[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0036] Please also read Figures 1 to 6, the connection device for the hot slag tank provided by the utility model is now described. The connection device for the hot slag tank comprises an elastic connection tube 1, an upper connection plate 2 and a lower connection plate 3. The elastic connection tube 1 has a water passage 11 which passes through from top to bottom, and the two ends of the water passage 11 are respectively connected with the bottom of the hot slag tank and the opening of the water supply and drainage pipe; the upper connection plate 2 is sleeved on the outer periphery of the top of the connection tube 1, and the plate surface of the upper connection plate 2 is perpendicular to the long axis of the connection tube 1, and the upper connection plate 2 is in contact with the hot slag tank; the lower connection plate 3 is sleeved on the outer periphery of the bottom of the connection tube 1, and the plate surface of the lower connection plate 3 is perpendicular to the long axis of the connection tube 1, and the lower connection plate 3 is connected to the water supply and drainage pipe.

[0037] It should be noted that the long axis of the connecting tube 1 is parallel to the vertical direction, forming a structure in which the hot and stuffy tank, the connecting tube 1 and the water supply and drainage pipes are connected in sequence from top to bottom.

[0038] It should be noted that the length of the connecting tube 1 is greater than the distance between the bottom of the heat-stifling tank and the water supply and drainage pipe, so that the connecting tube 1 can be deformed in the up and down directions after being installed between the heat-stifling tank and the water supply and drainage pipe, and the connecting tube 1 provides thrust in the reverse direction, provides pre-tightening force for the upper connecting plate 2 to move toward the heat-stifling tank, and provides pre-tightening force for the lower connecting plate 3 to move toward the water supply and drainage pipe, so as to achieve the effect of sealing the gap between the upper connecting plate 2 and the heat-stifling tank, and the gap between the lower connecting plate 3 and the water supply and drainage pipe, thereby improving the sealing stability of the overall structure.

[0039] Compared with the prior art, the connecting device for the hot stuffy slag pot provided in the present embodiment is arranged between the hot stuffy pot and the water supply and drainage pipe. A water passage 11 is arranged in the connecting tube 1, which can connect the hot stuffy pot and the water supply and drainage pipe to ensure the normal flow of water. The upper connecting plate 2 abuts against the bottom of the hot stuffy pot, and the lower connecting plate 3 is connected to the water supply and drainage pipe to improve the connection stability. The connecting tube 1 is elastic. After the connecting tube 1 is placed between the bottom of the hot stuffy pot and the water supply and drainage pipe, it is squeezed and deformed. The connecting tube 1 applies a thrust in the reverse direction to improve the fitting effect between the upper connecting plate 2 and the hot stuffy pot, and the sealing effect between the lower connecting plate 3 and the water supply and drainage pipe, thereby improving the sealing performance, preventing water from overflowing from between the hot stuffy pot and the water supply and drainage pipe, reducing the maintenance cost, and improving the water transportation stability.

[0040] In some embodiments, see Figure 2The connecting tube 1 includes an upper section, a middle section and a lower section which are connected in sequence from top to bottom. Both the upper section and the lower section are cylindrical components. The upper connecting plate sleeve 2 is arranged on the outer periphery of the upper section, and the lower connecting plate 3 is sleeved on the outer periphery of the lower section. The middle section is a spherical structure, and the water passage 11 has a spherical water passage space. The spherical design allows water to be buffered when passing through the water passage 11; when the connecting tube 1 is squeezed and deformed, the deformation direction of the connecting tube 1 can be parallel to the up and down directions, and there will be no tilting deformation. The spherical structure has a uniform structural distribution and a high degree of stability. It will deform regularly in the vertical direction after being subjected to pressure from the top and bottom, ensuring that after the connecting tube 1 is deformed, the plate surfaces of the upper connecting plate 2 and the lower connecting plate 3 are always parallel to each other and perpendicular to the vertical direction respectively.

[0041] In some embodiments, see Figure 1 The connection device for the hot slag tank also includes an elastic member 4, and the two ends of the elastic member 4 are respectively connected to the upper connecting plate 2 and the lower connecting plate 3. The elastic member 4 is configured with a pre-tightening force that pushes the upper connecting plate 2 and the lower connecting plate 3 away from each other. The elastic member 4 can assist the connecting tube 1 in pushing the upper connecting plate 2 and the lower connecting plate 3, thereby improving the sealing effect of the device. At the same time, the elastic member 4 has the shortest compression distance, which can prevent the connecting tube 1 from being over-extruded, thereby improving the protection effect of the connecting tube 1. The elastic member 4 and the connecting tube 1 are deformed at the same time, thereby sharing the force borne by the connecting tube 1, thereby preventing the connecting tube 1 from being subjected to excessive force and causing non-elastic deformation, thereby extending the service life of the connecting tube 1.

[0042] Optionally, the elastic member 4 is a coil spring, which has a certain strength, good elasticity, and good deformation continuity, and can meet the requirements of the elastic member 4. Of course, the elastic member 4 can also be other elastic components, such as a tower spring, as long as it can be elastically deformed and automatically restored, and they are not listed here one by one.

