Abstract

This invention relates to the field of water pollution treatment technology, specifically to a wastewater recycling treatment device for masterbatch production. The device includes a water pollution treatment tank, a mounting frame fixed to the top of the tank, and a microbial agent tank fixed to the outside of one side of the tank. A cylinder is longitudinally fixed to the outside of one side of the mounting frame. The mechanical thrust of a push pin directly acts on the blockages in the nozzle micro-orifices and flow channels. The diameter of the push pin precisely matches the size of the nozzle micro-orifices, allowing it to penetrate narrow flow channels that are difficult for traditional tools to reach. Through axial movement, it breaks up and removes solid or semi-solid blockages, solving the problem of blind spots caused by complex structures. Compared to traditional manual disassembly and cleaning methods, push pin cleaning does not require stopping the machine to disassemble the nozzle. The cleaning program can be triggered periodically during equipment operation, reducing the single cleaning time from several hours to several minutes, improving cleaning efficiency, and ensuring the treatment effect of subsequent microbial agent spraying for water pollution treatment.

Description

Technical Field

[0001] This invention relates to the field of water pollution treatment technology, specifically to a wastewater recycling treatment device for color masterbatch production. Background Technology

[0002] The production of color masterbatch generates a large amount of wastewater with complex composition. This wastewater usually contains pollutants such as pigments, resins and various additives. Its complex composition poses a great challenge to wastewater treatment, and traditional treatment methods are difficult to deal with effectively. Direct discharge will cause water pollution.

[0003] Treatment methods characterized by microorganisms have emerged. The principle is to use the metabolic activities of microorganisms to degrade pollutants. This method can effectively reduce the concentration of pollutants in wastewater by virtue of the specific decomposition ability of microorganisms for different pollutants, thereby purifying the water quality. It also has advantages such as low cost and minimal secondary pollution, and shows broad application prospects in the field of wastewater treatment.

[0004] However, existing wastewater recycling treatment devices for masterbatch production on the market have revealed a series of critical problems that urgently need to be solved during actual operation. Regarding the spray nozzles in the microbial network, as usage time accumulates, the pigment particles in the wastewater vary in size. Some fine particles, carried by the water flow, enter the nozzle and easily adhere to the inner wall and flow channel surface. Resin-based substances are sticky and gradually adhere to various parts of the nozzle during wastewater circulation, forming deposits over time. Some additives may react chemically with other components in the wastewater, producing precipitates. These precipitates also accumulate and adhere inside the nozzle, causing blockages that are difficult to clean and reduce subsequent treatment effectiveness. Summary of the Invention

[0005] The purpose of this invention is to provide a wastewater recycling treatment device for masterbatch production, in order to solve the problems mentioned in the background art, such as: with the gradual accumulation of time, the pigment particles in the wastewater are of varying sizes, and some fine particles, carried by the water flow, easily adhere to the inner wall of the nozzle and the surface of the internal flow channels; resinous substances are sticky and will gradually adhere to various parts of the nozzle during wastewater recycling, forming adhesives over time; some additives may react chemically with other components in the wastewater to produce precipitates, which will also accumulate and adhere inside the nozzle, causing blockages, making them difficult to clean, and reducing the effectiveness of subsequent treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wastewater recycling treatment device for masterbatch production, comprising a water pollution treatment tank, a fixing frame fixed to the top of the water pollution treatment tank, and a microbial agent tank fixed to the outside of one side of the water pollution treatment tank. A cylinder is longitudinally fixed to the outside of one side of the fixing frame, and a drive steering component is provided at the output end of the cylinder. A rotating column and a rotating column are symmetrically rotated on both sides of the bottom end of the fixing frame. A disengagement and alignment component is provided on one side of the rotating column, and a blockage clearing and decomposition component is provided on one side of the rotating column. The blockage clearing and decomposition component includes a limiting frame, a plurality of ejector pins, and a sodium hypochlorite solution tank. The limiting frame is laterally arranged on one side of the top of the rotating column. The plurality of ejector pins are longitudinally fixed at equal intervals inside the bottom side of the limiting frame. The sodium hypochlorite solution tank is fixedly installed on the outside of the top side of the limiting frame.

