Abstract

The utility model relates to a pipeline liquid filter that is used for industries of petroleum, chemical engineering, metallurgy, sewage treatment, etc., in particular to a barrel-shaped spraying type filter, comprising a housing body, a filtering core arranged in the housing body, a filtering screen arranged in the filtering core, an inlet flange communicated with the feed inlet of the filtering core, an outlet flange communicated with the outlet of the main housing body, and flange dicks fixed on the housing body and the upper end of the filtering core. The barrel-shaped spraying type filter also comprises a spray head and a detention warehouse. The spray head is arranged at the inner cavity of the filtering core and is connected with the feed inlet of the filtering core; the detention warehouse is arranged at the bottom of the filtering core and is communicated with the inner cavity of the filtering core; the bottom of the detention warehouse is provided with a sewage draining outlet which is provided with a sewage draining screw bolt. The barrel-shaped spraying type filter of the utility model has large area of passage, good filtering effect and long service life, does not need to clean, relieves the labor intensity of workers, and improves the working efficiency; the filtering screen is uneasily blocked and damaged.

Description

The formula filter is swept in barrel-shaped spray

Technical field the utility model relates to the pipeline liquid filter that industries such as a kind of oil, chemical industry, metallurgy and sewage disposal are used, and the formula filter is swept in a kind of specifically barrel-shaped spray.

The present pipeline liquid filter of background technology great majority are to adopt filter screen structure to filter, and promptly are that a tubbiness filter core is set in main casing.Be provided with screen pack in the filter core, liquid to be filtered flows directly into the tubbiness filter core from import, is flowed out by outlet behind the net filtration after filtration, and the impurity that is filtered out is trapped in the screen pack, manually whole taking-up of screen pack is cleaned.This filter type exists area of passage insufficient, and foreign material roll in filter screen, thereby cause foreign material to be bonded in and form obstruction on the filter screen, make the pressure loss excessive, because filter screen stops up, filter interior pressure is strengthened, cause the filter screen cracky, do not reach filter effect.In liquid being filtered, exist under the situation of more impurity, almost all will have every day the special messenger to clean once, as clean untimelyly, also can cause device damage; Be labor intensive, the equipment that also influences runs well, particularly in the oil extraction course of conveying, because maintenance filter need stop transportation work and just can finish, thereby cause economic loss difficult to the appraisal.

Utility model content the purpose of this utility model is to provide a kind of barrel-shaped spray that can address the above problem to sweep the formula filter.This filter area of passage is big, good filtration effect, and it is stifled damaged that filter screen is difficult for card, long service life.

In order to realize described purpose, the utility model adopts following technical scheme: the formula filter is swept in a kind of barrel-shaped spray, comprise housing, be positioned at the ring flange that the filter core of housing, the filter screen that is positioned at filter core, the suction flange with the filter core feeding inlet, the outlet(discharge) flange that communicates with the main casing outlet, housing and filter core upper end install, it also comprises shower nozzle and is detained the storehouse; Shower nozzle is positioned at the filter core inner chamber and is connected with the filter core charging aperture; The delay storehouse is installed on the filter core bottom and communicates with the filter core inner chamber, is detained the bottom, storehouse and is provided with sewage draining exit, and sewage draining exit is equipped with the blowdown bolt.

Adopt technique scheme, be connected with shower nozzle at the filter core charging aperture, liquid sprays around everywhere through shower nozzle, and promptly liquid forms percussion flow to scattering everywhere, the filter screen area of passage is abundant, filter screen is difficult for stopping up, and the pressure and the flow of filter interior do not change, and the pressure that filter screen bears is little, cracky has not been realized good filter effect; The delay storehouse has been installed in the filter core bottom, and the impurity that is detained on the filter screen is swept by spray, adds that the effect of gravity enters the delay storehouse, opens the blowdown bolt, the impurity that is detained in the storehouse can be discharged.Thereby the release cleaning alleviates labor strength, increases work efficiency.

The utility model is described in further detail below in conjunction with accompanying drawing.

Description of drawings Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

Among the figure: 1-housing, 101-concave surface, 2-filter core, 201-filter core charging aperture, 202-filter core inner chamber, 3-filter screen, 4-suction flange, 5-outlet(discharge) flange, 6-ring flange, 7-shower nozzle, 8-delay storehouse, 9-sewage draining exit, 10-blowdown bolt, 11-through hole.

Specific embodiment embodiment 1, as shown in Figure 1: the formula filter is swept in a kind of barrel-shaped spray, the ring flange 6 that comprise housing 1, be positioned at the filter core 2 of housing 1, the filter screen 3 that is positioned at filter core 2, the suction flange 4 that communicates with filter core charging aperture 201, the outlet(discharge) flange 5 that communicates with housing 1 outlet, housing 1 and filter core 2 upper ends installs, it also comprises shower nozzle 7 and is detained storehouse 8; Shower nozzle 7 is positioned at filter core 2 inner chambers and is connected with filter core charging aperture 201; Being detained storehouse 8 communicates between housing 1 chamber inner bottom part and filter core 2 bottoms and with filter core inner chamber 202, housing 1 bottom is provided with concave surface 101, the openend that is detained storehouse 8 is fastened on concave surface 101, be detained storehouse 8 outer walls with concave surface 101 around interference fit will be detained storehouse 8 and fix, bottom and housing 1 bottom of being detained storehouse 8 are same parts, these parts are provided with sewage draining exit 9, and sewage draining exit 9 is equipped with blowdown bolt 10.。

Embodiment 2, and in the present embodiment, delay storehouse 8 is positioned at housing 1 chamber outer bottom and communicates with filter core inner chamber 202, is provided with sewage draining exit 9 in delay 8 bottoms, storehouse, and housing 1 bottom is provided with through hole 11, and filter core 2 bottoms are installed in through hole 11, with through hole 11 sealings.Other structure is identical with embodiment 1.
