[0002] Quality inspection is an essential part of the production process of chemical and pharmaceutical products. Usually, samples are taken and tested at several time points, such as the beginning, middle and end of production. Nitrogen blowdown equipment is often used for testing during the testing process.

[0003] At present, the nitrogen blowdown instrument includes a pipeline and a nitrogen bottle connected to the pipeline, wherein nitrogen is stored in the nitrogen bottle. When the nitrogen blowdown instrument is in operation, the nitrogen is sprayed toward the liquid inside the sample bottle through the columnar pipeline.

[0004] However, in this method, the nitrogen cannot fully contact the liquid inside the sample bottle when it is sprayed, and the gas spray speed is fast, which can easily cause liquid splashing. Utility Model Content

[0006] To achieve the above object, the utility model provides a nitrogen blowing instrument, comprising a base, a bracket, a driving assembly and an air jet assembly, wherein the bracket is arranged on the base, and a plurality of receiving grooves are arranged on the base, and the receiving grooves are used to receive sample bottles;

The nitrogen blowpipe has a nozzle head facing the receiving tank, and the nozzle head is configured to extend into the sample bottle under the drive of the first driving member to blow nitrogen to the sample in the sample bottle.

[0009] The beneficial effects of the utility model are as follows: through the design of the jet assembly and the drive assembly, the nitrogen blowing pipe on the jet assembly can be moved under the drive of the first drive member on the drive assembly, and then extended into the sample bottle to blow nitrogen to the sample, thereby completing the nitrogen blowing process; in addition, by providing a nozzle head on the nitrogen blowing pipe, when the nitrogen is sprayed, the nozzle head with a shower structure similar to that of a shower head can increase the contact area between the nitrogen and the sample liquid when the nitrogen is sprayed, thereby reducing the nitrogen blowing time and saving nitrogen, and preventing the liquid in the nitrogen blowing bottle from splashing out or spraying onto the nitrogen blowing pipe due to excessive airflow, thereby causing losses.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] In some optional embodiments, the driving assembly further includes a controller, which is disposed on the base and is used to control the first driving member so that the first driving member drives the mounting frame to move along the length direction of the bracket.

[0012] It should be noted that the controller controls the first driving member to drive the mounting frame to move along the length direction of the bracket, thereby driving the plurality of nitrogen blowing tubes disposed on the mounting frame to move along the length direction of the bracket.

[0013] In some optional embodiments, the shape of the spray head is trumpet-shaped.

[0014] It should be noted that small holes are provided at the bottom or side of the nozzle head to allow gas to flow out from different directions, thereby increasing the contact area between gas and liquid and accelerating the drying efficiency.

[0017] In some optional embodiments, the jet assembly further includes a mounting member, wherein the mounting member has a hollow cavity;

[0018] The first end of the mounting piece is threadedly connected to the end of the pipeline, and the second end of the mounting piece is threadedly connected to the end of the nitrogen blow pipe to connect the pipeline and the nitrogen blow pipe.

The external threaded section of the pipeline is threadedly connected to the internal threaded section of the mounting piece, and the external threaded section of the nitrogen blowpipe is threadedly connected to the internal threaded section of the mounting piece.

[0021] It should be noted that the internal thread section in the mounting piece matches the external thread section of the pipeline and the external thread section of the nitrogen blowpipe respectively, so as to ensure the connection among the mounting piece, the pipeline and the nitrogen blowpipe.

[0027] It should be noted that the liquid level detector can detect the liquid sample inside the sample bottle, so that the subsequent controller can control the movement of the second driving member, the second driving member drives the first driving member to move, and the first driving member drives the nitrogen blowpipe to automatically move downward under the action of the drive, and nitrogen blows within a certain preset distance from the liquid level of the liquid sample inside the sample bottle, and at the same time, an alarm is promptly issued when there is no liquid inside the sample bottle.

[0028] In some optional embodiments, the first driving member is a lead screw, the mounting frame has a threaded hole matching the lead screw, and the mounting frame sleeve is used to drive the mounting frame to move axially along the lead screw when the lead screw rotates around its own axis.

