Description

Technical Field

[0001] The present invention belongs to the technical field of thiophene purification, and specifically relates to a device and a method for purifying thiophene. Background Art

[0002] Thiophene is an important heterocyclic compound widely used in medicine, pesticides, dyes, and organic materials. In industrial production or laboratory synthesis, thiophene often coexists with other organic compounds, so efficient purification technology is required to obtain high-purity products. Currently, in the existing work of purifying thiophene, distillation is usually used to purify thiophene. During the distillation process of thiophene, the distilled steam needs to be condensed through a condenser and then collected. Since thiophene is often in a static state with other organic matter in the distillation box, thiophene is easily decomposed due to local high temperature, making it difficult to achieve uniform temperature distribution in the system, affecting the transfer rate of thiophene molecules from the liquid phase to the gas phase. Moreover, during the condensation and collection process, the collection bottle needs to be frequently replaced with human assistance, and the liquid outlet of the condenser needs to be stopped during the replacement process. During this process, no liquid collection work is performed. Therefore, when using the collection bottle to collect the purified thiophene in batches, the workload is increased and the collection efficiency is greatly reduced. Summary of the Invention

[0011] A method for using a device for purifying thiophene, the method comprising the following steps: When the distillation box is distilling the thiophene inside, the thiophene molecules are converted into gas phase and rise. The steam containing thiophene molecules enters the liquid guide tube through the plug connector. The liquid guide tube guides the steam into the condenser. The water inlet and outlet ends outside the condenser are connected to the cooling water circulation system, so that the steam in the condenser is condensed into liquid. The liquid flows into the telescopic tube through the condenser. At this time, the solenoid valve is closed, so that the liquid will not drip out from the dripping head through the telescopic tube. The feeding and conveying mechanism is used to convey the collecting bottle to the right, so that the collecting bottle enters the interior through the feed port on the left side of the support rack, so that the bottom of the collecting bottle overlaps with the roller, and at the same time the collecting bottle enters the leftmost clamp. The arc-shaped clamp limits the collecting bottle to improve the stability of the collection bottle installation; Secondly, the motor is controlled to work so that the output shaft of the motor drives the sliding column to rotate through the turntable. The sliding column will push the deflection seat to rotate during the process of sliding into the slide, so that the deflection seat drives the stirring rod on the top to rotate through the rotating shaft, and the stirring rod drives multiple sets of blades to rotate inside the distillation box, and stirs the thiophene material inside the distillation box through the blades, thereby improving the fluidity of the thiophene material inside the distillation box, making the thiophene material heated evenly, and increasing the transfer rate of thiophene molecules from the liquid phase to the gas phase. At the same time, the rotating shaft will drive the rotating ring to rotate counterclockwise outside the support bearing through multiple fixed rods, and support and limit the rotating ring through the support bearing, thereby improving the stability of the rotation of the fixture driven by the turntable. Since the leftmost collecting bottle is located in the fixture, the fixture will push the collecting bottle to rotate in the bracket, and the bottom and outer wall of the collecting bottle are supported and guided by the rollers and guide wheels inside the bracket respectively, thereby improving the stability of the collection bottle transfer and reducing the friction generated by the collection bottle during movement, thereby protecting the collection bottle. When the sliding post on the turntable is separated from the slide, the deflection seat rotates forty-five degrees. Similarly, the rotating shaft rotates forty-five degrees counterclockwise through the fixed rod and the swivel. At this time, the arc plate on the turntable is slidably connected in the arc groove. The arc groove limits the arc plate in the rotating state, so that when the sliding post is separated from the slide, the deflection seat itself will not rotate freely, thereby improving the stability of the clamp in adjusting the position of the collection bottle. In the current state, the loading and conveying mechanism works again to push the next collection bottle into the bracket. As the turntable drives the sliding post to slide into the slide again, the deflection seat drives the swivel to rotate forty-five degrees counterclockwise through the rotating shaft and the fixed rod again, until the clamp drives the collection bottle to move to the bottom of the condensation component; By controlling the extension of the electric