Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cell recycling and processing, and in particular to a pre-crushing process equipment and method for crushing component EVA cell layers. Background Art

[0002] Photovoltaic modules are devices that can convert solar energy into electrical energy, including packaging materials (frames, junction boxes, cables) and laminates stacked from bottom to top (backplane or glass substrate, organic adhesive layer, battery layer, organic adhesive layer, glass substrate. Except for the organic adhesive layer, most of the components such as silicon, aluminum, silver, and glass in the packaging materials and laminates can be recycled and reused. As the operating time increases, the power generation efficiency of photovoltaic modules gradually decreases. In order to achieve better power generation performance, old photovoltaic modules need to be replaced. Recycling discarded photovoltaic modules can not only protect the environment but also effectively save resources.

[0003] At present, physical separation is mostly used for recycling photovoltaic modules. First, the aluminum frame, junction box, back panel and glass are removed to obtain EVA battery laminates. The EVA battery laminates are placed in a rotary kiln for thermal decomposition to remove the EVA glue, thereby obtaining recycled parts such as silicon wafers and solder strips. For EVA battery laminates, they need to be cut and crushed before being placed in the rotary kiln to avoid agglomeration of the laminates during the thermal decomposition process of the rotary kiln, which affects the thermal tapping efficiency. Currently, crushing equipment is mostly used to tear the EVA battery laminates into small pieces, and then put them into the rotary kiln for thermal decomposition. However, the current crushing equipment cannot split and cut the solder strips. In the rotary kiln, the longer solder strips are entangled into balls, affecting subsequent operations.

The following is an explanation of the embodiments of the present invention based on its overall structure.

[0033] Example 1

[0034] Reference Figure 1 , a crushing component EVA battery layer pre-crushing process equipment includes a synchronous feeding mechanism 1, a longitudinal cutting mechanism 2 and a transverse cutting mechanism 3;

[0035] A synchronous feeding mechanism 1, which is used to transport the EVA battery layer to the feeding port of the longitudinal cutting mechanism 2, and the synchronous feeding mechanism 1 is installed above the longitudinal cutting mechanism 2;

[0036] A longitudinal cutting mechanism 2, wherein the longitudinal cutting mechanism 2 is used to longitudinally cut the EVA battery layer, and the longitudinal cutting mechanism 2 is installed above the cross-cutting mechanism 3;

[0037] The cross-cutting mechanism 3 and the longitudinal cutting mechanism 2 are used for cutting the EVA battery layer transversely.

[0038] When the device is working, the following steps are included:

[0039] Step S1: The photovoltaic panel EVA battery layer is conveyed to the top of the longitudinal cutting mechanism 2 by the synchronous feeding mechanism 1. The EVA battery layer falls into the feeding port of the longitudinal mechanism 2.

[0040] Step S2: longitudinally cutting the EVA battery layer by the longitudinal cutting mechanism 2. The longitudinally cut EVA battery layer falls into the feed port of the transverse cutting mechanism 3.

[0041] Step S3: The EVA battery layer is cut transversely by the transverse cutting mechanism 3 .

[0042] Example 2

[0043] Reference Figure 2 The difference between this embodiment and embodiment 1 is that the synchronous feeding mechanism 1 includes a conveyor belt 4, a conveying motor 5, a synchronous wheel set 6 and a feeding synchronous gear set 7; the upper end of the conveyor belt 4 is located above the longitudinal cutting mechanism 2; the synchronous wheel set 6 is installed on the side of the upper end of the conveyor belt 4; the conveying motor 5 is installed at one end of the synchronous wheel set 6, and the longitudinal feeding synchronous gear set 7 is installed at the other end; the feeding synchronous gear set 7 is respectively connected to the conveyor belt 4 and the synchronous wheel set 6.

[0044] The conveyor belt 4 is used to convey the EVA battery layer; when working, the EVA battery layer is placed at the lower end of the conveyor belt 4. After the EVA battery layer moves to the upper end of the conveyor belt 4, it falls into the longitudinal cutting mechanism 2 below from the gap between the conveyor belt 4 and the synchronous wheel group 6, and the synchronous wheel group 6 plays a positioning role.

[0045] The positioning function of the synchronous wheel set 6 ensures that the EVA battery layer can accurately fall into the longitudinal cutting mechanism 2, thereby improving the stability and accuracy of the loading. At the same time, this design makes the loading process smoother and reduces the occurrence of jams and misalignments.

[0046] The working principle of this embodiment is the same as that of Embodiment 1.

[0047] Example 3

[0048] Reference Figure 6This embodiment differs from Embodiment 2 in that it further includes a mounting plate 23 and a mounting base 24; mounting plates 23 are respectively provided on both sides of the conveyor belt 4; the mounting base 24 is mounted on the mounting plate 23; the conveying motor 5 is mounted on the outer side of the mounting plate 23, and the synchronous wheel set 6 is mounted on the inner side.

