[0007] To achieve the above-mentioned purpose, the utility model proposes a methyl acetate distillation device, comprising a tank body, wherein both ends of the tank body are fixedly connected to a hot gas conveying device and a motor, respectively, a stirring shaft is arranged inside the tank body, both ends of the stirring shaft pass through the ends of the tank body, one end of the stirring shaft is fixedly connected to the motor, and the other end of the stirring shaft is rotatably connected to the hot gas conveying device, the stirring shaft is hollow, and an auxiliary component is arranged inside the stirring shaft, wherein:

When the heating system of the device fails, the temperature in the tank body decreases, and the pressure in the tank body also decreases synchronously. At this time, the air pressure plate loses the effect of pressure pressure, and the air pressure plate moves in the direction away from the stirring shaft under the action of the first spring elastic force.

Due to the mutual engagement of the first small clamping tooth and the second small clamping tooth, the push plate will drive the driven plate to move. Driven by the movement of the driven plate, the baffle rotates with the rotating shaft as the axis point. At this time, the hot air in the hot air conveying device will enter the stirring shaft and then be discharged through the nozzle, thereby achieving the effect of heating the tank body. When the temperature in the tank body rises, the pressure in the tank body will also increase, and the air pressure plate will be pushed downward under the action of pressure. At this time, the baffle blocks the stirring shaft again under the action of the second spring thrust, and the heat cannot be transmitted to the tank body through the stirring shaft.

[0018] The advantage of this design is that when the device is performing distillation and the heating system fails, the auxiliary components can promptly transport hot gas into the tank according to the pressure inside the tank, thereby achieving the heating effect. When the temperature inside the tank returns to normal, the auxiliary components can automatically shut down, and this process does not require staff operation, which provides great convenience, reduces the workload of staff, improves the efficiency and quality of distillation, and reduces losses caused by heating system failures.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-3 As shown, a methyl acetate distillation device includes a tank body 1, two ends of the tank body 1 are fixedly connected with a hot air conveying device 3 and a motor 4, the top of the tank body 1 is fixedly connected with a feed port 101, and the bottom of the tank body 1 is fixedly connected with a discharge port 102.

[0025] Both ends of the tank body 1 are fixedly connected with protective end heads 2 , and the hot air conveying device 3 and the motor 4 are both arranged inside the protective end heads 2 .

[0026] A stirring shaft 5 is arranged inside the tank body 1. Both ends of the stirring shaft 5 pass through the ends of the tank body 1. One end of the stirring shaft 5 is fixedly connected to the motor 4, and the other end of the stirring shaft 5 is rotatably connected to the hot air conveying device 3. The stirring shaft 5 is hollow.

[0027] Two pairs of protective clips 103 are provided on the side wall of the tank body 1, and the side walls of the two pairs of protective clips 103 are fixedly connected with connecting rods 104, and the side walls of the two pairs of protective clips 103 are fixedly connected with supporting rods 105. Both ends of the supporting rods 105 are fixedly connected with vertical rods 106, and the side walls of the vertical rods 106 are fixedly connected with anti-shake short rods 107.

[0028] An auxiliary component 6 is provided inside the stirring shaft 5, and the auxiliary component 6 includes an outer shell 61, which is slidably connected to the side wall of the stirring shaft 5. A balancing air pressure hole 63 is opened on the top of the outer shell 61, and an air pressure plate 64 is slidably connected inside the outer shell 61. Since the pressure and temperature in the tank body 1 are proportional, the pressure is high when the temperature is high. When the heating system of the device fails, the temperature in the tank body 1 decreases, and the pressure in the tank body 1 also decreases synchronously. At this time, the air pressure plate 64 loses its pressure pressure function.

[0029] The bottom of the air pressure plate 64 is fixedly connected with a driving rod 65, and the bottom of the driving rod 65 passes through the side wall of the stirring shaft 5 and extends into the inside thereof. A first spring 66 is arranged inside the housing 61. The air pressure plate 64 moves in a direction away from the stirring shaft 5 under the action of the elastic force of the first spring 66. The first spring 66 is sleeved on the side wall of the driving rod 65. The two ends of the first spring 66 are respectively fixedly connected to the air pressure plate 64 and the stirring shaft 5. One end of the driving rod 65 extending into the stirring shaft 5 is fixedly connected with a push plate 67. The air pressure plate 64 drives the push plate 67 through the driving rod 65. The plate 67 moves, and a baffle 68 is arranged inside the stirring shaft 5. The end of the baffle 68 is fixedly connected to the rotating shaft 69, and the side wall of the rotating shaft 69 is rotatably connected to the inner wall of the stirring shaft 5. The side of the baffle 68 close to the driving rod 65 is fixedly connected to the driven plate 610, and the side of the driven plate 610 close to the outer shell 61 is engraved with a second small tooth 611, and the side of the push plate 67 close to the outer shell 61 is engraved with a first small tooth 671. The first small tooth 671 is arranged at one end of the push plate 67 close to the baffle 68, and a second spring 612 is arranged inside the stirring shaft 5.

