Description

Technical Field

[0001] This utility model relates to the field of gas storage tank technology, and in particular to a gas storage tank with an automatic pressure relief function. Background Technology

[0002] As the service life of the multi-functional overhead crane increases, the daily operation of the overhead crane's air compressor, including shell breaking, grabbing, and soot blowing, all require compressed air produced by the air compressor. The compressed air is stored in an air tank, which has strong pressure resistance.

[0003] However, a lot of water droplets and oily residue will condense in the existing gas storage tanks and adhere to the inner wall of the tanks. If they are not drained, they may corrode the gas storage tanks. In fact, if this water is supplied to downstream equipment, it may damage the equipment. Therefore, the wastewater in the gas storage tanks needs to be discharged in a timely manner. Utility Model Content

[0004] This utility model discloses a gas storage tank with an automatic pressure relief function, which aims to solve the technical problem of existing gas storage tanks having condensation of water and oil on the inner wall, leading to corrosion of the gas storage tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas storage tank with automatic pressure relief function includes a gas storage tank body, characterized in that it further includes:

[0007] The vibration mechanism is provided in two sets and symmetrically distributed on the top of the gas storage tank body. Each set of vibration mechanism consists of a fixed frame, a hinged arm and a vibrating hammer. The fixed frame is fixedly connected to the top of the gas storage tank body. One end of the hinged arm is hinged to the fixed frame and the other end is fixedly connected to the vibrating hammer. A rubber pad is fixedly connected to the lower end of the vibrating hammer.

[0008] The drive assembly consists of a fixed base, a drive motor, a driving pulley, a driven pulley, and a conveyor belt. The fixed base is fixedly connected to the top of the gas tank body. The drive motor is fixed to the fixed base, and its output shaft is coaxially fixedly connected to the driving pulley. The driven pulley is rotatably connected to a fixed plate fixedly connected to the top of the gas tank body via a transmission shaft. An eccentric wheel is also coaxially and eccentrically fixedly connected to the transmission shaft. A drive ring that cooperates with the eccentric wheel to drive the movement of the articulated arm is fixedly connected to the lower end of the articulated arm.

[0009] Furthermore, an elastic element is connected between the fixed frame and the hinged arm. The elastic element includes an elastic tube, with its two ends in the longitudinal direction respectively hinged to the fixed frame and the hinged arm, and a spring is sleeved on the outside of the elastic tube.

[0010] Furthermore, the bottom of the gas storage tank body is provided with a liquid outlet, and a drain pipe is inserted into the liquid outlet.

[0011] Furthermore, a discharge switch valve is provided on the discharge pipe.

[0012] Furthermore, pressure detection sensors are fixedly connected to both inner walls of the gas storage tank body.

[0013] Furthermore, a pressure relief hole is provided on one side of the gas storage tank body, and an automatic pressure relief device is connected to the outside of the pressure relief hole. The automatic pressure relief device is fixedly connected to the gas storage tank body through a fixing ring.

[0014] Furthermore, the automatic pressure relief device includes a buffer housing and a pressure relief pipe. The buffer housing is connected to the pressure relief hole at the upper end of the gas storage tank body. One end of the pressure relief pipe is connected to the inside of the buffer housing, and the other end is connected to the outside. A pressure relief valve is installed on the pressure relief pipe.

[0015] Furthermore, a vacuum pump is fixedly connected to the top of the gas storage tank body, and the vacuum pump is connected to the interior of the gas storage tank body through a pipe.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By synchronously driving the vibration mechanism through the drive component, the gas tank body is struck to clean the oil and water droplets adhering to the inner wall of the gas tank body, avoiding the problem of corrosion of the inner wall caused by the long-term adhesion of oil and water droplets. At the same time, it can effectively improve the cleaning efficiency of the gas tank and reduce manual intervention and cleaning time.

[0018] 2. The vibration mechanism and drive assembly adopt an eccentric wheel + drive ring combination drive form, which can realize the reciprocating striking action of the vibratory hammer on the gas storage tank body. Moreover, the rubber pad at the lower end of the vibratory hammer can reduce the instantaneous impact force, reduce mechanical impact damage to the structure and components, extend the service life of the equipment, and reduce noise impact.

