Description

Technical Field

[0001] The utility model relates to the field of safety protection devices for leakage of hazardous chemical materials, in particular to a safety protection device for leakage of hazardous chemical materials. Background Art

[0002] Chemical production or experiments produce new substances through specific chemical reactions between different substances, thereby obtaining the material raw materials needed for the product. Some chemical materials are not active enough under normal conditions and are relatively harmless, but when the environment changes, they may become relatively active and have dangerous properties such as flammable, explosive, toxic, and highly corrosive.

[0003] During the production or experimental process, it is a common process to heat the materials to make them reactive. Some liquid raw materials will produce toxic steam and gas in a heated environment, such as methane and iodine vapor, which threaten the health and safety of personnel. These toxic gases will slowly overflow through the inlets and outlets, equipment connections, or some gaps in the equipment. In the production plant or laboratory, the ventilation effect may not be good enough, or the toxic gas accumulated in the external environment may be relatively slow and difficult to detect in time. Once a threat to personal safety occurs, irreparable losses may occur. Therefore, a safety protection device for the leakage of hazardous chemical materials is needed. Utility Model Content

[0004] 1. Technical Problems Solved

The liquid discharge pipe is connected with a No. 1 solenoid valve. When the No. 1 solenoid valve is opened, the materials in the heating tank can be discharged through the liquid discharge pipe. The exhaust pipe is connected with a fan. Through the exhaust pipe, the toxic steam generated by the material in the heating tank after heating is forcefully extracted into the rewarming tank for temporary storage to prevent the toxic gas from slowly overflowing from other vents and gaps, causing leakage into the external working environment and creating danger.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] Combined with Figure 1 , Attachment Figure 2 In order to solve the above technical problems, the technical solution provided by the utility model is: a safety protection device for leakage of hazardous chemical materials, including a heating tank 1, which is a place for heating chemical liquid materials. One end of the heating tank 1 is connected with a liquid inlet pipe 2, and the liquid inlet pipe 2 is connected with a No. 1 water pump 3, which is used to transport the chemical materials that need to be heated and treated into the heating tank 1 through the liquid inlet pipe 2. The bottom end of the heating tank 1 is connected with a discharge pipe 8 that matches the liquid inlet pipe 2, and the discharge pipe 8 is connected with a No. 1 solenoid valve 9. Opening the No. 1 solenoid valve 9 can allow the materials in the heating tank 1 to be discharged through the discharge pipe 8. One side of the heating tank 1 is connected with a heating box 11, which is a device and facility that continuously provides a heat source for the heating tank 1.

[0025] Embodiment 2

[0026] Combined with Figure 1 , Attachment Figure 3 The heating tank 1 is rotatably connected with a transmission shaft 4 for driving the stirring blades 5 to rotate. The outer side of the transmission shaft 4 is connected with a plurality of stirring blades 5 that cooperate with the heating tank 1. When rotating in the heating tank 1, the material liquid in the tank is beaten and driven to roll and rotate, so that the material liquid can contact with the thin-walled curved pipe 10 carrying hot water more fully, so that the material liquid can be heated more effectively and evenly. The heating tank 1 is connected with a support frame 7 that cooperates with the transmission shaft 4 for auxiliary support of the rotation of the transmission shaft 4. The heating tank 1 is connected with a drive motor 6 that cooperates with the transmission shaft 4 at one end away from the liquid inlet pipe 2 to provide power for the rotation of the transmission shaft 4.

[0027] By driving the motor 6, the transmission shaft 4 and the stirring blades 5 carried thereon are driven to rotate in the heating tank 1, so that the chemical liquid material is heated more quickly and evenly.

[0028] Embodiment 3

[0029] Combined with Figure 1-5 The heating tank 1 is provided with a thin-walled curved pipe 10 located outside the stirring blade 5. The thin-walled curved pipe 10 is spirally shaped and directly contacts the chemical liquid material in the heating tank 1. The diameter of the thin-walled curved pipe 10 is smaller than the water pipe 12 and the return pipe 13. The water pipe 12 is connected to one end of the thin-walled curved pipe 10 and one side of the bottom of the heating box 11. The water pipe 12 is used for the water to flow from the heating box 11 into the thin-walled curved pipe 10. The thin-walled curved pipe 10 is away from the water pipe 12 and is connected to the supply box 11. A return pipe 13 is commonly connected to one side of the top of the heat box 11, which is a channel for water to flow from the thin-walled curved pipe 10 back to the heating box 11. The return pipe 13 is connected to a second water pump 14, which is used to pump the water in the thin-walled curved pipe 10 back to the heating box 11 through the return pipe 13 for heat recovery and re-circulation. Both ends of the thin-walled curved pipe 10 are commonly connected to the water supply pipe 12 and the return pipe 13 respectively, and a reducer 23 is commonly connected to the water pipes 12 and the return pipe 13 for connecting water pipes of different diameters at both ends.

