Description

Technical Field

[0001] The utility model belongs to the technical field of plastic masterbatch production, and particularly relates to plastic masterbatch magnetic separation equipment. Background Art

[0002] During the production of plastic masterbatches, magnetic impurities such as iron filings and iron powder may be introduced due to factors such as raw materials, equipment, and the processing environment. If these impurities remain in the plastic masterbatch, they will not only affect the product's appearance and performance, but may also adversely affect subsequent processing and use. Magnetic separation can effectively remove these magnetic impurities, improving the purity and quality of the plastic masterbatch.

[0003] The magnetic separation process for plastic masterbatch requires a magnetic separation device, which typically includes a permanent magnet or electromagnet assembly. A conveying device, such as a conveyor belt, may also be used during the magnetic separation process. In some cases, the plastic masterbatch is poured onto a conveyor, which then drives the masterbatch toward the magnetic separation device, where magnetic impurities are removed. A thick layer of plastic masterbatch often forms on the conveyor, with more magnetic impurities confined to the inner or lower end of the layer. Masterbatch outside the layer can affect the magnetic separation device's ability to attract magnetic impurities. Conveyors generally lack the ability to disperse the masterbatch, resulting in lower-than-expected magnetic separation results. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a plastic masterbatch magnetic separation device to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides a plastic masterbatch magnetic separation device, comprising:

[0006] The loading part has a loading cavity with an upward opening, the loading cavity is used to load the masterbatch, and a feed port communicating with the loading cavity is provided on the side wall of the loading part;

[0007] a horizontal driving portion, mounted at the bottom of the loading portion, for driving the loading portion to reciprocate along a first direction to disperse the masterbatch in the loading cavity;

[0008] And a magnetic separation component, including a vertical driving part and a magnetic separation part connected to each other, the vertical driving part can drive the magnetic separation part to move back and forth in the vertical direction, and the magnetic separation part is used to remove magnetic impurities.

[0009] This design can prevent the accumulation of masterbatch from affecting the magnetic separation component's attraction to magnetic impurities.

[0010] Preferably, the vertical driving part is installed on the loading part, and the horizontal driving part can synchronously drive the vertical driving part and the loading part to move; the size of the magnetic separation part is adapted to the size of the loading cavity opening.

[0011] With this design, the magnetic separation part and the loading part move synchronously. During the shaking process of the loading part, the magnetic separation part can promptly attract magnetic impurities entering the outside of the mother particle layer, thereby improving the magnetic separation effect and accelerating the magnetic separation progress.

[0012] Preferably, the vertical driving part is arranged separately from the horizontal driving part and the loading part.

[0013] This design avoids the need to connect the vertical drive unit to the horizontal drive unit, avoids the need to perform drilling, welding or other processing on both, and reduces the burden on the horizontal drive unit.

[0014] Preferably, the loading portion is provided with a discharge port communicating with the loading cavity, and a blocking member is provided at the discharge port for blocking the discharge port opening, and the blocking member is detachably mounted on the loading portion.

[0015] This design facilitates the transfer of masterbatches from the loading chamber.

[0016] Preferably, a support portion is provided at the bottom of the horizontal driving portion, and the support portion can be raised and lowered in the vertical direction to adjust the position of the loading portion in the vertical direction.

[0017] With this design, the support portion can be raised and lowered in the vertical direction to adjust the vertical height of the loading portion, making it easier for the collecting device to receive the masterbatch, and especially making it easier for the loading portion to be used in conjunction with collecting devices of different sizes.

[0018] Preferably, the loading part is movable relative to the horizontal driving part; a driving member is provided on the supporting part, and the output end of the driving member can move in the vertical direction so that the loading part is tilted, thereby facilitating the mother particles in the loading cavity to leave the loading cavity through the discharge port.

[0019] With such a design, the other end of the bottom of the loading part can be separated from the horizontal driving part under the push of the output end of the driving member, so that the loading part is tilted, and the masterbatch leaves the loading cavity through the discharge port under the action of gravity.

[0020] Preferably, a guide plate is provided at the opening of the feed port, and the guide plate is detachably mounted on the loading portion, and is used to guide the masterbatch into the loading cavity.

[0021] This design facilitates the feeding process in some cases.

[0022] Preferably, a collecting box is provided on one side of the supporting portion, and the collecting box is used to collect the masterbatch leaving the loading cavity.

[0023] With this design, the collection box can collect several batches of masterbatch at one time.

[0024] Preferably, the outer wall of the collection box is provided with a plurality of protruding structures, and the protruding structures are all combined with the outer wall of the collection box to form grooves.

[0025] This design makes it easier for operators to carry the collection box.

