{First embodiment}
(Outline)
1st Embodiment is related with the apparatus which injects an expanded vermiculite.

  The schematic diagram of FIG. 1 is a piping diagram of a device for injecting expanded vermiculite. 2 and 3 are perspective views of the injection nozzle. 4 and 5 are cross-sectional views of the transport hose and the injection nozzle.

  As shown in FIG. 1, an apparatus 1000 for injecting expanded meteorite includes a pressure vessel 1010, expanded meteorite 1011, a supply mechanism 1012, a discharge pipe 1013, a valve 1014, a transport hose 1015, and an injection nozzle 1016.

  The supply mechanism 1012 includes a cylinder 1020, a pressurized gas 1021, a supply pipe 1022, a primary pressure reducing valve 1023, and a secondary pressure reducing valve 1024.

  Components other than these components may be added to the apparatus 1000 for injecting expanded meteorite. Some of these components may be omitted from the apparatus 1000 for injecting expanded stone.

  As shown in FIG. 1, a pressure chamber 1030 is formed in the pressure vessel 1010. A discharge passage 1040 is formed in the discharge pipe 1013. The valve 1014 is formed with an in-valve channel 1050. A transport channel 1060 is formed in the transport hose 1015. As shown in FIGS. 4 and 5, the injection nozzle 1016 is formed with an in-nozzle flow path 1070 and an injection hole 1071.

  As shown in FIG. 1, the discharge channel 1040 extends from the pressure chamber 1030 to the outside of the pressure vessel 1010. The transport channel 1060 communicates with the discharge channel 1040 via the in-valve channel 1050. The transport channel 1060 is downstream from the discharge channel 1040. The valve 1014 may be omitted. When the valve 1014 is omitted, the transport channel 1060 leads to the discharge channel 1040 without passing through the in-valve channel 1050. As shown in FIGS. 4 and 5, the in-nozzle channel 1070 communicates with the transport channel 1060. The in-nozzle channel 1070 is downstream of the transport channel 1060. The injection hole 1071 communicates with the in-nozzle channel 1070 and communicates with the transport channel 1060 through the in-nozzle channel 1070. The injection hole 1071 is downstream of the in-nozzle channel 1070 and the transport channel 1060.

  When the expanded vermiculite 1011 is injected, the supply mechanism 1012 supplies the pressurized gas 1021 to the pressure chamber 1030. The valve 1014 is opened, and the expanded meteorite 1011 accommodated in the pressure chamber 1030 is pumped from upstream to downstream by the pumping gas 1021. The expanded vermiculite 1011 is discharged from the pressure chamber 1030 to the outside of the pressure vessel 1010 via the discharge flow path 1040, passes through the valve flow path 1050, and is transported via the transport flow path 1060. It is injected from the injection hole 1071 via the path 1070. The injection hole 1071 is directed to the fire source. The injection nozzle 1016 may be hand-held by an operator or may be fixed to equipment. The expanded vermiculite 1011 goes to the fire source, covers the fire source, and mainly contributes to suffocation extinction.

(Characteristics of expanded vermiculite)
The expanded vermiculite 1011 is useful as a fire extinguishing agent for suffocation, and is recognized as a type 5 fire fighting facility in the Fire Service Act of Japan. The expanded vermiculite 1011 has properties different from those of granular materials such as sand and ceramic powder. For example, the expanded vermiculite 1011 has a small specific gravity, a large porosity, and a compressibility. For this reason, when the extinguishing agent is the expanded vermiculite 1011, the equipment to be extinguished is not easily damaged, and the power required for discharging, transporting and injecting the extinguishing agent is reduced. On the other hand, when the fire extinguishing agent is the expanding stone 1011, the fire extinguishing agent tends to clog the flow path.

  The apparatus 1000 for injecting an expanded vermiculite can discharge the expanded vermiculite 1011 without delay, transport it without delay, inject it without delay, and operates reliably in an emergency. The apparatus 1000 for injecting expanded vermiculite is preferably used to extinguish a fire of a sodium-sulfur battery. However, the apparatus 1000 for injecting expanded vermiculite may be used for extinguishing fires other than sodium-sulfur batteries.

