Description

Technical Field

[0001] The utility model relates to the technical field of demagnetization equipment, and more specifically, to automatic demagnetization equipment for metal powder. Background Art

[0002] Demagnetization equipment is a commonly used filter, which is mainly used to remove residual magnetic fields in objects. Its working principle is based on the interaction principle of magnetic fields. It is often used in equipment to remove ferrite impurities in fluids such as liquids, gases and dust.

[0003] Traditional automatic demagnetization equipment for metal powders has the following shortcomings: Traditional automatic demagnetization equipment for metal powders generally uses a sleeve to make a strong magnetic piston rod reciprocate in the sleeve. Usually, the piston rod with a strong magnet extends into the sleeve. When the outer surface of the sleeve is full of iron powder, the reciprocating motion mechanism is started to retract the piston rod, and the iron powder outside the sleeve is detached and discharged from the iron powder discharge port. During the use of this device, since the sleeve is fixed, when the material enters from the feed port, it will be directly sucked to the side of the sleeve close to the feed port, while the other side can only absorb a small amount of iron powder. When the iron powder adsorbed on the left side is thicker, it can be adsorbed to the right side. Therefore, it needs to be improved. Utility Model Content

[0023] 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.

[0024] like Figures 1 to 7 As shown, the utility model provides an automatic demagnetization device for metal powder, including a shell 1, a reciprocating motion mechanism 4 is fixedly installed on the top of the shell 1, a circular groove 2 15 is opened inside the upper end of the shell 1, a gear ring 16 is rotatably installed inside the circular groove 2 15, a sleeve 3 extending to the inside of the shell 1 is fixedly installed below the gear ring 16, a magnetic rod 5 located inside the sleeve 3 is fixedly installed below the reciprocating motion mechanism 4, a circular groove 13 is opened on the front side of the circular groove 2 15, a gear 14 is rotatably installed inside the circular groove 13, and the gear 14 is meshed with the gear ring 16.

[0025] First, when the operator is filtering the material, the servo motor 10 is started, and the servo motor 10 drives the gear 14 to rotate through the rotating shaft 12, the gear 14 drives the circular groove 15 to rotate, and the circular groove 15 drives the sleeve 3 to rotate. At this time, the fluid material is introduced from the feed pipe 2 into the shell 1 to fill the shell 1, and then the ferrite in the fluid material is captured by the magnetic field of the magnetic rod 5 and adsorbed on the outer surface of the sleeve 3. At the same time, the iron powder thickness sensor 7 will detect the adsorption thickness of the ferrite on the outer surface of the sleeve 3. Then, when the thickness of the adsorbed ferrite reaches the set value, the iron powder thickness sensor 7 will give a signal to the control system to close the valve of the feed pipe 2 and the valve of the discharge pipe 6, and then open the valve on the residual liquid discharge pipe 8. The door allows the residual material inside the shell 1 to be discharged, and then the valve of the residual liquid discharge pipe 8 is closed, and the reciprocating mechanism 4 will be started through the control system. The operation of the reciprocating mechanism 4 will drive the magnetic rod 5 to move, so that the magnetic rod 5 moves to the inside of the reciprocating mechanism 4, so that the ferrite adsorbed on the outer surface of the sleeve 3 falls off, and then the valve on the outer surface of the iron powder discharge port 9 is opened, so that it is discharged from the inside of the iron powder discharge port 9, and the valve on the iron powder discharge port 9 is closed. At the same time, the magnetic rod 5 is reset by the reciprocating mechanism 4, so that the valves on the feed pipe 2 and the discharge pipe 6 are opened, so that the adsorption operation continues, so that the ferrite can be evenly adsorbed on the outer surface of the sleeve 3, avoiding excessive adsorption on one side affecting the adsorption efficiency of the other side.

[0026] By starting the servo motor 10, the servo motor 10 drives the gear 14 to rotate through the rotating shaft 12, the gear 14 drives the circular groove 15 to rotate, the circular groove 15 drives the sleeve 3 to rotate, and the rotation of the sleeve 3 allows the ferrite to be evenly adsorbed on the outer surface of the sleeve 3. Compared with the traditional automatic demagnetization equipment for metal powders, this automatic demagnetization equipment for metal powders allows the ferrite to be evenly adsorbed on the outer surface of the sleeve 3 through the continuous rotation of the sleeve 3, thereby avoiding excessive adsorption on one side affecting the adsorption efficiency of the other side.

[0027] Among them, a residual liquid discharge pipe 8 is fixedly installed on the right side of the bottom of the shell 1, and the left end of the residual liquid discharge pipe 8 extends to the interior of the shell 1. An adjusting groove 17 is opened on the upper side of the right end of the residual liquid discharge pipe 8, and a circular groove 18 extending to the interior of the shell 1 is opened on the inner side of the adjusting groove 17. A limiting groove 19 is opened on the upper side of the left end of the residual liquid discharge pipe 8, and the limiting groove 19 is located above the circular groove 18. A movable cylinder 20 is movably installed inside the circular groove 18, and a limiting block 22 located inside the limiting groove 19 is fixedly installed on the outer side of the left end of the movable cylinder 20. A scraper 23 is fixedly installed on the outer side of the limiting block 22, and the scraper 23 corresponds to the outer wall of the residual liquid discharge pipe 8.

[0028] When the ferrite adsorbed on the outer surface of the sleeve 3 falls off, a small amount of ferrite may fall to the outside of the residual liquid discharge pipe 8. At this time, the push plate 21 is rotated to rotate inside the adjustment groove 17. The push plate 21 drives the movable cylinder 20 to rotate inside the annular groove 18, and drives the scraper 23 to rotate around the outer wall of the residual liquid discharge pipe 8 through the limit block 22, thereby cleaning the iron ore powder remaining above the residual liquid discharge pipe 8.

