Description
Technical Field
[0001] The utility model relates to the technical field of plastic product processing, in particular to a high-efficiency air circulation device. Background Art
[0002] Plastic product processing refers to the process of using plastic raw materials to transform them into products with specific shapes and properties through various molding processes such as injection molding, extrusion, blow molding, etc.
[0003] To dissipate the large amounts of heat generated during the plastics processing process and ensure the normal work of workers, existing technology often uses fans to transport air into and out of the workshop to dissipate heat. Specifically, ventilation equipment such as industrial fans, exhaust fans, and negative pressure fans are installed in the workshop. These devices use forced ventilation to quickly remove the hot, muggy air within the workshop while simultaneously introducing fresh air from outside, thereby achieving air circulation and heat dissipation within the workshop.
[0004] The shortcomings of the above-mentioned existing technical solutions are that: during the ventilation process of the plastic processing workshop, the air flow generally blows from one side to the other, and dead corners of air flow are easily formed in the workshop. The air circulation in these areas is poor, resulting in uneven wind distribution, which may cause environmental parameters such as temperature and humidity to get out of control, affecting the quality of plastic processing. Utility Model Content
[0005] The purpose of the utility model is to provide a high-efficiency air circulation device to solve the technical problem in the prior art that in a plastic processing workshop, air flow blows from one side to the other, and dead corners of air flow are easily formed in the workshop. The air circulation in these areas is poor, resulting in uneven wind distribution, which may cause environmental parameters such as temperature and humidity to lose control and affect the quality of plastic processing.
[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions:
[0007] A high-efficiency air circulation device includes a first fan and a second fan arranged on the side of a processing workshop. The device also includes a conveying component for conveying air to the interior of the processing workshop and an output component for outputting air from the interior of the processing workshop to the outside. The conveying component includes a cooling box that is connected to the output end of the first fan, and a cooling device is provided on the cooling box. A first guide pipe is fixedly connected to the cooling box, and a plurality of groups of diversion pipes are fixedly connected to the first guide pipe. Each group of the diversion pipes is fixedly connected to a plurality of groups of output nozzles. The output component includes an output pipe that is connected to the output end of the second fan, and the output pipe is fixedly connected to a second guide pipe at one end away from the second fan. A plurality of collecting pipes are fixedly connected to the second guide pipe, and each group of the collecting pipes is provided with a plurality of groups of air inlets. The collecting pipes are arranged on the top of the processing workshop.
[0008] As a further solution of the present invention: each group of the output nozzles is provided with a regulating valve.
[0009] As a further solution of the present invention: on each group of the collecting pipes, the closer to the second guide pipe, the sparser the distribution of the air inlets, and the farther away from the second guide pipe, the denser the distribution of the air inlets.
[0010] As a further solution of the present invention: each group of the diverter pipes is connected to a first solenoid valve, and each group of the second flow guide pipes is provided with a second solenoid valve.
[0011] As a further solution of the present invention: the cooling device includes a refrigeration compressor, the refrigeration compressor is provided with a cooling pipe, and the cooling pipe is cooperatively arranged inside the cooling box.
[0012] As a further solution of the present invention: each group of the diverter pipes is matched with a corresponding plastic product processing production line.
[0013] As a further solution of the present invention: each group of the diverter pipes is matched with a corresponding collecting pipe.
[0014] Beneficial effects of the utility model:
[0015] 1. When the utility model is in use, the external air flow enters the cooling box under the action of the first fan, and the cooling device cools the air flow through the cooling pipe. The air flow then passes through the first guide pipe and enters the interior of the multi-group manifold pipes, and is output outward through the output nozzles on both sides of each group of manifold pipes, acting on the corresponding plastic product processing production line or on one side of the plastic product processing production line, promoting the flow of air near the processing production line, thereby timely taking the generated heat away from the plastic product processing production line. The plastic product processing production line corresponds to the diversion pipe, thereby ensuring more uniform distribution of cold air and ensuring the air circulation effect.
[0016] 2. When the utility model is in use, the cold air flow continuously delivered by the output nozzle will squeeze the hot air to the top of the processing workshop, thereby facilitating the collection of the hot air. The second fan is started and driven to drive the hot air on the top of the processing workshop into the air inlet, the collecting pipe, the second guide pipe, and the output pipe in sequence, and finally transported to the outside under the action of the second fan, completing the effect of air circulation.
[0017] 3. When using this utility model, some locations on the plastic product processing line generate more heat, such as stamping and thermoforming, while other locations generate less heat, such as feeding and conveying. When in use, the output flow of each set of output nozzles can be adjusted by regulating valves as needed, making it more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figure 1-Figure 3As shown, a high-efficiency air circulation device includes a first fan 2 and a second fan 10 installed on the side of a processing workshop 1. The device also includes a conveying assembly for conveying air into the processing workshop 1 and an output assembly for outputting air from the processing workshop 1. The conveying assembly includes a cooling box 3 that is connected to the output end of the first fan 2. The cooling box 3 is provided with a cooling device 4. The cooling device 4 includes a refrigeration compressor, which is provided with multiple groups of cooling pipes 16. The cooling pipes 16 serve to cool the air. The cooling pipes 16 are installed inside the cooling box 3. First guide pipes 5 are fixedly connected to both sides of the cooling box 3. The first guide pipes 5 are fixedly connected to multiple groups of manifolds 6. Each group of manifolds 6 is compatible with a corresponding plastic product processing production line. The manifolds 6 are installed above the plastic product processing production line. Each group of manifolds 6 is fixedly connected to multiple groups of output nozzles 7. The output ports of the output nozzles 7 face the plastic product processing production line or one side of the plastic product processing line. The external airflow enters the cooling box 3 under the action of the first fan 2, and the cooling device 4 cools the airflow through the cooling pipe 16. The airflow then passes through the first guide pipe 5 and enters the interior of the multi-group manifold 6, and is output outward through the output nozzles 7 on both sides of each group of manifold 6, acting on the corresponding plastic product processing production line, promoting the flow of air near the processing production line, thereby timely taking the generated heat away from the plastic product processing production line.
