Description

Technical Field

[0001] This utility model relates to the field of recycled powder mixing technology, and in particular to a cement-stabilized crushed stone mixing device with recycled powder. Background Technology

[0002] Recycled powder (mainly a byproduct of asphalt mixture production) can replace part of cement or mineral powder after pretreatment. Its composition needs to be partially matched with cement production raw materials (such as limestone and clay), and chemical analysis is used to ensure the stability of the clinker mineral composition after replacement.

[0003] When using recycled powder for mixing, the recycled powder is generated during the high-temperature production process of asphalt mixing plants, resulting in a high temperature during transport. The mixing of cement-stabilized crushed stone requires temperature control and cannot be directly mixed with cement and stabilized crushed stone. Therefore, the recycled powder needs to be cooled down before it can be used. However, natural cooling is time-consuming and results in low mixing efficiency of cement-stabilized crushed stone. Utility Model Content

[0004] This utility model provides a cement-stabilized crushed stone mixing device with recycled powder, which solves the above-mentioned structural technical problem that requires the recycled powder to be cooled before use, and that natural cooling causes a long waiting time, resulting in low mixing efficiency of cement-stabilized crushed stone.

[0005] The solution to the above-mentioned technical problems of this utility model is as follows: A cement-stabilized crushed stone mixing device with recycled powder includes a pre-stirring and cooling cylinder. A feed inlet is provided at the top of the pre-stirring and cooling cylinder. Stirring components are provided on opposite sides of the interior of the pre-stirring and cooling cylinder. A circular ring is provided on the outer wall of the pre-stirring and cooling cylinder. A circular ring rack is provided at the top of the circular ring. A circular ring-shaped groove is provided on the side of the top of the circular ring near the circular ring rack. A slider is slidably connected to the top of the circular ring-shaped groove. The top of the device is equipped with an inclined support, a fan device is installed on one side of the inclined support, and a speed-regulating motor is installed on the other side of the inclined support. The output shaft of the speed-regulating motor is equipped with a rotating rod, and a gear is installed on one side of the rotating rod. The bottom of the gear is connected to the top of the circular rack. The top of the circular body has multiple vertical plates arranged in a circular equidistant array. Each of the multiple vertical plates has a nozzle body on its top. A circular water tank is installed between the outer walls of the multiple nozzle bodies. A water conveying assembly is installed at the bottom of the circular water tank.

[0006] The beneficial effects of this utility model are as follows: the pre-stirring cooling cylinder facilitates the storage of aggregates and recycled powder for stirring; the feed inlet facilitates the pouring of materials; the stirring component continuously agitates the aggregates and recycled powder inside, thus utilizing the heat absorption capacity of the aggregates to reduce the temperature of the recycled powder; the first speed-regulating motor drives the gear on the rotating rod to rotate, allowing the gear to rotate on the ring rack, which in turn causes the inclined bracket on the ring-shaped groove and slider to rotate around the center of the ring rack, thereby allowing the fan device on the inclined bracket to continuously blow air to cool the interior of the pre-stirring cooling cylinder, accelerating the cooling speed of the recycled powder; the upright plate supports the nozzle body, which facilitates the spraying of water to cool the recycled powder inside the pre-stirring cooling cylinder; the water spraying needs to be sprayed according to certain specifications, and the water volume is controlled by professionals; the ring-shaped water tank can store water inside, and the water conveying component facilitates the delivery of external water to the interior of the ring-shaped water tank.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the agitation assembly includes two bearing bodies, which are disposed on opposite sides inside the pre-agitation cooling cylinder.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the bearing body can easily fix the rotating column, allowing the rotating column to rotate.

[0010] Furthermore, a rotating column is connected to one side of each of the bearing bodies, and a rotating block is provided at the center of the outer wall of the rotating column.

[0011] The beneficial effects of adopting the above-mentioned further scheme are: the rotating column can support the first rotating block and the second rotating block, the first rotating block can support the first stirring blade, and rotate the first stirring blade.

[0012] Furthermore, a first stirring blade is provided on both sides of the first rotating block, and two second rotating blocks are provided on the outer wall of the rotating column near both ends. Two second stirring blades are provided on both sides of the four second rotating blocks.

In this way, the middle area inside the pre-stirred cooling cylinder can be turned over, and the aggregate and recycled powder inside can be stirred, so that the heat absorption capacity of the aggregate can reduce the temperature of the recycled powder.

