Abstract
Animal waste is divided into liquid and solid fractions by a separator comprising an upper reservoir 11 from which the waste overflows on to a downwardly sloping filter screen 12, through which the liquid passes into a chamber 13 whose lower end is divided by a baffle 131. A vacuum pump 16 applies variable suction to the space to the right of the baffle and thence to the lower part of screen 12 to assist filtering, while filtering through the rest of screen 12 is by gravity only. All the liquid is discharged from chamber 13 through a common drain opening. A water sprinkler pipe 15 is moved up and down the screen to assist filtering. The inclination of the screen is adjustable. <IMAGE>
Description
SOLID-LIQUID SEPARATING DEVICE
This invention relates to a vacuum-operated solid-liquid waste separating device.
Environmental pollution has become a problem of worldwide concern, air and water pollutions are most seriously and directly threatening to the living conditions of people, especially those living in urban regions. Governments of most industrial countries have imposed restrictive regulations and laws on factories, hospitals, farms, laboratories and the like so as to prevent further deterioration of the environmental qualities.
Animals' wastes produced on farms usually were released directly into rivers, streams or creeks in most countries without being processed, resulting in the gradual pollution of rivers.
To cope with this sort of water pollution, especially caused by the animals' waste released from livestock farms, a number or ways have been developed to process the waste. One of the most popular prior art solid-liquid separating devices comprises a waste reservoir, a separation tank and a vibration means.
There are a number of disadvantags / associated with the respective components there###i en as below: 1. Waste reservoir; the mixture of the waste is pumped into the waste reservoir directly by a pump, causing the mixture in the waste reservoir to be splashed constantly, resulting in the waste being intermittently led to the separation tank in a splashing manner.
2. Separation tank; the mixture of waste is filtered only by a horizontally disposed filter net in a natural manner with the liquid of the waste passing therethrough so to effect the separation.
This kind of separation is slow and lacks efficiency. Once the sticky waste makes the filter net cease to function, accumulation of the waste will interrupt the whole operation.
3. Vibration device; which is based on a motor operated crank member. This type of device has a relatively complicated structure and is high in cost. Frequent mechanical disorders thereof also constitute another disadvantage.
The present inventor has noticed the problems and devoted his time to designing an improved vacuum operated solid-liquid separating device which is easy to maintain and effective to operate.
The primary object of the present invention is to provide an improved vacuum operated solid-liquid separating device adapted for processing animals' waste before it is released into a river, stream or the like so as to prevent the same from pollution.
According to the present invention there is provided a solid-liquid separating device comprising an upper reservoir disposed at the top portion of the separating device for receiving a solid-liquid mixture, the upper reservoir having an outlet through which overflowing mixture can be discharged, a horizontal fluid guide board disposed at the outlet of the upper reservoir, an upper filter member connected to one end of the horizontal fluid guide board and inclined downwardly therefrom, a lower filter member disposed under said upper filter member with a lower reservoir disposed at the bottom end thereof, said lower reservoir being divided by a partition board into a right and a left chamber which are in communication with each other at the bottom end of said partition board, the space between said upper filter member and lower filter member being divided into two areas, in said right chamber an air suction tube being disposed, the air suction tube being coupled to a vacuum generating device, a drain tube being disposed at the bottom of said left chamber of said lower reservoir.
Preferably, the solid-liquid mixture processed by the device is animal's waste, in particular the waste of farm livestock.
In one embodiment of the present invention there is provided a water guard board at the lower end of the upper filter member for purposes of facilitating the drawing of liquid waste into the lower reservoir without such being sucked into the air suction tube of the vacuum generating device.
In another embodiment of the present invention there is provided a water-sprinkling device located on top of the upper filter member and adapted for scattering clean water over the surface of the upper filter member so to prevent the same from being clogged with sticky solid waste, the mixture of clean water and the liquid waste being drawn into a reservoir as a result of a vacuum state produced by the vacuum generating device.
