Description

Technical Field

[0001] The present invention relates to the technical field of anti-icing material production, and in particular to a production method and production equipment of a slow-release long-acting anti-icing material. Background Art

[0002] Anti-icing asphalt pavement refers to a pavement with an anti-freezing effect formed by adding anti-icing materials with a freezing point lowering effect to asphalt pavement materials. The effective ingredient of the anti-icing material is mainly freezing point lowering salt. It is easy to use and can be added to the pavement material in advance before asphalt pavement paving or maintenance and repair and used for asphalt pavement paving. It has a good effect of delaying the accumulation of snow and ice on the road surface.

[0003] At present, in the production process of slow-release long-acting anti-icing materials, all raw materials are mixed and stirred only by a group of stirring paddles, and the stirring efficiency is very limited, which cannot effectively improve the stirring efficiency of the production equipment; and when the raw materials of the slow-release long-acting anti-icing materials are mixed and stirred, stirring is usually performed directly by stirring paddles, and the various raw materials of the slow-release long-acting anti-icing materials are often difficult to mix quickly. Not only that, the raw materials at different depths in the stirring bin cannot flow and mix quickly with each other, resulting in a very limited stirring effect of the raw materials of the slow-release long-acting anti-icing materials; at the same time, when the production equipment discharges the anti-icing materials after stirring, it is unable to transport the incompletely mixed mixed raw materials back to the stirring bin, thereby reducing the use effect of the entire production equipment and failing to effectively promote the mixing effect between the various raw materials of the anti-icing materials.

[0022] 1. When the control driving device of the present invention drives the first circular plate to rotate, the four groups of first rotating rods rotate along with the first circular plate, and the anti-icing material mixed raw materials inside the mixing chamber are stirred during the process. Moreover, since the large gear is fixed on the mounting ring, when the first rotating rod rotates around the second rotating rod as the center, the large gear and the small gear will drive the first rotating rod to rotate, so that the first rotating rod drives the outer sleeve and the stirring rod outside the outer sleeve to rotate together, thereby stirring the anti-icing material mixed raw materials inside the mixing chamber, which can effectively improve the stirring efficiency of the production equipment for the anti-icing material mixed raw materials.

[0023] 2. In the present invention, when the first circular plate drives the first rotating rod to rotate, the first circular plate can also drive the annular bin to rotate on the outside of the material passing pipe through the first rotating rod. When the annular bin rotates, the connecting slider will move along the path of the wavy chute inside the wavy chute, which makes the annular bin continuously move back and forth during the rotation, thereby driving the outer sleeve and the stirring rod outside the outer sleeve to continuously move up and down. At this time, the first rotating rod also drives the outer sleeve to rotate, and then the outer sleeve and the stirring rod also continuously move back and forth during the rotation, which can greatly improve the mixing efficiency between the various raw materials of the anti-icing material, and can also allow the raw materials at different depths in the stirring bin to quickly flow and mix with each other, fully ensuring the stirring and mixing effect of the production equipment on the raw materials of the anti-icing material.

In the process of stirring and mixing the various raw materials of the anti-icing material of the present invention, the solenoid valve is opened to allow the mixed raw materials in the stirring bin to enter the feed pipe through the guide pipe, and then the feed pipe cooperates with the first spiral feed paddle to transport the mixed raw materials into the mixing bin. During the process, the comb-shaped stirring plate stirs and combs the mixed raw materials that fall into the mixing bin, and then gradually pushes the mixed raw materials into the feed pipe through the stirring blades, and then returns to the interior of the mixing bin through the feed pipe, so that the mixed raw materials are stirred by multiple stirring structures, which can not only realize the re-transportation of the mixed raw materials that are not fully mixed into the stirring bin, ensuring the use effect of the entire production equipment, but also effectively further promote the mixing effect between the various raw materials of the anti-icing material.

[0037] First, it is clear that the main components of the anti-icing material that lowers the freezing point to -35°C are A, B, C, and D, and the weight ratio of the four is 80:10:7:3;

[0038] 2. Component A mainly includes one or two inorganic salts such as sodium chloride, magnesium chloride, calcium chloride or acetate, as low freezing point factors; component B mainly includes one or two of high-quality zeolite, nano-silicon dioxide, nano-zinc dioxide, nano-mineral powder, etc., as carriers of anti-icing materials; component C mainly includes one or two or more slow-release agents such as fatty acid slow-release agents, sodium formate slow-release agents, and silica sol slow-release agents, which mainly play a slow-release role; component D mainly includes one or two or more fused rubber graphene, high molecular polyethylene, SBS, EPS, etc., to achieve a coating effect of cracking and releasing at negative temperatures and closing and not releasing at positive temperatures;

[0042] A material return mechanism is provided on both sides of the main support frame 1. A material passage 21 connected to the bottom of the mixing bin 3 is installed at the center of the top of the mixing bin 2, and a first circular plate 22 is sleeved on the outside of the material passage 21. A first bearing 23 is installed on the top of the inner wall of the mixing bin 2. The inner ring of the first bearing 23 is fixedly connected to the outer ring of the first circular plate 22. A stirring assembly 24 is provided below the first circular plate 22. A driving device 27 for driving the first circular plate 22 to rotate is provided on the top of the outer side of the mixing bin 2.

