Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mesh belt sintering furnace, in particular to a mesh belt sintering furnace humidifier and mesh belt sintering furnace. BACKGROUND

[0002] Powder metallurgy iron-based products will add part lubricant as counteracting powder wall friction and stripping in compaction forming. The lubricant is mostly organic matter composition, in the sintering process, will because high temperature leads to lubricant instantaneous a large number of gasification, extrusion gap in the part, causes product to produce surface peeling, burst phenomenon, commonly known as "popcorn phenomenon" in the industry, so need to carry out dewaxing before entering high temperature section.

[0003] The conventional dewaxing mode has gas dewaxing and electric dewaxing. The gas dewaxing can effectively solve the dewaxing problem, but because the gas dewaxing environment is high dew point environment, and there is a large amount of free carbon in the dewaxing process, and the low-carbon high-alloy product is not friendly, and the electric dewaxing mode can be used for the product.

[0004] But because electric dewaxing is slowly sublimated into gaseous state for solid lubricant, the process is very long, leads to the length requirement of dewaxing section to be very long. In actual manufacture, because of structure and site limitation, cannot make the dewaxing area very long, like this can lead to waste precious site resource, and greatly increase power consumption, improves production cost. So the electric dewaxing area is generally 1:1 length with high temperature sintering area in general design, if part product is not removed clean lubricant, then can lead to "popcorn phenomenon" in the later high temperature area. Utility model content

[0005] In order to overcome the insufficient in the prior art, the utility model provides a mesh belt sintering furnace humidifier, it can carry out humidification treatment to the protection gas that is rushed into the mesh belt sintering furnace, and pure water can react with lubricant under high temperature, greatly improves dewaxing effect, and greatly shortens the time required for dewaxing. The utility model further provides a mesh belt sintering furnace.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:

[0007] The application discloses a mesh belt sintering furnace humidifier which comprises a liquid storage container provided with a liquid storage cavity for storing liquid; the liquid storage container is provided with an air outlet pipe and an air inlet pipe; two ends of the air outlet pipe are formed into an air outlet end and an air outlet communication end, respectively; the air outlet end is used for outputting protective gas to the mesh belt sintering furnace; the air outlet communication end is used for being communicated with the liquid storage cavity of the liquid storage container; two ends of the air inlet pipe are formed into an air inlet end and an air inlet communication end, respectively; the air inlet end is used for being connected with a protective gas supply device; the air inlet communication end is used for being communicated with the liquid storage cavity of the liquid storage container; and the air inlet communication end is closer to the bottom surface of the liquid storage cavity than the air outlet communication end.

[0008] In use, the air inlet end is connected with the protective gas supply device, the air outlet end is communicated with a dewaxing section of the mesh belt sintering furnace, and pure water is stored in the liquid storage cavity of the liquid storage container; the liquid level of the pure water is higher than the air inlet communication end and is not higher than the air outlet communication end, that is, the liquid level of the pure water is between the air inlet communication end and the air outlet communication end; at this time, when the air inlet pipe inputs the protective gas into the liquid storage cavity, the protective gas is introduced into the pure water and then is output to the dewaxing section of the mesh belt sintering furnace through the air outlet pipe; since the protective gas passes through the pure water, the protective gas input to the dewaxing section of the mesh belt sintering furnace is subjected to humidification treatment, that is, the protective gas input to the dewaxing section of the mesh belt sintering furnace carries the pure water; the protective gas can provide a protective atmosphere for the dewaxing section; generally, the protective gas is nitrogen; and the pure water can significantly improve the dewaxing effect.

[0009] Specifically, the lubricant is mostly an organic substance, that is, a hydrocarbon compound, or a zinc stearate organic substance containing carbon, hydrogen, oxygen and a certain metal; in dewaxing, the pure water can react with the lubricant at about 550 DEG C to generate a reducing atmosphere which is very beneficial to the product; the chemical reaction formula is as follows:

[0010] CxHy0zM+H20→CO+CO2+H2+MO, M is a metal (such as zinc in zinc stearate);

[0011] The above technical scheme can greatly improve the dewaxing effect, greatly shorten the time required for dewaxing, and enable the protective gas carrying the pure water to raise the dewaxing temperature early.

