In the field of firefighting, fireproof fabric can be used to make firefighters' protective clothing, fire blankets and other equipment to protect personnel from fire damage; in the construction industry, fireproof fabric can be used as a fireproof partition material for building structures to improve the fire safety of buildings. Applying heat treatment technology to the production process of fireproof fabric can effectively improve the performance of fireproof fabric. Through heat treatment, the fiber molecular structure in the fireproof fabric can be rearranged and crystallized, and the strength and modulus of the fiber can be improved; it can promote the combination of fire retardant and fiber, and improve the fireproof performance of the fireproof fabric; it can also eliminate the stress inside the fireproof fabric and improve its dimensional stability and durability.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The heat treatment device for processing fireproof cloth according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 2-Figure 5 As shown, the heat treatment device for processing fireproof cloth provided by the embodiment of the present invention includes a shell component 1, a preheating mechanism 2, a heating mechanism 5 and a cooling mechanism 6, wherein the preheating mechanism 2, the heating mechanism 5 and the cooling mechanism 6 are connected end to end in sequence, and the preheating mechanism 2, the heating mechanism 5 and the cooling mechanism 6 are all arranged in the shell component 1, and a base 14 is arranged at the bottom of the shell component 1 for supporting the entire device.

[0023] The shell assembly 1 includes a shell top 11, a shell body 12 and a shell bottom 13, wherein the shell top 11, the shell body 12 and the shell bottom 13 are integrally connected, the shell top 11, the shell body 12 and the shell bottom 13 are all made of thermal insulation material, and the shell bottom 13 is used to guide the fireproof cloth after heat treatment.

[0024] The preheating mechanism 2 is used to preheat the fireproof cloth, and the preheating mechanism 2 includes a preheating roller 22, which is arranged on the inner side of the shell top 11. The heating mechanism 5 is used to continuously heat the fireproof cloth, and the heating mechanism 5 includes a heating plate 51, which is arranged on the inner side of the shell body 12. The cooling mechanism 6 is used to slowly cool the fireproof cloth, and the cooling mechanism 6 includes an energy storage brick 62, which is arranged on the inner side of the shell body 12.

[0025] Specifically, when the fireproof cloth is heat-treated, the fireproof cloth to be heat-treated is first fed from the shell top 11 into the preheating roller 22. The fireproof cloth first enters the preheating roller 22. After being preheated by the preheating roller 22, the temperature of the surface of the fireproof cloth continues to rise slowly and eventually approaches the baking temperature of the heat treatment. Then, the preheated fireproof cloth enters the heating plate 51. The heating plate 51 continuously heats the surface of the fireproof cloth to rearrange and crystallize the fiber molecular structure in the fireproof cloth, thereby promoting the combination of the fire retardant and the fiber.

[0026] During the heating process, the heat in the heating plate 51 is continuously transferred downward to the energy storage brick 62. The temperature of the energy storage brick 62 close to the heating plate 51 is the highest, and the temperature of the energy storage brick 62 away from the heating plate 51 gradually decreases. Then the fireproof cloth enters the inner side of the energy storage brick 62. As the fireproof cloth continues to move downward in the energy storage brick 62, the temperature of the fireproof cloth gradually decreases, thereby preventing the fiber structure from expanding or contracting rapidly and the fire retardant from solidifying rapidly, so that the fiber structure and the fire retardant are slowly cooled and fully combined. Finally, the fireproof cloth after the heat treatment is completed is recovered from the discharge port 131 of the shell bottom 13.

[0027] In one embodiment of the present invention, Figure 4 As shown, a preheating roller driving motor 25 is arranged on the outside of the shell top 11, and an infrared heating tube 21 is arranged on the inside of the shell top 11. The infrared heating tube 21 is an arc-shaped structure and is arranged on the outside of the preheating roller 22. The heating power of the infrared heating tube 21 increases successively along the rotation direction of the preheating roller 22.

[0028] Specifically, in the process of preheating the fireproof cloth, the fireproof cloth first contacts the heating surface 221 on the surface of the preheating roller 22 and is wrapped around the surface of the preheating roller 22. After the heating surface 221 is energized, it provides an initial temperature to the fireproof cloth, causing the internal temperature of the surface of the fireproof cloth to rise rapidly. Subsequently, as the preheating roller 22 continues to rotate, the fireproof cloth passes through the infrared heating tube 21. Since the heating power of the infrared heating tube 21 increases successively along the direction of rotation of the preheating roller 22, the fireproof cloth is heated linearly, making the heating process of the fireproof cloth more uniform, and finally making the fireproof cloth gradually reach the temperature required for heat treatment.

