Description

TECHNICAL FIELD

[0001] The utility model relates to a defoaming device field, concretely relates to a nozzle structure for defoaming device. BACKGROUND

[0002] When the thickener works, a defoaming device needs to be arranged on the top of the thickener to remove the bubbles. The existing defoaming device, such as the utility model patent with the application number CN202021587354.8, discloses a thickener defoaming device, which comprises a defoaming pipe. The defoaming pipe is annular, and the defoaming pipe is provided with a plurality of spray heads distributed along the circumference of the defoaming pipe. The defoaming water is delivered to each spray head through the defoaming pipe, and any spray head sprays defoaming water towards the center of the thickener to eliminate the foam.

[0003] However, the spray head angle of the existing defoaming device is fixed and cannot be adjusted, which limits the range of defoaming agent sprayed by the spray head, so that the bubbles cannot be efficiently eliminated, and improvement is needed. UTILITY MODEL CONTENT

[0010] As a further improvement, the mounting seat is provided with a slide driven by a power device and moving along the radial direction of the annular main pipeline, and the motor is bolted to the slide.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1. The motor drives the rotating disc to rotate, the rotating disc drives the defoaming branch pipe to reciprocate in the horizontal plane through the first pin shaft, the connecting rod and the second pin shaft, the defoaming branch pipe drives the nozzle to reciprocate, thereby increasing the range of the nozzle spraying the defoaming agent and improving the defoaming efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1:

[0026] like Figures 1 to 4 As shown, a nozzle structure for a defoaming device includes an annular main pipe 1, an inlet pipe 2 on the annular main pipe 1, and a defoaming agent supply mechanism connected to the inlet pipe 2. Multiple outlets 3 are evenly spaced circumferentially on the inner side of the annular main pipe 1. Each outlet 3 is connected to one end of a defoaming branch pipe 5 via a corrugated pipe 4, and a nozzle 6 is fixedly installed at the other end of the defoaming branch pipe 5.

[0027] The annular main pipe 1 is fixedly installed with mounting seats 7 corresponding to the defoaming branch pipes 5. The mounting seats 7 specifically include an upper mounting seat 8 and a lower mounting seat 9. An arc-shaped hole matching the outer wall of the annular main pipe 1 is provided between the upper mounting seat 8 and the lower mounting seat 9. The upper mounting seat 8 and the lower mounting seat 9 are fixedly connected by bolts. The upper mounting seat 8 and the lower mounting seat 9 hold the outer wall of the annular main pipe 1 tightly to prevent the mounting seats 7 from sliding along the annular main pipe 1.

[0028] The lower end of the upper mounting base 8 is integrally formed with an inner mounting plate 10 and an outer mounting plate 11 on the inner and outer sides of the annular main pipe 1, respectively. A vertically extending mounting shaft 12 is welded to the bottom of the defoaming branch pipe 5 near the corrugated pipe 4. The mounting shaft 12 is rotatably mounted on the corresponding inner mounting plate 10 via bearings. A motor 13 is mounted on the top of the outer mounting plate 11. In this embodiment, the motor 13 is bolted to the outer mounting plate 11, thus fixing the position of the motor 13. A coaxially arranged... Turntable 14 has a vertically extending axis. A first pin 15 is eccentrically set at the top of turntable 14. A second pin 16 is welded to the top of the end of defoaming branch pipe 5 away from corrugated pipe 4. Both the first pin 15 and the second pin 16 extend vertically. A connecting rod 17 is hinged between the first pin 15 and the second pin 16. When turntable 14 rotates, it drives defoaming branch pipe 5 to swing back and forth in the horizontal plane through connecting rod 17. Defoaming branch pipe 5 drives nozzle 6 to swing back and forth, thereby increasing the range of defoamer sprayed by nozzle 6 and improving defoaming efficiency.

[0029] In this embodiment, the defoaming branch pipe 5 is horizontally arranged, and its radius does not coincide with that of the annular main pipe 1. The annular main pipe 1 is fixedly installed on the top of the thickener and coaxially arranged with the thickener. An inclined pipe 18 is welded to the end of the defoaming branch pipe 5 away from the corrugated pipe 4. The end of the inclined pipe 18 away from the defoaming branch pipe 5 is inclined downward, and the inclined pipe 18 has a 15° angle with the horizontal plane. The nozzle 6 is fixedly installed at the end of the inclined pipe 18 away from the defoaming branch pipe. Since the radius of the defoaming branch pipe 5 does not coincide with that of the annular main pipe 1, when the defoamer is sprayed into the thickener through the nozzles 6 at the ends of the multiple defoaming branch pipes 5, the defoamer impacts the foam and forms a swirling flow in the thickener, accelerating the aggregation, breakage and dissipation of the foam, thereby improving the defoaming efficiency.

[0030] Nozzle 6 is a fan-shaped nozzle. Specifically, the end of nozzle 6 away from defoaming branch pipe 5 is provided with a flat spray port 19. The spray port 19 sprays a fan-shaped water mist, thereby giving the defoamer a larger spray range and improving defoaming efficiency.

[0031] Example 2:

[0032] like Figure 5 and Figure 6As shown, the difference between this embodiment and Embodiment 1 is that the mounting base 7 is provided with a slide 20 driven by a power device and moving radially along the annular main pipe 1, and the motor 13 is mounted on the slide 20 by bolts. The outer mounting plate 11 is a long strip extending radially along the annular main pipe 1. The outer mounting plate 11 has guide grooves 21 extending along the length direction of the outer mounting plate 11 on both sides along the width direction. The slide 20 has downwardly extending guide portions 22 integrally formed on both sides along the width direction of the outer mounting plate 11. The inner side of the guide portion 22 has a guide block 23 that matches the guide groove 21, thereby improving the sliding stability of the slide 20. The outer mounting plate 11 has a vertically through clearance groove in the middle. The power device is a cylinder 24. The cylinder body of the cylinder 24 is fixedly installed on the outer mounting plate 11 away from the lower mounting seat 9 by bolts. The piston rod of the cylinder 24 extends radially along the annular main pipe 1 into the clearance groove and is fixedly installed with a connecting seat 25. The connecting seat 25 is fixedly installed on the bottom of the slide 20 by bolts.

[0033] Specifically, the extension and retraction of the cylinder 24 drives the slide 20 and the motor 13 to move radially along the annular main pipe 1. When the motor 13 moves towards the center of the annular main pipe 1, the motor 13 drives the end of the defoaming branch pipe 5 with the nozzle 6 to shift towards the center of the annular main pipe 1 via the connecting rod 17. Conversely, when the motor 13 moves away from the center of the annular main pipe 1, the motor 13 drives the end of the defoaming branch pipe 5 with the nozzle 6 to shift away from the center of the annular main pipe 1 via the connecting rod 17. By adjusting the slide 20 and the motor 13 to different positions along the radial direction of the annular main pipe 1, the coverage area of ​​the defoamer sprayed by the nozzle 6 is adjusted.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