push rod to drive the fixed plate to move downward, the fixed plate drives the dripping head downward through the telescopic tube. The telescopic tube is extended while ensuring the normal circulation of the internal liquid until the dripping head is inserted into the one-way valve on the top of the collection bottle. Then, the solenoid valve on the dripping head is opened to allow the liquid in the condenser to enter the collection bottle through the telescopic tube and the dripping head. After the purification and collection of thiophene is completed, the solenoid valve is closed, and the electric push rod is controlled to contract to drive the fixed plate upward. The fixed plate drives the dripping head to move upward and disengage from the one-way valve. The top of the one-way valve is in a closed state without pressure, thereby isolating the liquid inside the collection bottle from the outside world. Secondly, the deflection seat continues to rotate, and drives the clamp to rotate through the rotating shaft and the swivel ring. The clamp drives the filled collection bottle to transfer to the right in the support rack. When the collection bottle moves to the drop-out port on the right side of the support rack, the collection bottle is separated from the support rack and contacts the unloading conveying mechanism, and the collection bottle is conveyed to the right by the unloading conveying mechanism. As described above, during the condensation collection process, there is no need to frequently replace the collection bottle with human assistance. The continuity of the condensation collection work is ensured by automatically switching the collection bottle.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the collecting bottle is limited by the clamp to improve the stability of the collecting bottle mounting. The rotating shaft drives the swivel to rotate counterclockwise outside the supporting bearing through multiple fixed rods, so that the clamp will push the collecting bottle to rotate in the bracket. The bottom and outer wall of the collecting bottle are supported and guided by the rollers and guide wheels inside the bracket respectively, thereby improving the stability of the collecting bottle transfer and reducing the friction generated by the collecting bottle when moving, thereby protecting the collecting bottle. In the current state, the feeding and conveying mechanism works again to push the next collecting bottle into the bracket. As the turntable drives the sliding column to slide into the slide again, the deflection seat drives the swivel to rotate forty-five degrees counterclockwise again through the rotating shaft and the fixed rod until the clamp drives the collecting bottle. The bottle moves to the bottom of the condensation assembly. After the thiophene is purified and collected by the condensation assembly, the deflection seat continues to rotate, and the clamp is driven to rotate by the rotating shaft and the swivel. The clamp drives the filled collection bottle to transfer to the right in the support rack. When the collection bottle moves to the drop port on the right side of the support rack, the collection bottle is separated from the support rack and contacts the unloading conveying mechanism. The collection bottle is conveyed to the right by the unloading conveying mechanism. Based on the above operation, during the condensation collection process, there is no need to frequently replace the collection bottle with human assistance. The continuity of the condensation collection work is ensured by automatically switching the collection bottle. Therefore, when the collection bottle is used to collect the purified thiophene in batches, the workload is reduced while the collection efficiency is improved. 2. In the present invention, a stirring rod at the top is driven to rotate by a rotating shaft, which in turn drives multiple sets of blades to rotate inside the distillation box. The blades stir the thiophene material inside the distillation box, thereby improving the fluidity of the thiophene material inside the distillation box, uniformly heating the thiophene material, and increasing the transfer rate of thiophene molecules from the liquid phase to the gas phase. The electric push rod is controlled to extend to drive the fixed plate to move downward. The fixed plate drives the dripping head downward through the telescopic tube. The telescopic tube is extended while ensuring normal circulation of the internal liquid until the dripping head is inserted into the one-way valve at the top of the collection bottle. Then, the solenoid valve on the dripping head is opened, allowing the liquid in the condenser to enter the collection bottle through the telescopic tube and the dripping head. After the purification and collection of thiophene is completed, the solenoid valve is closed, and the electric push rod is controlled to retract to drive the fixed plate upward. The fixed plate drives the dripping head upward and disengages the one-way valve. The top of the one-way valve is closed when not under pressure, thereby isolating the liquid inside the collection bottle from the outside, preventing thiophene from volatilizing and causing safety hazards, and improving the safety of the purification and collection work.

