Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and more particularly to a compressed air constant-pressure supply storage tank. Background Art

[0002] As an important energy carrier, compressed air is widely used in industrial production and daily life. However, due to some inherent problems in its production and use processes, such as high energy density, easy leakage, pressure fluctuations, etc., the stable supply of compressed air has become an urgent problem to be solved. In this case, storing compressed air becomes crucial.

[0003] There is a prior general compressed air energy storage flexible storage tank device with the application number CN202210925013.4. This patent document discloses a method of storing compressed air using a gas storage tank. Compressed air is stored by arranging multiple mutually independent airbag containers inside the tank body. Utilizing the elastic contraction characteristic of the airbag itself, a specified amount of compressed air is stably discharged. Specifically: The device includes a compressed air energy storage flexible storage tank, which includes a steel shell. Multiple flexible airbags are arranged inside the steel shell, and a suspension assembly and a limiting assembly are respectively arranged at the top and in the middle inside the steel shell. The flexible airbag is suspended at the upper part of the steel shell and extends all the way to the lower part of the steel shell. The middle part of the flexible airbag is limited by the limiting assembly, and the lower end of the flexible airbag is communicated with a ventilation branch pipe and a collecting pipe. Hydraulic oil is filled inside the steel shell, and the flexible airbag is immersed in the hydraulic oil, which fully lubricates the outer surface of the flexible airbag and plays a role in stabilizing and strengthening the inflated flexible airbag.

[0004] However, when using the technical solution in the above patent document, mainly relying on the elastic contraction characteristic of the flexible airbag itself, an extrusion force is applied to the compressed air stored inside it, so as to discharge the compressed air. In view of the positive correlation between the magnitude of the extrusion force and the expansion degree of the flexible airbag, when the flexible airbag shrinks to a certain extent, it can no longer continuously provide a constant extrusion force to the compressed air, resulting in fluctuations in the supply pressure of the compressed air and interfering with the stable operation of the subsequent equipment. Although this situation can be alleviated by releasing multiple flexible airbags one by one, this will greatly increase the number of valve devices and sealing ends, which is not conducive to the subsequent maintenance and long-term use of the equipment. Therefore, the present application provides a compressed air constant-pressure supply storage tank. Summary of the Invention

[0005] To solve the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a compressed air pressure-stabilizing supply storage tank, which can accurately control the extrusion force of the compressed air stored inside the tank body, maintain a constant discharge speed of the compressed air, ensure the pressure-stabilizing supply of the compressed air, and on this basis, can fully discharge the compressed air stored inside the tank body, thereby increasing the accommodation efficiency of the storage tank for the compressed air.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0007] A compressed air pressure-stabilizing supply storage tank is provided, including a tank body. A push plate is vertically slidably installed inside the tank body. An I-shaped rotating cylinder is rotatably installed in the middle of the push plate. A through-core guide rod is fixedly installed in the middle of the inner side of the tank body. The I-shaped rotating cylinder is sleeved outside the through-core guide rod and is in threaded transmission connection with the through-core guide rod.

A high-torque low-speed motor for driving the I-shaped rotating cylinder to rotate is installed on the push plate.

[0008] The compressed air pressure-stabilizing supply storage tank of the present application can operate independently. The specific connection method with external equipment is as follows:

The two pipelines are divided into an air inlet pipe and an air outlet pipe; the air inlet pipe is connected to an air compression device through Pipeline I, and the air outlet pipe is connected to the compressed air demand end.

[0010] The compressed air pressure-stabilizing supply storage tanks of the present application can also operate synchronously in multiple groups. The specific connection method with external equipment is as follows:

[0011] A plurality of tank bodies are provided. Two pipelines with self-contained valves are provided at the bottom of each tank body. The two pipelines are divided into an air inlet pipe and an air outlet pipe. The air inlet pipes at the bottoms of the plurality of tank bodies are respectively connected to an air compression device through independent Pipeline I, and the air outlet pipes at the bottoms of the plurality of tank bodies are connected to the compressed air demand end through a multi-way pipeline joint.

[0012] Among them, the multi-way pipeline joint can use a linear P multi-pipeline joint distributor or a multi-way valve distributor or a branch valve box or a multi-way rotary joint that can be purchased on the market.

[0013] Furthermore, a ring-shaped sprocket is fixedly installed at the top of the I-shaped rotating cylinder, and a driving sprocket is connected to the output shaft of the high-torque low-speed motor. The driving sprocket and the ring-shaped sprocket are connected by a chain.

[0014] Furthermore, a pneumatic balance pipe is provided at the top of the tank body, and a gas pressure sensor and an air filter are provided on the pneumatic balance pipe.

