Driven by the policies of the state and local governments at all levels on environmental protection and domestic sewage, there is a strong demand for urban and rural domestic sewage treatment. The domestic sewage industry has ushered in a spring of development, and a large number of advanced sewage treatment processes and technologies have emerged. The MBBR process principle is to add a certain amount of suspended carriers to the reactor, rely on the aeration and water flow in the aeration tank to fluidize the carriers, and then form suspended activated sludge and attached biofilm to increase the biomass and biological species in the reactor, thereby improving the treatment efficiency of the reactor. Since the liquid after sewage treatment contains fillers, direct discharge will cause waste, so a filter device is needed for filtration.

[0003] A filler sieve device for MBBR sewage treatment equipment in the prior art is relatively small in size, which makes it easy for the filler to become clogged in the device body and difficult to collect and process the filler under the sieve. At the same time, the device body in the above device is in a stationary state, resulting in low filler filtration efficiency. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-4As shown, the utility model provides a filler filter device for MBBR sewage treatment equipment, including a tank body 1, a chute 2 is provided on the surface of one side of the tank body 1, a fixed rod 4 is provided inside one side of the tank body 1, a spring 5 is provided outside the fixed rod 4, a scraping mechanism 3 is provided inside the chute 2, a filter mechanism 6 is provided on one side of the fixed rod 4, and a transmission mechanism 13 is provided on the other side of the tank body 1. The filter mechanism 6 includes a fixed shell 10 provided in the tank body 1, a filter plate 11 is fixedly installed inside the fixed shell 10, a diverter strip 12 is fixedly installed in the middle of the fixed shell 10, a collection tank 9 is provided in the fixed shell 10, and a filter hole 8 is opened on the surface of the collection tank 9.

[0023] The effect achieved by the entire embodiment 1 is that the liquid mixed with the filler is sent to the fixed shell 10 of the filter screen mechanism 6, and the liquid is caused to flow to the filter plates 11 on both sides under the action of the diverter strips 12, and the filler is filtered by the filter plates 11. With the action of the transmission mechanism 13, the filter plates 11 can be prevented from being blocked, thereby improving the filter screening efficiency. Through the setting of the transmission mechanism 13, the filter screen mechanism 6 is caused to reciprocate in the horizontal direction, thereby improving the filter screening efficiency.

[0024] Example 2, as Figure 1-4 As shown, the scraping mechanism 3 includes a first motor 17 installed in the pool body 1, one side of the first motor 17 is transmission-connected with a first screw 18, the first screw 18 is threadedly connected to a movable frame 19, the internal thread of the movable frame 19 is connected to an adjusting screw 16, and the lower part of the adjusting screw 16 is movably connected to a scraper 15, and the transmission mechanism 13 includes a mounting base 21 fixed on the outer wall of the pool body 1, a second motor 20 is fixedly installed below the mounting base 21, the output end of the second motor 20 passes through the top of the mounting base 21 and is transmission-connected to a turntable 22, a fixing pin 25 is fixedly installed on the surface of the turntable 22, and a fixing pin 25 is fixedly installed on the surface of the turntable 22. A linkage rod 23 is provided, and a connecting piece 24 is movably connected to one side of the linkage rod 23. Slide rails are fixedly installed on both sides of the upper surface of the pool body 1. Slide seats are fixedly installed on both sides of the filter screen mechanism 6. The filter screen mechanism 6 is movably connected to the inside of the pool body 1. The spring 5 is fixedly connected between the filter screen mechanism 6 and the pool body 1. The filter plate 11 is fixedly installed on one side of the diverter strip 12. Two groups of collecting troughs 9 are provided. The collecting troughs 9 are movably installed with the fixed shell 10. The first motor 17 and the first screw 18 are both installed inside the slide 2. The linkage rod 23 is movably connected between the connecting piece 24 and the fixing pin 25. The connecting piece 24 is fixedly installed with the filter screen mechanism 6.

[0025] The effect achieved by the entire embodiment 2 is that the first motor 17 can drive the first screw 18 to rotate, thereby realizing the movement of the movable frame 19. Since the adjusting screw 16 is threadedly connected to the movable frame 19 and is movably connected to the scraper 15, the vertical height of the scraper 15 can be adjusted, thereby scraping the filler above the filter mechanism 6. The first motor 17 and the first screw 18 can be installed and fixed under the action of the slide 2. At the same time, the threaded connection between the movable frame 19 and the first screw 18 enables the movable frame 19 to drive the scraper 15 to move horizontally, thereby realizing the scraping of the filler. The second motor 20 can be installed and fixed by the mounting seat 21, and the fixing pin 25 installed on the surface of the turntable 22 can rotate in a circle under the action of the turntable 22. The second motor 20 can drive the turntable 22 to rotate, and the linkage rod 23 can drive the connecting member 24 to move in a circular horizontal direction under the action of the fixed pin 25. Due to the installation of the connecting member 24 and the filter mechanism 6, the filter mechanism 6 can move synchronously, and the liquid can be sent to the filter plates 11 on both sides for filtration under the action of the diverter strip 12. The transmission mechanism 13 cooperates to achieve efficient filtration. At the same time, the collecting trough 9 can collect the filler under the filter screen in cooperation with the transmission mechanism 13. The movement of the filter mechanism 6 is smoother through the spring 5 between the filter mechanism 6 and the pool body 1. At the same time, the smoothness of the filter mechanism 6 is further improved through the cooperation of the slide seat and the slide rail.

[0026] Working principle: When the device is used, the operator starts the second motor 20 to drive the turntable 22 to rotate, thereby causing the fixed pin 25 to rotate in a circular motion, and the fixed pin 25 drives the connecting member 24 to perform a cyclic reciprocating horizontal motion under the action of the linkage rod 23. Due to the installation of the connecting member 24 and the filter mechanism 6, the filter mechanism 6 performs a horizontal reciprocating rocking, and the liquid mixed with the filler is sent to the fixed housing 10 of the filter mechanism 6. The liquid flows to the filter plates 11 on both sides under the action of the diverter strip 12, and the filler is filtered by the filter plates 11. With the action of the transmission mechanism 13, the filter plate 11 can be prevented from being blocked, thereby improving the screening efficiency. After the filtration is completed, the first motor 17 is started to rotate the first screw 18, so that the movable frame 19 drives the scraper 15 to move to the set position, and the adjusting screw 16 is rotated to move the scraper 15 to the surface of the filter plate 11. Under the action of the first screw 18, the scraper 15 pushes the filler on the surface of the filter plate 11 to the inside of the collecting tank 9. After the collection of the filler is completed, it can be drawn out from the inside of the fixed shell 10 through the handle of the collecting tank 9.
