Description

Technical Field

[0001] This utility model relates to the field of material separation technology, and in particular to a device for separating biomass residue and charcoal powder. Background Technology

[0002] Charcoal powder is made from agricultural crop straw and forestry residues, and is used in metallurgy, pharmaceuticals, and formaldehyde adsorption. Household waste containing components such as straw, sawdust, fruit shells, sand, and non-metallic materials can be pyrolyzed and carbonized to obtain charcoal powder, but this charcoal powder contains impurities such as sand, non-metallic materials, and biomass residues.

[0003] In existing technologies, the separation of charcoal powder and impurities such as biomass residue often results in either dust generation or interruption of the charcoal powder separation process due to abnormal pressure within the separation chamber, making it difficult to continuously feed and separate charcoal powder containing biomass residue and other impurities. For example, the charcoal powder separation device containing sand disclosed in patent document CN204841909U includes a shaking table, a feeding device including a hopper located above the shaking table, and a driving device that drives the shaking table to reciprocate longitudinally to cooperate with a water supply device to wash the material. However, during the process of the charcoal powder containing sand entering the shaking table from the hopper, the charcoal powder and gravel are easily carried away by the air, generating dust. A separation device for ash particles and charcoal particles in power plant fly ash disclosed in patent document CN107252734A includes a hopper arranged from top to bottom and a primary separation device. During the process of the fly ash in the hopper entering the primary separation device, it is easily carried away by the air, generating dust. Furthermore, when the devices in patent documents CN204841909U and CN107252734A are used to separate materials containing biomass residue after pyrolysis and carbonization, the separation of carbon powder is easily interrupted due to abnormal pressure in the shaking table or primary separation device.

[0004] Therefore, how to improve the continuity of separation of impurities such as charcoal powder and biomass residue while reducing dust generation during the separation process has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a separation device for biomass residue and charcoal powder, so as to improve the continuity of separation of impurities such as charcoal powder and biomass residue while reducing dust during the separation process.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a separation device for biomass residue and charcoal powder. The separation device includes a separation box, a cavity inside the separation box, an inlet, an exhaust port, and a first outlet communicating with the cavity on the separation box, and a separation unit inside the cavity. The cavity is filled with water; the feed inlet is used to add materials to the cavity, the materials including biomass residue and charcoal powder, the density of the biomass residue being greater than the density of the charcoal powder; the feed inlet is provided with several first water sprayers connected to a water source, the first water sprayers being arranged towards the material feeding path, and the water sprayed by the first water sprayers intersecting the material feeding path; the first discharge outlet is used to discharge charcoal water, and the first discharge outlet is higher than the initial water level in the cavity; The separation unit includes a separation component rotatably disposed within the cavity, and a first driving component that is drively connected to the separation component. The first driving component is used to drive the separation component to rotate, and the separation component is in contact with the water filling the cavity.

[0007] Preferably, the first water spray component includes a plurality of annular water pipes spaced apart from top to bottom at the feed inlet, the annular water pipes being connected to a water source, and a plurality of water spray holes connected to the annular water pipes being provided along the circumference of the annular water pipes, the water spray holes being arranged toward the material feeding path; and / or, a plurality of nozzles connected to the water source and arranged toward the material feeding path are provided at the feed inlet.

[0008] Preferably, all the spray holes on the same annular water pipe are arranged opposite each other, or the spray holes are arranged facing downwards from the feed inlet.

[0009] Preferably, the exhaust vent is provided with a plurality of second water sprayers connected to a water source, the second water sprayers are arranged toward the gas exhaust path, and the water sprayed by the second water sprayers intersects with the gas exhaust path.

[0010] Preferably, the separation box is provided with a second discharge port communicating with the cavity, and the separation device further includes a discharge assembly, which includes a spiral blade rotatably disposed in the cavity, and a second driving member connected to the spiral blade for driving the spiral blade to rotate, and applying a first force toward the second discharge port to the biomass residue through the spiral blade, wherein at least one end of the spiral blade is located at the bottom of the cavity.

[0011] Preferably, the spiral blades extend from one end of the cavity toward the feed inlet toward the other end of the second discharge outlet.

[0012] Preferably, the rotation axis of the spiral blade is inclined to the separation box, and the end of the spiral blade near the second discharge port is higher than the end of the spiral blade away from the second discharge port.

