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] See also Figures 1 to 4The utility model provides a technical solution: a high-temperature pre-burned material cooling device, comprising a cooling box 1, a cooling assembly 200 is installed on the inner side of the cooling box 1, and a conveying assembly 300 is installed between the inner and outer sides of the cooling box 1; through the coordinated use of the cooling assembly 200 inside the cooling box 1 and the conveying assembly 300, the heat exchange of the cooling medium can be more fully and effectively utilized for cooling, so that the cooling medium can be fully utilized, thereby improving the efficiency and effect of the heat exchange, and at the same time, it can also improve the heat conduction efficiency to a certain extent, thereby further improving the heat exchange efficiency, so that the high-temperature material in the cooling device can be effectively and stably cooled, thereby greatly improving the practicality of the high-temperature pre-burned material cooling device.

[0026] In this embodiment, the cooling assembly 200 is a structure for cooling high-temperature materials during transportation.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the cooling assembly 200 includes two active rods 201 rotatably connected to the inner side of the cooling box 1 through bearings, a spiral heat pipe 202 fixed to the outside of the active rod 201, a plurality of heat dissipation fins 203 fixed to the outside of the active rod 201, a first connecting groove 204 opened at the left end of the active rod 201, two liquid inlet pipes 205 rotatably connected to the left side of the cooling box 1 through bearings, a second connecting groove 206 opened at the right end of the active rod 201, a liquid outlet pipe 207 rotatably connected to the right end of the spiral heat pipe 202 through bearings, and a heat-conducting tube 208 fixed to the outside of the active rod 201.

[0028] It should be noted that the outer side of the spiral heat pipe 202 is fixedly connected to the inner side of the corresponding heat-conducting tube 208, and the outer side of the heat-conducting fin 203 is fixedly connected to the inner side of the corresponding heat-conducting tube 208, so that the heat conduction efficiency between the inside and outside of the heat-conducting tube 208 can be further improved. The left end of the spiral heat pipe 202 passes through the outer side of the corresponding active rod 201 and extends to the inside of the first connecting groove 204. The outer side of the left end of the spiral heat pipe 202 is rotatably connected to the inner side of the corresponding liquid inlet pipe 205 through a bearing, so that the cooling medium inside the liquid inlet pipe 205 can normally enter the interior of the spiral heat pipe 202.

[0029] In addition, the centers of the left and right ends of the spiral heat pipe 202 are located on the same axis as the center of the corresponding active rod 201, so that the active rod 201 can drive the spiral heat pipe 202 to rotate normally and synchronously. The right end of the spiral heat pipe 202 passes through the outside of the corresponding active rod 201 and extends to the inside of the corresponding second connecting groove 206, and then extends to the outside through the right side of the second connecting groove 206, so that the cooling medium inside the spiral heat pipe 202 can normally enter the inside of the liquid outlet pipe 207, wherein the right end of the liquid outlet pipe 207 can be connected to the waste heat recovery equipment, thereby achieving the effect of heat recovery and utilization.

[0030] In this embodiment, the conveying assembly 300 is a structure for conveying high-temperature magnetic materials.

[0031] like Figure 1 、 Figure 3 and Figure 4 As shown, the conveying assembly 300 includes a spiral blade 301 fixed to the outside of the heat-conducting tube 208, a discharge pipe 302 fixed to the left side of the back of the cooling box 1, a feed pipe 303 fixed to the right side of the front of the cooling box 1, two gears 304 fixedly installed on the outside of the two active rods 201, four fixed rods 305 fixed to the back of the cooling box 1, a fixed plate 306 fixed between one end of the back of the four fixed rods 305, a servo motor 307 fixedly installed on the front of the fixed plate 306, a rotating rod 308 fixedly installed on the output shaft of the servo motor 307, two synchronous wheels 309 fixed respectively to the rotating rod 308 and the outside of the bottom active rod 201, and a synchronous belt 310 that is connected to the outside of the two synchronous wheels 309.

[0032] It should be noted that the two spiral blades 301 are symmetrically distributed, the opposite sides of the two gears 304 are meshed with each other, and the right end of the active rod 201 passes through the right side of the cooling box 1, so that the mutual meshing between the two gears 304 can respectively drive the two active rods 201 to rotate, and the rotation directions are opposite, and then the rotation directions of the two spiral blades 301 are opposite through the effect of opposite rotation directions. Because the two spiral blades 301 are symmetrically distributed, the pushing directions of the two can be the same, which is convenient for continuous conveying of materials. The feed pipe 303 is connected to the front conveying equipment, and the discharge pipe 302 is connected to the rear conveying equipment, so that materials can enter and discharge normally.

[0033] The working principle of the above embodiment is:

[0034] When cooling the ore after high temperature roasting of magnetic materials such as hematite, siderite, limonite, high iron bauxite, red mud, etc., the materials are poured into the interior of the cooling box 1 through the feed pipe 303, and the servo motor 307 is started to drive the rotating rod 308 to rotate, and the corresponding active rod 201 is driven to rotate under the cooperation between the synchronous wheel 309 and the synchronous belt 310, so that the other gear 304 is also rotated under the mutual meshing action between the two gears 304 and the corresponding active rod 201 is rotated, so that both spiral blades 301 start to rotate. The material inside the cooling box 1 is moved and transported, and the cooling medium is transported to the inside of the spiral heat pipe 202 through the liquid inlet pipe 205. The spiral heat pipe 202 and the heat-conducting tube 208 perform heat conduction and heat exchange. Under the action of the heat dissipation fins 203, the heat conduction and heat exchange effect between the inside and outside of the heat-conducting tube 208 can be further improved, so that the heat of the internal transported material can be transferred through the spiral blades 301 and the outside of the heat-conducting tube 208, and the heat exchange effect is completed, which plays a cooling role. The transported material can be discharged through the discharge pipe 302.

[0035] Compared with the existing technology, the high-temperature pre-burned material cooling device, through the coordinated use of the cooling component 200 inside the cooling box 1 and the conveying component 300, can more fully and effectively utilize the heat exchange of the cooling medium for cooling, so that the cooling medium can be fully utilized, thereby improving the efficiency and effect of heat exchange, and at the same time, it can also improve the thermal conductivity efficiency to a certain extent, thereby further improving the heat exchange efficiency, so that the high-temperature material in the cooling device can be effectively and stably cooled, thereby greatly improving the practicality of the high-temperature pre-burned material cooling device, and solving the problem that the internal cooling medium of the existing high-temperature material cooling equipment flows too fast during the cooling process, which is not conducive to the full utilization of the cooling medium.

The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field.
