[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The accessory device for the split slag lock valve of a gasifier according to an embodiment of the present invention comprises: a movable support platform, a pneumatic control module 1 and an air intake source pipe 2 .

[0026] The pneumatic control module 1 is integrated on the movable support platform. The pneumatic control module 1 includes a pressure reducing valve 11, a solenoid valve 12 and a pneumatic control valve 13 which are connected in sequence. The air inlet of the pressure reducing valve 11 is used to be connected to the instrument air outlet. The first end of the air inlet source pipe 2 is connected to the pneumatic control valve 13, and the second end of the air inlet source pipe 2 is connected to the actuator cylinder 100.

[0027] Specifically, Figure 1 As shown, the movable support platform is the basic structure of the bearing device, providing a platform for the accessory device to be easily disassembled and moved. The pressure reducing valve 11, the solenoid valve 12 and the air control valve 13 are connected in sequence to form a core control unit for pneumatically controlling the actuator cylinder 100. The air inlet source pipe 2 is a flexible pipe connecting the air control valve 13 and the actuator cylinder 100 to facilitate installation and disassembly.

[0028] It is understandable that the pneumatic control module 1 (pressure reducing valve 11 → solenoid valve 12 → air control valve 13) is fixed on a movable support platform, the air inlet of the pressure reducing valve 11 is connected to the external instrument air, and the air control valve 13 is connected to the actuator cylinder 100 through the air intake source pipe 2. In other words, all pneumatic components are integrated on the mobile platform, and there is no need to disassemble the accessories one by one during maintenance, which reduces the disassembly and assembly time and the risk of joint damage. When maintenance is required, quick disassembly and assembly can be achieved, that is, only the air intake source pipe 2 and the solenoid valve 12 wiring need to be disconnected to move the device, thereby significantly improving the maintenance efficiency. In addition, the mobile bracket supports multiple valves to share the same accessory device, reducing the cost of spare parts.

[0029] In other words, the accessory device for the split slag lock valve of the gasifier in the embodiment of the present invention integrates the traditional dispersed installation accessories into a movable device to solve the problem of cumbersome disassembly and assembly. In addition, different functional modules can be selected for pneumatic actuators of different specifications to meet different functional requirements. The use of pneumatic actuator control component integration vehicles under some harsh working conditions such as high temperature and strong vibration can keep the control components away from high temperature, strong vibration and other working conditions, greatly extend the service life of each control component, reduce the frequency of disassembly and assembly of accessories, and reduce the waste of manpower and material resources.

[0030] In some embodiments, the pneumatic control module 1 further includes a flow regulating valve 14 , which is connected to the movable support platform and installed between the pressure reducing valve 11 and the solenoid valve 12 .

[0031] It is understandable that if Figure 1 As shown, the flow regulating valve 14 is installed between the pressure reducing valve 11 and the solenoid valve 12, that is, the flow regulating valve 14 is installed downstream of the pressure reducing valve 11 in series so as to be used to regulate the gas flow entering the solenoid valve 12, thereby realizing the flow regulating function.

[0032] That is to say, the accessory device for the split slag lock valve of the gasifier in the embodiment of the present invention can optimize the cylinder action speed by adjusting the flow rate, thereby avoiding impact wear caused by too fast valve opening and closing. It can also be dynamically adjusted according to different working conditions (such as air pressure fluctuations) to improve system stability.

[0033] In some embodiments, the pneumatic control module 1 further includes a speed regulating device 15 , which is connected to the movable support platform and installed between the solenoid valve 12 and the pneumatic control valve 13 .

[0034] It is understandable that the speed regulating device 15 is installed between the solenoid valve 12 and the air control valve 13. The speed regulating device 15 can be placed in series at the output end of the solenoid valve 12 to control the air intake rate of the air control valve 13. In other words, due to the existence of the speed regulating device 15, the valve can be opened and closed smoothly by limiting the air flow speed. In addition, the speed regulating device 15 can also be used to reduce the vibration of the cylinder during movement to avoid loosening or air leakage of the pipeline.

[0035] In some embodiments, the speed regulating device 15 includes a speed regulating detection component and a speed regulating control component. The speed regulating detection component is used to detect the flow rate between the solenoid valve 12 and the air control valve 13. The speed regulating control component is connected to the air control valve 13 to adjust the air intake size of the air control valve 13 according to the flow rate between the solenoid valve 12 and the air control valve 13.

