Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and in particular to a waste heat recovery type air compressor and a waste heat recovery method. Background Art

[0002] In many industrial enterprises, air compressors are essential equipment to ensure normal production. They are also one of the equipment with the highest energy consumption. Under normal circumstances, air compressors can compress air at normal temperature and pressure (0.1MPa) to a pressure of 0.8MPa-1.2MPa. This process consumes a lot of electricity. However, the electricity actually used to compress the air only accounts for 15%-25% of the total electricity consumption. The rest of the electricity is converted into heat energy. In addition to a small amount of heat dissipated through the air compressor body, part of the heat enters the compressed air, causing the temperature of the compressed air to rise, and the other part of the heat is taken away by the lubricating oil in the air compressor, causing the temperature of the lubricating oil to rise.

[0003] Air coolers and oil coolers are installed in air compressors to cool compressed air and lubricating oil respectively. The coolers are generally shell and tube heat exchangers, and the heat obtained from the exchange is directly discharged. The heat in the compressed air and lubricating oil is basically discharged directly into the atmosphere without being recycled or reused, resulting in a waste of resources. Summary of the Invention

[0009] As a further solution of the present invention: a cavity is opened at one end of the recycling cabinet, a rotating motor is fixedly installed inside the cavity, and a rotating shaft is fixedly installed at the output shaft end of the rotating motor, a driving bevel gear is fixedly installed at one end of the rotating shaft, a rotating shaft is rotatably connected inside the cavity, and the rotating shaft passes through the cavity and is fixedly installed with a cam, a driven bevel gear is fixedly installed at one end of the rotating shaft, and the driven bevel gear is meshed with the driving bevel gear.

[0010] As a further solution of the present invention: a cleaning brush is slidably connected to the interior of the recovery cabinet, and the cleaning brush is located directly above the filter plate.

[0011] As a further solution of the present invention: one end of the cleaning brush passes through the cavity and is fixedly installed with a connecting block 2, the cavity is rotatably connected to a rotating main shaft, and the rotating main shaft is rotatably connected to the middle of the connecting block 2 with a connecting arm 2.

[0013] As a further solution of the present invention: a control panel is provided at one end of the compressor body.

[0014] A waste heat recovery method for a waste heat recovery air compressor comprises the following steps:

[0015] S1. First, water is stored in the water storage tank through the water inlet pipe. Then, the electric regulating valve on the periphery of the water discharge pipe 1 is opened through the control panel. The stored water can be introduced into the heat collection cabinet through the water discharge pipe 1. When the compressor body is working, it generates hot air, which is introduced into the heat collection cabinet through the exhaust pipe for collection. The recovered hot air reacts with the water source, cooling the hot air and heating the cold water. Then, the staff activates the electric regulating valve on the periphery of the water discharge pipe 2 through the control panel, allowing the hot water inside the heat collection cabinet to be introduced into the recovery cabinet through the water discharge pipe 2 for recycling. The use of the recovery tank can reduce the waste caused by the direct discharge of hot air through the exhaust pipe. The staff can use the recovered hot water through the drain pipe.

[0016] S2. When the rotating motor starts, it drives the rotating shaft to rotate, and the active bevel gear rotates accordingly. Through the engagement with the driven bevel gear, the rotating shaft rotates, and then drives the cam 1 to rotate. During the rotation of the cam 1, its edge continuously pushes up the connecting arm 1, and the connecting arm 1 is connected to the connecting block 1 at the bottom end of the filter plate, so that the filter plate can sieve left and right within the track defined by the sliding groove and the avoidance groove. At the same time, an elastic sheet is fixedly installed between the bottom end of the filter plate and the two sets of mounting plates inside the recovery cabinet. The elastic sheet assists the filter plate to reset when the cam 1 is not working, thereby enhancing the screening effect of the filter plate, thereby reducing the accumulation of impurities on the upper surface of the filter plate and ensuring the filtering effect.

