Description

Technical Field

[0001] The present invention relates to the field of air filters, and particularly relates to an oil impregnating device for filter paper of an air filter. Background Art

[0002] Most filter papers need to be impregnated with oil after being processed and formed. The oil can provide certain protection to the filter paper, making it not easily oxidized by air, thus shortening its lifespan. Therefore, impregnating the filter paper with oil has become an essential process, and the oil impregnating device has also become a relatively popular equipment.

[0003] The existing devices can only soak the filter paper by putting it into the oil tank during use, and cannot perform automatic oil impregnation on a large number of filter papers in a production line manner, which greatly reduces the oil impregnation speed of the filter paper, thus affecting the production efficiency. For this reason, there is an oil impregnating device for filter paper of an air filter with the patent number CN214143051U to solve the above problems. However, this device has the following defects when in use, such as: the filter paper slides and soaks in the static liquid, which easily causes the filter paper not to contact the oil well, thereby affecting its oil impregnation effect and efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an oil impregnating device for filter paper of an air filter.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] An oil impregnating device for filter paper of an air filter, including an oil tank. Both sides of the top of the oil tank are provided with driving rollers for supporting the filter paper, and the driving rollers are driven by a driving mechanism:

[0007] A U-shaped frame with an opening facing downwards is arranged in the oil tank. A transmission roller is arranged in the opening of the U-shaped frame, and L-shaped plates buckled on the top ends of the side walls of the oil tank are arranged at both ends of the U-shaped frame;

[0008] A hydraulic rod is arranged on the top of the oil tank. The hydraulic rod is connected to an installation frame suspended directly above the U-shaped frame through an L-shaped rod. A vertical pipe extending above the U-shaped frame is fixed on the installation frame through a bearing I. A liquid inlet pipe inserted into the vertical pipe is fixed on the installation frame through a bracket. A toothed ring is arranged at the top end of the vertical pipe. A gear meshing with the toothed ring and driven by a motor is arranged on the toothed ring. A baffle is also arranged at the bottom of the vertical pipe. A connecting rod connected to the U-shaped frame is fixed in the vertical pipe below the baffle through a bearing II. Multiple groups of branch pipes are radially arranged on the vertical pipe above the baffle, and water outlet holes are uniformly arranged on the side walls of the branch pipes.

[0009] Preferably, multiple groups of branch pipes are located between two L-shaped plates and within the opening of the triangle formed between two driving rollers and the transmission roller.

[0010] Preferably, the L-shaped plate is fixed to the top end of the side wall of the oil tank by bolts.

[0011] Preferably, the liquid inlet pipe is connected to the fuel tank through a pipeline, and a pump is provided on the pipeline.

[0012] Preferably, the mounting bracket is arranged above the oil tank, and the motor is suspended at the bottom of the mounting bracket and fixedly connected thereto.

[0013] Preferably, a mounting plate for mounting a hydraulic rod is erected on the top of the oil tank.

[0014] The beneficial effects of the present invention are as follows: In the present invention, the filter paper flows through the oil liquid in the oil tank by means of being driven by a driving roller and transmitted by a transmission roller, so as to perform the oil immersion operation on it. In the above process, the motor drives the gear and the toothed ring to drive the vertical pipe to rotate in the bearing I. At this time, the vertical pipe drives the branch pipe to rotate in the oil liquid in the oil tank, so as to cause the liquid in the oil tank to fluctuate so that it can fully contact with the filter paper, thereby improving the oil immersion effect of the filter paper. At the same time, the oil liquid is injected into the vertical pipe through the liquid inlet pipe and discharged by the branch pipe. The fresh oil liquid is guided to different areas in the oil tank by the branch pipe during the rotation process, so that it can fully contact and mix with the oil liquid in the oil tank, and thus the oil immersion work on the filter paper can be better carried out.

