Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment technology, specifically a purification device for industrial wastewater treatment. Background Technology

[0002] Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. Factories generate a large amount of wastewater during the production process, so there is a need for industrial wastewater treatment purification devices.

[0003] A Chinese patent with authorization announcement number CN209276297U discloses a purification device for industrial wastewater treatment, including a box body. An inlet pipe is installed through the left side of the top of the box body, and an outlet pipe is connected to the bottom of the right side of the box body. Slide rails are fixedly connected to the front and rear sides of both sides of the inner cavity of the box body. This utility model solves the problem that the filter screen is easily clogged due to the large amount of particulate impurities in the wastewater, which affects the filtration efficiency of the wastewater and reduces the filtration performance of the wastewater purification device.

[0004] However, the above solutions still have some problems. The treatment device relies on the turbulence of the fluid itself, but the mixing effect of high viscosity or suspended solids wastewater with the reagent is poor, which leads to a reduction in the efficiency of industrial wastewater treatment. Therefore, a purification device for industrial wastewater treatment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a purification device for industrial wastewater treatment.

[0006] The technical solution adopted by this utility model to solve its technical problem is a purification device for industrial wastewater treatment, comprising: a shell, a first drive motor installed on the top of the shell, a square hollow rod fixedly connected to the output end of the first drive motor, a limit rod fixedly connected to the inner upper surface of the shell, the square hollow rod located inside the limit rod, a first internal thread provided inside the limit rod, a connecting rod slidably connected inside the square hollow rod, a screw fixedly connected to one end of the connecting rod, the limit rod and the screw threadedly connected, an adjusting rod fixedly connected to one end of the screw, a stirring fan blade fixedly connected to the outer side of the adjusting rod, and a feeding trough opened on one side of the inner side of the shell, with one side of the feeding trough hinged. The device is equipped with a partition, and a flow guide frame is installed on one side of the outer shell. Two sets of filter screens are installed inside the outer shell, and a second drive motor is installed on the outer side of the outer shell. A bidirectional threaded rod is fixedly connected to the output end of the second drive motor. One end of the bidirectional threaded rod is rotatably connected to the inside of the outer shell. A first moving block is threaded onto the bidirectional threaded rod. The first moving block has a second internal thread. A water-blocking plate is fixedly connected to one side of the first moving block. The two sets of filter screens are located on the upper and lower sides of the water-blocking plate, respectively. By adjusting the height of the adjusting rod and the stirring blades, the stirring height can be adjusted, enabling rapid mixing throughout the entire area during the initial stage of pesticide addition, thereby increasing the probability of contact between pollutants and pesticides.

[0007] Preferably, a connecting frame is installed on one side of the first movable block, and bristles are fixedly connected to the bottom of the connecting frame. A baffle is hinged to the lower surface of the connecting frame, and a limiting plate is fixedly connected to the lower surface of the connecting frame. The limiting plate is located on one side of the baffle and limits the swing amplitude of the baffle. When the connecting frame moves, it drives the baffle to swing, which allows the fibrous material to be collected at the bottom of the connecting frame, thereby improving the cleaning quality of the filter screen.

[0008] Preferably, a second movable block is fixedly connected to one side of the connecting frame, and a slide rod is slidably connected inside the second movable block. The two ends of the slide rod are fixedly connected to the inside of the outer shell. A dosing pipe and a sewage inlet pipe are installed on the upper surface of the outer shell. The second movable block moves on the slide rod driven by the connecting frame, thereby ensuring the stability of the connecting frame and the water-blocking plate when they move.

[0009] Preferably, one end of the sewage inlet pipe is fixedly connected to an anti-slip ring, and a bolt is threaded onto the anti-slip ring. A lint discharge pipe is fixedly connected to the outer side of the diversion frame, and the lint discharge pipe extends into the interior of the discharge trough. A drain pipe is fixedly connected to the outer side of the outer shell. By screwing the bolt into the interior of the anti-slip ring, the ring size is reduced, thereby improving the tightness of the connection between the sewage transmission pipe and the sewage inlet pipe and preventing leakage when industrial sewage enters the outer shell.

[0010] Preferably, the drain pipe and the filament discharge pipe are equipped with control valves, and the outer shell is equipped with a purification component, which includes: an upper layer of activated carbon fiber, a middle layer of sulfonated coal, and a lower layer of diatomaceous earth. The purified industrial wastewater is further purified by the upper layer of activated carbon fiber, the middle layer of sulfonated coal, and the lower layer of diatomaceous earth, which can improve the quality of industrial wastewater purification treatment.

