Abstract

The purpose of the invention is to reduce energy consumption for transportation. After loading containers 2 at the station, they fall into the zone of action of tires 22 and 23. If container 2 has a nominal weight, it continues to move, and within frames 18 and 19, since the distance between frames 18 and 19 and tires 22 and 23 are equal and so great, no current is excited. If the weight of the container 2 is different from the nominal, it is respectively raised or lowered, while the current goes to one of the windings, which will result in pumping out or pumping fluid from the pipeline 1 into it, thereby reducing the zero buoyancy of the containers 2 and eliminating friction against the walls pipeline 1. with with with 23 g fPU2.1

Description

The invention relates to pipeline transport, and in particular to the installation of pipeline hydraulic transport of goods.

The purpose of the invention is to reduce energy costs for transportation.

In FIG. 1 shows an installation, a section in a section behind a metered loading station; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section 10 BB in FIG. 1; in FIG. 4 - node I in FIG. 1 (when removing the downward inclination of the right end of the container); in FIG. 5 electric circuit for turning on the reversible electric motor; in Fig.6 15 and 7 is an electrical diagram of the inclusion of a reversible electric motor of one of the cameras with a two-chamber ballast system.

Installation of pipeline 1, where 20 carrier liquids (not shown) contain single or connected containers 2, which, having passed the loading station with a metering device (not shown), should have ^ 5 zero buoyancy, which ensures their non-contact movement along. main pipeline 1. The installation contains a drive (not shown) for translational movement, which 30 for pressure container transport consists of pump-lock stations located at a given step, and for pressureless pipeline transport, it consists of magnetic solenoid motors or from conveyors with infinite traction bodies mating with each of the containers.

The installation also contains an unloading station, a control system, automation and control.

Each container 2 contains a sealed housing 3 with a lid 4, which allows to open the container 2 to fill it with useful bulk cargo 7 by means of a lever with a roller 5, 45 of the hinge 6 and fixed guide rails of the pipeline 1 (seal 8 prevents 50 falling into the container 2 carrier fluid. At least one ballast chamber 9 is made in the lower part of each container, which is located along the entire length of container 55 nera 2, the volume of which should contain the amount of carrier fluid equal to the tolerance on the weight of the container (the difference is the largest and smallest

2 container weights). The chamber 9 is connected by tubes 10 to the air space 11 located above the payload 7, and its lower part is connected to the inlet 12 of the reversing pump (for example, gear) 13, which is connected by its second inlet 14 to the carrier fluid of the pipeline 1. The reversing pump 13 is connected to the reversing motor (for example, serial) 15, which has two windings of direct 16 and reverse 17, connected one (16) to the upper 18 induction frame installed in the upper part of the housing 3 of the container 2, and the other (17) to the lower frame 19, located from the container 2. Both frames 18 and 19 are separated by diodes 20 and through an armature 21 are connected to the windings 16 and 17. In the pipeline section 1 adjacent to the loading station (not shown), tires 22 and 23 are laid, located respectively at the top and bottom on which the voltage of a high-frequency alternating electric current is supplied. The pipe section 1 where these tires are laid is made of diamagnetic material, and the tires themselves can be located both inside the pipe’s wall and outside, and the number of individual wires in one row is determined by the value of the possible angle of swing of containers around their longitudinal axes.

If the container is designed to transport liquid cargo 24, the installation of the tubes 10 is undesirable, since when the container is inclined, the liquid cargo 24 40 through the tubes 10 can enter the ballast chamber 9, which will disrupt the operation of the entire compensation device. In this case, the ballast chamber can be equipped with a horizontal elastic diaphragm (not shown) that divides the ballast chamber along the entire length into two cavities, while the upper cavity is connected with its upper part to the inlet 12 of the pump 13, and the lower cavity through holes in the container body 3 2 is connected to the carrier fluid of the pipeline.

