[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 A device for filtering impurities in photovoltaic silver paste includes a filter tank 1, a lid 2 hinged to the filter tank 1, two fixing plates 3 fixedly connected to the lid 2, a fixing mechanism for fixing the lid 2 fixedly connected to the filter tank 1, a detachable filter mechanism inside the filter tank 1, the filter tank 1 being divided into a filter chamber and a storage chamber by the filter mechanism, a stirring mechanism 1 installed in the storage chamber, a fixing seat fixedly connected to the upper end of the stirring mechanism 1, a stirring mechanism 2 detachably connected to the fixing seat, the stirring mechanism 2 and the fixing seat being fixed by a hexagonal nut 4, and a pressurizing component for pressurizing the filter tank 1 by inflating air onto the surface of the lid 2.

[0022] The device for filtering impurities in photovoltaic silver paste in this utility model is structurally similar to existing filtration equipment for photovoltaic silver paste processing. For example, patent CN216755638U discloses a filtration device for photovoltaic silver paste processing. The main improvement of this utility model is that by pressurizing the inside of the filter tank 1, the filtration process of the photovoltaic silver paste is accelerated, and the contact time between the photovoltaic silver paste and air is reduced. Figures 1 to 3As shown, in use, the photovoltaic silver paste filtration device of this utility model feeds the photovoltaic silver paste into the filter tank 1 through the feed pipe on the tank cover 2. The photovoltaic silver paste falls onto the filter plate 13 and accumulates there, thus filtering the photovoltaic silver paste. During the filtration process, the driver 15 is driven, which causes the rotating shaft 16 to rotate, thereby causing the stirring blade 17 and the stirring plate 23 to rotate, stirring the photovoltaic silver paste above the filter plate 13 and making it flow, thus accelerating the filtration process. The filtered photovoltaic silver paste will also be more evenly mixed with various components under the stirring of the stirring blade 17, thus improving the quality of the photovoltaic silver paste. Furthermore, during the filtration of the photovoltaic silver paste, the air pump 25 can be started to inflate the filter tank 1. Since the photovoltaic silver paste accumulates to a certain thickness on the filter plate 13, the upper end of the filter plate 13 is sealed, thus increasing the pressure during the inflation process, thereby promoting the filtration process of the photovoltaic silver paste and reducing the filtration time.

[0023] like Figure 3 As shown, the fixing mechanism includes two rotating plates 5 fixedly connected to the filter tank 1, a rotating shaft 6 rotatably connected between the two rotating plates 5, a threaded rod 7 fixedly connected to the rotating shaft 6, an internally threaded tube 8 threadedly connected to the threaded rod 7, and a pressing plate 9 fixedly connected to the upper end of the internally threaded tube 8.

[0024] Specifically, rotating the extrusion plate 9 causes the internal threaded tube 8 to rotate, which in turn moves the extrusion plate 9 upward, gradually moving it away from the two fixing plates 3 on the can lid 2. Then, rotating the extrusion plate 9 downward releases the fixing plates 3 and the can lid 2, allowing the can lid 2 to be opened for cleaning the inside of the filter can 1.

[0025] like Figure 2 As shown, the filtration mechanism includes a support frame 10 that abuts against the upper end of the filter tank 1. Handles 11 are provided on both sides of the support frame 10. A cylindrical barrel 12 is fixedly connected to the lower surface of the support frame 10. The bottom surface of the cylindrical barrel 12 is a filter plate 13. A cylindrical tube 14 is fixedly connected to the middle part of the filter plate 13. Sealing gaskets 24 are fixedly connected to both the upper and lower surfaces of the support frame 10.

[0026] Specifically, the photovoltaic silver paste is fed into the filter tank 1 through the feed pipe on the tank cover 2. The photovoltaic silver paste will fall onto the filter plate 13 and accumulate on the filter plate 13. Under the action of gravity, the impurities contained in the photovoltaic silver paste are filtered out.

[0027] like Figure 1 As shown, the stirring mechanism includes a driver 15 fixedly connected to the lower surface of the filter tank 1. The output end of the driver 15 is fixedly connected to a rotating shaft 16. The rotating shaft 16 is rotatably connected to the filter tank 1. Several stirring blades 17 are fixedly connected below the rotating shaft 16.

[0028] Specifically, the drive driver 15 causes the rotating shaft 16 to rotate, thereby causing the stirring blade 17 to rotate, so as to stir the photovoltaic silver paste accumulated at the bottom of the filter tank 1, so that the various components in the photovoltaic silver paste are mixed more evenly, thereby improving the quality of the photovoltaic silver paste product.

[0029] like Figure 1 As shown, the driver 15 is a variable frequency speed control motor or a continuously variable speed motor.

[0030] Specifically, the stirring speed can be adjusted according to the viscosity and volume of the photovoltaic silver paste.

[0031] like Figure 3 As shown, the fixed base includes a base plate 18 fixedly connected to the rotating shaft 16, a rectangular plate 19 fixedly connected to the base plate 18, and a threaded rod 20 fixedly connected to the upper end of the rectangular plate 19.

[0032] Specifically, the base plate 18 is used to support the second stirring mechanism, and the rectangular plate 19 is used to limit the movement of the second stirring mechanism. After the second stirring mechanism is installed on the rectangular plate 19, it can be connected to the threaded rod 20 using the hexagonal nut 4 to fix the second stirring mechanism.

[0033] like Figure 3 As shown, the stirring mechanism 2 includes a connecting plate 21 that is slidably connected to the rectangular plate 19. Three support rods 22 arranged in a circular array are fixedly connected to the connecting plate 21, and stirring plates 23 are fixedly connected to the lower surfaces of the three support rods 22.

[0034] Specifically, when the rotating shaft 16 rotates, the stirring plate 23 also rotates to stir the photovoltaic silver paste above the filter plate 13, making it flow and accelerating the filtration process.

[0035] like Figure 2 As shown, the pressurization assembly includes an air pump 25 fixedly connected to the can lid 2, and an exhaust pipe 26 fixedly connected to the air pump 25. The front end of the exhaust pipe 26 penetrates the lower surface of the can lid 2.

[0036] Specifically, when filtering photovoltaic silver paste, the air pump 25 can be started to fill the filter tank 1 with air. Since the photovoltaic silver paste accumulates to a certain thickness on the filter plate 13, the upper end of the filter plate 13 is sealed. As a result, the pressure will increase during the air filling process, thereby promoting the filtration process of the photovoltaic silver paste and reducing the filtration time.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
