[0002] Benzyltoluene, as a high-performance synthetic heat transfer oil, is widely used in chemical, pharmaceutical and other fields. During its production, it produces filtrate containing various impurities. If such filtrate is directly passed into the subsequent purification system, it will not only cause blockage of the distillation column trays and a decrease in the heat transfer efficiency of the heat exchanger, but also affect the purity and performance of the final product due to the participation of impurities in the reaction. Therefore, pretreatment of the filtrate is a key step in ensuring the production quality of benzyltoluene.

[0019] 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.

[0020] Example 1

[0021] Please refer to Figure 1-5 As shown, this utility model provides a pretreatment device for benzyltoluene filtrate, including a pretreatment tank 1. Four sets of support legs 2 are installed at the bottom of the pretreatment tank 1. The top and bottom of the pretreatment tank 1 are respectively provided with an inlet 3 and an outlet 4. Two sets of mounting frames 5 are provided from top to bottom on the inner side of the pretreatment tank 1 near the top. Coarse filter screen 6 and fine filter screen 7 are respectively installed obliquely on the inner side of the two sets of mounting frames 5. Both ends of the mounting frames 5 are provided with connecting plates 8. Both sets of connecting plates 8 are connected to the fixing seats 9 provided on the inner walls of both sides of the pretreatment tank 1 through a snap-fit ​​mechanism that is easy to disassemble and assemble. A temperature control component to improve the stability of benzyltoluene filtrate is provided near the bottom of the pretreatment tank 1.

[0022] Specifically, after the benzyltoluene filtrate enters the pretreatment tank 1 through the inlet 3, it first passes through the inclined coarse filter 6 in the upper mounting frame 5 to filter large particulate impurities, and then passes through the inclined fine filter 7 in the lower mounting frame 5 to filter fine impurities. The two sets of mounting frames 5 are connected to the fixed seats 9 on the inner wall of the pretreatment tank 1 through the connecting plates 8 at both ends and the snap-fit ​​mechanism, which can facilitate disassembly and maintenance. When the filtered filtrate flows through the bottom of the pretreatment tank 1, its temperature can be adjusted by the temperature control component to improve stability. Finally, it can be discharged from the outlet 4. Thus, through the above structure, multiple effects of high-efficiency filtration, convenient maintenance and temperature stability are achieved, which has the advantages of good filtration effect, simple operation and high product stability.

[0023] The coarse filter 6 is made of metal with a mesh size of 50-100, while the fine filter 7 is made of ceramic with a mesh size of 200-300. The 50-100 mesh metal coarse filter 6 can intercept large particles of impurities, and the 200-300 mesh ceramic fine filter 7 can achieve fine filtration. The metal material can ensure the mechanical strength of the primary filtration, while the ceramic material can ensure the accuracy of the final filtration. It has significant advantages such as good graded filtration effect, strong filter durability, and high filtration accuracy.

[0024] The locking mechanism includes a locking ball 16. A fixing cylinder 11 passes through the center of the fixing base 9. A connecting rod 12 is threaded onto the inner side of the fixing cylinder 11. One end of the connecting rod 12 is equipped with a knob 13, and the other end is equipped with an arc-shaped contact head 14. Two sets of placement slots 15 are symmetrically opened on the inner wall of the fixing cylinder 11 near the bottom. The locking ball 16 that abuts against the contact head 14 is placed inside the two sets of placement slots 15. The top of the fixing base 9 is provided with a locking groove 10 that matches the fixing cylinder 11 and the locking ball 16. First, the two sets of connecting plates 8 are placed on the top of the corresponding fixing base 9, and the fixing cylinder 11 is inserted into the locking groove 10. Then, rotating the knob 13 causes the connecting rod 12 to rotate inside the fixed cylinder 11, causing the contact head 14 to press down and push the locking ball 16 outward from the placement groove 15 and into the locking groove 10 of the fixed seat 9, thereby completing the installation and fixing of the mounting frame 5 and the filter screen. When disassembling, rotating the knob 13 in the opposite direction causes the connecting rod 12 to retract, the contact head 14 to release the pressure on the locking ball 16, and the locking ball 16 falls back into the placement groove 15 under the action of gravity, achieving quick unlocking. Then, lifting the mounting frame 5 upwards completes the disassembly of the filter screen. Thus, through the setting, the quick disassembly and assembly function of the filter screen is realized, which has significant advantages such as simple operation, reliable locking, and high maintenance efficiency.

