Description

Technical Field

[0001] The present invention belongs to the technical field of concrete block production, and specifically relates to an environmentally friendly concrete block moisture preservation and curing device. Background Art

[0002] As a commonly used building material in construction projects, the quality and performance of concrete blocks are directly related to the safety and durability of the entire project. Therefore, in the production and construction process of concrete blocks, moisture preservation and curing is a crucial link. Moisture preservation and curing aims to keep the concrete surface moist, prevent premature evaporation of moisture, and ensure that the hydration reaction of the cement paste is fully carried out, so as to achieve the strength and performance required by the design.

[0003] Traditional methods for moisture preservation and curing of concrete blocks mainly include covering with moisture preservation materials (such as plastic films, wet linen, etc.), spraying water for curing, using constant temperature equipment, etc. However, with the continuous development of construction technology and the continuous expansion of project scale, higher requirements have been put forward for the efficiency and effect of moisture preservation and curing of concrete blocks. Therefore, various new types of moisture preservation and curing equipment have emerged, aiming to improve the curing efficiency and ensure the quality of concrete blocks.

[0004] Steam curing is one of the efficient and rapid methods for concrete moisture preservation and curing, and is widely used in the production of concrete precast components. By introducing steam into the curing chamber, the temperature and humidity in the chamber are increased, accelerating the hydration reaction of the concrete and shortening the curing cycle. However, when traditional steam curing equipment introduces steam, it is often difficult to ensure the uniform distribution of steam in the curing space, and there are obvious differences in temperature and humidity between the upper and lower parts of the curing space and inside and outside the concrete blocks, thus affecting the uniform curing of concrete blocks.

[0005] Therefore, there is an urgent need for an environmentally friendly concrete block moisture preservation and curing device that can solve the problem of uneven curing effect during steam curing. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide an environmentally friendly concrete block moisture preservation and curing device that can improve the uniformity of temperature and humidity distribution in the steam curing space, thereby improving the curing effect of concrete blocks.

[0007] In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0008] An environmentally friendly concrete block moisture conservation device, comprising a conservation tank and a steam assembly; a cover body is arranged at one end of the conservation tank; a support assembly for supporting the concrete blocks is arranged at the inner bottom of the conservation tank; a plurality of air outlets are evenly arranged in the side wall of the conservation tank, and each air outlet is respectively communicated with a constant temperature pipe; a plurality of reflux cavities are arranged on one side of the constant temperature pipe, the reflux cavities are laid from top to bottom along the length direction of the constant temperature pipe, and the volume of the reflux cavities gradually decreases from top to bottom; the outlets of the reflux cavities correspond to the air outlets respectively;

[0009] The bottom of the constant temperature pipe is communicated with a plurality of circulation assemblies, and the circulation assemblies are used for extracting the steam at the bottom of the conservation tank;

[0010] The steam assembly is used for conveying steam into all the constant temperature pipes.

[0011] Adopting the above scheme has the following beneficial effects:

[0012] 1. In this scheme, during conservation, the cover body is opened, then the concrete blocks are placed on the support assembly in the conservation tank, and after closing the cover body, steam is generated by the steam assembly and input into the constant temperature pipes. During the conveying process of the steam, energy loss will inevitably occur, resulting in a temperature drop. When the steam migrates along the inside of the constant temperature pipe, from top to bottom, the steam with a higher temperature (initial temperature) escapes from the topmost air outlet. When the steam migrates to the reflux cavity, a part of the steam enters the reflux cavity, and the other part continues to move along the constant temperature pipe. When this part of the steam flowing into the reflux cavity flows out of the reflux cavity, it will impact the steam normally migrating in the constant temperature pipe, thereby delaying the migration speed of the steam and temporarily retaining the steam in the reflux cavity. At this time, as the steam accumulates in the reflux cavity, the temperature of the steam in the reflux cavity will gradually rise until it approaches the initial temperature of the steam, and then it escapes from the air outlet corresponding to the reflux cavity into the conservation tank. As the migration distance of the steam becomes longer, the heat loss of the steam will gradually increase. Since the volume of the reflux cavity increases in a stepped manner, the farther the steam migrates, the larger the volume of the corresponding reflux cavity, and the more steam is temporarily stored in the reflux cavity, so as to avoid the temperature of the steam escaping from the bottommost air outlet being too low. At the same time, as the steam continuously replenishes and accumulates in the reflux cavity, the temperature in the reflux cavity will gradually rise to supplement the heat loss of the steam during the migration process, so as to ensure that the temperature difference of the steam escaping from the air outlets is relatively small, thereby improving the uniformity of the steam distribution in the conservation tank.

