[0032] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In the current optical glass melting furnace, the inlet and outlet gas pipelines of the bubbling device are connected to external fixed pipelines. When the main gas pipeline fails, bypass switching is required to ensure the normal operation of the bubbling device, that is, manually dismantling the original external gas pipeline and reconnecting it to the spare interface. This bypass switching method is cumbersome and inefficient, and the gas pipe will be dismantled during the switching process, resulting in unstable air pressure and flow, which seriously affects the bubbling control effect.

[0037] Based on this, an embodiment of the present application provides a control device and a smelting equipment for improving the stability and accuracy of bubbling control.

[0038] The following is a detailed description with reference to the accompanying drawings and specific embodiments.

[0039] Figure 1 This is a front view of the cabinet provided in an embodiment of the present application.

[0040] See also Figure 1 , a control device provided in one embodiment of the present application is used for a bubbling device, and the control device includes:

[0041] A control cabinet, the control cabinet comprises a cabinet body 10, and the cabinet body 10 has an installation space;

[0042] a first air supply unit and a second air supply unit located in the installation space;

[0043] An air path switching element 21 installed in the cabinet 10, the air path switching element 21 has a first air inlet end, a second air inlet end and a first air outlet end 211, the first air inlet end is connected to the first air supply unit, the second air inlet end is connected to the second air supply unit, and the first air outlet end 211 is connected to the bubbling device;

[0044] The first air supply unit has a first state and a second state. When the first air supply unit is in the first state, the first air inlet end is connected to the first air outlet end 211 ; when the first air supply unit is in the second state, the second air inlet end is connected to the first air outlet end 211 .

[0045] When implementing it, Figure 1When the first air supply unit changes from the first state to the second state, the air path switching element 21 is switched from being connected between the first air inlet end and the first air outlet end 211 to being connected between the second air inlet end and the first air outlet end 211; when the first air supply unit changes from the second state to the first state, the air path switching element 21 is switched from being connected between the second air inlet end and the first air outlet end 211 to being connected between the first air inlet end and the first air outlet end 211.

[0046] It can be seen from the composition structure and specific implementation process of the above control device that Figure 1 As shown, the control device includes a control cabinet, and the cabinet 10 has an installation space for accommodating internal devices, so that the control cabinet can protect the internal devices and provide a good internal working environment for the internal devices. An air supply unit for supplying air to the bubbling device is installed in the cabinet 10, and the air supply unit includes a first air supply unit, a second air supply unit and an air path switching element 21, wherein the air path switching element 21 has two air inlet ends and an air outlet end, and the two air inlet ends of the air path switching element 21 are respectively connected to the first air supply unit and the second air supply unit, and the air outlet end is connected to the bubbling device, so that the first air supply unit and the second air supply unit can both supply air to the bubbling device through the air path switching element 21. When the first air supply unit is in the first state, the first air inlet end of the air path switching element 21 is connected to the first air outlet end 211, and the first air supply unit supplies air to the bubbling device; when the first air supply unit is in the second state, the second air inlet end of the air path switching element 21 is connected to the first air outlet end 211, and the second air supply unit supplies air to the bubbling device. Based on this, when the gas supply state of the first gas supply unit changes between the first state and the second state, the first gas supply unit and the second gas supply unit can be connected to the bubbling device respectively by switching the first gas inlet end and the second gas inlet end. Compared with the current gas circuit switching method that requires dismantling the external pipeline to reconnect the interface, this branch gas intake control method is simple and convenient to operate when switching the gas circuit, and can realize undisturbed switching of the first gas supply unit and the second gas supply unit, ensuring gas stability during gas circuit switching, thereby improving the stability and accuracy of bubbling gas control.

[0047] Furthermore, the first state of the first gas supply unit may be a normal state, and the second state may be a fault state. In the normal state, the first gas supply unit supplies gas to the bubbling device, and when the first gas supply unit fails, the second gas supply unit supplies gas to the bubbling device by switching the two gas inlet ends of the gas path switching element 21.

[0048] For example, Figure 1 As shown, the two air inlet ends of the air path switching element 21 can be located in the installation space, and the air outlet end can be installed on the control cabinet body 10, so as to facilitate the connection of the bubbling device.

[0049] Exemplarily, the gas path switching element 21 may include a three-way valve.

[0050] As a possible implementation, Figure 1 As shown, the first air supply unit includes a flow meter 31, the flow meter 31 has a third air inlet end and a second air outlet end, and the second air outlet end is connected to the first air inlet end;

[0051] The flow meter 31 is used to detect the gas flow in the first gas supply unit.

