Description

Technical Field

[0001] The present invention relates to the technical field of gas compressors, and in particular to a gas compressor with high sealing performance. Background Art

[0002] With the development of industry, the requirements for the purity of compressed air are constantly increasing, especially in the medical, food, pharmaceutical and other industries, which have extremely high requirements for the purity of compressed air. Traditional oil-lubricated compressors cannot meet the needs of these industries due to the use of lubricating oil. The emergence of oil-free compressors is precisely to meet the needs of these industries for high-purity compressed air. An oil-free compressor is a compressor that does not use lubricating oil during the compression process. Its main feature is that no oil molecules are mixed into the compressed air during the compression process, thereby providing cleaner compressed air. This type of compressor is suitable for industries with high requirements for air purity, such as medical, food, pharmaceutical, and electronic manufacturing. However, because oil-free compressors abandon lubricating oil, they have high requirements for the working environment and cannot effectively filter dust in the air. At the same time, the components wear out greatly during use, which not only causes high working noise, but also seriously affects the stability and service life of the equipment. In addition, due to the lack of oil lubrication, the temperature of the oil-free compressor cannot be effectively controlled, resulting in the oil-free compressor being unable to be used continuously for a long time, seriously affecting the working efficiency of the oil-free compressor. Summary of the Invention

The eccentric shaft is rotatably installed inside the cavity, and a sliding sleeve is rotatably installed on the side wall of the eccentric shaft. A connecting rod is rotatably installed on the side wall of the sliding sleeve. The connecting rod and the bottom of the plunger are rotatably connected. The vent plug is fixedly installed inside the cavity and is located at the bottom of the compression chamber.

[0005] In the above-mentioned high-sealing gas compressor, a second annular groove is provided on the side wall of the plunger, and the second annular groove is located between the outer side of the sliding chamber and the inner wall of the compression chamber. A first annular groove is provided on the side wall of the bottom of the sliding chamber, and the first annular groove is located on the outer side of the sliding piston. A number of evenly distributed through holes are provided between the first annular groove and the second annular groove, and the bottom of the second annular groove and the bottom of the through holes are both inclined downward.

[0006] In the above-mentioned high-sealing gas compressor, a water storage chamber is provided inside the sliding plug, a rubber sheet is provided on the top of the water storage chamber, and a plurality of evenly distributed water holes are provided on the side wall of the water storage chamber, and the water holes penetrate the sliding plug to the interior of the sliding chamber.

[0007] In the above-mentioned high-sealing gas compressor, a water absorption chamber is integrally formed at the bottom of the sliding plug, the water absorption chamber and the water storage chamber are connected to each other, and a piston is integrally formed on the side wall of the plunger, and the piston is slidably installed inside the water absorption chamber.

[0008] In the above-mentioned high-sealing gas compressor, a water tank is provided on the outside of the cavity, and a water pipe 1 is fixedly connected to the side wall of the water tank. A spiral water pipe is movably installed inside the cavity, and the two ends of the spiral water pipe are respectively fixedly connected to the water suction cavity and water pipe 1. The fixed connection between the spiral water pipe and the water suction cavity is located on the side wall of the piston.

[0009] In the above-mentioned high-sealing gas compressor, the connecting rod passes through the vent plug and is movably inserted into the interior of the vent plug. A sealing cover is provided between the vent plug and the connecting rod. A vent hole is provided on the side wall of the vent plug, and the vent hole is tangent to the inner wall of the cavity.

[0010] In the above-mentioned high-sealing gas compressor, a wind hood is fixedly installed on the side wall of the cavity, an impeller is fixedly installed on the side wall of the eccentric shaft, the impeller is located between the cavity and the wind hood, a drive motor is provided on the outside of the cavity, and the output shaft of the drive motor passes through the side wall of the cavity and is fixedly connected to the eccentric shaft.

