Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery systems in concrete pole manufacturing, and more specifically, to a circulation system for recovering waste heat during the manufacturing process of concrete poles for curing. Background Technology

[0002] The manufacturing process of concrete poles typically consumes a large amount of energy for production processes such as centrifugal molding and steam curing. The steam curing process is intended to accelerate the hardening of concrete and improve the strength and performance of concrete poles. However, most existing steam curing methods directly release large amounts of steam and heat, which are then discharged outdoors through pipes. This not only results in a significant waste of energy but also causes thermal pollution to the environment.

[0003] With rising energy costs and increasingly stringent environmental regulations, effectively recovering and utilizing waste heat from the manufacturing process of concrete poles to achieve energy recycling has become a pressing issue in this field. Therefore, we propose a recycling system for recovering waste heat during the manufacturing process of concrete poles for curing purposes. Utility Model Content

[0004] The purpose of this invention is to provide a recycling system for recovering waste heat during the manufacturing process of concrete poles for curing, in order to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A circulating system for recovering waste heat during the manufacturing process of concrete poles for curing includes a hot gas exhaust pipe. A heat exchange assembly is installed on the hot gas exhaust pipe. The heat exchange assembly includes a heat exchange medium storage tank located on one side of the hot gas exhaust pipe. A first pump body is installed on one side of the heat exchange medium storage tank. The inlet end of the first pump body is connected to the heat exchange medium storage tank via a suction pipe. A spiral heat exchange tube is fixedly installed at the outlet end of the first pump body, located inside the hot gas exhaust pipe. A conveying pipe is fixedly installed at the outlet end of the spiral heat exchange tube, extending out of the hot gas exhaust pipe.

[0007] Preferably, the inlet end of the hot gas exhaust pipe is fixedly installed with a fixed connector, which is fixedly installed at the exhaust end of the external concrete pole manufacturing equipment.

[0008] Preferably, a top cover is hinged to the top surface of the heat exchange medium storage cylinder, and a handle is fixedly installed on the front of the top cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the heat exchange component, uses a first pump body to pump the medium in the heat exchange medium storage cylinder into the spiral heat exchange tube in the hot gas exhaust pipe, absorbing the heat generated during the manufacturing process, and then transferring the heat to the curing tank through the conveying pipe and the serpentine heat exchange tube, realizing the transfer of waste heat from the manufacturing stage to the curing stage, achieving the effect of effectively recovering and utilizing waste heat and reducing energy waste.

[0016] 2. This utility model, by setting support rollers and serpentine heat exchange tubes below them in the curing tank, enables the serpentine heat exchange tubes to be placed stably.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figures 1-4This utility model provides a technical solution: a circulation system for recovering waste heat during the manufacturing process of concrete poles for curing, including a hot gas exhaust pipe 1. A fixed joint 10 is fixedly installed at the air inlet end of the hot gas exhaust pipe 1. The fixed joint 10 is fixedly installed at the exhaust end of the external concrete pole manufacturing equipment, so that the fixed joint 10 can be stably installed at the exhaust end of the external concrete pole manufacturing equipment, allowing the hot gas exhaust pipe 1 to smoothly receive the hot gas generated by the manufacturing equipment, realizing the directional collection of waste heat, and enabling the subsequent waste heat recovery and utilization process to be carried out.

[0028] Specifically, a heat exchange assembly 2 is installed on the hot gas exhaust pipe 1. The heat exchange assembly 2 includes a heat exchange medium storage tank 20 disposed on one side of the hot gas exhaust pipe 1. A first pump body 22 is disposed on one side of the heat exchange medium storage tank 20. The liquid inlet end of the first pump body 22 is connected to the heat exchange medium storage tank 20 through a suction pipe 221. A spiral heat exchange tube 23 is fixedly installed at the liquid outlet end of the first pump body 22. The spiral heat exchange tube 23 is located inside the hot gas exhaust pipe 1. A delivery pipe 24 is fixedly installed at the water outlet end of the spiral heat exchange tube 23, extending out of the hot gas exhaust pipe 1. A serpentine heat exchange tube 25 is fixedly installed at the end of the delivery pipe 24. A return pipe 26 connected to the heat exchange medium storage tank 20 is fixedly installed at the end of the serpentine heat exchange tube 25. A curing tank 3 is provided on one side of the cylinder 20. The serpentine heat exchange tube 25 is located in the curing tank 3. Multiple support rollers 30 arranged at equal intervals are fixedly installed between the left and right side plates of the curing tank 3. The serpentine heat exchange tube 25 is located below the support rollers 30. The first pump body 22 draws the medium from the heat exchange medium storage cylinder 20 through the suction pipe 221 and sends it into the spiral heat exchange tube 23 located in the hot gas discharge pipe 1. The spiral heat exchange tube 23 is spiral in shape, which increases the heat exchange area and efficiently absorbs the heat of the hot gas. Subsequently, the medium is circulated through the conveying pipe 24, the serpentine heat exchange tube 25 and the return pipe 26, so that the heat exchange medium continuously absorbs and transfers heat during the circulation process, realizing the effective transfer of waste heat from the hot gas to the curing process.

