Description

Technical Field

[0001] The invention belongs to the field of energy conservation and environmental protection, and in particular relates to an intelligent energy-saving maintenance system for prefabricated concrete products. Background Art

[0002] The autoclave is a large pressure vessel with a large volume and heavy weight. It has a wide range of uses and is widely used in the autoclave curing of concrete prefabricated products such as aerated concrete blocks and concrete pipe piles. It is a very important industrial equipment.

[0003] However, in the use of the existing autoclave, concrete prefabricated products such as aerated bricks, wall panels, prefabricated piles, etc. are stacked on a trolley and put into the autoclave for autoclave curing. After stacking, the shape is mostly rectangular, so there are many cavities in the autoclave. On the one hand, it causes a waste of space in the autoclave, and due to the existence of the cavity, the curing process of the concrete prefabricated products in the autoclave needs to consume more steam, and the steam dissipates heat quickly through the autoclave body, and more high-temperature steam and high-temperature condensed water will be generated and discharged, resulting in a waste of heat and water resources; on the other hand, after completing one curing, the steam and condensed water in the autoclave have been discharged, and the heat loss is large. The initial temperature in the autoclave is relatively low. The next time the concrete prefabricated products enter the autoclave, they need to be heated from a low temperature, consuming more steam, and the curing time is correspondingly longer, which prolongs the turnover time of the autoclave and seriously reduces the production utilization efficiency of the autoclave.

[0004] In addition, due to the large temperature difference between the inside and outside of the autoclave, if the temperature is not cooled down for a period of time, the prefabricated concrete product is prone to cracking after leaving the autoclave. In the prior art, in order to prevent the prefabricated concrete product from cracking, some methods are used to extend the cooling time of the prefabricated concrete product in the autoclave, which will further extend the turnover time of the autoclave and reduce the production efficiency of the autoclave; or, the method of manually covering the prefabricated concrete product with materials such as oilcloth is used to achieve simple insulation, but this method does not have a good insulation effect and also increases the labor intensity of the producer.

[0005] This shows that the prior art needs to be further improved and enhanced. Summary of the invention

[0045] like Figure 1-11 As shown, the present invention provides an intelligent energy-saving curing system for prefabricated concrete products, which includes an autoclave 10, a steam generating device 20, and a plurality of water storage tanks 11. The water storage tanks 11 are arranged inside the autoclave 10 and connected to the inner wall of the autoclave 10. The side of the water storage tank 11 facing the prefabricated concrete products in the autoclave and the inner wall of the autoclave 10 form a curing channel 12. An autoclave track 13 is arranged at the bottom of the curing channel 12. The autoclave track 13 is used to carry and transport the prefabricated concrete products. An opening is arranged at the top of the water storage tank 11 to collect high-temperature condensed water generated in the autoclave 10.

[0046] Continue to refer to Figure 2 and Figure 3 , and also includes a terminal curing unit, which includes a heat preservation chamber 31 and a heat exchange control component (not shown in the figure). The heat preservation chamber 31 is arranged at the outlet of the autoclave 10. An outer track 313 that cooperates with the inner track 13 is provided in the heat preservation chamber 31. The outer track 313 can receive the concrete prefabricated product in the autoclave 10. An inlet is provided on the side of the heat preservation chamber 31 facing the outlet of the autoclave 10. The concrete prefabricated product and the high-temperature steam in the autoclave 10 can enter the heat preservation chamber 31 through the outlet. The interior of the heat preservation chamber 31 can exchange heat with the outside to reduce the internal temperature of the heat preservation chamber 31; the heat exchange control component is connected to the heat preservation chamber 31, and the heat exchange control component is used to control the temperature reduction rate in the heat preservation chamber 31.

[0047] The provision of the water storage tank 11 in the autoclave, on the one hand, reduces the useless cavity in the autoclave, improves the space utilization rate in the autoclave 10, and reduces the waste of steam during the curing process; on the other hand, the water storage tank 11 can collect the high-temperature condensed water generated in the autoclave 10 through the opening at the top thereof and temporarily store it, thereby playing a role in storing heat, improving the initial curing temperature of the prefabricated concrete product in the autoclave 10, saving steam usage and energy consumption, and also reducing the time-consuming curing process and the turnover of the autoclave 10, thereby improving the production utilization efficiency of the autoclave 10.

[0048] The setting of the terminal insulation unit reduces the temperature difference of the environment of the concrete prefabricated products before and after leaving the autoclave, avoiding the shrinkage and cracking of the concrete prefabricated products due to excessive temperature difference. In addition, the insulation chamber 31 can receive the high-temperature steam in the autoclave 10, make full use of the heat carried by the high-temperature steam, improve the heat utilization efficiency, and save energy; the setting of the track 13 inside the autoclave and the track 313 outside the autoclave and the coordination between the two improve the transportation efficiency of the concrete prefabricated products, thereby improving the overall production efficiency. In addition, the setting of the heat exchange control component can improve the adaptability of the terminal maintenance unit to the cooling conditions required by different types of concrete prefabricated products, improve the maintenance effect, and expand the scope of application of the terminal insulation unit.

