In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0033] As Figure 1 shown, an embodiment of the present application provides a heat recovery constant temperature device, and the heat recovery constant temperature device includes a temperature adjustment component and a heat exchange component. Among them, the temperature adjustment component adjusts the tail gas to an appropriate temperature by heating and cooling the tail gas in real time. The tail gas at the appropriate temperature then reaches the heat exchange component, and heat transfer is performed on the standby gas in the heat exchange component to keep the standby gas at a constant temperature, facilitating the introduction of the standby gas into a combustion chamber or a drying chamber with relatively strict temperature requirements.

[0034] In some examples, the temperature regulating component includes a temperature regulating chamber 101 for introducing tail gas. Here, the tail gas comes from a ceramic drying chamber or an electroceramic drying chamber and carries a large amount of thermal energy. The heat recovery constant temperature device of the present application utilizes the thermal energy in such tail gas to heat the standby gas for subsequent use in the drying chamber, recycling the thermal energy. It can be understood that the standby gas with a certain amount of heat can promote the drying process in the drying chamber.

[0035] Among them, the temperature regulating component further includes a heating component and a cooling component. When the temperature of the tail gas is too low, the heating component starts to increase the temperature of the tail gas; when the temperature of the tail gas is too high, the cooling component starts to decrease the temperature of the tail gas. The heating component and the cooling component are adjusted in real time according to the current temperature of the tail gas to ensure that the tail gas is at an appropriate temperature. The tail gas at an appropriate temperature heats the standby gas, so that the standby gas is introduced into the drying chamber at a constant temperature, suitable for the drying process with relatively strict temperature requirements.

[0036] In some examples, the temperature regulating component includes a temperature regulating housing 102. The temperature regulating housing 102 is hollow and generally formed into a cylindrical structure, and the hollow part of the temperature regulating housing 102 defines the temperature regulating chamber 101.

[0037] Furthermore, to facilitate the introduction of the tail gas from the drying chamber into the temperature regulating housing 102 so that the temperature regulating chamber 101 receives the tail gas, the temperature regulating housing 102 is provided with a tail gas inlet 103.

[0038] Among them, on the one hand, the tail gas inlet 103 communicates with the temperature regulating chamber 101, and on the other hand, it communicates with the drying chamber. At the same time, the tail gas inlet 103 is located on the side wall of the temperature regulating housing 102 and extends a certain distance outward from the temperature regulating housing 102, so the tail gas inlet 103 is generally formed into a cylindrical structure.

[0039] In some examples, the heating component includes a burner 104, and the working part of the burner 104 is located inside the temperature regulating chamber 101. When the temperature of the tail gas is insufficient, the burner 104 burns inside the temperature regulating chamber 101 to increase the temperature of the tail gas in the temperature regulating chamber 101 and promote the tail gas to reach the preset appropriate temperature. Among them, the burner 104 is connected to the end of the temperature regulating housing 102.

[0040] In some examples, the cooling component includes a cooling medium inlet 105. The cooling medium inlet 105 communicates with the temperature regulating chamber 101, and the cooling medium inlet 105 is used to introduce the cooling medium into the temperature regulating housing 102. Then the temperature regulating chamber 101 receives the cooling medium, and the cooling medium is used to decrease the temperature of the tail gas. Among them, the cooling medium includes fresh air with a lower temperature.

[0041] Specifically, the cooling medium inlet 105 is provided on the side wall of the temperature regulating housing 102. At the same time, the cooling medium inlet 105 extends a certain distance outward from the temperature regulating housing 102, so the cooling medium inlet 105 is generally formed in a cylindrical structure. In addition, the cooling medium inlet 105 and the tail gas inlet 103 are located on opposite sides of the temperature regulating housing 102.

[0042] It can be understood that when the temperature of the tail gas is too high, the cooling medium enters the temperature regulating chamber 101 along the cooling medium inlet 105, thereby reducing the temperature of the tail gas in the temperature regulating chamber 101 and promoting the tail gas to reach the preset appropriate temperature. At this time, in the temperature regulating chamber 101, the tail gas and the cooling medium form a mixed gas.

[0043] In some examples, to ensure sufficient mixing of the tail gas and the cooling medium and evenly reduce the temperature of the tail gas, the heat recovery constant temperature device further includes a mixing component.

[0044] Among them, since the mixed gas is in the temperature regulating chamber 101, the mixing component is also in the temperature regulating chamber 101, that is, inside the temperature regulating housing 102. The mixing component is used to change the flow path of the mixed gas, thereby disturbing the mixed gas, so that the tail gas and the cooling medium are evenly mixed, ensuring that the mixed gas evenly reaches the appropriate temperature.

