Description

Technical Field

[0001] This invention relates to the field of anhydrous sodium acetate drying technology, specifically to a drying device for anhydrous sodium acetate. Background Technology

[0002] Currently, the industrial production of anhydrous sodium acetate mostly adopts the neutralization reaction route of glacial acetic acid and liquid alkali. After the reaction liquid undergoes two impurity removal filtrations and activated carbon decolorization filtrations, a wet material of 20% to 30% is obtained. The wet material is directly sent to the drying equipment for processing to obtain the finished product. However, existing drying equipment has several drawbacks when processing filtered wet materials. First, after concentration and centrifugation, the wet materials form a large number of agglomerated clumps, and the internal moisture is encapsulated by crystal films. Therefore, the drying equipment needs to perform long-term drying processes, which reduces the drying efficiency. Second, because the production process uses batch feeding at once, the material accumulation thickness in the drying equipment reaches 30-50cm, resulting in uneven drying of the material inside the drying equipment and even causing local overheating and yellowing. To address these issues, we propose a drying equipment for anhydrous sodium acetate. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figures 1 to 4 A drying device for anhydrous sodium acetate includes a dryer body 1, with an inlet 11 and an outlet 12 respectively provided on the dryer body 1. A support frame 2 is provided on the outside of the dryer body 1 and near the inlet 11. A pretreatment shell 3 is fixedly installed on the support frame 2. The top of the pretreatment housing 3 is connected to a feeding mechanism 4, which is used to hold anhydrous sodium acetate wet material; The feeding mechanism 4 includes a material loading bin 41, a distribution pipe 42, a moving pipe 43, and a fixed sleeve 44. The material loading bin 41 is fixedly installed on the support frame 2. Multiple distribution pipes 42 are provided and are equidistantly connected at the bottom of the material loading bin 41. The bottom of the distribution pipes 42 is connected to the fixed sleeve 44. In this application, three distribution pipes 42 are preferably provided and are equidistantly connected at the bottom of the material loading bin 41. Through the multiple distribution pipes 42, the material inside the material loading bin 41 can be evenly and fully discharged. The fixed sleeve 44 is installed on the top of the pretreatment shell 3 and is connected to the pretreatment shell 3. The moving tube 43 slides through the fixed sleeve 44. The moving tube 43 is also provided with an inlet hole at the bottom of the material distribution tube 42. The fixed sleeve 44 is provided with a moving port. A moving rod 45 is also fixedly installed on the outside of the fixed sleeve 44. The moving rod 45 passes through the moving port. The other end of the moving rod 45 is also connected to a synchronous connection mechanism 46. The synchronous connection mechanism 46 is connected to the batch processing mechanism 5.

[0019] The material distribution tube 42 is L-shaped, and the bottom of the moving tube 43 is funnel-shaped with an open opening at the bottom. The pretreatment housing 3 is cylindrical, and one end of the pretreatment housing 3 has a circular opening; Specific implementation process: In this application, the anhydrous sodium acetate wet material that needs to be dried is first loaded into the material hopper 41. When the inlet of the moving pipe 43 is aligned with the bottom of the distribution pipe 42, the anhydrous sodium acetate wet material enters the moving pipe 43 through the distribution pipe 42 and then enters the pretreatment shell 3 through the moving pipe 43.