[0013] Preferably, the rotation axes of the helical blades and the separator are inclined.

[0014] Preferably, the separation device further includes a third water spray component disposed toward the spiral blade, the third water spray component being connected to a water source, and the water sprayed by the third water spray component intersecting the rotation trajectory of the spiral blade.

[0015] Preferably, the separation device further includes a first level gauge and a second level gauge disposed on the separation tank and communicating with the cavity. The first level gauge is disposed at the lowest water level of the separation tank, and the second level gauge is disposed at the highest water level of the separation tank. The highest water level is not lower than the first discharge port. Alternatively, the separation device may include an observation window on the separation tank, the observation window being independently set from the water inside the cavity, and the observation window being used by the user to observe the water level inside the separation tank.

[0016] The present invention achieves the following technical advantages over the prior art: The separation device of this invention includes a separation box with a cavity inside. The separation box has an inlet communicating with the cavity, and the cavity is filled with water. The inlet is used to add materials to the cavity, including biomass residue, sand, non-metallic impurities, and carbon powder. Several first water sprayers connected to a water source are located at the inlet. These first water sprayers are positioned towards the material's feeding path and spray water onto it. The water sprayed by the first water sprayers intersects with the material's feeding path, allowing the material to absorb water before contacting the water in the cavity. The water molecules neutralize the carbon powder from the feed. The partial charge generated by friction during the process of the charcoal powder falling into the water in the cavity reduces the charge generated by the continuous friction of the charcoal powder falling into the water in the cavity from the feed inlet. Under the influence of the charge, the charcoal powder particles, along with impurities such as biomass residue, "clump together" (impurities refer to components in the material other than charcoal powder), making it difficult to separate the charcoal powder and impurities. This keeps the charcoal powder and impurities in a more dispersed state, which is conducive to subsequent separation. At the same time, after the first water spray component wets the material, the charcoal powder and other material particles settle and fall into the water in the cavity, thereby reducing the dust generated during the material feeding process. Furthermore, the cavity is equipped with a separation unit, which includes a separator rotatably disposed within the cavity and a first drive unit connected to the separator. The first drive unit drives the separator to rotate. The separator is in contact with the water within the cavity. When material falls into the water within the cavity, the first drive unit drives the separator to rotate, causing it to collide with the material and break up the clumps formed by the softening of fibers in the biomass residue upon contact with water, making them more "adhesive" and adsorbed onto the charcoal powder. This reduces the clumping of charcoal powder and biomass residue, accelerating their separation. After being broken up by the separator, the charcoal powder floats to the top of the water because the density of charcoal powder is higher than that of water, while the density of impurities such as biomass residue is higher than that of water. The biomass residue and other impurities sink to the bottom. Underwater, the separation of charcoal powder and biomass residue and other impurities is achieved within the chamber. Furthermore, the separation chamber has a first discharge port connected to the chamber. The initial water level within the chamber is lower than the first discharge port, which prolongs the separation time of the material within the chamber and reduces the possibility of the mixture of charcoal powder and biomass residue and other impurities being discharged with the water before separation, thus preventing separation failure. As material continuously enters, the first water spray component continuously sprays water into the chamber, causing the water level to rise until it reaches the first discharge port. At this point, the mixture of charcoal powder and water above the biomass residue and other impurities (referred to as charcoal water) is discharged through the first discharge port, thus achieving the separation of charcoal powder and biomass residue and other impurities. Furthermore, the separation box is equipped with an exhaust vent connected to the cavity, which allows gases such as nitrogen that enter the cavity with charcoal powder and biomass residue to be discharged from the exhaust vent (domestic waste containing components such as straw, wood chips, fruit shells, sand, gravel, and non-metallic materials is introduced with gases such as nitrogen during the pyrolysis and carbonization process to create an inert gas atmosphere, so charcoal powder mixed with biomass residue will contain gases such as nitrogen). This ensures that the pressure inside the cavity is balanced under continuous feeding conditions, reducing the problem that the pressure inside the cavity is greater than the external pressure due to the lack of an exhaust vent, which would prevent the continuous feeding of charcoal powder mixed with biomass residue and cause the charcoal powder separation to be interrupted. This improves the continuity of the separation of charcoal powder and impurities such as biomass residue. As can be seen from the above, the separation device in this utility model improves the continuity of separation of impurities such as carbon powder and biomass residue while reducing dust generation during the separation process.