Description

Technical Field

[0001] The invention belongs to the field of petrochemical equipment, and in particular relates to a separator support structure and a low-pressure separator. Background Art

[0002] The purpose of the low-pressure separator is to further separate the product, and the material directly enters the extruder for cutting. This equipment is connected to the extruder feed port through the bottom discharge port. In normal operation, the weight of this separator is supported on the extruder, but during on-site installation or maintenance, this separator is separated from the extruder, and the equipment is supported by the ear seat. The support position is different under different working conditions, and the temperature rises during operation, and the vertical and radial expansion is required, as well as the large horizontal thrust brought by the extruder. Therefore, it is necessary to achieve both vertical and horizontal movement, which is also the key to the design of such equipment.

[0003] Usually this type of vertical equipment adopts two forms of support. One is to use ear-type support. The ear is fixed on the steel structure beam, and a large round hole or oblong hole is opened on the bottom plate of the ear. It can move a little in the horizontal direction, but cannot move in the vertical direction. This direction is constrained and cannot meet the requirements of temperature increase and expansion. The second is that the separator is directly connected to the extruder without an ear. However, during on-site inspection and maintenance, once the separator is disassembled from the extruder, there is no support point, and a crane or other lifting equipment must be used to lift the separator, which increases the inspection and maintenance costs, as well as the safety risks during inspection and maintenance. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a separator support structure and a low-pressure separator, which can realize the separator to be movable in the vertical direction and the horizontal direction, so that the separator is supported in different positions during operation, installation or maintenance conditions, respectively, to meet the thermal expansion and force requirements.

[0005] One of the objects of the present invention is to provide a separator support structure.

[0006] A second object of the present invention is to provide a low-pressure separator.

[0007] The present invention is achieved through the following technical solutions:

[0008] A first aspect of the present invention provides a separator support structure, comprising:

[0009] The ear seat comprises a cover plate, a bottom plate and a base plate which are parallel and horizontally arranged to each other, and one side of the cover plate, the bottom plate and the base plate are commonly connected to an ear seat pad;

[0010] The rotary buffer support assembly is arranged between the bottom plate and the base plate.

[0011] The rotating buffer support assembly enables the separator to move in both vertical and horizontal directions when the temperature rises, and can flexibly switch the support points under different working conditions. During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks.

[0012] A further improvement of the present invention is that

[0013] The rotary buffer support assembly comprises:

[0014] A steel beam is arranged below the bottom plate, and pads are fixed on the upper and lower surfaces of the steel beam;

[0015] The sleeve has connecting plates at both ends, and the two connecting plates are rotatably connected to the two pads respectively. Bolts are arranged in the sleeve, and two of the bolts pass through the bottom plate and the base plate respectively.

[0022] A further improvement of the present invention is:

[0023] Through holes are provided at the relative positions of the other ends of the upper connecting plate and the lower connecting plate, and the two ends of the sleeve are respectively inserted into the two through holes and welded together.

[0024] A further improvement of the present invention is:

[0025] There is a radial gap between the sleeve and the bolt, that is, the inner diameter of the sleeve is larger than the diameter of the bolt.

[0026] A further improvement of the present invention is:

[0027] There is a first distance between the upper end of the sleeve and the bottom plate, and there is a second distance between the lower end of the sleeve and the base plate, so that the bolt can move up and down in the sleeve.

[0028] A further improvement of the present invention is:

[0029] The cover plate and the other end of the bottom plate are respectively provided with first ribs on both sides, the upper and lower ends of the first ribs are respectively welded to the cover plate and the bottom plate, and one end of the first rib close to the pad is welded to the ear seat pad.

During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks.

[0037] During operation, the separator expands vertically and radially due to the temperature increase, and the separator moves horizontally due to the large thrust brought by the extruder directly connected to the separator.

DETAILED DESCRIPTION

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0043] [Example 1]

[0044] The present invention provides a separator support structure, such as Figure 1 , Figure 2 and Figure 3 As shown, including:

[0045] The ear seat comprises a cover plate 1, a bottom plate 2 and a base plate 3 which are arranged parallel to each other and horizontally, and one side of the cover plate 1, the bottom plate 2 and the base plate 3 is commonly connected with an ear seat pad 4, and the ear seat pad 4 is welded to the outer wall of the equipment cylinder 15, and is used to fix the entire separator support structure on the equipment cylinder 14;

[0046] The rotating buffer support assembly is arranged between the bottom plate 2 and the base plate 3 .