[0012] Further, the air inlet end is farther away from the bottom surface of the liquid storage cavity than the air inlet communication end.

[0013] The above technical scheme makes the air inlet pipe more reasonable; since there is a height difference between the air inlet end and the air inlet communication end, when the pure water is higher than the air inlet communication end, the pure water can be not higher than the air inlet end, thereby avoiding that the pure water is returned to the outside through the air inlet pipe.

[0014] Further, the air inlet pipe comprises a first air inlet pipe section and a second air inlet pipe section, one end of the first air inlet pipe section is located outside the side wall of the liquid storage container and forms the air inlet end, the other end of the first air inlet pipe section penetrates the side wall of the liquid storage container and communicates with one end of the second air inlet pipe section located in the liquid storage cavity of the liquid storage container, and the other end of the second air inlet pipe section extends towards the bottom side of the liquid storage cavity and forms the air inlet communication end.

[0015] The above technical solution makes the structure of the air inlet pipe more reasonable and effectively realizes the height difference setting between the air inlet end and the air inlet communication end. Specifically, the connection between the first air inlet pipe section and the second air inlet pipe section is arc-shaped.

[0016] Further, the liquid storage container is provided with a liquid inlet pipe, two ends of the liquid inlet pipe form a liquid inlet end and a liquid inlet communication end respectively, the liquid inlet end is used for connecting with a liquid supply device, and the liquid inlet communication end communicates with the liquid storage cavity of the liquid storage container.

[0017] The above technical solution makes the mesh belt sintering furnace humidifier more reasonable, and the liquid inlet pipe can deliver pure water to the liquid storage cavity of the liquid storage container, which is more convenient.

[0018] Further, the air outlet pipe and the air inlet pipe are located on opposite sides of the liquid storage container, the liquid inlet pipe and the air outlet pipe are located on the same side of the liquid storage container, the liquid inlet pipe is arranged close to the bottom surface of the liquid storage cavity, the air outlet pipe is arranged close to the top surface of the liquid storage cavity, the first air inlet section is arranged close to the top surface of the liquid storage cavity, the position height of the first air inlet section and the air outlet pipe is substantially consistent, and the liquid inlet communication end is arranged higher than the air inlet communication end.

[0019] The above technical solution makes the arrangement of the air outlet pipe, the air inlet pipe and the liquid inlet pipe more reasonable.

[0020] Further, the liquid inlet communication end is closer to the bottom surface of the liquid storage cavity than the air outlet communication end.

[0021] The above technical solution makes the arrangement of the liquid inlet pipe more reasonable, and the process of delivering water from the liquid inlet pipe to the liquid storage cavity is more reasonable, which avoids affecting the output of the protective gas carrying pure water.

[0022] Further, the mesh belt sintering furnace humidifier comprises a flow meter, and the flow meter is used to adjust the flow of the protective gas delivered by the air inlet pipe to the liquid storage cavity.

[0023] By adopting the technical scheme, the flow meter is arranged to adjust the flow of the protective gas delivered by the air inlet pipe to the liquid storage cavity, that is, to adjust the flow of the protective gas delivered by the air outlet pipe to the dewaxing section of the mesh belt sintering furnace, the flow of the protective gas is adjusted to adjust the protective atmosphere of the dewaxing section, so that the protective atmosphere is more suitable for the actual scene, and a better atmosphere is provided for product dewaxing.

[0024] Further, the mesh belt sintering furnace humidifier comprises a heating structure for heating the liquid in the liquid storage container.

[0025] By adopting the technical scheme, the heating structure can heat the pure water in the liquid storage container, the water temperature is adjusted by adjusting the heating structure, so that the carrying ratio of the pure water in the output protective gas can be adjusted, the amount of pure water participating in the reaction in the dewaxing stage is ensured to be sufficient, and the oxidation of the product surface caused by excessive pure water is avoided.