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-2 As shown, this utility model discloses a separation device for biomass residue and charcoal powder. The separation device includes a separation box 1, which has a cavity. The separation box 1 has a feed inlet 2 communicating with the cavity. The cavity is filled with water. The feed inlet 2 is used to add materials into the cavity, including biomass residue, sand, non-metallic impurities, and charcoal powder. Several first water sprayers 3 communicating with a water source are provided at the feed inlet 2. The first water sprayers 3 are arranged towards the material feeding path and are used to spray water onto the material feeding path. The water sprayed by the first water sprayers 3 intersects with the material feeding path, which allows the material to be pre-treated before contacting the water in the cavity. The water absorption neutralizes some of the charge generated by friction during the process of the charcoal powder falling from the inlet 2 into the water in the cavity. This reduces the charge generated by the continuous friction during the process, causing the charcoal powder particles to clump together with impurities such as biomass residue under the influence of the charge (impurities refer to components other than charcoal powder in the material). This makes it difficult to separate the charcoal powder and impurities, resulting in a more dispersed state for subsequent separation. At the same time, after the first water spray component 3 wets the material, the charcoal powder and other material particles settle and fall into the water in the cavity, thereby reducing the dust generated during the material feeding process. Furthermore, the cavity is equipped with a separation unit, which includes a separator 4 rotatably disposed within the cavity and a first drive 7 connected to the separator 4. The first drive 7 drives the separator 4 to rotate. The separator 4 is in contact with the water within the cavity. When material falls into the water within the cavity, the first drive 7 drives the separator 4 to rotate. The separator 4 collides with the material and breaks up the clumps formed by the softening of fibers in the biomass residue upon contact with water, making them more "adhesive" and adsorbed onto the carbon powder. This reduces the clumping of carbon powder and biomass residue, accelerating their separation. After being broken up by the separator 4, the carbon powder floats on top of the water because the density of carbon powder is higher than that of water, while the density of impurities such as biomass residue is higher than that of water. Submerged underwater, the material is separated from impurities such as charcoal powder and biomass residue within the chamber. Furthermore, the separation chamber 1 has a first discharge port 5 connected to the chamber. The initial water level inside the chamber is lower than the first discharge port 5, which prolongs the separation time within the chamber and reduces the likelihood of the mixture of charcoal powder and biomass residue being discharged with the water before separation, thus preventing separation failure. As material continuously enters, the first water sprayer 3 continuously sprays water into the chamber, causing the water level to rise until it reaches the first discharge port 5. At this point, the mixture of charcoal powder and water above the biomass residue (referred to as charcoal water) is discharged through the first discharge port 5, thus achieving the separation of charcoal powder and biomass residue. Furthermore, the separation chamber 1 is equipped with an exhaust vent 6 that communicates with the cavity. This allows gases such as nitrogen that enter the cavity along with charcoal powder and biomass residue to be discharged through the exhaust vent 6 (domestic waste containing components such as straw, sawdust, fruit shells, sand, gravel, and non-metallic materials is introduced with gases such as nitrogen during the pyrolysis and carbonization process to create an inert gas atmosphere, so charcoal powder mixed with biomass residue will contain gases such as nitrogen). This ensures the pressure balance within the cavity under continuous feeding conditions, reducing the problem of charcoal powder separation interruption caused by the lack of an exhaust vent 6, where the pressure inside the cavity is greater than the external pressure, preventing the continuous feeding of charcoal powder mixed with biomass residue into the feed inlet 2. This improves the continuity of charcoal powder and biomass residue separation. As can be seen from the above, the separation device in this utility model improves the continuity of charcoal powder and biomass residue separation while reducing dust generation during the separation process.

[0022] The separation chamber 1 can be configured in various shapes, such as cuboid or cylindrical, depending on the operating requirements. The chamber can also be filled with other liquids that facilitate the separation of biomass residues and other impurities from charcoal powder, and which do not react with the charcoal powder (separation means that the biomass residues and other impurities are located at the bottom of the liquid filling the chamber, and the charcoal powder is located at the top), such as sodium chloride aqueous solution or ethylene glycol aqueous solution. Materials can be added either by conveying the pyrolysis and carbonization raw materials to the feed inlet 2 via a belt conveyor or other conveying equipment, or, when the pyrolysis and carbonization device is located above the separation chamber 1, the discharge port of the pyrolysis and carbonization device can be directly connected to the feed inlet 2 of the separation chamber 1, allowing the material to slide into the feed inlet 2 under its own weight.

