Description

Technical Field

[0001] The invention relates to the field of garbage processing equipment, and in particular to a vertical slurry-solid-slag separation system. Background Art

[0002] Domestic food waste has a complex composition, with a mixed solid-liquid state of organic and inorganic substances. It includes soft organic waste such as various vegetables and fruits, as well as hard inorganic substances such as iron spoons, wooden chopsticks, porcelain / glass / plastic tableware. It is technically difficult to separate organic and inorganic substances. Therefore, how to completely extract organic matter from food waste, avoid organic waste, and completely remove inorganic matter is a global problem that has long plagued the food waste treatment industry.

[0003] In the food waste treatment industry, the key indicators for measuring the pretreatment effect are the utilization rate of organic matter and the separation rate of inorganic impurities. In the existing food waste pulping system, the separation of organic matter and inorganic matter in the process is mostly done by filtering and separation after pulping. Common pulping machines often mix and crush the garbage and then pulp it through water washing to separate light soluble organic matter from inorganic matter.

[0004] Among them, when the garbage is crushed, the degree of crushing of the garbage has a greater impact on the separation effect, that is, the greater the degree of crushing of the garbage, the better the separation effect. When ensuring a high degree of crushing of the garbage, the highly rotating blades of the crushing equipment are severely worn, the pulping effect is poor, and the equipment operation is unstable. Based on the above background, the applicant conducted research on a slurry separation device that can fully separate mixed garbage with a low degree of crushing. The study found that in the crushing process, organic matter is more likely to be crushed to a small particle size first, and inorganic matter with a hard texture and high density (stone, glass or ceramics, etc.) is easy to separate from the combined organic matter. Further crushing can further crush the light inorganic matter into small particles to facilitate the separation of light inorganic matter and combined organic matter, thereby improving the separation efficiency.

[0005] Based on the above background research, the applicant proposed a separation solution for mixed garbage with a low degree of crushing. At present, there is a device such as a turbine water sedimentation separator for inorganic materials of domestic garbage disclosed in application number 201620251959.7, which can promote the separation of sediment in floating objects by rotating the propeller. In this way, small-particle inorganic and organic matter in the floating objects need to be separated again, and large-particle inorganic floating objects in the barrel need to be taken out separately. The applicant proposed a vertical slurry-solid slag separation system to improve the separation efficiency of garbage. Summary of the invention

[0030] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0031] In the present invention, if Figures 1 to 5 As shown, a vertical slurry-solid separation system is provided, comprising: a silo 1, wherein the silo 1 has an inner cavity, and the side wall of the silo 1 is provided with an overflow port; a separation barrel 2 assembly, wherein the separation barrel assembly comprises a separation barrel 2 vertically arranged in the silo 1, a slag discharge auger 3 connected to the bottom of the separation barrel 2, a feed pipe 4 connected to the separation barrel 2 at the upper part of the slag discharge auger 3, and a lifting screw 5 arranged in the separation barrel 2, filter holes 6 are provided on the surface side of the separation barrel 2, and a discharge port 7 is provided on the upper section of the separation barrel 2; wherein the overflow port is not higher than the upper edge of the connection part between the feed pipe 4 and the separation barrel 2.

[0032] When the separation system of the present invention is in use, water is supplied to the separation cylinder 2 through the water inlet pipe 9, and the liquid level in the silo 1 is controlled through the overflow port, so that the liquid level in the separation cylinder 2 is higher than that in the silo 1. The organic debris carried by water in the separation cylinder 2 is discharged outwardly through the filter hole 6 under the action of the liquid pressure difference in the separation cylinder 2 and the stirring promotion of the lifting screw 5, and the organic debris in the silo 1 is discharged from the overflow port. After the initially crushed garbage is put into the separation cylinder 2 through the feed pipe 4, the inorganic and organic substances of the light substances gradually float up and are further separated under the stirring driven by the lifting screw 5, and the inorganic solid slag gradually moves downward to the bottom of the separation cylinder 2. After the inorganic solid slag at the bottom of the separation cylinder 2 is deposited for a certain period of time, it is discharged outwardly through the slag discharge auger 3.

