Description

Technical Field

[0001] This utility model relates to the technical field of anti-blocking and unblocking tools for connecting pipes of formation water tanks, and particularly to a pneumatic unblocking device for atmospheric pressure formation water tanks. Background Technology

[0002] Formation water tanks, as an important component of wastewater treatment systems, collect and buffer wastewater generated during the gas-liquid separation process of natural gas. To indicate the wastewater level, level gauges are typically installed on the outside of the formation water tank. For example... Figure 1 The vertical level gauge shown below operates on the following basic principle:

[0003] The measuring tube has a longitudinally arranged display bar with multiple color marks arranged vertically on it. The opposite sides of each color mark are designated with a first and second color, such as red and white. Color marks of the same color have the same magnetic properties, while those of different colors have opposite magnetic properties. For example, when the red color mark has the north pole, the white color mark has the south pole. Inside the measuring tube, there is a float that floats on the liquid surface and moves up and down with the liquid level. The float is magnetic and couples with the magnetic color marks, causing the color marks to flip (red indicates the presence of liquid, white indicates the absence of liquid). The red-white boundary on the display bar indicates the actual liquid level in the container.

[0004] However, the measuring tube of the level gauge is connected to the formation water tank via a connecting pipe. During the storage of sewage in the formation water tank, sediment will settle, causing the connecting pipe connected to the bottom of the formation water tank to become blocked. This leads to the level gauge display being distorted, making it impossible for staff to accurately grasp the sewage level. Utility Model Content

[0005] This utility model provides a pneumatic unblocking device for atmospheric pressure formation water tanks, which can be used to unblock the connecting pipe on the formation water tank used to connect the level gauge when the pipe becomes blocked.

[0006] This utility model provides a pneumatic unblocking device for an atmospheric pressure formation water tank, wherein a connecting pipe is provided between the formation water tank and the level gauge, and the pneumatic unblocking device includes:

[0007] Lifting support;

[0008] An air pump is installed on the lifting bracket. The air pump has a first one-way valve at the air inlet for communicating with the outside and a second one-way valve at the air outlet.

[0009] An air tank is fitted onto the cylinder of the air pump, and the air tank and the air pump are connected in one direction only through the second one-way valve;

[0010] The gas supply pipe has an inlet end connected to the outlet end of the gas storage tank and an outlet end connected to the connecting pipe. A valve is installed on the gas supply pipe.

[0011] In one embodiment, the gas storage tank extends longitudinally and has mounting holes at both ends of the axial direction, and the cylinder of the air pump is sealed through the mounting holes.

[0012] The air inlet of the air pump is located on the bottom wall of the cylinder, and the air outlet of the air pump is located on the side wall of the cylinder.

[0013] In one embodiment, a sealing ring is provided between the inner wall of the mounting hole and the outer wall of the cylinder.

[0014] In one embodiment, the gas volume of the gas storage tank is smaller than the gas volume of the inner cavity of the cylinder.

[0015] In one embodiment, a pressure gauge is connected to the gas storage tank, and the pressure gauge is used to measure the gas pressure inside the gas storage tank.

[0016] In one embodiment, the gas supply pipe is a pressure-resistant flexible hose.

[0017] In one embodiment, an adapter is provided at one end of the gas supply pipe for connecting to the connecting pipe, and the gas supply pipe is connected to the unblocking end of the connecting pipe through the adapter.

[0018] In one implementation, the connecting pipe is a three-way pipe, and the three ports on the connecting pipe are respectively connected to the level gauge, the formation water tank, and the gas transmission pipe.

[0019] In one embodiment, a piston rod is provided axially and telescopically inside the cylinder, a piston is installed at one end of the piston rod inside the cylinder, and a handle is provided at the other end of the piston rod outside the cylinder.

[0020] In one embodiment, the lifting support includes:

[0021] The cylindrical body is fixedly mounted on the support platform.

[0022] An adjustable lifting mechanism; a support is provided below the support platform and is used to adjust the height of the support platform.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] 1. Close the valve and operate the air pump to continuously fill the air tank. When the compressed gas in the air tank reaches a certain pressure, open the valve. The compressed gas in the air tank will be discharged into the connecting pipe through the air delivery pipe, thereby stably clearing the connecting pipe.

