Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a defoaming device for building concrete pouring. Background Technique

[0002] During the concrete pouring process, due to factors such as vibration, stirring, and flow, a large number of bubbles will be generated. If these bubbles are not removed in time, it will cause voids and pores inside the concrete, affecting the compactness and strength of the concrete. In addition, the bubbles may also cause problems such as unevenness and cracking on the concrete surface.

[0003] Common defoaming methods include manual vibration and the use of defoamers. Manual vibration refers to vibrating the concrete by holding a mechanical vibrator to make the bubbles escape. It requires continuous vibration work by the operator, which is a labor-intensive task and may cause fatigue and discomfort to the operator's body; while the defoamer is a chemical substance that can reduce the surface tension of the concrete and prompt the bubbles to escape quickly. It may increase the total construction cost, and the defoamer may contain chemical components, which will have a certain negative impact on the environment during the use process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] An embodiment of the present utility model discloses a defoaming device for building concrete pouring.

[0031] The present utility model provides a defoaming device for building concrete pouring as shown in Figures 1-6 Figure 8. The defoaming device for building concrete pouring includes two symmetrically arranged support frames 1. The support frame 1 is in a vertical triangular shape, and the two support frames 1 are welded together through a connecting plate to form a stable "U" - shaped frame. A processing tank 2 for defoaming concrete is installed between the two support frames 1. A servo - motor 3 is fixedly installed at the bottom of the processing tank 2. The output shaft of the servo - motor 3 extends into the inner cavity of the processing tank 2, and a dynamic seal is provided at the connection between the output shaft of the servo - motor 3 and the processing tank 2 to prevent the concrete in the processing tank 2 from leaking from the bottom. A shaft rod 4 is fixedly installed on the output shaft of the servo - motor 3. Vertical chutes 5 are symmetrically formed on the outer wall of the shaft rod 4. Moving members 6 are slidably connected in the vertical chutes 5 respectively, and the moving member 6 is integrally in an "E" shape. A floating disk 7 is movably sleeved outside the shaft rod 4, and the top surface of the floating disk 7 is adhered to the bottom surfaces of the two moving members 6;

[0032] A horizontal rod 8 is integrally formed on the outer wall of the moving member 6. A number of extension rods are linearly arrayed at the bottom of the horizontal rod 8. A number of defoaming needles 9 for piercing the air bubbles in the concrete are installed on the outer walls of the extension rods. Factors such as the water - cement ratio of the concrete, the type and dosage of admixtures, the mixing time and mixing method may affect the size and quantity of air bubbles in the concrete. Different densities of defoaming needles 9 can be set by the cooperation of the horizontal rod 8 and the extension rod array, that is, horizontal rods 8 with different specifications can be set to adapt to different types and proportions of concrete.

[0033] The concrete to be defoamed is added into the processing tank 2. As the concrete continuously increases, the concrete pushes the floating disk 7 to move upward, and the floating disk 7 drives the two moving members 6 to move synchronously. After the addition is completed, the servo - motor 3 is started, so that the servo - motor 3 drives the two horizontal rods 8 to rotate horizontally. The air bubbles in the concrete are pierced and eliminated by the defoaming needles 9 on the outer walls of the horizontal rods 8, reducing the labor intensity and saving manpower, and avoiding environmental pollution; the moving member 6 can move up and down within a certain range in the vertical chute 5 according to the liquid level of the concrete, and can adapt to the defoaming of concrete with different pouring amounts.

[0034] To improve the practicability of the device, as shown in Figures 2-4As shown, two moving parts 6 are arranged oppositely, and through holes 10 are provided at the joint where they are in contact with each other. Bolts are threadedly connected in the through holes 10, and the ends of the bolts are fixed by nuts. When it is necessary to replace a certain horizontal rod 8, just unscrew the two nuts, take out the bolts in the through holes 10, and then the moving parts 6 can be removed to replace the horizontal rods 8 of different specifications.

[0035] A spiral bubble guiding part 11 is arranged at the bottom of the floating disk 7. The spiral bubble guiding part 11 is in an involute spiral shape, and the spiral angle is 0° to 30°. The outer wall of the spiral bubble guiding part 11 is fixedly installed on the outer wall of the shaft rod 4 through a connecting rod. The spiral bubble guiding part 11 is used to guide the bubbles dispersed in the concrete uniformly to its top center.

