Description

Suspended filler interceptor

Technical Field

The utility model relates to a suspension filler interceptor belongs to sewage treatment filler intercepting device technical field.

Background

A plurality of fillers are usually suspended in the aeration tank, and in order to prevent the fillers in the aeration tank from flowing outwards, a suspended filler intercepting device is arranged in the aeration tank.

At present, most of solid filler interceptors adopted in the industry adopt a barrel-shaped sieve, suspended fillers are intercepted through a mesh structure of the interceptors, after the solid filler interceptors are used for a long time, meshes are easily blocked, the fillers are accumulated at the interceptors, especially when the interceptors are installed on a pump inlet pipeline, the accumulated fillers influence the water passing effect, if the pump still continuously absorbs water, even the side wall of the interceptor with the barrel-shaped sieve structure is absorbed to be inwards concave.

For example, chinese patent No. CN204417199U discloses a packing intercepting device for a biological fluidized bed, which has large pores, but the overall strength is relatively low due to the large pores, and the possibility that the sidewall is sucked to be concave is higher when a blockage occurs.

The utility model provides a suspended filler interceptor, includes barrel 1, and barrel 1 sets up to the wire side structure, adopts the corrosion resistant plate to make, and corrosion resistant plate thickness range adopts 2.5mm in this embodiment between 2-3 mm. The open porosity of the stainless steel plate was in the range of 35 to 45%, and in this example, the open porosity was 40%. The shape of the cross section of the mesh 4 along the aperture is conical, the smaller end of the cone faces the inside of the cylinder 1, and the larger end of the cone faces the outside of the cylinder 1.

The inside of the cylinder body 1 is provided with the recoil pipe 2, the recoil pipe 2 comprises a pipe body 21 which is coaxial with the cylinder body 1, and the pipe body 21 is provided with a plurality of air holes 22. The flange joint between body 21 one end and the external aeration pipe, the other end stretches into in barrel 1, for enclosed construction, and confined one end sets up to the arc surface, and gas gets into recoil pipe 2, when arriving recoil pipe 2 end, acts on the arc surface, flows along the arc surface, passes through gas pocket 22 on the recoil pipe 2 again, discharges in the gas pocket 22, is difficult for forming gaseous turbulent flow more.

The air holes 22 on the tube 21 are arranged in a linear array in a plurality of rows, each row being parallel to the central axis of the tube 21. The central axis of each gas pocket 22 and body 21 excircle surface tangent line collineation or parallel set up like this and can make the air current when the gas pocket 22 is being washed out, and the route of air current is along body 21 tangent line flow, can drive liquid and form rivers, except the impact force of direct directional barrel 1 net face, the slant power that still rivers brought more does benefit to and washes away the plug.

During the use, rivers in the barrel 1 are taken out, and the filler of barrel 1 outer suspension is along with rivers flow direction barrel 1's wire side, to export gas in the body 21 this moment, and gaseous recoil will be close to the filler reverse blow-off of barrel 1, can also solve the wadding group problem of long-time deposition formation in the barrel 1 in the same direction as the area simultaneously, and gaseous stirring effect makes the floater be difficult for the conglobation.

Example 2

The difference from embodiment 1 is that the air holes 22 in the pipe body 21 are arranged in a spiral line, and a spiral exhaust path is formed in the pipe body 21.

Example 3

The difference from the embodiment 1 or 2 is that in this embodiment, at least two rows of the air holes 22 are provided in the tube 21, and at most one air hole 22 is located on the same cross section of the tube 21 in two adjacent rows of the air holes 22. That is, the connecting lines between the air holes 22 in two adjacent rows are zigzag, and the holes are alternately formed in a staggered manner. In the present embodiment, four rows of air holes 22 are provided, each row of air holes 22 is disposed parallel to the central axis of the tube 21, and the four rows of air holes 22 are disposed in an annular array on the outer circumferential surface of the tube 21.

Example 4:

the coil pipe 3 that is used for increasing the jet-propelled area is connected with to body 21 one end, and the coil pipe 3 sets up to the circle form, and the one end that body 21 stretched into the staving falls in the centre of a circle of barrel 1 cross section, and the coil pipe 3 is parallel with barrel 1's cross section, and the circular arc profile that coil pipe 3 belongs to sets up with the excircle profile of barrel 1 cross section is coaxial.

The protection scope of the present invention is not limited to the above embodiments, and any modifications, equivalent replacements, and improvements that can be made by a person skilled in the art within the spirit and principle of the present invention should be included in the protection scope of the present invention.
