Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel frame production technology, specifically a dust collection device for grinding photovoltaic panel frames. Background Technology

[0002] During the manufacturing and installation of photovoltaic panel frames, aluminum profiles or composite material frames need to be polished. This process generates a large amount of metal or composite material dust, which pollutes the working environment and endangers the respiratory health of operators. To prevent dust from spreading everywhere, dust collection devices are used to collect the metal or composite material dust generated during polishing.

[0003] Current dust collection devices lack the ability to compress collected metal or composite material dust into blocks, which easily leads to secondary dust re-entrainment during subsequent cleaning. Therefore, we propose a dust collection device for grinding photovoltaic panel frames to solve the above problems. Utility Model Content

[0010] The extrusion assembly includes two extrusion cylinders that slide inside a collection box. Each extrusion cylinder has a sliding rod fixed to one side wall. The other end of each sliding rod slides through the collection box to the outside and is fixed with a moving block. A drive mechanism for driving the two extrusion cylinders to move synchronously in opposite directions is installed on the top of the base plate.

[0011] Furthermore, the filter assembly includes four fixing blocks fixed inside the collection box, each fixing block having a spring fixed to its bottom, and the bottom of each of the four springs having a mounting frame fixed to its bottom, with a filter screen fixed inside the mounting frame.

[0012] Furthermore, the driving mechanism includes a drive shaft rotatably connected to the top of the base plate via bearings, a gear fixed on the surface of the drive shaft, two racks slidingly limited on the top of the base plate, both racks meshing with the gears, and the two racks respectively fixedly connected to corresponding moving blocks, and a motor fixedly connected to the bottom of the base plate, the output end of the motor being fixedly connected to the bottom end of the drive shaft.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a dust collection device for grinding the frame of a photovoltaic panel according to one embodiment of the present invention includes a base plate 1. Two T-shaped plates 7 are fixed to the bottom of the base plate 1. Two universal self-locking wheels 8 are fixed to the bottom of each T-shaped plate 7. The universal self-locking wheels 8 installed at the bottom of the T-shaped plates 7 make it easier to operate when the dust collection device needs to be moved close to the ground later. A collection box 2 is fixed to the top of the base plate 1. A dust suction component 3, a filter component 4, and a compression component 5 for compressing the collected dust into blocks are installed on the collection box 2.

[0028] The dust collection assembly 3 includes two dust collection pipes 31 that are connected and fixed to the collection box 2. Each of the two dust collection pipes 31 is equipped with an anti-backflow control valve 9. By using the anti-backflow control valve 9, when the dust collection device stops operating, the dust-laden gas inside the collection box 2 can be prevented from flowing back out through the dust collection hood 32. One end of each of the two dust collection pipes 31 is connected and fixed to the dust collection hood 32. Each of the two openings at the top of the collection box 2 is equipped with an exhaust fan 33. A protective cover 34 is installed above the two exhaust fans 33 and installed on the top of the collection box 2. The protective cover 34 can protect the exhaust fans 33.

[0029] The extrusion assembly 5 includes two extrusion cylinders 51 that slide inside the collection box 2. Each extrusion cylinder 51 has a slide rod 52 fixed on one side wall. The other end of each slide rod 52 slides through the collection box 2 and extends to its outside and is fixed with a moving block 53. The top of the base plate 1 is equipped with a drive mechanism 54 for driving the two extrusion cylinders 51 to move synchronously in opposite directions.

[0030] The working principle and usage process of this utility model are as follows: First, the dust collection device is placed in a suitable position in the photovoltaic panel frame grinding area. When the device is started, the exhaust fan 33 begins to work, and then a negative pressure environment is formed inside the collection box 2. At this time, the dust generated during the photovoltaic panel frame grinding process is sucked in through the dust suction hood 32 under the action of air pressure difference, and then enters the interior of the collection box 2 through the dust suction pipe 31. The dust-laden gas entering the collection box 2 is then processed by the filter component 4, and the dust is trapped inside the collection box 2. The clean gas is discharged from the collection box 2 through the exhaust fan 33. As the collection process proceeds, dust will gradually accumulate in the collection box 2. After the drive mechanism 54 is started, it drives the two moving blocks 53 to move synchronously in opposite directions. After the moving blocks 53 move, the sliding rod 52 can push the two extrusion cylinders 51 to approach each other inside the collection box 2. At this time, the accumulated dust can be extruded and formed into blocks, which is convenient for subsequent cleaning and treatment. When it is necessary to clean the dust that has been extruded into blocks, simply open the cleaning port cover on the front to carry out the cleaning operation.