[0049] The mounting base 24 is mounted on the mounting plate 23 by bolts. By adjusting the position of the mounting plate 23, the distance between the synchronous wheel set 6 and the upper edge of the conveyor belt 4 can be adjusted to adapt to the conveying of EVA battery layers of different thicknesses.

[0050] The adaptability of the equipment is increased, and it can process EVA battery layers of different thicknesses, which improves the versatility and flexibility of the equipment. It can be adjusted according to actual production needs to meet the processing requirements of EVA battery layers of different specifications.

[0051] The working principle of this embodiment is the same as that of Embodiment 1.

[0052] Example 4

[0053] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 3 is that the synchronous wheel set 6 includes a positioning wheel 25 and a discharge roller rod 26; the feeding synchronous gear set 7 includes a first feeding synchronous gear 27 and a second feeding synchronous gear 28; the positioning wheel 25 is installed on the rod body of the discharge roller rod 26, one end of which is connected to the conveying motor 5, and the other end is installed with the first feeding synchronous gear 27; the upper end of the conveyor belt 4 is provided with a conveyor belt roller rod 29, and one end of the conveyor belt roller rod 29 is installed with the second feeding synchronous gear 28; the first feeding synchronous gear 27 and the second feeding synchronous gear 28 are connected.

[0054] The first synchronous feeding gear 27 and the second synchronous feeding gear 28 play a transmission role. When the conveying motor 5 drives the unloading roller rod 26 to rotate, the first synchronous feeding gear 27 drives the second synchronous feeding gear 28 to rotate, and the second synchronous feeding gear 28 drives the conveyor belt roller rod 29 to rotate, thereby driving the conveyor belt 4 to work and convey the EVA battery layer. Stable conveying is achieved through gear transmission, ensuring the continuous supply of the EVA battery layer. Gear transmission has the characteristics of high precision and strong reliability, which can ensure the stability and accuracy of the conveying process and improve production efficiency.

[0055] The working principle of this embodiment is the same as that of Embodiment 1.

[0056] Example 5

[0057] Reference Figure 3The difference between this embodiment and embodiment 4 is that the longitudinal cutting mechanism 2 includes a longitudinal cutting motor 8, a longitudinal cutting component 9, a mounting shell 10, a longitudinal cutting transmission shaft 11 and a longitudinal cutting synchronous gear set 12; the longitudinal cutting transmission shaft 11 is horizontally installed in the middle of the mounting shell 10, the longitudinal cutting motor 8 is installed at one end, and the longitudinal cutting synchronous gear set 12 is installed at the other end; the longitudinal cutting component 9 is installed on the longitudinal cutting transmission shaft 11; one end of the longitudinal cutting transmission shaft 11 is connected to the longitudinal cutting motor 8, and the other end is connected to the longitudinal cutting synchronous gear set 12.

[0058] Two longitudinal cutting drive shafts 11 are horizontally installed in the middle of the installation shell 10, one of which is a driving shaft connected to the longitudinal cutting motor 8; the other longitudinal cutting drive shaft 11 is a driven shaft, which is driven to rotate by the driving shaft through the longitudinal cutting synchronous gear set 12; the two longitudinal cutting drive shafts 11 are respectively provided with longitudinal cutting components 9 to cut the EVA battery layer, thereby improving the efficiency and accuracy of longitudinal cutting and ensuring the longitudinal cutting effect of the EVA battery layer. The design of the two longitudinal cutting drive shafts 11 makes the cutting more uniform and stable, and can meet the cutting requirements of EVA battery layers of different sizes and thicknesses. At the same time, the transmission of the longitudinal cutting synchronous gear set 12 ensures the synchronous operation of the two longitudinal cutting drive shafts 12, thereby improving the reliability of the equipment.

[0059] The working principle of this embodiment is the same as that of Embodiment 1.

[0060] Example 6

[0061] Reference Figure 8 The difference between this embodiment and embodiment 5 is that the longitudinal cutting assembly 9 includes a disc cutter 30 and a fixing ring 31; the fixing ring 31 is installed on the longitudinal cutting transmission shaft 11, and the disc cutter 30 is installed on the side of the fixing ring 31.

[0062] The fixing ring 31 is detachably mounted on the longitudinal cutting transmission shaft 11 by bolts. Multiple sets of fixing rings 31 and disc cutters 30 are mounted on the longitudinal cutting transmission shaft 11. By adjusting the distance between the fixing rings 31, the cutting distance of the disc cutter 30 to the EVA battery layer can be adjusted, so that the cutting size can be adjusted according to different requirements, thereby improving the flexibility of the equipment. The position and spacing of the disc cutter 30 can be flexibly adjusted according to actual production requirements to meet the cutting requirements of EVA battery layers of different specifications. At the same time, the detachable fixing ring design makes it more convenient and quick to replace and maintain the disc cutter 30.

[0063] The working principle of this embodiment is the same as that of Embodiment 1.

[0064] Example 7

[0065] Reference Figure 4 and Figure 5The difference between this embodiment and embodiment 6 is that the cross-cutting mechanism 3 includes a camshaft 13, a cam 14, a cam connecting rod 15, a mounting frame 16, a cross-cutting motor 17, an upper gate knife 18 and a lower gate knife 19; the camshaft 13 is installed in the middle part of the mounting frame 16, the cross-cutting motor 17 is installed at the lower end, and the upper gate knife 18 and the lower gate knife 19 are installed at the upper end; one end of the camshaft 13 is connected to the cross-cutting motor 17, and the other end is installed with the cam 14; the upper gate knife 18 is installed above the lower gate knife 19; one end of the cam connecting rod 15 is connected to the cam 14, and the other end is connected to the upper gate knife 18.

[0066] The cross-cutting motor 17 is connected to the camshaft 13 through a belt transmission mechanism. The cross-cutting motor 17 drives the camshaft 13 and the cam 14 to rotate, and the cam 14 drives the cam connecting rod 15 to move, thereby driving the lower gate knife 19 to move horizontally to cut the EVA battery layer, thereby achieving efficient horizontal cutting and improving the integrity of the crushing. The design of the cam mechanism makes the movement of the lower gate knife 19 more stable and precise, which can ensure the effect of horizontal cutting. At the same time, the use of the belt transmission mechanism reduces the noise and vibration of the equipment and improves the stability and reliability of the equipment.

[0067] The working principle of this embodiment is the same as that of Embodiment 1.

[0068] Example 8

[0069] Reference Figure 5 The difference between this embodiment and embodiment 7 is that it further includes a slide plate 21; the lower gate knife 19 is installed at the front end of the slide plate 21; one end of the slide plate 21 is connected to the cam connecting rod 15.

[0070] A transverse slide rail is arranged in the middle of the mounting frame 16, and the two ends of the slide plate 21 are respectively connected to the transverse slide rail; the slide plate 21 and the cam connecting rod 15 form a crank slider structure. When the camshaft 13 drives the cam 14 to rotate, the rotation of the cam 14 drives the cam connecting rod 15 to move, so that the slide plate 21 moves horizontally, driving the lower gate knife 19 installed at the front end of the slide plate 21 to move, cutting the EVA battery layer, improving the stability and accuracy of the movement of the lower gate knife 19, and ensuring the transverse cutting effect. The design of the crank slider structure makes the movement of the slide plate 21 more stable and precise, can reduce the shaking and deviation of the lower gate knife 19 during the cutting process, and improves the quality and accuracy of the cutting. At the same time, the setting of the transverse slide rail makes the movement of the slide plate smoother and reduces friction and resistance.

[0071] The working principle of this embodiment is the same as that of Embodiment 1.

[0072] Example 9

[0073] Reference Figure 5The difference between this embodiment and embodiment 8 is that it also includes a baffle 20; the baffle 20 is installed above the upper gate knife 18.

[0074] It also includes a material collection box 22 ; the material collection box 22 is installed below the lower gate knife 19 .

[0075] The baffle 20 prevents the cut material from splashing, and the collection box 22 is convenient for collecting the cut material, thereby improving the safety and cleanliness of the working environment.

[0076] The working principle of this embodiment is the same as that of Embodiment 1.

[0077] In summary, the present invention has the following beneficial effects:

[0078] The present invention can efficiently pre-crush the EVA battery layer by setting the synergistic effect of the synchronous feeding mechanism 1, the longitudinal cutting mechanism 2 and the transverse cutting mechanism 3. The battery layer is cut horizontally and vertically, so that the size of the crushed material is more uniform, which is convenient for the smooth progress of the subsequent thermal decomposition process, thereby greatly improving the recovery efficiency of each component of the photovoltaic panel.

[0079] The cutting size of the equipment can be adjusted according to demand, which makes it more flexible when processing EVA battery layers of different specifications. The cutting size can be accurately controlled according to actual conditions to ensure that the crushed materials meet the requirements of subsequent processes, improving the controllability and stability of the recycling process.

[0080] By cutting the EVA battery layer horizontally and vertically, the components of the photovoltaic panel can be effectively separated, providing convenient conditions for separate recycling. Different components can be recycled separately, which improves the purity and value of recycled resources and reduces pollution to the environment.

[0081] The synchronous feeding mechanism 1 is installed above the longitudinal cutting mechanism 2, and the longitudinal cutting mechanism 2 is installed above the transverse cutting mechanism 3, so that the equipment structure is compact and occupies a small space. At the same time, this layout also facilitates operation and maintenance, improves the versatility and applicability of the equipment, and can be widely used in photovoltaic panel recycling production lines of different scales.

[0082] The efficient crushing and precise cutting functions of the present invention reduce the need for manual intervention and reduce labor costs. At the same time, by recycling each component of the photovoltaic panel separately, the utilization rate of recycled resources can be improved, the cost of raw material procurement can be reduced, and the overall production cost of photovoltaic panel recycling can be reduced.

[0083] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
