Description

Crude Oil Filter Bed Manifold Controls

technical field

The utility model relates to the field of oil pressing devices, in particular to a manifold control device for crude oil filter beds.

Background technique

Crude oil refers to primary oil obtained from animal or vegetable oils without refining. Due to the simple processing technology of crude oil, this kind of oil contains many impurities and is easy to oxidize and deteriorate, so it is not suitable for long-term storage. Crude vegetable oil produced by oil extraction may be mixed with particulate impurities such as raw material shells, so sedimentation and filtration are required. The precipitated crude oil still cannot be used directly, and needs to be treated by coarse filtration and fine filtration to remove impurities more comprehensively.

In terms of effect, coarse filtration and fine filtration are mainly due to the difference in filtration precision. If the coarse filtration precision is low, the efficiency of the fine filtration stage will be low, and at the same time the consumption of filter screen and filter paper will be large; if the coarse filtration precision is high, although It can reduce the consumption of consumables during fine filtration, but if there are too few impurities in the oil, it is difficult for the impurities to form a barrier layer on the surface of the filter screen. Since the barrier layer can strengthen the filter effect of the filter screen, the fine filter effect of the oil is not good. Therefore, It is difficult to find a balance between coarse filtration and fine filtration.

Utility model content

The utility model provides a manifold control device for a crude oil filter bed, which can simultaneously improve the effects of coarse filtration and fine filtration.

The technical scheme that the utility model adopts is:

A crude oil filter bed manifold control device, comprising a crude oil filter bed, a metering device, a coarse filter device and a fine filter device, the crude oil filter bed, the metering device, the coarse filter device and the fine filter device are connected in sequence, the The metering device is connected to the fine filter device through a manifold. The manifold can control the oil that has not been coarsely filtered to directly enter the fine filter device. First, a barrier layer is formed on the filter screen of the fine filter device, and then the oil is filtered through the coarse filter device and the fine filter device in turn, so even if the oil is increased Coarse filtration accuracy will not have adverse effects on fine filtration.

Preferably, the crude oil filter bed includes a sedimentation tank, a sprocket, a chain, a scraper, a filter screen and a discharge tank, the chain is connected to the sedimentation tank through a sprocket, a scraper is set on the chain, and the filter screen and the discharge The groove is set in the sedimentation tank, and the scraper is provided with a lower curved part and an oil discharge hole, the lower curved part is arranged on one side of the scraper, which is in the shape of a broken line or an arc, and the oil discharge hole is a plurality of through holes. The lower curved part of the scraper can squeeze the impurities retained on the surface of the filter when it runs to the filter, so as to discharge the oil absorbed in the impurities and recycle it to the sedimentation tank. When the impurities at the bottom of the pool are blown up, the oil is discharged. On the one hand, it reduces the amount of oil remaining in the impurities. On the other hand, it can prevent the impurities from overflowing with the oil and affect the effect of scraping.

Preferably, the scraper is provided with an upper curved portion on the other side of the lower curved portion, and the bending direction of the upper curved portion is opposite to that of the lower curved portion. Setting the upper curved part can better scrape up the deposited impurities at the bottom of the sedimentation tank.

Preferably, an auger is arranged in the discharge trough, and the auger can improve the discharge efficiency of impurities.

Preferably, the filter screen is in close contact with the discharge tank, and the height of the filter screen is the same as that of the top of the discharge tank, or the height of the top of the discharge tank is between the top and the bottom of the filter screen. The close contact between the filter screen and the discharge tank can promote the impurities to directly enter the discharge tank instead of falling into the sedimentation tank.

Preferably, baffles are arranged on both sides of the filter screen. The baffle prevents impurities from being pushed out of the screen and back into the sedimentation tank during the movement of the scraper.

Preferably, the metering device includes a temporary storage tank and a weighing device. The purpose of not using a flowmeter here is that the mixed gas in the oil will affect the counting of the flowmeter. The oil enters the temporary storage tank for temporary storage and output, and the flow of the oil is detected by measuring the change in the weight of the temporary storage tank.

The beneficial effects of the utility model are:

1. The filtration accuracy of coarse filtration and fine filtration can be improved at the same time, and the improvement of coarse filtration can reduce the use of consumables in the fine filtration stage, while the final effect of fine filtration will not be affected;

2. On the basis of realizing crude oil precipitation and filtration, the recovery of oil from impurities is improved, excessive oil is prevented from being discarded with impurities, and the filtering effect is improved.
