Description

Technical Field

[0001] The present invention relates to the field of bag filters, and specifically to a blowing device for a bag filter. Background Art

[0002] During industrial production processes, bag filters, as common air purification devices, are widely used in multiple fields. However, as the usage time increases, a large amount of dust gradually accumulates on the surface of the bags, resulting in a decrease in dust removal efficiency and an increase in equipment resistance, seriously affecting the normal operation and service life of the bag filters.

[0003] The traditional dust cleaning methods for bag filters mainly include mechanical vibration type and high-pressure air pulse blowing type. The mechanical vibration type has limited dust cleaning strength and is difficult to thoroughly remove the dust on the surface of the bags; while the high-pressure air pulse blowing type has better cleaning effects, but has higher energy consumption, and the high-pressure air flow will cause certain damage to the bags, shortening the service life of the bags. In addition, most of the existing dust cleaning devices can only perform blowing or patting in a single direction and cannot clean the bags comprehensively and evenly, making the dust cleaning effect not ideal and unable to meet the requirements of modern industries for high efficiency, energy conservation, and environmental protection. Summary of the Invention

[0004] The purpose of the present invention is to provide a blowing device for a bag filter. To achieve the above purpose, the present invention provides the following technical solutions: including a dust collector body, a driving transmission component for driving is arranged inside the dust collector body, and a blowing component is arranged on one side of the driving transmission component for performing a blowing operation on a provided bag body, and a patting component is arranged on one side of the blowing component for performing a patting operation on the bag body. The driving transmission component includes a driving component for driving the blowing component and the patting component to perform reciprocating up and down movement, and the driving transmission component further includes a transmission component driven by the driving component for driving the blowing component and the patting component to perform reciprocating rotation;

[0005] As a further preference of this technical solution: The driving component includes an air supply pipe, the air supply pipe is fixedly arranged inside the dust collector body, a rotating shaft is rotatably connected inside the air supply pipe, a driving transmission impeller is arranged on the outer side of the rotating shaft, a first transmission circular gear is fixedly arranged at the upper end of the rotating shaft, a first driven circular gear is meshed on one side of the first transmission circular gear, and a reciprocating lead screw is arranged at the middle position of the first driven circular gear for driving the blowing component and the patting component to move up and down;

[0006] As a further preference of this technical solution: The transmission component includes a second transmission circular gear, a connecting bottom plate is arranged below the second transmission circular gear, and a second driven circular gear is rotatably connected to the upper side of the connecting bottom plate;

[0007] As a further optimization of this technical solution: The blowing assembly includes a blower, which is fixedly arranged outside the dust collector body. One end of the blower is connected to a connecting hard pipe, and one end of the connecting hard pipe is connected to a connecting flexible pipe. One end of the connecting flexible pipe is connected to a blowing ring, and the inner side of the blowing ring is connected with a first air outlet pipe and a second air outlet pipe;

[0008] As a further optimization of this technical solution: The flapping assembly includes a connecting housing, which is fixedly arranged above the second driven spur gear. A fixed plate is fixedly arranged inside the connecting housing. A flapping drive impeller is rotatably connected to an extension plate on one side of the fixed plate. A connecting disc is fixedly connected to the flapping drive impeller. A toggle rod is fixedly arranged on the connecting disc. A connecting frame is arranged outside the toggle rod. A push-pull plate is fixedly arranged on one side of the connecting frame. A flapping ring is fixedly arranged at the end of the push-pull plate away from the connecting frame;

[0009] As a further optimization of this technical solution: The cloth bag body is fixedly arranged below the air supply pipe, and the cloth bag body is arranged inside the connecting housing and penetrates through the connecting bottom plate.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. In the present invention, by driving the transmission assembly to drive the connecting housing and the blowing ring to move up and down and rotate synchronously, the blower of the blowing assembly blows air into the blowing ring through the connecting hard pipe. The first air outlet pipe blows the outside of the cloth bag body, and the second air outlet pipe blows the flapping drive impeller, which drives the flapping ring to reciprocally flap the cloth bag body through transmission. This all-round blowing and flapping operation can effectively remove the dust on the surface of the cloth bag and improve the dust removal efficiency;

[0012] 2. In the present invention, by combining blowing and flapping, and the two can cooperate with each other. When blowing the cloth bag body, the flapping assembly synchronously flaps the cloth bag, so that the cloth bag is under the dual action of air flow impact and mechanical vibration, which is more conducive to the falling off of dust. Compared with the traditional single blowing or flapping dust cleaning method, the dust cleaning effect is more remarkable, the cloth bag can be cleaned more thoroughly, and the filtering effect and performance stability of the bag filter can be ensured. At the same time, the driving transmission assembly of this device adopts a wind-driven method, which does not require additional power equipment such as motors, reduces energy consumption and equipment costs, improves energy utilization efficiency, and meets the requirements of energy conservation and environmental protection.
