DETAILED DESCRIPTION

[0029] 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.

[0030] like Figures 1 to 5 As shown, the utility model provides a sintering device for powder metallurgy processing, comprising:

[0031] Shell 1 and feed barrel 2;

[0032] The feed barrel 2 is fixedly connected to the upper part of the shell 1, and a discharge port 3 is provided at the lower part of the shell 1;

[0033] The screening mechanism is movably connected to the inside of the housing 1, and includes a screening plate 6, a first round block 10, a vertical plate 11, a second round block 12 and a disc 13;

[0034] A feed port 4 is provided inside the feed barrel 2, a screen plate 6 is movably connected below the feed port 4, a first round block 10 is fixedly connected to the front side of the screen plate 6, a vertical plate 11 is movably connected to the outside of the first round block 10, a second round block 12 is movably connected to the bottom end of the vertical plate 11, and a disc 13 is fixedly connected to the rear side of the second round block 12;

[0035] A crushing mechanism, which is movably connected to the right side of the screening plate 6 and includes a rotating column 18;

[0036] The sintering mechanism is fixedly connected to the inner bottom end of the shell 1.

[0037] The powder raw material to be sintered is put in from the feed port 4 and dropped onto the top of the screening plate 6. The motor 19 is started, and the motor 19 drives the rotating column 18 to rotate. The rotating column 18 drives the rotating shaft 16 to rotate through the track 17. The rotating shaft 16 drives the second round block 12 to make a circular motion through the disc 13, so that the vertical plate 11 drives the first round block 10 to move up and down in a cycle, thereby driving the screening plate 6 to vibrate and screen the powder raw material, so that smaller powder falls through the screening hole 7 and larger agglomerates roll down to the top of the crushing mechanism.

[0038] The crawler 17 drives the rotating shaft 16 to rotate and make the second round block 12 do circular motion, so that the vertical plate 11 drives the first round block 10 to move up and down in a cycle, thereby driving the screening plate 6 to vibrate and screen the powder raw material. Compared with the traditional sintering device for powder metallurgy processing, this sintering device for powder metallurgy processing uses the first round block 10 to move up and down in a cycle, so that smaller powder falls through the screening hole 7 and larger agglomerates roll down to the top of the crushing mechanism, thereby improving work efficiency.

[0039] The crushing mechanism further includes a rotating rod 20 and a breaking rod 21;

[0040] The rotating column 18 is movably connected to the rear side of the housing 1 , the rotating rod 20 is fixedly connected to the front side of the rotating column 18 , and the breaking rod 21 is fixedly connected to the outer side of the rotating rod 20 .

[0041] When larger lumps fall above the crushing mechanism through the screening mechanism, the motor 19 drives the rotating column 18 to rotate, and the rotating column 18 drives the rotating rod 20 to rotate, so that the breaking rod 21 continuously rotates to break up the agglomerated powder, so that the agglomerated powder becomes smaller particles, which fall above the iron plate 22 and are heated by the combustion tube 26.

[0042] The motor 19 drives the rotating column 18 to rotate, and the rotating column 18 drives the rotating rod 20 to rotate so that the breaking rod 21 rotates continuously to break up the lumps. Compared with the traditional sintering device for powder metallurgy processing, this sintering device for powder metallurgy processing breaks up the agglomerated powder through the breaking rod 21, increases the contact area between the powder and the iron plate 22, and can better heat the powder.

[0043] The device further includes: a driving mechanism, which is fixedly connected to the rear side of the housing 1 and includes a rotating shaft 16, a crawler 17 and a motor 19;

[0044] The motor 19 is fixedly connected to the rear side of the rotating column 18 , the rotating shaft 16 is fixedly connected to the rear side of the disc 13 , and the crawler belt 17 is movably connected to the outer sides of the rotating shaft 16 and the rotating column 18 .

[0045] The motor 19 is started, and the motor 19 drives the rotating column 18 to rotate. The rotating column 18 drives the rotating shaft 16 to rotate through the crawler 17, thereby completing the operation of the device.

[0046] The sintering mechanism includes an iron plate 22, a burner 24, a combustion tube 25 and a combustion pipe 26;

[0047] The iron plate 22 is fixedly connected to the inner bottom end of the outer shell 1, and a filter hole 23 is opened at the bottom of the iron plate 22. The burner 24 is located at both ends of the iron plate 22 and is fixedly connected to the bottom of the outer shell 1. The combustion tube 25 is fixedly connected above the burner 24, and the combustion tube 26 is fixedly connected above the combustion tube 25.

[0048] The burner 24 sprays flames from the combustion tube 26 through the combustion tube 25 to heat both sides of the iron plate 22 , so that the powder above the iron plate 22 melts and flows out from the filter hole 23 .

[0049] A first fixed round block 14 is fixedly mounted on the outer side of the first round block 10 , and a second fixed round block 15 is fixedly mounted on the outer side of the second round block 12 .

[0050] The first round block 10 is fixed by the first fixing round block 14 , and the second round block 12 is fixed by the second fixing round block 15 , so as to prevent the vertical plate 11 from being separated from the first round block 10 and the second round block 12 .

[0051] Among them, a connecting shaft 8 is fixedly installed on the rear side of the screening plate 6, and a limiting block 9 is fixedly installed on the rear side of the connecting shaft 8.

[0052] The up and down shaking of the screening plate 6 drives the connecting shaft 8 to shake up and down, thereby driving the limit block 9 to shake up and down to limit the screening plate 6.

[0053] A limiting groove 5 is provided inside the housing 1 , and a limiting block 9 is movably installed inside the limiting groove 5 .

[0054] Raising the limiting groove 5 to limit the limiting block 9 can prevent the screening plate 6 from deviating from the screening area during the up and down shaking process.

[0055] The working principle and use process of this utility model:

[0056] The powder raw material to be sintered is put in from the feed port 4 and dropped onto the top of the screening plate 6. The motor 19 is started, and the motor 19 drives the rotating column 18 to rotate. The rotating column 18 drives the rotating shaft 16 to rotate through the track 17. The rotating shaft 16 drives the second round block 12 to make a circular motion through the disc 13, so that the vertical plate 11 drives the first round block 10 to move up and down in a cycle, thereby driving the screening plate 6 to vibrate and screen the powder raw material, so that smaller powder falls through the screening hole 7 and larger agglomerates roll down to the top of the crushing mechanism.

[0057] When larger lumps fall above the crushing mechanism through the screening mechanism, the motor 19 drives the rotating column 18 to rotate, and the rotating column 18 drives the rotating rod 20 to rotate, so that the breaking rod 21 continuously rotates to break up the agglomerated powder, so that the agglomerated powder becomes smaller particles, which fall above the iron plate 22 and are heated by the combustion tube 26.
