Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation materials technology, specifically relating to a uniform powder feeding device for fiber felt. Background Technology

[0002] The fiber felt production system includes a fiber yarn opening machine, an air-jet web forming machine, a powder spreading device, a web laying machine, a compaction device, and a winding device, arranged in sequence. After the fiber yarn is opened and dispersed, it is spread onto the air-jet web forming machine to form a fiber web. Then, the powder spreading device evenly sprays nano-powder material onto the mesh belt. The powder spreading device usually uses a set of nozzles to evenly spray the powder, but due to uneven powder feeding, the amount of powder sprinkled is still uneven. Summary of the Invention

[0003] To address the problem of uneven powder delivery, this invention provides a uniform powder delivery device for fiber felt.

[0004] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows: A uniform powder feeding device for fiber felt includes a distribution cylinder and a bellows. The upper part of the distribution cylinder is a cylindrical body, and the lower part is a conical body. The top surface of the cylindrical body has multiple discharge ports evenly distributed, and the bottom of the distribution cylinder is provided with a support frame and a feed port. A horizontal distribution plate is provided inside the distribution cylinder, which divides the cylindrical body into upper and lower parts. The distribution plate has evenly distributed distribution holes. Each discharge port is connected to an air inlet of the bellows through a discharge pipe. An exhaust fan is provided inside the bellows, and the bellows is provided with multiple air outlets corresponding to the air inlets. Each air outlet is connected to a feeding pipe.

[0005] The equalizing cylinder of this utility model has a ventilation opening on the lower side of the equalizing plate, which is connected to a blower.

[0006] Preferably, the side of the equalizing cylinder is provided with two ventilation openings facing each other.

[0007] The opening ratio of the equal distribution plate described in this utility model is 10~20%.

[0008] Preferably, the aperture of the equalization plate is 5~20mm to ensure that the nanopowder is fully dispersed in the cylinder.

[0009] The equalizing cylinder of this utility model is provided with 6 discharge ports.

[0010] The beneficial effects of this utility model are as follows: 1. Under the action of the exhaust fan, the powder is first evenly distributed in the cylinder by the equalization plate, then evenly discharged from multiple outlets evenly distributed on the top surface, and finally fed to the powder-spreading device through multiple air outlets of the air box, so that the powder is evenly dispersed and conveyed by the air and then sprinkled. 2. Two ventilation openings are set opposite each other on the side of the equalization cylinder, so that the air rotates inside the equalization cylinder, and the powder can achieve a better dispersion effect.
