DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0031] As Figures 1-3 shown, a powder mixing device for producing a high-temperature resistant spherical α-aluminum oxide powder flame retardant,

[0032] comprises:

[0033] tank body 1;

[0034] a filter plate 6 symmetrically arranged in the tank body 1 and driven to reciprocate;

[0035] a mixing tray 12 rotatably arranged in the tank body 1 and driven to rotate reciprocally;

[0036] mixing rods 13 arranged in a circumferential array on the mixing tray 12.

[0037] Specifically, when the high-temperature resistant spherical α-aluminum oxide powder needs to be fused with other raw materials, workers pour the high-temperature resistant spherical α-aluminum oxide powder and other raw materials into the feed port at the top of the tank body 1 simultaneously, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials slide down along the feed port onto the filter plate 6. By driving the filter plate 6 to reciprocate, the filter plate 6 can filter out impurities in the high-temperature resistant spherical α-aluminum oxide powder and other raw materials, avoiding the doping of some pollutants in the powder material. Moreover, the surface of the filter plate 6 is uneven, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials can be mixed during the reciprocating movement of the filter plate 6, thereby improving the mixing efficiency of the high-temperature resistant spherical α-aluminum oxide powder and other raw materials. When the high-temperature resistant spherical α-aluminum oxide powder and other raw materials pass through the filter plate 6, they will fall onto the mixing tray 12. By driving the mixing tray 12 to rotate reciprocally, the mixing rods 13 installed on the mixing tray 12 can stir the high-temperature resistant spherical α-aluminum oxide powder and other raw materials at a high frequency during the reciprocating rotation process, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials can be quickly mixed.

[0038] In the above-mentioned embodiment, by arranging the filter plate 6, the mixing tray 12 and the mixing rods 13 in the tank body 1, the high-temperature resistant spherical α-aluminum oxide powder and other flame retardant raw materials entering the tank body 1 can be quickly and fully fused. By driving the filter plate 6 to reciprocate, the filter plate 6 with uneven end faces can oscillate the high-temperature resistant spherical α-aluminum oxide powder and other raw materials entering the tank body 1 simultaneously, so as to achieve the effect of preliminary fusion. And the filter plate 6 filters out the pollutants doped in the high-temperature resistant spherical α-aluminum oxide powder and other raw materials. The filtered high-temperature resistant spherical α-aluminum oxide powder and other raw materials will fall into the mixing tray 12 for secondary mixing. By driving the mixing tray 12 to rotate reciprocally at a high frequency, the mixing tray 12 drives the mixing rods 13 to stir the high-temperature resistant spherical α-aluminum oxide powder and other raw materials reciprocally and at a high frequency, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials can be quickly and fully mixed, not only improving the mixing efficiency of the high-temperature resistant spherical α-aluminum oxide powder and other raw materials, but also avoiding the doping of other pollutants in the powdered flame retardant.

[0039] As a further embodiment provided by the present utility model, a chute 3 is opened in the tank body 1, a frame 4 is movably installed in the chute 3, tooth buckles 5 are symmetrically arranged on the frame 4, and a filter plate 6 is movably connected to the side wall of the frame 4.

[0040] Furthermore, the end face of the filter plate 6 is uneven.

[0041] Even further, an annular block 7 is movably installed in the chute 3, tooth columns 8 arranged in a circumferential array are provided on the side wall of the annular block 7, and the tooth columns 8 are meshed with the tooth buckles 5.

[0042] Specifically, by driving the annular block 7 to rotate, the rotation of the annular block 7 drives the tooth column 8 to rotate during the rotation process. Through the meshing of the tooth column 8 and the tooth buckle 5, the tooth column 8 can drive the frame 4 to reciprocate in the chute 3, so that the frame 4 can drive the filter plate 6 to reciprocate. Since the end face of the filter plate 6 is uneven, during the reciprocating movement of the filter plate 6, it can not only filter the high-temperature resistant spherical α-aluminum oxide powder and other flame retardant raw materials, but also preliminarily mix the high-temperature resistant spherical α-aluminum oxide powder and other flame retardant raw materials, thereby improving the mixing efficiency of the high-temperature resistant spherical α-aluminum oxide powder and other flame retardant raw materials.

[0043] As another embodiment further provided by the present utility model, a first motor 9 is fixedly installed on the side wall of the tank body 1, and the output end of the first motor 9 is fixedly connected to the annular block 7.

