Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to a quick-release centrifugal extractor and its frame. Background Technology

[0002] A centrifugal extractor is a liquid-liquid extraction device where the liquid mixture undergoes mixing, mass transfer, and centrifugal separation under the action of the rotating components. The centrifugal extractor mainly consists of a motor, rotating components, and a casing. The rotating component is the drum. The centrifugal extractor utilizes the powerful centrifugal force generated by the high-speed rotation of the drum to rapidly mix and separate two immiscible liquids with different densities, achieving efficient extraction.

[0003] Existing centrifugal extractors typically feature a frame to form the mounting base for their various components. For example, a centrifugal extractor disclosed in Chinese Utility Model Patent No. CN206715363U includes a frame, motor, flange, housing, and drum. The flange and housing together form the outer shell, with the flange covering the upper part of the shell and enclosing its inner cavity. The upper part of the inner cavity has a heavy phase weir and a light phase weir, forming a heavy phase collection chamber and a light phase collection chamber respectively. The upper part of the housing has a heavy phase outlet corresponding to the heavy phase collection chamber and a light phase outlet corresponding to the light phase collection chamber. The lower part of the housing has a heavy phase inlet and a light phase inlet. A motor is mounted on the upper side of the flange, constituting the drive device. The motor's output shaft is connected to a transmission shaft, which passes through the flange and connects to the drum. The drum is installed inside the housing, and the motor drives the drum to rotate via the transmission shaft to perform the separation process.

[0004] The motor, drum, and outer shell of the aforementioned centrifugal extractor are assembled together to form the main body of the centrifugal extractor. The heavy phase outlet and light phase outlet serve as discharge ports located on the upper part of the outer shell, while the heavy phase inlet and light phase inlet serve as feed ports located on the lower part of the outer shell. To facilitate discharge, a large-volume liquid collection chamber is provided on the upper part of the outer shell corresponding to the discharge port, resulting in an upper diameter larger than the lower diameter and a downward-facing step at the junction of the upper and lower parts of the outer shell. The flange diameter is slightly larger than the upper diameter of the shell, allowing the outer edge of the flange to form a flange edge for fixing to the frame. The flange is fixed to the frame with bolts. The frame typically includes several support columns and mounting bases fixed to the upper ends of the support columns. The mounting base is a plate-like structure with a central mounting hole for the centrifugal extractor body to pass through. The outer diameter of the upper part of the centrifugal extractor shell matches the central mounting hole. The circumferential edge of the central mounting hole has a notch to avoid the discharge port area. The outer edge of the flange is supported on the upper side of the mounting base and fixed with bolts. The part of the centrifugal extractor below the flange is suspended in the space between the various support columns below the mounting base.

[0005] Currently, the centrifugal extractor is installed by hoisting the main body onto the frame. During hoisting, the crane lifts the main body to the position corresponding to the center mounting hole of the mounting base on the lower frame. Then, the main body is lowered so that it extends through the center mounting hole under the mounting base, with its flange firmly supported on the base. Finally, bolts are tightened to secure the connection. While this installation method provides sufficient height above the frame for hoisting, in some installation scenarios, such as installing large equipment or moving skid-mounted units, the installation height may be insufficient or the skid space may be limited, leading to difficulties in installing the centrifugal extractor onto the frame. Utility Model Content

[0006] The purpose of this utility model is to provide a quick-release centrifugal extractor frame to solve the problems of insufficient installation space height or limited skid-mounting space, as well as how to improve the convenience and efficiency of installing the centrifugal extractor and frame; the purpose of this utility model is also to provide a quick-release centrifugal extractor to solve the above problems.

[0007] The technical solution for the frame of the quick-release centrifugal extractor of this utility model is as follows:

[0008] A frame for a quick-release centrifugal extractor is provided. The top of the frame is provided with a mounting base. The mounting base is provided with a fixing structure for fixing the body of the centrifugal extractor. The frame has an open space located below the mounting base. The open space allows the body of the centrifugal extractor to extend into it and is open to the horizontal side. The mounting base is provided with a vertically penetrating mounting groove with its opening facing the horizontal side, so that the body of the centrifugal extractor can be inserted from the horizontal side of the frame into the mounting groove and the open space below the mounting groove and supported on the mounting base.