[0007] Furthermore, a mounting bracket is fixedly connected to the top of the fixed frame, and an injection pump is fixedly installed at the top of the mounting bracket. A guide pipe is connected to the input end of the injection pump, and the input end of the guide pipe is fixedly installed inside the bottom side of the microbial agent tank.

[0008] Furthermore, a positioning frame is horizontally fixedly installed inside the fixed frame near the bottom end of the mounting frame. Several discharge pipes are fixedly installed through the positioning frame at equal intervals. A connecting pipe is conductively and fixedly connected between the input ends of the discharge pipes. The input end of the connecting pipe is conductively and fixedly connected to the output end of the injection pump.

[0009] Furthermore, the drive steering assembly includes a limiting rack, a first gear, and a second gear. The limiting rack is longitudinally fixedly installed outside the output end of the first cylinder. The first gear and the second gear are symmetrically meshed and connected to the outside of both sides of the limiting rack. One side of the first gear is fixedly installed to one end of the first rotating column, and one side of the second gear is fixedly installed to one end of the second rotating column.

[0010] Furthermore, the disengagement and alignment assembly includes several nozzles and several baffles. The nozzles are fixedly inserted into the interior of the rotating column at equal intervals. One end of each baffle is fixedly installed on the outside of the bottom end of a discharge pipe on the corresponding side. The baffles are all semi-circular arc-shaped. Flexible sealing rings are fixedly installed at the input ends of the nozzles. A collection cover is fixedly installed on the outside of the side of the fixing frame near the bottom end of the nozzles.

[0011] Furthermore, a cylinder is longitudinally fixedly installed at the middle position of the top of the rotating column two. The top of the cylinder is fixedly installed on one side of the bottom of the limiting frame. A through hole is provided inside the rotating column two on the side near each ejector pin. The bottom of each ejector pin is provided through the through hole on the corresponding side. A piston cylinder is longitudinally arranged on the outside of one side of each ejector pin. One side of the piston cylinder is fixedly installed on the outside of one side of the limiting frame by a fixing seat.

[0012] Furthermore, each piston cylinder has a longitudinally arranged abutment rod at its bottom end, and a piston block is fixedly installed at the top end of each abutment rod. The piston block is slidably and sealingly installed inside the piston cylinder on the corresponding side. A one-way liquid inlet valve pipe is provided through and conductively on one side of the top end of the piston cylinder. The input end of the one-way liquid inlet valve pipe is fixedly installed inside the bottom side of the sodium hypochlorite solution tank.

[0013] Furthermore, a one-way drain valve tube is provided through the other side of the top of the piston cylinder, and a through cavity is opened inside the top of each ejector pin. The output end of the one-way drain valve tube is fixedly installed inside the through cavity at the top of the ejector pin.

[0014] Furthermore, each of the pins has an embedded annular groove around the outer side of the conductive cavity. Several drainage holes are provided at equal angles around the bottom wall of the annular groove and the interior of the conductive cavity. A sponge ring is fitted and fixed to the outer surface of the annular groove.

[0015] Furthermore, an abutment block is fixedly installed at the bottom end of the abutment rod, and the bottom wall of the abutment block abuts against and fits against one side of the outer surface of the rotating column II. A retaining ring is fixedly sleeved on the outside of the bottom end of the piston cylinder, and a return spring is sleeved on the outside of the abutment rod. The two ends of the return spring are respectively fixedly installed on one side of the abutment block and the retaining ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Through the coordinated operation of the drive steering component and the disengagement alignment component, several nozzles can be rotated synchronously and disengaged from several discharge pipes during cleaning. This ensures that impurities at the subsequent unblocking points will not come into contact with the discharge pipes and will be directly discharged and collected, ensuring the effectiveness of unblocking. At the same time, in conjunction with the synchronous operation of the unblocking decomposition component, the mechanical thrust of the ejector pin is used to directly act on the blockages in the nozzle micro-orifices and flow channels. The diameter of the ejector pin is precisely matched with the size of the nozzle micro-orifice, which can penetrate into narrow flow channels that are difficult to reach with traditional tools. Through axial movement, solid or semi-solid blockages are crushed, pushed, or carried out, solving the problem of blind spots in cleaning caused by complex structure. Compared with the traditional manual disassembly and cleaning method, ejector pin unblocking does not require stopping the machine to disassemble the nozzles. The unblocking program can be triggered periodically during equipment operation, reducing the unblocking time of a single unblocking session from several hours to several minutes, greatly improving cleaning efficiency and ensuring the treatment effect of subsequent spraying of microbial agents for water pollution treatment.

