Description

Technical Field

[0001] The present disclosure relates to the technical field of concrete production, and in particular to a refrigeration system for a concrete mixing plant. Background Art

[0002] In the related art, when processing concrete, the processing temperature of concrete has a significant impact on the quality of the concrete. Therefore, in high-temperature weather or hot areas, the mixing plant often needs to be refrigerated.

[0003] There are currently two common refrigeration treatments for mixing plants: the first is to use an ammonia refrigeration system. However, ammonia is a major hazard source, and inspection and approval are difficult and time-consuming. At the same time, setting up an ammonia refrigeration workshop requires on-site construction, which takes a long time. The pressure pipes of the refrigeration system need to be constructed and tested on-site, making quality control difficult. After the project is completed, the equipment is difficult to dismantle and the reuse rate is low. The operation and maintenance of the equipment requires experienced professionals, and the operation and maintenance costs are high. The second method is to use a Freon refrigeration system. The refrigeration units of the Freon refrigeration system are distributed, occupying a large area, and the pipe connection distance increases, which will increase the construction cost. Furthermore, in related technologies, the cooling temperature of the refrigeration system for the mixing plant is relatively fixed, while the processing environment temperature changes all the time, making the cooling of the mixing plant more inconvenient.

[0004] To solve the above problems, an embodiment of the present disclosure provides a refrigeration system for a mixing building.

[0047] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent identical or similar structures, and thus their detailed descriptions will be omitted. Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0048] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0049] Based on some problems existing in the refrigeration system of the prior art, the embodiments of the present disclosure provide a refrigeration system for a mixing plant, which can reduce the installation, transportation and use costs of the refrigeration system and realize flexible refrigeration of the mixing plant.

[0050] See also Figure 1 、 Figure 2 The refrigeration system 2 includes a refrigeration building 21, multiple installation boxes 22, a first refrigeration module 23, a second refrigeration module 24 and a third refrigeration module 25; the refrigeration building 21 is arranged on one side of the mixing building 1, and the refrigeration building 21 has multiple layers; multiple installation boxes 22 are arranged on different layers of the refrigeration building 21; the mixing building 1 has a storage layer 13 and a batching device 11; the first refrigeration module 23 and the second refrigeration module 24 are arranged on different installation boxes 22; wherein, the first refrigeration module 23 is used to pass a medium with a first temperature range into the batching device 11; the second refrigeration module 24 is used to pass a medium with a second temperature range into the batching device 11; the third refrigeration module 25 is used to pass a medium with a third temperature range into the storage layer 13.

[0051] In the embodiment of the present disclosure, when constructing the refrigeration system 2, a refrigeration building 21 can be constructed on one side of the mixing building 1; the refrigeration building 21 has multiple layers, and the installation box 22 is installed on different layers of the refrigeration building 21 (the first refrigeration module 23, the second refrigeration module 24 and part of the third refrigeration module 25 are transported and installed using the installation box 22 as a carrier); when the mixing building 1 is cooled, the first refrigeration module 23 can pass a medium with a first temperature range into the batching device 11; the second refrigeration module 24 can pass a medium with a second temperature range into the batching device 11; the third refrigeration module 25 can pass a medium with a third temperature range into the batching device of the storage layer 13, and the cooled material enters the batching device 11, thereby realizing the refrigeration treatment of the mixing building 1. At the same time, the first refrigeration module 23, the second refrigeration module 24 and part of the third refrigeration module 25 use the installation box 22 as a carrier. When transporting the first refrigeration module 23, the second refrigeration module 24 and part of the third refrigeration module 25 (when cooling different mixing buildings 1, it is only necessary to install the first refrigeration module 23, the second refrigeration module 24 and the third refrigeration module 25 with the installation box 22 as a carrier on one side of the mixing building 1), the installation box 22 can be transported, thereby facilitating the installation and transportation of the refrigeration system 2.

[0052] It can be understood that in the embodiment of the present disclosure, the first temperature interval, the second temperature interval and the third temperature interval represent different temperatures.

[0053] As an example, the third temperature range is greater than the first temperature range; the first temperature range is greater than the second temperature range. In this way, media corresponding to different temperature ranges can be introduced into the batching device 11 according to different requirements of the mixing plant 1.