[0023] like Figures 1-2 As shown, the separator 4 includes a first rotating shaft 10, with separation chambers 1 extending from both ends of the first rotating shaft 10. One end of the first rotating shaft 10 is connected to the output end of the first driving component 7, and the other end of the first rotating shaft 10 is rotatably connected to a bearing in the support 8. Specifically, the separator 4 may consist of several blades 16 fixed on the first rotating shaft 10, and the blades 16 may be spiral or flat. The first driving component 7 may be a rotary drive device such as a rotary motor that can drive the separator 4 to rotate. Contact between the separator 4 and the water phase filling the chamber means that the rotation trajectory of the separator 4 is at least tangent to the lowest water level in the chamber, ensuring that the separator 4 can contact the material falling on the liquid surface of the chamber during rotation, breaking up clumps of impurities such as carbon powder and biomass residue. Depending on the operating conditions, the separator 4 may be completely below the liquid surface, or a portion of the separator 4, i.e., some blades, may be below the liquid surface. The separator 4 is rotatably disposed within the cavity, meaning there is a gap between the separator 4 and the inner wall of the separation chamber 1. The separator 4 can rotate under the action of the first driving member 7. Furthermore, the separator 4 can also be disposed directly below the feed inlet 2. Compared to the method where the separator 4 is not disposed directly below the feed inlet 2, and the material needs to flow a certain distance after reaching the liquid surface in the cavity before contacting the separator 4, this allows the carbon powder mixed with impurities such as biomass residue to contact the separator 4 more quickly and be separated, thus improving the separation efficiency of carbon powder and impurities such as biomass residue.

[0024] like Figure 1 As shown, several second water sprayers 12 connected to a water source and facing the gas discharge path are provided at the exhaust vent 6. The water sprayed by the second water sprayers 12 intersects with the gas discharge path, which makes the nitrogen and other gases wetted by water when they are discharged from the exhaust vent 6. This causes carbon powder and other particles with a density greater than nitrogen to settle, thereby reducing the amount of carbon powder discharged with the nitrogen. This not only reduces the dust phenomenon at the exhaust vent 6, but also allows the carbon powder to remain in the cavity so that it can be discharged after the water level in the cavity reaches the first discharge port 5. This achieves centralized collection of carbon powder and reduces the waste caused by carbon powder being discharged with nitrogen.

[0025] like Figure 1 As shown, the separation chamber 1 is provided with a second discharge port communicating with the cavity. The separation device also includes a discharge assembly, which includes a spiral blade 9 rotatably disposed in the cavity, and a second driving member 11 that is drively connected to the spiral blade 9 and can drive the spiral blade 9 to rotate. At least one end of the spiral blade 9 is located at the bottom of the cavity, and when the second driving member 11 drives the spiral blade 9 to rotate, the spiral blade 9 can apply a first force toward the second discharge port to impurities such as biomass residue. That is, the rotation of the spiral blade 9 drives the biomass residue and other impurities settled at the bottom of the cavity to move toward the second discharge port. This allows the biomass residue and other impurities that have been separated from the carbon powder to be discharged from the cavity under the push of the spiral blade 9, so as to facilitate the subsequent separation of materials. Depending on the operating conditions, a second rotating shaft 15 can be set, on which a spiral blade 9 is installed. The second rotating shaft 15 is connected to the output end of the second drive component 11. In this case, the discharge assembly is equivalent to a single-shaft screw conveyor. Alternatively, the second rotating shaft 15 can be omitted and directly connected to the output end of the second drive component 11. The spiral blade 9 is driven to rotate by the second drive component 11. In this case, the discharge assembly is equivalent to a shaftless screw conveyor.

[0026] Furthermore, the spiral blade 9 extends from the end of the cavity towards the feed inlet 2 and towards the end of the second discharge outlet. The spiral blade 9 is arranged to avoid the separation member 4. For example, the end of the spiral blade 9 near the separation member 4 is located below the separation member 4. This allows the biomass residue to be directly transported by the spiral blade 9 towards the second discharge outlet after the carbon powder and biomass residue are separated by the separation member 4, thus accelerating the discharge of the biomass residue and other impurities from the cavity through the second discharge outlet. Alternatively, the end of the spiral blade 9 near the separation member 4 is located on the side of the separation member 4 near the second discharge outlet. In this case, the biomass residue that has settled underwater in the cavity flows a certain distance and is discharged from the cavity through the second discharge outlet by the spiral blade 9.