[0009] Beneficial effects: This utility model modifies the frame of the existing centrifugal extractor by changing the structure on the mounting base of the frame that avoids the main body. The structure is changed to a mounting groove facing the horizontal side. The mounting groove is connected to the open space below the mounting base in the frame. Both the opening of the mounting groove and the open space below the mounting groove face the horizontal side. This allows the main body of the centrifugal extractor to be installed into the mounting groove and the space below the mounting groove from the horizontal side and then supported on the mounting base. In this way, when the main body of the centrifugal extractor is installed on the frame, the height of the centrifugal extractor does not need to exceed the height of the entire frame, which can reduce the space height required for installation. The main body of the centrifugal extractor is installed on the frame from the side, without being limited by installation height or skid space. It also improves the convenience of installing the main body of the centrifugal extractor on the frame and can quickly fix the main body of the centrifugal extractor to the frame. The main body of the centrifugal extractor and the frame can be quickly installed in the centrifugal extractor production plant or at the centrifugal extractor use site. Correspondingly, the centrifugal extractor body and frame can be quickly disassembled, making it flexible to use and easy to maintain.

[0010] Furthermore, the mounting groove includes a bottom surface and two opposite side surfaces spaced apart along the width of the groove. The side surfaces are flat, and the bottom surface is an arc surface for adapting to the outer peripheral surface of the centrifugal extractor.

[0011] Furthermore, the mounting base has a fixed support portion located at the edge of the upper opening of the mounting groove. The fixed support portion is used to support the downward stepped surface of the centrifugal extractor body located below its discharge port. The fixing structure is provided on the fixed support portion.

[0012] Furthermore, the depth of the mounting groove is not less than the outer diameter of the portion of the centrifugal extractor body located below the downward-facing step surface.

[0013] Furthermore, the groove opening is provided with a connector that connects the two sides of the groove opening, and the connector is detachably connected to the mounting base.

[0014] Furthermore, the connector is provided with a portion for supporting the body of the centrifugal extractor.

[0015] Furthermore, the frame has two or more mounting positions arranged side by side, each mounting position including a mounting slot and a corresponding open space below the mounting slot, so that two or more centrifugal extractor bodies can be installed on the same frame. The advantage is that it achieves integration; multiple centrifugal extractor bodies can be integrated and installed on the same frame, resulting in high installation efficiency, saving time and labor, and reducing costs.

[0016] Furthermore, the frame is provided with a first mounting position and a second mounting position. Both the first mounting position and the second mounting position include a mounting groove and a corresponding open space below the mounting groove. The groove opening of the mounting groove of the first mounting position is arranged opposite to the groove opening of the mounting groove of the second mounting position. Both the first mounting position and the second mounting position are used to install the body of the centrifugal extractor.

[0017] Furthermore, the frame includes an upper mounting plate and two opposing upright plates. The upper mounting plate constitutes the mounting base and is fixed to the upper ends of the two upright plates. The two upright plates are spaced apart and opposite each other along the width of the mounting groove, and an open space is formed between the two upright plates located below the mounting groove.

[0018] The technical solution of this utility model's quick-release centrifugal extractor is as follows:

[0019] A quick-release centrifugal extractor includes a centrifugal extractor body and a centrifugal extractor frame. The centrifugal extractor body includes a housing, a rotating component installed inside the housing, and a drive device for rotating the rotating component. The top of the centrifugal extractor frame is provided with a mounting base. The mounting base is provided with a fixing structure for fixing the centrifugal extractor body. The frame has an open space located below the mounting base. The open space allows the centrifugal extractor body to extend into and is open to the horizontal side. The mounting base is provided with a vertically penetrating mounting groove with its opening facing the horizontal side, so that the centrifugal extractor body can be inserted from the horizontal side of the frame into the mounting groove and the open space below the mounting groove and supported on the mounting base.