[0011] Preferably, the device is connected to an external control box, which is used to control the start and stop of the first drive motor, the second drive motor and the control valve. The first drive motor, the second drive motor and the control valve are started through the external control box, thereby improving the ease of use of the device.

[0012] The advantages of this utility model are: by running the first drive motor, the screw is driven to rotate, thereby adjusting the height of the adjusting rod and the stirring blades. This allows for adjustment of the stirring height by the stirring blades, enabling rapid mixing of the entire area at the initial stage of reagent addition. This increases the probability of contact between pollutants and reagents, improves the mixing and reaction efficiency of wastewater and reagents, and thus improves the efficiency of industrial wastewater purification.

[0013] This invention uses a second drive motor to rotate a bidirectional threaded rod, adjusting the positions of the connecting frame, brush bristles, and baffles. This allows the brush bristles to clean the flocculent material on the surface of the filter screen, preventing clogging. The flocculent material cleaned by the brush bristles enters between two sets of baffles for collection, and is then discharged through a discharge trough and a flocculation pipe. This prevents the flocculent material from re-adsorbing onto the filter screen, thus avoiding affecting the wastewater filtration efficiency and improving the filtration performance of the industrial wastewater purification device.

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a purification device for industrial wastewater treatment includes: a housing 1, a first drive motor 2 mounted on the top of the housing 1, a square hollow rod 3 fixedly connected to the output end of the first drive motor 2, a limiting rod 5 fixedly connected to the inner upper surface of the housing 1, the square hollow rod 3 located inside the limiting rod 5, the limiting rod 5 having a first internal thread inside, a connecting rod 4 slidably connected inside the square hollow rod 3, a screw 6 fixedly connected to one end of the connecting rod 4, the limiting rod 5 and the screw 6 being threadedly connected, an adjusting rod 7 fixedly connected to one end of the screw 6, a stirring blade 8 fixedly connected to the outer side of the adjusting rod 7, a discharge trough 9 opened on one side of the inner side of the housing 1, a partition hinged to one side of the discharge trough 9, a flow guide frame 901 mounted on one side of the housing 1, two sets of filter screens 10 arranged inside the housing 1, a second drive motor 11 mounted on the outer side of the housing 1, and a bidirectional screw fixedly connected to the output end of the second drive motor 11. A threaded rod 12 is rotatably connected at one end to the inside of the outer casing 1. A first moving block 13 is threadedly connected to the double-threaded rod 12. The first moving block 13 has a second internal thread inside. A water-blocking plate 14 is fixedly connected to one side of the first moving block 13. Two sets of filter screens 10 are located on the upper and lower sides of the water-blocking plate 14, respectively. A connecting frame 15 is installed on one side of the first moving block 13. A brush bristle 16 is fixedly connected to the bottom of the connecting frame 15. A baffle 17 is hinged to the lower surface of the connecting frame 15. A limiting plate 171 is fixedly connected to the lower surface of the connecting frame 15. The limiting plate 171 is located on one side of the baffle 17 and limits the swing amplitude of the baffle 17. A second moving block 18 is fixedly connected to one side of the connecting frame 15. A sliding rod 19 is slidably connected inside the second moving block 18. Both ends of the sliding rod 19 are fixedly connected to the inside of the outer casing 1. A dosing pipe 20 and a sewage inlet pipe 21 are installed on the upper surface of the outer casing 1.

[0023] The factory generates a large amount of wastewater during production, thus requiring a wastewater treatment purification device. In actual use, the wastewater transmission pipe, sludge pump, and inlet pipe 21 are connected. Simultaneously, the purification agent is added to the interior of the outer casing 1 through the dosing pipe 20. The first drive motor 2 is started via an external control box, driving the square hollow rod 3 to rotate. Because both the square hollow rod 3 and the connecting rod 4 are square, the rotation of the square hollow rod 3 drives the screw 6 to rotate via the connecting rod 4. Since the screw 6 is threadedly connected to the limit rod 5, the screw 6... During rotation, the exposed length can be adjusted to regulate the height of the adjusting rod 7 and the stirring blade 8, achieving rapid mixing throughout the entire area during the initial stage of reagent addition. This increases the probability of contact between pollutants and reagents, improves the mixing and reaction efficiency of wastewater and reagents, and reduces the amount of reagent required, thereby lowering industrial wastewater treatment costs. After sufficient reaction time between the reagent and wastewater, the second drive motor 11 is activated via an external control box, driving the bidirectional threaded rod 12 to rotate. Because the threads on the bidirectional threaded rod 12 match the second internal thread of the first moving block 13, the rotation of the bidirectional threaded rod 12... The position adjustment of the first moving block 13 drives the water-blocking plate 14 and the connecting frame 15 to move, so that the water-blocking plate 14 moves out from the opening on one side of the outer shell 1, allowing the purified wastewater to enter the bottom of the outer shell 1 after passing through the two sets of filter screens 10. When the connecting frame 15 moves, it drives the bristles 16 at its bottom to clean the flocculent material on the surface of the filter screen 10 above, preventing the filter screen 10 from being blocked. Because the baffle 17 is in contact with the surface of the filter screen 10, it is affected by the flocculent material and swings towards the bristles 16, causing the flocculent material to enter between the baffle 17 and the bristles 16. The limiting plate 171 restricts the flow of fibrous material, which is collected below the connecting frame 15 when the connecting frame 15 moves, reducing the outward spread of fibrous material. When all the purified wastewater enters the bottom of the outer shell 1, the bidirectional threaded rod 12 rotates, causing the first moving block 13 to return to its original position. One side of the connecting frame 15 pushes the partition plate to rotate, so that the connecting frame 15 enters the interior of the discharge trough 9, thereby allowing the cleaned fibrous material to enter the discharge trough 9 and the diversion frame 901. The control valve is activated by the external control box, so that the fibrous discharge pipe 24 is in an open state, and the fibrous material can be discharged for subsequent use.