[0029] In this embodiment, a top cover 21 is hinged to the top surface of the heat exchange medium storage cylinder 20. A handle 211 is fixedly installed on the front of the top cover 21, which makes it convenient for operators to open the top cover 21 and replenish the heat exchange medium in the cylinder, making the use of the heat exchange medium storage cylinder 20 more convenient.

[0030] Specifically, the end of the suction pipe 221 extends to the bottom wall of the heat exchange medium storage cylinder 20, which facilitates the smoother suction of the heat exchange medium inside the heat exchange medium storage cylinder 20.

[0031] Furthermore, a drain pipe 33 is fixedly installed on the bottom of the curing pool 3, and a valve 34 is fixedly installed on the drain pipe 33. When impurities accumulate in the curing pool 3, the valve 34 can be opened to discharge sewage and impurities through the drain pipe 33, keeping the curing pool 3 clean and making the curing environment more suitable for the curing of concrete poles, thus improving the curing effect.

[0032] In addition, a secondary cylinder 35 is fixedly installed on one side plate of the curing pool 3, and the secondary cylinder 35 is connected to the curing pool 3 through a mesh plate 351; a temperature-controlled electric heating rod 36 is fixedly installed on the inner wall of the secondary cylinder 35, and a temperature sensor 31 is fixedly installed on the inner wall of the curing pool 3. A control host 32 is set on one side of the curing pool 3. The temperature sensor 31 monitors the water temperature in the curing pool 3 in real time. When the residual heat is insufficient and the water temperature is low, the control host 32 can start the temperature-controlled electric heating rod 36. The water temperature is adjusted through the connection between the secondary cylinder 35 and the curing pool 3, so as to achieve precise control of the curing temperature and ensure the curing quality of the concrete pole.

[0033] It is worth noting that a second pump body 37 is installed on one side of the curing pool 3. The inlet end of the second pump body 37 is connected to the auxiliary cylinder 35 through a liquid pipe 371, and the outlet end of the second pump body 37 is connected to the curing pool 3 through a circulation pipe 372. The end of the circulation pipe 372 is located on the opposite side of the auxiliary cylinder 35. When the second pump body 37 is working, it can make the liquid in the curing pool 3 circulate, promote the uniform distribution of heat, make the water temperature in the curing pool 3 more uniform, and ensure that the curing effect of each part of the concrete pole is consistent.

[0034] Finally, it should be noted that the components involved in this utility model, such as the first pump body 22, temperature sensor 31, temperature-controlled electric heating rod 36, control host 32, and second pump body 37, are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0035] In the use of the waste heat recovery and curing circulation system in the concrete pole manufacturing process of this utility model, the fixed joint 10 is first firmly installed at the exhaust end of the concrete pole manufacturing equipment, so that the hot air exhaust pipe 1 can receive the hot air generated by the manufacturing equipment to realize the directional collection of waste heat.

[0036] Next, the first pump body 22 draws the medium from the heat exchange medium storage cylinder 20 through the suction pipe 221 and sends it into the spiral heat exchange tube 23 in the hot gas discharge pipe 1. The spiral heat exchange tube 23 efficiently absorbs the heat of the hot gas and realizes the medium circulation through the delivery pipe 24, the serpentine heat exchange tube 25 and the return pipe 26, transferring the waste heat to the serpentine heat exchange tube 25 in the curing tank 3. The heat in the serpentine heat exchange tube 25 continues to exchange heat with the curing liquid in the curing tank 3, thereby heating the curing liquid in the curing tank 3.

[0037] If heat exchange medium needs to be added, the operator can open the top cover 21 through handle 211; when impurities accumulate in the curing tank 3, open the valve 34 on the drain pipe 33 to discharge sewage and impurities.

[0038] Temperature sensor 31 monitors the water temperature in curing tank 3 in real time. If the residual heat is insufficient, the control host 32 starts the temperature-controlled electric heating rod 36 to heat the water. The second pump body 37 works, drawing liquid from the auxiliary cylinder 35 through the liquid pipe 371 and sending the liquid back to the curing tank 3 through the circulation pipe 372, so that the liquid in the curing tank 3 circulates and the water temperature is more uniform.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