[0011] In the above-mentioned high-sealing gas compressor, a plurality of evenly distributed exhaust holes 2 are provided on the side wall of the cavity, the exhaust holes 2 are tangent to the inner wall of the cavity, the exhaust holes 2 correspond to the compression chamber, and the side wall of the cavity cover is provided with exhaust holes 1.

[0012] Compared with the existing technology, the advantages of the present invention are: 1. The present invention cooperates with the impeller and the cavity. During the process of the impeller rotating following the eccentric shaft, the impeller introduces air into the interior of the cavity and drives the air to rotate, so that the air cools the cavity. The exhaust hole 2 and the air rotate in the same direction, so that the air is discharged from the interior of the cavity through the exhaust hole 2 and cools the compression chamber. Through the rotation of the impeller, the air enters from the side wall of the cavity and rotates after entering, thereby improving the heat dissipation effect of the cavity and the compression chamber during operation and avoiding the problem that the cavity and the compression chamber are too hot and cannot work for a long time.

[0013] 2. The present invention cooperates with the second exhaust hole and the vent hole. During the process of the impeller driving the air inside the cavity to rotate, the dust rotates closely against the inner wall of the cavity and is discharged through the second exhaust hole. The directions of rotation of the vent hole and the air are opposite, so that when air is replenished between the plunger and the vent plug, the vent hole draws dust-free air into the space between the plunger and the vent plug for inflation. By designing the second exhaust hole and the vent hole in opposite directions, the impeller removes dust from the air during the process of guiding the air to rotate, thereby improving the purity of the compressed air inside the compression chamber.

[0014] 3. The present invention cooperates between the plunger and the sliding plug. When the plunger moves downward, the sliding plug moves to the top of the sliding cavity. At this time, the plunger and the sliding plug are separated. The air flows through the gap between the plunger and the sliding plug, passes through the annular groove 1, the through hole and the annular groove 2 in sequence, and then moves to the space between the plunger and the cavity cover for inflation. The air is guided by the plunger and the sliding plug, so that the air cools the plunger, thereby increasing the service life of the plunger and improving the heat dissipation effect of the plunger.

[0015] 4. The present invention cooperates between the water storage chamber, the first ring groove and the second ring groove. When the plunger moves upward, the plunger and the sliding plug are tightly fitted, so that the pressure inside the compression chamber is increased. At this time, the rubber sheet squeezes the water storage chamber, and the cold water inside the water storage chamber flows to the first ring groove through the water hole, and forms a water ring above the first ring groove and the second ring groove. The water ring above the first ring groove improves the sealing between the sliding plug and the plunger through the water ring formed above the first ring groove and the second ring groove. The water ring above the second ring groove lubricates the plunger, reduces the friction between the plunger and the compression chamber and the noise during the operation of the plunger, and at the same time improves the service life of the plunger. In the process of the sliding plug sliding upward, the rubber sheet returns to its position and absorbs the water ring above the first ring groove. The water ring above the second ring groove is evenly distributed on the inner wall of the compression chamber, so that in the process of air cooling the plunger, the volatilization of residual water stains is accelerated, and the heat dissipation effect of the plunger and the compression chamber is further improved.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0020] Reference Figure 1 - Figure 10As shown, a highly sealed gas compressor includes a chamber 1. A plurality of evenly distributed compression chambers 141 are fixedly mounted on the sidewall of the chamber 1. A chamber cover 142 is fixedly mounted on the top of each compression chamber 141. A compression assembly is movably mounted inside the compression chamber 141. The compression assembly includes a plunger 23 and a sliding plug 24. The plunger 23 is slidably mounted inside the compression chamber 141. A sliding cavity 235 is integrally formed on the top of the plunger 23. The sliding plug 24 is slidably mounted inside the sliding cavity 235. An inflation component is movably installed inside the cavity 1, and the inflation component includes an eccentric shaft 121 and a vent plug 22. The eccentric shaft 121 is rotatably installed inside the cavity 1, and a sliding sleeve 21 is rotatably installed on the side wall of the eccentric shaft 121. A connecting rod 211 is rotatably installed on the side wall of the sliding sleeve 21. The connecting rod 211 and the bottom of the plunger 23 are rotatably connected. The vent plug 22 is fixedly installed inside the cavity 1, and the vent plug 22 is located at the bottom of the compression chamber 141.

