Description

Technical Field

[0001] This utility model relates to the field of defoaming device technology, and in particular to a defoaming device for stirring an air-entraining agent. Background Technology

[0002] Air-entraining agents are admixtures that introduce a large number of uniformly distributed, stable, and closed micro-bubbles into concrete during the mixing process. These micro-bubbles act like ball bearings, reducing friction between particles and increasing the fluidity of the concrete mixture, facilitating construction, especially in pumped concrete where they effectively reduce pumping pressure and improve construction efficiency. These micro-bubbles also cut off capillary channels in the concrete, preventing water penetration and thus improving the concrete's impermeability and frost resistance. Simultaneously, the bubbles alleviate stress caused by the expansion of frozen water, reducing internal damage to the concrete and extending the service life of the concrete structure.

[0003] In existing technologies, the production of air-entraining agents typically requires mixing raw materials with other additives. This mixing process can generate significant amounts of foam, and excessive foam can reduce the stability of the air-entraining agent. Furthermore, the air within the foam may gradually escape during storage or transportation, causing changes in the performance of the air-entraining agent. Additionally, if foam overflows from the equipment during the production process, it can pollute the production environment, causing harm to surrounding soil and water sources. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that a lot of foam may be generated during stirring, and excessive foam may reduce the stability of the air-entraining agent. Therefore, an air-entraining agent stirring and defoaming device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas-entraining agent stirring and defoaming device, comprising a first box, a second box fixedly installed on the bottom surface of the first box, a storage groove opened on the top of the second box, an extension ring slidably installed inside the storage groove, a lifting plate fixedly installed on the outer wall of the extension ring, a rack fixedly installed at the bottom of the lifting plate, a fixed seat fixedly installed on the outer wall of the second box, a second motor fixedly installed on the outer wall of the fixed seat, the output end of the second motor entering the fixed seat and fixedly installed with a gear, the gear meshing with the rack, a box cover provided on the top of the first box, a first motor fixedly installed on the top of the box cover, the output end of the first motor penetrating the box cover and fixedly installed with a rotating shaft, a fixed plate fixedly installed on the outer wall of the rotating shaft, an electric telescopic rod fixedly installed on the top of the fixed plate, and a scraper fixedly installed at the telescopic end of the electric telescopic rod penetrating the fixed plate.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, as Figures 1-5As shown, this utility model provides a gas-entraining agent stirring and defoaming device, including a first box 1, a second box 8 fixedly installed on the bottom surface inside the first box 1, a storage groove 13 opened on the top of the second box 8, an extension ring 14 slidably installed inside the storage groove 13, a lifting plate 15 fixedly installed on the outer wall of the extension ring 14, a rack 25 fixedly installed at the bottom of the lifting plate 15, a fixed seat 22 fixedly installed on the outer wall of the second box 8, a second motor 23 fixedly installed on the outer wall of the fixed seat 22, the output end of the second motor 23 enters the fixed seat 22 and a gear 24 is fixedly installed thereon, the gear 24 meshes with the rack 25, a box cover 3 is provided on the top of the first box 1, a first motor 5 is fixedly installed on the top of the box cover 3, the output end of the first motor 5 passes through the box cover 3 and a rotating shaft 11 is fixedly installed thereon, a fixed plate 19 is fixedly installed on the outer wall of the rotating shaft 11, an electric telescopic rod 20 is fixedly installed on the top of the fixed plate 19, and a scraper 21 is fixedly installed at the telescopic end of the electric telescopic rod 20 passes through the fixed plate 19.

[0027] The effect achieved by the entire embodiment 1 is as follows: when foam is generated, the staff starts the second motor 23 according to the liquid level position. The output end of the second motor 23 drives the gear 24 to rotate, which in turn drives the rack 25 to move. This causes the rack 25 to drive the lifting plate 15 to descend, and the extension ring 14 enters the storage tank 13 until the top of the extension ring 14 moves to the side of the liquid level. At the same time, the staff starts the electric telescopic rod 20. The telescopic end of the electric telescopic rod 20 stretches and pushes the scraper 21 to descend until the scraper 21 moves to the side of the foam. At this time, the scraper 21 rotates, and the scraper 21 can push the foam out of the second box 8, thus completing the defoaming.

[0028] Example 2, as Figures 1-5 As shown, a storage seat 16 is fixedly installed on the outer wall of the extension ring 14, a collection box 17 is slidably installed inside the storage seat 16, and a top plate 18 is fixedly installed on the top of the collection box 17.

[0029] Furthermore, an iron ring 30 is fixedly installed at the bottom of the box cover 3, and a connecting ring 4 is fixedly installed on the outer wall of the first box body 1. A limiting groove 28 is opened at the top of the connecting ring 4, and an electromagnet 29 is fixedly installed on the inner wall of the limiting groove 28. When installing the box cover 3, the worker inserts the iron ring 30 into the limiting groove 28, and then the worker activates the electromagnet 29. The electromagnet 29 generates magnetic force, and the iron ring 30 can be attracted to the electromagnet 29. This completes the installation and prevents the box cover 3 from falling off.