[0043] A second servo motor 32 is installed at the center position of the top of the mixing bin 3, and the output end of the second servo motor 32 extends to the interior of the mixing bin 3 and is installed with a second rotating rod 33.

A second circular plate 36 is installed at the top end of the outer side of the second rotating rod 33, and a comb-shaped stirring plate 37 and a stirring blade 38 are respectively installed at the edge position of the bottom of the second circular plate 36.

[0044] Furthermore, the stirring assembly 24 includes a second bearing 241, a first rotating rod 242, a small gear 243, a mounting ring 244, a large gear 245 and an L-shaped plate 246. Four groups of second bearings 241 are evenly installed at a non-center position on the top of the first circular plate 22, and the inner sides of the four groups of second bearings 241 are all installed with a first rotating rod 242. The top end of the outer side of the first rotating rod 242 is installed with a small gear 243. A mounting ring 244 is installed at the middle position of the top of the stirring chamber 2, and a large gear 245 that meshes with the four groups of small gears 243 is installed at the bottom end of the outer side of the mounting ring 244. Four groups of L-shaped plates 246 are evenly installed at the edge position of the bottom of the first circular plate 22, and a reciprocating lifting assembly 25 is provided at the bottom of the L-shaped plate 246.

[0045] Furthermore, the reciprocating lifting assembly 25 includes an annular bin 251, a third bearing 252, an outer sleeve 253, a connecting slider 254, a wavy chute 255, a stirring rod 256, a limiting chute 257 and a limiting slider 258. The outer side of the feeding pipe 21 is provided with an annular bin 251, and four groups of third bearings 252 are evenly installed at the edge position of the bottom of the annular bin 251. The inner ring of the third bearing 252 is provided with an outer sleeve 253. Several groups of stirring rods 256 are installed on the outer side of the outer sleeve 253. The outer sleeve 253 is provided on the first rotating rod 2 42, a limiting groove 257 is provided on the top of the outer side of the first rotating rod 242, and the two ends of the limiting groove 257 are fixedly connected to the L-shaped plate 246 and the annular warehouse 251 respectively. A wavy groove 255 is provided at the bottom of the outer side of the feeding pipe 21, and a connecting slider 254 that cooperates with the wavy groove 255 is symmetrically installed on the top of the inner ring of the annular warehouse 251. A limiting groove 257 is symmetrically provided on the top of the outer side of the outer sleeve 253, and a limiting slider 258 that cooperates with the limiting groove 257 is symmetrically installed on the outer side of the first rotating rod 242.

[0046] Furthermore, the material return mechanism includes a feed pipe 11, which is provided with two groups of feed pipes 11, and the two groups of feed pipes 11 are respectively located on both sides of the mixing bin 2, a first spiral feed paddle 13 is provided inside the feed pipe 11, and a first servo motor 12 for driving the first spiral feed paddle 13 to rotate is installed at the bottom of the feed pipe 11, and a discharge port 14 connected to the interior of the mixing bin 3 is provided at the top end of the outer side of the feed pipe 11, and an electromagnetic valve 16 is symmetrically installed at the bottom end of the outer side of the mixing bin 2, and a guide tube 15 is installed at the output end of the electromagnetic valve 16, and the bottom end of the guide tube 15 is connected to the inner bottom of the feed pipe 11.

[0047] Furthermore, the inner bottom of the mixing bin 3 gradually thickens from the center to the edge, and the mixing bin 3 and the stirring bin 2 are fixedly connected by a flange, which helps the mixed raw materials inside the mixing bin 3 to flow more easily into the feed pipe 21.

[0048] Furthermore, a feed hole 39 is symmetrically opened on the top of the second circular plate 36, and a second material guide funnel 31 cooperating with the feed hole 39 is symmetrically installed on both sides of the top of the mixing bin 3, which helps to add the raw materials in the second material guide funnel 31 into the mixing bin 3 in a quantitative manner each time.

[0049] Furthermore, the driving device 27 includes a driving motor, a driving gear and an annular rack. An annular rack is installed at the edge of the top of the first circular plate 22, a driving motor is installed at the top of the outer side of the mixing chamber 2, and the output shaft of the driving motor is installed with a driving gear that meshes with the annular rack, which helps to drive the first circular plate 22 to rotate stably and uniformly with the second rotating rod 33 as the axis.

[0050] Furthermore, the spiral directions of the second spiral feed paddle 34 and the third spiral feed paddle 35 are opposite. The second spiral feed paddle 34 passes through the interior of the material passage 21. In the process of the second spiral feed paddle 34 transporting the mixed raw materials inside the mixing bin 3 into the interior of the mixing bin 2, the rotating third spiral feed paddle 35 will not affect the discharge of the mixed raw materials inside the mixing bin 2 from the discharge valve 28.

