Description

Technical Field

[0001] This utility model relates to the field of crude oil filtration technology, and more specifically, to a crude oil filtration mechanism. Background Technology

[0002] The raw material for carbon black oil is crude oil. Due to the complex composition of crude oil and the presence of a large number of impurities, it needs to be filtered during extraction. Because crude oil is viscous, the filter screen is easily clogged and needs to be replaced in time. In the existing technology, for example, the literature with application number CN201920389354.8, the filter screen is continuously tapped to avoid clogging. This method causes significant damage to the filter screen, and once damaged, replacement is cumbersome and affects production efficiency. Utility Model Content

The sealing ring is located between the filter screen frame and the oil pipeline; The clamping assembly presses the sealing ring tightly against the filter screen frame; The temporary storage chamber, located inside the filter frame, is used to store impurities.

[0005] Furthermore, a pair of flanges are provided, with a connecting rod on one side of the flange for connecting the flange, and a rotating shaft on the other side of the flange. A rotating platform is provided outside the rotating shaft, and a filter screen frame is installed on both sides of the rotating platform. A ring is provided at both ends of the filter screen frame.

[0006] Furthermore, the clamping assembly includes a positioning block mounted on the flange, with a threaded hole at the center of the positioning block and a threaded push rod inside the threaded hole. A rubber ring is installed on one side of the flange, and a second ring is installed at one end of the rubber ring. The sealing ring is fixedly connected to the second ring. Tightening the threaded push rod can drive the second ring to press against the first ring and compress the sealing ring.

[0007] Furthermore, a connecting ring is installed on one end of the inner side of the filter frame, and bolts are provided on the filter frame. The filter frame is fixedly connected to the connecting ring by the bolts.

[0008] Furthermore, the inner wall of the filter frame is smooth, and an L-shaped groove is provided on the inner wall of the filter frame. A locking block is provided on the outer ring of the filter body. The locking block moves from one end of the filter frame to the other end along the L-shaped groove. The filter frame can be screwed when it moves to the corner of the L-shaped groove.

[0009] The beneficial effects of this utility model are: by setting up a double filter frame, one for normal filtration and one for backup, the filter body can be replaced in time, avoiding clogging of the filter body; The clamping assembly allows for quick replacement of the filter body, effectively shortening replacement time and reducing the impact on production.

Detailed Implementation

[0011] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This application provides a crude oil filtration system; please refer to it. Figures 1-5 It includes oil pipeline 1, flange 2, and filter screen body 3, and also includes; The filter frame 4 is provided in pairs and can work alternately. The filter body 3 and the filter frame 4 are detachably connected. The sealing ring 5 is located between the filter frame 4 and the oil pipeline 1; The clamping component 6 presses the sealing ring 5 against the filter screen frame 4; Temporary storage chamber 7, located inside filter frame 4, is used to store impurities.

[0013] In practical applications, materials can flow through oil pipeline 1 to flange 2. The area between the two flanges 2 is the filtration station. When the material passes through the filter frame 4 and filter body 3, impurities in the material are intercepted. After a certain period of filtration, when replacement is needed, the filter body 3 is first installed into the spare filter frame 4. Then, the material transportation is temporarily stopped, and the clamping component 6 is manually released to separate the sealing ring 5 from the filter frame 4. Then, the filter frame 4 is rotated, and the spare filter frame 4 and filter body 3 are moved to the filtration station, while the original filter frame 4 and filter body 3 are moved out of the filtration station, achieving convenient replacement. Impurities in the temporary storage chamber 7 can be cleaned manually for the next replacement.

[0014] Reference Figure 1 , Figure 2 , Figure 3 Flange 2 is provided with a pair of connecting rods 21 on one side of flange 2. Connecting rods 21 are used to connect flange 2. A rotating shaft 22 is provided on the other side of flange 2. A rotating platform 23 is provided on the outside of the rotating shaft 22. Filter screen frame 4 is installed on both sides of rotating platform 23. Filter screen frame 4 is provided with rings 24 at both ends.

[0015] In practical applications, the connecting rod 21 makes the flange 2 a whole, the rotating shaft 22 provides support for the rotation of the filter frame 4 and the rotating table 23, and the ring 24 helps to increase the contact area with the sealing ring 5.

[0016] Reference Figure 1 , Figure 2 , Figure 3 The clamping assembly 6 includes a positioning block 25 mounted on the flange 2. The positioning block 25 has a threaded hole 26 at its center. A threaded push rod 27 is provided in the threaded hole 26. A rubber ring 28 is installed on one side of the flange 2. A second ring 29 is installed at one end of the rubber ring 28. The sealing ring 5 is fixedly connected to the second ring 29. Tightening the threaded push rod 27 can drive the second ring 29 to press against the first ring 24 and compress the sealing ring 5.

[0017] In practical applications, the rotation of the threaded push rod 27 can tighten the second ring 29 towards the first ring 24 and press the sealing ring 5. Manually rotating it in the opposite direction can release the second ring 29. The rubber ring 28 allows the second ring 29 to be in a movable state.

[0018] Example 1 of filter frame 4, refer to Figure 1 , Figure 2 , Figure 3 A connecting ring 411 is installed on one end of the inner side of the filter frame 4, and a bolt 412 is provided on the filter frame 4. The filter frame 4 is fixedly connected to the connecting ring 411 by the bolt 412.

[0019] In practical applications, the filter frame 4 and the filter body 3 can be fixed by bolt 412, but this connection method is relatively cumbersome.

[0020] Example 2 of filter frame 4, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The inner wall of the filter frame 4 is smooth, and the inner wall of the filter frame 4 is provided with an L-shaped groove 421. The outer ring of the filter body 3 is provided with a locking block 422. The locking block 422 moves from one end of the filter frame 4 to the other end along the L-shaped groove 421. The filter frame 4 can be rotated when it moves to the corner of the L-shaped groove 421.

[0021] In practical applications, the filter body 3 is held manually and the locking block 422 is aligned with the L-shaped groove 421. At this time, the filter body can be moved from one end of the filter frame 4 to the other end. Then, the filter body 3 is twisted to fix the filter body 3 in a fixed state. The material moves from left to right. Under the action of inertia, the filter body 3 cannot move from right to left on its own.
