4results about How to "Improve sand cleaning efficiency" patented technology

This invention discloses an automatic tilting coupler sand removal device, relating to the field of coupler processing technology. It includes a cleaning box with a tilting bucket rotatably mounted inside. A power component is installed on the cleaning box to drive the tilting bucket to reciprocate. A frame is fixed to the bottom inner wall of the cleaning box, and a swing tube with a superior arc cross-section is rotatably mounted on the top of the frame. A nozzle is coaxially inserted into the swing tube. A nozzle head is fixed and connected to the spray tube. An air pipe is fixed inside the cleaning box and connected to an external air source. A connecting hose is fixed and connected between the spray tube and the air pipe. A transmission mechanism, driven by the power component, is installed inside the cleaning box to drive the nozzle to swing up and down, to reciprocate within the swing tube, and to slide axially within the swing tube. This invention can clean the coupler from multiple angles, preventing iron sand residue inside the coupler, reducing the impact on subsequent coupler assembly, reducing cleaning time, and improving sand removal efficiency.

This invention belongs to the field of casting post-treatment technology and discloses a sand removal device and method for cylinder head castings, including a frame, an ultrasonic sand removal tank, a contact ultrasonic component, a high-pressure jet component, and a water circulation component. The ultrasonic sand removal tank is installed on the top surface of the frame, and ultrasonic transducers are arranged on the inner wall of the ultrasonic sand removal tank. The contact ultrasonic component includes a clamp support, a contour clamp, and ultrasonic units. The clamp support is fixedly connected to the frame, and the contour clamp is detachably connected to the clamp support and suspended in the ultrasonic sand removal tank. The casting is placed at the bottom of the contour clamp, and multiple ultrasonic units are installed on the top of the contour clamp and are in contact with the surface of the casting. The high-pressure jet component includes a high-pressure jet nozzle arranged on the inner wall of the ultrasonic sand removal tank, which sprays water into the inner cavity opening of the casting. The water circulation component includes a water storage tank, which is connected to the ultrasonic sand removal tank and the high-pressure jet nozzle. This invention does not produce toxic substances that pollute the environment and has the technical effect of improving the sand removal quality of cylinder head castings.