[0018] 2. During the unblocking and decomposition process, the sponge ring wrapped around the ejector pin absorbs sodium hypochlorite solution. As the ejector pin is inserted into the nozzle to clear blockages, the sponge ring makes full contact with the inner wall and flow channel surface of the nozzle, releasing the sodium hypochlorite solution. Sodium hypochlorite, as a strong oxidant, can quickly decompose residual resin polymers or other organic adhesives, destroying their molecular structure and transforming them from solid or gel-like substances into liquid or small molecule substances. When microbial agents are subsequently added to the nozzle, the decomposition products are carried out by the flow impact of the agents. This device can effectively clean the residual blockages inside the nozzle through a dual mechanism of physical pushing and chemical dissolution, ensuring the treatment effect of subsequent water pollution.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 5A wastewater recycling treatment device for masterbatch production includes a water pollution treatment tank 1, a fixing frame 2 fixed to the top of the water pollution treatment tank 1, and a microbial agent tank 4 fixed to the outside of one side of the water pollution treatment tank 1. A cylinder 7 is longitudinally fixed to the outside of one side of the fixing frame 2. A drive steering component is provided at the output end of the cylinder 7. Rotating columns 11 and 2 are symmetrically rotated inside the bottom two sides of the fixing frame 2. A disengagement component is provided on one side of the rotating column 11, and a blockage clearing and decomposition component is provided on one side of the rotating column 2. The blockage clearing and decomposition component includes a limiting frame 20, a plurality of ejector pins 21, and a sodium hypochlorite solution tank 29. The limiting frame 20 is horizontally arranged on one side of the top of the rotating column 2. The plurality of ejector pins 21 are longitudinally fixed at equal intervals inside the bottom side of the limiting frame 20. The sodium hypochlorite solution tank 29 is fixedly installed on the outside of the top side of the limiting frame 20.

[0033] A mounting bracket 3 is fixedly connected to the top of the mounting bracket 2. An injection pump 5 is fixedly installed on the top of the mounting bracket 3. A guide pipe 6 is fixedly connected to the input end of the injection pump 5. The input end of the guide pipe 6 is fixedly installed inside the bottom side of the microbial agent tank 4.

[0034] A positioning frame 14 is horizontally fixedly installed inside the bottom side of the mounting frame 2 near the mounting frame 3. Several discharge pipes 15 are fixedly installed through the positioning frame 14 at equal intervals. A connecting pipe 13 is connected to the input ends of the discharge pipes 15. The input end of the connecting pipe 13 is connected to the output end of the injection pump 5.

[0035] The drive steering assembly includes a limiting rack 8, a first gear 9, and a second gear 10. The limiting rack 8 is longitudinally fixedly installed outside the output end of the first cylinder 7. The first gear 9 and the second gear 10 are symmetrically meshed and connected to the outside of both sides of the limiting rack 8. One side of the first gear 9 is fixedly installed to one end of the rotating column 11, and one side of the second gear 10 is fixedly installed to one end of the rotating column 12.

[0036] The disengagement assembly includes several nozzles 16 and several baffles 18. The nozzles 16 are evenly spaced and fixed inside the rotating column 11. One end of each baffle 18 is fixedly installed on the outside of the bottom end of a discharge pipe 15 on the corresponding side. The baffles 18 are all semi-circular arc-shaped. Flexible sealing rings 17 are fixedly installed at the input end of each nozzle 16. A collection cover 36 is fixedly installed on the outside of the fixing frame 2 near the bottom end of the nozzles 16.