[0019] 3. An elastic tube and spring are installed between the articulated arm and the fixed frame. When the eccentric wheel drives the vibratory hammer to lift, it compresses the spring and elastic tube, converting some of the mechanical energy into the potential energy of the elastic tube and spring for storage. When the eccentric wheel rotates and releases the force, the potential energy of the spring is converted into kinetic energy and released, driving the articulated arm to move. This ensures that the vibratory hammer can always obtain sufficient rebound force for the next strike without relying entirely on gravity or additional power, thus achieving stable periodic vibration. Moreover, the elastic tube itself has certain damping and buffering characteristics, which play a role in shock absorption and limiting the movement of the articulated arm during the energy storage and release process of the spring, preventing the articulated arm from swinging excessively due to inertia or causing direct impact on the fixed frame. By absorbing and releasing energy through the deformation of the elastic element, this component effectively smooths the motion curve of the vibration mechanism. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] This utility model discloses a gas storage tank with an automatic pressure relief function, primarily applicable to existing devices. However, existing gas storage tanks tend to accumulate a lot of water and oil, which adheres to the inner wall of the tank. If this water is not completely drained, it can corrode the tank. Furthermore, if this water is supplied to downstream equipment, it may damage the equipment. Therefore, there are scenarios where the wastewater in the gas storage tank needs to be discharged promptly.

[0028] Reference Figures 1-5A gas storage tank with automatic pressure relief function includes a gas storage tank body 1, a vacuum pump 2 on the gas storage tank body 1, and an air inlet (not shown in the figure) on the upper left side. The air outlet of the vacuum pump 2 is connected to the air inlet of the gas storage tank body 1, and the vacuum pump 2 can pressurize the gas storage tank body 1. A drain pipe 25 is connected to the lower end of the gas storage tank body 1, and a drain switch valve 24 is provided on the drain pipe 25 for discharging waste liquid. Moreover, a set of vibration mechanisms and a drive component for driving the vibration mechanism are provided on the left and right sides of the top of the gas storage tank body 1, and the drive component is connected to both sets of vibration mechanisms. The drive component synchronously drives the two sets of vibration mechanisms to vibrate the gas storage tank body 1.

[0029] Specifically, each vibration mechanism consists of a fixed frame 15, a hinged arm 18, and a vibrating hammer 19. The fixed frame 15 is fixedly connected to the upper part of the gas storage tank body 1. One end of the hinged arm 18 is fixedly connected to the vibrating hammer 19 along its length, and the other end is hingedly connected to the fixed frame 15. A first hinge seat 14 is fixedly connected above the fixed frame 15. A second hinge seat 17 is fixedly connected to the upper middle part of the hinged arm 18. An elastic element is connected between the first hinge seat 14 and the second hinge seat 17. The elastic element includes an elastic tube 16, which is made of flexible rubber or elastic material. Both ends of the elastic tube 16 along its length are connected to the first hinge seat 14 and the second hinge seat 17, respectively. A spring 13 is coaxially sleeved on the outer side. Both ends of the spring 13 along its length are also connected to the first hinge seat 14 and the second hinge seat 17. A rubber pad 20 is fixedly connected to the lower end of the vibrating hammer 19.

[0030] The drive assembly consists of a fixed base 10, a drive motor 9, and a transmission assembly connecting the drive motor 9 and the vibration mechanism. The fixed base 10 is fixedly connected to the upper center of the gas storage tank body 1. The housing of the drive motor 9 is fixedly connected to the fixed base 10, and the output shaft of the drive motor 9 is coaxially fixedly connected to a rotating shaft 8 via a coupling. Each rotating shaft 8 is connected to one of the two vibration mechanisms via a set of transmission assemblies. Specifically, the transmission assembly includes a drive pulley 11, a driven pulley 5, a conveyor belt 7, a drive shaft 6, and an eccentric wheel 12. The drive pulley 11 is coaxially fixedly connected to the rotating shaft 8. A fixed plate 22 is fixedly connected to the upper end face near the hinge arm 18. A drive shaft 6 is rotatably connected to the fixed plate 22. The driven pulley 5 is coaxially fixedly connected to the drive shaft 6. A drive belt 7 is connected between the driving pulley 11 and the driven pulley 5. An eccentric wheel 12 is eccentrically fixedly connected to the drive shaft 6 and located below the hinge arm 18. A drive ring 21 is also fixedly connected below the hinge arm 18. The drive ring 21 is located directly above the eccentric wheel 12 and its axis is parallel to the eccentric wheel 12. When the rubber pad 20 contacts the upper end face of the gas storage tank body 1, the eccentric wheel 12 is at its lowest point.