(Desirable ratio of expanded vermiculite)
The expanded vermiculite 1011 is mixed with the pressurized gas 1021 supplied from the supply mechanism 1012, discharged through the discharge channel 1040, transported through the transport channel 1060, and injected from the injection nozzle 1016. Is done. There is a desirable range in the ratio of the expanded vermiculite 1011 in the mixed flow of the expanded vermiculite 1011 and the pressurized gas 1021. When the ratio of the expanded vermiculite 1011 is large, the pressure gas required for discharging, transporting, and injecting the expanded vermiculite 1011 decreases, but the expanded vermiculite 1011 tends to be clogged in the flow path. When the ratio of the expanded vermiculite 1011 is small, the expanded vermiculite 1011 is less likely to be clogged in the flow path, but the pumping gas necessary for discharging, transporting, and injecting the expanded vermiculite 1011 increases.

(Flow path through which expanded vermiculite is pumped)
As shown in FIG. 1, the transport hose 1015 and the discharge pipe 1013 are connected via a valve 1014. When the valve 1014 is opened, the transport channel 1060 communicates with the discharge channel 1040 via the in-valve channel 1050. When the valve 1014 is omitted, the transport hose 1015 and the discharge pipe 1013 are directly connected, and the transport flow path 1060 leads to the discharge flow path 1040.

  As shown in FIGS. 4 and 5, the injection nozzle 1016 and the transport hose 1015 are connected. The in-nozzle channel 1070 communicates with the transport channel 1060.

  The injection hole 1071 communicates with the in-nozzle flow path 1070.

  Generally speaking, one flow path forming body and the other flow path forming body may be connected via an inclusion such as a coupling or a valve, or may be directly connected. Therefore, one channel may communicate with the other channel via the interposed channel formed in the inclusion, or may directly communicate with the other channel. When one flow path leads to the other flow path, a mixed flow of expanded stone 1011 and pressurized gas 1021 can flow from the other flow path to the one flow path. The flow path forming body includes a discharge pipe 1013 which is a discharge flow path forming body in which the discharge flow path 1040 is formed, a transport hose 1015 which is a transport flow path forming body in which the transport flow path 1060 is formed.

(Relationship between cross section of transport flow path, cross section of flow path in nozzle and opening of injection hole)
As shown in FIGS. 2 to 5, the cross section of the in-nozzle flow path 1070 is wider than the cross section of the transport flow path 1060. The opening of the injection hole 1071 is narrower than the cross section of the transport channel 1060. The cross-sectional area of the in-nozzle flow path 1070 is larger than the cross-sectional area of the transport flow path 1060. The opening area of the injection hole 1071 is smaller than the cross-sectional area of the transport channel 1060.

  When the opening of the injection hole 1071 is made narrower than the cross section of the transport channel 1060, the expanded meteorite 1011 is jetted vigorously. However, when the opening of the injection hole 1071 is simply narrower than the cross section of the transport channel 1060, the expanded meteorite 1011 is likely to be clogged in the channel. In particular, when the ratio of the expanded vermiculite 1011 in the mixed flow of the expanded vermiculite 1011 and the pressurized gas 1021 is large, the expanded vermiculite 1011 tends to clog the flow path.

  When the cross section of the nozzle inner flow path 1070 is wider than the cross section of the transport flow path 1060, even if the opening of the injection hole 1071 is narrower than the cross section of the transport flow path 1060, the expanded vermiculite 1011 is less likely to clog the flow path. .

  However, even when the above relationship is not satisfied, the usefulness of the apparatus 1000 for injecting expanded meteorite is not completely lost. For example, when the ratio occupied by the expanded vermiculite 1011 in the mixed flow is small, the expanded vermiculite 1011 is not easily clogged in the flow path even when the above relationship is not satisfied. However, when the ratio occupied by the expanded vermiculite 1011 is small, the time required to embed the fire source with the expanded vermiculite 1011 becomes longer, and a large amount of pumping gas 1021 is required.

