Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to a device for treating high-concentration organic wastewater. Background Technology

[0002] With the rapid development of industrialization, the treatment of high-concentration organic wastewater has become a major challenge in the field of environmental protection. This type of wastewater usually contains a large amount of recalcitrant organic matter (such as oils, dyes, pesticide residues, etc.), and is characterized by high chemical oxygen demand (COD), strong toxicity, and complex composition. If it is discharged directly without effective treatment, it will cause serious harm to aquatic ecosystems and human health. At present, the main technologies for the treatment of high-concentration organic wastewater include physical adsorption, chemical oxidation, biodegradation, and their combined processes.

[0003] However, existing technologies still have many shortcomings. Most existing treatment devices on the market only have a single-use filtration mechanism, and the cleaning effect of a single filtration is not ideal. The equipment needs to be used repeatedly for filtration, which increases equipment wear and tear and increases treatment costs. Moreover, repeated drainage and filling will increase the treatment time, making it difficult to meet the needs of large-scale industrial applications. In addition, the physical filtration mechanism in most traditional treatment devices only filters high-concentration organic wastewater by placing it in a container for sedimentation. This is prone to clogging of the filter screen by suspended solids and colloidal substances, resulting in a decrease in treatment efficiency. Frequent cleaning also leads to high maintenance costs.

[0004] Therefore, there is an urgent need to develop an integrated device that combines efficient stirring, dynamic filtration, and convenient cleaning functions to improve the treatment efficiency and economy of high-concentration organic wastewater. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-concentration organic wastewater treatment device. Through an innovative design of a coordinated working mechanism between the linkage stirring mechanism and the driving filtration mechanism, the solid-liquid separation process is optimized. At the same time, combined with multi-stage cleaning ports and a modular structure, the treatment efficiency is significantly improved, and the treatment time and maintenance costs are reduced.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-concentration organic wastewater treatment device includes a support frame, a loading mechanism fixedly connected to the upper side of the support frame, a linkage stirring mechanism inside the loading mechanism, and a drive filtration mechanism fixedly connected to one side of the outer wall of the loading mechanism. The loading mechanism includes a housing fixedly connected to the upper side of the support frame, an upper cleaning port fixedly connected to one side of the middle outer wall of the housing, and a lower cleaning port fixedly connected to one side of the lower outer wall of the housing. Two fixed rods are fixedly connected to the top of the housing, and the same fixed sleeve is fixedly connected between the upper middle sides of the two fixed rods.

The driving filter mechanism includes a rotating column rotatably connected to the middle of the lower side of the housing, a filter disc fixedly connected to the top of the rotating column, and a pulley fixedly connected to the bottom of the rotating column. A limit assembly is fixedly connected to the outer wall of the top side of the housing. Furthermore, the top of the loading mechanism is hinged to a top cover, the bottom of the housing is fixedly connected to a drain pipe, the upper cleaning port, the lower cleaning port and the limiting component are not on the same side, a filter plate is fixedly connected to the lower inner wall of the housing, the filter hopper is located inside the lower end of the housing, the filter hopper is located below the filter plate, the upper cleaning port is located above the filter plate, and the lower cleaning port is located between the filter hopper and the filter plate. Furthermore, a motor is fixedly connected to the side of the limiting component away from the outer shell, a shaft is fixedly connected to the lower output end of the motor, and a pulley is fixedly connected to the end of the shaft away from the motor. The outer wall of the pulley is connected to the outer wall of the pulley and the pulley is connected by a synchronous belt. Furthermore, a rotating shaft is fixedly connected to the upper output end of the motor, and a bevel gear three is fixedly connected to the top end of the rotating shaft. A support member is fixedly connected to the upper middle part of the limiting component, and a rotating rod is rotatably connected to the top middle part of the support member. A bevel gear two is fixedly connected to the end of the rotating rod near the bevel gear three, and a bevel gear one is fixedly connected to the end of the rotating rod away from the bevel gear two. The bevel gear two and the bevel gear three mesh with each other. Furthermore, the limiting component includes a fixing member fixedly connected to the outer wall of one side of the top of the housing, a cavity opened in the middle of the upper side of the fixing member, and an inner cavity opened in the bottom wall of the inner cavity. A sliding block is slidably connected to the middle of the cavity. A connecting column is fixedly connected to the middle of the upper side of the sliding block. A positioning block is fixedly connected to the upper side of the connecting column. The bottom end of the support member is fixedly connected to the upper side of the positioning block. The positioning block is located in the middle of the top of the cavity. A tension spring is fixedly connected to the middle of the lower side of the sliding block. The end of the tension spring away from the sliding block is rotatably connected to the inner bottom wall of the inner cavity. Furthermore, the linkage stirring mechanism includes a main gear rotatably connected to the lower side of the fixed sleeve, a cross fixedly connected to the lower side of the main gear, and a rotating inner ring fixedly connected to the outside of the cross. The rotating inner ring and the fixed outer ring are on the same horizontal plane. The rotating inner ring is located in the middle of the fixed outer ring. A secondary gear one and a secondary gear two are respectively provided on the two sides of the main gear. A toothed ring is fixedly connected to the top inner wall of the outer shell. Furthermore, both the auxiliary gear one and the auxiliary gear two mesh with the main gear. The outer wall of the auxiliary gear one away from the main gear meshes with the inner wall of the gear ring, and the outer wall of the auxiliary gear two away from the main gear meshes with the inner wall of the gear ring. Furthermore, an agitator 2 is fixedly connected to the lower center of the secondary gear 1, and an agitator 1 is fixedly connected to the lower center of the secondary gear 2. Both the secondary gear 1 and the secondary gear 2 are disposed on the upper side of the rotating inner ring and the fixed outer ring. The end of the agitator 1 near the secondary gear 2 is disposed between the fixed outer ring and the rotating inner ring, and the end of the agitator 2 near the secondary gear 1 is disposed between the fixed outer ring and the rotating inner ring. Furthermore, a fixed connecting post is fixedly connected to the upper middle part of the main gear, and a bevel gear four is fixedly connected to the top of the fixed connecting post. The fixed connecting post is located in the middle of the fixed sleeve. The bevel gear one and the bevel gear four mesh with each other. The agitator one and the agitator two are both located above the filter plate. The position of the fixed sleeve corresponds to the position of the middle part of the top cover.

