Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an integrated wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] Current wastewater treatment methods primarily involve removing debris and fine impurities. This typically involves filtering and intercepting debris through a filter screen, then adding flocculants and mixing the wastewater to adsorb and remove fine impurities. Finally, the treated wastewater undergoes further impurity separation. This method requires multiple devices—preliminary filtration, mixing, and secondary filtration—to effectively remove debris and fine impurities, necessitating multiple wastewater transfers and reducing treatment efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides an integrated wastewater treatment device.

[0005] The technical solution is as follows: An integrated wastewater treatment device includes a mixing tank, with legs fixedly connected to the bottom of the mixing tank, a collection tank embedded in the top of the mixing tank, a filter screen inclinedly connected to the upper part of the collection tank, a circular groove formed in the lower part of the collection tank, a shaft rotatably connected to the lower part of the collection tank, first blades evenly distributed circumferentially fixed to the outer side of the shaft, the first blades being located within the circular groove, a discharge port formed on the side wall of the collection tank, a sliding groove formed on the collection tank above the discharge port, and a baffle slidably connected within the sliding groove. The bottom of the baffle is in sealed contact with the bottom of the discharge port. A symmetrically distributed stirring paddle is rotatably connected to the mixing tank. The float is located between two stirring paddles. A reduction motor is mounted on the side wall of the mixing tank via a bracket. The reduction motor is connected to one of the stirring paddles on one side. The symmetrically distributed stirring paddles are driven by a gear set. A discharge port is opened at the bottom of the mixing tank. An electromagnetic valve is installed in the discharge port. A proportioning component for discharging flocculant is provided on one side of the top of the mixing tank. The proportioning component is connected to the other end of the shaft.

[0006] Furthermore, the proportioning component includes a container embedded on one side of the top of the mixing tank. The lower part of the container has symmetrically distributed fixed blocks. A symmetrically distributed rotating rod is rotatably connected to the container. A second blade is fixedly connected to the outer side of the rotating rod in a circumferentially equidistant manner. The second blade is located between the symmetrically distributed fixed blocks. A pulley is fixedly connected to the end of the rotating rod. A double-groove pulley is fixedly connected to the other end of the shaft. The double-groove pulley and the pulley are connected by a belt drive.

[0007] Furthermore, the symmetrically distributed fixing blocks cooperate to form a circular groove, and the top of the fixing blocks is an inclined surface to facilitate the sliding of flocculant.

[0008] Furthermore, the transmission ratio of the double-groove pulley is proportional to that of the belt pulley.

[0009] Furthermore, a disc is fixed to one end of the shaft, a pin is fixed to the eccentric position of the side wall of the disc, a hollow frame is slidably connected to the outside of the pin, a slide rod is fixed to the top of the hollow frame, the slide rod passes through the collection box and is slidably sealed thereto, and a collision ball is fixed to the top of the slide rod.

[0010] Furthermore, the collision ball is made of elastic rubber material.

[0011] Furthermore, the mixing tank is equipped with a float plate, and a movable plate is fixedly connected to the top of the float plate. A locking groove is opened on the side wall of the movable plate. A sliding hole is opened on the mixing tank. A locking block is connected to the sliding hole through a support spring. The end of the locking block is a rotating ball. The rotating ball contacts and engages with the side wall of the movable plate. The movable plate passes through the top of the mixing tank and is slidably and sealingly connected to it. A push frame is fixedly connected to the top of the movable plate. The push frame is located directly below the baffle.

[0012] Furthermore, the cross-section of the upper part of the push frame is an equilateral triangle structure.

[0013] Furthermore, a fixed frame is fixedly connected to the bottom of the mixing box. The fixed frame has an opening communicating with the discharge port. The fixed frame has symmetrically distributed transverse grooves. Symmetrically distributed straight racks are connected to the fixed frame. A sliding frame is slidably connected to the inner side of the fixed frame. Discharge shells are fixedly connected to both sides of the sliding frame. An intercepting net is connected to each discharge shell through a connecting shaft. The connecting shaft is located in the corresponding transverse groove. A spur gear is fixedly connected to the end of the connecting shaft. Symmetrically distributed connecting rods are fixedly connected to the bottom of the mixing box. A drainage shell is fixedly connected between the lower ends of the symmetrically distributed connecting rods. Symmetrically distributed moving grooves are opened on the fixed frame. Symmetrically distributed fixed rods are fixedly connected to the sliding frame. The fixed rods pass through adjacent moving grooves. Symmetrically distributed electric push rods are fixedly connected to the fixed frame. The telescopic end of the electric push rod is connected to the adjacent fixed rod.

