Description

Technical Field

[0001] The utility model relates to the technical field of asphalt foaming, in particular to an asphalt foaming device. Background Technique

[0002] During the foaming process of asphalt, the heated asphalt needs to be placed in a mixing chamber to be mixed and foamed with air and water. The water inlet on the existing foaming device is usually fixed. When water enters through the water inlet, the water continuously flows down to the same part of the asphalt, resulting in more contact between the asphalt at this part and water, so that this part of the asphalt foams significantly. However, the asphalt in other parts cannot come into large-area contact with water. Therefore, the foaming effect is not good, which easily leads to the problem of uneven asphalt foaming and affects the actual use effect of asphalt.

[0003] In view of the above problems, the inventor proposed an asphalt foaming device to solve the above problems. Summary of the Utility Model

[0004] In order to solve the problem of uneven asphalt foaming; the purpose of the utility model is to provide an asphalt foaming device.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: It includes a foaming barrel and support legs arranged at the bottom of the foaming barrel. A motor is fixedly connected to the top of the foaming barrel. The motor is a servo motor and is electrically connected to an external power supply and is controlled by a control switch. One end of the output shaft of the motor penetrates through the foaming barrel and is fixedly connected to a rotating rod. One end of the rotating rod is fixedly connected to an auger. Stirring frames are fixedly connected to the outer surface of the rotating rod. A feeding pipe is communicated with the bottom of the foaming barrel, and a feeding pipe is communicated with the top of the foaming barrel. Through the arrangement of the auger, the asphalt at the bottom is conveyed to the top. Due to gravity, the asphalt at the top descends to the bottom, so that the asphalt at the top can come into better contact with water, so that the asphalt foams more evenly, and further improves the foaming effect of the device. A drain pipe is communicated with the bottom of the outer surface of the foaming barrel. A sealing cover is arranged at one end of the feeding pipe. The drain pipe is used to discharge waste water.

[0006] Preferably, a filter funnel is fixedly connected to the bottom of the inner surface of the foaming barrel. A water storage tank is sleeved and fixedly connected to the outer surface of the rotating rod and above the stirring frame. The filter funnel is used to filter water, and at the same time, the funnel shape enables the asphalt to descend better and gather at the auger. An opening is provided at the top of the water storage tank, and a water pump is fixedly connected to the top of the foaming barrel. The opening provides space for the water outlet pipe. The water outlet end of the water pump is communicated with a water outlet pipe. A sealing rubber plate is sleeved and rotatably connected to the outer surface of the rotating rod. The sealing rubber plate is used to seal the opening to ensure the normal operation of the device. One end of the water outlet pipe sequentially penetrates through the foaming barrel and the sealing rubber plate and extends into the interior of the water storage tank. The bottom of the sealing rubber plate is in close contact with the top of the water storage tank. The water outlet pipe supplies water to the water storage tank. The water storage tank is used to install the nozzles. The water inlet end of the water pump is communicated with a water inlet pipe. One end of the water inlet pipe penetrates through the foaming barrel and extends into the interior of the foaming barrel. One end of the water inlet pipe is located between the foaming barrel and the filter funnel. The water inlet pipe is used to pump out the water between the foaming barrel and the filter funnel. Nozzles are provided at the bottom of the water storage tank. The number of nozzles is several. The nozzles are used to spray water.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0008] 1. Through the setting of the auger, the asphalt at the bottom is conveyed to the top. Due to gravity, the asphalt at the top descends to the bottom, so that the asphalt at the top can better contact with water, making the asphalt foam more evenly, and thus increasing the foaming effect of the device;

[0009] 2. Through the setting of the water pump, the accumulated water at the bottom is conveyed into the water storage tank and sprayed out through the nozzles to water the asphalt at the top. The water at the bottom can not only be recycled, saving a certain amount of water resources, but also keep the water flowing, enabling the water to better contact with the asphalt and increasing the foaming effect of the asphalt.

[0024] By adopting the above technical solution, the sealing rubber plate 14 is used to seal the opening 11 to ensure the normal operation of the device.

[0025] One end of the water outlet pipe 13 sequentially penetrates through the foaming barrel 1 and the sealing rubber plate 14 and extends into the interior of the water storage tank 10, and the bottom of the sealing rubber plate 14 is in close contact with the top of the water storage tank 10.

[0032] By adopting the above technical solution, the drain pipe 17 is used to discharge the waste water.

[0033] Working principle: Asphalt is added through the feeding pipe 8. Due to gravity, the asphalt sinks to the bottom. Water is added into the foaming barrel 1 through the feeding pipe 8. The motor 3 is started to drive the rotating rod 4 to make the auger 5 rotate. The rotation of the auger 5 conveys the asphalt at the bottom to the top. Due to gravity, the asphalt at the top drops to the bottom, so that the asphalt contacts the water evenly. At the same time, the rotating rod 4 drives the stirring frame 6 to rotate to stir the asphalt, making the contact between the asphalt and the water more uniform. Due to the setting of the filter mesh hopper 9, the asphalt is stored in the filter mesh hopper 9, and the water flows to the space between the foaming barrel 1 and the filter mesh hopper 9. The water pump 12 is started to pump the water between the foaming barrel 1 and the filter mesh hopper 9 into the water storage tank 10 through the water inlet pipe 15 and the water outlet pipe 13. The water in the water storage tank 10 is sprayed out through the nozzle 16 to spray the asphalt at the top. At the same time, the water flow circulates and contacts the asphalt more evenly. While the rotating rod 4 drives the auger 5 to rotate, the rotating rod 4 drives the water storage tank 10 to rotate, and the water storage tank 10 drives the nozzle 16 to rotate, making the water spray more evenly onto the asphalt. After foaming is completed, the waste water is discharged through the drain pipe 17. The sealing cover 18 is opened to make the asphalt flow out through the blanking pipe 7.