[0007] The present invention has the following beneficial effects: In this invention, the combination of the outer shell, filter plate, and driving filtration mechanism alleviates the problem that most existing processing devices on the market only have a single-use filtration mechanism, resulting in unsatisfactory single-use filtration and cleaning effects. This necessitates repeated use of the equipment for filtration, increasing equipment wear and tear and processing costs. Furthermore, repeated drainage and irrigation increase processing time, making it difficult to meet the needs of large-scale industrial applications.

[0008] In this invention, the loading mechanism and the linkage stirring mechanism work together to alleviate the problems of most traditional treatment devices where the physical filtration mechanism simply places high-concentration organic wastewater in a container for sedimentation and filtration. This is because such physical filtration mechanisms are prone to clogging the filter screen due to suspended solids and colloidal substances, resulting in reduced treatment efficiency and high maintenance costs due to frequent cleaning.

[0011] 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.

[0012] Reference Figure 1-13 An embodiment of the present invention provides a high-concentration organic wastewater treatment device, including a support frame 1, a loading mechanism 2 fixedly connected to the upper side of the support frame 1, a linkage stirring mechanism 4 provided inside the loading mechanism 2, and a drive filtration mechanism 3 fixedly connected to one side of the outer wall of the loading mechanism 2. The loading mechanism 2 includes a housing 21 fixedly connected to the upper side of the support frame 1, an upper cleaning port 22 fixedly connected to one side of the middle outer wall of the housing 21, and a lower cleaning port 23 fixedly connected to one side of the lower outer wall of the housing 21. After the equipment is shut down, the solid residue above the filter plate 29 during the processing can be periodically removed through the upper cleaning port 22, while the impurities accumulated between the filter disc 313 and the filter plate 29 are cleaned through the lower cleaning port 23. Two fixed rods 24 are fixedly connected to the top of the housing 21, and the same fixed sleeve 25 is fixedly connected between the upper middle side of the two fixed rods 24. Multiple fixed rods 26 are evenly fixedly connected to the upper inner wall of the housing 21, and the same fixed outer ring 27 is fixedly connected to the end of the multiple fixed rods 26 away from the inner wall of the housing 21. The driving filtration mechanism 3 includes a rotating column 311 rotatably connected to the middle of the lower side of the housing 21, a filter disc 313 fixedly connected to the top of the rotating column 311, and a second pulley 312 fixedly connected to the bottom of the rotating column 311. When high-concentration organic wastewater is injected into the housing 21 of the loading mechanism 2, the motor 36 starts and drives the first pulley 310 to rotate through the drive shaft 39 at the lower output end. The rotation is transmitted to the second pulley 312 via the synchronous belt 314, so that the rotating column 311 and the filter disc 313 rotate synchronously, forming the initial power for dynamic filtration. A limit assembly 32 is fixedly connected to the outer wall of the top side of the housing 21.

