Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and more specifically, to a multi-stage waste gas filtration device. Background Technology

[0002] Traditional exhaust gas filtration devices typically involve installing a filter screen inside a filter cartridge to remove particulate matter carried in the exhaust gas. However, as the usage time increases, particles continuously accumulate on the surface of the filter screen, causing the filtration effect of the filter screen to deteriorate.

[0003] Over time, solid particles will accumulate inside the filter cartridge, not only clogging the filter pores on the filter screen surface, but also reducing the volume of gas that the filter cartridge can hold. This requires the user to reduce the fan speed every once in a while to reduce the rate at which gas enters the filter cartridge, thereby reducing the noise and vibration of the filter cartridge. Once the solid particles accumulated inside the filter cartridge have been cleaned, the fan speed should be increased again.

[0004] The method of cleaning the filter cartridge involves manually scraping off the particles adhering to the inner wall of the cartridge, which is time-consuming and labor-intensive. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a multi-stage filtration device for exhaust gas. The technical problem to be solved by this utility model is: how to improve the convenience of cleaning solid particles fixed on the inner wall of the filter cylinder and the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage exhaust gas filtration device, comprising a filtration assembly including several single cylinders, each cylinder connected to a fan; a particle removal assembly including a scraper, a rotating ring, a limiting hole, and an M-rod; the bottom end of the vertical scraper is slidably connected to the bottom surface of the single cylinder, the outer side of the scraper is in contact with the inner wall of the single cylinder, a brush is fixed on the outer side of the scraper, the rotating ring is rotatably connected to the bottom surface of the single cylinder, a protrusion is fixed on the circumferential side of the rotating ring, the protrusion interferes with the scraper, a limiting hole is provided on the rotating ring, and the end of the M-rod can be inserted into the limiting hole to drive the rotating ring to rotate; adjacent single cylinders are connected by a pipe, and the filter screen located at the end face of the pipe is coplanar with the inner wall of the corresponding single cylinder.

[0007] In a preferred embodiment, the scraper and the bottom surface of the single cylinder are elastically slidably connected, the movable distance of the scraper is equal to the distance between two adjacent scrapers, and the scrapers are fixed together by reinforcing bars.

[0008] In a preferred embodiment, a push plate is rotatably connected to the rotating ring. The rotation center of the push plate is located in the middle of the bottom surface of the push plate, and the end of the push plate near the limiting hole can swing above several limiting holes.

[0009] In a preferred embodiment, a plurality of limiting holes are arranged at equal intervals along a straight line, and the M rod is used to simultaneously insert into two adjacent limiting holes.

[0010] In a preferred embodiment, the push plate is placed at an angle on the rotating ring, with the top edge of the push plate abutting the side of the corresponding rib and the bottom edge away from the rib.

[0011] In a preferred embodiment, the end of the push plate away from the limiting hole is tilted upwards toward the center of the bottom surface of the single cylinder.

[0012] In a preferred embodiment, the single cylinders are cylinder one, cylinder two, and cylinder three. The pipes connecting cylinder one and cylinder two are located at the upper part, and the pipes connecting cylinder two and cylinder three are located at the lower part. Cylinder one is connected to the factory building, and cylinder three is connected to the motor.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This application mainly utilizes an M-bar to drive a rotating ring and a push plate to rotate. The rotating ring and the scraper interfere with each other, allowing the scraper to scrape off solid particles fixed on the inner wall of the single cylinder and the filter screen.

[0025] Example

[0026] like Figures 1-6 This utility model provides a multi-stage filtration device for exhaust gas, including a filtration component 1 and a particle removal component 2. The particle removal component 2 is used to remove solid particles attached to the filtration component 1.

[0027] The filter assembly 1 includes several single cylinders, which can be cylinder 11, cylinder 2 12 and cylinder 3 13. Each single cylinder is connected to the others by a pipe, and the filter screen is placed on the port of the pipe.

[0028] The connecting pipes of cylinder 11 and cylinder 22 are laid at the top, and the connecting pipes of cylinder 22 and cylinder 313 are laid at the bottom. Cylinder 313 is connected to the fan, and the fan is controlled by the controller. It should be noted that the top of cylinder 11, cylinder 22 and cylinder 313 are each independently equipped with a fan electrically connected to the controller to improve the efficiency of the waste gas generated during the molecular sieve preparation process flowing in the filter assembly 1.

