Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] Below is the attached figure Figures 1 to 4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0030] like Figure 1-4 As shown, a liquid cooling mechanism for cooling a kiln includes a kiln cooling section 1, a first cooling assembly 3, and a second cooling assembly 4. The first cooling assembly 3 and the second cooling assembly 4 are installed on the outside of the kiln cooling section 1, and the cooling ends of the first cooling assembly 3 and the second cooling assembly 4 extend into the interior of the kiln cooling section 1.

[0031] A conveying device 2 is provided inside the kiln cooling section 1, and the first cooling assembly 3 and the second cooling assembly 4 are arranged in sequence along the conveying direction of the conveying device 2;

[0032] A liquid inlet pipeline 5 and a liquid outlet pipeline 6 are respectively provided on two opposite outer sides of the kiln cooling section 1. The liquid inlet pipeline 5 is respectively connected to the liquid inlet ends of the first cooling component 3 and the second cooling component 4, and the liquid outlet pipeline 6 is respectively connected to the liquid outlet ends of the first cooling component 3 and the second cooling component 4.

[0033] This solution cools the interior of the kiln cooling section 1 by setting up the first cooling component 3 and the second cooling component 4, which can reduce the heat of the kiln cooling section 1 and make the temperature of the kiln cooling section 1 lower. There is no need to design the kiln cooling section 1 to be longer to achieve a good cooling effect, so that the fired material can achieve a good cooling effect after passing through the kiln cooling section 1.

[0034] like Figure 2 As shown, the liquid inlet pipeline 5 includes a liquid inlet main pipe 51, and the liquid inlet main pipe 51 is connected to two first liquid inlet branches 52, each first liquid inlet branch 52 is respectively connected to a second liquid inlet branch 53, and the liquid inlet ends of the two first cooling components 3 and the second cooling components 4 are respectively connected to the corresponding second liquid inlet branches 53.

[0035] Specifically, the coolant is transported to the two first liquid inlet branches 52 through the liquid inlet main pipe 51 , and the coolant is supplied to the two first cooling components 3 and the second cooling component 4 respectively through the two first liquid inlet branches 52 .

[0036] like Figure 2 As shown, the first cooling assembly 3 includes a plurality of first connecting pipes 31 and second connecting pipes 32;

[0037] The two ends of each first connecting pipe 31 respectively penetrate the two opposite inner side walls of the kiln cooling section 1 and extend to the outside to be connected to a first liquid inlet pipe 33 and a first liquid outlet pipe 34, several of the first liquid inlet pipes 33 are connected to the second liquid inlet branch pipe 53, several of the first liquid outlet pipes 34 are connected to the first manifold 35, the first manifold 35 is connected to the second liquid outlet pipe 36, and the second liquid outlet pipe 36 is connected to the liquid outlet pipeline 6;

[0038] Both ends of each second connecting pipe 32 pass through the two opposite inner walls of the kiln cooling section 1 and extend to the outside to be connected with a second liquid inlet pipe 37 and a third liquid outlet pipe 38 respectively. Several second liquid inlet pipes 37 and third liquid outlet pipes 38 are connected with the second liquid inlet branch pipe 53 and the liquid outlet pipeline 6 respectively.

[0039] Specifically, the coolant flows into the first liquid inlet pipe 33 and the second liquid inlet pipe 37 through the second liquid inlet pipe 53, and then flows into the first liquid outlet pipe 34 and the third liquid outlet pipe 38 through the first liquid inlet pipe 33 and the second liquid inlet pipe 37 respectively. Then, the coolant in the first liquid outlet pipe 34 converges to the first confluence pipe 35 and then flows into the liquid outlet pipe 6 through the second liquid outlet pipe 36 for discharge, and the coolant in the third liquid outlet pipe 38 flows into the liquid outlet pipe 6 for discharge.

