Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of air compressor technology, and more specifically, to an air compressor heat recovery mechanism. Background Technology

[0002] Air compressors are widely used as a common piece of equipment in industrial production and many other fields. During operation, air compressors generate a large amount of heat energy. However, under the traditional operating mode, most of this heat energy is directly discharged into the environment without being effectively utilized. This not only causes a huge waste of energy but also increases production costs. According to relevant statistics, if the heat energy generated by air compressors can be effectively recovered, it can meet 30%-50% of the heat energy needs of other processes in the factory. Therefore, the development of efficient air compressor heat recovery technology is urgent.

[0003] Meanwhile, some production environments or specific spaces have strict requirements for air humidity. For example, in the textile industry, excessively low air humidity can lead to yarn breakage and severe static electricity in fabrics, affecting product quality. In electronic chip manufacturing workshops, suitable humidity can prevent static electricity from damaging chips. Common humidification methods, such as ultrasonic humidification and electric heating humidification, are not only energy-intensive, but their humidification effect is also greatly affected by factors such as ambient temperature. If the waste heat generated by the operation of air compressors can be used for air humidification, it can achieve heat energy recovery and utilization, and meet humidification needs at a lower cost, which will have significant economic and environmental benefits. However, there is currently a lack of an integrated mechanism on the market that can closely combine air compressor heat energy recovery with efficient humidification. The air compressor heat energy recovery mechanism designed is developed to solve these problems. Utility Model Content

During the operation of air compressors, a large amount of heat energy is generated. However, in the traditional operating mode, most of this heat energy is directly discharged into the environment and is not effectively utilized. This not only causes a great waste of energy, but also increases production costs.

[0005] According to one aspect, at least one embodiment of this disclosure provides an air compressor heat recovery mechanism, comprising:

[0006] A hot press air outlet mounting sleeve, wherein an air outlet pipe is provided at the upper end of the hot press air outlet mounting sleeve;

[0008] A plug-in mounting assembly is disposed on the hot press air outlet mounting sleeve;

[0009] The humidifying spray assembly includes a mounting frame, which is disposed on the upper end face of the air outlet pipe. A mounting sleeve is provided on the mounting frame, and an atomizing pump is inserted into the mounting sleeve. The liquid outlet end of the atomizing pump is inserted into the interior of the air outlet pipe. The liquid outlet end of the atomizing pump is connected to a mounting block, and a guide plate is provided on the lower end face of the mounting block.

[0010] As a further technical solution, the side wall of the air outlet pipe is provided with an elbow pipe, the elbow pipe is fixedly connected to the air outlet mounting sleeve of the hot press, and the end of the air outlet pipe is provided with an exhaust port.

[0011] As a further technical solution, the plug-in installation assembly includes a plug-in sleeve, which is disposed on the inner side wall of the hot press air outlet mounting sleeve. A screw is provided on the side wall of the hot press air outlet mounting sleeve. One end of the screw is inserted into the interior of the hot press air outlet mounting sleeve. A clamping plate is provided at the end of the screw, and a rotating nut is provided on the screw.

[0012] As a further technical solution, the side wall of the clamping plate is provided with a clamping anti-slip pad, the plug sleeve is an inverted trapezoidal structure, and the outer side wall of the plug sleeve is provided with a plug sealing gasket.

[0013] As a further technical solution, the lower end face of the hot press air outlet mounting sleeve is any one of a rectangle, a circle, or a polygon, and the shape of the hot press air outlet mounting sleeve matches the shape of the air compressor air outlet.

[0014] As a further technical solution, both the air outlet pipe and the elbow pipe are rectangular structures, the exhaust port is a circular structure, and the exhaust port and the air outlet pipe are sealed and plugged together.

[0015] As a further technical solution, the mounting frame and the air outlet pipe are fixed and screwed together by bolts, and the included angle between the atomizing pump and the air outlet pipe is 45°.

[0016] As a further technical solution, the flow guide plate has an air vent and a drip outlet vertically formed on it.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this disclosure, the mechanism collects the waste heat generated by the air compressor through the air outlet sleeve of the hot compressor, and delivers hot air through the air outlet pipe. The humidifying spray component cleverly utilizes this hot air to heat and diffuse the liquid sprayed by the atomizing pump, so that the originally wasted heat energy can be reused, realizing the cascade utilization of energy. According to actual tests, under the same working conditions, after adopting this heat energy recovery mechanism, the overall energy consumption of the factory can be reduced by 15%-20% compared with the case of no heat energy recovery, effectively reducing energy costs and conforming to the current green development concept of energy conservation and emission reduction.

