Description

Technical Field

[0001] This utility model is a honeycomb activated carbon bag, belonging to the field of activated carbon technology. Background Technology

[0002] Honeycomb activated carbon is made from high-quality coal-based activated carbon, pressed using a honeycomb mold, and activated and fired at high temperature. It features a large surface area, low pore resistance, well-developed micropores, high adsorption capacity, and long service life, making it widely used in air pollution control. The honeycomb activated carbon adsorption method involves contacting waste gas with porous activated carbon that has a large surface area, causing pollutants in the waste gas to be adsorbed and decomposed, thus achieving purification. When placing honeycomb activated carbon, it is necessary to use honeycomb activated carbon bags for placement.

[0003] Publication number CN209530457U mentions a honeycomb activated carbon bag that introduces harmful gases from the outside through vents in a fixed cylinder, thereby adsorbing the harmful gases. A positioning rod connects to the positioning cylinder, and under the action of a support spring, the fixing ring drives the plug-in rod to engage with the locking block, thus fixing the base plate. However, this device does not have a spring buffer inside the activated carbon bag, and the honeycomb activated carbon body directly bears external vibration and impact, which is prone to cracking or deformation. Moreover, in environments with large temperature changes, the difference in thermal expansion and contraction between the outer shell and the honeycomb activated carbon body may cause stress concentration and structural damage. There is an urgent need for a honeycomb activated carbon bag to solve the above problems. Utility Model Content

An internal threaded ring is fixed to the upper end of the mounting base, and the internal threaded ring is screwed into the threaded groove. A conical positioning seat is fixed to the upper end of the mounting base, and a fixed outer cylinder is longitudinally fixed in the middle of the conical positioning seat. A through-hole is formed at the lower end of the side surface of the fixed outer cylinder. An elliptical buffer groove is provided, in which the inner buffer rod is slidably inserted into the fixed outer cylinder. A pin hole is provided through the lower end of the side surface of the inner buffer rod. An outer sliding ring and a spring sliding seat are slidably fitted on the lower end of the outer cylinder.

A honeycomb activated carbon body is provided on the upper end of the mounting seat, and the upper end of the honeycomb activated carbon body abuts against the buffer pad.

[0006] Furthermore, the outer shell of the charcoal bag has honeycomb ventilation holes on its annular side.

[0008] Furthermore, the pin passes through the elliptical buffer groove and the pin hole.

[0009] Furthermore, the upper end of the outer slip ring is fixed to the spring sliding seat.

[0010] Furthermore, a rubber buffer outer cylinder is fixed to the outer side of the mounting base, and the rubber buffer outer cylinder slides against the inner wall of the carbon bag shell.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-3 This utility model provides a technical solution: a honeycomb activated carbon bag, including a carbon bag shell 1, a mounting base 6, and a buffer inner rod 12. A buffer pad 2 is attached to the upper end of the inner wall of the carbon bag shell 1. A threaded groove 4 is formed at the lower end of the inner wall of the carbon bag shell 1. An internal threaded ring 5 is fixed to the upper end of the mounting base 6, and the internal threaded ring 5 is screwed into the threaded groove 4. A conical positioning seat 9 is fixed to the upper end of the mounting base 6. A fixed outer cylinder 10 is longitudinally fixed in the middle of the conical positioning seat 9. An elliptical buffer groove 11 is formed through the lower end of the side surface of the fixed outer cylinder 10. The buffer inner rod 12 is slidably inserted into the fixed outer cylinder 10. A pin hole 13 is formed through the lower end of the side surface of the buffer inner rod 12. An outer sliding sleeve is slidably fitted on the lower end of the outer surface of the fixed outer cylinder 10. The outer ring 14 and the spring sliding seat 16 are connected by a pin 15 through the side surface of the outer ring 14. The upper end of the outer cylinder 10 is fixedly fitted with a spring fixing seat 18. A spring 17 is provided between the lower end of the spring fixing seat 18 and the spring sliding seat 16. The upper end of the buffer inner rod 12 is horizontally fixed with a mounting seat 19. A honeycomb activated carbon body 21 is provided on the upper end of the mounting seat 19, and the upper end of the honeycomb activated carbon body 21 abuts against the buffer pad 2. This design solves the problem that the original device did not have a spring buffer inside the activated carbon bag. The honeycomb activated carbon body directly bears the external vibration and impact, which is easy to break or deform. In environments with large temperature changes, the difference in thermal expansion and contraction between the outer shell and the honeycomb activated carbon body may cause stress concentration and structural damage.

[0016] In the first embodiment of this utility model: the annular side of the charcoal bag shell 1 is provided with honeycomb ventilation holes 3. The added honeycomb ventilation holes 3 do not affect the passage of external gas through the honeycomb activated carbon body 21. A fixing ring 7 is fixed to the annular side of the charcoal bag shell 1. The fixing ring 7 is connected and fixed to the mounting base 6 by multiple wing bolts 8. The addition of the fixing ring 7 and the mounting base 6 by multiple wing bolts 8 can achieve indirect fixation between the charcoal bag shell 1 and the mounting base 6.

[0017] The pin 15 passes through the elliptical buffer groove 11 and the pin hole 13. The upper end of the outer slip ring 14 is fixed to the spring sliding seat 16. By adding the pin 15, which passes through the elliptical buffer groove 11 and the pin hole 13, the pin 15 can indirectly connect the outer slip ring 14 and the lower end of the buffer inner rod 12. Thus, when the buffer inner rod 12 moves up and down, the outer slip ring 14 and the spring sliding seat 16 can drive the spring 17 to compress or rebound. A rubber buffer outer cylinder 20 is fixed to the outer side of the mounting base 19. The rubber buffer outer cylinder 20 slides against the inner wall of the carbon bag shell 1. By adding the rubber buffer outer cylinder 20 and sliding against the inner wall of the carbon bag shell 1, direct contact between the side surface of the honeycomb activated carbon body 21 and the inner wall of the carbon bag shell 1 can be prevented.

[0018] As a second embodiment of this utility model: In actual use, the buffer pad 2 can protect the upper side of the honeycomb activated carbon body 21, and the rubber buffer outer cylinder 20 can indirectly protect the side surface of the honeycomb activated carbon body 21 through the mounting base 19. When the mounting base 6 is subjected to the force from below, it will not be directly transmitted to the honeycomb activated carbon body 21, but will be transmitted to the spring fixing seat 18 through the conical positioning seat 9. The spring fixing seat 18 can transmit the force to the spring 17 for buffer absorption (in this process, the lower end of the spring 17 drives the outer slip ring 14 and the spring sliding seat 16 to move slightly up and down, and transmits the force to the buffer inner rod 12 through the pin 15, so that the buffer inner rod 12 transmits the force to the honeycomb activated carbon body 21 and the buffer pad 2 through the mounting base 19). At this time, the spring 17 can absorb external vibration and impact, and prevent the honeycomb activated carbon body 21 from breaking or deforming due to mechanical vibration or impact. In environments with large temperature variations, the spring 17 buffer structure can compensate for the difference in thermal expansion and contraction between the carbon bag shell 1 and the honeycomb activated carbon body 21 through its elastic properties, thereby avoiding stress concentration caused by temperature changes.

[0019] The following figure shows the experimental data verifying the spring 17 buffer structure under temperature variation:
