The motor is fixed at the middle position of the top end of the reaction kettle. A rotating shaft is arranged at the middle position inside the reaction kettle. Stirring rods are evenly fixed on the outer side of the rotating shaft. One end of each stirring rod is fixed with a fixing plate. A cleaning brush is arranged on one side of the fixing plate. Stirring paddles are fixed on both sides of the bottom end of the rotating shaft.

[0011] Preferably, the top end of the rotating shaft penetrates through the top end of the top cover and extends to the outside of the top cover and is fixedly connected to the output end of the motor. There are several groups of stirring rods, and the stirring rods are evenly distributed at equal intervals on the outer side of the rotating shaft. Both sides of the fixing plate are arc-shaped. One side of the cleaning brush abuts against the inner wall of the reaction kettle. The stirring paddle is arranged in an "L" shape.

[0012] Preferably, the sampling structure includes a sampling box, a liquid outlet, a connecting cylinder, a movable rod, a return spring, a return plate, a moving block, a piston, a filter screen, and a sampling tube. The sampling box is fixed on one side of the reaction kettle. A liquid outlet is arranged on one side of the sampling box close to the reaction kettle. A connecting cylinder is fixed on the side of the sampling box away from the reaction kettle. A movable rod is arranged inside the connecting cylinder. A return spring is arranged on the outer side of the movable rod. One end of the return spring on the outer side of the movable rod is provided with a return plate. One end of the movable rod is fixed with a moving block, and the other end of the movable rod is fixed with a piston. A filter screen is arranged at one end of the liquid outlet.

[0013] Preferably, one end of the liquid outlet penetrates through one side of the reaction kettle and extends to the inside of the reaction kettle. The inside of the sampling box is communicated with the inside of the liquid outlet. There are three groups of liquid outlets, and the liquid outlets are evenly distributed at equal intervals on one side of the sampling box.

[0014] Preferably, the connecting cylinder corresponds to the liquid outlet one by one. The movable rod and the return plate form a telescopic structure through the return spring. One end of the movable rod penetrates through one side of the sampling box and extends to the inside of the liquid outlet and is fixedly connected to one end of the piston.

[0015] The advantages of a reaction kettle with a sampling structure provided by the present utility model are as follows:

[0016] By providing a cleaning structure, starting the motor drives the rotating shaft to rotate, and then the rotating shaft drives the stirring rods and the stirring paddles to stir the inside of the reaction kettle. At the same time, during the rotation of the stirring rods, the fixing plate is driven to make the cleaning brush clean the inside of the reaction kettle, preventing materials from adhering to the inner wall of the reaction kettle and being difficult to clean.

[0017] By setting a sampling structure, pulling the moving block drives the movable rod, which in turn drives the piston to move horizontally inside the liquid outlet. Due to the movement of the piston, the liquid inside the reaction kettle is pumped into the inside of the liquid outlet under the action of air pressure. When the piston moves out of the inside of the liquid outlet, the liquid falls into the inside of the sampling box and is sampled through the sampling tube. When the moving block is released, the movable rod is driven by the elastic force of the return spring, and then the piston is reset, preventing the liquid from flowing out of the inside of the liquid outlet when sampling is not required. By arranging three groups of liquid outlets on one side of the reaction kettle, it is convenient to sample liquids at different levels, thus facilitating the collection of samples, enabling frequent sampling, improving the collection efficiency, and filtering impurities in the liquid through the filter screen, improving the purity of the samples.