DETAILED DESCRIPTION

[0014] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0015] like Figure 1-6 As shown, the present invention provides a technical solution: a device for purifying thiophene, comprising a distillation box 1, a box cover 2 is installed on the top of the distillation box 1, a support rack 3 is provided below the outside of the distillation box 1, a feed port 4 and a discharge port 5 are respectively provided on both sides of the support rack 3, a loading conveying mechanism 6 is provided on the side of the feed port 4 away from the distillation box 1, a discharge conveying mechanism 7 is provided on the side of the discharge port 5 away from the distillation box 1, the discharge conveying mechanism 7 is located below the discharge port 5, a material guide component 8 is provided in the middle of the support rack 3, and the material guide component 8 is clamped. Connected to the lower side of the outer wall of the distillation box 1, a plurality of collecting bottles 9 are provided in the bracket 3. The bracket 3 is annular in design and has an annular groove 13 at the bottom. A plurality of rollers 14 are installed at equal intervals in the annular groove 13. A plurality of guide wheels 15 are installed at equal intervals on the side walls of the bracket 3. The bottom and outer wall of the collecting bottles 9 are in contact with the rollers 14 and the guide wheels 15 respectively. A support leg 16 is fixedly connected to the bottom of the bracket 3. A base 17 is fixed to the bottom of the support leg 16. The drive assembly 12 is mounted on the base 17. During operation, the collecting bottle 9 enters the interior through the feed port 4 on the left side of the bracket 3, so that the bottom of the collecting bottle 9 overlaps with the roller 14. The roller 14 and the guide wheel 15 inside the bracket 3 respectively support and guide the bottom and outer wall of the collecting bottle 9, thereby improving the stability of the transfer of the collecting bottle 9 and reducing the friction generated by the collecting bottle 9 when moving, thereby playing a role in protecting the collection bottle 9 during transportation.

[0016] The material guide assembly 8 includes a rotating ring 801. A support bearing 802 is fixed to the inner wall of the rotating ring 801. The inner ring of the support bearing 802 is fixed to the outer wall of the distillation box 1. A plurality of fixing rods 803 are fixed to the bottom of the inner wall of the rotating ring 801. The adjacent ends of the fixing rods 803 are fixed to the outside of the driving assembly 12. Eight groups of clamps 804 are fixed at equal intervals above the outer wall of the rotating ring 801. Each group of clamps 804 has three clamps 804, and the three clamps 804 are of an arc-shaped design. The collection bottle 9 is clamped into a corresponding group of clamps 804. The arc-shaped clamps 804 limit the collection bottle 9 and improve the stability of the collection bottle 9. During operation, the driving assembly 12 drives the swivel 801 to rotate counterclockwise outside the support bearing 802 through multiple fixing rods 803, and the swivel 801 is supported and limited by the support bearing 802, thereby improving the stability of the rotation of the fixture 804 driven by the turntable 122; A one-way valve 10 is installed on the top of the collecting bottle 9, and a condensation assembly 11 is provided above one of the collecting bottles 9. One end of the top of the condensation assembly 11 is installed on the box cover 2 and is connected to the interior of the distillation box 1. The condensation assembly 11 includes a condenser pipe 111. The top of the condenser pipe 111 is connected to a liquid guide pipe 112. The other end of the liquid guide pipe 112 is plugged with a plug connector 113. The plug connector 113 is installed on the box cover 2. Two fixing seats 114 are fixed to the outside of the condenser pipe 111. The fixing seat 114 is fixed to the outer wall of the distillation box 1. Because the liquid guide pipe 112 and the plug connector 113 are plug-in connected, the liquid guide pipe 112 can be removed from the box cover 2, which is convenient for opening the box cover 2 to process the interior of the distillation box 1. The bottom of the condenser 111 is connected to a telescopic tube 115. The outer wall of the telescopic tube 115 is clamped with a clamping ring 116 and a fixing plate 118. The clamping ring 116 is fixed to the outside of the distillation box 1. The bottom end of the telescopic tube 115 passes through the fixing plate 118 and is installed with a dripping head 117. A solenoid valve is installed between the dripping head 117 and the telescopic tube 115. The dripping head 117 is located directly above one of the collecting bottles 9. The bottom of the clamping ring 116 is fixed to an electric push rod 119, and the bottom end of the electric push rod 119 is fixed to the fixing plate 118. During operation, the electric push rod 119 extends to drive the fixed plate 118 to move downward, and the fixed plate 118 drives the dripping head 117 to move downward through the telescopic tube 115. The telescopic tube 115 extends while ensuring the normal circulation of the internal liquid until the dripping head 117 is inserted into the one-way valve 10 at the top of the collecting bottle 9. Then, the solenoid valve on the dripping head 117 is opened, so that the liquid in the condenser 111 enters the collecting bottle 9 through the telescopic tube 115 and the dripping head 117. The electric push rod 119 contracts and drives the fixed plate 118 to move upward, and the fixed plate 118 drives the drip head 117 to move upward and disengage from the one-way valve 10. The top of the one-way valve 10 is in a closed state when not under pressure, thereby isolating the liquid inside the collecting bottle 9 from the outside world, preventing thiophene from volatilizing and causing safety hazards.