[0026] The beneficial effects of the present invention are as follows: by setting a horizontal driving part to achieve the purpose of dispersing the master particles in the loading chamber, it is possible to avoid the accumulation of master particles affecting the attraction effect of the magnetic separation component on magnetic impurities. When a large number of master particles cover the outside of the magnetic impurities, the above-mentioned attraction effect will be weakened, resulting in more magnetic impurities still remaining in the master particle layer after the magnetic separation process, making the magnetic separation effect less than expected.

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1

[0049] like Figures 1 to 6 As shown, the utility model provides a plastic masterbatch magnetic separation device, comprising:

[0050] The loading part 1 has a loading cavity 11 with an upward opening, the loading cavity 11 is used to load the masterbatch, and a feed port 12 is provided on the side wall of the loading part 1 and communicates with the loading cavity 11;

[0051] The horizontal driving unit 2 is installed at the bottom of the loading unit 1 and is used to drive the loading unit 1 to move back and forth along a first direction to disperse the masterbatch in the loading chamber 11;

[0052] The magnetic separation component 3 includes a vertical driving part 31 and a magnetic separation part 32 connected to each other. The vertical driving part 31 can drive the magnetic separation part 32 to move back and forth in the vertical direction. The magnetic separation part 32 is used to remove magnetic impurities.

[0053] The first direction is the x direction in the figure; the first direction is parallel to the horizontal direction.

[0054] Optionally, the magnetic separation part 32 is configured as a permanent magnet.

[0055] The magnetic separation part 32 can be configured as a magnetic plate or a plurality of magnetic bars distributed in an array, or both can be configured simultaneously; the magnetic separation part 32 can also be configured as an electromagnet assembly.

[0056] When the magnetic separation part 32 is configured as a magnetic plate or a magnetic bar, it is usually made of high-performance permanent magnetic material (such as neodymium iron boron) and has a strong magnetic field strength and stable magnetism.

[0057] The magnetic separation process is explained by setting the magnetic separation section 32 as a plurality of array-distributed magnetic rods, as follows: the magnetic rod array forms multiple local strong magnetic field areas. When the mother particles enter these areas, the magnetic material will be attracted by the magnetic rods and adhere to the magnetic rods; the spacing and arrangement between the magnetic rods will affect the distribution and intensity of the magnetic field, thereby affecting the sorting effect. By adjusting the spacing and arrangement of the magnetic rods, the sorting effect can be optimized.

[0058] When the magnetic separation part 32 is set as an electromagnet assembly, the electromagnet assembly consists of an electromagnet, an iron core and a control circuit. The electromagnet generates a magnetic field when it is energized and the magnetic field disappears when the power is off. The electromagnet assembly can adjust the magnetic field strength and direction as needed. The principle is as follows: when the electromagnet is energized, a strong magnetic field is generated to attract the magnetic material in the master particle, and the magnetic material is captured by the electromagnet and held in the magnetic field; when cleaning is required, the power can be turned off to make the magnetic field disappear, and the magnetic material can be easily fallen off; the control circuit can accurately control the on and off time and current of the electromagnet, thereby adjusting the magnetic field strength and sorting effect.

[0059] The operator transfers the masterbatch to the loading chamber 11 through the feed port 12, and the masterbatch gathers in the loading chamber 11 to form a masterbatch layer. Then the horizontal drive unit 2 drives the loading unit 1 to move back and forth along the first direction to disperse the masterbatch in the loading chamber 11. Then the magnetic separation component 3 removes the magnetic impurities in the masterbatch layer to separate the masterbatch from the magnetic impurities.

[0060] The horizontal driving part 2 drives the loading part 1 to move back and forth along the first direction to achieve the effect of shaking the loading part 1, and the master particles in the master particle layer are dispersed under the action of inertia.

[0061] Optionally, the vertical driving portion 31 and the horizontal driving portion 2 are configured as electric slides or similar existing devices that can drive an object to move along a straight line.

[0062] By setting up a horizontal driving part 2, the purpose of dispersing the master particles in the loading chamber 11 can be achieved, and the accumulation of master particles can be avoided to affect the attraction effect of the magnetic separation component 3 on magnetic impurities. When a large number of master particles cover the outside of the magnetic impurities, the above-mentioned attraction effect will be weakened, resulting in more magnetic impurities still remaining in the master particle layer after the magnetic separation process, making the magnetic separation effect less than expected.

[0063] Due to the limitation of the loading chamber 11 , when the height of the loading chamber 11 itself is relatively high, there is no need to worry about the masterbatch being scattered on the ground or other areas during the process of dispersing the masterbatch.

