Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments, as would be apparent to one of ordinary skill in the art from this disclosure.

Next, the specific structure of the solid-liquid separator in the embodiment of the present application will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a solid-liquid separator in one direction according to an embodiment of the present disclosure; FIG. 2 is a schematic perspective view of the solid-liquid separator shown in FIG. 1 in another direction; FIG. 3 is a schematic front side view of the solid-liquid separator shown in FIG. 1; FIG. 4 is a schematic sectional view in the A-A direction of the solid-liquid separator in FIG. 3. As shown in fig. 1 to 4, the solid-liquid separator in the embodiment of the present application includes: a housing 100, a roller 200, a motor 300, and a lamination roller 400.

The housing 100 may be a shell-shaped member made of a metal frame, a metal plate, or the like, the housing 100 is provided with a feed port 110, and the feed port 110 may be disposed on the top of the housing 100 as shown in fig. 1 to 4, or may be disposed on the side of the housing 100 or other suitable positions, which is not limited thereto. The feed inlet 110 may be in a quadrangular frustum shape, and in particular, the closer the feed inlet 110 is to the mouth, the larger the size of the feed inlet 110 is, so as to facilitate the feces to enter the interior of the casing 100 through the feed inlet 110.

The roller 200 is disposed in the housing 100 and horizontally disposed at a downstream side of the inlet 110, i.e., after the stool enters the housing 100 through the inlet 110, the stool falls down on the roller 200 by gravity. The motor 300 may be disposed on the housing 100, for example, may be disposed on an outer surface of the housing 100, and is in driving connection with the roller 200, and the rotation of the motor 300 may drive the roller 200 to rotate.

The laminating roller 400 is provided in plural in parallel with the roller 200, and may be provided in two as shown in fig. 4, for example. The plurality of laminating rollers 400 are arranged along the circumferential direction of the roller 200, for example, are disposed along a side where the roller surface moves downward when the roller 200 rotates, and the roller surface of the laminating roller 400 can be in contact with the roller surface of the roller 200.

By the above, when excrement is required to be rolled for multiple times, the rolling of the excrement for multiple times can be realized by arranging the rolling rollers 400 at the positions of one side of the downward moving roller surface when the rollers 200 rotate, so that the number of the rollers 200 can be reduced, the space occupied by the solid-liquid separator is reduced, and the miniaturization of equipment is facilitated. Meanwhile, the solid-liquid separation capability of the solid-liquid separator on the excrement can be improved, and the solid-liquid separation effect of the excrement is improved.

As shown in fig. 1 and 2, an air bag 500 is further mounted on the housing 100, and the air bag 500 is in transmission connection with the laminating roller 400. The roll surface of the rolling roll 400 is driven to abut against the roll surface of the roll 200 by inflating or deflating the air cell 500 to adjust the volume of the air cell 500. In addition, the air bag 500 may be replaced with a hydraulic rod, an air cylinder, or other devices that can drive the rolling roller 400 to move, which is not limited.

From above, the rolling roller 400 can be abutted against the roller 200 under the driving of the air bag 500, so that after the excrement enters the shell 100 from the feed port 110, the excrement can be rolled by the roller 200 and the rolling roller 400 arranged at the lower position of the feed port 110, so that the water in the excrement is extruded out, the water can drop through the roller 200, and the solid-liquid separation is realized. Meanwhile, the size of the rolling force between the rolling roller 400 and the roller 200 can be controlled by the air bag 500, so that the rolling force can be adjusted according to the parameter requirements of the water content of the excrement and the like, and the solid-liquid separation effect of the excrement is ensured.

As shown in fig. 1 and 2, the air bag 500 and the laminating roller 400 may be in transmission connection through a driving arm 600, and specifically, the driving arm 600 is hinged to the housing 100 at an intermediate position thereof, so that the driving arm 600 can rotate on the housing 100. One end of the driving arm 600 is connected to the end of the laminating roller 400, and the other end of the driving arm 600 is connected to the airbag 500. The driving arm 600 forms a lever structure between the rolling roller 400 and the air bag 500, and the air bag 500 drives the driving arm 600 to rotate, so that the rolling roller 400 is driven by the driving arm 600 to abut against the roller 200, and the excrement is rolled to realize solid-liquid separation. Meanwhile, the airbag 500 is in transmission connection with the rolling roller 400 through the driving arm 600, so that the airbag 500 can avoid other devices, the degree of freedom of installation of the airbag 500 can be improved, and the installation position of the airbag 500 is more reasonable.