[0020] Beneficial effects: This utility model modifies the frame of the existing centrifugal extractor by changing the structure on the mounting base of the frame that avoids the main body. The structure is changed to a mounting groove facing the horizontal side. The mounting groove is connected to the open space below the mounting base in the frame. Both the opening of the mounting groove and the open space below the mounting groove face the horizontal side. This allows the main body of the centrifugal extractor to be installed into the mounting groove and the space below the mounting groove from the horizontal side and then supported on the mounting base. In this way, when the main body of the centrifugal extractor is installed on the frame, the height at which the main body of the centrifugal extractor is lifted does not need to exceed the height of the entire frame, which can reduce the space height required for installation. The main body of the centrifugal extractor is installed on the frame from the side, which is not easily affected by the installation height limitation and thus the installation convenience is not affected.

[0021] Furthermore, the mounting groove includes a bottom surface and two opposite side surfaces spaced apart along the width of the groove. The side surfaces are flat, and the bottom surface is an arc surface for adapting to the outer peripheral surface of the centrifugal extractor.

[0022] Furthermore, the mounting base has a fixed support portion located at the edge of the upper opening of the mounting groove. The fixed support portion is used to support the downward stepped surface of the centrifugal extractor body located below its discharge port. The fixing structure is provided on the fixed support portion.

[0023] Furthermore, the depth of the mounting groove is not less than the outer diameter of the portion of the centrifugal extractor body located below the downward-facing step surface.

[0024] Furthermore, the groove opening is provided with a connector that connects the two sides of the groove opening, and the connector is detachably connected to the mounting base.

[0025] Furthermore, the connector is provided with a portion for supporting the body of the centrifugal extractor.

[0026] Furthermore, the frame has two or more mounting positions arranged side by side, each mounting position including a mounting slot and a corresponding open space below the mounting slot so that the bodies of two or more centrifugal extractors can be mounted on the same frame.

[0027] Furthermore, the frame is provided with a first mounting position and a second mounting position. Both the first mounting position and the second mounting position include a mounting groove and a corresponding open space below the mounting groove. The groove opening of the mounting groove of the first mounting position is arranged opposite to the groove opening of the mounting groove of the second mounting position. Both the first mounting position and the second mounting position are used to install the body of the centrifugal extractor.

[0028] Furthermore, the frame includes an upper mounting plate and two opposing upright plates. The upper mounting plate constitutes the mounting base and is fixed to the upper ends of the two upright plates. The two upright plates are spaced apart and opposite each other along the width of the mounting groove, and an open space is formed between the two upright plates located below the mounting groove.

[0029] Furthermore, the outer shell of the centrifugal extractor body includes an upper shell and a lower shell, and one of the outer side walls of the upper shell and the lower shell is provided with an extension in the horizontal direction, and the extension is fixedly connected to the mounting base.

Detailed Implementation

[0039] The basic concept of this centrifugal extractor is to use an open slot to allow the centrifugal extractor body to be mounted on the frame from the horizontal side of the frame, thereby reducing the space height required for the installation of the centrifugal extractor body and facilitating hoisting operations in spaces with limited height.

[0040] The present invention will be described in detail below with reference to specific embodiments.

[0041] Example 1 of the quick-release centrifugal extractor of this utility model:

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the centrifugal extractor includes a main body and a frame 200. The main body is the centrifugal extractor body 100, which is fixedly mounted on the frame 200. The centrifugal extractor is used by being fixed by the frame 200.

[0043] The centrifugal extractor body 100 includes a shell, a rotating component installed inside the shell, and a drive device for driving the rotating component to rotate. The drive device includes a motor 105, the rotating component includes a drum, and the drive device is installed on the top of the shell. The shell includes a cover plate and a main shell. The cover plate and the main shell together form an inner cavity of the shell. The rotating component is installed in the inner cavity of the shell. The rotating shaft of the rotating component is connected to the output shaft of the motor 105. The drive device is installed on the upper side of the cover plate. The shell is generally cylindrical. The motor 105 is coaxially arranged with the shell, and the axis is along the vertical direction. The shell includes an upper shell part 102 and a lower shell part 103 coaxially arranged. The outer diameter of the upper shell part 102 is larger than the outer diameter of the lower shell part 103. A downward stepped surface 104 is formed at the junction of the upper shell part 102 and the lower shell part 103. The downward stepped surface 104 is an annular surface. The upper part 102 of the outer casing is provided with a heavy phase liquid collection chamber and a light phase liquid collection chamber. The upper part 102 of the outer casing has an outward-facing discharge port 101, which is connected to the corresponding liquid collection chamber. The lower part 103 of the outer casing is provided with a feed port. The downward-facing stepped surface 104 is the stepped surface adjacent to the discharge port 101. The frame 200 provides a base for suspending and fixing the main body. The specific structure and working principle of the main body 100 of the centrifugal extractor can be found in the prior art, and will not be described in detail here.

