Description

Technical Field

[0001] This invention relates to the field of membrane sludge separation equipment technology, and more particularly to a membrane sludge separation equipment. Background Technology

[0002] Fan-Out Panel Level Packaging (FOPLP) is an advanced packaging technology based on a panel-level carrier. It achieves high-density interconnection, low cost, and high efficiency packaging by redistributing chips on a large panel (such as glass, metal, or polymer materials).

[0003] During the immersion etching stage, part of the film will detach. However, after the chemical solution and film layer fall off, a mixture of chemical solution and film layer residue is formed. The chemical solution remaining in the residue is corrosive and erosive, so the residue needs to be recycled and treated in a unified manner. However, workers should not be allowed to come into direct contact with the residue to avoid harming their health.

[0004] Current membrane sludge separation devices use large drum-type processing. Due to the large size of the drum, it occupies more equipment space, which may be difficult to plan and arrange, especially in plant space. Moreover, the large drum-type membrane sludge separation device rotates the membrane layer and chemical solution mixture in a reciprocating manner during operation, so as to separate the liquid in the membrane layer mixture, that is, the chemical solution, reducing the chemical solution content in the membrane layer mixture and facilitating subsequent membrane layer mixture recovery and processing.

[0005] However, the current separation method increases the consumption of electricity and other components. In addition, during continuous operation, the surface of the drum may wear or become clogged due to the accumulation of slag. Because of the large volume and surface area of ​​the drum, it is not easy to remove the drum from the equipment, which increases the cost and time of manual cleaning, especially in cases where frequent cleaning is required.

[0006] Therefore, a membrane sludge separation device is still needed to solve the above problems. Summary of the Invention

[0007] The present invention provides a membrane sludge separation device to solve the above-mentioned problems.

[0008] The objective of this invention is achieved through the following technical solution: A membrane sludge separation device includes: a feed pipe; A material separation chamber is connected to the feed pipe, and a roller separation assembly is connected inside the material separation chamber. The feed inlet of the roller separation assembly is connected to the feed pipe. The separation assembly includes an annular fixed cylinder and a spiral turbine connected inside the annular fixed cylinder. The spiral turbine rotates to input the drug residue mixture, and after the liquid is separated through the gap on the cylinder wall of the annular fixed cylinder, the separated drug residue mixture is output through the spiral turbine.

[0009] In one embodiment, the annular fixed cylinder includes a filter screen and a support member. The filter screen is annularly surrounding and covering the outside of the support member. The support member includes an annular component and a strip component. The annular component is connected to both ends of the strip component, supporting the filter screen as a cylindrical shape with openings on both sides. The edges of the spiral blades are connected to the strip component. A connecting shaft is connected at the axial position of the spiral blades. The spiral blades are connected to the output shaft of the drive assembly through the connecting shaft, and when rotated, they drive the annular fixed cylinder to rotate.

[0010] In one embodiment, the drive assembly includes a motor and an output shaft connected to the motor's main shaft. A first helical gear is connected to the output shaft near its end, and a second helical gear is connected to the side of the output shaft corresponding to the output shaft. The two ends of the output shaft are connected to the slag separation chamber via a rotatable connecting bracket.

[0011] In one embodiment, the mounting bracket includes a first connecting bracket and a second connecting bracket. The top of the first connecting bracket is connected to the top inner wall of the slag separation chamber, and the second connecting bracket is attached to the bottom of the first connecting bracket. The second connecting bracket has a U-shaped groove and a fixing member connected to the top of the U-shaped groove. The top of the fixing member is connected to the second connecting bracket by bolts, and the bottom of the fixing member is connected to the connecting shaft by the outer wall of the fixing bearing.

[0012] In one embodiment, the annular fixing cylinder further includes sleeves at both ends of the annular fixing cylinder for binding the filter screen to the outside of the support member, and the blade edge of the spiral blade is provided with a connecting groove that matches the cross-sectional shape of the strip member.

[0013] In one embodiment, a spray pipe is also included, which is connected inside the slag separation chamber and extends along the axial direction of the spiral turbine for scouring the wall of the annular fixed cylinder.

[0014] In one embodiment, flow holes are formed on the blades of the spiral turbine near the feed inlet, and the ratio of the cross-sectional area of ​​the feed inlet to the cross-sectional area of ​​the feed pipe is 1:(2-2.5).

[0015] In one embodiment, the system further includes a liquid recovery assembly, which includes a recovery pipeline and a recovery pump disposed at the bottom of the residue separation chamber. The recovery pump recovers the liquid after the residue mixture has been separated through the recovery pipeline.

[0016] In one embodiment, the device further includes a membrane residue drying assembly, which comprises two opposing screws for squeezing the drug residue mixture, and a drug solution separation tank located at the bottom of the screws and extending along the axial direction of the screws. The drug solution mixing tank has opposing inlets and outlets, and the surface of the tank has multiple drug solution guide channels. The inlet of the drug solution mixing tank is used to receive the drug solution mixture output from the outlet after being separated by the separation assembly. The drug solution separated by the screws flows out from the drug solution separation tank, and the separated membrane residue falls into the receiving hopper.

