Description

Technical Field

[0001] This utility model relates to the field of pallet manufacturing technology, and in particular to a waste heat utilization system for air compressors. Background Technology

[0002] In the pallet manufacturing process, raw materials (pallet masterbatch) must undergo multiple processes, including conveying, drying, melting, molding, material handling, and waste cutting. The drying and melting processes both require significant thermal energy input: the masterbatch must be dried to remove moisture before melting, and melting requires heating to ensure complete melting; both are energy-intensive processes. Simultaneously, the entire production system generates various forms of waste heat, especially a large amount of unused industrial waste heat from the operation of air compressors.

[0003] In summary, in order to improve overall energy utilization efficiency and realize the recycling of energy in the production process, this utility model designs an air compressor waste heat utilization system, which aims to effectively recover the waste heat emitted by the air compressor and apply it to heat-requiring processes such as masterbatch drying and smelting, thereby reducing the original energy consumption and improving the system energy efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste heat utilization system for air compressors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air compressor waste heat recovery system, comprising

[0007] An air compressor room, which contains several air compressors;

[0008] The material supply room contains several dryers.

[0009] The air compressor is equipped with a branch pipe, which is connected to the main pipe. The main pipe extends from the air compressor room to the material supply room.

[0010] The dryer is equipped with a second branch pipe, which is connected to the main pipe;

[0011] The free end of branch pipe one is equipped with a suction hood, and a sealing device is provided below the suction hood. The sealing device is detachably fixed to the end of the suction hood, and the free end of the sealing device is in contact with the upper surface of the air compressor.

[0012] As a further preferred embodiment, the sealing device includes a sealing frame and a support rod. The bottom of the sealing frame extends toward the center of the sealing frame, and the support rod is located at the intersection of the sides of the sealing frame and extends away from the bottom of the sealing frame with a sealing portion.

[0013] As a further preferred option, the support rod is L-shaped.

[0014] As a further preferred embodiment, the support rod includes a support arm one and a support arm two, with the width of support arm one being a and the width of support arm two being b, satisfying the quantitative relationship: a=b.

[0015] As a further preferred embodiment, the sealing frame extends upward to provide a second sealing portion.

[0016] As a further preferred option, a baffle is also included, which is detachably fixed to the support rod.

[0017] This utility model is reasonably designed, easy to operate, has high feeding and dissolving efficiency, and is highly practical, with the following beneficial effects:

[0018] 1) By connecting the air compressor 20 and the dryer 40 through pipelines, the waste heat discharged from the air compressor can be effectively recovered and applied to the heat-requiring process of masterbatch drying, thereby reducing the original energy consumption and improving the system energy efficiency of the workshop.

[0019] 2) Through the synergistic action of the extension of the sealing frame, the L-shaped support rod, and the baffle with sealing gasket, multiple sealing effects are achieved: Firstly, the extension at the bottom of the sealing frame achieves preliminary planar sealing; secondly, the adjustable and compressed baffle, through its flexible sealing gasket at its end, adapts to the unevenness of the air compressor housing surface and provides a reliable main sealing surface, effectively preventing leakage of high-temperature airflow. The above-mentioned device has a stable structure, is not only easy to install and disassemble, but also significantly improves the efficiency of waste heat collection, avoiding energy loss and temperature rise in the air compressor room caused by intermittent heat dissipation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Referring to the figure, this utility model provides an air compressor waste heat utilization system.

[0026] Example 1

[0027] An air compressor waste heat recovery system, comprising

[0028] Air compressor room 10, which is equipped with several air compressors 20;

[0029] The material supply room 30 contains several dryers 40;

[0030] The air compressor 20 is provided with a branch pipe 21, which is connected to the main pipe 50. The main pipe 50 extends from the air compressor room 10 to the material supply room 30.

[0031] The dryer 40 is equipped with a second branch pipe 41, which is connected to the main pipe 50;

[0032] The free end of the branch pipe 21 is provided with a suction hood 22, and a sealing device 60 is provided below the suction hood 22. The sealing device 60 is detachably fixed to the end of the suction hood 22, and the free end of the sealing device is in contact with the upper surface of the air compressor 20.

[0033] In this embodiment, by connecting the air compressor 20 and the dryer 40 through pipelines, the waste heat emitted by the air compressor can be effectively recovered and applied to the heat-requiring stage of masterbatch drying, thereby reducing the original energy consumption and improving the system energy efficiency of the workshop.

