Description

Technical Field

[0001] This utility model relates to a precise temperature control system for inorganic powder modification, belonging to the field of temperature control technology. Background Technology

[0002] In the process of inorganic powder modification, temperature is one of the key factors affecting the modification effect. Precise temperature control can ensure a sufficient and stable chemical reaction between the modifier and the powder, thereby improving the modification quality and performance of the powder. However, existing powder modification temperature control systems have many shortcomings.

[0003] Traditional temperature control systems mostly use simple temperature sensors and heating or cooling devices, resulting in low temperature control accuracy, often with errors of ±5℃ or even greater. This leads to large temperature fluctuations during the modification process, making it difficult to ensure that the modification reaction takes place under optimal temperature conditions, thus affecting the modification effect of the powder and the stability of product quality.

[0004] Furthermore, existing temperature control systems lack comprehensive monitoring and intelligent adjustment capabilities for the modification environment. They cannot adjust the temperature in real time according to the characteristics of the powder, the requirements of the modification process, and changes in environmental factors, leading to energy waste and low production efficiency. Therefore, there is an urgent need for a powder modification temperature control system capable of achieving precise temperature control. Summary of the Invention

[0005] The purpose of this invention is to address the lack of comprehensive monitoring and intelligent adjustment capabilities of existing temperature control systems for the modification environment, which prevents them from adjusting the temperature in real time according to the characteristics of the powder, the requirements of the modification process, and changes in environmental factors. This invention proposes a precise temperature control system for inorganic powder modification.

[0008] The water-cooled channel is connected to a water pump, which supplies water to the water-cooled channel from a water storage tank.

[0009] The PLC controller is installed inside the PLC control panel, which is installed next to the modified machine cylinder.

[0010] The bottom of the modified barrel is equipped with a stirrer, which is driven by a motor.

[0011] The beneficial effects of this invention are as follows: The temperature control system, through a high-precision temperature sensor and advanced control algorithm, achieves precise control of the powder modification temperature, with a temperature control accuracy of ±0.15℃. This ensures that the modification reaction can proceed under optimal temperature conditions, improving the powder modification effect and product quality stability.

Detailed Implementation

[0015] The specific embodiments of this utility model are as follows: Figure 1 As shown.

[0016] This embodiment discloses a precise temperature control system for inorganic powder modification, comprising a modifying machine cylinder 1, a stirrer 2, a motor 3, a platinum resistance temperature sensor 4, an electric heating element 5, a water cooling channel 6, a water storage tank 7, a small water pump 8, and a PLC control panel 9. The water storage tank 7 is constructed of cement, and the modifying machine cylinder 1 is installed on top of it.

[0017] The specific layout of reservoir 7 is as follows: Figure 2 As shown. The water-cooling channel 6 is distributed in an extended spiral needle shape, with an inlet 61 and an outlet 62 at each end. The inlet 61 enters the water storage tank 7 through a small water pump, and the outlet 62 is directly connected to the water storage tank 7. The electric heating tubes 5 are distributed close to the water-cooling channel 6 according to the direction of the water-cooling channel 6 in the interlayer of the modified machine cylinder 1.

[0018] During the powder modification process, motor 3 drives the impeller of stirrer 2 to rotate at high speed. Platinum resistance temperature sensors 4 are distributed at the bottom, top, and bottom of the inner wall of the modifying machine cylinder 1. These temperature sensors use high-precision temperature measuring elements such as thermocouples or resistance thermometers, achieving a measurement accuracy of ±0.15℃. They can collect temperature data during the powder modification process in real time and accurately, converting it into electrical signals and transmitting it to the PLC controller on the PLC control panel 9. The PLC controller collects the temperature data inside the modification equipment in real time, compares the actual temperature with the preset temperature, calculates the temperature deviation according to the preset PID control algorithm, and outputs corresponding control commands. If the actual temperature is lower than the preset temperature, the PLC control panel 9 will turn on the electric heating tube 5 to heat up the temperature; if the actual temperature is higher than the preset temperature, the PLC control panel 9 will start the small water pump 8 to pump the water in the water storage tank 7 into the water cooling channel 6; the inlet 61 pumps the cold water from the water storage tank 7 into the water cooling channel 6 through the small water pump 8. The cold water carries away the heat of the modified cylinder and is discharged into the water storage tank 7 through the outlet 62. The cycle continues until the temperature of the modified cylinder returns to the preset temperature.

[0019] The working principle of a platinum resistance temperature sensor is based on the characteristic that the resistance of platinum changes with temperature. When the temperature changes, the resistance of the platinum resistance sensor also changes accordingly. The temperature of the object being measured is calculated by measuring the change in its resistance. Typically, the platinum resistance sensor is connected to a circuit with a certain current flowing through it. According to Ohm's law, the resistance value is obtained by measuring the voltage across the resistor. Then, using a pre-calibrated resistance-temperature correlation, the resistance value is converted into a temperature value.
