Abstract

Usage: the invention relates to the storage of liquids and can be used, for example, in the oil and chemical industries. SUMMARY OF THE INVENTION: The floating intake is provided with a conical tray package, and the suction pipe is equipped with flexible inserts, 2 sludge.

Description

The invention relates to the field of liquid storage and can be used, for example, in the petroleum and chemical industries.

The purpose of the invention is to increase operational reliability while reducing the contamination of the effluent.

The goal is achieved by the fact that the floating intake is equipped with a conical plate package placed under the float on the washers, the suction pipe section in front of the intake and the hinge assembly are made in the form of an insert made of flexible material.

Figure 1 shows a longitudinal section of a tank with a floating intake in the working position; figure 2 - floating ababor in the context.

The fluid reservoir (Fig. 1) comprises a housing 1, a floating intake 2 having a float assembly, inserts 3 of flexible material in the form of sleeves, a suction pipe 4, a height limiter 5, a counterweight with blocks 7 and a cable 8.

. The floating intake (Fig. 2) contains a packet of conical plates 9, a float 10, an elbow 11, a clamp sleeve 12, a ring 13, and support posts 14.

The housing 1 serves to store liquid with its periodic filling into the reservoir and dispensing from the reservoir. Simultaneously with the storage of liquid, its gravitational purification occurs due to sedimentation of particles of pollution. The floating intake 2 serves to collect liquid from the upper, purest layers thereof when discharged from the reservoir. The suction pipe 4 and inserts 3 made of flexible material are used to dispense fluid from the tank while moving the floating intake 2 in the horizontal direction without the use of articulated joints. The height limiter 5 serves to limit the movement of the connecting pipe 4 and prevents damage to the inserts 3. The counterweight 6 is connected to the floating intake 2 by a cable 8 and blocks 7 and serves to prevent the floating intake 2 from deviating from horizontalCO

direction, and at the same time partially destroys the float 10, thereby reducing its size. The conical tray package 9 serves to further purify the liquid when it is discharged from the reservoir. The float 10 serves to raise the floating intake 2 into the upper layers of the liquid. The bottom of the float 10 is conical and is the upper generatrix of the package of conical plates 9. The square 11 is attached to the lower conical plate of the package 9 and serves to connect the suction communication, consisting of sleeves 3 and the connecting pipe 4 with the internal cavity, the package of conical plates 9 The ring 13, the support posts 14 and the clamp 12 serve to secure the parts of the floating intake. The fluid reservoir operates as follows. When liquid is poured into the tank body T, the floating intake 2 from the lower position (dashed in Fig. 1) rises together with the inserts 3 and the connecting pipe 4 under the influence of the lifting force of the float. 10 and reaches the upper position determined by the height limiter 5. In this case, the total lifting force of the float 10 and the counterweight .6 is selected in such a way: so that the package of conical t% rods is completely immersed in the upper layers of the liquid. During storage of the liquid, large contaminants contained therein are lowered by gravity to the bottom of the tank. When liquid is dispensed from the reservoir by the co0 transfer pump

a vacuum is created in the floating intake 2, the liquid enters the inter-tray space of the packet 9, in which the process of dynamic sedimentation of contaminants, settled on the tank, takes place. In this case, solid particles of contaminants and water droplets under the influence of gravity settle on the plates and roll back onto the conical surface on the conical surface, and the liquid flows through the elbow 11, inserts 3 of flexible material and the suction pipe 4.

As the liquid level decreases in the tank, the floating intake 2 lowers to a lower position, which is determined by the size of the support posts 14. This size is chosen so that no liquid flows from the lower, most contaminated layers.