[0029] In one embodiment of the present invention, Figure 4 As shown, a preheating introduction roller 26 is arranged on the inner side of the shell top 11, and the preheating introduction roller 26 and the outer wall of the preheating roller 22 are close to each other. Arc-shaped adjustment bases 261 are arranged at both ends of the preheating introduction roller 26 along the rotation direction of the preheating roller 22, and a heating surface 221 is arranged on the outer surface of the preheating roller 22.

[0030] Specifically, the position of the preheating introduction roller 26 relative to the preheating roller 22 can be adjusted by adjusting the base 261. Figure 4 As shown, the contact area between the fireproof cloth and the preheating roller 22 is further adjusted. Therefore, it can be adjusted according to the fireproof cloth of different thicknesses. When the thickness of the fireproof cloth is relatively thick, the preheating introduction roller 26 is moved to the right to increase the contact area between the fireproof cloth and the preheating roller 22, so that the fireproof cloth heats up faster. When the thickness of the fireproof cloth is relatively thin, the preheating introduction roller 26 is moved to the left to reduce the contact area between the fireproof cloth and the preheating roller 22, so as to prevent the fireproof cloth from being damaged by heat due to long-term contact.

[0031] In one embodiment of the present invention, Figure 4As shown, a first vibrator 23 is disposed at the discharge end of the preheating roller 22 , a first vibrating roller 231 is disposed on the output shaft of the first vibrator 23 , and the first vibrating roller 231 and the outer wall of the preheating roller 22 are tightly connected to each other.

[0032] Specifically, the first vibrator 23 drives the first vibrating roller 231 to rotate and vibrate, and initially vibrates the preheated fireproof cloth, so that the fibers inside the fireproof cloth continuously adjust their positions, promoting the transfer and uniform distribution of heat. The vibration frequency and amplitude can be adjusted according to the material and thickness of the fireproof cloth to achieve the best heat treatment effect.

[0033] In one embodiment of the present invention, Figure 4 As shown, a tensioning roller 24 is provided at the feeding end of the heating plate 51 , and the inlet and outlet ends of the tensioning roller 24 are fixedly guided by guide rollers 242 , and tensioning springs 241 are provided at both ends of the tensioning roller 24 .

[0034] There are two heating plates 51 , and spoilers 52 are provided on opposite sides of the two heating plates 51 . Raised spoiler patterns are provided on the surface of the spoilers 52 . The spoilers 52 are made of high thermal conductivity material. A material trough 83 is provided in the middle of the heating plate 51 and the energy storage brick 62 .

[0035] Specifically, when the fireproof cloth enters the heating plate 51, the tension roller 24 keeps the fireproof cloth taut during the transmission process. After the fireproof cloth enters the heating plate 51, the two heating plates 51 evenly heat both sides of the fireproof cloth, and the spoiler 52 makes the heat evenly distributed, so that the fireproof cloth is evenly heated. The fireproof cloth continuously moves downward through the feeding trough 83 between the heating plate 51 and the energy storage brick 62. During the vertical downward transmission of the fireproof cloth, the fireproof cloth will not move left and right due to external force, so that both sides of the fireproof cloth are evenly heated.

[0036] In one embodiment of the present invention, Figure 5 , Figure 6 , Figure 7 As shown, a heat insulating deflector 64 is arranged between the heating plate 51 and the energy storage brick 62, a heat recovery fan 61 is arranged at the feed end of the energy storage brick 62, a capillary heat conduction pipe 65 is arranged inside the energy storage brick 62, the capillary heat conduction pipe 65 is connected to the air outlet end of the heat recovery fan 61, and an air suction pipe 611 is arranged at the air inlet end of the heat recovery fan 61, and the air suction pipe 611 is arranged at the discharge end of the heating plate 51.

[0037] The discharge end of the energy storage brick 62 is provided with a heat insulation board 63 , and an annular gas recovery pipe 651 is provided inside the heat insulation board 63 . The gas recovery pipe 651 is connected to the gas outlet end of the capillary heat conduction pipe 65 , and a feed chute 66 is opened in the middle of the heat insulation board 63 .

