Description

Technical Field

[0001] The invention relates to the technical field of waste photovoltaic component processing, and in particular to a waste photovoltaic component crushing device. Background Art

[0002] Photovoltaic modules are devices that are made up of a certain number of photovoltaic cells connected in series and parallel through wires and packaged. The main function of photovoltaic modules is to convert solar energy into electrical energy. They are usually used in solar power generation systems. In the process of recycling waste photovoltaic modules, first of all, the separated photovoltaic cells need to be crushed and decomposed into smaller particles for subsequent processing. Then, chemical methods are used to remove impurities and pollutants on the surface of the cells to expose pure silicon materials.

[0003] In the above recycling process, the waste photovoltaic cells are firstly crushed by a crushing device, wherein the crushing device is generally a single-shaft shredder, which has a simple structure and is mainly composed of a blade spindle, a fixed blade, a box, a bracket, a power system, etc. The overall structure is simple. The waste photovoltaic cells to be crushed are placed in the box, and the blade spindle is rotated. After the comprehensive effects of tearing, squeezing, and shearing of the shredding blade, the shredding operation of the waste photovoltaic cells can be completed;

[0004] However, in the actual working process, directly pouring the discarded photovoltaic modules into the single-axis shredder may cause excessive materials in the subsequent shredding process, resulting in blockage of the feed funnel of the single-axis shredder, which needs to be cleared manually. In addition, excessive discarded photovoltaic modules are stacked together, which will cause greater working pressure on the blade during the subsequent shredding process, thereby reducing the service life of the blade. Secondly, during the long shredding process, the blade is likely to be damaged, and the staff cannot be informed of this situation in time, which affects the shredding effect of the waste photovoltaic modules. Therefore, a discarded photovoltaic module crushing device is provided. Summary of the invention

[0009] Preferably, a control component for controlling the rotational circumference of the connecting cylinder is installed in the connecting cylinder, and the control component includes limit grooves on both sides of the control groove, and limit rods are slidably connected in the two limit grooves. A moving rod is slidably connected in the connecting cylinder, and a first connecting ring is rotatably connected to the outer side of the moving rod. The limit rod and the first connecting ring are fixedly connected, and the square rod is located in the circular plate. One end is fixedly connected to a connecting line, and the connecting line is fixedly connected to the moving rod.

[0010] Preferably, the outer side of the table is slidably connected to a rotating cover, the upper side of the rotating cover is rotatably connected to a third connecting ring, a third spring is fixedly connected between the third connecting ring and the control plate, the upper side of the rotating cover is rotatably connected to a second connecting ring, the outer side of the rotating shaft is also fixedly connected to a cam, the outer side of the fixed plate is slidably connected to an arc plate, the outer side of the arc plate is fixedly connected to a fourth connecting rod, the outer side of the fourth connecting rod is fixedly connected to a second connecting rod, the upper side of the second connecting rod is fixedly connected to a fifth connecting rod, and the upper side of the fifth connecting rod is fixedly connected to the third connecting rod.

[0018] 4. In the actual working process, if the fixed blade or rotating blade on the upper side of a filter plate is damaged, the shredding effect of the discarded photovoltaic components on the upper side of the filter plate will be average. Most of the discarded photovoltaic components will fall on the upper side of the filter plate, which will cause the electrical signal emitted by the pressure sensor to change rapidly. The hydraulic rod is activated, and the working area on the upper side of the filter plate can also be closed. In this process, generally only one hydraulic rod is activated. The staff can use detection equipment such as voltmeters and ammeters to check the size of the electrical signal emitted by the pressure sensor, and then detect the degree of damage to the rotating blade and the fixed blade.

DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 10 , a waste photovoltaic module crushing device, comprising a housing 3, such as Figure 2 , Figure 3 A feed hopper 2 is fixedly connected to the outer upper side of the shell 3, a motor 1 is fixedly installed on the outer side of the shell 3, a rotating shaft 4 is rotatably connected inside the shell 3, one end of the rotating shaft 4 passes through the shell 3, and the rotating shaft 4 is connected to the output shaft of the motor 1 through a pulley assembly, a plurality of rotating blades 9 are fixedly connected to the outer side of the rotating shaft 4, a fixed plate 5 is fixedly connected inside the shell 3, a plurality of fixed blades 10 are fixedly connected to the outer side of the fixed plate 5, and the plurality of fixed blades 10 and the rotating blades 9 are staggered, a stopper 6 is fixedly connected inside the shell 3, a plurality of filter plates 7 are slidably connected inside the shell 3, a pressure sensor 8 is fixedly connected between the plurality of filter plates 7 and the shell 3, and the corners of the stopper 6 are smoothly chamfered;

[0031] First, the pressure sensor 8 is a device or apparatus that can sense pressure signals and convert the pressure signals into usable output electrical signals according to a certain rule. Secondly, under the obstruction of the block 6, the discarded photovoltaic components entering the housing 3 can fall exactly in the middle of the rotating blade 9 and the fixed blade 10. When the discarded photovoltaic components need to be crushed, the motor 1 is started, and the output shaft of the motor 1 drives the rotating shaft 4 to rotate through the pulley assembly, and the rotating shaft 4 drives the rotating blade 9 to rotate, and the discarded photovoltaic components are poured into the feeding funnel 2. The discarded photovoltaic components fall on the upper side of the rotating blade 9 and the fixed blade 10 through the feeding funnel 2. At this time, the rotating blade 9 and the fixed blade 10 are crushed. Under the action of the fixed blade 10, the discarded photovoltaic components are crushed, and the crushed photovoltaic components fall on the filter plate 7. The photovoltaic components smaller than the diameter of the filter hole on the outer side of the filter plate 7 pass through the filter plate 7 and are discharged from the lower side of the shell 3. The photovoltaic components larger than the diameter of the filter hole on the outer side of the filter plate 7 stay on the upper side of the filter plate 7, thereby increasing the overall gravity of the filter plate 7, causing the electrical signal emitted by the pressure sensor 8 to change. When the electrical signal emitted by the pressure sensor 8 is large, it means that there are more photovoltaic components on the upper side of the filter plate 7. The photovoltaic components on the upper side of the filter plate 7 are taken out and crushed for the second time until the diameter of the filter hole on the outer side of the filter plate 7 is met. The above are all prior arts and no unnecessary elaboration is made.

[0032] like Figure 4 , Figure 5 A drainage assembly is installed in the housing 3, and the drainage assembly includes a first gear 11 fixedly installed on the outside of the rotating shaft 4. A rotating rod 12 is rotatably connected in the housing 3, and a second gear 14 is fixedly connected to the outside of the rotating rod 12. The first gear 11 and the second gear 14 are meshed with each other, and the rotating rod 12 is fixedly connected to a worm 13. A control plate 18 is fixedly connected to the side wall of the feed funnel 2, and a plurality of control grooves 19 are evenly opened on the lower side of the control plate 18. A slide plate 20 is slidably connected in each control groove 19, and a first spring 21 is fixedly connected between the slide plate 20 and the side wall of the control groove 19, and a hydraulic rod is also fixedly connected between the slide plate 20 and the side wall of the control groove 19. 22, the outer side of the slide plate 20 is rotatably connected with a connecting cylinder 23, the outer side of the connecting cylinder 23 is fixedly connected with a round table 24, the outer side of the connecting cylinder 23 is fixedly connected with a circular plate 25, the outer side of the circular plate 25 is circumferentially provided with a plurality of connecting grooves, each of which is slidably connected with a square rod 26, a second spring 30 is fixedly connected between the square rod 26 and the connecting groove, a plurality of first connecting rods 15 are rotatably installed in the housing 3, the outer sides of the plurality of first connecting rods 15 are fixedly connected with a worm gear 16, the worm gear 16 and the worm 13 are meshed, the outer side of the first connecting rod 15 is fixedly connected with a rotating plate 17, and the outer side of the rotating plate 17 is circumferentially fixedly connected with a plurality of connecting plates 27;

