Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a bag dust collector for mineral powder. Background Art

[0002] The bag dust collector for mineral powder, also known as the bag dust remover for mineral powder or the bag dust collector for mines, is an efficient dust removal device widely used in industries such as mines, building materials, and chemicals. When the dust-containing gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material (filter bag), the dust is retained on the outer surface of the filter bag, and the purified gas enters the upper box body through the filter bag opening and is finally discharged from the air outlet.

[0003] As the filtration time prolongs, the dust layer on the filter bag continuously thickens, and the resistance of the dust removal device also continuously rises. When the device resistance rises to the set value, the dust cleaning device starts to clean the dust. During the dust cleaning process, the dust is discharged through the dust outlet at the bottom of the dust collector. When the dust is discharged, it will disperse everywhere and is easily inhaled by the workers who are cleaning. Therefore, a bag dust collector for mineral powder is proposed.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution for a bag type dust collector for mineral powder, including a dust collector body 1, a support 2 is provided on the dust collector body 1, an air inlet 3 is provided on one side of the dust collector body 1, a dust outlet 4 is fixedly installed at the bottom of the dust collector body 1, a mixing chamber body 5 is connected to the dust outlet 4, a mixing mechanism 6 is provided on the mixing chamber body 5, a discharging mechanism 7 is provided at the bottom of the mixing chamber body 5. The driving motor 601 can drive the mixing mechanism 6 and the discharging mechanism 7 to operate. When the mixing mechanism 6 operates, it will mix the dust and glue to form a paste, preventing the dust from spreading everywhere during the dust cleaning process. The discharging mechanism 6 will extrude the paste formed by the dust out of the perforated end cover 707 to form large dust particles, which is convenient for users to collect and process.

[0022] As Figure 2 and Figure 3As shown, a mixing chamber 5 is connected to the dust outlet 4. The mixing mechanism 6 includes a cylinder block 607 fixedly installed on the mixing chamber 5. A spring 606 is provided inside the cylinder block 607. A piston 605 is movably installed inside the cylinder block 607. A spray head 609 is connected to the cylinder block 607. A driving motor 601 is fixedly provided above the cylinder block 607. A driving shaft 603 is fixedly installed at the output end of the driving motor 601. A cam 604 is fixedly installed on the driving shaft 603. A motor bracket 602 is provided at the output end of the driving motor 601. A liquid inlet 608 is opened on the side wall of the cylinder block 607. One-way valves are provided in both the liquid inlet 608 and the spray head 609.

[0023] Specifically, the driving motor 601 can drive the cam 604 to move back and forth. When the cam 604 moves backward, glue will be sucked into the cylinder block 607. When the piston 605 moves forward, the glue in the cylinder block 607 will be squeezed into the spray head 609. The glue squeezed into the spray head 609 will be sprayed into the mixing chamber 5 to mix with the dust, forming a paste, which can prevent the dust from spreading everywhere during the dust cleaning process.

[0024] As Figure 3 and Figure 4 shown, the discharging mechanism 7 includes a discharging pipeline 706 fixedly installed at the bottom of the mixing chamber 5. A squeezing screw 705 is movably installed inside the discharging pipeline 706. A perforated end cover 707 is provided at the end of the discharging pipeline 706. A speed reducer 702 is provided on one side of the squeezing screw 705. An input shaft 701 and an output shaft 703 are provided on the speed reducer 702. Helical gears 704 are provided on both the output shaft 703 and the squeezing screw 705, and the two sets of helical gears 704 are meshed together.

[0025] Specifically, after the dust forms a paste, it will fall into the discharging pipeline 706. The driving motor 601 can drive the driving shaft 603 to rotate. After the driving shaft 603 rotates, it will drive the input shaft 701 to rotate. After being decelerated by the speed reducer 702, the output shaft 703 will drive the squeezing screw 705 to rotate slowly. After the squeezing screw 705 rotates slowly, it will squeeze the paste out of the perforated end cover 707, forming large dust particles, which are convenient for users to collect and process.

[0026] Working principle: When in use, the dust bag in the dust collector body 1 can filter the dust in the gas. The filtered dust will be discharged through the dust outlet 4. The dust discharged through the dust outlet 4 will fall into the mixing chamber 5. After the dust falls into the mixing chamber 5, the drive motor 601 can be started. There is a pipeline on the liquid inlet 608 of the cylinder block 607, and the end of the pipeline is below the liquid level of the glue. Starting the drive motor 601 will drive the drive shaft 603 to rotate. After the drive shaft 603 rotates, it will drive the cam 604 to rotate. During the rotation of the cam 604, it will drive the piston 605 to reciprocate. Since one-way valves are provided in both the liquid inlet 608 and the nozzle 609, the one-way valve in the liquid inlet 608 only allows the liquid to enter the cylinder block 607 through the liquid inlet 608, and the one-way valve in the nozzle 609 only allows the liquid in the cylinder block 607 to be sprayed out through the nozzle 609. Therefore, when the piston 605 returns to its original position, the glue will be sucked into the cylinder block 607. When the piston 605 moves forward, the glue in the cylinder block 607 will be squeezed into the nozzle 609. The glue squeezed into the nozzle 609 will be sprayed into the mixing chamber 5 and mixed with the dust to form a paste. After the dust forms a paste, it will fall into the discharge pipeline 706. At this time, the drive shaft 603 will drive the input shaft 701 to rotate. After being decelerated by the speed reducer 702, the output shaft 703 will drive the extrusion screw 705 to rotate slowly. After the extrusion screw 705 rotates slowly, it will squeeze the paste to the front end of the discharge pipeline 706. The paste squeezed to the front end of the discharge pipeline 706 will be discharged through the small holes on the perforated end cover 707, which is convenient for users to collect and process. During the whole dust cleaning process, the dust can be prevented from floating around.