[0025] The heat output of the plastic product processing line is high at some locations and low at others. Each set of output nozzles 7 is equipped with a regulating valve 8, which can adjust the output flow of each set of output nozzles 7 as needed, making it more flexible and convenient to use.
[0026] The output assembly includes an output pipe 11 that is coupled to the output end of the second fan 10. A second guide pipe 12 is fixedly connected to the end of the output pipe 11 away from the second fan 10. The second guide pipe 12 is located at the top of the processing workshop 1. Multiple sets of headers 13 are fixedly connected to the second guide pipe 12. Each set of headers 13 has multiple sets of air inlets 14. Air from the processing workshop 1 enters the headers 13 through the air inlets 14. The headers 13 are located at the top of the processing workshop 1. The continuously delivered cold airflow pushes the hot air to the top of the processing workshop 1, thereby facilitating its collection. The second fan 10 is started, driving the hot air from the top of the processing workshop 1 to sequentially enter the air inlets 14, the headers 13, the second guide pipe 12, and the output pipe 11. Finally, under the action of the second fan 10, the hot air is transported to the outside world, completing the effect of air circulation.
[0027] Because the second flow conduit 12 is relatively long, the negative pressure difference between the two ends of the second flow conduit 12 can be too large during use, affecting air circulation. On each set of manifolds 13, the air inlets 14 are distributed more sparsely toward the second flow conduit 12 and more densely toward the ends farther from the second flow conduit 12, thereby minimizing the negative pressure difference between the two ends of the second flow conduit 12.
[0028] The processing workshop 1 is equipped with multiple production lines and workshops. Each production line and workshop is equipped with a corresponding shunt pipe 6 and manifold 13. When a production line or workshop needs to be shut down, the corresponding shunt pipe 6 and manifold 13 also need to be closed simultaneously. Each group of shunt pipes 6 is connected to a first solenoid valve 9, and each group of second flow guide pipes 12 is equipped with a second solenoid valve 15. When it is necessary to close a group of shunt pipes 6 and manifold 13, the corresponding first solenoid valve 9 and second solenoid valve 15 can be adjusted to a closed state, thereby adjusting the flow state of the group of shunt pipes 6 and manifold 13.
[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:
[0030] When in use, the external airflow enters the cooling box 3 under the action of the first fan 2, and the cooling device 4 cools the airflow through the cooling pipe 16. The airflow then passes through the first guide pipe 5 and enters the interior of the multi-group manifold 6, and is output outward through the output nozzles 7 on both sides of each group of manifolds 6, acting on the corresponding plastic product processing production line, promoting the flow of air near the processing production line, thereby timely taking the generated heat away from the plastic product processing production line. The plastic product processing production line corresponds to the diversion pipe 6, thereby ensuring more uniform distribution of cold air and ensuring the air circulation effect;
[0031] Some locations in the plastic product processing line generate more heat, such as stamping and thermoforming, while others generate less heat, such as feeding and conveying. During use, the output flow of each set of output nozzles 7 can be adjusted by regulating valve 8 as needed, making it more flexible and convenient to use.
[0032] The cold air continuously delivered by the output nozzle 7 pushes the hot air to the top of the processing workshop 1, thereby facilitating the collection of the hot air. The second fan 10 is started and drives the hot air from the top of the processing workshop 1 to enter the air inlet 14, the collecting pipe 13, the second guide pipe 12, and the output pipe 11 in sequence. Finally, it is transported to the outside under the action of the second fan 10, completing the effect of air circulation.
[0033] Because the second air guide tube 12 is long, the negative pressure difference between the two ends of the second air guide tube 12 may be too large during use, affecting the air circulation effect. On each set of manifolds 13, the air inlets 14 are distributed more sparsely at locations closer to the second air guide tube 12 and more densely at locations farther away from the second air guide tube 12, thereby minimizing the negative pressure difference between the two ends of the second air guide tube 12.
[0034] The processing workshop 1 is equipped with multiple production lines and workshops. Each production line and workshop is equipped with a corresponding shunt pipe 6 and manifold 13. When a production line or workshop needs to be shut down, the corresponding shunt pipe 6 and manifold 13 also need to be closed simultaneously. Each group of shunt pipes 6 is connected to a first solenoid valve 9, and each group of second flow guide pipes 12 is equipped with a second solenoid valve 15. When it is necessary to close a group of shunt pipes 6 and manifold 13, the corresponding first solenoid valve 9 and second solenoid valve 15 can be adjusted to a closed state to adjust the flow state of the group of shunt pipes 6 and manifold 13.
[0035] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