[0017] The bottom of the material guide assembly 8 is fixedly connected to a drive assembly 12. The middle portion of the drive assembly 12 is installed through the bottom of the distillation box 1. The drive assembly 12 includes a motor 121, which is fixed to the base 17. A turntable 122 is fixed to the output shaft of the motor 121. A deflection seat 124 is provided on one side of the turntable 122. Eight arcuate grooves 125 and eight slideways 126 are evenly spaced outside the deflection seat 124. The eight arcuate grooves 125 and the eight slideways 126 are staggered with each other. One of the arcuate grooves 125 contacts the arc plate on the turntable 122. A sliding post 123 is fixed to the edge of the turntable 122. The sliding post 123 is slidably connected to one of the slideways 126. By rotating the fixing rod 803 and the rotating ring 801 counterclockwise forty-five degrees, the arc plate on the turntable 122 is slidably connected in the arc groove 125. The arc groove 125 limits the arc plate in the rotating state, so that when the sliding column 123 disengages from the slide 126, the deflection seat 124 itself will not rotate freely, thereby improving the stability of the clamp 804 in adjusting the position of the collecting bottle 9.

[0018] A rotating shaft 127 is fixed to the middle of the deflection seat 124, and the bottom end of the rotating shaft 127 is installed on the base 17 through a sleeve. The outer wall of the rotating shaft 127 is installed on the bottom of the distillation box 1 through a sealed bearing. The top of the rotating shaft 127 passes through the distillation box 1 and is fixed with a stirring rod 128. Two sets of blades 129 are fixed outside the stirring rod 128. The stirring rod 128 at the top is driven to rotate by the rotating shaft 127, and the stirring rod 128 drives multiple sets of blades 129 to rotate inside the distillation box 1. The thiophene material inside the distillation box 1 is stirred by the blades 129, thereby improving the fluidity of the thiophene material inside the distillation box 1, making the thiophene material heated evenly, and improving the transfer rate of thiophene molecules from the liquid phase to the gas phase.