[0015] Furthermore, an airbag is installed between the bottom of the pushing disk and the upper side of the top of the tank body. A sealing channel for the through-core guide rod to penetrate is integrally formed in the middle of the airbag. Two air pipes are arranged at the bottom of the airbag, and the two air pipes are respectively fixedly connected with the two pipelines in an embedded manner.

[0016] Furthermore, a flexible shield is fixedly connected between the bottom of the I-shaped rotating cylinder and the upper side of the bottom of the through-core guide rod. The outer side surface of the flexible shield abuts against the inner side surface of the sealing channel in the middle of the airbag.

[0017] Furthermore, a sealing sleeve is sleeved on the outer side of the pushing disk. The outer side surface of the sealing sleeve abuts against the inner side surface of the tank body.

[0018] For the specific structure of the multi-stage telescopic guide rod used in this application, an alternative technical solution is: the multi-stage telescopic guide rod includes a hollow cylinder base and a limit post, and the hollow cylinder base and the limit post are connected by a plurality of mutually nested guide sleeves; the hollow cylinder base and the limit post are respectively fixedly installed on the upper side of the bottom of the pushing disk and the lower side of the top of the tank body.

[0019] For the specific structure of the multi-stage telescopic guide rod used in this application, another alternative technical solution is: the multi-stage telescopic guide rod includes a hollow cylinder base and a pressure medium conduit, and the hollow cylinder base and the pressure medium conduit are connected by a plurality of mutually nested guide sleeves; the hollow cylinder base is fixedly installed on the upper side of the bottom of the pushing disk, the pressure medium conduit penetrates through the top of the tank body and extends towards the outer side of the tank body, and the pressure medium conduit is communicated with the delivery pump through Pipeline II.

[0020] Furthermore, a C-shaped bin is fixedly installed on the pushing disk. The flow passage at the bottom of the C-shaped bin is communicated with the flow hole at the lower end of the side of the hollow cylinder base. A piston is vertically slidably installed in the C-shaped bin. A T-shaped seat is fixedly installed at the top of the piston. The T-shaped seat penetrates through the top of the C-shaped bin and extends towards the upper side of the C-shaped bin. A tension spring is fixedly installed between the T-shaped seat and the upper side surface of the C-shaped bin.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. For the compressed air constant pressure supply storage tank exemplified by the present invention, by controlling the downward movement of the pushing disk in the tank body, the multi-stage telescopic guide rod extends, and an extrusion force is applied to the compressed air between the bottom of the pushing disk and the upper side of the bottom of the tank body, so that the compressed air in the compressed air storage space can be discharged through the air discharge pipe at a constant speed, ensuring the constant pressure supply of compressed air; since the diameter of the pushing disk is relatively wide, on the basis of the small-distance movement of the pushing disk, a large volume of compressed air can be extruded and pushed, with high response efficiency, and the extrusion force on the compressed air stored inside the tank body can be accurately controlled.

[0023] 2. The compressed air pressure-stabilizing supply storage tank of the present invention example can fully discharge the compressed air stored inside the tank body due to the large vertical lifting and moving range of the pushing plate inside the tank body, increasing the accommodation efficiency of the storage tank for compressed air; during air storage, by adjusting the size of the compressed air storage space according to the set position of the pushing plate, it can meet the demand sides of different scales.

[0024] 3. The compressed air pressure-stabilizing supply storage tank of the present invention example has a compact internal structure and good integrity without being bulky, facilitating the overall handling and movement of the equipment because the large-torque low-speed motor is installed inside the tank body; under the action of the air pressure balance pipe, the pressure in the area between the upper side of the pushing plate and the lower side of the top of the tank body is constant, and in combination with the air filter on the air pressure balance pipe, a stable dust-free environment is provided for the large-torque low-speed motor, extending the service life of the equipment.

[0025] 4. In the compressed air pressure-stabilizing supply storage tank of the present invention example, an airbag is installed between the bottom of the pushing plate and the upper side of the top of the tank body; using the airbag to accommodate compressed air can further improve the airtightness of the compressed air storage space, meet the pressure-stabilizing supply of compressed gas with flammable characteristics, and since the outer side of the airbag does not directly contact the pressure medium, it can effectively ensure the cleanliness of the compressed air.

