For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] Example 1

[0024] like Figure 1 As shown, the remotely replaceable air lift of this embodiment includes a flange 1, an air supply pipe 2, a delivery pipe 3 and a hook 4. The air supply pipe 2, the delivery pipe 3 and the hook 4 are all connected to the flange 1 to form an integral module that can be disassembled and transported together. The flange 1 is detachably connected to the opening of the liquid storage device 5. The air supply pipe 2 and the delivery pipe 3 both penetrate the flange 1 and extend into the liquid storage device 5. The air supply pipe 2 is connected to the delivery pipe 3 and is used to drive the liquid to be delivered to the liquid receiving device along the delivery pipe 3 by sending gas into the delivery pipe 3. The hook 4 is connected to the side of the flange 1 outside the liquid storage device 5 and is used to connect a lifting device to move the integral module.

[0025] The remotely replaceable air lift of this embodiment centrally installs separately arranged structural components such as the air supply pipe 2, the delivery pipe 3 and the hook 4 on the flange 1, thereby forming an integral module that can be disassembled and assembled and transported together. This arrangement makes the air lift itself more structurally integrated, and can be directly disassembled and assembled as an integral module, avoiding the tedious operation of separately disassembling and moving each component in the past, simplifying the operation process, and facilitating disassembly and installation. More importantly, since each structural component does not need to be disassembled and assembled separately, the air lift does not need to be manually completed during replacement. Delicate operations, but can be directly replaced remotely using tools such as master-slave manipulators and power arms, which is not only more efficient, but also suitable for use in radioactive environments such as high-level waste liquids to avoid radiation exposure to operators.

[0026] In this embodiment, the hook 4 is located at the center of the flange 1, and the air supply pipe 2 and the delivery pipe 3 are distributed on both sides of the hook 4, so that the equivalent center of gravity of the overall module is located in the vertical direction of the hook 4. This setting ensures that the lifting center coincides with the center of gravity of the overall module during lifting, thereby ensuring stability. The top heights of the air supply pipe 2 and the delivery pipe 3 are both lower than the top height of the hook 4, which is convenient for remote operation by a power hand.

[0027] In this embodiment, Figure 2 As shown, the lifter further includes bolts 6, which are used to fasten the flange 1 and the opening of the liquid storage device 5. Specifically, the flange 1 includes a fixed flange 11 and a movable flange 12. The fixed flange 11 is fixedly connected to the opening of the liquid storage device 5. The air supply pipe 2, the delivery pipe 3 and the hook 4 are all connected to the movable flange 12 to form an integral module. The bolts 6 are used to fasten the fixed flange 11 and the movable flange 12 after they are docked. There are multiple bolts 6, and each bolt 5 is evenly distributed on a circumference centered on the hook 4, so that the fastening connection position is more uniform.

[0028] The top end of the pipe body 37 of the conveying pipe 3 is bent to one side to form a bent section 31, and the bent section 31 is connected to the liquid receiving device. The conveying pipe 3 is used to convey the liquid to the liquid receiving device, so it needs to be connected to the jumper pipe and other pipelines. Considering the need to form a certain slope with the pipeline connected to the conveyed end when conveying liquid, and the valve, tee and other components described below need to be set at the discharge position of the conveying pipe 3, then the components set in conjunction with the top port of the conveying pipe 3 obviously have a larger spatial volume. In this embodiment, the top end of the conveying pipe 3 is bent. First, the space above is avoided, so that the hook 4 can be exposed, which is convenient for the upper lifting equipment to be connected. Secondly, the part with a larger spatial volume is bent to the side, so that each component has a layout space, which is convenient for arrangement and makes full use of the side space. At the same time, it is also convenient for the jumper pipe to form a certain slope in the opposite direction of the horizontal.

[0029] The air supply pipe 2, the hook 4 and the pipe body 37 are sequentially distributed in the same vertical plane, so that the projections of the three on the horizontal plane are located in the strip-shaped area passing through the center of the flange 1, and the projection of the bent section 31 of the delivery pipe 3 on the horizontal plane is located between two adjacent bolts 6, also in the strip-shaped area, and is bent toward the outside of the flange 1 with its back to the hook 4, so that the air supply pipe 2, the hook 4, the delivery pipe 3 and the top of the bolt 6 are not shielded. This layout scheme makes the overall layout of the air supply pipe 2, the hook 4, and the delivery pipe 3 a sheet-like module. First, this sheet-like module occupies very little space in the horizontal direction, does not affect the bolt layout, and leaves sufficient lateral operation avoidance space for the bolts. Secondly, the sheet-like module does not block the top of the bolts, so it does not affect the disassembly and installation operations of the power hand. More importantly, the structures in the sheet-like module do not block each other, and the power hand is fully capable of performing equipment connection operations on each pipe.

[0030] In this embodiment, three bolts 6 are provided, one of which is located at one end of the horizontal strip area away from the delivery pipe 3, and the other two are symmetrically distributed on both sides of the horizontal strip area, and the distance between each bolt 6 and the air supply pipe 2, the hook 4 or the delivery pipe 3 (the distance of any of the three) is not less than 20mm. The bolt 6 is a hexagonal bolt with a bolt diameter of M30.

[0031] In this embodiment, the lifter also includes a positioning pin 7 for positioning the flange 1 and the opening of the liquid storage device 5. Specifically, the positioning pin 7 and the pin hole can be respectively provided on the fixed flange 11 and the movable flange 12, and the positioning is achieved by aligning the two. There are multiple positioning pins 7, and each positioning pin 7 is evenly distributed on the circumference of the bolt 6, and each positioning pin 7 is located between two adjacent bolts 6.

