Background

The applicant considers that the separation effect of the improved negative pressure gas-driven active separator based on the similar principle of a venturi jet pump and the like is poor because the engine has relative large-load and small-load working conditions relative to the pressure separator, the separation effect of the pressure separator is improved along with the increase of the working load, but the opening degree of the pressure separator is increased and the separation effect is poor for the small-load working condition; when the pressure generated by the working load floats at the lower limit pressure of the pressure separator, the separation effect is poor.

For non-variable separators where the separation structure is not movable, the flow resistance generally increases in a squared relationship with increasing flow, resulting in less efficient separation or greater pressure loss.

In addition, the traditional cylinder cover cap only integrates a simple passive separation structure, has a simple structure and low separation efficiency, and cannot better meet the increasing requirements of engine emission regulations and higher separation efficiency.

Detailed Description

The present application is described in further detail below with reference to figures 1-5.

In the utility model discloses improve the in-process of separator, utility model active oil-gas separation is as the external oil-gas separator of stand alone type usually, not only has with high costs, needs great assembly space scheduling problem in the engine compartment, especially under the condition of no heat source input, also has the risk of freezing easily under winter low temperature environment. When the engine is in a low-load working condition, the pressure self-adaptive valve port of the negative pressure separator based on the similar principle of a Venturi jet pump and the like is fully opened or is opened to a large degree, and the efficiency of the separator is lower (compared with a medium-high load working condition).

Referring to fig. 1, a pressure-flow two-stage adaptive oil-gas separation module, where the upper portion may be a common pressure adjustment module, and the lower portion is a flow adjustment module, preferably a flow adaptive module, which preferably includes a channel portion 2 for passing through a gas flow to be separated, and a flow adjustment separation module 77 may be installed at any position of the channel portion 2, and for convenience of description, is defined as a flow separation channel 78, and the flow separation channel 78 includes a flow adjustment inlet portion 79, a flow adjustment gap portion 80, and a flow adjustment outlet portion 81, which are sequentially arranged, and the opening degree of the flow adjustment separation module 77 in the flow separation channel 78 is variable. However, there is a problem in that the gas flow to be separated is output after passing through the gap between the inner wall of the flow rate adjusting gap portion 80 and the outer wall of the flow rate adjusting and separating module 77, thereby causing an ineffective loss of energy and reducing the separation effect.

As shown in fig. 2, the flow rate adjustment separation module 77 may implement automatic reset to adjust the flow rate adjustment gap 80 according to the modification of fig. 1. The flow regulating separation module 77 includes a flow regulating part 83, and the automatic reset means that the flow regulating part 83 has a flow valve reset part 84 and/or resets through its own elasticity, it should be noted that the reset force is small, and only the adjustment gap part 80 needs to be adjusted, and as the impulse of the air flow to be separated and/or the pressure in the inner cavity of the flow regulating inlet part 79 increases, the opening degree of the flow regulating part 83 increases. When the work is carried out under a small load, the flow regulating gap part 80 becomes small, so that the speed is increased, and a better impact effect is realized.

In order to reduce the ineffective loss of the air flow energy at the flow regulating gap portion 80, an oblique transition, an arc transition or other smooth transition is preferred, and in addition, the oblique transition, the arc transition or other smooth transition can better enable the separated liquid to flow out quickly, so that the freezing in the low temperature condition in winter is avoided. To avoid the inefficient dissipation of energy at a in fig. 1, a flow regulating outlet 81 is provided on the side wall of the flow separation channel 78; in order to enhance the impact effect, the impact separation part 82 of the flow rate is arranged opposite to the outlet of the flow rate regulation outlet part 81, and in the specific design, the impact separation part 82 is arranged opposite to the outlet of the flow rate regulation outlet part 81 by using the internal components of the main body part 1 as the impact separation part 82 (for example, the inner wall of the separation output channel 91 after impact of the channel part 2), so that the good impact is realized. The outlet of the post-impact separation output channel 91 continuously outputs the airflow after flow separation.

Wherein, the separation output channel 91 after the impact is provided with a deepened separation cavity 90 positioned at one side of the impact separation part 82, so that the space of the separation output channel 91 after the impact is increased, the speed difference between the air flow and the solid and/or liquid to be separated can be better realized, and the better separation can be realized. Due to the fact that the separation cavity 90 is deepened, part of impacted airflow flows in the cavity, better separation is achieved, and the separation cavity is better in process structure, and local over-thick solid wall thickness is avoided.

