Description

Technical Field

[0001] This invention belongs to the field of material channel temperature control, specifically a temperature control system for a glass melt flow channel. Background Technology

[0002] Molten glass is a highly viscous substance. After the glass wool raw material melts, it needs to be conveyed to the production line through a conveyor channel at a specific temperature. During the conveying process, the temperature of the molten glass needs to be maintained to prevent solidification, thereby ensuring the quality of glass products and production efficiency. Therefore, the temperature control system plays a crucial role in the molten glass flow channel.

[0003] In traditional glass melt flow channel temperature control systems, uniform heating and cooling are used for the entire channel, keeping it under high load for extended periods. This increases the economic burden and introduces hidden risks for businesses. Furthermore, the low precision of the adjustment reduces the quality of glass products and production efficiency.

[0004] Therefore, the present invention discloses a temperature control system for a glass melt flow channel to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a glass melt flow channel temperature control system to solve the technical problem of difficulty in accurately controlling and stably maintaining the channel temperature based on the regional temperature in the glass melt flow channel. This invention solves the above-mentioned problem by dividing the channel into a natural cooling zone and a heating zone, processing the regional temperature of the heating zone to obtain a characteristic temperature, and controlling the channel temperature based on the characteristic temperature.

[0006] To achieve the above objectives, a first aspect of the present invention provides a temperature control system for a glass melt flow channel, comprising: a region planning module, and a temperature control module and a database connected thereto;

[0007] The area planning module is used to divide the material channel into several small areas, collect the temperature of the small areas through temperature sensors, and dynamically plan the material channel based on the limited temperature to obtain the control area; wherein, the limited temperature refers to the maximum temperature that the material channel needs to maintain glass quality as set through experience, and the control area includes a natural cooling area and a heating area.

[0008] The temperature control module is used to acquire the temperature of each small area in the heating area, mark the temperature of each small area in the heating area as the area temperature, process the area temperature to obtain the characteristic temperature, and control the temperature of the material channel based on the characteristic temperature.

[0009] The database is used to store data.

[0010] Preferably, the dynamic planning of the material channel based on a defined temperature to obtain the control zone includes:

[0011] The first small area at a defined temperature is obtained by a temperature sensor and marked as the defined area; the area before the defined area is marked as the natural cooling area, and the area after the defined area is marked as the heating area. The information of the natural cooling area and the heating area is stored in a database.

[0012] Preferably, the process of processing the regional temperature to obtain the characteristic temperature includes:

[0013] The small areas within the heating zone are sorted and a sorting table is created. The area temperatures are extracted sequentially from the sorting table and added to the feature temperature determination to obtain the feature temperature. The sorting method prioritizes areas closer to the material channel, with the material channel distance calculated along the material channel and extracted from the database.

[0014] Preferably, the characteristic temperature determination includes:

[0015] Extract the regional temperature and establish a temperature group based on the extracted regional temperature; obtain the variance of the regional temperature group and determine whether the variance is less than a set value; if yes, add the new regional temperature and re-determine the feature temperature; where the set value is obtained through experience, and the new regional temperature refers to the temperature of the next regional temperature.

[0016] No, mark the temperature of this area as not meeting the criteria for this characteristic temperature judgment, and mark the average of this temperature group as the same characteristic temperature of the corresponding small area of ​​this temperature group;

[0017] If the temperature of a newly added region does not meet the criteria for the current characteristic temperature, the next characteristic temperature will be calculated.

[0018] Preferably, the temperature control of the feed channel based on the characteristic temperature includes:

[0019] Small areas marked with the same characteristic temperature are divided into the same characteristic region; the heating area is then divided into regions based on each characteristic region;

[0020] The system identifies feature regions whose characteristic temperatures are lower than or equal to the protection temperature in real time, and dynamically heats the preceding feature region of the feature region; wherein, the protection temperature is the minimum temperature in the material channel that ensures glass quality.

[0021] Preferably, the dynamic heating includes:

[0022] Obtain the material channel distance between adjacent heating feature areas and sort them according to the size of the material channel distance to obtain a sequence list; extract the material channel distances in the sequence list in turn, and determine whether the absolute value of the difference between the material channel distance and the mode of the material channel distance in the sequence list exceeds a set threshold; if yes, delete the material channel distance; if no, retain the material channel distance; when the material channel distance extraction is completed, calculate the average value of the retained material channel distances and mark the average value as the cooling distance;

[0023] Determine whether the distance between the currently heated feature area and the material channel outlet exceeds the cooling distance; if yes, heat the feature area to the limit temperature; if no, obtain the temperature value ZW that the current area needs to increase based on the formula ZW=(DW-BW)×S / JD; where DW is the limit temperature, BW is the protection temperature, S is the distance between the currently heated feature area and the material channel outlet, and JD is the cooling distance.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention divides the feed channel into a natural cooling zone and a heating zone. In the natural cooling zone, the glass is naturally cooled to a suitable temperature range, and then dynamically heated in the heating zone. This helps save energy and improves economic efficiency.

