Description

Technical Field

[0001] The present invention relates to the field of storage of hazardous chemicals, and particularly to a storage device for hazardous chemicals with a protection function. Background Art

[0002] Before the transportation of hazardous chemicals, the hazardous chemicals need to be stored in a hazardous chemical storage container for transportation. During the transportation of hazardous chemicals, the hazardous chemical storage container may leak. The existing Chinese patent CN116631159A discloses a hazardous chemical leakage protection and alarm device. After the chemical leakage is detected, the airbag is inflated to push the protection ring to move upward, so as to perform a protection and sealing treatment on the chemicals on the placement table. The closed airbag and the extended airbag start to be inflated. The closed airbag is inflated and becomes a semi-circular plate to seal the upper end of the protection tube, preventing the chemicals from spreading into the air, thus achieving a better protection effect. Moreover, according to the leakage situation of the chemicals, the leaked chemicals can be sealed, playing a better protective role.

[0003] However, although the above patent performs emergency treatment on the hazardous chemical storage container after the leakage occurs, it takes time to detect and implement the emergency treatment of the chemical leakage. When the alarm processing device detects harmful gases, the harmful gases have already spread to the outside, affecting the surrounding environment. Summary of the Invention

[0008] Further, atomizing nozzles are provided on all the water spray pipes.

[0009] Further, it further includes a check valve; a check valve is communicated on the shielding cover.

[0010] Further, it further includes a fan II; a fan II is installed inside the shielding cover.

[0011] Further, it further includes an adsorption tube and a signal lamp; a vacuum generator is provided inside the installation ring; six adsorption tubes are arranged on the folding airbag, air holes are opened on the adsorption tubes, the adsorption tubes and the connecting pipes are arranged in a staggered manner, and the adsorption tubes are connected to the vacuum generator inside the installation ring; the six gas detectors inside the installation ring are respectively located between adjacent adsorption tubes; six signal lamps are provided on the installation ring, and the signal lamps are opposite to the gas detectors.

[0012] Further, it further includes an electric push rod and an extrusion strip; several electric push rods are installed on the bearing frame; the telescopic parts of all the electric push rods are fixedly connected with the extrusion strip.

[0013] Further, the extrusion strip is made of rubber material.

[0014] Further, a rubber layer is provided at the bottom of the bearing frame.

[0015] Advantages of the present invention: When a leakage occurs in a hazardous chemical storage container and is detected by the gas detector inside the mounting ring, the present invention restricts the harmful gas generated by the leakage through the folding airbag, the mounting ring and the shielding cover, avoiding the diffusion of the harmful gas to the outside and affecting the surrounding environment.

[0016] According to different chemicals stored in the storage container, the present invention realizes different treatments for different chemicals by setting a purification device or a collector at the exhaust port, connecting an external processing agent delivery device or a collector to the valve, and adding a water spray pipe, a micro pump and a connecting pipe. That is, for chemicals that cannot be recycled, the external processing agent delivery device and the valve are used to deliver the processing agent into the carrying frame, and the processing agent is atomized and sprayed out through the water spray pipe, the micro pump and the connecting pipe to react with the harmful gas volatilized from the non-recyclable chemicals, reducing the processing burden of the purification device. For recyclable chemicals, the fan I discharges the harmful gas volatilized by them into the collector for collection. At this time, the valve is connected to the collector, and the recyclable chemicals are discharged into the collector through the valve, realizing the rapid collection of the leaked and recyclable chemicals.

[0017] By adding a one-way valve to the shielding cover, when the fan I extracts the gas in the folding airbag, the outside air can enter the folding airbag through the one-way valve, so that a certain gap can be maintained between the folding airbag and the hazardous chemical storage container, which is conducive to the flow of harmful gas in the folding airbag.

[0018] By rotating the fan II, the outside air entering the folding airbag from the one-way valve is increased, and the flow rate of the atomized processing agent can also be increased as the fan II rotates, so that the atomized processing agent can cover the hazardous chemical storage container faster, which is conducive to the treatment of hazardous chemicals.