[0026] Generally, the heating structure usually heats the pure water to about 60 to 80 degrees Celsius, and cannot make the pure water boil. Boiling water will cause excessive steam to enter the furnace of the dewaxing section.

[0027] Further, the heating structure is arranged close to the bottom surface of the liquid storage cavity.

[0028] By adopting the technical scheme, the arrangement of the heating structure is more reasonable, and the pure water in the liquid storage cavity can be well heated.

[0029] Further, the heating structure comprises an electric heating tube and a support plate, the liquid storage container is provided with a heating mounting portion, the heating mounting portion has a mounting accommodating cavity, the mounting accommodating cavity is in communication with the liquid storage cavity, one end of the heating mounting portion away from the liquid storage cavity is formed into a mounting opening, the support plate is arranged at the mounting opening and fixed, the electric heating tube is mounted on the support plate and extends to the liquid storage cavity side.

[0030] By adopting the technical scheme, the heating structure is more reasonable, and stable and reliable installation of the heating structure can be realized.

[0031] Further, the support plate is sealingly arranged with the outer periphery of the mounting opening.

[0032] By adopting the technical scheme, the support plate is sealingly arranged with the outer periphery of the mounting opening, so that the pure water in the liquid storage cavity can be prevented from flowing out through the gap between the support plate and the outer periphery of the mounting opening.

[0033] Further, the heating mounting portion is protruded radially outward at the outside of the mounting port to form a support plate mounting portion, the support plate cover is arranged at the mounting port and is fixed with the support plate mounting portion through the first fastener, a first sealing ring is arranged between the support plate and the support plate mounting portion, and the first sealing ring is closer to the mounting port side than the connection position of the support plate mounting portion and the first fastener, that is, the first sealing ring is located at the inside of the connection position of the support plate mounting portion and the first fastener.

[0034] By adopting the technical scheme, the stable and reliable installation of the support plate is realized, and the sealing effect between the support plate and the support plate mounting portion is ensured, that is, the sealing effect between the support plate and the outer periphery of the mounting port is ensured.

[0035] Specifically, the first fastener is a bolt.

[0036] Further, the liquid storage container is provided with a liquid outlet pipe, two ends of the liquid outlet pipe are formed into a liquid outlet end and a liquid outlet communication end respectively, the liquid outlet end is used for communicating with the outside, and the liquid outlet communication end communicates with the liquid storage cavity of the liquid storage container.

[0037] By adopting the technical scheme, the mesh belt sintering furnace humidifier is more reasonable, the pure water in the liquid storage cavity of the liquid storage container can be discharged through the liquid outlet pipe to meet the use scene, for example, when the mesh belt sintering furnace humidifier is not used for a long time, the remaining pure water in the liquid storage cavity can be discharged to avoid the phenomenon of deterioration of the pure water when not used for a long time, thereby affecting the subsequent use; when the inside of the liquid storage cavity needs to be maintained, the remaining pure water in the liquid storage cavity can be discharged to facilitate the maintenance.

[0038] Further, the liquid outlet communication end is located at the bottom surface of the liquid storage cavity, and the liquid outlet pipe is provided with a control switch for controlling whether the liquid outlet pipe communicates with the outside.

[0039] By adopting the technical scheme, the liquid outlet pipe is more reasonable; since the liquid outlet communication end is located at the bottom surface of the liquid storage cavity, the pure water in the liquid storage cavity can be discharged more completely when the pure water in the liquid storage cavity is discharged through the liquid outlet pipe, that is, the pure water in the liquid storage cavity can be discharged as much as possible.

[0040] The control switch can control the liquid discharge of the liquid outlet pipe, when the mesh belt sintering furnace humidifier is normally used, the control switch is turned off, so that the liquid outlet pipe does not communicate with the outside, thereby preventing the pure water in the liquid storage cavity from flowing out; when the mesh belt sintering furnace humidifier discharges liquid, the control switch is turned on, so that the liquid outlet pipe communicates with the outside, thereby making the pure water in the liquid storage cavity flow out.

