Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and particularly relates to a microcapsule snow melting agent spraying device. Background Art

[0002] Road traffic is an important part of the national economy. The operation of municipal roads and highways plays a key role in promoting the development of China's economic society. In winter, most parts of China are relatively cold, and the problem of road snow and ice is very serious. According to statistics, nearly 70% of China's territory belongs to the winter snow-covered area, and in some areas, the snow cover time is as long as 3 - 4 months, which causes quite a lot of trouble to 60% of China's expressways. Because road snow and ice not only affect the efficiency of transportation but also pose a great threat to the safety of moving vehicles, resulting in a large number of traffic accidents.

[0003] At present, the commonly used snow removal methods mainly include manual snow removal, mechanical snow removal, and spreading snow melting agents. Manual snow removal is time-consuming and laborious, and is only suitable for small-area snow removal; mechanical snow removal uses snow removal equipment and is mainly suitable for roads that have not been rolled by vehicles. Spraying snow melting agents is a method of melting snow through chemical reactions. It is a one-time snow removal method and cannot continuously melt snow and ice. It needs to be used repeatedly, increasing costs and resource consumption. At the same time, the current mainstream snow melting agents all contain chloride ions, which bring great harm to the road itself and its surrounding environment, mainly reflected in corroding the road surface, steel bars and other auxiliary facilities, polluting the soil and water sources.

[0004] In view of this, scientific research personnel have developed microcapsule snow melting agents, which can be sprayed on the road surface. Since there are many vehicles on traffic roads, especially on expressways, a single spray gun is not suitable for large-area spraying, and traffic control will cause traffic congestion. Therefore, it is necessary to develop a new type of spraying device that can achieve rapid spraying and achieve the snow removal and ice melting effect of self-snow melting on winter road surfaces.

Detailed Embodiments

[0023] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the utility model will be described below with reference to the drawings.

[0024] Such as Figure 1As shown in the figure, a microcapsule snow melting agent spraying device provided by an embodiment of the present invention includes a vehicle body 1 that can be connected to a traction device 00. A walking wheel 2 is provided at the bottom of the vehicle body 1, and a storage tank 3 for accommodating snow melting asphalt liquid is provided at the top. An air compressor 4 is provided above the rear of the vehicle body 1, and a spray rod 5 is provided below. A row of nozzles 6 is provided at the bottom of the spray rod 5. The air outlet pipe of the air compressor 4 is connected to the discharge pipe of the storage tank 3, and the lower end of the discharge pipe is connected to the spray rod 5. The spray rod 5 is connected to the bottom of the vehicle body 1 through a lifting mechanism. In specific applications, the traction device is selected as a flatbed transport trailer. As the trailer moves forward slowly, the snow melting asphalt liquid is pressurized and transported to the spray rod through compressed air, and the spraying area is enlarged through a row of nozzles, so that the snow melting asphalt can be quickly and evenly sprayed onto the road surface to form a snow melting coating.

[0025] In a specific embodiment of the present invention, as shown in Figures 1 and 2, the lifting mechanism includes a lifting cylinder 7 and telescopic structures on both sides thereof. The cylinder body of the lifting cylinder 7 is connected to the vehicle body 1, and the end of the piston rod of the lifting cylinder 7 is connected to the rear side of the middle of the spray rod 5. The upper and lower ends of the telescopic structure are respectively connected to the vehicle body 1 and the two ends of the spray rod 5. The lifting cylinder 7 is controlled by a console in the traction device 00. Among them, the telescopic structure includes an outer sleeve 8 and an inner sleeve 9. The upper end of the outer sleeve 8 is connected to the vehicle body 1, the lower end of the inner sleeve 9 is connected to the spray rod 5, and the upper end of the inner sleeve 9 is inserted into the outer sleeve 8 and the two are in sliding fit. With the sliding fit of the outer sleeve and the inner sleeve, the two ends of the spray rod can be lifted and lowered simultaneously. As the snow melting asphalt liquid is continuously sprayed, the load of the vehicle body decreases continuously, and the height of the spray rod will increase. If the height of the spray rod is not adjusted in time, the spraying amount of the fog seal layer will become larger. Therefore, it is necessary to adjust the height of the spray rod in time through the lifting cylinder to keep the distance between the nozzle and the ground consistent and ensure that the spraying amount meets the requirements.

