Description

Technical Field

[0001] This utility model belongs to the field of petroleum processing technology, and more specifically, it relates to a distillation apparatus for petroleum refining. Background Technology

[0002] Atmospheric distillation towers are the most commonly used distillation equipment in the petroleum refining process. They heat crude oil to vaporization under atmospheric pressure and cut the crude oil into fractions such as gasoline, kerosene, diesel, wax oil, and residual oil according to their boiling points. Each fraction is used as feedstock for subsequent processing (such as catalytic cracking, hydrorefining, coking, etc.), realizing the initial separation of crude oil and laying the foundation for the entire refining process. Existing atmospheric distillation towers generally consist of a tower body assembled from multiple tower sections, internal mass transfer components, material inlet and outlet and heat exchange systems, as well as auxiliary pipelines and connecting components.

[0003] Existing application number: CN202220573547.0, this utility model discloses a distillation apparatus for petroleum refining, including a heating device, a stirring and cleaning device, a filtering device, a condensing device, and a collecting device. The heating device includes a heating tank, with electric heating tubes wound around its side walls. The top of the heating tank is provided with a crude oil inlet, a temperature measuring hole, and a gas outlet pipe. The stirring and cleaning device is installed at the center of the top of the heating tank. The stirring and cleaning device includes a stirring motor, which is installed at the center of the top of the heating tank. A central shaft is fixed on the output shaft of the stirring motor, and a stirring rod is welded to the central shaft. A spiral scraper is welded to the other end of the stirring rod, and the cutting edge of the spiral scraper is in close contact with the inner wall of the heating tank. This utility model can promptly scrape off the residue adhering to the inner wall of the heating tank; it can filter out the scraped residue from the heating tank, preventing the residue from affecting the purity of the refining process.

[0004] Based on the above, when splicing the upper and lower tower sections of an atmospheric distillation column, the flange holes of the upper and lower tower sections are difficult to align quickly and accurately due to the influence of hoisting errors, the weight of the tower sections, and the lack of reliable auxiliary positioning structures. This requires repeated adjustments, which is not only time-consuming and labor-intensive, but may also damage the sealing surface due to forced splicing, increasing the risk of leakage. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a distillation apparatus for petroleum refining. This solves the problem that existing atmospheric distillation towers, when splicing the upper and lower tower sections, suffer from lifting errors, the tower's own weight, and a lack of reliable auxiliary positioning structures. This results in difficulty in quickly and accurately aligning the flange holes of the upper and lower tower sections, requiring repeated adjustments that are not only time-consuming and labor-intensive but may also damage the sealing surface due to forced splicing, increasing the risk of leakage.

[0006] The purpose and effect of this utility model, a distillation apparatus for petroleum refining, are achieved by the following specific technical means:

Multiple fixed connecting blocks are disposed and fixedly connected to the front and rear sides of the bottom of multiple sections of the distillation column body. Multiple fixed docking blocks are disposed and fixedly connected to the front and rear sides of the top of multiple sections of the distillation column body. Multiple positioning boxes are disposed and fixedly connected to the front and rear sides of the top of multiple sections of the distillation column body. The protective box is... Multiple protective boxes are provided, and these protective boxes are distributed and fixedly connected to the front and rear sides of the top of the main body of the distillation column. Multiple transmission boxes are provided, and these transmission boxes are respectively fixedly connected to the top of the multiple protective boxes. Multiple lifting rings are provided, and these lifting rings are respectively located inside the multiple protective boxes and distributed and fixedly connected to the front and rear sides of the top of the main body of the distillation column. Multiple sets of auxiliary positioning components are provided, and these sets of auxiliary positioning components are respectively located inside and above the multiple fixed docking blocks. Multiple sets of protective components are provided, and these sets of protective components are respectively located on the top of the multiple protective boxes.

[0008] Furthermore, the auxiliary positioning component includes a conical block and a conical groove; the conical block is fixedly connected to the bottom of the fixed connecting block; the conical groove is formed inside the fixed docking block.

[0009] Furthermore, the auxiliary positioning component also includes: a sliding block, a transmission screw, and an operating knob; the sliding block is slidably connected inside the positioning box; the transmission screw is rotatably connected inside the positioning box, and the transmission screw is threadedly connected to the sliding block; the operating knob is coaxially fixedly connected to the right end of the transmission screw.

