Technical Field

[0001] This utility model belongs to the field of solar cell technology, and specifically relates to a membrane slag recovery device. Background Technology

[0002] The film removal and re-etching process is an indispensable part of the production process. It is mainly used to remove the film on the surface of photovoltaic modules in order to carry out subsequent processing steps. A large amount of film residue with high water content will be generated during the film removal process.

[0003] In existing technologies, membrane stripping and re-etching equipment typically removes the surface adhesive film in a stripping tank. The membrane residue is then pumped through pipelines to a squeezer for compression. While this can initially remove some moisture from the membrane residue, the moisture content of the squeezed residue remains high. High moisture content in the membrane residue not only increases the cost of hazardous waste treatment but also necessitates frequent manual replacement of hazardous waste bags, resulting in a cumbersome and inefficient process.

[0004] Therefore, it is necessary to provide a new technical solution to solve the above-mentioned technical problems. Utility Model Content

[0011] Optionally, the membrane sludge recycling device further includes a first temperature sensor disposed on the extrusion assembly, the first temperature sensor being used to collect extrusion temperature information of the extrusion assembly.

[0012] Optionally, the drying tank is provided with an outlet, and the membrane sludge recycling device further includes a rolling assembly, which includes a roller disposed at the outlet and a second driver connected to the roller, the second driver driving the roller to rotate to squeeze the membrane sludge.

[0016] Beneficial effects:

[0017] This invention provides a membrane sludge recycling device. A feeding assembly conveys the membrane sludge to the first and second extrusion rods of an extrusion assembly. A first driver of the extrusion assembly drives the first and second extrusion rods to rotate and extrude the membrane sludge. A heating element is connected to both the first and second extrusion rods, heating them. The heated first and second extrusion rods then perform initial extrusion drying on the membrane sludge.

[0030] This utility model provides a membrane sludge recovery device. Please refer to [link to relevant documentation]. Figures 1 to 5 As shown, Figure 1 This is a schematic diagram of the structure of a membrane sludge recovery device provided in an embodiment of this utility model. Figure 2 This is a schematic diagram of a portion of the structure of a membrane sludge recovery device provided in an embodiment of this utility model. Figure 3 This is a schematic diagram of the feeding trough and auxiliary trough in a membrane sludge recycling device provided in an embodiment of this utility model. Figure 4 This is a schematic diagram of the structure of the drying tank, drum, and first temperature sensor in a membrane sludge recycling device provided in an embodiment of this utility model. Figure 5 This is a schematic diagram of the conveying mechanism and drying tank in a membrane slag recovery device provided in this embodiment of the present invention. The membrane slag recovery device provided in this embodiment of the present invention includes a feeding assembly 113, an extrusion assembly 1, a heating element 2, and a drying tank 3. The extrusion assembly 1 includes a first driver 12, a first extrusion rod 101, and a second extrusion rod 102. The first driver 12 is connected to the first extrusion rod 101 and the second extrusion rod 102. The first extrusion rod 101 and the second extrusion rod 102 can be arranged side by side. The membrane slag is conveyed to the first extrusion rod 101 and the second extrusion rod 102 through the feeding assembly 113. That is, after the membrane slag entering the feeding assembly 113 comes into contact with the first extrusion rod 101 and the second extrusion rod 102, the membrane slag to be extruded is supplied to the rotating first extrusion rod 101 and the second extrusion rod 102 respectively. The first driver 12 drives the first extrusion rod 101 and the second extrusion rod 102 to rotate and extrude the membrane slag. The heating element 2 is connected to the first extrusion rod 101 and the second extrusion rod 102 and is used to heat the first extrusion rod 101 and the second extrusion rod 102. The heating element 2 heats the first extrusion rod 101 and the second extrusion rod 102 to perform initial extrusion drying on the membrane slag during the extrusion process. The drying tank 3 contains the membrane slag after the initial extrusion drying.

