Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat energy recycling devices, in particular to a heat energy recycling device for an air compressor. BACKGROUND

[0002] An air compressor is a device for compressing gas. When working, gas is first injected into a gas storage tank to achieve a certain pressure value in the gas storage tank. When needed, the gas outlet of the gas storage tank is opened to output high-pressure gas. The air compressor generates a large amount of waste heat during long-term operation. Therefore, the waste heat needs to be recycled and reused to avoid wasting a large amount of heat energy and causing high operating costs. During the recycling of the heat energy of the air compressor, the waste heat is mostly recycled by circulating water. The circulating water is passed into the pipeline to gradually release the heat in the circulating water. The heat released by the circulating water is delivered to the production workshop to increase the temperature of the workshop, thereby solving the problem of low temperature in the workshop in winter and achieving the effect of heat energy recycling.

[0003] The existing circulating water has certain problems during flow. First, a large amount of impurities and the like are generated during the flow of the circulating water. Long-term use can cause blockage of the pipeline and the like, and the cleaning process is very complex, which is not conducive to use. Moreover, the existing circulating water cannot fully contact the side wall of the pipeline during flow, so that the heat in the circulating water cannot be efficiently released, causing certain waste.

[0015] As a further embodiment of the present invention, the cleaning mechanism includes a rotating shaft rotatably mounted on the side of the shaking plate. One end of the rotating shaft passes through the shaking plate, and two annular plates are fixedly sleeved on the rotating shaft. The two annular plates are respectively tightly attached to both sides of the shaking plate, and both annular plates are in rotatable contact with the shaking plate. A transmission fan blade and a cleaning brush are fixedly mounted sequentially from the outside to the inside of one end of the rotating shaft, and the bristles of the cleaning brush are in sliding contact with the filter screen.

[0016] The beneficial effects of this invention are:

[0017] 1. During operation, first connect one end of the L-shaped connecting hole in the regulating valve body to a connecting pipe, and the other end to the feed pipe. The circulating water, heated by the waste heat of the air compressor, is introduced into the feed pipe. The circulating water flows along the L-shaped connecting hole into the connecting pipe, and then into the filter box. The circulating water passes through the filter screen in the mounting frame, filtering impurities. The filtered circulating water flows along the feed pipe into the first bend pipe, and then into the collecting box. After collection, the mixed circulating water flows out through the second bend pipe and the discharge pipe for reuse. The spiral plates installed in the first and second bend pipes effectively dissipate the heat from the circulating water, heating the air in the hot air box. The heated air is then blown out through the air outlet by a fan, raising the workshop temperature and solving the problem of low temperatures in winter.

[0018] 2. When circulating water passes through the installation frame, the force of the circulating water pushes the transmission fan blades to rotate. The transmission fan blades drive the rotating shaft to rotate, and the rotating shaft drives the cleaning brush to rotate along the filter screen. The cleaning brush cleans the impurities attached to the filter screen. At the same time, the drive motor drives the first round shaft to rotate, and the first round shaft drives the drive bevel gear to rotate. The drive bevel gear drives the transmission bevel gear to rotate. With the cooperation of the transmission mechanism and the return spring, the shaking plate vibrates back and forth. The shaking plate drives the filter screen to vibrate back and forth, thereby shaking off the impurities on the filter screen. Through the combination of the cleaning mechanism and the shaking filter assembly, the filter screen can be effectively prevented from being clogged by impurities.

