Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixing, in particular to a natural rock asphalt mixture stirring device. Background Art

[0002] Asphalt mix is a material used in road construction that primarily consists of asphalt and aggregates such as crushed stone, sand, and fly ash.

[0003] There are roughly several types of asphalt, including hot mix asphalt mixture, cold mix asphalt mixture and modified asphalt mixture, etc., which are basically mixed and processed with asphalt liquid as raw material.

[0004] During the processing, in the conventional processing method, the introduction of asphalt is basically direct pouring through the pipeline. In this way, the asphalt will accumulate on one side of the mixing chamber before mixing, and will come into contact with part of the material more fully. The disadvantage is that the other part of the material does not come into contact with the asphalt thoroughly, so it needs to be mixed and stirred evenly. However, due to the above-mentioned asphalt pouring method, the mixing effect is not good enough during mixing, resulting in the mixed material requiring a longer stirring time to meet the requirements. Based on this, the present application provides a natural rock asphalt mixture stirring device. Utility Model Content

[0009] An asphalt conduit is provided inside the mixing chamber, and one end of the asphalt conduit extends to one end of the mixing chamber.

[0010] As a further improvement of the present invention, a material outlet is provided at the bottom of one side of the mixing chamber for discharging the mixed material.

[0013] As a further improvement of the present invention, the asphalt conduit includes a pipeline, and a guide plate is provided on the top of the pipeline. The guide plate is arranged in an arc shape with a preset angle and is used to protect the top of the pipeline.

[0014] As a further improvement of the present invention, the bottom of the pipeline is provided with liquid outlets arranged in an equidistant linear array for spraying asphalt liquid.

[0034] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 Asphalt mixture is a material used in road construction. Its types are roughly divided into several types, including hot mix asphalt mixture, cold mix asphalt mixture and modified asphalt mixture, etc. Basically, they are mixed and processed with asphalt liquid as raw material.

[0035] During the processing, due to the asphalt pouring method, the mixing effect is not good enough, resulting in the mixed material requiring a longer stirring time to meet the requirements. Based on this, the present application provides a natural rock asphalt mixture stirring device, including a feed hopper 1 for mixing materials and a mixing assembly 3 for mixing;

[0036] The mixing assembly 3 includes a mixing chamber 32, a support plate 36 is provided on the top of the mixing chamber 32, and the top of the support plate 36 is combined with the feed hopper 1;

[0037] Two mixing augers 37 are installed inside the mixing chamber 32 and are arranged to rotate in opposite directions. A drive motor 35 is provided on one side of the mixing chamber 32. The output shaft of the drive motor 35 is connected to the mixing augers 37 through a transmission member.

[0038] An asphalt conduit 2 is provided inside the mixing chamber 32 , and one end of the asphalt conduit 2 extends to one end of the mixing chamber 32 .

[0039] The mixing chamber 32 is used to contain and mix natural rock asphalt and its aggregate.

[0040] The feed hopper 1 is used to feed aggregate or other additives into the mixing chamber 32 and is located at the top of the mixing chamber 32 to ensure smooth and stable feeding.

[0041] The support plate 36 is located at the top of the mixing chamber 32 to ensure the stable connection of the feed hopper 1 and the stability of the overall structure.

[0042] Two mixing augers 37 rotate in opposite directions in the mixing chamber 32 to stir and evenly mix the aggregate and asphalt. The design of the augers makes the mixing more uniform and prevents local insufficient mixing.

[0043] The driving motor 35 is installed on one side of the mixing chamber 32 and is connected to the mixing auger 37 through an output shaft and a transmission member, providing power to drive the auger to rotate and achieve the stirring function.

[0044] The asphalt conduit 2 is provided in the mixing chamber 32 for conveying the asphalt from the storage container to the mixing chamber 32. One end of the conduit extends into the bottom of the mixing chamber 32 so that the asphalt can be evenly distributed in the mixture.

[0045] How it works

[0046] First, the aggregate enters the mixing chamber 32 through the feed hopper 1 and is connected to the support plate 36 to ensure stable feeding.

[0047] At this time, after the drive motor 35 is started, it drives two counter-rotating mixing augers 37 through the transmission member to mix. The mixing augers 37 continuously turn and stir the aggregate in the mixing chamber 32, increasing the contact area between the aggregate and the asphalt and improving the mixing uniformity.

[0048] When the asphalt is transported to the mixing chamber 32 through the asphalt conduit 2, the conduit is designed to be sprayed at multiple angles to ensure that the asphalt is evenly distributed in the aggregate.

[0049] The combination of the mixing auger 37 and the asphalt conduit 2 ensures sufficient contact between the asphalt and the aggregate, thereby achieving uniform mixing.

[0050] The design of the counter-rotating mixing auger 37 and the multi-directional injection asphalt conduit 2 ensures that the asphalt is evenly distributed in the mixing chamber 32, avoiding the uneven mixing phenomenon under the traditional pouring method.