[0013] The top hinge of the loading mechanism 2 is connected to the top cover 5. Before using this equipment, place it in the desired position, lift the support 31, and pull the positioning block 326, connecting column 325, and sliding block 324. This causes the sliding block 324 to slide upward inside the cavity 322, disengaging the first bevel tooth 34 from the fourth bevel tooth 44, the second bevel tooth 35 from the third bevel tooth 38, and the positioning block 326 from the cavity 322. When the connecting column 325 is at the top center of the cavity 322, the support 31 and its upper structure can be rotated, and the rotating rod 33 rotates away from the top cover 5. At this point, the top cover 5 can be opened to facilitate the subsequent injection of wastewater into the equipment. Then, the support member 31 and its upper structure are rotated back. Under the pull of the tension spring 327, the sliding block 324, connecting column 325, and positioning block 326 retract. The positioning block 326 engages with the top center of the cavity 322, and the bevel gear 2 35 and bevel gear 38 re-engage. The positioning block 326 also re-engages with the cavity 322, facilitating subsequent equipment operation. Because the weight of the support member 31 and its upper structure, combined with the tension of the tension spring 327, prevents the bevel gear 2 35 from engaging with the bevel gear 38 during equipment operation. The gear 38, positioning block 326, and cavity 322 are disengaged from each other. This design can also buffer vibrations during transmission, ensure stable gear meshing, and reduce equipment wear. After use, the top cover 5 can be replaced to prevent debris from accidentally falling into the casing 21 and affecting subsequent equipment use. A drain pipe 28 is fixedly connected to the bottom of the casing 21. The upper cleaning port 22, lower cleaning port 23, and limiting component 32 are not on the same side. A filter plate 29 is fixedly connected to the lower inner wall of the casing 21, and the filter hopper 313 is located inside the lower end of the casing 21. The filter hopper 313 is located below the filter plate 29, the upper cleaning port 22 is located above the filter plate 29, and the lower cleaning port 23 is located between the filter hopper 313 and the filter plate 29. The stirred wastewater flows through the filter plate 29 under the action of gravity, completing the initial solid-liquid separation and intercepting large particles. Subsequently, the wastewater enters the rotating filter hopper 313 below. Under the action of centrifugal force, the fine particles are further thrown to the edge of the hopper and intercepted. The clean water is collected at the bottom of the outer shell 21 after being intercepted by both the filter plate 29 and the filter hopper 313, and discharged through the drain pipe 28.

[0014] A motor 36 is fixedly connected to the side of the limiting component 32 away from the outer shell 21. A shaft 39 is fixedly connected to the lower output end of the motor 36. A pulley 310 is fixedly connected to the end of the shaft 39 away from the motor 36. The outer wall of the pulley 310 is connected to the outer wall of the pulley 312 via a synchronous belt 314.

[0015] A rotating shaft 37 is fixedly connected to the upper output end of the motor 36. A bevel gear 38 is fixedly connected to the top of the rotating shaft 37. A support member 31 is fixedly connected to the upper middle part of the limiting component 32. A rotating rod 33 is rotatably connected to the top middle part of the support member 31. A bevel gear 35 is fixedly connected to the end of the rotating rod 33 near the bevel gear 38, and a bevel gear 34 is fixedly connected to the end of the rotating rod 33 away from the bevel gear 35. The bevel gear 35 and the bevel gear 38 mesh with each other. The upper output end of the motor 36 drives the rotating shaft 37 to rotate. Through the meshing of the bevel gear 38 and the bevel gear 35, the rotating rod is driven. 33 and bevel gear 34 rotate, and bevel gear 34 meshes with bevel gear 44 at the top of main gear 42, driving main gear 42 to rotate. Main gear 42 meshes with gear ring 41 through auxiliary gear 47 and auxiliary gear 48, driving agitator 49 and agitator 410 to rotate at high speed between fixed outer ring 27 and rotating inner ring 46. This design allows agitator 49 and agitator 410 to revolve around main gear 42 while rotating on their own axis, thereby strongly agitating wastewater, breaking colloidal stability and promoting the dispersion of suspended solids, and preventing filter plate 29 from clogging.