[0013] Compared with the prior art, there is often a temperature gradient in the steam distribution in the conservation tank, resulting in inconsistent conservation effects on different parts of the concrete blocks. However, through the design of the reflux cavity in this scheme, the steam can be effectively supplemented with heat and the distribution can be adjusted during the migration process, so as to ensure that the temperatures of the steam escaping from each air outlet in the conservation tank tend to be the same, improve the uniformity of the steam distribution, and enable the concrete blocks to be more evenly conserved.

[0014] 2. In this solution, due to the improved uniformity of steam distribution and energy utilization efficiency, the concrete blocks can receive more stable and sufficient heat during the curing process, thereby improving the curing effect and quality. This helps to reduce the performance differences and defects of concrete blocks caused by improper curing and improves the overall quality of concrete block products.

[0015] Furthermore, the circulation component includes a collection part; the cross-section of the collection part is disk-shaped, and several concentric rings are axially arranged on the top of the collection part. The adjacent rings are in sliding fit with each other, and the rings are in sliding fit with the collection part; several air inlets are arranged on each ring; a first air inlet chamber and a second air inlet chamber are arranged in each ring from top to bottom. The first air inlet chamber and the second air inlet chamber are not communicated with each other; annular grooves and several second channels are arranged between adjacent first air inlet chambers and between the first air inlet chamber and the collection part. The second channels are used to connect the annular grooves with the first air inlet chamber, and the second channels near the edge of the collection part are connected with a first exhaust pipe; several circumferentially arranged blades are arranged in each second air inlet chamber; a conduit component is connected to the bottom of each second air inlet chamber; a second connecting pipe is arranged between adjacent collection parts, and both ends of the second connecting pipe are respectively connected with the conduit component; the conduit component near the cover body is connected with a second exhaust pipe, and the conduit component far from the cover body is connected with a constant temperature pipe.

[0016] Beneficial effects: When the circulation component is operating, the steam enters the conduit component from the constant temperature pipe and is evenly distributed into the second air inlet chambers in each ring, pushing the blades to rotate and driving the rings to rotate, thereby changing the position of the air inlets, so that the steam can more comprehensively contact and collect the low-temperature steam at the bottom of the curing tank. This active circulation mechanism greatly improves the steam circulation efficiency and ensures the uniform distribution of steam and greenhouse balance in the curing tank. At the same time, since the circulation component can continuously re-introduce and heat the low-temperature steam at the bottom of the curing tank, the temperature stratification phenomenon caused by natural convection or heat conduction of steam in the curing tank is avoided. This helps to maintain the temperature stability in the curing tank, enables the concrete blocks to be cured in a more uniform temperature environment, and improves the uniformity and reliability of the curing effect.

[0017] Furthermore, the steam component includes a steam generator and a first connecting pipe; the output end of the steam generator is connected to the first connecting pipe, and the other end of the first connecting pipe is connected to all the constant temperature pipes.

[0018] Beneficial effects: As the source of steam, the steam generator concentrates and efficiently distributes the steam to each constant temperature pipe through the first connecting pipe. This design ensures the stability and continuity of steam supply and avoids curing interruption caused by the failure of a single steam source. At the same time, as the bridge connecting the steam generator and the constant temperature pipes, the first connecting pipe enables the steam to be quickly and evenly transmitted to each area.

[0019] Further, the support assembly includes a slide rail.

[0020] Beneficial effects: The design of the slide rail makes it more convenient and efficient to pick up and place concrete blocks. The operator only needs to slide the concrete blocks along the slide rail to easily complete the picking and placing actions, greatly saving time and labor costs.

[0021] The slide rail not only supports the concrete blocks but also separates them from the bottom of the curing tank, forming a certain gap. This gap provides a second channel for the steam to circulate at the bottom of the concrete blocks, enabling the steam to penetrate more fully into all corners of the concrete blocks, improving the uniformity and effectiveness of curing. At the same time, it avoids the problems of heat accumulation and uneven temperature caused by the direct contact of the concrete blocks with the bottom of the curing tank.