[0064] Optionally, the bottom wall of the feed port 12 is inclined.

[0065] It should be emphasized that the purpose of the present invention is mainly to improve the magnetic separation effect so that the magnetic separation effect is at least not lower than expected, and the magnetic separation progress can also be ensured by setting up multiple magnetic separation equipment.

[0066] It should also be emphasized that, for the two connected structures in the present invention, when it is not emphasized that they are integrated, the two connected structures are regarded as being separable during replacement and other processes.

[0067] Example 2

[0068] In this embodiment, the vertical driving part 31 is installed on the loading part 1, and the horizontal driving part 2 can synchronously drive the vertical driving part 31 and the loading part 1 to move; the size of the magnetic separation part 32 is adapted to the size of the opening of the loading chamber 11.

[0069] For this embodiment, an implementation process is provided as a reference: the magnetic separation section 32 is always placed in the loading chamber 11. During the shaking process of the loading chamber 11, the magnetic separation section 32 can restrict the master particles in the loading chamber 11 from leaving the loading chamber 11 through the opening of the loading chamber 11, especially when the loading chamber 11 itself is at a low height. The magnetic separation section 32 moves synchronously with the loading chamber 1. During the shaking process of the loading chamber 11, the magnetic separation section 32 can promptly attract magnetic impurities that enter the outer side of the master particle layer, thereby improving the magnetic separation effect and accelerating the magnetic separation process. Initially, the magnetic separation section 32 is at a certain height to facilitate the master particles to enter the loading chamber 11. Subsequently, the magnetic separation section 32 moves downward to facilitate magnetic separation.

[0070] It should be noted that the vertical drive unit 31 can also be installed on the horizontal drive unit 2, but in this setting, when the magnetic separation unit 32 can completely block the opening of the loading chamber 11, if the loading unit 1 needs to be gradually tilted, the magnetic separation unit 32 can easily hinder the implementation of this process.

[0071] Example 3

[0072] In this embodiment, the vertical driving portion 31 is disposed separately from the horizontal driving portion 2 and the loading portion 1 .

[0073] When the vertical driving portion 31 is provided separately from the horizontal driving portion 2 , the vertical driving portion 31 may be connected to other structures, such as the supporting portion 5 described below.

[0074] Through the arrangement in this embodiment, it is avoided that the vertical drive part 31 needs to be connected to the horizontal drive part 2 or the loading part 1, and it is avoided that the horizontal drive part 2 or the loading part 1 needs to be drilled, welded or otherwise processed, which also reduces the burden on the horizontal drive part 2.

[0075] When the vertical drive unit 31 is set separately from the horizontal drive unit 2 and the loading unit 1, the vertical drive unit 31 and the loading unit 1 cannot move synchronously. The horizontal drive unit 2 needs to drive the loading unit 1 to the magnetic separation area (which can be set to the initial position in some cases) after shaking the loading unit 1, and then magnetic separation can be performed. Under such a setting, the feed port 12 can be cancelled, but the height of the loading unit 1 needs to be adjusted according to actual conditions to avoid leakage of the masterbatch.

[0076] Optionally, when the loading portion 1 is in a predetermined position, magnetic separation and discharge can be performed; the predetermined position can be set to an initial position or other positions according to actual conditions.

[0077] Example 4

[0078] In this embodiment, the loading portion 1 is provided with a discharge port 13 connected to the loading chamber 11 , and a blocking member 4 is provided at the discharge port 13 for blocking the opening of the discharge port 13 . The blocking member 4 is detachably mounted on the loading portion 1 .

[0079] The discharging port 13 is provided to facilitate the transfer of the masterbatch from the loading chamber 11 .

[0080] The discharge port 13 may be rectangular and communicate with the bottom end of the loading chamber 11 .

[0081] Optionally, along the vertical direction, the bottom wall of the discharge port 13 and the bottom wall of the loading chamber 11 are in the same plane.

[0082] The blocking member 4 is mounted on the loading portion 1 and is movable relative to the loading portion 1, including but not limited to rotation and sliding. For example, the blocking member 4 is slidably mounted on the loading portion 1 and its moving direction is perpendicular to the first direction.

[0083] Example 5

[0084] In this embodiment, a support portion 5 is provided at the bottom of the horizontal driving portion 2 , and the support portion 5 can be raised and lowered in the vertical direction to adjust the position of the loading portion 1 in the vertical direction.

[0085] Optionally, the support portion 5 is configured as a scissor lift. The support portion 5 may also include a lifting plate and a plurality of scissor lifts arranged side by side, wherein the plurality of scissor lifts jointly drive the lifting plate to move in the vertical direction, and the horizontal driving portion 2 is mounted on the lifting plate.