[0020] As a further supplementary explanation, the synchronous connection mechanism 46 includes a synchronous frame 461, a lifting rod 462, a limiting sleeve 463, a lifting plate 464, and a synchronous rod 465. One end of each of the multiple moving rods 45 is fixedly connected to the synchronous frame 461. The lifting rod 462 is fixedly installed at the bottom of one end of the synchronous frame 461. The limiting sleeve 463 is fixedly installed on the outside of the pretreatment housing 3. The lifting rod 462 slides through the limiting sleeve 463, and a limiting wheel is fixedly connected to the bottom of the lifting rod 462. A limiting shaft is fixedly installed on the limiting wheel. The lifting plate 464 is provided with a surrounding groove, and limiting grooves are also provided on both sides of the surrounding groove. One end of the limiting shaft is slidably connected to the limiting groove. The lifting plate 464 is fixedly sleeved on the outside of the synchronizing rod 465, and the connection position between the lifting plate 464 and the synchronizing rod 465 is offset from the center of the lifting plate 464. At the same time, in this application, the synchronizing rod 465 is connected to the batch processing mechanism 5. Specifically: When the synchronizing rod 465 is driven, it drives the lifting plate 464 to rotate. When the lifting plate 464 rotates, it limits the limiting wheel through the limiting groove. At this time, due to the limiting action between the lifting rod 462 and the limiting sleeve 463, the lifting rod 462 drives the synchronizing frame 461 to move up and down relative to the vertical plane. When the synchronizing frame 461 moves up, it drives the moving tube 43 to move relative to the fixed sleeve 44 through the moving rod 45, so that the moving tube 43 opens and closes the material distribution tube 42.

[0021] Please see Figures 5 to 16 The pretreatment shell 3 is equipped with a batch processing mechanism 5, which stirs and crushes the wet material entering the pretreatment shell 3. The bottom of the pretreatment shell 3 is connected to the discharge hopper 6, the discharge hopper 6 is connected to the intermittent discharge mechanism 7, the intermittent discharge mechanism 7 is connected to the collection hopper 8, and the collection hopper 8 is installed at the inlet 11. The bottom of the collection hopper 8 is also equipped with a solenoid valve 81. The intermittent discharge mechanism 7 is connected to the batch processing mechanism 5.

[0022] The batch processing mechanism 5 includes a rotating disk 51, an intermediate sleeve 52, a partition plate 53, a crushing component 54, and a synchronous drive component 55. The rotating disk 51 is rotatably connected to the circular opening. One end of the intermediate sleeve 52 is fixedly connected to the inner wall of the rotating disk 51. A rotating shaft 56 is also fixedly installed on the outer side of the rotating disk 51, and a transmission component 9 is connected to the rotating shaft 56. The transmission component 9 is connected to the synchronous connection mechanism 46. In this application, the rotating shaft 56 is rotatably connected to the support frame 2. As a further supplementary description, the transmission assembly 9 includes a rotating disk 91, an intermittent wheel 92, a gear transmission component 93, and a transmission motor 94. The transmission motor 94 is mounted on the support frame 2, and the output end of the transmission motor 94 is fixedly connected to the synchronizing rod 465. A transmission shaft is rotatably connected to the support frame 2, and the gear transmission component 93 is connected between the transmission shaft and the synchronizing rod 465. The rotating disk 91 is fixedly sleeved on the outside of one end of the rotating shaft 56. The rotating disk 91 is provided with multiple arc-shaped grooves, and there is also a toggle port between each pair of arc-shaped grooves. The intermittent wheel 92 is fixedly installed on the transmission shaft, and the intermittent wheel 92 is provided with a concave wheel, which is slidably connected to the arc-shaped groove. An intermittent rod is also fixedly installed on the intermittent wheel 92. Specific implementation process: When the drive motor 94 is running, it further causes the synchronizing rod 465 to rotate. When the synchronizing rod 465 rotates, it drives the drive shaft through the gear transmission component 93. At this time, the drive shaft drives the intermittent wheel 92 to rotate. When the intermittent wheel 92 rotates, it is limited by the concave wheel and arc groove on the intermittent wheel 92 until the intermittent rod rotates to the actuation port, thus realizing the function of rotating the rotating disk 91 at a certain angle. In this application, the number of arc-shaped grooves corresponds to the number of partition chambers 531. That is, when the partition chambers 531 are adjusted to the corresponding positions, the lifting rod 462, connected by the synchronous frame 461, enables the moving pipe 43 to achieve a telescopic function. At the same time as telescopic, the partition chambers 531 are changed, and the anhydrous sodium acetate wet material is controlled to feed. Until the partition chambers 531 are switched, the inlet of the moving pipe 43 is aligned with the bottom of the distribution pipe 42, so as to achieve the function of continuous and stable feeding of anhydrous sodium acetate wet material.

