Abstract
The utility model dust falling in coal mining medicament continuous adding device, belong to ratio adding set, be connected in underground coal mine water supply line, this device comprises dust-proof water and crosses the parts such as water pipe, tank body, differential pressure indicator, one way valve, flow director, support, this device has two cover tank bodies, alternation, uninterruptedly can add depositing dust medicament continuously.Described equipment medicament is loaded pipe and is connected tank body by tank body port lid, and dust-proof water is crossed water pipe and is communicated with the first tank body, the second tank body with reducer tee, medicament filling pipe by dosing flexible pipe.The utility model is used for adding a certain proportion of depositing dust medicament in dust-proof water, and this equipment does not need to use electric power, and structure is simple, failure rate is low, good reliability.
Description
Technical field
The utility model belongs to medicament adding technique field, particularly relates to the continuous adding device of dust falling in coal mining medicament, adds depositing dust medicament continuously for crossing to dust suppression in mine water in water pipe.
Background technology
Colliery is the key industry of industrial dust harm, and a large amount of dust produced in down-hole coal excavation, driving, reprinting, transportation not only constitute a serious threat to worker is healthy, and when floating dust reaches finite concentration, meeting burning things which may cause a fire disaster coal-dust explosion can occur.Therefore, controlling floating dust, reducing laying dust is the effective way reducing Occupational Disease Hazards, prevent explosion accident.Utilizing and add the wetability that depositing dust medicament improves dust-proof water, promote the combination of coal dust and water droplet, make floating dust become dust fall and drop to roadway floor, then being caught by dust by washing away laying dust, is the method that underground coal mine is conventional.Underground coal mine water supply aqueduct constant pressure is higher, and it is more difficult that medicament adds pipeline, and existing continuous interpolation equipment is complicated.
Summary of the invention
This device can solve that depositing dust medicament not easily adds, the problem of existing continuous interpolation equipment complexity.
The purpose of this utility model has been come by the following technical programs, and this adding set mainly comprises tank body, pipe loaded by medicament, dust-proof water crosses the parts such as water pipe.
Described tank body is built with medicament poly-bag, and tank body inner support orifice plate is that medicament poly-bag provides support.
Described medicament is dosed on pipe and filling mouth valve, reducer tee, dosing flexible pipe is housed.
Described dust-proof water is crossed on water pipe and differential pressure indicator, pressure-difference valve, section valve, flow director is housed, and it is rack-mount that dust-proof water crosses water pipe, and support is welded on tank body, and tank base welds two square hollow section steels, and two square hollow section steels are welded on installing rack respectively.
Be provided with pressure-difference valve door in this depositing dust medicament adding device, the adjustable dust-proof water of pressure-difference valve door crosses the difference of water pipe inlet pressure and outlet pressure.
Depositing dust medicament adding device is made up of two cover tank bodies, alternation.
The utility model has the advantages that apparatus structure is simple, failure rate is low, easy to operate, good reliability.This device does not need electric power, and the front and back pressure reduction crossing water pipe by dust-proof water completes the interpolation of depositing dust medicament, and energy conservation, is particularly suitable for Working Environment of Underground Mine and uses.
Accompanying drawing explanation
Accompanying drawing 1 and accompanying drawing 2 are the structural representation of the utility model dust falling in coal mining medicament continuous adding device.
In schematic diagram, component part numbers illustrates:
1-dust-proof water crosses water pipe; 2-differential pressure indicator; 3-differential pressure indicator connecting hose; 4-pressure-difference valve; 5-second segment dosing flexible pipe; 6-cuts valve; 7-one way valve; 8-flow director; 9-support plate; 10-support; 11-first paragraph dosing flexible pipe; Pipe loaded by 12-medicament; 13-loads mouth valve; 14-reducer tee; 15-installing rack; 16-protective cover; 17-bolt; 18-tank body port lid; 19-medicament poly-bag; 20-first tank body; 21-square hollow section steel; 22-tapping pipe; 23-emptying valve; 24-supports orifice plate; 25-high-pressure side water filling flexible pipe; 26-Water filling valve; 27-second tank body; 28-backplate.
Detailed description of the invention
Below by using method, the utility model is described in more detail.
Installation instructions
Dust-proof water water pipeline water inlet end connecting downhole carrys out waterpipe, and water side pipe connects the pipeline supplied water to watering equipment, and this device is connected on dust-proof water supply line.
Dose depositing dust medicament liquid and continuous operation process
Close Water filling valve 26 and cut valve 6, open emptying valve 23, open again and load mouth valve 13, load pipe 12 by medicament and dose depositing dust medicament in the first tank body 20, until medicament liquid level rise to load in mouth valve 13 near flashboard time, close and load mouth valve 13 and emptying valve 23, first tank body 20 enters treats running status, open when the depositing dust medicament in the second tank body 27 adds and cut valve 6 and Water filling valve 26, first tank body 20 enters duty, the instruction ball of flow director 8 is beated, then depositing dust medicament liquid is dosed to the second tank body 27, instruction ball when medicament adds in the first tank body in indicator 8 stops beating, now close Water filling valve 26, cut valve 6, first tank body 20 quits work, related valve second tank body 27 opening the second tank body 27 enters duty.
Dosing speed regulates
By regulating pressure-difference valve 4 aperture, carry out pressure reduction adjustment, pressure-difference valve aperture is turned down, and before and after valve, pressure reduction increases, and the amplitude of beating of the instruction ball in flow director 8 increases, and chemical feeding quantity is large, and drug concentration improves, otherwise drug concentration reduces.
