Description

Technical Field

[0001] This invention relates to the technical field of long-fiber polyester roofing felt production equipment, and in particular to a novel long-fiber polyester roofing felt shaping, impregnation, and drying equipment. Background Technology

[0002] Polyester roofing felt base fabric: It is a type of non-woven fabric. Polyester roofing felt base fabric is a non-woven fabric product made of 100% polyester fiber through processes such as carding into a web, needle punching reinforcement, and impregnation and shaping. It is cloth-shaped and is the main base of popular waterproof membranes (SBS, APP coating).

[0003] In recent years, my country's long-fiber polyester asphalt felt base fabric project has developed rapidly. Long-fiber polyester asphalt felt base fabric is widely used in industrial and civil waterproofing fields, such as waterproofing and seepage prevention projects for basic construction projects such as residences, highways, high-speed railways, bridges and culverts, and airports.

[0004] Since the national coal-to-gas conversion policy was implemented, most of the polyester roofing felt base fabric industry has adopted gas-fired thermal oil furnaces for heating, with a very small number using a combination of direct combustion and gas-fired thermal oil furnaces. Neither of these two heating methods has eliminated the oil boilers, nor has it solved the problems of low thermal efficiency and safety hazards of thermal oil furnaces. As a result, the cost of long-fiber polyester roofing felt base fabric has increased significantly compared to the coal-fired era, leading to increased costs for downstream industries such as real estate, highways, airports, and railways. At the same time, existing long-fiber polyester roofing felt base fabric shaping, impregnation, and drying production equipment still suffers from problems such as large waste of raw materials, low equipment capacity, high energy consumption, and high pollution.

[0005] Therefore, developing a novel long-fiber polyester felt base fabric shaping, impregnation, and drying device is not only of urgent research value, but also has good economic benefits and industrial application potential. This is the driving force and foundation for the completion of this invention. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art as mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this invention.

[0007] Specifically, the technical problem to be solved by the present invention is to provide a novel long-fiber polyester felt base fabric shaping, impregnation and drying device to solve the problems of low capacity, high energy consumption and high pollution of the current long-fiber polyester felt base fabric shaping, impregnation and drying equipment.

[0008] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0009] A novel long-fiber polyester felt base fabric shaping, impregnation, and drying device includes a fabric feeding machine, a first fabric storage rack downstream of the fabric feeding machine, a shaping oven downstream of the first fabric storage rack, an electrically heated hot rolling mill downstream of the shaping oven, an impregnation machine downstream of the electrically heated hot rolling mill, a direct-fired drying cylinder pre-dryer downstream of the impregnation machine, a drying oven downstream of the direct-fired drying cylinder pre-dryer, a second fabric storage rack downstream of the drying oven, and a winding machine downstream of the second fabric storage rack.

[0010] As an improved solution, the drying oven is installed on top of the support platform, and the shaping oven and the direct-fired drying cylinder pre-dryer are installed at the bottom of the support platform;

[0011] The exhaust port of the shaping oven is connected to the combustion chamber of the drying oven through a first exhaust pipe, and the exhaust port of the direct-fired pre-dryer is also connected to the combustion chamber of the drying oven through a second exhaust pipe.

[0012] As an improved solution, the direct-fired pre-dryer includes a combustion cylinder body, which is mounted on a first support frame. The combustion cylinder body has several exhaust gas discharge holes at both ends along the axial direction. Combustion exhaust gas collection covers are installed at both ends of the combustion cylinder body. Second exhaust gas pipes are installed on the combustion exhaust gas collection covers. The second exhaust gas pipes are connected to the inner cavity of the combustion cylinder body through the exhaust gas discharge holes.

[0013] As an improved solution, the combustion cylinder body has mounting holes along the axial direction, and a fixing sleeve is inserted between the two mounting holes. Burner brackets are arranged and installed on the outer side wall of the fixing sleeve, and burners are installed on each of the burner brackets. The burners are all located close to the inner side wall of the combustion cylinder body.

[0014] The inner cavity of the fixed sleeve is provided with oppositely arranged mixed combustion gas pipes. The two mixed combustion gas pipes pass through the through holes provided on the fixed sleeve and are respectively connected to the air inlet end of the burner.

[0015] As an improved solution, the inner cavity of the fixed sleeve is also provided with an ignition high-voltage wire and a sensor signal transmission line. The ignition high-voltage wire is connected to an igniter, and the igniter is installed on the burner, with the ignition head of the igniter facing the gas outlet of the burner.