[0017] S3. When the rotating motor works to rotate the rotating shaft, the worm sleeve rotates accordingly, and through the engagement with the worm wheel, drives the worm wheel to rotate, and the mounting arm rotates with the worm wheel. The rotation of the mounting arm is transmitted to cam 2 through connecting arm 3, causing cam 2 to rotate, and then drives the rotating main shaft to rotate. The rotation of the rotating main shaft drives connecting block 2 and the cleaning brush connected to it to make reciprocating motion above the filter plate through connecting arm 2, cleaning the filter plate and reducing the accumulation of impurities on the filter plate. Cooperating with the function of cam 1 to vibrate and shake off impurities, it further ensures the filtering effect of the filter plate and reduces the occurrence of blockage.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, water is stored in a water storage tank, and an electric regulating valve is operated through a control panel to allow the water to flow to the heat collection cabinet. When the compressor is working, hot air is introduced into the heat collection cabinet through the air outlet pipe, and heat exchange occurs with the water, the hot air is cooled, and the cold water is heated. Then, another electric regulating valve is opened by the control panel to allow the hot water to flow into the recovery cabinet. In this way, the waste heat of the compressor is effectively utilized, and the energy waste caused by the direct discharge of hot air is avoided. The staff can also take the recovered hot water through the drain pipe, realizing efficient energy recovery and utilization.

[0020] In the present invention, the rotating cam continuously drives the connecting arm to rotate, thereby driving the filter plate connected to the connecting arm to move left and right within a specific track. At the same time, the elastic sheet fixed between the bottom end of the filter plate and the mounting plate can assist the filter plate to reset when the cam is not working, thereby enhancing the screening effect, effectively reducing the accumulation of impurities on the filter plate in one place, continuously ensuring the filtering effect of the filter plate, and improving the filtering performance and reliability of the device.

[0021] In the present invention, the engagement of the worm sleeve and the worm wheel is utilized to drive the installation arm, the connecting arm three and the cam two to operate, so that the rotating main shaft rotates, and then the cleaning brush is driven by the connecting arm two to perform a reciprocating sweeping motion above the filter plate, which can effectively reduce the accumulation of impurities on the filter plate in one place. At the same time, in conjunction with the impurity screening function of the cam one, the synergistic effect of cleaning and screening is further ensured, thereby greatly reducing the clogging of the filter plate.

[0041] A waste heat recovery method for a waste heat recovery air compressor comprises the following steps:

[0042] S1. First, water is stored in the water storage tank 7 through the water inlet pipe 8. Then, the electric regulating valve 14 around the outer periphery of the water discharge pipe 12 is opened through the control panel 2. The stored water can be introduced into the heat collection cabinet 6 through the water discharge pipe 12. When the compressor body 1 is working and generates hot air, the hot air is introduced into the heat collection cabinet 6 through the air outlet pipe 4 for collection. The recovered hot air reacts with the water source, cooling the hot air and heating the cold water. Then, the staff activates the electric regulating valve 14 around the outer periphery of the water discharge pipe 2 13 through the control panel 2, so that the hot water inside the heat collection cabinet 6 is introduced into the recovery cabinet 5 through the water discharge pipe 2 13 for recovery. The use of the recovery box 3 can reduce the waste caused by the direct discharge of hot air through the air outlet pipe 4. The staff can use the recovered hot water through the drain pipe 15;

[0043] S2. When the rotating motor 26 is started, it drives the rotating shaft 27 to rotate, and the driving bevel gear 28 rotates accordingly. By meshing with the driven bevel gear 30, the rotating shaft 29 rotates, which in turn drives the cam 20 to rotate. During the rotation of the cam 20, its edge continuously pushes up the connecting arm 21. The connecting arm 21 is connected to the connecting block 22 at the bottom of the filter plate 17, allowing the filter plate 17 to sieve left and right within the track defined by the sliding groove 18 and the avoidance groove 19. At the same time, an elastic sheet 24 is fixedly installed between the bottom end of the filter plate 17 and the two sets of mounting plates 23 inside the recovery cabinet 5. The elastic sheet 24 assists the filter plate 17 in resetting when the cam 20 is not in effect, thereby enhancing the sieving effect of the filter plate 17, thereby reducing the accumulation of impurities on the upper surface of the filter plate 17 and ensuring the filtration effect.

