Description

Technical Field

[0001] The invention relates to the technical field of furan phenol etherification reaction, and in particular to a device and method for pretreating raw materials for furan phenol etherification reaction. Background Art

[0002] As an important chemical intermediate, furanol has broad application prospects in pesticide production and other fields. It is an odorless white crystalline solid, soluble in organic solvents such as dichloromethane, toluene, alcohol, ether, etc., insoluble in water, has specific chemical reactivity, and can be used to synthesize other compounds.

[0003] After searching, the Chinese patent with publication number CN114345058A discloses a gas-liquid separation treatment device and process for furanol etherification reaction, including a centrifugal separator, a refrigeration separator and a storage tank. A stirring motor is installed on the top of the centrifugal separator, and a stirring paddle is connected to the bottom of the stirring motor. A gas-liquid feed pipeline is connected to one side of the top of the centrifugal separator. Stirring baffles are installed on both sides of the inside of the centrifugal separator, and a collector is provided at the bottom of the stirring baffle. The gas-liquid separation treatment device stirs the gas-liquid mixture through the centrifugal separator. Under the action of centrifugal force, the droplets are thrown into the set collector to avoid the droplets from forming a thick film inside and affecting the overall heat exchange. A gas phase outlet baffle is provided at the gas phase outlet at the bottom of the centrifugal separator to avoid large droplets being directly brought into the refrigeration separator by the gas phase. The gas-liquid separation speed of the present invention is fast, the efficiency is high, and the separation is thorough, the condensation efficiency is high, and it is convenient to collect the liquid. However, when the scheme is actually used, there are still the following shortcomings: In the key pretreatment step before the furanol etherification reaction, it is crucial to efficiently dry the catechol and sodium carbonate in the raw materials. However, the currently widely used technical method for processing these two raw materials generally adopts the method of directly placing them in a vacuum drying tank for vacuum drying. Although this approach seems direct and easy to operate, the raw materials are prone to stacking inside the vacuum drying tank. This stacking not only limits the effective transfer of heat and steam, which greatly reduces the heat exchange efficiency during the drying process, but also may lead to uneven drying. The moisture and impurities in the raw materials in some areas cannot be fully removed, which seriously affects the overall drying efficiency of the material.

[0004] Therefore, the present application provides a device and method for pretreating raw materials for furanol etherification reaction to meet the requirements of rapid drying pretreatment of raw materials. Summary of the invention

[0016] Beneficial effects of the present invention: 1. The device and method for pretreating raw materials for furanol etherification reaction, by setting a driving structure and a knocking component, drive the connected telescopic rod to rotate through a servo motor, thereby driving the processing ring to oscillate in the vertical direction while rotating. During this process, the knocking component intermittently knocks the bottom surface of the processing ring to cause the processing ring to vibrate. This vibration can further spread the raw materials evenly on the processing ring, avoiding the accumulation and agglomeration of the raw materials during the drying process, thereby improving the drying efficiency and quality of the raw materials.

[0017] 2. The device and method for pretreating raw materials for furanol etherification reaction, by setting a processing ring and a material shifting assembly, during the rotation and oscillation of the processing ring, the shifting plate shifts the lifted raw materials through the transmission of components such as linkage gears and transmission shafts. This shifting action makes the raw materials more dispersed in the processing ring, and enhances the turning effect of the raw materials. The improvement of the turning effect helps the raw materials to be more fully exposed to the dry environment, thereby accelerating the drying speed and improving the drying efficiency.

[0018] 3. The device and method for pretreating raw materials for furanol etherification reaction, by setting a fixed plate and a discharge assembly, after drying is completed, the electric push rod drives the positioning rod to slide along the positioning groove and the arc groove, thereby driving the sealing baffle to rotate, so that it is separated from the fixed plate and the processing ring. At this time, the raw materials in the processing ring slide down under the action of gravity and are discharged through the discharge pipe. The opening and closing process of the sealing baffle realizes rapid unloading. At the same time, the sealing baffle can also shield components such as servo motors when opened, avoiding their obstruction to the discharge of raw materials, thereby ensuring smooth and efficient unloading.