[0031] In this configuration, the first extrusion rod 101 and the second extrusion rod 102 can be arranged side-by-side on the same horizontal plane. In this case, the first driver 12 can include two motors, each connected to the first extrusion rod 101 and the second extrusion rod 102 respectively. The two motors drive the first extrusion rod 101 and the second extrusion rod 102 to rotate, thereby extruding the membrane residue near the first extrusion rod 101 and the second extrusion rod 102. Simultaneously, the heating element 2 is connected to the first extrusion rod 101 and the second extrusion rod 102, transferring the heat generated by the heating element 2 to the first extrusion rod 101 and the second extrusion rod 102, thus drying the membrane residue being extruded by the first extrusion rod 101 and the second extrusion rod 102. In other embodiments, a third extrusion rod, or even a fourth extrusion rod, can be provided, depending on the actual situation. Alternatively, a single motor can drive all the extrusion rods to rotate.

[0032] The heating element 2, connected to the first extrusion rod 101 and the second extrusion rod 102 of the extrusion assembly 1, generates heat to initially extrude and dry the membrane sludge during the extrusion process. This allows the membrane sludge to undergo heat treatment while being extruded, accelerating moisture evaporation. At this time, part of the moisture contained in the membrane sludge evaporates to form water vapor, while at least a certain amount of moisture is discharged from the membrane sludge after extrusion, forming liquid water. This achieves an initial separation of the membrane sludge and the moisture it contains. Subsequently, the membrane sludge with initially separated moisture is promptly transported to the interior of the drying tank 3. This can be achieved by tilting the extrusion assembly towards the drying tank 3, moving the extruded membrane sludge towards the drying tank 3, or by using a rotating screw 11 to move the extruded membrane sludge towards the drying tank 3, or by manual operation to transport the extruded membrane sludge into the drying tank 3. The drying tank 3 has a space to accommodate the membrane sludge. After the membrane sludge enters the drying tank 3, it avoids contact between the membrane sludge and the aforementioned water vapor or liquid water, thus achieving membrane sludge with low moisture content. In addition, the bottom of the drying tank 3 can be inclined to facilitate the smooth movement of the membrane residue inside the drying tank 3 to the outlet 31 of the drying tank 3.

[0033] In this embodiment, the membrane residue is conveyed to the first extrusion rod 101 and the second extrusion rod 102 by the feeding assembly 113. The first driver 12 of the extrusion assembly 1 drives the first extrusion rod 101 and the second extrusion rod 102 to rotate to extrude the membrane residue. The heating element 2 is connected to the first extrusion rod 101 and the second extrusion rod 102 respectively. The heating element 2 heats the first extrusion rod 101 and the second extrusion rod 102. The membrane residue is initially extruded and dried by the heated first extrusion rod 101 and the second extrusion rod 102. The drying tank 3 contains the membrane residue after the initial extrusion and drying. The membrane sludge entering the first extrusion rod 101 and the second extrusion rod 102 undergoes initial mechanical extrusion, reducing its volume and moisture content. Simultaneously, the heating element 2 heats the first and second extrusion rods 101 and 102, transferring the heat to the membrane sludge during this initial extrusion drying process. This allows the membrane sludge to undergo immediate heat treatment during extrusion, improving the removal efficiency of moisture. After this initial drying, the membrane sludge enters the drying tank 3 for secondary heating and drying, further removing as much moisture as possible and reducing its moisture content. This achieves the technical effect of reducing the moisture content of the membrane sludge and improving treatment efficiency.

