Description

Technical Field

[0001] This utility model relates to the field of chemical instrumentation technology, specifically to a high-safety-performance explosion-proof structure for chemical instruments. Background Technology

[0002] Chemical instrumentation plays a vital role in the chemical industry. These instruments are indispensable tools, not merely simple measuring devices, but key factors ensuring smooth chemical production processes, improving efficiency, and enhancing product quality. Firstly, chemical instrumentation monitors and controls various critical parameters such as temperature, pressure, flow rate, and liquid level. These parameters directly impact the rate of chemical reactions, conversion rates, and the quality of the final product. By monitoring these parameters in real time, chemical instrumentation ensures the production process remains optimal, preventing production accidents and product quality issues caused by parameter fluctuations. Secondly, chemical instrumentation possesses high precision and stability. In chemical production, even minute parameter changes can significantly affect results. Therefore, chemical instrumentation requires high-precision measurement capabilities and stable performance to ensure data accuracy and reliability, which is crucial for decision-making and control in chemical production.

[0003] In chemical production environments, there are flammable and explosive media and gases. If the explosion-proof performance of the instruments is insufficient, once a leak or malfunction occurs, it can easily lead to an explosion, posing a serious threat to the personal safety of workers and production facilities. This can not only lead to production stoppage and economic losses, but may also cause major catastrophic consequences.

[0004] To address the aforementioned issues, we have made improvements and proposed a high-safety-performance explosion-proof structure for chemical instruments. Utility Model Content

A screw is movably connected to the inner cavity of the adjusting box through a bearing. A threaded sleeve is threaded to the surface of the screw. A connecting rod is fixedly connected to the top of the threaded sleeve. An explosion-proof shell is fixedly connected to the inner side of the connecting rod. The explosion-proof shell includes a stainless steel base layer, an inner functional layer, and an outer functional layer. The inner functional layer includes an antistatic ABS plastic layer and a reinforced nylon layer. The outer functional layer includes an aluminum alloy layer and a high-performance fiberglass layer.

[0006] Preferably, the instrument body is provided at the middle of the top of the base plate, the explosion-proof housing is provided on the outside of the instrument body, and the front surface of the explosion-proof housing is inlaid with explosion-proof glass.

[0011] Compared with the prior art, this utility model provides a high-safety explosion-proof structure for chemical instruments, which has the following beneficial effects:

[0012] 1. This chemical instrument uses a high-safety explosion-proof structure. The output end of the servo motor drives the screw to rotate. The screw uses the thread to drive the screw sleeve to move inward. The screw sleeve drives the connecting rod to move inward. The connecting rod drives the explosion-proof housing to move inward, so that the inner sides of the two explosion-proof housings come into contact with each other. The explosion-proof housings on both sides cover the instrument body, effectively resisting the impact and flames generated by the explosion, while preventing the intrusion of corrosive substances and protecting the internal electrical components and measuring equipment from damage. In addition, it ensures that the instrument body operates stably in harsh environments, thereby improving the safety and reliability of chemical production.

[0013] 2. This chemical instrument uses a high-safety explosion-proof structure, featuring an inner functional layer consisting of a stainless steel base, an anti-static ABS plastic layer, and a reinforced nylon layer, and an outer functional layer consisting of an aluminum alloy layer and a high-performance fiberglass layer. The stainless steel base possesses advantages such as corrosion resistance, high temperature resistance, high strength, and good toughness, enabling it to withstand considerable explosion pressure and ensuring the explosion-proof housing will not shatter or crack under explosive impact. The anti-static ABS plastic layer has excellent impact resistance, shock resistance, and anti-static properties, preventing internal electrical components from exploding due to static sparks, while also resisting the impact and vibration of an explosion. The reinforced nylon layer possesses high strength, high wear resistance, corrosion resistance, and good temperature resistance, providing additional mechanical strength and ensuring the long-term stability of the explosion-proof housing in chemical environments. The aluminum alloy layer possesses advantages such as high strength, light weight, corrosion resistance, and good thermal and electrical conductivity, which can reduce the overall weight while maintaining sufficient mechanical strength, preventing the explosion-proof housing from rusting in corrosive environments. It also helps dissipate internal heat, reducing the risk of explosion. The high-performance fiberglass layer is waterproof, fireproof, corrosion-resistant, high-strength, and has good insulation properties. It not only prevents external moisture, flames, or chemicals from corroding the internal instruments but also ensures that the explosion-proof housing will not burn in a fire, further reducing the risk of explosion. Simultaneously, it ensures that the explosion-proof housing maintains structural integrity under external impact, preventing current from entering from the outside and protecting the internal electrical system. Through the combination of these structures, the explosion-proof performance of the housing is significantly improved, ensuring the stable operation of the instrument body in hazardous environments.

