[0032] 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 described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. Example

[0033] Reference Figure 1-7, the utility model provides an embodiment: a waste heat recovery and utilization device that is easy to install, including a bellows 1 and a mounting seat 3, a No. 3 pipe 18 is fixedly arranged at the center of one side of the bellows 1, a No. 1 rotating member 19 is fixedly sleeved on one side of the outer wall of the No. 3 pipe 18, a ventilation duct 2 is fixedly arranged at the center of both front and rear end surfaces of the outer wall of the bellows 1, a clamping block 8 is fixedly arranged at the center of one side of the two ventilation ducts 2, and a clamping box 9 is fixedly arranged at the center of the other side of the two ventilation ducts 2, and the clamping box 9 can cooperate with the clamping block 8 to assemble multiple devices, so as to extend the distance of the ventilation ducts 2 to facilitate the improvement of the waste heat recovery efficiency for a longer burning zone;

[0034] A gear 26 is rotatably arranged at the center of the bottom end face of the inner wall of the snap-in box 9. The gear 26 can limit its own rotation angle through a sliding block 30, and cooperate with a plurality of tooth grooves 10 to fix the position of the snap-in block 8. A sliding groove 28 is provided at the center of the lower end face of the outer wall of the snap-in box 9 near the rear end, and an embedding groove 27 is provided at the upper end of the inner wall of the sliding groove 28 near one side. A sliding block 30 is slidably arranged in the sliding groove 28, and a rebound groove 32 is provided at the upper end face of the sliding block 30 near one side.

[0035] A fixing mechanism 31 is movably arranged in the rebound groove 32. The position of the sliding block 30 can be restricted by the design of the fixing mechanism 31, so that the sliding block 30 will not restrict the rotation angle of the gear 26 during the splicing process. The fixing mechanism 31 includes an insert block 3101, a rebound spring 3102 and a pull rod 3103. The center of the front and rear ends of the inner wall of the bellows 1 are embedded with mounting tubes 13, and fans 14 are rotatably arranged in the two mounting tubes 13. A No. 1 pipe 5 is fixedly arranged at the center of one side of the mounting seat 3, and a connecting pipe 6 is threadedly arranged near one side of the outer wall of the No. 1 pipe 5.

[0036] A primary filter plate 23 is fixedly provided on one side of the inner wall of the connecting pipe 6, which can filter large pieces of residue. A snap-in groove 21 is provided on the other side of the inner wall of the connecting pipe 6, and a secondary filter plate 22 is slidably snap-fitted in the snap-in groove 21 to filter fine dust. A No. 2 pipe 7 is threadedly sleeved in the snap-in groove 21, and a No. 2 rotating part 20 is fixedly sleeved on one side of the No. 2 pipe 7.

[0037] When in use, the mounting seat 3 is directly fixed to the firing zone of the tunnel kiln through the screw hole 4, and then the motor 16 fixed in the mounting tube 13 through the mounting box 15 and the mounting frame 17 is started, and the fan 14 is driven to rotate by the motor 16, and the hot air is blown into the preheating zone along the ventilation duct 2 through the fan 14 to increase the temperature of the preheating zone and reduce the loss of fuel on the preheating kiln body. During the blowing process, the hot air is blown into the connecting pipe 6 along the No. 1 pipe 5 from the firing zone, and the slag in the hot air is filtered between the No. 1 pipe 5 and the connecting pipe 6 through the primary filter plate 23, and the fine dust in the hot air is filtered when passing through the secondary filter plate 22, so as to prevent the wind blown into the preheating zone from coating the dust and slag on the firing blank during long-term use, affecting the cleanliness of the surface of the fired product;

[0038] When used for a long time, the primary filter plate 23 and the secondary filter plate 22 will be clogged with dust. At this time, hold the handle 12 and adjust the No. 2 rotating member 20 to one side through the clamping groove 24 and the clamping ring 25, and fix the No. 1 rotating member 19 through the No. 3 pipe 18, so that the No. 2 rotating member 20 drives the No. 2 pipe 7 to rotate and escape from the clamping groove 21, and when the No. 2 pipe 7 escapes from the clamping groove 21, the friction between the bellows 1 and the ground is reduced through the universal wheel 11, and then the connecting pipe 6 is rotated to one side to remove the connecting pipe 6 from the outer wall of the No. 1 pipe 5, and then the secondary filter plate 22 is taken out along the clamping groove 21, and the secondary filter plate 22 and the primary filter plate 23 are cleaned;

[0039] When the kiln body firing zone is long, the efficiency of waste heat recovery using a single ventilation duct 2 will slow down, resulting in heat loss. At this time, the two devices can be spliced ​​through the clamping block 8 and the clamping box 9, and the clamping block 8 is embedded in the clamping box 9, and the multiple tooth grooves 10 under the clamping block 8 are engaged with the gear 26, so that when the clamping block 8 moves in the clamping box 9, the gear 26 rotates synchronously with the movement of the clamping block 8. When the two ventilation ducts 2 are clamped, the pull rod 3103 is pulled downward to make the embedding block 3101 disengage from the embedding groove 27. At this time, the sliding block 30 is embedded between the two teeth on the gear 26 under the action of the extrusion spring 29. The rotation angle of the gear 26 is limited to achieve the effect of fixing the position of the clamping block 8 in the clamping box 9, thereby preventing the two ventilation ducts 2 from being disconnected during use.

[0040] Working principle: The slag and dust in the high-temperature air in the kiln are filtered through the primary filter plate 23 and the secondary filter plate 22 to prevent the dust from affecting the surface finish of the fired product, and the No. 1 rotating part 19 and the No. 2 rotating part 20 can cooperate with the No. 2 pipe 7 to realize the rapid installation and disassembly of the connecting pipe 6, which is convenient for cleaning the primary filter plate 23 and the secondary filter plate 22. At the same time, multiple devices can be connected through the clamping block 8 and the clamping box 9, which can extend the length of the ventilation duct 2 and avoid the problem of large amount of heat loss caused by slow ventilation efficiency of the single ventilation duct 2 due to the long firing zone.

[0041] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
