Description

The invention relates to devices for supplying volumes of liquid to consumers at various time intervals with adjustable water hammer. In particular, the drainage device can be used in hydraulic systems for manure removal in livestock farms when washing manure channels and transverse collectors, as flushing tanks of an adjustable volume of drained liquid.

Known drain device manure channels of manure removal systems of livestock farms, including a support on which is mounted a motionless flushing tank made in the form of a closed container with a multifaceted cross-section, with an upper inlet connected through a pipeline and tap to a water supply system and a lower drain equipped with a flush pipe and a valve [ one].

The disadvantage of such a drain device is the insufficient rate of discharge of the liquid volume, limited by the flow sections of the flush pipe and valve, necessary to create a water hammer.

Closest to the invention in technical essence and the achieved effect is a drainage device comprising a housing with a closed volume and nozzles for filling and discharging water, a vessel with an opening for its accumulation, mounted rotatably with the possibility of tipping over in the housing until it stops and then returning it to its original position [ 2].

However, the known design of the drainage device has a complex structure due to the storage vessel placed in another vessel (body). Another disadvantage that determines the main technical characteristic of the device is the insufficient rate of discharge of the accumulated volume of liquid, limited by the bore of the water outlet pipe, the inability to dose control the volume of filling the vessel with drained liquid and discharge at certain intervals.

The basis of the present invention is the task of resetting the estimated volume of liquid at a given speed, creating a hydraulic shock, another task is to create a device that provides the ability to adjust the volume of filling the vessel with liquid and discharge at regular intervals.

The problem is solved in that the drain device according to the invention, like the known one, contains a vessel with holes for filling and discharging water, mounted rotary with the possibility of tipping over and subsequent return to its original position.

For this, the vessel is equipped with a chamber for adjusting the volume of filling the vessel with liquid and dividing along the bottom in a plane transverse to the turning path into two compartments, a partition whose height is less than the height of the walls of the vessel. A chamber for adjusting the volume of filling is formed by a visor located in the upper part of the vessel between its walls, in which at least one overflow valve is mounted. The holes for filling and discharging the liquid are located in the upper part of the vessel and are separated by a valve mounted with the possibility of adjusting movement, while the filling hole is located above the left compartment, and the outlet above the right one.

The device is illustrated in the drawing. Figure 1 schematically shows a device in isometric projection; figure 2 is a longitudinal section along aa in figure 1 with showing the septum, a visor and a valve, figure 3 a section along bb in figure 2 - shows a connection of the valve with the wall of the housing; figure 4 is a view along arrow B in figure 2; figure 5 - schematically the initial position of the vessel; figure 6 - vessel in a horizontal position; Fig.7 - the vessel is filled with liquid; in Fig.8 - the vessel is capsized for emptying.

The drain device comprises a box-shaped body 1 (it may be another shape, for example, cylindrical) and includes a bottom 2, side walls 3 and 4, left 5 and right 6, a valve 7, dividing the upper part of the body 1 into a drain 8 and for pouring liquid 9 holes forming a vessel. On the bottom 2, a partition 10 is installed with a height of a lower height of the housing walls, forming the left 11 and right 12 compartments with the base area of the left 11 compartment larger than the right 12.

In the upper left part of the vessel there is a chamber 13 for adjusting the volume of filling the vessel with liquid, formed by the side 3, 4 and left 5 walls, as well as a visor 14 located between them and inclined at an angle α to its left wall 5. The shutter 7 is made in the form of a plate, mounted on the ends of the walls 3 and 4 with the possibility of a known method of moving along them and fixing using a threaded connection 15 or other known method. The visor 14 is equipped with several overflow valves 16, placed one above the other from the base 17 of the visor 14. The valves 16 are nozzles 18 with threaded covers 19. The vessel, by means of pins 21 and 22, mounted respectively in the side walls 3 and 4 of the housing 1, is held on bearing supports 23 and 24. The asymmetric arrangement of the axis of rotation of the pins 21 and 22 relative to the left and right parts of the vessel creates an imbalance of the system.

The position in which the vessel body 1 is in a horizontal position (FIG. 6) is determined by the stop 25. The mass of the left side of the body 1 in the empty state relative to the axis of rotation of the pins 21 and 22 is greater than the mass of the right side. The location of the pins 21 and 22 is selected taking into account the mass of the left and right parts of the vessel so that in the empty position due to the imbalance, it will self-return to a hovering initial position (Fig. 5) for liquid to enter the left compartment 11. Wall 6 is inclined to the bottom 2 under a blunt angle to reduce the angle of the vessel topple when draining the liquid.

The device operates as follows. The liquid from the system, for example, the water supply, depending on the established procedure for emptying the vessel, is supplied under pressure or without it, thereby determining the time of its filling. Into the vessel in the initial position (Fig. 5), the incoming liquid into the compartment 11 creates an imbalance in the system, in which the mass of the left part of the vessel increases and the vessel smoothly takes a horizontal position (Fig. 6). Subsequently, the liquid fills the vessel to the level of the lower overflow valve 16 with the cover 19 removed. Under the visor 14, the available air creates back pressure and the liquid inside the chamber 13 does not rise above the lower valve 16. The incoming liquid continues to fill the vessel until the right side of the vessel creates a counterweight to the pins 21 and 22 left of the rotation axis. Due to the imbalance formed, the vessel will tip over. The liquid through the window 8 due to its large area with high speed and its instantaneous volume is discharged, creating a powerful hydraulic shock, and enters the channel with manure (not shown in the drawing), flushes it into the receiver. Depending on the required amount of water hammer, the area of the drain window 8 can be adjusted up or down by moving the valve 7 by loosening the threaded connection 15 and then tightening it. After emptying the vessel due to imbalance of the vessel, the latter returns to a hovering initial position. The liquid entering the left 11 compartment creates the opposite tilting moment of the self-return of the vessel until it stops 25. The process is then repeated.

If it is necessary according to the technological regulations to increase the volume of the drained liquid, the lower overflow valve 16 closes and the required upper valve in the row opens.

The device can be used on livestock farms with an adjustable cycle of filling and draining the liquid, due to overflow valves its metered filling is provided, which is especially important when raising pigs. When moving to another age group, the volume of feces emptying changes, therefore, an increased volume of liquid is required to wash it off. By closing the bottom valve with a stopper and opening the required upper one, we increase the volume of filling the vessel.
