Description

Fire extinguishing agent column cutting and coating system and method Technical Field

[0001] The present invention relates to the technical field of fire extinguishing, and in particular to a system and method for cutting and coating fire extinguishing agent columns. Background Art

[0002] With the development of new energy and energy storage, the interior of the energy storage battery box is becoming more and more crowded, and the space for installing fire extinguishing equipment is also getting smaller and smaller. Therefore, the volume of the fire extinguishing equipment supporting the energy storage is required to be flatter. Aerosol fire extinguishing agents are different from water-based fire extinguishing agents and dry powder fire extinguishing agents. Aerosol fire extinguishing agents are usually in the form of powder columns. The powder columns of aerosol generators are usually pressed by aerosol generator powder and are usually cylindrical. However, in some special scenarios, for example, the combustion cross-section of the fire extinguishing agent column needs to be periodically increased and decreased continuously, so that the eruption intensity of the fire extinguishing substance generated by its combustion will be periodically increased and decreased. The pressure inside the battery compartment increases and decreases periodically, and when the pressure inside the battery compartment increases, the flammable gas diluted by the fire extinguishing substance can be pressed out from the gap in the battery compartment, and when the pressure inside the battery compartment decreases, the flammable gas inside the battery escapes into the battery compartment, and finally the flammable gas generated in the battery is diluted by the fire extinguishing substance and continuously discharged from the battery compartment, completing the entire fire extinguishing process; this cylindrical charge structure with flat surfaces on both sides can make the fire extinguishing process more efficient and effectively prevent the risk of a large amount of flammable gas in the battery overflowing after the fire extinguishing device stops spraying.

[0003] However, this cylindrical charge structure with flat surfaces on both sides is difficult to manufacture directly using a correspondingly shaped pressing mold. This is because if the charge is pressed directly using a correspondingly shaped pressing mold, the mold is very likely to crack at the intersection of the curved surface and the flat surface. Therefore, it is necessary to pre-press the cylindrical fire extinguishing agent charge using a cylindrical mold, and then perform the cutting and coating process on the fire extinguishing agent charge.

[0028] 3. During the cutting process, the present invention goes through multiple turning processes and then pushes the mobile platform to move on the transverse slide rail, so that the end and side of the fire extinguishing agent column can be cut, making the entire cutting process simple and efficient.

[0029] 4. The notch of the limiting cylinder in the present invention can also serve as a cutting positioning line. It is only necessary to align the edge line of the notch on the side of the limiting cylinder with the knife belt. This can ensure the accuracy and consistency of each cut and ensure that the two sides of each fire extinguishing agent column are cut in the same and accurate size.

[0030] 5. On the one hand, the limiting cylinder can ensure the limiting effect of the limiting cylinder on the fire extinguishing agent column, and on the other hand, it will not block or interfere with the cutting process of the knife belt. Thirdly, when feeding and cutting the side of the fire extinguishing agent column, after cutting one side of the fire extinguishing agent column, it only needs to be retreated and rotated 180°, and then it can be fed and cut again to cut the other side of the fire extinguishing agent column. Therefore, this structural design simplifies the entire fire extinguishing agent column cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0044] As shown in Figures 1 to 12, a fire extinguishing agent column cutting and coating system includes a cutting mechanism 3 and a coating mechanism 1. The coating mechanism 1 includes a silica gel coating groove 1.1. The cutting mechanism 3 includes a vertical cutting machine 3.1. A slide groove 1.2 is provided in the silica gel coating groove 1.1. The slide groove 1.2 is slidably engaged with a positioning foot 1.3. The positioning foot 1.3 is used to support the fire extinguishing agent column 2; a rotatable and movable limiting cylinder 3.3 is provided on the cutting platform 3.2 of the vertical cutting machine 3.1, and a knife belt 3.4 for vertical cutting is provided above the limiting cylinder 3.3.

