Abstract
The invention discloses a mine dustfall agent automatic adding device. The mine dustfall agent automatic adding device comprises a chamber body; a piston is arranged inside a chamber body, divides the chamber body into a first chamber and a second chamber, and is connected with the side wall of the second chamber through a spring; the top of the first chamber is provided with a dustfall agent outlet, the top of the second chamber is provided with a water source inlet, and a water source pipeline is arranged above the chamber body and is communicated with the water source inlet. The mine dustfall agent automatic adding device is particularly applicable to coal mines, is safe in usage, low in costs and high in dustfall efficiency and can adjust the adding proportion of dustfall agents.
Description
Technical field
The present invention relates to a kind of dustfall agent automatic adding device, be specifically related to a kind of for the dustfall agent automatic adding device under coal mine.
Background technology
The dust produced in the coal production process has a strong impact on and is threatening that the safety in production in colliery and miner's is healthy.Some respirable dusts under normal circumstances can be in air suspension dozens of hour, increase in mine oxygen content and reduce pernicious gas content and need to guarantee to ventilate in colliery, so just more encouraged the propagation of dust.
Usually adopt watering and lowering dust in existing colliery, but watering and lowering dust need to be installed a lot of dust falling devices, and long-term watering just can reach the purpose of depositing dust, so just caused some problems: first, increased ambient humidity during a large amount of watering, made personnel suffer from the rheumatic disease probability and increase; In addition, ground is muddy also causes personnel handicapped; The second, the increase of dust falling device causes cost to rise, and safeguards inconvenience.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be suitable for colliery application, use the mining dustfall agent automatic adding device safe, with low cost, that depositing dust efficiency is high, this device in the situation that do not increase other equipment, can be regulated the adding proportion of dustfall agent automatically.
In order to realize above purpose, the present invention adopts following technical scheme: a kind of mining dustfall agent automatic adding device, comprise chamber body, chamber body inside is provided with a piston, piston is divided into the first chamber and the second chamber by chamber body, described piston is connected with the sidewall of the second chamber by a spring, the top of the first chamber offers the dustfall agent outlet, the top of the second chamber offers the water source import, the top of described chamber body also is provided with water pipeline, and water pipeline is communicated with setting with the import of described water source.
Respectively be provided with a flow meter and pressure reduction control valve in described water pipeline and dustfall agent outlet, be connected in series between described flow meter and pressure reduction control valve.
Described the first chamber outer setting is useful on the magnetic fluid level gauge of observing the dustfall agent liquid level.
Mining dustfall agent automatic adding device provided by the present invention, the outlet of the dustfall agent of this device is connected with sprayer, water flows into the second chamber from water pipeline, and the promotion piston moves to the first chamber direction, the driving force that piston produces is added the negative pressure produced while starting sprayer, impels dustfall agent to spray from the dustfall agent exit; In addition, can detect and regulate flow velocity and the flow at water source by flow meter and the pressure reduction control valve arranged on water pipeline, thereby reach the adding proportion of controlling dustfall agent.This device is very suitable for colliery application, and use safe, with low cost, depositing dust efficiency is high.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of mining dustfall agent automatic adding device embodiment provided by the invention.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of mining dustfall agent automatic adding device that the present embodiment provides, comprise chamber body, chamber body inside is provided with a piston 6, piston 6 is divided into the first chamber 5 and the second chamber 10 by chamber body, described piston 6 is connected with the sidewall of the second chamber 10 by a spring 9, the top of the first chamber 5 offers dustfall agent outlet 3, the top of the second chamber 10 offers water source import 8, the top of described chamber body also is provided with water pipeline 7, and water pipeline 7 is communicated with setting with described water source import 8.
In addition, described dustfall agent exit is provided with flow meter 2a and pressure reduction control valve 1a, flow meter 2b and pressure reduction control valve 1b are set on water pipeline 7, serial connection between described flow meter 2 and pressure reduction control valve 1, the first chamber 5 outsides also are provided with the magnetic fluid level gauge 4 for observing the dustfall agent liquid level.
The mining dustfall agent automatic adding device that the present embodiment provides, as long as the dustfall agent outlet is connected with atomization mechanism of the prior art, can be realized the purpose of automatic interpolation, injection control dustfall agent adding proportion.This device is to realize like this regulating the dustfall agent adding proportion: when the dustfall agent adding proportion too high, pressure reduction control valve on adjustable water source capsule road, flow and the flow velocity of pressure being turned down to rear water source reduce, the driving force that flows into its generation in the second chamber when water source is less, thereby increased the difficulty that dustfall agent ejects from the dustfall agent outlet, the dustfall agent ratio in injection apparatus also decreases.
Claims (3)
1. a mining dustfall agent automatic adding device, it is characterized in that, comprise chamber body, chamber body inside is provided with a piston, and piston is divided into the first chamber and the second chamber by chamber body, and described piston is connected with the sidewall of the second chamber by a spring, the top of the first chamber offers the dustfall agent outlet, the top of the second chamber offers the water source import, and the top of described chamber body also is provided with water pipeline, and water pipeline is communicated with setting with the import of described water source.
2. mining dustfall agent automatic adding device according to claim 1, is characterized in that, in described water pipeline and dustfall agent outlet, respectively is provided with a flow meter and pressure reduction control valve, between described flow meter and pressure reduction control valve, is connected in series.
3. mining dustfall agent automatic adding device according to claim 1 and 2, is characterized in that, described the first chamber outer setting is useful on the magnetic fluid level gauge of observing the dustfall agent liquid level.