[0041] Further, the mesh belt sintering furnace humidifier comprises a liquid level detection structure for detecting the liquid level in the liquid storage cavity.

[0042] The above technical solution makes the mesh belt sintering furnace humidifier more reasonable. The liquid level detection structure can detect the liquid level in the liquid storage cavity. Therefore, the liquid level of pure water can be prevented from being lower than the air inlet communication end, i.e., the liquid level of pure water is ensured to be higher than the air inlet communication end, and the liquid level of pure water can be prevented from being higher than the air outlet communication end, i.e., the liquid level of pure water is ensured to be lower than the air outlet communication end, so as to ensure that the liquid level of pure water in the liquid storage container is within a reasonable working range, and the mesh belt sintering furnace humidifier can be stably and reliably operated.

[0043] Specifically, the liquid level detection structure is of an observation type. When an operator observes that the liquid level detection structure indicates that the liquid level of pure water is lower than the air inlet communication end, the operator can timely inject water into the liquid storage cavity. When the operator observes that the liquid level detection structure indicates that the liquid level of pure water is higher than the air outlet communication end, the operator can timely discharge the pure water in the liquid storage cavity. In a serious case, the equipment and products need to be detected after shutdown.

[0044] Further, the liquid level detection structure comprises a liquid level detection shell and a float. The liquid level detection shell has a float accommodating cavity extending along the height direction thereof. The liquid level detection shell is mounted to the side wall of the liquid storage container, and at least the bottom of the float accommodating cavity is in communication with the liquid storage cavity. The float is arranged in the float accommodating cavity. At least part of the liquid level detection shell is formed as a visible part through which the position of the float in the float accommodating cavity can be observed, and the visible part extends along the extension direction of the float accommodating cavity.

[0045] The above technical solution makes the liquid level detection structure more reasonable. Since at least the bottom of the float accommodating cavity is in communication with the liquid storage cavity, the liquid level in the float accommodating cavity is equivalent to the liquid level in the liquid storage cavity. The float is arranged in the float accommodating cavity and rises and falls along the float accommodating cavity along with the liquid level. The float is arranged to facilitate the operator to observe the current liquid level through the visible part.

[0046] Specifically, the liquid level detection shell comprises a liquid level detection shell body and a liquid level detection shell cover, the rear side of the liquid level detection shell body is connected with the side wall of the liquid storage container, the liquid level detection shell body has the float accommodating cavity, the front side of the liquid level detection shell body is open to form a float mounting opening, and the liquid level detection shell cover covers the front side of the liquid level detection shell body and can cover the float mounting opening; and the liquid level detection shell cover is provided with the visible part.

[0047] The liquid level detection shell cover is sealingly arranged with the outer periphery of the float mounting opening, that is, a third sealing member is arranged between the liquid level detection shell cover and the outer periphery of the float mounting opening of the front side of the liquid level detection shell body.

[0048] The liquid level detection shell cover and the liquid level detection shell body are fixed by a third fastener, and specifically, the third fastener is a bolt.

[0049] The above technical solution facilitates the installation of the liquid level detection structure. Specifically, during installation, the float can be first mounted into the float accommodating cavity in the liquid level detection shell body, the liquid level detection shell cover is then arranged on the front side of the liquid level detection shell body, and of course, the third sealing member needs to be arranged between the liquid level detection shell cover and the liquid level detection shell body during the arrangement of the liquid level detection shell cover on the front side of the liquid level detection shell body. Finally, the third fastener is used to fix the liquid level detection shell cover on the liquid level detection shell body, and then the liquid level detection structure can be integrally installed on the liquid storage container.

[0050] Further, the distance from the bottom of the visible part to the bottom surface of the accommodating cavity is greater than or equal to the distance from the air inlet communication end to the bottom surface of the accommodating cavity; the distance from the top of the visible part to the bottom surface of the accommodating cavity is less than or equal to the distance from the air outlet communication end to the bottom surface of the accommodating cavity; and the distance from the top of the visible part to the bottom surface of the accommodating cavity is less than or equal to the distance from the air inlet end to the bottom surface of the accommodating cavity.