During operation, it may turn out that the container has zero buoyancy, however, as a result of uneven filling of the payload along its length, one end will be heavier than the other. In this case, container 12999 with its heavy end will scrape along the bottom of the pipeline, and light along the top. All this will negatively affect the amount of energy consumption and the reliability of pipeline transport. $

To eliminate this, it is advisable to divide the ballast chamber 9 across the rigid sealed partition 25 (see Fig. 4) into two chambers: the front 26 and rear 27, and each of the chambers should be equipped with its own reversing pump 28 (29), a reversible electric motor (30) 31 and a pair of induction frames 32, 33 (34, 35). In this case, the electric motor 30 (Fig.7), 15 serving the pump 29 of the front 26. the ballast chamber is connected to the front 32, 33 pair of induction frames located at the front end of the housing 3 of the container 2, and the electric motor 20, the servicing pump 28 of the rear 27. the ballast chamber is connected to the rear 34, 35 pair of induction frames located in the rear end of the casing 3 of the container 2. For the possibility of .25 movement of the containers in the dosing mechanism without friction against the walls of the pipeline 1, guides 36 are provided in it. For this, at the end of the loading mechanism at the bottom of the pipeline 1, a high-frequency bus 37 is installed, interacting with the frames 19 35 or 33, 35.

For normal operation of the proposed device, it is necessary that the weight of each container after the metering device would have a negative tolerance of 40. This means that the dispensing mechanism of the loading station must be configured to underload containers within the margin of error.

For example, if the nominal weight of 45 containers should be 2000 kg, and the permissible error is 3%, then containers with a maximum weight of not more than 2000 kg and a minimum of 50 should leave the dosing mechanism

1940 kg, while if the carrier fluid is water, then the volume of the chamber 9 should be at least 60 liters.

Container loading is carried out on the go. In the dispensing mechanism, when the container in the rails 36 rises above the level of the carrier fluid, and other stationary guides

The pipelines by the lever with the roller 5 raise the lid 4, a predetermined amount of payload is poured into each container. At the same time, a high-frequency electric current is supplied to the bus 37. The tire 37 interacts with the lower frames 19 (33, 35) and includes pumps 13 (28, 29), which completely pump liquid from the ballast chamber 9 (26, 27).

After the containers leave the guides 36, they are in a free state in the zone of action of the tires 22 and 23. Moreover, if the container 2 has a nominal weight and continues to move along the axis of the pipeline, the distance between its frame 18 and the tire 22, as well as the distance between the frame 19 and the bus 23 is equal to each other and so large that in the framework of 18 and 19 there is not enough current to drive the pump 13. The container continues to move axisymmetrically, its chamber 9 does not fill with water and therefore does not change its buoyancy.

If the weight of the container is less than the nominal, then it rises, while the emf excited in the induction frame 18 increases inversely with the cube of the distance. Therefore, when the frame 18 is sufficiently close to the bus 22, the current begins to flow along the forward winding 16 and the pump 13 draws in the carrier fluid from the surrounding space through the inlet 14 and pumps it into the chamber 9 through the inlet 12. The weight of the container becomes nominal, it drops and starts to move axisymmetric. If an excessive amount of liquid is pumped into the chamber 9, the container drops too low and its lower frame 19 begins to interact with the bus 23. The electric current to the engine 15 will go through another winding 17 of the reverse stroke, which will lead to the pumping of excess fluid from the chamber 9 and restoration of zero buoyancy. A small error in the weight of the container will require a small addition of carrier fluid to the chamber 9. With a maximum error in the weight of the container, the chamber 9 should be filled to the top.

If there are two chambers 26 and 27, the container will not only maintain zero buoyancy, but also the horizontal location of its longitudinal axis. So, for example, if, after exiting the dosing mechanism, the front part of the container (see Figs. 4, 6 and 7) is heavier than the rear, then for the electric motor 30 the current gives the lower-5 lower frame 33, as a result of which the pump 29 pumps out liquid from the chamber 26, and the motor 31 is supplied with current by the upper frame 34, as a result of which the pump 28 pumps liquid into the chamber 27. Different weights of the chambers 26 and 27 create a torque returning the longitudinal axis of the container to the horizontal position. If at the same time he did not get zero buoyancy, then the 1s of the pump 28 and 29 will start working in one direction and, if the amount of liquid in the individual chambers 26 and 27 is not the same, they will provide a total amount of liquid in them equal to the total 21 weight loss of the container within the established tolerance .