[0051] Furthermore, a first material guide funnel 26 is installed at the top of the outer side of the mixing bin 2 , and the output port of the first material guide funnel 26 is connected to the interior of the mixing bin 2 , so that the raw materials can be directly added to the interior of the mixing bin 2 through the first material guide funnel 26 .

[0052] Example 1, as Figure 1-2 and Figure 4-5 As shown, when the comb-shaped stirring plate 37 and the stirring blade 38 stir and mix the mixed raw materials inside the mixing bin 3, part of the raw materials are discharged into the mixing bin 3 through the second material guiding funnel 31, and because the second rotating rod 33 drives the second circular plate 36 to rotate, the raw materials inside the second material guiding funnel 31 can enter the mixing bin 3 only when the feed hole 39 coincides with the bottom of the second material guiding funnel 31, which can ensure that the raw materials inside the second material guiding funnel 31 are quantitatively entered into the mixing bin 3 each time, and then the stirring of the comb-shaped stirring plate 37 and the stirring blade 38 helps the raw materials added to the second material guiding funnel 31 to be quantitatively mixed with the mixed raw materials originally existing in the mixing bin 3, avoiding too much material added at one time, which makes it difficult for the raw materials to be quickly and evenly mixed with the original mixed raw materials, thereby helping to improve the efficiency and effect of the entire production equipment in producing anti-icing materials.

[0053] Example 2, as Figure 1-2 As shown, when the fastest stirring speed is not required to produce anti-icing materials, all the raw materials can be directly poured into the mixing chamber 2 through the first material guide funnel 26, and the solenoid valve 16 is closed to prevent the mixed raw materials in the mixing chamber 2 from entering the feed pipe 11 and the mixing chamber 3. Only the second servo motor 32 is controlled to drive the second rotating rod 33 to rotate, and the third spiral feed paddle 35 at the bottom end of the second rotating rod 33 is used to stir and mix the mixed raw materials in the mixing chamber 2. On the contrary, if the stirring efficiency of the entire equipment needs to be maximized, the two sets of solenoid valves 16 and the first servo motor 12 are directly opened. The first servo motor 12 drives the first spiral feed paddle 13 to rotate inside the feed pipe 11, allowing the mixed raw materials in the mixing chamber 2 to pass through the feed pipe 11 and the discharge port 14 and then enter the mixing chamber 3, and then return to the mixing chamber 2 through the feed pipe 21. In this way, the mixed raw materials continuously circulate in the mixing chamber 2, the feed pipe 11 and the mixing chamber 3, and cooperate with the stirring structure inside the mixing chamber 3 to ensure the stirring and mixing efficiency of the equipment for the mixed raw materials.

[0054] Working principle: Before use, the device is connected to the power supply. First, the anti-icing material raw materials are added to the mixing chamber 3 and the stirring chamber 2 through the second material guide funnel 31 and the first material guide funnel 26. Then the second servo motor 32 is controlled to drive the second rotating rod 33 to rotate counterclockwise, and the stirring blade 38 gradually pushes the raw materials inside the mixing chamber 3 into the material passing pipe 21, and then collects them into the interior of the stirring chamber 2, and the rotating third spiral feeding paddle 35 stirs the mixed raw materials inside the stirring chamber 2. At the same time, the control driving device 27 drives the first circular plate 22 to rotate clockwise, and the four groups of first rotating rods 242 rotate with the first circular plate 22. In the process, the anti-icing material mixed raw materials inside the stirring chamber 2 are stirred, and because the large gear 245 is fixed on the mounting ring 244, when the first rotating rod 242 rotates around the second rotating rod 33 as the center, the large gear 245 and the small gear 243 will drive the first rotating rod 242 to rotate, so that the first rotating rod 242 drives the outer sleeve 253 and The stirring rod 256 outside the outer sleeve 253 rotates together to stir the anti-icing material mixed raw materials inside the mixing chamber 2. At the same time, the first rotating rod 242 can also drive the annular chamber 251 to rotate outside the material passage 21. When the annular chamber 251 rotates, the connecting slider 254 moves along the path of the wavy chute 255 inside the wavy chute 255, which makes the annular chamber 251 continuously move back and forth during the rotation process, driving the outer sleeve 253 and the stirring rod 256 outside the outer sleeve 253 to continuously move up and down. During this process, the limiting slider 258 slides back and forth inside the limiting chute 257, and the limiting chute 257 is continuously stretched and then restored to its original length. At this time, the first rotating rod 242 also drives the outer sleeve 253 to rotate, and then the outer sleeve 253 and the stirring rod 256 also continuously move back and forth during the rotation process. After the mixed raw materials inside the mixing chamber 2 are completely stirred, the discharge valve 28 is opened to discharge all the mixed raw materials inside the mixing chamber 2.