[0032] In this embodiment, the remotely replaceable air lift also includes a support structure 36, which is supported and connected between the bending section 31 and the flange 1, and can play a supporting role and can be used to adjust the angle of the conveying pipe 3. The angle α formed by the bending section 31 and the pipe body 37 is not greater than 90°, so as to form the conveying slope of the subsequent jumper pipe. The support structure 36 is divided into two sections fixedly connected to each other, one section is horizontally arranged and fixedly connected to the flange 1, and the other section is vertically connected to the bending section 31. The vertical support method is not only more convenient for connection, but also has a better support effect, and can be welded.

[0033] In this embodiment, a first valve 32 is provided on the bending section 31 for controlling the delivery pipe 3 to discharge the material to the liquid receiving device.

[0034] In this embodiment, the bending section 31 is also provided with a second valve 33, a three-way pipe fitting 34 and a first quick plug 35. Two ports in the three-way pipe fitting 34 are respectively connected to the first valve 32 and the liquid receiving device. The second valve 33 is set at the other port, and the deionized water supply device is connected through the first quick plug 35, which can be connected to the deionized water pipeline to facilitate flushing of the pipeline and avoid pipeline blockage. The three-way pipe fitting 34 is connected to the liquid receiving device through a jumper pipe, and the high-level waste liquid flows to the liquid receiving device through the jumper pipe. The support structure 36 is supported at the bottom position of the three-way pipe fitting 34, so that the three ports of the three-way pipe fitting 34 and the bottom support structure 36 are in a cross-shaped structure. This cross-shaped structure makes the force on the support structure 36 more uniform.

[0035] In this embodiment, under normal working conditions, the first valve 32 is opened, the second valve 33 is closed, and compressed air is sent into the air supply pipe 2, and then the high-level waste liquid in the liquid storage equipment is lifted to the liquid delivery pipe 3, and finally delivered to the liquid receiving equipment through the first valve 21, the three-way pipe fitting 34, and the jumper pipe (not marked in the figure); when the jumper pipe is blocked or the pipeline is cleaned, the deionized water pipeline is connected to the first quick plug 35, the first valve 32 is closed, and the second valve 33 is opened, so that deionized water can enter the jumper pipe for flushing, thereby introducing deionized water to clean the pipeline or clear the blockage.

[0036] In this embodiment, a second quick plug 21 is provided at the top of the air supply pipe 2 for connecting to a gas supply device. The air supply pipe 2 is also called an air supply pipe. The gas supply device supplies compressed air. The air supply pipe is specifically connected to the compressed air pipeline (of the gas supply device) through the second quick plug 21 for easy plugging and unplugging.

[0037] In this embodiment, the bottom opening of the delivery pipe 3 is located at the bottom of the liquid storage device 5 and is immersed below the liquid level. The bottom end of the air supply pipe 2 is a concave arc-shaped curved section, the end of the arc-shaped curved section is connected to the delivery pipe 3, and the connection point is located above the bottom opening of the delivery pipe 3. The height of the end of the arc-shaped curved section in the air supply pipe 2 is not lower than the lowest concave point of the arc-shaped curved section, so that the gas passes into the delivery pipe 3 along the arc path. Under the pressure of the gas flow, the liquid in the liquid storage device 5 enters the delivery pipe 3 from the bottom opening of the delivery pipe 3, and the liquid rises along the delivery pipe 3 and is sent to the liquid receiving device.

[0038] The remotely replaceable air lift of this embodiment includes a flange 1 (flange 1 includes a fixed flange 11 and a movable flange 12 that are detachably connected to each other, the fixed flange 11 is fixedly connected to the opening of the liquid storage device 5, and the movable flange 12 is disassembled and assembled together with the air lift), and also includes an air supply pipe 2, a liquid delivery pipe 3 and a hook 4 arranged on the movable flange 12. The movable flange 12 is also provided with bolts 6 to connect and fix the air lift and the liquid storage device 5. Generally speaking, it has the following beneficial effects:

[0039] 1. Remote operation can be achieved, and workers do not have to approach high-radioactive environments;

[0040] 2. Simple structure, small size, can be used in narrow operating environment;

[0041] 3. The liquid feed pipe 3 is provided with two valves. When the pipe is blocked, the second valve 33 for controlling water can be opened, and the first valve 32 for controlling liquid feed can be closed to flush the pipe (jumper pipe) and prevent water from flowing back to the raw liquid storage device 5.

[0042] The remotely replaceable air lift of this embodiment can be used for fluid transport equipment. Due to the above characteristics, it can be applied to the transportation of high-level liquid waste. As a remotely replaceable air lift used in a radioactive environment, the device can be placed in a device containing high-level liquid waste, and can transport the high-level liquid waste from one device to another; and when the air lift needs to be repaired or replaced, it can be replaced remotely through tools such as master-slave manipulators and power arms to avoid radiation exposure to operators.

[0043] During disassembly, first use a power hand to loosen each bolt 6, use a power hand to unplug the compressed air pipeline connected to the second quick plug 21, use a power hand to unplug the deionized water pipeline connected to the first quick plug 35, use a power hand to remove the jumper tube (not shown in the figure), and finally use a power hand to connect the hook 4 to remove the air lift from the liquid storage device 5.

[0044] During installation, use a power hand to connect the hook 4, place the air lifter into the liquid storage device 5, use a power hand to tighten the bolts 6, use a power hand to connect the compressed air pipeline with the second quick plug 21, use a power hand to connect the deionized water pipeline with the first quick plug 35, and use a power hand to install the jumper pipe.

The air lift that can be replaced remotely is installed on the feed tank, and the delivery pipe 3 is connected to the glass solidification furnace through a jumper pipe to deliver the liquid in the feed tank to the glass solidification furnace. When the air lift is used in the glass solidification equipment, the air supply pipe 2 of the air lift passes compressed air and is connected by a hose with a quick connector.

[0048] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