[0038] Specifically, the waste heat on the heating plate 51 is slowly transferred downward by the heat recovery fan 61, and the hot air flow is transmitted to the capillary heat pipe 65 through the heat recovery fan 61. The heat in the capillary heat pipe 65 is transferred downward along the energy storage brick 62, so that the waste heat on the heating plate 51 is fully transferred to the energy storage brick 62 for utilization. The temperature of the energy storage brick 62 gradually decreases from top to bottom, so the temperature of the fireproof cloth can slowly decrease in the process of passing through the energy storage brick 62.

[0039] In order to prevent heat accumulation in the energy storage brick 62, the hot air flow in the capillary heat pipe 65 is finally transferred to the outside of the device through the annular gas recovery pipe 651 to maintain the temperature balance in the energy storage brick 62. The bottom of the energy storage brick 62 is isolated from the temperature by the insulation board 63 to prevent the temperature from being transferred to the cooling mechanism 7.

[0040] In one embodiment of the present invention, Figure 3 , Figure 5 As shown, a cooling mechanism 7 is provided on the inner side of the shell bottom 13, and the cooling mechanism 7 is used to fully cool the fireproof cloth after heat treatment. The cooling mechanism 7 includes a blower 75 and a discharge port 131, wherein a bellows 74 is provided inside the shell bottom 13, the blower 75 is provided on the side wall of the shell bottom 13 and is connected to the bellows 74, the discharge port 131 is provided on the side wall of the shell bottom 13 and is connected to the bellows 74, and a spray cooling pipe 76 is provided at the discharge end of the energy storage brick 62.

[0041] Specifically, after the fireproof cloth is slowly cooled by the energy storage bricks 62, it enters the shell bottom 13, and the cold air from the external environment is sent into the shell bottom 13 by the blower 75 to fully cool and transfer the residual heat on the fireproof cloth, and the hot air is transmitted from the discharge port 131 to fully cool the fireproof cloth. The coolant can also be connected to the spray cooling pipe 76 to spray the surface of the fireproof cloth to quickly cool the fireproof cloth.

[0042] In one embodiment of the present invention, Figure 3 , Figure 5 As shown, a second vibrator 71 is disposed on the inner side of the shell bottom 13 , a second vibrator roller 72 is disposed on the output shaft of the second vibrator 71 , and a compaction roller 73 is disposed at the output end of the second vibrator roller 72 .

[0043] Specifically, after the fireproof cloth is fully heat treated by the heating plate 51 and the energy storage bricks 62, it is finally compacted by the second vibration roller 72 to squeeze out the air in the fireproof cloth before it is fully cooled, and the internal fiber structure of the fireproof cloth is more tightly combined by the compaction roller 73.

[0044] In one embodiment of the present invention, Figure 5As shown, an air supply mechanism 8 is provided on the outer shell assembly 1, and the air supply mechanism 8 is used to provide protective gas to the inner side of the outer shell assembly 1. The air supply mechanism 8 includes an air supply pump 81, and the air outlet end of the air supply pump 81 is connected to the inside of the shell top 11. The shell top 11 is provided with an air guide groove 82 for guiding gas.

[0045] Specifically, the heat protection gas is charged into the shell component 1 through the air supply pump 81 to change the heat treatment environment of the fireproof cloth and improve its performance. For example, heat treatment in a nitrogen atmosphere can reduce the oxidation of the fibers in the fireproof cloth and improve its corrosion resistance and mechanical strength; heat treatment in an oxygen atmosphere can promote the curing and distribution uniformity of the flame retardant and improve the flame retardant performance of the fireproof cloth.

[0046] The thermal protection gas is continuously filled into the outer shell assembly 1, which not only provides atmosphere protection for the entire device, but also enables the airflow to flow along the direction of the preheating roller 22, the heating plate 51, and the energy storage brick 62, so that the heat is fully utilized.

[0047] In one embodiment of the present invention, Figure 3 As shown, a feeding mechanism 3 and a receiving mechanism 4 are provided outside the shell component 1, wherein the feeding mechanism 3 is used to release the fireproof cloth that needs heat treatment, and the receiving mechanism 4 is used to recycle the fireproof cloth after heat treatment.

[0048] The feeding mechanism 3 includes a discharge roller 31 and a discharge roller bracket 32, wherein the discharge roller bracket 32 ​​is arranged on the outside of the shell body 12, the discharge roller 31 is arranged on the discharge roller bracket 32, the feeding end of the shell top 11 is provided with a feeding roller 33, and the discharge end of the feeding roller 33 is provided with a material guide scraper 34.

