Description

Technical Field

[0001] The utility model relates to the technical field of air buffer tanks, in particular to a high-protection compressed air buffer tank. Background Art

[0002] A diaphragm-type compressed air buffer tank is a commonly used buffer tank. A diaphragm is fixed to the bottom of the buffer tank by a steel ring. The space above the diaphragm inside the buffer tank is filled with compressed air. The space below the diaphragm inside the buffer tank is connected to a branch pipe of an external water supply pipeline (or other things that need to buffer system pressure fluctuations, such as central air conditioning systems). Sudden start-up, stop or failure of the pump, as well as changes in the water flow rate in the pipeline, can cause water hammer in the pipeline. The up and down movement of the diaphragm in the compressed air can alleviate the impact of the water hammer effect on the pipeline.

[0003] The buffer tank includes a tank body with tank covers welded and fixed at both ends. When the weld is subjected to periodically changing compressed air pressure or water pressure, fatigue will occur. Fatigue will cause cracks to form inside the weld metal. Long-term use and crack expansion can easily lead to leakage. However, the weld positions of most compressed air buffer tanks lack protective measures, which is not conducive to the safe use of the buffer tank. In addition, a filter structure that purifies impurities in the air is generally installed at the air inlet pipe position of the buffer tank to prevent dirty air from entering the buffer tank to protect the internal structure of the buffer tank. However, when cleaning the filter structure, it is not easy for the air inlet pipe to continuously supply air to the buffer tank. Utility Model Content

[0004] The purpose of the present utility model is to provide a highly protected compressed air buffer tank to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] High protection compressed air buffer tank, including:

[0007] A tank body, wherein a diaphragm is fixed to the inner bottom of the tank body, the bottom of the tank body is connected and fixed to an external water pipe, and the outer side of the tank body is connected and fixed to an air inlet pipe;

[0008] Two protective sleeves are detachably fixed to the outside of the welds at both ends of the tank body. The protective sleeves include two symmetrically distributed semicircular shells, and bolts are detachably fixed between the two ends of the two semicircular shells.

[0009] The filtering mechanism is connected and fixed at one end of the air intake pipe. The filtering mechanism includes an arc-shaped support plate. The inner side of the arc-shaped support plate is rotatably connected to a rotating column. The outer side of the rotating column is provided with two mounting holes. One end of the mounting hole is screwed and connected to a threaded tube. One end of the threaded tube is connected and fixed to a rubber tube. The interior of the threaded tube and the rubber tube are both filled with activated carbon particles.

[0010] Furthermore, the inner top of the tank body is connected to and provided with a pressure relief valve, and the outer side of the top of the tank body is fixedly provided with a pressure gauge.

[0011] Furthermore, a steel ring fixedly connected to the diaphragm is fixed inside the tank body, and a connecting pipe 1 fixedly connected to an external water pipe is connected to the bottom of the tank body.

[0012] Furthermore, a sealing gasket 1 is sleeved and fixed on the inner side of the semicircular shell, and a sealing gasket 2 is sleeved and fixed on both ends of the semicircular shell.

[0013] Furthermore, a second barometer is fixedly mounted on the outer side of one of the protective covers, and a water immersion sensor is fixedly mounted on the outer side of the other protective cover.

[0014] The invention further comprises: an L-shaped rod is fixed between the tank body and the arc-shaped supporting plate; two connecting pipes 2 are plugged and fixed on the outer side of the arc-shaped supporting plate; and one connecting pipe 2 is connected and fixed to the air intake pipe.

[0015] Furthermore, the middle portion of the mounting hole is bent, the rubber tube is arranged at the bent position of the mounting hole, and an adjusting wheel is fixed on the outer side of the rotating column.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Two semicircular shells are fixed to the welds of the buffer tank body by bolts. The semicircular shells protect the welds and, to a certain extent, prevent the welds from being exposed to a humid and oxygen-rich environment for a long time, thereby reducing the occurrence of corrosion and leakage at the welds. When the welds on the top of the tank body leak due to long-term exposure to air pressure, the leaked gas gathers inside the protective cover composed of the two semicircular shells. Observe the pressure reading on the pressure gauge on the protective cover. When the pressure reading increases, it indicates that the weld is leaking gas.

