Description

Technical Field

[0001] The invention relates to the technical field of filtering and separating devices, in particular to a high-pressure crude oil filtering separator with pressure self-adaptive regulation. Background Art

[0002] Oil is an important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and less pollution to the atmosphere after combustion. However, since oil is a fluid mineral buried deep underground, it easily forms a mixture of some mud and a small amount of impurities. This requires filtering the oil for better processing. Crude oil filters are mainly used to filter out larger particles of mud, fine stones and other impurities in crude oil, which plays a very important role in effectively protecting the normal operation of the pump.

[0003] When crude oil is fed into the filter separator, it usually needs to be pressurized by the pressurizing part, and then the impurity particles in the crude oil are filtered through the filtering structure. In this process, the long-term use of the filtering structure can easily lead to a decrease in the output efficiency of the crude oil. However, when the output efficiency of the crude oil becomes low, conventional separation equipment cannot determine whether the filtering structure is clogged or the crude oil residue is insufficient. If the filtering structure is clogged, it needs to be shut down for cleaning. If the crude oil residue is insufficient, pressurization is required to maintain the crude oil delivery efficiency. When the separation equipment is actually used, it cannot be adjusted according to the actual situation. Summary of the Invention

[0015] Beneficial effects of the present invention: 1. The present invention calculates the amount of crude oil delivered per unit time by the filter box that is initially used, and then switches to two groups of filter boxes for use. Each group delivers crude oil according to the same unit time, and the calculation and comparison are performed based on the amount of crude oil. First, the data of the two groups of filter boxes are compared, and then compared with the previous reference group. If there is a difference in the data of the two groups of filter boxes, it indicates that the filter structure in the filter box needs to be cleaned. If the data of the two groups of filter boxes are similar, but there is a difference with the control test, it indicates that the crude oil delivery efficiency has decreased, and the propeller rotation speed is increased to increase the pressure value.

[0016] 2. The present invention pushes the wrapping layer upward when the conical plate approaches the circular ring, and inserts the plug plate into the slot of the propeller. When the propeller rotates, it drives the vertical rod to rotate. Due to the connection between the turntable and the vertical rod, the first sweeping plate sweeps along the surface of the bottom plate, and cleans the impurities filtered in the bottom plate and the filter frame into the first circular frame. The second sweeping plate sweeps along the surface of the conical filter plate, and cleans the impurities on the surface of the conical filter plate and sends them into the second circular frame. The sealing block is manually pulled out by the pulling frame. As the sealing block moves, the pull rope pulls the scraper from both sides. The scraper cleans the inside of the first and second circular frames, and cleans the impurities inside the first and second circular frames out of the filter box.

[0017] 3. The present invention drives the screw to rotate through the first motor, and the screw block cooperates with the screw thread to move horizontally, driving the ring rope to move, and the piston plate moves along the inside of the diversion pipe to change the delivery direction of the crude oil. At the same time, the vertical plate drives the cross bar to move, and the two sealing plates move along the inside of the oil discharge pipe, opening the connection between one group of oil discharge pipes and the delivery pipe, and cutting off the connection between the other group of oil discharge pipes and the delivery pipe. The cut-off group is isolated from the filter box and the separator. At the same time, as the sealing plate moves, the second connecting rod and the first connecting rod cooperate to push the vertical rod upward, and the bottom plate moves upward along the top of the drain frame to clean the inner wall of the drain frame.

[0018] 4. When the present invention determines that the crude oil residue is insufficient, the second motor drives the speed change gear box and the shaft to rotate faster. Through the transmission cooperation of the first bevel gear and the second bevel gear, the propeller accelerates the suction of crude oil into the filter box, thereby increasing the crude oil entry rate and maintaining stable crude oil output. The two sets of propellers connected to the shaft are used to suck the crude oil, and the other set is used to clean the filter frame and conical filter plate, thereby maintaining the permeability of the filter structure.

[0019] 5. Compared with the prior art, the present invention alternately feeds crude oil into two sets of filter boxes through diversion pipes, and filters and separates the crude oil through the filter frames and conical filter plates inside the filter boxes. The crude oil output efficiency at the bottom of the filter boxes is compared to distinguish between insufficient crude oil or clogged filter structures. The filter structure is cleaned or the propeller speed is increased as needed to increase the pressure and speed up the crude oil passage rate. BRIEF DESCRIPTION OF THE DRAWINGS

A sealing plate 24 is slidably installed inside the oil drain pipe 21. The sealing plate 24 penetrates into the filter box 2 and is fixed with a second connecting rod 219. The other end of the second connecting rod 219 is rotatably installed with the first connecting rod 218 through a rotating shaft. The other end of the first connecting rod 218 is rotatably connected to the bottom of the vertical rod 217 through a universal joint. The driving assembly 4 also includes a vertical plate 46. The bottom of the screw block 44 is fixed with a vertical plate 46, and the bottom of the vertical plate 46 is fixed with a cross bar 47. The two ends of the cross bar 47 are fixedly connected to the two sealing plates 24. The first motor 43 drives the screw 42 to rotate, and the screw block 44 and the screw 42 are threaded together horizontally. The piston plate 12 moves along the inside of the diverter pipe 1, changing the delivery direction of the crude oil. At the same time, the vertical plate 46 drives the cross bar 47 to move. The two sealing plates 24 move along the inside of the oil discharge pipe 21, opening the connection between one set of oil discharge pipes 21 and the delivery pipe 31, and cutting off the connection between the other set of oil discharge pipes 21 and the delivery pipe 31.

First, the data of the two groups of filter boxes 2 are compared, and then compared with the previous reference group. If there is a difference in the data of the two groups of filter boxes 2, it means that the filter structure in the filter box 2 needs to be cleaned. If the data of the two groups of filter boxes 2 are similar, but there is a gap with the control test, it means that the crude oil delivery efficiency has become low, and the rotation speed of the propeller 210 is accelerated to increase the pressure value. The first motor 43 drives the screw 42 to rotate, and the screw block 44 and the screw 42 thread cooperate to move horizontally, driving the ring rope 45 to move, and the piston plate 12 moves along The diverter pipe 1 moves inside to change the delivery direction of crude oil.