  The cross-sectional shape of the in-nozzle flow path 1070 and the opening shape of the injection hole 1071 are rectangular. In the rear end portion 1075 and the front end portion 1077 of the nozzle inner flow path 1070, the width and height of the cross section of the nozzle inner flow path 1070 are constant, and the cross sectional area of the nozzle inner flow path 1070 is constant. In the intermediate portion 1076 of the nozzle inner flow passage 1070, the width of the cross section of the nozzle inner flow passage 1070 is constant, but the height of the cross section of the nozzle inner flow passage 1070 is from the rear end portion 1075 side to the front end portion 1077 side. The cross-sectional area of the in-nozzle flow path 1070 decreases continuously as it progresses, and decreases continuously as it proceeds from the rear end portion 1075 side to the front end portion 1077 side. The cross-sectional shape of the in-nozzle flow path 1070 may be other than a rectangle. The opening shape of the injection hole 1071 may be other than a rectangle.

(Connection of transport hose and injection nozzle)
As shown in FIGS. 2 to 5, the injection nozzle 1016 includes a main body 1080 and a transport hose connection portion 1081. The transport hose connection portion 1081 includes a cylinder 1090 and a set screw 1091.

  In the main body 1080, an in-nozzle flow path 1070 and an injection hole 1071 are formed. A transport hose insertion hole 1100 is formed in the cylinder 1090. The in-nozzle channel 1070 leads to the transport hose insertion hole 1100. The injection hole 1071 communicates with the transport hose insertion hole 1100 via the in-nozzle flow path 1070.

  A transport hose 1015 is inserted into the transport hose insertion hole 1100. The transport hose 1015 is fixed by a set screw 1091. The tip of the set screw 1091 preferably has a pointed tip shape. The set screws 1091 are desirably arranged at equal intervals in the circumferential direction of the cylinder 1090. When the transport hose 1015 is fixed by the four set screws 1091, the four set screws 1091 are arranged at 90 ° intervals in the circumferential direction of the cylinder 1090. The number of set screws 1091 may be 3 or less, or 5 or more.

  When the transport hose 1015 is inserted into the transport hose insertion hole 1100 formed in the cylinder 1090, the cross section of the flow path is widened at the connection point between the transport hose 1015 and the injection nozzle 1016. As a result, the expanded vermiculite 1011 is less likely to clog the flow path.

  The transport hose 1015 may be fixed by a fixing mechanism other than the set screw 1091. For example, the transport hose 1015 may be fixed by a claw, a band, a tape, an adhesive, or the like. The gap between the outer peripheral surface of the transport hose 1015 and the inner peripheral surface of the cylinder 1090 may be filled with a filler. For example, the gap may be filled with a silicon sealant. The structure of the transport hose connection part 1081 may be changed. For example, the transport hose 1015 and the injection nozzle 1016 may be connected by a flange pair.

  The cross-sectional shape of the transport hose insertion hole 1100 is circular. The cross-sectional shape of the transport hose insertion hole 1100 should match the cross-sectional shape of the transport hose 1015 to be inserted. For this reason, the cross-sectional shape of the transport hose insertion hole 1100 may be other than circular.

(Direction toward the upstream end of the discharge channel)
As shown in FIG. 1, the upstream end of the discharge pipe 1013 is in the pressure chamber 1030. The downstream end of the discharge pipe 1013 is outside the pressure vessel 1010. An upstream end portion 1090 of the discharge channel 1040 is exposed at an upstream end portion of the discharge pipe 1013, is in the pressure chamber 1030, and is brought close to the bottom of the pressure chamber 1030. The upstream end portion 1090 of the discharge channel 1040 is buried in the expanded vermiculite 1011.

  The upstream end 1090 of the discharge channel 1040 faces downward in the vertical direction. In this case, the expanded vermiculite 1011 is unlikely to enter the discharge flow path 1040 by its own weight, and the expanded vermiculite 1011 remains in the pressure chamber 1030 until the pumping starts. As a result, the expanded vermiculite 1011 is less likely to clog the discharge flow path 1040.