[0016] The limiting component 32 includes a fixing member 321 fixedly connected to the outer wall of the top side of the housing 21, a cavity 322 opened in the middle of the upper side of the fixing member 321, and an inner cavity 323 opened in the bottom wall of the cavity 322. A sliding block 324 is slidably connected to the middle of the cavity 322. A connecting post 325 is fixedly connected to the middle of the upper side of the sliding block 324. A positioning block 326 is fixedly connected to the upper side of the connecting post 325. The bottom end of the support member 31 is fixedly connected to the upper side of the positioning block 326. The positioning block 326 is located in the middle of the top of the cavity 322. A tension spring 327 is fixedly connected to the middle of the lower side of the sliding block 324. The end of the tension spring 327 away from the sliding block 324 is rotatably connected to the bottom wall of the inner cavity 323.

[0017] The linkage stirring mechanism 4 includes a main gear 42 rotatably connected to the lower side of the fixed sleeve 25, a cross 45 fixedly connected to the lower side of the main gear 42, and a rotating inner ring 46 fixedly connected to the outside of the cross 45. The rotating inner ring 46 and the fixed outer ring 27 are on the same horizontal plane. The rotating inner ring 46 is located in the middle of the fixed outer ring 27. A secondary gear 47 and a secondary gear 48 are respectively provided on the two sides of the main gear 42. A toothed ring 41 is fixedly connected to the top inner wall of the outer casing 21.

[0018] Both auxiliary gear 1 47 and auxiliary gear 2 48 mesh with the main gear 42. The outer wall of auxiliary gear 1 47 away from the main gear 42 meshes with the inner wall of the gear ring 41, and the outer wall of auxiliary gear 2 48 away from the main gear 42 meshes with the inner wall of the gear ring 41.

[0019] A stirring element 410 is fixedly connected to the lower middle part of the secondary gear 47, and a stirring element 49 is fixedly connected to the lower middle part of the secondary gear 48. Both the secondary gear 47 and the secondary gear 48 are located on the upper side of the rotating inner ring 46 and the fixed outer ring 27. The end of the stirring element 49 near the secondary gear 48 is located between the fixed outer ring 27 and the rotating inner ring 46, and the end of the stirring element 410 near the secondary gear 47 is located between the fixed outer ring 27 and the rotating inner ring 46.

[0020] A fixed post 43 is fixedly connected to the upper middle part of the main gear 42. A bevel gear 44 is fixedly connected to the top of the fixed post 43. The fixed post 43 is located in the middle of the fixed sleeve 25. The bevel gear 34 and the bevel gear 44 mesh with each other. The agitator 49 and the agitator 410 are both located above the filter plate 29. The position of the fixed sleeve 25 corresponds to the position of the middle part of the top cover 5.

[0021] Working Principle: Before using this equipment, place it in the desired position, lift the support 31, and pull the positioning block 326, connecting column 325, and sliding block 324. This causes the sliding block 324 to slide upward inside the cavity 322, disengaging the first bevel tooth 34 from the fourth bevel tooth 44, the second bevel tooth 35 from the third bevel tooth 38, and the positioning block 326 from the cavity 322. When the connecting column 325 is at the top center of the cavity 322, the support 31 and its upper structure can be rotated. The rotating rod 33 rotates away from the top cover 5, allowing the top cover 5 to be opened for subsequent injection of wastewater into the equipment. Then, rotate the support 31 and its upper structure back. Under the pull of the tension spring 327, the sliding block 324, connecting column 325, and positioning block 326 retract, and the positioning block 326... The bevel gear 35 and bevel gear 38 re-engage, and the positioning block 326 re-engages with the cavity 322, facilitating subsequent equipment operation. The weight of the support member 31 and its upper structure, combined with the tension of the spring 327, prevents the bevel gear 35 and bevel gear 38, and the positioning block 326 from disengaging from the cavity 322 during operation. This design also buffers vibrations during transmission, ensuring stable gear meshing and reducing equipment wear. After use, the top cover 5 can be replaced to prevent accidental entry of debris into the outer casing 21, which could affect subsequent equipment use. High-concentration organic wastewater is injected into the outer casing 21 of the loading mechanism 2, and the motor 36 starts, driving the pulley 310 to rotate via the lower output shaft 39. The wastewater is then transported via a synchronous belt. 314 drives the pulley 312, causing the rotating column 311 and the filter disc 313 to rotate synchronously, forming the initial power for dynamic filtration. The upper output end of the motor 36 drives the rotating shaft 37 to rotate. Through the meshing of the bevel gear 38 and the bevel gear 25, the rotating rod 33 and the bevel gear 1 34 rotate. The bevel gear 1 34 meshes with the bevel gear 44 at the top of the main gear 42, driving the main gear 42 to rotate. The main gear 42 meshes with the gear ring 41 through the auxiliary gear 1 47 and the auxiliary gear 2 48, driving the agitator 1 49 and the agitator 2 410 to rotate at high speed between the fixed outer ring 27 and the rotating inner ring 46. This design allows the agitator 1 49 and the agitator 2 410 to revolve around the main gear 42 while rotating on their own axis, thereby strongly agitating the wastewater and breaking the colloidal stability. It promotes the dispersion of suspended solids and prevents the filter plate 29 from clogging. The stirred wastewater flows through the filter plate 29 under the action of gravity, completing the initial solid-liquid separation and intercepting large particles. Subsequently, the wastewater enters the rotating filter hopper 313 below. Under the action of centrifugal force, the fine particles are further thrown to the edge of the hopper and intercepted. The clean water is collected at the bottom of the outer shell 21 after being intercepted by the filter plate 29 and the filter hopper 313, and discharged through the drain pipe 28. After the equipment is stopped, the solid residue above the filter plate 29 during the treatment process can be periodically removed through the upper cleaning port 22, while the impurities accumulated between the filter hopper 313 and the filter plate 29 are cleaned through the lower cleaning port 23. The linkage stirring mechanism 4 and the drive filtration mechanism 3 achieve synchronous operation of stirring and filtration through the precise cooperation of gears, bevel gears and synchronous belts.This design not only improves solid-liquid separation efficiency, but also reduces the risk of filter clogging through dynamic filtration, significantly reducing the frequency of downtime for cleaning. It is suitable for large-scale continuous treatment of high-concentration, high-viscosity organic wastewater. Through the integrated stirring-filtration design, it avoids the inefficiency problem of traditional static filtration. Multi-stage cleaning ports and modular structure simplify the maintenance process and reduce operating costs. The gear transmission system works synergistically with centrifugal filtration to improve processing capacity and stability.