[0031] like Figure 2As shown, in some embodiments, the filter assembly 4 includes four fixing blocks 41 fixed inside the collection box 2. Each fixing block 41 has a spring 42 fixed to its bottom. The bottom of each of the four springs 42 is fixed with a mounting frame 43. A sealing frame adapted to the collection box 2 is fixed on the mounting frame 43 to enhance the tightness of the mounting frame 43 after it fits against the inner wall of the collection box 2. A filter screen 44 is fixed inside the mounting frame 43. In use, when dusty gas enters the collection box 2, the filter screen 44 can block and collect the dust in the gas inside the collection box 2. The springs 42 cooperate when the filter screen 44 is repeatedly struck by the striking assembly 6, thereby enhancing the cleaning effect of the filter screen 44.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the drive mechanism 54 includes a drive shaft 541 rotatably connected to the top of the base plate 1 via bearings. A gear 542 is fixed to the surface of the drive shaft 541. Two racks 543 are slidably limited at the top of the base plate 1. Two T-slots 545 are formed at the top of the base plate 1. A T-shaped rod 546, adapted to the T-slot 545, is fixed to the bottom of each rack 543, providing guidance and limiting for the racks 543, thus making them more stable during sliding. Each rack 543 meshes with the gear 542, and each rack 543 is fixedly connected to a corresponding moving block 53. A motor 544 is fixed to the bottom of the base plate 1. The output end of the motor 544 is fixedly connected to the bottom end of the drive shaft 541. In use, starting the forward and reverse motor 544 drives the drive shaft. When drive shaft 541 rotates, it drives gear 542 to rotate. Since both racks 543 are meshed with gear 542, when drive shaft 541 rotates, it can drive two moving blocks 53 to move back and forth. After moving, the moving blocks 53 can drive the extrusion cylinder 51 to move through the slide rod 52 fixed on one side wall. Therefore, when the two extrusion cylinders 51 move synchronously in opposite directions, the dust collected inside the collection box 2 can be extruded into blocks. In addition, since the synchronous reverse movement distance of the two racks 543 is controlled by the rotation of motor 544, there will be no situation where the racks 543 disengage from gear 542 after excessive movement. At the same time, in order to protect the drive mechanism 54, a protective cover is installed on the base plate 1 for protection, but the protective cover is not shown in the figure.

[0033] like Figure 4As shown, in some embodiments, the collection box 2 is also equipped with a tapping assembly 6 for cleaning the filter assembly 4. The tapping assembly 6 includes two guide rails 61 fixed to the outer wall of the collection box 2. A reciprocating rod 62 is slidably connected to each guide rail 61. A tapping rod 63 is fixed to one side wall of each reciprocating rod 62. The bottom end of each tapping rod 63 slides through the collection box 2 and extends into its interior. Two springs 64 are fixed to the top of the collection box 2. The top ends of each spring 64 are fixedly connected to the corresponding reciprocating rod 62. Each moving block 53 is fixed with a pushing block 65 adapted to the reciprocating rod 62. In use, when the moving block 53 moves... When block 53 moves, it drives push block 65 to move. At this time, when push block 65 moves laterally, it squeezes reciprocating rod 62 to move downward. When reciprocating rod 62 moves downward, spring 64 is compressed. When reciprocating rod 62 moves downward, it drives tapping rod 63 to move downward to tap the filter screen 44 in filter assembly 4. When push block 65 releases the restriction on reciprocating rod 62, the resetting force of compressed spring 64 can drive reciprocating rod 62 to move upward and reset. Therefore, the purpose of cleaning can be achieved by reciprocating tapping of filter screen 44 by reciprocating up and down tapping rod 63.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
