It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0032] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an electric heating container for improving the roundness of powder.
[0033] Example 1:
[0034] Combination Figure 1-5As shown, the present invention provides an electric heating container for improving the roundness of powder, including a repair mechanism 100, a protection mechanism 200 and a feeding mechanism 300. The repair mechanism 100 includes a graphite container 110, a conductive electrode 120 connected to the bottom of the inner cavity of the graphite container 110, a power line 130 connected to the top of the conductive electrode 120, a heat-insulating jacket 140 sleeved on the outside of the graphite container 110, and an insulating jacket 150 sleeved on the outside of the heat-insulating jacket 140.
[0035] The protection mechanism 200 includes a protective outer shell 210 sleeved on the outside of the insulating outer shell 150 and a cover 220 attached to the top of the protective outer shell 210. The power cord 130 is vertical and movably passes through the top of the cover 220.
[0036] The feeding mechanism 300 includes a feeding channel 310 that extends vertically through the cover 220, a frame 320 that is movably sleeved on the top of the feeding channel 310, a leather bag 330 that connects the feeding channel 310 and the frame 320, a drawstring 340 that connects to the opening of the leather bag 330, and a pressure plate 350 that is attached to one side of the leather bag 330 and snapped into the frame 320.
[0037] Furthermore, the top of the graphite container 110 is fixed with an annular steep slope 600, the top of which fits against the top of the inner cavity of the shell cover 220. The annular steep slope 600 is provided to prevent powdery raw materials from remaining on the surface of the annular steep slope 600 and to avoid material waste.
[0038] Furthermore, the wall thickness of the thermal insulation jacket 140 is greater than the wall thickness of the graphite container 110, and the wall thickness of the graphite container 110 is greater than the wall thickness of the insulating jacket 150. The sum of the wall thicknesses of the three is equal to the thickness of the bottom of the annular steep slope 600. This size design effectively prevents raw materials from remaining on the top of the graphite container 110, the top of the thermal insulation jacket 140, and the top of the insulating jacket 150.
[0039] Furthermore, the bottom end of the feeding channel 310 extends into the interior of the graphite container 110. Both the feeding channel 310 and the frame 320 are made of insulating material. The installation of the feeding channel 310 ensures that all the raw materials can fall into the interior of the graphite container 110.
[0040] Furthermore, two fasteners 700 are connected between the protective shell 210 and the cover 220. The two fasteners 700 are located on both sides of the protective shell 210. The fasteners 700 can fasten the protective shell 210 and the cover 220 to ensure more stable operation in the process of improving the roundness of powder.
[0041] Example 2:
[0042] Combination Figure 2-3 As shown, based on Embodiment 1, a protective cover 400 is installed at the bottom of the inner cavity of the graphite container 110, the conductive electrode 120 is located inside the protective cover 400, and the power line 130 runs vertically through the top of the protective cover 400. The protective cover 400 can protect the conductive electrode 120 and prevent the conductive electrode 120 from being damaged by the weight of the powdered raw material.
[0043] Example 3:
[0044] Combination Figure 2 As shown, in the above embodiment, a plurality of brackets 500 are fixedly connected to the bottom of the inner cavity of the protective shell 210. The plurality of brackets 500 are equally spaced and form a ring around the bottom of the insulating jacket 150. The brackets 500 can improve the installation firmness of the insulating jacket 150 inside the protective shell 210.
[0045] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the control frame 320 is first laid flat, and then powdered raw materials are put into the bag 330. The raw materials are then supported by the pressure plate 350. When the bag opening of the bag 330 is about to be blocked, the tie rope 340 is tightened. Then the frame 320 is erected, and the powdered raw materials fall into the graphite container 110, effectively preventing powder dust. Then, the staff taps the protective shell 210 to make the vibration force penetrate into the graphite container 110 and compact the powdered raw materials. Then, the external power supply is connected, and the DC power heats the conductive electrode 120, which repairs the sharp corners of the microscopic particles of the powder. This solves the problems of low initial discharge efficiency and low slurry solid content caused by the large specific surface area of the material, and improves the adhesion between the negative electrode material and the foil.