[0052] Based on this, Figure 1 As shown, the first gas supply unit includes a flow meter 31, and the gas outlet end of the flow meter 31 is connected to the first gas inlet end of the gas path switching element 21, so that the flow meter 31 can detect the gas flow rate in the first gas supply unit, which is conducive to achieving precise control of the gas flow rate in the first gas supply unit, thereby facilitating accurate and stable bubbling control effect.

[0053] In some examples, in addition to the flow detection function, the flow meter 31 may also be integrated with a flow control function, thereby further achieving precise control of the gas flow in the first gas supply unit.

[0054] In some examples, the flow meter 31 may also be integrated with a fault indication function. In specific implementation, when the gas flow rate in the first gas supply unit detected by the flow meter 31 is less than or equal to a preset value, the flow meter 31 may indicate a fault, and at this time, the first gas supply unit is judged to be in the second state, that is, the fault state, and the gas path switching element 21 may be used to switch the gas path, which is conducive to the disturbance-free switching of the first gas supply unit and the second gas supply unit, and further improves the stability and accuracy of the bubbling control effect; conversely, when the flow meter 31 does not indicate a fault, it can be considered that the first gas supply unit is in the first state, that is, the normal state, and there is no need to switch the gas path.

[0055] In addition, when the first air supply unit is restored to the first state, the air path switching element 21 can also be switched from the second air inlet end being connected to the first air outlet end 211 to the first air inlet end being connected to the first air outlet end 211 .

[0056] Exemplarily, the flow meter 31 in the embodiment of the present application can be selected from commercially available gas flow meters, such as an electromagnetic flow meter, an ultrasonic flow meter, a vortex flow meter, a turbine flow meter, etc. Specifically, the model of the flow meter can be MQV0005CSRN00000, which is only used as an example and is not specifically limited.

[0057] As a possible implementation, Figure 1As shown, the control device includes at least one gas circuit switching element 21, the first air supply unit includes a flow meter 31 corresponding to the gas circuit switching element 21, and each second gas outlet is connected to the first gas inlet of the corresponding gas circuit switching element 21.

[0058] like Figure 1 As shown, in actual production, the control device can be connected to at least one bubbling device. At this time, the control device is equipped with gas path switching elements 21 corresponding to the bubbling devices one by one, and flow meters 31 corresponding to the gas path switching elements 21 one by one. The outlet end of each flow meter 31 is connected to the first inlet end of the corresponding gas path switching element 21, and the outlet end of each gas path switching element 21 is connected to the inlet of the corresponding bubbling device, so that the control device can independently control the gas flow flowing to each bubbling device, thereby realizing independent control of the bubbling effect of each bubbling device, and further improving the accuracy and stability of the bubbling control effect.

[0059] For example, Figure 1 As shown, five gas path switching elements 21 can be installed in the control device, and the first gas supply unit includes five flow meters 31 connected to the gas path switching elements 21 one by one. At this time, the control device can be connected to five bubbling devices, and each bubbling device is connected to one gas path switching element 21. This is only an example and is not specifically limited.

[0060] In some examples, such as Figure 1 As shown, the first air supply unit also includes a first air distributor 32 , which has a fourth air inlet end and third air outlet ends 321 corresponding one to each of the flow meters 31 , and each third air outlet end 321 is connected to the third air inlet end of the corresponding flow meter 31 .

[0061] Based on this, Figure 1 As shown, in the case where the control device includes at least one gas path switching element 21 and the first gas supply unit includes a flow meter 31 corresponding one-to-one to the gas path switching element 21, the first gas supply unit may also include a first gas distributor 32, the first gas distributor 32 having an air inlet end and air outlet ends corresponding to the number of flow meters 31, and each air outlet end of the first gas distributor 32 is connected to the air inlet end of the corresponding flow meter 31, so that the gas flowing into the first gas distributor 32 can be distributed to different flow meters 31 through different air outlet ends, and then the air supply to different bubbling devices is realized through the gas path switching elements 21 corresponding one-to-one to the flow meters 31, which is conducive to further realizing the independent control of at least one bubbling device by the control device, and further improving the accuracy and stability of the bubbling control effect.

[0062] For example, Figure 1As shown, when five gas path switching elements 21 are installed in the control device, and the first gas supply unit includes five flow meters 31 corresponding one to one with the gas path switching elements 21, the first gas distribution cylinder 32 can have five gas outlet ends connected one to one with the flow meters 31. This is only an example and is not specifically limited.

