Abstract

The utility model discloses a pipeline filter, which is applied for decontaminating or filtering a fluid pipeline and is characterized in that the pipeline filter is composed of a filter shell, a filter net, a filter net support pipe and an impurity precipitation chamber; the main body of the filter shell is cylindrical or rectangular; a fluid inflow pipe is arranged above the side of the filter shell; a fluid outflow pipe is arranged at the bottom end of the filter; the filter net and the filter net support pipe are arranged between the fluid inflow pipe and the fluid outflow pipe; the impurity precipitation chamber is arranged below the side of the filter net; an impurity discharging pipe and a valve are arranged below the impurity precipitation chamber. The pipeline filter disclosed by the utility model can be connected onto a fluid conveying pipeline through a flange and has the advantages of being simple in structure, long in cleaning period of the filter net and convenient and rapid in decontaminating.

Description

A kind of piping filter

Technical field

The utility model relates to a kind of fluid line filter, particularly a kind of piping filter for filter pipe liquid or gas impurities.

Background technology

Fluid line, in the transporting fluid process, due to the existence of impurity in fluid, tends to cause the obstruction of pipeline or causes the follow-up equipment running undesired, causes very burden to production run or life, therefore need in transport pipeline, carry out filtering and impurity removing.At present common filter device for pipes is not owing to there is no the removal of impurities structure, and the strainer filtering cycle is short, cleaned and changed frequent, and dismantles comparatively trouble, and what impact was produced normally carries out.

The utility model content

The purpose of this utility model is in order to address the above problem, and a kind of piping filter provided, it is simple in structure, and the filter gauze cleaning cycle is long, blowdown is convenient and swift.

The utility model is by filter housing, filter screen, screen support pipe and heavy assorted chamber form, filter housing main body profile is cylindrical or cuboid, be provided with the fluid inflow pipe above the side of filter housing, be provided with the flange sealing in the upper end of filter housing, be provided with the fluid effuser in the filter housing bottom, be provided with filter screen and screen support pipe in the middle of fluid inflow pipe and fluid effuser, the filter screen profile is oval, can prolong transverse folding, all be provided with a circular hole at an end of its major axis and the two ends of minor axis, can be enclosed within on the steady pin of screen support pipe upper end, the filter screen slant setting is in the upper end of screen support pipe, steady pin by screen support pipe upper end is fixed, and cover the upper end open of screen support pipe fully, filter screen tiltedly below be provided with heavy assorted chamber, below, heavy assorted chamber is provided with impurity-discharging pipe, the part that impurity-discharging pipe exposes to filter housing arranges valve, for discharging the foreign material of the upper part of filter screen filter.

Described filter screen horizontal tilt angle is 15 ~ 60 degree, on filter screen, gather circle or rhombus filter opening, and it is fixed that the filter opening size is come according to the size of the impurity in the fluid that will filter, and on filter screen, the diameter of three circular holes equates with the external diameter of the steady pin of screen support pipe upper end.

The beneficial effects of the utility model:

The utility model can directly be connected on fluid line by flange, and for the filtration of fluid-transporting tubing fluid, it is simple in structure, the filter gauze cleaning cycle is long, blowdown is convenient and swift.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of the filter screen of the utility model.

Fig. 3 is the structural representation of the screen support pipe upper end steady pin of the utility model.

Wherein, 1-filter housing; 11-fluid inflow pipe; 12-fluid effuser; The sealing of 13-flange; 2-filter screen; 21-circular hole; 3-screen support pipe; 31-steady pin; 4-heavy assorted chamber; 41-impurity-discharging pipe; 42-valve.

The specific embodiment

Refer to shown in Fig. 1, the present embodiment is comprised of filter housing 1, filter screen 2, screen support pipe 3 and heavy assorted chamber 4, filter housing 1 main body profile is cylindrical or cuboid, be provided with fluid inflow pipe 11 above the side of filter housing 1, fluid inflow pipe 11 ends vertically downward, be provided with fluid effuser 12 in filter housing 1 bottom, be provided with filter screen 2 and screen support pipe 3 in the middle of fluid inflow pipe 11 and fluid effuser 12, manage blue sealing 13 on the top of filter housing 1, for loading and unloading the use of filter screen 2.

Filter screen 2 profiles are oval, the densely covered circle of the above or rhombus filter opening, it is fixed that the filter opening size is come according to the size of the impurity in the fluid that will filter, it is folding that filter screen 2 can prolong transverse, all be provided with a circular hole 21 at an end of its major axis and the two ends of minor axis, the diameter of circular hole 21 equates with the external diameter of the steady pin 31 of screen support pipe 3 upper ends, and can directly overlap on steady pin 31, filter screen 2 slant settings are in the upper end of screen support pipe 3, filter screen 2 horizontal tilt angles are 15 ~ 60 °, steady pin 31 by screen support pipe 3 upper ends is fixing, and cover the upper end open of screen support pipe 3 fully, filter screen 2 tiltedly below be provided with heavy assorted chamber 4, heavy assorted chamber 4 is hemispherical dome structure, outward flange is connected with filter screen 2, bottom, heavy assorted chamber is provided with impurity-discharging pipe 41, the part that impurity-discharging pipe 41 exposes to filter housing 1 arranges valve 42, for discharging the foreign material of the upper part of filter screen 2 filter.

The course of work of the present utility model:

Fluid enters filter from fluid inflow pipe 11, then after filter screen 2 filters, from fluid effuser 13, flow out, the impurity filtered out on filter screen 2 is under self gravitation and the effect of fluid impact power, enter in heavy assorted chamber 4, after certain hour, the valve 42 of opening on the 4 lower end impurity-discharging pipes 41 of heavy assorted chamber can be got rid of the impurity in heavy assorted chamber 4, can reduce like this deposition of impurity on filter screen 2, thereby avoid the frequent clean of filter screen 2, when filter screen 2 is cleaned, can open the flange sealing 13 of filter housing 1 upper end, the folding rear taking-up of filter screen 2 is cleaned and got final product.
