Description

Technical Field

[0001] The present invention relates to the field of liquid variable volume machinery, and specifically relates to a diaphragm compressor. Background Art

[0002] A diaphragm compressor is a device for compressing objects, which can be used in the environmental protection field to compress garbage and high-moisture coal cinder in coal mines. Through the compression of gas, the objects can achieve the effect of solid-liquid separation. The diaphragm machine belongs to a positive displacement compressor, and it realizes the compression of gas by changing the volume of the gas chamber through the deformation of the diaphragm;

[0003] The existing Chinese patent with the publication number CN115095510B discloses a diaphragm compressor, belonging to the technical field of compressors, including a compressor housing. Connecting flanges are respectively provided at both ends of the compressor housing. Covers are respectively connected to the two connecting flanges. Fixing bolts are threadedly connected in the covers and the connecting flanges to fix the two. A diaphragm chamber is formed between the cover and the connecting flange. A diaphragm group is provided between the cover and the connecting flange in the diaphragm chamber. A limiting plate is provided on the side of the diaphragm group close to the connecting flange in the diaphragm chamber; the device combines two-stage compressors into one device, which can avoid the problem of the large volume of two devices connected in series, improve the compression ratio of the device, meet higher usage requirements, reduce resource consumption, and is convenient to adjust;

[0004] 1. This diaphragm compressor still has the following defects: After the compressor completes the compression of the gas, it is necessary to bottle the gas for easy use (such as compressing high-moisture coal cinder in coal mines). When the traditional compressor compresses the gas and bottles the gas at the same time, it requires two power sources, resulting in a high cost. The kinetic energy of the device can only be used for compression, and the force generated when the rotating rod rotates has no other additional effects; moreover, the degree of intelligence of the two steps of gas compression and bottling by the compressor is relatively low, and manual assistance is required;

[0005] 2. This diaphragm compressor also has the following defects. First, improving the compression ratio requires higher kinetic energy of the motor. Otherwise, after installing the two-stage compressor, the resistance on the motor is greater, the wear of the motor is greater, and it may even be unable to start working. Summary of the Invention

[0006] The purpose of the present invention is to provide a diaphragm compressor to solve the problems raised in the above background art.

[0007] The technical solution of the present invention is: A diaphragm compressor, including a workbench surface and an air filling tank. One side of the top of the workbench surface is provided with a compressor mechanism, and the compressor mechanism produces and transports compressed gas. The other side of the workbench surface is provided with a transportation component, and the transportation component transports the air filling tank to the side of the diaphragm compression component.

[0012] Further, an oil storage cylinder body is installed on one side of the driving motor, and a compressor housing is installed on one side of the oil storage cylinder body, and

[0013] The output end of the driving motor is connected to a hollow rotating rod. The hollow rotating rod rotates around the central axis of the oil storage cylinder body, and a connecting piece is connected to one side of the hollow rotating rod. One end of the connecting piece is connected to a telescopic piston. When the connecting piece rotates, it drives the telescopic piston to expand and contract inside the compressor housing.

[0014] Further, an oil storage cavity is provided at the top end inside the compressor housing, and an oil inlet valve is connected to one side of the oil storage cavity, and an oil outlet valve is connected to the other side of the oil storage cavity.

[0015] Further, an air storage cavity is provided at one end of the oil storage cavity, and a metal diaphragm is installed at the connection between the oil storage cavity and the air storage cavity. The metal diaphragm compresses the gas through deformation. A filter screen is provided on one side of the oil storage cavity close to the metal diaphragm, and

[0016] An air inlet valve is connected to one side of the air storage cavity, and an air outlet valve is connected to one end of the air storage cavity.

[0017] Further, a second transmission gear is installed at the output end of the drive motor, and a telescopic transmission belt is in contact connection with the surface of the second transmission gear. A winding and unwinding reel is arranged on one side of the telescopic transmission belt. A third transmission gear is installed at the bottom end of the telescopic transmission belt, and a transmission roller shaft is installed at one end of the third transmission gear. A first transmission gear disc is installed on the side of the transmission roller shaft away from the third transmission gear.