[0019] By starting the vacuum generator inside the mounting ring to provide adsorption force for the adsorption tube, the adsorption tube is attached to the hazardous chemical storage container. After the adsorption tube is attached to the hazardous chemical storage container, the gap between the hazardous chemical storage container and the folding airbag is divided into six channels by the adsorption tube, and a signal lamp corresponds to the upper part of each of the six channels respectively, and six gas detectors are respectively located between adjacent adsorption tubes. The gas in the six channels is detected by the gas detectors. If harmful gas is detected in the channel, the signal lamp above the corresponding channel will light up, facilitating the rapid determination of the leakage point on the hazardous chemical storage container by the operator.

[0024] The bearing frame 1 is made of a transparent material, which is convenient for observing the leakage of the treatment agent and liquid hazardous chemicals.

[0025] The folding airbag 3 and the mounting ring 4 are detachably connected, which avoids the folding airbag 3 from affecting the temporary treatment of the leakage of the hazardous chemical storage container by humans, and at the same time facilitates the extraction of the leaked gas by the fan I 6.

[0026] Atomizing nozzles are provided on all the spray pipes 9, which is conducive to the reaction between the treatment agent and the leaked harmful gas.

[0027] It also includes a one-way valve 101; the one-way valve 101 is connected to the shielding cover 5, which is conducive to the flow of harmful gas in the folding airbag 3.

[0028] It also includes a fan II 102; the fan II 102 is installed in the shielding cover 5 and is used to increase the outside air entering the folding airbag 3 from the one-way valve 101.

[0029] It also includes an adsorption tube 11 and a signal lamp 12; a vacuum generator is provided in the mounting ring 4; six adsorption tubes 11 are arranged on the inner wall of the folding airbag 3, air holes are formed on the adsorption tubes 11, the adsorption tubes 11 and the connecting tube 10 are arranged in a staggered manner, and the adsorption tubes 11 are connected to the vacuum generator in the mounting ring 4; the six gas detectors in the mounting ring 4 are respectively located between adjacent adsorption tubes 11; six signal lamps 12 are provided on the mounting ring 4, and the signal lamps 12 are opposite to the gas detectors.

[0030] As Figure 1 shown, the left 1 of the present invention is in the retracted state, and the right 1 of the present invention is in the use state. The position where the fan I 6 is located in the present invention is the exhaust port.

[0031] Initially, the present invention is in Figure 1 the retracted state shown in the right 1 in the figure. Before putting the dangerous chemical storage container into the present invention, first open the shielding cover 5 on the mounting ring 4, and then manually put the dangerous chemical storage container into the bearing frame 1. The dangerous chemical storage container is supported by the supporting plate 2. The dangerous chemical storage container is located inside the folding airbag 3, and there is a certain gap between the folding airbag 3 and the dangerous chemical storage container. Then manually pull up the mounting ring 4, and the folding airbag 3 and the shielding cover 5 move upward accordingly. After the mounting ring 4 and the shielding cover 5 are higher than the dangerous chemical storage container, re-fasten the shielding cover 5 on the mounting ring 4, and at the same time fix the mounting ring 4 on the dangerous chemical storage container through a screw, so that the present invention changes from the retracted state to the use state, and the dangerous chemical storage container is covered and protected. Different from the prior art, when the gas detector in the mounting ring 4 detects that the dangerous chemical storage container leaks, the present invention can limit the harmful gas generated by the leakage through the folding airbag 3, the mounting ring 4 and the shielding cover 5, and avoid the harmful gas from diffusing to the outside and affecting the surrounding environment.

[0032] When it is necessary to transfer the dangerous chemical storage container, manually connect the hook 7 with the hoisting device, and then control the hoisting device to lift the present invention, and transfer the present invention and the dangerous chemical storage container to a container or a transport vehicle.

