Description

Technical Field

[0001] This utility model belongs to the field of modified asphalt shearing modification technology, specifically relating to an environmentally friendly smoke removal and splash prevention safety device for a high-speed asphalt shearing machine. Background Technology

[0002] With the booming development of my country's transportation industry, stricter requirements have been placed on the performance and environmental friendliness of road materials such as asphalt. Against this backdrop, asphalt modification, as an effective means to significantly improve asphalt quality, has attracted close attention and favor from researchers. In laboratory environments, high-speed shearing technology is widely used due to its high efficiency, becoming one of the important methods for asphalt modification. However, while high-speed asphalt shearing machines can effectively improve asphalt performance during the modification process, they also have several significant defects and drawbacks that cannot be ignored. Specifically, the high-speed rotating shearing blades of this equipment experience intense friction with the asphalt, resulting in a large amount of asphalt splashing, which not only causes raw material loss but may also contaminate the operating environment and surrounding equipment. Furthermore, the high temperature and friction generated during the shearing process often lead to the release of large amounts of harmful fumes, which not only endanger the health of operators but also worsen the working environment and increase safety hazards. Most importantly, high-speed shearing operations are inherently high-risk; if equipment protection measures are inadequate or operations are not standardized, safety accidents can easily occur, seriously threatening personnel safety.

[0003] Based on the above analysis, the existing technology mainly suffers from the following technical problems: Asphalt splattering easily occurs when using a high-speed shearing machine, and the high temperature of the asphalt can easily burn the skin of test personnel. Furthermore, the asphalt fumes generated during shearing, along with the noise, will further harm the health of the test personnel. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: according to Figures 1-3 The above-displayed environmentally friendly smoke removal and splash prevention safety device for a high-speed asphalt shearing machine includes a housing 9, an asphalt fume filter 8, and an equipment fixator 4. The asphalt fume filter 8 is connected to the housing 9. The equipment fixator 4 is fixedly connected to the lower part of the housing 9 for stabilizing the high-speed asphalt shearing machine.

[0026] In practical use, the high-speed asphalt shearing machine is fixed inside the housing 9 by the equipment holder 4. After the asphalt to be sheared is placed in the high-speed asphalt shearing machine, it is started to shear the asphalt. The splashing asphalt and noise generated during the shearing process are contained within the housing 9; the generated fumes are fully filtered through the asphalt fume filter 8 before being discharged. This invention not only ensures the safe conduct of the test process and achieves safe operation of the asphalt shearing process, but also reduces the harm to the health of test personnel during the shearing test. By filtering and purifying the asphalt fumes generated during the shearing process through the asphalt fume filter 8, the large amount of toxic fumes emitted during the test is effectively reduced, minimizing the harm to test personnel and protecting the natural environment on which we depend for survival. In some embodiments, the asphalt fume filter 8 includes a housing 8-6, a venting top cover 8-5, and a filter layer; the venting top cover 8-5 is detachably connected to the upper end of the housing 8-6; the filter layer is detachably connected to the inner wall of the housing 8-6.

[0027] Furthermore, the shell 8-6 ​​is an open-top and open-bottom ring structure; the filter layer includes a filter screen 8-1, an activated carbon filter layer 8-2, an activated alumina filter layer 8-3, and a hydrated lime powder filter layer 8-4; the filter screen 8-1, the activated carbon filter layer 8-2, the activated alumina filter layer 8-3, and the hydrated lime powder filter layer 8-4 are detachably connected with gaps on the inner wall of the shell 8-6 ​​in sequence from bottom to top.

[0028] Furthermore, the filter screen 8-1 is a precision filter screen with a mesh size of 550 to 640.

[0029] In actual use, the lower end of the shell 8-6 ​​is sealed to the upper end of the box 9; the upper end of the shell 8-6 ​​is connected to the vent cover 8-5. When the high-speed asphalt shearing machine shears asphalt, the generated flue gas is filtered from the upper end of the box 9 through layers of filter screen 8-1, activated carbon filter layer 8-2, activated alumina filter layer 8-3, and hydrated lime powder filter layer 8-4, and then discharged through the vent holes on the top surface of the vent cover 8-5. Among them, filter screen 8-1 is mainly used to intercept large particulate splashes and primary oil mist; activated carbon filter layer 8-2 is used for adsorption and filtration of volatile organic compounds (VOCs) and malodorous gases; activated alumina filter layer 8-3 is used for deep filtration of moisture and acidic gases; and hydrated lime powder filter layer 8-4 is used for chemical neutralization filtration of sulfur dioxide (SO2) and hydrogen halides (HCl / HF).

