Description

Technical Field

[0001] This invention relates to the field of bag drying equipment technology, and in particular to a bag drying equipment lid and a bag drying equipment. Background Technology

[0002] Currently, in the production process of ductile iron and gray iron casting, transfer ladles are usually used to transfer molten iron. The transfer ladle is made of refractory material and is knotted. Before transfer, the ladle must be sintered at high temperature using a ladle dryer to remove moisture from the ladle and bring it to the target operating temperature. This avoids the molten iron temperature being affected by the large temperature difference between the transfer ladle and the molten iron during transfer, and also avoids molten iron splashing caused by excessive moisture in the ladle.

[0003] In related technologies, baking ovens typically use steel burners to spray flames for high-temperature sintering. However, traditional steel burners have low temperature resistance and short service life. During the use of the burner, the flame is ejected from the burner and can directly bake the area near the nozzle. Therefore, when the burner is used too frequently or the high-temperature baking time is too long, it is easy to cause burner erosion and damage, thereby reducing the burner's service life and requiring frequent replacement and repair, which leads to increased costs. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first objective of the present invention is to provide a cover for a burner, which surrounds the first section of the burner with a heat insulation element, thereby preventing the flame emitted from the burner from directly baking the nozzle of the burner, reducing the temperature of the burner during operation, which helps to extend the service life of the burner, and thus saves costs.

[0005] The second objective of this invention is to provide a bread drying device.

[0006] To achieve the above objectives, a first aspect of the present invention provides a bread drying oven lid, comprising:

[0007] The housing has a first side and a second side disposed opposite to each other, and the housing forms an installation space and an installation hole communicating with the installation space, the installation space being located between the first side and the second side;

[0008] The burner is inserted through the mounting hole along the height direction of the housing, and the burner has a first section and a second section that are connected. The first section extends out of the mounting hole from the first side, and the second section extends out of the mounting hole from the second side.

[0009] The thermal insulation component is partially fixed within the installation space, and the thermal insulation component surrounds and covers the first section, with the lower end of the thermal insulation component flush with the lower end of the first section.

[0010] According to the embodiment of the present invention, the cover of the baking oven surrounds the first section of the burner by means of a heat insulation element, which can prevent the flame emitted by the burner from directly baking the nozzle of the burner, thereby reducing the temperature of the burner during operation, which is beneficial to extending the service life of the burner and thus saving costs.

[0011] According to some examples of the present invention, the housing includes a side wall and a top wall, the side wall being disposed around the top wall to jointly define an installation space, and the top wall being provided with an installation hole.

[0012] According to some examples of the present invention, the thermal insulation component includes a first sub-thermal insulation component and a second sub-thermal insulation component connected together. The first sub-thermal insulation component is fixed in the installation space, and the second sub-thermal insulation component is located outside the housing, with the lower end of the second sub-thermal insulation component flush with the lower end of the first segment.

[0013] According to some examples of the present invention, the side surface of the second sub-insulation member and the bottom surface of the first sub-insulation member have an included angle α, satisfying the relationship 90°<α<180°.

[0014] According to some examples of the present invention, it further includes: a first intake pipe and a second intake pipe, wherein the first intake pipe is disposed in the second section and communicates with the burner;

[0015] The second intake pipe has a first sub-pipe, a second sub-pipe, and a third sub-pipe. The second sub-pipe is fixed in the installation space and surrounds the first section. The first sub-pipe passes through the housing and communicates with the second sub-pipe, and a portion of the first sub-pipe extends out to the second side. The third sub-pipe passes through the housing and communicates between the second sub-pipe and the second section.

[0016] According to some examples of the invention, the second sub-pipe is fixed to the inner surface of the top wall.

[0017] According to some examples of the invention, a portion of the first intake pipe extends into the burner.

[0018] According to some examples of the invention, the first intake pipe is arranged concentrically with the burner.

[0019] According to some examples of the invention, it further includes: a thermal insulation element disposed within the installation space and sandwiched between the thermal insulation element and the housing.

[0020] To achieve the above objectives, a second aspect of the present invention provides a bag drying device, including the bag drying device cover of the first aspect embodiment.

[0021] According to the embodiments of the present invention, the baking oven, by providing the above-mentioned baking oven cover, surrounds the first section of the burner with the heat insulation member, which can prevent the flame emitted by the burner from directly baking the nozzle position of the burner, thereby reducing the temperature of the burner during operation, which is beneficial to extending the service life of the burner and thus saving costs.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following description, with reference to the accompanying drawings, illustrates an embodiment of the bread drying apparatus lid 100 and the bread drying apparatus according to the present invention.

