Abstract
The utility model discloses an electronic air filter, which is composed of a metal shell, a composite filter core and a high-voltage electrostatic generator, wherein the composite filter core is made of multiple layers of wire nets and an outer filter core and an inner filter core are integrally formed on a framework and form mutual electric conduction. The center part of the metal shell is provided with a fixed center air inlet pipe; a filter core assembly is sheathed on the center pipe, and is matched in the shell in a mode of insulation. The electrostatic generator is fixed on an outer shell body of the shell; a high-voltage negative electrode is connected with a filter framework by a high-voltage line, and a high-voltage positive electrode is connected with the shell; an electrostatic field is formed between the shell and the filter core, and dust in air can be attracted by charged current when passing. The electronic air filter has the advantages of ideal filtering effect and oil saving.
Description
Technical field:
The utility model relates to a kind of internal combustion engine part class: i.e. electrical air filter.
Background technique:
Present air-strainer, no matter secondary filtering, three grades of filterings mostly are the inertia oil bath types, often need more change engine oil in the middle of using, i.e. trouble waste again, and also the filtering effect is undesirable again.
Summary of the invention:
In order to overcome above-mentioned deficiency, the utility model provides a kind of electrical air filter, utilizes electrostatic field to inhale earth removal dirt.
The technological scheme that its technical problem that solves the utility model adopts is, loads onto the composite filter element of being made up of two filter cores in metal shell, makes shell and filter core that good insulation be arranged, and the logical respectively positive negative electricity of high pressure of going up; Between shell and filter core, will form electrostatic field like this, and make the dust of process electric field charged, held.
Profitable fruit of the present utility model is can save a large amount of machine oil, raising aeroscope.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the electrical schematic diagram of electrical air filter static-generator.
Fig. 2 is an electrical air filter embodiment sectional structural map.
Fig. 3 is that electrical air filter is overlooked cut-away view.
Among the figure 1, the insulated enclosure circle, 2, outer filter core, 3, the insulated enclosure pad, 4, inner filter core, 5, wing nut, 6, central intake pipe, 7, the insulated enclosure cover, 8, strainer cover, 9, the filter core framework, 10, high voltage wire, 11, shell, 12, static-generator, 13, power line.
Embodiment:
In Fig. 1, triode (2) resistance (3) is electrically connected by principle with transformer (4), produces self oscillations, goes out high-tension electricity (more than the 5000V) at the secondary induction of transformer (4), supplies with filter core and shell generation electrostatic field after diode (5) rectification.More than diode (5) the breakdown reverse voltage 2000V; Triode (2) 3DD type β value is selected more than 20; High-voltage capacitance (6) 2000PF, 2000V.
In the embodiment shown in Figure 2, outer filter core (2) adopts multilayer chain link fence structure with inner filter core (4), is combined to the assembly that becomes one on the framework (9); Put insulated enclosure circle (1) inner ring at the cylindrical of filter core assembly and put insulated enclosure cover (7), be sleeved on again on the interior central intake pipe of shell (11) (6), upward fill up insulated enclosure pad (3) on the circumferential end surfaces edge at filter core framework (9), tighten wing nut (5) with strainer cover (8) lid thereon; Filter core respectively becomes a utmost point, mutually insulated with shell.
Static-generator (12) is fixed on arbitrary place on the external casing of shell (11); Negative electricity is connected on the filter core tank bracket (9) by high voltage wire (10), and the high-voltage positive electrode electricity is that earth electrode is connected with the shell bonding, and power line (13) opens and closes with internal-combustion engine storage battery (1) and is connected.Filter core negative electrode and shell positive electrode constitute the high-voltage electrostatic field, realize electrostatic precipitation.
