CN205649959U - A broken bag detection device for bag collector - Google Patents

Abstract

The utility model discloses a broken bag detection device for bag collector, it includes dust collection tube, end cap and pipe cap, dust collection tube (1) is the steel pipe, and steel pipe top -down is equipped with two sections air vent (2), and every section air vent is all evenly laid threely around the steel pipe with 120, the steel pipe bottom is by end cap (3) shutoff, and the upper end is by pipe cap (4) shutoff. Because the wind speed of air -purifying chamber and exhaust passage junction is in and distinguishes from low -speed to fast -speed transition in the bag collector casing, so can know according to hydrodynamics that air current here can form the torrent of circling round a part and can directly not take away the dust. Consequently, install this detection device in here, when the dust passes through, according to the principle of reflection its can be timely get off the dust entrapment, be convenient for observe the current behaviour in service of filter bag, its simple structure, the preparation is easy, low cost, convenient to use is reliable, effectual.

Description

A kind of broken bag for sack cleaner detects device

Art

This utility model relates to a kind of detection device, detects device particularly to a kind of broken bag for sack cleaner.

Background technology

Sack cleaner is the special dust-removing equipment that a kind of range is wide, efficiency of dust collection is high.Its Cleaning mechanism is: high pressure draught and injection air-flow that pulse valve ejects rapidly enter filter bag, makes filter bag drastically expand generation vibration, and the effect adding superinverse air-flow makes the dust releasing on filter bag get off, thus completes deashing work.If but the filter bag of certain filter chamber once occurs breakage, dust will be entered in Gas-cleaning box by damaged filter bag, thus directly affects the operational effect of cleaner.As can be seen here, find and change in time the filter bag of breakage in time, be to ensure that the key that cleaner is properly functioning.At present, the detection to cleaner unit damaged filter bag, mostly use laser detector.This laser detector is the most expensive, system complex, and itself fault rate is high, and the most really put into operation is few.

Utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, it is provided that the broken bag for sack cleaner that a kind of low cost, convenient and reliable operation, and using effect are good detects device.

Its technical scheme is: a kind of broken bag for sack cleaner detects device, it is characterised in that: include dust collection pipe, plug and pipe cap；Described dust collection pipe is steel pipe, and steel pipe is provided with two sections of passages from top to bottom, every section of passage all around steel pipe with 120 ° of uniform layings three；Steel pipe bottom is blocked by plug, and upper end is blocked by pipe cap.

During use, this detection device only need to be installed on air-purifying chamber and the pulse valve side of air outlet junction in sack cleaner housing.

It provides the benefit that: owing in sack cleaner housing, the wind speed of air-purifying chamber and junction, exhaust passage is exactly in from low speed (≤3m/s) to the transition region of (>=8m/s) at a high speed.Understanding air-flow herein according to hydrodynamics and can form the turbulent flow of a kind of local convolution, dust will not directly be entrained by the flow of air, but circle round a period of time herein.Therefore, this detection device is installed on herein, just can well allow air-flow pass through according to the passage that physical dimension calculates；And when there being dust to pass through, according to principle of reflection, dust catching can be got off by timely, and it is retained in for a long time in collecting pipe.Therefore when cleaner overhauls, the maintenance door of each pocket need not be opened, only the pipe cap of this detection device need to be disassembled, will know that the behaviour in service that filter bag is current: if it find that dust collection pipe exists dust, i.e. illustrate that this room exists broken bag phenomenon.After changing bag, the plug of this detection bottom of device is unloaded, and after dust collection pipe is cleaned up, can reinstall, reuse;And its simple in construction, make easily, with low cost, easy to use and reliable, effective.

Detailed description of the invention

As shown in Figure 1, 2, a kind of broken bag for sack cleaner detects device, including dust collection pipe, plug and pipe cap.Described dust collection pipe 1 uses that to be used for catching and store the specification of dust be 2 " steel pipe.Steel pipe is provided with two sections of passages 2 from top to bottom, every section of passage all around steel pipe with 120 ° of uniform layings three.Passage is calculated by wind speed according to geometry principle of reflection and dust, to ensure that dust is collected through out-of-date can seizure by dust collection pipe.Steel pipe bottom is blocked by dismountable plug 3, to facilitate dismounting and the dust cleared up in dust collection pipe.Upper end is blocked by pipe cap 4, in order to dust collection pipe and the connection of shell of dust remover also ensure the easy accessibility of dust collection pipe and good air-tightness.

During use, this detection device A only need to be installed on the C side of air-purifying chamber B and air outlet D junction in sack cleaner housing and get final product (see figure 3).

Claims (2)

1. the broken bag detection device for sack cleaner, it is characterised in that: include dust collection pipe, plug and pipe cap；Described dust collection pipe (1) is steel pipe, and steel pipe is provided with two sections of passages (2) from top to bottom, every section of passage all around steel pipe with 120 ° of uniform layings three；Steel pipe bottom is blocked by plug (3), and upper end is blocked by pipe cap (4).

A kind of broken bag for sack cleaner the most according to claim 1 detects device, it is characterised in that: described dust collection pipe (1) uses specification to be 2 " steel pipe.
