Description

Technical Field

[0001] This invention relates to the field of compressor technology, specifically to a composite explosion-proof compressor. Background Technology

[0002] Air compressors are commonly used pneumatic power source devices, used to provide compressed high-pressure air for pneumatic tools or for inflating air. The main working principle of existing air compressors is as follows: the compressor is directly driven by an electric motor, causing the crankshaft to rotate, which drives the connecting rod to make the piston reciprocate, causing changes in cylinder volume. Due to the pressure change in the cylinder, air is forced through the intake valve, through the air filter, and into the air tank. During the compression stroke, due to the reduction in the volume of the air tank, the compressed air passes through the exhaust valve, through the exhaust pipe, and through the check valve into the air tank. When the exhaust pressure reaches the rated pressure of 0.7MPa, the compressor automatically stops under the control of a pressure switch. The air compressor's air inlet is located near the ironmaking workshop, where there is a large amount of dust, which easily clogs the air filter, resulting in low intake volume and high exhaust temperature. In addition, the composition of the coking material shows that there is small particulate dust. Dust combined with lubricating oil easily forms sludge and coking, which is not conducive to the cooling of compressed air. Coking material and carbon deposits can cause the exhaust valve to leak, resulting in air leakage and high exhaust temperature, thus creating conditions for high temperature generation.

[0003] Existing composite explosion-proof compressors have structural design flaws, which raise questions about how to perform secondary pressurization of gas to meet the high-pressure gas requirements of current technology, and how to prevent bearing lubricating oil from entering the pressurization chamber, overheating, depositing, and exploding. Summary of the Invention

[0004] This invention provides a composite explosion-proof compressor, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite explosion-proof compressor, comprising...

[0006] The base has a support platform fixedly connected to the top of the base near the edge, a frame fixedly connected to the top of the base near the center, and a motor fixedly connected to the top of the frame.

[0007] The pressurizing mechanism is used to deliver low-pressure airflow from the outside to the inside of the compressor. The airflow is compressed once under the action of centrifugal force. Then, the gas pressurized once is delivered to the secondary pressurizing part for further pressurization. It is located above the support platform. It includes a housing and a lubrication assembly. The lower part of the surface of the housing is fixedly connected to the upper part of the inner side of the support platform. A cooling assembly is fixedly connected to the surface of the housing.

[0012] Preferably, the cooling component includes a component wall, the surface of which is fixedly connected to the surface of the housing, and a heat-conducting wall is fixedly connected to the inner side of the component wall.

[0013] Preferably, a spiral blade is fixedly connected between the component wall and the heat-conducting wall, and a delivery pump is fixedly connected to the surface of the component wall, with the output end of the delivery pump extending to the position between the component wall and the heat-conducting wall.

[0014] Preferably, the explosion-proof mechanism includes a rotating shaft, which is rotatably connected to the inner side of the lubrication component near its end face, and a guide component is fixedly connected to the surface of the rotating shaft near the cooling component.

[0015] Preferably, a variable cross-section screw is fixedly connected to the surface of the rotating shaft, a driving component is fixedly connected to the surface of the cooling component, and an air outlet pipe is fixedly connected to the top of the driving component.

[0016] Preferably, the guiding component includes a second sealing ring, the surface of which is fixedly connected to the inner side of the cooling component. A bearing is fixedly connected to the inner side of the second sealing ring. The guiding component guides the gas, and the external gas is delivered to the housing through the lubrication component. The motor drives the inner side of the component to rotate, which in turn drives the variable cross-section screw to rotate.

[0017] Preferably, a baffle plate is fixedly connected to the surface of the second sealing ring, and a turbine is fixedly connected to the surface of the rotating shaft near the baffle plate. The surface of the rotating shaft is fixedly connected to the inner side of the bearing. The rotating shaft drives the worm gear, the variable cross-section screw and the turbine to rotate respectively. The rotation of the turbine guides air into the interior of the housing.