[0016] One end of the sensor signal transmission line is connected to a temperature sensor, which is installed in the inner cavity of the combustion cylinder. The other end of the sensor signal transmission line is connected to the main control box, which is connected to a solenoid valve, which is installed on the mixed combustion gas pipeline.

[0017] As an improved solution, the shaping oven adopts one of a direct-fired cylindrical mesh shaping oven and a direct-fired tenter frame shaping oven;

[0018] The drying oven is one of a direct-fired cylindrical mesh drying oven or a direct-fired tenter frame drying oven.

[0019] As an improved solution, the electric heating hot rolling mill includes a second support frame, on which a first hot rolling roll and a second hot rolling roll are rotatably mounted in the vertical direction. The feed end of the electric heating hot rolling mill is provided with a first guide roll, and the discharge end is provided with a second guide roll. The long-fiber polyester felt base fabric at the discharge port of the shaping oven is sequentially wound around the first guide roll, the first hot rolling roll, the second hot rolling roll, and the second guide roll.

[0020] As an improved solution, the dipping machine includes a machine body, on which a dipping tank is provided. A third guide roller is provided at the feed end of the dipping tank. A pair of opposing dipping rollers are rotatably installed in the dipping tank near the third guide roller. A fourth guide roller is provided near the discharge end of the dipping rollers.

[0021] As an improved solution, the top of the impregnation tank is also provided with a uniform coating tank, which is connected to the impregnation tank. Several uniform coating rollers are rotatably installed in the uniform coating tank. The long-fiber polyester felt base fabric passes through the two impregnation rollers and the several uniform coating rollers in sequence and enters the direct-fired drying cylinder pre-dryer for pre-drying.

[0022] After adopting the above technical solution, the beneficial effects of the present invention are:

[0023] By setting the drying oven on top of the support platform and the shaping oven and direct-fired drying cylinder pre-dryer on the bottom of the support platform, and by setting the first exhaust gas pipe and the second exhaust gas pipe, the exhaust gas after combustion of the shaping oven and the direct-fired drying cylinder pre-dryer can be conveniently introduced into the drying oven for secondary utilization, making full use of thermal energy, realizing resource conservation and energy consumption reduction, while also reducing pollution emissions and lowering product costs;

[0024] By installing combustion exhaust gas collection hoods at both ends of the combustion cylinder, the combustion exhaust gas can be easily collected and connected to the drying oven for secondary use through exhaust gas pipes, thus achieving the goal of energy saving and consumption reduction.

[0025] By arranging and installing burner brackets on fixed sleeves, and installing burners on each burner bracket, the burners are all set close to the inner side wall of the combustion cylinder. The side wall of the combustion cylinder can be directly heated by the burners, resulting in fast heat transfer, uniform heat distribution, and high heating efficiency.

[0026] By setting a temperature sensor, the temperature inside the combustion cylinder can be monitored in real time. The temperature sensor is connected to the main control box, and the main control box is connected to the solenoid valve on the mixed combustion gas pipeline. The input of the mixed combustion gas is controlled by the solenoid valve, thereby realizing the regulation of the temperature inside the cylinder.

[0027] By setting up an impregnation tank, long-fiber polyester felt base fabric can be impregnated with adhesive. By setting up a uniform coating tank, and installing a uniform coating roller inside the uniform coating tank, the adhesive on the long-fiber polyester felt base fabric can be evenly applied, improving product quality. At the same time, excess adhesive falls into the uniform coating tank and flows back into the impregnation tank for reuse, reducing resource waste and consumption, and lowering production costs.

[0028] In summary, this invention solves the problems of low capacity, high energy consumption, and high pollution in current long-fiber polyester felt base fabric shaping, impregnation, and drying equipment. Attached Figure Description

[0039] The present invention will be further described below with reference to specific embodiments. However, the uses and purposes of these exemplary embodiments are only for illustrating the present invention and do not constitute any limitation on the actual scope of protection of the present invention, nor are they intended to limit the scope of protection of the present invention to these embodiments.

[0040] Example 1, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, a novel long-fiber polyester roofing felt base fabric shaping, impregnation, and drying device includes a fabric feeding machine 1. The long-fiber polyester roofing felt base fabric exits from the fabric feeding machine 1 for shaping, impregnation, and drying. Downstream of the fabric feeding machine 1 is a first fabric storage rack 2.

Downstream of the drying oven 7 is a second fabric storage rack 8. Downstream of the second fabric storage rack 8 is a winding machine 9. The long-fiber polyester felt base fabric coming out of the unloading machine 1 passes sequentially through the first fabric storage rack 2, the shaping oven 3, the electric heating hot rolling mill 4, the dipping machine 5, the direct-fired drying cylinder pre-dryer 6, the drying oven 7, and the second fabric storage rack 8, and is finally wound up at the winding machine 9.