[0035] like Figure 1As shown, the cover 100 of the bread dryer according to a first aspect embodiment of the present invention includes: a housing 1, a burner 2, and a heat insulation member 3. The housing 1 has a first side 11 and a second side 12 disposed opposite to each other. The housing 1 forms an installation space 13 and an installation hole 14 communicating with the installation space 13. The installation space 13 is located between the first side 11 and the second side 12. The burner 2 is disposed through the installation hole 14 along the height direction of the housing 1, and the burner 2 has a first section 21 and a second section 22 communicating with each other. The first section 21 extends out of the first side 11 from the installation hole 14, and the second section 22 extends out of the second side 12 from the installation hole 14. A portion of the heat insulation member 3 is fixed in the installation space 13. The heat insulation member 3 surrounds and covers the first section 21, and the lower end of the heat insulation member 3 is flush with the lower end of the first section 21.

[0036] Specifically, according to the 100-fold lid of the baking pan... Figure 1 Taking the placement direction shown as an example, the housing 1 has a first side 11 and a second side 12 arranged opposite to each other, wherein the first side 11 is the lower side of the housing 1 and the second side 12 is the upper side of the housing 1. Further, the housing 1 has an open mounting space 13 located between the first side 11 and the second side 12. The burner 2 can be made of steel and is inserted into the mounting hole 14 along the height direction of the housing 1. The burner 2 has a first section 21 and a second section 22 that are connected. The first section 21 extends out of the mounting hole 14 from the first side 11, and the second section 22 extends out of the mounting hole 14 from the first side 11. On both sides 12, that is, the burner 2 passes through the mounting hole 14 of the housing 1 from top to bottom, and a part of the burner 2 (first section 21) extends out after passing through the mounting space 13. The lower end of the first section 21 is outside the housing 1, and the other part of the burner 2 (second section 22) extends upward from the mounting hole 14, that is, the upper end of the second section 22 is outside the housing 1. It can be understood that the lower side of the drying bag cover 100 is set opposite to the transfer bag. When the drying bag cover 100 is placed over the opening at the top of the transfer bag, the burner 2 can extend into the transfer bag, thereby spraying flames through the burner 2 to sinter the transfer bag at high temperature.

[0037] However, the maximum temperature resistance of traditional steel burners 2 is 1250℃-1350℃, while the temperature of molten iron in the transfer ladle is usually greater than 1400℃. To meet the requirements for carrying molten iron, the sintering temperature of the transfer ladle must be at least greater than or equal to 1100℃. Therefore, a jet flame with a temperature greater than 1200℃ is required for sintering. During the use of burner 2, the flame is ejected from burner 2, and the ejected flame directly bakes the area near the nozzle of burner 2. When the temperature is greater than 1200℃ and baking continues, burner 2 becomes red-hot due to the high temperature, causing burner 2 to be eroded and damaged, thereby reducing the service life of burner 2. The damaged burner 2 will affect the flame shape, making it unable to better penetrate into the bottom of the molten iron ladle, thus affecting the sintering quality of the transfer ladle. Therefore, burner 2 needs to be replaced and repaired frequently, leading to increased costs.

[0038] Based on this, the cover 100 of the drying oven in this application is also provided with a heat insulation component 3. The heat insulation component 3 can be made of refractory material. Generally speaking, the refractory material can be selected with a temperature resistance of 1650℃-1750℃. (Continue to refer to...) Figure 1 As shown, part of the thermal insulation component 3 is fixedly installed in the installation space 13. For example, a V-shaped iron claw is formed inside the housing 1, which provides a force point for fixing the thermal insulation component 3. Furthermore, the heat insulation element 3 surrounds and covers the first section 21 of the burner 2, with the lower end of the heat insulation element 3 flush with the lower end of the first section 21. This allows the first section 21 of the burner 2 (used for spraying flames) to be covered and isolated by the heat insulation element 3. When the first section 21 of the burner 2 sprays flames toward the interior of the transfer bag, the heat insulation element 3 can isolate the flames from the burner 2, thereby preventing the flames from directly baking the area near the nozzle of the burner 2, reducing the operating temperature of the burner 2, and effectively improving the service life of the burner 2. At the same time, when the transfer bag is sintered at high temperature, since the heat insulation element 3 can reduce the temperature of the burner 2, the baking temperature can be increased without affecting the service life of the burner 2, for example, to a baking temperature greater than 1300℃. This is beneficial to improving the sintering quality of the transfer bag. Moreover, the refractory material has a lower thermal conductivity than steel, which can reduce heat loss and help save energy.

