Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a chemical reaction kettle with a cleaning function. Background Art

[0002] Chemical reactor is one of the indispensable and important equipment in chemical production. It has a wide range of applications and plays an important role. During use, it is necessary to select appropriate materials and structures according to the specific usage and working environment to ensure the safe, efficient and stable operation of the reactor.

[0003] Chemical reactors are generally used for the preparation and treatment of chemical solutions. Acidic or alkaline solutions often remain inside them. If they are not neutralized and cleaned in time, it will easily affect the subsequent preparation of chemical solutions in the reactor. Common chemical reactors do not have the function of neutralizing and cleaning acidic or alkaline solutions. Therefore, chemical reactors with cleaning functions are needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a high-speed pretreatment water treatment equipment to solve the problem raised in the above background technology: there is often residual acidic or alkaline solution inside the chemical reactor, which, if not neutralized and cleaned in time, will easily affect the preparation of subsequent chemical solutions in the reactor, and common chemical reactors do not have the function of neutralizing and cleaning acidic or alkaline solutions.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a chemical reactor with a cleaning function, comprising a thermal insulation jacket, a reaction inner tube inserted into the interior of the thermal insulation jacket, a cooling assembly fixedly connected to the outer wall of the reaction inner tube, a closed top cover threadedly connected to the top of the thermal insulation jacket, a stirring assembly installed at the center of the closed top cover, the stirring end of the stirring assembly extending to the interior of the reaction inner tube, a discharge cone pipe connected to the bottom flange of the reaction inner tube, the discharge cone pipe extending to the outside of the thermal insulation jacket, fixed legs fixedly connected to both sides of the lower surface of the thermal insulation jacket, a pH detector installed on one side of the upper surface of the closed top cover, the detection end of the pH detector extending to the interior of the reaction inner tube, and two feed ducts fixedly arranged at the edge of the upper surface of the closed top cover.

[0006] Preferably, the cooling assembly comprises a cooling conduit, and a top of one side of the cooling conduit is fixedly connected to a liquid inlet conduit.

[0007] Preferably, the bottom of one side of the cooling conduit is fixedly connected to a liquid outlet conduit, and the top of one side of the insulation jacket is fixedly installed with a solenoid valve.

[0008] Preferably, a temperature sensor is fixedly mounted on the bottom of the outer side of the reaction inner cylinder, and a detection end of the temperature sensor is in contact with the reaction inner cylinder.

[0009] Preferably, the liquid outlet end of the solenoid valve is connected to the liquid inlet conduit flange.

[0010] Preferably, the stirring assembly comprises a reduction motor, the output end of the reduction motor is drivingly connected to a stirring guide rod, and one end of the stirring guide rod is fixedly connected to a U-shaped blade.

[0011] Technical effects and advantages of the utility model:

[0012] (1) The device detects the pH value of the solution inside the reaction cylinder by means of a pH detector, and can add an appropriate amount of neutralizing alkaline or acidic solution into the feed conduit to neutralize the solution in the reaction cylinder. The stirring guide rod and the U-shaped blade can be driven by the reduction motor to rotate, so that the solution inside the reaction cylinder is evenly mixed and the neutralization reaction rate is improved. Since a large amount of heat is released during the acid-base neutralization reaction, it may cause damage to the reaction cylinder and the insulation jacket. Therefore, when the temperature is too high, the temperature sensor opens the solenoid valve, and the condensed water source is connected to the solenoid valve and transported to the cooling conduit through the liquid inlet conduit to cool the reaction cylinder by heat exchange. The liquid after heat exchange can be discharged through the liquid outlet conduit for reuse, thereby solving the problem that the acidic or alkaline solution often remains inside the chemical reactor. If it is not neutralized and cleaned in time, it is easy to affect the preparation of the subsequent chemical solution in the reactor, and the common chemical reactor does not have the function of neutralizing and cleaning the acidic or alkaline solution.

[0013] (2) The device can detect the pH value of the solution inside the reaction cylinder after the reaction by means of a pH detector. When the pH value of the solution inside the reaction cylinder is within the error range, the solution inside the reaction cylinder can be discharged through the discharge cone to complete the cleaning.
