The purpose of heating high chromium forging with electric heating furnace mainly includes changing the organizational structure, increasing hardness, eliminating stress and improving processing performance.

[0003] When using an electric heating furnace, some harmful gases, such as carbon monoxide, may be produced. These gases are highly toxic and once leaked out of the furnace, they will cause serious damage to the surrounding environment and human health.

[0004] Therefore, we proposed a high-chromium forging electric heating furnace which can purify harmful gases. Utility Model Content

[0008] An inclined plate is provided inside the solid waste collection tank, and a hatch is provided on the front surface of the solid waste collection tank.

[0009] Preferably, a furnace door is rotatably connected to the front end of the heating furnace body, and electric heating rods are installed on both side surfaces inside the heating furnace body.

[0011] Preferably, both side surfaces of the placement rack are fixedly connected to the connection block, and a plurality of through holes are provided.

[0012] Preferably, the inclined plate is fixedly connected to the bottom surface of the solid waste collection trough.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model discloses an electric heating furnace for high chromium forging. When the furnace door is opened, the servo motor is driven to drive the threaded rod to rotate forward, and the front end of the placement rack can be driven to move out of the interior of the heating furnace body through the connecting block threadedly connected thereto. Figure 3 As shown, at this moment, the staff can place the high chromium forging component into the handle of the placement rack. After the processing is completed, the high chromium forging component can be taken out by reverse operation, thereby achieving the purpose of facilitating loading and unloading and increasing the overall applicability.

[0015] (1) The utility model is an electric heating furnace for high chromium forging. When the high chromium forging inside the placement rack is subjected to heat treatment inside the heating furnace body, the servo motor can be driven to drive the threaded rod to rotate rapidly and slightly forward and reverse, and then the placement rack can be driven to move rapidly and slightly forward and backward through the connecting block. When the placement rack moves rapidly forward and backward, the zirconium oxide inside the purification tank will vibrate, so that the zirconium oxide can better absorb and purify harmful gases, thereby improving the treatment effect of harmful gases.

These solid wastes after heat treatment may also cause harm to the environment and human body. Therefore, when the placement rack moves back and forth quickly, the solid waste generated inside the placement rack will be screened out, so that the solid waste will fall into the solid waste collection tank through the through hole, and then slide to the hatch by the inclined plate, so as to facilitate centralized treatment after the heat treatment process is completed, thereby avoiding the solid waste from being discharged together with the high chromium forging and causing pollution.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , an electric heating furnace for high chromium forging, comprising a heating furnace body 1, a placing rack 2 located inside the heating furnace body 1 and a solid waste collection tank 3 located at the lower end of the heating furnace body 1, driving slots 13 are provided on both sides of the heating furnace body 1, a servo motor 131 is installed at the rear end of the heating furnace body 1, a threaded rod 132 and a connecting block 133 are provided inside the driving slot 13, a through hole 21 is provided on the bottom surface of the placing rack 2, a purification tank 22 is provided around the upper surface of the placing rack 2, a carbon monoxide adsorbent is placed inside the purification tank 22, an inclined plate 31 is provided inside the solid waste collection tank 3, a hatch 32 is provided on the front surface of the solid waste collection tank 3, and the carbon monoxide adsorbent is specifically a zirconium oxide, Zirconium oxide is an excellent carbon monoxide adsorbent. It can adsorb and pyridinate carbon monoxide to form carbonates, thereby achieving carbon monoxide separation and purification. Zirconium oxide can operate stably for a long time in a high-temperature environment. It can withstand temperatures as high as 1000 degrees Celsius without losing its adsorption performance. When the high-chromium forging inside the placement rack 2 is undergoing heat treatment inside the heating furnace body 1, the servo motor 131 can be driven to drive the threaded rod 132 to rotate rapidly and slightly forward and reverse, and then the placement rack 2 can be driven through the connecting block 133 to move rapidly and slightly forward and backward. When the placement rack 2 moves rapidly forward and backward, the zirconium oxide inside the purification tank 22 will vibrate, thereby making the zirconium oxide more effective in adsorbing harmful gases.

[0025] Furthermore, the front end of the heating furnace body 1 is rotatably connected to a furnace door 11, and electric heating rods 12 are installed on both side surfaces of the interior of the heating furnace body 1. When in use, the high chromium forging components inside the heating furnace body 1 can be heat treated by the electric heating rods 12.

[0026] Furthermore, the output end of the servo motor 131 penetrates into the interior of the driving slot 13 and is transmission-connected to the threaded rod 132, and the threaded rod 132 is threadedly connected to the connecting block 133. The furnace door 11 is opened, and then the servo motor 131 is driven to drive the threaded rod 132 to rotate forward, so that the front end of the placement rack 2 can be driven to move out of the interior of the heating furnace body 1 through the connecting block 133 threadedly connected thereto. Figure 3 As shown, at this moment, the staff can place the high chromium forged component into the handle of the placement rack 2. After the processing is completed, the high chromium forged component can be taken out by reverse operation, thereby achieving the purpose of facilitating loading and unloading.

[0027] Furthermore, the two side surfaces of the placement rack 2 are fixedly connected to the connection block 133, and a plurality of through holes 21 are provided. When in use, the through holes 21 can ensure the fluidity of heat and avoid uneven heat accumulation and dispersion.

[0028] Furthermore, the inclined plate 31 is fixedly connected to the bottom surface of the solid waste collecting trough 3. During the heating process of the heat treatment furnace, some solid waste will be generated, and these solid wastes that have undergone heat treatment will also cause harm to the environment and human body. Therefore, when the placement rack 2 moves back and forth quickly, the solid waste generated inside the placement rack 2 will also be screened out, so that the solid waste falls into the solid waste collecting trough 3 through the through hole 21, and then slides from the inclined plate 31 to the hatch 32, so that after the heat treatment process is completed, it can be centrally processed to avoid pollution.

[0029] Working principle: When the utility model is used, the furnace door 11 is opened, the servo motor 131 is driven to drive the threaded rod 132 to rotate forward, and the front end of the placement rack 2 can be moved out of the interior of the heating furnace body 1 through the connecting block 133. Figure 3 As shown, at this time, it is convenient for the staff to put the high-chromium forging components into the placement rack 2 for loading, and then drive the servo motor 131 to reverse, so that the placement rack 2 can drive the high-chromium forging components into the interior of the heating furnace body 1, close the furnace door 11, and drive the electric heating rod 12 to perform heat treatment on the high-chromium forging components. During processing, the servo motor 131 can be driven to rotate quickly, slightly, and repeatedly forward and reversely, so that the placement rack 2 moves back and forth with a small amplitude. When the placement rack 2 moves back and forth with a small amplitude, the zirconium oxide inside the purification tank 22 will shake, thereby improving the adsorption effect of zirconium oxide, and at the same time, it will also drive the high-chromium forging components inside the placement rack 2 to shake, thereby screening out the solid waste generated by the heat treatment. The screened solid waste will fall into the interior of the solid waste collection tank 3 through the through hole 21 and slide to the hatch 32 by the inclined plate 31. After the heat treatment is completed, the hatch 32 is opened for centralized processing, thereby enriching the overall function and increasing the overall applicability.
