Abstract

The utility model discloses a filter device of a siphon decanter and aims at providing a filter device of a siphon decanter, which can effectively filter suspended matters in supernatant liquid in a biochemical tank. The filter device comprises a filter cylinder which is detachably connected with a pipe orifice of a water suction pipe of a siphon decanter as well as a filter mesh arranged in the filter cylinder. The filter device disclosed by the utility model has the advantages of reasonable structure, convenience in use and low manufacturing cost, and is very suitable for filtering the supernatant liquid in the discharge biochemical tank of the siphon decanter.

Description

The filtration unit of siphonic decant device

Technical field

The utility model relates to strains the hydrophone technical field, especially relates to a kind of filtration unit of siphonic decant device.

Background technology

The siphonic decant device is a kind of water-freeing arrangement commonly used in the sequencing batch active sludge sewage disposal.In recent years, sequencing batch active sludge is handled waste water and is more and more received publicity, that this technology compares is simple in other technology, excess sludge dispose trouble less, save investment, take up an area of less, working cost is low, operation scheme is flexible.Owing to be quiescent setting, so liquid effluent impurity is few.

Existing siphonic decant device, mainly by U-shaped pipe, the person in charge that catchments, catchment be in charge of, water absorption tube, water shoot, vent valve etc. form.During use, inject sewage in biochemistry pool, through aeration and the precipitation of certain hour, open vent valve, the supernatant liquor in the biochemistry pool is entered by the water absorption tube of siphonic decant device, and the person in charge that is in charge of, catchments through catchmenting, U-shaped pipe arrive water shoot and discharge.Because the water absorption tube of existing siphonic decant device does not arrange effective filtration unit, still has a certain amount of suspended substance in the supernatant liquor of discharge, the water quality of the supernatant liquor of being discharged by water shoot is therefore desirable not enough.

The utility model content

The utility model has overcome shortcoming of the prior art, and a kind of filtration unit that can effectively filter the siphonic decant device of suspended substance in the interior supernatant liquor of biochemistry pool is provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of filtration unit of siphonic decant device, it comprises cartridge filter that the water absorption tube mouth of pipe with the siphonic decant device removably connects, is arranged on the filtering net in the cartridge filter.

Preferably, described cartridge filter is connected with water absorption tube by bolt.

Preferably, described filter network card is connected in the cartridge filter.

Preferably, described filtering net is stainless (steel) wire or plastic wire.

Compared with prior art, the utlity model has following advantage:

Be installed in the mouth of pipe of the water absorption tube of siphonic decant device when (1) the utility model uses, the supernatant liquor that is entered by water absorption tube is effectively filtered by the utility model, suspended substance in the supernatant liquor is isolated in the biochemistry pool, therefore, through adding the supernatant liquor that siphonic decant device of the present utility model is discharged, its water quality is effectively promoted, and sewage treatment effect is better.

(2) the utility model connects by the mode that the removably connects water absorption tube with the siphonic decant device, so when the utility model was carried out maintenance of clean-up, its dismounting was comparatively convenient.

(3) the utility model is rational in infrastructure, and is easy to use.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is installed in front view on the siphonic decant device for the utility model;

Fig. 2 is the enlarged view of A part among Fig. 1;

Fig. 3 is the left view of Fig. 1.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Fig. 1 and Fig. 3 are respectively the utility model and are installed in front view and left view on the siphonic decant device, as seen from the figure, the siphonic decant device mainly comprises U-shaped pipe 11, catchment be responsible for 12, catchment be in charge of 13, water shoot 14 and vent valve 15.One side of U-shaped pipe 11 connects the water shoot 14 that is lower than lowest water level, the other side connects to catchment is responsible for 12, catchment to be responsible for and arrange on 12 how catchmenting of group symmetry is in charge of 13, catchment be in charge of 13 arrange a plurality of downwards and the mouth of pipe stretch into the water absorption tube 10 of sewage level, vent valve 15 is arranged on an end of U-shaped pipe 11 and is higher than maximum stage.By opening and closing vent valve 15, the discharge that realizes supernatant liquor in the biochemistry pool with stop.

Fig. 2 is the enlarged view of A part among Fig. 1, wherein mainly show the filtration unit of siphonic decant device, the filtration unit of this siphonic decant device is arranged on the mouth of pipe of siphonic decant device water absorption tube 10, it comprise with water absorption tube 10 mouths of pipe with bolted cartridge filter 1, be arranged on the filtering net 2 in the cartridge filter 1, filtering net 2 adopts stainless (steel) wire or plastic wire, filtering net 2 preference cards are connected in the cartridge filter 1, can also be removably connecting of alternate manner, as be threaded, with cleaning and the replacing that makes things convenient for filtering net 2.Certainly, cartridge filter 1 can also be removably connecting of alternate manner with water absorption tube 10, as clamping, be threaded.

As shown in Figure 2, the utility model is installed in the mouth of pipe of the water absorption tube 10 of siphonic decant device when using, the supernatant liquor that is entered by water absorption tube 10 is effectively filtered by this utility model, suspended substance in the supernatant liquor is isolated in the biochemistry pool, therefore, through adding the supernatant liquor that siphonic decant device of the present utility model is discharged, its water quality is effectively promoted, and sewage treatment effect is better.Meanwhile, the utility model connects by the mode that the removably connects water absorption tube 10 with the siphonic decant device, so when the utility model was carried out maintenance of clean-up, its dismounting was comparatively convenient.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