[0033] The slurry solid residue separation system of the present invention can complete the separation of inorganic solid residue, organic slurry and inorganic floating matter at one time, and simplifies the sorting process compared with the existing sorting machine. More importantly, the present invention uses the lifting screw 5 and the buoyancy of water in the separation cylinder 2, and the light inorganic matter with a lower degree of crushing is washed, stirred and squeezed during the floating process, which promotes the separation of organic matter combined with light inorganic matter, so that the organic matter can be discharged from the filter hole 6, and the water inlet pipe 9 arranged at the top of the filter cylinder can further wash the inorganic matter combined with the organic matter lifted to the non-immersed area in a leaching manner, thereby improving the efficiency of separating light inorganic matter from organic matter. Moreover, with the vertically arranged separation cylinder 2, under the combination of water buoyancy and the lifting screw 5, light inorganic matter with a lower degree of crushing is more likely to float upward, thereby reducing the possibility of light inorganic matter with a lower degree of crushing adhering and clogging in the separation cylinder 2.

[0034] In a preferred embodiment, the further optimized setting of the present invention is that the lifting screw 5 includes a screw body and a stirring rod 8 arranged at the lower side of the screw body, the upper edge of the stirring rod 8 extends to the position where the separation cylinder 2 is connected to the feed pipe 4, and the lower edge extends to the lower side of the position where the feed pipe 4 is connected to the separation cylinder 2. As shown in the figure, the lower end of the screw body is arranged on the upper side of the feed port, so that after the garbage enters the separation cylinder 2, it is first stirred by the stirring rod 8 to promote the dispersion of the garbage, so as to promote the downward precipitation of inorganic matter with higher density, and the floating speed of light inorganic matter at the position where the feed pipe 4 enters is reduced compared with the direct spiral driving method of the lifting screw 5, and the stirring can be used to further promote the separation of organic matter combined with light inorganic matter.

[0035] In a preferred embodiment, a further optimized setting of the present invention is that the gap between the outer edge of the lifting screw 5 and the inner surface of the separation cylinder 2 is greater than or equal to 1 cm and less than or equal to 3 cm.

[0036] As shown in the figure, the largest area of ​​the outer edge of the lifting spiral 5 is located at the spiral body. By controlling the gap between the outer surface of the lifting spiral 5 and the inner surface of the separation cylinder 2, it can not only promote the high-density inorganic matter being carried upward to move to the edge of the lifting spiral 5 under the action of centrifugal force and then move downward, but also promote the water flowing down from above to flow downward quickly, and promote the water carrying organic matter to flow out from the filter hole 6.

[0037] In a preferred embodiment, the present invention is further optimized in that the separation cylinder 2 is coaxially provided with an inner cylinder 10 on the inner side of the upper part of the feed pipe 4 in the bin body, the inner cylinder 10 is evenly distributed with through holes 17, the inner cylinder 10 is connected to the lifting screw 5, and the aperture of the filter hole 6 of the separation cylinder 2 at the position corresponding to the inner cylinder 10 is larger than the aperture of the through hole 17.

[0038] As shown in the figure, the evenly distributed through holes 17 of the inner cylinder 10 can be actually used as filter holes 6, and the filter holes 6 of the separation cylinder 2 in the inner cylinder 10 area become larger to increase the permeability. The relative rotation of the inner cylinder 10 and the separation cylinder 2 can promote the flow fluctuation of the liquid in the through holes 17 of the inner cylinder 10 to prevent the through holes 17 from being blocked. At the same time, the filter holes 6 can be intermittently connected with the through holes 17 to drain water, further promote the pressure fluctuation of the liquid inside the inner cylinder 10, and further promote the flow of water and the separation of organic and inorganic substances in the inner cylinder 10.

[0039] In a preferred embodiment, the present invention is further optimized in that the lifting screw 5 forms a material-shifting section on the inner side of the inner tube 10; the material-shifting section includes a shaft 11, a material-shifting rod 12 arranged on the shaft 11, and / or a material-shifting plate.

[0040] As shown in the figure, by setting a material-diverting section inside the inner cylinder 10, the light organic matter and inorganic matter can be driven to rotate by the stirring rod 8 during the upward floating process inside the inner cylinder 10, so as to further promote the separation of light organic matter and inorganic matter, and at the same time, the centrifugal force driven by the stirring of the material-diverting plate or the material-diverting rod 12 is used to promote the water to drive the light organic matter to be discharged from the filter hole 6. Compared with the lifting screw 5 driving the material diverting method, the material diverting method using the material-diverting section can also slow down the floating speed of light organic matter and inorganic matter, so as to further improve the thoroughness of separation.

