Description

Technical Field

[0001] The present invention relates to the technical field of acidic particle Yuanqing preparation, and specifically to a drying device and process for acidic particle Yuanqing preparation. Background Art

[0002] When preparing acidic particle Yuanqing, the raw materials are first prepared for condensation reaction to generate intermediate products, and then the intermediate products are subjected to sulfonation reaction and neutralization reaction in sequence to obtain a reaction liquid. The reaction liquid is filtered and washed to obtain a relatively pure acidic particle Yuanqing solution. The acidic particle Yuanqing solution is dried to finally obtain acidic particle Yuanqing.

[0003] There are many drying methods for drying acidic particle Yuanqing solution, among which spray drying is one of them. Spray drying is a process of dispersing liquid material into fine droplets through an atomizer, and then contacting with hot air to evaporate the water in an instant, thereby drying the material into a powder or granular product.

[0004] When preparing acidic particles of Yuanqing by spray drying, since the spray falls directly downward after entering the drying tower, in order to ensure that the spray can be dried as much as possible inside the drying tower, it is necessary to transport hot air with a higher temperature and a sufficient amount inside the drying tower to ensure that the spray enters the drying tower and is quickly dried into particles. This will result in a part of the hot air not being fully utilized, and the hot air will be transported to the drying tower in the process of being transported to the inside of the drying tower. The conveying pipeline is exposed to the air and will also cause heat loss, resulting in energy waste; the spray falls directly downward after entering the drying tower, and the spray does not stay in the drying tower for enough time, which will also result in incomplete drying of the spray, resulting in the formed particles being not dry enough, and secondary drying is required, affecting the preparation efficiency of acidic particles of Yuanqing.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0038] like Figure 1 and Figure 2 As shown, a drying device for preparing acidic particle Yuanqing includes a mounting frame 6, a drying tower 1 is fixedly mounted on the inner side of the mounting frame 6, an atomizer 2 is arranged at the top of the drying tower 1, a hot air inlet 3 is arranged at the top of the drying tower 1 and outside the atomizer 2, discharge ports are arranged at the bottom and side of the drying tower 1, the side discharge port is connected to an external cyclone separator, a spoiler mechanism 4 is arranged inside the drying tower 1, and an auxiliary mechanism 5 for preheating the solution is arranged at the top of the drying tower 1.

[0039] like Figure 1 and Figure 3As shown, the auxiliary mechanism 5 includes a fixed shell 51 fixedly connected to the top of the drying tower 1, a solution containing chamber 53 is fixedly connected inside the fixed shell 51, a hot air circulation chamber 52 is formed between the solution containing chamber 53 and the inner wall of the fixed shell 51, the left side of the fixed shell 51 is fixedly and penetrated with the hot air inlet 3, the right side of the fixed shell 51 is fixedly and penetrated with a hot air distributor 55, the end of the hot air distributor 55 away from the fixed shell 51 is fixedly and penetrated with the upper surface of the drying tower 1, a reserved box 54 is arranged below the fixed shell 51, and the bottom end of the reserved box 54 is fixedly and penetrated with the atomizer 2.

[0040] like Figure 1 and Figure 3 As shown, an inverted V-shaped partition plate is provided on the inner wall of the bottom end of the solution holding chamber 53, and a solution feeding pipe is provided on the upper surface of the solution holding chamber 53. The top end of the solution feeding pipe passes through the outer surface of the fixed shell 51. The bottom end of the solution holding chamber 53 and the upper surface of the reserved box 54 are connected through a connecting pipe. An electronic valve is provided on the connecting pipe. The electronic valve controls the connection and disconnection between the solution holding chamber 53 and the reserved box 54.

