Description

Technical Field

[0001] This utility model relates to the field of ferrite magnet processing, specifically a sintering device for ferrite magnet processing. Background Technology

[0002] Ferrite magnets are permanent magnets primarily made from SrO or BaO and Fe2O3. Compared to other permanent magnets, ferrite magnets are hard and brittle, with lower magnetic energy. However, they are not easily demagnetized or corroded, and their production process is simple and inexpensive. Therefore, ferrite magnets have the highest production volume in the entire magnet industry and are widely used in industrial production. Maintaining a suitable oxygen concentration is necessary during the sintering process of ferrite magnets, requiring a sintering device specifically designed for ferrite magnet processing. Utility Model Content

[0005] Preferably, an air supply pipe is installed on the left side of the air pump, and an oxygen pipe is installed at the rear end of the air supply pipe. Oxygen and dust-free air are mixed in the air supply pipe and injected into the sintering chamber to ensure the oxygen content inside the sintering chamber and achieve better sintering results.

[0006] Preferably, an oxygen cylinder is installed at the rear end of the oxygen tube, and the oxygen cylinder and the oxygen tube are connected by threads. The oxygen cylinder injects oxygen into the gas filling tube through the oxygen tube, and the oxygen tube is equipped with an electrically controlled valve to control the amount of oxygen added.

[0007] Preferably, an exhaust pipe is installed on the right side of the sintering chamber, and the exhaust pipe is embedded in the sintering chamber. The hot gas discharged from the exhaust pipe can be passed into the preheating device to reduce the energy consumption of preheating raw materials.

[0008] Preferably, the inside of the insulation door is equipped with an observation window, and the observation window is embedded in the insulation door, so that the observation window can facilitate the observation of the internal sintering status.

[0009] Preferably, heating wires are embedded in the upper and lower side walls of the sintering chamber, and a fixing component is provided on one side of the heating wires. The heating wires on the upper and lower sides heat the raw material in the middle evenly, resulting in a better sintering effect.

[0010] Preferably, the fixing component includes a heat-resistant mesh and a clamping mesh, and the clamping mesh is rotatably connected above the heat-resistant mesh. The raw material is placed on the heat-resistant mesh and clamped by the clamping mesh to prevent the airflow from blowing the raw material.

[0011] Preferably, a pulley is provided below the heat-resistant mesh, and a side frame is installed around the pulley. The heat-resistant mesh is slid onto the side frame by the pulley, which facilitates feeding.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the raw material is placed on the heat-resistant mesh and clamped with a mesh to prevent the airflow from blowing the raw material away. The heat-resistant mesh is slid onto the side frame by pulleys for easy loading. The heating wires on the upper and lower sides heat the raw material in the middle evenly, resulting in better sintering. The handle is heat-insulated to prevent burns when opening the heat-resistant door. The observation window facilitates observation of the internal sintering status. During the sintering process, the air pump draws in air through the air inlet pipe, the dust filter screen filters dust from the air, and the oxygen cylinder injects oxygen into the oxygen supply pipe through the oxygen pipe. The oxygen pipe is equipped with an electrically controlled valve to control the amount of oxygen added. The oxygen and dust-free air are mixed in the oxygen supply pipe and injected into the sintering chamber to ensure the oxygen content inside the sintering chamber, resulting in better sintering.