[0033] Firstly, in the process of discarding the waste photovoltaic components, in order to maintain the throwing effect, the material pouring operation is often performed at the corners of the feeding funnel 2. When the waste photovoltaic components are shredded, the rotating shaft 4 drives the rotating rod 12 to rotate through the first gear 11 and the second gear 14, and the rotating rod 12 drives the worm 13 to rotate. The worm 13 drives the first connecting rod 15 to rotate through the worm gear 16. The first connecting rod 15 drives the rotating plate 17 and the connecting plate 27 to rotate. After the waste photovoltaic components enter the feeding funnel 2, the table 24 will be squeezed, thereby causing the table 24 to move relative to the feeding funnel 2 as a whole. The table 24 drives the slide plate 20 to move through the connecting cylinder 23, and the slide plate 20 compresses the first connecting rod 15. A spring 21. During this process, the thicker the discarded photovoltaic components are, the greater the distance that the table 24 moves as a whole relative to the feed funnel 2. The stacking of discarded photovoltaic components will affect the subsequent crushing quality. At this time, the connecting plate 27 and the square rod 26 on the outside of the rotating plate 17 are against each other and drive the square rod 26 and the circular plate 25 to rotate around the connecting tube 23. The square rod 26 and the circular plate 25 drive the table 24 to rotate through the connecting tube 23. Since the table 24 is always against the discarded photovoltaic components, the rotating table 24 will drive the discarded photovoltaic components to move, thereby reducing the thickness of the discarded photovoltaic components stacked together, separating the discarded photovoltaic components as much as possible, and ensuring the subsequent shredding quality.

[0034] like Figure 6 , Figure 7 , Figure 8 A control assembly for controlling the rotational circumference of the connecting cylinder 23 is installed in the connecting cylinder 23, and the control assembly includes limit grooves 33 opened on both sides of the control groove 19, and limit rods 32 are slidably connected in the two limit grooves 33. A moving rod 28 is slidably connected in the connecting cylinder 23, and a first connecting ring 31 is rotatably connected to the outer side of the moving rod 28. The limit rod 32 and the first connecting ring 31 are fixedly connected. A square rod 26 is located in the circular plate 25 and is fixedly connected to a connecting line 29 at one end. The connecting line 29 and the moving rod 28 are fixedly connected, and the limit groove 33 is inclined.

[0035] First, in the initial state, the second spring 30 is in a compressed state. Secondly, when the discarded photovoltaic modules are thicker, the table 24 will move as a whole relative to the feed hopper 2. The table 24 drives the limiting rod 32 to move as a whole through the connecting tube 23. Under the action of the limiting groove 33, when the limiting rod 32 moves with the table 24, the limiting rod 32 will move downward relative to the connecting tube 23 as a whole. The limiting rod 32 drives the moving rod 28 to move downward relative to the connecting tube 23 through the first connecting ring 31. Under the action of the connecting line 29, a certain amount of elastic force of the second spring 30 will be released, so that the square rod 26 moves away from the circular plate 25. Figure 7 , which will cause the rotating plate 17 and the circular plate 25 to be Figure 7The following state becomes Figure 7 In the above state, when the square rod 26 and the circular plate 25 approach the rotating plate 17, the square rod 26 will also move relative to the circular plate 25 in a direction away from the circular plate 25. Since the rotation speed and rotation range of the rotating plate 17 and the connecting plate 27 will not change, but the circular plate 25 moves in a direction close to the rotating plate 17, and the square rod 26 will also move relative to the circular plate 25 in a direction away from the circular plate 25. Figure 7 The following state becomes Figure 7 In the above state, the contact time between the connecting plate 27 and the square rod 26 becomes longer, resulting in a longer overall rotational circumference of the circular plate 25 and the square rod 26, which in turn causes the overall rotational circumference of the circular plate 25 to become larger within the same period of time, thereby making the stacked waste photovoltaic components more thoroughly separated, and ultimately achieving the effect of automatically adjusting the rotational circumference of the table 24 according to the thickness of the waste photovoltaic components, and under the action of the table 24, the table 24 is always offset against the waste photovoltaic components, which can reduce the possibility of the waste photovoltaic components clogging the feed funnel 2.

