[0004] However, the above-mentioned solutions are inconvenient for breaking up and preventing blockages in the plastic powder material. In actual storage and use, some plastic powder material will clump together, and bridging will occur during feeding, resulting in poor subsequent feeding. Therefore, it is necessary to design a storage device for plastic powder production. Utility Model Content

[0012] Preferably, the drying assembly includes: a fixed base fixedly connected to the middle position of the top wall of the chamber, the lower end of the inner wall of the fixed base forming a rotating structure with the surface of the hollow rotating rod, through holes being opened at equal angles inside the fixed base at the upper end of the surface of the hollow rotating rod, and one-way air outlets being provided at equal intervals at the lower end of the surface of the hollow rotating rod; a drying chamber fixedly connected to one side of the top of the chamber, the bottom end of the drying chamber communicating with the interior of the fixed base through a conduit, a heating wire fixedly connected to the inner wall of the drying chamber, a filter fixedly connected to one side of the drying chamber, and an air inlet pipe fixedly connected to one side of the filter; a one-way exhaust pipe fixedly connected to the upper end of one side of the chamber, and a humidity sensor fixedly connected to one side of the top of the chamber.

[0017] 2. The drying components can heat and dehumidify the plastic powder material inside the chamber. The humidity sensor can automatically detect the humidity inside the chamber. When the humidity is too high, the heating wire and drive motor can be activated to rotate and heat the material for dehumidification. When the humidity drops, it can be turned off to avoid excessive energy consumption or damage to the plastic powder material caused by continuous heating. This enables automatic heating and dehumidification. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Example 1

[0027] A preferred embodiment of the powder production storage device provided by this utility model is, for example... Figures 1 to 5 As shown: A storage device for plastic powder production includes a silo body 2; a controller 3 fixedly connected to the upper front end of the silo body 2; a feed pipe 6 fixedly connected to one side of the top of the silo body 2; a discharge pipe 4 fixedly connected to the middle position of the bottom end of the silo body 2; an anti-blocking component 5 assembled on one side of the bottom end of the silo body 2, which is used to prevent vibration and blockage of the discharge pipe 4; a drive motor 7 fixedly connected to the middle position of the top of the silo body 2, the output end of the drive motor 7 extending into the interior of the silo body 2 and fixedly connected to a hollow rotating rod 11 through a coupling; and a drying component 1 assembled at the upper end of the silo body 2, which is used to dry and dehumidify the interior of the silo body 2.

[0028] It should be noted that some existing storage devices for plastic powder production still have certain shortcomings in actual use. According to the comparison documents, some plastic powder material may clump during actual storage and use, and bridging may occur during feeding, resulting in subsequent feeding difficulties.

[0029] In this embodiment, the plastic powder material is added into the silo 2 through the feed pipe 6. During the storage of the plastic powder material, the drying component 1 can be used to automatically heat and dehumidify the inside of the silo 2, effectively preventing the humidity inside the silo 2 from being too high. The drive motor 7 can be started to drive the hollow rotating rod 11 to rotate, which in turn drives the scraper 8 and the fixed rod 9 to rotate, stirring and dispersing the material, further preventing the material from clumping. The rotating screw rod 10 spirally conveys the material at the lower end of the silo 2 upwards, increasing the contact area with the hot air. At the same time, during the discharge process through the discharge pipe 4, the reverse rotation of the screw rod 10 can spirally convey the plastic powder material downwards, making it easier for the material to enter the discharge pipe 4 and be discharged. The anti-clogging component 5 can be used to vibrate and prevent clogging of the discharge pipe 4, further improving the smoothness of the discharge.

[0030] In a further preferred embodiment of this utility model, the anti-blocking component 5 includes: a fixed frame 501 fixedly connected to one side of the bottom end of the chamber 2, a reduction motor 509 fixedly connected to the bottom end of one side of the fixed frame 501, and a cam 508 fixedly connected to the output end of the reduction motor 509 via a coupling; a slide rod 502 fixedly connected to the lower end of one side of the fixed frame 501, a slider 504 slidably connected to the surface of the slide rod 502, a sliding plate 506 fixedly connected to the bottom end of the slider 504, a rubber block 505 fixedly connected to one side of the sliding plate 506, and a fixing block 507 fixedly connected to the other side of the sliding plate 506; and a fixing spring 503 wound around the surface of the slide rod 502, with both ends of the fixing spring 503 fixedly connected to one side of the slide rod 502 and one side of the slider 504, respectively.

[0031] In this embodiment, the cam 508 is rotated by starting the reduction motor 509, and periodically contacts the fixed block 507. This causes the sliding plate 506 to slide and drive the slider 504 to slide on the surface of the slide rod 502, compressing the fixed spring 503. At the same time, the sliding plate 506 will cause the rubber block 505 to slide and collide with the surface of the discharge pipe 4. After the cam 508 rotates and separates from the fixed block 507, the elastic force of the fixed spring 503 can be used to make the slider 504 interact and drive the sliding plate 506 to slide back to its original position. Then, the sliding plate 506 slides back and forth and drives the rubber block 505 to periodically collide with the surface of the discharge pipe 4, thereby achieving vibration anti-blocking of the discharge pipe 4.

