Description

Technical Field

[0001] This utility model relates to the technical field of ethyl chrysanthemate processing equipment, specifically a desolventizing device for the production of ethyl chrysanthemate. Background Technology

[0002] Ethyl chrysanthemate is a colorless or pale yellow transparent liquid, insoluble in water but soluble in organic solvents such as ethanol, methanol, acetone, benzene, and toluene. In existing technologies, it is mainly synthesized by reacting ethyl diazonoacetate with 2,5-dimethyl-2,4-hexadiene using equipment such as a solvent stripping tower. In the later stages of the production process, in order to further improve the purity of the obtained ethyl chrysanthemate, the ethyl chrysanthemate produced by the solvent stripping tower is usually bottled, transported, and then placed in a distillation kettle for vacuum distillation to obtain high-purity ethyl chrysanthemate.

[0003] However, due to the volatility and flammability of ethyl chrysanthemate, the open-type filling method used in the existing technology would pose a safety hazard. Furthermore, the vapors generated by the volatilization of ethyl chrysanthemate are also highly harmful to the human body and require further protective measures. Therefore, in view of the above, the applicant will provide a solvent removal device for the production of ethyl chrysanthemate to solve the problems existing in the prior art. Utility Model Content

A reinforcing seat is fixed to the bottom of the support. A semi-open annular sleeve is installed on one side of the reinforcing seat, fitting into one end of the discharge solenoid valve pipe. Open slots are provided at both the front and rear ends of one side of the semi-open annular sleeve. A hollow base plate, a brake servo motor, and a suction pump are installed inside the semi-open annular sleeve. A [missing information - likely a device or component] is installed on the outer side of the output end of the brake servo motor. A transition tube is fixedly fitted inside the middle of the hollow base plate. A linkage block is installed between the inner wall of the transition tube and the output end of the brake servo motor, so that the hollow base plate reciprocates under the transmission of the brake servo motor through the transition tube and the linkage block. Several negative pressure stations are set on the top of the hollow base plate along its circumference. The input end of the suction pump is connected to a transition sleeve, and the inner side of the transition sleeve is fitted on the outer side of the transition tube through a bearing and communicates with the interior of the hollow base plate through the transition tube. The output end of the suction pump is connected to a purification guide pipe.

[0006] Preferably, the negative pressure station is composed of a plurality of negative pressure holes arranged in a manner, and the negative pressure holes penetrate the top structure of the hollow bottom plate and communicate with the internal space of the hollow bottom plate.

[0007] Preferably, both the housing surface of the brake servo motor and the housing surface of the air pump are equipped with support seats, and the bottom of the support seats is fixed to the top surface of the reinforcing seat.

[0008] Preferably, a first sealing ring is nested at the fitting point between the bottom inner side of the transition sleeve and the output end of the brake servo motor, and a second sealing ring is fixed on the top surface of the transition sleeve, which can fit and contact the bottom surface of the hollow base plate.

[0009] Preferably, a fluid flow meter is installed at one end of the discharge solenoid valve tube, and one end of the discharge solenoid valve tube is continuously fitted inside the top of the semi-open annular sleeve, and the port of one end of the discharge solenoid valve tube is aligned with the middle of a corresponding negative pressure station.

[0011] Preferably, the bottom of the sealing plate is in contact with the top surface of the hollow bottom plate, and there is a clearance space between the sealing plate and the negative pressure station closest to it.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the combined use of a semi-open annular sleeve, a hollow bottom plate, a brake servo motor, and multiple negative pressure stations inside the hollow bottom plate, allows the brake servo motor to adjust the rotation of the hollow bottom plate, thereby adjusting the filling operation of the packaging barrel relative to the discharge solenoid valve pipe into a relatively closed space formed by the semi-open annular sleeve and the hollow bottom plate. This initially improves the safety of the filling process. During the filling process, the suction pump, through the flow channel space formed by the unused negative pressure stations, transition pipes, transition sleeves, and purification guide pipes, guides the exhaust gas to the designated purification device, further improving the safety of the packaging barrel during the filling process and solving the problems existing in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4A solvent removal device for the production of ethyl chrysenolate includes a solvent removal tower 1, a discharge solenoid valve pipe 2 installed at the bottom of the solvent removal tower 1, and a support 3. A reinforcing seat 4 is fixed to the bottom of the support 3. A semi-open annular sleeve 5, fitted to one end of the discharge solenoid valve pipe 2, is installed on one side of the reinforcing seat 4. Open slots 11 are provided at both the front and rear ends of one side of the semi-open annular sleeve 5. A hollow base plate 6, a brake servo motor 7, and a suction pump 10 are installed inside the semi-open annular sleeve 5. A transition pipe 17, fixedly fitted into the middle of the hollow base plate 6, is installed outside the output end of the brake servo motor 7. Support seats are installed on the surface of the housing of the brake servo motor 7 and the housing of the suction pump 10. The bottom of the base is fixed to the top surface of the reinforcing base 4, thereby ensuring the stability and reliability of the brake servo motor 7 and the suction pump 10 during continuous use. A linkage block 18 is installed between the inner wall of the transition tube 17 and the output end of the brake servo motor 7, so that the hollow base plate 6 rotates back and forth under the transmission of the brake servo motor 7 through the transition tube 17 and the linkage block 18. Several negative pressure stations 9 are set along the circumference of the top of the hollow base plate 6. The input end of the suction pump 10 is connected to the transition sleeve 19, and the inner side of the transition sleeve 19 is fitted on the outer side of the transition tube 17 through the bearing and communicates with the interior of the hollow base plate 6 through the transition tube 17. The output end of the suction pump 10 is connected to the purification guide pipe 12.

