Description

Technical Field

[0001] The utility model relates to the technical field of powder classification, in particular to a diamond powder classification device. Background Art

[0002] Patent No. CN202322643623.8 discloses a diamond powder grading device. This patent allows larger powders and smaller powders to enter the first collection box and the second collection box respectively through the first material chimney and the second material chimney, and the powders are graded and collected. After the ultrafine powder passes through the second filter, it enters the filter box, and then the gas flow range is narrowed by the funnel to concentrate the ultrafine powder. Finally, the ultrafine powder is intercepted by the filter cotton net, and the ultrafine powder falls on the side wall of the funnel for collection. Finally, the filtered gas is discharged through the exhaust pipe.

[0003] However, the applicant found that the inner wall of the filter box was fixedly connected to the funnel, which made it inconvenient to remove the ultrafine powder collected on the side wall of the funnel. Therefore, we proposed a diamond powder classification device. Utility Model Content

[0020] 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.

[0021] As mentioned in the background art, in order to solve the problem in the prior art that it is inconvenient to remove the ultrafine powder collected on the side wall of the funnel, the utility model provides a diamond powder classification device.

[0022] Example 1

[0023] Reference Figures 1 to 3 A diamond powder grading device includes a workbench 1 on which a mixing drum 2, a screw conveyor 3, a blowing box 4 and two collecting boxes 6 of the same structure are arranged. The bottom of the blowing box 4 is externally connected to a high-pressure air pipe;

[0024] The mixing drum 2 is connected to the screw conveyor 3, the screw conveyor 3 is connected to the blowing box 4, the blowing box 4 is connected to the transmission pipe 5, and the transmission pipe 5 is provided with two filters, and the aperture of the left filter is larger than the aperture of the right filter. Both collecting boxes 6 are connected to the transmission pipe 5;

[0025] A filter cartridge 7 is provided on the transmission pipe 5, and an exhaust pipe 8 is provided on the top of the filter cartridge 7;

[0026] The bottom of the filter cartridge 7 is fitted with a bottom plate 9, and connecting rods 10 are provided on both sides of the top of the bottom plate 9. A cylinder 11 is provided on the top of the connecting rod 10, and the cylinder 11 is fitted with the inner wall of the filter cartridge 7. A funnel 12 is provided at the bottom of the inner wall of the cylinder 11, so that the bottom connection between the cylinder 11 and the funnel 12 is in a closed state. A discharge pipe 13 is provided on the top of the funnel 12, and a mounting ring 14 is provided on the inner wall of the filter cartridge 7. A filter cotton mesh 15 is provided on the inner wall of the mounting ring 14 and is located above the discharge pipe 13.

[0027] A lifting support assembly is provided at the bottom of the base plate 9 .

[0028] The top of the cylinder 11 is fitted onto the mounting ring 14 , which can position the cylinder 11 and ensure that the ultrafine powder blocked by the filter cotton mesh 15 can fall into the cylinder 11 .

[0029] The lifting support assembly includes a sleeve 16, in which a rod 17 connected to the base plate 9 is inserted. The bottom of the sleeve 16 is connected to the output end of the electric telescopic rod 18. The electric telescopic rod 18 drives the sleeve 16 to rise and fall, so that the rod 17 drives the base plate 9 to rise and fall, so that the funnel 12 can be moved out of the filter cartridge 7.

[0030] Example 2

[0031] Reference Figure 1 A base is provided at the bottom of the electric telescopic rod 18 for fixing the electric telescopic rod 18.

[0032] The rest of the structure is the same as that of Example 1.

[0033] The powder is then transported to the blow box 4 by the high-pressure gas sent out, and the powder is blown upward by the high-pressure gas, and then enters the transmission pipe 5. The powder moves to the right along the transmission pipe 5, and then passes through the left filter screen to intercept the larger powder. The smaller powder passes through the left filter screen, and then passes through the right filter screen to intercept the smaller powder. The larger powder and the smaller powder enter the collecting boxes 6 on both sides respectively, and the powder is graded and collected. After the ultrafine powder passes through the right filter screen, it enters the filter cylinder 7, and then passes through the funnel 12 to narrow the gas flow range and concentrate the ultrafine powder. Finally, the ultrafine powder is intercepted by the filter cotton net 15, and the ultrafine powder falls between the side wall of the funnel 12 and the cylinder 11 for collection, and finally the filtered gas is discharged through the exhaust pipe 8.

[0034] When it is necessary to take out the ultrafine powder between the cylinder 11 and the funnel 12, the sleeve 16 is moved downward by the electric telescopic rod 18. Under the action of gravity, the insertion rod 17 drives the bottom plate 9, the connecting rod 10, the cylinder 11, the funnel 12 and the discharge pipe 13 to move downward and away from the filter cylinder 7. Then, the bottom plate 9 is moved upward to make the insertion rod 17 leave the sleeve 16, thereby facilitating the removal of the ultrafine powder inside.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