[0024] Please see Figure 1-5 As shown, an anti-slip ring 22 is fixedly connected to one end of the sewage inlet pipe 21, and a bolt 23 is threaded onto the anti-slip ring 22. A lint discharge pipe 24 is fixedly connected to the outside of the diversion frame 901, and the lint discharge pipe 24 extends into the inside of the discharge trough 9. A drain pipe 25 is fixedly connected to the outside of the outer shell 1. Control valves are installed inside the drain pipe 25 and the lint discharge pipe 24. A purification component 26 is installed inside the outer shell 1. The purification component 26 includes: an upper layer of activated carbon fiber, a middle layer of sulfonated coal, and a lower layer of diatomaceous earth. At the bottom of the outer shell 1, an external control box is connected to the device. The external control box is used to control the start and stop of the first drive motor 2, the second drive motor 11, and the control valves.

[0025] When the sewage transmission pipe is connected to the inlet pipe 21, the sewage transmission pipe is located inside the anti-slip ring 22. Then, the bolt 23 is screwed into the anti-slip ring 22 to reduce the ring size, thereby improving the tightness of the connection between the sewage transmission pipe and the inlet pipe 21 and preventing leakage when industrial sewage enters the outer shell 1. After purification, the sewage falls into the purification component 26. After further purification by the upper activated carbon fiber, the middle sulfonated coal, and the lower diatomaceous earth, the purified industrial sewage is discharged from the inside of the outer shell 1 by activating the control valve on the drain pipe 25 through the external control box, thus completing the purification of industrial sewage.

[0026] Working principle: When the sewage transmission pipe is connected to the inlet pipe 21, the sewage transmission pipe is located inside the anti-slip ring 22. Then, the bolt 23 is screwed into the anti-slip ring 22 to reduce the ring size, thereby improving the tightness of the connection between the sewage transmission pipe and the inlet pipe 21. Industrial sewage is pumped into the sewage transmission pipe and the inlet pipe 21 by a sewage pump. At the same time, the purification agent is added into the interior of the outer casing 1 through the dosing pipe 20. The first drive motor 2 is started through the external control box, which drives the square hollow rod 3, the connecting rod 4 and the screw 6 to rotate, thereby adjusting the exposed length of the screw 6 and the position of the stirring blade 8 to achieve rapid mixing of the entire area in the initial stage of agent addition. After the agent and sewage have reacted sufficiently, the second drive motor 11 is started through the external control box, which drives the bidirectional threaded rod 12 to rotate, which rotates the first moving block 13 and the water blocking plate 1. 4. Adjust the position of the connecting frame 15, and the water-blocking plate 14 moves out from the opening on one side of the outer shell 1, so that the purified sewage enters the purification component 26 after passing through two sets of filter screens 10. After being purified again by the upper activated carbon fiber, the middle sulfonated coal and the lower diatomaceous earth, the control valve on the drain pipe 25 is activated by the external control box, so that the purified sewage can be discharged from the inside of the outer shell 1, thereby completing the purification of industrial sewage. While the connecting frame 15, brush 16 and baffle 17 move, the flocculent material on the surface of the upper filter screen 10 is cleaned. After the first moving block 13 returns to its original position, it pushes the partition to rotate, so that the connecting frame 15 enters the inside of the feeding trough 9 and the diversion frame 901, so that the control valve is activated by the external control box, so that the flocculent discharge pipe 24 is in an open state, and the flocculent material can be discharged for subsequent use.