[0045] Preferably, the fire extinguishing agent charge 2 is cylindrical, and the limiting cylinder 3.3 is cylindrical, with its curved surface matching the curved surface on the outside of the fire extinguishing agent charge 2. Two notches 3.3.1 for vertical cutting are provided in portions on both sides of the limiting cylinder 3.3. A first connecting curved plate 3.3.2 is provided at one end of the limiting cylinder 3.3 near one of the notches 3.3.1, and a second connecting curved plate 3.3.3 is provided at the other end of the limiting cylinder 3.3 near the other notch 3.3.1. In this embodiment, the notches 3.3.1 can also serve as cutting positioning lines. Simply aligning the edge of the notch 3.3.1 on the side of the limiting cylinder 3.3 with the knife band 3.4 ensures the accuracy and consistency of each cut, ensuring that the two sides of each fire extinguishing agent charge 2 are of uniform and accurate size. In addition, as shown in the figure, the reason for designing the limiting cylinder 3.3 of this connection structure is that, on the one hand, it can ensure the limiting effect of the limiting cylinder 3.3 on the fire extinguishing agent column 2, and on the other hand, it will not block or interfere with the cutting process of the knife belt 3.4. Thirdly, when feeding and cutting the side of the fire extinguishing agent column 2, after cutting one side of the fire extinguishing agent column 2, it only needs to be retreated and rotated 180°, and then it can be fed and cut again, so as to cut the other side of the fire extinguishing agent column 2. This structural design simplifies the entire fire extinguishing agent column cutting process.

[0046] Preferably, the fire extinguishing agent column 2 is a columnar structure formed by pressing an aerosol generating agent powder. Two parallel slide grooves 1.2 are provided at the bottom of the silica gel coating groove 1.1. A plurality of positioning feet 1.3 supporting the fire extinguishing agent column 2 are provided in the slide groove 1.2. The top of the positioning foot 1.3 is in an arc shape that matches the outer side of the fire extinguishing agent column 2. The aerosol generating agent pressed into this columnar structure burns more slowly than the powdered aerosol generating agent, which can ensure the continuity of the release of the fire extinguishing material. By sliding the positioning foot 1.3 in the slide groove 1.2, multiple fire extinguishing agent columns 2 can be brought close to and in contact with each other to form a combination for the coating process. The top of the positioning foot 1.3 is in an arc shape that matches the outer side of the fire extinguishing agent column 2, which can ensure stability during support.

[0047] The aerosol generator is a prior art, for example, the invention patent with Chinese patent publication number CN101745195B discloses an "aging-resistant aerosol generator and its preparation process", which discloses that the aerosol generator is composed of an oxidant, a reducing agent, and a binder, wherein the oxidant is potassium nitrate, the binder is phenolic resin, and the reducing agent is melamine, and the mass percentages thereof are: potassium nitrate 74% to 80%, phenolic resin 8% to 15%, and the balance is melamine.

[0048] Its preparation method is:

[0049] Step 1: dissolving phenolic resin in ethanol to prepare a phenolic resin solution with a mass percentage concentration of 40% to 55%;

[0050] Step 2: Grind the oxidizing agent and reducing agent to a fineness of 80-200 standard mesh, mix them according to the required proportion, and sieve them through 80-200 mesh three times to make them evenly mixed;

[0051] Step 3: Then add the phenolic resin solution to the mixed powder, stir for 10 minutes, and then use a 40-mesh screen to force granulate. Then dry the agent in an environment with a temperature of 40°C and a relative humidity of less than 20% until the volatile components are less than 1%;

[0052] Step 4: Press the dried medicine under a pressure of 10 MPa to form an aerosol generating agent column.

[0053] Preferably, the bottom of the limiting cylinder 3.3 is fixed to the top of the rotating platform 3.8 via a support column 3.7. The bottom of the rotating platform 3.8 is rotatably connected to the top of the movable platform 3.9. The bottom of the movable platform 3.9 slidably engages with a transverse slide rail 3.11 provided on the surface of the cutting platform 3.2 via a slide seat 3.10. In this embodiment, the bottom of the rotating platform 3.8 and the top of the movable platform 3.9 can be rotatably connected via a pin.

[0054] Preferably, a side limiting mechanism 3.5 is provided on the surface of the moving platform 3.9 at the side of the limiting cylinder 3.3, and an end limiting mechanism 3.6 is provided on the surface of the moving platform 3.9 at the end of the limiting cylinder 3.3.

