Technical Field

[0001] The present invention relates to the field of stirring and mixing equipment, in particular to a chemical powder stirring and mixing equipment. Background Art

[0002] Mixing two different materials is a common operation in the chemical industry. Different chemical material forms result in different mixing effects. For granular materials, which have good flowability, conventional mixing equipment can achieve the required mixing, as shown in Patent Publication No. CN217341160U, entitled Chemical Material Mixing and Stirring Equipment with Grinding Function. However, for powdered materials, due to their poor flowability and the tendency to form a collapse angle, conventional mixing equipment cannot meet the requirements. Summary of the Invention

DETAILED DESCRIPTION

[0024] The following combination Figures 1 to 7 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] A chemical powder mixing device comprises two air separation devices 1, a material barrel 6 and an air outlet box 9.

[0026] The air separation equipment 1 includes an air separation channel 2 and a turbine fan 3. The air separation channel 2 includes two vertically identical parts, and the turbine fan 3 is arranged between the two vertically intersecting parts of the air separation channel 2. The two ends of the air separation channel 2 serve as the material inlet and the material outlet respectively. The material inlet is connected to a vibrating screen 14 for feeding materials into the air separation equipment 1. The material outlet is close to the barrel 6 and consists of a first guard plate 11 and a second guard plate 12. The first guard plate 11 and the second guard plate 12 are cylindrical, and the first guard plate 11 is arranged inside the second guard plate 12 and coaxially. A first outlet 4 is formed in the first guard plate 11, and a second outlet 5 is formed between the first guard plate 11 and the second guard plate 12. The first outlet 4 is close to the center of the air separation channel 2, and the second outlet 5 is close to the edge of the air separation channel 2. A baffle 13 is rotatably connected in the air separation channel 2, and the baffle 13 is divided into two pieces. The baffles 13 are provided with a rotating shaft 24. The rotating shafts 24 of the two baffles 13 are connected by a connecting rod 25 to ensure simultaneous rotation of the two baffles 13. One of the baffles 13 is driven to rotate by a second driver 26. The rotation of the two baffles 13 can block or open the air separation channel 2. The turbo blower 3 is used to create a negative pressure environment in the air separation channel 2, thereby blowing the material from the material inlet to the material outlet.

[0027] The barrel 6 includes a first barrel 15 and a second barrel 16 which are concentrically sleeved. The inner cavity of the first barrel 15 is a first chamber 7. The outer wall of the first barrel 15 and the inner wall of the second barrel 16 form a second chamber 8. The first chamber 7 is connected to the first outlet 4, and the second chamber 8 is connected to the second outlet 5. An arc-shaped guide plate 20 is provided on the top of the first barrel 15, and the guide plate 20 is bent toward the material outlet. A partition 21 is provided in the second chamber 8, and the partition 21 separates the second chamber 8 into a first accommodating chamber 22 and a second accommodating chamber 23. The material outlets of the two air separation devices 1 are respectively connected to the first accommodating chamber 22 and the second accommodating chamber 23. The partition 21 can prevent the two air separation devices 1 from blowing against each other and affecting their discharge. The guide plate 20 should be provided above the first outlet 4 and the second outlet 5. A first driver 17 is provided below the barrel 6. The output end of the first driver 17 is connected to a stirring rod 18. The stirring rod 18 is connected to two sets of stirring blades 19. One set of stirring blades 19 is rotatably connected to the bottom of the first barrel 15, and the other set of stirring blades 19 is rotatably connected to the bottom of the second barrel 16. A discharge port 27 is provided at the bottom of each of the first barrel 15 and the second barrel 16.

[0028] The air outlet box 9 is fixedly connected to the top of the barrel 6, and a bag cage 10 is provided in the air outlet box 9 to prevent material discharge from polluting the workshop environment.

[0029] When using the powder mixing equipment, the turbine blower 3 blows the material into a suspended state. Small, light-weight materials experience low centrifugal force and enter the first chamber 7 through the first outlet 4. Large, heavy materials experience high centrifugal force and enter the second chamber 8 through the second outlet 5. Small-particle materials have poor fluidity and, after exiting the first outlet 4, self-mix in a suspended state. After settling, they are then stirred and mixed with assistance by the stirring blades 19. Large-particle materials have good fluidity and are directly stirred and mixed by the stirring blades 19.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