[0030] Due to the mutual engagement of the first small latch tooth 671 and the second small latch tooth 611, the push plate 67 will drive the driven plate 610 to move. Driven by the movement of the driven plate 610, the baffle plate 68 rotates with the rotating shaft 69 as the axis point. At this time, the hot air in the hot air conveying device 3 will enter the stirring shaft 5, and then be discharged through the nozzle 52, so as to achieve the effect of heating the tank body 1. When the temperature in the tank body 1 increases, the pressure in the tank body 1 will also increase, and the air pressure plate 64 will be pushed downward under the action of the pressure. At this time, the baffle plate 68 will block the stirring shaft 5 again under the action of the thrust of the second spring 612. At this time, the heat cannot be transmitted to the tank body 1 through the stirring shaft 5. The two ends of the second spring 612 are respectively fixedly connected to the driven plate 610 and the stirring shaft 5.

[0031] When the device is performing distillation and the heating system fails, the auxiliary component 6 can timely transport hot gas into the tank body 1 according to the pressure in the tank body 1, thereby achieving the heating effect. When the temperature in the tank body 1 returns to normal, the auxiliary component 6 can automatically shut down, and this process does not require staff to operate, which provides great convenience, reduces the workload of staff, improves the efficiency and quality of distillation, and reduces the losses caused by heating system failures.

[0032] The stirring shaft 5 is arranged on the side wall of the tank body 1 and is fixedly connected to a plurality of stirring rods 51 , and the ends of the stirring rods 51 are fixedly connected to the spray heads 52 .

[0033] The stirring shaft 5 is arranged on the side wall inside the tank body 1 and is fixedly connected to a connecting short rod 7. When the stirring shaft 5 rotates, the connecting short rod 7 will be driven to move together. One end of the connecting short rod 7 close to the inner wall of the tank body 1 is fixedly connected to a cleaning rod 71. The cleaning rod 71 will rotate around the inner wall of the tank body 1 under the drive of the connecting short rod 7, so as to achieve the effect of cleaning the inner wall of the tank body 1 and avoid residual materials on the inner wall of the tank body 1, thereby affecting the next distillation. The cleaning rod 71 is arranged on the inner wall of the tank body 1, and a track 72 is opened on the inner wall of the tank body 1. One end of the cleaning rod 71 is fixedly connected to the connecting short rod 7, and the other end of the cleaning rod 71 is slidably connected in the track 72.

[0034] A barrier net 62 is fixedly connected to the top of the housing 61 , and the barrier net 62 is arranged above the balanced air pressure hole 63 .

[0035] Working principle: When the device is working, since the pressure and temperature in the tank body 1 are proportional, when the temperature is high, the pressure is high. When the heating system of the device fails, the temperature in the tank body 1 decreases, and the pressure in the tank body 1 also decreases synchronously. At this time, the air pressure plate 64 loses the effect of pressure pressure. The air pressure plate 64 moves away from the stirring shaft 5 under the action of the elastic force of the first spring 66. The air pressure plate 64 drives the push plate 67 to move through the driving rod 65. Due to the mutual engagement of the first small latch tooth 671 and the second small latch tooth 611, the push plate 67 will move. The driven plate 610 moves, and the baffle 68 rotates around the rotating shaft 69 under the drive of the driven plate 610. At this time, the hot air in the hot air conveying device 3 will enter the stirring shaft 5, and then be discharged through the nozzle 52, so as to achieve the effect of heating the tank body 1. When the temperature in the tank body 1 increases, the pressure in the tank body 1 will also increase, and the air pressure plate 64 will be pushed downward under the action of the pressure. At this time, the baffle 68 blocks the stirring shaft 5 again under the action of the thrust of the second spring 612, and the heat cannot be transmitted to the tank body 1 through the stirring shaft 5.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
