Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt processing technology, and more specifically, to an emulsified asphalt additive device. Background Technology
[0002] Asphalt is a viscous, black, and highly viscous liquid or semi-solid petroleum product. It is black in color and soluble in carbon disulfide and carbon tetrachloride. The main use of asphalt is in road construction. It is used as a glue or adhesive to mix with building aggregates to produce asphalt concrete. In highway construction projects, the use of asphalt is involved. In industrial asphalt manufacturing, emulsifiers are typically added to improve the processing quality.
[0003] There is a Chinese utility model patent with authorization announcement number CN220643713U5, which discloses a device for precise addition of emulsifier for modified emulsified asphalt. The device includes a box body with a box cover on the top. A circular through hole is opened on one side of the top of the box cover. A feeding cylinder is fixed to the top of the box cover corresponding to the circular through hole. An observation plate is fixed to the outside of the feeding cylinder. A connecting shaft is rotatably connected to the outside of the box cover corresponding to the circular through hole. A baffle is fixed to the surface of the connecting shaft corresponding to the circular through hole. The baffle has a circular cross-section and cooperates with the circular through hole. A handle is fixed to one end of the connecting shaft. A positioning mechanism is provided on the top of the box cover corresponding to the connecting shaft.
[0004] The aforementioned patent has the following problems: During material feeding, the amount of material added to the feeding cylinder still needs to be controlled manually by observing the observation plate; and when the heated asphalt and emulsifier enter the tank and are stirred by the stirring rod, the problem of asphalt and emulsifier clumping cannot be avoided. Therefore, an emulsified asphalt adding device is proposed to solve these problems. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an emulsified asphalt addition device. The technical problem to be solved by this utility model is that when feeding materials, it is still necessary to manually observe the observation plate to control the amount of material added to the feeding cylinder. When the heated asphalt and emulsifier enter the tank and are stirred by the stirring rod, it is still impossible to avoid the problem of asphalt and emulsifier clumping.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an emulsified asphalt addition device, comprising an outer cylinder assembly, wherein a stirring assembly is provided in the inner cavity of the outer cylinder assembly, and a feeding assembly is provided at the top of the outer cylinder assembly;
[0007] The feeding assembly includes a base block one, a stop block fixedly connected to one side of the base block one, side plates fixedly connected to both sides of the base block one, T-shaped grooves formed on the surface of each side plate, a stop bar fixedly connected to the side of each side plate away from the stop block, a base block two fixedly connected to the inner side of multiple stop bars, a telescopic cylinder fixedly connected to the top of the base block two, a feeding cylinder fixedly connected to the telescopic end of the telescopic cylinder, a base plate rotatably connected to the bottom of the feeding cylinder, and T-shaped sliders fixedly connected to both sides of the top of the feeding cylinder.
[0008] In a preferred embodiment, the outer cylinder assembly includes a mixing tank, a fixing ring is fixedly connected to the surface of the mixing tank, a discharge pipe is fixedly connected to the bottom of the mixing tank, a base frame is fixedly connected to the bottom of the fixing ring, an inlet is opened at the top of the mixing tank, a mixing port is opened at the top of the mixing tank, a feeding port is opened at the top of the mixing tank, a feeding pipe is sleeved on the surface of the inlet, and a high-pressure pump is fixedly connected to the end of the feeding pipe away from the inlet.
[0009] In a preferred embodiment, the stirring assembly includes a motor, a rotating column is fixedly connected to the bottom of the motor, a plurality of locking columns are fixedly connected to the surface of the rotating column, a stirring plate is fixedly connected to the inner cavity of each locking column, and a plurality of leakage holes are formed on the surface of each stirring plate.