[0029] It should be noted that the thread on the lead screw matches the threaded hole in the mounting frame, and when the lead screw rotates, it drives the mounting frame to move up and down along the length of the lead screw. This arrangement ensures that the mounting frame can be moved closer to or farther from the receiving slot, so that the nitrogen blowing tube on the mounting frame can be moved closer to or farther from the receiving slot, thereby completing nitrogen blowing.

[0075] At present, the nitrogen blowing instrument includes a pipeline and a nitrogen bottle connected to the pipeline, wherein the nitrogen is stored in the nitrogen bottle. When the nitrogen blowing instrument is in operation, the nitrogen is sprayed toward the liquid inside the sample bottle through the columnar pipeline. However, in this way, the nitrogen cannot fully contact the liquid inside the sample bottle when it is sprayed, and the gas spray speed is too fast to easily cause liquid splashing.

[0076] In order to overcome the defects in the prior art, the nitrogen blowing instrument provided by the utility model, through the design of the jet component and the drive component, the nitrogen blowing pipe on the jet component can be moved under the drive of the first drive member on the drive component, and then extended into the sample bottle to blow nitrogen to the sample, thereby completing the nitrogen blowing process; in addition, by providing a nozzle head on the nitrogen blowing pipe, when the nitrogen is sprayed, the nozzle head with a shower structure similar to that of a shower head can increase the contact area between the nitrogen and the sample liquid when the nitrogen is sprayed, thereby reducing the nitrogen blowing time and saving nitrogen, and preventing the liquid in the nitrogen blowing bottle from splashing out or spraying onto the nitrogen blowing pipe due to excessive airflow, thereby causing losses.

[0077] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0078] Figure 1 A schematic diagram of the structure of a nitrogen blowdown apparatus provided in an embodiment of the present application, Figure 2 A schematic diagram of the state between the nitrogen blowpipe and the sample bottle in the nitrogen blowpipe apparatus provided in an embodiment of the present application.

[0079] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a nitrogen blowing instrument 100, including a base 110, a bracket 120, a driving assembly 130 and an air injection assembly 140, the bracket 120 is arranged on the base 110, and a plurality of receiving grooves 171 are provided on the base 110, and the receiving grooves 171 are used to receive sample bottles 200;

[0080] In some embodiments, the base 110 may be a metal piece, and its material may include one or more of copper, iron, aluminum, tin, and lead. The material of the casting mold may be one of sand, metal, or ceramic.

[0081] In other examples, the base 110 may also be made of plastic. During injection molding, molten plastic is injected into a plastic product mold under pressure, and cooled and molded to obtain the desired plastic part.

[0082] It should be noted that the base 110 may also be made of transparent polymer materials such as polycarbonate to facilitate observation of the internal conditions.

[0083] The jet assembly 140 includes a mounting frame 141 and a plurality of nitrogen blowpipes 142 disposed on the mounting frame 141 , and the mounting frame 141 is movably disposed on the bracket 120 ;

[0084] It should be noted that the bracket 120 is provided to improve the stability of the installation and movement of the jet assembly 140 .

[0085] In some embodiments, the bracket 120 and the base 110 may be installed in a detachable or fixed connection manner, for example, a bolt or a snap connection manner.

[0086] In some examples, the bracket 120 may be a metal member, and its material may include one or more of copper, iron, aluminum, tin, and lead.

[0087] In other embodiments, the bracket 120 may be a hard plastic part.

[0088] Exemplarily, the bracket 120 may be a hard plastic part made of polyoxymethylene.

[0089] The driving assembly 130 includes a first driving member 131, a connecting end of which is arranged on the bracket 120, the first driving member 131 has a driving end connected to the mounting frame 141, and is used to drive the mounting frame 141 to approach or move away from the receiving groove 171, the nitrogen blow pipe 142 has a nozzle head 1421 facing the receiving groove 171, and the nozzle head 1421 is configured to extend into the sample bottle 200 under the drive of the first driving member 131 to blow nitrogen to the sample in the sample bottle 200.

[0090] It should be noted that the working principle of the nitrogen blowdown apparatus 100 is: increasing the surrounding air flow and temperature can accelerate evaporation. Nitrogen is an inactive gas that can isolate oxygen and prevent oxidation. The nitrogen blowdown apparatus 100 uses the rapid flow of nitrogen to break the gas-liquid equilibrium above the liquid, thereby accelerating the evaporation of the liquid; and increases the temperature by dry heating or water bath heating (the boiling point of the target is generally higher than that of the solvent), thereby achieving the purpose of concentration.

