Description

Technical Field

[0001] This invention relates to the field of drying oven technology, specifically a novel intelligent drying oven. Background Technology

[0002] Granule dryers typically employ hot air drying, generating hot air through a furnace and blowing it onto the material to be dried by a fan to evaporate moisture. Traditional dryers usually use fixed fans or a single air duct structure, making it difficult to dynamically adjust the airflow direction and volume according to the actual placement of the material and the local moisture content. This results in significant differences in heat distribution between the edges and center of the dryer, leading to over-drying or under-drying in some areas, affecting the overall drying quality of the granular material. Furthermore, due to heat attenuation and time lag during hot air transmission, there is a time delay and energy loss as the hot air travels from the heat source to different locations. Existing dryers fail to effectively identify and compensate for these localized heat losses and fail to flexibly configure and adjust the air duct to adapt to these effects, further contributing to response lag and increased drying energy consumption.

The airflow and direction adjustment component is located on one side of the array of induced draft fans to independently control the airflow direction of each of the array of induced draft fans. Several array-point temperature measurement and reading components are also installed inside the drying chamber frame. These array-point temperature measurement and reading components are used to measure the actual heat reaching each drying point and analyze the heat lag at the actual low-heat drying point. The loss amount, the arrangement point temperature reading component is also used to measure the moisture content of the material at the low heat drying point, the local difference measurement execution component and the secondary verification signal correction unit are installed on one side of the dryer chamber frame, the local difference measurement execution component is signal connected to the arrangement point temperature reading component, the local difference measurement execution component analyzes the actual heat loss according to the measurement data of the arrangement point temperature reading component, and sends the adjustment signal to the air volume and direction adjustment component and the arrangement type exhaust fan, the secondary verification signal correction unit is used to read the adjustment command output by the local difference measurement execution component and determine the initial air direction of the arrangement type exhaust fan under the same drying range.

[0006] Preferably, the temperature reading assembly includes a drying surface measuring point heat output unit, a time lag error analysis unit, and a multi-point moisture content parameter input unit. The drying surface measuring point heat output unit and the multi-point moisture content parameter input unit are both installed in a rectangular array inside the dryer chamber frame to divide the inner side of the dryer chamber frame into several areas to be measured, thereby independently measuring the actual heat reaching each drying point. The time lag error analysis unit is signal-connected to the drying surface measuring point heat output unit.

[0007] Preferably, the heat output unit for measuring the drying surface includes an integrated bracket, a temperature sensing unit and an airflow sensing unit mounted on the integrated bracket, and the temperature sensing unit and the airflow sensing unit are connected to the local difference measurement execution component via a wireless signal transmitter.

The humidity sensor and the contact sensor are both installed at the output end of the electromagnetic thruster, and the humidity sensor and the contact sensor are connected to the local difference measurement execution component via a wireless signal transmitter.

[0009] Preferably, the local difference measurement execution component includes a local loss error measurement unit, a four-way airflow adjustment unit, and a body heat dissipation output unit.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, to address the issues of heat attenuation and time lag during hot air transmission, resulting in time delays and energy losses as hot air travels from the heat source to different locations, and the failure of existing dryers to effectively identify and compensate for such localized heat loss and flexibly configure and adjust the air duct to adapt to these effects, further leading to response lag and increased drying energy consumption, this invention proposes a novel intelligent drying chamber. This chamber includes a drying chamber frame 1, which integrates an airflow and direction adjustment component 2, a drying-side combustion heater 3, a combustion-side feeding furnace 4, and a series of induced draft fans 5. The airflow and direction adjustment component 2 is located on one side of the series of induced draft fans 5 to independently control the airflow direction of each fan. The drying chamber frame 1 also includes several temperature measurement and reading components 6 arranged at various points. Arranged inside the dryer chamber frame 1, the point temperature reading component 6 is used to measure the actual heat reaching each drying point and analyze the heat lag loss at the actual low-heat drying point. The point temperature reading component 6 is also used to measure the moisture content of the material at the low-heat drying point. A local difference measurement execution component 7 and a secondary verification signal correction unit 8 are installed on one side of the dryer chamber frame 1. The local difference measurement execution component 7 is signal-connected to the point temperature reading component 6. The local difference measurement execution component 7 analyzes the actual missing heat based on the measurement data of the point temperature reading component 6 and sends a debugging signal to the airflow and direction adjustment component 2 and the arranged induced draft fan 5. The secondary verification signal correction unit 8 is used to read the debugging command output by the local difference measurement execution component 7 and determine the initial airflow direction of the arranged induced draft fan 5 under the same drying range.

[0019] In one optional embodiment of this example, a front-end heating furnace 9 is provided on one side of the drying-side combustion heater 3, and a dust removal and heat dissipation box 91 is installed between the front-end heating furnace 9 and the drying-side combustion heater 3. The feed end of the front-end heating furnace 9 is threadedly connected to the combustion-side feeding furnace 4, and a through-type smoke exhaust assembly 31 is provided at one end of the drying-side combustion heater 3.

