Technical Field
The utility model relates to a sewage purification field especially relates to a rotary drum grid.
Background
The drum type mechanical grating is also called fine grating filter or spiral grating machine, and is one integrated apparatus comprising fine grating dirt separator, grating slag spiral lifter and grating slag spiral squeezer. The device is an ideal device for separating floating substances, settled substances and suspended substances in water and taking out the floating substances, settled substances and suspended substances in the process of treating the urban sewage treatment plant and the industrial wastewater, and is widely applied to solid-liquid separation, filter residue cleaning, transmission and squeezing dehydration in the urban domestic sewage treatment plant and the industrial wastewater treatment project.
The general drum-type mechanical grating is a drum-shaped grating basket made of grating sheets according to grating gaps, water to be treated flows in from the front of the grating basket, is filtered by the grating and flows to a pool outlet, grating slag is intercepted on the grating surface, when the difference between the water level inside and outside the grating reaches a certain value, a rotary tooth rake arranged on a central shaft rotates to clean the sewage, and when the sewage is collected to the top of the grating basket by the slag cleaning tooth rake, the slag begins to be discharged (the grating slag falling by self weight can be discharged into a grating slag groove); then the grid rotates 15 degrees, the grid slag adhered on the rake teeth is automatically scraped by a slag removing toothed plate at the top end of the grid basket and is discharged into a grid slag groove. The grid slag is lifted by a screw conveyor at the bottom of the tank or is transported in and out of a garbage truck. One obvious disadvantage of such a grating machine is that more than one surface of the grating surface is generally adhered with dirt, and the slag removal rake can only clean the dirt in the gap and one surface.
In view of the above, there is a need for a drum grid that is thoroughly cleaned.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the drum type grating comprises a grating 1, wherein the grating 1 is cylindrical, a dirt storage bin 2 is arranged at the center of the grating, an opening is formed in the top of the dirt storage bin 2, an inner scraper 3 and an outer scraper 4 are arranged above the opening, and an arc-shaped channel is formed between the inner scraper 3 and the outer scraper 4 for the grating 1 to pass through; a fixing frame 7 for fixing the inner scraper 3 and the outer scraper 4 is arranged on one side of the dirt storage bin 2; the center of the sewage storage bin 2 is provided with a spiral conveying device 8, a conveying auger is generally adopted, and the spiral conveying device 8 extends out of the sewage storage bin 2 from one end far away from the fixed frame 7 and is connected to a sewage discharge outlet; one end of the grid 1, which is positioned at the sewage discharge outlet, is fixedly connected with an outer gear ring 9, and the outer gear ring 9 is meshed with a gear 10 at the output end of the speed reducer; the center of the gear ring is provided with a bearing which is sleeved outside the spiral conveying device 8. Store up dirty storehouse 2 like this and be fixed, interior scraper blade 3 and outer scraper blade 4 are fixed on storing up dirty storehouse 2 through mount 7, and grid 1 is rotatory around the outer wall of auger under the gear 10 drive, and overall structure is stable.
As shown in fig. 3, the grid 1 includes longitudinal bars 11 that are parallel to each other and are uniformly distributed, and transverse bars 12 that are staggered from each other are respectively disposed on two sides of the longitudinal bars 11. The transverse grid bars 12 on the inner side and the outer side of the grid 1 are staggered with each other, which is beneficial to increasing the efficiency of filter residue.
As shown in fig. 3, scraping teeth 13 are arranged on the outer side of the inner scraping plate 3 and the inner side of the outer scraping plate 4, the distance between the scraping teeth 13 is adapted to the width of the grid bars of the grating 1, and a steel wire brush 14 is arranged between the scraping teeth 13.
