Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, and in particular discloses a resource recycling system for diamond wire cutting waste liquid. Background Art

[0002] In the diamond wire cutting process of single crystal silicon rods or polycrystalline silicon rods, the diamond wire cutting machine needs to use cutting fluid to lubricate, cool and remove attached silicon powder to the diamond wire. In the existing technology, the method of replacing the cutting fluid is to replace the entire cylinder of cutting fluid with a newly prepared cutting fluid after one loading and cutting is completed. The newly prepared cutting fluid is a mixture of water and cutting stock, and is preheated to a certain temperature and added to the cutting fluid cylinder for a new round of loading and cutting. For the polycrystalline silicon slicing process, in order to avoid a large amount of heat generated by long-term friction and causing damage to the diamond wire, it is necessary to continuously spray the cutting fluid to control heat accumulation and protect the diamond wire from loss. The previous cutting fluid recovery device directly recycles the cutting waste liquid, and the recycling efficiency is low. It is also unable to filter and collect the larger number of silicon wafer particles in the cutting waste liquid, resulting in a large amount of silicon resource waste and low recovery efficiency. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a resource recycling system for diamond wire cutting waste liquid.

[0004] To achieve the above-mentioned purpose, the utility model provides a resource recycling and reuse system for diamond wire cutting waste liquid, including a raw liquid collection box for collecting cutting waste liquid discharged from an external diamond wire cutting production line, a first filter mechanism connected to the raw liquid collection box via an external pipeline, and a second filter mechanism connected to the first filter mechanism via an external pipeline. The first filter mechanism and the second filter mechanism are both connected to a clean liquid tank via an external pipeline. The clean liquid tank is used to supply the clean liquid filtered by the first filter mechanism and / or the clean liquid filtered again by the second filter mechanism to the diamond wire cutting production line via an external pipeline. The clean liquid tank can continuously supply filtered clean liquid to the cutting production line, ensuring sufficient supply of cutting liquid during the cutting process, avoiding production interruption due to replacement of cutting liquid, and improving production efficiency. Since the cutting fluid can be recycled, energy consumption links such as preparation and heating of new cutting fluid are reduced, thereby reducing overall energy consumption.

[0005] Furthermore, by collecting and processing the cutting waste liquid discharged from the diamond wire cutting production line, the conversion of waste liquid into clean liquid is achieved, which greatly improves the utilization rate of resources and reduces the waste caused by direct discharge. The first filtering mechanism and the second filtering mechanism effectively remove silicon wafer particles and other impurities in the waste liquid, so that most of the clean cutting liquid can be recycled and reused, avoiding the loss of silicon resources and improving production efficiency. The clean liquid tank serves as the storage and supply center of the clean liquid, which can continuously provide filtered clean liquid to the cutting production line, ensuring sufficient supply of cutting liquid during the cutting process, avoiding the interruption of production due to the replacement of cutting liquid, thereby improving production efficiency and continuity.

[0006] Furthermore, the clean liquid tank is connected to the liquid distribution tank via an external pipeline, and the clean liquid tank supplies cutting clean liquid to the diamond wire cutting production line through the liquid distribution tank. The liquid distribution tank is used to distribute the raw liquid to the diamond wire cutting production line. The liquid distribution tank can accurately proportion and distribute the clean liquid from the clean liquid tank according to the specific needs of the diamond wire cutting production line. During the cutting process, various emergencies or changes in production needs may be encountered. The existence of the liquid distribution tank enables the system to respond to these changes more flexibly. By adjusting the proportion, increasing or decreasing the supply, etc., the normal operation of the cutting production line can be ensured. The liquid distribution tank can accurately control the supply and proportion of the cutting liquid, thereby reducing energy consumption and waste caused by excessive or insufficient supply, helping to reduce production costs and improve resource utilization efficiency.

