Detection Device Applied to Large-Size Air Compressors

Abstract

The present invention relates to the technical field of air compressor detection, specifically a detection device applied to large-sized air compressors, including a detection frame. Inside the detection frame, there is an air guiding component. The air guiding component includes an air guiding cylinder fixedly installed on the left side of the detection frame. One end of the air guiding cylinder located inside the detection frame is penetrated with a twisting round opening. A conical spray elbow is rotatably installed around the opening of the twisting round opening, and the channel diameter of the conical spray elbow gradually decreases outward. By setting the diameter of the conical spray elbow to gradually decrease, the flow rate of air inside the conical spray elbow continuously accelerates. At the same time, due to the gradual decrease in the diameter of the conical spray elbow, the temperature of the air gradually decreases when flowing inside the conical spray elbow. With the increase in the flow rate of the air, the dust and impurities mixed in the air will be accelerated together, so that the contact speed between the dust and impurities and the adhesive tape is greater, and the impact effect is more obvious, so that they can be better adhered to the surface of the adhesive tape and can be better observed.

Description

Technical Field

[0001] The present invention relates to the technical field of air compressor detection, and specifically to a detection device applied to large-sized air compressors. Background Art

[0002] According to the detection device applied to large-sized air compressors disclosed in the authorized announcement number of the Chinese patent: CN117871789B, by driving the fan to simultaneously drive the turbine impeller inside the connecting pipe to rotate, the circulated extraction of the detected oil can be synchronized, making the sampling result more comprehensive. Moreover, the power supply requirement of the overall detection device is small, and it can be freely moved for detection without being restricted by whether there is additional power supply at the site, with a wider application range;

[0003] However, the above-mentioned detection device applied to large-sized air compressors still has deficiencies during use. For example, in this device, a filter element is used to absorb dust and impurities. Therefore, after detection, the filter element needs to be disassembled to observe the collection situation of dust and impurities. And some dust and impurities are adsorbed inside the filter holes of the filter element, making it not easy to directly observe with the naked eye, which affects the judgment of the detection personnel. Summary of the Invention

[0004] For this reason, the present invention provides a detection device applied to large-sized air compressors to solve the above problems.

[0005] The present invention provides the following technical solution: A detection device applied to large-sized air compressors, including a detection frame, and a gas guiding component is arranged inside the detection frame;

[0006] The gas guiding component includes a gas guiding cylinder fixedly installed on the left side surface of the detection frame. The gas guiding cylinder extends into the detection frame. One end of the gas guiding cylinder inside the detection frame is provided with a torsion round opening. A conical spray elbow is rotatably installed around the opening of the torsion round opening. The channel diameter of the conical spray elbow gradually decreases outward. A stirring shaft is rotatably installed in the middle of one end of the gas guiding cylinder close to the conical spray elbow. The stirring shaft extends into the gas guiding cylinder.

And the torsion rod is located above the linkage shaft rod. At one end of the torsion rod located inside the detection frame, there is an intermittent swing wheel fixedly installed. On the outer wall of the intermittent swing wheel, there are a plurality of U - shaped grooves distributed at equal angles. The specification of the U - shaped grooves is adapted to the rocker pin.

[0010] As a preferred solution of the present invention, at one end of the torsion rod far from the intermittent swing wheel, there is a driving pulley fixedly installed. At the front part of the upper one of the two winding rollers, there is a driven pulley fixedly installed. A power belt is sleeved between the driving pulley and the driven pulley.

[0011] As a preferred solution of the present invention, at both the front and rear ends of the lower one of the two winding rollers, there are disturbance components fixedly installed. The disturbance components include damping discs fixedly installed at the ends of the winding rollers. Inside the damping discs, there are a plurality of circular grooves distributed at equal angles. Inside each circular groove, there is a damping ball slidably installed.

[0012] As a preferred solution of the present invention, on the outer wall of the damping disc, there are a plurality of air pressure holes distributed at equal angles. The positions of the air pressure holes correspond to the positions of the circular grooves one by one. And the inside of the air pressure holes is connected to the inside of the circular grooves.

