Description

The invention relates to devices for separating, collecting and removing oil substances from a liquid, for example oil products from coolant and water-based detergent solutions, and can be used in various industries.

Closest to the present invention is a device for separating and removing oil substances from liquids, comprising a frame, fitted with floats, vertical discs mounted on the frame, rigidly mounted on a shaft connected to a drive, a device for removing adhered oils. discs of flat scrapers arranged in the opposite direction to the movement of discs tilted to their horizontal axis and connected to the chute for draining the oil, the receiver of the separated oil mounted on the frame and the device for removing the oil from riemnika. The scrapers are angled to the plane of the disk, and each scraper is placed on a support pivotally connected to the frame of the device and equipped with an upward lever, the end of which is connected by means of a spring with a similar lever of the twin scraper. The receiver of the separated oil is made in the form of an autoclave equipped with an inlet pipe with a suction hopper and a valve evacuated with a tube for draining the collected oil. Inside the autoclave there is a tubular heating element circulating under pressure steam. The device for removing the separated oil from the autoclave is made as a source of compressed air or nitrogen associated with the internal cavity of the autoclave through the aforementioned valve. When supplying compressed gas, the valve blocks the flow of oil separated from the discs into the autoclave.

The disadvantages of the known device are the complexity of the design, due to the complexity and cumbersome installation of the scrapers, the complexity of the autoclave, the need to use a source of compressed gas, the low durability of the disk-scraper pair due to large specific loads on the surface of the scraper blades mounted obliquely, which leads to

ABOUT

about

increased resistance to rotation of the discs, and reduced safety of the device due to the use of an autoclave working under pressure and using steam to preheat the oil. The latter required the use of an anti-inflammatory device.

The aim of the invention is to simplify the contraction and increase the durability and safety of work.

The goal is achieved by the device for separating and removing oil from liquids, which contains a drive mounted on a frame with floats with a shaft on which vertical discs are fixed, flat scrapers springed to the discs and opposite to the movement of the discs tilted to the horizontal and connected to the chute for draining oil, an oil receiver with oil removal means mounted on the frame, oil removal means made in the form of a piston pump, the piston of which is kinematically connected to the shaft m, scrapers for removal of oil are placed in parallel planes and mutually connected by drives with elastic grooves for drainage of oil placed between adjacent discs,

It is advisable to fasten the pump onto the frame, and connect the pump piston to the shaft by means of a crank.

Figure 1 shows the device, front view; figure 2 is the same, top view; in fig. 3 shows section A-A in FIG. Fig 4 - section BB in Fig.Z; in fig. 5 - Hydraulic circuit of the pumping device in principle.

A device for separating and removing oil from liquids comprises a frame 1 fitted with floats 2, vertical discs 3 made of oleophilic material rigidly fixed on shaft 4, connected with drive 5, spring-loaded 6 in pairs to discs 3 flat scrapers 7 for removing oil placed between adjacent disks 3 parallel to their planes and connected in pairs with an elastic groove 8 for draining oil, a receiver 9 of separated oil placed on frame 1. and a means of removing masp from the receiver, made in the form of a piston pump 10, attached to the frame 1 pivotally. Scrapers 7 freely mounted on the shaft 4 and the fixed rod 11 and are arranged opposite to the movement of the disks 3 with an inclination to the horizontal. The pump 10 is connected by the suction pipe 12 to the receiver 9 of the separated oil and the discharge

pipe 13 with a collection of oil (not shown). Non-return valves are installed on the pipelines. A double-acting pump can be used in the device.

(one or two), as shown in FIG. 2, for a more uniform and increased pumping of fluid from the receiver 9. The piston rod 15 of the pump 10 is kinematically connected to the shaft 4 via the crank 16.

The device works as follows

During the rotation of the discs 3. partially immersed in a liquid, oily substances stick to them;

surface. Scrapers 7, in contact with the disks 3, remove from their surface an adhered film of oil, which flows from two adjacent scrapers into the chute 8, which is tilted in the same way as the scrapers. By chute

8, the oil flows into the receiver 9, and then pump 10, driven from the shaft 4, is removed outside the device into an oil collector,

The proposed device is easy to

compact design, has a lower power consumption compared to the prototype, since the rotation of the discs and pumping out the collected oil is carried out from a single engine, the device has a constant

buoyancy due to the continuous removal of oil from the collector, more durable due to the reduction of wear of rubbing pairs of discs - scrapers and safe in operation.
