[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] First, please refer to Figure 1 A vacuum conveyor 100 includes a discharge tank 101, a waterproof valve 102 and a purge device 103.

[0028] In this embodiment, the outer wall of the discharge tank 101 further has a vacuum pump 104 , and the vacuum pump 104 is connected to a pneumatic ball valve 105 .

[0029] In this embodiment, the discharge tank 101 also has a feed port 101b.

[0032] In this embodiment, the purging device 103 further includes: an air blowing device located on the outer wall of the discharge tank 101 , and the air blowing device blows air from the through hole along the guide groove toward the valve plate of the waterproof valve 102 .

[0033] In this embodiment, the purging device 103 uses compressed gas for purging.

[0034] In this embodiment, the purge device 103 eliminates the risk of agglomeration of the raw materials on the waterproof valve 102 due to the reaction with water, ensures the waterproofness of the waterproof valve 102, improves the accuracy of the waterproof valve 102, and has a wider range of uses.

[0035] In this embodiment, it also includes: a discharge valve 106 located in the discharge tank 101, and when the discharge valve 106 is opened, the raw materials in the discharge tank 101 pass through the discharge valve 106 and the waterproof valve 102, and are discharged from the discharge port 101a.

[0036] In this embodiment, it also includes: a filter cartridge 107 located in the discharge tank 101 , the filter cartridge 107 is far away from the discharge port 101 a , and the waterproof valve 102 prevents water vapor from contacting the raw materials on the filter cartridge 107 .

[0037] In this embodiment, it also includes: a back-blowing pulser 108 located at the filter cartridge 107 for intermittently blowing the filter cartridge 107 to extend the replacement and maintenance cycle of the filter cartridge 107 .

[0038] In this embodiment, in order to see the schematic diagram of the filter cartridge 107, Figure 1 Make the discharge tank transparent.

[0039] In this embodiment, the back-blow pulser 108 includes a reverse airbag 108a connected to the outer wall of the discharge tank 101, one end of the reverse airbag 108a is connected to a pressure regulating valve 108b, the air outlet end 108d of the reverse airbag 108a is connected to the interior of the discharge tank 101, and the air outlet end 108d of the reverse airbag 108a is also provided with a reverse pulse valve 108c.

[0040] In this embodiment, during the operation of the vacuum conveyor 100, the raw materials enter the discharge tank 101 from the feed port 101b, and under the action of vacuum, are filtered by the filter cartridge 107, and are discharged from the discharge port 101a after passing through the discharge valve 106 and the waterproof valve 102.

[0041] Accordingly, using the above vacuum conveyor 100, please refer to Figure 2 The utility model also provides a vacuum feeding system 200, including the above-mentioned vacuum conveyor 100; a movable feeding station 201 connected to the vacuum conveyor 100; and a stirring tank 202 connected to the vacuum conveyor 100. After the raw materials are fed from the movable feeding station 201, they are transported by the vacuum conveyor 100 and enter the stirring tank 202 from the discharge port 101a.

[0042] In this embodiment, on the one hand, the movable feeding station 201 is combined to control the dust range and reduce the carrying work of the operators; on the other hand, the waterproof valve 102 on the vacuum conveyor 100 is combined to prevent water vapor from invading the discharge tank 101, and at the same time, the purge device 103 on the outer wall of the discharge tank 101 is combined.

At this time, there is no water in the stirring tank 202. After the raw materials enter the stirring tank 202, water is added for stirring. At this time, during the stirring process, water vapor will "run" along the discharge port 101a into the discharge tank 101 and remain in the discharge tank 101. Subsequently, when the raw materials are transported to the discharge tank 101, the raw materials will react with the residual water vapor to form agglomerates, causing the filter cartridge 107 to be blocked. However, the addition of the waterproof valve 102 can prevent water vapor from invading the discharge tank 101, reduce the generation of agglomerates, reduce the number of maintenance times, and improve production efficiency.