[0023] Multiple partition plates 53 are provided, and multiple partition plates 53 are fixedly installed around the outside of the middle sleeve 52 at equal distances. Two partition plates 53 form a partition chamber 531 between them and the pretreatment shell 3. The partition plates 53 are electric heating plates. Both sides of the partition plates 53 are uniformly coated with a polytetrafluoroethylene anti-stick coating with a thickness of 0.2mm-0.5mm. In this application, by setting the partition plates 53 as electric heating plates, the anhydrous sodium acetate wet material in the partition chamber 531 can be effectively heated during stirring, and the lumps of anhydrous sodium acetate wet material can be further crushed. Please see Figures 12 to 16 Multiple crushing components 54 are provided, and the multiple crushing components 54 are located in the partition chamber 531 respectively. The multiple crushing components 54 are connected to the intermediate sleeve 52 and the rotating disk 51. The synchronous drive component 55 is provided on the outside of the rotating disk 51, and the synchronous drive component 55 is used to synchronously drive the multiple crushing components 54. The other end of the pretreatment housing 3 is also fixedly installed with a fixing rod 57, and the intermediate sleeve 52 is rotatably sleeved on the outside of the fixing rod 57. The fixing rod 57 is also provided with multiple guides 58, and the guides 58 are connected to the crushing parts 54.

[0024] The crushing component 54 includes a rotating rod 541, a rotating sleeve 542, a rotating component 543, a stirring rod 544, and a limiting component 545. One end of the rotating rod 541 passes through the rotating disk 51 and is connected to the synchronous drive component 55. The rotating rod 541 is rotatably connected to the rotating disk 51. The other end of the rotating rod 541 extends into the compartment 531. Two protruding strips 5411 are provided on the outer side of the rotating rod 541. As a further supplementary explanation, the synchronous drive component 55 includes a drive gear, an internal gear ring, and a drive motor. There are multiple drive gears, which are respectively fixedly sleeved on the outside of one end of multiple rotating rods 541. The internal gear ring is rotatably connected to the outside of the rotating disk 51. The drive motor is fixedly mounted on the rotating disk 51 through a motor bracket, and the output end of the drive motor is fixedly connected to one of the rotating rods 541. Specifically, when multiple rotating rods 541 are driven synchronously, the drive motor runs, causing one of the rotating rods 541 to rotate. While the rotating rod 541 rotates, the corresponding drive gear rotates synchronously. While the drive gear rotates, it drives the other multiple drive gears to rotate synchronously through the internal gear ring, thus further causing the multiple rotating rods 541 to rotate.

[0025] Multiple rotating sleeves 542 are provided, and the multiple rotating sleeves 542 are equidistantly slidably sleeved on the outside of the rotating rod 541 and the two protruding strips 5411. A sealing shell 546 is rotatably sleeved on the outside of the rotating sleeve 542. The rotating component 543 is located inside the sealing shell 546. The rotating component 543 is used to drive the stirring rod 544. The rotating rod 541 is rotatably connected to the sealing shell 546. The stirring rod 544 is also provided with stirring blades. The stirring blades and the stirring rod 544 rotate synchronously to achieve the effect of fully stirring and crushing the wet anhydrous sodium acetate material. As a further supplementary explanation, the rotating component 543 includes a worm 5431 and a worm wheel 5432. The worm 5431 is fixedly sleeved on the outside of the rotating sleeve 542, and the worm wheel 5432 is meshed with the worm 5431. The worm wheel 5432 is fixedly sleeved on the outside of one end of the stirring rod 544. Thus, as the rotating rod 541 and the protruding strip 5411 rotate, they simultaneously drive multiple rotating sleeves 542 to rotate. When the rotating sleeves 542 rotate, the worm gear 5431 drives the worm wheel 5432 to rotate, further causing the stirring rod 544 to rotate relative to the sealing shell 546.

[0026] A limiting rod 547 is also fixedly installed on one side of the outer side of the sealing shell 546. Multiple limiting rods 547 are connected to limiting members 545, and limiting members 545 are connected to guide members 58.