[0055] Preferably, the side limiting mechanism 3.5 includes a side support plate 3.5.1 fixedly mounted on the top of the mobile platform 3.9. An internal threaded hole is provided in the side support plate 3.5.1 and threadedly engaged with a side screw rod 3.5.2. One end of the side screw rod 3.5.2 is fixedly connected to the side rotary handle 3.5.3, and the other end is rotationally connected to a curved push plate 3.5.4 via a bearing. The curved push plate 3.5.4 engages with the side of the fire extinguishing agent column 2. Specifically, by rotating the side rotating handle 3.5.3, the side screw 3.5.2 can be rotated. Since the side screw 3.5.2 is threadedly engaged with the side support plate 3.5.1, the side screw 3.5.2 drives the arcuate push plate 3.5.4 toward the side of the limiting cylinder 3.3, and the arcuate push plate 3.5.4 contacts the fire extinguishing agent column 2 from the notch 3.3.1 on the side of the limiting cylinder 3.3. Since the side screw 3.5.2 is rotationally connected to the arcuate push plate 3.5.4 through the bearing, when the side screw 3.5.2 continues to rotate, the arcuate push plate 3.5.4 will not rotate, and can compress the fire extinguishing agent column 2 to limit it.

[0056] Preferably, the end limit mechanism 3.6 includes an end support plate 3.6.1 fixedly mounted on the top of the mobile platform 3.9. The end support plate 3.6.1 defines an internally threaded hole threadedly engaged with an end screw 3.6.2. One end of the end screw 3.6.2 is fixedly connected to the end rotary handle 3.6.3, and the other end is rotationally connected to a planar push plate 3.6.4 via a bearing. The planar push plate 3.6.4 engages with the end of the fire extinguishing agent column 2. Specifically, by rotating the end rotating handle 3.6.3, the end screw 3.6.2 can be rotated. Since the end screw 3.6.2 is threadedly engaged with the end support plate 3.6.1, the end screw 3.6.2 drives the flat push plate 3.6.4 toward the end of the limit cylinder 3.3, and the flat push plate 3.6.4 contacts the end of the fire extinguishing agent column 2 from the end of the limit cylinder 3.3. Since the end screw 3.6.2 is rotationally connected to the flat push plate 3.6.4 through a bearing, when the end screw 3.6.2 continues to rotate, the flat push plate 3.6.4 will not rotate, and the fire extinguishing agent column 2 can be pushed, thereby adjusting the length of one end of the fire extinguishing agent column 2 extending out of the limit cylinder 3.3.

[0057] Preferably, the bottom of the transverse slide rail 3.11 is also vertically slidably connected to two longitudinal guide rails 3.12, and the bottom of the longitudinal guide rails 3.12 is fixed to the surface of the cutting platform 3.2. The limiting cylinder 3.3 itself can slide laterally along the transverse slide rails 3.11 via the movable platform 3.9, and the longitudinal guide rails 3.12 are designed so that the transverse slide rails 3.11 can slide longitudinally along the longitudinal guide rails 3.12. This allows the entire limiting cylinder 3.3 to slide both laterally and longitudinally across the entire cutting platform 3.2, improving the convenience of the cutting operation.

[0058] In addition, the present invention also discloses a coating and cutting method of the fire extinguishing agent column coating and cutting system, which comprises the following steps:

[0059] S1: A cylindrical fire extinguishing agent column 2 is obtained by pressing through a cylindrical pressing mold;

[0060] S2: Place the entire fire extinguishing agent column 2 on the limiting cylinder 3.3, and adjust and limit the fire extinguishing agent column 2 in the limiting cylinder 3.3 through the end limiting mechanism 3.6 and the side limiting mechanism 3.5;

[0061] S3: The vertical cutting machine 3.1 is turned on, and its knife belt 3.4 is rotated. The position of the transverse slide 3.11 on the longitudinal guide rail 3.12 is adjusted so that the position to be cut of one end of the fire extinguishing agent charge 2 is aligned with the knife belt 3.4 (as shown in FIG4 ). Then, the movable platform 3.9 is pushed to move on the transverse slide 3.11. When the fire extinguishing agent charge 2 passes through the knife belt 3.4, one end of the fire extinguishing agent charge 2 is cut, and the limiting effects of the end limiting mechanism 3.6 and the side limiting mechanism 3.5 are released.

