Description

Technical Field

[0001] This utility model relates to the field of crude oil sludge treatment technology, and in particular to a plate and frame filter press for crude oil sludge reduction treatment. Background Technology

[0002] Throughout the entire petroleum industry process, from dewaxing operations at crude oil wellheads to regular cleaning of refinery tanks, crude oil sludge is an unavoidable byproduct. It is a complex mixture of crude oil, sand, clay, and chemicals, containing not only petroleum pollutants but also potentially heavy metals and recalcitrant organic compounds. Given the high pollution levels and potential resource value of crude oil sludge, its reduction has become a key task in the petroleum environmental protection field. Plate and frame filter presses, with their highly efficient solid-liquid separation capabilities, have become an important piece of equipment in crude oil sludge treatment processes.

[0003] Currently, when using plate and frame filter presses to reduce the volume of traditional crude oil sludge, the simple design of the filter plates and the conventional connection methods are prone to loosening and displacement under long-term high-pressure operation. This leads to increased gaps between the filter plates, causing crude oil sludge leakage, which not only wastes materials but also poses a pollution threat to the surrounding environment. Furthermore, the existing pressing system cannot ensure uniform pressure distribution across the entire filter surface, resulting in insufficient pressure in some areas. This prevents the water in the crude oil sludge from being fully squeezed out, affecting the quality of solid-liquid separation and making it difficult to meet the increasingly stringent requirements for crude oil sludge reduction. Therefore, we propose a plate and frame filter press for crude oil sludge reduction to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a plate and frame filter press for crude oil sludge reduction treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plate and frame filter press for reducing crude oil sludge includes a fixed plate and multiple plate and frame filter plates. The fixed plate is provided with a fixing mechanism to fix the multiple plate and frame filter plates.

[0007] The fixing mechanism includes multiple threaded rods rotatably connected to a fixing plate. Multiple support plates are fixedly installed on the outer wall of the fixing plate. Sliding holes are opened on the outer wall of the support plates. The outer wall of the threaded rod and the inner wall of the multiple sliding holes on the same side are slidably connected. Multiple fixing nuts are threaded onto the outer wall of the threaded rod. The same sealing plate is threaded onto the multiple threaded rods.

[0008] Preferably, an installation opening is provided on the outer wall of the plate and frame filter plate, and a filter screen is fixedly installed on the inner wall of the installation opening.

[0009] Preferably, the outer wall of the sealing plate is provided with a first threaded hole that is adapted to the threaded rod, and the outer wall of the threaded rod and the inner wall of the first threaded hole are threadedly connected.

[0010] Preferably, two adjacent plate and frame filter plates are connected by a sealing mechanism. A U-shaped sealing groove is provided on one side of the plate and frame filter plate and on the outer wall of the sealing plate. A U-shaped sealing strip is fixedly installed on the other side of the plate and frame filter plate and on the outer wall of the fixing plate. The outer walls of adjacent U-shaped sealing strips and the inner walls of U-shaped sealing grooves are slidably connected.

[0011] Preferably, a reinforcing mechanism is provided on the outer wall of the fixed plate. The reinforcing mechanism includes a servo motor fixedly installed on the outer wall of the fixed plate. Two threaded rods on the same layer are connected by chain drive. Two rotating shafts are fixedly installed on the outer wall of the fixed plate. A first bevel gear is fixedly sleeved on the threaded rod. Two second bevel gears are fixedly sleeved on the rotating shaft. Adjacent first and second bevel gears are meshed and connected. A third bevel gear is fixedly sleeved on the outer wall of both the output shaft of the servo motor and the rotating shaft. Two bevel gears are meshed and connected.

[0012] Preferably, a chain disc adapted to the chain is fitted on the outer wall of each of the two threaded rods in the same layer.

[0013] Preferably, a plurality of mounting blocks are fixedly installed on the outer wall of the fixing plate, and the outer wall of the mounting block is provided with a rotating hole. The outer wall of the rotating shaft and the inner wall of the two rotating holes on the same side are rotatably connected.