[0010] In a preferred embodiment, each of the plurality of side plates is fixedly connected to a support frame, and each of the plurality of support frames is fixedly connected to a feed hopper. Each of the plurality of T-shaped sliders intersects with a T-shaped groove. The bottom of the feed hopper intersects with the top of the feeding cylinder. The surface of the bottom block away from the stop block is arc-shaped. The feeding cylinder is provided with multiple feeding cylinders of different inner diameters. During use, the multiple grooves limit the movement of the multiple T-shaped sliders, improving stability during sliding. The arc-shaped surface of the bottom block away from the stop block allows for slow rotation and opening / closing when the bottom of the chassis does not intersect with the bottom block. Before use, the feeding cylinder with different inner diameters can be selected based on the amount of emulsifier used. Because the inner diameters are different, the capacity inside the feeding cylinders is also different, thus eliminating the need for manual observation of the observation plate to control the amount of material added to the feeding cylinder.
[0011] In a preferred embodiment, one end of the high-pressure pump is fixedly connected to the feeding pipe, and the other end is connected to the outlet of the asphalt heating device. The fixing ring is fixedly connected to the base frame by multiple bolts, and a valve is installed inside the discharge pipe. In later use, the heated asphalt can be directly transported to the mixing tank through the high-pressure pump. After the mixing is completed, the valve of the discharge pipe can be opened directly to achieve the discharge effect.
[0012] In a preferred embodiment, the rotating column is fixedly connected to the motor output end, and the locking column is fixedly connected to the mixing plate by multiple bolts. The surface of the mixing plate has multiple perforations with different inner diameters. This allows for easier disassembly and assembly when the mixing plate is damaged or needs cleaning. During mixing, the multiple perforations with different inner diameters can filter out clumps of asphalt and emulsifier during mixing. The mixing plate and perforations can improve the mixing and liquefaction effects of the equipment by impacting and filtering the clumps of emulsifier and asphalt.
[0013] In a preferred embodiment, the rotating column intersects with the stirring port, and a connecting ring is fixedly connected to the bottom of the motor, with the bottom of the connecting ring fixedly connected to the top of the stirring port; this ensures the stability of the motor during operation, thus making the rotation of the rotating column and multiple stirring plates more stable.
[0014] In a preferred embodiment, the feeding assembly is fixedly connected to the top of the mixing tank, and there is a large space between the bottom block one and the bottom block two, which is perpendicular to the feeding port; later, when the feeding cylinder is in this position, after the bottom plate of the feeding cylinder is flipped, the emulsifier in the feeding cylinder can be discharged normally, which facilitates the emulsifier to enter the mixing tank through the feeding port and mix with the asphalt.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. This utility model features a feeding assembly. During use, multiple sliding grooves limit the movement of multiple T-shaped sliders, improving stability during sliding. The surface of the base block away from the stop block is arc-shaped, allowing for slow rotation and opening / closing when the base does not intersect with the base block. Before use, different inner diameter feeding cylinders can be selected based on the amount of emulsifier used. Since the inner diameter varies, the capacity of the feeding cylinder also differs, eliminating the need for manual observation of the feeding plate to control the feeding amount. This improves the quantitative control effect.
[0017] 2. This utility model, through its design, allows for the direct delivery of heated asphalt to the mixing tank via a high-pressure pump during later use. Starting the motor activates the mixing plate via a rotating column. During mixing, multiple perforations of varying inner diameters filter out clumps formed during the asphalt and emulsifier mixture. The mixing plate and perforations effectively agitate and filter out these clumps, improving both mixing and liquefaction efficiency. After mixing is complete, the discharge valve is opened for direct discharge, preventing the clumping problem that still occurs when heated asphalt and emulsifier are stirred by the mixing rod upon entering the tank. This significantly improves the mixing effect. Attached Figure Description

[0023] 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.
[0024] like Figures 1 to 4 As shown, this utility model provides an emulsified asphalt addition device, including an outer cylinder assembly 1, an inner cavity of the outer cylinder assembly 1 is provided with a stirring assembly 2, and a feeding assembly 3 is provided on the top of the outer cylinder assembly 1.