[0022] Further, the conduit assembly includes several pairs of conduits, and the number of pairs of conduits corresponds to the second air inlet chamber; the conduits are symmetrically arranged in the collection part respectively; the conduits do not affect each other.

[0023] Beneficial effects: By connecting the conduits to the respective second air inlet chambers, steam can enter each second air inlet chamber to drive each ring to rotate independently. Since each pair of conduits independently supplies steam to its corresponding second air inlet chamber, the rotation of each ring does not interfere with each other. This independence allows each ring to rotate independently according to its own force condition and steam pressure. Compared with the synchronous rotation of all rings, this solution can provide more combinations for the distribution positions of the air outlet, thus promoting the uniform circulation of steam in the curing tank.

[0024] Further, check valves are provided between adjacent return chambers in the constant temperature pipe.

[0025] Beneficial effects: By setting the check valves, it can prevent the steam from flowing back when moving in the constant temperature pipe, ensuring that the steam always flows in the predetermined direction, thus maintaining the normal curing environment in the curing tank.

[0026] Further, a first pressure relief valve is provided at the top of the curing tank.

[0027] Beneficial effects: During the curing process, as the steam is continuously injected and the temperature rises, the pressure in the curing tank will gradually increase. By setting a first pressure relief valve at the top of the curing tank, if the pressure exceeds the set safety value, the first pressure relief valve will automatically open to release some steam, thereby reducing the pressure in the tank and preventing safety accidents such as the rupture and explosion of the curing tank caused by excessive pressure.

[0028] Further, a second pressure relief valve is provided at the bottom of the constant temperature pipe.

[0029] Beneficial effects: By providing a second pressure relief valve at the bottom of the constant temperature pipe, it is possible to prevent steam from directly flowing into the collection part through the constant temperature pipe and then discharging through the second exhaust pipe, which may cause the steam to fail to escape normally from the air outlet or the amount of steam escaping from the air outlet to be small, thus affecting the curing effect in the curing tank.

[0030] Further, a first channel is respectively provided between the constant temperature pipe and the air outlet; an adjustment component is provided in each first channel; the adjustment component includes a sliding groove; the sliding groove vertically penetrates the first channel; a first fitting block and a second fitting block are sequentially arranged in the sliding groove from top to bottom, both the first fitting block and the second fitting block are slidably matched with the sliding groove, the bottom of the first fitting block is slidably matched with the top of the second fitting block, and when the second fitting block moves horizontally, the first fitting block moves vertically; a through groove is provided in the second fitting block for communicating the first channel; a spring for pushing the second fitting block to move horizontally is further provided on the side of the sliding groove away from the constant temperature pipe; a transmission rod is provided on the side of the second fitting block close to the constant temperature pipe, the transmission rod is horizontally embedded in the side wall of the sliding groove, and the transmission rod is slidably matched with the side wall of the sliding groove; a bimetallic strip is provided at one end of the transmission rod away from the second fitting block, and when the bimetallic strip deforms, it pushes the transmission rod to move horizontally; the first fitting blocks are integrally provided.

[0031] Beneficial effects: The bimetallic strips in each adjustment component can sense the temperature of the steam in each first channel. When the steam temperature reaches the preset temperature, the bimetallic strip deforms, pushing the transmission rod to move horizontally. The transmission rod pushes the second fitting block to move horizontally in the sliding groove and compress the spring. After the first fitting block loses the support of the second fitting block, it moves downward along the side wall of the sliding groove until the through groove coincides with the first channel, so that the first channel is connected; since all the first fitting blocks are integrally provided, when all the bimetallic strips deform, the first fitting blocks will move downward synchronously, so that the through grooves in each first fitting block are respectively connected to the first channel, thereby realizing that the temperatures of the steam escaping from the first channels are consistent.

[0032] By using the bimetallic strip to sense and respond to the change of steam temperature, the on-off state of each first channel is automatically adjusted to ensure that all channels reach the preset temperature and open at the same time, so that the steam can be evenly distributed to every corner in the curing tank. This synchronous control mechanism effectively avoids local overheating or overcooling phenomena and improves the overall curing uniformity of concrete blocks.