[0020] Both ends of the dryer chamber frame 1 are equipped with air guide plates 11. The air outlet of the induced draft fan 5 faces the air guide plate 11. A dehumidifying fan 12 is also provided between the induced draft fan 5 and the drying side combustion heater 3. A dehumidifying air duct 13 is fixedly connected to the bottom of the dehumidifying fan 12. The dehumidifying air duct 13 extends vertically downward to the bottom height of the induced draft fan 5. It should be noted that this embodiment also provides an operation method that eliminates the need for the airflow and direction adjustment component 2, and guides the airflow during drying solely by setting the air guide plate 11: The material to be dried is fed into the heating furnace 9 through the combustion end feeding furnace 4. After being heated by the heating furnace 9, the heat generated is guided to the inner position of the drying side combustion heater 3 by the dust removal heat dissipation box 91, and finally discharged into the dryer chamber frame 1 by the arranged induced draft fan 5. At the same time, due to the guidance of the arc-shaped air guide plate 11, the air source can be stably returned to the drying rack placed at the bottom of the arranged induced draft fan 5. This setting can effectively prevent the hot airflow from blowing directly onto the material. During the drying process, the moisture evaporated by the material at the bottom of the arranged induced draft fan 5 after drying is guided by the dehumidifying fan 12 and the dehumidifying air duct 13 and discharged to the outside. The flue gas generated by heating inside the heating furnace 9 and the dust removal heat dissipation box 91 is guided to the outside through the exhaust pipe in the connected exhaust assembly 31 and the fan installed at the top of the exhaust pipe.

[0021] In this embodiment, the workflow of the present invention includes the following steps: Step S1: After the material is fed in, the heat output to each drying point is centrally measured by the temperature reading assembly 6, and the heat loss due to time delay at the actual low heat drying point is analyzed.

[0022] Step S2: Then, the moisture content of the material in the actual low-heat area is measured by arranging the temperature reading components 6.

[0023] Step S3: After measurement, the local difference determination execution component 7 analyzes the actual missing heat based on the material moisture content and time lag error.

[0024] Step S4: After analyzing the missing heat, the local difference measurement execution component 7 sends a control signal to the air volume and direction adjustment component 2 and the arranged induced draft fan 5. The air volume and direction adjustment component 2 and the arranged induced draft fan 5 adjust the local induced draft volume when dissipating heat from the furnace body and replenish the drying surface.

[0025] Step S5: The secondary verification signal correction unit 8 reads the debugging command output by the local difference measurement execution component 7 and formulates the initial wind direction of the arranged induced draft fan 5 under the same drying range, as the initial application debugging value for the next drying of the same amount.

[0026] In one optional embodiment of this example, the temperature reading assembly 6 includes a drying surface measuring point heat output unit 61, a time delay error analysis unit 62, and a multi-point moisture content parameter input unit 63. The drying surface measuring point heat output unit 61 and the multi-point moisture content parameter input unit 63 are both installed in a rectangular array inside the dryer chamber frame 1 to divide the inner side of the dryer chamber frame 1 into several areas to be measured, and then independently measure the actual heat reaching each drying point. The time delay error analysis unit 62 is signal-connected to the drying surface measuring point heat output unit 61.

[0027] In this embodiment, since the drying space inside the dryer chamber frame 1 is large, the drying racks need to be arranged in order after being placed inside the dryer chamber frame 1 to facilitate the placement of more drying racks at once. Therefore, the drying surface measuring point heat output unit 61 and the multi-point moisture content parameter input unit 63 are distributed in a matrix and can correspond to the position of the drying racks, thereby determining whether the drying area where each drying rack is located is covered by heat during drying, and simultaneously obtaining the humidity of the material surface of each drying rack.

[0028] Furthermore, since different humidity levels require different drying times, the heat reduction due to incomplete heat coverage will further increase when the time lag error is reduced. Therefore, after the drying surface measuring point heat output unit 61 and the multi-point moisture content parameter input unit 63 are matrix-distributed, independent measurement can be completed to obtain accurate material moisture content and time lag error independent analysis of the actual missing heat for local difference measurement execution component 7 to perform further analysis.

[0029] In one optional embodiment of this example, the drying surface measuring point heat output unit 61 includes an integrated bracket, a temperature sensing unit and an air volume sensing unit mounted on the integrated bracket, and the temperature sensing unit and the air volume sensing unit are connected to the local difference measurement execution component 7 via a wireless signal transmitter.

[0030] In this embodiment, the temperature sensing unit and the air volume sensing unit are used to obtain the local drying temperature of the drying rack at their corresponding positions, and the data is uploaded to the local difference measurement execution component 7 by the wireless signal transmitter.

