Description

Technical Field

[0001] The utility model relates to the technical field of crushing and dust removal, in particular to an iron ore crushing and dust removal device. Background Art

[0002] Dust removal equipment is used in iron ore crushing to protect the working environment and personnel health. If uncontrolled, the large amounts of fine dust generated by crushing operations can expose workers to high concentrations of dust for long periods of time, leading to respiratory illnesses. A healthy environment also improves work comfort and efficiency. Furthermore, it complies with environmental regulations, reduces dust pollution to the atmosphere, preserves ecological balance, and avoids penalties for non-compliance. Furthermore, it protects equipment and extends its service life by preventing dust accumulation that affects equipment operation, dissipates heat, and increases wear, and reduces the corrosion caused by corrosive dust. Furthermore, it improves product quality by preventing dust from entering and reducing purity.

[0003] Traditional iron ore crushing and dust removal systems typically utilize multiple mechanisms working in concert. A dust hood, installed at the dust-generating site of the crusher, collects the dust. Ventilation ducts connect the dust hood to subsequent equipment, conveying the dust-laden gas. Cyclone dust collectors use centrifugal force to separate larger dust particles, while bag filters filter fine dust through filter bags. Cleaning devices such as vibrators or backflush devices remove accumulated dust from the filter bags. Induced draft fans power the flow of dust-laden gas, while dust removal devices discharge the collected dust. A control system manages the operation of the entire system, including fan start-up and shutdown, as well as cleaning cycles, to ensure stable and efficient operation and achieve excellent dust removal results.

[0004] The induced draft fan in the traditional iron ore crushing and dust removal device cannot adjust the suction speed, which will bring many disadvantages. First, it is impossible to flexibly adjust the suction force according to the actual amount of dust generated, which causes energy waste when the amount of dust generated is small and increases operating costs. Secondly, when the amount of dust generated suddenly increases, the suction speed cannot be increased in time, which will cause some dust to not be effectively inhaled, resulting in an increase in the dust concentration in the working environment, affecting the health of workers and the quality of the working environment. Moreover, the inability to adjust the suction speed will also make the pressure inside the equipment unstable, affecting the operating efficiency and stability of the entire dust removal system, and increasing the maintenance cost and failure risk of the equipment. For this reason, an iron ore crushing and dust removal device is proposed to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1 、 Figure 2 and Figure 3 The utility model provides an embodiment of an iron ore crushing and dust removal device, comprising a base 6, a pillar 32 fixedly connected to the top of the base 6, a first shell 1 fixedly connected to the top of the pillar 32, a connecting block 12 fixedly connected to the inner wall of the first shell 1, a hydraulic cylinder 11 fixedly connected to the side wall of the connecting block 12, a wrench 14 fixedly connected to the output end of the hydraulic cylinder 11, a first hollow column 13 fixedly connected to the side wall of the wrench 14, a first hollow column 13 rotatably connected to the outer wall of the first hollow column 13, a connecting column 18 fixedly connected to the outer wall of the first hollow column 13, a hollow plate 15 rotatably connected to the outer wall of the connecting column 18, a fan blade 16 fixedly connected to the inside of the hollow plate 15, a rotating disk 20 fixedly connected to the side wall of the fan blade 16, and a baffle 19 fixedly connected to the inner wall of the first hollow column 13.

[0035] Specifically, the output end of hydraulic cylinder 11 drives wrench 14 to rotate. During this process, the force exerted on wrench 14 further drives the ring 17 to rotate. Simultaneously, the rotation of ring 17 drives hollow plate 15, causing it to swing. Furthermore, the force exerted on hollow plate 15 drives blades 16 to rotate. Notably, each blade 16 rotates on the outer wall of rotating disk 20. Furthermore, by connecting and securing them with bars 19, the suction speed can be flexibly adjusted, meeting the dust removal requirements under different working conditions.

[0036] Reference Figure 1 、 Figure 4 and Figure 5The top of the base 6 is fixedly connected to the cabinet body 8, the inner wall of the cabinet body 8 is slidably connected to the pull-out cabinet 7, the side wall of the pull-out cabinet 7 is fixedly connected to the card block 21, the top of the base 6 is fixedly connected to the hollow block 25, the inner wall of the hollow block 25 is slidably connected to the sliding plate 23, the sliding plate 23 is rotatably connected to the rotating plate 27, the inner wall of the hollow block 25 is fixedly connected to the fixed column 26, and the outer wall of the fixed column 26 is provided with a first spring 24, one end of the first spring 24 is fixedly connected to the side wall of the first plywood 22, the top of the sliding plate 23 is fixedly connected to the first plywood 22, and the inner wall of the first plywood 22 is provided on the outer wall of the card block 21.

[0037] Specifically, dust falls from the dust outlet 9 and falls into the interior of the drawer 7. Then, after the dust inside the drawer 7 accumulates to a specified amount, the drawer 7 is pushed, and the force exerted on the drawer 7 drives the block 21 to move. At the same time, the movement of the block 21 presses one side against the inner wall of the first clamping plate 22. Then, after the first clamping plate 22 is subjected to force, the sliding plate 23 slides inside the hollow block 25. Moreover, the sliding plate 23 drives the internal rotating plate 27 to rotate after being subjected to force. Moreover, an irregular slot is provided on one side of the hollow block 25, and the rotating plate 27 is stuck in the inside of the slot. Then, after the rotating plate 27 rotates, the first spring 24 is driven to release it, and the sliding plate 23 can be reset again, so that it moves to the top of the hollow block 25, thereby achieving the effect of pressing and self-locking, which facilitates the operation and use of the drawer 7.

[0038] Reference Figure 1 、 Figure 2 and Figure 6 The side wall of the first shell 1 is provided with a duct assembly, which is used to connect the dust suction function. The duct assembly includes a fixed cover 2, the side wall of the fixed cover 2 is fixedly connected to the side wall of the first shell 1, and a connecting channel 3 is fixedly connected inside the fixed cover 2. One end of the connecting channel 3 is fixedly connected to the dust suction port 4. The top of the first shell 1 is fixedly connected to a support block 28, and the side wall of the support block 28 is fixedly connected to a second hollow column 29. The inner wall of the second hollow column 29 is provided with a second spring 31, and one end of the second spring 31 is fixedly connected to a second splint 30. The inside of the first shell 1 is fixedly connected to an axial flow fan 10, and the side wall of the axial flow fan 10 is fixedly connected to the side wall of the first hollow column 13. A dust outlet 9 is opened on the side wall of the first shell 1, and an adjusting device 5 is fixedly connected to the top of the base 6.

[0039] Specifically, when the iron ore crushing and dust removal device is used, suction force is first generated by the axial flow fan 10. This powerful suction force can effectively draw the surrounding dust-laden air into the interior of the device. Subsequently, the range of dust entry is expanded by the fixed cover 2, which greatly improves the dust collection efficiency. Next, the connecting channel 3 plays an important role. It can not only adjust its position, but also has a certain elastic force, which can better adapt to different working scenarios. At the same time, dust removal is carried out through the dust suction port 4 to ensure that the dust is effectively captured and processed. In addition, when the connecting channel 3 is not in use, the second splint 30 is slid into the inner wall of the second splint 30. At this time, after the second splint 30 is subjected to force, it will drive the second spring 31 of the outer wall to move toward one end of the second hollow column 29, thereby achieving the effect of stably clamping the connecting channel 3 and ensuring the safety and stability of the device in the non-working state.

[0040] Working principle: When using the iron ore crushing and dust removal device, first, the axial flow fan 10 is used to generate suction force, and then the fixed cover 2 is used to expand the range of dust entry, and then the position is adjusted through the connecting channel 3, and the connecting channel 3 has a certain telescopic force, and dust is removed through the dust suction port 4. At the same time, when the connecting channel 3 is not in use, the second clamping plate 30 is slid into the inner wall of the second clamping plate 30, and the second clamping plate 30 is subjected to force and drives the second spring 31 of the outer wall to move toward one end of the second hollow column 29, thereby achieving the effect of clamping the connecting channel 3. Next, the output end of the hydraulic cylinder 11 drives the wrench 14 to rotate, and the force of the wrench 14 drives the ring 17 to rotate, and the rotation of the ring 17 drives the hollow plate 15 to swing, and the hollow plate 15 drives the fan blades 16 to rotate after being subjected to force, and each fan blade 16 rotates on the rotating disk 2 The outer wall of 0 is connected and fixed by the baffle 19, which achieves the effect of adjusting the suction speed. The dust is then dropped into the interior of the drawer cabinet 7 through the dust outlet 9. After the dust inside the drawer cabinet 7 accumulates to a specified amount, the drawer cabinet 7 is pushed and the force of the drawer cabinet 7 drives the card block 21 to move. At the same time, the movement of the card block 21 presses one side against the inner wall of the first clamping plate 22. After the force of the first clamping plate 22 is applied, the sliding plate 23 slides inside the hollow block 25, and the sliding plate 23 drives the internal rotating plate 27 to rotate after the force is applied. An irregular card groove is provided on one side of the hollow block 25, and the rotating plate 27 is stuck in the inside of the card groove. After the rotation of the rotating plate 27, the first spring 24 is driven to release it, and the sliding plate 23 can be reset again, so that it moves to the top of the hollow block 25, achieving the effect of press self-locking.