[0044] The frame 200 of the centrifugal extractor has a certain height to accommodate its main body. A mounting base 1 is located at the top of the frame 200, and the mounting base 1 has a fixing structure for securing the main body 100 of the centrifugal extractor. An open space is provided within the frame 200 below the mounting base 1, allowing the main body 100 of the centrifugal extractor to extend into it and opening towards the horizontal side. The mounting base 1 has a vertically extending mounting groove 11 with its opening facing the horizontal side. The main body 100 of the centrifugal extractor can be inserted into the mounting groove 11 and the open space below the mounting groove 11 from the horizontal side of the frame 200 and supported on the mounting base 1. Thus, when installing the main body 100 of the centrifugal extractor onto the frame 200, the height at which the main body 100 is lifted does not need to exceed the entire height of the frame 200, reducing the required installation height. Furthermore, the main body 100 of the centrifugal extractor is installed onto the frame 200 from the side, minimizing installation space height limitations and ensuring ease of installation.

[0045] In this embodiment, the frame 200 of the centrifugal extractor corresponds one-to-one with the main body. The frame 200 is provided with a mounting position, which includes a mounting groove 11 and an open space below the mounting groove 11. The open space below the mounting groove 11 is the open space below the mounting seat 1 in the frame 200. The mounting groove 11 and the open space below the mounting groove 11 allow the main body 100 of the centrifugal extractor to be inserted from the side, and then the main body 100 of the centrifugal extractor is fixed to the frame 200 by the fixing structure on the mounting seat 1.

[0046] The mounting groove 11 is generally U-shaped. It includes a bottom surface and two opposing side surfaces spaced apart along its width. The side surfaces are flat, and the two side surfaces are parallel and opposite to each other. The bottom surface is an arc surface designed to fit the outer circumference of the centrifugal extractor body 100. In this embodiment, the opening of the mounting groove 11 faces forward, and the two side surfaces are opposite each other horizontally. After the centrifugal extractor body 100 is inserted into the mounting groove 11, it fits snugly against the bottom surface of the groove, increasing the support area and ensuring reliable installation. The two opposing side surfaces of the mounting groove 11 guide the centrifugal extractor body 100 into place. In other embodiments, the bottom surface of the mounting groove can also be a flat surface extending linearly in the left-right direction, perpendicular to the side surfaces. The two side surfaces and the bottom surface provide three-point support to the centrifugal extractor body in the circumferential direction.

[0047] The mounting groove 11 faces forward. Since the mounting groove 11 is vertically continuous, it has openings on both the upper and lower sides. The mounting base 1 has a fixed support at the edge of the upper opening of the mounting groove 11. The fixed support is used to support the downward stepped surface 104 of the centrifugal extractor body 100. After the centrifugal extractor body 100 is installed on the frame 200, the downward stepped surface 104 abuts against the upper side of the mounting base 1. The downward stepped surface 104 provides support and fixation, so that the upper part 102 of the outer shell with a larger outer diameter is located above the mounting base 1. The frame 200 provides fixed support for the body below the downward stepped surface 104. The lower part 103 of the outer shell has a smaller outer diameter. The mounting groove 11 only needs to avoid the part of the body with a smaller outer diameter below the feed inlet. It does not need to avoid the upper part 102 of the outer shell with a larger outer diameter. This can reduce the size of the mounting groove 11, thereby reducing the size of the mounting base 1, and thus reducing the size of the frame 200, saving floor space. In other embodiments, the outer diameter of the cover plate of the centrifugal extractor body can be made larger, the width of the mounting groove can be made wider, and the size of the mounting groove can be adapted to the outer diameter of the upper part of the outer shell where the feed port is located, so that the mounting base supports the outer edge of the cover plate and is fixedly connected.

