Description

Technical Field

[0001] The present application belongs to the technical field of decomposition tank air duct serial connection, and specifically relates to a decomposition tank air duct connection tool. Background Art

[0002] The decomposition tank is a key piece of equipment in the Bayer process for producing aluminum hydroxide. During the production process, sodium aluminate solution is decomposed at a gradient temperature, and aluminum hydroxide seeds are added simultaneously to increase the decomposition rate and accelerate the precipitation of aluminum hydroxide particles. The decomposition tank is typically equipped with multiple ducts for compressed air. Some ducts are emergency compression ducts, which extend to the bottom of the decomposition tank to stir the material inside and prevent sedimentation. Other ducts are feed ducts, which typically have multiple holes at the top of the decomposition tank. These ducts are then lowered into the bottom of the tank to press the material out of the decomposition tank.

[0003] Due to the high height of the decomposition tank, each air duct is often installed inside the decomposition tank by connecting multiple pipes in series. This duct ventilation is used to agitate or lift the materials in the decomposition tank. Traditionally, a pipe clamp is used to clamp the lower pipe, weld the upper pipe to the lower pipe, and then release the clamp to feed the two connected pipes into the decomposition tank. The pipes are then connected in series until multiple pipes are connected.

[0004] This traditional pipe connection method is time-consuming and affects the efficiency of pipe installation. Summary of the Invention

[0005] In order to solve the current technical problem of low pipeline connection efficiency, the present application provides a decomposition tank air duct connection tool.

[0006] In a first aspect of the present application, a decomposition tank air duct connection tool is provided for serially connecting a first air duct and a second air duct, comprising:

[0007] A support frame is provided at the top of the decomposition tank, the top of the tank is provided with a first through hole, the support frame is provided with a second through hole for the first air duct to extend into, and the first through hole is connected to the second through hole;

[0008] a clamping assembly for clamping the first air duct, the clamping assembly being placed on the support frame so as to be rotatable relative to the support frame, thereby switching between a first position and a second position;

[0009] A hoisting mechanism, used for hoisting the first air duct and the second air duct;

[0010] In which, when the clamping assembly is in the first position, the clamping assembly abuts against the top of the support frame; when the clamping assembly is in the second position, the projection of the clamping assembly in the vertical direction falls within the first through hole and the first through hole, so that the clamping assembly and the first air duct pass through the second through hole and the first through hole together.

[0011] In some embodiments, the support frame is provided with a limiting groove, the limiting groove is communicated with the second through hole, and when the clamping assembly is located at the first position, the clamping assembly is at least partially located in the limiting groove.

[0012] In some embodiments, the limiting groove is a rectangular groove.

[0013] In some embodiments, the second via hole is a rectangular hole, the size of the clamping assembly along its length direction is larger than the wide side size of the rectangular hole, and the size of the clamping assembly along its width direction is smaller than the short side size of the rectangular hole.

[0014] In some embodiments, the long side of the rectangular groove and the long side of the rectangular hole are perpendicular to each other.

[0015] In some embodiments, the clamping assembly includes a clamping plate and a threaded member, two of each of the clamping plate and the threaded member are provided, the two clamping plates are connected by a threaded member, and the two threaded members and the two clamping plates enclose a clamping cavity for clamping the first air duct.

[0016] In some embodiments, the splint includes a connecting section and a clamping section, and there are two connecting sections. The clamping section is located between the two connecting sections. The connecting sections of the two splints are connected by the screw member, and the inner side surface of the clamping section is an arc surface that matches the shape of the first air duct.

[0017] In some embodiments, the connecting section extends along a length direction of the clamping assembly, and the screw member extends along a width direction of the clamping assembly.

[0018] In some embodiments, flanges are provided at the ends of the first air duct and the second air duct, the clamping assembly is located below the flange of the first air duct, and the two flanges are screwed together.

[0019] In some embodiments, the bottom of the support frame is provided with anti-slip grooves.