[0019] 2. In this disclosure, the coordinated design of the mounting frame, atomizing pump, mounting block, and guide plate in the humidifying spray assembly enables the liquid to be uniformly atomized and fully mixed with hot air. The atomizing pump is installed in the air outlet duct at a 45° angle, and together with the air inlet and drip outlet on the guide plate, the humidification amount can be precisely adjusted according to the hot air flow rate and humidity requirements. When used in places with high humidity requirements, such as textile workshops, the air humidity can be stably controlled within the set range, and the humidity fluctuation range can be controlled within ±2%, which greatly improves the production environment, improves product quality, and reduces the defect rate by 10%-15%.

[0032] like Figures 1-4As shown, it illustrates a heat recovery mechanism for an air compressor according to this disclosure, comprising:

[0033] Hot press air outlet mounting sleeve 1, with an air outlet pipe 2 installed at the upper end of hot press air outlet mounting sleeve 1;

[0034] Humidifying spray component 3 is installed inside the air outlet duct 2;

[0035] The plug-in mounting component 4 is installed on the hot press air outlet mounting sleeve 1;

[0036] The humidifying spray assembly 3 includes a mounting frame 3-1, which is located on the upper end face of the air outlet duct 2. A mounting sleeve 3-2 is provided on the mounting frame 3-1, and an atomizing pump 3-3 is inserted into the mounting sleeve 3-2. The liquid outlet end of the atomizing pump 3-3 is inserted into the interior of the air outlet duct 2. The liquid outlet end of the atomizing pump 3-3 is connected to a mounting block 3-4, and a guide plate 3-5 is provided on the lower end face of the mounting block 3-4.

[0037] The plug-in mounting assembly 4 includes a plug-in sleeve 4-1, which is located on the inner side wall of the hot press air outlet mounting sleeve 1. A screw-on bolt 4-2 is provided on the side wall of the hot press air outlet mounting sleeve 1. One end of the screw-on bolt 4-2 is inserted into the interior of the hot press air outlet mounting sleeve 1. A clamping plate 4-3 is provided at the end of the screw-on bolt 4-2. A rotating nut 4-4 is provided on the screw-on bolt 4-2.

[0038] In some examples, during installation, the hot press air outlet mounting sleeve 1 is aligned with the air compressor air outlet, ensuring a tight fit. If there is a gap between the mounting sleeve and the air outlet, high-temperature resistant sealant can be used to fill and seal it to prevent hot air leakage. The inner wall of the hot press air outlet mounting sleeve 3-2 is provided with a plug-in sleeve 4-1, which is inserted into the corresponding position of the air compressor air outlet. Then, it is tightened by the screw 4-2 on the side wall of the hot press air outlet mounting sleeve 1, with one end of the screw 4-2 inserted into the hot press air outlet mounting sleeve 1. Internally, the end is connected to the clamping plate 4-3. Rotate the rotating nut 4-4 on the screw 4-2 to gradually bring the clamping plate 4-3 closer to the air compressor outlet, clamping and securing it. The exhaust port 3-7 has a circular structure and is connected to the outlet pipe 2 via a sealed plug-in connection. Before plugging, apply sealant to the interface between the exhaust port 3-7 and the outlet pipe 2 to enhance sealing performance. After insertion, use clamps or clips to tighten, ensuring a tight connection between the exhaust port 3-7 and the outlet pipe 2, preventing it from falling off or leaking during operation. The mounting bracket 3-1 is fixedly screwed to the upper end face of the air outlet pipe 2 with bolts. Before installation, holes need to be pre-drilled in the air outlet pipe 2. The position and size of the holes should precisely match the bolt holes on the mounting bracket 3-1. During installation, place the mounting bracket 3-1 on the air outlet pipe 2, align the bolt holes, and tighten the bolts to ensure that the mounting bracket 3-1 is securely installed on the air outlet pipe 2. Insert the atomizing pump 3-3 into the mounting sleeve, which is set on the mounting bracket 3-1. During installation, pay attention to ensuring that the liquid outlet end of the atomizing pump 3-3 is accurately inserted. Inside the air inlet / outlet duct 2, the angle between the atomizing pump 3-3 and the air outlet duct 2 is adjusted to 45°. This angle setting allows the atomized liquid to mix better with the hot air in the air outlet duct 2, improving the humidification effect. After inserting the atomizing pump 3-3, it can be fixed with nuts or clamps to prevent the atomizing pump 3-3 from shifting during operation. Installation of mounting block 3-4 and guide plate 3-5: The liquid outlet end of the atomizing pump 3-3 is connected to the mounting block 3-4, and the guide plate 3-5 is installed on the lower end face of the mounting block 3-4.

[0039] like Figures 1-4 As shown in the figure, this embodiment proposes that the side wall of the air outlet pipe 2 is provided with an elbow pipe 3-6, the elbow pipe 3-6 is fixedly connected to the air outlet mounting sleeve 1 of the hot press, and the end of the air outlet pipe 2 is provided with an exhaust port 3-7.

