Description

Technical Field

[0001] This utility model belongs to the field of textile testing technology, specifically an oxygen bomb tank protection device. Background Technology

[0002] The detection of halogen (chlorine, bromine, fluorine, iodine) content in textiles is an important indicator for assessing their environmental friendliness and safety, especially under regulations (such as REACH and GB standards) that restrict hazardous substances (e.g., halogenated flame retardants, PVC plasticizers). Current technologies commonly use a combination of combustion oxygen bomb method and ion chromatography to detect halogen content in textiles. The textile is burned in a high-pressure oxygen bomb, releasing halogens which are absorbed by an absorbent solution and then quantitatively analyzed by ion chromatography. Before combustion, a large amount of high-pressure oxygen needs to be introduced into the bomb canister through a one-way valve at the top. The combustion process generates significant heat, posing a risk of explosion during ignition. Cooling takes a considerable amount of time, and exhaust gas release requires personnel to use a metal rod to press the one-way valve. This rough release poses hazards to personnel and pollutes the environment, and improvements are needed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oxygen bomb tank protection device.

[0004] The present invention adopts the following technical solution:

[0005] An oxygen bomb canister protection device includes an explosion-proof mechanism, a cooling mechanism, and a tail gas treatment mechanism. The explosion-proof mechanism includes an upper protective cover, a lower protective cover, and a locking assembly. The upper and lower protective covers are positioned opposite each other outside the oxygen bomb canister, respectively opposite the oxygen bomb canister's top cover and main body. The locking assembly is positioned between the upper and lower protective covers to lock them together. The cooling mechanism is positioned outside the lower protective cover. The tail gas treatment mechanism includes a venting assembly, an exhaust pipe, and a tail gas collection assembly. The venting assembly includes a sliding groove, a venting button, and a return spring. The sliding groove is formed on the top of the upper protective cover. The venting button is movable up and down in the sliding groove. An extension rod is provided at the bottom of the venting button, opposite to the oxygen bomb canister's air inlet. The extension rod extends into the oxygen bomb canister's air inlet as the venting button moves downward. The return spring is connected between the sliding groove and the venting button, giving the venting button a tendency to always move upward. The tail gas collection assembly is connected to the upper protective cover to collect and treat the discharged tail gas.

[0006] Preferably, both the upper and lower ends of the sliding groove are provided with inwardly recessed limiting rings, the diameter of the vent button is adapted to the inner diameter of the limiting ring, and a sealing ring is formed by protruding outward on the outer side of the vent button. The outer side of the sealing ring fits and seals against the inner side of the sliding groove, and the reset spring is connected between the top surface of the lower limiting ring and the bottom surface of the sealing ring.

[0007] Preferably, the cooling mechanism includes a base, a circulating hose, a circulating water pump, and a radiator. The base has a cavity formed inside for the lower protective cover to be placed. The circulating hose spirally wraps around the inner wall of the cavity and can contact the lower protective cover. Its upper and lower ends extend outward to the base and are interconnected. The circulating water pump and the radiator are connected to the circulating hose in sequence.

[0008] Preferably, the upper protective cover includes an upper cover body adapted to the shape of the upper half of the oxygen bomb canister and an upper energy-absorbing ceramic body attached to the inner side of the upper cover body, and the lower protective cover includes a lower cover body adapted to the shape of the lower half of the oxygen bomb tube and a lower energy-absorbing ceramic body attached to the inner side of the lower cover body.

[0009] Preferably, the top of the upper cover extends upward to form a protrusion, the venting component is disposed on the top surface of the protrusion, and a clearance space higher than the top surface of the oxygen bomb tank is formed inside the protrusion. The exhaust gas collection component includes an exhaust pipe, an exhaust gas treatment chamber, and an exhaust pipe. The exhaust pipe is disposed on the side of the protrusion and communicates with the clearance space. Several exhaust gas treatment chambers are provided and connected end to end. The top of the previous exhaust gas treatment chamber communicates with the bottom of the next exhaust gas treatment chamber. The exhaust pipe is disposed at the end of the exhaust gas treatment chamber and communicates with the outside.