[0020] According to the embodiment of the present application, the decomposition trough air duct connection tooling provided is used to connect the first air duct and the second air duct in series. The decomposition trough air duct connection tooling includes a support frame, a clamping assembly and a hoisting mechanism. The support frame is arranged at the top of the decomposition trough, and the top of the trough is provided with a first through hole, and the support frame is provided with a second through hole connected to the first through hole; the clamping assembly is used to clamp the first air duct, and the clamping assembly is placed on the support frame so that the clamping assembly can rotate relative to the support frame, thereby switching between the first position and the second position; the hoisting mechanism is used to hoist the first air duct and the second air duct, and when the hoisting structure hoists the second air duct, the second air duct is aligned with the first air duct.

[0021] The support frame is placed on the top of the decomposition tank, so that the space inside the decomposition tank forms a space for accommodating the first air duct and the second air duct. During the process of connecting the first and second air ducts in series, the clamping assembly is pre-connected to the first air duct. The lower end of the first air duct is then fed into the decomposition tank through the second through-hole of the support frame and the first through-hole of the decomposition tank using a lifting mechanism. The clamping assembly is placed on the support frame and in the first position, thereby achieving stable support for the first air duct. Then the lifting mechanism releases the first air duct and then lifts the second air duct, which can drive the second air duct to adjust its position and posture so that the lower end of the second air duct is connected to the upper end of the first air duct. At this time, the first air duct and the second air duct can be connected. After the connection between the two is completed, the lifting mechanism rotates and at the same time drives the clamping assembly, the first air duct and the second air duct to rotate relative to the support frame, so that the clamping assembly, the first air duct and the second air duct are rotated until the projection of the clamping assembly in the vertical direction falls within the first through hole and the first through hole, that is, the clamping assembly is in the second position, and then the lifting mechanism slowly moves the second air duct downward, and the first air duct and the clamping assembly pass through the second through hole of the support frame and the first through hole on the top of the decomposition trough together to fall into the space inside the decomposition trough or below the decomposition trough platform, thereby quickly completing the series connection of the first air duct and the second air duct.

[0022] Compared with the traditional method of using a pipe clamp to fix the lower pipe, connecting the upper pipe and the lower pipe and then loosening the pipe clamp, the present application can fix the clamping component to the lower pipe in advance, which does not take up the installation time of the pipe and the decomposition tank. When there is a need to connect the air duct in series, the pipe connected with the supporting component is sent into the second through hole of the support frame. After the lower pipe is connected to the upper pipe, there is no need to remove it, but it enters the decomposition tank together with the lower pipe, saving the disassembly step of the clamping component, and the time the pipe rotates with the overhead crane is less than the disassembly time of the pipe clamp, which saves time and has high air duct installation efficiency.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0029] The first embodiment of the present application provides a decomposition tank air duct connecting tool for connecting the first air duct and the second air duct in series. The connecting tool can quickly realize the serial connection of the first air duct and the second air duct, which is time-saving and efficient.

[0030] See also Figure 1 The decomposition tank 50 air duct connection tool provided in the embodiment of the present application includes a support frame 10, a clamping assembly 20 and a lifting mechanism (not shown in the figure), wherein: the support frame 10 is arranged at the top of the decomposition tank 50, and the top of the tank is provided with a first through-hole 51. The support frame 10 is provided with a second through-hole 11 for the first air duct 60 to extend into. The first through-hole 51 is connected to the second through-hole 11, so that the first air duct 60 passes through the second through-hole 11 and the first through-hole 51 in sequence and enters the decomposition tank 50;

[0031] The clamping assembly 20 is used to clamp the first air duct 60. During implementation, the clamping assembly 20 can be connected to the first air duct 60 in advance, and the clamping assembly 20 is placed on the support frame 10. The clamping assembly 20 and the support frame 10 are movably arranged so that the clamping assembly 20 can rotate relative to the support frame 10, thereby switching between the first position and the second position. When the clamping assembly 20 is in the first position, the clamping assembly 20 abuts against the top of the support frame 10 so that the first air duct 60 and the support frame 10 can be fixed to each other. When the clamping assembly 20 is in the second position, the projection of the clamping assembly 20 in the vertical direction falls within the first through hole 51 and the first through hole 51, so that the clamping assembly 20 and the first air duct 60 pass through the second through hole 11 and the first through hole 51 together.