[0047] Furthermore, the rotation buffer support assembly includes:

[0048] A steel beam 5 is arranged below the bottom plate 2, and pads are fixed on the upper and lower surfaces of the steel beam 5;

[0049] The sleeve 6 is provided with connecting plates at both ends, and the two connecting plates are rotatably connected to the two pads respectively. A bolt 7 is provided in the sleeve 6, and both ends of the bolt 7 pass through the bottom plate 2 and the base plate 3 respectively.

[0050] The present invention improves the conventional ear seat support form, and can flexibly switch the support point under different working conditions. During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks. During operation, the temperature rise causes the separator to expand vertically and radially, and the large thrust brought by the extruder directly connected to the separator causes the separator to move horizontally. The present invention inserts the bolt into the sleeve, and then rotates the sleeve to connect it to the steel beam, and there is a radial gap between the sleeve and the bolt, a first spacing between the upper end of the sleeve and the bottom plate, and a second spacing between the lower end of the sleeve and the base plate, so that the bolt can move up and down or horizontally in the sleeve, thereby realizing the vertical and horizontal movement of the separator under temperature rise.

[0051] The present invention can realize that the separator can be moved in both vertical and horizontal directions when the temperature rises, and can flexibly switch the support points under different working conditions. During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks.

[0052] [Example 2]

[0053] The steel beam 5 is an I-beam or H-shaped steel structure.

[0054] The pad includes an upper pad 8 and a lower pad 9. The upper pad 8 is arranged on the upper surface of the steel beam 5 and fixed by bolts, and the lower pad 9 is arranged on the lower surface of the steel beam 5 and fixed by bolts. During on-site installation or maintenance, the equipment (low-pressure separator) is entirely supported on the steel beam 5.

[0055] [Example 3]

[0056] The connecting plate includes an upper connecting plate 10 and a lower connecting plate 11, one end of the upper connecting plate 10 is rotatably connected to the upper pad 8 by screws, and one end of the lower connecting plate 11 is rotatably connected to the lower pad 9 by screws. Preferably, the screw connection position of the upper connecting plate 10 and the upper pad 8 is adapted to the screw connection position of the lower connecting plate 11 and the lower pad 9, so that the rotation angle and direction of the upper connecting plate 10 and the lower connecting plate 11 are always the same;

[0057] The sleeve 6 is arranged between the other ends of the upper connecting plate 10 and the lower connecting plate 11. Specifically, through holes are arranged at the relative positions of the other ends of the upper connecting plate 10 and the lower connecting plate 11, and the two ends of the sleeve 6 are respectively inserted into the two through holes and welded together, so that the sleeve 6 cannot move in the vertical direction, but the sleeve 6 can rotate horizontally circumferentially with the upper connecting plate 10 and the lower connecting plate 11 with the screw as the center of the circle. Since four separator support structures are usually evenly arranged along the circumference on the outer wall of the low-pressure separator, the horizontal circumferential rotation of the sleeve 6 has a certain self-limiting property due to the interaction of the ear seat structures in four directions.

[0058] [Example 4]

[0059] A bolt 7 is disposed in the sleeve 6 , and two ends of the bolt 7 pass through the bottom plate 2 and the base plate 3 respectively.

[0060] There is a radial gap between the sleeve 6 and the bolt 7, that is, the inner diameter of the sleeve 6 is larger than the diameter of the bolt 7, so that the bolt 7 can be horizontally displaced in any direction in the sleeve 6, so that the low-pressure separator can have a certain horizontal displacement in the radial direction.

[0061] The radial clearance between the sleeve 6 and the bolt 7, that is, the difference between the inner diameter of the sleeve 6 and the diameter of the bolt 7, can be determined based on the horizontal expansion of the low-pressure separator after heating and the horizontal displacement caused by the horizontal thrust.

[0062] There is a first distance between the upper end of the sleeve 6 and the bottom plate 2, and there is a second distance between the lower end of the sleeve 6 and the base plate 3, so that the bolt 7 can move up and down in the sleeve.

[0063] [Example 5]

[0064] One end of the cover plate 1, the bottom plate 2 and the base plate 3 are all welded to the ear seat pad 4, and first ribs 12 are respectively provided on both sides of the other ends of the cover plate 1 and the bottom plate 2, and the upper and lower ends of the first ribs 12 are respectively welded to the cover plate 1 and the bottom plate 2, and one end of the first rib 12 close to the ear seat pad 4 is welded to the ear seat pad 4. The first ribs 12 play a role in reinforcing and supporting the ear seat.

