Description

Technical Field

[0001] The invention relates to the technical field of compressed air energy storage, in particular to a compressed air pressure-stabilizing 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, such as energy density, easy leakage, pressure fluctuation, etc., the stable supply of compressed air has become an urgent problem to be solved. In this case, the storage of compressed air becomes crucial. The existing application number is CN202210925013.4, which is a universal compressed air energy storage flexible storage tank device. The patent document discloses a method of storing compressed air using an air storage tank method, wherein a plurality of independent air bag containers are arranged inside the tank body to store compressed air, and the air bag's own elastic contraction property is utilized to stably discharge a specified amount of compressed air. Specifically: the device comprises a compressed air energy storage flexible storage tank, which comprises a steel shell, wherein a plurality of flexible air bags are arranged inside the steel shell, and a suspension component and a limit component are respectively arranged at the top and the middle of the steel shell; the flexible air bag is suspended on the upper part of the steel shell and extends to the lower part of the steel shell, the middle part of the flexible air bag is limited by the limit component, and the lower end of the flexible air bag is connected to the collecting pipe through a ventilation branch pipe; the steel shell is filled with hydraulic oil, and the flexible air bag is immersed in the hydraulic oil, which fully lubricates the outer surface of the flexible air bag and stabilizes and reinforces the inflated flexible air bag; However, when using the technical solution in the above-mentioned patent document, the elastic contraction characteristics of the flexible airbag itself are mainly relied upon to apply an extrusion pressure to the compressed air stored therein, thereby expelling the compressed air; in view of the positive correlation between the extrusion pressure and the degree of expansion of the flexible airbag, when the flexible airbag shrinks to a certain extent, it is impossible to continuously provide a constant extrusion pressure to the compressed air, thereby causing the supply pressure of the compressed air to fluctuate, interfering with the stable operation of the back-end 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 pressure-stabilizing supply tank. Summary of the invention

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings.

[0030] Embodiment 1: like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, this embodiment provides a compressed air pressure-stabilizing supply storage tank, including a tank body 11 with a plurality of legs 12 at the bottom, a push disk 21 is vertically slidably installed in the tank body 11, an I-shaped rotating drum 24 is rotatably installed in the middle of the pushing disk 21, a through-guide rod 13 is fixedly installed in the middle of the inner side of the tank body 11, the I-shaped rotating drum 24 is sleeved on the outside of the through-guide rod 13 and is connected to the through-guide rod 13 through a threaded transmission, a multi-stage telescopic guide rod is connected between the top of the pushing disk 21 and the tank body 11, and a high-torque low-speed motor 26 for driving the I-shaped rotating drum 24 to rotate is installed on the pushing disk 21.

[0031] In this embodiment, the bottom of the pushing plate 21, the inner wall of the tank body 11 and the upper side of the bottom of the tank body 11 form a compressed air storage space; a pressure sensor I is provided at the bottom of the pushing plate 21 to detect the gas pressure at the bottom of the pushing plate 21.

[0032] In order to maintain the pressure stability of the tank body 11 in the upper area of ​​the pushing plate 21, as shown in FIG. Figure 1 and Figure 2As shown, an air pressure balance pipe 14 is arranged on the top of the tank body 11, and the other end of the air pressure balance pipe 14 is connected to the external atmosphere; as the pushing disk 21 rises and falls vertically, the air is discharged from the tank body 11 to the outside or flows into the tank body 11 through the air pressure balance pipe 14, so as to maintain the pressure stability in the area above the pushing disk 21 of the tank body 11.

[0033] The air pressure balance pipe 14 is provided with an electric control valve, a gas pressure sensor and an air filter; when the gas pressure sensor on the air pressure balance pipe 14 detects compressed air leakage in the compressed air storage space, the electric control valve is closed to prevent compressed air from leaking from the air pressure balance pipe 14 and affecting the external environment of the equipment.

[0034] like Figure 7 As shown, an annular sprocket 25 is fixedly installed on the top of the I-shaped rotating drum 24, and a driving sprocket 27 is connected to the output shaft of the high-torque low-speed motor 26. The driving sprocket 27 and the annular sprocket 25 are connected through a chain 28. The power supply line of the high-torque low-speed motor 26 passes through the top of the tank body 11 and extends toward the outside of the tank body 11.

[0035] 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, and it is not bloated, which is convenient for the overall transportation and movement of the equipment; under the action of the air pressure 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 combined with the use of the air filter on the air pressure balance pipe 14, a stable dust-free environment is provided for the high-torque low-speed motor 26, thereby extending the service life of the equipment.

[0036] In order to facilitate the maintenance and inspection of the high-torque low-speed motor 26, Figure 1 As shown, a maintenance cover 16 is detachably fixedly installed on the top of the tank body 11, and the maintenance cover 16 is located directly above the high-torque low-speed motor 26; when the push plate 21 is located at the upper end of the inner side of the tank body 11, the maintenance cover 16 is opened to detect and maintain the equipment status of the high-torque low-speed motor 26, and the operation is convenient.

[0037] In this embodiment, the compressed air pressure-stabilizing supply storage tank operates independently. Specifically, two pipelines 15 with valves are provided at the bottom of the tank body 11. The two pipelines 15 are divided into 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.

[0038] The specific operating details of the compressed air pressure supply tank using this application are as follows: 1. When storing gas: First, open the valve on the air inlet pipe, close the valve on the air outlet pipe, start the air compression equipment, and inject the compressed air into the tank body 11 through the air inlet pipe; Afterwards, the high-torque low-speed motor 26 is started to control the driving sprocket 27 to rotate forward, and under the action of the chain 28, the I-shaped rotating drum 24 and the annular sprocket 25 are driven to rotate relative to the through-guide rod 13, and the threaded transmission between the I-shaped rotating drum 24 and the through-guide rod 13 is utilized to drive the push disk 21 to move vertically upward between the tank body 11 and the through-guide rod 13; according to the set position of the push disk 21, the size of the compressed air storage space is adjusted to cope with the use of demand ends of different sizes.