[0037] Specifically, the flexible sealing ring 17 and the semi-circular baffle 18 limit the flow, so that when the nozzle 16 is rotated and reset after the subsequent unclogging is completed, it can accurately seal and connect with the output end of the discharge pipe 15, ensuring the subsequent liquid supply effect.

[0038] A cylinder 19 is longitudinally fixed at the middle position of the top of the rotating column 2 12. The top of the cylinder 19 is fixed to the bottom side of the limit frame 20. A through hole 22 is passed through the inside of the rotating column 2 12 near each ejector pin 21. The bottom of each ejector pin 21 passes through the through hole 22 on the corresponding side.

[0039] In this embodiment, after the entire device has been used for a certain period of time, when it is necessary to clean the blockages of several nozzles 16 inside the water pollution treatment tank 1 in the wastewater recycling treatment device, the injection pump 5 is stopped. Then, the start cylinder 7 is activated. The operation of cylinder 7 drives the limit rack 8 to retract. When the limit rack 8 retracts, it drives the meshing gears 9 and 10 on both sides to rotate synchronously. The rotation of gears 9 and 10 drives the rotating column 11 and 12 on one side to rotate synchronously. When the rotating column 11 rotates, it drives several nozzles 16 fixed inside it to rotate 90 degrees synchronously. The placement is changed from horizontal to horizontal, allowing multiple nozzles 16 to rotate synchronously and detach from multiple discharge pipes 15 during cleaning. This ensures that impurities at the blockage site will not come into contact with the inside of the discharge pipes 15 and will be directly discharged and collected, ensuring the effectiveness of the blockage removal. At the same time, it also ensures that the multiple nozzles 16 rotate and align with multiple pins 21 on the side, ensuring the accuracy of the alignment during subsequent blockage removal. Furthermore, it ensures that after the blockage removal is completed and the pins 21 are reset, they will not align with the multiple nozzles 16. The parallel placement of the two will prevent interference between them, thus preventing the bacterial agent from being sprayed and adhering to the surface of the pins 21 during subsequent discharge of bacterial agent from the multiple nozzles 16, ensuring the overall effectiveness of subsequent use.

[0040] It should also be noted that when the rotating column 12 rotates, it will drive the cylinder 19, the limit bracket 20, and several ejector pins 21 to rotate synchronously by 90 degrees, thereby aligning the ejector pins 21 with several nozzles 16 (e.g., Figure 11 As shown), after alignment, the second cylinder 19 is activated, which drives the limit frame 20 and several ejector pins 21 to move synchronously a distance. This allows the ejector pins 21 to be aligned and inserted into the nozzles 16. The mechanical thrust of the ejector pins 21 directly acts on the blockages in the micro-holes and channels of the nozzles 16. The diameter of the ejector pins 21 is precisely matched with the size of the micro-holes in the nozzles 16, allowing them to penetrate into narrow channels that are difficult for traditional tools to reach. Through axial movement, they crush, push, or carry out solid or semi-solid blockages. At the same time, the blockages carried out fall into the collection hood 36 on one side, solving the problem of blind spots caused by the complex structure. Compared with the traditional manual disassembly and cleaning method, the ejector pins 21 can clear blockages without stopping the machine to disassemble the nozzles 16. The clearing program can be automatically triggered periodically during equipment operation, reducing the single clearing time from several hours to several minutes, greatly improving cleaning efficiency and ensuring the treatment effect of subsequent spraying of microbial agents on the nozzles 16 for water pollution treatment.

[0041] At the same time, after the overall unblocking is completed, the cylinder 19 can be extended and reset by controlling the cylinder to drive several pins 21 to disengage from the nozzle 16. Then, the limit rack 8 can be extended and reset by controlling the cylinder 7, so that the gear 9 and gear 10 drive the rotating column 11 and rotating column 22 to rotate 90 degrees in opposite directions to reset, thus completing the unblocking. After that, the injection pump 5 is restarted. With the guidance of the guide pipe 6 and the connection of the connecting pipe 13 to several discharge pipes 15, the injection pump 5 will inject the microbial agent in the microbial agent tank 4 into the water pollution treatment tank 1 to continue to treat the masterbatch production wastewater inside the water pollution treatment tank 1.