[0049] It should be noted that the present invention does not specifically limit the type and structure of the steam generating device 20. As a preferred embodiment of the present invention, the steam generating device 20 is selected as a boiler or power plant pipeline steam. Of course, other equipment and devices may also be used.

[0050] Furthermore, if Figure 2 As shown, the insulation chamber 31 in the present application includes an insulation chamber frame 311 and one or more temperature control layers 312; the one or more temperature control layers 312 cover the insulation chamber frame 311 to form the insulation chamber 31. It should be understood that the present invention does not specifically limit the material of the temperature control layer 312 and the connection method between the temperature control layer 312 and the insulation chamber frame 311. For example, the temperature control layer 312 is a flexible insulation material, which is covered on the insulation chamber frame 311 and fixed by hanging a counterweight; it can also be a rigid insulation material, which is connected to the insulation chamber frame 311 by buckles or screws.

[0051] The temperature control layer 312 is covered on the insulation chamber frame 311, and the insulation layer and the insulation chamber frame 311 are detachably connected, with a simple structure and convenient construction, which greatly improves the assembly efficiency of the insulation chamber 31 and saves time, manpower and material resources.

[0052] As a preferred implementation of the embodiment of the present invention, Figure 2As shown, the temperature control layer 312 is a layer of thermal insulation tarpaulin, which completely covers the thermal insulation room frame 311. A counterweight (not shown in the figure) is hung on the thermal insulation tarpaulin to tighten the thermal insulation tarpaulin so that the thermal insulation tarpaulin and the thermal insulation room frame 311 fit tightly.

[0053] It should be noted that the present invention does not impose any specific restrictions on the structure and shape of the heat exchange control element, and it can adopt any one of the following examples:

[0054] In one embodiment, continue to refer to Figure 2 The temperature control layer 312 also serves as a heat exchange control element. By changing the number of layers of the temperature control layer 312, the heat exchange rate between the inside of the heat preservation chamber 31 and the outside is adjusted, thereby achieving different heat preservation and cooling effects. This solution has a simple structure and is easy to operate. When the maintenance requirements are not high, it can not only ensure the maintenance effect, but also greatly save the manpower and material resources required for production and improve production efficiency.

[0055] As a preferred embodiment of the present invention, Figure 4 As shown, the heat exchange control component includes a temperature sensor 321, a heat exchange pipe 322, a fan 323 and a controller 324; one end of the heat exchange pipe 322 is connected to the outside, and the other end is connected to the inside of the insulation chamber 31, and the fan 323 is arranged on the heat exchange pipe 322; the temperature sensor 321 is arranged in the insulation chamber 31; the controller 324 is electrically connected to the fan 323, and the temperature sensor 321 is electrically connected to the controller 324. The temperature sensor 321 is used to monitor the temperature in the insulation chamber 31 and transmit the signal to the controller 324. The controller 324 is used to receive and process the signal of the temperature sensor 321, and control the closing and starting of the heat exchange pipe 322 and the fan 323.

[0056] The setting of the temperature sensor 321 can accurately detect the temperature of the insulation chamber 31. When the maintenance requirements are high, through the cooperation of the temperature sensor 321, the heat exchange pipe 322, the fan 323 and the controller 324, the heat exchange rate between the inside of the insulation chamber 31 and the outside world can be fine-controlled and fine-tuned, thereby achieving better maintenance effects.

[0057] Furthermore, if Figure 5 As shown, the concrete prefabricated product intelligent energy-saving maintenance system in the present invention is also provided with a residual steam recovery unit, which includes a steam exhaust part 41, a steam exhaust pipe 42, an exhaust valve 43 and a residual steam recovery box 44. It should be understood that the present invention does not specifically limit the structure, connection method, etc. of the steam exhaust part 41, the steam exhaust pipe 42, the exhaust valve 43 and the residual steam recovery box 44, and the following exemplary implementation methods can be adopted;

[0058] Specifically, continue to refer to Figure 5A residual steam recovery hole 14 is opened on one side of the autoclave wall of the autoclave 10, one end of an exhaust pipe 42 is connected to the residual steam recovery hole 14, and the other end is connected to a residual steam recovery box 44, an exhaust part 41 is arranged on the exhaust pipe 42, and an emptying valve 43 is arranged on the exhaust pipe 42; the residual steam recovery box 44 is respectively connected to an external water source and a steam generating device 20, and the residual steam recovery box 44 can supply water to the steam generating device 20.

[0059] In the actual production process, for production needs and safety needs, although the high-pressure steam in the autoclave has been transferred out for reuse before opening the autoclave 10, it is still necessary to empty the remaining low-pressure and high-temperature steam in the autoclave. The residual steam recovery component in the present application, after opening the exhaust valve 43, uses the exhaust part 41 to provide power, collects the residual steam in the autoclave through the residual steam recovery hole 14 and the exhaust pipe 42, and transports the residual steam in the autoclave to the residual steam recovery box 44, and uses the heat carried by the residual steam in the autoclave to heat the cold water in the residual steam recovery box 44 through the heat exchange pipe, thereby saving the energy required for the steam generating device 20 to generate steam. Compared with the prior art of directly discharging the residual steam in the autoclave to the outside, the setting of the residual steam recovery unit effectively recycles and utilizes the heat carried by the residual steam in the autoclave, reducing energy consumption.