[0013] As a preferred embodiment of the present invention, a detection component is fixedly provided on the right wall of the detection frame. The detection component includes a pressure detector fixedly installed on the right wall of the detection frame. The pressure detector is located between the upper and lower winding rollers. A U-shaped fixing frame is fixedly installed at the detection end of the pressure detector. Both ends of the U-shaped fixing frame are commonly connected to a fixed square frame. A plurality of rollers are rotatably installed inside the fixed square frame at equal distances up and down. The outer wall of the roller is in contact with the surface of the winding roller.

[0014] As a preferred embodiment of the present invention, an observation port is penetrated and opened at the top of the detection frame. The observation port is located at the top of the adhesive tape, and a dust-proof glass is fixedly embedded inside the observation port.

[0015] As a preferred embodiment of the present invention, two replacement ports are penetrated and opened in the right part of the detection frame, and are distributed up and down. The positions of the two replacement ports correspond to the positions of the two winding rollers. A sealing plate is detachably connected to the periphery of the openings of the two replacement ports through a buckle.

[0016] As a preferred embodiment of the present invention, two flow guiding vanes are fixedly installed on the left wall of the detection frame, and are distributed up and down. The two flow guiding vanes are respectively located at the top and bottom of the air guiding cylinder. The front parts of the two flow guiding vanes are fixedly connected to the front wall of the detection frame, and the rear parts of the two flow guiding vanes are fixedly connected to the rear wall of the detection frame. A plurality of air release ports are penetrated and opened at the front and rear parts of the detection frame. The air release ports are located between the upper and lower flow guiding vanes, and dust-proof nets are fixedly embedded inside the air release ports.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, the air output from the output pipeline of the air compressor enters the inside of the air guiding cylinder, and then enters the inside of the conical spray elbow through the twisted round opening. Then the air is sprayed out at a high speed from the small end of the conical spray elbow, directly blowing on the surface of the adhesive tape. The dust and impurities in the air also directly impact on the adhesive surface of the adhesive tape along with the blowing action of the air, and are firmly adhered by the adhesive on the adhesive surface of the adhesive tape, so as to adhere to the surface of the adhesive tape. And because the diameter of the conical spray elbow gradually decreases, the flow rate of the air in the conical spray elbow continuously accelerates. At the same time, because the diameter of the conical spray elbow gradually decreases, the temperature of the air gradually decreases when flowing inside the conical spray elbow. The increase in the flow rate of the air will accelerate the dust and impurities mixed in the air together, so that the contact speed between the dust and impurities and the adhesive tape is greater, and the impact effect is more obvious, so that it can be better adhered to the surface of the adhesive tape and can be better observed.

[0019] 2. During the flow of compressed air inside the air guide cylinder in the present invention, it will agitate the turbine blades to rotate. The rotation of the turbine blades drives the driving gear to rotate through the stirring shaft. The rotation of the driving gear drives the driven shaft to rotate through the driven gear. The rotation of the driven shaft drives the eccentric block and the eccentric pin to rotate together. The rotation of the eccentric pin generates left and right thrust forces on the inner wall of the dial groove, causing the dial bar to drive the connecting column and the conical injection elbow to rotate reciprocally left and right along the connection with the air guide cylinder, so that the conical injection elbow does not concentrate on injecting dust impurities at a certain place of the adhesive tape, enabling more adhesive areas of the adhesive tape to be effectively utilized and ensuring the utilization rate of the adhesive tape.

[0020] 3. In the present invention, the winding roller rotates, thereby driving the two damping disks connected thereto to rotate. The rotation of the damping disks drives the multiple circular grooves located inside them to rotate together, resulting in the continuous change of the angles of the multiple circular grooves. Since the damping balls always slide downward along the inner wall of the circular grooves under the action of gravity, that is, during the rotation of the damping disks, the center of gravity of the damping disks is at a position below the center of the circle. Therefore, a damping effect will be generated during the rotation of the damping disks, causing the winding roller connected to the damping disks not to rotate easily, so that the adhesive tape between the upper and lower winding rollers is straightened and no accumulation phenomenon will occur.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-10 , the technical solutions provided by the present invention specifically include the following embodiments:

The air guiding cylinder 201 extends into the interior of the detection frame 1. One end of the air guiding cylinder 201 located inside the detection frame 1 is penetrated and provided with a twisting round opening 202. A conical spraying elbow 203 is rotatably installed around the opening periphery of the twisting round opening 202. The channel diameter of the conical spraying elbow 203 gradually decreases outward. In the middle of one end of the air guiding cylinder 201 close to the conical spraying elbow 203, a stirring shaft 204 is rotatably installed. The stirring shaft 204 extends into the interior of the air guiding cylinder 201 movably. A turbine blade 205 is fixedly installed at one end of the stirring shaft 204 located inside the air guiding cylinder 201. A driving gear 206 is fixedly installed at one end of the stirring shaft 204 far from the turbine blade 205. A driven gear 207 is engaged with the top of the driving gear 206. A driven shaft 208 is fixedly installed on the inner wall of the driven gear 207. The driven shaft 208 is rotatably installed on the upper part of one side surface of the air guiding cylinder 201 close to the conical spraying elbow 203. An eccentric block 209 is fixedly installed at one end of the driven shaft 208 far from the air guiding cylinder 201. An eccentric pin 2010 is fixedly installed at one end of the eccentric block 209 far from the driven shaft 208. Two connecting columns 2011 are fixedly installed on the outer wall of the conical spraying elbow 203 close to the eccentric block 209. A strip 2012 is jointly connected to the ends of the two connecting columns 2011 far from the conical spraying elbow 203. A slot 2013 is penetrated on one side surface of the strip 2012 close to the eccentric block 209. The eccentric pin 2010 is slidably located inside the slot 2013;

[0037] A dust adhering component is arranged inside the detection frame 1. The dust adhering component includes two winding rollers 301 rotatably installed between the front wall and the rear wall of the detection frame 1. The two winding rollers 301 are distributed vertically. An adhesive tape 302 is wound around the outer circumference of the lower winding roller 301. The releasing end of the adhesive tape 302 is fixedly connected to the outer wall of the upper winding roller 301. The adhesive tape 302 is located on the right part of the conical spraying elbow 203;

[0038] A detection component is fixedly arranged on the right wall of the detection frame 1. The detection component includes a pressure detector 601 fixedly installed on the right wall of the detection frame 1. The pressure detector 601 is located between the upper and lower winding rollers 301. A U-shaped fixing frame 602 is fixedly installed at the detection end of the pressure detector 601. The two ends of the U-shaped fixing frame 602 are jointly connected to a fixing square frame 603. A plurality of rollers 604 are rotatably installed in the fixing square frame 603 at equal intervals vertically. The outer wall of the roller 604 is in contact with the surface of the winding roller 301;

[0039] Specifically in this embodiment, after fixedly connecting the air output end of the air compressor to be detected with the input end of the air guide cylinder 201, start the air compressor to allow the compressed air to enter the interior of the air guide cylinder 201 through the air output pipeline of the air compressor. Subsequently, it enters the interior of the conical injection elbow 203 through the twisted round opening 202. Then, the air is ejected at high speed from the small end of the conical injection elbow 203 and directly blows on the surface of the adhesive tape 302. The dust and impurities in the air also directly impact the adhesive surface of the adhesive tape 302 along with the blowing action of the air and are firmly adhered by the adhesive on the adhesive surface of the adhesive tape 302, thus adhering to the surface of the adhesive tape 302. And because the diameter of the conical injection elbow 203 gradually decreases, the flow rate of the air in the conical injection elbow 203 continuously accelerates. At the same time, because the diameter of the conical injection elbow 203 gradually decreases, the temperature of the air gradually decreases when flowing inside the conical injection elbow 203. The increase in the flow rate of the air will accelerate the dust and impurities mixed in the air together, so that the contact speed between the dust and impurities and the adhesive tape 302 is greater and the impact effect is more obvious, so that it is better adhered to the surface of the adhesive tape 302. During the impact of the air flow output by the conical injection elbow 203 on the surface of the adhesive tape 302, the adhesive tape 302 collapses in the direction close to the roller 604 under the action of the air flow impact, thus pushing the roller 604 and the fixed square frame 603 together with the fixed square frame 603 to move in the direction close to the pressure detector 601. The detection end of the pressure detector 601 is pressed, so as to perform pressure detection and judge whether the pressure of the air compressor is qualified;