[0024] like Figures 1 to 9As shown, a raw material pretreatment device for furan phenol etherification reaction comprises a temperature control treatment tank 1 and a vacuum treatment box 2, wherein the vacuum treatment box 2 is arranged on the outer wall of the temperature control treatment tank 1, and further comprises: a fixed sleeve 3, which is fixedly installed inside the temperature control treatment tank 1 through a connecting frame; a guide ring 4, which is fixedly installed on the inner wall of the temperature control treatment tank 1 and located above the fixed sleeve 3; a treatment ring 5, which is arranged on the inner wall of the fixed sleeve 3; a fixed plate 6, which is fixedly installed on the bottom inner wall of the treatment ring 5; a driving structure, which is arranged on the fixed sleeve 3 and is used to drive the treatment ring 5; two clearance openings 8, which are symmetrically opened on the fixed sleeve 3. The fixed sleeve 3 is located below the processing ring 5; two sets of knocking components are respectively arranged on the inner sides of the two clearance openings 8, and are used to knock the processing ring 5 to generate vibration; the bracket 10 is fixedly installed on the inner wall of the temperature-controlled processing tank 1; the material shifting component is arranged on the bracket 10, and is used to shift the raw materials inside the processing ring 5 evenly; the unloading component is arranged on the bottom surface of the fixed plate 6, and is used to lead out the raw materials after vacuum drying; the feeding pipe 13 is arranged on the top surface of the temperature-controlled processing tank 1; the discharging pipe 14 is arranged on the bottom surface of the temperature-controlled processing tank 1; two lifting ears 15 are symmetrically fixedly installed on the outer wall of the temperature-controlled processing tank 1; When the catechol and sodium carbonate in the furanol etherification reaction raw materials are pre-treated with vacuum, the temperature control treatment tank 1 can be installed in the use position through the lifting ear 15, and then the catechol or sodium carbonate raw materials can be added to the temperature control treatment tank 1 through the feeding pipe 13, and the temperature control treatment tank 1 is vacuumed through the vacuum treatment box 2. At the same time, the temperature control treatment tank 1 can control the temperature according to the different needs of drying catechol or sodium carbonate. The working principles and connection methods of the temperature control treatment tank 1 and the vacuum treatment box 2 are existing mature technologies and will not be described in detail here. When vacuum drying is performed, the processing ring 5 can be driven to rotate by the driving structure, and the raw materials Located in the processing ring 5, the processing ring 5 can oscillate during the rotation under the action of the driving structure, so that the raw materials in the processing ring 5 can be lifted and scattered under the action of centrifugal force. At the same time, during the lifting of the raw materials, the raw materials can be moved by the material shifting component, so that the raw materials can be laid more evenly in the processing ring 5. During the oscillation of the processing ring 5, the processing ring 5 can be intermittently knocked by the knocking component, so that the processing ring 5 can be vibrated, further ensuring the uniformity of the laying of the raw materials, so as to quickly dry the raw materials. After drying, the raw materials can be unloaded from the processing ring 5 by the unloading component and discharged through the discharge pipe 14.

[0025] like Figure 2 , Figure 4 , Figure 5As shown, the driving structure includes: a support frame 71, fixedly mounted on the inner side wall of the fixed sleeve 3; a servo motor 72, fixedly mounted on the top surface of the support frame 71; a connecting telescopic rod 73, fixedly mounted on the output end of the servo motor 72, and the telescopic end of the connecting telescopic rod 73 is fixedly connected to the bottom surface of the fixed plate 6; a corrugated guide port 74, opened on the fixed sleeve 3, and the height of the processing ring 5 is at least twice the distance from the highest point to the lowest point of the corrugated guide port 74; four connecting rods 75, distributed in an annular array and fixedly mounted on the outer wall of the processing ring 5, and the end of the connecting rod 75 away from the processing ring 5 passes through the corrugated guide port 74; When driving the processing ring 5, the servo motor 72 can be turned on to drive the connecting telescopic rod 73 to rotate. During the rotation of the connecting telescopic rod 73, the processing ring 5 can be driven to rotate in the fixed sleeve 3 through the fixed plate 6. Since the connecting rod 75 on the outer wall of the processing ring 5 is slidably installed in the corrugated guide port 74, the connecting rod 75 can be driven to slide in the corrugated guide port 74 during the rotation of the processing ring 5, thereby driving the processing ring 5 to oscillate in the vertical direction, so as to scatter and lift the raw materials.