By setting the first exhaust pipe 11 and the second exhaust pipe 12, the exhaust gas after combustion of the shaping oven 3 and the direct-fired pre-dryer 6 can be conveniently introduced into the drying oven 7 for secondary utilization, making full use of thermal energy, realizing resource conservation and energy consumption reduction, while also reducing pollution emissions and lowering product costs.

[0043] In addition, exhaust fans are installed on both the first exhaust pipe 11 and the second exhaust pipe 12 to draw out the exhaust gas, so that the exhaust gas flows faster after combustion.

[0044] In this embodiment, combined with Figure 2 As shown, the direct-fired pre-dryer 6 includes a combustion cylinder 601, which is mounted on a first support frame 602. Several exhaust gas discharge holes 603 are respectively provided at both ends of the combustion cylinder 601 along its axial direction. Combustion exhaust gas collection hoods 604 are fixedly installed at both ends of the combustion cylinder 601. Second exhaust gas pipes 12 are respectively installed on the combustion exhaust gas collection hoods 604. The second exhaust gas pipes 12 communicate with the inner cavity of the combustion cylinder 601 through the exhaust gas discharge holes 603. By providing combustion exhaust gas collection hoods 604 at both ends of the combustion cylinder 601, the combustion exhaust gas is easily collected and connected to the drying oven 7 for secondary use through the exhaust gas pipes, thus achieving the purpose of energy saving and consumption reduction.

[0045] In this embodiment, the combustion cylinder 601 is modified from a paper drying cylinder as a basic component, and four holes with a radius of 0.25 meters are provided on each end face of the cylinder as exhaust gas outlets 603.

[0046] In this embodiment, combined with Figure 1 and Figure 2 As shown, the combustion cylinder 601 has mounting holes along the axial direction, and a fixing sleeve 13 is inserted between the two mounting holes. Burner brackets 14 are arranged and installed on the outer side wall of the fixing sleeve 13, and burners 15 are installed on each burner bracket 14. The burners 15 are all set close to the inner side wall of the combustion cylinder 601. The side wall of the combustion cylinder 601 can be directly heated through the burners 15. The heat transfer is fast and the heat is evenly distributed, resulting in high heating efficiency.

[0047] The inner cavity of the fixed sleeve 13 is provided with oppositely arranged mixed combustion gas pipes 16. The mixed combustion gas pipes 16 extend into the fixed sleeve 13 from both ends respectively. The two mixed combustion gas pipes 16 pass through the through holes provided on the fixed sleeve 13 respectively and are connected to the air inlet end of the burner 15 respectively to provide mixed combustion gas to the burner 15.

[0048] In this embodiment, combined with Figure 2 and Figure 8 As shown, the inner cavity of the fixed sleeve 13 is also provided with an ignition high voltage wire 17 and a sensor signal transmission line 18. The ignition high voltage wire 17 is connected to the igniter 19. The igniters 19 are respectively installed on the side wall of the burner 15, and the ignition head of the igniter 19 faces the gas outlet of the burner 15.

[0049] One end of the sensor signal transmission line 18 is connected to the temperature sensor 20, which is installed in the inner cavity of the combustion cylinder 601, specifically on the burner bracket 14. The other end of the sensor signal transmission line 18 is connected to the main control box 21. The main control box 21 is connected to the solenoid valve 22 via a line. The solenoid valve 22 is installed on the mixed combustion gas pipeline 16. By setting the temperature sensor 20, the temperature inside the combustion cylinder 601 can be monitored in real time. The main control box 21 is connected to the solenoid valve 22, which can control the input amount of mixed combustion gas, thereby achieving the regulation of the temperature inside the cylinder.

[0050] In addition, an alarm 23 is installed on the control box. When the temperature detected by the temperature sensor 20 exceeds the set maximum temperature value, the alarm 23 will sound an alarm to promptly remind the staff to intervene manually to cool down the temperature and avoid damage to the long-fiber polyester felt base fabric due to excessive temperature.

[0051] In addition, temperature sensors 20 are also installed in the shaping oven 3 and the drying oven 7, and the temperature sensors 20 are also connected to the main control box 21.

[0052] In this embodiment, combined with Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the shaping oven 3 adopts one of the following: direct-fired cylindrical mesh shaping oven 301 and direct-fired tenter frame shaping oven 302;

[0053] The drying oven 7 adopts one of the following: direct-fired circular mesh drying oven 701 and direct-fired tenter frame drying oven 702.

