Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An excreta solid-liquid separation device 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.
The excreta solid-liquid separation device 100 according to the embodiment of the present invention, as shown in fig. 3 to 4, includes: a separation chamber 2, a solids chamber 3 and a baffle 4.
The bottom of the separation chamber 2 is provided with a spaced apart solids outlet 22 and a liquid outlet 23, the solids chamber 3 being located below the separation chamber 2 and the solids chamber 3 being in communication with the solids outlet 22.
The baffle 4 is movably arranged at the solid outlet 22, and the baffle 4 is used for opening or closing the solid outlet 22. The baffle 4 closes the solids outlet 22 when excrement is discharged into the separation chamber 2.
The working principle of the excrement solid-liquid separation device 100 is as follows: the baffle 4 closes the solids outlet 22 before the effluent is discharged from the discharge inlet 21 of the separation chamber 2 into the separation chamber 2. After the separation chamber 2 has been drained of excrement, the drained liquid fraction can flow out of the liquid outlet 23. After the liquid has completely flowed out of the separation chamber 2, the flap 4 is opened and the solid waste in the separation chamber 2 can fall from the solid outlet 22 into the solid chamber 3. In this way, the liquid portion and the solid portion of the excrement in the separation chamber 2 are discharged from the liquid outlet 23 and the solid outlet 22, respectively, thereby achieving the purpose of solid-liquid separation.
For convenience of understanding, the operation mode of the excrement solid-liquid separation apparatus 100 is described below by taking a specific example as an example:
when urine is discharged into the separation chamber 2, the baffle 4 closes the solid outlet 22 and urine is discharged from the liquid outlet 23;
when excrement such as urine, excrement and the like is discharged into the separation cavity 2, the baffle 4 closes the solid outlet 22, the urine is discharged from the liquid outlet 23, the device judges that the urine is completely discharged after the excrement stops being discharged for ten minutes, then the driving piece of the baffle 4 drives the baffle 4 to be opened, so that the excrement remaining after the urine is completely discharged is discharged into the solid cavity 3, the device judges that the excrement is completely discharged after the baffle 4 is opened for five minutes, and then the driving piece of the baffle 4 drives the baffle 4 to close the solid outlet 22;
when water flow and detergent are flushed into the separation chamber 2 for cleaning, the baffle 4 closes the solid outlet 22, and the cleaning water is discharged from the liquid outlet 23;
when the excrement solid-liquid separation device 100 is not in use, the baffle 4 closes the solid outlet 22 to block the malodorous smell in the solid chamber 3 from escaping from the solid chamber 3.
The excrement solid-liquid separation device 100 does not need to be additionally provided with a solid-liquid separation mechanism, so that the structure of the device is simplified, the volume is reduced, and the energy consumption is reduced.
Specifically, the excrement solid-liquid separation mechanism disclosed in the related art includes a belt conveyor provided below the inlet of the toilet, and after excrement falls down onto the belt, the solid portion is sent to the excrement collection chamber by the belt, and the liquid portion flows down along the belt to the liquid collection place. The belt conveying piece is large in size and high in energy consumption. Therefore, in the embodiment of the invention, the belt conveying part is saved, the structure of the device is obviously simplified, the structural layout is simple and reasonable, the cost is low, and the after-sale maintenance rate is low.
In the embodiment of the invention, the urine and the excrement can be respectively treated after being separated, thereby facilitating the subsequent treatment of the excrement. For example, urine can be directly applied after dilution or degradation, and feces can be degraded and converted into organic fertilizer, etc. After the urine and the excrement are separated at one time, the treatment is easy, the secondary pollution is avoided, and the water quantity required by the treatment is reduced.
According to the solid-liquid separator 100 for excrement of the embodiment of the invention, the baffle 4 which can be opened and closed is arranged at the solid outlet 22 of the separation cavity 2, when excrement is discharged, the baffle 4 blocks the solid outlet 22, so that the liquid part in the excrement is automatically discharged from the liquid outlet 23, and after the liquid is discharged for a period of time, the baffle 4 can be opened again, so that the solid part in the excrement can fall into the solid cavity 3. The baffle 4 is utilized to enable liquid and solid in excrement to be discharged out of the separation cavity 2 in sequence, the device is low in energy consumption and simple and reasonable in layout, environmental pollution is reduced, subsequent urine and excrement can be conveniently treated respectively, and the amount of water used for treatment can be reduced.
Here, as shown in fig. 3 and 4, the excrement discharged into the separation chamber 2 freely falls down to the bottom of the separation chamber 2 by gravity. Wherein the solid outlet 22 is located below the discharge opening 21 and the projection of the discharge opening 21 onto the horizontal plane is located within the projection of the solid outlet 22 onto the horizontal plane, i.e. if there is an excrement discharge from the discharge opening 21, most of the excrement will fall vertically onto the baffle 4 at the solid outlet 22 under the action of gravity, so that the solid excrement can automatically fall into the solid chamber 3 after the liquid part of the excrement flows out from the liquid outlet 23 and the baffle 4 is opened.
