Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, in particular to a sealing device for a distillation kettle. Background Art

[0002] The distillation kettle is a kettle used for distillation in chemical production. It is mainly designed to solve the problem that the existing distillation kettle needs to be intermittently inspected and cleaned when the material contains solids and high-boiling-point substances during the production process.

[0003] At present, the existing distillation kettle is provided with a sealing sleeve between the stirring shaft and its inner wall, so as to seal the gap between the two and prevent air leakage. However, when the stirring shaft rotates for a long time, the sealing sleeve will be worn, the thickness of the sealing sleeve will become thinner, and a gap will be generated between the sealing sleeve and the inner wall of the reactor, reducing the sealing performance. At the same time, due to thermal expansion and contraction, the sealing sleeve will shrink and generate a gap, which affects the sealing performance. The sealing performance is poor and is not conducive to use.

[0004] After searching Chinese patents: a chemical distillation kettle sealing device (announcement number: CN218306221U), including a distillation kettle body, a motor is arranged at the upper end of the interior of the distillation kettle body, a rotating rod is arranged at the lower end of the motor, the rotating rod is rotatably connected to the inner wall of the distillation kettle body, a stirring rod is fixedly connected to the outer surface of the lower end of the rotating rod, a sealing device is arranged at the rotating part of the distillation kettle body and the rotating rod, the sealing device includes an inner sealing sleeve, an outer sealing sleeve, a sealing ring and an annular groove, an inner sealing sleeve is arranged on the outer surface of the rotating rod, and an outer sealing sleeve is arranged inside the distillation kettle body. The chemical distillation kettle sealing device is provided with a sealing ring inside the sealing device, and the sealing ring has the function of increasing the sealing area and strengthening the sealing effect. A supporting device is also arranged in the inner sealing sleeve, and a supporting spring inside the supporting device has the function of always supporting and pushing the inner sealing sleeve outward, so that the inner sealing sleeve is always in contact with and fits with the outer sealing sleeve to seal the distillation kettle body.

[0005] Although the above patent improves the sealing effect by setting an outer sealing sleeve and an inner sealing sleeve so that the inner sealing sleeve is always in contact with the outer sealing sleeve, the device has the disadvantage that the stirring mechanism used in the device is too simple and the stirring rod can only stir in one direction, resulting in low stirring efficiency of the material.

[0006] Therefore, it is necessary to invent a distillation kettle sealing device to solve the above problems. Utility Model Content

[0012] Preferably, one end of the extrusion spring is connected to an outer sealing sleeve, and a sliding groove is provided inside the outer sealing sleeve.

[0013] Preferably, the bottom end of the rotating shaft is connected to a first bearing, and a fixing plate is installed at the bottom of the first bearing.

[0014] Preferably, one end of the driven shaft is connected to a second bearing, and a discharge port is provided at the bottom of the distillation kettle body.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting a stirring assembly, a driving motor, a rotating shaft, a first stirring rod, a driving gear, a driven gear, a driven shaft, and a second stirring rod, the driving motor is operated so that the driving motor drives the rotating shaft to rotate, the outer wall of the rotating shaft is fixedly connected with a driving gear and a plurality of first stirring rods, one side of the driving gear is connected with a driven gear, and the driven gear is meshed and connected with the driving gear, so that the driving gear drives the driven gear to rotate, the interior of the driven gear is fixedly connected with a driven shaft, and the outer wall of the driven shaft is fixedly connected with a plurality of second stirring rods, so that when the driven shaft rotates, it drives the plurality of second stirring rods to rotate, because the driving gear and the driven gear rotate in opposite directions, the first stirring rod and the second stirring rod rotate in opposite directions, thereby greatly improving the stirring efficiency of the material in the distillation kettle body;

The inside of the sliding groove is fixedly connected with an extrusion spring, and one end of the extrusion spring is fixedly connected with an inner sealing sleeve. There are two groups of inner sealing sleeves, and a rotating shaft is sandwiched between the two groups of inner sealing sleeves. When the two groups of extrusion springs are installed, the extrusion springs are already in a compressed state. In this way, when the rotating shaft rotates, the two groups of inner sealing sleeves squeeze the rotating shaft under the action of the extrusion springs, so that the gap between the rotating shaft and the two groups of inner sealing sleeves is very small, thereby achieving a sealing effect.