[0027] Please see Figures 13 to 15 The limiting component 545 includes a limiting plate 5451, on which multiple limiting edges 5452 are fixedly installed, and a groove 5453 is provided at the limiting edge 5452, through which the limiting rod 547 slides.

[0028] The guide component 58 includes a fixed plate 581, a guide shaft 582, a guide seat 583, a slide rod 584, and a sliding sleeve 585. The fixed plate 581 is fixedly sleeved on the fixed rod 57. Both sides of the fixed plate 581 are provided with closed continuous corrugated grooves 5811. There are two guide shafts 582. One end of the two guide shafts 582 is slidably connected to the two continuous corrugated grooves 5811 respectively, and the two guide shafts 582 are fixedly connected to the guide seat 583. One end of the slide rod 584 is fixedly connected to the guide seat 583, and the other end of the slide rod 584 is fixedly connected to one of the limiting plates 5451. The sliding sleeve 585 passes through the intermediate sleeve 52, and the slide rod 584 and the sliding sleeve 585 are fitted together. By adopting the fitted connection method, the interior of the intermediate sleeve 52 is kept in a relatively sealed state.

[0029] Specific implementation process: In this application, while the anhydrous sodium acetate wet material inside the partition chamber 531 is being stirred, the synchronous drive component 55 operates, causing multiple rotating rods 541 to rotate. Simultaneously, the rotating rods 541 rotate, driving the stirring rod 544 to rotate via the rotating component 543. Also in this application, while the rotating disk 51 rotates relative to the interior of the pretreatment housing 3 along the rotating shaft 56, multiple guide shafts 582 move around their corresponding continuous corrugated grooves 5811. While moving, the guide seat 583 and the slide rod 584 cause the slide rod 584 to drive the limiting plate 5451 to move relative to the limiting shaft. When the limiting plate 5451 moves, the limiting shaft is further limited by the inclined groove 5453, thereby adjusting the position between the multiple sealing shells 546 and further adjusting the distance between the stirring rods 544. This allows the multiple stirring rods 544 to move closer and further apart, thereby achieving the function of extruding, stirring and crushing the blocky anhydrous sodium acetate wet material.

[0030] Example 2 Please see Figures 4 to 8 Example 2 is a further supplementary description of Example 1. Specifically, the intermittent discharge mechanism 7 includes a horizontal pipe 71, a vertical pipe 72, a discharge piston 73, and a mating component 74. The horizontal pipe 71 is connected to the bottom of the discharge hopper 6, and one end of the horizontal pipe 71 is connected to the vertical pipe 72. The vertical pipe 72 is installed on the top of the collection hopper 8. The discharge piston 73 is mated inside the horizontal pipe 71, and a collection hole 731 is opened on the discharge piston 73. The mating component 74 is located at the end of the discharge piston 73 away from the vertical pipe 72, and the mating component 74 is connected to the transmission assembly 9. The mating component 74 includes a mating rod 741, a mating disc 742, and a mating shaft 743. The mating rod 741 is fixedly installed at one end of the discharge piston 73, and the mating shaft 743 is fixedly installed at one end of the mating rod 741. The mating disc 742 is fixedly sleeved on the outside of one end of the synchronizing rod 465, and the position where the mating disc 742 is connected to the synchronizing rod 465 is off-center. The mating disc 742 is provided with a reciprocating groove 7421, and one end of the mating shaft 743 is slidably connected to the reciprocating groove 7421. The specific implementation process is as follows: When the synchronizing rod 465 rotates, the mating disc 742 rotates synchronously. As the mating disc 742 rotates, it drives the mating shaft 743 through the reciprocating groove 7421. Because the mating shaft 743 is limited by the discharge piston 73 and the transverse tube 71, the mating rod 741 drives the discharge piston 73 to reciprocate laterally relative to the transverse tube 71, so as to intermittently introduce the pretreated anhydrous sodium acetate material collected at the collection hole 731 into the collection hopper 8. After a certain amount of material is collected in the collection hopper 8, or after a certain time is set, the solenoid valve 81 opens, thereby introducing a certain amount of pretreated anhydrous sodium acetate material into the dryer body 1, so as to achieve further thorough and efficient drying of anhydrous sodium acetate.
