[0002] Acetic anhydride is an important chemical raw material, widely used in medicine, pesticides, dyes and other fields. With the rapid development of the chemical industry, the market demand for acetic anhydride continues to grow, so continuous production of acetic anhydride has become a trend. Continuous production of acetic anhydride has many advantages, such as high production efficiency, low energy consumption, and low cost. At the same time, continuous production can also improve product quality and stability and reduce the impact on the environment. Therefore, many chemical companies are actively exploring and promoting the technology of continuous production of acetic anhydride.

[0003] In the production process of acetic anhydride, it is necessary to adopt distillation to rectify the residue of acetic anhydride, and evaporate the acetic anhydride to a distillation tower for recovery. When the existing acetic anhydride distillation tank is in use, when the distillation is excessive and the residue concentration is too high, the slag discharge speed of the distillation tank is too slow, and there is a lack of a mechanism for conveying the residue, which affects subsequent processing.

[0004] Therefore, it is necessary to provide a new continuous slag discharge tank that is easy to maintain to solve the above technical problems. Utility Model Content

[0006] The utility model provides a continuous slag discharge tank that is easy to maintain and comprises a base, a distillation tank is fixed on the base, a mounting shaft is movably arranged inside the distillation tank, a stirring motor is installed on the top of the distillation tank, and the output end of the stirring motor is connected to the mounting shaft through a coupling;

[0007] A plurality of stirring blades are installed on the installation shaft, an auger blade is installed at the bottom of the installation shaft, a material guide pipe is connected to the bottom of the distillation tank, a valve is arranged at the material guide pipe, and a conveying mechanism is arranged directly below the material guide pipe.

[0008] In a preferred embodiment, a vent is provided at the top of the distillation tank, and a feed pipe is provided on one side of the top of the distillation tank.

[0009] In a preferred embodiment, the conveying mechanism includes an inclined box, which is fixed to the base through legs. A conveying auger is movably arranged inside the inclined box. The bottom of the inclined box is located directly below the material guiding pipe, and a discharge pipe is communicated with the top of the inclined box.

[0010] In a preferred embodiment, a U-shaped baffle is fixed on the base. The U-shaped baffle is located directly below the discharge pipe, and a collection tank is placed on the base. The collection tank is located inside the U-shaped baffle.

[0011] In a preferred embodiment, a threaded ejector rod is penetrated through the U-shaped baffle. The threaded ejector rod is threadedly connected with the U-shaped baffle. A pressing plate is installed on the threaded ejector rod, and a crank is fixed to the other end of the threaded ejector rod.

[0012] In a preferred embodiment, a plurality of heat dissipation fins are fixed on the surface of the inclined box, and the heat dissipation fins are made of aluminum alloy material.

[0013] Advantages of the present utility model:

[0014] 1. When this slag discharge tank is in use, the acetic anhydride residue to be rectified can be introduced into the distillation tank through the material guiding pipe. The residue is heated by the distillation tank. At the same time, the stirring motor is started to drive the stirring blades to stir the residue, increasing the heating speed. The acetic anhydride vapor in the residue can be discharged from the exhaust port for collection;

[0015] After rectification is completed, the valve is opened, and the stirring motor is started to drive the auger blades on the installation shaft to rotate, which can greatly accelerate the speed of the residue entering from the material guiding pipe to the inclined box, and the structure is simple and convenient for later maintenance work;

[0016] 2. The conveying auger inside the inclined box conveys the residue to the discharge pipe, and finally falls into the collection tank for collection under the action of gravity. By setting the U-shaped baffle, it can prevent the staff from placing the collection tank off-center. By rotating the crank to drive the threaded ejector rod to rotate, the pressing plate can be moved towards the collection tank to achieve the effect of fixing the collection tank and increasing the stability of the collection tank during use.
