Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection of oil cleaning machines, and particularly relates to a dual-control fire extinguishing device for a cleaning machine. Background Art

[0002] The flash point of the cleaning oil is 40°C, which has a low flash point and is flammable and volatile. During the production process, a large amount of oil mist will be generated around the equipment, and the explosion limit is 1.1-8.7%, so there is a risk of fire and explosion. Generally speaking, the main factors causing equipment fires are: 1 Local friction high temperature: Dry friction without lubrication of bearings such as motors and rollers, and mechanical vibration friction may generate local high temperature during high-speed operation, exceeding the oil flash point. 2 Open fire and electric sparks: Sparks generated by abnormal friction such as knocking and hitting of iron tools, and breaking of belts and swinging of tails; Electric sparks generated by electrical short circuits and arcing. 3 Static electricity: In dry seasons, the human body and equipment are easily charged with static electricity and suffer electric shocks, with voltages as high as tens of thousands of volts, and sparks are generated when discharging.

[0003] Therefore, a fire protection system is set up in the workshop where the cleaning machine is located. The existing fire protection system generally has a detection module for detecting fire, and then the controller is used to open the valve to make carbon dioxide pass through the spray pipeline for fire extinguishing. However, in case of sudden problems such as damage to the detection module and rust of the valve, the fire protection system cannot be opened, which will cause the fire to spread and form a fire.

[0004] Therefore, there is an urgent need for a dual-control fire extinguishing device to set multiple fire extinguishing triggers and improve the reliability of the fire extinguishing system. Summary of the Invention

[0005] In order to solve the problem of poor reliability of the existing fire extinguishing system for cleaning machines, the utility model provides a dual-control fire extinguishing device for a cleaning machine, which is provided with two groups of nitrogen release control valve modules. The two groups of nitrogen release control valve modules are connected in parallel, and the fire protection system realizes dual-valve on-line control, thereby improving the reliability of the fire extinguishing system.

[0006] To achieve the above object, the utility model provides a dual-control fire extinguishing device for a cleaning machine, which includes a spray pipeline, a carbon dioxide bottle group, a detection module and a controller. The carbon dioxide bottle group is communicated with the spray pipeline. The detection module is arranged near the top end of the spray pipeline and fixed to the spray pipeline. The spray pipeline is arranged above the cleaning machine. The detection module is communicatively connected with the controller. The controller is connected with an operation panel. A first connecting pipeline is arranged between the carbon dioxide bottle group and the spray pipeline. The first connecting pipeline is provided with a first nitrogen release control valve module. The first nitrogen release control valve module is electrically connected with the controller;

[0007] A second connecting pipe is also provided between the carbon dioxide cylinder group and the spray pipe. The second connecting pipe is provided with a second nitrogen release control valve module, and the second nitrogen release control valve module is electrically connected to the controller;

[0008] The operation panel is provided with an emergency stop button and a start button, and the emergency stop button and the start button are connected to the input end of the operation panel.

[0009] Further, the first nitrogen release control valve module includes a first nitrogen release control valve, the second nitrogen release control valve module includes a second nitrogen release control valve, nitrogen cylinders are connected to both the first nitrogen release control valve and the second nitrogen release control valve, and an electric head valve is arranged between the nitrogen cylinders and the first nitrogen release control valve and the second nitrogen release control valve.

[0010] Further, the electric head valve includes a solenoid valve, the solenoid valve includes a valve body and a coil, and the coil is electrically connected to the output end of the controller.

[0011] The first nitrogen release control valve module and the second nitrogen release control valve module have the same structure. The first nitrogen release control valve module and the second nitrogen release control valve module are respectively connected in parallel with the carbon dioxide cylinder group and the spray pipe through the first connecting pipe and the second connecting pipe, and both of them work simultaneously during operation.

[0012] Further, the carbon dioxide cylinder group includes a plurality of carbon dioxide cylinders, and a head valve is arranged on the carbon dioxide cylinders.

[0013] Even if the first nitrogen release control valve and the second nitrogen release control valve fail, manual fire extinguishing operation can be carried out by opening the head valve arranged on the carbon dioxide cylinder.

