[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical-chemical methods to evacuate a container to obtain a vacuum. Generally speaking, a vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space by various methods. It is widely used in industries such as metallurgy, chemical industry, food, and electronic coating, and plays an important role in fields such as scientific research, industrial production, and medical equipment.

[0003] There is a vacuum pump with a publication number of CN105673523A, which specifically discloses that the vacuum pump is composed of a vacuum pump body, a support seat, a silencer, a shock absorption device, an impeller, an intake pipe, an exhaust pipe, a pipe sleeve, an air inlet, an exhaust port, a filtration device, and a descaling agent addition port. The vacuum pump provided by the present invention can effectively improve the shock absorption and noise reduction ability, reduce the content of solid particles in the exhaust gas, and contains a wear-resistant impeller, which can effectively improve the wear resistance of the pump, extend the service life of the pump, and save costs.

[0004] Since the exhaust pipe of the vacuum pump in the related technology lacks a filtration device, the solid particles and particulate matter in the exhaust gas cannot be effectively captured and filtered out. These particles may enter the surrounding equipment or instruments, resulting in problems such as blockage, damage, or performance reduction. For this reason, we propose a novel vacuum pump exhaust filtration device. Content of the Utility Model

The filtration structure and the first pipe are connected together by screws.

[0007] The filtering structure is arranged in a funnel shape with an opening at the lower end thereof. A number of uniformly distributed filtering grooves are formed in the filtering structure, and the filtering grooves penetrate through the filtering structure. A collecting mechanism is arranged in the first pipe, and the collecting mechanism is installed on the filtering structure and used for collecting filtered substances. The collecting mechanism includes a collecting groove located in the first pipe. An inner annular sheet is fixedly installed at the lower end of the filtering structure, and the collecting groove is sleeved on the lower end of the filtering structure and communicated with the filtering structure. The collecting groove and the inner annular sheet are connected together by screws. A cleaning mechanism is arranged in the first pipe, and the cleaning mechanism is installed on the collecting groove and can clean the filtering structure.

[0008] As a further technical solution of the present invention, sealing gaskets are arranged at the ports of the first pipe and the second pipe.

[0009] As a further technical solution of the present invention, the cleaning mechanism includes a bracket arranged inside the filtering structure. A plurality of strip-shaped rods distributed in a circumferential array are fixedly installed on the bracket. Brush hairs are arranged on one side of the strip-shaped rods facing the filtering structure, and the brush hairs are in contact with the surface of the filtering structure.

[0010] As a further technical solution of the present invention, a driving component is arranged in the collecting groove, and the driving component is connected to the bracket.

[0011] As a further technical solution of the present invention, the driving component includes a connecting shaft located in the collecting groove. The lower end of the connecting shaft is rotatably installed on the collecting groove, and the upper end of the connecting shaft is fixedly connected to the center of the bracket. A servo motor is fixedly installed at the bottom of the collecting groove, and the output shaft of the servo motor is fixedly connected to the connecting shaft.

[0013] The present invention provides a new type of vacuum pump exhaust filtering device, which has the following beneficial effects compared with the prior art:

[0014] 1. For the new type of vacuum pump exhaust filtering device designed in this way, solid particles and particulate matters in the exhaust are filtered and intercepted through the filtering grooves on the filtering structure, avoiding the problems of blockage, damage or performance reduction of the exhaust pipe of the vacuum pump. By arranging the filtering structure in a funnel shape, the pollutants remaining on the filtering structure will slide along the slope of the filtering structure and fall into the collecting groove to be collected, avoiding the blockage phenomenon of the filtering grooves during long-term use and enabling the filtering structure to maintain an efficient filtering effect.

