Abstract

The utility model discloses a conic back-roll sieve tube. The conic back-roll sieve tube comprises a round end cover, a fixed ring, a reinforcing rib and filter strips, wherein the central axis of the round end cover and the central axis of the fixed ring are arranged on a same straight line, the diameter of the round end cover is less than the diameter of the fixed ring, the reinforcing rib is arranged between the round end cover and the fixed ring, one end of the reinforcing rib is fixed on the inner side of the fixed ring, the other end of the reinforcing rib is fixed on the round end cover, the filter strips are helicoidally wound on the outer side of the reinforcing rib, adjacent filter strips have a fixed clearance, the contact points between the filter strips and the reinforcing rib are fixedly connected with one another, and a thread hole is formed in the center of the round end cover. The conic back-roll sieve tube has large compressive strength and long service life; due to the conic design, the conic back-roll sieve tube well guarantees filtrate to pass through smoothly in filtering; due to the adoption of the filter strips with trapezoidal cross sections, the conic back-roll sieve tube is convenient and fast to filter.

Description

A kind of taper back-roll screen casing

Technical field

The utility model relates to separated and filter field, is specifically related to a kind of taper back-roll screen casing.

Background technology

Filter sieve tube is generally used in the separated of the fields such as iron and steel, papermaking and pharmacy and filters.Main filter sieve tube mainly adopts certain thickness materials in the tube in the market, and in the surface punching of materials in the tube, then adopts the filtration silk screen of different meshes to be coated and reaches filter effect.But during actual use, owing to filtering, silk screen intensity is limited, thereby its service life is short, at larger pressure filtration, easily damages, and its compressive property is poor, and sediment is easily piled up, and is not easy cleaning.

Utility model content

For solving the problems of the technologies described above, it is large that we have proposed a kind of compression strength, and long service life is easy to the taper back-roll screen casing of washing and precipitating thing.

For achieving the above object, the technical solution of the utility model is as follows:

A taper back-roll screen casing, is comprised of circular end cap, retainer ring, reinforcement and filtering strap; The central axis setting of the central axis of described circular end cap and described retainer ring point-blank, the diameter of described circular end cap is less than the diameter of described retainer ring, described reinforcement is located between described circular end cap and retainer ring, described retainer ring inner side is fixed in its one end, and the other end is fixed on described round nose and covers; Described filtering strap spiral winding is located at described reinforcement outside, between adjacent filtering strap, is provided with fixed interval (FI); The contact point of described filtering strap and reinforcement is mutually permanently connected; Described circular end cap center is provided with a screwed hole.

Preferably, the cross section of described filtering strap is trapezoidal.

Preferably, described reinforcement and filtering strap material are stainless steel.

Preferably, the contact point of described reinforcement and filtering strap fixes by welding.

Preferably, the quantity of described reinforcement is 18.

Due to the utilization of technique scheme, the utility model compared with prior art has the following advantages and effect:

Back-roll taper screen casing of the present utility model, by boxing filtering strap on reinforcement, its solder joint is reliably firm, reasonable integral structure, compression strength is large, long service life; The design of its taper, when filtering, has better guaranteed the smoothness of passing through of filter liquide; Cross section is the employing of trapezoidal filtering strap, and the filtration of the taper screen casing that makes to rewind is convenient and swift.

Accompanying drawing explanation

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

The specific embodiment

Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.

Embodiment

As shown in Figure 1, Figure 2 and Figure 3, a kind of taper back-roll screen casing, is trapezoidal filtering strap 4 by circular end cap 1,2,18 reinforcements 3 of retainer ring and cross section and forms; The central axis setting of the central axis of described circular end cap 1 and described retainer ring 2 point-blank, the diameter of described circular end cap 1 is less than the diameter of described retainer ring 2, described reinforcement 3 is located between described circular end cap 1 and retainer ring 2, described retainer ring 2 inner sides are fixed in its one end, and the other end is fixed on described circular end cap 1; Described filtering strap 4 spiral windings are located at described reinforcement 3 outsides, between adjacent filtering strap 4, are provided with fixed interval (FI) 5; Described filtering strap 4 fixes by welding with the contact point 6 of reinforcement 3; Described circular end cap 1 center is provided with a screwed hole 7; Described reinforcement and filtering strap material are stainless steel.

Back-roll taper screen casing of the present utility model, by boxing filtering strap 4 on reinforcement 3, its solder joint is reliably firm, and each solder joint can bear the pulling force of 2000-3000N, reasonable integral structure, compression strength is large, long service life; The design of its taper, when filtering, has better guaranteed the smoothness of passing through of filter liquide; Cross section is the employing of trapezoidal filtering strap, the filtering along being trapezoidal fixed interval (FI) 5 of filtered water stream 8, and the filtration of the taper screen casing that makes to rewind is convenient and swift.

Above-described is only the preferred embodiment of a kind of taper back-roll of the utility model screen casing; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