[0025] Because the air pump has a first one-way valve at the inlet, external gas can only enter the pump through this valve, while the gas inside the pump cannot be discharged through the inlet. Because the air pump has a second one-way valve at the outlet, compressed gas from the storage tank cannot flow back into the pump. This ensures unidirectional gas flow and prevents backflow.

[0026] In addition, the air pump in this embodiment is mounted on a lifting bracket, which can raise and lower the air pump to adjust its height so as to accommodate operators of different heights.

[0027] 2. The gas storage tank and cylinder are made of metal, and the inner wall of the mounting hole is sealed with the outer wall of the cylinder to ensure the sealing requirements at the connection.

[0028] 3. The gas volume of the gas storage tank is smaller than the gas volume of the inner cavity of the cylinder, so that the gas inside the cylinder is effectively compressed after entering the gas storage tank, thereby increasing the gas pressure inside the gas storage tank efficiently and quickly.

[0029] 4. The basic principle of the pneumatic unblocking device in this embodiment is as follows:

[0030] The basic principle of the unblocking device in this embodiment is as follows:

[0031] First, install the air pump on the lifting bracket, connect the air outlet of the air supply pipe to the connecting pipe, and close the valve on the air supply pipe.

[0032] Then, operate the air pump to continuously fill the air tank with gas: pull the handle upwards, and the piston, driven by the piston rod, expands the second chamber, allowing external gas to enter the second chamber through the first one-way valve; then, press the handle downwards, and the piston, driven by the piston rod, compresses the second chamber, expelling the compressed gas in the second chamber through the second one-way valve into the air tank. Repeat the above operation to continuously fill the air tank with gas.

[0033] Once the gas pressure in the gas storage pipe reaches the preset pressure, open the valve on the gas delivery pipe. The pressurized gas in the gas storage tank can then be discharged through the gas delivery pipe into the connecting pipe, thereby clearing the blockage in the connecting pipe.

[0034] 3. In this embodiment, since the cylinder extends vertically, the handle is located above the cylinder, and the first chamber is located above the second chamber.

[0035] With this configuration, the piston can be pressed down to compress the gas in the second chamber, making it easy to press.

[0036] 4. In this embodiment, the gas supply pipe is a pressure-resistant flexible hose.

[0037] If the air supply pipe is a rigid, inflexible tube, the unblocking device is limited by the size and relative position of the unblocking site, which is very inconvenient. However, using a flexible hose as the air supply pipe allows for bending, expanding the operating position of the air pump, making it more flexible and convenient. Attached Figure Description

[0048] Appendix Figure 1 In this system, the atmospheric pressure formation water tank 100 and the level gauge 200 are connected by a connecting pipe 300. When sludge settles inside the formation water tank 100, the connecting pipe 300 may become blocked, leading to distortion in the level gauge 200 reading. To address the aforementioned technical problems in the prior art, this embodiment of the invention provides a pneumatic unblocking device for atmospheric pressure formation water tanks, used to unblock the connecting pipe 300, thereby ensuring the accuracy of the liquid level height measured by the level gauge 200 inside the formation water tank 100.

[0049] The present invention will be further described below with reference to the accompanying drawings.

[0050] In this embodiment of the utility model, the pneumatic unblocking device for the atmospheric pressure formation water tank 100 includes a lifting bracket 1, an air pump 2, an air storage tank 3, and an air supply pipe 4.

[0051] The air pump 2 is mounted on the lifting bracket 1, which can raise and lower the air pump 2 to adjust its height to accommodate operators of different heights. The specific structure of the lifting bracket 1 will be described in detail later.

[0052] The air inlet of the air pump 2 is connected to the outside, and a first one-way valve 25 is provided at the air inlet of the air pump 2. External gas can only enter the air pump 2 in one direction through the first one-way valve 25, while the gas inside the air pump 2 cannot be discharged from the air inlet.