[0026] 2. In the process of obtaining characteristic temperature through regional temperature, when the temperature of a newly added region meets the characteristic temperature judgment, it indicates that the temperature of that region is close to that of the previous few regions. These regions can be grouped into the same region for temperature adjustment. This reduces the operating frequency of the heater and improves the working efficiency of the system.

[0027] 3. This invention establishes dynamic heating, identifying characteristic temperatures in the heating area that are lower than or equal to the protection temperature, and the corresponding locations of these characteristic areas. When the material channel distance between the currently heated characteristic area and the material channel outlet exceeds the cooling distance, it proves that the area can be heated to the specified temperature without wasting energy; when the material channel distance between the currently heated characteristic area and the material channel outlet is less than the cooling distance, the required temperature increase can be calculated using a formula. Through this dynamic heating, corresponding heating modes can be implemented for the heating area, reducing the system's energy consumption. Attached Figure Description

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0031] Figure 3 This is a schematic diagram of the dynamic heating operation of the present invention. Detailed Implementation

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-3 The first aspect of the present invention provides a temperature control system for a glass melt flow channel, comprising: a region planning module, and a temperature control module and a database connected thereto;

[0034] The zone planning module is used to divide the material channel into several small zones. Temperature sensors collect the temperature of each small zone, and the material channel is dynamically planned based on the set temperature to obtain the control zone. The set temperature refers to the maximum temperature that the material channel needs to maintain glass quality, which is set through experience. The control zone includes a natural cooling zone and a heating zone.

[0035] Temperature control module: used to acquire the temperature of each small area in the heating zone of the control area, mark the temperature of each small area in the heating zone as the area temperature, process the area temperature to obtain the characteristic temperature, and control the temperature of the material channel based on the characteristic temperature;

[0036] Database: Used to store data.

[0037] It should be noted that dividing the material channel into several small areas includes equal material channel spacing and key point spacing. Among them, equal material channel spacing: the material channel is divided into small areas with equal distances based on the average diameter or average spacing of the material channel. This method is usually suitable for situations where the diameter or spacing of the material channel is relatively uniform, and it is convenient to calculate the size and number of each small area.

[0038] Key point segmentation includes the inlet and outlet of the feed channel, bends and forks in the feed channel, support points in the feed channel, and the location of the check valve. Key point segmentation is applicable to irregularly shaped feed channels, capturing the characteristics of their irregular shape for better segmentation of smaller areas; it more accurately reflects the actual structure of the feed channel, thus improving segmentation precision; and different key points can be selected for segmentation according to actual needs and circumstances, increasing the flexibility of segmentation.

[0039] In this application, the control zone is obtained by dynamically planning the material channel based on a defined temperature, including:

[0040] The first small area at a defined temperature is obtained by a temperature sensor and marked as the defined area; the area before the defined area is marked as the natural cooling area, and the area after the defined area is marked as the heating area. The information of the natural cooling area and the heating area is stored in a database.

[0041] It is worth noting that the melting temperature of glass wool raw materials is approximately between 1310-1350℃, while the temperature of the feed channel needs to be maintained between approximately 1030-1080℃. Therefore, a certain range of natural cooling zone can be established in the section before the feed channel. Thus, this invention establishes a defined zone, identifying the first small area at the defined temperature and marking it as the defined zone. The defined zone established in this invention is dynamically changing; its position is determined based on the current glass temperature. Changes in the glass temperature will also cause changes in the defined zone. The area before the defined zone can serve as a natural cooling zone, which does not require artificial heating.

[0042] In this application, the characteristic temperature is obtained by processing the regional temperature, including:

[0043] The small areas within the heating zone are sorted and a sorting table is created. The area temperatures are extracted sequentially from the sorting table and added to the feature temperature determination to obtain the feature temperature. The sorting method prioritizes areas closer to the material channel, with the material channel distance calculated along the material channel.