[0029] By rotating the push plate 21, the push plate 21 drives the movable cylinder 20 to rotate inside the annular groove 18, and drives the scraper 23 to rotate around the outer wall of the residual liquid discharge pipe 8 through the limit block 22. Compared with the traditional automatic demagnetization equipment for metal powder, this automatic demagnetization equipment for metal powder drives the scraper 23 to rotate around the outer wall of the residual liquid discharge pipe 8 through the push plate 21, thereby cleaning the iron ore powder remaining above the residual liquid discharge pipe 8 to prevent the iron ore powder from remaining above the residual liquid discharge pipe 8 and affecting the next operation.

[0030] A servo motor 10 is fixedly mounted on the inner side of the housing 1 , a protective shell 11 located outside the servo motor 10 is fixedly mounted on the inner side of the housing 1 , a rotating shaft 12 is fixedly mounted above the servo motor 10 , and the rotating shaft 12 is fixedly connected to the bottom of the gear 14 .

[0031] The servo motor 10 is started, so that the servo motor 10 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the gear 14 to rotate inside the circular groove 13, thereby driving the gear ring 16 to rotate, so that the sleeve 3 rotates.

[0032] Among them, a movable groove 24 is opened at the bottom of the scraper 23, and a telescopic block 25 is movably installed inside the movable groove 24. The front end of the telescopic block 25 corresponds to the inner wall of the shell 1, and a return spring 26 is elastically installed between the inner side of the telescopic block 25 and the inner side of the movable groove 24.

[0033] Since the inner wall of the housing 1 is distributed in an inclined surface, when the scraper 23 rotates, the return spring 26 continuously releases elastic potential energy to push the telescopic block 25 out, thereby avoiding the occurrence of cleaning dead corners.

[0034] A push plate 21 is fixedly mounted on the outer side of the right end of the movable cylinder 20 , and the push plate 21 is located inside the adjustment groove 17 .

[0035] The push plate 21 is rotated to rotate inside the adjustment groove 17 , and the push plate 21 drives the movable cylinder 20 to rotate inside the annular groove 18 , and drives the scraper 23 to rotate around the outer wall of the residual liquid discharge pipe 8 through the limit block 22 .

[0036] Among them, a feed pipe 2 is fixedly installed on the left side of the shell 1, and a discharge pipe 6 is fixedly installed on the right side of the shell 1.

[0037] The material is introduced into the interior of the housing 1 from the feed pipe 2 , and the filtered material is discharged through the discharge pipe 6 .

[0038] An iron powder discharge port 9 is provided at the bottom of the shell 1 , and an iron powder thickness sensor 7 is fixedly installed on the right side of the shell 1 .

[0039] The iron powder thickness sensor 7 will detect the thickness of the adsorbed ferrite on the outer surface of the sleeve 3. Then, when the thickness of the adsorbed ferrite reaches the set value, the iron powder thickness sensor 7 will give a signal to the control system to close the valve of the feed pipe 2 and the valve of the discharge pipe 6, and then open the valve on the residual liquid discharge pipe 8 to discharge the residual material inside the shell 1.

[0040] The working principle and use process of this utility model:

[0041] First, when the operator is filtering the material, the servo motor 10 is started, and the servo motor 10 drives the gear 14 to rotate through the rotating shaft 12, the gear 14 drives the circular groove 15 to rotate, and the circular groove 15 drives the sleeve 3 to rotate. At this time, the fluid material is introduced from the feed pipe 2 into the shell 1 to fill the shell 1, and then the ferrite in the fluid material is captured by the magnetic field of the magnetic rod 5 and adsorbed on the outer surface of the sleeve 3. At the same time, the iron powder thickness sensor 7 will detect the adsorption thickness of the ferrite on the outer surface of the sleeve 3. Then, when the thickness of the adsorbed ferrite reaches the set value, the iron powder thickness sensor 7 will give a signal to the control system to close the valve of the feed pipe 2 and the valve of the discharge pipe 6, and then open the valve on the residual liquid discharge pipe 8. The door allows the residual material inside the shell 1 to be discharged, and then the valve of the residual liquid discharge pipe 8 is closed, and the reciprocating mechanism 4 will be started through the control system. The operation of the reciprocating mechanism 4 will drive the magnetic rod 5 to move, so that the magnetic rod 5 moves to the inside of the reciprocating mechanism 4, so that the ferrite adsorbed on the outer surface of the sleeve 3 falls off, and then the valve on the outer surface of the iron powder discharge port 9 is opened, so that it is discharged from the inside of the iron powder discharge port 9, and the valve on the iron powder discharge port 9 is closed. At the same time, the magnetic rod 5 is reset by the reciprocating mechanism 4, so that the valves on the feed pipe 2 and the discharge pipe 6 are opened, so that the adsorption operation continues, so that the ferrite can be evenly adsorbed on the outer surface of the sleeve 3, avoiding excessive adsorption on one side affecting the adsorption efficiency of the other side.

[0042] When the ferrite adsorbed on the outer surface of the sleeve 3 falls off, a small amount of ferrite may fall to the outside of the residual liquid discharge pipe 8. At this time, the push plate 21 is rotated to rotate inside the adjustment groove 17. The push plate 21 drives the movable cylinder 20 to rotate inside the annular groove 18, and drives the scraper 23 to rotate around the outer wall of the residual liquid discharge pipe 8 through the limit block 22, thereby cleaning the iron ore powder remaining above the residual liquid discharge pipe 8.