[0045] As Figure 1 shown, in some examples, the mixing component includes a plurality of blocking members 106. The blocking members 106 are generally formed in a plate-like structure, and the blocking members 106 are arranged at intervals.

[0046] Furthermore, for a single blocking member 106, the blocking member 106 is connected to one side of the inner wall of the temperature regulating housing 102 and extends to the opposite side. During the extension process, a gap is left between the blocking member 106 and the opposite side of the inner wall of the temperature regulating housing 102 to facilitate the construction of a passage for the mixed gas to pass through.

[0047] For two adjacent blocking members 106, the two adjacent blocking members 106 are respectively connected to opposite sides of the inner wall of the housing, so the gaps between the two adjacent blocking members 106 and the inner wall of the temperature regulating housing 102 are misaligned.

[0048] When the mixed gas passes through the mixing assembly, under the limiting effect of the first blocking component 106, the mixed gas first passes through the gap between the first blocking component 106 and the inner wall of the temperature regulating shell 102; under the blocking effect of the second blocking component 106, the flow path of the mixed gas changes, so that it passes through the gap between the second blocking component 106 and the inner wall of the temperature regulating shell 102, and so on, the mixed gas finally passes through the entire mixing assembly. In this process, each blocking component 106 disturbs the mixed gas, disrupts and reorganizes the mixed gas, so as to ensure that the exhaust gas and the cooling medium are evenly mixed. Specifically, the mixing assembly includes three blocking components 106.

[0049] It can be understood that the plurality of blocking components 106 define a curved mixed gas channel, and the first mixed gas path 107 defined by the mixed gas channel is as shown in FIG. Figure 2 shown.

[0050] In addition, the surface of the blocking component 106 is provided with spoiler holes, the shape of the spoiler holes is roughly formed into a cone, and the spoiler holes are conducive to uniform mixing of the exhaust gas and the cooling medium.

[0051] In some examples, the heat exchange assembly includes a heat exchange chamber 201, which receives the unused gas on one hand and introduces the heated unused gas into the drying chamber on the other hand, thereby promoting the drying process. Specifically, the unused gas includes fresh cold air.

[0052] The heat exchange chamber 201 is connected to the temperature adjustment chamber 101, so that the mixed gas adjusted to a suitable temperature can enter the heat exchange chamber 201. In the heat exchange chamber 201, the mixed gas heats the standby gas by heat transfer, so that the standby gas is heated. Since the temperature of the mixed gas can be adjusted in real time, it is convenient to ensure that the standby gas is in a constant temperature state after heating. The constant temperature standby gas is further introduced into the drying chamber, which can meet the temperature requirements of the drying chamber for the standby gas.

[0053] In some examples, the heat exchange assembly includes a heat exchange shell 202, which is hollow and generally formed into a cylindrical structure, and the hollow portion of the heat exchange shell 202 defines a heat exchange cavity 201. At the same time, in order to facilitate the communication between the temperature adjustment cavity 101 and the heat exchange cavity 201, the end of the temperature adjustment shell 102 close to the heat exchange shell 202 is open, and the end of the heat exchange shell 202 close to the temperature adjustment shell 102 is also open, and the open ends of the temperature adjustment shell 102 and the heat exchange shell 202 are connected to each other, so that the mixed gas can reach the heat exchange cavity 201.

[0054] Further, the mixed gas after heating the gas to be used needs to be discharged from the heat exchange chamber 201. Then, the heat exchange housing 202 is provided with an exhaust gas outlet 203, and the mixed gas is discharged from the heat recovery constant temperature device along the exhaust gas outlet 203. It can be understood that the exhaust gas outlet 203 communicates with the heat exchange chamber 201. Specifically, as Figure 3 shown, the exhaust gas outlet 203 is provided at the end of the heat exchange housing 202 away from the temperature control housing 102, and a second mixed gas path 204 leading to the exhaust gas outlet 203 is formed in the heat exchange chamber 201.

[0055] In some examples, the heat exchange housing 202 is provided with a gas inlet 205 and a gas outlet 206. Both the gas inlet 205 and the gas outlet 206 communicate with the heat exchange chamber 201. The gas to be used enters the heat exchange chamber 201 along the gas inlet 205 for heating, and the heated gas to be used is then led out of the heat exchange chamber 201 along the gas outlet 206. It can be understood that the gas outlet 206 communicates with the drying chamber, facilitating the further introduction of the gas to be used into the drying chamber.