[0007] Furthermore, the first filtering mechanism is connected to the second filtering mechanism via a sludge tank. The first filtering mechanism inputs the cutting clean liquid into the clean liquid tank, and the first filtering mechanism stores the cutting waste liquid that still needs to be filtered into the sludge tank to be subsequently input into the second filtering mechanism for re-filtration. The first filtering mechanism can remove most of the large particle impurities and suspended matter in the cutting waste liquid, and the waste liquid that still needs further filtration is stored in the sludge tank to be subsequently input into the second filtering mechanism for more refined filtration treatment, which can significantly improve the purification efficiency of the waste liquid and make the final cutting clean liquid purer. Through the synergistic effect of the first filtering mechanism and the second filtering mechanism, the useful components in the cutting waste liquid are recovered and utilized to the greatest extent, reducing the waste of resources.

[0008] Furthermore, the second filtering mechanism is connected to the first filtering mechanism via the raw liquid collection box. The second filtering mechanism is used to input the cutting clean liquid that meets the standards after filtration into the clean liquid tank. The second filtering mechanism inputs the cutting waste liquid that still does not meet the standards after filtration into the raw liquid collection box and re-filters it through the first filtering mechanism. After the second filtering mechanism filters the cutting waste liquid, if the cutting clean liquid does not meet the set quality standards, these substandard waste liquids will be re-input into the raw liquid collection box and filtered again through the first filtering mechanism, ensuring that only cutting clean liquid that meets the requirements can enter the clean liquid tank, thereby improving the purification quality and reliability of the entire system. Through the process of recycling and refiltration, the useful components in the cutting waste liquid that may have been regarded as waste are more fully recovered and utilized, avoiding waste of resources and realizing the maximum resource utilization of cutting waste liquid.

[0009] Furthermore, the first filtering mechanism is connected to an air storage tank, which is used to store or transport compressed air from the outside. The compressed air from the outside is transported to the first filtering mechanism via the air storage tank to enhance the filtering effect. The compressed air from the outside is transported to the first filtering mechanism via the air storage tank to form a gas-liquid mixed state with the cutting waste liquid. The mixed state helps to break the agglomeration force between the suspended particles and impurities in the waste liquid, making it easier to be captured by the filter medium, thereby improving the filtering efficiency. The bubbles and eddies generated by the compressed air during the filtering process can flush the surface of the filter medium, prevent filter cake formation and clogging, and maintain the permeability and filtering performance of the filter medium.

[0010] Furthermore, the first filtering mechanism includes a first filter element, which is a silicon carbide membrane. The silicon carbide membrane is provided with a first through hole for circulating liquid, a transition layer for retaining silicon powder, and a separation layer for recovering cutting waste liquid. The first through holes are distributed in a circular array, each first through hole is connected to the transition layer and wrapped by the transition layer, the separation layer is connected to the transition layer and wrapped outside the transition layer, the first through holes on the silicon carbide membrane are distributed in a circular array, each through hole is tightly connected to the transition layer and wrapped by it, so that when the waste liquid passes through, tiny particles such as silicon powder are effectively retained in the transition layer, thereby realizing efficient recovery of silicon powder. The circular array distribution of the first through holes helps to optimize the flow path of the waste liquid on the membrane surface, reduce flow resistance, and improve filtration efficiency.

[0011] Furthermore, the filtering method of the first filtering mechanism is dead-end rapid filtration. The cutting waste liquid of the diamond wire cutting production line flows into the first filtering mechanism, and the cutting waste liquid flows into the first through hole to form fluid pressure. Most of the silicon powder in the cutting waste liquid is adsorbed in the transition layer, and the cutting clean liquid separated by the separation layer enters the clean liquid collection box, and the separated primary cutting liquid enters the sludge tank through the first through hole.

[0012] Furthermore, the second filtering mechanism includes a rotating drum rotatably arranged on the second filtering mechanism and a filter screen for the cutting liquid that has passed through the primary filtration. The drum is provided with a plurality of second through holes for discharging the secondary cutting liquid, and the filter screen is used to cover the second through holes. The rotation of the drum enables the cutting liquid to form a dynamic filtration effect on the filter screen, which can more effectively separate the solid particles and liquid in the solid-liquid mixture. During the dynamic filtration process, the solid particles are thrown toward the filter screen and intercepted under the action of centrifugal force, while the liquid continues to flow through the pores of the filter screen. The rotation of the drum and the covering effect of the filter screen make the solid-liquid separation process more sufficient and efficient.