[0062] S4: Rotate the rotating platform 3.8 180 degrees, adjust and limit the fire extinguishing agent charge 2 in the limiting cylinder 3.3 through the end limiting mechanism 3.6 and the side limiting mechanism 3.5, adjust the position of the transverse slide rail 3.11 on the longitudinal guide rail 3.12 so that the other end of the fire extinguishing agent charge 2 to be cut is aligned with the knife belt 3.4 (as shown in Figure 5), and then push the movable platform 3.9 in the opposite direction on the transverse slide rail 3.11. When the fire extinguishing agent charge 2 passes through the knife belt 3.4, the other end of the fire extinguishing agent charge 2 is cut, and the limiting effect of the end limiting mechanism 3.6 and the side limiting mechanism 3.5 is released;

[0063] S5: Rotate the rotating platform 3.8 90 degrees, adjust and limit the fire extinguishing agent charge 2 in the limiting cylinder 3.3 through the end limiting mechanism 3.6 and the side limiting mechanism 3.5, adjust the position of the transverse slide 3.11 on the longitudinal guide rail 3.12 so that the position to be cut on one side of the fire extinguishing agent charge 2 is aligned with the knife belt 3.4 (as shown in Figure 6), and then push the movable platform 3.9 to move on the transverse slide 3.11 so that when the fire extinguishing agent charge 2 passes through the knife belt 3.4, one side of the fire extinguishing agent charge 2 is cut; push the movable platform 3.9 in the opposite direction to return the movable platform 3.9 from the transverse slide 3.11 to its original path, and release the limiting effect of the end limiting mechanism 3.6 and the side limiting mechanism 3.5;

[0064] S6: Rotate the rotating platform 3.8 180 degrees, and adjust and limit the fire extinguishing agent charge 2 in the limiting cylinder 3.3 through the end limiting mechanism 3.6 and the side limiting mechanism 3.5, so that the position to be cut on the other side of the fire extinguishing agent charge 2 is aligned with the knife belt 3.4 (as shown in Figure 7). Push the movable platform 3.9 to move on the transverse slide 3.11. When the fire extinguishing agent charge 2 passes through the knife belt 3.4, the other side of the fire extinguishing agent charge 2 is cut. The movable platform 3.9 is retracted from the transverse slide 3.11 along the original path, and the limiting effects of the end limiting mechanism 3.6 and the side limiting mechanism 3.5 are released. The entire cutting process is completed (as shown in Figures 8 and 9).

[0065] S7: Place multiple fire extinguishing agent charges 2 on top of multiple sets of positioning feet 1.3 in the silica gel coating groove 1.1. Slide the positioning feet 1.3 in the slide groove 1.2 to ensure close contact between the multiple fire extinguishing agent charges 2 (as shown in Figure 11). Then, set baffles on the sides of the outermost fire extinguishing agent charges 2 to prevent the multiple fire extinguishing agent charges 2 from loosening.

[0066] S8: Pour high-temperature liquid silica gel into the silica gel coating groove 1.1. After the silica gel solidifies, take out the coated fire extinguishing agent column 2 to complete the entire coating process (as shown in Figure 12); in this embodiment, silica gel is provided on the fire extinguishing agent column because during the fire extinguishing process, silica gel can effectively isolate the heat generated by the combustion of the fire extinguishing agent column 2, thereby preventing the surface temperature of the fire extinguishing device shell from being too high.

[0067] Preferably, the specific process of the end limiting mechanism 3.6 and the side limiting mechanism 3.5 adjusting and limiting the fire extinguishing agent column 2 in the limiting cylinder 3.3 is as follows:

[0068] The position of the flat push plate 3.6.4 is adjusted by the end limit mechanism 3.6, thereby adjusting the length of one end of the fire extinguishing agent charge 2 extending beyond the limit cylinder 3.3. Then, the position of the curved push plate 3.5.4 is adjusted by the side limit mechanism 3.5, so that the curved push plate 3.5.4 contacts the fire extinguishing agent charge 2 through the notch 3.3.1 on the side of the limit cylinder 3.3, thereby limiting its position.

[0069] In this embodiment, the fire extinguishing agent column shown in Figure 9 is a cylindrical structure with both sides cut into a plane structure. After the cut plane is first ignited, its combustion cross-section first increases and then decreases; after multiple cylindrical structures are combined together, the combustion cross-section will periodically increase and decrease (as shown in Figure 12).
