Description

Technical Field

[0001] The present invention relates to the technical field of sodium acetate production, and specifically to a temperature-controlled dust-free conveying device for sodium acetate. Background Art

[0002] Sodium acetate, also known as sodium acetate, is a common organic compound, usually existing in the form of sodium acetate trihydrate, being colorless transparent crystals or white granules, soluble in water and slightly soluble in ethanol. Anhydrous sodium acetate is colorless transparent crystals with a melting point of 324 °C. Sodium acetate has hygroscopicity and is prone to deliquescence in the air.

[0003] The production of sodium acetate mainly involves three parts: reaction, crystallization, and drying. The drying temperature of sodium acetate should not be too high, generally controlled at about 120 °C. Too high a temperature may cause the decomposition of sodium acetate, affecting the product quality. After drying, solid sodium acetate will be transported using a closed conveyor belt or screw conveyor to avoid dust flying.

[0004] During the conveying process, attention should be paid to the sealing of the conveying device and the temperature control during transportation. For a conveying device with sealing, during the conveying process, sodium acetate will be turned and scattered, causing the heat contained in it to be dissipated. The heat accumulates in the closed device and cannot be evacuated in time, resulting in too high a local temperature in the device, thereby affecting the quality of sodium acetate.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 11 , the present invention provides a technical solution: a temperature-controlled dust-free conveying device for sodium acetate, which includes a screw conveying mechanism 1 and a regulation mechanism 2. The screw conveying mechanism 1 includes a cover plate 3, and a number of heat dissipation windows 31 are spaced apart on the cover plate 3. A dredging plate 4 is installed on the heat dissipation windows 31, and several mesh holes 41 are opened on the dredging plate 4. The regulation mechanism 2 includes a number of collection boxes 5 corresponding to the heat dissipation windows 31.

[0022] As Figure 4 , Figure 5 shown, a sponge body 51 is arranged in the collection box 5. A clamping plate 52 is arranged on one side in the collection box 5. The clamping plate 52 is arranged in a Z-shaped structure. A hollow cavity 521 is arranged inside the clamping plate 52, and several suction ports 522 are opened on the side facing the sponge body 51. A partition plate 53 is arranged in the hollow cavity 521. The side of the partition plate 53 facing the suction ports 522 is an output area 531, and the side of the partition plate 53 facing away from the suction ports 522 is an input area 532. A pump body one 54 and a pump body two 55 are respectively connected to the output area 531 and the input area 532.

[0023] The supplementary description based on the above structure is as follows: Preferably, a filter membrane is arranged on the mesh holes 41 to prevent the sodium acetate conveyed inside the screw conveying mechanism 1 from overflowing. The screw conveying mechanism 1 is used to convey solid sodium acetate. During the conveying process of sodium acetate, it will be continuously turned and dispersed, and the heat contained inside will rise upward. The hot gas penetrates through the dredging plate 4 and seeps into the collection box 5. During this process, the water vapor and the condensed liquid are absorbed by the sponge body 51. The pump body one 54 extracts the gas-liquid mixture from the sponge body 51 through the suction ports 522, and the gas-liquid mixture passes through the output area 531. The pump body two 55 conveys gas to the sponge body 51 through the suction ports 522 to balance the internal pressure. The collection box 5 thus realizes absorbing the excess heat accumulated by the screw conveying mechanism 1. At the same time, after condensing and collecting the water vapor in the heat, the dried gas with reduced temperature is sent back again, improving the conveying quality of sodium acetate without damaging the internal pressure.

[0024] Furthermore, as Figure 6As shown in the figure, a tooth groove 523 is provided on the upper surface of the clamping plate 52. A rack 61 is provided in cooperation with the tooth groove 523. The rack 61 is slidably fitted with a fixing plate 62. Brackets 63 are connected to both sides of the fixing plate 62. The brackets 63 are fixedly connected to the cover plate 3. A screw rod 64 passes through the middle of the rack 61 and is in threaded cooperation with it. One end of the screw rod 64 is connected to a first motor 65, and the first motor 65 is fixed on the cover plate 3.