[0013] Furthermore, the solid-liquid separation component is a centrifugal separation mechanism, which includes a rotating drum and a filter screen for filtering the primary cutting liquid. The drum is provided with a plurality of second through holes for discharging the secondary cutting liquid, and the filter screen is used to cover the second through holes.

[0014] Furthermore, the drum is formed into a barrel-shaped structure, with a second through-hole arranged in an annular shape on the side wall of the drum. A filter is also installed on the side wall of the drum. As the drum rotates, solid and liquid substances of different masses are separated under the action of centrifugal force. The filter retains silicon powder particles, and the second through-hole is used to discharge the secondary cutting fluid after separation. During the rotation of the drum, solid particles on the surface of the filter are washed and dispersed, reducing the risk of clogging. This self-cleaning function helps maintain the permeability and filtration performance of the filter, extending its service life.

[0015] Furthermore, the cutting waste liquid discharged from the diamond wire cutting production line outside the raw liquid collection box is input into the first filtering mechanism for filtration. The cutting waste liquid often contains a certain amount of silicon powder. Through the filtering effect of the first filtering mechanism, these useful components can be separated from the waste liquid, which provides convenience for subsequent recycling and utilization. Directly discharging the cutting waste liquid not only wastes the useful resources therein, but may also cause pollution to the environment. Through filtering and recycling, resource waste can be minimized and resource recycling can be achieved.

[0016] Furthermore, the raw liquid collection box includes a first feed port, a first discharge port and an eleventh feed port. The raw liquid collection box collects the cutting waste liquid discharged from the external diamond wire cutting production line, and transports the waste liquid to the first filter mechanism through the first discharge port. The first filter mechanism includes a second feed port, a third feed port, a second discharge port and a third discharge port. The first filter mechanism performs dead-end filtration on the waste liquid, which can speed up the filtration and separation of the cutting waste liquid to obtain cutting clean liquid. The cutting clean liquid enters the clean liquid box through the third discharge port. The clean liquid box includes a fourth feed port, a fifth feed port and a fourth discharge port. The clean liquid box transports the clean liquid to the liquid distribution box through the fourth discharge port. The first filter mechanism transports the liquid that still needs to be filtered to the sludge box through the second discharge port. The sludge box includes a sixth feed port and a fifth discharge port. The sludge box transports the waste liquid to be filtered to the second filter mechanism through the fifth discharge port. The second The filtering mechanism includes a seventh feed port, an eighth feed port and a sixth discharge port. The second filtering mechanism transports the clean liquid to the clean liquid tank through the sixth discharge port. The clean liquid tank transports the filtered clean liquid to the liquid distribution box through the fourth discharge port. The liquid distribution box includes a ninth feed port and a seventh discharge port. The liquid distribution box distributes the clean liquid and transports it to the diamond wire cutting production line through the seventh discharge port. The air storage tank includes a tenth feed port and an eighth discharge port. The air storage tank transports the compressed air from the outside to the first filtering mechanism through the eighth discharge port. The first discharge port is connected to the second feed port, the third discharge port is connected to the fourth feed port, the eighth discharge port is connected to the third feed port, the second discharge port is connected to the sixth feed port, the fifth discharge port is connected to the seventh feed port, the eighth feed port is connected to the eleventh feed port, the sixth discharge port is connected to the fifth feed port, and the fourth discharge port is connected to the ninth feed port.

[0017] The beneficial effects of the present invention are as follows: through the synergistic effect of the first filter mechanism, the second filter mechanism, the liquid distribution box and the clean liquid tank, the efficient recovery and recycling of the cutting waste liquid of the diamond wire cutting production line is achieved, the resource utilization rate is significantly improved, the energy consumption links such as the preparation and heating of new cutting liquid are reduced, the overall production cost is reduced, and the environment is protected by reducing waste liquid discharge. The silicon carbide membrane of the first filter mechanism and its dead-end rapid filtration method ensure the efficient recovery of useful components such as silicon powder. The dynamic filtration effect of the second filter mechanism further improves the waste liquid purification efficiency. The precise proportioning and distribution function of the liquid distribution box enables the system to flexibly respond to changes in production demand and ensure the stable operation of the cutting production line. The gas storage tank enhances the filtering effect and further improves the filtering efficiency. The entire system forms a closed-loop waste liquid recovery and reuse system, which improves production efficiency, reduces energy consumption and reduces environmental pollution.

