Description

Technical Field

[0001] The utility model relates to the field of dust collectors, in particular to an energy-saving bag dust collector. Background Art

[0002] The bag dust collector can use filter bags to capture fine dust in the gas, filter the dust-laden gas, avoid directly discharging the dust into the external air, and recycle valuable dust to reduce production costs.

[0003] During the dust removal process, dust is trapped on the outer surface of the filter bag. As dust accumulates, airflow and dust removal efficiency decrease, necessitating cleaning. Filter bags can be cleaned by injecting high-pressure air into the bag, causing it to rapidly inflate and shake off the dust adhering to its outer surface. Filter bags are large, and to achieve this rapid inflating, a high-pressure airflow is required, resulting in high energy consumption and requiring improvement. Utility Model Content

[0006] An energy-saving bag dust collector comprises: a box body, a filter cloth bag, an air cloth pipe, an air cloth ring and a supporting frame, a partition is horizontally arranged in the box body to form an air outlet cavity above the partition and an air inlet cavity below the partition in the box body, the air cloth ring is arranged on the partition at intervals, the supporting frame is arranged at the bottom of the air cloth ring and extends downward to the air inlet cavity, the filter cloth bag is set on the outside of the support frame and is located in the air inlet cavity, the air cloth pipe extends from the outside of the box body to the air outlet cavity, and an air supply pipe corresponding to and connected to the air cloth ring is provided on the air cloth pipe, the supporting frame comprises several hollow steel pipes distributed in a circular array and extending vertically, the tops of the hollow steel pipes are respectively connected to the air cloth rings, and blowing holes are arranged at intervals on the upper and lower sides of the hollow steel pipe facing the filter cloth bag.

[0007] Wherein, an air intake pipe joint communicating with the air intake cavity is provided on one side of the box body.

[0008] Wherein, an air outlet pipe joint communicating with the air outlet cavity is provided on one side of the box body.

[0009] Wherein, a pulse valve is provided on the air supply pipe.

[0010] Wherein, a plugging head is provided at the bottom of the hollow steel pipe.

[0011] Wherein, an ash hopper is provided at the bottom of the box.

[0012] Wherein, a discharge valve is provided at the bottom of the ash hopper.

[0013] The beneficial effects of the utility model are: an energy-saving bag dust collector, the dust-containing gas enters the air inlet cavity through the air inlet pipe joint, and after being filtered by the filter bag, the clean gas enters the air outlet cavity and is finally discharged through the air outlet pipe joint. During maintenance, the compressed air in the air pipe can be sent into the air ring through the air supply pipe, and then the blowing hole on the hollow steel pipe is used to blow toward the inner wall of the filter bag, driving the filter bag to expand and shake outward. The diameter of the blowing hole is small and the air consumption is low, thereby reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following combination Figures 1 to 2 The technical solution of the present utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The energy-saving bag dust collector shown includes: a box body 1, a filter bag 2, an air distribution pipe 7, an air distribution ring 8 and a support frame 3. A partition 4 is horizontally arranged in the box body 1 to form an air outlet cavity 6 located above the partition 4 and an air inlet cavity 14 located below the partition 4 in the box body 1. The edge of the partition 4 is welded and fixed to the inner wall of the box body 1, and the structure is stable and airtight.

[0018] The air distribution ring 8 is arranged on the partition 4 at intervals, the support frame 4 is arranged at the bottom of the air distribution ring 8 and extends downward to the air inlet cavity 14, and the filter cloth bag 2 is sleeved on the outside of the support frame 4 and is located in the air inlet cavity 14. In this embodiment, four filter cloth bags 2 are used to work together, and the maintenance of each filter cloth bag 2 can be carried out in turn without affecting the dust removal work.