[0049] The receiving mechanism 4 includes a receiving roller bracket 41 and a receiving roller 42 , wherein the receiving roller bracket 41 is arranged on the outer side of the shell body 12 , and the receiving roller 42 is arranged on the receiving roller bracket 41 , and a receiving roller motor 411 for driving the receiving roller 42 to rotate is arranged on the receiving roller bracket 41 .

[0050] Specifically, in the process of feeding the fireproof cloth that needs heat treatment, the fireproof cloth is wound on the discharge roller 31 in advance, or the fireproof cloth that needs heat treatment is directly introduced into the feeding roller 33, and the fireproof cloth is wound on the discharge roller 31 in advance. Figure 3 Feed into the device as shown.

[0051] The fireproof cloth that has been cooled after heat treatment is introduced onto the receiving roller 42, and the receiving roller motor 411 drives the receiving roller 42 to wind and reel the fireproof cloth.

[0052] In order to clearly explain the above embodiments, refer to Figure 1-Figure 7 The specific working principle of the heat treatment device for processing fireproof cloth of the present invention is as follows: When heat treating the fireproof cloth, the fireproof cloth is firstly wound around the discharge roller 31 in advance, or the fireproof cloth to be heat treated can be directly introduced into the feeding roller 33, and then the fireproof cloth is wound around the outer surface of the preheating roller 22 through the preheating introduction roller 26. The fireproof cloth contacts the surface of the preheating roller 22 for preheating. During the preheating process, the heating surface 221 on the surface of the preheating roller 22 is energized to provide an initial temperature for the fireproof cloth, so that the internal temperature of the surface of the fireproof cloth rises rapidly. Then, as the preheating roller 22 continues to rotate, the fireproof cloth is linearly heated after passing through the infrared heating tube 21, so that the heating process of the fireproof cloth is more uniform, and finally the fireproof cloth gradually reaches the temperature required for heat treatment.

[0053] Then, the first vibrator 23 drives the first vibrating roller 231 to rotate and vibrate, and initially vibrates the preheated fireproof cloth, so that the fibers inside the fireproof cloth continuously adjust their positions, thereby promoting the transfer and uniform distribution of heat.

[0054] The preheated fireproof cloth is then tensioned by the tensioning roller 24 and enters the heating plate 51. The heating plate 51 continuously heats the surface of the fireproof cloth to rearrange and crystallize the fiber molecular structure in the fireproof cloth, thereby promoting the combination of the fire retardant and the fiber.

[0055] Then the fireproof cloth continues to transfer downward into the energy storage brick 62. During this process, the waste heat on the heating plate 51 is slowly transferred downward by the heat recovery fan 61. The hot air is transmitted to the capillary heat pipe 65 through the heat recovery fan 61. The heat in the capillary heat pipe 65 is transferred downward along the energy storage brick 62, so that the waste heat on the heating plate 51 is fully transferred to the energy storage brick 62 for use. As the heat in the capillary heat pipe 65 is continuously consumed during the downward transfer, the temperature of the energy storage brick 62 gradually decreases from top to bottom. Therefore, the temperature of the fireproof cloth can slowly decrease during the process of passing through the energy storage brick 62. Prevent the fiber structure from expanding or contracting rapidly and the fire retardant from solidifying rapidly, so that the fiber structure and the fire retardant are slowly cooled and fully combined.

[0056] After the fireproof cloth is slowly cooled by the energy storage bricks 62, it enters the shell bottom 13, and the cold air from the external environment is sent into the shell bottom 13 by the blower 75, so as to fully cool and transfer the residual heat on the fireproof cloth, and the hot air is transmitted out from the discharge port 131, so that the fireproof cloth is fully cooled. Finally, the fireproof cloth that has been cooled after heat treatment is introduced to the receiving roller 42, and the receiving roller motor 411 drives the receiving roller 42 to wind and reel the fireproof cloth.

[0057] In summary, the heat treatment device for processing fireproof cloth in the embodiment of the present invention provides thermal protection for the fireproof cloth during the entire heat treatment process through the outer shell component, slowly heats the fireproof cloth linearly through the preheating mechanism, and then continuously heats the fireproof cloth through the heating mechanism to fully combine the fiber structure and the fire retardant, and then slowly cools the fireproof cloth through the cooling mechanism to reduce the thermal shrinkage rate of the fiber structure in the fireproof cloth, so that the fibers in the fireproof cloth are smoother and denser, and the bonding between the layers of the fireproof cloth is more firmly.

[0058] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