[0032] A lifting mechanism, such as an overhead crane, is used to lift the first air duct 60 and the second air duct 70. When the lifting mechanism lifts the first air duct 60, it is convenient to pass the first air duct 60 through the second through hole 11 and the first through hole 51 in sequence. When the lifting mechanism lifts the second air duct 70, the second air duct 70 is aligned with the first air duct 60, which facilitates the connection of the first air duct 60 and the second air duct 70.

[0033] The support frame 10 is placed on the top of the decomposition tank 50 and is fixed by the weight of the first air duct 60 and the support frame 10 itself, making it easy to move. The space inside the decomposition tank 50 forms a space for accommodating the first air duct 60 and the second air duct 70. In the process of connecting the first air duct 60 and the second air duct 70 in series, the clamping assembly 20 is pre-connected to the first air duct 60, and the lower end of the first air duct 60 is sent into the decomposition tank 50 through the second through hole 11 of the support frame 10 and the first through hole 51 of the decomposition tank 50 by the lifting mechanism. Figure 2 , the clamping assembly 20 is set on the support frame 10 and is in the first position, thereby achieving stable support for the first air duct 60. Then the hoisting mechanism releases the first air duct 60 and hoists the second air duct 70, which can drive the second air duct 70 to adjust its position and posture so that the lower end of the second air duct 70 is connected to the upper end of the first air duct 60. At this time, the first air duct 60 and the second air duct 70 can be connected. After the two are connected, the hoisting mechanism rotates, and at the same time drives the clamping assembly 20, the first air duct 60 and the second air duct 70 to rotate relative to the support frame 10. Please refer to Figure 1 as well as Figure 3, so that the clamping assembly 20, the first air duct 60 and the second air duct 70 are rotated until the projection of the clamping assembly 20 in the vertical direction falls within the first through-hole 51 and the first through-hole 51, that is, the clamping assembly 20 is located in the second position, and then the lifting mechanism slowly moves downward, driving the second air duct 70, the first air duct 60 and the clamping assembly 20 to pass through the second through-hole 11 of the support frame 10 and the first through-hole 51 at the top of the decomposition tank 50, so as to fall into the interior of the decomposition tank 50 or the space below the platform of the decomposition tank 50, thereby quickly completing the series connection of the first air duct 60 and the second air duct 70.

[0034] Compared with the traditional method of fixing the lower pipe with a pipe clamp, connecting the upper pipe and the lower pipe and then loosening the pipe clamp, the present application can pre-fix the clamping assembly 20 with the lower pipe, and then send it into the second through hole 11 of the support frame 10. After the lower pipe is connected to the upper pipe, there is no need to remove it, but it enters the decomposition tank 50 together with the lower pipe, saving the disassembly step of the clamping assembly 20, saving time, and improving the efficiency of duct installation.

[0035] See also Figure 1 as well as Figure 2 The support frame 10 is provided with a limiting groove 12, which is connected to the second through-hole 11. When the clamping assembly 20 is in the first position, the clamping assembly 20 is at least partially located within the limiting groove 12. The groove wall of the limiting groove 12 can limit the clamping assembly 20, thereby improving the stability of the connection process between the first air duct 60 and the second air duct 70. When switching the clamping assembly 20 from the first position to the second position, the lifting mechanism must first lift the second air duct 70, thereby driving the first air duct 60 and the clamping assembly 20 to rise out of the limiting groove 12, and then rotate the second air duct 70 so that the vertical projection of the clamping assembly 20 falls into the first through-hole 51 and the second through-hole 11.

[0036] In some embodiments, the opening of the limiting groove 12 may be trumpet-shaped with the large opening facing upward, so that the clamping assembly 20 can easily enter the limiting groove 12 during the process of the lifting mechanism lifting the first air duct 60, further improving the installation efficiency.

[0037] The limiting groove 12 can match the shape of the clamping assembly 20 to limit the clamping assembly 20 and improve the stability during the connection process of the first air duct 60 and the second air duct 70. In some embodiments, the limiting groove 12 can be a rectangular groove or a limiting groove 12 that is larger in the middle and smaller at both ends.