As shown in fig. 3-4, fig. 4 shows a partial structure of 1/4 as a product structure, according to which a complete structure can be obtained, the separating part includes a main body part 1, a channel part 2 is arranged in the main body part 1 for circulating the gas flow to be separated, the source of the gas flow to be separated can be a gasoline engine, a diesel engine or other similar new energy engine, a power machine, and the separated gas flow can be directly discharged, recovered or recycled.

The flow regulating portion 83 includes a flow regulating cap 88 variable in position at the flow regulating inlet portion 79, and a variable opening flow regulating gap portion 80 is provided at a lower portion of the flow regulating cap 88 to regulate an outer skirt portion 89 of the gap opening, which preferably transitions smoothly.

The flow regulating cap 88 is preferably hollow to reduce weight and improve process construction.

1. As shown in fig. 3 to 4, a lower support portion 85 having a guide through hole portion 86 is provided in the main body portion 1 to support the flow rate regulating portion 83. A flow valve returning part 84 is provided between the lower support part 85 and the flow rate adjusting cap 88, and may be a spring, a magnetic force, rubber, or the like, or may be a single or combined action of other elastic force, field force, electromagnetic force, or air pressure.

The lower outlet of the post-impact separation output passage 91 may be provided on the flow valve resetting section 84,

a guide rod portion 87 is connected to a lower portion of the flow rate adjusting cap 88, inserted into the guide through hole portion 86,

a return passage 92 located below the lower support portion 85 is provided in the main body portion 1, and the return passage 92 communicates with a lower outlet of the post-impact separation delivery passage 91.

The pressure separation module 76 and the flow regulation separation module 77 can be arranged in the channel part 2 according to the design, the sequence of the two modules can be front or back, the number is not limited, and other components can be arranged in the middle; the flow regulating separation module 77 may also be connected in parallel or in series with a fixed configuration of non-variable separation. Fig. 3-4, are merely one of the preferred embodiments to achieve better pressure control and separation efficiency for both heavy and light load conditions.

As shown in fig. 5, the separating mechanism of the embodiment can be integrated into the cylinder cover cap, and the main body portion 1 is the cylinder cover cap, so that the oil-gas separation efficiency and the pressure control of the engine are greatly improved, the requirements of the ever-increasing engine emission regulations are met, the cost of the oil-gas separation system of the engine is greatly reduced, and more space of an engine cabin is not required to be occupied. Because the separating mechanism is integrated in the cylinder cover, the risk that the external independent separator is possibly frozen in the low-temperature environment in winter is well solved.

Preferably the flow adaptation is located upstream (depending on the direction of flow of the gas stream) of the pressure adaptation, and may also be located downstream but is not preferred; the flow regulating separation module 77 may also be connected in parallel or in series with a fixed configuration of non-variable separation.

The preferable implementation principle of the negative pressure gas-driven separator based on the similar principle of the Venturi jet pump and the like is as follows: when the user uses, when parts such as engine, etc. work, the air current that waits to separate from getting into passageway portion 2, when heavy load work (optional operating mode), pressure separation module 76 opening degree diminishes, waits to separate the air current and gets into the impact body in the pressure separation module, then descends, acts on flow control cap 88 for it overcomes flow valve reset 84's reset force and opens or the aperture grow. When the workload is small, the opening degree of the pressure separation module 76 is increased or larger, the air flow acceleration effect is poor, and at this time, the corresponding opening degree of the flow rate adjustment gap part 80 is small, so that the air flow is accelerated rapidly, and then directly collides with the collision separation part 82, and the air flow is output through the separation output channel 91 and the return channel 92 after collision.

As an expanded application, the pressure-flow two-stage adaptive oil-gas separation module and/or the flow adaptive module may be applied to a separator externally arranged as in fig. 3-4 or fig. 5, or a cylinder cover integrated with a separation function, or other engine components integrated with a separation function, further, the separator may be applied to an engine or the like assembly or a power assembly, and the assembly may also be applied to a system such as an engineering machine, an automobile, a ship, a generator, an agricultural machine, a power machine, and the like.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