[0019] 3. When the filter mechanism in one filter box needs to be cleaned after filtering circulating water for a long time, the set adjustment mechanism allows the filter mechanisms in the two filter boxes to be used alternately. At this time, the heated circulating water does not flow through the filter box to be cleaned, but changes its path and passes through the cleaned filter box. This causes the locking mechanism to loosen the lock on the filter mechanism to be cleaned, while the locking mechanism locks the cleaned filter mechanism, so that the filter mechanism can be firmly installed in the filter box, thereby enabling continuous and efficient filtration of impurities in the circulating water.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 9 This invention provides a technical solution: an air compressor heat energy recovery and utilization device, including an adjusting seat 1, a spherical groove 11 inside the adjusting seat 1, and circular grooves 12 on three sides of the adjusting seat 1, the circular grooves 12 communicating with the spherical grooves 11. An inlet / outlet adjusting mechanism is installed inside the adjusting seat 1. An inlet pipe 13 is fixedly connected to the outer end of the middle circular groove 12, and connecting pipes 14 are fixedly connected to the outer ends of the two symmetrical circular grooves 12. Filter boxes 2 are fixedly installed at the ends of the two connecting pipes 14 away from the adjusting seat 1. The inner side of each filter box 2 is equipped with a filter mechanism for filtering impurities. The two filter boxes 2 are fixedly installed with feed pipes 23 on the side away from the connecting pipe 14. The two feed pipes 23 are fixedly connected to a hot air box 3. The hot air box 3 is equipped with a heat dissipation mechanism. A fan is fixedly installed at one end of the hot air box 3. The fan consists of a fan motor and fan blades. The fan motor is installed on the side of the hot air box 3. The fan blades are fixedly installed on the motor shaft of the fan motor in a ring array. An air outlet is opened at the end of the hot air box 3 away from the fan. Air guide plates are installed at equal intervals on the inner side of the air outlet.

[0032] Please see Figures 1 to 3 The heat dissipation mechanism includes a collection box 31 fixedly installed on the inner wall of the hot air box 3. Two feed pipes 23 are fixedly connected to a circular plate at one end extending into the inner cavity of the hot air box 3. A set of first bent pipes 32 are fixedly inserted through the side of each of the two circular plates. The ends of the two sets of first bent pipes 32 away from the circular plates are fixedly inserted on the symmetrical sides of the collection box 31. There are multiple sets of first bent pipes 32, and the specific number can be selected according to actual needs. Multiple second bent pipes 33 are fixedly inserted on the side of the collection box 31 away from the inner wall of the hot air box 3. A discharge pipe 34 is fixedly connected to the side of the collection box 31. The ends of the multiple second bent pipes 33 away from the collection box 31 are fixedly inserted into the discharge pipe 34. Spiral plates 321 are fixedly installed on the inner walls of the first bent pipes 32 and the second bent pipes 33.

[0033] A one-way valve is installed at the end of the first bend pipe 32 near the feed pipe 23, so that water can only flow into the first bend pipe 32 along the feed pipe 23, but cannot flow into the feed pipe 23 from the first bend pipe 32.

[0034] The two ends of the first bent pipe 32 are connected to the inner cavity of the feed pipe 23 and the collecting box 31, respectively, and the two ends of the second bent pipe 33 are connected to the inner cavity of the collecting box 31 and the discharge pipe 34, respectively.

[0035] Please see Figure 1 , Figure 2 , Figure 4 and Figure 7 The adjustment mechanism includes an adjustment valve body 4 rotatably installed in a spherical groove 11. An L-shaped connecting hole 41 is opened on the side of the adjustment valve body 4. Rotating shafts 42 are symmetrically fixedly connected to the upper and lower sides of the adjustment valve body 4. The upper end of the upper rotating shaft 42 extends upward through the adjustment seat 1 to the outside and is fixedly sleeved with a gear 43. A rack plate 44 meshes with the side of the gear 43. A limit seat 45 is sleeved on the rack plate 44. The limit seat 45 is fixedly connected to the upper end of the adjustment seat 1. A connecting plate 46 is fixedly connected to one end of the rack plate 44. A fixing plate 47 is fixedly installed on the side of the adjustment seat 1. An electric telescopic rod 48 is fixedly installed on the fixing plate 47. A push plate is fixedly installed at the end of the inner rod of the electric telescopic rod 48. The push plate is fixedly connected to the connecting plate 46. A locking mechanism for locking the filter mechanism is installed on the connecting plate 46.

