[0042] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0043] The first implementation method:

[0044] Figure 1-5It is shown that an environmentally friendly anti-rust film forming pretreatment device comprises a heat-insulating stirring tank 1, a plurality of pretreatment structures 2 are connected to the heat-insulating stirring tank 1, and the input end of each pretreatment structure 2 is connected to a raw material tank 3;

[0045] The pretreatment structure 2 includes a heat treatment tank 201, a heater is connected to the heat treatment tank 201, the heating temperature of the raw material in the heat treatment tank 201 is determined according to the heating time and the melting point of the raw material, the output end of the heat treatment tank 201 is connected to the insulation pipe 202, the output end of the insulation pipe 202 is connected to the heat stabilization tank 203, and an opening and closing valve is connected between the output end of the heat stabilization tank 203 and the heat preservation stirring tank 1;

[0046] A heat exchange tube 4 is connected between the multiple heat stabilizing tanks 203, a heat exchange plate is connected between the heat exchange tube 4 and the multiple heat stabilizing tanks 203, and a conduit is connected to the input end and the output end of the heat exchange tube 4;

[0047] A servo motor is installed on the heat preservation stirring tank, and a stirring structure is installed at the power output end of the servo motor. The stirring structure includes a rotating shaft 501, a plurality of stirring frames 502 are fixedly connected to the rotating shaft 501, a plurality of stirring rods 503 are fixedly connected to the stirring frames 502, a protective plate 504 is connected to the stirring rods 503, and an electric heating plate is installed in the protective plate 504;

[0048] Figure 6-7 It is shown that a pressure sensing belt is laid between the stirring rod 503 and the protective plate 504, and the pressure sensing belt includes a conductive film for connecting the stirring rod 503 and the protective plate 504. The conductive film is a base film with wires laid inside, and a plurality of evenly distributed pressure detection units are installed in the conductive film. The pressure detection units are thin film pressure sensors, and the pressure detection units communicate with the control signal through the wires in the base film. A heat insulation film is laid between the stirring rod 503 and the protective plate 504 and on the pressure sensing belt, and the heat insulation film covers the outer walls of the stirring rod 503 and the protective plate 504, and the heat insulation film is made of elastic material.

[0049] An electric heating plate is installed on the protective plate 504; a plurality of clamping columns matching the stirring rod 503 are installed on the protective plate 504; the clamping columns include a telescopic column, a fixed end of the telescopic column is fixedly connected to the stirring rod 503, a movable end of the telescopic column is connected to the protective plate 504, and an electromagnet and a permanent magnet are connected to the fixed end and the telescopic end respectively, a compression spring is connected between the electromagnet and the permanent magnet, and the electromagnet is connected to the controller through a wire in a conductive film.

[0050] This embodiment can control the electromagnet to work intermittently, so that the protective plate 504 and the stirring rod 503 repel each other intermittently, and then reset by compressing the spring to achieve vibration of the protective plate 504. At the same time, the electric heating plate in the protective plate 504 works to heat, thereby achieving heating of the area near the protective plate 504.

[0051] During the stirring process of this embodiment, the pressure sensing belts on the multiple stirring rods 503 are used to detect whether there is local coagulation in the mixed raw materials. During the detection, the stirring rods 503 rotate with the rotating shaft 501. During the rotation process, the pressure sensing belts on the multiple stirring rods 503 detect the pressure state of the protective plate 504. If the pressure detection value of any protective plate 504 is greater than the set value A, or it is identified that the difference between the pressure detection value of any protective plate 504 and the pressure detection value of other protective plates 504 is greater than the set value B, it is determined that the protective plate 504 is in contact with the coagulation.

The protective plate 504 suspends local heating and vibration for a certain period of time, and then performs pressure detection. If the pressure detection value is normal, the local heating and vibration are stopped, otherwise the local heating and vibration continue during the rotation process;

[0052] In this embodiment, it is easy to locally heat the agglomerates in the raw materials during the stirring process to ensure that the raw materials are stirred in a molten state.

[0053] The second implementation method:

[0054] It also includes a pretreatment control system, which includes a processor connected to the heat preservation stirring tank 1, and the processor is connected to a control module, a raw material management module, a monitoring module and an alarm module;

[0055] The pretreatment structure 2, the raw material tank 3, the heat exchange tube 4 and the stirring structure 5 are all connected to the controller signal. The heat treatment tank 201 and the heat stabilization tank 203 are both equipped with temperature sensors connected to the monitoring module signal. The input end of the heat exchange tube 4 is connected to a heater and a circulating water pump connected to the control module signal.

