Description

Technical Field

[0001] This utility model relates to the field of petrochemical production, specifically a filter for petrochemical production processes. Background Technology

[0002] In the petrochemical production process, pipeline filtration devices are needed to remove solid impurities, broken rocks, and gravel from crude oil and refined oil. These devices are typically installed at wellheads, pumping stations, and oil production stations to ensure the quality of the oil and the safety of the production equipment.

[0003] When filtering oil, impurities are filtered out and trapped inside the filter. These impurities need to be cleaned regularly, otherwise they will affect the filtration. However, currently, cleaning impurities requires shutting off the oil supply in the pipeline before cleaning can begin. This interrupts the oil supply and requires waiting for the residual oil in the pipeline to be removed, which takes a lot of time, reduces production efficiency, and also affects the production efficiency of subsequent production units.

[0004] Therefore, a filter for petrochemical production processes is proposed to address the above problems. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the problem that the oil transported in the pipeline needs to be shut off before impurities can be cleaned, which would lead to the interruption of oil transport and the need to wait for the residual oil in the pipeline to be transported away, resulting in a lot of time consumption, reduced production efficiency, and also affecting the production efficiency of subsequent production equipment, this utility model proposes a petrochemical production process filter.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A petrochemical production process filter of this utility model includes an installation pipe, an inlet pipe fixedly connected inside the installation pipe, an outlet pipe fixedly connected inside the installation pipe, and a retention component provided inside the installation pipe. The retention component includes a working cylinder slidably connected inside the installation pipe. A first filter screen is fixedly connected inside the working cylinder. The first filter screen has a liquid inlet at a relative position. Two second filter screens are fixedly connected inside the working cylinder and are arranged opposite to each other.

[0007] Preferably, a lifting assembly is provided at the top of the working cylinder. The lifting assembly includes a screw fixedly connected to the top of the working cylinder. The screw passes through the installation pipe and is rotatably connected. A screw cylinder is rotatably connected to the top of the installation pipe. The inside of the screw cylinder is threadedly connected to the outside of the screw. A knob is fixedly connected to the outside of the screw cylinder.

[0008] Preferably, the working cylinder is provided with a cleaning assembly, which includes a lifting plate slidably connected to the inside of the working cylinder. The top of the lifting plate is fixedly connected to four connecting rods, which are divided into two groups. The top of the two groups of connecting rods is fixedly connected to a handle.

[0009] Preferably, an auxiliary component is provided inside the inlet pipe, the auxiliary component including a connecting block rotatably connected to the inside of the inlet pipe, and a filter plate is fixedly connected to the end of the connecting block.

[0010] Preferably, the installation pipe has two outlets inside, which are arranged opposite to each other and are flush with the position of the first filter screen after it rises.

[0011] Preferably, the connecting rod passes through the working cylinder and is slidably connected, and the connecting rod passes through the installation pipe and is slidably connected.

[0012] Preferably, the connecting block penetrates into the pipe and is slidably connected, the outer side of the filter plate is slidably connected to the inside of the inlet pipe, the outer side of the filter plate is slidably connected to the inside of the installation pipe, and the outer side of the filter plate is slidably connected to the inside of the working cylinder.

[0013] Preferably, after the lifting plate rises, its top is flush with the bottom of the first filter screen, and its top is flush with the bottom of the discharge port inside the installation pipe.

[0014] The advantages of this utility model are:

[0015] 1. This utility model transmits oil through an inlet pipe to the inside of a working cylinder, where it is filtered by a first filter screen. After filtration, impurities fall to the bottom of the working cylinder's inner cavity. When a certain amount of impurities is collected, the working cylinder can be pulled up, causing the impurities to rise and allowing a second filter screen to move to the end of the inlet pipe. This allows for further filtration of the transmitted oil, while impurities are blocked inside the inlet pipe. This process of filtering during oil transmission removes impurities, eliminating the need to stop oil transmission and thus improving production efficiency. It can also enhance the production efficiency of subsequent production equipment.

[0016] 2. This utility model uses a handle to move a connecting rod, which in turn raises the lifting plate, thereby raising the impurities so that their height is higher than the discharge port, making it easier to clean the impurities. Attached Figure Description

[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. Example 1

[0025] Please see Figure 1-4 As shown, a petrochemical production process filter includes an installation pipe 1, an inlet pipe 2 and an outlet pipe 3 fixedly connected inside the installation pipe 1, and a retention component inside the installation pipe 1. The retention component includes a working cylinder 4 slidably connected inside the installation pipe 1, a first filter screen 5 fixedly connected inside the working cylinder 4, an inlet opening at a relative position on the first filter screen 5, and two second filter screens 6 fixedly connected inside the working cylinder 4, the two second filter screens 6 being arranged opposite each other.