[0018] Similarly, a protective sleeve composed of two semicircular shells is connected to the weld position at the bottom of the tank body. When the weld at this position leaks due to long-term water pressure, water will leak into the inside of the protective sleeve. The existing water immersion sensor can detect whether there is water leakage inside the protective sleeve, thereby using the protective sleeve to protect the weld of the tank body. Even if the weld leaks, the protective sleeve can isolate air and water, which is beneficial to improve the safety of the compression tank.

[0019] 2. An arc-shaped support plate is arranged at the air inlet of the air inlet pipe. A rotating column rotates inside the arc-shaped support plate. Two filter pipes consisting of threaded pipes and rubber pipes are detachably plugged and fixed inside the rotating column. The filter pipes are filled with activated carbon particles. In the initial state, the external air source passes through the activated carbon particles in one of the filter pipes to filter impurities in the air, absorb moisture in the air, and then transport it to the air inlet pipe, so that the gas entering the buffer tank remains dry and clean.

[0020] When cleaning the filter pipe that is saturated with dust and water, the rotating column is rotated 90 degrees by rotating the adjusting wheel, so that the second filter pipe is transferred to the air inlet position of the intake pipe to replace the first filter pipe to purify the air. At the same time, the threaded tube of the second filter pipe rotates with the rotating column to the top opening of the arc support. The threaded tube is loosened to facilitate the removal of the saturated filter pipe and replacement of the new filter pipe, so that the intake pipe can continue to transport clean air to the inside of the tank during the removal and replacement of the filter pipe.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] For example 1, please refer to Figure 1 - Figure 6 In the embodiment of the present invention, a high-protection compressed air buffer tank includes a tank body 100, a diaphragm 110 is fixed to the inner bottom of the tank body 100, the bottom of the tank body 100 is connected and fixed with an external water pipe, and an air inlet pipe 120 is connected and fixed to the outside of the tank body 100. The outer sides of the weld positions at both ends of the tank body 100 are detachably covered with protective sleeves 200, and the protective sleeves 200 include two symmetrically distributed semicircular shells 210, and a screw is detachably fixed between the two ends of the two semicircular shells 210. Plug 220, one end of the air intake pipe 120 is connected to a filter mechanism 300, the filter mechanism 300 includes an arc-shaped support plate 310, the inner side of the arc-shaped support plate 310 is rotatably connected to a rotating column 320, the outer side of the rotating column 320 is provided with two mounting holes 321, one end of the mounting hole 321 is screwed and connected to a threaded tube 330, one end of the threaded tube 330 is connected and fixed to a rubber tube 340, and the interior of the threaded tube 330 and the rubber tube 340 are both filled with activated carbon particles 331.

[0030] Specifically, by sleeve-fixing the protective cover 200 at the weld position of the buffer tank, the protective cover 200 can protect the weld position while detecting whether there is air leakage or water leakage at the weld position with the help of the existing pressure gauge and water immersion sensor 215, which is beneficial to improving the safety of the use of the buffer tank. By rotating a rotating column 320 at the position of the air intake pipe 120 of the tank body 100, two filter pipes with staggered arrangement paths are installed inside the rotating column 320. The filter pipe is composed of a threaded pipe 330 and a rubber pipe 340 that are connected and fixed. The activated carbon particles 331 inside the filter pipe can purify the air entering the air intake pipe 120, allowing clean air to enter the tank body 100, which is beneficial to protecting the internal structure of the tank body 100 and further improving the protectiveness of the tank body 100. When replacing the filter pipe saturated with dust, the two filter pipes can be exchanged by rotating the rotating column 320, so that the spare filter pipe can continue to purify the air while the dust-saturated filter pipe is removed, and the air intake pipe 120 continuously delivers clean air to the inside of the tank body 100.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, a pressure relief valve 130 is installed on the inner top of the tank body 100, and the pressure relief valve 130 can discharge the high-pressure air inside the tank body 100. A pressure gauge 140 is fixed on the outer side of the top of the tank body 100, and the pressure gauge 140 monitors the air pressure inside the tank body 100 in real time. The bottom of the tank body 100 is connected to and fixed with a connecting pipe 160 that is connected to an external water pipe.

