Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silicon material recycling equipment, specifically to a silicon material recycling and transfer device. Background Technology
[0002] Different types and specifications of silicon material are generated during the crystal rod pulling and processing process, such as head material, tail material, shoulder material, edge material, square rod material, hanging polycrystalline material, and degraded material. Some of these silicon materials can be recycled. The silicon material recycling process is roughly divided into four steps: collection, transfer, cleaning and drying.
[0003] Currently, recycled silicon material is collected and transported separately through dedicated collection boxes and dedicated transfer boxes. The dedicated collection boxes are placed on the production site (such as next to the processing machine). Employees place the corresponding recycled silicon material into the dedicated collection boxes. When the dedicated collection boxes are full, they are transferred to the dedicated transfer boxes, where workers manually move the recycled silicon material piece by piece from the dedicated collection boxes to the dedicated transfer boxes. After that, it is transferred to the cleaning area. In the cleaning area, workers manually move the recycled silicon material piece by piece into the cleaning baskets. Finally, the cleaning baskets are sent to the cleaning machine to complete the cleaning and drying.
[0004] However, the above process has the following problems:
[0005] 1. Recycled silicon material needs to be manually handled twice before it can be transferred to the cleaning machine for cleaning, which is time-consuming and inefficient.
[0006] 2. During the two manual handling processes, the recycled silicon material will be bumped multiple times, resulting in some silicon material with excessively small particle size. This silicon material with excessively small particle size cannot be recycled, resulting in material waste. Furthermore, due to the bumping, the size of the recycled silicon material will also become smaller, the contact surface will increase, and the probability of contamination will also increase. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a recycled silicon material collection and transfer device to solve the problems of long processing time, low efficiency, material waste due to bumps, and increased risk of contamination caused by the need for manual handling twice before the recycled silicon material can be cleaned.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A recycled silicon material collection and transfer device, comprising:
[0010] The inner casing, without a lid but with a bottom, is used to collect recycled silicon material; and
[0011] The outer casing has casters, is open but has a bottom, and is used to carry and transport the inner casing.
[0012] The inner casing can be lifted out of the outer casing to the cleaning machine. At this time, the cleaning fluid and hot air in the cleaning machine can quickly flow in and out through the grid plate set at the bottom of the inner casing to achieve the cleaning and drying of the recycled silicon material.
[0013] In one embodiment disclosed in this application, the inner box includes a pair of short side panels, and a pair of lifting handles are provided on the outer side of each short side panel;
[0014] The outer casing has an arc-shaped groove on its upper edge that corresponds to the lifting handle. The arc-shaped groove and the lifting handle are matched to limit the movement of the inner casing on the upper edge of the outer casing.
[0015] In one embodiment disclosed in this application, the grid plate includes a plurality of parallel longitudinal bars and a plurality of parallel transverse bars;
[0016] The longitudinal and transverse bars orthogonally divide the grid plate into multiple rectangular holes with equal flow areas.
[0017] Each of the rectangular holes measures 20*20mm.
[0018] In one embodiment disclosed in this application, the longitudinal grid strip is a round rod, and the transverse grid strip is a plate strip;
[0019] The top of the slat is higher than the top of the round rod, and the thickness of the top of the slat gradually decreases upwards.
[0020] In one embodiment disclosed in this application, the inner box further includes a pair of long side plates, and each long side plate has a plurality of U-shaped supports arranged at equal intervals above the grid plate on its inner side. The bottom of each U-shaped support slopes downward from the inner side of the long side plate to avoid residual cleaning fluid.
[0021] Long strips of recycled silicon are placed in a bridging manner between each pair of U-shaped supports inside the pair of long side plates.
[0022] In one embodiment disclosed in this application, a pair of short side plates and a pair of long side plates surround the grid plate to form the inner box;
[0023] Each of the aforementioned short side plates and long side plates is provided with a number of elongated holes extending from top to bottom to allow the cleaning fluid and hot air to flow in and out.
