Description

Technical Field

[0001] This utility model belongs to the field of chemical analysis technology, and specifically relates to a chemical analysis impurity filter. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." It is found in parts of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is a primary target for geological exploration, and its derivative byproducts are diverse. During extraction, petroleum requires testing, but it contains numerous impurities. Therefore, filtration is necessary to reduce these impurities. However, existing impurity filters, when used for chemical analysis with small sample sizes (i.e., when the filter cartridge cannot be fully submerged), often only allow the sample to fall onto the bottom screen, leading to clogging and reduced filtration efficiency. Utility Model Content

[0003] This invention proposes a chemical analysis impurity filter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A chemical analysis impurity filter includes a cylindrical body, a cap fixed to the bottom of the cylindrical body, a head fixed to the top of the cylindrical body, a filter cartridge fixed inside the cylindrical body, a feed pipe centrally located at the upper end of the head, and a discharge pipe centrally located at the bottom of the cap. A distributing component is fixed inside the head, the distributing component includes a receiving bucket, the bottom of which is fixedly connected to a connecting rod. Several connecting holes are provided at the connection between the connecting rod and the receiving bucket. Two arc-shaped plates (first and second) are fixed on the connecting rod. The two arc-shaped plates (first and second) are fixed on the same horizontal plane, the included angle between the two arc-shaped plates (first and second) is 180°, the included angle between the two arc-shaped plates (second and third) is 180°, the included angle between adjacent arc-shaped plates (first and second) is 45°, and the upper surface of each arc-shaped plate is a quarter-circle arc.

[0006] Furthermore, the bottom of the connecting rod is provided with two arc-shaped plates, and the included angle between the two arc-shaped plates is 180°.

[0007] Furthermore, the cover is fixedly connected to the skirt support cylinder, and the bottom of the skirt support cylinder is fixedly connected to the base plate.

[0008] Furthermore, several reinforcing ribs are fixed at the connection between the skirt base and the base plate.

[0009] Furthermore, an inspection hole is provided on the side of the skirt base tube.

[0010] Furthermore, the side of the skirt support tube is also provided with an outlet pipe, the inner wall of the outlet pipe is fixedly connected to the support pipe, and the support pipe is fixedly connected to the discharge pipe.

[0011] Furthermore, a connecting pipe is provided at the center of the bottom of the cover, the end of the connecting pipe is fixedly connected to an elbow, and the end of the elbow is connected to a discharge pipe.

[0012] Furthermore, the filter cartridge includes a filter screen, an mounting plate is fixed to the upper end of the filter screen, the mounting plate is fixedly connected to a ring plate, and the ring plate is fixed to the inner wall of the cartridge.

[0013] Furthermore, the ring plate and the mounting plate are fixed together by connecting bolts.

[0014] This invention uses a feed pipe to enter the receiving bucket of the material distribution component. The material falls down the connecting rod through the connecting hole in the center of the receiving bucket. From the top view of the material distribution component, both the first and second arc-shaped plates are fan-shaped. The small radius of the fan-shaped plate is equal to the outer radius of the connecting rod, and the large radius of the fan-shaped plate is smaller than the inner radius of the filter screen of the filter cartridge. The central angle of the fan-shaped plate of the first arc-shaped plate and the fan-shaped plate of the second arc-shaped plate is 45°. The included angle between adjacent arc-shaped plates is 45°. Four slots are formed between adjacent arc-shaped plates. The angle between each slot is 45°. From the top view of the connecting rod, the third arc-shaped plate at the bottom of the connecting rod blocks two of the slots. The included angle between these two slots is 180°. From the top view of the connecting rod, two large fan-shaped plates with a central angle of 135° are formed. Two slots are formed between the two large fan-shaped plates. These two slots are the remaining slots after the four slots are blocked by the two arc-shaped plates. The chemical analysis sample is processed in several ways. A portion falls into the area of ​​arc-shaped plate one, where it undergoes projectile motion across a quarter-circle surface. Finally, it lands on the arc-shaped side of the filter cartridge for filtration. A large portion bypasses arc-shaped plate one through the grooves between the two plates and continues falling along the connecting rod. Another portion falls into the area of ​​arc-shaped plate two, where it undergoes projectile motion across a quarter-circle surface. Finally, it lands on the arc-shaped side of the filter cartridge for filtration. A further portion bypasses arc-shaped plate two through the grooves between the two plates and continues falling along the connecting rod. A third portion falls into the area of ​​arc-shaped plate three, where it undergoes projectile motion across a quarter-circle surface. Finally, it lands on the arc-shaped side of the filter cartridge for filtration. The last portion bypasses arc-shaped plate three through the grooves between the three plates and continues falling along the connecting rod, landing on the bottom filter screen of the filter cartridge for final filtration. This means that when there are few samples for chemical analysis, i.e., when the filter cartridge cannot be completely submerged, the samples will only fall onto the bottom filter screen for filtration, which can easily cause the bottom filter screen to become clogged and affect the filtration efficiency. By using arc-shaped plate one, arc-shaped plate two, arc-shaped plate three, and a trough, filtration can be carried out using multiple areas of the filter screen when there are few samples.

