Description

Technical Field

[0001] This utility model relates to the field of low-carbon concrete pipe pile technology, specifically a waste heat recovery and utilization device for low-carbon concrete pipe piles. Background Technology

[0002] Low-carbon concrete pipe piles refer to green building materials whose carbon emissions are significantly lower than those of traditional concrete pipe piles throughout their entire life cycle, from raw material production, product manufacturing, transportation, construction, and even final disposal. It is not merely a label for the final product, but rather a "low-carbon" production philosophy and technological system that permeates the entire industrial chain. Its core objective is to minimize the "carbon footprint" through a series of technological innovations, serving the national "dual-carbon" strategy.

[0003] In the production process of low-carbon concrete pipe piles, a waste heat recovery device is required. Chinese utility model patent CN212576426U discloses a waste heat recovery device for the concrete pipe pile production process, including a grinding cylinder, a mounting frame, and a base. The grinding cylinder is rotatably connected within the mounting frame, which is welded and fixed to the base. A positioning plate is welded and fixed to the upper middle part of the mounting frame, and a water-absorbing sponge is placed inside the positioning plate. Guide tubes are fixed to the upper ends of the mounting frame on the front and rear sides of the water-absorbing sponge, and nozzles are fixed to the guide tubes. This utility model dissipates heat from the grinding cylinder through the nozzles, improving the equipment's service life. Hot water is collected through a collection box, and heat loss is slowed down through the combination of insulation boards, insulation boxes, and partitions, achieving heat recovery. The water-absorbing sponge facilitates the collection of water vapor, reducing water waste. Transparent baffles and an electric telescopic rod prevent water splashing, avoiding waste and pollution. This device achieves heat dissipation from the grinding cylinder while simultaneously recovering and utilizing the heat.

[0004] However, in the process of using this utility model, existing devices mostly adopt direct spray cooling, which can reduce the equipment temperature to a certain extent, but the heat recovery is insufficient, and the high-temperature waste gas is not effectively treated and utilized, thus failing to achieve the dual goals of energy recycling and environmentally friendly production, and cannot meet production needs. Therefore, a low-carbon concrete pipe pile waste heat recovery and utilization device is proposed to solve the problems mentioned above. Utility Model Content

It solves the problem that existing devices mostly adopt direct spray cooling, which can reduce the equipment temperature to a certain extent, but the heat recovery is insufficient and the high-temperature waste gas is not effectively treated and utilized, thus failing to achieve the dual goals of energy recycling and environmentally friendly production, and failing to meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery and utilization device for low-carbon concrete pipe piles, including a base and a production equipment fixedly connected to the top of the base. A fixed box is fixedly connected to the side of the top of the base away from the production equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1 to 3This embodiment of a low-carbon concrete pipe pile waste heat recovery and utilization device includes a base 1 and a production equipment 2 fixedly connected to the top of the base 1. A fixed box 3 is fixedly connected to the top of the base 1 away from the production equipment 2. The fixed box 3 is equipped with a waste heat recovery mechanism that can recover waste heat. The waste heat recovery mechanism includes a heat exchange tank 4 fixedly connected to the inside of the fixed box 3. An annular heat exchange pipe 5 is fixedly connected to the outer peripheral wall of the heat exchange tank 4. An insulation box 6 is provided on the back of the fixed box 3. Two storage tanks 7 extending to the top of the insulation box 6 are fixedly connected inside the insulation box 6. A connecting pipe 8 is fixedly connected between the front storage tank 7 and the heat exchange tank 4.

[0024] Specifically, the insulated box 6 is fixedly connected to the top of the base 1, the top of the base 1 is fixedly connected to a booster pump that can be connected to the connecting pipe 8, the top of the insulated box 6 is fixedly connected to a cover plate 10, and the inside of the insulated box 6 is fixedly connected to an insulation filling plate 11 that can simultaneously insulate two storage tanks 7, while the two storage tanks 7 are connected in series through a pipe.

[0025] It should be noted that the core of this waste heat recovery mechanism lies in using the high-temperature exhaust gas emitted from production equipment 2 to heat the working fluid. The high-temperature exhaust gas is guided through a pipeline to the annular heat exchange pipe 5, where its heat is transferred through the pipe wall to the working fluid in the heat exchange tank 4, raising its temperature. The heated working fluid is then transported through a connecting pipe 8 to a storage tank 7 for later use. It can be used for preheating, heating, or providing domestic hot water in other parts of the production line, thereby achieving efficient recovery and utilization of waste heat.

[0026] Please see Figure 1 and Figure 4 In this embodiment, a purification chamber 12 is fixedly connected to the upper surface of the production equipment 2, a connecting pipe 13 is fixedly connected between the purification chamber 12 and the production equipment 2, an air supply pipe 9 is fixedly connected between the purification chamber 12 and the annular heat exchange pipe 5, an installation frame 14 is slidably connected inside the purification chamber 12, a sealing installation plate 15 extending to the outside of the purification chamber 12 is fixedly connected to one side of the installation frame 14, and a purification filter element 16 is fixedly connected inside the installation frame 14.

[0027] Specifically, there are three mounting frames 14 and three sealing mounting plates 15, and the types of purification filter elements 16 in the three mounting frames 14 are all different.

[0028] It should be noted that the sealing mounting plate 15 is tightly fitted to the purification chamber 12 through the sealing ring to ensure that the exhaust gas will not leak. The first-stage purification filter element 16 can use a metal filter screen to intercept larger particles, the second-stage purification filter element 16 can use a high-efficiency bag filter element to capture fine dust, and the third-stage purification filter element 16 can be equipped with an activated carbon filter element to adsorb harmful gases, thereby achieving deep purification of the exhaust gas.

[0029] Please see Figure 1 In this embodiment, the top of the production equipment 2 is fixedly connected to a feed hopper 17 extending into it, and the bottom of the base 1 is fixedly connected to four support pads. The bottom of the support pads may be provided with an anti-slip rubber layer to increase friction and prevent the equipment from shifting during operation.

[0030] The working principle of the above embodiments is as follows:

[0031] When concrete pipe piles are cured or processed at high temperatures in production equipment 2, a large amount of high-temperature exhaust gas is generated. This exhaust gas is first introduced into the purification chamber 12 through the connecting pipe 13. In the purification chamber 12, the exhaust gas passes through three different types of purification filter elements 16 in sequence. Dust and other impurities are filtered out step by step to obtain clean hot air. The clean hot air then enters the annular heat exchange pipe 5 in the fixed box 3 through the air supply pipe 9. The hot air in the annular heat exchange pipe 5 exchanges heat fully with the medium in the heat exchange tank 4, transferring its own heat to the working fluid. The cooled exhaust gas can finally be discharged from the end of the annular heat exchange pipe 5 or further treated. At the same time, the working fluid in the heat exchange tank 4 is heated and can be pumped into the storage tank 7 on the front of the insulation box 6 through the connecting pipe 8 under the drive of the booster pump.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