[0026] 5. In the compressed air pressure-stabilizing supply storage tank of the present invention example, a C-shaped bin is fixedly installed on the pushing plate, and the circulation passage at the bottom of the C-shaped bin is communicated with the circulation hole at the lower end of the side of the hollow cylinder base; injecting pressure medium into the pressure medium conduit, the pressure medium passes through the pressure medium conduit, multiple guide sleeves and the hollow cylinder base in sequence, and finally enters the C-shaped bin. During this process, the pressure medium pushes the piston upward, increasing the overall weight of the pushing plate, which is used in the case where the gas pressure requirement for pressure-stabilizing transportation is relatively high, effectively reducing the working load at the large-torque low-speed motor, extending the service life of the equipment, and ensuring the long-term continuous and stable operation of the equipment.

[0027] 6. The compressed air pressure-stabilizing supply storage tank of the present invention example can operate multiple groups synchronously, and in combination with the distributed management strategy and the automatic control system, it can achieve zonal control and monitoring, improve the fault redundancy ability of the overall system, and ensure the long-term stable use of the equipment.

[0047] Embodiment 1:

[0048] Such as Figure 1 , Figure 2 , Figure 4 and Figure 7As shown in the figure, this embodiment provides a compressed air pressure-stabilizing supply storage tank, which includes a tank body 11 with a plurality of legs 12 provided at the bottom. A push plate 21 is vertically slidably installed in the tank body 11. An I-shaped rotating cylinder 24 is rotatably installed in the middle of the push plate 21. A through-core guide rod 13 is fixedly installed in the middle inside the tank body 11. The I-shaped rotating cylinder 24 is sleeved outside the through-core guide rod 13 and is in threaded transmission connection with the through-core guide rod 13. A plurality of telescopic guide rods are connected between the top of the push plate 21 and the tank body 11. A high-torque low-speed motor 26 for driving the I-shaped rotating cylinder 24 to rotate is installed on the push plate 21.

[0049] In this embodiment, a compressed air storage space is formed by the bottom of the push plate 21, the inner wall of the tank body 11, and the upper side of the bottom of the tank body 11; a pressure sensor I is provided at the bottom of the push plate 21 for detecting the gas pressure at the bottom of the push plate 21.

[0050] In order to maintain the pressure stability in the area above the push plate 21 in the tank body 11, as Figure 1 and Figure 2 shown, a pneumatic balance pipe 14 is provided at the top of the tank body 11, and the other end of the pneumatic balance pipe 14 is connected to the external atmosphere; as the push plate 21 moves up and down vertically, air is discharged from or flows into the tank body 11 through the pneumatic balance pipe 14 to maintain the pressure stability in the area above the push plate 21 in the tank body 11.

[0051] An electric control valve, a gas pressure sensor, and an air filter are provided on the pneumatic balance pipe 14; when the gas pressure sensor on the pneumatic balance pipe 14 detects a leakage of compressed air in the compressed air storage space, the electric control valve is closed to prevent the compressed air from leaking from the pneumatic balance pipe 14 and affecting the external environment of the equipment.

[0052] As Figure 7 shown, a ring-shaped sprocket 25 is fixedly installed at the top of the I-shaped rotating cylinder 24. A driving sprocket 27 is connected to the output shaft of the high-torque low-speed motor 26. The driving sprocket 27 and the ring-shaped sprocket 25 are in transmission connection through a chain 28; the power supply wire of the high-torque low-speed motor 26 passes through the top of the tank body 11 and extends outward in the direction of the outside of the tank body 11.

[0053] Among them, since the high-torque low-speed motor 26 is installed inside the tank body 11, the internal structure of the equipment is compact, the integrity is good, it is not bulky, and it is convenient for the overall handling and movement of the equipment; under the action of the pneumatic balance pipe 14, the pressure in the area between the upper side of the push plate 21 and the lower side of the top of the tank body 11 is constant, and in combination with the air filter on the pneumatic balance pipe 14, a stable dust-free environment is provided for the high-torque low-speed motor 26, extending the service life of the equipment.

[0054] In order to facilitate the maintenance and detection of the high-torque low-speed motor 26, as Figure 1As shown, a maintenance cover 16 is detachably and fixedly installed at the top of the tank body 11, and the maintenance cover 16 is directly above the high-torque low-speed motor 26; when the pushing disc 21 is at the upper end inside the tank body 11, opening the maintenance cover 16 enables the detection and maintenance of the equipment status of the high-torque low-speed motor 26, with good operational convenience.

[0055] In this embodiment, the compressed air pressure-stabilizing supply storage tank operates independently. Specifically: two pipelines 15 with built-in valves are provided at the bottom of the tank body 11, and the two pipelines 15 are respectively an air inlet pipe and an air outlet pipe; the air inlet pipe is connected to the air compression equipment through Pipeline Ⅰ, and the air outlet pipe is connected to the compressed air demand end.

