Device for removing product residual oil

Abstract

The invention discloses a device for removing product residual oil. The device comprises a pressure container, a spring, a piston, an air inlet valve, an air outlet valve, a pressure gauge, a form plate, a residual oil collecting tank and a connecting air tube. The piston is arranged in the pressure container, the piston divides the pressure container into an upper cavity and a lower cavity, one end of the spring is connected to the piston, the other end is connected to the bottom of the lower cavity of the pressure container, the air inlet valve, the air outlet valve and the pressure gauge are respectively fixed on the upper cavity of the pressure container, the connecting air tube is connected to the bottom of the lower cavity of the pressure container and the residual oil collecting tank, and the form plate is connected to a workpiece and is fixed at the top of the residual oil collecting tank. By the aid of the device, the entire operation process is sanitary and environmentally friendly, secondary pollution occurs rarely, the residual oil can be gathered and collected into the collecting tank and can be recovered and removed conveniently, oil removal effect is fine, operation is facilitated, equipment is simple, and cost is low.

Description

technical field [0001] The invention relates to a device for cleaning oil stains, in particular to a device for cleaning product residual oil. Background technique [0002] Hydraulic components basically need to be tested before leaving the factory. The test requires hydraulic oil and other media. After the test, there are many difficulties in the treatment of the hydraulic oil remaining in the product. First, it cannot be cleaned with a cleaning machine, because cleaning may cause Moisture enters the product, causing the product to rust. If protective measures are taken before cleaning, the cost will be higher. Secondly, many products have irregular structures, and the cleaning process is not easy to clean up the residual oil. The current common measure is to use the gravity of the residual oil to slowly make the residual oil flow out of the product by placing the product, which is inefficient, takes a long time, and is not easy to clean up. In addition, there is a method...

[0002] Hydraulic components basically need to be tested before leaving the factory. The test requires hydraulic oil and other media. After the test, there are many difficulties in the treatment of the hydraulic oil remaining in the product. First, it cannot be cleaned with a cleaning machine, because cleaning may cause Moisture enters the product, causing the product to rust. If protective measures are taken before cleaning, the cost will be higher

Secondly, many products have irregular structures, and the cleaning process is not easy to clean up the residual oil

At present, the common measure is to use the gravity of the residual oil to slowly let the residual oil flow out of the product by placing the product, which is low in work efficiency, takes a long time, and is not easy to clean up.

In addition, there is a method of rotating or blowing air. The rotating product uses centrifugal force to throw the oil out of the product. On the one hand, the equipment is more complicated and there are safety hazards. On the other hand, the residual oil thrown out will splash and pollute the environment. Sub-contaminated product surface

Blow air to remove residual oil, the equipment is relatively simple, and there are also environmental pollution and secondary pollution on the product surface
