Specific embodiments

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] The following is combined with Figure 1-8 to illustrate the specific embodiments of the present invention. An energy-saving and environment-friendly magnetic block sintering kiln furnace includes a kiln furnace body 1, the kiln furnace body 1 is composed of a combustion chamber 101 and a kiln furnace chamber 103, a guiding chamber 102 is arranged outside the kiln furnace chamber 103, and a plurality of electromagnets 108 are inclinedly arranged on the inner wall of the kiln furnace chamber 103,

[0032] Rotate the support 4. The rotating support 4 is arranged in the furnace chamber 103. A plurality of magnet supporting components 6 are arranged on the rotating support 4. Second through holes 401 are arranged on both the upper and lower sides of the rotating support 4. A blade group 5 is fixedly connected inside the rotating support 4.

[0033] After the heat enters the furnace chamber 103 through the guiding chamber 102, the device directly acts on the rotating support 4. At the same time, an electromagnet 108 arranged in the furnace chamber 103 (using the principle of same-sex repulsion with the magnets placed on the rotating support 4) is used to push it to rotate. Since the second through holes 401 and the blade group 5 are arranged on the rotating support 4, the rotation of the blade group 5 forms a negative pressure in the cavity of the rotating support 4, causing the heat above the rotating support 4 to flow through the second through holes 401 and transfer to the lower part of the rotating support 4 under the influence of pressure. Furthermore, the rotation of the blade group 5 will circulate the heat in the furnace chamber 103, making the heat distribution in the furnace chamber 103 more uniform, thereby improving the sintering effect of the device.

[0034] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8 , the guiding chamber 102 is connected to the combustion chamber 101 through a blower 9, the guiding chamber 102 is connected to the furnace chamber 103 through a conduit 104, a furnace upper cover 2 is arranged on the top of the furnace chamber 103, and the extending direction of the conduit 104 forms a 45-degree angle with the connection line to the rotation center of the rotating support 4; in a specific embodiment of the present invention, referring again to Figure 1-8 , the combustion chamber 101 is connected to the outside through an air inlet 106. A filter screen is arranged on the air inlet 106. A gas furnace 3 is installed in the combustion chamber 101. The combustion chamber 101 is connected to the furnace chamber 103 through a first through hole 105; a preheating pipe 8 is arranged in the combustion chamber 101. The lower end of the preheating pipe 8 is connected to the air inlet 106, the upper end of the preheating pipe 8 is connected to the air guiding chamber, and the preheating pipe 8 is arranged outside the gas furnace 3.

[0035] The heat of the gas furnace 3 is transferred to the inside of the furnace chamber 103 by a baffle (the baffle is made of a high-temperature resistant material) arranged between the combustion chamber 101 and the furnace chamber 103. At the same time, the remaining heat of the gas furnace 3 will heat the preheating pipe 8. Under the action of the blower 9, the air in the preheating pipe 8 is transported from the guiding chamber 102 to the inside of the furnace chamber 103. The furnace chamber 103 sinter the magnets at the bottom and side at the same time. Compared with the transmission device, such a setting can separate the magnets from the fire source while maintaining the original sintering effect, avoiding the dust generated by combustion from falling on the magnets and affecting the smoothness of the magnet surface;

[0036] Meanwhile, by setting the conduit 104 in an inclined direction, in the case of hot air flow, it acts on the rotating bracket 4 to drive the rotating bracket 4 to rotate. With the cooperation of the provided first through hole 105, hot air can enter the combustion chamber 101 to provide oxygen for the combustion of the gas furnace 3. Since the hot air increases the reaction temperature and also increases the diffusion of oxygen, the combustion efficiency of the device is improved.

[0037] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8 , the preheating pipeline 8 is spirally connected between the air inlet 106 and the guiding chamber 102, and the blower 9 is arranged on the preheating pipeline 8.

[0038] During use, the blower 9 is driven to convey the heated air in the preheating pipeline 8 to the kiln chamber 103 through the guiding chamber 102, and the hot air flow is used to sinter the magnetic blocks.

[0039] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8 , a boss 402 is arranged on the periphery of the rotating bracket 4, and an external gear ring 403 is arranged at the connection between the rotating bracket 4 and the magnetic block supporting component 6, and the external gear ring 403 is in transmission connection with the magnetic block supporting component 6.