As shown in fig. 1 and 2, the distance from the hinge position of the driving arm 600 to the housing 100 to the rolling roller 400 is smaller than the distance from the airbag 500. According to the lever principle, the force between the rolling roller 400 and the roller 200 driven by the air bag 500 can be amplified through the lever structure formed by the driving arm 600, so that the rolling force of the rolling roller 400 and the roller 200 on the excrement is improved, the solid-liquid separation capability of the excrement is improved, and the solid-liquid separation effect of the excrement is improved.

As shown in fig. 1 and 2, the air cell 500 may be provided in a plurality, and the plurality of air cells 500 are provided in pairs at corresponding positions at both ends of the laminating roller 400. Accordingly, the driving arms 600 are provided in pairs at corresponding positions at both ends of the laminating roller 400 so that the air bags 500 drive the laminating roller 400 to abut against the rollers 200 at both ends of the laminating roller 400. Therefore, the force of the air bag 500 for driving the rolling roller 400 is more uniform, and the solid-liquid separation effect of the excrement is improved.

As shown in fig. 4, the lower portion of the housing 100 is further provided with a discharge hole 120, and in particular, may be provided at a lower portion of the roller 200, such as a suitable position at the bottom or side of the housing 100. The housing 100 is further provided with a discharge guide plate 130, the discharge guide plate 130 is disposed in an inclined manner, one end of the discharge guide plate 130 abuts against the lower surface of the roller 200, and the other end of the discharge guide plate 130 abuts against the discharge port 120. So that the fecal solids completing the solid-liquid separation can be guided to the discharge port 120 through the discharge guide 130 to be discharged.

As shown in fig. 4, a shaving plate 140 may be further disposed inside the housing 100, and in particular, the shaving plate 140 may be disposed at a position between the lower lamination roller 400 and the discharge plate among the plurality of lamination rollers 400. One side edge of the shaving plate 140 abuts against the roller surface of the roller 200, so that the solid excrement attached to the roller 200 can be shaved off; the other side of the material-shaving plate 140 faces the discharge guide 130 so that the shaved fecal solids can fall onto the discharge guide 130 and be guided by the discharge guide 130 to the discharge outlet 120 for discharge.

As shown in FIG. 4, a water tank 700 may be further disposed at a bottom position in the housing 100, the water tank 700 is disposed at a corresponding position below the roller 200, and the roller 200 is projected downward to fall into the water tank 700. Therefore, after water separated from the excrement on the roller 200 after rolling passes through the roller 200 and drips, the water can fall into the water tank 700, so that the water after solid-liquid separation of the excrement is collected, and the pollution to the surrounding environment is avoided.

FIG. 5 is a perspective view of a roller 200 according to an embodiment of the present application; FIG. 6 is an axial cross-sectional view of the roller 200 of FIG. 5; FIG. 7 is a schematic view of the structure of the disc 220 in FIG. 5; FIG. 8 is a cross-sectional view of the disc 220B-B of FIG. 7; fig. 9 is a schematic structural view of the gap sheet 230 in fig. 6. As shown in fig. 5 to 9, the roller 200 in the embodiment of the present application includes: a shaft 210, a disc 220, and a spacer 230.

Wherein, the disc 220 is in a circular sheet shape, the discs 220 are arranged on the shaft 210 in a plurality, the discs 220 are arranged coaxially with the shaft 210, and the discs 220 are arranged at intervals along the axial direction of the shaft 210. Accordingly, the radial dimension of the clearance pieces 230 is smaller than that of the discs 220, and the clearance pieces 230 are provided in plural on the shaft 210, respectively between the adjacent discs 220. The shaft 210 is drivingly connected to the motor 300, and the disc 220 can be driven to rotate by the motor 300.

Accordingly, the excrements can be rolled by the outer circumferential surfaces of the plurality of circular disks 220. The gap sheets 230 are arranged between the discs 220, so that a gap is formed between the discs 220, water crushed from excrement can pass through the gap, and solid-liquid separation of the excrement is realized during crushing.

In addition, since the roller 200 has the circular disc 220, it can bear a larger rolling force in the radial direction of the disc 220, so that the bearing capacity of the roller 200 against the rolling force can be improved. Therefore, the grinding force for solid-liquid separation of the excrement can be improved, so that the solid-liquid separation capacity of the excrement is improved, and the solid-liquid separation effect of the excrement is improved.