[0054] As another example, the medium corresponding to the first temperature range may be cold water; the medium corresponding to the second temperature range may be flake ice; and the medium corresponding to the third temperature range may be cold air.

[0055] As another example, the refrigeration building 21 may have a length of 15 m, a width of 6 m, and a height of 33 m.

[0056] In some embodiments of the present disclosure, the third refrigeration module has an aggregate refrigeration sub-module 253, wherein along the height direction of the refrigeration building 21, from the top to the bottom of the refrigeration building 21, the second refrigeration module 24, the aggregate refrigeration sub-module 253 and the first refrigeration module 23 are arranged in sequence.

[0057] In some embodiments of the present disclosure, see Figure 2, along the height direction of the mixing tower 1, from the top to the bottom of the mixing tower 1, the mixing tower 1 includes a feed layer 12, a storage layer 13, a weighing layer 14, a mixing layer 15 and a discharge layer 16 which are sequentially connected; wherein the feed layer 12 is configured to transport materials into the storage layer 13. In some embodiments, sand and coarse aggregate can be fed into the storage layer 13 by a belt conveyor. It should be noted that belt conveyors are a technical field well known to those skilled in the art and will not be described in detail in this application. The storage layer 13 is configured to store materials input by the feed layer 12. For example, the storage layer 13 can store large stones, medium stones, and small stones. The weighing layer 14 is configured to weigh and proportion the materials entering the storage layer 13 with the remaining materials, and the proportioning device 11 is located in the weighing layer 14. It is understandable that the weighing layer 14 is provided with a weighing mechanism, which can weigh the coarse aggregate, sand, admixture and water in the storage layer 13 according to the set ratio, and can also transport the weighed materials into the mixing layer 15. It should be noted that the weighing mechanism is well known to those skilled in the art, and will not be described in detail in this application. The mixing layer 15 is configured to mix and stir the various materials after weighing; the discharging layer 16 is configured to output the mixed materials, and the mixed materials are output by the discharging layer 16 and then transported to the concrete tank truck for loading. Furthermore, in the embodiment of the present disclosure, the temperature of the concrete output by the discharging layer 16 can be used to guide the refrigeration operation of the first refrigeration module 23, the second refrigeration module 24 and the third refrigeration module 25.

[0058] As an example, the storage layer 13 has four coarse aggregate bins, wherein the four coarse aggregate bins store large stones, medium stones, and small stones respectively. Further, large stones can be stored in two coarse aggregate bins respectively.

[0059] As another example, four groups of centrifugal blowers 252 and air coolers 251 are correspondingly provided for the four coarse aggregate bins, and each group of centrifugal blowers 252 and air coolers 251 is independent of each other. In some embodiments of the present disclosure, the first refrigeration module 23 includes a water tank 231 and a chiller 232; the water tank 231 is provided on one side of the refrigeration building 21; the chiller 232 is provided on the mounting box 22, the chiller 232 is connected to the water tank 231, and the outlet end of the chiller 232 is connected to the batching device 11. Specifically, when the first refrigeration module 23 is in operation, the chiller 232 can pump the normal temperature water in the water tank 231 into the interior of the chiller 232, and the normal temperature water is cooled by the chiller 232. The cooled water is then passed into the batching device 11, thereby cooling the material in the batching device 11.

[0060] As an example, the normal temperature water in the water tank 231 can be reduced from 28° C. to 5° C. by the chiller 232 .

[0061] As another example, the chiller 232 may include a screw compressor, an evaporative condenser, a heat exchanger, an electronic control system, a water pump, and a piping system (not specifically shown in the drawings of this application). It should be noted that the chiller 232 is a technology well known to those skilled in the art, and this application does not elaborate on its specific structure.

[0062] In some embodiments of the present disclosure, see Figure 2 The second refrigeration module 24 includes a flake ice machine 241, an ice storage bin 242, and a conveying mechanism 243. Both the flake ice machine 241 and the ice storage bin 242 are mounted on the mounting housing 22, with the output end of the flake ice machine 241 communicating with the inlet end of the ice storage bin 242. The conveying mechanism 243 is connected to the mounting housing 22 and is used to deliver the flake ice to the batching device 11. When the second refrigeration module 24 cools the batching device 11, the flake ice machine 241 first transfers the produced flake ice to the ice storage bin 242 for storage. The flake ice in the ice storage bin 242 is then delivered to the batching device 11 via the conveying mechanism 243, thereby cooling the batching device 11.