[0091] It should be noted that the multiple nitrogen blowpipes 142 correspond to the multiple containing tanks 171 one by one. The nitrogen blowpipes 142 contain nitrogen gas for blowing nitrogen into the sample in the sample bottle 200 so that the sample can be concentrated for the next quality inspection.

[0092] In some embodiments, the bracket 120 is further provided with a second driving member 132, which can be a motor for driving the first driving member 131, and then the first driving member 131 drives the mounting frame 141 to move up or down, that is, close to the receiving groove 171 or away from the receiving groove 171.

[0093] In addition, it should be noted that the bottom of the nitrogen blowpipe 142 has a nozzle head 1421, which is used to atomize the nitrogen blowpipe 142, or change the trajectory of the nitrogen gas spraying inside the nitrogen blowpipe 142, so that when the nitrogen gas is sprayed, the nozzle head 1421 with a shower structure can increase the contact area between the nitrogen gas and the sample liquid when spraying, reduce the nitrogen blowing time and save nitrogen, and avoid the possibility that the liquid in the nitrogen blow bottle may splash out or spray onto the nitrogen blowpipe 142 due to excessive airflow, causing losses.

[0094] In some embodiments, the nozzle head 1421 may be an atomizing nozzle, and the specific embodiments of the present application are not limited herein.

[0095] Through the above arrangement, that is, through the design of the jet assembly 140 and the drive assembly 130, the nitrogen blowing pipe 142 on the jet assembly 140 can be moved under the drive of the first drive member 131 on the drive assembly 130, and then extended into the sample bottle 200 to blow nitrogen to the sample, thereby completing the nitrogen blowing process; in addition, by providing a nozzle head 1421 on the nitrogen blowing pipe 142, when the nitrogen is sprayed, the nozzle head 1421 similar to a shower structure can increase the contact area between the nitrogen and the sample liquid when the nitrogen is sprayed, thereby reducing the nitrogen blowing time and saving nitrogen, and avoiding the possibility that the liquid in the nitrogen blowing bottle may splash out or spray onto the nitrogen blowing pipe 142 due to excessive airflow, causing losses.

[0096] In some optional embodiments, the driving assembly 130 further includes a controller 133 , which is disposed on the base 110 , and is configured to control the first driving member 131 so that the first driving member 131 drives the mounting frame 141 to move along the length direction of the bracket 120 .

[0097] It should be noted that the controller 133 controls the first driving member 131 to drive the mounting frame 141 to move along the length direction of the bracket 120 , thereby driving the plurality of nitrogen blowpipes 142 disposed on the mounting frame 141 to move along the length direction of the bracket 120 .

[0098] Figure 3 This is a schematic diagram of the structure of a nozzle head in a nitrogen blowing apparatus provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the structure of another nozzle head in the nitrogen blowing instrument provided in the embodiment of the present application. Figure 5 A schematic diagram of the structure of another nozzle head in the nitrogen blowing apparatus provided in an embodiment of the present application.

[0099] like Figures 1 to 5 As shown, in some optional embodiments, the nozzle head 1421 is shaped like a trumpet.

[0100] In some embodiments, the cross section of the shower head 1421 may also be a parallelogram or an S-shape.

[0101] The nozzle head 1421 has a nozzle, wherein an axis of the nozzle and an axis of the nitrogen blowing tube 142 form an included angle.

[0102] It should be noted that such a setting allows the gas to flow out from different directions, increasing the contact area between gas and liquid and accelerating the efficiency of drying.

[0103] In some embodiments, the nitrogen blowpipe 142 can be replaced with a different material and structure, such as replacing it with a polymer material to blow away corrosive liquids.

[0104] In some embodiments, the nozzle head 1421 is integrally formed with the nitrogen blowpipe 142, which can not only improve the connection strength between the nozzle head 1421 and the nitrogen blowpipe 142, but also realize seamless connection between the nozzle head 1421 and the nitrogen blowpipe 142, thereby reducing the risk of cracking at the connection position between the nozzle head 1421 and the nitrogen blowpipe 142. Further, the risk of the nozzle head 1421 falling due to excessive pressure when the nitrogen is sprayed out through the nozzle head 1421 can be avoided.

