Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, specifically to an oil-water separation device for petrochemical applications that is easy to clean. Background Technology

[0002] The petrochemical industry is a discipline that specializes in the study of materials such as petroleum and natural gas. It can reform and extract crude oil multiple times to produce a variety of raw materials such as benzene, ethylene, propylene, and naphthalene. It can also be further processed to produce formaldehyde, methanol, ethanol, phenol, and other substances.

[0003] The extracted crude oil has a high water content and contains impurities, so it needs to be separated into layers using an oil-water separator before being extracted and transported separately. However, ordinary such separators often use baffles to restrict the flow of crude oil slurry, but lack cleaning structures, and the surface is easily contaminated with dirt that is difficult to remove.

[0004] Now, a novel, easy-to-clean oil-water separation device for petrochemical applications is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an oil-water separation device for petrochemical applications that is easy to clean, in order to solve the problem of the inability to clean the baffle mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-clean oil-water separator for petrochemical use, comprising a tank and a feed trough. The feed trough is fixed to the upper right corner of the tank. A cover plate is snapped and fixed to the top of the tank, and a vertical frame is vertically installed at the center of the inside of the cover plate. Assembly slots are respectively provided on the front and rear sides inside the tank, and a partition is fixed between the assembly slots. Fixing blocks are respectively installed on the rear sides outside the tank, and a motor is installed at the bottom of the fixing blocks. A sleeve is movably connected to the top of the fixing blocks, and a lead screw is movably assembled in the sleeve. A balance block is fixed to the top of the lead screw, and limit rods are welded to the bottom sides of the balance block. A brush cylinder is horizontally assembled inside the limit rod. Two sets of round holes are respectively provided on the two sides inside the cover plate, and a slot is provided at the upper left corner of the tank.

[0007] As a further technical solution of this utility model, a water layer is stored at the bottom of the tank body, and a mixed liquid sedimentation layer is formed at the bottom of the water layer, while an oil layer floats at the top of the water layer.

[0008] As a further technical solution of this utility model, the upper part of the motor shaft is fixedly connected to the sleeve, and the limiting rod is embedded in the round hole.

[0009] As a further technical solution of this utility model, a through groove is provided at the upper part of the interior of the vertical frame, a slot is provided at the lower part of the interior of the vertical frame, and an insert plate is movably connected between the through groove and the slot. A bolt is installed in the hole at the top front end of the vertical frame, a liquid guide tube is fixed inside the insert plate, and a material pump is installed on the liquid guide tube.

[0010] As a further technical solution of this utility model, the insert plate can move vertically along the inner wall of the slot, and the bolt can abut against the insert plate in the vertical frame.

[0011] As a further technical solution of this utility model, the liquid guide tube moves to the right side of the vertical frame, and the liquid guide tube can be vertically raised and lowered in the through groove.

[0012] As a further technical solution of this utility model, a threaded groove is provided on the left side inside the cover plate, and a screw is movably connected in the threaded groove. A connecting block is movably installed at the bottom of the screw. A suction port is fixed on the left side of the bottom of the connecting block. A bent tube is fixed in the groove, and a flexible tube is connected between the bent tube and the connecting block.

[0013] As a further technical solution of this utility model, the left side of the connecting block slides against the inner wall of the tank, and the screw can rotate up and down along the inner wall of the threaded groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this easy-to-clean oil-water separation device for petrochemicals not only removes dirt from the surface of the baffle plate and adjusts the height of the pipeline during slurry transfer, but also achieves stratified discharge;

[0015] (1) By fixing partitions between the assembly slots, the petroleum slurry is injected into the tank through the pipeline from the feed chute on the right side. After the slurry comes into contact with the two sets of partitions, it will automatically separate into layers. The lighter layer floats on the surface as the oil layer, the heavier layer sinks to the bottom as the sediment layer, and the middle layer is the water layer. If the oil or sediment sticks to both sides of the partition, the motor is started and the sleeve is rotated at the top of the fixed block. Since the limit rods on both sides are embedded in the round holes, the screw can be vertically raised and lowered by rotating the sleeve, which forces the brush at the bottom of the limit rod to stick to both sides of the partition for cleaning, so as to avoid the partition being contaminated and affecting the subsequent separation work.

[0016] (2) By vertically installing a vertical frame at the center inside the cover plate, pulling out the insert plate at the vertical frame at the bottom of the cover plate and tightening it with bolts, the height of the insert plate can be adjusted at the slot so that the liquid guide tube can only move in the through groove, thereby achieving the purpose of changing the suction position according to different material layer thicknesses, avoiding the materials from mixing together again, and the material pump can be started to extract the material in layers.

