Description

Technical Field

[0001] This utility model relates to the technical field of centrifugal drying, and in particular to a centrifugal drying device for the production of vanillin butyl ether. Background Technology

[0002] Vanillyl butyl ether has wide applications in food, cosmetics, and other fields. Currently, the main synthesis method of vanillyl butyl ether is obtained by dehydration condensation of vanillyl and n-butanol under an acidic catalyst. However, the yield of this method is very low, mainly because the water produced in the reaction hydrolyzes the commonly used acidic catalyst and loses its catalytic effect, thereby inhibiting the etherification reaction. Later, it was reported that solid acid catalysts obtained by immobilizing some acidic catalysts on molecular materials can improve the yield of this system. However, such catalysts are not easy to obtain, are difficult to prepare, and are costly, making them difficult to apply to large-scale production. Moreover, using vanillyl as a raw material leads to high costs. Using water as a solvent overcomes the disadvantages of using ethanol as a solvent in traditional processes, reduces the subsequent product desolvation process, avoids ethanol consumption, saves costs, and the crude product obtained from the reaction can be directly centrifuged and dried.

[0003] The existing Chinese utility model patent with application number CN201520317103.0 relates to a centrifugal drying barrel, including a cylinder, an opening, a through hole, a main shaft, a spiral guide plate, a connecting rod, a support rod, and a protruding column, which can make the centrifugal process of the drying barrel stable and the product drying effect good.

[0004] However, in actual use, the above-mentioned device makes it difficult to remove the dried product. The solid particles need to be removed by tilting the entire device, which increases the labor intensity of the operators. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a centrifugal drying device for the production of vanillin butyl ether. The device is driven to rotate by a centrifugal device, and the dried material is supported by a carrying device, which makes it easy for operators to remove the material. A protective device monitors the rotation process of the centrifugal device to prevent damage to the equipment itself during centrifugation, thereby improving the practicality of the device.

[0006] This utility model discloses a centrifugal drying device for the production of vanillin butyl ether; it includes a centrifugal device, a support device, and a protective device. The support device is installed on the centrifugal device, and the protective device is installed on the centrifugal device. The centrifugal device is driven to rotate, and the support device carries the dried material, making it easy for operators to remove the material. The protective device monitors the rotation process of the centrifugal device to prevent damage to the equipment itself during centrifugation, thus improving the practicality of the device.

[0007] Preferably, the centrifugal device includes a drying drum, a reducer, a motor, a support plate, a ring frame, and a protective net. A reducer is installed on the lower end face of the drying drum, and a motor is mounted on the reducer. The output end of the reducer extends through the upper end face of the drying drum into the interior of the drying drum and connects to the support plate. A funnel-shaped groove is provided on the upper end face of the support plate, and a ring frame is provided along the edge of the upper end face of the support plate. Multiple sets of protective nets are installed on the ring frame. The ring frame and protective nets work together to intercept the material, facilitating the removal of residual liquid from the material and improving the efficiency of drying the material. Turning on the motor transmits power through the reducer to the support plate, driving the support plate to rotate and completing the centrifugal drying process, thus improving the practicality of the device.

[0008] Preferably, it also includes multiple sets of support columns. Multiple sets of support columns are evenly arranged at the lower part of the ring frame to fix the lower part of the protective net. The multiple sets of support columns at the lower part of the ring frame provide auxiliary support for the protective net, reducing the situation where the protective net is subjected to excessive pressure during centrifugation due to too much material, thus improving the protective performance and practicality of the device.

[0009] Preferably, the supporting device includes a pick-and-place plate, a magnet, a pick-and-place rack, a drainage trough, and a sealing strip. The pick-and-place plate is placed on the upper surface of the supporting plate, and a magnet is installed on the bottom surface of the pick-and-place plate. The pick-and-place rack is provided at the bottom of the upper surface of the pick-and-place plate, and a drainage trough is provided at the bottom of the upper surface of the supporting plate, which is connected to the lower surface of the supporting plate. A groove is provided along the edge of the upper surface of the supporting plate, and a sealing strip is provided on the lower surface of the pick-and-place plate corresponding to the groove on the supporting plate. The sealing strip cooperates with the groove on the supporting plate to reduce the liquid entering the space between the supporting plate and the pick-and-place plate. The pick-and-place plate supports the solid vanillin butyl ether. The magnet makes the pick-and-place plate adsorb and connect with the supporting plate, preventing the pick-and-place plate from detaching from the supporting plate and flying out during the rotation of the supporting plate. The pick-and-place rack makes it easy for the operator to remove the pick-and-place plate as a whole, improving the practicality of the device.

[0010] Preferably, the device also includes a steel pipe, a nozzle, and fastening bolts. A sealing cover is provided on the upper end face of the drying barrel, and a sleeve is provided on the upper end face of the sealing cover. The steel pipe enters from the upper end face of the sealing cover through the sleeve to the lower side of the sealing cover. A nozzle is connected to the lower end face of the steel pipe, and fastening bolts are installed on the sleeve. High-temperature steam for drying is sent into the drying barrel through the steel pipe and the nozzle to assist in drying the material, thereby improving the drying efficiency of the equipment. The height of the steel pipe extending into the drying barrel can be changed according to production needs, thereby changing the contact distance between the nozzle and the material. The height of the steel pipe is fixed by rotating the fastening bolts, which improves the practicality of the device.

[0011] Preferably, the protective device includes a pressure switch, a spring, a C-shaped frame, rollers, anti-collision strips, and limiting rods. Anti-collision strips are provided on the outer edge of the ring frame. Multiple sets of circular grooves are evenly distributed on the inner side of the drying drum, with the height of the grooves matching the height of the anti-collision strips. A pressure switch is installed on the inner plane of each circular groove, connected to the outer side of the C-shaped frame via a spring. Rollers are installed on the C-shaped frame. A set of limiting rods is provided at the top and bottom of the outer side of the C-shaped frame. Limiting grooves are provided on the inner side of the drying drum at the height of each limiting rod on the C-shaped frame, with the limiting rods extending into these grooves. When there is too much material in the centrifuge or a malfunction occurs, the bearing plate and ring frame shake as a whole. The limiting rods push the rollers, transmitting power to the pressure switch via the spring. When the pressure switch detects a pressure exceeding a preset value, it controls the equipment to stop operating, preventing further damage or malfunction. The limiting rods limit the lateral movement of the C-shaped frame, improving the device's protective and safety features.

[0012] Preferably, the device also includes a filter chamber and a filter screen. A drain hole is provided on the bottom surface of the drying barrel, and a filter chamber is installed on the drain hole. A filter screen is installed inside the filter chamber. The filter screen in the filter chamber filters and intercepts solid materials in the discharged liquid and gas, reducing material waste and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the centrifugal device drives the rotation, and the carrying device carries the dried material, making it easy for operators to take out the material. The protective device monitors the rotation process of the centrifugal device to prevent damage to the equipment itself during centrifugation, thus improving the practicality of the device.
