Description

Technical Field

[0001] This invention relates to the field of filtration device technology, and more particularly to a raw material oil filtration device for chemical production. Background Technology

[0002] In chemical production processes, before the crude oil refining stage begins, a filtration device must be used to remove various impurities from the crude oil. This is because impurities in the crude oil will adversely affect the subsequent crude oil refining process. Specifically, the crude oil filtration device uses the principle of physical filtration to remove mechanical impurities contained in the oil, such as mud, sand, and iron filings.

[0003] However, existing crude oil filtration devices have many drawbacks. Their filter elements are fixedly installed inside the tank, which greatly complicates cleaning. Furthermore, the device relies solely on the gravity of the crude oil for filtration, resulting in a very slow filtration rate. Even more problematic is that once the filter element becomes clogged, the slow replacement process necessitates prolonged shutdowns for maintenance and repairs. Summary of the Invention

[0025] Example: A feedstock oil filtration device for chemical production, such as... Figures 1-9As shown, the device includes a tank body 1 and a tank cover 2. The tank cover 2 is bolted to the top of the tank body 1. It also includes a partition assembly, a filter assembly, and auxiliary components. The partition assembly is installed inside the tank body 1 to divide the internal space of the tank body 1. The partition assembly includes a notch plate 31, a fixed partition plate 32, a mounting base 33, a rotating shaft 331, a rotating partition plate 34, and a support plate 35. The notch plate 31 is welded to the inner wall of the middle section of the tank body 1. The fixed partition plate 32 is welded to the top of the notch plate 31. A mounting base 33 is welded to the middle of the bottom of the tank body 1. Mounting base 33, with a rotating shaft 331 rotatably connected thereto. A rotating partition plate 34 is welded and fixed to the top of the rotating shaft 331. Both the fixed partition plate 32 and the rotating partition plate 34 consist of a central column and three vertical plates evenly distributed radially on the side wall of the column. The included angle between any two adjacent vertical plates is 120 degrees. The notch edge of the notch plate 31 is fixedly connected to two vertical plates on the fixed partition plate 32. The notch plate 31, the fixed partition plate 32, and the side wall of the tank 1 form two receiving cavities for containing raw oil. Support plates 35 are welded and fixed to the outer edges of the three vertical plates of the partition 34. The support plates 35 are all in close contact with the inner wall of the tank body 1 to provide horizontal support for the rotating partition 34. A filter assembly for filtering raw oil is provided between the inner wall of the tank body 1 and the lower part of the notch plate 31. An auxiliary assembly is provided on the partition assembly to pressurize the partition assembly to assist in the filtration of raw oil. Three support legs 21 are welded and fixed circumferentially at intervals on the lower outer wall of the tank body 1. A valve pipe 22 is provided at the bottom of the tank body 1. The valve pipe 22 communicates with the internal space of the tank body 1 for... The liquid at the bottom of the tank 1 is drained. An exhaust pipe 23 is provided on the top left side of the tank cover 2. A lifting lug 24 is welded and fixed on the top right side of the tank cover 2 for lifting and moving the tank 1. An oil inlet pipe 25 is provided on the upper left side of the tank 1, which leads to the left accommodating cavity. An oil outlet pipe 26 is provided on the lower right side of the tank 1. The oil inlet pipe 25, the oil outlet pipe 26, and the exhaust pipe 23 are all connected to the internal space of the tank 1. The exhaust pipe 23 is used to discharge the gas carried in the raw oil injected into the tank 1 from the oil inlet pipe 25. A door panel 27 is rotatably provided on the upper rear side of the tank 1.

[0026] like Figure 4 and Figure 5 As shown, the partition assembly also includes ribs 36. Multiple ribs 36 are integrally and fixedly provided on the three vertical sidewalls of the rotating partition plate 34 at intervals. The ribs 36 are used to increase the structural strength of the rotating partition plate 34.

[0027] like Figure 4 , Figure 5 and Figure 6As shown, the filter assembly includes a hydraulic cylinder 41, a mounting ring 42, a filter element 43, a clamping plate 44, a horizontal plate 46, and a sealing ring 47. Hydraulic cylinders 41 are installed on the inner top of the three vertical plates of the rotating partition plate 34. The piston rod ends of the three hydraulic cylinders 41 are jointly fixed to the mounting ring 42 via flanges. Three sets of filter element groups are spaced apart on the mounting ring 42. Each set of filter element groups consists of three adjacent filter elements 43. Four clamping plates 44 are uniformly welded and fixed to the upper outer wall of each filter element 43. Four slots 45 are correspondingly opened at the connection between the mounting ring 42 and each filter element 43, corresponding to the clamping plates 44. A horizontal plate 46 is welded and fixed to the upper inner wall of each filter element 43. A sealing ring 47 is fixed to the top of each filter element 43 by screws. Three circular openings 48 are spaced apart on the right side of the notch plate 31, corresponding to the three filter elements 43 in the same group.