[0053] A second one-way valve 26 is installed at the air outlet of the air pump 2; the air tank 3 is sealed and fitted onto the air pump 2, and the air tank 3 and the air pump 2 are connected in one direction only through the second one-way valve 26; this prevents the compressed gas in the air tank 3 from flowing back into the cylinder 21 of the air pump 2. In this way, the gas is guaranteed to flow in one direction and backflow is avoided.

[0054] A pressure gauge 7 is connected to the gas storage tank 3, and the pressure gauge 7 is used to measure the gas pressure inside the gas storage tank 3.

[0055] The inlet end of the gas pipeline 4 is connected to the outlet end of the gas storage tank 3, and the outlet end of the gas pipeline 4 is connected to the connecting pipe 300. A valve 6 is installed on the gas pipeline 4. The valve 6 can be a ball valve or a check valve.

[0056] Close valve 6 and operate air pump 2 to continuously fill air tank 3. When the compressed gas in air tank 3 reaches a certain pressure, open valve 6 and the compressed gas in air tank 3 is discharged into connecting pipe 300 through air delivery pipe 4, thereby stably clearing the connecting pipe 300.

[0057] In this embodiment, the specific connection method between the air pump 2 and the air tank 3 is as follows.

[0058] The air tank 3 extends longitudinally and has mounting holes 31 at both ends of the axial direction. The cylinder 21 of the air pump 2 is sealed through the mounting holes 31. The air inlet of the air pump 2 is located on the bottom wall of the cylinder 21, and the air outlet of the air pump 2 is located on the side wall of the cylinder 21.

[0059] The gas storage tank 3 and the cylinder 21 are made of metal. The inner wall of the mounting hole 31 and the outer wall of the cylinder 21 are sealed by welding to ensure the sealing requirements at the connection.

[0060] The gas volume of the gas storage tank 3 is smaller than the gas volume of the inner cavity of the cylinder 21, so that the gas in the cylinder 21 is effectively compressed after entering the gas storage tank 3, thereby increasing the gas pressure in the gas storage tank 3 efficiently and quickly.

[0061] The following is an explanation of pump 2.

[0062] In this embodiment, the air pump 2 includes a cylinder 21, a piston rod 22, a piston 24, and a handle 23.

[0063] The air inlet and outlet of the air pump 2 are both located on the cylinder body 21, which extends vertically. The bottom wall of the cylinder body 21 is fixedly installed on the lifting bracket 1 by fixing bolts 8.

[0064] The piston rod 22 is axially telescopically mounted on the cylinder 21, and the piston 24 is mounted on the piston rod 22 at one end inside the cylinder 21. The piston 24 axially divides the inner cavity of the cylinder 21 into a first chamber 2101 and a second chamber 2102 arranged vertically and not connected to each other; the air inlet of the air pump 2 is located on the bottom wall of the cylinder 21, and the air outlet of the air pump 2 is located on the side wall of the second chamber 2102.

[0065] The piston 24 is made of rubber. The outer peripheral wall of the piston 24 is press-fitted with the inner wall of the cylinder 21, thereby ensuring that the first chamber 2101 and the second chamber 2102 are not connected to each other.

[0066] The handle 23 is located on the piston rod 22 at one end outside the cylinder 21 and above the cylinder 21. The handle 23 can be a horizontal bar, which is perpendicular to the piston rod 22. By applying pressure to the horizontal bar with both hands, the handle 23 can be easily pulled or pressed down, causing the piston rod 22 to extend and retract; pressing down on the handle 23 causes the piston 24 to compress the gas in the second chamber 2102, making it easy to press.

[0067] The basic principle of the pneumatic unblocking device in this embodiment is as follows:

[0068] First, install the air pump 2 on the lifting bracket 1, connect the air outlet of the air supply pipe 4 to the connecting pipe 300, and close the valve 6 on the air supply pipe 4.

[0069] Then, the air pump 2 is operated to continuously fill the air tank 3 with gas: pulling the handle 23 upward causes the piston 24, driven by the piston rod 22, to expand the second chamber 2102, allowing external gas to enter the second chamber 2102 through the first one-way valve 25; then, pressing the handle 23 downward causes the piston 24, driven by the piston rod 22, to compress the second chamber 2102, and the compressed gas in the second chamber 2102 is discharged into the air tank 3 through the second one-way valve 26. Repeating the above operation allows for continuous filling of the air tank 3 with gas.