[0056] The specific operation details of using the compressed air pressure-stabilizing supply storage tank of this application are as follows:

[0057] I. When storing gas:

[0058] First, open the valve on the air inlet pipe, close the valve on the air outlet pipe, start the air compression equipment, and inject compressed air into the tank body 11 through the air inlet pipe;

[0059] After that, start the high-torque low-speed motor 26, control the driving sprocket 27 to rotate forward, and under the action of the chain 28, drive the I-shaped rotating cylinder 24 and the annular sprocket 25 to rotate relative to the through-core guide rod 13 together. Utilize the screw drive between the I-shaped rotating cylinder 24 and the through-core guide rod 13 to drive the pushing disc 21 to move vertically upward between the tank body 11 and the through-core guide rod 13; according to the set position of the pushing disc 21, adjust the size of the compressed air storage space to meet the use requirements of demand ends of different scales.

[0060] II. When exhausting gas:

[0061] First, close the valve on the air inlet pipe and open the valve on the air outlet pipe;

[0062] After that, start the high-torque low-speed motor 26, control the driving sprocket 27 to rotate reversely, drive the pushing disc 21 to move vertically downward between the tank body 11 and the through-core guide rod 13, apply an extrusion force to the compressed air between the bottom of the pushing disc 21 and the upper side of the bottom of the tank body 11, so that the compressed air in the compressed air storage space can be discharged through the air outlet pipe at a constant speed, ensuring the pressure-stabilizing supply of compressed air.

[0063] During the implementation of the above operations, the multi-stage telescopic guide rod plays a limiting role, preventing the pushing disk 21 from rotating about its own axis, so that the pushing disk 21 can move vertically stably; in addition, since the diameter of the pushing disk 21 is relatively wide, a relatively large volume of compressed air can be squeezed and pushed on the basis of the pushing disk 21 moving a small distance, thereby accurately controlling the squeezing force on the compressed air stored in the tank body 11; since the pushing disk 21 has a relatively large vertical lifting and lowering range in the tank body 11, the compressed air stored in the tank body 11 can be fully discharged, thereby increasing the storage tank's capacity for compressed air.

[0064] In order to ensure the airtightness of compressed air storage space, Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an annular edge I is integrally formed on the outer edge of the push disk 21, and an engaging edge 23 is integrally formed at the center of the push disk 21. The I-shaped rotating drum 24 is rotatably installed on the inner side of the engaging edge 23, and a sealing sleeve 22 is sleeved and installed on the outer side of the annular edge I so that the outer side surface of the sealing sleeve 22 abuts against the inner side surface of the tank body 11; the annular edge I and the engaging edge 23 are used to increase the contact area between the push disk 21 and the remaining components, and under the joint action of the sealing sleeve 22, a larger sealed isolation area is formed to ensure the airtightness of the compressed air storage space.

[0065] In this embodiment, the specific structure of the multi-stage telescopic guide rod is as follows: Figure 11 As shown, it includes a hollow cylinder seat 41 and a limiting column 432, and the hollow cylinder seat 41 and the limiting column 432 are connected by a plurality of guide sleeves 42 nested with each other; the hollow cylinder seat 41 and the limiting column 432 are respectively fixedly mounted on the bottom upper side of the pushing disk 21 and the top lower side of the tank body 11, the hollow cylinder seat 41 and the limiting column 432; the vertical movement of the pushing disk 21 in the tank body 11 is guided and limited by utilizing the mutual fitting and sliding connection of the hollow cylinder seat 41, the limiting column 432 and the plurality of guide sleeves 42.

[0066] Embodiment 2:

[0067] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, an airbag 31 is installed between the bottom of the pushing plate 21 and the top upper side of the tank body 11, and a sealing channel for the through-guide rod 13 to pass through is integrally formed in the middle of the airbag 31, and two air pipes 32 are provided at the bottom of the airbag 31, and the two air pipes 32 are respectively engaged and fixedly connected with the two pipelines 15.

[0068] In this embodiment, the interior of the airbag 31 is a compressed air storage space, which is used to accommodate compressed air. Compared with the solution in Embodiment 1, it can further improve the airtightness of the compressed air storage space, cope with the stable pressure supply of compressed gas with flammable characteristics, and since the outer side of the airbag 31 does not directly contact the pressure medium, it can effectively ensure the cleanliness of the compressed air.

[0069] To extend the service life of the airbag 31, as Figure 2 shown, a flexible shield 131 is fixedly connected between the bottom of the I-shaped rotating cylinder 24 and the upper side of the bottom of the through-core guide rod 13, so that the outer side of the flexible shield 131 abuts against the inner side of the sealing channel integrally formed in the middle of the airbag 31, avoiding direct contact between the airbag 31 and the through-core guide rod 13 and causing abrasion.

