Description

Technical Field

[0001] The utility model relates to the field of safe feeding devices for chemical production, in particular to a safe feeding device for chemical production. Background Art

[0002] In modern life, many items are made by mixing unused chemical raw materials through chemical production. Some of the raw materials used in chemical production are dangerous. Usually in the production feeding process, gas or liquid raw materials are transported through sealed pipes, isolated from the outside world, and will not cause danger. However, when the feed pipe has cracks due to improper connection, excessive load or aging, the chemical raw materials in the pipe leak to the outside world uncontrollably, or cause fire, or cause explosion, etc., threatening production safety.

[0003] In order to deal with the dangerous situation caused by the leakage of liquid chemical raw materials from the feed pipeline during production, generally after the leakage occurs, the corresponding sensor will transmit a signal to close the corresponding pipe valve to prevent further leakage and expansion. For the raw materials that have leaked and flowed to the ground, dry powder, foam or carbon dioxide fire extinguishers are used to isolate or extinguish the fire. Such emergency measures still have shortcomings: 1. Due to production needs and site limitations, many chemical processing sites currently use many feed pipelines stacked layer by layer. The leaked liquid chemical raw materials will drip onto other pipelines or equipment facilities below when they flow to the ground, causing pollution. After contacting with some specific substances, it may also cause Some chemical reactions are dangerous. After flowing to the ground, they will overflow, and it is difficult to carry out fire fighting and recycling in corners; 2. Fire fighting or sprinkler systems for spraying fire extinguishing and isolating materials are generally built on the ceiling of the workshop and combined with handheld fire extinguishers. The sprinkler system above the workshop may not be able to completely cover all areas in the space, so there will be blind spots, resulting in the inability to effectively and timely cut off the dangerous source of leakage. Handheld fire extinguishers also need to be manually held and close to the leaked raw materials. The raw materials may have dangerous characteristics such as flammable and explosive, highly corrosive or toxic volatility, which is also a threat to fire safety personnel; therefore, a safe feeding device for chemical production is needed.

DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Embodiment 1

[0027] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 In order to solve the above technical problems, the technical solution provided by the utility model is: a safe feeding device for chemical production, including a feeding pipeline 2, which is a transportation pipeline for feeding liquid raw materials during chemical production. A bracket 11 is connected to the outer side of the feeding pipeline 2 to support various mechanisms and components in the device. The device can be spliced ​​in multiple groups through the bracket 11, which is suitable for safe leakage protection of multiple feeding pipelines in a certain area.

[0028] The support 11 is located below the feed pipe 2 and is connected to a leakproof groove 1 for catching the liquid chemical raw materials dripping after the feed pipe 2 leaks, so as to prevent them from flowing to the outside and causing pollution and potential safety hazards. The bottom of the leakproof groove 1 is connected downwardly with a plurality of infusion pipes 7 for making the liquid raw materials caught by the leakproof groove 1 flow out of the leakproof groove 1 and enter the collecting pipe 10 for unified treatment. A collecting funnel 8 is connected between the leakproof groove 1 and the top of the infusion pipe 7 to facilitate the chemical raw material liquid in the leakproof groove 1 to flow into the infusion pipe 7 and out. Drainage elbows 9 are connected on both sides of the bottom end of the liquid pipe 7. On the one hand, it is convenient for the liquid in the infusion pipe 7 to automatically flow into the collecting pipe 10 due to the gravity effect. On the other hand, this shape design is convenient for the device to be stacked up and down without occupying the installation space of the device unit on the lower layer. The bottom end of the bracket 11 is connected on both sides with a collecting pipe 10 whose top is connected to the drainage elbow 9, which is used to uniformly receive and discharge leaked liquid raw materials. The bottom end of the bracket 11 is connected on both sides with a pipe rack 12 that matches the collecting pipe 10, which is used to support and fix the collecting pipe 10 on the bracket 11.

[0029] Embodiment 2

[0030] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 The top of the bracket 11 is located above the feed pipeline 2, and spray water pipes 14 are connected on both sides for providing and transporting liquid for making fire extinguishing isolation foam, that is, foam liquid. Pipe racks 15 matching the spray water pipes 14 are connected on both sides of the top of the bracket 11, and are used to support and fix the spray water pipes 14 on the bracket 11. The top of the spray water pipe 14 is connected upward with a plurality of water supply pipes 18, through which the spray water pipe 14 obtains the foam liquid supply of the water injection pipe, and is used to supply water or corresponding fire extinguishing isolation liquid to the spray water pipe 14. The spray water pipe 14 is connected to a plurality of connecting pipes 16 on the side close to the feed pipeline 2, and the connecting pipes 16 are arranged obliquely downward. The connecting pipes 16 are connected to a foam nozzle 17 at one end away from the spray water pipe 14, which is used to spray foam toward the feed pipeline 2 to prevent the occurrence or spread of fire and other disasters.

[0031] Embodiment 3

[0032] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 5The bottom of the leak-proof groove 1 is upwardly connected to a plurality of support frames 3 that cooperate with the material delivery pipeline 2, which are used to support the material delivery pipeline 2 in the leak-proof groove 1. The two sides of the leak-proof groove 1 are inwardly connected to a plurality of fastening blocks 4 that cooperate with the material delivery pipeline 2, which are used to clamp the material delivery pipeline 2 from both sides. The fastening blocks 4 are connected to a buffer spring 5 to prevent the material delivery pipeline 2 from being fixed too tightly in the leak-proof groove 1. When some collisions may occur, the material delivery pipeline 2 is subjected to excessive force and cannot be released, thereby causing cracks, thereby causing leakage of liquid raw materials inside the material delivery pipeline. The fastening block 4 is connected to a rubber pad 6 at one end away from the leak-proof groove 1 to enhance the friction between the fastening block 4 and the outer wall of the material delivery pipeline 2. The bottom of the leak-proof groove 1 is upwardly connected to a plurality of flow sensors 13, which are used to detect the leakage in time and issue an alarm when chemical liquid raw materials leak in the material delivery pipeline 2 and the raw materials flow onto the leak-proof plate, and start the corresponding safety mechanism components to enter the protective operation state.

[0033] During the specific implementation of the utility model, when the feed pipe 2 equipped with the device for feeding leaks liquid chemical raw materials, the liquid raw materials leaking out of the feed pipe 2 due to various reasons flow out from the pipe wall and drip, and the raw materials flowing down are blocked by the anti-leakage groove 1 below, and will not spill on the ground below and flow arbitrarily, or drip on other equipment and facilities below, thereby polluting or mixing other chemical raw materials and causing danger. When the liquid raw materials flowing into the anti-leakage groove 1 reach a certain amount, they will flow in the anti-leakage groove 1. On the one hand, the flowing raw materials will be collected into the infusion pipe 7 through the collecting funnels 8, and continue to pass through the drainage bends on both sides. The liquid in the pipe 9 reaches the collecting pipe 10 and is discharged uniformly. On the other hand, it flows through the flow sensor 13, triggering the alarm mechanism. Under normal conditions, the pipeline valves and related processing equipment will be closed accordingly, and the specially matched foam nozzles 17 located above the feed pipeline 2 on the device will start to run, and the foam liquid in the spray water pipe 14 will be sprayed toward the feed pipeline 2, so that the foam covers and fuses the leaked liquid chemical raw materials to prevent further dangerous spread such as volatilization and fire. The foam liquid mixed with the liquid chemical raw materials in the leak-proof plate also flows into the collecting pipe 10 for discharge along the discharge system pipeline, and will not cause significant pollution to the environment.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
