Description

Technical Field

[0002] The sum of oil and gas reservoirs in the same oil and gas producing area under the control of a single geological structure (or formation) factor. An oil and gas field may have one or more oil and gas reservoirs. The area with mainly oil reservoirs is called an oil field. Desander is a device that separates impurities from gas, water or wastewater. It is mainly suitable for water quality treatment and control of raw water and replenishment water, such as: oil field drilling, trenchless horizontal directional crossing, mud purification cyclone separation in coalbed methane drilling, river water and well water desanding, coal washing water, industrial mineral processing, solid-liquid separation, liquid degassing and separation of immiscible liquids, etc. In oil field desanding operations, desanders are often used to separate sand from liquid by centrifugal force. However, in existing devices, it is impossible to clean the conveyor belt in real time, which can easily lead to sand accumulation on the conveyor belt, which is inconvenient. To solve the above problems, we propose the following device. Utility Model Content

[0030] By adopting the above technical solution, the oilfield desander is provided with an electric telescopic rod 16 and a pressure roller 22. When people need to extrude the sand material on the upper surface of the conveyor belt 37, they first convey the sand material on the conveyor belt 37 to the bottom of the pressure roller 22, and then control the electric telescopic rod 16 to start moving downward through the control switch 39, so that the pressure roller 22 squeezes the sand material on the upper surface of the conveyor belt 37, thereby squeezing out the liquid in the sand material, thereby facilitating people to separate the liquid in the sand material on the conveyor belt 37, making the device practical.

[0031] Specifically, a support leg 33 is fixedly connected to the upper surface of the workbench 1, and a barrel 14 is fixedly connected to the front end of the support leg 33. A third shell 25 is fixedly connected to the upper surface of the barrel 14. A second motor frame 26 is fixedly connected to the upper surface of the third shell 25. A third motor 27 is fixedly connected to the front end of the second motor frame 26. A shaft rod 29 is fixedly connected to the lower end of the output shaft of the third motor 27. A fourth bearing 28 is penetrated through the upper surface of the barrel 14. The shaft rod 29 is penetrated inside the fourth bearing 28. A centrifugal blade 30 is fixedly connected to the surface of the shaft rod 29. A spiral rod 31 is fixedly connected to the lower end of the shaft rod 29.

Under the action of centrifugal force, after the heavier particles in the material hit the inner wall of the cylinder 14, because their gravity is greater than the centrifugal force, they will gradually slide downward under the action of gravity, while the lighter part of the material cannot sink under the action of the swirl, and will be discharged through the discharge port 35, and the sand particles sliding downward are discharged from the sand guide head 34 to the conveyor belt 37.

The liquid in the sand material on the conveyor belt 37 is separated. When people need to clean the conveyor belt 37, they only need to control the driving motor 1301 to operate through the switch 39, thereby driving the positive and negative threaded columns 1302 to rotate. With the cooperation of the positive and negative threaded columns 1302 and the second threaded cap 1305, the two mounting plates 1306 are driven to move away from or towards each other. The two mounting plates 1306 respectively drive the two mounting rods 1307 to move, thereby achieving the purpose of replacing the cleaning brush 1308. Then, the first motor 2 is controlled to start operating through the switch 39, thereby driving the threaded column 4 to start rotating. With the cooperation of the first threaded cap 7 and the threaded column 4, the cleaning component 13 is driven to move toward the conveyor belt 37, thereby facilitating people to clean the conveyor belt 37 and improving the practicability of the device.