[0044] The characteristic temperature determination in this application includes:

[0045] Extract the regional temperature and establish a temperature group based on the extracted regional temperature; obtain the variance of the regional temperature group and determine whether the variance is less than a set value; if yes, add the new regional temperature and re-determine the feature temperature; where the set value is obtained through experience, and the new regional temperature refers to the temperature of the next regional temperature.

[0046] No, mark the temperature of this area as not meeting the criteria for this characteristic temperature judgment, and mark the average of this temperature group as the same characteristic temperature of the corresponding small area of ​​this temperature group;

[0047] If the temperature of a newly added region does not meet the criteria for the current characteristic temperature, the next characteristic temperature will be calculated.

[0048] It is worth noting that this step obtains the characteristic temperature through the regional temperature. When the temperature of a newly added region meets the characteristic temperature judgment, it indicates that the temperature of this region is close to that of the previous few regions. These regions can be grouped into the same region for temperature adjustment. This reduces the operating frequency of the heater and improves the working efficiency of the system.

[0049] It should be noted that in the characteristic temperature judgment, when a newly added area temperature meets the characteristic temperature judgment, the next area temperature will be added and the characteristic temperature judgment will be performed again until the added area temperature does not meet the characteristic temperature judgment. Then, the area temperature that meets the characteristic temperature judgment before the added area temperature will be marked as the same characteristic temperature.

[0050] This application includes temperature control of the material channel based on characteristic temperature, including:

[0051] Small areas marked with the same characteristic temperature are divided into the same characteristic region; the heating area is then divided into regions based on each characteristic region;

[0052] The system identifies feature regions whose characteristic temperatures are lower than or equal to the protection temperature in real time, and dynamically heats the preceding feature region. The protection temperature is the minimum temperature in the material channel that ensures glass quality.

[0053] It is worth noting that this step obtains the characteristic region through the characteristic temperature. In the subsequent heating, different characteristic regions are heated at intervals, which reduces the energy consumption of the system while improving the heating efficiency.

[0054] Dynamic heating is performed in this application, including:

[0055] Obtain the material channel distance between adjacent heated feature areas and sort them according to the size of the material channel distance to obtain a sequence list; extract the material channel distances in the sequence list one by one, and determine whether the absolute value of the difference between the material channel distance and the mode of the material channel distance in the sequence list exceeds a set threshold; if yes, delete the material channel distance; if no, keep the material channel distance; when the material channel distance extraction is completed, calculate the average value of the retained material channel distances and mark the average value as the cooling distance;

[0056] Determine whether the distance between the currently heated feature area and the material channel outlet exceeds the cooling distance; if yes, heat the feature area to the limit temperature; if no, obtain the temperature value ZW that the current area needs to increase based on the formula ZW=(DW-BW)×S / JD; where DW is the limit temperature, BW is the protection temperature, S is the distance between the currently heated feature area and the material channel outlet, and JD is the cooling distance.

[0057] It is worth noting that the dynamic heating in this step refers to identifying the characteristic temperatures in the heating area that are lower than or equal to the protection temperature, and the corresponding locations of these characteristic areas. When the material channel distance between the currently heated characteristic area and the material channel outlet exceeds the cooling distance, it proves that the area can be heated to the specified temperature without wasting energy; when the material channel distance between the currently heated characteristic area and the material channel outlet is less than the cooling distance, the required temperature increase can be calculated using a formula. Through such dynamic heating, appropriate heating modes can be implemented for the heating area, thereby reducing the system's energy consumption.

[0058] Some of the data in the above formula are calculated by removing dimensions and taking their numerical values. The formula is the closest to the real situation obtained by software simulation of a large amount of collected data. The preset parameters and preset thresholds in the formula are set by those skilled in the art according to the actual situation or obtained through simulation of a large amount of data.

[0059] Working principle of the invention:

[0060] The material channel is divided into several small areas. Temperature sensors collect the temperature of each small area, and dynamic planning is performed on the material channel based on the defined temperature to obtain the control area. The temperature of each small area in the heating zone of the control area is obtained and marked as the area temperature. The small areas in the heating zone are sorted and a sorting table is established. The area temperatures are extracted sequentially from the sorting table and added to the characteristic temperature judgment. When the temperature of a newly added area does not meet the characteristic temperature judgment, the area temperature before that small area is marked as the same characteristic temperature, and the next characteristic temperature is calculated. Small areas with the same characteristic temperature are divided into the same characteristic area. The heating area is divided into regions based on each characteristic area. Characteristic areas with characteristic temperatures lower than or equal to the protection temperature are identified in real time, and the preceding characteristic area of ​​the characteristic area is dynamically heated.

[0061] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