[0040] like Figure 1-2 As shown, several first connecting tubes 31 and second connecting tubes 32 are respectively located on the upper and lower sides of the conveying device 2, several first connecting tubes 31 and second connecting tubes 32 are respectively arranged parallel to the conveying device 2, several first connecting tubes 31 are arranged at equal intervals, and several second connecting tubes 32 are arranged at equal intervals.

[0041] Specifically, several first connecting tubes 31 and second connecting tubes 32 are respectively located on the upper and lower sides of the conveying device 2, and can cool the upper and lower sides of the conveying device 2. The first connecting tube 31 can directly cool the upper surface of the fired material, and the second connecting tube 32 can cool the lower surface of the fired material and the conveying device 2 itself, effectively avoiding heat accumulation and improving cooling efficiency. It can also cool the fired material evenly, reduce the temperature gradient difference caused by cooling in a single direction, and thus avoid deformation or quality problems of the fired material due to uneven cooling.

[0042] like Figure 2 As shown, the distance between the first connecting pipe 31 and the conveying device 2 is greater than the distance between the second connecting pipe 32 and the conveying device 2 .

[0043] Specifically, since the fired material is transported above the transport device 2 , the distance between the first connecting pipe 31 and the transport device 2 needs to be greater than the distance between the second connecting pipe 32 and the transport device 2 .

[0044] like Figure 2 As shown, the second cooling assembly 4 includes a plurality of third connecting pipes 41, a second manifold 44 and a third manifold 45;

[0045] Both ends of each of the third connecting pipes 41 respectively penetrate the two opposite inner walls of the kiln cooling section 1 and extend to the outside to be connected with a third liquid inlet pipe 42 and a fourth liquid outlet pipe 43 respectively. Several of the third liquid inlet pipes 42 and the fourth liquid outlet pipes 43 are respectively connected with the second manifold 44 and the third manifold 45, and the second manifold 44 and the third manifold 45 are respectively connected with the second liquid inlet branch pipe 53 and the liquid outlet pipeline 6.

[0046] Specifically, the coolant flows into the second manifold 44 through the second liquid inlet branch 53, then flows to several third liquid inlet pipes 42, and flows into the corresponding third connecting pipes 41 through several third liquid inlet pipes 42, and then flows into the fourth liquid outlet pipe 43 through the third connecting pipe 41, and converges to the third manifold 45 through the fourth liquid outlet pipe 43, and finally flows into the liquid outlet pipeline 6 through the third manifold 45 for discharge.

[0047] like Figure 2 As shown, the plurality of third communicating tubes 41 are arranged in sequence from top to bottom and are arranged at equal intervals, and the intervals between the plurality of third communicating tubes 41 and adjacent fire retaining walls are equal.

[0048] Specifically, the kiln cooling section 1 is cooled by a plurality of third connecting pipes 41 arranged in sequence from top to bottom and at equal intervals. Compared with the first cooling component 3, the second cooling component 4 can absorb more heat through the additional third connecting pipes 41, so that the second cooling component 4 has a better cooling effect than the first cooling component 3, and can better reduce the temperature of the kiln cooling section 1 to meet the cooling requirements of the fired material.

[0049] It is worth noting that the first cooling component 3 and the second cooling component 4 are arranged in sequence along the conveying direction of the conveying device 2. Therefore, the kiln cooling section 1 where the first cooling component 3 is located is closer to the kiln firing section, and the kiln firing section transfers more heat to the kiln cooling section 1 where the first cooling component 3 is located. If several third connecting pipes 41 are also added to the first cooling component 3, the cooling cost will increase and the cooling effect will be poor. Therefore, adding several third connecting pipes 41 at a position farther away from the kiln firing section will have a better cooling effect.

[0050] like Figure 2As shown, a plurality of the first liquid inlet pipes 33 , the first liquid outlet pipe 34 , the second liquid inlet pipe 37 , the third liquid outlet pipe 38 , the third liquid inlet pipe 42 , the fourth liquid outlet pipe 43 and the two first liquid inlet branches 52 are respectively provided with control valves.

[0051] Specifically, the control valves provided can facilitate the control and maintenance of the pipeline.

[0052] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
