Description

Technical Field

[0001] The utility model relates to the technical field of cooling ready-mixed concrete, in particular to a ready-mixed concrete cooling device. Background Art

[0002] During the construction process, there is a large demand for concrete. In many cases, it is put into use directly after mixing. At this time, the temperature of the concrete is high, and the collapse speed is lost quickly after pouring, which will have a negative impact on the construction quality and speed. Therefore, the concrete needs to be cooled. The existing solutions mainly include using admixtures, increasing water consumption and cooling with cold water. The amount of admixtures and water added is difficult to determine, and it is easy to cause quality problems such as concrete segregation, delayed final setting time and reduced strength due to over-addition.

[0003] Chinese patent publication number CN218365633U discloses a ready-mixed concrete cooling device comprising a cylindrical barrel with four support legs at its bottom, an inner layer disposed on its inner side, a cooling chamber disposed between the cylindrical barrel and the inner layer, a feeding port at its top, a discharge port connecting the cylindrical barrel and the inner layer to the bottom, and four rotating tubes mounted vertically on the cylindrical barrel. This device has a simple structure and can cool concrete while it is being mixed. Rather than relying solely on cooling water added to the concrete, it can also cool the entire device, improving the cooling effect on the concrete.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing ready-mixed concrete cooling device cannot quickly and evenly stir the concrete inside, resulting in poor concrete mixing effect, and cannot quickly and effectively absorb heat and cool down during mixing.

Push rod 1 502 is located at the output end of cylinder 501. Connecting plate 503 is located on top of push rod 1 502. Push rod 2 504 is located on top of connecting plate 503. There are four push rods 2 504. Starting cylinder 501 drives push rod 1 502 to move up and down. Push rod 1 502, through connecting plate 503, drives push rod 2 504 to move up and down. The cooling assembly includes a heat sink 505, a heat dissipation port 506, a heat insulating ring 507, a slide 508 and a push ring 509; the push ring 509 is arranged at the top of the push ring 509, the heat sink 505 is arranged at the top of the support column 2, the heat dissipation port 506 is arranged at the top of the heat sink 505, and the shape of the heat dissipation port 506 is upwardly diffused to facilitate heat dissipation of the cooling water in the heat sink 505. A heat exchange plate 515 is arranged on the side of the heat exchange plate 515, and a connecting block 2 514 is arranged on the inner side of the heat exchange plate 515.

[0036] Example 2

[0037] like Figure 6-Figure 7 As shown, the present invention proposes a ready-mixed concrete cooling device. Compared with the first embodiment, this embodiment introduces the structure of the mixing mechanism in detail:

[0038] The stirring mechanism includes a motor 601, a rotating shaft 602, a connecting frame 607, a circular gear 608, a connecting shaft 609 and a conveying assembly; the stirring box 612 is arranged on the inner side of the heat exchange plate 515, the motor 601 is arranged on the top of the stirring box 612, the rotating shaft 602 is arranged at the output end of the motor 601, the connecting frame 607 is arranged on the outer side of the rotating shaft 602, the connecting shaft 609 is arranged at one end of the connecting frame 607 away from the rotating shaft 602, the circular gear 608 is arranged on the top of the connecting shaft 609, and the outer side of the connecting shaft 609 is arranged There is a stirring blade 610, and a gear ring 611 is provided on the inner side of the stirring box 612. The inner side of the gear ring 611 is meshed with the outer side of the circular gear 608. The starting motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the circular gear 608 to rotate around the rotating shaft 602 through the connecting frame 607. Since the circular gear 608 and the gear ring 611 are meshed, the circular gear 608 can rotate on its own. The circular gear 608 drives the stirring blade 610 to rotate through the connecting shaft 609, so that the stirring blade 610 rotates and revolves at the same time. The conveying assembly includes a spiral blade 603, a guide plate 604, a transmission pipe 605 and a fixed platform 606; the spiral blade 603 is arranged on the outside of the rotating shaft 602, the transmission pipe 605 is rotatably arranged on the outside of the spiral blade 603, and the fixed platform 606 is arranged on the outside of the transmission pipe 605. An inclined surface is provided on the fixed platform 606 to facilitate the flow of concrete into the transmission pipe 605. The guide plate 604 is provided at the top of the transmission pipe 605, and the bottom of the guide plate 604 and the top of the spiral blade 603 are in the same plane. When the concrete is transported to the top through the transmission pipe 605, the guide plate 604 will divert the concrete outward, thereby continuously transporting the concrete at the bottom to the top for re-mixing.

[0039] In summary, when the present invention is used, concrete is poured into the mixing box 612, and then the motor 601 and the cylinder 501 are started at the same time. The motor 601 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the circular gear 608 to rotate around the rotating shaft 602 through the connecting frame 607. Since the circular gear 608 and the gear ring 611 are meshed, the circular gear 608 can rotate on its own. The circular gear 608 drives the stirring blade 610 to rotate through the connecting shaft 609, so that the stirring blade 610 rotates and revolves at the same time, thereby fully mixing the concrete. At the same time, the concrete at the bottom of the mixing box 612 is transported into the transmission pipe 605 through the inclined surface of the fixed platform 606, and the rotating shaft 602 drives the spiral blade 603 to rotate. When the spiral blade 603 rotates, the concrete is continuously transported upward. When it is transported to the top of the concrete, the guide plate 604 diverts the concrete outward, thereby continuously transporting the concrete at the bottom to the top for re-mixing, and during the mixing process During the process, the cylinder 501 drives the push rod 1 502 to move up and down, and the push rod 1 502 drives the push rod 2 504 to move up and down through the connecting plate 503, and the push rod 2 504 drives the push ring 509 to move. When the push ring 509 moves upward, it can drive the blocking ring to move in the slide groove 508 through the connecting block 1 510, thereby connecting the two compartments, so that the cooling water between the heat insulation ring 507 and the heat exchange plate 515 flows into the other compartment, and the push ring 509 flows the cooling water between the heat dissipation box 505 and the heat insulation ring 507 through the connecting port at the top of the heat insulation ring 507 to the compartment of the heat exchange plate 515, so as to absorb heat and cool the concrete. When the push rod 2 504 descends, it drives the push ring 509 to descend. At this time, the rotating door is opened under the upward impact of the water, and the cooling water at the bottom flows to the top of the push ring 509, thereby completing the replacement of the cooling water in the two compartments, and the used cooling water is quickly dissipated through the heat dissipation port 506.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
