Description

Technical Field

[0001] This utility model belongs to the field of leaching device technology, specifically relating to a leaching section and a leaching device including the aforementioned leaching section. Background Technology

[0002] Leaching units are large pieces of equipment in oil refineries, often among the first large pieces to arrive at the project site during the initial construction phase. Due to their structure, leaching units require manufacturing as several components at the factory, while on-site assembly and welding of these components present the following technical challenges:

[0003] 1. The overall manufacturing time and precision of the large shell are difficult to control;

[0004] 2. The excessive overall height places higher demands on transportation;

[0005] 3. Some components require on-site assembly, which presents significant challenges in connection.

[0006] 4. The labor intensity of on-site installation work is relatively high.

[0007] For example, the assembly and welding of the lower oil hoppers requires hoisting each oil hopper to the corresponding position at the bottom of the leaching tank shell and then welding it after it comes into contact with the shell. If it is a large-tonnage leaching tank, the number of lower oil hoppers is large and their volume is large, which will increase the workload and labor intensity of on-site assembly and welding.

[0008] Therefore, how to reduce the workload and difficulty of such large equipment on the engineering site is an urgent problem to be solved. Utility Model Content

[0009] The first objective of this invention is to provide a leaching section that addresses the technical problems of existing leaching devices, such as long manufacturing time, low manufacturing precision, difficult transportation, high on-site assembly difficulty, and high labor intensity.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a leaching section, characterized in that it includes:

[0011] The first leaching section includes a first shell assembly; a first filter screen assembly and a first oil hopper assembly are disposed on the first shell assembly.

[0012] The second leaching section is disposed above the first leaching section. The second leaching section includes a second housing assembly, on which a second filter screen assembly, a second oil hopper assembly, and a spray assembly are disposed.

[0013] A positioning connection component is disposed on the second leaching section and the first leaching section, for connecting the first leaching section and the second leaching section.

[0014] This invention divides the shell's total leaching section into upper and lower leaching circulation sections based on function. During manufacturing, the upper and lower leaching circulation sections can be produced in two separate shifts, reducing the overall manufacturing time and difficulty of the shell.

[0015] This utility model is designed with upper and lower leaching circulation sections, which are transported separately. The segmented structure reduces the overall height and lowers the requirements for transportation.

[0016] The leaching section of this invention, upon arrival at the engineering site, follows a bottom-up installation sequence, enabling accurate and rapid hoisting into place without requiring additional manual installation, effectively reducing on-site installation time and labor intensity. The functional segmentation and bottom-up installation sequence of this invention reduce installation difficulty and time; the standard segment placement with guide positioning improves installation accuracy, facilitates welding, and eliminates the need for additional tooling or manual labor.

[0017] To address the technical problem of how to implement the first housing assembly, this utility model adopts the following technical solution: the first housing assembly includes two first side plates, and a first reinforcing component is provided on the first side plates, including:

[0018] The first transverse reinforcement is disposed on the first side plate and is arranged along the length direction of the first side plate; the upper surface of the uppermost first transverse reinforcement is flush with the upper edge of the first side plate, or the upper surface of the uppermost first transverse reinforcement is in contact with the bent edge of the first side plate.

[0019] The first vertical reinforcement is disposed between the first horizontal reinforcements that are adjacent to each other.

[0020] This invention utilizes a first reinforcing component to ensure the strength of the first side plate, effectively guaranteeing the strength of the upper leaching section.

[0021] To address the technical problem of deformation of the first shell assembly during transportation of the first leaching section, which is formed by welding together structural steel and sheet metal, this utility model adopts the following technical solution: a first limiting assembly is detachably installed on the first leaching section to prevent deformation of the first side plate of the first leaching section during transportation. The first limiting assembly includes:

[0022] A first limiting plate is disposed between the two first side plates;

[0023] The first limiting buckle is used to restrict the first limiting plate to the uppermost first transverse reinforcement and to limit it by a stop limiting pin. The lower end of the stop limiting pin passes through the first limiting plate and the first transverse reinforcement in sequence. The upper end of the stop limiting pin is provided with a first locking element.