[0034] Furthermore, in the existing technology, there is a gap between the suction hood 22 and the air compressor 20, which causes some heat to dissipate. This not only makes the temperature of the air compressor room too high, but also reduces the energy utilization rate. Heat will flow into the air through the gap between the suction hood 22 and the air compressor 20. In this embodiment, a sealing device 60 is provided below the suction hood 22. The sealing device 60 is detachably fixed to the end of the suction hood 22, and the free end of the sealing device is in contact with the upper surface of the air compressor 20.

[0035] In this embodiment, by transporting the high-temperature exhaust gas generated during the operation of the air compressor 20 to the dryer 40 via the main pipeline 50 for heating needs during the masterbatch drying process, the efficient recovery and utilization of waste heat is achieved, significantly reducing the original energy consumption in the production process and improving the overall energy utilization efficiency of the workshop.

[0036] Furthermore, in response to the problem in the prior art that there is an installation gap between the suction hood 22 and the upper surface of the air compressor 20, resulting in heat loss, excessively high local temperature in the air compressor room, and reduced waste heat recovery efficiency, this embodiment provides a sealing device 60 at the bottom of the suction hood 22, which fits tightly against the upper surface of the air compressor 20, effectively preventing the leakage of high-temperature gas and ensuring that most of the waste heat is recovered and transported to the drying system, thereby improving the system's thermal insulation performance and heat utilization efficiency.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 is as follows:

[0039] The sealing device 60 includes a sealing frame 61 and a support rod 62. The bottom of the sealing frame 61 extends toward the center of the sealing frame. The support rod 61 is located at the intersection of the sides of the sealing frame 61 and extends away from the bottom of the sealing frame 61 with a sealing part 613.

[0040] Support rod 61 is L-shaped;

[0041] The support rod 61 includes a first support arm 611 and a second support arm 612. The width of the first support arm 611 is a, and the width of the second support arm 612 is b, satisfying the quantitative relationship: a=b.

[0042] The sealing frame 61 extends upward to provide a sealing part 614.

[0043] It also includes a baffle 63, which is detachably fixed to the support rod 62.

[0044] A sealing gasket is provided at the end of the baffle 63. The sealing gasket (not shown in the figure) is made of high-temperature resistant rubber or silicone material. The baffle 63 is fixed to the support rod 62 and the port of the suction hood 22 by bolts. By providing a sealing gasket at the end of the baffle 63, the bottom is made to fit against the upper surface of the air compressor 20, which not only adapts to its unevenness but also achieves a seal.

[0045] In this embodiment, the sealing device further includes a baffle 63, which is detachably fixed to the support rod 62 by bolts. A sealing gasket (not shown in the figure) made of high-temperature resistant rubber or silicone material is embedded at the end of the baffle 63. During assembly, tightening the bolts tightly presses the sealing gasket at the end of the baffle 63 against the upper surface of the air compressor 20, while simultaneously securing the support rod 62 and the entire sealing device to the port of the suction hood 22.

[0046] Through the synergistic action of the extension of the sealing frame 61, the L-shaped support rod 62, and the baffle 63 with a sealing gasket, multiple sealing effects are achieved: First, the extension at the bottom of the sealing frame achieves a preliminary planar seal; second, the adjustable and compressed baffle 63, through its flexible sealing gasket at its end, adapts to the unevenness of the air compressor housing surface and provides a reliable main sealing surface, effectively preventing the leakage of high-temperature airflow. The above-mentioned device has a robust structure, is not only easy to install and disassemble, but also significantly improves the efficiency of waste heat collection, avoiding energy loss due to intermittent heat dissipation and the problem of increased ambient temperature in the air compressor room.

[0047] In practice:

[0048] The sealing frame 61 can be a rectangular or square metal frame (the frame structure matches the structure of the suction hood 22), and its bottom extension is a heat-resistant metal plate with a width of 20-50mm. Four L-shaped support rods 62 are fixed to the four corners of the sealing frame 61 by welding or bolts. There are four baffles 63, whose shape matches the four sides of the sealing frame 61. Each baffle 63 is connected to the support arms 612 of two adjacent support rods 62 by two bolts. When the bolts are tightened, the baffles 63 are pressed downwards, causing the strip-shaped sealing gasket at its end to elastically deform and tightly adhere to and seal the upper surface of the air compressor 20. When maintenance of the air compressor is required, simply loosening the bolts allows the entire suction hood 22 and sealing device 60 to be removed together, making operation extremely convenient.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
