Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, in particular to a granulation device and a granulation process based on overflow sand milling, circulating slurry extraction and glue fine grinding. Background Art

[0002] Soft ferrite, as the name suggests, is a magnetic material. Its application feature is "magnetic conductivity". Just like metals are conductive, some materials are magnetic, which we call magnetic materials. Magnetic materials are divided into hard magnetic and soft magnetic. The so-called hard magnetic material is a permanent magnet. It does not require an external energized solenoid to have magnetism, and the magnetism will not disappear. Soft magnets themselves are not magnetic. Only when an external energized solenoid is added will a magnetic field be generated. When the external current is removed, the magnetic field no longer exists.

[0003] Granulating equipment is a device that can extrude raw materials into particles of different sizes, so that the granular materials can be used in different fields.

[0004] Before sintering soft ferrites, the iron oxide raw material (generally industrial rust is used as the main raw material, and its main component is iron oxide) needs to be ground and granulated. At present, the granulators on the market only have the basic function of extruding granulation by adhesive bonding when granulating. Therefore, the existing granulators cannot realize the integrated work of guided conveying and integrated drying before and after the granulation of the iron oxide raw materials.

[0015] A manufacturing process based on overflow sand milling, circulating slurry extraction and glue fine grinding, which includes the following steps:

[0016] S1. First, put the material particles into the overflow sand mill device to perform basic grinding work. At the same time, while the material is being ground, the filling device can be started to pump slurry and stir the glue. Then the overflow sand mill device is turned on, and the formed material particles will flow into the interior of the central mechanism;

[0017] S2. After that, the material particles will flow downward along the surface of the guide inclined plate to the inside of the storage cavity. When the storage cavity maintains a normal state, the first plastic wheel and the second plastic wheel are in contact, and the second motor can be started to drive the second gear and the third gear to rotate at the same time, so that the second plastic wheel drives the first plastic wheel and the blades to rotate, so that the granular material inside the storage cavity can be turned over. At the same time, the guide pipe can be connected to the external hot air blower, so that the guide pipe can continuously transport hot air to the inside of the storage cavity, thereby improving the drying efficiency of the granular material inside the storage cavity.

[0018] S3. Finally, when the granular material inside the storage cavity is dried, the first motor can be started to drive the threaded rod to rotate, causing the storage cavity to move toward the front end. When the storage cavity moves, the sealing plate can be driven to contact the bottom end of the U-shaped bracket, causing the sealing plate to move toward the rear end, causing the granular material to be discharged outward from the front bottom of the storage cavity, thereby completing the discharge of the granular material.

[0019] Beneficial effects of the present invention:

[0020] First, the present invention can start the first motor through the setting of the collecting device, drive the threaded rod to rotate, so that the storage cavity can be moved, and when the storage cavity is moving, it can drive the sealing plate to contact the bottom end of the U-shaped bracket, and the sealing plate can be blocked by the blocking of the U-shaped bracket, so that the storage cavity is misaligned with the sealing plate when moving, so that the particulate material in the storage cavity is discharged from the inside of the storage cavity, and at the same time, the sealing plate can be prevented from falling by sliding on the supporting round rod, thereby completing the work of guiding and conveying the particulate material.

[0021] Second, the present invention adopts the combination setting of the interception device and the synchronous starting component. When the guide inclined plate transmits the granular material, it can be discharged into the interior of the storage cavity through the docking device. When the storage cavity maintains a normal state, the first plastic rubber wheel can be driven to contact the second plastic rubber wheel, and the second motor can be started to drive the second gear and the third gear to rotate at the same time, so that the second plastic rubber wheel drives the first plastic rubber wheel and the blades to rotate, so that the granular material inside the storage cavity can be turned over. At the same time, the guide duct can be coordinated with the external hot air blower, so that the hot air can be discharged into the interior of the storage cavity. Through the coordination of the guide duct and the blades, the granular material inside the storage cavity can be turned over and dried, thereby improving the drying efficiency of the granular material.

The second plastic rubber wheel 35 and the first plastic rubber wheel 14 are both provided with anti-slip patterns on the outer rings, so that the friction between the second plastic rubber wheel 35 and the first plastic rubber wheel 14 can be improved.