[0070] When the gas pressure in the gas storage pipe reaches the preset pressure, the valve 6 on the gas delivery pipe 4 is opened, and the pressurized gas in the gas storage tank 3 can be discharged into the connecting pipe 300 through the gas delivery pipe 4, thereby clearing the blockage of the connecting pipe 300.

[0071] In this embodiment, the air supply pipe 4 is a pressure-resistant flexible hose. If the air supply pipe 4 were a rigid, inflexible pipe, the unblocking device would be limited by the size and relative position of the unblocking site, which would be very inconvenient. However, using a flexible hose as the air supply pipe 4 allows for bending, expanding the operating position of the air pump 2, making it more flexible and convenient.

[0072] An adapter 5 is provided at one end of the gas supply pipe 4 for connecting to the connecting pipe 300. The gas supply pipe 4 is connected to the unblocking end of the connecting pipe 300 through the adapter 5.

[0073] The connecting pipe 300 is a three-way pipe, and the three ports on the connecting pipe 300 are respectively connected to the level gauge 200, the formation water tank 100, and the gas transmission pipe 4.

[0074] The specific structure of the lifting support 1 is described below.

[0075] The lifting support 1 includes a support platform 11 and an adjustable lifting mechanism that is positioned below the support platform 11.

[0076] Bolts 8 are welded to the bottom wall of the cylinder 21. After the bolts 8 are passed through the threaded holes on the support platform 11 from top to bottom, the bolts 8 are tightened with nuts, so that the air pump 2 can be fixed on the support platform 11.

[0077] A vent is provided at the center of the support platform 11, so that the air inlet at the bottom of the cylinder 21 is opposite to the vent, so as to ensure that external gas can enter the inner cavity of the cylinder 21 through the air inlet.

[0078] As a first implementation method, the adjustable lifting mechanism is a scissor lift mechanism.

[0079] In a second embodiment, the adjustable lifting mechanism includes a longitudinally arranged telescopic rod 12 and a sleeve 13 coaxially sleeved outside the telescopic rod 12. The fixed ends of the telescopic rod 12 and the sleeve 13 are installed one-to-one on the support platform 11 and the base 15, and the other ends of the telescopic rod 12 and the sleeve 13 are sleeved together.

[0080] Multiple first positioning holes 121 are arranged at intervals along the axial direction on the telescopic rod 12, and multiple second positioning holes 131 are arranged at intervals along the axial direction on the sleeve 13. By moving the telescopic rod 12 up and down inside the sleeve 13, the first positioning holes 121 on the telescopic rod 12 can be aligned with the different second positioning holes 131 on the sleeve 13, so as to adjust the length of the telescopic rod 12 extending into the sleeve 13, that is, to adjust the relative distance between the support platform 11 and the base 15, thereby adjusting the height of the support platform 11 and the air pump 2 on it.

[0081] Once the support platform 11 is adjusted to the appropriate height, a positioning pin 14 is passed sequentially through the aligned second positioning hole 131 and the first positioning hole 121 to limit the support platform 11 to that height. The positioning pin 14 has an interference fit with the wall of the positioning hole.

[0082] Wheel brackets 16 are installed at the four corners of the bottom of the base 15, and each wheel bracket 16 contains a caster wheel 17. Brake pads 18 are installed on at least two wheel brackets 16. The brake pads 18 are located on the upper side of the caster wheel 17. The side of each brake pad 18 closest to the caster wheel 17 is made of rubber. The brake pads 18 can be engaged with the caster wheel 17 to restrict the rotation of the caster wheel 17, and allow the caster wheel 17 to rotate after contact engagement.

[0083] When in use, the user can push the lifting bracket 1 and the air pump 2 on it to the desired working position, and then press the brake pad 18 to prevent the air pump 2 from moving while pumping air, thus improving stability.

[0084] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