[0038] In some embodiments, see Figure 2The second through hole 11 can be a rectangular hole or an elliptical hole. In the case where the second through hole 11 is a rectangular hole, the size of the clamping assembly 20 along its own length direction is larger than the wide side size of the rectangular hole, so that when the clamping assembly 20 is in the first position, the top of the support frame 10 abuts against the clamping assembly 20 to stably support the clamping assembly 20 and the first air duct 60. The size of the clamping assembly 20 along its own width direction is smaller than the short side size of the rectangular hole, so that when the clamping assembly 20 is in the second position, the clamping assembly 20, the first air duct 60 and the second air duct 70 can move down into the decomposition tank 50 through the rectangular hole.

[0039] In some embodiments, the long side of the rectangular groove and the long side of the rectangular hole are perpendicular to each other. In other embodiments, the angle between the long side of the rectangular groove and the long side of the rectangular hole can also be 80°, 70° or 60°, etc., which can achieve stable support of the support frame 10 and the clamping assembly 20 and move downward into the decomposition trough 50.

[0040] In some embodiments, the number of clamping assemblies 20 is the same as the number of air ducts. For example, if there are four air ducts, four clamping assemblies 20 are also provided. Each clamping assembly 20 is pre-connected to the corresponding air duct so as to be directly hoisted and used during the connection process.

[0041] In some embodiments, see Figure 3 The clamping assembly 20 includes a clamping plate 21 and a threaded member 22. Two clamping plates 21 and two threaded members 22 are provided. The two clamping plates 21 are connected by the threaded member 22. The two threaded members 22 and the two clamping plates 21 enclose a clamping cavity for clamping the first air duct 60. When the two threaded members 22 are tightened, the two clamping plates 21 can be moved closer to each other to clamp the first air duct 60. When the two threaded members 22 are loosened, the two clamping plates 21 can be moved away from each other to release the first air duct 60. In other embodiments, the two clamping plates 21 of the clamping assembly 20 are hinged at one end and connected at the other end by the threaded member 22, which can also achieve clamping and loosening of the first air duct 60.

[0042] The splint 21 can be cut from a 304 stainless steel plate with a thickness of 10 mm. The splint 21 is provided with a mounting hole with a diameter of 16 mm. The screw 22 passes through the mounting hole to achieve the connection between the two splints 21, and the splints 21 can be reused.

[0043] In some embodiments, see Figure 2 The splint 21 includes a connecting section 211 and a clamping section 212. There are two connecting sections 211, and the clamping section 212 is located between the two connecting sections 211. The connecting sections 211 of the two splints 21 are connected by a screw 22. The inner side surface of the clamping section 212 is an arc surface that matches the shape of the first air duct 60 to increase the effective area between the splint 21 and the first air duct 60, thereby improving the connection stability of the clamping assembly 20 and the first air duct 60.

[0044] In some embodiments, the connecting section 211 of the clamping plate 21 extends along the length of the clamping assembly 20, and the screw member 22 extends along the width of the clamping assembly 20 to save space. In other embodiments, the clamping plate 21 can extend along the width of the clamping assembly 20, and the screw member 22 can extend along the length of the clamping assembly 20.

[0045] In some embodiments, see Figure 1 The ends of the first and second air ducts 60 and 70 are each provided with flanges 61 and 71, which are screwed together. The flanges 61 and 71 can be pre-attached to the pipes. The bolted connection between the first and second air ducts 60 and 70 reduces the requirements for docking accuracy compared to welding, thereby improving air duct installation efficiency. In other embodiments, the first and second air ducts 60 and 70 can also be welded, allowing for the serial connection of two adjacent air ducts.

[0046] When the first air duct 60 and the second air duct 70 are bolted together by the flanges 61 and 71, the clamping assembly 20 is located below the flange 61 of the first air duct 60. Even if the threaded member 22 of the clamping assembly 20 becomes loose, the flange 61 abuts against the top of the clamping assembly 20. Therefore, the first air duct 60 is still fixed to the upper part of the support frame 10 by the support of the flange 61 by the clamping plate 21, preventing the first air duct 60 from falling.