[0021] like Figure 1 、 Figure 4 and Figure 10 As shown, a wind hood 11 is fixedly installed on the side wall of the cavity 1, and an impeller 122 is fixedly installed on the side wall of the eccentric shaft 121. The impeller 122 is located between the cavity 1 and the wind hood 11. A drive motor 12 is provided on the outside of the cavity 1. The output shaft of the drive motor 12 passes through the side wall of the cavity 1 and is fixedly connected to the eccentric shaft 121.

[0022] like Figure 1 、 Figure 2 and Figure 10 As shown, the side wall of the cavity 1 is provided with a plurality of evenly distributed exhaust holes 144 , the exhaust holes 144 and the inner wall of the cavity 1 are tangent, the exhaust holes 144 and the compression cavity 141 correspond, and the side wall of the cavity cover 142 is provided with exhaust holes 143 .

[0023] Among them, after starting the drive motor 12, the drive motor 12 drives the eccentric shaft 121 to rotate, and the impeller 122 rotates following the eccentric shaft 121, so that the impeller 122 introduces the outside air into the interior of the cavity 1 through the wind cover 11, and drives the air to rotate, so that the air cools the cavity 1, and the exhaust hole 144 and the air rotate in the same direction, so that the air is discharged from the interior of the cavity 1 through the exhaust hole 144. When the air moves to the outside of the cavity 1, the air contacts the side wall of the compression chamber 141, so that the air cools the compression chamber 141. Through the rotation of the impeller 122, the air enters from the side wall of the cavity 1 and rotates after entering, thereby improving the heat dissipation effect of the cavity 1 and the compression chamber 141 during operation, and avoiding the problem that the temperature of the cavity 1 and the compression chamber 141 is too high and cannot work for a long time.

[0024] like Figure 5-Figure 8As shown, the side wall of the plunger 23 is provided with a second annular groove 232, which is located between the outer side of the sliding chamber 235 and the inner wall of the compression chamber 141. The side wall of the bottom of the sliding chamber 235 is provided with a first annular groove 231, which is located on the outer side of the sliding plug 24. A number of evenly distributed through holes 233 are provided between the first annular groove 231 and the second annular groove 232, and the bottom of the second annular groove 232 and the bottom of the through holes 233 are both inclined downward.

[0025] When the eccentric shaft 121 rotates, the sleeve 21 rotates along with the eccentric shaft 121, so that the sleeve 21 drives the plunger 23 to move up and down reciprocatingly through the connecting rod 211. When the plunger 23 moves upward, the slide 24 moves to the bottom of the sliding chamber 235. At this time, the plunger 23 and the slide 24 fit tightly together and squeeze the air inside the compression chamber 141. The squeezed air is discharged through the exhaust hole 143. When the plunger 23 moves downward, the slide 24 moves to the top of the sliding chamber 235. At this time, the plunger 23 and the sliding plug 24 are separated, and the air between the cavity 1 and the plunger 23 flows through the gap between the plunger 23 and the sliding plug 24, passes through the annular groove 1 231, the through hole 233 and the annular groove 2 232 in sequence, and then moves to the space between the plunger 23 and the cavity cover 142 for inflation. The air is guided by the plunger 23 and the sliding plug 24, so that the air cools the plunger 23, increases the service life of the plunger 23, and improves the heat dissipation effect of the plunger 23, thereby avoiding the problem that the plunger 23 is too hot and cannot work for a long time.

