Description

Novel exhaust structure for filter

Technical Field

The utility model relates to the technical field of filters, in particular to a novel exhaust structure for a filter.

Background

In the filter trade, the electric pump mainly applies to diesel filter, and the electric pump effect is: a. when the filter element is replaced, air in the diesel filter is automatically discharged, so that the phenomenon that fuel oil is mixed with a large amount of air to influence the oil supply quantity of an engine and cause insufficient power of the engine is avoided; b. in the low pressure fuel oil pipeline of engine, negative pressure is mostly, easily appear air in the diesel oil under the negative pressure condition, and the air can gather the dead angle in the pipeline, and after the engine stops, the air can slowly gather in the eminence, and the electric pump can be when the engine just starts the auxiliary pump oil, makes the engine start more easily. The problem that the filtering area is not fully utilized due to long-term air accumulation in the filter. Because diesel filter is a great cavity in the low pressure fuel pipeline, the air that the low pressure fuel pipeline produced can gather in diesel filter, and the air gathering causes filter core part area in the filter to be occupied by the air, and only partial area has oil to pass through, and filter core filter area can not make full use of. The electric pump arranged on the diesel filter can discharge gas in the diesel filter.

At present, a controller on a diesel filter is simple, is usually automatically switched off after being powered on for a few minutes, and is switched on again for a few minutes after being powered off. The working time set by different manufacturers is different, but the control strategy is the same. This control strategy is foolproof and does not allow for the timely venting of air accumulated in the filter.

In view of the above problems, a new exhaust structure for a filter is now devised.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1-3, in the embodiment of the present invention, a novel exhaust structure for a filter includes an electric pump 4 disposed in the filter 1, a filter element 2 is disposed in the filter 1, the filter element 2 divides the interior of the filter 1 into a pre-filter cavity 11 and a post-filter cavity 12, a controller 5 electrically connected to the electric pump 4 is disposed in the filter 1, the controller 5 controls the electric pump 4 to operate intermittently, the electric pump 4 and the controller 5 are integrally connected or separately disposed, an exhaust pipe 3 communicated with an oil inlet end of the electric pump 4 is disposed in the post-filter cavity 12, an upper end of the exhaust pipe 3 is communicated with an upper end of the pre-filter cavity 11, an exhaust hole 21 is disposed in the filter element 2, and an oil outlet end 13 communicated with the electric pump 4 is disposed in the filter 1, so that when the filter element 2 is wetted by oil and difficult to ventilate, gas in the pre-filter cavity 11 enters the post-filter cavity 12 through the exhaust hole 21, then start electric pump 4, make electric pump 4 with gaseous back chamber 12 suction blast pipe 3 internal and through going out oil end 13 and outwards discharge in through filtering, accessible controller 5 makes electric pump 4 interval work simultaneously to make the device realize regularly self-bleeding, just so can avoid a large amount of gas gathering in the inside of filter 1, guaranteed that the diesel oil liquid level at filter core 2 place is enough high, thereby guaranteed the filter effect of filter core 2, made things convenient for the use.

Example 2