[0025] The pretreatment box 1 has a door 23 on one side of each of the two sets of mounting frames 5. The door 23 on the front of the pretreatment box 1 can be opened directly to inspect, clean or replace the coarse filter 6 and the fine filter 7 without disassembling other parts, which significantly improves the convenience of filter maintenance. Each set of mounting frames 5 is equipped with a flow guide 17. By setting the flow guide 17 above the mounting frames 5, the benzyl toluene filtrate can be effectively guided to fall from the higher end of the coarse filter 6 and the fine filter 7, which has significant advantages such as optimizing the flow field distribution and improving filtration efficiency.

[0026] The temperature control component includes a heat-conducting pipe 19 wound around the outer wall of the pretreatment tank 1. A surrounding plate 18 is provided on the outside of the heat-conducting pipe 19. Both ends of the heat-conducting pipe 19 are provided with connectors 20 to facilitate the entry and exit of the heat transfer medium. A solenoid valve is provided inside the connector 20, and the solenoid valve is electrically connected to a control panel 22 installed on one side of the surrounding plate 18. A temperature sensor 21 is installed at the bottom inside the pretreatment tank 1 and is electrically connected to the control panel 22. The temperature sensor 21 can monitor the temperature of the filtrate at the bottom inside the pretreatment tank 1 in real time and transmit the data to the control panel 22. When the temperature deviates from the preset range... During operation, the control panel 22 can open the solenoid valves inside the connectors 20 at both ends of the heat pipe 19, allowing the heat transfer medium to enter and exit the heat pipe 19 through the connectors 20. The heat pipe 19, which is wrapped around the outer wall of the pretreatment tank 1, can regulate the temperature of the filtrate inside the tank through heat exchange. When the temperature sensor 21 detects that the filtrate temperature has returned to the preset range, the control panel 22 can close the solenoid valves to complete the temperature regulation. In addition, through settings, the temperature of the filtrate inside the pretreatment tank 1 can be monitored and precisely adjusted in real time to ensure that it is stable within a suitable range, avoid the filtrate state affected by temperature fluctuations, and improve the stability of pretreatment quality.

[0027] Working principle: First, benzyl toluene filtrate enters the pretreatment tank 1 through the inlet 3 and is guided by the guide hood 17 to flow upward to the mounting frame 5. It first passes through the inclined metal coarse filter 6 in the upper mounting frame 5 to filter large particles of impurities, and then flows through the inclined ceramic fine filter 7 in the lower mounting frame 5 to filter fine impurities. The filtered filtrate flows to the bottom of the pretreatment tank 1. At this time, the temperature sensor 21 can monitor the filtrate temperature in real time and transmit the data to the control panel 22. If the temperature deviates from the preset range, the control panel 22 can control the solenoid valve inside the connector 20 at both ends of the heat pipe 19 to open. The heat transfer medium enters and exits the heat pipe 19 through the connector 20 and adjusts the filtrate temperature through heat exchange. After the temperature returns to the preset range, the solenoid valve closes, and the finally treated filtrate can be discharged from the outlet 4.

[0028] When disassembling and maintaining the filter screen, first place the two sets of connecting plates 8 on top of the corresponding fixing base 9, and insert the fixing cylinder 11 into the slot 10. Then, rotate the knob 13, which can drive the connecting rod 12 to rotate in the fixing cylinder 11, so that the contact head 14 presses down and pushes the locking ball 16 outward from the placement slot 15 and into the slot 10 of the fixing base 9, thereby completing the installation and fixing of the mounting frame 5 and the filter screen. When disassembling, rotate the knob 13 in the opposite direction to make the connecting rod 12 retract, and the contact head 14 releases the pressure on the locking ball 16. The locking ball 16 falls back into the placement slot 15 under the action of gravity, realizing quick unlocking. Then lift the mounting frame 5 upward to complete the disassembly of the filter screen, so as to facilitate the cleaning and maintenance of the filter screen, and thus complete the entire operation process.