[0054] In this embodiment, combined with Figure 3As shown, the electric heating hot rolling mill 4 includes a second support frame 401. The second support frame 401 is rotatably mounted with a first hot rolling roll 402 and a second hot rolling roll 403 in the vertical direction. The feed end of the electric heating hot rolling mill 4 is provided with a first guide roll 404, and the discharge end is provided with a second guide roll 405. The long-fiber polyester felt base cloth at the discharge port of the shaping oven 3 is sequentially wound around the first guide roll 404, the first hot rolling roll 402, the second hot rolling roll 403, and the second guide roll 405.

[0055] In this embodiment, combined with Figure 4 As shown, the impregnation machine 5 includes a machine body 501, an impregnation tank 502 on the machine body 501, a third guide roller 503 at the feed end of the impregnation tank 502, a pair of oppositely arranged impregnation rollers 504 rotatably mounted in the impregnation tank 502 near the third guide roller 503, and a fourth guide roller 505 near the discharge end of the impregnation rollers 504. The long-fiber polyester felt base fabric passes around the third guide roller 503 and through the two impregnation rollers 504 for impregnation.

[0056] In this embodiment, combined with Figure 4 As shown, the top of the impregnation tank 502 is also provided with a uniform coating tank 506, which is connected to the impregnation tank 502. Several uniform coating rollers 507 are rotatably installed in the uniform coating tank 506. The long-fiber polyester felt base fabric passes through the two impregnation rollers 504 and the several uniform coating rollers 507 in sequence, and enters the direct-fired drying cylinder pre-dryer 6 for drying. The uniform coating rollers 507 can evenly coat the glue on the long-fiber polyester felt base fabric, improving product quality. At the same time, excess glue falls into the uniform coating tank 506 and flows back into the impregnation tank 502 through the uniform coating tank 506 for reuse, reducing resource waste and consumption and lowering production costs.

[0057] In this embodiment, as Figure 1 As shown, a novel long-fiber polyester felt base fabric shaping, impregnation and drying device is described. The shaping oven 3 is a direct-fired round mesh shaping oven 301, and the drying oven 7 is a direct-fired round mesh drying oven 701.

[0058] Example 2, as Figure 5 As shown, a novel long-fiber polyester felt base fabric shaping, impregnation and drying device is the same as that in Example 1, except for the following differences. In this example, the shaping oven 3 is a direct-fired cylindrical mesh shaping oven 301, and the drying oven 7 is a direct-fired tenter drying oven 702.

[0059] Example 3, as Figure 6As shown, a novel long-fiber polyester felt base fabric shaping, impregnation and drying device is the same as that in Example 1, except for the following differences.

[0060] Example 4, as Figure 7 As shown, a novel long-fiber polyester felt base fabric shaping, impregnation and drying device is the same as that in Example 1, except for the following differences. In this example, the drying oven 7 is a direct-fired tenter drying oven 702.

[0061] For ease of understanding, the working process of this embodiment is described below:

[0062] like Figures 1-8 As shown, the long-fiber polyester felt base fabric coming out of the fabric feeding machine 1 passes through the first fabric storage rack 2 and enters the shaping oven 3 for shaping and drying. After shaping, the long-fiber polyester felt base fabric enters the electric heating hot rolling mill 4 for surface heat treatment. After surface heat treatment, the long-fiber polyester felt base fabric enters the impregnation machine 5 for impregnation. During the impregnation process, the long-fiber polyester felt base fabric first passes through a pair of impregnation rollers 504, and then passes through several uniform coating rollers 507 for uniform coating, so that the excess glue on the surface of the long-fiber polyester felt base fabric flows back into the impregnation tank 502.

[0063] The long-fiber polyester felt base fabric that has been impregnated with styrene enters the direct-fired drying cylinder pre-dryer 6 for pre-drying treatment. After pre-drying, it enters the drying oven 7 for complete drying treatment. Then it passes through the second fabric storage rack 8 and is finally wound up on the winding machine 9.

[0064] Meanwhile, the exhaust gases from combustion in the direct-fired pre-dryer 6 and the shaping oven 3 enter the drying oven 7 through the second exhaust gas pipe 12 and the first exhaust gas pipe 11, respectively, and are reused.

[0065] In summary, this invention solves the problems of low capacity, high energy consumption, and high pollution in current long-fiber polyester felt base fabric shaping, impregnation, and drying equipment.