[0017] In one embodiment, the liquid separation tank includes a plurality of steel plates arranged in parallel, and the gap between two adjacent steel plates forms the liquid separation tank. From the inlet to the outlet direction of the liquid mixture, the liquid separation tank is divided into a first separation tank and a second separation tank. The gap between the steel plates in the first separation tank is larger than the gap between the steel plates in the second separation tank.

[0018] Compared with the prior art, the beneficial effects of the present invention include at least the following: After being conveyed by the feed pipe, the liquid medicine and the membrane layer in the membrane layer mixture fall down in the form of a solid-liquid mixture and enter the material-slag separation chamber. Driven by the rotation of the spiral turbine, the solid-liquid mixture is fully agitated and rotated on the wall of the annular fixed cylinder to separate the liquid medicine, reducing the liquid medicine content in the solid-liquid mixture. Moreover, the spiral turbine requires less torque to rotate continuously compared to a large-diameter drum, resulting in lower kinetic energy consumption and reducing the energy consumption and operating costs of drum-type membrane slag separation. The spiral blade type has a relatively smaller surface area and fewer parts, making cleaning, maintenance, or replacement simpler than the drum type. Attached Figure Description

[0021] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0022] The terms used to express position and direction in this invention are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0023] Reference Figure 1-6 The present invention provides a membrane sludge separation device, comprising: a feed pipe 1, a sludge separation chamber 2 connected to the feed pipe 1, a roller separation component 3 connected inside the sludge separation chamber 2, and the feed inlet 33 of the roller separation component 3 being connected to the feed pipe 1; The separation component 3 includes an annular fixed cylinder 31 and a spiral turbine 32 connected inside the annular fixed cylinder 31. The spiral turbine 32 rotates to feed the medicinal residue mixture, and after the liquid is separated through the gaps in the cylinder wall of the annular fixed cylinder 31, the separated medicinal residue mixture is driven by the spiral turbine 32 and output from the discharge port 34. Following this process, the medicinal residue mixture is continuously conveyed, and finally, after being driven by the spiral turbine 32, a large amount of liquid in the medicinal residue mixture is squeezed out. The annular fixed cylinder 31 has a small volume and diameter, requiring less torque and power to drive it. Furthermore, the spiral turbine 32 effectively reduces the adhesion and adsorption of the mixture to the cylinder wall of the annular fixed cylinder 31.

[0024] Preferably, the annular fixed cylinder 31 includes a filter screen 311 and a support member 312. The filter screen 311 is annularly arranged and covers the outside of the support member 312. The support member 312 includes an annular member 3121 and a strip member 3122. The annular member 3121 is connected to both ends of the strip member 3122, supporting the filter screen 311 into a cylindrical shape with openings on both sides. The edges of the spiral blades are connected to the strip member 3122. A connecting shaft 35 is connected at the axis of the spiral blades. The spiral blades are connected to the output shaft 42 of the drive assembly 4 through the connecting shaft 35, which drives the annular fixed cylinder 31 to rotate during rotation. The filter screen 311 covers the outside of the support member 312, and the support member 312 is a strip-shaped support member 312, which supports the shape of the filter screen 311 and prevents the filter screen 311 from deforming due to large impacts and material accumulation. While reducing the overall structural volume, the overall structural strength is improved. In addition, the filter screen and support component 312 are connected in a detachable manner. When the pores of the filter screen are blocked by filter residue, the filter screen can be removed to remove the filter residue, making it convenient for disassembly and replacement.

[0025] Preferably, the drive assembly 4 includes a motor 41 and an output shaft 42 connected to the main shaft of the motor 41. A first helical gear 43 is connected to the end of the output shaft 42, and a second helical gear 44 is connected to one side of the connecting shaft 35 corresponding to the output shaft 42. The two ends of the output shaft 42 are connected to the material separation chamber 2 via a rotatable connecting bracket 5. During operation, the axes of the output shaft 42 of the motor 41 and the connecting shaft 35 are perpendicular to each other. The motor 41 drives the connecting shaft 35 to rotate the spiral turbine 32 through the meshing of the first helical gear 43 and the second helical gear 44. The spiral turbine 32 and the connecting shaft 35 can be integrally formed during manufacturing, or they can be connected by welding or other processes.

[0026] Preferably, the mounting bracket 5 includes a first connecting bracket 51 and a second connecting bracket 52. The top of the first connecting bracket 51 is connected to the top inner wall of the slag separation chamber 2, and the second connecting bracket 52 is attached to the bottom of the first connecting bracket 51. The second connecting bracket 52 has a U-shaped groove 521 and a fixing member 522 connected to the top of the U-shaped groove 521. The top of the fixing member 522 is connected to the second connecting bracket 52 by bolts, and the bottom of the fixing member 522 is connected to the connecting shaft 35 by the outer wall of the fixing bearing. There can be two sets of mounting brackets 5, respectively arranged on both sides of the connecting shaft 35. The first connecting bracket 51 and the second connecting bracket 52 block the inlet and outlet of the slag separation chamber 2. The bottom of the first connecting bracket 51 extends vertically, and the second connecting bracket 52 is attached to the first connecting bracket 51 and can be fixed by bolts. In addition, the U-shaped groove on the second connecting bracket 52 can accommodate the outer diameter of the bearing, and the bolts of the fixing member 522 can be tightened for easy disassembly and replacement of different spiral turbines 32.

