Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a chemical reactor heated by a water bath. Background Art

[0002] A water bath reactor is a device used for chemical reactions. Its main feature is that the reaction medium is heated or cooled by a water bath to control the reaction temperature. Water bath reactors are widely used in the fields of chemistry, pharmaceuticals, food processing, etc., and are especially suitable for reaction processes that require precise temperature control.

[0003] The utility model patent application number CN201720307555.X discloses an efficient water bath heating reactor. The reactor is designed with an auxiliary heating tube in the water bath interlayer, which is convenient for heating the water inside the reactor interlayer when the water temperature is detected to be insufficient, so as to ensure the temperature required for the reaction in the reactor.

[0004] However, in actual applications, scale will form on the surface of the heating tube and the inner wall of the water bath interlayer when the heating tube is heated, which affects heat transfer and is difficult to clean, and needs to be improved. Utility Model Content

[0005] The technical problem to be solved by the utility model is that scale is formed on the surface of the heating tube of the existing water bath heating reactor and the inner wall of the water bath interlayer, which affects heat transfer and is inconvenient to clean.

[0006] In order to solve the above problems, the technical solution of the present invention is: a water bath heated chemical reactor, comprising a reactor body, a feed port is provided at the top of the reactor body, a discharge pipe is provided at the bottom, a protective shell is provided on the outer side of the lower part, a water storage chamber is formed between the protective shell and the reactor body, a drain pipe is provided on the upper part of the side of the water storage chamber, and a water inlet pipe is provided on the bottom. A heating box is provided on one side of the reactor body, an inner barrel and an electric heating pipe for heating the inner barrel are installed inside the heating box, and a water outlet pipe and a return pipe are connected to the lower and upper parts of the side of the inner barrel respectively. A filter assembly is provided on one side of the heating box, and a circulating pump is provided between the water inlet end of the filter assembly and the heating box, the water outlet end of the filter assembly is connected to the water inlet pipe, and the drain pipe is connected to the return pipe.

[0007] Furthermore, a sealing cover is installed at the feed inlet, a solenoid valve is installed on the discharge pipe, a pressure relief valve is provided on the top of the kettle body, and a temperature and pressure sensor is installed on the inner top.

[0008] Furthermore, a motor is installed on the top of the kettle body, an output end of the motor is connected to a stirring shaft that passes through the top surface of the kettle body, and a stirring paddle is installed at the bottom of the stirring shaft.

[0009] Furthermore, a barrel cover is detachably mounted on the top of the inner barrel.

[0010] Furthermore, the filter assembly includes a shell, a top cover is threadedly connected to the top of the shell, an output pipe is connected to the lower side, a through hole is opened in the middle of the top cover, and a cylinder is fixed to the top outside the through hole, an input pipe is fixed to the side of the cylinder, and a filter cartridge is detachably installed on the bottom of the top cover.

[0011] Furthermore, an annular mounting seat is fixedly connected to the bottom of the top cover outside the through hole, and the filter cartridge is threadedly mounted on the mounting seat.

[0012] The advantages of this invention over existing technologies are that it heats cold water in the inner barrel, and a circulating pump delivers hot water to the cylinder, where it is filtered by the filter cartridge and then delivered to the water storage chamber. This prevents scale from entering and accumulating inside the water storage chamber, and does not affect heat transfer. By placing the heating element externally and filtering the hot water entering the water storage chamber, this invention avoids affecting heat transfer and eliminates the need to clean scale from the water storage chamber, making it more practical.
