Technical Field

The invention relates to a filtering device, in particular to a filtering device for urban sewage treatment, and belongs to the technical field of environment-friendly equipment.

Background

With the rapid development of society, the living standard of people is higher and higher, cities are built larger and larger, the amount of sewage generated in the cities is more and more, and great pressure is brought to the environment protection and treatment work. The existing filters used in the sewage treatment industry are various, such as rake type and grid type filters, but generally only can filter coarse impurities, the filtering effect on fine and thready dirt such as hair is poor, the hair can enter the next treatment process, and troubles are brought to the next sewage treatment operation, so that the problem to be solved at present is solved.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the utility model provides a filter equipment for municipal sewage treatment, be equipped with the multilayer filter screen in the device, the filter screen is formed by the grid strip welding that has the fin, and the interval of grid strip is not uniform, and direction dislocation is arranged, and sewage is when passing through the filter, and hair etc. this kind of slender silk form filth can be blocked by the grid strip that takes the fin, reaches filterable purpose, the effectual problem of solving above-mentioned existence.

The technical scheme of the invention is as follows: the utility model provides a filter equipment for municipal sewage treatment, it includes barrel, upper cover and base, barrel fixed connection is in the upper portion of base, and the upper cover passes through flange and bolted connection to the top of barrel, the bottom fixedly connected with low head of barrel, at the bottom fixedly connected with outlet pipe of low head, at the top outside limit fixedly connected with import pipe of barrel, fixedly connected with support ring on the bottom inside wall of barrel, there is the through-hole in the centre of support ring, is provided with a plurality of layers and overlaps and place and detachable filter screen on the support ring.

And the upper end enclosure is connected with a pressure gauge.

The support ring is characterized in that 3-5 positioning seats are uniformly and fixedly connected above the support ring and are located on the outer side wall edge of the filter screen.

The filter screen includes shell ring and grid net, fixedly connected with one deck horizontally grid net on the inside wall of shell ring, fixedly connected with 3 ~ 5 evenly distributed's cassette on the top lateral wall of shell ring.

The grid net is fixedly connected with a plurality of grid bars which are perpendicular to each other, and the distance between the grid bars is 15-40 mm.

The grid bars are finned tubes or finned bars, and fins are arranged on the outer surfaces of the grid bars.

The filter screen is 2 ~ 5 layers, and the grid strip dislocation arrangement on the upper and lower layer filter screen.

The invention has the beneficial effects that: through above technical scheme, sewage is at first through the import pipe entering this device in, the sewage that does not have debris passes the filter screen, then gets into process on next step by the outlet pipe, and hair this kind of long and thin filiform filth such as hair then can be intercepted by the fin on the grid strip of filter screen because very tiny, gathers on the upper portion of barrel, and after hair this kind of long and thin filiform filth such as reaches a certain amount, the filter capacity can descend, barrel upper portion pressure can rise, through the data of observing the manometer, confirms whether to open the head and clear up. According to the amount of hair contained in different sewage, different filter screen layers and different grating strip intervals can be set, the requirements of various sewage treatment processes can be met, the filtration rate of the slender silk-shaped dirt such as hair can reach more than 90%, the hair can be basically removed, the adverse effect of the slender silk-shaped dirt such as hair on the next sludge fermentation evaporation treatment process is avoided, and a good application effect is achieved.
