Description

Technical Field

[0001] This utility model relates to the field of chemical testing technology, and in particular to a safety testing device for hazardous chemicals. Background Technology

[0002] With the acceleration of industrialization, the application of hazardous chemicals in industries such as chemicals, pharmaceuticals, and energy is becoming increasingly widespread, making safety testing particularly important in production, transportation, and storage. Hazardous chemical safety testing equipment can perform component analysis and concentration monitoring on liquid, gaseous, or solid samples, providing crucial technical support for preventing safety accidents and ensuring a safe working environment. This type of equipment not only requires high testing accuracy but also strong adaptability and stability to cope with various complex testing scenarios. Furthermore, due to the corrosive, toxic, flammable, and explosive properties of hazardous chemicals, the structural design of testing equipment must consider safe disposal and cleaning after use to avoid secondary pollution and personnel injury.

[0003] Existing hazardous chemical safety testing equipment typically consists of a main frame, a sample delivery mechanism, a testing unit, a waste liquid treatment unit, and a control system. The sample delivery mechanism often uses corrosion-resistant pipes or belts to transport the sample to the testing unit. The testing unit often integrates technologies such as spectroscopic analysis, chromatographic separation, or electrochemical sensing to achieve rapid determination of sample composition and concentration. The waste liquid treatment unit is responsible for collecting and safely discharging or transporting hazardous liquids generated during the testing process. During operation, the entire system is coordinated by the control system to ensure the stability of the testing process and the accuracy of the data. This type of equipment can operate continuously and achieve high-precision analysis in industrial settings, making it an important tool for hazardous chemical monitoring.

[0004] However, in existing technologies, hazardous chemical safety testing equipment often presents challenges in replacement and cleaning after testing. Due to its largely fixed structural design, the internal components of the sample transport and testing channels are difficult to disassemble quickly, requiring significant manpower and time for cleaning. Furthermore, handling hazardous chemical residues necessitates strict protective measures, increasing operational difficulty and safety risks. This not only affects the equipment's efficiency for reuse but may also compromise the accuracy of subsequent tests due to residue accumulation. Therefore, how to facilitate easier replacement and cleaning of the equipment after testing, while maintaining its testing functionality, remains a crucial technological challenge.

[0027] The quick-release assembly includes a snap-on post 14, which extends and retracts under the action of a quick-release block 16. It works with a limiting post 18 to connect or disconnect the rotating shaft 15 from the pressure roller mechanism 13. The snap-on post 14 is slidably connected to the inner wall of the rotating shaft 15 and connected to the pressure roller mechanism 13. The outer wall of the snap-on post 14 is slidably connected to the quick-release block 16. The outer wall of the quick-release block 16 is threadedly connected to the pressure roller mechanism 13. A spring 17 is sleeved on the outer wall of the snap-on post 14 to provide a reset elastic force for the snap-on post 14. During installation, the snap-on post 14 is pushed to extend automatically. The inner wall of the quick-release block 16 is slidably connected to a limiting post 18. The limiting post 18 is fixedly connected to the outer wall of the snap-on post 14. The outer wall of the rotating shaft 15 is fixedly connected to the pressure roller mechanism 13.

[0028] Specifically, the operator holds the quick-release block 16 and rotates it clockwise or counterclockwise. The quick-release block 16 pushes the latching post 14 to retract against the elastic force of the spring 17. The limiting post 18 slides out of the limiting hole along with the latching post 14, releasing the connection between the rotating shaft 15 and the pressure roller mechanism 13. During installation, the quick-release block 16 is rotated to the inner wall of the pressure roller mechanism 13, and the latching post 14 is rotated. The spring 17 pushes the latching post 14 to automatically reset, completing the installation.

[0029] Reference Figures 1-5 A base 8 is provided on one side of the outer wall of the casing 1. A support frame 7 is fixedly connected to the upper surface of the base 8. A rack block 6 is slidably connected to the inner wall of the support frame 7. A rotating shaft 20 is slidably connected to the inner wall of the support frame 7. A gear 19 is rotatably connected to the outer wall of the rotating shaft 20 and meshes with the rack block 6. The rotation of the gear 19 drives the rack block 6 to move. A rotating shaft 3 22 is fixedly connected to the inner wall of the support frame 7. A connecting rod 21 is rotatably connected to the outer wall of the rotating shaft 3 22. A pressure rod 11 is fixedly connected to the outer wall of the gear 19. A fixing post 23 is fixedly connected to the outer wall of the connecting rod 21. A spring 2 is fixedly connected to the lower surface of the fixing post 23. 4. One end of spring 24 is fixedly connected to the upper surface of base 8. A transition block 10 is fixedly connected to the outer wall of rack block 6. A container 9 is set below the transition block 10. A handle 2 is fixedly connected to the upper surface of housing 1. A pump cover 4 is slidably connected to the outer wall of pump head 3. A conveying pipe 5 is attached to the inner wall of pump cover 4.

A rack block 6 is attached to the outer wall of connecting rod 21. A pressure rod 11 is rotatably connected to the inside of support frame 7. One end of spring 17 is fixedly connected to the outer wall of limit post 18. The other end of spring 17 is fixedly connected to the inner wall of quick release block 16.

[0030] Specifically, the housing 1 is supported by the base 8. Inside the support frame 7 on the base 8, the gear 19 on the outer wall of the rotating shaft 20 meshes with the rack block 6. The gear 19 is manually driven to rotate by the pressure rod 11, which drives the rack block 6 to move up and down. The rotating shaft 3 22 inside the support frame 7 is hinged to the connecting rod 21. The fixed column 23 on the connecting rod 21 is elastically supported by the spring 24.

[0031] Working principle: When the hazardous chemical testing equipment needs to replace pump parts or be cleaned, the operator only needs to hold the quick release block 16 and rotate it clockwise or counterclockwise. The quick release block 16 pushes the latching column 14 inward to overcome the elastic force of the spring 17 and retracts. The limiting column 18 slides out of the original limiting hole along with the latching column 14, so that the connection between the rotating shaft 15 and the pressure roller mechanism 13 is released. During installation, the quick release block 16 is rotated to the inner wall of the pressure roller mechanism 13, and the latching column 14 is rotated. The spring 17 pushes the latching column 14 to automatically reset, completing the installation.

[0032] In addition, when the height of the testing equipment needs to be adjusted, one side of the housing 1 is supported by the base 8. A support frame 7 is fixed on the upper surface of the base 8. A rack block 6 and a rotating shaft 20 are set inside the support frame 7. A gear 19 is rotatably installed on the outer wall of the rotating shaft 20 and meshes with the rack block 6. The rotation of the gear 19 drives the rack block 6 to move up and down. A rotating shaft 3 22 is also fixed inside the support frame 7. A connecting rod 21 is hinged to the outer wall of the rotating shaft 3 22. A fixed column 23 is provided on the connecting rod 21 and elastic support is achieved by a spring 24. A pressure rod 11 is provided on the outer wall of the gear 19 for manually driving the gear 19 to rotate.
