Description

Sewage filtering device

Technical Field

The utility model relates to a sewage filtering device, which belongs to the technical field of water treatment.

Background

Sewage treatment filters are widely used in various fields such as water supply and drainage systems in the metallurgical industry, blast furnace water systems, steam turbine cooling water systems in the power plant industry, boiler wet cooling water systems, large air compressors, large oxygen generators, large air conditioner cooling water systems, agricultural drip irrigation water systems, urban heating systems, and the like. The existing partial sewage filter is provided with a magnet for adsorbing iron impurities in sewage, for example, a sewage treatment iron impurity pretreatment device disclosed in chinese patent document CN211004958U, the device can form a magnetic field parallel to the right baffle on the right side of the water inlet pipe by arranging the electromagnet, so that the iron impurities move towards the inner wall of the right baffle under the action of magnetic force, and then the iron impurities are separated from the sewage by a collecting frame; further, as shown in chinese patent document CN111392953A, a filtering device for a cooling water pipeline is disclosed, which comprises a filter screen assembly and a magnetic assembly, wherein the magnetic assembly is formed by assembling a circular magnet ring and a ring.

SUMMERY OF THE UTILITY MODEL

Therefore, an object of the utility model is to provide a novel sewage filter device can adsorb the filtration through magnet to iron impurity, reaches better filter effect.

In order to achieve the purpose, the utility model discloses a sewage filtering device, including the vertical casing that sets up, the inside of casing includes the first filter chamber that is located the upper portion and is located the second filter chamber of lower part, be provided with the division board between first filter chamber and the second filter chamber, seted up the water gap on the division board and be used for communicateing first filter chamber and second filter chamber; a water inlet pipe and a water outlet pipe are arranged on the shell, the water inlet pipe is communicated with the first filter cavity, and the water outlet pipe is communicated with the second filter cavity; a plurality of magnetic columns are arranged in the first filtering cavity, and a filtering bag is arranged in the second filtering cavity.

At least one magnetic column is arranged on the lower end face of the partition plate.

And a compression spring is arranged above the magnetic column in the first filtering cavity.

A support part is provided at an inner side of the case, and the partition plate is detachably mounted on the support part.

The edge of the filter bag is fixedly arranged on the partition plate.

The shell comprises a cylindrical body and an upper cover, and a handle is arranged on the upper cover.

Adopt above-mentioned technical scheme, the utility model discloses a sewage filtering device, sewage gets into first filtration intracavity through the inlet tube in the use, can adsorb the iron impurity in the sewage through the magnetic column in first filtration intracavity and filter, and the mouth of a river that crosses on the division board is passed through again to the water after the filtration gets into the second filtration chamber, carries out the secondary filter through the filter bag in the second filtration intracavity and passes through the outlet pipe again and flow. The utility model discloses a sewage filtering device, assembly structure is simple, and the magnetism post is changed conveniently, and the filter effect is good.

Drawings

Fig. 1 is a schematic structural view of the sewage filtering apparatus of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in the drawing, the utility model discloses a sewage filtering device, casing 1 including vertical setting 1 the casing 1 inboard is provided with and is used for supporting part 2, division board 3 through flange detachable liftoff install in on supporting part 2, separate the inside of casing 1 through division board 3 and become the first filter chamber 4 that is located upper portion and the second filter chamber 5 that is located the lower part seted up mouth of a river 31 on division board 3 and be used for the intercommunication first filter chamber 4 and second filter chamber 5.

The water inlet pipe 6 and the water outlet pipe 7 are arranged on the shell 1, the water inlet pipe 6 is communicated with the first filtering cavity 4, and the water outlet pipe 7 is communicated with the second filtering cavity 5.

A plurality of magnetic columns 8 are arranged in the first filtering cavity 4, and a compression spring 9 is arranged at the upper end of each magnetic column 8 and used for compressing the magnetic columns 8. The housing 1 includes a cylindrical body and an upper cover 10, and the upper cover 10 is provided with a handle 11 and a locking device.

A filter bag 12 is arranged in the second filter cavity 5, and the edge of the filter bag 12 is fixedly arranged on the partition plate 3. At least one magnetic column 8 is arranged on the lower end face of the partition plate 3.

Adopt above-mentioned technical scheme, the utility model discloses a sewage filter equipment, in using sewage through inlet tube 6 entering first filter chamber 4, can adsorb the filtration to the iron impurity in the sewage through the magnetic column 8 in first filter chamber 4, the water after the filtration gets into second filter chamber 5 through the mouth of a river of crossing on division board 3 again, carries out the secondary filtration through filter bag 12 in the second filter chamber 5 and then flows through outlet pipe 7 again. The utility model discloses a sewage filtering device, assembly structure is simple, and the magnetism post 8 is changed conveniently, and the filter effect is good. When the magnetic column 8 or the filter bag 12 needs to be replaced, the upper cover 10 is opened, and then the magnetic column 8, the partition plate 3 and the filter bag 12 are taken out and replaced, which is very convenient.