[0063] In some examples, such as Figure 1 As shown, the control device further includes a first air supply port 33 installed on the cabinet 10, and an external gas source supplies gas to the first air supply unit through the first air supply port 33;

[0064] The control device further includes a first air pressure regulating member 34 located in the installation space. The first air pressure regulating member 34 has a fifth air inlet end and a fourth air outlet end. The fifth air inlet end is connected to the first air supply port 33, and the fourth air outlet end is connected to the fourth air inlet end.

[0065] Based on this, Figure 1 As shown, the external gas source can supply gas to the first gas supply unit through the first gas supply port 33 installed on the control cabinet body 10. The gas inlet end of the first gas pressure regulating member 34 is connected to the first gas supply port 33, and the gas outlet end is connected to the gas inlet end of the first gas distributor 32. The first gas pressure regulating member 34 can control the pressure and flow rate of the gas in the first gas supply unit, which is conducive to ensuring the stability of the gas pressure, thereby further improving the accuracy and stability of the bubbling control effect.

[0066] Illustratively, in the first gas supply unit, the gas introduced from the first gas supply port 33 can flow through the first gas pressure regulating component 34 and the first gas distributor 32 in sequence, and then flow from the outlet end of the first gas distributor 32 to the corresponding flow meter 31 and the second gas inlet end of the gas pressure switching element. When the first gas supply unit is in the first state, the gas flowing through the first gas supply unit supplies gas to the corresponding bubbling device through the outlet end of the gas pressure switching element.

[0067] For example, the first gas pressure regulating component 34 may include a pressure reducing valve.

[0068] Exemplarily, the first air supply unit also includes a first connecting pipe (not shown in the figure), which is at least used to connect the first air supply port 33 and the air inlet end of the first air pressure regulating component 34, connect the air outlet end of the first air pressure regulating component 34 and the air inlet end of the first air distributor 32, and connect the air outlet end of the first air distributor 32 and the air inlet end of the corresponding flow meter 31.

[0069] In some examples, such as Figure 1 As shown, the second air supply unit includes a second air distributor 41, the second air distributor 41 has a sixth air inlet end and fifth air outlet ends 411 corresponding to the air path switching elements 21 one by one, and each fifth air outlet end 411 is connected to the second air inlet end of the corresponding air path switching element 21;

[0070] The control device further includes a second air supply port 42 mounted on the cabinet 10, and an external gas source supplies gas to the second air supply unit through the second air supply port 42;

[0071] The control device also includes a second air pressure regulating member 43 located in the installation space. The second air pressure regulating member 43 has a seventh air inlet end and a sixth air outlet end. The seventh air inlet end is connected to the second air supply port 42, and the sixth air outlet end is connected to the sixth air inlet end.

[0072] Based on this, Figure 1 As shown, in the case where the control device includes at least one gas path switching element 21, the second gas supply unit may include a second gas distributor 41, the second gas distributor 41 having an inlet end and an outlet end corresponding to the number of gas path switching elements 21, and each outlet end of the second gas distributor 41 is connected to the second inlet end of the corresponding gas path switching element 21, so that the gas flowing into the second gas distributor 41 can be distributed to the second inlet ends of different gas path switching elements 21 through different outlet ends, so as to realize the gas supply to different bubbling devices, which is conducive to further realizing the independent control of at least one bubbling device by the control device, and further improving the accuracy and stability of the bubbling control effect. The external gas source can supply gas to the second gas supply unit through the second gas supply port 42 installed on the control cabinet body 10. The inlet end of the second air pressure regulating member 43 is connected to the second gas supply port 42, and the outlet end is connected to the inlet end of the second gas distributor 41. The second gas pressure regulating member 43 can control the pressure and flow rate of the gas in the second gas supply unit, which is beneficial to ensure the stability of the gas pressure, thereby facilitating further improving the accuracy and stability of the bubbling control effect.

[0073] For example, Figure 1 As shown, when five gas path switching elements 21 are installed in the control device, the second gas distribution cylinder 41 has five gas outlets connected to the gas path switching elements 21 in a one-to-one correspondence. This is only an example and is not specifically limited.

[0074] Illustratively, in the second gas supply unit, the gas introduced from the second gas supply port 42 can flow through the second gas pressure regulating member 43 and the second gas distributor 41 in sequence, and then flow from the outlet end of the second gas distributor 41 to the second gas inlet end of the corresponding gas pressure switching element. When the first gas supply unit is in the second state, the gas flowing through the second gas supply unit supplies gas to the corresponding bubbling device through the outlet end of the gas pressure switching element.

[0075] Exemplarily, the second gas pressure regulating member 43 may include a pressure reducing valve.