[0028] like Figure 4 and Figure 7 As shown, the auxiliary components include a mounting plate 51, a radar level gauge 52, an air pump 53, a connecting pipe 54, a solenoid valve 55, a motor 56, a long shaft 57, and a control panel 58. The mounting plate 51 is welded and fixed to the top right side of the fixed partition plate 32. The radar level gauge 52 is mounted on the right side of the mounting plate 51 via a flange. The acoustic wave emitting part of the radar level gauge 52 is located at the bottom of the mounting plate 51. The air pump 53 is bolted to the rear side of the mounting plate 51. A connecting pipe 54 is connected to the front side of the air pump 53. The end of the connecting pipe 54 away from the air pump 53 is fixedly connected to the mounting plate 51 via a flange, and the connecting pipe 54 communicates with the bottom space of the mounting plate 51. Four solenoid valves 55 are installed at intervals on the lower front side of the fixed partition plate 32. A motor 56 is installed on the top left side of the fixed plate 51. A long shaft 57 is installed through the middle of the fixed partition plate 32. The lower end of the long shaft 57 is inserted into the middle of the rotating partition plate 34 and fixedly connected to it by screws. The long shaft 57 is inserted into the middle of the rotating partition plate 34 to better transmit torque and prevent the long shaft from being twisted off. The upper end of the long shaft 57 is fixedly connected to the output shaft end of the motor 56 by a coupling. A control panel 58 is installed on the lower side of the outer wall of the tank body 1. The control panel 58 is electrically connected to the hydraulic cylinder 41, the radar level gauge 52, the air pump 53, the solenoid valves 55 and the motor 56 respectively.

[0029] The left-side receiving cavity, composed of the notch plate 31, the fixed partition plate 32, and the tank body 1, is receiving cavity a. The receiving cavity surrounded by the notch plate 31, the fixed partition plate 32, the side wall of the tank body 1, and the fixed plate 51 is receiving cavity b. Raw oil enters receiving cavity a through the inlet pipe 25. At this time, the operator simultaneously opens four solenoid valves 55 via the control panel 58. The raw oil flows from receiving cavity a through the solenoid valves 55 into receiving cavity b. Because the notch plate 31 at the bottom of receiving cavity b has three circular openings 48, and each circular opening 48 has a filter element 43 at its bottom, the raw oil in receiving cavity b flows downwards into these three filter elements 43. The filtered raw oil is filtered out from the outer surface of the filter element 43, falls into the bottom of the tank body 1, and is finally discharged through the outlet pipe 26. Because the filter element 43 filters… The filter element 43 has a small aperture, and the raw oil is filtered out by gravity alone, resulting in a slow filtration speed. This causes the raw oil to gradually accumulate in the receiving chamber b. When the radar level gauge 52 detects that the level of the raw oil in the receiving chamber b is the same as the height of the solenoid valve 55, the control panel 58 starts the air pump 53. The air pump 53 extracts air from the receiving chamber b through the connecting pipe 54, putting the receiving chamber b under negative pressure. This accelerates the flow of the raw oil from the receiving chamber a into the receiving chamber b, causing the level of the raw oil in the receiving chamber a to drop rapidly. When the radar level gauge 52 detects that the level of the raw oil in the receiving chamber b is high, it transmits a signal to the control panel 58. The control panel 58 then closes the four solenoid valves 55 and reverses the power supply to the air pump 53, allowing the air pump 53 to... Air is pumped into the receiving cavity b through the connecting pipe 54 to increase the air pressure in the receiving cavity b, thereby accelerating the speed at which the raw oil is filtered out from the filter element 43 and improving the filtration efficiency. At this time, the raw oil in the receiving cavity a gradually accumulates until the radar level gauge 52 detects that the level of the raw oil in the receiving cavity b is the same as the height of the solenoid valve 55. The above-mentioned air pumping and charging process is repeated, thereby greatly accelerating the filtration speed of the raw oil. When the radar level gauge 52 detects that the time required for the raw oil in the receiving cavity b to drop from the highest level to the lowest level exceeds the threshold, the filtration time becomes significantly longer, indicating that the three filter elements 43 located at the bottom of the receiving cavity b are blocked. At this time, the air pump 53 is in the state of charging the receiving cavity b, and the control panel 58 controls the air pump 53 to continue charging until the radar level gauge detects that the level of the raw oil in the receiving cavity b is the same as the height of the solenoid valve 55. The level gauge 52 detects that the liquid level in the receiving cavity b is lower than the top height of the filter element 43. The control panel 58 shuts off the air pump 53, keeps the four solenoid valves 55 closed, and simultaneously starts the three hydraulic cylinders 41. The piston rods of the three hydraulic cylinders 41 retract, causing the mounting ring 42 to move downward, which in turn moves the filter element 43 downward, separating it from the bottom of the notch plate 31. The control panel 58 then controls the motor 56 to start. The motor 56 drives the rotating partition plate 34 and the rotating shaft 331 to rotate counterclockwise by 120 degrees through the long shaft 57, causing the other set of three filter elements 43 located at the bottom of the receiving cavity a to rotate to the bottom of the receiving cavity b. The control panel 58 then starts the hydraulic cylinder 41, causing its piston rod to extend and push the mounting ring 42 upward again, causing the other set of three filter elements 43 to move upward.Furthermore, the sealing ring 47 at the top of the filter element 43 fits snugly against the bottom of the three circular openings 48 on the notch plate 31, achieving a seal. The initial steps are then repeated to continue filtering the raw oil. This allows for automatic and rapid replacement of the clogged filter element 43. The clogged filter element 43 is rotated to the rear of the tank 1. The operator opens the door panel 27, holds the horizontal plate 46, lifts the clogged filter element 43 upwards, and removes it for cleaning and maintenance.

