Description

Technical Field

[0001] The invention relates to the technical field of petroleum filtering, in particular to a petroleum filtering device. Background Art

[0002] In the process of oil extraction and processing, oil filtration is a crucial link, which aims to remove impurities in oil to improve the quality and purity of oil. Most traditional oil filtration devices use static filtration, that is, oil is filtered through a fixed filter. However, this static filtration method has some problems, such as low filtration efficiency, easy clogging of the filter, and difficulty in effectively removing fine impurities.

[0003] In order to solve the above problems, people began to explore dynamic filtration technology, in which a mechanical device is used to drive the filter to move in order to improve the filtration efficiency and cleanliness. Although some existing dynamic filtration devices have improved the filtration effect to a certain extent, they still have shortcomings. For example, some devices cannot effectively separate oil with different impurity contents during the filtration process, resulting in difficulties in subsequent treatment; other devices have poor cleaning ability for impurities adhering to the filter, and the filtration efficiency decreases significantly after long-term use. Summary of the invention

[0004] In view of the above-mentioned prior art, the present invention provides a petroleum filtering device, which can separate three kinds of petroleum with different impurity contents during filtration and improve the cleaning ability of the filter.

[0005] To achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows:

[0006] A petroleum filtering device comprises a shell and a first sprocket, a second sprocket, a transmission chain, a support plate and a filter screen arranged in the shell, wherein the side wall of the shell is connected to a feed pipe; a first discharge pipe is arranged on a side of the shell close to the first sprocket, a second discharge pipe is arranged on a side of the shell close to the second sprocket, and a third discharge pipe is arranged at the center of the bottom; the first sprocket and the second sprocket rotate under the drive of a driving mechanism, the diameter of the first sprocket is smaller than the diameter of the second sprocket, the transmission chain is wound around the first sprocket and the second sprocket, the transmission chain is provided with the support plate, adjacent support plates are connected by a flexible sealing belt, the support plate is provided with a through hole, and the filter screen is arranged in the through hole.

[0007] Furthermore, the outer shell includes a bottom plate, a side plate and a top plate, the bottom plate is connected to the side plate, the side plate is connected to the top plate, the side plate includes a first arc plate, a second arc plate and a straight plate, the first sprocket is located at an eccentric position of the first arc plate, the second sprocket is located at an eccentric position of the second arc plate, and the ends of the first arc plate and the second arc plate are connected through the straight plate.

[0008] Furthermore, the straight plate is provided with a channel connected to the feed pipe, the first arc plate is provided with a channel connected to the first discharge pipe, the second arc plate is provided with a channel connected to the second discharge pipe, and the bottom plate is provided with a channel connected to the third discharge pipe.

[0009] Furthermore, the top plate is detachably connected to the side plates, and the bottom plate is fixedly connected to the side plates.

[0010] Furthermore, a disc is provided above the first sprocket and the second sprocket, a shielding strip is provided between the first sprocket and the second sprocket, the shielding strip is tangent to the disc, the bottom of the shielding strip is connected to the partition, the third discharge pipe is connected from the bottom to the top of the partition, and an elastic sealing strip corresponding to the disc and the shielding strip is provided at the bottom of the support plate, and the sides of the sealing strip are abutted against each other.

[0011] Furthermore, the driving mechanism includes a motor, a first pulley, a second pulley and a transmission belt, the transmission ratio of the first pulley and the second pulley is equal to the transmission ratio of the first sprocket and the second sprocket, the first pulley and the second pulley are connected by a transmission belt, and the motor is connected to the first pulley or the second pulley.

[0013] Furthermore, a mounting plate is provided at the bottom of the supporting leg, and the motor is fixedly connected to the mounting plate.

[0014] The beneficial effect of the present invention is that: when filtering, the driving mechanism drives the filter screen to rotate. When rotating to the position of the first sprocket, due to the small diameter, the centrifugal force it receives is large, so most of the impurities on the filter screen are thrown out, thereby improving the cleaning ability of the filter screen, and forming a high impurity area on the side close to the first sprocket, and the oil in the high impurity area is discharged from the first discharge pipe. When the filter screen rotates to the position of the second sprocket, the filter screen is also affected by the centrifugal force, but the centrifugal force it receives is small, and a small number of large particles of impurities on the filter screen are thrown out, forming a low impurity area on the side close to the second sprocket, and the oil in the low impurity area is discharged from the second discharge pipe. The present invention can filter and intercept impurities in oil during filtering, and form three areas with different impurity contents, and these oils can be transported to subsequent processing devices for targeted processing, thereby improving the effect of oil filtering. In the process of filtering, the impurities attached to the filter screen can be separated by centrifugal force, thereby keeping the filter screen clean and effectively filtering the oil.

