DETAILED DESCRIPTION

[0023] In order to make the purpose, 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 only used to explain the present invention and are not intended to limit the present invention.

[0024] In order to improve the mixing efficiency of the stimulator powder, the utility model provides an stimulator powder pneumatic mixing device, which can mix the powders with each other during the jet process, thereby improving the mixing efficiency of the powders.

[0025] It should be noted that the stimulant powder pneumatic mixing device of the present invention is used for but not limited to the mutual mixing of stimulant powders. For the convenience of explanation, in the present invention, only the application of the stimulant powder pneumatic mixing device to the mutual mixing of stimulant powders is used as an example for explanation. The principle of applying the stimulant powder pneumatic mixing device to other types of equipment is essentially the same as the principle applied to the mutual mixing of stimulant powders, and will not be elaborated here.

[0026] See also Figure 1 , Figure 1 The schematic diagram of the structure of an exciter powder pneumatic mixing device according to one embodiment of the present invention includes a mixing assembly 100 and several feeding assemblies 200. The feeding assembly 200 includes a storage tank 210 and a powder pump 220. The storage tank 210 is used to store powder. The feed end of the powder pump 220 is connected to the storage tank 210 and is used to discharge the powder in the storage tank 210. The mixing assembly 100 includes an air pump 110, a jet tube 120, and a first impeller 130. The air pump 110 is connected to one end of the jet tube 120 and is used to introduce a high-speed airflow into the jet tube 120. The first impeller 130 is rotatably embedded in the other end of the jet tube 120. The output ends of the several powder pumps 220 are connected to the middle of the jet tube 120. The high-speed airflow drives the first impeller 130 to rotate, thereby mixing various powders.

[0027] In this embodiment, first, various types of powders are filled into each storage tank 210 one by one, and the feed end of the powder pump 220 is connected to the storage tank 210. The powder in the storage tank 210 is introduced into the jet tube 120 through the powder pump 220. Since the air pump 110 introduces a high-speed airflow into the jet tube 120, the high-speed airflow will drive the powder to move in the jet tube 120. When the powder reaches the position of the first impeller 130, the rotating first impeller 130 will stir the various powders, so that the respective powders are mixed with each other, so that the powders can be mixed with each other during the jet process, thereby improving the mixing speed of the powders.

[0028] In some embodiments, the mixing assembly 100 further includes a second impeller 140 , which is rotatably built into the jet tube 120 and adjacent to the first impeller 130 .

[0029] In this embodiment, the powders are stirred in sequence by the first impeller 130 and the second impeller 140 so as to be more evenly mixed with each other.

[0030] Based on the above embodiments, in some embodiments, the second impeller 140 and the first impeller 130 rotate in opposite directions.

[0031] In this embodiment, the first impeller 130 and the second impeller 140 rotate in opposite directions, thereby causing the first impeller 130 and the second impeller 140 to stir the powder in opposite directions, thereby changing the movement trajectory of the powder, so that different types of powders can be mixed more quickly.

[0032] In some embodiments, the feeding assembly 200 further includes a stirring member 230 . The stirring member 230 is built into the storage tank 210 and is used to stir the powder in the storage tank 210 .

[0033] In this embodiment, the stirring member 230 is used to stir the powder in the storage tank 210 , thereby preventing the powder from agglomerating in the storage tank 210 .

[0034] In some embodiments, the stirring member 230 includes a stirring screw 231 and a motor 232 . The stirring screw 231 is rotatably built into the storage tank 210 , and the motor 232 drives the stirring screw 231 to rotate.

[0035] In this embodiment, the motor 232 drives the stirring screw 231 to rotate, and the rotating stirring screw 231 can stir the powder in the storage tank 210.

[0036] In some embodiments, the feed end of the powder pump 220 is connected to the bottom end of the storage tank 210 .

[0037] In this embodiment, since the feed end of the powder pump 220 is connected to the bottom end of the storage tank 210, under the action of gravity, the powder in the storage tank 210 accumulates near the feed end of the powder pump 220, so that the powder pump 220 can easily discharge the powder in the storage tank 210.

[0038] In some embodiments, a feeding port 211 is provided at the top of the storage tank 210 .

[0039] In this embodiment, the operator can add powder to the storage tank 210 through the feeding port 211 .

[0040] In some embodiments, the storage tank 210 further includes a cover plate 212 , which is detachably mounted on the feeding port 211 to open or close the feeding port 211 .

[0041] In some embodiments, the storage tank 210 is a stainless steel storage tank 210 .

[0042] In this embodiment, since the storage tank 210 is a stainless steel storage tank 210 , the storage tank 210 has sufficient corrosion resistance.

[0043] In some embodiments, the jet tube 120 has a plurality of throat portions 121 with narrowed inner diameters, and the output ends of the plurality of air pumps 110 are connected to the plurality of throat portions 121 in a one-to-one correspondence.

[0044] In this embodiment, since the inner diameter of the throat portion 121 is narrower, the air flow rate at the throat portion 121 is faster. Under the action of the Bernoulli principle, the jet tube 120 can absorb the powder into the jet tube 120 more quickly.

[0045] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail:

[0046] First, each type of powder is filled into each storage tank 210 one by one. The feed end of the powder pump 220 is connected to the storage tank 210, and the powder in the storage tank 210 is introduced into the jet tube 120 by the powder pump 220. Because the air pump 110 introduces a high-speed airflow into the jet tube 120, the high-speed airflow drives the powder to move within the jet tube 120. When the powder reaches the position of the first impeller 130 and the second impeller 140, the first impeller 130 and the second impeller 140 rotate in opposite directions, causing the first impeller 130 and the second impeller 140 to stir the powder in opposite directions. This changes the movement trajectory of the powder, allowing different types of powder to mix more quickly. As a result, the powders can be mixed together during the jet process, increasing the mixing speed of the powders.

[0047] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
