[0002] In the ceramic firing process, kiln equipment, as core production equipment, has a significant impact on the quality and production efficiency of ceramic products due to its stable and precise operating conditions. During kiln operation, the setting and adjustment of the drive frequency of each inverter is crucial for ensuring the normal and efficient operation of the equipment. However, under traditional operating modes, the control of the inverter drive frequency in kiln equipment is primarily manual.

BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 The invention discloses a flow chart of the steps of a transmission frequency control method for kiln equipment. DETAILED DESCRIPTION

[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and are not to be construed as limiting the present invention.

[0039] A method for controlling the transmission frequency of a kiln device comprises the following steps:

[0040] Step S1: collecting the actual transmission frequency of each inverter in the kiln equipment;

[0041] Step S2: According to the production demand of ceramics, the actual transmission frequency of the frequency converter in the kiln equipment is adjusted accordingly;

[0042] When the transmission frequency of a single inverter in the kiln equipment needs to be adjusted in the production of ceramics, the inverter to be adjusted is determined, and the target transmission frequency of the inverter to be adjusted is set, and the actual transmission frequency of the inverter to be adjusted is adjusted to reach the target transmission frequency of the inverter to be adjusted;

[0043] When the transmission frequencies of all inverters in the kiln equipment need to be adjusted in the production of ceramics, a unified target transmission frequency is set, and the actual transmission frequencies of all inverters in the kiln equipment are uniformly adjusted so that the transmission frequencies of all inverters reach the unified target transmission frequency;

[0044] When the drive frequency of the inverter needs to be adjusted according to the firing cycle in ceramic production requirements, the target drive frequency of each inverter in the kiln equipment is calculated according to the preset firing cycle, and the actual drive frequency of each inverter in the kiln equipment is adjusted so that the drive frequency of each inverter reaches the corresponding target drive frequency.

[0045] A transmission frequency control method for kiln equipment in this solution, such as Figure 1As shown, the first step is to collect the actual transmission frequency of each frequency converter in the kiln equipment. In this embodiment, by collecting the actual transmission frequency of each frequency converter in the kiln equipment, the operation status of each component in the kiln equipment can be mastered in real time. The second step is to adjust the actual transmission frequency of the frequency converter in the kiln equipment accordingly according to the production demand of ceramics; when the transmission frequency of a single frequency converter in the kiln equipment needs to be adjusted in the production demand of ceramics, the frequency converter to be adjusted is determined, and the target transmission frequency of the frequency converter to be adjusted is set, and the actual transmission frequency of the frequency converter to be adjusted is adjusted to reach the target transmission frequency of the frequency converter to be adjusted; when the transmission frequency of multiple frequency converters in the kiln equipment needs to be adjusted in the production demand of ceramics, multiple frequency converters to be adjusted are determined, and the target transmission frequency of each frequency converter to be adjusted is set respectively, and the actual transmission frequency of each frequency converter to be adjusted is adjusted one by one to reach the corresponding target transmission frequency; when the transmission frequency of multiple frequency converters in the kiln equipment needs to be adjusted When production needs necessitate adjustment of the transmission frequencies of all frequency converters in the kiln equipment, a unified target transmission frequency is set, and the actual transmission frequencies of all frequency converters in the kiln equipment are uniformly adjusted so that the transmission frequencies of all frequency converters reach the unified target transmission frequency. When ceramic production needs necessitate adjustment of the transmission frequencies of the frequency converters according to the firing cycle, the target transmission frequency of each frequency converter in the kiln equipment is calculated based on the preset firing cycle, and the actual transmission frequency of each frequency converter in the kiln equipment is adjusted so that the transmission frequency of each frequency converter reaches the corresponding target transmission frequency. In this embodiment, during the actual ceramic production process, frequency converters in different locations may have different effects on parameters such as the temperature and atmosphere in different areas of the kiln equipment. When production needs change and only the actual transmission frequency of a single frequency converter needs to be adjusted, the actual transmission frequency of the frequency converter to be adjusted is adjusted so that it reaches the target transmission frequency of the frequency converter to be adjusted, thereby enabling precise control of parameters such as the temperature and atmosphere in a specific area of the kiln equipment. When production demands change and the actual transmission frequencies of multiple inverters need to be adjusted, the actual transmission frequencies of the inverters to be adjusted are adjusted one by one to achieve the corresponding target transmission frequencies, enabling precise control of parameters in multiple specific areas within the kiln equipment. When ceramic production demands change on a large scale, such as requiring batch adjustments to the transmission frequencies of all inverters in the kiln equipment, uniformly adjusting the actual transmission frequencies of all inverters allows the kiln equipment to quickly and efficiently adapt to the new production requirements, ensuring that parameters such as temperature and atmosphere throughout the kiln equipment simultaneously meet the new production standards, shortening production adjustment time and improving production response speed.When production demands change and the inverter's transmission frequency needs to be adjusted according to the firing cycle, by calculating the target transmission frequency of each inverter based on the preset firing cycle and adjusting it accordingly, it is possible to achieve refined control of the kiln equipment's transmission frequency, ensuring that the kiln equipment can provide the most suitable temperature, atmosphere and other conditions at each stage of the firing process.

