Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Fig. 1 shows a structure of a powder conveying line protection device according to an embodiment of the present invention, and only portions related to the embodiment of the present invention are shown for convenience of description.
As shown in fig. 1, the powder transfer chain protection device that this embodiment provided, including powder transfer chain 1, be equipped with safety cover 2 on the powder transfer chain, be equipped with window 3 and removable cover 4 on the safety cover, still the intercommunication has protection gas device 5 on the powder transfer chain, the powder transfer chain with be equipped with flowmeter 6 and relief pressure valve 7 between the protection gas device in proper order.
To facilitate understanding of the specific working process of this example, the roller kiln is marked 8 and the sagger is marked 9.
The working process is as follows: the protective gas device is started, the pressure and the flow of the introduced compressed air are controlled by adjusting the pressure reducing valve and the flow meter, after the whole protective cover is filled with the compressed air, a powder conveying line control program is started, the saggars are conveyed onto the powder conveying line by the roller kiln and then move on the powder conveying line, the window is made of organic glass, the protective gas device has the characteristics of high temperature resistance and high transparency, the observation and the point inspection of the internal condition of the powder conveying line are facilitated, the movable cover plate is installed to be beneficial to the detection of the saggars and the maintenance work of maintenance personnel, a large amount of dust foreign matters are covered on the window and the movable cover plate after a period of time, the protective gas device for the powder conveying line has a protective effect, the dust foreign matters outside can be effectively intercepted, when the maintenance is needed, the window can be directly taken up or the movable cover plate is slightly pushed upwards to be, the device has the advantages of high automation degree, simple structure and convenient operation.