[0014] Furthermore, the symmetrically distributed interception nets face opposite directions.

[0015] The beneficial effects of this invention are: 1. This invention uses a filter screen to intercept debris in wastewater. Because the filter screen is tilted, the debris on the screen slides down the tilted surface to a lower position. The water flow impacts the first blade, which drives the shaft to rotate the disc. The rotation of the disc drives the pin on it to move the hollow frame up and down. The up and down movement of the hollow frame, through the sliding rod, causes the collision ball to move up and down to collide with the filter screen, making the filter screen shake. This accelerates the sliding of the intercepted debris to a lower position, preventing the debris from clogging the filter screen and affecting the wastewater filtration efficiency.

[0016] 2. The shaft rotates, and through the double-groove pulley and belt pulley, the belt pulley drives the second blade to rotate via the rotating rod. The rotation of the second blade conveys the flocculant in the container box downwards into the mixing box. The operation of the geared motor causes the two agitators to rotate in different directions, creating convection in the mixing box to accelerate the mixing efficiency of the wastewater with the flocculant. This speeds up the adsorption of fine impurities in the wastewater by the flocculant, making it easier to clean up the fine impurities in the wastewater.

[0017] 3. The float plate moves upward as the liquid level rises. The upward movement of the float plate causes the pusher frame to move upward, which in turn pushes the baffle plate upward. The upward movement of the baffle plate opens the discharge port, allowing the debris trapped on the filter screen to be discharged. Attached Figure Description

Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings.

[0031] An integrated wastewater treatment device, such as Figure 1-11As shown, the system includes a mixing tank 1, with four support legs 2 fixed to the bottom. A collection tank 3 is embedded in the top of the mixing tank 1. A filter screen 4 is inclinedly connected to the upper part of the collection tank 3, with the filter screen 4 tilted to the left and lowered to the right. A circular groove 5 is opened in the lower part of the collection tank 3. A shaft 6 is rotatably connected to the lower part of the collection tank 3. First blades 7, evenly distributed in a circumferential direction, are fixed to the outer side of the shaft 6 and are located in the circular groove 5. A discharge port 16 is opened on the side wall of the collection tank 3. A sliding groove 17 is opened on the collection tank 3 above the discharge port 16. A baffle 18 is slidably connected in the sliding groove 17. The bottom of the baffle 18 is in sealing contact with the bottom of the discharge port 16. Two stirring paddles 19 are rotatably connected to the mixing tank 1 and are symmetrically distributed in a front-to-back manner. A float 13 is located between the two stirring paddles 19. A geared motor 20 is mounted on the left side wall of the mixing tank 1 via a bracket. The geared motor 20 is connected to the left end of the rear stirring paddle 19. The two stirring paddles 19 are driven by a gear set 21. A discharge port 22 is provided at the bottom of the mixing tank 1, and an electromagnetic valve is provided inside the discharge port 22. A proportioning component for discharging flocculant is provided on the left side of the top of the mixing tank 1. The proportioning component is connected to the left end of the shaft 6. The geared motor 20 drives the stirring paddle 19 connected to it. The rotation of the stirring paddle 19 can cause the other stirring paddle 19 to rotate through the gear set 21. The two stirring paddles 19 rotate in different directions, which can make the sewage in the mixing tank 1 form convection to accelerate the mixing efficiency with the flocculant. This can speed up the adsorption of fine impurities in the sewage by the flocculant, making it easier to clean the fine impurities in the sewage.

[0032] The proportioning component includes a container 23 embedded in the top left side of the mixing tank 1. The lower part of the container 23 has four fixing blocks 24, arranged in pairs and symmetrically distributed front to back. Two adjacent fixing blocks 24 cooperate to form a circular groove, and the top of the fixing blocks 24 is inclined to facilitate the sliding of flocculant. Two rotating rods 25 symmetrically distributed front to back are rotatably connected to the container 23. Second blades 26, circumferentially equidistant, are fixed to the outer side of the rotating rods 25, located between adjacent fixing blocks 24. A pulley 27 is fixed to the right end of the rotating rod 25. The shaft 6... A double-groove pulley 28 is fixed to the left end. The double-groove pulley 28 and the belt pulley 27 are connected by belt drive. The transmission ratio of the double-groove pulley 28 and the belt pulley 27 is proportional. The rotation of the shaft 6 can cause the double-groove pulley 28 on it to rotate. The rotation of the double-groove pulley 28 can cause the belt pulley 27 to rotate. The rotation of the belt pulley 27 can cause the second blade 26 to rotate through the rotating rod 25. The rotation of the second blade 26 can transport the flocculant in the holding box 23 downward into the mixing box 1, which is convenient for stirring and mixing the sewage and can avoid the sewage treatment being affected by too much or too little flocculant.

