Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust collectors, and specifically, to a dust storage bin of a bag dust collector. Background Art
[0002] Dust collectors are divided into dry dust collectors and wet dust collectors. Dry dust collectors generally are equipped with a dust storage bin for storing ash. If the dust storage bin is in a hopper shape, it is called a dust hopper. With the continuous use of the bag dust collector, the amount of accumulated dust in the dust storage bin of the dust collector increases, and there may be a problem of dust bridging in the dust hopper of the bag dust collector. When checking the outlet of the ash discharging device or the ash conveying device during the operation of the ash discharging device, if the amount of discharged dust is small or no dust is discharged at all, there may already be a problem of dust bridging in the dust hopper.
[0003] In addition, after the dust gets damp, it often adheres to the inner surface of the dust hopper of the bag dust collector. During the operation of the dust collector, the temperature fluctuation makes the adhered dust accumulate thicker and harder. Some dust may even form hard gullies by caking, which not only hinders the discharge of dust, but also corrodes the dust hopper. Summary of the Utility Model
[0004] Therefore, the utility model provides a dust storage bin of a bag dust collector to overcome the above problems existing in the prior art.
[0005] The technical solution of the utility model is as follows:
[0006] A dust storage bin of a bag dust collector includes a main body, an air inlet, an ash discharge port and an outer wall surface knocking structure. The main body is a hollow hopper shape with a wider top and a narrower bottom. The air inlet is arranged on the side surface of the main body, the ash discharge port is arranged at the bottom end of the main body, and the outer wall surface knocking structure is arranged on the outer side surface of the main body. The outer wall surface knocking structure includes a hammer, a rotating shaft seat, a motor seat, a motor and a spiral tooth. The hammer includes a hammer head and a hammer rod. The hammer head is cylindrical. A shaft hole is arranged in the middle of the hammer rod along the radial direction of the hammer rod. A rotating shaft is inserted into the shaft hole, and the rotating shaft is arranged on the rotating shaft seat. The rotating shaft seat is fixed on the outer wall surface of the main body. The tail of the hammer rod is in a round cake shape. A blind hole for accommodating a spring and facing the outer wall surface of the main body is arranged between the tail of the hammer rod and the shaft hole. A pre-compressed spring is arranged between the blind hole and the outer wall surface of the main body. The motor seat is arranged close to the tail of the hammer rod. The motor is arranged on the motor seat. A spiral tooth is arranged at the output end of the motor. The spiral tooth is located above the round cake-shaped tail of the hammer rod and is in contact and cooperation with the round cake shape.
[0007] As a preferred implementation manner, the whole hammer head or only the hammering contact part of the hammer head is made of a soft material, and the soft material is rubber or plastic.
[0008] As a preferred embodiment, a plurality of reinforcing ribs are provided on the outer wall surface of the main body, and the reinforcing ribs are respectively arranged along the vertical and horizontal directions.
[0009] As a preferred embodiment, a dust discharge valve is provided at the ash discharge port, and the dust discharge valve is a star dust discharge valve.
[0010] As a preferred embodiment, a maintenance port is formed on the side surface of the main body, and a maintenance door that can be opened is provided outside the maintenance port.
[0011] The working principle and beneficial effects of the present utility model are as follows:
[0012] For the dust storage bin of the bag filter provided by the present utility model, when in use, the dust-containing air flow enters from the air inlet, and the falling dust falls into the main body and is discharged through the ash discharge port. When there is a situation such as dust bridging or adhesion of the dust in the main body, or when each ash discharge is completed, the motor can be energized. After being energized, the hammer continuously hammers the outer wall surface of the main body to shake off the adhered dust or the dust bridge formed by the dust, so as to smooth the ash discharge process and slow down the corrosion of the main body.
