Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum production, in particular to a fractionation tower for petroleum refining. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence. Petroleum is a viscous, dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons. Before it can be used, it must be processed to make petroleum products suitable for various purposes. Its common processing method is fractionation, and before using a fractionation tower to refine the petroleum, a filtering mechanism is usually set up to filter the crude oil to improve product quality. In real life, when filtering petroleum, in order to prevent debris in the petroleum from clogging the filter plate, a cleaning component is generally set up to clean the filter plate, but the existing cleaning component cannot discharge the cleaned debris, so that the cleaned debris will gather at the filter end. After working for a long time, the accumulated debris will affect its filtering effect.

[0003] A Chinese patent document (application publication number CN216890813U) discloses a fractionation tower for petroleum refining, which includes a bottom plate, on which a filter box, an oil pump, and a fractionation tower are installed from left to right, an evaporator is connected to the fractionation tower, a liquid extraction pipe of the oil pump extends into the filter box, a liquid outlet pipe of the oil pump is connected to the evaporator, and a liquid injection pipe is installed on the top surface of the filter box.

[0004] It can be seen that the patent document cited above also has the same problem. When the filter plate is cleaned by a cleaning brush, the cleaned debris cannot be discharged, so that the cleaned debris will accumulate at the filter end. After working for a long time, the accumulated debris will affect its filtering effect. Utility Model Content

[0005] The utility model aims to provide a fractionation tower for petroleum refining to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fractionation tower for petroleum refining, comprising a filter box for petroleum refining filtration, fixed grooves are provided on both sides of the filter box, filter plates are installed on the inner wall of the filter box, and retaining frames are installed on both sides of the filter box at the sides of the two fixed grooves, a motor is installed on one side of one of the retaining frames, a screw rod is installed on the output end of the motor, a scraper is mounted on the outer wall of the screw rod, and the bottom end of the scraper is in contact with the top end of the filter plate, a discharge groove is provided at the inner bottom end of the two retaining frames, and a collection box for collecting debris is provided at the bottom end of the two retaining frames.

[0007] As a preferred embodiment, connecting rods are installed on both sides of the collecting box, and elastic blocks are installed on opposite sides of the two connecting rods, and one end of the two elastic blocks is fixedly connected to the two sides of the material blocking frame respectively.

[0008] As a preferred embodiment, a feed port is provided at the top of the filter box, a liquid pump is installed at the bottom of one side of the filter box, and a discharge pipe of the liquid pump is connected to a distillation tower for petroleum refining.

[0011] As a preferred embodiment, a slide bar is commonly installed on the opposite sides of the two material blocking frames, and the outer wall of the slide bar passes through one side of the scraper.

[0012] As a preferred embodiment, positioning blocks are installed on both sides of the top end of the collecting box, and the two positioning blocks are respectively engaged with both sides of the bottom end of the material blocking frame.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The fractionation tower for petroleum refining benefits from the design of the motor, scraper, baffle frame and collection box. The motor drives the scraper to move through the screw rod, cleans the filter plate through the scraper and drives the cleaned debris to move, so that the debris is discharged from the discharge groove on the baffle frame and collected by the collection box. In this way, not only the debris on the filter plate can be cleaned, but also the cleaned debris can be discharged and collected, thereby ensuring the filtering effect of the filter plate;

[0015] By providing a collection box, an elastic block and a connecting rod, the elastic block is pressed inward until it is separated from the connecting rod, and then the collection box is moved downward to separate it from the material blocking frame. This method makes it easy to disassemble the collection box and facilitate subsequent processing of debris. BRIEF DESCRIPTION OF THE DRAWINGS