[0076] Exemplarily, the second air supply unit also includes a second connecting pipe (not shown in the figure), which is at least used to connect the second air supply port 42 and the air inlet end of the second air pressure regulating component 43, connect the air outlet end of the second air pressure regulating component 43 and the air inlet end of the second air distributor 41, and connect the air outlet end of the second air distributor 41 and the second air inlet end of the corresponding air pressure switching element.

[0077] When the current optical glass melting furnace bubbling control device is in use, factors such as high temperature and dust on site will affect the normal operation of the bubbling device.

[0078] Therefore, the protection structure of the control cabinet can be improved to enhance the protection capability of the control cabinet, so that the control cabinet has dustproof and outdoor waterproof effects. The protection level of the control cabinet can reach IP56 to ensure the normal operation of the internal components. The following is a detailed explanation.

[0079] Figure 2 This is a front view of the cabinet door provided in an embodiment of the present application.

[0080] As a possible implementation, combining Figure 1 and Figure 2 The control cabinet further includes a cabinet door 11, and the cabinet door 11 and the cabinet body 10 enclose an installation space;

[0081] The cabinet door 11 has a first port, and the cabinet body 10 has a second port, and the cabinet door 11 cooperates with the second port of the cabinet body 10 through the first port;

[0082] The control cabinet further includes a protection member 12 located at the first port and / or at the second port.

[0083] Based on this, combined Figure 1 and Figure 2 The cabinet door 11 and the cabinet body 10 of the control cabinet enclose an installation space for accommodating internal devices, and the cabinet body 10 and the cabinet door 11 can jointly protect the internal devices. The cabinet door 11 has a first port on the side facing the cabinet body 10, and the cabinet body 10 has a second port on the end facing the cabinet door 11. The installation of the cabinet door 11 and the cabinet body 10 can be achieved through the mutual cooperation of the first port and the second port. Furthermore, a protective member 12 can be added at the position of the first port and / or the second port, so that the first port can cooperate with the second port through the protective member 12 to achieve a tight installation of the cabinet door 11 and the cabinet body 10, thereby improving the sealing performance and protection performance of the control cabinet, and can effectively prevent dust, splashing water, etc. from invading the interior of the control device, which is conducive to providing a safe and stable internal working environment for the internal devices of the control device.

[0084] In some examples, the protective member 12 may be installed at the first port of the cabinet door 11, or may be installed at the first port of the cabinet door 11. Figure 1As shown, the protective member 12 is installed at the second port of the cabinet 10, or the protective member 12 can be installed at the first port of the cabinet door 11 and the second port of the cabinet 10. For example, the protective member 12 is installed at the second port of the cabinet 10, which is only an example and is not specifically limited.

[0085] Exemplarily, the protective member 12 may include a protective rubber strip, which is only used as an example and is not specifically limited.

[0086] In some examples, the first port has a groove, and the second port has a protrusion matching the groove; or the second port has a groove, and the first port has a protrusion matching the groove.

[0087] Based on this, the protective member 12 can increase the contact area with the first port and the second port through the concave-convex structure. At the same time, the contact between the protective member 12 and the first port and the second port is closer, so that the cabinet door 11 and the cabinet body 10 can be further tightly installed, further improving the sealing performance and protection performance of the control cabinet, thereby further preventing dust, splashing water, etc. from invading the interior of the control device, which is beneficial to further provide a safe and stable internal working environment for the internal components of the control device.

[0088] In some examples, the materials of the control cabinet body 10 and the cabinet door 11 may be improved. At least the outer surfaces of the control cabinet body 10 and the cabinet door 11 may be made of materials with high efficiency in waterproofing and dustproofing.

[0089] When the current optical glass melting furnace bubbling control device is in use, the internal instruments of the bubbling control device are used in a high temperature environment for a long time, which is prone to failures such as component aging and control circuit failure.

[0090] As a possible implementation, Figure 1 As shown, the control device further comprises a cooling unit located in the installation space, and the cooling unit comprises a radiator 51 and a blowing element.

[0091] Among them, Figure 1 As shown, the radiator 51 has a heat dissipation function and can cool down the air near the radiator 51. The blowing element can accelerate the air flow in the installation space by blowing air, and accelerate the circulation of cold air around the radiator 51 and the hot air in the installation space. Therefore, the overall cooling of the installation space can be achieved through the cooperation of the radiator 51 and the blowing element, which is beneficial to further provide a safe and stable internal working environment for the internal components of the control device, avoid excessive internal temperature of the control device, cause internal component failure, and further improve the stability of the bubbling control effect.

[0092] Exemplarily, the blowing element may be installed in the installation space around the radiator 51, or the blowing element may be fixedly connected to the radiator 51, which is only an example and not specifically limited here.