[0025] In actual operation, clamping grooves are provided on both sides of the rack 61, and clamping blocks are provided on the fixing plate 62 in cooperation with the clamping grooves. When the first motor 65 controls the screw rod 64 to rotate, the rack 61 will move forward or backward along the direction of the screw rod 64. When the rack 61 moves, the tooth groove 523 cooperating with the rack 61 will drive the clamping plate 52 to move accordingly, so as to adjust the position of the clamping plate 52 in the collection box 5. The clamping plate 52 approaches and squeezes the sponge body 51, making the water absorbed inside easier to drain.

[0026] In one embodiment, as Figure 7 shown, a flow distribution box 7 is provided on the fixing plate 62. The flow distribution box 7 corresponds to each collection box 5, and one ends of a first pump body 54 and a second pump body 55 are respectively connected to the flow distribution box 7.

[0027] As Figure 8 、 Figure 9 shown, a compartment 71 is provided at the interface position of the flow distribution box 7 relative to the first pump body 54. A sliding groove 711 is provided on the upper side of the compartment 71. A frame 72 is fixed at the bottom of the sliding groove 711. The middle of the frame 72 is open. A spring 73 is connected to the frame 72 corresponding to the position where the sliding groove 711 is located. A pressure sensing module is provided at the connection position of the frame 72 and the spring 73. The other end of the spring 73 is connected to a grille plate 74, and several grille holes 741 are provided on the grille plate 74.

[0028] Furthermore, as Figure 10 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 a cooling channel 75. The cooling channel 75 is in a ring structure and the outlet end communicates with the inside of the flow distribution box 7. A liquid level detection module and a temperature detection module are provided inside the flow distribution box 7.

[0029] Even further, as Figure 7 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 upper surface of the grille 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 second pump body 55.

[0030] A three-way valve 8 is provided on the connection route between the first pump body 54 and the output area 531, and the other interface of the three-way valve 8 is connected to the inside of the flow distribution box 7.

[0031] It should be noted that: The gas flow path is set to start from the collection box 5, pass through the output area 531 to reach the compartment 71, separate from the liquid transported together, and is pumped to the input area 532 by the second pump 55 through the annular pipeline 76, and finally returned to the collection box 5. The liquid flow path is set to start from the collection box 5, pass through the output area 531 to reach the compartment 71, be temporarily stored in the compartment 71 after separating from the gas. When the liquid in the compartment 71 reaches a certain height, the liquid enters the cooling channel 75 and finally flows to the shunt box 7. The three-way valve 8 is used to control the opening and closing states of the three interfaces, thereby changing the input source of the first pump 54.

[0032] As Figure 11 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.

[0033] A rotating shaft 14 is rotatably arranged inside the housing 11. A spiral blade 15 is fixed on the surface of the rotating shaft 14. One end of the rotating shaft 14 extends out of the surface of the housing 11 and is connected to the second motor 16.

[0034] In actual operation, sodium acetate enters the inside of the housing 11 from the material inlet 12. The second motor 16 controls the rotation of the rotating shaft 14, so that the spiral blade 15 rotates, driving the sodium acetate to move towards the material outlet 13 and being sent out from the material outlet 13.

[0035] The specific implementation method is as follows: The transportation process of sodium acetate is as follows: After production, sodium acetate enters the spiral conveying mechanism 1 through the conveying pipeline. The spiral 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 spiral conveying mechanism 1. Then, sodium acetate is output from the outlet of the spiral conveying mechanism 1.