[0048] In this embodiment, the upper side of the mounting groove 11, which is the fixed support part of the main body 100 of the centrifugal extractor, surrounds the upper opening of the mounting groove 11. The fixed support part is provided with bolt holes and forms a fixing structure. Correspondingly, the downward stepped surface 104 is provided with threaded holes. The bolt holes on the mounting base 1 correspond one-to-one with the threaded holes on the downward stepped surface 104 for fixed connection by bolts. In other embodiments, studs can also be provided on the downward stepped surface. The fixing structure can be a through hole for the stud to pass through, so that the frame and the main body can be fixedly connected by nuts engaging with the studs below the mounting base.

[0049] The dimensions of the mounting base 1 in both the left-right and front-back directions are greater than or equal to the outer diameter of the lower part 103 of the outer shell to ensure sufficient support area. The lower part 103 of the outer shell is the portion of the centrifugal extractor body 100 located below the downward-facing stepped surface 104. The width of the mounting groove 11 is adapted to the outer diameter of the lower part 103 of the outer shell, and the depth of the mounting groove 11 is greater than or equal to the outer diameter of the lower part 103 of the outer shell, so that the centrifugal extractor body 100 can be fixedly installed at the center of the frame 200, which is beneficial to reliable installation. In other embodiments, the depth of the mounting groove may be slightly smaller than the outer diameter of the lower part of the outer shell.

[0050] To strengthen the structure at the mounting slot 11, a connector is provided at the opening of the mounting slot 11 to connect the left and right edges of the opening. This connector is not shown in the figure and can be a connecting plate extending in the left-right direction. Both ends of the connecting plate have fixing holes for bolting to the mounting base 1. The connecting plate is fixed to the lower side of the mounting base 1, which improves the strength of the frame 200. The connector is detachably connected to the mounting base 1 by bolts. Before installing the centrifugal extractor body 100, the connector is not connected to the mounting base 1. After the centrifugal extractor body 100 is installed, the connector is then installed without affecting the side installation operation of the centrifugal extractor body 100. The connecting plate has a part for supporting the centrifugal extractor body 100. The middle of the connecting plate arches upward and is flush with the upper side of the mounting base 1, so that the connector provides support for the centrifugal extractor body 100, which is beneficial for reliable support. In other embodiments, the connecting plate may not be provided, or a round rod may be used as the connector; the connector may also be a flat plate, without the part supporting the centrifugal extractor body.

[0051] The frame 200 includes an upper mounting plate and two opposing upright plates 2. The upper mounting plate forms a mounting base 1 and is fixed to the upper ends of the two upright plates 2. The two upright plates 2 are positioned opposite each other, that is, they are spaced apart along the width of the mounting groove 11. An open space is formed between the two upright plates 2 below the mounting groove 11. The structure is simple and easy to manufacture. In other embodiments, support columns can be fixed at the four corners of the mounting base, and the four support columns can form a space below the mounting base.

[0052] The space between the two upright plates 2 is open from front to back, allowing the open space to open horizontally to both sides, which are the front and rear sides. Both the front and rear sides are horizontal sides of the frame. The lower ends of the two upright plates 2 are fixedly connected by a lower crossbeam 3 for reinforcement. Above the lower crossbeam 3 is the mounting space for the centrifugal extractor body 100. The upright plates 2 are perpendicularly connected to the upper mounting plate and can be fixed by welding. The centrifugal extractor body 100 can be installed into the frame 200 from the front side and suspended on the top of the frame 200. In other embodiments, if the size allows, only the open space can be open to the front side, while the rear side is sealed with a rear panel. The mounting groove 11 and the open space below the mounting groove should be open in the same direction.

[0053] When installing the centrifugal extractor body 100, the height at which the centrifugal extractor body 100 is lifted does not need to exceed the height of the entire frame 200. Instead, it can be directly moved into the frame 200 from the front, so that the centrifugal extractor body 100 is supported on the mounting base 1 of the frame 200. Then, bolts are passed through the bolt holes of the mounting base 1 and the bolt holes on the centrifugal extractor body 100 to fix the centrifugal extractor body 100 to the frame 200.

[0054] The components of the centrifugal extractor are pre-assembled as a whole. The centrifugal extractor body and frame can be installed at the manufacturer's factory and then transported to the site of use as a complete unit. Alternatively, the centrifugal extractor body and frame can be installed together at the site of use.