[0041] During specific use, first, the hot air inlet 3 generates hot air and transports it to the inside of the hot air circulation chamber 52, and then the hot air enters into the drying tower 1 through the hot air circulation chamber 52 and the hot air distributor 55. At the same time, the external feeding mechanism transports the acidic particle Yuanqing solution to the inside of the solution holding chamber 53. After the solution enters into the solution holding chamber 53, the hot air preheats the solution inside the solution holding chamber 53 during the process of passing through the hot air circulation chamber 52. The preheated solution enters into the reserved box 54. The solution in the reserved box 54 is transported to the atomizer 2. The atomizer 2 disperses the solution into fine droplets. These droplets have a large specific surface area. After contacting with the hot air, the moisture evaporates rapidly. Under the action of the hot air, the temperature of the droplets gradually increases, and the moisture is continuously evaporated, eventually forming dry particles or powder.

[0042] The connection between the solution holding chamber 53 and the reserved box 54 is controlled by an electronic valve between the solution holding chamber 53 and the reserved box 54. When the reserved box 54 is filled with solution, the electronic valve is closed. When the solution in the reserved box 54 is about to be used up, the electronic valve is opened again to fill the reserved box 54 with the preheated solution again. By controlling the connection between the reserved box 54 and the solution holding chamber 53, the solution in the solution holding chamber 53 can have more preheating time to ensure that each time the solution entering the reserved box 54 can maintain a higher temperature, the subsequent solution after atomization The efficiency of drying the spray is higher, and at the same time, it can also prevent the temperature of the preheated solution in the reserved box 54 from being affected by the newly replenished solution in the solution holding chamber 53.

[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the spoiler mechanism 4 includes two vertically symmetrical supporting cross bars 41 fixedly connected to the inner wall of the drying tower 1, and a fixed column 42 coaxial with the drying tower 1 is fixedly connected to the two supporting cross bars 41. Three spoilers 45 evenly distributed vertically are arranged on the fixed column 42, and a first adjusting member 43 is arranged on the fixed column 42 and the spoiler 45, and a second adjusting member 44 is arranged on the first adjusting member 43, the fixed column 42 and the supporting cross bar 41.

[0044] During specific use, before drying the solution, the spacing of the spoiler 45 is adjusted through the first adjusting member 43 according to the spray amount, so as to adjust the spoiler 45's coverage area for blocking the mist droplets, and then the inclination angle of the spoiler 45 is adjusted through the second adjusting member 44, so as to adjust the degree of resistance of the spoiler 45 to the mist droplets.

[0045] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the spoiler 45 includes a plurality of circumferentially distributed hinged seats 455 fixedly connected to the fixed column 42, a mounting seat 454 is hinged on the hinged seat 455, a plurality of barrier blades 451 evenly distributed from top to bottom are hinged on the mounting seat 454, and a limiting slide groove 453 is provided on the lower surface of the barrier blade 451, and a linkage column 452 is fixedly connected to the upper surface of the barrier blade 451, and the linkage column 452 and the limiting slide groove 453 on two adjacent barrier blades 451 are slidably matched.

[0046] like Figure 4 , Figure 8 and Fig. 9 As shown, the first adjusting member 43 includes a mounting plate 432 fixedly connected to the outer circumferential surface of the fixing column 42, the mounting position of the mounting plate 432 corresponds to the spoiler 45, a plurality of telescopic connecting rods 433 are embedded and connected to the outer circumferential surface of the mounting plate 432, an L-shaped connecting rod 434 is ball-hinged on the lower surface of the telescopic end of the telescopic connecting rod 433, the horizontal section of the L-shaped connecting rod 434 is fixedly connected to the lower surface of the blocking blade 451 at the bottom end thereof corresponding to it, and a transmission shaft 431 is rotatably connected on the outer circumferential surface of the fixing column 42 and below the mounting plate 432.

[0047] like Figure 4 , Figure 8 and Fig. 9As shown, the upper and lower surfaces of the mounting plate 432 are both provided with inner gear rings, the transmission shaft 431 is meshed with the inner gear rings on the corresponding mounting plate 432 through gears, the upper surface of the supporting cross bar 41 at the bottom end is fixedly installed with a driving motor through a motor seat, a toothed disc is fixedly connected to the output shaft of the driving motor, the toothed disc is meshed with the bottom end of the bottom transmission shaft 431 through gears, the vertical section of the L-shaped connecting rod 434 is telescopically arranged, and the vertical section and the horizontal section of the L-shaped connecting rod 434 are hinged.