[0026] During operation, oil is transported to the working cylinder 4 through the inlet pipe 2, where it is filtered by the first filter screen 5. After filtration, impurities fall to the bottom of the working cylinder 4. When a certain amount of impurities is collected, the working cylinder 4 can be pulled up, causing the impurities to rise. This moves the second filter screen 6 to the end of the inlet pipe 2, where it can further filter the transported oil. Impurities are blocked inside the inlet pipe 2, thus cleaning them during oil transport. This eliminates the need to stop oil transport, improving production efficiency and also increasing the efficiency of subsequent production units.

[0027] The top of the working cylinder 4 is provided with a lifting component, which includes a screw 7 fixedly connected to the top of the working cylinder 4. The screw 7 passes through the installation pipe 1 and is rotatably connected. The top of the installation pipe 1 is rotatably connected to a screw cylinder 8. The inside of the screw cylinder 8 is threadedly connected to the outside of the screw 7. A knob 9 is fixedly connected to the outside of the screw cylinder 8.

[0028] During operation, rotating the knob 9 causes the screw barrel 8 to rotate, which in turn moves the screw 7, which in turn moves the working cylinder 4. This allows the position of the first filter screen 5 and the second filter screen 6 to be changed, and also moves the impurities, making it easier to clean them later.

[0029] The working cylinder 4 is equipped with a cleaning component, which includes a lifting plate 10 that is slidably connected inside the working cylinder 4. The top of the lifting plate 10 is fixedly connected to four connecting rods 11, which are divided into two groups. The top of the two groups of connecting rods 11 is fixedly connected to handles 12.

[0030] During operation, by pulling the handle 12, the connecting rod 11 is moved, which in turn raises the lifting plate 10, thereby raising the impurities so that the height of the impurities is higher than the discharge port, making it easier to clean the impurities.

[0031] The installation pipe 1 has two outlets inside, which are set opposite to each other and are flush with the position of the first filter screen 5 after it rises.

[0032] During operation, the movement range of the first filter screen 5 is limited by aligning it with the outlet, and the outlet is designed to facilitate the cleaning of impurities.

[0033] The connecting rod 11 passes through the working cylinder 4 and is slidably connected, and the connecting rod 11 passes through the installation pipe 1 and is slidably connected.

[0034] During operation, the connecting rod 11 is slidably connected to the working cylinder 4 and the installation pipe 1, so that the connecting rod 11 can smoothly drive the lifting plate 10 to move, thereby facilitating the movement of impurities and making it easier to clean them.

[0035] After the lifting plate 10 rises, its top is flush with the bottom of the first filter screen 5, and its top is flush with the bottom of the discharge port inside the installation pipe 1.

[0036] During operation, the lifting plate 10 rises to be flush with the first filter screen 5 and the bottom of the outlet, allowing impurities to be discharged smoothly from the outlet. Example 2

[0037] Please see Figure 5 As shown in the first embodiment, as another implementation of the present invention, an auxiliary component is provided inside the pipe 2. The auxiliary component includes a connecting block 13 rotatably connected inside the pipe 2, and a filter plate 14 is fixedly connected to the end of the connecting block 13.

[0038] During operation, the rising of the working cylinder 4 drives the filter plate 14 and the connecting block 13 to rotate, thereby moving the filter plate 14 into the inlet pipe 2 and sealing the inlet pipe 2. When filtering impurities, the impurities are left inside the inlet pipe 2, preventing them from being transported to other locations. This ensures that after the lifting plate 10 is raised, impurities will not enter the working cylinder 4, thus ensuring the cleanliness of the working cylinder 4.

[0039] Among them, the connecting block 13 passes through the inlet pipe 2 and is slidably connected; the outer side of the filter plate 14 is slidably connected to the inside of the inlet pipe 2; the outer side of the filter plate 14 is slidably connected to the inside of the installation pipe 1; and the outer side of the filter plate 14 is slidably connected to the inside of the working cylinder 4.

[0040] During operation, the impact of the oil allows the filter plate 14 to enter the working cylinder 4 without obstruction, thus allowing impurities to enter the working cylinder 4 smoothly.

[0041] The working principle is as follows: oil is transported to the working cylinder 4 through the pipeline 2, where it is filtered by the first filter screen 5. After filtration, impurities fall to the bottom of the working cylinder 4. When the amount of impurities reaches a certain level, the knob 9 can be turned to rotate the screw cylinder 8, which in turn moves the screw 7, thereby moving the working cylinder 4. This changes the position of the first filter screen 5 and the second filter screen 6, and also moves the impurities. Then, the handle 12 is pulled to move the connecting rod 11, which in turn raises the lifting plate 10, thus lifting the impurities for easy cleaning.