[0105] It should be noted that, in some embodiments, the nozzle head 1421 and the nitrogen blow pipe 142 are connected in an integrated manner, and in other embodiments, the nozzle head 1421 and the nitrogen blow pipe 142 can also be connected in other ways. As long as the connection method can fix the nozzle head 1421 and the nitrogen blow pipe 142, the purpose of this embodiment can be achieved. Here, there is no restriction on the connection method between the nozzle head 1421 and the nitrogen blow pipe 142.

[0106] Figure 6 This is a schematic structural diagram of the first perspective of the jet assembly in the nitrogen blowdown apparatus provided in the embodiment of the present application, Figure 7 A schematic structural diagram of a second perspective of the jet assembly in the nitrogen blowdown apparatus provided in an embodiment of the present application.

[0107] like Figures 1 to 7As shown, in some optional embodiments, the jet assembly 140 further includes a nitrogen storage box and a pipeline 143 . The nitrogen storage box is used to store nitrogen. The nitrogen storage box has an outlet, and the outlet is connected to the air inlet of the nitrogen blowpipe 142 through the pipeline 143 .

[0108] It should be noted that the design of the pipeline 143 facilitates the filling of the nitrogen in the nitrogen storage box into the nitrogen blow pipe 142, so that the connection between the gas outlet of the nitrogen storage box and the gas inlet of the nitrogen blow pipe 142 is smoother and more stable.

[0109] In some embodiments, the gas outlet of the nitrogen storage box and the pipeline 143 may be installed in a detachable or fixed connection manner, for example, a bolt or a snap connection manner.

[0110] Such a design can realize the installation and disassembly of the pipeline 143 and the nitrogen storage box, and then it can be disassembled and maintained at a later stage.

[0111] In some embodiments, the air inlet of the nitrogen blowpipe 142 and the pipeline 143 may be installed in a detachable or fixed connection manner, for example, a bolt or a snap connection manner.

[0112] Such a design can realize the installation and disassembly of the pipeline 143 and the nitrogen blowpipe 142, and then they can be disassembled and maintained at a later stage.

[0113] In some embodiments, the jet assembly 140 further includes a valve 144 , which is disposed on the pipeline 143 and can control the flow rate of nitrogen entering the nitrogen blowpipe 142 .

[0114] like Figures 1 to 7 As shown, in some optional embodiments, the jet assembly 140 further includes a mounting member 145, and the mounting member 145 has a hollow cavity;

[0115] The first end of the mounting member 145 is threadedly connected to the end of the pipeline 143 , and the second end of the mounting member 145 is threadedly connected to the end of the nitrogen blowing pipe 142 to connect the pipeline 143 and the nitrogen blowing pipe 142 .

[0116] It should be noted that the installation member 145 is provided to improve the stability of the connection between the pipeline 143 and the nitrogen blowpipe 142 , and can match pipelines 143 and nitrogen blowpipes 142 of different sizes.

[0117] In addition, the first end of the mounting member 145 is threadedly connected to the end of the pipeline 143, and the second end of the mounting member 145 is threadedly connected to the end of the nitrogen blowpipe 142. This connection method can reduce costs while ensuring the stability of the pipeline 143 and the nitrogen blowpipe 142.

[0118] In addition, it should be noted that, generally, the pipe diameters of the pipeline 143 and the nitrogen blowpipe 142 are different. Therefore, by providing a mounting member 145 to match the pipes 143 and the nitrogen blowpipe 142 of different sizes, the connection between the two is more stable, and at the same time, the problem of nitrogen leakage at the connection between the two can be avoided.

[0119] like Figures 1 to 7 As shown, in some optional embodiments, the mounting member 145 has an internal threaded section, and the ends of the pipeline 143 and the nitrogen blowpipe 142 both have external threaded sections. The external threaded section of the pipeline 143 is threadedly connected to the internal threaded section of the mounting member 145, and the external threaded section of the nitrogen blowpipe 142 is threadedly connected to the internal threaded section of the mounting member 145.

[0120] It should be noted that the internal thread section of the mounting member 145 matches the external thread section of the pipeline 143 and the external thread section of the nitrogen blowpipe 142 to ensure the connection among the mounting member 145 , the pipeline 143 and the nitrogen blowpipe 142 .