[0018] Preferably, the driving component includes a connecting wall, the surface of which is fixedly connected to the surface of the cooling component, a worm gear is rotatably connected to the bottom of the inner side of the connecting wall, one end of which is fixedly connected to the output end of the motor, the surface of the barrier plate is fixedly connected to the surface of the second sealing ring, the bearing supports the rotating shaft at the position of the component wall, and the turbine is located inside the housing, drawing in outside air into the housing for compression.

[0019] Preferably, a worm gear is fixedly connected to the middle position of the rotating shaft surface, the surface of the worm gear meshes with the surface of the worm, and an airflow channel is provided between the worm gear and the connecting wall.

[0020] This invention provides a composite explosion-proof compressor. It has the following beneficial effects:

[0021] 1. The compressor of this composite explosion-proof type has a pressurization channel inside the shell. The extension pipe connects to the inside of the bend and the cooling component. The bottom end of the extension pipe does not extend into the inside of the cooling component. After being pressurized, the gas is thrown into the bend. The pressurized gas enters the inside of the cooling component through the extension pipe. In the cooling component, the pressurized gas is pressurized a second time. This solves the problem of how to pressurize the gas a second time to meet the high-pressure gas requirements in the existing technology.

[0022] 2. In this composite explosion-proof compressor, the airflow enters the casing through the barrier and is compressed once. Then, the gas is delivered to the extension pipe, which delivers the pressurized gas to the interior of the heat-conducting wall. The delivery pump delivers cooling water to the interior of the component wall. The input and output of the two delivery pumps make the cooling water circulate. The heat-conducting wall removes the temperature of the pressurized air through the cooling water, preventing the high-pressure air from overheating inside the heat-conducting wall and causing an explosion.

[0023] 3. In this composite explosion-proof compressor, the surface of the variable cross-section screw contacts the inner side of the heat-conducting wall. The air compressed once is introduced into the heat-conducting wall. The variable cross-section screw rotates with the rotating shaft, causing the gas compressed once to be compressed twice. The lubrication components are located outside the housing to prevent lubricating oil from being drawn into the housing. The air is compressed and generates heat, which can easily cause the deposited lubricating oil to coke. This solves the problem of how to prevent bearing lubricating oil from entering the pressurization chamber, overheating, depositing, and exploding.

[0024] 4. In this composite explosion-proof compressor, the rotation of the variable cross-section screw drives the air that has been compressed once. The variable cross-section spiral of the screw causes the air that has been compressed once to be compressed twice. The worm is driven to rotate by the motor. The worm drives the worm wheel to rotate through the tooth surface. The air that has been compressed twice is delivered to the connecting wall by the variable cross-section screw. The high-pressure gas is delivered to the air outlet pipe through the air flow channel and discharged. The motor is located outside the connecting wall, which can effectively prevent the lubricating oil inside the motor from being drawn into the connecting wall and causing deposits.

[0025] 5. In this composite explosion-proof compressor, the inner side of the baffle plate is rotatably connected to the surface of the rotating shaft. The baffle plate can effectively prevent the lubricating oil in the bearing from being drawn into the housing. At the same time, the spiral blades guide the cooling water, and the cooling water forms a directional fluid on the surface of the spiral blades. The direction of this fluid flow is opposite to the direction of the compressed air flow, so that the temperature of the compressed air is effectively carried away, avoiding the internal lubricating oil deposition in the heat-conducting wall, overheating and explosion.

[0038] The pressurizing mechanism 5 is used to deliver low-pressure airflow from the outside to the inside of the compressor. The airflow is compressed once under the action of centrifugal force. Then, the gas that has been pressurized once is delivered to the secondary pressurizing part for further pressurization. It is located above the support platform 2. It includes a housing 51 and a lubrication assembly 53. The lower part of the surface of the housing 51 is fixedly connected to the upper part of the inner side of the support platform 2. A cooling assembly 56 is fixedly connected to the surface of the housing 51. The lubrication assembly 53 supports the rotation of the compressor. The compressed gas enters the housing 51 through the lubrication assembly 53. After being compressed once, the gas enters the cooling assembly 56 and is compressed a second time under the drive of the screw.

