Abstract

The utility model discloses a manhole subassembly with double -deck filter screen, including manhole seat, manhole cover, fastening handle, outer filter screen and interior filter screen, the flange ring has been welded on the manhole seat inner wall, outer filter screen is placed on the flange ring concave surface, interior filter screen embedding is outside in the filter screen, the manhole cover covers on the manhole seat, and the manhole cover is through fastening handle press the sealing. The utility model discloses a cooperation of inside and outside double -deck filter screen is used, can realize two kinds of filter fineness requirements, has sealed effect simultaneously concurrently, can carry out effective filtration to liquid material such as the pitch of filling, fluid, has avoided personnel to advance a jar disentanglement operation to the function of ordinary manhole has been expanded in easily dismouting, satisfies maintenance mechanical equipment fog seals constructions such as asphalt spraying car, synchronous seal car very much and uses needs.

Description

There is people's aperture member of double-layer leaching net

Technical field

This utility model relates to the tank structure on a kind of Maintenance Machinery, specifically a kind of people's aperture member with double-layer leaching net.

Background technology

Current Maintenance Machinery product such as pitch sprinkling car, synchronous macadam seal paver all refer to the use of tank body people's aperture member. Existing people's aperture member is usually the filler as tank body liquid and personnel enter the maintenance entrance of tank, does not have filtration, it is impossible to filling liquid is effectively filtered. In actual filling process, the liquid impurity such as the Colophonium that may fall into foreign material or filling are too much, it is thus desirable to personnel often enter tank cleaning foreign material or other impurity, if clearing up not in time, operation may block valve, bitumenpump and asphalt nozzle, cause corresponding damage, have a strong impact on construction operation.

Summary of the invention

For above-mentioned prior art Problems existing, this utility model provides a kind of people's aperture member with double-layer leaching net, use and mounting or dismounting are convenient, can the liquids such as the Colophonium of filling, fluid effectively be filtered, it is to avoid personnel enter tank prune job.

To achieve these goals, the technical solution adopted in the utility model is: a kind of people's aperture member with double-layer leaching net, including manhole collar, manhole cover, pinch grip, outer leaching net and Inner filter net; Described manhole collar's inwall is welded with flange ring; Described outer leaching net is placed on flange ring concave surface; Described Inner filter net is embedded in outer leaching net; Described manhole cover covers on manhole collar, and manhole cover is compressed by pinch grip and seals.

This utility model is further, and described Inner filter net is provided with flange, and flange has two otch, described outer leaching net is welded with two and matches with otch to limit the little round steel beated.

This utility model is further, and described Inner filter net is welded with carrying handle.

This utility model is further, has sealing gasket between flange ring and the manhole cover of described manhole collar.

This utility model is further, and described outer leaching net mesh diameter is more than Inner filter net mesh diameter.

Compared with prior art, this utility model by inside and outside double-layer leaching net with the use of, two kinds of filtering accuracy requirements can be realized, have sealing effectiveness concurrently simultaneously, the Colophonium of filling, the liquid such as fluid effectively can be filtered, it is to avoid personnel enter tank prune job, and are prone to dismounting, expand the function of common manhole, meet the Maintenance Machinery equipment mist sealing construction usage needs such as pitch sprinkling car, synchronous chip sealer especially.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, this utility model has people's aperture member of double-layer leaching net, including manhole collar 1, manhole cover 2, pinch grip 4, outer leaching net 5 and Inner filter net 6; Manhole collar 1 inwall is welded with flange ring 1-1; Outer leaching net 5 is placed on flange ring 1-1 concave surface; Inner filter net 6 is embedded in outer leaching net 5; Manhole cover 2 covers on manhole collar 1, and manhole cover 2 is compressed by pinch grip 4 and seals.

On said structure basis, as in figure 2 it is shown, this utility model is provided with flange 6-2 on Inner filter net 6, flange 6-2 has two otch, described outer leaching net 5 is welded with two and matches with otch to limit the little round steel 5-1 beated. Inner filter net 6 upper cut being directed at the round steel 5-1 on outer leaching net 5, can put it on the concave surface 5-2 of outer leaching net 5, under slightly rotating, such round steel 5-1 plays the effect that restriction Inner filter net is beated.

Inner filter net 6 is welded with carrying handle 6-1, facilitates personnel to carry out mounting or dismounting Inner filter net 6, outer leaching net 5.

There are sealing gasket 3, sealing gasket 3 to avoid pushing down Inner filter net 6, outer leaching net 5 between the flange ring 1-1 and manhole cover 2 of manhole collar 1, are otherwise not easy to the mounting or dismounting of Inner filter net 6, outer leaching net 5.

In double-layer leaching net, outer leaching net 5 mesh diameter is more than Inner filter net 6 mesh diameter, it is possible to according to actual needs, only uses outer leaching net 5, it is also possible to the combination of outer leaching net 6, Inner filter net 5 uses, such that it is able to realize two kinds of filtering accuracies. Can better meet the construction needs of pitch sprinkling car, synchronous chip sealer.

Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment on this basis according to actual needs, thus obtaining different embodiments. Owing to mode in the cards is more, just no longer illustrate one by one here.
