Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, and more specifically, it relates to a waste heat recovery type air compressor energy-saving unit. Background Technology

[0002] An air compressor, also known as an air compressor, is a device that compresses atmospheric air into high-pressure gas, and then delivers the compressed high-pressure gas to an air storage tank or directly for various industrial applications.

[0003] Because air compressors inevitably generate a lot of heat during the air compression process, this heat is generated due to the friction between air molecules and the conversion of compression work during the compression process. Therefore, the high-pressure gas discharged from the air compressor's exhaust pipe will naturally have a higher temperature. If the heat contained in these high-temperature and high-pressure gases is not converted into usable thermal energy through effective technical means, but is directly discharged into the environment, it will cause a waste of valuable energy. This will not only be detrimental to the efficient use of energy, but will also increase the operating costs of enterprises and even cause certain thermal pollution to the environment.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a waste heat recovery type air compressor energy-saving unit in order to achieve a more practical value. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model improves waste heat recovery efficiency: By using the spiral blade design inside the gas output cylinder, the residence time of high-temperature waste gas in the flow channel is extended.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a waste heat recovery type air compressor energy-saving unit, including an air compressor 1. The exhaust gas output end of the air compressor 1 is connected to an exhaust pipe 2. The output end of the exhaust pipe 2 is connected to a waste heat recovery component 3. The waste heat recovery component 3 includes a mounting base 301, a cold water storage tank 302, and a gas output tank 304. The cold water storage tank 302 is rotatably mounted on the mounting base 301. The gas output tank 304 is disposed in the cold water storage chamber 3021 of the cold water storage tank 302, with one end connected to the exhaust pipe 2 and the other end serving as an exhaust gas outlet. The gas output cylinder 304 has a double-layer structure. The inner layer is a gas flow channel 3042, and a spiral blade 3043 is rotatably installed on its inner wall. The spiral blade 3043 extends spirally along the gas flow direction. The outer layer forms an interlayer 3041, which stores water. The top of the cold water storage cylinder 302 is provided with an opening 303 for cold water injection and hot water discharge. The cold water storage chamber 3021 is provided with a temperature monitoring component and a drive component for driving the cold water storage cylinder 302 to rotate. The drive component and the temperature monitoring component are electrically connected.

[0019] The spiral blade 3043 has a rotating shaft 3044 installed in the middle. The rotating shaft 3044 and the gas output cylinder 304 are concentric, and a retainer is rotatably installed at one end. The retainer is installed on the outer wall of the cold water storage cylinder 302. The rotating shaft 3044 and the gas output cylinder 304 are concentrically arranged. The retainer on the outer wall is installed on the cold water storage cylinder 302 to ensure that the spiral blade 3043 rotates stably and avoids structural wear caused by eccentric vibration. At the same time, the concentric design makes the spiral blade 3043 evenly disturb the airflow and improve the heat exchange efficiency with the water source in the interlayer 3041.

[0020] The rotating connection between the cold water storage tank 302 and the mounting base 301 is equipped with a sealed bearing. The inner ring of the sealed bearing is interference-fitted with the outer wall of the cold water storage tank 302, and the outer ring is clearance-fitted with the mounting groove of the mounting base 301. The interference fit between the inner ring and the cold water storage tank 302 enhances the connection stability, while the clearance fit between the outer ring and the mounting base 301 reduces rotational friction resistance. The dual-fit design balances sealing performance to prevent water leakage and rotational flexibility, extending the service life of the equipment.

[0021] The drive assembly includes a drain gear ring 305 mounted on the side wall of the cold water storage tank 302. A drain gear 306 is meshed on the side wall of the drain gear ring 305. The drain gear 306 is connected to a motor. The motor is mounted on the side wall of the mounting base 301. The gear meshing transmission structure between the drain gear ring 305 and the drain gear 306 provides precise power transmission. The motor is fixed to the side wall of the mounting base 301 for easy maintenance. The overall design ensures that the cold water storage tank 302 rotates smoothly and adjusts efficiently when responding to the temperature monitoring component signal.

[0022] The mounting base 301 has an annular guide groove on its upper surface, and the bottom of the cold water storage tank 302 has a ball set that cooperates with the guide groove. The ball set has multiple balls evenly distributed around the guide groove. The annular guide groove restricts the rotation trajectory. In conjunction with the evenly distributed ball set, sliding friction is converted into rolling friction, reducing energy consumption. At the same time, it improves the stability of the cold water storage tank 302 when it rotates, and avoids tilting or jamming.

[0023] The temperature monitoring component includes a float 4 disposed in the cold water storage chamber 3021. A vacuum layer 5 is provided on the outer wall of the float 4, and alcohol is filled in the vacuum layer 5. A guide rod 6 is installed on the top of the float 4. A first sliding frame 7 and a second sliding frame 8 are slidably mounted on the outer wall of the guide rod 6. The second sliding frame 8 is located on the inner wall of the cold water storage chamber 3021 and is located above the first sliding frame 7. A contact sensor 9 for cooperating with the outer wall of the float 4 is provided on the bottom side of the first sliding frame 7.

[0024] Working principle of this embodiment: exhaust gas introduction and heat exchange: the high-temperature exhaust gas generated by the air compressor 1 enters the gas output cylinder 304 inner gas flow channel 3042 of the waste heat recovery component 3 through the exhaust pipe 2. The spiral blades 3043 on the inner wall of the channel rotate with the air flow, prolonging the residence time of the exhaust gas and enhancing the disturbance. The water source in the outer interlayer 3041 absorbs the heat of the exhaust gas through heat conduction, realizing waste heat recovery. Temperature monitoring and signal transmission: The float 4 in the cold water storage chamber 3021 adjusts its position by the thermal expansion and contraction of the alcohol in the vacuum layer 5, which drives the guide rod 6 and the first sliding frame 7 and the second sliding frame 8 on the outer wall to move. When the float 4 contacts the contact sensor 9 at the bottom of the first sliding frame 7, it triggers a temperature signal and transmits it to the drive assembly. Drive adjustment and rotation control: When the water temperature reaches the standard, the motor of the drive component is installed on the side wall of the mounting base 301 and drives the drain gear 306 to rotate, which meshes with the drain gear ring 305 on the side wall of the cold water storage tank 302, driving the cold water storage tank 302 to rotate along the annular guide groove of the mounting base 301 with the bottom ball set assisting in sliding. The opening 303 at the top of the cold water storage tank 302 discharges hot water to achieve continuous waste heat recovery and energy-saving operation.

Many modifications and variations will be apparent to those skilled in the art.
