Problems solved by technology

Polyurethane filter The filter element of the air filter is made of soft, porous, spongy polyurethane with strong adsorption capacity. This air filter has the advantages of paper dry air filter, but its mechanical strength is low. It is used in car engines. more widely used in
The disadvantages of the latter two air filters are their short service life and unreliable operation under harsh environmental conditions

Embodiment 1

[0055] The filter material includes rattan core, rattan bark and poplar wood. The proportion of rattan bark is between 20% and 60%, the proportion of rattan core is between 30% and 50%, and the proportion of poplar wood particles is between 20% and 60%. Between 30%.

[0056] The first step is to separate the rattan bark and rattan core from the rattan. The rattan bark is made into plant fibers through processes including separation, opening, activation, and swelling. The rattan core and poplar are crushed into granules for future use.

[0057] In the second step, the plant fibers and granules obtained from rattan bark, rattan core and poplar are mixed with water and stirred to dissolve each other, and then dehydrated by a centrifuge.

[0058] In the third step, the dehydrated material is made into a fiber cloth through a process including layering and rolling, and a filter module is obtained after molding and cutting.

Embodiment 2

[0060] The filter material includes rattan core, rattan bark and poplar wood. The proportion of rattan bark is between 20% and 60%, the proportion of rattan core is between 30% and 50%, and the proportion of poplar wood particles is between 20% and 60%. Between 30%.

[0061] The first step is to separate the rattan bark and rattan core from the rattan. The rattan bark is made into plant fibers through processes including separation, opening, activation, and swelling. The rattan core and poplar are crushed into granules for future use.

[0062] In the second step, the plant fibers and granules obtained from rattan bark, rattan core and poplar are mixed with water and stirred to dissolve each other, and then dehydrated by a centrifuge.

[0063] In the third step, the dehydrated material is added with at least 30% cellulose acetate to the mixture to obtain a microfiltration filter material, which is made into a fiber cloth through a process including layering and rolling, and is ...

Embodiment 3

[0065] The filter material includes rattan core, rattan bark and poplar wood. The proportion of rattan bark is between 20% and 60%, the proportion of rattan core is between 30% and 50%, and the proportion of poplar wood particles is between 20% and 60%. Between 30%.

[0066] The first step is to separate the rattan bark and rattan core from the rattan. The rattan bark is made into plant fibers through processes including separation, opening, activation, and swelling. The rattan core and poplar are crushed into granules for future use.

[0067] In the second step, the mixture of plant fibers and granules obtained from rattan bark, rattan core and poplar is added to the mixture with 30% cellulose acetate, mixed with water, stirred and dissolved, and then dehydrated by a centrifuge.

[0068] In the third step, the dehydrated material is obtained as a microfiltration filter material, which is made into a fiber cloth through a process including layer laying and rolling, and a filte...

Abstract

The invention provides an automobile air filter, a filter element and an automobile. The filter element comprises an initial filtering layer, a main filtering layer and a micro-filtering layer, the initial filtering layer is formed by fiber cloth made of rattan bark, rattan cores and poplar filtering material in a compression molding mode; the main filtering layer is composed of a plurality of rattan core layers and cushion layers, each rattan core layer is formed in the mode that a plurality of rattan cores are arranged side by side, one cushion layer is arranged between every two rattan core layers, and the cushion layers are made of materials the same as those of the initial filtering layer in a tight compaction mode through a die; the micro-filtering layer is obtained by cutting the filter cloth obtained by mixing the rattan bark, the rattan cores and the cellulose acetate fiber materials, the main filtering layer in the middle is wrapped by the initial filtering layer and the micro-filtering layer, the hollow direction of the rattan cores of the main filtering layer is coincident with the air flowing direction, the axial adsorption characteristic of plants and the dot-matrix hole arrangement mode are adopted, three-level filtering is achieved, the filtering effect can be improved, environmental protection is achieved, and the service life of the air filter is prolonged; meanwhile, quality of air entering an engine is optimized, the air inlet amount is guaranteed, and abrasions to the engine are reduced.

Description

technical field [0001] The invention relates to the field of filtration, in particular to the purification and filtration of the air system of an automobile engine. Background technique [0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the chance of abrasion and damage. The main components of the air filter are the filter element and the casing. The filter element is the main filtering part, which is responsible for the filtration of gas, and the casing is the external structure that provides the necessary protection for the filter element. The working requirement of the air filter is to be able to undertake high-efficiency air filtration work, not to add too much resistance to the air flow, and to be able to work continuously for a long time. [0003] T...