[0041] In the illustrated embodiment, the stirring rod 8 is connected to the lower side of the material diverting section, which is not a limitation of the present invention. In an optional embodiment, the lifting screw 5 can also be directly extended to the stirring rod 8, and the lifting screw 5 is directly connected to the stirring rod 8.

[0042] In a preferred embodiment, a further optimized configuration of the present invention is that a cleaning brush 13 is provided on the inner side of the separation cylinder 2 corresponding to the position of the inner cylinder 10. As shown in the figure, a cleaning brush 13 is provided in the area outside the through hole 17 of the separation cylinder 2 corresponding to the inner cylinder 10, so that the through hole 17 can be further cleaned when the inner cylinder 10 rotates, so as to further maintain the passability of the through hole 17.

[0043] Specifically, as shown in the figure, the filter holes at the position of the separation cylinder corresponding to the inner cylinder are arc-shaped, and multiple through holes 17 in the circumferential direction can be connected to the filter holes 6 at the position of a separation cylinder 2 at the same time. A cleaning brush 13 is provided in the part of the separation cylinder 2 between the filter holes 6, so as to maintain the unobstructed discharge of the through holes 17 on the inner cylinder 10 and ensure the cleaning effect of the cleaning brush 13.

[0044] In a preferred embodiment, for the structure of the present invention, to be further specific, the stirring rod 8 includes a rod body 801 and a plate body 802 spirally arranged on the rod body 801, the plate body 802 is arranged to be spiral relative to the rod body 801, and the rotation direction of the plate body 802 is opposite to that of the lifting spiral 5.

[0045] By setting the stirring rod 8 with a spiral plate 802, the garbage located between the lifting spiral 5 and the plate 802 can be pushed downward by the plate 802, which can drive some light garbage to move downward first, thereby promoting the time for the light garbage to be stirred and separated from the combined organic matter and high-density inorganic matter, so as to further improve the efficiency of separation of organic and inorganic matter.

[0046] Specifically, in the illustrated embodiment, the stirring rod 8 extends into the feeding position of the feeding pipe 4, so that the material entering the separation cylinder 2 has a tendency to be pushed downward after being dispersed by the plate 802. In this way, when the garbage is pushed downward and dispersed, the separation of high-density inorganic matter and the combined organic matter can be promoted to prevent the high-density inorganic matter from being carried up by the organic matter and being driven up by the water flow stirred by the lifting screw 5, thereby promoting the rapid sinking of the high-density inorganic matter. At the same time, the residence time of the light inorganic matter in the stirring rod 8 area is increased to further improve the separation effect between the light organic matter and the light inorganic matter.

[0047] In a preferred embodiment, for the structure of the present invention, more specifically, the radial dimension of the outer edge of the plate 802 is smaller than the radial dimension of the outer edge of the lifting screw 5. As shown in the figure, by such an arrangement, it is convenient for light inorganic matter and light organic matter to float upward.

[0048] In a preferred embodiment, for the structure of the present invention, more specifically, there is a gap between the projections of the adjacent plates 802 in the vertical direction. As shown in the figure, by such an arrangement, it is convenient for light inorganic matter and light organic matter to float upward.

[0049] In a preferred embodiment, a further optimized configuration for the structure of the present invention is that a feeding screw is provided in the feeding pipe 4 .

[0050] Alternatively, the feed pipe 4 may be directly arranged to be inclined or vertical, and the garbage may fall into the separation cylinder 2 .

[0051] In the illustrated embodiment, a further optimized configuration of the present invention is that the overflow port is connected to an overflow pipe 14 , and a slag discharge pipe 15 communicating with the bin body 1 is provided at the lower side of the overflow port, and the slag discharge pipe 15 is provided with a regulating valve 16 .

[0052] As shown in the figure, a part of the light waste in the middle and lower layers of the bin body can be discharged outwards through the slag discharge pipe 15 arranged at the lower side of the overflow port. The slag discharge flow rate of the slag discharge pipe 15 is adjusted by the regulating valve 16 to control the discharge speed of the liquid in the middle and lower layers of the bin body.

[0053] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0054] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
