Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage and wastewater deep purification treatment device. Background Art

[0002] For environmental protection, the treatment of industrial wastewater is more important than the treatment of urban sewage. Industrial wastewater is usually divided into the following three types: The first is classified according to the chemical properties of the main pollutants contained in industrial wastewater. Wastewater containing mainly inorganic pollutants is inorganic wastewater, and wastewater containing mainly organic pollutants is organic wastewater. For example, electroplating wastewater and wastewater from mineral processing are inorganic wastewater; wastewater from food or petroleum processing is organic wastewater. The second is classified according to the products and processing objects of industrial enterprises, such as metallurgical wastewater, papermaking wastewater, coking coal gas wastewater, metal pickling wastewater, chemical fertilizer wastewater, textile printing and dyeing wastewater, dye wastewater, leather making wastewater, pesticide wastewater, power station wastewater, etc. The third is classified according to the main components of pollutants contained in wastewater, such as acidic wastewater, alkaline wastewater, cyanide-containing wastewater, chromium-containing wastewater, cadmium-containing wastewater, mercury-containing wastewater, phenol-containing wastewater, aldehyde-containing wastewater, oil-containing wastewater, sulfur-containing wastewater, organic phosphorus-containing wastewater and radioactive wastewater.

[0003] Among the existing authorized patents, the invention patent with patent number CN2019110366197 provides a method for deep purification of wastewater. The technical solution provided by the treatment method purifies wastewater by preparing a composite water treatment material. A certain proportion of pullulan, zeolite-loaded nano-titanium dioxide and modified bentonite are mixed to form a composite water treatment material, and the composite water treatment material is added to the wastewater treatment tank for stirring, static sedimentation and centrifugal separation to complete deep purification. After stirring, the wastewater and composite water treatment materials need to be statically precipitated. After the sedimentation is completed, the sedimentation tank forms an upper water body and a lower sediment. The upper water body can be pumped out and centrifuged to complete the water purification.

[0011] Furthermore, the articulated rod group includes a hinge rod and a movable rod, the hinge rod is hinged to the top of the sleeve, the upper end of the hinge rod is connected to the mounting frame via a frame rod, the frame rod is fixedly installed at the bottom of the mounting frame, the hinge rod and the frame rod are connected via a movable groove, the other end of the hinge rod is connected to one end of the movable rod, and the other end of the movable rod is hinged to the guide slide rod group.

[0012] Furthermore, the mixing and stirring treatment device includes a stirring tank, the top of which is provided with a feed inlet for feeding sewage and wastewater and composite water treatment materials, and the bottom of the stirring tank is provided with a screw conveying device for conveying the mixed water body of sewage and wastewater and composite water treatment materials to a sedimentation tank.

[0013] Furthermore, a sewage and wastewater deep purification treatment device includes the following implementation steps:

[0014] Step 1: Mix and stir the sewage and the composite water treatment material through a mixing and stirring treatment device, pump the sewage into a stirring tank, and add the composite water treatment material into the tank in a certain proportion to complete the mixing and stirring. After the stirring is completed, the mixed water of the sewage and the composite water treatment material is transported to the sedimentation tank by a screw conveying device;

[0015] Step 2: During static sedimentation, the mounting frame is in a raised state, and the mixed water of sewage and the composite water treatment material is statically precipitated in the sedimentation tank. At this time, the sewage outlet of the sedimentation tank is closed, and the mounting frame is lifted to lift the frame rod upward, and the frame rod drives the hinge rod to rotate, and the hinge rod drives the movable rod to move, so that the movable rod lifts the guide slide rod group upward, and then drives the connecting plate, the dirt baffle plate and the dirt guide plate to lift up, and the dirt baffle plate is used to seal the sewage outlet of the sedimentation tank;

[0016] Step 3: After the sedimentation is completed, the upper layer of water in the sedimentation tank is pumped out. When the scraping starts, the driving motor drives the cam to rotate, so that the proximal end of the cam abuts against the abutment wheel, and then the mounting frame rotates to a horizontal state. During the rotation of the mounting frame, the scraper plate gradually contacts the bottom of the sedimentation tank. When the mounting frame is flat, the cam continues to rotate, driving the connecting rod assembly and the plate frame and the scraper plate to move, so that the scraper plate gradually moves from the end of the stroke to the beginning of the stroke, completing the scraping of the sediment at the bottom of the sedimentation tank, and discharging the sediment from the sewage discharge device. After the scraping is completed, the distal end of the cam abuts against the abutment wheel again to lift the mounting frame and the scraper plate;

[0017] Step 4: When there is no need to scrape dirt, the distal end of the cam abuts against the abutment wheel, and the cam and the abutment wheel lift the mounting frame and the guide rod group and the scraper plate on the mounting frame, so that the scraper plate is lifted out of the sedimentation tank to prevent the scraper plate from being corroded by long-term contact with sewage when not in operation, and to facilitate cleaning of the scraper plate. At the same time, the connecting rod group pulls the plate frame and the scraper plate to the end of the guide rod group close to the cam, that is, the initial position of the scraper plate. As the cam continues to rotate, the cam will drive the connecting rod group to gradually push the scraper plate to the end of the guide rod group away from the cam, that is, the end of the travel of the scraper plate. In this process, the distal end of the cam is always abutted against the abutment wheel to keep the mounting frame and the scraper plate in a lifted state;

[0018] Step 5: When the mounting frame falls to a horizontal position, the frame rod pushes the hinge rod to rotate, and the hinge rod drives the movable rod to move downward, thereby pushing the guide slide rod group and the connecting plate downward. At the same time, the connecting plate pushes the dirt baffle plate and the dirt guide plate downward synchronously, and the dirt guide plate gradually aligns with the dirt outlet and connects. Then, the sediment is discharged from the dirt outlet under the scraping and pushing of the dirt scraper plate, and the sediment is discharged into the recovery pool or recovery and transfer equipment by using the dirt guide plate.

DETAILED DESCRIPTION

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] like Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0031] A sewage and wastewater deep purification treatment equipment comprises: a mixing and stirring treatment device 1 for mixing sewage and wastewater with a composite water quality treatment material and a sedimentation tank 2 for static sedimentation after the sewage and wastewater and the composite water quality treatment material are mixed, a cleaning device 3 for cleaning the sediment is arranged above the sedimentation tank 2, the mixing and stirring treatment device 1 is arranged on one side of the sedimentation tank 2, the cleaning device 3 is installed at the upper end of the sedimentation tank 2, and a sewage discharge device 4 for facilitating the discharge of sediment is arranged at one end of the sedimentation tank 2 away from the mixing and stirring treatment device 1.

[0032] Specifically, in order to solve the technical problems of mixing, stirring, standing and cleaning sediments after sedimentation of sewage and wastewater and composite water treatment materials during sewage and wastewater purification, the present invention mixes and stirs sewage and wastewater with composite water treatment materials through a mixing and stirring treatment device 1, and discharges the mixed water body after stirring into a sedimentation tank 2 for standing, waiting for natural sedimentation, and after the sedimentation is completed, the upper water body is pumped out, and the sediments in the lower layer are discharged from the sewage discharge device 4 by the cleaning device 3, so as to clean the sedimentation tank 2. The present invention uses composite water treatment materials to deeply purify sewage and wastewater, completes the preliminary separation of water and sewage in the sedimentation tank 2, and can effectively recover the sediment for reprocessing.

[0033] like Figures 2 to 5 As shown, the following preferred technical solutions are provided:

[0034] The cleaning device 3 includes a scraper plate 31, a guide rod group 32 and a driving connecting rod assembly 33. The scraper plate 31 is installed on the guide rod group 32 through a plate frame 34. The plate frame 34 is pushed by the driving connecting rod assembly 33 to reciprocate on the guide rod group 32. The scraper plate 31 is fixed to the lower end of the plate frame 34, and the plate frame 34 is slidably installed on the guide rod group 32. The guide rod group 32 is installed above one side of the sedimentation tank 2 through a mounting frame 35, and the mounting frame 35 is hinged to one side of the sedimentation tank 2 through a bracket 36.

[0035] The driving connecting rod assembly 33 includes a driving motor 331, a cam 332 and a connecting rod group 333. One end of the connecting rod group 333 is hinged to the plate frame 34, and the other end is fixedly connected to the cam 332. The driving motor 331 is installed on the mounting frame 35. The output end of the driving motor 331 is connected to the cam 332. The cam 332 and the bracket 36 are abutted through the abutment wheel 334.

[0036] Specifically, in order to solve the technical problem of scraping off the sediment in the sedimentation tank 2, the present invention drives the cam 332 and the connecting rod group 333 to move by driving the motor 331, thereby pushing the plate frame 34 connected to the connecting rod group 333 and the scraping plate 31 to move along the guide rod group 32. At the same time, because the cam 332 abuts against the abutment wheel 334 on the lower bracket 36, the mounting frame 35 changes its angle with the bracket 36 according to the rotation position of the cam 332 during the rotation of the cam 332.

[0037] When the scraping is not needed, the distal end of the cam 332 abuts against the abutting wheel 334, and the cam 332 and the abutting wheel 334 lift the mounting frame 35 and the guide rod group 32 and the scraper plate 31 on the mounting frame 35, so that the scraper plate 31 is lifted out of the sedimentation tank 2, thereby preventing the scraper plate 31 from being corroded by contacting the sewage for a long time when not in operation, and also facilitating the cleaning of the scraper plate 31. At the same time, the connecting rod group 333 pulls the plate frame 34 and the scraper plate 31 to the end of the guide rod group 32 close to the cam 332, that is, the initial position of the scraper plate 31. As the cam 332 continues to rotate, the cam 332 drives the connecting rod group 333 to gradually push the scraper plate 31 to the end of the guide rod group 32 away from the cam 332, that is, the end of the stroke of the scraper plate 31. In this process, the distal end of the cam 332 always abuts against the abutting wheel 334, keeping the mounting frame 35 and the scraper plate 31 in a lifted state;

[0038] When scraping begins, the cam 332 rotates so that the proximal end of the cam 332 abuts against the abutment wheel 334, and then the mounting frame 35 rotates to a horizontal state. During the rotation of the mounting frame 35, the scraping plate 31 gradually contacts the bottom of the sedimentation tank 2. When the mounting frame 35 turns flat, the cam 332 continues to rotate, driving the connecting rod group 333 and the plate frame 34 and the scraping plate 31 to move, so that the scraping plate 31 gradually moves from the end of the stroke to the beginning of the stroke, completing the scraping of the sediment at the bottom of the sedimentation tank 2 and discharging the sediment from the sewage discharge device 4. After the scraping is completed, the distal end of the cam 332 abuts against the abutment wheel 334 again to lift the mounting frame 35 and the scraping plate 31.

[0039] like Figure 6 and Figure 7 As shown, the following preferred technical solutions are provided:

[0040] The sewage discharge device 4 includes a sewage guide plate 41, a guide slide assembly 42 and a fixed plate 43. The sewage guide plate 41 is installed on the guide slide assembly 42. The sewage guide plate 41 is slidably connected to the sewage outlet of the sedimentation tank 2. The guide slide assembly 42 is installed on the fixed plate 43. The fixed plate 43 is fixedly installed on the sedimentation tank 2. The guide slide assembly 42 is connected to the mounting frame 35 through a hinged rod group 44. A sewage baffle plate 45 is provided at the lower end of the sewage guide plate 41.

[0041] The guide slide assembly 42 includes a connecting plate 421, a guide slide rod group 422 and a guide rod sleeve 423. The connecting plate 421 is fixedly installed at the bottom of the guide slide rod group 422. The dirt baffle plate 45 is fixedly connected to the connecting plate 421. The guide slide rod group 422 is slidably connected to the guide rod sleeve 423. The guide rod sleeve 423 and the fixed plate 43 are connected through a sleeve seat 424. The guide rod sleeve 423 is fixedly installed at the bottom of the sleeve seat 424. The top of the guide slide rod group 422 is connected to the hinged rod group 44. The hinged rod group 44 is hinged at the top of the sleeve seat 424. A buffer spring 425 is arranged between the guide rod sleeve 423 and the connecting plate 421. The buffer spring 425 is sleeved on the guide slide rod group 422. The top of the guide slide rod group 422 and the fixed plate 43 are connected through a tension spring 426.

[0042] The hinged rod group 44 includes a hinge rod 441 and a movable rod 442. The hinge rod 441 is hinged to the top of the sleeve 424. The upper end of the hinge rod 441 is connected to the mounting frame 35 via a frame rod 443. The frame rod 443 is fixedly installed at the bottom of the mounting frame 35. The hinge rod 441 and the frame rod 443 are connected via a movable groove 444. The other end of the hinge rod 441 is connected to one end of the movable rod 442. The other end of the movable rod 442 is hinged to the guide slide rod group 422.

