DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 The utility model provides an embodiment: a dust removal device, comprising: a sedimentation box 1; a filtering mechanism and a high-pressure water pump 15 are provided on the inner side of the sedimentation box 1, and a dust removal mechanism is provided above the sedimentation box 1. The grinding dust enters the dust removal mechanism, and the high-pressure water pump 15 pressurizes the liquid in the sedimentation box 1 and transports it to the dust removal mechanism for spraying. After dust removal, the liquid flows back to the inner side of the sedimentation box 1 for collection and is filtered through the filtering mechanism.

[0025] In this embodiment, spray liquid is injected into the inner side of the sedimentation box 1, and the spray liquid is pressurized to the inner side of the dust removal mechanism by the high-pressure water pump 15 to spray the incoming grinding dust. The grinding dust after spraying flows back to the inner side of the sedimentation box 1 from the first grinding dust outlet 6 and the second grinding dust outlet 9 with the liquid, and the dust in the liquid is blocked and precipitated by the filtering mechanism for filtering. The filtered liquid can be sprayed and used again, and the grinding dust is sprayed and filtered by the dust removal mechanism. The grinding dust passes through the two processes of the first cylinder 2 and the second cylinder 3 to achieve the effect of secondary purification. The dust removal effect is good, and secondary pollution is avoided. The metal dust in the grinding dust can be effectively cleaned and collected. The overall production cost is low, and the cost is only about 20% of the traditional bag-type vacuum cleaner; it is more energy-saving, saving 50% of electricity than traditional dust removal; it occupies a smaller area, is efficient and saves space.

[0026] The dust removal mechanism includes a first cylinder 2 and a second cylinder 3. A first dust inlet 4 is provided on the lower side of the first cylinder 2, a first upper air outlet 5 is provided on the upper part of the first cylinder 2, and a first dust outlet 6 is provided on the lower surface of the first cylinder 2. The first dust outlet 6 extends to the inside of the sedimentation box 1 and is located below the liquid level; a second dust inlet 7 is provided on the lower side of the second cylinder 3, and the second dust inlet 7 is connected to the first upper air outlet 5. A second upper air outlet 8 is provided on the top of the second cylinder 3, and a second dust outlet 9 is provided on the bottom of the second cylinder 3. The second dust outlet 9 is located above the liquid level; a first spray head 10 is fixedly provided on the inside of the first cylinder 2, and a second spray head 11 is fixedly provided on the inside of the second cylinder 3. The high-pressure water pump 15 is connected to the first spray head 10 and the second spray head 11 through a pipeline.

[0027] In this embodiment, the first cylinder 2 is connected to the second cylinder 3. After the grinding dust enters from the first grinding dust inlet 4, it undergoes the first spraying treatment. The sprayed liquid carries the adsorbed metal dust back to the sedimentation box 1 from the first grinding dust outlet 6, and the gas enters the second cylinder 3 from the first upper air outlet 5 for secondary cleaning. The first grinding dust outlet 6 extends to the inside of the sedimentation box 1 and is located below the liquid level to prevent dust generation.

[0028] The grinding dust after the first spraying enters the inner side of the second cylinder 3 through the second grinding dust inlet 7, and is sprayed for the second time on the grinding dust with smaller particles. The second grinding dust outlet 9 below the second cylinder 3 is located above the liquid level of the sedimentation box 1, which increases the contact time between the grinding dust and the spraying water vapor and enhances the purification efficiency. The gas after the second spraying is discharged from the second upper air outlet 8, and the spraying liquid flows back to the inner side of the sedimentation box 1. The liquid in the sedimentation box 1 is transported to the first spray head 10 and the second spray head 11 by the high-pressure water pump 15 for dust removal. The water mist sprayed by the spray head is combined with the grinding dust particles to increase their own gravity to achieve the effect of sedimentation, collection and dust removal, avoiding the problem of spontaneous combustion and explosion, and improving safety.

[0029] The first spray head 10 is located between the first grinding dust inlet 4 and the first upper air outlet 5, and the second spray head 11 is located between the second grinding dust inlet 7 and the second upper air outlet 8. It sprays the grinding dust gas coming out of the first grinding dust inlet 4 and the second grinding dust inlet 7, so that the gas moves upward, and the metal dust adsorbed by the spray refluxes the spray liquid to remove dust.

[0030] The cross-sections of the first grinding dust inlet 4 and the second grinding dust inlet 7 are inverted trapezoidal structures.

[0031] In this embodiment, the cross-sectional shape is set to an inverted trapezoid, which effectively solves the problem of spray liquid backflow and prevents the spray liquid from entering the inner side of the first grinding dust inlet 4 and the second grinding dust inlet 7, causing metal dust to be adsorbed and accumulated at the first grinding dust inlet 4 and the second grinding dust inlet 7.

[0032] An automatic liquid level controller 16 is provided in the sedimentation box 1 , and the automatic liquid level controller 16 is electrically connected to the high-pressure water pump 15 .

[0033] In this embodiment, the liquid level automatic controller 16 plays a role in water level warning, thereby avoiding the problem of reduced dust removal effect caused by the water level being too high or too low.

[0034] The filtering mechanism includes a first dust shield 12 and a second dust shield 13. The first dust shield 12 is located between the first cylinder 2 and the second cylinder 3, and the second dust shield 13 is located on one side of the first dust shield 12. A partition 14 is provided on the inner side of the sedimentation box 1, and the partition 14 divides the sedimentation box 1 into two connected volume cavities. The partition 14 is located between the second cylinder 3 and the high-pressure water pump 15.

[0035] In this embodiment, the height of the first dust shield 12 is higher than that of the second dust shield 13, and the abrasive particles are collected in layers to facilitate the reflux and reuse of the spray liquid; the dust shield separates the grinding dust collection area from the high-pressure water pump 15, which facilitates the cleaning of the grinding dust particles and is more environmentally friendly.

[0036] Working principle: One end of the axial flow fan is connected to the needle grinding machine dust collection hood, and the other end is connected to the first grinding dust inlet 4. After the grinding dust enters the first cylinder 2, it repeatedly combines with the mist water vapor produced by the high-pressure spray head in the first cylinder 2, and sinks into the sedimentation box 1 under the action of gravity. There are a first dust shield 12 and a second dust shield 13 in the sedimentation box 1, which divide the metal dust into different areas. The air that has purified the grinding dust flows from the first upper air outlet 5 above the first cylinder 2 to the second grinding dust inlet 7 below the second cylinder 3. Because the dust particles are small, the second grinding dust outlet 9 below the second cylinder 3 is not connected to the liquid surface, which increases the contact time between the grinding dust and the spraying water vapor, enhances the purification efficiency, and finally completes the sedimentation of the metal dust.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
