TECHNICAL FIELD

[0001] The application relates to the technical field of iron removal devices for photovoltaic glass, and in particular to an iron removal device for photovoltaic glass raw materials. BACKGROUND

[0002] Photovoltaic glass is a kind of super-transparent low-iron glass, and light transmittance is the most critical index, directly affecting the photovoltaic conversion rate of the assembly. The existence of iron causes the glass to produce color, which reduces the transparency and light transmittance of the glass. Therefore, in the production of photovoltaic glass, the iron content needs to be strictly controlled, and in particular, the control of iron in the batching process of raw materials is very important. The conventional way is to use a magnetic grid or a belt iron remover (for example, CN102503075A, CN213865897U, etc.) to absorb iron to reduce the iron content. However, the raw materials also need to pass through multiple metal chute pipes during the batching process, which will also produce iron impurities, thereby causing the iron content of the raw materials to increase, and further affecting the light transmittance and transparency of the photovoltaic glass.

[0029] Techniques, methods and equipment known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be considered as part of the specification.

[0030] AsFigure 1 As shown, the embodiment of the present application provides a kind of photovoltaic glass raw material iron removal device, including: outer tube 1, flange 2, inner tube 5 and permanent magnet 10;Wherein, inner tube 5 is built into outer tube 1, space is formed between inner tube 5 and outer tube 1, so that photovoltaic glass raw material flows through space;Permanent magnet 10 is built into inner tube 5;Outer tube 1 is equipped with flange 2, to connect the chute pipe for conveying photovoltaic glass raw material.

[0031] In the embodiment, at least one application can be installed in the chute pipe (middle part, tail part of chute pipe) for dispensing photovoltaic glass raw material through flange 2, so that the photovoltaic glass raw material in the chute pipe is adsorbed on the outer wall of the inner tube 5 due to the magnetic attraction of the permanent magnet 10 inside the inner tube 5 when flowing through the space between the inner tube 5 and the outer tube 1 of the application, thereby reducing the iron content in the photovoltaic glass raw material, and further improving the light transmittance and transparency of the photovoltaic glass. In actual application, one or two flanges 2 can be provided, and the flange 2 and the outer tube 1 can be concentrically arranged or eccentrically arranged, and the flange 2 can be arranged on the end and / or side wall of the outer tube 1, which is specifically arranged corresponding to the photovoltaic glass raw material conveying path.

[0032] As shown in Figure 1 In some embodiments, the permanent magnet 10 is detachably mounted in the inner tube 5. In the embodiment, when it is needed to remove the iron adsorbed on the outer wall of the inner tube 5, the permanent magnet 10 is only needed to be taken out from the inner tube 5, and the iron adsorbed on the outer wall of the inner tube 5 will fall off due to the loss of magnetic attraction, thereby ensuring the iron removal efficiency of the application.

[0033] As shown in Figure 1 In some embodiments, the inner tube 5 includes a first shell and a second shell, wherein the first shell and the second shell jointly form a containing space for placing the permanent magnet 10, and the first shell and the second shell are detachably connected. In the embodiment, the first shell and the second shell can both be cavities, or one of them can be a cavity and the other can be a flat plate, and they can be detachably connected by buckling, inserting or bolting 6. At least one of the first shell and the second shell forms a space for containing the permanent magnet 10, thereby facilitating the taking and placing of the permanent magnet 10.

[0034] As shown in Figure 1 In some embodiments, the first shell and the second shell are connected by the bolt 6. In the embodiment, the first shell and the second shell are more reliable and convenient to disassemble by connecting through the bolt 6, which is low in cost and easy to implement. In order to improve the connection reliability of the first shell and the second shell, the bolt 6 is preferably arranged at a position not in contact with the photovoltaic glass raw material, so as to protect the bolt 6 from being damaged or loosened due to the scouring of the photovoltaic glass raw material.

[0035] As shown in Figure 1As shown, in some embodiments, the permanent magnet 10 is covered with a protective layer. The protective layer facilitates the placement and removal of the permanent magnet 10, protects it, and extends its service life, thereby reducing the cost of use in this application. In practical applications, the protective layer can be a film layer plated on the permanent magnet 10, or a shell layer wrapped around the outside of the permanent magnet 10. The protective layer can be a metal layer, an alloy layer, or an organic film layer, such as a stainless steel shell, an aluminum shell, or a plastic shell.

[0036] like Figure 1 As shown, in some embodiments, the inner cylinder 5 gradually widens along the flow direction of the photovoltaic glass raw material. The dimension of the inner cylinder 5 near the side flowing from the chute towards itself is smaller than the dimension of the side flowing out of itself, so that the photovoltaic glass raw material will not accumulate in the inner cylinder 5, making it less likely to cause blockage and ensuring the smooth flow of the photovoltaic glass raw material through this application. Exemplarily, the outer cylinder 1 is a cylindrical structure with flanges 2 at both ends. One flange 2 is connected to the upstream chute, and the other flange 2 is connected to the downstream chute. Thus, the photovoltaic glass raw material flows sequentially through the upstream chute, this application, and the downstream chute along its flow direction. The side of the inner cylinder 5 near the upstream chute has a conical structure, and the side of the inner cylinder 5 near the downstream chute has a cylindrical structure, with the apex of the conical structure closest to the upstream chute. Of course, in other embodiments, the inner cylinder 5 can be a spherical structure, a multi-faceted spherical structure, or a structure with an upper cone and a lower prism, etc. This application does not limit its shape and structure, as long as the photovoltaic glass raw material can pass through this application smoothly.

