Description

Technical Field

[0001] This invention relates to the field of reciprocating vertical oil-free vacuum pump technology, specifically to the inlet and outlet mechanism and control system of a reciprocating vertical oil-free vacuum pump. Background Technology

[0002] Reciprocating vertical oil-free vacuum pumps are mainly used to provide a clean vacuum environment. They work by using the reciprocating linear motion of a piston within a cylinder to draw in, compress, and expel gas. As the piston moves downwards, the pump chamber volume increases, the internal pressure decreases, the inlet valve opens, and gas is drawn in. As the piston moves upwards, the pump chamber volume decreases, the gas is compressed, and the inlet valve closes. When the gas is compressed to pressure exceeding atmospheric pressure, the exhaust valve opens, and the compressed gas is expelled from the pump. This cycle repeats continuously to achieve continuous vacuum pumping. These pumps are typically classified as low to medium vacuum pumps, with an ultimate vacuum level generally in the range of 1 to 100 Pa, and cannot achieve high or ultra-high vacuum.

[0003] Reciprocating vertical oil-free vacuum pumps are divided into double-acting pumps and single-acting pumps. In order to improve the pumping efficiency, operators usually use double-acting pumps instead of single-acting pumps. In a single-acting pump, the piston moves upward to pump air and moves downward to release air. One reciprocating motion only performs one intake and release. In contrast, the piston of a double-acting pump pumps both pump air and release air simultaneously when it moves upward and downward. One reciprocating motion can perform two intake and release operations, resulting in higher pumping efficiency.

[0004] Although double-acting pumps improve pumping efficiency, they also significantly increase the energy consumption of their drive motor. In double-acting pumps, since the gas is compressed in each stroke, the average resistance torque and peak torque required by the motor shaft are much higher than those in single-acting pumps. The motor must use more energy to rotate, which greatly increases the energy consumption of the entire reciprocating vertical oil-free vacuum pump motor.

[0005] Therefore, it is necessary to design an inlet and outlet mechanism for a reciprocating vertical oil-free vacuum pump that saves energy consumption of the double-acting pump motor. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the piston is driven by the motor to move up and down reciprocally, thereby driving the reciprocating vertical oil-free vacuum pump to pump and release gas. The gas enters the interior of the first gas guide tube through the first gas guide tube. Driven by the gas, the rotating plate slides and rotates around the rotating cylinder. Since the rotating shaft is fixedly connected to the rotating cylinder, the rotational torque is directly transmitted to the rotating shaft, providing it with a continuous auxiliary driving torque to assist the main drive motor in driving the rotating shaft. This significantly reduces the shaft kinetic energy required by the motor, achieving the effect of energy saving. Furthermore, the gas after energy conversion in the first gas guide tube is transmitted to the gas groove and then sprayed out from each jet nozzle in sequence, blowing away the dust on the surface of the piston rod that is moving up and down in a linear motion. This effectively prevents contaminants from being carried into the interior of the precision sealing ring with the piston rod, thus preventing the sealing ring from wearing, scratching, or failing.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-7 The present invention provides a technical solution: a reciprocating vertical oil-free vacuum pump intake and exhaust mechanism, including a base 1, a transmission assembly 8 on the upper side of the base 1, an intake and exhaust assembly 9 for performing air extraction and exhaust movements on the upper side of the transmission assembly 8, the transmission assembly 8 including a transmission box 83 fixedly connected to the upper side of the base 1, heat dissipation grooves 832 on both sides of the transmission box 83, a dust collection box 81 slidably connected inside the transmission box 83, a force assist assembly 82 on the upper side of the dust collection box 81, a rotating shaft 834 rotatably connected inside the transmission box 83, a second connecting rod 833 fixedly connected to one end of the rotating shaft 834, a first connecting rod 831 hinged to the other end of the second connecting rod 833, and an air chamber box 91 fixedly connected to the upper side of the dust collection box 81.

[0020] The following is a supplementary explanation based on the above structure: the heat dissipation slot 832 is used to dissipate the heat generated by the movement between internal mechanical parts, and the dust collection box 81 is used to store dust falling from above.

[0021] A motor 6 is fixedly connected to the upper side of the base 1. A support platform 2 is provided on one side of the motor 6 and the support platform 2 is fixedly connected to the base 1.

[0022] An air outlet box 92 and an air intake box 93 are fixedly connected to both sides of the air chamber box 91, respectively. An air intake pipe 934 is fixedly connected to one side of the air intake box 93, and an air outlet pipe 924 is fixedly connected to one side of the air outlet box 92. A piston 911 is slidably connected inside the air chamber box 91. A piston rod 912 is fixedly connected to the lower side of the piston 911. The piston rod 912 is fixedly connected to the first connecting rod 831 and slidably connected to the air chamber box 91. A dust removal component 84 is provided on the outer side of the piston rod 912.

