Description

A kind of oblique plug type ash unloading valve

technical field

The utility model belongs to the technical field of dust collectors, and in particular relates to an oblique plug-in ash discharge valve for dust discharge of dust collectors.

Background technique

At present, most of the ash unloading valves used in dust collectors are manual plug-in valves. Conventional manual flapper valve is driven by hand plugging or turning the hand wheel to move the flapper along the horizontal direction repeatedly, so that the dust in the ash hopper falls into the ash bucket to achieve the opening and closing function. It has the characteristics of simple and compact structure, light and flexible operation, easy installation and disassembly, and is widely used.

However, due to the structural characteristics of the gate valve itself, there is a certain gap between the gate plate and the upper and lower plates, and a large amount of dust is easy to accumulate, resulting in difficult movement of the gate plate, and when the gate valve is opened, a large amount of dust along the The gap in the middle is brought out, causing the dust to leak out and scatter around, which not only pollutes the work and the surrounding environment, but also poses a threat to the health of the operating workers.

Further, the inclination angles of the upper board 21 , the middle board 22 and the lower board 23 are 10°-20°.

In the present invention, the pull rod 26 is arranged parallel to the inserting plate 24 and protrudes from a higher part of the valve body 25 .

Further, a connection block 29 is provided at the bottom of the insert board 24 to connect with the pull rod 26 .

Further, the pull rod 26 is connected to the connection block 29 through a Y-shaped joint 27, one end of the Y-shaped joint 27 is fixedly connected to the pull rod, and the other end is hinged to the connection block through a hinge.

The utility model adopts the plug-in valve of the above-mentioned technical scheme, and the valve plate and the plug-in board of the valve body are both inclined. The opening of the lower plate falls into the ash bucket, effectively avoiding the accumulation of dust in the gap between the valve plate and the inserting plate, prolonging the service life of the ash discharge valve, and adding Sealing rings and sealing strips reduce the chance of dust leakage.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Example

Referring to Fig. 1, the ash unloading valve adopts a gate valve 2, which is arranged between the cone pipe 1 of the dust collector and the ash bucket cover plate 31 of the ash bucket 3.

Referring to Fig. 2, the flapper valve 2 has three valve plates that are overlapped and connected together, which are respectively the upper plate 21, the middle plate 22 and the lower plate 23, and the upper plate 21, the middle plate 22 and the lower plate are fixedly connected as a whole. 23 is obliquely arranged on the valve body 25 with an inclination angle of 10°-20°, wherein the upper plate 21 opens at a lower position and is fixedly connected with the outlet at the bottom of the tapered pipe 1, and the corresponding position of the lower plate 23 is also open and passes through The inner cavity of the valve body 25 is connected to the entrance on the ash bucket cover plate 31, and the middle plate 22 is a frame-shaped splint, which encloses the movable space of the inserting plate 24 with the upper plate and the lower plate. Referring to Fig. 3, the upper plate 21, the middle plate 22 and the lower plate 23 are fixedly connected by bolts, and a sealing strip is provided between two adjacent plates, and the inserting plate 24 is arranged on the upper plate 21, the middle plate 22 In the cavity enclosed by the lower plate 23, its thickness is equivalent to that of the middle plate 22. The inserting plate 24 is connected with a pull rod 26 protruding from the valve body 25 , the pull rod 26 is arranged parallel to the inserting plate 24 and protrudes from a higher position of the valve body 25 . A sealing ring 29 is provided between the pull rod 26 and the valve body 25 .

Preferably, a connection block 29 is provided at the bottom of the inserting plate 24 to connect with the pull rod 26 to avoid direct contact with dust at the connection. The pull rod 26 is connected to the connecting block 29 through a Y-shaped joint 27. One end of the Y-shaped joint 27 is fixedly connected to the pull rod, and the other end is hinged to the connecting block through a hinge shaft. A certain degree of hinged connection can ensure the smooth operation of the pull rod when the plug-in board is not running smoothly. smooth.

The ash bucket 3 utilizes the ash bucket hoisting mechanism to put it on the top, and is closely attached to the ash bucket cover plate 31, and a sealing strip is pasted in the middle to ensure that the dust does not leak out when falling ash. When unloading the ash, pull the pull bar 26 to the upper right direction, and simultaneously drive the Y-shaped joint 27 to move together. The Y-shaped joint 27 and the inserting plate 24 slide upwards to the right along the inner cavity surrounded by the valve plate. At this time, the dust deposited in the conical pipe 1 falls and falls into the ash bucket 3 through the valve body of the ash discharge valve to realize the ash discharge valve. on. At this time, due to the characteristics of the dust, the fine dust falling into the ash bucket 3 rises and fills the cavity of the valve body 25 connected to the entire lower plate 23. A sealing ring 28 is equipped between the valve bodies to effectively prevent dust from leaking out of the gap.

After the ash unloading is completed, the pull rod 26 is put down, and under the action of its own weight, the pull rod drives the Y-shaped joint 27 and the inserting plate 24 to slide down to the lower left of the inner cavity of the valve plate, and the openings on the upper and lower plates are closed, and the ash unloading valve closure.

Those of ordinary skill in the art should understand that: the above are only specific embodiments of the utility model, and are not intended to limit the utility model. Any modifications, equivalent replacements, Improvements and the like should all be included within the protection scope of the present utility model.
