Description

Technical Field

[0001] The present invention relates to the field of drying, and specifically to a drying device and drying process for sulfonamide processing. Background Art

[0002] In the production process of sulfonamide raw materials and their intermediates, the drying process is a key link to ensure the product stability and meet the moisture content standard. The conventional sulfonamide processing flow usually includes the following steps: Wet materials first enter the drying equipment, dehydrate under the action of the drying equipment, and the materials after thermal drying are cooled to near room temperature to avoid moisture absorption and caking caused by direct exposure to air at high temperature. Then the materials enter the next process.

[0003] However, traditional sulfonamide drying equipment has significant defects. If the sulfonamide materials after high-temperature drying enter the subsequent process without sufficient cooling, the temperature difference between their surface temperature and the environment will cause water vapor condensation, resulting in moisture absorption and rehumidification of the materials, seriously affecting the product quality stability. Current solutions mostly add independent cooling equipment after the drying section, such as spiral coolers, fluidized bed coolers, etc., but this will occupy additional production line space, leading to increased equipment investment and operation and maintenance costs; at the same time, traditional sulfonamide drying equipment reduces the probability of internal material caking through vibration, but when adjusting the frequency, only the overall vibration frequency of the equipment can be adjusted, resulting in the positions that do not need to be adjusted being affected, instead exacerbating the uneven distribution of materials and causing a decrease in drying efficiency.

[0021] When it is necessary to dry the material, first start the heating plate 501 to make the drying area 102 in a high-temperature state. Then put the material into the feeding port 104, and then start the driving motor 201. The driving motor 201 drives the connected sprocket 202 to rotate. The sprocket 202 drives other sprockets 202 to rotate through the chain 203. Several sprockets 202 will drive the connected driving bevel gears 204 to rotate.

When the frequency of the vibrating plate 106 needs to be adjusted in the reverse direction, rotate the limit block 404. The limit block 404 is disengaged from the limit of the adjusting rod 401.

[0023] To achieve the effect of discharging the water vapor in the drying area 102, a moisture absorption box 503 is provided. The moisture absorption box 503 is fixedly connected in the transmission area 103. Two moisture absorption pipes 504 are fixedly communicated with the moisture absorption box 503. One moisture absorption pipe 504 is fixedly communicated with the upper end of the drying area 102, and the other moisture absorption pipe 504 is fixedly communicated with the lower end of the drying area 102.

[0024] In the moisture absorption box 503, there is provided a device capable of absorbing water vapor, such as a gas drying pipe. At the same time, a ventilation device, such as an air pump, is also provided in the moisture absorption box 503. Thus, the device carrying water vapor at the upper end of the drying area 102 is sucked into the moisture absorption box 503 through the moisture absorption pipe 504, and then becomes dry gas and is discharged into the drying area 102 from the lower end of the drying area 102 through the moisture absorption pipe 504. After the above process, the material is stored in the storage area 109.

[0025] To solve the problem of the cooling equipment additionally occupying the production line space and achieve the effect of recycling the materials into the drying equipment for cooling and reducing the occupied production line space, a material cooling component is provided. The material cooling component includes an inflatable box 505 and a material suction box 508. The inflatable box 505 is fixedly connected in the transmission area 103. Two air charging pipes 506 are fixedly communicated with the moisture absorption box 503. One air charging pipe 506 is fixedly communicated with the upper end of the drying area 102, and the other air charging pipe 506 is fixedly communicated with the lower end of the drying area 102. The storage area 109 is arranged below the drying area 102 and the two are communicated with each other. The discharge port 105 is fixedly communicated with one side of the storage area 109. The bottom surface of the storage area 109 is inclined, being lower at the position close to the discharge port 105. The upper end of the housing 101 is fixedly connected with the material suction box 508. Two material suction pipes 507 are fixedly communicated with both sides of the material suction box 508. One material suction pipe 507 is fixedly communicated with the feed inlet 104, and the other material suction pipe 507 is fixedly communicated with the lower part of the storage area 109.

[0026] The inflatable box 505 stores a low-temperature gas that does not react with the material, such as nitrogen. The material suction box 508 is provided with equipment that can transfer high-temperature materials, such as a powder conveying pump. The storage area 109 is provided with door opening and closing equipment, such as electric doors, at the positions of the material suction pipe 507 and the discharge port 105. When it is necessary to cool the high-temperature material, first, the electric door at the position of the discharge port 105 is opened. Then, the material suction box 508 sucks the high-temperature material in the storage area 109 from the material suction pipe 507, and then discharges the high-temperature material into the feed port 104 through another material suction pipe 507. At the same time, the inflatable box 505 starts to fill the drying area 102 with cold air from the air filling pipe 506 at the lower end of the drying area 102. The cold air forms a cycle in the drying area 102, and the material re-enters the storage area 109 after passing through the vibrating plate 106 from the feed port 104, and the material is cooled. At this time, the electric door at the position of the discharge port 105 is closed, and the electric door at the position of the discharge port 105 is opened, and the cooled material is discharged from the discharge port 105. When cooling, since there is no caking phenomenon in the material now, the frequency of the vibrating plate 106 can be uniformly adjusted to an appropriate frequency. First, rotate the limit block 404 beside the adjustment handle 403, and open the limit blocks 404 on all the adjustment rods 401. The limit block 404 cancels the limit on the adjustment handle 403. Then, move the adjustment handle 403. The adjustment handle 403 drives the adjustment plate 402 to move. The distance that the adjustment plate 402 can move is greater than that of the adjustment rod 401. Therefore, the adjustment plate 402 drives several different adjustment rods 401 to move. Each adjustment rod 401 drives a spline shaft sleeve 302 to move, thereby changing the vibration frequency of the vibrating plate 106. If the frequency of a single vibrating plate 106 has been adjusted before, when the adjustment plate 402 moves, the adjustment plate 402 drives the unadjusted adjustment rods 401 to move, so that when the adjustment plate 402 is moved, the vibrating plates 106 with different frequencies can be adjusted to the same frequency. Then, rotate all the limit blocks 404 so that the limit blocks 404 re-limit the adjustment handle 403 and the adjustment rods 401.