[0046] Compared with the traditional method of regulating the transmission frequency of the inverter in kiln equipment that relies on manual operation, this solution automatically regulates the transmission frequency of the inverter in the kiln equipment according to the production needs of ceramics, so that it can accurately meet the actual production needs of ceramics, thereby improving the accuracy of transmission frequency regulation, thereby ensuring the stability of key parameters such as temperature and atmosphere in the kiln equipment, and thus improving the firing quality of ceramic products.

[0047] Preferably, in step S3, regulating the actual transmission frequency of the frequency converter in the kiln equipment specifically includes the following sub-step: regulating the actual transmission frequency of the frequency converter in the kiln equipment in a stepwise manner. Specifically, by regulating the actual transmission frequency of the frequency converter in the kiln equipment in a stepwise manner, the kiln equipment is ensured to operate in a stable and orderly manner, accurately adapting to the actual production needs of ceramics.

[0048] In one embodiment, if the actual transmission frequency of an inverter in the kiln equipment is 25Hz and the target transmission frequency of the inverter is 45Hz, then the transmission frequency needs to be increased in four times. The first time is to increase the transmission frequency to 30Hz, the second time is to increase the transmission frequency to 35Hz, the third time is to increase the transmission frequency to 40Hz, and the fourth time is to increase the transmission frequency to 45Hz.

[0049] Preferably, in step S4, the target transmission frequency of each inverter in the kiln equipment is calculated according to the preset firing cycle, wherein the calculation formula of the firing cycle is as follows:

[0050]

[0051] Where T represents the firing cycle; n represents the total number of frequency converters in the kiln equipment; f i represents the target transmission frequency of the i-th inverter in the kiln equipment; a i Indicates the number of boxes carried by the i-th inverter in the kiln equipment; b i It represents the transmission coefficient of the i-th inverter in the kiln equipment.

[0052] In one embodiment, when 5 frequency converters are provided in the kiln equipment, and the target transmission frequencies of the 5 frequency converters are the same, the number of boxes carried by the 5 frequency converters is 2, the transmission systems of the 5 frequency converters are 75.3, and the preset firing cycle is 30 minutes, then the above parameters are substituted into the calculation formula of the firing cycle, and the target transmission frequencies of the 5 frequency converters are all 25.1Hz.

[0053] Preferably, in step S3, during the process of regulating the actual transmission frequency of the frequency converter in the kiln equipment, the following steps are further included: comparing the target transmission frequency of the frequency converter in the kiln equipment with the actual transmission frequency;

[0054] When the target transmission frequency of the inverter in the kiln equipment is greater than the actual transmission frequency, the transmission frequency of each inverter in the kiln equipment is adjusted in the order from the back end to the front end of the kiln equipment;

[0055] When the target transmission frequency of the frequency converter in the kiln equipment is lower than the actual transmission frequency, the transmission frequency of each frequency converter in the kiln equipment is adjusted in order from the front end to the back end of the kiln equipment.

[0056] In this embodiment, when the target transmission frequency of the inverter in the kiln equipment is greater than the actual transmission frequency, it means that the transmission speed in the front-end area of the kiln equipment is too fast. In this case, the transmission frequency of each inverter is adjusted in a step-by-step manner from the rear end of the kiln equipment to the front end. This can prevent the ceramic products from colliding and squeezing with each other in the kiln due to the excessive transmission speed at the front end of the kiln equipment, thereby causing production failures such as kiln blockage. When the target transmission frequency of the inverter in the kiln equipment is less than the actual transmission frequency, it means that the transmission speed in the rear-end area of the kiln equipment is too slow. In this case, the transmission frequency of each inverter is adjusted in a step-by-step manner from the front end of the kiln equipment to the rear end. This can prevent the ceramic products from colliding and colliding with each other due to the excessive transmission speed at the rear end of the kiln equipment, thereby causing kiln blockage, thereby ensuring the stable and efficient operation of the kiln equipment.

[0071] Preferably, the frequency control module includes a frequency control submodule for controlling the actual transmission frequency of the frequency converter in the kiln equipment in a stepwise manner. In this embodiment, the frequency control submodule ensures that the kiln equipment operates in a stable and orderly manner, accurately adapting to the actual production needs of ceramics.

[0072] Preferably, in the calculation module, the calculation formula for the firing cycle is as follows:

In this case, by executing the first control module, it is possible to prevent the ceramic products from colliding and squeezing with each other in the kiln due to the excessive transmission speed at the front end of the kiln equipment, thereby causing production failures such as kiln blockage.
