The utility model discloses a structure is like this: a opposed pneumatic double-deck valve for an accumulation hopper, comprising: an air cylinder and a valve which are arranged in an upper layer and a lower layer,
the two valves are arranged in the accumulation hopper shell and positioned between the inlet and the outlet;
the method is characterized in that:
said valve comprising two split valve plates parallel to the horizontal cross-section of said inlet and outlet ports, each of said valve plates being connected to one of said cylinders by a transmission structure;
the transmission structure includes: the first connecting rod and the second connecting rod are fixed on the transmission shaft respectively;
the transmission shaft is horizontally arranged on the shell through a bearing seat; a cylinder rod of the cylinder is hinged with one end of the first connecting rod, the other end of the first connecting rod is fixedly connected with the transmission shaft, one end of the second connecting rod is fixedly connected with the transmission shaft, and the other end of the second connecting rod is fixedly connected with the bottom end surface of the valve plate;
the cylinders on the same layer are arranged in parallel and oppositely;
the cylinder and the bearing seat are both disposed outside the housing.
It is further characterized in that:
and a sealing filler layer is arranged among the bearing seat, the transmission shaft and the shell.
The utility model provides a long-pending hopper is with to open pneumatic double-deck valve, it constitutes the valve through the valve plate that runs from opposite directions, compares with current veneer valve, and the valve height reduces, and two cylinders are parallelly arranged in the casing outside respectively, has reduced the height of every individual layer valve on the whole, and then has reduced the required height of the whole installation space of double-deck valve; meanwhile, the cylinder and the bearing are arranged outside the shell, so that the possibility of damage to the equipment due to reasons such as material temperature is reduced, the cylinder and the bearing seat arranged outside the shell are easier to maintain during maintenance, and the difficulty in installation and maintenance of the equipment is reduced on the whole.

Detailed Description
As shown in fig. 1-3, the utility model discloses a long-pending hopper is used to open pneumatic double-deck valve, it includes: the two valves are arranged in the shell 1 of the material collecting hopper and are positioned between the inlet 1-1 and the 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 cross sections of the inlet 1-1 and the outlet 1-2, and when the valve is installed, the plane formed by the two valve plates 4 is matched with the horizontal cross 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.
Use QSF400 type cylinder as driving actuating cylinder for example, when every layer uses the valve of a single division, the whole height of double-cylinder QSF400 pneumatic double-deck valve is 1350mm, and uses the utility model discloses a to open start double-deck valve, the mounting height after the combination is 850mm, and the double-deck valve mounting height ratio of four cylinders has been lowered 500mm than the mounting height of cylinder again, has saved very big installation space.
And a sealing filler layer is arranged between the bearing seat 6, the transmission shaft 5 and the shell 1 and is sealed by a sealing filler 9.
The utility model discloses in, the upper and lower two-layer valve of double-deck valve all establishes in the inside of casing 1, is equipped with the packing between transmission shaft 5 and casing and seals, ensures the leakproofness, and then ensures that the material that passes through can not take place to leak in the material passageway 2. 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.