[0033] The chemicals stored in the hazardous chemical storage container are divided into two types. One is the recyclable chemicals, and the other is the non-recyclable chemicals. When storing non-recyclable chemicals, the purification device is connected to the air outlet. When the gas detector in the mounting ring 4 detects a leak of non-recyclable chemicals, the gas detector activates the fan I 6 to extract the gas in the carrier frame 1 and the folding airbag 3. The extracted gas flows from the folding airbag 3 to the bottom of the carrier frame 1, then passes through the through slot 21 and flows to the bottom of the carrier frame 1. The gas at the bottom of the carrier frame 1 is drawn to flow from the through hole 22 towards the fan I 6, and then the gas is pushed by the fan I 6 to the purification device for purification treatment. To reduce the treatment burden of the purification device on non-recyclable chemicals, a valve 8 is added to the carrier frame 1, a micro pump is added to the mounting ring 4, a water spray pipe 9 is added to the shielding cover 5, the water spray pipe 9 is connected to the outlet of the micro pump in the mounting ring 4, a connecting pipe 10 is added to the inner wall of the folding airbag 3, the connecting pipe 10 is connected to the inlet of the micro pump in the mounting ring 4, and the bottom end of the connecting pipe 10 passes through the through slot 21 and contacts the inner bottom surface of the carrier frame 1; Before using the present invention, the valve 8 is connected to an external treatment agent delivery device through an external pipeline, and then the valve 8 is opened. The treatment agent is transported through the valve 8 into the carrier frame 1 by the external treatment agent delivery device. It should be noted that the carrier frame 1 is made of a transparent material, and the operator can directly determine the water level of the treatment agent. The water level height of the treatment agent is lower than the support plate 2, and the bottom end of the connecting pipe 10 is located in the treatment agent. After the treatment agent transportation is completed, the valve 8 is closed. After a leak of non-recyclable chemicals is detected by the gas detector in the mounting ring 4, the gas detector activates the micro pump and the fan I 6 in the mounting ring 4. The micro pump in the mounting ring 4 extracts the treatment agent in the carrier frame 1 through the connecting pipe 10, and the micro pump transports the extracted treatment agent into the water spray pipe 9 on the shielding cover 5. The treatment agent is sprayed out from the atomizing nozzles on the water spray pipe 9 in an atomized manner. The atomized treatment agent covers the hazardous chemical storage container, and the atomized treatment agent reacts with the harmful gases leaking around the hazardous chemical storage container to neutralize the harmful gases and reduce the burden on the purification device.

[0034] When the stored non-recyclable chemicals are in a liquid state, the liquid non-recyclable chemicals directly flow into the treatment agent for dilution. At the same time, the fan I 6 discharges the harmful gases generated by the liquid non-recyclable chemicals into the purification device for purification treatment. For the non-recyclable chemicals diluted by the treatment agent, the operator can subsequently open the valve 8 to transfer the treatment agent and the diluted non-recyclable chemicals.

[0035] When storing recyclable chemicals, a gas collector is installed at the exhaust port. When the gas detector in the mounting ring 4 detects a leak of recyclable chemicals, the gas detector activates the fan I 6 to extract the gas in the carrying frame 1 and the folding airbag 3. The extracted gas flows from the folding airbag 3 towards the bottom of the carrying frame 1. The extracted gas passes through the through slot 21 and flows to the bottom of the carrying frame 1. The gas at the bottom of the carrying frame 1 is drawn to flow from the through hole 22 towards the fan I 6, and then the gas is pushed by the fan I 6 into the gas collector for collection, avoiding waste. If the stored recyclable chemical is in liquid form, a collector is connected to the valve 8, and at this time the valve 8 is in the open state. When the liquid recyclable chemical leaks, it can be directly discharged into the collector through the valve 8, avoiding the situation that the fan I 6 cannot handle the liquid recyclable chemical.

[0036] Considering that after the gas in the folding airbag 3 is extracted, due to the limited air in the folding airbag 3, as the gas in the folding airbag 3 is continuously sucked, the gap between the folding airbag 3 and the hazardous chemical storage container gradually decreases, which is not conducive to the flow of harmful gas in the folding airbag 3. By adding a one-way valve 101 to the shielding cover 5, when the fan I 6 extracts the gas in the folding airbag 3, the outside air can enter the folding airbag 3 through the one-way valve 101, so that a certain gap can be maintained between the folding airbag 3 and the hazardous chemical storage container, which is conducive to the flow of harmful gas in the folding airbag 3.

[0037] By adding a fan II 102 in the shielding cover 5, when the fan I 6 is started, the fan II 102 is started synchronously. By the rotation of the fan II 102, the outside air entering the folding airbag 3 is increased, and at the same time, the flow rate of the atomized treatment agent can be increased as the fan II 102 rotates, so that the atomized treatment agent can cover the hazardous chemical storage container faster, which is conducive to the treatment of hazardous chemicals.