Of course, the projection of the discharge inlet 21 onto the horizontal plane in the embodiment of the invention may also be partly within the projection of the solids outlet 22 onto the horizontal plane, i.e. if there is discharge from the discharge inlet 21, part of the discharge falls on the baffle 4 and part of the discharge falls on the bottom wall of the separation chamber 2 adjacent to the solids outlet 22. When the shutter 4 is opened, the solid waste located on the shutter 4 falls by gravity into the solid chamber 3. However, it can be understood that the solid waste has a certain viscosity, and when the baffle 4 is opened, the solid waste on the baffle 4 falls into the solid chamber 3 under the action of gravity, and the fallen solid waste can adhere to other solid waste and fall into the solid chamber 3, so that the purpose of discharging the solid waste can be achieved.
Or in a specific example, a sweeper (not shown) may be provided within the separation chamber 2, the sweeper being movable to sweep solids within the separation chamber 2 towards the solids outlet 22 when the solids outlet 22 is open and being deactivated when the solids outlet 22 is closed.
In some embodiments, as shown in fig. 3, 4 and 6, an annular plate 24 is arranged in the separation chamber 2, the annular plate 24 extends upwards from the bottom edge of the peripheral wall of the separation chamber 2 along the inward extending rear bend, an upper open collecting tank 241 is defined between the annular plate 24 and the peripheral wall of the separation chamber 2, the surrounding part of the annular plate 24 forms the solid outlet 22, and the liquid outlet 23 is arranged on the peripheral wall of the collecting tank 241.
That is, the annular plate 24 constitutes a bottom wall of the separation chamber 2, a central portion of the bottom wall of the separation chamber 2 forms the solids outlet 22, and a peripheral portion of the bottom wall of the separation chamber 2 is formed with the collection tank 241. When liquid flows down along the peripheral wall of the separation chamber 2 or the liquid flowing into the separation chamber 2 splashes around on the peripheral wall, the liquid flowing down on the peripheral wall can flow into the collecting tank 241, and the liquid flowing into the collecting tank 241 flows out from the liquid outlet 23. The arrangement is more beneficial to discharging the liquid discharged into the separation cavity 2 after being collected.
Form the collecting vat 241 into the annular, be favorable to collecting the liquid excrement from baffle 4 all around, it is more convenient to collect for liquid exhaust velocity improves device solid-liquid separation effect.
Specifically, as shown in fig. 3, when the baffle 4 closes the solids outlet 22, the upper surface of the baffle 4 is flush with the upper surface of the annular plate 24 or higher than the upper surface of the annular plate 24.
Here, for convenience of the subsequent description, the upper surface of the baffle 4 when the solid outlet 22 is blocked is referred to as a working surface S of the baffle 4. If there is a discharge, the waste can fall onto the working surface S of the baffle 4.
When the collecting gutter 241 is provided around the baffle 4 and the working surface S of the baffle 4 is higher than the upper surface of the annular plate 24, the liquid fraction of the excrement flows automatically downwards under the influence of gravity, flowing into the collecting gutter 241 around the baffle 4.
It can be seen that by arranging the upper surface of the baffle 4 flush with the upper surface of the annular plate 24, or by arranging the upper surface of the baffle 4 higher than the upper surface of the annular plate 24, liquid accumulation on the baffle 4 and liquid flow from the solids outlet 22 into the solids chamber 3 after the baffle 4 is opened can be avoided.
Of course, the embodiment of the present invention does not exclude the solution that the upper surface of the baffle 4 is lower than the upper surface of the annular plate 24, and in this case, in order to facilitate the liquid discharge from the baffle 4, a notch (not shown) communicating with the collecting groove 241 may be provided on the annular plate 24. When liquid flows onto the baffle 4, it can flow from the gap into the collecting trough 241 and then be discharged from the liquid outlet 23. However, with this arrangement, the rate of liquid removal from the baffle 4 is relatively slow.
Further, as shown in fig. 4, the liquid outlet 23 is disposed at the lowest position of the collecting tank 241, so as to facilitate the liquid in the collecting tank 241 to flow out from the liquid outlet 23.
Wherein an upper surface of the baffle 4 is disposed obliquely toward the liquid outlet 23 when the baffle 4 closes the solid outlet 22. That is, when the liquid falls on the baffle 4, the liquid can automatically flow toward the liquid outlet 23 by gravity, so that the liquid outflow path is shortened, the liquid discharge speed is increased, the discharge effect is enhanced, and the solid-liquid separation effect of excrement is improved.