[0023] The following is a supplementary explanation based on the above structure: the gas outlet box 92 is used to store the released gas, and the gas inlet box 93 is used to store the inlet gas.

[0024] The rotation of the output end of motor 6 is used to drive the connecting shaft 5 to rotate. The rotation of the connecting shaft 5 drives the first turntable 3 to rotate, which in turn drives the second turntable 7 to rotate via the belt. At this time, the rotating shaft 834 is indirectly driven to rotate.

[0025] When the rotating shaft 834 rotates, it drives the second connecting rod 833 to rotate around the rotating shaft 834, thereby driving the first connecting rod 831 to swing. The piston rod 912 is driven to move up and down reciprocally, which in turn drives the piston 911 to slide up and down reciprocally inside the air chamber box 91.

[0026] One side of the air chamber box 91 is provided with a second air intake groove 916 and a first air intake groove 914 from top to bottom, and the other side of the air chamber box 91 is provided with a second air outlet groove 915 and a first air outlet groove 913 from top to bottom. The second air intake groove 916 is provided with a third sliding rod 932 inside. One end of the third sliding rod 932 is fixedly connected to a first air intake valve 931 and the other end is fixedly connected to a third limiting plate 933. The third sliding rod 932 is slidably connected to the air intake box 93.

[0027] The first air intake groove 914 is provided with a fourth sliding rod 936. One end of the fourth sliding rod 936 is fixedly connected to a second air intake valve 937 and the other end is fixedly connected to a fourth limiting plate 935. The fourth sliding rod 936 is slidably connected to the air intake box 93. The first air intake valve 931 and the second air intake valve 937 are both located inside the air chamber box 91.

[0028] The second air outlet groove 915 is provided with a first sliding rod 922. One end of the first sliding rod 922 is fixedly connected to a first air outlet valve 921 and the other end is fixedly connected to a first limiting plate 923. The first sliding rod 922 is slidably connected to the air outlet box 92.

[0029] The first air outlet groove 913 is provided with a second sliding rod 926. One end of the second sliding rod 926 is fixedly connected to a second air outlet valve 927 and the other end is fixedly connected to a second limiting plate 925. The second sliding rod 926 is slidably connected to the air outlet box 92. The second air outlet valve 927 and the first air outlet valve 921 are both located inside the air outlet box 92.

[0030] The following is a supplementary explanation of the above structure: Piston 911 slides up and down reciprocally inside the air chamber box 91. When piston 911 moves upward, the volume below piston 911 increases, the pressure drops rapidly, and a partial vacuum is formed. At this time, the air pressure inside the suction box 93 is relatively high. This pressure difference pushes the second intake valve 937 to move to the right, thereby opening the first intake groove 914 to draw in air, drawing the gas inside the suction box 93 into the area below piston 911, i.e., inside the air chamber box 91. The lower air chamber is in a low-pressure intake state, and its pressure is lower than the pressure inside the outlet box 92. Therefore, the higher air pressure inside the outlet box 92 will drive the second outlet... Valve 927 moves to the left, thereby closing the first air outlet groove 913. The volume above piston 911 decreases, and the pressure rises sharply. The high pressure in the upper air chamber is much greater than the pressure in the intake box 93. Therefore, this high pressure will push the first intake valve 931 to move to the left, thereby closing the second intake groove 916. The gas above piston 911 is compressed, and the pressure rises. This high pressure makes the pressure in the upper air chamber higher than the pressure in the air outlet box 92. This pressure difference will push the first air outlet valve 921 to move to the right, thereby opening the second air outlet groove 915 and delivering the gas inside the air chamber box 91, that is, the gas above piston 911, to the inside of the air outlet box 92.

[0031] When piston 911 moves downward, the volume below piston 911 decreases, and the pressure increases. This pressure causes the second intake valve 937 to move to the left, thereby closing the first intake slot 914. After the pressure in the lower air chamber increases, it becomes higher than the pressure in the outlet box 92. This pressure difference pushes the second outlet valve 927 to move to the right, transporting the gas inside the air chamber box 91, i.e., the gas below piston 911, into the outlet box 92. The volume above piston 911 increases, and the pressure decreases, forming... A partial vacuum is created. The pressure difference between the higher pressure inside the suction box 93 and the lower pressure in the upper air chamber pushes the first intake valve 931 to the right, thereby opening the second suction slot 916. This draws the gas inside the suction box 93 into the space above the piston 911, i.e., into the air chamber box 91. When the piston 911 moves downward, the upper air chamber is in a low-pressure suction state, and its pressure is lower than the pressure inside the outlet box 92. The gas pressure inside the outlet box 92 will move the first outlet valve 921 to the left, thereby closing the second outlet slot 915.

