Description

Technical Field

[0001] The utility model relates to the field of bag dust collectors, in particular to a dust discharging device at the bottom of a bag dust collector. Background Art

[0002] The bag dust collector uses a fan to suck dust-containing gas into the tank body and make the dust adhere to the bags. When the dust on the bags reaches a certain amount, it is necessary to pulse gas into the bags to make the bags expand and vibrate, and vibrate the dust attached to the bags into the ash hopper under the tank body. When the ash in the ash hopper accumulates to a certain amount, it is discharged through the butterfly valve.

[0003] The patent application with announcement number CN220194279U proposed in the prior art has scientifically and rationally improved the original ash discharge mechanism, and a dual-axis motor, an eccentric block, an air hood, an air jet bar and an air pipe are arranged on the ash discharge mechanism. When the dual-axis motor is energized, the eccentric block and the turbine blades can be driven to rotate synchronously. The rotating eccentric block can make the manual ash discharge valve produce reciprocating vibration, which can accelerate the discharge of dust through the manual ash discharge valve, and the rotating turbine blades can quickly transport the outside air into the air jet bar through the air pipe, thereby blowing the dust in the ash discharge hopper for ash discharge treatment. This structure can carry out comprehensive auxiliary discharge treatment on the dust accumulated between the ash discharge hopper and the manual ash discharge valve, effectively reducing the workload and difficulty of the operator using the ash discharge mechanism to discharge the ash, thereby improving the efficiency and quality of the ash discharge operation of the ash discharge mechanism.

[0004] By scientifically and rationally improving the original sealing plate outside the manhole, a rotating frame, a limit buckle block, a rotary block, an outer stud and an inner spiral button are set between the ash discharge hopper and the sealing plate. The original sealing hole structure is shown in Figure 4, which is installed and fixed to the manhole by multiple fasteners. Tools are required during its installation and removal process. The entire installation and removal operation is less convenient and efficient. For the improved sealing hole structure, the inner spiral button is rotated forward to separate from the outer stud, and the rotary block is rotated counterclockwise to remove the limit buckle block, so that the sealing plate can be unscrewed from the outside of the manhole. This structure increases the workload and difficulty of installing or removing the sealing plate from the manhole. Compared with the original sealing hole structure, it has the characteristics of convenient installation and removal and high efficiency, thereby facilitating the operator to perform inspection and maintenance operations inside the ash discharge mechanism during actual use.

[0005] However, in order to facilitate the cleaning of the dust inside, the current dust removal device has an operation port on the surface for operation. However, the size of the operation port is relatively limited, making it difficult to completely clean the dust inside the device.

[0006] Therefore, it is necessary to provide a dust discharge device at the bottom of a bag filter to solve the above technical problems. Utility Model Content

[0009] An ash feeding hopper, wherein a connecting assembly is provided at the bottom of the ash feeding hopper;

[0010] A disassembly bucket, the disassembly bucket is arranged below the connecting assembly, and a valve is installed below the disassembly bucket;