[0036] The bubbles in the freshly poured concrete are in an irregularly dispersed state. As the servo motor 3 drives the shaft rod 4 to rotate, under the connection action of the connecting rod, the spiral bubble guiding part 11 rotates accordingly. Under the guiding action of the spiral bubble guiding part 11, the bubbles in the concrete obtain sufficient kinetic energy and are guided to the top center of the spiral bubble guiding part 11, which is convenient for aggregation and being pricked and eliminated by the defoaming needles 9.

[0037] And in order to improve the functionality of the device, as Figure 1 and Figure 5 shown, the processing tank 2 includes a tank body and a tank cover hermetically installed on the top of the tank body. A feed inlet 12 is arranged on the top of the tank cover, and the feed inlet 12 is located at the edge of the tank cover. A transparent window is arranged on the outer wall of the tank body of the processing tank 2; the top of the support frame 1 is rotatably connected with a driving rod 13, and both ends of the driving rod 13 extend out of the side wall of the support frame 1. A runner 14 is connected to the end of the driving rod 13 far from the processing tank 2, and the end of the driving rod 13 close to the processing tank 2 is fixedly installed on the outer wall of the processing tank 2. By manually rotating the runner 14 on any side, the processing tank 2 rotates along the axis of the driving rod 13, and the concrete in the inner cavity of the processing tank 2 is poured out from the feed inlet 12.

[0038] Through the transparent window, the capacity of the concrete in the processing tank 2 can be observed in real time, and the defoaming degree of the concrete can also be observed, and the feeding time and discharging time of the processing tank 2 can be standardized; when the concrete defoaming is completed and needs to be poured out, the operator rotates the runner 14 on any side, so that one runner 14 drives the driving rod 13 to rotate, that is, the processing tank 2 rotates along the axis of the driving rod 13, and the other runner 14 and the driving rod 13 rotate synchronously. The concrete in the inner cavity of the processing tank 2 slowly pours out from the feed inlet 12.

[0039] Finally, in order to improve the stability of the device, as Figure 5 and Figure 6As shown, a mounting block 15 is bolted to the outer wall of the top of one side support frame 1. A plugging rod 16 is slidably connected inside the mounting block 15, and the plugging rod 16 is integrally in the shape of the Chinese character 'gan'. A reset member 17 is connected between the outer wall of the plugging rod 16 and the inner wall of the mounting block 15. The reset member 17 is not specifically limited. To conform to the actual situation, the reset member 17 can be a spring. Symmetrically arranged up and down on the outer wall of the driving rod 13 on this side are insertion holes 18, and the insertion holes 18 are adapted to the bottom end of the plugging rod 16.

[0040] In order to prevent the processing tank 2 from shaking due to external factors during the feeding or discharging process, when it is necessary to release the fixation of the whole processing tank 2, pull up the plugging rod 16 so that the bottom end of the plugging rod 16 disengages from one of the insertion holes 18 and stretch the reset member 17. As the processing tank 2 rotates, release the pulling force on the plugging rod 16. The bottom end of the plugging rod 16 abuts against the outer wall of the driving rod 13. When the processing tank 2 is completely flipped 180°, the bottom end of the plugging rod 16 automatically inserts into the other insertion hole 18 to re-complete the fixation of the whole processing tank 2.

[0041] In summary, the working principle of the present utility model is as follows: The concrete to be defoamed is added into the processing tank 2 through the feeding port 12. As the concrete continuously increases, the concrete pushes the floating disk 7 upward, and the floating disk 7 drives the two moving members 6 to move synchronously. After the addition is completed, start the servo motor 3 so that the servo motor 3 drives the two horizontal rods 8 to rotate horizontally. The defoaming needles 9 on the outer wall of the horizontal rods 8 pierce and eliminate the bubbles in the concrete. When it is necessary to complete the defoaming work of the concrete in the processing tank 2, turn off the servo motor 3 and the shaft rod 4 stops rotating. Pull up the plugging rod 16 so that the bottom end of the plugging rod 16 disengages from one of the insertion holes 18 and stretch the reset member 17. As the runner 14 drives the rotation of the processing tank 2, release the pulling force on the plugging rod 16. The bottom end of the plugging rod 16 abuts against the outer wall of the driving rod 13. The concrete in the processing tank 2 slowly pours out from the feeding port 12. As the processing tank 2 and the driving rod 13 continue to rotate, the bottom end of the plugging rod 16 automatically inserts into the other insertion hole 18.

[0042] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
