Filter

Technical Field

The utility model relates to a filter technical field especially relates to a filter.

Background

The filtration is a process of separating liquid and solid particles by using a porous substance (a sieve plate, a filter membrane, or the like) to block and carry large solid particulate matter, and is generally applied to a pretreatment and an advanced treatment process of a sewage treatment process, and the pretreatment is generally a process of separating liquid and solid particles by using a large-aperture screen filtration to block large solid particulate matter using a porous substance (a sieve plate, a filter membrane, or the like). Various filters have been manufactured for filtration, mainly for separating solid particles from a liquid in a suspension; or separating two immiscible liquids with different densities in the emulsion; it can also be used to remove liquids from wet solids, such as by spin drying clothes in a washing machine; the special overspeed tubular separator can also separate gas mixtures with different densities, such as enriched and separated gaseous uranium hexafluoride; some settling centrifuges can also grade solid particles according to density or granularity by utilizing the characteristic that solid particles with different densities or granularities have different settling speeds in liquid. The filter is widely applied to chemical, petroleum, food, pharmacy, ore dressing, coal, water treatment, ships and other departments. The filter consists of a cylinder body, a stainless steel filter screen, a pollution discharge part, a transmission device and an electric control part.

However, when the filter is used for a long time, the filter element is often blocked by filter residues, which causes poor effect in the process, and even the filter element is easy to block, resulting in reduced filtering efficiency and even damage to the filter element.

Detailed Description

The following describes an implementation structure of the present invention with reference to the drawings.

Example one

As shown in fig. 1 to 4, the filter comprises an auger 11 and a filter screen 12, wherein the filter screen 12 is distributed at the outer end of the auger 11 and is matched with the auger 11, and the diameter of a filter hole in the filter screen 12 is 300nm in order to filter small impurities.

A driving mechanism 2 is added into the filter, the driving mechanism 2 comprises a motor 21 and a speed reducer 22, an output shaft of the motor 21 is connected with an input shaft of the speed reducer 22, and an output shaft of the speed reducer 22 is connected with the packing auger 11. The driving mechanism 2 is used for driving the packing auger 11 to rotate around the central axis of the packing auger. In order to prevent the packing auger 11 from rusting, the packing auger 11 is made of stainless steel materials.

Principle of operation

As shown in fig. 5, the filter is inclined and one end of the filter screen 12 is connected with the pipeline, at this time, the filter screen 12 is in a fixed state, since there are more impurities in the liquid in the pipeline, these impurities will be filtered by the filter screen 12 and retained in the filter when passing through the filter, the liquid comes out from the filtering holes in the filter screen 12 to complete the filtering, and in order to achieve automatic slag discharge, the motor 21 is started to drive the reducer 22 and further drive the auger 11 to rotate, since the auger 11 is tightly matched with the filter screen 12, under the rotation of the auger 11, the filter slag is driven by the auger 11 to rise, and further comes out from the other end of the filter screen 12, namely the outlet 14 of the filter screen 12, so as to complete the automatic slag discharge, and achieve long-term filtering while slag.

Example two

As shown in fig. 6 to 7, the main difference between this embodiment and the first embodiment is that a filter cartridge 13 is disposed outside the filter screen 12 for supporting the filter screen 12, so as to better make the filter screen 12 closely fit the packing auger 11. The filter structure is as follows:

the utility model provides a filter, includes auger 11 and filter screen 12, filter screen 12 distributes auger 11 outer end and with 11 cooperations of auger, in order to filter less debris, the diameter 1200nm of filtration pore in the filter screen 12. The filter also comprises a filter cylinder 13, wherein 9 through holes 15 (the number of the through holes 15 can be one) are arranged on the filter cylinder 13, the filter cylinder 13 is arranged at the outer end of the filter screen 12 and used for supporting the filter screen 12 so as to better enable the filter screen 12 to be tightly attached to the packing auger 11, and the filter cylinder 13 is made of stainless steel materials so as to prevent the filter cylinder 13 from rusting.

Principle of operation

As shown in fig. 7, the filter is inclined and one end of the filter cartridge 13 is connected with the pipeline, at this time, the filter cartridge 13 is in a fixed state, since there are many impurities in the liquid in the pipeline, these impurities will be filtered by the filter screen 12 and retained in the filter when passing through the filter, the liquid comes out from the filter holes in the filter screen 12 and then falls down through the through holes 15 in the filter cartridge 13 to complete the filtering, and in order to achieve the automatic slag discharge, the motor 21 is started to drive the speed reducer 22 and further drive the auger 11 to rotate, because the auger 11 is tightly matched with the filter screen 12, under the rotation of the auger 11, the filter slag is driven by the auger 11 to rise, and further comes out from the other end of the filter screen 12, namely the outlet 14 of the filter screen 12, so as to complete the automatic slag discharge, and achieve the long.

EXAMPLE III

As shown in fig. 6 to 7, the difference between the present embodiment and the second embodiment is that the diameter of the filter holes in the filter screen 12 is 800 nm.
