Description

Technical Field

[0001] The utility model relates to the technical field of operation, in particular to a trifluoromethylthiotrifluorotoluene double distillation device. Background Art

[0002] The distillation equipment is mainly used for the purification of liquid raw materials. Since the boiling points of different components in the mixed liquid are different, the Chinese utility model patent, authorization announcement number "CN219307960U", discloses a combined distillation column and distillation device, wherein the first electric heating block for heating the raw liquid is fixedly embedded in the bottom center of the first-level distillation tube, and the top of the first-level distillation tube is fixedly installed with a coaxially arranged lower docking block, and the top of the lower docking block is fixedly installed with a coaxially arranged secondary distillation tube and a second electric heating block. The double distillation structure is formed by the first-level distillation tube and the second-level distillation tube, thereby improving the extraction accuracy of the device for different components in the mixed solution, and the water-cooling structure accelerates the condensation speed of the steam, thereby improving the work efficiency, and the device can recycle the waste heat of the steam.

[0003] The above technical solution can send the liquid into the second cooling tube through the pump function. At this time, the water in the second cooling tube can accelerate the condensation of steam in the collecting tube, so that the hot water in the sleeve can preheat the liquid in the feeding tube, and then the hot water returns directly to the interior of the liquid storage tank through the reflux pipe.

For example, the hot water in the sleeve of the above-mentioned equipment can preheat the liquid in the feeding tube, and then the hot water returns directly to the interior of the liquid storage tank through the reflux pipe. However, the used water may contain impurities such as organic matter and inorganic salts. Then, when it returns to the water tank directly without treatment, they will accumulate in the water tank, causing the water quality to gradually deteriorate, and then produce odor and even harmful substances, thereby reducing the practicality of the equipment.

[0047] Please refer to Figures 1-5 , the present utility model provides a technical solution: a double rectification device for trifluoromethylthiotrifluorotoluene, including a connection box 1;

[0048] A filtering device is provided on the connection box 1;

[0049] The filtering device includes a filtering tank 7, a cooler 9 and a water tank 8. A return pipe 10 is fixedly connected to the lower end of the cooler 9. One end of the return pipe 10 away from the cooler 9 is fixedly connected to a connection box 1. The upper end of the cooler 9 is fixedly connected to one end of the filtering tank 7 through a hose. A sliding seat groove 13 is formed on the outer surface of the filtering tank 7. The sliding seat groove 13 is in an "arc" shape. The filtering tank 7 is fixedly connected to the upper end of the water tank 8 through a hose. A sliding seat 12 is slidably connected inside the sliding seat groove 13. A push block groove 16 is formed on the outer surface of the sliding seat 12. Two push blocks 14 are slidably connected inside the push block groove 16. Two limit blocks 6 are slidably connected inside the sliding seat 12. Two limit block grooves 17 are formed inside the sliding seat groove 13. One ends of the two limit blocks 6 close to the limit block grooves 17 are respectively in contact with the inner walls of the corresponding limit block grooves 17. One ends of the two push blocks 14 close to the limit blocks 6 are respectively fixedly connected to the outer walls of the corresponding limit blocks 6. A return spring 15 is arranged inside the push block groove 16. Two ends of the return spring 15 are respectively fixedly connected to one end of the corresponding push block 14. A filter plate 18 is fixedly connected to the inner wall of the sliding seat 12.

[0050] Wherein, a primary rectification cylinder 3 is arranged outside the connection box 1. The upper end of the primary rectification cylinder 3 is fixedly connected to a secondary rectification cylinder 4 through a fixed sleeve. One end of the connection box 1 away from the water tank 8 is fixedly connected to a feed pipe 2. The feed pipe 2 passes through the connection box 1 through a hose and is fixedly connected to the primary rectification cylinder 3. The inside of the primary rectification cylinder 3 is connected to the inside of the secondary rectification cylinder 4 through a connection block. The upper end of the secondary rectification cylinder 4 is fixedly connected to a collection cylinder 5 through a fixed sleeve. The inside of the collection cylinder 5 is connected to the inside of the secondary rectification cylinder 4 through a connection block. The water tank 8 enters the inside of the collection cylinder 5 and the secondary rectification cylinder 4 through hoses respectively, spirals four times inside and extends outside the collection cylinder 5 and the secondary rectification cylinder 4 and is fixedly connected to the connection box 1. A heating block 11 is installed inside the lower end of the secondary rectification cylinder 4. A heating block 11 of the same kind is installed inside the lower end of the primary rectification cylinder 3.