[0030] In some embodiments, four device holders 4 are provided, and the four device holders 4 are respectively connected to the four corners of the bottom of the housing 9. The device holder 4 includes a fixed base 10, an adjustable arm 11, a claw assembly 12, and a locking mechanism 13. One end of the adjustable arm 11 is detachably connected to the housing 9 through the fixed base 10. The claw assembly 12 is rotatably connected to the other end of the adjustable arm 11. The locking mechanism 13 is connected between the adjustable arm 11 and the claw assembly 12 and is used for locking and unlocking the claw assembly 12.

[0031] In this embodiment, the equipment holder 4 is made of high-temperature and corrosion-resistant metal materials, such as Haynes 242 alloy, Haynes 25 (L605), and GH3625 alloy. It can be bent and deformed to firmly grip the high-speed asphalt shearing machine, ensuring the integrity and safety of the test process. The fixed base 10 is made of Q235B steel plate with a thickness of 13-17mm, and is connected to the four corners of the housing 9 by high-strength bolts. The adjustable boom 11 is a 304 stainless steel telescopic boom, hinged above the fixed base 10, and driven to extend and retract by a screw nut. The claw assembly 12 is a multi-section claw 14 made of heat-resistant aluminum alloy. In this embodiment, two sections of claw 14 are used, and the two sections are hinged together by a hinge shaft. A silicone anti-slip layer is provided on the gripping surface of the claw 14, and the end of the adjustable boom 11 is connected by a... The universal joint is connected to the claw assembly 12; a locking mechanism 13 is also connected between the adjustable boom 11 and the claw assembly 12. The locking mechanism 13 adopts the existing M20 manual screw tightener; the M20 manual screw tightener passes through the claw hinge shaft in the adjustable boom 11 and the claw assembly 12; in addition, the device retainer 4 has an anti-stick protection function. The surface of the claw assembly 12 is coated with Teflon coating with a thickness of 48-52μm, so that asphalt droplets falling on the claw assembly 12 can automatically slide off.

[0032] In practical applications, the adjustable arms 11 at the four corners of the housing 9 are adjusted to firmly grip the asphalt test block to be sheared, and the locking mechanism 13 is used to lock it, thus fixing the high-speed asphalt shearing machine inside the device for asphalt shearing preparation tests.

[0033] In some embodiments, the housing 9 includes a frame 1, a housing panel 2, and a door 6; the frame 1 is a rectangular frame; the door 6 is located on the front side of the frame 1, and housing panels 2 are connected to the other sides of the frame 1; an asphalt fume filter 8 is connected to the housing panel 2 located at the top of the frame 1; and an electrical wire through hole 7 is opened at the lower part of the housing panel 2 located on the rear side.

[0034] Furthermore, the frame 1 is made of high-temperature resistant metal; the box panel 2 is made of polytetrafluoroethylene (PTFE) sheet.

[0035] In practical use, the chamber 9 adopts the above-mentioned structure, which not only facilitates experimental operation and ensures experimental safety, but also ensures that debris and harmful gases generated during the process are treated by the upper asphalt fume filter 8 before being discharged, thus protecting the experimental environment. The chamber panel 2 is made of transparent, noise-reducing, high-temperature resistant, and corrosion-resistant polytetrafluoroethylene (PTFE) board, which enhances the visibility of the asphalt shear test process and reduces the noise generated during the test, ensuring the safe operation of the test process.

[0036] In this embodiment, frame 1 is made of high-temperature resistant metals such as Haynes 242 alloy, Haynes 25 (L605), and GH3625 alloy.

[0037] In some embodiments, the door 6 is a single-axis rotatable door; a door lock 5 is installed on the door 6 to tightly close the door 6 to the frame 1.

[0038] Furthermore, the door lock 5 uses a metal push-button latch.