[0027] like Figure 1 As shown, the rotation axis of the spiral blade 9 is inclined to the separation box 1, and the end of the spiral blade 9 near the second discharge port is higher than the end of the spiral blade 9 away from the second discharge port. This allows some of the water in the biomass residue and other impurities to slide into the cavity along the inclined surface that matches the spiral blade 9 on the inner wall of the separation box 1 during the process of being transported by the spiral blade 9, thereby reducing the water content in the discharged biomass residue and other impurities and reducing the frequency of adding water into the cavity.

[0028] Furthermore, the rotation axes of the spiral blades 9 and the separator 4 are inclined, which allows impurities such as biomass residue to be dispersed by the separator 4 and the spiral blades 9 in two different directions. This disperses the clumps of biomass residue and carbon powder from multiple different directions, making the separation of biomass residue and carbon powder more complete and improving the separation effect.

[0029] The separation device also includes a third water spray element 13 disposed towards the spiral blade 9. The third water spray element 13 is connected to a water source, and the water sprayed by the third water spray element 13 intersects with the rotation trajectory of the spiral blade 9. This allows the water sprayed by the third water spray element 13 to come into contact with the biomass residue and other impurities during the process of the spiral blade 9 conveying biomass residue and other impurities towards the second discharge port. This separates the carbon powder that may remain in the biomass residue and other impurities from the impurities, thereby further improving the degree of separation between carbon powder and biomass residue and other impurities.

[0030] In this utility model, the first water spray component 3, the second water spray component 12, and the third water spray component 13 have the same structure but different placement positions. Specifically, the first water spray component 3 includes several annular water pipes arranged at intervals from top to bottom at the feed inlet 2. The annular water pipes are connected to a water source, such as a water storage tank, through a water inlet pipe. Several water spray holes are opened on the annular water pipes, and the water spray holes are arranged facing the material feeding path. Alternatively, the first water spray component 3 includes several nozzles at the feed inlet 2 that are connected to a water source, and the nozzles are arranged facing the material feeding path. Specifically, the spray holes are located inside the annular water pipe, and all spray holes on the same annular water pipe are arranged opposite each other, i.e., facing the center of the annular water pipe. This forms a water film or water curtain, which increases the contact area between the material and the water compared to a single water mist sprayed towards the material. This can neutralize more of the charge carried by the carbon powder and reduce the clumping of carbon powder and impurities. Alternatively, the same annular water pipe may have both spray holes facing inwards and spray holes facing downwards, i.e., towards the water in the cavity. Or, the spray holes on one annular water pipe may all be arranged opposite each other, while the spray holes on another annular water pipe may be arranged downwards. Several nozzles that are arranged opposite each other and / or downwards can be arranged at the same height along the circumference of the feed inlet 2, and / or several nozzles that are arranged opposite each other and / or downwards can be arranged in different height areas of the feed inlet 2.

[0031] The second water spray component 12 includes several annular water pipes spaced apart from top to bottom at the exhaust port 6. These annular water pipes are connected to a water source, such as a water storage tank, via inlet pipes. Several spray holes are opened on the annular water pipes, facing the gas exhaust path. Alternatively, the second water spray component 12 includes several nozzles at the exhaust port 6 connected to a water source, also facing the gas exhaust path. Specifically, the spray holes are located inside the annular water pipes, and the spray holes on the same annular water pipe are all positioned opposite each other, i.e., facing the center of the annular water pipe. This forms a water film or water curtain, which, compared to a single water mist sprayed towards the gas, increases the contact area between the gas and water, allowing more carbon powder carried in gases such as nitrogen to settle. Alternatively, the same annular water pipe may have both spray holes facing inwards and spray holes facing downwards, i.e., towards the water in the cavity. Alternatively, the spray holes on one annular water pipe may all be positioned opposite each other, while the spray holes on another annular water pipe may face downwards. Several nozzles can be arranged at the same height along the circumference of the feed inlet 2, either oppositely or downwardly, and / or several oppositely or downwardly arranged nozzles can be arranged in different height areas of the feed inlet 2.