[0034] In another embodiment, the membrane residue can be conveyed to the feeding trough 13 via a conveyor belt. The membrane residue located in the feeding trough 13 is rotated and fed by the first extrusion rod 101 and the second extrusion rod 102 located on the feeding trough 13. The specific process of the membrane residue in the feeding trough 13 from the feeding trough 13 to the screw 11 is as follows: after the membrane residue enters the feeding trough 13, it will accumulate towards the direction of the screw 11. For example, after the membrane residue is conveyed to the feeding trough 13, the membrane residue inside the feeding trough 13 will accumulate to a point greater than its own angle of accumulation and then tilt towards the direction of the screw 11, so that the membrane residue and the screw 11 come into contact with each other. Alternatively, the bottom of the feeding trough 13 can be set to tilt towards the direction of the screw 11. When the membrane residue enters the interior of the feeding trough 13, the membrane residue will tilt towards the direction of the screw 11 under the guidance of the tilted bottom of the feeding trough 13, so that the membrane residue and the screw 11 come into contact with each other. After the membrane residue comes into contact with the screw 11, it is squeezed and rotated under the rotation of the screw 11, that is, the rotating screw 11 drives the membrane residue to move toward the direction closer to the drying tank 3.

[0035] As one implementation method, please refer to Figure 1 and Figure 2The first extrusion rod 101 and the second extrusion rod 102 are screws 11 with mounting grooves 111 for placing heating elements 2. A first driver 12 is connected to the screw 11 and drives the screw 11 to rotate to extrude the membrane residue. The mounting grooves 111 of the screw 11 have space to accommodate the heating elements 2. The heat generated by the heating elements 2 heats the screw 11, increasing its temperature. During the extrusion of the membrane residue by the rotation of the screw 11, the heating elements 2 (which can be made of metal) heat and dry the membrane residue during the extrusion process, allowing it to undergo heat treatment immediately while being mechanically extruded, thus accelerating moisture removal. Furthermore, during the rotation of the screw 11, the threads on the screw 11 drive the initially heated and dried membrane residue towards the drying tank 3, thus conveying the initially heated and dried membrane residue into the drying tank 3.

[0036] In some implementations, please refer to [link / reference]. Figure 1 and Figure 2 The heating element 2 includes a heating resistance wire 21. To provide a detailed description of the installation method of the heating element 2 located on the screw 11, two embodiments are provided below. The first embodiment is that the heating element 2 is installed inside the screw 11. Specifically, the mounting groove 111 can be located inside the screw 11, and the mounting groove 111 is distributed around the screw 11 along the length of the screw 11. The heating element 2 is installed inside the screw 11 by embedding the heating resistance wire 21 into the mounting groove 111 located inside the screw 11. The shape of the heating resistance wire 21 can be straight, curved, etc. In a preferred embodiment, the heating resistance wire 21 is spiral. The spiral heating resistance wire 21 can distribute heat more evenly, so that the membrane slag is fully heated and dried during the extrusion process, which not only improves the drying efficiency, but also helps to maintain the uniformity and stability of the membrane slag. In the second embodiment, the heating element 2 is installed on the outside of the screw 11. Specifically, the mounting groove 111 is provided on the outer surface of the screw 11. The mounting groove 111 on the outer surface of the screw 11 has a space for placing the heating resistance wire 21. The heating resistance wire 21 is embedded in the interior of the mounting groove 111, so that the heating element 2 is installed on the outside of the screw 11. The screw 11 and the film residue are heated by the heating resistance wire 21 in the mounting groove 111 on the outside of the screw 11. After the heating resistance wire 21 is placed on the outer surface of the screw 11, it is convenient to maintain and replace the heating resistance wire 21.

