Technical Field
[0001] This utility model belongs to the field of air compressor technology, specifically an air compressor waste heat utilization device. Background Technology
[0002] An air compressor is a device that provides power by compressing air. During the compression process, mechanical energy is converted into heat energy, causing the internal temperature of the air compressor to rise. Typically, air compressors release a large amount of heat energy during operation. If this heat energy is not utilized, it will be wasted. Air compressors are widely used in industrial production, but the heat generated during their operation is often overlooked. With rising energy prices and stricter environmental protection requirements, how to effectively utilize this waste heat has become a key focus for enterprises. Waste heat utilization can not only reduce the operating costs of enterprises, but also reduce energy consumption and environmental pollution.
[0003] Existing waste heat recovery devices for air compressors have the following main shortcomings:
[0004] Existing waste heat recovery devices for air compressors mostly rely on manual handling of materials in and out of the drying chamber. This is not only labor-intensive but also has a limited capacity for handling materials at one time. It is especially inefficient for heavy or bulk materials. Oil stains, odors, and other pollutants in the waste heat of the air compressor cause oil stains or impurities to adhere to the surface of the dried materials, resulting in a pass rate of less than 70%. This is completely unsuitable for materials with high cleanliness requirements, such as food and electronic components. Utility Model Content

[0011] As a further embodiment of this utility model: the lifting structure includes a mounting frame, which is located at the rear center of the upper surface of the connecting plate. An electric telescopic rod is provided at the center of the inner wall of the mounting frame. A connecting block is provided at the center of the lower end face of the electric telescopic rod. A telescopic plate is fixedly connected to the center of the rear end face of the connecting block. A feeding trough is provided at the upper center of the front face of the drying box. The feeding trough and the telescopic plate are mutually compatible.
[0012] As a further embodiment of this utility model: the preheating utilization structure includes an air inlet fan, which is located at the center of the upper end face of the drying box on one side.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] like Figures 1-4 As shown, this utility model provides a technical solution:
[0024] An air compressor waste heat recovery device, comprising:
[0025] The drying oven 1 has a control panel 2 located at the center of one side wall, a connecting plate 3 located at the lower center of the front face of the drying oven 1, a movable structure 4 located at both sides of the center of the upper face of the connecting plate 3, a lifting structure 5 located at the rear center of the upper face of the connecting plate 3, and a preheating utilization structure 6 located at the upper center of the interior of the drying oven 1.
[0026] The two movable structures 4 include two frames 401, which are respectively located on the upper surface of the connecting plate 3 near the center on both sides. One end of each frame 401 penetrates the front end of the drying chamber 1 and extends into the interior of the drying chamber 1. Each frame 401 has a sliding groove 402 at the center of its upper surface, and a lead screw 403 is located at the center of each sliding groove 402. One end of each lead screw 403 penetrates the inner front wall of the two sliding grooves 402 and the inner front wall of the two frames 401, extending to the front end of the two frames 401. Each end is fixedly connected to a pulley 404, and a belt is fitted onto the outer wall of each pulley 404. A fixing frame 405 is located at the center of the front end of one side of the frame 401, and a servo motor 406 is located at the center of the front end of the fixing frame 405. The output end of the servo motor 406 is fixedly connected to one end of the pulley 404 on one side. The outer wall of the lead screw 403 is threaded with sliders 407. A placement box 408 is provided at the center of the upper end face of the two sliders 407. A waste box 409 is slidably connected to the lower center of the placement box 408. One end of the waste box 409 passes through the front inner wall of the placement box 408 and extends to the front end face of the placement box 408. Guide grooves 410 are provided on the upper sides of the front inner wall and the upper sides of the rear inner wall of the placement box 408. Guide blocks 411 are slidably connected to the center of the four guide grooves 410. A placement platform 412 is provided between the four guide blocks 411. The front end face of the placement platform 412 is fixedly connected to the lower center of the rear end face of the two front guide blocks 411. The rear end face of the placement platform 412 is fixedly connected to the lower center of the front end face of the two rear guide blocks 411. The four guide blocks 411 are slidably connected to the center of the four guide grooves 410 respectively.
[0027] By placing the material to be dried on the placement platform 412, the placement platform 412 slides in the guide groove 410 of the placement box 408 via the guide block 411. The waste box 409 at the bottom of the placement box 408 is used to collect the debris or waste that falls during the material drying process. By starting the servo motor 406 on the fixed frame 405, the pulley 404 on one side is driven to rotate. The pulley 404 on the other side is driven to rotate synchronously through the belt drive, which in turn drives the lead screw 403 in the two frames 401 to rotate in the same direction in the slide groove 402. Since the slider 407 is threadedly connected to the lead screw 403, when the lead screw 403 rotates, the slider 407 slides backward along the slide groove 402, which drives the entire placement box 408 to move backward, which facilitates the drying of the material.
