Fully closed powder recovery post-processing system

Abstract

The invention discloses a whole closed type powder recycling post-processing system which is a 3DRP quick forming and post-processing device with whole closed type automatic powder removal and recycling functions. The whole closed type powder recycling post-processing system is used for automatically removing excessive powder after object forming, and is used for recycling powder with impurities being filtered and screened, wherein the cleanliness of a space can be kept by preventing powder from flying into air during removal of the excessive powder. The whole closed type powder recycling post-processing system comprises a sealing main body, a rotary plate device, an air spraying column device, a negative-pressure device, an air pressure generating device and an impurity filtering device, wherein an object is placed in a sealing chamber of the sealing main body, and is supported by the rotary platedevice; the air spraying column device is used for carrying automatic 360-degree gas-blowing on the object to remove the remainder powder, and the removed remainder powder drops into a powder collecting box for being collected and intensively recycled; and meanwhile, negative-pressure gas-flow filtration is carried out in the sealing chamber, and the powder is filtered by the inner gas flow of the powder collecting box through the impurity filtering device, so that the gas flow is fed back into the sealing chamber so to be subjected to whole closed type remainder powder recycling treatment.

Description

【Technical Field】 [0001] This case is about a powder recovery post-processing system, especially a fully closed powder recovery post-processing system. 【Background technique】 [0002] This system is used for the post-processing of finished products after 3DRP rapid prototyping. The current known technology is manual removal (such as figure 1 (Shown), the operator is required to put his hands into the three-dimensional rapid prototyping post-processing device 1 to manually remove the powder. This method will cause a gap due to the presence of both hands in the operating area 10. The powder is easily removed from the gap when blowing and removing powder Drift out in the air, making the air polluted by powder. [Content of the invention] [0003] The purpose of this case is to provide a fully closed powder recovery post-processing system to solve the problem that the working environment is not polluted by the air of the powder. The objects are placed on the automatic rotating disk in ...

Problems solved by technology

[0003] The purpose of this case is to provide a fully closed powder recovery post-processing system to solve the problem that the working environment will not be polluted by the air of the powder. The column device removes the powder, and there is a guide fan blade in front of the air spray column to swing to increase the area of ​​blown and removed objects, and a filter screen is installed in the sealed chamber, and a negative pressure device is connected to promote the cleaning of the powder in the sealed chamber. The powder in a negative pressure space is not easy to scatter, so as to achieve a better cleanliness of the space, and the cleaned powder in the sealed chamber can also be directly dropped into a powder collection box for recycling, and the powder collection box can also be used in conjunction with the filter impurity device. Filtration of finer floating suspended particles circulates into the sealed chamber, so that the negative pressure device and filter impurity device are used in the sealed chamber to carry out the operation of circulating air guide to filter the remaining powder of dust, and the powder filtered by this system can be used again; In addition, it can not only complete the post-processing of automatic powder removal and recovery, but also carry out manual operation and spray gun to strengthen the 3D molded product to remove powder and clean the powder recovery process
