Description

Technical Field

[0001] The invention relates to the technical field of sodium acetate production, in particular to temperature-controlled dust-free conveying equipment for sodium acetate. Background Art

[0002] Sodium acetate, also known as sodium acetate, is a common organic compound, usually present as sodium acetate trihydrate. It is a colorless, transparent crystal or white granule, readily soluble in water and slightly soluble in ethanol. Anhydrous sodium acetate is a colorless, transparent crystal with a melting point of 324°C. Sodium acetate is hygroscopic and readily deliquesces in air.

[0003] The production of sodium acetate primarily involves three steps: reaction, crystallization, and drying. The drying temperature for sodium acetate should be kept within a reasonable range, typically around 120°C. Excessively high temperatures can cause sodium acetate to decompose, affecting product quality. After drying, the solid sodium acetate is conveyed using a sealed conveyor belt or screw conveyor to minimize dust.

[0004] During transportation, attention must be paid to the sealing of the conveying device and temperature control during transportation. For sealed conveying devices, sodium acetate will be shaken and dispersed during transportation, causing the heat trapped in it to dissipate. Heat accumulates in the closed device and cannot be evacuated in time, causing localized excessive temperatures within the device, thus affecting the quality of the sodium acetate.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-11 The present invention provides a technical solution: a temperature-controlled dust-free conveying device for sodium acetate, comprising a spiral conveying mechanism 1 and a regulating mechanism 2. The spiral conveying mechanism 1 comprises a cover plate 3, on which a plurality of heat dissipation windows 31 are spaced apart. A dredging plate 4 is mounted on the heat dissipation window 31, and the dredging plate 4 is provided with a plurality of mesh holes 41. The regulating mechanism 2 comprises a plurality of collection boxes 5 arranged corresponding to the heat dissipation windows 31.

[0033] like Figure 4 、 Figure 5 As shown, a sponge 51 is provided in the collecting box 5, and a splint 52 is provided on one side of the collecting box 5. The splint 52 is arranged in a Z-shaped structure. A hollow cavity 521 is provided inside the splint 52 and several suction ports 522 are opened on the side facing the sponge 51. A partition plate 53 is provided in the hollow cavity 521. The side of the partition plate 53 facing the suction port 522 is an output area 531, and the side of the partition plate 53 facing away from the suction port 522 is an input area 532. The output area 531 and the input area 532 are respectively connected to a pump body 1 54 and a pump body 2 55.

[0034] Supplementary explanations based on the above structure are as follows: Preferably, a filter membrane is provided on the mesh 41 to prevent the sodium acetate transported inside the spiral conveying mechanism 1 from overflowing. The spiral conveying mechanism 1 is used to transport solid sodium acetate. During the transportation process, the sodium acetate will be constantly stirred and broken up, during which time the heat contained inside will rise upward, and the hot gas will penetrate through the dredging plate 4 into the collection box 5. During this process, water vapor and condensed liquid are absorbed by the sponge 51. Pump body 1 54 extracts a gas-liquid mixture from the sponge 51 through the suction port 522. The gas-liquid mixture passes through the output area 531, and pump body 2 55 delivers gas to the sponge 51 through the suction port 522 to balance the internal pressure. The collection box 5 thus absorbs the excess heat accumulated by the spiral conveying mechanism 1, condenses and collects the water vapor in the heat, and then returns the dried gas after the temperature has been reduced, thereby improving the quality of sodium acetate transportation without compromising the internal pressure.

[0035] Further, such as Figure 6As shown, a tooth groove 523 is provided on the upper surface of the splint 52, and a rack 61 is provided in cooperation with the tooth groove 523. A fixed plate 62 is provided for sliding cooperation with the rack 61. Brackets 63 are connected to both sides of the fixed plate 62. The brackets 63 are connected and fixed to the cover plate 3. A screw 64 is passed through the middle of the rack 61 and is threadedly engaged with it. One end of the screw 64 is connected to a motor 65, and the motor 65 is fixed on the cover plate 3.