  Even when the extending direction of the discharge flow path 1040 is changed and the direction in which the upstream end portion 1090 of the discharge flow path 1040 faces is changed, the usefulness of the apparatus 1000 for injecting expanded meteorite is completely lost. Absent.

(curvature radius)
As shown in FIG. 1, the discharge pipe 1013 includes a curved portion 1110 and a non-curved portion 1111. A curved discharge section 1120 and a non-curved discharge section 1121 of the discharge flow path 1040 are formed in a curved portion 1110 and a non-curved portion 1111, respectively. The non-curved portion 1111 may be omitted. The discharge pipe 1013 may include two or more curved portions 1110, and the discharge flow path 1040 may include two or more curved discharge sections 1120. The discharge pipe 1013 may include two or more non-curved portions 1111, and the discharge flow path 1040 may include two or more non-curved discharge sections 1121.

  The radius of curvature of the center line 1130 of the curved discharge section 1120 is preferably 5 to 10 times the inner diameter of the curved discharge section 1120. When the radius of curvature is within this range, the expanded vermiculite 1011 is less likely to clog the flow path, and the discharge pipe 1013 does not become too large. When the radius of curvature is smaller than this range, the expanded vermiculite 1011 tends to clog the flow path. When the radius of curvature is larger than this range, the discharge pipe 1013 becomes too large. When the discharge flow path 1040 includes two or more curved discharge sections 1120, preferably all the curved discharge sections 1120 satisfy the above conditions.

(Two steps of decompression)
As shown in FIG. 1, a filling chamber 1140 is formed in the cylinder 1020. The filling chamber 1140 is filled with a pressurized gas 1021. A supply flow path 1150 is formed in the supply pipe 1022. Supply channel 1150 extends from filling chamber 1140 to pressure chamber 1030.

  The primary pressure reducing valve 1023 and the secondary pressure reducing valve 1024 are in the middle of the supply pipe 1022. The secondary pressure reducing valve 1024 is downstream from the primary pressure reducing valve 1023.

  The pressurized gas 1021 exits the filling chamber 1140 and enters the pressure chamber 1030 through the supply flow path 1150. The pressurized gas 1021 sequentially passes through the primary pressure reducing valve 1023 and the secondary pressure reducing valve 1024. The primary pressure reducing valve 1023 reduces the pressure of the pressurized gas 1021. The secondary pressure reducing valve 1024 further reduces the pressure of the pressurized gas 1021. The reason why two-stage pressure reduction is performed by the primary pressure reducing valve 1023 and the secondary pressure reducing valve 1024 is that the pressure of the pressurized gas 1021 filled in the filling chamber 1140 can be reduced to the pressure when it is supplied to the pressure chamber 1030. This is because the pressure reducing valve that can secure the flow rate of the gas 1021 is rare. However, even when one-stage decompression is performed, the usefulness of the apparatus 1000 for injecting expanded meteorite is not completely lost. Three or more pressure reductions may be performed.

(Pressure gas pressure)
The pressure of the pressurized gas 1021 filled in the filling chamber 1140 is 14 MPa. However, the pressure of the pressurized gas 1021 filled in the filling chamber 1140 may be other than 14 MPa.

  The primary pressure reducing valve 1023 desirably reduces the pressure of the pumping gas 1021 from 3 MPa or more to 0.8 MPa. However, the primary pressure of the primary pressure reducing valve 1023 may be less than 3 MPa. The secondary pressure of the primary pressure reducing valve 1023 may be other than 0.8 MPa.

  The secondary pressure reducing valve 1024 desirably reduces the pressure of the pumping gas 1021 from 0.8 MPa or more to 0.2 MPa. However, the primary pressure of the secondary pressure reducing valve 1024 may be less than 0.8 MPa. The secondary pressure of the secondary pressure reducing valve 1024 may be other than 0.2 MPa.

  The pressurized gas 1021 filled in the filling chamber 1140 is desirably adjusted to 0.2 MPa or less by the primary pressure reducing valve 1023 and the secondary pressure reducing valve 1024 and then introduced into the pressure chamber 1030. Thereby, the particles of the expanded vermiculite 1011 are less likely to be damaged, and the bulk of the expanded vermiculite 1011 is maintained. The pressure of the pressurized gas 1021 is more desirably 0.05 MPa or more.

