Description

Technical Field

[0001] The utility model relates to a Raymond grinder, in particular to a metal powder grinding system. Background Art

[0002] When preparing metal powders such as iron-nickel alloy powders, Raymond mills are generally used for grinding. The existing Raymond mills include a main machine for grinding metal powders, which is connected to a powder collector. The ground powder in the main machine is transported to the powder collector by wind, and the metal powder is collected from the powder outlet of the powder collector. The dust flows out from the air outlet of the powder collector under the action of wind, and the outflowing flue gas dust is generally directly removed by a bag dust collector. This grinding system is not thorough enough for preparing metal powders, and there is still a lot of dust in the workshop, and the working environment is poor. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a metal powder grinding system with more thorough dust removal.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a metal powder grinding system, including a main machine of a Raymond mill for grinding metal powder, the main machine is connected to a powder collector, the powder ground in the main machine is transported to the powder collector through a material pipe under the action of wind force, the metal powder is collected from the powder outlet of the powder collector, the air outlet of the powder collector is connected to a spray tower through a dust pipe, the dust flowing out of the air outlet is dedusted by the spray tower and then transported to a bag dust collector for further dedusting.

[0005] Preferably, a cyclone fan is provided on the material pipe.

[0006] Preferably, the spray tower includes a closed tower body, a water tank arranged at the top of the tower body and a water collecting tank arranged at the bottom of the tower body; a plurality of spray pipes are arranged at the upper part of the tower body, and the water in the water tank is sprayed downward through the spray pipes; the dust pipe is connected to the lower part of one side of the tower body, and an air outlet pipe is arranged at the top of the tower body, which is connected to the bag-type dust collector; the dust flowing into the tower body from the dust pipe is dust-removed by the water sprayed from the spray pipe and then flows into the bag-type dust collector from the air outlet pipe, and the water collecting tank collects the water after dust removal.

[0007] Preferably, both ends of each spray pipe are provided with nozzles for spraying water toward the inner wall of the tower body.

[0008] Preferably, the tower body is in a cone shape with a small upper end and a large lower end.

[0009] From the above technical scheme, it can be seen that the utility model performs double dust removal on the flue gas dust generated by the preparation of metal powder through the spray tower and the bag dust collector, and the dust removal is more thorough; and the closed design of the spray tower not only ensures the dust removal effect, prevents the dust from spreading in the workshop, and improves the working environment; and the centralized recovery of spray water by the spray tower reduces environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] Combine the following Figure 1 The present invention is described in detail. The exemplary embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0012] like Figure 1 The utility model provides a metal powder grinding system, which includes a main machine 1 of a Raymond mill for grinding metal powder, the main machine is connected to a powder collector 2, the powder ground in the main machine is transported to the powder collector through a material pipe 3 under the action of wind, and metal powder is collected from the powder outlet of the powder collector, the air outlet of the powder collector is connected to a spray tower 5 through a dust pipe 4, and the dust flowing out of the air outlet is dust-removed by the spray tower and then transported to a bag dust collector 6 for dust removal again, thereby achieving double dust removal, ensuring more thorough dust removal, and greatly improving the dust removal effect. During the implementation process, a cyclone fan 7 is provided on the material pipe, which causes the powder to generate a cyclone, so that the powder is better separated in the powder collector, and the quality of the collected metal powder is improved.

[0013] Specifically, the spray tower 5 includes a closed tower body 51, a water tank 52 arranged at the top of the tower body, and a water collection tank 53 arranged at the bottom of the tower body; the tower body of the utility model adopts a closed structure, which can prevent dust leakage and improve the dust removal effect; a plurality of spray pipes 54 are arranged at the upper part of the tower body, and the water in the water tank is sprayed downward through the spray pipes, so that water mist is formed in the tower body; the dust pipe is connected to the lower part of one side of the tower body, and an air outlet pipe 8 is arranged at the top of the tower body, which is connected to the bag filter. The dust flowing into the tower body from the dust pipe is dusted by the water mist formed by the water sprayed by the spray pipe, and then flows from the air outlet pipe into the bag filter for dust removal again, thereby realizing double dust removal; and the dust removed water is collected by the water collection tank at the bottom for centralized treatment. If the water collected in the water collection tank is filtered, the clean water is transported to the water tank for reuse, and the filtered residue can be used as raw material.

[0014] During the implementation process, the water sprayed downward from the spray pipe on the upper part of the tower body collides with the dust at the lower part, thereby knocking the heavier solid dust into the collection tank, while the lighter gas flows out from the air outlet from the bottom to the top, realizing wet dust removal. Preferably, both ends of each spray pipe are provided with a nozzle 55 for spraying water to the inner wall of the tower body, so that a water curtain is formed on the inner wall of the tower body, thereby removing the dust in contact with the inner wall of the tower body, further improving the dust removal effect. The tower body of the utility model is in a cone shape with a small upper end and a large lower end, thereby ensuring that the rising dust is fully in contact with the water mist in the tower body, greatly improving the dust removal effect.