[0024] In this utility model, the first limiting plate in the first limiting assembly is installed between the two first side plates of the first housing assembly, thereby limiting the inward deformation of the first housing assembly and preventing the first housing assembly of the first leaching section from deforming.

[0025] To further address the technical issue of how the first limiting component is specifically implemented, this utility model adopts the following technical solution: the stop limiting pin includes a screw, a block, and a cylindrical rod with a conical head arranged from top to bottom; the screw is connected to the first locking member;

[0026] The stop pin has a C-shaped structure, and a U-shaped hole is provided on the upper horizontal plate of the stop pin;

[0027] The first limiting plate is a T-shaped structure, including a first limiting horizontal plate and a first limiting vertical plate arranged vertically. The first limiting vertical plate is arranged between the two first side plates. The two ends of the first limiting horizontal plate overlap the upper surface of the uppermost first transverse reinforcing member, and the two ends of the first limiting horizontal plate are provided with first positioning holes.

[0028] Circular positioning holes are provided on the upper surface of the left and right ends of the first transverse reinforcement at the topmost sides of the first leaching section, for installing the first limiting assembly and the second leaching section. The first limiting plate of the first limiting assembly has positioning holes of the same size. The first limiting plate spans the first housing assembly, and its flat lower surface is in contact with the upper surface of the first transverse reinforcement at the topmost side of the first housing assembly. The positioning holes on the first limiting plate are coaxially aligned with the positioning holes on the first transverse reinforcement at the topmost side of the first housing assembly. Then, the stop positioning pin is inserted through the positioning hole of the limiting assembly into the positioning hole of the first transverse reinforcement at the topmost side of the first housing assembly. The lower side of the limiting buckle is in contact with the lower surface of the first transverse reinforcement at the topmost side, and the upper surface is in contact with the upper surface of the middle square of the stop limiting pin. The U-shaped hole is passed through the threaded rod, and then the nut is tightened.

[0029] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: supports are provided at the four corners of the first leaching section.

[0030] To address the technical problem of how to implement the second housing assembly, this utility model adopts the following technical solution: the second housing assembly includes two second side plates, and a second reinforcing component is provided on the second side plates, including:

[0031] The second transverse reinforcement is disposed on the second side plate and is disposed along the length direction of the second side plate; the lower surface of the uppermost second transverse reinforcement is flush with the bottom of the second side plate, or the lower surface of the lowermost second transverse reinforcement is in contact with the bent edge of the second side plate.

[0032] The second vertical reinforcement is disposed between the adjacent second horizontal reinforcements.

[0033] This invention utilizes a second reinforcing component to ensure the strength of the second side plate, effectively guaranteeing the strength of the second leaching section.

[0034] To address the technical problem of deformation of the second shell assembly during transportation of the second leaching section, which is formed by welding together structural steel and sheet metal, this utility model adopts the following technical solution: a second limiting assembly is detachably installed on the second leaching section to prevent deformation of the second side plate of the second leaching section during transportation, including:

[0037] Threaded locating pins are installed on the lower left and right ends of the two lowest transverse reinforcing members at the front and rear of the second leaching section. The axis of the threaded locating pins is perpendicular to the lower plane of the lowest transverse reinforcing member. The position and size of the threaded locating pins are the same as the circular locating holes of the first leaching section. During manufacturing and transportation, the second limiting assembly is first assembled to the lower part of the second housing assembly. The circular holes at both ends of the second limiting plate of the second limiting assembly pass through the threaded locating holes. The protruding part of the second limiting plate, i.e., the second limiting vertical plate, is inserted upwards between the two second side plates of the second housing assembly. When the second limiting assembly is in contact with the lowest transverse reinforcing member, the threaded part of the threaded locating pin will protrude from the second limiting plate. Then, the nut is tightened onto the threaded locating pin. In this utility model, the second limiting plate in the second limiting assembly is installed between the two second side plates of the second housing assembly, thereby restricting the inward deformation of the second housing assembly.