[0039] An air inlet duct 52 is fixedly connected to the side of the housing 51 away from the cooling component 56, a bent pipe 54 is fixedly connected to the top of the inner side of the housing 51, and an extension pipe 55 is fixedly connected to the bottom end of the bent pipe 54.

[0040] The explosion-proof mechanism 6 is fixedly connected to the output end of the motor 4 and is used to drive the rotating part of the compressor to rotate, guide the airflow to the housing 51 for primary compression, and then the rotating explosion-proof mechanism 6 performs secondary compression on the gas.

[0042] like Figure 3 , Figure 4 , Figure 5 As shown, the lubrication assembly 53 includes a barrier 531, the surface of which is fixedly connected to the inner side of the air inlet duct 52. A lubrication cylinder 532 is fixedly connected to the side of the barrier 531 away from the air inlet duct 52. A first sealing ring 534 is fixedly connected to the middle of the inner side of the lubrication cylinder 532. A rotor 533 is rotatably connected to the inner side of the lubrication cylinder 532. The inner side of the lubrication cylinder 532 is rotatably connected to the surface of the explosion-proof mechanism 6 through the first sealing ring 534. The cooling assembly 56 includes an assembly wall 561, the surface of which is fixedly connected to the surface of the housing 51. A heat-conducting wall 562 is fixedly connected to the inner side of the assembly wall 561. A spiral blade 563 is fixedly connected between the assembly wall 561 and the heat-conducting wall 562. A delivery pump 564 is fixedly connected to the surface of the assembly wall 561. The output end of the delivery pump 564 extends to the position between the assembly wall 561 and the heat-conducting wall 562.

[0043] In use, the rotating part of the explosion-proof mechanism 6 extends into the interior of the lubrication cylinder 532, which contains lubricating oil that lubricates the rotation of the rotor 533. The first sealing ring 534 prevents the lubricating oil from entering the housing 51 through the rotating part. The airflow enters the housing 51 through the barrier 531 and is compressed once. Subsequently, the gas is delivered to the extension pipe 55, which delivers the pressurized gas to the interior of the heat-conducting wall 562. The delivery pump 564 delivers cooling water to the interior of the component wall 561. The input and output of the two delivery pumps 564 cause the cooling water to circulate. The heat-conducting wall 562 removes the temperature of the pressurized air through the cooling water, preventing the high-pressure air from overheating inside the heat-conducting wall 562 and causing an explosion.

[0044] like Figure 3 , Figure 6As shown, a cooling component 56 is fixedly connected to the surface of the housing 51, and a lubrication component 53 supports the rotation position of the compressor. Compressed gas enters the housing 51 through the lubrication component 53. After being compressed once, the gas enters the cooling component 56 and is compressed a second time under the drive of the screw. An air inlet duct 52 is fixedly connected to the side of the housing 51 away from the cooling component 56. A bent pipe 54 is fixedly connected to the top of the inner side of the housing 51, and an extension pipe 55 is fixedly connected to the bottom end of the bent pipe 54. The explosion-proof mechanism 6 includes a rotating shaft 61. The position of the rotating shaft 61 near its end face is rotatably connected to the inner side of the lubrication component 53. A guide component 62 is fixedly connected to the surface of the rotating shaft 61 near the cooling component 56. A variable cross-section screw 63 is fixedly connected to the surface of the rotating shaft 61. A driving component 64 is fixedly connected to the surface of the cooling component 56, and an air outlet pipe 65 is fixedly connected to the top of the driving component 64.

[0045] In use, the guiding component 62 guides the gas, and the external gas is delivered to the housing 51 through the lubrication component 53. The motor 4 drives the inner side of the driving component 64 to rotate, and the driving component 64 drives the variable cross-section screw 63 to rotate. The surface of the variable cross-section screw 63 contacts the inner side of the heat-conducting wall 562. The air that has been compressed once is introduced into the heat-conducting wall 562. The variable cross-section screw 63 rotates with the rotating shaft 61, so that the gas that has been compressed once is compressed twice. The lubrication component 53 is set outside the housing 51 to prevent lubricating oil from being drawn into the housing 51. The air is compressed and generates heat, which can easily cause the deposited lubricating oil to coke. This solves the problem of how to prevent bearing lubricating oil from entering the pressurization chamber, overheating, depositing and exploding.