[0047] In some embodiments, the bottom of the support frame 10 is provided with anti-slip grooves to increase the friction between the support frame 10 and the top of the decomposition tank 50, thereby ensuring the relative position stability between the support frame 10 and the decomposition tank 50. In other embodiments, a first clamping structure can be provided on the support frame 10, and the top of the decomposition tank 50 is provided with a second clamping structure that cooperates with the first clamping structure. The first clamping structure and the second clamping structure are clamped together, so that the support frame 10 is connected to the top of the decomposition tank 50, thereby improving the connection stability between the two.

[0048] The working process of the decomposition tank 50 air duct connection tool provided in the embodiment of the present application is as follows:

[0049] The clamping assembly 20 is pre-connected to the first air duct 60. If the decomposition tank 50 requires an air duct installation, the support frame 10 is placed on the top of the decomposition tank 50 so that the second through hole 11 of the support frame 10 is connected to the first through hole 51 of the top. The hoisting mechanism is hoisted to the upper end of the first air duct 60 and then drives the first air duct 60 to move so that the lower end of the first air duct 60 passes through the second through hole 11 of the support frame 10 and the first through hole 51 of the decomposition tank 50 and is delivered into the decomposition tank 50. The clamping assembly 20 is located in the limiting groove 12 of the support frame 10 and is in the first position, thereby achieving stable support for the first air duct 60. The hoisting mechanism then releases the first air duct 60 and hoists the second air duct 70, which can drive the second air duct 70 to adjust its position and posture so that the lower end of the second air duct 70 is connected to the upper end of the first air duct 60. At this time, the first air duct 60 and the second air duct 70 can be connected by bolts.

[0050] After the connection between the first air duct 60 and the second air duct 70 is completed, the lifting mechanism first lifts so that the clamping assembly 20 leaves the limit slot 12, and then rotates to drive the clamping assembly 20, the first air duct 60 and the second air duct 70 to rotate relative to the support frame 10, so that the clamping assembly 20 is located in the second position, and then the lifting mechanism slowly moves the second air duct 70 downward, and the lower ends of the first air duct 60, the clamping assembly 20 and the second air duct 70 pass through the second through hole 11 of the support frame 10 and the first through hole 51 at the top of the decomposition tank 50 to fall into the interior of the decomposition tank 50 or the space below the platform of the decomposition tank 50, thereby quickly completing the series connection of the first air duct 60 and the second air duct 70.

[0051] Repeat the above steps to connect multiple air ducts in series.

[0052] After all the air ducts are connected in series, the top air duct can be connected to the compressed air main pipeline branch valve at the top of the decomposition tank 50 through a flange hose, and compressed air is introduced to stir the materials in the decomposition tank 50.

[0053] The decomposition tank 50 air duct connection tool provided in this application has at least the following advantages:

[0054] (1) By rotatably arranging the clamping assembly 20 relative to the support frame 10, the first air duct 60 can be quickly moved downward and fixed, shortening the connection and installation time of the air duct. This prevents the material from rapidly settling due to lack of stirring in the decomposition tank 50 in the event of a stirring failure, reduces cleaning costs, and ensures that the aluminum hydroxide decomposition index is controllable. In practical applications, the installation time of the compressed air duct of the decomposition tank 50 can be shortened from 4 hours to 1 hour.

[0055] (2) Since the installation of air ducts does not require temporary electric welding operations, the occurrence of two dangerous operations, fire operations and temporary use of electricity, is reduced, which greatly reduces the safety risks of construction operations in emergency situations.

[0056] (3) The support frame 10 provided in the present application is placed on the top of the decomposition tank 50 and is fixed by the weight of the first air duct 60 and the support frame 10 itself. It is easy to move and can be quickly deployed and used from the top of different decomposition tanks 50, achieving the effect of multiple uses of one thing.

[0057] (4) Weld flanges of the same specifications at both ends of the air duct in advance and connect the clamping assembly 20. Place the prepared air duct in an easily accessible position on the top of the decomposition tank 50. Prepare the bolts, flange connection washers, and wrenches required for flange connection in the tool box on the top of the tank for quick use in emergency situations, reducing the time required to prepare materials.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