[0018] Further, the transportation component is installed on one side of the diaphragm compression component. The transportation component includes:

[0019] A protective housing installed at the top end of the workbench surface. There are multiple groups of the protective housing, and a diversion groove is arranged between every two groups of the protective housing, and

[0020] Multiple transmission roller shafts are installed inside the protective housing, and the transmission roller shafts can drive the gas charging tank to move.

[0021] Further, a first transmission gear is installed at the bottom end of the transmission roller shaft at the end of the protective housing, and there are multiple groups of the first transmission gears. The multiple groups of the first transmission gears are driven by a transmission tooth track.

[0022] Further, the quick-release connection component includes:

[0023] Fixed insertion rods are installed on both sides of the first transmission gear close to the telescopic transmission belt. An internally threaded sliding sleeve is fixed at the bottom end of the fixed insertion rod, and a telescopic screw rod is arranged inside the internally threaded sliding sleeve.

[0026] Further, one end of the suction valve and the exhaust valve away from the compressor housing is connected to an opening and closing controller, and one end of the opening and closing controller away from the suction valve and the exhaust valve is connected to a filter. An air transmission pipeline interface is connected to one side of the opening and closing controller, and the output end of the filter is connected to the air transmission pipeline interface.

[0027] The present invention provides a diaphragm compressor through improvement. Compared with the prior art, the following improvements and advantages are achieved:

[0028] First, by transporting the compressed gas in bottles, the gas can be carried. The compressor mechanism enables the transportation component and the diaphragm compression component to use the same power source, the drive motor, through the cooperation of the transmission component and the quick-release connection component. It can not only be used to compress gas, but also convert the rotational force in the hydraulic cylinder into a transmission force for the transportation component. When the gas compressed by the diaphragm compression component is sufficient during use, the transportation component will start to drive the gas cylinder to move, transporting the gas cylinder filled with gas away, achieving the effects of linkage and saving motor costs;

[0029] Second, the diaphragm compression component compresses the gas. When the hydraulic cylinder in the diaphragm compression component compresses enough gas, the drive motor drives the drive roller to rotate through the second transmission gear, the telescopic conveyor belt, and the third transmission gear. The drive roller drives the first drive gear disk to rotate, and the first drive gear disk drives the second drive gear disk to rotate through gear transmission. Since there is a thread inlaid at the connection between the internal thread sleeve and the telescopic screw, when the telescopic screw rotates, it will drive the bottom transmission component to rise. When the limit slot at the top of the telescopic screw engages with the connection rod, it can drive the first transmission gear to rotate. The first transmission gear drives multiple groups of first transmission gears to rotate simultaneously through the transmission tooth track. The rotation of the first transmission gear will drive the transmission roller shaft connected to the top to rotate. There is a drive roller at the bottom of the transmission roller shaft. The drive rollers at the bottom of each group of transmission roller shafts are driven by a track, and multiple groups of transmission roller shafts drive the gas cylinder to move through the same-frequency and same-direction rotation, achieving the effect of transporting the gas cylinder. This mechanism can also transport the compressed filling gas during gas compression through transmission;

[0030] Among them, the diaphragm compression component compresses the gas through the reciprocating motion of the metal diaphragm. When the piston is at the outer dead center, the metal diaphragm deforms under the action of the pressure oil and adheres tightly to the cylinder head surface. The gas in the air storage chamber has been discharged, but due to the remaining clearance volume, there is still high-pressure residual gas. When the telescopic piston in the oil cylinder moves towards the inner dead center, the oil pressure in the oil storage chamber gradually decreases until it disappears, and a pressure difference appears on both sides of the metal diaphragm. The metal diaphragm begins to retract and deform under the action of the gas residual pressure and its own deformation force. The volume of the air storage chamber increases, and the air pressure begins to decrease. When the air pressure in the chamber is less than the pressure of the gas to be sucked, the suction valve automatically opens, and the suction process begins. When the telescopic piston continues to move towards the inner dead center, the metal diaphragm continues to deform towards the oil storage chamber side under the pressure difference. When the telescopic piston in the oil cylinder moves to the inner dead center position, the metal diaphragm deforms to the lower limit position and the suction valve closes, and the suction process ends. When the telescopic piston starts to move towards the outer dead center, the oil pressure begins to increase, the metal diaphragm deforms towards the outer dead center, the volume of the air storage chamber gradually becomes smaller, and when the gas pressure in the air storage chamber is greater than the air pressure in the exhaust pipe, the exhaust valve opens, and the compression process is completed and the gas is discharged until the telescopic piston in the oil cylinder is compressed to the outer dead center. When the metal diaphragm adheres tightly to the cylinder head, the suction valve closes, and the exhaust process ends. Thus, a working cycle is completed;

