Abstract

The utility model relates to an automatic cleaning and filtering device. The utility model has the advantages that: the inlet water enters the filter cavity from the water inlet, and the liquid which can pass through the filter membrane is discharged from the water outlet. While impurities and unfiltered liquid remain above the filter membrane. As impurities in the liquid above the filter membrane increase, its external pressure also increases. The lower cavity of the automatic cleaning valve is communicated with the upper part of the filtering membrane, and the liquid containing impurities also flows into the lower cavity. The opening of the lower cavity and the upper cavity is sealed by a sealing head, and the sealing head is supported by the pressure of a spring. When the impurity of filtration membrane top increases, to the pressure increase of sealed head, make the spring compression, sealed head breaks away from the opening, makes the liquid that contains impurity get into the epicoele, discharges from clean mouthful. When the impurity above the filter chamber reduces, pressure drops, and the spring can promote sealed head and close the opening.

Description

Automatic cleaning and filtering device

Technical Field

The utility model relates to a filter, especially, relate to an automatic cleaning filter equipment.

Background

It is a common requirement to filter impurities from liquids. The current common filtration methods are all that are to leave impurities on the filtration materials, such as filter paper, activated carbon and other filtration materials. This type of filtration requires frequent replacement or cleaning of the filter material, which can be inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide an automatic cleaning filter equipment, can automatic cleaning filter equipment, avoid changing filtering material.

The utility model discloses a realize through following technical scheme:

the utility model provides an automatic clean filter equipment, includes water inlet, outlet, clean mouthful and self-cleaning valve, water inlet intercommunication filter chamber, filter chamber intercommunication outlet, be equipped with filtration membrane between filter chamber and the outlet, self-cleaning valve includes cavity of resorption, epicoele and case, be equipped with the opening between cavity of resorption and the epicoele, the case is including sealed head, valve rod and adjustment mechanism, cavity of resorption intercommunication filter chamber, the clean mouth of epicoele intercommunication, sealed head seals the opening, sealed head passes through valve rod and connects adjustment mechanism, the inside through-hole that is equipped with of self-cleaning valve, the valve rod passes the through-hole, adjustment mechanism includes fixed plate, clamp plate and spring, valve rod fixed connection clamp plate, fixed plate fixed mounting is on self-cleaning valve's valve body, be equipped with the spring between fixed plate and the clamp plate.

According to the above technical scheme, preferably, the water inlet is provided with a coarse filter element.

The utility model has the advantages that: the inlet water enters the filter cavity from the water inlet, and the liquid which can pass through the filter membrane is discharged from the water outlet. While impurities and unfiltered liquid remain above the filter membrane. As impurities in the liquid above the filter membrane increase, its external pressure also increases. The lower cavity of the automatic cleaning valve is communicated with the upper part of the filtering membrane, and the liquid containing impurities also flows into the lower cavity. The opening of the lower cavity and the upper cavity is sealed by a sealing head, and the sealing head is supported by the pressure of a spring. When the impurity of filtration membrane top increases, to the pressure increase of sealed head, make the spring compression, sealed head breaks away from the opening, makes the liquid that contains impurity get into the epicoele, discharges from clean mouthful. When the impurity above the filter chamber reduces, pressure drops, and the spring can promote sealed head and close the opening.

Drawings

Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.

In the figure: 1. the water purifier comprises a water inlet, 2 water outlets, 3 cleaning ports, 4 filtering chambers, 5 filtering membranes, 6 lower chambers, 7 upper chambers, 8 through ports, 9 sealing heads, 10 valve rods, 11 fixing plates, 12 pressing plates, 13 springs and 14 coarse filter elements.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figures, the utility model relates to an automatic cleaning and filtering device, which comprises a water inlet 1, a water outlet 2, a cleaning port 3 and an automatic cleaning valve, wherein the water inlet is communicated with a filter chamber 4, the filter chamber is communicated with the water outlet, a filtering membrane 5 is arranged between the filter chamber and the water outlet, the automatic cleaning valve comprises a lower chamber 6, an upper chamber 7 and a valve core, a through hole 8 is arranged between the lower chamber and the upper chamber, the valve core comprises a sealing head 9, a valve rod 10 and an adjusting mechanism, the lower chamber is communicated with the filter chamber, the upper chamber is communicated with the cleaning port, the sealing head seals the through hole, the sealing head is connected with the adjusting mechanism through the valve rod, a through hole is arranged inside the automatic cleaning valve, the valve rod passes through the through hole, the adjusting mechanism comprises a fixing plate 11, a pressing plate 12 and a, and a spring is arranged between the fixed plate and the pressure plate.

In this embodiment, the inlet water enters the filter chamber from the inlet port and the liquid that may pass through the filter membrane is discharged from the outlet port. While impurities and unfiltered liquid remain above the filter membrane. As impurities in the liquid above the filter membrane increase, its external pressure also increases. The lower cavity of the automatic cleaning valve is communicated with the upper part of the filtering membrane, and the liquid containing impurities also flows into the lower cavity. The opening of the lower cavity and the upper cavity is sealed by a sealing head, and the sealing head is supported by the pressure of a spring. When the impurity of filtration membrane top increases, to the pressure increase of sealed head, make the spring compression, sealed head breaks away from the opening, makes the liquid that contains impurity get into the epicoele, discharges from clean mouthful. When the impurity above the filter chamber reduces, pressure drops, and the spring can promote sealed head and close the opening.

According to the above technical solution, preferably, the water inlet is provided with a coarse filter element 14. The coarse filter element can filter out large particle impurities in the liquid.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
