Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of autoclave curing, in particular to a concrete block autoclave curing waste heat recovery and utilization device. Background Art
[0002] Autoclaved aerated concrete blocks are a kind of porous concrete products made of fly ash, lime, cement, gypsum, slag and other main raw materials, with appropriate amount of gas generating agent, regulator, bubble stabilizer, and through processes such as batching, mixing, pouring, static stopping, cutting and high-pressure steaming. Autoclaved aerated concrete blocks are an excellent new type of building material with advantages such as environmental protection. Prefabricated autoclaved aerated concrete block assembly slabs have the advantages of saving finished product stacking space, saving masonry labor, reducing construction operations, speeding up on-site construction progress, and improving construction efficiency.
[0003] However, the existing steam pressurization device does not have a corresponding waste heat recycling component, and the waste heat is directly dissipated to the outside, causing a certain amount of resource waste. Therefore, a concrete block autoclave curing waste heat recovery and utilization equipment is needed to solve the above technical problems. Utility Model Content
[0004] The main purpose of the utility model is to provide a concrete block autoclave curing waste heat recovery and utilization device, which can effectively solve the technical problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A concrete block autoclave curing waste heat recovery device comprises a base, a curing box is fixed on the top surface of the base, the curing box is divided into a cavity and a curing chamber by a partition, a spiral tube is fixed in the cavity, a spiral ramp is fixed at the bottom end of the cavity, and a liquid outlet trough connected to the cavity is provided at the bottom end of the curing chamber.
[0007] As a further solution of the utility model, the bottom wall of the curing cavity is arc-shaped and guides into the cavity.
[0008] As a further solution of the utility model, the height of the liquid outlet trough is higher than the highest point of the spiral ramp.
[0009] As a further solution of the utility model, a liquid inlet pipe and a liquid outlet pipe are fixedly connected to the liquid inlet end and the liquid outlet end of the spiral tube respectively.
[0010] As a further solution of the utility model, a first ball valve and a second ball valve are fixedly connected to the liquid inlet pipe and the liquid outlet pipe respectively.
[0011] As a further solution of the utility model, a liquid guiding block is fixedly provided at the lowest point of the spiral ramp, and the top surface of the liquid guiding block located in the cavity is open.
[0012] As a further solution of the utility model, the liquid outlets of the liquid guide block and the liquid outlet pipe are both connected to a water tank fixedly connected to the top surface of the base, and a liquid blocking plate is hingedly provided on the inner wall of the water tank at the liquid outlet of the liquid guide block.
[0013] The beneficial effects of the utility model are as follows:
[0014] Open the first ball valve at the liquid inlet pipe, inject cold water into the spiral tube, and then close the first ball valve. During the curing process, the remaining high-temperature steam heats the cold water in the spiral tube in the cavity. When the temperature of the steam continues to decrease, it gradually condenses into water droplets, falls on the spiral ramp, and then guides to the liquid guide block. At the same time, the water droplets generated or condensed during the curing process can be guided by the arc bottom wall to lead the curing cavity through the liquid outlet groove and enter the spiral ramp of the cavity. After flowing into the liquid guide block, they converge at the rear of the liquid blocking plate and can be opened to flow into the water tank. The second ball valve can be opened to converge the heated water into the water tank, so that the waste heat is utilized without causing waste of resources. At the same time, the water in the water tank is heated to a certain temperature in the next process to reduce the heating time, which not only speeds up efficiency but also reduces resource utilization.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, a concrete block autoclave curing waste heat recovery and utilization device comprises a base 1, a curing box 2 is fixed on the top surface of the base 1, the curing box 2 is divided into a cavity 4 and a curing cavity 5 by a partition 3, a spiral tube 6 is fixed in the cavity 4, a spiral ramp 7 is fixed at the bottom end of the cavity 4, and a liquid outlet trough 8 connected to the cavity 4 is opened at the bottom end of the curing cavity 5, the liquid outlet trough 8 can be used for liquid generated during the curing process to flow into the spiral ramp 7 in the cavity 4, and the spiral ramp 7 can be gradually lowered to guide the water to avoid being retained in the cavity 4.
[0022] In this embodiment, the bottom wall of the curing chamber 5 is arc-shaped and guided into the cavity 4 . The arc-shaped bottom wall can facilitate the generated water to flow into the cavity 4 .
[0023] In this embodiment, the height of the liquid outlet trough 8 is higher than the highest point of the spiral ramp 7, so that the spiral ramp 7 can receive and discharge all the water.
[0024] In this embodiment, a liquid inlet pipe 9 and a liquid outlet pipe 10 are fixedly connected to the liquid inlet end and the liquid outlet end of the spiral tube 6 respectively. The liquid inlet pipe 9 replenishes water in the spiral tube 6, and the liquid outlet pipe 10 discharges the heated water.
[0025] In this embodiment, a first ball valve 11 and a second ball valve 12 are fixedly connected to the liquid inlet pipe 9 and the liquid outlet pipe 10 respectively, and water replenishment and drainage operations can be performed by manually operating the first ball valve 11 and the second ball valve 12 .
[0026] In this embodiment, a liquid guiding block 13 is fixedly provided at the lowest point of the spiral ramp 7. The top surface of the liquid guiding block 13 located in the cavity 4 is open. The opening of the top surface of the liquid guiding block 13 allows water on the spiral ramp 7 to fall into the liquid guiding block 13.
[0027] In this embodiment, the liquid outlet of the liquid guiding block 13 and the liquid outlet pipe 10 are both connected to a water tank 14 fixedly connected to the top surface of the base 1. A liquid blocking plate 15 is hinged on the inner wall of the water tank 14 at the liquid outlet of the liquid guiding block 13. The liquid guiding block 13 is tilted as a whole, which is more conducive to the flow of water inside. The liquid blocking plate 15 can be flipped open to allow the internal water to flow into the water tank 14.
[0028] It should be noted that the utility model is a waste heat recovery and utilization device for autoclaving and curing of concrete blocks. When in use, the first ball valve 11 at the liquid inlet pipe 9 is opened to inject cold water into the spiral tube 6, and then the first ball valve 11 is closed. The high-temperature steam remaining in the curing process heats the cold water in the spiral tube 6 in the cavity 4. When the temperature of the steam continues to decrease, it gradually condenses into water droplets and falls on the spiral ramp 7 and then guides to the liquid guide block 13. At the same time, the water droplets generated or condensed in the curing process can be guided by the arc bottom wall through the liquid outlet groove 8 to guide the curing cavity 5 into the spiral ramp 7 of the cavity 4. After flowing into the liquid guide block 13, it converges at the rear of the liquid blocking plate 15 and can flow into the water tank 14 when it is opened. The second ball valve 12 can be opened to converge the heated water into the water tank 14, so that the waste heat is utilized without causing waste of resources. At the same time, the water in the water tank 14 is heated to a certain temperature in the next process to reduce the heating time, which not only speeds up the efficiency but also reduces the utilization of resources.