[0026] Further optimize the above solution, as Figure 2 shown, a rack 10 is provided on the outer wall of the inner sleeve 9 along its length direction, and an opening for a gear 11 to penetrate is provided on the outer wall of the outer sleeve 8. The rack 10 meshes with the gear 11. The two gears 11 are connected through a connecting shaft 12. The two ends of the connecting shaft 12 are connected to the vehicle body 1 through a suspension rod 13. The suspension rod 13 is arranged inside the gear 11. A housing 14 is provided outside the gear 11, and the opening side of the housing 14 is connected to the edge of the opening on the outer sleeve 8. With the meshing of the gears on both sides and the rack, it can ensure that the two ends of the spray rod are lifted and lowered synchronously, further improving the consistency of the spraying amount of all nozzles.

[0027] During specific production, as Figure 1 、 2As shown, the lifting mechanism is connected to the vehicle body 1 through the mounting plate 15, and the mounting plate 15 is detachably connected to the vehicle body 1. Among them, mounting frames (not shown in the figure) are provided around the lifting mechanism. The top of the mounting frame is connected to the mounting plate 15. One end of the mounting plate 15 is rotatably connected to the vehicle body 1, and the other end is detachably connected to the vehicle body 1 through a buckle (not shown in the figure). The lower part of the mounting frame is connected to the vehicle body 1 through a tilting cylinder (not shown in the figure). The tilting cylinder is used to turn the spray bar 5 to a high position and fix it to the bottom of the vehicle body through a pressing plate (not shown in the figure). During construction, the spray bar is lowered to a low position by the tilting cylinder to spray snow melting asphalt close to the ground. After construction is completed, the tilting cylinder is driven to drive the mounting frame to tilt, so that the spray bar is turned to a high position and parallel to the bottom of the vehicle body. At the same time, the discharge pipe uses a flexible hose, which is convenient for adjusting the position at will, and the mounting frame is fixed to the bottom of the vehicle body by using a pressing plate. In this way, turning the spray bar to a high position during transportation can avoid bumping and damaging the spray bar and the nozzle, and can ensure the safety of the main pipe, the spray bar and the nozzle.

[0028] In a specific embodiment of the present invention, as Figure 2 shown, the discharge pipe is connected to the main pipe 16, and the main pipe 16 is connected to the nozzles 6 in the spray bar 5 through a plurality of branch pipes 17; the main pipe 16 is connected to the vehicle body 1 through a traction member 18, and the traction member provides support for the main pipe. The discharge pipe distributes the snow melting asphalt to each branch pipe and nozzle through the main pipe, which can ensure the consistency of the spraying amount of all nozzles. Compared with the snow melting asphalt directly entering the inner cavity of the spray bar through the discharge pipe, it avoids the phenomenon that the snow melting asphalt flows unevenly in the inner cavity of the spray bar, resulting in inconsistent spraying amounts of each nozzle.

[0029] During specific assembly, a stirrer is provided in the storage tank 3, and the motor 19 of the stirrer is arranged on the top of the storage tank 3; a solid material tank 20 for containing the microcapsule anti-icing agent is provided above the storage tank 3. The discharge port of the solid material tank 20 is communicated with the storage tank 3, and a weighing sensor (not shown in the figure) is provided at the discharge port; an asphalt tank 21 for containing emulsified asphalt is provided on the side of the storage tank 3. The bottom discharge port of the asphalt tank 21 is connected to the storage tank 3 through an asphalt pump 22; both the weighing sensor and the asphalt pump 22 are controlled by a control console in the traction device 00. During specific installation, the storage tank, the solid material tank and the asphalt tank are installed on the vehicle body through a fixing frame to ensure safety during transportation. When preparing the snow melting asphalt, the microcapsule anti-icing agent and the cationic emulsified asphalt are mixed evenly in the storage tank. The optimal dosage of the microcapsule anti-icing agent in the storage tank is 12% (the mass ratio of the microcapsule anti-icing agent to the total amount of the microcapsule anti-icing agent and the emulsified asphalt in the storage tank). Using this equipment can prepare the snow melting asphalt at any time according to the construction needs and can avoid the precipitation phenomenon of the snow melting asphalt in the storage tank for a long time.

