The Question:
The star unloader is commonly used in the pneumatic output system. For the pressure output system or the negative pressure output system, the star unloader can evenly and continuously supply the material to the conveying pipe to ensure that the gas and solids in the pneumatic output pipe are relatively stable, so that the pneumatic conveying can work normally. At the same time, it can also isolate the upper and lower parts of the unloader.
However, the current discharge valve is inconvenient to disassemble and clean, especially when cleaning the internal impeller structure, it is very troublesome to disassemble.
Technical realization elements:
In order to achieve the above object, the utility model adopts the following technical scheme: a pull rod quick-release cleaning type discharge valve, including a housing, the top of the housing is provided with a material inlet, the bottom of the housing is provided with a discharge port, the left and right sides of the housing are provided with openings, the left and right sides of the housing are fixedly connected with the end cover 2 and the end cover 1 respectively, and the end cover 2 and the end cover 1 are connected to the rotating shaft through the bearing. setting;
1. The side of the rotating shaft and the end of the blade are fixedly connected with a limit ring, and the outer side of the limit ring is movably connected with a material baffle.
2. The end of the baffle plate close to the inside of the shell is provided with several protruding ribs, and the several protruding ribs are arranged in a circular array, and the end of the baffle plate away from the inside of the shell is set as a smooth surface.
3. It also includes: a motor, the output end of the motor is fixedly connected to a reducer, and the output end of the reducer is connected to one end of the rotating shaft in transmission.
4. Both the top of the feed port and the bottom of the discharge port are fixedly connected with connecting flanges, and the ends of the connecting flanges are provided with connecting holes.
5. The connection between the rotating shaft and the end cover 1 adopts an air-tight structure, and the connection between the rotating shaft and the end cover 2 adopts an air-tight structure.
6. An oil-water separator is connected in series on the air circuit of the air-tight structure.
7. The outer surfaces of end cover 1 and end cover 2 are provided with protruding frames, and the bearings are connected to the inner sides of the protruding frames.
Beneficial effect:
1. Compared with the prior art, this kind of pull rod quick-release cleaning type unloading valve connects the end cover 1 and the end cover 2 through screws on both sides of the shell, and then connects the impeller structure to the end cover 1 and the end cover 2 through bearings. When disassembling, one end cover is completely removed, and the shell can be quickly removed, and the impeller structure can be easily cleaned, which is more convenient to use.
2. Compared with the prior art, the pull rod quick-release cleaning type unloading valve is equipped with a baffle plate structure, which can prevent the material from directly contacting the side wall of the shell, prevent debris from entering the connection gap between the rotating shaft and the bearing, and accelerate the wear of the rotating shaft. The design of this structure can increase the cleaning cycle of the unloading valve, reduce the number of cleanings, and is more convenient to use.
1. Shell; 2. Feed inlet; 3. Discharge port; 4. Connecting flange; 5. End cover one; 6. End cover two; 7. Reducer; 8. Motor; 9. Air seal structure; 10. Oil-water separator;
Working principle: When in use, connect the feed inlet 2 to the upper feeding pipe, and connect the outlet 3 to the lower feeding pipe. The material falls by its own weight and fills the gap between the blades 12. When the rotating shaft 11 rotates, it drives the blades 12 to rotate the material between them. When the opening between two adjacent blades 12 is downward, the material will fall down by gravity to achieve the purpose of conveying the material.
When the device is disassembled and cleaned, the end cover 1 is completely disassembled, and then the housing 1 is pulled outward to complete disassembly and cleaning, which is convenient to use.