[0010] Preferably, the bottom surface of the upper cover extends outward to form an upper outer edge, and the top surface of the lower cover extends outward to form a lower outer edge. The locking assembly includes an upper positioning hole, a lower positioning hole, a mounting bolt, and a wing nut. Several upper positioning holes are provided and are uniformly formed along the circumferential direction on the upper outer edge. The lower positioning holes are formed on the lower outer edge and correspond one-to-one with the upper positioning holes. The mounting bolt passes through the lower positioning hole and the upper positioning hole sequentially from bottom to top. The wing nut cooperates with the mounting bolt to fix the upper and lower protective covers.

[0011] Preferably, the upper and lower energy-absorbing ceramic bodies are made of alumina ceramic.

[0012] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are: the cooling mechanism is used to cool the heat released during the combustion of the oxygen bomb canister, and the explosion-proof mechanism covers the oxygen bomb canister inside, which can protect the safety of external equipment and experimental personnel in the event of a canister explosion. At the same time, the experimental personnel can press the vent button set on the upper protective cover to move the extension rod downward to press the one-way valve on the oxygen bomb canister to vent the gas. The exhaust gas directly enters the exhaust gas collection assembly for treatment, and the experimental personnel will not come into contact with the exhaust gas, thus improving safety.

[0013] The vent button and the sliding groove are sealed by a sealing ring and a limit ring to prevent exhaust gas from being discharged from the connection between the two during venting.

[0014] The upper and lower energy-absorbing ceramic bodies installed inside the upper and lower covers can absorb the impact force in the event of a can explosion, preventing damage to the upper and lower covers. Only the ceramic bodies need to be replaced, reducing costs. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below through specific embodiments.

[0022] Reference Figures 1 to 5 As shown, an oxygen bomb tank protection device includes an explosion-proof mechanism 1, a cooling mechanism 2, and an exhaust gas treatment mechanism 3.

[0023] The explosion-proof mechanism 1 includes an upper protective cover 11, a lower protective cover 12, and a locking assembly 13. The upper protective cover 11 and the lower protective cover 12 are arranged opposite each other on the outside of the oxygen bomb canister, respectively opposite to the oxygen bomb canister top cover and the oxygen bomb canister body. The upper protective cover 11 has a clearance hole 111 formed on it, into which the ignition wire of the oxygen bomb canister ignition device can be inserted. A rubber sealing ring 122 is also provided at the clearance hole 111 to seal the gap between the clearance hole 111 and the ignition wire to prevent leakage during exhaust. The locking assembly 13 is arranged between the upper protective cover 11 and the lower protective cover 12 to lock the two together. The upper protective cover 11 includes an upper cover body 113 adapted to the shape of the upper half of the oxygen bomb canister and an upper energy-absorbing ceramic body 114 fitted inside the upper cover body 113. The lower protective cover 12 includes a lower cover body 121 adapted to the shape of the lower half of the oxygen bomb tube and a lower energy-absorbing ceramic body 122 fitted inside the lower cover body 121. The upper energy-absorbing ceramic body 114 and the lower energy-absorbing ceramic body 122 are made of alumina ceramic. Alumina ceramic can absorb the impact force in the event of a canister explosion, preventing damage to the upper cover body 113 and the lower cover body 121. Only the ceramic body needs to be replaced, reducing costs. Specifically, the top of the upper cover body 113 extends upward to form a protrusion 115, and the protrusion 115 has a clearance space higher than the top surface of the oxygen bomb canister. Furthermore, the bottom surface of the upper cover 113 extends outward to form an upper outer edge 116, and the top surface of the lower cover 121 extends outward to form a lower outer edge 123. The locking assembly 13 includes an upper positioning hole 131, a lower positioning hole 132, a mounting bolt 133, and a wing nut 134. Several upper positioning holes 131 are evenly formed along the circumference of the upper outer edge 116. The lower positioning holes 132 are formed on the lower outer edge 123 and correspond one-to-one with the upper positioning holes 131. The mounting bolt 133 passes through the lower positioning hole 132 and the upper positioning hole 131 sequentially from bottom to top. The wing nut 134 cooperates with the mounting bolt 133 to fix the upper protective cover 11 and the lower protective cover 12. The wing nut 134 allows experimental personnel to quickly lock the cover without tools, improving work efficiency.