[0032] In a further preferred embodiment of the present invention, one side of the rubber block 505 is arc-shaped, and the rubber block 505 is fixedly connected to one side of the sliding plate 506 by bolts.

[0033] In this embodiment, an arc-shaped rubber block 505 is used to facilitate more comprehensive contact and collision with the surface of the discharge pipe 4.

[0034] In a further preferred embodiment of the present invention, the fixing block 507 is semi-circular in shape, and the fixing block 507 and the cam 508 are in the same horizontal plane.

[0035] In this embodiment, a semi-circular fixing block 507 is used to facilitate its rotational contact with the cam 508, thereby allowing the sliding plate 506 to slide.

[0036] In a further preferred embodiment of this utility model, a scraper 8 is fixedly connected to one side of the surface of the hollow rotating rod 11, and a fixing rod 9 is fixedly connected to the inner wall of the scraper 8 at equal intervals.

[0037] In this embodiment, the rotation of the scraper 8 and the fixing rod 9 can agitate and disperse the plastic powder material inside the chamber 2, preventing the material from clumping.

[0038] In a further preferred embodiment of the present invention, a spiral rod 10 is fixedly connected to the bottom end of the hollow rotating rod 11, and the top end of the spiral rod 10 is fixedly connected to the bottom end of the hollow rotating rod 11 by bolts.

[0039] In this embodiment, during the dehumidification process, the screw rod 10 rotates to transport the plastic powder material at the lower end of the chamber 2 upwards, while during discharge, the screw rod 10 rotates in the opposite direction to transport the material downwards, so that it can be discharged through the discharge pipe 4.

[0040] Example 2

[0041] Based on Example 1, a preferred embodiment of the powder storage device for plastic powder production provided by this utility model is as follows: Figures 1 to 5 As shown: The drying assembly 1 includes: a fixed base 108 fixedly connected to the middle position of the top wall inside the chamber 2, the lower end of the inner wall of the fixed base 108 and the surface of the hollow rotating rod 11 forming a rotating structure, through holes 109 are opened at equal angles inside the fixed base 108 at the upper end of the surface of the hollow rotating rod 11, and one-way air outlets 104 are provided at equal intervals at the lower end of the surface of the hollow rotating rod 11; a drying chamber 110 fixedly connected to one side of the top of the chamber 2, the bottom end of the drying chamber 110 communicating with the interior of the fixed base 108 through a conduit, a heating wire 105 fixedly connected to the inner wall of the drying chamber 110, a filter 106 fixedly connected to one side of the drying chamber 110, and an air inlet pipe 103 fixedly connected to one side of the filter 106; a one-way exhaust pipe 102 fixedly connected to the upper end of one side of the chamber 2, and a humidity sensor 101 fixedly connected to one side of the top of the chamber 2.

[0042] In this embodiment, the air inlet pipe 103 is connected to an external blower or other ventilation equipment. During the storage process in the chamber 2, the humidity sensor 101 detects the humidity inside the chamber 2. When the humidity is higher than a predetermined value, the external blower operates to filter the outside air through the filter 106 and deliver it into the drying chamber 110. At the same time, the heating wire 105 is activated to heat the incoming gas, so that the hot air is delivered to the fixed base 108 through the duct, and then delivered to the hollow rotating rod 11 through the through hole 109. It is then blown evenly into the chamber 2 through the one-way air outlet 104, thereby heating and dehumidifying the plastic powder material. The humid air is then filtered through the filter screen 107 and discharged through the one-way exhaust pipe 102. At the same time, the filter screen 107 can prevent the plastic powder from being discharged through the one-way exhaust pipe 102.

[0043] In a further preferred embodiment of the present invention, a filter screen 107 is fixedly connected to the inner wall of the compartment 2 at one end of the one-way exhaust pipe 102 by bolts, and the cross-sectional area of ​​the filter screen 107 is larger than the cross-sectional area of ​​the opening at one end of the one-way exhaust pipe 102.

[0044] In this embodiment, the filter screen 107 can be used to prevent plastic powder from being discharged through the one-way exhaust pipe 102.

[0045] In a further preferred embodiment of this utility model, the heating wire 105 is serpentine in shape, and both ends of the heating wire 105 are fixedly connected to the inner wall of the drying oven 110 by bolts.

[0046] In this embodiment, a serpentine heating wire 105 is used to increase its heating area, reduce heating dead zones, and facilitate faster heat entry into the fixed base 108.

[0047] In summary, by using the drying component 1, the rotating scraper 8, and the fixed rod 9, the plastic powder material inside the silo 2 is agitated, heated, and dehumidified to prevent the material from clumping. At the same time, the anti-clogging component 5 and the screw rod 10 enable the discharge pipe 4 to vibrate and prevent clogging, thus facilitating the smoother discharge of the plastic powder material through the discharge pipe 4.