[0024] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0025] See also Figures 1 to 4 As shown, the utility model is a resource recycling and reuse system for diamond wire cutting waste liquid, including a raw liquid collection box 1 for collecting cutting waste liquid discharged from an external diamond wire cutting production line, a first filter mechanism 2 connected to the raw liquid collection box 1 via an external pipeline, and a second filter mechanism 5 connected to the first filter mechanism 2 via an external pipeline. The first filter mechanism 2 and the second filter mechanism 5 are both connected to a clean liquid tank 4 via an external pipeline. The clean liquid tank 4 is used to supply the clean liquid filtered by the first filter mechanism 2 and / or the clean liquid filtered again by the second filter mechanism 5 to the diamond wire cutting production line via an external pipeline. The clean liquid tank 4 can continuously supply filtered clean liquid to the cutting production line, ensuring sufficient supply of cutting liquid during the cutting process, avoiding production interruption due to replacement of cutting liquid, and improving production efficiency. Since the cutting liquid can be recycled, energy consumption links such as preparation and heating of new cutting liquid are reduced, thereby reducing overall energy consumption.

[0026] Specifically, by collecting and processing the cutting waste liquid discharged from the diamond wire cutting production line, the conversion of waste liquid into clean liquid is achieved, which greatly improves the utilization rate of resources and reduces the waste caused by direct discharge. The first filter mechanism 2 and the second filter mechanism 5 effectively remove silicon wafer particles and other impurities in the waste liquid, so that most of the clean cutting liquid can be recycled and reused, avoiding the loss of silicon resources and improving production efficiency. The clean liquid tank 4 serves as the storage and supply center of the clean liquid, which can continuously provide filtered clean liquid to the cutting production line, ensuring sufficient supply of cutting liquid during the cutting process, avoiding the interruption of production due to the replacement of cutting liquid, thereby improving production efficiency and continuity.

[0027] Specifically, the clean liquid tank 4 is connected to the liquid distribution tank 6 via an external pipeline. The clean liquid tank 4 supplies cutting clean liquid to the diamond wire cutting production line through the liquid distribution tank 6. The liquid distribution tank 6 is used to distribute the raw liquid to the diamond wire cutting production line. The liquid distribution tank 6 can accurately proportion and distribute the clean liquid from the clean liquid tank 4 according to the specific needs of the diamond wire cutting production line. During the cutting process, various emergencies or changes in production needs may be encountered. The existence of the liquid distribution tank 6 enables the system to respond to these changes more flexibly. By adjusting the proportion, increasing or decreasing the supply, etc., the normal operation of the cutting production line is ensured. The liquid distribution tank 6 can accurately control the supply and proportion of the cutting liquid, thereby reducing energy consumption and waste caused by excessive or insufficient supply, helping to reduce production costs and improve resource utilization efficiency.

[0028] Specifically, the first filtering mechanism 2 is connected to the second filtering mechanism 5 via the sludge tank 3. The first filtering mechanism 2 inputs the cutting clean liquid into the clean liquid tank 4. The first filtering mechanism 2 stores the cutting waste liquid that still needs to be filtered into the sludge tank 3 to be subsequently input into the second filtering mechanism 5 for re-filtration. The first filtering mechanism 2 can remove most of the large particle impurities and suspended matter in the cutting waste liquid. The waste liquid that still needs further filtration is stored in the sludge tank 3 to be subsequently input into the second filtering mechanism 5 for more refined filtration treatment, which can significantly improve the purification efficiency of the waste liquid and make the final cutting clean liquid purer. Through the synergistic effect of the first filtering mechanism 2 and the second filtering mechanism 5, the useful components in the cutting waste liquid are recovered and utilized to the greatest extent, reducing the waste of resources.