[0121] In some embodiments, the mounting frame 141 includes a first mounting frame 1411 , and an angle is formed between an extending direction of the first mounting frame 1411 and a length direction of the nitrogen blowpipe 142 .

[0122] In addition, it should be noted that the pipeline 143 and the nitrogen blowpipe 142 can be located on opposite sides of the first mounting frame 1411, respectively. Such a setting is mainly to make the pipeline 143 better connected with the nitrogen storage box, save space, and improve the overall aesthetics.

[0123] In some embodiments, the mounting frame 141 includes a first mounting frame 1411 and a second mounting frame 1412 , wherein the first mounting frame 1411 and the second mounting frame 1412 are arranged perpendicular to each other, the second mounting frame 1412 is movably connected to the first driving member 131 , and a plurality of nitrogen blowpipes 142 are arranged on the first mounting frame 1411 at intervals.

[0124] In some embodiments, the first mounting frame 1411 and the second mounting frame 1412 may both be plate-like structures.

[0125] It should be noted that the first mounting frame 1411 and the second mounting frame 1412 are integrally formed, which can ensure that the first mounting frame 1411 and the second mounting frame 1412 are integrally formed and manufactured and are inseparable structures. On the one hand, the number of parts used can be reduced, the difficulty of assembly and the requirements for assembly accuracy can be reduced, and the process of welding and connecting the first mounting frame 1411 and the second mounting frame 1412 is omitted, thereby improving assembly efficiency.

[0126] On the other hand, the overall rigidity of the mounting frame 141 can be improved, the possibility of loosening between the first mounting frame 1411 and the second mounting frame 1412 can be reduced, and the structural strength is relatively high.

[0127] like Figures 1 to 7 As shown, in some optional embodiments, a heating assembly 150 is further included, and the heating assembly 150 includes a first heating element 151 and a second heating element 152;

[0128] The first heating element 151 is sleeved on the nitrogen blowing tube 142 and is used to heat the tube wall of the nitrogen blowing tube 142 . The second heating element 152 is disposed at the bottom of the containing groove 171 to heat the sample bottle 200 .

[0129] It should be noted that the first heating element 151 is sleeved on the nitrogen blowing tube 142 and is used to heat the tube wall of the nitrogen blowing tube 142, thereby heating the nitrogen in the nitrogen blowing tube 142. The design of the first heating element 151 can adjust the temperature of the blown nitrogen, and the nitrogen blowing effect will be better with high temperature nitrogen, which saves nitrogen blowing time and nitrogen usage.

[0130] In some embodiments, the first heating element 151 may be an electric heating jacket.

[0131] In some embodiments, the first heating element 151 can be disposed on the mounting frame 141 and sleeved on the outer circumference of the nitrogen blowpipe 142 , which can ensure the stability of the installation of the first heating element 151 .

[0132] Specifically, the first heating element 151 can be set on the first mounting frame 1411 by screws and is located at the second wall surface of the first mounting frame 1411.

[0133] It should be noted that the second heating element 152 heats the containing tank 171 , and further heats the sample in the sample bottle 200 , thus saving nitrogen blowing time.

[0134] In some embodiments, there can be at least two second heating elements 152, and at least two of them can heat different receiving tanks 171 respectively. The heating temperature and heating time are controllable, so that different receiving tanks 171 can have different temperatures inside, which can meet the simultaneous use of different samples and increase the utilization rate of the nitrogen blowdown instrument 100.

[0135] In some optional embodiments, such as Figures 1 to 7 As shown, it also includes a liquid level detector 160, which is disposed on the mounting frame 141 and is electrically connected to the first driving member 131. The liquid level detector 160 is used to detect the height of the sample in the sample bottle 200;

[0136] The first driving member 131 is configured to drive the nitrogen blowpipe 142 to move according to the height of the sample in the sample bottle 200 detected by the liquid level detector 160, so that the distance between the spray head 1421 and the sample in the sample bottle 200 is within a preset distance range.

[0137] It should be noted that the liquid level detector 160 can detect the liquid sample inside the sample bottle 200, so that the subsequent controller 133 can control the movement of the second driving member 132, and the second driving member 132 drives the first driving member 131 to move. Under the action of the drive, the first driving member 131 drives the nitrogen blowpipe 142 to automatically move downward, and nitrogen blows within a certain preset distance from the liquid level of the liquid sample inside the sample bottle 200, and at the same time, an alarm is promptly issued when there is no liquid inside the sample bottle 200.

