Description

Technical Field

[0001] This utility model relates to the field of waste residue filtration technology, specifically a waste residue filtration device for petrochemical plants. Background Technology

[0002] Petrochemical plants are industrial facilities that use petroleum or natural gas as raw materials to produce fuels such as gasoline, diesel, plastics, synthetic rubber, fertilizers, and chemical fibers through a series of chemical processing processes. They are the "blood production center" of modern industry, directly affecting multiple fields such as energy, transportation, agriculture, and daily necessities. Petrochemical plants are typical high-energy-consuming and high-polluting process industries. Their core processes, such as oil refining, cracking, and catalytic reforming, generate a large amount of solid waste residue.

[0003] Petrochemical plants generate large amounts of waste liquid containing solid waste during production. If this waste is discharged directly without effective treatment, it will not only cause environmental pollution but also waste recyclable resources. In current practical use, if the filter screen is difficult to disassemble, it may delay the catalyst recovery operation. The difficulty in disassembly and the resulting delay in cleaning will increase the probability of filter screen pore blockage. At the same time, if the waste cannot be discharged in time, it may accumulate on the filter screen and form blockage, leading to increased filtration resistance and an increased liquid content in the discharged waste.

[0024] 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.

[0025] Please see Figures 1-4 As shown, a waste residue filtration device for petrochemical plants includes a housing 1 and a feed pipe 2. The feed pipe 2 is connected to the inner wall of the housing 1, and a drive component 3 is provided on the outer side of the housing 1.

[0026] The feed pipe 2 provides space for waste to enter, and the drive unit 3 allows one end of the filter screen 6 to swing vertically, thereby improving the filtration speed and preventing clogging.

[0027] Connecting rod 4 is located on the outside of driving component 3, and connecting block 5 is rotatably connected to the top of connecting rod 4.

[0028] The connecting rod 4 can drive the connecting block 5 to move vertically, and the connecting block 5 drives one end of the filter screen 6 to move vertically, thereby facilitating the improvement of the filtration speed. At the same time, the vibration gradually discharges the waste residue from the surface of the filter screen 6.

[0029] The filter screen 6 is snapped onto the outside of the connecting block 5. The inner wall of the filter screen 6 is slidably connected to the fixing frame 7, and the outer side of the fixing frame 7 is slidably connected to the inner wall of the box 1.

[0030] The filter screen 6 can filter waste residue. When one end of the fixing frame 7 is separated from the limiting frame 8, it is only necessary to pull the U-shaped fixing frame 7 to pull out the other end of the fixing frame 7, which makes it easy to install and disassemble the filter screen 6.

[0031] The limiting frame 8 is slidably connected to the outside of the housing 1, and the outside of the limiting frame 8 is slidably connected to the inner wall of the fixing frame 7.

[0032] The limiting bracket 8 can limit the fixing bracket 7, thereby facilitating the limiting of the filter screen 6 and making it easier to disassemble and assemble the filter screen 6 when needed.

[0033] The bottom of the housing 1 is connected to a drain pipe 9, and a valve 10 is provided on the outside of the drain pipe 9 to control the opening and closing of the drain pipe 9.

[0034] The combined use of drain pipe 9 and valve 10 facilitates the collection and discharge of excess liquid from waste materials.

[0035] A fixing plate 11 is fixedly connected to the outer side of the housing 1, a filter frame 12 is slidably connected to the inner wall of the fixing plate 11, and a fixing frame 13 is fixedly connected to the inner wall of the fixing plate 11.

[0036] The fixing plate 11 can support the filter frame 12 and facilitate the sliding of the filter frame 12. The filter frame 12 can store the filtered waste residue. At the same time, the holes opened in the inner wall of the filter frame 12 can prevent liquid from being collected along with the waste residue, thus causing ineffective filtration. The fixing frame 13 can facilitate the collection of liquid falling from the filter frame 12.

[0037] Two sets of limiting rods 14 are slidably connected to the inner wall of the connecting block 5. A first spring 15 for limiting the two sets of limiting rods 14 is fixedly connected to the end of each set of limiting rods 14 near the inner wall of the connecting block 5. The end of the first spring 15 away from the limiting rod 14 is fixedly connected to the inner wall of the connecting block 5.