[0027] Preferably, the annular fixing cylinder 31 further includes a binding member 6 sleeved at both ends of the annular fixing cylinder 31 for binding the filter screen 311 to the outside of the support member 312. The spiral blades have connecting grooves 7 on their edges that match the cross-sectional shape of the strip member 3122. During connection, the filter screen 311 can be loosened by twisting the clamps, ultimately releasing the filter screen. A new filter screen can then be installed, and the binding member 6 is tightened on both sides of the filter screen 311 to complete the replacement, simplifying the filter screen replacement process and improving replacement efficiency.

[0028] Preferably, the system also includes a spray pipe 8, which is connected inside the material-slag separation chamber 2 and extends along the axial direction of the spiral turbine 32 for flushing the wall of the annular fixed cylinder 31. The spray pipe 8 is arranged laterally along the axial direction of the spiral turbine 32. During operation, the spray pipe 8 sprays out a chemical solution to wash the material residue on the filter screen, preventing solid membrane residue from adhering to and fixing on the filter screen 311, thus affecting subsequent membrane and chemical separation processes.

[0029] Preferably, flow holes 9 are formed on the blades of the spiral turbine 32 near the feed inlet 33, and the cross-sectional area ratio of the feed inlet 33 to the feed pipe 1 is 1:(2-2.5). Experimental verification shows that this ratio effectively prevents a surge in flow rate when a large amount of membrane residue and pharmaceutical solution mixture flows downstream, thus avoiding upward flow from the feed inlet 33. This efficiently ensures complete separation of membrane residue and pharmaceutical solution, preventing direct impact and outflow from the output port of the roller separator 3.

[0030] Preferably, the system also includes a liquid recovery assembly, which comprises a recovery pipeline and a recovery pump located at the bottom of the residue separation chamber 2. The recovery pump recovers the liquid from the residue mixture after separation via the recovery pipeline. A filter screen (311) is installed at the inlet of the recovery pipeline. The liquid filtered through the filter screen is absorbed into a storage chamber with the assistance of the recovery pump, and then sprayed onto a substrate via a spraying device. This process etches the substrate surface at predetermined locations to participate in the reaction, thereby improving resource utilization and saving resource consumption.

[0031] Reference Figure 5 and Figure 6It also includes a membrane residue drying assembly 10, which includes two opposing rotating screws 101 to squeeze the drug residue mixture, and a drug solution separation tank 102 located at the bottom of the screws 101 and extending along the axial direction of the screws 101. The drug solution mixing tank 102 has opposing inlets and outlets, and the surface of the tank has multiple drug solution guide channels 102. The inlet of the drug solution mixing tank is used to receive the drug solution mixture output from the outlet after being separated by the separation assembly. The drug solution separated by the screws 101 flows out from the drug solution separation tank 102, and the separated membrane residue falls into the receiving bin. The membrane residue drying assembly 10 is located near the separation assembly 3. The drug residue mixture separated by the separation assembly 3 falls into the membrane residue drying assembly 10 through the inlet. Under the squeezing action of two opposing screws 101, the material is mixed into a clump and wrung out, fully squeezing out the residual drug liquid between the mixture. The drug liquid flows out through the drug liquid separation tank and finally falls into the drug liquid collection tank below. Then, the remaining mixture is pushed by the screws 101 and is continued to rotate and wring dry until the drug liquid is completely removed. The material residue mixture after being separated by the roller separation assembly 3 is once again squeezed dry by the wringing rotation between the two screws 101, and the membrane residue drying assembly 10 is integrated on one side, without occupying additional space. Moreover, the staged removal of membrane residue can greatly improve the separation efficiency of membrane residue.

[0032] In one embodiment, the drug-liquid separation tank 102 includes a plurality of steel plates 104 arranged in parallel. The gaps between adjacent steel plates 104 form the drug-liquid separation tank 102. From the inlet to the outlet direction of the drug-liquid mixture, the drug-liquid separation tank 102 is divided into a first separation tank 1021 and a second separation tank 1022. The gaps between the steel plates in the first separation tank 1021 are larger than the gaps between the steel plates in the second separation tank 1022. The plurality of parallel steel plates 104 are connected by welding or other means. When the membrane sludge passes through the first separation tank 1021, the membrane sludge contains a large amount of water. When the flow rate is large, the first separation tank 1021 is sufficient to guide the drug liquid to the bottom or the outside, so that the drug liquid is fully separated. When it flows into the second separation tank 1022, the drug liquid content in the membrane sludge mixture is low. This avoids the membrane sludge from becoming powdery and falling into the recovery tank along the second separation tank 1022 due to low moisture content. The lower spacing can balance the flow of drug liquid and prevent dust from falling.

[0033] Experimental results show that the ratio of the cross-sectional area of ​​the feed inlet 33 to that of the feed pipe 1 is 1:(2-2.5). Within this range, the separation effect of the drug mixture after final output from the membrane residue separation device is better.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