[0031] In an optional embodiment of this example, the multi-point moisture content parameter input unit 63 includes an electromagnetic thruster, a humidity sensor, and a contact sensor. The humidity sensor and the contact sensor are both installed at the output end of the electromagnetic thruster. The humidity sensor and the contact sensor are connected to the local difference measurement execution component 7 through a wireless signal transmitter.

[0032] In this embodiment, the humidity sensor and the contact sensor are used to obtain the humidity of the material on the drying rack at their corresponding positions. That is, after the material rack is pushed into the inner side of the drying chamber frame 1, the humidity sensor and the contact sensor are extended and pushed towards the material surface by the electromagnetic thruster until the contact sensor obtains a contact signal with the material surface. Then, the humidity sensor triggers a data acquisition signal and uploads it to the local difference measurement execution component 7 through the wireless signal transmitter.

[0033] In one optional embodiment of this example, the local difference measurement execution component 7 includes a local loss error measurement unit 71, an airflow four-way adjustment unit 72, and a body heat dissipation output unit 73. The airflow four-way adjustment unit 72 is signal-connected to the airflow and airflow direction adjustment component 2. The local loss error measurement unit 71 is signal-connected to the time delay error analysis unit 62 and the multi-point moisture content parameter input unit 63. The body heat dissipation output unit 73 is signal-connected to the arranged induced draft fan 5.

[0034] In this embodiment, the local loss error measurement unit 71 obtains the specific difference between the local temperature after obtaining the material moisture content and time delay error and the current drying requirement temperature to analyze the actual missing heat. The air volume four-way adjustment unit 72 sends control signals to the air volume and direction adjustment component 2 and the arranged induced draft fan 5. The air volume and direction adjustment component 2 and the arranged induced draft fan 5 switch the local induced draft volume used for furnace heat dissipation to the drying rack position that needs to be compensated for moisture content and time delay error (including drying air supply angle and air supply volume), assisting in the local heating of this part of the area.

[0035] In one optional embodiment of this example, the four-way airflow adjustment unit 72 includes an electrically operated airflow direction adjustment flap installed at the air outlet of the induced draft fan 5 and a means to control the airflow of the induced draft fan 5.

[0036] In this embodiment, the four-way airflow adjustment unit 72 is located outside the row of induced draft fans 5 and is used for the self-adjustment of each individual row of induced draft fans 5. The airflow and direction adjustment component 2 is a direction adjustment flap built into the row of induced draft fans 5. When switching local airflow, the four-way airflow adjustment unit 72 and the airflow and direction adjustment component 2 work together to adjust the airflow direction and airflow.

[0037] In one optional embodiment of this example, the secondary verification signal correction unit 8 is signal-connected to the body heat dissipation output unit 73. After the body heat dissipation output unit 73 outputs the air direction and air volume adjustment command, the secondary verification signal correction unit 8 records the current drying material placement range and records the adjusted air direction and air volume adjustment parameters of the arranged induced draft fan 5.

[0038] In one optional embodiment of this example, both the drying-side combustion heater 3 and the induced draft fan 5 are installed on the top of the dryer chamber frame 1, with the drying-side combustion heater 3 and the induced draft fan 5 arranged horizontally at the furnace body end. In this example, the purpose of arranging the drying-side combustion heater 3 and the induced draft fan 5 in the same direction is to provide auxiliary heat dissipation for the drying-side combustion heater 3 through the induced draft fan 5, and to further carry the heat generated during heat dissipation to the location of the drying rack. Furthermore, since the top of the dryer chamber frame 1 has a larger ventilation path, the heat dissipation efficiency of the induced draft fan 5 when blowing air in the direction of the combustion end feeding furnace 4 can be guaranteed, and the drying dead corner inside the dryer chamber frame 1 can be further reduced.

[0039] The working principle and usage process of this invention are as follows: By setting the air volume and direction adjustment component 2 and the arranged induced draft fan 5 on the top side of the dryer chamber frame 1, the air duct directly outputs air to the furnace body in the drying state, causing the furnace body to generate heat and spread rapidly to the surrounding area, thus achieving heat dissipation. During the drying process, the current drying quantity and the position of the drying rack are first recorded by the secondary verification signal correction unit 8. Then, the temperature reading component 6 measures the heat output to each drying point and the moisture content of the material in the actual low-heat area, and analyzes the heat loss due to time lag at the actual low-heat drying point. Based on the moisture content of the material and the time lag error, the actual heat loss is adjusted, and the air volume and direction adjustment component 2 is controlled to supplement the local air volume of the arranged induced draft fan 5 when dissipating heat from the equipment into the drying surface, so as to achieve accurate compensation for the heat loss in each area, making the internal temperature of the dryer uniform and avoiding the problem of local over-drying or under-drying.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