[0040] In some examples, the elbow pipe 3-6 on the side wall of the air outlet duct 2 is fixedly connected to the air outlet mounting sleeve 1 of the hot press by welding or high-strength bolts to ensure a firm connection and good sealing to prevent hot air leakage.

[0041] For example, such as Figure 3 As shown, the side wall of the clamping plate 4-3 is provided with a clamping anti-slip pad 4-5, the plug sleeve 4-1 is an inverted trapezoidal structure, and the outer side wall of the plug sleeve 4-1 is provided with a plug sealing gasket 4-6.

[0042] In some examples, the clamping anti-slip pads 4-5 on the sidewalls of the clamping plate 4-3 increase friction and prevent the mounting sleeve from loosening during operation. The insertion sleeve 4-1 has an inverted trapezoidal structure, which helps to form a tight fit when inserted. Meanwhile, the insertion sealing gaskets 4-6 on the outer sidewalls further enhance the sealing effect.

[0043] For example, such as Figure 2 As shown, the lower end face of the hot press air outlet mounting sleeve 1 is any one of rectangle, circle or polygon, and the shape of the hot press air outlet mounting sleeve 1 matches the shape of the air compressor air outlet.

[0044] In some examples, the shape of the lower end face of the hot press air outlet mounting sleeve 1 needs to be precisely matched with the shape of the air compressor air outlet, which can be rectangular, circular or polygonal, etc., depending on the actual situation.

[0045] For example, such as Figure 1 As shown, both the air outlet duct 2 and the elbow duct 3-6 are rectangular structures, while the exhaust port 3-7 is circular. The exhaust port 3-7 and the air outlet duct 2 are sealed and connected together.

[0046] In some examples, when both the air outlet duct 2 and the elbow ducts 3-6 are rectangular structures, the joints need to be ground before welding to remove rust, oil, and other impurities from the surface in order to ensure welding quality.

[0047] For example, such as Figure 1 As shown, the mounting frame 3-1 and the air outlet pipe 2 are fixed and screwed together by bolts. The angle between the atomizing pump 3-3 and the air outlet pipe 2 is 45°. The guide plate 3-5 has an air outlet 5 and a drip outlet 6 is vertically opened on the guide plate 3-5.

[0048] In some examples, the baffle plate 3-5 has an air outlet 5 and a vertical drip nozzle 6. During installation, ensure that the baffle plate 3-5 is installed firmly and that the air outlet 5 and the drip nozzle 6 are in the correct direction. The air outlet 5 allows hot air to pass through smoothly to heat and diffuse the atomized liquid, while the drip nozzle 6 is used to drip off the liquid that is not completely atomized, preventing the liquid from accumulating in the air outlet duct 2.

[0049] During operation, the compressed air generates a large amount of heat, which is discharged from the outlet as hot air. The hot air outlet mounting sleeve 1 serves as the starting point of the entire mechanism. With its shape matching the air outlet of the air compressor, it is tightly connected to the outlet and efficiently collects the discharged hot air. The hot air flows along the outlet pipe 2, which acts as a "high-speed channel" for transporting heat energy, stably delivering the hot air to the area where the humidifying spray component 3 is located.

[0050] The humidifying spray assembly 3 begins to play a crucial role. The mounting bracket 3-1 is securely installed on the upper end of the air outlet duct 2, providing support for the atomizing pump 3-3. After the atomizing pump 3-3 is powered on and started, it draws and pressurizes the liquid from the storage container and sprays it out in a mist form through the liquid outlet. Since the atomizing pump 3-3 is installed at a 45° angle inside the air outlet duct 2, the sprayed mist liquid can meet the hot air at the optimal angle. The guide plate 3-5 is located below the liquid outlet of the atomizing pump 3-3, and the air passage 5 on its surface allows the hot air to pass through smoothly. When the hot air passes through, it will drive the mist droplets to further diffuse and heat the mist droplets, accelerating the evaporation of water and allowing water vapor to be integrated into the hot air more quickly, thus humidifying the hot air. The vertically opened drip port 6 on the guide plate 3-5 is used to collect the liquid that is not completely atomized, allowing it to drip down in an orderly manner and avoiding accumulation in the air outlet duct 2 that could cause blockage.

[0051] Throughout the process, the plug-in installation component 4 ensures a tight connection between the hot press air outlet mounting sleeve 1 and the air compressor air outlet to prevent hot air leakage; the reasonable design of the air outlet pipe 2 and the elbow pipe 3-6 ensures the smooth delivery of hot air; the exhaust port 3-7 discharges the humidified hot air to the target area to meet the humidity and temperature requirements of the production environment. In this way, the waste heat generated by the air compressor can be effectively recovered and utilized, while accurately realizing the humidification operation of the air.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
