Description

Lubricating oil tank

Technical Field

The utility model relates to an oil tank for mechanical equipment lubricating system.

Background

A large number of rotating parts exist in mechanical equipment, and lubricating oil is generally adopted for lubricating rotating parts in use. Mechanical equipment rotating at a high speed needs to lubricate a rotating part, and needs to take away surface heat through lubricating oil to cool down, so a special lubricating system is generally arranged, the lubricating oil in a lubricating oil tank is pumped to the part needing lubrication and heat dissipation through an oil pump and then flows back into an oil tank, in the process, impurities such as iron powder and the like generated at the rotating part can be mixed in the lubricating oil, and in order to improve the cleanliness of the lubricating oil and prevent damage to rotating parts, the lubricating oil flowing back into the lubricating oil tank needs to be filtered and cleaned.

The oil return filter assembly of chinese patent publication No. CN209254976U, which was previously applied by the present applicant, can filter the lubricating oil or other grease flowing back into the oil tank, mainly to eliminate the iron powder and iron filings carried therein. In practical use, however, the grease also contains some non-ferromagnetic impurities which are difficult to adsorb by the magnet, and the impurities are precipitated to form oil sludge after entering the lubricating oil tank. The oil sludge in the lubricating oil tank is very harmful to the whole lubricating system, so other impurities in the lubricating oil need to be fully filtered and removed, and the oil sludge in the lubricating oil tank is eliminated; meanwhile, sludge precipitated in the lubricating oil tank needs to be cleaned in time, and the sludge is prevented from being mixed into a lubricating system again and causing damage to the safe operation of equipment.

At present, the oil adding and filtering device of an oiling machine oil tank adopts a labyrinth sealing mode as a Chinese patent publication No. CN204018009U to carry out sufficient precipitation and filtration, but the oil sludge accumulated in the filter is difficult to clean. The oil tank return oil magnet filtering device disclosed in the Chinese patent publication No. CN205744706U also adopts a magnetic suction mode to adsorb ferromagnetic impurities; the oil filter tank for filtering hydraulic oil disclosed in chinese patent publication No. CN103321989A is only suitable for large-scale oil storage devices, and needs to be replaced and filtered with enough oil.

Certainly, special filter bags and filter elements are also arranged on the market, so that the lubricating oil can be efficiently filtered, but the filter bags and the filter elements are generally made of plastic products such as non-woven fabrics and the like, are disposable, and need to be replaced frequently, so that the materials are consumed.

Therefore, it is necessary to further study the filtering system of the lubricating oil tank in order to meet the requirement of a high-precision lubricating system.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lubricating-oil tank to it is not thorough to solve lubricating oil filtration, and the difficult problem of clearance of oil sludge sediment in the lubricating-oil tank.

In order to achieve the purpose of the utility model, the utility model provides a lubricating oil tank, which comprises an oil tank body, wherein a dustproof cover is covered on the oil tank body, and an oil outlet and an oil return port are arranged on the dustproof cover;

the device is characterized in that a ferromagnetic filter screen component is sleeved on the oil return port;

a filter barrel is arranged below the oil return port; the filter barrel comprises a barrel body and a filter screen;

the barrel body is provided with a closed barrel bottom for receiving oil sludge; the wall surface of the barrel body is provided with a plurality of oil passing grooves; and a filter screen is detachably fixed on the outer side of the barrel body.

As a further improvement, the filter screen is fixed on the barrel body through the hoop.

Furthermore, more than 2 clamps are arranged on each set of filter barrel; one hoop is fixed on the upper part of the barrel body; one of the clamps is fixed at the lower part of the barrel body.

Furthermore, the filter screen is a stainless steel filter screen with more than 500 meshes.

Furthermore, the oil passing groove is strip-shaped and horizontally distributed on the outer side wall surface of the barrel body in a staggered manner.

As a further improvement of the utility model, a filter vat is also arranged below the oil-out.

The lubricating oil tank of the utility model is additionally provided with the filter barrel below the oil return port, the return oil firstly enters the filter barrel through the oil return port, and the oil passing groove forms an irregular oil path to reduce the flowing speed of the oil; meanwhile, the impurities in the oil are precipitated and fall into the filter vat by the blocking of the filter screen, so that the content of the impurities in the oil product flowing out of the filter vat is reduced. The filter barrel is convenient to take out from the oil tank and clean; and can be recycled after cleaning, thereby avoiding material consumption.

The utility model discloses a lubricating-oil tank compares with prior art, has following advantage:

(1) the filter vat has large size, and the oil path can not be blocked when the filter screen with high mesh number is adopted, so the filter effect is good;

(2) the filter barrel can be conveniently taken out, and the maintenance is more convenient;

(3) the existing lubricating oil tank can be conveniently transformed and upgraded.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the lubricating oil tank of the present invention has a shape consistent with that of a conventional oil tank, and is provided with a sealed oil tank body 11, a dust cap 12 is covered on the oil tank body, an oil pump 13 is installed on the dust cap 12, and a removable access opening 14 is also started on the dust cap 12; an oil outlet 15 and an oil return port 16 are formed in the dustproof cover 12; the oil return port 16 is sleeved with an oil return filter component such as a chinese patent publication No. CN209254976U, or an oil tank oil return magnet filter device such as a chinese patent publication No. CN205744706U, and a ferromagnetic filter screen component is adopted to perform primary filtration on the return oil.

As shown in fig. 2, the utility model discloses lubricating-oil tank's improvement lies in the below of oil return opening 16 is equipped with filter vat 2, deposits the filtration to the oil return, and makes the fatlute after filtering deposit in filter vat 2, during the clearance, directly take out filter vat 2 can, removed from and opened whole shield 12 to manage to find time the fuel tank body 11, just can clear up the fatlute of bottom.
