Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and more specifically to a cyclone dust removal device for preventing back-mixing. Background Technology

[0002] In modern industrial production, such as in the chemical, metallurgical, building materials, and power industries, numerous processes generate dust-laden gases. If these dust-laden gases are released directly into the atmosphere without treatment, they will cause serious environmental pollution and harm human health. For example, dust particles reduce air quality, trigger respiratory diseases, and adversely affect ecosystems such as soil and water bodies, leading to problems like acid rain and decreased soil fertility. Therefore, efficient dust removal equipment is crucial for controlling industrial dust emissions.

[0003] As shown in the prior art published in CN210058644U, although this prior art uses an internal separation assembly installed in the inner cavity of the outer separation shell to form a first annular dust outlet channel and a first airflow channel, thus achieving primary separation, the separated particles are output from the bottom dust outlet; the dust-laden gas enters the first airflow channel, and due to the reduced rotation radius and increased rotation speed of the rotating gas, smaller particles can be separated and discharged from the inner dust outlet. During the separation process, because the first annular dust outlet channel is slit-shaped, back-mixing of solid particles does not occur. However, dust in this prior art still easily adheres to the inside of the cyclone dust collector, and dust adhesion can easily affect the subsequent cyclone dust removal effect. Utility Model Content

[0004] To overcome the aforementioned deficiencies in the prior art, this utility model provides a cyclone dust collector that prevents back-mixing. A servo motor drives a main gear to rotate, which in turn drives a support ring to rotate via a meshing driven gear. The support ring, in turn, rotates multiple mounting posts on a movable ring, causing springs and balls on the mounting posts to repeatedly strike contact plates. The high-frequency striking of the contact plates by the balls generates directional vibration waves, effectively shaking off particles adhering to the cyclone dust collector. This achieves automatic dust removal and prevents dust adhesion, ensuring the performance of the cyclone dust collector and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cyclone dust collector for preventing back-mixing, comprising a striking element installed on the outside of the anti-back-mixing cyclone dust collector to prevent dust from adhering to the inner wall of the cyclone dust collector;

[0006] The striking component includes a movable ring sleeved on the outside of the cyclone dust collector. The inner side of the movable ring is provided with a plurality of contact pieces arranged in a ring array on the outside of the cyclone dust collector, and the outer side of the movable ring is provided with a plurality of elastic elements for striking the contact pieces.

[0007] Each set of elastic elements includes a mounting ring embedded inside the movable ring. The mounting ring is threaded with a mounting post inside, and a spring is installed on the side of the mounting post closer to the cyclone dust collector. A ball is installed on the side of the spring away from the mounting post.

[0008] In a preferred embodiment, a support ring is installed at the bottom of the movable ring and sleeved on the outside of the cyclone dust collector. The bottom end of the support ring is movably connected to the outside of the cyclone dust collector through a bearing. Through the movable connection between the support ring and the cyclone dust collector, the support ring can drive the movable ring to rotate, thereby facilitating the ball on the movable ring to strike the contact plate.

[0009] In a preferred embodiment, a driven gear is sleeved on the bottom of the support ring, and a main gear is meshed at one end of the driven gear. The main gear is driven to rotate by a drive component outside the cyclone dust collector. The main gear drives the meshed driven gear to rotate, and the driven gear drives the support ring to rotate, thereby achieving the effect of driving the movable ring to drive the ball to strike the contact plate.

[0010] In a preferred embodiment, the driving component includes a support plate, which is installed on the side of the cyclone dust collector corresponding to the main gear. A servo motor is installed on the top of the support plate, and the output shaft of the servo motor is fixed together with the main gear. The support plate supports and fixes the servo motor to ensure the stability of the servo motor's operation. Then, the servo motor drives the main gear to rotate, which in turn drives the meshing driven gear to rotate. Finally, the driven gear drives the support ring and the movable ring to rotate.

[0011] In a preferred embodiment, the same protective ring shell is fitted onto the top of the driven gear and the master gear. The protective ring shell is fitted outside the support ring to shield and protect the master gear and the driven gear, preventing impact and collision from damaging the master gear and the driven gear, and ensuring the performance of the master gear and the driven gear.

[0012] In a preferred embodiment, a plurality of pillars arranged in a ring array are installed on the outer side of the protective ring shell, and the bottom end of the pillars is fixed to the outside of the cyclone dust collector. Through the connection between the pillars and the cyclone dust collector, the pillars can support the protective ring shell, thereby ensuring the stability of the protective ring shell.