[0014] The beneficial effects of this utility model are as follows:

The sealing mechanism's U-shaped sealing groove and U-shaped sealing strip cooperate to prevent crude oil sludge leakage. In the reinforcing mechanism, the servo motor drives the threaded rod to rotate synchronously through the chain and bevel gear, increasing the pressure on the plate and frame filter plate and making the pressure distribution uniform. Overall, this improves the efficiency and quality of crude oil sludge reduction treatment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 A plate and frame filter press for reducing crude oil sludge includes a fixed plate 1 and multiple plate and frame filter plates 2. The fixed plate 1 is provided with a fixing mechanism to fix the multiple plate and frame filter plates 2. The fixing mechanism includes multiple threaded rods 3 rotatably connected to the fixed plate 1. Multiple support plates 4 are fixedly installed on the outer wall of the fixed plate 1. Sliding holes 5 are opened on the outer wall of the support plates 4. The outer wall of the threaded rods 3 and the inner wall of the multiple sliding holes 5 on the same side are slidably connected. Multiple fixing nuts 6 are threadedly sleeved on the outer wall of the threaded rods 3. The same sealing plate 7 is threadedly connected to the multiple threaded rods 3.

[0022] To further explain, the multiple threaded rods 3 in the fixing mechanism are slidably connected to the sliding holes 5 of the support plate 4, and the multiple plate and frame filter plates 2 are stably fixed on the fixing plate 1 by the fixing nuts 6 and the sealing plate 7. This can effectively prevent the plate and frame filter plates 2 from shifting or loosening during the filter pressing process, ensuring the stability of the overall structure of the filter press and ensuring the normal operation of the filter pressing.

[0023] To further explain, the use of threaded connection, by tightening the fixing nut 6 and the sealing plate 7, facilitates the installation and disassembly of the original plate and frame filter plate 2, making subsequent maintenance, filter plate replacement and other operations easier.

[0024] like Figure 1 and Figure 2 As shown, an installation port 8 is provided on the outer side wall of the plate and frame filter plate 2, and a filter screen 9 is fixedly installed on the inner side wall of the installation port 8.

[0025] To further explain, the filter screen 9 can filter crude oil sludge, allowing the liquid to pass through the filter screen and be discharged while solid impurities are intercepted, thus achieving solid-liquid separation of crude oil sludge and achieving the purpose of volume reduction treatment.

[0026] like Figure 1As shown, a first threaded hole adapted to the threaded rod 3 is provided on the outer wall of the sealing plate 7, and the outer wall of the threaded rod 3 and the inner wall of the first threaded hole are threadedly connected.

[0027] To further explain, this design ensures a tight connection between the sealing plate 7 and the threaded rod 3, further enhancing the fixing effect on the plate and frame filter plate 2 and improving the sealing performance and stability of the plate and frame filter plate 2.

[0028] like Figure 1 and Figure 2 As shown, two adjacent plate and frame filter plates 2 are connected by a sealing mechanism. A U-shaped sealing groove 10 is provided on one side of the plate and frame filter plate 2 and on the outer wall of the sealing plate 7. A U-shaped sealing strip 11 is fixedly installed on the other side of the plate and frame filter plate 2 and on the outer wall of the fixing plate 1. The outer wall of the adjacent U-shaped sealing strip 11 and the inner wall of the U-shaped sealing groove 10 are slidably connected.

[0029] To further explain, the cooperation between the loop-shaped sealing groove 10 and the loop-shaped sealing strip 11 in the sealing mechanism enables a good sealing structure to be formed between adjacent plate and frame filter plates 2 and between the plate and frame filter plates 2 and the fixed plate 1 and the sealing plate 7, preventing the leakage of crude oil sludge during the pressure filtration process and improving the pressure filtration efficiency and effect.

[0030] like Figure 1 and Figure 3 As shown, a reinforcing mechanism is provided on the outer wall of the fixed plate 1. The reinforcing mechanism includes a servo motor 12 fixedly installed on the outer wall of the fixed plate 1. Two threaded rods 3 on the same layer are connected by a chain 13. Two rotating shafts 14 are fixedly installed on the outer wall of the fixed plate 1. A first bevel gear is fixedly sleeved on the threaded rod 3. Two second bevel gears are fixedly sleeved on the rotating shaft 14. Adjacent first bevel gears and second bevel gears are meshed. A third bevel gear is fixedly sleeved on both the output shaft of the servo motor 12 and the outer wall of the rotating shaft 14. The two bevel gears are meshed.

[0031] To further explain, the servo motor 12 in the strengthening mechanism drives the rotating shaft 14 to rotate through the third bevel gear. The second bevel gear on the rotating shaft 14 meshes with the first bevel gear on the threaded rod 3. The two threaded rods 3 on the same layer are connected by the chain 13, realizing the synchronous rotation of multiple threaded rods 3. This can provide more powerful force, so that the sealing plate 7 applies more uniform and stable pressure to the plate and frame filter plate 2, thereby enhancing the filtration effect and structural strength of the filter press.

