Description

TECHNICAL FIELD

[0001] The utility model belongs to acetone recovery technical field, especially, it relates to the lightweight support frame of acetone recovery tower. BACKGROUND

[0002] The acetone recovery tower is an industrial equipment for separating and recycling acetone and other organic solvents, widely used in chemical industry, pharmaceutical industry, paint industry and other industries. Its core function is to purify and recycle acetone in mixed liquid through distillation, condensation and other physical processes, which reduces raw material consumption and environmental pollution. The working principle is based on the difference in boiling point between acetone and other components, and the separation is realized by using rectification technology in the tower. The mixed liquid is preheated and enters from the middle of the tower, and the steam is generated by heating the reboiler at the bottom of the tower, which rises and contacts with the reflux liquid at the top in the packing layer or tray multiple times. The low-boiling-point acetone vapor is liquefied in the condenser at the top and recovered, and the high-boiling-point impurities are discharged from the bottom of the tower.

[0003] The support frame of the acetone recovery tower needs to bear the weight of the tower body, the medium pressure and the environmental vibration load for a long time. The existing support frame of the acetone recovery tower adopts an integral steel structure or a casting part, which has the problems of large volume, difficult transportation and installation, and low stability. With the increasing demand for lightweight and modular design of chemical equipment, we provide a lightweight support frame for the acetone recovery tower to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a lightweight support frame for the acetone recovery tower, which solves the problems of large volume, difficult transportation and installation and poor stability of the support frame of the acetone recovery tower in the prior art through the cooperation of the splicing assembly and the reinforcing assembly.

[0005] To solve the above technical problems, the utility model is realized by the following technical scheme.

[0006] The utility model is a lightweight support frame for the acetone recovery tower, which comprises an acetone recovery tower body and a support frame arranged on one side of the acetone recovery tower body. A splicing assembly is arranged in the inner cavity of the support frame. The splicing assembly comprises a main threaded rod movably connected to the inner cavity of the support frame through a bearing seat, a threaded sleeve sleeved on the surface of the main threaded rod, an installation plate fixed on the surface of the threaded sleeve, a fixed frame fixedly connected to one side of the installation plate, an extension frame arranged on the top of the support frame, and an extension threaded rod arranged in the inner cavity of the extension frame. A reinforcing assembly is arranged at the bottom of the support frame. The reinforcing assembly comprises a base fixedly connected to the bottom of the support frame, extension blocks arranged on both sides of the base, and triangular reinforcing blocks sliding on both sides of the support frame.

[0007] The present invention is further configured such that a fixed shaft is movably connected to the inner wall of the support frame through a bearing seat, and a driving bevel gear is fixedly connected to one end of the fixed shaft. A driven bevel gear meshes with the surface of the driving bevel gear. Through the cooperation of the driving bevel gear and the driven bevel gear, the handle is manually rotated, and the handle drives the driving bevel gear to rotate through the fixed shaft. The driving bevel gear drives the main threaded rod to rotate through the driven bevel gear.

[0008] The present invention is further configured such that the other end of the fixed shaft passes through the support frame and is fixedly connected to a handle wheel, and the driven bevel gear shaft is fixedly connected to the surface of the main thread rod.

[0009] The present invention is further provided that the support frame and the extension frame are provided with positioning holes on the back, and the extension frame is provided with a positioning plate on the back. By means of the cooperation of the positioning holes and the positioning plate, the extension frame can be spliced ​​and installed with the corresponding support frame by means of the mounting bolts and the positioning plate, thereby reducing the volume of the bracket and facilitating transportation.

[0010] The present invention is further configured such that the top of both the main threaded rod and the extension threaded rod are provided with mounting holes, and the bottom of the extension threaded rod is provided with a plug. Both the mounting holes and the surface of the plug are provided with threaded holes. By assembling the bottom plug of the extension threaded rod with the top mounting hole of the main threaded rod, and then fixing it with mounting bolts, the operation is simple and convenient for splicing threaded rods.

[0011] The present invention is further configured such that fixing grooves are provided on both sides of the base, and the extension block is rotatably connected to the inner cavity of the fixing groove via a rotating shaft.

[0012] The present invention is further configured such that a limiting block is fixedly connected to one side of the extension frame, and a limiting groove is provided at the bottom of the triangular reinforcing block. The cooperation between the limiting block and the limiting groove facilitates the limiting of the extension block.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model, by setting up splicing components and using the axial splicing design of the main threaded rod and the extension threaded rod, combined with positioning holes, insert blocks and limiting structures, realizes the rapid assembly and height adjustment of the support frame, realizes the multi-level expansion of the support frame, significantly reduces the transportation volume and improves the on-site installation efficiency; the semi-circular fitting design of the fixed frame and the extension frame reduces the amount of material used while ensuring the contact area with the tower body and avoids local stress concentration.

