[0002] Soda ash (sodium carbonate), commonly known as soda ash, also known as soda and soda ash, is an important basic chemical raw material. Soda ash has a wide range of uses, generally utilizing its alkalinity. It can be used to make glass, such as flat glass, optical glass and high-end utensils. It can also be used to make soap by the reaction of fatty acids and soda ash. When soda ash is exposed to the outside world, it easily absorbs moisture in the air due to its own characteristics. When producing soda ash, it is necessary to use a drying device to dry the soda ash and then seal it for storage to prevent the moisture absorbed by the soda ash from affecting the quality.

[0003] For example, the patent with the announcement number CN222257521U discloses an environmentally friendly soda ash drying device, including a crushing mechanism, the crushing mechanism includes a feeding shell, one side of the feeding shell is adapted to be installed with a conveying motor, and the output end of the conveying motor is fixedly installed with a feeding roller, two extrusion plates move relative to each other to perform crushing treatment, and under the action of the distribution plate, the soda ash accumulated after crushing is pushed away, at this time, the operation of the telescopic cylinder is controlled, the telescopic cylinder drives the slide bar to move in the U-shaped frame, the slide bar drives the connecting block to move, and the connecting block drives the equal-dividing scraper to move, and the soda ash pushed away by the distribution plate is divided again, and under the action of the telescopic cylinder, the required thickness of the soda ash drying can be adjusted to make it more evenly heated, and under the action of the crushing mechanism, the large pieces of soda ash that appear can be crushed, so that the soda ash can be evenly heated during the drying process. However, the existing drying device directly piles up a large amount of soda ash in the heat preservation cover after crushing and drying, and it is difficult to make it fully and quickly heated and dried by relying solely on the distribution plate to turn the material.

[0004] Therefore, an air flow drying device for producing light soda ash is introduced. Summary of the invention

[0031] In order to solve the problem that when the existing drying device crushes soda ash and accumulates it in the heat preservation cover for feeding and drying, the uneven heat drying effect of the soda ash by the fluctuating turning of the dividing plate is not ideal, please refer to Figures 1 - 7 , the following preferred technical solutions are provided:

[0032] The bottom of the blanking box cover 2 is fixedly connected with a spiral blanking pipe 3. Both sides of the top of the spiral blanking pipe 3 are fixedly connected with fixing rods. The spiral blanking pipe 3 is fixedly suspended at the bottom of the shell cylinder 21 through the fixing rods. And the spiral blanking pipe 3 is a component made of copper material. The bottom of the spiral blanking pipe 3 is fixedly connected with spray pipes 31 at equal intervals. The spray pipes 31 are all one-way discharge pipes. The top of the outer side of the spiral blanking pipe 3 is fixedly connected with a communicating pipe 32. The communicating pipe 32 is communicated with the inner cavity of the blanking box cover 2. On the bottom plate of the drying tank 1, a motor 11 and a hot air blower 14 are fixedly connected. The output end of the top of the motor 11 is fixedly connected with a hollow rotating shaft 12. An axially connected sleeve 13 is movably sleeved on the outer wall of the hollow rotating shaft 12. One outer wall of the sleeve 13 is connected with the air outlet cylinder of the hot air blower 14. The top of the hollow rotating shaft 12 is fixedly connected with a hollow air distribution disc 16 which is axially connected. The hollow air distribution disc 16 is movably clamped between the inner walls of the drying tank 1. The side wall of the hollow air distribution disc 16 is in interference fit with the inner wall of the drying tank 1. And the top of the hollow air distribution disc 16 is provided with air spray holes 161 at equal intervals. Between the inner walls of the ports of the air spray holes 161, a cross-opening sealing gasket is fixedly connected. And the air spray holes 161 are one-way air outlet holes (prior art). On both sides of the top of the hollow air distribution disc 16 outside the air spray holes 161, auxiliary air pipes 4 are respectively fixedly connected. On the opposite side walls of the auxiliary air pipes 4, air jet branch pipes 5 are fixedly connected at equal intervals. On one outer wall of the drying tank 1, an air extraction fan 7 is fixedly connected. The top of the air extraction fan 7 is fixedly connected with an air outlet pipe 8. An electric exhaust valve is arranged on one outer wall of the air outlet pipe 8. The end of the air outlet pipe 8 penetrates through the side wall of the drying tank 1 and is fixedly connected with the outer wall of the port of the outer side end of the spiral blanking pipe 3. The communicating pipe 32 is fixedly connected at the top adjacent to the contact end of the spiral blanking pipe 3 and the air outlet pipe 8. The port at the center of the spiral blanking pipe 3 is arranged vertically downward. The bottom of the air extraction fan 7 is fixedly connected with an air extraction pipe 9. The end of the air extraction pipe 9 penetrates through and extends into the drying tank 1. The inlet end of the air extraction pipe 9 is flush with the inner wall of the drying tank 1. A filter screen is arranged between the inner walls of the inlet end of the air extraction pipe 9. The filter screen is arranged in a manner of fitting the outer wall of the auxiliary air pipe 4. An activated carbon dehumidification plate is movably inserted between the inner walls of the air extraction pipe 9 on one side of the filter screen. One end of the activated carbon dehumidification plate extends to the outside of the air extraction pipe 9 and can be disassembled and replaced.

