[0011] Figure 1 Shown is a schematic structural diagram of a vacuum feeding device in a specific embodiment of the utility model. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] Ginseng Figure 1 As shown, the vacuum feeding device in this embodiment includes a feeder 1, a storage barrel 2, a reaction chamber 3 and a connecting pipe 4. The top end of the storage barrel 2 is connected to the discharge end of the feeder 1 through a first plate valve 5, and the bottom end of the storage barrel 2 is connected to the feed end of the reaction chamber 3 through a second plate valve 6. The two ends of the connecting pipe 4 are respectively connected to the storage barrel 2 and the reaction chamber 3. A first control valve 7 is provided on the connecting pipe 4. An exhaust pipe 8 is connected to the connecting pipe 4 between the first control valve 7 and the storage barrel 2, and a second control valve 9 is provided on the exhaust pipe 8.

[0014] Furthermore, the first control valve 7 and the second control valve 9 are both solenoid valves.

[0015] Furthermore, a material level meter 10 is provided in the storage barrel 2 .

[0016] In this technical solution, through structural coordination, the vacuum degree of the storage barrel and the reaction chamber can be kept consistent during the material conveying process, ensuring smooth vacuum automatic feeding.

[0017] Specific implementation principle:

[0018] Open the first plate valve, close the first control valve, the second control valve and the second plate valve, so that the material in the feeder enters the storage barrel. After the material level meter detects the feeding amount, close the first plate valve, open the first control valve, so that the storage barrel and the reaction chamber maintain the same vacuum degree, open the second plate valve, so that the material in the storage barrel enters the reaction chamber, open the second control valve after entering, close the first control valve and the second plate valve, and break the vacuum of the storage barrel. In this way, continuous and smooth feeding can be achieved repeatedly.

[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0020] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