[0019] A method for using a device for purifying thiophene, the method comprising the following steps: When the distillation box 1 is distilling the thiophene inside, the thiophene molecules are converted into the gas phase and rise. The steam containing the thiophene molecules enters the liquid guide pipe 112 through the plug joint 113. The liquid guide pipe 112 guides the steam into the condenser 111. The water inlet and outlet ends outside the condenser 111 are connected to the cooling water circulation system, so that the steam in the condenser 111 is condensed into liquid. The liquid flows into the telescopic pipe 115 through the condenser 111. At this time, the solenoid valve is closed, so that the liquid will not drip out from the drip head 117 through the telescopic pipe 115. The collecting bottle 9 is transported to the right by the feeding and conveying mechanism 6, so that the collecting bottle 9 enters the interior through the feed port 4 on the left side of the supporting rack 3, so that the bottom of the collecting bottle 9 overlaps with the roller 14, and at the same time, the collecting bottle 9 enters the leftmost clamp 804. The arc-shaped clamp 804 limits the collecting bottle 9, thereby improving the stability of the collection bottle 9. Secondly, the motor 121 is controlled to work so that the output shaft of the motor 121 drives the slide 123 to rotate through the turntable 122. The slide 123 pushes the deflection seat 124 to rotate in the process of sliding into the slide 126, so that the deflection seat 124 drives the stirring rod 128 on the top to rotate through the rotating shaft 127. The stirring rod 128 drives multiple sets of blades 129 to rotate inside the distillation box 1. The blades 129 stir the thiophene material inside the distillation box 1, thereby improving the fluidity of the thiophene material inside the distillation box 1, making the thiophene material evenly heated, and increasing the transfer rate of thiophene molecules from the liquid phase to the gas phase. At the same time, the rotating shaft 1 27 drives the rotating ring 801 to rotate counterclockwise outside the support bearing 802 through multiple fixing rods 803, and the supporting bearing 802 supports and limits the rotating ring 801, thereby improving the stability of the rotation of the clamp 804 driven by the turntable 122. Since the leftmost collecting bottle 9 is located in the clamp 804, the clamp 804 will push the collecting bottle 9 to rotate in the bracket 3. The roller 14 and guide wheel 15 inside the bracket 3 respectively support and guide the bottom and outer wall of the collecting bottle 9, thereby improving the stability of the transfer of the collecting bottle 9 and reducing the friction generated by the collecting bottle 9 during movement, thereby protecting the collecting bottle 9. When the sliding post 123 on the turntable 122 disengages from the slide 126, the deflection seat 124 rotates forty-five degrees. Similarly, the rotating shaft 127 rotates forty-five degrees counterclockwise through the fixed rod 803 and the rotating ring 801. At this time, the arc plate on the turntable 122 is slidably connected to the arc groove 125, and the arc groove 125 limits the arc plate in the rotating state, so that when the sliding post 123 disengages from the slide 126, the deflection seat 124 itself will not rotate freely, thereby improving the stability of the clamp 804 in adjusting the position of the collecting bottle 9. In the current state, the loading conveying mechanism 6 works again to push the next collecting bottle 9 into the supporting rack 3. As the turntable 122 drives the sliding post 123 to slide into the slide 126 again, the deflection seat 124 drives the rotating ring 801 to rotate forty-five degrees counterclockwise through the rotating shaft 127 and the fixed rod 803 again, until the clamp 804 drives the collecting bottle 9 to move to just below the condensation component 11; By controlling the extension of the electric push rod 119 to drive the fixed plate 118 to move downward, the fixed plate 118 drives the dripping head 117 to move downward through the telescopic tube 115. The telescopic tube 115 is extended while ensuring the normal circulation of the internal liquid until the dripping head 117 is inserted into the one-way valve 10 on the top of the collecting bottle 9. Then, the solenoid valve on the dripping head 117 is opened to allow the liquid in the condenser 111 to enter the collecting bottle 9 through the telescopic tube 115 and the dripping head 117. After the purification and collection of thiophene is completed, the solenoid valve is closed, and the electric push rod 119 is controlled to contract to drive the fixed plate 118 to move upward. The fixed plate 118 drives the dripping head 117 to move upward and disengage from the one-way valve 10. The top of the one-way valve 10 is in a closed state without pressure, thereby isolating the liquid inside the collecting bottle 9 from the outside world. Secondly, the deflection seat 124 continues to rotate, and drives the clamp 804 to rotate through the rotating shaft 127 and the rotating ring 801. The clamp 804 drives the filled collecting bottle 9 to transfer to the right in the supporting rack 3. When the collecting bottle 9 moves to the drop-out port 5 on the right side of the supporting rack 3, the collecting bottle 9 is separated from the supporting rack 3 and contacts the unloading conveying mechanism 7. The collecting bottle 9 is conveyed to the right by the unloading conveying mechanism 7. As described above, during the condensation collection process, there is no need to frequently replace the collecting bottle 9 with human assistance. The continuity of the condensation collection work is ensured by automatically switching the collecting bottle 9.

