Description

Technical Field

[0001] This invention relates to the field of intelligent drying oven systems, and more particularly to a large-capacity intelligent drying oven system. Background Technology

[0002] The moisture detection process for bulk resource commodities mainly consists of four steps: first, weighing 1-3 kg of sample for later use; second, heating and constant-weighting in an oven; third, controlling the oven to cool down by shutting off the power; and fourth, data processing. However, the existing oven data processing and sample drying processes are independent, time-consuming, and lengthy, easily introducing human interference. When a large oven is drying multiple samples simultaneously, asynchronous constant-weighting due to sample characteristics can lead to repeated opening and closing of the oven door, easily causing internal temperature fluctuations and sample spillage, resulting in experimental failure. Furthermore, samples awaiting constant weight need to be weighed multiple times. The sample to be weighed needs to be weighed immediately. The weighing device should also use a heat-insulating device to prevent heat conduction. Taking manganese ore as an example, the difference between two weighings should be less than 0.05% of the initial mass. If the sample weight is 3000g, the difference between two weighings should be less than 1.5g. If the weather humidity is high, the sample is prone to absorbing moisture, or if the operator's weighing technique is not skilled and fast enough, the weighing data is very likely to cause errors. Moreover, the constant weight process may be done once or multiple times, which consumes a lot of time and requires personnel to be on duty for a long time. If the drying time is controlled solely by experience, it is easy to cause insufficient drying or over-drying, which has drawbacks. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides a large-capacity intelligent drying oven system that minimizes human interference, ensures data accuracy, and features fully automated weighing throughout the entire process. This system automatically determines the experimental endpoint, comprehensively meets the requirements of constant weight operation, provides objective, truthful, and accurate data, minimizes experimental time, significantly improves work efficiency, saves energy, eliminates subsequent data processing time, and prevents sample spillage without interruption. It also effectively avoids potential burns to personnel and equipment damage caused by hot weighing.

[0004] The objective of this invention is achieved through the following technical solution: A large-range intelligent drying oven system includes an oven, a door, extended legs, a horizontal iron plate, a tray, a balance, heating resistors, and lifting rods. The oven is connected to the door via hinges. The door has an observation window and a handle. The oven is equipped with a switch and a drying chamber. Heating resistors are located on both sides of the drying chamber and connected to the oven. Extended legs are connected to the lower part of the oven. The oven has support rod through-holes that are adapted to the lifting rods. The lifting rods pass through the support rod through-holes. The upper end of the lifting rods is connected to a sample stage, which is connected to the tray. The lower end of the lifting rods is connected to a horizontal iron plate, which is connected to the balance.

[0005] This invention relates to an electromagnetic relay connected to an indicator light, which in turn is connected to an oven. The oven is connected to a manually reset electromagnetic relay, which is then connected to a power cord. The power cord is connected to a computer, which is connected to the power cord via a switch. The power cord is connected to a printer via a switch, which is also connected to a power cord. The power cord is connected to a balance, which is connected to the power cord via a switch. The power cord is then connected to the electromagnetic relay via a switch, and the electromagnetic relay is connected to a power source. Beneficial effects

[0006] This invention relates to an oven system comprising a weighing oven, an intelligent oven electrical control system, and an intelligent oven data processing system. After the intelligent oven and its associated equipment are powered on, the weighing oven transmits data to the data processing system via data acquisition. As the oven heats up and the sample dries, the data processing system automatically plots a curve of sample mass versus time. According to standard requirements, the data processing system automatically determines whether the sample has reached constant weight. If the sample has not reached constant weight, the oven continues operating; if the sample has met the constant weight requirement, the system automatically calculates the moisture content, stores the data, and simultaneously issues a stop-experiment command. Upon receiving the stop-experiment command, the intelligent oven electrical control system automatically shuts off the oven power, stops data acquisition, and the oven enters a cooling state, while the system enters a standby state.

[0007] This invention features a sample stage and a horizontal iron plate positioned at the upper and lower ends of a lifting support rod, providing a weighing fulcrum for the sample to be constant-weighted within the balance weighing tray. This ensures the sample remains within the drying chamber throughout the constant-weighting process, preventing inconsistencies in sample constant-weight due to operator inexperience or slow weighing techniques, heat conduction with the balance sensor, or moisture absorption by the sample in high humidity conditions. This also avoids issues when drying multiple samples simultaneously in the oven, as different sample characteristics lead to asynchronous constant-weighting, causing repeated opening and closing of the oven door, resulting in temperature fluctuations and sample spillage, potentially leading to experimental failure. This invention reduces human interference, improves drying efficiency, and allows for adjustment of the lifting support rod height based on the actual volume of the sample to be constant-weighted, ensuring the sample is centered within the drying chamber and maintaining a level sample tray, thus enhancing drying effect and efficiency. The structure is rationally designed.