Preferably, the water-sprinkling device is moveable. It may be connected to a pump which pumps water to the sprinkling device, preferably, from a reservoir disposed in solid-liquid separating device. The water-sprinkling device may also be connected to a motor to facilitate motion of the water-sprinkling device.
In one embodiment of the invention the water-sprinkling device is slidably positioned over the upper filter layer, a motor being preferably used to facilitate the sliding motion. The water-sprinkling device may be slidably mounted on a pair of looped wires positively engaged with a motor.
In another embodiment of the present invention there is provided a solid-liquid separating device wherein the upper filter member and the lower filter member are adjustable in their inclination by means of an adjusting wheel so that the flowing speed of liquid waste can be selected as desired.
A further embodiment of the present invention provides a solid-liquid separating device wherein the vacuum generating unit can be adjusted for producing vacuum states of various level. This adjustment is preferably achieved by the provision of a flexible tube connecting the vacuum generating device and the air suction tube disposed in the right chamber. This flexible tube may have an adjustable opening positioned therein near the end connected to the vacuum generating device.
In a further embodiment of the present invention there is provided a pump and conduits for purposes of pumping solid-liquid mixture from a reservoir of such to the top reservoir of the solid-liquid separating device.
Preferred embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Fig. 1 is a diagram showing the perspective view of the present invention;
Fig. 2 is a diagram showing the sectional view of the present invention; and
Fig. 3 is a diagram showing the adjustment of the upper and lower filter members by way of an adjusting wheel.
Referring to Figs. 1, 2, the vacuum-operated solid-liquid separating device 1 comprises an upper reservoir 11, an upper filter member 12, a lower reservoir 13, a lower filter member 12, a lower reservoir 13, a lower filter member 14, a water sprinkling device 15 and a vacuum generating unit 16.
The mixture of waste produced by the livestock is first pumped to the upper reservoir 11 disposed at the top of a frame structure by a pump 17 coupled to the reservoir 11 by way of a flexible tube 18. At the outlet of the upper reservoir 11 is disposed a horizontal fluid guide board 111 which permits the mixed waste to flow down along the sloped upper filter member 12, and a water guard board 121 is located at the lower end of the filter member 12 so as to lead the liquid waste to the lower reservoir 13 for effecting primary separation. A water sprinkling device 15 is slidably mounted on a pair of tracks, which are substantially parallel with the filter member 12 and is actuated by a speed reducing motor 19 so that the same can be moved steadily back and forth in the water sprinkling operation.The slidable water sprinkling device 15 is coupled to a water pump 17, by a flexible conduit 181, which is connected to a water tank 20 so that clean water therefrom can be scattered all over the filter member 12 repeatedly, preventing solid waste from sticking to the surface of the filter member 12.
The lower filter member 14 is disposed below the upper filter member 12 at a selected angle which can be adjusted by means of an adjusting unit 21 so as to vary the speed of the downward flowing fluid. At the terminal end of the lower filter member 14 is located a lower reservoir 13 which is divided by a partition board 131 into a left chamber 132 and a right chamber 133 in communication with each other at the bottom thereof. The partition board 131 is also used to define two areas having different air pressure. The waste liquid separated in the primary process through the upper filter member 12 along with the scattered clean water dispensed by the water-sprinkling device 15 is delivered to the lower filter member 14.
The vacuum-generating unit 16 draws the mixture into the lower reservoir 13, with the gas produced therein expelled out thereof and the solid portion of the waste slides downward along the upper filter member 12, and piles up on the floor or the like.
An opening 162 is disposed at the bottom of a coupling 161 associated with the vacuum generating unit 16, a flexible or extensible tube 163 is used to couple the vacuum generating unit 16 and an L-shaped pipe 135 disposed in the right chamber 133; and the opening 162 can be adjusted by the extensible tube 163 so that the degree of suction can be varied, permitting the suction force of the vacuum generating unit 16 to be reduced when the amount of waste to be processed is small.