[0042] Example 2: Please refer to Figure 6 - Figure 10 This embodiment further illustrates Example 1: each ejector pin 21 has a piston cylinder 23 longitudinally arranged on one side of its outer surface, and one side of the piston cylinder 23 is fixedly installed on the outer side of the limiting frame 20 by a fixing seat.

[0043] Each piston cylinder 23 has a longitudinally arranged abutment rod 24 at its bottom end, and a piston block 26 is fixedly installed at the top of each abutment rod 24. The piston block 26 is slidably and sealingly installed inside the piston cylinder 23 on the corresponding side. A one-way liquid inlet valve pipe 30 is provided through and conductive on one side of the top end of the piston cylinder 23. The input end of the one-way liquid inlet valve pipe 30 is fixedly installed inside the bottom side of the sodium hypochlorite solution tank 29.

[0044] A one-way drain valve tube 31 is provided through the other side of the top of the piston cylinder 23. A through cavity 32 is opened inside the top of each ejector pin 21. The output end of the one-way drain valve tube 31 is fixedly installed inside the through cavity 32 at the top of the ejector pin 21.

[0045] Each pin 21 has an embedded annular groove 33 around the outer side of the side near the conductive cavity 32. Several drainage holes 35 are provided at equal angles around the bottom wall of the annular groove 33 and the interior of the conductive cavity 32. A sponge ring 34 is fitted and fixed to the outer surface of the annular groove 33.

[0046] A contact block 25 is fixedly installed at the bottom end of the contact rod 24. The bottom wall of the contact block 25 is in contact with and fits against one side of the outer surface of the rotating column 12. A retaining ring 27 is fixedly sleeved on the bottom end of the piston cylinder 23. A return spring 28 is sleeved on the outside of the contact rod 24. The two ends of the return spring 28 are respectively fixedly installed on one side of the contact block 25 and the retaining ring 27.

[0047] In this embodiment, when cylinder 219 moves the limiting frame 20 and ejector pin 21 to physically block the nozzle 16, the limiting frame 20, during its movement, causes the contact rod 24 to be blocked by the rotating column 22. This causes the piston block 26 to squeeze inside the piston cylinder 23, thereby forcing the sodium hypochlorite solution originally drawn into the piston cylinder 23 into the guiding cavity 32 inside the ejector pin 21 through the existing one-way drainage valve pipe 31. Then, through the opening of several drainage holes 35, the sponge ring 34 can absorb the sodium hypochlorite solution in the guiding cavity 32, allowing the ejector pin 21 to then... While the sponge ring 34 is inserted into the nozzle 16 to clear blockages, it makes full contact with the inner wall and flow channel surface of the nozzle 16, releasing sodium hypochlorite solution. Sodium hypochlorite, as a strong oxidant, can quickly decompose residual resin polymers or other organic adhesives, destroying their molecular structure and transforming them from solid or gel-like to liquid or small molecule substances. When microbial agents are subsequently added to the nozzle 16, the decomposition products are carried out by the flow impact of the agents. This allows the device to effectively clean the residual blockages inside the nozzle 16 through a dual mechanism of physical pushing and chemical dissolution, ensuring the treatment effect of subsequent water pollution.

[0048] It should also be noted that when cylinder 219 drives the limit frame 20 and the ejector pin 21 to return to their original positions, the return spring 28 causes the contact rod 24 to drive the piston block 26 to perform a suction motion inside the piston cylinder 23. With the existing one-way inlet valve pipe 30 open, when the piston block 26 performs suction inside the piston cylinder 23, it can draw a certain amount of the sodium hypochlorite solution pre-injected into the sodium hypochlorite solution tank 29 into the piston cylinder 23, ensuring the subsequent secondary cleaning and drainage operation. This allows the whole system to be recycled and is highly convenient to use.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
