Abstract

An investment casting member cleaning device includes a residue sand cleaning mechanism; the residue sand cleaning mechanism includes a storage chamber, a sand pump, a macropore filtering screen, a micropore filtering screen, a cleaning chamber, a rotation basket, a rotation basket motor, a first lifting device, a first high pressure water sand sprayer, a high pressure water conveying pipe, a sand conveying pipe, a rotation disc, a rotation disc motor, and a second lifting device, a second high pressure water sand sprayer; the storage chamber includes a bottom wall, a sand chamber, and a waste water chamber; the sand chamber includes sealed side walls extending from the bottom wall upward, and the side walls are fixedly connected to the top of the bottom wall; the waste water chamber extends upward from the bottom wall, and a water outlet hole is formed in the upper part of the waste water chamber; a hole is formed in a side wall between the sand chamber and the waste water chamber; the position of the hole is lower than the position of the water outlet hole; and the sand pump is arranged on the central bottom of the sand chamber. The investment casting member cleaning device is nontoxic, can avoid pollution, dust and strong noise, and will not damage an investment casting member cleaning cabinet of a casting member.

Description

technical field [0001] The invention relates to equipment for cleaning residual casting sand on the surface of investment castings, which is suitable for cleaning residual casting sand on the surface of investment castings. Background technique [0002] The main methods for removing residual casting sand on the surface of existing investment castings are: [0003] The first method: soak the investment casting with residual sand in high concentration hydrofluoric acid, mixed strong acid or strong alkali in molten state, and use chemical reaction to remove or loosen it. [0004] The second method: put the investment casting with residual sand or residual sand that has been loosened by the first method in a shot blasting machine or sandblasting machine, and let small steel shots or abrasives with high speed and high kinetic energy impact the Investment castings, and the residual casting sand on the surface is removed. [0005] But the above two methods have many disadvantages...

AI Technical Summary

Problems solved by technology

[0006] The first method will produce a large amount of toxic industrial waste gas and waste water, which will cause serious pollution to the environment, endanger the health of workers, and have hidden dangers of corrosion to castings.

[0007] The second method is easy to generate high-decibel noise and a large amount of dust, causing harm to workers, polluting the surrounding environment, and reducing the precision of castings