[0026] like Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the knocking assembly includes: a rotating shaft 91, rotatably mounted on the inner wall of the yielding opening 8; a transmission gear 92, fixedly sleeved on the outer wall of the rotating shaft 91; two knocking rods 93, respectively fixedly mounted on the two ends of the rotating shaft 91; two knocking heads 94, respectively fixedly mounted on the ends of the two knocking rods 93 away from the rotating shaft 91; a sliding ring 95, slidably mounted on the outer wall of the fixed sleeve 3 at a position below the connecting rod 75; a transmission mechanism, which is arranged on the sliding ring 95; the transmission mechanism includes: an annular groove 96, which is opened on the top surface of the sliding ring 95; four guide blocks 97, which are distributed in an annular array on the inner wall of the annular groove 96; four connecting blocks 98, which are respectively fixedly mounted on the top surfaces of the four guide blocks 97, and the connecting blocks 98 are fixedly sleeved on the connecting rod 75; two connecting plates 99, which are symmetrically fixedly mounted on the bottom surface of the sliding ring 95; two driving racks 910, which are respectively fixedly mounted on the bottom ends of the two connecting plates 99, and the driving racks 910 are meshed with the transmission gear 92 Since the sliding ring 95 is slidably connected to the fixed sleeve 3, and the sliding ring 95 is connected to the connecting rod 75 through the annular groove 96, the guide block 97, and the connecting block 98, the connecting rod 75 can drive the sliding ring 95 to slide back and forth in the vertical direction during the sliding process along the corrugated guide port 74. When the processing ring 5 and the sliding ring 95 slide upward, the driving rack 910 drives the transmission gear 92 and the rotating shaft 91 to rotate, so that the knocking rod 93 and the knocking head 94 rotate downward. When the processing ring 5 and the sliding ring 95 slide downward, the driving rack 910 and the transmission gear 92 can drive the rotating shaft 91, the knocking rod 93 and the knocking head 94 to rotate upward, so as to knock the bottom surface of the processing ring 5, so that the processing ring 5 vibrates, and the raw materials can be further spread evenly on the processing ring 5.

[0027] like Figure 3 , Figure 8 As shown, the material-diverting assembly includes: a connecting gear ring 111, fixedly mounted on one end of the four connecting rods 75 away from the processing ring 5; a linkage gear 112, rotatably mounted on the top of the bracket 10, and the linkage gear 112 is meshed with the connecting gear ring 111; a transmission shaft 113, fixedly mounted on the top surface of the linkage gear 112; a fixed frame 114, fixedly mounted on the top of the fixed sleeve 3; a linkage shaft 115, rotatably mounted on the bottom surface of the fixed frame 114, the linkage shaft 115 and the transmission shaft 113 are connected to each other through a driven wheel and a synchronous belt transmission, and the linkage shaft 115 and the fixed sleeve 3 are coaxially arranged; four cross plates 116, distributed in an annular array and fixedly mounted on the outer wall of the linkage shaft 115; four support rods 117, respectively fixedly mounted on one end of the four cross plates 116 away from the linkage shaft 115; four shifting plates 118, respectively fixedly mounted on the bottom ends of the four support rods 117, and the outer wall of the shifting plates 118 is covered with rubber pads; When the connecting rod 75 slides along the corrugated guide opening 74, the connecting gear ring 111 can be driven to rotate. Since the thickness of the linkage gear 112 is much larger than that of the connecting gear ring 111, the connecting gear ring 111 can always mesh with the linkage gear 112, thereby driving the linkage gear 112 and the transmission shaft 113 to rotate. During the rotation of the transmission shaft 113, the linkage shaft 115 can be driven to rotate through the driven wheel and the synchronous belt. During the rotation of the linkage shaft 113, the cross plate 116, the support rod 117 and the paddle plate 118 connected to the linkage shaft 115 can be used to paddle the lifted raw materials through the paddle plate 118, so that the raw materials are dispersed in the processing ring 5, thereby ensuring that the raw materials in the processing ring 5 are better turned over and the drying efficiency is improved.