[0036] like Fig. 9 , Fig.10 , a rotating cover 35 is slidably connected to the outer side of the round table 24, and a third connecting ring 43 is rotatably connected to the upper side of the rotating cover 35. A third spring 34 is fixedly connected between the third connecting ring 43 and the control plate 18, and a second connecting ring 36 is rotatably connected to the outer side of the rotating cover 35. A cam 37 is also fixedly connected to the outer side of the rotating shaft 4. An arc plate 40 is slidably connected to the upper side of the fixed plate 5, and a fourth connecting rod 42 is fixedly connected to the outer side of the arc plate 40. A second connecting rod 38 is fixedly connected to the outer side of the fourth connecting rod 42. A fifth connecting rod 41 is fixedly connected to the upper side of the second connecting rod 38, and a third connecting rod 39 is fixedly connected to the upper side of the fifth connecting rod 41. The second connecting rod 38 is slidably connected to the housing 3, and the second connecting rod 38 is located on the upper side of the cam 37, and the surface of the cam 37 is smoothly set. The side wall of the arc plate 40 is fixedly connected with an insertion rod, and the insertion rod and the fixed blade 10 are staggered.

[0037] First, the pressure sensor 8 and the hydraulic rod 22 are electrically connected through wires and a controller. When the electrical signal emitted by the pressure sensor 8 is too large, the electrical signal will be transmitted to the controller, and the controller will control the hydraulic rod 22 to start. This is a conventional technical means, which causes the table 24 to move as a whole in the direction close to the feed funnel 2 until the second connecting ring 36 on the outside of the rotating cover 35 and the inner wall of the feed funnel 2 are against each other, thereby reducing the number of discarded photovoltaic components on the upper side of the filter plate 7. The discarded photovoltaic components will not fall on the upper side of this part of the filter plate 7, that is, the discarded photovoltaic components will not fall between the fixed blade 10 and the rotating blade 9 directly above the filter plate 7. The discarded photovoltaic components on the upper side of the filter plate 7 can be taken out without closing the device as a whole, and in the actual working process, if the fixed blade on the upper side of a certain filter plate 7 When the sheet 10 or the rotating blade 9 is damaged, the shredding effect of the discarded photovoltaic components on the upper side of the filter plate 7 is average, and most of the discarded photovoltaic components fall on the upper side of the filter plate 7, which will cause the electrical signal emitted by the pressure sensor 8 to increase rapidly, and the hydraulic rod 22 is activated, causing the truncated table 24 to move as a whole in the direction close to the feed funnel 2 until the second connecting ring 36 on the outer side of the rotating cover 35 and the inner wall of the feed funnel 2 are against each other. Similarly, the working area on the upper side of the filter plate 7 can be closed, and the discarded photovoltaic components will not fall on the upper side of the filter plate 7, that is, the discarded photovoltaic components will not fall between the fixed blade 10 and the rotating blade 9 located directly above the filter plate 7. The staff can use detection equipment such as a voltmeter and an ammeter to check the size of the electrical signal emitted by the pressure sensor 8, and then detect the degree of damage of the rotating blade 9 and the fixed blade 10;

[0038] Moreover, during the rotation of the rotating shaft 4, the rotating shaft 4 drives the cam 37 to rotate, and the cam 37 drives the arc plate 40 to move up and down through the second connecting rod 38 and the fourth connecting rod 42, and the arc plate 40 drives the insertion rod to move up and down. The insertion rod moving up and down can simply clean the discarded photovoltaic components stuck between the fixed blades 10, thereby ensuring the normal cleaning effect of the fixed blades 10 and the rotating blades 9. At the same time, the second connecting rod 38 will also drive the third connecting rod 39 to move up and down through the fifth connecting rod 41. When the second connecting ring 36 and the inner wall of the feed funnel 2 are against each other, the second connecting ring 36 is just located at the lower side of the third connecting rod 39. The third connecting rod 39 and the second connecting ring 36 that move up and down are against each other and drive the second connecting ring 36 to move up and down. Under the action of the second connecting ring 36 that moves up and down, the possibility of discarded photovoltaic components blocking the feed funnel 2 is further reduced. At the same time, under the action of the second connecting ring 36 that moves up and down and the rotating cover 35, the discarded photovoltaic components are removed from both sides of the second connecting ring 36 and the rotating cover 35, which will not affect the normal shredding effect.