[0032] In this embodiment, when the water pressure in the external water pipe increases, part of the water flow will enter the position below the diaphragm 110 inside the tank body 100 through the connecting pipe 160, causing the diaphragm 110 to move upward to squeeze the compressed air at the top of the tank body 100. The high-pressure air inside the tank body 100 will be discharged along the exhaust pipe outside the pressure relief valve 130. Then, after the water pressure inside the external water pipe returns to a stable state, the air inlet pipe 120 continues to supply air to the inside of the tank body 100, so that the inside of the tank body 100 reaches a certain air pressure to maintain the stability of the water pressure in the external water pipe.

[0033] like Figure 2 As shown, in this embodiment, a steel ring 150 fixedly connected to the diaphragm 110 is fixed inside the tank body 100 , so that the diaphragm 110 is firmly installed and fixed inside the tank body 100 .

[0034] like Figure 3 As shown, in this embodiment, a sealing gasket 1 211 is sleeved and fixed on the inner side of the semicircular shell 210, and a sealing gasket 212 is sleeved and fixed on both ends of the semicircular shell 210. When the two semicircular shells 210 are fixedly combined into the protective sleeve 200 by bolts 220, the sealing gasket 1 211 can make the protective sleeve 200 seal against the outer side of the tank body 100, and the sealing gasket 212 can make the ends of the two semicircular shells 210 seal against each other, thereby ensuring the sealing of the internal space of the protective sleeve 200.

[0035] In this embodiment, connecting ears 213 are fixed at both ends of the semicircular shell 210. Two adjacent connecting ears 213 are convenient for plugging and fixing with bolts 220, so that the two semicircular shells 210 are combined and fixed together.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, an L-shaped rod 170 is fixed between the tank body 100 and the arc-shaped support plate 310, so that the arc-shaped support plate 310 is fixed to the outside of the tank body 100, and two connecting pipes 311 are plugged and fixed to the outside of the arc-shaped support plate 310, one connecting pipe 311 is connected to the air intake pipe 120, one connecting pipe 311 is connected to the pipe for transporting air from the outside, and the other connecting pipe 311 is connected to the air intake pipe 120.

[0037] like Figure 4 - Figure 6As shown, in this embodiment, the middle part of the mounting hole 321 is bent, and the rubber tube 340 is arranged at the bent position of the mounting hole 321, so that the two rubber tubes 340 can be staggered in the middle part of the rotating column 320 to prevent the two filter pipes composed of the threaded tube 330 and the rubber tube 340 from interfering with each other during installation. An adjusting wheel 350 is fixed to the outside of the rotating column 320 to facilitate the connection of the filter pipes at different positions inside the rotating column 320 to the end of the air inlet pipe 120 to filter the air. The inside of the filter pipe can also be filled with other air purifying materials, and the specific materials are selected according to needs.

[0038] In this embodiment, a toggle block 332 is fixed inside the threaded tube 330. Turning the toggle block 332 makes it convenient for the user to rotate the threaded tube 330. The rubber tube 340 is soft and can adapt to the curved installation hole 321 for installation in a curved position. A mesh bag can be used to hold the activated carbon particles 331, and then the mesh bag can be placed inside the filter pipe to prevent the activated carbon particles 331 from escaping from the filter pipe.

[0039] like Figure 1 As shown, in this embodiment, a plurality of rubber columns 400 are detachably fixed at equal intervals between the two protective sleeves 200 . The rubber columns 400 can protect the surrounding side of the tank body 100 to prevent the tank body 100 from being damaged by external physical impact.

[0040] Embodiment 2, based on embodiment 1, is designed to assist users in detecting whether there is air leakage or water leakage at the welding seam.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, a second pressure gauge 214 is fixedly mounted on the outer side of one protective cover 200 , and a water immersion sensor 215 is fixedly mounted on the outer side of the other protective cover 200 .

[0042] In this embodiment, when the weld at the top of the tank body 100 leaks, the gas will flow into the inside of the protective cover 200 equipped with the second pressure gauge 214, and the reading of the second pressure gauge 214 will increase. The observation that the reading of the second pressure gauge 214 increases indicates that the weld is leaking; when the weld at the bottom of the tank body 100 leaks, water will flow into the inside of the protective cover 200 equipped with the water immersion sensor 215 detection probe, and the water immersion sensor 215 will alarm, indicating that the weld is leaking. The water immersion sensor 215 and the pressure gauge are both existing technical components, and the specific working principles will not be elaborated on.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