[0036] It is understandable that the speed regulating detection component is used to detect the gas flow rate between the electromagnetic valve 12 and the gas control valve 13 (such as a flow sensor), and the speed regulating control component is electrically connected to the speed regulating detection component so that the speed regulating control component can be regulated according to the detection data transmitted by the speed regulating detection component. The speed regulating control component can use a proportional valve to enable the speed regulating detection component to monitor the flow rate between the electromagnetic valve 12 and the gas control valve 13, and the speed regulating control component adjusts the opening of the gas control valve 13 according to the feedback signal. In other words, the speed regulating device 15 can be used to provide real-time feedback and regulation to ensure a constant flow rate and adapt to different load requirements. Reduce manual intervention and reduce the risk of operational errors.

[0037] In some embodiments, the pneumatic control module 1 further includes a position-holding device 16 , which is connected between the pneumatic control valve 13 and the actuator cylinder 100 .

[0038] It is understandable that the position-holding device 16 is arranged in series at the output end of the gas control valve 13 to monitor and maintain the cylinder position. That is, when the gas circuit fails (such as pressure loss), the cylinder position is locked, and the position-holding device 16 can be used to prevent the valve from malfunctioning, so as to avoid accidental closure of the valve due to gas pressure fluctuations, thereby ensuring continuous operation of the system.

[0039] In some embodiments, the position-holding device 16 includes a position-holding control element, which is used to detect the air pressure between the air-controlled valve 13 and the actuator cylinder 100 and control the on-off of the air-controlled valve 13 according to the air pressure information.

[0040] It is understandable that the position-holding control component may include an air pressure sensor and a logic control unit. The position-holding control component detects the air pressure between the air control valve 13 and the cylinder, and controls the on and off of the air control valve 13 according to the threshold. In other words, the position-holding device 16 has an automatic protection function, that is, when the position-holding control component detects an abnormal air pressure (such as a leak), the air circuit is immediately cut off and an alarm is sounded. This can reduce manual inspections and reduce maintenance costs through automatic monitoring.

[0041] In some embodiments, the solenoid valve 12 is a two-way parallel solenoid valve 12, the air-controlled valve 13 includes multiple air-controlled valve 13 groups, and each air-controlled valve 13 group includes multiple air-controlled valves 13, and the multiple air-controlled valve 13 groups are connected in parallel.

[0042] It can be understood that the dual solenoid valves 12 control the opening / closing of the gas circuit respectively, and the gas control valves 13 are connected in parallel for redundancy. That is to say, when a single circuit fails during use, the backup gas circuit can still work, that is, the solenoid valves 12 and the gas control valves 13 are connected in parallel, which improves the reliability and redundancy of the system, enhances the overall control ability, and also improves the system fault tolerance. In addition, the use of parallel gas control valves 13 can also share the air flow pressure and extend the life of the components.

[0043] In some embodiments, the air intake source pipe 2 is a flexible hose, and the working pressure range of the air intake source pipe 2 is 0.6-1.2 MPa, and the temperature resistance level reaches above 120°C.

[0044] It is understandable that the air intake source pipe 2 uses a flexible hose with a specific working pressure and temperature resistance level, which can improve the overall flexibility of the connecting pipeline so as to adapt to different installation environments and ensure safe operation under high temperature and high pressure conditions. Optionally, the two ends of the air intake source pipe 2 can be connected to the air control valve 13 and the cylinder through quick-change connectors to ensure quick disassembly and assembly, and avoid bending damage during disassembly and assembly.

[0045] In some embodiments, the movable support platform includes a load-bearing frame, a movable roller assembly and a mounting panel. The load-bearing frame is formed by welding metal profiles, and the movable roller assemblies are arranged at the four corners of the bottom of the frame.

[0046] It is understandable that the load-bearing frame can be welded with angle irons, and the movable roller assembly is arranged at the bottom of the load-bearing frame to provide the entire accessory device with movable capability. The pneumatic control module 1 can be fixed to the mounting panel by bolts or plug-in, clip-on, etc. In other words, the metal frame has a strong load-bearing capacity and can prevent deformation during transportation. The four-wheel design can adapt to narrow spaces and reduce the intensity of manual handling.

[0047] Optionally, the mobile roller assembly includes universal wheels and fixed wheels. That is, the universal wheels (with brake function) are used for flexible steering, and the fixed wheels can provide straight-line stability. The brake mechanism prevents the device from sliding and ensures reliable fixation during maintenance. The universal wheels move flexibly on the workshop floor, and the fixed wheels reduce deviation.