[0051] The above technical solution makes the visible part more reasonable. Since the distance from the bottom of the visible part to the bottom surface of the accommodating cavity is greater than or equal to the distance from the air inlet communication end to the bottom surface of the accommodating cavity, as long as the float is observed in the visible part, it indicates that the liquid level of the pure water in the liquid storage container is higher than the air inlet communication end.

[0052] Since the distance from the top of the visible part to the bottom surface of the accommodating cavity is less than or equal to the distance from the air outlet communication end to the bottom surface of the accommodating cavity, as long as the float is not in the state of the top of the visible part, it indicates that the liquid level of the pure water in the liquid storage container is not higher than the air outlet communication end.

[0053] Since the distance from the top of the visible part to the bottom of the containing cavity is less than or equal to the distance from the air inlet end to the bottom of the containing cavity, as long as the float is not in the state of the top of the visible part, it indicates that the liquid level of the pure water in the liquid storage cavity is not higher than the air inlet end.

[0054] That is, as long as the float is between the two ends of the visible part, it indicates that the liquid level of the pure water in the liquid storage cavity is in a reasonable position; the above technical solution is convenient for the operator to observe and is rationally designed.

[0055] Further, the liquid storage container comprises a liquid storage container body and a container cover body, the liquid storage container body has the liquid storage cavity, and the top of the liquid storage container body is open to form a container opening, and the container cover body can cover the container opening.

[0056] The above technical solution makes the liquid storage container more reasonable. When the operator needs to maintain the mesh belt sintering furnace humidifier, the container cover body is only needed to be detached from the top of the liquid storage container body, at this time, the liquid storage cavity is exposed through the container opening, and the operator can maintain the inside of the liquid storage cavity. Of course, if the pure water in the liquid storage cavity needs to be discharged, only the drainage operation through the liquid outlet pipe is needed.

[0057] Further, the container cover body is sealingly arranged with the outer periphery of the container opening.

[0058] The above technical solution makes the connection between the container cover body and the outer periphery of the container opening more reasonable; effectively avoids the leakage of the protective gas through the gap between the container cover body and the outer periphery of the container opening.

[0059] Further, the liquid storage container body is radially outwardly protruded outside the container opening to form a cover body mounting portion, the container cover body is arranged at the container opening and is fixed with the cover body mounting portion through a second fastener, and a second sealing ring is arranged between the container cover body and the cover body mounting portion.

[0060] The above technical solution effectively realizes the stable and reliable installation of the container cover body and ensures the sealing effect between the container cover body and the outer periphery of the container opening.

[0061] Specifically, the second fastener adopts a bolt.

[0062] Further, the mesh belt sintering furnace humidifier comprises support feet for supporting the liquid storage container, the support feet are provided in plurality, and the plurality of support feet are arranged at intervals around the axis of the liquid storage container.

[0063] With the technical scheme, the mesh belt sintering furnace humidifier is more reasonable, the support feet are arranged to facilitate the mesh belt sintering furnace humidifier to stand stably, facilitate the arrangement of the drain pipe, and make the visible part of the liquid level detection structure be in a height range convenient for an operator to observe.

[0064] Specifically, the support feet include support legs and a foot bottom, one end of the support leg is connected with the bottom surface of the liquid storage container and is arranged close to the edge of the bottom surface of the liquid storage container, the other end extends away from the liquid storage container and is connected with the foot bottom, and the foot bottom is in a plate structure; three support feet are arranged at equal intervals around the axis of the liquid storage container.

[0065] A mesh belt sintering furnace includes the mesh belt sintering furnace humidifier, and the gas outlet end of the mesh belt sintering furnace humidifier is connected with a dewaxing section of the mesh belt sintering furnace.

