connecting box. A mesh belt conveyor is installed between the outlet of the cooling and shaping water pipe and the upper opening of the water collection tank.

[0005] The raw material pretreatment module in this solution is used to pre-treat various raw materials such as drying and screening to ensure that the quality and performance of the raw materials meet the requirements. The mixing and stirring module can accurately weigh various raw materials according to the preset formula ratio and fully mix them through a multi-shaft agitator to make the raw materials uniformly compounded. The heating and blending module is used to stir, heat, and blend various raw materials to improve flow performance and facilitate injection into the granulation and molding module. The granulation and molding module granulates the fluid into granules. The cooling and shaping module shapes and cools the granules output from the granulation and molding module through the flow of water to make their surfaces smooth and rounded.

[0006] During operation, the granules output from the granulation and molding module enter the connecting box. After the water pump injects water into the connecting box, it drives the granules to move quickly in the cooling and shaping water pipe, thereby shaping and cooling the granules. Finally, the mixture of water and granules passes through the conveyor belt of the mesh belt conveyor. After the water passes through the conveyor belt, it flows into the water collection tank below, while the granules remain on the conveyor belt and are output outward.

[0007] As an optimization, the raw material pretreatment module includes a dryer and a screening machine, thereby achieving drying and screening.

[0008] As an optimization, the mixing module includes a weighing device and a multi-shaft mixer, thereby achieving automatic weighing and mixing.

[0009] As an optimization, the heated blending module includes an extruder. This heats the material into a fluid state and then extrudes it to a subsequent granulation module.

[0010] As an optimization, the granulation module includes a granulator. The granulator processes the material into granules.

[0011] As an optimization, a temperature control module is also included, comprising temperature sensors respectively disposed within the heating and blending module, the granulation and forming module, and the cooling and shaping module. The temperature control module is used to detect the temperature within these three modules.

[0012] As an optimization, the cooling and shaping water pipe is provided with a horizontal serpentine section. This allows the water to flow back and forth, impacting and facilitating the smooth shaping of particles.

[0013] As an optimization, the upper end of the connecting box is connected to the cooling water pipe via a transparent observation tube. This facilitates observation of the water and particulate matter inside.

[0014] The beneficial effects of this utility model are as follows: The oilfield profile control ball manufacturing device of this utility model effectively improves the processing speed, quality, and performance of profile control balls, giving them good temperature and salt resistance, and meeting the actual needs of oilfield profile control. The device of this utility model has a reasonable structure, is easy to operate, has a high degree of automation, and has broad application prospects. Attached Figure Description
