Abstract
The material-level detecting device of cork dry quenching disposable dust remover, it comprises two detector tubes be arranged above and below, a flow detector two detector tubes is respectively equipped with, it is characterized in that: described flow detector comprises two two-position three way magnetic valves (1) and (2), thermistor (6) and (7) are provided with as flow detecting element at the R mouth (1R) of solenoid valve and (2R), the P mouth (1P) of solenoid valve and (2P) connect Nitrogen source gases, and the A mouth of solenoid valve connects described detector tube.The utility model adopts thermistor as flow detecting element, and be arranged on the R mouth of two-position three way magnetic valve, time normal, thermistor detects charge flow rate, purges when solenoid valve obtains electric with nitrogen to draft tube, and therefore this material-level detecting device compact conformation, volume are little.
Description
Technical field the utility model relates to the material-level detecting device of the disposable dust remover of a kind of coke-oven plant CDQ device.
The feed bin of the disposable dust remover of background technology coke-oven plant CDQ device must install stuff level switch, to detect material level in time, feed bin has been expired will unload ash in time, prevent dust stratification from too much being taken in waste heat boiler by the recyclegas in the dry coke quenching circulation system and wash away boiler tube, boiler tube is washed wearing and tearing and easily causes the serious accidents such as boiler tube bursting.Be temperature close to the high temperature coke powder of 900 degrees Celsius due to what fill in the feed bin of disposable dust remover, therefore, what current each factory used is condenser type high temperature level-sensing device mostly.From service condition, this high temperature level-sensing device failure rate is higher, damages frequently and often causes disposable dust remover normally not run, and unloads ash and has even jeopardized the safe operation of waste heat boiler not in time, and this high temperature level-sensing device price is higher, frequent replacing can bring the rising of production cost.
For solving the problem, the patent No. is the material-level detecting device that the utility model patent of 201420016405.X provides a kind of dry coke quenching fly-ash separator, it has two pipes, namely detector tube and lower detector tube is gone up, one end of two pipes is connected on feed bin sidewall respectively by two perforates be arranged above and below, the other end is connected in a draft tube mutually, two pipes at least one is equipped with flowmeter or the pressure detection switch of belt switch, and draft tube connects source of the gas by throttling valve or leads directly to air through filtrator.This material-level detecting device by detect two pipe or wherein the gas flow of one or the size of pressure judge below pipe whether blocked by material, feed bin is stretched into without the need for probe, also the infringement of high-temperature material in feed bin can not be subject to, therefore failure rate is low, long service life, and not needing exotic material to make, price is low.Above-mentioned material-level detecting device Problems existing is: detecting element have employed flowmeter or the pressure detection switch of belt switch, so volume is comparatively large, cost is also high, in addition, must arrange purging solenoid valve in addition to ensure that detector tube is unimpeded, this more can the volume of aggrandizement apparatus.
Summary of the invention the purpose of this utility model is to provide a kind of material-level detecting device of cork dry quenching disposable dust remover, and flow detecting element and purge solenoid valve are integrated by it, with the volume of reduction means.The purpose of this utility model is achieved in that and is all provided with flow detector on two detector tube, described flow detector comprises two-position three way magnetic valve, the R mouth of solenoid valve is provided with thermistor as flow detecting element, the P mouth of solenoid valve connects Nitrogen source gases, and the A mouth of solenoid valve connects described detector tube.The utility model adopts thermistor to be flow detecting element, and be arranged on the R mouth of two-position three way magnetic valve, charge flow rate is detected with thermistor during work, when upper and lower detector tube flow is equal, thermistor resistance is equal, if lower detector tube is blocked by coke powder, then its thermistor resistance can change, and interlock circuit detects that two thermistor differences just send " buying securities with all one's capital " signal after exceeding certain value.Need when purging, solenoid valves nitrogen to be purged detector tube.Because flow detecting element of the present utility model (thermistor) is directly installed on purge solenoid valve, therefore this material-level detecting device compact conformation, volume are little, and cost is low.
Appended drawings is the schematic diagram according to the embodiment that the utility model proposes, in figure, (1) be the solenoid connecting detector tube, (2) be the lower solenoid valve connecing lower detector tube, (1R) be the R mouth of solenoid, (1P) be the P mouth of solenoid, (2R) be the R mouth of lower solenoid valve, (2P) be the P mouth of lower solenoid valve, (3) be bus-bar, two solenoid valves are all installed on the busbar, (4) be draft tube bus-bar connecting two solenoid valve R mouths, (5) be the draft tube (connecing Nitrogen source gases) bus-bar connecting two solenoid valve P mouths, (6) thermistor of solenoid R mouth is mounted in, (7) thermistor of lower solenoid valve R mouth is mounted in.
Embodiment is in embodiment of the present utility model as shown in drawings, two solenoid valves (1) and (2) are arranged on bus-bar (3) side by side, both R mouths have common draft tube (4) like this, both P mouth has common Nitrogen source gases draft tube (5), the A mouth of two solenoid valves is (at the solenoid valve back side, not shown in FIG.) two detector tubes respectively on the sidewall of splicing storehouse, two thermistors (6) and (7) are arranged on the R mouth place of two solenoid valves respectively.During detected state, the A mouth of solenoid valve communicates with R mouth, owing to having negative pressure in feed bin, so outside gasses enters in feed bin by draft tube (4), solenoid valve R mouth, A mouth, detector tube; During purging state, solenoid valve obtains electric, and A mouth and R mouth disconnect, and A mouth is communicated with P, so nitrogen enters feed bin by draft tube (5), P mouth, A mouth, detector tube, purges detector tube, prevents blocking.In the present embodiment, in feed bin time material level low (not blocking up lower detector tube), the gas flow that two solenoid valve R mouths enter feed bin is substantially equal, and the temperature of two thermistors is substantially equal, so its resistance is also substantially equal, when the charge flow rate of material level in feed bin high (blocking up lower detector tube) solenoid valve (2) is at present zero, and the flow of solenoid (1) is constant or corresponding increase, so the temperature of thermistor (7) raises, there is larger change in resistance, and the resistance of thermistor (6) is substantially constant, corresponding control circuit detects that the resistance difference of two thermistors changes to a certain degree can send the full signal of feed bin afterwards, just ash discharge can be carried out, after ash discharge, material level declines, lower detector tube opens up, the air inlet of lower solenoid valve (2), the resistance of its thermistor (7) just returns to normal condition, diminish with the difference of thermistor (6), circuit just stops sending the full signal of feed bin.
In order to ensure the unimpeded of detector tube, control circuit should purge regularly to the coil electricity nitrogen of solenoid valve to detector tube.
In addition, above-mentioned detection device should be contained in a housing, so nitrogen inlet duct is preferably arranged a variable valve, the nitrogen that outwards release is appropriate is continued with this variable valve, make to be full of nitrogen in the housing of whole device, such one side prevents the dust of outside from entering housing, ensures that the gas entering detector tube is all nitrogen on the other hand, prevents entering air and cause high temperature coke powder to burn.
Flow detecting element and thermistor are arranged on the R mouth of two-position three way magnetic valve by the utility model, achieve detecting element and purge unit integral, so greatly reduce equipment volume, also reducing cost simultaneously.