[0031] Among them, the output gas is transported to the gas transmission pipeline interface through the exhaust valve and filled in the inflatable tank. The function of the opening and closing controller installed in the middle of the pipeline is to open and close the pipeline. The function of the filter is to filter the compressed gas. When transporting the gas, the second transmission gear is always rotating. When the telescopic screw rises and the connecting plug rod and the telescopic screw are engaged, the inflatable tank is filled with gas. At the same time, the transportation component is activated, which can drive the inflatable tank to move. The function of filling the gas is to facilitate the gas to be carried and used on site. It can also be used at landfills and coal mine sites. When in use, the compressed filled gas is injected into the tank containing garbage and high-moisture coal cinder. The bottom of the tank containing garbage and high-moisture coal cinder is provided with a filter screen, which can separate the solid and liquid of the garbage and high-moisture coal cinder after the gas in the inflatable tank is filled.

Detailed implementation mode

[0045] The following will be combined with the attached Figures 1 to 11 The present invention will be described in detail. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0046] The present invention provides a diaphragm compressor through improvement. As Figures 1 - 11 shown in the figure, a diaphragm compressor includes a workbench surface 1 and a gas filling tank 3. The function of the gas filling tank 3 is to facilitate gas carrying and make it convenient to be taken to the site for use. It can also be used at landfills and coal mine sites. When in use, the compressed filling gas is injected into the tank containing garbage and high-water-content coal cinder. A filter screen is provided at the bottom of the tank containing garbage and high-water-content coal cinder. When the gas in the gas filling tank 3 is filled in, the garbage and high-water-content coal cinder can be subjected to solid-liquid separation treatment;

[0047] One side of the top of the workbench surface 1 is provided with a compressor mechanism 6. Through transmission, the compressed gas is bottled and transported, so that the gas can be carried. The compressor mechanism 6 produces and transports the compressed gas. On the other side of the workbench surface 1, a transportation component 2 is installed, and the transportation component 2 transports the gas filling tank 3 to the side of the diaphragm compression component 4.

[0048] The transportation component 2 is installed on one side of the diaphragm compression component 4. The transportation component 2 includes:

[0049] The protective housing 201 is installed at the top of the workbench 1. There are multiple groups of protective housings 201. A diversion channel 202 is provided between every two groups of protective housings 201. And,

[0050] Multiple groups of transmission roller shafts 203 are installed inside the protective housing 201. A transmission roller is provided at the bottom end of the transmission roller shaft 203. The transmission rollers at the bottom ends of each group of transmission roller shafts 203 are driven by a crawler. The multiple groups of transmission roller shafts 203 drive the gas filling tank 3 to move through rotation in the same frequency and direction, achieving the function of transporting the gas filling tank 3. This mechanism can also transport the compressed filling gas during gas compression through transmission.

[0051] A first transmission gear 205 is installed at the bottom end of the transmission roller shaft 203 at the end of the protective housing 201. The rotation of the first transmission gear 205 drives the rotation of the transmission roller shaft 203 connected to the top. And there are multiple groups of first transmission gears 205. The multiple groups of first transmission gears 205 are driven by a transmission gear crawler 206. The first transmission gear 205 drives the multiple groups of first transmission gears 205 to rotate simultaneously through the transmission gear crawler 206;

[0052] Among them, the compressor mechanism 6 includes:

[0053] A diaphragm compression assembly 4, which is installed on one side of the top of the workbench 1. The gas is compressed by the diaphragm compression assembly 4. When the hydraulic cylinder in the diaphragm compression assembly 4 compresses enough gas, and a protective fence 5 is installed on one side of the diaphragm compression assembly 4. The gas compressed by the diaphragm compression assembly 4 is transmitted to the inside of the gas filling tank 3 through the gas transmission pipeline interface 408, and the gas bottling is completed through the gas filling tank 3. The diaphragm compression assembly 4 includes a drive motor 402, and the drive motor 402 is installed on the top of the workbench 1. The drive motor 402 serves as the power source of the device; And

