Abstract
A material level detection device of a dry quenching dust remover is characterized by being provided with two pipes including an upper pipe (1) and a lower pipe (2), wherein one end of each of two pipes are respectively connected onto two open holes vertically arranged I the material bin side wall, the other end of each of two pipes is connected with an air inlet pipe (3), ad at least one of two pipes is provided with a flow meter (5) with a switch or a pressure detection switch. The opening positions under two open holes in the material bin side wall are material levels to be detected, and the air inlet pipe (3) is connected with an air source through a throttling valve (4) or directly communicated with the outside through a filter. The material level detection device judges whether the pipe is blocked by materials by detecting air flows or pressure of two pipes or one pipe, a probe is not required to extend into a material bin, and the device is not damaged by the high-temperature materials in the material bin, so that the fault rate is low, the service life is long, the device is not required to be made of a high-temperature-resisting material, and the price is low.
Description
Technical field the utility model relates to a kind of material-level detecting device of dry coke quenching fly-ash separator, particularly the material-level detecting device on the disposable dust remover of coke-oven plant's CDQ device.
On the feed bin of the disposable dust remover of background technology coke-oven plant CDQ device, must install stuff level switch, to detect in time material level, feed bin has been expired will unload ash in time, prevent that dust stratification from too much being taken in waste heat boiler and washing away boiler tube by the recyclegas in the dry coke quenching circulation system, boiler tube is washed wearing and tearing and easily causes the serious accidents such as boiler booster.What in the feed bin due to disposable dust remover, fill is that temperature approaches the high temperature coke powder of 900 degrees Celsius, and therefore, what current each factory was used is condenser type high temperature level-sensing device mostly.From service condition, this high temperature level-sensing device failure rate is higher, damages and often causes disposable dust remover normally not move frequently, owing to unloading the grey safe operation that has even threatened not in time waste heat boiler, and this high temperature level-sensing device price is higher, the rising that frequent replacing can bring production cost.
Summary of the invention the purpose of this utility model is to provide a kind of material-level detecting device of dry coke quenching fly-ash separator, and it does not need to stretch in the feed bin of high temperature and detects, and failure rate is low and cost are also low.The purpose of this utility model is achieved in that it has two pipes, one end of two pipes is connected on respectively on feed bin sidewall by two perforates that are arranged above and below, the other end is connected and is attempted by a draft tube, and two pipes are equipped with flow or pressure detection switch at least one.On feed bin sidewall, in two perforates, the position of opening of below is exactly the material level that will detect, and draft tube is connected clean source of the gas or led directly to atmosphere through filtrator by throttling valve.When work, if material does not arrive below position of opening, enter gas flow or the pressure of feed bin by two pipes basic identical; If material has reached the position of below perforate, below perforate is plugged, and gas flow or pressure that upper and lower two pipes enter feed bin just have relatively big difference, just can judge accordingly material level.This material-level detecting device according to detect two pipes or wherein the size of the gas flow of one or pressure judge whether the pipe of below is blocked by material, thereby judge whether material has arrived detection position, so stretch into feed bin without the need for probe, can not be subject to the infringement of high-temperature material in feed bin, therefore failure rate is low, long service life, and not needing exotic material to make, price is low.
Appended drawings is that in figure, (1) is upper pipe according to the schematic diagram of the embodiment the utility model proposes, (2) be lower pipe, (3) be draft tube, (4) are throttling valve, and (5) are the flowmeters of belt switch.
When embodiment the utility model is arranged on fly-ash separator feed bin, need to open two detection holes one on the other at feed bin sidewall, wherein lower detection hole site is the material level that will detect, the upper pipe (1) of pick-up unit is connected on the upper detection hole of feed bin, lower pipe (2) is connected on the lower detection hole of feed bin, and the pipe diameter and the length that connect use should be identical as far as possible.Draft tube (3) can connect clean source of the gas (as nitrogen or pressurized air), because the disposable dust remover inside of dry coke quenching is negative pressure, so draft tube (3) also can be by the straight-through atmosphere of a filtrator, air inlet sucks by the negative pressure in fly-ash separator.
In embodiment as shown in drawings, when material level in feed bin is during lower than lower detection hole, the negative pressure that detects up and down hole place equates, gas flow in upper pipe (1) and lower pipe (2) equates, the switch of now adjusting on aperture and the flowmeter (5) of intake-air throttle valve (4) is just failure to actuate switch, and this material-level detecting device has just entered duty like this.In the time that the coke powder in feed bin is stacked into lower detection hole site, coke powder is blocked lower detection hole, the air inlet of pick-up unit will all enter feed bin by upper pipe (1), the flow of lower pipe (2) will significantly reduce, switch on flowmeter (5) will move, and sends the signal that feed bin material is full.
The present embodiment is simple in structure, do not contact without wearing and tearing, also do not pop one's head in and stretches into the feed bin of high temperature, so failure rate is low does not need exotic material to make, so production cost is also lower yet.
Claims (2)
1. the material-level detecting device of dry coke quenching fly-ash separator, it is characterized in that: it has two pipes, one end of two pipes is connected on respectively on feed bin sidewall by two perforates that are arranged above and below, and the other end is connected in a draft tube mutually, flow or pressure detection switch is housed at least one of two pipes.
2. material-level detecting device according to claim 1, is characterized in that: draft tube is provided with throttling valve.
