Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pickling equipment, in particular to a pickling basket for square silicon cores. Background Art
[0002] The silicon core beam (also called beam) is a kind of silicon core, which is a square silicon core. When pickling the beam, the beam is placed with the corners facing up on the toothed silicon core bracket in the long frame. The toothed bracket ensures that the silicon core is arranged at a fixed spacing and can be stacked up to 3 layers. The toothed bracket adopts 90° teeth to facilitate the fixing of the beam. The bracket is designed in a symmetrical form. When the beams are arranged, the beams between the upper and lower layers correspond to each other. During cleaning, the following disadvantages occur: 1. The beams are stacked at equal intervals. The number of beams placed is limited by the length of the long frame. The number of beams placed in a single frame is 3 layers, with 11 beams of 300mm in length on each layer. The number of beams placed in a single frame is 33. The long frame can place 7 sections in total, with a total of 231 beams. The gap between the beams is large when they are placed, resulting in fewer; 2. The bracket tooth shape is 90°, which is consistent with the angle of the beam and fits tightly. In the acid corrosion process, the acid enters less at the contact position between the bracket teeth and the beam, and the corrosion is lighter, resulting in inconsistent surface quality of the silicon core. Utility Model Content
[0003] The utility model aims to overcome the deficiencies in the prior art and provide a pickling flower basket which can reduce the contact area between the crossbeam and the bracket and improve the working efficiency.
[0004] The utility model is realized through the following technical scheme: a crossbeam pickling basket comprises a support frame, support plates are arranged on both sides of the support frame, and through holes for penetrating silicon cores are arranged on the two support plates.
[0005] Furthermore, each of the support plates is provided with a plurality of rows of through holes, and two adjacent rows of through holes are staggeredly distributed.
[0006] Furthermore, the support frame comprises a bottom plate, positioning frames are provided at both ends of the bottom plate, and the two support plates are detachably connected to the positioning frames.
[0007] Furthermore, the support plate comprises a base plate, both ends of the base plate are provided with plugging ridges, and the side walls of the positioning frame are provided with plugging grooves corresponding to the positions of the plugging ridges.
[0008] Furthermore, the support plate is composed of a plurality of splicing plates, a row of through holes is arranged on the side wall of each splicing plate, and an error-proofing component is arranged on each splicing plate.
[0009] Furthermore, the error-proofing component includes positioning posts arranged on the bottom surface of the splicing plate and positioning holes arranged on the top surface of the splicing plate.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example 1
[0019] like Figure 1-4 As shown, a crossbeam pickling basket comprises a supporting frame 1, supporting plates 2 are installed on both sides of the supporting frame 1, and through holes 3 for penetrating silicon cores are opened on the two supporting plates 2. The through holes are preferably circular holes. After the silicon core is penetrated, the two side edges of the silicon core are in point contact, and the silicon core is penetrated into the through holes 3 corresponding to two positions. At this time, only the prisms of the silicon core are in point contact with the side walls of the through holes 3. Compared with the direct contact between the existing toothed bracket and the surface of the silicon core, the contact area between the silicon core and the bracket can be effectively reduced. During pickling, the acid liquid corrodes the surface of the other silicon core more evenly and thoroughly, and the surface impurities are better removed, thereby improving the pickling effect.
[0020] Each support plate 2 is provided with multiple rows of through holes 3, and two adjacent rows of through holes 3 are staggered. The staggered through holes 3 can effectively utilize the space of the support plate 2, increase the number of holes, and load more silicon cores. Compared with the existing tooth-shaped bracket, the distance between two adjacent rows of silicon cores is smaller, and more silicon cores can be placed for pickling.
[0021] The supporting frame 1 includes a base plate 4, and positioning frames 5 are installed at both ends of the base plate 4. The positioning frame 5 is an inverted U-shape, and two columns are provided on both sides for fixing the supporting plate 2. A cross bar is provided at the upper end of the two columns for hanging the entire pickling flower basket. The two supporting plates 2 are detachably connected to the positioning frame 5. The detachable support plate 2 is convenient for replacement and maintenance, and can be quickly disassembled and replaced when the through hole 3 is deformed.
[0022] The support plate 2 includes a base plate 6, both ends of which are provided with plug-in ridges 7. The side walls of the positioning frame 5 are provided with plug-in grooves 8 corresponding to the positions of the plug-in ridges 7. During installation, the plug-in ridges 7 are inserted into the plug-in grooves 8 from top to bottom. The plug-in grooves 8 are T-shaped grooves. The inner side walls of the T-shaped grooves are provided with rubber pads that fit the plug-in ridges 7. There are multiple rubber pads that are evenly distributed along the length direction of the plug-in grooves 8. After the plug-in ridges 7 are inserted into the plug-in grooves 8, the rubber pads are squeezed to deform, thereby filling the gap between the two, so that the installed support plate 2 is more stable.
[0023] The support plate 2 is composed of multiple splicing plates, each of which is provided with a row of through holes 3 on the side wall, and each of which is provided with an anti-error component. The function of the anti-error component is to avoid the through holes 3 on two adjacent splicing plates being arranged in the same manner, disrupting the staggered layout of the through holes 3, and ultimately affecting the number of silicon cores that the entire pickling basket can accommodate. The spliced support plate 2 can place the silicon cores layer by layer in the pickling basket, reducing the time taken by the pickling basket to increase the silicon core capacity.
[0024] The error-proofing component includes a positioning column 9 located on the bottom surface of the splicing plate and a positioning hole 10 located on the top surface of the splicing plate. The positioning holes 10 and the positioning columns 9 on each splicing plate are staggered. The positioning columns 9 and the positioning holes 10 of two adjacent splicing plates are used in conjunction with each other. The positioning column 9 of the upper splicing plate is inserted into the positioning hole 10 on the top of the next splicing plate.
[0025] When in use, the pickling basket is 660mm long, about 1 / 5 of the length of the long frame, 200mm wide, less than the width of the long frame, and the height is the same as the height of the original pickling basket. The specification of the placed beam is 18*18 (mm). Round holes are opened on the protective side panels. The round holes can reduce the contact area between the beam and the side panels and improve the pickling effect. The left and right spacing of the holes is about 5mm, the upper and lower spacing is 5mm, and the upper and lower holes are staggered by 1 / 2 of the hole position. There are 5 layers of holes, 17 holes in each layer, and a total of 85 holes. The hole diameter is 26mm, slightly larger than the diagonal length of the beam. A single pickling basket can hold 85 beams. Five improved pickling baskets can be placed in each long frame, that is, a total of 425 beams. The original pickling basket can hold five in the long frame, and 231 beams can be placed in each pickling basket. The improved pickling basket can increase the capacity of the entire long frame by about 50%, which can significantly improve production efficiency.
[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