The rotating inner ring (46) and the fixed outer ring (27) are on the same horizontal plane. The rotating inner ring (46) is located in the middle of the fixed outer ring (27). The two sides of the main gear (42) are respectively provided with a secondary gear one (47) and a secondary gear two (48). A toothed ring (41) is fixedly connected to the top inner wall of the outer shell (21). Both the first auxiliary gear (47) and the second auxiliary gear (48) mesh with the main gear (42). The outer wall of the first auxiliary gear (47) away from the main gear (42) meshes with the inner wall of the gear ring (41). The outer wall of the second auxiliary gear (48) away from the main gear (42) meshes with the inner wall of the gear ring (41). A stirring element 2 (410) is fixedly connected to the lower middle part of the first auxiliary gear (47), and a stirring element 1 (49) is fixedly connected to the lower middle part of the second auxiliary gear (48). The first auxiliary gear (47) and the second auxiliary gear (48) are both located on the upper side of the rotating inner ring (46) and the fixed outer ring (27). The end of the stirring element 1 (49) near the second auxiliary gear (48) is located between the fixed outer ring (27) and the rotating inner ring (46), and the end of the stirring element 2 (410) near the first auxiliary gear (47) is located between the fixed outer ring (27) and the rotating inner ring (46). A fixed column (43) is fixedly connected to the upper middle part of the main gear (42), and a bevel gear four (44) is fixedly connected to the top of the fixed column (43). The fixed column (43) is located in the middle of the fixed sleeve (25). The bevel gear one (34) and the bevel gear four (44) mesh with each other. The agitator one (49) and the agitator two (410) are both located above the filter plate (29). The position of the fixed sleeve (25) corresponds to the position of the middle part of the top cover (5). Lift the support (31), pull the positioning block (326), connecting column (325) and sliding block (324), so that the sliding block (324) slides upward inside the cavity (322), so that bevel tooth one (34) disengages from bevel tooth four (44), bevel tooth two (35) disengages from bevel tooth three (38), and positioning block (326) disengages from the cavity (322). When the connecting column (325) is in the middle of the top of the cavity (322), the support (31) and its upper structure can be rotated, and the rotating rod (33) rotates away from the top cover (5). At this time, the top cover (5) can be opened to facilitate the subsequent injection of wastewater to be treated into the equipment. Then the support (31) and its upper structure are rotated back. Under the pull of the tension spring (327), the sliding block (324), the connecting column (325) and the positioning block (326) retract. The positioning block (326) is inserted into the top middle of the cavity (322). The bevel gear two (35) and the bevel gear three (38) re-engage. The positioning block (326) and the cavity (322) re-engage, which facilitates the operation of the subsequent equipment. Because the self-weight of the support (31) and its upper structure and the tension of the tension spring (327) work together, it can prevent the bevel gear two (35) and the bevel gear three (38), the positioning block (326) and the cavity (322) from disengaging from each other when the equipment is running.
