Abstract
The utility model provides a novel mining wall attachment air duct which comprises an air duct keel. A tensioning contracting channel is arranged in the air duct keel and is connected with a flow guiding channel. Six equal zones are arranged in the air duct keel, namely A is a connecting zone, B is a first compression zone, C is a first-level flow guiding zone, D is a second-level compression zone, E is a second-level flow guiding zone, and F is an outlet. The novel mining wall attachment air duct is ingenious in structure, small in size, light in weight and easy to assemble and disassemble, double-level compression and double-level flow guiding are used, performance is more stable, the whole is in a flow line calabash shape, the tensioning contracting channel is arranged, controllable ventilation and dust control are achieved, fire resistance is achieved, static electricity resistant performance and aging-resistant performance are achieved, durability is achieved, cost is low, and the novel mining wall attachment air duct is suitable for popularization and application.
Description
Technical field
The utility model relates to the pit gear technical field, specifically a kind of new type mining air duct.
Background technology
Present coal mine underground local fan air feed is pressed into the tunnel and meets head on, although played the effect of sparse dust and pernicious gas, also the Air Reverse of dust-laden is pressed onto the tunnel simultaneously, very easily forms circulated air, and serious harm is to the safety in production of mine.Use separately dedusting fan can only siphon away the part dust laden air, still have a large amount of dirty wind and pour into the tunnel.
The utility model content
The utility model purpose provides a kind of new type mining air duct, and it is had can lead by airflow regulation, controls easy and safe and reliable characteristics.
In order to realize the utility model purpose, by the following technical solutions: comprise the air duct keel, in the described air duct keel tensioning constricted channel is set and is connected with flow-guiding channel; It is that bonding pad, B are that the first compressional zone, C are that first order guiding region, D are that compressional zone, the second level, E are that secondary guiding region, F are outlet that district: the A such as six are set in the air duct keel.
Further, described flow-guiding channel is funnel-form.
Described air duct keel are installed high-strength polyester fibers cloth outward.
Described air duct keel are the stainless steel rebar of diameter 6mm.
New type mining air duct of the present utility model, mainly be that the malleation air feed is shunted, a part continues to blow to the effect of meeting head on to play sparse dust and pernicious gas, another part flows out along wall from the wall attachment effect that the side outlet of air duct utilizes air-flow to have when flowing, it is distinguished and admirable to produce immediately spiral, spiral is distinguished and admirable to be rotated along the tunnel perisporium, transversal whole drift section, the distinguished and admirable formation obstacle of spiral, constantly rotation is passed forward, presses to boring head, make dust-contained airflow be locked in the regional area of meeting head on, constantly be inhaled into the negative pressure air duct of deduster, effectively blocked dust-contained airflow and outwards stretched, realized the controllability to dust.
The utility model knows that through repetition test following technological merit is arranged:
(1). this apparatus structure is ingenious, volume is little, lightweight, dismounting is simple;
(2). owing to utilize Two-stage Compression twin-stage water conservancy diversion, performance is more stable;
(3). the utility model is whole to become the streamline calabash shape, and is furnished with the passage that can tensioning shrinks, and realizes controllable ventilated control dirt, has anti-flammability, antistatic, anti-aging, durable, cost is low, and suitable penetration and promotion is used.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model channel design schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further elaborated:
1 comprises the air duct keel among the figure, and the described air duct keel 1 interior tensioning constricted channel 2 that arranges is connected with flow-guiding channel 3; Air duct keel 1 are interior, and district: the A such as six are set is that bonding pad, B are that the first compressional zone, C are that first order guiding region, D are that compressional zone, the second level, E are that secondary guiding region, F are outlet.Described flow-guiding channel 3 is funnel-form.Described air duct keel 1 outer installation high-strength polyester fibers cloth 4.Described air duct keel 1 are the stainless steel rebar of diameter 6mm.The utility model does not describe part in detail and is known technology, and the common variation that those skilled in the art carries out in the technical solutions of the utility model scope or replacement all should be included in the protection domain of the present utility model.
Claims (4)