[0051] Due to the multi-directional injection of asphalt and the continuous stirring of the auger, the time required for mixing is reduced and production efficiency is improved.

[0052] The injection device can accurately control the amount of asphalt injected, thus avoiding excessive or insufficient asphalt addition, improving mixing quality and reducing material waste.

[0053] Overall production costs are reduced due to improved mixing efficiency and precise control of asphalt dosage.

[0054] Traditional mixing methods may lead to uneven distribution of asphalt during the mixing process. The new device improves the stability and reliability of the mixing process by improving the mixing method.

[0055] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 A material outlet 33 is provided at the bottom of one side of the mixing chamber 32 for discharging the mixed material.

[0056] A support frame 31 is provided at the bottom of the mixing chamber 32 , a base 34 is provided at the bottom of the support frame 31 , and a driving motor 35 is assembled at the top of the base 34 .

[0057] A group of spraying areas 38 are arranged at equal intervals on both sides of the inner wall of the mixing chamber 32 , and the spraying areas 38 are connected to the asphalt conduit 2 .

[0058] The material outlet 33 is provided at the bottom of one side of the mixing chamber 32 for discharging the mixed material (i.e. the mixed asphalt mixture). The design of the material outlet 33 ensures that the mixed material can be discharged smoothly, avoiding material accumulation or blockage.

[0059] A support frame 31 is provided at the bottom of the mixing chamber 32 to support the structure of the entire mixing chamber 32. The bottom of the support frame 31 is connected to a base 34, and the top of the base 34 is combined with a drive motor 35 to provide stable support and driving force for the mixing chamber 32.

[0060] A group of equidistant spraying areas 38 are provided on both sides of the inner wall of the mixing chamber 32 . These spraying areas 38 are connected to the asphalt conduit 2 and are used to spray asphalt at multiple angles and directions during the mixing process to ensure that the asphalt can be evenly distributed in the mixing chamber 32 .

[0061] How it works

[0062] The mixed material is discharged through the material outlet 33. The material outlet 33 is usually designed to be adjustable or have a valve structure to control the discharge speed and amount of the material. The support frame 31 and the base 34 provide solid support for the mixing chamber 32. The drive motor 35 on the base 34 transmits power to the mixing auger 37 through the support frame 31 to ensure the stable operation of the mixing device. The spray areas 38 on both sides of the inner wall are connected to the asphalt conduit 2. The spray areas 38 evenly spray asphalt into the mixing chamber 32, ensuring that the asphalt can contact the aggregate from multiple directions, further improving the mixing uniformity. The drive motor 35 drives the mixing auger 37 to rotate, and the auger fully stirs the aggregate and asphalt in the mixing chamber 32, so that the asphalt and aggregate are thoroughly mixed.

[0063] The setting of the spraying area 38 ensures that the asphalt can be sprayed into the mixing chamber 32 from multiple directions. The multi-angle spraying method can effectively increase the contact area between the asphalt and the aggregate, thereby making the mixing more uniform.

[0064] The material outlet 33 is provided to facilitate the smooth discharge of the mixed material, thereby reducing the retention of the material in the mixing chamber 32 and improving production efficiency.

[0065] The design of the support frame 31 and the base 34 enhances the stability of the mixing chamber 32, ensuring reliability and durability during the mixing process. The drive motor 35 is stably supported by the base 34, making the mixing device more stable during operation.

[0066] The coordinated use of the spraying area 38 and the mixing auger 37 allows the asphalt and aggregate to be mixed more fully and evenly, thereby improving the mixing efficiency and shortening the mixing time.

[0067] The setting of the spraying area 38 makes the spraying of asphalt more precise, can control the amount of asphalt mixed each time, avoids the problem of excess or insufficient asphalt, and improves the mixing quality.

[0068] See also Figure 3 、 Figure 4 、 Figure 5 The asphalt conduit 2 includes a pipe 22 , and a guide plate 21 is provided on the top of the pipe 22 . The guide plate 21 is arranged in an arc shape at a preset angle and is used to protect the top of the pipe 22 .

[0069] Liquid outlets 23 are provided at the bottom of the pipe 22 and are arranged in a linear array at equal distances for spraying asphalt liquid.

[0070] The pipeline 22 is the main part of the asphalt transportation, which is responsible for transporting the asphalt from the storage to the mixing chamber 32. The pipeline 22 is designed with sufficient strength and corrosion resistance to ensure long-term stable asphalt transportation.

[0071] The guide plate 21 is installed on the top of the pipe 22 and is arranged in an arc shape with a preset angle. This guide plate 21 serves to protect the top of the pipe 22 from external damage;

[0072] The liquid outlets 23 located at the bottom of the pipe 22 are arranged in an equidistant linear array, which means that the distance between each liquid outlet 23 is fixed, ensuring that the asphalt can be sprayed out evenly from each liquid outlet 23. The design of the liquid outlet 23 also takes into account flow control and spraying range to ensure that the asphalt can accurately cover the aggregate in the mixing chamber 32.