[0024] The elongated holes are distributed at equal intervals along the corresponding short and long side plates and located above the grid plate, and the elongated holes on the long side plates are arranged at intervals with the U-shaped supports.
[0025] In one embodiment disclosed in this application, the cleaning solution is water and acid.
[0026] In one embodiment disclosed in this application, two sets of inner boxes are provided at intervals along the width direction of the outer box.
[0027] In one embodiment disclosed in this application, the casters are located at the four corners of the bottom surface of the outer casing, and they are divided into two pairs, one of which has a braking function.
[0028] In one embodiment disclosed in this application, a handrail is provided on the outer side of one end of the outer casing in the length direction;
[0029] The handrail is located above the swivel wheel with a braking function.
[0030] Compared with the prior art, the beneficial effects of this utility model are:
[0031] 1. By collecting the inner box, transferring the outer box, and lifting the inner box out of the outer box, the recycled silicon material can flow directly from the source of production to the machine for cleaning and drying. There are no intermediate handling links, which can not only save time and labor costs and improve efficiency, but also completely avoid damage from bumps during handling and reduce contact contamination.
[0032] 2. The undulating grid plates ensure linear contact between the recycled silicon material and the grid plates, forming a staggered stack. This effectively reduces the contact area between the recycled silicon material and the bottom of the inner chamber, lowers the flow resistance during cleaning fluid rinsing and hot air drying, and reduces cleaning fluid residue, which is beneficial for the rapid cleaning and drying of the recycled silicon material.
[0033] 3. Through each pair of U-shaped supports on the inner side of a pair of long side plates, the long strip of recycled silicon material can be separated from recycled silicon material of other shapes, so that it can be quickly cleaned and dried after collection.
[0034] 4. The numerous elongated holes around the perimeter increase the speed at which cleaning fluid and hot air flow into and out of the inner chamber, thereby further improving the efficiency of cleaning and drying recycled silicon material. Attached Figure Description

[0044] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.
[0045] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0046] See Figures 1-3 As shown, this utility model provides a recycled silicon material collection and transfer device, comprising:
[0047] The inner casing is 100mm, open with a bottom, and is used to collect recycled silicon material; and
[0048] The outer casing 200 has casters 210, is open-topped and has a bottom, and is used to carry and transport the inner casing 100.
[0049] The inner casing 100 can be lifted out of the outer casing 200 to the cleaning machine (not shown in the figure). At this time, the cleaning fluid and hot air in the cleaning machine can quickly flow in and out through the grid plate 110 set at the bottom of the inner casing 100 to achieve the cleaning and drying of the recycled silicon material.
[0050] Specifically, the inner box 100 includes a pair of short side plates 120, and a pair of lifting handles 121 are provided on the outer side of each short side plate 120; the upper edge of the outer box 200 has an arc-shaped groove corresponding to the lifting handles 121 (its depth is shallow, so it is completely covered by the lifting handles 121 in the figure and cannot be seen), and the arc-shaped groove and the lifting handles 121 are matched to limit the inner box 100 to rest on the upper edge of the outer box 200.
[0051] In use, the device is placed directly on the production site (e.g., next to a processing machine). Employees pick up the processed and cut recycled silicon material and put it into the inner box 100. After it is full, the outer box 200 is pushed or the device is pulled to the cleaning machine by an AGV. At this time, the inner box 100 is lifted into the inlet of the cleaning machine by hooking the lifting handle 121 with a hoisting device (e.g., a crane). The cleaning liquid in the cleaning machine flows quickly into the inner box 100 through the grid plate 110 to clean the recycled silicon material. Then, the inner box 100 is lifted again by the hoisting device so that the cleaning liquid flows quickly out of the inner box 100 through the grid plate 110. Then, the hot air in the cleaning machine is introduced into the inner box 100 to bake the cleaned recycled silicon material, thereby realizing the cleaning and drying of the recycled silicon material. In other words, by collecting the inner box 100, transferring it to the outer box 200, and lifting the inner box 100 out of the outer box 200, the recycled silicon material can flow directly from the source of production to the machine for cleaning and drying without any intermediate handling links. This not only saves time and labor costs and improves efficiency, but also completely avoids damage from bumps during handling and reduces contact contamination.