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

[0014] The servo motor drives the main gear to rotate, which in turn drives the support ring to rotate through the meshing driven gear. The support ring then rotates together with multiple mounting posts on the movable ring, causing the springs and balls on the mounting posts to repeatedly strike the contact plates. The high-frequency striking of the contact plates by the balls generates directional vibration waves, which effectively shakes off particles adhering to the cyclone dust collector, achieving automatic dust removal and preventing dust adhesion, thus ensuring the performance of the cyclone dust collector.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figure 1-5 This utility model provides a cyclone dust collector for preventing back-mixing, including a striking element installed on the outside of the anti-back-mixing cyclone dust collector 1 to prevent dust from adhering to the inner wall of the cyclone dust collector 1; the striking element includes a movable ring 2 sleeved on the outside of the cyclone dust collector 1, the inner side of the movable ring 2 is provided with a plurality of contact pieces 3 arranged in a ring array on the outside of the cyclone dust collector 1, and the outside of the movable ring 2 is provided with a plurality of elastic elements for striking the contact pieces 3; each set of elastic elements includes a mounting ring 4 embedded in the inside of the movable ring 2, the mounting ring 4 is threadedly connected to a mounting post 5, and a spring 6 is installed on the side of the mounting post 5 near the cyclone dust collector 1, and a ball 7 is installed on the side of the spring 6 away from the mounting post 5.

[0023] Cyclone dust collector 1 utilizes cyclone dust collection technology, a common dry dust removal method with advantages such as simple structure, low cost, and convenient maintenance, and has been widely used in industrial dust removal. Its working principle is based on centrifugal force, causing dust-laden gas to rotate within the cyclone dust collector 1. Dust particles are propelled by centrifugal force against the collector wall and fall along the wall into the ash hopper, while the purified gas is discharged from the central exhaust pipe. However, during use, some dust still adheres to the inner wall of the cyclone dust collector 1. This dust accumulation increases airflow resistance, thus affecting the performance of the cyclone dust collector 1.

[0024] like Figure 1-5 As shown, during the process of striking the cyclone dust collector 1 using the aforementioned elastic element, a support ring 8 is installed at the bottom of the movable ring 2 and sleeved on the outside of the cyclone dust collector 1. The bottom end of the support ring 8 is movably connected to the outside of the cyclone dust collector 1 through a bearing. A driven gear 9 is sleeved on the outside of the bottom end of the support ring 8. One end of the driven gear 9 is meshed with a main gear 10. The outside of the cyclone dust collector 1 drives the main gear 10 to rotate through a driving component. The driving component includes a support plate 11. The support plate 11 is installed on the side of the outside of the cyclone dust collector 1 corresponding to the main gear 10, and a servo motor 12 is installed on the top of the support plate 11. The output shaft of the servo motor 12 is fixed together with the main gear 10.

[0025] The operator drives the main gear 10 to rotate via the servo motor 12. The main gear 10 drives the support ring 8 to rotate via the meshing driven gear 9. Since the support ring 8 is fixedly connected to the movable ring 2, the support ring 8 can rotate together with the multiple mounting posts 5 on the movable ring 2. As the mounting posts 5 rotate with the movable ring 2, they drive the ball 7 on the spring 6 to repeatedly strike the contact plate 3. The high-frequency striking of the ball 7 on the contact plate 3 generates directional vibration waves, which effectively shake off the particles adhering to the cyclone dust collector 1, achieving automatic dust removal and preventing dust adhesion.

[0026] To prevent damage to the main gear 10 and driven gear 9 from external debris impacts, protective measures are needed for the main gear 10 and driven gear 9, such as... Figure 1-3As shown, the same protective ring shell 13 is fitted onto the top of the driven gear 9 and the main gear 10. The protective ring shell 13 is fitted onto the outside of the support ring 8. Multiple support columns 14 arranged in a circular array are installed on the outside of the protective ring shell 13, and the bottom ends of the support columns 14 are fixed to the outside of the cyclone dust collector 1. The support columns 14 fix the protective ring shell 13 to the outside of the cyclone dust collector 1, and the protective ring shell 13 is fitted onto the outside of the main gear 10 and the driven gear 9. In this way, the protective ring shell 13 can protect the main gear 10 and the driven gear 9, avoid damage to the main gear 10 and the driven gear 9 from external impacts, ensure the performance of the main gear 10 and the driven gear 9, and extend the service life of the main gear 10 and the driven gear 9.

[0027] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
