Description

Technical Field

[0001] This utility model relates to the field of recycling equipment technology, and in particular to a distillation apparatus for recycling butanol. Background Technology

[0002] Butanol, also known as n-butanol, is an organic compound, a colorless and transparent liquid, slightly soluble in water, and soluble in most organic solvents such as ethanol and ether. It is mainly used in the preparation of esters, plasticizers, pharmaceuticals, and paints. It can also be used as a solvent. Recycling butanol can not only save money but also reduce its pollution to the environment and organisms, which has important economic and environmental significance.

[0003] Announcement No. CN219050329U discloses a device for recovering butanol. This device involves injecting coolant into a cooling tank, with the blower's output pipe passing through the tank. The low-temperature liquid inside the cooling tank liquefies the n-butanol vapor inside the collection pipe, causing the liquefied n-butanol to flow into the butanol collection tank. This facilitates cooling the hot gas inside the output pipe. Simultaneously, the cooling tank is installed outside the recovery tank to reduce the external temperature. This method facilitates the conversion of heat inside the output pipe, thereby improving energy utilization.

[0004] However, during the implementation of this device, the recovered n-butanol solution contains a large number of particles and impurities. The device directly pours the recovered solution into the equipment for distillation, resulting in a large number of impurities remaining inside the equipment. This requires subsequent cleaning by staff to remove the impurities, increasing the workload of the staff. Therefore, a distillation device for recovering butanol is proposed to solve the above problems. Utility Model Content

[0007] Preferably, the baffle has a sliding groove on the side near the inside of the recycling bin, a sliding block is slidably connected to the inner wall of the sliding groove, and a striking plate is fixedly connected to the surface of the sliding block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The butanol recovery distillation device, through the setting of the filter box, avoids the impurities in the butanol solution from entering the inside of the recovery box, and avoids the need for staff to clean the impurities remaining inside the recovery box.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a distillation device for recovering butanol, including a support plate 1, a recovery box 2 fixedly connected to the surface of the support plate 1, an inlet pipe 4 fixedly connected to the upper end of the recovery box 2, a baffle 5 slidably connected inside the recovery box 2, a filter box 7 fixedly connected to one side of the baffle 5 inside the recovery box 2, and the holes on the surface of the filter box 7 correspond to the inlet pipe 4, a threaded rod 6 rotatably connected inside the baffle 5, and the threaded rod 6 penetrates the interior of the filter box 7, a fixing plate 8 fixedly connected inside the recovery box 2, and a threaded groove 17 opened on the side of the fixing plate 8 near the filter box 7.

[0024] A sliding groove 13 is provided on the side of the baffle 5 near the inside of the recycling bin 2. The sliding groove 13 is T-shaped. A sliding block 14 is slidably connected to the inner wall of the sliding groove 13. A striking plate 15 is fixedly connected to the surface of the sliding block 14. The striking plate 15 is trapezoidal. The T-shaped arrangement of the sliding groove 13 limits and guides the sliding of the sliding block 14.

[0025] A reset spring 16 is fixedly connected inside the sliding groove 13. The end of the reset spring 16 away from the sliding groove 13 is fixedly connected to the sliding block 14. By setting the reset spring 16, the sliding of the sliding block 14 is controlled, thereby controlling the reset sliding of the striking plate 15.

[0026] A rubber pad is provided on the surface of the baffle 5, and the surface of the rubber pad is in contact with the inside of the recovery box 2. The rubber pad fills the gap between the baffle 5 and the recovery box 2, thereby reducing the leakage of vaporized solution during the distillation process.

[0027] The recycling tank 2 is equipped with a heating wire 10, which is connected to an external controller. The external controller controls the heating wire 10 to heat the solution inside the recycling tank 2, thereby performing distillation processing on the solution. This is described in the comparative case and will not be explained further.

[0028] A rotating rod 9 is rotatably connected inside the recycling bin 2. A stirring rod 12 is fixedly connected to the surface of the rotating rod 9. A drive rod 11 is fixedly connected to the surface of the rotating rod 9. A motor 3 is fixedly connected to the upper end of the recycling bin 2. The output end of the motor 3 extends through the interior of the recycling bin 2 and is rotatably connected to the interior of the recycling bin 2. The output end of the motor 3 is fixedly connected to the rotating rod 9 through a coupling.

[0029] Working principle: When butanol solution needs to be distilled, the butanol solution is poured into the recovery tank 2 through the inlet pipe 4, and then enters the filter tank 7. The filter tank 7 filters the incoming butanol solution, thereby trapping impurities in the butanol solution. Only the butanol solution filtered by the filter tank 7 enters the recovery tank 2 for distillation. When the filter tank 7 needs to be removed, the threaded rod 6 is rotated, and the threaded rod 6 rotates and separates from the threaded groove 17 on the fixing plate 8, thus no longer fixing the filter tank 7. Then the threaded rod 6 is pulled, causing the threaded rod 6 to drive the baffle 5 and the filter tank 7 out of the recovery tank 2, so that the filter tank 7 can be cleaned separately.

[0030] When the butanol solution is poured into the recovery tank 2, the motor 3 is started simultaneously. The output of the motor 3 drives the rotating rod 9 to rotate, which in turn drives the stirring rod 12 to mix the butanol solution. At the same time, the rotating rod 9 drives the drive rod 11 to rotate. As the drive rod 11 rotates, it contacts the inclined surface of the striking plate 15. The striking plate 15 is then subjected to force, causing the sliding block 14 to move. The movement of the sliding block 14 causes the return spring 16 to deform. When the drive rod 11 separates from the striking plate 15, the spring force of the return spring 16 causes the striking plate 15 to be subjected to force, causing the sliding block 14 to move upward and collide with the bottom of the filter box 7. This causes the filter box 7 to vibrate, shaking off the impurities inside the filter box 7, reducing the possibility of clogging, and allowing the butanol solution to be filtered smoothly, further improving the effectiveness of the device.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