[0070] Embodiment 3:

[0071] The features identical to those in Embodiment 1 will not be elaborated here. The difference between this embodiment and Embodiment 1 lies in: as Figure 10 shown, in this embodiment, the multi-stage telescopic guide rod includes a hollow cylinder base 41 and a pressure medium conduit 431. The hollow cylinder base 41 and the pressure medium conduit 431 are connected by a plurality of nested guide sleeves 42; the hollow cylinder base 41 is fixedly installed on the upper side of the bottom of the push plate 21, the pressure medium conduit 431 penetrates through the top of the tank body 11 and extends towards the outside of the tank body 11, and the pressure medium conduit 431 is communicated with the delivery pump through Pipeline II; the pressure medium can use hydraulic oil of type HG or HV or other types that can be purchased on the market.

[0072] Start the delivery pump, inject or extract a specified amount of pressure medium between the hollow cylinder base 41, the pressure medium conduit 431 and the plurality of guide sleeves 42, limit the telescopic amplitude of the multi-stage telescopic guide rod, make the vertical movement of the push plate 21 more stable, and can lock the push plate 21 at any position inside the tank body 11, providing a double guarantee for the stable pressure supply of compressed air.

[0073] Embodiment 4:

[0074] The features identical to those in Embodiment 3 will not be elaborated here. The difference between this embodiment and Embodiment 3 lies in: as Figure 4 、 Figure 5 、 Figure 7 and Figure 8 shown, in this embodiment, a container for storing the pressure medium is added to the push plate 21 to adjust the overall weight of the push plate 21 and reduce the working load at the large torque low speed motor 26. Specifically:

[0075] A C-shaped bin 51 is fixedly installed on the pushing plate 21. A circulation passage 511 at the bottom of the C-shaped bin 51 is communicated with a circulation hole 411 at the lower end of the side of the hollow cylinder base 41. A piston 52 is vertically slidably installed in the C-shaped bin 51. A T-shaped seat 53 is fixedly installed at the top of the piston 52. The T-shaped seat 53 penetrates through the top of the C-shaped bin 51 and extends upward from the C-shaped bin 51. A tension spring 54 is fixedly installed between the T-shaped seat 53 and the upper side surface of the C-shaped bin 51.

[0076] When it is necessary to control the downward movement of the pushing plate 21, pressure medium is injected into the pressure medium conduit 431. During this process, the pressure medium sequentially passes through the pressure medium conduit 431, a plurality of guide sleeves 42 and the hollow cylinder base 41, and finally enters the C-shaped bin 51. During this process, the pressure medium pushes the piston 52 upward, increasing the overall weight of the pushing plate 21, and is used in the case where the gas pressure requirement for stable pressure transmission is relatively high.

[0077] When it is necessary to control the upward movement of the pushing plate 21, the pressure medium is extracted from the pressure medium conduit 431. During this process, under the action of the tension spring 54, the piston 52 always has a tendency to move downward, so that the pressure medium in the C-shaped bin 51 can be fully emptied, reducing the overall weight of the pushing plate 21.

[0078] Using the above solution of this embodiment can effectively reduce the working load at the large-torque low-speed motor 26, extend the service life of the equipment, and ensure the long-term continuous and stable operation of the equipment.

[0079] Embodiment Five:

[0080] The features identical to those of Embodiment One in this embodiment will not be described in detail. The difference between this embodiment and Embodiment One lies in: In this embodiment, multiple compressed air stable pressure supply storage tanks operate synchronously, and in combination with a distributed management strategy and an automatic control system, zoning control and monitoring are realized, improving the fault redundancy ability of the overall system and ensuring the long-term stable use of the equipment. Specifically:

[0081] A plurality of the tanks 11 are provided. Two pipelines 15 with self-contained valves are provided at the bottom of each tank 11. The two pipelines 15 are respectively an air inlet pipe and an air outlet pipe. The air inlet pipes at the bottoms of the plurality of tanks 11 are respectively communicated with an air compression device through independent pipelines Ⅰ. The air outlet pipes at the bottoms of the plurality of tanks 11 are communicated with a compressed air demand end through a multi-pass pipeline joint; The multi-pass pipeline joint can use a straight P multi-way pipeline joint distributor or a multi-way valve distributor or a branch valve box or a multi-pass rotary joint that can be purchased on the market.

Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the technical solution formed by mutually replacing the above features with technical features (but not limited to) having similar functions disclosed in the present application.