[0039] In the present invention, when it is necessary to crush the discarded photovoltaic components, the motor 1 is started, and the output shaft of the motor 1 drives the rotating shaft 4 to rotate through the pulley assembly, and the rotating shaft 4 drives the rotating blade 9 to rotate, and the discarded photovoltaic components are poured into the feeding funnel 2, and the discarded photovoltaic components fall on the upper side of the rotating blade 9 and the fixed blade 10 through the feeding funnel 2. At this time, under the action of the rotating blade 9 and the fixed blade 10, the discarded photovoltaic components are crushed, and the crushed photovoltaic components fall on the filter plate 7, and the photovoltaic components smaller than the diameter of the filter hole on the outer side of the filter plate 7 pass through the filter plate 7 and are discharged from the lower side of the shell 3, and the photovoltaic components larger than the diameter of the filter hole on the outer side of the filter plate 7 stay on the upper side of the filter plate 7, thereby increasing the overall gravity of the filter plate 7, causing the electrical signal emitted by the pressure sensor 8 to change. When the electrical signal emitted by the pressure sensor 8 is large, it means that there are more photovoltaic components on the upper side of the filter plate 7. The photovoltaic components on the upper side of the filter plate 7 are taken out and crushed for the second time until the diameter of the filter hole on the outer side of the filter plate 7 is met. The above are all prior arts and no unnecessary elaboration is made.

[0040] In the process of throwing in the discarded photovoltaic components, in order to maintain the throwing effect, the material pouring operation is often performed at the corners of the feeding funnel 2. When the discarded photovoltaic components are shredded, the rotating shaft 4 drives the rotating rod 12 to rotate through the first gear 11 and the second gear 14, and the rotating rod 12 drives the worm 13 to rotate. The worm 13 drives the first connecting rod 15 to rotate through the worm gear 16. The first connecting rod 15 drives the rotating plate 17 and the connecting plate 27 to rotate. After the discarded photovoltaic components enter the feeding funnel 2, the round table 24 will be squeezed, thereby causing the round table 24 to move as a whole relative to the feeding funnel 2. The round table 24 drives the slide plate 20 to move through the connecting cylinder 23, and the slide plate 20 compresses the first elastic Spring 21, in this process, the thicker the discarded photovoltaic components, the greater the distance that the truncated table 24 moves relative to the feed funnel 2. The stacking of discarded photovoltaic components will affect the subsequent crushing quality. At this time, the connecting plate 27 and the square rod 26 on the outside of the rotating plate 17 are against each other and drive the square rod 26 and the circular plate 25 to rotate around the connecting cylinder 23. The square rod 26 and the circular plate 25 drive the truncated table 24 to rotate through the connecting cylinder 23. Since the truncated table 24 is always against the discarded photovoltaic components, the rotating truncated table 24 will drive the discarded photovoltaic components to move, thereby reducing the thickness of the discarded photovoltaic components stacked together, separating the discarded photovoltaic components as much as possible, and ensuring the subsequent shredding quality;