[0030] like Figure 6 As shown, the upper corner of the mounting ring 42, where the slot 45 is located, is cut with an arc-shaped cut surface 6.

[0031] By setting the arc-shaped cut surface 6, when installing the filter element 43 into the mounting ring 42, the arc-shaped cut surface 6 can guide the clamping plate 44, so that the clamping plate 44 on the filter element 43 can be more easily inserted into the clamping groove 45, thereby facilitating the installation of the filter element 43.

[0032] like Figure 7 , Figure 8 and Figure 9 As shown, it also includes a bracket 71, an electric slide rail 72, a connecting block 73, a mounting plate 74, hooks 75, and a connecting rod 751. Three brackets 71 are welded and fixed at intervals from top to bottom on the rear side of the fixed partition plate 32. The electric slide rail 72 is installed on the three brackets 71. The connecting block 73 is fixedly connected to the slider of the electric slide rail 72. The mounting plate 74 is welded and fixed to the side of the connecting block 73 away from the electric slide rail 72. Two hooks 75 are slidably connected at intervals in the middle and on both sides of the mounting plate 74. A connecting rod 751 is welded and fixed between the tops of two adjacent hooks 75. The setting of the connecting rod 751 facilitates the synchronous sliding of two adjacent hooks 75. The control panel 58 is electrically connected to the electric slide rail 72.

[0033] When it is necessary to remove and clean the clogged filter element 43, the operator activates the electric slide rail 72 through the control panel 58. The electric slide rail 72 moves its slider downward, which in turn moves the connecting block 73 and the mounting plate 74 downward, so that the hook 75 is located on the side of the horizontal plate 46. The operator slides the hook 75 to the adjacent horizontal plate 46, so that the hook 75 is in a position that matches the adjacent horizontal plate 46. Then, the operator controls the electric slide rail 72 through the control panel 58 to move its slider upward, so that the hook 75 lifts the filter element 43 upward through the horizontal plate 46. The operator only needs to remove the filter element 43 from the hook 75, which saves time and effort.

[0034] It also includes rubber blocks 8, with each hook 75 having a rubber block 8 embedded and bonded to the side wall that is in contact with the mounting plate 74.

[0035] By setting rubber blocks 8, the friction between the hook 75 and the mounting plate 74 is increased, so that the hook 75 will not slide at will, and the hook 75 will not collide with the horizontal plate 46 when the mounting plate 74 moves downward, or slide away from the position of the hook 75 that matches the horizontal plate 46 when the hook moves upward.

[0036] It also includes a positioning plate 9, with the bottom of each horizontal plate 46 integrally molded and fixedly provided with a positioning plate 9.

[0037] By setting the positioning plate 9, when the hook 75 lifts the filter element 43 upward through the horizontal plate 46, the positioning plate 9 is located between two adjacent hooks 75, which prevents the horizontal plate 46 from sliding between the two adjacent hooks 75. At the same time, when installing the filter element 43, the filter element 43 can be positioned between the hooks 75, so that after the filter element 43 is lowered, its upper clamping plate 44 can be smoothly inserted into the matching groove 45.
