Description

Oil tank respirator

Technical Field

The utility model relates to an oil tank accessory technical field especially relates to an oil tank respirator.

Background

Screw does not have oily blower is a novel compression technology's air compressor machine, and is different with roots's fan etc. and screw fan has realized the internal compression at the in-process of gas transport in the cavity, therefore the screw rod possess more than roots and possess higher efficiency outside the advantage of roots most, and the process of gas transport compression is progressive in succession, and the air current pulsation is lower, and exhaust noise, temperature control etc. all will be superior to traditional fans such as roots.

As a rotary blower type which is newly developed in recent years, a screw fan has the advantages of simple structure, stability, energy conservation, low noise and the like, is commonly applied to aeration, air-water back flushing, oxidation desulfurization, fluidization/homogenization process, pneumatic conveying and the like, can be a product for replacing a Roots fan, and is widely used in various industries.

The prior art has the defects that: because the screw blower is different from a conventional screw compressor, lubricating oil is injected into a compression cavity of the conventional screw compressor as a medium to play roles of lubrication, temperature reduction, noise reduction and the like, the lubricating oil forms a closed loop in the whole system, oil is supplied to bearings and gears of the screw blower through an oil pump, the lubricating oil flows back into an oil tank at the bottom through gravity after entering a gear box, the air is free of oil participation in the blower to realize that compressed gas is free of oil, so that the lubricating oil for the gears and shaft seals is blown to the gear box through gas in the compressor through an inter-shaft gap on a shaft, and the part of gas returns to the oil tank along with the lubricating oil, because the oil temperature is high and the oil mist is evaporated, the gas is accumulated in the oil tank and overflows from a ventilation port of the oil tank, and after a long time, the equipment is covered by the oil mist, the machine, the existing oil tank ventilation cap available in the market has the advantages of simple structure, coarse filtration, incapability of effectively separating oil mist in gas and achieving the functions of breathing, oil separation and oil separation recovery, and is necessary to improve the existing technology and design an oil tank respirator based on the defects and shortcomings.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides an oil tank respirator, simple structure can filter oil-gas mixture, the internal and external pressure of balanced oil tank, and oil-gas mixture can not run off through filtering, can prevent that the foreign matter from falling into in the air cleaner.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides an oil tank respirator, this kind of oil tank respirator include air cleaner, rubber pad, baffle and automatic sealing subassembly, and air cleaner installs on the oil tank, and the cover is equipped with the rubber pad on the air cleaner, install the baffle on the flange board on air cleaner upper portion, the filter paper is equipped with in the air cleaner, the filter paper annular forms the filter bed along the setting of air cleaner inner wall, and the air cleaner bottom is provided with the oil gallery, and the air cleaner bottom is installed with oil gallery complex automatic sealing subassembly.

Preferably, the automatic sealing assembly comprises a turnover support, a turnover plate, a pin shaft, a silica gel plug and a counterweight bolt, the turnover support is fixed at the bottom of the air filter, the turnover plate is movably inserted on the turnover support through the pin shaft, the silica gel plug is arranged on the turnover plate below the oil return hole, and the counterweight bolt is arranged at the other extending end of the turnover plate.

Preferably, the air outlet grids are arranged on the partition board in an array mode.

Compared with the prior art, the beneficial effects of the utility model are that:

the structure is simple, the oil-gas mixture can be filtered, and the internal and external pressures of the oil tank are balanced;

during filtering, the oil return hole is closed, and the oil-gas mixture cannot be lost without being filtered;

the arrangement of the clapboard prevents foreign matters from falling into the air filter.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make clear and definite definitions of the protection scope of the present invention.

Referring to fig. 1 to 3, an embodiment of the present invention includes:

the utility model provides an oil tank respirator, this kind of oil tank respirator includes air cleaner 1, rubber pad 2, baffle 3 and automatic sealing subassembly 4, and air cleaner 1 is installed on the oil tank, and the cover is equipped with rubber pad 2 on the air cleaner 1, install baffle 2 on the flange board on air cleaner 1 upper portion, filter paper is equipped with in the air cleaner 1, the filter paper annular sets up along 1 inner walls of air cleaner and forms

filter material layer

10, and 1 bottom of air cleaner is provided with oil gallery 11, and air cleaner 1 bottom is installed with oil gallery 11 complex automatic sealing subassembly 4.

The automatic sealing assembly 4 comprises a turnover support 41, a turnover plate 42, a pin shaft 43, a silica gel plug 44 and a balance weight bolt 45, wherein the turnover support 41 is fixed at the bottom of the air filter 1, the turnover plate 42 is movably inserted into the turnover support 41 through the pin shaft 43, the silica gel plug 44 is mounted on the turnover plate 42 below the oil return hole 11, and the balance weight bolt 45 is mounted at the other extending end of the turnover plate 42.

An air outlet grid 30 is arranged on the partition board 3 in an array manner.

The utility model relates to an oil tank respirator during operation, the gas-oil mixture gets into inside through air cleaner 1 side in the oil tank, air cleaner 1 filters gaseous state oil's filter paper winding and forms very thick filter bed 10, filter and condense gaseous state oil into liquid oil, the liquid oil of air cleaner 1 surface falls under gravity and flows back to the oil tank, the liquid oil of air cleaner 1 surface gathers inside air cleaner 1, when the oil mass is little, the quality of counter weight bolt 45 on returning face plate 42 is great than the quality of oil, counter weight bolt 45 moves down and drives the silica gel end cap 44 of returning face plate 42 other end to move up and seal oil return hole 11, after the oil mass increases in air cleaner 1, be greater than counter weight bolt 45 quality after, returning face plate 42 is opened, liquid oil flows back to the oil tank, so move repeatedly, reach the oil-gas mixture, the gas in the oil tank soaks the balanced internal and external pressure, lubricating oil in the main engine gear box can flow back to the oil tank through gravity, and the top clapboard 3 prevents foreign matters from falling into the air filter 1.

The utility model relates to an oil tank respirator, simple structure can filter oil-gas mixture, the internal and external pressure of balanced oil tank, and oil-gas mixture can not run off through filtering, can prevent that the foreign matter from falling into in the air cleaner.