[0052] The grating plate 110 includes several parallel longitudinal bars 111 and several parallel transverse bars 112. The longitudinal bars 111 and transverse bars 112 orthogonally divide the grating plate 110 into multiple rectangular holes with equal flow areas, each rectangular hole measuring 20*20mm. This facilitates the rapid flow of cleaning fluid and hot air from the cleaning machine into and out of the inner chamber 100, while also allowing small pieces of silicon material smaller than 20*20mm to fall through the rectangular holes into the outer chamber 200 for early slag removal, thus ensuring that the screened silicon material meets the required size for reuse.
[0053] See Figure 3 As shown, the longitudinal grid bars 111 are round rods, and the transverse grid bars 112 are slats; the top of the slats is higher than the top of the round rods, and the thickness of the top of the slats gradually decreases upwards. This results in an undulating grid plate 110, allowing the recycled silicon material to make linear contact with the grid plate 110 and form a staggered stack. This effectively reduces the contact area between the recycled silicon material and the bottom of the inner casing 100, lowers the flow resistance during cleaning fluid rinsing and hot air drying, and also reduces cleaning fluid residue, facilitating rapid cleaning and drying of the recycled silicon material.
[0054] The inner casing 100 also includes a pair of long side panels 130. Each long side panel 130 has multiple U-shaped supports 131 evenly spaced above the grid plate 110 on its inner side. The bottom of each U-shaped support 131 slopes downwards from the inner side of the long side panel 130 to avoid residual cleaning fluid. Strip-shaped recycled silicon material (such as edge material) is placed in a bridging manner between each pair of U-shaped supports 131 on the inner side of the pair of long side panels 130. In this way, the strip-shaped recycled silicon material can be separated from recycled silicon material of other shapes, allowing for rapid cleaning and drying after collection.
[0055] A pair of short side plates 120 and a pair of long side plates 130 surround the grid plate 110 to form the aforementioned inner chamber 100 (specifically, each longitudinal grid bar 111 is connected between the pair of short side plates 120, and each transverse grid bar 112 is connected between the pair of long side plates 130). Each short side plate 120 and long side plate 130 has a plurality of elongated holes extending downwards to allow cleaning fluid and hot air to flow in and out. The plurality of elongated holes are evenly distributed along the corresponding short side plate 120 and long side plate 130 and are located above the grid plate 110, and the elongated holes on the long side plate 130 are spaced apart from the U-shaped support 131. In this way, the plurality of elongated holes around the perimeter can increase the speed at which cleaning fluid and hot air flow into and out of the inner chamber 100, thereby further improving the efficiency of cleaning and drying recycled silicon material.
[0056] In this embodiment, the cleaning solution is water and acid. The recycled silicon material is first rinsed with water after entering the cleaning machine, and then immersed in acid for pickling.
[0057] See Figure 1 and Figure 2 As shown, two sets of inner casing 100 are spaced apart along the width direction of outer casing 200. In this way, more recycled silicon material can be collected and transported at one time.
[0058] The casters 210 are located at the four corners of the bottom surface of the outer casing 200. They are divided into two pairs, one of which has a braking function.
[0059] A handrail 220 is provided on the outer side of one end of the outer casing 200 along its length. The handrail 220 is located above the caster wheel 210 with a braking function. In this way, it is more convenient for employees to push the device using the handrail 220. At the same time, when not pushing the device, employees can step on the brake of the caster wheel 210 below the handrail 220 to fix the device in place.
[0060] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
