Description

Technical Field

[0001] The utility model relates to the field of dust removal equipment, in particular to a dust removal equipment. Background Art

[0002] Coal mining generates a large amount of dust. This dust not only pollutes the environment but also poses a threat to workers' health. Therefore, to protect worker health and reduce environmental pollution, coal mines require effective dust removal equipment. Cyclone dust collectors, with their simple structure and high dust removal efficiency, are a common type of dust removal equipment used in coal mines. Coal transportation and processing, such as in coal yards and coal washeries, also generate large amounts of dust. Managing this dust is a crucial aspect of mechanical and electrical work in coal mines. Cyclone dust collectors effectively remove dust from these processes, protecting the environment and worker health.

[0003] In the prior art, when a cyclone dust collector is used to remove dust from coal mines, in order to further improve the dust removal effect, a dust filter is installed on the inner wall of the exhaust pipe on the top of the cyclone dust collector to achieve the purpose of secondary dust removal and filtration of dust in the gas during exhaust. However, since the dust filter is mostly fixed to the inner wall of the exhaust pipe by bolts, it is inconvenient to disassemble the dust filter when the subsequent dust filter needs to be cleaned or replaced after a long period of use. This not only brings inconvenience to the disassembly and replacement of the dust filter in the exhaust pipe of the cyclone dust collector, but also affects the dust treatment effect of the cyclone dust collector.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 5 As shown, a dust removal device includes a cyclone dust collector 1, an air inlet pipe 2 is provided on the left side wall of the cyclone dust collector 1, and an exhaust pipe 3 is provided on the top surface of the cyclone dust collector 1;

[0022] The dust removal principle of the cyclone dust collector 1 is as follows: the dust-laden airflow enters the cylinder of the cyclone dust collector 1 through the air inlet pipe 2 in a tangential direction at a certain speed. After entering the cylinder, the airflow is blocked by the cylinder wall and forced to make a circular motion, forming a downward spiral rotating airflow. During the rotation process, the dust particles in the airflow are thrown to the cylinder wall by the centrifugal force. The heavier dust particles are gradually deposited on the cylinder wall under the action of centrifugal force and move downward along the wall, and finally deposited in the cone part and the ash hopper. This process realizes the separation of dust particles and airflow. After the dust particles are separated, the purified gas rises along the central axis. These gases leave the dust collector through the exhaust pipe 3 at the top, thus completing the entire dust removal process; the top of the exhaust pipe 3 The end is fixedly connected to the dust filter 4 through the fixing mechanism 5 on both sides, and the fixing mechanism 5 includes a concave block 9, a flip plate 14, a fixed block 18, a pressure plate 20, a clamping rod 22 and a threaded knob 24. The concave blocks 9 are fixedly connected to both sides of the outer wall of the exhaust pipe 3, and the flip plate 14 is movably connected to the concave block 9 through the rotating rods 15 at the bottom ends of both sides. The fixed block 18 is fixedly connected to the top of the outer wall of the flip plate 14, and the pressure plate 20 is movably connected to the vertical opening 16 of the side wall of the fixed block 18 through the sliders 21 on both sides.

Furthermore, the positioning groove 8 provided on the inner wall of the sealing ring groove 6 enables the dust filter 4 to be positioned and installed on the top surface of the exhaust pipe 3.

[0024] like Figure 4 As shown, a sealing pressure ring 11 is fixedly installed on the bottom surface of the dust removal filter 4, and the outer wall of the sealing pressure ring 11 is fixedly connected with a positioning block 12 corresponding to the positioning groove 8. A group of symmetrical card holes 13 are also provided on the top surface of the dust removal filter 4. The dust removal filter 4 will be positioned and installed on the top surface of the exhaust pipe 3 through the positioning blocks 12 on both sides of the outer wall of the sealing pressure ring 11, and the sealing pressure ring 11 will squeeze the sealing ring 7 after entering the sealing ring groove 6 to achieve the sealing of the dust removal filter 4 installed on the top surface of the exhaust pipe 3, so as to prevent the gas from being discharged from the connection during exhaust and not being subjected to secondary filtration and dust removal treatment, and the card holes 13 provided on the top surface of the dust removal filter 4 are used to cooperate with the fixed use of the fixing mechanism 5;

[0025] like Figure 3 and Figure 5As shown, a group of symmetrical concave blocks 9 are fixedly mounted on the outer wall of the exhaust pipe 3, and rotation holes 10 are respectively opened on both sides of the inner wall of the notch of the concave block 9. Rotation rods 15 are respectively fixedly mounted on the bottom ends of the two side walls of the flip plate 14, and the rotation rods 15 are movably mounted in the rotation holes 10. The rotation rods 15 rotate in the rotation holes 10 opened on the concave block 9 to realize the flip operation of the flip plate 14 when the dust filter 4 is fixed;

[0026] like Figure 5 As shown, a vertical opening 16 is provided on the side wall of the flip plate 14, and slide grooves 17 are provided on both sides of the inner wall of the vertical opening 16. A fixing block 18 is fixedly installed on the top of the outer wall of the flip plate 14, and a screw hole 19 is provided on the top surface of the fixing block 18. The screw hole 19 provided on the fixing block 18 allows the threaded knob 24 to be threadedly connected with the screw hole 19 and the threaded knob 24 can be rotated. The vertical opening 16 provided on the flip plate 14 and the slide grooves 17 provided on both sides of the inner wall of the vertical opening 16 enable the pressure plate 20 to move up and down in the vertical opening 16 through the sliders 21 on both sides.

[0027] like Figure 5 As shown, the pressure plate 20 is movably installed in the vertical opening 16, and sliders 21 are fixedly installed on the two side walls of the pressure plate 20, and the sliders 21 are movably installed in the slide grooves 17.

A convex groove 23 is provided on the outer side of the top surface of the pressure plate 20, and a threaded knob 24 is threadedly connected to the screw hole 19, and a rotating block 25 is fixedly installed on the bottom surface of the threaded knob 24 and is limited and movably installed in the convex groove 23. After the flip plate 14 completes the flipping operation to the inside, the threaded knob 24 is rotated to rotate. The button 24 causes the threaded knob 24 to rotate in the screw hole 19, and drives the rotating block 25 to rotate in the convex groove 23, and then pushes the pressure plate 20 downward through the rotating block 25, so that when the pressure plate 20 moves in the vertical opening 16, the sliders 21 on both sides of the pressure plate 20 slide in the slide groove 17 until the pressure plate 20 is pressed on the top surface of the dust filter 4, and the sliders 21 on the bottom surface of the pressure plate 20 are inserted into the card holes 13 opened on the top surface of the dust filter 4, thereby achieving the purpose of quickly installing the dust filter 4 on the top surface of the exhaust pipe 3 and cooperating with the cyclone dust collector 1 for secondary filtering and dust removal.

[0028] It should be noted that the present invention is a dust removal device. When the dust filter 4 is installed on the top surface of the exhaust pipe 3 to be used in conjunction with the cyclone dust collector 1, during installation, the sealing pressure ring 11 installed on the bottom surface of the dust filter 4 is pressed into the sealing ring groove 6 opened on the top surface of the exhaust pipe 3, and in the process of making the sealing pressure ring 11 enter the sealing ring groove 6, the positioning blocks 12 installed on both sides of the outer wall of the sealing pressure ring 11 are aligned with the positioning groove 8 opened on the inner wall of the sealing ring groove 6, and the positioning blocks 12 are correspondingly entered into the positioning groove 8, so that the dust filter 4 can be quickly positioned and installed on the top surface of the exhaust pipe 3, and the sealing pressure ring 11 on the bottom surface of the dust filter 4 squeezes the inner wall of the sealing ring groove 6 in the sealing ring groove 6. After the sealing ring 7 is installed on it, the sealing of the connection between the dust filter 4 and the exhaust pipe 3 can be ensured to prevent the gas from being discharged from the connection during exhaust and not being filtered and dust-removed for the second time. Then, the flip plates 14 on both sides of the exhaust pipe 3 are manually flipped inward in turn. The rotating rods 15 installed at the bottom ends of both sides of the flip plate 14 will rotate in the rotating holes 10 opened on both sides of the inner wall of the recess of the concave block 9 installed on one side. After the flip plate 14 can no longer be flipped, hold the flip plate 14 and rotate the threaded knob 24 on the top surface of the fixing block 18 on the outer side wall of the flip plate 14. The threaded knob 24 will realize the threaded rotation operation in the screw hole 19 opened on the top surface of the fixing block 18, and the threaded knob 24 will bring The rotating block 25 installed at the bottom end of the movement is limitedly rotated in the convex groove 23 opened on the outer part of the top surface of the pressure plate 20, and after continuously rotating the threaded knob 24, the threaded knob 24 will push the pressure plate 20 downward through the rotating block 25, so that the pressure plate 20 moves downward in the vertical opening 16 opened on the side wall of the flip plate 14, and the sliders 21 installed on both sides of the pressure plate 20 will slide in the sliding grooves 17 opened on both sides of the inner wall of the vertical opening 16 until the pressure plate 20 is pressed on one side of the top surface of the dust filter 4 so that the threaded knob 24 can no longer be rotated. At the same time, the clamping rod 22 installed on the inner side of the bottom surface of the pressure plate 20 will be correspondingly inserted into the clamping hole 13 opened on the top surface of the dust filter 4, so that the dust filter 4 can be quickly removed. It is quickly installed and fixed to the top surface of the exhaust pipe 3. When the dust filter 4 needs to be replaced after a long period of use to ensure the secondary dust removal and filtering effect of the subsequent cyclone dust collector 1 during dust removal, when disassembling the dust filter 4, the threaded knob 24 is rotated in the opposite direction to drive the rotating block 25 installed in the convex groove 23 through the limiting activity to drive the pressure plate 20 to move upward, so that the clamping rod 22 on the bottom surface of the pressure plate 20 is moved out of the clamping hole 13, and then the flip plate 14 is flipped outward to remove the dust filter 4 from the top surface of the exhaust pipe 3, thereby facilitating the disassembly, assembly and replacement of the dust filter 4 on the cyclone dust collector 1 and ensuring the secondary dust treatment effect of the cyclone dust collector 1.

[0029] The above merely is preferred embodiment of the present utility model and is not used for limiting the present utility model, although the present utility model is described in detail with reference to the foregoing embodiment, however, can make various improvements and can replace the components therein with equivalent in the case of not departing from the scope of the present utility model, or make equivalent replacement to part technical features, all should be contained in the protection scope of the present utility model in the spirit and principle of the present utility model.