[0036] The inner rod of the electric telescopic rod 48 extends and retracts, causing the connecting plate 46 to move. The connecting plate 46 causes the rack plate 44 to slide back and forth along the limit seat 45. The rack plate 44 causes the gear 43 to rotate back and forth. The gear 43 rotates at an angle of ninety degrees each time. The gear 43 causes the regulating valve body 4 to rotate along the spherical groove 11 via the rotating shaft 42.

[0037] In the initial state, one end of the L-shaped connecting hole 41 in the regulating valve body 4 is connected to a connecting pipe 14 through a circular groove 12, and the other end of the L-shaped connecting hole 41 is connected to the feed pipe 13 through a circular groove 12. When the gear 43 drives the regulating valve body 4 to rotate 90 degrees through the rotating shaft 42, one end of the L-shaped connecting hole 41 is connected to another connecting pipe 14 through a circular groove 12, and the other end of the L-shaped connecting hole 41 is still connected to the feed pipe 13 through a circular groove 12. This process is repeated so that the two connecting pipes 14 can be used alternately, while the feed pipe 13 can always feed material.

[0038] Heated circulating water is fed into an L-shaped connecting hole 41 through a feed pipe 13. The circulating water then flows into a connecting pipe 14 through the L-shaped connecting hole 41 and the circular groove 12. The water then flows into a filter box 2 through the connecting pipe 14. After the filter mechanism in the filter box 2 filters the impurities in the circulating water, the filtered circulating water flows into the first bent pipe 32 through the feed pipe 23. The circulating water then flows into the collecting box 31 through the first bent pipe 32 and then flows out through the second bent pipe 33 and the discharge pipe 34. The discharge pipe 34 is connected to a water tank through a water pipe. A water inlet pipe is installed on the water tank and is connected to the pump body. The pump body is connected to the spiral pipe. The spiral pipe is installed near the air compressor to absorb the heat emitted by the air compressor. The water is mixed through the collecting box 31 to prevent the heat of the water on the outside that is in contact with the first bent pipe 32 and the second bent pipe 33 from being dissipated, while the heat of the water on the inside is not completely dissipated.

[0039] The spiral plates 321 installed inside the first bend pipe 32 and the second bend pipe 33 allow the circulating water to fully contact the pipe walls of the first bend pipe 32 and the second bend pipe 33, thereby fully dissipating the heat in the circulating water for heating.

[0040] Please see Figure 2 , Figure 4 , Figure 7 and Figure 9 The locking mechanism includes a rectangular sleeve 55 that is inserted through and fixed to the side of the fixed plate 47. A positioning plate 56 is slidably installed inside the rectangular sleeve 55. Locking blocks 57 are symmetrically fixed at both ends of the positioning plate 56. The positioning plate 56 is fixedly connected to the connecting plate 46. The end of the locking block 57 is inserted into the inside of the filter box 2 and engages with the filter mechanism.

[0041] During the reciprocating movement of the connecting plate 46, the positioning plate 56 moves synchronously. The positioning plate 56 slides along the rectangular sleeve 55, thereby enabling the positioning plate 56 to move stably. The positioning plate 56 drives the two locking blocks 57 to move synchronously, thereby enabling the two locking blocks 57 to alternately engage with the filter mechanisms in the two filter boxes 2. That is, when one locking block 57 at one end of the positioning plate 56 engages with the filter mechanism in its adjacent filter box 2, the other locking block 57 at the other end of the positioning plate 56 moves out from its adjacent filter box 2, and the locking block 57 slides in connection with the filter box 2.

[0042] Please see Figure 2 , Figures 4 to 6 , Figure 8 , Figure 9The filtration mechanism includes a mounting frame 5 inserted into the filter box 2 from top to bottom. The two inner side walls of the mounting frame 5 are symmetrically provided with sliding grooves 51. The two outer side walls of the mounting frame 5 are symmetrically fixedly connected with strip-shaped inserts 52. The side of one strip-shaped insert 52 near the positioning plate 56 is provided with a groove 53. The inner side of the groove 53 is fixedly connected with a locking block 54. The end of the locking block 57 is provided with a locking groove, which engages with the locking block 54.

