An automatic variable diameter cyclone separation device for overflow pipe

Abstract

The utility model relates to an automatic variable-diameter cyclone separation device for an overflow pipe. The main purpose is to solve the problem that the optimal separation ratio of the existing cyclone separator cannot be adjusted in real time due to the fixed structure. It is characterized in that: the cyclone separation device also includes a diameter-adjusting motor, a controller and a pressure sensing device; wherein, the pressure sensing device 4 is screwed into the inside of the inlet pipe of the device to realize the pressure at the inlet. monitoring, and synchronously transmit the measured pressure to the controller; the controller converts the pressure signal into the number of rotations of the diameter-adjusting motor, and then uses the variable-diameter sheet group to adjust the diameter of the variable-diameter overflow pipe; the variable-diameter The radial piece group is composed of 6 curved pieces that surround and stagger together. The positioning is completed by the upper and lower positioning pins and the overflow pipe shell. Under the adjustment of the variable diameter regulating valve, each curved piece is rotated and offset according to a certain track. Complete immediate diameter reduction of the entire overflow pipe.

Description

Technical field: [0001] The invention relates to a separation device applied in the fields of petroleum, chemical industry, environmental protection and the like, in particular to a multi-phase flow separation device applied to the working condition of unstable liquid inflow. Background technique: [0002] Nowadays, hydrocyclones have been widely used in petroleum, chemical industry, metallurgy, environmental protection, electric power, water treatment, etc. field. During the use of the hydrocyclone, its working performance is usually evaluated by separation efficiency and particle size efficiency, and the applicability of the hydrocyclone is tested once. In practical application, the separation performance of the hydrocyclone is affected by many factors. The overflow split rate of the hydrocyclone is an important operating parameter in the process of cyclone separation, and it is also an important performance parameter. Efficiency has a significant impact. There are two ...

Problems solved by technology

However, the operation process of the above two methods is relatively complicated, and it is difficult to adjust the diameter of the overflow pipe in time and continuously to achieve the best overflow split rate

In the actual application process, the hydrocyclone is often unable to maintain the optimal split flow rate, which leads to its low separation efficiency in many separation conditions with unstable liquid intake, which limits the application of the hydrocyclone.