[0051] Further, when using this device, it is started by connecting to an external power supply. First, connect the feed pipe 2 to an external device, and then the external device transports raw materials into the primary rectification cylinder 3 through the feed pipe 2. Then start the heating block 11 to heat the raw materials inside the primary rectification cylinder 3. Then the steam inside the primary rectification cylinder 3 enters the inside of the secondary rectification cylinder 4 through the connection block. Then the water tank 8 transports water through a hose. When the water passes through the hose from the inside of the secondary rectification cylinder 4, the condensation of the steam is accelerated. Then the steam generated by the heating block 11 inside the secondary rectification cylinder 4 enters the inside of the collection cylinder 5, and then the water accelerates its condensation.

[0052] Furthermore, when water flows into the interior of the connection box 1 and then returns to the interior of the water tank 8 through the return pipe 10, it is cooled by the cooler 9 and then processed by the filter plate 18 inside the filter tank 7. When it is necessary to remove the filter plate 18, pushing the push block 14 to move in the opposite direction drives the return spring 15 to contract and at the same time drives the limit block 6 to move in the opposite direction. Then, due to the opposite movement of the limit block 6, the other end of it disengages from the interior of the limit block groove 17, and then the sliding seat 12 and the filter plate 18 can be taken out from the interior of the filter tank 7.

[0053] When water in the filtering device flows into the interior of the connection box 1 and then returns to the interior of the water tank 8 through the return pipe 10, it is cooled by the cooler 9 and then processed by the filter plate 18 inside the filter tank 7. This can effectively treat impurities such as organic matter and inorganic salts contained in the used water, avoid the gradual deterioration of water quality, and at the same time greatly improve the practicality of the equipment. By pushing the push block 14 to move in the opposite direction, the return spring 15 is driven to contract and at the same time the limit block 6 is driven to move in the opposite direction. Then, due to the opposite movement of the limit block 6, the other end of it disengages from the interior of the limit block groove 17, and then the sliding seat 12 and the filter plate 18 can be taken out from the interior of the filter tank 7. This facilitates the staff to remove the filter plate 18, avoids the need for the staff to use tools to remove it, effectively improves the work efficiency of the staff, and at the same time reduces the workload of the staff.

[0054] Working principle: First, connect the feed pipe 2 to an external device, and then the external device transports raw materials into the interior of the primary rectification cylinder 3 through the feed pipe 2. Then, start the heating block 11 to heat the raw materials inside the primary rectification cylinder 3. Then, the steam inside the primary rectification cylinder 3 enters the interior of the secondary rectification cylinder 4 through the connecting block. Then, the water tank 8 transports water through a hose. When the water passes through the interior of the secondary rectification cylinder 4 through the hose, the condensation of the steam is accelerated. Then, the steam generated by the heating block 11 inside the secondary rectification cylinder 4 enters the interior of the collection cylinder 5, and then it is accelerated to condense by the water. After that, the water flows into the interior of the connection box 1 and then returns to the interior of the water tank 8 through the return pipe 10. It is cooled by the cooler 9 and then processed by the filter plate 18 inside the filter tank 7. When it is necessary to remove the filter plate 18, pushing the push block 14 to move in the opposite direction drives the return spring 15 to contract and at the same time drives the limit block 6 to move in the opposite direction. Then, due to the opposite movement of the limit block 6, the other end of it disengages from the interior of the limit block groove 17, and then the sliding seat 12 and the filter plate 18 can be taken out from the interior of the filter tank 7.

[0055] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