[0028] The lifting structure 5 includes a mounting frame 501, which is located at the rear center of the upper end face of the connecting plate 3. An electric telescopic rod 502 is located at the center of the inner wall of the mounting frame 501. A connecting block 503 is located at the center of the lower end face of the electric telescopic rod 502. A telescopic plate 504 is fixedly connected to the center of the rear end face of the connecting block 503. A feeding trough 505 is located at the upper center of the front end face of the drying chamber 1. The feeding trough 505 and the telescopic plate 504 are mutually compatible. When it is necessary to dry the material, the electric telescopic rod 502 on the mounting frame 501 is extended, which pushes the connecting block 503 and the rear telescopic plate 504 to move upward, so that the feeding trough 505 at the front end of the drying chamber 1 opens, providing a channel for the material to enter the interior of the drying chamber 1.
[0029] The preheating structure 6 includes an air inlet fan 601, which is located at the center of the upper end face of the drying chamber 1. An air inlet connecting pipe 602 is located at the center of the rear end face of the air inlet fan 601, and an exhaust connecting pipe 603 is located at the lower center of the front end face of the air inlet fan 601. The exhaust connecting pipe 603 passes through the upper end face of the drying chamber 1 and leads to the interior of the drying chamber 1. Three sliding frames 604 are arranged vertically at the upper center of the interior of the drying chamber 1. Each of the three sliding frames 604 has a slidingly connected lifting box 605 at its center. One end of each of the three lifting boxes 605 passes through an inner wall of one of the three sliding frames 604 and an inner wall of the drying chamber 1, leading to a side wall of the drying chamber 1. A filter screen 606 is located at the center of the upper sliding frame 604. The lower end of the sliding frame 604... Activated carbon 607 is located at the center of the sliding frame 604, and adsorption cotton 608 is located at the lower end of the activated carbon 607 and at the center of the sliding frame 604. The air inlet fan 601 is connected to the high-temperature waste heat air generated by the air compressor through the air inlet connection pipe 602. The high-temperature waste heat air is sent into the drying box 1 through the exhaust connection pipe 603. The hot air enters the upper lifting box 605 and passes through the filter screen 606 to filter dust and particulate matter in the air, the activated carbon 607 to adsorb oil stains, odors and other harmful substances, and the adsorption cotton 608 to purify fine impurities, thus completing the purification treatment of the waste heat air and preventing pollutants from adhering to the materials. The purified air is in full contact with the materials on the placement platform 412, and the waste heat is used to heat and dry the materials.
[0030] The working principle of this utility model is as follows: When material drying is required, the electric telescopic rod 502 on the mounting frame 501 is extended, pushing the connecting block 503 and the telescopic plate 504 at the rear end to move upward, so that the feeding chute 505 at the front end of the drying chamber 1 opens, providing a channel for the material to enter the drying chamber 1. The material to be dried is placed on the placement platform 412. The placement platform 412 slides in the guide groove 410 of the placement box 408 through the guide block 411, which facilitates the installation of the placement platform 412. The waste box 409 at the bottom of the placement box 408 is used to collect the debris or waste that falls during the material drying process. After the material is placed on the placement platform 412, the servo motor on the fixing frame 405 is activated. 406 drives the pulley 404 on one side to rotate, and through belt transmission, the pulley 404 on the other side rotates synchronously, thereby driving the lead screws 403 in the two frames 401 to rotate in the same direction in the slide groove 402. Since the slider 407 is threadedly connected to the lead screw 403, when the lead screw 403 rotates, the slider 407 slides backward along the slide groove 402, driving the placement box 408 to move backward as a whole, and enter the drying chamber 1 through the open feed chute 505. When the placement box 408 is completely inside the drying chamber 1, the electric telescopic rod 502 of the lifting structure 5 retracts, driving the telescopic plate 504 to descend, closing the feed chute 505, ensuring that a relatively sealed space is formed inside the drying chamber 1, reducing residual heat loss and improving drying efficiency.
[0031] The air intake fan 601 connects to the high-temperature waste heat air generated by the air compressor via the air intake connection pipe 602. The waste heat air generated during the operation of the air compressor is then sent into the drying chamber 1 via the exhaust connection pipe 603. The hot air enters the upper lifting box 605 and sequentially passes through the filter screen 606 to filter dust, particulate matter, activated carbon 607 to adsorb oil stains, odors, and other harmful substances, and adsorption cotton 608 to purify fine impurities. This completes the purification of the waste heat air, preventing pollutants from adhering to the materials. The purified high-temperature waste heat air then comes into full contact with the materials on the placement platform 412, using the waste heat to heat and dry the materials. After drying is complete, the lifting mechanism is activated... The electric telescopic rod 502 of the lowering structure 5 extends again, opening the feeding chute 505. The servo motor 406 of the moving structure 4 rotates in the opposite direction. Through the reverse transmission of the pulley 404, belt and lead screw 403, the slider 407 drives the placement box 408 to slide forward along the slide chute 402 and exit from the feeding chute 505 to the outside of the drying box 1. The operator can take out the dried material, pull out the waste box 409 at the bottom of the placement box 408, and clean the debris collected inside. The filter screen 606, activated carbon 607 and adsorption cotton 608 are vulnerable parts and can be replaced regularly by pulling out the lifting box 605 in the sliding frame 604 to ensure the purification effect of the waste heat air.
[0032] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
