Description

Technical Field

[0001] The utility model relates to the technical field of industrial automation, in particular to a low-temperature slow-burning control device for industrial resumed production gypsum powder. Background Art

[0002] Due to the development of power generation and chemical industries, a large amount of industrial by-product gypsum is generated during the production process, and the composition of the gypsum is complex. For different batches of by-product gypsum, their compositions will also vary greatly. Now, for the high-temperature heating treatment and reuse of industrial by-product gypsum, the production system is old. In the low-temperature slow-burning process, each device cannot be monitored and controlled in a timely manner. When the operator adjusts the temperature, there are untimely and non-standard operations, which will cause the operation of the low-temperature slow-burning equipment to be unstable, resulting in a series of problems such as unstable quality, low output, and increased energy consumption of the industrial by-product gypsum after low-temperature slow-burning. Therefore, the system needs to be transformed and upgraded.

[0003] The feeding method of industrial by-product gypsum calcination is one of the important factors to ensure output and quality. For the low-temperature slow-burning equipment of gypsum, due to excessive feeding, the temperature of the calcination equipment drops, and the temperature fluctuates greatly. The dihydrate content of the calcined gypsum powder is high. At the same time, too little feeding will cause the temperature of the calcination equipment to rise, and the anhydrous content of the calcined gypsum powder is high. Modern industry has strict requirements for feeding to improve the product qualification rate, and the feeding fluctuation is getting smaller and smaller, strictly controlled within a certain range. The task of automatic feeding adjustment is to maintain the temperature of the calcination equipment within a certain range. The main factors causing the temperature change of the calcination equipment are feeding change, hot air temperature change, air volume, and air pressure change. When the temperature fluctuation range at the discharge port is large, the temperature, flow rate, and feeding amount of the hot air should change accordingly. Manual operation can no longer meet the production requirements.

[0004] The traditional control method is for manual adjustment of the feeding amount according to the discharge temperature. Inevitably, there will be large temperature fluctuations, and long-term operation by workers will cause fatigue, bringing potential hazards to production. If an automatic control system is adopted, the controller can be used to monitor and analyze the discharge temperature in real time. Through the preset control target value, the controller will automatically track and adjust the hot air temperature, flow rate, and feeding amount, so as to achieve the constancy of the discharge temperature without manual intervention and adjustment. Therefore, a low-temperature slow-burning control device for industrial resumed production gypsum powder is proposed to solve the above problems. Summary of the Utility Model

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: A low-temperature slow-burning control device for industrial resumption of production of gypsum powder, including a bottom plate 21. The bottom plate 21 serves as the structural foundation of the entire device, providing a stable support and installation platform. All important components and mechanical parts are fixed on the bottom plate 21 to ensure the structural integrity and operation safety of the entire device.

[0036] Refer to Figure 1 andFigure 4 At the rear left side of the top of the bottom plate 21, a hot air device 20 is fixedly connected. At the rear side of the top of the bottom plate 21, a third pressure sensor 19 and a fourth temperature sensor 18 are fixedly connected. At the rear right side of the top of the bottom plate 21, a third temperature sensor 17 is fixedly connected.

These sensors monitor the working state of the device in real time, including changes in temperature and pressure. This data is crucial for adjusting operation parameters to ensure the stability of the firing process and product quality. At the left and right sides of the top of the receiving barrel 10, dust removal covers 8 are fixedly connected. At the top left and right sides of the receiving barrel 10, fans 7 are fixedly connected. At the rear top of the receiving barrel 10, a first temperature sensor 9 is fixedly connected.

[0037] At the front side of the top of the bottom plate 21, a plurality of air blowers 16 are fixedly connected. The inside of the hot air device 20 is communicated with the inside of the receiving barrel 10, and the inside of the air blower 16 is communicated with the inside of the receiving barrel 10. The hot air device 20 is responsible for providing necessary heat, and the hot air is evenly distributed inside the receiving barrel 10 through the air blower 16. This hot air circulation system helps to maintain temperature balance during the low-temperature slow firing process, optimize the firing efficiency and reduce energy consumption. The receiving barrel 10 is used for low-temperature slow firing of gypsum powder. The dust removal device 8 is installed at the top of the receiving barrel 10 to remove dust and particles generated during the processing, keep the working environment clean and reduce environmental pollution.

[0038] Working principle: First, pour the gypsum powder into the inside of the bin 2. Then, the stored gypsum powder is adjusted by the hand-operated air-integrated plug valve 3 and enters the screw conveyor 4 in a controlled manner. The screw conveyor 4 is responsible for continuously conveying the gypsum powder to the connecting pipe 23, and this connecting pipe 23 conveys the material from the bottom of the screw conveyor 4 to the top of the metering screw 5. The metering screw 5 plays a key role here. It ensures that the amount of gypsum powder output each time is accurate to meet the strict requirements for the amount of material during the firing process.

[0039] The gypsum powder coming out of the metering screw 5 is then conveyed to the conveyor 6. Inside the conveyor 6, the material conveying component starts to play a role. This component includes a main rotating roller 30 driven by a second motor 28, and a transmission belt 31 around the main rotating roller 30 and the driven rotating roller 15. The feeding plates 12 evenly distributed on the transmission belt 31 help to smoothly push the gypsum powder to the next processing station.

[0040] Before the gypsum powder enters the receiving barrel 10, it will be preheated by the hot air device 20. The hot air device 20 evenly distributes the heated air inside the receiving barrel 10 through the fan 16 to ensure that the gypsum powder is evenly heated throughout the receiving barrel 10, so as to achieve low-temperature slow firing. During this process, multiple temperature sensors and pressure sensors in the receiving barrel 10 monitor the firing environment in real time to ensure that the firing process is carried out under the best temperature and pressure conditions.

[0041] The dust removal device 8 is installed at the top of the receiving barrel 10 to effectively remove the dust and particles that may be generated during the firing process and keep the working environment clean. At the same time, the fans 7 on both sides of the receiving barrel 10 help to adjust the internal air flow to further optimize the firing effect.