[0055] Example 2 of the quick-release centrifugal extractor of this utility model:

[0056] The difference between this embodiment and Embodiment 1 above is that, in this embodiment, the frame of the centrifugal extractor is equipped with multiple centrifugal extractor bodies, such as... Figure 4 and Figure 5 As shown, the frame 200 has three mounting positions arranged side by side. Each mounting position includes a mounting slot and a corresponding open space below the mounting slot, allowing three centrifugal extractor bodies 100 to be mounted on the same frame 200. Adjacent mounting positions share a vertical plate, and all mounting positions share a mounting base, meaning all mounting slots are located on the same mounting base 1. The number of mounting positions can be flexibly selected according to the actual usage scenario. Integrating multiple centrifugal extractor bodies 100 on one frame 200 can save space, improve space utilization, and facilitate installation. In other embodiments, the frame can also have two or more mounting positions.

[0057] Example 3 of the quick-release centrifugal extractor of this utility model:

[0058] The difference between this embodiment and Embodiment 1 is that in this embodiment, the centrifugal extractor frame is equipped with multiple centrifugal extractor bodies arranged in two rows, as shown below. Figure 6 and Figure 7 As shown, the frame 200 is provided with a first mounting position and a second mounting position. Each mounting position includes a mounting slot and a corresponding open space below the mounting slot. The openings of the mounting slots in the first and second mounting positions are opposite to each other. Both the first and second mounting positions are used to mount the centrifugal extractor body 100. The mounting slots of the first and second mounting positions are both located on the same mounting base. The space between two adjacent upright plates of the frame 200 forms a mounting space for one first mounting position and one second mounting position. The mounting space includes the space inside the mounting slot and the corresponding open space below the mounting slot. The openings of the mounting slots in the first and second mounting positions face the front and rear sides respectively, allowing each centrifugal extractor body 100 to be installed into its corresponding mounting position from the front and rear sides of the frame 200. Multiple first and second mounting positions are provided, arranged in a row for the first and second mounting positions, allowing for the arrangement of two rows of centrifugal extractor bodies 100. The number of installation positions can be flexibly selected according to the actual use scenario. Two rows of centrifugal extractor bodies 100 can be integrated on a single rack 200, which can save space, improve space utilization, and is easy to install.

[0059] Example 4 of the quick-release centrifugal extractor of this utility model:

[0060] The difference between this embodiment and Embodiment 1 is that the centrifugal extractor body 100 includes an upper outer shell 102 and a lower outer shell 103. The outer side wall of the upper outer shell 102 has an extension in the horizontal direction, and the extension is fixedly connected to the mounting base 1. It should be noted that the closer the extension is to the motor 105, the lower the height at which the centrifugal extractor body 100 is lifted.

[0061] This can further reduce the requirements for the installation height of the plant when installing large equipment and improve the efficiency of installing or skid-mounting the centrifugal extractor body 100 and frame 200.

[0062] For example, the outer side wall of the lower part 103 of the housing has an extension in the horizontal direction, and the extension is fixedly connected to the mounting base 1.

[0063] It should be noted that the extension and the downward stepped surface 104 can be located on the same horizontal plane and can be integrally formed; or the extension can be located below the downward stepped surface 104. The extension can be fixedly connected to the mounting base 1, and the downward stepped surface 104 can also be fixedly connected to the mounting base 1. Depending on the actual situation, as long as the body 100 of the centrifugal extractor can be fixed to the frame 200, it is acceptable.

[0064] For example, the body 100 of the centrifugal extractor is cylindrical, and the outer side wall of the cylindrical shape has an extension in the horizontal direction, which is connected to the mounting base 1.

[0065] It is understood that the extension and the mounting base 1 can be fixedly connected by snap-fit, bolt connection, welding or other connection methods. The connection method between the extension and the mounting base 1 is not limited here.

[0066] An embodiment of the frame of the quick-release centrifugal extractor of this utility model:

[0067] The frame of the quick-release centrifugal extractor in this embodiment has the same structure as the frame in any of the above embodiments of the quick-release centrifugal extractor, and will not be described again here.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