[0039] According to the embodiment of the present invention, the cover 100 of the baking oven surrounds the first section 21 of the burner 2 with the heat insulation member 3, which can prevent the flame emitted by the burner 2 from directly baking the nozzle position of the burner 2, reduce the temperature of the burner 2 during operation, and help extend the service life of the burner 2, thereby saving costs.

[0040] In some embodiments of the present invention, such as Figure 1 As shown, the housing 1 includes a side wall 15 and a top wall 16. The side wall 15 is arranged around the top wall 16 to jointly define the mounting space 13. The top wall 16 is provided with mounting holes 14. Specifically, the housing 1 is composed of the interconnected side wall 15 and top wall 16. The side wall 15 is located below the top wall 16 and is arranged around the top wall 16. For example, the side wall 15 can be arranged in a circle around the top wall 16 or in a square shape, depending on the actual needs. No specific limitation is made here. Furthermore, the top wall 16 is provided with mounting holes 14. That is to say, the burner 2 passes through the top wall 16 of the housing 1 from top to bottom. The lower end of a part of the burner 2 (first segment 21) is located below the side wall 15, and the upper end of another part of the burner 2 (second segment 22) is located above the top wall 16. This arrangement simplifies the structure of the housing 1, facilitates the assembly between the housing 1 and the burner 2, and helps to improve assembly efficiency.

[0041] In some embodiments of the present invention, such as Figure 1As shown, the thermal insulation component 3 includes a first sub-thermal insulation component 31 and a second sub-thermal insulation component 32 connected together. The first sub-thermal insulation component 31 is fixed in the installation space 13, and the second sub-thermal insulation component 32 is located outside the housing 1, and the lower end of the second sub-thermal insulation component 32 is flush with the lower end of the first segment 21. Specifically, the heat insulation component 3 consists of a first sub-heat insulation component 31 and a second sub-heat insulation component 32. The first sub-heat insulation component 31 is fixedly installed in the installation space 13 of the housing 1. The second sub-heat insulation component 32 is located below the first sub-heat insulation component 31 and is fixedly connected to the first sub-heat insulation component 31. It can be understood that both the first sub-heat insulation component 31 and the second sub-heat insulation component 32 are arranged to surround and cover the burner 2, and the lower end of the second sub-heat insulation component 32 is flush with the lower end of the first section 21. With this arrangement, the second sub-heat insulation component 32 can provide key protection for the area near the nozzle of the burner 2, so as to prevent the flame emitted by the burner 2 from directly baking the area near the nozzle of the burner 2, reducing the temperature of the burner 2 during operation, and effectively improving the service life of the burner 2.

[0042] It should be noted that both the first sub-insulation component 31 and the second sub-insulation component 32 can be made of refractory materials used in casting furnace construction. The first sub-insulation component 31 and the second sub-insulation component 32 can be sintered together, forming a solid protective insulation layer after molding. The later maintenance of the second sub-insulation component 32 can be done at the same time as the maintenance of the first sub-insulation component 31. Moreover, the later maintenance can be done directly by applying mud, and the material is the same as the refractory material used for furnace repair and lining repair, making the maintenance operation simple.

[0043] In some embodiments of the present invention, such as Figure 1 As shown, the side surface of the second sub-insulation component 32 and the bottom surface of the first sub-insulation component 31 have an included angle α, satisfying the relationship 90°<α<180°. That is to say, the bottom surfaces of the second sub-insulation component 32 and the first sub-insulation component 31 have a certain included angle α, and the included angle α is greater than 90° and less than 180°. In other words, the bottom surfaces of the second sub-insulation component 32 and the first sub-insulation component 31 have a certain tilt angle. The second sub-insulation component 32 has an inverted conical structure. This design facilitates the installation and adjustment of the second sub-insulation component 32, and while meeting the insulation requirements, it also helps to reduce the weight of the second sub-insulation component 32.

[0044] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, it also includes: a first air intake pipe 4 and a second air intake pipe 5. The first air intake pipe 4 is located in the second section 22 and is connected to the burner 2. The second air intake pipe 5 has a first sub-pipe 51, a second sub-pipe 52 and a third sub-pipe 53. The second sub-pipe 52 is fixed in the installation space 13 and surrounds the first section 21. The first sub-pipe 51 passes through the housing 1 and is connected to the second sub-pipe 52. A portion of the first sub-pipe 51 extends out of the second side 12. The third sub-pipe 53 passes through the housing 1 and is connected between the second sub-pipe 52 and the second section 22.