The purpose of the invention is to reduce energy consumption for transportation. FIG. 1 shows the installation, a section in the area behind the dosed loading station; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section 10 bb in fig. one; in fig. 4 — node I in FIG. 1 (when removing the downward slope of the right end of the container); Fig. 5 shows an electrical circuit for switching on a reversible electric motor; 6 and 5 show the electrical circuit for switching on the reversible electric motor of one of the chambers with a two-chamber ballast system. The installation of pipeline 1, where single or connected to the compositions of container 2, which passed the loading station with a dosing device (not shown), are placed in a 20 carrier fluid, must have zero buoyancy ensuring their contactless movement along the main pipeline 1 The installation contains a drive (not shown) of translational movement, which for the pressure container transport consists of 30 pump-station stations with a predetermined step, and for a pressure-free pipeline ransporta - from the magnetic solenoid 35 GOVERNMENTAL engines or conveyors with endless m govymi bodies engage-expandable with each of the containers. The installation also contains an unloading station 40, a control, automation and control system. Each container 2 contains a sealed enclosure 3 with a lid 4 allowing the lever 2 (45), the hinge 6 and the fixed guide pipe 1 (guides not shown) to open the container 2 to fill it with a useful weight 7. The seal 8 prevents 50 from entering inside the container 2 carrier fluid. At the bottom of each container there is at least one ballast chamber 9, which is placed along the entire length of container 55, the volume of which must contain an amount of carrier fluid equal to the tolerance on the weight of the container (the difference between the largest and the smallest 12 container weights). The chamber 9 is connected to the air space 11 by the tubes 10 located above the payload 7, and its lower part is connected to the inlet 12 of a reversible pump (for example, a gear pump) 13, which by its second inlet 14 is connected to the carrier fluid of the pipeline 1. The reversible pump 13 is connected with a reversible motor (for example, a serial) 15, which has two forward windings 16 and 17 reverse, connected one (16) to the upper 18 induction frame installed in the upper part of the housing 3 of the container 2, and the other (17) to the lower frame 19, located The bottom of container 2. Both frames 18 and 19 are separated by diodes 20 and are connected through a bark 21 to windings 16 and 17. On the section of pipeline 1 adjacent to the loading station (not shown), tires 22 and 23 are located, respectively located on top and from below, to which the voltage of high-frequency alternating electric current is applied. The section of pipe section 1 where these tires are laid is made of diamagnetic material, and the tires themselves can be located both inside the pipe wall and outside, and the number of individual wires in one row is determined by the size of the buildup angle of the containers around their longitudinal axes. . If the container is intended for the carriage of liquid cargo 24, the installation of the tubes 10 is undesirable, since when the container is tilted, the liquid cargo 24 through the pipes 10 may fall into the ballast chamber 9, which will disrupt the operation of the entire compensation tool. In this case, the ballast chamber may be provided with a horizontal elastic diaphragm (not shown) separating the ballast chamber along the entire length into two cavities, while the upper cavity is connected to the inlet 12 of the pump 13 by its upper part, and the lower cavity through the holes in the housing 3 container 2 is connected to the carrier fluid of the pipeline. During operation it may appear that the container has zero buoyancy, however, as a result of uneven loading of the payload along its length — one end will be heavier than the other. In this case, the container 3129 with its heavy end will be scrape along the bottom of the pipeline, and light along the top. All of this will negatively affect the energy consumption and reliability of pipeline transportation. To eliminate this, it is advisable to divide the ballast chamber 9 across the rigid hermetic partition 25 (see Fig. 4) into two chambers: the front 26 and the rear 27, and each with a reversing pump 28 (29) with a reversing electric motor (30). ) 31 and a pair of induction frames 32, 33 (34, 35). When this motor 