Description

Technical Field

[0001] The utility model relates to the technical field of magnetic material processing equipment, in particular to a water mixing and grinding device. Background Art

[0002] Magnets that retain their magnetism over a long period of time are called permanent magnets. Examples include natural magnetite (magnetite) and artificial magnets (aluminum-nickel-cobalt alloy). Besides permanent magnets, there are also electromagnets that require an electric current to activate their magnetism. Permanent magnets, also called hard magnets, are not easily demagnetized or magnetized.

[0003] When processing magnetic materials, it is necessary to grind the magnetic materials. For example, the invention patent with publication number CN112742554A, entitled Grinding Cylinder and Grinding Machine, discloses that the grinding cylinder includes an inner cylinder, an outer cylinder, and a flow guide. The inner cylinder is formed with a grinding cavity for accommodating materials and grinding media, and the outer wall of the inner cylinder has a blind hole; the outer cylinder is arranged outside the inner cylinder, and a first cavity is formed between the inner cylinder and the outer cylinder, and the first cavity is isolated from the grinding cavity; the flow guide is provided with a flow guide channel, the flow guide channel is isolated from the first cavity, and one end of the flow guide channel is connected to the blind hole.

[0004] When the above-mentioned grinding device is actually used, driving the grinding drum to rotate and the collision of the added grinding balls (grinding beads) with the material will produce a large noise, which may not only cause health problems for workers in this environment, but also lead to distraction, increased fatigue and other problems that affect work efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a water mixing and grinding device, which is used to solve the technical problem raised in the background art that the noise generated by the existing grinding device greatly affects the health and work efficiency of personnel.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A water mixing grinding device comprises a shell, wherein a grinding cylinder is rotatably arranged in the shell, a feed hole is provided at the axis center of one side of the grinding cylinder, a feed assembly is provided in the feed hole, a drive assembly for driving the grinding cylinder to rotate and simultaneously driving the feed assembly to work is provided on one side of the shell, a discharge hole is provided at the axis center of one side of the grinding cylinder away from the feed hole, an extraction pipe connected to an external extraction device is provided on the discharge hole, a vacuum layer is provided between the shell and the grinding cylinder, and a soundproof cover is provided on one side of the shell for covering the feed assembly and the drive assembly.

[0008] Working principle:

[0009] This device is a water mixing and grinding device, which is mainly used to mix magnetic materials with water and other additives.

[0010] During use, the shell is first vacuumed, and then the magnetic material, water and additives with the correct proportions are added into the feed assembly. The feed assembly is operated by operating the drive assembly, and a number of grinding balls are added to the feed assembly at the same time, so that the material and the grinding balls in the feed assembly are transported to the grinding drum together. The grinding drum is then rotated in the shell by operating the drive assembly, so that the material is mixed in the grinding drum through collision and rotation with the grinding balls to form the required slurry. The mixed slurry is finally extracted to the next process through the discharge hole and extraction pipe on the grinding drum.

[0011] The desired effects obtained:

[0012] First, a vacuum layer and a silent cover are provided, which can effectively reduce the noise generated when the grinding cylinder rotates through the vacuum layer, and the silent cover can effectively reduce the noise generated by the feeding component and the driving component during operation.

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] According to Figures 1 to 3 This device is a water mixing grinding device, including a shell 1, in which a grinding cylinder 2 is rotatably installed. A feed hole 3 is opened at the axis center of one side of the grinding cylinder 2, and a discharge hole 4 is opened at the axis center of the side of the grinding cylinder 2 away from the feed hole 3. A first rotating shaft 8 and a second rotating shaft 9 with both ends passing through are respectively fixed at the axis centers of both sides of the grinding cylinder 2. The first rotating shaft 8 and the second rotating shaft 9 are respectively rotatably connected to the shell 1 and extend outward from the shell 1 along the axial direction of the grinding cylinder 2. The first rotating shaft 8 and the second rotating shaft 9 are both rotatably connected to the side wall of the shell 1 through bearings and sealing rings. The first rotating shaft 8 is connected to the feed hole 3, and the second rotating shaft 9 is connected to the discharge hole 4. A feeding assembly is provided in the feeding hole 3, and the feeding assembly includes a feeding barrel 10 with a top opening, a feeding rod 11 and a spiral blade 12. The feeding barrel 10 is rotatably connected to the first rotating shaft 8. A feeding pipe 26 is provided at the opening of the feeding barrel 10. The feeding rod 11 is coaxial with the first rotating shaft 8 and is rotatably arranged in the feeding barrel 10. One end of the feeding rod 11 passes through the first rotating shaft 8 and extends into the feeding hole 3. The other end of the feeding rod 11 extends away from the feeding hole 3 and extends out of the feeding barrel 10. The spiral blade 12 is evenly fixed on the feeding rod 11, and the end of the spiral blade slides against the inner side wall of the feeding barrel 10. This arrangement allows the material to be added to the opening of the feeding barrel 10 and driven to drive the spiral blade 12 so that the material can enter the grinding barrel 2 conveniently.

