Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. When cimetidine is refined, a reactor is often used for preparation.
[0003] Currently, when refining cimetidine, activated carbon is needed to adsorb impurities. When filtering the cimetidine solution, the activated carbon may be blocked inside the mesh of the filter, causing the filter to filter the solution more slowly, which in turn causes the filtration time to increase, thus causing an impact.

[0004] The utility model aims to solve the shortcomings in the prior art and provides a cimetidine reaction kettle.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a reactor and a motor arranged on the top of the reactor, a filter screen is arranged in the reactor, and a stirring rod is fixed on the surface of the rotating shaft of the motor, including: an ejection device, including a top plate arranged in the reactor for axial movement, and an ejector pin arranged on the top plate and matched with the filter holes of the filter screen in the reactor; a blowing device, including a heating pump, a connecting pipe arranged at the output end of the heating pump, and an air ring fixedly connected to the other end of the connecting pipe, the air ring is sleeved on the surface of the stirring rod of the motor, the rotating shaft of the motor and the inside of the stirring rod are both provided with grooves, and the surface of the stirring rod is provided with blowing holes.
[0006] The effect achieved by the above-mentioned components is: under the action of the ejection device, the blocked mesh holes of the filter can push out the impurities inside the mesh holes through the ejector plate and the ejector pin, thereby achieving the ejection effect. When it is necessary to purify cimetidine, the activated carbon, anhydrous ethanol and crude cimetidine are put into the reactor, and the motor drives the rotating shaft and the stirring rod to rotate, so that under the action of the activated carbon, the impurities inside the cimetidine are adsorbed and separated by the activated carbon, and the valve is opened to let the solution flow out. Under the action of the filter, the activated carbon is retained in the reactor, thereby achieving the effect of preparing refined cimetidine.

[0009] Preferably, a first spring is sleeved on the surface of the sliding rod, and two ends of the first spring are fixedly connected to the bottom of the reactor at one end of the sliding rod away from the bottom of the reactor.

[0015] Preferably, a second spring is sleeved on the surface of the clamping rod, and two ends of the second spring are respectively fixedly connected to the surface of the reactor and an end of the clamping rod away from the surface of the reactor.
[0016] The effects achieved by the above components are as follows: under the action of the second spring, the clamping rod is inserted into the interior of the slider in a self-locking manner, thereby achieving a fixing effect. When it is necessary to eject the activated carbon inside the mesh of the filter, the clamping rod is pulled outward, thereby separating the clamping rod from the slider, and then under the action of the first spring, the ejector plate pushes the ejector pin upward and is inserted into the mesh to open the discharge port, so that the activated carbon can be pulled out.
