背景技术 Background technique
梭室窑是洁具生产过程中的一个关键而复杂的热工设备。同时，陶瓷的烧成过程也是一个复杂的物理、化学变化过程，在工艺上分为预热、氧化、弱还原和成瓷四个阶段。因此，陶瓷烧成过程中不仅要对温度、窑压进行有效控制，还要对气氛进行控制。在国内，天然气管道一般都与市政管网连接，存在用气的峰平谷时段，因而燃气压力波动较大。而目前梭室窑供气系统一般都设置了调压稳压站功能，但没有对压力进行分级控制，相对流量也没有监测，因此窑炉运行经常由于操作不当、燃气压力波动等原因，造成能耗高、燃烧效率波动大等影响；同时，产品质量依赖于操作人员的观察和个人经验等。 Shuttle chamber kiln is a key and complex thermal equipment in the production process of sanitary ware. At the same time, the firing process of ceramics is also a complex physical and chemical change process, which is divided into four stages: preheating, oxidation, weak reduction and porcelain formation. Therefore, in the firing process of ceramics, not only the temperature and kiln pressure must be effectively controlled, but also the atmosphere must be controlled. In China, natural gas pipelines are generally connected to the municipal pipeline network, and there are peak and valley periods of gas consumption, so the gas pressure fluctuates greatly. At present, the gas supply system of the shuttle kiln is generally equipped with the function of a pressure regulating and stabilizing station, but the pressure is not controlled in stages, and the relative flow is not monitored. Therefore, the operation of the kiln is often caused by improper operation and gas pressure fluctuations. High energy consumption, large fluctuations in combustion efficiency, etc.; at the same time, product quality depends on the operator's observation and personal experience. the

工作时首先打开法兰球阀2以及其它所有球阀，通过进气管25向该装置通入燃气，经过燃气过滤器3后燃气通过进机械式安全切断阀4，一旦燃气压力超过设定上限，机械式安全切断阀4即会进行切断动作，同时安全溢流阀7也会自动打开进行排空卸压。只有燃气压力符合设定压力要求，燃气才能继续进入到三级调压阀5、二级调压阀20、一级调压阀22。当窑炉启动后，控制主机系统提示必须先进行检漏测试，在检漏测试控制屏按下检漏启动后检漏仪9发出检漏信号，检漏电磁阀14得电打开，对窑炉管道进行通气，并同时检漏仪9激活检漏传感器10进行检漏测试。经过设定的安全泄漏测试时间后，检漏仪9完成检漏后即发送信号关闭检漏电磁阀14并打开放散电磁阀11执行燃气放散。放散结束后检漏仪9即发送信号关闭放散电磁阀11。此时燃气压力装置进入热备状态，检漏仪9反馈检漏通过信号给控制主机进入窑炉烧成运行程序，同时打开切断电磁阀8直至加热过程结束。按烧成工艺，在低温阶段控制主机通过发送信号打开三级电磁切断阀24，通电接通后，调节一级调压阀22以实现一级燃气压力，保证燃烧器工作在低负荷状态，使坯体充分排除水份，缩小窑内局部温差；在中温阶段则通过打开二级电磁切断阀21，延时关断一级调压阀22并调整二级调压阀20以实现二级燃气压力，达到强化窑内氧化气氛，促进坯体排除杂质的烧成工艺效果；在高温瓷化阶段，则通过打开三级电磁切断阀24，延时关闭二级电磁切断阀21，并调整三级稳压阀5实现三级燃气压力。由于所有的燃气都经过智能流量计19，并反馈信号回控制主机系统进行实时检测，实现了压力、流量的自动调节处理、报警提示等功能，有助于调节窑炉燃烧器处于最佳工作状态，确保窑内温度、压力和气氛三大工艺制度的可控稳定，使坯体瓷化完全，提高产品合格率，降低烧成损失。 When working, first open the flange ball valve 2 and all other ball valves, feed gas into the device through the intake pipe 25, and after passing through the gas filter 3, the gas passes through the mechanical safety cut-off valve 4. Once the gas pressure exceeds the set upper limit, the mechanical The safety cut-off valve 4 promptly performs a cut-off action, and simultaneously the safety overflow valve 7 also automatically opens for evacuation and pressure relief. Only when the gas pressure meets the set pressure requirements, can the gas continue to enter the third-stage pressure regulating valve 5, the second-stage pressure regulating valve 20, and the first-stage pressure regulating valve 22. After the kiln is started, the control host system prompts that a leak detection test must be performed first. After pressing the leak detection start on the leak detection test control screen, the leak detector 9 sends a leak detection signal, and the leak detection solenoid valve 14 is energized to open, and the furnace The pipeline is ventilated, and at the same time the leak detector 9 activates the leak detection sensor 10 to perform a leak detection test. After the set safety leak test time, the leak detector 9 sends a signal to close the leak detection solenoid valve 14 and open the release solenoid valve 11 to perform gas release after the leak detection is completed. The leak detector 9 immediately sends a signal to close the bleed electromagnetic valve 11 after the bleed ends. At this time, the gas pressure device enters the hot standby state, and the leak detector 9 feeds back the leak detection pass signal to the control host to enter the kiln firing operation program, and simultaneously opens the cut-off solenoid valve 8 until the heating process ends. According to the firing process, in the low temperature stage, the control host sends a signal to open the three-stage electromagnetic shut-off valve 24. After the power is turned on, the primary pressure regulating valve 22 is adjusted to achieve the primary gas pressure to ensure that the burner works in a low-load state. The green body fully removes moisture and reduces the local temperature difference in the kiln; in the medium temperature stage, the secondary electromagnetic shut-off valve 21 is opened, the primary pressure regulating valve 22 is delayed and the secondary pressure regulating valve 20 is adjusted to achieve the secondary gas pressure. , to strengthen the oxidizing atmosphere in the kiln, and promote the firing process effect of removing impurities from the green body; in the high-temperature porcelain stage, open the third-stage electromagnetic shut-off valve 24, delay closing the second-stage electromagnetic shut-off valve 21, and adjust the third-stage stable Pressure valve 5 realizes three-stage gas pressure. Since all the gas passes through the intelligent flow meter 19, and the feedback signal is sent back to the control host system for real-time detection, automatic adjustment of pressure and flow, alarm prompt and other functions are realized, which helps to adjust the kiln burner to be in the best working state , to ensure the controllability and stability of the three major process systems of temperature, pressure and atmosphere in the kiln, so that the green body can be completely porcelained, the product qualification rate can be improved, and the firing loss can be reduced. the
