[0027] Preferably, the end of the high-temperature flue gas inlet channel 2 away from the first partition 103 is connected to the outlet of the high-temperature flue gas duct; the end of the high-temperature air outlet channel 3 away from the first partition 103 is connected to the inlet of the high-temperature air recovery duct; the side of the low-temperature flue gas outlet channel 4 away from the second partition 105 is connected to the inlet of the induced draft fan 5; and the side of the low-temperature air inlet channel 6 away from the second partition 105 is connected to the outlet of the blower 7.

[0029] For ease of explanation, the four pull rod assemblies 11 are divided into a first pull rod assembly, a second pull rod assembly, a third pull rod assembly, and a fourth pull rod assembly. It is worth noting that the vertical height of the lower baffle door 113 of the first and third pull rod assemblies from the bottom of the pull rod 111 is greater than that of the lower baffle door 113 of the second and fourth pull rod assemblies from the bottom of the pull rod 111.

At this time, the two pull rods 111 located on the same side of the front or rear cavity of the outer shell 1 can pass through the mounting through holes on the heat storage unit 12 and be movably connected to the heat storage unit 12, or they can not pass through the heat storage unit 12 and be located on the outside of the heat storage unit 12, depending on the size of the heat storage unit 12.

[0031] Of course, the heat storage assembly may also include four heat storage units 12, wherein the four heat storage units 12 are fixed side by side in pairs on the front and rear side walls of the intermediate baffle 10, and the pull rods 111 of each group of pull rod assemblies 11 vertically penetrate through the mounting through hole on a heat storage unit 12 and are movably connected to the corresponding heat storage unit 12, that is, each pull rod 111 can slide up and down in its corresponding through mounting through hole in the heat storage unit 12, such as Figure 7 As shown.

[0032] It is worth noting that the specific number of heat storage cells 12 is determined according to the actual needs and size design of the equipment. As long as they are an even number and symmetrically distributed on the front and rear side walls of the intermediate baffle 10, the number of heat storage cells 12 is not a further limitation on this utility model.

[0033] Preferably, the fixed base plate 9 is located directly below the connecting plate 106, and the bottom of the pull rods 111 of the four pull rod assemblies 11 passes through the connecting plate 106 and is fixed to the fixed base plate 9 by bolts or welding. The specific fixing method is not considered as a further limitation of this patent.

[0034] Preferably, the top of the electric push rod 8 is connected to the bottom of the connecting plate 106, and the push rod part at the bottom of the electric push rod 8 is connected to the fixed base plate 9; by controlling the extension or retraction of the electric push rod 8, the fixed base plate 9 and the pull rod 111 fixed on the fixed base plate 9 can be driven to rise or fall.

[0035] like Figure 3 As shown, the upper door perforated plate 102 and the lower door perforated plate 104 have the same structure, both having four centrally symmetrical door stop through holes 1021. It is worth noting that the upper baffle doors 112 of the four pull rod assemblies 11 correspond one-to-one with the positions of the four door stop through holes 1021 of the upper door perforated plate 102; the lower baffle doors 113 of the four pull rod assemblies 11 correspond one-to-one with the positions of the four door stop through holes 1021 of the lower door perforated plate 104.

[0036] More preferably, the inner diameter of the door stop through hole 1021 is smaller than the outer diameter of the upper baffle door 112 or the lower baffle door 113, so that the upper baffle door 112 or the lower baffle door 113 can effectively block the door stop through hole 1021.

[0037] like Figure 6 As shown, in order to prevent gas leakage during the lifting and lowering movement of the pull rod 111, a linear bearing 1111, a telescopic tube 1112, and a closed cylinder 1113 are sequentially sleeved on the surface of the pull rod 111 located between the connecting plate 106 and the fixed base plate 9 from top to bottom; wherein, one end of the telescopic tube 1112 near the connecting plate 106 is sleeved on the linear bearing 1111 used for limiting, and the other end is sleeved on the top of the closed cylinder 1113, and the bottom of the closed cylinder 1113 is fixedly connected to the fixed base plate 9.

[0038] More preferably, the inner wall of the outer shell 1 is also lined with a high-temperature resistant insulation material.

