Description

The invention relates to the oil refining, petrochemical industry, as well as to other sectors of the economy, where there is a need for periodic cleaning of artificial or natural water bodies from bottom sludge, which is in a free-dispersed or viscous-flowing state, from settling ponds that require periodic removal of bottom sludge without interruption of operation ponds.

Known lake installation for the development of silty soils, including mounted on a floating base in the form of an open shaft with a free level of sludge with a sludge collector at the lower end, a device for moving the installation through a pond, a mechanism for loading sludge into transport tanks, in particular, a submersible monoblock electric pump, and an alarm with a float [RF Patent No. 1797640, E 02 F 3/88, Bull. No. 7, 1993].

A disadvantage of the known device is the need to control the level of sludge in the mine to ensure the operability of a submersible monoblock electric pump, a large metal structure.

Also known dredging projectile, including a floating hull, articulated from two pontoons, mounted on one of them a soil pump with suction and pressure nozzles and a hydraulic wash pump, a suction pipe with a tip, a pressure stroke apparatus and a working movement mechanism with a drive [RF Patent 2013497, E 02 F 3/88, Bull. No. 10, 1994].

A disadvantage of the known device is the strong agitation of sludge when using a pressure head apparatus, the need to use two pumps, the need to use two movement systems, and the high metal consumption of the structure.

Closest to the claimed is a device for the collection and transportation of bottom sludge, including a floating body, to the frame of which is attached a system for adjusting the depth of immersion with a flexible coupling and a submersible soil pump, a flexible pressure hose connected to the tank, a working movement mechanism installed on the shore, connected with floating housing using an annular cable and contains a reversible motor with gearbox and limit switches mounted at the points of attachment of the annular torso to the floating body su and guide rollers mounted on racks, one of which is designed to drive the annular cable, and the other is designed to move the annular cable and placed on the opposite bank, in addition, the working movement mechanism has foundation plates with anchor bolts for its fastenings located along the silt pond on the opposite bank of the settling pond, in addition, the working movement mechanism has foundation plates with anchor bolts for its fastening, located along the silt ore-ore at regular intervals, at which it is successively installed as the bottom of the sump is cleaned, and additionally foundation plates, on which racks with tension rollers are installed to loosen and tension the cable (ring cable tension rollers) when rearranging the working displacement mechanism [RF Patent No. 2183705, E 02 F 3/88, publ. Bull. No. 17, 2002].

The disadvantage of this device is a violation of the smooth movement, in which there is a stirring up of sludge, which leads to a violation of its extraction, the frequency of movement, the need to stop, labor is not automated, which requires 2-4 people to move the device to the next base plate and 1-2 hours to carry out the process of time, the complexity of the process.

The objective of the invention is the automation of the movement of the device and ensuring the continuity of its work.

The technical result is the automation of the device, the creation of a continuous process, a decrease in the number of staff, the exclusion of agitation of sludge in the process of extracting it.

The specified technical result is achieved by the fact that in the known device for the collection and transportation of bottom sludge, including a floating body, to the frame of which is attached a system for adjusting the depth of immersion with a flexible coupling and a submersible soil pump, a flexible pressure hose, a working movement mechanism installed on the shore, is connected with floating housing using an annular cable and contains a reversible motor with a gearbox, limit switches mounted at the points of attachment of the annular cable to the floating housing, ro face of the tension of the ring cable and a guide roller for moving the ring cable mounted on a stand on the opposite bank, the peculiarity is that the mechanism of working movements is placed on two mobile platforms, one of which has a reversible motor with a gearbox and a roller of tension of the ring cable, on the second is equipped with a guide roller, while for synchronous movement of the platforms, each of them is equipped with a chain drive, and has rollers for directing the movement of the platforms in pairs llelno oppositely disposed corners, is rigidly attached to the supports.

Figure 1 presents a General view of the device for the collection and transportation of bottom sludge, figure 2 is a top view of the first platform, figure 3 is a top view of the second platform.

The device comprises a floating housing 1, to the frame 2 of which is attached a system for adjusting the depth of immersion 3, comprising a flexible coupling 4 and a submersible soil pump 5, a flexible pressure hose 6 connected to a receiving tank (not shown in the drawing). The device also contains a working movement mechanism, which is installed on the shore and connected to the floating body using an annular cable 7 and contains limit switches 8 and 9 for automatic control, mounted at the points of connection of the cable 7 to the floating body. The mechanism of working movements is placed on two mobile platforms 10 (Fig. 1) and 11 (Fig. 2), on one of which a reversible motor 12 with a reducer 13, a drive pulley 14, which drives the cable 7 and the cable 15 of the cable tension 7 rack 16. On the second platform, a guide roller 17 is installed on the rack 18. For synchronous movement of the platforms 10 and 11, each of them is equipped with a chain drive 19 and 20 and has rollers for guiding the movement of the platforms - 21 and 22 - on the first platform 10 (FIG. .2) and 23 and 24 on the second platform 11 (figure 3) in parallel-pro opposite the angles 25 mounted on the supports 26. The platforms 10 and 11 move on the wheels 27. The electric drives 28 and 29 and gearboxes 30 and 31 respectively serve as the drive for the chain gears 19 and 20.

The device operates as follows.

The assembled floating body attached to the cable 7 is installed on the site of the sludge intake and the immersion depth adjustment system 3 adjusts the required immersion depth of the submersible soil pump 5. Using the roller 15, pull the cable 7, attach the flexible pressure hose 6 to the receiving tank, and simultaneously turn on the power the reversing engine 12 and the power of the submersible soil pump 5. With the translational movement of the floating body, the sludge suspension is fed through a flexible hose 6 and from there to the receiving tank. When the pontoon approaches the shore, automatic switches 8 and 9 are triggered, the movement of the cable 7 stops and at the same time the chain drives 19 and 20 are turned on. When moving the platforms 10 and 11 using the rollers to guide the movements of the platforms 21, 22 and 23, 24 in parallel - opposite the guiding angles 25, the automatic switches 8 and 9 are triggered to the required distance, the chain drives 19 and 20 are turned off and the guide roller 17 rotates the cable 7 in the opposite direction laziness. Next, the cycle repeats.

The device is realizable since All components and parts of it are mastered and produced by industry.