[0033] A disc 8 is fixed to the right end of the shaft 6. A pin 9 is fixed to the eccentric position of the side wall of the disc 8. A hollow frame 10 is slidably connected to the outside of the pin 9. A slide rod 11 is fixed to the top of the hollow frame 10. The slide rod 11 passes through the collection box 3 and is slidably connected to it in a sealed manner. A collision ball 12 is fixed to the top of the slide rod 11. The collision ball 12 is made of elastic rubber. The filtered sewage flows downward and impacts the first blade 7, causing the shaft 6 to rotate and flow into the mixing box 1. The rotation of the shaft 6 can cause the pin 9 on it to move circumferentially through the disc 8. During the circumferential movement of the pin 9, the hollow frame 10 can move up and down. The up and down movement of the hollow frame 10 can cause the collision ball 12 to move up and down through the slide rod 11 to collide with the filter screen 4, causing the filter screen 4 to shake. This accelerates the sliding of the debris intercepted on it to a lower position, preventing the debris from clogging the filter screen 4 and thus affecting the filtration efficiency of the sewage.

[0034] A float plate 13 is provided inside the mixing tank 1. A movable plate 14 is fixedly connected to the top of the float plate 13. A locking groove 141 is opened on the side wall of the movable plate 14. A sliding hole is opened on the mixing tank 1. A locking block 142 is connected to the sliding hole of the mixing tank 1 through a support spring 143. The end of the locking block 142 is a rotating ball. The rotating ball on the locking block 142 contacts and engages with the side wall of the movable plate 14. The rotating ball on the locking block 142 is located on the moving trajectory of the locking groove 141. The movable plate 14 passes through the top of the mixing tank 1 and is slidably sealed to it. Next, a pusher frame 15 is fixed to the top of the moving plate 14. The upper cross section of the pusher frame 15 is an equilateral triangle structure, and the apex of the equilateral triangle faces one side of the collection box 3. The pusher frame 15 is located directly below the baffle 18. The float 13 will move upward as the liquid level rises. The upward movement of the float 13 causes the pusher frame 15 to move upward through the moving plate 14. The upward movement of the pusher frame 15 pushes the baffle 18 to move upward. The upward movement of the baffle 18 opens the discharge port 16. After the discharge port 16 is opened, the debris intercepted on the filter screen 4 is discharged through it.

[0035] A fixed frame 29 is fixedly connected to the bottom of the mixing box 1. The fixed frame 29 has an opening communicating with the discharge port 22. Symmetrically distributed transverse grooves 30 are provided on the fixed frame 29. Symmetrically arranged straight racks 31 are connected to the fixed frame 29. A sliding frame 32 is slidably connected to the inner side of the fixed frame 29. Discharge shells 33 are fixedly connected to both sides of the sliding frame 32. Each discharge shell 33 is connected to an intercepting net 34 via a connecting shaft. The two intercepting nets 34 face opposite directions. The connecting shafts are located within the corresponding transverse grooves 30. A spur gear 35 is fixedly connected to the end of the connecting shaft. Symmetrically distributed connecting rods 36 are fixedly connected to the bottom of the mixing box 1. A drain shell 37 is fixedly connected between the lower ends of the symmetrically distributed connecting rods 36. Symmetrically distributed moving grooves 38 are provided on the fixed frame 29. Symmetrically distributed fixed rods 39 are fixedly connected to the sliding frame 32. The fixed rods 39 pass through adjacent moving grooves. The moving groove 38 and the fixed frame 29 are fixedly connected to symmetrically distributed electric push rods 40. The telescopic end of the electric push rod 40 is connected to the adjacent fixed rod 39. The electric push rod 40 is periodically activated to move the sliding frame 32 to one side through the fixed rod 39. The movement of the sliding frame 32 can move the discharge shell 33 on it. After the spur gear 35 and the rack 31 are engaged, the sliding frame 32 continues to move. This allows the discharge shell 33 on one side to gradually move away from the opening and drainage shell 37 on the fixed frame 29. The spur gear 35 and the rack 31 are engaged to rotate the intercepting net 34 through the connecting shaft. When the sliding frame 32 moves to one side and is limited by the transverse groove 30 through the connecting shaft, the intercepting net 34 rotates 180° and flips over. This allows the debris intercepted in the intercepting net 34 to be poured out. At this time, the other discharge shell 33 is engaged with the opening and drainage shell 37 on the fixed frame 29.