[0015] 2. A novel exhaust filtration device for a vacuum pump in this design drives a connecting shaft to rotate through a servo motor. The bracket at the upper end of the connecting shaft rotates, and the bracket is connected to a strip-shaped rod and rotates synchronously.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4, the present utility model provides a technical solution for a new vacuum pump exhaust filtration device: A new vacuum pump exhaust filtration device includes a first pipe 1. A outer annular piece 2 is fixedly installed at the lower end of the first pipe 1. A second pipe 3 is sleeved on the lower end of the first pipe 1. The first pipe 1 is communicated with the second pipe 3. The second pipe 3 and the outer annular piece 2 are connected together by screws. A filtering structure 4 is arranged inside the first pipe 1. The filtering structure 4 and the first pipe 1 are connected together by screws. The filtering structure 4 is arranged in a funnel shape and the lower end of the filtering structure 4 is open. A number of uniformly distributed filtering grooves 5 are opened on the filtering structure 4. The filtering grooves 5 penetrate through the filtering structure 4. A collecting mechanism is arranged in the first pipe 1. The collecting mechanism is installed on the filtering structure 4 and is used for collecting filter substances. The collecting mechanism includes a collecting groove 6. The collecting groove 6 is located in the first pipe 1. An inner annular piece 7 is fixedly installed at the lower end of the filtering structure 4. The collecting groove 6 is sleeved on the lower end of the filtering structure 4 and is communicated with the filtering structure 4. The collecting groove 6 and the inner annular piece 7 are connected together by screws. A cleaning mechanism is arranged in the first pipe 1. The cleaning mechanism is installed on the collecting groove 6 and can clean the filtering structure 4. By connecting the upper port of the first pipe 1 to the exhaust pipe of the vacuum pump, the airflow discharged by the vacuum pump enters the first pipe 1 and is then discharged from the lower port of the second pipe 3. When the airflow enters the first pipe 1, it will pass through the filtering structure 4. The solid particles and particulate matters in the exhaust are filtered and intercepted through the filtering grooves 5 on the filtering structure 4, avoiding the problems of blockage, damage or performance reduction of the exhaust pipe of the vacuum pump.

[0023] Among them, as Figure 3 and Figure 4 shown, sealing washers 14 are arranged at the ports of the first pipe 1 and the second pipe 3. The cleaning mechanism includes a bracket 8. The bracket 8 is arranged inside the filtering structure 4. A plurality of strip-shaped rods 9 distributed in a circumferential array are fixedly installed on the bracket 8. Brush hairs 10 are arranged on the side of the strip-shaped rods 9 facing the filtering structure 4. The brush hairs 10 are in contact with the surface of the filtering structure 4. A driving component is arranged in the collecting groove 6. The driving component is connected to the bracket 8. The driving component includes a connecting shaft 11. The connecting shaft 11 is located in the collecting groove 6. The lower end of the connecting shaft 11 is rotatably installed on the collecting groove 6. The upper end of the connecting shaft 11 is fixedly connected to the center of the bracket 8. A servo motor 12 is fixedly installed at the bottom of the collecting groove 6. The output shaft of the servo motor 12 is fixedly connected to the connecting shaft 11. A protective cover 13 is sleeved outside the servo motor 12. The protective cover 13 is fixedly connected to the collecting groove 6. A plurality of strengthening rods 15 are arranged inside the bracket 8. Both ends of the strengthening rods 15 are fixedly connected to the bracket 8. By driving the connecting shaft 11 to rotate through the servo motor 12, the bracket 8 at the upper end of the connecting shaft 11 rotates. The bracket 8 and the strip-shaped rods 9 are connected and rotate synchronously. Thus, the brush hairs 10 on the strip-shaped rods 9 rotate around the connecting shaft 11 and clean the surface of the filtering structure 4, removing the pollutants blocking the filtering grooves 5.

[0024] The working principle of the present utility model is as follows: By connecting the upper port of the first pipeline 1 to the exhaust pipe of the vacuum pump, the airflow discharged by the vacuum pump enters the first pipeline 1 and then is discharged from the lower port of the second pipeline 3. When the airflow enters the first pipeline 1, it will pass through the filtering structure 4, and the solid particles and particulate matters in the exhaust gas are filtered and intercepted through the filtering grooves 5 on the filtering structure 4, avoiding the problems of blockage, damage or performance reduction of the exhaust pipe of the vacuum pump;

[0025] Meanwhile, since the filtering structure 4 is arranged in a funnel shape, the pollutants remaining on the filtering structure 4 will slide down along the slope of the filtering structure 4 and fall into the collection tank 6 for collection, avoiding the blockage phenomenon of the filtering grooves 5 during long-term use and enabling the filtering structure 4 to maintain an efficient filtering effect;

[0026] When the filtering grooves 5 are blocked by pollutants and the exhaust of the vacuum pump is not smooth, the servo motor 12 can be started to drive the connecting shaft 11 to rotate. The bracket 8 at the upper end of the connecting shaft 11 rotates, and the bracket 8 and the strip-shaped rod 9 are connected and rotate synchronously. Thus, the bristles 10 on the strip-shaped rod 9 rotate around the connecting shaft 11 and clean the surface of the filtering structure 4, removing the pollutants blocking the filtering grooves 5 and enabling the filtering grooves 5 to maintain an efficient ventilation state.

[0027] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