[0063] As an example, the conveying mechanism 243 may include a belt conveyor. It should be noted that, in some embodiments, the conveying mechanism 243 may be other structures, which will not be described in detail in this application.

[0064] As an example, the flake ice machine 241 may include an evaporative condenser, a flake ice maker, a compressor, and a control system (not specifically shown in the drawings of this application).

[0065] Further, in the remaining embodiments, see Figure 2The second refrigeration module 24 further includes a pneumatic weighing hopper 244; the pneumatic weighing hopper 244 is connected to the mounting box 22, the inlet end of the pneumatic weighing hopper 244 is connected to the outlet end of the ice storage bin 242, and the outlet end of the pneumatic weighing hopper 244 is located directly above the conveying mechanism 243. Specifically, the flake ice in the ice storage bin 242 is delivered to the pneumatic weighing hopper 244. The pneumatic weighing hopper 244 determines the weight of the flake ice delivered from the ice storage bin 242 based on the temperature of the concrete delivered from the discharge layer 16 (for example, if the temperature of the concrete delivered from the discharge layer 16 is too high, the batching device 11 needs to be cooled, which means that a larger amount of flake ice is needed; similarly, if the temperature of the concrete delivered from the discharge layer 16 is too low, the batching device 11 needs to be cooled, which means that a smaller amount of flake ice is needed). The pneumatic weighing hopper 244 then delivers the weighed flake ice to the conveying mechanism 243, which delivers the flake ice to the batching device 11. The pneumatic weighing hopper 244 and the conveying mechanism 243 are arranged in coordination with each other. After the pneumatic weighing hopper 244 completes weighing the flake ice, the conveying mechanism 243 quickly passes the flake ice into the batching device 11, which can shorten the distance for conveying the flake ice and reduce the loss of flake ice during transportation, thereby ensuring accurate cooling in the batching device 11.

[0066] In some embodiments of the present disclosure, see Figure 2 The storage layer 13 is connected to the feeding area 131, the cooling area 132 and the storage area 133 in sequence along its height direction; the third refrigeration module 25 also includes an air cooler 251 and a centrifugal blower 252; the cooling area 132 has a cooling bottom and a cooling top; the inlet end of the centrifugal blower 252 is connected to the aggregate refrigeration sub-module 253, the aggregate refrigeration sub-module 253 is used to provide a cold source to the centrifugal blower 252, and the output end of the centrifugal blower 252 is connected to the cooling bottom for blowing cold air into the cooling bottom; the inlet end of the air cooler 251 is connected to the cooling top, and the output end of the air cooler 251 is connected to the inlet end of the centrifugal blower 252.

[0067] Specifically, the refrigeration mechanism of the third refrigeration module 25 is as follows: the aggregate refrigeration submodule 253 produces refrigerant, the aggregate refrigeration submodule 253 provides a cold source to the centrifugal blower 252, the centrifugal blower 252 generates cold air, the generated cold air is sent into the cooling bottom, and the aggregate flow in the reverse storage layer 13 passes through the aggregate to absorb heat and heat up, and then is sent out from the cooling top. The air flowing out of the cooling top enters the air cooler 251 for cooling, and the cooled cold air is continued to be introduced into the cooling bottom by the centrifugal blower 252 for the next cooling cycle. The aggregate in the storage layer 13 is continuously circulated and cooled in the cold air, and enters the storage area 133 after the temperature drops to the required temperature. In some embodiments of the present disclosure, the refrigeration system 2 also includes a control module (not specifically shown in this application); the control module is used to respond to a first signal so that the first refrigeration module 23 passes a medium with a first temperature range into the dosing device 11; the control module is used to respond to a second signal so that the second refrigeration module 24 passes a medium with a second temperature range into the dosing device 11; the control module is used to respond to a third signal so that the third refrigeration module 25 passes a medium with a third temperature range into the dosing device 11.