[0029] The particle removal assembly 2 is located inside each single cylinder. The particle removal assembly 2 includes a scraper 21, a reinforcing bar 22, a pad 23, a rotating ring 24, a push plate 25, and a limiting hole 26. A number of reinforcing bars 22 are arranged at equal intervals along the vertical direction. A number of scraper bars 21 are arranged on the circumference of the axis of the reinforcing bars 22. The scraper bars 21 connect the reinforcing bars 22 to form a cylindrical mesh. The outer side of the scraper bar 21 is in contact with the inner wall of the single cylinder. The reinforcing bars 22 are spaced apart from the inner wall of the single cylinder. An opening corresponding to the single cylinder outlet is opened on the cylindrical mesh to facilitate the cleaning of particles inside the single cylinder with a shovel with a handle.

[0030] A brush is fixed to the outside of the scraper 21. When the brush passes through the filter holes in the filter screen, it can clean and remove the particles stuck in the filter holes.

[0031] A pad 23 is fixed at the bottom of the single tube, and the outer ring of the pad 23 is rotatably connected by a bearing and a rotating ring 24.

[0032] At least two limiting holes 26 are provided on the rotating ring 24. The centers of the limiting holes 26 are located on the same straight line, and adjacent limiting holes 26 are evenly spaced. A push plate 25 is rotatably connected to the rotating ring 24. The lower surface of the push plate 25 is designed to fit the rotating ring 24 and the pad 23. The rotation center of the push plate 25 is located in the middle of the lower surface. One end of the push plate 25 passes over the limiting holes 26 during rotation. By using the M rod, the push plate 25 can be locked. Based on the rotatable motion of the rotating ring 24, with the center of the pad 23 as the center, by applying force to the M rod, the rotating ring 24 is driven to rotate at the bottom of the single cylinder. At the same time, the limiting holes 26 can push the particles located on the outer side of the pad 23 and the rotating ring 24 towards the center, pushing the particles that are originally difficult to collect towards the bottom center of the single cylinder. Then, the user only needs to use a shovel to scoop up the pile of particles located at the bottom center.

[0033] It should be noted that the distances from the two ends of the push plate 25 to the center of the pad 23 are different, with the distance at the end closer to the limiting hole 26 being smaller than that at the other end of the push plate 25. The tilt angle of the push plate 25 can be adjusted by engaging it in different limiting holes.

[0034] The edge of the rotating ring 24 has several protrusions. During the rotation of the rotating ring 24, the protrusions collide with several scraper rods 21. The vibration generated by the scraper rods 21 can shake off the particles attached to the scraper rods 21 and the reinforcing rods 22.

[0035] The scraper 21 and the bottom of the single cylinder are not fixed, but elastically sliding. The sliding path is an arc that coincides with the center of curvature and the center of the bottom surface of the single cylinder. The distance between the two endpoints of the arc is equal to the distance between two adjacent scraper 21s. The scraper 21 and the reinforcing bar 22 are driven to rotate by the protrusion of the rotating ring 24. When the scraper 21 moves to the end of the movable path, the protrusion and the scraper 21 deform. The scraper 21 vibrates and makes way for the protrusion so that the rotating ring 24 can pass over the scraper 21 and continue to rotate. This process is repeated so that the scraper 21 can scrape off the solid particles attached to the inner wall of the single cylinder.

[0036] The above design can also be used to clean the filter screen. When laying the filter screen, the surface of the filter screen and the inner wall of the single cylinder are coplanar, and the center of curvature of the filter screen is located on the axis of the single cylinder.

[0037] Preferably, the push plate 25 can be arranged at an angle, and the top edge of the push plate 25 is always in contact with the side of a corresponding rib 22, so that the rotating push plate 25 will not cause accidental interference with other components.

[0038] Preferably, the end of the push plate 25 away from the limiting hole 26 is tilted towards the center of the rotating ring 24. This method can also reduce the probability of accidental interference between the rotating push plate 25 and other components.

[0039] It should be noted that the M rod is used for the rotatable connection between the end of the insertion limit hole 26 and the handle.

[0040] In summary, this application mainly utilizes the M-bar to drive the rotating ring 24 and the push plate 25 to rotate. The rotating ring 24 interferes with the scraper 21, allowing the scraper 21 to scrape off the solid particles fixed on the inner wall of the single cylinder and the filter screen. The vibration generated between the scraper 21 and the rotating ring 24 can also remove the solid particles fixed on the scraper 21 and the reinforcing bar 22. At the same time, the push plate 25 can push the particles accumulated at the bottom edge of the single cylinder towards the bottom center, making it easier for the user to remove the cleaned solid particles. The above methods can improve the convenience of cleaning the particles fixed in the single cylinder, reduce the cleaning cost, shorten the time interval between two cleanings, and improve the cleaning effect, thereby ensuring the stability of the airflow in the single cylinder and the passability of the filter screen.
