Description

The invention relates to agriculture, in particular, transporting and feeding devices.

A device for transporting highly viscous structured liquids through a pipeline (AS No. 1247623, IPC F17D 1/16, publ, 07.30.1986. Bull. No. 19) The device contains a vibrator connected to an active organ made in the form of a movable section of the pipeline and flexible elements connecting its ends with the pipeline, and flexible elements made in the form of bellows.

The main disadvantage of the known device is that the active organ of the vibrator, applying longitudinal vibration, affects a small layer of the transported medium, thereby reducing the efficiency of transportation of liquids.

The closest technical solution to the problem to be solved is the pipeline for transporting viscous feed mixtures. (Patent No. 179375 of the Russian Federation, IPC F17D 1/16, published on 05/11/2018 Byul. No. 14). The pipeline has a single-wall cylindrical pipe, is provided with a second pipe located outside and having spacers in the radial direction, from the ends the space between the pipes is tightly plugged and on one upper side the second pipe is equipped with a faucet for pumping water and creating a water jacket, and on the other lower side with a faucet water intake. The pipeline is also provided with a third pipe located outside the second pipe and having its own spacers in the radial direction, from the ends the space between the second and third pipe is also tightly plugged and on the one upper side the outer third pipe is equipped with a tap for pumping water and creating a second water jacket, and the other bottom side - a tap for drawing water from the second water jacket.

The main disadvantage of the known pipeline is that during transportation in livestock buildings at a distance of 30-70 m steamed semi-liquid fodder media, therefore, heated to 80-90 degrees Celsius and heating water located in the first water jacket and used for technical purposes, also heating the water located in the second water jacket and used for technical purposes of the second category, they cool down quickly, thereby reducing the efficiency of the pipeline.

The task of the invention is aimed at ensuring that the water heated in the second water jacket from the energy of the feed mixture heat retains its heat for a considerable time and does not waste energy on heating the environment.

The technical result is achieved by the fact that the pipeline for transporting semi-liquid feed media, having a single-wall cylindrical pipe, equipped with a second pipe located outside and having struts in the radial direction, from the ends, the space between the pipes is tightly plugged and from one upper side the second pipe is equipped with a crane for pumping water and the creation of the first water jacket, and on the other lower side - a tap for water intake, also equipped with a third pipe, located outside the second pipe and having its own whips in the radial direction, from the ends, the space between the second and third pipes is also tightly plugged and on the one upper side the outer third pipe is equipped with a tap for pumping water and creating a second water jacket, and on the other lower side - a crane for drawing water from the second water shirt, According to our proposal, it is equipped with a fourth pipe, located outside the third pipe and having its spacers in the radial direction, from the ends the space between the third and fourth pipe is also tightly plugged and on one side The outer fourth pipe is fitted with a valve nipple and a threaded plug for pumping air from the annulus between the third and fourth pipes and maintaining vacuum there.

Such use of the pipeline made it possible to ensure the presence of a vacuum jacket around the third pipe, which retains the high temperature of the heated water in this pipe for considerable time.

The drawing shows the scheme of the proposed pipeline.

The pipeline for transportation of feed mixtures has a single-wall cylindrical pipe 1. The pipeline is equipped with a second pipe 2, located outside and having struts 3 in the radial direction. From the ends of the second pipe, the space is tightly plugged with end plugs 4. On the one upper side, the second pipe is equipped with a tap for pumping water 5 and creating a water jacket, and on the other lower side with tap 6 for drawing water for technical purposes. The pipeline is provided with a third pipe 7, located outside the second pipe and having its spacers 8 in the radial direction. From the ends, the space between the second and third pipes is also tightly plugged with end plugs 9. On the one hand, the outer third pipe is equipped with a tap 10 for pumping water between the second and third pipes, and on the other lower side with a tap 11 for drawing heated water. The pipeline is provided with a fourth pipe 12 located outside the third pipe and having its spacers 13 in the radial direction. From the ends, the space between the third and fourth pipes is also tightly plugged with end plugs 14. On the one hand, the outer fourth pipe is equipped with a nipple 15 with a valve and a threaded plug for pumping air from the annular space between the third and fourth pipes and maintaining vacuum there (the design of the nipple in the circuit is conventionally not shown).

The pipeline works as follows:

The prepared feed mixture, pre-steamed, is fed into the pipeline at a temperature of 80-90 degrees using a special pump. Pipe 1, through which the finished mixture is transported, is grasped by a water jacket, and the heat energy of this mixture is spent on water heating, up to 50-60 degrees Celsius, which is then used for technical purposes. Spacers 3 maintain the required distance between the pipes. The plugs 4 ensure the tightness of the water jacket, and the tap 5 and the tap 6 make it possible to pour water and take it hot for technical purposes of the first category, for example, for washing milking machines. Since the pipe 2 in which the heated water is located, is wrapped around its water jacket located between the second 2 and third 7 pipes, the water retains high temperature in the first water jacket for a long time. Spacers 8 supports the required distance between the second and third pipes. Plugs 9 provide tightness of the annular space, and taps 10 and 11 provide an opportunity to pour water and take it hot for technical purposes of the second level, for example, for washing hands. Since the pipe 7 in which the heated water is located for technical purposes of the second category, is wrapped around a vacuum space located between the third 7 and the outer 12 pipes, the water in the pipe 7 maintains a high temperature for a long time. The spacers 13 maintain the required distance between the third and fourth tubes. The plugs 14 provide the tightness of the annular space, and the nipple 15 makes it possible to maintain the vacuum at the desired level.

Thus, the task of the invention is fully accomplished.
