Description

Technical Field

[0001] The utility model belongs to the technical field of sintering of rotary magnetic ferrites, and more specifically, particularly relates to an electric kiln for sintering ferrites. Background Art

[0002] Gyromagnetic materials are materials with unique microwave magnetism. The sintering process is currently used for the molding of microwave magnetic materials. This can effectively avoid pollution in the process, improve the quality of the product, and ensure the consistency of microwave gyromagnetic materials and the stability of product quality. At this time, a special sintering electric kiln is required.

[0003] The existing publication number CN211876710U discloses an electric kiln for sintering gyromagnetic ferrite. By setting a rubber rotating central axis at the central axis position of the sintering inner box, the glass placement plate can be rotated, which improves the sintering effect and avoids the effect of uneven sintering.

[0004] Based on the above, the following problems were found: However, there is not only a temperature difference between the area close to the microwave guide tube and the area far from the microwave guide tube inside the electric ceramic oven, but there is also a large temperature difference between the top and bottom of the electric ceramic oven. It is still difficult to avoid uneven sintering. At the same time, the electric ceramic oven is vertically layered inside, which makes it inconvenient to pick up and place objects when sintering is completed, and it is necessary to wait for the central axis to rotate one circle while taking the object.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an electric kiln for sintering ferrite is provided, in order to achieve a more practical purpose. Utility Model Content

[0009] Furthermore, a plurality of the first connecting rods are provided, and the plurality of the first connecting rods are arranged equidistantly around the circumference, and the distance between the driven shaft and the top of the partition is greater than the sum of the length of the first connecting rod, the length of the second connecting rod and the height of the material holding frame.

[0010] Furthermore, there are two microwave generators, which are respectively located on both sides of the middle of the bottom of the electric kiln furnace body, and there are two microwave guide blocks, which are arranged corresponding to the two microwave generators.

[0011] Furthermore, transverse grooves are formed through both sides of the material holding frame, and a plurality of the transverse grooves are provided, and the plurality of material holding frames are arranged vertically and equidistantly.

[0012] Furthermore, a ventilation hole is formed through the bottom of the material holding frame, and a plurality of the ventilation holes are provided, and the plurality of ventilation holes are arranged in an equidistant manner.

[0013] Furthermore, the distance between the driven gear and the support rod and the electric kiln furnace body is greater than 5CM, and the diameter of the root circle of the driven gear is greater than the diameter of the root circle of the support rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1.

[0016] 2. In the utility model, the cover is opened, and the servo motor is rotated while the object to be sintered is placed inside the material holding frame using pliers. When some objects are sintered, the cover is opened. When the sintered objects that can be taken out are rotated to the top, the objects can be directly taken out from the material holding frame at the top using pliers, thereby achieving a more convenient effect of taking out the sintered objects.

[0017] 3. In the utility model, the servo motor drives the driving gear to rotate, which in turn drives the driven gear to rotate slowly, and drives the driven shaft and the first connecting rod to rotate, so as to avoid the servo motor and the driving gear from directly contacting the electric kiln furnace body, thereby protecting the driving device and preventing the temperature from being too high.