[0039] The specific workflow of the continuous heat generation device is as follows (where a complete heat storage and release cycle is defined as including the first half-cycle and the second half-cycle):

[0040] In the first half of the cycle: when the push rod of the electric push rod 8 is in the retracted state, it drives the fixed base plate 9 and the four pull rod assemblies 11 to rise, thereby driving the four upper baffle doors 112 and the four lower baffle doors 113 to move upward simultaneously. At this time, the upper baffle doors 112 and lower baffle doors 113 of the first and third pull rod assemblies are respectively located above the door stop through holes 1021 corresponding to the upper door hole plate 102 and the lower door hole plate 104. That is, the high temperature flue gas inlet channel 2 and the low temperature flue gas outlet channel 4 are in communication with the heat storage unit 12 in the rear cavity of the outer shell 1, and the high temperature air outlet channel 3 and the low temperature air inlet channel 6 are in communication with the heat storage unit 12 in the front cavity of the outer shell 1. Meanwhile, the upper baffle doors 112 and lower baffle doors 113 of the second and fourth pull rod assemblies abut against the bottom of the upper door hole plate 102 and the lower door hole plate 104, which just blocks their respective door stop through holes 1021.

[0041] At this time, the high-temperature flue gas flowing out of the high-temperature flue gas pipe enters the door stop through hole 1021 corresponding to the upper baffle door 112 of the first tie rod assembly through the high-temperature flue gas inlet channel 2, and then enters the heat storage unit 12 in the rear cavity of the outer shell 1. After releasing heat and cooling down, it enters the low-temperature flue gas outlet channel 4 through the door stop through hole 1021 corresponding to the lower baffle door 113 of the first tie rod assembly, and is finally drawn away by the induced draft fan 5. Meanwhile, the low-temperature air is introduced into the low-temperature air inlet channel 6 through the blower 7 and enters the door stop through hole 1021 corresponding to the lower baffle door 113 of the third tie rod assembly through the door stop through hole 1021, and then enters the heat storage unit 12 in the front cavity of the outer shell 1. After the low-temperature air is heated by the high-temperature heat storage unit, it enters the high-temperature air outlet channel 3 through the door stop through hole 1021 corresponding to the upper baffle door 112 of the third tie rod assembly, and finally enters the high-temperature air recovery pipe.

[0042] Second half cycle: When the push rod part of the electric push rod 8 is in the extended state, it drives the fixed base plate 9 and the four pull rod assemblies 11 to descend, thereby driving the four upper baffle doors 112 and the four lower baffle doors 113 to move downward at the same time. At this time, the upper baffle doors 112 and lower baffle doors 113 of the first pull rod assembly and the third pull rod assembly press on the top of the upper door hole plate 102 and the lower door hole plate 104 respectively, which covers the corresponding door stop through holes 1021, thereby completing the sealing. The upper baffle doors 112 and lower baffle doors 113 of the second pull rod assembly and the fourth pull rod assembly descend to below the corresponding door stop through holes 1021 of the upper door hole plate 102 and the lower door hole plate 104 respectively, that is, they are in communication with the high temperature flue gas inlet channel 2 and the low temperature flue gas outlet channel 4 and the heat storage unit 12 in the front cavity of the outer shell 1, and the high temperature air outlet channel 3 and the low temperature air inlet channel 6 and the heat storage unit 12 in the rear cavity of the outer shell 1.

[0043] At this time, the high-temperature flue gas flowing out of the high-temperature flue gas pipe enters the door stop through hole 1021 corresponding to the upper baffle door 112 of the second tie rod assembly through the high-temperature flue gas inlet channel 2, and then enters the heat storage unit 12 in the front cavity of the outer shell 1. After releasing heat and cooling down, it enters the low-temperature flue gas outlet channel 4 through the door stop through hole 1021 corresponding to the lower baffle door 113 of the second tie rod assembly, and is finally drawn away by the induced draft fan 5. The low-temperature air is introduced into the low-temperature air inlet channel 6 by the blower 7 and enters the door stop through hole 1021 corresponding to the lower baffle door 113 of the fourth tie rod assembly, and then enters the heat storage unit 12 in the rear cavity of the outer shell 1. After the low-temperature air is heated by the high-temperature heat storage unit 12, it enters the high-temperature air outlet channel 3 through the door stop through hole 1021 corresponding to the upper baffle door 112 of the fourth tie rod assembly, and finally enters the high-temperature air recovery pipe, thus completing a complete heat storage and heat release cycle. The continuous operation of the heat storage high-temperature air generator can be achieved by controlling the periodic extension and retraction of the electric push rod 8.

[0044] This utility model has a simple structure and reasonable design, and provides a device that does not require periodic alternation of high-temperature flue gas inlet and high-temperature air outlet. During use, the high-temperature flue gas inlet and high-temperature air outlet are fixed, and the periodic exchange of heat storage and heat release processes only occurs inside the device, making it more convenient and practical.
