[0028] The utility model will be further explained in detail in combination with embodiments:

[0029] Embodiment 1

[0030] As Figures 1-3 Indicated, this embodiment provides a kind of burner heat accumulator fixing device, including two fixed frames 3, two fixed frames 3 are correspondingly set in the inner cavity of burner 2 in detachable mode and are arranged in parallel to heat accumulation layer, i.e., two fixed frames 3 are correspondingly vertically set in the inner cavity of burner 2, and, two fixed frames 3 are located at the side of heat accumulation layer close to the port of burner 2, and two fixed frames 3 can limit each heat accumulator 1 of heat accumulation layer in cooperation.

[0031] Specifically, fixed frame 3 includes two cross bars and a plurality of vertical rods between two cross bars, two cross bars are correspondingly set in the inner cavity of burner 2 and are arranged in parallel to heat accumulation layer, a plurality of vertical rods are evenly spaced along the length direction of cross bar, i.e., each vertical rod is evenly spaced on cross bar from left to right, and the upper and lower ends of vertical rod are connected with two cross bars respectively, to form grid limit structure, can effectively prevent heat accumulator in heat accumulation layer from displacement, avoid heat accumulator 1 loosening or edge falling due to high-temperature airflow impact, ensure that heat accumulation layer long-term stable operation, wherein, the number of vertical rod can be selected according to the overall width of heat accumulation layer.

[0032] In order to better limit the heat storage bodies in the heat storage layer, the spacing between the upper horizontal rod of the upper fixed frame 3 and the lower horizontal rod of the lower fixed frame 3 is matched with the height of the heat storage layer, that is, the spacing between the upper horizontal rod of the upper fixed frame 3 and the lower horizontal rod of the lower fixed frame 3 is slightly smaller than the height of the heat storage layer, so as to intercept and limit the uppermost row of heat storage bodies 1 and the lowermost row of heat storage bodies 1 in the heat storage layer. The spacing between the lower horizontal rod of the upper fixed frame 3 and the upper horizontal rod of the lower fixed frame 3 is smaller than the height of the heat storage body 1, so as to avoid that the gap between the two fixed frames 3 is smaller than the height of a single heat storage body 1. At the same time, the spacing between the vertical rods at the left and right ends of the fixed frame 3 is matched with the width of the heat storage layer, and the spacing between the adjacent vertical rods of the fixed frame 3 is smaller than the width of the heat storage body 1, so as to avoid missing the heat storage body 1.

[0033] Further, the two ends of the two horizontal rods of the fixed frame 3 are connected with the inner walls on the left and right sides of the burner 2 through the guide components 4, that is, each fixed frame 3 is equipped with two guide components 4 corresponding to the horizontal rods on the left and right sides, a total of four guide components 4, so as to match the left and right ends of the upper and lower horizontal rods of the fixed frame 3, and the guide components 4 are perpendicular to the horizontal rods of the fixed frame 3 in the horizontal direction, that is, the guide components 4 are arranged on the inner walls of the burner 2 parallel to the axial direction of the burner 2. At the same time, the two ends of the two horizontal rods of the fixed frame 3 and the corresponding guide components 4 are cooperatively provided with fasteners, that is, each fixed frame 3 is equipped with the same number of fasteners as the number of guide components 4.

[0034] In application, the two fixed frames 3 can be moved forward and backward relative to the heat storage layer through the guide components 4 on the left and right sides thereof, and positioned on the guide components 4 through the fasteners, so as to fix the two fixed frames 3 to the heat storage layer to limit the heat storage bodies 1 in the heat storage layer, effectively preventing the heat storage bodies 1 in the heat storage layer from being displaced. The position of the fixed frame 3 can be flexibly adjusted according to the position of the heat storage layer in the inner cavity of the burner 2, and the universality is stronger.

[0035] Specifically, the guide component 4 includes two guide plates 4-1, which are strip-shaped. The two guide plates 4-1 are vertically aligned on the inner wall of the burner 2 and are perpendicular to the horizontal bar of the fixing frame 3. One side of each guide plate 4-1 is connected to the inner wall of the burner 2, forming a guide groove 4-2 parallel to the axial direction of the burner 2 between the two guide plates 4-1. The guide groove 4-2 is adapted to the end of the horizontal bar of the fixing frame 3. The left and right ends of the two horizontal bars of the fixing frame 3 can be slidably inserted into the corresponding guide grooves 4-2 of the guide component 4, allowing for back-and-forth movement along the axial direction of the burner 2 within the inner cavity of the burner 2. Furthermore, the front ends of the two guide plates 4-1 of the guide component 4 extend to the heat storage layer, and their rear ends extend to the burner 2 port, allowing the two fixing frames 3 to move back and forth relative to the heat storage layer within the area between the burner 2 port and the heat storage layer within the inner cavity of the burner 2.

