The heat-conducting stirring rods 10 are made of metal materials with good thermal conductivity. The length of the heat-conducting stirring rods 10 is less than the inner diameter of the reactor 1, so that the heat-conducting stirring rods 10 can rotate smoothly. A feeding pipe 11 is fixedly installed on the top side of the cover plate 2. Various raw materials required for the production of acid cleaning agents are easily added to the interior of the reactor 1 through the feeding pipe 11. A second heating rod 12 is fixedly installed on the reactor 1. The bottom end of the reactor 1 is fixedly connected to a three-way valve 13 through a pipeline. One of the connections of the three-way valve 13 is fixedly connected to the reactor 1. A discharge pipe 14 is fixedly connected to the interface, and a first control valve 15 is provided on the discharge pipe 14. When the acid cleaning agent is produced, the first control valve 15 is in a closed state, which can prevent the material from being discharged from the discharge pipe 14. A water inlet hole 16 is provided on the outer surface of the rotating shaft 9. When the acid cleaning agent is prepared, the second heating rod 12 and the first heating rod 4 are started. With the start of the second heating rod 12, the raw materials around the inner wall of the reactor 1 are heated. With the start of the first heating rod 4, the water inside the water tank 3 can be heated, and the water between the rotating shaft 9 and the heat-conducting stirring rod 4 is heated through the water inlet hole 16.

[0029] 2) Activating the second heating rod 12 and the first heating rod 4. The second heating rod 12 heats the raw materials around the inner wall of the reactor 1. The first heating rod 4 heats the water inside the water tank 3 and heats the water inside the rotating shaft 9 and the heat-conducting stirring rod 10 through the water inlet 16, thereby increasing the temperature of the heat-conducting stirring rod 10.

[0030] 3) Starting the motor 6, and under the transmission action of the first bevel gear 7 and the second bevel gear 8, the rotating shaft 9 drives the heat-conducting stirring rod 10 to rotate. As the heat-conducting stirring rod 10 rotates, it stirs and heats the raw materials for producing the acid cleaning agent inside the reactor 1, thereby uniformly and quickly increasing the temperature inside the reactor 1 and increasing the dissolution rate of the raw materials for producing the acid cleaning agent. During this process, the second control valve 20 is opened and the delivery pump 18 is started. At this time, the material precipitated at the bottom of the reactor 1 will be re-delivered to the interior of the reactor 1 through the tee pipe 13, the return pipe 17 and the return pipe 19 to react;

[0031] 4) After the acidic cleaning agent is prepared, the first control valve 15 is opened and the second control valve 20 is closed, and the material is discharged from the discharge pipe 14.

Through the coordinated arrangement of the three-way valve 13, the return pipe 17, the delivery pump 18 and the return pipe 19, the raw materials precipitated at the bottom of the reactor 1 can be re-transported to the interior of the reactor 1 for reaction during the preparation process, so that the raw materials can participate in the reaction more completely, thereby making the effect of preparing the acidic cleaning agent better.
