Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic transportation, in particular to an electrostatic self-suspended pneumatic conveying and feeding device. Background Art

[0002] Pneumatic conveying, also known as airflow conveying, utilizes the energy of airflow to transport granular materials along the airflow within a closed pipeline. It is a specific application of fluidization technology. Pneumatic conveying devices have a simple structure and are easy to operate. They can convey materials horizontally, vertically, or at an angle. During the conveying process, they can also perform physical operations such as heating, cooling, drying, and airflow classification, as well as certain chemical operations. Compared to mechanical conveying, this method consumes more energy, is more susceptible to particle breakage, and is also susceptible to abrasion of the equipment.

[0003] In the prior art, when some pneumatic conveying devices use exhaust fans to supply air into the device, powdered or granular materials contain moisture and are easily adhered to the inner wall of the feed pipe, affecting the use of the device and reducing its service life. Therefore, it is very necessary to propose an electrostatic self-suspending pneumatic conveying feeding device. Utility Model Content

[0012] Furthermore, a hole is opened on the surface of the discharge pipe, and a rotating shaft is movably connected in the hole.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model removes impurities in the gas through the filter, and then the blower conveys the gas to the conveying pipe. By opening the valve, the material enters the dryer to reduce the moisture in the material. Then the material enters the conveying pipe through the rotary feeder. The positive and negative plates in the conveying pipe make the material suspended in the conveying pipe to prevent the material from adhering to the inner wall of the conveying pipe. The material is conveyed to the storage bin through the gas, thereby completing the material transportation and improving the practicality of the work.

[0015] 2. The utility model sets a level meter. When the material in the feed bin is insufficient, the level meter at the bottom of the feed bin will issue a prompt, so that the material can be added in time to avoid interruption of material transportation. When the material is placed in a certain position, the level meter at the upper end will issue a prompt, thereby realizing the addition of materials and improving work safety.

[0016] 3. The utility model cooperates with the feed bin, valve and discharge pipe. When material transportation is required, the cylinder in the valve drives the second roller on the second movable plate to slide on the first movable plate, so that the first roller slides along the arc plate, and then the arc plate drives the rotating shaft to rotate, and the rotating shaft drives the valve cover to rotate, thereby realizing the opening of the valve and then realizing material transportation, thereby improving the reliability of work.