[0030] During the specific construction, quick-cracking cationic emulsified asphalt is used as the carrier of the microcapsule anti-freezing and ice-melting agent. When sprayed on the road surface, it can form an asphalt film that can prevent water from freezing (i.e., the anti-icing and snow-melting coating). Among them, the preparation steps of the microcapsule anti-freezing and ice-melting agent are as follows:

[0031] The following are the specific steps for preparing the microcapsule anti-freezing and ice-melting agent in small-scale tests. Each parameter can be adjusted according to actual production.

[0032] (1) Take a 100 mL conical flask, add 0.5 mL of ammonia water, 1.5 mL of TEOS (tetraethyl orthosilicate), and 20 mL of absolute ethanol. Use a magnetic stirrer to continuously stir at a speed of 150 r / min for 2 h, and set aside.

[0033] (2) Take a 100 mL beaker, add 4 g of the environmentally friendly anti-freezing and ice-melting agent and 30 mL of absolute ethanol, and then put it into an ultrasonic instrument for ultrasonic dispersion for 30 min.

[0034] (3) Pour it into the conical flask, use a magnetic stirrer to continuously stir at a speed of 200 r / min for 48 h, then centrifuge and wash with alcohol to obtain a precipitate, and vacuum dry at 80 °C for 48 h. After drying, SiO2 microcapsules coated with the environmentally friendly anti-freezing and ice-melting agent are obtained.

[0035] Due to the encapsulation of the microcapsules, the anti-freezing and ice-melting agent in the above-prepared microcapsule anti-freezing and ice-melting agent can continuously precipitate from the capsules when affected by external conditions such as temperature, air, and wheel rolling, achieving the effect of long-term slow release. When sprayed on the road surface, a long-term biomass self-snow-melting coating is formed. During spraying, 0.65 kg / m 2 is selected as the best spraying amount of the coating, and the spray bar height and vehicle driving speed are controlled according to this standard.

[0036] During the specific construction, the construction node of the anti-icing and snow-melting coating is also selected for construction before winter or in the early winter, because at this time the air humidity is high, the temperature is low, and the road surface is wet and negatively charged. The positively charged asphalt particles can quickly adsorb on the negatively charged road surface, and the emulsified asphalt can be demulsified and the asphalt can be precipitated in a short time, so as to achieve the purpose of inhibiting ice layer formation. This kind of coating is suitable for construction under humid or low-temperature conditions, can improve the adhesion and durability of asphalt, and is not affected by moisture. This kind of coating can effectively prevent water from infiltrating and improve the anti-skid performance of the road surface. At the same time, the anti-icing and snow-melting coating can not only melt ice and snow, improve the safety of the road surface, but also play a role in pre-maintaining the road surface and extending the service life of the road surface.

[0037] In summary, the utility model has the advantages of compact structure and good spraying effect. The snow-removing asphalt is obtained by uniformly mixing cationic emulsified asphalt and microcapsule anti-freezing and ice-melting agent in a storage tank, and the snow-removing asphalt is conveyed to a spray bar through compressed air and evenly sprayed onto the road surface through a row of nozzles to form a long-lasting biomass self-melting snow coating. By using the utility model, the snow-removing asphalt can be quickly sprayed on a large area of the road surface. Compared with the chlorine-containing snow-melting agent, the formed anti-icing and snow-melting coating can protect the road and its surrounding environment, extend the service life of the road surface, and protect the pollution and water source. The utility model is particularly suitable for spraying on highways, effectively protecting the safe operation of highways in winter and providing guarantee for the life safety of people and the safety of driving vehicles.