[0032] Similarly, the third water spray component 13 includes a number of annular water pipes arranged at intervals from top to bottom near the second discharge port of the separation box 1. The annular water pipes are connected to a water source, such as a water storage tank, through a water inlet pipe. The annular water pipes are provided with a number of water spray holes, which are arranged toward the discharge path of biomass residue and other impurities. Alternatively, the second water spray component 12 includes a number of nozzles connected to a water source, which are arranged near the second discharge port of the separation box 1. The nozzles are arranged toward the discharge path of biomass residue and other impurities. Specifically, the spray holes are located inside the annular water pipe, and all spray holes on the same annular water pipe are arranged opposite each other, i.e., facing the center of the annular water pipe. This forms a water film or water curtain. Compared with a single water mist sprayed towards biomass residue and other impurities, this increases the contact area between the biomass residue and other impurities and the water, allowing more carbon powder carried in the biomass residue and other impurities to settle. Alternatively, the same annular water pipe may have both spray holes facing inwards and spray holes facing downwards, i.e., towards the water in the cavity. Or, the spray holes on one annular water pipe may all be arranged opposite each other, while the spray holes on another annular water pipe may be arranged downwards. Several nozzles that are arranged opposite each other and / or downwards can be arranged at the same height along the circumference of the feed inlet 2, and / or several nozzles that are arranged opposite each other and / or downwards can be arranged in different height areas of the feed inlet 2. For the aforementioned first water spray element 3, second water spray element 12, and third water spray element 13, when their water sources are located above the first water spray element 3, second water spray element 12, and third water spray element 13 respectively, the water source can be connected to the nozzles or annular water pipes in the first water spray element 3, second water spray element 12, and third water spray element 13 through the water inlet pipe, so that the water at the water source flows by itself to the nozzles or annular water pipes in the first water spray element 3, second water spray element 12, and third water spray element 13 under the action of gravity. At this time, The openings of the nozzles and spray holes need to be set small enough to ensure the atomization effect of the sprayed water, but not too small to ensure the spray volume; or, a water pump can be connected to the water inlet pipe that connects the water source to the nozzles or annular water pipes in the first water spray component 3, the second water spray component 12, or the third water spray component 13, so as to ensure the spray pressure and water delivery efficiency.

[0033] like Figure 1 As shown, the bottom of the separation box 1 is also provided with an air vent 14. When the separation box 1 stops working, the air vent 14 is opened to drain the water and residual substances in the separation box 1 and to clean the separation box 1. Specifically, a valve can be installed at the air vent 14 to control the opening and closing of the air vent 14.

[0034] In addition, the separation device also includes a first level gauge and a second level gauge installed on the separation tank 1 and connected to the cavity. The first level gauge is located at the lowest water level of the separation tank 1, and the second level gauge is located at the highest water level of the separation tank 1. The highest water level is not lower than the first discharge port 5. The operator can judge the water level change in the cavity by observing the changes in the first and second level gauges, and then judge whether water needs to be added or the feeding rate needs to be adjusted. The specific structure of the first and second level gauges is existing technology and will not be described in detail here. The highest water level refers to the highest water level allowed by the separation tank 1. When the liquid level exceeds the highest water level, the cavity will be filled with water and material, making it difficult to continue feeding, and the internal pressure of the separation tank 1 will be too high and easily damaged. The lowest water level refers to the minimum amount of water required to achieve the stratification of carbon powder and biomass impurities in water when the feeding rate remains constant per unit time.

[0035] Alternatively, the separation device includes an observation window on the separation tank 1, which is independently set from the water inside the chamber. The observation window is used by the user to observe the water level in the separation tank 1. Specifically, the observation window can be a glass or acrylic plate on the separation tank 1. The glass or acrylic plate has sufficient light transmittance so that the user can see the water level changes in the separation tank 1 through the glass or acrylic plate. The observation window covers both the lowest and highest water levels in the separation tank 1 so that the user can have a more comprehensive view of the water level changes in the separation tank 1.

[0036] In this document, "several" refers to at least one. "And / or" refers to text content preceding "and / or," and text content following "and / or" can exist simultaneously or individually. For example, "A and / or B" includes the existence of only A or B, as well as the simultaneous existence of A and B. This utility model discloses multiple technical solutions, but does not provide any contrary technical teachings. Any content not covered in this utility model is applicable to existing technologies.

[0037] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
