Description

Mining deduster

One, technical field

The utility model relates to a kind of mining deduster, is mainly used in the dedusting of the channel of coal mining working surface of explosion risk.

Two, background technology

Channel of coal mining working surface is that dust is concentrated the operation place that generates in a large number.The mine air dust all can bring serious threat to health and production safety, and the air purification dedusting of getting working face is an important process of Safety of Coal Mine Production.

The extractive equipment that use in present domestic colliery is typically equipped with inside and outside spraying dust firing device, but in actual use, faults such as internal spraying often stops up, leakage, a large amount of external sprayings not only causes operation place ponding, and stopping operating personnel's observation sight line, the dirt effect of therefore totally going out is all undesirable.

Getting working face is also less use special dust-removing equipment at present, existing getting working face special dust-removing equipment is owing to be subjected to the on-the-spot restriction of unfavorable conditions in many ways, all merely adopt plain type wet dust removal method, the subject matter of its existence is: compare with the dry dust removal method, wet dust removal method efficiency of dust collection is lower, especially more low for the respirable dust efficiency of dust collection, simultaneously, also need a large amount of water supply, increased the weight of the ponding problem in operation place, and most cleaners can not be fine supporting with work plane extractive equipment and ventilation system, dust removing effects is very undesirable, and this also is to cause at present existing special dust-removing equipment to use one of less reason at getting working face.

Therefore, the air ambient of domestic most of getting working faces is very abominable at present, can not satisfy the requirement of " safety regulations in coal mine ", development is suitable for the new exclusive high-effective dust-removing equipment that channel of coal mining working surface uses, for the air ambient that improves getting working face, guarantee that the safety in production in colliery is significant.

Three, utility model content

1. goal of the invention

Deficiency in view of existing dust collection method of channel of coal mining working surface and equipment existence, the purpose of this utility model is by integrated use dry type screening and dedusting method, inertial dust collection method and various explosion precaution, the mining deduster of explosion-proof type of a kind of efficiency of dust collection height, dry type (not needing the water source), channel of coal mining working surface special use is provided, so that the air-borne dust content of getting working face satisfies the requirement of " safety regulations in coal mine ", the safety in production in assurance colliery and field operation personnel's is healthy, improves the getting working face operating environment.

2. technical scheme

The technical program mainly comprises flame-proof mine exhaust ventilation machine, dry type worry dirt device, towing slide device etc.Ventilation fan butts up against the deduster back by flange or flexible pipe, and the two is seated on face conveyor ledge or the slideway by the towing slide device, together with being moved by the extractive equipment traction into and out of air duct integral body of two ends.Dry type consider the dirt device by consider the advancing of dirt case, disposal box and two ends, exhast duct is formed.Worry dirt case mainly revolves tube, motor and transmission device etc. by casing, rotatable filtration to be formed, considering the dirt case is seated on the disposal box, revolve screen pack on the tube and the sealing device cleaned air after with dust laden air and dust removal by filtration by filtration and isolate, form an inlet chamber and a discharge chamber respectively.Filtration is revolved tube by the Motor Drive rotation, and several filtrations are revolved tube and spatially are arranged in parallel, assembled arrangement, and its quantity is determined according to the size of handling air capacity.Filtration is revolved tube and is adopted electric conductivity good metal screen pack and metallic support rack, when rotating at a high speed, can not produce static focus, add distinguished and admirable cooling effect and adopt flame-proof mine exhaust ventilation machine, thereby can satisfy the requirement of explosion proof of channel of coal mining working surface.

After ventilation fan starts, dust laden air is at first considered dirt device air inlet duct by dry type and is sucked the inlet chamber of considering in the dirt case, dust granules is under the drive of the screen pack that rotates at a high speed, get rid of on the sidewall of casing by powerful centrifugal inertia throwing, assembling the back falls in the disposal box along sidewall naturally, automatically intermittently discharge outside the case continuously or manually by wherein deashing, dust exhaust, fall on the transporter and transport with material, the negative pressure that cleaned air produces by the exhaust ventilation machine sees through screen pack and enters discharge chamber, discharge via the exhast duct of considering the dirt device, exhaust ventilation machine, finish dust removal process.

3. technique effect

The utility model is applied to channel of coal mining working surface with dry type dust removal by filtration and inertial dust collection method in a creative way, the efficiency of dust collection and the air purification effect of getting working face have been improved significantly, the external spraying device of extractive equipment can reduce spray amount, even close fully, again owing to itself do not need to supply water, thereby solved the ponding problem of operation field basically, guaranteed simultaneously requirement of explosion proof again, thereby reach the requirement that the air-borne dust content that makes getting working face satisfies " safety regulations in coal mine ", the safety in production in assurance colliery and field operation personnel's is healthy, improve the effect of getting working face operating environment, have outstanding Technological Economy and social benefit, have a extensive future.

The utility model with compare with existing various dust collection methods and equipment, have obvious superiority and applicability.