[0043] Specifically, in order to solve the technical problems of opening and closing the sewage outlet of the sedimentation tank 2 and facilitating the discharge of sediment, the present invention realizes the opening and closing of the sewage outlet of the sedimentation tank 2 by changing the position state between the mounting frame 35 and the sedimentation tank 2, and changes the rotation state of the mounting frame 35 by the rotation of the cam 332. When the mounting frame 35 is lifted, the mixed water body of sewage and wastewater and the composite water treatment material is statically precipitated in the sedimentation tank 2. At this time, the sewage outlet of the sedimentation tank 2 is closed, and the mounting frame 35 is lifted to lift the frame rod 443 upward. The frame rod 443 drives the hinge rod 441 to rotate, and the hinge rod 441 drives the movable rod 442 to move, so that the movable rod 442 lifts the guide slide rod group 422, thereby driving the connecting plate 421 and the dirt baffle plate 45 and the dirt guide plate 41 to lift up, and the sewage outlet of the sedimentation tank 2 is sealed and blocked by the dirt baffle plate 45;

[0044] When the mounting frame 35 falls to a horizontal position, the frame rod 443 pushes the hinge rod 441 to rotate, and the hinge rod 441 drives the movable rod 442 to move downward, thereby pushing the guide slide rod group 422 and the connecting plate 421 downward. At the same time, the connecting plate 421 pushes the dirt baffle plate 45 and the dirt guide plate 41 downward synchronously, and the dirt guide plate 41 gradually aligns with the dirt outlet and connects. Then, the sediment is discharged from the dirt outlet under the scraping and pushing of the dirt scraper plate 31, and the sediment is discharged into the recovery pool or the recovery and transfer equipment by using the dirt guide plate 41.

[0045] like Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

After the mixing is completed, the mixed water of the wastewater and the composite water treatment material is transported to the sedimentation tank 2 by the screw conveying device 12;

[0051] Step 2: During static sedimentation, the mounting frame 35 is in a raised state, and the mixed water body of sewage and wastewater and the composite water treatment material is statically precipitated in the sedimentation tank 2. At this time, the sewage outlet of the sedimentation tank 2 is closed, and the mounting frame 35 is lifted to lift the frame rod 443 upward, and the frame rod 443 drives the hinge rod 441 to rotate, and the hinge rod 441 drives the movable rod 442 to move, so that the movable rod 442 lifts the guide slide rod group 422, and then drives the connecting plate 421 and the dirt baffle plate 45 and the dirt guide plate 41 to lift up, and the dirt baffle plate 45 is used to seal the sewage outlet of the sedimentation tank 2;

[0052] Step 3: After the sedimentation is completed, the upper layer of water in the sedimentation tank 2 is pumped out. When scraping begins, the driving motor 331 drives the cam 332 to rotate, so that the proximal end of the cam 332 abuts against the abutment wheel 334, and then the mounting frame 35 rotates to a horizontal state. During the rotation of the mounting frame 35, the scraping plate 31 gradually contacts the bottom of the sedimentation tank 2. When the mounting frame 35 is flat, the cam 332 continues to rotate, driving the connecting rod group 333 and the plate frame 34 and the scraping plate 31 to move, so that the scraping plate 31 gradually moves from the end of the stroke to the beginning of the stroke, completing the scraping of the sediment at the bottom of the sedimentation tank 2, and discharging the sediment from the sewage discharge device 4. After the scraping is completed, the distal end of the cam 332 abuts against the abutment wheel 334 again to lift the mounting frame 35 and the scraping plate 31;

[0054] Step 5: When the mounting frame 35 falls to a horizontal position, the frame rod 443 pushes the hinge rod 441 to rotate, and the hinge rod 441 drives the movable rod 442 to move downward, thereby pushing the guide slide rod group 422 and the connecting plate 421 downward, and at the same time, the connecting plate 421 pushes the dirt baffle plate 45 and the dirt guide plate 41 downward synchronously, and the dirt guide plate 41 gradually aligns with the dirt outlet and connects, and then the sediment is discharged from the dirt outlet under the scraping and pushing of the dirt scraper plate 31, and the sediment is discharged to the recovery pool or recovery and transfer equipment by using the dirt guide plate 41.