[0008] This invention minimizes human error, operates fully automatically without interruption, automatically stores data, and automatically generates reports, ensuring data accuracy. The fully automated weighing system automatically determines the experimental endpoint, comprehensively meeting the requirements of constant weight operation. While providing objective, accurate, and truthful data, it also minimizes experimental time, significantly improving work efficiency and saving energy. Firstly, the continuous operation mode ensures uninterrupted experimentation. Secondly, it detects the experimental endpoint immediately and ends the experiment promptly, avoiding wasted time. Thirdly, it allows the oven to enter a cooling state as early as possible, preparing for the next sample injection. Fourthly, the automatic generation of data and reports eliminates subsequent data processing time and ensures experimental safety. The uninterrupted operation prevents sample spillage and effectively avoids burns and equipment damage that may occur during hot weighing. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A large-scale intelligent drying oven system includes an oven 01, a door 02, extended legs 06, a horizontal iron plate 07, a tray 08, a balance 09, heating resistors 10, and lifting support rods 11. The oven 01 is connected to the door 02 via hinges. The door 02 has an observation window 03 and a handle 04. The oven 01 is equipped with a switch 05 and a drying chamber 13. Heating resistors 10 are located on both sides of the drying chamber 13 and are connected to the oven 01. The extended legs 06 are connected to the lower part of the oven 01. This device consists of a weighing oven, an intelligent drying oven electrical control system, and an intelligent drying oven data processing system. After the intelligent drying oven and its supporting equipment are powered on, the weighing oven will transmit data to the data processing system through data acquisition. As the oven heats up and the sample dries, the data processing system will automatically plot the sample mass versus time curve. According to standard requirements, the data processing system will automatically determine whether the sample has a constant weight. If the sample does not reach constant weight, the oven continues to operate; if the sample has met the constant weight requirement, the system will automatically calculate the moisture content, store the data, and issue a stop-experiment command. Upon receiving the stop-experiment command, the intelligent oven control system automatically shuts off the oven power, stops data acquisition, and the oven enters a cooling state, while the system enters a standby state. The oven 01 has a support rod through-hole 12, which is adapted to a lifting support rod 11. The lifting support rod 11 passes through the support rod through-hole 12. The upper end of the lifting support rod 11 is connected to a sample stage 14, which is connected to a tray 08. The lower end of the lifting support rod 11 is connected to a horizontal iron plate 07, which is connected to a balance 09. The sample stage 14 and the horizontal iron plate 07 are respectively positioned at the upper and lower ends of the lifting support rod 11, providing a weighing fulcrum for the sample to be constant-weighted within the weighing tray 08 of the balance 09, ensuring that it remains within the drying chamber during the constant-weighting process. Within 13, to prevent heat conduction in the sample during sample transfer and weighing due to insufficient operator skill or speed, or to prevent moisture absorption by the sample due to excessive humidity, thus affecting the accuracy of the weighing data, and to avoid uneven weighing when drying multiple samples simultaneously in oven 01 due to different sample characteristics, causing repeated opening and closing of oven 01 during the constant weight process, resulting in temperature fluctuations and sample spillage, leading to experimental failure, this design reduces human interference, improves drying efficiency, and allows for adjustment of the support height of the lifting rod 11 according to the actual volume of the sample to be constant-weighted, ensuring that the constant-weighted sample is placed in the center of the drying chamber 13, improving its drying effect and efficiency. The structure is reasonable.

[0013] Example 2: In this invention, power line L1 is connected to electromagnetic relay KM1 via a switch. Electromagnetic relay KM1 is also connected to indicator light M5 and manual reset electromagnetic relay KM2. Indicator light M5 is connected to oven M4. Oven M4 is connected to manual reset electromagnetic relay KM2. Manual reset electromagnetic relay KM2 is connected to power line L2. Power line L2 is connected to computer M3. Computer M3 is connected to power line L1 via a switch. Power line L1 is connected to printer M2 via a switch. Printer M2 is connected to power line L2. Power line L2 is connected to balance M1. Balance M1 is connected to power line L1 via a switch. Computer M3 controls the switching of electromagnetic relay KM1. This device minimizes human error, operates fully automatically without interruption, automatically stores data, and generates reports, ensuring data accuracy. The fully automated weighing system automatically determines the experimental endpoint, comprehensively meeting the requirements of constant weight operation. While providing objective, accurate, and reliable data, it also minimizes experimental time, significantly improving work efficiency and saving energy. Firstly, the continuous operation mode ensures uninterrupted experimentation; secondly, it detects the experimental endpoint immediately and ends the experiment promptly, avoiding wasted time; thirdly, it allows the oven to enter a cooling state as early as possible, preparing for the next sample injection; and fourthly, the automatic generation of data and reports eliminates subsequent data processing time. Overall, it improves work efficiency by at least 200% while ensuring experimental safety. The uninterrupted operation prevents sample spillage and effectively avoids burns and equipment damage that may occur during hot weighing.

[0014] Example 3: A method for operating a large-capacity intelligent drying oven system includes the following steps: 1. Connect the power supply, start the computer and balance, and open the self-written data processing program.

[0015] 2. Place a tray filled with about 2kg of sample onto the sample stage inside the modified oven. If the sample stage is not level, you can adjust it by turning the bolts.

[0016] 3. Turn on the oven power, close the oven door, set the temperature, and start heating. At this time, the sample mass on the sample stage is dynamically and continuously transmitted to the computer program through the balance connected to the bottom. The computer program dynamically plots the sample mass change curve.

[0017] 4. Based on the computer's self-developed algorithm, when the balance data reaches a constant weight, the program automatically saves the data, plots a curve of sample mass versus time, generates an inspection report, and performs a computer restart operation.

[0018] 5. When the computer is powered off, the motherboard power supply and the USB port power supply are cut off. At this time, the electromagnetic relay KM1 in the control circuit is disconnected, and the main circuit KM1 switch is also disconnected. The oven stops heating and the indicator light goes out. Simultaneously, the electromagnetic relay KM2 is disconnected, and the KM2 switch, which requires manual reset, is also disconnected.

[0019] 6. After the computer restarts, the electromagnetic relay KM1 in the control circuit will engage, and the main circuit switch KM1 will also engage simultaneously. To protect the oven, the KM2 switch needs to be manually reset and cannot be automatically turned off, so the oven will not start heating automatically.

[0020] 7. When the KM2 switch is manually closed, it is equivalent to resetting the entire system. Place a new sample in the system to start heating; the indicator light will illuminate. Repeat the above steps.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