[0066] With the technical scheme, the mesh belt sintering furnace humidifier is arranged, so that the protective gas delivered to the dewaxing section of the mesh belt sintering furnace carries pure water, the dewaxing effect can be greatly improved, the time required for dewaxing can be greatly shortened, and the dewaxing temperature can be raised early by the protective gas carrying pure water.

[0067] Compared with the prior art, the mesh belt sintering furnace humidifier and the mesh belt sintering furnace have the following beneficial effects:

[0068] (1) The mesh belt sintering furnace humidifier and the mesh belt sintering furnace can humidify the protective gas injected into the mesh belt sintering furnace, and the pure water can react with the lubricant at high temperature, greatly improving the dewaxing effect and greatly shortening the time required for dewaxing.

[0099] The technical scheme makes the liquid inlet pipe 4 more reasonable, and the process of the liquid inlet pipe 4 delivering pure water to the liquid storage cavity 101 is more reasonable, thereby avoiding affecting the output of the protective gas carrying the pure water.

[0101] The technical scheme makes the liquid inlet pipe 4 more reasonable, and the process of the liquid inlet pipe 4 delivering pure water to the liquid storage cavity 101 is more reasonable, thereby avoiding affecting the output of the protective gas carrying the pure water.

[0102] Generally, the heating structure 6 heats the pure water to about 60 to 80 degrees Celsius, and cannot make the pure water boil. Boiling water will cause excessive steam to enter the furnace of the dewaxing section.

[0104] The technical scheme makes the liquid inlet pipe 4 more reasonable, and the process of the liquid inlet pipe 4 delivering pure water to the liquid storage cavity 101 is more reasonable, thereby avoiding affecting the output of the protective gas carrying the pure water.

[0105] Further, the heating structure 6 comprises an electric heating tube 601 and a support plate 602. The liquid storage container 1 is provided with a heating mounting portion 102, the heating mounting portion 102 has a mounting accommodating cavity 102-1, the mounting accommodating cavity 102-1 is in communication with the liquid storage cavity 101, one end of the heating mounting portion 102 away from the liquid storage cavity 101 is formed into a mounting opening 102-2, the support plate 602 is arranged at the mounting opening 102-2 and fixed, the electric heating tube 601 is arranged on the support plate 602 and extends to the liquid storage cavity 101.

[0106] The heating structure 6 is more reasonable and can be stably and reliably installed.

[0107] Further, the support plate 602 is sealingly arranged at the outer periphery of the mounting port 102-2.

[0108] The support plate 602 is sealingly arranged at the outer periphery of the mounting port 102-2, which can prevent pure water in the liquid storage cavity 101 from flowing out through the gap between the support plate 602 and the outer periphery of the mounting port 102-2.

[0109] Further, the heating mounting portion 102 is radially outwardly protruded at the outer side of the mounting port 102-2 to form a support plate mounting portion 102-3, the support plate 602 is arranged at the mounting port 102-2 and fixed to the support plate mounting portion 102-3 by the first fastener 7, a first sealing ring 8 is arranged between the support plate 602 and the support plate mounting portion 102-3, and the first sealing ring 8 is closer to the mounting port 102-2 side than the connection position of the support plate mounting portion 102-3 and the first fastener 7, that is, the first sealing ring 8 is located on the inner side of the connection position of the support plate mounting portion 102-3 and the first fastener 7.

[0110] The above technical solution effectively realizes stable and reliable installation of the support plate 602 and ensures the sealing effect between the support plate 602 and the support plate mounting portion 102-3, that is, the sealing effect between the support plate 602 and the outer periphery of the mounting port 102-2.

[0111] Specifically, the first fastener 7 is a bolt.

[0112] Further, the liquid storage container 1 is provided with a liquid outlet pipe 9, both ends of the liquid outlet pipe 9 are formed into a liquid outlet end 901 and a liquid outlet communication end 902, the liquid outlet end 901 is used for communication with the outside, and the liquid outlet communication end 902 is in communication with the liquid storage cavity 101 of the liquid storage container 1.