[0030] The heating box 11 is connected with a plurality of partitions 15, through which the space in the heating box 11 is separated into a swirling water flow channel. The heating box 11 is connected with a plurality of electric heating columns 16, which are arranged in multiple layers and groups and are respectively located at each layer separated by the partitions 15, so as to increase the contact between the water flow and the electric heating elements, thereby generating high-temperature water more quickly and circulating it in real time to supply it to the heating tank 1 for use.

[0031] By directly setting the thin-walled curved pipe 10 in the heating tank 1, it is directly and fully in contact with the stirred liquid, which increases the area of ​​heat transfer between the hot water in the pipe and the liquid in the tank, thereby making the heating effect more obvious. Through the continuous operation of the heating box 11 and the No. 2 water pump 14, hot water can continuously circulate back and forth in the heating system, thereby realizing real-time heat supply.

[0032] Embodiment 4

[0033] Combined with Figure 1 , Attachment Figure 3 A rewarming tank 19 is connected to one side of the heating tank 1 for temporarily storing toxic vapor substances extracted from the top of the heating tank 1 by an exhaust pipe, and providing a place for cooling and warming them up until they are restored to a liquid state. An exhaust pipe 17 is commonly connected between the heating tank 1 and the top of the rewarming tank 19, and a fan 18 is connected to the exhaust pipe 17. The toxic vapor generated by the material in the heating tank 1 after heating is forcefully extracted into the rewarming tank 19 for temporary storage through the exhaust pipe 17 to prevent the toxic gas from slowly overflowing from other vents and gaps, causing leakage to the external working environment and causing danger. A plurality of temperature conducting plates 20 are connected to the wall of the rewarming tank 19, and the two ends of the temperature conducting plates 20 extend to the inside and outside of the rewarming tank 19 respectively. A waste pipe 21 is connected to the bottom of the rewarming tank 19, and a No. 2 solenoid valve 22 is connected to the waste pipe 21. When opened, the waste liquid cooled back to room temperature in the rewarming tank 19 can be discharged through the waste pipe 21.

[0034] Through the action of the exhaust pipe 17 and the fan 18 it carries, the toxic vapors generated by the chemical liquid materials in the heating tank 1 when heated to a certain temperature are concentrated and collected in the rewarming tank 19, thereby avoiding or reducing the possibility of these toxic vapors leaking from the feed pipe mouth and other places to the external environment. The rewarming tank 19 is provided with a heat-conducting material plate connected to the external environment. By enhancing the heat exchange between the toxic and dangerous substances in the gas-liquid mixed state in the tank and the outside air, the steam in the tank is gradually restored to a liquid state and then processed centrally.

[0035] When the utility model is implemented in detail, the device can adjust the size of the whole or corresponding components and mechanisms according to the objective needs and limitations of the use site, such as in a laboratory or a production workshop; when the device is running, the liquid chemical material enters the heating tank 1 from the liquid inlet pipe 2, and the driving motor 6 at one end provides power, and the transmission shaft 4 in the heating tank 1 drives the stirring blade 5 to stir the material in the tank. At the same time, the thin-walled curved pipe 10 in the tank is filled with hot water, and heat is transferred through the contact between the pipe wall and the material, so that the material in the tank is heated, and the hot water in the pipe is flowing. Under the action of the No. 2 water pump 14 in the heating system, the hot water flows out from one end of the thin-walled curved pipe 10, and returns to the heating box 11 through the reflux pipe 13. The hot water enters from the top side of the box body, and falls layer by layer from top to bottom in the box with the action of gravity. In the process of falling, it contacts with multiple electric heating columns 16, so that its own temperature gradually increases, and is heated. The reheated hot water comes to the bottom of the box body, and returns to the heating tank 1 again from the water pipe 12 connected between the heating box 11 and the thin-walled curved pipe 10 to heat the material in the tank, and the No. 2 water pump 14 circulates continuously. As the material is heated to above a certain temperature, toxic steam will be continuously generated. At this time, the exhaust pipe connected between the heating tank 1 and the top of the reheating tank 19 is running with the fan 18, and the toxic steam generated in the heating tank 1 is continuously extracted and sent to the reheating tank 19 for temporary storage. Since it is away from the high temperature environment, the steam sent to the reheating tank 19 will slowly liquefy. The heat dissipation and reheating mechanism arranged on the reheating tank 19 includes multiple temperature conduction plates 20, which can accelerate the liquefaction process of the toxic steam. When the heating process is completed, the toxic steam has also returned to the liquid state. Open the No. 1 solenoid valve 9 and the No. 2 solenoid valve 22 respectively, and discharge the liquid in the two tanks to the corresponding collection device through the drain pipe 8 and the waste pipe 21.

[0036] 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.