[0033] Further, the constant temperature pipe is made of different heat insulation materials, and the heat insulation performance of the constant temperature pipe gradually increases from top to bottom.

[0034] Beneficial effects: Considering that steam will gradually cool down during the flow process due to heat exchange, this design ensures that the heat conduction in the upper part of the constant temperature pipe is relatively fast, while the lower part can more effectively maintain the steam temperature. In this way, the temperature of the steam escaping from either the upper or lower part of the constant temperature pipe can tend to be consistent, greatly improving the uniformity of the steam temperature in the curing tank.

[0050] Specifically, the circulation component includes a collection part 4; as shown in the appendix Figure 3 As shown, in this embodiment, the collection part 4 is located at the bottom of the curing tank 1. The cross-section of the collection part 4 is disk-shaped. There are 3 collection parts 4 in total (set according to the actual situation).

In this embodiment, there are two second channels 404 on both sides of each annular groove 403. The second channels 404 in the adjacent rings 402 are used to connect the annular groove 403 with the first air inlet chamber 406, and the second channels 404 in the outermost ring 402 are used to communicate with the outside.

[0052] The steam assembly is used to deliver steam to all of the constant temperature tubes 5.

[0053] Specifically, the steam assembly includes a steam generator 2 and a first connecting pipe 3; the output end of the steam generator 2 is in communication with the first connecting pipe 3, and the other end of the first connecting pipe 3 is in communication with all of the constant temperature tubes 5, that is, the tops of all of the constant temperature tubes 5 converge at the first connecting pipe 3 and are in communication with the first connecting pipe 3.

[0054] A first channel 107 is respectively provided between each of the constant temperature tubes 5 and the air outlet 105; an adjustment assembly is provided within each of the first channels 107; the adjustment assembly includes a sliding groove 1074; as shown in the attached Figure 6 figure, the sliding groove 1074 vertically penetrates the first channel 107; a first mating block 1071 and a second mating block 1073 are sequentially arranged from top to bottom within the sliding groove 1074, both the first mating block 1071 and the second mating block 1073 are slidably engaged with the sliding groove 1074, the bottom of the first mating block 1071 is slidably engaged with the top of the second mating block 1073, when the second mating block 1073 moves horizontally, the first mating block 1071 moves vertically, specifically, in this embodiment, the bottom of the first mating block 1071 is a smooth inclined surface, and the top of the second mating block 1073 is also a smooth inclined surface, and the two are mutually attached; a through groove 1072 is provided within the second mating block 1073, the through groove 1072 is used to communicate with the first channel 107, in this embodiment, the cross-sectional dimension of the through groove 1072 is the same as the cross-sectional dimension of the first channel 107; a spring 1075 for pushing the second mating block 1073 to move horizontally is further provided on the side of the sliding groove 1074 away from the constant temperature tube 5, as shown in the attached Figure 6 figure, the spring 1075 is arranged horizontally, in this embodiment, one end of the spring 1075 is welded and fixed to the second mating block 1073, and the other end of the spring 1075 is embedded within the side wall of the sliding groove 1074; a transmission rod 1077 is welded and fixed to the side of the second mating block 1073 close to the constant temperature tube 5, the transmission rod 1077 is horizontally embedded within the side wall of the sliding groove 1074, and the transmission rod 1077 is slidably engaged with the side wall of the sliding groove 1074; a bimetallic strip 1076 is provided at the end of the transmission rod 1077 away from the second mating block 1073, when the bimetallic strip 1076 deforms, it pushes the transmission rod 1077 to move horizontally, specifically, as shown in the attached Figure 6As shown, in this embodiment, the bottom of the bimetallic strip 1076 is fixed by bolts under the first channel 107, and the top of the bimetallic strip 1076 is in contact with the transmission rod 1077. When the bimetallic strip 1076 bends, the top of the bimetallic strip 1076 pushes the transmission rod 1077 to move into the sliding groove 1074; the first matching blocks 1071 are all integrated. Specifically, in this embodiment, a groove (not shown in the figure) is opened on one side of all the first matching blocks 1071, and a shaft (not shown in the figure) is slidably fitted in the groove. The shaft welds all the first matching blocks 1071 in series, that is, all the first matching blocks 1071 are driven by the shaft to achieve synchronous movement.

