Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, and in particular to a dust removal device for a nano-dispersed alumina grinding workshop. Background Technology

[0002] Nano-dispersed alumina is a type of alumina particles with a size in the nanometer range. It possesses excellent physical and chemical properties and is widely used in materials science, catalysts, electronic science, and biomedicine. The preparation methods for nano-dispersed alumina include solid-phase, liquid-phase, and gas-phase methods. Solid-phase methods include mechanical, pyrolysis, and combustion methods. Mechanical methods involve grinding the raw material using a grinder, resulting in nano-alumina powder containing certain impurities. These impurities are then removed using chemical processes. Mechanical methods are simple and low-cost, hence their widespread use. However, they generate noise and dust pollution during actual operation. This dust, composed of alumina powder, not only worsens air quality in the grinding workshop but also leads to the waste of alumina powder. Therefore, developing a dust removal device for nano-dispersed alumina grinding workshops that can purify the air and reduce alumina powder waste is particularly necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a dust removal device for a nano-dispersed alumina grinding workshop, which has the advantages of purifying the air in the workshop and reducing the waste of alumina powder.

[0004] The technical solution adopted is as follows:

[0005] A dust removal device for a nano-dispersed alumina grinding workshop includes a base plate, a dust collection hood slidably mounted on the base plate, multiple dust collection branch pipes on the inner wall of the dust collection hood, a main pipe connected to each dust collection branch pipe inside the dust collection hood, and a steel wire hose connected to the main pipe. A dust collection tank is mounted on the outer side of the base plate, and the dust collection tank is equipped with a dust inlet pipe connected to the steel wire hose. A first valve is mounted on the dust inlet pipe. A mesh cylinder is mounted inside the dust collection tank, and a cloth bag is wrapped around the outside of the mesh cylinder. An exhaust pipe extending from the mesh cylinder to the outside of the dust collection tank is mounted on the exhaust pipe, and a bidirectional negative pressure fan is mounted at the end of the exhaust pipe. A dust discharge pipe is mounted at the lower end of the dust collection tank, and a second valve is mounted on the dust discharge pipe.

[0006] Preferably, the base plate is provided with multiple racks horizontally, and the dust collection hood is provided with multiple drive mechanisms, each drive mechanism including a gear, which meshes with a corresponding rack.

[0007] Preferably, the mesh cylinder is a cone shape that is smaller at the top and larger at the bottom.

[0008] Preferably, the lower end of the dust collection tank is funnel-shaped.

[0009] Preferably, a water tank is provided on the bottom plate below the dust collection tank, the water tank is filled with water, the dust discharge pipe is inserted into the water tank and extends below the liquid surface, and an exhaust window is provided at the top of the water tank.

[0010] Preferably, both the first valve and the second valve are electric ball valves.

[0011] Compared to existing technologies, the advantages are:

[0012] This invention utilizes a dust collection hood to cover the nano-dispersed alumina grinding equipment. A bidirectional negative pressure fan is activated to draw the dust generated during the grinding process into a dust collection tank and attach it to the surface of a cloth bag. After a certain amount of dust adheres to the surface of the cloth bag, the first valve is closed and the second valve is opened. The dust collection bag is connected to the dust discharge pipe, and the bidirectional negative pressure fan is rotated in reverse to blow the dust in the dust collection tank into the dust collection bag, thereby collecting the nano-alumina, reducing waste, and purifying the air in the grinding workshop.
