Abstract
The invention discloses a rotary screen for a pneumatic rubbish conveying system. The rotary screen comprises a motor, a bucket-shaped shell with a downward opening, a main shaft and a filter drum, wherein the upper part of the bucket-shaped shell is provided with an air outlet; the main shaft is arranged in the middle of the upper end face of the bucket-shaped shell; the filter drum is fixedly connected to the lower end of the main shaft; the filter drum has a grid structure of which the size is matched with that of the bucket-shaped shell; the filter drum is positioned under the bucket-shaped shell; and a ring-shaped air blast groove is formed at the position of the bucket-shaped shell, which is close to the filter drum, and is communicated to the outside of the bucket-shaped shell through a blast pipe which is communicated with the upper side of the ring-shaped air blast groove. The rotary screen can effectively shunt rubbish and air so as to prevent light rubbish, such as paper or plastic bags and the like from entering an air draft unit or a dust catcher through an air pipeline. The ring-shaped air blast groove is formed at the position of the bucket-shaped shell, which is close to the filter drum, air current can be generated at the position through wind power to blow away tiny sundries and prevent piling from affecting the normal running of an entire device so as to improve efficiency.
Description
Technical field
The present invention relates to the device that air draught and rubbish are separated, relate in particular to a kind of rotary screen that is used for pneumatic rubbish conveying system.
Background technology
Pneumatic rubbish conveying system is a kind of modern garbage collection system, and this system utilizes air suctiton ventilator in system, to produce negative pressure, utilizes negative pressure to produce powerful air-flow again; Through the transmission pipeline network of laying in advance; The rubbish that is located at ground all kinds of rubbish dispensing port collections is transported to central refuse collection station, and rubbish separates rubbish and air draught through disconnector; Rubbish falls in the garbage container of back by the compacting machine indentation sealing via gravity; Be sent to garbage disposal place (refuse landfill or garbage burning factory etc.) after filling the garbage container entrucking of rubbish, on the other hand, the gas of carrying rubbish is discharged after through the dedusting deodorizing.Whole flow process is preset by computer program, automatic guidance.Garbage collection process is in sealing state all the time, stops secondary pollution thereby reach, and improves the purpose of urban health environment.
In pneumatic rubbish conveying system, it is very important separating rubbish and air draught effectively, if refuse collection ability and the efficient that can not separate rubbish and air draught the system that will have influence on effectively.
Summary of the invention
The objective of the invention is to the problems referred to above; Propose a kind of rotary screen that pneumatic rubbish conveying system rubbish and air draught separate that is used for, this rotary screen links to each other with flange with this system rubbish disconnector top, and it can be shunted the rubbish that floats with air-flow to rubbish disconnector top effectively with particle and air; Avoid this type rubbish and particle; For example paper or polythene bag etc. get into exhausting unit or dust exhaustor through air duct, have influence on the refuse collection ability and the efficient of system.Simultaneously; The design of filter drum can be walked rubbish and particle bullet effectively; Avoid them can accumulate in the efficient that the filter drum influence is filtered gradually, thereby the high collection efficiency of guaranteeing a whole set of pneumatic rubbish conveying system can and not be affected because of needs timing cleaning and filtering drum.
Technical scheme of the present invention is: a kind of rotary screen that is used for pneumatic rubbish conveying system; Comprise electrical motor, downward opening barrel-shaped housing, main shaft, filter drum; Described barrel-shaped housing top is provided with air outlet, and described main shaft is installed in the middle part, upper surface of barrel-shaped housing, and described filter drum is fixedly connected on the lower end of this main shaft; This filter drum is the grid type structure of mating with barrel-shaped housing size; Filter drum is positioned at the positive bottom of barrel-shaped housing, is provided with the annular arrangement blowing slot at barrel-shaped housing and the approaching place of filter drum, and this annular arrangement blowing slot is communicated to barrel-shaped outside through the blast pipe that is communicated with above it.This annular arrangement blowing slot has two blast pipes to be communicated with it.
Said filter drum high speed rotating, rubbish and particle are filtered bulging bullet and walk, and therefore rubbish and particle can not got into the exhausting unit of this pneumatic rubbish conveying system or seal dust exhaustor through air duct by air outlet.
Rubbish walked by said filter drum bullet and particle makes rubbish and particle also can not stick on the filter drum, and filter drum has been realized the function of automated washing.
Said quilt is at a distance from rubbish and particle outside filter drum, and is floating in air, treats that the rubbish disconnector bottom that falls to this system of nature got into compacting machine and pushes garbage container when pneumatic rubbish conveying system paused.
Described blast pipe is equipped with silencer in the termination of barrel-shaped outside.
Described electrical motor is fixed on the housing outer wall, and electrical motor is given spindle through belt, and described belt outside is provided with protective cover.
Described main shaft outside is provided with the main brass with its coupling, and the upper end of this main brass is fixedly connected on the middle part of barrel-shaped housing upper surface, and described main shaft passes through bearing installation in main brass.
The notch of described annular blowing slot is down over against the top of filter drum, and is gapped between this notch and the filter drum.
The sidewall of described barrel-shaped housing is provided with access hole.
Beneficial effect of the present invention:
The rotary screen that is used for pneumatic rubbish conveying system among the present invention is that the grid type filter through high speed rotating separates lighter rubbish such as rubbish paper and polythene bag; Guarantee that system can be more efficient when collecting rubbish, can not got into the exhausting unit or seal dust exhaustor through air duct by lighter rubbish such as paper and polythene bag.Paper, lighter rubbish such as polythene bag be by at a distance from outside filter drum, and nature falls to compacting machine when treating system-down.
This rotary screen that is used for pneumatic rubbish conveying system is through being provided with the annular arrangement blowing slot at barrel-shaped housing and the approaching place of filter drum; Can produce air-flow at this place through wind-force; Can blow away foreign material, avoid some small garbages in the rubbish to pile up herein, influence the normal operation of entire equipment; Thereby raise the efficiency, and filter drum can be more freely suitable when rotating.
This rotary screen that is used for pneumatic rubbish conveying system is installed silencer on the external end head of blast pipe, the noise that produces when can fully reduce this equipment operation.