[0037] In some implementations, please refer to Figures 1 to 3The extrusion assembly 1 includes a feeding trough 13, which is located below the screw 11 and directly opposite the screw 11. The feeding trough 13 is used to supply the membrane sludge to be processed to the screw 11. The membrane sludge recycling device provided in this embodiment also includes a secondary trough 14, inside which the feeding trough 13 is disposed. The secondary trough 14 is located below the screw 11 and is connected to the feeding trough 13 via a transmission mechanism 15. For example, there can be two transmission mechanisms 15. One transmission mechanism 15 has its two ends connected to the secondary trough 14 and the main equipment 8, respectively, while the other transmission mechanism 15 has its two ends connected to the main equipment 8 and the feeding trough 13, respectively. This creates a channel between the secondary trough 14 and the feeding trough 13, which is used to supply the membrane sludge from the secondary trough 14 to the main equipment 8. After being used by the main equipment 8, the membrane sludge will be... The membrane sludge entering the feed trough 13 through the channel, i.e., the membrane sludge in the secondary trough 14, can be transported into the feed trough 13 by the conveying mechanism 15. If the bottom of the secondary trough 14 is inclined towards the conveying mechanism 15, the membrane sludge entering the secondary trough 14 will enter the conveying mechanism 15 from the outlet of the secondary trough 14 directly opposite the conveying mechanism 15 along the inclined direction. The membrane sludge on the conveying mechanism 15 will enter the feed trough 13 from the top opening of the feed trough 13 along the conveying direction of the conveying mechanism 15. The membrane sludge transported to the feed trough 13 can be squeezed again by the screw 11, i.e., the membrane sludge in the secondary trough 14 can be transported into the feed trough 13 by the conveying mechanism 15. The conveying mechanism 15 in the membrane sludge recycling device provided in this utility model embodiment has the same structure and principle as the conveying mechanism 6 described below, and the conveying mechanism 15 will not be described in detail here. The membrane residue generated by the main equipment 8 enters the feeding trough 13 through the conveying mechanism 15, and then enters the extrusion area of ​​the screw 11. After being extruded by the screw 11, the membrane residue is guided by the screw 11 into the drying tank 3 for secondary drying.

[0038] In some implementations, please refer to Figure 1 and Figure 4 The drying tank 3 is used for secondary heating and drying of the membrane residue after the initial heating and drying. By subjecting the membrane residue to more thorough secondary heating and drying, the moisture content of the membrane residue can be further reduced. For example, a circulating hot air system can be configured inside the drying tank 3, or an infrared heater can be installed on the inner wall of the drying tank 3, which can generate sufficient heat in a short time to maximize the removal of moisture contained in the membrane residue.

[0039] In some implementations, please refer to [link / reference]. Figures 1 to 3The system has at least two screws 11, with a gap 112 between adjacent screws 11. The projection of the gap 112 onto the feeding trough 13 along the direction near the feeding trough 13 is at least partially located in the feeding trough 13, and the projection of the gap 112 onto the drying trough 3 along the direction near the drying trough 3 is also at least partially located in the drying trough 3. This allows the membrane residue being extruded by the screws 11 to enter the drying trough 3. Multiple screws 11 can further improve the extrusion efficiency. During the rotation of multiple screws 11, the membrane residue passes through the gap 112 between adjacent screws 11, and the adjacent screws 11 extrude pressure on the membrane residue passing through the gap 112. For example, during the rotation of two adjacent screws 11, since the projection of the gap 112 onto the feeding trough 13 along the direction near the feeding trough 13 is at least partially located in the feeding trough 13, the membrane residue located in the feeding trough 13 will enter the gap 112 between the two screws 11 and be extruded. Meanwhile, when the screw 11 rotates, the threads on the screw 11 will drive the membrane residue to move towards the drying tank 3. At this time, the membrane residue that has been squeezed will move into the interior of the drying tank 3, which helps to reduce the blockage and accumulation of membrane residue.

[0040] In some implementations, please refer to Figure 2 The membrane sludge recycling device provided in this embodiment of the invention also includes a first temperature sensor 5, which is disposed in the extrusion assembly 1. The first temperature sensor 5 is used to collect the extrusion temperature information of the extrusion assembly 1, which refers to the surface temperature of the screw 11. The first temperature sensor 5 can monitor the temperature change of the extrusion assembly 1 in real time, so that the membrane sludge is always within a suitable temperature range during the extrusion process, which helps to prevent the membrane sludge from being damaged due to overheating.

