Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing liquid recovery equipment, and in particular to a grinding cloth slag recovery net device. Background Art

[0002] Since the grinding fluid needs to be recycled, the recovery pipe is generally located at the lower side where the grinding fluid falls, so that it can be effectively recycled to the greatest extent and impurities will not be brought into the recovery pipe to affect the quality of the grinding fluid. Due to the small space of this machine, the original design structure was defective, that is, the recovery pipe was located directly below the grinding cloth instead of the grinding fluid, so the polishing cloth residue and debris produced after polishing would fall into the grinding fluid recovery pipe.

[0003] Due to the design position of the machine components, there is a problem in the grinding process that grinding cloth residue and grinding liquid crystals will frequently block the grinding liquid recovery pipeline. Frequent blockages will make the grinding liquid unable to be recovered or impurities will be brought into the grinding liquid (resulting in faster frequency of grinding liquid replacement and higher costs). The direct consequence is that the machine alarm stops production, which will indirectly affect product quality. Summary of the invention

[0004] The present invention mainly solves the deficiencies in the prior art and provides a grinding cloth residue recovery net device, which has the advantages of simple structure, good effect and high operation stability. It solves the problem of grinding cloth residue blocking the recovery pipeline, improves the quality of the recovery liquid, reduces the frequency of changing the grinding liquid, and reduces the frequent alarm maintenance caused by blockage.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: A grinding cloth residue recovery net device comprises a polishing machine case, wherein a grinding disc is arranged inside the polishing machine case, a polishing cloth nested with the grinding disc is arranged on the outer circle of the grinding disc, a recovery pipe connected with the polishing machine case is arranged at the lower end of the polishing machine case, and a recovery filter assembly is arranged inside or at the upper end of the recovery pipe.

[0006] Preferably, the recovery filtration assembly comprises a filter mesh, and a spacer plug is provided between the filter mesh and the recovery pipe.

[0007] Preferably, the recovery filter assembly comprises a liquid leakage sleeve, and a bottom mesh plate which is integrally nested with the liquid leakage sleeve is provided at the lower end of the liquid leakage sleeve.

[0008] Preferably, a filter plate is provided at the upper end of the leakage sleeve, and a plurality of filter slots distributed in an array are provided on the filter plate.

[0009] Preferably, a movable cover is provided between the filter disc and the bottom mesh plate, the movable cover comprises a cover mounting ring, a fixed fan-shaped plate is provided on the cover mounting ring, a movable fan-shaped plate is provided at the lower end of the fixed fan-shaped plate, and a rotating shaft rod is provided between the movable fan-shaped plate and the fixed fan-shaped plate.

[0010] Preferably, the upper end of the movable sector plate is provided with a lever extending out of the filter plate, and the filter plate is provided with a limit groove that is slidably connected with the lever. When the polishing machine box needs to be cleaned with water, the movable sector plate and the fixed sector plate can be closed by the lever.

[0011] Preferably, a hemispherical ball cover filter with a downward opening is provided between the movable cover and the bottom mesh plate. Since the temperature of the recovered polishing liquid is high, the water vapor during recovery is easy to rebound, and the ball cover filter is used to filter while preventing the rebound pressure of the recovered polishing liquid water vapor from clogging the recovery pipe.

[0012] The present invention can achieve the following effects: The present invention provides a grinding cloth residue recovery net device, which has the advantages of simple structure, good effect and high operation stability compared with the prior art. It solves the problem of grinding cloth residue blocking the recovery pipeline, improves the quality of the recovery liquid, reduces the frequency of changing the grinding liquid, and reduces the frequent alarm maintenance caused by blockage.