[0051] 300 column assembly. Detailed Implementation

[0052] The present invention will be further described below with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the leaching section 10 includes a first leaching section 100, a second leaching section 200, and a positioning connection assembly.

[0054] like Figure 2-3As shown, the first leaching section 100 includes a first housing assembly 110, a first filter screen assembly 120, and a first oil hopper assembly 130.

[0055] In one embodiment, the first housing assembly 110 includes two first side plates 111. Reinforcing components are disposed on the first side plates 111; specifically, the first reinforcing components are welded to the outer side of the first side plates. The first reinforcing components include first transverse reinforcing members 112 and first vertical reinforcing members 113. Preferably, the first transverse reinforcing members are structural steel sections. In this embodiment, there are two first transverse reinforcing members 112; the upper first transverse reinforcing member 112 is preferably a square tube, and the lower first transverse reinforcing member 112 is preferably a channel steel. The two first transverse reinforcing members are attached to the first side plates from top to bottom. The first transverse reinforcing members 112 are disposed on the first side plates 111 and are arranged along the length direction of the first side plates 111.

[0056] In one embodiment, the upper surface of the uppermost first lateral stiffener 112 is flush with the upper edge of the first side plate 111. Specifically, the upper end of the first side plate of the first housing assembly is welded flush with the upper plane of the uppermost first lateral stiffener.

[0057] In another embodiment, the first side plate of the first housing assembly can also be bent and fitted to the upper surface of the uppermost first transverse reinforcement. Specifically, the top of the first side plate 111 is bent outward at 90°. The upper surface of the uppermost first transverse reinforcement 112 is fitted to the bent edge of the first side plate 111.

[0058] Preferably, the first vertical stiffener is a structural steel section. Several first vertical stiffeners connect the first horizontal stiffeners. Specifically, several first vertical stiffeners 113 are evenly distributed between adjacent first horizontal stiffeners 112.

[0059] A first filter screen assembly 120 and a first oil hopper assembly 130 are disposed on the first housing assembly 110. Specifically, the first filter assembly 120 is located between the two first side plates 111 and in the middle of the first side plates 111. The first side plate of the first housing assembly of the first leaching section is integrally connected to the straight section of the first oil hopper assembly.

[0060] The first oil hopper assembly is connected to the first shell assembly to form a whole. Therefore, when installing the first leaching section, the first shell assembly and the first oil hopper assembly are hoisted into place together. It is not necessary to lift the first oil hopper assemblies one by one after the first shell assembly is in place, so that the upper end of the first oil hopper assembly contacts the lower end of the first shell assembly before welding. The integral first leaching section is convenient to manufacture, transport and hoist, and it also eliminates the need to spend additional labor on the project site to complete the docking work between the first oil hopper assembly and the first shell assembly.

[0061] In one embodiment, a first limiting component 140 is detachably provided on the first leaching section 100 to prevent deformation of the first side plate of the first leaching section during transportation. Specifically, the first limiting component 140 includes a first limiting plate 141, a first limiting buckle 142, a stop limiting pin 143, and a first locking member 144.

[0062] In one embodiment, the first limiting plate 141 has a T-shaped structure, including a first limiting horizontal plate 1411 and a first limiting vertical plate 1412 arranged vertically. First positioning holes are provided at both ends of the first limiting horizontal plate 1411.

[0063] In one embodiment, the stop pin 143 includes a screw 1431, a block 1432, and a cylindrical guide rod 1433 with a tapered head, arranged from top to bottom; the screw is connected to the first locking member. Specifically, the stop pin has a block in the middle, a cylindrical guide rod with a tapered head at the lower end, and a threaded rod at the upper end.

[0064] In one embodiment, the first limiting buckle 142 has a C-shaped structure, and a U-shaped hole is provided on the upper horizontal plate of the first limiting buckle 142. The limiting buckle is C-shaped with a U-shaped hole on its upper side. The U-shaped hole is slightly larger than the diameter of the three-dimensional threaded rod at the upper end of the stop limiting pin. The lower side of the limiting buckle is in contact with the lower surface of the uppermost first transverse reinforcement, and the upper surface is in contact with the upper surface of the middle square of the stop limiting pin. The U-shaped hole passes through the threaded rod, and then the nut is tightened to ensure that the first side plate of the first housing assembly will not deform internally or externally.