[0041] In some implementations, please refer to Figure 1 and Figure 4The drying tank 3 has an outlet 31. The membrane sludge recycling device provided in this embodiment also includes a rolling assembly 4, which includes a roller 41 and a second driver 42. The roller 41 is located at the outlet 31 of the drying tank 3, and the second driver 42 is connected to the roller 41. The second driver 42 drives the roller 41 to rotate to squeeze the membrane sludge. The second driver 42 includes a motor or a cylinder. After the membrane sludge is initially dried by the squeezing assembly 1, it enters the drying tank 3 for secondary drying, where the moisture in the membrane sludge can be further removed. Then, the membrane sludge is discharged from the outlet 31 of the drying tank 3, and the second driver 42 drives the roller 41 located at the outlet 31 to rotate, allowing the membrane sludge to be squeezed again by the roller 41 of the rolling assembly 4. If the bottom of the drying tank 3 is designed to slope towards the outlet 31, the membrane sludge entering the drying tank 3 will slide along the sloped bottom to the outlet 31. The membrane sludge at the outlet 31 will then contact the roller 41 located at the outlet 31, and the rotation of the roller 41 will compress the membrane sludge. This rotational compression of the roller 41 not only helps remove residual moisture from the membrane sludge but also makes the membrane sludge more compact and shapeable, further reducing its moisture content and improving processing efficiency.

[0042] In some implementations, please refer to Figure 1 and Figure 5 The membrane sludge recycling device provided in this embodiment of the invention further includes a conveying mechanism 6 and a collection tank 7. The conveying mechanism 6 is disposed between the collection tank 7 and the outlet 31 of the drying tank 3 to form a conveying path between the collection tank 7 and the outlet 31 of the drying tank 3. The membrane sludge is conveyed from the outlet 31 of the drying tank 3 to the collection tank 7 through the conveying path. After the membrane sludge is output from the outlet 31 of the drying tank 3, it is conveyed into the collection tank 7 by the conveying mechanism 6, which improves the continuity of membrane sludge treatment and reduces the difficulty and cost of manual operation.

[0043] In some implementations, please refer to [link / reference]. Figure 1 and Figure 5 The conveying mechanism 6 includes a support frame 61, a synchronous pulley 62, a third drive 63, and an annular belt 64. The synchronous pulley 62 is mounted on the support frame 61, and the third drive 63 drives the synchronous pulley 62 to rotate. The annular belt 64 surrounds the synchronous pulley 62. The outlet 31 of the drying tank 3 and the collection tank 7 are located at opposite ends of the annular belt 64. The third drive 63 drives the synchronous pulley 62 to move the annular belt 64, conveying the membrane residue inside the drying tank 3 through the outlet 31 to the collection tank 7. The membrane residue output from the outlet 31 of the drying tank 3 is conveyed into the collection tank 7 by the annular belt 64. The annular belt 64 and the synchronous pulley 62 make the conveying process more stable and reliable, and the membrane residue is less likely to fall or break during the conveying process. This not only improves the conveying efficiency of the membrane residue but also helps to ensure the integrity of the membrane residue.

[0044] In some implementations, please refer to Figure 1 and Figure 4 The membrane sludge recycling device provided in this embodiment of the invention also includes a second temperature sensor 51, which is installed in the drying tank 3. The second temperature sensor 51 is used to collect drying temperature information inside the drying tank 3, which refers to the temperature inside the drying tank 3. The opening of the drying tank 3 faces the screw 11. After being squeezed by the screw 11, the membrane sludge enters the drying tank 3, where it undergoes secondary drying to further remove moisture. To ensure the stability and controllability of the drying process, the second temperature sensor 51 can be installed inside the drying tank 3. The second temperature sensor 51 can monitor the temperature information inside the drying tank 3 in real time and transmit the data to the control system. The control system adjusts parameters such as the heating power or drying time of the heating element 2 according to the temperature information to ensure that the membrane sludge is dried at a suitable temperature. This not only improves the stability and controllability of the drying process but also helps to reduce energy consumption and production costs.

[0045] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