The explosion-proof housing 4 covers the outer side of the instrument body 10. Explosion-proof glass 5 is inlaid on the front surface of the explosion-proof housing 4. A servo motor 7 for driving the screw 8 to rotate is fixedly connected to the outer side of the adjustment box 2. The output end of the servo motor 7 is fixedly connected to the outer side of the screw 8. A sliding groove 12 is provided at the bottom of the inner cavity of the adjustment box 2.

A through groove 6 is provided at the top of the adjustment box 2. The top of the threaded sleeve 9 penetrates the inner cavity of the through groove 6 and extends to the top of the adjustment box 2.

[0023] Through the above technical solution, the output end of the servo motor 7 drives the screw 8 to rotate. The screw 8 uses the thread to drive the screw sleeve 9 to move inward. The screw sleeve 9 drives the connecting rod 3 to move inward. The connecting rod 3 drives the explosion-proof housing 4 to move inward, so that the inner sides of the two explosion-proof housings 4 come into contact with each other. The two explosion-proof housings 4 cover the instrument body 10, effectively resisting the impact and flame generated by the explosion, while preventing the intrusion of corrosive substances and protecting the internal electrical components and measuring equipment from damage. In addition, it ensures that the instrument body 10 operates stably in harsh environments, thereby improving the safety and reliability of chemical production. By setting the explosion-proof glass 5, the inner cavity of the explosion-proof housing 4 can be viewed in real time. By setting the slider 11 and the slide groove 12, the stability of the screw sleeve 9 during horizontal movement can be effectively improved.

[0024] Specifically, the explosion-proof housing 4 includes a stainless steel base layer 401, an inner functional layer 402, and an outer functional layer 403. The inner functional layer 402 includes an antistatic ABS plastic layer 4021 and a reinforced nylon layer 4022. The outer functional layer 403 includes an aluminum alloy layer 4031 and a high-performance fiberglass layer 4032. The inner functional layer 402 is disposed inside the stainless steel base layer 401, and the outer functional layer 403 is disposed outside the stainless steel base layer 401. The reinforced nylon layer 4022 is disposed inside the stainless steel base layer 401, the antistatic ABS plastic layer 4021 is disposed inside the reinforced nylon layer 4022, the aluminum alloy layer 4031 is disposed outside the stainless steel base layer 401, and the high-performance fiberglass layer 4032 is disposed outside the aluminum alloy layer 4031.

[0025] Through the above technical solutions, the stainless steel base layer 401 possesses advantages such as corrosion resistance, high temperature resistance, high strength, and good toughness, enabling it to withstand considerable explosion pressure and ensuring that the explosion-proof housing 4 will not shatter or crack under explosive impact. The antistatic ABS plastic layer 4021 has good impact resistance, shock resistance, and antistatic properties, preventing internal electrical components from exploding due to sparks generated by static electricity, while also resisting the impact and vibration generated by the explosion. The reinforced nylon layer 4022 has high strength, high wear resistance, corrosion resistance, and good temperature resistance, providing additional mechanical strength and ensuring the long-term stability of the explosion-proof housing 4 in chemical environments. The aluminum alloy layer 4031 has high strength, light weight, rust resistance, and good thermal and electrical conductivity. These advantages reduce the overall weight while maintaining sufficient mechanical strength, preventing the explosion-proof housing 4 from rusting in corrosive environments. It also helps dissipate internal heat, reducing the risk of explosion. The high-performance fiberglass layer 4032 possesses waterproof, fireproof, corrosion-resistant, high-strength, and good insulation properties. It not only prevents external moisture, flames, or chemicals from corroding the internal instruments but also ensures that the explosion-proof housing 4 will not burn in a fire, further reducing the risk of explosion. Simultaneously, it ensures that the explosion-proof housing 4 maintains structural integrity under external impact, preventing current from entering from the outside and protecting the internal electrical system. Through the combination of these structures, the explosion-proof performance of the explosion-proof housing 4 is significantly improved, ensuring the stable operation of the instrument body 10 in hazardous environments.

[0026] In use, the output end of the servo motor 7 first drives the screw 8 to rotate. The screw 8 uses the thread to drive the screw sleeve 9 to move inward. The screw sleeve 9 drives the connecting rod 3 to move inward. The connecting rod 3 drives the explosion-proof housing 4 to move inward, so that the inner sides of the two explosion-proof housings 4 come into contact with each other. The two explosion-proof housings 4 cover the instrument body 10, effectively resisting the impact and flame generated by the explosion, while preventing the intrusion of corrosive substances and protecting the internal electrical components and measuring equipment from damage. In addition, it ensures that the instrument body 10 operates stably in harsh environments, thereby improving the safety and reliability of chemical production. Through the cooperation of the stainless steel base layer 401, the inner functional layer 402 and the outer functional layer 403, the explosion-proof performance of the explosion-proof housing 4 is significantly improved, ensuring the stable operation of the instrument body 10 in hazardous environments.
