Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment agent post-treatment and impurity removal device. Background Technology

[0002] Post-treatment of wastewater is an important part of the wastewater treatment process. Its core is to further purify the wastewater after chemical treatment to ensure that the water quality meets the discharge or reuse standards. The post-treatment impurity removal device can coagulate fine particles and organic matter in the wastewater into larger particles by the chemical treatment, which is convenient for subsequent sedimentation and separation, and remove the impurities formed.

[0003] However, existing impurity removal devices have the following problems: they generally use filter screens to filter and remove impurities from wastewater after the use of chemicals. However, during use, impurities easily adhere to or accumulate on the surface of the filter screens, affecting the wastewater flow rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that typically use filter screens to remove impurities from wastewater after the application of chemicals, where the filter screens are prone to the adhesion or accumulation of impurities during use, thus affecting the wastewater flow rate. Therefore, this invention proposes a wastewater treatment post-treatment impurity removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater treatment agent post-treatment impurity removal device includes two side plates and a filter screen. The two side plates are provided with grooves on their adjacent sides to facilitate filter screen installation. The filter screen is fixedly installed in the grooves of the two side plates by bolts on both sides. The side plates are provided with a scraping mechanism and a disturbance mechanism to facilitate cleaning of the filter screen. The scraping mechanism is provided with a rinsing mechanism to improve the cleaning effect of the scraping mechanism.

[0007] In one possible design, the scraping mechanism includes four top columns, a top plate, two electric telescopic rods, two scrapers, and two top frames. The bottom ends of the four top columns are fixedly connected to the top sides of the two side plates, and the top ends of the four top columns are fixedly connected to the bottom four corners of the same top plate. The fixed ends of the two electric telescopic rods are fixedly connected to the bottom of the same top plate, and the telescopic ends of the two electric telescopic rods are fixedly connected to the tops of the two top frames. The two top frames are both U-shaped, and the bottom sides of the two top frames are fixedly connected to the top sides of the two scrapers. The two scrapers are located on both sides of the same filter screen and are triangular in shape.

[0008] In one possible design, the rinsing mechanism includes two connecting frames, two pump bodies, two hoses, and water pipes. The two connecting frames are respectively fixedly mounted on the outside of the fixed ends of the two electric telescopic rods. The two pump bodies are respectively fixedly mounted on the bottom of the two connecting frames by bolts. One end of each of the two hoses is located at the water outlet of the two pump bodies. The water inlet of each of the two pump bodies is connected to an external water tank through a pipe. The other end of each of the two hoses is connected to the two water pipes. The two water pipes are respectively mounted on the inclined surfaces of the two scrapers. Each of the two water pipes is equipped with a rinsing pipe for rinsing the scraped area.

[0009] In one possible design, the disturbance mechanism includes two air pumps, two air pipes, and multiple semi-rings. The two air pumps are respectively fixed to the top of two side plates by bolts. The two ends of the two air pipes are respectively connected to the air outlets of the two air pumps. The air inlets of the two air pumps are connected to the outside through pipes and are equipped with filter plates for filtering impurities and foreign objects. The two air pipes are both U-shaped. The multiple semi-rings are respectively sleeved on the outside of the two air pipes and fixed to both sides of the side plates by bolts. The bottom of the two air pipes is provided with disturbance pipes for discharging air bubbles to disturb the surface of the filter screen.

[0010] In one possible design, the number of flushing pipes is set to multiple and they are located at the scraping points of the two scrapers respectively.

[0011] In one possible design, the number of disturbance tubes is set to multiple and located at the bottom of both sides of the filter screen.

[0012] In this application, when the filter screen needs to be scraped and cleaned, the external controller issues a command to start the electric telescopic rod. The telescopic end of the electric telescopic rod moves up and down under electric drive. Since the telescopic end of the electric telescopic rod is fixedly connected to the top of the top frame, the top frame will move up and down accordingly. Since the bottom two sides of the top frame are fixedly connected to the top two sides of the scraper, the scraper will scrape up and down on the surface of the filter screen. The scraper is set in a triangular shape. This special shape can better contact the surface of the filter screen during the scraping process and effectively remove the impurities on the filter screen.

[0013] While the scraping mechanism cleans the filter screen, the external controller starts the pump. The pump's inlet is connected to an external water tank via a pipe. Under the pump's suction, water is drawn from the tank and transported to the water pipe through a hose. Since the water pipe has multiple flushing pipes located at the scraping points of the two scrapers, water is sprayed from the flushing pipes to powerfully flush the scraping points, further removing impurities from the filter screen and improving the cleaning effect.

[0014] During the operation of the filter, an external controller starts the air pump. The air pump's inlet is connected to the outside through a pipe, and a filter plate is installed on the pipe to filter the intake air and prevent impurities from entering the air pump. The filtered air is delivered to the air pipe, which has multiple agitator tubes at the bottom. These agitator tubes are located on both sides of the bottom of the filter. Air is discharged through the agitator tubes to form bubbles. As the bubbles rise on the filter surface, they create disturbances. This disturbance reduces the accumulation of impurities on the filter surface, making the impurities in the wastewater more evenly distributed in the water, facilitating subsequent treatment and improving the efficiency of wastewater impurity removal.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, the scraping mechanism drives the scraper to scrape up and down on the filter screen surface through an electric telescopic rod, which can remove impurities on the filter screen in a timely manner and prevent impurities from accumulating too much on the filter screen surface and affecting the filtration effect. The rinsing mechanism rinses the scraped area at the same time as scraping, further washing away impurities. The two work together to greatly improve the impurity removal efficiency of the filter screen.