[0043] The granulating device 4 is fixedly mounted on the top of the guide inclined plate 22, the front end of the storage chamber 11 is threadedly sleeved on the threaded rod 26, the connecting frame 36 is fixedly mounted on the front end bottom of the guide inclined plate 22, and the end of the connecting frame 33 away from the third gear 34 is fixedly mounted on the guide inclined plate 22. The guide pipe 37 is vertically aligned with the storage chamber 11, and can transfer hot air to the interior of the storage chamber 11.

[0044] A positioning frame is fixedly installed on the front end of the motor 5, and the overflow sand grinding device 2 is fixedly installed on the positioning frame, the L-shaped push plate 10 is horizontally aligned with the second piston rod 23, the blocking plate 20 is vertically aligned with the guide inclined plate 22, and the sealing plate 13 is fixedly installed with limiting plates on both ends away from the first return spring 15, the top of the storage cavity 11 is in contact with the bottom surface of the docking device 25, and the bottom end of the U-shaped bracket 28 is horizontally aligned with the limiting plate, which can limit and block the sealing plate 13, making it convenient for the sealing plate 13 to be misaligned with the discharge port at the bottom of the storage cavity 11.

[0045] The interior of the docking device 25 is set in a hollow state, and the docking device 25 is communicated with the storage cavity 11. A discharge hole is opened at the front bottom of the storage cavity 11. The interior of the special-shaped gas cylinder 24 is set in a hollow state, and a closed cavity is formed between the first piston rod 19, the special-shaped gas cylinder 24 and the second piston rod 23. The top surface of the guide inclined plate 22 is set at a 45° slope, and the lowest point of the guide inclined plate 22 is flush with the rear end top of the docking device 25, so that the granular material on the guide inclined plate 22 can be transferred to the interior of the docking device 25.

[0046] The manufacturing process based on overflow sand milling circulation slurry extraction and glue fine grinding using the above granulation device includes the following steps:

[0047] S1. First, the material particles are placed in the overflow sand mill 2 to perform basic grinding work. At the same time, while the material is being ground, the filling device 3 can be started to pump the slurry and stir the glue. Then, the overflow sand mill 2 is turned on, and the formed material particles will flow into the interior of the centralizing mechanism 1.

[0048] S2, after that, the material particles will flow downward along the surface of the guide inclined plate 22 to the inside of the storage cavity 11. When the storage cavity 11 is kept in a normal state, the first plastic rubber wheel 14 and the second plastic rubber wheel 35 are in contact with each other, and the second motor 31 can be started to drive the second gear 30 and the third gear 34 to rotate at the same time, so that the second plastic rubber wheel 35 drives the first plastic rubber wheel 14 and the blade 12 to rotate, so that the granular material inside the storage cavity 11 can be turned over. At the same time, the guide pipe 37 can be connected to the external hot air blower, so that the guide pipe 37 can continuously transport hot air to the inside of the storage cavity 11, thereby improving the drying efficiency of the granular material inside the storage cavity 11. At the same time, when the second gear 30 rotates, it can drive the flip plate 29 to rotate at the same time, and when the flip plate 29 rotates, it is in contact with the top surface of the connecting frame 36, so that the connection between the connecting frame 36 and the guide inclined plate 22 can be prevented from being blocked;

[0049] S3. Finally, when the granular material inside the storage cavity 11 is dried, the first motor 27 can be started to drive the threaded rod 26 to rotate, causing the storage cavity 11 to move toward the front end. When the storage cavity 11 is moving, the sealing plate 13 can be driven to contact the bottom end of the U-shaped bracket 28, causing the sealing plate 13 to move toward the rear end, causing the granular material to be discharged outward from the front bottom of the storage cavity 11, completing the discharge of the granular material.