8. A method for using a device for purifying thiophene, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: When the distillation box (1) is distilling the internal thiophene, the thiophene molecules are converted into the gas phase and rise. The steam containing the thiophene molecules enters the liquid guide tube (112) through the plug connector (113). The liquid guide tube (112) guides the steam into the condenser (111). The water inlet and outlet ends outside the condenser (111) are connected to the cooling water circulation system, so that the steam in the condenser (111) is condensed into liquid. The liquid flows into the telescopic tube (115) through the condenser (111). At this time, the solenoid valve is closed. , so that the liquid will not drip out from the drip head (117) through the telescopic tube (115), and the collecting bottle (9) is transported to the right by the feeding and conveying mechanism (6), so that the collecting bottle (9) enters the interior through the feeding port (4) on the left side of the supporting frame (3), so that the bottom of the collecting bottle (9) overlaps with the roller (14), and at the same time, the collecting bottle (9) enters the leftmost clamp (804), and the arc-shaped clamp (804) limits the collecting bottle (9), thereby improving the stability of the collection bottle (9) installation; Secondly, the motor (121) is controlled to work, so that the output shaft of the motor (121) drives the sliding column (123) to rotate through the turntable (122). The sliding column (123) pushes the deflection seat (124) to rotate in the process of sliding into the slideway (126), so that the deflection seat (124) drives the stirring rod (128) on the top to rotate through the rotating shaft (127). The stirring rod (128) drives multiple sets of blades (129) to rotate inside the distillation box (1). The blades (129) stir the thiophene material inside the distillation box (1), thereby improving the fluidity of the thiophene material inside the distillation box (1), making the thiophene material evenly heated, and increasing the transfer rate of thiophene molecules from the liquid phase to the gas phase. At the same time, the rotating shaft (127) The rotating ring (801) is driven to rotate counterclockwise outside the support bearing (802) through multiple fixed rods (803), and the rotating ring (801) is supported and limited by the support bearing (802), thereby improving the stability of the rotation of the turntable (122) driving the clamp (804). Since the leftmost collecting bottle (9) is located in the clamp (804), the clamp (804) pushes the collecting bottle (9) to rotate in the support rack (3). The bottom and outer wall of the collecting bottle (9) are supported and guided by the roller (14) and the guide wheel (15) inside the support rack (3), respectively, thereby improving the stability of the transfer of the collecting bottle (9) and reducing the friction generated by the collecting bottle (9) when moving, thereby protecting the collecting bottle (9); When the sliding post (123) on the turntable (122) is separated from the slideway (126), the deflection seat (124) rotates forty-five degrees. Similarly, the rotating shaft (127) rotates forty-five degrees counterclockwise through the fixed rod (803) and the rotating ring (801). At this time, the arc plate on the turntable (122) is slidably connected in the arc groove (125). The arc groove (125) limits the arc plate in the rotating state, so that when the sliding post (123) is separated from the slideway (126), the deflection seat (124) itself will not rotate freely, thereby improving the card The tool (804) has the stability of adjusting the position of the collecting bottle (9). In the current state, the feeding conveying mechanism (6) works again to push the next collecting bottle (9) into the supporting rack (3). As the turntable (122) drives the slide column (123) to slide into the slideway (126) again, the deflection seat (124) drives the rotating ring (801) to rotate forty-five degrees counterclockwise again through the rotating shaft (127) and the fixed rod (803) until the clamp (804) drives the collecting bottle (9) to move to the bottom of the condensation assembly (11); By controlling the extension of the electric push rod (119), the fixed plate (118) is driven to move downward, and the fixed plate (118) drives the dripping head (117) to move downward through the telescopic tube (115). The telescopic tube (115) is extended while ensuring the normal circulation of the internal liquid until the dripping head (117) is inserted into the one-way valve (10) at the top of the collection bottle (9). Then, the solenoid valve on the dripping head (117) is opened to allow the liquid in the condenser (111) to enter the collection bottle (9) through the telescopic tube (115) and the dripping head (117). After the purification and collection of thiophene is completed, the solenoid valve is closed, and the electric push rod (119) is controlled to contract to drive the fixed plate (118) to move upward. The fixed plate (118) drives the dripping head (117) to move upward and disengage from the one-way valve (10). The top of the one-way valve (10) is in a closed state without pressure, thereby isolating the liquid inside the collection bottle (9) from the outside. Secondly, the deflection seat (124) continues to rotate, and drives the clamp (804) to rotate through the rotating shaft (127) and the rotating ring (801), and the clamp (804) drives the filled collection bottle (9) to transfer to the right in the support rack (3). When the collection bottle (9) moves to the drop opening (5) on the right side of the support rack (3), the collection bottle (9) is separated from the support rack (3) and contacts the discharge conveying mechanism (7). The collection bottle (9) is conveyed to the right by the discharge conveying mechanism (7). As described above, during the condensation collection process, there is no need to frequently replace the collection bottle (9) with human assistance. The continuity of the condensation collection work is ensured by automatically switching the collection bottle (9).