[0017] The agitation mechanism creates disturbance on the filter screen surface by expelling air bubbles, which makes the impurities in the wastewater more evenly distributed in the water, avoiding excessive accumulation of impurities in local areas of the filter screen, reducing the burden on the filter screen, and extending the service life of the filter screen.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1-4 A waste removal device includes two side plates 1, a filter screen 2, a scraping mechanism, a rinsing mechanism, and a disturbance mechanism. The two side plates 1 are arranged opposite each other, and grooves are provided on their adjacent sides. The filter screen 2 is fixedly installed in the grooves of the two side plates 1 by bolts on both sides, thereby realizing the installation of the filter screen 2. The scraping mechanism, rinsing mechanism, and disturbance mechanism are integrated on the side plates 1 to achieve efficient cleaning of the filter screen 2 and wastewater waste removal.

[0026] The scraping mechanism includes four top columns 3, a top plate 4, two electric telescopic rods 6, two scrapers 5, and two top frames 7. The bottom ends of the four top columns 3 are fixedly connected to the top sides of the two side plates 1 by welding or bolting. The top ends of the four top columns 3 are fixedly connected to the bottom four corners of the same top plate 4 by welding or bolting, thus forming the support frame of the entire scraping mechanism. The fixed ends of the two electric telescopic rods 6 are fixedly set at the bottom of the same top plate 4 by bolts to ensure that the electric telescopic rods 6 are installed firmly. The telescopic ends of the two electric telescopic rods 6 are respectively connected to the two top frames 7. The top is fixedly connected by welding or bolts. The two top frames 7 are both U-shaped. Their bottom sides are fixedly connected to the top sides of the two scrapers 5 by welding or bolts. The two scrapers 5 are located on both sides of the same filter screen 2, and the scrapers 5 are triangular. This shape is conducive to better scraping off the impurities on the filter screen 2 during the scraping process. When it is necessary to scrape and clean the filter screen 2, the electric telescopic rod 6 is activated. The telescopic end of the electric telescopic rod 6 drives the top frame 7 to move up and down, which in turn drives the scraper 5 to scrape up and down on the surface of the filter screen 2 to remove the impurities on the filter screen 2.

[0027] The flushing mechanism includes two connecting frames 8, two pump bodies 9, two hoses 10, and a water pipe 11. The two connecting frames 8 are fixed to the outside of the fixed ends of the two electric telescopic rods 6 by welding or bolting. The two pump bodies 9 are fixed to the bottom of the two connecting frames 8 by bolts to ensure that the pump bodies 9 are firmly installed. One end of each of the two hoses 10 is connected to the outlet end of the two pump bodies 9 by threaded connection or snap-fit ​​connection. The inlet ends of both pump bodies 9 are connected to an external water tank through pipes to draw water from the tank. The other ends of the two hoses 10 are connected to two water pipes 11 respectively. The two water pipes 11 are set on the inclined surfaces of the two scrapers 5 by means of clamps or welding. Both water pipes 11 are equipped with flushing pipes 12 for rinsing the scraped areas. While the scraping mechanism is scraping and cleaning the filter screen 2, the pump body 9 is started. The pump body 9 draws water from the external water tank and delivers the water to the water pipes 11 through the hoses 10. The hoses 10 are relatively long and are then sprayed out through the flushing pipes 12 to rinse the scraped areas of the scraper 5, further improving the cleaning effect.

[0028] The disturbance mechanism includes two air pumps 13, two air pipes 14, and multiple semi-rings 16. The two air pumps 13 are respectively bolted to the top of the two side plates 1 to ensure stable installation. The two ends of the two air pipes 14 are connected to the outlets of the two air pumps 13 via threaded connections or snap-fit ​​connections. The inlet ends of both air pumps 13 are connected to the outside via pipes, and the pipes are equipped with filter plates for filtering impurities and foreign objects to prevent impurities from entering the air pumps 13. Both air pipes 14 are U-shaped. Each half-ring 16 is respectively fitted onto the outside of the two air pipes 14 and fixed on both sides of the side plate 1 with bolts to fix the position of the air pipes 14. The bottom of each air pipe 14 is provided with a disturbance pipe 15 for discharging bubbles to disturb the surface of the filter screen 2. During operation, the air pump 13 is started, and the air pump 13 draws in air from the outside. After being filtered by the filter plate, the air is delivered to the air pipes 14 and then discharged through the disturbance pipes 15. The bubbles disturb the surface of the filter screen 2 as they rise, reducing the accumulation of impurities on the surface of the filter screen 2 and improving the efficiency of wastewater removal.

[0029] This application can be used in the field of wastewater treatment, or in other fields applicable to this application.

Multiple agitation pipes 15 are set and located at the bottom of both sides of the filter screen 2 respectively. By setting multiple flushing pipes 12 and agitation pipes 15, the accumulation of impurities in a certain place can be reduced through the cleaning effect of the filter screen 2.

[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the electric telescopic rod 6, pump body 9 and air pump 13 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