[0065] The first limiting vertical plate 1412 is disposed between the two first side plates 111; the two ends of the first limiting horizontal plate 1411 overlap the upper surface of the uppermost first transverse reinforcement 112, and the first limiting plate 141 is restricted to the uppermost first transverse reinforcement 112 by the first limiting buckle 142, and is limited by the stop limiting pin 143, the lower end of the stop limiting pin 143 passes through the first limiting horizontal plate 1411 and the first transverse reinforcement in sequence; the upper end of the stop limiting pin is provided with a first locking member 144.

[0066] When installing this utility model, the first leaching section is hoisted and lowered onto the column. The first leaching section has a first limiting component. After the first leaching section is positioned, the second leaching section is installed. However, before installing the second leaching section, the first limiting component on the first leaching section needs to be removed. A positioning hole is opened on the upper surface of the first transverse reinforcement at the top of the first housing assembly. The first limiting plate of the first limiting component has a positioning hole of the same size. The first limiting plate spans the first housing assembly, and the lower surface of the first limiting plate is in contact with the upper surface of the first transverse reinforcement at the top of the first housing assembly. The positioning holes on the first limiting plate are coaxially aligned with the positioning holes on the first transverse reinforcement at the top of the first housing assembly. Then, the stop positioning pin is inserted through the positioning hole of the first limiting plate into the positioning hole of the first transverse reinforcement at the top of the first housing assembly.

[0067] In one embodiment, supports 150 are provided at the four corners of the first leaching section 100. Specifically, a pair of supports are respectively installed at the left and right ends of several connected first oil hopper assemblies of the first housing assembly, and the supports are welded to the first housing assembly to form a whole. The supports 150 are respectively connected to the upper first transverse reinforcement 112, the lower first transverse reinforcement and the first side plate 111.

[0068] The second leaching section 200 is installed above the first leaching section 100. For example... Figure 4-5 As shown, the second leaching section 200 includes a second housing assembly 210, a second filter screen assembly 220, a second oil hopper assembly 230, and a spray assembly 240.

[0069] In one embodiment, the second housing assembly 210 includes two second side plates 211. Second reinforcing components are disposed on the second side plates 211; specifically, the two second side plates of the second leaching section are welded with second reinforcing components. The second reinforcing components include second transverse reinforcing members 212 and second vertical reinforcing members 213. The second transverse reinforcing member 212 is preferably a structural steel section, and the second vertical reinforcing member 213 is preferably a structural steel section. The second reinforcing components are formed by several longitudinal structural steel sections arranged vertically between several transverse structural steel sections.

[0070] The second lateral reinforcement 212 is disposed on the second side plate 211 and is arranged along the length direction of the second side plate 211. In one embodiment, the lower surface of the uppermost second lateral reinforcement 212 is flush with the bottom of the second side plate 211. Specifically, the lower surface of the lowermost second lateral reinforcement at the lower end of the second side plate of the second housing assembly is flush with the bottom of the second side plate 211 and then welded. In another embodiment, the lower surface of the lowermost second lateral reinforcement 212 is abutted against the bent edge of the second side plate 211. Specifically, the side plate can also be bent and abutted against the lower surface of the lowermost second lateral reinforcement.

[0071] Second vertical reinforcements 213 are evenly distributed between adjacent second transverse reinforcements 212. The lower part of the second leaching section has second transverse reinforcements, and both the second transverse reinforcements and the second vertical reinforcements are located outside the side plate of the second leaching section and are welded to the side plate as a whole.

[0072] The second housing assembly 210 is provided with a second filter screen assembly 220, a second oil hopper assembly 230, and a spray assembly 240. Specifically, the second filter assembly 220 is located between the two second side plates 211 and in the middle of the second side plates 211. The second oil hopper assembly 230 is welded to the bottom of the two second side plates 211. The second oil hopper assembly 230, the second filter screen assembly 220, and the spray assembly 240 are installed between the two second side plates of the second housing assembly.

