Description

Technical Field

[0001] This utility model relates to a reciprocating booster pump, and more particularly to a novel booster pump that minimizes kinetic energy consumption. Background Technology

[0002] Electricity storage faces challenges due to factors such as energy efficiency, safety, lifespan, and environmental conditions. Disc reciprocating booster pumps can more efficiently convert electrical energy into air kinetic energy for storage. Currently, the best and most energy-efficient compressed air machinery on the market is the screw compressor. This machine utilizes the circular motion of the motor to maximize the use of electrical energy, which has higher mechanical kinetic energy efficiency than the linear reciprocating motion of a piston. However, the amount of air compressed per revolution of a screw compressor is relatively small; even at high speeds, its production capacity is lower than that of a disc reciprocating booster pump for the same energy efficiency.

[0003] Taking a twin-screw pump operating at an ambient temperature of 20℃ as an example, the twin-screw pump is a non-contact compression pump (each time air enters the cylinder, it needs to go through six to eight revolutions, constantly squeezing and rubbing, to complete the compression requirement). There are gaps of tens of micrometers between the screws and between the screws and the cylinder, so oil (low-temperature oil) must be injected into the cylinder (oil is injected from the air inlet, and the oil-air mixture is discharged from the air outlet) to form an oil film inside, thereby filling these gaps and preventing internal air from escaping during compression. Since the reasonable speed of a twin-screw pump is only 1000 rpm, at higher speeds, most of the energy is converted into heat energy during mechanical operation, and since it is a one-way cooling system, the temperature difference inside the cylinder is large, reaching up to 50 degrees Celsius, resulting in lower working efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a disc-shaped reciprocating booster pump that can convert kinetic energy into mechanical energy more efficiently, thereby improving work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disc-shaped reciprocating booster pump, comprising a central shaft, cylinders, and blades. The central shaft is connected to a power device via a transmission device and rotates under the action of the power device. Multiple cylinders are evenly distributed around the central shaft. An inlet check valve and an outlet check valve are provided on the side wall of each cylinder, with a gap between adjacent cylinders. The inlet check valve is connected to a gas source, and the outlet check valve is connected to a storage space for storing pressurized gas or liquid. The blades are mounted axially on the central shaft, located inside the cylinders, and rotate synchronously with the central shaft. The cylinders and blades are sealed within a mechanical housing formed by a frame and a sealing plate.

[0006] Preferably, the intake check valve and the exhaust check valve are distributed vertically on the cylinder sidewall.

[0007] Furthermore, it also includes a middle partition, which is set between the frame and the cylinder, thereby separating the intake one-way valve and the exhaust one-way valve into independent intake chambers and storage chambers.

[0008] Preferably, the transmission device includes an eccentric disk and a balance wheel; the eccentric disk is connected to the output shaft of the power device and rotates with the power device; one end of the balance wheel is connected to the eccentric rod on the eccentric disk, and the other end is connected to the central shaft, driving the central shaft to perform pendulum-like reciprocating motion.

[0009] Preferably, bearings are installed at both ends of the central shaft, which isolate the central shaft from the mechanical housing, thereby reducing the running resistance of the central shaft.

[0010] Preferably, the intake check valve is connected to the storage space via a booster pipe.

[0011] Preferably, the mechanical housing includes an upper frame, a lower frame, a head plate, and a lower sealing plate; the upper frame and the lower frame are arranged vertically around the circumference of the cylinder, and both have through holes on their side walls, which serve as inlets or outlets for gas or liquid; the head plate covers the top of the upper frame; and the lower sealing plate covers the bottom of the lower frame.

[0012] Working Principle: This booster pump is powered by an electric motor, which drives an eccentric disc to rotate. The eccentric rod on the eccentric disc drives a pendulum wheel on the central shaft to perform a pendulum-like reciprocating motion. The pendulum wheel, driven by the electric motor, causes the central shaft to perform a pendulum-like reciprocating motion. The booster pump includes a cylinder, a central shaft, and blades mounted on the central shaft. The blades reciprocate within the cylinder. During this reciprocating motion, air or liquid is forced open by the pressure difference within the cylinder due to the air pressure difference, allowing gas or liquid to enter the cylinder. At the other end of the blades, the gas or liquid is compressed by the blade movement, opening the outlet check valve and allowing air or liquid to enter the storage space. A partition is installed between the inlet and outlet check valves, completely isolating them and placing them in two independent spaces. This ensures that gas or liquid is separated only in the inlet chamber and the storage chamber.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. It can maximize the use of electrical energy for air compression, greatly improving the air energy conversion rate;

[0015] 2. It reduces transmission mechanical losses and improves energy efficiency. Attached Figure Description

[0020] It should be noted that in this embodiment, the terms "upper", "middle", "lower", etc. are used to describe the invention according to the accompanying drawings or conventional usage, and do not constitute a limitation on the invention.