[0043] A shaking filter assembly is installed on the inner side of the mounting frame 5. A transmission mechanism is installed on the side of the shaking filter assembly. A concave plate 6 is arranged between the two transmission mechanisms. The concave plate 6 is located between the two filter boxes 2. The upper end of the concave plate 6 is fixedly connected to one end of the fixing plate 47. A first round shaft 61 is rotatably installed on the inner side of the concave plate 6. One end of the first round shaft 61 extends sequentially into the inner cavity of the hot air box 3 and the collecting box 31. The first round shaft 61 is rotatably connected to the hot air box 3 and the collecting box 31 respectively. Multiple stirring plates 63 are fixedly connected in a ring array at the end of the first round shaft 61 that extends into the inner cavity of the collecting box 31. A drive bevel gear 62 is fixedly sleeved on the first round shaft 61. The first round shaft 61 is driven by the output shaft of the drive motor fixedly installed on the side of the concave plate 6. A cleaning mechanism is installed on the shaking filter assembly.

[0044] The output shaft of the drive motor drives the first round shaft 61 to rotate, and the first round shaft 61 drives the stirring plate 63 to rotate, so that the circulating water collected in the collection tank 31 is fully mixed by the stirring plate 63.

[0045] The upper end of the filter box 2 is provided with a mounting groove 21, and guide slots 22 are symmetrically provided on both sides of the mounting groove 21. The mounting frame 5 is movably inserted into the mounting groove 21. The mounting frame 5 passes through the mounting groove 21 and is inserted into the inner cavity of the filter box 2. The lower end of the mounting frame 5 contacts the bottom of the inner cavity of the filter box 2. The strip plate 52 is inserted into the guide slot 22.

[0046] The strip plate 52 in the filter mechanism is locked by a locking block 57 on the positioning plate 56. At this time, the filter mechanism cannot move and can be firmly installed in the filter box 2. At the same time, the circulating water flows into the filter box 2 with the filter mechanism fixedly installed along the connecting pipe 14, so that the filter mechanism can stably filter impurities in the circulating water. Meanwhile, another locking block 57 on the positioning plate 56 separates from the other filter box 2. At this time, the filter mechanism in the filter box 2 can be pulled up along the mounting groove 21, so that the filter mechanism can be easily cleaned and maintained. By setting up two filter boxes 2 and filter mechanisms to be used alternately, the impurities in the circulating water can be continuously and efficiently filtered.

[0047] Please see Figure 8 and Figure 9The shaking filter assembly includes a shaking plate 7 that is slidably installed in the mounting frame 5. The side of the shaking plate 7 has multiple fan-shaped grooves 71 arranged in a ring array. A filter screen 72 is fixedly installed on one side of each fan-shaped groove 71. Slide plates 73 are symmetrically fixedly connected to both sides of the shaking plate 7. A slide rod 74 is inserted through the side of the slide plate 73. The slide rod 74 is set in the slide groove 51. A return spring 75 is sleeved on the slide rod 74. The transmission mechanism is installed on the side of the shaking plate 7 away from the connecting pipe 14. The cleaning mechanism is installed on the shaking plate 7.

[0048] The slide plate 73 is slidably connected to the slide groove 51 and the slide rod 74 respectively. The two ends of the slide rod 74 are fixedly connected to the two side walls of the slide groove 51 respectively. The two ends of the return spring 75 abut against the slide groove 51 and the shaking plate 7 respectively. The filter screen 72 is set on the side of the shaking plate 7 near the connecting pipe 14. The return spring 75 is set on the side of the slide plate 73 near the connecting pipe 14.

