Description

Technical Field

[0001] The invention belongs to the technical field of separators, and in particular relates to a spring pressure regulating disc centrifugal separation device. Background Art

[0002] At present, during the compression ignition process of a fuel engine, a small amount of the high-pressure combustible mixed gas and combustion gas in the cylinder will enter the crankcase through the gap between the cylinder and the piston, forming a mixed gas mist containing oil mist, air, water vapor and exhaust gas. These mixed gas mists gather in the crankcase, causing the pressure in the crankcase to be too high, affecting the engine working condition and damaging the crankcase seal. In order to avoid and reduce the impact of the mixed gas in the crankcase on the engine working condition, it is necessary to separate the mixed gas mist from the crankcase into gas and liquid.

[0003] Most of the current centrifugal separators have low separation efficiency, and the separated oil is not easy to discharge quickly. Moreover, after long-term use, when the pressure in the drive chamber is too high, the separated oil may not be able to be discharged normally due to pressure problems. Summary of the invention

[0004] The purpose of the present invention is to provide a spring pressure regulating disc centrifugal separator with simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A spring pressure-regulated disc centrifugal separation device comprises a separator body, the separator body comprises a separator shell, a rotatable rotor is arranged inside the separator shell, the separator shell comprises an inlet, an outlet and a drive chamber, an oil-gas mixture flows in from the inlet, is centrifugally separated by the rotor, the gas portion is discharged from the outlet, and the liquid portion enters the drive chamber, the rotor comprises a rotating shaft, the rotating shaft is a hollow structure, connecting the inlet and the drive chamber, a regulating valve structure is connected inside the rotor, and the regulating valve structure regulates the pressure of the inlet and the drive chamber.

[0007] As a further optimization solution of the present invention, the regulating valve structure includes a spring, a valve body and a hollow plug, the spring is arranged between the plug and the valve body, and the valve body is acted upon by the elastic force of the spring to isolate the inlet from the drive chamber.

[0008] As a further optimization scheme of the present invention, the rotor includes a separation disc and a separation disc base, the separation disc is fixedly connected to the rotating shaft, the regulating valve structure is arranged at the top of the rotating shaft, the lower end of the separator shell is fixedly connected to the lower shell, the lower end of the rotating shaft is inserted into the interior of the lower shell, and the outer surface of the rotating shaft is fixedly connected to an impeller near the lower end.

[0009] As a further optimization scheme of the present invention, a pressure regulating valve is arranged at the upper end of the separator shell, an air intake structure is arranged inside the separator shell, the air intake structure includes an air intake upper cover and an air intake lower seat, and an air outlet channel is opened inside the separator shell.

[0010] The beneficial effects of the present invention are as follows: the present invention is provided with a spring, which is connected to the valve body. When the pressure in the driving chamber is too large, the valve body is lifted up to compress the spring, which is connected to the driving chamber through the inlet, thereby reducing the pressure in the driving chamber, and then adjusting the pressure difference between the product cavity and the driving chamber, so that the product can return oil normally; the device has a simple structure, is easy to operate, and is flexible to use. It is convenient for normal oil discharge in the centrifugal separator and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS
