Description

Technical Field

[0001] The utility model relates to the field of dust removal devices, in particular to a dust removal device for asphalt concrete production. Background Technique

[0002] Asphalt concrete is a building material mixed with mineral materials, asphalt and a certain proportion of additives. Asphalt is a high-molecular organic substance derived from petroleum, with good gelling and adhesion properties, and is the main gelling material of asphalt concrete. Mineral materials include sand, gravel, basalt, etc., which are used to form a solid base material after mixing.

[0003] When processing asphalt concrete, asphalt concrete processing equipment is needed to grind and mix the asphalt concrete for production processing. When processing asphalt concrete through the asphalt concrete processing equipment, a large amount of dust will be generated in the asphalt concrete processing equipment, and a dust removal device is needed to remove the dust generated by the asphalt concrete processing equipment.

[0004] However, when the existing dust removal device is in use, it mostly removes dust through a filter component. When the filter component is in use, dust is easily adhered and accumulated on the filter component. After the dust is adhered and accumulated on the filter component, it will affect the filtering effect and efficiency of the filter component for filtering dust, which is not conducive to the use of the filtering device.

[0005] Therefore, we propose a dust removal device for asphalt concrete production. Content of the Utility Model

[0038] The working principle of the utility model is as follows: During use, the support leg 2 is stably placed at the position where it is needed, which helps to stably use the support leg 2. The support leg 2 can support and limit the dust removal box 1 and various components assembled on the dust removal box 1, facilitating the stable use of the dust removal box 1 and various components assembled on the dust removal box 1. The dust removal box 1 can support and limit the baffle 17 and various components assembled on the baffle 17 through the second bolt 16, which helps to stably use the baffle 17 and various components assembled on the baffle 17. The dust removal box 1 can support and limit the air draft tube 11 and various components assembled on the air draft tube 11, facilitating the stable use of the air draft tube 11 and various components assembled on the air draft tube 11.

[0039] Align the asphalt concrete processing equipment mounting ring 14 with the position on the external asphalt concrete processing equipment where installation is required, and install and limit between the asphalt concrete processing equipment mounting ring 14 and the position on the external asphalt concrete processing equipment where installation is required through the first bolt 15. Further, the external asphalt concrete processing equipment is used to grind and mix the asphalt concrete. When the asphalt concrete processing equipment processes the asphalt concrete, a large amount of dust will be generated. Further, turn on the induced draft fan 12. The air draft tube 11 can fix and limit the fixing rod 13, which helps to stably use the fixing rod 13. The fixing rod 13 can fix and limit the induced draft fan 12, facilitating the stable use of the induced draft fan 12. In the state where the induced draft fan 12 is turned on, the induced draft fan 12 can extract the air carrying dust in the external asphalt concrete processing equipment through the air draft tube 11 and the asphalt concrete processing equipment mounting ring 14, so that the air carrying dust forms an air flow and enters the dust removal box 1 through the asphalt concrete processing equipment mounting ring 14 and the air draft tube 11.

[0040] Install the upper end of the second connecting pipe 21 with the external water supply pipe. Further, turn on the water pump 23 on the upper surface of the baffle 17. The baffle 17 can support and limit the water pump 23, which helps to stably use the water pump 23. In the state where the water pump 23 is turned on, the water pump 23 can extract the water in the external water supply pipe through the second connecting pipe 21 and transport the extracted water to the atomizing nozzle 22 through the first connecting pipe 20. The transported water can be atomized and sprayed into the dust removal box 1 through the atomizing nozzle 22. The atomized sprayed water can reduce the dust in the dust removal box 1. The atomized sprayed water mist will carry the dust in the air and fall onto the feeding hopper 10, and then fall into the upper side of the filter mesh plate 9 in the moving frame 4 through the feeding hopper 10. The filter mesh plate 9 can block and filter the dust, and the water will fall to the bottom of the dust removal box 1 through the filter mesh plate 9.

[0041] The gasket 18 can seal and position between the baffle 17 and the dust removal box 1. The air after water mist dust removal will be discharged through the shielding mesh plate 19 on the baffle 17. The baffle 17 can fix and position the shielding mesh plate 19, which is convenient for the stable use of the shielding mesh plate 19. The water falling to the bottom of the dust removal box 1 is discharged through the drain pipe 3. Further, one end of the drain pipe 3 far away from the dust removal box 1 is installed with the equipment used for collecting water outside. After the water at the bottom of the dust removal box 1 is discharged through the drain pipe 3, it will enter the equipment used for collecting water outside.

[0042] When it is necessary to clean the dust blocked and filtered on the filter mesh plate 9, pull the moving frame 4 towards the side away from the air induction cylinder 11 through the push-pull handle 5, so that the moving frame 4 moves towards the side away from the air induction cylinder 11. When the moving frame 4 moves, it can drive the clamping block 7 and the limiting pad 8 to move along the slot 6 on the dust removal box 1 towards the side away from the air induction cylinder 11. The limiting pad 8 can limit between the clamping block 7 and the slot 6 on the dust removal box 1, which is convenient for the stable movement of the moving frame 4 and the clamping block 7, so as to take out the filter mesh plate 9 through the moving frame 4. After taking out the filter mesh plate 9, it is helpful to clean or replace the filter mesh plate 9. After cleaning or replacing the filter mesh plate 9, reset the moving frame 4, the clamping block 7, the limiting pad 8 and the filter mesh plate 9 to the corresponding positions in the dust removal box 1, so as to facilitate the use of the filter mesh plate 9.

[0043] When it is necessary to repair the various components assembled in the dust removal box 1 and on the baffle 17, rotate and remove the second bolt 16. After removing the second bolt 16, the second bolt 16 cancels the limit between the baffle 17 and the dust removal box 1. Further, remove the baffle 17, so as to facilitate the repair of the various components assembled on the baffle 17. After removing the baffle 17, the top of the dust removal box 1 is in an open state, so as to facilitate the repair of the various components assembled in the dust removal box 1, which is helpful for the use of this dust removal device.

[0044] During the use process, it can conveniently remove the dust carried in the air, avoid the dust carried in the air from adhering to the filter components, prevent the dust carried in the air from accumulating, which is helpful to ensure the filtering effect and efficiency of this dust removal device for filtering dust, so as to facilitate the use of this filtering device.