[0044] S3. When the rotating motor 26 is activated to rotate the rotating shaft 27, the worm sleeve 39 rotates accordingly, meshing with the worm gear 35 and driving the worm gear 35 to rotate. The mounting arm 36 then rotates along with the worm gear 35. The rotation of the mounting arm 36 is transmitted to the cam 38 via the connecting arm 37, causing the cam 38 to rotate, which in turn drives the rotating main shaft 33 to rotate. The rotation of the rotating main shaft 33 drives the connecting block 32 and the cleaning brush 31 connected thereto to reciprocate above the filter plate 17 through the connecting arm 2 34, cleaning the filter plate 17 and reducing the accumulation of impurities on the filter plate 17. This, in conjunction with the vibration and shaking off of impurities by the cam 1 20, further ensures the filtering effect of the filter plate 17 and reduces the risk of clogging.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.

The waste heat recovery air compressor according to claim 7, characterized in that: A worm gear (35) is rotatably connected inside the cavity (25), and a worm sleeve (39) is fixedly installed on the outer periphery of the rotating shaft (27), and the worm sleeve (39) is meshed with the worm gear (35). A mounting arm (36) is fixedly installed on one end of the worm gear (35), and a cam 2 (38) is fixedly installed on one end of the rotating main shaft (33), and a connecting arm 3 (37) is rotatably connected to the middle part of the cam 2 (38) and the mounting arm (36).

9. The waste heat recovery air compressor according to claim 7, characterized in that: A control panel (2) is provided at one end of the compressor body (1).

10. A waste heat recovery method according to any one of claims 1 to 9 of the waste heat recovery air compressor, characterized in that: The following steps are involved: S1. First, the water source is stored in the water storage tank (7) through the water inlet pipe (8), and then the electric regulating valve (14) on the periphery of the water discharge pipe (12) is opened through the control panel (2). The stored water source can be introduced into the heat collection cabinet (6) through the water discharge pipe (12). When the compressor body (1) is working and generates hot air, the hot air is introduced into the heat collection cabinet (6) through the air outlet pipe (4) for collection. The recovered hot air reacts with the water source to cool the hot air and heat the cold water. Then, the staff starts the electric regulating valve (14) on the periphery of the water discharge pipe (13) through the control panel (2), so that the hot water inside the heat collection cabinet (6) is introduced into the recovery cabinet (5) through the water discharge pipe (13) for recovery. The recovery box (3) can reduce the phenomenon of waste caused by the outlet pipe (4) directly discharging hot air and the staff can use the recovered hot water through the drain pipe (15); S2. When the rotating motor (26) is started, the rotating shaft (27) is driven to rotate, and the driving bevel gear (28) rotates accordingly. By meshing with the driven bevel gear (30), the rotating shaft (29) is rotated, and the cam (20) is driven to rotate. During the rotation of the cam (20), the edge of the cam (20) continuously pushes up the connecting arm (21). The connecting arm (21) is connected to the connecting block (22) at the bottom end of the filter plate (17), so that the filter plate (17) can be sieved left and right within the track defined by the sliding groove (18) and the avoidance groove (19). At the same time, an elastic sheet (24) is fixedly installed between the bottom end of the filter plate (17) and the two sets of mounting plates (23) inside the recovery cabinet (5). The elastic sheet (24) assists the filter plate (17) to reset when the cam (20) is not in action, thereby enhancing the sieving effect of the filter plate (17), thereby reducing the accumulation of impurities on the upper surface of the filter plate (17) in one place, and ensuring the filtering effect. S3. When the rotating motor (26) is working to rotate the rotating shaft (27), the worm sleeve (39) rotates accordingly, and through engagement with the worm wheel (35), drives the worm wheel (35) to rotate, and the mounting arm (36) rotates along with the worm wheel (35). The rotation of the mounting arm (36) is transmitted to the cam 2 (38) through the connecting arm 3 (37), causing the cam 2 (38) to rotate, thereby driving the rotating main shaft (33) to rotate. The rotation of the rotating main shaft (33) drives the connecting block 2 (32) and the cleaning brush (31) connected thereto to reciprocate above the filter plate (17) through the connecting arm 2 (34), cleaning the filter plate (17) and reducing the accumulation of impurities on the filter plate (17). This cooperates with the function of the cam 1 (20) to shake off impurities by vibration, further ensuring the filtering effect of the filter plate (17) and reducing the occurrence of blockage.