[0020] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0021] An oil impregnating device for an air filter paper, comprising an oil tank 1, wherein driving rollers 2 for supporting the filter paper are arranged on both sides of the top of the oil tank 1, and the driving rollers 2 are driven by a driving mechanism:

[0022] A U-shaped frame 3 with an opening facing downwards is arranged in the oil tank 1. A driving roller 4 is arranged in the opening of the U-shaped frame 3. L-shaped plates 5 buckled on the top ends of the side walls of the oil tank 1 are arranged at both ends of the U-shaped frame 3, and the L-shaped plates 5 are fixed on the top ends of the side walls of the oil tank 1 by bolts;

[0023] A hydraulic rod 6 is arranged on the top of the oil tank 1, and a mounting plate 20 for mounting the hydraulic rod 6 is erected on the top of the oil tank 1. The hydraulic rod 6 is connected to a mounting frame 8 suspended directly above the U-shaped frame 3 through an L-shaped rod 7. A vertical pipe 10 extending above the U-shaped frame 3 is fixed on the mounting frame 8 through a bearing I9. A liquid inlet pipe 12 inserted into the vertical pipe 10 is fixed on the mounting frame 8 through a bracket 11. A toothed ring 13 is arranged at the top end of the vertical pipe 10. A gear 14 meshing with the toothed ring 13 and driven by a motor 15 is arranged on the toothed ring 13. A baffle 16 is further arranged at the bottom inside the vertical pipe 10. A connecting rod 18 connected to the U-shaped frame 3 is fixed inside the vertical pipe 10 below the baffle 16 through a bearing II17. A plurality of groups of branch pipes 19 are radially arranged on the vertical pipe 10 above the baffle 16, and water outlet holes are uniformly arranged on the side walls of the branch pipes 19.

[0024] As Figure 1 、 2 shown, a plurality of groups of branch pipes 19 are located between two groups of L-shaped plates 5 and in the opening of the triangle formed between two groups of driving rollers 2 and the driving roller 4. This enables that when the vertical pipe 10 drives the branch pipes 19 to rotate, they will not come into contact with the filter paper and the L-shaped plates 5.

[0025] In this embodiment, the liquid inlet pipe 12 is connected to an oil tank through a pipeline, and a pump is arranged on the pipeline.

[0026] In this embodiment, the mounting frame 8 is arranged above the oil tank 1, and the motor 15 is suspended and fixedly connected to the bottom of the mounting frame 8.

[0027] The working principle of the present invention: As Figure 1 shown, the filter paper flows through the oil liquid in the oil tank 1 in a manner of being driven by the driving rollers 2 and transmitted by the driving roller 4, and then the oil impregnation work is carried out on it. During the above process, the motor 15 drives the gear 14 and the toothed ring 13 to drive the vertical pipe 10 to rotate in the bearing I9. At this time, the vertical pipe 10 drives the branch pipes 19 to rotate in the oil liquid in the oil tank 1, so as to make the liquid in the oil tank 1 fluctuate to make it fully contact with the filter paper, thereby improving the oil impregnation effect of the filter paper;

[0028] During the above process, when the vertical pipe 10 rotates, it will drive the bearing II 17 to rotate on the connecting rod 18, so that components such as the C-shaped frame 3 can support the vertical pipe 10 through the connecting rod 18 without affecting its rotation. At the same time, the oil liquid is injected into the vertical pipe 10 through the liquid inlet pipe 12 and discharged by the branch pipe 19. The fresh oil liquid is guided to different areas in the oil tank 1 through the branch pipe 19, so that it can fully contact and mix with the oil liquid in the oil tank 1, and then the filter paper can be better soaked with oil;

[0029] As Figure 1 shown, when placing the filter paper in the oil tank 1, at this time, the hydraulic rod 6 drives the L-shaped rod 7 to drive the mounting frame 8, the vertical pipe 10, the branch pipe 19, the connecting rod 18, the C-shaped frame 3 and the driving roller 4 to move up to the top of the oil tank 1. At this time, the filter paper can be placed on the two driving rollers 2 and passed through below the driving roller 4. Then, the hydraulic rod 6 drives the driving roller 4 to move down through the above components to squeeze the filter paper in the oil tank 1 and soak it in the liquid. At the same time, bolts are installed on the L-shaped plate 5 to lock and fix it on the side wall of the oil tank 1, so as to support and fix the C-shaped frame 3 and the driving roller 4.

[0030] The above has described the present invention in detail, but the above content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
