Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a dust-free multi-stage pulverizing device. Background Art

[0002] Roller crusher is one of the oldest crushing equipment. It has a simple structure and is still used in cement, silicate and other industrial sectors. It is mainly used for medium and fine crushing of ore. The crushing rollers inside most roller crushers are basically exposed to the air. When the crushing rollers are working, a large amount of dust will be generated, affecting the air environment.

[0003] The crushing mode of most crushers is relatively single, which cannot guarantee a good crushing effect, and cannot screen the crushed materials, and cannot accurately distinguish the unqualified materials, resulting in the inconvenience of using the crushing device.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The dust-free multi-stage crushing device allows the crushed material to enter the crushing box through the feed pipe. After the crushing roller crushes the material, it falls on the inclined plate. The qualified crushed material will fall into the collection box through the filter screen, while the unqualified crushed material is driven by the motor to drive the scraper to enter the screening box along the inclination angle of the inclined plate for secondary crushing.

[0015] 2. In this dust-free multi-stage crushing device, the hydraulic rod drives the crushing plate to descend. After the crushing plate contacts the filter plate, the material is squeezed to perform secondary crushing on the material. When the crushing roller rotates, the micro vacuum cleaner is turned on to prevent the dust generated by the crushing from being discharged through the feed pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A dust-free multi-stage crushing device in this embodiment includes a crushing box 1, a screening structure 2 is arranged inside the crushing box 1, and a crushing structure 3 is arranged outside the crushing box 1.

[0022] The screening structure 2 includes a feed pipe 201, a rotating rod 202, a crushing roller 203, a gear 204, a first motor 205, an inclined plate 206, a filter screen 207, a second motor 208 and a scraper 209. The feed pipe 201 is fixedly installed on the top of the crushing box 1, the rotating rod 202 is movably installed inside the crushing box 1, the crushing roller 203 is fixedly installed outside the rotating rod 202, the gear 204 is fixedly installed outside the rotating rod 202, the first motor 205 is fixedly installed outside the crushing box 1, the inclined plate 206 is fixedly installed inside the crushing box 1, the filter screen 207 is fixedly installed inside the inclined plate 206, the second motor 208 is fixedly installed on the bottom of the inclined plate 206, and the scraper 209 is fixedly installed on the output shaft of the second motor 208.

[0023] The crushing structure 3 includes a screening box 301, a hydraulic rod 302, a crushing plate 303, a filter plate 304, a collecting box 305, a dust collecting pipe 306 and a miniature vacuum cleaner 307. The screening box 301 is fixedly installed on the outside of the crushing box 1, the hydraulic rod 302 is fixedly installed on the inside of the screening box 301, the crushing plate 303 is fixedly installed on the bottom of the hydraulic rod 302, the filter plate 304 is fixedly installed on the inside of the screening box 301, the collecting box 305 is arranged on the bottom of the screening box 301, the dust collecting pipe 306 is fixedly installed on the outside of the crushing box 1, and the miniature vacuum cleaner 307 is fixedly installed on the outside of the dust collecting pipe 306.

[0024] exist Figure 2 There are two dust collecting pipes 306 , which are respectively located on the left and right sides of the feed pipe 201 . The tops of the two dust collecting pipes 306 both penetrate the feed pipe 201 and are fixedly connected to the feed pipe 201 .

[0025] exist Figure 2 In the embodiment, the bottoms of the two dust collecting pipes 306 penetrate through the crushing box 1 and extend to the interior of the crushing box 1 , and the bottoms of the dust collecting pipes 306 are fixedly connected to the crushing box 1 .

[0026] exist Figure 2 In the process, the collecting box 305 enters the crushing box 1 from the taking port and is located at the bottom of the inclined plate 206 to collect the materials after being filtered by the filter screen 207.

[0027] In summary, in the dust-free multi-stage crushing device, the material to be crushed enters the crushing box 1 through the feed pipe 201. After the crushing roller 203 crushes the material, it falls on the inclined plate 206. The qualified material will pass through the filter screen 207 and fall into the collection box 305, while the unqualified material will be driven by the motor 208 to drive the scraper 209 to make the material enter the screening box 301 along the inclination angle of the inclined plate 206 for secondary crushing.

[0028] In addition, in the dust-free multi-stage crushing device, the hydraulic rod 302 drives the crushing plate 303 to descend. After the crushing plate 303 contacts the filter plate 304, the material is squeezed to perform secondary crushing on the material. When the crushing roller 203 rotates, the micro vacuum cleaner 307 is turned on to prevent the dust generated by the crushing from being discharged through the feed pipe 201. This solves the problem that most crushers have a relatively single crushing mode and cannot guarantee a good crushing effect. They are also unable to screen the crushed materials and cannot accurately distinguish the unqualified crushed materials, resulting in the problem that the crushing device is not convenient to use.