[0017] (3) By installing a connecting block at the bottom of the screw, the screw in the threaded groove on the left side of the cover plate rotates up and down along the threaded groove, forcing the connecting block fixed to the screw to slide against the inner wall of the tank. Then, the height of the suction port is adjusted. With the connection of the hose, the external pump body can be connected to discharge materials at different liquid levels through the bend pipe. The intermediate transfer mechanism can ensure the quality of layered feeding. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides an embodiment of an easy-to-clean oil-water separator for petrochemical applications, comprising a tank body 1 and a feed trough 7. The feed trough 7 is fixed to the upper right corner of the tank body 1. A cover plate 8 is snapped and fixed to the top of the tank body 1, and a vertical frame 13 is vertically installed at the center of the inside of the cover plate 8. Assembly slots 12 are respectively provided on the front and rear sides inside the tank body 1, and a partition plate 4 is fixed between the assembly slots 12. Fixing blocks 23 are respectively installed on the rear sides outside the tank body 1, and a motor 24 is installed at the bottom of the fixing blocks 23. A sleeve 22 is movably connected to the top of the fixing blocks 23, and a lead screw 10 is movably assembled in the sleeve 22. A balance block 28 is fixed to the top of the lead screw 10, and limit rods 9 are welded to the bottom sides of the balance block 28. A brush cylinder 2 is horizontally assembled inside the limit rod 9. Two sets of round holes 11 are respectively provided on the sides inside the cover plate 8. A slot 17 is provided at the upper left corner of the tank body 1.

[0025] The lower part of the tank 1 contains a water layer 5, with a mixed liquid sedimentation layer 3 at the bottom and an oil layer 6 floating at the top.

[0026] The upper part of the rotating shaft of the motor 24 is fixedly connected to the sleeve 22, and the limiting rod 9 is embedded in the round hole 11.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, petroleum slurry is injected into tank 1 through a pipe from the feed trough 7 on the right. After the slurry comes into contact with the two sets of baffles 4, it will automatically separate into layers. The lighter layer floats on the surface as oil layer 6, the heavier layer sinks to the bottom as sediment layer 3, and the middle layer is water layer 5. If the oil or sediment sticks to both sides of the baffle 4, the motor 24 is started and the sleeve 22 is rotated at the top of the fixed block 23. Since the limiting rods 9 on both sides are embedded in the round holes 11, the vertical lifting screw 10 can be raised by rotating the sleeve 22, which forces the brush cylinder 2 at the bottom of the limiting rod 9 to stick to both sides of the baffle 4 for cleaning.

[0028] A through groove 27 is provided at the top inside the vertical frame 13, and a slot 30 is provided at the bottom inside the vertical frame 13. An insert plate 14 is movably connected between the through groove 27 and the slot 30. A bolt 15 is installed in the hole at the top front end of the vertical frame 13. A liquid guide tube 25 is fixed inside the insert plate 14, and a material pump 26 is installed on the liquid guide tube 25.

[0029] The insert plate 14 can move vertically along the inner wall of the slot 30, the bolt 15 can abut against the insert plate 14 in the vertical frame 13, the liquid guide tube 25 moves along the right side of the vertical frame 13, and the liquid guide tube 25 can move vertically up and down in the through groove 27.

[0030] Specifically, such as Figure 1 and Figure 3As shown, the insert plate 14 is pulled out at the vertical frame 13 at the bottom of the cover plate 8 and tightened with bolts 15. The height of the insert plate 14 can be adjusted at the slot 30 so that the liquid guide tube 25 can only move in the through groove 27, so as to change the suction position according to different material layer thicknesses and avoid the materials from mixing together again.

[0031] A threaded groove 29 is provided on the left side inside the cover plate 8, and a screw 16 is movably connected in the threaded groove 29. A connecting block 20 is movably installed at the bottom of the screw 16. A suction port 21 is fixed on the left side of the bottom of the connecting block 20. A bent pipe 18 is fixed in the slot 17, and a flexible hose 19 is connected between the bent pipe 18 and the connecting block 20. The left side of the connecting block 20 slides against the inner wall of the tank 1, and the screw 16 can rotate up and down along the inner wall of the threaded groove 29.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the screw 16 in the rotating threaded groove 29 on the left side of the cover plate 8 rotates up and down along the threaded groove 29, forcing the connecting block 20 fixed to the screw 16 to slide against the inner wall of the tank 1. Then, the height of the suction port 21 is adjusted. With the connection of the hose 19, the external pump body can be connected and materials at different liquid levels can be discharged through the bend pipe 18.

[0033] Working Principle: In use, this invention first injects petroleum slurry into the tank 1 through a pipe from the feed chute 7 on the right side. After contacting the two sets of baffles 4, the slurry automatically separates into layers: the lighter layer floats on the surface as the oil layer 6, the heavier layer sinks to the bottom as the sediment layer 3, and the middle layer is the water layer 5. If the oil or sediment adheres to both sides of the baffles 4, the motor 24 is activated, rotating the sleeve 22 at the top of the fixing block 23. Because the limiting rods 9 on both sides are embedded in the round holes 11, the rotation of the sleeve 22 vertically raises the screw 10, forcing the brush cylinder 2 at the bottom of the limiting rod 9 to adhere to both sides of the baffles 4 for cleaning. Then... Pull out the insert plate 14 at the bottom vertical frame 13 of the cover plate 8 and tighten it with bolts 15. The height of the insert plate 14 can be adjusted at the slot 30 so that the liquid guide tube 25 can only move in the through groove 27, so as to change the suction position according to different material layer thicknesses. Finally, rotate the screw 16 in the threaded groove 29 on the left side of the cover plate 8 so that the screw 16 rotates up and down along the threaded groove 29, forcing the connecting block 20 fixed to the screw 16 to slide against the inner wall of the tank 1. Then adjust the height of the suction port 21. With the connection of the hose 19, the external pump can be connected and the material at different liquid levels can be discharged through the bend pipe 18.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
