Description

Air filter

Technical Field

The present invention relates to an air filter.

Background

Generally, the modified self-unloading ship can carry dry coal, ore and the like, and a large amount of dust is generated in the process of conveying goods through a belt. Therefore, for the health consideration of shipmen, the shipowner needs to install a dust removal device at the main air inlets (for example, the air inlet of the louver of the cabin blower and the air inlet of the louver of the built-in air conditioner) during the refitting, and generally, in order to achieve a good filtering effect, the water spray dust removal device is used firstly, but the installation of the water spray dust removal device needs a large occupied space, needs more additionally configured equipment (an electrical control box, a fresh water pump, a sewage collection cabinet, a fresh water pipeline and the like need to be added), and has a high equipment cost. According to actual conditions, the water spray dust removal device cannot be installed.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides an air filter, which meets the requirements of shipowners on smaller volume, convenient installation, convenient disassembly and good filtering effect of the air filter.

In order to achieve the purpose, the technical scheme of the invention is to design an air filter, which comprises a filter frame arranged at an air inlet of a shutter, wherein a detachable filter component is arranged in the filter frame, the filter component comprises a rigid material frame for replacing the filter component without detaching the filter frame, and the rigid material frame is arranged in the filter frame in a sliding manner. Due to the adoption of the rigid material frame, when the filter assembly needs to be replaced, only two side edges of the filter frame need to be opened, and then a new filter assembly is inserted, so that the filter assembly originally arranged in the filter frame can be pushed out.

The further technical scheme is that the filtering component comprises filtering cotton and stainless steel filtering nets arranged on two sides of the filtering cotton, and the hard material frame is fixedly arranged on the edges of the filtering nets; the filtration grade of the filter cotton is M5.

The further technical proposal is that a chute for sliding the rigid material frame is arranged in the filter frame; and a plurality of rollers for reducing the sliding of the rigid material frame are rotatably arranged in the sliding groove.

A further technical scheme does, the fixed filtration silver that sets up of tank bottom of spout, the groove lateral wall that filters the silver and be close to the spout sets up, and two groove lateral wall departments all are equipped with the filtration silver, and the filtration silver surpasss the notch setting of spout, surpasss the filtration silver of spout notch and is used for covering, seal whole shutter air inlet region with the filter screen cooperation completely. Therefore, the filter assembly can be conveniently replaced, and the movable filter assembly can be ensured to be still tightly filtered and can be fully covered due to the arrangement of the filter cotton sliver exceeding the chute notch after the filter assembly is inserted. In order to meet the requirements of shipowners on small size, convenient installation, convenient disassembly and good filtering effect of the air filter, a method of adding filter cotton (fixed by a stainless steel mesh) and a filter frame is designed. The selected filter cotton is C3-300, and the filtration grade is M5. The design of the filter screen and the filter frame adopts two design schemes of a side sliding type and a top mounting type according to different installation positions, the filter screen (a plurality of filter screens can be adopted according to the area of the ventilation opening) is embedded into the filter frame, and the air inlet area of the whole shutter is covered and sealed to filter the entering air. The design of the set of filtering device is used in the 'roller' self-unloading modified ship, and good effect is obtained. This provides an alternative to the later similar re-shipment of ships, where the owner of the ship needs to add an air filter, but where the installation space is limited.

The further technical proposal is that a rotating baffle used for clamping the filtering component is arranged on the frame edge of the filter frame in a rotating way.

The invention has the advantages and beneficial effects that: it is less to have satisfied the shipowner and required the volume to air filter, simple to operate, it is convenient to dismantle, the requirement that the filter effect is good compares in original dust collector in order to reach good filter effect, adopts water spray dust collector, and the required space that occupies of water spray dust collector installation is great, and the equipment that needs extra configuration is more, needs increase electrical control box, fresh water pump, sewage collection cabinet, fresh water pipeline etc. has avoided the great scheduling problem of its equipment cost of original mode. Due to the adoption of the rigid material frame, when the filter assembly needs to be replaced, only two side edges of the filter frame need to be opened, and then a new filter assembly is inserted, so that the filter assembly originally arranged in the filter frame can be pushed out. Not only can be convenient for change filtering component, owing to surpass the setting of the filtration silver of spout notch after inserting filtering component moreover, can guarantee that this kind of movable filtering component's form still can tight filtration, can the full coverage.