[0056] The control module is provided with a raw material management unit, a heat exchange control unit and a stirring control unit;

[0057] The raw material management unit is used to manage the supply of raw materials in the raw material tank 3 and measure the remaining amount, so that the raw materials are supplied to the heat-insulating stirring tank 1 according to the preset ratio and speed;

[0058] The heat exchange control unit is used to control the temperature of the fluid in the heat exchange tube 4. It receives the real-time temperature information sent back by the temperature sensor and controls the operation of the heater and the circulating water pump according to the instructions of the processor;

[0059] The stirring control unit is used to control the stirring speed and time of the stirring structure 5 to ensure that the raw materials are evenly mixed in the heat-insulating stirring tank 1; when the pressure monitored by the pressure sensing belt is greater than the set value, the stirring control unit controls the electric heater and the electromagnet at the corresponding position to work at the set power;

[0060] The monitoring module monitors the temperature in the heat treatment tank 201 and the heat stabilization tank 203 in real time, and sends the temperature information to the processor, and the pressure monitoring value of the pressure sensing belt is uploaded to the monitoring module.

[0061] An environmentally friendly anti-rust film forming pretreatment process, the specific process includes:

[0062] A1, quantitatively feeding materials to the pretreatment structure 2 through the raw material tank 3; firstly, quantitatively feeding materials to the pretreatment structure 2 through the raw material tank 3, identifying the raw material output amount by the weight reduction of the materials in the raw material tank 3, and stopping feeding when the weight reduction of the materials in the raw material tank 3 reaches the set value;

[0063] A2, the material is input into the heat treatment tank 201, heated and melted, and then input into the heat stabilizing tank 203. At this time, a fluid of a set temperature is introduced into the heat exchange tube 4, and heat is exchanged with multiple heat stabilizing tanks 203 at the same time through the fluid introduced into the heat exchange tube 4, so that the temperature of the materials in the multiple heat stabilizing tanks 203 is uniformly exchanged to the set temperature; the set temperature is determined by those skilled in the art according to the melting temperatures of multiple raw materials, and the set temperature here is greater than or equal to the melting temperature of the raw material with the highest melting temperature; at this time, the temperature sensors in the multiple heat stabilizing tanks 203 detect that the temperatures of the materials therein are equal;

[0064] Different types of raw materials have different heat treatment temperatures in the heat treatment tank 201;

[0065] A3, after stabilizing the various materials to the same temperature in the heat stabilizing tank 203, the materials are input into the heat-insulating stirring tank 1 for stirring;

[0066] A4, during the stirring process, the electric heating plate on the stirring structure 5 performs local heating treatment on the coagulation in the raw material to ensure that the raw material does not coagulate inside and is stirred evenly;

[0067] A5, after the stirring is completed, the mixed raw materials are output.

[0068] When the stirring device is working, the mixed raw materials are kept warm. An auxiliary heating device can be installed on the stirring device. After the temperature of the heat-insulating stirring tank 1 drops, the heat-insulating stirring tank 1 can be timely heated for auxiliary heating to ensure that the materials therein are not easy to cool and condense.

[0069] This embodiment realizes that when the raw materials for the rust-proof film are pretreated, the melted raw materials are uniformly treated to the same temperature before mixing, so that after the high-temperature melted raw materials are in contact with the low-temperature molten raw materials, the high-temperature melted raw materials are not likely to cause local coagulation due to heat exchange in the contact area;

[0070] In addition, this solution does not require heating of the mixing tank during the mixing process, which is easy to save energy.

[0071] This embodiment realizes automation and intelligence of raw material supply, temperature control, stirring speed and time control by introducing a pretreatment control system, thereby improving the efficiency of pretreatment.

[0072] The stirring control unit can automatically control the stirring speed and time of the stirring structure according to preset parameters to ensure that the raw materials are evenly mixed in the heat-insulating stirring tank. At the same time, the electric heating plate on the stirring device can also perform local heating treatment on the clots in the raw materials to ensure that the raw materials do not coagulate inside and are stirred evenly.

[0073] In this embodiment, the stirring tank does not need to be heated as a whole during the stirring process, and only the electric heating plate on the stirring structure is used to locally heat the agglomerates in the raw materials, thereby greatly saving energy consumption.

[0074] In summary, before stirring the various raw materials, it is easy to stabilize the temperature of the melted raw materials to the same temperature before mixing them. The thermally stable temperature is maintained during the stirring process to reduce the heating requirements during stirring and save energy. The stirring process can be locally heated by the electric heating plate on the protective plate 504 to ensure that the raw materials are not easy to coagulate during stirring.

[0075] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