[0033] Between the inner walls of the drying tank 1 outside the sleeve 13, an annular plate 15 is fixedly connected. The annular plate 15 is located below the hollow air distribution disc 16. And at equal intervals, balls are movably embedded at the lower end of the bottom plate of the hollow air distribution disc 16. The lower ends of the balls are movably attached to the top surface of the annular plate 15. On the side wall of the drying tank 1 on one side of the top surface of the hollow air distribution disc 16, a discharge valve pipe 10 is arranged.

[0034] A hollow cavity 121 is arranged inside the hollow rotating shaft 12. The hollow cavity 121 is communicated with the inner cavity of the hollow air distribution disc 16. Air inlet openings 122 are arranged at equal intervals on the side wall of the hollow cavity 121. The sleeve 13 is movably sleeved on the outer wall of the hollow rotating shaft 12 outside the air inlet openings 122.

[0035] The bushing 13 includes a sealing sleeve 131 movably sleeved on the outer wall of the hollow rotating shaft 12 outside the air inlet 122, and a connector 132 fixedly connected to the outer wall of one side of the sealing sleeve 131. The end of the connector 132 is fixedly connected and communicated with the end of the air outlet cylinder of the hot air blower 14.

[0036] Specifically, the light soda ash to be dried is poured through the top port of the blanking box cover 2, so that the light soda ash inside the blanking box cover 2 slides down through the connecting pipe 32 to the inside of the inlet end of the spiral blanking pipe 3. Start the motor 11 and the hot air blower 14. The motor 11 drives the hollow air distribution disc 16 to rotate by means of the hollow rotating shaft 12. At the same time, the hot air flow ejected by the hot air blower 14 is introduced into the inside of the hollow air distribution disc 16 through the bushing 13 and the hollow rotating shaft 12. When the hollow air distribution disc 16 rotates, it ejects a uniform rotating air flow into the spiral blanking pipe 3 through the air injection holes 161. At the same time, the air extraction fan 7, in cooperation with the air extraction pipe 9 and the air outlet pipe 8, circulates and introduces a part of the air flow inside the drying tank 1 into the spiral blanking pipe 3. This air flow pushes the light soda ash that has fallen into the inside of the inlet end of the spiral blanking pipe 3 to slide along the inside of the spiral blanking pipe 3, thereby driving the light soda ash accumulated in the blanking box cover 2 to uniformly circulate into the spiral blanking pipe 3 at a constant speed. When the air flow pushes the light soda ash to slide along the inside of the spiral blanking pipe 3, it preheats the light soda ash synchronously. The air flow pushes the light soda ash in the spiral blanking pipe 3 to continuously eject from the spray pipes 31 at different positions at the bottom of the spiral blanking pipe 3. The air flow continuously ejected from the spray pipes 31 forms a convective impact with the rotating air flow ejected by the hollow air distribution disc 16, so that the light soda ash ejected from the spiral blanking pipe 3 is suspended in the drying tank 1. At the same time, the rotating air flow ejected by the hollow air distribution disc 16 drives the suspended light soda ash to float and rotate. At this time, the hollow air distribution disc 16 uses the auxiliary air pipe 4 and the air injection branch pipe 5 to eject a transverse disturbance air flow to the suspended light soda ash in a rotating manner, so that the part of the suspended light soda ash that gathers at the inner wall of the drying tank 1 due to the centrifugal force of the rotating air flow moves back towards the inner circle, realizing the full and effective contact between the suspended light soda ash and the hot air flow, thereby ensuring the rapid drying effect of the light soda ash and being convenient to use.

