DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] Embodiment 1

[0025] An oilfield production filter device comprises a body 1, an oil discharge port 19 is arranged on the surface of the body 1, a filter cartridge 2 is arranged concentrically and rotatably inside the body 1, a bracket 3 is fixedly arranged on the surface of the body 1, a hot air conveying pipe 4 is fixed to one end of the bracket 3, a pipe 5 is key-connected to the other end of the bracket 3, the pipe 5 is slidably arranged on the surface of the hot air conveying pipe 4, a motor 6 is arranged at the bottom of the body 1, an output end of the motor 6 is connected to the bottom of the filter cartridge 2 through a through-machine, the pipe 5 is connected to the output end of the motor 6 through a reciprocating mechanism, a plurality of branches 7 are vertically arranged on the surface of the pipe 5, a main road 8 is vertically arranged on the surface of the pipe 5, and the main road 8 and the branch road 7 are perpendicular to each other.

[0026] See also Figure 1 and 2 Since the filter cartridge 2 is continuously rotating, while the pipeline 5, the main path 8 and the branch path 7 cannot rotate, the filter cartridge 2 can drive the crude oil to collide with the pipeline 5, the main path 8 and the branch path 7, thereby stirring and flipping the crude oil through the pipeline 5, the main path 8 and the branch path 7 to improve the heating effect and filtering effect of the crude oil.

[0027] The reciprocating mechanism includes a connecting arm 9, a connecting seat 10, a swing arm 11, a rotating shaft 12 and a crankshaft 13. The top of the connecting arm 9 is fixed to the surface of the pipeline 5. The connecting seat 10 is vertically arranged at the bottom of the connecting arm 9. One end of the swing arm 11 is hinged to the connecting seat 10. The crankshaft 13 is rotatably arranged at the bottom of the machine body 1 through the rotating shaft 12. The other end of the swing arm 11 is rotatably arranged at the eccentric end of the crankshaft 13. The crankshaft 13 is connected to the motor 6 through a transmission mechanism.

[0028] Please refer to Figure 3 , when the crankshaft 13 rotates, it can drive one end of the swing arm 11 to rotate synchronously. At this time, the crankshaft 13 drives one end of the swing arm 11 to revolve. Since the other end of the swing arm 11 is hinged to the connecting seat 10, the swing arm 11 can drive the connecting arm 9 to perform horizontal reciprocating motion through the connecting seat 10 at this time. When the connecting arm 9 moves, it can drive the pipeline 5 to move synchronously, so that the pipeline 5 can drive the main path 8 and the branch path 7 to move synchronously. Since the hot air delivery pipe 4 continuously delivers hot air into the pipeline 5, when the connecting arm 9 moves towards the direction close to the machine body 1, the connecting arm 9 can drive the main path 8 and the branch path 7 to move towards the direction close to the middle part of the filter cartridge 2 through the pipeline 5, and then deliver a part of the hot air to the central position of the crude oil. When the connecting arm 9 moves towards the direction away from the machine body 1, the connecting arm 9 can drive the main path 8 and the branch path 7 to move towards the direction close to the edge of the filter cartridge 2 through the pipeline 5, and then deliver a part of the hot air to the edge position of the crude oil, greatly improving the heating effect on the crude oil.

[0029] The transmission mechanism includes a driving gear 14 and a driven gear 15. The driving gear 14 is key-connected to the output end of the motor 6. The driven gear 15 is key-connected to the surface of the rotating shaft 12. The driven gear 15 meshes with the driving gear 14.

[0030] Please refer to Figure 3 and 4 , when the motor 6 rotates, it can drive the driving gear 14 to rotate. When the driving gear 14 rotates, it can drive the two rotating shafts 12 to rotate simultaneously through the two driven gears 15, so as to realize the drive of the two crankshafts 13.

[0031] Embodiment 2

[0032] In the above scheme, the pipeline 5 is driven to move synchronously by the horizontal reciprocating motion of the connecting arm 9. However, since the connecting arm 9 is relatively long as a whole, when the connecting arm 9 is driven from the bottom, it is necessary to ensure that the connecting arm 9 can only perform horizontal reciprocating motion. Therefore, in this embodiment, a sleeve 16 is vertically arranged on the surface of the body 1, and a limit rod 17 is vertically fixed on the surface of the connecting arm 9. One end of the limit rod 17 is slidably arranged inside the sleeve 16. A track is fixedly arranged on the inner wall of the bracket 3, and the connecting arm 9 is slidably arranged on the inner wall of the bracket 3 through the track. A support rod 18 is fixed to the bottom of the bracket 3, and one end of the support rod 18 is fixed to the surface of the body 1, and the support rod 18 is inclined.

[0033] See also Figure 1 When the connecting arm 9 moves, it can drive the limiting rod 17 to move synchronously inside the sleeve 16. The setting of the limiting rod 17 and the sleeve 16 can limit the movement process of the connecting arm 9, and the connecting arm 9 can also slide on the track of the inner wall of the bracket 3 when moving, further limiting the movement process of the connecting arm 9. In order to ensure the connection strength between the bracket 3 and the body 1, this embodiment provides an inclined support rod 18 between the bracket 3 and the body 1, so that a stable triangular structure can be formed between the body 1, the bracket 3 and the support rod 18, thereby improving the connection strength of the bracket 3.

[0034] Working principle: When in use, the crude oil is passed into the filter cartridge 2, and then the motor 6 is started, the motor 6 can drive the filter cartridge 2 to rotate, so that the crude oil is filtered through the filter cartridge 2, and the filtered crude oil can enter the machine body 1 through the filter cartridge 2, and finally discharged to the outside through the oil discharge port 19;

[0035] The motor 6 can also drive the driving gear 14 to rotate in the process of driving the filter cartridge 2 to rotate. The driving gear 14 can drive the two driven gears 15 to rotate at the same time. The driven gear 15 can drive the rotating shaft 12 to rotate. The rotating shaft 12 drives the crankshaft 13 to rotate when rotating. The eccentric end of the crankshaft 13 forms a crank-connecting rod mechanism through the swing arm 11 and the connecting seat 10, thereby driving the connecting arm 9 to perform horizontal reciprocating motion on the surface of the body 1. At this time, the connecting arm 9 can drive the pipeline 5 to move synchronously;

[0036] When the pipeline 5 moves, it can drive the main path 8 and the branch path 7 to move synchronously. When the connecting arm 9 moves toward the direction close to the body 1, the connecting arm 9 can drive the main path 8 and the branch path 7 to move toward the middle part of the filter cartridge 2 through the pipeline 5, thereby transporting a part of the hot air to the center position of the crude oil. When the connecting arm 9 moves in the direction away from the body 1, the connecting arm 9 can drive the main path 8 and the branch path 7 to move toward the edge of the filter cartridge 2 through the pipeline 5, thereby transporting a part of the hot air to the edge position of the crude oil, so that the hot air can evenly heat the crude oil in every part of the filter cartridge 2.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
