Description

Technical Field

[0001] The utility model relates to the field of metallurgical furnaces, in particular to an energy-saving furnace for metallurgical environmental protection. Background Art

[0002] Metallurgical furnaces are industrial furnaces that perform thermal processing on various materials or workpieces during metallurgical production. Modern metallurgical furnaces can be divided into three categories according to different heat sources: fuel furnaces, electric furnaces, and self-heating furnaces. In addition, metallurgical furnaces using new energy sources (such as solar energy and atomic energy) as heat sources are in the development stage. Thermal processing is a processing process with the heating of materials or workpieces as an important feature, such as roasting, smelting, heating, heat treatment, drying, etc. Most of the production links of iron and steel metallurgy and nonferrous metallurgy are inseparable from furnaces. The energy consumption of the metallurgical industry depends to a large extent on the energy consumption of various metallurgical furnaces.

[0003] Most of the metallurgical furnaces in the prior art have fixed structures. When loading and unloading metal parts, it is usually necessary to manually use a clamping device to clamp the metal parts into the metallurgical furnace or take the workpieces out from the inside. This operation is not only time-consuming and labor-intensive, but also has great safety hazards, which can easily cause damage to the workpieces or burns to humans, greatly reducing the practicality of the device. At the same time, the smoke exhaust device of the existing metallurgical furnace is not convenient enough, and it is impossible to effectively and quickly replace and clean the internal filter screen. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

[0024] Preferably, the driving assembly 4 includes a fixed seat 41, a threaded rod 42 is provided on one side of the fixed seat 41, a guide rod 45 is provided on the other side of the fixed seat 41, a movable block 44 and a guide block 46 are provided on the threaded rod 42 and the guide rod 45 respectively, and a movable seat 47 is provided on the upper ends of the movable block 44 and the guide block 46. The fixed seat 41 is fixed to the front end of the metallurgical furnace 2. The movable block 44 is screwed on the threaded rod 42, and the guide block 46 is slidably sleeved on the guide rod 45. The upper end of the movable seat 47 is fixedly connected to the bottom of the outer cover plate 3, and one end of the threaded rod 42 is connected to the motor 43, and the motor 43 is installed on the outside of one side of the fixed seat 41;

[0025] The motor 43 is used to drive the threaded rod 42 to rotate, and the threaded rod 42 is used to drive the movable block 44 to move. The guide rod 45 and the guide block 46 cooperate to drive the movable seat 47 to move vertically on the fixed seat 41, so as to facilitate the movement of the outer cover plate 3. The outer cover plate 3 can drive the placement rack 5 to be moved out of the metallurgical furnace 2, so that the metal to be smelted can be placed on the placement rack 5 or the metal that has been smelted can be taken out. The operation is simple and safe.

[0026] Preferably, the filter assembly 7 comprises an outer frame 71, a filter screen 72 is arranged inside the outer frame 71, a sealing cover 73 is arranged outside the outer frame 71, a gear 74 and a rack rod 75 are movably arranged inside the sealing cover 73, a knob 76 is fixedly connected to the outer end of the gear 74, the outer frame 71 and the filter screen 72 are plugged into the smoke exhaust box 6, the gear 74 is meshed with the rack rod 75, and the outer end of the rack rod 75 passes through the sealing cover 73 and is correspondingly plugged into the limiting hole 61;