(Type of pressure gas)
The pressurized gas 1021 is desirably nitrogen gas. Nitrogen gas can be high pressure as a gas, and it is easy to increase the flow rate. However, the pressurized gas 1021 may be other than nitrogen gas. For example, the pressurized gas 1021 may be carbon dioxide.

(Flexibility)
The discharge pipe 1013 is inflexible. Thereby, the discharge flow path 1040 is stabilized, and the expanded vermiculite 1011 is discharged stably. The discharge pipe 1013 is made of, for example, a metal or an alloy. The metal is, for example, iron. The alloy is, for example, stainless steel. All or part of the discharge pipe 1013 may be replaced with a flexible discharge hose.

  The transport hose 1015 is flexible. Thereby, the position and posture of the injection nozzle 1016 are easily adjusted. The transport hose 1015 is made of rubber, for example. All or part of the transport hose 1015 may be replaced with an inflexible transport pipe.

  The supply tube 1022 is inflexible. All or part of the supply tube 1022 may be replaced with a flexible supply hose.

  The injection nozzle 1016 is inflexible. Thereby, the flow path 1070 in the nozzle, the injection hole 1071, and the transport hose insertion hole 1100 are stabilized, and the expanded meteorite 1011 is stably injected. The injection nozzle 1016 is made of the same material as the discharge pipe 1013.

{Second Embodiment}
(Outline)
The second embodiment relates to a transport composite that replaces the transport hose of the first embodiment.

  The schematic diagram of FIG. 6 shows the transport composite. The schematic diagram of FIG. 7 is a cross-sectional view of the connection structure of the transport hose, the detachable body, and the curved transport pipe. The schematic diagram of FIG. 8 is a cross-sectional view of a connection structure of a curved transport pipe and a non-curved transport pipe.

  As shown in FIG. 6, the transport composite 2000 includes a transport hose 2010, a detachable body 2011, a coupling 2012, a curved transport pipe 2013, a coupling 2014 and a non-curved transport pipe 2015. Components other than these components may be added to the transport composite 2000. Some of these components may be omitted from the transport composite 2000.

  Just as the transport hose 1015 of the first embodiment is an example of a transport channel forming body, the transport complex 2000 of the second embodiment is also an example of a transport channel forming body. The transport composite 2000 according to the second embodiment is different from the transport hose 1015 according to the first embodiment in that the transport composite 2000 includes four divided bodies including a transport hose 2010, a detachable body 2011, a curved transport pipe 2013, and a non-curved transport pipe 2015. . The transport composite 2000 may be composed of five or more or three or less divided bodies.

  A transport channel 2020 is formed in the transport complex 2000. The transport sections 2030, 2031, 2032, and 2033 of the transport channel 2020 are formed in the transport hose 2010, the detachable body 2011, the curved transport pipe 2013, and the non-curved transport pipe 2015, respectively.

  The detachable body 2011 and the transport hose 2010 are connected. The transport section 2031 leads to the transport section 2030. The transport section 2031 is downstream from the transport section 2030.

  The curved transport tube 2013 and the detachable body 2011 are connected. The transport section 2032 leads to the transport section 2031. The transport section 2032 is downstream from the transport section 2031.

  The detachable body 2011 may be omitted. When the detachable body 2011 is omitted, the transport hose 2010 and the curved transport pipe 2013 are connected, and the transport section 2032 leads to the transport section 2030.

  The non-curved transport tube 2015 and the curved transport tube 2013 are connected. The transport section 2033 leads to the transport section 2032. The transport section 2033 is downstream from the transport section 2032.

(Connection structure of transport hose, detachable body and curved transport pipe)
As shown in FIG. 7, the detachable body 2011 includes single flange tubes 2040 and 2041 and a connecting bolt 2042. The single flange tube 2040 includes a tube 2043 and a flange 2044. The single flange tube 2041 includes a tube 2045 and a flange 2046. The flanges 2044 and 2046 are connected by a connecting bolt 2042. The transport hose 2010 is inserted into a transport hose insertion hole 2047 formed in the pipe 2043. The tube 2045 and the curved transport tube 2013 are connected by the coupling 2012 in a state where the end 2060 of the tube 2045 and the upstream end 2065 of the curved transport tube 2013 are in contact with each other. The tube 2045 and the curved transport tube 2013 may be coupled by a coupling mechanism other than the coupling 2012. The tube 2045 and the curved transport tube 2013 are inserted into holes 2110 formed in the coupling 2012.

  The cross-sectional shapes of the transport sections 2031 and 2032 are the same. The cross section of the flow path does not expand or narrow at the connection point between the detachable body 2011 and the curved transport tube 2013. For this reason, the expanded vermiculite 1011 is less likely to clog the flow path.

(Connection structure of curved transport pipe and non-curved transport pipe)
As shown in FIG. 8, the curved transport tube 2013 and the non-curved transport tube 2015 are coupled in a state where the downstream end portion 2070 of the curved transport tube 2013 and the upstream end portion 2080 of the non-curved transport tube 2015 are in contact with each other. It is connected by 2014. The curved transport tube 2013 and the non-curved transport tube 2015 may be coupled by a coupling mechanism other than the coupling 2014. The cross-sectional shapes of the transport sections 2032 and 2033 are the same. The cross section of the flow path does not expand or narrow at the connection point between the curved transport pipe 2013 and the non-curved transport pipe 2015. For this reason, the expanded vermiculite 1011 is less likely to clog the flow path. The cross section of the transport section 2033 may be wider than the cross section of the transport section 2032, and the cross section of the flow path may be widened at the connection point between the curved transport pipe 2013 and the non-curved transport pipe 2015.

(curvature radius)
As shown in FIG. 6, the radius of curvature of the center line 2100 of the curved transport section 2032 is desirably 5 to 10 times the inner diameter of the curved transport section 2032. When the radius of curvature is within this range, the expanded vermiculite 1011 is less likely to clog the flow path, and the curved transport pipe 2013 does not become too large. When the radius of curvature is smaller than this range, the expanded vermiculite 1011 tends to clog the flow path. When the radius of curvature is larger than this range, the curved transport tube 2013 becomes too large. In the case where the transport channel 2020 includes two or more curved transport sections 2032, desirably all the curved transport sections 2032 satisfy the above conditions.

(Fixing the transport pipe)
As shown in FIG. 6, the coupling 2012, the curved transport pipe 2013, the coupling 2014 and the non-curved transport pipe 2015 are preferably fixed to a facility 9001 that is extinguished together with the injection nozzle 9000. When the expanded vermiculite 1011 is not sprayed, the tube 2045 is removed from the hole 2110 formed in the coupling 2012, and the detachable body 2011 and the curved transport tube 2013 are disconnected. When the expanded vermiculite 1011 is injected, the tube 2045 is inserted into the hole 2110 formed in the coupling 2012, and the detachable body 2011 and the curved transport tube 2013 are connected. The equipment 9001 to be extinguished is, for example, a power storage device. A battery module is housed inside the casing of the power storage device. A cell of a sodium-sulfur battery is accommodated inside the battery module box.

  The non-curved transport tube 2015 desirably extends in the vertical direction. In this case, instead of the injection nozzle 1016 of the first embodiment, an injection nozzle 9000 in which the main body and the flow path in the nozzle are curved and the injection hole faces the horizontal direction is used. A transport pipe connecting portion to which the non-curved transport pipe 2015 is connected is provided in the injection nozzle 9000, and a transport pipe insertion hole into which the non-curved transport pipe 2015 is inserted is formed in the transport pipe connecting portion. The spray nozzle 1016 may be used as it is or after being deformed. When the spray nozzle 1016 is used as it is or after being deformed, the transport hose connection part 1081 functions as a transport pipe connection part to which the non-curved transport pipe 2015 is connected.

  While the invention has been shown and described in detail, the above description is illustrative in all aspects and not restrictive. Accordingly, it is understood that numerous modifications and variations can be devised without departing from the scope of the present invention.