[0038] After a leakage of hazardous chemicals occurs, it is necessary for workers to promptly carry out temporary treatment on the leakage point of the hazardous chemical storage container to prevent continuous leakage of hazardous chemicals. However, it is not easy for workers to quickly determine the leakage point. Therefore, by adding an adsorption tube 11 to the inner wall of the folding airbag 3, with air holes opened on the adsorption tube 11, and the adsorption tube 11 and the connecting tube 10 being staggered. The adsorption tube 11 is connected to a vacuum generator inside the mounting ring 4. Six signal lights 12 are added to the mounting ring 4. When the gas detector detects a leakage, first control the fan I 6 to extract the gas inside the folding airbag 3. As the air inside the folding airbag 3 decreases, the gap between the folding airbag 3 and the hazardous chemical storage container gradually becomes smaller, and the adsorption tube 11 gradually approaches the hazardous chemical storage container. Then start the vacuum generator inside the mounting ring 4 to provide an adsorption force for the adsorption tube 11, so that the adsorption tube 11 fits on the hazardous chemical storage container. After the adsorption tube 11 fits on the hazardous chemical storage container, the gap between the hazardous chemical storage container and the folding airbag 3 is divided into six channels by the adsorption tube 11. It should be noted that before the gap between the hazardous chemical storage container and the folding airbag 3 is divided into six channels, there is not enough pressure inside the folding airbag 3, the one-way valve 101 will not open, and the fan II 102 will not rotate, to avoid affecting the formation of the channels. And directly above the six channels, each corresponds to a signal light 12, and six gas detectors are respectively located between adjacent adsorption tubes 11. As the fan I 6 extracts the gas inside the folding airbag 3, the harmful gases originally filling the gap between the hazardous chemical storage container and the folding airbag 3 all flow towards the purification device or the collector. At this time, start the gas detector again to detect the harmful gases. It should be noted that when starting the gas detector again to detect the harmful gases, the fan I 6 and the fan II 102 will stop rotating. The gas detector detects the gas in the six channels. If harmful gases are detected in a channel, the signal light 12 directly above the corresponding channel will light up, facilitating workers to quickly determine the leakage point on the hazardous chemical storage container. It should be noted that when workers carry out temporary treatment on the leakage point of the hazardous chemical storage container, loosen the screw on the mounting ring 4 to separate the mounting ring 4 from the hazardous chemical storage container. Then manually open the shielding cover 5 and lower the mounting ring 4 so that the folding airbag 3 no longer blocks the hazardous chemical storage container. At this time, workers carry out temporary treatment on the leakage point of the hazardous chemical storage container, and the fan I 6 continuously operates to extract the leaked gas, and the leaked gas will not spread to the outside. It should be noted that a high-power fan I 6 can be used to ensure the extraction effect of the fan I 6 on the leaked gas.

[0039] When workers carry out temporary treatment on the leakage point of the hazardous chemical storage container, the folding airbag 3 can be removed from the mounting ring 4 to avoid the folding airbag 3 affecting the temporary treatment of the leakage point of the hazardous chemical storage container by workers, and at the same time facilitating the fan I 6 to extract the leaked gas.

[0040] Example 2 Based on Example 1, as Figure 3 and Figure 4 shown, it further includes an electric push rod 110 and an extrusion strip 111; four electric push rods 110 are installed on the bearing frame 1; the telescopic parts of all the electric push rods 110 are fixedly connected with the extrusion strip 111.

[0041] The extrusion strip 111 is made of rubber material to enhance the friction between the extrusion strip 111 and the folding airbag 3, avoid slipping, and affect the fixation of the dangerous chemical storage container.

[0042] A rubber layer is provided at the bottom of the bearing frame 1 to improve the stability of the present invention.

[0043] During the transfer process of the present invention and the dangerous chemical storage container, since there is no fixation between the present invention and the dangerous chemical storage container, when the present invention and the dangerous chemical storage container are lifted by a hoisting device, the dangerous chemical storage container shakes inside the present invention, affecting the stability of hoisting and prone to safety accidents. By adding an electric push rod 110 to the bearing frame 1 and adding an extrusion strip 111 to the telescopic part of the electric push rod 110, before the present invention and the dangerous chemical storage container are lifted by a hoisting device, control the electric push rod 110 to push out, so that the extrusion strip 111 presses on the folding airbag 3 to fix the dangerous chemical storage container in the present invention and avoid the dangerous chemical storage container shaking inside the present invention and affecting the stability of hoisting.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
