Description

Technical Field

[0001] This invention relates to the field of concrete curing equipment technology, and specifically to a cooling water circulation device for lining concrete curing. Background Technology

[0002] In the construction of large-volume lining concrete for tunnels, water conservancy tunnels and other projects, temperature cracks caused by the accumulation of hydration heat are the core quality hazards. After such concrete is poured, the hydration reaction will continuously release a large amount of heat. Due to its large volume and low thermal conductivity, the internal heat is difficult to dissipate quickly, which can easily form a temperature gradient of "high inside and low outside" and cause penetrating cracks. Therefore, most of them achieve internal temperature control by introducing cooling water through pre-set cooling channels.

[0003] While current technology can remove internal heat from concrete using cooling water, significant shortcomings exist in the treatment and recycling of the discharged cooling water, leading to unstable continuous temperature control. Currently, there are two main methods for treating the hot water discharged from the cooling channels: one is direct discharge, which, while simple, consumes a large amount of cooling water for the lining concrete, with large-scale projects requiring thousands of cubic meters of cooling water per pour, resulting in severe water waste; the other is simple recirculation, where the discharged hot water is simply piped back to the inlet and reintroduced into the channels without effective cooling. Because the discharged water temperature has increased, the temperature gradient between the recirculated water and the concrete interior narrows, causing a sharp drop in heat exchange efficiency, failing to meet subsequent temperature control requirements. Furthermore, insufficient local heat exchange may lead to temperature peaks within the concrete, still increasing the risk of cracking. Some improved solutions attempt to add cooling water tanks to cool the discharged water, but these mostly rely on natural heat dissipation, resulting in low cooling efficiency (only 0.5-1℃ / h), which is insufficient to meet the cooling water circulation requirements.

[0004] In summary, achieving efficient cooling of circulating water is of great significance for the curing of concrete components, in order to realize the curing function of stable reflux circulation; in view of this, we propose a cooling water circulation device for the curing of lining concrete. Summary of the Invention

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 The present invention will describe the above technical solution in detail through the following embodiments: The cooling water circulation device for lining concrete curing in this embodiment includes a water storage tank 4 for storing cooling water for curing. A base plate 1 is installed at the bottom. The water storage tank 4 is equipped with a water inlet and a water outlet. It belongs to the existing tank structure and serves to store the circulating cooling water to provide cooling water for subsequent large-volume lining concrete curing.

[0021] Specifically, the cooling water entering the large-volume concrete lining for cooling will absorb heat and rise in temperature before being discharged due to heat conduction. Considering that the heated cooling water cannot be directly recirculated to cool the large-volume concrete lining, good heat exchange efficiency needs to be maintained; therefore, this embodiment, for example... Figures 3-6 The structure shown includes a cooling treatment section 6, through which heated circulating water is guided into the vertical liquid chamber 61 via an external drainage pipe 7 connected to the injection port 611; a water wheel 62 is rotatably installed inside the vertical liquid chamber 61, and the high-temperature circulating water introduced through the drainage pipe 7 drives the water wheel 62 to rotate by flushing from top to bottom.

[0022] This embodiment considers the need for effective heat exchange to cool the heated water. A reciprocating moving assembly 63, coaxially connected to the water turbine 62, is symmetrically installed outside the vertical liquid tank 61. Figures 3-7The structure shown includes a stop block 65 installed between two reciprocating moving components 63 within the vertical liquid tank 61. The stop block 65 is positioned below the water wheel 62 and is used to reciprocate horizontally, thereby reciprocating to abut against the rocker unit 64 mounted on both sides. This causes one side of the rocker unit 64 to be lowered while the other side is raised. The rocker unit 64 includes a perforated cover plate 641 filled with heat-exchange copper particles. As the rocker unit 64 rotates, the copper particles roll within the perforated cover plate 641, allowing them to alternately slide out and be exposed to the outside air for heat dissipation. This achieves reciprocating and alternating heat exchange, ensuring the cooling of the heated water. The copper particles have a good thermal conductivity and excellent heat conduction and dissipation performance, significantly improving efficiency compared to water-based heat dissipation.