[0056] Specifically, the gas inlet 205 and the gas outlet 206 are adjacently arranged and are on the side wall of the heat exchange housing 202. Then, the gas inlet 205, the gas outlet 206, and the heat exchange chamber 201 form a channel for the gas to be used to flow. The gas path 207 defined by the gas path for the gas to be used is shown in Figure 3 .

[0057] Among them, there is an overlap between the gas path 207 for the gas to be used and the second mixed gas path 204, ensuring that the mixed gas can increase the temperature of the gas to be used in a heat transfer manner.

[0058] As Figure 1 and Figure 4 shown, in some examples, the temperature control assembly further includes a combustion control assembly. The control part of the burner 104 extends out of the temperature control chamber 101 and is connected to the combustion control assembly.

[0059] Among them, the combustion control assembly includes a fuel channel 301, a combustion-supporting medium channel 302, and a humidity control channel 303. The fuel channel 301 is connected to the burner 104 to supply fuel to the burner 104. Specifically, the fuel required by the burner 104 includes gas.

[0060] Further, the combustion-supporting medium channel 302 is connected to the fuel channel 301. Then, the combustion-supporting medium channel 302 is indirectly connected to the burner 104, and the combustion-supporting medium channel 302 supplies the combustion-supporting medium to the burner 104. Specifically, the combustion-supporting medium includes fresh air.

[0061] Meanwhile, the humidity control channel 303 is connected to the fuel channel 301. Then the humidity control channel 303 is also indirectly connected to the burner 104. The humidity control channel 303 supplies a liquid substance to the burner 104, thereby adjusting the humidity during the combustion process of the burner 104.

[0062] In addition, valves 304 are provided in the fuel channel 301, the combustion-supporting medium channel 302, and the humidity control channel 303. The amount of material supplied to the burner 104 is controlled by the opening degree of the valves 304, thereby controlling the intensity of combustion of the burner 104. The intensity of combustion of the burner 104 determines the temperature rise range of the tail gas.

[0063] As Figure 1 and Figure 5 shown, in some examples, the heat recovery and constant temperature device further includes a detection component. The detection component includes a flame detection component 403, a concentration detection component 404, and several temperature detection components 402. The temperature detection components 402 are used to detect the temperatures in the temperature adjustment chamber 101 and the heat exchange chamber 201. Then the temperature detection components 402 are arranged on the temperature adjustment housing 102 and the heat exchange housing 202. Specifically, several temperature detection components 402 are arranged on the heat exchange housing 202, and each temperature detection component 402 is arranged at the positions of the gas inlet 205, the gas outlet 206, and the tail gas outlet 203. Further, the flame detection component 403 and the concentration detection component 404 are arranged on the temperature adjustment housing 102.

[0064] It should be noted that the heat recovery and constant temperature device further includes a controller 401. The flame detection component 403, the concentration detection component 404, the temperature detection components 402, and each valve 304 are electrically connected to the controller 401.

[0065] In the temperature adjustment component part, if the flame detection component 403, the concentration detection component 404, or the temperature detection component 402 detects in real time that the temperature adjustment process in the temperature adjustment chamber 101 does not meet the standard, the flame detection component 403, the concentration detection component 404, or the temperature detection component 402 sends a signal to the controller 401. The controller 401 controls the opening degree of each valve 304 and the amount of the cooling medium introduced, thereby ensuring that the mixed gas is accurately adjusted to an appropriate temperature.

[0066] In the heat exchange component part, if each temperature detection component 402 detects in real time that the temperature at a certain position in the temperature adjustment chamber 101 does not meet the standard, the corresponding temperature detection component 402 sends a signal to the controller 401. The controller 401 controls the opening degree of each valve 304 and the amount of the cooling medium introduced, thereby ensuring that the standby gas is adjusted to an appropriate temperature and is in a constant temperature state.

[0067] During the actual implementation process, the exhaust gas is passed into the temperature regulating chamber 101, the burner 104 can increase the temperature of the exhaust gas, and the introduction of the cooling medium can reduce the temperature of the exhaust gas. Under the real-time monitoring of the detection component, the controller 401 controls the combustion process of the burner 104 and the introduction process of the cooling medium to ensure that the mixed gas formed by the exhaust gas and the cooling medium is at an appropriate temperature; the stand-by gas is passed into the heat exchange chamber 201, and the mixed gas transfers heat to the stand-by gas in the heat exchange chamber 201 to increase the temperature of the stand-by gas. Under the real-time monitoring of the temperature control component, the controller 401 further regulates the temperature of the stand-by gas to ensure that the stand-by gas is introduced into the drying chamber under a constant temperature state, and the mixed gas after the heat transfer is discharged from the heat recovery constant temperature device along the exhaust gas outlet 203.
