Description

Empty filter water trap of oil bath formula

Technical Field

The utility model belongs to the technical field of heavy automobile parts, specifically speaking are empty filter water trap of oil bath formula.

Background

The air filter is a device which collects dust from gas-solid two-phase flow through the action of a porous filter material and purifies the gas. The air with low dust content is purified and sent into the room to ensure the technological requirement of clean room and the air cleanliness in the common air-conditioning room.

The oil bath type air filter uses oil and metal wires as main filter materials. The principle is as follows: the air containing impurities passes through the oil pan, so that the impurities in the air are in contact with the oil and are attached to an oil film. The air then passed through a wire filter layer. So that the impurities wrapped by the oil film are adhered in the metal wire. The air is filtered at the first stage, and the air after rough filtration enters a main filter element (paper) of a filter for fine filtration and then enters an engine for acting. The air filter is simple in structure and convenient to maintain, and is suitable for vehicles with severe driving conditions in emergency situations, such as heavy-duty automobiles and the like.

To installing oil bath formula air cleaner's heavy automobile additional, the vehicle is at rain, snow day gas during operation, the rainwater easily accompanies the air or sees through air intake system connection position entering oil bath formula air cleaner, and gather at the oil pan, current oil bath formula air cleaner is mostly airtight structure, no dewatering design, rainwater is gathered too much in the drain pan, the liquid level uprises, the air intake system resistance increases, the rainwater is inhaled air intake system in a large number easily, cause the filter core to become invalid, cause the engine to damage unusually when serious.

SUMMERY OF THE UTILITY MODEL

Mostly be airtight structure for solving oil bath formula air cleaner now, do not have the dewatering design, the rainwater is gathered too much in the drain pan, and the liquid level uprises, and the air intake system resistance increases, and the rainwater is inhaled air intake system in a large number easily, causes the filter core inefficacy, causes the problem of engine abnormal damage when serious, the utility model provides an air cleaner water trap of oil bath formula.

The utility model discloses a realize through following technical scheme.

The oil bath type water removing device for the air filter comprises an air filter body, an inclined air inlet pipe is arranged on the upper portion of the air filter body, a water dividing pipe is arranged inside the air inlet pipe, an annular water collecting cavity with a closed bottom is formed between the water dividing pipe and the air inlet pipe, and a drain pipe with a check valve is arranged at the bottommost end of the water collecting cavity. At empty filter body during operation, intake pipe department is negative pressure state, the external pipeline coaxial with the intake pipe in intake pipe upper portion, when having the rainwater in the pipeline, because the intake pipe is the slope form, moisture can flow into the chamber of catchmenting along the intake pipe downside under the action of gravity, collect at the intracavity of catchmenting, thereby avoid getting into empty filter this internally, guarantee the result of use of inside filter core, avoid the problem of the engine abnormal damage who takes place because of intaking, when moisture reaches certain liquid level, the drainage is opened to the check valve, can realize the drainage function, can avoid appearing the suck-back phenomenon again, high safety, moreover, the steam generator is simple in structure, and reasonable design, low in cost, the practicality is good.

The utility model is further improved in that the inclination angle of the air inlet pipe is 45-60 degrees. Guarantee effectual moisture and collect the angle, avoid moisture to get into inside the empty filter body.

The utility model discloses a further improvement still, above-mentioned distributive pipe height is higher than the intake pipe height. The moisture is collected effectually, and intake pipe and upper portion pipe connection department have the connection structure who influences the rivers direction, can avoid water when the junction, produce rivers unstability and get into the phenomenon of empty filter body.

The utility model discloses a further improvement still, above-mentioned distributive pipe upper portion edge is the shape of inwards inclining. Ensuring good moisture collection effect.

The utility model discloses a further improvement still, above-mentioned check valve is the duckbill check valve. Simple structure, low in cost can satisfy automatic drainage under certain liquid level, can avoid suck-back phenomenon again.

The utility model has the advantages that: 1. rainwater entering along with air flow can be removed, moisture can be prevented from entering the air filter body, the use effect of the internal filter element is ensured, and the problem of abnormal damage of an engine caused by water inflow is avoided; 2. the water collecting effect is good, the structure is simple, the design is reasonable, the manufacturing cost is low, and the implementation is easy.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the drawings: 1. air inlet channel, 2, distributive pipe, 3, intake pipe, 4, water collecting cavity, 5, drain pipe, 6, check valve, 7, empty filter body.

Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

As shown in the accompanying drawings, the oil bath type air filter dewatering device comprises an air filter body 7, an air inlet pipe 3 with a certain inclination angle is arranged at the upper part of the air filter body 7, a water distribution pipe 2 is arranged inside the air inlet pipe 3, an annular water collection cavity 4 with a closed bottom is formed between the water distribution pipe 2 and the air inlet pipe 3, a drain pipe 5 is arranged at the bottommost end of the water collection cavity 4, and a duckbill one-way valve 6 is arranged on the drain pipe 5.

The inclination angle of the air inlet pipe 3 is 45-60 degrees. Guarantee effectual moisture and collect the angle, avoid moisture to get into empty filter body inside, the effective collection of moisture can all be influenced to too big or the undersize of inclination.

The height of the water diversion pipe 2 is higher than that of the air inlet pipe 3. The moisture is collected effectually, and intake pipe 2 and upper portion pipe connection department have the connection structure who influences the rivers direction, can avoid water when the junction, produce rivers unstability and get into the phenomenon of empty filter body.

The upper edge of the water diversion pipe 2 is inwards inclined. Guarantee good moisture collection effect, avoid inside moisture gets into empty filter body.

This empty filter water trap of oil bath formula is when using, installation pipeline is connected on 3 upper portions of intake pipe, start empty filter body 7, when having the moisture in the pipeline of being connected with intake pipe 3, when 2 upper portion edges through distributive pipe, moisture will enter into the chamber 4 that catchments, gaseous admission passage 1 from 2 inside formation of distributive pipe enters into empty filter body 7, carry out filtering operation, can form certain negative pressure of breathing in intake pipe 3 department, when catchmenting when the intracavity 4 moisture gathers certain liquid level, dead weight pressure through moisture, make duckbill check valve open automatically, drain, behind the evacuation water, duckbill check valve is automatic closed, prevent to take place the suck-back phenomenon from duckbill check valve. And when empty filter body 7 is at the shut down in-process, engine speed reduces, and intake pipe 3 department produces the negative pressure and diminishes promptly, and when certain critical value, duckbill check valve also can open automatically, carries out the drainage, and empty filter is in the stop process state at this moment, even take place to suck backwards, also can not exert an influence to the filter effect.

This empty filter water trap of oil bath formula, simple structure, reasonable in design, low in cost easily realizes, and it is effectual to catchment, can get rid of the rainwater that gets into along with the air current, can avoid moisture to get into empty filter originally internally, guarantees inside filter core result of use, avoids the engine abnormal damage problem because of intaking and taking place.