[0032] The force-assisted component 82 includes a first air guide cylinder 822 disposed inside the transmission box 83. A first positioning post 823 is fixedly connected to the outside of the first air guide cylinder 822. The other end of the first positioning post 823 is fixedly connected to the transmission box 83. An air outlet 825 and an air inlet 826 are respectively provided inside the first air guide cylinder 822. A rotating cylinder 828 is rotatably connected inside the first air guide cylinder 822. The rotating cylinder 828 is fixedly connected to a rotating shaft 834. Six rotating plates 827 are evenly fixedly connected to the outside of the rotating cylinder 828. The rotating plates 827 are slidably connected to the inside of the first air guide cylinder 822. A first air guide pipe 821 is fixedly connected inside the air outlet 825. The other end of the first air guide pipe 821 is fixedly connected to an air outlet pipe 924.

[0033] The following is a supplementary explanation based on the above structure: the gas with a certain pressure discharged from the exhaust pipe 924 is guided to the sealed cavity of the first air guide cylinder 822 via the first air guide pipe 821. The high-pressure gas acts on the sliding rotating plate 827 inside the air guide cylinder, and the gas pressure is converted into a driving force on the rotating plate 827, pushing it to slide along a specific trajectory. Since the rotating plate 827 and the rotating cylinder 828 are rigidly connected by a mechanical structure, the linear sliding of the rotating plate 827 is then converted into the rotational motion of the rotating cylinder 828 around its axis. Since the rotating shaft 834 is fixedly connected to the rotating cylinder 828, the rotational torque is directly transmitted to the rotating shaft 834, providing it with a continuous auxiliary driving torque. This design essentially constitutes an energy recovery system, which effectively captures and converts the fluid kinetic energy and pressure potential energy of the discharged gas into beneficial mechanical kinetic energy to assist the main drive motor 6 in driving the rotating shaft 834. This significantly reduces the shaft kinetic energy required by the motor 6, achieving the purpose of saving energy consumption and improving the overall energy efficiency of the system.

[0034] The air inlet 826 is fixedly connected to a second air guide pipe 824. The dust removal assembly 84 includes an air inlet pipe 843 fixedly connected to the other end of the second air guide pipe 824. The other end of the air inlet pipe 843 is fixedly connected to a second air guide cylinder 842. The outer side of the second air guide cylinder 842 is fixedly connected to a second positioning post 841, and the other end of the second positioning post 841 is fixedly connected to the transmission box 83. The interior of the second air guide cylinder 842 is provided with an air groove 845. Several jet nozzles 844 are evenly fixedly connected to the inner ring of the air groove 845. The jet nozzles 844 are installed obliquely downward.

[0035] After energy conversion within the first air guide tube 822, the gas is orderly discharged from its dedicated outlet 825 during the system's operating cycle. It is then transported via the second air guide tube 824 and finally injected into an annularly distributed air groove 845 structure through the air inlet tube 843. This air groove 845 serves as a gas distribution channel, uniformly guiding the gas to a series of precisely arranged jet nozzles 844. These jet nozzles 844 are directed towards the surface of the piston rod 912, which is undergoing reciprocating linear motion, forming a series of high-speed, focused airflow jets. This design constitutes a non-contact active cleaning system. Its core function is to use continuous directional airflow impact to promptly and effectively blow away any dust particles, debris, and other contaminants that may be adsorbed on the surface of the piston rod 912 during each stroke. This aims to intervene at the source by forming an air curtain barrier, blocking the path of contaminants carried into the precision sealing ring by the piston rod 912, thereby fundamentally preventing wear, scratches, or sealing failure of the sealing ring caused by foreign object intrusion.

[0036] Motor 6 drives piston 911 to move up and down reciprocally, thereby driving reciprocating vertical oil-free vacuum pump to pump and release gas. Gas enters the interior of first air guide cylinder 822 through first air guide pipe 821. Driven by the gas, rotating plate 827 slides, which in turn drives rotating plate 827 to rotate around rotating cylinder 828. Since rotating shaft 834 is fixedly connected to rotating cylinder 828, rotational torque is directly transmitted to rotating shaft 834, providing it with continuous auxiliary driving torque. This assists main drive motor 6 in driving rotating shaft 834, thereby significantly reducing the shaft kinetic energy required by motor 6 and achieving energy saving effect. After energy conversion in first air guide cylinder 822, gas is transferred to air groove 845 and then ejected from each jet nozzle 844 in sequence, blowing away dust from the surface of piston rod 912, which is moving up and down in a linear motion. This effectively prevents contaminants from being carried into the precision sealing ring with the piston rod 912, thus preventing wear, scratches, or sealing failure of the sealing ring.

