Description

Technical Field

[0001] The invention belongs to the technical field of polyester mesh monofilament production, and particularly relates to a multi-layer heat-setting device and a heat-setting process for producing polyester mesh monofilament. Background Art

[0002] Polyester mesh is one of the main drying and filtering materials. There are many processes in the production of polyester mesh, among which heat setting is a very important final process in the production of polyester mesh. The difference in the heat setting quality of polyester mesh monofilament directly determines whether the net is finally qualified or not.

[0003] There are many types of heat setting devices available at present, such as the existing public document CN218404726U-A polyester gabion mesh electric heating setting device, which is publicly provided with a heating box, short plates are welded on both sides of the heating box, one side of the short plate is connected to a support roller through a bearing movably embedded, lifting components are installed on both sides of the heating box, and a pressure roller is installed on the surface of the lifting component, a heater is fixedly installed on the back of the inner cavity of the heating box, a temperature sensor is fixedly installed on the right side of the top of the inner cavity of the heating box, and a guide roller is movably embedded in the bottom of the back of the inner cavity of the heating box through a bearing. Although it can be used for polyester mesh heat setting, it still has the following disadvantages in actual use: 1. In the public document CN218404726U, a polyester gabion mesh electric heating setting device is disclosed. When the polyester mesh monofilaments are dried, the monofilaments closer to the heating rotor are prone to over-drying, and the monofilaments farther from the heating rotor are prone to under-drying, resulting in uneven drying of the monofilaments and unsatisfactory heat setting effect.

[0004] 2. Different types of polyester, such as PET, PTT, PBT, etc., have different molecular structures and properties, different heat setting effects, and different required temperatures. However, existing heat setting boxes can usually only be used as single-layer spaces. For example, a polyester gabion mesh electric heating setting device disclosed in the public document CN218404726U has low space utilization and cannot meet the production requirements of heat setting polyester monofilament meshes of different types and different temperature requirements at the same time. If it is necessary to meet the production requirements of heat setting polyester monofilament meshes of different types and different temperature requirements at the same time, multiple heat setting boxes need to be set up and used simultaneously.

[0005] 3. Polyester itself is a flammable material, so the temperature needs to be precisely controlled during the heat setting process. If the temperature control system fails, such as the temperature sensor failure or the thermostat failure, the heating equipment will continue to heat the polyester mesh filaments, causing the temperature to far exceed the temperature required for normal heat setting and reach the ignition point of polyester, which can easily cause a fire. In addition, if the heating equipment is unevenly heated, the polyester mesh filaments will be locally overheated. Excessive local temperature will also cause the polyester mesh filaments to burn. Once the polyester mesh filaments catch fire, it is easy to ignite these flammable materials and expand the fire, posing a great safety hazard.

[0006] To this end, we provide a multi-layer heat setting device and heat setting process for producing polyester mesh monofilaments to solve the above-mentioned problems. Summary of the invention

When the heat setting box is used in multiple layers, if the polyester monofilament mesh between the two guide pipe mechanisms catches fire due to high temperature, the inert gas in the gas tanks on both sides of the fire area will be discharged synchronously from the gas nozzles on both sides of the fire area, so that the inert gas quickly and accurately fills the fire area, thereby achieving the purpose of small-area fire extinguishing. If the temperature detected by each temperature sensor exceeds the set threshold, the inert gas in each gas tank will be sprayed out immediately, so that the inert gas quickly fills the entire heat setting box, thereby achieving the purpose of large-area fire extinguishing. It can accurately and quickly extinguish a specific small area, and can also quickly extinguish a large area. When the heat setting box is used in multiple layers, it can also quickly extinguish the internal space of a specific box layer, and after the fire is extinguished, the exhaust gas in the heat setting box can be discharged to the gas filter box through the exhaust pipe mechanism for treatment, thereby improving the safety and environmental protection of production.

The connecting pipes of each air pump 232 in a row of guide pipe mechanisms 200 are connected to the U-shaped main pipes of the corresponding exhaust pipe mechanism 500. The U-shaped main pipes of each exhaust pipe mechanism 500 are connected to each air inlet of the gas filter box 101 through their own delivery pipes.

[0045] The operation process of this embodiment is as follows: during normal use, if the polyester monofilament mesh 600 between the two guide pipe mechanisms 200 catches fire due to high temperature, the flame sensor 120 between the two guide pipe mechanisms 200 immediately transmits the monitoring signal to the controller of the external control cabinet, and the air pump 232 of the guide pipe mechanisms 200 on both sides of the fire area is immediately started through the controller of the external control cabinet, and the solenoid valve 233 between the air pump 232 and the gas tank 240 and the solenoid valve 233 between the air pump 232 and the inner tube 220 are opened at the same time, and the inert gas inside the gas tank 240 is transported to the inner tube 220 through the air pump 232, and is simultaneously discharged from each gas nozzle of the inner tube 220 in the guide pipe mechanisms 200 on both sides of the fire area, so that the inert gas quickly and accurately fills the fire area, achieving the purpose of small-area fire extinguishing; If the heat setting box 100 is used as a single layer, when the temperature detected by each temperature sensor 140 exceeds the set threshold, the controller of the external control cabinet will automatically start the air pump 232 of each guide tube mechanism 200, and simultaneously open the solenoid valve 233 between each air pump 232 and the gas tank 240 and the solenoid valve 233 between each air pump 232 and the inner tube 220, and the inert gas inside the gas tank 240 is transported to the inner tube 220 through the air pump 232, and then discharged from each gas nozzle of each inner tube 220, so that the inert gas quickly fills the entire heat setting box 100, so as to achieve the purpose of large-area fire extinguishing; If the heat setting box 100 is used in multiple layers, when the temperature detected by the temperature sensor 140 of the corresponding box layer exceeds the set threshold, the controller of the external control cabinet will automatically start the air pump 232 of each guide pipe mechanism 200 of the corresponding box layer, and simultaneously open the solenoid valve 233 between each air pump 232 and the gas tank 240 of the corresponding box layer and the solenoid valve 233 between each air pump 232 and the inner tube 220 of the corresponding box layer, and the inert gas inside the gas tank 240 is transported to the inner tube 220 through the air pump 232, and then discharged from each gas nozzle of each inner tube 220, so that the inert gas quickly fills the internal space of the corresponding box layer in the heat setting box 100, so as to achieve the purpose of extinguishing the fire in the specific box layer; After the preset fire extinguishing time, the controller of the external control cabinet will automatically start the air pump 232 of each guide pipe mechanism 200, and at the same time open the solenoid valve 233 on the connecting pipe of the air pump 232 and open the solenoid valve 233 between the air pump 232 and the inner pipe 220. Through the air pump 232, the exhaust gas generated by the fire in the heat setting box 100 is sucked into the inner pipe 220, and discharged to the gas filter box 101 through the connected exhaust pipe mechanism 500, and then discharged from the outlet of the gas filter box 101 after being processed by the gas filter box 101.