[0040] Under the action of the hot air, the rotating bracket 4 is driven to rotate, and the setting of the boss 402 can increase the effect of the hot air acting on the rotating bracket 4.

[0041] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8 , a transmission component 7 is connected to the side of each magnetic block supporting component 6, the transmission component 7 is rotatably connected to the rotating bracket 4, and the lower side of the transmission component 7 extends to the bottom of the kiln chamber 103 and is in transmission connection with an internal gear ring 107 fixedly connected in the kiln chamber 103.

[0042] During the rotation of the rotating bracket 4, it will drive the transmission component 7 to rotate in meshing with the internal gear ring 107, thereby driving the magnetic block supporting component 6 to rotate, to change the positions of the magnetic blocks on both sides of the magnetic block supporting component 6, so that the magnetic blocks on both sides of the magnetic block supporting component 6 alternately approach one side of the conduit 104, making the heating more uniform.

[0043] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8, the transmission assembly 7 includes a transmission rod 702 rotatably connected to the rotating bracket 4. A first helical gear 701 is fixedly connected to the upper side of the transmission rod 702. The first helical gear 701 is meshed and connected with the magnet supporting assembly 6. A first transmission gear 703 is fixedly connected to the bottom of the transmission rod 702. The first transmission gear 703 is meshed and connected with the internal gear ring 107.

[0044] During the rotation of the rotating bracket 4, the first transmission gear 703 is meshed with the internal gear ring 107. The transmission rod 704 drives the first helical gear 701 to rotate, and then, by using its meshing with the magnet supporting assembly 6, the positions of the two side magnets on the magnet supporting assembly 6 are changed.

[0045] Preferably, in a specific embodiment of the present invention, with reference again to Figure 1-8 , the magnet supporting assembly 6 includes a supporting bracket 601 rotatably connected to the rotating bracket 4. Supporting molds 603 are rotatably connected to both sides of the supporting bracket 601. A second transmission gear 604 is fixedly connected to one side of each supporting mold 603. The second transmission gear 604 is meshed and connected with the external gear ring 403. A second helical gear 602 is fixedly connected to one side of the supporting bracket 601. The second helical gear 602 is meshed and connected with the first helical gear 701.

[0046] When the first helical gear 701 meshes with the second helical gear 602, it drives the supporting bracket 601 to rotate, changing the positions of the magnets arranged on both sides of the supporting bracket 601. During the rotation of the supporting bracket 601, the second transmission gear 604 is meshed with the external gear ring 403. Such a setting can always keep the plane where the supporting mold 603 is located parallel to the upper surface of the rotating bracket 4 during the rotation of the supporting bracket 601. Such a setting can adjust the positions of the two side magnets without changing the two poles of the magnet.

[0047] The working principle of the device of an energy-saving and environment-friendly magnet sintering furnace of the present invention is as follows:

[0048] The device utilizes the heat to enter the furnace chamber 103 through the guiding chamber 102 and directly act on the rotating bracket 4. At the same time, the electromagnet 108 arranged in the furnace chamber 103 (using the principle of same-sex repulsion with the magnet placed on the rotating bracket 4) is used to push it to rotate. Since the second through hole 401 and the blade group 5 are arranged on the rotating bracket 4, the rotation of the blade group 5 forms a negative pressure in the cavity of the rotating bracket 4, causing the heat above the rotating bracket 4 to flow through the second through hole 401 and transfer to the lower part of the rotating bracket 4 under the influence of the pressure. Furthermore, the rotation of the blade group 5 will circulate the heat in the furnace chamber 103, making the heat distribution in the furnace chamber 103 more uniform, thereby improving the sintering effect of the device;

[0049] During the rotation of the rotating bracket 4, the rotation of the meshing between the transmission assembly 7 and the internal gear ring 107 will be driven, thereby driving the magnetic block supporting assembly 6 to rotate, so as to change the positions of the magnetic blocks on both sides of the magnetic block supporting assembly 6, so that the magnetic blocks on both sides of the magnetic block supporting assembly 6 alternately approach one side of the conduit 104, making the heating more uniform.

[0050] The present invention is not limited to the above optional embodiments, and any person can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