[0060] As a preferred implementation in this embodiment, the exhaust component 41 in the residual steam recovery unit is selected as the fan 323. Of course, other components or equipment may also be used, and the present invention does not make specific limitations on this.

[0061] Furthermore, if Figure 6-Figure 8 As shown, the prefabricated concrete intelligent energy-saving maintenance system in the present invention is further provided with a supplementary steam component, including a supplementary steam pipeline 51 and a supplementary steam valve 52, and the supplementary steam valve 52 is arranged on the supplementary steam pipeline 51. It should be noted that the present invention does not specifically limit the arrangement of the supplementary steam pipeline 51, and the following exemplary implementations can be adopted:

[0062] In a specific example, Figure 6 As shown, one end of the supplementary steam pipe 51 is communicated with the exhaust member 41 , and the other end is communicated with the interior of the insulation chamber 31 .

[0063] In another specific example, one end of the supplementary steam pipe 51 is connected to the steam generating device 20, and the other end is connected to the interior of the insulation chamber 31. As a preferred implementation of the embodiment of the present invention, Figure 8 As shown, one end of the supplementary steam pipe 51 is communicated with the exhaust component 41 and the steam generating device 20 respectively, and the other end is communicated with the interior of the insulation chamber 31 .

[0064] By providing a steam supplement component, high-temperature residual steam can be added to the interior of the insulation chamber 31 at any time, so that the heat exchange rate between the interior of the insulation chamber 31 and the outside is more controllable, thereby obtaining a more ideal maintenance effect.

[0065] Furthermore, if Figure 1 As shown, an overflow pipe (not shown in the figure) is also provided in the autoclave 10, an overflow port 111 is opened on the upper part of the water storage tank 11, and the overflow pipe is connected to the overflow port 111; the overflow pipe is laid along the inner wall of the autoclave 10 to the bottom of the autoclave cavity.

[0066] The overflow port 111 and the overflow pipe are arranged to prevent the high-temperature condensed water in the water tank 11 from overflowing due to excessive water level or boiling and splashing due to high temperature, ensuring that production personnel will not be splashed or scalded when inspecting and repairing the autoclave. In addition, the overflow pipe is laid along the inner wall of the autoclave 10 all the way to the bottom of the autoclave cavity, so that the heat carried by the high-temperature condensed water is more evenly distributed in the maintenance channel 12, which helps to improve the maintenance effect.

[0067] Furthermore, if Fig. 9 and Fig.10 As shown, the insulation room rack 311 includes multiple main support rods, and a cross-link is arranged between every two adjacent main support rods; the cross-link is provided with a link retraction position, and the link retraction positions on adjacent cross-links are in opposite directions, so that when the main support rods are retracted into place, the link retraction positions of the adjacent cross-links are aligned with each other; the cross-link is rotatably connected to the main support rod.

[0068] The arrangement of the cross-links enables the insulation chamber frame 311 to be retracted, which makes the erection and disassembly of the insulation chamber 31 more convenient and quicker on the one hand; on the other hand, the retractable insulation chamber frame 311 facilitates the handling of concrete prefabricated products by hoisting equipment such as cranes or lifting equipment, thereby improving production efficiency.

[0069] It should be noted that the present invention does not specifically limit the structure of the insulation room frame 311 and the cross connecting rod. Fig. 9 or Fig.10 The structure shown can also be used in other structures.

[0070] Furthermore, if Fig.11 As shown, the concrete prefabricated product intelligent energy-saving maintenance system in the present invention also includes a condensate collection box 60 and a sedimentation tank (not shown in the figure), and the condensate collection box 60 is provided with a collection hole 61 and a discharge hole 62; the autoclave 10 is provided with a sewage outlet 15, and the high-temperature condensate in the autoclave 10 enters the condensate collection box 60 through the sewage outlet 15 and the collection hole 61; the discharge hole 62 is connected to the sedimentation tank, and the high-temperature condensate is finally discharged into the sedimentation tank through the discharge hole 62.

[0071] Further, refer to Fig.11 A heat exchange tube 63 is provided in the condensate collection box 60; one end of the heat exchange tube 63 is connected to an external water source, and the other end is connected to the steam generating device 20 or other water loads.

[0072] The arrangement of the condensate collection box 60 and the heat exchange tube 63 therein can effectively recover the heat carried by the high-temperature condensate and use it to heat domestic water or boiler raw water, thereby saving energy consumption.

[0073] It should be understood that the present invention does not specifically limit the shape and structure of the condensate collection box 60 and the heat exchange tube 63. For example, as a preferred example of the embodiment of the present invention, continue to refer to Fig.11 As shown, the heat exchange tube 63 is arranged in a spiral shape, so that the water from the external water source has a longer flow path in the heat exchange tube 63 and has a better heat exchange effect. Of course, the heat exchange tube 63 can also adopt other structural forms.

[0074] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and the points repeated in each embodiment are the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0075] The above is only an example of the implementation of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