[0015] 2. By setting up a reinforcing component and fixing it with a sliding triangular reinforcing block and a pin, this utility model can form a stable triangular support surface after unfolding, which significantly improves the anti-overturning ability of the base. The detachable splicing component means that only the corresponding module needs to be replaced when there is partial damage, avoiding the scrapping of the entire frame and reducing maintenance costs.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Further details: There are several fixed frames 6 and several extended threaded rods 8, which can be spliced ​​together as needed. The fixed frame 6 is semi-circular in shape so that it can better fit the equipment to be supported. The support frame 2 has grooves on both the front and back that are adapted to the triangular reinforcing block 11. The triangular reinforcing block 11 and the support frame 2 have fixing holes on both the front and back. By inserting pins (which are basic connecting parts and therefore not described) into the corresponding fixing holes, the triangular reinforcing block 11 can be limited, which can ensure the overall stability of the support frame 2.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a fixed shaft 12 is movably connected to the inner wall of the support frame 2 via a bearing seat. One end of the fixed shaft 12 is fixedly connected to a driving bevel gear 13, and a driven bevel gear 14 meshes with the surface of the driving bevel gear 13. The other end of the fixed shaft 12 passes through the support frame 2 and is fixedly connected to a handle wheel 15. The shaft center of the driven bevel gear 14 is fixedly connected to the surface of the main threaded rod 3. Positioning holes 16 are provided on the back of both the support frame 2 and the extension frame 7. A positioning plate 17 is provided on the back of the extension frame 7. Mounting holes 18 are provided on the top of both the main threaded rod 3 and the extension threaded rod 8. An insert block 19 is provided at the bottom of the extension threaded rod 8. Fixing grooves 20 are provided on both sides of the base 9. The extension block 10 is rotatably connected to the inner cavity of the fixing groove 20 via a rotating shaft. A limiting block 21 is fixedly connected to one side of the extension frame 7. A limiting groove 22 is provided at the bottom of the triangular reinforcing block 11.

[0030] Further details: By manually rotating the handle through the cooperation of the driving bevel gear 13 and the driven bevel gear 14, the handle drives the driving bevel gear 13 to rotate via the fixed shaft 12. The driving bevel gear 13 then drives the main threaded rod 3 to rotate via the driven bevel gear 14. Through the cooperation of the positioning hole 16 and the positioning plate 17, the extension frame 7 can be spliced ​​and installed with the corresponding support frame 2 by the mounting bolts and the positioning plate 17, reducing the volume of the bracket and facilitating transportation. The mounting hole 18 and the insert block 19 are both provided with threaded holes. By assembling the bottom insert block 19 of the extension threaded rod 8 with the top mounting hole 18 of the main threaded rod 3, and then fixing it with mounting bolts, the operation is simple and convenient for splicing between threaded rods. Through the cooperation of the limiting block 21 and the limiting groove 22, the extension block 10 can be limited.

[0031] The working principle of this utility model is as follows: move the support frame 2 to the designated position, then manually push one end of the triangular reinforcing block 11 upward to disengage the limiting block 21 from the limiting groove 22. At this time, manually flip the extension block 10 to make the extension block 10 horizontal. Then slide the triangular reinforcing block 11 downward and fix the triangular reinforcing block 11 with a pin to reduce the volume in the storage state while ensuring the stability of the support frame 2.

[0032] First, assemble the bottom insert 19 of the extension threaded rod 8 with the top mounting hole 18 of the main threaded rod 3, and then fix it with mounting bolts. Then, the extension frame 7 and the corresponding support frame 2 can be spliced ​​and installed with the mounting bolts and positioning plate 17 as needed. After splicing, manually rotate the handle. The handle drives the active bevel gear 13 to rotate through the fixed shaft 12. The active bevel gear 13 drives the main threaded rod 3 to rotate through the driven bevel gear 14. During the coaxial rotation of the main threaded rod 3 and the extension threaded rod 8, the threaded sleeve 4 drives the mounting plate 5 to move upward. The mounting plate 5 drives the fixed frame 6 to move upward to support the equipment to be supported. When the equipment is running, the triangular reinforcement block 11 and the extension block 10 of the base 9 are locked by the pin to resist lateral vibration. The support frame 2, the triangular reinforcement block 11 and the base 9 form a three-level force transmission path, effectively dispersing the tower load to the foundation.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
