At present, in the production process of solar cells, the requirements on chemicals are high, when the chemicals are abnormal in the process of operation such as canning, feeding and the like, the abnormal chemicals have great impact on the good efficiency of the production line, and the great economic loss of the production line can be caused.

At present, a chemical feeding device adopts a centralized feeding mode, and because the centralized feeding device has no purifying and filtering functions, when the chemical is abnormal in the production process, the abnormal feeding device can only be generally stopped, and the chemical in the abnormal feeding device is discharged and returned to a factory or scrapped, so that the loss is large. Meanwhile, new chemicals cannot be sent in time, so that the production line can only bear good efficiency loss caused by abnormal chemicals in order to ensure continuous output (larger production stopping loss) of the production line, and the production line has stable indexes and larger economic benefit impact on the production line.

At present, the conversion efficiency of the solar cell is higher and higher, the quality requirement on chemicals is higher and higher, and the production line abnormality caused by the chemical problem is more and more frequent. When the process product is abnormal, the difficulty in the aspects of problem investigation and abnormal locking can be caused, and when the chemicals of the whole feeding device are abnormal, the investigation period is longer, the influence time of good efficiency is longer, and the loss is larger.

In order to solve the technical problems in the prior art, as shown in fig. 1, an embodiment of the present utility model provides a feeding device, where the feeding device has a feeding end 15, and the feeding end 15 is connected to a process device for using materials, so as to realize the supply of the materials. The feeding device comprises a storage tank 1, a first pipeline 2, a first valve 3, a second pipeline 4, a second valve 5 and a purifying system 6, wherein the storage tank 1 is used for storing materials to be conveyed, and the storage tank 1 comprises a feed inlet 1.1 and a discharge outlet 1.2. The first pipeline 2 is communicated with the discharge port 1.2 and the feed end 15. The first valve 3 is disposed on the first pipeline 2 and is used for controlling on-off of the first pipeline 2. The second pipeline 4 is communicated with the discharge port 1.2 and the feed end 15. The second valve 5 is disposed on the second pipeline 4 and is used for controlling the on-off of the second pipeline 4. The purifying system 6 is disposed in the second pipeline 4 and is used for purifying the material flowing through the second pipeline 4.

Under the condition of adopting the technical scheme, materials stored in the storage tank 1 provided by the embodiment of the utility model are conveyed to the feeding end 15 through the first pipeline 2 or the second pipeline 4, the first valve 3 is used for controlling the on-off of the first pipeline 2, the second valve 5 is used for controlling the on-off of the second pipeline 4, the purifying system 6 is arranged on the second pipeline 4, and the purifying system 6 is used for purifying the materials flowing through the second pipeline 4. Under the condition that the materials are not abnormal, the second valve 5 on the second pipeline 4 can be in a closed state, and the first valve 3 on the first pipeline 2 is in an open state, so that the materials are conveyed to the feeding end 15 only through the first pipeline 2. When the material is abnormal, the first valve 3 on the first pipeline 2 can be in a closed state, and the second valve 5 on the second pipeline 4 is in an open state, so that the material passes through the second pipeline 4 and passes through the purifying system 6 arranged on the second pipeline 4, and the material is purified and then is conveyed to the feeding end 15. At the moment, on one hand, abnormal materials are not required to be discharged or even scrapped, so that the operation is simplified, the utilization rate of the materials is improved, and the waste of the materials is avoided. On the other hand, compared with the mode of using abnormal materials to ensure the continuity of the production process in the prior art, the feeding device provided by the embodiment of the utility model can quickly respond, reduces the loss caused by abnormal materials and improves the good efficiency of products. Moreover, when the production process link using the materials is abnormal, the purified materials can be conveyed to the process link in a mode of purifying the materials without stopping, at the moment, if the products using the purified materials are still in an abnormal state, the abnormal products caused by the abnormal products can be eliminated, and if the products are recovered to be normal, the abnormal products caused by the abnormal products can be locked. Therefore, abnormal conditions of materials can be eliminated or locked, the investigation period can be shortened, abnormal chemicals can be quickly recovered to be normal, good efficiency loss is reduced, and further, the production efficiency of the solar cell is improved.

In practical situations, during the process of filling the materials into the storage tank, or when the pipeline is in butt joint with the valve, the pipeline is in butt joint with the storage tank, or during the process of filling the materials while using the materials, or the materials are out of date, the abnormal phenomena of the materials can be caused. When the valve is closed or opened, the valve can be opened or closed manually by a person, and of course, the controller can also be used for intelligently controlling the opening and closing of the valve. In specific implementation, when the product produced by the production line is abnormal, and the characterization result points to the material, the first valve 3 can be quickly closed, and the second valve 5 is opened, so that the abnormal material passes through the purification system 6, the purification system 6 purifies the abnormal material, and the material is recovered to be normal, and then is conveyed to the feeding end 15, so that the feeding device provided by the embodiment of the utility model supplies normal material, and the production line is quickly recovered to be normal. So, on the one hand, the feedway can in time respond, and the unusual problem of product that causes of material is solved to the very first time. On the other hand, the production capacity, yield and efficiency loss of the production line caused by abnormal materials borne in order to ensure the production continuity can be avoided. Furthermore, the abnormal materials are not required to be discharged from the feeding device and returned to the factory, even scrapped, so that the materials are saved, and the resource investment is reduced.

When the products produced by the production line are abnormal and the abnormal materials cannot be clearly determined. At this point, the first valve 3 may be closed and the second valve 5 opened, allowing the material to pass through the purification system 6. If the product is recovered to be normal under the condition, the abnormal occurrence of the material can be confirmed. If the product is still abnormal, then it can be excluded that the abnormality of the product is caused by the abnormality of the material. Therefore, whether the material is abnormal or not can be rapidly checked.

It should be noted that in the embodiment provided in the present utility model, the material may be in a gaseous, liquid or solid state. The material can be a material applied to various technical fields, and illustratively, the material can be a chemical applied to a solar cell production process (wet process), and the feeding device provided by the embodiment of the utility model can improve the good efficiency of the solar cell, is convenient for the investigation and locking of abnormal chemicals, shortens the investigation period and enables the abnormal chemicals to be quickly recovered to be normal.

When the number of the storage tanks 1 is plural, the number of the third valves 7 is plural, and one third valve 7 corresponds to one storage tank 1. When the material stored in one storage tank 1 is used up, the third valve 7 corresponding to the storage tank 1 can be closed, and at the same time, the third valve 7 corresponding to the other storage tank 1 is opened, so that the storage tank 1 can be replaced by controlling the opening and closing of the third valve 7.

In addition, when the flow rate of the material required by the process is large, a plurality of fourth valves 10 can be simultaneously opened and corresponding first conveying pumps 9 can be started so as to increase the flow rate of the material conveyed by the feeding end.