[0014] Furthermore, the water conveying assembly includes a conveying end, which is located at the bottom of the annular water tank. A conveying pipe is connected to the bottom of the conveying end, and a water pump is installed at the bottom of the conveying pipe.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the conveying end can be connected to a conveying pipe, which allows the water flow inside the pipe connected to the water pump to be conveyed to the inside of the circular water storage tank.

[0016] Furthermore, a funnel is provided at the bottom of the pre-stirring cooling cylinder, and an auger feeding device is provided at the bottom of the funnel. A twin-shaft forced mixer is connected to one side of the auger feeding device.

[0018] Beneficial effects: The pre-stirring cooling cylinder allows the aggregate and recycled powder to be mixed by the stirring components, which reduces the temperature of the recycled powder due to the heat absorption capacity of the aggregate. Then, the fan device blows air into the interior of the pre-stirring cooling cylinder to cool it down. The water supply component allows the nozzles to spray water for cooling, which can accelerate the cooling efficiency of the recycled powder, save time as much as possible, and improve the mixing efficiency of cement-stabilized crushed stone.

[0034] Example 2

[0035] like Figure 1-8 As shown, the stirring assembly 3 includes two bearing bodies 31, which are located on opposite sides inside the pre-stirring and cooling cylinder 1. Each bearing body 31 is connected to a rotating column 32 on its opposite side. A first rotating block 33 is provided at the center of the outer wall of the rotating column 32. A first stirring blade 34 is provided on both sides of the first rotating block 33. Two second rotating blocks 35 are provided near both ends of the outer wall of the rotating column 32.

[0037] Example 3

[0038] like Figure 1-8As shown, the water conveying assembly 16 includes a conveying end 161, which is located at the bottom of the annular water tank 15. The bottom of the conveying end 161 is connected to a conveying pipe 162, and a water pump 163 is installed at the bottom of the conveying pipe 162. A funnel 17 is installed at the bottom of the pre-stirring and cooling cylinder 1, and an auger feeding device 18 is installed at the bottom of the funnel 17. A twin-shaft forced mixer 19 is connected to one side of the auger feeding device 18.

[0039] In this embodiment, the conveying end 161 can be connected to the conveying pipe 162, which allows the water inside the pipe connected to the water pump 163 to be conveyed to the inside of the annular water tank 15. The funnel 17 facilitates the entry of aggregates and recycled powder into the auger feeding device 18. The auger feeding device 18 can be used to transfer aggregates and recycled powder to the inside of the twin-shaft forced mixer 19 for mixing, which then facilitates the subsequent addition of cement-stabilized crushed stone for mixing together.

[0040] Working principle:

[0041] When cooling of the recycled powder is required, the conveying device first transports the aggregate and recycled powder into the pre-stirring cooling cylinder 1. The powder is then poured into the pre-stirring cooling cylinder 1 through the feed inlet 2. The second speed-regulating motor 37 is started first, causing the first rotating block 33 and the second rotating block 35 on the rotating column 32 to rotate. This causes the first stirring blade 34 and the second stirring blade 36 to rotate together, continuously agitating the aggregate and recycled powder inside the pre-stirring cooling cylinder 1, ensuring constant contact between them. The heat absorption capacity of the aggregate lowers the temperature of the recycled powder. When air cooling is required, the first speed-regulating motor 10 drives the rotating rod 11 and gear 12 to rotate and mesh with the annular rack 5. The annular groove 6 allows the inclined support 8 on the slider 7 to move circumferentially. The first speed-regulating motor on the inclined support 8... 10. The inclined support 8 can rotate around the center of the ring rack 5, which allows the fan device 9 on the inclined support 8 to continuously blow air into the interior of the pre-stirring cooling cylinder 1 to cool it down, thus accelerating the cooling speed of the recycled powder. When water cooling is required, water should be sprayed in a timely and quantitative manner according to the requirements of professionals. First, the water pump 163 is connected to the external water pipe, and the water is transported to the conveying pipe 162. The water is then transported to the interior of the ring water tank 15 through the ring water tank 15. The water can then be transported to the interior of the nozzle body 14 through the nozzle body 14. This allows the water to be sprayed into the interior of the pre-stirring cooling cylinder 1, accelerating the cooling speed of the recycled powder and saving time as much as possible. This improves the mixing efficiency of cement-stabilized crushed stone. The cooled recycled powder and aggregate can then be transported to the interior of the twin-shaft forced mixer 19 for mixing through the auger feeding device 18.