[0025] refer to Figure 2The outer cylinder assembly 1 includes a mixing tank 11. A fixing ring 12 is fixedly connected to the surface of the mixing tank 11. A discharge pipe 13 is fixedly connected to the bottom of the mixing tank 11. A base frame 14 is fixedly connected to the bottom of the fixing ring 12. An inlet 15, a mixing port 16, and a feeding port 17 are opened at the top of the mixing tank 11. A feeding pipe 18 is sleeved on the surface of the inlet 15. A high-pressure pump 19 is fixedly connected to one end of the feeding pipe 18 away from the inlet 15. One end of the high-pressure pump 19 is fixedly connected to the feeding pipe 18, and the other end is connected to the discharge port of the asphalt heating device. The fixing ring 12 and the base frame 14 are fixedly connected by multiple bolts. A valve is installed inside the discharge pipe 13. During later use, the heated asphalt can be directly transported into the mixing tank 11 through the high-pressure pump 19. After the mixing is completed, the valve of the discharge pipe 13 can be opened directly to achieve the discharge effect.
[0026] refer to Figures 2 to 3 The mixing assembly 2 includes a motor 21, with a rotating column 22 fixedly connected to the bottom of the motor 21. Multiple locking columns 23 are fixedly connected to the surface of the rotating column 22, and a mixing plate 24 is fixedly connected to the inner cavity of each locking column 23. Multiple perforations 25 are formed on the surface of each mixing plate 24. The rotating column 22 is fixedly connected to the output end of the motor 21, and the locking columns 23 are fixedly connected to the mixing plate 24 by multiple bolts. The multiple perforations 25 on the surface of the mixing plate 24 have different inner diameters. This allows for easier disassembly and assembly when the mixing plate 24 is damaged or needs cleaning. The mixing and liquefaction effects of the equipment can be improved by filtering the lumps formed when asphalt and emulsifier are mixed through multiple holes 25 with different inner diameters. The mixing plate 24 and the holes 25 can impact and filter the lumps of emulsifier and asphalt, thereby improving the mixing and liquefaction effects of the equipment. The rotating column 22 intersects with the mixing port 16, and a connecting ring is fixedly connected to the bottom of the motor 21. The bottom of the connecting ring is fixedly connected to the top of the mixing port 16. This ensures the stability of the motor 21 during operation, which in turn makes the rotation of the rotating column 22 and multiple mixing plates 24 more stable.
[0027] refer to Figures 2 to 4The feeding assembly 3 includes a base block 31, a stop block 32 fixedly connected to one side of the base block 31, and side plates 33 fixedly connected to both sides of the base block 31. T-shaped grooves 34 are formed on the surface of each side plate 33. A stop bar 35 is fixedly connected to the side of each side plate 33 away from the stop block 32. A base block 36 is fixedly connected to the inner side of the multiple stop bars 35. A telescopic cylinder 37 is fixedly connected to the top of the base block 36. A feeding cylinder 38 is fixedly connected to the telescopic end of the telescopic cylinder 37. A chassis 39 is rotatably connected to the bottom. T-shaped sliders 310 are fixedly connected to both sides of the top of the feeding cylinder 38. Supports 312 are fixedly connected to the top of multiple side plates 33.

The bottom of the feed hopper 311 intersects with the top of the feeding cylinder 38. The surface of the bottom block 31 away from the stop block 32 is arc-shaped. The feeding cylinder 38 is equipped with multiple feeding hoppers with different inner diameters. The feeding cylinder 38, during use, uses multiple T-shaped grooves 34 to limit the movement of multiple T-shaped sliders 310, improving the stability during sliding. The surface of the bottom block 31 away from the stop block 32 is arc-shaped, so that it can slowly rotate and open and close when the bottom of the chassis 39 does not intersect with the bottom block 31. Before use, the feeding cylinder 38 with different inner diameters can be selected according to the amount of emulsifier used. Since the inner diameter is different, the capacity of the feeding cylinder 38 is also different, so there is no need to manually observe the observation plate to control the amount of material added to the feeding cylinder 38. The feeding component 3 is fixedly connected to the top of the mixing tank 11. There is a large space between the bottom block 31 and the bottom block 36, and this space is perpendicular to the feeding port 17. Later, when the feeding cylinder 38 is in this position, after the chassis 39 at the bottom of the feeding cylinder 38 is flipped, the emulsifier in the feeding cylinder 38 can be discharged normally, which facilitates the emulsifier to enter the mixing tank 11 through the feeding port 17 to mix with the asphalt.
