Description
Technical Field
The invention relates to the technical field of material accumulation hopper equipment, in particular to a split pneumatic double-layer valve for a material accumulation hopper.
Background
A pneumatic valve is generally installed at a lower portion of a hopper of a device for conveying residue or materials in a boiler, a dust collector, or the like. Usually, a double-layer cylinder is used for respectively controlling a valve, so that the internal air and the external air are locked when the material is discharged from the material collecting hopper, and the external wet and cold air is prevented from entering a flue or the inside of a dust remover to cause dewing. Because the valve plate aperture of pneumatic double-deck valve is great relatively, the trafficability characteristic of material is good, meets the difficult jam of bold material, so the lower part of many long-pending hoppers all uses and starts double-deck valve.
However, in practical application, the valves of a plurality of double cylinders are formed by combining two cylinders up and down, the installation height after combination can reach more than one meter, the problem of insufficient installation height space often occurs when the valves are installed on specific equipment, and meanwhile, in use, when the problems such as bearing damage occur, the operation during bearing replacement also needs larger equipment space, so that the equipment for installing and starting the double-layer valves is generally required to be redesigned and refitted to ensure the successful installation of the double-layer pneumatic valves, and resources and time are greatly wasted.

Detailed Description
As shown in fig. 1 to 3, the present invention includes a pair-open pneumatic double-deck valve for a bucket, which includes: the device comprises an air cylinder 3 and valves which are arranged in an upper layer and a lower layer, wherein the two valves are arranged in a shell 1 of a material collecting hopper and are positioned between an inlet 1-1 and an outlet 1-2; a material channel 2 is arranged in the shell corresponding to the port 1-1 and the outlet 1-2, and materials enter the material collecting hopper from the inlet 1-1 and leave the material collecting hopper from the outlet 1-2.
The valve comprises two split valve plates 4, the valve plates 4 are parallel to the horizontal sections of the inlet 1-1 and the outlet 1-2, and when the valve is specifically installed, the plane formed by the two valve plates 4 is matched with the horizontal section of the material channel 2 in shape, so that the material channel 2 is closed when the valve is in a closed state.
Each valve plate 4 is connected to one cylinder 3 through a transmission structure; the transmission structure includes: a transmission shaft 5 and a first connecting rod 7 and a second connecting rod 8 respectively fixed on the transmission shaft 5.
The cylinder 3 is arranged on the shell 1 through a mounting seat 3-1; each cylinder 3 controls the overturning of a valve plate 4 through a transmission shaft 5; the transmission shaft 5 is horizontally arranged on the shell 1 through a bearing seat 6; a cylinder 3 rod of the cylinder 3 is hinged with one end of a first connecting rod 7, the other end of the first connecting rod 7 is sleeved and fixed on the outer circumference of the transmission shaft 5, one end of a second connecting rod 8 is sleeved and fixed on the outer circumference of the transmission shaft 5, and the other end of the second connecting rod is fixedly connected with the central position of the bottom end face of the valve plate 4; the cylinders 3 on the same layer are arranged in parallel and opposite; the cylinder 3 and the bearing housing 6 are both disposed outside the housing 1, and the transmission shaft 5 passes through the housing 1 and is installed in the bearing housing 6 disposed outside.
As shown in fig. 1, when the cylinder 3 is started, one end of the first link 7 is pushed outwards, the first link 7 rotates to drive the transmission shaft 5 concentric therewith to rotate, and the transmission shaft 5 drives the second link 8 sleeved on the outer circumference thereof to rotate, thereby driving the valve plate 4 to rotate downwards with the transmission shaft 5 as an axis. The cylinders 3 of the same layer are arranged in parallel and opposite to each other, and the two valve plates 4 are rotated downward in opposite directions, respectively, so that the valves are opened. When the two cylinders 3 on the same layer are reversely started and the cylinder rod is contracted, the two transmission shafts 5 reversely rotate, the valve plates 4 respectively rotate upwards in opposite directions, and the cylinders 3 stop until the two valve plates 4 are positioned on the same horizontal line, so that the valves are closed.
Taking a QSF400 type cylinder as a driving cylinder as an example, when a single-opening valve is used on each layer, the overall height of the double-cylinder QSF400 pneumatic double-layer valve is 1350mm, while the combined double-layer starting valve is 850mm, and the installation height of the double-layer valve of the four cylinders is 500mm lower than that of the cylinder, thereby saving a large installation space.
And a sealing filler layer is arranged among the bearing seat 6, the transmission shaft 5 and the shell 1, and sealing is carried out through a sealing filler 9.
According to the invention, the upper layer valve and the lower layer valve of the double-layer valve are arranged in the shell 1, and the packing seal is arranged between the transmission shaft 5 and the shell, so that the sealing property is ensured, and further, the material passing through the material channel 2 is prevented from leaking. The cylinder 3 and the bearing seat 6 of the double-layer valve are arranged outside the shell 1, and when conveyed materials are high-temperature ash, the temperature cannot be conducted to the bearing, so that the bearing is protected from being damaged due to high temperature. Meanwhile, ash slag is prevented from entering the bearing due to the fact that the packing is arranged between the bearing seat 6 and the shell 1 for sealing, and the service life of the bearing is prolonged.