[0038] When the filter screen 6 needs to be disassembled, simply press the two sets of limiting rods 14. At this time, the limiting rods 14 compress the first spring 15 and disengage the filter screen 6 from the limiting position. When reinstalling, simply align the filter screen 6 with the inclined surface of the limiting rod 14 and push it horizontally. At this time, the filter screen 6 presses against the limiting rod 14 along the inclined surface of the limiting rod 14 and compresses the first spring 15. After reaching the appropriate position, the first spring 15 rebounds and pushes out the limiting rod 14 to re-limit the filter screen 6, thus completing the installation.

[0039] A second spring 16 is fixedly connected to the outer side of the box 1, and one end of the second spring 16 is fixedly connected to the outer side of the limiting frame 8. A guide plate 17 for guiding the waste residue is fixedly connected to the inner wall of the box 1.

[0040] The second spring 16 can limit the limit frame 8 to prevent the limit frame 8 from detaching from the fixed frame 7, thereby causing the filter screen 6 to fall off. The guide plate 17 can guide the waste residue falling from the filter screen 6.

[0041] A fixing post 18 and a mounting block 19 are fixedly connected to the outer side of the box body 1, and the inner wall of the fixing post 18 is slidably connected to one end of the limiting frame 8, and the inner wall of the mounting block 19 is slidably connected to the outer side of the limiting frame 8. A limiting block 20 is fixedly connected to the inner wall of the box body 1, and the inner wall of the limiting block 20 is slidably connected to the outer side of the connecting rod 4.

[0042] The fixed column 18 can limit the limit frame 8 to prevent it from shaking after the limit frame 8 is limited. The mounting block 19 can assist the limit frame 8 to slide, so as to facilitate the detachment and limitation of the fixed frame 7, and thus facilitate the installation and removal of the filter screen 6. The limiting block 20 can limit the connecting rod 4, thereby improving the stability of the connecting rod 4 when sliding.

[0043] The driving component 3 includes a motor 31 fixed to the outside of the housing 1. The output end of the motor 31 is fixedly connected to a fixing block 32, and the outside of the fixing block 32 is rotatably connected to the outside of the connecting rod 4 through a rotating shaft.

[0044] The motor 31 drives the fixed block 32 to rotate, and the rotation of the fixed block 32 drives the connecting rod 4 to move up and down, thereby driving the filter screen 6 to move up and down, so as to facilitate the discharge of waste residue from the surface of the filter screen 6.

[0045] Working principle: First, the waste residue is poured into the housing 1 through the feed pipe 2. The waste residue then falls onto the surface of the filter screen 6, where the solid waste residue separates from the liquid. Then, the motor 31 is started, which drives the fixed block 32 to rotate. The rotation of the fixed block 32 causes the connecting rod 4 to move up and down, thereby moving the filter screen 6 up and down. This facilitates the discharge of waste residue from the surface of the filter screen 6 and prevents the surface of the waste residue from still carrying a large amount of liquid. The filtered waste residue is then guided by the guide plate 17 and falls into the filter frame 12. After the excess liquid is drained in the filter frame 12, the waste residue can be poured out. When it is necessary to disassemble the filter screen 6, simply press the two sets of limit rods 14. The limit rods 14 compress the first spring 15 and disengage the filter screen 6 from the limit. At this time, the other end of the filter screen 6 can be disassembled. Then, pull the limit frame 8. The limiting bracket 8 slides along the mounting block 19, and at the same time, the limiting bracket 8 stretches the second spring 16, causing the limiting bracket 8 to disengage from the fixing post 18. At this time, pulling the fixing bracket 7 to disengage from the limiting bracket 8 completes the disassembly of the filter screen 6. During installation, simply align the filter screen 6 with the inclined surface of the limiting rod 14 and push it horizontally. At this time, the filter screen 6 presses against the limiting rod 14 along the inclined surface of the limiting rod 14 while compressing the first spring 15. After reaching the appropriate position, the first spring 15 rebounds and pushes out the limiting rod 14, re-limiting the filter screen 6 to complete the installation. When installing the other end of the filter screen 6, first insert the fixing bracket 7 through the filter screen 6 into the housing 1, and then release the pulled limiting bracket 8. At this time, the second spring 16 rebounds and drives the limiting bracket 8 to slide, thereby limiting the fixing bracket 7 and then limiting the filter screen 6, thus completing the installation.