[0036] During use, the user first pours the flocculant into the holding tank 23. When treating wastewater, the user pumps the wastewater to the collection tank 3 using an external pump. Impurities in the wastewater falling into the collection tank 3 are intercepted by the filter screen 4. Because the filter screen 4 is tilted, the intercepted impurities slide down its inclined surface to a lower position. The filtered wastewater flows downwards, impacting the first blade 7, which drives the shaft 6 to rotate and flows into the mixing tank 1. The rotation of the shaft 6, through the disc 8, causes the pin 9 on it to move circumferentially. During this circumferential movement, the pin 9 causes the hollow frame 10 to move up and down. The up-and-down movement of the hollow frame 10... The sliding rod 11 causes the collision ball 12 to move up and down, colliding with the filter screen 4 and causing it to shake. This accelerates the sliding of debris intercepted on the screen, preventing it from clogging the filter screen and affecting the filtration efficiency of the wastewater. The rotation of the shaft 6 causes the double-groove pulley 28 to rotate. The rotation of the double-groove pulley 28, via a belt, causes the pulley 27 to rotate. The rotation of the pulley 27, via the rotating rod 25, causes the second blade 26 to rotate. The rotation of the second blade 26 conveys the flocculant in the container 23 downwards into the mixing tank 1. As the wastewater level in the mixing tank 1 rises, the float 13 moves with the water level. The float 13 moves upward, causing the pusher 15 to move upward via the moving plate 14. During this process, when the moving plate 14 moves upward and its locking groove 141 aligns with the locking block 142, the rotating ball on the locking block 142 can be engaged into the locking groove 141 under the action of the support spring 143, thus fixing the moving plate 14. This prevents the float 13 from moving up and down unpredictably due to liquid collisions causing unstable liquid levels during subsequent liquid convection in the mixing tank 1. After the sewage treatment is completed, the user can manually reset the pusher 15, which then moves upward to push the baffle 18. The baffle 18 moves upward, opening the discharge port 16. After the discharge port 16 opens, the debris intercepted on the filter screen 4 is discharged through it. At this time, the external pump body stops pumping sewage and starts the geared motor 20. The geared motor 20 drives the agitator 19 connected to it. The rotation of the agitator 19, through the gear set 21, enables the other agitator 19 to rotate. The two agitators 19 rotate in different directions, which can make the sewage in the mixing tank 1 form convection to accelerate the mixing efficiency with the flocculant. This can speed up the adsorption of fine impurities in the sewage by the flocculant, making it easier to clean the fine impurities in the sewage.

[0037] After cleaning the fine impurities in the wastewater, the operator turns off the reduction motor 20 and starts the solenoid valve to open the discharge port 22. The treated wastewater in the mixing tank 1 flows downward through the discharge port 22 and the opening on the fixed frame 29. The wastewater is filtered by the interception net 34, which intercepts the accumulated debris. The wastewater passes through the interception net 34 and is discharged through the discharge shell 33. The electric push rod 40 is periodically activated to move the sliding frame 32 to one side via the fixed rod 39. The movement of the sliding frame 32 moves the discharge shell 33 on it. After the spur gear 35 engages with the rack 31, the sliding frame 32 continues to move, which allows the discharge shell 33 on one side to gradually move away from the opening and drainage shell 37 on the fixed frame 29. The spur gear 35 and the rack 31 engage through the connecting shaft to rotate the intercepting net 34. When the sliding frame 32 moves to one side and is limited by the transverse groove 30 through the connecting shaft, the intercepting net 34 rotates 180° and flips over, which allows the debris intercepted in the intercepting net 34 to be poured out. At this time, the other discharge shell 33 engages with the opening and drainage shell 37 on the fixed frame 29.

[0038] The above operations eliminate the need for multiple devices to treat wastewater and the need for multiple transfers, thereby improving the efficiency of wastewater treatment.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