[0023] Specifically, the vertical liquid tank 61 is externally fixed with a mounting plate base 66, such as... Figure 7 As shown in the embodiment, the reciprocating moving component 63 includes a disc 631 coaxially fixedly connected to the shafts at both ends of the waterwheel 62. An eccentrically positioned protruding rod 632 is provided on the disc 631. The protruding rod 632 is slidably mounted on the transmission sleeve plate 633 via a sliding groove 6331. A sector plate 634 is fixedly connected to the transmission sleeve plate 633, and a shaft hole 6301 for rotatably mounting on the mounting plate base 66 is provided at the connection point. To achieve horizontal reciprocating movement, a first protruding tooth 6341 is provided on the outer edge of the sector plate 634. Simultaneously, a sliding rod 635 is horizontally slidably mounted on the mounting plate base 66. The sliding rod 635 is driven by a second protruding tooth 6351 meshing with the first protruding tooth 6341. The rotation of the waterwheel 62 drives the disc 631 to rotate, thereby achieving the reciprocating movement of the sliding rod 635 in the horizontal direction.

[0024] In order to resist the alternating downward pressure of the rocker units 64 on both sides for heat exchange, such as Figure 4 and Figure 6 In the structure shown, the inner sides of the two sliding rods 635 are fixedly connected to the abutment 65 via a connecting plate 636. Simultaneously, the vertical liquid tank 61 is provided with a movable groove 601 for horizontally sliding the connecting plate 636. To prevent the abutment 65 from affecting the direction of water descent, in this embodiment, the abutment 65 is as follows... Figure 6 As shown, the funnel-shaped structure has a gradually decreasing diameter from top to bottom and a smooth, continuous surface. The abutment block 65 has a guide cavity 651 with an upper opening, and the cavity wall of the guide cavity 651 has a drain hole. Water can flow into the guide cavity 651 and then be discharged from the drain hole, which will guide the water to contact the copper particles filled in, thereby achieving heat exchange.

[0025] Specifically, such as Figure 6 and Figure 8In the structure shown, two sets of protrusions 67 are fixedly installed on the vertical liquid tank 61. The perforated cover plate 641 is rotatably installed on each set of protrusions 67 through the lugs 642 fixedly connected in the middle of the outer wall. A torsion spring 643 is installed between the perforated cover plate 641 and the tank wall of the vertical liquid tank 61. The torsion spring 643 maintains the tendency of the externally pressing down on the perforated cover plate 641. A rotating groove 602 is provided on the vertical liquid tank 61 for inserting and rotating the perforated cover plate 641. After heat exchange, the copper particles on one side are heated and the block 65 separates after circulation. The perforated cover plate 641 of the heated copper particles rotates under the action of the torsion spring 643, so that the copper particles roll to the outer end of the perforated cover plate 641 and are exposed to the air for heat dissipation. At this time, the perforated cover plate 641 on the other side is pressed down and the copper particles roll in to continue heat exchange. In other embodiments, in order to improve the heat dissipation efficiency of the copper particles, a cooling fan can be installed outside the vertical liquid tank 61 to blow air.

[0026] To prevent overflow due to excessive liquid, an overflow port 612 is provided on the vertical liquid tank 61 and below the rotating groove 602, and a drain port 613 is provided at the bottom of the vertical liquid tank 61. The drain port 613 is connected to the coil heat dissipation fins 2 through the guide pipe 5. A cooling fan 3 is installed on the coil heat dissipation fins 2 for heat dissipation. The drain port of the coil heat dissipation fins 2 is connected to the water storage tank 4. In other embodiments, multiple cold treatment units 6 can be connected in series according to the concrete specifications to deal with the situation of excessively high temperature.

[0027] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
