[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] The utility model provides a grinding machine for producing activated carbon, which is applied in the production process of activated carbon by phosphoric acid method.

[0021] Please refer to Figure 1 to Figure 2 As shown, the grinding machine for activated carbon production of the utility model comprises:

[0022] The cylinder 1 is hollow inside and is provided with a feed port 11, a support plate 12 and a discharge port 13 from top to bottom;

[0023] The extrusion and grinding roller group 2 is rotatably arranged in the cylinder 1 and is located between the feed port 11 and the support plate 12;

[0024] The grinding roller set 3 is rollingly arranged on a support plate 12 , and a mesh 121 is arranged on the support plate 12 .

[0025] From the above description, it can be seen that the beneficial effects of the utility model are: providing a grinding mill for activated carbon production, a grinding chamber is provided in the cylinder 1, after the activated carbon is put into the grinding chamber from the feed port 11, it is first extruded and ground by the extrusion and grinding roller group 2, and then the carbon powder falling on the support plate 12 is ground by the grinding roller group 3, and the carbon powder after two grindings falls from the mesh 121 on the support plate 12 to the discharge port 13. The activated carbon production grinding mill provided by the utility model solves the problem of large differences in the particle size of the ground carbon powder through a two-stage grinding process, which is beneficial to the screening and classification of the carbon powder according to the diameter after grinding and the improvement of the quality of the carbon powder.

[0026] In an optional embodiment, the grinding roller set 2 includes a grinding roller body 21, two grinding roller bodies 21 are vertically arranged in the cylinder 1, and the two grinding roller bodies 21 have the same rotation direction.

[0027] As can be seen from the above description, by turning to the same two extrusion roller bodies 21, the activated carbon falling between the two is extruded and ground, thereby preliminarily reducing the particle size of the carbon powder.

[0028] In an optional embodiment, the grinding roller group 3 includes a rotating shaft 31 and a grinding roller body 32 , wherein the rotating shaft 31 is vertically arranged in the cylinder 1 , the grinding roller body 32 is rotatably connected to the rotating shaft 31 , and the grinding roller body 32 is horizontally rollingly arranged on the support plate 12 .

[0029] From the above description, it can be known that the grinding roller body 32 rolls along the circumferential direction on the support plate 12 under the rotation of the rotating shaft 31, grinding the carbon powder on the support plate 12 during rolling to further reduce the particle size of the carbon powder.

[0030] In an optional embodiment, a motor 4 is further included, and the rotating shaft 31 and the two grinding roller bodies 21 are respectively connected to the corresponding motor 4.

[0031] From the above description, it can be known that the motor 4 is used to drive the rotating shaft 31 and the grinding roller to rotate, so as to control the grinding quality of the carbon powder.

[0032] In an optional embodiment, the grinding roller set 3 further includes a scraper 33, which is horizontally arranged on the rotating shaft 31, and a notch 331 for carbon powder to pass through is provided at a distance at a lower edge of the scraper 33.

[0033] From the above description, it can be seen that the scraper 33, driven by the rotation of the shaft 31, gradually scrapes the ground carbon powder into the mesh 121 to avoid clogging of the mesh 121. The setting of the notch 331 avoids the accumulation of carbon powder and improves the uniformity of carbon powder grinding.

[0034] In an optional embodiment, the scraper 33 is arranged along the chord direction of the rotating shaft 31 .

[0035] From the above description, it can be known that the scraper 33 is arranged to have an angle with the diameter direction of the rotating shaft 31 , and the scraper 33 can gradually scrape the carbon powder toward the middle or edge of the support plate 12 when the rotating shaft 31 rotates.

[0036] In an optional embodiment, a material receiving box 14 is provided at the material outlet 13, and the material receiving box 14 is provided with two or more material receiving bins from the middle to the edge.

[0037] From the above description, it can be seen that when the scraper 33 makes a circular motion, it slowly scrapes the carbon powder into the mesh 121, so that the carbon powder obtained by different grinding levels falls into different receiving bins respectively. The carbon powder that falls first has a large mesh number, and the carbon powder that falls later has a small mesh number and high precision, which makes it convenient to screen and classify the carbon powder according to its particle size.

[0038] The working principle of the utility model is: when in use, after the activated carbon is put into the grinding chamber from the feed port 11, the motor 4 is turned on to grind the carbon powder, firstly, the extrusion and grinding roller group 2 is used for extrusion and grinding, and then the carbon powder falling on the support plate 12 is ground by the grinding roller group 3. After two passes of grinding, the carbon powder falls from the mesh 121 on the support plate 12 to the receiving bin corresponding to the receiving box 14 under the action of the scraper 33.

[0039] Please refer to Figure 1 to Figure 2 As shown, the first embodiment of the utility model is: a grinding machine for producing activated carbon, comprising:

[0040] The cylinder 1 is hollow inside and is provided with a feed port 11, a support plate 12 and a discharge port 13 from top to bottom;

[0042] The grinding roller set 3 is rollingly arranged on a support plate 12 , and a mesh 121 is arranged on the support plate 12 .

[0043] The extrusion roller group 2 includes an extrusion roller body 21, two of which are vertically arranged in the cylinder 1, and the two extrusion roller bodies 21 have the same direction of rotation. The grinding roller group 3 includes a rotating shaft 31 and a grinding roller body 32, the rotating shaft 31 is vertically arranged in the cylinder 1, the grinding roller body 32 is rotatably connected to the rotating shaft 31, and the grinding roller body 32 is horizontally rolled on the support plate 12. It also includes a motor 4, and the rotating shaft 31 and the two extrusion roller bodies 21 are respectively connected to the corresponding motors 4. The grinding roller group 3 also includes a scraper 33, the scraper 33 is horizontally arranged on the rotating shaft 31, and the lower edge of the scraper 33 is spaced apart with a notch 331 for carbon powder to pass through. The scraper 33 is arranged along the chord direction of the rotating shaft 31. A material receiving box 14 is provided at the discharge port 13, and the material receiving box 14 is provided with more than two material receiving bins from the middle to the edge.