[0010] Furthermore, the auxiliary positioning component also includes: a positioning block, a first positioning groove, and a second positioning groove; the positioning block is fixedly connected to the left side of the sliding block; two first positioning grooves are provided, and the two first positioning grooves are distributed inside the fixed docking block; the second positioning groove is provided inside the conical block.

[0011] Furthermore, the protective assembly includes: a sliding rack, a sliding plate, a transmission column, and a jacking spring; the sliding rack is slidably connected inside the transmission box; the top of the sliding plate is fixedly connected to the right side of the sliding rack; the transmission column is fixedly connected to the bottom right side of the sliding plate; the right end of the jacking spring is fixedly connected to the left side of the sliding rack, and the left end of the jacking spring is fixedly connected inside the transmission box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the conical block and conical groove of the auxiliary positioning component are initially aligned with the tower body, and the positioning block is inserted into the positioning groove by the transmission screw. This achieves precise positioning when splicing the upper and lower tower bodies, avoiding flange hole misalignment caused by hoisting errors and the self-weight of the tower body. This facilitates subsequent flange connection, reduces the time and effort required for repeated adjustments, effectively prevents damage to the sealing surface caused by forced splicing, and improves the efficiency and sealing of tower body splicing.

[0015] Secondly, by utilizing the linkage structure of the sliding rack and transmission gear of the protective component, the shielding plate is automatically driven to seal the protective box when the tower body is spliced ​​and positioned, reducing the erosion of the lifting ring by rainwater and dust and lowering the probability of rust on the lifting ring. At the same time, the water-permeable holes at the bottom of the protective box can quickly drain the infiltrated rainwater. When hoisting is required, the shielding plate automatically opens without affecting the use of the lifting ring, thus achieving a balance between the protection of the lifting ring and the convenience of operation.

[0016] This invention achieves precise positioning during tower assembly, eliminates flange connection deviations caused by hoisting errors, improves assembly efficiency and ensures sealing. It automatically drives the protective shielding rings during tower positioning, reducing the risk of corrosion, while also ensuring ease of hoisting operations. These improvements not only shorten the installation time and cost of the tower, ensuring rapid commissioning of the refining unit, but also extend the service life of key components such as the lifting rings through the protective design of the mechanical structure, reducing equipment maintenance frequency and further enhancing the safety and reliability of the oil refining process.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] Example 1:

[0028] As attached Figure 1 To be continued Figure 7 As shown:

[0029] This utility model provides a distillation apparatus for petroleum refining, including a distillation tower body 1, fixed connecting blocks 2, fixed docking blocks 3, positioning boxes 4, protective boxes 7, transmission boxes 701, lifting rings 8, and auxiliary positioning components; multiple fixed connecting blocks 2 are provided, and the multiple fixed connecting blocks 2 are distributed and fixedly connected to the front and rear sides of the bottom of multiple tower sections of the distillation tower body 1; multiple fixed docking blocks 3 are provided, and the multiple fixed docking blocks 3 are distributed and fixedly connected to the front and rear sides of the top of multiple tower sections of the distillation tower body 1; multiple positioning boxes 4 are provided, and the multiple positioning boxes 4 are distributed and fixedly connected to the distillation tower. The main body 1 has multiple tower sections on the front and rear sides of the top; multiple protective boxes 7 are provided, and the multiple protective boxes 7 are dispersedly and fixedly connected to the front and rear sides of the top of the multiple tower sections of the main body 1; multiple transmission boxes 701 are provided, and the multiple transmission boxes 701 are respectively fixedly connected to the top of the multiple protective boxes 7; multiple lifting rings 8 are provided, and the multiple lifting rings 8 are respectively located inside the multiple protective boxes 7, and the multiple lifting rings 8 are dispersedly and fixedly connected to the front and rear sides of the top of the multiple tower sections of the main body 1; multiple sets of auxiliary positioning components are provided, and the multiple sets of auxiliary positioning components are respectively located inside and above the multiple fixed docking blocks 3.

[0030] The auxiliary positioning components include a conical block 201 and a conical groove 301; the conical block 201 is fixedly connected to the bottom of the fixed connecting block 2; the conical groove 301 is formed inside the fixed docking block 3.

