[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-Figure 3 The utility model provides an embodiment of an energy-saving and environmentally friendly electric furnace device, including a box body 1, which is a box-type electric furnace in the existing technology center. The inner wall of the box body 1 is provided with a placing component 3, and the inner wall of the box body 1 is provided with a waste heat recovery component 2. The placing component 3 includes a fixing block 31, which is fixedly connected to the upper end of the surface of the box body 1, and the placing plate 34 is slidably connected to the bottom end of the inner wall of the box body 1. The inner wall of the bottom end of the box body 1 is provided with two groups of guide grooves, so that the placing plate 34 can only slide back and forth on the inner wall of the box body 1, and the placing plate 34 cannot be separated from the inner wall of the box body 1. There are two groups of fixing blocks 31, and a shielding door 4 is rotatably connected between the two groups of fixing blocks 31. The surface of the shielding door 4 is provided with a handle, which can be used to facilitate the opening of the shielding door 4 to place the material to be heated inside it.

[0026] Reference Figure 3-Figure 4The inner wall of the right fixing block 31 is elastically connected to the limiting block 36 by a limiting spring 35, and a limiting groove is provided at the rotation center of the right side of the shielding door 4, and the bottom end of the outer wall of the limiting block 36 is plugged into the inner wall of the limiting groove. The plugging between the two fixes the position of the shielding door 4 after it is rotated, expanded, and closed, so as to facilitate loading and unloading of the interior. One end of the limiting spring 35 is fixedly connected to the surface of the limiting block 36, and the other end of the limiting spring 35 is fixedly connected to the inner wall of the right fixing block 31. The function of the limiting spring 35 is to automatically reset the position after the limiting block 36 is pulled outward. The inner side wall of the shielding door 4 is slidably connected to two sets of sliders 32, and the inner wall of the shielding door 4 is provided with a sliding groove that fits the top of the slider 32, so that the shielding door 4 will drive the slider 32 to move on its inner wall when it is expanded. The cam 33 is connected to the top of the cam 33 and the bottom of the cam 33 is connected to the top of the cam 33, so that the cam 33 is connected to the cam 33 on both sides of the cam 33.

[0027] Reference Figure 5-Figure 6 The waste heat recovery component 2 includes a circulation pipe 21. The circulation pipe 21 is a prior art. The pipe body is a surround type. When the internal water circulates through the circulation pipe 21, the flow rate of the water can be slowed down, so that the waste heat inside the box 1 can be fully absorbed by the circulation pipe 21 and conducted to the internal circulating water. The circulation pipe 21 passes through and is fixedly connected to the inner wall of the top of the box 1. Another group of circulation pipes 21 passes through and is fixedly connected to the inner wall of the bottom end of the box 1. There are two groups of circulation pipes 21. A connecting pipe 22 is fixedly connected between the two groups of circulation pipes 21. One end of the upper and lower groups of circulation pipes 21 passes through the box 1 and is connected to the connecting pipe 22, so that the water can evenly absorb the waste heat from the upper and lower ends of the box 1. The outer wall of the right side of the connecting pipe 22 is fixedly connected to a connecting seat 23. The outside of the connecting seat 23 is provided with an installation port, which is convenient for installing an external water pipe on its surface.

[0028] Reference Figure 6The inner wall of the connecting seat 23 is penetrated and rotatably connected with a rotating ball 24. The surface of the rotating ball 24 is provided with a through hole, and a handle is provided on the top thereof. By rotating the handle, the rotating ball 24 can be rotated, so that the connecting seat 23 can be closed or opened, so as to facilitate the installation of a water pipe on its surface to allow water to pass through the upper and lower sets of flow pipes 21 for waste heat recovery. The top of the outer wall of the connecting seat 23 is fixedly connected with a connecting block 25. The inner wall of the connecting block 25 is elastically connected with an insert block 27 through a reset spring 26. The reset spring 2 One end of 6 is fixedly connected to the surface of the plug block 27, and the other end of the return spring 26 is fixedly connected to the left inner wall of the connecting block 25. The function of the return spring 26 is to automatically reset the position of the plug block 27 after it is pulled outward. The plug block 27 passes through and is slidably connected to the inner wall of the connecting block 25. The outer wall of the top of the rotating ball 24 is provided with two sets of empty grooves, and the bottom end of the outer wall of the plug block 27 is plugged into the inner wall of the empty groove. The plugging between the two fixes the position of the rotating ball 24 after it is rotated open and closed on the inner wall of the connecting seat 23.

[0029] Working principle: Before heating the material, pull the limit block 36 outward to separate it from the limit groove at the right rotation center of the shielding door 4, release the fixation of the shielding door 4, and open the shielding door 4 through the handle. During the expansion of the shielding door 4, the slider 32 slides to the right in the slide groove on the inner wall of the shielding door 4. The movement of the slider drives the hinged rod 33 to slide on the inner walls of the cavity on both sides of the box body 1. The hinged rod 33 pulls the placement plate 34 to slide forward in the guide groove on the inner wall of the box body 1 and slides out of the box body 1, placing the material to be heated on the placement plate 34. After placement is completed, close the shielding door 4, and the slider 32 will push the hinged rod 33 and the placement plate 34 to move on the inner wall of the box body 1. At this time, release the limit block 36 and it will be reinserted into the limit groove under the action of the limit spring 35 to fix the shielding door 4.

[0030] After the materials are placed, the box 1 is started to heat the materials inside. During the heating process, part of the heat generated inside the box 1 is conducted to the circulation pipe 21 at the bottom end of the box 1 through the multiple groups of through holes on the surface of the placement plate 34, and the other part is conducted to the circulation pipe 21 at the top end of the box 1 through the multiple groups of through holes at the top end of the box 1.

[0031] When recovering waste heat, pull the plug 27 outward to separate it from the empty groove on the outer wall of the top end of the rotating ball 24, release the fixation of the rotating ball 24, rotate the rotating ball 24 by the handle, so that the through hole on its surface is connected to the inside of the connecting seat 23, open the connecting seat 23, and install the external water pipe on the mounting port of the connecting seat 23. Water enters the connecting pipe 22 through the connecting seat 23 and is then evenly distributed to the flow pipes 21 at the upper and lower ends of the box body 1. Since the flow pipe 21 is a surround type and the internal water flow speed is slowed down, it can fully absorb the waste heat inside the box body 1. The water after absorbing the waste heat then flows out through the connecting pipe 22 and the connecting seat 23 to realize waste heat recovery. After the waste heat recovery work is completed, rotate the rotating ball 24 in the opposite direction to close the connecting seat 23. Under the action of the reset spring 26, the plug 27 is reinserted into the empty groove on the outer wall of the top end of the rotating ball 24 to fix the position of the rotating ball 24.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
