Abstract
The utility model discloses an automatic drainage device for gas drainage and relates to a coalmine gas drainage system which is used for solving the problems that the drainage stability of the gas pipeline is poor, much manpower is needed, the valves wears, and the misoperation probability is high. The automatic drainage device for the gas drainage comprises a PLC (programmable logic controller), an electric relay and a wiring terminal, wherein the PLC is connected with a computer, the electric relay and the wiring terminal are respectively connected with the PLC, the wiring terminal is connected with three special electric gas valves arranged on the drainage devices on a gas inlet pipeline and a gas outlet pipeline respectively, two to five drainage devices are arranged on the gas inlet pipeline and the gas outlet pipeline, three special electric gas valves are arranged on each drainage device, the gas inlet pipeline or the gas outlet pipeline is connected with a water tank through one of the special three electric gas valves, and a special electric gas valve with a small caliber and a special electric gas valve connected with the water tank through a flange are arranged on the water tank. By adopting the automatic drainage device for the gas drainage, the labor quantity and the abrasion of the equipment are reduced, the hidden danger of part ponding of the pipeline is eliminated, and the drainage efficiency is improved; and the operation is simple, the data transmission is fast, and the treatment is timely and in place.
Description
Technical field
The utility model relates to the gas discharge in mine system, is specifically related to a kind of gas drainage under suction self-draining arrangement.
Background technology
In the coal mine gas extraction pipeline,, directly influence the safety in production in colliery, thereby threaten colliery worker's life security because accumulating of condensation ponding is unfavorable for that the down-hole contains the normal discharging of methane gas.
In the existing gas drainage under suction pipeline, be to use manual drainage, poor stability; Need manpower many, valve break-in and maloperation probability are high, and the single operation time is long; Overflow during ponding in the gas drainage under suction pipeline; Flood the situation of damaging instrument and often take place, be unfavorable for that the down-hole contains the normal discharging of methane gas, has a strong impact on and restricting coal mine production safety.
For reducing the loss of unnecessary equipment, alleviate the pressure of ventilation equipment, avoid gas drainage under suction pipe ponding to overflow, be beneficial to the normal discharging etc. that the down-hole contains methane gas, be badly in need of the device that development can effectively solve extraction pump trunk line ponding in the gas discharge in mine process.
Summary of the invention
The utility model is to use manual drainage in order to solve existing gas drainage under suction, and poor stability needs manpower many; Valve break-in and maloperation probability are high; The single operation time is long, overflows during ponding in the gas drainage under suction pipeline, is unfavorable for that the down-hole contains the normal discharging of methane gas; Have a strong impact on the problem of Coal Production, and the gas drainage under suction self-draining arrangement is provided.
The utility model is realized through following technical scheme:
The gas drainage under suction self-draining arrangement; But comprise the PLC programmable logic controller (PLC) that is connected with computer, the relay and the wiring terminal that are connected with PLC editorial logic controller respectively; Wiring terminal respectively be arranged on gas inlet pipe road and extract duct on dewatering installation on 3 electronic gas special valves be connected; Be provided with 2-5 dewatering installation on described gas inlet pipe road and the extract duct; Each dewatering installation is provided with 3 electronic gas special service valves; One of them electronic gas special service valve is connected air inlet pipeline or gas exhaust piping with water tank, water tank is provided with a small-bore electronic gas special service valve, an electronic gas special service valve that connects through flange.
This device is a core control system with the PLC programmable logic controller (PLC), the data at each control point handled and controlled, and through the software control flow system, preset each valve water inlet, draining, blanking time; According to each row of conduits of technological process establishment time sequencing that discharges water, can observe position, the time that drainage system is being operated through computer screen; Improve the accuracy and the stability of drainage system; Eliminate the local ponding hidden danger of pipeline, improve drainage effect, improved drainage efficient.The operator scene generally need not operation, and simultaneously, the signal of down-hole can pass through the looped network plateform system; Send to ground command center, each parameter is adjustable at any time, and each jumps the control point all has on-line monitoring and historical record curve; Had at fingertips to the down-hole running status in the control centre, colliery, and have good grounds; To Safety of Coal Mine Production the important firsthand information is provided.
The utility model is compared with existing system, has the following advantages:
(1) operator's execute-in-place need not to travel to and fro between between working site and the control room, has greatly alleviated employee's the amount of labour;
(2) reduce equipment attrition, eliminated the local ponding hidden danger of pipeline, improved drainage effect, improved drainage efficient;
(3) simple and convenient, data passes fast, handle and be in time, feed back at once and manifest.