[0045] Specifically, such as Figure 1 As shown, the first air intake pipe 4 is used to transport gas, and the second air intake pipe 5 is used to transport combustion air. The first air intake pipe 4 is located in the second section 22 and is connected to the burner 2. The first air intake pipe 4 supplies gas to the burner 2. It should be noted that the connection between the first air intake pipe 4 and the second section 22 of the burner 2 is sealed to prevent gas leakage.

[0046] Further, refer to Figure 1 and Figure 2 As shown, the second air intake pipe 5 includes a first sub-pipe 51, a second sub-pipe 52, and a third sub-pipe 53 connected in sequence. The air inlet of the first sub-pipe 51 is located outside the housing 1. The second sub-pipe 52 is fixedly installed in the installation space 13 and is arranged around the first section 21 of the burner 2. The third sub-pipe 53 is connected between the second sub-pipe 52 and the burner 2. In this way, air from the second air intake pipe 5 can be delivered to the burner 2.

[0047] It should be noted that the burner 2 has an ignition electrode. When the bag dryer is working, the combustion fan is turned on to deliver combustion air to the burner 2 through the second air intake pipe 5. At the same time, the gas control valve is opened, and the gas enters the burner 2 through the first air intake pipe 4 and mixes with the combustion air. Then the ignition electrode is activated to ignite the mixture. The mixture is sprayed out from the lower end of the burner 2. After ignition, a baking flame is formed to bake the bag. If the flame detector detects that the flame is normal, the ignition electrode is turned off and the bag dryer works normally. If the flame detector detects that the flame is abnormal, the gas control valve is turned off and an alarm is issued. The bag dryer continues to work after the fault is cleared and reset.

[0048] With this configuration, when the combustion air passes through the second intake pipe 5, since the second sub-pipe 52 of the second intake pipe 5 is designed in a ring shape, the combustion air in the second sub-pipe 52 circulates once inside the shell 1 before entering the burner 2. The low-temperature combustion air passing through the second sub-pipe 52 can reduce the shell temperature and at the same time help to increase the temperature of the combustion air, thereby effectively improving the combustion effect.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the second sub-pipe 52 is fixed to the inner surface of the top wall 16. Specifically, the second sub-pipe 52 can be set on the inner surface of the top wall 16, and the installation method includes but is not limited to welding. With this setting, the low-temperature combustion air through the second sub-pipe 52 can reduce the working temperature of components such as temperature measuring thermocouples, ignition electrodes, and flame detectors above the top wall 16, which is beneficial to improving the service life of the bread dryer.

[0050] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a portion of the first intake pipe 4 extends into the burner 2. In other words, the first intake pipe 4 can extend into the burner 2. This configuration allows the gas to be directly delivered to the center of the burner 2, thereby improving the gas intake efficiency and thus enhancing the combustion effect.

[0051] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the first intake pipe 4 and the burner 2 are arranged concentrically. That is to say, the first intake pipe 4 and the burner 2 can be constructed as concentric pipes. This arrangement helps to improve the intake efficiency of the gas, thereby improving the combustion effect.

[0052] In some embodiments of the present invention, a heat insulation component is further included, which is disposed within the installation space 13 and sandwiched between the heat insulation component 3 and the housing 1. That is, the oven cover 100 is also provided with a heat insulation component, which can be made of ceramic fiber paper. This ceramic fiber paper is disposed within the installation space 13 and sandwiched between the heat insulation component 3 and the housing 1. This arrangement prevents heat loss, increases the baking temperature, and helps save energy. Furthermore, the heat insulation component also provides a certain degree of heat insulation, which helps reduce the operating temperature of the components above the housing 1.

[0053] The bread dryer according to a second aspect of the present invention includes the bread dryer cover 100 of the first aspect embodiment.

[0054] According to the embodiments of the present invention, the baking oven is provided with the baking oven cover 100 described above. The first section 21 of the burner 2 is surrounded and covered by the heat insulation member 3, which can prevent the flame emitted by the burner 2 from directly baking the nozzle position of the burner 2, thereby reducing the temperature of the burner 2 during operation, which is beneficial to extending the service life of the burner 2 and thus saving costs.