[0049] Please see Figure 6 and Figure 9 The transmission mechanism includes a second round shaft 65 rotatably mounted inside the filter box 2. Two cams 66 are fixedly sleeved on the second round shaft 65. One end of the second round shaft 65 passes through the filter box 2 and extends to the inner side of the concave plate 6. The second round shaft 65 is rotatably connected to the filter box 2 and the concave plate 6 respectively. Two limiting rings are fixedly sleeved on the second round shaft 65. The two limiting rings are rotatably in contact with the inner wall of the filter box 2 respectively. A transmission bevel gear 64 is fixedly connected to the end of the second round shaft 65 extending to the inner side of the concave plate 6. The transmission bevel gear 64 meshes with the drive bevel gear 62. The sides of the two cams 66 are slidably in contact with isosceles trapezoidal plates 76. The two isosceles trapezoidal plates 76 are fixedly connected to the vibrating plate 7.

[0050] When the first circular shaft 61 rotates, it drives the drive bevel gear 62 to rotate, the drive bevel gear 62 drives the transmission bevel gear 64 to rotate, the transmission bevel gear 64 drives the second circular shaft 65 to rotate, and the second circular shaft 65 drives the two cams 66 on it to rotate.

[0051] When the protrusion of the cam 66 contacts the isosceles trapezoidal plate 76, the cam 66 pushes the isosceles trapezoidal plate 76 to move inward to the mounting frame 5. The isosceles trapezoidal plate 76 drives the shaking plate 7 to move inward to the mounting frame 5. The shaking plate 7 drives the sliding plates 73 on both sides to slide along the slide groove 51 and the slide rod 74. At the same time, the sliding plates 73 squeeze the return spring 75.

[0052] When the protrusion of cam 66 moves away from the isosceles trapezoidal plate 76, the return spring 75 pushes the slide plate 73 to slide back. The slide plate 73 drives the vibrating plate 7 to move outward along the mounting frame 5. As cam 66 continues to rotate, the vibrating plate 7 vibrates back and forth. The vibrating plate 7 drives the filter screen 72 to vibrate back and forth, thereby shaking off the impurities on the filter screen 72 and preventing the impurities from clogging the filter screen 72.

[0053] Please see Figure 2 , Figure 8 and Figure 9 The cleaning mechanism includes a rotating shaft 8 rotatably mounted on the side of the shaking plate 7. One end of the rotating shaft 8 passes through the shaking plate 7. Two annular plates are fixedly sleeved on the rotating shaft 8. The two annular plates are respectively tightly attached to both sides of the shaking plate 7, and both annular plates are in rotatable contact with the shaking plate 7. A transmission fan blade 82 and a cleaning brush 81 are fixedly mounted from the outside to the inside at one end of the rotating shaft 8. The transmission fan blade 82 and the cleaning brush 81 are both located on the same side of the shaking plate 7 as the filter screen 72. The bristles of the cleaning brush 81 are in sliding contact with the filter screen 72.

[0054] When circulating water passes through the filter box 2, it flows along the inner side of the mounting frame 5. At this time, the filter screen 72 filters the impurities in the circulating water. Simultaneously, the force of the circulating water drives the drive fan blade 82 to rotate. The drive fan blade 82 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the cleaning brush 81 to rotate along the filter screen 72. The cleaning brush 81 cleans the impurities attached to the filter screen 72, further preventing impurities from clogging the mesh of the filter screen 72, so that the filter screen 72 can continuously filter the circulating water.

[0055] Working principle: During operation, one end of the L-shaped connecting hole 41 in the regulating valve body 4 is connected to a connecting pipe 14, and the other end is connected to the feed pipe 13. The circulating water heated by the waste heat of the air compressor is introduced into the feed pipe 13. The circulating water flows into the connecting pipe 14 along the L-shaped connecting hole 41, and then into the filter box 2 along the connecting pipe 14. The circulating water passes through the filter screen 72 in the mounting frame 5. The filter screen 72 filters the impurities in the circulating water. At the same time, the force of the circulating water pushes the transmission fan blade 82 to rotate. The transmission fan blade 82 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the cleaning brush 81 to rotate along the filter screen 72. The cleaning brush 81 cleans the impurities attached to the filter screen 72.

