Abstract

The utility model provides an extruder which is applied to the technical field of extruders. The extruder comprises a discharging barrel installed on one side of the top of an extruder shell, a transverse rod is connected with the inner circumferential face of the discharging barrel in a clamped mode through a connecting groove, the shape of a magnetic attraction block is consistent with that of the transverse rod, the transverse rod is made of magnetic metal, the magnetism of the magnetic attraction block installed in the transverse rod can be diffused to the outer portion of the transverse rod, and therefore the magnetic attraction effect is improved. When recycled powder is fed into the extruder shell through the discharging barrel, the powder penetrates through the discharging barrel, in the process that the powder enters the discharging barrel, iron products mixed in the powder are influenced by magnetism generated by the magnetic attraction blocks installed in the transverse rods and are attracted to the surfaces of the transverse rods, and therefore the effect that the iron products are attracted to the surfaces of the transverse rods is achieved. In this way, it can be avoided that iron products enter the squeezing machine along with powder, damage to the squeezing machine is caused, unsmooth production is caused, and meanwhile the maintenance cost of the squeezing machine is increased.

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] like Figure 1-Figure 3 As shown, an extruder comprises:

[0023] The discharge barrel 1 is installed on one side of the top of the extruder housing, and a plurality of connecting grooves 101 are arranged in the discharge barrel 1. The connecting grooves 101 are provided with cross bars 102. A magnetic block is fixedly installed inside the cross bars 102. Four connecting grooves 101 are optimally arranged, and the central axes of the two connecting grooves 101 farthest apart are perpendicular to each other, and the length of the connecting grooves 101 is less than the height of the discharge barrel 1. The cross bars 102 are composed of a magnetic metal structure that is a "cross" shape when viewed from above. The cross bars 102 are connected to the inner circumference of the discharge barrel 1 through the connecting grooves 101. The shape of the magnetic block is consistent with that of the cross bars 102. The cross bars 102 composed of magnetic metal can be used to make the inner The magnetism of the magnetic block installed in the upper part can diffuse to the outside of the cross bar 102. When the recovered powder is sent into the extruder housing through the discharge barrel 1, the powder passes through the discharge barrel 1. In the process of the powder entering the discharge barrel 1, the iron products mixed therein are affected by the magnetism generated by the magnetic block installed inside the cross bar 102 and are adsorbed on the surface of the cross bar 102, thereby preventing the iron products from entering the squeezer with the powder and causing damage to the squeezer, causing production problems and increasing the maintenance cost of the extruder. The cross bar 102 is clamped with the connecting groove 101, so that the cross bar 102 can be easily removed from the discharge barrel 1 and the iron products adsorbed on its surface can be cleaned.

[0024] A cylindrical cavity 4 is provided at the middle end of the above-mentioned extruder housing, and a sealing block 401 is detachably installed at one end of the cavity 4 located on the side of the extruder housing. When the sealing block 401 is connected to the cavity 4, a closed cavity 4 is formed. A motor 402 is detachably installed on one side of the sealing block 401, and the output end of the motor 402 is detachably connected to one end of the extrusion rod 403, and the other end of the extrusion rod 403 is rotatably connected to the middle end of the other side of the cavity 4. The output end of the motor 402 is used to drive the extrusion rod 403 to rotate in the cavity 4, wherein the extrusion rod 403 is a frustum-shaped structure made of metal material, and a plurality of threads are provided on its outer wall. The top end of the extrusion rod 403 is close to the sealing block 401 and is located directly below the discharge barrel 1 at the same time. The gap between the cavity 4 and the extrusion rod 403 gradually decreases from the top to the end of the extrusion rod 403, and then as the extrusion rod 403 rotates, the moisture in the powder is squeezed out to achieve drying of the recovered powder.

[0025] A water collecting box 2 is provided on one side of the bottom surface of the extruder shell, and a powder collecting box 3 is provided on the other side. The water collecting box 2 is used to collect water generated in the process of drying the powder, and the powder collecting box 3 is used to collect the dried powder. A water outlet trough 5 is provided on one side of the bottom surface of the extruder shell, and the water outlet trough 5 is used to discharge the water in the cavity 4 into the water collecting box 2. A barrier net 501 is fixedly installed inside the water outlet trough 5 to block the powder through the barrier net 501 to prevent the powder from leaking out of the cavity 4 through the water outlet trough 5. A powder outlet 6 is provided on the other side of the bottom surface of the extruder shell, and a powder discharge pipe 601 is fixedly installed at the front end of the powder outlet 6. The dried powder enters the powder discharge pipe 601 through the powder outlet 6 and is discharged into the powder collecting box 3 for collection.

[0026] The cross bar 102 is clamped with the inner circumference of the discharge barrel 1 through the connecting groove 101. The shape of the magnetic block is consistent with the shape of the cross bar 102. The cross bar 102 is made of magnetic metal, so that the magnetism of the magnetic block installed inside can diffuse to the outside of the cross bar 102. When the recovered powder is sent into the extruder housing through the discharge barrel 1, the powder passes through the discharge barrel 1. In the process of the powder entering the discharge barrel 1, the iron products mixed therein are affected by the magnetism generated by the magnetic block installed inside the cross bar 102 and are adsorbed on the surface of the cross bar 102, so that the iron products are adsorbed on the surface of the cross bar 102, thereby preventing the iron products from entering the squeezer with the powder and causing damage to the squeezer, causing production problems and increasing the maintenance cost of the extruder.

[0027] Working principle: When in use, the recovered powder is sent into the cavity 4 through the discharge barrel 1, and the iron products mixed in the powder are adsorbed on the surface of the cross bar 102. When the powder enters the cavity 4, the motor 402 is started, driving the extrusion rod 403 to rotate to extrude the powder and dry the powder. The water generated during the extrusion process is discharged into the water collecting box 2 through the water outlet trough 5. The dried powder is sent to the powder outlet 6 as the extrusion rod 403 rotates, and is sent to the powder collection box 3 through the powder discharge pipe 601 for collection.

[0028] The feed barrel, water collecting box, powder collecting box, cavity, water outlet trough, powder outlet, connecting groove, cross bar, sealing block, motor, extrusion rod, barrier net and powder discharge pipe are all universal standard parts or are known through conventional experimental methods, so no more detailed records are made here.
