Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of reaction kettle water circulation, specifically to a reaction kettle jacket circulating water system for praziquantel intermediate. BACKGROUND

[0002] Praziquantel is an organic compound with the chemical formula C19H24N2O2, which is a deworming drug for humans and animals, and is used to treat tapeworms and flukes. It is particularly effective against schistosoma, Chinese liver fluke, and broad-joint diphyllobothrium. During production, a reaction kettle is required.

[0003] Because reaction heat dissipation will affect the continuation of the reaction and the efficiency of the reaction to some extent, it is necessary to cool the reaction kettle. A jacket circulating water system is usually used. Cold water enters the jacket of the reaction kettle through the circulating system, absorbs heat in the reaction kettle, and is then discharged.

[0004] However, the water temperature after heat absorption is high, and it cannot be recycled. It can only be used for heating or directly discharged, causing waste of water resources.

[0005] Therefore, it is necessary to provide a water circulation system that can quickly cool the water body after heat absorption and recycle it. SUMMARY

[0006] The utility model aims at providing a reaction kettle jacket circulating water system for praziquantel intermediate to at least partially solve the above technical problems and quickly cool and recycle the water body.

A stirring mechanism is rotatably connected to the bottom of the driving motor and arranged inside the heat dissipation cylinder. A support plate is fixedly installed on one side of the heat dissipation cylinder on the top of the cooling barrel. An air guide pipe is obliquely installed on the support plate and faces the heat dissipation cylinder. A blower is fixedly installed on the other end of the air guide pipe and arranged on the support plate.

[0009] The input unit includes a storage barrel, an internal part of the storage barrel is provided with a water pump, a water pumping end of the water pump is provided with a water pumping pipe penetrating through the cooling barrel and being in the liquid collecting barrel, a conveying pipe is arranged at an end of the water pump away from the water pumping pipe, an input pipe is fixedly installed on a side of the kettle body away from the discharge pipe, and a liquid inlet pipe connected with the conveying pipe is fixedly connected in the input pipe.

[0010] Preferably, the flow guide pipe is transparent, a bottom end of the flow guide pipe is directed to the baffle at the top of the heat dissipation cylinder, and the flow guide pipe uniformly conveys water.

[0011] Preferably, the air guide pipe is a through hole, and the air guide pipe is directed to the inside of the driving motor and the heat dissipation cylinder.

[0012] Preferably, the stirring mechanism has a plurality of fan blades, and the fan blades of the stirring mechanism are not in contact with the inner wall of the heat dissipation cylinder.

[0013] Preferably, the discharge port is directly above the liquid collecting barrel, the liquid collecting barrel is not in contact with the inner wall of the cooling barrel, and a faucet is arranged at the bottom of the cooling barrel.

[0014] Preferably, the height of the discharge pipe on the kettle body is lower than that of the input pipe, and control valves are arranged on the discharge pipe and the input pipe.

[0015] Compared with the prior art, the utility model has the advantages that:

[0016] When the utility model is used, the cold water heat absorption cylinder in the reaction kettle jacket discharges hot water into the heat dissipation cylinder through the output unit, the hair dryer blows air to the driving motor and the heat dissipation cylinder to scatter hot air, meanwhile, the driving motor drives the stirring mechanism to stir the hot water in the heat dissipation cylinder to accelerate heat dissipation, due to the arrangement of the discharge port, the hot water moves downward at a relatively high speed and falls into the liquid collecting barrel, ice blocks are put between the cooling barrel and the liquid collecting barrel to accelerate cooling of the liquid collecting barrel, meanwhile, water vapor is discharged from the top of the liquid collecting barrel and the cooling barrel, when the ice blocks in the cooling barrel are melted into water and the temperature rises, the water is discharged through the faucet at the bottom of the cooling barrel for subsequent freezing into ice blocks, and the ice blocks are put again for cooling, and the operation is repeated for multiple times, so that the hot water in the liquid collecting barrel can be cooled sufficiently, and the water cooled by the water pump is separated and input into the reaction kettle through the input unit, so that the water after heat absorption can be cooled and reused quickly and conveniently, and the waste of water resources is effectively reduced.
