Description

Technical Field

[0001] This utility model relates to the field of dual-shaft shredders, specifically a dual-shaft shredder with double-sided motors. Background Technology

[0002] The dual-shaft shredder with dual motors is an industrial crushing device that uses counter-rotating dual-shaft cutter rollers. It generates shearing force through the counter-rotating of two independent cutter shafts, which, in conjunction with fixed cutters, shreds materials. This equipment features low speed, high torque, and low noise, and can process various waste materials such as metals, plastics, and rubber, with controllable output particle size. The dual-shaft motors provide powerful performance, the equipment frame is robust and durable, and it is easy to operate and maintain. It is widely used in waste recycling, resource regeneration, and metal recovery.

[0003] Chinese patent CN106076548B discloses a dual-shaft shredder, including a housing and blades installed inside the housing. The housing forms a crushing chamber, and both ends of the crushing chamber are provided with spaced-apart mounting plates and partitions. The mounting plates are encapsulated on the outside of the partitions, and a first gap communicating with the crushing chamber is formed between the mounting plates and the partitions. The cutting blades of the cutting blades are distributed in a spiral pattern on the blade shaft. When shredding materials, the blade shaft rotates once, and multiple cutting blades can cut at different points on the material, resulting in strong cutting force.

[0004] The aforementioned patented dual-shaft shredder generates dust during the shredding process. The dust flows out from the material input point and the shredded material discharge point. Continuous shredding over a long period of time will pollute the environment where the equipment is located, resulting in a large amount of dust around the equipment. This dust can easily be inhaled by workers near the equipment, affecting their health. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-motor dual-shaft shredder, which can absorb dust at the source through the first and second transmission pipes and retain the dust in a detachable dust collection bag for easy subsequent cleaning, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-sided motor dual-shaft shredder, comprising a crushing frame, a collecting frame at the upper end of the crushing frame, and a discharging frame at the lower end of the crushing frame. A dividing plate is welded to one side inside both the collecting frame and the discharging frame. A first transmission pipe is sealed on the side of the collecting frame corresponding to the outside of the dividing plate, and a second transmission pipe is sealed on the side of the discharging frame corresponding to the outside of the dividing plate. The first and second transmission pipes are sealed together by a connecting pipe. A fan is provided on one side of the lower end of the connecting pipe. The fan can draw in gas and send dust along with the gas into a dust collection bag, allowing for temporary storage of dust for subsequent collection and processing.

[0007] Preferably, a collection frame is provided between the fan and the connecting pipe, one end of the connecting pipe extends into the inside of the collection frame, and a dust collection bag is provided inside the collection frame so that dust can pass through the inside of the collection frame and be collected when the fan extracts dust.

[0008] Preferably, the upper end of the dust collection bag is provided with an annular third connecting ring, and the upper end of the third connecting ring is provided with a first connecting ring around the outside of the second connecting ring. The first connecting ring and the third connecting ring are welded and fixed together. The first connecting ring and the second connecting ring are threaded together. The connection between the first connecting ring and the second connecting ring facilitates the installation and disassembly of the dust collection bag.

[0009] Preferably, an annular rubber pad is provided between the third connecting ring and the second connecting ring, and the rubber pad is connected to the third connecting ring by glue. The rubber pad can fill the space between the second connecting ring and the third connecting ring, which can improve the stability of the dust collection bag installation, facilitate gas extraction, and facilitate the delivery of dust into the dust collection bag.

[0010] Preferably, the collection frame is sealed to the extraction position of the fan, and the gas at the collection frame position can be directly extracted by the fan, which facilitates the extraction, collection and treatment of dust.

[0011] Preferably, a sealing plate is provided at the front end of the outer side of the collection frame, and an installation groove is provided around the inner side of the sealing plate facing the collection frame. The inner side of the installation groove is connected to the outer slot of the collection frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features dividing plates on the inner sides of both the material collection frame and the discharge frame for crushed material. These dividing plates restrict and protect the gas extraction points of the first and second transmission pipes. The dust generated during the crushing process flows out from the collection and discharge frames, and is absorbed at its source by the first and second transmission pipes, remaining in a removable dust collection bag for easy cleaning. This process collects dust generated during crushing without extracting the material to be crushed or the crushed material, thus improving the cleanliness of the environment during equipment use.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1 and Figure 2As shown, a dual-shaft shredder with a double-sided motor in this embodiment includes a crushing frame 3. A collection frame 1 is provided at the upper end of the crushing frame 3, and a discharge frame 2 is provided at the lower end of the crushing frame 3. The material to be crushed is fed into the collection frame 1, crushed at the position of the crushing frame 3, and discharged from the position of the discharge frame 2. The dust generated during the crushing process will also drift out directly from the positions of the collection frame 1 and the discharge frame 2.

[0023] When crushing the material fed into the collection frame 1, a pair of crushing frames 3 are arranged horizontally inside the crushing frame 3. The two crushing frames 3 are distributed horizontally inside the crushing frame 3. The material to be crushed falling from the collection frame 1 can come into contact with the pair of rotating cutter rollers 4 and be crushed.

[0024] In order to extract dust directly from the dust emission point and prevent dust from falling around the equipment, a dividing plate 5 is provided on one side inside the material collection frame 1 and the material discharge frame 2. The dividing plate 5 is welded and fixed to the material collection frame 1 and the material discharge frame 2 respectively. The dividing plate 5 can prevent the material fed into the material collection frame 1 from being extracted directly, and also prevent the crushed material falling from the position of the material discharge frame 2 from being extracted.