[0054] An oil storage cylinder body 403 is installed on one side of the drive motor 402, and a compressor housing 401 is installed on one side of the oil storage cylinder body 403. And

[0055] The output end of the drive motor 402 is connected to a hollow rotating rod 410. The hollow rotating rod 410 rotates around the center line support shaft 409 of the oil storage cylinder body 403. And a connecting piece 411 is connected to one side of the hollow rotating rod 410. One end of the connecting piece 411 is connected to a telescopic piston 412. When the connecting piece 411 rotates, it drives the telescopic piston 412 to expand and contract inside the compressor housing 401;

[0056] At the top inside the compressor housing 401, there is an oil storage chamber 413. One side of the oil storage chamber 413 is connected to an oil inlet valve 415, and the other side of the oil storage chamber 413 is connected to an oil outlet valve 414. The oil outlet valve 414 and the oil inlet valve 415 are communicated with the oil chamber in the oil storage cylinder body 403 through a diversion pipe. On one side inside the oil storage cylinder body 403, a stable push spring 419 is installed, and the stable push spring 419 is connected to the side of the hollow rotating rod 410.

[0057] One end of the oil storage chamber 413 is provided with an air storage chamber 418. A metal diaphragm 417 is installed at the connection between the oil storage chamber 413 and the air storage chamber 418. The metal diaphragm 417 compresses the gas through deformation. On the side of the oil storage chamber 413 close to the metal diaphragm 417 inside, there is an oil filter screen 416, and

[0058] One side of the air storage chamber 418 is connected to an air inlet valve 404, and one end of the air storage chamber 418 is connected to an exhaust valve 405.

[0059] When the telescopic piston 412 is at the outer dead center, the metal diaphragm 417 deforms under the action of the pressure oil and tightly adheres to the cylinder head surface. The gas in the air storage chamber 418 has been discharged, but due to the clearance volume, there is still high-pressure residual gas. When the telescopic piston 412 in the oil cylinder moves towards the inner dead center, the oil pressure in the oil storage chamber 413 gradually decreases until it disappears. A pressure difference appears on both sides of the metal diaphragm 417. The metal diaphragm 417 begins to retract and deform under the action of the gas residual pressure and its own deformation force. The volume of the air storage chamber 418 increases, and the air pressure begins to decrease. When the air pressure in the chamber is less than the pressure of the gas to be sucked, the air inlet valve 404 automatically opens, and the suction process begins. When the telescopic piston 412 continues to move towards the inner dead center, the metal diaphragm 417 continues to deform towards the oil storage chamber 413 side under the pressure difference. When the telescopic piston 412 in the oil cylinder moves to the inner dead center position, the metal diaphragm 417 deforms to the lower limit position and the air inlet valve 404 closes, and the suction process ends. When the telescopic piston 412 begins to move towards the outer dead center, the oil pressure begins to increase, the metal diaphragm 417 deforms towards the outer dead center direction, the volume of the air storage chamber 418 gradually becomes smaller. When the gas pressure in the air storage chamber 418 is greater than the air pressure in the exhaust pipeline, the exhaust valve 405 opens, and the compression process is completed and the gas is discharged until the telescopic piston 412 in the oil cylinder moves to the outer dead center. When the metal diaphragm 417 tightly adheres to the cylinder head, the air inlet valve 404 closes, and the exhaust process ends. Thus, a working cycle is completed.