[0046] like Figure 6 , Figure 7 , Figure 8 As shown, the guiding component 62 includes a second sealing ring 621. The surface of the second sealing ring 621 is fixedly connected to the inner side of the cooling component 56. A bearing 622 is fixedly connected to the inner side of the second sealing ring 621. A baffle plate 623 is fixedly connected to the surface of the second sealing ring 621. A turbine 624 is fixedly connected to the surface of the rotating shaft 61 near the baffle plate 623. The surface of the rotating shaft 61 is fixedly connected to the inner side of the bearing 622. The driving component 64 includes a connecting wall 641. The surface of the connecting wall 641 is fixedly connected to the surface of the cooling component 56. A worm gear 642 is rotatably connected to the bottom of the inner side of the connecting wall 641. One end of the worm gear 642 is fixedly connected to the output end of the motor 4. A worm wheel 643 is fixedly connected to the middle position of the surface of the rotating shaft 61. The surface of the worm wheel 643 meshes with the surface of the worm gear 642. An airflow channel 644 is provided between the worm wheel 643 and the connecting wall 641.

[0047] In use, the rotating shaft 61 drives the worm gear 643, the variable cross-section screw 63, and the turbine 624 to rotate. The rotation of the turbine 624 guides air into the housing 51. The rotation of the variable cross-section screw 63 drives the air that has been compressed once. The variable cross-section spiral of the screw causes the air that has been compressed once to be compressed a second time. The worm gear 642 is driven to rotate by the motor 4. The worm gear 642 drives the worm wheel 643 to rotate through the tooth surface. The air that has been compressed a second time is delivered to the connecting wall 641 by the variable cross-section screw 63. The high-pressure gas is delivered to the air outlet pipe 65 through the airflow channel 644 and discharged. The motor 4 is set outside the connecting wall 641, which can effectively prevent the lubricating oil inside the motor 4 from being drawn into the connecting wall 641 and causing deposition.

[0048] like Figure 5 , Figure 7 As shown, the surface of component wall 561 is fixedly connected to the surface of housing 51. A heat-conducting wall 562 is fixedly connected to the inner side of component wall 561. A spiral blade 563 is fixedly connected between component wall 561 and heat-conducting wall 562. A delivery pump 564 is fixedly connected to the surface of component wall 561. The output end of delivery pump 564 extends to the position between component wall 561 and heat-conducting wall 562. The surface of second sealing ring 621 is fixedly connected to the inner side of cooling component 56. A bearing 622 is fixedly connected to the inner side of second sealing ring 621. A baffle plate 623 is fixedly connected to the surface of second sealing ring 621. A turbine 624 is fixedly connected to the surface of rotating shaft 61 near baffle plate 623. The surface of rotating shaft 61 is fixedly connected to the inner side of bearing 622.

[0049] In use, the surface of the barrier disk 623 is fixedly connected to the surface of the second sealing ring 621. The bearing 622 supports the rotating shaft 61 at the position of the component wall 561. The turbine 624 is located inside the housing 51 and draws outside air into the housing 51 for compression. The inner side of the barrier disk 623 is rotatably connected to the surface of the rotating shaft 61. The barrier disk 623 can effectively prevent the lubricating oil in the bearing 622 from being drawn into the housing 51. At the same time, the spiral blade 563 guides the cooling water. The cooling water forms a directional fluid on the surface of the spiral blade 563, and the flow direction of this fluid is opposite to the flow direction of the compressed air, so that the temperature of the compressed air is effectively carried away, avoiding the overheating and explosion of the lubricating oil deposited inside the heat-conducting wall 562.