[0037] As Figure 4 and Figure 5 As shown, ultrasonic vibrators 27 are uniformly and spacedly fixedly connected to the bottom of the shell cylinder 21 corresponding to the spiral blanking pipe 3. The ultrasonic vibrators 27 are suspended outside the fixed rod, and the lower ends of the ultrasonic vibrators 27 are arranged in contact with the top of the spiral blanking pipe 3. And ultrasonic sensors 33 are uniformly and spacedly fixedly connected to the top of the spiral blanking pipe 3 outside the spray pipes 31.

[0038] Specifically, the ultrasonic sensor 33 is used to monitor the flow state of light soda ash inside the spiral feeding pipe 3 and the pressure change inside the pipe in real time. Once it is found that there are signs of material accumulation and blockage, the ultrasonic vibrator 27 is started. The ultrasonic vibrator 27 uses the emitted ultrasonic waves to ultrasonically crush the accumulated and blocked materials in the ultrasonic sensor 33, so that the light soda ash inside the spiral feeding pipe 3 can flow smoothly under the push of the air flow.

[0039] As Figure 2 , Figure 3 and Figures 8 - 9 shown, in order to further enhance the contact drying effect between soda ash and hot air flow, the present embodiment provides the following preferred technical solutions:

[0040] An auxiliary member 6 is fixedly connected to the outer wall of the auxiliary air duct 4 between the jet branch pipes 5, and the ends of the auxiliary members 6 on the outer walls of the auxiliary air ducts 4 on both sides of the top of the hollow air distribution plate 16 are close to each other.

[0041] The auxiliary member 6 includes a Y-shaped rod 61 fixedly connected to the outer wall of the auxiliary air duct 4 between the jet branch pipes 5. The end outer walls of the two side struts of the Y-shaped rod 61 are respectively rotatably connected with a positioning rod 62. A positioning ring 63 is fixedly connected to the end outer wall of the positioning rod 62. An annular groove 64 is formed in the inner wall of the positioning ring 63. A T-shaped rod 65 is movably clamped between the inner walls of the annular groove 64. A reinforcing rod 66 is fixedly connected to the bottom of the vertical rod of the T-shaped rod 65. A crushing ball 67 is fixedly connected to the bottom of the reinforcing rod 66.

[0042] The crushing ball 67 includes a metal shell 671 fixedly connected to the bottom of the reinforcing rod 66. An installation cavity is arranged inside the metal shell 671. Arc-shaped elastic members 672 are evenly and spacedly fixedly connected to the inner wall of the installation cavity. A counterweight ball 673 is freely placed inside the installation cavity outside the arc-shaped elastic members 672.

[0043] Specifically, when the light soda ash ejected from the spiral feeding pipe 3 is suspended in the drying tank 1, the reinforcing rod 66 and the crushing balls 67 are suspended among the suspended light soda ash. When the hollow air distribution plate 16 rotates, the auxiliary air pipe 4 is used to drive the Y-shaped rod 61 to drive the crushing balls 67 to swing. Due to the eccentric suspension setting of the crushing balls 67 and the centrifugal force of the rotation of the hollow air distribution plate 16, the positioning rod 62 is pushed to automatically rotate longitudinally based on the Y-shaped rod 61, or the T-shaped rod 65 is pushed to rotate horizontally in the annular groove 64 of the positioning ring 63. Finally, the crushing balls 67 are pushed to drive the reinforcing rod 66 to drive the crushing balls 67 to swing continuously in an indefinite direction. When the adjacent crushing balls 67 swing and collide with each other, the suspended light soda ash is impacted and crushed, further refining the agglomerated light soda ash crushed by the feeding box cover 2, thereby increasing the contact area between the light soda ash and the hot air flow to improve the drying effect thereof. After the adjacent crushing balls 67 collide, the counterweight balls 673 inside the metal shell 671 are driven to impact the arc-shaped elastic member 672. The arc-shaped elastic member 672 rebounds the counterweight balls 673 in an indefinite direction to impact the metal shell 671 again, further causing the crushing balls 67 to collide with other adjacent crushing balls 67, thereby ensuring the impact crushing effect on the suspended light soda ash, and further promoting the contact drying effect between the suspended light soda ash and the hot air flow, which is convenient and practical.