[0036] The fastener includes a groove 5, a screw 6, and a nut 7. The groove 5 is opened through the thickness direction of the upper guide plate 4-1 of the guide component 4 and extends to the front and rear ends of the guide plate 4-1. The upper end of the screw 6 is threaded with the nut 7, that is, the nut 7 is fitted on the upper end of the screw 6 and threadedly connected to it. The lower end of the screw 6 passes through the groove 5 of the upper guide plate 4-1 and is threadedly connected to the top end of one end of the crossbar of the fixing frame 3 that slides into the guide groove 4-2 of the guide component 4. That is, when one end of the crossbar of the fixing frame 3 slides into the guide groove 4-2 of the guide component 4, the lower end of the screw 6 passes through the groove 5 of the upper guide plate 4-1 and is threadedly connected to the top end of one end of the crossbar of the fixing frame 3 that is inserted into the guide groove 4-2. The upper end of the screw 6 above the groove 5 is threaded with the nut 7, wherein the diameter of the nut 7 is larger than the width of the groove 5.

[0037] When the fixed frame 3 moves back and forth relative to the heat storage layer through the guide grooves 4-2 of the guide components 4 on its left and right sides, the screw 6 on the crossbar that slides into the guide groove 4-2 also moves back and forth in the sliding groove 5 of the upper guide plate 4-1. When the fixed frame 3 moves to the heat storage layer, the crossbar of the fixed frame 3 that slides into the guide groove 4-2 can be positioned on the upper guide plate 4-1 of the guide component 4 by tightening the nut 7 at the upper end of the screw 6, thereby limiting the position of the fixed frame 3. The structure is simple and resistant to high temperature vibration. When the fixed frame 3 needs to be adjusted again, the nut 7 can be loosened.

[0038] Example 2

[0039] like Figure 4 and Figure 5 As shown, the burner heat storage body fixing device provided in this embodiment has the same structure as that in Embodiment 1, except for the fasteners and the connection methods between the other components. The difference is that:

[0040] The fastener comprises a plurality of clamping blocks 8 and a clamping seat 9, the plurality of clamping blocks 8 are evenly spaced along the length direction of the upper guide plate 4-1 of the guide component 4, the clamping seat 9 is arranged at the top of one end of the horizontal rod of the fixing frame 3 corresponding to the guide component 4 and is located at one side of the guide component 4, wherein one end of each clamping block 8 is hinged to the top of the upper guide plate 4-1 of the guide component 4 through a rotating shaft 10, and the other end is matched with the clamping seat 9.

[0041] Specifically, the rotating shaft 10 is arranged parallel to the length direction of the upper guide plate 4-1 of the guide component 4, and the front and rear ends of the rotating shaft 10 are connected to the top of the upper guide plate 4-1 of the guide component 4 through vertical supporting rods 11 respectively. The top of the clamping seat 9 is provided with a clamping groove matched with the clamping block 8, and the depth of the clamping groove is greater than the thickness of the clamping block 8.

[0042] When the fixing frame 3 moves to the heat storage layer through the guide grooves 4-2 of the guide components 4 on the left and right sides, the clamping block 8 hinged to the top of the upper guide plate 4-1 of the guide component 4 can be rotated around the rotating shaft 10, so that the free end of the clamping block 8 is embedded in the clamping seat 9 at the end of the horizontal rod of the corresponding fixing frame 3. Since the depth of the clamping groove of the clamping seat 9 is greater than the thickness of the clamping block 8, after embedding, the free end of the clamping block 8 abuts against the bottom wall of the clamping groove of the base 9, and the inner walls on both sides of the clamping groove of the base 9 constrain the clamping block 8 in the transverse direction, forming a constraint structure, resisting the forward and backward movement of the fixing frame 3, and limiting the fixing frame 3. When it is necessary to adjust the fixing frame 3 again, the clamping block 8 can be rotated in the opposite direction to be released from the clamping seat 9 at the end of the horizontal rod of the fixing frame 3. Compared with embodiment 1, the embodiment is more efficient and has stronger self-locking when adjusting and installing the fixing frame 3, and is especially suitable for frequent adjustment scenes and convenient operation.
