Description

Technical Field

[0002] In the process of industrial production, in order to effectively control dust pollution, various dust removal technologies are constantly developing and improving. Among them, bag dust collectors with cyclone devices, as an important dust removal equipment, have been widely used in many fields.

[0003] In previous cyclone devices, the diameter of the cyclone channel is usually fixed, which makes it impossible to flexibly adjust when dealing with different working conditions. When the gas volume to be processed is large or the dust concentration is high, the cyclone channel with a fixed diameter may cause the channel to be blocked due to the high wind speed, reducing the separation efficiency, and also increasing the maintenance cost and downtime of the equipment. When the gas volume to be processed is small or the dust concentration is low, the cyclone channel with a fixed diameter may not be able to effectively use centrifugal force to separate the dust due to the low wind speed, affecting the overall dust removal effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a bag dust collector with a cyclone device is provided to achieve a more practical purpose. Utility Model Content

[0023] Embodiment:

[0024] As shown in the attached Figure 1 to the attached Figure 5 shown:

[0025] The present utility model provides a bag filter with a cyclone device, which includes a cyclone cylinder 1, a bracket 2, a dust removal device 3 and an aggregate hopper 4, and also includes a cyclone passage diameter adjustment component 5 and a cyclone component 6. The cyclone passage diameter adjustment component 5 includes an upper disc 501. A plurality of groups of sealing plates 503 are slidably installed on the bottom side of the upper disc 501. One side of the bottom ends of the plurality of groups of sealing plates 503 is provided with a round shaft 505, and a lower disc 507 is slidably installed through the round shaft 505 together. A gear ring 508 is fixedly installed on the bottom side of the lower disc 507. A gear 509 is meshed and installed on one side of the gear ring 508. The gear 509 is drivingly connected to a first driving motor, and the side wall of the first driving motor is fixedly connected to the inner wall of the cyclone cylinder 1.

[0026] Among them, a plurality of groups of chutes 502 are equally angled and opened on the bottom side of the upper disc 501. The top ends of the plurality of groups of sealing plates 503 are all provided with ribs 504 that match the chutes 502. The plurality of groups of sealing plates 503 are slidably connected to the corresponding chutes 502 through the ribs 504. This sliding connection method enables the sealing plates 503 to slide stably on the bottom side of the upper disc 501, ensuring the smoothness and accuracy of the cyclone passage diameter adjustment.

[0027] Among them, multiple groups of waist-shaped grooves 506 matching the circular shaft 505 are equiangularly opened on the top side of the lower disc 507. Multiple groups of sealing plates 503 are all slidably connected to the lower disc 507 through the circular shaft 505. The cooperation between the waist-shaped grooves 506 and the circular shaft 505 enables the lower disc 507 to drive the sealing plates 503 to move when rotating, thereby realizing the adjustment of the diameter of the cyclone channel and enhancing the adaptability of the equipment to different working conditions.

[0028] Among them, the cyclone assembly 6 is arranged at the junction of the cyclone cylinder 1 and the aggregate hopper 4, and the cyclone channel diameter adjustment assembly 5 is arranged near the top feed port of the cyclone cylinder 1. Such a layout is reasonable. The cyclone assembly 6 can more effectively perform cyclone separation on the dust-containing gas at the junction, while the cyclone channel diameter adjustment assembly 5 can timely adjust the channel diameter according to the working conditions at the feed port, improving the dust removal efficiency and the stability of the equipment.

[0029] Among them, the cyclone assembly 6 includes an installation cylinder 601. A first bevel gear 602 is rotatably installed at the inner bottom end of the installation cylinder 601. The top end of the first bevel gear 602 is drivingly connected to a servo motor 603, and the inner top end of the servo motor 603 is fixedly connected. Three groups of second bevel gears 604 are equiangularly meshed and installed at the top end of the first bevel gear 602. The three groups of second bevel gears 604 are all rotatably connected to the inner wall of the installation cylinder 601, and blades 605 are all installed through shafts. The middle part of the bottom end of the installation cylinder 601 is drivingly connected to a second driving motor, and the outer wall of the second driving motor is fixedly connected to the inner wall of the cyclone cylinder 1. The servo motor 603 drives the first bevel gear 602 to rotate, driving the three groups of second bevel gears 604 and the blades 605 to rotate, generating a strong cyclone, which can efficiently separate the dust particles in the dust-containing gas and improve the dust removal effect.

[0030] Among them, cloth bags are arranged at the bottom ends of the dust removal devices 3, and the upper ends of the cloth bags are fixedly connected to the tops of the dust removal devices 3 through fastening devices.

[0031] Working principle of this embodiment: The dusty gas enters the dust collector from the feed port at the top of the cyclone tube 1. When the dusty gas enters the cyclone tube 1, it first passes through the cyclone passage diameter adjusting assembly 5. At this time, the first driving motor starts, driving the gear 509 to rotate. The gear 509 meshes with the toothed ring 508, causing the lower disc 507 to rotate. The waist-shaped groove 506 on the top side of the lower disc 507 drives the round shaft 505 to move. The round shaft 505 then drives the sealing plate 503 to slide in the chute 502 on the bottom side of the upper disc 501 through the convex strip 504, realizing the movement of the sealing plate 503, thereby adjusting the diameter of the cyclone passage according to the actual working conditions. The adjusted dusty gas enters the area where the cyclone assembly 6 is located. The second driving motor in the cyclone assembly 6 drives the mounting cylinder 601 to rotate. At the same time, the servo motor 603 drives the first bevel gear 602 to rotate. The first bevel gear 602 drives three groups of second bevel gears 604 to rotate, causing the blades 605 to rotate, realizing the angle adjustment of the blades 605, and generating a strong cyclone. Under the action of the cyclone, the dust particles in the dusty gas are thrown towards the inner wall of the cyclone tube 1 due to the centrifugal force and fall downward into the aggregate hopper 4 under the action of gravity, initially realizing the separation of dust. The gas after preliminary cyclone separation continues to enter the dust removal device 3. In the dust removal device 3, when the gas passes through the cloth bag, the dust is intercepted by the cloth bag, and the purified gas passes through the cloth bag and is discharged from the dust collector. The upper end of the cloth bag is fixedly connected to the top of the dust removal device 3 through a fastening device, ensuring the stability of the cloth bag during the filtering process and enabling it to effectively intercept dust. After the dust collector operates for a period of time, a certain amount of dust will accumulate on the surface of the cloth bag. At this time, it is necessary to clean the cloth bag. Pulse jetting, back blowing and other methods can be used to remove the dust attached to the cloth bag and restore its filtering performance.

[0032] The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
