Description
The utility model relates to a kind of mine depositing dust safety device, is the automatic injection device of a kind of relative pressure method solution specifically.
For strengthen labour protection, protection and guarantee the healthy of labourer, now in the mining activity place (as under the coal mine) adopt wet mining to reduce dust concentration usually, the general automatic injection device of relative pressure method solution is as shown in Figure 2.It comprises feed pipe and coupled logical solution container.In this device, be that a certain section water pipe internal diameter of feed pipe diminished, make it under certain water supply flow situation, to produce enough water velocities.When in pipeline, flowing based on fluid media (medium), flow velocity is big more, the principle that pressure is low more, when flow velocity is enough high in the pipeline that dwindles, the pressure of its current can be lower than the pressure of waiting to annotate in the solution container, thereby make in the automatic flow in pipes current of depositing dust agent in the solution container, to inject the depositing dust agent solution in the current that are implemented in feed pipe.Yet, this device exists significant disadvantages, significant disadvantages is that pressure in the feed pipe is often much larger than a standard atmospheric pressure, sometimes even near 10 standard atmospheric pressures, this just requires dwindling the pipeline section caliber and will designing very for a short time of feed pipe, could produce enough big water velocity, form enough low pressure.Like this, dwindle internal diameter of the pipeline, unavoidably strengthened whole water system resistance, make the output of water system not reach requirement.This shows that this device not only has shortcoming, or even infeasible.
The purpose of this utility model provides and a kind ofly can make the water system resistance little again with waiting that annotating solution injects automatically, and output is big, and solution to be annotated can also be deposited the automatic injection device of relative pressure method solution of dress separately.
For achieving the above object, the utility model is achieved in that the automatic injection device of a kind of relative pressure method solution, it comprises main-supply and coupled logical solution container, wherein, the stage casing of main-supply is an amplifier tube, its two ends are connected with main-supply respectively, be provided with a deformable barrier film in the solution container, the solution container is divided into solution storage chamber and water body storage chamber, and the volume of solution storage chamber is equal to or greater than 1/2 of solution container volume, have the hole of exerting pressure on the amplifier tube, it is communicated with the pressurized hole that the water body storage chamber of solution container is offered, and the solution storage chamber of solution container is communicated with the main-supply downstream.
The outstanding advantage of the utility model is:
1. be communicated with certain section feed pipe internal diameter amplification and with the solution container, both realized that waiting to annotate solution injects automatically, can not cause whole water system resistance to increase again, the assurance water system is normally carried out;
2. in the solution container deformable membrane is arranged, the solution container is divided into solution storage chamber and water body storage chamber, both guaranteed that waiting to annotate solution deposited dress separately, realize the pressure transmission between interior water body of container and solution again, thus the stable injection that assurance waits to annotate solution;
3. the utility model is easy, effective, economical.
Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:
Fig. 1 is the automatic injection device structural representation of relative pressure method solution provided by the utility model;
Fig. 2 is the known automatic injection device structural representation of relative pressure method solution.
As shown in Figure 1, the automatic injection device of a kind of relative pressure method solution, it comprises main-supply 1 and coupled logical solution container 3.Wherein, the stage casing of main-supply 1 is an amplifier tube 2, and its two ends are connected with main-supply 1 respectively.Be provided with a deformable barrier film 4 in the solution container 3 solution container 3 is divided into solution storage chamber and water body storage chamber, and the volume of solution storage chamber is equal to or greater than 1/2 of solution container 3 volumes.Have the hole 11 of exerting pressure on the amplifier tube 2, connect the mouth of exerting pressure, it is communicated with by the set pressurized hole 12 in communicating pipe 15 and water intaking valve 9 and the water body storage chamber of solution container 3, and the solution of solution container 3 is store the chamber and passed through tapping valve 8 and be connected with the set injection nozzle 13 in another communicating pipe 16 and main-supply 1 downstream.Be provided with fluid flowmeter 14 at tapping valve 8 and between communicating pipe 16, store on chamber and the water body storage chamber at the solution of solution container 3 and be respectively equipped with charging valve 7 and draining valve 10.
Wait to annotate the situation that solution injects automatically as can be seen from Figure 2 in the solution container 3 in water system.According to the fluid pressure transfer principle, pressure in the amplifier tube 2 and solution container 3 interior pressure equate, be equal to P1, because of amplifier tube 2 internal diameters greater than main-supply 1 internal diameter, then the water velocity in the amplifier tube 2 is lower than the water velocity in the main-supply 1, based on hydromechanical bernoulli principle, pressure P1 in the amplifier tube 2 is then greater than the pressure P2 in the main-supply 1, so pressure P1 is greater than pressure P2 in the main-supply 1 in the container 3, because the existence of this pressure reduction is waited to annotate solution 6 and can be injected main-supply 1 automatically by injecting 13 at nozzle.Injection rate can be by fluid flowmeter 14 observations.
Waiting that annotating solution injects main-supply 1 process automatically, wait to annotate solution in the container 3 and reduce its storage capacity because of constantly injecting feed pipe 1, be the balance that keep-ups pressure, the current of amplifier tube 2 can replenish to container 3 naturally, deformable membrane 4 can make solution pressure equate all the time that with amplifier tube 2 interior pressure keep between solution and main-supply 1 current has certain pressure reduction always with solution interface generation deformation in the container 3 in addition, so can guarantee to wait to annotate the abundant injection of solution, till having annotated.When adorned wait that annotating solution has annotated after, close water intaking valve 9 and tapping valve 8 simultaneously, open container draining valve 20 and charging valve 7, liquid feeding again.In the liquid feeding process, because deformable membrane 4 is added the discharge gradually of the extruding of solution and water body and is returned to the home position gradually, till can guaranteeing that solution to be annotated is filled it up with, at this moment, again close draining valve 10 and charging valve 7 and open water intaking valve 9 and tapping valve 8, can wait to annotate the current that solution injects water supply line 1 once more automatically again.Establish a deformable barrier film 4 in solution container 3, its kinetic energy and effect are that the water body that will wait to annotate inflow in solution and the amplifier tube 2 in the solution container 3 separates naturally, and do not influence the pressure transmission between water body medium and the solution medium.Barrier film 4 is by a metal framework and solution container 3 inwall tight fits.Even for pressurized around making that deformable membrane 4 contacts with water body, be provided with porous rest layer 5 at the suitable spacing place of solution container 3 inwalls.
The utility model has the embodiment of success:
Example 1. amplifier tube internal diameters are φ 100mm (length 1.5m),