[0041] When the discarded photovoltaic modules are thicker, the truncated cone 24 will move as a whole relative to the feed hopper 2. The truncated cone 24 drives the limiting rod 32 to move as a whole through the connecting tube 23. Under the action of the limiting groove 33, when the limiting rod 32 moves with the truncated cone 24, the limiting rod 32 will move downward relative to the connecting tube 23 as a whole. The limiting rod 32 drives the moving rod 28 to move downward relative to the connecting tube 23 through the first connecting ring 31. Under the action of the connecting line 29, a certain amount of elastic force of the second spring 30 will be released, so that the square rod 26 moves away from the circular plate 25. Figure 7 , which will cause the rotating plate 17 and the circular plate 25 to be Figure 7 The following state becomes Figure 7 In the above state, when the square rod 26 and the circular plate 25 approach the rotating plate 17, the square rod 26 will also move relative to the circular plate 25 in a direction away from the circular plate 25. Since the rotation speed and rotation range of the rotating plate 17 and the connecting plate 27 will not change, but the circular plate 25 moves in a direction close to the rotating plate 17, and the square rod 26 will also move relative to the circular plate 25 in a direction away from the circular plate 25. Figure 7 The following state becomes Figure 7 In the above state, the contact time between the connecting plate 27 and the square rod 26 becomes longer, resulting in a longer overall rotation circumference of the circular plate 25 and the square rod 26, which in turn results in a larger overall rotation circumference of the circular plate 25 within the same period of time, thereby making the stacked waste photovoltaic components more thoroughly separated, and ultimately achieving the effect of automatically adjusting the rotation circumference of the round table 24 according to the thickness of the waste photovoltaic components, and under the action of the round table 24, the round table 24 is always offset against the waste photovoltaic components, which can reduce the possibility of the waste photovoltaic components blocking the feed funnel 2;

[0042] When the electrical signal emitted by the pressure sensor 8 is too large, the electrical signal will be transmitted to the controller, and the controller will control the hydraulic rod 22 to start. This method is a conventional technical method, which will cause the truncated table 24 to move as a whole in the direction close to the feed funnel 2 until the second connecting ring 36 on the outside of the rotating cover 35 and the inner wall of the feed funnel 2 are against each other, thereby reducing the number of discarded photovoltaic components on the upper side of the filter plate 7, and ultimately achieving the goal that the discarded photovoltaic components will not fall on the upper side of the filter plate 7, that is, the discarded photovoltaic components will not fall between the fixed blade 10 and the rotating blade 9 located directly above the filter plate 7. The discarded photovoltaic components on the upper side of the filter plate 7 can be taken out without shutting down the device as a whole, and in the actual working process, if the fixed blade 10 or the rotating blade 9 on the upper side of a filter plate 7 is damaged, it will The shredding effect of the discarded photovoltaic components on the upper side of the filter plate 7 is average, and most of the discarded photovoltaic components fall on the upper side of the filter plate 7, which will cause the electrical signal emitted by the pressure sensor 8 to increase rapidly, and the hydraulic rod 22 is activated, causing the truncated table 24 to move as a whole in the direction close to the feed funnel 2 until the second connecting ring 36 on the outer side of the rotating cover 35 and the inner wall of the feed funnel 2 are against each other. Similarly, the working area on the upper side of the filter plate 7 can be closed, and the discarded photovoltaic components will not fall on the upper side of the filter plate 7, that is, the discarded photovoltaic components will not fall between the fixed blade 10 and the rotating blade 9 located directly above the filter plate 7. The staff can use detection equipment such as a voltmeter and an ammeter to check the size of the electrical signal emitted by the pressure sensor 8, and then detect the degree of damage to the rotating blade 9 and the fixed blade 10;

[0043] Moreover, during the rotation of the rotating shaft 4, the rotating shaft 4 drives the cam 37 to rotate, and the cam 37 drives the arc plate 40 to move up and down through the second connecting rod 38 and the fourth connecting rod 42, and the arc plate 40 drives the insertion rod to move up and down. The insertion rod moving up and down can simply clean the discarded photovoltaic components stuck between the fixed blades 10, thereby ensuring the normal cleaning effect of the fixed blades 10 and the rotating blades 9. At the same time, the second connecting rod 38 will also drive the third connecting rod 39 to move up and down through the fifth connecting rod 41. When the second connecting ring 36 and the inner wall of the feed funnel 2 are against each other, the second connecting ring 36 is just located at the lower side of the third connecting rod 39. The third connecting rod 39 and the second connecting ring 36 that move up and down are against each other and drive the second connecting ring 36 to move up and down. Under the action of the second connecting ring 36 that moves up and down, the possibility of discarded photovoltaic components blocking the feed funnel 2 is further reduced. At the same time, under the action of the second connecting ring 36 that moves up and down and the rotating cover 35, the discarded photovoltaic components are removed from both sides of the second connecting ring 36 and the rotating cover 35, which will not affect the normal shredding effect.
