AI Technical Summary
In existing cylinder head cleaning devices, waste debris easily mixes with the cleaning fluid and re-adheres onto the cylinder head, resulting in poor cleaning effect and low efficiency.
The flow-guiding filtration mechanism includes a filter ring and a flow guide located on the outer periphery of the cleaning clamping device. The debris is thrown into the cleaning fluid by centrifugal force and water flow disturbance. The radial arrangement and secondary disturbance of the flow guide intercept and guide the waste debris, causing it to adhere to the flow guide plate or the inner wall of the cleaning cylinder, rather than adhering to the cylinder head again.
This greatly reduces the problem of waste residue being mixed with the cleaning fluid and agitated onto the cylinder head, thus improving the cleanliness and efficiency of the cleaning process.

The centrifugal force and the disturbance of the water flow can shake the debris such as sand, chips and flash on the cylinder head into the cleaning liquid. The highlight of the present embodiment is that it further comprises a flow guiding and filtering mechanism. The filter ring 31 located at the outer periphery of the cleaning clamping device 2 rotates under the rotation of the cleaning clamping device 2. The flow guiding member 32 provided on the filter ring 31 can produce secondary disturbance and flow guiding to the water flow. The secondary disturbance can increase the turbulence degree of the water flow, and can better flush the waste debris. In addition, due to the radial distribution of the flow guiding plate, the debris such as sand, chips and flash will be intercepted and guided by the water flow disturbance under the radial distribution of the flow guiding plate. With the centrifugal effect, the cylinder head away from the rotation center, so that the waste debris will not fall around the cylinder head under its own gravity, but a part of it will be intercepted and attached to the flow guiding plate, and a part of it will be guided by the flow guiding plate to fall near the inner wall of the cleaning barrel 1 away from the rotation center. In this way, the problem of re-attachment of waste debris mixed with cleaning liquid and stirred onto the cylinder head is greatly reduced, the cleanliness during cleaning is increased, the cleaning effect is improved, and the cleaning efficiency is greatly improved.