[0040] Meanwhile, during the flow of the compressed air inside the air guide cylinder 201, it will stir the turbine blade 205 to rotate. The rotation of the turbine blade 205 drives the driving gear 206 to rotate through the stirring shaft 204. The rotation of the driving gear 206 drives the driven shaft 208 to rotate through the driven gear 207. The rotation of the driven shaft 208 drives the eccentric block 209 and the eccentric pin 2010 to rotate together. The rotation of the eccentric pin 2010 generates a left-right thrust on the inner wall of the dial groove 2013, resulting in the dial bar 2012 driving the connecting column 2011 and the conical injection elbow 203 to rotate left and right along the connection with the air guide cylinder 201, so that the conical injection elbow 203 does not concentrate on spraying dust and impurities on a certain part of the adhesive tape 302, and more adhesive areas of the adhesive tape 302 are effectively utilized, ensuring the utilization rate of the adhesive tape 302.

[0041] Embodiment 2:

[0042] Inside the detection frame 1, there is a step-by-step linkage component. The step-by-step linkage component includes a twisting seat 401 fixedly installed on the left wall of the detection frame 1. Inside the twisting seat 401, a linkage shaft rod 402 is rotatably installed. The linkage shaft rod 402 is vertically distributed with respect to the driven shaft 208. And at one end of the linkage shaft rod 402 close to the driven shaft 208, a driven bevel gear 403 is fixedly installed. On the outer wall of the driven shaft 208, a driving bevel gear 404 is fixedly installed. The driving bevel gear 404 meshes with the driven bevel gear 403. The end of the linkage shaft rod 402 away from the driven bevel gear 403 movably penetrates the front surface of the detection frame 1 and is rotatably connected to the front wall of the detection frame 1;

[0043] On the outer wall of the linkage shaft rod 402, a rocker arm 405 is fixedly installed. At one end of the front surface of the rocker arm 405 away from the linkage shaft rod 402, a rocker pin 406 is fixedly installed. Inside the front part of the detection frame 1, a twisting rod 407 is rotatably installed. The twisting rod 407 extends into the detection frame 1 movably. And the twisting rod 407 is located above the linkage shaft rod 402. At one end of the twisting rod 407 located inside the detection frame 1, an intermittent swing wheel 408 is fixedly installed. On the outer wall of the intermittent swing wheel 408, a plurality of U-shaped grooves 409 are arranged at equal angles. The specification of the U-shaped groove 409 is adapted to the rocker pin 406;

[0044] At one end of the twisting rod 407 away from the intermittent swing wheel 408, a driving pulley 4010 is fixedly installed. On the front part of one of the winding rollers 301 located above, a driven pulley 4011 is fixedly installed. A power belt 4012 is jointly sleeved between the driving pulley 4010 and the driven pulley 4011;

[0045] A viewing port 101 is penetrated through the top of the detection frame 1. The viewing port 101 is located above the adhesive tape 302. And inside the viewing port 101, a dust-proof glass 102 is fixedly embedded;

