[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, the paint production control system mainly includes structures such as a floor scale 1, a metering tank 2, a reactor 3, and a central control room.

[0023] The metering tank 2 is connected to the floor scale 1, and a vacuum pump is installed on the pipeline connecting the two. Under the action of the vacuum pump, the material on the bottom can be passed into the metering tank 2.

[0024] The reaction kettle 3 is connected to the metering tank 2, and the metering tank 2 is located above the reaction kettle 3. The reaction kettle 3 can receive the material added from the metering tank 2, and the metering tank 2 is provided with a flow valve for adding the material.

[0025] Wherein, weighing modules are installed on the metering tank 2 and the reactor 3, which can calculate the weight of the materials therein in real time.

[0026] In addition, a temperature sensor and a pressure sensor are installed on the reactor 3 to measure the temperature, pressure and other conditions in the reactor 3 in real time.

[0027] The weighing scale 1, the measuring tank 2 and the reactor 3 are all connected to the central control room, which can not only control the operation of each device, but also predict the temperature and pressure changes in the reactor in advance through algorithm calculations.

[0028] In addition, there is a cooling water valve in the reactor 3, which is connected to a condenser 4, and the condenser 4 is connected to a water separator 5. Cooling water can be introduced into the reactor 3 through the water separator 5, the condenser 4 and the cooling water valve to adjust its internal temperature.

[0029] When using the device, the operator first generates a production formula by inputting the weight of the required materials, and then places the corresponding materials on the scale 1 according to the production formula. The materials are then added to the metering tank 2 through the vacuum pump, and then passed from the metering tank 2 to the reactor 3. Among them, the weighing modules on the metering tank 2 and the reactor 3 can monitor the material addition in real time, and when the weight required by the formula is reached, the system will automatically stop adding materials.

[0030] During the above-mentioned material addition process, the system calculates the material addition flow rate through the time required to add the material in this process, and cooperates with the weighing module to properly control the flow valve on the metering tank 2, so as to achieve the uniform addition of the material in the metering tank 2 to the reactor 3, so that the reaction proceeds smoothly.

[0031] The system can transmit the data detected by the temperature sensor and pressure sensor in the reactor 3 to the central control room in real time to form a data map. The central control room predicts the situation in the reactor 3 in advance through algorithm calculation and performs advance processing. For example, when it is predicted that the temperature rise rate in the reactor 3 is accelerating, the cooling water valve can be opened in advance to supply cooling water, and the opening of the cooling water valve can be appropriately adjusted to control the temperature of the material in the reactor 3 in real time and achieve the stability of the reaction temperature.

[0032] In addition, the central control room is also connected with an audible and visual alarm device, an emergency stop device, a temperature interlock device and a pressure interlock device, so that the system can detect various data anomalies in the reactor 3, notify the workshop production personnel in time, take corresponding actions, and ensure production safety.

[0033] like Figure 2 As shown, in order to save space and improve efficiency, multiple paint production control systems can be connected to each other during use. When connected, the metering tanks 2 of each paint production control system can be connected, and the condensers 4 of each paint production control system are connected to the same water distributor 5, that is, the same water distributor 5 can be used to supply cooling water to each reactor 3.

[0034] like Figure 3 As shown in the figure, when designing the material reaction processing of certain specific processes, it is often necessary to add an inhibitor. Figure 1 The paint production control system shown is provided with an inhibitor container 6 connected to the reaction kettle 3 for adding the inhibitor to the reaction kettle 3 to facilitate the reaction.

[0035] like Figure 4 As shown, when multiple Figure 3 When the paint production control systems are connected to each other, the reactors 3 of each paint production control system can be connected to the same inhibitor container 6, that is, the same inhibitor container 6 can be used to supply the inhibitor to each reactor 3.

[0036] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