[0029] This utility model provides an embodiment, with reference to... Figure 1 The filter cartridge 18 includes a filter screen, with a mounting plate fixed to the upper end of the filter screen. The mounting plate is fixedly connected to a ring plate 11, which is fixed to the inner wall of the cartridge 8. The ring plate 11 and the mounting plate are fixed together by connecting bolts 12. This connection allows for a detachable connection of the filter cartridge 18. Several reinforcing ribs 10 are welded and fixed at the connection between the ring plate 11 and the inner wall of the cartridge 8, increasing the connection strength between them. A weighing cylinder 9 is fixed to the inner wall of the cartridge 8, and is fixedly connected to the ring plate 11. Several reinforcing ribs 10 are also fixed at the connection between the weighing cylinder 9 and the ring plate 11.

[0030] A buffer ramp 2407 is provided at the bottom of the connecting hole 2406. The buffer ramp 2407 enables a smooth transition between the connecting hole 2406 and the connecting rod 2402, reducing sample splashing.

[0031] In use, the chemical analysis sample enters the filter through the feed pipe 15 and then flows into the receiving bucket 2401 of the distribution component 24. The sample then falls downwards along the connecting rod 2402 from the connecting hole 2406 in the center of the receiving bucket 2401. From a top view of the distribution component 24, both the first arc plate 2403 and the second arc plate 2404 are fan-shaped. The small radius of the fan-shaped ring is equal to the outer radius of the connecting rod 2402, and the large radius is smaller than the inner radius of the filter screen of the filter cylinder 18. The central angle of the fan-shaped rings of the first arc plate 2403 and the second arc plate 2404 is 45°. The clamping distance between adjacent arc plates 2403 and 2404 is... Four slots 2408 are formed between adjacent arc-shaped plates 2403 and 2404 at an angle of 45°. The angle between each slot 2408 is 45 degrees. From the top view of the connecting rod 2402, the arc-shaped plate 2405 at the bottom of the connecting rod 2402 blocks two of the slots 2408. The included angle between the two slots 2408 is 180°. From the top view of the connecting rod 2402, two large fan rings with a central angle of 135° are formed. Two slots 2408 are formed between the two large fan rings. These two slots 2408 are the remaining slots 2408 after the four slots 2408 are blocked by the two arc-shaped plates 2405. The chemical analysis sample, in part, falls into the area of ​​the first arc plate 2403. On the first arc plate 2403, the sample undergoes projectile motion across its quarter-circular arc surface, and finally lands on the arc-shaped side of the filter cartridge 18 for filtration. A large portion passes through the groove 2408 between the first and second arc plates 2403, bypassing them and continuing to fall along the connecting rod 2402. Another portion falls into the area of ​​the second arc plate 2404. On the second arc plate 2404, the sample undergoes projectile motion across its quarter-circular arc surface, and finally lands on the arc-shaped side of the filter cartridge 18. The sample is filtered on the curved side surface. A portion of the sample passes through the groove 2408 between the two curved plates 2404, bypassing the two curved plates 2404 and continuing to fall along the connecting rod 2402. Another portion falls into the range of the three curved plates 2405. On the three curved plates 2405, the chemical analysis sample undergoes a projectile motion through the quarter-circle surface of the three curved plates 2405. Finally, the chemical analysis sample falls on the curved side surface of the filter cylinder 18 for filtration. The last portion passes through the groove 2408 between the three curved plates 2405, bypassing the three curved plates 2405 and continuing to fall along the connecting rod 2402. The chemical analysis sample falls on the bottom filter screen of the filter cylinder 18 for filtration.This means that when there are few samples for chemical analysis, i.e., when the filter cartridge 18 cannot be completely submerged, the samples will only fall onto the bottom filter screen for filtration, which will easily cause the bottom filter screen to become clogged and affect the filtration efficiency. By using the arc-shaped plate 2403, arc-shaped plate 2404, arc-shaped plate 2405, and trough 2408, filtration can be carried out using multiple areas of the filter screen when there are few samples.

[0032] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