[0043] In some embodiments, see Figure 1 There are multiple elastic members 4, and multiple elastic members 4 are arranged around the outer circumference of the connecting tube 1. Multiple elastic members 4 are arranged around the connecting tube 1, which can provide uniform pre-tightening force around the connecting tube 1, ensure that the upper connecting plate 2 and the lower connecting plate 3 are evenly stressed, so that the plate surface of the upper connecting plate 2 and the plate surface of the lower connecting plate 3 are always perpendicular to the vertical direction.

[0044] In some embodiments, see Figure 6 The elastic member 4 is sleeved on the outer circumference of the connecting tube 1. As another embodiment of the arrangement of the elastic member 4, the elastic member 4 is sleeved on the outer circumference of the connecting tube 1, which can limit the maximum deformation of the connecting tube 1 and avoid excessive deformation of the connecting tube 1.

[0045] In some embodiments, see Figure 1 and Figure 5The upper surface of the upper connecting plate 2 is provided with an annular groove 211; the connection device for the hot slag pot also includes a sealing ring 5, which is embedded in the groove 211 and the top of which protrudes from the upper connecting plate 2. The sealing ring 5 is used to seal the gap between the upper connecting plate 2 and the bottom of the hot slag pot. The groove 211 can fix the sealing ring 5 to prevent the sealing ring 5 from coming out of the gap between the hot slag pot and the upper connecting plate 2 when squeezed. The sealing ring 5 can further improve the sealing performance between the hot slag pot and the upper connecting plate 2.

[0046] In a specific implementation, the cross-sectional area of ​​the sealing ring 5 gradually decreases from the outside to the inside along the direction close to the sealing ring 5 .

[0047] In a specific implementation, an annular groove is provided in the middle of the outer circumference of the sealing ring 5 . When the sealing ring 5 is squeezed, it can be deformed at the annular groove, ensuring that the sealing ring 5 is still located in the groove 211 after deformation.

[0048] In some embodiments, see Figure 2 and Figure 5 The outer circumference of the upper section protrudes outward to form a first clamping protrusion 12. The upper surface of the upper connecting plate 2 is provided with a first clamping groove 212 corresponding to the first clamping protrusion 12. The first clamping groove 212 and the first clamping protrusion 12 are clamped together to limit the displacement of the upper connecting plate 2 in the vertical direction. The provision of the first clamping groove 212 and the first clamping protrusion 12 improves the connection strength between the connecting tube 1 and the upper connecting plate 2. The connecting tube 1 is a spherical tube, so that the upper connecting plate 2 is clamped by the first clamping protrusion 12 and the outer circumference of the connecting tube 1, thereby improving the structural stability of the upper connecting plate 2 and the connecting tube 1.

[0049] In some embodiments, see Figure 2 and Figure 5 The outer circumference of the lower section protrudes outward to form a second clamping protrusion 13. The lower surface of the lower connecting plate 3 is provided with a second clamping groove 31 corresponding to the second clamping protrusion 13. The second clamping groove 31 and the second clamping protrusion 13 are clamped and matched to limit the displacement of the lower connecting plate 3 in the vertical direction. The second clamping groove 31 and the second clamping protrusion 13 are provided to improve the connection strength between the connecting tube 1 and the lower connecting plate 3. The connecting tube 1 is a spherical tube, so that the lower connecting plate 3 is clamped by the second clamping protrusion 13 and the outer circumference of the connecting tube 1, which improves the structural stability of the lower connecting plate 3 and the connecting tube 1.

[0050] In some embodiments, see Figure 5The upper connecting plate 2 includes an upper ring plate 21, a lower ring plate 23 and a transition ring 22. The upper and lower ends of the transition ring 22 are respectively connected to the upper ring plate 21 and the lower ring plate 23. The upper ring plate 21 abuts against the slag pot, and the lower surface of the lower ring plate 23 is connected to the elastic member 4. The upper ring plate 21 and the lower ring plate 23 are arranged with clear division of labor. The upper ring plate 21 abuts against the hot slag pot, and the lower ring plate 23 is connected to the elastic member to shorten the length of the elastic member 23, reduce the number of irregular deformations of the elastic member 23 during extrusion due to excessive length, and improve the stability of the elastic member 23 in use.

[0051] In some embodiments, see Figure 1 and Figure 2 A first positioning protrusion 231 is provided on the lower surface of the lower ring plate 23, and a second positioning protrusion 32 is provided on the upper surface of the lower connecting plate 3 corresponding to the first positioning protrusion 231. The two ends of the elastic member 4 are respectively sleeved on the first positioning protrusion 231 and the second positioning protrusion 32. The long axes of the first positioning protrusion 231 and the second positioning protrusion 32 are respectively parallel to the long axis of the elastic member 23. The elastic member 23 is sleeved on the outer periphery of the first positioning protrusion 231 and the second positioning protrusion 32, so that the elastic member 23 can be extended and retracted along the long axes of the first positioning protrusion 231 and the second positioning protrusion 32, ensuring that the extension and retraction direction of the elastic member 23 is always parallel to the vertical direction.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