[0046] Specifically, in this embodiment, during the rotation of the driven shaft 208, the driving bevel gear 404 connected thereto is also driven to rotate. The rotation of the driving bevel gear 404 drives the linkage shaft 402 to rotate in a circle around the torsion seat 401 through the driven bevel gear 403. The rotation of the linkage shaft 402 drives the rocker arm 405 together with the rocker pin 406 to rotate, so that the rocker pin 406 sequentially moves a plurality of U-shaped grooves 409, thereby pushing the intermittent swing wheel 408 to intermittently rotate together with the torsion rod 407. The intermittent swing wheel 408 intermittently rotates and drives the driving pulley 4010 to intermittently rotate together through the torsion rod 407. The driving pulley 4010 intermittently rotates and drives the driven pulley 4011 to intermittently rotate through the power belt 4012. The driven pulley 401 The intermittent rotation drives the winding roller 301 connected thereto to rotate together, so that the adhesive tape 302 on the outer periphery of the winding roller 301 at the bottom is intermittently rolled up a short section, and the upper section of the adhesive tape 302 with dust impurities adhered thereto is rolled up to the outer periphery of the winding roller 301 at the top, so as to ensure that the adhesive tape 302 at the right end of the conical jet elbow 203 always has good adhesion, so as to better absorb dust impurities, and the upwardly rolled adhesive tape 302 drives the adhered dust impurities to roll upward when passing through the bottom position of the observation port 101, and the inspector can observe the adhesion of dust impurities on the surface of the adhesive tape 302 through the dustproof glass 102, so as to judge the filtering effect of the air filter of the air compressor.

[0047] Embodiment three:

[0048] The front and rear ends of a winding roller 301 located at the bottom are fixedly installed with disturbance components, and the disturbance component includes a damping plate 501 fixedly installed at the end of the winding roller 301, and a plurality of circular grooves 502 distributed at equal angles are opened inside the damping plate 501, and damping balls 503 are slidably installed inside the circular grooves 502;

[0049] The outer wall of the damping plate 501 is provided with a plurality of air pressure holes 504 distributed at equal angles, the positions of the air pressure holes 504 correspond to the positions of the circular grooves 502 one by one, and the interior of the air pressure holes 504 is connected to the interior of the circular grooves 502;

[0050] Specifically in this embodiment, when an upper winding roller 301 rotates to wind up the adhesive tape 302 wound around the outer circumference of the lower winding roller 301 upward, the rotation will drive the lower winding roller 301 to rotate, and further drive the two damping discs 501 connected thereto to rotate. The rotation of the damping discs 501 drives the multiple circular grooves 502 located inside them to rotate together, resulting in continuous changes in the angles of the multiple circular grooves 502. Due to the action of gravity, the damping balls 503 always slide downward along the inner walls of the circular grooves 502. That is to say, during the rotation of the damping discs 501, the centers of gravity of the damping discs 501 are located below their centers. Therefore, a damping effect will be generated during the rotation of the damping discs 501, causing the winding roller 301 connected to the damping discs 501 not to rotate easily, so that the adhesive tape 302 between the upper and lower winding rollers 301 is straightened and no accumulation phenomenon will occur.

[0051] Further, two replacement openings 103 distributed vertically are formed through the right part of the detection frame 1. The positions of the two replacement openings 103 correspond to the positions of the two winding rollers 301. The peripheries of the openings of the two replacement openings 103 are detachably connected with sealing plates 104 through buckles. After the sealing plates 104 are opened, the adhesive tape 302 can be replaced through the replacement openings 103. After taking out the used adhesive tape 302 and installing the new adhesive tape 302 on the upper and lower winding rollers 301, the replacement openings 103 are sealed again by using the sealing plates 104, and at the same time, the sealing plates 104 are fixed on the peripheries of the replacement openings 103 by using the buckles.

[0052] Further, two flow guiding pieces 106 distributed vertically are fixedly installed on the left wall of the detection frame 1. The two flow guiding pieces 106 are respectively located at the top and bottom of the air guiding cylinder 201. The front parts of the two flow guiding pieces 106 are fixedly connected to the front wall of the detection frame 1, and the rear parts of the two flow guiding pieces 106 are fixedly connected to the rear wall of the detection frame 1. A plurality of air release openings 105 are formed through the front and rear parts of the detection frame 1. The air release openings 105 are located between the upper and lower flow guiding pieces 106, and dust-proof nets are fixedly embedded in the interiors of the air release openings 105. By arranging the upper and lower flow guiding pieces 106, the air discharged into the interior of the detection frame 1 can be guided forward and backward, so that the air can be smoothly discharged through the plurality of air release openings 105 formed in the front part and the rear part of the detection frame 1.

