Description

Technical Field

[0001] This utility model relates to the field of cement foaming technology, specifically to a cement foaming device. Background Technology

[0002] Foamed cement, also known as foamed concrete or lightweight concrete, is a lightweight microporous concrete material made by preparing foaming agents into foam using physical or chemical methods, then adding the foam to a slurry made of cement, aggregates, admixtures, additives, and water. After mixing, pouring, and curing, it possesses advantages such as lightweight, thermal insulation, sound insulation, fire resistance, and vibration damping. In the processing of foamed cement, a cement foaming device is generally used to mix the foam and cement together. If the mixing time is too short, the foam and cement are not fully mixed, easily forming foam clumps, leading to cavities in the solidified cement and affecting the building quality. Conversely, if the mixing time is too long, the foam is prone to defoaming, affecting the density and quality of the foamed cement, resulting in poorer thermal insulation, sound insulation, and vibration damping effects. Therefore, a cement foaming device is provided. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides an embodiment of a cement foaming device, comprising a frame 1, a foaming tank 3 installed at the top of one side of the frame 1, an mounting plate 5 installed at the top of the foaming tank 3, a gearbox 6 installed at the top of the mounting plate 5, a drive motor 7 installed at the top of the gearbox 6, two sets of stirring rods 16 installed at the bottom of the gearbox 6, blades 17 installed on the outer side of the stirring rods 16, a main gear 18 installed inside the gearbox 6, the main gear 18 being located at the center of the gearbox 6, the gearbox 6 being fixedly connected to the output shaft of the drive motor 7, driven gears 19 being movably connected to both sides of the main gear 18, and the driven gears 19 being fixedly connected to the top of the stirring rods 16, and several sets of blades 17 being provided, the blades 17 being evenly distributed on both sides of the stirring rods 16, which improves the mixing effect, shortens the mixing time, and avoids foam defoaming.

[0025] Specifically, as shown in the figure, during use, the foaming agent can be quickly and fully foamed through the foaming tube 8 and delivered into the foaming tank 3. The operation of the drive motor 7 will drive the main gear 18, drive the two sets of driven gears 19, control the two sets of stirring rods 16 to rotate synchronously, and drive the blades 17 to quickly stir and mix the cement and foam.

[0026] A feed hopper 4 is installed at the top of one side of the foaming tank 3, and a discharge valve 2 is installed at the bottom of one side of the foaming tank 3. A control box 15 is installed inside the frame 1. An air compressor 9 is installed at the top of the other side of the frame 1, and a pump 10 is installed at the bottom of the air compressor 9. A liquid storage tank 13 is installed at the bottom of the pump 10, and a water suction pipe 12 is installed at the bottom of the pump 10. A foaming pipe 8 is installed at the top of the other side of the foaming tank 3. The foaming pipe 8 includes a straight pipe 801, and an inlet 803 is installed on one side of the straight pipe 801. A pipe is installed between the inlet 803 and the output end of the pump 10. A check valve 802 is installed at the bottom of the straight pipe 801, and a pipe is installed between the check valve 802 and the output end of the air compressor 9.

[0027] Specifically, as shown in the figure, during use, the foaming agent inside the storage tank 13 is delivered to the inside of the straight pipe 801 by the operation of the pump 10, and the operation of the air compressor 9 will deliver gas to the inside of the straight pipe 801, using air pressure to quickly and fully foam.

[0028] A handrail 11 is installed on one side of the frame 1, and casters 14 are installed at the four corners at the bottom of the frame 1. The handrail 11 makes it easy for people to grab and apply force, and the four sets of casters 14 make it easy to push the cement foaming device to slide and transfer it to the target area.

[0029] Working principle: In use, first, transport the cement foaming device to the target area and connect it to an external power source. Introduce the foaming agent into the storage tank 13, then pour cement and water into the foaming tank 3. Operate the control box 15 to control the drive motor 7, which drives the main gear 18, which in turn drives two sets of driven gears 19, controlling the two sets of stirring rods 16 to rotate synchronously. This drives the blades 17 to rapidly stir the cement. Subsequently, operate the control box 15 to control the air compressor 9 and pump 10 to operate, discharging the foaming agent from the storage tank 13. The air is delivered into the straight pipe 801, and the operation of the air compressor 9 will deliver the gas into the straight pipe 801. The air pressure is used to quickly and fully foam the cement. The foam is delivered into the foaming tank 3. Under the rotation of the stirring rod 16, the cement and foam are quickly stirred and mixed. The setting of two sets of stirring rods 16 improves the mixing effect, shortens the mixing time, and avoids the foam defoaming phenomenon. After the mixing is completed, the control device stops operating and opens the discharge valve 2 to discharge the cement, thus completing the use of the cement foaming device.