[0068] As an example, a worker monitors the temperature of concrete discharged from the discharge layer 16. When the temperature exceeds a preset temperature, the worker operates the control module, which instructs the corresponding refrigeration module to operate, thereby cooling the batching device 11. Specifically, when the worker detects that the concrete temperature is significantly higher than the preset temperature, the worker operates the control module, which responds to a second signal to cause the second refrigeration module 24 to introduce a medium within a second temperature range into the batching device 11. When the worker detects that the concrete temperature is slightly higher than the preset temperature, the worker operates the control module, which responds to a third signal to cause the third refrigeration module 25 to introduce a medium within a third temperature range into the storage layer 13. When the worker detects that the concrete temperature exceeds the preset temperature and that the third refrigeration module 25 has difficulty cooling the storage layer 13, the worker operates the control module, which responds to a first signal to cause the first refrigeration module 23 to introduce a medium within the first temperature range into the batching device 11. In this manner, the control module sends refrigeration to the corresponding refrigeration module, thereby cooling the batching device 11.

[0069] It can be understood that, in this example, the first signal, the second signal and the third signal are signals transmitted by the control module when the staff presses the corresponding button control module, and this example will not elaborate on this.

[0070] In some embodiments of the present disclosure, the control module is configured to respond to the fourth signal to enable at least two refrigeration modules among the first refrigeration module 23 , the second refrigeration module 24 and the third refrigeration module 25 to introduce corresponding media into the batching device 11 .

[0071] It is understood that the fourth signal in this embodiment refers to a signal corresponding to pressing at least two of the first cooling module 23, the second cooling module 24, and the third cooling module 25. For example, the fourth signal is a signal that controls the operation of the first cooling module 23 and the second cooling module 24 simultaneously; the fourth signal is a signal that controls the operation of the first cooling module 23 and the third cooling module 25 simultaneously; the fourth signal is a signal that controls the operation of the second cooling module 24 and the third cooling module 25 simultaneously; and the fourth signal is a signal that controls the operation of the first cooling module 23, the second cooling module 24, and the third cooling module 25 simultaneously.

[0072] Furthermore, the control module may include a temperature sensor and a processor. The temperature sensor is arranged at the discharge layer 16. When the concrete is output from the discharge layer 16, the temperature sensor can detect the temperature of the concrete. After detecting the temperature, the temperature sensor transmits the temperature value to the processor. The processor compares the detected temperature with the preset temperature and sends a corresponding signal to the corresponding refrigeration module (the first refrigeration module 23, the second refrigeration module 24 and the third refrigeration module 25) to guide the refrigeration module to perform the cooling operation on the batching device 11.

[0073] In some embodiments of the present disclosure, aggregate cooling submodules 253 are installed within the installation housing 22. As an example, multiple aggregate cooling submodules 253 can be arranged, with some installed on the same floor as the first cooling module 23. This allows for efficient utilization of the space within the refrigeration building 21 and maximizes the space utilization of the refrigeration system. The aggregate cooling submodules 253 are used to cool materials entering the storage layer 13. Multiple groups of aggregate cooling submodules 253 are installed within the installation housing 22, using the installation housing 22 as a carrier for ease of installation and transport.

[0074] It is understandable that the aggregate needs to be insulated before entering the mixing plant 1. In the related art, when insulating the aggregate, a pre-cooling bin is required. This will increase the transfer process of the aggregate and also result in a large floor space under limited site conditions. Based on this, the present application provides multiple groups of aggregate cooling submodules 253, which are arranged in the installation box 22, using the installation box 22 as a carrier to facilitate their installation and transportation.

[0075] The above-mentioned refrigeration system 2 is actually applied in the mixing building 1 project. The average temperature at the location of the mixing building 1 is between 28 and 29°C, and the preset temperature of the concrete is 16°C. This refrigeration system 2 adopts a combination of the first refrigeration module 23, the second refrigeration module 24 and the third refrigeration module 25 to achieve pre-cooling of the mixing building 1.

[0076] In summary, the refrigeration system 2 for the mixing plant 1 disclosed in this application utilizes a mounting box 22, making it easy to install and transport for use in a variety of harsh working environments. This innovative design transforms the cumbersome on-site construction of traditional refrigeration measures into a fully portable, complete refrigeration system. The entire system is manufactured in a modern factory using a specialized, complete-unit production process, ensuring the airtightness and cleanliness of the refrigeration system 2, laying a solid foundation for long-term, reliable operation. The mounting boxes 22 are arranged in layers within the refrigeration building 21, minimizing footprint and increasing reuse, reducing construction costs and secondary investment.

[0077] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.