However, the inventor found through experiments that when the baffle 4 closes the solid outlet 22, when the included angle between the upper surface of the baffle 4 and the horizontal plane is too large, the solid waste falling on the baffle 4 easily slides to the liquid outlet 23, so that the solid waste flows into the collecting tank 241 or blocks the liquid outlet 23, which is not beneficial to discharging the liquid. When the angle between the upper surface of the baffle 4 and the horizontal plane is too small, the speed of the liquid falling on the baffle 4 flowing to the liquid outlet 23 is too slow, which affects the separation efficiency of the excrement solid-liquid separation device 100.
After the inventor counts the final experimental data, the inventor finds that when the baffle 4 closes the solid outlet 22, and the included angle between the upper surface (i.e., the working surface S) of the baffle 4 and the horizontal plane is 5-8 degrees, the liquid discharging effect on the baffle 4 is good, and the solid discharging is not affected.
Further, as shown in fig. 6, the bottom wall of the collecting tank 241 is also angled with respect to the horizontal, i.e. the bottom wall of the collecting tank 241 is inclined, and the liquid outlet 23 is arranged at the lowest position of the collecting tank 241.
Advantageously, the annular plate 24 is also arranged obliquely, and the annular plate 24 is inclined downwards in the direction towards the liquid outlet 23.
Advantageously, as shown in fig. 6, reinforcing ribs 242 are provided between the annular plate 24 and the peripheral wall of the separation chamber 2, thereby improving the reliability of the connection between the annular plate 24 and the peripheral wall of the separation chamber 2. Alternatively, the reinforcing rib 242 is plural, and the plural reinforcing ribs 242 are provided at both sides of the liquid outlet 23.
In some embodiments, as shown in fig. 6, the circumferential wall of the separation chamber 2 is provided with a flushing port 25 arranged towards the solids outlet 22. Thus, after the solid outlet 22 is closed by the baffle 4, water or detergent can be flushed through the flushing port 25 to flush and clean the sticky solid excrement on the baffle 4, and the flushing water flow can also flush the collecting tank 241, so that the generated flushing sewage can be discharged from the liquid outlet 23.
Specifically, as shown in fig. 3 to 4, the excrement solid-liquid separation device 100 further comprises a flushing pipe 26, and the flushing pipe 26 extends into the separation chamber 2 from the flushing port 25.
Alternatively, the flushing pipe 26 may flush high pressure water, which may enhance the cleaning of the baffle 4 under the impact of the high pressure water.
In some embodiments, as shown in fig. 3 and 4, the baffle 4 is rotatably disposed in the solid chamber 3, when the baffle 4 closes the solid outlet 22, the working surface S of the baffle 4 faces upward to contain excrement, and the working surface S of the baffle 4 is the upper surface of the baffle 4. When the baffle 4 opens the solids outlet 22, the working surface S of the baffle 4 rotates downward about the axis of rotation 42 of the baffle 4, and finally when the solids outlet 22 is fully open, the working surface S is disposed downward or inclined downward. With this arrangement, the discharge of solid waste can be achieved very simply.
Advantageously, as shown in fig. 3, the liquid outlet 23 is provided on the opposite side of the rotation axis 42 of the shutter 4, and the working surface S of the shutter 4 extends obliquely downward in the direction from the rotation axis 42 to the liquid outlet 23 when the shutter 4 closes the solid outlet 22.
Advantageously, as shown in fig. 4, the working surface S of the baffle 4 is disposed obliquely downward when the baffle 4 opens the solids outlet 22. Wherein, the working face S of baffle 4 is certain contained angle with vertical, and the working face S of baffle 4 is in decurrent state to solid waste can break away from baffle 4 more fast on the baffle 4.
Alternatively, the rotation angle of the shutter 4 is greater than 90 degrees when the shutter 4 rotates from the state of closing the solid outlet 22 to the fully opened state.
Specifically, as shown in fig. 1 and 2, the rotary driving member 51 of the baffle 4 is a motor, but the rotary driving member 51 of the baffle 4 does not exclude an electromagnetic pump, a pneumatic pump, or the like. For simplicity, the following description will be given by taking a motor as a rotary driving member of the baffle 4 as an example.
More specifically, as shown in fig. 1, a plurality of flush pipes 26 extend into the separation chamber 2, and the plurality of flush pipes 26 are spaced apart from each other. Advantageously, as shown in fig. 1, the number of the flush pipes 26 is two, the flush pipes 26 are at an angle of 90 degrees, and the flush pipes 26 are symmetrically arranged on both sides of the rotation axis 42 of the baffle 4.
In some embodiments, the peripheral wall of the solid chamber 3 is provided with an air blowing port for blowing air onto the working surface S of the baffle 4. When the baffle 4 opens the solid outlet 22, the blowing port blows air towards the working surface S of the baffle 4, so that the solid excrement on the baffle 4 is quickly separated from the baffle 4 and falls downwards.