[0021] like Figure 1 As shown, one side of the housing 1 is provided with a drive assembly for driving the grinding cylinder 2 to rotate and at the same time for driving the feeding assembly to work, the drive assembly includes a motor 13, a driving rod 14, two first pulleys 15, a first belt 16, two second pulleys 17 and a second belt 18, the motor 13 is fixed in the silent cover 7, the driving rod 14 is fixed at the output end of the motor 13, the two first pulleys 15 are respectively fixed on the driving rod 14 and the first rotating shaft 8, the first belt 16 is sleeved between the two first pulleys 15, the two second pulleys 17 are respectively fixed on the driving rod 14 and the feeding rod 11, and the second belt 18 is sleeved between the two second pulleys 17. This arrangement can effectively drive the driving rod 14 to rotate through the motor 13, and drive the first rotating shaft 8 to rotate through the two first pulleys 15 and the first belt 16, thereby driving the grinding cylinder 2 to rotate, and driving the feeding rod 11 to rotate through the two second pulleys 17 and the second belt 18.

[0022] like Figure 1As shown, the discharge hole 4 is connected to an extraction pipe 5 connected to an external extraction device. A filter screen 24 is provided in the discharge hole 4, and a valve 25 is provided on the extraction pipe 5. A vacuum layer 6 is provided between the housing 1 and the grinding cylinder 2. The housing 1 is provided with a hole for connecting to a vacuum pump. A silent cover 7 is provided on one side of the housing 1 for housing the entire feed assembly and drive assembly. Figure 2 As shown, the silent cover 7 is provided with an adjustment member for adjusting the tightness of the second belt 18. The adjustment member includes a cylinder 19, a connecting block 20, and a third pulley 21. The cylinder 19 is fixed to the inner wall of the silent cover 7. The connecting block 20 is fixed to the telescopic end of the cylinder 19. The third pulley 21 is rotatably mounted on the connecting block 20 and is located on a section of the second belt 18 between the two second pulleys 17. This arrangement can effectively adjust the tightness of the second belt 18. The cylinder 19 drives the connecting block 20 and the third pulley 21 to move, so that the third pulley 21 tightens the second belt 18, facilitating the motor 13 to drive the feed rod 11 to rotate. When the third pulley 21 releases the tension on the second belt 18, the motor 13 speed can be adjusted after transporting the material, and the rotation speed of the grinding drum 2 can be increased. At this time, the feed rod 11 will not be driven to rotate due to the slack of the second belt 18, thereby protecting the service life of the entire feed assembly.

[0023] like Figure 1 and Figure 3 As shown, the grinding drum 2 is a frustum. The feed hole 3 is located at the end of the grinding drum 2 with a larger diameter, and the discharge hole 4 is located at the end of the grinding drum 2 with a smaller diameter. The grinding drum 2 is provided with continuous guide ribs 22 that are spirally distributed toward the discharge hole 4. The grinding drum 2 is also provided with a plurality of protrusions 23 distributed circumferentially along the inner wall of the grinding drum 2. The protrusions 23 are distributed more densely along the axial direction of the grinding drum 2 toward the discharge hole 4. The spiral guide ribs 22 allow the material inside to be impacted, crushed, and mixed, while simultaneously moving toward the discharge hole 4 as the grinding drum 2 rotates. The protrusions 23 effectively improve the collision efficiency of the internal grinding beads.

[0024] Working principle:

[0025] During use, the shell 1 is first vacuumed through an external vacuum device, and then the magnetic material, water and additives with the correct proportions are added into the feed pipe 26. The driving rod 14 is rotated by operating the motor 13, and the feeding rod 11 is driven to rotate by the two second pulleys 17 and the second belt 18, so that the spiral blade 12 on the feeding rod 11 drives the material to move into the grinding cylinder 2. When the material and grinding balls have all entered the grinding cylinder 2, the second belt 18 is loosened by operating the cylinder 19, and the speed of the motor 13 is adjusted to rotate the driving rod 14 and drive the first rotating shaft 8 to rotate by the two first pulleys 15 and the first belt 16, thereby driving the grinding cylinder 2 to rotate. The material is mixed in the grinding cylinder 2 through collision and rotation with the grinding balls to form the required slurry. The mixed slurry is finally extracted to the next process through the discharge hole 4 and the extraction pipe 5 on the grinding cylinder 2.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