[0044] Specifically, by driving the annular block 7 to rotate by the first motor 9, the annular block 7 can drive the frame 4 and the filter plate 6 to reciprocate through the cooperation of the tooth column 8 and the tooth buckle 5.

[0045] As another embodiment further provided by the present utility model, a box body 10 is fixedly installed at the bottom end of the tank body 1. A transmission shaft 11 is movably installed in the box body 10. One end of the transmission shaft 11 is fixedly connected to the mixing tray 12, and a gear 16 is fixedly installed on the side wall of the transmission shaft 11.

[0046] Specifically, by driving the gear 16 to reciprocally rotate, the gear 16 can drive the transmission shaft 11 to reciprocally rotate, so that the transmission shaft 11 can drive the mixing tray 12 to reciprocally rotate to mix the materials.

[0047] As another embodiment further provided by the present utility model, a second motor 19 is fixedly installed in the box body 10. A circular frame 18 is fixedly installed at the top end of the second motor 19. A rotating shaft 17 is movably installed on the circular frame 18. A rack 15 is movably installed on the side wall of the rotating shaft 17, and the rack 15 meshes with the gear 16.

[0048] Specifically, by driving the circular frame 18 to rotate by the second motor 19, the circular frame 18 drives the rotating shaft 17 to rotate. By driving the rack 15 to reciprocally move through the rotating shaft 17, the rack 15 drives the gear 16 to reciprocally rotate during the reciprocating movement process. During the rotation process of the gear 16, the gear 16 drives the transmission shaft 11 to rotate, so that the transmission shaft 11 can drive the mixing tray 12 to reciprocally rotate.

[0049] As another embodiment further provided by the present utility model, a fixing frame 2 is movably installed in the box body 10, and the rack 15 is movably connected in the fixing frame 2.

[0050] Specifically, the rack 15 is restricted by the fixing frame 2, so that the rack 15 can always remain engaged with the gear 16, enabling the rack 15 to continuously and stably drive the gear 16 to rotate reciprocally.

[0051] As another embodiment further provided by the present utility model, a material discharge groove 14 is provided on the side wall of the mixing tray 12.

[0052] Specifically, after the high-temperature resistant spherical α-aluminum oxide powder and other raw materials are mixed well, through the material discharge groove 14 provided on the mixing tray 12, the mixed high-temperature resistant spherical α-aluminum oxide powder and other raw materials can fall along the material discharge groove 14 to the bottom of the tank body 1 for storage, and the worker can take out the fully mixed flame retardant through the discharge port of the tank body 1.

[0053] Working principle: When the high-temperature resistant spherical α-aluminum oxide powder needs to be mixed with other raw materials, the worker pours the high-temperature resistant spherical α-aluminum oxide powder and other raw materials into the feed port of the tank body 1 at the same time, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials fall along the feed port onto the filter plate 6. The first motor 9 drives the annular block 7 to drive the tooth column 8 to rotate, so that the tooth column 8 cooperates with the tooth buckle 5 to drive the frame 4 to move reciprocally, thereby enabling the frame 4 to drive the filter plate 6 to move reciprocally. Through the uneven end face of the filter plate 6, the high-temperature resistant spherical α-aluminum oxide powder and other raw materials can be preliminarily mixed during the filtering process. When the high-temperature resistant spherical α-aluminum oxide powder and other raw materials pass through the filter plate 6 and fall onto the mixing tray 12, the second motor 19 drives the circular frame 18 to drive the rotating shaft 17 to rotate, so that the rotating shaft 17 drives the rack 15 to move reciprocally, thereby enabling the rack 15 to drive the gear 16 to rotate reciprocally during the reciprocating movement. The gear 16 drives the transmission shaft 11 to rotate reciprocally, so that the transmission shaft 11 drives the mixing tray 12 to rotate reciprocally. Through the reciprocating rotation of the mixing tray 12, the mixing rods 13 installed on the mixing tray 12 can agitate the high-temperature resistant spherical α-aluminum oxide powder and other raw materials at a high frequency during the reciprocating rotation process, so that the high-temperature resistant spherical α-aluminum oxide powder and other raw materials can be quickly mixed, and the mixed high-temperature resistant spherical α-aluminum oxide powder and other raw materials pass through the material discharge groove 14 and accumulate at the bottom of the tank body 1, and the worker can take away the mixed flame retardant powder from the discharge port.
