Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to an airflow drying device for producing light soda ash. Background Art

[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

[0021] In order to solve the problem that when the existing drying device crushes the soda ash and piles it in the heat preservation cover for material drying, the swing of the distribution plate turns the material, which makes the uniform heating and drying effect of the soda ash unsatisfactory. Figure 1-Figure 7 , provide the following preferred technical solutions: A spiral feeding tube 3 is fixedly connected to the bottom of the feeding box cover 2, and fixed rods are fixedly connected to both sides of the top of the spiral feeding tube 3. The spiral feeding tube 3 is fixedly suspended at the bottom of the shell tube 21 through the fixed rods, and the spiral feeding tube 3 is a component made of copper material. The bottom of the spiral feeding tube 3 is evenly and fixedly connected with spraying pipes 31 at intervals, and the spraying pipes 31 are all one-way discharge pipes.

The outer wall of one side of the shaft sleeve 13 is connected to the air outlet of the hot air blower 14. The top of the hollow rotating shaft 12 is fixedly connected with a connected hollow air distribution disk 16, which is movably engaged between the inner walls of the drying tank 1. The side walls of the hollow air distribution disk 16 and the inner wall of the drying tank 1 are interference fit, and the top of the hollow air distribution disk 16 is evenly spaced with jet holes 161, and a cross-opening seal is fixedly connected between the inner walls at the ports of the jet holes 161. The pad is provided, and the jet hole 161 is a one-way air outlet (existing technology). The two sides of the top of the hollow air distribution plate 16 outside the jet hole 161 are respectively fixedly connected with auxiliary air ducts 4, and the side walls opposite to the auxiliary air duct 4 are evenly fixedly connected with jet branch pipes 5. An exhaust fan 7 is fixedly connected to the outer wall of one side of the drying tank 1, and an exhaust pipe 8 is fixedly connected to the top of the exhaust fan 7. An electric exhaust valve is arranged on the outer wall of one side of the exhaust pipe 8. The end of the exhaust pipe 8 passes through the side wall of the drying tank 1 and is fixedly connected to the outer wall of the outer end of the spiral feeding pipe 3. The connecting pipe 32 is fixedly connected to the outer wall of the outer end of the spiral feeding pipe 3. It is connected to the top of the place where the spiral feeding pipe 3 and the air outlet pipe 8 contact each other. The port at the center of the spiral feeding pipe 3 is arranged vertically downward. The bottom of the exhaust fan 7 is fixedly connected with an exhaust pipe 9. The end of the exhaust pipe 9 extends through the drying tank 1. The inlet end of the exhaust pipe 9 is flush with the inner wall of the drying tank 1. A filter is arranged between the inner walls of the inlet end of the exhaust pipe 9. The filter is arranged to fit the outer wall of the auxiliary air duct 4. An activated carbon dehumidification plate is movably inserted between the inner walls of the exhaust pipe 9 on one side of the filter. One end of the activated carbon dehumidification plate extends to the outside of the exhaust pipe 9 and can be disassembled and replaced.

[0022] An annular plate 15 is fixedly connected between the inner wall of the drying tank 1 outside the sleeve 13, and the annular plate 15 is located below the hollow air distribution disk 16, and balls are movably embedded at evenly spaced intervals on the lower end of the bottom plate of the hollow air distribution disk 16, and the lower ends of the balls are movably fitted into the top surface of the annular plate 15, and a discharge valve pipe 10 is provided on the side wall of the drying tank 1 on one side of the top surface of the hollow air distribution disk 16.

[0023] A hollow cavity 121 is provided inside the hollow rotating shaft 12 , and the hollow cavity 121 is communicated with the inner cavity of the hollow air distribution plate 16 . Air inlets 122 are evenly spaced on the side wall of the hollow cavity 121 , and a shaft sleeve 13 is movably sleeved on the outer wall of the hollow rotating shaft 12 outside the air inlet 122 .

[0024] The shaft sleeve 13 includes a sealing sleeve 131 movably sleeved on the outer wall of the hollow shaft 12 outside the air inlet 122 and an adapter 132 fixedly connected to the outer wall of one side of the sealing sleeve 131. The end of the adapter 132 is fixedly connected and communicated with the end of the air outlet of the hot air blower 14.

