Description

Technical Field

[0001] The utility model relates to the technical field of equipment for producing ferrite cores, in particular to a ferrite core sintering thermal cycle mechanism. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials; manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss; nickel-zinc ferrite has extremely high resistivity and low magnetic permeability of less than a few hundred. Ferrite cores are used in coils and transformers of various electronic equipment.

[0003] The manganese-zinc ferrite core needs to be sintered in a sintering furnace during the sintering process. The sintering furnace is a device used to sinter powdered raw materials into hard blocks. Sintering can mix different types of powders together to form a harder and denser material. This material is often used to manufacture metals, ceramics, glass and other products. The sintering furnace uses high temperature to sinter, so that the tiny particles in the raw materials are bonded to each other through thermal action to form a whole. During the sintering process, auxiliary agents are usually required to promote the sintering process and control the properties of the sintered material. The working principle and design structure of the sintering furnace vary depending on the application field. For example, there are corresponding sintering furnace designs in steel smelting, ceramic manufacturing and other fields. A large amount of high-heat flue gas will be generated during sintering, which is generally discharged directly, but it will cause waste, and the heat cannot be recycled, which reduces the utilization rate of heat and causes a great waste of resources. Utility Model Content

[0004] The technical problem to be solved by the utility model is that most of the heat generated in the sintering furnace is directly discharged, and the heat cannot be recycled, which reduces the utilization rate of the heat and causes a great waste of resources.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a ferrite core sintering thermal circulation mechanism, including a sintering furnace, one end of which is rotatably connected to a sealed furnace door, a plurality of heating copper tubes are fixedly connected to the inner wall surface of the sintering furnace, a first fixed frame is fixedly connected to the outer wall surface of the sintering furnace, and a thermal circulation structure is arranged on one side of the sintering furnace.

[0006] The utility model is further configured such that the heat circulation structure includes a filter tank and a storage tank, a second fixing frame is fixedly connected between the filter tank and the storage tank, the second fixing frame is fixedly connected to the first fixing frame, a ventilation pipe is fixedly connected between the filter tank and the storage tank, and the interior of the filter tank is connected to the interior of the storage tank.

[0007] The utility model is further configured as follows: a first air inlet pipe is fixedly connected to the middle of the filter tank, the first air inlet pipe is fixedly connected to the sintering furnace at one end away from the filter tank, the interior of the filter tank is communicated with the interior of the sintering furnace, and first air outlet pipes are fixedly connected to both sides of the storage tank, the first air outlet pipe is fixedly connected to the sintering furnace at one end away from the storage tank, and the interior of the storage tank is communicated with the interior of the sintering furnace.

[0008] Through the above technical solution, the filter tank first filters the high-temperature gas to remove other substances therein, and finally enters the storage tank for storage, which effectively prevents the appearance of impurities in the gas recycled in the thermal cycle and improves the effect of multiple sintering.

[0009] The utility model is further configured such that a gas pipeline is fixedly connected inside the first air inlet pipe, the gas pipeline is penetrated and fixedly connected with the filter tank and the storage tank, and the penetration end of the gas pipeline is located inside the storage tank.

[0010] The utility model is further configured such that a heat-conducting pipe is fixedly connected to the through-end of the gas pipeline, a second air outlet pipe is fixedly connected to the end of the heat-conducting pipe away from the gas pipeline, the second air outlet pipe is fixedly connected to the filter tank and the storage tank through-and-through, the heat-conducting pipe and the filter tank are communicated with each other, a plurality of heat-conducting copper pipes are fixedly connected to the inside of the heat-conducting pipe, and heat sinks are fixedly connected to the two through-ends of the heat-conducting copper pipes.

[0011] Through the above technical solution, part of the gas can directly enter the filter tank for filtration, while the remaining gas passes through the gas pipeline and the heat transfer pipeline and then enters the filter tank. In this process, the filtered gas in the storage tank can be reheated, which greatly reduces the heat loss.

[0012] The utility model is further configured such that a sealing gasket is slidably connected to the inner wall of the gas pipeline, a spring is fixedly connected to the side of the sealing gasket away from the opening of the gas pipeline, an end of the spring away from the sealing gasket is fixedly connected to a limiting ring, the limiting ring is fixedly connected to the gas pipeline, a fixing column is slidably connected to the outer side of the spring, and the fixing column is fixedly connected to the gas pipeline.

[0013] Through the above technical solution, after the inside of the sintering furnace is heated, the expanding high-temperature gas will push the sealing gasket to move backward, so that the high-temperature gas can be smoothly and unidirectionally discharged into the gas storage tank, with a simple structure and convenient maintenance.

[0014] The utility model is further configured such that the second fixing frame is rotatably connected to one end of the filter tank and a curved cover plate is provided, a groove is provided on the surface of the filter tank, the curved cover plate is rotatably fitted with the surface of the filter tank, a filter net is installed on the inner side of the curved cover plate, and a handle is fixedly connected to the outer wall of the curved cover plate.

[0015] Through the above technical solution, the staff can pull open the curved cover plate through the handle to expose the filter, making it easier for the staff to replace the filter.

[0017] Through the above technical solution, the connecting plate is rotated to move the threaded column to the top of the curved cover plate. At this time, the handle is turned, the threaded column sinks and squeezes the curved cover plate to fix the curved cover plate so that it fits tightly with the filter tank, reducing the possibility of air leakage and greatly reducing heat loss.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. The utility model heats the sintering furnace by heating the copper tube after the sealed furnace door is closed. The expanded high-temperature gas pushes the sealing gasket to move backward, so that the high-temperature gas enters the heat circulation structure. Part of the gas can directly enter the filter tank for filtration, while the remaining gas passes through the gas transmission pipeline and the heat conduction pipeline, and dissipates heat through the heat conduction pipeline itself and the heat dissipation block, so as to perform secondary heating on the filtered gas in the storage tank, thereby reducing heat loss;

[0020] 2. The utility model rotates the handle to lift the threaded column and squeeze the curved cover plate, and then rotates the connecting plate to move the threaded column away from the top of the curved cover plate to unlock the curved cover plate. The staff can pull open the curved cover plate through the handle to expose the filter screen, making it convenient for the staff to replace the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS
