Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an advanced oxidation deep treatment wastewater device. Background Technology

[0002] Wastewater oxidation treatment is a type of wastewater chemical treatment method. It uses strong oxidants to oxidize and decompose pollutants in wastewater in order to purify the wastewater. Strong oxidants can gradually degrade organic matter in wastewater into simple inorganic matter, and can also oxidize pollutants dissolved in water into substances that are insoluble in water and easy to separate from the water. Oxidation treatment can treat almost all industrial wastewater.

[0003] When treating wastewater through oxidation, if the suspended solids content in the wastewater is high, it is generally necessary to first remove large particles (such as paper, plastic, branches, etc.) from the wastewater through a screen, then remove suspended solids through physical methods (such as sedimentation and filtration) or chemical methods (such as adding coagulants), and finally filter the wastewater through a gravity filter to improve the efficiency of subsequent wastewater treatment.

[0004] Currently, when treating suspended solids in wastewater, large particles tend to accumulate on the surface of the grid. Due to the large size of the grid openings at the inlet, some particles can seep into the treatment tank through the gaps and then remix with the wastewater. After the coagulant removes the suspended solids, they accumulate on the surface of the gravity filter when the wastewater is discharged, thus reducing the efficiency of wastewater infiltration. Utility Model Content

[0005] The purpose of this invention is to provide an advanced oxidation deep treatment wastewater equipment to solve the problem mentioned in the background art: when treating suspended solids in wastewater, large particles tend to accumulate on the grid surface. Due to the large size of the grid holes at the inlet, some particles will seep into the treatment tank through the gaps and then remix with the wastewater. After the suspended solids are treated by the coagulant, they will accumulate on the surface of the gravity filter when the wastewater is discharged, thereby reducing the efficiency of wastewater infiltration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an advanced oxidation deep treatment wastewater device, comprising a treatment tank, a grid disposed inside the treatment tank, and a gravity filter connected inside the treatment tank;

[0007] The processing box is connected to a support frame inside, and a filter screen is slidably connected inside the support frame. The processing box is equipped with a drive mechanism to drive the filter screen to rise and fall.

[0008] The processing box is internally connected to two support rods, and the two support rods are rotatably connected to a stirring rod. A driving component is provided on the outside of the stirring rod.

[0009] The inner wall of the processing tank is connected to a second filter screen, and multiple scrapers are slidably connected to the top of the second filter screen. The bottom of the stirring rod is provided with an active mechanism to drive the multiple scrapers to move laterally.

[0010] Preferably, the drive mechanism includes a motor, a rotating rod, and a cam;

[0011] A motor is connected to the outer wall of the processing box. A rotating rod is sleeved on the output end of the motor. The other end of the rotating rod is rotatably connected to the inner wall of the processing box. A cam is sleeved on the outer wall of the rotating rod. The top of the cam is attached to one bottom end of the filter screen.

[0012] Preferably, the support frame is internally connected to multiple uprights, each of which is slidably connected inside the filter screen.

[0013] Preferably, the diameter of the slot inside the support frame is larger than the diameter of the slot inside the grid.

[0014] Preferably, the driving component includes a first conical tooth and a second conical tooth;

[0015] The outer wall of the stirring rod is fitted with a conical tooth one, and the outer wall of the conical tooth one is engaged with a conical tooth two, which is fitted onto the outer wall of the rotating rod.

[0016] Preferably, the moving mechanism includes a gear and a gear ring;

[0017] The bottom end of the stirring rod is connected to a gear, and a gear ring meshes with the outer wall of the gear. Multiple scrapers are connected to the bottom end of the gear ring, and the top end of the gear ring is slidably connected to the bottom end of any of the support rods.

[0018] Preferably, the processing box is internally connected to two sliding rods, both of which are slidably connected inside the plurality of scrapers.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By driving the filter screen to rise and fall inside the support frame, the filter screen hits the grid during the rising and falling process, causing the grid and filter screen to vibrate. This causes the blockage to slightly separate from the surface of the grid and filter screen, allowing the wastewater to seep into the treatment tank through the grid and filter screen, thereby reducing the occurrence of blockage. In conjunction with the filter screen, it can further reduce large particulate matter in the wastewater that seeps into the treatment tank.

[0021] 2. The driving component drives the stirring rod to rotate, allowing the coagulant to mix thoroughly with the wastewater inside the treatment tank. Simultaneously, the stirring rod drives the gear to rotate, which in turn causes the gear ring to move multiple scrapers back and forth across the surface of the second filter screen to scrape off suspended solids. This allows the wastewater to quickly seep through the second filter screen into the gravity filter, where it is filtered until it is discharged, thus improving the efficiency of wastewater infiltration.

[0027] 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 protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a technical solution: an advanced oxidation deep treatment wastewater device, including a treatment tank 1, a grid 101 installed inside the treatment tank 1, and a gravity filter 102 connected inside the treatment tank 1; a drain outlet is provided at the bottom of the treatment tank 1.

[0029] A support frame 2 is connected inside the treatment tank 1. A filter screen 201 is slidably connected inside the support frame 2. A drive mechanism is provided inside the treatment tank 1 to drive the filter screen 201 to rise and fall. When wastewater is poured into the treatment tank 1, some large particles fall through the grid 101 onto the surface of the filter screen 201. The drive mechanism drives the filter screen 201 to rise and fall inside the support frame 2, causing the filter screen 201 to collide with the grid 101 during the rising and falling process. This causes the grid 101 and the filter screen 201 to vibrate, resulting in slight separation of the blockage from the surface of the grid 101 and the filter screen 201. This allows the wastewater to seep into the treatment tank 1 through the grid 101 and the filter screen 201, thereby reducing the occurrence of blockage. The filter screen 201 can further reduce the large particles in the wastewater that seep into the treatment tank 1.

[0030] The treatment tank 1 is connected to two support rods 301, and the two support rods 301 are rotatably connected to a stirring rod 3. A driving component is provided on the outside of the stirring rod 3. The driving component drives the stirring rod 3 to rotate inside the two support rods 301, thereby enabling the coagulant to be fully mixed with the wastewater inside the treatment tank 1, thereby increasing the formation of suspended solids.

[0031] The inner wall of the treatment tank 1 is connected to a filter screen 4. Multiple scrapers 401 are slidably connected to the top of the filter screen 4. The bottom of the stirring rod 3 is provided with an active mechanism to drive the multiple scrapers 401 to move laterally. By driving the scrapers 401 to move laterally through the active mechanism, the suspended matter deposited on the surface of the filter screen 4 can be scraped off, thereby improving the efficiency of wastewater infiltration.

[0032] The drive mechanism includes a motor, a rotating rod 203, and a cam 204;

[0033] A motor is connected to the outer wall of the treatment box 1. A rotating rod 203 is sleeved on the output end of the motor. The other end of the rotating rod 203 is rotatably connected to the inner wall of the treatment box 1. A cam 204 is sleeved on the outer wall of the rotating rod 203. The top of the cam 204 is attached to the bottom of the filter screen 201. The rotating rod 203 is driven to rotate by the motor, which causes the rotating rod 203 to drive the cam 204 to rotate, so that the cam 204 intermittently squeezes the filter screen 201, causing the filter screen 201 to intermittently rise and fall inside the support frame 2.

[0034] Multiple uprights 202 are connected inside the support frame 2, and each upright 202 is slidably connected inside the filter screen 201. By sliding the filter screen 201 outside the uprights 202 during the lifting and lowering process, the stability of the filter screen 201 during the lifting and lowering process can be improved, and the filter screen 201 can be prevented from tilting.

[0035] The diameter of the inner groove of the support frame 2 is larger than the diameter of the inner groove of the grid 101. After the filter screen 201 is lowered, the bottom end of the filter screen 201 can fit against the inner wall of the upright 202, which can provide better support for the filter screen 201 and reduce the deformation caused by excessive large particles on the surface of the filter screen 201.

[0036] The drive component includes bevel tooth 302 and bevel tooth 303;

[0037] The outer wall of the stirring rod 3 is fitted with a conical tooth 302, and the outer wall of the conical tooth 302 is engaged with a conical tooth 303. The conical tooth 303 is fitted on the outer wall of the rotating rod 203. The rotation of the rotating rod 203 drives the conical tooth 303 to rotate, which in turn causes the conical tooth 302 engaged with the conical tooth 303 to drive the stirring rod 3 to rotate on the support rod 301, thereby causing the stirring rod 3 to stir the wastewater and coagulant inside the treatment tank 1.

[0038] The moving mechanism includes gear 403 and gear ring 404;

[0039] A gear 403 is connected to the bottom end of the stirring rod 3. A gear ring 404 meshes with the outer wall of the gear 403. Multiple scrapers 401 are connected to the bottom end of the gear ring 404. The top end of the gear ring 404 is slidably connected to the bottom end of any support rod 301. The rotation of the stirring rod 3 drives the gear 403 to rotate synchronously, causing the gear ring 404 meshing with the gear 403 to reciprocate at the bottom end of the support rod 301. This causes the gear ring 404 to drive multiple scrapers 401 to reciprocate on the surface of the gravity filter 102, thereby scraping away suspended matter deposited on the surface of the filter screen 4. This allows wastewater to quickly seep through the filter screen 4 into the interior of the gravity filter 102, where it is filtered until it is discharged.

[0040] The processing box 1 is internally connected to two sliding rods 402, both of which are slidably connected to multiple scrapers 401. The scrapers 401 slide on the outer wall of the sliding rods 402 during the reciprocating lateral movement, thereby maintaining the stability of the scrapers 401 during the lateral movement.

[0041] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