[0030] Furthermore, a positioning groove 31 is provided on the top of the connecting ring 4, and a positioning rod 32 is fixedly installed on the bottom of the box cover 3. When placing the box cover 3, the staff inserts the positioning rod 32 into the positioning groove 31, which can prevent the box cover 3 from rotating during use.

[0031] Furthermore, a feed pipe 6 is installed through and fixed to the top of the box cover 3. A pipe cover 7 is installed on the top of the feed pipe 6. When the material is discharged, the staff will install the pipe cover 7 on the top of the feed pipe 6. At this time, the pipe cover 7 can play a protective role and prevent external dust from entering the first box 1 during mixing.

[0032] Furthermore, a discharge pipe 9 is installed through and fixedly mounted on the bottom surface of the second chamber 8. The bottom of the discharge pipe 9 passes through the first chamber 1 and is equipped with a solenoid valve 10. When the stirring ends, the operator starts the solenoid valve 10, and the stirred liquid can then leave from the discharge pipe 9.

[0033] Furthermore, two stirring rods 12 are symmetrically installed on the outer wall of the rotating shaft 11. When the rotating shaft 11 rotates, it drives the stirring rods 12 to rotate, which in turn generates strong shear force and axial flow, so that the air-entraining agent solution is fully mixed and uniform, and also helps the formation and breaking of foam.

[0034] Furthermore, a T-shaped plate 26 is fixedly installed on the outer wall of the rack 25, and a T-shaped groove 27 is opened on the inner wall of the fixing seat 22. The T-shaped plate 26 and the T-shaped groove 27 are slidably connected to prevent the rack 25 from tilting.

[0035] Furthermore, limit blocks 33 are fixedly installed on both sides inside the storage slot 13, and limit rings 34 are fixedly installed at the bottom of the extension ring 14. When the extension ring 14 moves, it drives the limit rings 34 to move. When the extension ring 14 moves to the top, the top of the limit rings 34 contacts the bottom of the limit blocks 33, thus preventing the extension rings 14 from completely leaving the storage slot 13.

[0036] Furthermore, three evenly distributed support frames 2 are fixedly installed at the bottom of the first housing 1 to support the entire device.

[0037] The effect achieved by the entire embodiment 2 is that during defoaming, the foam leaves the second box 8, contacts the top plate 18, is blocked by the top plate 18, and remains in the collection box 17. When it is finished, the staff turns off the electromagnet 29, and then the iron ring 30 can be pulled out. In this way, the box cover 3 can be removed, and the collection box 17 can be taken out to clean or recycle the foam.

[0038] Working Principle: During use, the operator opens the pipe cap 7 and places the raw materials and additives into the second chamber 8 through the feed pipe 6. The operator then starts the first motor 5, whose output drives the rotating shaft 11 to rotate, which in turn drives the stirring rod 12. The stirring rod 12 then stirs the raw materials and additives. The rotation of the rotating shaft 11 generates strong shear force and axial flow, ensuring thorough and uniform mixing of the air-entraining agent solution, and also aiding in foam formation and breakage. When foam is generated, the operator starts the second motor 23 according to the liquid level. The output of the second motor 23 drives the gear 24 to rotate, which in turn moves the rack 25. This causes the rack 25 to lower the lifting plate 15, allowing the extension ring 14 to enter the storage tank 13 until the top of the extension ring 14 reaches the liquid surface. Simultaneously, the operator starts the electric telescopic rod 20, whose telescopic end extends and pushes the scraper 21 downwards until it reaches the foam. At this point, the scraper 21 rotates. Due to its length and tilt angle, the scraper 21 continuously contacts the foam during rotation. The part of scraper 21 that contacts the foam exerts a force on the foam along the surface of scraper 21. This force can be decomposed into a force perpendicular to the surface of scraper 21 and a force along the length of scraper 21. The force perpendicular to the surface of scraper 21 allows scraper 21 to cut into the foam layer, while the force along the length of scraper 21 pushes the foam out of the second chamber 8. Scraper 21 then pushes the foam out of the second chamber 8, thus completing the defoaming process. During defoaming, the foam leaves the second chamber 8, contacts the top plate 18, and is blocked by the top plate 18, remaining in the collection box 17. When the process is complete, the operator turns off the electromagnet 29, and then pulls out the iron ring 30, allowing the box cover 3 to be removed. The collection box 17 can then be taken out for cleaning or recycling of the foam. When the mixing is finished, the operator activates the solenoid valve 10, allowing the mixed liquid to leave from the discharge pipe 9. When installing the cover 3, the worker inserts the iron ring 30 into the limiting groove 28, and then the worker activates the electromagnet 29. The electromagnet 29 generates magnetic force, and the iron ring 30 can be attracted to the electromagnet 29. This completes the installation and prevents the cover 3 from falling off.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