[0039] 2. When exhausting: First, close the valve on the air inlet pipe and open the valve on the air outlet pipe; Afterwards, the high-torque low-speed motor 26 is started, and the drive sprocket 27 is controlled to rotate in the opposite direction, driving the push disk 21 to move vertically downward between the tank body 11 and the through-guide rod 13, applying an extrusion force to the compressed air between the bottom of the push disk 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 exhaust pipe at a constant speed, thereby ensuring a stable pressure supply of compressed air.

[0040] 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.

[0041] 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.

[0042] In this embodiment, the specific structure of the multi-stage telescopic guide rod is as follows: Fig.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.

[0043] Embodiment 2: 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.

[0044] In this embodiment, the interior of the airbag 31 is a compressed air storage space. The airbag 31 is used to contain the compressed air. Compared with the solution in Example 1, the air tightness of the compressed air storage space can be further improved to cope with the stable pressure supply of compressed gas with flammable properties. Moreover, since the outer surface of the airbag 31 is not in direct contact with the pressure medium, the cleanliness of the compressed air can be effectively guaranteed.

[0045] In order to extend the service life of the airbag 31, as Figure 2 As shown, a flexible shield 131 is fixedly connected between the bottom of the I-shaped drum 24 and the bottom upper side of the through-guide rod 13, so that the outer side surface of the flexible shield 131 abuts against the inner side surface of the sealing channel integrally formed in the middle of the airbag 31, avoiding direct contact between the airbag 31 and the through-guide rod 13 to cause scratches.

[0046] Embodiment three: 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: Fig.10As shown, in this embodiment, the multi-stage telescopic guide rod includes a hollow cylinder seat 41 and a pressure medium conduit 431, and the hollow cylinder seat 41 and the pressure medium conduit 431 are connected by a plurality of guide sleeves 42 nested with each other; the hollow cylinder seat 41 is fixedly mounted on the upper side of the bottom of the pushing disk 21, the pressure medium conduit 431 passes through the top of the tank body 11 and extends toward the outside of the tank body 11, and the pressure medium conduit 431 is connected to the delivery pump through pipeline II; the pressure medium can use HG or HV or other types of hydraulic oil that can be purchased on the market.

[0047] Start the delivery pump to inject or extract a specified amount of pressure medium between the hollow cylinder seat 41, the pressure medium conduit 431 and the multiple guide sleeves 42, limit the telescopic range of the multi-stage telescopic guide rod, make the vertical movement of the push disk 21 more stable, and lock the push disk 21 at any position inside the tank body 11, providing double protection for the stable pressure supply of compressed air.

[0048] Embodiment 4: The features common to the third embodiment are not described in detail here. The differences between the third embodiment and the present embodiment are as follows: Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in this embodiment, a container for storing pressure medium is added to the push plate 21, the overall weight of the push plate 21 is adjusted, and the workload of the high-torque low-speed motor 26 is reduced. Specifically: A C-shaped bin 51 is fixedly installed on the pushing disk 21, and a flow passage 511 at the bottom of the C-shaped bin 51 is connected to the flow hole 411 at the lower end of the side of the hollow cylinder seat 41. A piston 52 is vertically slidably installed in the C-shaped bin 51, and a T-shaped seat 53 is fixedly installed on the top of the piston 52. The T-shaped seat 53 passes through the top of the C-shaped bin 51 and extends to the upper side of the C-shaped bin 51, and a tension spring 54 is fixedly installed between the T-shaped seat 53 and the upper side surface of the C-shaped bin 51.

[0049] When it is necessary to control the push disk 21 to move downward, pressure medium is injected into the pressure medium conduit 431. During this process, the pressure medium passes through the pressure medium conduit 431, multiple guide sleeves 42 and the hollow cylinder seat 41 in sequence, and finally enters the C-shaped chamber 51. During this process, the pressure medium pushes the piston 52 upward, increasing the overall weight of the push disk 21. It is used in situations where higher gas pressure requirements are required for stable pressure delivery.

[0050] When it is necessary to control the push plate 21 to move upward, 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 chamber 51 can be fully emptied, thereby reducing the overall weight of the push plate 21.

[0051] Using the above solution of this embodiment can effectively reduce the workload of the high-torque low-speed motor 26, extend the service life of the equipment, and ensure long-term continuous and stable operation of the equipment.

[0052] Embodiment five: 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 in this embodiment, multiple groups of compressed air pressure-stabilizing supply tanks are operated synchronously, and a distributed management strategy and an automated control system are combined to achieve partition control and monitoring, thereby improving the fault redundancy capability of the overall system and ensuring the long-term stable use of the equipment. Specifically: The tank bodies 11 are provided with multiple ones, and two pipelines 15 with built-in valves are provided at the bottom of each tank body 11. The two pipelines 15 are divided into an air inlet pipe and an air outlet pipe. The air inlet pipes at the bottom of the multiple tank bodies 11 are connected with the air compression equipment through independent pipelines I respectively, and the air outlet pipes at the bottom of the multiple tank bodies 11 are connected with the compressed air demand end through a multi-channel pipeline joint; the multi-channel pipeline joint can use a linear P multi-channel pipeline joint distributor or a multi-way valve distributor or a branch valve box or a multi-channel rotary joint that can be purchased on the market.