[0029] Specifically, the second filtering mechanism 5 is connected to the first filtering mechanism 2 via the raw liquid collecting tank 1. The second filtering mechanism 5 is used to input the cutting clean liquid that meets the standards after filtration into the clean liquid tank 4. The second filtering mechanism 5 inputs the cutting waste liquid that still does not meet the standards after filtration into the raw liquid collecting tank 1 and re-filters it through the first filtering mechanism 2. After the second filtering mechanism 5 filters the cutting waste liquid, if the cutting clean liquid does not meet the set quality standards, these substandard waste liquids will be re-input into the raw liquid collecting tank 1 and filtered again through the first filtering mechanism 2, ensuring that only cutting clean liquid that meets the requirements can enter the clean liquid tank 4, thereby improving the purification quality and reliability of the entire system. Through the process of recycling and refiltration, the useful components in the cutting waste liquid that may have been regarded as waste are more fully recovered and utilized, avoiding waste of resources and realizing the maximum resource utilization of cutting waste liquid.

[0030] Specifically, the first filter mechanism 2 is connected to an air storage tank 7, which is used to store or transport compressed air from the outside. The compressed air from the outside is transported to the first filter mechanism 2 via the air storage tank 7 to enhance the filtering effect. The compressed air from the outside is transported to the first filter mechanism 2 via the air storage tank 7 to form a gas-liquid mixed state with the cutting waste liquid. The mixed state helps to break the agglomeration force between the suspended particles and impurities in the waste liquid, making it easier to be captured by the filter medium, thereby improving the filtering efficiency.

[0031] Specifically, the first filter mechanism 2 includes a first filter element 220, which is a silicon carbide membrane. The silicon carbide membrane is provided with a first through hole 2201 for circulating liquid, a transition layer 2202 for retaining silicon powder, and a separation layer 2203 for recovering cutting waste liquid. The first through holes 2201 are distributed in a circular array, each of which is connected to the transition layer 2202 and wrapped by the transition layer 2202. The separation layer 2203 is connected to the transition layer 2202 and wrapped around the outside of the transition layer 2202. The first through holes 2201 on the silicon carbide membrane are distributed in a circular array, each of which is tightly connected to the transition layer 2202 and wrapped by it, so that when the waste liquid passes through, tiny particles such as silicon powder are effectively retained in the transition layer 2202, thereby achieving efficient recovery of silicon powder. The circular array distribution of the first through holes 2201 helps to optimize the flow path of the waste liquid on the membrane surface, reduce flow resistance, and improve filtration efficiency.

[0032] Specifically, the filtering method of the first filtering mechanism 2 is dead-end rapid filtration. The cutting waste liquid of the diamond wire cutting production line flows into the first filtering mechanism 2, and the cutting waste liquid flows into the first through hole 2201 to form fluid pressure. Most of the silicon powder in the cutting waste liquid is adsorbed in the transition layer 2202, and the cutting clean liquid separated by the separation layer 2203 enters the clean liquid collection box 4.

The rotation of the rotating drum 511 enables the cutting liquid to form a dynamic filtering effect on the filter screen 512, which can more effectively separate the solid particles and liquid in the solid-liquid mixture. During the dynamic filtration process, the solid particles are thrown toward the filter screen 512 under the action of centrifugal force and are intercepted, while the liquid continues to flow through the pores of the filter screen 512.

A filter 512 is also provided on the sidewall of the drum. As the drum 511 rotates, centrifugal force separates solid and liquid materials of varying masses. The filter 512 retains silicon powder particles, and the second through-hole 513 is used to discharge the separated secondary cutting fluid. As the drum 511 rotates, solid particles on the surface of the filter 512 are washed and dispersed, reducing the risk of clogging. This self-cleaning function helps maintain the filter's permeability and filtration performance, extending its service life.

[0036] Specifically, the cutting waste liquid discharged from the external diamond wire cutting production line in the raw liquid collection box 1 is input into the first filtering mechanism 2 for filtration. The cutting waste liquid often contains a certain amount of silicon powder. Through the filtering effect of the first filtering mechanism, these useful components can be separated from the waste liquid, which provides convenience for subsequent recycling.