[0026] like Figure 5-Figure 9 As shown, a water storage chamber 241 is provided inside the sliding plug 24 , a rubber sheet 244 is provided on the top of the water storage chamber 241 , and a plurality of evenly distributed water holes 242 are provided on the side wall of the water storage chamber 241 , which penetrate the sliding plug 24 to the interior of the sliding chamber 235 .

[0027] When the plunger 23 moves upward, the pressure inside the compression chamber 141 increases, causing the rubber sheet 244 to squeeze the water storage chamber 241, and the cold water inside the water storage chamber 241 flows to the annular groove 1 231 through the water hole 242. When a water ring is formed between the annular groove 1 231 and the sliding plug 24, the cold water flows to the annular groove 2 232 through the through hole 233, so that a water ring is also formed between the annular groove 232 and the compression chamber 141. The cold water inside the water storage chamber 241 is discharged, so that a water ring is formed above the annular groove 1 231 and the annular groove 2 232. The water ring above the annular groove 1 231 improves the sealing between the sliding plug 24 and the plunger 23, and the annular groove 232 is The square water ring lubricates the plunger 23, reduces the friction between the plunger 23 and the compression chamber 141 and the noise during the operation of the plunger 23, and at the same time increases the service life of the plunger 23. When the plunger 23 moves downward, the sliding plug 24 slides upward, the rubber sheet 244 returns to its position and absorbs the water ring above the ring groove 1 231. The water ring above the ring groove 232 is evenly distributed on the inner wall of the compression chamber 141. When the air passes through the gap between the plunger 23 and the sliding plug 24 and flows through the ring groove 1 231, the through hole 233 and the ring groove 2 232 in turn, the volatilization of residual water stains is accelerated, further improving the heat dissipation effect of the plunger 23 and the compression chamber 141.

[0028] like Figure 1 、 Figure 4 and Figure 6-Figure 9 As shown, a water absorption chamber 243 is integrally formed at the bottom of the sliding plug 24, and the water absorption chamber 243 and the water storage chamber 241 are communicated with each other. A piston 234 is integrally formed on the side wall of the plunger 23, and the piston 234 is slidably installed inside the water absorption chamber 243. A water tank 13 is provided on the outside of the cavity 1, and a water pipe 131 is fixedly connected to the side wall of the water tank 13. A spiral water pipe 132 is movably installed inside the cavity 1, and both ends of the spiral water pipe 132 are respectively fixedly connected to the water absorption chamber 243 and the water pipe 131. The fixed connection between the spiral water pipe 132 and the water absorption chamber 243 is located on the side wall of the piston 234.

[0029] When the plunger 23 moves downward, the piston 234 slides downward, and the sliding plug 24 moves upward to the inside of the sliding chamber 235. At this time, the water storage chamber 241 and the water suction chamber 243 are in a negative pressure state. When the piston 234 slides downward, the spiral water pipe 132 and the water suction chamber 243 are connected to each other, so that the water suction chamber 243 draws cold water from the inside of the water tank 13 through the spiral water pipe 132 and the water pipe 131. When the plunger 23 moves upward, the sliding plug 24 moves downward to the inner side of the annular groove 1 231, the piston 234 moves upward, the spiral water pipe 132 and the water suction chamber 243 are separated from each other, and the water storage chamber 241 and the water suction chamber 243 are in a positive pressure state. The relative sliding of the plunger 23 and the sliding plug 24 allows the water storage chamber 241 to be continuously replenished with water. At the same time, the changes in the internal pressures of the water storage chamber 241 and the water suction chamber 243 improve the stability of the cold water discharge.

[0030] like Figure 2 、 Figure 3 and Figure 6 As shown, the connecting rod 211 passes through the vent plug 22 and is movably inserted into the interior of the vent plug 22. A sealing cover 222 is provided between the vent plug 22 and the connecting rod 211. A vent hole 221 is opened on the side wall of the vent plug 22, and the vent hole 221 is tangent to the inner wall of the cavity 1.