[0056] At this time, the drive motor drives the first round shaft 61 to rotate, the first round shaft 61 drives the drive bevel gear 62 to rotate, the drive bevel gear 62 drives the transmission bevel gear 64 to rotate, the transmission bevel gear 64 drives the second round shaft 65 to rotate, and the second round shaft 65 drives the two cams 66 on it to rotate. When the protrusion of the cam 66 contacts the isosceles trapezoidal plate 76, the isosceles trapezoidal plate 76 drives the shaking plate 7 to move inward to the mounting frame 5, and the shaking plate 7 drives the slide plate 73 to squeeze the return spring 75. When the protrusion of the cam 66 moves away from the isosceles trapezoidal plate 76, under the action of the return spring 75, the slide plate 73 pushes the slide plate 73 to slide back, and the slide plate 73 drives the shaking plate 7 to move outward along the mounting frame 5. Through the continuous rotation of the cam 66, this process is repeated, so that the shaking plate 7 shakes back and forth. The shaking plate 7 drives the filter screen 72 to shake back and forth, thereby shaking off the impurities on the filter screen 72 and preventing the impurities from clogging the filter screen 72.

[0057] The filtered circulating water flows into the first bend pipe 32 along the feed pipe 23. After flowing into the collection box 31 along the first bend pipe 32, the circulating water is stirred by the stirring plate 63 driven by the first round shaft 61 to prevent the water from separating into hot and cold layers. This prevents the heat of the water on the outside that is in contact with the first bend pipe 32 and the second bend pipe 33 from dissipating, while the heat of the water on the inside is not completely dissipated. The mixed circulating water then flows out along the second bend pipe 33 and the discharge pipe 34 for reuse. The spiral plates 321 installed in the first bend pipe 32 and the second bend pipe 33 ensure that the circulating water can fully contact the pipe walls of the first bend pipe 32 and the second bend pipe 33, thereby fully dissipating the heat in the circulating water for heating. The dissipated heat heats the air in the hot air box 3, and the heated air is then blown out through the air outlet by the fan and blown into the production workshop to raise the workshop temperature and solve the problem of low temperature in the workshop in winter.

[0058] When the filter mechanism in a filter box 2 needs to be cleaned after filtering the circulating water for a long time, the inner rod of the electric telescopic rod 48 extends and retracts, causing the connecting plate 46 to move. The connecting plate 46 causes the rack plate 44 to move, which in turn causes the gear 43 to rotate 90 degrees. The gear 43 then causes the regulating valve body 4 to rotate 90 degrees along the spherical groove 11 via the rotating shaft 42.

[0059] One end of the L-shaped connecting hole 41 in the regulating valve body 4 is connected to another connecting pipe 14, while the other end of the L-shaped connecting hole 41 is still connected to the feed pipe 13. At this time, the heated circulating water flows into another filter box 2 along the feed pipe 13, the L-shaped connecting hole 41, and the connecting pipe 14. The filter mechanism in the filter box 2 continues to filter the impurities in the circulating water, so that the filter mechanisms in the two filter boxes 2 can be used alternately, thereby continuously and efficiently filtering the impurities in the circulating water.

[0060] As the connecting plate 46 moves, it drives the positioning plate 56 to move synchronously. The positioning plate 56 drives the two locking blocks 57 to move synchronously. At this time, one locking block 57 at one end of the positioning plate 56 moves out of the filter box 2 to be cleaned, so that the locking block 57 releases the lock on the filter mechanism to be cleaned, and the filter mechanism to be cleaned can move upward along the mounting groove 21, so that it can be easily cleaned.

[0061] At the same time, when a locking block 57 at one end of the positioning plate 56 engages with the filter mechanism in the adjacent filter box 2, a locking block 57 at the other end of the positioning plate 56 is inserted into the cleaned filter box 2. Simultaneously, the locking block 57 engages with the locking block 54 in the cleaned filter mechanism, thereby locking the filter mechanism and ensuring that the filter mechanism can be firmly installed in the filter box 2.