[0053] When the detection device for large-sized air compressors of this solution is working, after fixedly connecting the air output end of the air compressor to be detected to the input end of the air guide cylinder 201, start the air compressor so that the compressed air enters the interior of the air guide cylinder 201 through the air output pipeline of the air compressor, and then enters the interior of the conical spray elbow 203 through the twisted round opening 202. Subsequently, the air is ejected at high speed from the small end of the conical spray elbow 203 and directly blows on the surface of the adhesive tape 302. The dust and impurities in the air also directly impact on the adhesive surface of the adhesive tape 302 along with the blowing action of the air, and are firmly adhered by the adhesive on the adhesive surface of the adhesive tape 302, thus adhering to the surface of the adhesive tape 302. And because the diameter of the conical spray elbow 203 gradually decreases, the flow rate of the air in the conical spray elbow 203 continuously accelerates. At the same time, because the diameter of the conical spray elbow 203 gradually decreases, the temperature of the air gradually decreases when flowing inside the conical spray elbow 203. The increase in the flow rate of the air will accelerate the dust and impurities mixed in the air together, so that the contact speed between the dust and impurities and the adhesive tape 302 is greater, and the impact effect is more obvious, so that it can be better adhered to the surface of the adhesive tape 302. During the period when the airflow output from the conical spray elbow 203 impacts the surface of the adhesive tape 302, the adhesive tape 302 collapses towards the direction close to the roller 604 under the action of the airflow impact, thus pushing the roller 604 and the fixed square frame 603 together with the fixed square frame 603 to move towards the direction close to the pressure detector 601. The detection end of the pressure detector 601 is pressed, so as to conduct pressure detection and judge whether the pressure of the air compressor is qualified;

[0054] Meanwhile, during the flow of the compressed air inside the air guide cylinder 201, it will stir the turbine blade 205 to rotate. The rotation of the turbine blade 205 drives the driving gear 206 to rotate through the stirring shaft 204. The rotation of the driving gear 206 drives the driven shaft 208 to rotate through the driven gear 207. The rotation of the driven shaft 208 drives the eccentric block 209 together with the eccentric pin 2010 to rotate. The rotation of the eccentric pin 2010 generates a left-right thrust on the inner wall of the dial groove 2013, resulting in the dial bar 2012 driving the connecting column 2011 together with the conical spray elbow 203 to rotate left and right along the connection with the air guide cylinder 201, so that the conical spray elbow 203 does not concentrate on spraying dust and impurities on a certain part of the adhesive tape 302, and more adhesive areas of the adhesive tape 302 are effectively utilized, ensuring the utilization rate of the adhesive tape 302;

[0055] When the driven shaft 208 rotates, it also drives the driving bevel gear 404 connected thereto to rotate. The driving bevel gear 404 rotates and drives the linkage shaft 402 to rotate around the torsion seat 401 through the driven bevel gear 403. The linkage shaft 402 rotates and drives the rocker arm 405 and the rocker pin 406 to rotate, so that the rocker pin 406 sequentially moves a plurality of U-shaped grooves 409, thereby pushing the intermittent swing wheel 408 to rotate intermittently together with the torsion rod 407. The intermittent swing wheel 408 intermittently rotates and drives the driving pulley 4010 to rotate intermittently through the torsion rod 407. The driving pulley 4010 intermittently rotates and drives the driven pulley 4011 to rotate intermittently through the power belt 4012. The driven pulley 4011 intermittently rotates. The rotation of the adhesive tape 302 drives the connected winding roller 301 to rotate together, so that the adhesive tape 302 on the periphery of the winding roller 301 at the bottom is intermittently rolled up a short section, and the upper section of the adhesive tape 302 with dust and impurities is rolled up to the periphery of the winding roller 301 at the top, to ensure that the adhesive tape 302 at the right end of the conical jet elbow 203 always has good adhesion, so as to better absorb dust and impurities. When the upwardly rolled adhesive tape 302 drives the adhered dust and impurities to roll upward and pass through the bottom position of the observation port 101, the inspector can observe the adhesion of dust and impurities on the surface of the adhesive tape 302 through the dustproof glass 102, thereby judging the filtering effect of the air filter of the air compressor.