[0031] Among them, in the process of the impeller 122 driving the air inside the cavity 1 to rotate, the air discharges dust through the centrifugal force generated by the rotation, so that the dust rotates closely against the inner wall of the cavity 1 and is discharged through the exhaust hole 144. The direction of rotation of the vent hole 221 is opposite to that of the air, so that in the process of the plunger 23 moving upward, air is replenished between the plunger 23 and the vent plug 22, and the vent hole 221 draws dust-free air between the plunger 23 and the vent plug 22 for inflation. By designing the exhaust hole 144 and the vent hole 221 in opposite directions, the impeller 122 removes dust from the air in the process of guiding the air to rotate, thereby improving the purity of the compressed air inside the compression chamber 141.

[0032] The specific working principle and method of use of the present invention are explained in detail below: After starting the drive motor 12, the eccentric shaft 121 rotates, and the sleeve 21 and the impeller 122 rotate along with the eccentric shaft 121. The impeller 122 introduces air into the interior of the cavity 1 and drives the air to rotate, so that the air cools the cavity 1 and is discharged from the interior of the cavity 1 through the exhaust hole 144, so that the air cools the compression chamber 141. The rotation of the impeller 122 allows the air to enter from the side wall of the cavity 1 and rotate after entering, thereby improving the heat dissipation effect of the cavity 1 and the compression chamber 141 during operation and avoiding the problem that the temperature of the cavity 1 and the compression chamber 141 is too high and cannot work for a long time. The sleeve 21 drives the plunger 23 to The reciprocating up and down movement, when the plunger 23 moves upward, the sliding plug 24 moves to the bottom of the sliding chamber 235. At this time, the plunger 23 and the sliding plug 24 are tightly fitted together and squeeze the air inside the compression chamber 141, so that the pressure inside the compression chamber 141 is increased. At this time, the rubber sheet 244 squeezes the water storage chamber 241, and the cold water inside the water storage chamber 241 flows to the annular groove 1 231 through the water hole 242, and forms a water ring above the annular groove 1 231 and the annular groove 2 232. The water ring above the annular groove 1 231 improves the sealing between the sliding plug 24 and the plunger 23, and the water ring above the annular groove 232 lubricates the plunger 23, reduces the friction between the plunger 23 and the compression chamber 141 and the noise during the working process of the plunger 23, and at the same time improves the service life of the plunger 23. The air squeezed inside the compression chamber 141 is discharged through the exhaust hole 143. When the plunger 23 moves downward, the sliding plug 24 moves to the top of the sliding chamber 235. At this time, the plunger 23 and the sliding plug 24 are separated. The air flows through the gap between the plunger 23 and the sliding plug 24, passes through the ring groove 1 231, the through hole 233 and the ring groove 2 232 in turn, and then moves to the space between the plunger 23 and the chamber cover 142 for inflation. The air is guided by the plunger 23 and the sliding plug 24, so that the air cools the plunger 23, increases the service life of the plunger 23, and improves the heat dissipation effect of the plunger 23. In the process of the sliding plug 24 sliding upward, the rubber sheet 244 returns to its position and absorbs the water ring above the ring groove 1 231. The water ring above the ring groove 232 is evenly distributed in the compression chamber 141. The inner wall of the piston 23 is used to accelerate the volatilization of residual water stains during the air cooling process of the plunger 23, further improving the heat dissipation effect of the piston 23 and the compression chamber 141. In the process of the impeller 122 driving the air inside the cavity 1 to rotate, the dust rotates close to the inner wall of the cavity 1 and is discharged through the exhaust hole 144. The direction of rotation of the vent hole 221 is opposite to that of the air, so that when air is replenished between the plunger 23 and the vent plug 22, the vent hole 221 draws dust-free air between the plunger 23 and the vent plug 22 for inflation. The design of the opposite directions of the exhaust hole 144 and the vent hole 221 allows the impeller 122 to remove dust from the air during the process of guiding the air to rotate, thereby improving the purity of the compressed air inside the compression chamber 141.

[0033] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0034] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
