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.

[0043] Example 1

[0044] See Figure 1-4 , a reaction feeding heating furnace that is easy to maintain, includes a main body component 1, the main body component 1 includes: a bottom plate 11, a heating furnace 12 is provided on the top of which; a discharge port 13, which is connected to the right side wall of the heating furnace 12; a furnace cover 14, which is movably connected to the top of the heating furnace 12; a lifting component 2 is provided on the bottom plate 11 and the discharge port 13, and the lifting component 2 includes: a slide bar 21, which is symmetrically arranged on the top of the bottom plate 11; a cross frame 22, which is arranged on the top of the slide bar 21; a slider 23, which is symmetrical and slidably connected to the outside of the slide bar 21; a plate body 24, which is fixedly connected between the sliders 23; a hydraulic rod 25, which is arranged on the cross frame 22; a fixing mechanism 26 is arranged on the plate body 24 and the hydraulic rod 25; a second motor 27, which is arranged on the top of the discharge port 13, and the output shaft of the second motor 27 passes through and extends to the inside of the heating furnace 12; a stirring rod 271, which is circumferentially symmetrically arranged on the outside of the output shaft of the second motor 27. The fixing mechanism 26 includes: a bevel gear 261 rotatably connected to the top of the plate 24; a first motor 262 fixedly connected to the output shaft at the bottom of the hydraulic rod 25, the output shaft of the first motor 262 being fixedly connected to the bevel gear 261; a bracket 263 fixedly connected to the top of the plate 24; a screw rod 264 rotatably connected to the bracket 263; a bevel gear 265 fixedly connected to the end of the screw rod 264 near the first motor 262 and meshing with the bevel gear 261; a threaded plate 266 threadedly connected to the screw rod 264, the bottom end of the threaded plate 266 passing through and extending to the bottom of the plate 24, the plate 24 having a through slot for the threaded plate 266 to move; and a support block 267 fixedly connected to the bottom of the threaded plate 266. In addition to the bevel gear 261 and the first motor 262, the fixing mechanism 26 includes multiple groups of at least two groups symmetrically arranged around the same circumference.

[0045] When in use, the staff first lifts the furnace cover 14 upwards through the lifting assembly 2 to facilitate the placement of the reaction heated raw materials into the heating furnace 12: start the hydraulic rod 25, the hydraulic rod 25 extends downward, and the plate body 24 connected to the hydraulic rod 25 through the first motor 262 drives the slider 23 to slide downward on the slide rod 21. When the plate body 24 contacts the top of the second motor 27, the power of the hydraulic rod 25 is turned off, and the fixing mechanism 26 links the multiple sets of threaded plates 266 to drive the support block 267 to move toward the center of the plate body 24: start the first motor 262, the first motor 262 drives the bevel gear 261 to rotate, and the multiple bevel gears 265 meshing with the bevel gear 261 rotate at the same time, and the bevel gear 265 drives the screw rod 264 to rotate, and the threaded plate 266 threadedly connected to the screw rod 264 66 moves toward the middle of the plate 24. When the support block 267 contacts the outer wall of the heating furnace 12, the threaded plate 266 cannot move further. The first motor 262 is turned off, and the hydraulic rod 25 is controlled to drive the plate 24 to move upward. The support block 267 will drive the furnace cover 14 to separate from the heating furnace 12. At this time, the raw materials can be put into the heating furnace 12. The hydraulic rod 25 is controlled to make the furnace cover 14 return to the top of the heating furnace 12. The first motor 262 is controlled to reverse so that the threaded plate 266 drives the support block 267 away from each other. The hydraulic rod 25 drives the plate 24 back to the top. At this time, the heating furnace 12 heats the raw materials. The second motor 27 is started, and the stirring rod 271 stirs the raw materials in the heating furnace 12 to facilitate uniform heating of the raw materials. The raw materials that have completed the reaction are discharged from the discharge port 13. The furnace cover 14 is driven to separate from the heating furnace 12, which is convenient for the staff to observe and maintain the internal situation of the heating furnace 12. The threaded plates 266 and support blocks 267 in the fixing mechanism 26 support the furnace cover 14. There are multiple groups of them, which increase the stability of the furnace cover 14 when it is lifted and dropped, and facilitate the furnace cover 14 to return to the top of the heating furnace 12 to keep the heating furnace 12 warm.

[0046] Example 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See Figure 1-4 The bottom surface of the heating furnace 12 has an inclined surface. The output shaft of the second motor 27 is symmetrically and fixedly connected to a scraper 272, which is slidably connected to the inner wall of the heating furnace 12. A protective frame is provided on the top of the second motor 27.

[0049] The inclined surface inside the heating furnace 12 speeds up the flow of raw materials from the discharge port 13, reduces the residual raw materials in the heating furnace 12, and facilitates cleaning by the staff. When the second motor 27 drives the stirring rod 271 to stir, the scraper 272 rotates along with the stirring rod 271. The scraper 272 scrapes the raw materials on the inner wall of the heating furnace 12 during rotation to prevent the raw materials from adhering to the inner wall of the heating furnace 12 and affecting the normal heating of other raw materials. The protective frame on the second motor 27 limits the position of the plate body 24 to prevent the plate body 24 from directly contacting the second motor 27 and affecting the normal use of the second motor 27.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