[0024] The cooling mechanism 2 is located outside the lower protective cover 12. The cooling mechanism 2 includes a base 21, a circulating hose 22, a circulating water pump 23, and a radiator 24. The base 21 has a cavity formed inside for the lower cover 121 to be placed. The circulating hose 22 spirally wraps around the inner wall of the cavity and can contact the lower cover 121. Its upper and lower ends extend outwards to the base 21 and are interconnected. The circulating water pump 23 and the radiator 24 are sequentially connected to the circulating hose 22. The cooling mechanism 2 is a common circulating water cooling device in the prior art, which can be directly and clearly obtained by those skilled in the art, and is not the focus of this application. Therefore, its structure and selection will not be further described here.

[0025] The exhaust gas treatment mechanism 3 includes an exhaust gas venting component 31 and an exhaust gas collection component 32. The exhaust gas venting component 31 is disposed on the top surface of the protrusion 115 and includes a sliding groove 311, an exhaust gas venting button 312, and a return spring 313. The sliding groove 311 is formed on the top of the upper protective cover 11. The exhaust gas venting button 312 is movably disposed in the sliding groove 311. An extension rod 314 is disposed at the bottom of the exhaust gas venting button 312, which is opposite to the oxygen bomb canister inlet. The extension rod 314 can extend into the oxygen bomb canister inlet as the exhaust gas venting button 312 moves downward. The return spring 313 is connected between the sliding groove 311 and the exhaust gas venting button 312, so that the exhaust gas venting button 312 always has an upward tendency. The exhaust gas collection assembly 32 is connected to the upper protective cover 11 to collect and treat the exhaust gas. The exhaust gas collection assembly 32 includes an outlet pipe 321, an exhaust gas treatment chamber 322, and an exhaust pipe 323. The outlet pipe 321 is located on the side of the protrusion 115 and communicates with the clearance space. Several exhaust gas treatment chambers 322 are provided and connected end to end. The top of the previous exhaust gas treatment chamber 322 is connected to the bottom of the next exhaust gas treatment chamber 322. The exhaust gas treatment chamber 322 is filled with a solution that can react with the exhaust gas. The outlet pipe 321 is located at the end of the exhaust gas treatment chamber 322 and communicates with the outside. Specifically, both the upper and lower ends of the sliding groove 311 are provided with inwardly recessed limiting rings 315. The diameter of the vent button 312 is adapted to the inner diameter of the limiting ring 315. A sealing ring 316 is formed protruding outward from the outer side of the vent button 312. The outer side of the sealing ring 316 fits and seals against the inner side of the sliding groove 311. The reset spring 313 is connected between the top surface of the lower limiting ring 315 and the bottom surface of the sealing ring 316. The vent button 312 and the sliding groove 311 are sealed by the sealing ring 316 and the limiting ring 315 to prevent exhaust gas from being discharged from the connection between the two during exhaust.

[0026] In use, the sample to be burned is placed into the oxygen bomb canister and assembled. Sufficient high-pressure oxygen is then introduced through the one-way valve on the top of the canister. After connecting the ignition device through the clearance hole 111, the upper protective cover 11 and the lower protective cover 12 are installed on the outside of the oxygen bomb canister and locked using the locking assembly 13. Finally, the lower protective cover 12 is placed in the base 21 of the cooling mechanism 2 to start the device. The cooling mechanism 2 is used to cool the heat released during combustion of the oxygen bomb canister, facilitating quick disassembly of the canister for result measurement after the experiment. An explosion-proof mechanism 1 encloses the oxygen bomb canister, protecting the external cooling device and the safety of the experimenters in the event of an explosion. The experimenters can press the vent button 312 on the upper protective cover 11 to move the extension rod 314 downwards, thereby pressing the one-way valve on the oxygen bomb canister to release the exhaust gas. The exhaust gas directly enters the exhaust gas collection assembly 32 for treatment, preventing the experimenters from contacting the exhaust gas and improving safety, making it highly practical.

All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