[0039] In practical use, a single-axis revolving door is adopted. The core structure of a single-axis revolving door is a combination of a door frame, a pivot, and a door panel. It does not require a complex linkage mechanism or electronic control system, has a simple structure, fewer points of failure, and also has good heat insulation and sound insulation effects.

[0040] The door lock 5 uses a metal push-button latch, which not only meets the requirements and is easy to operate, but also has a low cost.

[0041] In some embodiments, high-temperature resistant rubber sealing rings 3 are provided at the connection between the frame 1 and the box panel 2, and at the connection between the frame 1 and the door 6.

[0042] In actual use, the use of sealing rings makes the sealing performance of the box 9 better, and the toxic gas inside the box 9 is not easy to escape.

[0043] Example 2: like Figures 1-3 As shown, the environmentally friendly smoke removal and splash prevention safety device for a high-speed asphalt shearing machine of this utility model includes a rectangular high-temperature resistant metal frame 1 with flat sides and a polytetrafluoroethylene (PTFE) plate embedded in the frame as a box plate 2. The connection between the PTFE plate and the high-temperature resistant metal frame 1 is made of a high-temperature resistant rubber sealing ring 3. The front of the high-temperature resistant metal frame 1 is a single-axis rotatable door 6, which is equipped with a metal push-button door lock. The bottom side of the high-temperature resistant metal frame 1 is made of a high-temperature resistant rubber sealing ring 3. A grab-shaped equipment fixing device 4 is connected to the bottom side frame of the high-temperature resistant metal frame 1. An electrical wire through hole 7 is opened on the rear side of the PTFE plate. An asphalt fume filter 8 is installed in the center of the upper side of the PTFE plate.

[0044] It should be noted that the cuboid high-temperature resistant metal frame 1 is composed of 12 high-temperature resistant steel pipes connected together. The dimensions of the high-temperature resistant steel pipes, which serve as the length, width, and height of the cuboid, can be set as needed. In this embodiment, the lengths of the high-temperature resistant steel pipes, which serve as the length, width, and height, are 400mm, 300mm, and 900mm, respectively. The single-axis rotatable door frame 6 is composed of 4 high-temperature resistant steel pipes connected together, one of which is shared with the cuboid high-temperature resistant metal frame 1.

[0045] It should be noted that an asphalt fume filter 8 is installed by making a circular through hole with a diameter of 150mm in the center of the polytetrafluoroethylene (PTFE) plate on the top surface of the housing 9. The connection between the through hole and the asphalt fume filter 8 is sealed with a high-temperature resistant rubber sealing ring 3. A 20mm×20mm square wire through hole 7 is made in the lower part of the rear housing plate 2. The connection between the square wire through hole 7 and the wire should be sealed with a high-temperature resistant rubber sealing ring 3.

[0046] like Figure 2 As shown, in this embodiment, the outer shell 8-6 ​​of the asphalt fume filter 8 is made of polytetrafluoroethylene (PTFE). The bottom layer of the asphalt fume filter 8 is a detachable filter screen 8-1, which has a 600-mesh dense mesh structure. The three middle layers of the asphalt fume filter 8, from bottom to top, are respectively filled with activated carbon filter material 8-2, activated alumina filter material 8-3, and hydrated lime dry powder filter material 8-4. The bottom of the filter material is a detachable filter screen 8-1. The top of the asphalt fume filter 8 is a ventilated top cover 8-5. Each layer of the asphalt fume filter 8 is detachable.

[0047] like Figure 3 As shown, the gripper-shaped device holder 4 is made of high-temperature and corrosion-resistant metal material. It can be bent and deformed to firmly grip the high-speed shearing device, ensuring the integrity and safety of the test process.

[0048] Through asphalt fume detection tests, the average concentration of asphalt fume was only 39.8% after using the device throughout the test, proving that the device can effectively block the diffusion of fume and significantly reduce the concentration of harmful substances in the working environment. After the heating equipment was turned off, the fume dissipation rate was 65.3% faster than that of a fully enclosed device, indicating that the device helps to accelerate ventilation and shorten the residual time of harmful gases.

[0049] Testing revealed a significant difference between the operating environment using this invention and that without it. This invention effectively improves the experimental environment and ensures the safety of operators.