[0073] In one embodiment, a second limiting assembly 250 is detachably provided on the second leaching section 200 to prevent deformation of the second side plate of the second leaching section during transportation. Specifically, the second limiting assembly 250 includes a second limiting plate 251, a positioning pin 252, and a second locking member 253.

[0074] The second limiting plate 251 is installed between the two second side plates 211; the second limiting plate 211 is provided with second positioning holes. Specifically, the second limiting plate 251 has a T-shaped structure, including a vertically arranged second limiting horizontal plate 2511 and a second limiting vertical plate 2512. The two ends of the second limiting horizontal plate 2511 are provided with second positioning holes. The second limiting vertical plate 2512 is disposed between the two second side plates 211; the two ends of the second limiting horizontal plate 2511 overlap the upper surface of the lowermost second transverse reinforcing member 212.

[0075] A locating pin 252 is disposed on the lowest second transverse reinforcing member 212; the locating pin 252 passes through the second locating hole on the second limiting plate and is fitted with a second locking member 253. Specifically, the locating pin 252 passes through the second locating hole on the second limiting transverse plate 2511 and is fitted with the second locking member 253. The locating pin 252 is preferably a threaded locating pin. The second locking member 253 is preferably a nut.

[0076] A positioning connection assembly is provided on the second leaching section 200 and the first leaching section 100 to connect the first leaching section and the second leaching section. In one embodiment, the positioning connection assembly includes: first positioning holes provided at both ends of the uppermost first transverse reinforcing member 112; and positioning pins 252 provided in the first positioning holes to realize the connection between the first leaching section 100 and the second leaching section 200.

[0077] In one embodiment, the leaching section 10 includes a column assembly 300 comprising a plurality of columns, each column cooperating with a corresponding support 150 for supporting the first leaching section 100. Specifically, the support 150 rests on the column 401.

[0078] This utility model includes a first leaching section and a second leaching section. The first leaching section comprises a first oil hopper assembly, a first shell assembly, a first filter screen assembly, and a first limiting assembly. The second leaching section comprises a second shell assembly, a second filter screen assembly, a second oil hopper assembly, a spraying assembly, and a second limiting assembly.

[0079] After the first and second leaching sections arrive at the installation site, the first leaching section is first hoisted into place on the column at the construction site. At this point, it is not necessary to assemble the first oil hopper assembly separately. After the first leaching section is in place, the first limiting component is removed, and then the second limiting component on the second leaching section is removed, exposing the positioning holes on the upper surface of the first leaching section and the threaded positioning pins on the lower surface of the second leaching section. Then, the second leaching section is installed in place. After the front, back, left, and right threaded positioning pins at the bottom of the second leaching section correspond to the positioning holes at the top of the first leaching section, the lowermost second transverse reinforcement of the second leaching section is fitted with the uppermost first transverse reinforcement of the first leaching section (or the bent edge of the second side plate of the second leaching section is fitted with the bent edge of the first side plate of the first leaching section).

[0080] The assembly of the second leaching section with the first leaching section is carried out after the first leaching section is in place and the first limiting component is removed. Similarly, the second leaching section has a second limiting component at its lower part. To prevent the second leaching section from deforming during the process, its limiting pin is a positioning pin with its conical section facing downwards, which is welded to the second leaching section. The position of the positioning pin is the same as the position and size of the positioning hole on the first leaching section. When the second limiting component at the bottom of the second leaching section is removed, its several positioning pins will align with several positioning holes on the first leaching section. Each positioning pin corresponds to a relevant positioning hole, ensuring that the second leaching section can fall on the first leaching section with the correct size.

[0081] When the second leaching section and the first leaching section are combined into one unit, the second side plate of the second leaching section is aligned with the first side plate of the first leaching section and then the circumferential seam is welded.

[0082] This invention first installs the first leaching section in place, and then installs the second leaching section. The installation steps are simple, the installation positioning is fast, and no additional installation resources and time are required.