Further, since the roller 200 is formed of a plurality of discs 220, when the rolling roller 400 rolls on the surface of the roller 200, the rolling force can be distributed to the respective discs 220, so that the bearing capacity of the roller 200 against the rolling force can be improved.

As shown in fig. 8, the edge of disc 220 is provided with a thickened portion 223, the thickness of thickened portion 223 on disc 220 is greater than the thickness of the portion adjacent to the inner peripheral side, specifically, the section of thickened portion 223 at the edge of disc 220 is wedge-shaped, i.e. the thickness is smaller closer to the center of disc 220. Therefore, after the plurality of discs 220 are disposed on the shaft 210, the gap between the discs 220 at the edge position is smaller than the gaps at other positions. Therefore, the feces will not be blocked between the discs 220 after passing through the gap at the edge of the discs 220, thereby preventing the roller 200 from being blocked due to long-term use.

Preferably, the distance between thickened portions 223 of adjacent discs 220 is 0.3mm or more and 1.2mm or less. Therefore, the separation of water is prevented from being influenced by too small intervals, or the solid-liquid separation effect is prevented from being influenced by excessive excrement passing through the intervals due to too large intervals.

Preferably, the disc 200 and/or the gap sheet 230 may be made of stainless steel, thereby improving the corrosion resistance of the disc 200 and/or the gap sheet 230 and increasing the lifespan of the roller 200.

As shown in fig. 7 and 8, a first mounting hole 221 is formed at an axial position of the disc 220, the first mounting hole 221 is adapted to the shaft 210, for example, the shaft 210 shown in fig. 5 and 7 may be cylindrical, the first mounting hole 221 is a circular through hole, and a key groove is formed at a position of the shaft 210 corresponding to the first mounting hole 221, so that the disc 220 may be fixed to the shaft 210 after passing through the first mounting hole 221 and being mounted on the shaft 210. Meanwhile, the roller 200 can be conveniently disassembled and assembled, and after the local position of the roller 200 is damaged, only the damaged disc 220 can be replaced without overall replacement. Therefore, the maintenance difficulty can be reduced, and the maintenance cost is saved.

As shown in fig. 5 and 7, a second mounting hole 222 is further formed on the disc 220 in a region between the edge of the disc 220 and the first mounting hole 221, and the second mounting hole 222 may have a fan shape or other suitable shape. The second mounting holes 222 may be provided in plural as shown in fig. 7, and the plural second mounting holes 222 may be arranged in a circular array with the axis of the shaft 210 as a center. After the disks 220 are inserted into the shaft 210, the disks 220 and the shaft 210 can be positioned by keys arranged in the key slots, so that the corresponding second mounting holes 222 between different disks 220 are overlapped in the axial direction to form a mounting space for mounting a drainage channel 240.

As shown in fig. 5, the roller 200 of the embodiment of the present application further includes a drainage groove 240, the drainage groove 240 may be a through-groove-shaped member formed by bending a plate member, and is disposed in the mounting space formed by the corresponding second mounting holes 222 of the plurality of discs 220 along the axial direction of the shaft 210, and the notch of the drainage groove 240 is disposed opposite to the shaft 210, that is, the notch of the drainage groove 240 is disposed outward along the radial direction of the discs 220. Therefore, when the water after solid-liquid separation is generated by rolling the feces on the upper part of the roller 200 and falls from the gap between the discs 220, the water can be collected by the drainage grooves 240 and discharged from the two ends of the drainage grooves 240 under the guidance of the drainage grooves 240, thereby avoiding the gap blockage caused by long-term use of the roller 200.

As shown in fig. 5, a plurality of drainage grooves 240 corresponding to the second mounting holes 222 may be correspondingly formed, and when the roller surface of the roller 200 rotates to the rolling position at different positions, the drainage grooves 240 may guide and drain separated water, thereby preventing blockage due to long-term use.

As shown in fig. 6 and 9, a third mounting hole 231 is disposed at the axial center of the gap piece 230, and the third mounting hole 231 is adapted to the shaft 210, so that the gap piece 230 can pass through the third mounting hole 231 and be mounted on the shaft 210. Specifically, the gap sheet 230 is disposed between two adjacent discs 220, and the thickness of the gap sheet 230 is set such that, after the two side surfaces of the gap sheet 230 are respectively abutted against the two adjacent discs 220, the two adjacent discs 220 are separated from each other in the region except for the abutment against the gap sheet 230, so that the water after solid-liquid separation is conveniently separated from the solid excrement through the gap between the discs 220. Meanwhile, the maintenance difficulty can be reduced, and the maintenance cost is saved.
