Abstract

The utility model relates to a take out dirt carbon black pipeline, including the dust extraction fill, dust absorption pipe one end is connected to dust extraction fill one end, and the pipe one end is sunk in the connection of the dust absorption pipe other end, and the pipe lower part that sinks is the portion of sinking, and pipe one side that sinks is the dust-retaining wall, sinks to manage the other end and connects out the dirt pipe, sinks to manage and install the check valve with the connection position of dust absorption pipe, and the dust extraction fill is equipped with check valve under the connection position installation of dust absorption pipe, sinks to manage, goes out the intraductal surface spraying special fluorine dragon coating of dirt. The utility model discloses, two check valves have ensured carbon black dust and the small powder dust in the suction carbon black pipeline, can not take place the backward flow, and simultaneously, U type pipeline left side dust wall has kept off the carbon black dust and the small powder dust of backward flow.

Description

Dust-extraction carbon black pipeline

Technical Field

The utility model belongs to the technical field of dust collecting equipment, a take out dirt carbon black pipeline is related to.

Background

The carbon black dust extraction pipeline is used for absorbing carbon black dust and small dust at a charging door of a primary refining machine table, but the phenomenon that the absorbed carbon black flows back from the dust extraction pipeline and is discharged into the air often occurs, and serious pollution is caused to the air.

Disclosure of Invention

An object of the utility model is to provide a take out dirt carbon black pipeline can solve above-mentioned problem, according to the utility model provides a technical scheme: the utility model provides a take out dirt carbon black pipeline, includes the dust extraction fill, dust absorption pipe one end is connected to dust extraction fill one end, the pipe one end that sinks is connected to the dust absorption pipe other end, it is the portion that sinks to sink the pipe lower part, it is the dust blocking wall to sink pipe one side, it connects out the dirt pipe to sink the pipe other end, sink the pipe with the check valve is installed to the connection position of dust absorption pipe, the dust extraction fill with check valve is down installed to the connection position of dust absorption pipe.

As a further improvement of the utility model, the dust absorption pipe, the sinking pipe, go out the interior surface spraying teflon coating of dirt pipe.

As a further improvement of the utility model, the bottom of the sinking pipe is provided with a particle cleaning box.

Compared with the prior art, the utility model, have following advantage:

1. the utility model has simple structure and small occupied space; the two check valves ensure that the carbon black dust and the small material dust pumped into the carbon black pipeline do not flow back.

2. The utility model discloses can keep off the carbon black dust and the small powder dust of backward flow through U type pipeline left side dirt wall.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

In fig. 1, the dust collecting device comprises a dust collecting hopper 1, a dust collecting pipe 2, an upper check valve 3, a sinking pipe 4, a dust outlet pipe 5, a dust blocking wall 6, a lower check valve 7 and the like.

As shown in fig. 1, the utility model relates to a take out dirt carbon black pipeline, including the dust extraction fill 1, the dust extraction fill 1 can enlarge the scope of dust absorption, and dust absorption pipe 2 one end is connected to dust extraction fill 1 upper end, and 4 one ends are connected to the 2 other ends of dust absorption pipe, and pipe 4 is sunk to the pipe 4 that sinks is the U type, and the pipe 4 lower part that sinks is the portion that sinks, sinks to pipe 4 left side for keeping off dirt wall 6, sinks to sink to connect out dirt pipe 5 at the pipe 4 other end.

In order to ensure that the carbon black dust and the small dust precipitated in the sinking pipe 4 do not flow back, a check valve 3 is arranged at the connecting part of the sinking pipe 4 and the dust suction pipe 2.

In order to ensure that carbon black dust and small dust in the dust suction pipe 2 do not flow back, a lower check valve 7 is arranged at the connecting part of the dust suction hopper 1 and the dust suction pipe 2.

In order to reduce the deposition of the pipelines caused by the attachment of carbon black dust and small dust in the pipelines, Teflon coatings are sprayed on the inner surfaces of the dust suction pipe 2, the settling pipe 4 and the dust outlet pipe 5, and the friction force of the inner surfaces is reduced.

In order to conveniently clean the carbon black dust and the small powder dust in the settling pipe 4, a particle cleaning box is arranged at the bottom of the settling pipe 4. When carbon black dust and small powder dust are more in the settling part, the particle cleaning box is cleaned.

The working process of the utility model is as follows: dust collecting equipment is placed at the mouth of a dust outlet pipe 5, and carbon black dust and small powder dust are sucked from a dust suction hopper 1 and are discharged from the dust outlet pipe 5 after passing through a sinking pipe 4 along a dust suction pipe 2. When the dust collection equipment is closed, the residual carbon black dust and small dust in the pipeline are blown by airflow to generate backflow, the dust blocking wall 6 blocks part of the carbon black dust and the small dust in the sinking part at the lower part of the sinking pipe 4, and the rest part of the carbon black dust and the small dust are blocked by the upper check valve 3 and the lower check valve 7 to reduce the backflow.