30 (Fig.7), serving the pump 29 front 26. the ballast chamber is connected to the front 32, 33 pair of induction frames located in the front end of the housing 3 of the container 2, and the electric motor 31 serving the pump 28 of the rear 27. ballast chamber is connected to the rear 34, 35 pair of induction frames located in the rear The end of the container case 3 2. To allow the containers to move in the metering mechanism without rubbing against the walls of the pipeline 1, guides 36 are provided in it. To prepare the ballast chambers 9 for operation, they must be pre-pumped out of the carrier fluid. To this end, at the end of the loading mechanism, a high-frequency bus 37 is installed at the bottom of the pipeline 1, interacting with the frames 19 or 33, 35. For normal operation of the proposed device, it is necessary that the weight of each container after the dosing device has a negative tolerance. This means that the metering mechanism of the loading station must be configured to underload containers within the limits of the error. For example, if the nominal weight of containers should be 2000 kg, and an error of 3% is allowed, then the dosage mechanism should include containers with a maximum weight of not more than 2000 kg and a minimum of 1940 kg, while if the carrier liquid is water, then chamber volume 9 must be at least 60 liters. Containers are loaded from on the go. In the metering mechanism, when the container in the guides 36 rises above the level of the carrier fluid, and the other fixed directions The pipeline with the lever with roller 5 lifts the lid 4, a predetermined amount of payload is poured into each container. At the same time, high frequency electric current is supplied to bus 37. The tire 37 interacts with the lower frames 19 (33, 35) and includes pumps 13 (28, 29), which completely pump out the liquid from the ballast chamber 9 (26, 27). After the containers come off the guides 36, they are in a free state and fall into the zone of actions 22 and 23 In this case, if container 2 has a nominal weight and continues to move along the pipeline axis, the distance between its frame 18 and tire 22, as the distance between the frame 19 and the bus 23 are equal to each other and so large that within 18 and 19 there is not enough current excited to rotate the pump 13. The container continues to move axisymmetrically, its chamber 9 does not fill with water and therefore does not change it buoyancy If the weight of the container is less than nominal, then it rises upwards, while being excited in the induction frame 18, the EMF increases inversely with the cube of the distance. Therefore, with a sufficient approach of the frame 18 to the bus 22, the current begins to flow along the winding 16 of the forward stroke and the pump 13 through the inlet 14 sucks the carrier fluid from the surrounding space, and through the inlet 12 pumps it into the chamber 9. The weight of the container becomes nominal, it lowers and starts move axisymmetrically. If an excess amount of fluid is pumped into chamber 9, the container is lowered too low and its bottom frame 19 begins to interact with the bus 23. Electrically the current into the engine 15 goes through another reverse winding 17, which will cause the excess fluid to be pumped out of chamber 9 and zero buoyancy recovery. A small error in the weight of the container will require a small addition of carrier fluid into chamber 9. With a maximum error in the weight of the container, chamber 9 must be filled to the top. If there are two chambers 26 and 27, the container will not only maintain zero buoyancy, but also the horizontal position of its longitudinal axis. So, for example, if, after leaving the metering mechanism, the front part of the container (see Figs. 4, 6 and 7) is heavier than the back, then for the electric motor 30 a current gives the bottom frame 33, as a result of which the pump 29 pumps out the liquid from the chamber 26, in the motor 31, the current gives the upper frame 34; as a result, the soybean 28 pumps fluid into the chamber 27. The different weights of the chambers 26 and 27 create a torque that returns the longitudinal axis of the container to a horizontal position. If at the same time he did not get zero buoyancy, then both pumps 28 and 29 will start to work in the same direction and with an unequal amount of fluid in separate chambers 26 and 27, they will provide a total amount of fluid in them equal to the total lack of container weight within the prescribed tolerance. formula of invention 2.