[0031] The auxiliary positioning component also includes: a sliding block 5, a transmission screw 6, and an operating knob 601; the sliding block 5 is slidably connected inside the positioning box 4; the transmission screw 6 is rotatably connected inside the positioning box 4, and the transmission screw 6 is threadedly connected to the sliding block 5; the operating knob 601 is coaxially fixedly connected to the right end of the transmission screw 6.

[0032] The auxiliary positioning component also includes: a positioning block 501, a first positioning groove 302 and a second positioning groove 202; the positioning block 501 is fixedly connected to the left side of the sliding block 5; two first positioning grooves 302 are provided, and the two first positioning grooves 302 are provided separately inside the fixed docking block 3; the second positioning groove 202 is provided inside the conical block 201.

[0033] The specific usage and function of this embodiment: When splicing the upper distillation column body 1 with the lower distillation column body 1, a crane or other mechanical equipment is used to lift the upper distillation column body 1 using lifting rings 8. Then, the conical block 201 of the upper distillation column body 1 is aligned with the conical groove 301 of the lower distillation column body 1 and inserted, thus temporarily aligning the two distillation column bodies 1. The conical structure of the conical block 201 and the conical groove 301 makes the insertion process more convenient. It is more convenient and faster; then, turn the operating knob 601, and the threaded transmission mechanism composed of the transmission screw 6 and the sliding block 5 will drive the sliding block 5 and the positioning block 501 to move to the left. The positioning block 501 is inserted into the first positioning groove 302 and the second positioning groove 202, so that the conical block 201 can be firmly fixed in the conical groove 301. This makes it easier to use traditional components such as flanges and bolts to fasten the upper and lower distillation column bodies 1 together. The alignment of the holes in the flanges and bolts is more precise and efficient.

[0034] Example 2:

[0035] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 7 As shown, it also includes protective components, with multiple sets of protective components, each set of which is located on the top of the multiple protective boxes 7.

[0036] The protective components include: a sliding rack 9, a sliding plate 901, a transmission column 902, and a jacking spring 903; the sliding rack 9 is slidably connected inside the transmission box 701; the top of the sliding plate 901 is fixedly connected to the right side of the sliding rack 9; the transmission column 902 is fixedly connected to the bottom right side of the sliding plate 901; the right end of the jacking spring 903 is fixedly connected to the left side of the sliding rack 9, and the left end of the jacking spring 903 is fixedly connected inside the transmission box 701.

[0037] The protective assembly also includes: a connector 10, a first drive shaft 11, a drive gear 1101, and a shield 1102; two connectors 10 are provided, and the two connectors 10 are separately and fixedly connected to the top right side of the protective box 7; the first drive shaft 11 is rotatably connected to the inside of the two connectors 10; the drive gear 1101 is coaxially and fixedly connected to the front end of the first drive shaft 11; the right end of the shield 1102 is fixedly connected to the outside of the first drive shaft 11.

[0038] The specific usage and function of this embodiment are as follows: When the positioning block 501 is inserted into the first positioning groove 302 on the left, after contacting the right end of the transmission column 902, it will push the transmission column 902 to the left, thereby driving the sliding plate 901 and the sliding rack 9 to move to the left synchronously. During this process, the push spring 903 will be compressed. Then, through the gear and rack transmission mechanism formed by the meshing of the sliding rack 9 and the transmission gear 1101, the first transmission shaft 11 will be driven to rotate inside the two connecting parts 10, thereby driving the baffle plate 1102 to swing around the first transmission shaft 11 as the axis, so that the baffle plate 1102 can block the upper opening of the protective box 7, greatly reducing rain. Contact between water, dust, and other contaminants with the lifting rings 8 inside the protective box 7 reduces the probability of corrosion of the lifting rings 8. At the same time, the bottom of the protective box 7 has a water-permeable hole, which allows rainwater that seeps into the protective box 7 to be drained quickly. When it is necessary to lift the main body of the distillation tower 1, first turn the operating knob 601 in the opposite direction to disengage the positioning block 501 from the first positioning groove 302 on the left. During the process, the push spring 903 rebounds, causing the sliding rack 9 to move to the right. This, together with the transmission gear 1101, forms a gear and rack transmission mechanism that drives the baffle 1102 to open, making it easier to connect the rope to the lifting rings 8 inside the protective box 7. This makes the operation more efficient and convenient.