[0023] The transition sleeve 19 has a first sealing ring nested at the fitting point between its bottom inner side and the output end of the brake servo motor 7. This improves the sealing effect between the negative pressure station 9 and the output end of the brake servo motor 7 without interfering with the rotation output of the brake servo motor 7. The top surface of the transition sleeve 19 is fixed with a second sealing ring that can fit and contact the bottom surface of the hollow base plate 6. This improves the sealing effect between the hollow base plate 6 and the negative pressure station 9 without interfering with the rotation operation of the hollow base plate 6.

[0024] The negative pressure station 9 is composed of several negative pressure holes arranged in a row. The negative pressure holes penetrate the top structure of the hollow bottom plate 6 and communicate with the internal space of the hollow bottom plate 6. This strengthens the connection of the packaging barrel 8 supported on the top of the hollow bottom plate 6 by negative suction, improving the stability of the hollow bottom plate 6 driving the packaging barrel 8 to rotate during filling. At the same time, the negative pressure station 9 without the packaging barrel 8 can provide a clearance channel for the suction pump 10 to actively guide the ethyl chrysanthemate vapor inside the semi-open annular sleeve 5, so that the ethyl chrysanthemate vapor inside the semi-open annular sleeve 5 can be actively and quickly discharged by the suction pump 10, improving the safety of the filling operation.

[0025] A flow meter 16 is installed at one end of the discharge solenoid valve tube 2, thereby providing real-time monitoring for quantitative filling and ensuring the quantitative conveying and filling effect of the discharge solenoid valve tube 2. One end of the discharge solenoid valve tube 2 is continuously fitted inside the top of the semi-open annular sleeve 5, thereby reducing the filling distance between the discharge solenoid valve tube 2 and the top port of the packaging barrel 8 without interfering with the rotation and movement of the packaging barrel 8. Furthermore, the port of one end of the discharge solenoid valve tube 2 is aligned with the middle of a corresponding negative pressure station 9, ensuring a stable filling effect.

[0026] In use, the packaging barrel 8 to be filled is placed on top of the negative pressure station 9 in the open space of the semi-open annular sleeve 5. The suction pump 10 is started, and the suction pump 10 draws air between the top of the negative pressure station 9 and the bottom of the packaging barrel 8 through the flow channel formed by the transition sleeve 19, the transition pipe 17 and the internal space of the hollow bottom plate 6. A continuous negative suction effect is formed in several negative pressure holes inside the negative pressure station 9, which improves the connection strength between the packaging barrel 8 and the hollow bottom plate 6.

[0027] After the packaging drum 8 stabilizes, the brake servo motor 7 is started. The output end of the brake servo motor 7 drives the hollow bottom plate 6 and the packaging drum 8 to rotate synchronously through the combination of the linkage block 18 and the transition pipe 17. The two open slots 11 provide space for the packaging drum 8 to enter and exit the internal space of the semi-open annular sleeve 5 until the packaging drum 8 is located below the port of one end of the discharge solenoid valve pipe 2. After completion, the brake servo motor 7 is temporarily closed, and the solenoid valve inside the discharge solenoid valve pipe 2 is opened. Ethyl chrysanthemate produced in the desolventizing tower 1 enters the packaging drum 8 through the discharge solenoid valve pipe 2. At the same time, the flow meter 16 monitors the flow rate of ethyl chrysanthemate output from the discharge solenoid valve pipe 2 in real time. After the output of the discharge solenoid valve pipe 2 reaches the preset value, the solenoid valve inside the discharge solenoid valve pipe 2 is closed.

[0028] During the specific output process of the discharge solenoid valve pipe 2, the vapor of ethyl chrysanthemate diffused into the semi-open annular sleeve 5 will be actively guided to the hollow bottom plate 6 through the unused negative pressure station 9. Then, through the flow channel space formed by the transition pipe 17, the transition sleeve 19 and the purification guide pipe 12, and in cooperation with the suction pump 10, the waste gas will be guided to the designated purification device, such as the existing activated carbon box.

[0029] After a single packaging drum 8 is filled and used, the brake servo motor 7 is restarted. The output end of the brake servo motor 7 drives the hollow bottom plate 6 and the packaging drum 8 to rotate synchronously through the combination formed by the linkage block 18 and the transition tube 17 until the packaging drum 8 is back in the open space of the semi-open annular sleeve 5. Then, the top space of the packaging drum 8 is immediately sealed, such as by threaded sealing cap or heat-sealing protective film followed by threaded sealing cap.

[0030] Please see Figures 1-5 An assembly space is provided in the middle of the semi-open annular sleeve 5. An auxiliary support 13 is installed in the assembly space. Electric push rods 14 are installed at the top and bottom of the auxiliary support 13. The output end of the electric push rod 14 is connected to a sealing plate 15. Under the transmission of their respective electric push rods 14, the two sealing plates 15 can close and adjust the two open slots 11 in the semi-open annular sleeve 5. This serves as an auxiliary condition to further improve the purification effect of the suction pump 10. The bottom of the sealing plate 15 is in close contact with the top surface of the hollow base plate 6 to improve the connection effect. There is also a clearance space between the sealing plate 15 and the negative pressure station 9 closest to it to avoid structural interference.

[0031] In use, considering the need for the suction pump 10 to enhance the suction flow of the mixed gas inside the semi-open annular sleeve 5, after the filling operation is carried out, the two electric push rods 14 are started. The output ends of the two electric push rods 14 drive their respective sealing plates 15 to automatically move until the two sealing plates 15 seal the two open slots 11 inside the semi-open annular sleeve 5. This further enhances the active absorption and drainage effect of the suction pump 10 on the internal space of the semi-open annular sleeve 5, and further enhances the treatment effect of ethyl chrysanthemum vapor inside the semi-open annular sleeve 5.