[0060] One end of the intake valve 404 and the exhaust valve 405, which is far from the compressor housing 401, is connected to an opening and closing controller 406. The function of the opening and closing controller 406 installed in the middle of the pipeline is to open and close the pipeline. One end of the opening and closing controller 406, which is far from the intake valve 404 and the exhaust valve 405, is connected to a filter 407. The function of the filter 407 is to filter the compressed gas. One side of the opening and closing controller 406 is connected to a gas transmission pipeline interface 408. The output end of the filter 407 is connected to the gas transmission pipeline interface 408; the output gas is transported to the gas transmission pipeline interface 408 through the exhaust valve 405 and filled in the inflatable tank 3;

[0061] The diaphragm compression assembly 4 belongs to a positive displacement compressor. It compresses the gas by changing the volume of the gas storage chamber 418 through the deformation of the metal diaphragm 417. A curved surface is machined on each of the cylinder head and the oil distribution disc of the diaphragm machine head. Together with the metal diaphragm 417 clamped between them, they respectively form the gas storage chamber 418 and the oil storage chamber 413. The gas storage chamber 418 at the top of the metal diaphragm 417 is communicated with the intake valve 404 and the exhaust valve 405 installed in the valve holes of the cylinder head, while the oil storage chamber 413 is communicated with the oil chamber in the oil storage cylinder body 403 through the oil outlet valve 414 and the oil inlet valve 415 on the oil distribution disc. In addition, the bolts around the machine head fasten the cylinder head, the diaphragm, the oil distribution disc and the cylinder body together, so that the gas chamber and the oil chamber in the machine head are sealed and do not leak;

[0062] The transmission assembly 7 is installed at the bottom end of the diaphragm compression assembly 4 and is driven by the diaphragm compression assembly 4. The transmission assembly 7 penetrates the workbench surface 1 and extends below the workbench surface 1; and

[0063] A second transmission gear 701 is installed at the output end of the drive motor 402. The second transmission gear 701 is always rotating when transporting gas. The surface of the second transmission gear 701 is in contact connection with a telescopic transmission belt 702. A winding and unwinding reel is provided on one side of the telescopic transmission belt 702. A third transmission gear 703 is installed at the bottom end of the telescopic transmission belt 702. One end of the third transmission gear 703 is installed with a transmission roller shaft 704. The drive motor 402 drives the transmission roller shaft 704 to rotate through the second transmission gear 701, the telescopic transmission belt 702 and the third transmission gear 703. A first transmission gear disc 705 is installed on the side of the transmission roller shaft 704 far from the third transmission gear 703. The transmission roller shaft 704 drives the first transmission gear disc 705 to rotate,

[0064] The quick-release connection assembly 8 is installed on one side of the transmission assembly 7 and is driven by the transmission assembly 7. The quick-release connection assembly 8 is used to connect the transmission assembly 7 and the transportation assembly 2 to realize the timed transmission of the inflatable tank 3;

[0065] The quick-release connection assembly 8 includes:

[0066] Fixed insertion rod 801 is installed on both sides of the first transmission gear 205 of the telescopic conveyor belt 702 near it. The bottom end of the fixed insertion rod 801 is fixed with an internally threaded sliding sleeve 802, and an expansion screw 803 is arranged inside the internally threaded sliding sleeve 802. The expansion screw 803 and the internally threaded sliding sleeve 802 are in threaded transmission. Because threads are inlaid at the connection of the internally threaded sliding sleeve 802 and the expansion screw 803, when the expansion screw 803 rotates, it will drive the transmission assembly 7 at the bottom end to rise.

[0067] A limit slot 806 is inlaid at the top end of the expansion screw 803. A connection insertion rod 805 is fixed at the bottom end of the first transmission gear 205 near the telescopic conveyor belt 702, and a convex block is inlaid on one side of the connection insertion rod 805. A groove is inlaid on one side of the limit slot 806. The connection insertion rod 805 and the limit slot 806 are in snap connection; when the expansion screw 803 rises and the connection insertion rod 805 is engaged with the expansion screw 803, it can drive the first transmission gear 205 to rotate. At this time, the gas tank 3 is filled with gas, and at the same time, the transportation assembly 2 is started, and it can drive the gas tank 3 to move.

[0068] The bottom end of the expansion screw 803 is fixed with a second transmission gear disc 804, and the second transmission gear disc 804 and the first transmission gear disc 705 are in a meshing transmission relationship. The first transmission gear disc 705 drives the second transmission gear disc 804 to rotate through gear transmission. When the expansion screw 803 rises, the take-up and pay-off reel on one side of the telescopic conveyor belt 702 automatically contracts.

