[0028] An integrated device for dust collection and reuse from a hammer crusher, such as Figure 1-7 As shown, the system includes: a dust collection mechanism, a dust collection box 11, two electrostatic dust removal plates 12, two lifting mechanisms, and a dust removal assembly; the dust collection mechanism includes a first dust collection assembly and a second dust collection assembly, which are respectively located at the feed inlet and discharge outlet of the hammer crusher 10; the dust collection box 11 is located on one side of the hammer crusher 10, and a material collection trough is provided at the bottom of the dust collection box 11, with the output ends of both the first and second dust collection assemblies connected to the dust collection box 11; the two electrostatic dust removal plates 12 are staggered inside the dust collection box 11; the two lifting mechanisms are respectively...

The output end of the air blowing assembly is connected to the connecting seats 13. The connecting seats 13 are provided with at least two air jets 15. The two scrapers 14 are respectively provided on the two connecting seats 13 and are respectively attached to the two sides of the electrostatic dust removal plate 12. The air jets 15 and the scrapers 14 are opposite to each other.

[0029] By adopting the above structure, and by setting a first dust collection component and a second dust collection component at the feed inlet and discharge outlet of the hammer crusher 10 respectively, it is ensured that the dust generated during the material crushing process can be collected in a timely and effective manner, thereby improving the dust removal effect. By staggering the two electrostatic dust removal plates 12, the dust is adsorbed on the electrostatic dust removal plates 12. The gas after dust removal is discharged through the exhaust port 33. The lifting mechanism drives the scraper 14 to move up and down, thereby automatically scraping off the dust adsorbed on the electrostatic dust removal plates 12. Pressurized gas is sprayed out by the jet nozzle 15, thereby blowing off the dust remaining on the scraper 14 and causing it to fall into the feed chute 29, thus achieving centralized dust recovery for the purpose of dust reuse.

[0030] Specifically, two electrostatic dust collectors are inclined and staggered inside the dust collection box 11, thereby guiding the airflow carrying dust and increasing the contact between the airflow and the electrostatic dust collector plate 12, thus improving the dust removal effect. The airflow after dust removal is discharged through the exhaust port 33.

[0032] The operation of the first dust pump 17 causes the first dust hood 18 to suck the dust at the feed inlet into the dust collection box 11, and the first support frame 16 supports the position of the first dust pump 17 and the first dust hood 18.

[0033] In embodiments of this utility model, such as Figure 1-7 As shown, the second dust collection assembly includes: a second support frame 19, a second dust collection pump 20, and a second dust collection hood 21; the second support frame 19 is disposed at the discharge port of the hammer crusher 10; the second dust collection pump 20 is fixed on the second support frame 19, and the output end of the second dust collection pump 20 is connected to the dust collection box 11; the second dust collection hood 21 is connected to the input end of the second dust collection pump 20, and the second dust collection hood 21 is positioned opposite to the discharge port of the hammer crusher 10.

[0034] The operation of the second dust pump 20 causes the second dust hood 21 to suck the dust at the discharge port into the dust collection box 11, and the second support frame 19 supports the position of the second dust pump 20 and the second dust hood 21.

[0035] In embodiments of this utility model, such as Figure 1-5 As shown, the lifting mechanism includes: a bracket 22, a hydraulic cylinder 23, a lifting seat 24, and four connecting rods 25; the bracket 22 is fixed to the top of the dust collection box 11; the hydraulic cylinder 23 is fixed on the bracket 22; the lifting seat 24 is connected to the telescopic end of the hydraulic cylinder 23; the four connecting rods 25 are respectively set at the bottom of the lifting seat 24, and the four connecting rods 25 are respectively connected to two connecting seats 13.

The hydraulic cylinder 23 extends and retracts, which drives the lifting seat 24 and the connecting rod 25 to move up and down, thereby simultaneously driving the two connecting seats 13 to move up and down, so that the scraper 14 scrapes off the dust on the surface of the electrostatic dust removal plate 12.

[0037] In embodiments of this utility model, such as Figure 1-5 As shown, the air blowing assembly includes: an air tank 26 and a three-way connecting pipe 27; the air tank 26 is fixed on the lifting base 24; the three-way connecting pipe 27 has one inlet and two outlets, the inlet of the three-way connecting pipe 27 is connected to the air tank 26, and the two outlets are respectively connected to two connecting bases 13.

[0042] By setting a first filter screen 31 and a second filter screen 32 on the first dust suction hood 18 and the second dust suction hood 21 respectively, the dust sucked out can be filtered to prevent larger particles from being sucked into the dust suction hood during the crushing process and causing equipment blockage.

[0043] Implementation Process: Using the above structure, a first dust collection component and a second dust collection component are respectively installed at the feed inlet and discharge outlet of the hammer crusher 10 to ensure that the dust generated during the material crushing process can be collected in a timely and effective manner, thereby improving the dust removal effect. By staggering the two electrostatic precipitator plates 12, dust is adsorbed onto the plates. The gas after dust removal is discharged through the exhaust port 33. A lifting mechanism drives the scraper plate 14 to move up and down, automatically scraping off the dust adsorbed on the electrostatic precipitator plates 12. Pressurized gas is then ejected through the jet nozzle 15, blowing off the dust remaining on the scraper plate 14 and causing it to fall into the feed chute 29, thus achieving centralized dust recovery for secondary utilization.