[0138] In addition, it should be noted that the range of the preset distance can be adjusted according to actual conditions, and no further restrictions are given here.

[0139] In some optional embodiments, the first driving member 131 is a lead screw, and the mounting frame 141 has a threaded hole matching the lead screw. The mounting frame 141 is used to drive the mounting frame 141 to move axially along the lead screw when the lead screw rotates around its own axis.

[0140] It should be noted that the thread on the lead screw matches the threaded hole in the mounting frame 141. When the lead screw rotates, it drives the mounting frame 141 to move up and down along the length direction of the lead screw. This arrangement ensures that the mounting frame 141 can move closer to or farther from the receiving groove 171, so that the nitrogen blowing tube 142 on the mounting frame 141 can move closer to or farther from the receiving groove 171, thereby completing nitrogen blowing. And the cost is low.

[0141] Figure 8 A cross-sectional view of the base of the nitrogen blowdown apparatus provided in the embodiment of the present application, such as Figures 1 to 8 As shown, in some optional embodiments, a sample box 170 is further included, and the base 110 has a placement cavity 111 for accommodating the sample box 170;

[0142] The sample box 170 has a cover plate 172 . Two opposite sides of the cover plate 172 are provided with grooves 1721 . The receiving groove 171 is located in the sample box 170 , and the notch of the receiving groove 171 is opened on the cover plate 172 .

[0143] It should be noted that the design of the sample box 170 allows the sample bottles 200 placed in the sample box 170 to be moved as a whole through the sample box 170 to avoid taking them out one by one, which can reduce unnecessary work for the next quality inspection process and nitrogen blowing work and save time.

[0144] In some embodiments, a soft cushion 1711 is provided at the bottom of the receiving groove 171 to prevent the sample bottle 200 from being accidentally bumped and broken when being placed therein.

[0145] In addition, it should be noted that the grooves 1721 on the opposite sides are intended to facilitate quality inspectors to take and place the cover plate 172 through the grooves 1721, which is equivalent to the function of a handle.

[0146] It should be noted that the working process of the entire nitrogen blowdown instrument 100 is as follows: when using the device, the prepared sample bottle 200 containing the solution can be placed on the base 110. At this time, the sample bottle 200 is first passed through the notch of the receiving groove 171 on the cover plate 172, so that the sample bottle 200 falls into the receiving groove 171, and then the controller 133 is operated to start the second driving member 132, so that the second driving member 132 rotates, so that the position of the jet assembly 140 is lowered, and the nitrogen blowdown tube 142 enters the sample bottle 200, and then the nitrogen storage box connected to it is operated for nitrogen blowing.

[0147] The nitrogen blowdown instrument provided in the embodiment of the present application includes a base, a bracket, a driving assembly and an injection assembly. The bracket is arranged on the base, and a plurality of receiving slots are provided on the base, and the receiving slots are used to receive sample bottles; the injection assembly includes a mounting frame and a plurality of nitrogen blowpipes arranged on the mounting frame, and the mounting frame is movably arranged on the bracket; the driving assembly includes a first driving member, the first driving member is arranged on the bracket, the first driving member has a driving end connected to the mounting frame, and is used to drive the mounting frame to approach or move away from the receiving slot, the nitrogen blowpipe has a spray head facing the receiving slot, and the spray head is configured to extend into the sample bottle under the drive of the first driving member to blow nitrogen to the sample in the sample bottle.

[0148] Through the design of the jet assembly and the drive assembly, the nitrogen blowing pipe on the jet assembly can be moved under the drive of the first drive member on the drive assembly, and then extended into the sample bottle to blow nitrogen to the sample, thereby completing the nitrogen blowing process; in addition, by providing a nozzle head on the nitrogen blowing pipe, when the nitrogen is sprayed, the nozzle head with a shower structure similar to that of a shower head can increase the contact area between the nitrogen and the sample liquid when the nitrogen is sprayed, thereby reducing the nitrogen blowing time and saving nitrogen, and preventing the liquid in the nitrogen blowing bottle from splashing out or spraying onto the nitrogen blowing pipe due to excessive airflow, thereby causing losses.