[0028] like Figure 8 , Fig. 9As shown, the unloading assembly includes: two mounting brackets 121, which are fixedly mounted on the bottom surface of the fixed plate 6; two rotating rods 122, which are symmetrically rotatably mounted between the opposite sides of the two mounting brackets 121; two supporting plates 123, which are respectively fixedly mounted on the outer walls of the two rotating rods 122; two sealing baffles 124, which are respectively fixedly mounted on the ends of the two supporting plates 123 away from the rotating rods 122; a driving mechanism, which is arranged on the fixed plate 6; the driving mechanism includes: two positioning grooves 125, which are respectively provided on the two rotating rods 122; two arc grooves 126, which are respectively provided on the two rotating rods 122, and the arc grooves 126 are connected to the positioning grooves 125; an electric push rod 127, which is fixedly mounted on the bottom surface of the fixed plate 6; two positioning rods 128, which are symmetrically fixedly mounted on the telescopic ends of the electric push rod 127, and the ends of the two positioning rods 128 are respectively located on the inner sides of the two positioning grooves 125 After the raw materials in the processing ring 5 are dried, the electric push rod 127 can be opened and shortened to drive the positioning rod 128 to slide along the positioning groove 125 and the arc groove 126. During the sliding of the positioning rod 128 along the arc groove 126, the two rotating rods 122, the support plate 123 and the sealing baffle 124 can be driven to rotate along the mounting frame 121, so that the sealing baffle 124 is separated from the fixed plate 6 and the processing ring 5. At this time, the raw materials in the processing ring 5 can slide down under the action of gravity and be discharged through the discharge pipe 14, and the sealing baffle 124 can cover the servo motor 72 and the like when it is opened to avoid blocking the unloading of the raw materials. After the unloading is completed, the electric push rod 127 can be extended to drive the sealing baffle 124 to reset so that it can continue to be used.

[0029] A method for pretreating raw materials for furan phenol etherification reaction, according to the above-mentioned device for pretreating raw materials for furan phenol etherification reaction, comprises the following steps: Step 1: Install the temperature-controlled treatment tank 1 at the use position through the lifting ear 15, add the raw material of catechol or sodium carbonate into the temperature-controlled treatment tank 1 through the feeding pipe 13, turn on the servo motor 72, and drive the fixed plate 6 and the treatment ring 5 to rotate in the fixed sleeve 3 by connecting the telescopic rod 73, and the connecting rod 75 on the outer wall of the treatment ring 5 slides in the corrugated guide port 74, so that the treatment ring 5 oscillates in the vertical direction while rotating, so as to spread and lift the raw materials; Step 2: When the connecting rod 75 slides in the corrugated guide port 74, it drives the sliding ring 95 to slide back and forth in the vertical direction. The driving rack 910 on the sliding ring 95 drives the transmission gear 92 and the rotating shaft 91 to rotate, so that the knocking rod 93 and the knocking head 94 intermittently knock on the bottom surface of the processing ring 5 to generate vibration, thereby ensuring that the raw materials are evenly laid on the processing ring 5; Step 3: During the sliding process, the connecting rod 75 also drives the connecting gear ring 111 to rotate, and drives the transmission shaft 113 to rotate through the linkage gear 112, and drives the linkage shaft 115 to rotate through the driven wheel and the synchronous belt, and the cross plate 116, the support rod 117 and the paddle plate 118 on the linkage shaft 115 rotate accordingly, and the raised raw materials are dialed through the paddle plate 118 to ensure that the raw materials are evenly dispersed in the processing ring 5, thereby improving the drying efficiency; Step 4: After drying is completed, turn on the electric push rod 127 to shorten it, and the positioning rod 128 drives the rotating rod 122, the supporting plate 123 and the sealing baffle 124 to rotate along the mounting frame 121, so that the sealing baffle 124 is separated from the processing ring 5 and the fixing plate 6. The raw materials in the processing ring 5 are discharged through the discharge pipe 14 under the action of gravity. After unloading is completed, the electric push rod 127 extends to drive the sealing baffle 124 to reset so that it can continue to be used.