[0025] Specifically, the light soda ash to be dried is poured in through the top port of the discharge box cover 2, and then the light soda ash inside the discharge box cover 2 slides into the inlet end of the spiral discharge pipe 3 through the connecting pipe 32, and the motor 11 and the hot air blower 14 are started. The motor 11 drives the hollow air distribution plate 16 to rotate by using the hollow rotating shaft 12. At the same time, the hot air flow ejected by the hot air blower 14 is introduced into the hollow air distribution plate 16 through the shaft sleeve 13 and the hollow rotating shaft 12. When the hollow air distribution plate 16 rotates, a uniform rotating air flow is ejected to the spiral discharge pipe 3 by using the air jet hole 161. At the same time, the exhaust fan 7 cooperates with the exhaust pipe 9 and the air outlet pipe 8 to circulate part of the air flow inside the drying tank 1 into the spiral discharge pipe 3. This air flow pushes the light soda ash falling into the inlet end of the spiral discharge pipe 3 to slide along the inside of the spiral discharge pipe 3, thereby driving the light soda ash accumulated in the discharge box cover 2 to circulate into the spiral discharge pipe 3 at a uniform speed. The airflow pushes the light soda ash to slide along the inside of the spiral feeding pipe 3, and it is preheated simultaneously. The airflow pushes the light soda ash in the spiral feeding pipe 3 to be continuously sprayed out from the spray pipes 31 at different positions on the bottom of the spiral feeding pipe 3. The airflow continuously sprayed out of the spray pipe 31 and the airflow rotated and sprayed out by the hollow air distribution disk 16 form a convection impact, so that the light soda ash sprayed out of the spiral feeding pipe 3 is suspended in the drying tank 1. At the same time, the rotating airflow sprayed out of the hollow air distribution disk 16 drives the suspended light soda ash to float and rotate. At this time, the hollow air distribution disk 16 uses the auxiliary air duct 4 to cooperate with the jet branch pipe 5 to rotate and spray the suspended light soda ash to laterally disturb the airflow, so that the part of the suspended light soda ash gathered on the inner wall of the drying tank 1 due to the centrifugal force of the rotating airflow moves toward the inner circle again, thereby achieving full and effective contact between the suspended light soda ash and the hot airflow, thereby ensuring the rapid drying effect of the light soda ash and convenient use.

[0026] like Figure 4 and Figure 5 As shown, ultrasonic vibrators 27 are evenly spaced and fixedly connected at the bottom of the shell tube 21 corresponding to the spiral feeding pipe 3. The ultrasonic vibrators 27 are suspended on the outside of the fixed rod, and the lower end of the ultrasonic vibrator 27 is arranged in contact with the top of the spiral feeding pipe 3, and ultrasonic sensors 33 are evenly spaced and fixedly connected to the top of the spiral feeding pipe 3 outside the spray pipe 31.

[0027] Specifically, the ultrasonic sensor 33 is used to monitor in real time the flow state of the light soda ash inside the spiral feeding pipe 3 and the pressure changes in the pipeline. Once signs of accumulation and blockage of the material are found, the ultrasonic vibrator 27 is started. The ultrasonic vibrator 27 uses the ultrasonic wave to ultrasonically break up the accumulated and blocked material 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 airflow.

[0028] like Figure 2 , Figure 3 and Figure 8-Figure 9 As shown, in order to further enhance the contact drying effect between soda ash and hot air flow, this embodiment provides the following preferred technical solutions: An auxiliary component 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 components 6 on the outer walls of the auxiliary air duct 4 on both sides of the top of the hollow air distribution plate 16 are close to each other.

[0029] The auxiliary component 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, and positioning rods 62 are rotatably connected to the outer walls of the ends of the support rods on both sides of the Y-shaped rod 61. A positioning ring 63 is fixedly connected to the outer wall of the end of the positioning rod 62. An annular groove 64 is provided on the inner wall of the positioning ring 63. A T-shaped rod 65 is movably engaged 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, and a crushing ball 67 is fixedly connected to the bottom of the reinforcing rod 66.

[0030] The crushing ball 67 includes a metal shell 671 fixedly connected to the bottom of the reinforcing rod 66. An installation cavity is provided inside the metal shell 671. Arc-shaped elastic components 672 are evenly spaced and 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 component 672.

[0031] Specifically, when the light soda ash sprayed out by the spiral discharge pipe 3 is suspended in the drying tank 1, the reinforcing rod 66 and the crushing ball 67 are suspended between the suspended light soda ash, and when the hollow air distribution plate 16 rotates, the auxiliary air duct 4 is used to drive the Y-shaped rod 61 to drive the crushing ball 67 to swing. The crushing ball 67 is driven by the eccentric suspension setting and the centrifugal force of the rotation of the hollow air distribution plate 16 to push the positioning rod 62 to automatically rotate longitudinally based on the Y-shaped rod 61, or push the T-shaped rod 65 to rotate horizontally in the annular groove 64 of the positioning ring 63, so that the crushing ball 67 finally pushes the reinforcing rod 66 to drive the crushing ball 67 to swing continuously in an undirected manner. When adjacent crushing balls 67 swing and collide with each other, the suspended The floating light soda ash is impacted and crushed, and the agglomerated light soda ash crushed by the discharge box cover 2 is further refined, thereby increasing the contact area between the light soda ash and the hot air flow to improve the drying effect. After the adjacent crushing balls 67 collide, the weighted ball 673 inside the metal shell 671 is lifted up to impact the arc-shaped elastic component 672. The arc-shaped elastic component 672 rebounds the weighted ball 673 in an undirected manner to make it impact the metal shell 671 again, and further causes the crushing ball 67 to collide with other adjacent crushing balls 67, thereby ensuring the impact and crushing effect of the suspended light soda ash, and then fully promoting the contact and drying effect between the suspended light soda ash and the hot air flow, which is convenient and practical.
