Description

Technical Field

[0001] This utility model belongs to the technical field of dust treatment equipment, specifically relating to a dust treatment device used in metallurgical mining. Background Technology

[0002] Metallurgical mines continuously generate large amounts of dust during mining, crushing, screening, and transportation processes. This dust, with its complex composition and wide particle size range, not only poses a threat to the health of workers but also easily accumulates on equipment surfaces or inside electrical systems, leading to equipment aging, short circuits, malfunctions, and even fires. Therefore, effective dust removal and air purification in the work area is a crucial aspect of environmental management in metallurgical mines. Currently, widely used dust control equipment includes bag filters, cyclone dust collectors, and wet scrubbers. However, most of these devices are fixed installations, suitable for centralized dust collection in large systems, but lack the ability to quickly deploy to key workstations, temporary sections, or mobile areas, and to rapidly purify the surrounding air. While some small portable dust collectors offer some mobility, in continuous high-dust environments, the filter element is easily clogged by dust adhering to its exterior. Traditional equipment requires frequent shutdowns for manual disassembly and cleaning of the filter element, increasing maintenance workload and replacement frequency. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a dust treatment device used in metallurgical mining, which can automatically and repeatedly clean the dust on the outer nylon pre-filter of the filter element structure to prevent dust accumulation from affecting the negative pressure suction effect and thus affecting the dust suction, filtration and collection.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0036] like Figure 1-6As shown, a dust treatment device used in metallurgical mining includes a dust filter chamber 1. A ventilation duct 2 is connected to the top of the dust filter chamber 1, and a dust collection chamber 3 is connected to the bottom of the dust filter chamber 1. The dust filter chamber 1 is open on all four sides and threadedly fitted with a detachable ventilation plate 4. A horizontal frame 7 is provided inside the dust filter chamber 1. A filter element fixing and releasing mechanism is provided at the top of the horizontal frame 7, and a filter element structure 13 is provided at the top of the filter element fixing and releasing mechanism. A top positioning plate 20 is provided inside the ventilation duct 2, and a suction fan 21 is installed inside the ventilation duct 2. The top of the top positioning plate 20... A motor 23 is installed in the top positioning plate 20. The output end of the motor 23 is connected to a reciprocating lead screw 24. A sliding guide rod 25 is installed at the bottom of the top positioning plate 20. The reciprocating lead screw 24 and the sliding guide rod 25 are connected to the cleaning mechanism 26. The cleaning mechanism 26 includes an outer ring plate 27. An extension groove 28 is provided on the inner side of the outer ring plate 27. An extension plate 29 is inserted into the inner side of the extension groove 28. A spring extension rod 30 is connected between the extension plate 29 and the inner wall of the extension groove 28. A brush 31 is fixedly installed on the inner arc surface of the extension plate 29. A dust collection drawer 32 is inserted into the inside of the dust collection chamber 3.

[0037] When this device is running, the motor 23 can be turned on at regular intervals, driving the reciprocating screw 24 to rotate. The reciprocating screw 24 is connected to the outer ring plate 27. With the auxiliary guidance and support of the sliding guide rod 25, the outer ring plate 27 can be driven to move up and down reciprocally. The inner side of the outer ring plate 27 is provided with a telescopic groove 28, and a telescopic plate 29 is inserted into the telescopic groove. The telescopic plate 29 can be supported by the spring telescopic rod 30. A brush 31 is fixedly installed on the inner arc surface of the telescopic plate 29. When the outer ring plate 27 moves up and down reciprocally, the dust attached to the nylon pre-filter 19 on the outside of the filter element structure 13 is repeatedly swept away to prevent the dust accumulation from affecting the negative pressure suction effect and thus affecting the dust suction, filtration and collection. The swept-down dust settles into the dust collection drawer 32 in the dust collection chamber 3 at the bottom for collection. The dust collection drawer 32 can be pulled out to clean the collected dust.

[0038] An air inlet groove 5 is provided between the front and back sides of the detachable ventilation plate 4, and a guide splash guard 6 is provided inside the air inlet groove 5.

[0039] When using this device, the suction fan 21 is controlled by the operation panel 34 to draw air from the surrounding area of ​​the device into the dust filter chamber 1 through the air inlet slot 5.

[0040] The filter element fixing and releasing mechanism includes a telescopic rod 8 fixedly mounted on the top of the cross frame 7 and a screw 9 rotatably mounted on the top of the cross frame 7. The screw 9 is threadedly connected to the internal thread transmission sleeve 10. A knob 11 is sleeved on the outside of the screw 9. The tops of the telescopic rod 8 and the internal thread transmission sleeve 10 are fixedly connected to the filter element support frame 12. The top of the filter element support frame 12 is inserted into the filter element structure 13.

[0041] Rotating the knob 11 rotates the screw 9, which, through the transmission between the screw 9 and the internal thread transmission sleeve 10, and under the guidance of the telescopic rod 8, drives the filter element support bracket 12 to rise and fall, thus allowing the filter element structure 13 to be disassembled and assembled.

[0042] The filter element structure 13 includes a top frame 14 and a bottom frame 15. A stainless steel mesh support layer 16, an activated carbon filter layer 17, a HEPA filter 18, and a nylon pre-filter 19 are provided between the top frame 14 and the bottom frame 15. The stainless steel mesh support layer 16, the activated carbon filter layer 17, the HEPA filter 18, and the nylon pre-filter 19 are distributed from the inside to the outside.