[0036] The normal mode process of the regulating mechanism 2 is as follows: When sodium acetate is normally conveyed inside the spiral conveying mechanism 1, the internal hot air rises into the collection box 5. The sponge body 51 captures and absorbs this hot air, and the first pump 54 is started. Under normal conditions, the clamping plate 52 closely adheres to one inner wall of the collection box 5, and the sponge body 51 fits the suction port 522 of the clamping plate 52. Under the pumping state of the first pump 54, the hot air absorbed in the sponge body 51 is transferred to the output area 531, and then transferred to the compartment 71. During this process, the temperature of the hot air flow drops. The air flow entering the compartment 71 passes through the annular pipeline 76, causing the temperature to further decrease. The annular pipeline 76 is inclined towards the gas outlet 713. During the cooling process of the air flow, if condensate is generated, the liquid will flow back to the compartment 71 along the inclined direction; the gas part continues to move forward along the pipeline and is finally pumped back to the collection box 5 by the second pump 55. The temperature of the returned air flow decreases, which can effectively reduce the temperature inside the spiral conveying mechanism 1 and avoid excessive local heat, preventing the decomposition of sodium acetate.

[0037] On the basis of the above process, mark the positions of the pressure sensing modules. Mark the pressure sensing module on the same side as the interface of the first pump body 54 as the first detection point, the pressure sensing module on the same side as the liquid outlet 712 as the second detection point, the pressure sensing module opposite to the second detection point as the third detection point, and the pressure sensing module on the same side as the gas outlet 713 as the fourth detection point. The pressure signals detected by each detection point are set as P1, P2, P3, and P4, corresponding to the first detection point, the second detection point, the third detection point, and the fourth detection point respectively.

[0038] When the sodium acetate material is completely dried, the hot air emitted from its interior has a reduced moisture content. During the process of being transported to the compartment 71 and returned in the circulation, less water is cooled and precipitated, so that when the air flow enters the 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 force signal P2 caused by the condensed water in the annular pipeline 76. The conveying speed of the screw conveying mechanism 1 is normal, and the conveying 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.

[0039] When the sodium acetate material is not completely dried or the moisture content of the hot air mixed in the material is high, more water is cooled and precipitated during the process of transporting the hot air to the compartment 71, so that the first detection point can detect an obvious pressure signal P1. Taking this as the boundary for division, if the amount of precipitated water is small, only the first detection point can detect the recognizable pressure signal P1, P3 and P4 are infinitely close to 0, and P2 is only used for the detection of the annular pipeline 76 and does not participate in the evaluation standard, indicating that there is some water vapor in the sodium acetate, but the water vapor content is small and can be transferred to the outside through the conveying and turning process of the screw conveying mechanism 1. At this time, the conveying speed of the screw conveying mechanism 1 is not adjusted. If the amount of precipitated water is large, the liquid pumped out from the interface of the first pump body 54 can be sprayed to the position where the third detection point is located, and at this time, an obvious P3 signal can be detected, indicating that there is more water vapor mixed in the sodium acetate. At this time, the conveying speed of the screw conveying mechanism 1 needs to be reduced to allow the internal hot air to fully dissipate. If the amount of precipitated water is too large, the liquid pumped by the first pump body 54 will impact to the position where the fourth detection point is located due to the increased flow rate, and at this time, an obvious P4 signal can be detected, indicating that the sodium acetate is not sufficiently dried and there is too much water vapor mixed inside. At this time, it is necessary to consider subjecting the sodium acetate material to secondary drying treatment.

[0040] Furthermore, the cooling liquid temporarily stored in the compartment 71 can be used as the heat exchange medium for the gas. When the liquid enters the distribution box 7 through the cooling channel 75, the internal temperature of the distribution box 7 decreases due to the influence of the liquid temperature. At this time, the gas passing through the annular pipeline 76 will be affected by the heat exchange effect in the distribution box 7, further reducing the gas temperature. If the temperature in the distribution box 7 cannot meet the heat exchange requirements, the three-way valve 8 opens the interface corresponding to the inside of the distribution box 7 and closes the interface corresponding to the clamping plate 52, and the first pump body 54 pumps the liquid from the distribution box 7 into the compartment 71 to accelerate the liquid cooling process.

[0041] On the other hand, in the conventional mode process of the regulation mechanism 2, a fixed cycle can be set to control the clamping plate 52 to move towards the sponge body 51 and squeeze it to ensure good absorption effect of the sponge body 51.
