Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for mining equipment, specifically to a dust removal structure for a mining screening machine. Background Technology

[0002] Screening machines are commonly used material grading equipment in mining production. However, screening machines generate a large amount of dust during operation. This dust not only pollutes the working environment and endangers the health of operators, but also affects the normal operation and maintenance of the equipment.

[0003] Traditionally, dust removal vehicles are often used next to the screening machine to spray water mist for dust control. However, this method has certain limitations. The spraying range of the dust removal vehicle is limited, making it difficult to fully cover the dust-generating area produced by the screening machine, resulting in some dust leakage and affecting the working environment and the health of operators.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] In order to provide comprehensive coverage of the screening machine, combined with the attached Figure 2 and attached Figure 4 A dust removal structure for a mining screening machine includes a housing 1, which is arranged at an angle. One side of the housing 1 has a first opening 2, and the other side has a second opening 3. The structure also includes support legs 5. Four support legs are respectively located below the housing 1, and the height of the housing 1 can be adjusted by a height adjustment assembly on the support legs 5. The height adjustment assembly includes extension rods 4 and limiting holes 7. The four extension rods 4 are respectively inserted into the support legs 5, and the top ends of the extension rods 4 are fixedly connected to the top of the housing 1. Several limiting holes 7 are evenly distributed on the extension rods 4. The height adjustment assembly also includes locking bolts 6 and double nuts 8. The locking bolts 6 pass through the support legs 5 and the limiting holes 7 in sequence, and the double nuts 8 are threaded onto the locking bolts 6, locking the extension rods 4 and support legs 5 together. The bottom end of each support leg 5 is provided with a self-locking caster wheel 9. Remove the locking bolt 6 and double nuts 8 respectively, lift the box 1 upwards so that the extension rod 4 extends outwards continuously. When the box 1 reaches the appropriate position, pass the locking bolt 6 through the support leg 5 and the limiting hole 7 in sequence. The double nuts 8 are threaded onto the locking bolt 6, which can lock the extension rod 4 and the support leg 5 together. With the assistance of the self-locking caster 9, push it directly to the top of the screening machine.

[0026] In order to reduce dust, combined with the attached... Figure 1 and attached Figure 3The dust removal structure is located at the top of the housing 1, allowing direct spraying of dust through the first opening 2 and the second opening 3 of the housing 1. A protective cover 10 is provided at the bottom of the housing 1. The dust removal structure includes a water tank 11, a pump 12, and spray pipes 13. Both the water tank 11 and the pump 12 are located at the top of the housing 1, with the input end of the pump 12 connected to the water tank 11. Pairs of spray pipes 13 are fixed above the first opening 2 and the second opening 3, and each spray pipe 13 is connected to the output end of the pump 12. The dust removal structure also includes atomizing nozzles 14. Several atomizing nozzles 14 are evenly distributed on the spray pipes 13, directly spraying dust through the first opening 2 and the second opening 3. The top of the water tank 11 has a water inlet, and the spray pipes 13 are directly fixed to both sides of the housing 1 using pipe clamps. Since the overall structure is located above the screening machine, and with the protective cover 10 at the bottom of the box 1, the all-round covering dust removal method is adopted, which effectively prevents the leakage of dust during the operation of the screening machine. The dust will continuously drift to the first opening 2 and the second opening 3. At this time, the liquid pump 12 is started. The liquid pump 12 directly draws water from the water tank 11 and sends it to multiple atomizing nozzles 14 on the water spray pipe 13 to directly suppress the dust that is continuously discharged.

[0027] In specific implementation of this utility model:

[0028] First, remove the locking bolts 6 and double nuts 8 one by one, lift the box 1 upwards so that the extension rod 4 extends outwards continuously. When the box 1 reaches the appropriate position, pass the locking bolts 6 through the support leg 5 and the limiting hole 7 in sequence. The double nuts 8 are threaded onto the locking bolts 6, which can lock the extension rod 4 and the support leg 5 together. With the assistance of the self-locking caster 9, push it directly to the top of the screening machine.

[0029] At this time, the entire structure is located above the screening machine. With the protective cover 10 at the bottom of the box 1, the all-round dust removal method is adopted to effectively prevent the leakage of dust during the operation of the screening machine. The dust will continuously drift to the first opening 2 and the second opening 3. At this time, the liquid pump 12 is started. The liquid pump 12 directly draws water from the water tank 11 and sends it to multiple atomizing nozzles 14 on the water spray pipe 13 to directly suppress the dust that is continuously discharged.
