Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a bag filter dust collector. Background Technology

[0002] Baghouse dust collectors are dry dust filtration devices. After a period of use, excessively high resistance in the dust collector can significantly reduce the airflow of the dust collection system, necessitating cleaning. The accumulated dust on the filter bags is typically removed using backwashing. The removed dust falls into the dust hopper and is discharged through the dust removal device. Cleaning a baghouse dust collector when its resistance is too high is problematic because the filter bags contain a large amount of dust. After backwashing, the dust tends to form a compacted structure within the dust hopper, hindering its smooth flow to the dust removal device. Furthermore, since baghouse dust collectors are often installed on rooftops, humid weather can further compact the dust structure inside, potentially leading to agglomeration and further compromising the cleaning process. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a bag filter dust collector, which uses an agitation structure to keep the dust loose in the ash hopper, preventing the dust in the upper part of the ash hopper from being too compacted and unable to fall and be discharged smoothly.

[0004] The technical solution of this utility model is as follows: a bag filter includes a dust collection box, a dust hopper, and a dust discharge mechanism connected and communicating from top to bottom. The dust hopper has an input pipe on its side, the dust collection box has an output pipe on its side, and the dust discharge mechanism has a dust discharge port at its lower end. The dust hopper narrows from top to bottom, and an agitation structure is provided inside the dust hopper. One end of the agitation structure is rotatably connected to the input pipe, and the other end of the agitation structure is rotatably connected to the side wall of the dust hopper. The input end of the agitation structure is located outside the dust hopper.

[0005] Furthermore, an annular groove is provided on the inner side of the input pipe, and one end of the agitation structure is rotatably connected to the annular groove.

[0006] Furthermore, the output end of the agitation structure is a hexagonal prism structure.

[0007] Furthermore, the agitation structure consists of a circular ring, agitating blades, a connecting ring, and a rotating shaft. The agitating blades have a blade-shaped cross-section, and there are multiple agitating blades arranged in a circular array between the circular ring and the connecting ring. One end of the rotating shaft is fixedly connected to the center of the connecting ring, and the other end of the rotating shaft is rotatably connected to the side wall of the ash hopper. The circular ring is rotatably connected to the annular groove.

[0008] Furthermore, the upper end of the input pipe is provided with a protruding baffle that extends above the agitation structure.

[0009] Furthermore, the dust removal mechanism includes a dust collection box and a spiral structure. The dust hopper is connected and communicates with the dust collection box vertically. The spiral structure is rotatably connected to the dust collection box. The input end of the spiral structure is located outside the dust collection box, and the dust discharge port is located at the lower end of the dust collection box where one end of the spiral structure is located.

[0010] Furthermore, a motor is provided on the side of the dust collection box, and the output end of the motor is connected to the input end of the spiral structure.

[0011] Compared with the prior art, the advantages of this utility model are as follows: when gas backwashing is used to remove dust from the filter bag, the dust falls into the ash hopper below and is eventually discharged by the dust removal mechanism; during the gas backwashing and dust removal process, the dust can be kept loose in the ash hopper by manually rotating the stirring structure, so as to avoid the dust in the upper part of the ash hopper being too compact and unable to fall and be discharged smoothly.

[0019] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figure 1-5 As shown, a baghouse dust collector includes a dust collection box, a dust hopper 2, and a dust discharge mechanism connected sequentially from top to bottom. The dust hopper 2 has an input pipe 101 on its side and an output pipe 102 on the side of the dust collection box. The dust discharge mechanism has a dust discharge port 301 at its lower end. The dust hopper 2 narrows from top to bottom and has an agitation structure inside. One end of the agitation structure is rotatably connected to the input pipe 101, and the other end is rotatably connected to the side wall of the dust hopper 2. The input end of the agitation structure is located outside the dust hopper 2. The dust collection box contains filter bags for capturing dust. When gas backwashing is used to remove dust from the filter bags, the dust falls into the lower dust hopper 2 and is eventually discharged by the dust discharge mechanism. During gas backwashing and dust discharge, the agitation structure can be manually rotated to keep the dust loose in the dust hopper 2, preventing the dust in the upper part of the dust hopper 2 from becoming too compacted and unable to fall and be discharged smoothly.

[0021] In the above embodiment, an annular groove 11 is provided inside the input pipe 101. One end of the agitator is rotatably connected to the annular groove 11, providing a force point for the agitator and ensuring smooth rotation. The output end of the agitator is a hexagonal prism structure, which facilitates the installation and use of tools such as sockets and wrenches. The agitator consists of a circular ring 6, agitator blades 7, a connecting ring 8, and a rotating shaft 9. The agitator blades 7 have a blade-shaped cross-section, and there are multiple agitator blades 7 arranged circumferentially between the circular ring 6 and the connecting ring 8. One end of the rotating shaft 9 is fixedly connected to the center of the connecting ring 8, and the other end of the rotating shaft 9 is rotatably connected to the side wall of the ash hopper 2. The circular ring 6 is rotatably connected to the annular groove 11. The agitator has a cage-like design, which does not affect the smooth passage of dust and can also perform all-round agitation in the ash hopper 2, ensuring that the dust can be separated from each other. The blade-shaped agitator blades 7 can cut the dust, and can disperse compacted or clump-like dust, ensuring that the dust falls smoothly into the dust discharge mechanism. The upper end of the input pipe 101 is provided with a protruding baffle 10. The baffle 10 extends above the agitation structure to prevent dust from entering the annular groove 11 during the falling process and to prevent dust from affecting the rotation of the ring 6.

[0022] The dust removal mechanism includes a dust collection box 3 and a spiral structure 5. The dust hopper 2 is vertically connected to and communicates with the dust collection box 3. The spiral structure 5 is rotatably connected to the dust collection box 3. The input end of the spiral structure 5 is located on the outside of the dust collection box 3, and the dust discharge port 301 is located at the lower end of the dust collection box 3 where one end of the spiral structure 5 is located. The spiral structure 5 serves as a guide, conveying dust to the dust discharge port 301. A motor 4 is provided on the side of the dust collection box 3. The output end of the motor 4 is connected to the input end of the spiral structure 5, further improving the degree of automation. The input end of the spiral structure 5 and the input end of the agitation structure can be linked by adding a synchronous motion component, using the same power source to drive them, so that the spiral structure 5 and the agitation structure move synchronously, making operation more convenient.

[0023] Description of the working principle of this utility model:

[0024] When the air volume of the factory's dust removal system decreases significantly, or after a certain maintenance period, the bag filter needs to be cleaned. Cleaning is generally done by reverse gas washing. The removed dust falls into the dust hopper 2. After reverse gas washing, the dust is discharged from the dust outlet 301 by the conveying action of the spiral structure 5. Throughout the reverse gas washing and conveying process of the spiral structure 5, the stirring structure can be rotated to disperse and separate the dust, ensuring that the dust is loose and does not clump, and ensuring that the dust enters the dust collection box 3 smoothly and is discharged.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