[0021] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described in detail as follows: A disc-shaped reciprocating booster pump includes a booster pump body, a central shaft 5, and blades 4, as shown below. Figure 3 As shown, the central shaft 5 is connected to the power device through a transmission device and rotates under the action of the power device; the main body of the booster pump includes a cylinder 1, an intermediate partition 13 and a mechanical housing. The cylinder 1 and the intermediate partition 13 are integrally formed. There are multiple cylinders 1, which are evenly distributed around the central shaft 5. An inlet check valve 3 and an outlet check valve 2 are provided on the side wall of the cylinder, and a gap is left between adjacent cylinders; the inlet check valve 3 is connected to the air source through a through hole opened on the mechanical housing, and the outlet check valve 2 is connected to the storage chamber 14. The storage chamber 14 is used to store the pressurized gas or liquid. Of course, the outlet check valve 2 can also be connected to an external storage device through a through hole opened on the mechanical housing; the blade 4 is installed axially on the central shaft 5, located inside the cylinder 1, and rotates synchronously with the central shaft 5; the cylinder 1 and the blade 4 are sealed in the mechanical housing formed by the frame and the sealing plate.

[0022] In this embodiment, the specific structure is as follows:

[0023] The mechanical housing includes an upper frame, a lower frame, a head plate, and a lower sealing plate 15; the upper frame and the lower frame are arranged around the circumference of the cylinder 1; the head plate covers the top of the upper frame; the lower sealing plate covers the bottom of the lower frame, and an opening is made on the lower sealing plate, the opening corresponding to the gap between the cylinder, for connecting the exhaust check valve 2 and the storage chamber 14; the joints of the upper frame, the lower frame, the head plate, and the lower sealing plate are sealed with sealing material.

[0024] In this embodiment, a middle partition 13 is installed between the upper frame and the lower frame, which divides the cylinder 1 and the upper and lower frames into two spaces. As a preferred embodiment, the intake one-way valve 3 and the exhaust one-way valve 2 are opened on the side wall of the cylinder 1, that is, the intake one-way valve 3 is located in the upper space and the exhaust one-way valve 2 is located in the lower space, which divides the space where the intake one-way valve 3 and the exhaust one-way valve 2 are located into independent intake chamber 11 and storage chamber 12.

[0025] In this embodiment, the two ends of the central shaft 5 are located at the center of the head plate and the lower end plate, and bearings 6 are installed at the connection with the head plate and the lower end plate. The bearings 6 isolate the central shaft 5 from the mechanical housing, thereby reducing the running resistance of the central shaft 5.

[0026] In this embodiment, there are four cylinders 1, which are symmetrically distributed around the central axis 5. Their cross-sectional shape is fan-shaped, with openings at both the top and bottom. An opening for inserting and rotating blades 4 is opened at the end closest to the central axis 5.

[0027] In this embodiment, there are four blades 4, corresponding to the number of cylinders 1. A slot is opened in the axial direction of the cylinder to allow the blades to be inserted, so that the blades 4 can be engaged with the cylinder 1.

[0028] In this embodiment, the transmission device is installed inside the transmission box 10, and the power device is installed above the transmission box. The power device can be an electric motor, a pneumatic source, etc. In this embodiment, the power device is an electric motor 9. The transmission device includes an eccentric disk 8 and a swing wheel 7. The eccentric disk 8 is connected to the output shaft of the electric motor and rotates with the electric motor 9. One end of the swing wheel 7 is connected to the eccentric rod on the eccentric disk 8, and the other end is connected to the central shaft 5, driving the central shaft 5 to perform pendulum-like reciprocating motion.

[0029] In this embodiment, the transmission box 10, the mechanical housing, and the storage compartment 14 are arranged from top to bottom.

[0030] A pressure limiting device is added near the location of the air outlet on the storage chamber 14. When the pressure reaches the upper limit, the pressure limiting device can release the pressure and cut off the power supply to the motor at the same time to prevent the booster pump from exploding.

[0031] To achieve the high pressure requirement, a booster pipe is installed between the intake check valve 3 and the storage chamber 14 during secondary pressurization. Only one intake check valve 3 is used to draw the compressed air from the other cylinders 1 out of the storage chamber through the booster pipe. After pressurization, the compressed air is discharged from the booster pump through the corresponding exhaust check valve 2 and the installed booster pipe, so that the high-pressure air (gas to liquid) is discharged into the external storage tank or used directly.

[0032] When the booster pump operates by reciprocating between the blades and the cylinder, a diaphragm or corrugated expansion tube (not shown in the figure) can be added. Because harmful gases or liquids can corrode the booster pump, the diaphragm or corrugated expansion tube can effectively isolate these gases or liquids outside the pump body, so that they only come into contact with the diaphragm or corrugated expansion tube.

[0033] The above embodiments are merely preferred embodiments of this utility model. To reduce size and adapt to more working environments, the number of cylinders and blades is not limited to four in the above embodiments, but can also be three, depending on the actual application. Of course, the mechanical housing outside the cylinder can also be removed, and the air inlet and outlet channels can be moved from the mechanical housing to the upper and lower ends of the cylinder, with corresponding adjustments to other structures. Any extensions, modifications, and equivalent substitutions made by those skilled in the art without departing from the principle of this utility model should be included within the protection scope of this utility model.