[0032] To further explain, the use of servo motor 12 can realize the automated operation of the filter press, reduce manual intervention, and improve work efficiency and operational accuracy.

[0033] like Figure 3As shown, the outer walls of the two threaded rods 3 on the same layer are fitted with chain discs that are compatible with the chain 13.

[0034] To further explain, the chain disc ensures the stability and reliability of the chain 13 transmission, effectively transmits power to each threaded rod 3, ensures that multiple threaded rods 3 rotate synchronously, and makes the pressure of the sealing plate 7 on the plate frame filter plate 2 evenly distributed.

[0035] like Figure 1 and Figure 3 As shown, multiple mounting blocks 15 are fixedly installed on the outer wall of the fixing plate 1. Rotation holes are provided on the outer wall of the mounting block 15. The outer wall of the rotating shaft 14 and the inner walls of the two rotation holes on the same side are rotatably connected.

[0036] To further explain, the rotating hole provides stable support and rotation space for the rotating shaft 14, ensuring the smooth rotation of the rotating shaft 14, thereby ensuring the normal operation of the entire reinforcing mechanism and improving the working stability and reliability of the filter press.

[0037] The functional principle of this utility model can be explained through the following operation methods:

[0038] Install plate and frame filter plate 2

[0039] First, install the first plate and frame filter plate 2 onto multiple threaded rods 3, allowing the threaded rods 3 to slide on the support plate 4. Then, screw the fixing nut 6 onto the threaded rod 3. Repeat the above process to install another plate and frame filter plate 2 and fixing nut 6. Finally, install the sealing plate 7 onto multiple threaded rods 3 until all plate and frame filter plates 2 and fixing nuts 6 are installed. This arranges multiple plate and frame filter plates 2 sequentially between the fixing plate 1 and the sealing plate 7. Note that the U-shaped sealing groove 10 on the plate and frame filter plate 2 corresponds and matches the U-shaped sealing strip 11 on the adjacent plate and frame filter plate 2, fixing plate 1, or sealing plate 7 to ensure good sealing and that the threaded rods 3 can slide smoothly without interfering with other components.

[0040] Fixed plate 1 frame filter plate

[0041] Initially tighten the fixing nut 6 to initially fix the plate and frame filter plate 2 between the fixing plate 1 and the sealing plate 7, but do not tighten it at this time to facilitate subsequent adjustment. Use the first threaded hole on the sealing plate 7 to connect the sealing plate 7 to the threaded rod 3. Then gradually tighten the sealing plate 7 while adjusting the fixing nut 6 to firmly fix the multiple plate and frame filter plates 2. During the tightening process, ensure that the tightening degree of each nut and the sealing plate 7 is uniform to prevent uneven force on the plate and frame filter plates 2.

[0042] Initiate strengthening of agencies

[0043] When the servo motor 12 is turned on, the third bevel gear on the output shaft of the servo motor 12 drives the third bevel gear on the rotating shaft 14 that meshes with it to rotate, thereby causing the rotating shaft 14 to start rotating.

[0044] The second bevel gear on the rotating shaft 14 meshes with the first bevel gear on the threaded rod 3, driving the threaded rod 3 to rotate. Since the two threaded rods 3 on the same layer are connected by the chain 13, multiple threaded rods 3 will rotate synchronously.

[0045] As the threaded rod 3 rotates, the sealing plate 7 moves on the threaded rod 3, further applying pressure to the plate and frame filter plate 2, thereby enhancing the overall structural strength and sealing performance of the filter press.

[0046] Perform pressure filtration operation

[0047] The crude oil sludge to be treated is introduced into the filter press through a suitable inlet, entering the chamber of the plate and frame filter plate 2. Under pressure, the liquid in the crude oil sludge passes through the filter screen 9 inside the mounting port 8 on the plate and frame filter plate 2, achieving solid-liquid separation. The liquid is discharged from the drain port of the filter press, while solid impurities are trapped inside the plate and frame filter plate 2.

[0048] Cleaning and maintenance

[0049] After the filter press is completed, turn off the servo motor 12 to stop applying pressure to the plate and frame filter plate 2, loosen the fixing nut 6 and the sealing plate 7, remove the plate and frame filter plate 2 from the threaded rod 3, clean the solid impurities and filter screen 9 remaining on the plate and frame filter plate 2, check whether the filter screen 9 is damaged, and replace it in time if it is damaged.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