[0037] like Figure 1 As shown, in some embodiments, the inner cylinder 5 is provided with a wear-resistant portion. In this embodiment, the wear-resistant portion can extend the service life of the inner cylinder 5, thereby reducing the usage cost of this application. Specifically, the inner cylinder 5 can be either a wear-resistant cylinder or have a wear-resistant layer on its surface. Of course, to save costs, the inner cylinder 5 may only have a wear-resistant portion partially provided, for example, only at the position in contact with the photovoltaic glass raw material, or only on the side near the upstream chute.

[0038] like Figure 1As shown in the drawings, in some embodiments, the inner cylinder 5 is suspended inside the outer cylinder 1 by a support arm 9 connected to the outer cylinder 1. In this embodiment, the inner cylinder 5 is installed by the support arm 9 installed on the outer cylinder 1, and the structure is stable and reliable. The support arm 9 can be radially arranged on the inner wall of the outer cylinder 1. It can also be arranged opposite to the inner wall of the outer cylinder 1 to hold the two ends of the inner cylinder 5. Of course, in other embodiments, the outer cylinder 1 can also be installed with the inner cylinder 5 through the concave-convex matching between the two, such as the inner cylinder 5 being provided with a cantilever, and the outer cylinder 1 being concave or convex inside to form a containing groove for supporting the cantilever, so that the cantilever is supported on the bottom surface of the containing groove, and the matching installation of the inner cylinder 5 and the outer cylinder 1 can be realized. Of course, the end of the outer cylinder 1 close to the downstream chute can also be provided with a variable diameter structure, that is, the closer to the downstream chute, the smaller the inner diameter size, so that the outer diameter size of the inner cylinder 5 is greater than the minimum size of the outer cylinder 1, and the outer wall surface of the inner cylinder 5 is concave with a strip-shaped groove, so as to realize the support of the inner cylinder 5 on the variable diameter structure of the outer cylinder 1, but the photovoltaic glass raw materials can flow to the downstream chute through the space between the strip-shaped groove and the outer cylinder 1.

[0039] As shown in the drawings, Figure 1 In some embodiments, the inner diameter size of the outer cylinder 1 is 2-3 times the inner diameter size of the chute. In this embodiment, in order to ensure the smoothness of the photovoltaic glass raw materials passing through the present application, the inner diameter size of the outer cylinder 1 is greater than the inner diameter size of the chute, so that the photovoltaic glass raw materials flowing out of the upstream chute flow more smoothly through the space between the inner cylinder 5 and the outer cylinder 1, and the phenomenon of insufficient supply caused by blocking of the materials will not occur. Of course, in actual application, the inner diameter size of the outer cylinder 1 can be 4, 5, 6 times the inner diameter size of the chute, and the specific value is subject to actual demand, which is not limited by the present application.

[0040] As shown in the drawings, Figure 1 In some embodiments, the outer cylinder 1 is provided with a door 3 for taking and placing the inner cylinder 5. In this embodiment, the inner cylinder 5 can be quickly taken out for replacement or removal of the iron adsorbed thereon through the opening of the door 3, which simplifies the installation, maintenance and operation of the present application.

[0041] As shown in the drawings, Figure 1 In some embodiments, the outer cylinder 1 is provided with a door hole, one side of the door 3 is hinged to one side of the door hole through a hinge 7, and the other side of the door 3 is closed or exposed to the door hole through a lock catch 4. The lock catch 4 is installed on the outer side wall of the outer cylinder 1. In this embodiment, the hinge 7 can ensure that the door 3 will not be separated from the outer cylinder 1 when taking and placing the inner cylinder 5, and the lock catch 4 can realize the quick opening and closing of the door 3, which is simple in structure and strong in practicality. Of course, in other embodiments, the door 3 can also be installed on the outer cylinder 1 through the lock catch 4, so that the door 3 will be separated from the outer cylinder 1 when taking and placing the inner cylinder 5. In other embodiments, the door 3 can also be installed on the outer cylinder 1 in the form of insertion, that is, the outer wall of the outer cylinder 1 is provided with an installation beam provided with an insertion slot, and the lower part is provided with a support beam for supporting the door 3. When the door 3 passes through the insertion slot, the bottom will be supported on the support beam, thereby realizing the closure of the door hole.

[0042] like Figure 1 As shown, in some embodiments, a sealing strip 8 is provided at the contact point between the doorway and the door 3. In this embodiment, the sealing strip 8 ensures the sealing between the doorway and the door 3, as well as the flexible contact between the door 3 and the outer cylinder 1, preventing the photovoltaic glass raw material from leaking out when the door 3 closes the doorway, thereby avoiding waste of photovoltaic glass raw material and saving costs. It is worth noting that when the door 3 is in contact with the inner wall of the doorway, the sealing strip 8 can be provided on the inner wall of the doorway and / or the outer peripheral side wall of the door 3. When the door 3 is in contact with the outer wall surface of the outer cylinder 1 near the doorway, the sealing strip 8 can be provided on the outer peripheral side of the surface of the door 3 near the doorway and / or the outer cylinder 1 can be surrounded on the outer wall surface of the doorway.