[0069] The compressor mechanism 6 enables the transportation assembly 2 and the diaphragm compression assembly 4 to use the same power source, the drive motor 402, through the cooperation of the transmission assembly 7 and the quick-release connection assembly 8. It can not only be used to compress gas, but also convert the rotational force in the hydraulic cylinder into the transmission force on the transportation assembly 2. When the gas compressed by the diaphragm compression assembly 4 is sufficient during use, the transportation assembly 2 will be started to drive the gas tank 3 to move and transport away the gas tank 3 filled with gas, achieving the functions of linkage and saving the motor cost.

[0070] Working principle: First, the diaphragm compression assembly 4 compresses the gas. When the hydraulic cylinder in the diaphragm compression assembly 4 has compressed enough gas, the drive motor 402 drives the drive roller shaft 704 to rotate through the second transmission gear 701, the telescopic conveyor belt 702 and the third transmission gear 703. The drive roller shaft 704 drives the first drive gear disc 705 to rotate. The first drive gear disc 705 drives the second drive gear disc 804 to rotate through gear transmission. Since there is a thread inlay at the connection between the internal thread sliding sleeve 802 and the telescopic screw rod 803, when the telescopic screw rod 803 rotates, it will drive the drive assembly 7 at the bottom to rise. When the limit slot 806 at the top of the telescopic screw rod 803 is engaged with the connecting plug rod 805, it can drive the first transmission gear 205 to rotate. The first transmission gear 205 drives multiple groups of first transmission gears 205 to rotate simultaneously through the transmission tooth track 206. The rotation of the first transmission gear 205 drives the transmission roller shaft 203 connected to the top to rotate. There is a drive roller at the bottom of the transmission roller shaft 203. The drive rollers at the bottom of each group of transmission roller shafts 203 are driven by a track. Multiple groups of transmission roller shafts 203 drive the gas charging tank 3 to move through rotation at the same frequency and in the same direction, achieving the function of transporting the gas charging tank 3. This mechanism can also transport the compressed filling gas during gas compression through transmission.

[0071] Then, when the piston is at the outer dead center, the metal diaphragm 417 deforms under the action of the pressurized hydraulic fluid and clings to the cylinder head surface. The gas in the gas storage chamber 418 has been discharged, but there is still high-pressure residual gas due to the clearance volume. When the telescopic piston 412 in the oil cylinder moves towards the inner dead center, the oil pressure in the oil storage chamber 413 gradually decreases until it disappears, creating a pressure difference on both sides of the metal diaphragm 417. The metal diaphragm 417 begins to retract and deform under the action of the gas residual pressure and its own deformation force. The volume of the gas storage chamber 418 increases, and the air pressure begins to decrease. When the air pressure in the chamber is less than the pressure of the gas to be sucked, the suction valve 404 automatically opens, and the suction process begins. When the telescopic piston 412 continues to move towards the inner dead center, the metal diaphragm 417 continues to deform towards the oil storage chamber 413 side under the pressure difference. When the telescopic piston 412 in the oil cylinder moves to the inner dead center position, the metal diaphragm 417 deforms to the lower limit position and the suction valve 404 closes, ending the suction process. When the telescopic piston 412 starts to move towards the outer dead center, the oil pressure begins to rise, and the metal diaphragm 417 deforms towards the outer dead center. The volume of the gas storage chamber 418 gradually becomes smaller. When the gas pressure in the gas storage chamber 418 is greater than the air pressure in the exhaust pipeline, the exhaust valve 405 opens, completing the compression process and discharging the gas until the telescopic piston 412 in the oil cylinder moves to the outer dead center. When the metal diaphragm 417 clings to the cylinder head, the suction valve 404 closes, ending the exhaust process. Thus, a working cycle is completed; the output gas is transported to the gas pipeline interface 408 through the exhaust valve 405 and filled in the inflatable tank 3. The function of the opening and closing controller 406 installed in the middle of the pipeline is to open and close the pipeline, and the function of the filter 407 is to filter the compressed gas. When transporting the gas, the second transmission gear 701 is always rotating. When the telescopic screw 803 rises and the connecting plug 805 and the telescopic screw 803 engage, the inflatable tank 3 is filled with gas. At the same time, the transportation component 2 is activated, which can drive the inflatable tank 3 to move.
