Abstract

The utility model relates to a device for cleaning oil tank pneumatic energy, which is characterized in that the device comprises multi-channel of annular pipelines (4) which are fixedly arranged on the bottom portion of an oil tank through an overhead mode, the multi-channel of annular pipelines are respectively communicated with gas transmission pipelines (6) through communication pipe fittings, and a plurality of nozzles (5) whose spouts toward the bottom of the tank are arranged around the bottoms of the annular pipelines. The device for cleaning oil tank pneumatic energy not only can save the man power and material resources of cleaning the bottom portion of the oil tank, greatly increases the cleaning work efficiency, can reduce the oxygen concentration in the tank through the mode of injecting inert gas to the tank from a lower nozzle, achieves the controlled atmosphere reserve of low oxygen or oxygen lack, reduces the oil oxidation, and guarantees the safety of oil storage.

Description

A kind of device that is used for the cleaning of oil tank strength

Technical field

The utility model relates to the cleaning technology of oil tank, especially relates to a kind of device that adopts the strength mode to clean the tank bottom greasy dirt that is applicable to.

Background technology

Vegetable fat generally contains a large amount of unsaturated fatty acids, is easy to oxidative breakdown in storage, and free fatty acid content constantly increases, and acid value raises, and the change of becoming sour gradually is bitter.Especially under the aerial oxygen effect, the fat that contains a large amount of unsaturated fatty acids locates to form peroxide at " two key ", peroxide continues to decompose again, then can generate aldehydes or letones, makes color with oil color deepen, diaphaneity diminishes, accretion increases, and becomes sour at last, produces to have bitter peppery smell---the rancidity of volatility, make the quality of vegetable oil descend or bad change the serious commodity value lost.Owing to grease contains impurity such as colloid, the accretion of oxidative rancidity formation can under static state constantly precipitate in addition, after long storage, can accumulation extruding formation influence the follow-up use of oil tank than the difficult grease of clearing up at the bottom of jar.Therefore, remove aborning and take heat-insulation and heat-preservation, lucifuge, apply antioxidant laying in oil, technical measures such as controlled atmosphere, prevent grease outside the oxidative rancidity of storage process, also adopt the agitating function of circulation pump to reduce contamination precipitation in the grease, perhaps after oil tank has been put oil, manually advance jar and clear away.But above-mentioned way exists expense height, wasting manpower and material resources, efficient is lower, effect is undesirable, and enterprise demands seeking a kind of short-cut method urgently, solves oil foot and clears away problem.

Summary of the invention

The purpose of this utility model provides a kind of device that is used for the cleaning of oil tank strength just at existing weak point in the above-mentioned prior art.This device is not only easy and simple to handle, expense is low, also can save manpower, improve work efficiency, has solved a large amount of deposition oil foot and the grease cleaning problems in large oil tank bottom preferably.

The purpose of this utility model can realize by following technique measures:

The device that is used for the cleaning of oil tank strength of the present utility model comprises the multiple tracks looped pipeline that is fixedly mounted on tank bottom by support in built on stilts mode, described multiple tracks looped pipeline is connected with gas line by connecting pipe respectively, is provided with the nozzle of several spouts at the bottom of jar around the bottom surface of described looped pipeline.

Tank bottom of the present utility model centre is provided with sewage draining exit, and whole tank bottom is by periphery to the domatic structure of center sewage draining exit bevelled.

Principle of work of the present utility model and beneficial effect are as follows:

1, after the grease in the oil tank has been banished, can spray gas by the following nozzle that tank base is installed on the circulating line, under the gas momentum effect, the precipitation of grease thing and the impurity that are attached to tank bottom are blown afloat, greasy dirt along jar underflow that tilts to sewage draining passage, last greasy dirt is discharged from sewage draining exit, not only can save the man power and material of tank bottom cleaning, and also can improve the cleaning work efficiency widely.

2, during the grease normal storage, by descending the jet of nozzle, can in grease, play beating action, prevent the decline of precipitation of grease thing between the storage life, reduce the greasy dirt and the cleaning works amount of adhering on the ground.

3, during the grease normal storage, also can in jar, spray into unreactable gas by following nozzle---as nitrogen etc., the oxygen concentration in reducing jar realizes the controlled atmosphere deposit of hypoxemia or anoxic reducing Oxidation of Fat and Oils, guarantees oil storage safety.

The specific embodiment

The utility model is done below with reference to embodiment (accompanying drawing) and is described in further detail:

As shown in Figure 1, the device that is used for the cleaning of oil tank strength of the present utility model comprises the multiple tracks looped pipeline 4 that is fixedly mounted on tank bottom by support 3 in built on stilts mode, described multiple tracks looped pipeline is connected with gas line 6 by connecting pipe respectively, and gas line 6 is connected with a jar external compression source of the gas by pipeline; Bottom surface around described looped pipeline is provided with the nozzle 5 of several spouts at the bottom of jar; Described tank bottom centre is provided with sewage draining exit 1, and whole tank bottom 2 is by periphery to the domatic structure of center sewage draining exit bevelled---be promptly that periphery is high, the structure of central fovea.

Claims

1. one kind is used for the device that the oil tank strength is cleaned, it is characterized in that: described device comprises the multiple tracks looped pipeline (4) that is fixedly mounted on tank bottom by support (3) in built on stilts mode, described multiple tracks looped pipeline is connected with gas line (6) by connecting pipe respectively, is provided with the nozzle (5) of several spouts at the bottom of jar around the bottom surface of described looped pipeline.

2. the device that is used for the cleaning of oil tank strength according to claim 1, it is characterized in that: described tank bottom (2) centre is provided with sewage draining exit (1), and whole tank bottom (2) is by periphery to the domatic structure of center sewage draining exit bevelled.