[0036] In actual operation, rack 61 is provided with slots on both sides, and fixed plate 62 is equipped with blocks that match the slots. When motor 1 65 controls the rotation of screw 64, rack 61 moves forward or backward along the direction of screw 64. When rack 61 moves, the tooth groove 523 of rack 61 cooperates with it, driving clamp 52 to move accordingly, thereby adjusting the position of clamp 52 within collection box 5. Clamp 52 is pressed against sponge 51, making it easier for absorbed water to be discharged.

[0037] In one embodiment, Figure 7 As shown, a diversion box 7 is provided on the fixed plate 62 , and the diversion box 7 corresponds to each collecting box 5 , and one end of the pump body 1 54 and the pump body 2 55 are respectively connected to the diversion box 7 .

[0038] like Figure 8 、 Figure 9 As shown, a compartment 71 is provided at the interface position of the diverter box 7 relative to the pump body 54, a slide groove 711 is provided on the upper side of the compartment 71, a frame 72 is fixed to the bottom of the slide groove 711, the middle part of the frame 72 is open, and a spring 73 is connected to the position of the frame 72 corresponding to the slide groove 711. A pressure sensing module is provided at the connection between the frame 72 and the spring 73, and the other end of the spring 73 is connected to a grille plate 74, and a plurality of grille holes 741 are opened on the grille plate 74.

[0039] Further, such as Figure 10 As shown, a liquid outlet 712 is provided on one side of the compartment 71. The height of the liquid outlet 712 is lower than the bottom of the frame 72 to ensure that the liquid can flow out naturally. The liquid outlet 712 is connected to the cooling channel 75. The cooling channel 75 has an annular structure and the outlet end is connected to the inside of the diversion box 7. A liquid level detection module and a temperature detection module are provided in the diversion box 7.

[0040] Furthermore, Figure 7 As shown, a gas outlet 713 is provided on one side of the compartment 71 . The height of the gas outlet 713 is higher than the height of the upper surface of the grid plate 74 . The gas outlet 713 is connected to an annular pipeline 76 , and the other end of the annular pipeline 76 is connected to the pump body 2 55 .

[0041] A three-way valve 8 is provided on the connection route between the pump body 1 54 and the output area 531 , and another interface of the three-way valve 8 is connected to the inside of the diversion box 7 .

[0042] It should be noted that the gas flow route is configured to start from the collection box 5, pass through the output area 531, and reach compartment 71. It is then separated from the liquid being transported along with it, and then transported by pump body 2 55 to the input area 532 via annular pipe 76, and ultimately returned to the collection box 5. The liquid flow route is configured to start from the collection box 5, pass through the output area 531, and reach compartment 71. After separation from the gas, the liquid is temporarily stored in compartment 71. When the liquid in compartment 71 reaches a certain level, it enters the cooling channel 75 and ultimately flows into the diverter box 7. The three-way valve 8 is used to control the opening and closing states of the three ports, thereby changing the input source of pump body 1 54.

[0043] like Figure 11 As shown, the cover plate 3 is connected to the housing 11 , a material inlet 12 is provided on the upper side of the cover plate 3 , and a material outlet 13 is provided on the lower side of the housing 11 .

[0044] A rotating shaft 14 is rotatably provided inside the housing 11 , a spiral blade 15 is fixed on the surface of the rotating shaft 14 , and one end of the rotating shaft 14 extends out of the surface of the housing 11 and is connected to a second motor 16 .

[0045] In actual operation, sodium acetate enters the housing 11 from the material inlet 12 , and the motor 2 16 controls the rotation of the shaft 14 to rotate the spiral blade 15 , driving the sodium acetate to move toward the material outlet 13 and be delivered from the material outlet 13 .

[0046] The specific implementation methods are as follows:

[0047] The sodium acetate transportation process is as follows: after production, sodium acetate enters the screw conveying mechanism 1 through the conveying pipeline. The screw conveying mechanism 1 conveys sodium acetate at a certain rate and turns it over. During this process, the regulating mechanism 2 is used to collect the hot air emitted from the sodium acetate to avoid excessive heat accumulation inside the screw conveying mechanism 1. Then, the sodium acetate is output from the outlet of the screw conveying mechanism 1.