[0050] The working principle of embodiment 1 is as follows: when in use, firstly put the raw materials from outside into the overflow sand mill 2 for sand milling, so that the particle size of the raw materials is uniform and consistent, which is beneficial to the subsequent granulation. At the same time, the filling device 3 can be started to make the raw materials inside the overflow sand mill 2 to extract the slurry and stir the glue. When the overflow sand mill 2 and the filling device 3 are in use, the overflow sand mill 2 is installed on the motor 5, and the motor 5 is fixedly installed on the support frame, and the support frame is slidably sleeved on the support shaft on the granulation device 4, so that when the motor 5 is started, it can drive the first gear 7 to rotate, and when the first gear 7 rotates, it can move on the rack 6, so that the overflow sand mill 2 and the filling device 3 can be driven to slide back and forth on the granulation device 4, through The overflow sand mill 2 moves back and forth on the granulator 4, and the overflow sand mill 2 can be opened to allow the stirred raw materials to enter the granulator 4. The raw materials can be made into granular raw materials by passing through the granulator 4. When the granular raw materials pass through the granulator 4 and enter the top of the guide ramp 22, the top of the guide ramp 22 is set at a 45° slope, and the guide ramp 22 fits with the connecting frame 36, so that the raw materials pass through the connecting frame 36 and enter the interior of the storage cavity 11. When the storage cavity 11 maintains a normal state, the first plastic wheel 14 will fit with the second plastic wheel 35, and the second motor 31 can be started to drive the second gear 30 to rotate. When the second gear 30 rotates, it can drive the flip plate 29 to rotate, and the flip plate 2 When the second gear 30 rotates, it fits with the top surface of the connecting frame 36, so that when the flip plate 29 rotates, the granular material at the joint of the connecting frame 36 and the guide inclined plate 22 can be pushed into the inside of the connecting frame 36 to prevent the granular material from accumulating between the connecting frame 36 and the guide inclined plate 22. At the same time, when the second gear 30 rotates, it can drive the transmission toothed belt 32 to rotate at the same time, and when the transmission toothed belt 32 rotates, it can drive the third gear 34 and the second plastic wheel 35 to rotate at the same time, so that the second plastic wheel 35 can drive the first plastic wheel 14 and the blade 12 to rotate. The blade 12 is located inside the storage cavity 11, so that when the blade 12 rotates, the granular material inside the storage cavity 11 can be stirred. At the same time, the guide pipe 37 can be connected to the outside The hot air blower 36 is connected to the storage cavity 11, so that the hot air can be transmitted to the interior of the storage cavity 11 by the guide pipe 37. The blades 12 rotate and cooperate with the guide pipe 37, so that the granular materials in the storage cavity 11 can be turned over and blown, which can improve the drying efficiency of the granular materials and prevent the granular materials from sticking together. When the granular materials in the storage cavity 11 have completed the drying work, the first motor 27 can be started to drive the threaded rod 26 to rotate. When the threaded rod 26 rotates, it can drive the storage cavity 11 to move toward the front end, so that the storage cavity 11 drives the sealing plate 13 to contact the bottom end of the U-shaped bracket 28. The sealing plate 13 can be squeezed by the restriction of the U-shaped bracket 28. At the same time, when the storage cavity 11 moves toward the front end, the sealing plate 13 will be misaligned with the bottom end of the storage cavity 11.Thus, the discharge port at the bottom of the storage cavity 11 can be exposed, so that the granular material inside the storage cavity 11 will be discharged downward, completing the guided conveying of the granular material. At the same time, when the storage cavity 11 moves toward the front end, it can drive the L-shaped push plate 10 to disengage from the second piston rod 23. At this time, the blocking plate 20 will move downward along the inside of the support frame 21, so that the blocking plate 20 will move downward to contact the surface of the guide inclined plate 22, thereby preventing the guide inclined plate 22 from transmitting materials again. Conversely, when the storage cavity 11 moves toward the rear end to be vertically aligned with the connecting frame 36, it can drive the L-shaped push plate 10 to disengage from the second piston rod 23. The plate 10 squeezes the second piston rod 23 into the interior of the special-shaped gas cylinder 24, thereby compressing the gas inside the special-shaped gas cylinder 24, driving the first piston rod 19 and the blocking plate 20 to move upward at the same time, so that the blocking plate 20 can be misaligned with the surface of the guide inclined plate 22, allowing the top of the guide inclined plate 22 to transmit granular materials. At the same time, when the storage cavity 11 is reset to the rear end, the elasticity of the first reset spring 15 will drive the sealing plate 13 to move to the front end again until the sealing plate 13 blocks the discharge port at the bottom of the storage cavity 11 again, preventing the granular materials from leaking out from the interior of the storage cavity 11, and completing the work.

[0051] Example 2

[0052] On the basis of Example 1, Fig.10 As shown, the support frame 21 further includes a second return spring 38 , and the second return spring 38 is symmetrically fixedly mounted on the top end of the support frame 21 .

[0053] When implementing this embodiment, when the second piston rod 23 loses the squeezing force, the elasticity of the second return spring 38 will drive the blocking plate 20 and the first piston rod 19 to move downward rapidly, so that the tightness of the blocking plate 20 and the guide inclined plate 22 can be improved.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
