Abstract
The utility model relates to a water washing tank with waterless protection function, in particular to a water washing device which is used with a coal-mine explosion-proof diesel engine to purify tail gas of the diesel engine to meet coal mine discharge requirements and resolves problems that a traditional protecting system is unreliable, inaccurate and the like. The water washing tank is equipped with a water-washing tank body, a ball float valve and an air valve. The ball float valve is mounted on the middle position of the water washing tank body, one end of the ball float valve is pressed on the air valve, the other end of the ball float valve is pressed on a ball lever, and one end of the ball lever is connected with a ball float. When purified by the water washing tank body, the tail gas of the diesel engine can take away water in the tank body in water vapor form, and when water level in the tank body is lower than a set value, the ball float is sunk under action of gravity, thereby starting the air valve to generate a stopping alarm signal. The water washing tank can timely, accurately and reliably provide waterless protection signals, prevents accidents caused by untimely signals, realizes safe and normal operation of the explosion-proof diesel engine, and increases safety reliability of the explosion-proof diesel engine.
Description
Technical field
The utility model relates to a kind of water washing box with excessive low water level protection function, is specially a kind ofly to match with anti-explosion diesel engine with the colliery, is used for purification diesel engine tail gas to reach the water washing device of colliery emission request.
Background technique
At present, with the mining equipment of anti-explosion diesel engine as power, adopt (containing flame trap) realizes tail gas the purpose of flame proof, back-fire relief, cleaning of off-gas to reach the safety of coal mines emission standard by water washing box more on the colliery, realizes that green discharges.But traditional excessive low water level protection is arranged on the water supply tank, and the position there is not requirement yet, will occur when water-adding pipe is not smooth like this that water supply tank has water and the phenomenon of water washing box lack of water causes the accident easily.And when float valve was not installed in the casing neutral position, the ramp variation can cause water level fluctuations, thereby influenced the ball float fluctuation, caused undesired shutdown easily.
The model utility content
The purpose of this utility model is to provide a kind of water washing box with excessive low water level protection function, solves problems such as the traditional protection system is unreliable, inaccurate.This water washing box can provide the excessive low water level protection signal in time, accurately, reliably, avoids signal untimely and have an accident, and realizes safety, the proper functioning of anti-explosion diesel engine, improves the peace district reliability of anti-explosion diesel engine, guarantees Safety of Coal Mine Production.
The technical solution of the utility model is:
A kind of water washing box with excessive low water level protection function; this water washing box is provided with washing casing, float valve, air valve; float valve is installed in the neutral position on the washing casing; one end of float valve is crimped on the air valve; the other end of float valve is crimped on the ball lever; one end of ball lever connects ball float, and with the lifting of ball float, ball lever acts on active force on the air valve switch that is fixed on the washing casing by float valve.
Described water washing box with excessive low water level protection function, air valve are fixed on the neutral position on the washing casing.
The beneficial effects of the utility model are:
1, the utlity model has the water washing box of excessive low water level protection function, the excessive low water level protection signal can be provided accurately, reliably, improve the safety reliability of anti-explosion diesel engine work, guarantee Safety of Coal Mine Production.
2, compare with traditional excessive low water level protection device, the utility model is applied in the anti-explosion diesel engine system, can avoid the not smooth and safety in production hidden danger that causes of water-adding pipe.
3; the utility model is mainly by the washing casing; flame trap; float valve; formations such as air valve; the air valve of excessive low water level protection signal will be provided; float valve is installed in the washing casing neutral position that is used for purification diesel engine tail gas; when purifying by the washing casing, diesel engine vent gas the water in the casing can be taken away with the form of water vapour; when the casing middle water level is lower than setting value; ball float sinks in the effect of gravity; air valve is opened produced the warning stopping signal; avoid because of water level fluctuations ball float being exerted an influence on the ramp; guarantee in real time; accurately monitoring water washing box middle water level provides timely; excessive low water level protection signal accurately.
Description of drawings
Fig. 1 is the water washing box structural representation that the utlity model has the excessive low water level protection function.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the side view of Fig. 1.
Among the figure, 1 flame trap; 2 washing casings; 3 float valves; 4 air valves; 5 ball levers; 6 ball floats.
Embodiment
As Figure 1-3; the utlity model has the water washing box of excessive low water level protection function; mainly by flame trap 1; washing casing 2; the air valve 4 of float valve 3 and generation excessive low water level protection signal is formed; washing casing 2 one sides are installed flame trap 1; flame trap 1 passes through gland; bolts etc. are fixed; float valve 3; air valve 4 is installed in the neutral position on the washing casing 2 that is used for purification diesel engine tail gas; one end of float valve 3 is crimped on the air valve 4; the other end of float valve 3 is crimped on the ball lever 5; one end of ball lever 5 connects ball float 6; with the lifting of ball float 6, ball lever 5 acts on active force on air valve 4 switches that are fixed on the washing casing 2 by float valve 3.The utility model realizes mainly that as the matching parts of anti-explosion diesel engine flame proof, back-fire relief, the purification of diesel engine vent gas reduces functions such as exhaust emissions temperature.
Working procedure of the present utility model is as follows:
The utility model water washing box is connected with the exhaust duct of anti-explosion diesel engine band cooling jacket, tail gas is gone into water washing box body 2 by exhaust duct is laggard, certainly to pass through flame trap 1 flame arrest, fire extinguishing earlier, again along washing casing 2 inner custom-designed pipelines mobile also water washing cleaning, cooling, exhaust safely to the external world at last, follow the discharge that purifies back tail gas, can take away a part of water with the form of water vapour.During proper functioning, the water in the water washing box need remain on the water level place of setting, and float valve 3 is subjected to floating function to remain on certain altitude, and by ball lever 5 active force is acted on the air valve 4, makes it be in closed state.When washing casing 2 lacks of water; be that water level is lower than designated water level, ball float 6 sinks with drawdown, and disappear and make air valve unlatching because of acting on active force on the air valve 4 this moment; produce the excessive low water level protection signal, carry out by the protective system that links with it and report to the police, shut down function.
Employing the utlity model has the water washing box of excessive low water level protection function, and the decline of ball float when utilizing drawdown and make air valve open, provide the principle of alarm and protection signal is carried out protective system and reported to the police, shuts down function.Thereby, in real time, accurately monitor the water washing box middle water level and change, provide in time, excessive low water level protection signal accurately, guarantee that anti-explosion diesel engine is in the safety control state.