[0048] The normal mode process of control mechanism 2 is as follows: When sodium acetate is normally conveyed within screw conveyor mechanism 1, internal hot air rises into collection box 5, where it is captured and absorbed by sponge 51, prompting pump body 1 54 to activate. Under normal conditions, clamping plate 52 is in close contact with the inner wall of collection box 5, and sponge 51 is in contact with suction port 522 of clamping plate 52. When pump body 1 54 is in the extraction mode, the hot air absorbed within sponge 51 is transferred to output area 531 and then to compartment 71. During this process, the temperature of the hot air decreases. The air entering compartment 71 passes through annular conduit 76, further lowering its temperature. Annular conduit 76 is angled toward gas outlet 713. During the cooling process, if condensation is generated, the liquid will flow back into compartment 71 along the inclination; the gaseous portion continues along the conduit and is ultimately pumped back into collection box 5 by second pump body 55. The lowered temperature of the returned air effectively lowers the temperature within screw conveyor mechanism 1, preventing localized overheating that could cause sodium acetate decomposition.

[0049] Based on the above process, the positions of the pressure sensing modules are marked: the pressure sensing module on the same side as the pump body 54 interface is marked as the first detection point, the pressure sensing module on the same side as the liquid outlet 712 is marked as the second detection point, the pressure sensing module opposite the second detection point is marked as the third detection point, and the pressure sensing module on the same side as the gas outlet 713 is marked as the fourth detection point. The pressure signals detected at each detection point are designated as P1, P2, P3, and P4, corresponding to the first detection point, second detection point, third detection point, and fourth detection point, respectively.

[0050] When the sodium acetate material is completely dried, the heat emitted from its interior has a lower moisture content. During the circulation process of being transported to compartment 71 and sent back, the amount of water precipitated by cooling is small, so that when the airflow enters compartment 71, most of it exists in the form of gas. Therefore, the pressure signal P1 detected by the first detection point is infinitely close to 0. At this time, only the second detection point can detect the interval force signal P2 caused by the condensed water in the annular pipeline 76. The conveying speed of the spiral conveying mechanism 1 is normal, and the transportation speed can be slightly increased according to production requirements. At the same time, the internal temperature and humidity are in good condition, and the quality of sodium acetate is guaranteed.

[0051] When the sodium acetate material is not completely dried or the hot air moisture content is high, the hot air is transported to the compartment 71 because of the cooling of the separated water, so that the first detection point can detect an obvious pressure signal P1. Based on this boundary, if the amount of water separated out is less, only the first detection point can detect an identifiable pressure signal P1, P3 and P4 are infinitely close to 0, and P2 is only detected as an annular pipeline 76 and does not participate in the evaluation criteria, indicating that the sodium acetate is mixed with some water vapor, but the water vapor content is less, and the conveying and turning process of the screw conveying mechanism 1 can be transferred to the outside. At this time, the conveying speed of the screw conveying mechanism 1 is not adjusted. If the amount of water separated out is more, the liquid extracted by the pump body 1 54 interface can be sprayed to the position of the third detection point. At this time, an obvious P3 signal can be detected, indicating that the sodium acetate is mixed with water vapor more. At this time, it is necessary to reduce the conveying speed of the screw conveying mechanism 1 so that the internal heat is fully radiated. If the amount of precipitated water is too much, the liquid extracted by the pump body 54 will impact the location of the fourth detection point due to the increase in flow rate. At this time, an obvious P4 signal can be detected, indicating that the sodium acetate is not dried sufficiently and there is too much water vapor inside. At this time, it is necessary to consider secondary drying of the sodium acetate material.

[0052] Furthermore, the cooling liquid temporarily stored in compartment 71 can serve as a heat exchange medium for the gas. When the liquid enters diverter box 7 through cooling channel 75, the temperature inside diverter box 7 drops due to the liquid temperature. At this point, the gas passing through annular pipe 76 is affected by the heat exchange effect within diverter box 7, further lowering the gas temperature. If the temperature inside diverter box 7 cannot meet the heat exchange requirements, three-way valve 8 opens the interface corresponding to the interior of diverter box 7 and closes the interface corresponding to clamp plate 52. Pump 1 54 then draws liquid from diverter box 7 into compartment 71, accelerating the liquid cooling process.

[0053] On the other hand, in the normal mode process of the regulating mechanism 2, a fixed cycle can be set to control the splint 52 to move and squeeze the sponge 51 to ensure that the sponge 51 has a good absorption effect.