[0113] The above technical solution makes the mesh belt sintering furnace humidifier more reasonable, and the pure water in the liquid storage cavity 101 of the liquid storage container 1 can be discharged through the liquid outlet pipe 9 to meet the use scene, for example, when the mesh belt sintering furnace humidifier is not used for a long time, the remaining pure water in the liquid storage cavity 101 can be discharged to avoid the phenomenon of deterioration of the pure water when not used for a long time, thereby affecting the subsequent use; when the inside of the liquid storage cavity 101 needs to be maintained, the remaining pure water in the liquid storage cavity 101 can be discharged to facilitate maintenance.

[0114] Further, the liquid outlet communication end 902 is located at the bottom surface of the liquid storage cavity 101, and the liquid outlet pipe 9 is provided with a control switch for controlling whether it is in communication with the outside.

[0115] The above technical solution makes the liquid outlet pipe 9 more reasonable.

[0116] The control switch can control the liquid outlet of the liquid outlet pipe 9. When the mesh belt sintering furnace humidifier is in normal use, the control switch is turned off, so that the liquid outlet pipe 9 is not in communication with the outside, thereby preventing the pure water in the liquid storage cavity 101 from flowing out. When the mesh belt sintering furnace humidifier is discharging, the control switch is turned on, so that the liquid outlet pipe 9 is in communication with the outside, thereby causing the pure water in the liquid storage cavity 101 to flow out.

[0117] Further, the mesh belt sintering furnace humidifier comprises a liquid level detection structure 10 for detecting the liquid level in the liquid storage cavity 101.

[0118] The above technical solution makes the mesh belt sintering furnace humidifier more reasonable. The liquid level detection structure 10 can detect the liquid level in the liquid storage cavity 101, so that the liquid level of the pure water can be prevented from being lower than the air inlet communication end 202 through the liquid level detection structure 10, that is, the liquid level of the pure water is ensured to be higher than the air inlet communication end 202, and the liquid level of the pure water can be prevented from being higher than the air outlet communication end 302, that is, the liquid level of the pure water is ensured to be lower than the air outlet communication end, thereby ensuring that the liquid level of the pure water in the liquid storage container 1 is within a reasonable working range, so that the mesh belt sintering furnace humidifier can operate stably and reliably.

[0119] Specifically, the liquid level detection structure 10 is an observation type. When the operator observes that the liquid level detection structure 10 indicates that the liquid level of the pure water is lower than the air inlet communication end 202, the operator can timely inject water into the liquid storage cavity 101. When the operator observes that the liquid level detection structure 10 indicates that the liquid level of the pure water is higher than the air outlet communication end 302, the operator can timely discharge the pure water in the liquid storage cavity 101. In a serious case, the equipment and products need to be detected after shutdown. If the water injection is realized automatically, it means that the automatic operation has an error, and the machine needs to be stopped for maintenance.

[0120] Further, the liquid level detection structure 10 comprises a liquid level detection shell 1001 and a float 1002, the liquid level detection shell 1001 has a float accommodating cavity 1001-1 extending along the height direction thereof, the liquid level detection shell 1001 is installed on the side wall of the liquid storage container 1, and at least the bottom of the float accommodating cavity 1001-1 is in communication with the liquid storage cavity 101, and the float 1002 is arranged in the float accommodating cavity 1001-1; the liquid level detection shell 1001 is at least partially formed as a visible part 1001-2 capable of observing the position of the float 1002 in the float accommodating cavity 1001-1, and the visible part 1001-2 extends along the extension direction of the float accommodating cavity 1001-1.

[0121] The above technical scheme makes the liquid level detection structure 10 more reasonable, because the float accommodating cavity 1001-1 is in communication with the liquid storage cavity 101 at least at the bottom, the liquid level in the float accommodating cavity 1001-1 is equivalent to the liquid level in the liquid storage cavity 101, and the float 1002 is located in the float accommodating cavity 1001-1 and rises and falls along the float accommodating cavity 1001-1 with the liquid level, and the float 1002 is arranged to facilitate the operator to observe through the visible part 1001-2, so as to understand the current liquid level.