[0055] The specific implementation process is as follows:

[0056] When curing the concrete block 8, the cover 101 is rotated upward to open, the concrete block 8 is placed on the slide rail 102 and sent to the inside of the curing tank 1, and then the cover 101 is closed. The steam generator 2 is started, and the steam generated by the steam generator 2 is transported to the constant temperature pipe 5 in the curing tank 1 through the first connecting pipe 3. The steam flows from top to bottom along the constant temperature pipe 5. For example, the temperature discharged by the steam generator 2 is 75°C, and the curing tank 1 requires 65°C steam. When the steam is transferred to the constant temperature pipe 5, it is assumed that due to heat exchange, the steam flows to the first channel 107 (herein referred to as A, as shown in the attached figure) on the top layer. Figure 3 As shown in the figure, the first channel 107 is named A, B, C, D, E from top to bottom, the temperature of the steam is 65°C, and the steam passes through AE in sequence. In the absence of the reflux chamber 501, the temperature will gradually decrease from 65°C to 61°C. The temperature of the steam decreases by 1°C every time the steam passes a certain distance. In this embodiment, as shown in the attached Figure 3 As shown, four reflux chambers 501 are arranged on one side of each thermostatic tube 5. When the steam passes through the first reflux chamber 501 from top to bottom, the steam accumulates in the reflux chamber 501. At this time, the steam temperature in the first reflux chamber 501 drops from 64°C to 65°C. By analogy, as the steam flows downward, the more heat is lost, the larger the volume of the reflux chamber 501 downward is, and the larger the amount of steam that can be temporarily stored is, until the steam temperature in all the reflux chambers 501 rises to 65°C, as shown in the attached figure. Figure 6 As shown, all the bimetallic strips 1076 are deformed, pushing the transmission rod 1077 to move, and the transmission rod 1077 pushes the second matching block 1073 to move to the right. After the first matching block 1071 loses the support of the second matching block 1073, it moves downward, so that the through groove 1072 coincides with the first channel 107, and the 65°C steam passes through the first channel 107 at the same time, and escapes into the curing tank 1 through the air outlet 105, so as to perform steam curing on the concrete blocks 8 in the curing tank 1.

[0057] Since a check valve 502 is provided in the constant temperature pipe 5, the steam can only flow along the established route and will not flow back.

[0058] At the same time, as shown Figure 6 in the figure, a part of the steam in the constant temperature pipe 5 enters the curing tank 1, and the other part continues to flow along the constant temperature pipe 5 and enters the first conduit 408, the second conduit 409, and the third conduit 410 ( Figure 5 on the left side in the figure), respectively increasing the air pressure in the second intake chamber 407, thereby pushing the blade 405 to rotate, and then entering the second exhaust pipe 7 from the symmetrically arranged ( Figure 5 on the right side in the figure) first conduit 408, second conduit 409, and third conduit 410, and being discharged from the curing tank 1 through the second exhaust pipe 7.

[0059] When the blade 405 rotates, it will drive the ring 402 to rotate. The rotation of the ring 402 causes the intake ports 401 on the ring 402 to continuously change positions, thereby promoting the steam circulation in the curing tank 1. As the steam in the curing tank 1 increases, the steam at the bottom of the curing tank 1 will enter the first intake chamber 406 through the intake port 401, and sequentially pass through the second channel 404, the annular groove 403, the second channel 404, and the first exhaust pipe 6, and be discharged from the curing tank 1 through the first exhaust pipe 6.

[0060] During the whole process, since a second pressure relief valve 104 is provided at the bottom of the constant temperature pipe 5, the second pressure relief valve 104 will only open when the pressure in the constant temperature pipe 5 reaches the preset pressure, allowing the steam to pass through. In this way, the steam can preferentially enter the curing tank 1 through the first channel 107, avoiding the steam directly flowing into the first conduit 408, the second conduit 409, and the third conduit 410 from the bottom of the constant temperature pipe 5 and then being discharged through the second exhaust pipe 7.

[0061] At the same time, if the pressure in the curing tank 1 exceeds the set safety value, the first pressure relief valve 103 will automatically open to release some steam, thereby reducing the pressure in the tank and preventing safety accidents such as the rupture and explosion of the curing tank 1 caused by excessive pressure.

[0062] The above are only the embodiments of the present invention, and the specific structures and / or common knowledge such as characteristics well known in the art are not described in detail here.
