Description

Technical Field

[0001] This utility model relates to the field of three-saddle supports, specifically to a three-saddle support for heavy-duty reactor equipment. Background Technology

[0002] This saddle is primarily used in the hydrometallurgical industry to support and secure heavy-duty reactor equipment. It evenly distributes the equipment's weight onto the foundation or transport vehicle, ensuring stability and safety during operation and transportation. It is typically welded from a saddle-shaped pad, web plate, stiffening plates, and a base plate. The pad contacts the equipment cylinder, improving localized stress distribution. The web and stiffening plates connect and reinforce the equipment, transferring the load from the pad to the base plate and enhancing the overall rigidity of the saddle. The base plate connects to the foundation using anchor bolts, although anchor bolts are not required during shipping or transport. Depending on the needs, annular reinforcing rings may be added at or near the support section to increase the circumferential rigidity and strength of the cylinder. Furthermore, saddles are divided into fixed and movable types, differing in the bolt holes on the base plate: fixed saddles have circular bolt holes, while movable saddles have oblong bolt holes. The weight of the equipment is transferred from the cylinder to the pad of the saddle, then through the web and stiffening plates to the base plate, and finally distributed onto the foundation. For equipment subject to temperature changes, a fixed saddle provides a stable support point, while a movable saddle allows the equipment to expand and contract freely along the axial direction during thermal expansion and contraction, avoiding additional stress on the equipment and ensuring the structural safety of the equipment and the saddle.

[0003] This equipment is heavy and has a long axis. The thermal expansion and contraction of the equipment due to ambient temperature causes significant damage to the foundation and pipelines. Therefore, a special three-saddle structure is required for support. Furthermore, when the stirring motor inside the reactor is working, it generates a large shear force. Ordinary fixed saddles cannot be firmly anchored to the foundation, which leads to movement and deformation between the saddles and the foundation, ultimately requiring the reactor to be repositioned and reinstalled.

[0004] Therefore, it is necessary to design a three-saddle support for heavy-duty reactor equipment, which can reduce the movement and deformation between the saddle support and the foundation. At the same time, it is also necessary to ensure that the axial thermal expansion and contraction that occurs when the reactor temperature changes can be resolved. Utility Model Content

[0005] The purpose of this invention is to provide a three-saddle support for heavy-duty reactor equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A three-saddle support for a heavy-duty reactor is provided, comprising a fixed saddle and two sliding saddles located on both sides of the fixed saddle. The fixed saddle includes a support first fixedly connected to the reactor, and a shear key first embedded in a concrete foundation is fixedly provided at the bottom of the support base plate first. The sliding saddle includes a lower slide plate partially embedded in the concrete foundation, and a shear key second embedded in the concrete foundation is fixedly provided at the bottom of the lower slide plate.

[0008] Furthermore, the bottom of the shear key is provided with multiple fixing stiffeners that are fixedly connected to the shear key.

[0009] Furthermore, the bottom of the second shear key is provided with multiple horizontal columns that are fixedly connected to the second shear key.

[0010] Furthermore, the fixed saddle includes a support that is fixedly connected to the reactor. The second support base plate is fitted with the top of the lower slide plate. The second support base plate is fixedly connected to the lower slide plate by a bolt. The bottom of the bolt is fixedly connected to the concrete foundation. The second support base plate has a waist-shaped hole along the length of the reactor.

[0011] Furthermore, a fiberglass sliding pad is provided on the upper surface of the sliding plate.

[0012] Furthermore, the support base plate is fixedly connected to the concrete foundation by bolts.

[0013] Furthermore, a base plate is fixedly installed at the bottom of bolt one, and a reinforcing rib is fixedly installed between the base plate and bolt one.

[0014] The beneficial effects of this utility model are as follows: This heavy-duty reactor equipment uses a three-saddle base, and by setting shear keys one and two, the movement and deformation between the saddle base and the foundation can be reduced. At the same time, the second support base plate can slide horizontally on the sliding plate, allowing the reactor to move horizontally when it undergoes thermal expansion and contraction, thus solving the problem of axial thermal expansion and contraction.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0023] Reference Figures 1 to 4 The diagram illustrates a three-saddle support for a heavy-duty reactor, comprising a fixed saddle 2 and two sliding saddles 3 located on either side of the fixed saddle 2. The fixed saddle 2 includes a support 1 fixedly connected to the reactor 1, with a shear key 2b embedded in a concrete foundation 6 fixedly installed at the bottom of the support base plate 2a. The sliding saddles 3 include a sliding plate 3a partially embedded in the concrete foundation 6, with a shear key 3b embedded in the concrete foundation 6 fixedly installed at the bottom of the sliding plate 3a. When the stirring motor inside the reactor operates, generating significant shear forces, the shear key 2b and shear key 3b reduce the movement and deformation between the saddle and the foundation.

[0024] The bottom of the shear key 2b is provided with multiple fixing plates 2c that are fixedly connected to the shear key 2b. By providing multiple fixing plates 2c, the connection force between the shear key 2b and the concrete foundation 6 is improved.

[0025] The bottom of shear key 2 3b is provided with multiple horizontal columns 3c that are fixedly connected to shear key 2 3b. By providing multiple horizontal columns 3c, the connection force between the concrete foundation 6 of shear key 2 3b is improved.

[0026] The fixed saddle 2 includes a support fixedly connected to the reactor 1. The support base plate 3d is fitted to the top of the lower slide plate 3a. The support base plate 3d is fixedly connected to the lower slide plate 3a by bolt 4. The bottom of bolt 4 is fixedly connected to the concrete foundation 6. The support base plate 3d has an oblong hole 3d1 along the length of the reactor 1. When the reactor 1 undergoes thermal expansion and contraction, its deformation in the width direction is small, while its deformation in the length direction is large. When deformation occurs, it will cause the support base plate 3d to move horizontally, allowing it to slide horizontally on the lower slide plate 3a. The oblong hole 3d1 ensures that the support base plate 3d can move.

[0027] A glass fiber sliding pad is provided on the upper surface of the sliding plate 3a. The glass fiber sliding pad reduces the friction of the support base plate 3d along the axis of the reactor 1, making its sliding smoother. The glass fiber sliding pad is filled with more than 25% glass fiber.

[0028] The support base plate 2a is fixedly connected to the concrete foundation 6 by bolt 5. Bolt 5 passes through the support base plate 2a and is fixedly connected to the concrete foundation 6. A nut is provided at the top of bolt 5. When installing the reactor, it is removed and bolt 5, which is pre-embedded in the concrete foundation 6, is used for positioning.

[0029] A base plate 4a is fixedly installed at the bottom of bolt 4, and a reinforcing rib is fixedly installed between the base plate 4a and bolt 4. By welding the base plate 4a and the reinforcing rib to bolt 4, the connection between the bottom of bolt 4 and the concrete foundation 6 is improved, ensuring the stability between the base plate 4a and the concrete foundation 6.

[0030] This heavy-duty reactor equipment uses a three-saddle system. By incorporating shear keys one and two, it can reduce movement and deformation between the saddle and the foundation. Simultaneously, the second support base plate allows for horizontal sliding on the sliding plate, enabling horizontal movement of the reactor during thermal expansion and contraction, thus mitigating axial thermal expansion and contraction.

[0031] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