[0037] A reciprocating vertical oil-free vacuum pump control system, based on the aforementioned reciprocating vertical oil-free vacuum pump inlet and outlet mechanism, includes the following steps: S1: Motor 6 starts to control the rotation of the first turntable 3, which indirectly drives the rotation of the second turntable 7, thereby driving the rotating shaft 834 to rotate.

[0038] S2: The rotation of the shaft 834 drives the second connecting rod 833 to rotate, causing the first connecting rod 831 to swing, thereby driving the piston rod 912 to move up and down, and in turn driving the piston 911 to move up and down, so that the intake and exhaust assembly 9 can perform the intake and exhaust movement.

[0039] S21: Piston 911 slides up and down along the inside of the air chamber box 91. When piston 911 moves upward, the volume below piston 911 increases, the pressure drops rapidly, and a partial vacuum is formed. At this time, the air pressure in the suction box 93 is relatively high. This pressure difference pushes the second intake valve 937 to move to the right, thereby opening the first suction groove 914 to draw in air, drawing the gas inside the suction box 93 into the area below piston 911, that is, inside the air chamber box 91. The lower air chamber is in a low-pressure suction state, and its pressure is lower than the pressure in the outlet box 92. Therefore, the higher air pressure in the outlet box 92 will drive the second outlet valve 927. The piston moves to the left, thus closing the first air outlet 913. The volume above the piston 911 decreases, and the pressure rises sharply. The high pressure in the upper air chamber is much greater than the pressure in the intake box 93. Therefore, this high pressure will push the first intake valve 931 to move to the left, thereby closing the second intake box 916. The gas above the piston 911 is compressed, and the pressure rises. This high pressure makes the pressure in the upper air chamber higher than the pressure in the air outlet box 92. This pressure difference will push the first air outlet valve 921 to move to the right, thereby opening the second air outlet 915 and transporting the gas inside the air chamber box 91, that is, the gas above the piston 911, to the inside of the air outlet box 92.

[0040] S22: When piston 911 moves downward, the volume below piston 911 decreases and the pressure increases. This pressure causes the second intake valve 937 to move to the left, thereby closing the first intake slot 914. After the pressure in the lower air chamber increases, its pressure becomes higher than the pressure in the outlet box 92. This pressure difference pushes the second outlet valve 927 to move to the right, transporting the gas inside the air chamber box 91, i.e., the gas below piston 911, into the outlet box 92. The volume above piston 911 increases and the pressure decreases. This creates a partial vacuum. The pressure difference between the higher pressure inside the suction box 93 and the lower pressure in the upper air chamber pushes the first intake valve 931 to the right, thereby opening the second suction slot 916. This draws the gas inside the suction box 93 into the space above the piston 911, i.e., into the air chamber box 91. When the piston 911 moves downward, the upper air chamber is in a low-pressure suction state, and its pressure is lower than the pressure inside the outlet box 92. The gas pressure inside the outlet box 92 will move the first outlet valve 921 to the left, thereby closing the second outlet slot 915.

[0041] S3: The released gas flows out from the gas outlet pipe 924, passes through the first gas guide pipe 821 and flows into the interior of the first gas guide cylinder 822. The airflow pushes the rotating plate 827, indirectly driving the rotating cylinder 828 to rotate, thereby assisting the rotating shaft 834 to rotate and compensating for the load on the motor 6.

[0042] S31: The gas with a certain pressure discharged from the exhaust pipe 924 is guided into the sealed cavity of the first air guide tube 822 through the first air guide tube 821. The high-pressure gas acts on the sliding rotating plate 827 inside the air guide tube, and the gas pressure is converted into a driving force on the rotating plate 827, pushing it to slide along a specific trajectory. Since the rotating plate 827 and the rotating cylinder 828 are rigidly connected by a mechanical structure, the linear sliding of the rotating plate 827 is then converted into the rotational motion of the rotating cylinder 828 around its axis. Since the rotating shaft 834 is fixedly connected to the rotating cylinder 828, the rotational torque is directly transmitted to the rotating shaft 834, providing it with a continuous auxiliary driving torque.

[0043] S4: The gas flows inside the first air guide tube 822, and finally flows into the air groove 845 through the second air guide tube 824 and the air inlet tube 843. The gas nozzle 844 blows away the dust on the surface of the reciprocating rotating shaft 834.

[0044] S41: The gas that has completed energy conversion in the first air guide tube 822 will be orderly discharged from its dedicated air outlet 825 during the system operation cycle, and then transported through the second air guide tube 824, and finally injected into the interior of an annularly distributed air groove 845 structure through the air inlet tube 843. The air groove 845 serves as a gas distribution channel, which can uniformly guide the gas to a series of precisely arranged jet heads 844.