[0048] In specific use, when the separation distance of the spoiler 45 is adjusted by the first adjusting member 43, the driving motor first drives the mounting plate 432 to rotate on the fixing column 42 through the transmission shaft 431, and the mounting plate 432 drives the plurality of barrier blades 451 to rotate from bottom to top in sequence through the telescopic connecting rod 433 and the L-shaped connecting rod 434. Specifically, when the linkage column 452 of the first barrier blade 451 slides to the inner edge of the limiting slide groove 453 on the lower surface of the second barrier blade 451, the second barrier blade 451 starts to rotate along with the first barrier blade 451. When the second barrier blade 451 starts to rotate, the linkage column 452 thereon slides inside the limiting slide groove 453 on the lower surface of the third barrier blade 451. When the linkage column 452 on the second barrier blade 451 slides to the edge of the limiting slide groove 453 on the lower surface of the third barrier blade 451, the third barrier blade 451 starts to rotate along with the second barrier blade 451, and so on. As the barrier blade 451 continues to rotate, multiple barrier blades 451 are driven to unfold in sequence from bottom to top to form a fan-shaped spoiler area with the mounting seat 454.

[0049] It should be noted that the fan-shaped spoiler areas formed when the three spoilers 45 are opened are staggered. In addition, the lengths of the barrier blades 451 in the three spoilers 45 can be set to gradually increase from top to bottom, which not only ensures that the hot air and spray can flow downward smoothly, but also has a certain barrier effect on the spray, thereby prolonging the drying time of the spray in the hot air.

[0051] During specific use, when the inclination angle of the spoiler 45 is adjusted by the second adjusting member 44, the electric telescopic rod 441 is contracted to drive the connecting slide 442 to move downward on the supporting cross bar 41, and the connecting slide 442 pulls the mounting seat 454 to rotate on the hinge seat 455 through the linkage rod 443, so as to adjust the inclination angle of the barrier blade 451, so as to facilitate the dry particles to slide down and be discharged under their own weight and hot air, and also change the area of ​​the spoiler 45 projected on the horizontal plane, that is, change the spoiler range, and at the same time, through the telescopic connection rod 433 The telescopic connection rod 433 is retracted and hinged with the L-shaped connection rod 434, when adjusting the inclination angle of the barrier blade 451, the telescopic connection rod 433 and the L-shaped connection rod 434 will not affect the normal adjustment of the inclination angle of the barrier blade 451. The vertical section of the L-shaped connection rod 434 is retractable and hinged with its horizontal section, so that the inclination angle of the barrier blade 451 can be adjusted more flexibly.

[0052] like Figure 1 and Figure 2 As shown, the use process of using the above-mentioned drying equipment to dry and prepare acidic particle Yuanqing includes the following steps: S1. First, the hot air inlet 3 generates hot air and continuously transports it to the interior of the drying tower 1.

[0054] S3. The acidic particle Yuanqing solution is transported to the interior of the atomizer 2 through the auxiliary mechanism 5, and the atomizer 2 disperses the solution into droplets with extremely small diameters and sprays them inside the drying tower 1.

[0055] S4. When the mist droplets are scattered inside the drying tower 1 and continue to fall downward, when passing through the spoiler mechanism 4, the spoiler mechanism 4 blocks the falling mist droplets, so that the mist droplets can stay inside the drying tower 1 for a longer time and fully contact with the hot air. The coverage area of ​​the spoiler 45 is adjusted by the first adjusting member 43, and the inclination angle of the spoiler 45 is adjusted by the second adjusting member 44, so as to change the spoiler range.

[0057] S6. The external cyclone separator sucks out a part of the particles through the side discharge port, and collects them together after being separated from the hot air.