[0122] Specifically, the liquid level detection shell 1001 comprises a liquid level detection shell body 1001-3 and a liquid level detection shell cover 1001-4, the rear side of the liquid level detection shell body 1001-3 is connected with the side wall of the liquid storage container 1, and the liquid level detection shell body 1001-3 has the float accommodating cavity 1001-1, the front side of the liquid level detection shell body 1001-3 is open to form a float mounting opening 1001-31, and the liquid level detection shell cover 1001-4 is arranged on the front side of the liquid level detection shell body 1001-3 and can cover the float mounting opening 1001-31; and the liquid level detection shell cover 1001-4 is provided with the visible part 1001-2.

[0125] With the above technical solution, the installation of the liquid level detection structure 10 is facilitated. Specifically, during installation, the float 1002 can be first installed into the float accommodating cavity 1001-1 in the liquid level detection shell body 1001-3, the liquid level detection shell cover 1001-4 is then arranged on the front side of the liquid level detection shell body 1001-3, and of course, the third sealing member 1001-5 needs to be padded between the two during the arrangement of the liquid level detection shell cover 1001-4 on the front side of the liquid level detection shell body 1001-3, and finally, the third fastener 1001-6 is used to fix the liquid level detection shell cover 1001-4 on the liquid level detection shell body 1001-3, and then the liquid level detection structure 10 can be integrally installed on the liquid storage container 1.

[0127] With the above technical solution, the visible part 1001-2 is more reasonable. Since the distance from the bottom of the visible part 1001-2 to the bottom surface of the accommodating cavity is greater than or equal to the distance from the air inlet communication end 202 to the bottom surface of the accommodating cavity, as long as the float 1002 is observed in the visible part 1001-2, it indicates that the liquid level of the pure water in the liquid storage cavity 101 is higher than the air inlet communication end 202.

[0128] Since the distance from the top of the visible part 1001-2 to the bottom surface of the accommodating cavity is less than or equal to the distance from the air outlet communication end 302 to the bottom surface of the accommodating cavity, as long as the float 1002 is not in the state of the top of the visible part 1001-2, it indicates that the liquid level of the pure water in the liquid storage cavity 101 is not higher than the air outlet communication end 302.

[0129] Since the distance from the top of the visible part 1001-2 to the bottom surface of the accommodating cavity is less than or equal to the distance from the air inlet end 201 to the bottom surface of the accommodating cavity, as long as the float 1002 is not in the state of the top of the visible part 1001-2, it indicates that the liquid level of the pure water in the liquid storage cavity 101 is not higher than the air inlet end 201.

[0130] That is, as long as the float 1002 is between the two ends of the visible part 1001-2, it indicates that the liquid level of the pure water in the liquid storage cavity 101 is in a reasonable position. The above technical solution is convenient for operators to observe and is reasonable in design.

[0131] Further, the liquid storage container 1 comprises a liquid storage container body 103 having the liquid storage cavity 101, and a top of the liquid storage container body 103 is open to form a container opening 103-1, and a container cover 104 capable of covering the container opening 103-1.

[0132] With the above technical solution, the liquid storage container 1 is more reasonable. When the operator needs to maintain the mesh belt sintering furnace humidifier, the container cover 104 is only needed to be detached from the top of the liquid storage container body 103. At this time, the liquid storage cavity 101 is exposed through the container opening 103-1, and the operator can maintain the inside of the liquid storage cavity 101. Of course, if the pure water in the liquid storage cavity 101 needs to be discharged, only the drainage operation through the liquid outlet pipe 9 is needed.

[0133] Further, the container cover 104 is sealingly arranged with the outer periphery of the container opening 103-1.

[0134] With the above technical solution, the connection between the container cover 104 and the outer periphery of the container opening 103-1 is more reasonable; and the protection gas is effectively prevented from leaking out through the gap between the container cover 104 and the outer periphery of the container opening 103-1.