[0043] The filter element structure includes a stainless steel mesh support layer 16, an activated carbon filter layer 17, a HEPA filter 18, and a nylon pre-filter 19, distributed sequentially from the inside out. The stainless steel mesh support layer 16 is used to bear pressure and support the entire filter element. Dust first comes into contact with the nylon pre-filter 19, which is used to initially block larger dust particles. Fine particles that pass through the nylon pre-filter 19 are effectively blocked by the HEPA filter 18 and the activated carbon filter layer 17. The airflow after effective filtration is discharged from the top of the air duct 2.

[0044] The top of the air duct 2 is threadedly connected to a top barrier net 22.

[0045] The top barrier net 22 prevents foreign objects from falling into the top air duct of the device.

[0046] The two ends of the outer ring plate 27 are respectively threaded to the reciprocating lead screw 24 and slidably connected to the sliding guide rod 25.

[0047] The reciprocating screw 24 is driven to rotate by the motor 23. The reciprocating screw 24 is connected to the outer ring plate 27. With the auxiliary guidance and support of the sliding guide rod 25, the outer ring plate 27 can be driven to move up and down reciprocally.

[0048] The bottom of the dust collection chamber 3 is connected to casters 33.

[0049] The omnidirectional wheels 33 allow this device to be moved easily and quickly deployed in different locations as needed.

[0050] The side of the air duct 2 is provided with an operation panel 34.

[0051] The operation panel 34 is equipped with a touch screen and a power switch. The operation panel 34 has a processing unit inside for controlling the device.

[0052] The working principle and usage process of this utility model are as follows: When using this device, the suction fan 21 is controlled by the operation panel 34. The air around the device is drawn into the dust filter chamber 1 through the air inlet slot 5. The dust generated during mining operations enters the dust filter chamber 1 under the guidance of negative pressure suction. A guide splash plate 6 is set on the inner side of the air inlet slot to guide the flow and prevent larger particles or water mist from splashing in. The dust airflow introduced from multiple sides is filtered through the filter element structure 13. The filter element structure includes a stainless steel mesh support layer 16 and activated carbon distributed from the inside to the outside. The filter layer 17, HEPA filter 18, and nylon pre-filter 19, along with the stainless steel mesh support layer 16, are used to bear pressure and support the entire filter element. Dust first comes into contact with the nylon pre-filter 19, which provides initial blocking for larger dust particles. Fine particles that pass through the nylon pre-filter 19 are effectively blocked by the HEPA filter 18 and activated carbon filter layer 17. The effectively filtered airflow is discharged from the top of the air duct 2. The top barrier net 22 prevents foreign objects from falling into the top air duct of this device.When this device is running, the motor 23 can be turned on at regular intervals, driving the reciprocating screw 24 to rotate. The reciprocating screw 24 is connected to the outer ring plate 27. With the auxiliary guidance and support of the sliding guide rod 25, the outer ring plate 27 can be driven to move up and down reciprocally. The inner side of the outer ring plate 27 is provided with a telescopic groove 28, and a telescopic plate 29 is inserted into the telescopic groove. The telescopic plate 29 can be supported by the spring telescopic rod 30. A brush 31 is fixedly installed on the inner arc surface of the telescopic plate 29. When the outer ring plate 27 moves up and down reciprocally, it brushes the nylon pre-coated material on the outside of the filter element structure 13. The dust on the filter screen 19 is repeatedly swept to prevent dust accumulation from affecting the negative pressure suction effect and thus affecting dust intake, filtration, and collection. The swept dust settles into the dust collection drawer 32 in the bottom dust collection chamber 3 for collection. The dust collection drawer 32 can be pulled out to clean the collected dust. The upper and lower ends of the filter element structure 13 are fixed by the top frame 14 inserted into the top positioning plate 20 and the bottom frame 15 inserted into the filter element support bracket 12, respectively. When the filter element needs to be replaced, the detachable ventilation plate 4 can be removed, and the screw 9 can be rotated by the knob 11 to ventilate. Through the transmission between the screw 9 and the internal threaded transmission sleeve 10, and guided by the telescopic rod 8, the filter element support 12 is driven to descend, thereby driving the filter element structure 13 to descend. This causes the top frame 14 to leave the top positioning plate 20, and the filter element structure 13 can be manually pulled down to press the telescopic plate 29 into the telescopic groove 28. This prevents the brush 31 and the telescopic plate 29 from obstructing the removal of the filter element structure 13. The filter element structure 13 can then be removed from the dust filter chamber 1 to replace it with a new filter element structure 13. After the top frame 14 passes through the inner ring plate 27, the knob is turned in the opposite direction. Step 11 will cause the filter element support frame 12 to rise, pushing the filter element structure 13 upwards, so that the top frame 14 and bottom frame 15 can be inserted and fixed between the top positioning plate 20 and the filter element support frame 12, thus completing the installation of the filter element structure 13. In summary, this device has a compact structure and a convenient filter element replacement structure. At the same time, it can automatically clean the dust attached to the outside of the filter element in a timely manner to avoid clogging the filtration passage. It is suitable for the continuous dust removal needs in heavy dust and high pollution working environments such as metallurgy and mining, and can effectively improve the cleanliness of the working environment and protect the health of personnel and the safety of equipment operation.