[0025] Furthermore, a first transmission pipe 7 is provided on one side of the material collection frame 1 corresponding to the outside of the dividing piece 5, and a second transmission pipe 8 is provided on one side of the material discharge frame 2 corresponding to the outside of the dividing piece 5. The second transmission pipe 8 is sealed to the material discharge frame 2, and the first transmission pipe 7 is sealed to the material collection frame 1. Dust drifting out from the dividing piece 5 can be extracted through the first transmission pipe 7 and the second transmission pipe 8, which facilitates the collection of dust.

[0026] When dust needs to be collected and gathered, the first transmission pipe 7 and the second transmission pipe 8 are sealed together by a connecting pipe 9. A fan 14 is provided on one side of the lower end of the connecting pipe 9. By drawing the dust from the position of the connecting pipe 9 by the fan 14, the dust in the collection frame 1 and the discharge frame 2 can be drawn at the same time, which can achieve efficient dust removal and dust collection.

[0027] To collect dust effectively and reduce damage to the fan 14, a collection frame 10 is installed between the fan 14 and the connecting pipe 9. One end of the connecting pipe 9 extends into the collection frame 10, and a second connecting ring 19 is installed at one end of the connecting pipe 9 inside the collection frame 10. Figure 3 As shown, a dust collection bag 15 is provided inside the collection box 10. After the gas and dust are drawn by the fan 14, the dust will be retained inside the dust collection bag 15, while the gas can be discharged directly.

[0028] Furthermore, to facilitate the installation of the dust collection bag 15, an annular third connecting ring 21 is provided at the upper end of the dust collection bag 15, and the third connecting ring 21 is connected to the dust collection bag 15 by glue. A first connecting ring 18 is provided around the outside of the second connecting ring 19 at the upper end of the third connecting ring 21, and the first connecting ring 18 is welded and fixed to the third connecting ring 21. The first connecting ring 18 and the second connecting ring 19 are threaded together. By rotating the position of the first connecting ring 18, the third connecting ring 21 can be twisted, and the lower end of the dust collection bag 15 can be twisted and removed.

[0029] In addition, to improve the sealing effect between the third connecting ring 21 and the second connecting ring 19, such as Figure 6 As shown, an annular rubber pad 20 is provided between the third connecting ring 21 and the second connecting ring 19, and the rubber pad 20 is connected to the third connecting ring 21 by glue. After the first connecting ring 18 rotates and the third connecting ring 21 moves toward the second connecting ring 19, the rubber pad 20 can fill the space between the second connecting ring 19 and the third connecting ring 21 to improve the sealing effect.

[0030] The collection frame 10 is sealed to the extraction position of the fan 14. The extraction by the fan 14 allows dust and air to be sent into the collection frame 10 together for subsequent dust filtration.

[0031] In order to seal the front end of the collection frame 10 and facilitate the installation and removal of the dust collection bag 15 inside, a sealing plate 11 is provided at the front end of the outer side of the collection frame 10. An installation groove 17 is provided around the inner side of the sealing plate 11 facing the collection frame 10, and the interior of the installation groove 17 is connected to the outer slot of the collection frame 10. After the sealing plate 11 is placed over the front end of the collection frame 10, the front end of the collection frame 10 can be sealed by the sealing plate 11.

[0032] Furthermore, such as Figure 4 As shown, the collection frame 10 has mounting holes 16 on both sides facing the sealing plate 11. The mounting holes 16 penetrate the sealing plate 11 and are embedded inside the collection frame 10. A bolt 12 is installed inside the mounting hole 16. The bolt 12 penetrates the mounting hole 16 inside the sealing plate 11 and is threadedly engaged with the recessed mounting hole 16 inside the collection frame 10. The sealing plate 11 can be fixed by rotating the bolt 12 and embedding it into the mounting hole 16.

[0033] In addition, a handle 13 is provided on the outer wall of the sealing plate 11, and the handle 13 is sealed to the sealing plate 11. The sealing plate 11 can be easily installed and removed by gripping the handle 13.

[0034] To avoid the material to be crushed and the crushed material being directly extracted, such as Figure 5As shown, a grid 6 is horizontally arranged at one end of the inner side of the dividing plate 5, and the grid 6 is welded and fixed to the dividing plate 5. The grid 6 can restrict the material to be crushed and the crushed material, preventing it from being directly extracted and avoiding affecting the normal use of the first transmission pipe 7 and the second transmission pipe 8.

[0035] Working principle: When using the device to crush materials, the material is fed into the collection frame 1, passes through two rotating cutter rollers 4, and is discharged from the discharge frame 2. During the discharge process, dust generated from the placement of the materials and the crushing process is discharged from the upper end of the collection frame 1 and the lower end of the discharge frame 2. The blower 14 is started, and the output shaft of the blower 14 draws dust from the first transmission pipe 7 and the second transmission pipe 8 through the connecting pipe 9. The dust discharged from the upper end of the collection frame 1 and the lower end of the discharge frame 2 is drawn and collected in the connecting pipe 9. After the dust is collected in the connecting pipe 9, it enters the dust collection bag 15, where it is filtered and collected. The gas is drawn by the blower 14 and discharged directly. When the dust bag 15 needs to be cleaned and replaced, rotate the bolt 12 used to remove the sealing plate 11 from the mounting hole 16. After removing the sealing plate 11, the dust bag 15 will be exposed. Rotate the first connecting ring 18. Due to the relative movement between the second connecting ring 19 and the first connecting ring 18, the dust bag 15 will be removed longitudinally. After cleaning the dust bag 15, rotate the first connecting ring 18 again so that the first connecting ring 18 can be installed outside the second connecting ring 19 until the rubber pad 20 connected to the third connecting ring 21 is in contact with the second connecting ring 19. Rotate the bolt 12 again to fix the sealing plate 11 to the front end of the collection frame 10. The fan 14 can then be restarted to resume dust extraction.