[0073] Working principle:

[0074] When asphalt is transported through the pipeline 22, the asphalt flows to the bottom of the pipeline 22 and is evenly sprayed into the mixing chamber 32 through the liquid outlets 23 arranged in an equidistant linear array, ensuring that the asphalt can be evenly and stably covered on the aggregate and fully mixed with the aggregate.

[0075] Summary of beneficial effects

[0076] The provision of the guide plate 21 effectively protects the top of the pipeline 22 from external damage, prolongs the service life of the pipeline 22, and reduces the cost of maintenance and replacement.

[0077] The equidistant and linear arrangement of the liquid outlets 23 ensures that the asphalt can be evenly sprayed out from each liquid outlet 23 and covered on the aggregate in the mixing chamber 32. This uniform spraying improves the mixing uniformity of the asphalt and aggregate, thereby improving the quality of the mixture.

[0078] The design of the liquid outlet 23 takes flow control into account, so that the amount of asphalt sprayed can be adjusted as needed. This flexibility allows the device to adapt to different mixing ratios and production needs.

[0079] The asphalt spraying method and flow path improve the mixing efficiency of asphalt and aggregate. The asphalt can contact and mix with the aggregate more quickly, thus shortening the mixing time and improving production efficiency.

[0080] The provision of the guide plate 21 and the liquid outlet 23 enhances the structural stability of the entire asphalt conduit 2 , and this stability ensures the reliability and safety of the asphalt during transportation and spraying.

[0081] See also Figure 1 、 Figure 6 as well as Figure 7 The feed hopper 1 is combined with the support plate 36 on the mixing assembly 3 through fasteners. The feed hopper 1 includes a main body 11, a discharge port is provided below the main body 11, and a feed port 12 is provided above the main body 11. The discharge port is communicated with the mixing chamber 32.

[0082] A baffle 13 is provided at the bottom of the body 11 and inside the discharge port. The top of the baffle 13 is arranged in an arc shape to guide the introduction of materials.

[0083] The feed hopper 1 body 11 is used to accommodate and introduce aggregates. The feed hopper 1 is fixed to the support plate 36 on the mixing assembly 3 by fasteners, ensuring its stability and position accuracy.

[0084] The feed opening 12 is located above the feed hopper 1 body 11 and is used to feed aggregate or other additives into the feed hopper 1. The feed opening 12 is usually designed to be wide so that the aggregate can be poured into the feed hopper 1 quickly and conveniently.

[0085] The discharge port is located below the main body 11 of the feed hopper 1 and communicates with the mixing chamber 32. The discharge port is designed to fit closely with the mixing chamber 32 to ensure that the aggregate can smoothly enter the mixing chamber 32 for mixing.

[0086] The baffle 13 is arranged on the inner side of the discharge port at the bottom of the body 11. The top of the baffle 13 is in an arc shape, which is used to guide the material into the mixing chamber 32. The design of the baffle 13 can help the aggregate flow into the discharge port more evenly, reducing the blockage and accumulation of materials.

[0087] Working principle:

[0088] First, the aggregate is poured into the feed hopper 1 through the feed port 12. The design of the feed port 12 facilitates rapid and efficient filling of the material.

[0089] Aggregate falls in the feed hopper 1 and encounters the baffle 13 at the bottom. The arc shape of the baffle 13 helps guide the aggregate to flow evenly toward the discharge port, preventing the material from being accumulated or blocked at the discharge port.

[0090] Aggregate enters the mixing chamber 32 through the discharge port and is mixed with asphalt. The design of the discharge port ensures smooth discharge of the material and ensures that the aggregate can effectively enter the mixing chamber 32 for mixing.

[0091] The feed hopper 1 is fastened to the support plate 36 on the mixing assembly 3 by fasteners, thereby ensuring the stability of the feed hopper 1 and avoiding possible displacement or vibration during operation.

[0092] The wide feed port 12 is designed to facilitate the rapid pouring of aggregates, thereby improving the convenience of operation and work efficiency.

[0093] The arc design of the baffle 13 effectively guides the aggregate to flow into the discharge port, reduces the accumulation and blockage of the material in the feed hopper 1, and ensures the smooth discharge of the material.

[0094] The arc shape of the baffle 13 helps to evenly guide the material into the mixing chamber 32, reducing the risk of blockage at the discharge port and improving production stability.

[0095] By ensuring that aggregates can smoothly enter the mixing chamber 32, the design of the feed hopper 1 improves mixing efficiency and ensures uniform mixing of aggregates and asphalt, thereby optimizing the quality of the final mixture.
