DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application embodiment discloses a drainage collection device for a membrane filter press. Figure 1-5A drainage collection device for a diaphragm filter press comprises a frame 1 and a body 2 mounted on the outer wall of the top of the frame 1. The opposite outer walls of the frame 1 are fixedly connected with guide rails 3. The inner walls of the two guide rails 3 are slidably connected with a plurality of sliders 4. The opposite outer walls of every two adjacent sliders 4 are commonly fixedly connected with a water collecting box 5. The water collecting box 5 is located directly below the body 2. The bottom of the water collecting box 5 is inclined. A sewage pipe 7 is arranged on the outer wall of the bottom of one end of the water collecting box 5 that is inclined downward. The sewage pipe 7 is connected to the inner cavity of the water collecting box 5. The water collecting box 5 is located directly below the body 2. The bottom of the water collecting box 5 is inclined. The sewage pipe 7 is connected to the inner cavity of the water collecting box 5. The water collecting box 5 is located directly below the body 2. A filter screen 6 is provided on the inner wall at the bottom just above the sewage pipe 7, a scraper 8 is installed in the inner cavity of the water collecting box 5, and a cleaning mechanism for driving the scraper 8 to move and scrape is installed on the outer wall of the water collecting box 5. A slag discharge port 13 is provided on the bottom outer wall of one end of the water collecting box 5 that is inclined upward, and a slag discharge box 14 is fixedly connected to the bottom outer wall of the water collecting box 5 located at the slag discharge port 13. The slag discharge box 14 is connected to the inner cavity of the water collecting box 5 through the slag discharge port 13, and a rotating shaft 15 is rotatably connected to the inner wall of the slag discharge box 14, and a threaded conveying blade 16 is fixedly connected to the outer wall of the rotating shaft 15.

[0023] The cleaning mechanism includes two threaded rods 9 rotatably connected to the outer wall of the top of the water collecting box 5 , the outer walls of the two threaded rods 9 are threadedly connected with threaded blocks 18 , and the outer walls opposite to the two threaded blocks 18 are fixedly connected with connecting plates 19 .

[0024] Two telescopic rods 20 are fixedly connected to the bottom outer wall of the connecting plate 19 , the bottom ends of the two telescopic rods 20 are fixedly connected to the top outer wall of the scraper 8 , and springs 21 are installed on the outer walls of the two telescopic rods 20 .

[0025] The cleaning mechanism also includes a dual-axis motor 11 fixedly mounted on the outer wall of one end of the water collecting box 5, and the output shafts at both ends of the dual-axis motor 11 are fixedly connected to the second bevel gear 12, and the two threaded rods 9 are fixedly connected to the first bevel gear 10 at one end close to the dual-axis motor 11, and the two first bevel gears 10 are meshed with the two second bevel gears 12.

[0026] A driving motor 17 is fixedly mounted on the outer wall of the slag discharge box 14 at one end away from the opening. The output shaft end of the driving motor 17 penetrates the slag discharge box 14 and is fixedly connected to one end of the rotating shaft 15 .

[0027] The implementation principle of the drainage collection device of the membrane filter press according to the embodiment of the present application is as follows: when in use, the water collecting box 5 is pushed so that the multiple sliders 4 on the outer wall thereof slide on the inner walls of the two guide rails 3 until the water collecting box 5 slides to the bottom of the machine body 2, and then the machine body 2 is started to start the dehydration operation. At this time, the sewage flows downward through the machine body 2 to the inner cavity of the water collecting box 5, and due to the inclined setting of the bottom of the water collecting box 5, the sewage is concentrated to flow to the sewage pipe 7, and is uniformly discharged into the sewage channel through the sewage pipe 7. Before being discharged, the sewage will be filtered through the filter screen 6 to filter out larger impurities inside, so as to prevent the impurities from flowing into the sewage pipe 7 and causing blockage;

[0028] When the water collecting box 5 is used for a long time, impurities and sludge are attached to the inner wall of the bottom and the surface of the filter screen 6. The double-axis motor 11 is started through the cleaning mechanism. The output shafts at both ends of the double-axis motor 11 drive the second bevel gear 12 to rotate. The two second bevel gears 12 synchronously drive the two first bevel gears 10 meshing therewith to rotate in the same direction. Then, the two threaded rods 9 are driven to rotate synchronously through the first bevel gears 10, so that the threaded rods 9 are threadedly rotated on the inner surfaces of the two threaded blocks 18. The threaded blocks 18 rotate on the outer wall of the threaded rods 9 toward the double-axis motor 1 1, the two threaded blocks 18 drive the scraper 8 to move through the connecting plate 19 and the telescopic rod 20, and the scraper 8 scrapes the impurities and sludge on the bottom of the water collecting box 5 and the surface of the filter screen 6 until the scraper 8 scrapes the sludge to the slag discharge port 13, so that the sludge falls into the slag discharge box 14, and then the driving motor 17 drives the rotating shaft 15 and the threaded conveying blades 16 to rotate to discharge the sludge impurities. Compared with the prior art, the impurities deposited in the water collecting box 5 can be cleaned in time to avoid the impurities from being deposited and emitting odors for a long time;

[0029] It is worth noting that when the scraper 8 moves toward the dual-axis motor 11, it will slowly move upward with the tilted setting of the bottom of the water collecting box 5, and then the scraper 8 will squeeze the two telescopic rods 20 upward. The two telescopic rods 20 will contract and squeeze the spring 21, causing the spring 21 to deform and generate elastic force to act in the opposite direction on the scraper 8, so that the bottom end of the scraper 8 is always against the bottom of the water collecting box 5, ensuring that the water collecting box 5 can always scrape away impurities and sludge when moving.
