Description

Cyclone device in the air-intake of combustion engine pipeline

Technical field

The invention belongs to the cyclone device in a kind of air-intake of combustion engine pipeline.

Background technique

Induction system of internal combustion engine generally is made of suction tude, air-strainer and inlet manifold of IC engine, and the Cress of gas is all born by air-strainer, and the every 10000km of air cleaner cartridge just must clean or change generally speaking; But under dust big (many) or comparatively moist working environment, work, just must clean or change about every 2000km.Rainy day particularly, because air-intake negative-pressure effect inspiration is the rainwater particulate partly, cause moist or early stage damage of air cleaner cartridge, moist or the early stage damage of air cleaner cartridge makes the air inflow of gas handling system and air inlet quality not reach the requirement of internal-combustion engine proper functioning, the power character of internal-combustion engine and fuel economy can not be effectively played, even cause internal-combustion engine to damage in early days.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, the cyclone device in a kind of air-intake of combustion engine pipeline is provided, to solve the problem in the present induction system of internal combustion engine.

The specific design scheme is: the cyclone device in the air-intake of combustion engine pipeline mainly is made of the leading portion suction tude that is connected with the combustion air cleaner front end, cyclone leaf fan, back segment suction tude; Cyclone leaf is fanned in the back segment suction tude of packing into, and cyclone leaf fan lower end surface installs to the limit dais of lumen wall, and the leading portion suction tude is inserted the limit dais of back segment suction tude to leading portion suction tude inwall; Be shaped on dust discharge rhone and dust discharge drainage channel in the back segment suction tude inner chamber; Wherein the cyclone blade number is 8, and the spiral angle of blade is 35 °-42 °, and all in same plane, blade diameter is identical with the back segment suction tude inner diameter values of band dust discharge rhone and dust discharge drainage channel for the end face of 8 blades; Be evenly equipped with 4 attachment holes by 90 ° of angles on the circumference on the back segment air inlet tube wall in the same plane, inwall is manufactured with cyclone blade assembling limit dais and dust discharge rhone, and limit dais to dust discharge groove bottom height is generally 120-150mm.Cyclone blade diameter and dust discharge rhone width are made in 7: 1 ratio.There is the dust discharge drainage channel back segment suction tude outer wall lower end, at dust discharge drainage channel outlet section outer wall the fixing caulking gum dust-exhausting bag of clip is arranged.

Cyclonic separation blade of design in the tracheae of combustion air cleaner front end will enter ducted rainwater, dust and utilize the inertial separation principle to separate; The tracheae bottom design has dust discharge rhone and dust discharge drainage channel, and rainwater, dust that separation vane is separated gather eliminating; The dust discharge drainage channel leads to atmosphere end and seals with the rubber dust-exhausting bag, and the rubber dust-exhausting bag mainly is and atmospheric isolation; The inner-walls of duct design has cyclone blade assembling limit dais, is the rigging position of cyclonic separation blade in tracheae.

During internal combustion engine; cyclone device makes the air in the admission line; the mixture of dust and moisture passes through back being become by straight line motion of this device and rotatablely moves; because dust and moisture granular mass are bigger; utilize the inertial separation principle to allow dust and moisture particle enter the dust discharge rhone along the tube wall of admission line; outside dust discharge rhone device discharge tube; thereby to entering the air purification of air-strainer; protect filter core simultaneously; reach and surpass the internal-combustion engine required cleaning; dry air has been eliminated because dust; moisture content makes the internal-combustion engine premature wear; the infringement of scuffing of cylinder bore.

Improve the turbidity test and the degree of dryness of the gas that enters air-strainer, the present invention has designed that the mixture of dust and moisture separates in the good air of a kind of simple in structure, low cost of manufacture, functional reliability, discharger.

Apparatus of the present invention technique effect is embodied in the following aspects:

1. this apparatus structure is simple, easy to manufacture and cost is low, by in the admission line of air-strainer inlet end, install cyclonic separation, discharger additional and to the admission line length dimension design adjust, can realize exchanging at fit on intrinsic suction tude.

2. this device can effectively come out dust in the mixture of flow air, dust and moisture in the admission line and moisture particle separation, improve the air cleanliness and the degree of dryness that enter air-strainer, eliminated the infringement that makes internal-combustion engine premature wear, scuffing of cylinder bore owing to dust, moisture content simultaneously.

3. before this device is assemblied in the induction system of internal combustion engine air-strainer, air, dust and the moisture that enters air-strainer is carried out just separating, improve the gas turbidity test enter air-strainer, thereby improve the working life of air-strainer and internal-combustion engine and give full play to the power character and the fuel economy of internal-combustion engine.

4. this device can also be generalized to the industry beyond the automobile according to the extensive use of internal-combustion engine, as engineering machinery etc.
