Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass production, and particularly relates to an automatic regulating device for synchrotron glass and mixed materials. Background Art

[0002] In the production process of photovoltaic glass, batching is one of the most important processes, among which the synchronization accuracy of the transportation of broken glass and mixed materials to the furnace head silo is an important indicator. Various raw materials required for glass production are automatically weighed by electronic scales and transported to the mixer by a collective belt conveyor. After a certain period of mixing, humidity adjustment and temperature adjustment in the mixer, the various raw materials are called mixed materials. The finished mixed materials are discharged into the buffer bin at the bottom of the mixer and the tail of the raw melt conveyor belt, and are transported to the furnace head silo (the terminal station for batching) by the raw melt conveyor belt.

[0003] Another important raw material for glass production, cullet, has been added to the cullet electronic scale bucket by the cullet electronic scale feeder according to the quantity requirements before the mixture enters the buffer bin. When the mixture leaves the buffer bin, the cullet is discharged from the cullet scale bucket by the cullet discharger a few seconds in advance or lag, and is transported to the intersection of the cullet conveyor belt and the original melt conveyor belt by the cullet conveyor belt machine, and sprinkled on the mixture on the original melt conveyor belt. By adjusting the advance or lag time of cullet discharge, it is ensured that the cullet and the mixture arrive at the intersection of the cullet conveyor belt and the original melt conveyor belt at the same time. The length of the belt conveyor is fixed, and the running speed is also fixed. After adjustment, there will be basically no change. The ideal state required by the process is that the cullet and the mixture are completely synchronized, that is, the cullet is completely sprinkled on the mixture, and when the tail of the mixture passes the intersection, the cullet also enters completely, and there is no trailing of cullet or mixture.

[0004] However, since factors such as the humidity, temperature, and season of the mixture will affect the discharge time of the mixture from the buffer bin, the humidity, particle size, and state of the cullet discharger of the broken glass will also affect the discharge speed of the broken glass. In order to ensure synchronization, the usual practice is for the batching operator to observe the state of the tail of the material layer through the camera above the intersection. If the mixture is tailing (the mixture takes a long time to discharge), the discharge speed of the cullet discharger will be appropriately reduced. If the cullet is tailing (the cullet takes a long time to discharge), the discharge speed of the cullet discharger will be appropriately increased. However, if it relies entirely on manual operation, there will be many human factors that lead to less than ideal synchronization. Summary of the invention

[0035] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0036] The utility model provides an automatic regulating device for synchro-nizing broken glass and mixed materials, such as Figures 1 to 7 shown.

[0037] A device for automatically adjusting the synchronization of cullet and mixed material comprises a cullet conveying device, a mixed material conveying device and a monitoring and control device 4. The cullet conveying device comprises a cullet bin 8, a cullet discharger 6 which is controllably connected to the cullet bin 8, and a cullet conveyor belt 1 arranged below the cullet discharger 6. In order to achieve precise control of the discharge, a cullet electronic scale 5 is also arranged between the cullet bin 8 and the cullet discharger 6.

[0038] The mixed material conveying device comprises a mixed material buffer bin 7 and a raw melt conveying belt 2 connected thereto;

[0039] The monitoring and control device 4 includes a video acquisition system, a comparison operation system and a digital-to-analog conversion system, and the video acquisition system is located above the intersection of the cullet conveyor belt 1 and the raw melt conveyor belt 2 and is connected to the digital-to-analog conversion system signal through the comparison operation system. The digital-to-analog conversion system converts the conversion result into a standard analog quantity (4-20mA) and sends it to the batching control system, and the batching control system drives the cullet discharger 6 to adjust the discharge speed of the cullet to the cullet conveyor belt 1 to achieve synchronization of the cullet and the mixed material.

[0040] The video acquisition system includes a high-definition digital camera, an image recognition system connected thereto, and a classified sample video for comparison, and the image recognition system and the classified sample video are input into the comparison operation system for comparison. In this embodiment, a high-definition digital camera is installed above the intersection of the raw melt conveyor belt 2 and the cullet conveyor belt 1 to collect and record the coverage of the cullet on the mixed material and input it into the video comparison operation server computer.

[0041] The proportion states of the cullet and the tail of the mixture collected by the classified sample video include mixture state B, blending state A and cullet state C; among them, mixture state B is all mixture; blending state A is that the cullet covers the mixture; and cullet state C is all cullet.

[0042] The batching control system controls the discharging speed of the broken glass discharging machine and converts the signal into a 4-20mA standard current signal through a digital-to-analog conversion system and transmits it to the analog input module of the batching control system.

[0043] The operator manually specifies the start sampling screen and the end sampling screen on the server computer. When the system is in the automatic state, it automatically starts sampling and recording (starts recording) when the sampling screen is reached, and automatically ends sampling recording (ends recording) when the end sampling screen is reached. In this embodiment, the server computer manually specifies that video acquisition starts when there is material on the belt and stops when there is no material on the belt. After the system self-learns, in the automatic state, video acquisition automatically starts when there is material on the belt and automatically stops when there is no material on the belt.

[0044] During the collection process, the sample videos of three states, namely, mixed material state B, compounded state A and broken glass state C, are compared second by second, and 1 is added to the corresponding cumulative timer. The compounded state is used to monitor the discharge and is often not used to adjust the discharge speed. When the mixed material state and broken glass state are less than 5 seconds, it is considered to be a controlled state and the broken glass discharge speed is not adjusted.

[0045] When the mixed material state or the broken glass state is less than 5 seconds, it is in a controlled state, and the discharge speed of the broken glass discharge machine is not adjusted;

[0046] When the mixed material state is greater than 5 seconds and less than 10 seconds, the discharge speed of the broken glass discharge machine is reduced by 0.5%.

[0047] When the mixed material state is greater than 10 seconds and less than 20 seconds, the discharge speed of the broken glass discharge machine is reduced by 1%.

[0048] When the mixed material state is greater than 20 seconds, the discharge speed of the broken glass discharge machine is reduced by 1.5%;

[0049] When the broken glass state is greater than 5 seconds and less than 10 seconds, the discharge speed of the broken glass discharge machine is increased by 0.5%;

[0050] When the broken glass state is greater than 10 seconds and less than 20 seconds, the discharge speed of the broken glass discharge machine is increased by 1%;

[0051] When the broken glass state is greater than 20 seconds, the discharge speed of the broken glass discharge machine increases by 1.5%.

[0052] The initial discharge speed (percentage) of the cullet discharger can be manually input on the server and can be changed at any time according to the actual working conditions; under normal circumstances, the mixed material state and the cullet state will not appear at the same time in the same auxiliary material.

[0053] The final discharge speed value of the cullet discharger calculated by the server computer is converted into a 4-20mA standard current signal through the digital-to-analog conversion module and transmitted to the analog input module of the batching control system. The batching control system controls the discharge speed of the next batch of cullet discharger based on this value.