[0031] The drive motor 9 can drive the driven pulley 5 through the active pulley 11 and the conveyor belt 7, thereby driving the eccentric wheel 12 to rotate through the transmission shaft 6, and then driving the hinge arm 18 to rotate around the fixed frame 15 through the drive ring 21. During this process, the vibrating hammer 19 moves up and down to hammer the surface of the gas storage tank body 1, so as to shake off the oil or water droplets attached to the inner wall of the gas storage tank body 1. Then, the drain valve 24 is opened to discharge waste liquid and water through the drain pipe 25.

[0032] The elastic element is designed so that when the eccentric wheel rotates to its highest point, it pushes the drive ring 21, causing the hinge arm 19 to lift around the hinge point of the fixed frame 15. When the eccentric wheel rotates to its lowest point, the pressure on the drive ring 21 is released, and the hinge arm 18 falls rapidly under its own weight and the action of the elastic element, causing the rubber pad 20 at the lower end of the vibrating hammer 19 to strike the surface of the gas storage tank body 1. In this reciprocating motion, the elastic element plays an important role: when the hinge arm is lifted, the elastic tube 16 and the spring 13 are compressed, thereby accumulating elastic potential energy; when the eccentric wheel moves away, the spring 13 is released. The elastic potential energy drives the articulated arm 18 and the vibrating hammer 19 to quickly reset and move in the opposite direction. The elastic element ensures that the articulated arm 18 can reliably return to its initial position in each vibration cycle and achieve continuous vibration by closely following the rotation of the eccentric wheel. At the same time, the elastic tube 16 provides a certain buffering effect, making the movement of the articulated arm smoother and preventing looseness or hard collisions. During the entire process, the vibrating hammer 19 repeatedly impacts the gas storage tank wall under the reset force of the spring 13, shaking off the water droplets and oil stains attached to the inner wall so that they can be discharged through the drain pipe 25 later.

[0033] In addition, a pressure detection sensor 23 is installed on the inner wall of the gas storage tank body 1, and an automatic pressure relief device is installed on the upper right side. The automatic pressure relief device is as follows: Figure 1 and Figure 5 As shown, the system includes a buffer housing 4, a pressure relief pipe 26, and a pressure relief valve 27. A pressure relief hole is provided on the upper right side of the gas storage tank body 1. The buffer housing 4 is fixedly connected to the right side of the gas storage tank body 1 by a fixing ring 3, and the interior of the buffer housing 4 is connected to the pressure relief hole. The pressure relief pipe 26 is connected to the buffer housing 4, and the pressure relief valve 27 is provided on the pressure relief pipe 26. The pressure detection sensor 23 monitors the gas pressure intensity inside the gas storage tank body 1. When the pressure exceeds the set safety threshold, the pressure relief valve 27 is opened to release pressure through the automatic pressure relief device to ensure the internal pressure of the gas storage tank body 1 is stable. Of course, this control process can be automatically controlled by a controller. The pressure detection sensor 23 and the pressure relief valve 27 are connected to the signal input terminal and signal output terminal of the controller, respectively, and the controller has a preset gas pressure safety threshold. The above-mentioned automatic control settings are conventional technical means in this field, so they will not be described in detail.

[0034] Furthermore, the automatic pressure relief device incorporates a buffer housing 4, which provides an additional volume. When high-pressure gas escapes, it is buffered within the buffer chamber, reducing the impact of sudden pressure drops on the tank and valves. This is equivalent to adding a buffer tank in the pressure relief path, using its volume to temporarily store high-pressure gas, thereby reducing the pressure peak of the discharge pipeline. Secondly, through the throttling effect of the pressure relief pipe 26, the gas in the buffer housing 4 is diverted and discharged, controlling the exhaust flow rate and speed, and preventing noise and danger caused by excessively rapid pressure relief.

[0035] During the use of the gas storage tank, the device first starts the air pump 2 to draw air from the air and send it into the gas storage tank body 1 for storage. During long-term use, the gas storage tank will become filled with water and oil. At this time, the drive motor 9 is started. The drive motor 9 drives the transmission shaft 6 to rotate through the belt 7. The transmission shaft 6 drives the eccentric wheel 12 to rotate. The eccentric wheel 12 continuously lifts and lowers the hinge arm 18 through contact with the drive ring 21. At the same time, the vibrating hammer 19 drives the rubber pad 20 to vibrate the gas storage tank body 1. The spring 13 plays the role of storing and releasing kinetic energy. Then, the drain valve 24 is opened to discharge waste liquid and water through the drain pipe 25. During the use of the gas storage tank body 1, the internal pressure detection sensor 23 detects the internal pressure value of the tank. When it exceeds the set safety threshold, the pressure relief valve 27 opens to release the pressure of the gas storage tank body 1 through the pressure relief pipe 26.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