[0023] Please refer to the attached Figures 1 to 3The present application provides a petroleum filtering device, comprising a housing 1 and a first sprocket 2, a second sprocket 3, a transmission chain 4, a support plate 5 and a filter screen 6 arranged in the housing 1. A feed pipe 7 is connected to the side wall of the housing 1; a first discharge pipe 8 is arranged on the side of the housing 1 close to the first sprocket 2, a second discharge pipe 9 is arranged on the side close to the second sprocket 3, and a third discharge pipe 10 is arranged at the center of the bottom; the first sprocket 2 and the second sprocket 3 rotate under the drive of a driving mechanism, the diameter of the first sprocket 2 is smaller than the diameter of the second sprocket 3, the transmission chain 4 is wound around the first sprocket 2 and the second sprocket 3, the transmission chain 4 is provided with the support plate 5, adjacent support plates 5 are connected by a flexible sealing belt 26, the support plate 5 is provided with a through hole 11, and the filter screen 6 is arranged in the through hole 11. The first sprocket 2 and the second sprocket 3 are driven to rotate under the action of the driving structure, and the first sprocket 2 and the second sprocket 3 rotate when the first sprocket 2 and the second sprocket 3 rotate, and the transmission chain 4 is driven to rotate, and the transmission chain 4 is provided with a support plate 5, and the support plate 5 can be connected with the pin shaft or the outer chain plate of the transmission chain 4. When the transmission chain 4 rotates, the support plate 5 is driven to move. The support plates 5 are connected by a flexible sealing belt to prevent oil from passing through the gaps between the support plates 5. The through hole 11 on the support plate 5 is provided with a filter screen 6, which is used to filter the oil. The unfiltered oil enters the housing 1 and is located outside the area surrounded by the filter screen 6. The oil is filtered when passing through the filter screen 6, and finally discharged from the third discharge pipe 10 located inside the area surrounded by the filter screen 6. During filtering, the driving mechanism drives the filter screen 6 to rotate. When it rotates to the position of the first sprocket 2, due to its small diameter, it is subjected to a large centrifugal force, so most of the impurities on the filter screen 6 are thrown out, thereby improving the cleaning ability of the filter screen 6, and forming a high impurity area on the side close to the first sprocket 2. The oil in the high impurity area is discharged from the first discharge pipe 8. When the filter screen 6 rotates to the position of the second sprocket 3, the filter screen 6 is also affected by centrifugal force, but the centrifugal force it is subjected to is small, and a small number of large particles of impurities on the filter screen 6 are thrown out, forming a low impurity zone on the side close to the second sprocket 3, and the oil in the low impurity zone is discharged from the second discharge pipe 9. The present invention can filter and intercept impurities in the oil during filtration, and form three areas with different impurity contents, and the oil can be transported to subsequent processing devices for targeted processing, thereby improving the effect of oil filtration. During the filtration process, the impurities attached to the filter screen 6 can be separated by centrifugal force, so as to keep the filter screen 6 clean and effectively filter the oil.

[0024] Specifically, the housing 1 includes a bottom plate 12, a side plate and a top plate 13, the bottom plate 12 is connected to the side plate, the side plate is connected to the top plate 13, the side plate includes a first arc plate 14, a second arc plate 15 and a straight plate 16, the first sprocket 2 is located at an eccentric position of the first arc plate 14, the second sprocket 3 is located at an eccentric position of the second arc plate 15, and the ends of the first arc plate 14 and the second arc plate 15 are connected through the straight plate 16. When the filter 6 rotates, the oil will be driven to move in the housing 1. The side wall of the housing 1 and the filter 6 have different intervals. With the direction of oil flow, the interval between the first sprocket 2 and the side plate gradually decreases and then increases, and the interval between the second sprocket 3 and the side plate also gradually decreases and then increases. When the oil passes through an area with a small interval, the flow rate increases, which promotes the separation of impurities and particles in the area from the filter 6.

[0025] Specifically, the straight plate 16 is provided with a channel connected to the feed pipe 7, the first curved plate 14 is provided with a channel connected to the first discharge pipe 8, the second curved plate 15 is provided with a channel connected to the second discharge pipe 9, and the bottom plate 12 is provided with a channel connected to the third discharge pipe 10. After passing through the velocity increasing area, the oil enters the area with large spacing. The area with large spacing has a small cross-sectional area, and the velocity here is reduced, so that impurities and particles gather here, and the gathered impurities and particles are discharged through the first discharge pipe and the second discharge pipe.

[0026] Specifically, the top plate 13 is detachably connected to the side plate, and the bottom plate 12 is fixedly connected to the side plate. The top plate 13 is connected to the top of the side plate by a snap connection or the like, so that the top plate 13 can be removed from above to facilitate cleaning of the interior of the filter device.

[0027] Specifically, a disc 17 is provided above the first sprocket 2 and the second sprocket 3, a shielding strip 18 is provided between the first sprocket 2 and the second sprocket 3, the shielding strip 18 is tangent to the disc 17, the bottom of the shielding strip 18 is connected to the partition 27, the third discharge pipe 10 is connected from the bottom to the top of the partition 27, and the bottom of the support plate 5 is provided with an elastic sealing strip 19 corresponding to the disc 17 and the shielding strip 18, and the sides of the sealing strip 19 abut against each other. When the support plate 5 moves with the transmission chain 4, the sealing tape is attached to the disc 17 and rotates with the disc 17, so as to seal the bottom of the support plate 5, which can prevent oil from flowing through the gap and improve the filtering effect. When the support plate 5 moves to the position of the shielding strip 18, the sealing strip 19 is attached to the shielding strip 18, which also prevents oil from flowing through the gap.

[0028] Specifically, the driving mechanism includes a motor 20, a first pulley 21, a second pulley 22 and a transmission belt 23. The transmission ratio of the first pulley 21 and the second pulley 22 is equal to the transmission ratio of the first sprocket 2 and the second sprocket 3. The first pulley 21 and the second pulley 22 are connected by the transmission belt 23. The motor 20 is connected to the first pulley 21 or the second pulley 22. When the motor 20 rotates, it drives the first pulley 21 or the second pulley 22 to rotate, and then drives the other pulley to rotate through the transmission belt 23. Through the transmission of the first pulley 21 and the second pulley 22, the force between the sprocket and the transmission chain 4 can be reduced, and the service life of the transmission chain 4 can be increased.

[0029] Specifically, a support leg 24 is provided at the bottom of the housing 1 , and the housing 1 is supported by the support leg 24 . The support leg 24 is H-shaped, so as to improve the strength of the support leg 24 .

[0030] Specifically, a mounting plate 25 is provided at the bottom of the supporting leg 24 , and the motor 20 is fixedly connected to the mounting plate 25 , so as to facilitate the installation of the motor 20 .

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