[0065] A second rib plate 13 is provided between the upper connecting plate 10 and the lower connecting plate 11 , and two ends of the second rib plate 13 are respectively welded to the upper connecting plate 10 and the lower connecting plate 11 , and the second rib plate 13 plays a reinforcing and supporting role for the upper connecting plate 10 and the lower connecting plate 11 .

[0066] A third rib plate 14 is provided between the bottom plate 2 and the base plate 3 , and two ends of the third rib plate 14 are welded to the bottom plate 2 and the base plate 3 , respectively. The third rib plate 14 plays a role in reinforcing and supporting the bottom plate 2 and the base plate 31 .

[0067] During installation or maintenance, the separator falls down, the ear seat bottom plate 2 presses against the upper end of the sleeve 6, and the weight of the separator is supported on the steel beam 5. During operation, the material in the separator heats up and expands upward, and the bolts 7, the bottom plate 2, and the base plate 3 move upward with the separator. At this time, the steel beam 5 no longer supports the separator, thereby realizing the vertical movement of the separator; the separator heats up and expands radially, or the equipment moves horizontally due to the horizontal thrust of the extruder, the bolts 7 and the ear seat move horizontally with the equipment, driving the connection assembly composed of the sleeve 6 and the connecting plate to rotate horizontally, thereby realizing the horizontal movement of the separator.

[0068] [Example 6]

[0069] The embodiment of the present invention further provides a low-pressure separator, which includes a separator cylinder, and a separator support structure is arranged on the outer wall of the separator cylinder.

[0070] The separator support structure is usually arranged at the part below the center of gravity of the separator, and four of them are evenly arranged along the circumferential direction on the outer wall of the cylinder.

[0071] like Figure 1 , Figure 2 and Figure 3 As shown, the separator support structure includes:

[0072] The ear seat comprises a cover plate 1, a bottom plate 2 and a base plate 3 which are arranged parallel to each other and horizontally. One side of the cover plate 1, the bottom plate 2 and the base plate 3 is commonly connected with an ear seat pad 4, and the ear seat pad 4 is welded to the outer wall of the equipment cylinder 15, and is used to fix the entire separator support structure on the equipment cylinder 14; the shape of the ear seat pad 4 is adapted to the shape of the cylinder 15, so that the ear seat pad 4 can be closely attached to the outer wall of the cylinder 15;

[0073] A steel beam 5 is arranged below the bottom plate 2, and pads are fixed on the upper and lower surfaces of the steel beam 5;

[0074] The sleeve 6 is provided with connecting plates at both ends, and the two connecting plates are rotatably connected to the two pads respectively. A bolt 7 is provided in the sleeve 6, and both ends of the bolt 7 pass through the bottom plate 2 and the base plate 3 respectively.

[0075] The present invention can realize that the separator can be moved in both vertical and horizontal directions when the temperature rises, and can flexibly switch the support points under different working conditions. During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks.

[0076] During installation or maintenance, the separator falls down, the ear seat bottom plate 2 presses against the upper end of the sleeve 6, and the weight of the separator is supported on the steel beam 5. During operation, the material in the separator heats up and expands upward, and the bolts 7, the bottom plate 2, and the base plate 3 move upward with the separator. At this time, the steel beam 5 no longer supports the separator, thereby realizing the vertical movement of the separator; the separator heats up and expands radially, or the equipment moves horizontally due to the horizontal thrust of the extruder, the bolts 7 and the ear seat move horizontally with the equipment, driving the connection assembly composed of the sleeve 6 and the connecting plate to rotate horizontally, thereby realizing the horizontal movement of the separator.

[0077] The present invention improves the conventional ear seat support form, and can flexibly switch the support point under different working conditions. During inspection and maintenance, there is no need to add lifting equipment for additional support, which saves costs and reduces on-site safety risks. During operation, the temperature rise causes the separator to expand vertically and radially, and the large thrust brought by the extruder directly connected to the separator causes the separator to move horizontally. The present invention inserts the bolt into the sleeve, and then rotates the sleeve to connect it to the steel beam, and there is a radial gap between the sleeve and the bolt, a first spacing between the upper end of the sleeve and the bottom plate, and a second spacing between the lower end of the sleeve and the base plate, so that the bolt can move up and down or horizontally in the sleeve, thereby realizing the vertical and horizontal movement of the separator under temperature rise.