[0014] Further, the detection module includes a smoke sensor, and the output end of the smoke sensor is electrically connected to the input end of the controller. A large amount of smoke will be generated when a fire breaks out in the workshop, and the smoke sensor can effectively detect the fire.

[0015] Further, the operation panel includes an HMI module, and an RS458 communication module is arranged between the HMI module and the controller. The HMI module has a high degree of intelligence and is convenient for communication. The HMI module and the controller adopt the RS458 communication module, which can realize the remote communication between the two.

[0016] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0017] The utility model adopts a dual - control fire - extinguishing mechanism, effectively improving the reliability of the fire - extinguishing system. The detection module is communicatively connected to the controller. A first connecting pipe and a second channel are arranged between the carbon dioxide cylinder group and the spray pipe. A first nitrogen release control valve module is arranged on the first connecting pipe, and a second nitrogen release control valve module is arranged on the second connecting pipe. When a fire breaks out, the controller controls the first nitrogen release control valve module and the second nitrogen release control valve module to work simultaneously. Compared with setting one control valve for control, the reliability of the fire - extinguishing system is effectively improved.

[0018] If the detection module does not respond when there is a fire. At this time, a start signal is sent to the controller by operating the start button on the operation panel, and then the controller controls the first nitrogen release control valve module and the second nitrogen release control valve module to work.

[0019] If the remote control fails to respond, the staff come to the scene and manually open the first nitrogen release control valve module or the second nitrogen release control valve module to achieve fire - extinguishing operations. Description of the Drawings

[0027] The operation panel 5 is provided with an emergency stop button 11 and a start button 12, and the emergency stop button 11 and the start button 12 are connected to the input end of the operation panel 5.

[0028] The first nitrogen release control valve module includes a first nitrogen release control valve 7, the second nitrogen release control valve module includes a second nitrogen release control valve 10, the first nitrogen release control valve 7 and the second nitrogen release control valve 10 are both connected to a nitrogen cylinder 8, and an electric head valve is arranged between the nitrogen cylinder 8 and the first nitrogen release control valve 7 and the second nitrogen release control valve 10.

[0029] The electric head valve includes an electromagnetic valve, and the electromagnetic valve includes a valve body and a coil, and the coil is electrically connected to the output end of the controller 4.

[0030] The carbon dioxide cylinder group 2 includes a plurality of carbon dioxide cylinders, and a head valve is arranged on the carbon dioxide cylinders.

[0031] The detection module 3 includes a smoke sensor, and the output end of the smoke sensor is electrically connected to the input end of the controller 4.

[0032] The operation panel 5 includes an HMI module, and an RS458 communication module is arranged between the HMI module and the controller 4.

[0033] In this embodiment, the controller 4 is selected as a PLC controller. As Figure 1 shown, the first connecting pipe 6 and the second connecting pipe 9 are similar in structure, and both include a main pipe, a plurality of first branch pipes and a plurality of second branch pipes. The main pipe has an H-shaped structure, and a plurality of first branch pipes and a plurality of second branch pipes are respectively arranged on both sides of the main pipe. The first branch pipes are connected to the carbon dioxide cylinders, and the second branch pipes are connected to the spray pipe 1. The spray pipe 1 includes a nozzle and a pipe.

In Figure 1 the electrical control wire is a dotted line.

[0034] During operation, the detection module 3 detects a fire. If a fire occurs, a large amount of smoke will be generated in the workshop. The number of detection modules 3 is multiple, and the multiple detection modules 3 are evenly distributed above the workshop and perform detections respectively. After the detection module 3 detects a fire, it sends a level information signal to the controller 4, and the controller 4 controls the electromagnetic valve between the first nitrogen release control valve 7 and the nitrogen cylinder 8 ( Figure 2When the coil of the first nitrogen release control valve (K1) is energized, the first nitrogen release control valve 7 is activated, and the carbon dioxide cylinder group 2 is connected to the sprinkler pipeline 1 through the first connecting pipeline 6 to carry out fire extinguishing operations.