[0086] In some cases, the vertical driving portion 31 may be connected to the supporting portion 5 .

[0087] After the masterbatch leaves the loading chamber 11, it needs to be collected by a collecting device such as a collecting bucket. The support portion 5 can be raised and lowered in the vertical direction to adjust the position of the loading portion 1 in the vertical direction, so that the collecting device can receive the masterbatch, especially the loading portion 1 can be used in conjunction with collecting devices of different sizes.

[0088] Example 6

[0089] In this embodiment, the loading part 1 can be moved relative to the horizontal driving part 2; a driving member 6 is provided on the supporting part 5, and the output end of the driving member 6 can be moved in the vertical direction so that the loading part 1 is tilted, thereby facilitating the mother particles in the loading chamber 11 to leave the loading chamber 11 through the discharge port 13.

[0090] Optionally, the driving member 6 is configured as a cylinder, an electric push rod or similar existing devices.

[0091] The loading part 1 can be moved relative to the horizontal driving part 2. For example, one end of the bottom of the loading part 1 close to the discharge port 13 is rotatably connected to the horizontal driving part 2, and the other end of the bottom of the loading part 1 can be separated from the horizontal driving part 2 under the push of the output end of the driving member 6, so that the loading part 1 is set at an angle, and the masterbatch leaves the loading chamber 11 through the discharge port 13 under the action of gravity.

[0092] As for the specific connection method between the loading part 1 and the horizontal driving part 2, an example is given here as a reference: the horizontal driving part 2 is set to two, the two horizontal driving parts 2 include a sliding seat 21, and a rotating shaft 14 is provided between the two sliding seats 21. The rotating shaft 14 can rotate around its own axis relative to the two sliding seats 21, and the loading part 1 is connected to the rotating shaft 14.

[0093] The driving member 6 includes an output end and a non-output end. The non-output end of the driving member 6 is connected to the support portion 5. For example, the support portion 5 is configured as a scissors-type lift. The scissors-type lift has a top seat. The horizontal driving portion 2 and the driving member 6 are both installed on the top seat. The non-output end of the driving member 6 is placed below the top seat. The top seat is provided with a through hole for the output end of the driving member 6 to pass through.

[0094] In some cases, the horizontal drive unit 2 may include a movable plate and multiple electric slides. The multiple electric slides collectively drive the movable plate to move horizontally, and one end of the bottom of the loading section 1 is rotatably mounted on the movable plate. The output end of the driving member 6 can contact the loading section 1 through the gap between the electric slides.

[0095] In some cases, the driving member 6 includes a support plate and a plurality of driving cylinders, a non-output end of each driving cylinder is connected to the support plate, and the support plate is mounted on the supporting portion 5 .

[0097] In this embodiment, a guide plate 7 is provided at the opening of the feed port 12 . The guide plate 7 is detachably mounted on the loading portion 1 . The guide plate 7 is used to guide the masterbatch into the loading chamber 11 .

[0098] The guide plate 7 may include a main plate and two sub-plates. The main plate is inclined to guide the masterbatch. The two sub-plates are installed at both ends of the main plate to limit the movable range of the masterbatch and thus prevent the masterbatch from leaking out.

[0099] Example 8

[0100] In this embodiment, a collecting box 8 is provided on one side of the supporting portion 5 , and the collecting box 8 is used to collect the master batches leaving the loading chamber 11 .

[0101] The size of the collecting box 8 needs to be adjusted according to actual conditions. The collecting box 8 can collect several batches of masterbatches at one time.

[0102] Example 9

[0103] In this embodiment, a plurality of protruding structures 9 are provided on the outer wall of the collection box 8 , and the protruding structures 9 and the outer wall of the collection box 8 are combined to form grooves 10 .

[0104] The provision of the protruding structure 9 makes it easier for the operator to carry the collection box 8 and to apply force to the collection box 8, and the provision of the groove 10 further enhances this effect.

[0105] Example 10

[0106] In this embodiment, the bottom wall of the loading chamber 11 is magnetic.

[0107] The loading portion 1 may be a box-shaped structure having a bottom plate, which constitutes the bottom wall of the loading cavity 11 . The bottom plate may be configured as a magnetic plate, which can improve the screening effect of magnetic impurities.

[0108] Optionally, a single or multiple raised structures (not shown) are installed on the sidewall of the loading chamber 11. The raised structures can be raised rods, etc., which can limit the movement range of the master particles so that magnetic impurities on the inner or bottom side of the master particle layer can move to the upper side of the master particle layer, facilitating magnetic separation of the magnetic impurities.
