Description

TECHNICAL FIELD

[0001] The present application relates to the field of the structure of the special equipment for the vacuum pipeline garbage collection system, in particular to a bottom valve in a vacuum garbage collection system. BACKGROUND

[0002] There are many types of pipeline valves in the vacuum pipeline garbage collection system, and the structures of these valves are quite different due to different installation positions. The bottom valve is designed for high-rise garbage disposal, and the valve is designed at the lower opening of the garbage temporary pipeline at the bottom layer of the vertical pipeline. The lower opening of the valve is connected with the horizontal pipeline of the system. Due to the long distance from the high-rise disposal opening, the valve needs to withstand the impact force of the garbage falling downward. Since the working environment of the valve is very harsh, the service life is also a very important indicator. Therefore, simply thickening the valve plate is not enough. A scientific design and good control method are needed to prolong the service life. The existing bottom valve is designed to be too heavy, and the reason is that the valve structure is unreasonable and unscientific.

[0003] Therefore, those skilled in the art need to change the structure of the bottom valve to overcome the above-mentioned defects. CONTENT OF THE INVENTION

[0028] like Figures 1-4 As shown, a bottom valve in a vacuum waste collection system includes a valve body, a material inlet obliquely opened inside the valve body, and a valve plate 3 rotatably disposed at the material inlet and located inside the valve body. The upper end of the valve plate 3 is rotatably connected to the valve body, and a crankshaft 7 is connected to the middle of the valve plate 3. At least one end of the crankshaft 7 extends out of the valve body, and a drive mechanism for driving the crankshaft 7 to rotate is provided on the outside of the valve body.

[0029] In the above structure, the valve plate 3 is rotatably disposed inside the valve body. It is not only small in size, but also provides good support while the crankshaft 7 is connected to the middle of the valve plate 3, so that the valve plate 3 can rotate. This allows the valve plate 3 as a whole to withstand the impact force when high-rise garbage falls. In addition, since the material inlet is inclined and the upper part of the valve plate 3 rotates, the angle between the valve plate 3 being closed and open is less than 90°. Therefore, when the valve plate 3 is open, neither the valve plate 3 nor the crankshaft 7 will occupy too much space inside the valve body.

[0030] The valve body adopts a split design, that is, the valve body includes an upper valve body 1 and a lower valve body 2 fixedly connected to the upper valve body 1. The material port is opened between the upper valve body 1 and the lower valve body 2. The upper valve body 1 and the lower valve body 2 are connected by a flange. In addition, for convenient maintenance, an inspection door 16 is movably provided on one side of the valve body. The inspection door 16 can be rotatably connected or slidably connected. It is mainly used for maintenance and inspection of the valve plate 3, crankshaft 7, valve plate shaft 14, etc. inside the valve body.

[0031] The valve plate 3 and the valve body are rotatably connected via a valve plate shaft 14. A valve plate bushing 15 is fixedly installed on the valve plate 3 to cooperate with the valve plate shaft 14. To ensure convenient valve assembly and maintenance, the valve plate bushing 15 is designed with a segmented structure. The inner diameter of the valve plate bushing 15 and the valve plate shaft 14 have an adjustable clearance. When the valve plate 3 rotates, the valve plate shaft 14 does not rotate with the valve plate 3. Specifically, for the convenience of valve production and assembly, and also for the convenience of equipment maintenance, the middle part of the valve plate shaft 14 is cylindrical, and the two ends of the valve plate shaft 14 are rectangular. A positioning seat is fixedly installed on the valve body and fixedly connected to the two ends of the valve plate shaft 14. In addition, in order to limit the position of the valve plate 3 when it is open, a limiting baffle 12 is also fixedly installed in the valve body to limit the rotation position of the valve plate 3. The limiting baffle 12 is set at the upper end of the valve plate 3, thereby ensuring that the valve plate 3 is in a vertical state when it is open, reducing the space occupied in the pipeline and facilitating the material to fall from the material outlet.

[0032] Both ends of the crankshaft 7 extend out of the valve body, both ends of the crankshaft 7 are connected with the driving mechanism, through both sides synchronous driving valve plate 3, valve plate 3 rotates smoothly, and reduces the wear of valve plate shaft 14, in addition, in order to realize the adjustable driving force, the driving mechanism includes the cylinder 4 which is rotatably connected with the valve body, the end of the piston rod of the cylinder 4 is rotatably connected with the cylinder crankshaft 6, the cylinder crankshaft 6 is fixedly connected with the end of the crankshaft 7.

[0033] Both ends of the crankshaft 7 and the valve body are provided with connecting structure, the connecting structure includes bearing seat 8 which is fixedly arranged on the valve body, the crankshaft 7 and the bearing seat 8 are connected through roller bearing 9, plane bearing 10 and stop nut 11, the roller bearing 9 and the plane bearing 10 are arranged on the inner and outer sides of the bearing seat 8 respectively, and then the bearing seat 8, the roller bearing 9 and the plane bearing 10 are limited by the stop nut 11, at the same time, the end surface of the cylinder crankshaft 6 and the crankshaft 7 is fixed by fastener, that is, the connection of the two is realized.

[0034] In order to make the valve plate 3 have better bearing, the valve plate 3 includes valve plate 3 frame, valve plate 3 flat plate which is fixedly arranged on the valve plate 3 frame, a plurality of reinforcing ribs are arranged between the valve plate 3 frame and the valve plate 3 flat plate, the upper surface of the valve plate 3 flat plate is fixedly provided with soft pad layer 13, the impact force can be reduced by arranging the soft pad layer 13, and the damage to the material and the valve plate 3 is reduced.

[0035] The above only for the preferred embodiment of the present application, and does not limit the present application, for those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
